Description

Technical Field

[0001] The invention relates to the technical field of inspection wells, in particular to an I-shaped sealing rubber ring for a drainage inspection well. Background Art

[0002] At present, when the drainage pipe is connected to the inspection well, a hole larger than the outer diameter of the drainage pipe is generally reserved at the mouth of the inspection well. After the pipe is inserted, concrete is poured around the pipe to ensure the stability and sealing of the connection between the pipe and the inspection well. However, in actual construction, due to construction quality problems, the connection between the drainage pipe and the inspection well is a rigid connection, and the uneven settlement of the inspection well and the drainage pipe, the interface will be torn or broken, resulting in water leakage between the drainage pipe and the inspection well, thereby polluting the groundwater environment.

[0003] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands.

[0004] A rubber ring is installed on the outer wall of the drain pipe. Since the rubber ring is made of flexible material, it can play a good coordination role when the inspection well and the drainage pipe settle unevenly. In addition, due to the expansion effect of the rubber ring, the connection between the drainage pipe and the inspection well can be made more airtight, ensuring that there is no water leakage between the drainage pipe and the inspection well. Summary of the invention

[0005] The purpose of the present invention is to provide an I-shaped sealing rubber ring for a drainage inspection well, so as to solve the existing problem that uneven settlement of the inspection well and the drainage pipe will cause cracks or ruptures at the interface, resulting in water leakage between the drainage pipe and the inspection well, thereby causing pollution to the groundwater environment.

[0006] To achieve the above-mentioned purpose, the present invention provides an I-shaped sealing rubber ring for a drainage inspection well, comprising an inspection well, a drainage pipe, and an inspection well base. The bottom of the inspection well is located on the inspection well base, and drainage pipes are arranged on the side walls on both sides of the inspection well. An anti-corrosion layer is arranged on the outer wall of the drainage pipe, and a drainage pipe mounting hole is arranged on the side wall of the inspection well. One end of the drainage pipe is connected to the mounting hole through cement mortar, and a rubber ring is sleeved on the outer side of one end of the drainage pipe located at the mounting hole. The rubber ring is I-shaped, and the inner diameter of the rubber ring is consistent with the outer diameter of the drainage pipe, and its thickness is 200 mm greater than the thickness of the inspection well wall. The rubber ring comprises an extended edge and a ring body, and an installation groove is arranged inside the ring body. A sealing assembly is arranged in the installation groove, and the sealing assembly comprises a first push rod, a second push rod, a first movable rod, a second movable rod, a spring, a first support plate, and a second support plate.

[0007] Preferably, the extended edges are respectively located at the top and bottom of the ring body and extend toward the outside of the ring body.

[0008] Preferably, the mounting grooves are distributed along the circumference of the inner part of the ring body to form a ring.

[0009] Preferably, the sealing assembly is provided in plurality and is evenly spaced along the circumference of the mounting groove inside the ring body.

[0010] Preferably, one end of the first movable rod is obliquely connected to one end of the first push rod, and one end of the second movable rod is obliquely connected to one end of the second push rod. The other ends of the first push rod and the second push rod respectively pass through the side walls of the mounting groove and are in sliding contact with the side walls of the mounting groove. A spring is provided between the first movable rod and the second movable rod, one end of the spring is connected to the inner side wall of the first movable rod, and the other end of the spring is connected to the inner side wall of the second movable rod. A fixing rod is provided at the bottom of the mounting groove, and the other ends of the first movable rod and the second movable rod are respectively rotatably connected to the fixing rod, and the fixing rods are distributed in a ring shape in the mounting groove.

[0011] Preferably, the first push rod passes through the first support plate, the second push rod passes through the second support plate, and the side surfaces of the first support plate and the second support plate are in contact with the inner wall surface of the installation groove respectively.

[0012] Preferably, a sliding seat is provided on the inner side surface of the first movable rod, and a sliding rod is provided on the inner side surface of the second movable rod. The sliding rod slides in the sliding seat, one end of the sliding seat is fixedly connected to the first movable rod, and one end of the sliding rod is rotatably connected to the second movable rod.

[0013] Preferably, a limiting groove is provided at one end of the slide away from the first movable rod, and an arc-shaped slide is provided at one end of the limiting groove. The end of the slide away from the limiting groove is connected to the upper surface of the slide, and the end of the slide rod away from the second movable rod is located in the slide groove.

[0015] The advantages and positive effects of the I-shaped sealing rubber ring for drainage inspection wells described in the present invention are:

[0016] 1. The present invention installs an I-shaped rubber ring on the outer wall of the drain pipe, and the inner diameter of the rubber ring is consistent with the outer diameter of the drain pipe. Since the rubber ring is a flexible material, it can play a good coordination role when the inspection well and the drainage pipe are unevenly settled. In addition, due to the expansion effect of the rubber ring, the connection between the drainage pipe and the inspection well can be made more airtight, ensuring that there is no water leakage between the drainage pipe and the inspection well.

[0017] 2. The inner side of the rubber ring of the present invention contacts the outer wall of the drain pipe, and the outer side contacts the inner wall of the mounting hole. The clamping force of the inner wall of the mounting hole and the outer wall of the drain pipe pushes the sealing strip to move toward the mounting groove, and pushes the first push rod and the second push rod to move into the mounting groove. The spring is compressed, and the distance between the first movable rod and the second movable rod is shortened. The slide bar slides in the limit groove and slides out of the limit groove along the slideway. At this time, the slide seat and the slide bar are separated. Under the action of the spring extension, the distance between the first push rod and the second push rod is increased, so that the first support plate and the second support plate push and squeeze the side walls of the mounting groove respectively, so that the surrounding of the ring body is better sealed to the drain pipe and the mounting hole, thereby improving the sealing effect of the rubber ring during sealing.

[0029] Example

[0030] like Figure 1 As shown, an I-shaped drainage inspection well 1 has a built-in rubber ring 4 at the wellhead, including an inspection well 1, a drainage pipe 2, and an inspection well 1 base 3. The bottom of the inspection well 1 is located on the inspection well 1 base 3. Drainage pipes 2 are provided on both side walls of the inspection well 1. An anti-corrosion layer (not shown in the figure) is provided on the outer wall of the drainage pipe 2. A mounting hole for the drainage pipe 2 is provided on the side wall of the inspection well 1. One end of the drainage pipe 2 is connected to the mounting hole through cement mortar. The cement mortar fills the gap between the mounting hole and the drainage pipe 2. The cement mortar can be selected as an expansion cement mortar. A rubber ring 4 is sleeved on the outer side of one end of the drainage pipe 2 located at the mounting hole. The rubber ring 4 is a flexible material. When the inspection well 1 and the drainage pipe 2 are unevenly settled, it can play a good coordination role. In addition, due to the expansion of the rubber ring 4, the connection between the drainage pipe 2 and the inspection well 1 can be made more airtight, ensuring that there is no water leakage between the drainage pipe 2 and the inspection well 1.

[0031] like Figure 2 and Figure 3 As shown, the rubber ring 4 is in an I-shape, and includes an extension edge 5 and a ring body 6. The extension edge 5 is located at the top and bottom of the ring body 6, and extends to the outside of the ring body 6. The inner diameter of the rubber ring 4 is consistent with the outer diameter of the drain pipe 2, and its thickness is 200mm greater than the thickness of the wall of the inspection well 1. The inner side of the rubber ring 4 contacts the outer wall of the drain pipe 2, and the outer side contacts the inner wall of the installation hole. The extension edges 5 on the upper and lower sides of the rubber ring 4 contact the inner and outer side walls of the inspection well 1, respectively.

[0032] like Figure 4 As shown, a mounting groove 18 is provided inside the ring body 6 , and a sealing assembly is provided inside the mounting groove 18 . The sealing assembly includes a first push rod 8 , a second push rod 9 , a first movable rod 13 , a second movable rod 14 , a spring 12 , a first support plate 10 , and a second support plate 11 .

[0033] like Figure 5 As shown, the installation grooves 18 are distributed along the circumference of the ring body 6 to form a ring. There are multiple sealing components, which are evenly spaced along the circumference of the installation grooves 18 inside the ring body 6.

[0034] One end of the first movable rod 13 is connected obliquely to one end of the first push rod 8, one end of the second movable rod 14 is connected obliquely to one end of the second push rod 9, the other ends of the first push rod 8 and the second push rod 9 respectively penetrate the side wall of the mounting groove 18 and are in sliding contact with the side wall of the mounting groove 18, a spring 12 is provided between the first movable rod 13 and the second movable rod 14, one end of the spring 12 is connected to the inner side wall of the first movable rod 13, and the other end thereof is connected to the inner side wall of the second movable rod 14, a fixing rod 17 is provided at the bottom of the mounting groove 18, the other ends of the first movable rod 13 and the second movable rod 14 are respectively connected to the fixing rod 17 for rotation, and the fixing rod 17 is distributed in the mounting groove 18 in an annular shape. The fixing rod 17 is fixedly connected to the bottom of the mounting groove 18, the rotational connection between the first movable rod 13, the second movable rod 14 and the fixing rod 17 belongs to the prior art, and the first movable rod 13 and the second movable rod 14 are close to each other without affecting the rotational connection.

[0035] The first push rod 8 penetrates the first support plate 10 , the second push rod 9 penetrates the second support plate 11 , and the side surfaces of the first support plate 10 and the second support plate 11 are in contact with the inner wall surface of the installation groove 18 respectively.

[0036] A slide seat 15 is provided on the inner side of the first movable rod 13, and a slide bar 16 is provided on the inner side of the second movable rod 14. The slide bar 16 slides in the slide seat 15, one end of the slide seat 15 is fixedly connected to the first movable rod 13, and one end of the slide bar 16 is rotatably connected to the second movable rod 14. The rotatable connection between the slide bar 16 and the second movable rod 14 facilitates the slide bar 16 to slide out of the slide seat 15.

[0037] like Figure 6 As shown, a limiting groove 21 is provided at one end of the slide 15 away from the first movable rod 13, and an arc-shaped slide 19 is provided at one end of the limiting groove 21. The end of the slide 19 away from the limiting groove 21 is connected to the upper surface of the slide 15, and the end of the slide 16 away from the second movable rod 14 is located in the slide. A limiting block 20 connected to the slide 16 is provided on the inner side of the slide. The height of the end of the slide 19 close to the limiting groove 21 is lower than the height of the end of the slide 19 away from the limiting groove 21. The limiting block 20 plays a role in limiting the slide 16, so that the slide 16 is located in the limiting groove 21. The arc-shaped slide 19 makes one end of the slide 19 higher than the other end. When the slide 16 slides along the slide 19, the slide 16 slides closer to the first movable rod 13 as the arc-shaped slide 19 is set, and the higher the height of the slide 16 is, the easier it is for the slide 16 to slide out of the limiting groove 21.

[0038] The first push rod 8 and the second push rod 9 are respectively attached with sealing strips 7 at one end, and the two sides of the sealing strips 7 are integrally formed on the two sides of the ring body 6. The sealing strip 7 is made of rubber and has a certain elasticity. The inner side of the rubber ring 4 contacts the outer wall of the drain pipe 2, and the outer side contacts the inner wall of the installation hole. The extended edge 5 contacts the side wall of the inspection well 1. When the expansion cement mortar is filled in the gap between the installation hole and the drain pipe 2, the clamping force of the inner wall of the installation hole and the outer wall of the drain pipe 2 pushes the sealing strips 7 on both sides of the ring body 6 to move toward the installation groove 18, thereby pushing the first push rod 8 and the second push rod 9 to move into the installation groove 18, the spring 12 is compressed, the distance between the first movable rod 13 and the second movable rod 14 is shortened, the sliding rod 16 slides in the limit groove 21, and slides out of the limit along the slide 19. The sliding seat 15 and the sliding rod 16 are separated at this time, and the distance between the first push rod 8 and the second push rod 9 is increased under the effect of the rebound extension of the spring 12, so that the first support plate 10 and the second support plate 11 push and squeeze the side walls of the installation groove 18 respectively, that is, the first push rod 8 and the second push rod 9 open the first movable rod 13 and the second movable rod 14 under the effect of the rebound of the spring 12, and the first support plate 10 and the second support plate 11 open the installation groove 18, so that the surrounding of the ring body 6 is better sealed to the drain pipe 2 and the installation hole, thereby improving the sealing effect of the rubber ring 4 during sealing.

[0039] Therefore, the present invention adopts the above-mentioned I-shaped sealing rubber ring for the drainage inspection well to solve the existing problem that uneven settlement of the inspection well and the drainage pipe will cause the interface to be torn or broken, resulting in water leakage between the drainage pipe and the inspection well, thereby causing pollution to the groundwater environment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
