[0002] An electrical control box is a combination of equipment used for control, measurement, signaling, protection, and regulation. It typically contains one or more low-voltage switchgear and related equipment.

[0003] Underground electrical control boxes in coal mines are typically made of high-quality alloy steel, which has a robust structure, good mechanical properties, and features such as high airtightness and good corrosion resistance. However, problems such as water ingress and rusting can still occur in control valve boxes. Moreover, due to the high airtightness of underground control boxes, the electrical components inside cannot dissipate heat, and prolonged high-temperature operation will lead to a reduction in the service life of the electrical components. Summary of the Invention

To this end, an embodiment of this utility model proposes an electrical control box, which allows oily coolant to be injected into the box through an inlet. On the one hand, the oily coolant can coat the electrical components to achieve a corrosion-resistant effect; on the other hand, the flow of the oily coolant can cool and dissipate heat from the electrical components, extending the service life of the electrical control box.

[0005] The electrical control box of this utility model embodiment includes a box body, which is used to house electrical components. The box body is provided with a wiring port, a liquid inlet, and a liquid outlet. The liquid inlet is connected to an oily coolant inlet pipe, and the liquid outlet is connected to an oily coolant outlet pipe. The wiring port is used for wiring of the electrical components.

[0006] The electrical control box of this utility model embodiment has a liquid inlet and a liquid outlet on the box body. The liquid inlet is connected to an oily coolant inlet pipe, and the liquid outlet is connected to an oily coolant outlet pipe. Thus, this application can inject oily coolant into the box body through the liquid inlet. On the one hand, the oily coolant can be used to coat the electrical components to achieve a corrosion protection effect. On the other hand, the flow of the oily coolant can be used to cool and dissipate heat from the electrical components, thereby extending the service life of the electrical control box.

[0007] In some embodiments, an inlet connecting pipe is provided at the liquid inlet, and an outlet connecting pipe is provided at the liquid outlet. The inlet connecting pipe is provided with a one-way valve that allows oily coolant to flow into the tank, and the outlet connecting pipe is provided with a one-way valve that allows oily coolant to flow out of the tank.

[0008] In some embodiments, the connection port is a connection hole with a sealing collar.

[0009] In some embodiments, the liquid inlet and the liquid outlet are respectively located on two opposite sides of the housing.

[0010] In some embodiments, the inlet and the outlet are arranged diagonally.

[0011] In some embodiments, one of the liquid outlet and the liquid inlet is disposed adjacent to the top plate of the housing, and the other is disposed adjacent to the bottom plate of the housing.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 and Figure 2As shown, the electrical control box of this utility model embodiment includes a box body, which is used to house electrical components. The box body is provided with a wiring port 3, a liquid inlet and a liquid outlet. The liquid inlet is connected to an oily coolant inlet pipe, and the liquid outlet is connected to an oily coolant outlet pipe. The wiring port 3 is used for wiring the electrical components.

[0022] Understandably, the inlet can deliver oily coolant into the enclosure. The presence of oily coolant in the enclosure prevents water from entering and provides corrosion protection. Furthermore, the oily coolant can flow out from the outlet, keeping the coolant in the enclosure in a flowing state to carry away the heat generated by the electrical components inside the enclosure, thus achieving the cooling function.

[0023] The electrical control box of this utility model embodiment has a liquid inlet and a liquid outlet on the box body. The liquid inlet is connected to an oily coolant inlet pipe, and the liquid outlet is connected to an oily coolant outlet pipe. Thus, this application can inject oily coolant into the box body through the liquid inlet. On the one hand, the oily coolant can be used to coat the electrical components to achieve a corrosion protection effect. On the other hand, the flow of the oily coolant can be used to cool and dissipate heat from the electrical components, thereby extending the service life of the electrical control box.

[0024] Preferably, such as Figure 2 As shown, an inlet connecting pipe 4 is installed at the liquid inlet, and an outlet connecting pipe 5 is installed at the liquid outlet. The inlet connecting pipe 4 contains a one-way valve that allows oily coolant to flow into the tank, and the outlet connecting pipe 5 contains a one-way valve that allows oily coolant to flow out of the tank. Therefore, the connecting pipes are easy to install and remove from external pipelines, and the one-way valves prevent coolant backflow, ensuring corrosion resistance and cooling effect.

[0025] Furthermore, the connection port 3 is a connection hole with a sealing collar. Specifically, electrical components are connected to external power units through the connection port 3, and the sealing collar can wrap around the outer circumference of the wire after the wire is routed, so that there is no gap between the wire and the wall of the connection port 3, thereby achieving a sealing and leak-proof effect to prevent coolant from flowing out.

[0026] In some embodiments, the inlet and outlet are respectively located on two opposite sides of the housing. It is understood that if the inlet and outlet are concentrated on only one side, the coolant flow near the inlet and outlet sides will be better, while the coolant flow in more distant areas will be poor. This does not utilize the overall flow of coolant within the housing, thus affecting the cooling effect. Based on this problem, the oppositely located inlet and outlet help promote the flow of coolant within the housing, further improving the cooling effect.

[0027] Preferably, the inlet and outlet are arranged diagonally. For example, such as Figure 2As shown, the housing has a rectangular structure, and the inlet and outlet can be set at opposite corners of the rectangle to increase the coolant flow path and improve the cooling effect.

[0028] In some embodiments, one of the outlet and inlet is located on the top plate adjacent to the housing, and the other is located on the bottom plate adjacent to the housing. In other words, there is a height difference between the outlet and inlet in the vertical direction. This avoids the problem of the coolant having good surface flow and poor or no flow at the bottom, which helps to improve the overall flow of the coolant in the housing.

[0029] In some embodiments, the enclosure includes a body 1 and a cover 2. The body 1 has a chamber for accommodating electrical components. The cover 2 is connected to the opening of the chamber and can open and close the chamber. A wiring port 3, a liquid inlet, and a liquid outlet are all located on the body 1. It is understood that the cover 2 facilitates the installation and maintenance of electrical components, while concentrating the wiring port 3, the liquid inlet, and the liquid outlet on the body 1 improves the stability of pipe connections and prevents them from being affected by the opening and closing of the cover 2.

[0030] Preferably, a sealing element is provided between the main body 1 and the cover 2. Therefore, the sealing element ensures the airtightness of the entire enclosure when the cover 2 is closed, preventing coolant leakage and ensuring corrosion protection and cooling performance.

[0031] Specifically, a sealing groove 11 is provided at the opening of the cavity, arranged circumferentially around the opening, and the sealing element is disposed within the sealing groove 11. Thus, the sealing groove 11 has a positioning and concealing effect on the assembly of the sealing element, protects the sealing element, and improves the stability of the sealing element assembly.

[0032] Preferably, the cover 2 is coated with an anti-rust layer.

[0033] Furthermore, the main body 1 is also equipped with a valve box grounding 6 to effectively prevent electric shock accidents and equipment damage.

[0034] Furthermore, the main body 1 is also equipped with a mounting bracket, which is used to fix the ground.

[0035] Furthermore, the valve box grounding 6 is located on different sides from the inlet, outlet, and wiring port 3, which avoids assembly interference and improves safety.

[0036] Furthermore, the cover 2 is connected to the top of the body 1, and the connecting bracket 7 is connected to the bottom of the body 1.

[0037] Furthermore, the upper surface of the cover 2 is provided with a cover handle 8, an explosion-proof nameplate 9, a multi-functional valve box nameplate 10, and a safety sign nameplate 11.
