[0002] Thermal power plants are the most commonly used power production plants. Electricity is the main energy source for industry, so power plants are called the heart of industry. Power plants must operate continuously without interruption in production, so their control cabinets require higher stability. Control cabinets often use fans to provide heat dissipation to maintain the stability of the control cabinet.

[0003] For example, the patent with the publication number CN210183784U discloses an exhaust fan structure for heat dissipation of the control cabinet of a thermal power plant, including a control cabinet body, cabinet contacts and a pull connecting rod; a group of the exhaust fans are plugged into the control cabinet body; a group of the upper clamping blocks are slidably connected above the mounting hole of the control cabinet body; a group of the side clamping blocks are swingably connected on both sides of the mounting hole of the control cabinet body through two groups of swing connecting rods connected by hinges; the top of the pull connecting rod is hinged with the upper clamping block. The device supplies power to the exhaust fan through the cabinet contacts and the fan contacts. The exhaust fan can be directly disassembled and installed during use without wiring the line or stopping the machine, and the installation safety is higher. At the same time, the device adopts a crank slider mechanism and a double rocker mechanism, and the upper clamping block and the side clamping block can be simultaneously contracted by operating the upper clamping block during use. The exhaust fan is simple and quick to disassemble and install, and the operation is convenient.

[0004] When the existing exhaust fan structure for heat dissipation of the control cabinet of a thermal power plant is in use, a large amount of dust will adhere to the outer wall of the protective cover when the exhaust fan is working, resulting in a decrease in the heat dissipation efficiency of the exhaust fan. In view of this, we propose an exhaust fan structure for heat dissipation of the control cabinet of a thermal power plant. Utility Model Content

[0005] The purpose of the utility model is to provide an exhaust fan structure for heat dissipation of a control cabinet in a thermal power plant in order to solve the problem in the background technology that a large amount of dust may adhere to the outer wall of the protective cover of the exhaust fan.

[0006] In view of this, the utility model provides an exhaust fan structure for heat dissipation of a control cabinet in a thermal power plant, comprising a cabinet body, a mounting frame being installed on the outer wall of the cabinet body, an exhaust frame being arranged inside the mounting frame, an exhaust fan body being installed inside the exhaust frame, a protective cover being fixedly connected to the outer wall of the protective cover, a cleaning frame being fixedly connected to the inner wall of the cleaning frame, a spring being fixedly connected to one end of the spring being fixedly connected to a fitting disk, a rotating plate being fitted to the outer wall of the fitting disk and being screwed to the outer wall of the cleaning frame, a cleaning brush being screwed to the outer wall of the protective cover being fixedly connected to the outer wall of the rotating plate, a knob being fixedly connected to the outer wall of the fitting disk and being penetrated inside the rotating plate, a clamping strip being fixedly connected to the outer wall of the knob, and a clamping disk being clamped to the outer wall of the clamping strip and being fixedly connected to the outer wall of the rotating plate;

[0007] The mounting assembly is located on the inner wall of the exhaust frame and is used to mount the exhaust frame on the outer wall of the mounting frame.

[0008] Based on the above structure, the staff presses the knob, and the movement of the knob drives the clamping strip and the chuck on the outer wall of the rotating plate to engage with each other. Then, the staff turns the knob, and the rotation of the knob drives the cleaning brush on the outer wall of the rotating plate to slide along the outer wall of the protective cover through the engagement operation of the clamping strip and the chuck, so as to clean the dust on the outer wall of the protective cover. After the dust on the protective cover is cleaned, the knob is released to make the clamping strip and the chuck move away from each other.
