[0002] Sewer pipes are an important part of the drainage system of buildings or cities. They are mainly responsible for receiving, transporting and treating various liquid and solid substances such as wastewater, sewage, rainwater, etc. Through reasonable design and layout, they discharge indoor and outdoor wastewater and sewage to sewage treatment plants or discharge outlets for treatment, thus ensuring environmental hygiene and human health.

[0003] Among them, the existing pipes with a diameter equal to or greater than 100mm and the pipes with a diameter greater than 50mm in the fire water supply system are mostly connected by metal grooved connectors, which can firmly fix the pipes and support their weight, forming an annular support structure around the pipes, thereby ensuring the stability and safety of the pipes, and can effectively reduce pipe vibration and noise, thereby improving the durability and performance of the pipes.

[0004] However, the pipelines are exposed all year round. Over time, the pipeline body will show varying degrees of oxidation, especially the pipe joints are more prone to leakage, affecting the normal operation of sewage discharge. Long-term water seepage at the pipe joints may also accelerate the aging of metal groove connectors, thus posing great safety hazards. At the same time, the construction and placement of pipelines and grooved connectors use a relatively messy range of brands and manufacturers, and the specifications of some pipelines and grooved connectors cannot be fully matched, increasing the risk of leakage. Utility Model Content

[0008] The waterproof part includes a sealing gasket arranged in the labyrinth waterproof groove and matching the shape of the protective cover, and the sealing gasket includes skirt parts provided at both ends of the protective cover and a textured surface composed of multiple waterproof ribs located between the two skirt parts.

[0009] In one embodiment, the side of the protective sleeve facing the tube body includes an arc-shaped upper edge and an arc-shaped lower edge located below the upper edge.

[0010] In one embodiment, the labyrinth waterproof groove is arranged on the upper edge and the lower edge surface.

[0011] In one embodiment, both ends of the protective sleeve are provided with connecting ears extending out of the protective sleeve for connecting two protective sleeves.

[0012] In one embodiment, a plurality of screw holes are provided on the connecting ear.

[0014] In one embodiment, the skirt portion is embedded in the skirt groove.

[0015] In one embodiment, the skirt groove is connected to the labyrinth waterproof groove to form an integral body.

[0016] In one embodiment, a protrusion matching the shape of the labyrinth waterproof groove is provided on a side of the sealing gasket facing the protective cover.

[0017] In one embodiment, the textured surface includes at least three waterproof ribs.

[0018] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0019] By arranging two relatively connected protective covers on the outer circumference of the pipeline to be protected and the pipeline connector, the pipeline connection can be protected from the outside, the natural aging of the pipeline connection and the pipeline connector can be delayed, the service life can be extended, and the pipeline can be waterproofed and sealed for the second time.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a pipe joint protection device, which can solve the technical problems in the prior art that the pipe and the pipe connector are not well matched and the pipe joint connection is prone to aging and water seepage after the pipe is used for a long time.

[0029] Figure 1 Schematic diagram of a pipe joint protection device provided in an embodiment of the present application. Figure 1 As shown, the pipe joint protection device provided by the present application includes a shell part and a waterproof part, the shell part includes two protective covers 1 for being connected in opposite directions to wrap the outer periphery of the pipe joint to be protected, and the surface of the protective cover 1 protrudes outward to form an accommodating space 101 for accommodating the connecting parts between the pipe joints to be protected, and the inner edge surface of the protective cover 1 is provided with a labyrinth waterproof groove 2; the waterproof part includes a sealing gasket 3 arranged in the labyrinth waterproof groove 2 and matching the shape of the protective cover 1, and the sealing gasket 3 includes a skirt part 301 provided at both ends of the protective cover 1 and a textured surface 302 composed of multiple waterproof ribs located between the two skirt parts 301.

[0030] The shell part is arranged horizontally at the pipe connection, and is formed by two protective sleeves 1 connected relative to each other and wrapped around the pipe connection piece. The existing commonly used pipes are all cylindrical. Therefore, in one embodiment of the present application, the protective sleeve 1 is a semicircular shell with a certain height, and the height here needs to exceed the height of the pipe connection piece. The protective sleeve 1 has an arc surface away from the pipe to be protected and a plane facing the pipe to be protected. When connected, the two planes are relatively connected to form a complete annular shell part. The pipe connection piece is arranged at the outer periphery of the pipe connection piece, which itself has a certain thickness, and the existing pipe connection pieces are mostly connected by two semicircular metal clamps connected by bolts, and the bolt connection piece protrudes outward by a certain height. Therefore, in the present application, a accommodating space 101 with the same height as the protruding part of the pipe connection piece is arranged on the outer surface of the middle position of the arc of the protective sleeve 1, which is used to accommodate the protruding part of the pipe connection piece.

[0031] Furthermore, the material of the protective cover 1 includes but is not limited to PE and PA materials. In one embodiment of the present application, the protective cover 1 is made of a transparent material. The protective cover 1 is wrapped around the outer periphery of the groove connector. Its transparent nature can clearly observe the leakage of the pipe connector and the pipe to be protected, making it convenient to handle and repair the leakage in a timely manner.

[0032] The sealing gasket 3 is arranged inside the protective cover 1 and is engaged with the labyrinth waterproof groove 2. Its shape is consistent with that of the protective cover 1. The cross-section of a single sealing gasket 3 is also semicircular. The inner surface of the sealing gasket 3 is directly in contact with the pipe body of the pipe to be protected. The side view of the sealing gasket 3 is a rectangular frame, and the middle part is hollowed out for the pipe connector to pass through. The liquid leaking from the pipe connector will be blocked by the sealing gasket 3 to improve the sealing effect. At the same time, the sealing gasket 3 is made of rubber, which not only has a high friction coefficient and good sealing performance, but also has high ozone resistance, heat resistance and weather resistance, and good low-temperature flexibility. It can be used in ozone-resistant, weather-resistant and UV-resistant occasions.

[0033] The skirt portions 301 are arranged at both ends of the sealing gasket 3. The sealing gasket 3 also includes an arc surface away from the pipe to be protected and a plane facing the pipe to be protected. Taking the example where the plane of the sealing gasket 3 faces the right side and the arc surface faces the left side, the right side view of the sealing gasket 3 is a rectangular frame, and the skirt portions 301 are vertically arranged on the left and right sides of the frame, and the two skirt portions 301 extend a certain length in a direction away from each other.

[0034] Furthermore, the side of the sealing gasket 3 facing the protective cover 1 is arranged in the labyrinth waterproof groove 2, and the side of the sealing gasket 3 facing the pipe to be protected is provided with a textured surface 302. The liquid seeping from the pipe to be protected directly contacts the textured surface 302. When the leaking water flows through the textured surface 302, friction is generated due to viscosity and inertia, resulting in a slow flow rate, thereby reducing the leakage amount.

[0035] Furthermore, Figure 2A schematic diagram of the protective cover structure in a pipe joint protection device provided in an embodiment of the present application, wherein the side of the protective cover 1 facing the pipe body includes an arcuate upper edge 103 and an arcuate lower edge 104 located below the upper edge 103, and a labyrinth waterproof groove 2 is arranged on the surface of the upper edge 103 and the lower edge 104. Taking the protective cover 1 with the plane facing the right arc surface to the left as an example, its right view is a rectangle, and the top and bottom sides of the rectangle are the upper edge 103 and the lower edge 104 of the protective cover 1.

[0036] Furthermore, both ends of the protective cover 1 are provided with connecting ears 4 extending out of the protective cover 1 for connecting the two protective covers 1. Taking the protective cover 1 with the plane facing the right arc surface facing the left as an example, its right view is a rectangle, and the connecting ears 4 are vertically arranged on the left and right sides of the rectangle, respectively, and the height of the connecting ears 4 is equal to the height of the protective cover 1, so as to improve the waterproof and sealing effect.

[0037] Furthermore, a plurality of screw holes 402 are provided on the connecting ear 4. When using the pipe joint protection device in the present application, first select a protective cover 1 of suitable specifications according to the diameter of the pipe to be protected, then place the two protective covers 1 at the connection of the pipe joints of the pipe to be protected, and wrap the pipe connector, and then connect the connecting ears 4 on the two protective covers 1 respectively. If leakage of the pipe is found later, the protective cover 1 needs to be removed for maintenance. Therefore, in the present application, in order to facilitate the later disassembly and maintenance work, the two protective covers 1 are connected by bolts.

[0038] Figure 5 A schematic diagram of the use status of a pipe joint protection device provided in an embodiment of the present application. In the present application, every two mutually matching protective sleeves 1 form a group. In one embodiment of the present application, for a straight-through pipe, a group of protective sleeves 1 can be directly arranged horizontally at the pipe connection. At this time, there are three screw holes 402 on each connecting ear 4, which are respectively arranged at the top, middle and tail of the connecting ear 4. For an elbow pipe, two groups of protective sleeves 1 are required to be respectively arranged at the pipe connections at both ends of the elbow pipe. At this time, the two groups of protective sleeves 1 are arranged vertically. The connecting ears 4 on the side where the two groups of protective sleeves 1 are close to each other may cause interference. Therefore, in another embodiment of the present application, the connecting ear 4 is eccentrically designed. Figure 3 A schematic structural diagram of a second implementation manner of a connecting ear 4 in a pipe joint protection device provided in an embodiment of the present application, wherein at least one of the two corners of the connecting ear 4 away from the skirt groove 401 is set as a chamfer 403, and when connecting the elbow pipe, the two connecting ears 4 are provided with sides with the chamfer 403 facing each other. At the same time, in the second implementation manner, the number of screw holes 402 on the connecting ear 4 needs to be reduced, but is at least 1.

[0039] Furthermore, a skirt groove 401 is provided on the surface of the connecting ear 4 on one side facing the pipe body of the pipe section to be protected, and the skirt portion 301 is embedded in the skirt groove 401. The connecting ear 4 is mainly the connection between the two protective sleeves 1. To facilitate later disassembly and repair, the two connecting ears 4 are detachably connected. Therefore, a gap will inevitably appear between the two connecting ears 4, and the skirt portion 301 can fill the connection gap between the two connecting ears 4. In one embodiment of the present application, the thickness of the connecting ear 4 is slightly larger than the height of the skirt groove 401, so that when the two protective sleeves 1 are connected, the skirt portion 301 is squeezed to improve the overall anti-leakage effect. At the same time, the lateral width of the skirt groove 401 is narrower than the lateral width of the connecting ear 4, and the minimum difference in the lateral width of the skirt groove 401 and the connecting ear 4 should be greater than the diameter of the screw hole 402, so as to reserve an area for setting the screw hole 402 on the outside of the connecting ear 4.

[0040] Furthermore, the skirt groove 401 is connected with the labyrinth waterproof groove 2 to form a whole. After the skirt groove 401 and the labyrinth waterproof groove 2 are connected, they are consistent with the contour of the sealing gasket 3. The sealing gasket 3 is placed in the skirt groove 401 and the labyrinth waterproof groove 2 to limit the sealing gasket 3.

[0041] Further, Figure 4 An enlarged view of the details of the sealing gasket in a pipe joint protection device provided in an embodiment of the present application is provided. The side of the sealing gasket 3 facing the protective sleeve 1 is provided with a protrusion 303 matching the shape of the labyrinth waterproof groove 2. The labyrinth waterproof groove 2 has a plurality of interconnected grooves, and the characteristics of the labyrinth structure are used to achieve leakage prevention. In actual use, it is combined with a sealant, combined with the reasonable application of fluid dynamics effects, sealing structure and design, and effective functions to form a multi-faceted comprehensive leakage prevention system, and the side of the sealing gasket 3 in contact with the labyrinth waterproof groove 2 is provided with a protrusion 303 consistent with the groove body of the labyrinth waterproof groove 2, which is convenient for embedding in the labyrinth waterproof groove 2 and can also improve the waterproof effect. Labyrinth waterproofing is a commonly used waterproofing method in this technical field and will not be described in detail here.

[0042] Furthermore, the textured surface 302 includes at least three waterproof ribs, and the textured surface 302 is arranged on the side of the sealing gasket 3 that contacts the pipe body to be protected. Multiple waterproof ribs can be arranged in parallel or in a labyrinth waterproof style. There is no specific limitation in the present application.

[0043] When using the pipe joint protection device in the present application, first select a protective cover 1 of appropriate specifications according to the diameter of the pipe to be protected and the type of pipe, then place the protective cover 1 at the installation position and connect it into place through the connecting ear 4. The pipe joint protection device in the present application can provide secondary protection for the pipe to be protected and the pipe connector, and slow down the aging time of the pipe and the pipe connector. At the same time, for the situation where the pipe and the pipe connector are not well matched, the protective cover 1 can provide a certain reinforcement from the outside, and can also perform secondary sealing on the pipe leakage to prevent liquid seepage. The transparent nature of the protective cover 1 can directly observe the internal leakage for timely maintenance.
