Description

Technical Field

[0001] The utility model relates to the technical field of building water and electricity construction, in particular to a building construction pre-buried pipe sealing device. Background Art

[0002] Hydropower is a clean energy that is renewable, pollution-free, and has low operating costs. It is convenient for power peak regulation and is conducive to improving resource utilization and the comprehensive benefits of the economy and society. Under the increasingly tight situation of traditional energy on the earth, countries around the world generally give priority to the development of hydropower and vigorously utilize water resources. China ranks first in the world in terms of both proven water resources reserves and potentially developable water resources. During the construction of hydropower buildings, the pipe openings of the embedded pipes need to be sealed. The original construction of hydropower embedded pipes in buildings often directly welds steel plates for sealing. Although it can ensure a certain degree of sealing, it is not durable enough. After long-term use, the impact and immersion of water flow can easily cause the steel plates to deform and cause leakage.

[0003] According to the patent application number 202020709609.7, the patent name is a patent for a pipe opening sealing device for pre-buried pipes for water and electricity in buildings. The patent includes a pre-buried pipe opening and a plug cap, and also includes a No. 1 screw and a nut. A connecting ring is welded and fixed to the periphery of the outer side surface of the plug cap, and a preset steel plate is welded and fixed to the outer side surface of the pre-buried pipe opening. After the No. 1 screw passes through the connecting ring and the preset steel plate, a nut is screwed and installed at its end by threading; a self-locking component is also installed on the plug cap; when in use, the utility model of the pipe opening sealing device for pre-buried pipes for water and electricity in buildings first uses the No. 1 screw to fix the plug cap, and then the self-locking component is activated by the operating component to improve the stability of the plug cap installation. At the same time, for the internal self-locking component, under the influence of water flow impact, the connecting rod will flip, ensuring that the rubber pad is more tightly attached to the inner wall of the pre-buried pipe opening, producing a self-locking effect, avoiding deformation or loosening of the plug cap, and having strong durability.

[0004] Although the above-mentioned patent has strong durability for sealing the construction openings of the water and electricity pre-buried pipes, the sealing mechanism is provided with multiple sets of nuts and screws, and the screws need to be screwed together with the corresponding nuts one by one to achieve installation. Therefore, the sealing efficiency of the construction openings of the water and electricity pre-buried pipes is low. Therefore, in order to solve the above problems, a sealing device for pre-buried pipes in construction is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pre-buried pipe sealing device for construction comprises a pre-buried pipe, a fixed sleeve welded to the outer right end of the pre-buried pipe, the right end of the pre-buried pipe contacts a sealing block, a connecting block in contact with the fixed sleeve is slidably connected to the left edge of the sealing block, a first spring is fixedly connected to the inner side of the connecting block, the other end of the first spring is fixedly connected to a clamping block passing through the connecting block, the inner center of the sealing block contacts a central block, a third spring is fixedly connected to the outer side of the central block, and the other end of the third spring is fixedly connected to the sealing block, the outer left end of the central block contacts a connecting rod, the outer right end of the connecting rod contacts a pressure ring in contact with the sealing block and the pre-buried pipe, and the right end of the pressure ring contacts a sealing ring.

[0008] As a further improvement of the present invention, the clamping block is slidably connected to the connecting block, the clamping block is clamped and connected to the fixing sleeve, and one end of the outer side of the clamping block is inclined.

[0009] As a further improvement of the present invention, one end of the outer side of the connecting block is rotatably connected to a pull rod via a rotating shaft, and the other end of the pull rod is rotatably connected to a slider in contact with the blocking block via a rotating shaft. One end of the outer side of the slider is fixedly connected to a clamping rod in contact with the blocking block and the center block, and a second spring is provided at one end of the outer side of the clamping rod, and the second spring is fixedly connected to the slider and the blocking block.

[0010] As a further improvement of the present invention, the sealing ring is made of rubber, and the sealing ring is in contact with the blocking block and the embedded pipe.

[0011] As a further improvement of the present invention, the outer side of the fixing sleeve is rotatably connected to a first threaded shaft that passes through the fixing sleeve, and the outer side of the first threaded shaft is spirally connected to a push block that is slidably connected to the fixing sleeve, and the push block is opposite to the clamping block.

[0012] As a further improvement of the present invention, a second threaded shaft is rotatably connected to the center of the inner side of the central block, and a positioning rod is spirally connected to the left end of the outer side of the second threaded shaft and is slidably connected to the central block, and the positioning rod is engaged with the connecting rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A device for sealing pre-buried pipes for construction, which is provided with a sealing block, a connecting block, a fixing sleeve, a clamping block, a pull rod, a clamping rod, a center block, a connecting rod, a pressure ring and a sealing ring. When sealing the construction pipe opening of the water and electricity pre-buried pipe during construction, the fixing sleeve is first welded to the right end of the outer side of the pre-buried pipe, and then the sealing block is manually pressed to insert the connecting block into the fixing sleeve. The clamping block is further compressed to form a first spring with smaller elastic force and then clamped together with the fixing sleeve. At this time, the sealing block can be sealed at the right end of the pre-buried pipe. After completing the above operations, as the sealing block is continued to be pushed, the connecting block will pull the slider through the pull rod during the sliding process with the sealing block. The slider will stretch the second spring in the process of driving the clamping rod to move. When the clamping rod is disengaged from the center block, the elastic force of the third spring on the center block will push the pressure ring through the connecting rod to extrude the rubber sealing ring, thereby ensuring the sealing between the sealing block and the embedded pipe after installation. By directly pressing the sealing block into the embedded pipe, the sealing block is further connected to the fixed sleeve on the outside of the embedded pipe through the clamping block in the connecting block. At the same time, the pressure ring extrude the rubber sealing ring to ensure the sealing between the sealing mechanism and the embedded pipe, thereby realizing rapid sealing of the construction pipe opening of the hydropower embedded pipe, and greatly improving the sealing efficiency.

[0015] 2. A sealing device for pre-buried pipes in construction, which is provided with a first threaded shaft, a push block, a second threaded shaft, a positioning rod, a center block and a third spring. When the sealing ring is aged after long-term use and the sealing between the device and the pre-buried pipe becomes poor, the first threaded shaft is first rotated to be spirally connected with the push block, and the blocking block is further pushed into the connecting block. Then, the center block is pressed into the pre-buried pipe to compress the third spring, and the pressure ring is further controlled by the connecting rod to no longer press the sealing ring. Then, the device is taken out of the pre-buried pipe, and finally the second threaded shaft is rotated to be spirally connected with the positioning rod, so that the positioning rod is no longer stuck with the connecting rod. After pushing the connecting rod and the pressure ring to slide and no longer in contact with the center block, it is convenient to remove the sealing ring for replacement after removing the pressure ring from the outside of the sealing block through the connecting rod. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 2

[0025] like Figure 2-3 As shown, in order to solve the problem of inconvenience in controlling the connection block 3 to be inserted into the fixed sleeve 15, the clamping block 5 is slidably connected to the connection block 3, and the clamping block 5 is engaged with the fixed sleeve 15. One end of the outer side of the clamping block 5 is tilted. By tilting the end of the clamping block 5 on the outer side of the connection block 3 close to the fixed sleeve 15, it is convenient to control the connection block 3 to be inserted into the fixed sleeve 15.

[0026] Example 3

[0027] like Figure 2-3 As shown, in order to solve the problem that it is inconvenient to control the pressure ring 13 to squeeze the sealing ring 14 after the blocking block 2 is connected to the right end of the embedded pipe 1, one end of the outer side of the connecting block 3 is rotatably connected to a pull rod 6 through a rotating shaft, and the other end of the pull rod 6 is rotatably connected to a slider 7 in contact with the blocking block 2 through a rotating shaft, and one end of the outer side of the slider 7 is fixedly connected to a clamping rod 8 in contact with the blocking block 2 and the center block 10, and one end of the outer side of the clamping rod 8 is provided with a second spring 9, and the second spring 9 is fixedly connected to the slider 7 and the blocking block 2. After being connected to the right end of the embedded pipe 1, as the blocking block 2 continues to be pushed in the direction of the embedded pipe 1, the slider 7 is pulled by the pull rod 6 during the further sliding of the connecting block 3 and the blocking block 2, so that the second spring 9 with larger elastic force is stretched during the process of the slider 7 driving the clamping rod 8 to move. When the blocking block 2 can no longer be pushed and the clamping rod 8 and the center block 10 just disengage, the elastic force of the third spring 11 on the center block 10 facilitates the control of the center block 10 to push the pressure ring 13 through the connecting rod 12 to extrude the rubber sealing ring 14.

By rotating the second threaded shaft 18 and spirally connecting the positioning rod 19, the positioning rod 19 is no longer stuck with the connecting rod 12. When the connecting rod 12 and the pressure ring 13 are pushed to slide and no longer contact the center block 10, it is convenient to release the connection between the connecting rod 12 and the center block 10.

[0034] When the sealing block 2 is unable to be pushed further, and the clamping rod 8 is just disengaged from the center block 10, the center block 10 will push the pressure ring 13 through the connecting rod 12 to squeeze the rubber sealing ring 14. When the sealing ring 14 is no longer in contact with the center block 10 after pushing the connecting rod 12 and the pressure ring 13 to slide, it is convenient to remove the sealing ring 14 from the outside of the sealing block 2 through the connecting rod 12 and replace it.
