[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1As shown, a sealing test device for pressure vessels includes a transparent water tank 1. A base 2 is fixedly connected to the lower surface of the transparent water tank 1. A counterweight box 3 is fixedly connected to the lower surface of the middle part of the base 2. A lifting assembly 4 is fixedly connected to the upper surface of the base 2 and is located behind the transparent water tank 1. A material conveying assembly 5 is fixedly connected to the upper surface of the left and right parts of the lifting assembly 4. The outer wall of the front part of the material conveying assembly 5 is movably sleeved with the inner wall of the transparent water tank 1.

[0027] First, the pressure vessel is placed inside the material conveying component 5. Then, through the action of the lifting component 4 and the material conveying component 5, the pressure vessel can be transported to the inside of the transparent water tank 1, which facilitates the loading of materials. Next, the pressure vessel is tested for sealing through the transparent water tank 1.

[0028] like Figure 2 As shown, the outer wall of the support frame 54 is movably connected to the inner wall of the transparent water tank 1. Three arc-shaped support plates 55 are fixedly connected to the upper surface of the support frame 54 and the three arc-shaped support plates 55 are located between four connecting rods 53. A water tank 22 is fixedly connected to the upper surface of the base 2 and the water tank 22 is located between two hydraulic rods 41. The front of the water tank 22 is fixedly connected to the rear of the transparent water tank 1. A handle 24 is fixedly connected to the rear of the water tank 22. A water pump 23 is fixedly connected to the left side of the water tank 22. The front of the water pump 23 is fixedly connected to the rear of the transparent water tank 1. Four casters 21 are fixedly connected to the lower surface of the base 2.

[0029] By pushing the handle 24, the base 2 can move the transparent water tank 1 and water tank 22 to the testing location under the action of the moving wheels 21. Then, through the action of the water pump 23, the water source in the inner cavity of the water tank 22 can enter the interior of the transparent water tank 1, thereby facilitating transportation and movement. The arc-shaped support plate 55 ensures that the pressure vessel can be located in the middle of the inner cavity of the transparent water tank 1 during testing. At the same time, because the transparent water tank 1 is made of transparent material, it is easy for the staff to quickly determine the location of the air leak in the pressure vessel.

[0030] like Figure 3 As shown, the lifting assembly 4 includes two hydraulic rods 41, the lower surfaces of which are fixedly connected to the upper surface of the transparent water tank 1. The output ends of the two hydraulic rods 41 are fixedly connected to a U-shaped support frame 42. The material conveying assembly 5 includes two support columns 51, the opposite rear surfaces of which are fixedly connected to the upper surfaces of the left and right sides of the U-shaped support frame 42. The inner walls of the two support columns 51 are slidably connected to sliding columns 52. The lower surfaces of the front parts of the two sliding columns 52 are fixedly connected to two connecting rods 53. The lower surfaces of the four connecting rods 53 are fixedly connected to a support frame 54.

[0031] The hydraulic rod 41 enables the U-shaped support frame 42 to move the two support columns 51 upward, thereby enabling the support frame 54 to push the three arc-shaped support plates 55 upward. Through the action of the arc-shaped support plates 55, the pressure vessel can be moved out of the inner cavity of the transparent water tank 1, thus facilitating loading and unloading during use.

[0032] like Figure 4 As shown, an arc-shaped protective pad 56 is fixedly connected to the inner wall of the arc-shaped support plate 55. The arc-shaped protective pad 56 is made of elastic rubber.

[0033] The arc-shaped protective pad 56 enables the arc-shaped support plate 55 to provide protection when supporting the pressure vessel.

[0034] A rubber pad 57 is fixedly connected to the lower surface of the support frame 54, and an anti-slip pad is provided on the lower surface of the rubber pad 57.

[0035] The rubber pad 57 provides support and protection for the support frame 54 when it is placed on the ground, thus preventing it from being bumped or knocked.

[0036] like Figure 5 As shown, a hydraulic rod 58 is fixedly connected to the inner cavity of the support column 51, and the output end of the hydraulic rod 58 is fixedly connected to the inner cavity of the sliding column 52.

[0037] The hydraulic rod 58 enables the sliding column 52 to move the pressure vessel back and forth under the action of the support column 51, thereby facilitating material transportation.

[0038] The working principle of this utility model is as follows: First, the pressure vessel is placed inside the three arc-shaped support plates 55. At this time, the arc-shaped protective pads 56 enable the arc-shaped support plates 55 to provide protection when supporting the pressure vessel. Then, the pressure vessel is moved upward above the transparent water tank 1 by the action of the first hydraulic rod 41. Then, the pressure vessel is moved backward to directly above the transparent water tank 1 by the action of the second hydraulic rod 58. Finally, the pressure vessel is placed inside the transparent water tank 1 by the action of the first hydraulic rod 41. Finally, the water source in the inner cavity of the water tank 22 is allowed to enter the transparent water tank 1 by the action of the water pump 23, thereby performing a sealing test on the pressure vessel.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
