Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage pipeline connection technology, and in particular to a seepage prevention device for water supply and drainage pipes in building engineering. Background Technology
[0002] Building construction refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among these, the installation of water supply and drainage pipes is an important component of building construction.
[0003] Existing water supply and drainage pipes are generally connected by welding or flanges. During water transportation, the large water pressure can cause the pipes to vibrate, which can affect the seal between pipe connections and cause leakage. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a seepage prevention device for water supply and drainage pipes in building engineering.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seepage prevention device for water supply and drainage pipes in building engineering, comprising a first pipe, a second pipe, and a U-shaped seat. An auxiliary device is provided on the outer wall surface of the first pipe, the auxiliary device including a slip ring. The slip ring is slidably connected to the outer wall surface of the first pipe, and a sealing ring is fixedly installed on the surface of the slip ring. A fixing ring is fixedly installed on the outer wall surface of the second pipe, and a sealing groove is formed on the surface of the fixing ring. The sealing ring and sealing groove enhance the sealing performance at the connection between the first and second pipes.
[0006] Preferably, a U-shaped rod is fixedly installed on the annular sidewall of the fixing ring, and two sliders are slidably connected to the surface of the U-shaped rod. A spring is fixedly installed between the two sliders. The spring serves to limit the position of the sliders on the surface of the U-shaped rod.
[0007] Preferably, both sliders have hinge plates hinged to their bottom surfaces, and a lifting plate is hinged to the end of each hinge plate away from the slider. The hinge plates enable the sliders to move along the surface of the U-shaped rod.
[0008] Preferably, a positioning rod is fixedly installed on the bottom surface of the lifting plate, and an L-shaped plate is fixedly installed on the annular sidewall of the slip ring. A positioning hole is formed on the horizontal end surface of the L-shaped plate. The positioning rod and positioning hole effectively limit the first pipe to be positioned inside the second pipe.
[0009] Preferably, the annular sidewall of the fixed ring is provided with a rotating device, which includes a socket fixedly installed on the annular sidewall of the fixed ring. A rotating shaft is rotatably connected between the two inner walls of the U-shaped seat. A rotating plate is fixedly installed on the outer surface of the rotating shaft, with one end of the rotating plate located inside the socket. A motor is fixedly installed on one side surface of the U-shaped seat, and the output end of the motor is fixedly connected to the rotating shaft. The motor effectively drives the rotating shaft to rotate.
[0010] Preferably, a U-shaped frame is fixedly mounted on the surface of the rotating plate, and a threaded rod is rotatably connected between the inner walls of both ends of the U-shaped frame. A rotating wheel is fixedly mounted on one end of the threaded rod. The rotating wheel drives the threaded rod to rotate.
[0011] Preferably, the inner wall surface of the horizontal end of the U-shaped frame has a groove, the surface of the threaded rod is threadedly connected to a movable plate, the surface of the movable plate is fixedly mounted with a plug rod, and the surface of the socket has a socket hole. The plug rod and socket hole effectively limit the rotating plate to be positioned inside the socket.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting an auxiliary device, when it is necessary to connect the first pipe and the second pipe, firstly, the lifting plate is raised upwards. The upward movement of the lifting plate drives the hinge plate to move. The movement of the hinge plate pushes the two sliders on the surface of the U-shaped rod to move away from each other. The movement of the two sliders on the surface of the U-shaped rod away from each other will cause the spring to stretch. At the same time, the upward movement of the lifting plate also drives the positioning rod to move. When the positioning rod moves to the appropriate position, the second pipe is inserted into the interior of the first pipe. Then, the sliding ring is slid, causing the sliding ring to move on the outer wall surface of the first pipe. The movement of the sliding ring on the outer wall of the first pipe drives the sealing ring to move. The movement of the sealing ring causes it to enter the solid state. Inside the sealing groove on the surface of the fixed ring, the movement of the slip ring also drives the L-shaped plate to move. When the L-shaped plate moves to a position where the positioning hole on its surface is directly below the positioning rod, the lifting plate is released, and the spring's rebound force resets the positioning rod. The reset positioning rod then inserts itself into the positioning hole, and the positioning rod and positioning hole are connected, thus firmly confining the sealing ring inside the sealing groove. At the same time, the second pipe is also confined inside the first pipe. Through the cooperation of the above structures, the installation stability between the pipes is improved, and the setting of the sealing ring and sealing groove also improves the sealing performance at the connection between the first and second pipes, thereby preventing leakage and other situations from occurring.
[0014] 2. In this utility model, by setting a rotating device, when it is necessary to clean as much debris as possible from the inner walls of the first and second pipes, the rotating plate is first inserted into the socket. Then, the rotating wheel is rotated, which drives the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move inside the groove. The movement of the movable plate inside the groove drives the insertion rod to move, and the insertion rod moves so that it inserts itself into the socket. The insertion rod and the socket are connected, thereby limiting the rotating plate inside the socket. Then, the motor is started, which drives the rotating shaft to rotate. The rotation of the rotating shaft drives the rotating plate to rotate, and the rotation of the rotating plate ultimately drives the first and second pipes to rotate. When the first and second pipes rotate to the appropriate tilt angle, the motor can be turned off. Then, in conjunction with the water flow during the use of the first and second pipes, as well as the inertia of the debris inside the first and second pipes, it helps to detach the accumulated debris from the inner walls of the first and second pipes. Through the cooperation of the above structure, the problem of a large amount of debris adhering to the inner walls of existing building water supply and drainage pipes after long-term use is solved. If not cleaned in time, it will lead to a significant reduction in the drainage capacity of the pipes. If the inner walls of the pipes are blocked by a large amount of deposits, it will also lead to the danger of pipe bursting. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a seepage prevention device for water supply and drainage pipes in building engineering, including a first pipe 1, a second pipe 2 and a U-shaped seat 5.
[0024] The specific setup and function of its auxiliary device 3 and rotating device 4 will be described in detail below.
[0025] In this embodiment: the outer wall surface of the first pipe 1 is provided with an auxiliary device 3, the auxiliary device 3 includes a slip ring 301, the slip ring 301 is slidably connected to the outer wall surface of the first pipe 1, a sealing ring 302 is fixedly installed on the surface of the slip ring 301, and a fixing ring 303 is fixedly installed on the outer wall surface of the second pipe 2, and a sealing groove 304 is opened on the surface of the fixing ring 303.
[0026] In this embodiment, the sealing ring 302 and the sealing groove 304 are provided to increase the sealing performance at the connection between the first pipe 1 and the second pipe 2.
[0027] Specifically, a U-shaped rod 305 is fixedly installed on the annular sidewall of the fixed ring 303, and two sliders 306 are slidably connected to the surface of the U-shaped rod 305. A spring 307 is fixedly installed between the two sliders 306.
[0028] In this embodiment, the spring 307 serves to limit the position of the slider 306 on the surface of the U-shaped rod 305.
[0029] Specifically, hinge plates 308 are hinged to the bottom surfaces of both sliders 306, and a lifting plate 309 is hinged to the end of the hinge plate 308 away from the slider 306. The hinge plates 308 are designed to move the sliders 306 on the surface of the U-shaped rod 305.
[0030] Specifically, a positioning rod 310 is fixedly installed on the bottom surface of the lifting plate 309, and an L-shaped plate 311 is fixedly installed on the annular sidewall of the slip ring 301. A positioning hole 312 is provided on the horizontal end surface of the L-shaped plate 311. The positioning rod 310 and the positioning hole 312 serve to limit the first pipe 1 to be confined inside the second pipe 2.
[0031] In this embodiment: the annular sidewall of the fixed ring 303 is provided with a rotating device 4, the rotating device 4 includes a socket 401, the socket 401 is fixedly installed on the annular sidewall of the fixed ring 303, a rotating shaft 402 is rotatably connected between the inner walls of the two sides of the U-shaped seat 5, a rotating plate 403 is fixedly installed on the outer surface of the rotating shaft 402, one end of the rotating plate 403 is located inside the socket 401, a motor 404 is fixedly installed on one side surface of the U-shaped seat 5, and the output end of the motor 404 is fixedly connected to the rotating shaft 402. When it is necessary to clean as much debris as possible from the inner walls of the first pipe 1 and the second pipe 2, first insert the rotating plate 403 into the socket 401, then rotate the rotating wheel 407. The rotation of the rotating wheel 407 drives the threaded rod 406 to rotate, which in turn drives the movable plate 409 to move inside the groove 408. The movement of the movable plate 409 in the groove 408 drives the insertion rod 410 to move, which then inserts itself into the socket 411. The insertion rod 410 and the socket 411 are engaged, thus limiting the rotating plate 403 inside the socket 401. Next, start the motor 404. The motor 404 starts and drives the rotating shaft 402 to rotate, which in turn drives the rotating plate 403 to rotate. The rotation of motor 403 ultimately drives the first pipe 1 and the second pipe 2 to rotate. When the first pipe 1 and the second pipe 2 rotate to a suitable tilt angle, motor 404 can be turned off. Then, in conjunction with the water flow during the use of the first pipe 1 and the second pipe 2, as well as the inertia of the debris in the first pipe 1 and the second pipe 2, it helps to detach the debris accumulated in the first pipe 1 and the second pipe 2 from their inner walls. Through the cooperation of the above structure, the problem of a large amount of debris adhering to the inner wall of existing building water supply and drainage pipes after long-term use is solved. If it is not cleaned in time, it will lead to a significant reduction in the drainage capacity of the pipe. If the inner wall of the pipe is blocked by a large amount of deposits, it will also lead to the danger of pipe bursting.
[0032] Specifically, a U-shaped frame 405 is fixedly installed on the surface of the rotating plate 403, and a threaded rod 406 is rotatably connected between the inner walls of the two ends of the U-shaped frame 405. A rotating wheel 407 is fixedly installed at one end of the threaded rod 406.
[0033] In this embodiment, the rotating wheel 407 serves to drive the threaded rod 406 to rotate.
[0034] Specifically, the inner wall surface of the horizontal end of the U-shaped frame 405 has a groove 408, the surface of the threaded rod 406 is threadedly connected to a movable plate 409, the surface of the movable plate 409 is fixedly installed with a plug rod 410, and the surface of the socket 401 has a plug hole 411.
[0035] In this embodiment, the insertion rod 410 and the insertion hole 411 serve to limit the rotating plate 403 inside the socket 401.
[0036] Working principle: By setting auxiliary device 3, when it is necessary to connect the first pipe 1 and the second pipe 2, the lifting plate 309 is first raised upward. The upward movement of the lifting plate 309 drives the hinge plate 308 to move. The movement of the hinge plate 308 pushes the two sliders 306 to move away from each other on the surface of the U-shaped rod 305. The movement of the two sliders 306 away from each other on the surface of the U-shaped rod 305 will cause the spring 307 to stretch. At the same time, the upward movement of the lifting plate 309 also drives the positioning rod 310 to move. When the positioning rod 310 moves to the appropriate position, the second pipe 2 is inserted into the interior of the first pipe 1. Then, the sliding ring 301 is slid, causing the sliding ring 301 to move on the outer wall surface of the first pipe 1. The movement of the sliding ring 301 on the outer wall of the first pipe 1 drives the sealing ring 302 to move. The movement of the sealing ring 302 causes it to enter the fixing ring. Inside the sealing groove 304 on the surface of 303, the movement of the slip ring 301 also drives the L-shaped plate 311 to move. When the L-shaped plate 311 moves to a position where the positioning hole 312 on its surface is directly below the positioning rod 310, the lifting plate 309 is released, and the spring force of the spring 307 is used to reset the positioning rod 310. The reset positioning rod 310 then inserts itself into the positioning hole 312. The positioning rod 310 and the positioning hole 312 are connected, thereby firmly restricting the sealing ring 302 inside the sealing groove 304. At the same time, the second pipe 2 is also restricted inside the first pipe 1. Through the cooperation of the above structures, the installation stability between the pipes is improved. The setting of the sealing ring 302 and the sealing groove 304 also improves the sealing performance at the connection between the first pipe 1 and the second pipe 2, thereby preventing leakage and other situations.When it is necessary to clean as much debris as possible from the inner walls of the first pipe 1 and the second pipe 2, first insert the rotating plate 403 into the socket 401, then rotate the rotating wheel 407. The rotation of the rotating wheel 407 drives the threaded rod 406 to rotate, which in turn drives the movable plate 409 to move inside the groove 408. The movement of the movable plate 409 in the groove 408 drives the insertion rod 410 to move, which then inserts itself into the socket 411. The insertion rod 410 and the socket 411 are engaged, thus limiting the rotating plate 403 inside the socket 401. Next, start the motor 404. The motor 404 starts and drives the rotating shaft 402 to rotate, which in turn drives the rotating plate 403 to rotate. The rotation of motor 403 ultimately drives the first pipe 1 and the second pipe 2 to rotate. When the first pipe 1 and the second pipe 2 rotate to a suitable tilt angle, motor 404 can be turned off. Then, in conjunction with the water flow during the use of the first pipe 1 and the second pipe 2, as well as the inertia of the debris in the first pipe 1 and the second pipe 2, it helps to detach the debris accumulated in the first pipe 1 and the second pipe 2 from their inner walls. Through the cooperation of the above structure, the problem of a large amount of debris adhering to the inner wall of existing building water supply and drainage pipes after long-term use is solved. If it is not cleaned in time, it will lead to a significant reduction in the drainage capacity of the pipe. If the inner wall of the pipe is blocked by a large amount of deposits, it will also lead to the danger of pipe bursting.
