Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a distribution box with an automatic alarm function. Background Technology

[0002] Outdoor distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, lack of site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. Therefore, they are used in residential areas and various construction sites.

[0003] In existing distribution boxes, such as Chinese patent CN119695651B, when the sealing frame contacts the sealing ring, the sealing frame pushes the sealing ring to drive the rotating frame to rotate around the rotating shaft in the mounting ring groove. This prevents the part of the sealing ring in contact with the sealing frame from being excessively squeezed, thus preventing wear of the sealing ring. Furthermore, when the box door is fully closed, the rotating frame rotates to a position parallel to the box door, so that the rotating frame and the sealing frame together clamp the sealing ring to form a sealing structure around the mounting opening, thereby providing a safe and reliable sealing and waterproofing effect for the mounting opening.

[0004] However, the following problems still exist: outdoor distribution boxes are at high risk of physical damage. For example, small animals may enter through gaps and gnaw on cables, causing damage. External forces such as collisions caused by moving objects or accidental collisions by vehicles can also cause physical damage to outdoor distribution boxes, resulting in potential dangers such as short circuits in the internal wiring of the distribution box and electric shocks during distribution box maintenance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power distribution box with an automatic alarm function. This box effectively mitigates the physical risks posed by small and micro-sized animals to outdoor power distribution boxes, preventing them from entering and causing short circuits or electric shocks during maintenance.

[0016] Compared with the prior art, the present invention provides a distribution box with automatic alarm function, which has the following beneficial effects: 1. This power distribution box with automatic alarm function works by installing it in the desired location, filling the U-shaped extension trough with water until the water level is below the arc-shaped bottom of the trough's inner top wall, and then placing a ball on the tray. When small animals try to climb the power distribution box, their footing will pass over the rollers, forcing them to grip the rollers. The weight of the animals causes the rollers to rotate, thus obstructing their climb. Simultaneously, the rotating rollers emit air jets that startle the climbing animals. The rollers and jets work together to prevent small animals from climbing the box. When micro-animals invade the distribution box, they will enter the U-shaped extension channel. The water in the U-shaped extension channel will intercept micro-animals that do not enter the water. Animals that can wade through the water will be repelled by the scent emitted by the mothballs on the tray. By utilizing the pathway design of the U-shaped extension channel and the water and mothballs on the tray, the invasion of micro-animals into the box is prevented. This effectively addresses the risk of physical damage from small and micro-animals in outdoor distribution boxes, preventing them from causing short circuits in the internal wiring of the distribution box, electric shock during maintenance, and other problems, thereby improving the stability of the distribution box operation.

[0017] 2. This power distribution box with automatic alarm function, through the setting of the slide rail, ensures that the movement of the sliding sleeve on the sliding column is not affected by the movement of small animals in the water, thus ensuring the stability of the movement of the sliding sleeve and improving the accuracy of the water level buoy.

[0018] 3. The power distribution box with automatic alarm function seals the camphor balls in the storage pipe through the setting of a sealing door, so as to prevent the camphor balls from being used in the storage pipe and improve the stability of the use of the camphor balls in the storage pipe.

[0019] 4. This distribution box with automatic alarm function can alert maintenance personnel in real time when the external and internal protection mechanisms of the box work together to prevent intruding animals, ensuring that problems with the distribution box can be dealt with in a timely manner, thus ensuring the stability of the distribution box operation.

[0022] 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.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a distribution box with automatic alarm function.

[0024] Example 1, a typical implementation of this application, such as Figure 1As shown, a power distribution box with an automatic alarm function includes a box body 1, an external protection mechanism 2 installed on the box body 1, and an internal protection mechanism 3 installed inside the box body 1. The external protection mechanism 2 uses rollers 25 to obstruct the climbing footholds of small animals and uses nozzles 27 to spray air cannons to scare the climbing small animals, thereby preventing the small animals from climbing the box body 1. The internal protection mechanism 3 injects water into the U-shaped extension groove 31, leaving a gap between the water and the arc bottom of the inner top wall of the U-shaped extension groove 31. The U-shaped extension groove 31, together with the water, obstructs the route for micro animals to enter the box 1. Camphor balls placed on the feed tray 39 are used to drive away the micro animals, thereby preventing the micro animals from entering the box 1.

[0025] When using this invention: After installing the distribution box in the required location, water is poured into the U-shaped extension trough 31, leaving a gap between the water level and the arc bottom of the inner top wall of the U-shaped extension trough 31. Then, small animals are placed on the material tray 39. When small animals climb onto the distribution box, their footing will pass through the position of the roller 25, ensuring that the animal can only grip the roller 25. This causes the roller 25 to rotate under the weight of the small animal, thus obstructing its climbing. Simultaneously, after the roller 25 rotates, the nozzle 27 sprays air, startling the climbing small animals. The roller 25 and nozzle 27 work together to prevent small animals from climbing onto the box 1. When animals invade the distribution box, micro-animals will enter the U-shaped extension channel 31. The water in the U-shaped extension channel 31 will intercept micro-animals that do not enter the water. Animals that can wade through the water will be repelled by the scent emitted by the mothballs on the feed tray 39. In this way, the passage design of the U-shaped extension channel 31 and the water and the mothballs on the feed tray 39 can prevent micro-animals from invading into the box 1, thereby addressing the risk of physical harm from small and micro-animals in outdoor distribution boxes. This can effectively prevent small and micro-animals from entering the distribution box and causing problems such as short circuits in the internal wiring of the distribution box and electric shock during maintenance, thereby improving the stability of the distribution box operation.

[0026] Example 2, as Figures 2-5As shown, the difference from the above embodiment is that the external protection mechanism 2 includes an isolation ring 21. A cable port is provided at the bottom of the box body 1, and the cable port of the box body 1 extends to the outside of the box body 1. An isolation ring 21 is fitted on the cable port of the box body 1. The isolation ring 21 is divided into two parts that are symmetrically joined together and bolted together. The lower end of the isolation ring 21 extends to the bottom of the cable port of the box body 1. An inner connector 22 is provided at the bottom of the isolation ring 21. The outer wall of the top of the inner connector 22 is in contact with the inner wall of the bottom of the isolation ring 21. The inner connector 22 is divided into two parts that are symmetrically joined together and bolted together. A support column 23 is provided below the inner connector 22. The support column 23 is used to install the distribution box. The bottom end of the inner connector 22 extends into the support column 23, and the bottom end of the inner connector 22 is in contact with the support column 23.

[0027] Furthermore, multiple fixing frames 24 are fixedly installed on the isolation ring 21. The fixing frames 24 are evenly distributed in a circle and arranged in an array above and below. The fixing frames 24 are obliquely upward on the isolation ring 21. Each fixing frame 24 has a roller 25 rotatably fitted at its top. The diameter of the roller 25 is larger than the width of the fixing frame 24. Each fixing frame 24 has a detector 26 fixedly installed on it. The detection end of each detector 26 is connected to each roller 25.

[0028] Furthermore, the detector 26 detects that the rotation angle of the roller 25 needs to be greater than or equal to 180 degrees to avoid being affected by factors such as wind or gravity. When the roller 25 deflects slightly, it will also be determined that there is a small animal climbing.

[0029] Furthermore, multiple nozzles 27 are fixedly installed at the bottom of the housing 1. The nozzles 27 are evenly distributed in a circle and are located above the roller 25. The nozzles 27 face directly downwards. A ring tube 28 is fixedly installed at the bottom of the housing 1. The ring tube 28 is located above the cable port of the housing 1 and is connected to the nozzles 27. The connection between the ring tube 28 and the nozzles 27 passes through the housing 1, and the connection between the ring tube 28 and the nozzles 27 is sealed to the housing 1.

[0030] Furthermore, a solenoid valve 29 is fixedly installed at the bottom of the box 1, and the solenoid valve 29 is connected to the ring pipe 28. An air storage tank 210 is fixedly installed at the bottom of the box 1, and the air storage tank 210 is connected to the solenoid valve 29. An air pump 211 is fixedly installed at the bottom of the box 1, and the exhaust end of the air pump 211 is connected to the air storage tank 210. A filter head 212 is fixedly installed on the air inlet end of the air pump 211, and the filter head 212 is connected to the air pump 211.

[0031] When preventing small animals from intruding, the small animals will first climb up the pillar 23, and after passing the inner connector 22, they will climb onto the isolation ring 21. At this time, the footholds of the small animals on the isolation ring 21 are all covered by the rollers 25 on the fixing frame 24, so that when the small animals land on the isolation ring 21, they will grab onto the rollers 25. Using their own weight, when the small animals grab onto the rollers 25, the rollers 25 will rotate, causing the small animals to lose their climbing and gripping positions, thus hindering the small animals. At the same time, the detector 26 detects that the rotation angle of the rollers 25 is greater than or equal to 180 degrees, and the detector... 26 controls the solenoid valve 29 to open, releasing compressed air from the air tank 210 into the ring pipe 28, and then into the nozzle 27. The nozzle 27 sprays compressed air to form an air cannon that shoots at small animals climbing below, thus startling them. The loss of their climbing grip and the startling effect of the air cannon work together to prevent the small animals from climbing. Detector 26 also controls the alarm 314 to sound an alarm, reminding maintenance personnel to check. Meanwhile, the air pump 211 is started, and the air is filtered through the filter head 212 to compress the air into the air tank 210 for storage.

[0032] Example 3, as Figures 6-12 As shown, the difference from the above embodiment is that the internal protection mechanism 3 includes a slide rail 32, multiple ventilation openings are provided on both sides of the box body 1, and multiple U-shaped extension grooves 31 are fixedly installed on both sides of the box body 1. Each U-shaped extension groove 31 is connected to each ventilation opening of the box body 1. The size of the connection between the U-shaped extension groove 31 and the ventilation opening of the box body 1 is adapted to the size of the ventilation opening of the box body 1. A slide rail 32 is fixedly installed on the inner side wall of each U-shaped extension groove 31. The slide rail 32 is located at the bottom end of the U-shaped structure inside the U-shaped extension groove 31, and the length of the slide rail 32 is adapted to the height of the bottom end of the U-shaped structure inside the U-shaped extension groove 31.

[0033] Furthermore, each slide rail 32 is fixedly installed with a slide column 33. The length of the slide column 33 is adapted to the height of the slide rail 32. Each slide column 33 is fitted with a slide sleeve 34. The slide sleeve 34 slides in cooperation with the slide column 33. Each slide sleeve 34 is fixedly installed with a water level float 35. The water level float 35 extends into the U-shaped extension groove 31. The water level float 35 is used to detect the water level height.

[0034] Furthermore, a switch rod 36 is fixedly installed on each of the sliding sleeves 34. The switch rod 36 is located inside the slide rail 32. A micro switch 37 is fixedly installed on the top of the inner side wall of the slide rail 32. The micro switch 37 is located on the moving trajectory of the switch rod 36. A controller 38 is fixedly installed on the outside of the U-shaped extension groove 31. Each controller 38 is connected to each micro switch 37 via signal.

[0035] Furthermore, both ends of the U-shaped extension groove 31 are open ends. One open end of the U-shaped extension groove 31 is connected to the ventilation opening of the box 1. A material tray 39 is fixedly installed on the other end of the U-shaped extension groove 31. The material tray 39 is located at the center of the other end of the U-shaped extension groove 31. The material tray 39 is used to place the brain pills. A discharge conduit 310 is fixedly installed on the material tray 39. The bottom end of each discharge conduit 310 faces the material tray 39. An electric control valve 311 is fixedly installed at the top end of each discharge conduit 310. The electric control valve 311 is connected to the discharge conduit 310. A storage pipe 312 is fixedly installed on each electric control valve 311. The storage pipe 312 is connected to the electric control valve 311. A sealing door 313 is rotatably fitted at the top end of each storage pipe 312. The sealing door 313 is used to seal and cover the storage pipe 312.

[0036] Furthermore, an alarm 314 is fixedly installed at the top of the enclosure 1. The controller 38 is connected to the alarm 314 via signal, and the detector 26 is connected to the alarm 314 via signal. The alarm 314 will sound an alarm after receiving a signal.

[0037] Furthermore, the alarm 314 can be connected to maintenance personnel's computers or mobile phones, which can alert maintenance personnel to check when an alarm is triggered.

[0038] When preventing the intrusion of micro-animals, they enter through the ventilation opening of the housing 1 and then into the U-shaped extension groove 31. Micro-animals such as ants are blocked by the water in the U-shaped extension groove 31. For micro-animals capable of wading, the water level rises after entering the water, causing the water level float 35 to rise accordingly. The water level float 35 moves the sliding sleeve 34 on the sliding column 33, which in turn moves the switch rod 36 upwards, triggering the micro switch 37. The controller 38 receives the signal generated by the micro switch 37. The controller 38 activates the alarm 314 to sound an alarm. At the same time, the mothballs on the feed tray 39 emit an odor that deters small animals from crossing the water, causing them to turn back and leave the box 1. After the mothballs on the feed tray 39 are used up, the electric control valve 311 is activated. The electric control valve 311 opens, allowing the spare mothballs in the storage pipe 312 to pass through the electric control valve 311 and enter the discharge pipe 310. The discharge pipe 310 drops the mothballs onto the feed tray 39, and maintenance personnel can open the sealing door 313 to replenish the mothballs in the storage pipe 312.

[0039] Working principle of the invention: After installing the distribution box in the required location, water is poured into the U-shaped extension trough 31, leaving a gap between the water level and the arc bottom of the inner top wall of the U-shaped extension trough 31. Then, small animals are placed on the material tray 39. When small animals climb onto the distribution box, their footing will pass through the position of the roller 25, ensuring that the animal can only grip the roller 25. This causes the roller 25 to rotate under the weight of the small animal, thus obstructing its climbing. Simultaneously, after the roller 25 rotates, the nozzle 27 sprays air, startling the climbing small animals. The roller 25 and nozzle 27 work together to prevent small animals from climbing onto the box 1. When animals invade the distribution box, micro-animals will enter the U-shaped extension channel 31. The water in the U-shaped extension channel 31 will intercept micro-animals that do not enter the water. Animals that can wade through the water will be repelled by the scent emitted by the mothballs on the tray 39. In this way, the passage design of the U-shaped extension channel 31 and the water and the mothballs on the tray 39 will prevent micro-animals from invading into the box 1. This will effectively prevent small and micro-animals from entering the distribution box and causing problems such as short circuits in the internal wiring of the distribution box and electric shock during maintenance. This will improve the stability of the distribution box operation. When preventing small animals from intruding, the small animals will first climb up the pillar 23, and after passing the inner connector 22, they will climb onto the isolation ring 21. At this time, the footholds of the small animals on the isolation ring 21 are all covered by the rollers 25 on the fixing frame 24, so that when the small animals land on the isolation ring 21, they will grab onto the rollers 25. Using their own weight, when the small animals grab onto the rollers 25, the rollers 25 will rotate, causing the small animals to lose their climbing and gripping positions, thus hindering the small animals. At the same time, the detector 26 detects that the rotation angle of the rollers 25 is greater than or equal to 180 degrees, and the detector... 26 controls the solenoid valve 29 to open, releasing compressed air from the air tank 210 into the ring pipe 28, and then into the nozzle 27. The nozzle 27 sprays compressed air to form an air cannon that shoots at the small animals climbing below, thus startling them. The loss of their climbing grip and the startling effect of the air cannon work together to prevent the small animals from climbing. In addition, the detector 26 also controls the alarm 314 to sound an alarm, reminding maintenance personnel to check. The air pump 211 is started, and the air is filtered through the filter head 212 to compress the air into the air tank 210 for storage. When preventing the intrusion of micro-animals, they enter through the ventilation opening of the housing 1 and then into the U-shaped extension groove 31. Micro-animals such as ants are blocked by the water in the U-shaped extension groove 31. For micro-animals capable of wading, the water level rises after entering the water, causing the water level float 35 to rise accordingly. The water level float 35 moves the sliding sleeve 34 on the sliding column 33, which in turn moves the switch rod 36 upwards, triggering the micro switch 37. The controller 38 receives the signal generated by the micro switch 37, causing... The controller 38 activates the alarm 314 to sound an alarm. At the same time, the mothballs on the feed tray 39 emit an odor that deters micro-animals from crossing the water, causing them to turn back and leave the box 1. After the mothballs on the feed tray 39 are used up, the electric control valve 311 is activated. The electric control valve 311 opens, allowing the spare mothballs in the storage pipe 312 to pass through the electric control valve 311 and enter the discharge pipe 310. The discharge pipe 310 drops the mothballs onto the feed tray 39, and maintenance personnel can open the sealing door 313 to replenish the mothballs in the storage pipe 312.
