Problems solved by technology

Manual inspection requires manpower to open the heavy cable trench cover to carry out temperature measurement inspections. Most cable trenches are not waterproof, fireproof, and have insufficient ventilation. It will cause personal injury to the surrounding people, therefore, a device that can replace manual inspection of cable trenches is needed

Embodiment 1

[0043] Such as figure 1 As shown, upwardly opening chute 410 is provided on both sides of the upper part of the track, and fixed rods 420 are arranged at intervals in the middle of the two chute 410 , and the upper ends of the fixed rods 420 are used to connect with the bottom of the cover plate 610 . The overall shape of the track is a strip-shaped block, and a chute 410 is provided along its length direction, and the opening on the top of the chute 410 is used for inserting rollers. A section of track at the bottom of all cover plates is spliced ​​into a long track. The lengthwise direction of the fixed rod 420 is perpendicular to the lengthwise direction of the track. Flanges can be set on the upper end of the fixed rods and through holes can be provided on the flanges, and the cable groove cover plate 610 is fixed by screws. At the same time, there is a gap where the rollers can be placed between the track and the bottom of the cable trench cover.

[0044] The inspection...

Embodiment 2

[0049] The track includes permanent magnets 510 installed on the lower part of the cover plates, at least four permanent magnets are arranged on the lower part of each cover plate, and the permanent magnets are arranged in two rows. The cable trench cover plates are arranged adjacent to and connected to cover the cable trench. The permanent magnets located at the lower part of the cover plate form continuous dot-shaped tracks when the cover plates are continuously arranged, thereby forming a robot that can absorb the inspection robot and assist the inspection. Check the track on which the robot moves. The moving mechanism includes a first suction assembly 501 and a second suction assembly 502 arranged up and down, and the first suction assembly 501 and the second suction assembly 502 are rotationally connected by a steering gear 520 . The two adsorption components can generate any turning angle through the steering servo, and then the steering at the intersection of the cable ...

Abstract

The invention relates to the field of power system operation and maintenance, in particular to a wireless sensor type cable trench comprehensive early warning device and method. The device is provided with a controller, a power supply module, a sensing acquisition module and a data transmission module on the body of the inspection robot. The sensing acquisition module includes an electric telescopic rod and a probe holder, one end of the electric telescopic rod is connected to the inspection robot body, the telescopic end of the electric telescopic rod is fixedly connected to the probe holder, and the probe holder is provided with Sensors are used to collect information. The probe of the present invention can reduce the disturbance of internal gas when running at a slow speed and installed on the telescopic mechanism, and accurately measure the content of each gas in the environment. At the same time, a method for deep early warning of potential faults in cable trenches is disclosed, using the above-mentioned device to make early warnings of faults through the collection and analysis of environmental information and electrical information.

Description

technical field [0001] The invention relates to the field of power system operation and maintenance, in particular to a wireless sensor type cable trench comprehensive early warning device and method. Background technique [0002] The cable trench is an underground pipeline or channel for laying power or communication cables, and it is also the outer protective structure of the cable facilities. With the continuous development of cities, substation cable trenches and cable half-layers have been widely used in power grid construction due to their advantages of small footprint and high concealment. However, at present, the inspection work of the cable trench is often completed manually, and the operation of the cable and the environment of the cable are inspected by means of manual inspection. Manual inspection requires manpower to open the heavy cable trench cover to carry out temperature measurement inspections. Most cable trenches are not waterproof, fireproof, and have in...
