Description

Technical Field

[0001] This invention relates to the field of greenhouse irrigation technology, specifically to a smart sprinkler irrigation system for vegetable greenhouses. Background Technology

[0002] A vegetable greenhouse is a frame-and-film structure with excellent heat insulation properties, enabling people to eat out-of-season vegetables. Generally, vegetable greenhouses use a bamboo or steel frame covered with one or more layers of insulating plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growing vegetables inside, ensuring good heat retention within the greenhouse.

[0003] The construction process for vegetable greenhouses is relatively simple, but the technology is quite sophisticated. my country's vegetable supply mainly relies on greenhouse cultivation; therefore, the construction quality and design structure of vegetable greenhouses directly affect the yield and quality of vegetables in my country.

[0004] Structurally, a vegetable greenhouse mainly consists of load-bearing walls, a structural steel frame, supporting columns, an arched roof, and a plastic outer film. In terms of supporting facilities, a modern greenhouse typically includes planting troughs, a sprinkler irrigation system, a temperature control system, an auxiliary lighting system, and a humidity control system. Planting troughs are located at the bottom of windows or are made into partitions for growing vegetables; the sprinkler irrigation system automatically supplies water in a timely and appropriate manner; the temperature control system includes exhaust fans, hot air fans, temperature sensors, and a constant temperature system control box to adjust the temperature as needed; the auxiliary lighting system includes plant lights and reflectors, installed around the planting troughs to provide illumination when there is no sunlight, enabling the plants to photosynthesize; the humidity control system works in conjunction with the exhaust fans to regulate humidity and lower the indoor temperature.

[0005] Specifically, the irrigation of greenhouse vegetables aims to ensure that the vegetables receive adequate and sufficient water throughout their different growth stages through proper watering, thereby promoting robust growth and increasing crop yield. Therefore, the rationality of the sprinkler irrigation system design directly affects the final yield and quality of the vegetable crops.

[0006] Existing vegetable greenhouses mostly use traditional manual sprinkler irrigation. Due to its inherent limitations, this method often presents numerous problems when applied on a large scale, including:

[0007] 1. The sprinkler irrigation method is limited, and the parameters during the sprinkler irrigation process are not easy to adjust, making it difficult to achieve adaptive sprinkler irrigation for different types of vegetables at different growth stages.

[0008] 2. Sprinkler irrigation has a low degree of automation. Controlling the amount of water required for sprinkler irrigation requires a lot of manual intervention. Furthermore, due to the limitations of water pipe laying, it can often only achieve fixed-point sprinkler irrigation and cannot cover all vegetables. This makes it very easy to leave sprinkler dead zones in the overall sprinkler irrigation process, affecting the sprinkler irrigation effect.

[0009] 3. During irrigation, the long delivery distance can easily lead to untimely replenishment of irrigation water, resulting in uneven sprinkler irrigation.

[0010] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0011] To address the shortcomings of existing technologies, this invention provides a smart sprinkler irrigation system for vegetable greenhouses. This system solves the problems of traditional sprinkler irrigation methods in modern greenhouse vegetable cultivation, such as limited irrigation methods, poor irrigation performance, low automation, difficulty in achieving comprehensive coverage of all vegetables inside the greenhouse, and inconvenience in long-distance water supply.

[0012] To achieve the above objectives, the present invention provides the following technical solution:

[0013] A smart sprinkler irrigation system for vegetable greenhouses includes a greenhouse body, which includes a greenhouse foundation. A circumferential greenhouse wall is fixed to the greenhouse foundation. An arched steel frame is fixed to the upper end of the greenhouse wall. An outer greenhouse film is covered on the arched steel frame. A smart sprinkler irrigation system is installed inside and outside the greenhouse body. The smart sprinkler irrigation system includes a water collection and supply component and an adjustable sprinkler component.

[0014] As an optimized solution, the adjustable sprinkler assembly includes two laterally extending limiting slide rails, which are U-shaped guide rails with side openings. The limiting slide rails are fixed on the longitudinal inner wall of the greenhouse wall near the upper end, and each limiting slide rail is fitted with a sliding bracket.

[0015] As an optimized solution, two symmetrical support guide beams are fixed between the two longitudinally opposite sliding seats. A fixed end cover is provided between the two support guide beams. The fixed end cover is a U-shaped cover with the opening facing downwards. A square horizontal support plate is fixed to the lower end of the fixed end cover. Two symmetrical dual-output shaft motors are fixed to the upper surface of the fixed end cover along the longitudinal direction. A drive roller is fixed to the end of each output shaft of the dual-output shaft motor. The drive roller rotates against the upper surface of the support guide beam.

[0016] As an optimized solution, a steering drive motor is fixedly connected to the center of the upper surface of the horizontal support plate, and the end of the output shaft of the steering drive motor passes downward through the horizontal support plate and is fixedly connected to a square steering seat.

[0017] As an optimized solution, a square follow-up water tank is fixedly connected to the inner top surface of the square steering seat, and a diversion box is provided below the follow-up water tank. The follow-up water tank and the diversion box are connected by a corrugated pipe.

[0018] As an optimized solution, two symmetrical lifting and telescopic cylinders are also fixedly connected to the lower surface of the square steering seat. The two lifting and telescopic cylinders are arranged laterally on both sides of the follow-up water storage tank, and each lifting and telescopic cylinder has a clamping side plate fixedly connected to its lower telescopic end.

[0019] As an optimized solution, a fixed irrigation pipe and a rotating irrigation pipe are respectively connected to the two lateral side end faces of the diversion box. The fixed irrigation pipe is a laterally extending rectangular tube, and the rotating irrigation pipe is a laterally extending round tube. The fixed irrigation pipe passes through and is fixedly clamped to one of the clamping side plates, and the rotating irrigation pipe passes through and is rotatably clamped to the other clamping side plate.

[0020] As an optimized solution, a number of fixed three-nozzle heads are fixedly connected to the outer peripheral wall of the rotating irrigation pipe along the axial direction, and the lower surface of the fixed irrigation pipe is provided with a rotating three-nozzle head corresponding to each of the rotating motors.

[0021] As an optimized solution, the water collection and supply assembly includes two symmetrically arranged rainwater collection boxes. The rainwater collection boxes are fixed to the upper part of the longitudinal outer wall of the greenhouse enclosure. The rainwater collection boxes are rectangular boxes with an opening at the top. A horizontal isolation screen is fixed to the opening at the top of the rainwater collection box. Two symmetrical arc-shaped buffer baffles are respectively provided on both sides above the arched steel frame. The lower end of the arc-shaped buffer baffles is fixed to the upper end of the rainwater collection box.

[0022] As an optimized solution, two symmetrical water pumps are fixedly connected to each rainwater collection box on the foundation of the greenhouse. The water pumps are located on the outside of the greenhouse wall. Each water pump is connected to a vertical water inlet pipe. Two symmetrical drain pipes are connected to the lower end face of each rainwater collection box. The drain pipes are arranged opposite to the water inlet pipes. A three-way valve is fixed between the drain pipes and the water inlet pipes. The longitudinal port of the three-way valve is connected to a horizontal transfer water pipe.

[0023] As an optimized solution, the transfer water pipe passes through the side wall of the greenhouse enclosure and extends into its interior. A supplementary water supply pump is fixedly connected to the longitudinal inner side wall of the greenhouse enclosure. The end of the transfer water pipe is fixedly connected to the inlet of the supplementary water supply pump, and a horizontal water supply pipe is fixedly connected to the outlet of the supplementary water supply pump.

[0024] As an optimized solution, a sliding drive motor is fixedly connected to each of the limiting slide rails on the transverse outer wall of the greenhouse enclosure. The output shaft of the sliding drive motor passes through the greenhouse enclosure and extends into the limiting slide rail. A horizontal threaded drive rod is fixedly connected to the end of the output shaft of the sliding drive motor. The end of the threaded drive rod is rotatably supported on the transverse inner wall of the other side of the greenhouse enclosure. The threaded drive rod passes through and is threadedly connected to the sliding bracket.

[0025] As an optimized solution, each longitudinal outer end face of the follow-up water tank is fixed with a horizontal water inlet pipe, and the water inlet pipe is equipped with a water inlet check valve. The water inlet pipe and the water supply pipe are at the same horizontal level. By connecting the water inlet pipe and the water supply pipe, the water for sprinkler irrigation can be injected into the follow-up water storage tank from the rainwater collection tank or the delivery water pump via the supplementary water supply pump.

[0026] As an optimized solution, a drive motor is provided above the rotating irrigation pipe. The drive motor is fixed to the transverse inner wall of the mounting side plate. The output shaft end of the drive motor passes through the mounting side plate and is fixed to a drive wheel. A drive retaining ring is fixed to the outer peripheral wall of the rotating irrigation pipe. The drive retaining ring abuts against the drive wheel for transmission.

[0027] As an optimized solution, several equally spaced rotating motors are fixedly connected to the upper surface of the fixed irrigation pipe along the transverse direction. The upper end of the rotating three-nozzle head is rotatably clamped inside the fixed irrigation pipe, and the output shaft end of the rotating motor passes downward through the fixed irrigation pipe and is fixed to the inner bottom surface of the rotating three-nozzle head.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] The water collection and supply component in this invention can, on the one hand, recycle rainwater and convert it into irrigation water, and on the other hand, periodically replenish the irrigation water during the movement of the adjustable sprinkler assembly, thereby ensuring the uniformity of irrigation. Specifically, the water collection and supply component includes two symmetrically arranged rainwater collection tanks. The rainwater collection tanks collect and store rainwater, which is then transferred to the supplementary water supply pump via a drain pipe, a three-way valve, and a transfer pipe. Furthermore, when the rainwater stored in the rainwater collection tanks is insufficient, an irrigation water pump can be used to transfer irrigation water to the supplementary water supply pump via a water inlet pipe, a three-way valve, and a transfer pipe. The irrigation water is then transferred to a follow-up water storage tank by starting and stopping the supplementary water supply pump for subsequent sprinkler irrigation.

[0030] The adjustable sprinkler assembly of this invention allows for movement and adjustment in both the horizontal and vertical directions. The sprinkler position can be changed by superimposing these two movements, ensuring complete coverage of the entire greenhouse and eliminating blind spots to improve overall irrigation efficiency. Furthermore, the adjustable sprinkler assembly incorporates both axial rotational irrigation and circumferential rotational irrigation methods. This diverse combination allows for adaptable irrigation for different types of vegetables. Specifically, the adjustable sprinkler assembly includes a diversion box, with rotating and fixed irrigation pipes respectively mounted on its side end. The system comprises a rotating irrigation pipe mounted on a distribution box. Driven by a transmission motor, the rotating irrigation pipe can rotate around its axis and achieve axial rotational irrigation via three fixed nozzles. The fixed irrigation pipe is directly fixed to the distribution box and is equipped with several rotating nozzles and corresponding motors. Driven by these motors, the rotating nozzles can achieve circumferential irrigation. Furthermore, the adjustable irrigation assembly can adjust various parameters such as the irrigation angle and height by starting and stopping the steering drive motor and controlling the extension and retraction of the lifting and telescopic cylinders, adapting to the irrigation needs of vegetables at different growth stages.

The water inlet pipe 28 and the water supply pipe 13 are at the same horizontal level. The water inlet pipe 28 is connected to the water supply pipe 13, so that the water for sprinkler irrigation can be injected into the follow-up water storage tank 25 from the rainwater collection tank 4 or the water delivery pump 7 via the supplementary water supply pump 12.

[0056] In use, this invention works as follows: First, rainwater is collected and reused using a rainwater collection tank 4, and debris is separated by an isolation screen 5. Rainwater slides down the outer membrane of the greenhouse and is stopped by an arc-shaped buffer baffle 6. When the rainwater collection tank 4 has sufficient water, the three-way valve 10 is opened, and rainwater flows from the rainwater collection tank 4 through the drain pipe 9 into the transfer water pipe 11, which then supplies the supplementary water supply pump 12. When the rainwater collection tank 4 is insufficient, the delivery water pump 7 is started, which lifts irrigation water along the water inlet pipe 8 to the transfer water pipe 11. Similarly, the supplementary water supply pump 12 is activated. In the initial state, the water supply pipe 13 and the inlet pipe 28 are connected. At the same time, the supplementary water supply pump 12 and the inlet check valve 29 are opened to inject irrigation water into the follow-up water storage tank 25. The water in the follow-up water storage tank 25 then enters the diversion box 26 through the corrugated pipe 27, and then is diverted to the fixed sprinkler pipe 32 and the rotating sprinkler pipe 33. At the same time, the two sliding drive motors 15 are started. The sliding drive motors 15 drive the threaded drive rod 16 to rotate, thereby driving the sliding bracket 17 to press against the limit rail. 14. Lateral sliding: Two dual-axis motors 21 are started respectively, which drive four drive rollers 22 to rotate, thereby driving the fixed end cover 19, horizontal support plate 20 and square steering seat 24 to slide longitudinally along two support guide beams 18. Through the superposition of lateral and longitudinal movements, the sprinkler can cover all areas inside the greenhouse; The transmission drive motor 34 is started, which drives the transmission wheel 35 to rotate. Through the transmission action of the transmission retainer 36, the rotating sprinkler pipe 33 is driven to rotate around the axis, and the fixed three sprinkler heads 37 are opened to realize rotating sprinkler irrigation; The rotating motor 38 is started, which drives the rotating three sprinkler heads 39 to rotate to realize circumferential sprinkler irrigation; The steering drive motor 23 is started, which drives the square steering seat 24 to rotate, which can realize the switching between rotating sprinkler irrigation and circumferential sprinkler irrigation, and increase the sprinkler range by steering; Furthermore, by controlling the lifting and telescopic, the diversion box 26, the fixed sprinkler pipe 32 and the rotating sprinkler pipe 33 can be raised and lowered to adjust the sprinkler height.
