Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouses, and in particular to a vegetable greenhouse with rainwater collection and irrigation regulation functions. Background Technology

[0002] A greenhouse is an outdoor framed, membrane-covered structure that effectively prevents the loss of carbon dioxide (produced by plant growth), thus providing excellent insulation and allowing people to enjoy out-of-season fruits and vegetables as well as plants.

[0003] With the widespread adoption of greenhouse cultivation technology, the techniques for growing vegetables and fruits in greenhouses have become increasingly sophisticated. However, a greenhouse is a relatively enclosed production facility that cannot effectively utilize natural rainfall. For example, during rainy weather, the plants are blocked from receiving rainwater by the greenhouse; rainwater falling on the greenhouse surface simply slides down into the surrounding soil, resulting in waste. Irrigation of the plants requires additional water, thus hindering the effective use of rainwater. When rainfall is excessive, too much rainwater flows into the surrounding soil, easily diluting it and affecting the stability of the greenhouse installation. In severe cases, it can even cause the greenhouse to collapse, resulting in economic losses. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vegetable greenhouse with rainwater collection and irrigation regulation functions. A deformable guide plate is installed on the top of the greenhouse frame. When it rains, the guide plate forms a U-shaped structure to collect rainwater and enter the greenhouse to complete irrigation. After the irrigation volume reaches the target, the guide plate forms an inverted U-shaped structure to guide the rainwater to the guide channels on both sides of the greenhouse, and then collects it in a water storage tank, which serves to store water and prevent excessive rainwater from flowing into the soil around the greenhouse.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vegetable greenhouse with rainwater collection and irrigation regulation function, including a greenhouse frame, a rainwater collection mechanism, irrigation pipelines, sprinkler heads, drain pipes, and an electrically controlled valve; the rainwater collection mechanism is provided above the greenhouse frame, and the rainwater collection mechanism consists of a water collection plate, a filter plate, a support rod, a rope retractor, a water guide plate, a lock, and ropes; the water collection plate is installed at the top center of the greenhouse frame, and the surface of the water collection plate has multiple drain outlets, at which filter plates are installed. The top surface of the water collection plate is equipped with at least two support rods, and rope retractors are installed on the left and right sides of the top of the support rods; the left and right sides of the water collection plate are hinged to the water guide plate, and the top surface of the water guide plate is equipped with a buckle, which is connected to the rope retractor on the same side by a rope; the greenhouse frame is equipped with an irrigation pipeline, and multiple sprinkler heads are installed below the irrigation pipeline; the irrigation pipeline is connected to the drain outlet of the water collection plate through a drain pipe, and the drain pipe is equipped with an electric control valve and a water flow sensor associated with the electric control valve.

[0006] The rope retractor consists of a waterproof cover, a motor, and a rope storage roller. The motor and the rope storage roller are installed inside the waterproof cover, and the output shaft of the motor is connected to the rope storage roller. The waterproof cover has an opening on the side facing the water guide plate on the same side. One end of the rope is connected to the rope storage roller, and the main body of the rope is wound around the rope storage roller. The other end of the rope is connected to a buckle on the water guide plate on the same side through the opening on the waterproof cover. When the output shaft of the motor rotates forward and backward, it can drive the rope storage roller to rotate forward and backward, thereby controlling the length of the rope extending from inside the waterproof cover and realizing the angle adjustment of the water guide plate. The motor is associated with a water flow sensor. When the water flow sensor detects that the amount of water passing through the drain pipe reaches a set value, the water flow sensor sends a signal to the motor, and the motor starts to extend the length of the rope extending from inside the waterproof cover. Under the action of gravity, the water guide plate flips downward at a certain angle to form an inverted U-shaped structure.

[0007] Water-blocking strips are provided on both the front and rear sides of the water collection plate and the water guide plate. When collecting rainwater, the water-blocking strips can prevent rainwater from flowing out from the front and rear sides of the water collection plate and the water guide plate.

[0008] The irrigation pipeline is located in the upper area inside the greenhouse frame. The irrigation pipeline has an inverted U-shaped structure, which is adapted to the raised structure at the top of the greenhouse frame.

[0009] The greenhouse frame is equipped with drainage channels on both the left and right sides, and a water storage tank is set on one side of the greenhouse frame. The drainage channels and the water storage tank are connected by a water pipe. Excess rainwater flows from the top of the greenhouse frame to the drainage channels, and then flows into the water storage tank through the water pipe.

[0010] The beneficial effects of this utility model are as follows: The vegetable greenhouse is equipped with a deformable guide plate at the top of the greenhouse frame. When it rains, the rope retractor shortens the rope, causing the guide plate to form a U-shaped structure to collect rainwater into the greenhouse for irrigation. When the water flow sensor detects that the water volume has reached the standard, it will close the electronic control valve. At this time, the rope retractor lengthens the rope, causing the guide plate to form an inverted U-shaped structure to guide the rainwater to the guide channels on both sides of the greenhouse frame, and then collect it in the water storage tank. This achieves intelligent irrigation, water storage, and prevents excessive rainwater from flowing into the soil around the greenhouse. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0017] Reference Figure 1-3 This embodiment provides a vegetable greenhouse with rainwater harvesting and irrigation regulation functions, including a greenhouse frame 1, a rainwater harvesting mechanism, an irrigation pipeline 2, a sprinkler head 3, a drain pipe 4, and an electrically controlled valve 5. The rainwater harvesting mechanism is located above the greenhouse frame 1 and consists of a water collection plate 6, a filter plate 7, a support rod 8, a rope retractor 9, a water guide plate 10, a locking buckle 11, and a rope 12. The water collection plate 6 is installed at the top center of the greenhouse frame 1, and its surface has multiple strip-shaped drain outlets. The filter plate 7 is installed at each drain outlet to prevent impurities from entering, and it can be removed from the water collection plate 6 for cleaning. Two support rods 8 are bolted to the top surface of the water collection plate 6, and rope retractors 9 are bolted to the top left and right sides of the support rods 8; the left and right sides of the water collection plate 6 are hinged to the water guide plate 10, and the top surface of the water guide plate 10 is bolted to the position corresponding to the rope retractor 9, and the lock 11 is connected to the rope retractor 9 on the same side through the rope 12; the greenhouse frame 1 is equipped with an irrigation pipeline, and multiple sprinkler heads 3 are provided below the irrigation pipeline; the irrigation pipeline 2 is connected to the drain of the water collection plate 6 through a drain pipe 4, and the drain pipe 4 is equipped with an electric control valve 5 and a water flow sensor associated with the electric control valve 5.

[0018] In this embodiment, the rope retractor 9 consists of a waterproof cover, a motor, and a rope storage roller. The motor and the rope storage roller are installed inside the waterproof cover. The output shaft of the motor is connected to the rope storage roller. The waterproof cover has an opening on the side facing the water guide plate 10 on the same side. The rope storage roller is connected to one end of the rope 12. The main body of the rope 12 is wound around the rope storage roller. The other end of the rope 12 is connected to the latch 11 on the water guide plate 10 on the same side through the opening of the waterproof cover. When the output shaft of the motor rotates forward and backward, it can drive the rope storage roller to rotate forward and backward, thereby controlling the extension length of the rope 12 from inside the waterproof cover and realizing the angle adjustment of the water guide plate 10. The motor is associated with a water flow sensor. When the water flow sensor detects that the amount of water passing through the drain pipe 4 reaches a set value, the water flow sensor sends a signal to the motor. The motor starts to extend the length of the rope 12 from inside the waterproof cover. Under the action of gravity, the water guide plate 10 flips downward at a certain angle to form an inverted U-shaped structure.

[0019] In this embodiment, water baffles 13 are provided on both the front and rear sides of the water collection plate 6 and the water guide plate 10. When collecting rainwater, the water baffles 13 can prevent rainwater from flowing out from the front and rear sides of the water collection plate 6 and the water guide plate 10.

[0020] In this embodiment, the irrigation pipe 2 is located in the upper area inside the greenhouse frame 1. The irrigation pipe 2 has an inverted U-shaped structure, which is adapted to the protruding structure at the top of the greenhouse frame 1.

[0021] In this embodiment, diversion channels 14 are installed on the left and right sides of the greenhouse frame 1, and a water storage tank 15 is set on one side of the greenhouse frame 1. The diversion channels 14 and the water storage tank 15 are connected by a water pipe 16. Excess rainwater flows from the top of the greenhouse frame 1 to the diversion channels 14, and then flows into the water storage tank 15 through the water pipe 16 for storage.

[0022] In this embodiment, an elastic strip is provided at the hinge of the water collection plate 6 and the water guide plate 10. The elastic strip is preferably a rubber strip or a silicone strip. The elastic strip has good elasticity and does not affect the hinge rotation of the water guide plate 10. When the water guide plate 10 is in a U-shape, the elastic strip can fill the gap between the water collection plate 6 and the water guide plate 10, ensuring that the rainwater on the water guide plate 10 flows to the water collection plate 6.

[0023] The working principle of this device is as follows: When it rains and the vegetables inside the greenhouse frame 1 need irrigation, the motor in the rope retractor is activated simultaneously, shortening the extension length of the rope 12 and raising the water guide plate 10 into a U-shape. At the same time, the electric control valve 5 on the drain pipe 4 is opened, allowing rainwater on the water guide plate 10 to flow downwards onto the water collection plate 6. After being filtered by the filter plate 7, the water enters the drain pipe 4 and is then sprayed out through the sprinkler head 3 at the bottom of the irrigation pipe 2 for irrigation. When the water flow sensor detects that the water volume in the drain pipe 4 has reached the set value, the electric control valve 5 closes. Simultaneously, the water flow sensor sends a signal to the motor, causing the motor to rotate in the opposite direction, extending the length of the rope 12 extending from the waterproof cover. Under the action of gravity, the water guide plate 10 flips downwards at a certain angle into an inverted U-shape. At this time, the water on the water guide plate 10 is guided to the top of the greenhouse frame 1, then flows into the water guide trough 14, and finally enters the water storage tank 15 through the water guide pipe 16 for storage. Since the electric control valve 5 is closed at this time, the water stored on the water collection plate 6 will not enter the irrigation pipe 2.

[0024] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
