[0003] In the existing sealing detection devices for gas cylinders, it is usually necessary to maintain the stability of the gas cylinders during the detection of gas cylinders, and the gas cylinders will be reinforced. Most of the existing detection devices need to manually or mechanically reinforce the gas cylinders separately, resulting in a relatively complex structure of the detection device, poor operability, and easy to affect the sealing detection of the gas cylinders by the detection equipment. At the same time, most of the existing detection devices can only judge whether the sealing performance of the gas cylinders is good, but it is not convenient to determine the specific leakage position of the gas cylinders, and additional inspections are required, reducing the detection efficiency.

[0004] Therefore, we provide a sealing detection device for gas cylinders to solve the above problems. Content of the Utility Model

Through the combined setting of the sealing component and the detection component, it solves the problems that the operation of fixing the position of the gas cylinder in the existing sealing detection device for gas cylinders is relatively cumbersome and it is not convenient to determine the specific leakage position of the gas cylinder.

[0013] The present utility model is further provided that one side of the bottom of the cross plate is fixedly connected with a right-angle frame, and a control panel is fixedly connected to one side of the right-angle frame.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Specific Embodiment 1

[0030] Please refer to Figures 1-5 , the present utility model is a sealing detection device for gas cylinders, including a chassis 1, a column 2 is arranged on one side of the top of the chassis 1, and a detection tank 3 is fixedly connected to the top of the chassis 1;

[0031] A sealing component is arranged on one side of the surface of the column 2. The sealing component includes a cross plate 4, the cross plate 4 is fixed to the top of the surface of the column 2, one side of the bottom of the cross plate 4 is fixedly connected with a telescopic rod 5, a spring 6 is sleeved on one side of the surface of the telescopic rod 5, one end of the telescopic rod 5 is fixedly connected with a fixed disk 7, and a sealing member is arranged at the bottom of the fixed disk 7;

[0032] A detection component is arranged in the inner cavity of the detection tank 3. The detection component includes a gas cylinder body 8, the gas cylinder body 8 is arranged in the inner cavity of the detection tank 3, one side of the bottom of the detection tank 3 is communicated with a water pump 9 through a water pipe, the output end of the water pump 9 is communicated with a water delivery pipe 10, and gas detectors 11 are fixedly connected to the four sides of the inner cavity of the detection tank 3.

[0033] Specifically: The column 2 is fixed on the left side of the top of the chassis 1, the detection tank 3 is fixed on the top of the chassis 1, both sides of the top of the fixed disk 7 are respectively fixed to one end of the two telescopic rods 5, and a spring 6 is sleeved on one side of the surface of each telescopic rod 5. The spring 6 can squeeze the position of the fixed disk 7, so as to limit the position of the gas cylinder body 8 during detection. During detection, the bottle mouth of the gas cylinder body 8 is closely attached to the inner cavity of the sealing plug 13. The water pump 9 can pump the water outside to facilitate the detection of air tightness, and can also pump the water in the detection tank 3 out. Because water has buoyancy, when the detection tank 3 is full of water, it is not convenient to place the gas cylinder inside. Other detectors are completed by electrochemical sensors. This kind of sensor is based on the principle of redox reaction. When the gas cylinder leaks, the leaked gas will react with the electrodes inside the electrochemical sensor. This reaction will generate a current change. The sensor will detect the change and convert it into an electrical signal. By measuring the magnitude of the current change, the concentration of the leaked gas and the leakage position can be determined. Specific Embodiment 2

[0035] Please refer to Figures 1-5, on the basis of Specific Embodiment 1, the seal includes a threaded sleeve 12. The threaded sleeve 12 is fixed to the bottom of the fixed disk 7. A sealing plug 13 is fixedly connected to the bottom end of the threaded sleeve 12. An extrusion disk 14 is threadedly connected to the surface of the threaded sleeve 12. One side of the top of the cross plate 4 is fixedly connected with an air pump 15 through a limiting block. The output end of the air pump 15 is communicated with an air delivery pipe 16. One end of the air delivery pipe 16 extends to the bottom of the sealing plug 13. One end of the air delivery pipe 16 is fixedly connected with an air outlet head. One side of the top of the chassis 1 is fixedly connected with an arc-shaped frame 17. One side of the bottom of the inner cavity of the arc-shaped frame 17 is fixedly connected with a motor 18. The output end of the motor 18 is fixedly connected with a first gear 19. One side of the surface of the column 2 is fixedly connected with a second gear 20. The second gear 20 meshes with the first gear 19.

[0036] Specifically: The inner cavity of the threaded sleeve 12 is empty to facilitate the extension of the surface of the air delivery pipe 16 out of the sealing plug 13. The sealing plug 13 seals the bottle mouth of the gas cylinder body 8. The extrusion disk 14 can move on the surface of the threaded sleeve 12 to squeeze the sealing plug 13, so that the sealing plug 13 is sealed with the bottle mouth. The air delivery pipe 16 is a flexible pipe because the air outlet head at the bottom end of the air delivery pipe 16 will move up and down. The surface of the air delivery pipe 16 contacts and fits with the inner cavity of the cross plate 4, the inner cavity of the fixed disk 7, and the inner cavity of the threaded sleeve 12. The alarm can transmit the electrical signal generated by the alarm of the gas detector 11. The surface of the gas detector 11 that detects leakage will emit red light. There are four gas detectors 11 in total. The second gear 20 is fixed to the top of the surface of the column 2, and the teeth mesh with the teeth of the first gear 19. Specific Embodiment 3

[0038] Please refer to Figures 1-5 , on the basis of Specific Embodiment 1 and Specific Embodiment 2, a right-angle frame is fixedly connected to one side of the bottom of the cross plate 4. A control panel 21 is fixedly connected to one side of the right-angle frame. A round hole is opened in the inner cavity of the fixed disk 7. The inner cavity of the round hole extends to the outside of the sealing plug 13. The surface of the air delivery pipe 16 extends to the outside of the sealing plug 13 through the inner cavity of the round hole. A placement groove is opened in the inner cavity of the detection tank 3. One side of the surface of the gas cylinder body 8 is slidably connected to the inner cavity of the placement groove. An alarm 22 is fixedly connected to one side of the top of the cross plate 4. The input end of the alarm 22 is unidirectionally electrically connected to the output end of the gas detector 11.

[0039] Specifically: The right-angle frame supports the control panel 21. One side of the bottom of the control panel 21 is fixed to one end of the right-angle frame, and one side of the top is fixed to one side of the cross plate 4. The control panel 21 can control the air pump 15 and the water pump 9 to work, and can also display the data detected by the gas detector 11. The outer wall of one side of the surface of the air delivery pipe 16 is fixed to the inner cavity of the round hole to prevent air leakage from the round hole. The bottom end of the round hole is fixedly sealed with one end of the air outlet head. The inner cavity of the placement groove can limit the bottom end of the surface of the gas cylinder body 8. One side of the inner cavity of the cross plate 4 contacts one side of the surface of the column 2. The reinforcing ring can make the cross plate 4 more stable.

[0040] The working principle of the present utility model is as follows: When it is necessary to conduct a sealing test on the gas cylinder, first start the motor 18. The motor 18 drives the first gear 19 to rotate when it works. The first gear 19 drives the second gear 20 to rotate, and the second gear 20 drives the column 2 to rotate, so that the cross plate 4 moves out of the detection tank 3. Then place the gas cylinder body 8 in the placement groove of the detection tank 3, pull the fixed disk 7 upward, and reverse the motor 18 again. The motor 18 moves the cross plate 4 reversely to align the sealing plug 13 at the inner bottom of the detection tank 3 with the bottle mouth, and makes the bottom of the inner cavity of the sealing plug 13 fit with the bottle mouth, so that the spring 6 and the telescopic rod 5 cooperate to make the gas cylinder in a stable state. Then turn the extrusion disk 14 on the surface of the threaded sleeve 12. The extrusion disk 14 moves to squeeze the sealing plug 13, so that the sealing plug 13 fits tightly with the bottle mouth, producing a sealing effect on it;

[0041] Then conduct a sealing test on the gas cylinder body 8. First, pump the water from the outside into the detection tank 3 through the water pump 9 via the water delivery pipe 10, so that the highest point of the water contacts the top of the bottle mouth. At this time, the spring 6 squeezes the gas cylinder so that it can reduce the buoyancy effect of the water, enabling the gas cylinder to be stably placed in the detection tank 3. Then turn on the air pump 15 through the control panel 21. The air pump 15 works to send gas into the gas cylinder body 8 through the air delivery pipe 16. When there is other leakage inside the gas cylinder body 8, water bubbles can be found by observation, so as to judge that there is a problem with the sealing performance of the gas cylinder body 8. Then use other detectors to detect the leakage point. The gas detector 11 close to the leakage point among the four gas detectors 11 will transmit a signal to the alarm 22 to give an alarm, and the gas detector 11 will also emit red light to facilitate the staff to judge the specific position.
