Description

Technical Field

[0001] This utility model relates to the field of power distribution room technology, and in particular to a power distribution room louver for heat dissipation and ventilation in winter. Background Technology

[0002] The power plant's power distribution room is the core hub for power distribution and control. It is responsible for receiving external high-voltage power, stepping down the voltage through transformers, and then distributing the power to various production units in the power plant (such as boilers, steam turbines, water pumps, and fans). The room is equipped with high-voltage switchgear, low-voltage distribution cabinets, transformers, busbars, and other equipment. Through relay protection and automatic control devices, it monitors, protects, and dispatches the power system to ensure a stable power supply to power equipment (such as generator sets and compressor sets).

[0003] In daily work, it has been found that existing power distribution rooms mainly rely on air conditioning equipment to maintain a suitable indoor temperature. However, in winter, due to the low outdoor temperature, the outside cold air could be used to assist in cooling and reduce the load on the air conditioning. In reality, because the power distribution room door is often closed (for reasons such as dust prevention, foreign object prevention, and ensuring electrical safety), it is difficult for outside cold air to enter the room. This forces the air conditioning to run at a high load continuously, which increases energy consumption and may also shorten the service life of the equipment due to long-term full-load operation. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology that, in practice, the power distribution room door is often closed (for reasons such as dust prevention, foreign object prevention, and ensuring electrical safety), making it difficult for cold air from the outside to enter the room, which forces the air conditioner to run at a high load continuously, increasing energy consumption. Therefore, this utility model proposes a power distribution room heat dissipation and ventilation louver for winter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a louver for heat dissipation and ventilation in a power distribution room during winter, comprising a door frame, a door, and an auxiliary device, wherein the door is disposed within the door frame and the auxiliary device is disposed on the surface of the door frame. The auxiliary device includes a square hole on the surface of the door frame. A louvered frame is fixedly connected to the inner wall of the square hole. A filter is installed on one side of the louvered frame to intercept and filter dust. A mounting bracket is fixedly connected to the inner wall of the louvered frame. Fan blades are rotatably connected to the inner wall of the mounting bracket. A drive unit is provided on the inner wall of the louvered frame to control the rotation of multiple sets of fan blades to draw cold air from outside into the power distribution room. A cleaning unit is provided on the surface of the louvered frame to clean the dust on the filter. Through the above components, during use, the louvered frame, in conjunction with the square hole, can introduce cold air from outside into the power distribution room in winter. The filter can filter dust, and the drive unit can control the rotation of multiple sets of fan blades to better introduce cold air from outside into the power distribution room. The cleaning unit can clean the dust on the filter.

[0006] Preferably, the drive unit includes a drive motor fixed in the inner wall of the louvered frame, a shaft rotatably connected to the inner wall of the louvered frame, one end of the shaft being fixedly connected to the output end of the drive motor, a plurality of worm gears being fixedly connected to the surface of the shaft, and a plurality of worm wheels being fixedly connected to the surface of the fan blades. The worm gears and worm wheels are meshed together. Through the above components, during use, when the drive motor is turned on, the drive motor drives the worm gears to rotate, and the worm gears, in conjunction with the worm wheels, drive the fan blades to rotate, thereby drawing cold outdoor air into the power distribution room.

[0007] Preferably, the filter section includes a mounting groove formed on the surface of the louvered frame, a filter frame is installed in the mounting groove by screws, and a filter screen is fixedly connected to the inner wall of the filter frame. With the above components, the filter frame can be installed on the inner wall of the mounting groove by screws, and the filter screen can perform dust interception operation.

[0008] Preferably, the cleaning unit includes two sliding grooves formed on the surface of the louvered frame. A cleaning brush is slidably connected to the inner wall of the sliding groove, and a pull rod is fixedly connected to the surface of the cleaning brush. Through the above components, when cleaning is required, the cleaning brush can be moved by the pull rod to realize the cleaning operation.

[0009] Preferably, the pull rod includes a rod body and a threaded rod, the threaded rod being threadedly connected to the inner wall of the rod body. By rotating the threaded rod within the rod body using the aforementioned components, the overall length of the pull rod can be adjusted to facilitate pulling operations.

[0010] Preferably, a ball head is fixedly connected to the lower end of the threaded rod.

[0011] Preferably, the bristles of the cleaning brush are made of nylon.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an auxiliary device, outdoor cold air can be directly introduced in winter through the cooperation of the louvered frame and the square hole. At the same time, the drive unit controls the fan blades to rotate, which can actively draw cold air into the power distribution room, replacing part of the cooling function of the air conditioner. This makes full use of the natural cold source in winter, reduces the operating time and power of the air conditioner, thereby reducing energy consumption and relieving the pressure of long-term high-load operation of the air conditioner.

[0013] In this invention, the filter unit intercepts and filters the introduced cold air through the filter screen inside the filter frame, which can effectively block outdoor dust and debris from entering the power distribution room and reduce the amount of dust adhering to electrical equipment, thus reducing the impact of heat dissipation or causing malfunctions.

[0014] In this invention, a cleaning brush is driven by a pull rod to slide along a groove to clean the dust on the surface of the filter screen, reducing dust accumulation and clogging of the filter screen that would affect ventilation. The pull rod is composed of a rod body and a threaded rod, which can adapt to different operating spaces and allows staff to adjust the grip position according to the actual situation.

A cleaning section 34 is provided on the surface of the louvered frame 32 for cleaning the dust on the filter section 33.

[0019] In this implementation scheme: during use, the louvered frame 32, together with the square hole 31, can introduce cold air from the outside into the power distribution room in winter. The filter part 33 can filter dust, while the drive part 37 can control multiple sets of fan blades 36 to rotate, which can better introduce cold air from the outside into the power distribution room. The cleaning part 34 can clean the dust on the filter part 33.

[0020] Specifically, the drive unit 37 includes a drive motor 372 fixed in the inner wall of the louver frame 32. A shaft 371 is rotatably connected to the inner wall of the louver frame 32.
