When the staff approaches the protective box 8, the sealing cover 4 can be intelligently opened and closed by the automatic opening and closing system 13, which is convenient for the staff to open and close the lock core 7. After the sealing cover 4 is closed, the lock core 7 can be protected inside the protective box 8 to prevent the harsh external environment from damaging the lock core 7. This avoids the problem that the lock core 7 of most existing outdoor high-voltage distribution cabinets 1 is not intelligent enough and does not have a protective structure. When the outdoor environment is harsh, dust and rainwater can easily enter the lock core 7 to cause blockage and corrosion to the lock core 7, affecting the smooth opening and closing of the lock core 7.
[0027] As a technical optimization solution of the utility model, the bottom of the electric telescopic rod 10 is fixedly connected to the bottom of the inner wall of the protective box 8, there are two electric telescopic rods 10, the top of the telescopic end of the electric telescopic rod 10 is fixedly connected to the surface of the sealing cover 4, and the input end of the electric telescopic rod 10 is unidirectionally electrically connected to the output end of the control module 12.
[0028] In this embodiment: a staff member holds a key close to the miniature waterproof infrared sensor 5. At this time, the miniature waterproof infrared sensor 5 senses the infrared rays radiated by the human body and transmits a signal to the control module 12. At this time, the control module 12 will simultaneously control the telescopic ends of the two electric telescopic rods 10 to extend upward, so as to lift the sealing cover 4 upward, thereby achieving the effect of driving the sealing cover 4 to move upward.
[0029] As a technical optimization solution of the present invention, the rear side of the illuminating lamp 11 is fixedly connected to the rear side of the inner wall of the protection box 8 , and the input end of the illuminating lamp 11 is unidirectionally electrically connected to the output end of the control module 12 .
[0030] In this embodiment, when the miniature waterproof infrared sensor 5 senses the infrared rays radiated by the human body, it transmits the signal to the control module 12 , and the control module 12 can control the lighting lamp 11 to light up the lock cylinder 7 , thereby achieving the effect of illuminating the lock cylinder 7 .
[0031] As a technical optimization solution of the present invention, the input end of the automatic opening and closing system 13 is unidirectionally electrically connected to the power supply module 14 .
[0032] In this embodiment, the automatic opening and closing system 13 is powered by the power supply module 14 so that the automatic opening and closing system 13 can work normally, thereby achieving the effect of enabling the automatic opening and closing system 13 to work normally.
[0033] As a technical optimization solution of the present utility model, a through hole 9 is opened inside the protection box 8 , and the surface of the lock core 7 is fixedly connected to the inner wall of the through hole 9 .
[0034] In this embodiment: by passing the lock core 7 through the through hole 9 and fixedly connected to the inner wall of the through hole 9, the lock core 7 can be extended to the inside of the protective box 8, thereby achieving the effect of facilitating the lock core 7 to extend to the inside of the protective box 8.
[0035] As a technical optimization solution of the present invention, the surface of the sealing cover 4 contacts the inner wall of the protection box 8 .
[0036] In this embodiment: when the miniature waterproof infrared sensor 5 cannot sense the infrared rays radiated by the human body, the control module 12 will control the telescopic ends of the two electric telescopic rods 10 to move downward at the same time, so that the surface of the sealing cover 4 contacts the inner wall of the protection box 8, and the sealing cover 4 can protect the lock core 7, thereby achieving the effect of protecting the lock core 7.
[0037] As a technical optimization solution of the utility model, a sealing sheet 6 is fixedly connected to the surface of the sealing cover 4 , and the surface of the sealing sheet 6 is in contact with the surface of the protective box 8 .
[0038] In this embodiment, the sealing sheet 6 can seal the gap between the sealing cover 4 and the protective box 8 by contacting the surface of the sealing sheet 6 with the surface of the protective box 8, thereby achieving the effect of sealing the gap between the sealing cover 4 and the protective box 8.
[0039] As a technical optimization solution of the present utility model, the protection box 8 and the sealing cover 4 are both made of corrosion-resistant engineering plastics, and the sealing sheet 6 is made of corrosion-resistant rubber.
[0040] In this embodiment: since the protective box 8 and the sealing cover 4 are both made of corrosion-resistant engineering plastics, the service life of the protective box 8 and the sealing cover 4 can be extended. Since the sealing sheet 6 is made of corrosion-resistant rubber, the sealing sheet 6 has a longer service life, thereby achieving the effect of extending the service life of the protective box 8, the sealing cover 4 and the sealing sheet 6.
[0041] Working principle: First, when using the outdoor high-voltage distribution cabinet 1, the lock core 7 is passed through the through hole 9 and fixedly connected to the inner wall of the through hole 9. At this time, the lock core 7 can be extended to the inside of the protective box 8. When the lock core 7 needs to be opened, the staff holds the key close to the miniature waterproof infrared sensor 5. At this time, the miniature waterproof infrared sensor 5 senses the infrared rays radiated by the human body and transmits the signal to the control module 12. At this time, the control module 12 will simultaneously control the telescopic ends of the two electric telescopic rods 10 to extend upward, so that the sealing cover 4 can be lifted up, and the protective box 8 can be opened. At the same time, the control module 12 controls the lighting lamp 11 to light up, and the lighting lamp 11 can illuminate the staff's hand and reflect the light to the lock core 7, so as to facilitate the insertion of the key into the lock core 7 for unlocking. When the staff pulls out the key, the miniature waterproof infrared sensor 5 can no longer sense the infrared rays radiated by the human body and will control the two electric telescopic rods through the control module 12. The telescopic ends of the rod 10 move downward at the same time, so that the surface of the sealing sheet 6 contacts the surface of the protective box 8. The sealing sheet 6 can seal the gap between the sealing cover 4 and the protective box 8, and the lock core 7 can be protected inside the protective box 8. At the same time, the control module 12 will control the lighting lamp 11 to turn off. When the staff approaches the protective box 8, the sealing cover 4 can be intelligently opened and closed, which is convenient for the staff to open and close the lock core 7. After the sealing cover 4 is closed, the lock core 7 can be protected inside the protective box 8 to prevent the harsh external environment from damaging the lock core 7. This avoids the problem that the lock core 7 of most existing outdoor high-voltage distribution cabinets 1 is not intelligent enough and does not have a protective structure. When a harsh environment occurs outdoors, dust and rainwater can easily enter the lock core 7 to cause blockage and corrosion of the lock core 7, affecting the smooth opening and closing of the lock core 7. The automatic opening and closing system 13 is powered by the power supply module 14, so that the automatic opening and closing system 13 can work normally.
[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
