Description

A leak-proof structure for power inspection wells Technical Field

[0001] This utility model relates to the field of power inspection well technology, specifically to a seepage-proof structure for power inspection wells. Background Technology

[0002] A power inspection well is an underground facility used in power systems. It is mainly used for laying, inspecting, maintaining, and troubleshooting power cables. It consists of a well body, a well cover, and cable equipment. The well body is usually made of reinforced concrete, which has a certain strength and stability and can withstand the pressure of the ground and the lateral pressure of the surrounding soil. The shape of the well body is generally circular or rectangular. The well cover is located on top of the inspection well and its main function is to cover the well opening to prevent people and objects from falling into the well. It also plays a certain role in waterproofing and dustproofing.

[0003] However, although existing electrical inspection wells have covers for waterproofing, they are not comprehensive. When it rains, rainwater may enter the well from the connection between the cover and the well opening, or from the cable access points on both sides of the well. Electrical equipment and cables are usually installed inside the inspection well. If a large amount of rainwater enters and accumulates, it may cause electrical equipment to become damp and short-circuit, leading to power outages and affecting the normal operation of the power system.

[0004] Therefore, a seepage-proof structure for power inspection wells is needed. Summary of the Invention

[0005] The purpose of this utility model is to provide a seepage-proof structure for power inspection wells, in order to solve the problem mentioned in the background art that although existing power inspection wells have well covers for waterproofing, they are not comprehensive. When it rains, rainwater may enter the well from the connection between the well cover and the well opening, or from the cable access points on both sides of the well body. Power equipment and cables are usually arranged inside the inspection well. If a large amount of rainwater enters and accumulates, it may cause electrical equipment to become damp and short-circuited, leading to power outages and affecting the normal operation of the power system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seepage-proof structure for an electrical inspection well, comprising a well body, a waterproof concrete connected to the top of the well body, a wellhead assembly connected to the top of the waterproof concrete, a top waterproof assembly installed on the top of the wellhead assembly, through grooves opened on both sides of the well body, connecting assemblies installed inside the two through grooves, and a sealing assembly threadedly connected inside the connecting assemblies.

[0007] Preferably, the outer wall of the well body is provided with a waterproof mortar layer, and the inside of the well body is coated with polyurethane waterproof coating. The waterproof mortar has high density and can effectively fill the tiny pores and cracks on the surface of the well body concrete, greatly improving the impermeability of the well body and reducing the possibility of rainwater, groundwater and other water seeping into the inspection well through the well wall. The waterproof coating can form a continuous and seamless waterproof membrane on the inner wall of the well body. This waterproof membrane has good flexibility and water resistance.

[0008] Preferably, the wellhead assembly includes a top plate, which is fixedly connected to the top of the waterproof concrete. The top of the waterproof concrete has a through slot, and a top opening is fixedly installed inside the slot. The top of the top opening has an installation groove.

[0009] Preferably, the top waterproof component includes a top cover and two drainage channels. The two drainage channels are symmetrically opened on both sides of the top opening. Both drainage channels are connected to the mounting groove. The top cover is installed inside the mounting groove, which allows rainwater accumulated near the well opening to be quickly drained away through the channels, preventing rainwater from accumulating in large quantities at the well opening or even flowing into the well, thus reducing the risk of rainwater soaking the equipment and cables inside the inspection well.

[0010] Preferably, the connecting assembly includes two mounting shells, each with a threaded groove at one end and a connecting plate fixedly mounted at the other end. The two mounting shells are respectively installed inside two through grooves, and cable protection tubes are installed inside both mounting shells. During installation, it is only necessary to align and tighten the threaded parts. The operation is relatively simple and does not require complicated tools or professional skills.

[0011] Preferably, the sealing assembly includes two threaded blocks, which are respectively installed inside two threaded grooves. A sealing ring is fixedly installed inside the threaded blocks. The two threaded blocks are sleeved on the outside of the two cable protection pipes. The threaded connection can achieve a relatively tight fit. By tightening the threads, the connection parts on both sides of the inspection well can be squeezed against each other, effectively filling the gap, thereby forming a good seal and preventing rainwater, groundwater and other liquids from seeping into the well.

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

[0013] The wellhead assembly and the top waterproof assembly prevent rainwater from entering the interior of the well from the top opening;

[0014] By connecting the components and sealing components and tightening the threads, the connecting parts on both sides of the inspection well can be squeezed against each other, effectively filling the gaps and forming a good seal. This prevents rainwater, groundwater and other liquids from seeping into the well, and also prevents gas or harmful substances from leaking into the outside.

[0015] Waterproof mortar on the outside of the well reduces rainwater seepage, while polyurethane waterproof coating inside the well forms a waterproof membrane to block external water and prevent moisture from entering.

[0016] Through a combination of waterproofing and sealing techniques, rainwater can be effectively prevented from entering the well, preventing equipment from short circuits, leakage, and other malfunctions caused by moisture or water ingress, extending the service life of the equipment, and ensuring the stable operation of the power system.

[0022] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figures 1-4. This utility model provides a seepage-proof structure for an electrical inspection well, including a well body 1, a waterproof concrete 2 connected to the top of the well body 1, a wellhead assembly connected to the top of the waterproof concrete 2, a top waterproof assembly installed on the top of the wellhead assembly, through grooves on both sides of the well body 1, connecting assemblies installed inside the two through grooves, and sealing assemblies threaded inside the connecting assemblies.

[0024] Furthermore, the outer wall of the well body 1 is provided with a waterproof mortar layer 9, and the interior of the well body 1 is coated with polyurethane waterproof coating 8. The waterproof mortar layer 9 can form a solid protective layer on the outer wall of the well body 1, which can not only prevent external moisture from seeping into the well body 1, but also resist the erosion of the well body 1 structure by harmful substances in the soil. The polyurethane waterproof coating 8 can form a continuous and seamless waterproof membrane on the inner wall of the well body 1. This waterproof membrane has good flexibility and water resistance.

[0025] Furthermore, the wellhead assembly includes a top plate 3, which is fixedly connected to the top of the waterproof concrete 2. The top of the waterproof concrete 2 has a through slot, and a top opening 4 is fixedly installed inside the slot. An installation groove 5 is opened on the top of the top opening 4. The top waterproof assembly includes a top cover 7 and two drainage channels 6. The two drainage channels 6 are symmetrically opened on both sides of the top opening 4. Both drainage channels 6 are connected to the installation groove 5. The top cover 7 is installed inside the installation groove 5. The bottom of the top cover 7 fits the inner wall of the installation groove 5. When it rains, a small amount of rainwater may enter between the top cover 7 and the installation groove 5. When the water enters the interior of the installation groove 5, it will flow out through the two drainage channels 6 connected to the installation groove 5.

[0026] Furthermore, the connecting assembly includes two mounting shells 10, each with a threaded groove 12 at one end and a connecting plate 11 fixedly mounted at the other end. The two mounting shells 10 are respectively installed inside the two through grooves, and cable protection tubes 15 are installed inside the two mounting shells 10. The sealing assembly includes two threaded blocks 13, each installed inside the two threaded grooves 12. A sealing ring 14 is fixedly mounted inside the threaded blocks 13. The two threaded blocks 13 are sleeved on the outside of the two cable protection tubes 15, and the outer wall of the cable protection tubes 15 matches the inner wall of the mounting shells 10 and the two threaded blocks 13.

[0027] In this embodiment, during construction of the well body 1, bricks and cement are used to build the structure, and through-grooves are pre-reserved. After the construction is completed, cement mortar is applied to the outside. After the cement mortar dries, a waterproof mortar layer 9 is applied to the outer wall of the well body 1. The waterproof mortar layer 9 on the outside of the well body 1 waterproofs the outside of the well body 1. A polyurethane waterproof coating 8 is applied to the inner wall of the well body 1. The polyurethane waterproof coating 8 inside the well body 1 prevents moisture from entering the interior of the well body 1. When waterproofing and sealing both sides of the well body 1, two mounting shells 10 are first placed inside the two through-grooves, so that the two connecting plates 11 are tightly attached to the inner wall. Then, two cable protection pipes 15 are inserted into the middle of the two mounting shells 10. Finally, the threaded block 13 is fitted onto the cable protection pipes. On the protective pipe 15, two threaded blocks 13 are threaded into the threaded grooves 12 of the two mounting shells 10. The threaded blocks 13 and the connecting plate 11 clamp the inner and outer walls of the well body 1. When the threaded blocks 13 are tightened to a certain extent, the sealing ring 14 is released from the outer wall of the well body 1. When tightening is continued, the sealing ring 14 squeezes the outer wall of the well body 1 to seal the through groove and prevent leakage. When it rains, a small amount of rainwater may enter between the top cover 7 and the mounting groove 5. When the water enters the interior of the mounting groove 5, it will flow out through the two drainage grooves 6 connected to the mounting groove 5. When the staff needs to enter the interior of the well body 1 to work, the top cover 7 is removed and a ladder is set at the top opening 4 to enter the interior of the well body 1 to work.
