    The invention relates to the field of television monitoring and, in particular, to devices for television monitoring of the inner surface of a cylindrical tank. A device for television monitoring of the inner surface of a cylindrical tank, having a flanged opening for access to the inside, containing a supporting frame, attached to the flange of the hole, transmitting a television camera, a flexible hose, inside of which are placed a cable of power supply and a television signal, at least one projector mounted on the television camera, the tubular bracket to which the television camera is attached, the centering unit and one end of the flexible hose, the second end of which is withdrawn outside of the cylindrical tank 1. However, the known ustroytvo has poor stability of the resulting pattern to be displayed, which is sobby inverted image of the inner surface of the tank, furthermore Ousté) Oystvo does not permit precise casting space defined transmitted portion surface. The aim of the invention is to increase the image stability of the inspected section of a cylindrical tank and to accurately determine its location. The goal is achieved by the fact that in the television monitoring device the inner surface of a cylindrical tank, having a hole with a flange for access to the inside, containing a support frame attached to the flange of the hole, transmitting a television camera, is a flexible hose, inside which are placed power and television cables, at least one searchlight mounted on the transmitting television camera, tubular arm to which the transmitting television camera is attached, the centering unit and the first end A flexible hose, the second end of which is led out to the outside of the cylindrical tank, is fitted with a rigid tubular guide, one end of which is mounted on the supporting frame, a control mechanism with a vertical displacement transducer and an angular displacement transducer of the transmitting television camera, with the second end of the flexible hose inside a rigid tubular guide and brought out through the control mechanism. The centering assembly contains levers, mainly three, three rods, a tubular part with a flange in the upper part, inside of which there is a flexible hose with the possibility of longitudinal movement, with one end of each lever being supplied with fKXinKc Wj and the other hinge bearing with a tubular bracket, Each rod is pivotally connected to a lever by one condom, and the other end is connected to the flange of a tubular part, the second end of which is stiffly tubed, and that guide is provided with hooks to which the control cable attached to the control handle is attached. Located on the outside of the support frame. The flexible hose is made of flexible elastic material and placed in a sheath of corrugated stainless steel. The control mechanism comprises a gear unit, a motor with a gearbox, the shaft of which is connected to the first gear of the gear unit, the second gear which is connected to the first coupling, inside which is a flexible hose, the second coupling connected to the sensor of the transmitting television camera and the eccentric of the blocking movement while the second clutch is rigidly connected to the first clutch, the third gear wheel of the gear unit is connected to the sensor of angular movements of the transmitting television camera, and the third clutch connected to the watches Roy clutch and eccentric blocking niep displacements. The vertical displacement sensor contains a roller that is frictionally connected to a flexible hose, and the angular displacement sensor is made in the form of a cylinder with a scale. FIG. 1 shows a structural diagram of a television monitoring device for the inner surface of a cylindrical tank; FIG. 2 is a structural diagram of the control mechanism in section. The device comprises a cylindrical tank 1, a flange 2, a support frame 3, a tubular arm 5 transmitting the television chamber 4, a flexible hose 6, power supply and television signal cables 7, a projecte 8, a centering unit consisting of levers 9, rods 10, a tubular part 11 with a flange 12, rollers 13, hooks 14, a control cable 15, a control handle 16, a rigid tubular guide 17, a control mechanism 18 comprising a vertical displacement sensor 19 and a transmitting television camera angular displacement sensor 20, gears consisting of first, second and third gears 21-23, motor 24 with gear, first, second and third couplings 25-27, eccentric 28 blocking movements, vertical movement sensor 19 contains roller 2 The device operates as follows .. Transmitting television chamber 4 is inserted inside the cylindrical tank 1 and fixed to flange 2 by means of a support frame. 3. The transmitting television camera 4 is rigidly connected to the tubular arm 5, on which the centering unit is also mounted, which prevents the television camera from changing position in space arbitrarily. Having released the hooks 14 by means of the cable 15 controlling the handle 16, the transmitting television camera is provided with the possibility of vertical movement downwards, for which purpose it is necessary to release the flexible hose 6 by turning the eccentric 28 using, for example, the third clutch 27. The flexible hose 6 begins to slide inside the first and second clutches 25 and 26. The magnitude of the vertical displacements of the television camera is recorded by the sensor 19 of vertical displacements by means of a roller 29 having friction engagement c. flexible hose 6.- Stabilization of the transmitting television camera 4 in space is provided by means of a centering unit having at least three levers 9 with a roller 13 that slide along the walls of the cylindrical tank 1, preventing the transmitting television camera 4 from moving in arbitrary directions . The section of the inner surface of the cylindrical tank 1, inspected by a television camera, is illuminated by a searchlight 8 rigidly fixed on the transmitting television camera 4. There are several such searchlights 8. The rotation of the motor shaft 24 with reduction gear is transmitted to the angular displacement sensor 20, which represents a cylinder with a scale, rigidly fixed on the third gear 23. The second gear 22 through the first clutch 25. Transmits the force from the motor 24 to the flexible hose 6 and, therefore, to the transmitting television chamber 4. Thus, an inspection of the inner surface of the cylindrical tank 1 is carried out at an angle. In order to take out the transmitting television camera 4 from the cylindrical tank 1, raise the transmitting television camera 4 until the tubular part 11 touches the flange 12 with the end of the rigid tubular guide 17, inside which the flexible arm 6 passes. behind the flange 12. By turning the eccentric 28, the flexible hose 6 is released, and the transmitting television camera 4, together with the tubular arm 5, is lowered downwards. The levers 9 rotate in ro and oh 29 under the influence of the rods 10 until they are upright. A passing TV camera 4 can also be timed on a tubular {fbm1Me 5, d, and it will be possible to release 3sa№M 30. n $ extremely tight iobho shmo; if transmitting
    TV camera 4 has dimensions larger than the hole in the tank.
    The proposed device makes it possible to increase the image stability of the inspected section of a cylindrical tank and more accurately determine the location of this section.
