Specific implementation
[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0031] Reference Figures 1-3 The utility model provides an embodiment: a water conservancy project channel shunt structure, including main channel 1 and branch channel 2, main channel 1 is the main channel in water conservancy irrigation channel, is used to transport large flow water source, and branch channel 2 is the secondary channel in irrigation channel, and the shunt conveying of water flow is solved. The connecting place of main channel 1 and branch channel 2 is fixedly connected with crossbeam 4, and crossbeam 4 bottom is installed with gate 6 through drive assembly, and gate 6 blocks the connecting place of main channel 1 and branch channel 2, and the shunt is realized through the opening and closing of gate 6. The diameter of gate 6 is equal to the inner diameter of branch channel 2, and is less than the inner diameter of main channel 1, and the purpose of such design is to completely block the connecting place of main channel 1 and branch channel 2 when gate 6 is closed, at this time, water flow does not enter the inside of branch channel 2, and when gate 6 is completely opened, the channel is not blocked. Drive assembly includes motor 5, and motor 5 is fixedly connected at the top of crossbeam 4, and the bottom output end of motor 5 is fixedly connected with gate 6 after penetrating crossbeam 4, and the rotation of gate 6 is driven by driving motor 5 to work to realize the opening and closing of the shunt. The power supply of motor 5 comes from external power supply, and it is the infrastructure in the existing arrangement, belongs to prior art, and will not be described in detail here.
[0032] Reference Figures 3-4The filter assembly is detachably installed on the left and right sides of the gate 6 and is used to collect impurities in the channel; the filter assembly comprises filter screens 9, which are installed on the outer side of the gate 6. When the gate 6 is closed, one set of filter screens 9 filters the water flow inside the main channel 1, and the other set is in a resting state. A plurality of groups of mesh holes one 11, mesh holes two 12 and mesh holes three 13 are sequentially formed in the outer side of the filter screen 9 from bottom to top. The mesh holes one 11 are small-sized openings and are used to collect small impurities. After the impurities enter the mesh holes two 12 and mesh holes three 13, the collected large impurities are prevented from leaking out from the bottom through the mesh holes one 11. The mesh holes two 12 are larger than the mesh holes one 11 and are used to collect large particles in the water flow. The mesh holes three 13 are the largest in size and are used to collect floating objects in the water flow, such as fallen leaves and dry branches. A plurality of groups of connecting bolts two 10 are fixedly connected to the outer side of the gate 6, and the filter screens 9 are connected to the gate 6 through the connecting bolts two 10. When the filter screens 9 are used for a long time or need to be fully cleaned, the filter screens 9 can be detached through the connecting bolts two 10.
[0033] With reference to Figures 2-4 The filter screen 9 is internally provided with a collection assembly. The collection assembly comprises a mesh bag 14, which is slidingly connected inside the filter screen 9. The impurities entering from the mesh holes one 11, mesh holes two 12 and mesh holes three 13 finally fall into the mesh bag 14 for collection, so as to reduce the scattering of impurities. A handle 15 is fixedly connected to the middle of the mesh bag 14. When cleaning is needed, the mesh bag 14 can be taken out through the handle 15, so as to facilitate the cleaning of the impurities inside. The gate 6 is rotatably connected to a rotating disc 3. The filter screen 9 is overlapped on the upper part of the rotating disc 3, and the rotating disc 3 is fixed at the connection between the main channel 1 and the branch channel 2. The rotating disc 3 assists the rotation of the filter screen 9, so as to avoid the rotation blockage caused by the direct contact between the filter screen 9 and the bottom of the main channel 1 and the branch channel 2. A plurality of groups of rotating plates 18 are rotatably connected to the inner wall of the filter screen 9. The rotating plates 18 block the inner sides of the mesh holes two 12 and mesh holes three 13. After the filter screen 9 rotates, the rotating plates 18 on the side facing the water flow are opened under the impact of the water flow, so as to facilitate the entry of impurities into the filter screen. The rotating plates 18 on the side opposite to the water flow are attached to the inner wall of the filter screen 9 under the impact of the water flow, so as to avoid the discharge of the entered impurities from the other side of the mesh holes. This ensures the effective collection of impurities. After the filter screen 9 completes the rotation, the working state of the rotating plates 18 also changes. The originally closed rotating plates 18 are opened under the impact of the water flow, so as to realize the bilateral collection of impurities
[0034] With reference to Figures 2-4The end of the gate plate 6 is provided with a connecting bolt 8, and the outer side of the connecting bolt 8 is provided with a sealing gasket 7. The sealing gasket 7 is used to abut the gate plate 6 and the edge of the branch opening, thereby providing the sealing property of the gate plate 6. The connecting bolt 8 is convenient for mounting and dismounting the sealing gasket 7. The outer side of the gate plate 6 is rotatably connected with a cover plate 16. The cover plate 16 is connected with the outer side of the filter screen 9 through a lock buckle 17. In the default state, the cover plate 16 covers the upper part of the filter screen 9, and blocks the opening of the upper part of the filter screen 9.
[0035] Working principle: The water source is transported through the main channel 1. In the process of water flow, part of the water flow enters the inside of the filter screen 9 through the mesh hole 11, the mesh hole 12 and the mesh hole 13. Under the action of the water flow, the side rotating plate 18 is opened, and the impurities enter the mesh hole 12 and the mesh hole 13 along the water flow. The filter screen 9 is used to collect the impurities such as silt and fallen leaves carried in the water flow in the main channel 1, thereby reducing the amount of impurities in the water flow in the main channel 1, improving the transportation efficiency of the water flow, and reducing the blockage of the main channel 1.
[0036] When the branch operation is needed, the gate plate 6 is driven to rotate by the driving motor 5. At this time, the branch opening between the branch channel 2 and the main channel 1 is opened, and the water source in the main channel 1 enters the inside of the branch channel 2. At the same time, when the water flow enters, the impurities at the branch opening position are still collected through the filter screen 9, so as to avoid the impurities entering the inside of the branch channel 2. The branch size is controlled by the rotation angle of the gate plate 6.
[0037] When the impurities stored in the filter screen 9 reach a certain amount, the lock buckle 17 is opened and the cover plate 16 is lifted. At this time, the net bag 14 in the filter screen 9 can be lifted through the handle 15. At this time, the impurities stored in the filter screen 9 are moved upward synchronously, and finally the impurities are cleaned. After cleaning, the net bag 14 is put back, and the filter screen 9 can be used again. The operation is simple.
[0038] When the impurities in the filter screen 9 in the main channel 1 area need to be cleaned, the gate plate 6 is rotated by 180° through the driving motor 5. At this time, the filter screen 9 in the main channel 1 is rotated into the branch channel 2. At this time, the impurities can be cleaned, and the gate valve does not need to be closed during the cleaning process, so as to ensure the continuity of the water channel work. The filter screen 9 in the branch channel 2 can be dismounted by removing the connecting bolt 10 in one way. This makes the filter screen 9 also not need to be closed during replacement, and further ensures the continuity of the water channel work.
[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
