Description

Technical Field

[0001] The invention belongs to the technical field of intelligent power distribution equipment, and in particular relates to a high-voltage power distribution cabinet with a preinstalled protection structure. Background Art

[0002] High-voltage distribution cabinets are usually equipped with transformers, which often generate a lot of heat when working. If this heat cannot be dissipated effectively and in time, the temperature of the transformer will rise rapidly, causing serious damage to its body. Once the transformer is damaged, it is likely to cause a short circuit fault, which will not only affect the normal operation of the high-voltage distribution cabinet, but also have a serious impact on the power transmission and distribution system of the entire power grid, thereby reducing the use effect of the entire system. Therefore, it is very important to ensure the heat dissipation effect of the transformer.

[0003] Chinese patent CN218569668U discloses a pre-installed high-voltage distribution cabinet protection device, including a distribution box, a mounting rear shell is fixedly connected to the back of the distribution box, a mounting opening is opened on the front of the distribution box, a mounting door is arranged inside the mounting opening, the surface of the distribution box is rotatably connected to the mounting door through hinges, both sides of the inner wall of the distribution box are fixedly connected to mounting hollow shells, two mounting fans are fixedly connected to the top of the distribution box, the air outlet of the mounting fan is fixedly connected to a mounting pipe, the end of the mounting pipe passes through the distribution box and the mounting hollow shell and extends to the inside of the mounting hollow shell, and the side wall of the mounting hollow shell is connected to a plurality of adjustment components; two placement plates are fixedly connected between the two mounting hollow shells, a placement groove is opened at the bottom of the placement plate, a heat sink is arranged inside the placement groove, both sides of the outer side wall of the heat sink are fixedly connected to limit support plates, and the bottom of the placement plate is connected to a limit component for limiting the movement of the limit support plate.

[0004] Although the above scheme can dissipate heat for the high-voltage distribution cabinet, it requires additional electric drive and has high energy consumption. If water cooling is used for cooling, the traditional water cooling system needs to continuously introduce water into the pipeline, and the water source needs to be replaced after a period of use, and the demand for water source is large. There is a rainwater collection device in the prior art to recycle water source and reduce the pressure of water source demand, but the existing rainwater collection device has a fixed structure. During daily use, dust will adhere to the rainwater collection device, which will cause the pipeline used to transport water source to be blocked by the continuously accumulated dust, affecting the normal recovery of water source. At the same time, the existing high-voltage distribution cabinet structure is integrated, and its protective structure cannot be replaced according to the actual usage scenario. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a high-voltage distribution cabinet with a preinstalled protection structure in view of the shortcomings of the prior art. In the present invention, when the weather is not rainy, the ventilation inside the shell is maintained by the air cooling unit to reduce the temperature inside the shell. When the weather is rainy, the dust on the inclined plate is cleaned out by the cleaning unit to avoid the situation where the water collection device is blocked by dust when collecting rainwater. At the same time, the air cooling and water cooling can be automatically switched on rainy days and non-rainy days, ensuring that the electrical components in the high-voltage distribution cabinet can both dissipate heat normally and avoid short circuits due to moisture.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1 , Figure 4 and Figure 7 : A high-voltage distribution cabinet with a preinstalled protection structure includes a shell 1, a water collection unit 2 and a cleaning unit 3. The water collection unit 2 includes an inclined plate 21 and a water collection device 22. The inclined plate 21 is rotatably set on the top of the shell 1; the cleaning unit 3 is set on the inclined plate 21, and the cleaning unit 3 cleans the upper part of the inclined plate 21. The inclined plate 21 has a first mode and a second mode. When the inclined plate 21 is in the first mode, the lower end of the inclined plate 21 is connected to the water collection device 22, and the water collection device 22 starts to collect water. When the inclined plate 21 is in the second mode, the inclination direction of the inclined plate 21 is opposite to the inclination direction of the inclined plate 21 when it is in the first mode. The cleaning unit 3 starts and moves from top to bottom along the inclination direction of the inclined plate 21. The inclined plate 21 first selects the second mode and then selects the first mode.

[0032] A water collecting chamber is provided at the top of the housing 1, and the inclined plate 21 is rotatably disposed in the water collecting chamber. Before the water collecting device 22 collects water, the inclined plate 21 will first switch to the second mode and then switch to the first mode. This is because in daily use, regardless of whether the inclined plate 21 is in the first mode or the second mode, dust will fall on the inclined plate 21. On rainy days, if the inclined plate 21 collects water at this time (that is, when the inclined plate 21 is in the first mode), the dust on the inclined plate 21 will flow into the water collecting device 22 under the flushing of rainwater, which can easily cause the water collecting device 22 to be blocked. The water collecting device 22 includes a water collecting pipe 221 and a water collecting box 222. The water collecting box 222 is arranged at the bottom of the shell 1. The two ends of the water collecting pipe 221 are communicated with the water collecting chamber and the water collecting box 222 respectively. It is worth noting that since the inclination direction of the inclined plate 21 in the first mode and the second mode is opposite, and the water collecting device 22 starts to collect water when the inclined plate 21 is in the first mode, the water collecting pipe 221 in the water collecting device 22 will be communicated with the water collecting chamber only when the inclined plate 21 is in the first mode, and the place where the water collecting pipe 221 and the water collecting chamber are connected to each other is located at the lower end of the inclined plate 21, and when the inclined plate 21 is in the second mode, the inclination direction of the inclined plate 21 is opposite to that of the inclined plate 21. The direction of the inclined plate 21 changes, and the originally lower end of the inclined plate 21 rises, so that the rainwater located on the upper part of the inclined plate 21 cannot be discharged smoothly from the water collecting pipe 221. Before collecting water, the inclined plate 21 is placed in the second mode first, so that the dust on the inclined plate 21 can be cleaned by the cleaning unit 3 before collecting water, so as to prevent dust from entering the water collecting device 22. After the cleaning unit 3 completes the cleaning, the inclined plate 21 switches to the first mode. At this time, the inclined plate 21 can guide the collected rainwater into the water collecting device 22, ensuring that the high-voltage distribution cabinet will not bring dust into the pipeline when collecting rainwater, thereby causing the water collecting device 22 to be blocked.

[0033] Reference Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 : The cleaning unit 3 includes a driving device 31 and a cleaning plate 32; the driving device 31 is arranged at the end of the inclined plate 21; the cleaning plate 32 is slidably arranged on the upper part of the inclined plate 21 along the length direction of the inclined plate 21, and the cleaning plate 32 contacts the upper part of the inclined plate 21. The driving device 31 is used to drive the cleaning plate 32 to move. A discharge groove 11 is opened through the side wall of the shell 1 at the lower end of the inclined plate 21 in the second mode of the inclined plate 21.

[0034] The driving device 31 includes a rotating driving device 311, a threaded rod 312 and a mounting plate 313. The rotating driving device 311 is arranged on the upper part of the inclined plate 21 along the length direction of the inclined plate 21. The mounting plate 313 is fixedly arranged on the upper part of the inclined plate 21. The threaded rod 312 passes through the mounting plate 313 along the length direction of the inclined plate 21. The output end of the rotating driving device 311 is fixedly connected to the end of the threaded rod 312. The threaded rod 312 passes through the cleaning plate 32 along the length direction of the inclined plate 21. The threaded rod 312 is threadedly matched with the cleaning plate 32. The rotating driving device 311 is preferably a servo motor. When the tilting plate 21 needs to be in the second mode, the rotation driving device 311 is started, and the rotation driving device 311 drives the threaded rod 312 to rotate. Since the threaded rod 312 is threadedly matched with the cleaning plate 32, after the threaded rod 312 rotates, the cleaning plate 32 moves on the tilting plate 21 along the length direction of the tilting plate 21. It is worth noting that the upper part of the tilting plate 21 is always in contact with the bottom of the cleaning plate 32. In this way, when the cleaning plate 32 moves on the upper part of the tilting plate 21, the cleaning plate 32 can scrape off the dust on the surface of the tilting plate 21, and the scraped dust is discharged through the discharge groove 11.

[0035] Reference Figure 4 and Figure 5 The cleaning unit 3 further comprises a switching device 33, which is disposed below the inclined plate 21 and is used to change the inclination direction of the inclined plate 21.

[0036] The switching device 33 includes a lifting component 331 and a reversing valve 332. Two lifting components 331 are provided. The two lifting components 331 are symmetrically arranged about the rotation of the inclined plate 21. The two lifting components 331 are both located below the inclined plate 21. Only one of the two lifting components 331 will be activated at the same time. The control ends of the two lifting components 331 are respectively connected to the two ends of the reversing valve 332. The reversing of the reversing valve 332 enables the two lifting components 331 to move respectively. The lifting component 331 includes a lifting sleeve 3311 and a lifting rod 3312. The lifting sleeve 3311 is arranged below the inclined plate 21 along the height direction of the shell 1. The rod 3312 is slidably set at the upper part of the jacking sleeve 3311 along the extension direction of the jacking sleeve 3311, and a first pump body is set at the input end of the reversing valve 332. The first pump body is connected to the water collecting tank 222. The first pump body pumps the water in the water collecting tank 222 into the reversing valve 332 and finally discharges it into the jacking sleeve 3311, so that the jacking rod 3312 located in the jacking sleeve 3311 rises. Since only one jacking assembly 331 is running at a time, the inclined plate 21 can be tilted, that is, one end of the inclined plate 21 lifted by the jacking rod 3312 gradually rises, so that the inclined plate 21 can switch between the first mode and the second mode.

[0037] Reference Figure 1 and Figure 2 The cleaning unit 3 further comprises a filter assembly 34, which is disposed above the housing 1 and has filter holes.

[0038] When rainwater and leaves fall on the top of the shell 1, the leaves will be intercepted by the filter assembly 34, and the rainwater will pass through the filter assembly 34 and enter the inclined plate 21. The filter assembly 34 includes a filter cover 341 and a guide shell 342. Two guide shells 342 are provided. The two guide shells 342 are respectively arranged on both sides of the upper part of the shell 1. The ends of the two guide shells 342 that are close to each other are lower. The guide shells 342 have a guiding effect on rainwater. The guide shells 342 guide the rainwater into the water collection chamber. The filter cover 341 is arranged on the upper part of the guide shell 342, and the filter hole is arranged on the filter cover 341, so that the leaves can be intercepted by the filter cover 341.

[0039] Reference Figure 7 : The high-voltage distribution cabinet also includes a cooling unit 4, which is arranged on the shell 1.

[0040] The cooling unit 4 is used to reduce the temperature inside the housing 1 .

[0041] Reference Figure 7 and Fig. 9 : The cooling unit 4 includes a water cooling unit 41 and an air cooling unit 42; the water cooling unit 41 is arranged inside the shell 1, and the water cooling unit 41 is interconnected with the water collecting device 22, and the water collecting device 22 circulates water to the water cooling unit 41; the air cooling unit 42 is arranged on the side wall of the shell 1, and a receiver is arranged on the shell 1, and the receiver is used to receive weather conditions. The air cooling unit 42 only operates in non-rainy days. A controller is arranged on the shell 1. When the receiver receives that it is rainy outside, the controller controls the operation of the water collecting unit 2 and the cleaning unit 3 according to the information fed back by the receiver.

[0042] A receiver is provided on the shell 1, and the receiver can receive real-time weather conditions. The weather conditions received by the receiver are connected to the Internet, and the weather conditions displayed on the Internet are transmitted to the receiver in real time. When the weather is not rainy, the air cooling unit 42 is in operation, and the air cooling unit 42 maintains ventilation inside the shell 1, thereby reducing the temperature inside the shell 1. When the weather is rainy, the controller controls the cleaning unit 3 to clean the dust on the inclined plate 21 according to the information fed back by the receiver. At this time, the inclined plate 21 is in the second mode. Due to rainy weather, rainwater dripping on the inclined plate 21 can wet the dust on the inclined plate 21, which is beneficial for the cleaning unit 3 to clean the dust on the inclined plate 21. Then the inclined plate 21 switches to the first mode. At this time, the water collecting chamber is communicated with the water collecting device 22, and the water collecting chamber can guide rainwater to the water collecting device 22. The air cooling unit 42 arranged on the side wall of the shell 1 reduces the temperature inside the shell 1 by ventilation. The water cooling unit 41 includes a water cooling pipe 411, which is a winding tubular structure. Both ends of the water cooling pipe 411 are connected to the water collecting tank 222. The water collecting tank 222 supplies water to the water cooling pipe 411. A second pump body is provided in the water collecting tank 222. The second pump body pumps the water in the water collecting tank 222 into the water cooling pipe 411. On rainy days, the air cooling unit 42 is in a closed state and switches to the water cooling unit 41 for cooling. The heat in the outer shell 1 is absorbed and taken away by the water cooling pipe 411, thereby achieving the effect of cooling the inner shell 1. However, since the water cooling unit 41 needs to consume energy, that is, it needs to pump water to the water cooling pipe 411 for circulation through the second pump body in the water collecting tank 222, so when it is not raining, the water cooling unit 41 can be stopped.

[0043] Reference Figure 2 , Figure 7 and Fig. 9 The air cooling unit 42 includes a vent 421, a baffle 422 and an adjusting device 423; the vent 421 is opened through the side wall of the shell 1; the baffle 422 is rotatably set on the vent 421; the adjusting device 423 is set at the bottom of the shell 1, and the adjusting device 423 has an adjusting cavity. The water collecting device 22 includes a water collecting pipe 221 and a water collecting box 222, the water collecting box 222 is set at the bottom of the shell 1, and the water collecting cavity is stored at the top of the shell 1. The two ends of the water collecting pipe 221 are respectively connected with the water collecting box 222 and the water collecting cavity, and the water flows out from the water collecting pipe 221 through the adjusting cavity to reach the water collecting box 222.

[0044] The regulating device 423 is located at the upper part of the water collecting tank 222. The regulating device 423 includes a regulating box 4231, a floating plate 4232 and a pulling rope 4233. The regulating box 4231 is arranged above the water collecting tank 222. The floating plate 4232 is arranged in the regulating box 4231 to move along the height direction of the shell 1. The two ends of the pulling rope 4233 are respectively connected to the upper part of the floating plate 4232 and the end of the baffle 422 located inside the shell 1. The regulating cavity refers to the regulating box 4231. The distance from the end of the baffle 422 located outside the shell 1 to the hinge of the baffle 422 and the vent 421 is greater than the distance from the end of the baffle 422 located inside the shell 1 to the baffle 4 22 is the distance between the hinge of the vent 421 and the inclined plate 21. In this way, when it rains, the inclined plate 21 is in the first mode, and rainwater flows into the regulating box 4231 through the collecting pipe 221. The water level in the regulating box 4231 continues to rise, causing the floating plate 4232 to rise. In this way, the floating plate 4232 no longer generates a pulling force on the baffle 422 by pulling the rope 4233, and the baffle 422 gradually rotates to a vertical state. Conversely, when the water level in the regulating box 4231 gradually decreases, the floating plate 4232 will also gradually decrease. The floating plate 4232 drives the baffle 422 to rotate by pulling the rope 4233, so that the baffle 422 gradually opens the vent 421.

[0045] Reference Fig.10 : The air cooling unit 42 also includes an overflow device 424, which is connected to the regulating cavity and the water collecting tank 222 respectively. The overflow device 424 is used to discharge excess water in the water collecting pipe 221 into the water collecting tank 222. When the overflow device 424 is activated, the regulating cavity in the regulating device 423 is filled with rainwater, and the regulating device 423 pulls the baffle 422 to a vertical state.

[0046] When the baffle 422 is in a vertical state, the baffle 422 blocks the vent 421, so as to prevent rainwater from entering the interior of the housing 1 through the vent 421 on rainy days. The overflow device 424 includes an overflow pipe 4241 and a first switch valve 4242. The overflow pipe 4241 is an "n"-shaped structure. The two ends of the overflow pipe 4241 are respectively connected to the regulating box 4231 and the water collecting tank 222. The highest position of the overflow pipe 4241 is the same as the highest water level of the regulating box 4231. The first switch valve 4242 is arranged on the overflow pipe 4241. When collecting rainwater, That is, when the inclined plate 21 is in the first mode, the first switch valve 4242 is in an open state, so that the rainwater in the water collecting pipe 221 that is higher than the regulating box 4231 can be discharged to the water collecting box 222 through the overflow pipe 4241. The overflow pipe 4241 is set to ensure that the water in the regulating box 4231 is always full when the excess water in the water collecting pipe 221 is discharged into the water collecting box 222. In this way, the floating plate 4232 located in the regulating box 4231 is always at the highest position of the regulating box 4231, so that the baffle 422 located at the vent 421 always remains in a vertical state.

[0047] Reference Fig.10 The air cooling unit 42 also includes a reset device 425, which is arranged at the lower part of the overflow device 424. The two ends of the reset device 425 are respectively connected to the regulating cavity in the regulating device 423 and the water collecting tank 222. After the reset device 425 is activated, it can drive the baffle 422 to rotate to a horizontal state.

[0048] The reset device 425 includes a drain pipe 4251 and a second switch valve 4252. The drain pipe 4251 is arranged below the overflow pipe 4241. Both ends of the drain pipe 4251 are respectively connected to the regulating box 4231 and the water collecting tank 222. The second switch valve 4252 is arranged on the drain pipe 4251. When the rainfall stops, the vent 421 needs to be opened, so that the water in the regulating box 4231 needs to be discharged. At this time, the first switch valve 4242 is closed, and the second switch valve 4252 is opened, and the water in the regulating box 4231 is discharged from the drain pipe 4251 to the water collecting tank 222. In this way, the floating plate 4232 in the regulating box 4231 also gradually descends. The floating plate 4232 drives the baffle 422 to rotate by pulling the rope 4233, so that the baffle 422 is gradually in a horizontal state, so that the inside and outside of the shell 1 are ventilated.

[0049] Reference Figure 4 , Figure 7 and Fig. 9 The high-voltage power distribution cabinet also includes a protection frame 5, an opening is provided on one side of the shell 1, and mounting grooves are provided on the side walls on both sides of the opening of the shell 1 along the width direction of the shell 1, and the protection frame 5 is slidably arranged in the mounting groove along the extension direction of the mounting groove.

[0050] The material of the protection frame 5 can be selected according to actual use conditions. The protection frame 5 is a rectangular structure. When replacing the protection frame 5, the protection frame 5 can be inserted into the installation slot along the extension direction of the installation slot.
