Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet with a protective structure. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are characterized by small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental protection effects. They are the control center that directs the rational distribution of electrical energy among various components in the power supply line.

[0003] Publication No. CN118970650A discloses an outdoor power distribution cabinet with a safety protection structure. It uses a rain-collecting platform to catch rainwater. In light rain, rainwater falls into the collecting groove and flows out through the outlet pipe. During heavy rain and strong winds, a large and continuous amount of rainwater falls into the collecting groove, preventing the outlet pipe from draining the water in time. The weight of the rainwater causes the rain-collecting platform to press down, which in turn causes the drive plate to move the rack plate downwards. This, in turn, drives the fan blade hinge shaft to rotate, changing the rain-proof fins from an open state to a closed state, thus sealing the heat dissipation slots and preventing rainwater from entering the main body of the power distribution cabinet, ensuring the safety of its internal electrical components. However, this patent still has the following problems in practical use: Although the outdoor distribution cabinet with a safety protection structure uses a rain-collecting platform to collect rainwater, which can seal the heat dissipation vents when a large amount of rainwater falls continuously into the collecting groove during heavy rain, the rain-collecting platform can only collect rainwater slowly during heavy rain and strong winds. This process takes a certain amount of time, during which rainwater has already entered the distribution cabinet through the heat dissipation vents, causing damage to the distribution cabinet. At the same time, during heavy rain, due to the large amount of rainwater, roads may be flooded, and in severe cases, flood disasters may occur. The distribution cabinet cannot be protected, and it may be submerged when flooded, affecting the safety of the distribution cabinet. Publication number CN112421408A discloses a floating distribution cabinet that uses a floating base to achieve the floating of the distribution cabinet. However, it is not convenient to fix the distribution cabinet. In addition, because the distribution cabinet is heavy, the floating base needs to be large to achieve the floating of the distribution cabinet, thus affecting the installation space of the distribution cabinet.

[0004] Therefore, a power distribution cabinet with a protective structure is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a power distribution cabinet with a protective structure to solve the problem mentioned in the background art, which states that the rain-collecting platform can only collect rainwater slowly, a process that takes a certain amount of time.

At the same time, in heavy rain, due to the large amount of rainwater, roads may be flooded, and in severe cases, flood disasters may occur. The power distribution cabinet cannot be protected, resulting in the power distribution cabinet being submerged when flooding occurs, affecting the safety of the power distribution cabinet in use.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This distribution cabinet with a protective structure uses a controller to control a cooling and air-inflating fan to inflate a floating airbag. When there is water accumulation or flooding, the buoyancy of the floating airbag, combined with the sliding connection between the air-inflating pipe and the floating box, can raise the entire distribution cabinet body, thereby preventing water accumulation or flooding from submerging the distribution cabinet body. When the water level exceeds a certain height, the power-off switch on the top of the support plate contacts the power-off contact, enabling the power-off of the entire distribution cabinet body, thus further protecting the internal components of the distribution cabinet body. The gravity of the rainwater collected by the rainwater collection box drives the support fixing rod and support slider to squeeze the support spring assembly, causing the sealing baffle and rain shelter to descend, which can seal the heat dissipation holes on both sides of the distribution cabinet body. At this time, the controller can control the cooling and air-inflating fan to run at high speed, and air enters the air-inflating pipe through the connection hole, thereby rapidly inflating the floating airbag. The specific details are as follows: 1. By setting up a floating protection mechanism, not only can the unidirectional airflow be achieved using the valve spring assembly and sealing plug inside the one-way valve, but the controller also controls the cooling and air-inflating fan to inflate the floating airbag. In the event of water accumulation or flooding, the buoyancy of the floating airbag, combined with the sliding connection between the air inflator and the floating box, elevates the entire distribution cabinet, preventing water or flooding from submerging the cabinet and damaging its internal electrical components. Furthermore, inflating the floating airbag ensures it can retract when not in use, facilitating its storage and minimizing space occupation, thus improving space utilization. When the water level exceeds a certain height, the power-off switch on the top of the support plate contacts the power-off contact, cutting off power to the entire distribution cabinet. This further protects the internal components of the distribution cabinet. The fixed protective plate can be unfolded using the protective rotating rod, and the rotating protective plate can be unfolded using the connecting hinge. The fixed and rotating protective plates not only protect the floating box but also surround the distribution cabinet body, preventing pedestrians from accidentally touching the distribution cabinet body and causing the risk of electric shock. The fixed protective plate can be fixed by the locking pin and the bottom locking groove of the locking sleeve. The rotating protective plate is equipped with a magnetic block at the end, which can magnetically fix the rotating protective plate when it is stored. By pushing the pressing plate downward, the first connecting rod, the locking sliding sleeve and the locking pin will descend. When the locking pin separates from the locking groove, the fixed protective plate can be quickly unfolded, which is convenient for storing and installing the fixed protective plate. 2. By setting up an air-inflating installation mechanism, rainwater can be collected using a rainwater collection box. During heavy rain, the gravity of the collected rainwater drives the support fixing rod and support slider to compress the support spring assembly, causing the sealing baffle and rain shelter to descend. This seals the ventilation holes on both sides of the distribution cabinet. At this time, the controller can control the cooling air-inflating fan to operate at high speed. Air enters the air-inflating pipe through the connection hole, rapidly inflating the floating airbag. When the floating airbag is full of air, the controller stops the cooling air-inflating fan. The controller is existing technology and can realize the operation of the cooling air-inflating fan. An adjustable slide rail allows the sliding of the adjusting slider and mounting plate. The elastic force of the first clamping spring causes the clamping sliding frame to drive the clamping fixing rod and... The adjustable slide rail is fitted to the sliding block to fix it in place. When the sliding block needs to be moved, pulling the unlocking handle outward moves the clamping slide bracket and clamping fixing rod. When the clamping fixing rod separates from the adjustable slide rail, the sliding block can be moved to adjust the position of the mounting plate. When electrical components need to be installed, pressing the clamping bracket causes the clamping sliding sleeve to move relative to the clamping sliding plate and the clamping plate under the action of the clamping rotating rod. This unfolds the clamping plate, making it easier to place the electrical components onto the clamping bracket. The clamping spring brings the two clamping sliding plates closer together to clamp and fix the electrical components. By rotating the adjusting bolt and under the elastic force of the second clamping spring, the distance between the two clamping plates can be increased to accommodate electrical components of different sizes.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-4 , Figure 9The present invention provides a technical solution: a power distribution cabinet with a protective structure, including a floating protection mechanism 1 and a floating airbag 126 installed inside the floating protection mechanism 1. An air-inflating installation mechanism 2 is provided on the top of the floating protection mechanism 1, and a power distribution cabinet body 209 is provided at the bottom of the air-inflating installation mechanism 2. The floating protection mechanism 1 includes a floating box 101, and air-inflating pipes 102 are fixedly installed around the inside of the floating box 101. A one-way valve 103 is fixedly installed on the inner bottom of the air-inflating pipes 102. A valve spring assembly 104 is provided inside the one-way valve 103, wherein a sealing plug 105 is fixedly installed on the top of the valve spring assembly 104, and a support plate 1 is fixedly installed on the bottom of the air-inflating pipes 102. 06. The floating airbag 126 is fixedly installed at the bottom of the protective rotating rod 120. A power-off switch 107 is fixedly installed at the top center of the support plate 106. A power-off contact 108 is fixedly installed on the inner side of the top of the floating box 101. Support blocks 109 are symmetrically installed inside the floating box 101. Water inlets 110 are provided on both sides of the bottom of the floating box 101. A fixed base 111 is fixedly installed at the bottom of the floating box 101. Fixed bolts 112 are threaded around the inside of the fixed base 111. Locking brackets 113 are symmetrically installed around the top of the floating box 101. Locking sliding rods 114 are fixedly installed inside each locking bracket 113. The outer surface of the locking sliding rods 114... A locking sliding sleeve 115 is slidably connected to the side. A locking spring 116 is fixedly installed at the bottom of the locking sliding sleeve 115, and a locking pin 117 is fixedly installed on the outer side of the locking sliding sleeve 115. A first connecting rod 118 is fixedly installed between the two locking sliding sleeves 115, and a pressing plate 119 is fixedly installed at the top of the first connecting rod 118. The valve spring assembly 104 and the sealing plug 105 inside the one-way valve 103 realize one-way airflow. The controller controls the cooling air blower 214 to inflate the floating airbag 126. When there is water accumulation or flood, the buoyancy of the floating airbag 126 can be used, and under the action of the air inflator 102 slidingly connected to the floating box 101, the airbag 126 can be used. The entire distribution cabinet body 209 is raised to prevent water accumulation or flooding from submerging it and damaging the internal electrical components. Simultaneously, the floating airbag 126 is inflated, ensuring it can retract when not in use for easy storage without taking up too much space, thus improving space utilization. When the water level exceeds a certain height, the power-off switch 107 on the top of the support plate 106 contacts the power-off contact 108, cutting off the power to the entire distribution cabinet body 209 and further protecting the internal components.

[0020] Please see Figure 6-Figure 6 , Figure 9The floating box 101 is symmetrically and rotatably connected to protective rotating rods 120 on all four sides. A fixed protective plate 121 is rotatably connected to the end of each protective rotating rod 120. A locking sleeve 122 is fixedly installed on one side of the top of the fixed protective plate 121. A locking groove 123 is symmetrically formed on the inner bottom side of the locking sleeve 122, and the locking groove 123 engages with a locking pin 117. Connecting hinges 124 are symmetrically and rotatably connected to both sides of the fixed protective plate 121. Rotating protective plates 125 are rotatably connected to the outer sides of both connecting hinges 124. The fixed protective plate 121 can be unfolded using the protective rotating rods 120, and the rotating protective plate 125 can be unfolded using the connecting hinges 124. Through the fixed protective plate 121 and the rotating protective plate 125, the floating box 101 can be protected. The protective plate 121 is secured by a locking pin 117 that engages with the locking groove 123 at the bottom of the locking sleeve 122. A magnetic block at the end of the rotating protective plate 125 allows for magnetic fixation during storage. Pushing down the pressing plate 119 lowers the first connecting rod 118, the locking sliding sleeve 115, and the locking pin 117. When the locking pin 117 separates from the locking groove 123, the protective plate 121 unfolds quickly, facilitating its storage and installation.

[0021] Please see Figures 1-2 , Figures 7-9The air pump installation mechanism 2 includes a rainwater collection tank 201. Drain valves 202 are fixedly installed on both sides of the rainwater collection tank 201. Support rods 203 are fixedly installed around the bottom of the rainwater collection tank 201. Support sliders 204 are fixedly installed at the bottom of the support rods 203. Support spring assemblies 205 are fixedly installed at the bottom of the support sliders 204. Support sleeves 206 are fixedly installed on the outer side of the support spring assemblies 205. The bottom of the rainwater collection tank 201 is symmetrically equipped with... A sealing baffle 207 is installed, and a rain shelter 208 is fixedly installed at the bottom of the sealing baffle 207. The distribution cabinet body 209 is fixedly installed at the bottom of the support sleeve 206 and at the top of the air inflator pipe 102. Ventilation holes 211 are provided at the bottom of the distribution cabinet body 209 near the rain shelter 208. A cabinet door 210 is rotatably connected to the outside of the distribution cabinet body 209. A dustproof net 212 is fixedly installed on the inner top of the distribution cabinet body 209. A heat dissipation bracket 213 is fixedly installed at the bottom of the cabinet body 209 near the dustproof net 212. A heat dissipation air pump 214 is fixedly installed inside the heat dissipation bracket 213. Connection holes 215 are opened around the inside of the distribution cabinet body 209. Rainwater is collected by the rainwater collection box 201. When there is a rainstorm, the gravity of the rainwater collected by the rainwater collection box 201 drives the support fixing rod 203 and the support slider 204 to squeeze the support spring assembly 205, so that the sealing baffle 207 and the rain shelter 208 are lowered, which can close the heat dissipation holes 211 on both sides of the distribution cabinet body 209. At this time, the controller can control the heat dissipation air pump 214 to run at high speed. At this time, air enters the air pump pipe 102 through the connection hole 215, thereby rapidly inflating the floating air bag 126. When the floating air bag 126 is full of air, the controller controls the heat dissipation air pump 214 to stop working. The controller is existing technology and can realize the operation of the heat dissipation air pump 214.

[0022] Please see Figures 9-11The distribution cabinet body 209 has several adjustable slide rails 216 fixedly installed inside. Several adjustable sliders 217 are slidably connected inside the adjustable slide rails 216. First compression springs 218 are symmetrically installed on the outer sides of two adjustable sliders 217. Compression sliding brackets 219 are fixedly installed at the ends of the two first compression springs 218. Compression fixing rods 220 are fixedly installed on both sides of the compression sliding brackets 219. The compression fixing rods 220 are in close contact with the adjustable slide rails 216. A second connecting rod 221 is fixedly installed between the two compression sliding brackets 219. An unlocking handle 222 is fixedly installed on the outer side of the compression sliding brackets 219. The center of one side of the adjustable slider 217... A connecting post 223 is fixedly installed in a position. A mounting plate 224 is fixedly installed at the end of the connecting post 223. A clamping rotating rod 225 is rotatably connected to the outer periphery of the mounting plate 224. A clamping sliding sleeve 226 is rotatably connected to the end of the clamping rotating rod 225. A clamping sliding rod 227 is slidably connected inside the clamping sliding sleeve 226. A clamping spring 228 is fixedly installed on one side of the clamping sliding sleeve 226. A clamping bracket 233 is fixedly installed on the outer side of the clamping sliding rod 227. Clamping sliding plates 229 are fixedly installed on the outer sides of both clamping sliding sleeves 226. Adjusting bolts 230 are threadedly connected inside the clamping sliding plates 229. A second clamping spring 231 is rotatably connected to the end of the device. A clamping plate 232 is fixedly installed on the outer side of the second clamping spring 231. The sliding slide 216 allows the sliding of the adjusting slider 217 and the mounting plate 224. The elastic force of the first clamping spring 218 causes the clamping sliding bracket 219 to drive the clamping fixing rod 220 to engage with the adjusting slide 216, thus fixing the adjusting slider 217. When the adjusting slider 217 needs to be moved, pulling the unlocking handle 222 outwards moves the clamping sliding bracket 219 and the clamping fixing rod 220. When the clamping fixing rod 220 separates from the adjusting slide 216, the adjusting slider 217 can be moved. The movement of 7 facilitates the adjustment of the position of the mounting plate 224. When electrical components need to be installed, by pressing the clamping bracket 233, under the action of the clamping rotating rod 225, the clamping sliding sleeve 226 drives the clamping sliding plate 229 and the pressure plate 232 to move relative to each other, which can unfold the pressure plate 232, making it easier to put the electrical components into the clamping bracket 233. The clamping spring 228 is used to make the two clamping sliding plates 229 on both sides move closer to each other, thereby clamping and fixing the electrical components. By rotating the adjusting bolt 230 and under the elastic force of the second pressure spring 231, the distance between the two pressure plates 232 can be increased, thereby accommodating electrical components of different sizes.

[0023] Working principle: Before using this type of distribution cabinet with a protective structure, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 11As shown, firstly, rainwater is collected using the rainwater collection box 201. During heavy rain, the weight of the collected rainwater in the collection box 201 causes the support rod 203 and support slider 204 to compress the support spring assembly 205, lowering the sealing baffle 207 and rain shelter 208. This seals the heat dissipation holes 211 on both sides of the distribution cabinet body 209. At this time, the controller controls the cooling air blower 214 to operate at high speed. Air enters the air pipe 102 through the connection hole 215, rapidly inflating the floating airbag 126. When the floating airbag 126 is fully inflated, the controller stops the cooling air blower 214. The controller is existing technology and can operate the cooling air blower 214. The unidirectional airflow is achieved using the valve spring assembly 104 and sealing plug 105 inside the one-way valve 103. The controller controls the cooling air blower 214. 4. Inflate the floating airbag 126. When there is water accumulation or flood, the buoyancy of the floating airbag 126, along with the sliding connection between the air inflator 102 and the floating box 101, can raise the entire distribution cabinet body 209, thereby preventing water accumulation or flood from submerging the distribution cabinet body 209 and damaging the electrical components inside the distribution cabinet body 209. At the same time, inflating the floating airbag 126 not only ensures that the floating airbag 126 can be retracted when not in use, making it easy to store the floating airbag 126, but also does not occupy a large amount of space, improving space utilization. When the water level exceeds a certain height, the power-off switch 107 on the top of the support plate 106 contacts the power-off contact 108, which can realize the power-off treatment of the entire distribution cabinet body 209, thereby further protecting the components inside the distribution cabinet body 209.

[0024] Secondly, by setting the adjusting slide rail 216, the adjusting slider 217 and the mounting plate 224 can slide. Utilizing the elastic force of the first clamping spring 218, the clamping sliding bracket 219 drives the clamping fixing rod 220 to engage with the adjusting slide rail 216, thereby fixing the adjusting slider 217. When it is necessary to move the adjusting slider 217, pulling the unlocking handle 222 outwards moves the clamping sliding bracket 219 and the clamping fixing rod 220. When the clamping fixing rod 220 separates from the adjusting slide rail 216, the adjusting slider 217 can be moved, facilitating the adjustment of the mounting plate 224's position. When electrical components need to be installed, pressing the clamping bracket 233 causes the clamping sliding sleeve 226 to move relative to the clamping sliding plate 229 and the pressure plate 232 under the action of the clamping rotating rod 225. This allows the pressure plate 232 to be unfolded, making it easier to place the electrical components onto the clamping bracket 233. The clamping spring 228 brings the two clamping sliding plates 229 closer together, thereby clamping and fixing the electrical components. By rotating the adjusting bolt 230 and under the elastic force of the second pressure spring 231, the distance between the two pressure plates 232 can be increased, thus accommodating electrical components of different sizes.

[0025] Finally, the fixed protective plate 121 can be unfolded using the protective rotating rod 120, and the rotating protective plate 125 can be unfolded using the connecting hinge 124. The fixed protective plate 121 and the rotating protective plate 125 not only protect the floating box 101 but also surround the distribution cabinet body 209, preventing pedestrians from accidentally touching the distribution cabinet body 209 and thus avoiding the risk of electric shock. The locking pin 117 engages with the locking groove 123 at the bottom of the locking sleeve 122, ensuring safe operation. The device is capable of fixing the protective plate 121, and the end of the rotating protective plate 125 is provided with a magnetic block, which can achieve magnetic fixation of the rotating protective plate 125 when it is stored. By pushing the pressing plate 119 downward, the first connecting rod 118, the locking sliding sleeve 115 and the locking pin 117 are driven to descend. When the locking pin 117 is separated from the engaging groove 123, the fixed protective plate 121 can be quickly unfolded, which facilitates the storage and installation of the fixed protective plate 121.
