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, which can replenish soil moisture and groundwater resources and provide the necessary moisture conditions for vegetation growth and ecosystem maintenance; However, when the rainfall intensity is high or the duration is long, the rainwater will wash away the soil on the slope, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment. The rainwater runoff on the slope may carry a large amount of sediment. Existing slope rainwater collection often adopts a water inlet, and a grid plate is installed on the water inlet to allow rainwater to enter the water storage tank and 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. Summary of the invention

[0003] 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.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a rainwater collection and irrigation system for a garden greening project slope, comprising: The water collecting end comprises a water inlet assembly installed on the slope surface, wherein a sediment filtering part is provided in the water inlet assembly; A water storage tank, wherein a plurality of water inlet components are connected to the water storage tank through a drainage channel; 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; The water spray pipe is located at the upper end of the slope, and a water spray head is installed at the top end of the water spray pipe.

[0005] Rainwater is an important source of water resources on hillsides, which can replenish soil moisture and groundwater resources and provide the necessary moisture conditions for vegetation growth and ecosystem maintenance; By collecting rainwater on the hillside during the rainy season, the collected rainwater is used to irrigate the vegetation on the hillside during the dry season, thereby ensuring that the vegetation on the hillside can get sufficient water to ensure growth during the dry season, while reducing the use of municipal water supply or groundwater; However, when the rainfall intensity is high or the duration is long, the rainwater will wash away the soil on the slope, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment. The rainwater runoff on the slope may carry a large amount of sediment. Existing slope rainwater collection often adopts a water inlet, and a grid plate is installed on the water inlet to allow rainwater to enter the water storage tank and 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.

[0006] A foundation pit is excavated on the slope surface, and a water inlet component and a drainage channel are installed in the foundation pit; The water inlet components and drainage channels are installed through the foundation pit to fix the water inlet components and drainage channels, and the water inlet components are arranged on the slope.

[0007] The water inlet assembly includes a concrete component, the concrete component is provided with a water inlet tank body, a sediment filter is installed in the water inlet tank body, a collecting part is installed on the port of the water inlet tank body, a connecting pipe is provided at the bottom of the water inlet tank body, a pipe body is connected to the connecting pipe, and the pipe body is connected to the drainage channel; 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.

[0008] Furthermore, the inner bottom side of the water inlet tank body is a closing structure, and the closing structure is adopted to facilitate the convergence of water flow to the middle part, and the sediment filtering part 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 a filter hole, and the two ends of the first filter plate and the inner wall of the water inlet tank body form a pit, and the concrete component is provided with a circular hole connected to the pit; The water flow entering the water inlet tank 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 tank body, the water flow entering the pits first gathers in the pits. After the gathered water flow increases, it enters the tube body through the filter holes on the top of the first filter plate. As the water flows together in the pit, the incoming silt gradually settles in the pit.

[0009] Furthermore, the circular hole is connected with a sewage pipe, the sewage pipe is inclined, the connection between the sewage pipe and the circular hole is the high end, the other end of the sewage pipe extends out of the slope, and a valve body is installed on the extended end of the sewage pipe; After the valve body installed on the sewage pipe is opened, the silt and accumulated 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 silt.

[0010] Further, the collecting part includes a frame, the frame is installed on the port of the water inlet tank body, the frame includes a U-shaped plate body, the bottom surface of the U-shaped plate body is provided with a through groove connected to the water inlet tank body, the bottom surface of the U-shaped plate body is provided with a mounting frame located outside the through groove, the mounting frame is provided with a second filter plate, and the back surface of the second filter plate and the opening formed by the back surface of the U-shaped plate body are closed by a cover plate; 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 on the two sides of the cover plate are aligned with the bottom of the gap; 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 body is connected to the inside 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.

[0011] 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.

[0012] Furthermore, the water-facing surface of the second filter plate is an arc-shaped surface, and the top end of the second filter plate bulges outward.

[0013] 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 along the arc surface of the second filter plate to both sides, 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 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. Select collection parts with different cross-sectional gaps according to the slope and precipitation surface; 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.

[0014] The present invention has the following beneficial effects: 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.

[0015] (2) In the present invention, water 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 incoming water flow first gathers in the pit. After the gathered water flow increases, it enters the pipe body through the filter holes on the top of the first filter plate. During the process of water flow gathering in the pit, the entered silt gradually settles in the pit. After the valve body installed in the sewage pipe is opened, the silt 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 silt.

[0016] (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 silt to flow to both sides along the arc surface of the second filter plate, thereby avoiding the accumulation of silt on the water-facing surface of the second filter plate, solving the problem of silt accumulation on the water inlet surface and causing blockage of the water inlet surface. The water flow flowing to both sides passes through the formed gap. Since the cross-section of the gap is reduced, the water flow speed passing through the gap is increased, and the water flow that is not intercepted drives the blocked silt to flow downward through the gap, thereby avoiding the silt to remain on the inner side surface of the U-shaped plate body.

[0022] Rainwater is an important source of water resources on hillsides, which can replenish soil moisture and groundwater resources and provide the necessary moisture conditions for vegetation growth and ecosystem maintenance; By collecting rainwater on the hillside during the rainy season, the collected rainwater is used to irrigate the vegetation on the hillside during the dry season, thereby ensuring that the vegetation on the hillside can get sufficient water to ensure growth during the dry season, while reducing the use of municipal water supply or groundwater; However, when the rainfall intensity is high or the duration is long, the rainwater will wash away the soil on the slope, causing soil erosion, reducing soil fertility, affecting vegetation growth and the ecological environment.

Since pits are formed between the two ends of the first filter plate 4 and the inner wall of the water inlet tank body 201, the water flow entering the pits is first gathered in the pits. After the gathered water flow increases, it enters the tube body 14 through the filter holes at the top of the first filter plate 4.
