[0002] A gas detection and alarm device is a device used to detect and monitor the concentration of harmful gases in the air. If the concentration of harmful gases is detected to exceed a preset safety threshold, it will automatically trigger an alarm to emit a sound and light signal or other forms of alarm signals to prompt on-site workers to take necessary emergency measures. The gas detection and alarm device can be widely used in various places that need to monitor harmful gases, such as chemical plants, mines, oil fields, laboratories, hospitals, subways, etc. This device can timely detect the presence of harmful gases and issue alarms, making important contributions to ensuring production and protecting lives. However, the air inlet of the existing multi-channel mode gas detection and alarm control device is not protected by a dust-proof net cover. In the long term, dust in the air will affect the effect of the gas detector, and the air flow rate during gas detection cannot be controlled. Therefore, those skilled in the art provide a multi-channel mode gas detection and alarm control device to solve the problems raised in the above background technique. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multi-channel mode gas detection and alarm control device to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A multi-channel mode gas detection and alarm control device includes a gas detection main body. Heat dissipation grooves are provided at both the upper and lower ends of the gas detection main body. One end of the gas detection main body is fixedly connected with a control panel. A dust-proof net is provided at the other end of the gas detection main body. One end of the dust-proof net is fixedly connected with a gas inlet pipe. An air inlet fan is fixedly connected to the inner end of the gas inlet pipe. The other end of the gas inlet pipe is fixedly connected with multiple groups of multi-channel branch pipes. Gas detectors are fixedly connected to the outer ends of the multi-channel branch pipes.
[0006] Preferably, the other end of the multi-channel branch pipe is fixedly connected with an air outlet pipe. A clamping block is provided at one end of the dust-proof net.

[0008] By adopting the above technical solutions,
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: When the multi-channel mode gas detection and alarm control device needs to be used, the intake fan rotates. The intake fan sucks the outside air into the multi-channel mode gas detection and alarm control device, enabling it to quickly respond when there are gases to be detected in the air. The intake fan sucks the outside air through the dust-proof net into the gas inlet pipe. The dust-proof net can effectively filter the dust and impurities in the air, preventing them from entering the device interior and causing faults or damages. The dust-proof net can reduce the interference to the gas detection instrument. Without the dust-proof net, dust and impurities may enter the interior of the detection instrument, resulting in false measurements or deviations. Moreover, the dust-proof net can reduce the pollution inside the device, reduce the number of repairs, and extend the service life of the device, thereby improving the safety of the entire system. The air entering the gas inlet pipe enters the multi-channel branch pipes. Each multi-channel branch pipe has different gas detectors, enabling the multi-channel mode gas detection and alarm control device to simultaneously detect different gases in the air. The detected gases are discharged through the outlet pipe. The size of the outlet pipe can be controlled by adjusting the stopper on the outlet pipe, which affects the rate of air passing through the gas detector. When more accurate air detection is required, the servo motor is started. The servo motor drives the rotating disk to rotate. The rotating disk drives the fixed convex rod to rotate. The fixed convex rod drives the adjusting rod to move. One end of the adjusting rod rotates on the rotating rod, and the other end of the adjusting rod drives the stopper rod fixed on the stopper to move. By controlling the position of the stopper in the outlet pipe, the residence time of the air in the gas detector in the multi-channel branch pipe can be adjusted. The longer the residence time, the more accurate the detection by the gas detector, which can be controlled according to the intermediate requirements. When quick detection is needed, the stopper expands and contracts, and the outlet pipe becomes larger, allowing more air to be detected. When precise detection is needed, the stopper blocks part of the outlet pipe, and the outlet pipe becomes smaller, enabling more precise detection of the air. When the dust-proof net gets dirty, press down the adjusting block. The adjusting block drives the latch to move downward. The latch releases the dust-proof net. The fixing rod groove at the inner end of the latch moves on the fixing rod, and at the same time, the latch compresses the spring. When replacing the new dust-proof net, release the adjusting block, and the spring restores its elasticity to drive the latch to return to its position and latch the dust-proof net. When the gas detector detects the presence of excessive gases, the alarm light emits light, the buzzer makes a sound to remind the staff, the data display screen shows data information, and the control button controls and adjusts the data setting of the multi-channel mode gas detection and alarm control device.

[0016] The working principle of the utility model is as follows: When the multi-channel mode gas detection and alarm control device needs to be used, the intake fan rotates. The intake fan sucks the outside air into the multi-channel mode gas detection and alarm control device, enabling it to quickly respond when there are gases to be detected in the air. The intake fan sucks the outside air through the dust-proof net into the gas inlet pipe. The dust-proof net can effectively filter the dust and impurities in the air, preventing them from entering the device and causing faults or damage. The dust-proof net can reduce the interference of the gas detection instrument. Without the dust-proof net, dust and impurities may enter the inside of the detection instrument, resulting in false measurements or deviations. Moreover, the dust-proof net can reduce the internal pollution of the device, reduce the number of repairs, and extend the service life of the device, thereby improving the safety of the entire system. The air entering the gas inlet pipe enters the multi-channel branch pipes. Each multi-channel branch pipe has different gas detectors, enabling the multi-channel mode gas detection and alarm control device to detect different gases in the air simultaneously. The detected gas is discharged through the outlet pipe. The size of the outlet pipe can be controlled by adjusting the stopper on the outlet pipe, which affects the rate of air passing through the gas detector. When more accurate air detection is required, the servo motor is started. The servo motor drives the rotating disk to rotate, the rotating disk drives the fixed convex rod to rotate, and the fixed convex rod drives the adjusting rod to move. One end of the adjusting rod rotates on the rotating rod, and the other end of the adjusting rod drives the stopper rod fixed on the stopper to move. By controlling the position of the stopper in the outlet pipe, the residence time of the air in the gas detector in the multi-channel branch pipe can be adjusted. The longer the residence time, the more accurate the gas detector can detect, which can be controlled according to the intermediate requirements. When quick detection is needed, the stopper expands and contracts, the outlet pipe becomes larger, and more air is detected. When precise detection is required, the stopper blocks part of the outlet pipe, the outlet pipe becomes smaller, and the detected air is more accurate. When the dust-proof net gets dirty, press down the adjusting block. The adjusting block drives the clamping block to move downward. The clamping block releases the dust-proof net. The fixing rod groove at the inner end of the clamping block moves on the fixing rod, and at the same time, the clamping block compresses the spring. When replacing the new dust-proof net, release the adjusting block, and the spring restores its elasticity to drive the clamping block to return to its position and clamp the dust-proof net. When the gas detector detects the presence of excessive gases, the alarm light emits light, the buzzer makes a sound to remind the staff, the data display screen shows the data information, and the control button controls and adjusts the data setting of the multi-channel mode gas detection and alarm control device.
