Description

Technical Field

[0001] The invention relates to the field of household daily necessities, and in particular to a prefabricated cabin device based on transformer substation transformation. Background Art

[0002] In the rapidly developing power system, substations serve as a bridge between power generation and power consumption. The stability and reliability of their operation are directly related to the overall safety of the power grid. With the continuous expansion of the power grid and the continuous advancement of power technology, the design and operation mode of traditional substations can no longer meet the needs of modern power grids. Therefore, the transformation and upgrading of substations has become an important issue in the power industry. As an important innovative achievement in substation reconstruction, prefabricated cabin equipment has greatly improved the construction efficiency and operation and maintenance convenience of substations with its integrated and modular characteristics. This type of equipment not only saves land resources but also simplifies the connection and debugging process between equipment by encapsulating various power equipment in prefabricated cabins. However, while improving integration and modularization, prefabricated cabin equipment also faces more severe challenges such as heat dissipation, dust prevention, and moisture resistance. In terms of dust prevention, existing prefabricated cabin equipment mostly relies on filter materials such as filter cotton or filter mesh for air filtration to prevent dust from entering the interior of the equipment; however, this filtering method has many limitations; on the one hand, filter cotton and filter mesh are easy to clog and need to be replaced or cleaned regularly, which increases maintenance costs; on the other hand, when encountering extreme weather such as sandstorms and haze, the filtering effect will be greatly reduced and it is impossible to completely prevent the invasion of dust.

[0003] Therefore, it is necessary to provide a new prefabricated cabin equipment based on substation transformation to solve the above technical problems. Summary of the invention

[0011] Preferably, the outer walls of the active roller and the driven roller are both designed to be made of cloth to increase the friction between the active roller and the filter screen.

[0012] Compared with the related art, the prefabricated cabin equipment based on substation transformation provided by the present invention has the following beneficial effects: Efficient heat dissipation and preliminary filtration: The heat dissipation air is first filtered through a carefully designed filter, which effectively blocks dust, impurities and other particles in the external environment, ensuring that the air entering the prefabricated cabin is cleaner; this step not only improves the air quality, but also reduces the problem of poor heat dissipation of equipment caused by dust accumulation, and improves the heat dissipation efficiency; Intelligent air circulation and deep purification: Through the rotation of the follower blades, the air that has been initially filtered is introduced into a more complex air treatment system; the linkage mechanism between the follower blades and the active bevel gear, the driven bevel gear, the transmission rod and the active pulley realizes efficient energy transmission and conversion; in this process, the air not only drives the rotation of the follower blades, but also drives the operation of the entire transmission system, allowing the air to further enter the U-shaped channel; in the U-shaped channel, the air is fully in contact with the water, and the large specific heat capacity and high heat conduction efficiency of water are used to effectively reduce the air temperature, and the air is further purified through the washing effect of water; in particular, the design of the trapezoidal block allows the air to form a certain water level difference in the channel, which enhances the air cleaning effect and ensures the quality of the air that finally enters the prefabricated cabin; Efficient dehumidification and drying: Although the air after washing in the U-shaped channel is cleaner, it may contain more moisture. At this time, the air is further treated by a moisture-absorbing cloth, which can effectively absorb moisture in the air and convert wet air into dry air. This step not only improves the quality of the air, but also avoids the potential harm of wet air to the electronic equipment in the prefabricated cabin, such as corrosion and short circuit. In addition, the setting of the dryer ensures that the moisture-absorbing cloth can remain dry continuously, realizing recycling and reducing maintenance costs. Environmental protection, energy saving and intelligent management: The design of the entire system fully considers the needs of environmental protection and energy saving. Through efficient air circulation and purification mechanisms, energy consumption and pollution emissions are reduced. At the same time, the intelligent transmission and control mechanism makes the system operation more stable and reliable, reduces the need for manual intervention, and improves operation and maintenance efficiency.

[0021] The working principle of the prefabricated cabin equipment based on substation transformation provided by the present invention is as follows: Preliminary filtration and introduction of air: When the temperature inside the prefabricated cabin body 1 rises and needs to be dissipated, the outside air first enters through the through hole 2 opened on one side of the prefabricated cabin body 1. Before entering the through hole 2, the air will first pass through the filter 7 installed inside the air inlet 5 for preliminary filtration to block dust, impurities and other particles in the external environment, ensuring that the air entering the cabin has a certain degree of cleanliness.

[0022] Air kinetic energy conversion and transmission: The air that has been initially filtered enters the frame 4, and its flow drives the follower blade 10 to start rotating. The rotation of the follower blade 10 drives the driving bevel gear 11 to rotate through the main shaft. The driving bevel gear 11 is meshed and connected with the driven bevel gear 13, thereby transmitting the rotational force to the driven bevel gear 13, and driving the transmission rod 12 and the driving pulley 14 connected thereto to rotate synchronously. In this process, the kinetic energy of the air is effectively converted into mechanical energy, providing power for subsequent air processing.

[0023] Air-water washing purification: With the operation of the transmission system, the air is guided into the U-shaped channel 6. In the U-shaped channel 6, clean water is used as a cooling and purification medium and is in full contact with the air. The air drives the clean water to move during the flow, causing the water level at the other end of the U-shaped channel 6 to gradually rise. Due to the design of the trapezoidal block 9, the outlet in the U-shaped channel 6 gradually increases as the water level rises. This design not only slows down the air flow rate, but also increases the contact time between air and water, thereby improving the air purification effect. After the air is washed with clean water, its temperature is effectively reduced, and impurities and particles therein are further removed.

[0024] Air dehumidification and drying: The air after water washing and purification contains a high amount of moisture and needs to be further processed to avoid adverse effects on the equipment in the prefabricated cabin. At this time, when the air passes through the moisture-absorbing cloth 8, the moisture-absorbing cloth 8 can effectively absorb the moisture in the air and convert it into dry air. This step ensures that the air entering the prefabricated cabin body 1 is dry and clean.

[0025] Air circulation and exhaust: Finally, the purified and dehumidified air enters the prefabricated cabin body 1 and exchanges heat with the high-temperature air in the cabin to achieve a heat dissipation effect. At the same time, the hot air in the cabin is discharged out of the cabin through the action of the exhaust fan blades 3, forming a complete air circulation system. During this process, the dryer 16 works continuously to ensure that the moisture-absorbing cloth 8 remains dry so as to continue the dehumidification process.
