Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to an intelligent coal mining carbon dioxide fire extinguishing device. Background Technology

[0002] In coal mining, fire extinguishing devices are often needed to control sudden fires. Existing mine fire extinguishing devices have several drawbacks: First, the fuel oil inert gas generators themselves are not explosion-proof, posing a significant risk to underground fire extinguishing, and the gas composition is unstable with excessively high oxygen content. Second, nitrogen generators are bulky, have low gas production, are difficult to transport, and the low density of nitrogen makes them difficult to deliver underground. Third, carbon dioxide fire extinguishing devices require manual activation in actual use, and after a fire is detected, carbon dioxide can only be injected over a wide area, unable to be precisely and effectively extinguished at the fire location, resulting in poor fire extinguishing effects and increasing the danger of mining.

[0003] Currently, existing fire extinguishing devices used in coal mining present significant inconvenience when replacing carbon dioxide fire extinguishers, often requiring considerable time and impacting extinguishing efficiency and optimal extinguishing time. Manual use of carbon dioxide fire extinguishers lacks intelligence and poses safety hazards. Furthermore, the need for frequent movement of the fire extinguishing device during coal mining operations, coupled with roadside bumps, can cause the fire extinguishers inside to shake, further complicating safety. To address these issues, this paper proposes an intelligent carbon dioxide fire extinguishing device for coal mining. Utility Model Content

[0024] The intelligent coal mining carbon dioxide fire extinguishing device provided by this utility model includes a base 1, a cabinet 2 on top of the base 1, and protective plates 3 installed on both sides of the cabinet 2 for protection. An air outlet block 4 is installed on the top of the cabinet 2, with air outlets 12 on both sides of the front end of the air outlet block 4. A camera 15 is installed on the top of the air outlet block 4, a temperature sensor 16 is installed on one side of the camera 15, and a smoke detector 17 is installed on the other side of the camera 15.

[0025] The front end of the cabinet 2 has a slot, and the cabinet 2 is connected to the cover door 5 through the slot. The cover door 5 extends through the cabinet 2 and is equipped with a quick-release mechanism 6. The base 1 has casters installed around its bottom.

[0026] The cabinet 2 is equipped with a carbon dioxide cylinder 9. The gas outlet pipe of the carbon dioxide cylinder 9 is connected to the gas outlet block 4, which in turn connects to the gas outlet 12.

[0027] The quick-release mechanism 6 includes a knob 601 on the cover door. A rod 602 is mounted on the inner side of the knob 601. The rod 602 is inserted into the inner outer surface of the cover door 5 and movably sleeved with a sleeve block 603. A tension spring 604 connects the sleeve block 603 and the knob 601. The tension spring 604 is located outside the rod 602. The rod 602 extends to the inner top of the cabinet 2 and is fitted with an insert 605. A latch 7 is mounted on the inner side wall of the cabinet 2. The rod 602 is locked in place by the insert 605 and the latch 7, thereby enabling the quick opening and closing of the cover door 5.

[0028] Two trays 8 are installed at the bottom of the cabinet 2. Carbon dioxide cylinders 9 can be placed on the top of the trays 8. Several buffer springs 10 are installed between the trays 8 and the carbon dioxide cylinders 9 on both sides.
