The working principle is as follows: when the utility model is used, firstly, the device is pushed to the side of the fan to be detected, when the detected fan is at the bottom of the installation height, as shown in figure 1, the funnel-shaped cylinder 27 is aligned with the air outlet of the fan, the funnel-shaped cylinder 27 can effectively collect the wind force blown out from the air outlet of the fan and transmit the wind force to the windmill 30 arranged in the funnel-shaped cylinder, because the first rotating shaft 29 is rotatably connected with the second cylinder 28, and the first rotating shaft 29 is also rotatably connected with the square rod 11 through the first rotating block 15, so that when the fan operates normally, when the fan pushes the windmill 30, the windmill 30 rotates through the first rotating shaft 29, whether the fan operates can be visually detected, when the wind quantity of the fan to be detected is the same as the qualified wind quantity of the fan, after the rotating speed of the windmill 30 is uniform, the bottom end of the L-shaped pull rod 34 is held by one hand, the positioning bolt 35 is unscrewed, therefore, the sleeve 12 slides upwards under the action of the spring 13, so that the sleeve 12 can slowly move upwards by manually pulling the L-shaped pull rod 34, when the sleeve 12 moves upwards, the fixing block 16 drives the fluted disc 19 to ascend together until the fluted disc 19 is meshed with the gear 33, at this time, the gear 33 drives the fluted disc 19 to rotate together as the gear 33 rotates along with the first rotating shaft 29, the timing is started at the moment when the fluted disc 19 rotates, and the number of the first pointer 26 pointing to the fluted disc 19 scale is recorded, so that the rotating distance of the fluted disc 19 in a certain time can be recorded, and then the recorded data is compared with the rotating distance of the fluted disc 19 by a qualified fan in the same time, so that whether the air volume of the fan to be measured is qualified can be effectively compared, and whether the fan to be measured is in fault can be effectively detected. If the detected fan installation height is high, as shown in fig. 2, firstly, the sleeve 12 is pulled downwards by the L-shaped pull rod 34, so that the fluted disc 19 is not engaged with the gear 33 any more, then the positioning bolt 35 is tightened to fix the L-shaped pull rod 34, after the work is done, the output end of the hydraulic cylinder 3 is controlled to extend by the hydraulic station 4, so that the funnel-shaped cylinder 27 is aligned with the fan outlet installed at a high position, during the period that the output end of the hydraulic cylinder 3 extends, because the first sleeve 23 is slidably connected with the first square rod 24, the first square rod 24 cannot rise along with the output end of the hydraulic cylinder 3 at first beginning, until the first square rod 24 rises after the helical gear 25 at the top end of the first square rod 24 is engaged with the first helical gear 31, and similarly, when the funnel-shaped cylinder 27 is aligned with the fan outlet installed at a high position, the funnel-shaped cylinder 27 can effectively collect the wind force blown out from the fan outlet and transmit the wind force to the fan, and make windmill 30 and first pivot 29 rotate, first helical gear 31 of its side end department can drive first square pole 24 through helical gear 25 and rotate when first pivot 29 rotates, first square pole 24 can drive barrel 7 and rotate together when rotating, so bobbin 8 on barrel 7 can begin to coil the scale mark in tape 5, begin to time when the scale mark is beginning to be coiled to bobbin 8 that the inscription pointer 9 that begins to coil the scale mark points to the figure on the scale mark, so can record the length that bobbin 8 coiled the scale mark in certain time, then compare the data that record with qualified fan in the same time make bobbin 8 coil the length of scale mark, so can be effectual with the air quantity of the qualified fan that the required measurement is qualified, and then effectual detection needs whether the fan is out of order to measure the trouble.
