Description

Technical Field

[0001] This utility model relates to the technical field of integrated rainwater harvesting and irrigation devices, specifically to an integrated device for slope runoff reuse and water-saving irrigation based on rainwater harvesting. Background Technology

[0002] Slope runoff refers to the thin, sheet-like or network-like temporary water flow that forms along the surface of a natural slope under the action of gravity when rainfall or snowmelt is not completely absorbed by the surface.

[0003] Patent document CN214676925U discloses a rainwater harvesting irrigation device for gardens, comprising a rainwater harvesting plate spanning two support frames, the plate being inclined at both ends with the middle as its highest point; a water storage tank is located at the bottom, connected to the end of the rainwater harvesting plate via a water inlet pipe; a water pump is located at the bottom of the water storage tank, connected to a water outlet pipe at one end, the other end of which has a retractable rotating nozzle and a drip irrigation head for insertion into the soil. This prior art aims to fully collect, purify, and utilize rainwater, improving rainwater collection efficiency compared to other rainwater harvesting irrigation devices, adding a step for adjusting the pH of the rainwater, considering a simultaneous water and fertilizer management model, and employing both sprinkler and drip irrigation methods to meet the irrigation needs of garden plants and reduce production costs.

[0004] However, there are certain drawbacks. The device lacks a deep filtration design for collected rainwater. Sediment and impurities may clog irrigation pipes or affect plant growth, increasing maintenance costs. Rainwater is directly lost in slope runoff, exacerbating soil erosion. Water-saving irrigation systems (such as drip irrigation) operate independently and are not coupled with runoff collection. Therefore, we propose an integrated device for slope runoff reuse and water-saving irrigation based on rainwater collection. Summary of the Invention

[0005] One of the technical problems this application aims to solve is that the device lacks a deep filtration design for collected rainwater. Mud and impurities may clog irrigation pipes or affect plant growth, increasing maintenance costs. Rainwater is directly lost as runoff on slopes, exacerbating soil erosion. Water-saving irrigation systems (such as drip irrigation) operate independently and are not coupled with runoff collection.

[0006] To address the aforementioned technical problems, this application provides an integrated device for slope runoff reuse and water-saving irrigation based on rainwater harvesting, comprising a water collection channel, an internal connecting component comprising a fixed ring, a water storage cellar at the bottom of the water collection channel, a movable ring fixedly mounted on the top of the fixed ring, a sealing block between the inner cavities of the movable ring and the fixed ring, an arc-shaped filter plate at the top of the water collection channel, and water pumps symmetrically mounted at both ends of the water collection channel.

[0007] In some embodiments, the fixed ring has a first through hole at its bottom, the movable ring has a second through hole on its surface, the movable ring has a second stop block arranged in an array at its bottom, and the movable ring has a rotating handle at both ends of its top.

[0008] In some embodiments, the sealing block has a first stop protruding around its perimeter, and the bottom of the sealing block has a set of reset springs arranged in an array, with the bottom of the reset springs fixedly connected to the bottom of the inner cavity of the fixing ring.

[0009] In some embodiments, one end of the second stop has a sloping groove, the top of the sealing block is higher than the top of the first stop, and the sealing block is engaged with the inside of the second through hole by a return spring.

[0010] In some embodiments, the fixed ring is fixedly connected to the bottom of the partition between the water collection channel and the water storage cellar, and the movable ring is rotatably connected to the top of the partition between the water collection channel and the water storage cellar.

[0011] In some embodiments, the water collection channel is a V-shaped guide channel structure, with water collection troughs at both ends of the top of the water collection channel. A secondary filter plate is provided in the middle of the inner cavity of the water collection channel. The side of the arc-shaped filter plate is provided with grooves and is interconnected with the water collection troughs. Multiple first water pumping pipes are symmetrically arranged at both ends of the inner cavity of the water collection channel. A filter head is provided at one end of each first water pumping pipe. A second water pumping pipe is provided at the bottom of the water pump. The second water pumping pipe passes through the side of the water storage cellar and is placed in the inner cavity of the water storage cellar. Drip irrigation pipes are provided on both sides of the water pump. Multiple micro-sprinklers are provided on the surface of each drip irrigation pipe.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. This utility model sets up a water storage cellar at the bottom of the water collection channel. During rainfall, the arc-shaped filter plate at the top of the water collection channel initially filters out larger impurities on the surface. After entering the interior of the water collection channel, the rainwater is filtered again by the secondary filter plate and then transported to the external irrigation structure through the first pumping pipe. When the rainfall is heavy, the movable ring is rotated, causing the stop block at the bottom of the movable ring to squeeze and drive the sealing block out of the interior of the second through hole, connecting the second through hole and the first through hole, allowing the rainwater to enter the interior of the water storage cellar for storage. The water storage cellar is directly connected to the drip irrigation network, reducing the energy consumption of water lifting.

[0014] 2. This utility model allows direct use of the water stored inside the water storage cellar by setting a second water pump around the cellar. At the same time, the water pump is connected to the inner cavity of the water collection channel through the first water pump, which can select water sources for irrigation in different areas according to the amount of rainfall, thereby improving the flexibility of irrigation water use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: an integrated device for slope runoff reuse and water-saving irrigation based on rainwater harvesting, including a water collection channel 1. The water collection channel 1 has a connecting component 2 inside, which includes a fixed ring 21. A water storage cellar 102 is located at the bottom of the water collection channel 1. A movable ring 24 is fixedly installed at the top of the fixed ring 21. A sealing block 22 is installed between the movable ring 24 and the inner cavity of the fixed ring 21. An arc-shaped filter plate 3 is installed at the top of the water collection channel 1. Water pumps 7 are symmetrically installed at both ends of the water collection channel 1. The water storage cellar 102 at the bottom of the water collection channel 1, during rainfall, uses the arc-shaped filter plate 3 at the top of the water collection channel 1 to initially filter larger impurities on the surface, allowing rainwater to enter the inner cavity of the water collection channel 1. After being filtered again by the secondary filter plate 5, the water is transported to the external irrigation structure through the first pumping pipe 4. When the rainfall is heavy, the movable ring 24 is rotated, causing the second stop 241 at the bottom of the movable ring 24 to squeeze the first stop 23, which in turn causes the sealing block 22 to disengage from the interior of the second through hole 240, connecting the second through hole 240 with the first through hole 210, allowing the rainwater to enter the interior of the water storage cellar 102 for storage. The water storage cellar 102 is directly connected to the drip irrigation network, reducing the energy consumption of water lifting. The sealing block 22 between the fixed ring 21 and the movable ring 24 can be manually rotated to connect the channel between the water collection channel 1 and the bottom water storage cellar 102, allowing the rainwater to enter the interior of the water storage cellar 102 for storage.

[0024] Please see Figure 2 , 4 -5. The bottom of the fixed ring 21 has a first through hole 210, and the surface of the movable ring 24 has a second through hole 240. The bottom of the movable ring 24 has second stops 241 arranged in an array. The top of the movable ring 24 has rotating handles 25 at both ends. One end of the second stop 241 has a beveled groove. The top of the sealing block 22 is higher than the top of the first stop 23. The sealing block 22 is engaged with the inside of the second through hole 240 by a return spring 26. The first stop 23 protrudes around the sealing block 22. The bottom of the sealing block 22 has return springs 26 arranged in an array. The bottom of the return springs 26 is fixedly connected to the bottom of the inner cavity of the fixed ring 21. The fixed ring 21 is fixedly connected to the bottom of the partition between the water collection channel 1 and the water storage cellar 102. The movable ring 24 is rotatably connected to the top of the partition between the water collection channel 1 and the water storage cellar 102. The inclined surface at one end of the second stop 241 allows the first stop 23 to gradually move downward, causing the sealing block 22 to disengage from the inside of the second through hole 240. The return spring 26 is used to ensure that the sealing block 22 is always locked inside the second through hole 240 when the movable ring 24 rotates to the bottom stop, where the second stop 241 and the first stop 23 are staggered and will not squeeze the first stop 23, thus isolating the water collection channel 1 and the water storage cellar 102.

[0025] Please see Figure 2-3The top and two ends of the water collection channel 1 are provided with water collection troughs 100. The water collection channel 1 has a V-shaped guide channel structure. A secondary filter plate 5 is provided in the middle of the inner cavity of the water collection channel 1. The side of the arc-shaped filter plate 3 is provided with grooves and is interconnected with the water collection trough 100. Multiple first water pumping pipes 4 are symmetrically arranged at both ends of the inner cavity of the water collection channel 1. A filter head 400 is provided at one end of the first water pumping pipe 4. A second water pumping pipe 6 is provided at the bottom of the water pump 7. The second water pumping pipe 6 passes through the side of the water storage cellar 102 and is placed in the inner cavity of the water storage cellar 102. Drip irrigation pipes 8 are provided on both sides of the water pump 7. Multiple micro-sprinklers 9 are provided on the surface of the drip irrigation pipes 8. Since the arc-shaped filter plate 3 is The rainwater is curved, and the impurities carried by the rainwater slide from the top of the curved filter plate 3 to both ends into the water collection tank 100. After the rainwater enters the water collection channel 1, the impurities are filtered a second time by the secondary filter plate 5. The first water pumping pipe 4 is equipped with a filter head 400 at one end, which is placed below the secondary filter plate 5 to extract the filtered rainwater. The water pump 7 draws the rainwater from the inside of the water collection channel 1 and irrigates the crops through the drip irrigation pipe 8 and the micro sprinkler 9. The irrigation system is mainly based on drip irrigation through the drip irrigation pipe 8 and supplemented by micro-spraying through the micro sprinkler 9. The surface of the drip irrigation pipe 8 is equipped with an anti-freeze layer. The irrigation volume is dynamically adjusted by combining the soil moisture sensor with the Internet of Things gateway.
