Description

Technical Field

[0001] This utility model relates to the technical field of methane alarm devices, specifically a methane alarm device installation device for mining. Background Technology

[0002] As a major coal-producing country in the world, my country consistently ranks among the world's top producers. With vast amounts of coal resources buried deep underground, mine mining has become the primary method of extraction. However, underground working conditions are complex and fraught with danger, posing a significant threat to the lives of coal miners. Statistics show that numerous coal mine accidents occur in my country every year, each accompanied by tragic casualties and enormous economic losses, bringing indelible pain to countless families.

[0003] Under the existing technological system, methane detection alarm devices are diverse. Based on the different mounting methods, they can be broadly divided into handheld methane alarms and fixed-installation methane alarms. Fixed-installation methane alarms are equipped with a main unit chassis. Currently, the most common mounting method for this main unit chassis is to use anchor screws to directly mount it against the wall.

[0004] However, in actual use, this installation method for the main unit of the methane alarm has gradually revealed many drawbacks. Since the main unit is fixed to the wall, its installation height is difficult to change once determined. When the main unit is installed at a high position, the lack of an adjustable installation angle makes it difficult for staff to clearly observe the actual detection situation, undoubtedly causing inconvenience to real-time methane concentration monitoring. On the other hand, installing the main unit at an easily observable height inevitably occupies space in the mine passageway, affecting normal passage and operations within the mine. Furthermore, the main unit is highly susceptible to accidental collisions with transported equipment within the mine, leading to equipment damage and increasing maintenance and replacement costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a methane alarm installation device for mining, including an installation housing 1 and a fixing plate 2. The fixing plate 2 is fixedly connected to the side of the installation housing 1. An adjustment unit and a fixing unit are installed inside the installation housing 1. The adjustment unit is installed on the outside of the installation housing 1, and the fixing unit is installed on the inside of the installation housing 1.

[0024] The fixing unit includes a fixing housing 5, which is located inside the mounting housing 1. A fixing block 6 is fixedly connected to the bottom of the fixing housing 5. A threaded rod 7 is movably connected inside the fixing block 6. A knob 8 is fixedly connected to the side of the threaded rod 7. A movable block 9 is movably connected to the outer surface of the threaded rod 7. A slide rail 10 is fixedly connected to the bottom of the fixing housing 5.

A connecting plate 18 is fixedly connected to the bottom of the fixed housing 5. A transmission groove 19 is provided inside the connecting plate 18. By installing the adjustment unit and then activating the electric telescopic component 14, the electric telescopic component 14 pushes the connecting block 16 to move inside the movable groove 15. This causes the connecting rod 17 to move inside the transmission groove 19, thereby causing the fixed housing 5 to rotate around the central shaft 4, thus rotating the methane alarm panel to an angle that is easy to observe.

[0028] The inner side of the central shaft 4 is fixedly connected to the fixed housing 5.

[0029] The housing 1 is equipped with a ventilation fan 20, and the inner side of the fixed housing 5 is provided with a ventilator 21. By activating the ventilation fan 20, the methane alarm can be cooled in conjunction with the ventilator 21.

[0030] The fixing plate 2 has a threaded hole 3 inside, so that the device can be fixedly installed through the threaded hole 3.
