[0036] Please refer to Figure 1 and Figure 2 A photovoltaic tea garden electric control integrated cabinet in a preferred embodiment of the present invention includes a base 100, a cabinet body 200, and a movable frame 300.

[0037] The bottom of the cabinet 200 is fixed to the base 100 , and a mounting cavity 210 is provided in the cabinet 200 . The top and bottom of the mounting cavity 210 are opened.

[0038] The movable frame 300 is movably mounted in the mounting cavity 210 by lifting and lowering, and a cover 310 located above the mounting cavity 210 is connected to the top of the movable frame 300, and a first air port 320 is arranged around the top of the movable frame 300; the movable frame 300 has a ventilation state and a closed state; in the ventilation state, the top opening of the mounting cavity 210 is in an open state, the top edge of the first air port 320 is higher than the top of the side wall of the mounting cavity 210, and the bottom opening of the mounting cavity 210 is in an open state to allow gas to circulate; in the ventilation state, the top edge of the first air port 320 is higher than the top of the side wall of the mounting cavity 210 so that the first air port 320 can ventilate, and of course, the flow area opened by the first air port 320 can be adjusted by lifting and lowering to achieve heat dissipation flow adjustment. In the closed state, the cover 310 closes the upper opening of the installation cavity 210 and the first air outlet 320 is closed by the side wall of the installation cavity 210, and the bottom opening of the installation cavity 210 is closed, so that the installation cavity 210 is in a closed state, reducing the entry of external dust and insects, reducing failures, increasing service life, and reducing maintenance frequency. It is understandable that the side wall of the installation cavity 210 can be provided with a lifting drive mechanism 250 to drive the movable frame 300 to rise and fall, and the lifting drive mechanism 250 can be a telescopic motor, and the number of lifting drive mechanisms can also be set to multiple to achieve multi-position jacking.

[0039] The present invention provides a photovoltaic tea garden electric control integrated cabinet, and the lifting and lowering movement of the movable frame 300 enables the electric control integrated cabinet to be flexibly switched between a ventilation state and a closed state. In the ventilation state, the top edge of the first air port 320 is higher than the top of the side wall of the installation cavity 210, and the bottom opening is in an open state, so that the gas can flow freely, which effectively improves the heat dissipation efficiency. In the closed state, the cover 310 closes the upper opening of the installation cavity 210, the first air port 320 is closed by the side wall of the installation cavity 210, and the bottom opening is closed, so as to achieve sealing protection inside the equipment and prevent dust and insects from entering. Through the lifting and lowering movement of the movable frame 300, dynamic adjustment of the heat dissipation path is achieved. In a high temperature environment, the equipment can be switched to a ventilation state, and efficient gas circulation is achieved through the first air port 320 and the bottom opening to avoid overheating of the equipment. This design significantly optimizes the heat dissipation performance, reduces equipment failures caused by high temperature, and improves the stability and service life of the equipment.

[0040] Reference Figure 3 , Figure 4 and Figure 5In some embodiments of the present invention, a guide extension plate 311 tilted outward and downward is provided at the top edge of the cover 310, and an air passage 312 connected to the first air port 320 is formed between the guide extension plate 311 and the outer side wall of the top of the cabinet 200. A brush shaft 340 is installed in the air passage 312 or at the inlet and outlet of the air passage 312. Specifically, in order to have a larger operating space and facilitate installation, the brush shaft 340 is installed at the inlet and outlet of the air passage 312. The brush shaft 340 is provided with bristles 341, and the bristles 341 are arranged in the circumferential direction and the axial direction. The guide extension plate 311 and the air passage 312 at the top edge of the cover 310 further optimize the gas flow path, and the guide extension plate 311 tilted outward and downward guides the gas to enter and exit the installation cavity 210 more smoothly. The bristles 341 can not only effectively filter the air entering the device, but also reduce the entry of mosquitoes into the installation cavity 210, and reduce the damage of internal electronic components caused by the residual bodies of mosquitoes inside. For easy installation, the brush shaft 340 and the bristles 341 are usually detachable. A sleeve that can rotate synchronously with the brush shaft 340 is provided on the brush shaft 340. Usually, a strip groove can be provided on the brush shaft 340, and a strip protrusion embedded in the strip groove is provided on the inner wall of the brush tube to achieve synchronous rotation. The bristles 341 are connected to the sleeve, so that the brush shaft 340 can be pulled out first when disassembling.

[0041] Reference Figures 2 to 5 In some embodiments of the present invention, one end of the brush shaft 340 passes through the cover 310 and is provided with a first transmission wheel 350. A vertical rack 230 is installed on the cabinet 200, and the first transmission wheel 350 is meshed with the vertical rack 230, so that during the lifting process of the movable frame 300, the first transmission wheel 350 and the brush shaft 340 can rotate and move; the cover 310 is installed with a brush bar 360. For the convenience of installation, a vertical plate extending downward is provided at the outer end of the guide extension plate 311. The brush bar 360 is fixedly installed on the vertical plate, and can be detachably connected to the vertical plate through fasteners, so as to facilitate disassembly and cleaning. The brush bar 360 is provided with brush teeth 361 embedded in the bristles 341, and the brush teeth 361 are arranged along the axial direction of the brush shaft 340. The bristles 341 rotate and enter between the two brush teeth 361, so that the brush teeth 361 scrape off the impurities adhered to the bristles 341. The brush teeth 361 are used to scrape off the impurities adhered to the bristles 341. The meshing design of the first transmission wheel 350 of the brush shaft 340 and the vertical rack 230 enables the brush shaft 340 to automatically rotate during the lifting and lowering of the movable frame 300, and the brush shaft 340 drives the bristles 341 to rotate through the brush teeth 361, thereby scraping off impurities adhering to the bristles, reducing the accumulation of dust or mosquitoes, avoiding affecting the smooth circulation of gas, and preventing accumulated dust and mosquitoes from entering the installation cavity 210, thereby realizing the dynamic cleaning function of the bristles 341, ensuring the smooth flow of the air channel, and improving the long-term operation stability of the equipment.

[0042] Reference Figure 4 and Figure 5In a specific embodiment of the present invention, the first air inlet 320 is arranged on the left and right sides of the top of the movable frame 300; the guide extension plate 311 is arranged on the left and right sides of the cover 310; the brush shaft 340 is arranged symmetrically and located on the left and right sides of the cabinet 200; the front and rear sides of the cover 310 are provided with side baffles 313, and the side baffles 313 in the ventilation state and the closed state both cover the front and rear sides of the cabinet 200. The front and rear ends of the brush shaft 340 are rotatably mounted on the side baffles 313, and the side baffles 313 are provided with a rotation hole for inserting the brush shaft 340. The rotation hole can be installed with a bearing to be mounted on the journal of the brush shaft 340, thereby reducing the rotation friction. The rear end of the brush shaft 340 extends out of the rear side baffle 313, and the first transmission wheel 350 is installed on the rear end of the brush shaft 340. The first transmission wheel 350 and the brush shaft 340 can realize torque transmission through a key, thereby realizing synchronous rotation of the first transmission wheel 350 and the brush shaft 340, and a limit nut can be installed at the rear end of the brush shaft 340 to limit the axial position of the first transmission wheel 350. The left-right symmetric arrangement of the first air port 320 and the guide extension plate 311, combined with the left-right symmetric layout of the brush shaft 340, enables the device to achieve efficient gas circulation and impurity filtration on both sides.

[0043] Reference Figure 2 and Figure 3 In a further embodiment of the present invention, a convex tooth 351 for embedding into the tooth groove of the vertical rack 230 is rotatably installed on the outer periphery of the first transmission wheel 350. A supporting block 352 is provided on the peripheral wall of the first transmission wheel 350 on one side of the convex tooth 351 for the corresponding side of the convex tooth 351 to abut. An elastic member 370 is installed between the convex tooth 351 and the first transmission wheel 350 to push the convex tooth 351 to abut against the supporting block 352; the convex tooth 351 and the supporting block 352 are arranged in a surrounding manner. The one-way transmission of the first transmission wheel 350 and the vertical rack 230 is achieved by the rotation of the supporting block 352, the elastic member 370 and the convex tooth 351, so that the lifting and lowering movement of the movable frame 300 will not drive the reciprocating rotation of the first transmission wheel 350, so that the bristles 341 can rotate repeatedly to easily throw impurities into the installation cavity 210. Figure 8 As shown, when the protruding tooth 351 abuts against the abutting block 352, the protruding tooth 351 can only rotate in one direction, so that when the first transmission wheel 350 rises with the movable frame 300, the first transmission wheel 350 can rotate clockwise, and the bristles 341 will be scraped by the brush teeth 361 at the upper position before entering the bottom of the air passage 312, and the bristles will not drive impurities to be thrown upward into the air passage 312 or even the installation cavity 210.

[0044] Reference Figure 1 and Figure 6In some embodiments of the present invention, the bottom of the cabinet 200 is connected and fixed to the base 100 by the supporting feet 400, so that a second air port 220 is formed between the bottom of the cabinet 200 and the base 100; the bottom of the movable frame 300 is connected to a switching member 330; a transition channel 331 is provided in the switching member 330; the top of the transition channel 331 is connected to the installation cavity 210, and an opening is provided at the bottom; in the ventilation state, the bottom of the switching member 330 is higher than the second air port 220; so that gas can enter the installation cavity 210 through the second air port 220 and the opening at the bottom of the transition channel 331. In the closed state, the bottom of the switching member 330 abuts against the base 100, and the opening at the bottom of the transition channel 331 is closed by the base 100, thereby realizing the closing of the opening of the lower end installation cavity 210. The second air port 220 between the bottom of the cabinet 200 and the base 100, combined with the switching member 330 at the bottom of the movable frame 300, realizes the gas flow control at the bottom of the device. Not only the heat dissipation path is optimized, but also the bottom opening can be flexibly closed by the lifting and lowering of the switching member 330. The opening and closing of the bottom opening are both realized by the lifting and lowering of the movable frame 300, that is, the lifting and lowering of the movable frame 300 can realize the dual control of the opening and closing of the upper first air vent 320 and the closing of the bottom opening of the installation cavity 210, and there is no need to set up two systems to realize the opening and closing of the upper and lower air vent structures.

[0045] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, a filter screen 332 is provided in the transition channel 331. The filter screen 332 in the transition channel 331 further optimizes the air filtering effect. The filter screen 332 can effectively prevent dust and other impurities from entering the interior of the device, thereby improving the protection level of the device and reducing the risk of poor heat dissipation and device damage caused by dust accumulation.

[0046] Reference Figure 7 In a further embodiment of the present invention, a sealing groove 110 is provided at the upper end of the base 100 for the bottom of the closed switching member 330 to be embedded. The sealing groove 110 on the base 100 provides a stable sealing position for the switching member 330, which not only improves the sealing performance of the device in a closed state.

[0047] Reference Figure 7In a further embodiment of the present invention, the outer peripheral wall contour of the switching member 330 is adapted to the bottom opening contour of the installation cavity 210, thereby reducing the installation gap and reducing the dust and impurities from entering from the gap between the peripheral wall of the switching member 330 and the side wall of the bottom opening of the installation cavity 210. Of course, a sealing ring can also be installed between the outer peripheral wall of the switching member 330 and the side wall of the bottom opening of the installation cavity 210. Specifically, the bottom opening contour of the installation cavity 210 is smaller than the contour of the installation cavity 210, so that the bottom of the installation cavity 210 has a partial bottom wall to support the movable frame 300 in a closed state, avoiding that all gravity is concentrated on the switching member 330, resulting in stress concentration at the connection between the movable frame 300 and the switching member 330. A connecting strip 380 is provided at the bottom of the movable frame 300, and corresponding holes are provided on the top of the connecting strip 380 and the switching member 330 to be connected and fixed by fasteners. The movable frame 300 includes a horizontal bar and a vertical bar, and the horizontal bar and the vertical bar form a frame structure, so that the movable frame 300 does not affect the viewing and maintenance of the internal devices when the cabinet door is opened. The movable frame 300 may also be formed by splicing a plurality of frames.

[0048] In some embodiments of the present invention, the cover 310 is provided with a downwardly arched guide arch 314 corresponding to the installation cavity 210. The design of the guide arch 314 on the cover 310 further optimizes the air flow path. The guide arch 314 can effectively guide the air flow, reduce the air retention on the surface of the cover 310, and improve the heat dissipation efficiency of the device.

[0049] It is understandable that, in order to achieve active heat dissipation, a fan 240 may be further disposed in the installation cavity 210 .

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
