Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pumping and drainage equipment, and in particular to a wind-driven channel groundwater self-pumping and drainage system. Background Art

[0002] In canal projects in seasonally frozen regions, rising groundwater levels can lead to high moisture content in the channel foundation soil, which can easily trigger uneven frost heave, resulting in bulging and cracking of the lining structure. This freeze-thaw damage mechanism is particularly prominent in large, remote canal systems without access to power grids. Traditional electrically driven drainage systems, constrained by energy shortages, struggle to promptly remove seepage water, exacerbating structural damage and posing a dual threat to regional ecological security and economic development.

[0003] For canals with high groundwater levels, high moisture content in the channel foundation soil is a key factor in triggering frost heave damage. Current drainage technologies for these canals are costly and inefficient. Existing sand and gravel filter layer drainage technology requires regular refurbishment, resulting in high maintenance costs. Electric deep-well pumping and drainage technologies require continuous power supply, which is difficult to obtain in remote areas and results in high equipment costs. Summary of the Invention

[0032] Example 1

[0033] like Figure 1 、 Figure 2As shown, the present invention provides a wind-driven channel groundwater self-pumping and drainage system, through which the channel base water can be pumped out and put into the channel for use. The wind-driven channel groundwater self-pumping and drainage system includes a wind drive device and a protective device, which are fixedly connected to the protective device. The wind drive device includes a wind-collecting fan 1, a transmission mechanism, a piston mechanism and a water inlet mechanism. The blades of the wind-collecting fan 1 are arc-shaped, with 12 blades. The wind-collecting fan 1 is used to convert wind energy into mechanical energy to drive the entire system to operate. Figure 3 As shown, the ventilation fan 1 is fixedly connected to the transmission mechanism, which is used to convert the mechanical energy of the ventilation fan 1 into linear reciprocating motion of the piston mechanism, thereby achieving mechanical energy transmission. The transmission mechanism and the piston mechanism are fixedly connected by a vertical rod 16. The piston mechanism is placed in the water inlet mechanism. The water inlet mechanism is used to filter impurities and improve water inlet efficiency when pumping groundwater. The piston mechanism is used to pump groundwater under the action of the transmission mechanism.

[0034] The structure of the transmission mechanism is as follows Figure 3 As shown, the transmission mechanism includes a rotating shaft 4, a first large sprocket 5, a second large sprocket 6, a first chain 9, a second chain 10, a first small sprocket 7, a second small sprocket 8, a cross bar 12, a transmission rod 11 and a transmission shaft 15. The first large sprocket 5 and the second large sprocket 6 have the same specifications, and the first small sprocket 7 and the second small sprocket 8 have the same specifications. The first small sprocket 7 and the second small sprocket 8 are fixedly sleeved on the rotating shaft 4. The first small sprocket 7 is connected to the first large sprocket 5 through the first chain 9, and the second small sprocket 8 is connected to the second large sprocket 6 through the second chain 10. The first large sprocket 5 and the second large sprocket 6 are sleeved on both ends of a fixed shaft 13. The first large sprocket 5 and the first small sprocket 7 rotate in the same direction at the same time under the drive of the first chain 9. The second large sprocket 6 and the second small sprocket 8 are the same as above.

[0035] There are two transmission rods 11, one end of the two transmission rods 11 is hinged to the two ends of the cross bar 12, and the other ends of the two transmission rods 11 are hinged to the first large sprocket 5 and the second large sprocket 6 respectively. The rotating shaft 4 is fixedly connected to the transmission shaft 15, and the transmission shaft 15 is welded to the rotating member 34. The rotating member 34 is fixedly connected to the wind collecting fan 1 through a connecting member 35. A water outlet 36 is provided at the end of the rotating member 34 and a water outlet space is left between the rotating member 34 and the transmission shaft 15. The other end of the rotating member 34 is rotatably connected to the tower rod 2, as shown in FIG. Figure 6 shown.

[0036] The rotation of the wind-collecting fan 1 drives the rotating part 34 to rotate, the rotation of the rotating part 34 drives the transmission shaft 15 to rotate, the transmission shaft 15 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the first small sprocket 7 and the second small sprocket 8 to rotate, and then drives the first large sprocket 5 and the second large sprocket 6 to rotate, the first large sprocket 5 and the second large sprocket 6 rotate to drive the transmission rod 11 to move up and down, and the rotating part 34 is rotatably connected to the tower rod 2.

[0037] The first large sprocket 5 and the fixed shaft 13, and the second large sprocket 6 and the fixed shaft 13 are all rotationally connected. The fixed shaft 13 is fixed on the mounting plate 14. The fixed shaft 13 plays a supporting role, so that the first large sprocket 5 and the second large sprocket 6 rotate in place under the action of the fixed shaft 13.

[0038] A vertical rod 16 is fixedly connected to the middle part of the cross bar 12. The transmission rod 11 drives the cross bar 12 to move up and down, and the cross bar 12 drives the vertical rod 16 to reciprocate up and down. A limiting sleeve 17 is provided on the vertical rod 16. The limiting sleeve 17 is fixedly mounted on the mounting plate 14. The vertical rod 16 and the limiting sleeve 17 are slidably connected. The limiting sleeve 17 is used to limit the vertical rod 16 so that the vertical rod 16 can only reciprocate up and down, thereby ensuring the stability of the movement of the vertical rod 16.

[0039] A sealing device using an existing structure is provided outside the transmission mechanism, which does not affect its transmission and is used to prevent the internal structure from rusting and affecting its service life. Since the existing technology is used, the structure will not be elaborated in detail in this invention.

[0040] The protective device includes a guardrail 3 and a tower pole 2. The guardrail 3 is fixedly connected to the tower pole 2. The tower pole 2 is arranged at intervals in the longitudinal direction of the channel. The guardrail 3 serves to connect, fix and support the tower pole 2.

[0041] The water inlet mechanism includes a honeycomb permeable grid pipe 18, a three-way joint 20 and a geotextile 19. Figure 5 As shown, the outer layer of the permeable grid pipe 18 is wrapped with a geotextile 19. The permeable grid pipe 18 is a durable pipe made of polyethylene, and its corrosion resistance can meet the needs of long-term underground use. The pipe body structure of the permeable grid pipe 18 is based on a honeycomb permeable grid. Through a special production process, multiple layers of grids are staggered to form a three-dimensional support system with significantly enhanced thickness. This design not only ensures the structural stability of the pipe when it is subjected to high loads, but also greatly increases the water flow cross-sectional area through the staggered gaps between the honeycomb grids, thereby improving the overall water collection efficiency. In order to maintain long-term permeability, the outer layer of the permeable grid pipe 18 is specially wrapped with a geotextile 19 filter layer to effectively prevent impurities such as mud and sand from entering the grid and causing blockage. This structure achieves a comprehensive balance of bearing capacity, permeability and durability through the systematic integration of material optimization, structural innovation and protective design. The permeable grid pipes 18 are fixedly connected by the joints on both sides of the tee joint 20. The tee joint 20 is used to connect the permeable grid pipes 18 and the piston mechanism. The joint at the top of the tee joint 20 is fixedly connected to the tower pole 2, which is used to support other structures.

[0042] like Figure 4As shown, the piston mechanism includes a first water-passing piston 21 and a second water-passing piston 22. The first water-passing piston 21 is fixedly mounted inside the tower mast 2 via a bottom fixing pile 33. The second water-passing piston 22 is fixedly connected to the crossbar 12 via a vertical rod 16 fixed at the top. The second water-passing piston 22 can move up and down to generate pressure to pump water. The first water-passing piston 21 is the fixed part, and cooperates with the second water-passing piston 22 to efficiently pump water.

[0043] The first water flow piston 21 includes a first water flow port 23, a first water flow channel 24, a first physical piston 25, a first water flow ball 26 and a first piston tip 27. The first water flow channel 24 is opened in the middle of the first physical piston 25, three first water flow ports 23 are opened on the side wall of the first piston tip 27, and the first water flow ball 26 is placed in the first piston tip 27.

[0044] The second water flow piston 22 includes a second water flow port 28, a second water flow channel 29, a second physical piston 30, a second water flow ball 31 and a second piston tip 32. The second water flow channel 29 is opened in the middle of the second physical piston 30, and three second 28 water flow ports are opened on the side wall of the second piston tip 32. The second water flow ball 31 is placed in the second piston tip 32.

[0045] Figure 4 (a) is a diagram showing the various structural states when the second water-passing piston 22 rises. Figure 4 (b) is a diagram of the various structural states when the second water-passing piston 22 descends. As can be seen from the figure, when the second water-passing piston 22 rises under the action of the transmission mechanism, the first water-passing ball 26 rises, and the groundwater rises into the chamber between the first water-passing piston 21 and the second water-passing piston 22 through the first water-passing channel 24; when the second water-passing piston 22 descends under the action of the transmission mechanism, the first water-passing ball 26 descends to block the first water-passing channel 24, and the groundwater does not descend. The second water-passing ball 31 rises, and the groundwater in the chamber rises through the second water-passing channel 29 to above the second water-passing piston 22. This reciprocating process achieves the purpose of efficient water pumping.

[0046] When the wind-driven channel groundwater self-pumping and drainage system provided by the present invention is used, when wind blows through the curved blades of the ventilation fan 1, a pressure difference is generated on both sides of the blades to drive the wind wheel to rotate. The ventilation fan 1 rotates to drive the transmission shaft 15 to rotate, the transmission shaft 15 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the first small sprocket 7 and the second small sprocket 8 to rotate, and then drives the first large sprocket 5 and the second large sprocket 6 to rotate. The rotation of the first large sprocket 5 and the second large sprocket 6 drives the transmission rod 11 to move up and down, the transmission rod 11 drives the cross bar 12 to move up and down, and the cross bar 12 drives the vertical rod 16 to reciprocate up and down, forming a vacuum at the tower rod 2. When the second water-passing piston 22 rises under the action of the transmission mechanism, the first water-passing ball 26 rises, and the groundwater rises to the chamber between the first water-passing piston 21 and the second water-passing piston 22 through the first water-passing channel 24; when the second water-passing piston 22 descends under the action of the transmission mechanism, the first water-passing ball 26 descends to block the first water-passing channel 24, and the groundwater does not descend. The second water-passing ball 31 rises, and the groundwater in the chamber rises to above the second water-passing piston 22 through the second water-passing channel 29. In this reciprocating manner, the purpose of efficient water pumping is achieved, and the pumped groundwater is discharged to the channel through the water outlet 36, lowering the groundwater level and preventing the channel foundation soil from frost heaving and damaging the lining.

[0047] Therefore, the present invention adopts the above-mentioned wind-driven channel groundwater self-pumping and drainage system, uses natural wind energy to drive the piston mechanism to extract the channel base groundwater in the pre-arranged honeycomb permeable grid pipe, and pushes the groundwater into the channel through the wind-collecting fan, using natural renewable resources to solve the channel frost heave problem. At the same time, the water is discharged back into the channel for irrigation and other uses, increasing water-saving benefits. Tower poles are arranged at intervals to set up protective fences, which have both protective functions and save protection costs.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
