Description

Technical Field

[0001] This invention relates to the field of farmland wastewater treatment technology, specifically to an ecological interception ditch for farmland wastewater. Background Technology

[0002] Ecological ditch technology is similar to the currently widely used artificial wetland wastewater treatment technology. Nitrogen and phosphorus nutrients in farmland drainage in the ditch are intercepted in various forms, such as adsorption, absorption, sedimentation, filtration and microbial degradation, under the combined action of aquatic plants and microorganisms in the ditch bottom sediment.

[0003] Patent document CN110629736B discloses a nitrogen and phosphorus interception system for dryland farmland based on ecological ditch technology and its application. The system includes an ecological ditch, buffer weirs, and interception components. The ecological ditch comprises ditch walls and a ditch bottom. Two ditch walls are provided, which are snapped onto the ditch bottom, forming an inverted trapezoidal structure. Two buffer weirs are provided, each inclinedly mounted on one of the two ditch walls. A horizontal retaining wall is provided on the buffer weir, and a flow passage is provided on the retaining wall. This application effectively intercepts suspended pollutants in farmland drainage by setting an interception grid at the system's inlet, preventing suspended pollutants from clogging subsequent treatment units and improving the system's stability.

[0004] In the prior art of the aforementioned patent documents, suspended pollutants in farmland drainage are effectively intercepted by setting an interception bar at the system inlet. However, as the interception process progresses, the blocked suspended matter will gradually accumulate to an excessive amount, eventually clogging the interception bar. In fact, as the blockage becomes too large, it may even overflow the interception bar, affecting the sewage treatment effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an ecological interception ditch for farmland sewage, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an ecological interception ditch for farmland sewage, comprising a ditch base, an interception frame fixedly installed at the end of the ditch base, an interception net fixedly installed inside the interception frame, and a treatment tank opened inside the ditch base;

[0007] It also includes a conveying module, which includes an electric push rod fixedly installed on the top of the interception frame. A slide is fixedly installed on the output shaft of the electric push rod, and a conveying component is fixedly installed on the slide. When the interception net intercepts debris, the conveying module can guide the debris to the processing tank for processing, thus preventing the debris from accumulating continuously.

[0017] In the above technical solution, the beneficial effects of the present invention are as follows: by activating the electric push rod, the slide can be moved. The slide is V-shaped, and its outwardly extending half is a one-way flap. When the slide moves towards the processing tank, it is V-shaped, which can collect the debris into the processing tank and improve the debris processing efficiency.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1: Please refer to Figures 1 to 4 , Figure 6 and Figure 9 The present invention provides a technical solution: an ecological interception ditch for farmland sewage, including a ditch base 1, an interception frame 11 fixedly installed at the end of the ditch base 1, an interception net 12 fixedly installed inside the interception frame 11, and a treatment tank 16 opened inside the ditch base 1.

[0032] It also includes a conveying module, which includes an electric push rod 13 fixedly installed on the top of the interception frame 11. A slide 14 is fixedly installed on the output shaft of the electric push rod 13, and a conveying component 15 is fixedly installed on the slide 14. When the interception net 12 intercepts debris, the conveying module can guide the debris to the processing tank 16 for processing, so as to avoid the continuous accumulation of debris.

[0033] An interceptor plate 2 is fixedly installed on the side of the interceptor frame 11 near the processing tank 16. A first rack 21 is fixedly installed at the end of the output shaft of the electric push rod 13. A first gear 22 is meshed on one side of the first rack 21. A guide wheel 23 is fixedly installed at the bottom of the first gear 22.

[0034] Specifically, the interception net 12 is inclined towards the treatment tank 16. When the interception net 12 intercepts debris, the debris can be flushed into the treatment tank 16 by the impact of the water flow, preventing the debris from clogging and accumulating in front of the interception net 12. The slide 14 can be moved by activating the electric push rod 13. The slide 14 is V-shaped, and its outward half is a one-way flap. When the slide 14 moves towards the treatment tank 16, it is V-shaped, which can collect the debris into the treatment tank 16 and improve the efficiency of debris treatment.

[0035] Furthermore, farmland environments are complex, and the water flow can easily contain grain twigs or dead branches from trees near the farmland. When dead branches are present in the debris, they can easily obstruct other debris. In this invention, when the first rack 21 moves, it drives the first gear 22 to rotate. When the first gear 22 rotates, it drives the guide wheel 23 to rotate. An arc-shaped guide plate can be provided on the outer periphery of the guide wheel 23, as shown in the attached specification. Figure 9 As shown, when the guide wheel 23 rotates clockwise, it can carry the debris into the processing tank 16. When it rotates counterclockwise during the reset process, its arc-shaped smooth surface can prevent the debris from being carried out of the processing tank 16 again. A break rod 24 is also fixedly installed on one side of the guide wheel 23 to cooperate with the guide wheel 23, which can break the debris such as dead wood, reducing the obstruction of the debris by the excessive length of the dead wood.

[0036] Example 2: Please refer to Figures 1 to 4 , Figure 7 and Figure 8 A second gear 3 is provided below the first gear 22. A second rack 31 is meshed on one side of the second gear 3. A connecting rod 32 is fixedly installed at the bottom of the second rack 31. A pressing plate 33 is fixedly installed at the bottom of the connecting rod 32.

[0037] It also includes a processing component, which includes a drive module and an output module. The drive module includes a third gear 35 that meshes with the second rack 31. A gearbox 36 is disposed above the third gear 35. A first wheel 37 is fixedly installed at the output end of the gearbox 36. A drive belt 38 is driven to the outer surface of the first wheel 37. A second wheel 39 is driven to the other side of the drive belt 38.

[0038] The export module includes a lead screw 310 fixedly installed at the bottom of the second rotating wheel 39. A top block 311 is spirally connected to the outer surface of the lead screw 310. A telescopic sleeve 312 is movably installed on the outer surface of the top block 311. A collection groove 313 is provided on one side of the ditch base 1, and an export groove is provided above the top block 311.

[0039] Based on Embodiment 1, the guide wheel 23 is formed by integrating several guide wheels 23 through a round rod. The top of the round rod is fixedly installed with the first gear 22, and a second gear 3 is also fixedly installed on the outer surface of the upper side of the round rod. When the first gear 22 rotates, it can drive the second rack 31 to rotate. The second rack 31 can drive the connecting rod 32 to move, so that the connecting rod 32 drives the extrusion plate 33 to move. The extrusion plate 33 extrudes the debris in the processing tank 16, squeezing the debris together for subsequent processing. A return spring 34 is fixedly installed on the surface of the extrusion plate 33 for resetting and continuous extrusion. When the second rack 31 moves, it will drive the first gear 22 to move. The rotation of the three gears 35 drives the first rotating wheel 37 to rotate via the gearbox 36, increasing the rotational speed of the first rotating wheel 37. The first rotating wheel 37 drives the transmission belt 38, which in turn drives the second rotating wheel 39 to rotate. The second rotating wheel 39 drives the lead screw 310 to rotate, causing the lead screw 310 to lift the top block 311. When the waste in the processing tank 16 is nearly full, the top block 311 will lift the waste upwards, allowing it to enter the collection tank 313 from the discharge tank, thus collecting the squeezed waste. In this way, more waste can be collected. A fence 314 is also fixedly installed around the discharge tank to prevent waste from leaking out.

[0040] Example 3: Please refer to Figures 1 to 8 A bidirectional electric push rod 4 is fixedly installed on the top of the interception frame 11. A connecting rod 41 is movably installed on the output shaft of the bidirectional electric push rod 4. A water control gate 42 is movably installed on the other end of the connecting rod 41.

[0041] A positioning block 5 is fixedly installed on one side of the water control gate 42, and a positioning frame 51 is movably installed on the outer surface of the positioning block 5. The positioning frame 51 is fixedly installed on the top of the interception frame 11.

[0042] Planting troughs 6 are provided on both sides of the ditch base 1. An installation trough 7 is provided on one side of the planting trough 6. A flow-blocking plate 71 is movably installed inside the installation trough 7. A flow-blocking groove 72 is provided in the middle of the flow-blocking plate 71.

[0043] The water control gate 42 is fixedly installed with a third rack 73 on both sides. A fixing plate 74 is fixedly installed on the ditch base 1. A fourth gear 75 is movably installed on the fixing plate 74. A gathering wheel 76 is fixedly installed on one side of the fourth gear 75. A thin rope 77 is connected to the gathering wheel 76.

[0044] Both sides of the flow deflector 71 are provided with flow guide grooves 8, and the inside of the flow guide grooves 8 is rotatably connected to the protective plate 81 by a torsion spring.

[0045] During heavy rains, the water flow in farmland is greater. When the flow velocity is too high, the sedimentation effect of the ditch base 1 is lower. In this invention, by activating the bidirectional electric push rod 4, the connecting rod 41 can be driven, causing the connecting rod 41 to move the water control gate 42 downward, thereby blocking the interception net 12, controlling the water flow, and planting plants in the planting trough 6 to adsorb nitrogen and phosphorus nutrients in the water. When the water control gate 42 descends, it will drive the third rack 73 to descend, causing the third rack 73 to drive the fourth gear 75, which in turn drives the gathering wheel 76 to rotate. At this time, the gathering wheel 76 will gather the thin rope 77, which is fixedly connected to the flow-blocking plate 71, causing the flow-blocking plate 71 to flip, thereby blocking the water flow and reducing the water flow velocity. The flow-blocking groove 72 can also cooperate to slow down the water flow, thereby improving the sedimentation effect, as shown in the attached instruction manual. Figure 5 As shown; furthermore, when the water flow speed is too fast, its impact force can cause problems such as breakage of plants. In this invention, when the flow-blocking plate 71 is flipped, it can reduce the water flow speed and provide protection for the plants. At the same time, when the water flow impacts the flow-blocking plate 71, it will break open the protective plate 81 and flow out from the guide channel 8. At this time, the water flow will be guided by the protective plate 81 to the middle of the ditch base 1, avoiding the water flow from directly impacting the plant roots and achieving the purpose of protecting the plants. The positioning block 5 and the positioning frame 51 can position the water control gate 42 and share the pressure of the water flow. Preferably, this invention can be set at the end of the ditch or in the body of the ditch, which can improve the effects of sedimentation, flow control and plant protection.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
