Multiple electric valves 43 are connected to an air supply pipe 42.
[0032] The drive mechanism 5 is mounted on the U-shaped mounting frame 1.
[0033] The lifting and maintenance mechanism 2 also includes a movable plate 1 threaded around the reciprocating screw 21. A mounting bracket 24 is fixed to one side of the movable plate 1. A one-way gear 22 is rotatably connected to the outside of the reciprocating screw 21. A guide rod 23 is fixed to the top of the return-shaped mounting frame 1. A movable plate 23 is sleeved around the outside of the guide rod 23. A mounting bracket 26 is fixed to the side of the movable plate 2 near the mounting bracket 24. The mounting bracket 24 and the mounting bracket 26 are symmetrically arranged. A return-shaped plate 25 is fixed to the bottom of the mounting bracket 24 and the mounting bracket 26.
[0034] The sealing mechanism 3 also includes a rotating shaft 31 rotatably connected inside the mounting bracket 24 and the mounting bracket 26. The rotating shaft 31 has multiple sets of reciprocating threads 32 on its outside. Each set of reciprocating threads 32 has two threads. The reciprocating threads 32 are threaded on the outside of the reciprocating threads 32 and a movable plate 33 is fitted on the outside of the movable plate 33. The movable plate 33 is fixedly connected to the U-shaped sealing box 35. A guide rod 34 is fixed between the mounting bracket 24 and the mounting bracket 26. The movable plate 33 is fitted on the outside of the guide rod 34.
[0035] One end of the rotating shaft 31 is fixed with a bevel gear 36, the bottom of the bevel gear 36 is meshed with a bevel gear 38, the inside of the bevel gear 38 is fixed with a rotating shaft 37, the bottom end of the rotating shaft 37 is rotatably connected to the U-shaped mounting frame 1, and a one-way gear 39 is installed on the outside of the rotating shaft 37.
[0036] A detector is fixed to the inner wall of the U-shaped sealed box 35.
[0037] The sealing mechanism 4 includes multiple support plates 41 fixed to the top of the U-shaped plate 25, and an air supply pipe 42 fixed inside the multiple support plates 41. The other end of the air supply pipe 42 is connected to an external air supply pump through a hose.
[0038] The drive mechanism 5 includes a motor 51 fixed to the top of the U-shaped mounting frame 1. A gear 52 is fixed to one end of the output shaft of the motor 51. One side of the gear 52 meshes with a one-way gear 22, and the other side of the gear 52 meshes with a one-way gear 39.
[0039] The motor 51 is electrically connected to a controller, which is electrically connected to the electric valve 43 and the air supply pump.
[0040] Working principle:
[0041] This device is installed on top of the vaporizer, with the U-shaped tube of the vaporizer located between each group of U-shaped sealing boxes 35. The detector acquires gas data around the U-shaped tube to determine its state.
[0042] When a rupture occurs at a certain point in the U-tube, the gas data around the U-tube changes. The controller controls motor 51 to drive gear 52 in reverse. The reverse rotation of gear 52 satisfies the direction of rotation of unidirectional gear 39 driving shaft 37. Shaft 37 drives bevel gear 38 to rotate, which in turn drives shaft 31 to rotate. This causes the moving plate 33 on each set of reciprocating threads 32 to move the U-shaped sealing box 35 closer, sealing the outside of the U-tube and preventing further leakage. When the U-shaped sealing box 35 moves, it causes connector 46 to move and connect with connecting pipe 44. The controller activates the electric valve 43 on one side of the gas detector based on the location of the gas detector and controls the gas supply pump to supply gas to pipe 44. 2. Gas is delivered. Gas is inflated into the airbag 45 through the gas pipe 42 via the electric valve 43 and the connector 46, so that the airbag 45 wraps around the U-shaped tube, thereby blocking the rupture point and preventing leakage. At the same time, the controller alarms, and the maintenance personnel shut off the vaporizer. The gear 52 continues to drive the rotating shaft 31 to rotate, causing the moving plate 33, which moves to the end of the reciprocating thread 32, to move the U-shaped sealing box 35 away. Then, the controller starts the motor 51 to drive the gear 52 to rotate forward, so that the one-way gear 22 drives the reciprocating screw 21 to rotate, causing the moving plate 24, the mounting bracket 26, the return plate 25, the sealing mechanism 3, and the return plate 25 to move upward, exposing the U-shaped tube for easy maintenance.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
