[0021] Example 1

[0022] A water gate segmented water taking device of hydraulic engineering, as shown in Figures 1-3 Fig. 1, comprising a dam 1, a gate 2 connected to the front side of the middle of the dam 1, a mounting frame 3 connected to the rear side of the gate 2, a toothed plate 4 rotatably connected to the mounting frame 3, a water outlet 41 opened in the left part of the toothed plate 4, a mounting port 42 opened in the lower left part of the toothed plate 4, a drive assembly 5 mounted on the upper rear side of the mounting frame 3, the drive assembly 5 comprising a mounting seat, a drive motor and a gear, the mounting seat connected to the upper rear side of the mounting frame 3, the drive motor mounted on the mounting seat, the gear connected to the output shaft of the drive motor, the gear engaged with the toothed plate 4, and a water outlet plate 6 also connected to the output shaft of the drive motor, the water outlet plate 6 being detachably connected, three filter screens 7 connected to the water outlet plate 6, and three filter screens 7 also connected to the gate 2, and a cleaning mechanism 8 provided on the rotating tooth.

[0023] As shown in Figure 2 and Figure 4As shown, the cleaning structure includes a mounting plate 82, the mounting plate 82 is connected on the mounting opening 42, the nylon brush 81 is rotatably connected on the mounting plate 82, the first sliding groove 83 symmetrical up and down is opened on the left rear side of the gate plate 2, the second sliding groove 84 is opened on the right rear side of the gate plate 2, and the nylon brush 81 can slide in the first sliding groove 83 and the second sliding groove 84.

[0024] It should be noted that the water conservancy project realizes effective management and optimal allocation of water resources by building various hydraulic structures to meet the needs of human society in flood control, irrigation, water supply, power generation, navigation, environmental protection and the like. The water gate segmented water taking is a common water resource management technology. A plurality of water taking openings are arranged at different positions of the water gate to realize fine control and distribution of water flow and meet the needs of different users. When water taking is needed, the driving motor is started, the output shaft of the driving motor rotates to drive the gear to rotate, and then drives the toothed plate 4 to rotate, so that the water outlet 41 is adjusted to the appropriate position according to the water level state in the water channel, so that the water outlet 41 corresponds to the filter screens 7 on the front and rear sides. After the water flow is filtered by the filter screen 7 on the front side, it will pass through the water outlet 41 and flow out from the filter screen 7 on the rear side, thereby realizing water gate segmented water taking. The filter screen 7 filters the inflowing water flow and removes large particles. After a long time of operation, a large number of large particles will accumulate on the outside of the filter screen 7 on the front side. These particles will affect the filtering effect of the filter screen 7 and will hinder the water flow speed, affecting the water taking efficiency. The impurities on the filter screen 7 need to be cleaned in time. The utility model sets the cleaning mechanism 8. When the driving assembly 5 drives the toothed plate 4 to rotate, the nylon brush 81 will also rotate. The nylon brush 81 cleans the adjacent filter screen 7. This linkage mode can save cleaning cost and improve cleaning effect. When the nylon brush 81 is cleaning, it will be in a squeezed state. To prevent the nylon brush 81 from deforming and being damaged due to being in a squeezed state for a long time, the utility model sets the first sliding groove 83 and the second sliding groove 84. When the nylon brush 81 is in a non-cleaning state, it slides on the first sliding groove 83 and the second sliding groove 84, thereby releasing the nylon brush 81 and restoring it to the initial state, which is beneficial to prolong the service life and cleaning effect of the nylon brush 81.

[0027] It should be noted that, since the water channel is often accompanied by mud and sand, when the water flows through the filter screen 7, the mud and sand will move, when the mud and sand contact the water outlet plate 6 or the gate plate 2, the mud and sand will flow out through the lower outlet 92, under the action of the second baffle 93, the mud and sand will flow into the bottom of the water channel again, and the second baffle 93 can prevent the mud and sand from flowing upward and entering the filter screen 7 again, so as to block the mud and sand.

[0028] Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
