Embodiment 1

[0044] Such as figure 1 , figure 2 As shown, the cable trench structure that is beneficial to slow down cable corrosion includes a channel 1, the top of the channel 1 is provided with a top cover 8, and the inner wall of the channel 1 is provided with a cable support 2, and the cable support 2 includes A fixed plate 21, the fixed plate 21 is connected to the inner wall of the channel 1 by bolts, the fixed plate 21 is provided with a support plate 22, the side wall of the channel 1 is provided with an interlayer 3, and the inner side of the interlayer 3 The wall is provided with a number of ventilation holes 31 for connecting the channel 1 and the interlayer 3, the interlayer 3 is provided with a number of drying plates 4, the drying plates 4 are filled with desiccant, and the drying plates 4 are upward convex The desiccant is a bagged structure, the bag is made of ventilated fabric, the desiccant is packed into the bag, and then the bag is laid flat on the drying plate 4. Th...

Embodiment 2

[0046] Such as figure 1 , figure 2 As shown, the present embodiment is based on Embodiment 1. Several first humidity sensors are arranged in the interlayer 3, and several second humidity sensors are arranged in the channel 1, and a ventilation duct 5 communicating with the interlayer 3 is also included. The ventilation duct 5 is provided with a fan 6, and the fan 6 is used for deriving the airflow in the interlayer 3, and also includes a controller;

[0047]The first humidity sensor and the second humidity sensor are used to sense the humidity inside the interlayer 3 and the inside of the channel 1 in real time respectively, and transmit the sensed humidity signal to the controller;

[0048] The controller receives the humidity signal and makes an analysis to judge whether to open the fan 6;

[0049] After the fan 6 receives the instruction from the controller, it will automatically open and export the airflow in the interlayer 3;

[0050] It also includes a terminal, whic...

Embodiment 3

[0052] Such as figure 1 , figure 2 As shown, this embodiment is based on Embodiment 1, the support plate 22 is arranged obliquely, the high end of the support plate 22 is the end connected to the fixed plate 21, and the low end of the support plate 22 is provided with a baffle plate 23, so The support plate 22 is a hollow structure, and the side wall of the support plate 22 is provided with a number of through holes, and the fixed plate 21 is provided with communication holes for connecting the support plate 22 and the ventilation holes 31; the support plate 22 is Square structure, the upper end of the square structure is recessed downward to form a groove 26, the bottom of the baffle plate 23 is fixed on the lower end of the groove 26; a reinforcing plate is arranged between the bottom of the support plate 22 and the fixing plate 21 25.

Abstract

The invention discloses a cable trench structure beneficial for slowing down cable corrosion, comprising a trench, the top of the trench is matched with a top cover, the inner wall of the trench is provided with a cable support, and the side wall of the trench is provided with an interlayer , the inner side wall of the interlayer is provided with a number of ventilation holes for connecting the channel and the interlayer, and a plurality of drying plates are arranged in the interlayer, and the drying plates are filled with a desiccant. In the present invention, an interlayer is arranged on the side wall of the channel, and a desiccant is arranged in the interlayer. At the same time, a ventilation hole is arranged on the inner side wall of the channel, and the moist air flow in the channel through the ventilation hole is introduced into the interlayer, reducing the humidity in the channel, and can alleviate the damage of the cable. Corrosion, solves the problem that the existing cable trench is easy to aggravate cable corrosion in humid environment.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a cable trench structure which is beneficial for slowing down cable corrosion. Background technique [0002] The cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities, and it is also an enclosure structure for the cable facilities to be laid. There are rectangular, circular, arched and other pipeline structures. [0003] The cable trench is a trench with a cover, and a cable support is installed in the cable trench. The cable support is usually made of metal material and fixed on the trench wall by welding or screws. The cables are supported by brackets and kept at a certain distance from the bottom of the trench; fire prevention measures are usually taken for cables in the cable trench, including painting fireproof paint, sealing and isolation, etc. [0004] Depending on the number of cables to be...
