Description

A high and low voltage distribution cabinet with safety protection function

Technical Field

The invention relates to the technical field of high and low voltage distribution cabinets, and in particular to a high and low voltage distribution cabinet with a safety protection function.

Background Art

As the name implies, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. The low voltage distribution cabinets are then led to the distribution boards, control boxes and switch boxes of various power users. The equipment in the distribution device is a combination of switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices that are assembled into one to meet the design functional requirements.

For example, announcement number CN112103782B discloses a high and low voltage distribution cabinet with a safety protection function. A protection structure is set up to provide safety protection for the wires in the distribution cabinet. When the temperature of the wires is abnormal, the power is cut off through the protection structure inside the distribution cabinet, and the residual current flows into the protection structure, so that the protection structure is in a power-off state, which can prevent the residual current from continuing to flow, thereby avoiding damage to other components and playing a good safety protection role. However, when using high and low voltage distribution cabinets in outdoor environments, due to dust particles in the air, these dusts will enter the ring network box, and the dust can easily adhere to the components. The adhesion of dust will not only interfere with the normal operation of the components and increase the risk of equipment failure, but also weaken its safety protection effect, thereby posing a potential threat to the stability and safety of the entire distribution system.

By means of the above technical solution, the present invention provides a high and low voltage distribution cabinet with safety protection function, which has at least the following beneficial effects:

1. The position adjustment component in the present invention can control the upper and lower positions of the dust blowing and dehumidifying component to ensure that the dust blowing and dehumidifying component can clean at different heights inside the cabinet. No matter where the dust gathers, it can be effectively removed. The dust blowing and dehumidifying component can effectively blow away the dust in the cabinet by generating high-speed airflow, and reduce the humidity inside the cabinet through the dehumidification function, thereby preventing dust from agglomerating due to humidity, further improving the cleaning effect. The introduction of the angle changing component enables the dust blowing and dehumidifying component to adjust its inclination angle as needed, thereby increasing the flexibility of cleaning, solving the problem of dust accumulation in high and low voltage distribution cabinets, and improving the cleaning efficiency and effect.

2. In the present invention, the first drive motor starts to drive the screw to rotate, and the rotational motion of the screw is converted into linear motion of the screw sleeve through the thread. The linear motion of the screw sleeve drives the lifting plate to move up and down, and drives the fixed plate and the dust blowing and dehumidification component to move up and down. In the outdoor high and low voltage distribution cabinet, the position of the dust blowing and dehumidification component can be effectively adjusted to meet the cleaning requirements of different heights in the cabinet.

3. In the present invention, the blowing fan is fixed on the fixing plate. When the blowing fan is started, the generated airflow is transmitted to the connecting pipe through the telescopic hose and blown out by the blowing head. The strong airflow blown out by the blowing head can effectively blow away the dust attached to the components and remove the moisture inside the cabinet.

4. In the present invention, when the second drive motor is started, it drives one of the first gears to rotate forward and reverse continuously. Due to the meshing relationship between the first gear and the second gear, the second gear is driven to rotate synchronously. The rotation of the second gear drives the connecting pipe and the hair dryer head to rotate, thereby changing the blowing direction, so that the hair dryer head can cover a wider area in the cabinet and improve the cleaning efficiency.

5. In the present invention, when the airflow generated by the fan enters the connecting pipe through the telescopic hose, it will first enter the conical contraction part. The conical contraction part can make the airflow gradually contract here, thereby accelerating the flow speed of the airflow. This contraction effect makes the airflow have a higher flow rate and more concentrated energy when it reaches the cylindrical part. Then, the airflow enters the cylindrical part, which is a straight pipe section that can maintain the stability of the airflow. The airflow then enters the conical diffusion part, which makes the airflow gradually spread out to form a wider air outlet surface. In this way, when the airflow finally reaches the exhaust part, it can cover a wider area and achieve a more uniform dust blowing effect. Finally, the airflow is evenly discharged through the multiple exhaust holes of the exhaust part. The design of multiple exhaust holes can ensure that the airflow has a larger coverage when it is blown out, so as to more effectively blow away and remove the dust in the cabinet.

6. In the present invention, when the electric push rod is extended or shortened, it will push or pull the fixed seat, thereby driving the bracket to rotate on the lifting plate, so that the dust blowing and dehumidification component can be flexibly adjusted within a certain angle to meet different cleaning needs.

Working principle: The first drive motor 301 starts to drive the screw rod 302 to rotate, and the rotational motion of the screw rod 302 is converted into the linear motion of the screw sleeve 303 through the thread, and the linear motion of the screw sleeve 303 drives the lifting plate 304 to move up and down, and drives the fixed plate 305 and the dust blowing and dehumidifying component 4 to move up and down;

When the airflow generated by the blowing fan 401 enters the connecting pipe 403 through the telescopic hose 404, it will first enter the conical contraction part 4051. The conical contraction part 4051 can make the airflow gradually contract here, thereby accelerating the flow speed of the airflow. This contraction effect makes the airflow have a higher flow rate and more concentrated energy when it reaches the cylindrical part 4052. Then, the airflow enters the cylindrical part 4052, which is a straight pipe section to maintain the stability of the airflow. The airflow then enters the conical diffusion part 4053, which makes the airflow gradually diffuse to form a wider air outlet surface. In this way, when the airflow finally reaches the exhaust part 4054, it can cover a wider area and achieve a more uniform dust blowing effect. Finally, the airflow is evenly discharged through the multiple exhaust holes 4055 of the exhaust part 4054. The design of the multiple exhaust holes 4055 can ensure that the airflow has a larger coverage when it is blown out. The strong airflow can effectively blow away the dust attached to the components and remove the moisture inside the cabinet;

When the second driving motor 410 is started, it drives one of the first gears 407 to rotate forward and reverse continuously. Due to the meshing relationship between the first gear 407 and the second gear 408, the second gear 408 is driven to rotate synchronously. The rotation of the second gear 408 drives the connecting pipe 403 and the blowing head 405 to rotate, thereby changing the blowing direction, so that the blowing head 405 can cover a wider area in the cabinet 1, thereby improving the cleaning efficiency.

When the electric push rod 501 is extended or shortened, it pushes or pulls the fixing seat 503, thereby driving the bracket 402 to rotate on the lifting plate 304, so that the dust blowing and dehumidifying component 4 can be flexibly adjusted within a certain angle to meet different cleaning needs;

When the exhaust fan 602 is started, negative pressure is generated to exhaust dust or humid air inside the cabinet 1, forming an air circulation.
