[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1 to 4 The intelligent ventilation fan control device for linkage between the inside and outside of a tunnel in this embodiment includes a tunnel face 1 and a jet fan 2. A monitoring and control component is provided on the tunnel face 1, and an installation component is provided on the tunnel face 1.

[0023] Example 1: The monitoring and control component includes a cloth hanging trolley 15 installed inside the working face 1. A monitoring unit 3 is fixedly installed on the outside of the cloth hanging trolley 15. The monitoring unit 3 consists of a smoke detector, an oxygen saturation sensor, a temperature sensor, and a dust sensor.

[0024] A signal transmission unit 4 is installed on the outside of the jet fan 2. The signal transmission unit 4 consists of a wireless transmitting module, a wireless receiving module and a fan programmable controller. An execution unit is installed inside the working face 1. The execution unit includes a PLC information programming processor, an intermediate relay and a frequency converter. A remote communication module is also installed inside the working face 1 to facilitate the transmission of collected information to an external Internet of Things data platform, etc.

[0025] The working face 1 is equipped with a secondary lining trolley 5, and an installation column 6 is fixedly installed inside the working face 1. A horizontal plate 7 is fixedly installed on the front of the installation column 6, and an air quality detector 8 is placed on the top of the horizontal plate 7.

[0026] During the operation of the fan, the air quality detectors 8 prefabricated in each section of the duct cloth are used to monitor and compare the data. By comparing the preset normal wind loss ratio with the difference in the monitored data, the wind pressure difference of each section of the duct cloth is determined. Based on the actual wind pressure requirements at the construction site, the fan ventilation volume is automatically adjusted, and a remote communication alarm signal is given to remind the equipment management and maintenance personnel to maintain the abnormal ventilation section in a timely manner.

[0027] It should be noted that the intelligent ventilation fan control device that links the inside and outside of the tunnel, through the installation of monitoring and control components, helps to save personnel control and management costs and improve timeliness. It can save energy by adjusting the equipment speed in time and automatically switching the equipment on and off, thus avoiding energy consumption of the equipment. It can also reduce the wear and tear of the equipment itself and lower the equipment maintenance costs.

[0028] Specifically, the intelligent ventilation fan control device that links the inside and outside of the tunnel uses monitoring units 3 (smoke detectors, oxygen saturation sensors, temperature sensors, and dust sensors) installed on-site to collect environmental data. When the preset parameter thresholds of each sensor are reached, the sensors send a switching signal, which is transmitted to the receiving module via the signal transmission unit 4 and the remote wireless transmission module. The receiving module then outputs the switching signal to the fan control unit to control the fan's start / stop and speed adjustment. This timely adjustment of the equipment speed and automatic switching of the equipment avoids energy consumption and saves energy. It also reduces equipment wear and tear and lowers maintenance costs.

[0029] Example 2: Please refer to Figure 1 Based on Embodiment 1, an installation component is also provided on the working face 1. The installation component includes a fixing block 9 that is fixedly installed on both sides of the mounting column 6, and a compression spring 10 is fixedly installed inside each of the two fixing blocks 9.

[0030] Telescopic rods 11 are fixedly installed inside both fixed blocks 9. First mounting grooves are opened on opposite sides of both fixed blocks 9. Compression springs 10 and telescopic rods 11 are fixedly connected to fixed blocks 9 through the first mounting grooves.

[0031] The mounting assembly also includes a limiting clamp 12 fixedly mounted to the output ends of the two telescopic rods 11. There are several mounting posts 6. The telescopic rods 11 are located inside the compression springs 10. The opposite sides of the two compression springs 10 are fixedly connected to the limiting clamp 12.

[0032] A rotating rod 13 is rotatably mounted on the front of each of the two limiting clamps 12. A second mounting groove is opened on the front of each of the two limiting clamps 12. The rotating rod 13 is rotatably connected to the limiting clamp 12 through the second mounting groove. A positioning plate 14 is fixedly mounted on the front of each of the two rotating rods 13.

[0033] It should be noted that the intelligent ventilation fan control device that links the inside and outside of the tunnel, through the installation of installation components, allows for convenient and rapid disassembly and repair when the air quality detectors 8 installed at intervals inside the working face 1 are damaged, thereby improving the overall monitoring and control quality of the device.

[0034] Specifically, the intelligent ventilation control device that links the inside and outside of the tunnel can rotate the two positioning plates 14 180 degrees by rotating the rod 13 when the air quality detector 8 is damaged. This causes the positioning plates 14 to move away from the surface of the air quality detector 8, releasing the restriction on the air quality detector 8. Then, the two limiting clamps 12 are pulled in opposite directions, causing the compression spring 10 and the telescopic rod 11 to stretch, thereby releasing the restriction of the limiting clamps 12 on both sides of the air quality detector 8, making it easier for maintenance personnel to quickly disassemble the air quality detector 8 for repair.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) The intelligent ventilation fan control device that links the inside and outside of the tunnel is used by the monitoring unit 3 (smoke alarm, oxygen saturation sensor, temperature sensor and dust sensor) installed at the tunnel site to collect environmental data information at the construction site. When the preset parameter threshold of each sensor is reached, the sensor gives a switch signal. The signal is transmitted to the receiving module through the signal transmission unit 4 and the remote wireless transmission module. The receiving module outputs the switch signal to the fan control unit to control the fan to start and stop and adjust the gear. It can adjust the equipment gear and automatically switch the equipment to avoid energy consumption and reduce the wear and tear of the equipment and reduce the maintenance cost of the equipment.

[0037] (2) When the air quality detector 8 is damaged, the intelligent ventilation fan control device that links the inside and outside of the tunnel rotates the two positioning plates 14 by 180 degrees through the rotating rod 13, so that the positioning plates 14 are rotated away from the surface of the air quality detector 8, releasing the limitation on the air quality detector 8. Then, the two limiting clamps 12 are pulled in opposite directions, so that the compression spring 10 and the telescopic rod 11 are stretched, thereby releasing the limitation of the limiting clamps 12 on both sides of the air quality detector 8, making it easy for maintenance personnel to quickly disassemble the air quality detector 8 for repair.
