Problems solved by technology
[0002] At present, maintenance personnel need to bend over and squat down when inspecting and maintaining the distribution box, which is extremely inconvenient; if inspection and maintenance needs to be carried out for a long time, the maintenance personnel need to stand or squat for a long time, which is also very physical for the maintenance personnel. Especially in rainy and snowy weather or high temperature weather, the maintenance personnel have nowhere to hide, and it takes more energy for maintenance
[0003] In rainy and snowy days, the opened power distribution box is prone to water ingress, short circuit and low safety; in summer, strong direct light will not only increase the internal temperature of the power distribution box, cause a fire, but also affect the sight of maintenance personnel , causing inconvenience to maintenance

The invention discloses an adjustable distribution box and a protective device thereof. A square plate disposed horizontally and internally disposed in the square housing movable in a vertical direction by a pair of linkage mechanisms; a pair of linkage mechanisms are horizontally spaced between the square plate and the bottom plate of the square housing, and the linkage mechanisms are formed by hinged two links through a pin shaft, wherein the pin shaft is horizontally fixed with a cylinder having an internal thread; a screw rod whose two ends are opposite in thread direction and respectivelythreaded into a pair of cylinders; a power distribution box fixed on the square plate; a sealing plate movably disposed in the horizontal direction on the open surface of the square housing and sealing the open surface of the square housing. The invention has the advantages that the height is adjustable, the maintenance personnel can sit and maintain, the distribution box and the maintenance personnel are shielded and protected, and the invention can be widely applied in the technical field of electric power equipment.
Description
technical field [0001] The invention relates to the technical field of electric equipment. More specifically, the present invention relates to an adjustable distribution box and its protective device. Background technique [0002] At present, maintenance personnel need to bend down and squat down when inspecting and maintaining the distribution box, which is extremely inconvenient; if inspection and maintenance needs to be carried out for a long time, the maintenance personnel need to stand or squat for a long time, which is also very physical for the maintenance personnel. Especially in rainy and snowy weather or high temperature weather, the maintenance personnel have nowhere to hide, and it takes more physical effort for maintenance. [0003] In rainy and snowy days, the opened distribution box is prone to water ingress, short circuit, and low safety; in summer, strong direct light not only increases the internal temperature of the distribution box, causing fires, but al...
