Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically a waterproof smart grid distribution box. Background Technology

[0002] With the continuous advancement of smart grid construction, distribution boxes, as end nodes of the power grid, are being deployed extensively in complex outdoor environments. In order to achieve real-time monitoring of the power grid's operating status, dynamic load regulation, and fault early warning, distribution boxes integrate a large number of sophisticated electronic devices such as smart gateways, data acquisition terminals, communication modules, and control circuits.

[0003] However, the harsh and variable outdoor environment makes rainwater leakage a major cause of short circuits, corrosion failures, and unstable operation of intelligent components inside distribution boxes due to moisture. Traditional outdoor distribution boxes typically employ a sealed enclosure design or have simple louvers on the side walls to maintain internal air convection. However, existing protection technologies have the following significant problems: Existing protection mechanisms mostly rely on fixed protective structures and lack the ability to respond to external climatic conditions (such as rainfall intensity) in real time. Under extreme weather conditions such as rainstorms and typhoons, existing protection measures often fail to achieve proactive protection, causing power equipment to lose physical barrier protection at its most vulnerable moment, which greatly reduces the operational reliability and service life of the power distribution system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a waterproof smart grid distribution box that can automatically reduce or close the first opening on the box during rainfall, and can also automatically open the first opening after the rain stops.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waterproof smart grid distribution box, comprising: The enclosure has a first vent on each of its two sides for heat dissipation. A rainproof mechanism is installed at the first opening to change the size of the heat dissipation channel of the first opening; The weight sensing mechanism is installed on the box body to collect rainwater during rainfall and generate downward displacement based on the weight of the rainwater. The transmission mechanism connects the weight sensing mechanism and the rain protection mechanism; During rainfall, the weight sensing mechanism displaces by catching rainwater and drives the rain-blocking mechanism to reduce or close the heat dissipation channel of the first opening through the transmission mechanism. After the rain stops and the rainwater is discharged, the weight sensing mechanism resets and drives the rain-blocking mechanism to reopen the first opening through the transmission mechanism.

[0006] Furthermore, it also includes a bird-proof mechanism, which is installed on the weight-sensing mechanism to prevent birds from landing on it and causing the weight-sensing mechanism to malfunction.

[0007] Furthermore, the rainproof mechanism includes an adjustment component, several second plates, several first rods, and several first blocks. One second plate, one first rod, and two first blocks form a group. One end of each of the two first blocks is fixedly connected to the inner wall of the housing, and the two first blocks are located on opposite sides of the same first opening. The middle part of the first rod is fixedly connected to one side of the second plate, and both ends of the first rod are rotatably connected to the two first blocks. The second plate is matched and aligned with the first opening. The same end of each of the several first rods is connected to one end of the adjustment component, and the other end of the adjustment component extends through to the outside of the housing and is connected to the transmission mechanism.

[0008] Furthermore, the adjustment assembly includes a rack plate, several gears, and several third rods. One end of each of the several third rods is fixedly connected to one end of each of the several first rods. The other end of each of the several third rods extends through the outside of the housing and is fixedly connected to each of the several gears. One end of the rack plate is connected to the transmission mechanism, and the rack plate meshes with each of the several gears.

[0009] Furthermore, the weight sensing mechanism includes a second box, an arc-shaped plate, a spring, a fourth rod, an annular plate, and a hollow column. A sixth through-hole is provided through the bottom surface of the second box. The lower ends of the spring and the fourth rod are fixedly connected to the upper surface of the outer wall of the box. The upper end of the spring is fixedly connected to the bottom surface of the outer wall of the second box. The upper end of the fourth rod passes through the sixth through-hole into the interior of the second box and is connected to the bird-proof mechanism. The outer peripheral wall of the annular plate is fixedly connected to the inner wall of the second box. The upper surface of the annular plate is fixedly connected to the lower end of the hollow column. The upper end of the hollow column is fixedly connected to the bottom surface of the arc-shaped plate. Several fourth through-holes are provided through the peripheral wall of the upper end of the hollow column. A fifth through-hole is formed between the arc-shaped plate and the inner wall of the upper end of the second box. A grid mesh is provided inside the fifth through-hole. The fifth through-hole, the fourth through-hole, the interior of the second box, and the interior of the sixth through-hole are connected. The sixth through-hole is a circular through-hole. The cross-section of the fourth rod is I-shaped, so that a small gap is formed between the fourth rod and the inner wall of the sixth through-hole for slow drainage.

[0010] Furthermore, a tube is fixedly connected to one side of the upper end of the second box, and a seventh through-hole is opened through one side of the upper end of the second box, with the fifth through-hole, the seventh through-hole, and the inside of the tube connected.

[0011] Furthermore, the transmission mechanism includes an L-shaped plate, a third plate, a second rod, a fifth rod, and a sixth rod. The upper surface of one end of the L-shaped plate abuts against the bottom surface of the outer wall of the second box. The middle part of the L-shaped plate is connected to the box body through the fifth rod. The other end of the L-shaped plate is rotatably connected to one end of the third plate through the sixth rod. The other end of the third plate is fixedly connected to the middle part of the second rod. The two ends of the second rod are respectively fixedly connected to one end of two rack plates.

[0012] Furthermore, a first box body is fixedly connected to the upper surface of the outer wall of the box body. A second opening is provided on the side of the first box body near the box body. An L-shaped plate is located in the second opening, and the middle part of the L-shaped plate is rotatably connected to one end of the first box body through a fifth rod body. The upper and lower sides of the L-shaped plate near the second box are fixedly connected with second flexible protective components. The other ends of the two second flexible protective components are fixedly connected to the upper surface of the outer wall of the box and the top surface of the second opening, respectively. The upper surface of the first box is also provided with a groove, which is located below the tube. The groove is inclined and the end closer to the second box is higher.

[0013] Furthermore, the bird-proof mechanism includes a first plate and several spikes. The bottom surface of the first plate is fixedly connected to one end of the fourth rod located inside the second box. The upper surface of the first plate is fixedly connected to the lower ends of several spikes, and the tips of several spikes penetrate to the outside of the arc-shaped plate.

[0014] Furthermore, a fourth plate is fixedly connected to the bottom surface of the inner wall of the second box, and the upper surface of the fourth plate abuts against the bottom surface of the first plate; Both sides of the outer wall of the box are fixedly connected to the shell. The two adjustment components are located in the two shells respectively. A third opening is opened through the adjacent side of the two shells. The two ends of the second rod pass through the two third openings respectively and are slidably connected to the third openings. Two first flexible protective parts are fixedly connected to the outer wall of the shell near the third opening. The adjacent ends of the two first flexible protective parts are fixedly connected to the outer wall of the second rod. Both the first and second flexible protective components are bellows panels; The outer walls of the box body near the two first openings are fixedly connected to the frame body, and the thickness of the two frame bodies is not less than the width of the folded second plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This type of waterproof smart grid distribution box uses a weight sensing mechanism to collect rainwater as a physical counterweight in the second box during rainfall. This directly transforms the climate change of rainfall into a downward mechanical driving force that triggers rain protection. After the rain stops and the water is drained, the system automatically resets using the elasticity of the spring. The entire process achieves a passive and automatic response technical effect.

[0016] This type of waterproof smart grid distribution box, through the setting of a transmission mechanism, can not only smoothly transmit the displacement generated by the weight sensing mechanism to the rainproof mechanism on both sides of the box, but also effectively amplify the gravity effect generated when the water sinks by using the lever structure formed by the L-shaped plate, which greatly improves the sensitivity and response speed of the system to trigger the closing action in the early stage of rainfall.

[0017] This type of waterproof smart grid distribution box, by setting up a bird-proof mechanism with spikes, physically prevents birds from stopping and landing in the flat area. This avoids the risk of the weight sensor mechanism malfunctioning due to downward displacement caused by the weight of the birds or the long-term accumulation of bird droppings, thus improving the reliability of the equipment in long-term outdoor operation.

[0018] This type of waterproof smart grid distribution box, by setting up a pipe body, a seventh port, and a fourth rod body with an I-shaped cross-section that cooperates with the sixth port, provides a normalized micro-drainage and drainage channel for initial rainfall or a very small amount of water accumulation. This prevents a small amount of water that is insufficient to trigger the system from remaining inside the second box for a long time, and avoids component corrosion or insect breeding caused by water accumulation.

[0019] This type of waterproof smart grid distribution box, by setting up a first box body and a first flexible protective component and a second flexible protective component with an accordion-like structure, achieves semi-enclosed protection and dynamic expansion and contraction sealing for external transmission components. It effectively isolates external rainwater, dust, and fallen leaves from the outside from entering the interior through the movement gaps, ensuring long-term smoothness and maintenance-free operation of the mechanical transmission process.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Please see Figures 1-12 A waterproof smart grid distribution box, comprising: Box 1, with a first vent 12 for heat dissipation on both sides; Rain-proof mechanism 5 is located at the first opening 12 and is used to change the size of the heat dissipation channel of the first opening 12. The weight sensing mechanism 3 is installed on the box 1 and is used to collect rainwater during rainfall and generate downward displacement based on the weight of the rainwater. The transmission mechanism 7 is connected between the weight sensing mechanism 3 and the rainproof mechanism 5; During rainfall, the weight sensing mechanism 3 is displaced by catching rainwater and drives the rain-blocking mechanism 5 to reduce or close the heat dissipation channel of the first opening 12 through the transmission mechanism 7. After the rain stops and the rainwater is discharged, the weight sensing mechanism 3 is reset and drives the rain-blocking mechanism 5 to reopen the first opening 12 through the transmission mechanism 7.

[0024] It also includes a bird-proof mechanism 4, which is installed on the weight sensing mechanism 3 to prevent birds from landing on it and causing the weight sensing mechanism 3 to malfunction.

[0025] Furthermore, in order to ensure the heat dissipation of various components inside the housing 1 during non-rainy weather, and in order to adjust the size of the first opening 12 of the housing 1 or even close it in a timely manner according to the amount of rainfall during rain, as a preferred embodiment of the present invention, the rainproof mechanism 5 includes an adjustment component 54, a plurality of second plates 51, a plurality of first rods 52 and a plurality of first blocks 53, wherein one second plate 51, one first rod 52 and two first blocks 53 form a group, one end of each of the two first blocks 53 is fixedly connected to the inner wall of the housing 1, and the two first blocks 53 are respectively located on both sides of the same first opening 12, the middle part of the first rod 52 is fixedly connected to one side of the second plate 51, and the two ends of the first rod 52 are respectively rotatably connected to the two first blocks 53, the second plate 51 is matched and aligned with the first opening 12, the same end of each of the plurality of first rods 52 is connected to one end of the adjustment component 54, and the other end of the adjustment component 54 extends through to the outside of the housing 1 and is connected to the transmission mechanism 7; Specifically, by setting up a rainproof mechanism 5, multiple rotatable second plates 51 are used to keep them tilted and unfolded under normal circumstances to facilitate air convection and heat dissipation inside the box 1. When it rains, they can be flipped and closed in time to effectively prevent rain from splashing into the box 1 through the first opening 12 under wind pressure, thus ensuring the safe operation of the internal electrical components.

[0026] Furthermore, in order to enable timely rotation of the second plate 51 around the first rod 52 during rainfall to change the size of the first opening 12, as a preferred embodiment of the present invention, the adjustment assembly 54 includes a rack plate 541, a plurality of gears 542 and a plurality of third rods 543. One end of each of the third rods 543 is fixedly connected to one end of each of the first rods 52, and the other end of each of the third rods 543 extends through the outside of the housing 1 and is fixedly connected to each of the gears 542. One end of the rack plate 541 is connected to the transmission mechanism 7, and the rack plate 541 meshes with each of the gears 542. Specifically, by setting the adjustment component 54, the linear stretching motion transmitted from the transmission mechanism 7 is converted into the same-direction rotational motion of the third rod 543 through the meshing of the rack plate 541 and the gear 542, thereby realizing the synchronous flipping of multiple second plates 51 in a purely mechanical and reliable manner.

[0027] Furthermore, in order to detect rainfall in a timely manner and to automatically reset after the rain stops, as a preferred embodiment of the present invention, the weight sensing mechanism 3 includes a second housing 31, an arc-shaped plate 32, a spring 33, a fourth rod 34, an annular plate 35, and a hollow column 36. A sixth opening 313 is provided through the bottom surface of the second housing 31. The lower ends of the spring 33 and the fourth rod 34 are fixedly connected to the upper surface of the outer wall of the housing 1. The upper end of the spring 33 is fixedly connected to the bottom surface of the outer wall of the second housing 31. The upper end of the fourth rod 34 passes through the sixth opening 313 into the interior of the second housing 31 and connects to the bird-proof mechanism 4. The outer peripheral wall of the annular plate 35 is connected to the second housing 31. The inner wall is fixedly connected, the upper surface of the annular plate 35 is fixedly connected to the lower end of the hollow column 36, the upper end of the hollow column 36 is fixedly connected to the bottom surface of the arc plate 32, and a number of fourth openings 301 are opened through the peripheral wall of the upper end of the hollow column 36. A fifth opening 302 is formed between the arc plate 32 and the inner wall of the upper end of the second box 31. A grid is provided inside the fifth opening 302. The fifth opening 302, the fourth opening 301, the interior of the second box 31 and the interior of the sixth opening 313 are connected. The sixth opening 313 is a circular through hole. The cross section of the fourth rod 34 is I-shaped, so that a small gap is formed between the fourth rod 34 and the inner wall of the sixth opening 313 for slow drainage. Specifically, by setting up a weight sensing mechanism 3, rainwater is collected by the second box 31 to increase the counterweight, thereby breaking the original force balance of the spring 33 and causing downward displacement. This directly transforms the external rainfall climate change into a mechanical driving force to trigger the rain protection. After the rain stops and the water is drained, the system automatically resets by relying on the elasticity of the spring 33, achieving the technical effect of passive and intelligent response.

[0028] Furthermore, there may be situations where light rain is insufficient to trigger the operation of the weight sensing mechanism 3, but the weight sensing mechanism 3 still collects a small amount of rainwater. In order to drain this rainwater in a timely manner, as a preferred embodiment of the present invention, a tube 312 is fixedly connected to one side of the upper end of the second box 31, and a seventh opening 314 is provided through one side of the upper end of the second box 31. The fifth opening 302, the seventh opening 314 and the tube 312 are internally connected. Specifically, by setting up the pipe body 312 and the seventh port 314, a regular micro-drainage channel is provided for initial rainfall or a very small amount of water accumulation, preventing a small amount of water that is insufficient to trigger the system to remain inside the second box 31 for a long time, and avoiding component corrosion or mosquito breeding caused by water accumulation.

[0029] Furthermore, in order to promptly apply this power to the closing of the second plate 51 when the weight sensing mechanism 3 receives rainwater and drops due to gravity, as a preferred embodiment of the present invention, the transmission mechanism 7 includes an L-shaped plate 71, a third plate 72, a second rod 73, a fifth rod 74, and a sixth rod 75. The upper surface of one end of the L-shaped plate 71 abuts against the bottom surface of the outer wall of the second box 31. The middle part of the L-shaped plate 71 is connected to the box 1 through the fifth rod 74. The other end of the L-shaped plate 71 is rotatably connected to one end of the third plate 72 through the sixth rod 75. The other end of the third plate 72 is fixedly connected to the middle part of the second rod 73. The two ends of the second rod 73 are respectively fixedly connected to one end of the two rack plates 541. Specifically, by setting up the transmission mechanism 7, not only can the lever structure formed by the L-shaped plate 71 effectively amplify the gravity effect generated when the second box 31 sinks, and improve the sensitivity of rainfall triggering, but also the displacement generated by the weight sensing mechanism 3 can be stably and smoothly distributed to the adjustment components 54 on both sides of the box 1.

[0030] Furthermore, since the transmission mechanism 7 is directly exposed to the environment, it is possible that debris may accumulate on the transmission mechanism 7 due to wind, or that birds may land on it and cause it to be accidentally activated, which may lead to the misadjustment of the size of the first opening 12 during non-rainy periods, thereby affecting the normal heat dissipation of the internal components of the box 1. As a preferred embodiment of the present invention, a first box 2 is fixedly connected to the upper surface of the outer wall of the box 1. A second opening 22 is opened on the side of the first box 2 near the box 1. An L-shaped plate 71 is located in the second opening 22, and the middle part of the L-shaped plate 71 is rotatably connected to one end of the first box 2 through a fifth rod 74. Specifically, by setting up the first box 2, a semi-enclosed structural shelter is provided for the L-shaped plate 71 exposed on the top of the box 1 and its hinge transmission point, which effectively prevents outdoor leaves, flying insects and other debris from getting stuck at the moving joint, ensuring the smoothness and long-term reliability of the lever transmission process.

[0031] Furthermore, since one end of the L-shaped plate 71 is located below the second box 31, and the L-shaped plate 71 is the main component for transmitting kinetic energy, in order to prevent debris from entering the second opening 22 and jamming the L-shaped plate 71, thereby affecting the normal operation of the L-shaped plate 71, as a preferred embodiment of the present invention, the upper and lower sides of the L-shaped plate 71 near the second box 31 are fixedly connected with second flexible protective members 711, and the other ends of the two second flexible protective members 711 are fixedly connected to the upper surface of the outer wall of the box 1 and the top surface of the second opening 22, respectively. Specifically, by setting the second flexible protective component 711, the gap between the L-shaped plate 71 and the second opening 22 when it swings up and down is blocked, further isolating external rainwater and dust from flowing back into the first box 2 or the box 1 through the gap.

[0032] Furthermore, since the pipe 312 will also drain water, in order to facilitate the drainage of the rainwater out of the box 1 and to minimize the impact of this drainage on the L-shaped plate 71, as a preferred embodiment of the present invention, a groove 21 is also provided on the upper surface of the first box 2. The groove 21 is located below the pipe 312, the groove 21 is inclined, and the end closer to the second box 31 is higher. Specifically, by setting up a trough 21, it is specifically designed to receive sporadic rainwater discharged from the pipe 312, and uses its own inclined slope to quickly guide the water flow to the edge of the box 1 to drip down, thus avoiding the discharged water from overflowing, soaking or corroding the transmission components below.

[0033] Furthermore, since the box 1 is located outdoors, in order to prevent birds from landing on the second box 31 and causing the second box 31 to fall when it is not raining, as a preferred embodiment of the present invention, the bird-proof mechanism 4 includes a first plate 42 and a plurality of spikes 41. The bottom surface of the first plate 42 is fixedly connected to one end of the fourth rod 34 located inside the second box 31, and the upper surface of the first plate 42 is fixedly connected to the lower ends of the plurality of spikes 41. The tips of the plurality of spikes 41 all penetrate to the outside of the arc-shaped plate 32. Specifically, by setting up a bird-proof mechanism 4, the spikes 41 exposed above the curved plate 32 physically prevent birds from stopping and landing in the flat area, thus avoiding the situation where the weight sensing mechanism 3 malfunctions due to the weight of the birds or the accumulation of bird droppings.

[0034] Furthermore, since the second box 31 is directly exposed to the environment, although the grid of the fifth opening 302 prevents large debris from falling into the second box 31, there is still a possibility that dust may enter the interior of the second box 31. In order to avoid the accumulation of this dust inside the second box 31 and affect the lifting and lowering of the fourth rod 34, as a preferred embodiment of the present invention, the bottom surface of the inner wall of the second box 31 is fixedly connected to the fourth plate 311, and the upper surface of the fourth plate 311 abuts against the bottom surface of the first plate 42. Specifically, by setting up a fourth plate 311 that is partially raised, the first plate 42 is suspended in the air under normal conditions and does not directly contact the bottom surface of the second box 31, thereby ensuring that even if a small amount of mud and dust settles on the bottom edge of the box, it will not rub, jam or interfere with the normal up and down movement of the first plate 42 and the fourth rod 34.

[0035] Furthermore, since the housing 1 is located in an outdoor environment, in order to avoid the influence of debris in the external environment on the adjustment components 54, as a preferred embodiment of the present invention, housings 6 are fixedly connected to both sides of the outer wall of the housing 1, and the two adjustment components 54 are respectively located in the two housings 6. A third opening 62 is provided through the adjacent side of the two housings 6. The two ends of the second rod 73 are respectively through the two third openings 62 and slidably connected to the third openings 62. Two first flexible protective members 61 are fixedly connected to the outer wall of the housing 6 on the side near the third opening 62. The adjacent ends of the two first flexible protective members 61 are fixedly connected to the outer wall of the second rod 73. Specifically, by setting up the housing 6 and the first flexible protective member 61, the precision gear 542 rack plate 541 is wrapped and isolated. At the same time, the first flexible protective member 61, while allowing the second rod body 73 to slide up and down to transmit force, seals the third opening 62 to prevent rainwater and dust from entering and causing the gear 542 mechanism to jam and rust.

[0036] Furthermore, as a preferred embodiment of the present invention, both the first flexible protective member 61 and the second flexible protective member 711 are bellows panels; Specifically, by setting both the first flexible protective component 61 and the second flexible protective component 711 as bellows panels, the excellent foldable and telescopic characteristics and weather resistance of the bellows panels are utilized to achieve long-term dynamic dustproof and waterproof sealing of the equipment without causing additional mechanical resistance and interference to the movement of each component.

[0037] Furthermore, in order to block the side portions of the second plates 51 and the first opening 12 after the second plates 51 are closed, as a preferred embodiment of the present invention, the outer walls of the box 1 near the two first openings 12 are fixedly connected to the frame 11, and the thickness of the two frame 11 is not less than the width of the second plates 51 after folding. Specifically, by setting the frame 11, when the multiple second plates 51 are completely flipped and closed, the frame 11 can form a physical water-blocking dam on both sides, covering the gap between the edge of the second plate 51 and the side of the first opening 12, eliminating the hidden danger of side leakage and seepage, and greatly improving the overall waterproof level.

[0038] Working principle: When used in non-rainy weather, several second plates 51 are in a normal unfolded state (e.g., tilted at 45 degrees) to ensure that the various components inside the housing 1 can be properly ventilated and dissipated.

[0039] In the early stages of rainfall or during light rain, rainwater will fall directly or along the curved plate 32 into the fifth opening 302. This small amount of rainwater will be discharged directly from the seventh opening 314 and the pipe 312 outside the box. Since the rainfall is small and the duration is short, the triggering conditions are not met, and the adjustment action of the first opening 12 will not be triggered. At this time, maintaining normal ventilation has little impact on the interior of the box 1.

[0040] When there is continuous rainfall or heavy rain, the rainwater in the fifth opening 302 will accumulate and increase. When the water level reaches the overflow height of the fourth opening 301, the rainwater will gradually overflow through the fourth opening 301 and be collected inside the second box 31. As the collected rainwater continues to increase, the weight of the second box 31 will gradually increase, thereby overcoming the elastic force of the spring 33 and moving downward, pressing down on the L-shaped plate 71.

[0041] When one end of the L-shaped plate 71 is pressed, it rotates around the fifth rod 74 as the fulcrum, amplifying the force by utilizing the lever principle. The other end of the L-shaped plate 71 rotates and tilts up, pulling the third plate 72 to move through the sixth rod 75. The displacement of the third plate 72 further drives the second rod 73 to move. Since the second rod 73 passes through the third opening 62 of the housing 6, it is limited to moving vertically. Therefore, the rack plates 541 fixed at both ends of the second rod 73 will also move vertically upwards.

[0042] As the rack plate 541 moves upward, it is driven by the meshing of the gear 542 with the rack plate 541, which drives several gears 542 to rotate synchronously. The rotation of the gears 542 then drives the second plate 51 to flip through the third rod 543, thereby gradually reducing or even closing the heat dissipation channel of the first opening 12, and achieving a physical seal to prevent rainwater backflow.

[0043] During and after rainfall, due to the I-shaped cross-section of the fourth rod 34, there is a small gap between it and the circular sixth opening 313. The water inside the second box 31 will slowly flow out through this gap. When the rainwater inside the second box 31 is basically drained (a very small amount of water below the height of the fourth plate 311 can be dried by natural evaporation), the overall weight of the second box 31 is reduced. Then, under the elastic force of the spring 33, the second box 31 gradually rises and returns to its original position. At this time, the rack plate 541, the second rod 73, and the third plate 72 fall back naturally under their own weight, pulling the L-shaped plate 71 to rotate in the opposite direction, so that the L-shaped plate 71 always keeps against the bottom surface of the second box 31. The various linkage components also complete the reverse movement, pushing the second plate 51 open again, automatically returning to the ventilation and heat dissipation state of a sunny day. The whole process forms a purely mechanical automated cycle, which does not require manual operation. Only cleaning or maintenance of each component is required during regular inspections.
