[0024] The bottom of the installation box 2 is provided with a shock absorbing assembly 19, which is composed of a shock absorber and a shock absorbing plate. The shock absorber is fixedly installed between the installation box 2 and the shock absorbing plate. The installation of the shock absorber can reduce the damage to the equipment when the device contacts the bottom wall of the container. There are several shock absorbers.

[0025] In this embodiment, the interior of the mounting box 2 is provided with an abutment assembly extending outside thereof, and the abutment assembly includes a servo motor 4 arranged inside the mounting box 2, a mounting plate 6 arranged inside the mounting box 2, a bidirectional screw 5 fixedly installed on the output shaft of the servo motor 4, two moving blocks 7 threadedly connected to the outside of the bidirectional screw 5, and two support rods 8 arranged between the moving blocks 7 and the mounting plate 6, and the two support rods 8 are hinged with hinge seats 9 at one end away from each other, and the hinge seats 9 on the side away from the mounting plate 6 are respectively fixed to the two moving blocks 7, and the two hinge seats 9 close to the side of the mounting plate 6 are slidably connected to the mounting plate 6, and an elastic telescopic frame 10 is fixedly installed on the side of the mounting plate 6 away from the support rod 8, and a pulley 11 is rotatably installed on the end of the elastic telescopic frame 10.

[0026] Among them, a fixing plate 3 is fixedly installed inside the installation box 2, a servo motor 4 is fixedly installed on the upper surface of the fixing plate 3 by bolts, and a bidirectional lead screw 5 passes through the inside of the fixing plate 3 and is connected to the inner bottom wall bearing of the installation box 2.

[0027] Furthermore, the threads on the bidirectional lead screw 5 are opposite to each other, and a movable opening 12 is provided on both the left and right sides of the installation box 2 , through which the four elastic telescopic frames 10 extend to the outside of the installation box 2 .

[0028] It should be noted that the number of support rods 8, elastic telescopic frames 10 and pulleys 11 in the abutment assembly is four, the number of mounting plates 6 is two, and the two mounting plates 6 are symmetrically arranged, and the four elastic telescopic frames 10 are symmetrically installed on the side away from the two mounting plates 6. The number of abutment assemblies is two. The eight pulleys 11 are arranged in groups of four, and two groups of four pulleys 11 are arranged horizontally and vertically.

[0029] In this embodiment, an adjusting mechanism for rotating the installation box 2 is provided on the adjusting box 1; the adjusting mechanism includes an electric push rod 13 fixedly installed on the inner wall of the adjusting box 1, a bow rod 14 rotatably installed inside the adjusting box 1, and a connecting rod 16 arranged inside the adjusting box 1, and one end of the connecting rod 16 away from the bow rod 14 is fixedly connected to a hinge 15 hinged to the output end of the electric push rod 13, and one end of the connecting rod 16 away from the hinge 15 is fixedly installed with a mounting sleeve 17 sleeved with the bow rod 14, and the bottom end of the bow rod 14 is fixed to the upper surface of the installation box 2.

[0030] The bow rod 14 is connected to the internal bearing of the regulating box 1, and the mounting sleeve 17 is located at the arc of the bow rod 14. A wiring hole is provided inside the regulating box 1.

[0031] In addition, two symmetrically distributed limiting rods 18 are fixedly installed on one side of the adjustment box 1 close to the installation box 2. A slide groove adapted to the two limiting rods 18 is provided inside the installation box 2, and the two limiting rods 18 are slidably connected to the two slide grooves respectively. The limiting rods 18 are limited by the slide grooves to ensure that the adjustment mechanism can stably adjust the installation box 2. There is lubricating oil in the slide groove to ensure better sliding of the limiting rods 18.

[0032] The working principle of the above embodiment is:

[0033] When in use, the device is placed into the interior of the pressure vessel through the lifting equipment 23, and the servo motor 4 is started, so that its output shaft drives the bidirectional screw 5 to rotate. Since the threads on the bidirectional screw 5 are opposite, the two moving blocks 7 are separated or approached at this time, so that the pulleys 11 on the left and right sides abut against the inner wall of the pressure vessel, ensuring that the device runs inside the pressure vessel. When it is necessary to rotate the installation box 2, since the pulleys on the two abutting components are arranged horizontally and vertically, it is convenient to cooperate with the adjustment mechanism to rotate and adjust the installation box 2, so as to better observe the inner wall of the cylindrical pressure vessel.
