The device is convenient to adjust the position of the flowmeter on the long rod by embedding the second positioning buckle into the corresponding positioning hole. Through the design of the long rod and the debris block, the floating debris on the water can be redirected or collected by the debris block. The floating debris is pushed to both sides by the pointed cone part of the debris block, or the floating impurities are collected into the debris cavity. Thin floating debris will not affect the flow measurement of the flowmeter, and the stability is high.

A flow measuring device 3 is installed on the outer circumferential wall of the installation ring 207, a clamping component 4 is fixedly arranged on the inner circumferential wall of the installation ring 207, a connecting cylinder 5 is welded to the bottom of the vertical rod 1, and a lead fish 6 is threadedly connected to the bottom of the connecting cylinder 5. In the utility model, a staff member rotates the turning handle 202 to drive the worm 201 to rotate, thereby driving the worm wheel 203 to rotate, and then the lead screw 204 drives the moving block 205 to move. The installation ring 207 is moved to a required position through the connecting rod 206, which is convenient for adjusting the position of the flow measuring device 3 when the hydrological flow measurement suspension rod is underwater. The lead fish 6 is connected through the connecting cylinder 5. The lead fish 6 is a hydrological measurement instrument made of metal lead or a mixture of lead and iron, which has a certain weight and an elongated ratio and a streamlined shape.

[0029] Specifically, the clamping component 4 includes a groove 401, a spring 402 is fixedly arranged on the side wall of the groove 401, a clamping block 403 is fixedly arranged at one end of the spring 402, and a plurality of clamping grooves 404 are equidistantly arranged on the outer circumferential wall of the vertical rod 1. The clamping block 403 is driven to move by the resilience of the spring 402, so that the clamping block 403 is clamped into the inside of the clamping groove 404, which is convenient for making the installation ring 207 more stable, so as to fix the position of the flow measuring device 3 for hydrological flow measurement.

[0030] Furthermore, the clamping block 403 is hemispherical, and the size and position of the clamping block 403 match the size and position of the clamping groove 404. Through the hemispherical clamping block 403 that matches the size and position of the clamping groove 404, it is convenient for the clamping block 403 to be squeezed out of the clamping groove 404 when the installation ring 207 moves.

[0034] Working principle: When the device is required to perform hydrological flow measurement, the staff manually rotates the rotating handle 202 to drive the worm 201 to rotate, so that the worm gear 203 drives the lead screw 204 to rotate, and then the moving block 205 drives the mounting ring 207 to move. The flowmeter 3 is installed on the circumferential outer wall of the mounting ring 207. The connecting block 7 at the top of the lead fish 6 is screwed into the connecting cylinder 5, and the hydrological flow measurement suspension rod is placed in the water for flow measurement. When it is necessary to further adjust the position of the flowmeter 3, rotate the rotating handle 202 located at the top of the circumferential outer wall of the vertical rod 1.
