Description

Technical Field

[0001] The present invention belongs to the technical field of rainwater collection, and in particular relates to an intensive rainwater collection system and method suitable for greenhouses. Background Art

[0002] As the core facility of facility agriculture, the functional design of greenhouses must take into account the environmental needs of different seasons: in the rainy season, clean rainwater must be efficiently collected to reduce irrigation costs, and in the winter, straw mats must be reliably fixed to ensure insulation.

[0003] While existing rainwater collection systems provide basic diversion capabilities, they lack a mechanism for discarding runoff. Initial rainwater carries pollutants such as dust, pesticide residues, and bird droppings accumulated on the shed surface. Direct collection can severely contaminate the water storage system and affect irrigation water quality.

[0004] Existing rainwater collection systems can only be used during the rainy season and are generally idle in the winter. Existing greenhouses require straw mats for insulation during winter or when there's a significant temperature swing between day and night. These mats typically rely on independent ground anchors to secure them, making installation time-consuming and labor-intensive, and prone to loosening. Consequently, existing rainwater collection systems and greenhouse insulation systems are independent of each other, lacking functional integration. This results in single-function equipment, wasted resources, and high installation and maintenance costs, which is inconsistent with the intensive development of greenhouses.

[0005] Therefore, it is necessary to make improvements to the above problems. Summary of the Invention

[0006] This invention aims to address, at least to some extent, one of the technical issues in the related art. To this end, it proposes an intensive rainwater collection system and method for greenhouses. This system utilizes the inclined surface of the greenhouse lid to divert rainwater during rainy seasons and uses the lid to hold and secure straw mats in place during winter, creating a multifunctional, integrated design. This not only improves rainwater collection efficiency and water quality, but also reduces greenhouse equipment redundancy through functional integration, enhancing overall wind resistance and providing technical support for the intensive upgrading of facility agriculture.

[0009] Preferably, it further 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 flip mechanism is arranged in the sandwich.

[0010] Preferably, the first support arm is fixedly connected to a first ear seat, the active arm is fixedly connected to a second ear seat, and both ends of the connecting rod are hinged to the first ear seat and the second ear seat respectively.

[0011] Preferably, the front wall is provided with a groove, and when the box cover is turned over, one end of the box cover can be inserted into the groove.

[0012] Preferably, the device further comprises a controller and a rain sensor, wherein the controller is electrically connected to the electric push rod and the rain sensor respectively.

[0013] Preferably, the shed surface is covered with straw curtains, a roller curtain machine is set on the back wall of the shed, the top of the straw curtain is connected to the roller curtain machine, and the bottom end of the straw curtain extends to the bottom of the groove; one end of the box cover can press and fix the bottom end of the straw curtain in the groove.

[0014] Preferably, a plurality of spaced rope holes are provided at the end of the box cover close to the front wall, and U-shaped ribs are provided on the upper surface of the box cover; a film pressing rope is provided on the roof surface, one end of the film pressing rope is connected to the steel hook on the rear wall, and the other end passes through the rope hole and is connected to the U-shaped rib.

[0015] Preferably, the box cover is further provided with a rope tightener, and the box cover is provided with a plurality of spaced threaded holes, in which bolts are threadedly connected, and the bottom of the bolt is rotatably connected to a clamp, and the clamp can be clamped on the film pressing rope.

[0016] On the other hand, the present invention also proposes a method for using an intensive rainwater collection system adapted for a greenhouse, including a rainwater collection mode and a straw curtain fixing mode. The specific process is as follows: A. How to use the rainwater collection mode is as follows: When it is not raining, the box cover is buckled on the top of the box to form a closed state, preventing garbage and impurities from entering the box; When it starts to rain, the box cover is kept closed for T time. The initial rainwater flows down along the edge of the roof and is drained away through the flow channel. The initial rainwater cannot enter the box, thus achieving the goal of discarding the initial rainwater. After the rainwater is abandoned, the box cover is controlled to flip and tilt, and one end of the box cover is connected to the front wall to form a diversion part. The clean rainwater in the middle and late stages flows down along the roof surface and enters the box body after being guided by the diversion part. The clean rainwater flows into the water storage device through the confluence pipe for storage. B. How to use the straw mat fixed mode is as follows: In winter, the shed surface needs to be covered with straw mats for insulation. The straw mats are rolled up using a rolling machine, and the bottom of the straw mats extends to the bottom of the groove. The box cover is controlled to flip so that one end of the box cover presses the straw curtain until the straw curtain is positioned and fixed in the groove by the box cover, thereby completing the fixation of the bottom end of the straw curtain to prevent the straw curtain from being lifted up in strong winds.

[0017] The above technical solution has the following advantages: 1. The present invention uses a designed flow-discarding component. In the initial stage of rain, the box cover remains closed, and rainwater flows along the edge of the shed into the flow channel between the front wall and the box body, and is directly discharged to the outside of the shed, preventing polluted water from entering the collection system. After the initial rainwater is drained, the box cover flips and tilts to guide the middle and late clean rainwater to flow into the box body, thereby realizing the collection of clean rainwater.

[0018] 2. The flow-discarding component in the present invention has two states. When the box cover is tilted, a "diversion slope" is formed, allowing rainwater on the roof to flow quickly into the box along the slope, reducing splashing and loss. When it is not raining, the box cover is closed and seals the box to prevent leaves, dust and other debris from entering, keeping the interior clean and providing favorable conditions for collecting clean rainwater.

[0019] 3. The present invention presets a groove on the front wall of the greenhouse, and the rear end of the box cover is flipped and inserted into the groove. Firstly, it is conducive to diversion and prevents rainwater from flowing away through the gap between the box cover and the front wall, causing waste; secondly, the bottom end of the straw curtain can be embedded in the card slot after being rolled up in winter, and cooperated with the box cover to press and hold, so that the straw curtain can be well fixed.

[0020] 4. When the flow-discarding assembly is used to secure straw mats, the present invention integrates the straw mat securing function into the existing rainwater collection system through the design of rope holes, U-shaped ribs, film-pressing ropes, and rope tensioners. This eliminates the need for separate construction and reduces the procurement, installation, and maintenance costs of traditional ground anchors. This "killing two birds with one stone" design achieves collaborative operation and functional integration. This functional integration reduces greenhouse equipment redundancy, enhances overall wind resistance, and addresses the single-function issue of traditional systems.

[0038] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0039] Example 1: like Figure 1 - Figure 9 As shown, this embodiment proposes an intensive rainwater collection system suitable for 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; a frame 4 is provided on the top of the greenhouse body, and a roof surface 5 is covered on the frame 4, and the top frame 4 and the roof surface 5 constitute a "roof".

[0040] At least one set of flow-discarding assemblies 6 is also provided on the front side of the front wall 1. These flow-discarding assemblies 6 are fixed to the ground using anchor bolts 16 or expansion bolts 16. In this embodiment, multiple sets of flow-discarding assemblies 6 are arranged in a row, with adjacent flow-discarding assemblies 6 connected in series via connecting pipes. The flow-discarding assemblies 6 include a box 61 with an opening. The box 61 can be rectangular in structure, with a gap between the box 61 and the front wall 1, forming a flow passage 8. Before installing the flow-discarding assemblies 6, the ground in front of the front wall 1 needs to be hardened to facilitate the installation and fixation of the box 61 and the flow of water within the flow passage 8.

[0041] The top of the box body 61 is equipped with a reversible lid 62 that snaps onto the top of the box body 61, creating a closed state. When the lid 62 is flipped, it tilts, with one end connected to the front wall 1 and the other end projecting into the opening at the top of the box body 61, forming a diversion portion for guiding rainwater flowing from the roof 5 into the box body 61. In other words, after the lid 62 is flipped and tilted, it must ensure that rainwater flows smoothly along the lid 62 into the box body 61. The box body 61 is connected to one end of a manifold 9, the other end of which 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.

[0042] In this embodiment, the front wall 1 is a low wall of the greenhouse close to the sunny side, usually made of bricks, concrete or earth walls, which not only plays a basic supporting role, but also reduces the direct intrusion of cold air from the ground into the greenhouse. The back wall 2 is the main wall of the shady side of the greenhouse. The inside of the wall may be filled with insulation cotton, polystyrene board and other materials, and the outside is plastered with cement or insulation board to reduce heat loss at night. A beam or steel pipe will be installed on the top of the back wall 2 to fix the roller shutter 14 straw curtain; 15, straw curtain reel and other equipment. The wall may also reserve steel hooks for convenient connection of the film pressing rope 13. The side walls 3 connect the front wall 1 and the back wall 2 to form the two side facades of the greenhouse, and the height transitions with the front and back walls 2. The top frame 4 is the "backbone" that supports the roof 5. It is usually built with hot-dip galvanized steel pipes, aluminum alloy profiles or bamboo poles, and is designed into different shapes according to the type of greenhouse. The shed surface 5 covered on the frame 4 is the "outer coat" of the greenhouse, which is mainly made of aging-resistant plastic film, glass or sunlight board, which can ensure light transmission and prevent wind and rain.

[0043] The specific structure for realizing the flipping between the box cover 62 and the box body 61 is as follows: A flipping mechanism is provided between the box cover 62 and the box body 61, and 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 box cover 62, and the other end is hinged to the side wall of the box body 61; one end of the second arm 64 is hinged to the side wall of the box cover 62; it also includes an active arm 65, the active arm 65 is hinged to the box body 61, and the hinge point is set near the middle position of the active arm 65, forming a "lever-type" fulcrum structure; the other end of the second arm 64 is hinged to one end of the active arm 65; the side wall of the box body 61 is also hinged with an electric push rod 69, and 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 the connecting rod 68 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 synchronously pull the first arm 63 to swing when the active arm 65 rotates, ensuring the coordinated movements of the first arm 63 and the second arm 64, and preventing the box cover 62 from getting stuck due to uneven force.

[0044] In this embodiment, the length of the second arm 64 is greater than the length of the first arm 63 to ensure that the box cover 62 can form an inclined state after being turned over.

[0045] Working principle of the flip mechanism: Initial state: The lid 62 is snapped onto the top of the case 61, the push rod 69 is retracted, the active arm 65 is in a horizontal position, and the first and second arms 63, 64 are folded into a stowed position. To initiate the flip, the push rod 69 is energized and extends, pushing the active arm 65 to rotate counterclockwise around its central pivot point. Because the second arm 64 is longer, the end of the lid 62 to which it is connected is lifted faster and to a greater extent, while the first arm 63, being shorter, is lifted less. This length difference between the two arms creates a differential lift, causing the lid 62 to naturally tilt toward the case 61. Simultaneously, the active arm 65 drives the first arm 63 to swing synchronously via the connecting rod 68, ensuring a smooth and seamless tilting process.

[0046] The case 610 also includes a protective shell 610 connected to the side walls of the case 61. A sandwich is formed between the protective shell 610 and the side walls of the case 61. The top of the sandwich is open, and the flip mechanism is located within the sandwich. The protective shell 610 is formed by bending hot-dip galvanized steel sheet and rigidly connected to the side walls of the case 61 by welding or bolting. The resulting sandwich completely encloses the flip mechanism, including the first arm 63, second arm 64, active arm 65, and connecting rod 68. This prevents the case cover 62 from flipping, while also providing a physical barrier and extending the life of the flip mechanism.

[0047] In this embodiment, the first support 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 both ends of the connecting rod 68 are hinged to the first ear seat 66 and the second ear seat 67 respectively.

[0048] Considering that after the box cover 62 is flipped over, there is a gap between the edge of the box cover 62 and the front wall 1, which is not conducive to rainwater collection, a groove 7 is formed in the front wall 1. When the box cover 62 is flipped over, one end of the box cover 62 can be inserted into the groove 7. The design of the groove 7 allows one end of the box cover 62 to be inserted into the groove 7, filling the gap and facilitating the collection of rainwater.

[0049] In order to achieve intelligent control, the entire system also includes a controller and a rain sensor. The controller is electrically connected to the electric push rod 69 and the rain sensor respectively. The rain sensor is installed on the greenhouse body or the box 61. The controller can receive signals from the rain sensor and control the movement of the electric push rod 69.

[0050] The system is further provided with a relay, and the controller is control-connected to the relay.

[0051] This embodiment also proposes a method for using an intensive rainwater collection system adapted for a greenhouse, including a rainwater collection mode. The specific process is as follows: A. How to use the rainwater collection mode is as follows: When it is not raining, the box cover 62 is buckled on the top of the box body 61, forming a closed state to prevent garbage and impurities from entering the box body 61; specifically, the rain sensor detects a no rain signal, the controller cuts off the power supply of the electric push rod 69 through the relay, and the box cover 62 is buckled on the top of the box body 61 under the action of gravity and the tension of the first arm 63 and the second arm 64.

[0052] When it starts to rain, the box cover 62 is kept closed for a period of time T. The initial rainwater flows down along the edge of the roof surface 5 and is drained away through the flow channel 8. The initial rainwater cannot enter the box body 61, thus achieving the goal of discarding the initial rainwater. Specifically, when the rain sensor detects rainfall, the controller starts the timer while simultaneously de-energizing the relay and keeping the box lid 62 closed. Initial rainwater, carrying pollutants from the roof surface 5, naturally drains along the edge of the roof surface 5 through the flow channel 8 between the front wall 1 and the box body 61 to the drainage ditch outside the greenhouse, achieving physical isolation. The flow abandonment time T can be adaptively adjusted by the controller. In this embodiment, the default setting is 10-15 minutes, but users can adjust it based on local conditions.

[0053] After the rainwater is abandoned, the control box cover 62 is flipped to make the box cover 62 inclined, and one end of the box cover 62 is connected to the front wall 1 to form a diversion part; in the middle and late stages, the clean rainwater flows down along the roof surface 5, and enters the box body 61 after being guided by the diversion part. The clean rainwater flows into the water storage device 10 through the confluence pipe 9 for storage.

[0054] Specifically, after the timer reaches T, the controller outputs a signal via the relay, energizing and extending the electric push rod 69, which activates the tilting mechanism to tilt the lid 62. At this point, one end of the lid 62 inserts into the groove 7 of the front wall 1, forming a diversion slope that connects to the roof surface 5. In the middle and later stages, rainwater flows from the roof surface 5 to the lid 62, then to the opening of the housing 61, flowing through the manifold 9 to the water storage device 10. It should be noted that a stainless steel filter can be installed at the inlet of the manifold 9 to filter out any remaining fine impurities. The controller receives real-time signals from the rain sensor. If rainfall ceases, it controls the electric push rod 69 to reverse after a 10-minute delay, causing the lid 62 to reclose.

[0055] Application results: The present invention has a designed flow-discarding component 6. In the initial stage of rain, the box cover 62 remains closed, and rainwater flows along the edge of the shed 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 shed, thereby preventing polluted water from entering the collection system. After the initial rainwater is drained, the box cover 62 flips and tilts to guide the clean rainwater in the middle and late stages to flow into the box body 61, thereby realizing the collection of clean rainwater.

[0056] Example 2: like Figure 10-15 As shown, on the basis of Example 1, the shed surface 5 is covered with straw curtains, and a curtain roller 14; 15 is set on the rear wall 2 of the shed. The top of the straw curtain is connected to the curtain roller 14; 15. After unrolling, the bottom end of the straw curtain can extend to the bottom of the groove 7; one end of the box cover 62 can press and fix the bottom end of the straw curtain in the groove 7.

[0057] The present invention realizes the secondary utilization and functional combination of the groove 7, which has two functions. First, it is conducive to diversion and prevents rainwater from flowing away through the gap between the box cover 62 and the front wall 1, causing waste; second, in winter, after the straw curtain is rolled up, the bottom end can be embedded in the card slot, and cooperated with the box cover 62 to press and hold, so that the straw curtain can be well fixed.

[0058] A plurality of spaced rope holes 11 are provided at the end of the box cover 62 close to the front wall 1, and a U-shaped rib 12 is also provided on the upper surface of the box cover 62; a film pressing rope 13 is provided on the roof surface 5, one end of the film pressing 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.

[0059] In some embodiments, the walls of the rope threading holes 11 can be reinforced with stainless steel sleeves, with rounded ends. This design prevents breakage of the film pressing rope 13 due to friction when passing through. In this embodiment, the spacing of the rope threading holes 11 ensures uniform force distribution, forming a linear fixing band along the cover 62, which disperses the tension on the greenhouse film under wind pressure.

[0060] The U-shaped ribs are formed by bending Φ8mm round steel and welded longitudinally along the surface of the box cover 62.

[0061] In some embodiments, to solve the problem that the tension of the conventional film pressing rope 13 cannot be adjusted and is easily loosened or over-tightened due to seasonal changes, a modular rope tightener is added to the surface of the box cover 62, as follows: The box cover 62 is also provided with a rope tightener. The box cover 62 is provided with a plurality of spaced threaded holes. Bolts 16 are threadedly connected in the threaded holes. The bottom of the bolt 16 is rotatably connected to a clamp 17. The clamp 17 can be clamped on the film pressing rope 13.

[0062] The combination of the rope threading hole 11 + U-shaped reinforcement + rope tightener can completely replace the ground anchor, which is achieved through the integrated design of the box cover 62 and can reduce the installation process.

[0063] Based on the first embodiment, this embodiment proposes a method for using an intensive rainwater collection system adapted for a greenhouse, which also includes a straw curtain fixing mode. The specific process is as follows: B. How to use the straw mat fixed mode is as follows: In winter or seasons with large temperature differences between day and night, the roof 5 needs to be covered with straw mats for insulation. The straw mats are rolled up by the rolling curtain machine 14; 15, the bottom end of the straw mat is extended to the bottom of the groove 7; the box cover 62 is controlled to flip so that one end of the box cover 62 presses the straw mat until the straw mat is positioned and fixed in the groove 7 by the box cover 62, completing the fixation of the bottom end of the straw mat to prevent the straw mat from being lifted up in strong winds.

[0064] To install the film pressing rope 13, thread the end of the rope through the rope hole 11 and tie it to the U-shaped rib. Then, tighten the bolt 16, engage the clamp 17, and tighten the rope 13 until the desired tension is achieved. The rope tightener is equipped with a wrench, allowing manual adjustment of the bolt 16 to ensure the mat remains secure even in extreme weather conditions.

[0065] Application results: When the flow-discarding assembly 6 is used to secure the straw mat, the design of the rope holes 11, U-shaped ribs 12, film-pressing ropes 13, and rope tensioners integrates the straw mat securing function into the existing rainwater collection system, eliminating the need for separate construction and reducing the procurement, installation, and maintenance costs of traditional ground anchors. This "killing two birds with one stone" design achieves collaborative operation and functional integration. This functional integration reduces greenhouse equipment redundancy, enhances overall wind resistance, and addresses the single-function issue of traditional systems.

[0066] It should be noted that many of the components mentioned in the present invention are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0067] The principles and implementation methods of the present invention are described herein using specific examples. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.

A method for using an intensive rainwater collection system adapted for a greenhouse, characterized in that: An intensive rainwater collection system adapted to a greenhouse according to any one of claims 1 to 9 includes a rainwater collection mode and a straw curtain fixing mode, and the specific process is as follows: A. How to use the rainwater collection mode is as follows: When it is not raining, the box cover (62) is buckled on the top of the box body (61), forming a closed state to prevent garbage and impurities from entering the box body (61); When it starts to rain, the box cover (62) is kept in the closed state for a period of time T, and the initial rainwater flows down along the edge of the roof surface (5) and is drained away through the flow channel (8). The initial rainwater cannot enter the box body (61), thereby achieving the purpose of discarding the initial rainwater. After the rainwater is abandoned, the control box cover (62) is turned over so that the box cover (62) is tilted, and one end of the box cover (62) is connected to the front wall (1) to form a diversion part; the clean rainwater in the middle and late stages flows down along the roof surface (5) and enters the box body (61) after being guided by the diversion part, and the clean rainwater flows into the water storage device (10) through the confluence pipe (9) for storage. B. How to use the straw mat fixed mode is as follows: In winter, the roof (5) needs to be covered with straw mats for insulation. The straw mats are rolled up using a rolling machine (14 straw mats; 15), and the bottom end of the straw mats extends to the bottom of the groove (7); The control box cover (62) is turned over so that one end of the box cover (62) presses the straw curtain until the straw curtain is positioned and fixed in the groove (7) by the box cover (62), thereby completing the fixing of the bottom end of the straw curtain and preventing the straw curtain from being lifted up in strong winds.
