[0002] The low-voltage distribution box is a distribution equipment for low-voltage power systems, which is mainly used to receive, distribute and control electricity. It is widely used in residential, commercial and industrial fields. However, in certain cases, the low-voltage distribution cabinet can be installed outdoors. The current low-voltage distribution box is usually provided with heat dissipation holes, which help to increase the air circulation speed and promote the internal heat dissipation. However, in order to maintain the ventilation inside the low-voltage distribution box, outdoor insects can use these ventilation holes to enter the box, and the insects enter the low-voltage distribution box and contact the live parts, causing safety hazards such as short circuit and leakage. Once a fault occurs, it may affect the normal production of the enterprise and even endanger personal safety. In addition, insects may breed bacteria inside the outdoor low-voltage distribution box, deteriorate environmental hygiene, and affect the image of the enterprise and the working environment of employees. Therefore, the utility model designs a low-voltage distribution box with an insect-proof heat dissipation structure. Utility Model Content

[0028] Example

[0029] like Figure 1-6 As shown, the utility model proposes a low-voltage distribution box with an insect-proof heat dissipation structure, including a box body 1, a pair of mounting frames 5 corresponding to each other and used for mounting equipment are arranged inside the box body 1, and the mounting frame 5 provides stable support for the electrical equipment in the low-voltage distribution cabinet to ensure that the equipment will not shake or tilt during operation, thereby improving the service life and safety performance of the equipment. In addition, the mounting frame is designed with a reasonable space, which makes the installation of the electrical equipment more convenient and convenient for future maintenance and repair work. The box body 1 is connected to a box door 4 through a rotating shaft, and a lock mechanism 6 is arranged on the box door 4. The lock mechanism 6 is a device for ensuring the safety of electrical equipment and preventing misoperation. It is usually composed of a lock body, a key and a locking mechanism. It also includes: a pair of mounting ports 2 for air circulation opened on the box body 1, a heat dissipation mechanism for quickly reducing the temperature in the box body 1 is arranged on the mounting port 2, and an insect-proof mechanism for preventing insects from crawling from the heat dissipation mechanism into the box body 1 is fixedly connected to the inner wall of the box body 1; a rebound mechanism arranged on the heat dissipation mechanism for quickly disassembling and assembling the heat dissipation mechanism in the mounting port 2.

[0030] Further, the heat dissipation mechanism includes a cover 201 installed in the installation port 2, a stopper 202 is fixedly sleeved on the cover 201 for limiting the distance of the cover 201 inserted into the installation port 2, and a plurality of linearly arranged strip heat dissipation holes 206 for heat dissipation are opened at one end of the cover 201 away from the box body 1, and a baffle 205 for covering the strip heat dissipation holes 206 is fixedly connected at one end of the cover 201, and the baffle 205 is used to prevent rainwater from entering the cover 201 from the strip heat dissipation holes 206 after cooperating with the solar panel 203, so as to avoid water seepage. A pair of support blocks 204 are fixedly connected at one end of the cover 201, and the support blocks 204 are rotatably connected with a solar panel 203 for receiving sunlight after blocking the strip heat dissipation holes 206, and the solar panel 203 is a device that converts light energy into electrical energy using the solar photovoltaic effect. Its main component is a solar cell, and the solar cell is made of semiconductor materials, such as silicon, gallium arsenide, etc. When sunlight shines on the solar cell, photons react with electrons in the semiconductor material to generate current. A pair of fan covers 207 corresponding to the strip-shaped heat dissipation holes 206 are fixedly connected to the inside of the cover 201. A plurality of cooling fans 208 arranged linearly and connected to the solar panel 203 are arranged inside the fan cover 207. The wind direction of the cooling fan 208 in one of the covers 201 is toward the inside of the box 1, and the wind direction of the cooling fan 208 in the other cover 201 is toward the outside of the box 1. The cooling fan 208 is connected to the solar panel 203 through a controller.

[0031] The insect-proof mechanism includes an insect-blocking cover 3 connected to the inside of the box 1 for blocking the installation opening 2, and an insect-blocking net 31 for blocking insects from entering the box 1 is provided at opposite ends of a pair of insect-blocking covers 3. The insect-blocking net 31 is made of stainless steel wire mesh, aluminum wire mesh, etc. The metal wire mesh has high hardness, corrosion resistance and wear resistance, and is suitable for harsh environments. In addition, the metal wire mesh can also be electroplated or sprayed to increase its corrosion resistance.

[0032] Furthermore, the rebound mechanism includes a sliding hole 209 provided at one end of the cover 201, a pair of L-shaped telescopic rods 211 are slidably connected inside the sliding hole 209, a pinch block 210 is fixedly connected to the other end of the L-shaped telescopic rod 211, a clamping block 212 for clamping the installation port 2 is fixedly connected to one end of the L-shaped telescopic rod 211, and the normal state of the L-shaped telescopic rod 211 is to automatically clamp the installation port 2. A slider 213 is fixedly connected to the L-shaped telescopic rod 211, and a pair of sliders 213 are provided with a reset spring 214 for pushing and pulling the sliders 213 to restore the original position. The function of the reset spring 214 is that when the pair of pinching blocks 210 are not pinched, the clamping block 212 will automatically clamp the installation port 2.

[0033] In this embodiment, when a low-voltage distribution box with an insect-proof heat dissipation structure is required, such as Figure 4As shown, the solar panel 203 is first rotated upward with the support block 204 as the center, so that the solar panel 203 is separated from the baffle 205. At the same time, the pair of pinching blocks 210 are exposed to facilitate human operation. At this time, the pair of pinching blocks 210 are pinched in the same direction, and then as shown in FIG. Figure 5 As shown, a pair of pinching blocks 210 drives the corresponding L-shaped telescopic rods 211 to slide along the sliding hole 209 in the same direction. At this time, one end of the pair of L-shaped telescopic rods 211 drives the corresponding clamping blocks 212 to retract in the same direction, so that one end of the cover 201 with the clamping blocks 212 can be inserted into the installation port 2, and then the block 202 on the cover 201 is pressed against the outer wall of the box body 1, and then the pinching blocks 210 can be released. At this time, the pair of L-shaped telescopic rods 211 do not receive the binding force, and the elastic thrust can be generated by the return spring 214 set in the middle of the pair of sliders 213, so that the pair of sliders 213 return to the original position. At this time, the pair of L-shaped telescopic rods 211 that have returned to the original position drive the corresponding clamping blocks 212 to clamp the installation port 2 in the opposite direction, and finally the cover 201 is installed in the installation port 2 and cannot be removed; when the cover 201 needs to be removed from the installation port 2, it is only necessary to pinch the pair of pinching blocks 210 in the same direction. The principle is the same as above and will not be repeated here.

[0034] When the low-voltage distribution box needs to dissipate heat, the solar panel 203 uses the photoelectric effect to convert the energy of sunlight into electrical energy, and then the controller receives a signal to activate the fan to start, so that a pair of cooling fans 208 located in the cover 201 can generate airflow. After the cooling fan 208 in one cover 201 is started, it blows out the hot air in the box 1, and the cooling fan 208 in the other cover 201 blows the air outside the box 1 into the box, thereby accelerating the heat dissipation of the electrical components in the box 1. While the low-voltage distribution box is dissipating heat, the insect-blocking net 31 on the insect-blocking cover 3 will prevent insects from crawling into the box 1 from the strip-shaped heat dissipation holes 206, thereby avoiding damage to the electrical components in the box 1.

Obviously, many modifications and changes can be made according to the content of this specification.
