A measuring mechanism 8 is installed at the upper end of the adjustment mechanism 7. A number of sensors 9 are installed on the upper surface of the fixing plate 1, and the sensors 9 are located on the right side of the clamping mechanism 2.
[0024] Working principle: Fixed plate 1 facilitates component installation; clamping mechanism 2 facilitates installation of the device on pipe 5; fixed rod 3 and positioning plate 4 facilitate fixing the device to the top wall, providing stability for the device installation and eliminating the need for pipe 5 to bear weight, adapting to more scenarios; connecting rod 6 facilitates installation and use of adjustment mechanism 7; adjustment mechanism 7 facilitates rotation and adjustment of measuring mechanism 8; sensor 9 facilitates the transmission of data measured by measuring mechanism 8.
[0025] Example 2, refer to Figure 3 and Figure 4This embodiment solves the problem that traditional methods for measuring large cross-section air volume usually require manual placement of the measuring mechanism inside the duct for periodic measurements. However, when measuring multiple channels, it is difficult to simultaneously place the measuring mechanism inside the duct for measurement, which consumes a lot of manpower and makes it difficult to measure accurately at the same time. The device for automatically measuring large cross-section air volume in multiple channels also includes a clamping mechanism 2, which includes a lower clamping ring 201 fixedly connected to a fixed plate 1. An upper clamping ring 202 is hinged to the upper right side of the lower clamping ring 201. A fixing block 203 is fixedly connected to the left side of the lower clamping ring 201 and the upper clamping ring 202. Fixing bolts 204 are inserted at both ends of the fixing block 203. The fixing block 203 has threaded holes that are adapted to the fixing bolts 204. The adjustment mechanism 7 includes a motor 701 mounted on the connecting rod 6. The power output end of the motor 701 is connected to a rotating shaft 702, and the rotating shaft 702 is rotatably mounted on the connecting rod 6.
