Abstract

The invention relates to PVC tube drainage equipment, in particular to a PVC tube drainage device. The PVC tube drainage device comprises a tubular drainage nozzle and a hanging rod. A position clamping ring is arranged at the upper end of the tube body of the drainage nozzle, the tube body of the drainage nozzle is further provided with a hanging hole located below the position clamping ring, a first hook capable of being hung on the tube body of a PVC tube is arranged at the top end of the hanging rod, a second hook matched with the hanging hole is arranged at the bottom end of the hanging rod, the first hook and the second hook are integrally connected with the hanging rod, the opening diameter of the upper end of the tube body of the drainage nozzle is 20 mm, the opening diameter of the lower body of the tube body is 15 mm, and the tube body is 30 millimeter high. The PVC tube drainage device is novel and practical in structure, can effectively drain rainwater flowing into the PVC tube and solves the problem that frost cracking of optical cables occurs in winter due to the fact that the rainwater flowing into the PVC tube in an optical cable inspection well cannot be drained off.

Description

technical field

[0001] The invention relates to drainage equipment for PVC pipes, in particular to a drainage device for PVC pipes. Background technique

[0002] With the continuous deepening of the transformation of the power system, informatization, automation, digitization, and intelligence are widely used in the field of communication equipment transmission, so it is very important to ensure the safe operation of optical cables. At present, the optical cables used in the power system include ground wire composite overhead optical cable (OPGW) and all-dielectric self-supporting optical cable (ADSS). These optical cables are introduced from the substation and power supply tower to the communication room. In the inspection shaft, it is finally led out from the cable inspection shaft into the communication room. The optical cable drawn from the top of the tower should be set in a PVC pipe. The PVC pipe can protect the optical cable. The mouth of the optical cable entering th...

Embodiment Construction

[0012] The PVC pipe drainage device includes a tubular drainage nozzle 1 and a hanging rod 2. The upper end of the pipe body of the drainage nozzle 1 is provided with a clamping ring 3, and the body of the drain pipe 1 is also provided with a hanging hole located below the clamping ring. The top of the bar 2 is provided with a first hook 4 that can be hung on the body of the PVC pipe, and the bottom end of the bar is provided with a second hook 5 that matches the hanging hole.

[0013] In the above-mentioned PVC pipe drainage device, the first hook 4 at the top of the hanging rod and the second hook 5 at the bottom are integrally connected with the hanging rod 2 .

[0014] In the above-mentioned PVC pipe drainage device, the opening diameter of the upper end of the pipe body of the drain nozzle 1 is larger than the opening diameter of the lower end.

[0015] In the above-mentioned PVC pipe drainage device, the opening diameter of the upper end of the pipe body of the drain noz...
