[0031] In this embodiment, the warning component 3 also includes a support plate 31 connected to the bracket 2 through a rotating shaft and fixed to the warning plate 32. The warning plate 32 is provided with at least three and presents an S-shaped folding structure when folded. The warning plate 32 located in the middle is connected to another warning plate 32 through a hinge 33, and the two hinges 33 are respectively located on different sides of the warning plate 32.

[0032] In this embodiment, when in use, the bracket 2 is fixed to the outside of the protective plate 1. In this embodiment, four brackets 2 are provided to ensure the stability and reliability of the device. The bracket 2 is rotatably connected to the warning component 3, so that the warning component 3 can be deployed when needed, and the warning plate 32 connected together by the hinge 33 forms a structure that can be deployed and retracted.

[0033] When a warning is needed, the warning plate 32 can be unfolded to form a large warning area. When it is not needed, it can be retracted to save space. The isolation belt 71 is located inside the warning plate 32. When the warning plate 32 is unfolded, the isolation belt 71 will also be unfolded to form an isolation barrier to further isolate electrical equipment and personnel.

[0034] In this embodiment, the limiting column 72 and the jacket 73 are respectively arranged on both sides of the warning plate 32 and fixedly installed with the isolation belt 71, which can effectively limit the expansion range of the isolation belt 71 and ensure that the isolation belt 71 will not fall off or shift when expanded.

[0035] In this embodiment, the waterproof cloth 61 covers the periphery of the power equipment to play a role in waterproofing and dustproofing. The winding roller 64 and the rotating plate 66 are respectively arranged at the upper and lower ends of the waterproof cloth 61, and rotate with the column 62. The winding roller 64 is used to roll up the top of the waterproof cloth 61, and the rotating plate 66 is used to fix and tow the bottom of the waterproof cloth 61. When it is necessary to adjust the coverage of the waterproof cloth 61, it can be achieved by rotating the winding roller 64 and the rotating plate 66. The steel wire 65 is towed at the bottom of the waterproof cloth 61 and connected to the rotating plate 66. The steel wire 65 can effectively enhance the stability and wind resistance of the waterproof cloth 61, and prevent the waterproof cloth 61 from being blown up or torn in strong wind weather.

[0036] In this embodiment, by unfolding the warning component 3 and the isolation component 7, a large warning area can be formed to remind personnel to pay attention to the safe distance and dangerous areas of the power equipment. The protection component 6 provides all-round protection and isolation for the power equipment through the coordinated action of the column 62, the waterproof cloth 61, the winding roller 64, the rotating plate 66 and the steel wire 65. The safety warning device can be adjusted and optimized according to the actual situation of the power equipment. At the same time, the connection and cooperation between the various components are tight and reliable, ensuring the safety and stability of the entire device, providing all-round safety protection for personnel and equipment around the power equipment, and improving the safety and warning effect around the power equipment.

[0037] In this embodiment, a warning sticker 34 is pasted on the outside of the warning plate 32, and the warning sticker 34 is a fluorescent warning sticker 34; pasting the fluorescent warning sticker 34 on the outside of the warning plate 32 further enhances the effect and practicality of the entire safety early warning device. The fluorescent warning sticker 34 is made of fluorescent material and can maintain high visibility both during the day and at night. During the day, the fluorescent material can absorb and reflect sunlight to make the warning sticker 34 more eye-catching. At night or in a dimly lit environment, the fluorescent material can emit soft fluorescence to provide personnel with a clear warning sign.

[0038] In this embodiment, the fluorescent warning sticker 34 is self-adhesive and can be easily pasted on the outside of the warning plate 32. At the same time, its viscosity is moderate and will not damage the surface of the warning plate 34. It is also easy to remove or replace when needed. The fluorescent warning sticker 34 enables it to maintain a striking warning effect in various environments. When the warning plate 32 is unfolded, the fluorescent warning sticker 34 can attract the attention of personnel and remind them to pay attention to the safe distance and dangerous areas of the power equipment, so that personnel can see the warning signs earlier when approaching the power equipment, so that they have enough time to react and avoid safety accidents.

[0039] In this embodiment, the column 62 is composed of a vertical plate 621 and a horizontal plate 622 which are perpendicular to each other. The winding roller 64 and the rotating plate 66 are respectively rotatably cooperated with the horizontal plate 622. The winding roller 64 and the rotating plate 66 are respectively provided with motors for controlling their rotation. The column 62 has a concave structure and the waterproof cloth 61 is located in its concave part and slides up and down. A top box 63 fixedly installed with the horizontal plate 622 is provided on the top of the winding roller 64. The column 62 has a concave structure, which can effectively enhance the stability of the column 62 and provide space for the waterproof cloth 61 to slide up and down, thereby realizing effective support and guidance for the waterproof cloth 61, simplifying the unfolding and folding process of the waterproof cloth 61, and improving the reliability and durability of the entire protective assembly 6.

[0040] In this embodiment, the winding roller 64 and the rotating plate 66 are respectively rotatably cooperated with the transverse plate 622 so that they can rotate freely relative to the transverse plate 622, thereby realizing the winding and unfolding of the waterproof cloth 61. The winding roller 64 and the rotating plate 66 are respectively provided with motors for controlling their rotation. Through the drive of the motor, the winding roller 64 and the rotating plate 66 can be accurately controlled, thereby realizing the automatic winding and unfolding of the waterproof cloth 61.

[0041] In this embodiment, the top box 63 is arranged on the top of the winding roller 64 and is fixedly installed with the cross plate 622, which enhances the stability of the winding roller 64 and provides it with additional support and protection. The top box 63 can also serve as an auxiliary component of the winding roller 64 to help better wind up the waterproof cloth 61. When the winding roller 64 rotates, the waterproof cloth 61 will be gradually rolled into it, and the top box 63 can prevent the waterproof cloth 61 from slipping or deforming during the winding process. By covering the waterproof cloth 61, rain and dust can be effectively prevented from entering the interior of the power equipment, thereby protecting its normal operation and extending its service life. Through the drive of the motor and the concave structure design of the column 62, the waterproof cloth 61 can be flexibly adjusted and unfolded, which not only adapts to the use requirements under different environments and conditions, but also improves the practicality and flexibility of the entire protective assembly 6, ensuring the stability and safety of the entire protective assembly 6 during long-term use.

[0042] In this embodiment, two isolation belts 71 are provided in the warning plate 32, and the limiting column 72 and the jacket 73 are respectively located on both sides of the warning plate 32. In this embodiment, the limiting column 72 is a cylindrical structure, and the jacket 73 is an unsealed circular ring structure. When the limiting column 72 and the jacket 73 are buckled, the isolation belts 71 on both sides thereof are in a vertical or parallel structure with the waterproof cloth 61. The limiting column 72 and the jacket 73 are alternately distributed on both sides of the warning plate 32. The two isolation belts 71 are provided in the warning plate 32, which can effectively increase the isolation effect and safety.

[0043] In this embodiment, when the warning plate 32 is unfolded, the two isolation belts 71 can be interlocked with each other to form a more obvious isolation area, effectively preventing people from entering the dangerous area. The cooperation between the cylindrical structure of the limiting column 72 and the jacket 73 with an unsealed circular ring structure can achieve the interlocking of the two, and can be easily removed or replaced when necessary. When the limiting column 72 and the jacket 73 are interlocked, the limiting column 72 and the jacket 73 are alternately distributed on both sides of the warning plate 32, so that the distribution of the isolation belts 71 on the warning plate 32 is more uniform and stable. At the same time, the alternating distribution can also reduce the stress concentration problem caused by the concentrated distribution, thereby improving the durability and reliability of the entire isolation assembly 7.

[0044] In other embodiments, the positions and quantities of the limiting posts 72 and the jackets 73 may be adjusted according to actual needs to change the layout of the isolation zone 71 to adapt to different application scenarios and warning requirements.

[0045] In this embodiment, a lifting cylinder 5 is provided between the protective plate 1 and the protective assembly 6. One end of the lifting cylinder 5 is connected to the protective plate 1, and the other end is connected to the protective assembly 6. The connection methods include bolt connection, welding or snap connection, etc. The lifting cylinder 5 is driven to realize the lifting movement between the protective plate 1 and the protective assembly 6, so as to meet the warning requirements at different heights. In an emergency, the lifting cylinder 5 can be used to quickly lift the protective plate 1 or the protective assembly 6 to a certain height to form a more obvious isolation and warning area, thereby further ensuring the safety of personnel and equipment.

[0046] In this embodiment, an early warning device 4 is fixed on the top of the protective plate 1, and a sound module and a light module are arranged inside the early warning device 4. In high-risk areas such as around power equipment, the early warning function of the early warning device 4 can greatly reduce the probability of safety accidents. The early warning device 4 can adapt to different application scenarios and early warning needs. Whether it is an indoor or outdoor environment, whether it is day or night, the early warning device 4 can send effective early warning information through sound and light.

[0047] In this embodiment, the sound module is responsible for issuing warning sounds, including alarm sounds, prompt sounds, etc., which can be customized according to different warning levels and scenarios to more effectively attract people's attention and convey warning information.

[0048] In this embodiment, the lighting module is responsible for emitting warning lights, including flashing warning lights, signal lights of different colors, etc., which can visually attract the attention of personnel, and can also convey different warning information through different colors and flashing modes. Warnings through both sound and light can more effectively attract the attention of personnel, improve the accuracy and timeliness of warnings, ensure that they can play an important role in various emergency situations, ensure that personnel can respond quickly, and more effectively protect the safety of personnel and equipment.

[0049] The working principle and use process of the present invention are as follows: the protective component 6 is installed outside the power equipment, and the end thereof contacting the ground is fixed to the ground by rivets. When a safety warning is needed, the three warning plates 32 are unfolded and placed perpendicular to the protective plate 1, and the isolation belt 71 is pulled out according to the requirements of different warning areas, and the limit column 72 is buckled into the jacket 73. When maintenance is needed, it is only necessary to open the isolation component on the side that needs to be repaired, and let the winding roller 64 drive the waterproof cloth 61 to be rolled up. After the maintenance is completed, it is only necessary to rotate the rotating plate 66 so that the steel wire 65 pulls the waterproof cloth 61 to cover the bottom again.
