[0002] The strong current construction environment is complex, and the danger coefficient is high, so the safety protection of the construction personnel is very important. At present, most strong current constructions rely on traditional protective equipment, such as safety helmets, insulating gloves and safety ropes. These devices can provide certain protection, but the function is relatively single. For example, the insulating gloves are only for hand electric shock protection, and are easy to wear during use, which affects the insulating performance. The safety helmet mainly protects the head from impact, and is insufficient for electric shock risk protection. In addition, with the development of intelligent construction, the traditional protective equipment cannot monitor the body state of the construction personnel and the operation environment parameters in real time. Once danger occurs, it is difficult to give timely early warning and rescue. Moreover, the carrying and storage of the traditional protective device are not convenient due to the limited space of the construction site, which affects the construction efficiency. In summary, it is extremely urgent to develop a multifunctional, intelligent and portable strong current construction protective device to meet the safety and efficient needs of modern strong current construction.

[0031] In the embodiment, device housing group 1 and protective belt installation group 2, lifting group 3 constitute the protective device for high voltage construction of the application, realize a kind of protective device for high voltage construction, the construction protective device in the application, only the device that needs protection can use the equipment of the application, the application does not limit specific protective device category.

[0032] In the embodiment, the fixed shaft 12 is located inside the device base 11, which provides support for the protective belt installation group 2 to ensure stability.

[0033] In the embodiment, the fixed seat 13 is fixed on one side of the device base 11, which mainly functions to be clamped with the protective belt installation group 2 of another set of protective devices, so as to connect multiple protective devices to form a larger protection area.

[0034] It should be noted that the warning sign 32 can be pasted with a reflective strip to warn the surrounding personnel that high-voltage construction is in progress.

[0035] Specifically, the protective belt installation group 2 includes: a reel 25 rotatably arranged on the fixed shaft 12; a spiral spring 21 arranged inside the device base 11, one end connected above the fixed shaft 12, and the other end connected below the reel 25, for resetting the reel 25; a connecting head 23 sliding on the groove provided on one side of the device base 11; and a connecting groove 24 provided on one side of the connecting head 23 and clamped with the fixed seat 13 of another set of protective devices.

[0036] In the embodiment, the connecting head 23 is pulled, and the belt body 22 is unwound from the reel 25, while the reel 25 rotates, and the spiral spring 21 is stretched. When the connecting head 23 is released, the spiral spring 21 contracts, driving the reel 25 to reverse, so that the belt body 22 is retracted, facilitating the unwinding and retraction of the belt body 22, and enabling the connection and fixation of the belt bodies 22 of multiple sets of protective devices.

[0037] Specifically, the fixed seat 13 is provided with a fixed groove for clamping with the connecting groove 24 of another set of protective devices to fix the position of the belt body 22.

[0038] As a preferred embodiment, the fixed groove 12 cooperates with the connecting groove 24 to connect the two sets of protective devices and fix the position of the belt body 22.

[0039] Specifically, the belt body 22 is wound around the periphery of the reel 25, one end connected to the reel 25, and the other end connected to the connecting head 23. Pulling the connecting head 23 unwinds the belt body 22.

[0040] It should be noted that pulling the connecting head 23 unwinds the belt body 22 from the reel 25 to form a protective barrier, which physically isolates the high-voltage construction area.

[0041] Embodiment 2:

[0042] On the basis of embodiment 1, in order to further improve the quick unwinding of the belt body 22, the belt body 22 is wound around the periphery of the reel 25.

[0043] Specifically, the spool 25 is in the shape of an "I" and the tape 22 is wound around the middle of the "I" shape of the spool 25 to define the winding position of the tape 22.

[0044] As a preferred implementation, the "I"-shaped structure restricts the lateral movement of the tape 22 during the winding and unfolding process, so that it is neatly wound on the reel 25, ensuring that the tape 22 is wound in an orderly manner and avoiding the tape 22 from being wound haphazardly on the reel 25.

[0045] Specifically, the lifting assembly 3 includes: a stud 31, arranged inside the scroll 25; a slide 33, arranged on both sides of the stud 31, with the slide 33 having a sliding block 14 connected inside; and a warning sign 32, fixedly connected above the stud 31 for warning purposes.

[0046] It should be noted that when the connector 23 is pulled to unfold the belt 22, the belt 22 drives the reel 25 to rotate. Since the stud 31 is connected to the internal thread of the reel 25, the rotation of the reel 25 causes the stud 31 to move upward, thereby causing the warning sign 32 to rise, so that the warning sign 32 automatically rises at the same time as the protective belt unfolds.

[0047] Example 3:

[0048] Based on embodiment 2, in order to raise and lower the warning sign 32, the warning sign 32 is fixedly connected to the top of the stud 31;

[0049] Specifically, the stud 31 is internally threaded to the reel 25. When the connector 23 is pulled, the connector 23 drives the belt 22 to be pulled out, and the belt 22 drives the reel 25 to rotate, causing the stud 31 to move upward and the warning sign 32 to rise.

[0050] In this embodiment, the stud 31 is internally threaded to the reel 25, causing the belt 22 to rotate and the reel 25 to move the stud 31 upward, thus automatically raising and lowering the warning sign 32.

[0051] When in use, to ensure safety at the site of high-voltage construction, place the device base 11 in the predetermined position, pull the connector 23 by hand, the belt 22 unfolds, the spiral spring 21 stretches, and the connector 23 is fixed to the next set of fixed seats 13. At the same time as the belt 22 unfolds, the reel 25 rotates, and the internal stud 31 rotates and rises, raising the warning sign 32. The device is then erected. When it is necessary to retract the device, the connector 23 is contacted and fixed from the next set of fixed seats 13. At this time, the spiral spring 21 returns to its original position, the belt 22 is wound back onto the reel 25, and the stud 31 descends, causing the warning sign 32 to retract. The device is then retracted.

[0052] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
