Description
Technical Field
[0001] The utility model is applicable to the technical field of box-type substations, and particularly relates to an electric shock-proof box-type substation. Background Art
[0002] At present, the box-type substation, also known as prefabricated substation or prefabricated substation, is a factory-prefabricated indoor and outdoor compact distribution equipment that is composed of high-voltage switchgear, distribution transformers and low-voltage distribution devices arranged in one according to a certain wiring scheme.
[0003] However, when inspecting and using the box-type substation nowadays, the maintenance personnel often pull the box door on the front side of the box-type substation to open it, and then inspect the inside through the corresponding open position. When it rains outside, the rain shielding mechanism on the top of the box-type substation cannot be used for the external rainfall and the different body shapes of the maintenance personnel. The rain shielding mechanism with a simple functional structure cannot fully protect against rain, which causes the rain to easily drift from the front open position to the inside of the box when it falls, causing the electrical components inside the box to be short-circuited and damaged, causing the maintenance personnel to be in danger of electric shock. Therefore, we propose an anti-electric shock box-type substation. Utility Model Content

A pushing spring is movably sleeved on the middle end of the hollow plate, and the side of the pushing spring is movably fitted to the outer surface of the pushing plate.
[0009] By adopting the above technical solution, through the structural action of the sliding rain shield and the movable rain shield, and the pushing action of the push spring on the movable rain shield, the rain shield area of the awning can be protruded and increased, thereby preventing rainwater from passing through the open space of the box door and drifting into the interior of the box to cause damage, while facilitating maintenance personnel of different body sizes to carry out maintenance work on the interior of the box in a rainy environment.
[0010] As an optional scheme of the technical scheme of the present application, a transmission frame is fixedly installed on the side surface of each of the limit baffles away from the sliding rain shield, a rotating screw is rotatably installed inside each of the transmission frames through a bearing, a transmission sleeve is movably sleeved on the side surface of each of the rotating screws, a fixed block is fixedly installed on the outer surface of each of the transmission sleeves, and the fixed block is slidably installed inside the transmission frame and the side of the limit baffle, and one end of the fixed block away from the transmission sleeve is fixedly connected to the outer surface of the sliding rain shield.
[0011] By adopting the above technical solution, the power required for the movement of the sliding rain shield can be provided through the rotational transmission action of the rotating screw on the transmission sleeve.
[0012] As an optional solution of the technical solution of the present application, a servo motor is fixedly mounted on the inner surface of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer surface of the rotating screw through a coupling.
[0013] By adopting the above technical solution, the power source required for rotating the screw rod can be realized through the driving structure of the servo motor.
[0014] As an optional solution of the technical solution of the present application, a rain guide plate is fixedly installed on the surface of one side of each movable rain shield away from the sliding rain shield.
[0015] By adopting the above technical solution, the flowing rainwater can be drained through the structural function of the rain guide plate, so as to prevent the rainwater from scattering arbitrarily and affecting the electrical components inside the box.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The technical solution of the present application is a box-type electric shock protection substation, in which a sliding rain shield is slidably installed on the top of the rain shield, and a hollow plate and a relatively movable rain shield are arranged on the side of the sliding rain shield, so that when the sliding rain shield slides out from the surface of the rain shield, the movable rain shield loses the resistance and limiting treatment of the limit baffle on it, and under the pushing action of the pushing spring on the pushing plate, the two groups of pushing plates can be synchronously and relatively moved horizontally inside the hollow plate, and then under the transmission action of the transmission block, the corresponding horizontal relative driving force is provided to the movable rain shield, so that the movable rain shield can extend from the two ends of the front side of the sliding rain shield, and then combined with the protrusion of the sliding rain shield and the movable rain shield, the rain shield area of the rain shield is increased, so as to prevent rainwater from penetrating the open space of the box door and drifting into the box body to cause damage, while facilitating maintenance personnel of different body sizes to perform maintenance and treatment on the inside of the box in a rainy environment.

This improves the automatic adjustment of the entire device and facilitates the operator to quickly adjust the position of the sliding rain shield and the movable rain shield.
