Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 As shown, a device for measuring flow velocity and water level includes a displacement float block 1, a first U-shaped tube 2, a second U-shaped tube 3, a fan-shaped float block 5, a plastic circular frame 7, a motor 8, a timing module 9, a controller 11, a guide rod 16, an inclined panel 18, a photovoltaic panel 19, and a water level measuring instrument 20. Displacement float blocks 1 are slidably inserted through the middle section of the first U-shaped tube 2 and the middle section of the second U-shaped tube 3. Iron ring plates 101 are fixedly installed on both ends of the displacement float block 1. Circular blocks 4 are fixedly installed at both ends of the middle section of the first U-shaped tube 2 and the middle section of the second U-shaped tube 3. A ring electromagnet 401 and an inductive switch module 402 are respectively fixedly installed on opposite sides of two circular blocks 4 on the same U-shaped tube. Four fan-shaped float blocks 5 are provided, each installed at the bottom of a plastic circular plate 6. Each fan-shaped float block 5 is a hollow plastic structure, enhancing the buoyancy required for the entire device to float on the liquid surface. The shaft end located in the middle of the plastic circular plate 6 is connected to the output shaft of the motor 8 located inside the plastic circular frame 7. The timing module 9, the wireless data transmission module 10 and the controller 11 are installed around the plastic circular frame 7. The end detection element 21 of the water level measuring instrument connected to the water level measuring instrument 20 is installed at the middle position of the bottom of the plastic circular plate 6.

[0020] Combination Figure 2 and Figure 3As shown, the first U-shaped tube 2 and the second U-shaped tube 3 form a cross shape, and both ends of the first U-shaped tube 2 and the second U-shaped tube 3 are fixedly installed at the bottom of the plastic circular plate 6 so that the first U-shaped tube 2 and the second U-shaped tube 3 connected to the motor 8 can be rotated by 90° to achieve the effect of positioning the displacement floating block 1 at the initial displacement position in the water-facing direction.

[0021] The annular electromagnet 401 and the inductive switch module 402 in the same group are electrically connected to the controller 11 through wires. The controller 11 controls the start and stop of the annular electromagnet 401 and receives signals from the inductive switch module 402, which is beneficial for releasing the displacement floating block 1 that can move with the flow and obtaining the displacement time during the flow velocity measurement process.

[0022] like Figure 1 As shown, side strips 12 are vertically installed on both sides of the plastic circular frame 7, and circular holes 13 are opened at the outer ends of the side strips 12. A guide rod 16 passes through the circular hole 13, and the top end of the guide rod 16 is threaded into the corresponding screw hole 17. A limit block 14 is installed at the bottom end of the guide rod 16. By cooperating with the corresponding circular holes 13 through the rectangular distribution of the guide rods 16, the whole can only move up and down with the help of buoyancy, which also provides feasibility for detecting water level changes.

[0023] Combination Figure 2 As shown, there are two sets of screw holes 17, and the two sets of screw holes 17 are symmetrically opened on the top of the strip plate 15. The screw holes 17 are in pairs, and the screw holes 17 are used to connect the threaded part on the guide rod 16 to achieve the effect of fixing.

[0024] The top of the strip plate 15 is fixedly connected to the water level measuring instrument 20, and a sloping panel 18 is fixedly installed on the middle of one side of the strip plate 15. A photovoltaic panel 19 is installed on the sloping surface of the sloping panel 18, so that the photovoltaic panel 19 can provide power.

[0025] The inner diameter of the channel in the middle of the displacement float block 1 is larger than the outer diameter of the first U-shaped tube 2 and the outer diameter of the second U-shaped tube 3, so as to prevent the displacement float block 1 from being affected.

[0026] Working principle:

[0027] The annular electromagnet 401 on one of the circular blocks 4 in the same group releases its magnetic attraction to the iron ring 101 at the end of the displacement float block 1. At the same time, under the action of the controller 11, the inductive switch module 402 at that location is turned on and the timing module 9 starts timing. Since the distance between the two circular blocks 4 at the middle of the first U-shaped tube 2 and the second U-shaped tube 3 is a fixed length, the displacement float block 1 moves to another circular block 4 in the same group in the direction of water flow. At the same time, another inductive switch module 402 in the same group contacts the corresponding end of the displacement float block 1, so that the other inductive switch module 402 turns off the timing module 9, thereby obtaining the displacement time of the distance from the initial point to the end point. Combined with the data obtained by the controller 11, the flow velocity can be finally obtained. By placing the end detection element 21 of the water level measuring instrument at the bottom of the plastic circular plate 6 connected by the fan-shaped float block 5, the end detection element 21 of the water level measuring instrument is immersed in the liquid, thereby realizing water level monitoring.

[0028] In summary, the advantages of this utility model compared with the prior art are that, by using the displacement float 1 within a set length range and the timing module 9 used for displacement timing, combined with the displacement linear guide structure and controller 11, the flow velocity of water can be measured. It is less affected by external factors and has high measurement data accuracy. The start and stop control of the annular electromagnets 401 distributed in the same group under the controller 11 is beneficial to control the fixed position of the displacement float 1 at the initial point of displacement movement. The first U-shaped tube 2 and the second U-shaped tube 3 distributed in a cross shape, as well as the various configurations of the displacement float 1, combined with the motor 8, keep the connected parts in a 90° rotation state to ensure the continuous measurement of flow velocity.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
