Description

Technical Field

[0001] The utility model relates to a road construction safety isolation alarm device. Background Art

[0002] At present, during road construction, in order to ensure road traffic safety, road isolation guardrails are generally installed on the construction section to improve urban traffic efficiency and reduce the incidence of accidents. For example:

[0003] Patent "A Road Isolation Guardrail" with authorization announcement number CN212896053U, the road isolation guardrail comprises: a first guardrail; a second guardrail, which is slidably connected to the first guardrail, the road isolation guardrail has an open state in which the second guardrail moves toward the first guardrail and a closed state in which the second guardrail moves away from the first guardrail; and a driving mechanism, which is transmission-connected to the second guardrail, and is used to drive the road isolation guardrail to switch between an open state and a closed state. In the embodiment of the utility model, the second guardrail is driven by the driving mechanism to move toward or away from the first guardrail to open or close the road isolation guardrail, replacing the traditional all-fixed guardrail. In the section where the road guardrail needs to be opened or closed, the guardrail can be opened to allow vehicles to pass or closed to block traffic. The structure is simple, easy to install, easy to maintain, saves manpower, improves work efficiency, ensures traffic safety, and improves traffic efficiency. Although compared with the traditional all-fixed guardrail, it has strong mobility and low disassembly and assembly cost. However, the material reusability rate is low, and people and animals cannot be discovered and stopped in time. There is no convenient advantage for temporary short-term channel isolation construction.

[0004] Patent "A retractable safety fence structure" with authorization announcement number CN218815658U, the retractable safety fence structure includes a column assembly and a curtain assembly. When constructing a circular isolation belt, the operator pulls the free end of the curtain net and pulls the curtain net out of the exit slot. The rotating storage piece that stores the curtain net moves with it. After pulling it to the required length, the connector is inserted into the adjacent hollow column. In this way, the end-to-end connection is connected to construct a circular isolation belt. The operator rotates the rotating storage piece, and the rotating storage piece drives the curtain net to be bundled and stored. First, the retractable safety fence structure is only the size of a single column after being stored, reducing the occupied space. Second, the retractable safety fence structure has only one column, and the weight of the curtain net is relatively small, so that the overall weight of the retractable safety fence structure is smaller than that of the existing safety fence. Third, the hollow column can be set at different heights and can be applied to different ground surfaces. This patent is also a physical isolation, which is easy to be intruded by people and animals without human supervision and cannot be discovered and stopped in time. When the isolation is set up continuously over a long distance, the fence net will be blown away in the wind, and there is a risk of the device tipping over. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a road construction safety isolation alarm device, which can automatically alarm when moving objects such as people and animals enter the area, so that the on-site manager can stop them in time.
