[0031] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0032] like Figure 1As shown, the present invention provides a desert water collection and irrigation device 100 based on the thermoelectric cooling principle, including a box body 1, a wind collection mechanism 2 telescopically installed in the box body 1, a condensing mechanism 3, a water storage mechanism 4 connected to the bottom of the box body 1, an irrigation mechanism 5 connected to the water storage mechanism 4, and a power supply mechanism 6.

[0033] Specifically, the box body 1 is cylindrical, and a cylindrical cavity is formed inside the box body 1. The box body 1 includes a shell 11 and a shell cover 12 arranged on the top of the shell 11. The shell 11 is cylindrical, and the inside of the shell 11 is used to place the wind collecting mechanism 2. Figure 2 As shown, the shell cover 12 is a circular shell cover that is compatible with the top of the outer shell 11. The shell cover 12 adopts a rotary opening and closing type. The shell cover 12 includes an annular mounting plate 121 and an opening and closing blade 122 fixed on the annular mounting plate 121. The mounting plate 121 is in the shape of a circular ring, and the outer side of the mounting plate 121 is directly compatible with the inner diameter of the top of the outer shell 11. A plurality of mounting grooves 1211 are provided on the mounting plate 121. The mounting grooves 144 are arc-shaped, and the plurality of mounting grooves 1211 are evenly arranged circumferentially. The arc-shaped mounting grooves 1211 extend radially as a whole on the annular mounting plate 121. The number of opening and closing blades 122 is equal to the number of mounting grooves 1211. The opening and closing blades 122 are distributed in a circular ring and are connected to the lower end surface of the mounting plate 12. The opening and closing blades 122 are in the shape of an oblique triangle, and the top of the opening and closing blades 122 is pointed. An electromagnetic column 1221 is provided at the tail end of the opening and closing blade 122 . The electromagnetic column 1221 is suitable for being installed in the installation groove 1211 . The locking blade 122 is driven and connected by a driving member and controlled by a controller, thereby realizing the rotation opening and closing of the shell cover 12 .

[0034] Specifically, the air collection mechanism 2 is telescopically mounted within the housing 1. It comprises a telescopic rod 21, a drive shaft 22 mounted on top of the telescopic rod 21, a wind drive assembly 23 secured above the drive shaft 22, an air inducing member 24, and a filter assembly 25 secured to the telescopic rod 21. The telescopic rod 21 is vertically mounted in the center of the housing 1 and comprises a first rod 211, a second rod 212 sleeved around the outside of the first rod 211, and a third rod 213 sleeved around the outside of the second rod 212. The telescopic rod 21 is connected to a drive member, which is in turn connected to the power supply mechanism 6, thereby controlling the telescopic movement of the telescopic rod 21. When the telescopic rod 21 extends upward, the first rod 211 is located at the bottom of the housing 1, and the third rod 213 extends to the top of the housing 1. When the telescopic rod 21 retracts downward, the third rod 213 fits over the outside of the second rod 212, which in turn fits over the outside of the first rod 211, placing the entire telescopic rod 21 at the bottom of the housing 1. The transmission shaft 22 is rotatably secured to the top of the third rod 213 via bearings or the like. A wind drive assembly 23 is secured above the transmission shaft 22 and includes a mounting member 231 and blades 232 symmetrically arranged on either side of the mounting member 231. The mounting member 231 is secured to the transmission shaft 22 and is used to mount and fix the blades 232. The diameter of the blades 232 is smaller than the diameter of the top opening of the housing 1. The blades 232 are made of nylon fiber. The blades 232 are symmetrically designed on both sides. The outer curves of the blades 232 are gourd-shaped. An opening is provided in the center of the two blades 232 to reduce the resistance of the wind flowing through the blades, thereby reducing the starting wind speed. The connection area between the blades 232 and the transmission shaft 22 is smaller, and the required rotation of the mounting member 231 is shorter, making the entire device easier to be driven by the wind. The draft member 24 is fixed to the lower end of the transmission shaft 22. The draft member 24 is driven by the wind to rotate the blades 232 and the transmission shaft 22. Since the draft member 24 is fixed to the lower end of the transmission shaft 22, the draft member 24 rotates under the drive of the transmission shaft 22. In some embodiments, the draft member 24 can be a reverse fan, thereby sucking the external air containing water vapor into the interior of the housing 1. When the telescopic rod 21 is extended upward, the third rod 213 extends to the top of the housing 1. At this time, the transmission shaft 22 located above the third rod 213 and the wind-driven assembly 23 mounted on the transmission shaft 22 extend to a position above the top of the housing 1. When the wind-collecting mechanism 2 is no longer needed, the telescopic rod 21 can be controlled to retract downward to retract the transmission shaft 22, the wind-driven assembly 23 fixed above the transmission shaft 22, and the air-inducing member 24 into the interior of the housing 1. The housing cover 12 can then be controlled to rotate and close, thereby preserving the wind-driven assembly 23 and the air-inducing member 24 and extending their service life.

[0035] like Figure 3 、 Figure 4As shown, the filter assembly 25 is positioned above the third rod 213 of the telescopic rod 21. When the telescopic rod 21 is extended upward, the filter assembly 25 is positioned at the upper end of the interior of the housing 1, filtering the external air. The filter assembly 25 comprises a filter 251, a retractable frame 252, and a slider 253. When deployed, the filter 251 fits snugly within the interior of the housing 1. The filter 251 is secured to the retractable frame 252, which has an umbrella-like structure. The support frame of the retractable frame 252 is connected to the slider 213. The slider 253 is installed on the outer surface of the third rod body 213. The material of the slider 253 is made of iron or other materials that are easy to electromagnetically attract. In some embodiments, an electromagnetic coil (not shown in the figure) is provided around the upper position of the inner side surface of the third rod body 213. When the slider 253 needs to move up, the electromagnetic coil is energized by the controller and the power is supplied. The slider 253 moves up, and the retractable frame 252 is stretched. When the slider 253 needs to move down, the electromagnetic coil is disconnected by the controller, and the slider 253 moves downward under the action of gravity, thereby realizing the up and down movement of the slider 253 on the outer side surface of the third rod body 213. When the slider 213 moves upward, the contraction skeleton 252 stretches upward, and the filter screen 251 is stretched out. At this time, the filter screen 251 is tightly fitted with the inner wall of the box body 1; when the slider 213 moves downward, the contraction skeleton 252 contracts inward. At this time, the filter screen 251 fixed on the contraction skeleton 252 contracts inward, and there is a gap between the outer side of the filter screen 251 and the inside of the box body 1, which facilitates the downward contraction of the telescopic rod 21.

[0036] In some embodiments, the condensing mechanism 3 is mounted on the outer surface of the box body 1, and the condensing mechanism 3 uses a flexible thermoelectric refrigeration sheet for cooling. The cooling principle is as follows: Figure 8 As shown, the thermoelectric cooling sheet utilizes a PN junction composed of specialized semiconductor materials to form a thermocouple pair, which generates cooling through direct current. The thermoelectric cooling sheet does not require a refrigerant. The flexible thermoelectric cooling sheet cools the interior walls of the enclosure 1, while heat is dissipated through fins on the exterior. This allows air containing water vapor to enter the enclosure 1 and, upon encountering the cooler interior walls, condense into water droplets, which then gather at the bottom of the enclosure 1.

[0037] In some embodiments, the box body 1, the air collecting mechanism 2 and the condensing mechanism 3 may be provided in two or more groups to increase the water collection capacity.

[0038] Specifically, the water storage mechanism 4 is connected to the bottom of the housing 1 and includes a water tank 41, a water inlet pipe 42 connected to the water tank 41, and a water level sensor 43 disposed within the water tank 41. The water tank 41 can be disposed in sandy soil to reduce evaporation of water in the water tank 41. The water inlet pipe 42 is connected to the bottom of the housing 1, allowing water condensed by the condensing mechanism 3 and collected at the bottom of the housing 1 to enter the water tank 41 through the water inlet pipe 42 for storage. The water level sensor 43 is disposed within the water tank 41. When the water level sensor 43 detects that the water in the water tank 41 is about to be filled, it sends a signal to the controller, thereby controlling the air collection mechanism 2 and the condensing mechanism 3 to stop operating.

[0039] Specifically, the irrigation mechanism 5 is connected to the water storage mechanism 4 and draws water from the water tank 41 to achieve irrigation. The irrigation mechanism 5 includes a first telescopic tube 51, a second telescopic tube 52 connected to the first telescopic tube 51, a nozzle 53, and a water pump 54. The first telescopic tube 51 is mounted vertically, with its bottom end connected to the bottom of the water tank 4, for pumping water from the interior of the water tank 4. The second telescopic tube 52 is positioned perpendicular to the first telescopic tube 51, positioned horizontally and connected to the top of the first telescopic tube 51. Two, or more, second telescopic tubes 52 are provided. The number of nozzles 53 is the same as the number of second telescopic tubes 52, and they are mounted at the ends of the second telescopic tube 52. The water pump 54 is connected to the first telescopic tube 51. The water from the water tank 4 is drawn by the water pump 54 into the first and second telescopic tubes 51, 52, and finally discharged from the nozzle 53, achieving irrigation. By providing the first telescopic tube 51 and the second telescopic tube 52 , the height and width of irrigation can be adjusted to increase the irrigation area.

[0040] like Figure 5 、 Figure 6 As shown, specifically, the power supply mechanism 6 includes a photovoltaic panel 61, an extension component 62 connected to the photovoltaic panel 61, and a power supply component 63 arranged at the bottom of the photovoltaic panel 61. There are multiple photovoltaic panels 61, and the photovoltaic panels 61 are in a triangular structure. The multiple photovoltaic panels 61 are arranged in a circle to receive solar energy. The extension component 62 includes an electromagnetic column 621, a sliding sleeve 622 sleeved on the electromagnetic column 621, a connecting rod 623 and an adjustment member 624 arranged at the end of the photovoltaic panel 61. The electromagnetic column 621 is a vertically fixed circular cylinder. The sliding sleeve 622 is sleeved on the outer surface of the electromagnetic column 621. The material of the sliding sleeve 622 is made of steel or other materials that are convenient for electromagnetic attraction, such as Figure 7As shown, in some embodiments, multiple electromagnetic modules 6211 are evenly distributed within the electromagnetic column 621. When the sliding sleeve 622 needs to move upward, the controller controls the electromagnetic modules 6211 to be powered sequentially from bottom to top, and then shuts off the power to the lower electromagnetic module 6211, thereby attracting the sliding sleeve 622 to move upward. When the sliding sleeve 622 needs to move downward, the controller controls the electromagnetic modules 6211 to be powered off, and the sliding sleeve 622 moves downward under the action of gravity, thereby achieving the up and down movement of the sliding sleeve 622 on the outer side of the electromagnetic column 621. Multiple connecting rods 623 are provided, and adjacent connecting rods 623 have different lengths. The number of connecting rods 623 is equal to the number of photovoltaic panels 61. One end of the connecting rod 623 is rotatably connected to the sliding sleeve 622 via a hinge, and the other end of the connecting rod 623 is rotatably connected to the center of the photovoltaic panel 61 via a hinge. The adjustment member 624 includes a mounting ring 6241 and a rotating ring piece 6242 that fits over the outer surface of the mounting ring 6241. The mounting ring 6241 is annular in shape, with a circular vertical cross-section. The mounting ring 6241 is fixed to the bottom of the connecting rod 623. A plurality of rotating ring pieces 6242 fit over the outer surface of the mounting ring 6241. The number of rotating ring pieces 6242 is equal to the number of photovoltaic panels 61. The ends of the photovoltaic panels 61 are connected to the rotating ring pieces 6242. When the photovoltaic panels 61 extend and retract, the rotating ring pieces 6242 can be positioned on the mounting ring 6241 and rotate with the photovoltaic panels 62. The power supply 63 is located below the photovoltaic panels 61 and is electrically connected to the panels 61. The power supply 63 includes a battery housed within a power supply box for storing electrical energy converted by the photovoltaic panels 61. The power supply 63 is used to power electrical devices. By providing an extendable and retractable power supply mechanism 6 , the photovoltaic panel 61 can be retracted according to weather conditions, thereby reducing damage to the photovoltaic panel 61 .

[0041] The desert water collection and irrigation device 100 based on the thermoelectric cooling principle of the present invention is suitable for condensation water production when the temperature is low at night, the wind speed in the desert area and the water content in the air are high. At this time, the shell cover 12 on the top of the box body 1 is controlled by the controller to rotate and open, and then the telescopic rod 21 is controlled to extend upward, and the wind drive component 23 rises to the upper position of the box body 1 for inducing wind. At this time, the wind inducing member 24 is located at the top position of the box body 1. Since the wind inducing member 24 is a reverse fan, the slider 253 is then controlled to move upward, so that the contraction skeleton 252 extends upward. At this time, the filter screen 251 is opened, and the filter screen 251 is tightly fitted with the inner wall of the box body 1. The reverse fan draws the external air containing water vapor into the box body. The inside of the box 1 is filtered out of sand and dust in the air through the filter 251; then the condensing mechanism 3 is started, and the inner wall of the box 1 is cooled by the flexible thermoelectric cooling sheet, so that the air with water vapor entering the inside of the box 1 condenses into water droplets when encountering the inner wall of the box 1 with a lower temperature, and then gathers at the bottom of the box 1, and enters the water storage tank 41 through the water inlet pipe 42. When the water level of the water storage tank 41 reaches a critical value, the wind collecting mechanism 2 and the condensing mechanism 3 are closed. At this time, the controller controls the telescopic rod 21 to retract, and the wind drive component 23 and the air inducing member 24 are stored in the interior of the box 1, and then controls the rotation and closure of the shell cover 12 to reduce the damage caused by long-term wind erosion of sand and dust. When the light intensity is high during the day, the controller sends a command to drive the sliding sleeve 622 downward to open the multiple photovoltaic panels 61 to receive solar energy and convert it into electrical energy and store it in the power supply unit 63 to power electrical equipment. At night when there is no light, the sliding sleeve 622 is controlled to move upward. At this time, the multiple connecting rods 623 are retracted and the photovoltaic panels 61 are closed upward, reducing the force area of ​​the photovoltaic panels 61 under wind blowing. It can also reduce the damage to the photovoltaic panels 61 caused by wind sand and dust and prevent wind sand from accumulating on the surface of the photovoltaic panels 61, thereby extending the service life of the photovoltaic panels 61 and improving the conversion efficiency of the photovoltaic panels 61.

[0042] The desert water collection and irrigation device 100 based on the thermoelectric cooling principle of the present invention is provided with a telescopic rod 21. When the wind collecting mechanism 2 does not need to work, the telescopic rod 21 can be controlled to retract downward to store the transmission shaft 22, the wind drive component 23 fixed above the transmission shaft 22, and the air inducing member 24 into the interior of the box body 1. Then the shell cover 12 is controlled to rotate and close, so as to preserve the wind drive component 23 and the air inducing member 24 and extend the service life of the wind drive component 23 and the air inducing member 24; a retractable frame 252 and a slider 253 are provided on the filter component 25. When the slider 213 moves upward, the retractable frame 252 extends upward. At this time, the filter screen 251 is stretched open, and the filter screen 251 is tightly fitted with the inner wall of the box body 1; when the slider 213 moves downward, the retractable frame 252 retracts inward. At this time, the filter screen 251 fixed on the retractable frame 252 retracts inward. When the photovoltaic panel 62 is extended or retracted, the rotating plate 6242 can be located on the mounting ring 6241 to rotate with the photovoltaic panel 62, and the sliding sleeve 622 can be controlled to move up and down. At this time, multiple connecting rods 623 are retracted or unfolded. When the photovoltaic panel 61 is not needed, the photovoltaic panel 61 is closed upward, reducing the force area of ​​the photovoltaic panel 61 under wind blowing, and also reducing the damage of wind sand and dust to the photovoltaic panel 61 and preventing wind sand from accumulating on the surface of the photovoltaic panel 61, thereby extending the service life of the photovoltaic panel 61 and improving the conversion efficiency of the photovoltaic panel 61.
