Problems solved by technology

[0004] At present, with the development of agricultural mechanization, it is necessary to lay a large number of power pipelines in farmland, which generally use pipes with a diameter of 110mm to 250mm. In the case of branch wiring, the insulation cannot be effectively dealt with when connecting underground, and only underground wiring wells or ground branch junction boxes can be built. to a certain degree of influence

Embodiment 1

[0046] Such as figure 1 As shown, the present embodiment has an inlet section 1 and an outlet section 4 . The lead-in section 1 is used as the entry end of the buried pipeline, and is connected to the wiring pipe of the previous section. The lead-out section 4 is used as the outlet end of the buried pipeline, and is connected to the wiring pipe at the back. In this embodiment, a trapezoidal connecting portion 2 is provided between the connecting portion 2 communicating with the leading-in section 1 and the leading-out section 4 . The connection part 2 has three openings in total. In addition to connecting the lead-in section 1 and the lead-out section 4 as shown in the figure, it is also connected with a branch section 3, and the branch section 3 serves as a protection tube for the branch line. Since the connecting portion 2 is trapezoidal, the branch section 3 and the lead-out section 4 can be arranged in parallel, which is suitable for wiring where the direction of the bra...

Embodiment 2

[0048] Such as figure 2 As shown, the present embodiment has an inlet section 1 and an outlet section 4 . The lead-in section 1 is used as the entry end of the buried pipeline, and is connected to the wiring pipe of the previous section. The lead-out section 4 is used as the outlet end of the buried pipeline, and is connected to the wiring pipe at the back. In this embodiment, a triangular connecting portion 2 is provided between the connecting portion 2 communicating with the leading-in section 1 and the leading-out section 4 . The connection part 2 has three openings in total. In addition to connecting the lead-in section 1 and the lead-out section 4 as shown in the figure, it is also connected with a branch section 3, and the branch section 3 serves as a protection tube for the branch line. Since the connecting part 2 is triangular, the branch section 3, the lead-out section 4 and the lead-in section 1 can be arranged at different angles, which is suitable for wiring sit...

Embodiment 3

[0050] Such as image 3 As shown, the present embodiment has an inlet section 1 and an outlet section 4 . The lead-in section 1 is used as the entry end of the buried pipeline, and is connected to the wiring pipe of the previous section. The lead-out section 4 is used as the outlet end of the buried pipeline, and is connected to the wiring pipe at the back. In this embodiment, a wedge-shaped connecting portion 2 is provided between the connecting portion 2 communicating with the leading-in section 1 and the leading-out section 4 . The wedge-shaped connection part 2 has only two openings, and since the lead-in section 1 and the lead-out section 4 form a straight pipe, the wedge-shaped connection part 2 is inserted into the straight pipe and connected with a branch section 3 as a protection pipe of a branch circuit. This shape of underground branch conduit for buried wires is suitable for the case where the wiring with a very different angle from the aforementioned direction i...

Abstract

The invention provides an underground branch wiring pipe of a buried wire. The underground branch wiring pipe comprises a leading-in section, a leading-out section, a connecting part and at least onebranch section, and is characterized in that the connecting part is communicated between the leading-in section and the leading-out section, and the branch section is communicated with the connectingpart. The wiring pipe solves the technical problems in underground multi-branch wiring and effective insulation treatment of the buried wire, can greatly improve the construction progress, effectivelyreduces the cost and labor consumption, and reduces the damage to electric power facilities.

Description

technical field [0001] The invention relates to the technical field of power line paving consumables, in particular to an underground branch connection pipe for buried wires. Background technique [0002] The electric power threading pipe is mainly suitable for the threading protection of electric power engineering cables, the threading protection of telecommunication cables, and the threading protection of traffic communication cables, involving petroleum, chemical industry, urban construction and other fields. [0003] At present, the common pipes on the market mainly include steel pipes and plastic pipes. Steel pipes are mainly hot-dip galvanized steel pipes. Although ordinary steel pipes are strong, they are prone to rust and pollution, and their service life will be relatively short. Plastic pipes are made of MPP, PE, PVC and other materials. Although they have good corrosion resistance and strong finish, they are easily deformed by the influence of temperature, and ar...
