Description

Self-moving waterproof power distribution cabinet

Technical Field

The invention relates to the technical field of power distribution cabinets, in particular to a self-moving waterproof power distribution cabinet.

Background

The power distribution cabinet can be divided into final-stage equipment of power distribution systems such as a power distribution cabinet, a lighting power distribution cabinet and a metering cabinet, and is mainly applied to various different occasions such as power plants, transformer substations, petrochemical industry, metallurgical steel rolling, light industrial textiles, industrial and mining enterprises, residential districts and high-rise buildings. Outdoor switch board is installed in order to supply with city electric power demand in the city in the road both sides, it is used for ventilation cooling to have seted up the air-inlet grille on the lateral wall all around of outdoor switch board, and in rainy day, it is internal that the rainwater is very easily got into the cabinet by the air-inlet grille, and when the rainfall is great, it has a large amount of ponding to converge on the urban road, ponding easily permeates to the switch board inside from the gap of switch board bottom, cause electrical equipment to receive damp short circuit, the electrical coil, the insulation aging of lead wire punctures and burns out the scheduling problem, influence the stability of electrical apparatus protection performance, the reliability of action, the accuracy of measurement, current solution is to erect higher base in order to improve the height of switch board, and the higher switch board in position is influenced by wind-force more greatly, life in the region of strong wind throughout the year is shorter.

For solving the aforesaid and having the problem, the outdoor switch board of formula of moving certainly among the prior art prevention of seepage can use, but still there is certain drawback in the in-service use in-process, for example the inflation elevating system rationality of the cabinet body below is lacked to some extent, because rainy weather's season is different, and the difference of south north temperature, when the cabinet body meets overcast and rainy day water level rebound, make the guarantee nature of the internal portion loading board position of cabinet portion rebound relatively poor, ponding enters into the internal portion of cabinet and causes electrical equipment to wet the short circuit, electric coils, the insulating ageing of lead wire punctures the probability of burning out and is still higher, be unfavorable for using widely.

Disclosure of Invention

The invention aims to provide a self-moving waterproof power distribution cabinet, which solves the problems that the rationality of an expansion lifting mechanism below a cabinet body in the background technology is insufficient, the guarantee that a bearing plate moves upwards in the position of the cabinet body is poor due to different seasons in rainy weather and the difference of temperatures in the south and north, accumulated water enters the interior of the cabinet body to cause damp and short circuit of electrical equipment, the probability of breakdown and burning of electrical coils and leads due to insulation aging is still high, and the popularization and the use are not facilitated when the cabinet body moves upwards in water level in rainy days.

In order to achieve the purpose, the invention provides the following technical scheme: a self-moving waterproof power distribution cabinet comprises a base, wherein a cabinet body is fixedly connected above the base, a bearing plate is arranged below the cabinet body, four corners of the lower surface of the bearing plate are tightly abutted with lugs, the lugs are fixedly connected with the contact surface of the cabinet body, and an expansion lifting mechanism is arranged below the bearing plate;
