Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution cabinet technology, specifically to an open-air power distribution cabinet with protective functions based on urban power supply. Background Technology
[0002] Outdoor power distribution cabinets are often targeted for theft, affecting nighttime lighting and road traffic safety, causing economic losses to municipalities. Traditional power distribution cabinets mostly use locks for theft prevention, which have limited protective performance.
[0003] Patent CN111697445B relates to an open-air distribution cabinet with protective functions for urban power supply, belonging to the field of distribution cabinet technology. It addresses the problem that existing outdoor distribution cabinets, which mostly use locks for security, offer only limited protection and cannot effectively reduce the probability of theft. The proposed open-air distribution cabinet with protective functions for urban power supply includes a cabinet with a simulated flip-top door embedded in its front end. A rainproof and heat dissipation mechanism is fixedly installed on the top of the cabinet. The simulated flip-top door resembles a traditional flip-top door, so when equipment such as copper busbars inside the cabinet is stolen, it will identify the simulated flip-top door as the actual flip-top door. However, this device does not alert passersby during theft, potentially allowing thieves to continue their theft. Therefore, this open-air distribution cabinet with protective functions for urban power supply solves the aforementioned problems. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an open-air power distribution cabinet with protective function based on urban power supply, which addresses the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an open-air distribution cabinet with protective function based on urban power supply, including a shell, a base fixedly connected to the bottom of the shell, a schematic door rotatably connected to the front of the shell, a ventilation window fixedly connected to the inner wall of the shell, a mounting bracket fixedly connected to the inner wall of the shell, a rear door rotatably connected to the rear of the shell, a sliding rod slidably connected to the inner wall of the shell by a spring, a movable door rotatably connected to the inner wall of the base, a fixed rod fixedly connected to the inner wall of the sliding rod, and a pedal fixedly connected to the circumferential surface of the fixed rod. A U-shaped plate is fixedly connected to the inner wall of the first door, and a straight rod is fixedly connected to the inner wall of the U-shaped plate. A connecting block is fixedly connected to the front of the rear door. An alarm detector is fixedly connected to the inner wall of the outer shell. A connecting plate is rotatably connected to the rear of the indicator door, and a straight rod is rotatably connected to the inner wall of the connecting plate. A limit plate is fixedly connected to the inner wall of the outer shell. A cooling mechanism for improving ventilation is provided on the inner wall of the outer shell. A fireproof mechanism for preventing fires is provided on the inner wall of the outer shell. A trigger is fixedly connected to the top of the limit plate. When it is necessary to inspect the interior of the outer shell, the rear door can be opened for inspection. By concealing the "real" cabinet door on the outer shell, when a thief intends to steal the electronic components and brass materials inside the shell, the thief will damage the keyhole used to deceive the indicator door. The thief will then find that the indicator door can only be opened a short distance, thus preventing them from stealing the electronic components inside and causing them to give up. This effectively protects the electronic components and avoids impacting the city's power supply. The inner wall of the base is slidably connected to the circumferential surface of the sliding rod one, the circumferential surface of the straight rod one is in contact with the inner wall of the connecting block, the trigger is electrically connected to the alarm detector, and the inner wall of the limiting plate slides with the circumferential surface of the straight rod two. The alarm detector is connected to the enclosure to detect the internal temperature and trigger an alarm. When a thief opens the signal door, the signal door rotates and pulls the connecting plate, which in turn moves the straight rod. During this movement, the straight rod contacts the trigger and squeezes it, generating an electrical signal. This signal is then transmitted to the alarm detector via a data cable, triggering an alarm. This alerts nearby personnel or the monitoring center to take swift action to prevent further damage to equipment or property. It also reminds them that the distribution cabinet is monitored and protected, helping to reduce theft.
[0006] Preferably, the cooling mechanism includes a chamfered block, which is fixedly connected to the inner wall of the outer casing. A second sliding rod is slidably connected to the inner wall of the outer casing via a spring. A fixing plate is fixedly connected to the circumferential surface of the first straight rod. An insert rod is fixedly connected to the inner wall of the fixing plate. A threaded rod is rotatably connected to the inner wall of the mounting bracket. A push plate is threadedly connected to the circumferential surface of the threaded rod. A perforated plate is fixedly connected to the inner wall of the outer casing. A sliding block is slidably connected to the inner wall of the perforated plate. A brush plate is fixedly connected to the inner wall of the sliding block. A hinge rod is rotatably connected to the inner wall of the sliding block. A second fixing rod is fixedly connected to the inner wall of the mounting bracket via a spring. A movable plate is slidably connected to the circumferential surface of the second fixing rod. This design allows for normal maintenance of internal electronic components during inspection of the outer casing, preventing issues such as the back door becoming stuck. The design allows for easy opening of the door, while also improving its concealment and reducing the probability of being discovered by thieves. This further enhances the protection of electronic components. The circumferential surface of the insertion rod contacts the inner wall of the sliding rod. A motor is located on the right side of the push plate, driving the push plate to rotate. The left side of the ventilation window contacts the right side of the brush plate. The surface of the mounting bracket is slidably connected to the inner wall of the push plate. The inner wall of the hinge rod is rotatably connected to the circumferential surface of the movable plate. When the internal temperature of the housing is too high, dust and impurities accumulated inside the ventilation window can be hung down, reducing dust damage to internal components and improving the reliability and stability of the equipment. At the same time, it can increase the air circulation rate inside the housing, ensuring good ventilation and heat dissipation, and guaranteeing that the equipment operates within a suitable temperature range.
[0007] Preferably, the fire-prevention mechanism includes a dry powder box, which is fixedly connected to the inner wall of the outer shell. An opening and closing plate is rotatably connected to the inner wall of the dry powder box. A rounded corner plate is fixedly connected to the bottom of the dry powder box. An elastic rod is slidably connected to the inner wall of the rounded corner plate via a spring. A shaped plate is fixedly connected to the circumferential surface of the elastic rod. A sliding rod three is slidably connected to the inner wall of the dry powder box. A stirring frame is fixedly connected to the circumferential surface of the sliding rod three. An arc-shaped plate is fixedly connected to the circumferential surface of the sliding rod three. When the internal temperature of the outer shell is abnormally high and a fire may occur, the dry powder inside the dry powder box can be poured out, and the dry powder can extinguish any hidden flames inside the outer shell. This rapid response can minimize equipment damage and prevent the fire from spreading to other parts of the shell. To ensure the normal operation of the city's power supply system and to guarantee timely protection of equipment in case of failure, thereby improving overall safety, the dry powder box is used to store dry powder for fire extinguishing. The top of the opening and closing plate is in contact with the bottom of the stirring frame. The movable plate will contact the arc-shaped plate during operation, and the bottom of the opening and closing plate will contact the top of the irregular plate. During cooling and heat dissipation, the dry powder inside the dry powder box can be turned over to prevent the dry powder from clumping due to moisture, temperature changes, or other factors, which would greatly reduce the fire extinguishing effect. By turning the dry powder, its looseness can be maintained, ensuring that the dry powder can be quickly and evenly spread and effectively extinguish the fire source in the event of a fire, thereby improving the overall fire extinguishing capability of the system.
[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This type of open-air distribution cabinet with protective functions for urban power supply, through the coordinated operation of the outer shell, base, indicator door, ventilation window, mounting bracket, rear door, movable door, sliding rod one, fixed rod one, pedal, U-shaped plate, straight rod one, connecting block, alarm detector, connecting plate, straight rod two, limit plate, and trigger, allows for inspection of the interior of the outer shell by opening the rear door. By concealing the "real" cabinet door, if a thief intends to steal electronic components and brass materials from the inner wall of the outer shell, the thief will damage the keyhole of the indicator door, which will then only open a short distance, preventing further inspection. The system effectively protects the electronic components inside the casing from theft, preventing disruption to the city's power supply. When a thief opens the signal door, it rotates and pulls a connecting plate, which in turn moves a straight rod. During this movement, the straight rod contacts and presses the trigger, generating an electrical signal. This signal is then transmitted via a data cable to the alarm detector, triggering an alarm and alerting nearby personnel or the monitoring center to take swift action to prevent further damage to equipment or property. The system also alerts them that the distribution cabinet is monitored and protected, helping to reduce theft.
[0009] 2. This type of open-air distribution cabinet with protective function based on urban power supply, through the coordinated operation of chamfered blocks, sliding rod 2, fixing plate and plug rod, allows staff to inspect the internal electronic components while inspecting the outer shell, avoiding the situation where the back door is jammed and cannot be opened. At the same time, it can improve the concealment of the back door to a certain extent, reduce the probability of being discovered by thieves, and further improve the protection of electronic components.
[0010] 3. This type of open-air distribution cabinet with protective function based on urban power supply, through the coordinated operation of threaded rods, push plates, hollow plates, sliding blocks, brush plates, hinge rods, fixed rods, and movable plates, can remove dust and impurities accumulated inside the ventilation windows when the internal temperature of the outer shell is too high. This can reduce the damage of dust to internal components, improve the reliability and stability of the equipment, and at the same time improve the air circulation rate inside the outer shell, ensuring good ventilation and heat dissipation, and ensuring that the equipment operates within a suitable temperature range.
[0011] 4. This type of open-air distribution cabinet with protective functions based on urban power supply, through the coordinated operation of dry powder box, opening and closing plate, rounded corner plate, elastic rod, and irregular plate, can pour out the dry powder inside the dry powder box when the internal temperature of the outer shell is abnormally high and may cause a fire, and extinguish the hidden flames inside the outer shell with the dry powder. This rapid response can minimize equipment damage, prevent the fire from spreading to other areas or affecting the normal operation of the urban power supply system, ensure that the equipment is protected in time when a fault occurs, and improve overall safety.
[0012] 5. This type of open-air distribution cabinet with protective function based on urban power supply, through the coordinated operation of sliding rod three, stirring frame and arc plate, can turn over the dry powder inside the dry powder box during the cooling and heat dissipation work, to prevent the dry powder from clumping due to moisture, temperature changes or other factors, which would greatly reduce the fire extinguishing effect. By turning over the dry powder, its looseness can be maintained, ensuring that the dry powder can be quickly and evenly spread and effectively extinguish the fire source in the event of a fire, thereby improving the overall fire extinguishing capability of the system.

[0015] 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.
[0016] Please see Figures 1-9One embodiment of the present invention is: an open-air distribution cabinet with protective function based on urban power supply, including a shell 1, a base 2 fixedly connected to the bottom of the shell 1, a schematic door 3 rotatably connected to the front of the shell 1, a ventilation window 4 fixedly connected to the inner wall of the shell 1, a mounting bracket 5 fixedly connected to the inner wall of the shell 1, a rear door 6 rotatably connected to the rear of the shell 1, a sliding rod 8 slidably connected to the inner wall of the shell 1 by a spring, a movable door 7 rotatably connected to the inner wall of the base 2, a fixed rod 9 fixedly connected to the inner wall of the sliding rod 8, and a pedal 10 fixedly connected to the circumferential surface of the fixed rod 9. A U-shaped plate 11 is fixedly connected to the inner wall of rod 8. A straight rod 12 is fixedly connected to the inner wall of U-shaped plate 11. A connecting block 13 is fixedly connected to the front of the rear door 6. An alarm detector 14 is fixedly connected to the inner wall of the outer shell 1. A connecting plate 15 is rotatably connected to the rear of the schematic door 3. A straight rod 16 is rotatably connected to the inner wall of the connecting plate 15. A limit plate 17 is fixedly connected to the inner wall of the outer shell 1. A cooling mechanism 18 for improving ventilation is provided on the inner wall of the outer shell 1. A fireproof mechanism 19 for preventing fire is provided on the inner wall of the outer shell 1. A trigger 20 is fixedly connected to the top of the limit plate 17. When it is necessary to inspect the inside of the outer casing 1, the staff opens the hidden movable door 7 and presses down the pedal 10. The downward movement of the pedal 10 will cause the sliding rod 8 to move downward, which in turn will cause the U-shaped plate 11 to move downward. The downward movement of the U-shaped plate 11 will cause the straight rod 12 to move downward, which will move away from the inner wall of the connecting block 13. At this time, the limit of the back door 6 can be released, and the back door 6 can be opened for inspection. By hiding the "real" cabinet door of the outer casing 1, when a thief intends to steal the electronic components and brass materials inside the outer casing 1, the thief will damage the keyhole of the deceptive door 3. Then, they will find that the deceptive door 3 can only be opened a short distance, and thus they will be unable to steal the electronic components inside the outer casing 1 and will give up. This can effectively protect the electronic components and avoid affecting the city's power supply. The inner wall of the base 2 is slidably connected to the circumferential surface of the sliding rod 8, the circumferential surface of the straight rod 12 is in contact with the inner wall of the connecting block 13, the trigger 20 is electrically connected to the alarm detector 14, the inner wall of the limit plate 17 is slidably connected to the circumferential surface of the straight rod 16, and the alarm detector 14 will be used to detect the temperature inside the housing 1 and issue an alarm. When the thief opens the signal door 3, the signal door 3 will rotate and pull the connecting plate 15 to move. The movement of the connecting plate 15 will pull the straight rod 16 to move. During the movement, the straight rod 16 will come into contact with the trigger 20 and squeeze the trigger 20, causing it to generate an electrical signal. The electrical signal will then be transmitted to the alarm detector 14 through the data line, thereby triggering an alarm. This can alert nearby personnel or the monitoring center, allowing them to take quick measures to prevent further damage to equipment or property. It also reminds them that the power distribution cabinet has been monitored and protected, which helps to reduce the occurrence of theft.
[0017] Working principle: When it is necessary to inspect the inside of the outer casing 1, the staff opens the hidden movable door 7 and presses down the pedal 10. The downward movement of the pedal 10 will drive the sliding rod 8 to move downward. By concealing the "real" cabinet door of the outer casing 1, if a thief intends to steal electronic components and brass materials from the inner wall of the outer casing 1, the thief will damage the lock hole of the deceptive indicator door 3. Subsequently, it will be found that the indicator door 3 can only be opened a short distance. When the thief opens the indicator door 3, the indicator door 3 will rotate and pull the connecting plate 15 to move. The movement of the connecting plate 15 will pull the straight rod 16 to move. During the movement, the straight rod 16 will come into contact with the trigger 20 and squeeze the trigger 20, which can alert nearby personnel or the monitoring center, prevent further damage to equipment or property, and help reduce the occurrence of theft.
[0018] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the cooling mechanism 18 includes a chamfered block 181, which is fixedly connected to the inner wall of the outer shell 1. The inner wall of the outer shell 1 is slidably connected to a sliding rod 182 via a spring. A fixing plate 183 is fixedly connected to the circumferential surface of the straight rod 12. An insert rod 184 is fixedly connected to the inner wall of the fixing plate 183. A threaded rod 185 is rotatably connected to the inner wall of the mounting frame 5. A push plate 186 is threadedly connected to the circumferential surface of the threaded rod 185. A hollow plate 187 is fixedly connected to the inner wall of the outer shell 1. A sliding block 188 is slidably connected to the inner wall of the hollow plate 187. A brush plate 189 is fixedly connected to the inner wall of the sliding block 188. A hinge rod 1810 is rotatably connected to the inner wall of the sliding block 188. A fixing rod 1811 is fixedly connected to the inner wall of the mounting frame 5 via a spring. A movable plate 1812 is slidably connected to the circumferential surface of the fixing rod 1811. When the staff inspects the outer casing 1, the downward movement of the straight rod 12 will cause the fixing plate 183 to move downward. The downward movement of the fixing plate 183 will cause the insertion rod 184 to move downward. The downward movement of the insertion rod 184 will leave the interior of the sliding rod 182. At this time, the sliding rod 182 can be released from its limit and move backward through the spring. At this time, the sliding rod 182 will contact the rear door 6 and push the rear door 6 outward, so that the staff can normally inspect the internal electronic components and avoid the situation where the rear door 6 is stuck and cannot be opened. By reducing the design of the installation handle, the concealment of the rear door 6 can be improved to a certain extent, reducing the probability of being discovered by thieves, and further improving the protection of electronic components.
[0019] The circumferential surface of the insertion rod 184 is in contact with the inner wall of the sliding rod 182. A motor is provided on the right side of the push plate 186, and the push plate 186 will be driven by the motor to rotate. The left side of the ventilation window 4 is in contact with the right side of the brush plate 189. The surface of the mounting bracket 5 is slidably connected to the inner wall of the push plate 186. The inner wall of the hinge rod 1810 is rotatably connected to the circumferential surface of the movable plate 1812. When the internal temperature of the outer casing 1 is too high, the motor starts and drives the threaded rod 185 to rotate. The rotation of the threaded rod 185 passes through the threaded groove on its surface, allowing the push plate 186 to move according to the direction of the motor rotation. During the movement of the push plate 186, it comes into contact with the movable plate 1812, pushing the movable plate 1812 to the right and compressing the spring on the surface of the fixed rod 1811. The spring can push the movable plate 1812 to reset. The movement of the movable plate 1812 will squeeze the hinge rod 1810, allowing the hinge rod 1810 to move to the right. The movement of the hinge rod 1810 will exert a downward squeezing force on the sliding block 188, forcing the sliding block 188 to move downward. The downward movement of the sliding block 188 will drive the brush plate 189 to move downward, thereby removing the dust and impurities accumulated inside the ventilation window 4. This can reduce the damage of dust to internal components, improve the reliability and stability of the equipment, and at the same time improve the air circulation rate inside the outer casing 1, ensuring good ventilation and heat dissipation, and ensuring that the equipment operates within a suitable temperature range.
[0020] Working principle: When the staff inspects the outer casing 1, the downward movement of the straight rod 12 will cause the fixing plate 183 to move downward. The downward movement of the fixing plate 183 will cause the insert rod 184 to move downward. The downward movement of the insert rod 184 will disengage from the interior of the sliding rod 182. At this time, the sliding rod 182 will contact the rear door 6 and push the rear door 6 outward, preventing the rear door 6 from getting stuck and unable to be opened. At the same time, it can improve the concealment of the rear door 6 to a certain extent, reduce the probability of being discovered by thieves, and further improve the protection of electronic components. For protection, when the internal temperature of the outer casing 1 is too high, the motor will start and drive the threaded rod 185 to rotate. The spring can push the movable plate 1812 to reset. The movement of the movable plate 1812 will squeeze the hinge rod 1810. The movement of the hinge rod 1810 will generate a downward squeezing force on the sliding block 188, forcing the sliding block 188 to move downward. The downward movement of the sliding block 188 will drive the brush plate 189 to move downward, thereby hanging down the dust and impurities accumulated inside the ventilation window 4, which can reduce the damage of dust to the internal components.
[0021] The fireproof mechanism 19 includes a dry powder box 191, which is fixedly connected to the inner wall of the outer shell 1. An opening and closing plate 192 is rotatably connected to the inner wall of the dry powder box 191. A rounded corner plate 193 is fixedly connected to the bottom of the dry powder box 191. An elastic rod 194 is slidably connected to the inner wall of the rounded corner plate 193 by a spring. A shaped plate 195 is fixedly connected to the circumferential surface of the elastic rod 194. A sliding rod 196 is slidably connected to the inner wall of the dry powder box 191. An agitator 197 is fixedly connected to the circumferential surface of the sliding rod 196. An arc-shaped plate 198 is fixedly connected to the circumferential surface of the sliding rod 196. When the internal temperature of the outer casing 1 is abnormally high and may cause a fire, the alarm detector 14 will detect the fire and transmit an electrical signal to the motor on the right side of the push plate 186, which will extend the time for the threaded rod 185 to rotate forward, thereby extending the leftward movement distance of the push plate 186. At this time, the movable plate 1812 can contact the irregular plate 195 and push the irregular plate 195 to move to the left. The leftward movement of the irregular plate 195 will drive the elastic rod 194 to move to the left, thereby releasing the limit on the opening and closing plate 192, allowing the opening and closing plate 192 to open, so that the dry powder inside the dry powder box 191 can be poured out and used to extinguish the hidden flames inside the outer casing 1. This rapid response can minimize equipment damage, prevent the fire from spreading to other areas or affecting the normal operation of the city's power supply system, ensure that the equipment is protected in time when a failure occurs, and improve overall safety. The dry powder box 191 will be used to store dry powder for fire extinguishing. The top of the opening and closing plate 192 is in contact with the bottom of the stirring frame 197. The movable plate 1812 will contact the arc plate 198 during operation. The bottom of the opening and closing plate 192 is in contact with the top of the irregular plate 195. During the cooling and heat dissipation process, the movable plate 1812 will contact the arc-shaped plate 198 and exert an upward compressive force on the arc-shaped plate 198, allowing it to move upward. The upward movement of the arc-shaped plate 198 will drive the sliding rod 196 to move upward, which in turn will drive the stirring frame 197 to move upward. When the stirring frame 197 moves, it can agitate the dry powder inside the dry powder box 191, preventing the dry powder from clumping due to moisture, temperature changes, or other factors, which would greatly reduce the fire extinguishing effect. By agitating the dry powder, its looseness can be maintained, ensuring that in the event of a fire, the dry powder can be quickly and evenly spread and effectively extinguish the fire source, thereby improving the overall fire extinguishing capability of the system.
[0022] Working principle: When the internal temperature of the outer casing 1 is abnormally high and may cause a fire, the alarm detector 14 will detect it and transmit an electrical signal to the motor on the right side of the push plate 186, which will extend the forward rotation time of the threaded rod 185, thereby extending the leftward movement distance of the push plate 186. At this time, the movable plate 1812 can contact the irregular plate 195 and push the irregular plate 195 to the left. The dry powder will extinguish the hidden flames inside the outer casing 1. This rapid response can minimize equipment damage. When cooling and heat dissipation, the movable plate 1812 will contact the arc plate 198 and apply an upward squeezing force to the arc plate 198, so that the arc plate 198 can move upward. When the stirring frame 197 moves, it can turn over the dry powder inside the dry powder box 191 to prevent the dry powder from clumping due to moisture, temperature changes or other factors, which would greatly reduce the fire extinguishing effect.
