Description

Technical Field

[0001] This invention relates to a desert underground water collection device with pump suction function, belonging to the technical field of desert underground water collection devices. Background Technology

[0002] Desert groundwater collection devices are used to collect groundwater near the surface in desert areas. Currently, very few effective devices exist for collecting groundwater near the surface in desert regions. Generally, deep pits or drills are used to extract groundwater with pumps, typically electrically powered, consuming electricity. The deep extraction depth is detrimental to maintaining groundwater levels, and the equipment is expensive. It is unsuitable for field conditions without power, is not energy-efficient, and the system is complex and costly. Only a few extremely rare desert groundwater collection devices can collect groundwater near the surface in desert areas, but their efficiency is too low. Summary of the Invention

[0021] like Figure 1 As shown, a desert underground water collection device with pump suction function is used to collect and lift groundwater near the surface in desert areas. Its structure includes an underground water collection unit 1, a wind-powered pump suction lifting unit 2, and a water storage device 3. 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 respectively. The inlet end of the lifting pump 201 is connected to the underground water collection unit 1, and the outlet end of the lifting pump 201 is connected to the water storage device 3. The power input end of the lifting pump 201 is connected to the output end of the cam mechanism 202, and the input end of the cam mechanism 202 is connected to the output end of the sail mechanism 203. The water storage device 3 has a hollow structure with water distribution holes at the top for distributing the water inside. The distributed water can be used to supply water to the roots of plants. The underground water collection unit 1 is used to collect and lift groundwater near the surface, and the water collected by the underground water collection unit 1 is pumped and lifted into the water storage device 3 by the wind power pump lifting unit 2.

[0022] like Figure 1 and Figure 2 As shown, the underground water collection unit 1 includes a rigid water collection pipe 101, a primary capillary siphon lifting unit 102, a water storage and absorption unit 103, a secondary capillary siphon lifting unit 104, a multi-channel water storage and absorption device 105, and a connecting pipe 106. The rigid water collection pipe 101, the primary capillary siphon lifting unit 102, the water storage and absorption unit 103, and the secondary capillary siphon lifting unit 104 are vertically connected in sequence from bottom to top via the connecting pipe 106, forming a branch of the underground water collection unit. At least one branch of the underground water collection unit is connected to the multi-channel water storage and absorption device 105. Each section of the connecting pipe 106 inside the underground water collection unit 1 contains a water-absorbing medium for the absorption, storage, and transfer of water.

[0023] The rigid water collection pipe 101 is a rigid tubular hollow structure with a conical sealing structure at the bottom. The lower half is a perforated water collection section 101a and the upper half is a non-perforated water collection section 101b. The non-perforated water collection section 101b contains activated carbon, and groundwater enters and is stored in the activated carbon through the perforated water collection section 101a.

[0024] like Figure 2 and Figure 3 As shown, the primary capillary siphon lifting unit 102 and the secondary capillary siphon lifting unit 104 have the same structure, which are both tubular structures, consisting of a siphon unit shell 102a, a capillary bundle 102b, an absorbent sponge 102c, and a siphon unit plug 102d. The hollow tubular siphon unit shell 102a houses the capillary bundle 102b, and absorbent sponges 102c are provided at both ends of the capillary bundle 102b for anti-clogging protection. The siphon unit shell 102a has siphon unit plugs 102d at both ends, which are open tubular structures for communication and connection with the components at both ends.

[0025] The water storage and absorption unit 103 includes a water storage and absorption unit shell 103a, a water storage and absorption unit water storage and absorption medium 103b, and a water storage and absorption unit plug 103c. The water storage and absorption unit shell 103a has a hollow structure and the water storage and absorption unit water storage and absorption medium 103b is installed inside. The water storage and absorption unit plug 103c is installed at both ends of the water storage and absorption unit shell 103a for communication and connection with the components at both ends.

[0026] The multi-channel water storage and suction device 105 includes a multi-channel water storage and suction device housing 105a, a multi-channel water storage and suction device water storage and suction medium 105b, and a multi-channel water storage and suction device connector 105c. The multi-channel water storage and suction device housing 105a is a hollow structure, and the multi-channel water storage and suction device water storage and suction medium 105b is installed inside. The multi-channel water storage and suction device water storage and suction medium 105b is a substance with water storage and suction function. The multi-channel water storage and suction device connector 105c is installed on the outside of the multi-channel water storage and suction device housing 105a and is connected to the inlet end of the booster pump 201 through a pipeline.

[0027] The working process of the underground water collection unit 1 is as follows: the underground water collection unit 1 is vertically buried near the underground surface, and the multi-channel water storage and absorption device 105 is placed close to the ground. The rigid water collection pipe 101 is made of rigid material and is installed in the moist sand layer at a depth of 0.5 meters to 2 meters underground. In the underground sand layer near the surface, the upper layer of sand is generally drier than the lower layer of sand, and a humidity gradient is formed from bottom to top inside the entire device. Moisture in the underground sand near the surface diffuses from the perforated collection section 101a at the bottom of the rigid water collection pipe 101 into the pipe. It is absorbed and stored by the activated carbon, the water-absorbing medium inside the non-perforated collection section 101b at the top of the rigid water collection pipe 101. The primary capillary siphon lifting unit 102 lifts the moisture from bottom to top into the storage and absorption unit 103 via capillary action. The storage and absorption unit 103 then performs its water storage and absorption function. The secondary capillary siphon lifting unit 104 lifts the moisture from the storage and absorption unit 103 into the multi-channel storage and absorption device 105. The water stored in the multi-channel storage and absorption device 105 is supplied to the lift pump 201, which then draws, pumps, and lifts the moisture into the storage device 3. The negative pressure generated by the lift pump 201 also draws, pumps, and lifts the moisture inside the underground water collection unit 1, increasing the water absorption and lifting efficiency of the underground water collection unit. The connecting pipes 106 inside the underground water collection unit 1 are filled with water-absorbing media for the absorption, storage and transfer of water.

[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 5 As 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 provided with a sail fixing frame clamp 2031a, which is detachably fixed to 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 process of the wind power pump lifting unit 2 is as follows: the wind blows the sail 2033 to rotate, and the sail 2033 drives the cam 2022 to rotate through the sail shaft 2032. The cam 2022 drives the slide rod 2023 to move up and down reciprocally through the lever 2024. The groove 2023a on the outer circular 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 fixing frame 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 space of 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, the inlet check valve 2018 opens, and the outlet check valve 2019 closes. Under the action of atmospheric pressure outside inlet interface pipe 2012 and the negative pressure difference in the upper chamber of pump body 2011, fluid is drawn into the upper chamber of pump body 2011 from the inlet interface pipe.

[0034] When piston 2017b moves upward, positive pressure is generated in the upper chamber of pump body 2011, the inlet check valve 2018 closes, and the outlet check valve 2019 opens. Under the action of atmospheric pressure outside outlet interface pipe 2013 and the positive pressure difference between the upper chamber of pump body 2011 and the fluid, fluid is forced out from the outlet interface pipe through the upper chamber of pump body 2011.

[0035] Under the action of wind, the wind power pumping and lifting unit realizes the continuous suction and pumping flow of fluid from the inlet interface pipe 2012 to the outlet interface pipe 2013.

[0036] The power for water absorption and transport in the entire device comes partly from the humidity gradient of water from bottom to top inside the device and the free diffusion of water, the capillary siphon effect of activated carbon and water storage medium pores, and the capillary siphon effect of capillary bundles. The other part comes from the suction and pumping action of the booster pump.
