Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and particularly relates to an intelligent and precise sprinkler irrigation device for greenhouses and its sprinkler irrigation method. Background Art

[0002] In the field of agricultural irrigation, especially in greenhouse cultivation, traditional irrigation methods often struggle to meet the requirements of precise irrigation, leading to waste of water resources and uneven plant growth. In recent years, with the development of automation and intelligent technologies, intelligent sprinkler irrigation devices have gradually become a research hotspot, aiming to achieve precise irrigation management of the plant growth environment through the integration of sensor technology, automatic control, and adjustable spraying devices.

[0003] In the prior art, there are already some intelligent sprinkler irrigation devices for greenhouse cultivation. For example, CN112655438A discloses an intelligent sprinkler irrigation device for greenhouse cultivation in agriculture. This device drives the sprinkler head to perform circular reciprocating sprinkler irrigation through a driving mechanism and a rotating mechanism, and at the same time intelligently adjusts the water pressure through a control mechanism to expand the sprinkler irrigation range and avoid damaging the planted crops. However, this system still has the following deficiencies: Limited sprinkling range: Although this system realizes the circular reciprocating sprinkler irrigation of the sprinkler head, its sprinkling range is still limited by the device structure and the size of the greenhouse, and it is difficult to flexibly adapt to greenhouses of different scales and shapes.

[0004] Lack of automatic monitoring and regulation: This system mainly relies on manual control for water pressure adjustment and sprinkling range adjustment, lacking the function of automatically monitoring environmental factors such as soil humidity and light, and it is difficult to achieve true intelligent irrigation.

[0005] Low system integration: The components of this device are relatively independent, and the system integration is low, resulting in complex operation and high maintenance costs.

[0006] On the other hand, Chinese Patent CN116171771A proposes a greenhouse intelligent irrigation system and algorithm. This system realizes precise irrigation, fertilization, and pesticide spraying of greenhouse plants by establishing a deep learning-based pest type recognition and disaster degree estimation model, combining the monitoring values of EC sensors and PH sensors to infer fertilizer types and dosages, and an irrigation water volume calculation model based on soil moisture content. However, this system also has the following limitations: High hardware cost: This system involves multiple high-precision sensors and complex algorithm models, resulting in high hardware costs and being difficult to popularize among ordinary farmers.

[0007] Complex algorithm model: Although the application of deep learning algorithms improves the accuracy of pest identification and disaster degree estimation, it also increases the complexity and computational amount of the system, and has high requirements for hardware performance.

[0008] Limited adaptability: This system is mainly applicable to the greenhouse environment and has limited adaptability to open-field farmland or other planting environments.

[0009] In view of the defects and deficiencies of the above-mentioned existing technical solutions, the present invention proposes an intelligent precise sprinkler irrigation device for greenhouses and its sprinkler irrigation method. This system not only inherits the advantages of the existing technology, such as circular reciprocating sprinkler irrigation and intelligent water pressure adjustment, but also realizes the comprehensive monitoring and precise irrigation management of the plant growth environment by integrating soil moisture sensors, automated control systems and adjustable sprinkler devices. At the same time, this system focuses on reducing costs, improving adaptability and ease of use to meet a wider range of agricultural irrigation needs. Summary of the Invention

Its shape is similar to the greenhouse frame, but more concise, so as to minimize the impact on the cultivated area. The frame main body is made of lightweight but strong materials, such as aluminum alloy or high-strength plastic, to ensure stability and durability.

[0043] Roof beam device 2: Installed above the frame body 1 and extending along the length direction of the greenhouse. There is a groove inside the roof beam device 2, and sliding grooves 8 are symmetrically arranged on both sides of the groove. The surface of the sliding groove 8 is smooth to ensure that the spraying device 3 can slide along it smoothly. The material of the roof beam device 2 is selected to match that of the frame body 1 to ensure the stability and consistency of the overall structure. A driving motor is provided on the roof beam device 2, which is connected to the spraying device 3 and the storage battery, and is used to drive the spraying device 3 to move along the sliding groove 8, so that the spraying device 3 can flexibly adjust its position to achieve precise spraying of different areas inside the house.

[0044] 2. Detailed structure of the spraying device 3 Mounting seat 10 and folding device 5: The spraying device 3 consists of a group of mounting seats 10, which are connected by the folding device 5. The folding device 5 is composed of multiple telescopic segments, and its expansion and contraction are controlled by the compression pump 14. The compression pump 14 is installed at one end of the folding device 5 and is controlled by the control system through wire connection. When the spraying height needs to be adjusted, the control system sends a signal to the compression pump 14 to drive it to work, thereby driving the folding device 5 to contract or extend.

[0045] Placement frame 6 and high-pressure water gun 7: One side of the mounting seat 10 is connected to the sliding groove 8 on the roof beam device 2 through the card seat 11, and the other side of the mounting seat 10 is connected to the placement frame 6. The placement frame 6 is U-shaped and is used to fix the high-pressure water gun 7. The gun body of the high-pressure water gun 7 is fixed on the placement frame 6 through the card hole 9 to ensure its stability. The high-pressure water gun 7 includes a water spraying port 12, a water inlet 13 and a gun body.

The drive motor is connected to the spraying device 3 through a transmission device such as a gear or a belt to ensure its smooth movement.

[0049] Spraying height adjustment: After reaching the specified position, the control system will control the compression pump 14 to contract or extend according to the height information of the position where the spraying device 3 is located (which can be obtained through sensors or preset data), so as to adjust the height of the spraying device 3 to a position suitable for sprinkler irrigation.

[0050] Spraying operation: After the height adjustment is completed, the control system will start the high-pressure water gun 7, and spray delicate water mist through the water spray port 12 to irrigate the plants. During the spraying process, the control system will continuously monitor the data of the soil humidity sensor 4. When the soil humidity reaches or exceeds the preset threshold, the spraying operation will be automatically stopped.
