Abstract
Description
Technical Field
[0001] This application belongs to the field of farmland drainage, and specifically relates to an ecological drainage sluice. Background Art
[0002] In some places where farmland drainage facilities are relatively complete, there are relatively systematic drainage canal systems, pumping stations and other facilities, which can better cope with the discharge of excess water after a certain amount of rainfall and irrigation. However, in some places where drainage facilities are insufficiently constructed, many farmlands lack effective drainage channels, or the drainage canal systems are imperfect, resulting in poor drainage.
[0003] [[ID=​11]]At present, the main methods of farmland drainage include open ditch drainage, buried ditch drainage, horizontal drainage, well point drainage, etc. In practical applications, usually according to different topographies, soil conditions and crop planting situations, etc., a variety of drainage methods are combined to achieve better drainage effects. For example, in the relatively flat plain areas, open ditch drainage and buried ditch drainage may be combined; in low-lying and waterlogging-prone areas, well point drainage and other methods may be added.
[0004] With the change of climate, the number of extreme weather events has increased, and the frequency of heavy rainfall and other situations has increased, which puts higher requirements on the drainage capacity of the farmland drainage system. At the same time, in the process of agricultural modernization, the application of some new planting models and agricultural technologies has also put forward new demands for farmland drainage, such as the precise drainage requirements in facility agriculture. The farmland drainage often contains a large amount of pollutants such as pesticides, fertilizers or impurities. If this drainage is directly discharged into the water body, it will pollute the surrounding rivers, lakes and other water bodies and affect the water ecological environment. Especially in some areas with relatively serious agricultural non-point source pollution, the farmland return water has become one of the important sources of water body pollution. At the same time, when the farmland return water occurs, it may take away the fertile soil in the farmland, which not only causes soil erosion, but also is not conducive to the retention of fertilizers in the farmland. The existing drainage sluices usually consist of a cast-in-place outer frame and a gate plate, or are connected to the side wall of the drainage ditch with cement, and the construction quality often cannot be guaranteed, and the leakage phenomenon at the gate connection is serious, which does not meet the requirements of water conservation in high-standard farmland. Summary of the Invention
[0005] The purpose of this application is to overcome the defects of the existing drainage sluice, such as complex construction, inability to block sediment, and easy leakage at the outlet.
[0006] In order to achieve the above purpose, this application proposes an ecological drainage sluice, including:
[0007] The outer frame of the sluice gate; the outer frame of the sluice gate includes a square bottom plate and a square back plate perpendicular to the bottom plate; on both sides of the bottom plate and the back plate are two side plates perpendicular to both the bottom plate and the back plate; ditto
[0008] The water outlet pipe is located at the position of the back plate close to the bottom plate, penetrates through the back plate, and is fixedly connected to the back plate in a sealed manner;

[0011] The mudguard stands upright in the middle of the bottom plate or at one end of the bottom plate away from the back plate, and is detachably connected to the two side plates.
[0012] As an improvement of the above ecological drainage gate, the bottom plate, the back plate and the two side plates are integrally formed.
[0013] As an improvement of the above ecological drainage gate, the outer frame of the gate is a concrete structure or a reinforced concrete structure.
[0014] As an improvement of the above ecological drainage gate, the gate structure includes:
[0015] The plug gate frame with a mouth-shaped structure; the plug gate frame is a two-layer structure with a gap in the middle;
[0016] The gate plate is inserted downward from the gap of the plug gate frame;
[0017] The back plate is reserved with flange nuts; bolts are used to fixedly connect the plug gate frame to the flange nuts of the back plate.
[0018] As an improvement of the above ecological drainage gate, the gate structure further includes an opening positioning device;
[0019] The opening positioning device is multiple groups of marbles distributed on both sides of the gap of the plug gate frame and a group of grooves at the relative positions on both sides of the gate plate.
[0020] As an improvement of the above ecological drainage gate, the relative positions in the middle of the two side plates protrude outward to form protruding parts; the mudguard is located at the edge of the protruding part close to the filter screen side or at the middle position of the protruding part.
[0021] As an improvement of the above ecological drainage gate, there are multiple mudguards.
[0022] As an improvement of the above ecological drainage gate, the heights of the multiple mudguards are the same or gradually increase along the water flow direction.
[0023] As an improvement of the above ecological drainage gate, the water outlet pipe has a downward inclination.

[0027] 2. The mudguard is used to intercept sediment, reducing soil erosion in farmland;

[0047] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.
[0048] As Figures 1-5 shown, it is the first embodiment of the ecological drainage sluice of the present application.
[0049] The ecological drainage sluice may include a gate outer frame 1. The gate outer frame 1 may include a square bottom plate 11 and a square back plate 12 perpendicular to the bottom plate 11. On two sides of the bottom plate 11 and the back plate 12, there may be two side plates 13 perpendicular to both the bottom plate 11 and the back plate 12. The bottom plate 11, the back plate 12 and the two side plates 13 may be integrally formed to ensure that the gate outer frame 1 does not leak. The side edges of the side plates 13 that do not contact the bottom plate 11 and the back plate 12 may be arc-shaped. The gate outer frame 1 is a concrete structure or a reinforced concrete structure.
[0050] At the part of the back plate 12 close to the bottom plate 11, there may be a water outlet pipe 7 that slopes downward and penetrates through the back plate 12. The water outlet pipe 7 may be integrally formed with the gate outer frame 1, or a through hole may be reserved on the back plate 12 first, and then the water outlet pipe 7 passes through the hole and is sealed and fixed. The water outlet pipe 7 is a PE pipe or a drainage pipe made of other materials. The existing ecological drainage sluices do not provide a downward-sloping water outlet pipe 7, but only reserve a through hole in the back plate 12, and for the convenience of production, the axis of the hole is perpendicular to the back plate 12. When in use, the drainage pipe needs to have a certain downward slope angle, and at this time, the drainage pipe and the hole on the back plate 12 are often not well sealed, resulting in leakage. In the production of the present application, the water outlet pipe 7 with a certain inclination angle is fixed on the back plate 12 or integrally formed with the back plate 12. When in use, one end of the drainage pipe is sleeved with the water outlet pipe 7, which can avoid the defect of difficult sealing during later installation.
[0051] On the inner side of the backplate 12, a mouth-shaped plug gate frame 2 can be fixedly connected. Flange nuts 9 can be embedded around the inner side of the backplate 12, and bolts 10 can be used to fix the plug gate frame 2 on the backplate 12, so that the plug gate frame 2 is closely attached to the backplate 12 to prevent water leakage. The plug gate frame 2 can be a two-layer structure, and there can be a gap between the two layers. A gate plate 3 can be inserted into the gap. The upper part of the gate plate 3 can have a handle for convenient manual grasping of the gate plate 3. On both sides of the gap of the plug gate frame 2, multiple groups of marbles can be symmetrically arranged, and a set of grooves can be arranged at the relative position on the side of the gate plate 3. When the groove of the gate plate 3 is at the height of a set of marbles, this set of marbles can prevent the gate plate 3 from falling. The multiple groups of marbles enable the gate plate 3 to stay at multiple different heights in the gap of the plug gate frame 2, thus controlling the exposed area of the water outlet pipe 7 and the drainage speed. When the gate plate 3 is pressed downward forcefully, the marbles can retract, allowing the gate plate 3 to descend. When the gate plate 3 is completely lowered, the water outlet pipe 7 can be completely blocked to prevent water from flowing out of the water outlet pipe 7. The plug gate frame 2 is made of PVC, PE materials, or other hard materials. In other embodiments, an electric method such as a motor can also be used to control the rising and falling of the gate plate 3. The position of the gate plate 3 can also be controlled by a gear method: two gears are arranged on both sides of the gap of the plug gate frame 2, and racks are arranged on both sides of the gate plate 3 to mesh with the gears. By rotating the gears, the rising and falling of the gate plate 3 can be controlled. At the same time, the position of the gate plate 3 can be fixed by fixing the rotation of the gears. The plug gate frame 2 can also be fixed on the backplate 12 by means of bonding, etc.
[0052] A filter screen 4 can be fixed on the inner side of the plug gate frame 2. The filter screen 4 can be bonded or fixed to the inner side of the plug gate frame 2 with screws. The plug gate frame 2 can also be set as a multi-layer structure, and the filter screen 4 can be inserted into the gap of the plug gate frame 2 like the gate plate 3. During use, filter screens 7 with different mesh sizes can be selected according to the drainage requirements.
[0053] Vertical grooves 5 can be provided at the relative positions of the two side plates 13. A mudguard 6 can be inserted into the grooves 5. The height of the mudguard 6 can be selected as different heights according to the water potential. In other embodiments, reserved nuts can also be provided at the relative positions on the two side plates 13, and the mudguard 6 can be fixed to the side plates 13 with screws. The mudguard 6 can intercept the sediment in the water to prevent soil erosion. At the same time, the mudguard 6 is of overflow drainage type, and only the water higher than the mudguard 6 can be filtered out, which can retain the sedimentary fertilizers that have not decomposed in the water, avoiding the waste of fertilizers and environmental pollution.
[0054] Such as Figure 6As shown in the figure, during use, one end of the drain pipe is connected to the water outlet pipe 7 with glass glue, and the other end extends into the drainage ditch. Lift the gate plate 3 to a certain height to expose part or all of the water outlet pipe 7. The water in the farmland flows into the ecological drainage gate from the opening side of the outer frame 1 of the gate. The water flow is first blocked by the mud guard 6, and the sediment in the water settles in front of the mud guard 6. After the water overflows the mud guard 6, it flows into the ecological drainage gate and then into the drain pipe through the water outlet pipe 7. Before the water flow enters the water outlet pipe 7, the filter screen 4 can intercept some floating impurities in the water in the ecological drainage gate to prevent the impurities from flowing into the drainage ditch and causing blockage.
[0055] As Figure 7 shown, this is the second embodiment of the present application.
[0056] In this embodiment, different from the first embodiment, the two side plates 13 may have outwardly protruding portions 8 at opposite positions. The grooves 5 are provided in the protruding portions 8 or at the edges of the protruding portions 8 close to the filter screen 4, and the mud guard 6 is also located in the protruding portions 8 or at the edges of the protruding portions 8 close to the filter screen 4. The two protruding portions 8 cause a change in the water passing area in the outer frame 1 of the gate. After the water flow enters the ecological drainage gate, when passing through the protruding portions 8, due to the widening of the water surface, the water flow velocity slows down, and the sediment and undecomposed bottom fertilizers in the water are more likely to settle. The mud guard 6 can also intercept more sediment and undecomposed bottom fertilizers, reducing soil erosion.
[0057] As Figure 8 shown, this is the third embodiment of the present application.
[0058] In this embodiment, different from the second embodiment, there are two sets of grooves 5 in the protruding portion 8. One set of grooves 5 is located at the edge of the protruding portion 8 close to the filter screen 4, and one set of grooves 5 is located in the middle of the protruding portion 8. The mud guard 6 is inserted into both sets of grooves 5. When the water flow flows in the outer frame 1 of the gate, when it encounters the first mud guard 6, the water flow is blocked, and part of the sediment and undecomposed bottom fertilizers will be intercepted by the first mud guard 6. When the water potential is large or the content of sediment and undecomposed bottom fertilizers in the water is high, part of the sediment and undecomposed bottom fertilizers will still flow over the first mud guard 6 with the water flow. When flowing over the first mud guard 6, the water flow will encounter the second mud guard 6. At this time, an eddy current will be formed under the second mud guard 6. Due to the blockage of the second mud guard 6, the remaining part of the sediment and undecomposed bottom fertilizers will also be blocked and settle. Therefore, the two sets of mud guards 6 can better intercept the sediment and undecomposed bottom fertilizers in the water.
[0059] The heights of the two mud guards 6 can be the same, or along the direction of the water flow, the height of the mud guard 6 increases, which can better play the role of intercepting sediment and undecomposed bottom fertilizers.
[0060] In other embodiments, if the length of the side plate 13 is long enough, the protruding part 8 can be set longer and more mudguards can be arranged therein. Multiple groups of mudguards can better intercept sediment and undecomposed bottom fertilizers in the water, playing a better role in preventing soil erosion.
[0061] The heights of multiple mudguards 6 can be the same, or along the direction of the water flow, the heights of the mudguards 6 increase in sequence, which can better play the role of intercepting sediment and undecomposed bottom fertilizers.
[0062] In other embodiments, in order to reduce the manufacturing cost of the ecological drainage sluice, the protruding part 8 on the side plate 13 can also be omitted. On the basis of the first embodiment, increasing the number of mudguards 6 can also increase the interception effect on sediment and undecomposed bottom fertilizers to a certain extent.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application rather than to limit them. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present application does not depart from the spirit and scope of the technical solutions of the present application, and they should all be covered by the scope of the claims of the present application.
