Description

Technical Field

[0001] The present application relates to the technical field of anti-seepage construction, and in particular to a device for preventing water leakage from a pipe opening of a power pipe well. Background Art

[0002] The power pipe well is a device set up to facilitate the inspection of underground power lines. Since there are a large number of pipelines in the power pipe well, if the pipelines are damaged due to long service life, water entering the power pipe well may cause damage to the lines or even accidents.

[0003] During periods of heavy rain, the surface of the manhole cover of the power pipe well will be covered by rainwater for a long time, and some rainwater will flow into the power pipe well from the gap between the power pipe well and the manhole cover. Therefore, an improvement is now made to a device for preventing water leakage from the pipe opening of the power pipe well. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a device to prevent water leakage from the pipe opening of the power pipe well, which overcomes the shortcomings of the existing technology and aims to solve the problem that during periods of heavy rain, the surface of the manhole cover of the power pipe well will be covered by rainwater for a long time, and some rainwater will flow into the power pipe well through the gap between the power pipe well and the manhole cover.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a device for preventing water leakage from the mouth of an electric pipe well, comprising an electric pipe well, an outer wall of one side of the electric pipe well being inlaid with an embedded pipe, an electric cable being arranged inside the embedded pipe, a manhole cover being placed on the top of the electric pipe well, a limiting block being arranged inside the electric pipe well below the manhole cover, limiting grooves being symmetrically provided on both sides of the inner wall of the electric pipe well, an adjusting block being slidingly inserted into the inner part of the limiting groove, an end of the adjusting block away from the limiting block being located inside the limiting groove, a connecting rod being fixedly connected to the top of the limiting block, the upper end of the connecting rod slidingly passing through the manhole cover and extending to the outside, the outer surface of the connecting rod being located above the manhole cover, and a waterproof cover and an extrusion block being sequentially sleeved from bottom to top, an external thread 1 being provided on the outer surface of the connecting rod near the middle position, and the connecting rod being threadedly connected to a fixing ring through the external thread 1.

[0006] By adopting the above technical solution, by opening a limit groove, the adjustment block and the limit block are fixed inside the power pipe well, so that the well cover, waterproof cover and extrusion block can be sequentially sleeved on the connecting rod, and the waterproof cover can be clamped on the top of the power pipe well by twisting the fixing ring, thereby sealing the connection between the power pipe well and the well cover, preventing some rainwater from flowing into the interior of the power pipe well through the gap between the power pipe well and the well cover, thereby ensuring that the cable is in a safe environment and avoiding damage to the cable.

[0007] As a preferred technical solution of the present application, two adjustment grooves are symmetrically provided inside the limit block, a spring is fixedly connected to the inner wall of the adjustment groove, and the other end of the spring is fixedly connected to the adjustment block.

[0008] By adopting the above technical solution, the position of the adjustment block is adjusted by the spring, thereby adjusting the overall length of the limit block and the two adjustment blocks, so that the adjustment block and the limit block can be fixed inside the limit groove.

[0009] As a preferred technical solution of the present application, two plug-in holes are symmetrically opened on both sides of the lower surface of the limit block near the port position, the limit block is threadedly connected with a fixing bolt through the plug-in hole, and the lower surfaces of the two adjustment blocks are both provided with fixing holes, and the fixing holes are adapted to the plug-in holes.

[0010] By adopting the above technical solution, most of the adjustment block can be confined in the adjustment slot, thereby reducing the space occupied during the idle process.

The rubber pad is located between the waterproof cover and the power pipe well and there is no gap between the two.

[0012] By adopting the above technical solution and arranging the rubber pad, there is no gap between the waterproof cover and the power pipe well, thereby preventing rainwater from seeping into the power pipe well.

[0013] As a preferred technical solution of the present application, a sealing groove is provided on the top of the waterproof cover, and a sealing strip adapted to the sealing groove is fixedly connected to the bottom of the extrusion block. The bottom of the extrusion block abuts against the top of the waterproof cover, and the bottom of the fixing ring abuts against the top of the extrusion block.

[0014] By adopting the above technical solution, the fixing ring will squeeze the extrusion block during the process of twisting the fixing ring, so that the sealing strip is embedded in the inside of the sealing groove, thereby sealing the connection between the extrusion block and the waterproof cover, making the extrusion block and the waterproof cover connected more tightly, and preventing rainwater from seeping into the inside of the power pipe well from the connection between the two.

[0015] As a preferred technical solution of the present application, a sealing material is provided inside the embedded pipe, and the inner wall of the sealing material is in contact with the outer wall of the cable.

[0016] By adopting the above technical solution, the sealing performance of the device is further improved.
