Problems solved by technology

The warning device communicates information by setting up a corresponding wireless connection device between the driver and the maintenance worker. Although it plays a good role in safety warning, it is impractical to apply in practice. Generally speaking, The maintenance of roads is not very frequent, and it is a huge project to install wireless receivers on every vehicle. There are hundreds of millions of cars in China, all of which are safe and costly. It is extremely difficult to implement , so the use of this alarm is only theoretically possible

Embodiment 1

[0019] see Figure 1-3 , a kind of expressway maintenance worker's work warning device, comprises warning device body 12, display screen 19; In the upper support frame 13 of L-shaped structure, the upper and lower ends of the rotating shaft 17 are screwed with lock nuts that fix the upper support frame 13 and the warning plate 18 mutually. The lower side of the upper support frame 13 is provided with the lower support frame 27 with the same structure as the upper support frame 13, the bottom end of the upper support frame 13 and the top of the lower support frame 27 are fixedly connected with threaded rods 16, two groups of threaded rods 16 up and down The middle part is threadedly connected with the threaded barrel 15 that controls the distance between the upper support frame 13 and the lower support frame 27. By rotating the threaded barrel 15, the length of the threaded rod 16 entering and leaving the threaded barrel 15 is controlled, thereby adjusting the upper support fra...

Embodiment 2

[0023] On the basis of Embodiment 1, two groups of vertical columns are fixedly installed on the left and right sides of the top of the warning board 18, and a group of rotating rods 25 are connected to the top of the columns for horizontal rotation, and the left end of the rotating rod 25 is connected to a rotating motor. Start the rotating motor to drive the rotating rod 25 to rotate. A group of solar panels 22 are fixedly installed on the upper side of the rotating rod 25 through the connecting rod. The operation of the electric energy generated is stored in the electric storage box 26, and then supplied to the entire alarm body 12 for use. The rotating motor is set as a servo motor, and by setting, its operating time is consistent with the daily sun movement, thereby driving the solar panel 22 to rotate, so that the solar panel 22 can receive the best sunlight at all times, thereby Generate electricity with maximum efficiency.

Abstract

The invention relates to the technical field of expressway safety equipment, and discloses an expressway maintenance worker work warning indicator which comprises a warning indicator body and a display screen. The warning indicator body comprises a rectangular plate type structure warning plate. The middle of the left side wall of the warning plate is rotationally connected with a group of upper supporting frames of an L-shaped structure through a rotating shaft. A group of mounting clamping plates are fixedly mounted at the tail end of the bottom transverse section of a lower supporting frame; a display screen is arranged at the lower part of the front side surface of the warning plate; a group of wireless receivers are fixedly mounted at the top of the warning plate; the wireless receivers are wirelessly connected with a camera which is arranged on one side of an expressway maintenance area and used for shooting the condition of the expressway maintenance area; and two groups of warning loudspeakers electrically connected with the display screen are symmetrically arranged at the upper parts of the left side wall and the right side wall of the warning plate. The warning indicatorhas the advantages of being good in warning effect, capable of saving energy, environmentally friendly, high in flexibility and convenient to adjust and install.

Description

technical field [0001] The invention relates to the technical field of expressway safety equipment, in particular to a work warning device for expressway maintenance workers. Background technique [0002] Today, with the rapid development of expressways, maintenance workers on expressways have become a high-risk occupation, and this occupation is dominated by women and older people.
