Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, specifically a quick sealing device for rainwater and sewage pipelines. Background Technology

[0002] Sewage pipeline systems consist of pipelines and ancillary structures that collect and transport urban sewage. They are closely related to people's lives. Currently, in urban pipeline projects involving municipal rerouting and emergency repairs, pressurized sealing operations are often required on operating pipelines to minimize adverse impacts on downstream users. Traditional sewage pipeline sealing methods often use simple materials such as sandbags and cement for temporary sealing. This method is not only inefficient but also has unstable sealing effects and is prone to sewage leakage, which seriously affects the environment and residents' lives. Utility Model Content

[0003] The purpose of this invention is to provide a quick sealing device for rainwater and sewage pipes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick sealing device for rainwater and sewage pipes, comprising a sealing component and a fixing component;

[0005] The sealing assembly includes an installation plate, a base on one side of the installation plate, a lead screw rotatably mounted in the middle of the installation plate and the base, a slider threaded onto the surface of the lead screw, a support plate fixedly mounted on one side of the slider, flexible rubber sleeves symmetrically connected to the inner sides of the support plate and the base, a sealing ring installed between the two flexible rubber sleeves, and a rocker wheel fixedly mounted on one end of the lead screw.

[0006] The fixing assembly includes support plates fixedly installed on both sides of the surface of the mounting plate. The surface of the support plates is threaded with screws. One end of the screw is equipped with a rotating knob, and the other end of the screw is fixedly equipped with a fixing ring.

[0007] As a preferred embodiment of the present invention: a plurality of first inner support bars are hinged around the surface of the support plate, a plurality of second inner support bars are hinged around the surface of the base, a support ring is installed on the inner wall of the sealing ring, and one end of each of the first and second inner support bars is hinged to both sides of the support ring.

[0008] As a preferred embodiment of this utility model: a limiting rod is fixedly installed on the surface of the mounting plate and the base, and the support plate is slidably installed on the surface of the limiting rod.

[0009] As a preferred embodiment of this utility model, the surface of the fixing ring is provided with anti-slip texture.

[0010] As a preferred embodiment of this utility model, a conical head is fixedly installed at the front end of the base.

[0011] As a preferred embodiment of this utility model, both the lead screw and the screw rod are coated with an anti-corrosion layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) A lead screw is rotatably installed in the middle of the mounting plate and the base. A rocker wheel is installed at one end of the lead screw. By rotating the rocker wheel, the lead screw is driven to rotate. The rotation of the lead screw causes the slider connected to the surface thread to rotate as well. Since a support plate is connected to one side of the slider, the support plate slides on the surface of the limit rod. When the lead screw rotates, the slider moves closer to the base along the lead screw. The slider moves closer to the base, causing the flexible rubber sleeves that are symmetrically connected on the surfaces of the two to arch up. This causes the sealing ring between the two flexible rubber sleeves to fit against the inner wall of the rainwater and sewage pipe. The expansion of the sealing ring is adjusted by sliding the slider to meet the sealing requirements of pipes of different diameters. The sealing ring has a good sealing effect and prevents rainwater leakage.

[0014] (2) With the provided fixing components, support plates are installed on both sides of the surface of the mounting plate. The surface of the support plate is threaded with a screw. Rotating the rotating knob at one end of the screw causes the screw to move on the surface of the support plate. The movement of the screw causes the fixing ring installed at the other end to move closer to the inner wall of the pipe, so that the mounting plate is fixed to the inner wall of the rainwater pipe through the fixing ring, thereby fixing the sealing device inside the rainwater pipe.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 - Figure 4 A quick sealing device for rainwater and sewage pipes includes: a sealing component 1 and a fixing component 2;

[0024] Please see Figure 1 , Figure 3 The sealing assembly 1 includes a mounting plate 101, a base 102 on one side of the mounting plate 101, a lead screw 103 rotatably mounted in the middle of the mounting plate 101 and the base 102, a slider 104 threadedly connected to the surface of the lead screw 103, a support plate 105 fixedly mounted on one side of the slider 104, flexible rubber sleeves 106 symmetrically connected to the inner sides of the support plate 105 and the base 102, a sealing ring 107 installed between the two flexible rubber sleeves 106, a rocker wheel 108 fixedly mounted on one end of the lead screw 103, a limit rod 6 fixedly mounted on the surface of the mounting plate 101 and the base 102, and the support plate 105 slidably mounted on the surface of the limit rod 6.

[0025] In practical use: A lead screw 103 is rotatably mounted in the middle of the mounting plate 101 and the base 102. A rocker wheel 108 is mounted on one end of the lead screw 103. Rotating the rocker wheel 108 drives the lead screw 103 to rotate. The rotation of the lead screw 103 causes the slider 104, which is threaded on the surface, to rotate as well. Since a support plate 105 is connected to one side of the slider 104, and the support plate 105 slides on the surface of the limit rod 6, the slider 104 moves closer to the base 102 along the lead screw 103 when the lead screw 103 rotates. The slider 104 moves closer to the base 102, causing the flexible rubber sleeves 106, which are symmetrically connected on the surfaces of the two, to arch up. This causes the sealing ring 107 between the two flexible rubber sleeves 106 to fit against the inner wall of the rainwater and sewage pipe. The expansion of the sealing ring 107 can be adjusted by sliding the slider 104 to meet the sealing needs of pipes of different diameters. The sealing ring 107 provides a good sealing effect and prevents rainwater leakage.

[0026] Please see Figure 1 , Figure 4The fixing component 2 includes a support plate 201 fixedly installed on both sides of the surface of the mounting plate 101. The surface of the support plate 201 is threaded with a screw 202. One end of the screw 202 is equipped with a rotating knob 203, and the other end of the screw 202 is fixedly equipped with a retaining ring 204.

[0027] In practical use: Support plates 201 are installed on both sides of the surface of the mounting plate 101. A screw 202 is threadedly connected to the surface of the support plate 201. Rotating the rotation knob 203 at one end of the screw 202 causes the screw 202 to move on the surface of the support plate 201. The movement of the screw 202 causes the fixing ring 204 installed at the other end to move closer to the inner wall of the pipe, so that the mounting plate 101 is fixed to the inner wall of the rainwater pipe by the fixing ring 204, thereby fixing the sealing device inside the rainwater pipe.

[0028] Please see Figure 3 The surface of the support plate 105 is hinged with several first inner support bars 3, the surface of the base 102 is hinged with several second inner support bars 4, and the inner wall of the sealing ring 107 is fitted with a support ring 5. One end of each of the first inner support bars 3 and the second inner support bars 4 is hinged to both sides of the support ring 5.

[0029] In practical use: a number of first inner support bars 3 are hinged around the surface of the support plate 105, and a number of second inner support bars 4 are hinged around the surface of the base 102. One end of each of the first inner support bars 3 and the second inner support bars 4 is hinged to both sides of the support ring 5 installed on the inner wall of the sealing ring 107. When the slider 104 slides, it causes the first inner support bars 3 and the second inner support bars 4 to expand relative to the support ring 5, thereby supporting the expanded flexible rubber sleeve 106 and preventing excessive water pressure from deforming the flexible rubber sleeve 106 and causing leakage.

[0030] Please see Figure 4 The surface of the fixing ring 204 is provided with anti-slip texture 7.

[0031] In practical use: the surface of the fixing ring 204 is provided with anti-slip texture 7, which can increase the friction with the inner wall of the pipe and improve stability.

[0032] Please see Figure 2 A conical head 8 is fixedly installed at the front end of the base 102.

[0033] In practical use: A conical head 8 is installed at the front end of the base 102. When the device is inserted into the pipe, the conical head 8 can disperse the water pressure and prevent the pressure from being too high when the base 102 is pushed into the inner wall of the drain pipe.

[0034] Please see Figure 3 , Figure 4 Both the lead screw 103 and the screw 202 are coated with an anti-corrosion layer.

[0035] In practical use: both the lead screw 103 and the screw 202 are coated with an anti-corrosion layer, which gives the structural components good corrosion resistance.

[0036] A lead screw 103 is rotatably mounted in the middle of the mounting plate 101 and the base 102. A rocker wheel 108 is mounted on one end of the lead screw 103. Rotating the rocker wheel 108 drives the lead screw 103 to rotate. The rotation of the lead screw 103 causes the slider 104, which is threaded on the surface, to rotate as well. Since a support plate 105 is connected to one side of the slider 104, and the support plate 105 slides on the surface of the limit rod 6, the slider 104 moves closer to the base 102 along the lead screw 103 when the lead screw 103 rotates. The slider 104 moves closer to the base 102, causing the flexible rubber sleeves 106, which are symmetrically connected on the surfaces of the two to arch. This causes the sealing ring 107 between the two flexible rubber sleeves 106 to fit against the inner wall of the rainwater and sewage pipe. The expansion of the sealing ring 107 can be adjusted by sliding the slider 104 to meet the sealing needs of pipes of different diameters. The sealing ring 107 provides a good sealing effect and prevents rainwater leakage.
