Problems solved by technology

At present, the position where the cable is led out of the elbow is usually not well sealed, and groundwater will seep into the elbow. After the water level rises to a certain position, it will also enter the horizontal pipe, causing corrosion to the cable and shortening the service life of the cable. big security risk

Abstract

The invention relates to a drainage type power pipe, which comprises a pipe body in which a cable is threaded. The pipe body includes a horizontal pipe and an elbow connected to the horizontal pipe. The end of the elbow away from the horizontal pipe is located in the cable well. There are several drainage holes on the outer arc surface, the height of the drainage holes is less than the height of the lowest surface of the inner wall of the horizontal pipe, and the height of the end of the drainage holes connected to the inside of the elbow is greater than the height of the end connected to the outside of the elbow. By setting drainage holes on the outer arc surface of the elbow, and the location of the drainage holes is lower than the horizontal pipe, it can be quickly discharged when water accumulates in the elbow, effectively preventing the accumulated water from entering the horizontal pipe and affecting the service life of the cable. Set the drain hole so that the inner end is higher than the outer end, so as to prevent the water falling from above, such as rainwater, from entering the elbow through the drain hole.

Description

technical field [0001] The invention relates to the technical field of power pipes, in particular to a drainage type power pipe. Background technique [0002] When the low-voltage cable is routed underground, in order to prevent the cable from being squeezed and damaged, a hard power tube is often used to protect the cable outside the cable. For example, when the cables are arranged between the cable box and the cable well in the power plant, the electric pipe is used to protect the cable. The electric pipe usually includes a horizontal pipe and an elbow. The elbow is fixed at the end of the horizontal pipe in the cable well. After setting the horizontal pipe and elbow, it is led out, and then connected with the equipment in the cable shaft. At present, the position where the cable is led out of the elbow is usually not well sealed, and groundwater will seep into the elbow. After the water level rises to a certain position, it will also enter the horizontal pipe, causing co...
