Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] refer to Figure 1-Figure 7 The device for monitoring seepage and pressure shown in the figure includes a measuring box 1, a monitoring device 2, and a dam body 3. The measuring box 1 and the monitoring device 2 are both arranged on the dam body 3. It should be noted that, in this embodiment, the installation method of the measuring box 1 and the monitoring device 2 can refer to the technical content adopted in the prior art Chinese patent publication number CN114894234A, which discloses a dam seepage pressure and seepage flow monitoring device for water conservancy projects. The details are not repeated here. The measuring box 1 is provided with a filtering mechanism for filtering sand and gravel, and the measuring box 1 is provided with a cleaning mechanism for cleaning the filtering mechanism.

[0029] The filtering mechanism includes a coarse filter plate 5 and a fine filter plate 10. The coarse filter plate 5 is rotatably installed in the measuring box 1 through a flip assembly. A wave-breaking plate 4 is fixedly installed on the top inner wall of the measuring box 1. The outer wall of the fine filter plate 10 is fixedly connected to the side of the wave-breaking plate 4 and the inner wall of the measuring box 1.

[0030] The cleaning mechanism includes two rectangular columns 12. Two lifting grooves are provided on the side of the wave-breaking plate 4. The two rectangular columns 12 are slidably installed in the two lifting grooves through lifting components. The sides of the two rectangular columns 12 are jointly fixed with a sealing plate 18. The coarse filter plate 5 is provided with a control component for driving it to flip. A side box 19 is fixedly provided on the side of the measuring box 1, and a cleaning component compatible with the fine filter plate 10 is provided in the side box 19.

[0031] With the above structure, when in use, when it is necessary to clean the coarse filter plate 5 and the fine filter plate 10, first, the two rectangular columns 12 are driven to move upward synchronously through the lifting component. When the two rectangular columns 12 move upward, the sealing plate 18 is driven to move upward synchronously to seal the filter holes of the fine filter plate 10. When the rectangular columns 12 move upward, the coarse filter plate 5 is driven to flip through the control component, so that the large particles of sand and gravel on the top fall to the top of the fine filter plate 10, and are cleaned by the cleaning component. The cleaning operation is simple and practical.

[0032] Example 2

[0033] like Figure 3 、 Figure 4 As shown, the flip assembly includes two mounting shafts 6. Two mounting holes are defined on the sides of the coarse filter plate 5.

The opposite inner walls of the measuring box 1 are each defined by an arcuate groove. Arc-shaped sliders 7 are slidably mounted in the two arcuate grooves via elastic units. The two ends of the other mounting shaft 6 are rotatably connected to the opposite sides of the two arcuate sliders 7. By rotatably mounting the two ends of the mounting shaft 6 on the opposite inner walls of the measuring box 1, the mounting shaft 6 can drive the coarse filter plate 5 to flip synchronously by a certain angle when rotating. The elastic unit includes an arcuate spring 9. The arcuate slider 7 has an arcuate guide hole defined in it. An arcuate guide rod 8 is slidably mounted in the arcuate guide hole.

[0034] Specifically, in the normal state, the elastic action of the arc spring 9 can support the coarse filter plate 5, keep it in a horizontal state, and play a filtering function. When one of the mounting shafts 6 rotates, the arc slider 7 slides in the arc groove, thereby driving the coarse filter plate 5 to flip synchronously to prevent it from getting stuck.

[0037] Specifically, the lifting motor 15 is started, and the two screws 13 are driven to rotate synchronously through the meshing action of the two sprockets 14 and the chain, thereby driving the two rectangular columns 12 to rise and fall synchronously under the action of the threads, thereby driving the sealing plate 18 to realize the lifting function and enabling the coarse filter plate 5 to realize the flipping function.

[0038] Example 4

[0039] like Figure 6 As shown, the control component includes a gear 16. A square hole is provided on the top of the coarse filter plate 5.

Through the meshing action of the gear 16 and the rack 17, the rack 17 can drive the mounting shaft 6 to rotate during the lifting process through the meshing action with the gear 16. The two gears 16 are respectively located in the two square holes, and the sides of the two rectangular columns 12 are fixedly mounted with racks 17, and the two racks 17 are respectively adapted to the two gears 16.

[0040] Specifically, when the rectangular column 12 moves upward, it can drive the two racks 17 to move upward synchronously. Through the meshing action of the rack 17 and the gear 16, it can drive the gear 16, the mounting shaft 6, and the coarse filter plate 5 to achieve a synchronous flipping function.

[0041] like Figure 7 As shown, the cleaning component includes an electric telescopic rod 20, and a cleaning hole is provided in the side box 19 and the measuring box 1.

A collecting hole is provided on the side of the side box 19, and a collecting box 22 is slidably installed in the collecting hole.

[0042] Specifically, when the top of the fine filter plate 10 needs to be cleaned, the cleaning scraper 21 is driven by the electric telescopic rod 20 to move horizontally, and the sand and gravel on the top of the fine filter plate 10 are scraped into the collection box 22 for collection.
