Description

Technical Field

[0001] This utility model relates to a cable conduit burial structure, and particularly to a cable conduit burial structure applied in the field of cable conduit laying. Background Technology

[0002] Cable conduit is a type of pipe used to protect cables, distinguish cable functions, and facilitate wiring and maintenance. It is generally made of corrosion-resistant and leakage-proof rigid PVC tubing. In addition, depending on the application scenario, iron, stainless steel, carbon steel and other materials are also used.

[0003] The introduction of protective pipes and air into conduits significantly increases thermal resistance, reducing the allowable current carrying capacity of cables by approximately 10% compared to direct burial. Furthermore, the heat generated by the cable during burial causes the surrounding soil to dry out, leading to a substantial increase in the soil's thermal resistivity, exceeding the cable's allowable operating temperature. To avoid this, the cable cross-section selected during design is typically larger. Additionally, the heated soil causes continuous moisture migration, further increasing thermal resistance. Once the soil becomes thermally unstable, it can lead to cable overheating and breakdown, severely jeopardizing the reliability of the power supply system. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when cables are laid underground in conduits, the soil around the conduits becomes dry due to the heat generated by the cables, which leads to an increase in the soil's thermal resistance coefficient and may cause soil thermal instability. This can cause the cables to overheat and break down, seriously endangering the power supply reliability of the power system.

[0005] To address the aforementioned problems, this utility model provides a cable conduit burial structure, comprising two sets of positioning tubes respectively fitted onto both ends of the cable conduit. Each positioning tube includes two mounting tubes symmetrically distributed and fixedly connected by bolts. A sealing ring is fixedly connected inside each mounting tube, and an insert tube is fixedly connected to the outer surface of each mounting tube. A collection hopper is fixedly connected to the end of the insert tube away from the mounting tube, and a filter screen is fixedly connected inside the collection hopper. Two irrigation components are provided between the two sets of positioning tubes. Each irrigation component includes two mounting plates respectively fixedly connected to two adjacent mounting tubes. A support tube is provided at one corresponding end of each mounting plate, and a pressure plate is fixedly fitted onto the outer surface of the support tube. Two limiting grooves are chiseled into the surface of each mounting plate, and limiting strips are provided in the limiting grooves and fixedly connected to the adjacent pressure plates. An adjusting tube is provided at one corresponding end of each of the two support tubes, and a water collection pipe is provided between the two adjusting tubes. Both ends of the water collection pipe are threaded through the adjacent adjusting tubes and extend into the adjacent mounting tubes respectively. Multiple mounting sleeves are fixedly fitted onto the outer surface of the water collection pipe, and a drain pipe is fixedly connected to the outside of the mounting sleeves. An electric valve is installed outside the drain pipe.

[0006] In the above-mentioned cable conduit burial structure, rainwater is collected by collecting buckets and inserting pipes during rainy days, and the rainwater is stored in the installation pipe and water collection pipe. When the soil around the cable conduit is relatively dry, the collected rainwater can be used to drip irrigate the soil around the cable conduit, thereby effectively increasing soil moisture, effectively avoiding soil thermal instability, and improving the power supply reliability of the power system.

[0007] As a further improvement to this application, both the mounting tube and the sealing ring are semi-circular, and the sealing ring is made of rubber.

[0008] As a further improvement of this application, the insertion tube is a telescopic flexible hose, the cross-section of the collection hopper is trapezoidal, and the collection hopper is located above the installation pipe. The collection hopper, insertion tube, installation pipe, water collection pipe, and drain pipe are connected.

[0009] As a further improvement of this application, both the limiting groove and the limiting strip are T-shaped, and the two irrigation components are symmetrically distributed.

[0010] As another improvement of this application, the drain pipe is located below the cable conduit, and the drain pipes on the two irrigation components are distributed in a figure-eight pattern.

[0011] As a further improvement to this application, a permeable membrane is fixedly fitted on the outer surface of the drain pipe, and a mud-proof sleeve is fixedly fitted on the outer surface of the permeable membrane. The mud-proof sleeve has a mesh structure.

[0012] In summary, in practical applications, during rainy days, rainwater falls into the collection hopper, passes through the insertion pipe into the installation pipe, and then enters the water collection pipe for storage. An external temperature and humidity sensor can monitor the moisture content and temperature of the soil near the cable conduit. When the temperature is too high or the humidity is too low, an electric valve can be activated to open, allowing water to drip out of the water collection pipe through the drain pipe, thus irrigating the soil near the cable conduit and increasing its moisture content. This effectively prevents soil thermal instability and improves the reliability of the power supply system. Attached Figure Description

Detailed Implementation

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1 , Figure 2 and Figure 3 The diagram illustrates a cable conduit burial structure, comprising two sets of positioning tubes 1 respectively fitted onto both ends of the cable conduit. Each positioning tube 1 includes two mounting tubes 101, symmetrically distributed and fixedly connected by bolts. The mounting tubes 101 can be used to install and fix the outer surfaces of the two cable conduits. A sealing ring 102 is fixedly connected inside each mounting tube 101. Both the mounting tube 101 and the sealing ring 102 are semi-circular. The sealing ring 102 is made of rubber and seals the interface between the two cable conduits. An insertion tube 103 is fixedly connected to the outer surface of each mounting tube 101. A collection hopper 104 is fixedly connected to the end of pipe 103 away from the installation pipe 101. A filter screen 105 is fixedly connected inside the collection hopper 104. The insertion pipe 103 is a telescopic flexible hose. The cross-section of the collection hopper 104 is trapezoidal, and the collection hopper 104 is located above the installation pipe 101. The collection hopper 104, insertion pipe 103, installation pipe 101, water collection pipe 8, and drainage pipe 10 are connected. The insertion pipe 103 can be stretched according to the pre-buried depth of the cable conduit. When using soil burial, the collection hopper 104 is located above the soil, which facilitates rainwater entering the collection hopper 104. The filter screen 105 can filter large particulate impurities in the rainwater.

[0024] Figure 1 , Figure 4 and Figure 5The diagram shows two irrigation components symmetrically distributed between two sets of positioning pipes 1. Each irrigation component includes two mounting plates 2 fixedly connected to two adjacent mounting pipes 101. Support pipes 3 are provided at corresponding ends of the two mounting plates 2. Pressure plates 4 are fixedly fitted onto the outer surface of the support pipes 3. Two limiting grooves 5 are chiseled into the surface of the mounting plates 2, and limiting strips 6 are provided within the limiting grooves 5. Both the limiting grooves 5 and the limiting strips 6 are T-shaped. The limiting strips 6 are fixedly connected to the adjacent pressure plates 4. Adjusting pipes 7 are provided at corresponding ends of the two support pipes 3. A water collection pipe 8 is provided between the two adjusting pipes 7. Both ends of the water collection pipe 8 are threaded through the adjacent adjusting pipes 7 and extend into the adjacent mounting pipes 101. Multiple mounting sleeves 9 are fixedly fitted onto the outer surface of the water collection pipe 8. A drain pipe 10 is fixedly connected to the outside of the mounting sleeves 9. An electric valve 11 is installed outside the drain pipe 10. Those skilled in the art can select according to actual needs. A suitable model of electric valve 11, such as D341X-10C, is used. The drain pipe 10 is located below the cable conduit. The drain pipes 10 on the two irrigation components are arranged in a figure-eight pattern. When installing the water collection pipe 8, a set of positioning pipes 1 can be installed on the outer surface of the cable conduit first. Then, the limiting strip 6 is pushed into the limiting groove 5 so that the pressure plate 4 and the mounting plate 2 are in contact. Then, one end of the water collection pipe 8 is inserted into the regulating pipe 7. By rotating the regulating pipe 7, the water collection pipe 8 is moved toward the mounting pipe 101 until the water collection pipe 8 is inserted into the mounting pipe 101. Then, the pressure plate 4 and the mounting plate 2 at the other end of the water collection pipe 8 are installed and inserted into the water collection pipe 8. Then, the regulating pipe 7 is rotated so that the mounting pipe 101 is moved toward the water collection pipe 8 until the other end of the water collection pipe 8 enters the mounting pipe 101. Then, the two mounting pipes 101 in the other set of positioning pipes 1 are fixed to complete the installation of this application, thereby facilitating the disassembly of this application.

[0025] When laying cable conduits, the positioning pipe 1 is fitted onto the outer surface of the cable conduit, and then the water collection pipe 8 is installed. On rainy days, rainwater falls into the collection hopper 104, and impurities in the rainwater are filtered through the filter screen 105. The rainwater then passes through the insertion pipe 103 and falls into the installation pipe 101, and then enters the water collection pipe 8 for storage. An external temperature and humidity sensor can monitor the moisture content and temperature of the soil near the cable conduit. When the temperature is too high or the humidity is too low, the electric valve 11 can be activated to open, and the water in the water collection pipe 8 can drip out through the drain pipe 10, thereby irrigating the soil near the cable conduit to increase the soil moisture and effectively prevent soil thermal instability, thus improving the power supply reliability of the power system.

[0026] Second implementation method:

[0027] This embodiment adds a permeable membrane 12 and a mud-proof sleeve 13 to the first embodiment, while the rest remains the same as the first embodiment.

[0028] Figure 6 As shown: a permeable membrane 12 is fixedly sleeved on the outer surface of the drain pipe 10, and a mud-proof sleeve 13 is fixedly sleeved on the outer surface of the permeable membrane 12. The mud-proof sleeve 13 has a mesh structure.

[0029] When drip irrigation is performed on the soil through the drainage pipe 10, the water first enters the permeable membrane 12 and seeps out through the permeable membrane 12 to irrigate the soil. The mud-proof sleeve 13 can effectively prevent large particles of mud and sand from entering the drainage pipe 10, while the permeable membrane 12 can effectively prevent small particles of mud and sand from entering the drainage pipe 10. This effectively prevents the drainage pipe 10 from becoming blocked during irrigation and effectively extends the service life of the drainage pipe 10.

[0030] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
