[0029] Refer to Figures 1-6, A non-destructive testing device for compressed natural gas storage wells, including a support plate 1: On the upper surface of the support plate 1, a first fixed plate 2 and a second fixed plate 3 are symmetrically and fixedly connected. On the lower side of the first fixed plate 2 and the second fixed plate 3, there is a clamping and fixing mechanism 4. The clamping and fixing mechanism 4 includes a positive and negative screw rod 401 rotatably connected to one side of the first fixed plate 2. The positive and negative screw rod 401 passes through the first fixed plate 2 and the second fixed plate 3 and is rotatably connected to the first fixed plate 2 and the second fixed plate 3. On the outer surface of the positive and negative screw rod 401, a first clamping plate 402 and a second clamping plate 403 are symmetrically threadedly connected. On the upper surface of the first fixed plate 2, a connecting frame 5 is fixedly connected, and the other end of the connecting frame 5 is fixedly connected to the upper surface of the second fixed plate 3. On the upper side wall of the first fixed plate 2, a first motor 6 is fixedly connected. The output end of the first motor 6 is fixedly connected to a lead screw 7. On the outer surface of the lead screw 7, a moving sleeve 8 is rotatably connected. On the outer surface of the moving sleeve 8, a turntable 9 is rotatably connected. A rope 10 is wound around the outer surface of the turntable 9. The lower surface of the rope 10 is fixedly connected to a detection mechanism 11. On one side of the positive and negative screw rod 401, a turning knob 12 is fixedly connected. On the outer surface of the turntable 9, a runner 25 is fixedly connected. The detection mechanism 11 includes a cylinder body 1101 fixedly connected to one end of the rope 10. On the upper surface of the cylinder body 1101, an annular light belt 1102 is fixedly connected. On the upper inner wall of the cylinder body 1101, a data collector 1103 is fixedly connected. On the lower side wall of the cylinder body 1101, an ultrasonic detector 1104 is fixedly connected. The lower surface of the ultrasonic detector 1104 is electrically connected to a detection probe 1105. On one side of the lower surface of the cylinder body 1101, a connecting plate 13 is fixedly connected. On one side of the connecting plate 13, a box body 14 is fixedly connected. Inside the box body 14, a second motor 15 is fixedly connected. The output end of the second motor 15 is fixedly connected to a rotating shaft 16. On the outer surface of the rotating shaft 16, a connecting sleeve 17 is fixedly connected. One side of the connecting sleeve 17 is fixedly connected to the detection probe 1105. In the middle of the upper surface of the connecting frame 5, a groove body 18 is fixedly connected. On the inner bottom wall of the groove body 18, a controller 19 is fixedly connected.The controller 19 is electrically connected to the first motor 6, the second motor 15, the data collector 1103, the annular light strip 1102, and the ultrasonic detector 1104. The controller 19, the first motor 6, the second motor 15, the data collector 1103, the annular light strip 1102, and the ultrasonic detector 1104 are all built-in with storage batteries. When non-destructive testing of the gas storage well is required, turning the knob 12 drives the positive and negative screw rod 401 to rotate. The rotation of the positive and negative screw rod 401 drives the first clamping plate 402 and the second clamping plate 403 to move towards each other on its outer surface, so as to firmly fix the device on the outer wall of the gas storage well for use. Driven by the controller 19, the first motor 6 drives the first motor 6 to rotate, and the rotation of the first motor 6 drives the moving sleeve 8 to move horizontally on its outer surface through the lead screw 7, so as to adjust the position of the detection probe 1105. After adjusting to the appropriate position, turning the runner 25 drives the turntable 9 to rotate, so as to put the rope 10 into the gas storage well and lower the rope. The annular light strip 1102, the data collector 1103, and the ultrasonic detector 1104 clearly transmit the image inside the gas storage well to the controller 19. Then, the controller 19 drives the second motor 15 and adjusts the angle of the detection probe 1105 through the rotating shaft 16 and the connecting sleeve 17. Thus, the position and angle of the detection probe 1105 can be remotely adjusted through the rope 10, the first motor 6, the lead screw 7, the second motor 15, and the connecting sleeve 17, so as to perform non-destructive testing on the gas storage well. Compared with the winch control detection method, this device is smaller in volume and more convenient to carry, thus saving labor costs and equipment costs.

[0030] A through groove 20 is opened on one side wall of the tank body 18. A cover plate 21 is slidably connected to the inner wall of the through groove 20. The size of the cover plate 21 is adapted to that of the through groove 20. Sliding grooves 22 are opened on both side walls of the tank body 18. Sliders 23 are slidably connected to the inner walls of the sliding grooves 22. The sliders 23 are fixedly connected to the cover plate 21. A push plate 24 is fixedly connected to one side of the upper surface of the cover plate 21. The controller 19 can be protected by the cover plate 21 and the tank body 18, so as to prevent the controller 19 from being exposed and dust accumulating on its surface, which affects its use.

[0031] Working principle: When nondestructive testing of the gas storage well is required, turn the knob 12 to drive the left and right screw rod 401 to rotate. The rotation of the left and right screw rod 401 drives the first clamping plate 402 and the second clamping plate 403 to move towards each other on its outer surface, so as to firmly fix the device on the outer wall of the gas storage well for use. Driven by the controller 19, the first motor 6 rotates. The rotation of the first motor 6 drives the moving sleeve 8 to move horizontally on its outer surface through the lead screw 7, so as to adjust the position of the detection probe 1105. After adjusting to the appropriate position, rotate the runner 25 to drive the turntable 9 to rotate, so as to put the rope 10 into the gas storage well and lower the rope. The internal image of the gas storage well is clearly transmitted to the controller 19 through the annular light belt 1102, the data collector 1103 and the ultrasonic detector 1104. Then, the controller 19 drives the second motor 15, and adjusts the angle of the detection probe 1105 through the rotating shaft 16 and the connecting sleeve 17. Therefore, the position and angle of the detection probe 1105 can be remotely adjusted through the rope 10, the first motor 6, the lead screw 7, the second motor 15 and the connecting sleeve 17, so as to perform nondestructive testing on the gas storage well. Compared with the way of controlling the detection by a winch, this device is smaller in volume and more convenient to carry, thus saving labor costs and equipment costs.
