Abstract
Description
Technical Field
[0001] This disclosure relates to the field of farmland irrigation technology, and more specifically, to an irrigation system for sloping farmland. Background Technology
[0002] Sloping farmland refers to dry land distributed on hillsides with poor surface flatness, severe soil erosion, and low crop yields. Its main characteristic is a slope between 6° and 25°. After reclamation, it is generally referred to as sloping farmland. Due to its topography, sloping farmland is not only prone to soil erosion, leading to a decline in farmland quality, but also suffers from problems such as high elevation and low water content, making irrigation difficult. This can lead to seasonal droughts on the slopes, affecting local farmers' income and hindering agricultural development. Utility Model Content
[0003] The purpose of this disclosure is to provide an irrigation system for sloping farmland to improve the utilization rate of natural precipitation and extend the drought resistance time of crops.
[0004] To achieve the above objectives, this disclosure provides an irrigation system for sloping farmland located on a hillside, the irrigation system comprising:
[0005] An interception pool is located at the bottom edge of the mountain and is used to intercept the water flowing down the mountain.
[0006] A filtration tank, connected to the interception tank, is capable of filtering the water flowing out of the interception tank;
[0007] A water storage tank is located on a hillside, with its position higher than the sloping farmland in the vertical direction. The water storage tank includes an outlet pipe that leads to and connects with the sloping farmland.
[0008] A first water supply pipeline is connected at both ends to the filter tank and the water storage tank, respectively. A selectively activated pumping device is connected to the first water supply pipeline, which is used to pump water from the filter tank to the water storage tank.
[0009] Optionally, the filtration pool includes a first sedimentation pool connected to the interception pool, wherein the inlet of the first sedimentation pool is lower in the height direction than the outlet of the first sedimentation pool.
[0010] Optionally, the filtration tank further includes a second sedimentation tank, which is connected to both the first sedimentation tank and the water storage tank.
[0011] Optionally, the irrigation system includes a second water supply pipeline, with its two ends connected to the intercepting pool and the filtration pool, respectively, and the second water supply pipeline is equipped with a filter screen.
[0012] Optionally, the filter screen covers at least one end of the second water supply pipeline that is connected to the intercepting pool.
[0013] Optionally, an openable and closable gate is provided at the end of the second water supply pipeline that is connected to the intercepting pool, for controlling the connection between the second water supply pipeline and the intercepting pool.
[0014] Optionally, the gate includes:
[0015] A door frame is connected to the bottom of the intercepting pool;
[0016] Fasteners are placed on top of the door frame;
[0017] The adjusting rod, one end of which passes through the door frame and is threaded into the fastener; and
[0018] A door panel is connected to the end of the adjusting rod away from the fastener, the fastener being capable of moving the adjusting rod in the height direction, so that the door panel can selectively cover the end of the second water supply pipe.
[0019] Optionally, the intercepting pool includes two guide walls and an intercepting dam for intercepting the water flowing down the mountain. The intercepting dam is located at one end away from the mountain, and the two guide walls are respectively connected to both sides of the intercepting dam to guide the water flowing down the mountain to the intercepting dam.
[0020] Optionally, the water outlet pipe includes:
[0021] Supervisor, extending along the vertical direction;
[0022] Multiple branch pipes, spaced apart on the main pipe, are used to connect the main pipe and the sloping farmland; and

[0024] Optionally, the irrigation system further includes a fertilizer tank connected to the main pipe, the connection point of which is located upstream of the plurality of branch pipes.
[0025] The above technical solution intercepts rainwater and floodwater runoff from the mountainside at lower elevations. The intercepted water is then filtered and transported to a higher-level reservoir for storage. The elevation difference between the reservoir and the sloping farmland allows for direct gravity-based irrigation, thereby improving the utilization rate of natural precipitation and extending the drought resistance period for crops. Furthermore, irrigation can be performed directly using gravitational potential energy, eliminating the need for on-site water collection and enhancing irrigation convenience.

Detailed Implementation
[0032] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0033] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined in relation to the actual arrangement direction of the irrigation system during use, and directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.
[0034] According to one embodiment of this disclosure, such as Figure 1 and Figure 2As shown, an irrigation system for sloping farmland 61 is located on a hillside 6. The irrigation system includes an intercepting pond 1, a filtering pond 2, a storage pond 3, and a first water delivery pipeline 30. The intercepting pond 1 can be located at the bottom edge of the hillside 6, and is used to intercept water flowing down the hillside 6. The filtering pond 2 can be connected to the intercepting pond 1 and can filter the water flowing out of the intercepting pond 1. The storage pond 3 can be located on the hillside 6, and its position is higher than the sloping farmland 61 in the vertical direction. The storage pond 3 includes an outlet pipe 31, which leads to the sloping farmland 61. The two ends of the first water delivery pipeline 30 are connected to the filtering pond 2 and the storage pond 3, respectively. A selectively activated pump is connected to the first water delivery pipeline 30, which pumps water from the filtering pond 2 to the storage pond 3.
[0035] The above technical solution intercepts rainwater and floodwater from the mountainside 6 at a lower elevation, filters the intercepted water, and transports it to a higher-level reservoir 3 for storage. The elevation difference between the reservoir 3 and the sloping farmland 61 is then used to directly irrigate the farmland 61 using gravity, thereby improving the utilization rate of natural precipitation and extending the drought resistance time for crops. Furthermore, irrigation can be performed directly using gravitational potential energy, eliminating the need for on-site water collection and improving irrigation convenience.
[0036] It should be noted that the pumping unit can be selectively activated. A water level line can be set for the filter tank 2. When the water level is higher than the line, the pumping unit can be activated to pump water from the filter tank 2 into the storage tank 3, until the water level falls below the line and then it is shut off. The intercepting pool 1 may include two guide walls and an intercepting dam 11 for intercepting the water flowing down the mountain 6. The intercepting dam 11 is located at the end furthest from the mountain 6. The two guide walls are connected to both sides of the intercepting dam 11. The guide walls can guide the water flowing down the mountain 6 to the intercepting dam 11, which can intercept the water flow, thus allowing the water flowing down the mountain 6 to remain in the intercepting pool 1. Additionally, the intercepting pool 1 can also directly collect rainwater. The intercepting pool 1 can be directly installed on dry land at the bottom of the mountain 6. If a natural river channel exists at the bottom of the mountain 6, it can also be built in the river channel; this disclosure does not limit this.
[0037] Furthermore, such as Figure 1As shown, the filter tank 2 may include a first sedimentation tank 21 connected to the intercepting tank 1. The inlet 211 of the first sedimentation tank 21 is lower than the outlet 212 of the first sedimentation tank 21 in the height direction. The lower position of the inlet 211 facilitates a gentler water flow and prevents splashing. After the water flows from the intercepting tank 1 to the first sedimentation tank 21, sedimentation occurs, and impurities settle to the bottom. The higher position of the outlet 212 effectively improves the quality of the water flowing out of the outlet 212, reducing its sediment content. The filter tank 2 may also include a second sedimentation tank 22, which may be connected to both the first sedimentation tank 21 and the storage tank 3, to perform secondary sedimentation on the water flowing out of the intercepting tank 1, further reducing the sediment content of the irrigation water and preventing damage to crops. The filter tank 2 may also be further equipped with additional sedimentation tanks to improve the filtration effect, but this disclosure does not limit this.
[0038] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the irrigation system includes a second water supply pipeline 4, whose two ends can be connected to an intercepting pool 1 and a filtration pool 2, respectively. The second water supply pipeline 4 is equipped with a filter screen 41. The filter screen 41 can slow down the water flow rate into the filtration pool 2 and also intercept some of the sediment in the water in the intercepting pool 1, reducing the sediment content of the water entering the filtration pool 2, thereby relieving subsequent filtration pressure and improving sedimentation. Here, the second water supply pipeline 4 can be a culvert, i.e., a pipeline buried underground, to reduce the impact on the surface. It can also be conveniently installed nearby if other components need to be added around the intercepting pool 1 and the filtration pool 2.
[0039] Furthermore, such as Figure 1 and Figure 2 As shown, the filter screen 41 covers at least one end of the second water supply pipeline 4 that is connected to the intercepting pool 1, so as to prevent the silt blocked by the filter screen 41 from clogging the second water supply pipeline 4 and affecting the normal operation of the irrigation system.
[0040] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the end of the second water supply pipeline 4 that connects to the intercepting pool 1 can be equipped with an openable and closable gate 42, which is used to control the connection between the second water supply pipeline 4 and the intercepting pool 1, so that the intercepted water can settle in the intercepting pool 1 first, thereby improving the subsequent filtration effect. At the same time, by controlling the opening and closing of the gate 42, the flow rate of the water flowing from the intercepting pool 1 into the filtration pool 2 can be controlled, reducing disturbance to the water flow in the filtration pool 2 and avoiding affecting the filtration effect of the filtration pool 2.
[0041] Furthermore, such as Figure 2As shown, the gate 42 may include a gate frame 421, a fastener 422, an adjusting rod 423, and a gate plate 424. The gate frame 421 can be connected to the bottom of the intercepting pool 1, the fastener 422 can be placed on the top of the gate frame 421, and one end of the adjusting rod 423 can pass through the gate frame 421 and be threaded into the fastener 422. Here, the fastener 422 and the adjusting rod 423 can also be piston cylinders, which is not limited in this disclosure. The gate plate 424 can be connected to the end of the adjusting rod 423 away from the fastener 422. The fastener 422 can drive the adjusting rod 423 to move in the height direction, so that the gate plate 424 can selectively cover the end of the second water supply pipeline 4. In this way, by adjusting the fastener 422 to control the movement of the adjusting rod 423, the gate plate 424 is moved. When the door panel 424 is at the bottom, it can completely cover the inlet of the second water supply pipe 4. At this time, the intercepting pool 1 and the filter pool 2 are not connected. When the adjusting rod 423 moves the door panel 424 upward, the inlet of the second water supply pipe 4 is gradually exposed. At this time, the intercepting pool 1 and the filter pool 2 are connected. As the door panel 424 moves upward, the flow rate of the water from the intercepting pool 1 to the filter pool 2 increases continuously until the door panel 424 moves to the top. At this time, the inlet of the second water supply pipe 4 is fully exposed, and the flow rate of the water from the intercepting pool 1 to the filter pool 2 reaches its maximum.
[0042] According to one embodiment of this disclosure, such as Figure 1 As shown, the water outlet pipe 31 may include a main pipe 311, multiple branch pipes 312, and a water outlet valve. The main pipe 311 may extend along the vertical direction, and the multiple branch pipes 312 may be spaced apart on the main pipe 311 to connect the main pipe 311 and the sloping farmland 61. This facilitates irrigation of different areas of the sloping farmland 61 at different heights, improving the uniformity of irrigation and thus enhancing the irrigation effect. The water outlet valve is closable on the branch pipes 312, allowing independent control of the water consumption of different branch pipes 312 for corresponding areas of the sloping farmland 61, enabling precise irrigation based on the conditions of different areas of the sloping farmland 61 and improving water resource utilization.
[0043] Furthermore, such as Figure 1 As shown, the irrigation system may also include a fertilizer trough 5 connected to the main pipe 311, with the connection point between the fertilizer trough 5 and the main pipe 311 located upstream of multiple branch pipes 312. Fertilizer can be mixed with irrigation water in the outlet pipe 31 before entering the sloping farmland 61, thereby achieving integrated water and fertilizer irrigation, making fertilization more uniform, improving fertilizer utilization, and thus increasing crop yield on the sloping farmland 61.
[0044] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0046] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
