Technical Field

[0002] Desert surface water harvesting devices are used to collect surface moisture in desert areas. Currently, very few effective devices exist for surface water harvesting in desert regions. Generally, deep pits or drills are used to extract groundwater with pumps, typically powered by electricity, consuming significant electrical energy. Furthermore, the deep extraction depth is detrimental to maintaining groundwater levels, and the equipment is expensive. These methods are unsuitable for field conditions without power, are not energy-efficient, and the systems are complex and costly. Only a few extremely rare desert surface water harvesting devices can collect surface moisture in desert areas, but their efficiency is extremely low. Summary of the Invention

It includes a surface water collection unit 1, a wind-powered pump suction lifting unit 2, a water storage device 3, and an airborne water vapor interception unit 4. The wind-powered pump suction lifting unit 2 includes a lifting pump 201, a cam mechanism 202, a sail mechanism 203, and a fixed pile 204. The sail mechanism 203, the cam mechanism 202, and the lifting pump 201 are connected to the fixed pile 204. The inlet end of the lifting pump 201 is connected to the surface water collection unit 1, and the outlet end of the lifting pump 201 is connected to the water storage device 3.

[0021] The above-ground water collection unit 1 includes multiple water storage and suction units 101, water storage and suction unit branch pipes 102, capillary siphon lifting units 103, intermediate water storage and suction units 104, and connecting pipes 106. The multiple water storage and suction units 101 are connected to the lower ends of the capillary siphon lifting units 103 via the water storage and suction unit branch pipes 102. The multiple water storage and suction units 101 are horizontally arranged close to the ground. The capillary siphon lifting units 103 are installed at an angle to the ground. The upper end of the capillary siphon lifting units 103 is connected to the inlet end of the intermediate water storage and suction units 104 via connecting pipes 106. The outlet end of the intermediate water storage and suction units 104 is connected to the inlet end of the lifting pump 201 via connecting pipes 106. Anti-evaporation sleeves 105 are fitted to the outer surfaces of the capillary siphon lifting units 103 and the intermediate water storage and suction units 104. The anti-evaporation sleeve 105 is made of sunshade and heat insulation material to prevent the evaporation of water in the capillary siphon lifting unit 103 and the relay water storage and absorption unit 104; the connecting pipes 106 of the ground water collection unit 1 and the branch pipes 102 of the water storage and absorption unit are filled with water storage and absorption medium for the absorption, storage and transfer of water vapor.

[0022] like Figure 3 As shown, the water storage and absorption unit 101 comprises a water storage and absorption unit shell 101a, a water storage and absorption unit water storage and absorption medium 101b, and a water storage and absorption unit plug 101c. The water storage and absorption unit shell 101a has a hollow structure and has an array of through holes on its outer surface. The water storage and absorption unit water storage and absorption medium 101b is installed inside. The water storage and absorption unit plug 101c is installed at the outlet end of the water storage and absorption unit shell 101a and is connected to the capillary siphon lifting unit 103 through the water storage and absorption unit branch pipe 102.

[0023] The capillary siphon lifting unit 103 is a tubular structure, including a siphon unit shell 103a, a capillary bundle 103b, a water-absorbing sponge 103c, and a siphon unit plug 103d. The siphon unit shell 103a is a hollow tubular structure, with the capillary bundle 103b installed inside. The capillary bundle 103b has water-absorbing sponges 103c at both ends for anti-clogging protection. The siphon unit shell 103a has siphon unit plugs 103d at both ends. One end of the siphon unit plug 103d is connected to the water storage and absorption unit 101 through a branch pipe 102 of the water storage and absorption unit, and the other end is connected to the relay water storage and absorption unit 104 through a connecting pipe 106.

[0024] The relay water storage and absorption unit 104 consists of a relay water storage and absorption unit shell 104a, a relay water storage and absorption unit water storage medium 104b, and a relay water storage and absorption unit plug 104c. The relay water storage and absorption unit shell 104a is a hollow structure, and the relay water storage and absorption unit water storage medium 104b is installed inside. The relay water storage and absorption unit plug 104c is installed at both ends of the relay water storage and absorption unit shell 104a. The two ends of the relay water storage and absorption unit plug 104c are respectively connected to the capillary siphon lifting unit 103 and the inlet end of the lifting pump 201 through connecting pipes 106.

[0025] The working principle of the ground-level water collection unit 1 is as follows: Multiple water storage and absorption units 101 of the ground-level water collection unit 1 are placed close to the ground. These units absorb and store moisture from the ground and air. Then, the capillary siphon lifting unit 103 lifts the moisture from bottom to top into the intermediate water storage and absorption unit 104 via capillary siphon action. The intermediate water storage and absorption unit 104 serves as a water storage and absorption unit, and the water stored in it is supplied to the lifting pump 201, which then draws, pumps, and lifts the water into the water storage device 3. The negative pressure generated by the lifting pump 201 also draws, transports, and lifts the moisture inside the ground-level water collection unit 1, increasing its water absorption, transport, and lifting efficiency. Each connecting pipe 106 inside the ground-level water collection unit 1 contains a water-absorbing medium for moisture absorption and transfer.

[0026] The airborne water vapor interception unit 4 includes an airborne water vapor interception net array 401 and airborne water vapor interception net array fixing stakes 402; the airborne water vapor interception net array 401 is an array composed of a three-dimensional perforated net; the airborne water vapor interception net array 401 is fixed to the ground by the airborne water vapor interception net array fixing stakes 402.

[0027] The airborne water vapor interception unit 4 is fixed to the ground by the airborne water vapor interception net array fixing pile 402, and the airborne water vapor interception net array 401 is fixed directly above the multiple water storage and absorption units 101. When water mist and water vapor come into contact with the airborne water vapor interception net array 401 during the day and night, they will be condensed and intercepted on the net, and then flow downward due to gravity, collecting on the multiple water storage and absorption units 101, thereby enhancing the water storage and absorption efficiency of the multiple water storage and absorption units 101, that is, enhancing the water collection efficiency and capacity of the entire system.

[0028] like Figure 4 As shown, the booster pump 201 includes a pump body 2011, an inlet pipe 2012, an outlet pipe 2013, a pump body upper cover 2014, a pump body lower cover 2016, a piston assembly 2017, an inlet check valve 2018, and an outlet check valve 2019. The pump body 2011 is generally a hollow cylinder, with its upper outer cylindrical surface communicating with the inlet pipe 2012 and its middle outer cylindrical surface communicating with the outlet pipe 2013. The inlet check valve 2018 is located inside the inlet pipe 2012, and the outlet check valve 2019 is located inside the outlet pipe 2013. A piston assembly 2017 is installed, which consists of a piston rod 2017a and a piston 2017b. The piston 2017b is slidably connected to the inner wall of the pump body 2011. A pump body cover 2014 is sealed and fitted at the upper end of the pump body 2011. The inner hole of the pump body cover 2014 is slidably fitted to the upper end of the piston rod 2017a through a cover sealing ring 2015. A pump body lower cover 2016 is sealed and fitted at the lower end of the pump body 2011. The inner hole of the pump body lower cover 2016 is coaxially fitted with a lower cover guide sleeve 2016a. The lower cover guide sleeve 2016a is slidably fitted to the lower end of the piston rod 2017a.

[0029] The inlet check valve 2018 consists of an inlet check valve plug 2018a and an inlet check valve diaphragm 2018b, which are coaxially stacked inside the inlet interface pipe 2012. The inlet check valve plug 2018a is a rigid structure with a through hole, installed on the outside and the inlet check valve diaphragm 2018b on the inside. Fluid in the inlet interface pipe 2012 flows from the outside to the inside and does not flow out. The outlet check valve 2019 consists of an outlet check valve plug 2019a and an outlet check valve diaphragm 2019b, which are coaxially stacked inside the outlet interface pipe 2013. The outlet check valve plug 2019a is a rigid structure with a through hole, installed on the inside and the outlet check valve diaphragm 2019b on the outside. Fluid in the outlet interface pipe flows from the inside to the outside and does not flow in.

[0030] like Figure 5As shown, the cam mechanism 202 includes a cam mechanism fixing frame 2021, a cam 2022, a slide rod 2023, a lever 2024, and a sliding sleeve 2025. The cam mechanism fixing frame 2021 has a double-arm structure, with a cam mechanism fixing frame clamp 2021a at the right end of the double arms. The cam mechanism fixing frame clamp 2021a is detachably fixed to the fixing post 204. A coaxial through hole is provided in the middle of the double arms, through which the cam 2022 is installed coaxially via an oilless bearing. A coaxial through hole is provided at the left end of the double arms, through which the slide rod 2023 is slidably installed via the sliding sleeve 2025. 2022 is a cylindrical cam, and the outer cylindrical surface of the cam 2022 is provided with a cam groove 2022a, which is a closed annular groove; the slide rod 2023 is a cylindrical rod, and the outer circular surface of the slide rod 2023 is provided with an axial sliding groove 2023a. The inner wall of the sliding sleeve 2025 is provided with a protruding key 2025a, which is fitted in the sliding groove 2023a to limit the circumferential movement of the slide rod 2023; the lever 2024 is fixedly fitted on the slide rod 2023, and the side of the lever 2024 is provided with a protruding tongue 2024a, which slides in conjunction with the cam groove 2022a.

[0031] The sail mechanism 203 consists of a sail fixing frame 2031, a sail shaft 2032, and a sail 2033. The sail fixing frame 2031 is a double-arm structure with upper and lower arms. The right end of the double arms is equipped with a clamp structure, which can be detachably and fixedly installed with the fixing post 204. The middle of the double arms is provided with a coaxial through hole, in which the sail shaft 2032 is rotatably installed through an oil-free bearing. The sail shaft 2032 is cylindrical and rod-shaped, with the sail 2033 fixedly installed at the top. The lower end of the sail shaft 2032 is connected to the input end of the cam mechanism 202. The sail 2033 is composed of several blades with an arc-shaped cross section.

[0032] The working principle of the wind power pump lifting unit 2 is as follows: Wind blows the sail 2033 to rotate. The sail 2033 drives the cam 2022 to rotate via the sail shaft 2032. The cam 2022 drives the slide rod 2023 to move up and down reciprocally via the lever 2024. The groove 2023a on the outer surface of the slide rod 2023 is engaged with the protruding key 2025a on the inner wall of the sliding sleeve 2025. The sliding sleeve 2025 is fixedly installed on the cam mechanism mounting bracket 2021. This installation method allows the slide rod 2023 to move up and down, but not rotate. The slide rod 2023 is fixedly connected to the piston rod 2017a of the lifting pump 201, driving the piston rod 2017a to move up and down, which in turn drives the piston 2017b to move up and down. The piston 2017b divides the pump body 2011 into a non-connected upper chamber and a lower chamber. The lower chamber of the pump body 2011 is connected to the external air pressure. The 2018 inlet check valve only allows fluid to flow from the outside to the inside, and not from the inside to the outside. The 2019 outlet check valve only allows fluid to flow from the inside to the outside, and not from the outside to the inside.

[0033] When piston 2017b moves downward, a negative pressure is generated in the upper chamber of pump body 2011, opening the inlet check valve 2018 and closing the outlet check valve 2019. Fluid is drawn into the upper chamber of pump body 2011 from the inlet pipe due to the negative pressure difference between atmospheric pressure outside the inlet pipe 2012 and the upper chamber of pump body 2011. When piston 2017b moves upward, a positive pressure is generated in the upper chamber of pump body 2011, closing the inlet check valve 2018 and opening the outlet check valve 2019. Fluid is forced out of the upper chamber of pump body 2011 from the outlet pipe due to the positive pressure difference between atmospheric pressure outside the outlet pipe 2013 and the upper chamber of pump body 2011. Under the action of wind power, the wind-powered pumping unit realizes the continuous suction and pumping flow of fluid from inlet pipe 2012 to outlet pipe 2013.

[0034] The power for the absorption and transport of water inside the ground water collection unit 1 comes partly from the humidity gradient and free diffusion of water inside the ground water collection unit 1, the capillary siphon effect of the water storage and absorption medium pores, and the capillary siphon effect of the capillary bundle, and partly from the suction and pumping action of the lift pump 201. Through the combined action of the two, the water collection efficiency is improved.
