Description

Technical Field

[0001] The utility model relates to the technical field of electrical boxes, in particular to an electrical box body. Background Art

[0002] The electrical components such as instruments loaded in the electrical box will continuously generate a large amount of heat during operation. The accumulation of heat will cause the temperature inside the electrical box to be too high, causing the components to trip or overheat and fail.

[0003] However, in the prior art, the auxiliary heat dissipation mechanism of the electrical box is driven by a small motor, which also generates heat, increasing the heat inside the electrical box to a certain extent. At the same time, as time goes by, the filter of the electrical box may be clogged, which greatly reduces the heat dissipation efficiency and increases the risk of failure. For this reason, we propose an electrical box. Utility Model Content

[0004] The utility model provides an electrical box body, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems with the following solution: an electrical box, comprising a box, side walls on both sides of the box are respectively transversely fixed with mounting tubes, the two mounting tubes are staggered up and down, a connecting shaft is transversely arranged in the mounting tube, the outer wall of the connecting shaft is rotatably sleeved with a fixing frame fixedly connected to the inner wall of the mounting tube, the connecting shaft is connected to a driving mechanism, a filter screen movably sleeved on the outer wall of the connecting shaft is threadedly installed on the inner wall of the mounting tube, a fan blade fixedly sleeved on the outer wall of the connecting shaft is arranged in the filter screen, the outer wall of the filter screen is slidably matched with a Y-shaped cleaning piece, and the cleaning piece is threadedly installed on the end of the connecting shaft.

[0006] Preferably, the driving mechanism includes a small motor fixedly mounted laterally on the outer wall of the box body, the output shaft of the small motor and the outer wall of the connecting shaft are respectively fixedly sleeved with pulleys, and the two pulleys are connected by a belt drive that movably penetrates the mounting cylinder.

[0007] Preferably, a protection frame is fixedly mounted on the lower surface of the mounting tube, the protection frame surrounds the small motor, and the lower portion of the protection frame is open.

[0008] Preferably, a handle is fixedly mounted on the edge of the outer wall of the filter screen.

[0009] Preferably, the cleaning member is slidably matched with the side wall of the filter screen, and the cross-section of the cleaning member is wedge-shaped.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting a small motor to indirectly drive the fan blades to rotate, the heat dissipation efficiency of the device is improved. At the same time, the two installation cylinders are staggered up and down, so that the gas can flow through most areas of the box, which can take away more heat and achieve a more ideal heat dissipation effect. At the same time, the small motor is set outside the box, which can reduce the heat generation in the box and is more conducive to the heat dissipation of the small motor;

[0012] 2. A threaded filter is provided with a handle for easy disassembly and cleaning, and a cleaning piece that rotates synchronously with the connecting shaft is provided. The cleaning piece can clean the dust and debris attached to the surface of the filter to ensure its smooth flow.

It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0022] Example 1

[0023] like Figure 1-4 As shown, the utility model is an electrical box, including a box 1, side walls on both sides of the box 1 are respectively fixed with mounting tubes 2 transversely, and the two mounting tubes 2 are staggered up and down, so that the airflow passes through most areas in the box 1 and dissipates heat evenly. A connecting shaft 3 is transversely arranged in the mounting tube 2, and a fixing frame 4 fixedly connected to the inner wall of the mounting tube 2 is rotatably sleeved on the outer wall of the connecting shaft. The connecting shaft 3 is connected to a driving mechanism, and a filter screen 5 movably sleeved on the outer wall of the connecting shaft 3 is threadedly installed on the inner wall of the mounting tube 2. A handle is fixedly installed on the edge of the outer wall of the filter screen 5, and a handle is provided to facilitate the removal and cleaning of the filter screen 5 by rotating the handle. The filter screen 5 is provided with a fixed sleeve on the outer wall of the connecting shaft 3. The fan blades 6 and the outer wall of the filter 5 are slidably matched with a Y-shaped cleaning piece 7, the cleaning piece 7 is threadedly installed at the end of the connecting shaft 3, the cleaning piece 7 is slidably matched with the side wall of the filter 5, the cross-section of the cleaning piece 7 is wedge-shaped, and the tightening direction of the cleaning piece 7 is the same as the rotation direction of the output shaft of the small motor 8, so that the cleaning piece 7 will not loosen. The device indirectly drives the fan blades 6 to rotate by arranging a small motor 8, promotes air convection inside and outside the box 1, and accelerates heat dissipation. At the same time, the small motor 8 is arranged outside the box 1, and less heat is generated in the box 1, which is also beneficial to the heat dissipation of the small motor 8. The cleaning piece 7 is used to automatically clean the filter 5, thereby reducing the adhesion and clogging of dust and debris on the filter 5, which is convenient and practical.

[0024] Example 2

[0025] like Figure 1-4 As shown, the driving mechanism includes a small motor 8 which is laterally fixedly installed on the outer wall of the box body 1, and the output shaft of the small motor 8 and the outer wall of the connecting shaft 3 are respectively fixedly sleeved with pulleys 9, and the two pulleys 9 are connected by a belt 10 that movably penetrates the mounting tube 2. The small motor 8 drives the pulley 9 directly connected thereto to rotate, and indirectly drives the fan blades 6 on the connecting shaft 3 to rotate through the transmission of the pulley 9 and the belt 10, thereby accelerating the air flow and making the heat in the box body 1 dissipate faster. A protective frame 11 is fixedly installed on the lower surface of the mounting tube 2, and the protective frame 11 surrounds the small motor 8. The lower part of the protective frame 11 is open, and the protective frame 11 is used to protect the small motor 8. The small motor 8 is arranged outside the box body 1, which can reduce the generation of heat in the box body 1, and is also conducive to the long-term operation of the small motor 8.

[0026] Working principle:

[0027] When in use, the small motor 8 is controlled to start, and the small motor 8 drives the pulley 9 directly connected thereto to rotate. The pulley 9 drives the pulley 9 on the connecting shaft 3 to rotate through the belt 10, so that the connecting shaft 3 rotates synchronously. The connecting shaft 3 drives the fan blades 6 and the cleaning piece 7 to rotate synchronously. The rotation of the fan blades 6 accelerates the air flow, promotes the internal and external air convection, and accelerates the heat loss. The cleaning piece 7 rotates to continuously and automatically clean the outer surface of the filter 5, sweeps away the attached dust and debris, and ensures the smooth flow of the filter 5.
