Rainwater head cover plate of substation

Abstract

The invention relates to fixed facility of a substation, in particular to a rainwater head cover plate of a substation, which comprises a cover plate base body, wherein the cover plate base body is provided with a grating groove running through up and down; edges of two sides of the back of the cover plate base board are provided with two insertion strips with L-shaped sections, vertical edges of the insertion strips are embedded into the cover plate base board, and horizontal edges of the insertion strips are positioned below the bottom face of the cover plate base body to enable gaps among the horizontal edge of the insertion strips and the bottom plane of the cover plate base body to form a pair of slots positioned at two sides; and a filter screen layer is horizontally inserted into the slots in a plug way, and can be freely inserted or drawn out of the slots. The invention has the advantages that: 1, the filter screen can prevent impurities with larger volume from entering a rainwater head so as to avoid the blockage of the rainwater head; 2, the drawable filter screen is convenient for cleaning the impurities and is more convenient; and 3, holes of the filter screen are smaller, which can prevent small animals from entering the rainwater head and a cable duct and ensures the safety operation of equipment.

Description

technical field [0001] The invention relates to a fixed facility of a substation, in particular to a substation rainwater drainage ditch cover plate. Background technique [0002] In the high-voltage site of the substation, each relatively independent equipment area must be equipped with a drainage ditch and a sewer cover to allow the rainwater to drain out of the station through the drain, and the drainage cover is usually a conventional concrete prefabricated grid structure. There are the following disadvantages: 1. The sundries enter the drainage ditch through the sewer cover, which will easily cause blockage of the sewer channel, affect the drainage of the substation, and may damage the drainage pump in serious cases; 2. After the sundries enter the drainage ditch, due to the large site, cleaning needs A lot of manpower and material resources are wasted; 3. The drainage ditch is connected with the cable ditch. Due to the large drain hole of the drainage cover plate, smal...

[0002] In the high-voltage site of the substation, each relatively independent equipment area must be equipped with a drainage ditch and a sewer cover to allow the rainwater to drain out of the station through the drain, and the drainage cover is usually a conventional concrete prefabricated grid structure. There are the following disadvantages: 1.

After the sundries enter the drainage ditch, due to the large site, cleaning needs A lot of manpower and material resources are wasted; 3. The drainage ditch is connected with the cable ditch. Due to the large drain hole of the drainage cover plate, small animals (snakes and mice) may enter the cable ditch through the drain hole of the cover plate, thereby damaging secondary equipment such as cables, causing equipment accident
