Abstract
Description
Technical Field
[0001] This invention relates to the field of garden technology, specifically to a power distribution cabinet for gardens that facilitates heat dissipation. Background Technology
[0003] In the process of garden construction, in order to ensure the aesthetics of the garden and the normal operation of facilities such as sprinklers, various decorations and automated irrigation equipment are often provided. Therefore, in order to facilitate power distribution, power distribution cabinets exposed on the lawn can often be seen in the garden.
[0004] When a power distribution cabinet is in use, it needs to be cooled by a water-cooling device to suppress its heat generation. However, during the cooling process, the water-cooling device needs to exchange heat with the hot material frequently, which inevitably causes the water-cooling material to evaporate. The evaporated material will leak through the tiny gaps between the pipes, resulting in the loss of cooling fluid. Over time, the water-cooling material will no longer be able to meet the cooling requirements, which will cause the temperature of the power distribution cabinet to rise, causing the internal electronic components to overheat and be damaged, thus affecting the safe use of the entire power distribution cabinet. Summary of the Invention

[0008] In some optional embodiments, the hydro-cooled mechanism comprises a transmission pipe, an acceleration pipe, a flow channel, multiple rotating channels, multiple water wheels, multiple air-cooling channels, and multiple cooling fans. One end of the transmission pipe is connected to the central housing, and the other end of the transmission pipe is connected to the acceleration pipe. The rotating channels and the flow channels are both located within the main body of the power distribution cabinet. The acceleration pipe is connected to one end of the flow channel. Multiple rotating channels are arranged sequentially along the extension direction of the flow channel. The water wheels are rotatably disposed within the rotating channels. Multiple air-cooling channels are all located within the main body of the power distribution cabinet. The cooling fans are rotatably disposed within the air-cooling channels. The water wheels are drivenly connected to the cooling fans. The air outlet of the air-cooling channel faces the power distribution components. The diameter of the transmission tube is larger than the diameter of the acceleration tube.
[0009] In some optional embodiments, the distribution cabinet body has multiple side heat dissipation holes on the side away from the supplementary shell. Multiple rainproof plates are movably hinged to the distribution cabinet body. The rainproof plates are arranged correspondingly at the side heat dissipation holes for opening and closing the side heat dissipation holes. An elastic element is provided between the rainproof plate and the side heat dissipation hole. A baffle plate is provided inside the side heat dissipation hole, located on the side of the rainproof plate facing outward from the side heat dissipation hole. An electromagnet is provided on the side of the baffle plate facing the rainproof plate. A water immersion sensor is provided inside the central shell, and the water immersion sensor is signal connected to the multiple electromagnets.
[0010] In some alternative embodiments, a filter screen is provided inside the water inlet of the collection shell, and the flow port is located in the direction of the filter screen and is funnel-shaped.

[0016] Compared to existing technologies, the garden-use power distribution cabinet of the present invention can be supplemented by external rainwater when the water used for cooling is insufficient, thereby preventing the water cooling circulation from running out and ensuring that the water cooling device can operate continuously. This allows the power distribution cabinet body and power distribution components to maintain the optimal operating temperature and prevent damage caused by overheating. When water inside the central housing cannot be discharged through the flow port, the excess water can be transferred to the flow channel through the transmission pipe and acceleration pipe. When flowing through the flow channel, the impact force of the water flow drives multiple water wheels to rotate, and simultaneously drives multiple cooling fans to rotate. The air force generated by the cooling fans provides air cooling for the inside of the power distribution cabinet body, further reducing the heat inside the power distribution cabinet body.

[0024] Please see Figures 1 to 2 One embodiment of the present invention provides a power distribution cabinet for garden use that facilitates heat dissipation, comprising: a power distribution cabinet body 1.
[0025] The main body of the power distribution cabinet 1 is equipped with power distribution components 102. Multiple heat dissipation fins 205 are connected to one side of the main body of the power distribution cabinet 1. Several connectors are provided on one side of the main body of the power distribution cabinet 1, and water tank 201 is connected to the connectors. Several water cooling pipes 202 are connected to the water tank 201. The two ends of the water cooling pipes 202 are connected to the top and bottom of the water tank 201, respectively. Part of the water cooling pipes 202 are inserted through multiple heat dissipation fins 205. A self-replenishing structure is provided on one side of the water tank 201. The self-replenishing mechanism is used to replenish external rainwater into the water tank 201. A water-driven air-cooling mechanism is provided inside the main body of the power distribution cabinet 1. The water-driven air-cooling mechanism is connected to the self-replenishing mechanism. The water-driven air-cooling mechanism is used to convert the impact force of the water flow from the self-replenishing mechanism into air-cooling power and dissipate heat from the main body of the power distribution cabinet 1 through air cooling.
[0026] Please see Figures 3 to 4The specific structure of the self-replenishing mechanism can be designed according to actual needs. For example, in some optional embodiments, the self-replenishing mechanism includes a replenishment shell 3, a water passage channel, a movable block 307, a movable rod 304, a buoy plate 303, a water passage plate 308, a sealing block 309, a sealing groove 310, a flow port 311, and a central shell 302. The replenishment shell 3 is connected to one end of the water tank 201. The water passage channel is opened on one inner wall of the replenishment shell 3 and communicates with the water tank 201. The movable block 307 is slidably connected in the water passage channel. The movable rod 304 is located away from the replenishment shell 307. On one side of shell 3, buoy plate 303 is connected to one end of movable rod 304. Water passage plate 308 is vertically and flexibly installed inside supplement shell 3 and connected to one side of movable block 307. Water passage plate 308 is provided with water passage. Central shell 302 is installed at the upper end of supplement shell 3. Water inlet is provided at the top of central shell 302. Sealing groove 310 is opened on the upper inner wall of supplement shell 3. Sealing block 309 is installed on the top of water passage plate 308 and located above water passage. Flow port 311 is opened on the lower inner wall of central shell 302 and communicates with supplement shell 3 through sealing groove 310.
[0027] The working principle of a garden-use power distribution cabinet with easy heat dissipation according to an embodiment of the present invention is explained below: The power distribution device 102 installed in the power distribution cabinet body 1 centrally processes and distributes the current. When the power distribution device 102 is running and generating heat, its heat is conducted to the surface of the power distribution cabinet body 1 and then transferred to the heat dissipation fins 205 for centralized heat dissipation. Water in the water tank 201 is transported through the water cooling pipe 202. When the water flows through the water cooling pipe 202 and passes through multiple heat dissipation fins 205, it can carry away the heat collected by the heat dissipation fins 205, achieving rapid cooling. This cools the power distribution cabinet body 1 and the power distribution device 102, preventing the power distribution device 102 from overheating.
[0028] After the water in the water tank 201 has been used for a period of time, the liquid level inside will drop. The self-replenishing mechanism can replenish the water tank 201 with liquids such as rainwater from the outside to avoid insufficient cooling water.
[0029] When the liquid level inside the water tank 201 drops, it will cause the float plate 303, the movable rod 304, the movable block 307 and the water passage plate 308 to drop synchronously. At this time, the sealing block 309 is separated from the sealing groove 310 and is located below the sealing groove 310. In rainy weather, the rainwater falls into the collection shell 302 through the water inlet at the top of the collection shell 302 for collection. Then, the rainwater in the collection shell 302 passes through the flow port 311 and the sealing groove 310 in sequence and enters the replenishment shell 3. The flowing water passes through the water passage in the middle of the water passage plate 308 and then flows into the water tank 201 through the water passage, thereby replenishing the cooling water. The water tank 201 and the replenishment shell 3 are connected by a water channel, and the liquid levels in both are at the same height. Therefore, when the liquid level in the water tank 201 rises due to the replenishment of cooling water, the liquid level in the replenishment shell 3 will also rise. The float plate 303 will rise along with the liquid level in the water tank 201, and the water channel plate 308, sealing block 309 and other structures will also rise together. After the cooling water is replenished sufficiently and the liquid level rises to the appropriate position, the sealing block 309 will rise to the position where it engages with the sealing groove 310. At this time, rainwater in the collection shell 302 will be unable to continue to enter, preventing the water tank 201 from being over-replenished with cooling water.
[0030] Through the above design, the device can be supplemented by external rainwater when the water used for cooling is insufficient, thereby preventing the cooling water used in the water cooling cycle from evaporating during use and causing insufficient cooling water. This ensures that the cooling water in the water cooling cycle formed by the water tank 201 and the water cooling pipe 202 is sufficient to meet the operating requirements, so that the power distribution cabinet body 1 and the power distribution device 102 can maintain the optimal operating temperature and prevent damage caused by overheating.
[0031] Preferably, multiple elastic telescopic rods are fixedly connected to the lower end of the water-passing plate 308, and a sealing plate is fixedly connected to the lower end of the multiple elastic telescopic rods. The sealing plate can be pulled to the lower end of the water-passing plate 308 by the tension of the elastic telescopic rods. In actual use, after the liquid level drops, the sealing block 309 drops and disengages from the sealing groove 310. At this time, the tension of the elastic telescopic rods and the buoyancy of the sealing plate will cause the sealing plate to rise to the position of closing the water outlet of the water-passing plate 308, preventing the cooling water from leaking upward through the water outlet of the water-passing plate 308. If the water outlet of the water-passing plate 308 is closed and blocked, the cooling water inside the replenishment shell 3 will inevitably evaporate and detach from the water outlet, and then escape through the sealing groove 310 and the collection shell 302, especially under high temperature conditions.
[0032] After the rainwater collected in the collection shell 302 flows into the replenishment shell 3, the thrust generated by the downward flow of water and the gravity of the water itself can push the sealing plate downward, causing the sealing plate to descend and open the water outlet. The water can then flow through the water outlet to the bottom of the water outlet plate 308, and then enter the water tank 201 from the water outlet trough.
[0033] Preferably, one end of the power distribution cabinet body 1 is movably hinged with a switch door 101, which can be used to open or close the power distribution cabinet body 1.
[0034] Please see Figure 3 and Figure 5 In some optional embodiments, the hydro-cooled mechanism comprises a transmission pipe 5, an acceleration pipe 501, a flow channel 502, multiple rotating channels, multiple water wheels 504, multiple air-cooling channels, and multiple cooling fans 505. One end of the transmission pipe 5 is connected to the central housing 302, and the other end of the transmission pipe 5 is connected to the acceleration pipe 501. The rotating channels and the flow channel 502 are both opened inside the power distribution cabinet body 1. The acceleration pipe 501 is connected to one end of the flow channel 502. Multiple rotating channels are arranged sequentially along the extension direction of the flow channel 502. The water wheels 504 are rotatably arranged in the rotating channels. Multiple air-cooling channels are all opened inside the power distribution cabinet body 1. The cooling fans 505 are rotatably arranged in the air-cooling channels. The water wheels 504 and the cooling fans 505 are connected by a drive. The air outlet of the air-cooling channel faces the power distribution device 102.
[0035] After the water tank 201 is filled to a suitable liquid level, causing the sealing block 309 to block the sealing groove 310, the water inside the central shell 302 cannot enter the replenishment shell 3 through the flow port 311. However, rainwater continues to fall and will still enter the central shell 302. At this time, the water in the central shell 302 can be transferred to the flow channel 502 through the transmission pipe 5 and the acceleration pipe 501. When flowing through the flow channel 502, the impact force of the water flow drives multiple water wheels 504 to rotate, and simultaneously drives multiple cooling fans 505 to rotate. The air force generated by the cooling fans 505 provides air cooling for the inside of the distribution cabinet body 1, further reducing the heat inside the distribution cabinet body 1. The arrangement of the water wheels 504 relative to the flow channel 502 can be designed according to actual needs. For example, part of the water wheel 504 can extend into the flow channel 502, so that the water flow can quickly drive the water wheel 504 to rotate. Preferably, the flow channel 502 can be gradually inclined downward in a direction away from the acceleration tube 501, so that water can flow rapidly and avoid water stagnation in the flow channel 502.
[0036] In this embodiment, the water wheel 504 is rotatably engaged with the inner wall of the rotating groove via a rotating shaft, while the cooling fan 505 is fixedly connected to the rotating shaft, thereby realizing the transmission between the water wheel 504 and the cooling fan 505.
[0037] The diameter of the transmission pipe 5 is larger than that of the acceleration pipe 501. When rainwater enters the acceleration pipe 501 through the transmission pipe 5, the flow speed of the rainwater can be increased due to the gradual reduction of space, which in turn drives the water wheel 504 to rotate faster and increases the wind power of the cooling fan 505.
[0038] Preferably, a filter plate 506 is provided at the air outlet of the multiple air-cooled slots. The filter plate 506 can prevent debris from entering the air-cooled slots and interfering with the rotation of the cooling fan 505.
[0039] Please see Figure 6 and Figure 7 In some optional embodiments, the distribution cabinet body 1 has multiple side ventilation holes 401 on the side away from the supplementary housing 3. Multiple rainproof plates 404 are movably hinged to the distribution cabinet body 1, and the rainproof plates 404 are correspondingly arranged at the side ventilation holes 401 for opening and closing the side ventilation holes 401. An elastic element is provided between the rainproof plate 404 and the side ventilation hole 401. A baffle plate 402 is provided inside the side ventilation hole 401, located on the side of the rainproof plate 404 facing outwards from the side ventilation hole 401. An electromagnet 403 is provided on the side of the baffle plate 402 facing the rainproof plate 404. A water immersion sensor 4 is provided inside the central housing 302, and the water immersion sensor 4 is signal-connected to the multiple electromagnets 403. The water immersion sensor 4 needs to be positioned higher than the opening height of the delivery pipe.
[0040] The rainproof plate 404 is initially arranged at an angle, with the side ventilation holes 401 open. This allows air inside the distribution cabinet body 1 to dissipate, improving heat dissipation and preventing rainwater from entering. When there is heavy rain outside, the central housing 302 will inevitably be filled with water. This is detected by the water immersion sensor 4. When the water immersion sensor 4 detects that the central housing 302 is full of water, it transmits a signal to the electromagnet 403. At this time, the electromagnet 403 is energized and generates an attractive force, causing the electromagnet 403 to attract the rainproof plate 404 to the side of the baffle plate 402, thereby closing the side ventilation holes 401 and preventing rainwater from entering the side ventilation holes 401 during heavy rain. At this time, the elastic element will undergo elastic deformation.
[0041] After the rain stops, the water inside the collection shell 302 will be transported away by the delivery pipe. When the water immersion sensor 4 detects that there is no water at the corresponding height inside the collection shell 302, it will transmit a signal to the electromagnet 403, causing the electromagnet 403 to shut off. At this time, the electromagnet 403 will release its attraction to the rainproof plate 404. Then, the elastic force of the elastic element will drive the rainproof plate 404 to rotate away from the blocking plate 402, restoring it to its tilted position. Since the rainproof plate 404 opens the side heat dissipation hole 401, it facilitates the subsequent airflow through the side heat dissipation hole 401 for heat dissipation. The elastic element can be a torsion spring or other suitable elastic structure, and is not limited to this example.
[0042] In some optional embodiments, a filter screen 301 is provided inside the water inlet of the collection shell 302 to prevent foreign objects from entering the collection shell 302. The flow port 311 is located in the direction of the filter screen 301 and is funnel-shaped to facilitate the rapid flow of water into the replenishment shell 3.
[0043] In some alternative embodiments, a folding plate 312 connects the upper inner wall of the water channel and the upper end of the movable block 307. The folding plate 312 closes the communication between the portion of the water channel above the movable block 307 and the replenishment shell 3. By blocking the water channel with the folding plate 312, water can only reach the bottom of the water channel 308 from its outlet before entering the water tank 201. During normal use, when water evaporates in the water tank 201, the folding plate 312 prevents water vapor from entering the replenishment shell 3, thus avoiding water loss, especially at higher temperatures. The folding plate 312 functions similarly to the aforementioned sealing plate, both preventing water vapor escape.
[0044] In some optional embodiments, the inner wall of the water tank 201 is provided with two mounting blocks 305, and a vertical guide rod 306 is connected between the two mounting blocks 305. A guide hole is provided at the upper end of the movable rod 304, and the movable rod 304 slides with the vertical guide rod 306 through the guide hole. When the movable rod 304 moves up and down, it can slide along the vertical guide rod 306 through the guide hole, thereby improving the stability of the up and down movement of the movable rod 304.
[0045] In some alternative embodiments, a filter membrane is provided inside the replenishment shell 3. The filter membrane filters rainwater passing through the replenishment shell 3, thereby filtering out solid particles mixed in with the rainwater. The pore size of the filter membrane can be designed according to specific needs, for example, the pore size of the filter membrane is 0.01 micrometers to 0.1 micrometers.
[0046] In some optional embodiments, the lower end of the power distribution cabinet body 1 is provided with a plurality of bottom heat dissipation holes 503. The bottom heat dissipation holes 503 allow air circulation between the inside and outside of the power distribution cabinet body 1, thereby further improving the heat dissipation efficiency. Moreover, the bottom heat dissipation holes 503 are located at the bottom of the power distribution cabinet body 1, which can prevent rainwater from entering while dissipating heat.
[0047] In some optional embodiments, multiple water-cooling pipes 202 are connected to a self-priming pump 203, and a protective shell 2 is provided on the main body of the distribution cabinet 1. The heat dissipation fins 205 and parts of the water-cooling pipes 202 are arranged inside the protective shell 2. The self-priming pump 203 can draw cooling water from the water tank 201 and circulate it through the water-cooling pipes 202 for heat dissipation, while the protective shell 2 can protect the heat dissipation fins 205 and prevent them from contacting the outside environment.
[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
