Technical Field
[0001] This utility model relates to the field of cylinder drainage technology, specifically a cylinder water pressure test drainage device. Background Technology
[0002] Gas cylinders are steel containers used to store high-pressure oxygen, carbon dioxide, acetylene, liquefied petroleum gas, and other gases. As commonly used pressure vessels, gas cylinders are widely used in daily life and industrial production due to their high toughness and pressure-bearing capacity. Gas cylinders play a vital role in both daily life and industrial production. To ensure their stability and safety during use, a hydrostatic test is usually required. The hydrostatic test is a gas cylinder inspection procedure, primarily aimed at verifying whether the overall strength of the cylinder meets requirements and assessing its pressure-bearing capacity, thus exposing potential defects. During the hydrostatic test, water is typically injected into the cylinder, and after the test, the water needs to be drained. Currently, after the hydrostatic test, the cylinder is usually pushed to a drainage pool using an auxiliary trolley, and then manually laid down to drain the water. This process is time-consuming, labor-intensive, and poses a certain degree of danger due to the manual handling of a water-filled cylinder. Therefore, there is a need to develop a convenient, time-saving, and labor-saving hydrostatic test drainage device for gas cylinders. Utility Model Content
[0003] To address the above technical problems, this utility model provides a convenient and time-saving drainage device for gas cylinder water pressure testing, which solves the problem of time-consuming and labor-intensive drainage of gas cylinders after water pressure testing.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1 , 2A cylinder water pressure test drainage device shown in Figure 3 includes a base plate 1, with a movable wheel 10 connected to the lower end of the base plate 1. Support frames 2 are fixedly connected to the front and rear sides of the base plate 1, and a placement groove 3 is rotatably connected to the support frames 2. Rotating shafts are fixedly connected to the front and rear sides of the middle of the placement groove 3, and the rotating shafts are rotatably connected to the corresponding support frames 3 through bearings. A telescopic rod 4 is rotatably connected to one side of the base plate 1 through a connecting frame and a hinge shaft. The output end of the telescopic rod 4 is rotatably connected to the connecting lug at the bottom of the placement groove 3. A shovel plate 5 is fixedly connected to one end of the placement groove 3, and a baffle 14 is fixedly connected to the other end. A groove 15 is provided in the middle of the baffle 14 to allow the valve at the top of the cylinder to pass through. At least one arc-shaped plate 6 is rotatably connected to one side of the upper end of the placement groove 3, and the other end of the arc-shaped plate 6 is detachably connected to the other side of the placement groove 3. A water receiving tank 7 is fixedly connected to one end of the base plate 1, and the water receiving tank 7 is located on the side of the placement groove 3 connected to the baffle 14.
[0018] It should be noted that, in this embodiment, the moving wheels 10 are universal wheels to facilitate the movement of the device; a trolley handle is fixedly connected to one end of the base plate 1 to facilitate pushing the device; to simplify the structure and facilitate use, the telescopic rod 4 is an electric telescopic rod. At the same time, the telescopic rod 4 can also be a hydraulic telescopic rod or a pneumatic telescopic rod. When a hydraulic telescopic rod or a pneumatic telescopic rod is used, the device is equipped with a corresponding pressure supply component; in this embodiment, there are two arc-shaped plates 6.
[0019] To prevent the gas cylinder from sliding and damaging the baffle 14 when the placement slot 3 rotates, a buffer plate 16 is slidably connected inside the placement slot 3. The buffer plate 16 is set parallel to the baffle 14. A groove 15 is opened in the middle of the buffer plate 16. The groove 15 on the buffer plate 16 corresponds to the groove 15 on the baffle 14. A spring 19 is fixedly connected between the buffer plate 16 and the baffle 14.
[0020] To ensure the position of the buffer plate 16 when it slides, a guide rod 17 is fixedly connected to the inner side of the baffle 14, and a guide sleeve 18 is fixedly connected to one side of the buffer plate 16. One end of the guide rod 17 is slidably connected to the guide sleeve 18, and a spring 19 is sleeved on the guide rod 17 and the guide sleeve 18. The two ends of the spring 19 are fixedly connected to the buffer plate 16 and the baffle 14 respectively.
[0021] To facilitate the drainage of water from the water tank 7, a drain pipe 8 is fixedly connected to the lower end of the water tank 7, and a drain valve 9 is fixedly connected to the drain pipe 8. It should be noted that in this embodiment, the bottom of the water tank 7 is inclined downwards towards the drain pipe 8, and a pipe joint is connected to the lower end of the drain pipe 8, which can be quickly connected to the drain pipe when draining water.
[0022] To improve work efficiency, one end of the arc plate 6 is hinged to one side of the placement groove 3, and the other side of the placement groove 3 is fixedly connected to a pin ring 12. The pin 13 passes through the pin ring 12 and the through hole opened at the other end of the arc plate 6.
[0023] To improve the stability and robustness of the device, reinforcing ribs 11 are fixedly connected between the shovel plate 5 and the placement trough 3, and between the water tank 7 and the base plate 1.
[0024] The working process of this embodiment is as follows:
[0025] After the cylinder undergoes a water pressure test, push the device to the cylinder and extend the telescopic rod 4 to make the shovel plate 5 contact the ground. Use the shovel plate 5 to move the cylinder into the placement groove 3. Then close the arc plate 6 and use the pin 13 to pass through the pin ring 12 and the through hole at the other end of the arc plate 6. Set a safety pin at the end of the pin 13. Then retract the telescopic rod 4. At this time, the telescopic rod 4 drives the placement groove 3 to rotate, causing the upper end of the cylinder to tilt downward. The cylinder slides in the placement groove 3 and contacts the buffer plate 16. Under the action of the spring 19, guide rod 17 and guide sleeve 18, damage to the baffle 14 is avoided. At this time, the cylinder valve passes through the groove of the buffer plate 16 and the baffle 14 and is located directly above the water receiving tank 7. Open the cylinder valve to drain water and let the water enter the water receiving tank 7. Connect the drain pipe to the drain pipe 8 in advance and open the drain valve 9 to drain water.
