Description

Technical Field

[0001] This invention relates to the field of meter box technology, specifically to a waterproof meter box for outdoor use. Background Technology

[0002] A meter box is a specialized enclosure in a power system used to install electricity meters and related electrical components. Its core function is to provide reliable protection for meters, wires, and other electrical equipment, resisting external environmental interference such as wind, rain, dust, and collisions. At the same time, it ensures safe electricity use by implementing standardized circuit wiring through a reasonable layout. Common materials for the outer shell of the box include corrosion-resistant plastics and high-strength metals. The interior is equipped with mounting brackets, terminals, and other components for fixing the meter and connecting the circuit, respectively. This equipment is widely applicable to various electricity use scenarios such as residential buildings, commercial buildings, and industrial plants, adapting to different electricity use environments and ensuring accurate electricity metering and safe circuit operation. Outdoor meter boxes are power equipment protection devices specifically designed for outdoor environments.

[0003] Outdoor meter boxes typically have ventilation holes on their surface to dissipate heat from the inside. However, heavy rain can cause water to seep directly through these holes into the cabinet, near the meter area. Therefore, we have proposed a waterproof meter box for outdoor use. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an outdoor waterproof meter box, including a main cabinet, side cabinets fixedly connected to both sides of the main cabinet, a heat dissipation square hole opened on the side of the side cabinet away from the main cabinet, a rain collection device rotatably connected to the inner wall of the heat dissipation square hole by a rotating bolt, a splash-proof device fixedly connected to the inner wall of the side cabinet, a bottom baffle plate fixedly connected to the bottom of the inner wall of the side cabinet, an inclined guide plate fixedly connected to the bottom of the inner wall of the side cabinet, a circulating water cooling device fixedly connected to the inner wall of the main cabinet, an assembly plate fixedly connected to one side of the circulating water cooling device, and a cabinet door rotatably connected to one side of the main cabinet by a rotating bolt.

[0005] The rain collection device includes an arc-shaped concave shell. By setting the arc-shaped concave shell on the inner wall of the side cabinet near the heat dissipation square hole, the rainwater that drifts in is initially intercepted and collected. This prevents the rainwater from directly passing through the heat dissipation square hole and drifting towards the area near the assembly plate when the rain is heavy, thus affecting the use of the electricity meter. The outer side of the arc-shaped concave shell is provided with dust filter holes. By setting the dust filter holes on the surface of the arc-shaped concave shell, mud and debris are intercepted, preventing a large amount of mud and debris from accumulating inside the side cabinet with the flow of rainwater and becoming difficult to handle, thus affecting the use of the electricity meter.

[0006] Multiple heat dissipation holes are provided, and the multiple heat dissipation holes are distributed on one side of the side cabinet. The bottom of the assembly plate is fixedly connected to the inner wall of the main cabinet.

[0007] The bottom of the circulating water cooling device is fixedly connected to the top of the bottom baffle plate, and one side of the bottom baffle plate is fixedly connected to one side of the inclined guide plate.

[0008] One side of the arc-shaped concave shell is fixedly connected to the inner wall of the side cabinet. Multiple dust filter holes are provided, and the multiple dust filter holes are distributed on the outer side of the arc-shaped concave shell.

[0009] The inner wall of the arc-shaped concave shell is rotatably connected to an internal rotating rod via a rotating bolt. A lightweight concave scraper is fixedly connected to the outer side of the internal rotating rod. As the lightweight concave scraper rotates with the internal rotating rod, it scrapes and cleans the inner wall of the arc-shaped concave shell, preventing the accumulation of mud and dust intercepted by the filter holes from being difficult to handle and affecting the ventilation and heat dissipation effect. A lightweight round rod is fixedly connected to the inner side of the lightweight concave scraper. By setting multiple lightweight round rods on the inner side of the lightweight concave scraper, the contact area with wind and rainwater is increased, resulting in greater driving force. This prevents the lightweight concave scraper from having too small a contact area with wind and rainwater, which would result in minimal driving force and poor rotation effect.

[0010] One end of the built-in rotating rod is rotatably connected to the inner wall of the heat dissipation square hole by a rotating bolt. Multiple lightweight concave scrapers are provided, and multiple lightweight concave scrapers are distributed on the built-in rotating rod. Multiple lightweight round rods are provided, and multiple lightweight round rods are distributed on the inner side of the lightweight concave scrapers.

[0011] Furthermore, the splash-proof device includes a vertical fixed plate, on one side of which an electric push rod is fixedly connected. The drive shaft of the electric push rod passes through the vertical fixed plate and is fixedly connected to an arc-shaped pressure plate. By pushing the arc-shaped pressure plate, the arc-shaped sponge is squeezed to drain water, preventing the rainwater absorbed inside the arc-shaped sponge from gradually drying out and affecting the rainwater collection effect. The outer side of the arc-shaped pressure plate has drainage holes. By opening multiple drainage holes on the arc-shaped pressure plate, some rainwater is drained into the cabinet, preventing a large amount of squeezed rainwater from draining into the arc-shaped concave shell and flowing out of the arc-shaped concave shell, making it difficult to collect. The inner side of the arc-shaped pressure plate is fixedly connected to an arc-shaped sponge. The contact between the arc-shaped sponge and the arc-shaped concave shell provides a covering effect for the dust filter holes, preventing the lightweight concave scraper from being pushed inside the arc-shaped concave shell. When the part rotates, it splashes rainwater towards the position near the assembly plate. The outer side of the arc-shaped sponge has an outward circular groove, and the inner wall of the outward circular groove is fixedly connected to a return spring. The return spring drives the arc-shaped sponge to expand and recover through the extension force, preventing the arc-shaped sponge from gradually losing its elasticity and recovery force after being squeezed and compressed repeatedly, which would affect the subsequent water absorption effect. The top of the vertical fixing plate is fixedly connected to the inner wall of the side cabinet. Multiple drainage holes are provided, and multiple drainage holes are distributed on the outer side of the arc-shaped concave shell. Multiple arc-shaped sponges are provided, and multiple arc-shaped sponges are distributed on one side of the vertical fixing plate, aligned with the arc-shaped concave shell. Multiple outward circular grooves are provided, and multiple outward circular grooves are distributed on the outer side of the arc-shaped sponge. One end of the return spring is fixedly connected to the inner side of the arc-shaped pressure plate.

[0012] Furthermore, the circulating water cooling device includes a bottom extension pipe, the top of which is connected to a high-pressure water pump. The top of the high-pressure water pump is connected to a top extension pipe, and the top of the top extension pipe is connected to a concave connecting pipe. A sleeve-type heat-conducting plate is sleeved and fixedly connected to the outside of the concave connecting pipe. A heat-conducting square plate is fixedly connected to one side of the sleeve-type heat-conducting plate. Rainwater is collected to provide water-cooled heat dissipation for the assembly plate, preventing poor ventilation caused by the arc-shaped sponge and the arc-shaped concave shell coming into close contact during rain, thus ensuring proper heat dissipation and affecting the performance. The sleeve-type heat-conducting plate and the heat-conducting square plate on the concave connecting pipe absorb the heat from the assembly plate, preventing the contact area between the circular contact surface of the concave connecting pipe and the assembly plate from being too small. To address the poor heat dissipation effect, the bottom of the concave connecting pipe is connected to a bottom connecting pipe. The rainwater circulation within the bottom connecting pipe, top connecting pipe, concave connecting pipe, and bottom connecting pipe facilitates the removal of absorbed heat, preventing the temperature from gradually rising due to rainwater absorption in a certain area of ​​the concave connecting pipe, which would still be difficult to dissipate and affect the heat dissipation effect. A three-ring sleeve plate is fitted and fixedly connected to the outside of the bottom connecting pipe. The inside of the bottom connecting pipe is fixedly connected to the top of the bottom baffle plate. One side of the heat-conducting square plate is fixedly connected to one side of the assembly plate. The bottom of the bottom connecting pipe is connected to the outside of the bottom connecting pipe. One side of the three-ring sleeve plate is fixedly connected to the inner wall of the main cabinet. The three-ring sleeve plate is fitted onto the high-pressure water pump and fixedly connected to the high-pressure water pump.

[0013] This invention provides a waterproof electrical meter box for outdoor use. It has the following advantages:

[0014] 1. This outdoor waterproof meter box uses an arc-shaped concave shell on the inner wall of the side cabinet near the ventilation holes to initially intercept and collect rainwater. This prevents heavy rain from passing directly through the ventilation holes and drifting towards the area near the mounting plate, affecting the meter's operation. The arc-shaped sponge, in close contact with the arc-shaped concave shell, covers the dust filter holes to prevent rainwater from splashing onto the mounting plate when the lightweight concave scraper rotates inside the arc-shaped concave shell. The collected rainwater is used for water-cooling the mounting plate, preventing poor ventilation caused by the arc-shaped sponge and arc-shaped concave shell in close contact with rainwater, which would hinder heat dissipation from the mounting plate and affect its performance.

[0015] 2. This outdoor waterproof meter box is equipped with a rain collection device. An arc-shaped concave shell is installed on the inner wall of the side cabinet near the ventilation holes to initially intercept and collect incoming rainwater, preventing heavy rain from passing directly through the ventilation holes and drifting towards the area near the mounting plate, thus affecting meter operation. Dust-filtering holes are opened on the surface of the arc-shaped concave shell to intercept mud and debris, preventing large amounts of mud and debris from accumulating inside the side cabinet and affecting meter operation. A lightweight concave scraper, rotating with the built-in rotating rod, scrapes and cleans the inner wall of the arc-shaped concave shell, preventing mud and debris intercepted by the dust-filtering holes from accumulating inside the shell and affecting ventilation and heat dissipation. Multiple lightweight round rods are installed on the inner side of the lightweight concave scraper to increase the contact area with wind and rainwater, resulting in greater driving force and preventing the lightweight concave scraper from having too small a contact area with wind and rainwater, leading to minimal driving force and poor rotation.

[0016] 3. This outdoor waterproof meter box is equipped with a splash-proof device. The curved sponge and the curved concave shell make contact to cover the dust filter holes and prevent rainwater from splashing. This prevents rainwater from being splashed near the mounting plate when the lightweight concave scraper rotates inside the curved concave shell under the force of the sponge. Multiple drainage holes are opened on the curved pressure plate to allow some rainwater to drain into the cabinet. This prevents a large amount of squeezed rainwater from flowing into the curved concave shell and out of the shell, making it difficult to collect. The curved pressure plate is pushed to squeeze the curved sponge to drain water, preventing the rainwater absorbed inside the curved sponge from gradually drying out and affecting the rainwater collection effect. The return spring uses its extension force to drive the curved sponge to expand and recover, preventing the curved sponge from gradually losing its elasticity and recovery force after repeated compression, which would affect the subsequent water absorption effect.

[0017] 4. This outdoor waterproof meter box is equipped with a circulating water cooling device. It uses collected rainwater to cool the assembly plate, preventing poor ventilation caused by the curved sponge and curved concave shell sticking together during rain, which would hinder heat dissipation from the assembly plate and affect its performance. By installing a sleeved heat-conducting plate and a heat-conducting square plate on the concave connecting pipe, the heat of the assembly plate is absorbed, preventing poor heat dissipation due to the small contact area between the circular contact surface of the concave connecting pipe and the assembly plate. The rainwater circulation in the bottom connecting pipe, top connecting pipe, concave connecting pipe and bottom connecting pipe facilitates the removal of absorbed heat, preventing the temperature from gradually rising due to rainwater absorbing heat in a certain part of the concave connecting pipe, which would still be difficult to dissipate and affect the heat dissipation effect.

[0027] 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.

[0028] Please see Figures 1-4 This invention provides an outdoor waterproof meter box, including a main cabinet 1, with side cabinets 2 fixedly connected to both sides of the main cabinet 1. A heat dissipation square hole 3 is provided on the side of the side cabinet 2 away from the main cabinet 1. A rain collection device 4 is rotatably connected to the inner wall of the heat dissipation square hole 3 via a rotating bolt. A splash-proof device 5 is fixedly connected to the inner wall of the side cabinet 2. A bottom baffle plate 6 is fixedly connected to the bottom of the inner wall of the side cabinet 2. An inclined guide plate 7 is fixedly connected to the bottom of the inner wall of the side cabinet 2. A circulating water cooling device 8 is fixedly connected to the inner wall of the main cabinet 1. An assembly plate 9 is fixedly connected to one side of the circulating water cooling device 8. A cabinet door 10 is rotatably connected to one side of the main cabinet 1 via a rotating bolt.

[0029] The rain collection device 4 includes an arc-shaped concave shell 401, and a dust filter hole 402 is provided on the outer side of the arc-shaped concave shell 401.

[0030] Multiple heat dissipation square holes 3 are provided, and the multiple heat dissipation square holes 3 are distributed on one side of the side cabinet 2. The bottom of the mounting plate 9 is fixedly connected to the inner wall of the main cabinet 1.

[0031] The bottom of the circulating water cooling device 8 is fixedly connected to the top of the bottom baffle plate 6, and one side of the bottom baffle plate 6 is fixedly connected to one side of the inclined guide plate 7.

[0032] One side of the arc-shaped concave shell 401 is fixedly connected to the inner wall of the side cabinet 2. Multiple dust filter holes 402 are provided, and the multiple dust filter holes 402 are distributed on the outside of the arc-shaped concave shell 401.

[0033] The inner wall of the arc-shaped concave shell 401 is rotatably connected to the built-in rotating rod 403 by a rotating bolt. The outer side of the built-in rotating rod 403 is fixedly connected to the lightweight concave scraper 404, and the inner side of the lightweight concave scraper 404 is fixedly connected to the lightweight round rod 405.

[0034] One end of the built-in rotating rod 403 is rotatably connected to the inner wall of the heat dissipation square hole 3 via a rotating bolt. Multiple lightweight concave scraper rods 404 are provided, distributed on the built-in rotating rod 403. Multiple lightweight round rods 405 are provided, distributed inside the lightweight concave scraper rods 404. In use, the meter and wires are assembled onto the mounting plate 9. In rainy weather, rainwater will drift from the heat dissipation square hole 3 on one side of the side cabinet 2 into the rain collection device 4, and then pass through the splash-proof device. 5. The rain collection device 4 is covered with a splash shield to prevent rainwater from splashing onto the meter and wires near the mounting plate 9. At the same time, the rainwater collected by the rain collection device 4 falls onto the inclined guide plate 7 after passing through the splash shield 5. The inclined guide plate 7 is then guided to the position near the bottom baffle plate 6. When enough rainwater has accumulated on the side of the bottom baffle plate 6 near the inclined guide plate 7, the accumulated rainwater is extracted by the circulating water cooling device 8 and circulated to cool the mounting plate 9.

[0035] Rainwater drifts into the arc-shaped concave shell 401 through the heat dissipation square hole 3 on one side of the side cabinet 2 and falls onto the inclined guide plate 7 after passing through the dust filter round holes 402 on the surface of the arc-shaped concave shell 401. The arc-shaped concave shell 401 is set on the inner wall of the side cabinet 2 near the heat dissipation square hole 3 to initially intercept and collect the rainwater. The dust filter round holes 402 on the surface of the arc-shaped concave shell 401 intercept mud and debris. When the rainwater falls and drifts towards the heat dissipation square hole 3, it comes into contact with the lightweight concave scraper 404 and the lightweight round rod 405, and pushes the lightweight concave scraper 404 and the lightweight round rod 405 to drive the built-in rotating rod 403 to rotate. As the lightweight concave scraper 404 rotates with the built-in rotating rod 403, it scrapes and cleans the inner wall of the arc-shaped concave shell 401. The multiple lightweight round rods 405 set on the inner side of the lightweight concave scraper 404 increase the contact area with the wind and rainwater, resulting in greater driving force.

[0036] Please see Figures 1-8 This invention provides an outdoor waterproof meter box: the splash-proof device 5 includes a vertical fixing plate 501, an electric push rod 502 fixedly connected to one side of the vertical fixing plate 501, the drive shaft of the electric push rod 502 passing through the vertical fixing plate 501 and fixedly connected to an arc-shaped pressure plate 503, a drain hole 504 opened on the outer side of the arc-shaped pressure plate 503, an arc-shaped sponge 505 fixedly connected to the inner side of the arc-shaped pressure plate 503, an outwardly opening circular groove 506 opened on the outer side of the arc-shaped sponge 505, and a reset spring fixedly connected to the inner wall of the outwardly opening circular groove 506. Spring 507, the top of the vertical fixing plate 501 is fixedly connected to the inner wall of the side cabinet 2, multiple drain holes 504 are provided, and multiple drain holes 504 are distributed on the outside of the arc-shaped concave shell 401, multiple arc-shaped sponges 505 are provided, and multiple arc-shaped sponges 505 are distributed on one side of the vertical fixing plate 501 aligned with the arc-shaped concave shell 401, multiple outwardly open circular grooves 506 are provided, and multiple outwardly open circular grooves 506 are distributed on the outside of the arc-shaped sponges 505, and one end of the return spring 507 is fixedly connected to the inner side of the arc-shaped pressure plate 503;

[0037] The circulating water cooling device 8 includes a bottom connecting pipe 801, the top of which is connected to a high-pressure water pump 802. The top of the high-pressure water pump 802 is connected to a top connecting pipe 803, and the top of the top connecting pipe 803 is connected to a concave connecting pipe 804. A sleeve-type heat-conducting plate 805 is sleeved and fixedly connected to the outside of the concave connecting pipe 804. A heat-conducting square plate 806 is fixedly connected to one side of the sleeve-type heat-conducting plate 805. The bottom of the concave connecting pipe 804 is connected to a bottom connecting pipe 807, and a three-ring sleeve plate 808 is sleeved and fixedly connected to the outside of the bottom connecting pipe 807. The inside of the bottom connecting pipe 801 is fixedly connected to the top of the bottom baffle plate 6. One side of the heat-conducting square plate 806 is fixedly connected to one side of the mounting plate 9. The bottom of the bottom connecting pipe 807 is connected to the outside of the bottom connecting pipe 801. One side of the ring plate 808 is fixedly connected to the inner wall of the main cabinet 1. The three-ring plate 808 is fitted onto the high-pressure water pump 802 and fixedly connected to it. In use, during rainy weather, the electric push rod 502 drives the drive shaft to push the arc-shaped pressure plate 503 towards the square shape of the arc-shaped concave shell 401. When the arc-shaped pressure plate 503 moves, it drives the inner arc-shaped sponge 505 to move together. When the arc-shaped sponge 505 moves, it stops when its inner side comes into contact with the outer side of the arc-shaped concave shell 401. The contact between the arc-shaped sponge 505 and the arc-shaped concave shell 401 provides a rain-splashing cover for the dust filter holes 402. At this time, the rainwater accumulated in the arc-shaped concave shell 401 will pass through the dust filter holes 402 and be absorbed by the arc-shaped sponge 505. The arc-shaped sponge 505 continuously absorbs rainwater until... When saturated, rainwater overflows from the surface of the curved sponge 505 and drips downwards. When rain stops falling outside the cabinet, the electric push rod 502 pushes the curved pressure plate 503 to compress the curved sponge 505 and the return spring 507 inside the outward-opening circular groove 506. When the curved sponge 505 is compressed, the rainwater inside is discharged outwards. The rainwater inside the curved sponge 505 near the curved concave shell 401 passes through the dust filter holes 402 and accumulates inside the curved concave shell 401. The rainwater inside the curved sponge 505 near the curved pressure plate 503 passes through the drain holes 504 and drips down the curved pressure plate 503 onto the inclined guide plate 7. By opening multiple drain holes 504 on the curved pressure plate 503, some rainwater is discharged into the cabinet. The pressure plate 503 squeezes and drains the arc-shaped sponge 505. After the rainwater absorbed inside the arc-shaped sponge 505 is squeezed out, the electric push rod 502 drives the arc-shaped pressure plate 503 to move away from the arc-shaped concave shell 401. At this time, the return spring 507 on the inner side of the arc-shaped pressure plate 503 loses the squeezing force and returns to its original position. The return spring 507 drives the arc-shaped sponge 505 to expand and recover through the extension force. The high-pressure water pump 802 draws the rainwater accumulated on the inclined guide plate 7 from the bottom extension pipe 801 to the top extension pipe 803. After the rainwater fills the top extension pipe 803, it enters the concave connecting pipe 804. After the rainwater fills the concave connecting pipe 804, it passes through the bottom connecting pipe 807 and enters the bottom extension pipe 801 again. The collected rainwater is used to perform water-cooled heat dissipation on the assembly plate 9.Heat from the assembly plate 9 is absorbed by a sleeve-type heat-conducting plate 805 and a heat-conducting square plate 806 installed on the concave connecting pipe 804. Rainwater flows sequentially from the bottom connecting pipe 801 into the top connecting pipe 803, the concave connecting pipe 804, and the bottom connecting pipe 807, and then returns to the bottom connecting pipe 801 for circulation. This circulation of rainwater within the bottom connecting pipe 801, top connecting pipe 803, concave connecting pipe 804, and bottom connecting pipe 807 facilitates the removal of absorbed heat.

[0038] When the present invention is in operation, the electricity meter and the wire are assembled on the assembly plate 9. When it rains, rainwater will drift into the rain collection device 4 from the heat dissipation square hole 3 on one side of the side cabinet 2. The rain collection device 4 is covered by the anti-splash device 5 to prevent rainwater from splashing onto the electricity meter and the wire near the assembly plate 9. At the same time, the rainwater collected by the rain collection device 4 falls onto the inclined guide plate 7 after passing through the anti-splash device 5. It is then guided by the inclined surface of the inclined guide plate 7 to the position near the bottom baffle plate 6. When enough rainwater has accumulated on the side of the bottom baffle plate 6 near the inclined guide plate 7, the accumulated rainwater is extracted by the circulating water cooling device 8 and circulated to cool the assembly plate 9.

[0039] Rainwater enters the arc-shaped concave shell 401 through the heat dissipation square hole 3 on one side of the side cabinet 2, passes through the dust filter round holes 402 on the surface of the arc-shaped concave shell 401, and falls onto the inclined guide plate 7. The arc-shaped concave shell 401, located on the inner wall of the side cabinet 2 near the heat dissipation square hole 3, provides initial interception and collection of the incoming rainwater. The dust filter round holes 402 on the surface of the arc-shaped concave shell 401 also intercept mud and debris. When the rainwater falls towards the heat dissipation square hole 3, it contacts the lightweight concave scraper 404 and lightweight round rod 405, pushing them to rotate the built-in rotating rod 403. As the lightweight concave scraper 404 rotates with the built-in rotating rod 403, it scrapes and cleans the inner wall of the arc-shaped concave shell 401. Multiple lightweight round rods 405 are arranged inside the lightweight concave scraper 404 to increase the contact area with wind and rainwater, thus increasing the pushing force. In rainy weather, the drive shaft is driven by the electric push rod 502 to push the arc-shaped pressure plate 503 towards the square shape of the arc-shaped concave shell 401. When the arc-shaped pressure plate 503 moves, it drives the inner arc-shaped sponge 505 to move together. When the arc-shaped sponge 505 moves, it stops when the inner side of the arc-shaped sponge 505 comes into contact with the outer side of the arc-shaped concave shell 401. The contact between the arc-shaped sponge 505 and the arc-shaped concave shell 401 provides a covering effect to prevent rainwater splashing on the dust filter holes 402. At this time, the rainwater accumulated in the arc-shaped concave shell 401 will pass through the dust filter holes 402 and be absorbed by the arc-shaped sponge 505. When the arc-shaped sponge 505 continuously absorbs rainwater to a saturated state, the rainwater will flow out from the arc-shaped concave shell 401. The rainwater overflows from the surface of the curved sponge 505 and drips downwards. When the rain stops falling outside the cabinet, the electric push rod 502 pushes the curved pressure plate 503 to compress the curved sponge 505 and the return spring 507 in the outwardly opened circular groove 506. When the curved sponge 505 is compressed, the rainwater inside is discharged outwards. The rainwater inside the curved sponge 505 near the curved concave shell 401 passes through the dust filter holes 402 and accumulates inside the curved concave shell 401. The rainwater inside the curved sponge 505 near the curved pressure plate 503 passes through the drain holes 504 and drips down the curved pressure plate 503 onto the inclined guide plate 7. By opening multiple drain holes 504 on the curved pressure plate 503, some rainwater is discharged into the cabinet. By pushing the curved pressure plate 503... The curved sponge 505 is squeezed to drain water. After the rainwater absorbed inside the curved sponge 505 is squeezed out, the electric push rod 502 drives the curved pressure plate 503 to move away from the curved concave shell 401. At this time, the return spring 507 on the inner side of the curved pressure plate 503 loses the squeezing force and returns to its original position. The return spring 507 drives the curved sponge 505 to expand and recover through the extension force. The high-pressure water pump 802 draws the rainwater accumulated on the inclined guide plate 7 from the bottom extension pipe 801 to the top extension pipe 803. After the rainwater fills the top extension pipe 803, it enters the concave connecting pipe 804. After the rainwater fills the concave connecting pipe 804, it passes through the bottom connecting pipe 807 and enters the bottom extension pipe 801 again. The collected rainwater is used to perform water-cooled heat dissipation on the assembly plate 9.Heat from the assembly plate 9 is absorbed by a sleeve-type heat-conducting plate 805 and a heat-conducting square plate 806 installed on the concave connecting pipe 804. Rainwater flows sequentially from the bottom connecting pipe 801 into the top connecting pipe 803, the concave connecting pipe 804, and the bottom connecting pipe 807, and then returns to the bottom connecting pipe 801 for circulation. This circulation of rainwater within the bottom connecting pipe 801, top connecting pipe 803, concave connecting pipe 804, and bottom connecting pipe 807 facilitates the removal of absorbed heat.
