AI Technical Summary
In the existing outdoor cable trench design, the cable is directly exposed to the trench, causing rainwater to seep into and soak the cable, damage the insulation layer, and shorten the cable life.
An outdoor cable trench structure is designed, including cable trench, pressure gland, drainage trench and drainage holes. The pressure-resistant gland is fixed to the cable trench by cuttings and sealing strips. The drain tank and drain holes are used to guide and drain rainwater to ensure that the cable is not immersed in water.
Effectively prevent rainwater from entering the cable trench, avoiding the cable immersion, extending the service life of the cable, and increasing the compressive resistance of the cable trench through the arched pressure-resistant gland.

[0021] Furthermore, sealing covers are slidably arranged inside the plurality of countersunk holes.
[0022] Through the above solution, the sealing cover is used to seal the countersunk hole after the second fixing bolt is installed.
[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0024] The outdoor cable trench structure can realize that if rainwater enters the cable trench, it can flow out through the drainage hole by setting a pressure-resistant cover, a drainage groove and a drainage hole. When in use, the cable trench is first placed in the pre-dug ground, and the pressure-resistant cover is inserted into the installation groove through the slot to fix the pressure-resistant cover. When rainwater seeps into the cable trench, the pressure-resistant cover guides the rainwater to the drainage groove, and then the rainwater is discharged through the drainage hole at the bottom of the drainage groove.
