This solution, which not only increases the amount of bubbles using the jet, is also useful for removing debris from the hull. A swirl segment from a nozzle is arranged as a spiral passage, and the swirl segment is gradually reduced from water inlet to water outlet, further increasing the velocity of the liquid. The volume of the pipe chamber in the barrel is different and the liquid is pulsed as it flows through the barrel. Thus, the liquid is eventually ejected through the nozzle of a cleaning gun, providing an effective improvement of the cavitation rate and increasing the generation of cavitation cores. A hollow, rotating shaft of a cleaning plate is provided with a redirect passage, and the inside of the redirect passage is provided with several arcuate strips. The hollow rotating shaft pushes the liquid downward, and the liquid also imposes an opposite pressure on the cleaning plate, which is beneficial for the cleaning plate's ability to float on water.

    BACKGROUND When large vessels have been at sea for many years, a thick layer of debris is formed on the part of the hull that is below the surface of the water, and also inevitably a large area of corrosion is created. Therefore, old coatings, peels and rust should generally be removed when large vessels are applied, after which new paint is applied to ensure the ship's sailing ability and extend its service life. In recent years, with the development of pressurized jet technology, this technology has mainly been used in the shipping industry.

Coating, peeling, rust and paint can be quickly removed via the strong contact force, erosion force and removal properties from the water jet. Although prior art can increase the pressure of the water flow, the current cavitation jet technology encounters a bottleneck as the water pressure of the apparatus is not easily improved due to the technical limitations. which the pump and gun make up. Thus, the problems of how to improve the cavitation beam effect, increased efficiency in underwater work and the cleaning effect are what professionals in the field are researching for solutions.

    GB 2019 70456 A1 usable for removing dirt from hulls. A vortex segment from a nozzle is arranged as a spiral passage, and a high velocity eddy current is formed when the high pressure fluid is sprayed out of the nozzle. a lot of bubbles (cavitation cores). The bubbles cause a strong micro-jet effect on the cleaned ship surface as soon as the bubbles burst. Due to the special arrangement of the nozzle, the flow velocity of the nearby micro-jet can reach 90 to 185 m / s. When the bubbles generated by the cleaning gun burst, the micro-jet effect of the surface increases approx. 100-1000 times / (s cm 2) , effectively removing hard dirt and debris. In the present invention, the passage in the barrel is formed by joining several spherical chambers. The diameter of the connecting portion of two adjacent spherical chambers is smaller than the diameter of each spherical chamber. Thus, the liquid is eventually ejected through the nozzle of a cleaning gun, providing an effective improvement of the cavitation rate and increasing the generation of cavitation cores.
    The cleaning gun is additionally equipped with a miniature vibrator, two plate-shaped conductors and a vibration power supply. The electrodynamic miniature vibrator allows the cleaning gun to eject the flow of water in such a way as to create an intermittent eddy current segment, which increases the formation of cavitation cores. A pipe is arranged between the syringe and the barrel to play a role in the diversion and as a buffer, reducing the effect of the syringe vibration in the barrel. One end of the barrel close to the syringe is equipped with an automatic heating unit. When the water temperature is lower than the preset value, the water is heated in the barrel by means of an electric heating plate to reach the set temperature, in the range of 27 ° C to 38 ° C. At this temperature, the optimum cavitation effect can be obtained by using the water as a medium if the viscosity and surface tension thereof are omitted.
    A hollow, rotating shaft of a cleaning plate is provided with a redirect passage, and the inside of the redirect passage is provided with multiple arcuate strips so that the flow of water forms an eddy current in the hollow, rotating shaft and is then ejected from the lower end, and then the high velocity oscillating fluid is exposed to radiation cavitation.
    DK 2019 70456 A1 For this, the hollow rotating shaft pushes the liquid downwards, and the liquid also imposes an opposite pressure on the cleaning plate, which is beneficial for the cleaning plate's ability to float on water. In this way, due to the many light objects such as foam inside the shell, the volume of the cleaning plate is increased.

    DETAILED DESCRIPTION In the following, the present invention will be further described with respect to embodiments.
    Embodiment 1 As shown in FIG. 1 to FIG. 8, a cavitation jet cleaning underwater system according to this embodiment comprises a supporting structure 1, an automatic metering device with cleaning solution meter 9 and a flow unit 2, a booster pump 3, a filter 4, a plunger pump 5 and a high pressure hose 6 connected in sequence, where the flow unit 2 supplies power to the booster pump 3 and piston 5. The end of the high-pressure hose 6 with water outlet can be connected to a cleaning gun 7 or a cleaning plate 8 as needed.
    A pipe passage in the course 7-1 of the cleaning gun 7 is formed by connecting a plurality of spherical chambers 7-2, the diameter of the connected portion of two adjacent spherical chambers 7-2 being smaller than the diameter of the spherical chamber 7-2 . The nozzle 7-3 in the tube 7-1 of the cleaning gun 7 is opened with a redirection hole. The redirection hole comprises an inlet passage 7-31 and a vortex segment 7-32, wherein the vortex segment 7-32 is arranged as a spiral passage and the vortex segment is gradually reduced from water inlet to water outlet. Crystallized silica microparticles are dispersed on the surface of the nozzle 7-3, and these silica particles then project from the surface of the nozzle's interior. The silica on the surface of the inside of the nozzle 7-3 can improve the wear resistance and resistance to the high pressure influence of the nozzle, thereby extending the life of the nozzle 7-3 at a high flow rate and under high pressure.
    GB 2019 70456 A1 In this embodiment, the cleaning gun 7 is further equipped with a miniature vibrator 7-6, two plate-shaped conductors, a waterproof gasket 7-4 and a power supply 7-5 for vibration. The waterproof gasket 7-4 can be rotatably installed in the syringe 7-11, with the waterproof gasket 7-4 connected to the syringe 7-11 by thread. In this embodiment, the waterproof gasket 7-4 is part of a rotary switch, the miniature vibrator 7-6 and the power supply 7-5 are installed in the waterproof gasket 7-4. One plate-shaped conductor contacts a negative pole in the power supply 7-5, the other plate-shaped conductor is secured at one end of the waterproof seal 7-
    4. As the watertight gasket 7-6 rotates in a preset direction for shear, the plate-shaped conductor may move with it to finally contact the positive pole of the power supply 7-5. The two plate-shaped conductors are connected to electrodes for the miniature vibrator 7-6. The mechanical vibration from the miniature vibrator 7-6 is used to improve the underwater cavitation effect of the high pressure water flow, further enhancing the cleaning effect. Here, the waterproof gasket 7-4 plays a role both for waterproof sealing and for on / off switching, so that an underwater cleaning operator can manually turn and open or close the miniature vibrator 7-6 as needed. The structure is simple and gives great flexibility. Pipe tube 7-7 is positioned between the syringe and tube 7-1 on the cleaning gun 7. Pipe tube 77 may play a role in buffering to attenuate the miniature vibrator 7-6 vibration to the barrel 7-1. At the same time, one end of the barrel 7-1 near the syringe is equipped with an automatic heating unit 7-10. The automatic heating unit 7-10 consists of a temperature sensor, an electric hotplate, a microchip (not shown in the figure) and a power supply for heating (not shown in the figure). When the water pressure is lower than the preset value, the water is heated in the barrel by means of the electric heating plate to obtain the set temperature so that the preferred cavitation effect is obtained.
    The cleaning plate 8 comprises a hand pressure driven frame 8-1, a shell 8-2, a hollow, revolving shaft 8-3, an input tube 8-4 and a jet tube 8-5. The hand pressure driven frame 8-1 is connected to the shell 8-2. The hollow revolving shaft 8-3 rotatably installed in the shell 8-2. The hollow, rotatable shaft 8-3 is provided with a redirect passage 8-31, and the inside of the redirect passage 8-31 is provided with several arcuate strips 8-32. The lower end of the diversion passage 8-31 is equipped with a syringe 8-33. The high pressure hose 6 is connected to the input tube 8-4, the input tube 8-4 and the jet tube 8-5 are connected to the redirect pass, respectively.
    DK 2019 70456 A1 case 8-31 from the hollow rotating shaft 8-3., Water outlet from the jet tube 8-5 is equipped with a high pressure nozzle 8-51. The high pressure nozzle 8-51 is opened with a redirection hole, and this redirection hole comprises an inlet passage 7-31 and a vortex segment 7-32. The 7-32 diameter of the vortex segment is gradually reduced from water inlet to water outlet, and the inside of the vortex segment 7-32 is equipped with sunken spiral lines. The angle α between the high pressure nozzle 8-51 and the jet tube 8-5 in the horizontal direction is 120 °, 130 °, 150 ° or other, and the angle is adjusted according to the practical situation. The angle β between the high pressure nozzle 8-51 and the jet tube 8-5 in a horizontal direction is 130 °, 150 °, 170 ° or other and the angle is adjusted according to the practical situation. In this embodiment, there are several jet pipes 8-5 for the cleaning plate 8, each pipe equipped with a flow control valve, all flow control valves being controlled by the controller 10. Controlled by the control unit 10, flowing simultaneously by different jet pipes 8-5 at different flow rates. The reactive pressure on each jet tube 8-5 is different, but the cleaning plate 8 moves in different directions to realize the cleaning effect from the automatic movement of the jet jets. In the present embodiment, the shell is also equipped with an ultrasonic generator. Although an ultrasonic cleaner is a commonly used cleaner in places such as laboratories, a conventional ultrasonic cleaner does not require personnel to operate and the items to be cleaned are put in a rinsing tank. However, in underwater cleaning of ships, it is difficult to perform ultrasonic cleaning underwater. An ultrasonic wave is a sound wave with a frequency higher than 20000 Hz. Ultrasonic vibrations can cause movement of substances in a given tissue and alter the internal structure of a cell, resulting in functional alteration of the cell. When the intensity of the ultrasound reaches a certain level, this can cause negative effects on the human body. Thus, the health status of the staff using such a cleaning system for long-term underwater work is affected. Therefore, ultrasound is avoided as often as possible, or ultrasound is eliminated using the apparatus to avoid the adverse effect of known technology on staff health. In the present invention, it is possible to use an ultrasonic generator because the cleaning plate of the present invention does not necessarily have to be manually pushed to move, and the automatic flow and sink movement can be realized by the reactive pressure of multiple jet tubes 8-5 and the hollow, rotating shaft 8-31.
    The lower portion of the hollow, rotating shaft 8-3 is firmly connected to the branch cap 8-6 and the syringe 8-33 is disposed within the branch cap 8-6. One so
    DK 2019 70456 A1 this arrangement has a detrimental effect as the high-speed coil jet, which is ejected from the lower end of the hollow rotating shaft 8-3 and produces an eddy current so that the rotational current and water flow flow back from the ship's surface In this embodiment, the inside of the manifold cap 8-6 is further provided with a plurality of curved plates 8-61 and the plurality of curved plates 8-61 uniformly arranged along a circumferential line. As the branch cap 8-6 rotates with the hollow rotary shaft 8-3, the liquid inside the branch cap 8-6 rotates along the wall to form a double eddy current, the spiral segment being ejected from the lower end of the hollow rotating shaft 8-3. , which leads to the formation of many cavitation cores.
    In this embodiment, a removable lattice network 8-7 is located at the bottom of the cleaning plate 8-2 on the cleaning plate 8 to prevent large external objects from penetrating and damaging the jet tube 8-5, the branch cap 8-6 and the hollow , rotary shaft 8-3.
    The underwater cavitation jet cleaning system further comprises a pressure control system wherein the pressure control system is equipped with multiple transducers used in water pressure testing, a signal transmission line, and several electromagnetic valves. The cleaning gun nozzle and the high pressure nozzle on the cleaning plate are equipped with transducers and electromagnetic valves, respectively, and the transducer and electromagnetic valves are connected via the signal transmission line and the central control unit. The transducer is used to test the water pressure in the nozzle of the cleaning gun and the high pressure nozzle and transmit water pressure signal data to the central control. When the water pressure is lower than the preset value, the central regulator causes the electromagnetic valve to reduce the water outlet to increase the water pressure, but when the water pressure is too high, the central regulator causes the electromagnetic valve to increase the water outlet or mediate the control of the booster pump and the piston pump to prevent damage to the device due to excessive pressure.
    The underwater cavitation jet cleaning system according to this embodiment further comprises an automatic metering device 9 for cleaning solution. The automatic dosing device with meter 9 for cleaning solution is connected to the water outlet of the plunger 5 through an infusion tube, and the infusion tube for the automatic dosing device with meter 9 for cleaning solution
