Description

TECHNICAL FIELD

[0001] The present application relates to the field of fresh water acquisition technology, in particular to an automatic control adsorption type air water taking drip irrigation system. BACKGROUND

[0002] Water resources are severely short in our region, and water shortage becomes one of the main factors restricting the development of agriculture and forestry in our region. Due to the widespread waste of water, the irrigation water use efficiency is only 30% to 40%. Drip irrigation is an advanced water-saving irrigation technology, which has many advantages, such as water saving, fertilizer saving, reducing land preparation cost, salt removal, labor saving, improving afforestation survival rate and growth, etc. In the drip irrigation system, irrigation water is uniformly delivered to the dripper on the pipe, and then slowly dripped to the soil in the root zone of the tree, and penetrates to the root system. Reducing deep seepage and evaporation, avoiding runoff loss. Water resource utilization rate can be increased to more than 90%, saving water by about 60% compared with conventional irrigation.

[0003] Since the drip irrigation only locally wets the upper body, it basically does not destroy the upper soil structure, so that the water, fertilizer, air and heat inside the upper soil can always be kept in a good state suitable for crop growth. Practice has proved that in drought and water shortage areas, the use of drip irrigation water-saving technology will obtain significant water-saving and yield-increasing effect, which has extremely important significance for the construction of water-saving ecological environment in our region.

[0004] Nowadays, with the development of productivity, drip irrigation has become an indispensable part of agriculture, but it is still very difficult to carry out agricultural drip irrigation in hot and high temperature environment. In order to realize the smooth progress of drip irrigation under adverse environmental conditions, the most fundamental thing is how to obtain water and electricity conveniently and quickly.

[0005] The combination of solar energy and adsorption type air water taking drip irrigation technology is an advanced drip irrigation method today, which uses solar energy to produce electric energy and heat energy respectively. And the heat energy is used as driving force to produce liquid water from the adsorption bed and condenser. This technology uses solar energy and the uneven distribution of water vapor in the air over time to adsorb water vapor at night when water vapor is abundant and solar energy is lacking, and to produce liquid water and electric energy during the day when water vapor is lacking and solar energy is abundant. These water and power resources are used by drip irrigation equipment to realize self-production of water and electricity for drip irrigation agriculture in the desert.

[0006] Through retrieval, the patent document CN102943503A discloses a desert rainwater collecting and storing drip irrigation device, which comprises V-shaped water collecting grooves and rainwater collecting branch pipes which are uniformly distributed on the upper surface of a brick body supported by a brick body support, a rainwater collecting main pipe is arranged on the side of the rainwater collecting branch pipes and is connected to a lower water storage tank, the lower water storage tank is connected to an upper water storage tank through a water pumping pipe, and the upper water storage tank is connected to the brick body through a drip irrigation main pipe. The device uses a large water collecting platform to collect extremely small amount of rainwater in a desert area, and has the disadvantages of large occupied area, low space utilization rate, unstable water resource acquisition, and the need of external power supply when the device is used. SUMMARY

[0007] In view of the defects in the prior art, the purpose of the present application is to provide a solar water and electricity self-production drip irrigation device.

[0008] The present application proposes a solar adsorption water and electricity self-production technology, which produces water resources and electrical energy by comprehensively using solar energy, improves the utilization rate of solar energy, and simultaneously stably supplies water for the drip irrigation device.

[0009] An automatic control adsorption air water taking drip irrigation system, comprising: an adsorption air water taking device, an automatic control transmission device and a drip irrigation device; the adsorption air water taking device comprises:

[0010] A solar panel;

[0011] A moisture absorbing assembly arranged on the back side of the solar panel, the moisture absorbing assembly having an evaporation working state and a moisture absorbing working state;

[0012] A condensing assembly, which condenses water vapor generated by the evaporation of the moisture absorbing assembly when the moisture absorbing assembly is in the evaporation working state;

[0013] A water collecting tank for collecting condensed water generated by the condensing assembly;

[0014] The automatic control transmission device is used for switching the moisture absorbing assembly between the evaporation working state and the moisture absorbing working state.

[0015] The solar panel can be selected from various commercially available photovoltaic panels. The solar panel can not only provide electrical energy for the whole device through a power supply line, but also provide electrical energy for other external devices through the power supply line. When the photovoltaic panel generates electricity under the sun, the unconverted light energy will be converted into waste heat, which can provide heat for the evaporation of water vapor in the moisture absorbing assembly fixed thereon, so that the water vapor is released, and the moisture absorbing agent in the moisture absorbing assembly is regenerated and desorbed at the same time.

[0016] The moisture absorption component can adopt any existing structure with water vapor adsorption function. In an alternative, the moisture absorption component is composed of a wrapping material (such as various existing porous wrapping films) and a moisture absorption material encapsulated in the wrapping material. The moisture absorption material is composed of a porous substrate and a moisture absorption salt.

[0017] The porous substrate can be active carbon fiber felt (ACFF), silica gel, zeolite, activated carbon or activated alumina; the moisture absorption salt can be lithium chloride, calcium chloride, strontium chloride, lithium bromide or strontium bromide; and the wrapping film can be a polytetrafluoroethylene (PTFE) film or the like that can be permeated by water vapor but blocks liquid.

[0018] The moisture absorption component is prepared in two steps:

[0019] (1) Preparation of the moisture absorption material (or the moisture absorption agent): the porous substrate is immersed in an aqueous solution of the moisture absorption salt and dried to obtain the moisture absorption material. In this step (1), the immersion and drying can be performed in multiple steps as needed.

[0020] (2) Preparation of the moisture absorption component: the moisture absorption material is wrapped with the wrapping film and encapsulated using an existing encapsulation method (such as hot melt adhesive encapsulation) to obtain the moisture absorption component.

[0021] The moisture absorption salt adhered to the porous substrate forms the moisture absorption agent, which is wrapped with the wrapping film. The moisture absorption salt chemically adsorbs water vapor absorbed by the porous substrate to form a hydrated salt. When the relative humidity of the environment contacted by the moisture absorption agent exceeds the relative deliquescence humidity of the moisture absorption agent, the hydrated salt inside further absorbs water to undergo a deliquescence reaction, and water vapor is continuously absorbed by the liquid film of the saturated salt solution on the surface of the hydrated salt particles to form a saturated salt solution. The polytetrafluoroethylene film wrapped on the surface of the moisture absorption agent has good air permeability, water resistance and strong chemical stability. The moisture absorption agent is encapsulated in the PTFE film, and water vapor can be permeated through the film and adsorbed by the adsorbent material. This film can prevent the leakage of the salt solution and maintain the cyclic adsorption capacity of the material.

[0022] As a preferred embodiment, the water and electricity dual production panel is further provided with an upper top shell, and the solar panel and the moisture absorption component are fixed to the upper top shell to form an integrated structure. The water and electricity dual production panel is detachably fixed to the condensation component. When water vapor needs to be adsorbed, the integrated structure of the water and electricity dual production panel and the condensation component can be separated, and when evaporation is needed, the two can be sealed and fixed again.

[0023] As a preferred embodiment, the condensation component comprises:

[0024] The lower bottom shell is provided with a water outlet.

[0025] The rectifier plate is fixed in the lower bottom shell and has an air layer between the rectifier plate and the inner wall of the lower bottom shell;

[0026] The condenser is fixed on the outer wall of the lower bottom shell.

[0027] Preferably, the upper top shell and the lower bottom shell are provided with the magnetic attraction assembly II. The magnetic attraction assembly II can use electromagnets. When the electromagnets in the magnetic attraction assembly II are powered, the upper top shell and the lower bottom shell can be attracted.

[0028] The upper top shell and the lower bottom shell are provided with sealing mechanisms for sealing and fixing the two. Further preferably, the sealing mechanisms are sealing grooves and sealing protrusions arranged circumferentially on the abutting surfaces of the upper top shell and the lower bottom shell and sealingly matched with each other. The sealing protrusions and the sealing grooves are matched with each other to form a sealing structure, providing sealing capability for the device.

[0029] The upper top shell and the lower bottom shell can seal and fix the solar panel and the moisture absorption assembly, and can also fix the rectifier plate and the condenser, while providing a condensing surface for the condenser to quickly condense and collect water vapor.

[0030] The upper top shell and the lower bottom shell are provided with positioning grooves for installing the magnetic attraction assembly II. The required sensor signal terminals and electrical signal terminals are also provided. The upper top shell is a hollow frame structure with an inner diameter slightly smaller than the outer diameter of the solar panel, so as to fix the solar panel. The moisture absorption assembly is generally a plate structure and is fixed to the back side of the solar panel by an adhesive (or other fixing methods such as threaded fixing and clamping). The top of the rectifier plate can also be fixed to the solar panel by various methods. The condenser can be fixed to the bottom of the lower bottom shell by heat dissipation fins and an adhesive (or other fixing methods such as threaded fixing and clamping).

[0031] When the moisture absorption assembly is in an evaporation working state, the solar panel converts solar energy into electrical energy. At this time, the solar panel, the moisture absorption assembly, and the condensing assembly are fixed to each other by the upper top shell and the lower bottom shell.

[0032] The magnetic attraction assembly I and the magnetic attraction assembly II each have a matched electromagnet pair. The corresponding components are attracted and opened by electrical signals.

[0033] Preferably, the device further includes a support frame, and the lower bottom shell and the condenser are fixed to the support frame. The support frame can adjust the included angle with the ground to change the angle of the photovoltaic panel receiving solar radiation and provide support for the overall device. The upper top shell and the lower bottom shell wrap the electromagnets, the photovoltaic panel, the moisture absorption assembly, and the rectifier plate. The lower bottom shell is in close contact with the condenser.

[0034] The photovoltaic panel (i.e. solar panel) generates electricity under the sun, and the unconverted light energy will be produced as waste heat. The waste heat will provide heat to the closely attached moisture absorption assembly, causing the moisture absorption agent inside the moisture absorption assembly to undergo a regeneration desorption process. This process is the reverse of the water absorption process, and the moisture absorption agent will continuously evaporate water vapor and become a saturated solution. At high temperatures, the saturated solution gradually releases crystalline hydrate, and if the temperature is raised again, the crystal water can be separated from the crystalline hydrate and diffuse in the form of gas through the rectifier plate in the condensing assembly, filling the cavity between the rectifier plate and the bottom plate of the lower bottom shell. The condensing assembly condenses the water vapor diffused in the cavity between the rectifier plate and the bottom plate of the lower bottom shell, and flows out through the water outlet on the side of the lower bottom shell bottom plate.

[0035] As a preferred, the automatic control transmission device comprises:

[0036] Parallel guide rails;

[0037] A suction cup I is slidably arranged on the parallel guide rails and can reciprocally move, and is used to suction and fix the moisture absorption assembly that needs to enter the moisture absorption working state and transport it to the conveying belt setting position;

[0038] Vertical guide rails;

[0039] A suction cup II is slidably arranged on the vertical guide rails and can reciprocally move, and is used to suction and fix the moisture absorption assembly that needs to enter the evaporation working state and transport it to the adsorption air water taking device setting position;

[0040] A conveying belt receives the moisture absorption assembly released on the suction cup I, and simultaneously transports the moisture absorption assembly that needs to enter the evaporation working state to the corresponding position of the suction cup II.

[0041] In actual work, the solar panel and the moisture absorption assembly are a fixed integrated structure (also referred to as a water and electricity dual production panel), and the suction cup I and the suction cup II directly suction the integrated structure of the solar panel and the moisture absorption assembly to switch the working state of the moisture absorption assembly. The suction cup I and the suction cup II are provided with electromagnet assemblies.

[0042] The suction cup I can suction and release the water and electricity dual production panel with an electromagnet by controlling the electromagnet it has. The parallel guide rails are used to move the upper working suction cup I and provide limiting, guiding and supporting.

[0043] The left and right movement of the suction disc I can be realized by parallel guide rails, so that any one adsorption assembly in the evaporation working state which does not meet the moisture absorption requirement can be replaced. The parallel guide rails are provided with a driving motor (such as a screw stepper motor or other stepper motor) matched with the suction disc I and a corresponding transmission member (transmission screw or transmission gear) at the same time. The parallel guide rails and the suction disc I are provided with a guide groove structure which can ensure the movement in the set direction and will not slide off.

[0044] The suction disc I, the suction disc II and the water and electricity dual production plate are all provided with a magnetic attraction assembly I; the water and electricity dual production plate and the condensation assembly are both provided with a magnetic attraction assembly II; the magnetic attraction assembly I and the magnetic attraction assembly II are both electromagnets. When the suction disc I uses the magnetic attraction assembly I to attract the corresponding moisture absorption assembly, the magnetic attraction assembly II releases the corresponding adsorption assembly at the same time, which can be controlled by the electric signal of the controller.

[0045] The vertical guide rail is also provided with a vertical driving motor for driving the suction disc II to move up and down. When the suction disc II transports the moisture absorption assembly (which is actually an integral structure of the water and electricity dual production plate) which needs to enter the evaporation working state to the set position of the adsorption type air water taking device, the corresponding magnetic attraction assembly I of the suction disc II is disconnected from the attraction force, the magnetic attraction assembly II at the corresponding position is electrified to attract the corresponding moisture absorption assembly, and the working state switching of the moisture absorption assembly is completed.

[0046] As a preferred, the suction disc II is a rectangular frame structure, and the inner diameter size matches the outer diameter size of the water and electricity dual production plate. When the water and electricity dual production plate is attracted, the attraction effect position of the water and electricity dual production plate is the side wall of the water and electricity dual production plate, that is, the water and electricity dual production plate is surrounded by the rectangular frame of the suction disc II at this time. By adopting this structure, after the suction disc II is moved to the position, the suction disc I can directly axially separate from the water and electricity dual production plate in the rectangular frame of the suction disc II, which avoids the generation of interference and also avoids the setting of a complex overturning structure and the like.

[0047] The conveying belt can realize the transportation of the adsorption assembly in the moisture absorption state, and also provides a moisture absorption occasion. In actual work, the conveying belt moves the water and electricity dual production plate falling from the conveying plate to the other side for storage and waiting for use.

[0048] As a preferred, it also includes a transmission member for transferring the moisture absorption assembly (or the water and electricity dual production plate) released from the suction disc I to the designated position of the conveying belt, and the transmission member includes:

[0049] A transmission vertical guide rail;

[0050] A driving sliding block slidingly arranged on the transmission vertical guide rail and capable of reciprocating movement;

[0051] A transmission plate installed on the driving slider for receiving the hygroscopic assembly released from the suction cup I, which can move vertically synchronously with the driving slider and can be controlled to flip over.

[0052] The transmission vertical guide rail is also provided with a transmission vertical driving motor matched with the driving slider for providing guidance and limiting for the driving slider moving above. Meanwhile, a rotary rudder is fixed on the driving slider, and the transmission plate is fixed on the rotary rudder. The transmission vertical driving motor can be used to realize the up-and-down movement of the driving slider, and the rotary rudder can be used to realize the rotation of the transmission plate to achieve controllable flipping.

[0053] The transmission plate can contain the water and electricity dual production plate released by the suction cup I above the transmission plate. The driving slider controls the up-and-down movement of the transmission plate and the rotation of the transmission plate. When the transmission plate moves to the lowest position, it controls the rotation of the transmission plate so that the water and electricity dual production plate slides onto the conveyor belt.

[0054] As a preferred, a box is further provided on the conveyor belt, and a box cover that can be opened and closed is selectively arranged on the box. The box is arranged on one hand to protect the transmission structure, and on the other hand to block sunlight from entering the inside, so that the hygroscopic assembly stored inside can reduce the evaporation of water vapor and can absorb water vapor at any time of the day.

[0055] The box cover is connected with the box shell, and can be opened and closed under the control of the electronic controller to close in sufficient sunlight to reduce the evaporation of water vapor of the hygroscopic assembly stored inside, and to open in less sunlight to allow the hygroscopic assembly to absorb water vapor in the air to increase the water content for easy use when working.

[0056] As a preferred, the adsorption type air water taking device is provided in plurality. The number of the adsorption type air water taking device can be set according to actual needs.

[0061] As a preferred, a water storage tank is further provided; part of the water collected by the water collecting tank is used for drip irrigation device for agricultural irrigation, and the excess water is stored in the water storage tank.

[0062] The drip irrigation device can adopt existing parts or self-designed parts. Generally, it is composed of a drip irrigation pipe with drip irrigation holes. In addition, a humidity sensor I for detecting soil humidity can be included, and irrigation of the drip irrigation device can be automatically controlled according to the sudden humidity signal.

[0063] According to needs, the application also includes a corresponding pipeline assembly, which includes a power supply line, a water supply line, a water delivery line and the like. The pipeline assembly includes a connection pipeline, a circuit pipeline or other pipelines such as a power supply line, a water supply line, a water delivery line and the like, which supply liquid water and electric energy to the drip irrigation device, and can also be connected to other equipment and supply liquid water and electric energy thereto.

The following examples will help those skilled in the art to further understand the application, but do not limit the application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the application. These are within the scope of the application.

[0081] As shown in Figure 1 and Figure 2 An automatic control adsorption type air water taking drip irrigation system, comprising: an adsorption type air water taking device 1, an automatic control transmission device 2; additionally comprising a controller 3, a storage battery 4, a water storage tank 5 and a drip irrigation device.

[0082] The main functions of the controller 3 are: (1) responsible for arranging the unstable voltage and current output by the solar photovoltaic panel, and outputting stable voltage and current; (2) responsible for processing and integrating the information of the internal sensors of the adsorption type air water taking device, and operating control; (3) responsible for processing important information of the automatic control of the overall system, and responsible for controlling the overall system. In actual use, the signal input end of the controller 3 is connected with each temperature sensor and humidity sensor; the signal output end of the controller 3 is connected with various drive mechanisms controlled by electrical signals, for issuing control signals. The controller generally adopts an electronic controller, which collects temperature signals and humidity signals at specific positions; obtains control signals according to the collected temperature signals and humidity signals.

[0083] The battery 4 is used to store the external input power, and is responsible for outputting stable voltage. The battery 4 is connected with the power input terminal and the power output terminal of the adsorption type air water taking device 1 through corresponding lines (power input line, power output line), and is used for inputting electrical signal and outputting electrical energy.

[0084] The water storage pool 5 is used to store the excess pure water produced by the system, and can be used as a water supply element for other water requiring components; in actual installation, the excess pure water in the water collecting tank is output through the water conveying line.

[0085] In the embodiment, the drip irrigation device can be an existing drip irrigation device, or a corresponding drip irrigation device can be set according to the need. The drip irrigation device generally includes a drip irrigation pipeline with a drip irrigation port, and a humidity sensor for detecting the water content of the soil where the plant is located can also be arranged. The electronic controller controls the drip irrigation device to drip irrigation for the plant according to the sensor signal.

[0086] As shown in Figure 3 , Figure 4 , Figure 5 The adsorption type air water taking device includes, from top to bottom, an upper top shell 101, a solar panel 102, a moisture absorbing assembly 103, a rectifier plate 104, a lower bottom shell 105, a condenser 106, a support seat 107 and a water collecting tank 108.

[0087] The upper top shell 101 is used to install and fixedly connect the photovoltaic panel (solar panel 102), and cooperates with the lower bottom shell 105. The upper top shell 101 is provided with a mounting groove for mounting an electromagnet I 109 around the bottom surface. The upper top shell 101 is provided with three terminal interfaces (a power input port I 101a, a signal output port I 1101b and a power output port I 101c) which can output input voltage and current and output sensor information. The upper top shell 101 is provided with a sealing protrusion 110 around the bottom surface which cooperates with a sealing groove 111 of the lower bottom shell 105 to form a sealing function to provide sealing for the device.

[0088] The solar panel 102 is provided with a cooperating voltage stabilizing assembly and the like. The solar panel 102 is used to generate electricity, and the generated electricity enters the upper top shell from the power line and is output to the battery from the terminal of the upper top shell. The solar panel 102 can select any existing solar photovoltaic panel. The solar panel can select various commercially available photovoltaic panels. The solar panel can not only provide electrical energy for the whole device through the power line, but also can provide electrical energy for other external devices through the power line. When the photovoltaic panel generates electricity under the sun, the unconverted light energy will be produced as waste heat, which can provide heat for the evaporation of water vapor in the moisture absorbing assembly fixed thereon, so that the water vapor is released, and the regeneration and desorption process of the moisture absorbing agent in the moisture absorbing assembly is realized.

[0089] The moisture absorption component 103 can use existing moisture absorption materials that can absorb water vapor and release water vapor when heated. As a feasible embodiment, the moisture absorption component 103 is composed of a porous matrix, a moisture absorption salt, and a coating film. The porous matrix uses active carbon fiber felt (ACFF), silica gel, zeolite, activated carbon, or activated alumina; the moisture absorption salt uses lithium chloride, calcium chloride, strontium chloride, lithium bromide, or strontium bromide; and the coating film uses a polytetrafluoroethylene (PTFE) film. During preparation, the porous matrix is first immersed in an aqueous solution of the moisture absorption salt, and after sufficient immersion, it is dried to obtain the moisture absorption material; then the moisture absorption material is wrapped and packaged with the coating film to obtain the moisture absorption component 103. In this embodiment, the porous matrix uses active carbon fiber felt, and the moisture absorption salt uses lithium chloride or calcium chloride.

[0090] The water absorption mechanism of the moisture absorption component 103 is as follows: the porous matrix can produce physical adsorption to adsorb water vapor; the moisture absorption salt can produce chemical adsorption to adsorb water vapor and generate hydrated salt. When the relative humidity exceeds the relative deliquescence humidity, the hydrated salt absorbs water vapor through deliquescence to generate a solution. When the solution reaches saturation, adsorption stops. The coating film has good air permeability, water resistance, and strong chemical stability. The entire matrix + moisture absorption salt is packaged in the coating film, and water vapor can pass through the film, but the solution cannot. Therefore, this film can prevent the leakage of salt solution and the absorption and evaporation of water vapor, thereby maintaining the cyclic adsorption capacity of the material.

[0091] The moisture absorption component 103 is also provided with a humidity sensor I for detecting the humidity thereof and a temperature sensor for detecting the temperature thereof. The humidity signal and the temperature signal of the humidity sensor I and the temperature sensor are transmitted to the controller through signal lines.

At the same time, the lower bottom shell 105 is also provided with a support and fixed mounting boss for the rectifier plate 104, for realizing the positioning of the rectifier plate 104. In addition, the top surface of the lower bottom shell 105 is also provided with a power input port II 105a (for powering the electrical appliances in the adsorption type air water taking device), a signal output port II 105b (for outputting sensor information), and a power output port III 105c (for outputting the electrical energy generated by the adsorption type air water taking device) corresponding to the power input port I 101a, the signal output port I 1101b, and the power output port I 101c of the upper top shell respectively; and two-by-two are conducted through the corresponding interfaces 114.

[0094] The lower bottom shell 105 is also provided with a temperature sensor II 115 for detecting the temperature thereof, and the temperature signal detected by the temperature sensor is transmitted to the controller 3 through a signal line; the controller simultaneously receives the humidity signal and the temperature signal of the humidity sensor I and the temperature sensor provided on the moisture absorbing assembly, and judges the water production efficiency of the moisture absorbing assembly according to the temperature difference of the moisture absorbing assembly, the temperature sensor of the lower bottom shell, and the humidity information of the humidity sensor I, and further judges whether the moisture absorbing assembly needs to be transported to the moisture absorbing working state.

[0095] The condenser 106 is a heat dissipation fin plate, which is fixed on the bottom of the lower bottom shell 105 by an adhesive. The rectifier plate is fixed inside the lower bottom shell 105 by a positioning boss and an adhesive, and an air gap is left between the two.

[0096] The support base 107 is a triangular plate structure with an inclined angle. For supporting the entire adsorption type air water taking device, the entire adsorption type air water taking device can be fixed on the support base by an adhesive or the like.

[0097] During installation, the moisture absorbing assembly 103 is directly adhered to the back of the solar panel 102 by using an adhesive with good heat conduction performance; then the solar panel 102 is fixed to the bottom surface of the upper top shell 101 by using an adhesive, and the three form an integrated structure, i.e. the water and electricity dual production plate 100 described below. The rectifier plate 104, the lower bottom shell 105, and the condenser are fixed integrally to form a lower fixing part. The upper top shell 101, the solar panel 102, the adsorption material 103, and the electromagnet pair constitute the water and electricity dual production plate 100 (refer to Figure 7 ) as a whole. When powered on, the water and electricity dual production plate is fixed on the lower fixing part by the adsorption effect of the electromagnet, and normal collection of solar energy and evaporation of water vapor for cold energy water collection are performed.

[0098] Refer to Figure 2The water collecting tank 108 comprises a tank body and a water collecting port arranged on the top of the tank body, which corresponds to the water outlet on the lower bottom shell 105 of the adsorption air water taking device, and collects the liquid water generated by cold energy. The bottom of the tank body is provided with a pipeline connected with the drip irrigation device, and the top is provided with a pipeline connected with the water storage pool, and the overflow water is stored by the water storage pool. The liquid water collected by the water collecting tank 108 is first supplied to the drip irrigation device, and the overflow pure water enters the water storage pool through the water conveying line and waits for subsequent use.

[0100] The parallel guide rails 201 are used to move the upper working suction cup I 202 and provide guidance, limiting and support. A driving motor (horizontal movement motor) and a corresponding transmission mechanism are arranged on the parallel guide rails 201 to drive the suction cup I 202 to move in a set direction. A guide groove is arranged on the parallel guide rails 201 to prevent the suction cup I 202 from falling off.

[0101] The suction cup I 202 is slidably arranged on the parallel guide rails and can reciprocally move. The suction cup I is used to attract and fix the moisture absorption assembly which needs to enter the moisture absorption working state and is transported to a set position of the conveyor belt. A corresponding electromagnet is arranged on the suction cup I 202, which can attract and release the water and electricity dual production plate with the same electromagnet by controlling the electromagnet.

[0102] The vertical guide rail 203 provides guidance and limiting for the suction cup II 204 and enables the suction cup II to move in the vertical direction. The vertical guide rail 203 is also provided with a driving motor and a corresponding driving motor to drive the suction cup II 204 to move in a set direction.

[0103] The suction cup II 204 is also provided with an electromagnet, which can attract and release the water and electricity dual production plate with the same electromagnet by controlling the electromagnet.

[0104] The conveyor belt 205 is used to move the water and electricity dual production plate dropped by the transmission plate to the other side for storage and waiting for use. The conveyor belt 205 is driven by a transmission motor.

[0105] The transmission vertical guide rail 206 is used to limit the driving slider 208 which moves above. The driving slider 208 is fixed with a rotary rudder 209 which is used to rotate the transmission plate 207. The transmission plate 207 is installed on the output end of the rotary rudder 209. The transmission vertical guide rail 206 is fixed with a driving motor (transmission vertical motor) which drives the driving slider 208 to move.

[0106] The transmission plate 207 is used to hold the water and electricity double production plate released by the suction cup I directly above the transmission plate. The transmission plate 207 is moved to the set position by the driving slider, and the rudder 209 is rotated to rotate the transmission plate 207, so that the water and electricity double production plate slides onto the conveyor belt.

[0107] The suction cup II is slidably arranged on the vertical guide rail and can reciprocate, and is used to suction and fix the moisture absorption assembly which needs to enter the evaporation working state and is transported to the set position of the adsorption type air water taking device; the suction cup II is a rectangular frame structure, the inner diameter size matches the outer diameter of the water and electricity double production plate, so that the water and electricity double production plate can be sleeved and suction fixed when suction.

[0108] The conveyor belt receives the moisture absorption assembly released by the suction cup I, and simultaneously transports the moisture absorption assembly which needs to enter the evaporation working state to the corresponding position of the suction cup II.

[0109] In actual work, the solar panel and the moisture absorption assembly are fixed and integrated into an integrated structure (i.e. called water and electricity double production plate), and the suction cup I and the suction cup II directly suction the water and electricity double production plate composed of the solar panel and the moisture absorption assembly to switch the working state of the moisture absorption assembly.

[0110] The suction cup I can suction and release the water and electricity double production plate which also has an electromagnet by controlling the electromagnet carried by the suction cup I. The parallel guide rail is used to move the upper working suction cup I and provide limiting, guiding and supporting.

[0111] The box body 208 is used to protect the transmission structure, and simultaneously blocks sunlight from entering the inside, so that the water and electricity double production plate stored inside can be reduced by temperature evaporation, and the water and electricity double production plate can absorb water vapor at any time of the day. The box cover plate 210 is arranged on the box body 208, and the box cover plate 210 is connected with the box shell and can be opened and closed by the electronic controller 3 to close in sufficient sunlight to reduce the water vapor evaporation of the water and electricity double production plate stored inside, and to open in less sunlight to make the water and electricity double production plate 100 absorb water vapor in the air to increase the water content for use in work.

[0112] The automatic control transmission system is mainly used to transfer and store the water and electricity double production plate on the upper layer of the adsorption type air water taking device, can be used to improve the water production efficiency of the whole work, can store the water and electricity double production plate of the adsorption type air water taking device, and can make the idle water and electricity double production plate absorb water.

[0113] In actual use, the solar panel is irradiated by sunlight, and the solar panel converts solar energy into electric energy to supply power to the device and external equipment through the power supply line. At the same time, the solar panel is heated by light and generates heat as a heat source. The hygroscopic assembly close to the solar panel will be heated to discharge the absorbed water in the form of water vapor. The water vapor reaches the cavity between the rectifier plate and the lower bottom plate of the lower bottom shell after passing through the rectifier plate which reduces the convection effect, and finally condenses on the lower bottom plate of the lower bottom shell. The liquid water is finally discharged through the water guide line, and the water collecting tank collects the generated liquid water.

[0114] When the controller detects that the working efficiency of the hygroscopic assembly in a certain adsorption type air water taking device is lower than the set value, the automatic control transmission system is started, the suction cup I moves above the adsorption type air water taking device, the controller controls the electromagnetic signal of the electromagnet, so that the water and electricity dual production plate of the corresponding adsorption type air water taking device is separated from the structure of the bottom, and is fixed by the suction cup I at the same time. The suction cup I moves the water and electricity dual production plate to the corresponding position of the transmission plate, releases the water and electricity dual production plate on the transmission plate, and moves the transmission plate to a set height, flips, and moves the water and electricity dual production plate to the transmission belt. At the same time, the conveying belt moves the water and electricity dual production plate after the completion of the hygroscopic to the corresponding position of the suction cup II, and lowers the suction cup II to the position where it can be attracted from the side. At this time, the water and electricity dual production plate is sleeved in the middle of the suction cup II, is electrified and attracted, and the water and electricity dual production plate meeting the hygroscopic requirement is transported to a specific position. At this time, the suction cup I is electrified to extract the water and electricity dual production plate in the suction cup II axially, and moves to a set position to realize the installation of new water and electricity dual production plate.

[0115] In order to meet the suction requirement of the suction cup II, an electromagnet or metal that can be attracted by the electromagnet can be arranged on one side or both sides of the upper top shell, or an electromagnet coil for lateral attraction can be directly arranged in the water and electricity dual production plate, which can realize the function of lateral attraction.

[0116] In the hygroscopic working state of the hygroscopic assembly, the hygroscopic agent in the hygroscopic assembly absorbs water vapor in the air and stores it. Under a certain environmental relative humidity, when the water vapor passes through the hygroscopic agent, the water vapor will be absorbed by the hygroscopic agent through the coating film until it is saturated.

[0117] When drip irrigation is needed, the liquid water is collected into the drip irrigation device through the water guide line 6, and the electric energy is supplied to the drip irrigation device through the power supply line. By changing the control parameters of the drip irrigation device, the water is finally transported to the plant through the water delivery line to complete the function of drip irrigation.

It should be understood that the present application is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essential content of the present application.
