[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a safety drive-away device for dangerous working areas, including an expandable and closable box body, wherein the main body of the safety drive-away device is located in the box body. When not in use, the main body is enclosed inside to provide a certain protection effect, thereby preventing the main body from being bumped during transfer. When in use, the box body is expanded to form a support base, thereby raising the main body to a certain height.

[0024] In this embodiment, the box body includes a square box bottom plate 5 and four rectangular box side plates 17. The bottom edge of each box side plate 17 is hingedly connected to the edges of the box bottom plate 5 by hinges 6 respectively. A triangular box top plate 14 that is bent inwardly is provided on the top of each box side plate 17. When the box body is closed, the box top plates 14 are spliced ​​to form a protective cover plate located on the top.

[0025] In this embodiment, a handle 1 is installed at the middle part of the outer side of a group of box side panels 17 in the alignment position. The handle 1 can improve the operational convenience when carrying and transferring the safe expulsion device.

[0026] A support base plate 4 is fixedly mounted at the bottom of the inner cavity of the box. Figure 1 As shown in the figure, the support base plate 4 is installed and fixed in the middle position of the box bottom plate 5 of the box body. Specifically, the support base plate 4 is square in shape and has connecting holes at the four corners. Threaded rods are arranged at corresponding positions on the box bottom plate 5 and each threaded rod is respectively located in each connecting hole on the support base plate 4 and is fixed with nuts.

[0027] A support rod 10 is installed on the support bottom plate 4, a base 11 is provided at the upper end of the support rod 10, a mounting seat 12 that can swing and adjust the angle is hingedly installed on the base 11, a back frame 13 is installed on the mounting seat 12, and a photovoltaic panel 15 is installed on the back frame 13. Since the mounting seat 12 can be adjusted in angle, the photovoltaic panel 15 can be adjusted in angle. In this embodiment, the mounting seat 12 is an inverted U-shape and an arc-shaped strip hole is provided on the side plate, a threaded hole is provided on the side of the base 11, and a fastening screw is provided in the arc-shaped strip hole and the threaded hole. When the angle of the photovoltaic panel 15 needs to be adjusted, the fastening screw is loosened, and the angle of the photovoltaic panel 15 is adjusted to a suitable position and then the fastening screw is tightened.

[0028] like Figure 1 As shown in , when the safety drive device is not in use, the photovoltaic panel 15 needs to be adjusted to a horizontal position before the box is closed. After the box is closed, the protective cover formed by the top panels 14 of the box is located above the photovoltaic panel 15, which protects the photovoltaic panel 15.

[0029] In this embodiment, a locking assembly is further provided between the photovoltaic panel 15 and the box body, and the locking assembly is used to lock the box body when it is closed to prevent it from expanding automatically. The locking assembly includes a threaded rod 24 arranged around the photovoltaic panel 15 and a lock nut 23 located on the threaded rod 24. A connecting hole is provided at a corresponding position on the top of each box side plate 17 of the box body. When the box body is closed, the threaded rod 24 is located in the connecting hole and the lock nut 23 is located on the outside of the box side plate 17. When the box body needs to be expanded, each lock nut 23 is removed from the outside, and each box side plate 17 can be expanded outward.

[0030] A support 3 is installed in the middle of the support rod 10, and a wind wheel 2 and a rotating reflector 7 are installed on the support 3, and the rotating shafts of the wind wheel 2 and the rotating reflector 7 are connected by transmission. In this embodiment, a clamp 9 is installed in the middle of the support rod 10, and the inner end of the support 3 is hingedly connected to the clamp 9, and the lower ends of the rotating shafts of the wind wheel 2 and the rotating reflector 7 are driven by a gear set 8. In this way, the support 3 and its attached parts can be folded down and lifted to a horizontal state. When not in use, it can be folded down, which can improve the compactness of the overall structure and reduce the size of the box. When in use, it can be lifted to a horizontal state. Under the action of wind force, the rotation of the wind wheel 2 is transmitted to the rotating reflector 7 through the gear set 8 at the bottom, and the rotating reflector 7 performs synchronous rotation. The rotating reflector 7 achieves a prompting effect of attracting the attention of surrounding people by reflecting sunlight.

[0031] In this embodiment, the rotating reflector 7 includes a rotating base, and a plurality of rotating blades arranged at equal angles in the circumferential direction are installed on the side of the rotating base. A reflective lens is installed on the rotating blade. The reflective lens can be selected as an ordinary plane mirror and fixed to the rotating blade by bonding.

[0032] A side bracket 26 is installed at the root of the support rod 10, and a control box 16 with a control circuit board and a battery inside is installed on the side bracket 26. It also includes a detection sensor 20 for detecting the approach of a person and an audible and visual alarm 22 for generating a warning and expelling effect. The photovoltaic panel 15, the detection sensor 20 and the audible and visual alarm 22 are all connected to the control circuit board through cables. The audible and visual alarm 22 includes an optical module (such as an LED light group) and an acoustic module (such as a speaker), which are respectively used to generate a warning light and a warning and expelling sound effect. Furthermore, a plurality of wiring terminals 25 are provided on the side of the control box 16, and plug-in terminals are provided at the ends of the cables of the photovoltaic panel 15, the detection sensor 20 and the audible and visual alarm 22, and the plug-in terminals are plug-connected with the corresponding wiring terminals 25.

[0036] Directions:

[0037] Figure 1 The figure shows the non-use state. Figure 3 The figure shows the use state. It can be seen that after the safety driving device is transferred to the dangerous operation area designated at the construction site, the locking components are first released, and the side box panels 17 of the box body are unfolded outwards and further turned downwards until the side box panels 17 form a supporting base. At this time, the safety driving device is exposed, and the box top panels 14 fall on the ground. At this time, a pressure block 27 can be set on each box top panel 14 to improve the overall stability; then the support 3 is lifted to a horizontal state, the angle of the photovoltaic panel 15 is adjusted and set, and the detection sensor 20 and the sound and light alarm 22 are respectively set to the appropriate positions of the dangerous operation area;

[0038] When a person approaches a dangerous working area, the detection sensor 20 detects the person's approach, and the control box 16 sends a command to the sound and light alarm 22, which simultaneously generates a warning light and a warning sound effect. During the use of this safe driving device, the wind wheel 2 drives the rotating reflector 7 to rotate under the action of wind force, and the rotating reflector 7 produces a dynamic reflection effect on sunlight. This reflected light will also attract the attention of surrounding personnel, producing a danger warning effect.
