Technical Field
[0001] The utility model relates to the technical field of river flood discharge, in particular to a gate structure for river flood discharge. Background Art
[0002] With the popularity of water conservancy projects, gates are not only used in large water conservancy projects in larger rivers, dams and ditches, but also in some small water conservancy projects, such as ponds for irrigation or breeding. Large water conservancy projects generally use large hydraulic systems and other pressure equipment to control the rise or fall of the gates to achieve the function of flood discharge, but the cost is high. If small water conservancy projects are also controlled by hydraulic systems, the high cost is difficult for people to accept, and even the gates in small water conservancy projects are almost impossible to control the rise or fall of the flood discharge gates by manpower.
[0003] When the existing gate structure is used, after the gate is raised to discharge flood water, silt and excess materials are usually accumulated on the gate. When the gate is lowered again, the silt and excess materials will cause the gate to get stuck and prevent the gate from falling normally. Therefore, it is necessary to redesign a gate structure for river flood discharge to address the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-3A gate structure for flood discharge in a river comprises a mounting frame 1, a mounting frame 2 is fixedly connected to the mounting frame 1, a motor 3 is arranged on the upper end surface of the mounting frame 2, an output shaft of the motor 3 passes through the mounting frame 2 and is extended to be installed with a threaded rod 7, a slide groove 6 is opened on the mounting frame 1, a first gate 4 and a second gate 5 are slidably arranged in the slide groove 6, and the first gate 4 is connected to the threaded rod 7, a guide rod 9 is connected to the second gate 5, a reset device is fixedly installed on the bottom wall of the slide groove 6, and the output end of the reset device abuts against the bottom end of the second gate 5.
[0021] First sliders 8 are fixedly mounted on both sides of the first gate 4 , and one of the first sliders 8 is threadedly connected to the threaded rod 7 , and one end of the guide rod 9 passes through the first slider 8 at the corresponding position.
[0022] A second slider 11 is fixedly installed on one side of the second gate 5, and the guide rod 9 is fixedly connected to the second slider 11. It should be noted that the movement of the guide rod 9 can drive the second slider 11 to move synchronously. A limit block 10 is fixedly installed on one end of the guide rod 9. It should be noted that the limit block 10 can be driven to move by the first slider 8.
[0023] The reset device includes two load-bearing plates 14 and a mounting plate 12, and the two load-bearing plates 14 are fixedly mounted on the bottom wall of the slide groove 6, and the mounting plate 12 is slidably clamped in the slide groove 6, and a top block 16 is symmetrically fixedly mounted on the bottom end of the mounting plate 12, and a spring 15 is sleeved on the outer wall of each top block 16, and the two springs 15 are respectively in contact with the bottom end of the load-bearing plate 14 corresponding to the position.
[0024] A crushing block 13 is fixedly mounted on the top of the mounting plate 12, and the crushing block 13 contacts the bottom end of the second gate 5. It should be noted that when the bottom end of the second gate 5 contacts the crushing block 13, the excess material between the second gate 5 and the crushing block 13 will be cut off.
[0025] When the utility model is in use, the motor 3 can be started first, and the output shaft of the motor 3 drives the threaded rod 7 to rotate, and then the threaded rod 7 will drive the first slider 8 threadedly connected thereto to slide in the slide groove 6, and the first slider 8 will drive the first gate 4 to slide synchronously, and flood discharge can be carried out at this time.
