    The invention relates to a device for installing any probe designed to monitor the pipes of a steam generator, and can be used in steam generators for atomic electrolytes.
    The purpose of the invention is to improve the maneuverability of the device when introducing it into the steam generator.
    At 1, the device is presented, general view, in section; figure 2 is the same, bottom view; in fig.Z - a device with a remote control lock and unlock; Fig. 4 shows the installation of the device in the water chamber of the steam generator.
    The device for mounting the probe holder body opposite the holes of the tube plate in a predetermined breakdown includes a housing consisting of two parts I and 2 installed with the possibility of mutual displacement for a distance not less than the pitch of the placement of the holes 3 in the tube plate 4, each of the parts 1 and 2 bodies are provided with engagement elements 5 in the form of cylinders 6 and 7 placed one in the other, the inner one of which (cylinder 6) is mounted for movement in the direction perpendicular to the tube plate 4, is made at the end with holes 8 and enclosed in the zone of the latter in the shell 9. The device contains two electric motors (not shown), gears 0 and P, fastened to one of the parts of the body and with the corresponding electric motor, a rack 12, mounted on the other part of the body, and a gear wheel 13, placed on the outer cylinder 7 of one of the engagement elements 5 mounted on the same body part as the gears 10 and II with the possibility of the cylinder 7 interacting with the gear 10, and the gear I1 is installed with the possibility of interacting with the gear rack 12. The elements 5 are hooked or can be installed opposite the rows of openings 3 in the tubesheet 4.
    The device can be equipped with a locking latch 14 connected to an additionally installed electric motor 15. The outer cylinder 7 can be made with a groove 16 under the latch 14, which is equipped with a rod 17 and with locking element 18. The latter is made in the form of a ring
    12370932
    mounted with the help of a cable 19. The device is introduced into the water chamber 20 of a steam generator containing pipes 21. A guide tube 22 is attached to the device’s body 5: a guide tube 22 is inserted into which the probe is inserted during control of the pipes 21. The inner cylinder 6 is connected to the flexible 23 hlang
    ten
    which is supplied with gas under pressure.
    Part I of the housing is provided with an opening 24. The inner 6 and outer 7 cylinders form in its lower part a closed chamber 25 connected
    to the gas source. Water to the steam generator chamber 20 is provided with a hatch 26. The unlocking element 18 is provided with a stop 27 for engagement with the latch 1 4.
    In accordance with the invention (; a unit can be inserted into the compartment of the steam generator water chamber 20 by remote control. The unit can be charged
    beyond the holes 3 in the tube plate 4 and move along these holes & 3, thanks to the remote control system. The device is intended to control all the pipes 21 of the steam generator with the aid of a probe on eddy currents introduced through one or several guide pipes 21,
    In order to ensure the fixing device of the proposed device, the shell 9 is pressed against the inner surface of the opening 3 of the tube plate 4 under the action of pressurized gas, for example compressed air, supplied to its inner surface. This gas is supplied through the inner cylinder 6 of the engagement element 5, where it is fed through the flexible hose 23. To move part 2 of the housing relative to part 1 in the latter, an opening 24 is made so that part 2 can move between two half-cords in which the axis of the element 5 the engagement coincides with the axis of one or the other hole 3 in the tube plate 4 located between the engagement elements 5 and the guide tube 22.
    The body part 2 is moved by interacting the gear ID connected to this motor mounted on this part 2 with the toothed rack 12 located on the body part 1. The insertion of the inner cylinder 6 of the engagement element 5 into the openings 3 and its removal from these openings is achieved by supplying pressurized gas to the chamber 25.
    Due to the possibility of the described movements, it is possible to move the guide tube 22 step by step along the row of holes 3 in order to control the tubes constituting this row. If you go from the position shown in FIG. Where the engagement elements 5 are twisted adjacent holes to move to the left, it is enough to release air from the inner cylinder 6 with the chain releasing it from the clutch, take element 5 out of this hole, reducing the pressure in the chamber 25.
    Thereafter, the electric motor is actuated to control the movement of part 2 relative to part 1 in order to set part 2 to the position indicated in (.2. Then, operations similar to those described for 1m are performed in reverse order in order to introduce the element 5 into the adjacent hole and fix this element by applying pressurized gas to the shell 9. The housing part 1, on which the guide tube 22 is mounted, can be moved after the pressure inside the shell 9 is removed and the hook element is removed from the hole STI in which it was recorded.
    In order that the proposed device be able to control all the rows of holes 3 on the tube plate 4, means are provided that allow the part with the guide tube 22 mounted on it to be turned around
    the engagement element 5 mounted on the body part 2.
    This rotation is carried out by raising the outer cylinder 7 of the engagement element 5, mounted on the part 2, by means of the interaction of gear 10 and the gear wheel 13.
    The rotation of the device around the engagement element 5 is disturbed depending on the configuration of the network of holes 3 in the tube plate 4.
    In the case of a configuration in a square-shaped hole 3 (Fig. 2), the magnitude of these rotations is 90 or 180, while in the case of an isosceles-shaped triangle configuration, the magnitude of the rotation is 60, 120 or 180. To provide remote control of the lock-latch 14, mounted in the upper part of the outer cylinder 7, driven by an additionally mounted electric motor 15, which makes the latch 14 rest against the groove 16 on the outer cylinder 7 so as to block the device,
    The unlocking device Dp pulls the cable 19 and thereby moves the unlocking element 18 upwards, which by means of the stop 27 pushes the latch 14 out of the groove 16, overcoming the resistance of the spring 17. The device is inserted into the hatch 26 of the water chamber 20 of the steam generator.
    All work on the proposed ycTpcrficTBa transfer is carried out at a distance and does not require operator intervention inside the steam generator water chamber.
