[0002] Agricultural equipment refers to the general term for machinery, tools and devices used in agricultural production to complete various stages such as tilling, sowing, fertilizing, irrigating, plant protection, harvesting, transportation and processing. It is an important material foundation for modern agricultural production, aiming to improve agricultural production efficiency, reduce labor intensity, increase the yield and quality of agricultural products, and promote the large-scale, intensive and modern development of agriculture.

[0003] Agricultural equipment used for soil improvement refers to specialized machinery and devices used in agricultural production to improve and optimize the structure, fertility, and physicochemical properties of soil through physical, chemical, or biological means. The core objective of this type of equipment is to create a more suitable soil environment for crop growth, enhance soil productivity, and achieve sustainable agricultural development. However, existing agricultural equipment for soil improvement suffers from uneven distribution of soil conditioners such as lime and fertilizers due to topographical influences. Excessive application in certain areas can burn roots or cause secondary soil salinization. Integrated machines are more suitable for plains and fields, but row spacing matching problems easily arise in hilly terraces and intercropping plots, leading to decreased operational efficiency and high adjustment costs. Some integrated equipment is designed for specific... When planting a different crop, the design requires re-adjusting components, which is time-consuming and labor-intensive. Terrain also affects the uneven distribution of fertilizers and other amendments, leading to localized over-application that burns roots and causes overcrowding. The power grid of a thermal power plant refers to a closed-loop network system within the plant, composed of electrical equipment such as generators, transformers, circuit breakers, disconnectors, busbars, and transmission lines connected by specific electrical connections. Its function is to safely and efficiently transmit the electrical energy generated by the thermal power generating units to the power grid or users through voltage boosting, transmission, and step-down processes, while simultaneously ensuring the stable operation of the power system through monitoring devices and automated control systems.

[0004] The term "power network monitoring and control device for thermal power plants" refers to a general term for various automated devices and systems installed in the power network of thermal power plants to collect and monitor power system operating parameters in real time, and to automatically adjust, control, or protect power equipment according to preset control strategies or system operating requirements. However, in existing power network monitoring and control devices for thermal power plants, the high ambient temperature and dust concentration at the power plant site, insufficient internal heat dissipation space, and the heat-generating components of the processor and power module are prone to overheating due to poor heat dissipation. Long-term overheating accelerates component aging, exacerbates the aging of internal components, and causes short circuits due to dust accumulation on the circuit boards, reducing equipment lifespan, increasing equipment maintenance frequency, and even causing monitoring or control functions to fail due to sudden failures.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A slide rod 302 is fixedly connected to the top right side of the second fixed plate 301, and a movable frame 303 is fixedly connected to the top left side of the second fixed plate 301. Slider blocks 304 are slidably connected to the top of the outer walls of both the movable frame 303 and the slide rod 302. A support block 305 is fixedly connected to the top of the outer wall of the slider 304, and a movable assembly 306 is fixedly connected to the top of the outer wall of the support block 305. Component 306 includes a support frame 3061, which is fixedly connected to the outer wall of the support block 305 on one side. A second motor 3062 is fixedly connected to the left side of the inner wall of the support frame 3061. A roller 3063 is fixedly connected to the output end of the second motor 3062.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The cooling mechanism 4 includes a water storage tank 401, which is fixedly connected to the bottom of the outer wall of the fixed frame 201. A drain pipe 402 is connected to one side of the outer wall of the water storage tank 401. The other end of the drain pipe 402 is fixedly connected to the bottom of the inner wall of the fixed shell 1. A spraying assembly 403 is fixedly connected to the bottom left side of the fixed shell 1. The spraying assembly 403 includes a water sprayer 4031, which is fixedly connected to the bottom left side of the fixed shell 1. An exhaust fan 4032 is fixedly connected to the output end of the water sprayer 4031. Multiple cabinet doors 5 are rotatably connected around the outer wall of the fixed shell 1.

A pulley 7 is rotatably connected to the adjacent side of the outer wall of the multiple fixed feet 8.

[0037] Specifically, when the equipment needs to be cooled, the water in the water storage tank 401 flows into the bottom of the fixed shell 1 through the drain pipe 402. At this time, the water sprayer 4031 is started, which delivers water to the exhaust fan 4032. During the rotation of the exhaust fan 4032, the water is sprayed out in the form of atomization, which creates a cooling effect. The atomized water vapor absorbs the surrounding heat, thereby reducing the internal temperature of the equipment. The cabinet door 5 can be opened or closed as needed. The lock hole 6 is used to lock the cabinet door 5 to ensure safety. The fixed feet 8 support the entire equipment, and the pulleys 7 facilitate the movement and positioning of the equipment, making it convenient to use in different scenarios.

[0038] Working Principle: The heat dissipation mechanism 2 achieves efficient heat dissipation through the coordinated work of multiple components. The temperature gauge 205 is fixed to the bottom of the outer wall of the rotating frame 204. When heat is generated inside the device due to the operation of the power network, the temperature gauge 205 monitors the internal temperature in real time. Once the temperature exceeds the preset threshold, it transmits a signal to the control button 9. After the operator receives the information, the motor 2062, as the power source, starts to run after the power is turned on, driving the blower 2061 to work. The blower 2061 draws in the hot air inside the device and discharges it through the exhaust pipe 2063. Inside the exhaust pipe 2063, the heat dissipation plate 2064 further increases the contact area between the hot air and the outside, accelerating the dissipation of heat and improving the heat dissipation efficiency. The fixed frame 201... The atomizer 2065 on the rear side also participates in the heat dissipation process. The atomizer 2065 atomizes the liquid into tiny particles, which reduce the air temperature through evaporation and heat absorption, thereby helping to reduce the internal temperature of the device. The exhaust port 203 on the top of the fixed plate 202 cooperates with the exhaust assembly 206 to form an air circulation channel. Cold air from the outside can enter the device through the exhaust port 203 to replenish the air gap caused by the hot air discharged by the exhaust assembly 206, promote the circulation of air inside the device, and further enhance the heat dissipation effect. The rotating frame 204 can drive the temperature instrument 205 to rotate, so that the temperature instrument 205 can monitor the temperature at different locations inside the device, ensuring a comprehensive understanding of the overall temperature situation and providing data support for precise heat dissipation.

[0039] When cleaning of the equipment's interior is required, motor 3062 starts, driving roller 3063 to rotate. Since roller 3063 is slidably connected to the top of the outer wall of the moving frame 303, the rotation of roller 3063 causes the entire moving assembly 306 to move linearly along the moving frame 303 and slide bar 302. Slider 304 slides on slide bar 302 and moving frame 303, providing stable support and guidance for moving assembly 306. As moving assembly 306 moves, exhaust plate 3064 and cleaning plate 3065 also move accordingly. During rotation, exhaust plate 3064 can accelerate airflow, blowing up dust and impurities for easy cleaning, while cleaning plate 3065 directly contacts the surface to be cleaned, removing dust and stains, thus achieving the cleaning function of the equipment's interior. The entire cleaning mechanism 3 is powered by motor 3062, utilizing the rolling of roller 3063 and the sliding of slider 304 to achieve linear movement of the cleaning assembly, ensuring efficient cleaning.
