[0017] Reference Figures 1-6 A hydrological monitoring water flow velocity detection device includes a frame 2, a bracket 1 fixedly connected to one end of the frame 2, a counterweight base 6 fixedly connected to the lower end of the bracket 1 away from the frame 2, two fixed plates 8 fixedly connected to the frame 2, a connecting rod 7 inserted into the two fixed plates 8, and a snap-fit mechanism provided on each of the two fixed plates 8 for fixing the connecting rod 7. A radar water flow velocity meter 9 is fixedly connected to the lower end of the connecting rod 7. Support columns 4 are symmetrically fixedly connected to the frame 2. A tail wing 3 is set between the two support columns 4. The two sides of the tail wing 3 are fixedly connected to the support columns 4 through threaded shafts 5.
[0018] The upper surface curvature of the tail fin 3 is greater than that of the lower surface. Two threaded shafts 5 are fixedly connected to both sides of the tail fin 3. A top block is fixedly installed on the threaded shaft 5, and the top block abuts against the surface of the support column 4. The threaded shaft 5 passes through the support column 4, and a nut is threaded onto the end of the threaded shaft 5 away from the top block. The nuts and top blocks cooperate to clamp the threaded shaft 5 on both sides of the support column 4. The angle of the threaded shaft 5 is fixed by clamping, and the threaded shaft 5 is installed by clamping. Under the clamping force, the angle of the threaded shaft 5 can be adjusted, thereby adjusting the angle of the tail fin 3.
[0019] Reference Figure 4Frame 2 includes mutually perpendicular vertical shafts 17 and horizontal shafts 16. One end of the vertical shafts 17 and 16 is fixedly connected together, and the other end is fixedly connected together by support columns 4. Both the vertical shafts 17 and 16 are equipped with diagonal shafts. Two fixing plates 8 are fixedly connected to the upper and lower ends of the vertical shafts 17. Frame 2 is designed as a three-dimensional structure, with the vertical shafts 17, 16, and support columns 4 forming a triangular prism structure, increasing the overall structural stability and preventing swaying during use. Simultaneously, the diagonal shafts installed inside create multiple triangles within the frame. The triangular structure provides good stability and effectively resists pressure and shock absorption, maintaining stability when exposed to wind.
[0020] Reference Figure 6 The locking mechanism includes a locking block 13 and a locking shaft 11 fixedly connected together. Multiple locking slots 14 are equidistantly provided on the surfaces of both sides of the connecting rod 7. The locking shaft 11 passes through a mounting block 15, and the locking block 13 is locked into the locking slot 14. The locking shaft 11 is threaded onto the mounting block 15 via a knob sleeve 12. The connecting rod 7 is positioned between two mounting blocks 15. Multiple locking slots 14 are provided on both sides of the connecting rod 7 for locking. By rotating the knob sleeve 12 to tighten the locking shaft 11, the locking block 13 at one end of the locking shaft 11 is pressed and locked into the locking slot 14. Locking mechanisms are provided on both the upper and lower fixing plates 8, thereby achieving the fixing effect on the connecting rod 7, and the vertical position of the connecting rod 7 is adjustable.
[0021] Reference Figure 6 The connecting rod 7 has tapered edges on both its front and rear sides, and the edges of the connecting rod 7 are rounded. By making the front and rear of the connecting rod 7 tapered, the impact of wind on it is reduced, thus maintaining its stability. The rounded edges also help reduce wind resistance.
[0022] A guide plate 10 is rotatably connected to the rear of the radar current velocity meter 9. The guide plate 10 is fan-shaped. The guide plate 10 is rotatably installed at the rear of the radar current velocity meter 9. When encountering wind, it will rotate to consume wind power and reduce wind resistance.
[0023] Reference Figures 1-4 Before use, the height of the radar current velocity meter 9 is adjusted according to the river conditions. The connecting rod 7 is positioned relative to the fixed plate 8 by a snap-fit mechanism. The snap-fit block 13 in the snap-fit mechanism engages with the slots 14 at different positions on the surface of the connecting rod 7, which can change the height of the connecting rod 7 and thus change the height of the radar current velocity meter 9. Adjustments are made according to the detection requirements. The snap-fit shaft 11 is fixed by the knob sleeve 12. The snap-fit blocks 13 on both sides clamp the connecting rod 7 to achieve a fixed effect. According to the river environment, a bracket 1 of appropriate length is selected. The bracket 1 is then welded and fixed together with the frame 2. The side of the bracket 1 is triangular, which can better ensure the stability of the structure and connection.
[0024] During use, the radar current velocity meter 9 can directly detect the water flow speed facing the river and transmit the detected data to the terminal. The radar current velocity meter 9 is existing technology, and its working principle will not be explained in detail here. The angle of the tail fin 3 can also be adjusted according to specific needs. The threaded shaft 5 passes directly through the support column 4 and is then tightened by a nut to fix the angle. During the detection process, when encountering wind, the wind passes over the upper and lower surfaces of the tail fin 3. Under the action of fluid mechanics, the pressure on the upper surface of the tail fin 3 will be greater than the pressure on the lower surface of the tail fin 3. Under the action of force, the tail fin 3 will exert a downward force, which will be directly transmitted to the frame 2. This effectively prevents the whole structure from frequently swaying upward due to the wind. Keeping the whole structure downward helps to maintain stability and reduce swaying. By ensuring the stability of the overall structure, the service life of the equipment is improved.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
