Description

Technical Field

[0001] The invention relates to the technical field of water-saving irrigation, and in particular to an intelligent water collection and irrigation system based on solar energy. Background Art

[0002] When plants transpire, they release a large amount of water into the air, causing the plants to lose a large amount of water, which often leads to water loss and dehydration damage. However, transpiration can promote the absorption and conduction of water by plants, forming a transportation system inside the plants. Nutrients are transported from the roots to the upper part of the plant along with the water, and organic matter is also transported within the plant. At the same time, transpiration can effectively reduce the temperature of the leaves and maintain the plant's physiologically appropriate body temperature.

[0003] Furthermore, the roots of plants are the main part of absorbing water. They absorb water from the soil through the cells on the surface of the roots and transport it to the stems, leaves and other parts of the plants. If water is poured directly on the leaves of the plants, this may cause damage to the leaves while the roots remain dry and unable to absorb enough water. In addition, excessive watering may also cause root rot. At the same time, the nature of the soil will also affect the way we water. For example, clay requires more water to stay moist, while sandy soil is more prone to drying out.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] like Figure 1-3 As shown, a solar-based intelligent water collection and irrigation system includes a frame 3 and a PLC control cabinet. The outer surface of the frame 3 is provided with a film, which can control the water generated by the plant through transpiration inside the frame to prevent water loss. A solar panel 5 is installed on the top of the outer surface of the frame 3. The solar panel 5 is electrically connected to the battery through a controller and a converter. The battery is charged through the solar panel. With a small amount of municipal electricity, the water requirement of the plants inside the frame is met.

[0033] Passive rainwater collection components are installed at both ends of the outer surface of the frame 3, which can collect precipitation in rainy and snowy weather;

[0034] An active dew collection assembly is installed on the top of the inner surface of the frame 3, which can cool the water vapor generated by plant transpiration and condense it into water droplets, which drip on the plants to ensure the water requirement of the plants;

[0035] The passive rainwater collection component and the active dew water collection component are both connected to the water distribution component. The water distribution component is buried in the soil layer and can accurately replenish water from the roots of plants to prevent a large amount of water from evaporating when water is irrigated to the soil surface, thereby affecting the absorption of the roots;

[0036] The frame 3 and the soil layer are also equipped with detection components, which can detect the moisture and minerals inside the soil layer and provide data support for the precise water supply operation of the plant roots;

[0037] The passive rainwater collection component, the active dew water collection component and the detection component are all electrically connected to the PLC control cabinet.

[0038] Specifically, the passive rainwater collection component includes a water tank 1 and a gutter 4, wherein the gutter 4 is installed on both sides of the arched top of the frame 3, and the gutter 4 is connected to the water inlet of the water tank 1 through the rainwater pipe 2. In rainy and snowy weather, water will flow along the film on the arched top of the frame to the gutter for collection, and flow through the rainwater pipe in the water tank for collection and standby. Furthermore, the water tank is buried underground, which can effectively prevent the water tank filled with water from being frozen and cracked in cold weather, affecting the service life of the water tank. Furthermore, a one-way valve is installed at the water inlet of the water tank 1 to prevent the loss of water in the water tank; further, a liquid filling port is also installed on the rainwater pipe, which can facilitate the addition of liquid medicine and fertilizer into the water tank;

[0039] A water pump is installed inside the water storage tank 1, and the water pump is connected to the water distribution assembly. The water, liquid medicine or / fertilizer in the water storage tank is supplied to the roots of the plants through the water pump to promote rapid absorption by the plants;

[0040] Furthermore, a liquid level meter is installed in the water tank, and the liquid level meter is electrically connected to the PLC control cabinet to monitor the water volume in the water tank.

[0041] Specifically, the active dew water collection assembly includes a working main pipe 8, the inlet of the working main pipe 8 is connected to the outlet of a compressor 9, and the inlet of the compressor 9 is connected to an underground pipe 10;

[0042] The working main pipe 8 is connected to the working branch pipe 6, and a fin 7 is installed in the middle of the working branch pipe 6;

[0043] The buried pipe 10 is buried deep underground;

[0044] The working main pipe and the buried pipe are filled with refrigerant. When working, the compressor transmits the low-temperature refrigerant inside the working main pipe and circulates it to the working branch pipe through the working main pipe. At this time, the pipe body temperature of the working main pipe and the working branch pipe drops, and the water vapor inside the frame is pre-condensed into water droplets, which drip onto the soil. The fertilizer or liquid medicine on the surface of the soil can flow to the roots of the plants with the penetration of the water droplets, which is convenient for the plants to accelerate the absorption of the liquid medicine and fertilizer;

[0045] At the same time, the high-temperature refrigerant flows to the buried pipe driven by the compressor, releases heat through the contact between the buried pipe and the underground soil, and transfers the heat to the inside of the soil, so that the high-temperature refrigerant inside the buried pipe is cooled down;

[0046] When the refrigerant flows in the working main pipe and the buried pipe, it can also adjust the temperature inside the frame through the process of absorbing and releasing heat, control the temperature difference between day and night inside the frame, and promote plant growth. The higher temperature during the day is conducive to increasing the photosynthetic rate under strong light and providing sufficient materials for growth; the lower temperature at night can reduce the consumption of organic matter by respiration.

[0047] Specifically, a mist-catching net is also installed on the fin 7. The fin can expand the heat exchange area, and can make the water vapor inside the frame condense evenly and fall on the plants to achieve watering. The mist-catching net can further convert the water vapor and can also collect the water vapor by itself when the compressor is not working. The time period for the mist-catching net to collect water vapor by itself is generally at night, and the water droplets dripping on the leaves of the plants will not cause damage to the leaves under the action of sunlight.

[0048] Specifically, the water distribution assembly includes a water distribution pipe 11 and a water storage tank 12. The water distribution pipe 11 is evenly arranged below the soil, and the water distribution pipe 11 is connected to the water storage tank 12.

[0049] The side walls of the water distribution pipe 11 and the water storage tank 12 are both provided with micropores, and the interior of the water storage tank 12 is filled with a water retaining agent;

[0050] When working, the water pump in the water tank supplies water to the water distribution pipe and the water storage tank. During the water supply process, the micropores on the water distribution pipe and the water storage tank will overflow water into the soil to meet the water needs of the plant roots. Furthermore, the water retaining agent in the water storage tank can store water, repeatedly release and absorb water, and achieve the effects of soil improvement, water conservation and drought resistance.

[0051] Specifically, the detection component includes an air humidity sensor and a soil three-parameter sensor. The air humidity sensor is installed in the internal space of the frame 3, and the soil three-parameter sensor is buried in the soil. The air humidity sensor and the soil three-parameter sensor are both electrically connected to the PLC control cabinet.

[0052] When the air humidity sensor detects that the humidity in the air is greater than the set value, the air humidity sensor feeds back a signal to the PLC controller, and the PLC controller controls the compressor to work, so that the refrigerant circulates in the working main pipe and the buried pipe, and the water vapor condenses into water droplets on the fins and the mist catcher net. Under the action of gravity, the water droplets penetrate downward and are absorbed and stored by the water retaining agent in the water storage tank, reducing the air humidity, enhancing the transpiration of plants, and effectively improving the ability of plants to transport nutrients;

[0053] The soil three-parameter sensor can monitor the temperature, humidity and conductivity of the soil, and feed back the monitoring signal to the PLC control cabinet, and control the start and stop of the water pump through the PLC controller to ensure that the moisture, temperature and conductivity in the soil are within the normal range, avoiding excessive or low moisture, which will inhibit the respiration, photosynthesis, growth and other life activities of the plant; ensuring that the soil moisture is appropriate so that the root water absorption and leaf transpiration are in a balanced state.

[0054] Working process of the present invention:

[0055] In summer, rainwater is collected into water tanks through gutters and rainwater pipes for standby use. The three-parameter soil sensor buried in the soil monitors the soil's dielectric constant. When the soil humidity is lower than the preset value, the PLC control cabinet sends a work instruction to the water pump in the water tank based on the data fed back by the liquid level meter, and gives priority to supplying the rainwater collected in the water tank to the inside of the water distribution pipe, so as to replenish the roots through microporous seepage, which can effectively reduce the use of groundwater and municipal water.

[0056] When the liquid level meter detects that the water pump in the water tank is not enough to pump water into the water distribution pipe, the liquid level meter will feedback a signal to the PLC control cabinet. At this time, the PLC controller will no longer send a work instruction to the water pump to prevent the water pump from idling and affecting the service life of the water pump. With the support of time and temperature data, the PLC control cabinet sends a signal to the compressor to control the compressor to work in the morning or evening, so that the refrigerant circulates in the working main pipe and the buried pipe to achieve heat absorption and heat release. On the one hand, it can improve the condensation efficiency of water vapor to ensure the water volume, and on the other hand, it can prevent the sun from adversely affecting the plants through the water droplets on the leaves.

[0057] Furthermore, the mist capture net can assist in completing the water vapor capture operation and complete the watering of the plants under the action of gravity;

[0058] In winter, snowfall will cover the top of the frame, which will have a certain impact on the photosynthesis of plants. When the water vapor in the frame rises, it will freeze on the outer surfaces of the working main pipe, working branch pipe and fins. Furthermore, snowfall cover and ice will threaten the structural safety of the frame. At this time, the PLC control cabinet sends a work instruction to the compressor, and the compressor will flow the high-temperature refrigerant from the buried pipe to the working main pipe and working branch pipe, so that the pipe wall temperature of the working main pipe and working branch pipe will increase, and through heat transfer, the temperature of the fins and the mist catcher will be further increased, and the ice layer on the outside of the pipe wall and the snow outside the film will be melted. After the ice layer melts, the water droplets supply water to the plants. After the snow melts, it is collected in the water storage tank through the gutters and rainwater pipes for standby use.
