[0026] By adopting the above technical solution, the device can buffer the vibration generated by the vibrator 34 to a certain extent through the elastic deformation of the elastic rubber tube 31, thereby reducing the possibility of other structures being adversely affected and ensuring normal operation.

[0027] Specifically, the gas delivery assembly 33 includes an outer frame 331, a spring pin 332, a fixing ring 333 and a hose 334. The fixing ring 333 is installed below the connecting frame 32, and the outer frame 331 is arranged on the outer side of the fixing ring 333.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that: the drying and dehumidification device 6 includes a closed frame 61, an electric telescopic rod 62, a ventilation net 63, a silica gel desiccant 64 and a moving cylinder 66, a moving cylinder 66 is arranged above the fan channel assembly 4, and ventilation nets 63 are installed on the top and bottom of the moving cylinder 66. The inner side of the moving cylinder 66 and the position between the two ventilation nets 63 are filled with silica gel desiccant 64, and a closed frame 61 is installed above the device body 1 and on one side of the moving cylinder 66. The closed frame 61 and the moving cylinder 66 are connected by an electric telescopic rod 62.

[0032] By adopting the above technical solution, the device can perform a certain dehumidification treatment on the air through the cooperation of structures such as silica gel desiccant 64 and ventilation net 63 when necessary, so as to better meet the working needs in different situations.

[0033] Specifically, the drying and dehumidifying device 6 further includes a blocking block 65 , and the blocking block 65 is threadedly mounted on a side of the moving cylinder 66 away from the electric telescopic rod 62 .

[0034] By adopting the above technical solution, the staff can unscrew the blocking block 65 to replace the silica gel desiccant 64 when necessary, thereby reducing the difficulty of replacing the silica gel desiccant 64 and alleviating the labor burden of the staff.

[0035] When the present embodiment is used, when it is necessary to dehumidify the air, the staff starts the electric telescopic rod 62 in the drying and dehumidifying device 6, so that the moving cylinder 66 and other structures move to the top of the fan blade channel assembly 4, and the air discharged from the fan blade channel assembly 4 contacts the silica gel desiccant 64 between the two ventilation nets 63, and the moisture therein is absorbed by the silica gel desiccant 64, thereby dehumidifying the air; when dehumidification is not needed, the electric telescopic rod 62 is started, so that the moving cylinder 66 and other structures move to the inner side of the closed frame 61, and the air discharged from the fan blade channel assembly 4 no longer needs to pass through the moving cylinder 66 and other structures, and the two ventilation nets 63 are respectively closed by the inner top surface of the closed frame 61 and the outer top surface of the device body 1, thereby preventing the dehumidification work from being carried out, thereby better meeting the work needs in different situations.

[0036] The structure and principle of the device body 1, the dustproof net 2, the fan blade channel assembly 4 composed of the first air collecting port, the motor channel, the second air collecting port, the detection channel, the exhaust channel, the motor bracket, the drive motor and the fan blade, the detector assembly 5 composed of the first outer groove, the gas detector, the probe, the sensor and the fixing block, the buzzer assembly 7 composed of the second outer groove and the buzzer, and the installation assembly 8 composed of the installation plate and the screw rod have been disclosed in a gas leak detection alarm device disclosed in Chinese patent application No. 202020214781.5. The working principle is to first fix the device body through the installation plate and the screw rod. It is fixed on the wall of the gas use environment, and the power of the driving motor, gas detector and buzzer is turned on, so that the fan blades are driven by the driving motor to realize the exhaust work. The dustproof net can block impurities in the air from entering the inside of the device body. The air enters the first air collection port, the motor channel, the second air collection port and the detection channel through the dustproof net in turn, so that the air is detected by the sensor, probe and gas detector in the detection channel. When there is gas in the air, an alarm can be sounded through the buzzer to realize the alarm work, and the air in the detection channel is discharged to the outside of the device body through the exhaust channel. The above is the working process of the alarm device for gas leak detection.

[0037] The structure and principle of the vibrator 34 in the utility model have been disclosed in an easy-to-clean concrete mixing device disclosed in Chinese Patent Application No. 201821054815.8. Its working principle is composed of components such as springs, mass blocks, and motors. When the spring or mass block is subjected to external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0038] The working principle and use process of the utility model are as follows: when the gas station needs to use the device to detect gas leakage, the device body 1 is fixed in the working position through the two installation components 8, and then the fan blade channel component 4 is manipulated to suck the air filtered by the dustproof net 2 into the device body 1. The staff can start the vibrators 34 on both sides of the connecting frame 32 in the anti-blocking gas transmission device 3, thereby driving the connecting frame 32 and the dustproof net 2 therein to vibrate, thereby preventing the dustproof net 2 from being blocked. The elastic deformation of the elastic rubber tube 31 can buffer the vibration generated by the vibrator 34 to a certain extent. The detector component 5 detects the air, and then the air is discharged from the top of the fan blade channel component 4. When gas is detected, the buzzer component 7 alarms, thereby performing the detection work. When it is necessary to detect gas leakage at a distant location, the staff can install the outer frame 331 outside the fixing ring 333 under the connecting frame 32 through the two spring pins 332 in the gas transmission component 33 before work, and tighten the hose 33 The end of 4 is placed at the position that needs to be detected. When the fan blade channel component 4 is working, the air at the position that needs to be detected can pass through the hose 334 and other structures into the device body 1, and then be detected by the detector component 5; when the air needs to be dehumidified, the staff starts the electric telescopic rod 62 in the drying and dehumidification device 6, so that the moving cylinder 66 and other structures move to the top of the fan blade channel component 4, and the air discharged from the fan blade channel component 4 contacts the silica gel desiccant 64 between the two ventilation nets 63, and the moisture therein is absorbed by the silica gel desiccant 64, thereby dehumidifying the air. When dehumidification is not needed, the electric telescopic rod 62 is started, so that the moving cylinder 66 and other structures move to the inner side of the closed frame 61, and the air discharged from the fan blade channel component 4 does not need to pass through the moving cylinder 66 and other structures, and the two ventilation nets 63 are respectively closed by the inner top surface of the closed frame 61 and the outer top surface of the device body 1, thereby preventing the dehumidification work from being carried out, and better meeting the work needs in different situations.
