Description

Technical Field

[0001] The utility model belongs to the technical field of mine safety detection, and in particular relates to a fire point detection and fire extinguishing device for open-pit coal mines. Background Art

[0002] With the expansion of coal mining and the improvement of production levels, fires have become a major challenge in mine safety management. Therefore, research on fire point identification and fire extinguishing technologies is crucial for improving coal mine production safety, ensuring personnel safety, protecting mining resources, and reducing environmental pollution. The development of advanced fire point identification technologies and efficient fire extinguishing methods can help timely detect and control fires, reduce casualties and property losses, and promote the sustainable development of coal mines. Traditional fire monitoring methods often rely on manual inspections or regular patrols, which are inefficient and prone to omissions. To improve the efficiency and accuracy of fire monitoring, fire point identification technology has emerged.

[0003] Fire spot identification technology uses a variety of sensors, remote sensing technologies, and image processing methods to achieve real-time monitoring of coal mines and automatically identify fire hotspots. These technologies include infrared thermal imaging, microwave remote sensing, optical cameras, and video surveillance. These technologies enable round-the-clock, high-resolution monitoring of mining areas, quickly and accurately detecting fire sources and issuing timely alarms, providing crucial information for firefighting efforts. With the advancement of artificial intelligence and big data technologies, fire spot identification technology is also undergoing continuous innovation. For example, deep learning algorithms are being used to automatically identify and classify fire images, further improving the accuracy and efficiency of fire spot identification.

At this time, under the action of the booster pump, the internal dry powder is quickly sprayed out, thereby achieving the purpose of releasing dry powder to extinguish the fire.

[0024] In addition, in this embodiment, the flight system includes: a bracket 8, a wing arm 4, a control system 14, and an antenna 1; the wing arm 4 is installed in a circular array at the end of the fire extinguishing body, and the end of the wing arm 4 is fixedly installed with a wing; the upper end of the fire extinguishing body 16 is fixedly installed with the control system 14, and the antenna 1 is installed on both sides of the control system 14; the bracket 8 is symmetrically installed on both sides of the lower end of the fire extinguishing body 16; the entire device is supported by the provided bracket.

[0025] Example 2

[0026] In this embodiment, specifically, during a safety inspection of a mining area, an operator uses a control system 14 to plan an inspection route for the device, and the device transmits the received route to the control system 14 via the antenna 1. After receiving the route, the control system 14 drives the blade motor, and the device begins to take off.
