DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] In order to solve the technical problem that the radar water level gauge is easily affected by airflow and shakes, affecting the monitoring accuracy, as shown in Figures 1-6 and Figures 13-14 , the following preferred technical solutions are provided:

The radar water level gauge 7 is installed at multiple positions upstream and downstream respectively. The water level difference is monitored by calculating the difference between the upstream and downstream water level monitoring data. The angle compensation assembly 6 can adjust the monitoring angle of the radar water level gauge 7. The bottom of the support assembly 2 is provided with a detection assembly 8, which can detect the height offset and angle deviation data in real time. The detection assembly 8 is connected with the radar water level gauge 7.

[0041] In strong wind weather, the airflow makes the fixed rod 1 and the support assembly 2 sway, and then drives the radar water level gauge 7 to sway. At this time, the detection assembly 8 detects that the height and angle of the radar water level gauge 7 deviate from the preset value. At this time, the second connecting assembly 5 is connected with the driving assembly 3. The driving assembly 3 drives the second connecting assembly 5 and the radar water level gauge 7 to rise and fall, and cooperates with the real-time detection of the detection assembly 8. During the downward swaying of the fixed rod 1 and the support assembly 2, the second connecting assembly 5 and the radar water level gauge 7 rise. During the upward swaying of the fixed rod 1 and the support assembly 2, the second connecting assembly 5 and the radar water level gauge 7 descend. The use height of the radar water level gauge 7 is conveniently adjusted dynamically. The monitoring height of the radar water level gauge 7 is always maintained at a height within the allowable error range. At the same time, through the cooperation of the angle compensation assembly 6 and the real-time detection of the detection assembly 8, the monitoring angle of the radar water level gauge 7 is dynamically adjusted. The monitoring angle of the radar water level gauge 7 is always maintained at an angle within the allowable error range. Thus, the interference of airflow swaying on monitoring is offset. The airflow does not affect the monitoring accuracy in strong wind weather. The monitoring accuracy is conveniently improved. The bottom of the support assembly 2 is provided with a rotating assembly 9, which is connected with the first connecting assembly 4. Figure 1 、 Figure 8 and Figures 10-11 As shown, the bottom of the rotating assembly 9 is provided with a filter cylinder 10. The lower half of the filter cylinder 10 enters the river water. It can block waterweeds and garbage and other impurities from entering the monitoring range of the radar water level gauge 7, avoiding the interference of impurities with the emission and reception of radar signals. At the same time, the bottom surface of the filter cylinder 10 is far away from the riverbed, which can conveniently avoid the adhesion of soft mud. The filter cylinder 10 is made of a material with poor reflectivity, so as to avoid the reflection, scattering and diffraction phenomena during the monitoring of the radar water level gauge 7. At the same time, the filter cylinder 10 is provided with a protective coating to avoid aging and damage caused by long-term placement in the river water, thereby prolonging the service life. At the same time, the effective protection range of the filter cylinder 10 is greater than the monitoring area of the radar water level gauge 7. The filter cylinder 10 is provided with a crushing assembly 20, which can crush the waterweeds growing inside the filter cylinder 10, thereby avoiding affecting the monitoring of the radar water level gauge 7.

[0042] In use, although the bottom surface of the filter cylinder 10 is far away from the riverbed, part of the water grass will stay near the filter cylinder 10 and grow through the outer periphery of the filter cylinder 10 into the inside of the filter cylinder 10, thereby blocking the monitoring path of the radar water level gauge 7 and affecting the monitoring of the radar water level gauge 7. At this time, the first connecting assembly 4 is connected with the driving assembly 3 through the detection of the crushing assembly 20 that the water grass blocks the monitoring path, and the first connecting assembly 4 is lifted through the driving assembly 3, thereby driving the rotating assembly 9 and the filter cylinder 10 to lift and rotate at the same time, so that the crushing assembly 20 forms a spiral three-dimensional motion track, which covers the full height range of the filter cylinder 10 and expands the crushing area. At the same time, the synchronous action of rotary cutting and lifting pulling facilitates the efficient crushing of the internal water grass without dead angle, ensures the complete removal of the water grass, and avoids affecting the monitoring of the radar water level gauge 7.

[0045] As shown in Figures 1-4 and Figure 6 , the first connecting assembly 4 includes a U-shaped sliding frame 41 slidingly connected in the fixed frame 31, two first sliding blocks 42 slidingly connected in the U-shaped sliding frame 41, a first spring 43 fixedly connected on one side of each of the two first sliding blocks 42, and the other end of the first spring 43 is fixedly connected with the inner wall of the U-shaped sliding frame 41. A first electromagnet 44 is mounted on the inner wall of the U-shaped sliding frame 41, and a first magnet block 45 is fixedly connected on one side of each of the two first sliding blocks 42.

[0046] As shown in Figure 3 , Figure 5 and Figure 13As shown, the second connecting assembly 5 comprises a sliding plate 51 slidably connected in the fixed frame 31, two second sliding blocks 52 are slidably connected in the sliding plate 51, the second sliding blocks 52 are fixedly connected with second springs 53 on one side, the other end of the second springs 53 is fixedly connected with the inner wall of the sliding plate 51, a second electromagnet 54 is installed on the inner wall of the sliding plate 51, the second sliding blocks 52 are fixedly connected with second magnet blocks 55 on one side, the second sliding blocks 52 are fixedly connected with two sliding rods 56 on one side, two connecting grooves 57 are formed in the inner wall of the fixed frame 31, the sliding rods 56 are connected with the connecting grooves 57, and the sliding rods 56 are always connected with the connecting grooves 57 in the normal state, so that the monitoring position of the radar water level gauge 7 can be fixed.

[0047] As shown in Figure 3 , Figure 5 and Figures 13-14 , the angle compensation assembly 6 comprises two vertical plates 61 fixedly connected at the bottom of the sliding plate 51, a first support ring 62 is fixedly connected at the bottom of the vertical plates 61, a first servo motor 63 is installed on the outer wall of the first support ring 62, two first rotating shafts 64 are rotatably connected in the first support ring 62, the output end of the first servo motor 63 is fixedly connected with the first rotating shafts 64, a second support ring 65 is fixedly connected at one end of the first rotating shafts 64, a second servo motor 66 is installed on the outer wall of the second support ring 65, two second rotating shafts 67 are rotatably connected in the second support ring 65, the output end of the second servo motor 66 is fixedly connected with the second rotating shafts 67, and a support seat 68 is fixedly connected at one end of the second rotating shafts 67, and the radar water level gauge 7 is installed on one side of the support seat 68.

[0048] As shown in Figure 3 , Figures 5-6 and Figure 13As shown, the detection assembly 8 comprises a first inclination sensor 81 mounted on the bottom of the horizontal plate 22, which can detect the angle deviation of the fixed rod 1 and the horizontal plate 22 caused by air flow and other factors, monitor the angle deviation data, and provide a reference for subsequent adjustment of the height of the radar water level gauge 7. The top of the radar water level gauge 7 is provided with a second inclination sensor 82, which is a double-axis inclination sensor. The second inclination sensor 82 can collect the detection angle deviation data of the radar water level gauge 7, cooperate with the angle compensation assembly 6 to dynamically adjust the angle of the radar water level gauge 7, and ensure that it is always within the allowable error range, thereby improving the monitoring effect of the radar water level gauge 7. When the fixed rod 1 and the support assembly 2 are installed and fixed and in a stable state, the first inclination sensor 81 is calibrated by the controller 21. At this time, the controller 21 records the initial angle data of the first inclination sensor 81 when the horizontal plate 22 is in a horizontal state, sets this data as the preset reference value of the angle deviation of the fixed rod 1 and the horizontal plate 22, and provides a reference for the height adjustment of the radar water level gauge 7.

After the radar water level gauge 7 is adjusted to the preset initial monitoring angle by the angle compensation assembly 6, the second inclination sensor 82 is calibrated by the controller 21, and the current angle value of the second inclination sensor 82 is recorded as the preset reference value of the monitoring angle of the radar water level gauge 7. The range is set by the controller 21, and this range is set as the angle error allowable range.

[0049] In windy weather, the airflow makes the fixed rod 1 and the cross plate 22 sway, and then drives the radar water level gauge 7 to sway, at this time, the height and angle of the radar water level gauge 7 deviate from the preset value are detected through the first inclination sensor 81 and the second inclination sensor 82, at this time, the second electromagnet 54 repels the second magnet block 55 through the controller 21, drives the two second sliding blocks 52 and the sliding rod 56 to slide in the fixed frame 31, makes the sliding rod 56 gradually cancel the connection with the connecting groove 57, and extrudes the second spring 53, at the same time, the second sliding block 52 is connected with the second clamping groove 35, the sliding plate 51 and the radar water level gauge 7 are driven to rise and fall through the electric push rod 33, and the real-time detection of the first inclination sensor 81 is cooperated, so that the sliding plate 51 and the radar water level gauge 7 are lifted during the downward swaying of the fixed rod 1 and the cross plate 22, and the sliding plate 51 and the radar water level gauge 7 are lowered during the upward swaying of the fixed rod 1 and the cross plate 22, the use height of the radar water level gauge 7 is conveniently adjusted dynamically, the monitoring height of the radar water level gauge 7 is always maintained at a height within the allowable error range, at the same time, through the real-time detection of the second inclination sensor 82, when the angle of the radar water level gauge 7 changes, the first rotating shaft 64 and the second supporting ring 65 are driven to rotate through the first servo motor 63, the second rotating shaft 67, the supporting seat 68 and the radar water level gauge 7 are driven to rotate through the second servo motor 66, the monitoring angle of the radar water level gauge 7 is dynamically adjusted, the monitoring angle of the radar water level gauge 7 is always maintained within the allowable error range, so as to offset the interference of airflow swaying on monitoring, avoid the influence of airflow on monitoring precision in windy weather, and conveniently improve the monitoring accuracy.

[0050] In order to solve the technical problem that the garbage and waterweeds in the water environment affect the normal monitoring of the radar water level gauge, as shown in Figures 1-3 and Figures 7-12 , the following preferred technical scheme is provided:

[0051] As shown in Figures 1-3 and Figures 7-10 , the rotating assembly 9 comprises a sleeve 91 fixedly connected to the bottom of the cross plate 22, a limiting ring 92 fixedly connected to the bottom of the U-shaped sliding frame 41, a connecting ring 93 rotatably connected in the limiting ring 92, two vertical rods 94 oppositely fixedly connected to the bottom of the connecting ring 93, a positioning block 95 fixedly connected to one side of each of the two vertical rods 94, and a spiral groove 96 formed in the sleeve 91 and slidably connected with the positioning block 95.

The alarm is prior art, which will not be described in detail here. The infrared sensors 201 are waterproof to avoid the intrusion of river water and affect the use. The infrared sensors 201 can detect whether the water grass grows inside the filter cylinder 10 and blocks the monitoring path of the radar water level meter 7. A plurality of blades 202 are fixedly connected to the bottom of the inner wall of the filter cylinder 10.

At this time, the infrared sensors 201 detect that the water grass blocks the monitoring path, and the controller 21 causes the first electromagnet 44 to repel the first magnet block 45, drives the first sliding block 42 to slide in the U-shaped sliding frame 41, connects the first sliding block 42 and the first clamping groove 34, and causes the U-shaped sliding frame 41 to ascend and descend through the contraction and extension of the electric push rod 33, so that the limiting ring 92, the two vertical rods 94 and the filter cylinder 10 ascend and descend, and the connecting ring 93, the two vertical rods 94 and the filter cylinder 10 rotate at the same time through the sliding of the positioning block 95 in the spiral groove 96. The blades 202 form a spiral three-dimensional motion track, which covers the full height range of the filter cylinder 10 and expands the crushing area. The synchronous action of the rotary cutting and the lifting and pulling facilitates the efficient crushing of the internal water grass without dead angle and ensures the complete removal of the water grass, thereby avoiding affecting the monitoring of the radar water level meter 7. The oblique arrangement of the blades 202 can better cut off the water grass, conveniently stir the river water, drive the surrounding water body to form directional flow and vortex, conveniently stir the crushed water grass out of the monitoring range, and facilitate the subsequent placement of the filter cylinder 10 in the river water.
