Description

Technical Field

[0001] This utility model belongs to the field of coal mining technology, specifically relating to a roadway isolation and warning device for coal mining. Background Technology

[0002] In coal mining, it is essential to protect the safety of miners. Different protective measures must be implemented depending on the location of the mining operation. Existing isolation devices are mostly plate-like spliced ​​structures. Connecting adjacent plates often involves using bolts to link them together. This method requires repeatedly tightening each bolt, resulting in low assembly efficiency and inconvenient disassembly. Furthermore, existing isolation devices generally only provide isolation, offering poor warning effects, especially in dimly lit environments, making workers prone to accidental contact and resulting in a low safety factor.

[0003] Therefore, it is necessary to design a new roadway isolation and warning device for coal mine development to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a roadway isolation and warning device for coal mine operations. The specific solution is as follows:

[0005] A roadway isolation and warning device for coal mines includes a baffle, a back plate on the rear side of the baffle, and multiple elastic rods connecting the baffle and the back plate. A reflective warning sticker is affixed to the front side of the baffle, and multiple red LEDs are arranged around the reflective warning sticker on the front side of the baffle. An infrared sensor and an audible and visual alarm are also located on the front side of the baffle. The infrared sensor, the audible and visual alarm, and the multiple red LEDs are all electrically connected to a controller located on the rear side of the baffle. Multiple brackets are provided on one side of the baffle, and each bracket has a rod. Multiple positioning frames, each corresponding to one of the brackets, are provided on the other side of the baffle, and each positioning frame has a hole corresponding to the rod. A mounting frame is located on the rear side of the back plate, and a support leg is hinged to the mounting frame.

[0006] Based on the above, the support leg includes a support cylinder, a support rod is screwed into the support cylinder, the top end of the support rod is provided with a connecting plate that is hinged to the mounting frame, and the bottom end of the support cylinder is provided with a tapered head.

[0007] Based on the above, a battery is also provided on the rear side of the baffle to power the entire device.

[0008] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0009] The coal mine roadway isolation and warning device provided by this utility model has a structural design that facilitates the assembly and disassembly of multiple isolation and warning devices, and also allows for easy adjustment of the tilt angle of the baffle. It not only has an isolation function, but also a warning and reminder function. In addition, the device has a good collision buffering effect. The structure is ingenious, practical and feature-rich.
