[0028] See also Figure 1-6 , the utility model provides an embodiment: a water distribution device from a main channel to a branch channel, comprising a frame 1 for installation and fixing;

[0029] A rotating disk 2 is rotatably mounted on the upper end of the frame 1;

[0030] The screw rod 3 is rotatably mounted in the frame 1, and the upper end of the screw rod 3 is inserted into the rotating disk 2 through a thread;

[0031] The gate 4 is movably installed in the frame 1, and the upper end of the gate 4 is connected to the lower end of the screw rod 3;

[0032] Grooves 5 are provided at the left and right ends and the lower end of the frame 1;

[0033] The anti-sediment component is movably installed in the lower end of the frame 1. The anti-sediment component is used to prevent the sediment in the water flow from accumulating in the lower end of the frame 1 when the gate 4 is opened. The device drives the anti-sediment component to move upward when the gate 4 is opened, and closes the lower end opening of the frame 1 through the anti-sediment component to prevent the sediment in the water flow from accumulating in the lower end opening of the frame 1;

[0034] Furthermore, the anti-silt assembly includes two groups of first sliders 6 and two groups of movable grooves 7. The two groups of first sliders 6 are fixedly installed on the left and right ends of the gate 4. The two groups of first sliders 6 are movably inserted in the two groups of grooves 5. The two groups of movable grooves 7 are opened in the two groups of first sliders 6. Pull ropes 8 are movably installed in the two groups of movable grooves 7. The two groups of pull ropes 8 are sleeved with springs 9. The lower ends of the two groups of springs 9 are against the inner walls of the lower ends of the two groups of movable grooves 7. The lower end of the frame 1 is symmetrically opened with slide grooves 10. The lower ends of the grooves 5 are symmetrically opened. A baffle 11 is movably installed inside, and a second slider 12 is fixedly installed at the lower end of the two groups of movable grooves 7. The two groups of second sliders 12 are fixedly installed on the left and right ends of the baffle 11. When the gate 4 moves upward, the baffle 11 and the second slider 12 are driven upward by two groups of pull ropes 8. The baffle 11 closes the opening of the groove 5 at the lower end of the frame 1, and the sliding length of the pull rope 8 is adapted through the spring 9 in the movable groove 7, and the pull rope 8 can be straightened to prevent mud and sand from entering the groove 5 under the frame 1.

[0035] Furthermore, the upper ends of the two groups of slide grooves 10 are not connected to the lower sides of the grooves 5 at the left and right ends of the frame 1, and the inner wall of the upper side of the slide groove 10 is lower than the opening of the groove 5 at the lower end of the frame 1. This structure prevents the baffle 11 and the second slider 12 from sliding out of the groove 5 at the lower end of the frame 1 when the baffle 11 and the second slider 12 move upward according to the distance between the slide groove 10 and the groove 5.

[0036] Furthermore, a storage groove 13 is opened in the gate 4, a cross bar 14 is fixedly installed between the upper ends of the two groups of pull ropes 8, and a blocking net 15 is fixedly installed between the cross bar 14 and the upper side of the baffle 11. The blocking net 15 is in the storage groove 13. When the gate 4 moves upward, the gate 4 slides out of the storage groove 13, and the large debris in the water flow is filtered through the blocking net 15 to prevent the large debris from flowing out from the opening of the gate 4.

[0037] Furthermore, a rubber pad 16 is provided on the upper side of the baffle 11 , and the width of the rubber pad 16 is consistent with the width of the baffle 11 . The rubber pad 16 moves the baffle 11 upward to seal the opening of the groove 5 at the lower end of the frame 1 .

[0038] Furthermore, the thickness of the rubber pad 16 is consistent with the distance between the groove 5 and the slide groove 10. According to the rear end of the rubber pad 16, when the baffle 11 moves upward and blocks the opening of the groove 5 at the lower end of the frame 1, the space between the upper side of the baffle 11 and the opening of the groove 5 at the lower end of the frame 1 is filled by the rubber pad 16.

[0039] Furthermore, two groups of brush plates 17 are fixedly installed at the lower end of the gate 4, and scrapers 18 are fixedly installed at the lower ends of the two groups of brush plates 17. The two groups of brush plates 17 and the two groups of scrapers 18 are in contact with the front and rear sides of the blocking net 15. When the gate 4 moves down and the gate 4 is taken in, the two groups of brush plates 17 and the two groups of scrapers 18 are used to scrape and clean the impurities remaining on the surface of the gate 4, so as to avoid the accumulation of certain impurities on the gate 4 and the inability to take it in.

[0040] Working principle: When the gate 4 is opened from the frame 1, Figure 2 and Figure 3 As shown, by rotating the rotating disk 2, the screw rod 3 moves upward, and the screw rod 3 moves upward to drive the gate 4 to slide upward in the grooves 5 at the left and right ends of the frame 1. When the gate 4 moves upward, the pull ropes 8 in the two sets of movable grooves 7 move upward, and the two sets of pull ropes 8 move upward to drive the second slider 12 and the baffle 11 to move upward in the groove 5 and the slide groove 10 at the lower end of the frame 1. After the second slider 12 moves to the upper end of the slide groove 10, the second slider 12 is pulled to drive the pull rope 8 to slide in the movable groove 7. The pull rope 8 slides in the movable groove 7 and squeezes the spring 9. Under the action of the restorative elastic force of the spring 9, the pull rope 8 is straightened. When the baffle 11 moves to the opening of the groove 5 at the lower end of the frame 1, the opening of the groove 5 under the frame 1 is sealed, and when the gate 4 moves upward to open, as shown in FIG. Figure 4 As shown, the baffle 11 does not move, and the blocking net 15 slides out from the storage groove 13, so as to block the opening of the gate 4 and prevent large debris from flowing out through the opening of the gate 4. The above is the entire working principle of the utility model.
