Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a seepage prevention device for water supply and drainage pipes in building engineering. Background Technology

[0002] Building drainage and seepage prevention devices are key facilities for preventing water leakage and protecting building structures. By using seepage-proof materials, sealing joints, and strengthening pipe connections, they ensure that drainage pipes do not leak during long-term use. They can effectively prevent water from invading the foundation or the surrounding environment, avoiding problems such as soil erosion, foundation settlement, and mold growth caused by water seepage, and ensuring the structural safety and functionality of buildings.

[0003] Chinese patent publication number CN212131710U discloses a building drainage pipe, including a drainage pipe body. The outer wall of the drainage pipe body is provided with an upper ring and a lower ring, which are connected by a hinge. A clamp is provided on the outer wall of the drainage pipe body, with one clamp on each side of the upper and lower rings. The inner wall of the upper ring is provided with a first sound insulation layer, the inner wall of the first sound insulation layer is provided with a second sound insulation layer, the inner wall of the second sound insulation layer is provided with a first protective mesh, the inner wall of the first protective mesh is provided with foam adhesive, and the inner wall of the foam adhesive is provided with a second protective mesh. This building drainage pipe, by providing upper and lower rings on the outer wall of the drainage pipe body and using clamps to restrict the position of the upper and lower rings, prevents movement of the upper and lower rings. Simultaneously, the first and second sound insulation layers and foam adhesive inside the upper and lower rings provide good sound insulation for the drainage pipe body, ensuring people's sleep at night.

[0004] However, the current drainage pipes have the following problems: they do not have a seepage prevention effect, which will lead to the accumulation of leakage problems, causing the overall waterproofing of the building to fail, and requiring frequent repairs and replacements in the later stage, increasing maintenance costs and time. Therefore, we propose a seepage prevention device for water supply and drainage pipes in building engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a seepage prevention device for water supply and drainage pipes in building engineering, which can solve the problem that the drainage pipes in the related technology do not have a seepage prevention effect, which leads to the accumulation of leakage problems, resulting in the failure of the overall waterproofing of the building, and the need for frequent maintenance and replacement in the later stage, increasing maintenance costs and time.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A seepage prevention device for water supply and drainage pipes in building engineering includes a first drainage pipe and a second drainage pipe. Sealing devices are provided on the circumferential surfaces of the first and second drainage pipes. Each sealing device includes a connecting housing. The inner wall of the connecting housing is fixedly connected to the circumferential surfaces of the first and second drainage pipes. An L-shaped plate is fixedly connected to the circumferential surface of the connecting housing. A cylinder is fixedly connected to the inner wall of the L-shaped plate. The telescopic end of the cylinder passes through and slides on the circumferential surface of the connecting housing. An arc-shaped clamping block is fixedly connected to the telescopic end of the cylinder. A sealing gasket is fixedly connected to the inner wall of the arc-shaped clamping block. When the cylinder is activated, the telescopic end of the cylinder moves towards a point on the drainage pipe, causing the arc-shaped clamping block to move. The movement of the arc-shaped clamping block causes the sealing gasket to move, and the moving sealing gasket comes into contact with the connection point of the first and second drainage pipes.

[0008] Two connecting housings are provided and are arranged circumferentially on the circumferential surfaces of drain pipe one and drain pipe two.

[0009] The first and second drain pipes are located on the movement trajectory of the arc-shaped clamping block, and the sealing gasket is made of nitrile rubber.

[0010] A warning device is provided on the circumferential surface of the arc-shaped clamping block. The warning device includes a long rod, the bottom of which is fixedly connected to the circumferential surface of the arc-shaped clamping block. The long rod passes through and slides on the circumferential surface of the connecting housing. A protruding rod is fixedly connected to the side of the long rod. An alarm is fixedly connected to the inner wall of the L-shaped plate. A warning light is fixedly connected to the side of the L-shaped plate. When a leak occurs, the sealing gasket will be lifted by the leaking water flow, thereby causing the arc-shaped clamping block to move. The movement of the arc-shaped clamping block causes the long rod to move, which in turn causes the protruding rod to move. During the movement of the protruding rod, it comes into contact with the alarm, and the alarm controls the warning light to start working.

[0011] The alarm is located on the movement trajectory of the protruding rod, and the warning light is electrically connected to the alarm.

[0012] The inner diameter of the arc-shaped clamp is equal to the outer diameter of the drain pipe, and there is a gap between the long rod and the L-shaped plate.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention utilizes a sealing device to coordinate the connecting housing, L-shaped plate, cylinder, arc-shaped clamp, and sealing gasket. Activating the cylinder causes its extension end to move towards a drain pipe, which in turn moves the arc-shaped clamp. This movement of the clamp then moves the sealing gasket, which adheres to the connection point between drain pipe one and drain pipe two. By using a sealing gasket at the connection, leakage is significantly reduced, thus decreasing subsequent maintenance and replacement costs. It also prevents soil erosion and structural damage caused by water leakage, extending the service life of the pipeline system. The sealing gasket fills the gaps at the connection, preventing water leakage, especially under pressure changes or pipe vibration. It maintains the tightness of the connection, ensuring the drainage system's seepage prevention effect. Furthermore, it prevents loosening or cracking at the connection, thereby improving the long-term stability of the pipe connection.

[0015] This invention utilizes a warning device that coordinates a long rod, a protruding rod, an alarm, and a warning light. When a leak occurs, the leaking water flow lifts the sealing gasket, causing the arc-shaped clamp to move. This movement of the clamp moves the long rod, which in turn moves the protruding rod. During this movement, the protruding rod contacts the alarm, activating the warning light. The warning light helps workers identify the leak at a connection point, saving them time searching for the leak and improving maintenance efficiency. The warning light also provides an early warning of equipment malfunctions, prompting workers to take preventative measures. Furthermore, the early warning system helps prevent problems from escalating or worsening, allowing for timely maintenance and repair, thus extending the equipment's lifespan and reducing damage caused by equipment failure.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, a seepage prevention device for water supply and drainage pipes in building engineering includes a first drainage pipe 1 and a second drainage pipe 2. A sealing device 3 is provided on the circumferential surface of both drainage pipes 1 and 2. The sealing device 3 includes a connecting housing 31, the inner wall of which is fixedly connected to the circumferential surface of the first drainage pipe 1 and the second drainage pipe 2. An L-shaped plate 32 is fixedly connected to the circumferential surface of the connecting housing 31, and a cylinder 33 is fixedly connected to the inner wall of the L-shaped plate 32. The telescopic end of the cylinder 33 passes through and slides on the circumference of the connecting housing 31. On the surface, an arc-shaped clamping block 34 is fixedly connected to the telescopic end of the cylinder 33, and a sealing gasket 35 is fixedly connected to the inner wall of the arc-shaped clamping block 34. Two connecting housings 31 are provided and are arranged in a circumferential array on the circumferential surface of drain pipe 1 and drain pipe 2 to enhance the sealing effect. Drain pipe 1 and drain pipe 2 are located on the movement trajectory of the arc-shaped clamping block 34, which can seal the connection between drain pipe 1 and drain pipe 2. The sealing gasket 35 is made of nitrile rubber, which has good sealing performance and durability.

[0025] According to the above structure, when cylinder 33 is activated, the telescopic end of cylinder 33 moves towards drain pipe 1, which in turn moves the arc-shaped clamp 34. The movement of the arc-shaped clamp 34 causes the sealing gasket 35 to move. The sealing gasket 35 then fits into the connection between drain pipe 1 and drain pipe 2. By using the sealing gasket 35 at the connection, leakage problems can be greatly reduced, thereby reducing the cost of later maintenance and replacement, avoiding soil erosion and building structure damage caused by water leakage, and extending the service life of the pipeline system. The sealing gasket 35 can fill the gap at the connection, preventing water from leaking from the joint. Especially under pressure changes or pipeline vibration, the sealing gasket 35 can maintain the tightness of the connection, ensuring the seepage prevention effect of the drainage system. It also prevents the connection from loosening or cracking, thereby improving the long-term stability of the pipeline connection.

[0026] like Figures 1-5A warning device 4 is provided on the circumferential surface of the arc-shaped clamp 34 shown. The warning device 4 includes a long rod 41. The bottom of the long rod 41 is fixedly connected to the circumferential surface of the arc-shaped clamp 34. The long rod 41 passes through and slides on the circumferential surface of the connecting housing 31. A protruding rod 42 is fixedly connected to the side of the long rod 41. An alarm 43 is fixedly connected to the inner wall of the L-shaped plate 32. The alarm 43 can detect abnormalities in time and issue an alarm immediately to remind residents or staff to take emergency measures, thereby avoiding further expansion of the accident and ensuring personal and property safety. A warning light 44 is fixedly connected to the side of the L-shaped plate 32 to indicate which connection point has leaked. The alarm 43 is located on the movement trajectory of the protruding rod 42. When a leak occurs, the protruding rod 42 moves upward and will abut against the alarm 43, thereby triggering an alarm. The warning light 44 and the alarm 43 are electrically connected. The inner diameter of the arc-shaped clamp 34 is equal to the outer diameter of the drain pipe 1. A gap is provided between the long rod 41 and the L-shaped plate 32 to avoid movement interference between the two.

[0027] According to the above structure, when a leak occurs, the sealing gasket 35 will be lifted by the leaking water flow, thereby causing the arc-shaped clamp 34 to move. The movement of the arc-shaped clamp 34 causes the long rod 41 to move, and the movement of the long rod 41 causes the protruding rod 42 to move. During the movement of the protruding rod 42, it comes into contact with the alarm 43, and the alarm 43 controls the warning light 44 to start working. The operation of the warning light 44 makes it easier for staff to find out which connection is leaking, saving staff time from searching for the connection and improving maintenance efficiency. The warning light 44 can issue a warning when the equipment is abnormal, reminding staff to take measures to prevent accidents. The warning light 44 can issue an early warning to prevent the problem from spreading or worsening, and timely maintenance and repair can be carried out, thereby extending the service life of the equipment and reducing losses caused by equipment damage.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
