[0026] The existing pipe assembly needs to be plugged with a pipe opening clamp to check for leaks, and then at least one pipe opening is reserved as a high-pressure air interface to be pressurized in a water tank to observe whether the entire closed system has leaks. When there are several branches on the pipeline, each branch needs to be plugged with a clamp, and the clamp needs to be removed from each pipe opening again after the test, which is inefficient.

[0027] In view of the above technical problems, the utility model provides a pipe assembly leak detection device 100. The pipe assembly 50 generally includes a main pipe 51 and a branch pipe 52. The pipe assembly leak detection device 100 can simultaneously block or unblock each branch pipe 52 in the pipe assembly 50, thereby improving the test efficiency.

[0028] See also Figure 1-Figure 2 The pipe assembly leak detection device 100 includes a frame 10, a power assembly 20, a transmission assembly 30, a sealing assembly 40 and a pipe assembly 50. The power assembly 20 is installed on the frame 10, and the transmission assembly 30 is connected to the power assembly 20 and is movably connected to the frame 10. With the driving of the power assembly 20, the transmission assembly 30 can move relative to the frame 10. The sealing assembly 40 is connected to the frame 10. Along the movement of the transmission assembly 30, the transmission assembly 30 is located between the power assembly 20 and the sealing assembly 40. The transmission assembly 30 can be arranged close to or away from the sealing assembly 40; the side of the transmission assembly 30 facing away from the power assembly 20 is used to connect the pipe assembly 50 to be detected. In this way, the power component 20 can drive the transmission component 30 to move by connecting with the transmission component 30, and the transmission component 30 then drives the tube component 50 to abut against the sealing component 40. Since the tube component 50 moves as a whole, the multiple branch pipes 52 on the tube component 50 can abut against the sealing component 40 at the same time, thereby achieving simultaneous sealing of the multiple branch pipes 52 without the need to clamp and seal each branch pipe 52. When the test is completed, the multiple branch pipes 52 can also contact and abut against the sealing component 40 at the same time, thereby improving the test efficiency.

[0029] Specifically, the frame 10 includes at least two cross beams 11 and at least two vertical rods 12, the at least two cross beams 11 are arranged at intervals, the at least two vertical rods 12 are arranged at intervals, and the two ends of the cross beam 11 are respectively connected to the two vertical rods 12. In this way, the cross beams 11 and the vertical rods 12 can support each other, thereby improving the overall strength of the frame 10, and a space for installing various components can be formed between the cross beams 11 and the vertical rods 12, thereby protecting the various components installed therein.

[0030] In this embodiment, there are two cross beams 11 and two vertical rods 12. In other embodiments, in order to improve the structural strength of the frame 10, the number of cross beams 11 and vertical rods 12 may be increased accordingly and is not limited to two in this embodiment.

[0031] Specifically, the cross beam 11 is a plate-like structure, so as to facilitate the installation of the power assembly 20 and the sealing assembly 40, and the vertical rod 12 is a rod-like structure, so as to ensure strength while reducing consumables.

[0032] The transmission assembly 30 includes a movable crossbeam 31, and movable holes are respectively opened at both ends of the movable crossbeam 31. Two vertical rods 12 are respectively inserted into the movable holes, and the movable crossbeam 31 can move along the length direction of the vertical rods 12. In this way, the vertical rods 12 can guide the movement of the movable crossbeam 31. When the driving assembly drives the movable crossbeam 31 to move, the two movable holes at both ends of the movable crossbeam 31 and the two vertical rods 12 produce a relative limiting effect, so that the movement of the movable crossbeam 31 is more stable.

[0033] The transmission assembly 30 further includes a connecting block 32, which is connected to the side of the movable crossbeam away from the power assembly 20, and the end of the connecting block 32 away from the movable crossbeam 31 is used to connect with the pipe assembly 50. In this way, the connecting block 32 connects the transmission assembly 30 and the pipe assembly 50 and ensures the connection strength between the two.

[0034] In this embodiment, there are at least two connecting blocks 32, which are arranged at intervals along the length direction of the movable crossbeam 31. The end of the connecting block 32 away from the movable crossbeam 31 is recessed inward to form an arc surface, which is used to fit the outer wall of the pipe assembly 50, so that the connection between the connecting block 32 and the pipe assembly 50 is more tightly connected. In other embodiments, in order to improve the connection strength between the transmission assembly 30 and the pipe assembly 50, the number of connecting blocks 32 and the connection area between the transmission assembly 30 and / or the pipe assembly 50 can also be increased accordingly.

[0035] The power assembly 20 includes a power source 21 and a driving rod 22, the power source 21 and the driving rod 22 are connected, and can drive the driving rod 22 to move in a direction away from or close to the power source 21, and the end of the driving rod 22 away from the power source 21 is connected to the transmission assembly 30. In this way, the driving rod 22 can be extended or shortened by its own movement, thereby driving the movement of the transmission assembly 30, thereby achieving the blocking or unblocking of the pipe assembly 50.

[0036] In this embodiment, the power source 21 is an air pump, which is installed on the side of the beam 11 facing away from the other beam 11. One end of the driving rod 22 is connected to the air pump, and the other end passes through the beam 11 on which the air pump is installed and extends toward the other beam 11, thereby connecting to the transmission assembly 30.

[0037] The sealing assembly 40 is provided with a plurality of sealing grooves (not shown), and a branch pipe 52 is correspondingly embedded in each sealing groove to form a blockage. In other words, each branch pipe 52 can be correspondingly embedded in a separate sealing groove, thereby improving the blocking effect of the sealing assembly 40 on the branch pipe 52 of the pipe assembly 50, improving air tightness, and enhancing detection accuracy.

[0038] The sealing assembly 40 is also provided with an air inlet 41, and the frame 10 is provided with a through hole 121 communicating with the air inlet 41, and the air inlet 41 is used to communicate with the pipe assembly 50. In this way, the branch pipe 52 of the pipe assembly 50 can extend into the air inlet 41, and the branch pipe 52 can be pressurized and input with gas through the through hole 121 and the air inlet 41 from the outside, so as to check the air tightness of the pipe assembly 50.

[0039] In other embodiments, two branch pipes 52 may be provided to extend into the air inlet 41, thereby increasing the flow area of ​​the gas.

[0040] A pressure tube 53 can also be added to the main pipe 51. The pressure tube 53 is connected to the main pipe 51 and extends away from the pressure tube 53. When the pipe assembly 50 is immersed in water for water inspection, the pressure tube 53 can extend out of the water surface. The user can input gas through the pressure tube 53 to pressurize it, thereby detecting the air tightness of the pipe assembly 50.

[0041] In this embodiment, the sealing component 40 uses a soft silicone pad, which can be deformed accordingly according to the shape of the pipe opening of the branch pipe 52, thereby improving the contact tightness with the pipe opening of the branch pipe 52, thereby improving the sealing performance.

[0042] The utility model also provides a detection system, comprising the pipe assembly leak detection device 100 as described above.

[0043] Compared with the prior art, the utility model drives the transmission assembly 30 to move by connecting the power assembly 20 with the transmission assembly 30, and the transmission assembly 30 then drives the tube assembly 50 to abut against the sealing assembly 40. Since the tube assembly 50 moves as a whole, the multiple branch pipes 52 on the tube assembly 50 can abut against the sealing assembly 40 at the same time, thereby achieving simultaneous sealing of the multiple branch pipes 52 without the need to clamp and seal each branch pipe 52. When the test is completed, the multiple branch pipes 52 can also contact and abut against the sealing assembly 40 at the same time, thereby improving the test efficiency.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
