The inner side of the clamping plate 10 is in contact with the surface of the conveying pipe 3. By setting the clamping plate 10, the conveying pipe 3 can be supported and the stability of the conveying pipe 3 is improved.

[0021] The protective mechanism 2 includes a U-shaped frame 22. The left and right sides of the top of the U-shaped frame 22 are respectively connected to the bottom of the alarm 1 and the speaker 13 by bolts. The opposite sides of the inner cavity of the U-shaped frame 22 are respectively fixedly connected with a spring 24 and a damping block 23. The opposite sides of the spring 24 and the damping block 23 are connected to the outside of the box body 5 by bolts. The left and right sides of the inner cavity of the U-shaped frame 22 are connected with pulleys 21 by bolts. The top and bottom of the left and right sides of the box body 5 are provided with movable grooves 14 used to cooperate with the pulleys 21. By setting the pulleys 21 and the movable grooves 14, the up and down movement of the U-shaped frame 22 can be limited to protect the box body 5.

[0022] A switch 15 is fixedly embedded on the front surface of the box body 5. The output ends of the switch 15 and the gas detector 12 are electrically connected to the input ends of the alarm 1, the solenoid valve 1 4, the exhaust fan 7, the solenoid valve 2 8 and the speaker 13. By setting the switch 15, the device can be manually closed, which is more convenient to use.

By setting the observation window 16, the data on the internal gas detector 12 can be observed, and the observation is more convenient.

[0024] The gas detector 12 is an instrument tool for detecting gas leakage concentration, including: portable gas detector 12, handheld gas detector 12, fixed gas detector 12, online gas detector 12, etc., which mainly uses gas sensors to detect the types of gases present in the environment. Gas sensors are sensors used to detect the composition and content of gases. The gas detector 12 can detect hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases. It is widely used in on-site detection in various places such as petrochemical, coal, metallurgy, chemical industry, municipal gas, environmental monitoring, etc., and can meet the measurement needs of special occasions; it can detect gas concentration or leakage in tunnels, pipelines, tanks, confined spaces, etc.

[0025] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulics or pneumatics. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used are check valves, safety valves, directional control valves, speed regulating valves, etc.

[0026] During use, gas leakage occurs, and the gas flowing in the delivery pipe 3 and the detection tube 11 is reduced. After the gas detector 12 detects that the gas content is abnormal, the solenoid valve 4 is automatically closed to close the delivery pipe 3, and the alarm light 1, exhaust fan 7, solenoid valve 28 and speaker 13 are automatically turned on. The exhaust fan 7 draws out the airflow leaked inside the box body 5 and discharges it into other containers through the exhaust hole 17 to seal the airflow. If a collision occurs, the U-shaped frame 22 is squeezed inward, causing the spring 24 and the damping block 23 to be squeezed inward, driving the pulleys 21 on both sides to move in the movable groove 14 to protect the box body 5.

[0027] To sum up: the airflow detection alarm device used for workshop water, electricity and gas installation, through the coordinated use of pulley 21, U-shaped frame 22, damping block 23, spring 24 and movable groove 14, solves the problem that the device cannot be protected, making the detection device easily damaged when encountering a collision, causing damage to internal components and lack of safety.
