[0016] like Figures 1 to 3 As shown, a high-efficiency desert surface water collection device is used for the collection, transportation, and lifting of moisture from the ground and air in desert areas. It consists of a surface water collection unit 1, a water storage device 2, and an airborne water vapor interception unit 3. The surface water collection unit 1 includes multiple water storage and absorption units 101, water storage and absorption unit branch pipes 102, a capillary siphon lifting unit 103, a relay water storage and absorption unit 104, and a connecting pipe 106. The multiple water storage and absorption units 101 are connected to the lower ends of the capillary siphon lifting unit 103 via the water storage and absorption unit branch pipes 102. The multiple water storage and absorption units 101 are horizontally arranged close to the ground. The capillary siphon lifting unit 103 is installed at an angle to the ground. The upper end of the capillary siphon lifting unit 103 is connected to the inlet end of the relay water storage and absorption unit 104 via the connecting pipe 106. The outlet end of the relay water storage and absorption unit 104 is connected to the water storage device 2 via the connecting pipe 106. The airborne water vapor interception unit 3 is located directly above the multiple water storage and absorption units 101.
[0017] The water storage and absorption unit 101 includes a water storage and absorption unit shell 101a, a water storage and absorption unit 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 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.
[0018] 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 branch pipe 102 of the water storage and absorption unit, and the other end of the siphon unit plug 103d is connected to the relay water storage and absorption unit 104 through the connecting pipe 106.
[0019] 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 has 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.

[0020] Multiple water storage and absorption units 101 of the above-ground water collection unit 1 are placed close to the ground. These units absorb and store moisture from the ground and air. Then, a capillary siphon lifting unit 103 uses capillary action to lift the moisture from bottom to top into a relay water storage and absorption unit 104. The relay water storage and absorption unit 104 serves as a water storage and absorption unit, and the water stored there is transferred and stored in the water storage device 2 via connecting pipes 106. Each section of the connecting pipe 106 inside the above-ground water collection unit 1 contains a water-absorbing medium for moisture absorption and transfer.
[0021] The airborne water vapor interception unit 3 includes an airborne water vapor interception net array 301 and airborne water vapor interception net array fixing piles 302. The airborne water vapor interception net array 301 is an array composed of a three-dimensional perforated net. The airborne water vapor interception net array 301 is fixed to the ground by the airborne water vapor interception net array fixing piles 302. The airborne water vapor interception net array 301 is fixed directly above multiple water storage and absorption units 101. After the intercepted water vapor condenses and converges, it flows downwards and converges on the multiple water storage and absorption units 101 due to gravity, thereby enhancing the water storage and absorption efficiency of the multiple water storage and absorption units 101.
[0022] The airborne water vapor interception unit 3 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 capacity, output and efficiency of the entire system.
[0023] The outer surfaces of the capillary siphon lifting unit 103 and the relay water storage and absorption unit 104 are fitted with anti-evaporation sleeves 105, which are made of sunshade and heat insulation material.
[0024] The water storage device 2 consists of a housing 201 and a water storage and absorption medium 202. The housing 201 is hollow, and the water storage and absorption medium 202 is installed inside. The water storage and absorption medium 202 is a substance with water storage and absorption functions. The housing 201 has a connection port on its exterior, which is connected to a relay water storage and absorption unit 104 via a connecting pipe 106. The housing 201 has a water distribution hole 2011 on its upper part. The water distribution hole 2011 is a through hole used to disperse water vapor in the water storage and absorption medium 202. The dispersed water can be used to supply water to the roots of plants in desert areas. The water distribution hole 2011 on the upper part of the water storage device 2 is used to disperse water vapor in the water storage and absorption medium 202.
[0025] The moisture content decreases from multiple water storage and absorption units 101 to the water storage device 2. Through the free diffusion of water, the capillary effect of the water storage and absorption medium inside the ground water collection unit 1, the transmission function, and the capillary effect of the capillary siphon lifting unit 103, the collected water vapor is continuously gathered into the water storage device 2.
[0026] The water storage device 2 can be adapted to multiple above-ground water collection units 1 to enhance the water collection capacity.
[0027] The inner cavity of the branch pipe 102 and connecting pipe 106 of the water storage and absorption unit is filled with a water storage and absorption medium for the storage and transfer of water vapor.
