Both side walls inside the first installation cavity are provided with mounting plates, and a main control board is installed at the front ends of the two mounting plates.
[0003] The disadvantage of this technology is that the mounting plates inside the box body can only play a role in fixing components, and cannot buffer and protect the components, reducing the damage rate of components under high-frequency vibration of the box body. Content of the Utility Model
[0004] To solve the above problems, the utility model provides a sealed main control box of a mine explosion-proof and intrinsically safe spray dust reduction device.
[0005] The technical solution of the utility model is as follows:
[0006] A sealed main control box of a mine explosion-proof and intrinsically safe spray dust reduction device includes a box body. The box body is provided with a first installation cavity and a second installation cavity. Installation bases are arranged in both the first installation cavity and the second installation cavity. The installation base includes an installation end face. A plurality of groups of installation holes are arranged on the installation end face. Support plates are arranged on both sides of the installation end face. Connecting plates are arranged at the ends of the support plates far away from the installation end face.
[0007] To ensure the structural strength of the installation base, the installation end face, the support plates, and the connecting plates are an integral metal plate.
[0008] To dissipate heat from the heat-generating parts of the components and ensure their normal operation, heat dissipation through holes are arranged on the installation end face, and a heat dissipation fan is arranged on the back side of the installation end face opposite to the heat dissipation through holes.
[0009] To increase the safety of external connection lines, a plurality of explosion-proof connectors are arranged on both sides of the box body.

The partition plate is a double-layer plate, and a plurality of strip-shaped plates are welded between the two layers.
[0015] The beneficial effects of the present utility model are as follows:
[0016] 1. The utility model relates to a sealed main control box of a mine explosion-proof and intrinsically safe spray dust reduction device. The box body is designed in an explosion-proof manner, which greatly increases the structural strength of the box body and the protection effect on internal components. Installers can install precision components such as the main control board and controller in the first installation cavity, and install components with larger volume and weight such as the power supply in the second installation cavity, so as to achieve the partition installation of various components, which is convenient for later maintenance and repair. In addition, when the box body is violently impacted, components such as the power supply with larger volume and mass will not cause secondary damage to precision components such as the main control board and controller, greatly reducing the damage rate of each component when the box body bears a violent impact and ensuring the normal operation of each component in the face of a violent impact. The installation end face is used to install components such as the main control board, controller, and power supply. For the convenience of installation, several groups of installation holes are provided on the installation end face, and the positions of the installation holes are adapted to the positions of each component. Support plates are provided on both sides of the installation end face. The support plates are used to support the installation end face to a position 5-10 cm away from the inner wall of the box body. The support plates are elastic. When the box body shakes violently due to a violent impact, the support plates can keep the components installed on the installation end face in a relatively stable posture, reduce the vibration of the components, and then effectively shock-absorb and buffer the components, greatly reducing the resonance of the components, and further reducing the damage rate of each component in the high-frequency vibration state of the box body, ensuring the normal operation of each component. A connecting plate is provided at one end of the support plate away from the installation end face. The connecting plate is used to connect the inner wall of the box body. The connection method between the two can be mechanical connection such as bolts or welding. Through the setting of the connecting plate, the contact area with the inner wall of the box body can be increased, thereby increasing the stability of the support of the installation base. The installation end face, support plate, and connecting plate are an integral metal plate, which can be specifically formed by die-casting a whole metal plate to ensure the overall structural strength of the installation base.
[0017] 2. Through the setting of the partition plate, the box body can be supported and reinforced, and the compressive capacity of the box body can be increased. To ensure the structural strength of the partition plate, the partition plate is a double-layer plate, and several strip-shaped plates are welded between the two layers of plates.
[0018] 3. The position of the heat dissipation through holes corresponds to the heat generation parts of the components. Through the setting of the heat dissipation through holes and the heat dissipation fans, the components can be efficiently cooled, thereby ensuring the stability of the operating state of the components.
[0019] 4. Through the setting of the explosion-proof joint, it is beneficial to ensure the safety of the external circuit and the stability of the connection of the circuit nodes, and avoid phenomena such as short circuits in the circuit from affecting the normal operation of the external equipment.
[0020] 5. It is used to increase the signal strength of such components for signal transmission and reception through the antenna, ensuring the accuracy and sensitivity of wireless control. When wireless signals need to be transmitted and received, the antenna is pushed out along the telescopic groove by extending the telescopic driving mechanism, and the signal transmission and reception end of the antenna is extended out of the box body to further ensure the quality of the antenna's signal transmission and reception. When there is no need to transmit and receive signals, the antenna is retracted into the box body along the telescopic groove by the telescopic driving mechanism to protect the antenna.
[0021] 6. The first door panel and the second door panel can be used to close the first installation cavity and the second installation cavity respectively. The sealing rubber sleeve can further enhance the sealing effect of the first door panel on the first installation cavity and the second door panel on the second installation cavity, preventing dust and humid air from entering the first installation cavity and the second installation cavity along the gaps and affecting the components. A display and operation buttons are provided on the first door panel or the second door panel. Among them, the display uses a high-brightness OLED display screen, which not only saves power but also can display various parameters such as time, working status, working mode, power, and wireless binding information in real time. The human-machine interface is simple and clear, and the operation buttons can be used to issue manual control commands and adjust various parameters, etc., with simple operation.
[0022] 7. The fixing bolts pass through the connecting holes on the fixing plate and the reinforcing plate and are installed on the ground or wall, thereby realizing the fixation of the box body. The fixing plate and the reinforcing plate can not only increase the structural strength of the box body but also protect the explosion-proof joint. Description of the Drawings
