Description

Technical Field

[0001] This invention relates to the field of distribution cabinet technology, specifically a safety distribution cabinet for power engineering. Background Technology

[0002] Safety-type distribution cabinets for power engineering mainly involve the design and functional optimization of distribution cabinets in power equipment. Based on traditional distribution cabinets, adding warning functions can help monitor the working status of electrical equipment in a timely manner, prevent potential safety hazards, and ensure the reliable operation of the power system.

[0003] Patent CN219498607U discloses a power distribution cabinet with a warning function. The cabinet has a door assembly at its front end, a door lock assembly on one side, and includes a mounting groove integrated into the front edge of the cabinet body. It also includes an arc-shaped top located inside the mounting groove, with a top connecting seat bonded to the lower end of the arc-shaped top. A compression spring is located at the lower end of the top connecting seat, and a gravity sensor is located at the lower end of the compression spring. This patent addresses the problem of existing power distribution cabinets lacking warning effects when the door is opened, and the risk of damage to the cabinet's interior due to unauthorized opening, leading to poor safety.

[0004] However, the aforementioned devices are difficult to comprehensively warn the surrounding crowd during use, resulting in blind spots in the warning and affecting the warning effect. Therefore, a safety distribution cabinet for power engineering is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a safety distribution cabinet for power engineering, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a safety distribution cabinet for power engineering, including a cabinet body, an opening and closing door rotatably connected to the inner wall of the cabinet body, a motor fixedly connected to the inner wall of the cabinet body, a reciprocating lead screw fixedly connected to the output end of the motor, a limit post fixedly connected to the inner wall of the cabinet body, a long plate movably connected to the circumferential surface of the reciprocating lead screw, a connecting block fixedly connected to the top of the long plate, a pushing block fixedly connected to the top of the connecting block, a hinge plate one rotatably connected to the inner wall of the cabinet body via a torsion spring, a night warning sign fixedly connected to the inner wall of the hinge plate one, an elastic telescopic rod fixedly connected to the inner wall of the cabinet body, a connecting plate fixedly connected to the telescopic end of the elastic telescopic rod, a wedge block one fixedly connected to the left side of the connecting plate, and a second hinge plate two rotatably connected to the inner wall of the cabinet body via a torsion spring. A lamp post is fixedly connected to the inner wall of the inclined block one, an L-shaped rod is fixedly connected to the bottom of the long plate, and a protrusion is fixedly connected to the right side of the L-shaped rod. A warning mechanism for maintenance is provided on the inner wall of the distribution cabinet, and a cleaning mechanism for dust removal is provided on the left side of the distribution cabinet. The long plate is slidably connected to the circumferential surface of the limiting post. The inclined block one contacts the distribution cabinet, and the connecting plate contacts the distribution cabinet, enabling the nighttime warning sign to alert surrounding people, reminding them that maintenance is underway in the area, and keeping unrelated personnel away, thus improving the safety of the device. The lamp post appears within the line of sight of people, increasing the warning effect of the device and preventing blind spots in the view of the nighttime warning sign caused by different positions, thus avoiding the failure to observe the lamp post. The movement of the lamp post further enhances the warning effect of the device and improves its efficiency.

[0007] Preferably, the warning mechanism includes a hollow block, a fixing plate, a connecting column, and a striking block. The hollow block is fixedly connected to the inner wall of the distribution cabinet. The fixing plate is fixedly connected to the left side of the night warning sign. The connecting column is fixedly connected to the bottom of the fixing plate. The striking block is fixedly connected to the bottom of the connecting column. The warning mechanism also includes a first connecting column, a fixing rod, a push block, and a protective cover. The first connecting column is fixedly connected to the inner wall of the protrusion. The fixing rod is fixedly connected to the circumferential surface of the first connecting column. The push block is fixedly connected to the top of the fixing rod. The protective cover is slidably connected to the inner wall of the distribution cabinet. When the striking block contacts the hollow block, the fixing rod contacts the L-rod, causing the hollow block to emit a sound, alerting the surrounding crowd. The sound of the hollow block indirectly informs the surrounding crowd that the device has been repaired, further warning them and preventing unauthorized personnel from approaching and touching the device after repair, which could cause injury. The rising of the protective cover opens the ventilation on the surface of the distribution cabinet, increasing the exchange rate of air between the inside and outside of the cabinet. This prevents further damage to the electrical components inside the cabinet due to overheating, improving the efficiency of the device and reducing maintenance costs.

[0008] Preferably, the cleaning mechanism includes a second connecting column, a fixed block, and a scraper. The second connecting column is fixedly connected to the inner wall of the protective cover, the fixed block is fixedly connected to the circumferential surface of the second connecting column, and the scraper is fixedly connected to the circumferential surface of the fixed block. The cleaning mechanism also includes a second inclined block, a rotating column, a roller, and a brush rod. The second inclined block is fixedly connected to the circumferential surface of the second connecting column, the rotating column is rotatably connected to the inner wall of the second inclined block, the roller is fixedly connected to the circumferential surface of the rotating column, and the brush rod is fixedly connected to the circumferential surface of the rotating column. The scraper and... The rollers and brush rods contact the power distribution cabinet body, allowing the scraper to remove dust from the ventilation openings on the cabinet surface. This prevents excessive dust from clogging the ventilation openings, which could lead to overheating of the air inside the cabinet and affect subsequent maintenance costs. The brush rods, driven by the rollers, further clean the ventilation openings on the cabinet surface, extending the device's lifespan and reducing manual cleaning costs.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This safety distribution cabinet for power engineering utilizes the coordinated movement of its cabinet body, opening and closing doors, warning mechanism, cleaning mechanism, motor, reciprocating screw, limit post, long plate, connecting block, pushing block, hinge plate one, night warning sign, elastic telescopic rod, connecting plate, inclined block one, hinge plate two, lamp post, L-shaped rod, and protrusion. This allows the night warning sign to alert surrounding people, reminding them that maintenance is underway in the area and keeping unrelated personnel away, thus improving the safety of the device. The lamp post ensures it is within the line of sight, enhancing the warning effect and preventing blind spots due to varying positions. The movement of the lamp post further enhances the warning effect and improves the efficiency of the device.

[0010] 2. This safety-type distribution cabinet for power engineering uses a combination of components including a hollow block, a fixed plate, a connecting column, a striking block, a connecting long column, a fixed rod, a push block, and a protective cover. The hollow block emits a sound to alert those nearby. This sound indirectly informs them that maintenance is complete, further preventing unauthorized personnel from approaching and touching the device after maintenance, thus avoiding injury. The rising of the protective cover opens the ventilation on the cabinet surface, increasing the air exchange rate between the cabinet and the outside air. This prevents further damage to the electrical components inside the cabinet due to overheating, improving the device's efficiency and reducing maintenance costs.

[0011] 3. This safety-type distribution cabinet for power engineering utilizes the coordinated movement of a connecting column, a fixed block, a scraper, a diagonal block, a rotating column, rollers, and a brush rod. The scraper effectively removes dust from the ventilation openings on the cabinet surface, preventing excessive dust buildup that could clog the openings and cause excessively high internal air temperatures, thus reducing maintenance costs and improving the device's effectiveness. The brush rod, driven by the rollers, further cleans the ventilation openings, extending the device's lifespan and reducing manual cleaning costs. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1-8One embodiment of the present invention is as follows: a safety distribution cabinet for power engineering, comprising a cabinet body 1, an opening and closing door 2 rotatably connected to the inner wall of the cabinet body 1, a motor 5 fixedly connected to the inner wall of the cabinet body 1, a reciprocating screw 6 fixedly connected to the output end of the motor 5, a limit post 7 fixedly connected to the inner wall of the cabinet body 1, a long plate 8 movably connected to the circumferential surface of the reciprocating screw 6, a connecting block 9 fixedly connected to the top of the long plate 8, a pushing block 10 fixedly connected to the top of the connecting block 9, and a hinge plate 11 rotatably connected to the inner wall of the cabinet body 1 via a torsion spring. A night warning sign 12 is fixedly connected to the inner wall of the hinge plate 11. When the device is under maintenance at night, the motor 5 will start, and the output end of the motor 5 will drive the reciprocating screw 6 to move... The rotation of the reciprocating screw 6 causes the long plate 8 to rotate. However, the long plate 8 is limited by the limiting post 7. The limiting post 7 causes the long plate 8 to rise only through the reciprocating groove on the surface of the reciprocating screw 6 during the rotation of the reciprocating screw 6. The rise of the long plate 8 causes the connecting block 9 to rise. The movement of the connecting block 9 causes the pushing block 10 to move. After the pushing block 10 moves a certain distance, the top of the pushing block 10 will contact the hinge plate 11. Through the continued rise of the connecting block 9, the connecting block 9 will cause the pushing block 10 to squeeze and push the hinge plate 11. At this time, the hinge plate 11 will rotate at a certain angle. The rotation of the hinge plate 11 will cause the night warning sign 12 to rotate. The night warning sign 12 rotates at a certain angle. Afterwards, the night warning sign 12 will be perpendicular to the top horizontal plane of the distribution cabinet 1, allowing it to stand upright and alert surrounding people. It will remind and inform them that maintenance is underway in the area, keeping unauthorized personnel away and improving the safety of the device. An elastic telescopic rod 13 is fixedly connected to the inner wall of the distribution cabinet 1. A connecting plate 14 is fixedly connected to the telescopic end of the elastic telescopic rod 13. A wedge block 15 is fixedly connected to the left side of the connecting plate 14. A hinge plate 16 is rotatably connected to the inner wall of the distribution cabinet 1 via a torsion spring. A lamp post 17 is fixedly connected to the inner wall of the wedge block 15. An L-shaped rod 18 is fixedly connected to the bottom of the long plate 8. A protrusion 19 is fixedly connected to the right side of the L-shaped rod 18. The inner wall of the distribution cabinet 1 is equipped with a warning mechanism 3 for maintenance alerts. A cleaning mechanism 4 for dust removal is located on the left side of the cabinet 1. The long plate 8 is slidably connected to the circumferential surface of the limiting post 7. The inclined block 15 contacts the distribution cabinet 1, and the connecting plate 14 also contacts the distribution cabinet 1. During the upward movement of the long plate 8, the upward movement of the long plate 8 will cause the L-rod 18 to move. The movement of the L-rod 18 will cause the protrusion 19 to move. After the protrusion 19 moves a certain distance, it will contact the inclined surface of the inclined block 15 and press and push the inclined block 15. At this time, the inclined block 15, under the pressure of the pushing force, will compress the elastic telescopic rod 13 and move. The movement of the inclined block 15 will cause the lamp post 17 to move. After the lamp post 17 moves a certain distance...The lamp post 17 contacts and presses against the hinge plate 16, opening the hinge plate and bringing the lamp post 17 into the line of sight of the crowd. This increases the warning effect of the device and prevents blind spots in the view of the nighttime warning sign 12 caused by different positions of the surrounding people, thus ensuring that the lamp post 17 is not observed. The movement of the lamp post 17 enhances the warning effect of the device and improves its efficiency.

[0016] The warning mechanism 3 includes a hollow block 301, a fixing plate 302, a connecting column 303, and a striking block 304. The hollow block 301 is fixedly connected to the inner wall of the distribution cabinet 1. The fixing plate 302 is fixedly connected to the left side of the night warning sign 12. The connecting column 303 is fixedly connected to the bottom of the fixing plate 302. The striking block 304 is fixedly connected to the bottom of the connecting column 303. After the device is repaired, the pushing block 10 will move by the downward movement of the long plate 8. The movement of the pushing block 10 will move away from and no longer contact the hinge plate 11. The hinge plate 11 will be reset and rotated by its own torsion spring. The rotation of the hinge plate 11 will activate the night warning sign. When sign 12 rotates to its reset position, the night warning sign 12 will cause the fixing plate 302 to rotate and move. This rotation of the fixing plate 302 will then cause the connecting column 303 to rotate and move. The movement of the connecting column 303 will then cause the striking block 304 to move. The striking block 304 will re-engage with the hollow block 301 and, through the torsion spring force of the hinge plate 11, strike the hollow block 301, producing a sound. This sound indirectly informs those nearby that the device has been repaired, further alerting them and preventing unauthorized personnel from approaching and touching the device after repairs. In case of personnel injury, the warning mechanism 3 also includes a connecting column 305, a fixing rod 306, a push block 307, and a protective cover 308. The connecting column 305 is fixedly connected to the inner wall of the protrusion 19, the fixing rod 306 is fixedly connected to the circumferential surface of the connecting column 305, the push block 307 is fixedly connected to the top of the fixing rod 306, and the protective cover 308 is slidably connected to the inner wall of the distribution cabinet 1. The striking block 304 contacts the hollow block 301, and the fixing rod 306 contacts the L-rod 18. When the L-rod 18 rises, the rise of the L-rod 18 will drive the protrusion 19 to move, and the movement of the protrusion 19 will drive the connecting column 305 to rise and move. The movement of 305 will cause the fixed rod 306 to move, and the movement of the fixed rod 306 will cause the push block 307 to move. After the push block 307 moves a certain distance, the push block 307 will contact the protective cover 308 and squeeze and push the protective cover 308. At this time, after the protective cover 308 is squeezed and pushed by the push block 307, the protective cover 308 can rise. The rise of the protective cover 308 can open the ventilation on the surface of the distribution cabinet 1, increase the exchange speed of air inside the distribution cabinet 1 with the outside air, avoid further damage to the electrical components inside the distribution cabinet 1 due to excessive temperature, improve the efficiency of the device and reduce maintenance costs.

[0017] Working principle: When the device is under maintenance at night, motor 5 will start, and the output of motor 5 will drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 will drive the long plate 8 to rotate. However, the long plate 8 will be limited by the limiting post 7. The limiting post 7 will cause the long plate 8 to rise only through the reciprocating groove on the surface of the reciprocating screw 6 during the rotation of the reciprocating screw 6. The rise of the long plate 8 will drive the connecting block 9 to rise. The movement of the connecting block 9 will drive the pushing block 10 to move. When the pushing block 10 moves a certain distance... After a certain distance, the top of the pushing block 10 will contact the hinge plate 11 and, through the continued rise of the connecting block 9, the connecting block 9 will cause the pushing block 10 to press and push the hinge plate 11. At this time, the hinge plate 11 will rotate at a certain angle. The rotation of the hinge plate 11 will cause the night warning sign 12 to rotate. After rotating at a certain angle, the night warning sign 12 will be perpendicular to the top horizontal plane of the distribution cabinet 1, and the night warning sign 12 can stand up and warn people in the surrounding area. The system can alert and inform surrounding people that the area is under maintenance, allowing unrelated personnel to stay away and improving the safety of the device. During the ascent of the long plate 8, the upward movement of the long plate 8 causes the L-rod 18 to move, which in turn moves the protrusion 19. After moving a certain distance, the protrusion 19 contacts the inclined surface of the inclined block 15 and presses against it. Under this pressure, the inclined block 15 compresses the elastic telescopic rod 13, causing it to move further. The movement of block 15 will cause the lamp post 17 to move. After moving a certain distance, the lamp post 17 will contact the hinge plate 16 and push the hinge plate 16. At this time, the hinge plate 16 can open, and the lamp post 17 can appear in the line of sight of the crowd. This can increase the warning effect of the device and prevent the surrounding crowd from having blind spots in their vision of the night warning sign 12 due to different positions, thus failing to see the lamp post 17. The movement of the lamp post 17 can increase the warning effect of the device and improve the efficiency of the device.

[0018] After the device is repaired, the push block 10 will move by the downward movement of the long plate 8. The push block 10 will move away from and no longer contact the hinge plate 11. The hinge plate 11 will then rotate and reset via its own torsion spring. This rotation will cause the night warning sign 12 to rotate and reset. The night warning sign 12 will then cause the fixing plate 302 to rotate and move. This rotation will cause the connecting column 303 to rotate and move. This movement will cause the striking block 304 to move. The striking block 304 will then re-engage with the hollow block 301 and strike it using the resetting force of the hinge plate 11's torsion spring. The hollow block 301 will then emit a sound, alerting those nearby. The sound of the hollow block 301 indirectly informs those nearby that the device has been repaired, further warning them to avoid being disturbed after the repair is completed. Subsequently, if unauthorized personnel approach and touch the device, resulting in injury, during the upward movement of L-rod 18, the upward movement of L-rod 18 will cause protrusion 19 to move. The movement of protrusion 19 will cause connecting column 305 to move upward. The movement of connecting column 305 will cause fixing rod 306 to move. The movement of fixing rod 306 will cause push block 307 to move. After push block 307 moves a certain distance, push block 307 will contact protective cover 308 and squeeze and push protective cover 308. At this time, after being squeezed and pushed by push block 307, protective cover 308 can rise. The rise of protective cover 308 can open the ventilation on the surface of distribution cabinet 1, increase the exchange speed of air inside distribution cabinet 1 with outside air, avoid further damage to electrical components inside distribution cabinet 1 due to excessive temperature, improve the efficiency of the device and reduce maintenance costs.

[0019] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 4 includes a connecting column 401, a fixing block 402, and a scraper 403. The connecting column 401 is fixedly connected to the inner wall of the protective cover 308, the fixing block 402 is fixedly connected to the circumferential surface of the connecting column 401, and the scraper 403 is fixedly connected to the circumferential surface of the fixing block 402. When the electrical components inside the device are being repaired, the upward movement of the protective cover 308 will cause the connecting column 401 to move, and the movement of the connecting column 401 will cause the fixing block 402 to move. During the movement, the fixed block 402 drives the scraper 403 to move. As the scraper 403 moves, it removes dust from the ventilation openings on the surface of the distribution cabinet 1, preventing excessive dust from clogging the ventilation openings and causing excessively high air temperature inside the cabinet, thus affecting subsequent maintenance costs and improving the effectiveness of the device. The cleaning mechanism 4 also includes a second inclined block 404, a rotating column 405, a roller 406, and a brush rod 407. The second inclined block 404 is fixedly connected to the connecting column 405. The circumferential surface of the distribution cabinet 1 is connected to the inner wall of the inclined block 404. A roller 406 is fixedly connected to the circumferential surface of the rotating column 405, and a brush rod 407 is fixedly connected to the circumferential surface of the rotating column 405. A scraper 403 contacts the distribution cabinet 1, and the roller 406 and brush rod 407 also contact the distribution cabinet 1. Simultaneously, during the upward movement of the connecting column 401, the upward movement of the connecting column 401 will drive the inclined block 404 to move, and the movement of the inclined block 404 will drive the rotating column 405 to move. The movement of the rotating column 405 will... The roller 406 moves, and during its movement, it rotates due to friction with the surface of the distribution cabinet 1. This rotation of the roller 406 causes the rotating column 405 to rotate as it rises. The rotating column 405 then rotates, causing the brush rod 407 to rotate. This brush rod 407, driven by the roller 406, further cleans the ventilation openings on the surface of the distribution cabinet 1, improving the device's lifespan and reducing manual cleaning costs.

[0020] Working Principle: When the electrical components inside the device are being repaired, the upward movement of the protective cover 308 will cause the connecting column 401 to move. The movement of the connecting column 401 will then cause the fixing block 402 to move. During this movement, the fixing block 402 will also cause the scraper 403 to move. The scraper 403, during its movement, can remove dust from the ventilation openings on the surface of the distribution cabinet 1. This prevents excessive dust from clogging the ventilation openings, which could lead to excessively high air temperatures inside the distribution cabinet 1, affecting subsequent maintenance costs and improving the device's performance. Simultaneously, during the upward movement of the connecting column 401... The upward movement of the device will cause the inclined block 404 to move, which in turn will cause the rotating column 405 to move. The movement of the rotating column 405 will cause the roller 406 to move. During the movement of the roller 406, the roller 406 will rotate due to the friction generated by its contact with the surface of the distribution cabinet 1. The rotation of the roller 406 will cause the rotating column 405 to rotate as it rises. The rotating column 405 will rise and rotate, which will cause the brush rod 407 to rotate. At this time, the brush rod 407 can further clean the ventilation openings on the surface of the distribution cabinet 1 under the rotation driven by the roller 406, thereby improving the service life of the device and reducing manual cleaning costs.
