Description

Technical Field

[0001] This invention relates to the field of electrical equipment accessories, specifically a compact, environmentally friendly gas-insulated switch cabinet. Background Technology

[0002] In the process of power system transformation towards green and intelligent, compact environmentally friendly gas-insulated switchgear is widely used in urban power distribution networks, rail transit, data centers and new energy power plants due to its advantages such as small size, strong environmental adaptability and high insulation reliability. A search revealed that Chinese patent CN219659275U discloses a compact, environmentally friendly gas-insulated switchgear, including a switchgear, a sulfur hexafluoride assembly, a working chamber, and a high-efficiency gas filling and ventilation assembly. The switchgear can be filled and ventilated more safely and efficiently, improving the safety of the switchgear.

[0003] While the above technical solutions solve the problem of gas leak detection and recovery, their sealing performance is poor. The environmentally friendly gas inside the cabinet will not harm the human body, and external dust can easily enter the cabinet through the gaps in the exhaust vents or the sealing gaps of the one-way valve, reducing insulation performance, aggravating component wear, and causing faults such as poor contact and short circuits. In view of the above technical defects, a solution is proposed. Summary of the Invention

A driven shaft is movably connected inside the airflow circulation heat conduction plate. A driven disk is fixedly installed on the surface of the driven shaft. The driven disk is located at the bottom of the active disk. A circulation fan is fixedly installed at the bottom of the driven shaft. The bottom of the heat conduction column is fixedly installed at the top of the airflow circulation heat conduction plate.

[0005] Furthermore, the elastic follow-up cleaning assembly includes a toothed disc, which is fixedly mounted on the surface of a rotating shaft. A circular sleeve is movably connected to the surface of the rotating shaft. The toothed disc is located inside the circular sleeve. A sliding groove is formed on the inner wall of the circular sleeve. A slider is slidably connected inside the sliding groove. A snap-fit ​​toothed plate is fixedly mounted on the surface of the slider. A shape memory alloy spring is fixedly mounted on one side of the snap-fit ​​toothed plate. The side of the shape memory alloy spring away from the snap-fit ​​toothed plate is fixedly mounted on the inner wall of the circular sleeve through a connecting block. A brush plate is fixedly mounted on the surface of the circular sleeve. The bristles of the brush plate are in contact with the surface of the fine-toothed radiator.

[0006] Furthermore, a fan is fixedly installed on the top of the filter housing, and the output end of the fan is connected to the interior of the filter housing. The fan is located in front of the small turbine-type unpowered fan blade.

[0007] Furthermore, an air filter plate is fixedly installed at the bottom rear side of the filter housing via a flexible hinge.

[0008] Furthermore, a baffle is provided on the front side of the air filter plate, and the surface of the baffle is fixedly installed on the inner wall of the filter shell.

[0009] Furthermore, both the output and input ends of the fan are connected to an integrated high-efficiency filter, with the integrated high-efficiency filter at the fan output end located inside the filter housing.

[0010] Furthermore, a soundproof cover is fixedly installed on the top of the filter housing, and the fan is located inside the soundproof cover.

[0011] Furthermore, a dustproof plate is fixedly installed inside the fine-toothed radiator, the dustproof plate is sleeved on the surface of the rotating shaft, and the dustproof plate is located on top of the active disk.

[0012] Furthermore, a filter cover is fixedly installed inside the airflow circulation heat conduction plate, and the circulation fan blades are located inside the filter cover.

[0013] Furthermore, a reinforcing plate is fixedly installed on the surface of the brush plate, and the side of the reinforcing plate away from the brush plate is fixedly installed on the surface of the circular sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the heat generated during the operation of the switch cabinet body is first gathered through the airflow circulation heat conduction plate, and then quickly conducted to the top fine-toothed heat sink through the heat conduction column, accelerating the heat transfer to the airflow circulation heat conduction plate. The temperature difference formed by heat dissipation inside and outside the filter shell drives the small turbine-type unpowered fan blades to rotate, driving the rotating shaft and active disk to rotate. The active disk drives the driven disk and driven shaft below to rotate through magnetic coupling, thereby driving the circulation fan blades to rotate and realize the airflow circulation inside the cabinet, accelerating the heat transfer to the airflow circulation heat conduction plate. The airflow inside the switch cabinet body forms a directional circulation of upward suction and downward discharge under the drive of the circulation fan blades, achieving the goal of not needing additional power to drive the airflow circulation and heat dissipation auxiliary structure, ensuring the stable operation of the components inside the cabinet.

[0015] 2. In this invention, when the surface of the fine-toothed radiator is covered with a lot of dust after prolonged use and the heat dissipation efficiency decreases, the surrounding temperature rises and is conducted to the shape memory alloy spring, causing the shape memory alloy spring to expand due to heat. This, in turn, pushes the snap-fit ​​toothed plate to slide along the slider in the groove, realizing the engagement of the snap-fit ​​toothed plate with the toothed disk on the surface of the rotating shaft. Subsequently, the rotating shaft rotates, causing the toothed disk to rotate synchronously. The engaged snap-fit ​​toothed plate drives the circular sleeve to rotate accordingly, and the brush plate on the surface of the circular sleeve rotates accordingly. The dust is cleaned by the contact between the brush bristles and the surface of the fine-toothed radiator. This achieves the effect of precisely matching the cleaning needs of the fine-toothed radiator without additional power or manual control.

[0016] 3. In this invention, the temperature sensor monitors the internal temperature of the filter housing in real time. When the shape memory alloy spring is heated and unfolded, the temperature sensor is triggered at the same time and starts the fan through the external controller. The fan injects outside air into the filter housing after filtering it through the integrated air inlet and outlet high-efficiency filter. The air pressure generated inside the filter housing pushes the air filter plate to open, and the air drives the dust generated by cleaning to be discharged quickly. The user can also manually start the fan to reverse and extract the air inside the filter housing to accelerate the heat dissipation efficiency of the fine-tooth radiator and achieve the effect of quickly discharging dust.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, the present invention provides a compact environmentally friendly gas-insulated switch cabinet, including a switch cabinet body 1, a fine-toothed radiator 2 fixedly installed on the top of the switch cabinet body 1, a heat-conducting column 3 fixedly installed on the bottom of the fine-toothed radiator 2, the bottom of the heat-conducting column 3 penetrating into the interior of the switch cabinet body 1, a filter shell 4 fixedly installed on the top of the switch cabinet body 1, a cross mounting bracket 5 fixedly installed inside the filter shell 4, a rotating shaft 6 movably connected inside the cross mounting bracket 5, a small turbine-type unpowered fan blade 7 fixedly installed on the top of the rotating shaft 6, an active disk 8 fixedly installed on the bottom of the rotating shaft 6, the active disk 8 being located inside the fine-toothed radiator 2, a temperature sensor 9 fixedly installed on the top of the inner wall of the filter shell 4, and an airflow circulation assembly 10 fixedly installed inside the switch cabinet body 1. The airflow circulation assembly 10 includes an airflow circulation heat conduction plate 101, which is fixedly installed inside the switch cabinet body 1. A driven shaft 102 is movably connected inside the airflow circulation heat conduction plate 101. A driven disk 103 is fixedly installed on the surface of the driven shaft 102. The driven disk 103 is located at the bottom of the active disk 8. A circulation fan blade 104 is fixedly installed at the bottom of the driven shaft 102. The bottom of the heat conduction column 3 is fixedly installed on the top of the airflow circulation heat conduction plate 101.

[0021] Specifically, the fine-toothed radiator 2 is the core heat dissipation component. Its densely distributed toothed structure greatly expands the heat dissipation area, quickly dissipating the heat transferred by the heat-conducting column 3 to the outside, effectively solving the problem of heat accumulation in the main body 1 of the switch cabinet. The heat-conducting column 3 is made of a metal material with a high thermal conductivity. As the core carrier of heat conduction, it runs through the top of the main body 1 of the switch cabinet and firmly connects the airflow circulation heat-conducting plate 101 and the fine-toothed radiator 2, constructing an efficient heat conduction channel between the inside and outside of the cabinet, ensuring smooth and unobstructed heat transfer. The filter shell 4 not only provides a stable installation space for components such as the cross mounting bracket 5, the rotating shaft 6, and the small turbine-type unpowered fan blade 7, but also protects the internal transmission components, preventing external impurities from affecting transmission stability. At the same time, its structure connected to the outside can create a temperature difference environment, providing rotational power for the small turbine-type unpowered fan blade 7. The cross mounting bracket 5 plays a role in accurately positioning and supporting the rotating shaft 6. Through its internal bearing structure, it is movably connected to the rotating shaft 6, reducing the frictional resistance when the rotating shaft 6 rotates, ensuring smooth and stable rotation of the rotating shaft 6. The small turbine-type unpowered fan blade 7 Driven by airflow generated by temperature difference, rotation requires no additional power source, reducing equipment energy consumption and maintenance costs associated with power component failures. The active disk 8 and driven disk 103 are made of strong magnetic material, working together to achieve non-contact magnetic coupling transmission. The active disk 8 rotates with the shaft 6, generating a magnetic force that drives the driven disk 103 to rotate synchronously, avoiding the wear and jamming problems of traditional mechanical transmissions and improving transmission stability and durability. The top cover of the switch cabinet body 1 is made of aluminum alloy, ensuring no impact on the active disk 8 and driven disk 103. The magnetic coupling of 103 has an impact; the airflow circulation heat conduction plate 101 receives the heat emitted by the components in the cabinet and transfers it to the heat conduction column 3. On the other hand, it provides installation support for the driven shaft 102 and the circulation fan blade 104. Its plate structure can also guide the airflow in the cabinet, improve the airflow driving efficiency of the circulation fan blade 104, promote the uniform distribution of heat in the cabinet, and avoid local overheating. The circulation fan blade 104 accelerates the airflow circulation in the cabinet by rotating, so that the heat in each area of ​​the cabinet can be quickly transferred to the airflow circulation heat conduction plate 101, further improving the overall heat dissipation efficiency.

[0022] like Figures 6 to 9As shown, an elastic follow-up cleaning assembly 11 is installed on the surface of the rotating shaft 6. The elastic follow-up cleaning assembly 11 includes a toothed disk 111, which is fixedly installed on the surface of the rotating shaft 6. A circular sleeve 112 is movably connected to the surface of the rotating shaft 6. The toothed disk 111 is located inside the circular sleeve 112. A groove 113 is provided on the inner wall of the circular sleeve 112. A slider 114 is slidably connected inside the groove 113. A snap-fit ​​toothed plate 115 is fixedly installed on the surface of the slider 114. A shape memory alloy spring 116 is fixedly installed on one side of the snap-fit ​​toothed plate 115. The side of the shape memory alloy spring 116 away from the snap-fit ​​toothed plate 115 is fixedly installed on the inner wall of the circular sleeve 112 through a connecting block. A brush plate 117 is fixedly installed on the surface of the circular sleeve 112. The bristles of the brush plate 117 are in contact with the surface of the fine-toothed radiator 2.

[0023] Specifically, the toothed disc 111 is the core power transmission component, fixed to the surface of the rotating shaft 6. Its tooth structure is precisely matched with the snap-fit ​​toothed plate 115, and through meshing, it stably transmits the rotational power of the rotating shaft 6 to the sleeve 112, providing the power basis for the cleaning action. The tooth surface is treated with wear resistance to reduce wear caused by long-term meshing. The sleeve 112 serves as both a mounting carrier and a transmission intermediary. The internal groove 113 provides a stable sliding guide for the slider 114, ensuring smooth engagement and disengagement of the snap-fit ​​toothed plate 115. It also supports components such as the snap-fit ​​toothed plate 115 and the shape memory alloy spring 116. Externally, it is fixedly connected to the brush plate 117 to realize the transmission of power to the cleaning execution end. The slider 114 and the groove 113 constitute a guide and limiting mechanism. The slider 114 is fixed to the surface of the snap-fit ​​toothed plate 115 and embedded in the groove 113, which can limit the movement trajectory of the snap-fit ​​toothed plate 115, preventing it from deviating and failing to mesh precisely with the toothed disc 111, thus ensuring the transmission of power. Dynamic stability; the snap-fit ​​toothed plate 115 is a key connecting component for meshing transmission. One end is connected to the shape memory alloy spring 116, and the other end has a tooth profile adapted to the toothed disk 111. By sliding, it switches between the meshing and disengaging states with the toothed disk 111, thereby controlling the start and stop of the cleaning action; the shape memory alloy spring 116 is the core of the component's trigger drive, with temperature sensing and deformation reset characteristics. Under normal conditions, it is in a contracted state, separating the snap-fit ​​toothed plate 115 from the toothed disk 111. When heated, it precisely unfolds to push and mesh, and automatically resets after the temperature recovers, realizing adaptive control of the cleaning action; the brush plate 117 and brush bristles are the direct cleaning execution components. The brush plate 117 is made of lightweight and high-strength material, which can ensure structural stability during rotation. The brush bristles are made of wear-resistant and non-static flexible material, which can efficiently clean the dust on the surface of the fine-toothed radiator 2, avoid scratching the tooth surface of the fine-toothed radiator 2, and reduce the problem of secondary pollution caused by static electricity adsorption of dust.

[0024] like Figures 4 to 8As shown, a fan 12 is fixedly installed on the top of the filter housing 4. The output end of the fan 12 is connected to the interior of the filter housing 4. The fan 12 is located in front of the small turbine-type non-powered fan blade 7. Both the output end and the input end of the fan 12 are connected to an integrated inlet and outlet high-efficiency filter 15. The integrated inlet and outlet high-efficiency filter 15 at the output end of the fan 12 is located inside the filter housing 4. A soundproof cover 16 is fixedly installed on the top of the filter housing 4. The fan 12 is located inside the soundproof cover 16.

[0025] Specifically, the fan 12 is an active airflow drive component, adopting a low-power, high-pressure design; the integrated inlet and outlet high-efficiency filter 15 is the core component of air purification, connected to the input and output ends of the fan 12 respectively. The input filter is responsible for filtering dust, particulate matter, and other impurities from the air drawn in from the outside. It adopts a replaceable design, which is convenient for later maintenance and cleaning, and ensures long-term stable filtration effect; the soundproof cover 16 is a noise reduction and protection component, adopting a composite structure of sound insulation cotton and metal shell, which completely covers the fan 12. It can effectively absorb the mechanical noise and airflow noise generated by the fan 12 during operation, reducing the impact of noise on the external environment. At the same time, the soundproof cover 16 has certain dustproof and waterproof performance, which can provide additional protection for the fan 12 and extend the service life of the fan 12.

[0026] like Figures 1 to 4 As shown, an air filter plate 13 is fixedly installed on the bottom rear side of the filter housing 4 by a flexible hinge; a baffle 14 is provided on the front side of the air filter plate 13, and the surface of the baffle 14 is fixedly installed on the inner wall of the filter housing 4.

[0027] Specifically, the air filter plate 13 is the core component of the pre-filter, made of a highly breathable filter material. It can efficiently intercept large particulate impurities such as dust and lint in the air, preventing them from entering the filter housing 4 and clogging subsequent components or contaminating the transmission and heat dissipation structures. It is connected to the filter housing 4 via a flexible hinge. The flexible hinge is the opening and closing drive and reset component of the air filter plate 13. It has good elastic deformation and reset performance, which can support the air filter plate 13 to rotate flexibly. At the same time, it can provide a stable pre-tightening force after closing to ensure that the filter plate and the filter housing 4 fit tightly and avoid sealing gaps. It also has corrosion-resistant and wear-resistant properties, which are suitable for long-term opening and closing use. The baffle 14 provides a certain degree of support and protection for the air filter plate 13, preventing the air filter plate 13 from deforming and shaking due to excessive airflow pressure, and ensuring the filtration effect and structural stability.

[0028] like Figures 3 to 7As shown, a dustproof plate 17 is fixedly installed inside the fine-tooth radiator 2. The dustproof plate 17 is sleeved on the surface of the rotating shaft 6 and is located on top of the active disk 8. A filter cover 18 is fixedly installed inside the airflow circulation heat conduction plate 101, and the circulation fan blade 104 is located inside the filter cover 18. A reinforcing plate 19 is fixedly installed on the surface of the brush plate 117, and the side of the reinforcing plate 19 away from the brush plate 117 is fixedly installed on the surface of the circular sleeve 112.

[0029] Specifically, the dustproof plate 17 is made of a thin, wear-resistant, non-magnetic material. It will not interfere with the magnetic coupling transmission of the active disk 8, and it can precisely block dust from entering the transmission core area where the active disk 8 is located, preventing dust from causing transmission jamming or wear. At the same time, its installation method of mounting the rotating shaft 6 does not affect the normal rotation of the shaft 6, ensuring the coordinated operation of the heat dissipation and cleaning systems. The filter cover 18 is an impurity interception component in the airflow circulation area. It is fixed inside the airflow circulation heat conduction plate 101 and covers the circulation fan blades 104. Using a highly breathable filter material, it can efficiently intercept fine dust and impurities carried in the airflow, preventing impurities from adhering to the circulation fan blades 104. 4. Surfaces can affect airflow drive efficiency or enter the airflow circulation heat conduction plate 101 and block the heat conduction channel, ensuring smooth airflow circulation and stable heat dissipation efficiency inside the cabinet; the reinforcing plate 19 is a structural reinforcement component of the brush plate 117, made of high-strength metal material. By fixing the brush plate 117 and the round sleeve 112 at both ends respectively, a stable support structure is formed, which can effectively disperse the reaction force received by the brush plate 117 during rotation and cleaning, and prevent the brush plate 117 from bending or deforming due to long-term stress or high-speed rotation. At the same time, it improves the firmness of the connection between the brush plate 117 and the round sleeve 112, prevents parts from falling off during the cleaning process, and ensures the stability and reliability of the cleaning action.

[0030] The working principle of this invention: The heat generated by the switch cabinet body 1 during operation is collected by the airflow circulation heat conduction plate 101 and transferred to the fine-tooth radiator 2 through the heat conduction column 3 with a high thermal conductivity. The temperature difference formed by heat dissipation inside and outside the filter shell 4 drives the small turbine-type unpowered fan blade 7 to rotate, which in turn drives the rotating shaft 6 and the active disk 8 to rotate. The active disk 8 drives the driven disk 103 and the driven shaft 102 to rotate through magnetic coupling, which in turn drives the circulation fan blade 104 to form a directional airflow circulation of upward suction and downward exhaust in the cabinet, accelerating the conduction of heat to the airflow circulation heat conduction plate 101 to achieve efficient heat dissipation. When dust accumulates on the surface of the fine-tooth radiator 2, causing a decrease in heat dissipation efficiency and an increase in the surrounding temperature, the shape memory alloy spring 116 is heated and unfolds, pushing the locking tooth plate 115 along the slide groove 113 slider 1. 14 slides and meshes with the toothed disc 111. The rotational power of the rotating shaft 6 is transmitted to the brush plate 117 through the toothed disc 111 and the circular sleeve 112, realizing adaptive cleaning of dust on the surface of the fine-toothed radiator 2. The temperature sensor 9 monitors the temperature inside the filter shell 4 in real time. When the shape memory alloy spring 116 unfolds, it triggers the start of the fan 12. Outside air enters the filter shell 4 after being filtered by the integrated inlet and outlet high-efficiency filter 15. The air pressure pushes the air filter plate 13 to open and drive the dust to be cleaned out. Alternatively, the fan 12 can be manually started to reverse and extract the air inside the filter shell 4 to accelerate heat dissipation. After the equipment is started, it can enter the automatic operation state without additional operation. It relies on the non-powered structure to achieve heat dissipation and airflow circulation. During operation, the equipment automatically completes dust accumulation monitoring, adaptive cleaning and auxiliary dust removal and heat dissipation.
