Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-5, A valve detection device for liquefied gas tank production, including a detection water tank 1. The detection water tank 1 includes three water troughs. On both inner walls of the water troughs on the detection water tank 1, two first guide grooves 2 and second guide grooves 3 are opened. The first guide groove 2 communicates with the second guide groove 3. A placement plate 4 is arranged in the water trough on the detection water tank 1. The placement plate 4 is slidably connected to the detection water tank 1. Four first fixing plates 5 are fixedly connected to the bottom of the placement plate 4. Two first fixing plates 5 at the same end are fixedly connected to the same limiting rod 6. A first sleeve plate 7 is arranged at the bottom of the placement plate 4. The first sleeve plate 7 is sleeved on the limiting rod 6. The first sleeve plate 7 is slidably connected to the limiting rod 6. Sliding rods 8 are fixedly connected to both sides of the first sleeve plate 7. The sliding rods 8 are adapted to the first guide grooves 2 and the second guide grooves 3.

Chute grooves 9 are opened at both ends of the placement plate 4. Sliders 10 are arranged in the chute grooves 9. The sliders 10 are slidably connected to the placement plate 4. Second fixing plates 11 are fixedly connected to the tops of the two sliders 10. Clamping plates 12 are fixedly connected to the sides of the two second fixing plates 11 close to each other. Anti-slip pads are arranged on the inner walls of the clamping plates 12. Due to the technical means of being able to move the two clamping plates while moving the liquefied gas tank, when the liquefied gas tank is lowered, the two clamping plates can be made to approach each other to clamp the liquefied gas tank, and when the liquefied gas tank is raised, the clamping plates can be made to move away from each other and no longer clamp the liquefied gas tank, effectively solving the problem that the existing equipment has cumbersome operation steps. After the liquefied gas tank is placed in the detection water tank, it is also necessary to operate the small hydraulic rod in the limiting mechanism in the detection water tank to make the limiting plate clamp the liquefied gas tank. Each time the liquefied gas tank is placed and taken out, a certain amount of time is required for this operation, which reduces the efficiency of the detection work to a certain extent. Furthermore, the technical effect of simple operation, convenient fixing and releasing of the liquefied gas tank, and improvement of the detection work efficiency is achieved.

[0024] In this embodiment, a plurality of water leakage grooves 13 are opened on the placement plate 4.

[0025] In this embodiment, three drain pipes 14 are fixedly connected to one side of the detection water tank 1. Valves are arranged on the drain pipes 14. The drain pipes 14 communicate with the water troughs.

[0026] In this embodiment, a base 15 is fixedly connected to the bottom of the detection water tank 1.

[0027] In this embodiment, two support rods 16 are fixedly connected to the top of both ends of the base 15. A second sleeve plate 17 is sleeved on the support rod 16, and the second sleeve plate 17 is slidably connected to the support rod 16. The four second sleeve plates 17 are fixedly connected to the same first cross plate 18. Three air extraction pumps 19 are fixedly connected to the top of the first cross plate 18. The input end of the air extraction pump 19 is fixedly connected to an air extraction pipe 20. The air extraction pipe 20 passes through the first cross plate 18 and is fixedly connected to the first cross plate 18. Twelve connecting rods 25 are fixedly connected to the bottom of the first cross plate 18. Four of the twelve connecting rods 25 form a group. The four connecting rods 25 at the same end are fixedly connected to the same placement plate 4.

[0028] In this embodiment, the same second cross plate 21 is fixedly connected to the top of the four support rods 16. A hydraulic push rod 22 is fixedly connected to the top of the second cross plate 21. The output end of the hydraulic push rod 22 is fixedly connected to the first cross plate 18.

[0029] In this embodiment, a sealing strip 23 is fixedly connected to the bottom of the first cross plate 18. A sealing plate 24 is arranged at the bottom of the sealing strip 23. A sealing groove is formed on the sealing plate 24. The sealing strip 23 is adapted to the sealing groove. The sealing plate 24 is fixedly connected to the detection water tank 1.

[0030] Working principle: When using this device, inject water into the water tank of the detection water tank 1, place the liquefied gas tank on the placement plate 4, keep the valve on the liquefied gas tank closed, extend the output end of the hydraulic push rod 22, and the output end of the hydraulic push rod 22 will drive the first cross plate 18 to descend. The first cross plate 18 will drive the second set plate 17 to descend along the support rod 16. When the first cross plate 18 descends, it will not shift. When the first cross plate 18 descends, it will drive the connecting rod 25 to descend, and the connecting rod 25 will drive the placement plate 4 to descend, so that the liquefied gas tank can be lowered and immersed in water. During the descent of the placement plate 4, it will also drive the first fixing plate 5 to descend. The first fixing plate 5 will drive the limiting rod 6 to descend, and the limiting rod 6 will drive the first set plate 7 to descend. The first set plate 7 will drive the sliding rod 8 to move along the first guiding groove 2, and the sliding rods 8 at both ends will move closer to each other. If the sliding rods 8, then the two first set plates 7 will move closer to each other. The two first set plates 7 will drive the two sliders 10 to move. The two sliders 10 move closer to each other, and the sliders 10 drive the second fixing plate 11 to move. The second fixing plate 11 drives the clamping plate 12 to move, and the two clamping plates 12 will move closer to the liquefied gas tank until they contact the liquefied gas tank and clamp the liquefied gas tank, preventing the liquefied gas tank from floating and causing position deviation during water detection, which may affect the test results. When the sliding rod 8 moves into the second guiding groove 3, the clamping plate 12 will clamp the liquefied gas tank. At this time, continuing to lower the placement plate 4 can also enable the sliding rod 8 to move along the second guiding groove 3. When the first cross plate 18 descends, it will also drive the air pump 19, the air extraction pipe 20, and the sealing strip 23 to descend, so that the sealing strip 23 descends until it is inserted into the sealing groove on the sealing plate 24, and the sealing is achieved through the mutual cooperation of the sealing strip 23 and the sealing plate 24. Subsequently, start the air pump 19. The air pump 19 evacuates the inside of the detection water tank 1 to form a negative pressure inside the water tank of the detection water tank 1. Under the action of the pressure difference between the inside and outside of the liquefied gas tank, it is possible to determine the air tightness of the valve of the liquefied gas tank by observing whether bubbles are generated in the water of the detection water tank through the observation window. After the detection is completed, retracting the output end of the hydraulic push rod 22 can raise the first cross plate 18. When the sliding rod 8 moves back into the first guiding groove 2 and continues to rise, the two clamping plates 12 will move away from each other and no longer contact the liquefied gas tank, and the liquefied gas tank that has completed the detection can be removed. Continue the valve detection work according to the same steps.
