Description

Technical Field

[0001] This invention belongs to the field of rainwater harvesting technology, specifically a rainwater harvesting system and method adapted for greenhouses. Background Technology

[0002] As the core facility of facility agriculture, greenhouses need to be designed to meet the environmental needs of different seasons: during the rainy season, they need to efficiently collect clean rainwater to reduce irrigation costs, and during the winter, they need to reliably fix straw curtains to ensure heat preservation.

[0003] While existing rainwater harvesting systems have basic diversion functions, they lack a diversion mechanism. Initial rainwater carries pollutants such as dust, pesticide residues, and bird droppings accumulated on the roof surface. Direct collection of this water would severely contaminate the water storage devices and affect irrigation water quality.

[0004] Existing rainwater harvesting systems can only be used during the rainy season and are generally idle in winter. Meanwhile, existing greenhouses require straw mats for insulation during winter or seasons with significant diurnal temperature variations. The bottom of these straw mats is typically secured using independent ground anchors, which are time-consuming, labor-intensive, and prone to loosening. Therefore, it is evident that existing technologies treat rainwater harvesting and greenhouse insulation systems as independent entities, lacking integrated functional design. This results in single-function equipment, resource waste, and high installation and maintenance costs, which does not align with the intensive development strategy for greenhouses.

[0005] Therefore, it is necessary to make improvements to address the aforementioned issues. Summary of the Invention

[0006] This invention aims to at least partially solve one of the technical problems in related technologies, and to this end, proposes an intensive rainwater harvesting system and method adapted for greenhouses. This invention utilizes the inclined surface of the box lid to guide rainwater during the rainy season, and uses the box lid to hold and fix the straw mat in winter, forming a multi-functional integrated design. This not only improves rainwater harvesting efficiency and water quality safety, but also reduces greenhouse equipment redundancy through functional integration, enhances overall wind resistance, and provides technical support for the intensive upgrading of facility agriculture.

[0007] The technical solution is as follows:

[0008] On one hand, this invention proposes an intensive rainwater harvesting system adapted for greenhouses, including a greenhouse body, which includes a front wall, a rear wall, and side walls. The top of the greenhouse body is provided with a frame, and the frame is covered with a roof. At least one set of diversion components is also provided on the front side of the front wall. The diversion component includes a box with an opening, and there is a gap between the box and the front wall to form a flow channel. The top of the box is provided with a flip-up box cover, which can be fastened to the top of the box to form a closed state. When the box cover is flipped, the box cover is tilted, one end of the box cover is connected to the front wall, and the projection of the other end of the box cover is located in the opening area of ​​the top of the box, forming a guide section for guiding rainwater flowing down the roof into the box. One end of the box is connected to a collector pipe, and the other end of the collector pipe is connected to a water storage device.

[0009] Preferably, a flipping mechanism is provided between the lid and the body of the box. The flipping mechanism includes a first arm and a second arm. One end of the first arm is hinged to the side wall of the lid, and the other end is hinged to the side wall of the body. One end of the second arm is hinged to the side wall of the lid. The mechanism also includes an active arm, which is hinged to the body of the box. The other end of the second arm is hinged to one end of the active arm. An electric actuator is also hinged to the side wall of the body of the box, and the other end of the electric actuator is hinged to the other end of the active arm. The mechanism also includes a connecting rod, one end of which is hinged to the active arm, and the other end of which is hinged to one end of the first arm. The length of the second arm is greater than the length of the first arm.

[0010] Preferably, it also includes a protective shell, which is connected to the side wall of the box body, and a sandwich is formed between the protective shell and the side wall of the box body. The top of the sandwich is an open structure, and the flipping mechanism is disposed in the sandwich.

[0011] Preferably, the first arm is fixedly connected to a first lug, the active arm is fixedly connected to a second lug, and the two ends of the connecting rod are respectively hinged to the first lug and the second lug.

[0012] Preferably, the front wall has a groove, and when the box cover is flipped over, one end of the box cover can be inserted into the groove.

[0013] Preferably, it also includes a controller and a rain sensor, with the controller electrically connected to the electric actuator and the rain sensor respectively.

[0014] Preferably, the shed surface is covered with straw curtains, a rolling shutter machine is installed on the rear wall of the shed, the top of the straw curtain is connected to the rolling shutter machine, and the bottom of the straw curtain extends to the bottom of the groove; one end of the box cover can press and fix the bottom of the straw curtain in the groove.

[0015] Preferably, the end of the box cover near the front wall has several spaced rope holes, and a U-shaped rib is also provided on the upper surface of the box cover; a pressing rope is provided on the canopy surface, one end of the pressing rope is connected to the steel bar hook on the rear wall, and the other end passes through the rope hole and is connected to the U-shaped rib.

[0016] Preferably, the box cover is also provided with a rope tensioner, and the box cover is provided with a number of spaced threaded holes, in which bolts are threadedly connected, and the bottom of the bolts is rotatably connected to a clip, which can be locked onto the pressure film rope.

[0017] On the other hand, the present invention also proposes a method for using an intensive rainwater harvesting system adapted to greenhouses, including a rainwater harvesting mode and a straw curtain fixing mode, the specific process of which is as follows:

[0018] A. The rainwater harvesting mode is used as follows:

[0019] When it is not raining, the lid is fastened to the top of the container to form a closed state, preventing garbage and impurities from entering the container;

[0020] When it starts to rain, keep the lid closed for a time T. The initial rainwater flows down the edge of the roof and is guided away through the flow channel. The initial rainwater cannot enter the box, thus achieving the diversion of the initial rainwater.

[0021] After the rainwater is diverted, the control box cover is flipped to tilt the box, with one end of the cover connected to the front wall to form a guide section. In the middle and later stages, clean rainwater flows down the roof and enters the box after being guided by the guide section. The clean rainwater then flows into the water storage device through the collection pipe.

[0022] B. The method for using the straw mat fixing mode is as follows:

[0023] In winter, the roof needs to be covered with straw mats for insulation. The straw mats are rolled up using a rolling machine, with the bottom of the straw mats extending below the groove.

[0024] The control box lid flips over, pressing one end of the lid against the straw mat until the straw mat is positioned and fixed in the groove by the lid, thus securing the bottom of the straw mat and preventing it from being lifted up by strong winds.

[0025] The above technical solution has the following advantages:

[0026] 1. The present invention uses a designed diversion component to keep the cover closed during the initial rainy period, allowing rainwater to flow along the edge of the roof into the flow channel between the front wall and the box, and directly discharge it to the outside of the roof, thus preventing polluted water from entering the collection system. After the initial rainwater is discharged, the cover flips and tilts to guide the clean rainwater in the middle and later stages into the box, thus achieving the collection of clean rainwater.

[0027] 2. The diversion component in this invention has two states. When the cover is tilted, it forms a "drainage slope" that allows rainwater from the roof to flow quickly into the box, reducing splashing and loss. When it is not raining, the cover is closed to seal the box, preventing leaves, dust and other debris from entering, keeping the inside clean and providing favorable conditions for collecting clean rainwater.

[0028] 3. The present invention has a pre-set groove on the front wall of the greenhouse. After the box cover is flipped over, the end is inserted into the groove. Firstly, it facilitates drainage and prevents rainwater from flowing away through the gap between the box cover and the front wall, thus avoiding waste. Secondly, after the straw mat is rolled up in winter, the bottom end can be embedded in the slot, which, together with the box cover, can effectively fix the straw mat.

[0029] 4. In this invention, when the water diversion component is used to fix the straw mat, the function of fixing the straw mat is integrated into the existing rainwater harvesting system by designing rope holes, U-shaped ribs, pressure ropes, and rope tensioners. This eliminates the need for separate construction and saves on the procurement, installation, and maintenance costs of traditional ground anchors. This "killing two birds with one stone" design achieves collaborative operation and functional integration. Functional integration reduces equipment redundancy in the greenhouse, enhances overall wind resistance, and solves the problem of single-function traditional systems. Attached Figure Description

[0048] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0049] Example 1:

[0050] like Figure 1 - Figure 9As shown, this embodiment proposes an intensive rainwater collection system adapted to greenhouses, including a greenhouse body, which includes a front wall 1, a rear wall 2 and a side wall 3, which together support the frame; the top of the greenhouse body is provided with a frame 4, and the frame 4 is covered with a roof 5, and the top frame 4 and the roof 5 constitute a "roof".

[0051] At least one set of diversion components 6 is also provided on the front side of the front wall 1. The diversion components 6 are fixed to the ground and can be fixed by anchor bolts 16 or expansion bolts 16. In this embodiment, multiple sets of diversion components 6 are provided, and each diversion component 6 is connected in a row. Adjacent diversion components 6 are connected in series through a connecting pipe. The diversion component 6 includes a box 61 with an opening. The box 61 can be a rectangular structure. There is a gap between the box 61 and the front wall 1 to form a flow channel 8. Before installing the diversion components 6, the ground in front of the front wall 1 needs to be hardened to facilitate the installation and fixing of the box 61 and to facilitate the flow of water in the flow channel 8.

[0052] The top of the container 61 is equipped with a flip-up lid 62, which can be fastened to the top of the container 61 to form a closed state. When the lid 62 is flipped, it is tilted, with one end connected to the front wall 1, and the projection of the other end of the lid 62 located in the opening area at the top of the container 61, forming a guide section to guide rainwater flowing down from the roof 5 into the container 61. In other words, after the lid 62 is flipped and tilted, it must be able to ensure that rainwater flows smoothly into the container 61 along the lid 62. One end of the container 61 is connected to a manifold 9, and the other end of the manifold 9 is connected to a water storage device 10. The collected rainwater is collected through the manifold 9 and flows into the water storage device 10 for storage. The water storage device 10 can be an underground water tank or a reservoir, etc.

[0053] In this embodiment, the front wall 1 is a low wall on the sunny side of the greenhouse, usually constructed of brick, concrete, or earthen walls. It serves as a foundation support and reduces the direct intrusion of cold air from the ground into the greenhouse. The rear wall 2 is the main wall on the shaded side of the greenhouse. The interior of the wall may be filled with insulation cotton, polystyrene board, or other materials, while the exterior is plastered with cement or covered with insulation boards to reduce heat loss at night. A crossbeam or steel pipe is installed at the top of the rear wall 2 to fix equipment such as the rolling shutter machine 15 and straw curtain rollers. The wall surface may also have pre-installed steel hooks for connecting the pressing rope 13. The side walls 3 connect the front wall 1 and the rear wall 2, forming the two sides of the greenhouse, with their height transitioning with the front and rear walls 2. The top frame 4 is the "backbone" supporting the greenhouse roof 5, usually constructed with hot-dip galvanized steel pipes, aluminum alloy profiles, or bamboo poles, and designed in different shapes depending on the type of greenhouse. The canopy 5 covering the frame 4 is the "outer garment" of the greenhouse, mainly made of aging-resistant plastic film, glass or polycarbonate panels, which can both ensure light transmission and prevent wind and rain.

[0054] The specific structure that enables the flipping between the lid 62 and the body 61 is as follows:

[0055] A flipping mechanism is provided between the lid 62 and the body 61. The flipping mechanism includes a first arm 63 and a second arm 64. One end of the first arm 63 is hinged to the side wall of the lid 62, and the other end is hinged to the side wall of the body 61. One end of the second arm 64 is hinged to the side wall of the lid 62. It also includes an active arm 65, which is hinged to the body 61. The hinge point is located near the middle of the active arm 65, forming a "lever" fulcrum structure. The other end of the second arm 64 is hinged to one end of the active arm 65. An electric push rod 69 is also hinged to the side wall of the body 61. The other end of the electric push rod 69 is hinged to the other end of the active arm 65. It also includes a connecting rod 68, one end of which is hinged to the active arm 65, and the other end is hinged to one end of the first arm 63. The function of the connecting rod 68 is to simultaneously pull the first arm 63 to swing when the active arm 65 rotates, ensuring that the movements of the first arm 63 and the second arm 64 are coordinated and consistent, and preventing the cover 62 from getting stuck due to uneven force.

[0056] In this embodiment, the length of the second arm 64 is greater than the length of the first arm 63, so as to ensure that the lid 62 can be tilted after being flipped over.

[0057] Working principle of the flipping mechanism:

[0058] Initial state: The lid 62 is fastened to the top of the box body 61, the electric actuator 69 is in a retracted state, the active arm 65 is in a horizontal position, and the first arm 63 and the second arm 64 are folded into a stowage position. Initiation of tilting: The electric actuator 69 is energized and extends, pushing the active arm 65 to rotate counterclockwise around the central pivot point. Because the second arm 64 is longer, the end of the lid 62 connected to it is lifted faster and to a greater extent, while the first arm 63, being shorter, is lifted to a smaller extent. This difference in arm length creates a differential lifting effect, causing the lid 62 to naturally tilt towards one side of the box body 61. Simultaneously, the active arm 65, through the connecting rod 68, drives the first arm 63 to swing synchronously, ensuring a smooth and uninterrupted tilting process.

[0059] It also includes a protective shell 610, which is connected to the side wall of the housing 61, forming a sandwich between the protective shell 610 and the side wall of the housing 61. The top of the sandwich is open, and the flipping mechanism is located in the sandwich. The protective shell 610 is made of hot-dip galvanized steel sheet and is rigidly connected to the side wall of the housing 61 by welding or bolting. The sandwich formed completely covers the first support arm 63, the second support arm 64, the active arm 65, the connecting rod 68 and other flipping mechanisms, which does not hinder the flipping of the housing cover 62, and forms a physical barrier to extend the service life of the flipping mechanism.

[0060] In this embodiment, the first arm 63 is fixedly connected to the first ear seat 66, the active arm 65 is fixedly connected to the second ear seat 67, and the two ends of the connecting rod 68 are respectively hinged to the first ear seat 66 and the second ear seat 67.

[0061] Considering that after the lid 62 is flipped over, there is a gap between the edge of the lid 62 and the front wall 1, which is not conducive to rainwater collection, a groove 7 is also provided in the front wall 1. When the lid 62 is flipped over, one end of the lid 62 can be inserted into the groove 7. The design of the groove 7 allows one end of the lid 62 to be inserted into the groove 7, filling the gap and facilitating the collection of rainwater.

[0062] To achieve intelligent control, the entire system also includes a controller and a rain sensor. The controller is electrically connected to the electric actuator 69 and the rain sensor, respectively. The rain sensor is installed on the main body of the greenhouse or the box 61. The controller can receive signals from the rain sensor and control the electric actuator 69 to move.

[0063] The system is also equipped with relays, and the controller is connected to the relays for control.

[0064] This embodiment also proposes a method for using an intensive rainwater harvesting system adapted to greenhouses, including a rainwater harvesting mode, the specific process of which is as follows:

[0065] A. The rainwater harvesting mode is used as follows:

[0066] When it is not raining, the lid 62 is fastened to the top of the container 61, forming a closed state to prevent garbage and impurities from entering the container 61; specifically, when the rain sensor detects no rain signal, the controller cuts off the power to the electric push rod 69 through the relay, and the lid 62 is fastened to the top of the container 61 under the action of gravity and the pulling force of the first arm 63 and the second arm 64.

[0067] When it starts to rain, the lid 62 is kept in the closed state for a time T. The initial rainwater flows down along the edge of the canopy 5 and is guided away through the flow channel 8. The initial rainwater cannot enter the box 61, thus achieving the diversion of the initial rainwater.

[0068] Specifically, when the rain sensor detects a rainfall signal, the controller starts a timer while keeping the relay de-energized and maintaining the closed cover 62. Initially, rainwater carrying pollutants from the roof 5 flows naturally along the edge of the roof 5 through the flow channel 8 between the front wall 1 and the box 61 to the drainage ditch outside the greenhouse, achieving physical isolation. The diversion time T can be adaptively adjusted by the controller. In this embodiment, the default T = 10-15 minutes, but users can adjust it according to different regional conditions.

[0069] After the rainwater is diverted, the control box cover 62 is flipped so that the box cover 62 is tilted. One end of the box cover 62 is connected to the front wall 1 to form a guide section. In the middle and later stages, the clean rainwater flows down the roof surface 5 and enters the box body 61 after being guided by the guide section. The clean rainwater flows into the water storage device 10 through the manifold 9 for storage.

[0070] Specifically, after the timer reaches T, the controller outputs a signal via a relay, energizing and extending the electric push rod 69, which drives the tilting mechanism to tilt the cover 62. At this time, one end of the cover 62 inserts into the groove 7 of the front wall 1, forming a guide slope connecting with the canopy surface 5. During the later stages, rainwater flows along the canopy surface 5 → cover 62 → opening of the tank body 61, and flows by gravity through the manifold 9 to the water storage device 10. It should be noted that a stainless steel filter screen can be installed at the inlet of the manifold 9 to filter out remaining fine impurities. The controller receives rainwater sensor signals in real time. If rainfall stops, after a 10-minute delay, it controls the electric push rod 69 to reverse, and the cover 62 resets and closes.

[0071] Application results:

[0072] The present invention uses a designed diversion component 6. In the early stage of rain, the cover 62 is kept closed, and the rainwater flows along the edge of the canopy surface 5 into the flow channel 8 between the front wall 1 and the box body 61, and is directly discharged to the outside of the canopy, avoiding the entry of polluted water into the collection system. After the initial rainwater is discharged, the cover 62 is flipped and tilted to guide the clean rainwater in the middle and later stages into the box body 61, so as to achieve the collection of clean rainwater.

[0073] Example 2:

[0074] like Figures 10-15 As shown, based on embodiment 1, the roof 5 is covered with a straw curtain 14, and a rolling shutter machine 15 is installed on the back wall 2 of the greenhouse. The top of the straw curtain 14 is connected to the rolling shutter machine 15. After rolling, the bottom of the straw curtain 14 can extend to the bottom of the groove 7. One end of the box cover 62 can press and fix the bottom of the straw curtain 14 in the groove 7.

[0075] This invention realizes the secondary use and functional integration of the groove 7, which has two functions. First, it facilitates drainage and prevents rainwater from flowing away through the gap between the box cover 62 and the front wall 1, thus avoiding waste. Second, after the straw curtain 14 is rolled up in winter, the bottom end can be embedded in the slot and pressed by the box cover 62 to achieve good fixation of the straw curtain 14.

[0076] The end of the box cover 62 near the front wall 1 has several spaced rope holes 11, and a U-shaped rib 12 is also provided on the upper surface of the box cover 62; a pressure rope 13 is provided on the canopy 5, one end of the pressure rope 13 is connected to the steel bar hook on the rear wall 2, and the other end passes through the rope hole 11 and is connected to the U-shaped rib 12.

[0077] In some embodiments, the wall of the rope hole 11 can be reinforced with a stainless steel sleeve, and the ends of the sleeve are rounded. This design avoids breakage of the pressure rope 13 due to friction when it passes through. In this embodiment, the spacing between the rope holes 11 ensures uniform force distribution, forming a linear fixing band along the cover 62, which can disperse the tension of the greenhouse film under wind pressure.

[0078] The U-shaped ribs are made of Φ8mm round steel bent into shape and welded longitudinally along the 62 surface of the box cover.

[0079] In some embodiments, to address the problem that the tension of the traditional pressure-membrane rope 13 is not adjustable and is prone to loosening or becoming too tight due to seasonal changes, a modular rope tensioner is added to the surface of the box cover 62, as follows:

[0080] The box cover 62 is also equipped with a rope tensioner. The box cover 62 has several spaced threaded holes, and bolts 16 are threadedly connected in the threaded holes. The bottom of the bolts 16 is rotatably connected to the clips 17, which can be locked onto the pressure film rope 13.

[0081] The combination of rope hole 11, U-shaped rib, and rope tensioner can completely replace the ground anchor. This is achieved through the integrated design of the box cover 62, which reduces the installation process.

[0082] Based on Embodiment 1, this embodiment proposes a method for using an intensive rainwater harvesting system adapted to greenhouses, which also includes a straw curtain 14 fixing mode. The specific process is as follows:

[0083] B. The usage method of the straw mat 14 fixed mode is as follows:

[0084] In winter or during seasons with large temperature differences between day and night, the roof 5 needs to be covered with straw curtains 14 for insulation. The straw curtains 14 are rolled up using a rolling shutter machine 15, with the bottom end of the straw curtains 14 extending below the groove 7. The control box cover 62 is flipped so that one end of the box cover 62 presses down on the straw curtains 14 until the straw curtains 14 are positioned and fixed in the groove 7 by the box cover 62, thus completing the fixation of the bottom end of the straw curtains 14 and preventing the straw curtains 14 from being lifted up by strong winds.

[0085] When the membrane pressing rope 13 needs to be installed, the end of the membrane pressing rope 13 is passed through the rope hole 11 and tied to the U-shaped rib. Then, the bolt 16 is tightened, the clamp 17 is locked onto the membrane pressing rope 13, and the membrane pressing rope 13 is pressed down until the appropriate tension is achieved. The rope tensioner is equipped with a wrench, and the tension can be adjusted manually by rotating the bolt 16 to ensure that the straw curtain 14 is not affected under extreme weather conditions.

[0086] Application results:

[0087] When the diversion component 6 is used to fix the straw mat 14, the function of fixing the straw mat 14 is integrated into the existing rainwater harvesting system by designing rope holes 11, U-shaped ribs 12, membrane pressing ropes 13, and rope tensioners. This eliminates the need for separate construction and saves on the procurement, installation, and maintenance costs of traditional ground anchors. This "killing two birds with one stone" design achieves collaborative operation and functional integration. Functional integration reduces equipment redundancy in the greenhouse, enhances overall wind resistance, and solves the problem of single-function traditional systems.

It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.

8. A method for using an intensive rainwater harvesting system adapted for greenhouses, characterized in that, An intensive rainwater harvesting system adapted to greenhouses according to any one of claims 1-7 includes a rainwater harvesting mode and a straw curtain (14) fixing mode, the specific process of which is as follows: A. The rainwater harvesting mode is used as follows: When it is not raining, the lid (62) is fastened to the top of the box (61) to form a closed state, preventing garbage and impurities from entering the box (61); When it starts to rain, the lid (62) is kept closed for a time T. The initial rainwater flows down the edge of the roof (5) and is guided away through the flow channel (8). The initial rainwater cannot enter the box (61), thus achieving the diversion of the initial rainwater. After the rainwater is diverted, the control box cover (62) is flipped so that the box cover (62) is tilted. One end of the box cover (62) is connected to the front wall (1) to form a guide section. In the middle and later stages, the clean rainwater flows down the roof surface (5) and enters the box body (61) after being guided by the guide section. The clean rainwater flows into the water storage device (10) through the manifold (9) for storage. B. The method of using the fixed pattern of straw curtain (14) is as follows: In winter, the roof (5) needs to be covered with straw mats (14) for insulation. The straw mats (14) are rolled up using a rolling shutter machine (15), and the bottom of the straw mats (14) extends to the bottom of the groove (7). The control box cover (62) is flipped over so that one end of the box cover (62) presses down on the straw curtain (14) until the straw curtain (14) is positioned and fixed in the groove (7) by the box cover (62), thus completing the fixation of the bottom of the straw curtain (14) and preventing the straw curtain (14) from being lifted up by strong winds.
