Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, and in particular to a distribution box. Background Art

[0002] A distribution box is a type of electrical equipment, similar to a distribution cabinet, and is mainly used for circuit conversion and control. During the conversion and control of electricity, a large amount of heat is often generated, so a heat dissipation mechanism is usually installed inside the distribution box.

[0003] However, the traditional heat dissipation mechanism only blows air to dissipate heat to the electrical components, filters the air through the filter plate, and then discharges the hot air. The filter plate needs to be replaced frequently manually, and under the negative pressure of wind, the filter cotton of the filter plate is difficult to fall off automatically after accumulating dust. When the dust is thick, it affects the filtering and heat dissipation efficiency. The blown heat is directly discharged, and there is a lack of mechanism for utilizing the heat. When the temperature is low in winter, snow is easy to accumulate on the top of the box. When the snow melts slowly, moisture can easily enter the interior of the box after a long period of infiltration. There is a lack of mechanism for quickly clearing and melting the accumulated snow. At the same time, when the temperature is low, the accumulated water at the bottom of the box evaporates slowly, which can easily cause the bottom of the box to rust. Summary of the invention

[0006] As a preferred technical solution of the present invention, the filter cotton of the filter plate is in a vertically placed wavy structure, and the bottom end of the filter plate is in an inclined shape.

[0007] The above technical solution is helpful to increase the filtering area and facilitate the dust to fall into the inside of the collection tank after being knocked.

[0008] As a preferred technical solution of the present invention, one end of the fixed shell located outside the box body is stepped, and a protective net is installed on one end of the fixed shell located outside the box body.

[0009] By means of the above technical solution, larger floating objects can be intercepted, and at the same time, the stepped fixed shell is easy to disassemble and insert.

[0010] As a preferred technical solution of the present invention, the drying mechanism includes an air duct, and the box body is provided with an air duct, and the air duct is used to connect the bottom end of the box body and the exhaust duct on the same side of the first guide plate. The box body is rotatably connected with a second guide plate for extending the exhaust duct opening, and the second guide plate is used to block the exhaust duct and the air duct, and a connecting rod is rotatably connected between the second guide plate and the pull rod.

[0011] Through the above technical solution, it is convenient to blow air to the bottom of the box, thereby increasing the volatilization of accumulated water.

[0012] As a preferred technical solution of the present invention, an air groove is provided at the bottom end of the box body, and the air groove is connected to the air duct. The cross-section of the air groove is in the shape of a right-angled trapezoid, and the right-angled side of the air groove is close to the air duct. An isolation net is installed at the bottom opening of the box body at the air duct.

[0021] Through the above technical solution, the temperature transfer speed is increased.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a filter plate, a rack and an intermittent gear. When the second fan is working, the cold air outside is filtered through the filter plate and then sucked into the interior of the box. The exhaust end of the second fan blows the impeller to rotate, thereby driving the intermittent gear to rotate, thereby driving the rack to move away from the filter plate. The first spring is compressed, and when the intermittent gear moves to the intermittent opening end, it separates from the rack. The first spring is extended. After accumulating force, the first spring quickly pushes the rack to reset and hits the fixed shell, thereby driving the fixed shell to vibrate. Under repeated knocking and vibration, the dust accumulated on the surface of the filter plate falls into the inside of the collection tank, thereby ensuring the filtering efficiency of the filter plate.

[0024] 2. The present invention provides a memory spring, a first guide plate and a heat conduction block. In winter, when the weather is cold, snow is easy to accumulate on the top of the box. When the outside temperature is low, the temperature of the heat conduction block becomes low, thereby contracting the memory spring. The memory spring pulls the pull rod, thereby driving the first guide plate to rotate downward. When the first fan discharges hot air outward, part of the hot air is introduced into the guide cavity. The guide cavity passes through the top inner layer of the box, thereby facilitating the melting of snow on the top of the box. The hot air passing through the guide cavity is discharged from the exhaust pipe at the other end, thereby preventing snow water from flowing into the box due to long-term snow accumulation on the top, thereby realizing the utilization of the discharged heat and increasing the energy utilization rate.

[0025] 3. The present invention arranges a connecting rod, an air trough and a second guide plate. When the temperature is low, it is difficult for water to dry out after accumulating at the bottom of the box. When the pull rod moves upward, the second guide plate is pulled upward by the connecting rod to rotate, thereby intercepting part of the hot air discharged from the first fan and introducing it to the bottom of the box through the air duct. The cross-section of the air trough is in the shape of a right triangle, which makes it easy to blow the discharged hot air to the bottom of the box, thereby facilitating the rapid evaporation of accumulated water and avoiding rust caused by long-term accumulation of water at the bottom of the box.
