Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically a pressure vessel sealing testing device. Background Technology
[0002] A pressure vessel is a sealed device that holds gas or liquid and withstands a certain pressure. A pressure vessel is a sealed container that can withstand pressure. Before use, a pressure vessel must undergo a sealing test.
[0003] For example, application number CN202122696446.0 discloses a pressure vessel sealing performance testing device, including a transparent box with a drain pipe, a lid at the top, a fixing frame at the bottom, two parallel guide rods on the fixing frame, symmetrical mating blocks slidably connected to the guide rods on both sides, and symmetrical arc-shaped clamps at the bottom of the two mating blocks. A transmission assembly is provided on the lid, and a snap-fit assembly is provided on both the transparent box and the lid. This invention facilitates the testing of the sealing performance of pressure vessels. During use, the lid can be directly placed on the transparent box and pressed down to install it. When removing the lid, the user simply pulls the handle upwards to remove it from the transparent box. This simplifies the installation and removal of the lid, eliminating the need for users to disassemble numerous screws, greatly improving work efficiency and practicality.
[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, although the aforementioned equipment can solve the problem that users need to disassemble and assemble screws every time they open and close the box lid, which is very inconvenient and greatly reduces work efficiency, the clamping device of the aforementioned equipment is integrated with the box lid during use. Therefore, when the clamping device clamps the pressure vessel and puts it into or pulls it out of the transparent box, it bears too much weight. Furthermore, when the clamping device pulls out of the transparent box and clamps the pressure vessel, it requires two or more people to work together, which not only wastes human resources but is also very inconvenient to use. Utility Model Content
[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a pressure vessel sealing detection device, which has the advantage of being easy to use. It solves the problems of the above-mentioned devices where the clamping device is integrated with the box cover, resulting in excessive weight when the clamping device holds the pressure vessel and puts it into or pulls it out of the transparent box. Furthermore, when the clamping device is pulled out of the transparent box and clamps the pressure vessel, it requires two or more people to operate simultaneously, which not only wastes human resources but is also very inconvenient to use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel sealing detection device, comprising a transparent box, a box cover, a clamping device, and a clamping plate. The bottom of the box cover is movably connected to the top of the transparent box, the top of the clamping device is fixedly connected to the bottom of the box cover, the top of the clamping plate is fixedly connected to both sides of the bottom of the clamping device, a mounting plate is fixedly connected to the back of the transparent box, a motor is fixedly connected to the top of the mounting plate, a screw is fixedly connected to the output end of the motor, a lifting block is threaded onto the surface of the screw, the front of the lifting block is fixedly connected to the back of the box cover, a placement component is provided at the bottom of the clamping plate, and limit components are fixedly connected to the top of both sides of the transparent box.
[0007] As a preferred embodiment of this utility model, the placement component includes a trapezoidal groove, which is formed at the bottom of the clamping plate. A trapezoidal plate is provided inside the transparent box, and the two ends of the surface of the trapezoidal plate are slidably connected to the inner wall of the trapezoidal groove.
[0008] As a preferred embodiment of this utility model, the limiting component includes a vertical rod, the bottom of the inner side of the vertical rod is fixedly connected to the top of both sides of the transparent box, and a limiting block is sleeved on the surface of the vertical rod, the inner side of the limiting block is fixedly connected to both sides of the box cover.
[0009] As a preferred embodiment of this utility model, each of the four corners of the top of the trapezoidal plate is fixedly connected to a fixing plate, and the top of the fixing plate is fixedly connected to the bottom of the box cover.
[0010] As a preferred embodiment of this invention, a linear bearing is fixedly connected to the inner wall of the limiting block, and the inner wall of the linear bearing is movably connected to the surface of the upright.
[0011] As a preferred embodiment of this utility model, a U-shaped frame is fixedly connected to the top of the mounting plate, and the top of the screw is movably connected to the top of the inner wall of the U-shaped frame via a pivot pin.
[0012] As a preferred embodiment of this utility model, the top of the trapezoidal plate is provided with a through hole, and the through holes are provided in a plurality of them and are distributed in a rectangular and equidistant manner.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by incorporating a motor and screw, allows for easy operation when a pressure vessel needs sealing testing. The motor is activated, driving the screw to rotate, which in turn moves the lifting block and lifts the lid, pulling the clamping device and clamping plate out of the chamber. The placement assembly then provides support for the pressure vessel. The clamping device is then activated again, causing the clamping plate to hold the pressure vessel. Reversing the motor resets the lid, allowing the pressure vessel to be submerged in water for testing. This solves the problems of the previous devices where the clamping device and lid were integrated, resulting in excessive weight-bearing when the device held the pressure vessel and placed or removed from the transparent chamber. Furthermore, removing the device from the transparent chamber and clamping the pressure vessel required two or more people working simultaneously, wasting manpower and being inconvenient to use. This invention achieves a user-friendly solution.
[0015] 2. This utility model, through the setting of a placement component, allows the user to start the motor, drive the screw to rotate, and cause the lifting block to lift the box cover. After the clamping device and clamping plate are pulled out of the transparent box, when it is necessary for the clamping plate to clamp the pressure vessel, the pressure vessel is first placed on the trapezoidal plate, using the trapezoidal plate as a platform. Then, the clamping device is started to drive the two clamping plates to move symmetrically. Subsequently, under the sliding cooperation between the trapezoidal groove and the trapezoidal plate, the clamping plate finally clamps the pressure vessel, thus allowing the user to complete the clamping of the pressure vessel with only one person, thereby improving the user's work efficiency.
[0016] 3. This utility model, by setting a limiting component, ensures that when the motor drives the screw to rotate, causing the lifting block to raise or lower the lid, and during the process of pulling out or placing the clamping device and clamping plate into the transparent box, the limiting block will move along the trajectory of the upright along with the lifting of the lid. Thus, through the cooperation of the limiting block and the upright, the lifting trajectory of the lid is limited, thereby preventing the lid from wobbling left and right due to the screw drive and failing to lift normally, which would prevent the clamping device and clamping plate from being smoothly inserted into the transparent box, thereby improving the stability of the lid during lifting.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the pressure vessel sealing detection device provided by this utility model includes a transparent box 1, a box cover 2, a clamping device 3, and a clamping plate 4. The bottom of the box cover 2 is movably connected to the top of the transparent box 1. The top of the clamping device 3 is fixedly connected to the bottom of the box cover 2. The top of the clamping plate 4 is fixedly connected to both sides of the bottom of the clamping device 3. A mounting plate 5 is fixedly connected to the back of the transparent box 1. A motor 6 is fixedly connected to the top of the mounting plate 5. A screw 7 is fixedly connected to the output end of the motor 6. A lifting block 8 is threadedly connected to the surface of the screw 7. The front of the lifting block 8 is fixedly connected to the back of the box cover 2. A placement component 9 is provided at the bottom of the clamping plate 4. Limiting components 10 are fixedly connected to the top of both sides of the transparent box 1.
[0023] refer to Figure 2 and Figure 3 The placement component 9 includes a trapezoidal groove 91, which is opened at the bottom of the clamping plate 4. A trapezoidal plate 92 is provided inside the transparent box 1, and the two ends of the surface of the trapezoidal plate 92 are slidably connected to the inner wall of the trapezoidal groove 91.
[0024] As a technical optimization of this utility model, by setting up the placement component 9, when the user starts the motor 6, the screw 7 is driven to rotate, causing the lifting block 8 to lift the box cover 2. After the clamping device 3 and the clamping plate 4 are pulled out of the transparent box 1, when it is necessary for the clamping plate 4 to clamp the pressure vessel, the pressure vessel is first placed on the trapezoidal plate 92, using the trapezoidal plate 92 as a platform. Then, the clamping device 3 is started to drive the two clamping plates 4 to move symmetrically. Subsequently, under the sliding cooperation of the trapezoidal groove 91 and the trapezoidal plate 92, the clamping plate 4 finally clamps the pressure vessel, thus allowing the user to complete the clamping of the pressure vessel with only one person, thereby improving the user's work efficiency.
[0025] refer to Figure 1 and Figure 3The limiting component 10 includes a pole 101, the bottom of the inner side of the pole 101 is fixedly connected to the top of both sides of the transparent box 1, and a limiting block 102 is sleeved on the surface of the pole 101, and the inner side of the limiting block 102 is fixedly connected to both sides of the box cover 2.
[0026] As a technical optimization of this utility model, by setting a limiting component 10, when the motor 6 drives the screw 7 to rotate, causing the lifting block 8 to drive the box cover 2 to rise or fall, during the process of pulling out or putting the clamping device 3 and clamping plate 4 into the transparent box 1, the limiting block 102 will move along the trajectory of the upright 101 together with the rise and fall of the box cover 2. Thus, through the cooperation of the limiting block 102 and the upright 101, the rising and falling trajectory of the box cover 2 is limited, thereby preventing the box cover 2 from swaying left and right due to the drive of the screw 7 and failing to rise and fall normally, which would prevent the clamping device 3 and clamping plate 4 from being inserted smoothly into the transparent box 1, thereby improving the stability of the box cover 2 when rising and falling.
[0027] refer to Figure 2 Each of the four corners of the top of the trapezoidal plate 92 is fixedly connected to a fixing plate 11, and the top of the fixing plate 11 is fixedly connected to the bottom of the box cover 2.
[0028] As a technical optimization of this utility model, by setting a fixing plate 11, a connection is established between the trapezoidal plate 92 and the box cover 2, and then the clamping device 3 drives the two clamping plates 4 to move symmetrically, so that when the trapezoidal groove 91 slides along the trajectory of the trapezoidal plate 92, the trapezoidal plate 92 always remains stable and cannot move left or right, thus preventing it from deviating out of the area of the inner wall of the transparent box 1 and causing the box cover 2 to be blocked when it falls, so that the clamping plate 4 and the clamping device 3 can enter the transparent box 1.
[0029] refer to Figure 3 The inner wall of the limiting block 102 is fixedly connected to a linear bearing 12, and the inner wall of the linear bearing 12 is movably connected to the surface of the upright 101.
[0030] As a technical optimization of this utility model, by setting a linear bearing 12, when the limiting block 102 slides along the trajectory of the upright 101 together with the lifting and lowering of the box cover 2, the linear bearing 12 inside the limiting block 102 will replace its inner wall to contact the surface of the upright 101, thereby reducing the contact surface between the limiting block 102 and the upright 101, reducing friction and wear, and thus improving the service life of the upright 101 and the limiting block 102.
[0031] refer to Figure 1 and Figure 2 The top of the mounting plate 5 is fixedly connected to the U-shaped frame 13, and the top of the screw 7 is movably connected to the top of the inner wall of the U-shaped frame 13 through a shaft pin.
[0032] As a technical optimization of this utility model, by setting up the U-shaped frame 13, a support point is provided for the other end of the screw 7, thereby improving the stability of the screw 7 when it is driven by the motor 6 and rotates. This prevents the screw 7 from tilting and bending due to excessive pressure when the screw 7 drives the lifting block 8 to lift the box cover 2 and pull out the clamping plate 4 and clamping device 3 from the transparent box 1, thus improving the service life of the screw 7.
[0033] refer to Figure 3 The top of the trapezoidal plate 92 has a through hole 14, and there are several through holes 14 distributed in a rectangular and equidistant manner.
[0034] As a technical optimization of this utility model, by setting through hole 14, when the trapezoidal plate 92 is pulled out from the water-filled transparent box 1, water will pass through through hole 14, thereby reducing the amount of water that the trapezoidal plate 92 can carry, thus preventing water waste caused by surface tension when the trapezoidal plate 92 is pulled out of the water.
[0035] The working principle and usage process of this utility model are as follows: When the user needs to perform a sealing test on a pressure vessel, first start the motor 6 to drive the screw 7 to rotate, causing the lifting block 8 to lift the cover 2. At the same time, the limiting block 102 moves along the trajectory of the vertical rod 101 with the lifting of the cover 2. Subsequently, through the cooperation of the limiting block 102 and the vertical rod 101, the lifting trajectory of the cover 2 is limited. Then, the clamping device 3, clamping plate 4, and trapezoidal plate 92 are stably pulled out of the transparent box 1. Water can then be injected into the transparent box 1, and then the pressure vessel to be tested can be placed inside. On the trapezoidal plate 92, the clamping device 3 can be activated, driving the two clamping plates 4 to move symmetrically inward. Then the trapezoidal groove 91 begins to move along the trajectory of the trapezoidal plate 92 until the clamping plates 4 clamp the pressure vessel on the trapezoidal plate 92. Finally, the motor 6 can be activated in reverse to drive the screw 7 to reverse, thereby causing the lifting block 8 and the box cover 2 to descend and reset, so that the clamping device 3, the clamping plates 4 and the trapezoidal plate 92 are submerged in the water in the transparent box 1 until the pressure vessel is completely submerged in water. At this time, the sealing of the pressure vessel can be judged by observing whether bubbles are generated in the water, thus having the advantage of being easy to use.
[0036] In summary, this pressure vessel sealing test device, by incorporating a motor 6 and a screw 7, allows for sealing tests on pressure vessels. When the pressure vessel needs to be tested, the motor 6 is activated, driving the screw 7 to rotate, which in turn moves the lifting block 8 and causes the lid 2 to move upwards. This allows the clamping device 3 and clamping plate 4 to be pulled out of the housing. The placement assembly 9 then provides support for the pressure vessel. The clamping device 3 is then activated again, causing the clamping plate 4 to clamp the pressure vessel. Finally, the reverse rotation of the motor 6 resets the lid 2, allowing the pressure vessel to be immersed in water for testing. This solution addresses the problems of the previous devices where the clamping device and lid were integrated, resulting in excessive weight-bearing when the clamping device held the pressure vessel and placed or removed from the transparent housing. Furthermore, when the clamping device was removed from the transparent housing and held the pressure vessel, it required two or more people to operate simultaneously, wasting manpower and being inconvenient to use.
