Description

Technical Field

[0001] The utility model relates to the technical field of safety warnings, in particular to a safety warning device. Background Art

[0002] Safety warning devices refer to equipment or facilities used to remind and warn people of potential dangers. They usually use sound, light, color, text symbols and other means to convey danger information so that people can take timely measures to avoid accidents. There are many types and forms of safety warning devices, including but not limited to safety warning signs, warning lights, safety slogans, etc. These devices are particularly common in medical places, facilities and dangerous areas, such as warning signs such as "Beware of slippery roads", "Beware of holes", "High voltage electricity", etc., all of which are to remind people to pay attention to potential dangers in the surrounding environment.

[0003] In short, safety warning devices play a vital role in maintaining public safety and preventing accidents, and people should pay attention to and use these devices correctly.

[0004] In some cities, some underpasses (such as underground culverts built to avoid railways) have been built for a long time and have limited drainage capacity. Whenever heavy rain comes, the underpass is easily flooded, and it is necessary to place safety warning equipment before entering the underpass. However, conventional safety warning equipment usually adopts simple direct and warning signs. In bad weather, deeper accumulated water and airflow can easily overturn the equipment. In order to solve this technical problem, the utility model proposes a safety warning device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model comprises a vehicle base, a water tank, a warning plate, an expansion plate, load-bearing wheels and a telescopic belt. The water tank is provided with a water inlet and a water outlet. Water can be poured into the water tank through the water inlet, which can quickly increase the overall weight of the device. The three load-bearing wheels can be shifted downward, thereby increasing the contact area between the telescopic belt and the ground. When the device is removed, it is only necessary to drain the water inside the water tank. This allows the device to increase its overall weight and the contact area between the ground when the rainy season comes, and can resist accumulated water and strong winds, thus solving the problem that deeper accumulated water and airflow can easily overturn the device.

[0014] In the utility model, through the cooperation between the hydraulic rod, the expansion plate and the barbs, the hydraulic rod can drive the expansion plate to rotate downward when extended, thereby driving the barbs to adhere to the asphalt pavement, so that the barbs can barely hook the gaps between particles on the asphalt pavement, thereby increasing the grip of the equipment when it is deployed.
