Description
Technical Field
The invention relates to the technical field of high-voltage cable equipment, in particular to an outdoor high-voltage cable distribution box.
Background
Along with the development of distribution network cabling process, when the independent load distribution that capacity is little is more concentrated, can use cable distribution box to carry out the connection of cable multiple branch, because the distribution box can not directly operate every way, only use as cable branch, cable distribution box's main effect is with cable shunting or switching, the cable distribution box of this kind of supplementary usefulness adopts the structure of cuboid or cube, its hexahedron all adopts steel material, except that one side is opened the door, all other five sides all adopt modes such as welding to carry out fixed connection and form the structure of integral type, cable connecting piece installs in the box, be located the box inner chamber with the mode of transversely distributing. The cable distribution box has the following defects in the using process: firstly, when the box is used, because the box is in the open air, the dust is more, and the box wall is vertical, when raining or humidity is too big, water drops or water flow are difficult to flow on the box wall, also can't wash the box wall, and the time is long, and the continuous cover of dust combines with water, easily damages the box wall under the effect of electrochemistry, because the integral type structure of box leads to changing needs box whole change, therefore the change time is long, when involving accessories such as inside cable connecting piece, it is more complicated and inconvenient.
Disclosure of Invention
The invention aims to provide an outdoor high-voltage cable distribution box, and aims to solve the problem that the outdoor high-voltage cable distribution box in the prior art cannot be self-cleaned after dust is attached.
The outdoor high-voltage cable distribution box comprises a box body, wherein a top cover is arranged at the top of the box body, four sides of the top cover are protruded relative to the box body, the box body comprises an upper box body and a lower box body, the upper box body and the lower box body are of a regular quadrangular frustum structure which is integrally formed, an included angle between the side surface of the regular quadrangular frustum and a vertical surface is 5-10 degrees, a connecting plate is vertically arranged between the upper box body and the lower box body, and a plurality of heat dissipation windows are arranged on the connecting plate; the two opposite sides of the upper box body are provided with box doors, the box doors are hinged to the top cover, sealing strips are arranged at openings of the box doors and the upper box body, water receiving grooves are formed in the bottoms of the upper box body and the lower box body in a surrounding mode, at least 4 flat drainage tubes communicated with the water receiving grooves are arranged on the inner box wall of the lower box body, one ends of the drainage tubes are communicated with the water receiving grooves of the upper box body, the other ends of the drainage tubes are communicated with the water receiving grooves of the lower box body, and water receiving grooves of the lower box body are communicated with water.
According to the outdoor high-voltage cable distribution box, a box body is changed into a box body formed by combining two square-edged tables which are arranged up and down, the two square-edged tables are connected together through a connecting plate, and a plurality of heat dissipation windows on the connecting plate are used for dissipating heat. Because the side of positive quadrangular frustum pyramid and the contained angle of vertical face are 5 ~ 10, because the tank wall has less inclination, so the rainwater can form rivers on the tank wall when rainy day, can wash the dust on the tank wall of last box and lower box, avoid the dust to stop on the tank wall, and the rivers that form flow into the water receiving tank again, communicate through flat drainage tube between the water receiving tank on the last box and the water receiving tank of lower box, the drainage tube is fixed on the tank wall down, when the water in the water receiving tank on last box flows into in the drainage tube, can also carry out the heat transfer to the internal environment of distribution box, reduce the temperature of cable distribution incasement, improve power consumption safety and power consumption life, the water receiving tank of lower box bottom passes through the outlet and discharges water.
The invention has the beneficial effects that: according to the invention, the box body is set into two regular quadrangular frustum pyramid boxes, the included angle between the side surface of each regular quadrangular frustum pyramid and the vertical surface is 5-10 degrees, dust is not easy to adhere at the included angle, and rainwater can form water flow on the box wall even if part of dust adheres to the box wall, so that the box wall adhered with the dust is washed, the purpose of self-cleaning is achieved, the service life of the box body is prolonged, and meanwhile, the water flow can flow in the box through the drainage pipe between the upper water collecting tank and the lower water collecting tank, so that the temperature in the box is reduced.
The chamber door sets up on last box and is articulated with the top cap, opens the case and can carry out the components and parts of incasement and overhaul and change, closes the chamber door when not using, because the opening part of chamber door and last box is provided with the sealing strip, avoids water or other fluids to flow into the incasement.
Further, a handle is arranged on the box door and is made of silicon rubber materials. The arrangement of the handle is convenient for opening the box door, and the silicon rubber material is not easy to damage when used in the outdoor environment.
Furthermore, eight drainage tubes are arranged on the side walls of the lower box body respectively, and two drainage tubes are fixedly connected to each side wall. Set up eight drainage tubes and divide and establish under on the lateral wall of box, every lateral wall is fixed to be set up two, increases the speed of drainage, improves heat transfer area simultaneously.
Furthermore, each heat dissipation window is provided with at least two strip-shaped heat dissipation holes, and downward-inclined blocking pieces are arranged on the heat dissipation holes. Increase heat radiating area, the separation blade of slope prevents the rainwater entering simultaneously, in addition, because the connecting plate is the indent for last box, so is more difficult to be got into by the rainwater.
Furthermore, moisture absorption silica gel is arranged on the separation blade. Moisture absorption silica gel can absorb the moisture in the box, and power utilization accidents caused by humidity are avoided.
Furthermore, a transparent observation window is arranged on the upper box body, and a humidity color-changing card is arranged in the box and in the view field range of the observation window. The observation window can look at the components and parts in the case, sets up humidity color-changing card simultaneously, the humidity of the observation box internal environment of branch pipe of being convenient for to take remedial action.
Preferably, the included angle between the side surface of the regular quadrangular frustum pyramid and the vertical surface is 5 degrees.
Preferably, the included angle between the side surface of the regular quadrangular frustum pyramid and the vertical surface is 10 degrees.
The smaller the included angle is, the less the dust is easy to stay, but the less the dust is easy to form water flow, and the larger the included angle is, the more the water flow is easy to form, so that the optimum included angle is 10 degrees in comprehensive consideration.
