Description

Technical Field

[0001] The utility model relates to the field of water conservancy gates, in particular to a diversion gate for a water conservancy project. Background Art

[0002] At present, water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. In the field of agricultural irrigation, the construction of water conservancy projects can optimize the environment for agricultural development and provide a stable and reliable water source for crop growth. In the process of farmland irrigation, water conservancy projects can fully meet irrigation needs and realize the effective storage and full utilization of water resources.

[0003] In the allocation of water resources for agricultural irrigation, canals are usually used to guide water flow, and gates are used at the front and rear ends of the diversion outlet to block and control the water flow. Since both the canals and water source rivers are open-air areas, it is inevitable that some domestic garbage will fall into the water. Trash booms are usually used in large rivers to block garbage pollutants, but in irrigation systems, waterway space is usually limited. Setting up a separate trash boom requires additional space, which affects the smoothness of the water flow. In addition, the irrigation system needs to be adjusted frequently, usually according to the needs of crop growth, seasonal changes, water resource conditions and other factors. If a trash boom is installed separately, it is sometimes necessary to frequently move or adjust the trash boom to adapt to the water flow, which causes inconvenience to use. Utility Model Content

[0018] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Examples, such as Figure 1-Figure 4 As shown: The utility model provides a diversion gate for a water conservancy project, whose structure includes a door frame 1 and a gate plate 2 slidably installed in the door frame 1, the door frame 1 is arranged in a water channel of an irrigation system, a pull rod 3 is provided at the top of the gate plate 2, and a traction machine 4 is provided at the top of the door frame 1 and connected with the pull rod 3 for lifting and lowering the gate plate 2. It is known to those skilled in the art that the pull rod 3 is a worm, and the traction machine 4 is an electric worm gear box, which drives the worm to rise or fall, thereby driving the gate plate 2 to open or close.

[0020] Among them, a sewage drain 5 is provided on one side of the gate plate 2 close to the upstream of the water flow. The sewage drain 5 is located below the water level in front of the closed gate plate 2. Usually, garbage pollutants will float on the water surface and then accumulate in front of the gate plate 2. When the water source is poor, that is, when there are more deposited garbage pollutants, the sewage drain 5 can also be set at the bottom of the gate plate 2. When the gate plate 2 is lifted, the pollutants at the bottom of the canal can be brought up together. The same sewage drain 5 can also be provided with multiple sewage drains at different horizontal heights, such as one near the water surface and one at the bottom of the water. Those skilled in the art can set it according to actual needs, which will not be repeated here;

[0021] Moreover, in this embodiment, a cleaning assembly 6 is provided on the door frame 1, and the cleaning assembly 6 includes a cleaning bucket 61 that moves at the front end of the door frame 1, and the cleaning bucket 61 moves to the path where the scoop 5 moves downward to clean the scoop 5, that is, when the scoop 5 follows the gate plate 2 to rise and release water, it will also drive garbage and pollutants to accumulate on the scoop 5. When it is necessary to close the gate and shut off the water, the gate plate 2 descends, and the scoop 5 follows the gate plate 2 to descend and passes through the cleaning bucket 61, so that the pollutants remain in the cleaning bucket 61;

[0022] Specifically, the scoop 5 is arranged in a plurality of strip-shaped structures at intervals in the transverse direction, the cleaning bucket 61 is bucket-shaped and has bucket teeth 61a arranged at intervals near the front end of the scoop 5, and the bucket teeth 61a of the scoop 5 and the cleaning bucket 61 are staggered so that the descending scoop 5 moves in the gaps between the bucket teeth 61a.

[0023] At the same time, the cleaning and drainage component 6 also includes a swing frame 62, the top of the swing frame 62 is hingedly connected to the door frame 1, and the cleaning and drainage bucket 61 is swingably connected to the door frame 1 through the swing frame 62. A pushing member 63 is provided on the door frame 1 and is connected to the swing frame 62. It is used to control the swing frame 62 to swing. The pushing member 63 known to those skilled in the art can be a cylinder, an electric cylinder, etc., and it is only necessary to achieve the push-pull function to make the swing frame 62 swing. In this embodiment, an electric cylinder is used, that is, a modular product with an integrated design of a servo motor and a lead screw. The rotational motion of the servo motor is converted into a linear motion through a lead screw for pushing and pulling. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0024] It can be seen that the bucket teeth 61a of the cleaning bucket 61 carry the materials exchanged from the sewage drain 5. It should be noted that when the cleaning bucket 61 swings to a position where it does not interfere with the rising sewage drain 5, the horizontal height of the outer end of the bucket teeth 61a is higher than the inner side of the bucket teeth 61a, that is, when the sewage drain 5 has not been cleaned yet, the cleaning bucket 61 swings outward to a position where it does not interfere with the sewage drain 5. At this time, the cleaning bucket 61 still carries the pollutants in a bucket shape, that is, the inside is low and the outside is high, which prevents the pollutants from falling into the canal.

[0025] In the specific implementation, some garbage pollutants are accumulated in the water flow in front of the gate plate 2 which is mainly used for intercepting water inlet in front of the canal. At this time, the electric cylinder pusher 63 drives the swing frame 62 to swing outward, so that the cleaning bucket 61 is away from the gate plate 2. Then the electric worm gear box traction machine 4 drives the worm pull rod 3 to rise, thereby driving the gate plate 2 to open upward. The sewage scoop 5 follows the gate plate 2 to rise and release water, and at the same time, the garbage pollutants will be scooped up and collected on the sewage scoop 5. After the canal is released, the diversion operation is performed to drain and irrigate the farmland, thereby avoiding excessive Pollutants flow into the farmland. When the gate is closed and water is released, the cylinder pusher 63 drives the swing frame 62 to swing inward, so that the cleaning bucket 61 moves to the path where the sewage drain 5 moves downward. The gate plate 2 moves downward, and the sewage drain 5 follows the gate plate 2 to descend. When the sewage drain 5 passes through the cleaning bucket 61, the teeth 61a of the sewage drain 5 and the cleaning bucket 61 are staggered, so that the descending sewage drain 5 moves in the gap between the teeth 61a, so that the pollutants remain in the cleaning bucket 61, thereby cleaning the pollutants on the sewage drain 5 and preventing them from returning to the canal.

[0026] Moreover, a base plate 64 is provided on the swing frame 62, a slide rail 61b is horizontally provided on the cleaning bucket 61, and a slide groove matching the slide rail 61b is provided on the base plate 64. The cleaning bucket 61 is connected to the swing frame through the slide rail 61b matching the slide groove of the base plate 64, and a handle is provided on the side end of the cleaning bucket 61, which is convenient for the user to pull the cleaning bucket 61 out of the base plate 64 for cleaning pollutants.

[0027] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
