Description

Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas (LPG) cylinder air tightness testing technology, and in particular to an LPG cylinder air tightness testing device. Background Technology

[0002] Liquefied petroleum gas (LPG) cylinders are steel cylinders used to store gas. After production, LPG cylinders need to undergo airtightness testing. The traditional testing method involves manually filling the LPG cylinder with high-pressure gas and then immersing it in a water tank to check for leaks. However, this method requires manually moving the cylinder in and out of the test tank, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The main purpose of this utility model is to provide a liquefied gas cylinder airtightness testing device to solve the problem that the existing technology requires manual removal of the cylinder from or into the test water tank, which is not only time-consuming and labor-intensive but also inefficient.

[0004] To solve the above problems, this utility model adopts the following technical solution: a liquefied petroleum gas cylinder airtightness testing device, including a box and a partition fixedly installed in the box. The partition divides the box into an immersion space and an operating space. A receiving plate is suspended above the immersion space, and the bottom surface of the receiving plate is rotatably connected to the partition. A lifting assembly is provided in the operating space, and a telescopic cylinder is provided at the upper part of the operating space. One end of the telescopic cylinder is rotatably connected to the end of the receiving plate away from the immersion space, and the other end of the telescopic cylinder is rotatably connected to the partition.

[0005] Furthermore, the receiving plate is L-shaped, including a horizontal plate suspended above the soaking space and a vertical plate fixed to the top surface of the horizontal plate. The vertical plate is located on the side of the horizontal plate away from the operating space. The end of the horizontal plate away from the vertical plate is rotatably connected to the partition and extends to provide an extension plate. The extension plate is located above the operating space, and one end of the telescopic cylinder is rotatably connected to the extension plate.

[0006] Furthermore, the operating space includes open platforms located on both sides of the box along its length and a cabinet disposed between the two open platforms. The telescopic cylinder is located inside the cabinet, and there are two lifting components, each located within one of the two open platforms.

[0007] Furthermore, each of the lifting components includes a screw vertically disposed within the open platform, a lifting plate screwed onto the screw, and a power unit for driving the screw to rotate, wherein the lifting plate is slidably connected to the side wall of the open platform.

[0008] Furthermore, the power unit includes a first motor fixedly mounted on one side of the housing, a first bevel gear fixedly sleeved on the bottom of the screw, the output end of the first motor extending through the side wall of the housing toward the screw, and a second bevel gear fixedly sleeved on the output end of the first motor, the first bevel gear meshing with the second bevel gear.

[0009] Furthermore, the receiving plate is evenly distributed with multiple through holes.

[0010] Furthermore, when the liquefied gas cylinder is placed on the horizontal plate of the receiving plate, the liquefied gas cylinder is fixedly connected to the vertical plate by straps.

[0011] Furthermore, the strap includes an elastic band and hooks disposed at both ends of the elastic band, with the two hooks engaging with corresponding through holes.

[0012] Furthermore, an air duct is provided above the soaking space. Under normal conditions, the air outlet of the air duct is located directly above the receiving plate, and a fan is connected to the air inlet of the air duct.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a rotating connection between the receiving plate and the partition plate, and by controlling the flipping of the receiving plate through the telescopic cylinder, it is not necessary to manually place the liquefied gas cylinder in the soaking space, saving time and effort. At the same time, the lifting component drives the liquefied gas cylinder to lift and lower, reducing the physical labor of the staff and improving the testing efficiency.

[0015] 2. Secure the LPG cylinder to one side of the vertical plate with straps to prevent the LPG cylinder from shaking during the rotation of the receiving plate, which would affect the test results;

[0016] 3. By installing a fan, air is blown directly onto the liquefied gas cylinder through the air duct, and the soaking liquid adhering to the surface of the liquefied gas cylinder can fall back into the soaking space through the through holes on the receiving plate, thereby reducing the waste of soaking liquid (resource).

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Please see Figures 1 to 3 As shown, a liquefied petroleum gas (LPG) cylinder airtightness testing device includes a housing 1, a partition 2, a receiving plate 3, a lifting assembly 4, and a telescopic cylinder 5. The housing 1 is a rectangular housing with an open top. The partition 2 is fixedly installed inside the housing 1 to divide the housing 1 into an immersion space 11 and an operating space 12. The operating space 12 is used to receive the lifting assembly 4 to move the LPG cylinder to a preset position. The immersion space 11 is filled with an immersion solution (e.g., water). During implementation, the LPG cylinder is immersed in the immersion space 11 to perform airtightness testing on the LPG cylinder.

[0027] The receiving plate 3 is used to receive liquefied petroleum gas (LPG) cylinders. The receiving plate 3 is suspended above the immersion space 11. The bottom surface of the receiving plate 3 is rotatably connected to the top of the partition 2. The telescopic cylinder 5 is located above the operating space 12. One end of the telescopic cylinder 5 is rotatably connected to the end of the receiving plate 3 away from the immersion space 11, and the other end of the telescopic cylinder 5 is rotatably connected to the partition 2. The telescopic cylinder 5 allows the receiving plate 3 to be flipped, thereby immersing the LPG cylinder in the immersion space 11.

[0028] Specifically, the receiving plate 3 is L-shaped, including a horizontal plate 31 and a vertical plate 32. The horizontal plate 31 is suspended above the soaking space 11, and the vertical plate 32 is fixed to the top surface of the horizontal plate 31, with the vertical plate 32 located on the side of the horizontal plate 31 away from the operating space 12. The end of the horizontal plate 31 away from the vertical plate 32 is rotatably connected to the partition plate 2 and extends to form an extension plate 33, which is located above the operating space 12. One end of the telescopic cylinder 5 is rotatably connected to the extension plate 33. Preferably, baffles 34 are fixed at both ends of the receiving plate 3 along its length, with one side of each baffle 34 fixedly connected to one end of the horizontal plate 31 and the vertical plate 32, respectively, to prevent the liquefied gas cylinder from falling.

[0029] Please see Figure 4 , Figure 5 As shown, during implementation, the worker places the liquefied petroleum gas (LPG) cylinder on the horizontal plate 31 of the receiving plate 3, and then activates the telescopic cylinder 5. As the output end of the telescopic cylinder 5 extends, its two ends are rotatably connected to the extension plate 33 and the partition plate 2, respectively. This causes the receiving plate 3 to rotate, immersing the LPG cylinder in the soaking space 11 to observe for leaks. After the LPG cylinder has been soaked for a preset time, the telescopic cylinder 5 is reset, which in turn resets the receiving plate 3, at which point the LPG cylinder is removed from the soaking space 11. This invention, by setting the receiving plate 3 and the partition plate 2 to rotate rotatably, and by controlling the rotation of the receiving plate 3 via the telescopic cylinder 5, eliminates the need for manual placement of the LPG cylinder in the soaking space 11, saving time and effort.

[0030] Preferably, the receiving plate 3 has multiple through holes 35 evenly distributed on it to facilitate the rapid encapsulation of the liquefied petroleum gas (LPG) cylinder by the soaking liquid in the soaking space 11. In this embodiment, when the LPG cylinder is placed on the horizontal plate 31 of the receiving plate 3, the LPG cylinder is fixedly connected to the vertical plate 32 by the straps 6. Specifically, the straps 6 include an elastic band 61 and hooks 62 disposed at both ends of the elastic band 61, with the two hooks 62 engaging with the corresponding through holes 35.

[0031] During implementation, the worker places the liquefied petroleum gas (LPG) cylinder on the horizontal plate 31 of the receiving plate 3. Then, the worker wraps the strap 6 around the side of the LPG cylinder away from the vertical plate 32. Next, the hooks 62 at both ends of the strap 6 are engaged with the corresponding suitable through holes 35. Because the elastic band 61 is elastic, engaging the hooks 62 at both ends of the strap 6 with the corresponding through holes 35 secures the LPG cylinder to one side of the vertical plate 32. This prevents the LPG cylinder from shaking during the reversal of the receiving plate 3.

[0032] Preferably, an air duct 7 is provided above the soaking space 11. Under normal conditions (when the equipment is not working, or when the telescopic cylinder 5 is in the retracted state), the air outlet of the air duct 7 is located directly above the receiving plate 3, and the air inlet of the air duct 7 is connected to a fan 8. In practice, after the liquefied gas cylinder has been tested in the soaking space 11, the telescopic cylinder 5 retracts and resets, causing the receiving plate 3 to reset. However, the outer surface of the liquefied gas cylinder is still covered with soaking liquid. At this time, the operator turns on the fan 8. Since the air outlet of the air duct 7 is located directly above the receiving plate 3, the fan 8 blows air directly onto the liquefied gas cylinder through the air duct 7. The soaking liquid adhering to the surface of the liquefied gas cylinder can fall back into the soaking space 11 through the through hole 35 on the receiving plate 3, thereby reducing the waste of soaking liquid (resource).

[0033] In this embodiment, the operating space 12 includes open platforms 121 located on both sides of the length of the housing 1 and a cabinet 122 disposed between the two open platforms 121. The telescopic cylinder 5 is located inside the cabinet 122, and there are two lifting components 4, which are respectively located inside the two open platforms 121. It should be noted that the open platform 121 is formed by the bottom surface, side walls, partition 2 of the housing 1, and the side walls of the cabinet 122, and has an accommodating space with openings at the top and front (the side away from the partition 2) to facilitate the transfer of liquefied gas cylinders to be tested or those that have been tested by staff.

[0034] In this embodiment, each lifting assembly 4 includes a screw 41, a lifting plate 42, and a power unit. The screw 41 is vertically disposed inside the open platform 121 and is rotatably connected to the bottom surface of the open platform 121. The lifting plate 42 is sleeved on the outside of the screw 41 and screwed to the screw 41. At the same time, the outer edge of the lifting plate 42 is slidably connected to the side wall of the open platform 121. The power unit is used to drive the screw 41 to rotate forward or in reverse, thereby driving the lifting plate 42 screwed to the screw 41 to rise or fall.

[0035] Specifically, such as Figure 3 As shown, the power unit includes a first motor 43, a first bevel gear 44, and a second bevel gear 45. The first motor 43 is fixedly mounted on one side of the housing 1. The first bevel gear 44 is fixedly sleeved on the bottom of the screw 41. The output end of the first motor 43 extends through the side wall of the housing 1 toward the screw 41. The second bevel gear 45 is fixedly sleeved on the output end of the first motor 43, and the first bevel gear 44 meshes with the second bevel gear 45. In operation, the first motor 43 rotates forward or backward, and through the transmission of the second bevel gear 45 and the first bevel gear 44, it drives the screw 41 to rotate, thereby driving the lifting plate 42 screwed to the screw 41 to rise or fall.

[0036] In the specific implementation of this utility model, the staff first places the liquefied gas cylinder to be tested on the lifting plate 42 of the open platform 121, and then starts the power unit of the lifting assembly 4. The first motor 43 drives the screw 41 to rotate through the transmission of the second bevel gear 45 and the first bevel gear 44, which in turn drives the lifting plate 42, which is screwed to the screw 41, to rise until the horizontal height of the top surface of the lifting plate 42 is equal to or higher than the horizontal height of the horizontal plate 31. At this time, the staff pushes the liquefied gas cylinder horizontally to push it onto the horizontal plate 31. In this way, by setting the lifting assembly 4 to drive the liquefied gas cylinder to rise and fall, the physical labor of the staff is reduced and the testing efficiency is improved.

[0037] It should be noted that the staff pushes the liquefied petroleum gas (LPG) cylinders so that multiple LPG cylinders are placed along the length of the horizontal plate 31. This allows for simultaneous testing of multiple LPG cylinders, further improving testing efficiency. After the LPG cylinders are placed, the staff uses straps 6 to secure them to one side of the vertical plate 32 to prevent the cylinders from shaking during the rotation of the receiving plate 3, which would affect the testing results.

[0038] After multiple LPG cylinders are secured, the telescopic cylinder 5 is activated, causing the receiving plate 3 to rotate until the vertical plate 32 rotates from a vertical position to a slightly horizontal position. At this time, multiple LPG cylinders are immersed in the soaking space 11 for sealing testing. After the test is completed, the telescopic cylinder 5 is activated to reset, causing the receiving plate 3 to reset as well. Then, the staff starts the blower 8, which blows air directly onto the LPG cylinders through the air duct 7. The soaking liquid adhering to the surface of the LPG cylinders can fall back into the soaking space 11 through the through hole 35 on the receiving plate 3, thereby reducing the waste of soaking liquid (resource).

[0039] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
