Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and energy related equipment, and in particular to a bionic groundwater extraction device. Background Art

[0002] Groundwater refers to water stored in the gaps in rocks below the ground. The storage of groundwater is like forming a huge reservoir underground. With its stable water supply conditions and good water quality, it has become an important source of water for agricultural irrigation, industrial and mining enterprises, and urban domestic water. It has become an important water resource that is indispensable to human society, especially in arid and semi-arid areas where there is a shortage of water on the surface. Groundwater often becomes the main source of local water supply.

[0003] At present, groundwater extraction usually adopts the method of lifting the water head to extract water. However, the above method requires the use of secondary energy supply. Although it can achieve rapid and large-scale water extraction, it has the problems of high cost and high carbon emissions, and cannot achieve energy-saving and emission-reduction water extraction. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a bionic groundwater extraction device, which utilizes the principle of plant evaporation and water absorption, can directly use solar energy and wind energy to raise the water level and extract water, has the advantages of being economical, environmentally friendly, and low in cost, and achieves energy-saving and emission-reduction water extraction.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A bionic groundwater extraction device includes an evaporation pumping system and a condensation water collection system; wherein:

[0007] The evaporation pumping system comprises a water pipe, an evaporation box, a regulating reservoir arranged in the evaporation box, and evaporation blades arranged on the regulating reservoir; the upper end of the water pipe passes through the bottom surface of the evaporation box and the bottom surface of the regulating reservoir in sequence, and then closely contacts the bottom of the evaporation blade, and the lower end of the water pipe is used to connect to groundwater;

[0008] The condensation water collection system comprises a condensation water collection tank and an air cooling pipe arranged on the condensation water collection tank; the evaporation tank is connected to the condensation water collection tank through an air guide pipe.

[0009] The working principle of the above-mentioned bionic groundwater extraction device is:

[0010] In nature, tree leaves will evaporate under the action of solar heat. The water loss caused by evaporation reduces the pressure of liquid water in the leaves relative to atmospheric pressure. This negative pressure causes liquid water in the soil to be transported from the roots of the tree to the leaves to maintain hydration. In the plant kingdom, the height of water transport by evaporation can reach 110 meters, such as redwood. The preparation of a bionic evaporation pumping device based on the concept of evaporation water transport can provide a new idea for solving the problem of groundwater extraction in arid areas. The bionic groundwater extraction device of the present invention uses the above concept. When working, the water pipe, evaporation blades and regulating reservoir are first placed in water for vacuum saturation, so that the regulating reservoir is filled with a large amount of water, and the lower end of the water pipe is connected to the groundwater, so that a negative pressure environment can be formed inside the water pipe during the evaporation process; under the action of solar energy, the evaporation blades will continuously evaporate water vapor, and the water vapor will enter the condensation water collection tank along the air pipe, and condense into water droplets when it contacts the air cooling pipe, and the water droplets fall to the bottom of the condensation water collection tank.

[0011] In a preferred embodiment of the present invention, the water conduit is a loop-type water conduit, and the inside of the loop-type water conduit contains hard microporous fine granular material with water absorption function. The loop-type water conduit can bear the dead weight of the hard microporous fine granular material, and prevent the hard microporous fine granular material from being over-compressed and blocking the water flow.

[0012] Furthermore, the loop-type water conduit includes a plurality of loop pipes connected end to end in sequence; each loop pipe includes a lower vertical section, an upper vertical section, and a loop section connected between the lower vertical section and the upper vertical section. In the above structure, the loop section adopts a turning setting, and the loop section turns downward from the upper end of the lower vertical section and is directly connected to the lower end of the upper vertical section; the turning setting of the loop section can bear the dead weight of the hard microporous fine granular material; by setting a plurality of loop pipes, it is further ensured that the hard microporous fine granular material will not be compressed, thereby improving the water absorption effect.

[0013] Preferably, the evaporation blade is a micro-nanopore evaporation blade. The purpose is that the micro-nanopore evaporation blade uses the extremely strong micropore capillary effect and the sealing effect of the regulating reservoir to prevent the water in the loop water pipe from flowing back to the bottom of the loop water pipe.

[0014] Preferably, the air inlet of the air cooling pipe is a trumpet-shaped bell mouth. The purpose is to better receive wind force, so that the air cooling pipe can be cooled, and the water vapor in the condensation water collection tank can be cooled and condensed into water droplets. The air outlet of the air cooling pipe passes through the condensation water collection tank and then passes out of the condensation water collection tank; that is, the air cooling pipe is partially embedded in the condensation water collection tank, and the water vapor can be cooled, so that the water vapor condenses into water droplets.

[0015] Preferably, the air cooling pipe includes a vertical pipe and a horizontal pipe connected to the vertical pipe, the diameter of the vertical pipe is smaller than the diameter of the horizontal pipe, the bell mouth is arranged on the vertical pipe, and the air outlet of the air cooling pipe is arranged on the horizontal pipe. In the above structure, the compression and diffusion heat absorption of the air are realized by changing the pipe diameter, and part of the vertical pipe and part of the horizontal pipe are embedded in the condensation water collecting tank, so as to play the role of cold preservation and heat insulation.

[0016] Preferably, there are multiple air cooling pipes, and the multiple bell mouths are arranged in multiple directions, so as to enable the air cooling pipes to receive wind from different directions, thereby improving the utilization rate of wind energy.

[0017] Preferably, the side of the condensate water collection tank is connected with an outlet pipe; the outlet pipe is provided with a valve assembly; the valve assembly includes a valve cavity provided on the outlet pipe, a valve port provided at the connection between the valve cavity and the outlet pipe, a rubber ring provided on the valve port, and a blocker provided in the valve cavity for closing and opening the valve port; a float is provided in the condensate water collection tank, and the blocker is connected to the float by a connecting line. In the above structure, after the bionic groundwater extraction device has been running for a long time, the water level in the condensate water collection tank becomes higher, the float floats up with the water level, drives the connecting line to move, and then the connecting line drives the blocker to move in the valve cavity, so that the blocker is separated from the rubber ring on the valve port, the valve port is opened, and the excess water in the condensate water collection tank can automatically flow out from the outlet pipe, so as to achieve the purpose of water use; by providing the rubber ring, the connection between the blocker and the rubber ring is more tightly, and the sealing performance is improved; when the water in the condensate water collection tank becomes less, the float moves downward, the connecting line is loosened, and the blocker automatically sticks to the rubber ring under the action of water pressure, so as to achieve the purpose of closing the valve port.

[0018] Preferably, the blocker is a conical spherical blocker, and the conical spherical blocker includes a sphere and a cone; the diameter of the sphere is larger than the diameter of the valve port, the maximum diameter of the cone is smaller than the diameter of the valve cavity, the interior of the cone is a hollow structure, and the surface of the cone is provided with water holes. In the above structure, the maximum diameter of the cone is smaller than the diameter of the valve cavity, so that the conical spherical blocker can move in the valve cavity, the diameter of the sphere is larger than the diameter of the valve port, so that the sphere can block the valve port, and in addition, the cone can play a guiding role, ensuring that the sphere can be aligned with the valve port, so that the valve port can be successfully closed, preventing the sphere from being misaligned with the valve port, and providing water holes to ensure smooth drainage after the valve port is opened.

[0019] Preferably, the air guide pipe is obliquely arranged between the evaporation box and the condensation water collecting box, one end of the air guide pipe is the air inlet end, and the other end is the air outlet end; the side of the evaporation box is provided with an air outlet, and the side of the condensation water collecting box is provided with an air inlet; the air inlet end of the air guide pipe is connected to the air outlet, and the air outlet end of the air guide pipe is connected to the air inlet; the height of the air outlet is lower than the height of the air inlet. The above structure is adopted to facilitate the transportation of water vapor in the evaporation box to the condensation water collecting box, and the air guide pipe adopts a narrow and long tube to form a "chimney effect", thereby promoting the evaporation and water pumping rate.

[0020] Preferably, an overflow pipe is provided between the evaporator and the condensation water collecting tank, the overflow pipe is arranged obliquely and downwardly in the direction of the condensation water collecting tank, the water inlet of the overflow pipe is connected to the air outlet; the water outlet of the overflow pipe is connected to the condensation water collecting tank; a water retaining plate is provided on the air outlet. In the above structure, the position height of the water inlet of the overflow pipe is higher than the position height of the water outlet of the overflow pipe. When water vapor condenses into water droplets on the air guide pipe, the water retaining plate can be provided to prevent the water droplets from flowing into the evaporator. After being blocked by the water retaining plate, the water droplets will directly flow into the overflow pipe, and finally flow from the overflow pipe into the condensation water collecting tank for storage.

[0039] See also Figure 1 The thickness of the micro-nanopore evaporation blade is greater than 4 mm. The upper end of the water guide pipe 1 is in direct contact with the micro-nanopore evaporation blade but not sealed.

[0040] See also Figure 1-Figure 2 The air inlet of the air cooling pipe 4 is a trumpet-shaped trumpet mouth. The purpose is to better receive wind power, so that the air cooling pipe 4 can be cooled, and the water vapor in the condensation water collection tank 5 can be cooled and condensed into water droplets.

The other end of the horizontal pipe is the air outlet, and the air outlet passes through the side of the condensation water collecting tank 5. The height of the bell mouth is higher than that of the air outlet. The air inlet and the air outlet of the air cooling pipe 4 are both connected to the atmosphere. In the above structure, the compression and diffusion heat absorption of air are realized by changing the pipe diameter. Part of the vertical pipe and part of the horizontal pipe are embedded in the condensation water collecting tank 5, so that the effect of cold preservation and heat insulation can be achieved.

[0042] See also Figure 1-Figure 2 The number of the air cooling pipes 4 is multiple, and the multiple bell mouths are arranged in multiple directions. The purpose is to enable the air cooling pipes 4 to receive wind from different directions, thereby improving the utilization rate of wind energy.

[0043] See also Figure 1-Figure 2 In this embodiment, there are four air-cooling pipes 4, and the four bell mouths face the four directions of east, west, south and north respectively, so as to receive wind from four different directions.

[0044] See also Figure 1 and Figure 3-Figure 5 A water outlet pipe 6 is connected to the side of the condensate collecting tank 5; a valve assembly is provided on the water outlet pipe 6; the valve assembly includes a valve cavity provided on the water outlet pipe 6, a valve port provided at the connection between the valve cavity and the water outlet pipe 6, a rubber ring 10 provided on the valve port, and a blocker 7 provided in the valve cavity for closing and opening the valve port; a float 8 is provided in the condensate collecting tank 5, the float 8 floats on the water surface, and the blocker 7 is connected to the float 8 through a connecting line 9. In the above structure, after the bionic groundwater extraction device has been running for a long time, the water level in the condensate collecting tank 5 becomes higher, and the float 8 floats up as the water level becomes higher, driving the connecting line 9 to move, and then the connecting line 9 drives the blocker 7 to move in the valve cavity, so that the blocker 7 is separated from the rubber ring 10 on the valve port, the valve port is opened, and the excess water in the condensate collecting tank 5 can automatically flow out from the outlet pipe 6 to achieve the purpose of water use; by setting the rubber ring 10, the connection between the blocker 7 and the rubber ring 10 is tighter, and the sealing performance is improved; when the water in the condensate collecting tank 5 becomes less, the float 8 moves downward, the connecting line 9 is loosened, and the blocker 7 automatically sticks to the rubber ring 10 under the action of water pressure, so as to achieve the purpose of closing the valve port; the outlet pipe 6 uses the principle of the float 8 to realize automatic water discharge, which can not only ensure that the condensate collecting tank 5 is in a closed state, but also avoid excessive water collection in the condensate collecting tank 5, and also save manpower management costs.

[0045] See also Figure 1 and Figure 3-Figure 5The diameter of the valve cavity is larger than the diameter of the water outlet pipe 6. The valve cavity is composed of a large-diameter pipe. The valve cavity divides the water outlet pipe 6 into two sections of water pipes, one end of which is connected to the condensation water collection tank 5, and the other end is connected to one end of the large-diameter pipe, and the other end of the large-diameter pipe is connected to one end of the other section of water pipe. The valve port is set at the end of the large-diameter pipe away from the condensation water collection tank 5.

[0046] See also Figure 1 and Figure 3-Figure 5 The blocker 7 is a cone-spherical blocker, which includes a sphere and a cone arranged on the sphere; the diameter of the sphere is larger than the diameter of the valve port, the maximum diameter of the cone is smaller than the diameter of the valve cavity, the interior of the cone is a hollow structure, and the surface of the cone is provided with water holes. In the above structure, the diameter of the cone is constantly changing, and the diameter of the cone gradually increases in the direction away from the sphere. The maximum diameter of the cone is smaller than the diameter of the valve cavity, so that the cone-spherical blocker can move in the valve cavity. The diameter of the sphere is larger than the diameter of the valve port, so that the sphere can block the valve port. In addition, the cone can play a guiding role, ensuring that the sphere can be aligned with the valve port, so that the valve port can be successfully closed, preventing the sphere from being misaligned with the valve port, and providing water holes to ensure smooth drainage after the valve port is opened.

[0047] See also Figure 1 and Figure 3-Figure 5 In order to ensure that the ball can be aligned with the valve port, the maximum diameter of the cone can be slightly smaller than the diameter of the valve cavity.

[0048] See also Figure 1 and Figure 3-Figure 5 A portion of water is pre-stored in the condensation water collecting tank 5, which can play the role of water sealing the condensation water collecting tank 5. When the water level is low, the conical spherical blocker is tightly blocked by the water pressure (the pipe hole of the water outlet pipe 6), and the float 8 floats on the water surface normally, and does not generate a pulling force on the conical spherical blocker, so that water can be collected and stored.

[0049] See also Figure 1 The air duct 11 is tilted between the evaporation box 3 and the condensation water collecting box 5. One end of the air duct 11 is the air inlet end, and the other end is the air outlet end. The side of the evaporation box 3 is provided with an air outlet, and the side of the condensation water collecting box 5 is provided with an air inlet. The air inlet end of the air duct 11 is connected to the air outlet, and the air outlet end of the air duct 11 is connected to the air inlet. The height of the air outlet is lower than the height of the air inlet. The above structure is adopted to facilitate the transportation of water vapor in the evaporation box 3 to the condensation water collecting box 5. The air duct 11 is tilted, the air outlet end is located at an upper position, and the air duct 11 adopts a narrow and long tube, which can form a "chimney effect", thereby promoting the evaporation and water pumping rate.

[0050] See also Figure 1An overflow pipe 12 is provided between the evaporation box 3 and the condensation water collecting box 5. The overflow pipe 12 is inclined downward toward the direction of the condensation water collecting box 5. The water inlet of the overflow pipe 12 is connected to the air outlet; the water outlet of the overflow pipe 12 is connected to the condensation water collecting box 5; and a water retaining plate 13 is provided on the air outlet. In the above structure, the position height of the water inlet of the overflow pipe 12 is higher than the position height of the water outlet of the overflow pipe 12. When water vapor condenses into water droplets on the air guide pipe 11, the water retaining plate 13 can be provided to prevent the water droplets from flowing into the evaporation box 3. After being blocked by the water retaining plate 13, the water droplets will directly flow into the overflow pipe 12, and finally flow from the overflow pipe 12 into the condensation water collecting box 5 for storage.

[0051] When the outside temperature drops and the evaporation process is weak, the micro-nano pores in the micro-nano pore evaporation blades achieve pressure balance at the evaporation interface by shrinking the water column by a certain distance. The evaporation blades 2 with a certain thickness can ensure that the water column in the micro-nano pores has a sufficient shrinkage distance to form a balance between the capillary force and the Kelvin pressure at the evaporation interface; at the same time, the micro-nano pore evaporation blades use the extremely strong micropore capillary effect and the sealing effect of the regulating reservoir 15 to prevent the water in the loop water pipe from flowing back to the bottom of the water pipe 1.

[0052] The top of the evaporation box 3 is arranged to be inclined upward toward the direction of the condensation water collecting box 5 , so as to guide the water vapor in the evaporation box 3 to be transported toward the air guide pipe 11 .

[0053] See also Figure 1 , the working principle of the above-mentioned bionic groundwater extraction device is:

[0054] In nature, tree leaves will evaporate under the action of solar heat. The water loss caused by evaporation reduces the pressure of liquid water in the leaves relative to atmospheric pressure. This negative pressure causes liquid water in the soil to be transported from the roots of the tree to the leaves to maintain hydration. In the plant kingdom, the height of water transport by evaporation can reach 110 meters, such as redwood. The preparation of a bionic evaporation pumping device based on the concept of evaporation water transport can provide a new idea for solving the problem of groundwater extraction in arid areas. The bionic groundwater extraction device of the present invention uses the above concept. When working, the water pipe 1, the evaporation blade 2 and the regulating reservoir 15 are first placed in water for vacuum saturation, so that the regulating reservoir 15 is filled with a large amount of water, and the lower end of the water pipe 1 is connected to the groundwater, so that a negative pressure environment can be formed inside the water pipe 1 during the evaporation process; under the action of solar energy, the evaporation blade 2 will continuously evaporate water vapor, and the water vapor will enter the condensation water collection tank 5 along the air pipe 11, and condense into water droplets when it contacts the air cooling pipe 4, and the water droplets fall to the bottom of the condensation water collection tank 5. This embodiment makes full use of the plant evaporation water absorption principle, air cooling principle, and buoyancy principle, integrates the evaporation pumping system and the condensation water collection system, can directly use solar energy and wind energy to raise the water level and draw water, and has the advantages of being economical, environmentally friendly, and having low maintenance costs.
