[0020] The following is combined with Figure 1-4 The utility model is further described.
[0021] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a river flow monitoring device, comprising: a U-shaped plate 1, a filter frame 3, a floating adjustment component, a distance measuring unit, a monitoring unit and a lifting drive unit.
[0022] In the specific technical solution, the filter frame 3 is rotatably connected to one end of the U-shaped plate 1. The filter frame 3 is used to filter garbage.

The outside of the U-shaped plate 1 is fixedly connected to a fixing seat 10. The axle rod 9 is rotatably connected to the fixing seat 10, so that the filter frame 3 can be rotatably installed.
[0023] In a further design, the floating adjustment assembly is arranged in the U-shaped plate 1;
[0024] Specifically, the floating adjustment assembly includes a guide rod 7 fixedly connected to the U-shaped plate 1 and a floating plate 8 penetrating the guide stem. The floating plate 8 is a foam plate or a hollow plastic plate for detecting the water level of the water flow.
[0025] Wherein, the distance measuring unit is fixedly connected to the top of the U-shaped plate 1;
[0026] Specifically, the ranging unit is a ranging sensor 4 fixedly connected to the top of the U-shaped plate 1. A controller is also fixedly connected to the outside of the U-shaped plate 1. The ranging sensor 4 is electrically coupled to the controller, and the controller is not marked in the accompanying drawings. The controller can also be set outside. The ranging sensor 4 is used to detect the height of the floating plate 8.
[0027] In addition, the monitoring unit is fixedly connected to the top of the U-shaped plate 1;

[0029] In a further design, in order to facilitate the cleaning of the garbage in the filter frame 3, a lifting drive unit is arranged outside the U-shaped plate 1 to drive the filter frame 3 to rotate.
[0030] Specifically, the lifting drive unit includes a rack 16 slidably mounted on the outside of the U-shaped plate 1 and a gear 15 rotatably connected to the top of the U-shaped plate 1. The outside of the U-shaped plate 1 is fixedly connected to a guide frame 17, and the rack 16 is slidably connected in the guide frame 17. The outside of the U-shaped plate 1 is also fixedly connected to a mounting seat 14, and a rotating rod 13 is rotatably connected in the mounting seat 14. The gear 15 is fixedly connected to the rotating rod 13, and the outsides of the rotating rod 13 and the shaft 9 are fixedly connected to a sprocket 11, and a chain 12 is transmission-connected between the two sprockets 11.

[0033] When in use, a narrower position in the river channel is selected, and then the U-shaped plate 1 is installed in the river channel, and the two ends of the U-shaped plate 1 are respectively in contact with the two sides of the river channel, and then under the action of the water flow, the floating plate 8 will float upward, and then the distance between the floating plate 8 and the bottom of the U-shaped plate 1 can be calculated by detecting the rising height of the floating plate 8 through the distance measuring sensor 4. For example, the height of the U-shaped plate 1 is: h1, the width is g, and the rising height of the floating plate 8 is: h2, so the distance between the floating plate 8 and the bottom of the U-shaped plate 1 is: h1-h2, and then the speed of the water flow in the U-shaped plate 1 is monitored by the water flow velocity measuring radar 5, assuming it is K, so the water flow rate per unit time can be calculated, for example, the cross section A=g*(h1-h2) formed between the floating plate 8 and the U-shaped plate 1 is calculated, and then the water flow rate per unit time M=A*K.
[0034] So the water flow rate can be calculated.
[0035] The filter frame 3 is then moved back to the filter housing 3. The filter housing 3 is then moved back to the filter housing 3. The filter housing 3 is moved back to the filter housing 3. The filter housing 3 is then moved back to the filter housing 3. The filter housing 3 is then moved back to the filter housing 3.
