An installing seat 21 is fixedly disposed at one end of the driving shaft 2 positioned in the middle part of the die cavity of the circular disc casing 1, where a detection device is disposed on the installing seat 21.
    A hanging lug 13 is fixedly disposed on a side wall of the circular disc casing 1. An overground operator of a coal mine suspends the whole device of the present invention to an underground position of the coal mine at a specified height by tying and locking a rope onto the hanging lug 13. After the underground position of the coal mine at the specified height is reached, the driving shaft 2 is driven so that the detection device 5 positioned on the installing seat 21 in the storage cabin 11 rotates to the position of the open cabin 12, and the detection device is configured to detect surrounding gas.
    At an initial stage of the present invention, the detection device is positioned in the storage cabin 11. Only when the specified position is reached, the driving shaft 2 is driven to drive the detection device to move to the position of the open cabin 12 through the installing seat 21. In such a mode, the amount of underground dust adhered to the detection device in a process of hanging the whole device of the present invention to the underground position of the coal mine at the specified height is reduced, and the influence of interference of the dust adhesion amount on precision of the detection device is reduced.
    An underground switch is disposed on the detection device. The detection device includes a temperature sensor, a humidity sensor, a gas sensor, a carbon monoxide sensor and an oxygen gas sensor, where each of the temperature sensor, the humidity sensor, the gas sensor, the carbon monoxide sensor and the oxygen gas sensor is singly and electrically connected with the underground switch.
    The temperature sensor is configured to detect a temperature of an underground detection position of the coal mine in real time. The humidity sensor is configured to detect gas humidity in the underground detection position of the coal mine in real time. The gas sensor, the carbon monoxide sensor and the oxygen gas sensor are configured to detect mixed gas ingredients in the underground detection position of the coal mine in real time.
    The detection device transmits data information collected by the plurality of sensors to an overground switch through the underground switch, the overground switch receives the data information and then displays the data information, and the overground operator analyzes completeness of gas in the detection position of the device through displayed data.
    As shown in FIG. 3 and FIG. 4, in the present embodiment, a support strip 3 is fixedly disposed at one side of the circular disc casing 1. A support guide rail 31 is fixedly disposed on the support strip 3, where the support guide rail 31 is provided with a slide groove. A driving strip 32 sliding along the slide groove is disposed in the slide groove, where the driving strip 32 is in gas tight sealing with an inner wall of the slide groove through a sealing element. A rack 33 is disposed on the driving strip 32.
    A driving gear 21 is fixedly disposed at one end of the driving shaft 2 positioned at the outer side of the circular disc casing 1. The driving gear 21 and the rack 33 are engaged and connected.

    Each of the gas pump 34 and the electromagnetic valve is singly and electrically connected with the underground switch.
    In use, at an initial stage, the electromagnetic valve controls the gas outlet hole, so that the gas outlet hole is in an OFF state. When the driving shaft 2 needs to be driven so that the detection device positioned on the installing seat 21 in the storage cabin 11 rotates to the position of the open cabin 12, the overground operator transmits an instruction to the underground switch through the overground switch, and the gas pump 34 is enabled to start to work. The gas pump 34 inflates the lower end part of the cavity of the slide groove, so that the driving strip 32 moves. The moving driving strip 32 enables the rotating shaft to rotate through the driving gear 21. Further, the driving shaft 2 is enabled to rotate. The rotating driving shaft 2 rotates the detection device positioned on the installing seat 21 in the storage cabin 11 to the position of the open cabin 12, and at the moment, the gas pump 34 stops working.
    A reset spring 35 is disposed between the bottom end of the driving strip 32 and the bottom end of the cavity of the slide groove. The two ends of the reset spring 35 are respectively and fixedly disposed at the bottom end of the driving strip 32 and the bottom end of the cavity of the slide groove. When the gas pump 34 inflates the lower end part of the cavity of the slide groove, the reset spring 35 is in a stretched state.
    After the detection by the detection device is completed, the overground operator transmits an instruction to the underground switch through the overground switch, so that the electromagnetic valve opens the gas outlet hole. At the moment, the reset spring 35 resets, and the driving strip 32 1s driven to move, so that the detection device on the installing seat 21 is positioned in the storage cabin 11 again. In this period, excessive gas at the lower end part of the cavity of the slide groove is exhausted from the gas outlet hole.
    A dust suction device is disposed in a junction position of the open cabin 12 and the storage cabin 11. The dust suction device includes dust suction pipes 41 with a plurality of dust suction heads and a dust suction pump 42, where the dust suction pump 42 communicates with the dust suction pipes 41 through hoses. The dust suction pump 42 is fixedly disposed on the circular disc casing 1.
    The dust suction pump 42 is electrically connected with the underground switch.
    In use, and in a process that the detection device positioned on the installing seat 21 in the storage cabin 11 rotates to the open cabin 12, or in a process that the detection device on the installing seat 21 is positioned in the storage cabin 11 again, the overground operator transmits an instruction to the underground switch through the overground switch, so that the dust suction pump 42 is started. The started dust suction pump 42 performs dust suction on the passed detection device through the dust suction pipes 41, thus further reducing the influence of interference of the dust adhesion amount on precision of the detection device.
    In the present embodiment, the upper and lower ends of the circular disc casing 1 are fixedly provided with uniformly distributed contracting rods 5. The top ends of the contracting rods 5 are fixedly provided with buffer discs 6. A plurality of universal wheels 7 are disposed on each buffer disc 6.
