Description

Technical Field

[0001] This utility model relates to the field of leakage sealing devices for municipal drainage pipes, and in particular to a rapid leakage sealing device for municipal drainage pipes. Background Technology

[0002] Municipal drainage pipes are a key component of urban infrastructure, primarily used to collect and discharge domestic sewage, rainwater, and other wastewater. Their function is to prevent urban flooding and sewage leakage, ensuring environmental sanitation and the quality of life for residents. Municipal drainage pipes can be categorized by function into rainwater pipes, sewage pipes, and combined sewer pipes. Rainwater pipes mainly discharge rainwater, sewage pipes handle domestic and industrial wastewater, while combined sewer pipes handle both rainwater and sewage. Municipal drainage pipes typically utilize corrosion-resistant and high-strength materials such as reinforced concrete, PVC, and cast iron. A rapid leak-sealing device for municipal drainage pipes is an emergency repair tool specifically designed to address leaks in municipal drainage pipes. It uses physical or chemical methods to quickly seal leaks, ensuring the normal operation of the drainage system and reducing water waste and environmental pollution.

[0003] Existing municipal drainage pipe leakage sealing devices have low operational efficiency and complex procedures. Construction personnel need a high level of technical expertise to complete the sealing work, which limits the use of devices by technicians at different levels, increases the difficulty of construction, and may not be able to quickly and stably fix the sealing device, affecting the sealing effect and construction efficiency. In the case of emergency repairs, some sealing devices do not have the function of quickly sealing leaks. They usually block the water inlet of the pipe, but the water cannot be drained, causing the water in the drainage pipe to accumulate more and more, creating a vicious cycle, leading to rising water levels, damage to soil structure, and even damage to the foundation of surrounding buildings.

[0004] Therefore, those skilled in the art have provided a rapid leak-stopping device for municipal drainage pipes to solve the problems mentioned in the background art. Utility Model Content

Compared with existing municipal drainage pipe leak-stopping devices, this device features a fixing mechanism that rotates the main gear by rotating the force rod, which in turn drives the secondary gear to rotate and fix the threaded rod. This fixing mechanism not only effectively improves operational efficiency but also simplifies the operation process, significantly reduces the technical requirements for construction personnel, adapts to the needs of technicians at different levels, and reduces construction difficulty.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rapid leak-stopping device for municipal drainage pipes includes a first arc-shaped pressure plate, a second arc-shaped pressure plate on one side of the first arc-shaped pressure plate, and vertical plates fixedly connected to the front outer walls of both the first and second arc-shaped pressure plates. A fixing mechanism is provided on one outer wall of one side of the vertical plate. The fixing mechanism includes a gear box fixedly connected to the outer wall of one side of the vertical plate. A main gear is provided in the middle of the inner wall of the gear box, and auxiliary gears are provided at the upper and lower ends of the main gear. Threaded rods are fixedly connected to the outer wall of one side of each auxiliary gear.

[0011] The above technical solution allows the threaded rod to move back and forth via the first threaded groove.

[0012] Furthermore, an air nozzle groove is provided in the middle of the outer wall of one side of the first arc-shaped pressure plate, and the outer wall of the air nozzle is in close contact with the inner wall of the air nozzle groove.

[0013] Through the above technical solution, the air nozzle can extend out of the outer wall of the first arc-shaped pressure plate through the air nozzle groove.

[0014] Furthermore, all the main gears are meshed with the secondary gears;

[0015] The above technical solution can drive the secondary gear to rotate.

[0016] Furthermore, a hinge rod is provided on the side of the first arc pressure plate and the second arc pressure plate that are close to each other, and the first arc pressure plate and the second arc pressure plate are hinged together by the hinge rod.

[0017] The above technical solution enables the first arc pressure plate and the second arc pressure plate to be hinged together.

[0018] Furthermore, a second threaded groove is provided at both the upper and lower ends of the vertical plate on the other side;

[0019] The above technical solution allows the threaded rod to rotate within the second threaded groove by providing a second threaded groove.

[0020] Furthermore, the shaft of the threaded rod is threadedly connected to the first threaded groove and the second threaded groove respectively;

[0021] Through the above technical solution, the rod body of the threaded rod is threadedly connected to the first threaded groove and the second threaded groove respectively, thereby fixing the first arc pressure plate and the second arc pressure plate together.

[0022] Furthermore, a force rod is fixedly connected to one side of the outer wall of the main gear;

[0023] The above technical solution allows the main gear to rotate via a lever.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a rapid leak-stopping device for municipal drainage pipes. Compared with existing municipal drainage pipe leak-stopping devices, the device is equipped with a fixing mechanism. By rotating the force rod, the main gear is rotated, which in turn drives the secondary gear to rotate and fix the threaded rod. The fixing mechanism not only effectively improves the operating efficiency, but also significantly reduces the technical requirements of construction personnel by simplifying the operation process, adapting to the needs of technical personnel at different levels, and reducing the difficulty of construction.

[0026] 2. The present invention proposes a rapid leak-stopping device for municipal drainage pipes. Through the water-blocking mechanism, an air bladder is inflated through an air nozzle. The outer wall of the air bladder then fits tightly against the leak in the drainage pipe, forming an effective sealing barrier. In emergency situations, it can quickly stop water leakage, thereby ensuring the normal use of municipal drainage pipes and preventing further damage and secondary losses to the surrounding environment caused by leaking water.

[0040] Reference Figure 1 , Figure 2 and Figure 4 One embodiment provided by this utility model:

[0041] A rapid leak-stopping device for municipal drainage pipes includes a first arc-shaped pressure plate 2, a second arc-shaped pressure plate 4 on one side of the first arc-shaped pressure plate 2, and vertical plates 5 fixedly connected to the front outer walls of both the first arc-shaped pressure plate 2 and the second arc-shaped pressure plate 4. A fixing mechanism 1 is provided on one outer wall of one side of the vertical plate 5. The fixing mechanism 1 includes a gear box 101 fixedly connected to one outer wall of the vertical plate 5. A main gear 105 is provided in the middle of the inner wall of the gear box 101. A secondary gear 106 is provided at the upper and lower ends of the main gear 105.

[0042] The first arc pressure plate 2 and the second arc pressure plate 4 are provided with a water blocking mechanism 6. The water blocking mechanism 6 includes an airbag 601 provided on one side of the inner wall of the first arc pressure plate 2. An air nozzle 602 is fixedly connected to one side of the outer wall of the airbag 601. An air nozzle cap 603 is provided on the outer wall of the air nozzle 602 away from the airbag 601. An airbag cavity 604 is opened inside the airbag 601.

[0043] The quick-sealing device can be quickly fitted onto the body of the drain pipe.

[0044] The gear box 101 has a first threaded groove 107 at both the upper and lower ends of the inner wall on one side. The threaded rod 102 can be moved back and forth through the first threaded groove 107. The first arc pressure plate 2 has an air nozzle groove 7 in the middle of the outer wall on one side. The outer wall of the air nozzle 602 is in close contact with the inner wall of the air nozzle groove 7. The air nozzle 602 can extend out of the outer wall of the first arc pressure plate 2 through the air nozzle groove 7.

[0045] Reference Figure 5 and Figure 6 The main gear 105 is meshed with the secondary gear 106, thereby driving the secondary gear 106 to rotate. The first arc plate 2 and the second arc plate 4 are provided with a hinge rod 3 on their respective sides. The first arc plate 2 and the second arc plate 4 are hinged together by the hinge rod 3, thereby allowing the first arc plate 2 and the second arc plate 4 to be hinged together.

[0046] Reference Figure 2 and Figure 4 On the other side, the upper and lower ends of the vertical plate 5 are provided with second threaded grooves 103. By providing second threaded grooves 103, the threaded rod 102 can rotate in the second threaded grooves 103. The rod body of the threaded rod 102 is threadedly connected to the first threaded groove 107 and the second threaded groove 103 respectively.

[0047] Reference Figure 1 and Figure 4 The first arc plate 2 and the second arc plate 4 are fixed together by threaded connection of the rod body of the threaded rod 102 to the first threaded groove 107 and the second threaded groove 103 respectively.

[0048] Working principle: When using this device, the lever 104 is used to rotate the second threaded groove 103 on the second arc-shaped pressure plate 4 outwards. Then, the hinge rod 3 is used to open the first arc-shaped pressure plate 2 and the second arc-shaped pressure plate 4 to both sides. The airbag 601 is then fitted onto the leaking part of the drain pipe. The hinge rod 3 is then used again to close the first arc-shaped pressure plate 2 and the second arc-shaped pressure plate 4. Finally, the lever 104 rotates the main gear 105, which in turn drives the secondary gear 106 to rotate. The threaded rod 102 is rotated within the first threaded groove 107, causing it to move forward. Then, the threaded rod 102 rotates into the second threaded groove 103 on the second arc-shaped pressure plate 4. The inflation device then inflates the air chamber 604 of the airbag 601 through the air nozzle 602 until the airbag 601 is tightly fitted to the leak, preventing further leakage. Finally, the air nozzle cap 603 is used to seal the air nozzle 602 to prevent contaminants from accumulating at the air nozzle 602.
