Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering devices, in particular to a safety protection device for electrical engineering. Background Art

[0002] With the continuous progress of society, people pay more attention to construction safety when working, especially in building construction projects. In construction, it is often necessary to carry out electrical engineering construction on the building to make the building have electrical equipment and become a modern building. However, when carrying out electrical engineering construction on the exterior of the building during construction, safety protection devices are often required to protect the safety of construction workers. For the safety of electrical equipment, electrical equipment is often installed at a certain height. At this time, certain high-altitude construction is required, and construction workers need to be sent to the construction area for construction. However, the existing protection device is only a guardrail, and its protection performance is low.

[0003] The Chinese patent with announcement number CN215484506U discloses a safety protection device used in electrical engineering, including a lifting platform and a lifting device located below the lifting platform, the top of the lifting platform is fixedly connected to a ring guardrail, the inner side wall of the ring guardrail is provided with a convex groove, and the convex groove is arranged around, the inner wall of the convex groove is slidably connected to a sliding block, the side of the sliding block is fixedly connected to a connecting rod, the other end of the connecting rod passes through the convex groove and is fixedly connected to a fixed plate, the top of the fixed plate is fixedly connected to an electric cylinder, the output end of the electric cylinder is fixedly connected to a telescopic foot sleeve, the telescopic foot sleeve includes a first arc plate, a second arc plate and a spring, the ends of the first arc plate and the second arc plate are fixedly connected to the connecting plate, the spring is fixedly connected to the inner side of the connecting plate, and a limiting component is provided on the side of the connecting plate.

While this design provides additional safety for workers, the spring-loaded telescopic leg sleeves, once attached to the worker's calf, may restrict leg movement. This can be particularly problematic in situations requiring frequent movement or extensive work, where the tightness of the leg sleeves can hinder movement, impacting both efficiency and safety.

[0005] Therefore, we propose a safety protection device for electrical engineering to solve the above problems. Utility Model Content

[0027] The protection mechanism includes an embracing protection unit and an outer protection unit;

[0028] The outer protection unit includes a guardrail 301, a protective door 302, a rotating shaft 303, a block 304 and an adapter block 305. The lifting platform 3 is fixedly connected with a guard plate on all sides. The guardrail 301 is fixedly connected to the guard plate to provide edge protection to prevent people from falling from the edge of the lifting platform. A through slot is provided on the front of the protective plate. The blocks 304 are fixedly connected to the back side of the right side of the through slot in groups of two. The adapter block 305 is connected between the two groups of blocks 304 by rotating through the rotating shaft 303. A locking structure is provided on the left side of the protective door 302. It allows people to enter and exit the lifting platform while providing an additional safety barrier. The flexible opening and closing of the protective door can be achieved through the combination of the rotating shaft 303, the block 304 and the adapter block 305. The locking structure includes a lock block 6, a placement slot 601, a connecting rod 602, and a slider 603. The back of the lock block 6 is fixedly connected to the front of the slider 603. The placement slot 601 is located on the front of the protective plate. The connecting rod 602 is fixedly connected to the placement slot 601 at both ends.

The threaded rod 503 has opposite threads at both ends, and the screw nut 502 is threaded onto each end. The protective ring 504 is semicircular in shape. Rotating the threaded rod 503 drives the screw nut 502 and protective ring 504 along the threaded rod. The threaded connection enables the protective ring 504 to move in either the same or opposite directions. The protective ring 504 clips onto the sides of the person's body, providing an additional protective barrier while maintaining the electrical engineer's line of sight and operating space.

[0030] Working Principle: Move lift 1 near the electrical engineering work area. Use handle 101 and support base 2 to ensure stable positioning of the device. Adjust the height of lift platform 3 using lift 1 according to work needs. To enter or exit lift platform 3, pull lock block 6. The spring activates protective door 302, which opens. Once inside lift platform 3, close protective door 302 and lock it to the protective plate using the locking mechanism. Guardrail 301 provides edge protection to prevent people from falling over the edge of the lift platform.

[0031] An electrical engineer stands on lift platform 3, ready to begin work. He activates motor 501, rotating threaded rod 503. Screw nut 502 moves along the threaded rod, driving protective rings 504 toward the side of the worker until they lock onto the worker. Protective rings 504 provide an additional barrier while maintaining visibility and working space. Once the work is complete, lift platform 3 is lowered to the ground using elevator 1.
