Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and more specifically, to a distribution cabinet with a lifting and guiding structure for coping with rainfall disasters. Background Art

[0002] As a key component in the power system, the main functions of a distribution cabinet are to receive, distribute, and control electric energy. It integrates components such as circuit breakers, disconnectors, meters, and terminal blocks to effectively manage and protect the circuit. When a rainfall disaster occurs, existing distribution cabinets may face various problems, especially when the waterproof performance is not fully considered in the design or installation. Rainwater may enter the interior of the distribution cabinet through gaps in the cabinet body, loose door seals, or ventilation holes. Once moisture enters the cabinet, electrical components may be damp or even immersed in water, leading to a series of serious consequences.

[0003] Firstly, moisture can cause a short circuit in the circuit. When rainwater comes into contact with live components, it may trigger an instantaneous abnormal current, causing the circuit breaker to trip or the fuse to blow, thereby resulting in a power outage. Secondly, moisture can reduce the insulation performance of electrical components. Insulating materials are prone to failure in a humid environment, increasing the risk of electric leakage and threatening the safety of operators. In addition, metal components are prone to corrosion in a humid environment, especially terminal blocks and connectors. Corrosion reduces their electrical conductivity, increases the contact resistance, causes local overheating, and even leads to a fire.

[0004] Existing distribution cabinets usually rely more on their own protection designs to resist the intrusion of a small amount of moisture. For some distribution cabinets located in low-lying areas, when a rainfall disaster occurs, a large amount of rainwater is likely to accumulate and flood the distribution cabinet, causing the cabinet to be soaked in water, damaging the internal electrical components, and it is not convenient to lift the distribution cabinet; at the same time, during long-term soaking, impurities and moisture in the water may also cause corrosion of metal components, shortening the service life of the equipment, and it is not convenient to divert and discharge the accumulated water.

[0039] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Example 1, please refer toFigures 1-6 As shown, the purpose of this embodiment is to provide a lifting diversion type power distribution cabinet body 1 for dealing with rainfall disasters, including the power distribution cabinet body 1, the power distribution cabinet body 1 includes a top plate 11 and a base 13, a door plate 12 is provided between one set of outer walls opposite to the top plate 11 and the base 13, and a heat dissipation device 14 is provided between the other set of outer walls opposite to the top plate 11 and the base 13;

[0041] The heat dissipation device 14 includes a heat dissipation plate 140, which is fixedly connected between the top plate 11 and the base 13. A plurality of heat dissipation holes are provided inside the heat dissipation plate 140, and a guide assembly 141 is provided inside each of the plurality of heat dissipation holes of the heat dissipation plate 140. A floating assembly 142 is provided inside the heat dissipation plate 140, and the floating assembly 142 includes a baffle 1420. A floating strip 1421 is provided at the end of the baffle 1420 that passes through the outer wall of one side of the heat dissipation plate 140.

[0042] The guide assembly 141 is used to intercept and receive rainwater that enters the power distribution cabinet body 1 in advance during rainy weather. When the power distribution cabinet body 1 is flooded around, the floating bar 1421 is acted on by the buoyancy of the rising water level to move upward, driving the baffle 1420 to move upward inside the heat dissipation plate 140, blocking the heat dissipation holes of the heat dissipation plate 140 to prevent water from entering the power distribution cabinet body 1. In addition, the baffle 1420 also pushes the guide assembly 141 to rotate during the upward movement to discharge the rainwater accumulated inside the guide assembly 141.

[0043] The outer wall of the heat dissipation plate 140 is provided with a plurality of square heat dissipation holes near the bottom, and the inner wall of the heat dissipation plate 140 is provided with a plurality of rectangular grooves in a horizontal direction opposite to the plurality of square heat dissipation holes;

[0044] First, the specific structure of the guide assembly 141 is disclosed. The guide assembly 141 includes a collection box 1410. A plurality of collection boxes 1410 are respectively movably connected to a plurality of square heat dissipation holes. A rotating shaft 1411 is provided on the outer wall of the collection box 1410. The rotating shaft 1411 is movably connected to the square heat dissipation holes of the heat dissipation plate 140.

[0045] See also Figure 4 and Figure 7 As shown, by clamping the collecting box 1410 between the square heat dissipation holes of the heat dissipation plate 140 and the baffle 1420, when the inner bottom of the collecting box 1410 is in a parallel state with the square heat dissipation holes of the heat dissipation plate 140, in the case of small rainfall, if rainwater splashes into the inside of the power distribution cabinet body 1 through the square heat dissipation holes of the heat dissipation plate 140, the rainwater will first touch the collecting box 1410 when passing through the square heat dissipation holes of the heat dissipation plate 140, effectively intercepting the rainwater splashing into the inside of the power distribution cabinet body 1 through the heat dissipation holes, avoiding rainwater from directly contacting the electrical equipment in the cabinet, preventing the equipment from being damp, short-circuited or corroded, and ensuring the normal operation of the equipment;

[0046] The top of the collection box 1410 and the outer wall of the side close to the square heat dissipation holes are both designed with openings. The collection box 1410 is used to block and collect the rainwater entering from the square heat dissipation holes; refer to Figure 4 As shown, the rainwater is intercepted by the collection box 1410 and accumulates inside the collection box 1410, so that while the collection box 1410 intercepts the rainwater, it will not completely block the heat dissipation holes, ensuring that when intercepting the rainwater, the heat dissipation holes can still maintain a certain ventilation and heat dissipation function, avoiding damage to the equipment due to overheating;

[0047] Secondly, the specific structure of the floating component 142 is disclosed. The floating component 142 includes a baffle 1420. The baffle 1420 is movably arranged inside the heat dissipation plate 140 near multiple rectangular grooves. On the outer wall of the side of the baffle 1420 close to the square heat dissipation holes and near the bottom, there are two bumps. At the end where the bumps of the baffle 1420 pass through the heat dissipation plate 140, there is a floating strip 1421. Near both ends of the top of the floating strip 1421, there are pneumatic components 1422;

[0048] Refer to Figure 8 As shown, when encountering heavy rainfall, the power distribution cabinet body 1 in the low-lying area is easily flooded by accumulated water. At this time, the gradually rising accumulated water will push the floating strip 1421 upward. The floating strip 1421 is a slender cylinder, made of rubber material, and the inside of the floating strip 1421 is filled with gas;

[0049] Due to the low density of the rubber material and the gas filled inside, the floating strip 1421 has high buoyancy, can quickly respond and lift the baffle 1420 when the water level rises, ensuring that the waterproof function of the system is started in time; moreover, the rubber material has good flexibility, can adapt to different water level changes and mechanical movements, is not easily damaged due to frequent up and down movements, and prolongs the service life of the floating strip 1421; at the same time, the rubber material also has good sealing performance, can effectively prevent external accumulated water from seeping into the inside of the floating strip 1421, and ensures that its buoyancy performance is not affected;

[0050] By filling the inside of the floating strip 1421 with gas, its density is much lower than that of water; when the water level around the power distribution cabinet body 1 rises, the floating strip 1421 is affected by the buoyancy of water and begins to rise upward. When the floating strip 1421 moves upward, it drives the baffle 1420 to rise synchronously; after the baffle 1420 rises, the long strip blocking part of it is precisely matched with the long strip groove on the inner wall of the heat dissipation plate 140, blocking the heat dissipation holes and cutting off the circulation relationship between the heat dissipation plate 140 and the inside of the power distribution cabinet body 1 to achieve the waterproof function; when the water level drops, the floating strip 1421 loses the buoyancy support and gradually descends under the action of gravity, driving the baffle 1420 to reset and reopen the heat dissipation holes to restore the heat dissipation function;

[0051] The floating bar 1421 drives the baffle 1420 to move upward. Since there are multiple grooves on the baffle 1420 that are the same size as the rectangular grooves on the inner wall of the heat dissipation plate 140, a collection box 1410 is clamped inside the rectangular grooves of the baffle 1420. The baffle 1420 can open and close the flow state of the multiple rectangular grooves of the heat dissipation plate 140; enabling the baffle 1420 to precisely match the structure of the heat dissipation plate 140, ensuring that the baffle 1420 can completely block or open the heat dissipation holes when moving up and down, realizing the efficient control of the flow state of the heat dissipation plate 140; making the long strip blocks between the multiple rectangular grooves of the baffle 1420 block at multiple long strip grooves on the inner wall of the heat dissipation plate 140, thereby blocking the flow relationship between the heat dissipation plate 140 and the inside of the power distribution cabinet body 1;

[0052] When the water accumulates and submerges the power distribution cabinet body 1, it is convenient for the floating bar 1421 to utilize the buoyancy principle of water to achieve automatic response without external energy or manual operation. In sudden floods or heavy rain weather, the system can be quickly started to ensure that the power distribution cabinet body 1 can still be effectively protected in extreme environments; through this dynamic balance design, the requirements of heat dissipation and waterproofing are taken into account. In normal weather, the heat dissipation holes remain open to ensure that the heat inside the power distribution cabinet body 1 is dissipated in a timely manner, avoiding overheating of the equipment; while in the case of water accumulation, the baffle 1420 automatically blocks the heat dissipation holes to give priority to waterproofing and ensure the safety of the equipment;

[0053] Moreover, during the upward movement of the baffle 1420, it will also synchronously push the collection box 1410 to tilt upward and flip, causing the rotating shaft 1411 on the collection box 1410 to rotate inside the heat dissipation plate 140, driving the collection box 1410 to tilt, and pouring the rainwater inside the collection box 1410 to the outside of the heat dissipation plate 140, avoiding the long-term retention of rainwater in the collection box 1410 and reducing the workload of cleaning and maintenance; at the same time, making the collection box 1410 in an inclined state, which can block the rainwater flowing into the heat dissipation plate 140 in advance, enabling the rainwater to flow out along the inclined direction of the collection box 1410, further enhancing the waterproof effect;

[0054] Among them, the height of the collection box 1410 is less than the height of the rectangular grooves in the baffle 1420, which is convenient for the collection box 1410 to move out of the grooves of the baffle 1420 under the upward pushing effect of the baffle 1420 to complete the flipping of the collection box 1410;

[0055] At the same time, a return spring (not shown in the figure) is provided at the rotating shaft 1411 of the collection box 1410. When the collection box 1410 rotates under the pushing effect of the baffle 1420, it will drive the return spring (not shown in the figure) to compress. When the baffle 1420 loses buoyancy and descends, the collection box 1410 loses the extrusion force. At this time, the elastic force of the return spring (not shown in the figure) resets, driving the collection box 1410 to rotate and reset.

[0056] Finally, the specific structure of the pneumatic component 1422 is disclosed. The pneumatic component 1422 includes a valve housing 14220 which is fixedly connected to the outer wall of the floating strip 1421. A pressing plate 14223 is provided near the end inside the valve housing 14220, and a piston 14221 is provided near the middle inside the valve housing 14220. The pressing plate 14223 is coaxially connected to the piston 14221, and an elastic member 14222 is provided between the pressing plate 14223 and the convex block at the center of the valve housing 14220;

[0057] Refer to Figure 9 And Figure 10 As shown, in the case of relatively large rainfall, by continuously hitting the top of the pressing plate 14223 with some raindrops, the pressing plate 14223 drives the inside of the valve housing 14220 downward, compressing the elastic member 14222. At this time, the piston 14221 is pushed downward to convey gas into the floating strip 1421; through the rebound and reset of the elastic member 14222, at this time, the raindrops hit the pressing plate 14223 again, and so on. Through the kinetic energy of the raindrops hitting the pressing plate 14223, the external energy is converted into the filling of the gas inside the floating strip 1421, ensuring that the floating strip 1421 always maintains sufficient buoyancy and can quickly respond and lift the baffle 1420 in the case of water accumulation, thereby realizing the waterproof function;

[0058] When the rainfall is relatively large, the frequency and intensity of the raindrops hitting the pressing plate 14223 increase, and the inflation speed accelerates, ensuring that the floating strip 1421 can be quickly inflated and lift the baffle 1420; when the rainfall is relatively small, the inflation speed slows down to avoid over-inflation. Through this dynamic adjustment mechanism, the system can flexibly adapt to the needs of different rainfall intensities.

[0059] Considering that when intercepting rainwater through the collection box 1410, if the rainfall is large, some rainwater may enter the heat dissipation plate 140. Therefore, grooves are provided at both ends of the base 13 close to the heat dissipation plate 140, and inclined surfaces are provided inside the grooves of the base 13. The base 13 is used to divert the rainwater accumulated at the base 13;

[0060] Since the bottom of the heat dissipation plate 140 is designed to be hollow, it is convenient for the rainwater entering the inside of the heat dissipation plate 140 to flow downward into the grooves of the base 13. On the basis of the collection box 1410 intercepting rainwater, the diversion design of the base 13 serves as a second line of defense, further enhancing the waterproof ability of the system, ensuring that even if some rainwater enters the inside of the heat dissipation plate 140, it can be discharged in time; and through the groove and inclined surface design of the base 13, the rainwater entering the inside of the heat dissipation plate 140 can be quickly diverted and discharged, avoiding the accumulation of rainwater at the heat dissipation plate 140 or the base 13, and reducing the risk of rainwater penetrating into the power distribution cabinet body 1.

[0061] The improvement of this embodiment is that: the design effectively solves the waterproof and heat dissipation problems of the power distribution cabinet body 1 in rainy weather through a graded waterproof mechanism and intelligent automatic response; in the case of small rainfall, the guide component 141 actively intercepts and receives rainwater to prevent it from entering the inside of the power distribution cabinet body 1 through the heat dissipation holes, thereby avoiding moisture, short circuit or corrosion of the equipment, ensuring the normal operation of the equipment and extending its service life; in the case of heavy rainfall, the floating component 142 automatically rises due to the buoyancy of the rising water level, blocks the heat dissipation holes and turns off the heat dissipation function, so that the power distribution cabinet body 1 enters a sealed state, effectively preventing water from entering the inside, and is particularly suitable for low-lying areas or sudden flooding scenarios;

[0062] In addition, the floating component 142 uses the buoyancy principle of water to automatically adjust its position according to the change of water level to achieve the blocking and opening of the heat dissipation holes without external energy or manual operation, thereby improving the reliability and response speed of the system. At the same time, when the floating component 142 rises, the guide component 141 is linked to rotate to discharge the accumulated rainwater, further optimizing the drainage efficiency and ensuring that the system quickly returns to normal after the rain ends.

[0063] The design achieves a dynamic balance between heat dissipation and waterproofing. In normal weather, the heat dissipation holes remain open to ensure that the heat inside the distribution cabinet body 1 is dissipated in time; in rainy weather, the system automatically adjusts the priority according to the rainfall, taking into account both heat dissipation and waterproofing in light rainfall, and giving priority to waterproofing in heavy rainfall to ensure equipment safety.

[0064] In summary, the working principle of this scheme is as follows:

[0065] In rainy weather, the power distribution cabinet body 1 adopts a multi-level waterproof and heat dissipation balance design to ensure that the equipment can be effectively protected under different rainfall intensities; when the rainfall is small, rainwater may splash into the inside of the power distribution cabinet body 1 through the square heat dissipation holes of the heat dissipation plate 140; at this time, the collection box 1410 serves as the first line of defense and preferentially intercepts rainwater; the collection box 1410 is clamped between the heat dissipation plate 140 and the baffle 1420, and its top and the side close to the heat dissipation hole are open, which can effectively collect rainwater entering from the heat dissipation hole and accumulate it inside the collection box 1410;

[0066] The structural design of the collection box 1410 allows it to intercept rainwater without completely blocking the heat dissipation holes, ensuring that the heat dissipation plate 140 can still maintain a certain ventilation and heat dissipation function to prevent the equipment from being damaged due to overheating. This design achieves a dynamic balance between waterproofing and heat dissipation under low rainfall conditions.

[0067] When the rainfall is large or the power distribution cabinet body 1 is in a low-lying area, the surrounding water level gradually rises; at this time, the floating strip 1421 is lifted upward under the buoyancy of water; the floating strip 1421 is made of rubber material, filled with gas inside, and has the characteristics of low density, large buoyancy, good flexibility and strong sealing performance, and can quickly respond to the water level change;

[0068] When the floating strip 1421 moves upward, it drives the baffle 1420 to rise synchronously; there are multiple grooves on the baffle 1420 that are the same size as the rectangular grooves on the inner wall of the heat dissipation plate 140, and the long strip blocking part thereof precisely matches the long strip grooves of the heat dissipation plate 140, completely blocking the heat dissipation holes, cutting off the circulation relationship between the heat dissipation plate 140 and the inside of the power distribution cabinet body 1, making the power distribution cabinet body 1 enter a sealed state to prevent water from entering the inside;

[0069] When the water level drops, the floating strip 1421 loses the buoyancy support, drives the baffle 1420 to reset under the action of gravity, reopens the heat dissipation holes, and restores the heat dissipation function; this automatic response mechanism does not require external energy or manual intervention, can be quickly started in extreme weather, and ensures the safety of the power distribution cabinet body 1;

[0070] Moreover, during the rising process of the baffle 1420, it will also synchronously push the collection box 1410 to tilt and turn upward; the collection box 1410 rotates inside the heat dissipation plate 140 through the rotating shaft 1411, making it tilt, and pouring the accumulated rainwater inside to the outside of the heat dissipation plate 140 to avoid long-term retention of rainwater;

[0071] At the same time, the tilted collection box 1410 can also secondarily block the rainwater that is about to enter the inside of the heat dissipation plate 140, making the rainwater flow out along the tilted direction, further enhancing the waterproof effect; this design not only reduces the workload of cleaning and maintenance, but also optimizes the drainage efficiency;

[0072] When the rainfall is large, some raindrops continuously strike and press the pressure plate 14223, driving the pressure plate 14223 to move downward inside the valve housing 14220, compressing the elastic member 14222, so that the piston 14221 is pushed downward to convey gas into the floating strip 1421;

[0073] When the raindrops stop hitting, the elastic member 14222 rebounds and resets, and the pressure plate 14223 returns to its original position, waiting for the next raindrop to hit; through this reciprocating motion, the system can continuously inflate the floating strip 1421 to ensure its sufficient buoyancy and meet the requirements of different rainfall intensities;

[0074] Considering that in the case of heavy rainfall, some rainwater may break through the interception of the collection box 1410 and enter the inside of the heat dissipation plate 140. By providing grooves at both ends of the base 13 close to the heat dissipation plate 140, and an inclined surface is designed inside the grooves; so that the rainwater entering the inside of the heat dissipation plate 140 flows into the grooves of the base 13 through its hollow design at the bottom and quickly slides down and discharges along the inclined surface, avoiding the accumulation or rise of rainwater at the base 13 and entering the inside of the power distribution cabinet body 1, further enhancing the waterproof ability of the system.
