Automatic opening machine for cable trench cover plate of transformer substation

Abstract

An automatic opening machine for a cable trench cover plate of a transformer substation comprises a support installed at an opening of a cable trench, the support is provided with the cover plate covering the opening of the cable trench, one end of the cover plate is hinged to the support, the support is provided with a driving device driving the cover plate to be opened and closed, and the support is provided with a signal receiver located on the lower portion of the cover plate. The device further comprises a rainwater sensor arranged in the area nearby an opening of the cable trench, the signal receiver is in communication connection with the rainwater sensor, the signal receiver is in communication connection with the driving device, a solar cell panel is arranged on the upper surface of the cover plate, and a storage battery located on the lower portion of the cover plate is installed on the support. The storage battery is electrically connected with the solar cell panel, the signal receiver and the driving device. The cover plate can be automatically opened and closed according to the cable trench and weather conditions, airing of the interior of the cable trench is achieved, the labor intensity of workers is reduced, and the cable trench is safer to use.

Description

technical field [0001] The invention belongs to the technical field of drying cable trenches, in particular to an automatic opening machine for cable trench cover plates in substations. Background technique [0002] In the daily work of cable trenches in substations, it is necessary to ensure that the environment in the cable trenches is dry. Now most of them need to manually open the moisture in the drying trenches. [0003] Manual opening is time-consuming and labor-intensive; after rain and snow, the operation and maintenance personnel need to ventilate and dry the cable trench. Since the cable trench cover of the substation is heavy (average 80kg), opening the cover requires at least two people to lift it. The cable trench in the 500kV substation is very long, and the average number of covers per station is 60 and the positions of the covers are scattered, so a large number of ventilation covers need to be manually opened. At the same time, in order to ensure a good ven...

Problems solved by technology

At the same time, in order to ensure a good ventilation and drying effect, the ventilation working time of the cover plate is generally 4.5 hours (including the opening and closing time), and the workload of the cover plate ventilation is heavy, which affects the normal development of inspection and maintenance work on the day
