Description

Technical Field

[0001] The invention relates to the technical field of slope rainwater collection, in particular to a slope rainwater collection and irrigation system for a garden greening project. Background Art

[0002] Rainwater is an important source of water resources on hillsides, replenishing soil moisture and groundwater resources, and providing the necessary moisture conditions for vegetation growth and ecosystem maintenance;

[0003] However, when rainfall intensity is high or duration is long, the rainwater will wash away the soil on the hillside, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment. Rainwater runoff on the hillside may carry a large amount of sediment.

[0004] Existing slope rainwater collection often adopts a water inlet. By installing a grid plate on the water inlet, rainwater can enter the water storage tank to achieve rainwater collection. Since the water flow left from the hillside contains a large amount of leaves and debris, it is easy to cause the surface of the grid plate to be blocked, thereby affecting water inflow. Summary of the Invention

[0005] The purpose of the present invention is to provide a rainwater collection and irrigation system for slopes of landscaping projects to solve the problems raised in the above-mentioned background technology.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a system for collecting and irrigating rainwater on slopes of landscaping projects, comprising:

[0008] The water collection end includes a water inlet assembly installed on the slope surface, wherein the water inlet assembly is provided with a sediment filter;

[0009] A water storage tank, wherein a plurality of water inlet components are connected to the water storage tank through a drainage channel;

[0010] The irrigation end includes a water pump, the water pump is connected to the water tank through a water inlet pipe, the water outlet of the water pump is connected to a water spray pipe, and the water spray pipe extends out of the slope;

[0011] The water spray pipe is located at the upper end of the slope, and a water spray head is installed on the top end of the water spray pipe.

[0012] Rainwater is an important source of water resources on hillsides, replenishing soil moisture and groundwater resources, and providing the necessary moisture conditions for vegetation growth and ecosystem maintenance;

[0013] By collecting rainwater from the hillside during the rainy season and using it to irrigate the vegetation on the hillside during the dry season, the vegetation on the hillside can be guaranteed to have sufficient water to grow, while reducing the use of municipal water supply or groundwater.

[0014] However, when rainfall intensity is high or duration is long, the rainwater will wash away the soil on the hillside, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment. Rainwater runoff on the hillside may carry a large amount of sediment.

[0015] Existing slope rainwater collection often adopts a water inlet. By installing a grid plate on the water inlet, rainwater can enter the water storage tank to achieve rainwater collection. Since the water flow left from the hillside contains a large amount of leaves and debris, it is easy to cause the surface of the grid plate to be blocked, thereby affecting water inflow.

[0016] A foundation pit is excavated on the slope surface, and a water inlet component and a drainage channel are installed in the foundation pit;

[0017] The water inlet components and drainage channels are installed through the foundation pit to complete the fixation of the water inlet components and drainage channels, and the arrangement of the water inlet components on the slope is also completed.

[0018] The water inlet assembly includes a concrete component, the concrete component is provided with a water inlet trough body, a sediment filter is installed in the water inlet trough body, a collection part is installed on the port of the water inlet trough body, a connecting pipe is provided at the bottom of the water inlet trough body, a pipe body is connected to the connecting pipe, and the pipe body is connected to the drainage channel;

[0019] The water gathered on the slope flows along the slope toward the collection part, and part of the water flows into the interior of the collection part and gathers in the drainage channel for collection.

[0020] Furthermore, the inner bottom side of the water inlet trough body is a closed structure, which facilitates the convergence of water flow to the middle. The sediment filter portion includes a first filter plate, the side of the first filter plate is "W"-shaped, and the top of the first filter plate is provided with filter holes. The two ends of the first filter plate and the inner wall of the water inlet trough body form pits, and the concrete component is provided with a circular hole connected to the pit.

[0021] The water flowing into the water inlet tank falls on the surface of the first filter plate. Since the two ends of the first filter plate and the inner wall of the water inlet tank form pits, the incoming water first gathers in the pits. After the gathered water increases, it enters the tube body through the filter holes on the top of the first filter plate.

[0022] As the water flows in the pit, the incoming sediment gradually settles in the pit.

[0023] Furthermore, a sewage pipe is connected to the circular hole, and the sewage pipe is distributed obliquely. The connection between the sewage pipe and the circular hole is the high end, and the other end of the sewage pipe extends out of the slope. At the same time, a valve body is installed on the extended end of the sewage pipe.

[0024] After the valve body installed on the sewage pipe is opened, the mud and water collected in the pit are discharged through the sewage pipe. At the same time, the inclined distribution of the sewage pipe is conducive to the discharge of accumulated water and mud.

[0025] Furthermore, the collecting portion includes a frame, which is mounted on the port of the water inlet trough body, and the frame includes a U-shaped plate body, the bottom surface of the U-shaped plate body is provided with a through groove communicating with the water inlet trough body, and a mounting frame located outside the through groove is mounted on the bottom surface of the U-shaped plate body, and a second filter plate is mounted in the mounting frame, and an opening formed on the back surface of the second filter plate and the back surface of the U-shaped plate body is closed by a cover plate;

[0026] Gaps are formed between the two sides of the second filter plate and the side plates of the U-shaped plate body, and the notches provided on the two sides of the cover plate are aligned with the bottoms of the gaps;

[0027] An inclined plate is installed in the gap, and the cavity formed between the inclined plate and the side plate of the U-shaped plate is connected to the interior of the cover plate. A plurality of filter holes are opened on the inclined plate, and rainwater passing through the filter holes enters the inner side of the cover plate.

[0028] A deep groove is formed between the two water inlet trough bodies, and a fixing nail inserted into the ground is installed in the deep groove.

[0029] Furthermore, the water-facing surface of the second filter plate is an arc-shaped surface, and the top end of the second filter plate is convex outward.

[0030] The collected water flows to the water-facing surface of the second filter plate, and part of the water flows into the interior through the filter holes of the second filter plate. The water that does not enter drives the blocked sediment to flow to both sides along the curved surface of the second filter plate, thereby avoiding sediment accumulation on the water-facing surface of the second filter plate and solving the problem of sediment accumulation on the water inlet surface causing blockage.

[0031] The water flowing to both sides passes through the gap formed. As the cross section of the gap decreases, the water flow speed through the gap increases. The unblocked water flow drives the blocked sediment to flow downward through the gap, preventing the sediment from remaining on the inner side of the U-shaped plate.

[0032] Select collection parts with different cross-sectional gaps according to the slope and precipitation surface;

[0033] In addition, filter holes are also provided on the inclined plate. The water flow and water pressure passing through the gap are increased. The water in the upper layer passes through the filter holes and enters the collection part, and the mud and sand in the lower layer flows out with the water.

[0034] The present invention has the following beneficial effects:

[0035] The rainwater of the present invention is an important source of water resources on the hillside, which can replenish soil moisture and groundwater resources, and provide necessary moisture conditions for vegetation growth and ecosystem maintenance. By collecting rainwater left on the hillside in the rainy season, the vegetation on the hillside is irrigated with the collected rainwater in the dry season, thereby ensuring that the vegetation on the hillside can obtain sufficient moisture in the dry season to ensure growth, while reducing the use of municipal water supply or groundwater.

[0036] (2) In the present invention, the water flow entering the water inlet trough body falls on the surface of the first filter plate. Since pits are formed between the two ends of the first filter plate and the inner wall of the water inlet trough body, the water flow entering the pit first converges into the pit. After the converged water flow increases, it enters the pipe body through the filter holes on the top of the first filter plate. In the process of the water flow converging in the pit, the incoming sediment gradually settles in the pit. After the valve body installed on the sewage pipe is opened, the sediment gathered in the pit and the accumulated water are discharged through the sewage pipe. At the same time, the inclined distribution of the sewage pipe is conducive to the discharge of accumulated water and sediment.

[0037] (3) The water flow collected by the present invention flows toward the water-facing surface of the second filter plate, and part of the water flow enters the interior through the filter holes of the second filter plate. The water flow that does not enter drives the blocked sediment to flow to both sides along the curved surface of the second filter plate, thereby avoiding sediment accumulation on the water-facing surface of the second filter plate, solving the problem of sediment accumulation on the water inlet surface causing blockage of the water inlet surface. The water flow flowing to both sides passes through the gap formed. Since the cross-section of the gap is reduced, the water flow speed passing through the gap increases. The water flow that is not intercepted drives the blocked sediment to flow downward through the gap, thereby avoiding sediment retention on the inner side surface of the U-shaped plate.

[0038] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1-8 As shown, the present invention is a slope rainwater collection and irrigation system for landscaping projects, comprising:

[0053] The water collection end includes a water inlet assembly installed on the slope 1, and a sediment filter is provided in the water inlet assembly;

[0054] A water storage tank 9, wherein a plurality of water inlet components are connected to the water storage tank 9 through a drainage channel 8;

[0055] The irrigation end includes a water pump 11, which is connected to the water tank 9 through a water inlet pipe 10. The water outlet of the water pump 11 is connected to a water spray pipe 12, which extends out of the slope 1;

[0056] The water spray pipe 12 is located at the upper end of the slope 1, and a water spray head is installed at the top of the water spray pipe 12;

[0057] A sprinkler head is installed at the top of the sprinkler pipe 12, and the water flow sprayed out flows downward along the slope 1 to irrigate the vegetation on the slope 1 in the dry season.

[0058] Rainwater is an important source of water resources on hillsides, replenishing soil moisture and groundwater resources, and providing the necessary moisture conditions for vegetation growth and ecosystem maintenance;

[0059] By collecting rainwater from the hillside during the rainy season and using it to irrigate the vegetation on the hillside during the dry season, the vegetation on the hillside can be guaranteed to have sufficient water to grow, while reducing the use of municipal water supply or groundwater.

[0060] However, when rainfall intensity is high or duration is long, the rainwater will wash away the soil on the hillside, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment. Rainwater runoff on the hillside may carry a large amount of sediment.

[0061] Existing slope rainwater collection often adopts a water inlet. By installing a grid plate on the water inlet, rainwater can enter the water storage tank 9 to collect rainwater. Since the water flow left from the hillside contains a large amount of leaves and debris, it is easy to cause the surface of the grid plate to be blocked, thereby affecting water inflow.

[0062] A foundation pit is excavated on the slope 1, and a water inlet assembly and a drainage channel 8 are installed in the foundation pit;

[0063] The water inlet assembly and the drainage channel 8 are installed through the foundation pit to complete the fixing of the water inlet assembly and the drainage channel 8. In addition, the arrangement of the water inlet assembly on the slope 1 is as follows: Figure 2 .

[0064] The water inlet assembly includes a concrete component 2, which is provided with a water inlet trough 201. A sediment filter is installed in the water inlet trough 201. A collection unit is installed on the port of the water inlet trough 201. A connecting pipe 204 is provided at the bottom of the water inlet trough 201. The connecting pipe 204 is connected to the pipe body 14, and the pipe body 14 is connected to the drainage channel 8.

[0065] The water flow gathered on the slope 1 flows along the slope 1 toward the collection part, and part of the water flow enters the interior of the collection part and is gathered in the drainage channel 8 for collection.

[0066] The inner bottom side of the water inlet trough 201 is a closed structure, which facilitates the convergence of water flow to the middle. The sediment filter includes a first filter plate 4. The side of the first filter plate 4 is "W"-shaped. The top of the first filter plate 4 is provided with filter holes. The two ends of the first filter plate 4 and the inner wall of the water inlet trough 201 form a pit. The concrete member 2 is provided with a circular hole 203 connected to the pit.

[0067] The water flowing into the water inlet tank 201 falls on the surface of the first filter plate 4. Since the two ends of the first filter plate 4 and the inner wall of the water inlet tank 201 form pits, the incoming water first gathers in the pits. After the gathered water increases, it passes through the filter holes on the top of the first filter plate 4 and enters the interior of the tube body 14.

[0068] As the water flows in the pit, the incoming sediment gradually settles in the pit.

[0069] The circular hole 203 is connected to a drain pipe 205, which is inclined. The connection between the drain pipe 205 and the circular hole 203 is the high end, and the other end of the drain pipe 205 extends out of the slope 1. A valve body is installed on the extended end of the drain pipe 205.

[0070] After the valve body installed on the sewage pipe 205 is opened, the sediment and accumulated water collected in the pit are discharged through the sewage pipe 205. At the same time, the inclined distribution of the sewage pipe 205 is conducive to the discharge of accumulated water and sediment.

[0071] The collecting portion includes a frame 3, which is mounted on the port of the water inlet trough 201. The frame 3 includes a U-shaped plate 301. The bottom surface of the U-shaped plate 301 is provided with a through groove 303 that communicates with the water inlet trough 201. A mounting bracket 302 is mounted on the bottom surface of the U-shaped plate 301 and is located outside the through groove 303. A second filter plate 5 is mounted in the mounting bracket 302. The opening formed on the back of the second filter plate 5 and the back of the U-shaped plate 301 is sealed by a cover plate 6.

[0072] Gaps 304 are formed between the sides of the second filter plate 5 and the side plates of the U-shaped plate 301, and the notches on both sides of the cover plate 6 are aligned with the bottom of the gaps 304;

[0073] An inclined plate 7 is installed in the gap 304 . The cavity formed between the inclined plate 7 and the side plate of the U-shaped plate body 301 is connected to the interior of the cover plate 6 . A plurality of filter holes are opened on the inclined plate 7 , and rainwater passing through the filter holes enters the inner side of the cover plate 6 .

[0074] A deep groove 202 is formed between the two water inlet trough bodies 201 , and a fixing nail 13 inserted into the ground is installed in the deep groove 202 .

[0075] The water-facing surface of the second filter plate 5 is an arc-shaped surface, and the top end of the second filter plate 5 is convex outward.

[0076] The collected water flows toward the water-facing surface of the second filter plate 5. Part of the water flows through the filter holes of the second filter plate 5 and enters the interior. The water that does not enter drives the blocked sediment to flow along the curved surface of the second filter plate 5 to both sides, thereby preventing sediment from accumulating on the water-facing surface of the second filter plate 5 and solving the problem of sediment accumulation on the water inlet surface causing blockage.

[0077] The water flowing to both sides passes through the gap 304 formed. Since the cross section of the gap 304 is reduced, the water flow velocity through the gap 304 increases. The unblocked water flow drives the blocked sediment to flow downward through the gap 304, preventing the sediment from being retained on the inner side of the U-shaped plate 301.

[0078] Select a collection part with a gap 304 of different cross-sectional sizes according to the slope and the precipitation surface;

[0079] In addition, filter holes are also provided on the inclined plate 7. The water flow and water pressure passing through the gap 304 are increased. The water in the upper layer passes through the filter holes and enters the collection part, and the mud and sand in the lower layer flows out with the water.
