Description

Technical Field

[0001] The utility model relates to the field of leak detection devices, in particular to a leak detection device for square barrel processing. Background Technique

[0002] Since the cylinder can only be placed vertically, when placed horizontally, it is in line contact with the bearing surface, resulting in an unstable position when the cylinder is placed horizontally. The square structure of the square barrel makes it relatively stable when placed horizontally to adapt to its transportation.

[0003] In the leak detection of square barrels, generally, workers add liquid into the square barrel. When there are large cracks or holes in the square barrel, the liquid will flow down along the cracks or holes. When the staff observes the flowing water, the leak detection of the square barrel can be realized.

[0004] However, when there are small cracks or holes in the square barrel, the liquid can only seep out slowly, and the seepage speed is slow. It is difficult for the staff to observe the seepage phenomenon of the square barrel in a short time, resulting in poor leak detection effect of the square barrel. Content of the Utility Model

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a leak detection device for square barrel processing as Figures 1-4 shown, including:

[0025] A bottom plate, on the upper surface of which a bearing mechanism 1 is connected;

[0026] A connecting frame 2, which is arranged on one side of the bearing mechanism 1;

[0027] At the top of the connecting frame 2, an air inlet device 3 is connected. On one side of the connecting frame 2, a pressurizing device 4 is arranged. The pressurizing device 4 is installed on the upper surface of the bottom plate. The pressurizing device 4 is interconnected with the inner cavity of the air inlet device 3 through the connecting frame 2. The pressurizing device 4 is used to inject gas into the square barrel through the connecting frame 2 and the air inlet device 3 to pressurize the inner cavity of the square barrel.

[0028] Furthermore, the bearing mechanism 1 includes a bearing box 11 and support columns 12. The bearing box 11 is installed on the upper surface of the bottom plate. A plurality of support columns 12 are connected to the bottom end of the inner wall of the bearing box 11. The bearing box 11 facilitates the positioning of the square barrel. There is a certain distance between the square barrel and the inner side wall of the bearing box 11, making the position of the square barrel more stable during detection and also facilitating the storage of the flowing water. The bearing box 11 is made of a transparent material. The support columns 12 facilitate supporting the square barrel at a certain height to prevent it from directly adhering to the inner wall of the bearing box 11 and blocking the cracks and holes.

[0029] Furthermore, the air inlet device 3 includes a bellows 31 and a connecting mechanism 32. One end of the bellows 31 is connected to the connecting frame 2 and the inner cavities are interconnected. The other end of the bellows 31 is connected to the connecting mechanism 32. The connecting mechanism 32 is used to connect to the square barrel. By using the bellows 31, it is convenient to adapt to square barrels of different heights.

[0030] Further, the connecting mechanism 32 includes a connecting cover 321, a connecting pipe 322 and a connecting ball head 323. An internal thread is provided inside the connecting cover 321. The connecting pipe 322 is connected to the top end of the connecting cover 321. A ball groove is provided inside the connecting pipe 322. The connecting ball head 323 is rotatably arranged inside the ball groove. The top end of the connecting ball head 323 is connected to the corrugated pipe 31. A sealing ring 3231 is fixedly sleeved on the outer wall of the connecting ball head 323. An annular groove is provided on the inner wall of the ball groove. The sealing ring 3231 is matched with the inner cavity of the annular groove. The connecting cover 321 is convenient for threaded connection with the barrel opening of the square barrel, realizing the connection between the air inlet device 3 and the square barrel, so as to block the only open position of the square barrel. Then, through the cooperation between the connecting pipe 322 and the connecting ball head 323, when the connecting cover 321 is threadedly installed, it will not drive the rotation of the corrugated pipe 31, nor will it cause the torsion of the corrugated pipe 31. Through the setting of the sealing ring 3231, the sealing degree between the connecting ball head 323 and the connecting pipe 322 is higher.

[0031] Further, the pressurizing device 4 includes a fixed cylinder 41 and a threaded pressurizing mechanism 42. The fixed cylinder 41 is installed on the upper surface of the bottom plate. The threaded pressurizing mechanism 42 is movably inserted into the inner cavity of the fixed cylinder 41. The threaded pressurizing mechanism 42 includes a threaded rod 421, a piston 422 and a sealing sleeve 423. A nut seat is fixedly connected to the top end of the fixed cylinder 41. The threaded rod 421 is threadedly inserted through the nut seat. The piston 422 is rotatably connected to the bottom of the threaded rod 421. The sealing sleeve 423 is movably sleeved on the outside of the piston 422. The connecting ball head 323 is convenient for ensuring the fit with the inner wall of the fixed cylinder 41, preventing a large degree of air leakage. Through the threaded insertion between the threaded rod 421 and the nut seat, when the threaded rod 421 is rotated, the piston 422 can be pushed up and down, realizing the pressurization of the inner cavity of the fixed cylinder 41, and thus facilitating the pressurization of the square barrel.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
