[0036] Specific usage method and function of this embodiment: In the present invention, when in use, a group of support seats 103 are placed on the top of one side of the channel, and the positioning plate 104 at the bottom of the support seat 103 is made to fit against the side wall of the channel; then the cross column 101 is pulled to place another group of support seats 103 on the top of the other side of the channel, so that the other group of positioning plates 104 fit against the side wall of the channel; at the same time, by the cooperation between the ratchet wheel 204, the pawl 203 and the torsion spring member, the rotating shaft 105 can only rotate in one direction, and thus the cross column 101 and the measuring frame 1 are fixed above the channel; through the two cross columns 101, the toothed plate 102 and the connecting gear 106 move in opposite directions at the same time, and thus the measuring frame 1 is automatically adjusted to the middle position between the two groups of support seats 103, so that the measuring frame 1 is directly above the center of the U-shaped channel; then the measuring column 303 is pressed down so that the bottom of the measuring column 303 fits against the inner bottom of the channel; during the movement of the measuring column 303, the measuring column 303 drives the cross bar 402 to slide outwards through the fixing block 305 and the locking block 405. When the measuring column 303 stops sliding, the spring member drives the locking block 405 to reset through the cross bar 402, so that the hypotenuse of the locking block 405 fits against the hypotenuse of the fixing block 305, and thus the measuring column 303 is fixed. The depth of the channel can be observed through the scale bar 304 and the pointer 302; then the double-headed screw rod 602 is rotated, and the double-headed screw rod 602 drives the two clamping plates 605 to move outwards at the same time through the two sliding seats 604 and the slide rail 603, so that the clamping plates 605 no longer clamp the guiding vertical rod 502; thus, the measuring floating plate 505 floats on the water surface; the infrared ranging probe 506 and the ranging plate 508 can measure the distance between the measuring floating plate 505 and the water surface and the bottom of the measuring frame 1. Subtracting the distance from the top of the measuring floating plate 505 to the bottom of the measuring frame 1 from the channel depth can obtain the water level; the flow velocity detection probe 507 can detect the flow velocity of the water flow inside the channel; the flow velocity detection probe 507 and the infrared ranging probe 506 respectively transmit the water flow velocity signal and the water level to the receiving terminal through the remote transmission module 108, which is beneficial for the staff to view in real time.
