Description

Technical Field

[0001] The present invention relates to irrigation facilities, and particularly to an irrigation facility for large-scale planting of tropical fruit trees in the field of irrigation equipment. Background Art

[0002] Tropical fruits are fruits that grow in tropical regions. They have a sweet taste and high nutritional value, and are an important type of cash crop. Therefore, they have high planting value. Tropical fruit trees like high-temperature and humid environments during their growth process. Also, due to the high-temperature environment, the water evaporation rate is fast, and irrigation work needs to be carried out regularly and frequently.

[0003] The specification of invention patent CN202411712152.4 discloses a drought-resistant and water-saving drip irrigation system for pitaya in tropical regions. Through a rainwater collection and filtration mechanism, a rainwater sterilization mechanism, a drip irrigation mechanism, and a soil humidity detection mechanism, the collection and utilization of rainwater are realized, as well as the precise irrigation of pitaya, improving the water resource utilization efficiency, so as to ensure the stable growth of pitaya in tropical regions and obtain good yields and qualities. The specification of invention patent CN202310088517.X discloses a drip irrigation water-saving device for planting fruit tree seedlings. When the drip irrigation control mechanism moves directly above the drip irrigation water-saving mechanism along the direction of the slideway, the drip irrigation state of the drip holes below the drip irrigation water-saving mechanism at this place can be observed. If the drip irrigation state is poor, the drip irrigation of the drip holes here can be improved by increasing the water passing area of the drip holes. The drip irrigation operation is convenient, fast, and targeted, effectively achieving the purpose of water-saving in drip irrigation operations.

[0004] Existing irrigation systems for planting tropical fruits are usually used for the planting of single fruit trees or fruit tree seedlings. The irrigation requirements of these fruit trees and fruit tree seedlings are roughly the same, so there is no need for differential irrigation. However, in the actual planting process, different varieties of fruit trees may be mixed in the fruit tree planting process, or the growth periods and maturity periods of the same type of fruit trees do not coincide, which leads to different irrigation requirements for the fruit trees, and a single irrigation line is difficult to meet the planting requirements of the fruit trees. Summary of the Invention

[0005] Aiming at the above-mentioned existing technologies, the technical problem to be solved by the present invention is that there are different irrigation requirements for multiple fruit trees during the planting process, and a single irrigation line is difficult to meet the planting requirements of the fruit trees.

[0006] To solve the above problems, the present invention provides an irrigation facility for large-scale planting of tropical fruit trees, including a control terminal. The control terminal is signal-connected to an implementation layer and a detection layer. The implementation layer includes a canopy micro-spray module and a root zone drip irrigation module. The detection layer includes a light sensor, a humidity sensor, and a temperature sensor;

[0007] The root zone drip irrigation module includes a water pump, a transition water tank, a connecting tee, and a drip irrigation module. The water pump is connected to the transition water tank, and the transition water tank is connected to the drip irrigation module through a transmission water pipe. Adjacent connecting tees are connected to each other through a transmission water pipe. The drip irrigation module includes a connecting part that matches the connecting tee. The connecting part is threadedly connected to the connecting tee. A communication port is drilled on the lower side wall of the connecting part. A sealing plug that matches itself is slidably connected inside the connecting part. A compression spring is fixedly connected between the sealing plug and the bottom plate of the connecting part. The elastic coefficients of the compression springs in multiple drip irrigation modules are not completely the same. When the compression spring is in its original length state, the position of the sealing plug matches the communication port. A limiting platform is fixedly connected to the bottom plate of the connecting part. An outer protection pipe is fixedly sleeved on the outside of the connecting part. Multiple drip irrigation ports are drilled on the side wall of the outer protection pipe close to the communication port.

[0008] In the above irrigation facility for large-scale planting of tropical fruit trees, it is realized to irrigate fruit trees with different irrigation requirements by using one drip irrigation water transmission pipeline, reducing the irrigation cost.

[0009] As a further improvement of this application, the drip irrigation ports drilled on multiple outer protection pipes are not completely the same. By controlling the number of drilled drip irrigation ports, different irrigation amounts per unit time are realized.

[0010] As a further improvement of this application, a spare through hole is drilled on the side wall of the outer protection pipe far from the communication port. A sealing unit is inserted into the spare through hole. One end of the sealing unit penetrates through the spare through hole and is fixedly connected with a water-soluble gel layer between the inner wall of the outer protection pipe. After the drip irrigation port is completely blocked, under the action of water pressure, the sealing unit is ejected, and the irrigation water flows out from the spare through hole to carry out the irrigation work, reducing the impact on the growth of fruit trees.

[0011] As a supplement to the further improvement of this application, a waterproof layer is fixedly connected to the lower end of the water-soluble gel layer. The waterproof layer includes multiple elastic fibers. Adjacent elastic fibers are wound around each other to form a three-dimensional space structure. During the irrigation process, the humidity inside the outer protection pipe will increase significantly. The waterproof layer composed of elastic fibers can effectively isolate the contact between the water-soluble gel layer and the humid air inside the outer protection pipe, greatly reducing the possibility of premature softening of the water-soluble gel layer, making the sealing unit not prone to premature failure.

[0012] As a supplement to the further improvement of this application, the waterproof layer is made of a degradable material, and the degradation period of the waterproof layer is twice the standard service life of the drip irrigation module, so that the scattered waterproof layer is not easy to form secondary pollution in the soil.

[0013] As a supplement to the further improvement of the present application, the hydrogel layer contains fluorescent pigments, and the fluorescent pigments are selected to be biodegradable. The fluorescent pigments will migrate to the soil surface under the transpiration of part of the irrigation water, and the growers can timely discover the blocked drip irrigation modules during daily inspections and arrange daily maintenance work to ensure the normal progress of the irrigation work.

[0014] As another improvement of the present application, the transition water tank includes a box body. There are an inlet and an outlet with opposite positions on the side wall of the box body. A partition plate is fixedly connected to the inner wall of the box body. The partition plate divides the inside of the box body into a transition chamber and a pressurization chamber. A solenoid valve is fixedly connected to the side wall of the partition plate. The solenoid valve connects the transition chamber and the pressurization chamber. A limiting floating plate is slidably connected to the upper half of the transition chamber. A limiting buckle matching the position of the limiting floating plate is fixedly connected to the lower end of the partition plate. An electric telescopic rod matching the position of the limiting floating plate is fixedly connected to the top wall of the box body. The dual design of the transition chamber and the pressurization chamber in the transition water tank realizes the adjustment of the pressurization effect, and different pressurizations can be carried out according to different irrigation requirements.

[0015] As a supplement to another improvement of the present application, the lower end of the electric telescopic rod is fixedly connected with a limiting push plate, and the limiting push plate is triangular in shape. When the electric telescopic rod limits the position of the limiting floating plate, the force distribution between the two is more uniform, and it is not easy to cause the local side turning and damage of the limiting floating plate under the action of water pressure.

[0016] To sum up, the irrigation water is pumped into the transition water tank by a water pump. After passing through the transition in the transition water tank, it is then transported to the drip irrigation module. Since the elastic coefficients of the compression springs in different drip irrigation modules are different, when none of the plurality of sealing plugs move to the limit position, at the same water pressure, the positions of the sealing plugs in different drip irrigation modules are not completely the same. By controlling the water pressure, it is realized that the sealing plugs in some drip irrigation modules do not move, while some communication ports are already connected to the connecting part, realizing differential irrigation. The number of drip irrigation openings drilled on the outer protection pipe can control the amount of water irrigated per unit time, realizing the irrigation of fruit trees with different irrigation requirements using a single drip irrigation water delivery pipe and reducing the irrigation cost.

[0017] At the same time, the dual design of the inner transition chamber and the pressurization chamber realizes the adjustment of the pressurization effect. When only slight pressurization is required for drip irrigation, the solenoid valve is in the open state, and the transition chamber is connected to the pressurization chamber. At this time, the overall air pressure change in the box body caused by the rise of the limiting floating plate is small, and the pressurization amplitude is small. When a higher pressurization requirement is required for drip irrigation, the solenoid valve is in the closed state, and the transition chamber is disconnected from the pressurization chamber. At this time, the overall air pressure change in the box body caused by the rise of the limiting floating plate is large, and the pressurization amplitude is large. Different pressurizations can be carried out according to different irrigation requirements. Description of the Drawings

Specific embodiments

[0031] The following will describe the three embodiments of the present application in detail with reference to the accompanying drawings.

[0032] The first embodiment:

[0033] Figures 1-3 and Figure 9 There is shown an irrigation facility for large-scale planting of tropical fruit trees, including a control terminal. The control terminal is signal-connected to an implementation layer and a detection layer. The implementation layer includes a canopy micro-spray module and a root-zone drip irrigation module, and the detection layer includes a light sensor, a humidity sensor, and a temperature sensor;

[0034] The root-zone drip irrigation module includes a water pump, a transition water tank 1, and a drip irrigation module 4. The water pump is connected to the transition water tank 1 and the transition water tank 1 is connected to the drip irrigation module 4 through a transmission water pipe 2.

[0035] In this embodiment, a "canopy micro-spray - root-zone drip irrigation" dual-level irrigation network is designed. The canopy micro-spray module adjusts the air humidity through atomization, and the root-zone drip irrigation module realizes precise supply.

[0036] Integrate soil humidity, light, and temperature data, and use the control terminal to construct an Internet-of-Things-based decision-making system to dynamically adjust the irrigation strategy: for example, start the evening irrigation mode during the drought stress period.

[0037] The second embodiment:

[0038] Figures 3-7 There is shown that the root-zone drip irrigation module includes a plurality of connecting tees 3 and drip irrigation modules 4. Adjacent two connecting tees 3 are connected to each other through a transmission water pipe 2. The drip irrigation module 4 includes a connecting portion 401 matching the connecting tee 3. The connecting portion 401 is threadedly connected to the connecting tee 3. A communication port 405 is drilled on the lower side wall of the connecting portion 401. A sealing plug 402 matching itself is slidably connected in the connecting portion 401. A compression spring 403 is fixedly connected between the sealing plug 402 and the bottom plate of the connecting portion 401. The elastic coefficients of the compression springs 403 in a plurality of drip irrigation modules 4 are not completely the same. When the compression spring 403 is in the original length state, the position of the sealing plug 402 matches that of the communication port 405. A limiting platform 404 is fixedly connected to the bottom plate of the connecting portion 401. An outer protection tube 406 is fixedly sleeved on the outside of the connecting portion 401. A plurality of drip irrigation ports 407 are drilled on the side wall of the outer protection tube 406 close to the communication port 405.

[0039] The drip irrigation ports 407 drilled on a plurality of outer protection tubes 406 are not completely the same. By controlling the number of drilled drip irrigation ports 407, different irrigation amounts per unit time are realized.

[0040] In the present embodiment, the irrigation water is pumped into the transition water tank 1 by a water pump, and then transported to the drip irrigation module after transition in the transition water tank 1. Since the elastic coefficients of the compression springs 403 in different drip irrigation modules 4 are different, when multiple sealing plugs 402 have not moved to the limit position, under the same water pressure, the positions of the sealing plugs 402 in different drip irrigation modules 4 are not completely consistent. In particular, by controlling the water pressure, it is possible to achieve that the sealing plugs 402 in some drip irrigation modules 4 have not moved, while some connecting ports 405 have been connected to the connecting portion 401, thereby achieving differential irrigation. The number of drip irrigation ports 407 opened on the outer protective tube 406 can control the amount of water irrigated per unit time, thereby achieving irrigation of fruit trees with different irrigation needs using one drip irrigation water supply pipeline, thereby reducing irrigation costs.

[0041] In particular, in the present application, the drip irrigation module 4 needs to be replaced regularly with the different growth stages of the fruit trees to adapt to the optimal irrigation needs of the fruit trees. Therefore, the drip irrigation module 4 needs to be buried in a shallower position. Compared with the use of a micro solenoid valve to control the amount of irrigation water, the drip irrigation module 4 in the present application is low in cost and easier to adapt to the relatively complex environment in the soil, and is not prone to corrosion and failure in a humid environment.

[0042] A spare through hole is drilled on the side wall of the outer protective tube 406 away from the connecting port 405 , a sealing unit 408 is inserted into the spare through hole, one end of the sealing unit 408 passes through the spare through hole and a hydrosol layer 409 is fixedly connected to the inner wall of the outer protective tube 406 .

[0043] See also Figure 8 When the drip irrigation module is in normal working state, the drip irrigation water flows out through the connecting tee 3, the connecting part 401, the connecting port 405 and the drip irrigation port 407 to achieve the purpose of drip irrigation. At the same time, since the outer protection tube 406 is a sealed structure, when the water in the outer protection tube 406 does not exceed the connecting port 405, as the irrigation water is further injected into the outer protection tube 406, the air above the liquid surface is compressed to form a temporary pressurized structure, which accelerates the rate of irrigation water flowing out of the drip irrigation port 407, and at the same time, it can also flush the drip irrigation port 407 to avoid the blockage of the drip irrigation port 407. After the drip irrigation port 407 is completely blocked, the irrigation water will quickly fill the outer protection tube 406, and the hydrosol layer 409 contacted by water will quickly soften and the connection will fail. At the same time, under the action of water pressure, the sealing unit 408 will be ejected, and the irrigation water will flow out from the spare through hole to carry out irrigation work, thereby reducing the impact on the growth of fruit trees.

[0044] The lower end of the hydrogel layer 409 is fixedly connected to a waterproof layer 410. The waterproof layer 410 includes a plurality of elastic fibers, and adjacent elastic fibers are intertwined with each other to form a three-dimensional spatial structure. During the irrigation process, the humidity inside the outer protection tube 406 will increase significantly. The waterproof layer 410 composed of elastic fibers can effectively isolate the contact between the hydrogel layer 409 and the humid air inside the outer protection tube 406, greatly reducing the possibility of the hydrogel layer 409 softening in advance, so that the sealing unit 408 is not prone to fail in advance. The waterproof layer 410 is made of a degradable material, and the degradation period of the waterproof layer 410 is twice the standard service life of the drip irrigation module 4, making it difficult for the scattered waterproof layer 410 to form secondary pollution in the soil.

[0045] The hydrogel layer 409 contains fluorescent pigments, and the fluorescent pigments are of a biodegradable type. The fluorescent pigments will migrate to the soil surface under the transpiration of part of the irrigation water. During the daily inspection process, the planting personnel can timely discover the blocked drip irrigation module 4 and arrange daily maintenance work to ensure the normal progress of the irrigation work.

[0046] In addition, in this application, sealing gaskets are provided at the joints between the plurality of transmission water pipes 2 and the connecting tee 3, between the connecting portion 401 and the connecting tee 3, and between the sealing unit 408 and the outer protection tube 406, increasing the overall sealing effect of the drip irrigation system and reducing the possibility of irrigation water leakage.

[0047] The third implementation method:

[0048] Figures 9-11 The shown transition water tank 1 includes a tank body 101. Water inlet 102 and water outlet 103 which are opposite in position are drilled on the side wall of the tank body 101. The tank body 101 is connected to a water pump through the water inlet 102 and a transmission water pipe 2, and the tank body 101 is connected to the connecting tee 3 and the drip irrigation module 4 through the water outlet 103 and a transmission water pipe 2. A partition plate 104 is fixedly connected to the inner wall of the tank body 101. The partition plate 104 divides the inside of the tank body 101 into a transition chamber and a pressurization chamber. An electromagnetic valve 105 is fixedly connected to the side wall of the partition plate 104. The electromagnetic valve 105 connects the transition chamber and the pressurization chamber. A limit floating plate 107 is slidably connected to the upper half of the transition chamber. A limit buckle 106 which is matched with the position of the limit floating plate 107 is fixedly connected to the lower end of the partition plate 104. An electric telescopic rod 108 which is matched with the position of the limit floating plate 107 is fixedly connected to the top wall of the tank body 101.

[0049] In this application, after the irrigation water enters the transition water tank 1, it will accumulate in the transition water tank 1 and push the limit floating plate 107 to float until it contacts the lower end of the electric telescopic rod 108, forming a double pressure boost of the water level height and air pressure inside the box body 101 for the irrigation water transmitted to the drip irrigation module 4, making the drip irrigation water flow more smoothly. Among them, the double design of the transition chamber and the pressure boost chamber in the transition water tank 1 realizes the adjustment of the pressure boost effect. When only slight pressure boost is required for drip irrigation, the solenoid valve 105 is in the open state, and the transition chamber is connected to the pressure boost chamber. At this time, the overall air pressure change in the box body 101 caused by the rise of the limit floating plate 107 is small, and the pressure boost amplitude is small. When higher pressure boost is required for drip irrigation, the solenoid valve 105 is in the closed state, and the transition chamber is disconnected from the pressure boost chamber. At this time, the overall air pressure change in the box body 101 caused by the rise of the limit floating plate 107 is large, and the pressure boost amplitude is large. Different pressure boosts can be carried out according to different irrigation requirements.

[0050] The length adjustment of the electric telescopic rod 108 can limit the extreme floating position of the limit floating plate 107, and then adjust the extreme pressure boost amplitude, which is convenient for controlling whether the drip irrigation module 4 conducts irrigation.

[0051] The lower end of the electric telescopic rod 108 is fixedly connected with a limit push plate 109. The limit push plate 109 is triangular in shape, so that when the electric telescopic rod 108 limits the limit floating plate 107, the force distribution between the two is more uniform, and it is not easy to cause the local side-turning damage of the limit floating plate 107 under the action of water pressure.

[0052] Particularly, for the convenience of display, the various structures in this application are not drawn strictly according to the ratio in the specification drawings. Those skilled in the art can reasonably design the sizes and shapes of the various structures according to actual use requirements to meet the use requirements of this application. This is common knowledge for those skilled in the art, so it is not disclosed in detail in this application.

[0053] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application does not limit the protection scope thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
