Description

Technical Field

[0001] This utility model relates to the field of leakage detection technology, specifically a leakage detection device for joints in sewage tanks. Background Technology

[0002] Wastewater treatment tanks are facilities used to collect, store, and pre-treat wastewater from various sources. They reduce pollution and recycle water resources through physical, chemical, or biological methods, playing an important role in environmental protection and water resource management. Leakage is prone to occur at the joints of wastewater treatment tanks. During the production and processing of wastewater treatment tanks, it is necessary to detect leakage at the joints. The existing detection method is to inject water into the wastewater treatment tank and observe whether there are obvious wet stains, watermarks, or leakage traces around the tank and at the joints. However, this method is time-consuming and labor-intensive, and human observation may lead to false detections. Utility Model Content

A booster pump 3 is fixedly connected to the top of the mobile cart 1. A winding assembly 5 is provided on the side of the top of the mobile cart 1 away from the booster pump 3. A connecting hose 4 is fixedly connected to the side of the booster pump 3 near the winding assembly 5. The winding assembly 5 includes a mounting frame 501 on the top of the mobile cart 1. Both sides of the bottom end of the mounting frame 501 are fixedly connected to the top of the mobile cart 1. A rotating roller 502 is provided inside the mounting frame 501. The connecting hose 4 is wound around the outside of the rotating roller 502. A detection component 6 is provided at the end of the connecting hose 4 away from the booster pump 3. The detection component 6 includes a U-shaped... The frame 601 has a connecting air pipe 602 running through the center of its top. An electromagnetic pressure relief valve 604 is fitted on the outer wall of the connecting air pipe 602. A pressure gauge 603 is connected to the top of the connecting air pipe 602 by fastening bolts. Arc plates 606 are symmetrically arranged at both ends of the inner side of the U-shaped frame 601. A rotating screw 607 is rotatably connected to the side of the two arc plates 606 that are far apart from each other through a bearing. A sleeve rod 609 is fixedly connected to the upper and lower ends of the two arc plates 606 that are far apart from each other. A sleeve 608 is fixedly connected to the upper and lower ends of the inner walls on both sides of the U-shaped frame 601. A spring 610 is installed inside each of the four sleeves 608. A pressure sensor 611 is connected to one side of the bottom of the U-shaped frame 601.

[0025] like Figure 3 , Figure 4 As shown, the ends of the two rotating lead screws 607 away from the arc plate 606 pass through both sides of the U-shaped frame 601, and the four sleeve rods 609 are respectively set with the four sleeves 608. The ends of the four sleeve rods 609 away from the arc plate 606 extend into the interior of the four sleeves 608. The top of the connecting pipe 602 is fixedly connected to the end of the connecting hose 4 away from the booster pump 3. A sealing gasket 605 is adhered to the inner wall of the top of the U-shaped frame 601.

[0026] like Figure 1 , Figure 2 As shown, one end of the rotating roller 502 is rotatably connected to the inner wall of the mounting frame 501, and the other end of the rotating roller 502 passes through the side wall of the mounting frame 501 and is fixedly connected to a worm gear 503. A worm 504 is provided below the worm gear 503, and the worm 504 and the worm gear 503 are meshed. Both ends of the worm 504 are rotatably connected to fixed plates 505.

The end of the handwheel 506 near the fixed plate 505 passes through the fixed plate 505 and is fixedly connected to the worm 504.

[0027] The working process of this utility model is as follows: During use, the worm gear 504 is rotated by the handwheel 506. The worm gear 504 drives the rotating roller 502 to unwind the connecting hose 4. The U-shaped frame 601 is placed on top of the inlet of the sewage tank to be tested. The two rotating screws 607 are rotated to push the two arc plates 606 closer together and clamp them on both sides of the sewage tank inlet to fix the U-shaped frame 601. The sealing gasket 605 on the inner wall of the top of the U-shaped frame 601 can enhance the sealing between the two. The pressure sensor 611 at the bottom of the U-shaped frame 601 extends into the inside of the sewage tank. The booster pump 3 pressurizes the inside of the sewage tank through the connecting hose 4 and the connecting air pipe 602. The pressure sensor 611 can detect the pressure inside the sewage tank. If the pressure inside the sewage tank does not change, or if the pressure decreases after the sewage tank is pressurized to a certain value and left to stand for a period of time, it indicates that there is leakage at the joint of the sewage tank.
