Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, and more particularly to an intelligent load balancing cable branch box. Background Technology

[0002] Cable distribution boxes are key equipment in power distribution networks, mainly used for branching, switching, and load distribution of cable lines. By monitoring the current of each branch in real time (Hall sensors) and analyzing the load status using edge computing (ARM processors), they dynamically adjust switches (solid-state relays) or impedance to automatically transfer overloaded branch loads to lightly loaded branches. Through 4G / 5G communication and collaborative optimization with the main station, they achieve balanced load distribution, improve efficiency, and prevent overload.

[0003] Long-term overload operation of cable distribution boxes can lead to overheating of cables or joints, causing insulation aging and even melting. Secondly, loose internal connections or poor contact can generate localized high resistance and arcing, resulting in a rapid temperature increase. Furthermore, short-circuit faults caused by aging or damaged cable insulation, or internal water ingress and dampness, can also instantly generate huge currents and heat, leading to spontaneous combustion. Extreme weather conditions (such as lightning strikes) or external mechanical damage causing short-circuit faults are also potential fire hazards. Existing cable distribution boxes can only cool down the cables and cannot extinguish fires in extreme situations. Although the probability of spontaneous combustion in cable distribution boxes is low, because they are usually installed in densely populated areas or critical power supply nodes, a fire could trigger a chain reaction (such as power grid failure or fire spread). Therefore, active fire suppression for cable distribution boxes is an issue that must be considered.

[0004] Furthermore, cable distribution boxes, lacking effective protection, become targets for rodents. Rats typically enter through the cable connection ports at the bottom of the box, and their gnawing on the cables directly damages the insulation, easily causing short circuits. Simultaneously, rat excrement corrodes equipment, increasing the risk of electric shock. Currently used simple baffles or rubber ring seals are prone to aging and deformation after long-term use, failing to provide durable and effective rodent control. Therefore, cable distribution boxes are highly susceptible to severe damage from rodents, even becoming completely unusable, seriously affecting the stability and safety of power supply. More effective rodent control measures are urgently needed to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to solve the fire extinguishing and rodent control problems existing in the background art, and to propose an intelligent load balancing cable branch box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent load-balancing cable branch box, comprising: a branch box, the branch box having a door, the bottom of the branch box being a wiring port, a fire extinguishing structure installed on the inner side of the door, the fire extinguishing structure including a material box fixed inside the door, the material box storing dry powder, the material box employing a heat insulation design to prevent heat from the branch box from being transferred to the dry powder, a first support block and a motor fixed to the material box, a worm gear fixed to the output end of the motor and the worm gear passing through the first support block. The material box is rotatably connected to a hollow discharge pipe. The discharge pipe functions similarly to the rotating shaft, serving both as a rotational mechanism and a discharge mechanism. An air-filled bladder is installed inside the discharge pipe, and worm gears are installed on its exterior. The worm meshes with the worm gears. A hollow disc is fixed to one end of the discharge pipe, and an elastic vibrating plate extending to the outside is fixed to the hollow disc. A rigid rod is fixed to the exterior of the material box. Hollow blades are fixedly connected to the hollow disc, and the hollow blades have a spout. The spout is sealed by the air-filled bladder.

[0007] As a further embodiment of the present invention, the fire extinguishing structure further includes a limiting frame fixed to the front of the hollow blade, a first magnet slidably connected inside the limiting frame, a first spring fixed inside the limiting frame, and one end of the first spring fixedly connected to the first magnet. The bottom of the first magnet is provided with a hollow groove, a miniature electric push rod is installed inside the hollow groove, and a conical blade is fixed to the output end of the electric push rod. The branch box is provided with a rodent-repelling structure.

[0008] As a further embodiment of the present invention, the fire extinguishing structure also includes a hollow box fixed to the bottom of the material bin, a push plate slidably connected inside the hollow box, vermiculite filling the hollow box to the left of the push plate, a second support block fixed to the inner wall of the material bin, a pointed rod slidably connected inside the second support block, one end of the pointed rod being located inside the hollow box and fixedly connected to the push plate, the tip of the pointed rod being located on one side of the plugging airbag, and a hollow tube connected to the vermiculite-filled part of the hollow box, one end of the hollow tube penetrating the discharge bin.

[0009] As a further embodiment of the present invention, the rodent-repelling structure includes a first support rod fixed to the inner wall of the branch box, the first support rod having a cylindrical groove, a second spring and a top rod being disposed inside the cylindrical groove, the top rod passing through the middle of the second spring, an annular pressure plate being fixed to the outside of the top rod, and the pressure plate being slidably connected to the inner wall of the cylindrical groove, and a second magnet being fixed to one end of the top rod.

[0010] As a further embodiment of the present invention, the rodent-repelling structure also includes a second support rod fixed to the inner wall of the branch box. The bottom of the second support rod is provided with a swingable bell. One end of the top rod is in contact with the bell. An elastic swing plate is fixed to the bottom of the second support rod on one side of the bell. The bottom of the elastic swing plate is located inside the wiring port. A colorful cat pattern is engraved on the bottom of the elastic swing plate. The branch box is provided with a cooling component, which is distributed inside and outside the branch box.

[0011] As a further embodiment of the present invention, the cooling component includes a water spray at the top of the outer wall of the branch box and a water collection tank at the bottom. A filter screen is installed at the top of the water collection tank, and a water tank is installed at the bottom of the branch box. The water tank is protected by a water pump and can be buried deep underground. The water pump is not shown in the figure and is equipped with a water delivery pipe. The water delivery pipe enters the interior of the branch box from the wiring port and is connected to the spray nozzle. A drain pipe is connected to the bottom of the water collection tank, and the end of the drain pipe is located inside the water tank. A water guide channel is provided on the outside of the branch box.

[0012] As a further embodiment of the present invention, the cooling component and the hollow blades form an inner and outer cooling structure.

[0013] As a further embodiment of the present invention, a temperature sensor and a smoke sensor are installed inside the branch box.

[0014] As a further embodiment of the present invention, a sprinkler head is installed on the top of the inner cavity of the branch box, and the sprinkler head is connected to the inside of the water tank (not shown in the figure) through a pipe.

[0015] The intelligent load balancing cable branch box proposed in this invention has the following advantages: 1. When the hollow blade rotates, it generates centrifugal force. The first magnet overcomes the elastic force of the first spring and is thrown towards the tip of the hollow blade. The first spring helps the first magnet return to its original position. Simultaneously, the output end of the electric push rod inside the first magnet extends, along with the blade. Because the path of the first magnet, moving under centrifugal force, is exactly along the path of the sealing airbag, the movement of the first magnet will cause the blade to puncture the sealing airbag, causing it to burst open. This opens the dispensing port. At the same time, the branch box reaches a temperature close to the temperature required for vermiculite expansion, nearing its auto-ignition temperature. The vermiculite expands inside the hollow box, pushing the pusher plate and the pointed rod to move. When the pointed rod moves, it punctures the blocking airbag and opens the discharge pipe. Then, the dry powder accumulated in the hopper enters the interior of the hollow box through the discharge pipe. After that, the dry powder in the hollow box enters the interior of the hollow blades. Then, under the action of its rotation, it is discharged from the sprinkling port and thrown into the interior of the branch box. Through the centrifugal force of the rotation of the hollow blades, the dry powder is evenly diffused. The high-speed dry powder is fully mixed with the air to form a dust cloud, which enhances the contact reaction with the flame and accelerates the extinguishing. Under normal heat dissipation conditions, the dry powder will not be thrown out when it is sucked down.

[0016] 2. When the hollow blade rotates, causing magnet number one to overcome the elastic force of spring number one and move towards the tip of the hollow blade, magnet number one will move directly in front of magnet number two. Magnet number one is a strong magnet and is of the same polarity as magnet number two. Therefore, when magnet number one arrives directly in front of magnet number two, the push rod will move within the cylindrical groove of support rod number one due to the repulsive force between like magnets. Then, the pressure plate presses spring number two, which facilitates the return of push rod to its original position. When push rod moves, it strikes the bell, which makes a sound to drive away mice. At the same time, the bell strikes the elastic swing plate, which then swings back and forth at the connection port, scaring away mice that try to climb up through the connection port. In addition, due to the cat pattern on the bottom of the elastic swing plate, mice will see the cat's image clearly, which will frighten them and drive them away. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0021] A smart load-balancing cable distribution box includes: a distribution box 1, with a temperature sensor and a smoke sensor installed inside; a door 2; a wiring port 6 at the bottom of the distribution box 1; a fire extinguishing structure 3 installed inside the door 2; the fire extinguishing structure 3 includes a material box 301 fixed inside the door 2; the material box 301 stores dry powder; the material box 301 is heat-insulated to prevent heat transfer from the distribution box 1 to the dry powder; a first support block 302 and a motor 303 are fixed to the material box 301; a worm gear 304 is fixed to the output end of the motor 303 and passes through the first support block 302; the material box 301 rotates... A hollow discharge pipe 305 is connected. The function of the discharge pipe 305 is the same as that of the rotating shaft. It can be used for both rotation and discharge. A blocking airbag 306 is set inside the discharge pipe 305. A worm gear 307 is set outside the discharge pipe 305. The worm 304 meshes with the worm gear 307. A hollow disc 308 is fixed to one end of the discharge pipe 305. An elastic vibrating plate 309 extending to the outside is fixed to the hollow disc 308. A rigid rod 310 is fixed to the outside of the material box 301. A hollow blade 311 is fixedly connected to the hollow disc 308. The hollow blade 311 is provided with a sprinkling port 312. The sprinkling port 312 is closed by the sealing airbag 313.

[0022] Furthermore, the fire extinguishing structure 3 also includes a limiting frame 314 fixed to the front of the hollow blade 311. A magnet 315 is slidably connected inside the limiting frame 314. A spring 316 is fixed inside the limiting frame 314, and one end of the spring 316 is fixedly connected to the magnet 315. A slot 318 is provided at the bottom of the magnet 315. A miniature electric push rod 319 is installed inside the slot 318, and a conical blade 320 is fixed at the output end of the electric push rod 319. A rodent-repelling structure 4 is provided inside the branch box 1.

[0023] The next step, the fire extinguishing structure 3, also includes a hollow box 321 fixed to the bottom of the material box 301. A push plate 322 is slidably connected inside the hollow box 321. The hollow box 321, located to the left of the push plate 322, is filled with vermiculite. A second support block 323 is fixed to the inner wall of the material box 301. A pointed rod 324 is slidably connected inside the second support block 323. One end of the pointed rod 324 is located inside the hollow box 321 and is fixedly connected to the push plate 322. The tip of the pointed rod 324 is located on one side of the plugging airbag 306. The part of the hollow box 321 filled with vermiculite is connected to a hollow tube 325. One end of the hollow tube 325 passes through the discharge box 301. A fine mesh is provided inside the hollow tube 325 to prevent vermiculite particles from flowing out of the hollow tube 325.

[0024] It should be noted that when the smoke sensor detects smoke inside the branch box 1 and the smoke reaches the spontaneous combustion threshold, it transmits a signal to the control system of the branch box 1. Then, the control system controls the motor 303 to rotate the hollow blade 311. When the hollow blade 311 rotates, it generates centrifugal force. Then, the first magnet 315 overcomes the elastic force of the first spring 316 and is thrown towards the tip of the hollow blade 311. The first spring 316 facilitates the reset of the first magnet 315. At the same time, the output end of the electric push rod 319 inside the first magnet 315 extends and brings out the blade 320. Since the path of the first magnet 315 is exactly on the path of the sealing airbag 313 when it moves by centrifugal force, the movement of the first magnet 315 will puncture the sealing airbag 313 through the blade 320, causing it to burst open. Then, the sprinkling port 312 can be opened. Meanwhile, the temperature of branch box 1, approaching the temperature required for the spontaneous combustion of vermiculite, reaches the temperature needed for its expansion. The vermiculite then expands within the hollow box 321, pushing the pusher plate 322 and the pointed rod 324 to move. As the pointed rod 324 moves, it punctures the blocking airbag 306, opening the discharge pipe 305. The dry powder accumulated in the material box 301 then enters the hollow disc 308 through the discharge pipe 305. When the hollow disc 308 rotates, the elastic vibrating plate 309 passes through the rigid rod 310 and undergoes deformation. The deformed elastic vibrating plate 309 then resets, generating a reciprocating motion. The reverberation and vibration, with the vibration generated by the reverberation, are transmitted to the interior of the hollow disc 308, which helps prevent dry powder from remaining inside the hollow disc 308. Then, the dry powder inside the hollow disc 308 enters the interior of the hollow blade 311, and under its rotation, it is discharged from the sprinkling port 312 and thrown into the interior of the branch box 1. The centrifugal force of the rotation of the hollow blade 311 makes the dry powder spread evenly, which can quickly cover a larger area inside the branch box 1. The dry powder thrown out at high speed mixes fully with the air to form a dust cloud, which enhances the contact reaction with the flame and accelerates the extinguishing.

[0025] Furthermore, the rodent-repelling structure 4 includes a first support rod 401 fixed to the inner wall of the branch box 1. The first support rod 401 is provided with a cylindrical groove 403. A second spring 404 and a top rod 405 are provided inside the cylindrical groove 403. The top rod 405 passes through the middle of the second spring 404. A circular pressure plate 406 is fixed to the outside of the top rod 405. The pressure plate 406 is slidably connected to the inner wall of the cylindrical groove 403. A second magnet 407 is fixed to one end of the top rod 405.

[0026] Exemplary, the rodent-repelling structure 4 also includes a second support rod 402 fixed to the inner wall of the branch box 1. A swingable bell 408 is installed at the bottom of the second support rod 402. One end of the top rod 405 contacts the bell 408. An elastic swing plate 409 is fixed to the bottom of the second support rod 402, located to one side of the bell 408. The bottom of the elastic swing plate 409 is located inside the wiring port 6. A colorful cat pattern is engraved on the bottom of the elastic swing plate 409. During heat dissipation, when the hollow blade 311 rotates, causing the first magnet 315 to overcome the elastic force of the first spring 316 and move towards the tip of the hollow blade 311, the first magnet 315 will move to the front of the second magnet 407. The first magnet 315 is a strong magnet and is of the same polarity as the second magnet 407. When magnet 315 comes to the front of magnet 407, the push rod 405 moves in the cylindrical groove 403 of support rod 401 due to the repulsion between like magnets. Then, pressure plate 406 presses spring 404, which helps push rod 405 return to its original position. When push rod 405 moves, it hits bell 408, which makes a sound to drive away mice. At the same time, bell 408 hits elastic swing plate 409, which then swings back and forth at connection port 6, scaring away mice that try to climb up through connection port 6. In addition, the cat pattern on the bottom of elastic swing plate 409 will make the mice see the cat and be frightened and driven away.

[0027] In addition, the branch box 1 is equipped with a cooling assembly 5, which is distributed inside and outside the branch box 1. The cooling assembly 5 includes a nozzle 501 on the top of the outer wall of the branch box 1 and a water collection tank 502 at the bottom. A filter screen 503 is installed on the top of the water collection tank 502. A water tank 504 is installed at the bottom of the branch box 1. The water tank 504 can be buried underground with a protective cover installed outside the water pump. The water pump is not shown in the figure. A water supply pipe 505 is installed. The water supply pipe 505 enters the interior of the branch box 1 from the connection port 6 and connects to the nozzle 501. A drain pipe 506 is connected to the bottom of the water collection tank 502, and the end of the drain pipe 506 is located inside the water tank 504. The water guide channel 507 is provided. The cooling component 5 and the hollow blades 311 form an internal and external cooling structure. The temperature sensor detects that the inside of the branch box 1 needs to be cooled, and then transmits the signal to the control system of the branch box 1. The control system then controls the water pump and motor 303 to start. The water pump is not shown in the figure. When the motor 303 starts, it drives the worm gear 304 to rotate. Then, under the action of the worm gear 307, it drives the discharge pipe 305 to rotate. The discharge pipe 305 plays the same role as the rotating shaft at this time. The rotation of the discharge pipe 305 drives the hollow disk 308 and the hollow blades 311 to rotate. The hollow blades 311, together with the heat dissipation holes, achieve air cooling heat dissipation inside the branch box 1. In addition, the water pump injects the cooling water in the water tank 504 into the nozzle 501 through the drain pipe 506. The water sprayed from the nozzle 501 moves along the water guide groove 507, so that the sprayed cooling water can fully contact the branch box 1 to achieve cooling and heat dissipation. The water guide groove 507 increases the contact area between the cooling water and the outer wall of the branch box 1, which further increases the cooling effect and achieves liquid cooling heat dissipation. At the same time, the water that falls is filtered by the filter screen 503 to remove impurities (the purpose is to prevent impurities on the outer wall of the branch box 1 from entering the drain pipe 506 and clogging the pipe). It is then collected back into the water tank 504 through the drain pipe 506, and then cooled down by the ground of the water tank 504 to form cooling water again. It is then pumped back into the nozzle 501 and collected again, which helps to realize the circulating cooling system.

[0028] It should be explained that a sprinkler head is installed at the top of the inner cavity of branch box 1, and the sprinkler head is connected to water tank 504 through a pipe (not shown in the figure).

[0029] Specifically, the water tank 504 at the bottom of branch box 1 is buried deep underground. Since the underground temperature is lower than the surface temperature, the soil can effectively absorb the heat of the water in the water tank 504, thereby naturally lowering the water temperature. At the same time, the insulation of the soil can also reduce the heat conduction of the water to the water from the outside high temperature, maintain the cooling effect of the water, and make the water tank 504 form cooling water. The water supply pipe 505 and the drain pipe 506 are hidden and cannot be seen from the ground. The water tank 504 is connected to a drain pipe, which is connected to the underground pipe network to facilitate the discharge of water in the water tank 504 after long-term circulation.

[0030] In addition, the branch box 1 is divided into indoor and outdoor types. When installed outdoors, rainwater enters the water collection tank 502 and then enters the water tank 504 through the drain pipe 506 to collect water. However, when the cable branch box 1 is installed indoors, water needs to be manually added to the water collection tank 502 and then enters the water tank 504 through the drain pipe 506. The water collection method is different because the installation location is different.

[0031] Furthermore, vermiculite exhibits high-temperature expansion characteristics; when heated, the evaporation of internal moisture leads to a significant increase in volume. The hollow tube 325 allows outside air (containing a certain amount of moisture) to enter the hollow box 321, providing the vermiculite with the necessary moisture source to fully expand under high-temperature conditions. Simultaneously, the hollow tube 325 also balances the internal and external air pressure, preventing excessive pressure on the hollow box 321 structure during vermiculite expansion and ensuring the stability and reliability of the fire extinguishing structure 3.

[0032] Working principle: The cooling components and temperature sensor detect the need for cooling inside branch box 1 and transmit the signal to the control system of branch box 1. The control system then starts the water pump and motor 303. When motor 303 starts, it drives the worm gear 304 to rotate, which in turn drives the discharge pipe 305 to rotate under the action of the worm gear 307. The discharge pipe 305 functions similarly to a rotating shaft, rotating the hollow disc 308 and hollow blades 311. The hollow blades 311, in conjunction with the heat dissipation holes, achieve air cooling of the interior of branch box 1. Simultaneously, the water pump injects the cooling water in the water tank 504 into the nozzle 501 through the drain pipe 506. The water sprayed from the nozzle 501 moves along the water guide groove 507, allowing the sprayed cooling water to fully contact the branch box 1 to achieve cooling and heat dissipation. The water guide groove 507 also increases the contact area between the cooling water and the outer wall of the branch box 1, further increasing the cooling effect and achieving liquid cooling heat dissipation. Meanwhile, the falling water is filtered by the filter screen 503 to remove impurities (the purpose is to prevent impurities on the outer wall of the branch box 1 from entering the drain pipe 506 and clogging the pipe). It is then collected back into the water tank 504 through the drain pipe 506, and then cooled down by the ground of the water tank 504 to form cooling water again. It is then pumped back into the nozzle 501 and collected again, which is beneficial for realizing a circulating cooling system. Through the fire extinguishing structure 3, when the smoke sensor detects smoke inside the branch box 1 and the smoke reaches the spontaneous combustion threshold, it transmits a signal to the control system of the branch box 1. The control system then controls the motor 303 to rotate the hollow blade 311. When the hollow blade 311 rotates, it generates centrifugal force. Then, the first magnet 315 overcomes the elastic force of the first spring 316 and is thrown towards the tip of the hollow blade 311. The first spring 316 facilitates the reset of the first magnet 315. At the same time, the output end of the electric push rod 319 inside the first magnet 315 extends, along with the blade 320. Since the path of the first magnet 315 is exactly on the path of the sealing airbag 313 when it moves due to centrifugal force, the movement of the first magnet 315 will puncture the sealing airbag 313 through the blade 320, causing it to burst open. Then, the sprinkling port 312 can be opened. Meanwhile, the branch box 1 reaches a near-self-ignition temperature, which is the temperature required for vermiculite expansion. The vermiculite then expands within the hollow box 321, pushing the pusher plate 322 and the pointed rod 324 to move. As the pointed rod 324 moves, it punctures the blocking airbag 306, opening the discharge pipe 305. The dry powder accumulated in the material box 301 then enters the hollow disc 308 through the discharge pipe 305. When the hollow disc 308 rotates, the elastic vibrating plate 309 passes through the rigid rod 310 and deforms. The deformed elastic vibrating plate 309 then resets, generating reciprocating oscillations and vibrations. These vibrations are transmitted to the interior of the hollow disc 308, helping to prevent dry powder from accumulating inside. The dry powder inside the hollow disc 308 then enters the hollow blade 311, and under its rotation, it is discharged from the spray port 312 and thrown into the branch box 1. The centrifugal force of the rotating hollow blade 311 makes the dry powder evenly dispersed, which can quickly cover a larger area inside the branch box 1. The high-speed dry powder mixes thoroughly with the air to form a dust cloud, which enhances the contact reaction with the flame and accelerates the extinguishing process. After all the dry powder is discharged, the water in the water tank 504 is pumped into the sprinkler head at the top of the inner cavity of the branch box 1 through the pipeline, and then the sprinkler head discharges the water to achieve secondary fire extinguishing. With the designed rodent-repellent component, during heat dissipation, the hollow blade 311 rotates, causing magnet 315 to overcome the elastic force of spring 316 and move towards the tip of the hollow blade 311. Magnet 315 then moves directly in front of magnet 407. Magnet 315 is a strong magnet and has the same polarity as magnet 407. Therefore, when magnet 315 reaches the front of magnet 407, the push rod 405 moves within the cylindrical groove 403 of support rod 401 due to the repulsive force between like magnets, and then presses down... Plate 406 compresses spring 404, which facilitates the reset of push rod 405. When push rod 405 moves, it strikes bell 408, causing it to ring and deter mice. Simultaneously, bell 408 strikes elastic swing plate 409, which then swings back and forth at connection port 6, scaring away mice attempting to climb through. Furthermore, the cat pattern on the bottom of elastic swing plate 409 clearly attracts the attention of mice, frightening them and driving them away. In summary, this system combines heat dissipation and mouse deterrence in a coordinated manner.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
