Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box capable of preventing snow and ice from accumulating. Background Art

[0002] In daily life, most common substations are box-type substations, which are often installed outdoors. When used in the north, due to the cold winters in the north and extreme weather such as heavy snow, ice and snow will accumulate on the outdoor substations, posing a hidden danger to electricity use.

[0003] Currently, most cleaning methods are manual. When removing snow and ice at substations, most people need to use shovels and brooms to clean up the snow and ice. The workload is large and the efficiency is average. In addition, manual processing has periodicity and lags, and it is impossible to eradicate hidden dangers. Utility Model Content

The top of the distribution box is an inclined top surface, and the front side is closed by a hinged door. The side wall of the distribution box is protruded upward with a fixed convex plate, and a bending shaft is connected between the left and right fixed convex plates. The angle of the inclined part of the bending shaft is consistent with the inclined top surface. Front and rear side notches are opened on the front and rear sides of the top scraper, and the bending shaft passes through the front and rear side notches. The top scraper is made of iron material Its initial position is located at the center of the inclined top surface, and it moves under the action of the scraper drive. When it moves under the action of the scraper drive, due to the cooperation of the front and rear side notches and the bending axis, it can ensure that the scraper moves stably along the inclined top surface, pushing down the snow accumulated on it to avoid excessive accumulation. An internal heat dissipation fan is installed inside the distribution box, and a heat dissipation channel is connected at its hot air outlet. The heat dissipation channel is connected to the side wall antifreeze structure of the side wall of the distribution box, and the heat generated during the operation of the distribution box is transferred to the side wall antifreeze structure to avoid ice on the side outer wall. A mounting plate is fixed in the distribution box, on which a number of through grooves are opened, and a working unit is arranged on it. The working unit generates heat when working.

[0005] As an optimal technical solution of the utility model, the scraper drive includes a lead screw and a magnetic plate. The lead screw is rotatably installed in the cavity at the top of the distribution box. The lead screw is driven by a small motor built into the side wall of the cavity. The motor is powered by a rechargeable battery. The top surface inside the cavity is parallel to the inclined top surface. The inclination angle of the lead screw is the same as the angle of the inclined top surface. The upper surface of the magnetic plate is in contact with the top surface of the cavity and is installed in conjunction with the lead screw. The motor operates regularly through the setting of the controller. When it runs, it drives the lead screw to rotate and the magnetic plate moves in the cavity. Under the action of strong suction, it will drive the top scraper to move with it to achieve scraping of the inclined top surface.

[0006] As a preferred technical solution of the utility model, the side wall antifreeze structure includes an inner chamber, a through hole, an outer chamber, an outer chamber side wall mounting groove and a heat absorbing rod. The side wall of the distribution box is divided into an inner chamber and an outer chamber. A number of through holes are evenly distributed on the side wall of the inner chamber. The side wall of the outer chamber is provided with an outer chamber side wall mounting groove and a heat absorbing rod is installed therein. The position of the through hole corresponds to the position of the heat absorbing rod. The heat generated by the work in the distribution box is blown out from the through hole to the heat absorbing rod, causing its temperature to rise, thereby making the outer wall panel of the distribution box have a certain temperature to prevent the outer wall from freezing.

[0007] As a preferred technical solution of the utility model, the heat absorbing rod is made of ceramic material. By using this material, the heat absorbing effect is good and the heat dissipation is slow, which can meet the technical requirements.

[0008] As a preferred technical solution of the utility model, the outer chamber is connected to the outside through a side ventilation channel, and a one-way valve is provided in the side ventilation channel, so that the air flow can only flow from the inside to the outside.

[0009] The beneficial effects of the utility model are as follows: the top scraper can be driven to move regularly along the inclined top surface through the scraper drive, so as to clear the possible deposits and snow on the inclined top surface to avoid excessive accumulation; the heat generated by the work is transmitted to the inner chamber through the internal heat dissipation fan and the heat dissipation channel and collected to the heat absorbing rod through the through hole, so that the outer wall of the distribution box has a certain temperature to avoid freezing, thus eliminating safety hazards from the root, and no manual cleaning is required on a regular basis, thereby reducing the labor burden.
