Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0037] It should be noted that the welding joint 200 detected by the welding joint leak detection device of the embodiments of the present application is a water tank 260, but the welding joint 200 detected by the welding joint leak detection device of the embodiments of the present application is not limited to the water tank 260, and can also be other objects having a gap between two adjacent welding joints, such as pipe or plate.

[0038] Reference Figures 1 to 4 , the welding joint leak detection device according to the first aspect of the embodiments of the present application comprises a container 120 and a detection module 300. The container 120 is provided with a detection groove 121, the detection groove 121 is used to contain liquid, and the detection groove 121 is also used to accommodate the water tank 260. The welding joint 240 (refer to Figure 4 ) of the water tank 260 located in the detection groove 121 can be immersed in the liquid in the detection groove 121.

[0039] The detection module 300 comprises a gas supply pipeline 330 and a pipe joint 340, the gas supply pipeline 330 is used to input positive pressure gas to the pipe joint 340, and the pipe joint 340 is used to connect with the water tank 260. When the pipe joint 340 is connected with the water tank 260, the pipe joint 340 is in communication with the gap 250 (refer to Figure 3 ) between the two adjacent welding joints 240 of the water tank 260.

[0040] The welding joint leak detection device according to the embodiments of the present application has at least the following beneficial effects: after the pipe joint 340 inputs positive pressure gas into the gap 250 between the two adjacent welding joints 240 of the water tank 260, if the sealing performance of the welding joint 240 is poor, the welding joint 240 immersed in the liquid will appear bubbles; by actively inputting positive pressure gas into the gap 250 between the two adjacent welding joints 240, the sealing performance detection of the welding joint 240 can be quickly completed, thereby the sealing performance detection efficiency of the welding joint 240 of the water tank 260 can be effectively improved.

[0041] Specifically, referring to Figure 2 , the water tank 260 usually comprises two first side plates 210, two second side plates 230 and a bottom plate 220, the two first side plates 210, the two second side plates 230 and the bottom plate 220 are welded at the splicing position, thereby forming the water tank 260.

[0042] As shown in Figure 3 and Figure 4 , when the front end of the first side plate 210 is spliced with the left end of the second side plate 230, the left end of the second side plate 230 forms a weld 240 on the inner side and the outer side, and the welds 240 have a gap 250 therebetween. As shown in Figure 2 and Figure 5 , the gaps 250 in the water tank 260 are connected to each other to form a passage as shown in Figure 5 .

[0043] Specifically, the positive pressure gas can be compressed air, compressed nitrogen or compressed inert gas.

[0044] As shown in Figure 4 , in some embodiments of the present application, the pipe joint 340 is used to be screwed with the water tank 260.

[0045] By screwing the pipe joint 340 with the water tank 260, the installation and disassembly of the pipe joint 340 and the water tank 260 can be quickly realized, thereby facilitating the improvement of the detection efficiency.

[0046] In addition, the sealing performance of the threaded connection is good, thereby facilitating the improvement of the sealing performance of the pipe joint 340 and the water tank 260.

[0047] As shown in Figure 4 , in some embodiments of the present application, the pipe joint 340 is used to be inserted with the water tank 260, and the pipe joint 340 can be connected with the water tank 260 through a fastener.

[0048] The pipe joint 340 is inserted with the water tank 260, and the pipe joint 340 is connected with the water tank 260 through a fastener, which can also quickly realize the installation and disassembly of the pipe joint 340 and the water tank 260, thereby facilitating the improvement of the detection efficiency.

[0049] It should be noted that the pipe joint 340 is inserted with the water tank 260, which means that the water tank 260 is provided with a mounting hole, and the pipe joint 340 is inserted into the mounting hole. The fastener refers to a bolt, a stud, etc.

[0050] As shown in Figure 1 , in some embodiments of the present application, the detection groove 121 is used to accommodate two or more water tanks 260. The number of pipe joints 340 is not less than the number of water tanks 260 accommodated by the detection groove 121, and each water tank 260 can be connected with at least one pipe joint 340.

[0051] By making the detection groove 121 accommodate two or more water tanks 260, the sealing performance detection of two or more water tanks 260 can be completed at one time, thereby facilitating the improvement of the sealing performance detection efficiency of the water tank 260.

[0052] Specifically, each water tank 260 can be connected with one, two, three or four pipe joints 340.

[0053] With reference to Figure 1 In the improved scheme of the above embodiment, each water tank 260 can be connected with one pipe joint 340.

[0054] By connecting the water tank 260 with the pipe joint 340 one by one, the number of pipe joints 340 can be reduced, thereby reducing the equipment cost of the weld seam tightness detection device.

[0055] In some embodiments of the present application, the detection tank 121 is used to accommodate three, four or five water tanks 260.

[0056] When the number of water tanks 260 that the detection tank 121 can accommodate is three, four or five, the weld seam tightness detection device has a high detection efficiency under the condition of appropriate floor area, and the weld seam tightness detection device is more convenient to use.

If the output gas pressure of the gas supply pipeline 330 is too low, the defective weld seam 240 can be difficult to detect. If the output gas pressure of the gas supply pipeline 330 is too high, energy waste is easily caused.

[0059] With reference to Figure 1 In some embodiments of the present application, the detection module 300 further comprises a speed regulating valve 320, the speed regulating valve 320 is installed on the gas supply pipeline 330, and the speed regulating valve 320 is used to adjust the output flow of the gas supply pipeline 330.

If the output flow of the gas supply pipeline 330 is too small, the defective weld seam 240 can be difficult to detect. If the output flow of the gas supply pipeline 330 is too large, energy waste is easily caused.

[0061] With reference to Figure 1 In some embodiments of the present application, the weld seam tightness detection device further comprises a liquid inlet pipeline 110, the liquid inlet pipeline 110 is used to input liquid into the detection tank 121.
