Referring to fig. 5, lengths of the sleeve 308 and the connecting rod 319 are equal to a distance between the support plate 306 and the bottom plate 334, and two ends of the first extension spring 303 are fixed to a bottom of the bottom plate 334 and a top of the support plate 306 respectively.

In this embodiment, when the structural support board 306 is moved to the highest position, the limiting post 317 is located below the first trapezoidal clamping block 321 at the lowest position, so that the limiting post 317 limits the connecting rod 319 through the first trapezoidal clamping block 321.

The working principle of the utility model is as follows: when the device is used, the flow rate detector 315 can be stably inserted into water through external positioning equipment, at the moment, water flows through the flow rate detector 315, so that the flow rate of water at the position can be detected through the flow rate detector 315, then the support plate 306 can drive the U-shaped connecting frame 327 to move through pulling the pull rod 307, the rack 313 can drive the spur gear 330 to rotate through the movement of the pull rod 307, the spur gear 330 can drive the second transmission bevel gear 312 to rotate through the first transmission bevel gear 311 when rotating, the worm 302 can rotate through the second transmission bevel gear 312 when rotating, the worm 302 can drive the worm gear 301 to rotate, the worm gear 301 can drive the flow rate detector 315 to swing through the connecting column 314, the limit post 317 is extruded by the inclined plane at one end of the first trapezoid clamping block 321 in the process, in this way, the limit post 317 is extruded to one end of the first trapezoid clamping block 321, in this process, the push rod 326 pulls the third expansion spring 323 to stretch along with the movement of the limit post 317, when one end of the first trapezoid clamping block 321 is separated from the limit post 317, the limit post 317 moves under the restoring force of the third expansion spring 323 to the lower part of the first trapezoid clamping block 321, so that the connecting rod 319 can be limited by the limit post 317, meanwhile, the outside air enters the sleeve 308 through the air hole 331 under the movement of the piston plate 332, the flow velocity detector 315 can detect the flow velocity of water at different positions by intermittently pulling the pull rod 307, thereby increasing the detection range of the device, and simultaneously improving the accuracy of detection data, when the detection is completed, the push rod 326 can be pulled, so that the push rod 326 drives the limit post 317 to move, thereby the limit post 317 moves out of the lower part of the first trapezoid clamping block 321, simultaneously, the third expansion spring 323 is stretched, then the push rod 326 is pulled continuously to enable the limit groove 318 to retract into the guide block 322, when the limit groove 318 is aligned with one end of the rectangular inserting rod 325, one end of the rectangular inserting rod 325 is buckled into the limit groove 318 under the action of the second expansion spring 316 due to the fact that shielding is lost, so as to limit the push rod 326 and prevent the push rod 326 from recovering under the action of the third expansion spring 323, at the moment, the first trapezoid clamping block 321 at one end of the connecting rod 319 loses limit, so that the connecting rod 319 moves downwards under the action of the first expansion spring 303, when the pull rod 307 recovers under the action of the first expansion spring 303, the pull rod 307 can extrude air in the sleeve 308 through the piston plate 332, and the diameter of the air hole 331 is smaller than that of the sleeve 308, so that gas in the sleeve 308 can be extruded slowly, so that the pull rod 307 is slowly restored, the pull rod 307 is prevented from being damaged due to larger collision with the support frame 304 caused by rapid restoration under the limit losing effect, the service life of the device is prolonged, when the connecting rod 319 moves to the lowest position, the second trapezoid clamping block 324 at the bottom of the L-shaped connecting plate 305 is inserted into the inner side of the U-shaped clamping block 320, the inclined plane at one side of the second trapezoid clamping block 324 can squeeze the U-shaped clamping block 320, the U-shaped clamping block 320 moves along the inclined plane at one side of the second trapezoid clamping block 324 along with the downward movement of the second trapezoid clamping block 324, the rectangular inserting rod 325 is pulled by the U-shaped clamping block 320 to move, the rectangular inserting rod 325 is separated from the limit groove 318, the push rod 326 is restored under the effect of the third telescopic spring 323, the limit column 317 is moved to the lower side of the first trapezoid clamping block 321 again, this will enable the stop post 317 to stop the connecting rod 319 again, and also enable the flow rate detector 315 to rotate to the initial position, which is convenient for the use of the subsequent equipment.
