Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a wall-mounted distribution box with moisture-proof effect. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system, and is used in places where the load is relatively dispersed and there are fewer circuits. The motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. A large number of electrical components such as air switches are installed inside the power distribution cabinet. Some of these electrical components are exposed to the air and directly contact the air. Therefore, when using the power distribution cabinet, the power distribution cabinet is required to be kept relatively dry. When the humidity in the power distribution cabinet is too high, it will not only accelerate the damage speed of the electrical components, but also may cause air breakdown and cause safety accidents. Transmission distribution boxes are usually susceptible to external humid environments, which can cause internal equipment to become damp, resulting in malfunctions, which can damage the equipment or cause it to malfunction. Moisture can cause oxidation and corrosion of metal parts, reducing their service life and performance. Traditional distribution box ventilation systems rely on manual operation and lack real-time monitoring and automatic adjustment functions. If the problems of excessive humidity and insufficient ventilation in the distribution box are not solved in a timely manner, the safety, reliability and economic benefits of the equipment will be seriously affected.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The ventilation holes are arranged on both sides of the distribution box body, which are responsible for the inlet and outlet of air. The baffles are matched with the size of the ventilation holes and are usually in a closed state to prevent the external humid air from directly entering the distribution box. When ventilation is needed, the driving motor drives the driving wheel through the output end to drive the operation of the entire transmission system. The power of the driving motor is transmitted to the rotating rod through the driving wheel to rotate it. The rotating rod is equipped with a second synchronous wheel, which is connected to the first synchronous wheel through a synchronous belt, thereby synchronously transmitting the baffle. When the driving motor is started, the rotation of the driving wheel drives the rotating rod to move, and then through the cooperation of the first synchronous wheel and the second synchronous wheel, the meshing between the transmission rack and the transmission wheel causes the baffle to move relative to the ventilation hole. In this way, the baffle can be opened to allow air to flow into or out of the distribution box to form effective ventilation. The driving motor is electrically connected to the external power supply and the single-chip microcomputer to ensure that it can be controlled by the single-chip microcomputer. The single-chip microcomputer can monitor the humidity in the distribution box and automatically control the opening and closing of the driving motor, thereby adjusting the ventilation state as needed; 2. The moisture-proof cotton blanket is set on both sides of the mounting frame, close to the ventilation holes, and has a moisture-absorbing function. It is designed to be detachable for easy regular replacement. The moisture-proof cotton can absorb moisture from the incoming humid air during ventilation, thereby further reducing the humidity inside the distribution box; 3. When the cabinet door is closed, its surface contacts the knocking block, generating a knocking action. This knocking causes the fixed rod to move downward, thereby pushing the reset spring to compress. As the fixed rod moves downward, the top plate inside the transmission slot also moves accordingly. The top plate maintains a stable movement path under the guidance of the guide rod. The eccentric wheel on the movable shaft rotates as the top plate moves. Due to the design of the eccentric wheel, the movement of the top plate causes the rotation of the eccentric wheel. When the eccentric wheel rotates, it pushes the trigger block to move downward. The trigger block cooperates with the touch switch, and the touch switch is triggered, and the trigger The touch switch controls the start or stop of the ventilation fan. The touch switch is connected to the ventilation fan through a connecting harness. When the trigger block activates the touch switch, the ventilation fan will start working to achieve air circulation and ventilation functions. When the cabinet door is opened and the knock block is released, the reset spring will act on the fixed rod to push it back to the initial position, stop the movement of the top plate, and then reset the trigger block and no longer activate the touch switch, effectively realizing the linkage control of the cabinet door switch and the ventilation fan, improving the automation level of the equipment and the convenience of the user, and ensuring the reliability and sensitivity of the system.
