Description

Technical Field

[0001] The invention relates to an automatic watering and maintenance system, in particular to an automatic water-generating and tree-planting and grass-planting system without watering and maintenance, belonging to the technical field of water-saving irrigation. Background Art

[0002] With the intensification of global climate change and human activities, land desertification and mountain slope degradation are becoming increasingly serious, especially in arid and semi-arid areas. Vegetation restoration in sandy land and mountain slopes faces huge challenges. Traditional vegetation restoration methods rely on manual watering and regular maintenance, which not only consumes a lot of water resources and labor costs, but is also difficult to sustain in extreme environments. Therefore, the development of an automated planting system that can achieve watering-free and maintenance-free has become a key technical requirement for solving the problem of ecological restoration of sandy land and mountain slopes.

[0003] The ecological environment of sandy land and mountain slopes is extremely fragile, mainly manifested in poor soil, lack of water, severe wind erosion and low vegetation coverage. Traditional vegetation restoration methods usually require a large amount of water resources for irrigation. In arid areas, water resources themselves are extremely scarce. Over-reliance on artificial watering is not only unsustainable, but may also aggravate the problem of water shortage. In addition, due to the steep terrain and poor soil stability of mountain slopes, artificial maintenance is difficult and the vegetation survival rate is low. Therefore, how to achieve autonomous growth of vegetation and ecological restoration in extreme environments has become the focus of current research.

[0004] Air condensation water collection technology is a method of extracting water from the atmosphere, which is particularly suitable for arid areas. In the prior art, such as the intelligent multiple irrigation device based on adsorption air water extraction disclosed by announcement number CN217905562U, by setting up a water collection box, an air suction mechanism, an adsorption box, a serpentine condenser and a water supply mechanism and other components, the water contained in the outside air can be converted into a usable water source for irrigation by using the mutual cooperation of each component, thereby solving the problem of water shortage. The water outlet can be combined with different irrigation methods according to the environment, such as drip irrigation, sprinkler irrigation, etc., but when the existing device performs air condensation and water separation, it uses the high temperature of the desert surface during the day, and there is a temperature difference between the desert deep layer, and then uses the temperature difference to achieve condensation and water collection, but at night, the temperature of the desert surface will drop sharply, so condensation and water collection cannot be achieved at night, that is, the water collection efficiency of the entire device is low, and it cannot meet the watering needs of plants. Secondly, an air water source automatic water collection irrigation device disclosed by announcement number CN211379106U. The invention comprises energy supply, water collection, irrigation and control devices; the energy supply device comprises photovoltaic solar collector panels and batteries; the water collection device comprises water collection boxes, electric fans and semiconductor condensation plates; the irrigation device comprises water storage tanks, filter screens, absorbent cotton and water pipes; the control device comprises PLC controllers, pressure sensors and valves; the energy supply device supplies power to other devices; the condensation plate is placed vertically, and a water storage tank is placed below; the water pipe is connected to the water storage tank and controlled by a valve; the absorbent cotton is inserted into the water pipe. The air moisture is collected by condensation and liquefaction, and then the moisture is automatically transported by capillary action for crop growth, thereby realizing energy-saving, environmental protection and efficient agricultural irrigation. The existing device uses absorbent cotton to irrigate plants, but as the plants grow, the plant roots will penetrate into the deeper soil layer, and the length of the absorbent cotton set by the existing device is fixed, so it is impossible to irrigate the plant roots evenly, and the root system that continuously penetrates into the soil layer during the growth of the plant cannot be expanded accordingly. There is a lack of precise irrigation function for the tree roots, and it is difficult to achieve targeted water and nutrient supply. Summary of the invention

Since the installation position of the spiral condensation tube is located at the lower part of the tube body of the condensation water collection tube, and the lower part of the tube body of the condensation water collection tube is buried in the sand layer of the desert, as the temperature of the tube body of the spiral condensation tube decreases, the moisture in the desert air can be condensed into water droplets and drip downward, and be collected by the water collection tank, so as to realize the collection of moisture in the air, and the desert air after condensation and dehydration is discharged through the bottom end of the spiral condensation tube, and the desert air can flow upward through the exhaust pipe.

Due to the installation position of the spiral condenser tube 14 It is located at the lower part of the condensation and water collection outer tube 1, and the lower part of the condensation and water collection outer tube 1 is buried in the sand layer of the desert.

At this time, the desert air is in a low-temperature state. Therefore, the low-temperature desert air in the exhaust pipe 17 can form convection with the desert air in the spiral condenser 14 and perform heat exchange, which can further increase the cooling rate of the desert air in the spiral condenser 14 and increase the air condensation rate. The plate-type condensation water collection unit includes a condensation water collection corrugated plate 2 and a water guide box 4. The water guide box 4 is connected to the inclined bottom end of the condensation water collection corrugated plate 2.

The bottom end of the water guide box 4 is connected with a water guide pipe 42, and the bottom end of the water guide pipe 42 is connected with the water collection tank 5. During the daytime, the wave crest hydrophobic area 21 reduces the plate body temperature through its high reflective characteristics, and the wave trough hydrophilic area 22 absorbs trace water vapor in the air to form a thin water film pre-cooling surface.

Several water-absorbing cotton strips 73 are connected around the tank body of the buffer tank 71. The drip irrigation pipe 72 is vertically connected to the bottom end of the buffer tank 71. The water in the water collecting tank 5 can be transported to the buffer tank 71 through the delivery pipe 6 and the connecting hose 7, and then the plant roots can be drip-irrigated through the drip irrigation pipe 72. At the same time, part of the water will be used to moisturize the soil at the root of the plant through the water-absorbing cotton strip 73.

The body of the water guide pipe 42 is connected with a water guide solenoid valve 43, so that the condensed water in each trough hydrophilic area 22 can be respectively dripped into the matching water guide funnel 41, and the water guide funnel 41 can be more easily drained through the drainage grooves 44 provided on the inner wall. The flow of condensed water can then cause the condensed water to be collected into the water guide box 4, and the water guide solenoid valve 43 can control the opening and closing of the water guide pipe 42, so that when the water collecting corrugated plate 2 condenses and collects water at night, the water guide solenoid valve 43 is opened to make the water guide pipe 42 in a connected state, and the collected water can flow into the water collection tank 5 for storage. During the day, the water guide solenoid valve 43 is closed to make the water guide pipe 42 in a blocked state, and water evaporation due to the high temperature in the desert can be avoided.

[0027] Furthermore, a water pump 51 is arranged in the water collecting tank 5, and the water inlet end of the water pump 51 is connected to a water inlet pipe 52.

The nutrient solution can be transported while watering the trees and plants, so as to meet the growth needs of the trees and plants and realize maintenance-free planting of the trees and plants. The water level gauge 53 can control the opening and closing of the water pump 51 when the water level in the water collecting tank 5 reaches the threshold set by the water level gauge 53, so that the collected water in the water collecting tank 5 can be flexibly transported.

The nozzle position of the drip irrigation pipe 72 in the buffer tank 71 is higher than the opening position of the perforations 74. When water is transported to the buffer tank 71, since the nozzle position of the drip irrigation pipe 72 in the buffer tank 71 is higher, some water will accumulate in the buffer tank 71 after the drip irrigation is finished. Then, the water can be slowly released into the soil through the action of the water-absorbing cotton strip 73, so as to realize continuous moisture retention of the soil at the root part of the plant.

As the tree grows, the root system gradually penetrates deep into the soil, and the water-soluble film 76 will gradually dissolve after a period of time. At this time, the drip irrigation pipe 72 can adapt to the growth of the tree root system for drip irrigation at different depths.

[0029] Furthermore, the power supply assembly includes a solar panel 8, a support plate 81, a connecting rod 82, a wireless network card controller 83 and an energy storage battery 84.

The wireless network card controller 83 and the energy storage battery 84 are fixedly connected to the rod body of the connecting rod 82. The solar panel 8 and the energy storage battery 84 are electrically The energy storage battery 84 is electrically connected to the electrical components of the system, the wireless network card controller 83 is connected to the electrical components of the system for signal transmission, the solar panel 8 is tilted to receive more sunlight, thereby improving the efficiency of solar power generation, and the wireless network card controller 83 can wirelessly control the electrical components, and the energy storage battery 84 is powered for the electrical components of the system, ensuring that the system can automatically perform air water collection and drip irrigation operations without human control.

[0030] Working principle: The plate-type condensation water collection unit can be used to condense and collect desert air at night. The air intake inner pipe 12 guides the desert air to the spiral condenser 14. Since the installation position of the spiral condenser 14 is located at the lower part of the condensation water collection outer pipe 1, and the lower part of the condensation water collection outer pipe 1 is buried in the sand layer of the desert, as the temperature of the spiral condenser 14 decreases, the moisture in the desert air can be condensed into water droplets and drip downward, and be collected by the water collection tank 5, so as to collect the moisture in the air. The desert air after condensation and dehydration is discharged through the bottom end of the spiral condenser 14, and the desert air can be discharged through the exhaust pipe 17. The desert air is in a low-temperature state at this time, so the low-temperature desert air in the exhaust pipe 17 can form convection with the desert air in the spiral condenser 14 and perform heat exchange, which can further increase the cooling rate of the desert air in the spiral condenser 14. The tubular condensation and water collection unit can be used to condense and collect water from the desert air during the day. During the day, the crest hydrophobic area 21 reduces the plate temperature through its high reflective properties, and the trough hydrophilic area 22 absorbs trace amounts of water vapor in the air to form a thin water film pre-cooling surface. During the night, the plate temperature of the condensation and water collection corrugated plate 2 is further cooled to below the ambient temperature, and water vapor in the air is preferentially condensed in the trough hydrophilic area 22. The condensed water droplets in the hydrophobic area 21 of the wave crest slide into the water guide groove 24 provided in the hydrophilic area 22 of the wave valley, and flow downward along the inclination angle of the condensed water collection corrugated plate 2, and are merged into the water guide box 4 together, and the condensed water in the water guide box 4 is transported to the water collection tank 5 through the water guide pipe 42, that is, the desert air can be collected at night, so that the system can collect water all day long, and the water collection efficiency in the desert is maximized, and the nutrient solution transported by the nutrient solution transport component can be mixed with the water in the water collection storage end of the water collection component, and drip irrigation is performed on the root system of the plant through the drip irrigation component, and the transport pipe 6 and The connecting hose 7 transports the water in the water collection tank 5 to the buffer tank 71, and then the plant roots can be drip-irrigated through the drip irrigation pipe 72. At the same time, part of the water will be used to moisturize the soil at the root of the plant through the absorbent cotton strip 73. The two irrigation methods are combined to achieve better irrigation and water-saving effects. It can be better used in water-scarce areas in the desert to maintain the growth of trees and plants, realize automatic water production and automatic maintenance of plants, and the power supply component can provide the required electricity for each component of the system, so that the system can generate electricity and collect water for drip irrigation in the desert, ensuring that no excessive human operation is required during use.
