Description

Technical Field

[0001] The present invention generally relates to the field of hydropower generation, and in particular to a water resource energy recovery device. Background Art

[0002] Agricultural irrigation mainly refers to the irrigation work in agricultural cultivation areas, which is a vital part of agricultural production. In irrigation, rivers and wells are usually used as the main water source. In northern my country, water resources are not as abundant as in the south, so it is common to dig wells and pump groundwater through water pumps as the main way to obtain water.

[0003] For agricultural irrigation, the depth of well digging cannot be determined due to environmental factors and is generally around 20m-100m. During the pumping process, the water flow is only used for irrigation, but the potential energy of the water flow is not effectively utilized.

[0004] The potential energy of water flow is usually converted into electrical energy by a hydro-turbine generator, which is an important hydro-power generation equipment. It uses the energy of water flow to convert it into mechanical energy through a turbine, and then drives the generator rotor to rotate, ultimately realizing the conversion of mechanical energy into electrical energy.

[0005] However, there are many unfavorable factors in the application of hydro-turbine generators in agriculture. On the one hand, agricultural wells are deep, and the diameter of the wellhead is not conducive to installing hydro-turbine generators in the wells. On the other hand, in the initial stage of pumping water out of the well, the potential energy of the water flow is relatively small, making it difficult to drive the hydro-turbine generator to rotate. Summary of the invention

[0006] In view of the problems existing in the above-mentioned prior art, the present invention provides a water resource energy recovery device, comprising: a vertical pipe, which is vertically placed outside a water well, and the top of which is interconnected with a water pumping pipeline in the water well; a rotating shaft, which is located in the vertical pipe and is coaxially arranged with the vertical pipe, and is also rotatably connected to the vertical pipe; a guide umbrella, which is connected to the top of the rotating shaft, and its opening direction is toward the bottom of the rotating shaft; a plurality of guide blades, which are fixed on the upper surface of the guide umbrella and are distributed in an arc from the middle of the guide umbrella to the side direction; spiral blades, which are located below the guide umbrella and are fixed to the outer surface of the rotating shaft and are distributed in a spiral along the length direction of the rotating shaft; the end of the rotating shaft passes through the vertical pipe, and a generator is connected to the end of the rotating shaft. By having the above-mentioned technical features, water is drawn into the vertical pipe under the action of the water pump. In the process of falling from the top, the water will first impact on the outer arc surface of the guide umbrella, and flow to the surroundings under the guidance of the guide umbrella. In the process of flowing, the water flows into the channel formed by the guide blades, and drives the guide blades to rotate, and then drives the rotating shaft to rotate. Compared with the traditional water flow directly colliding with the water wheel, the impact force is larger, and it is impossible to drive the water wheel to rotate smoothly and in time. In the present invention, as the rotating shaft rotates, the spiral blades also rotate. As the water flows, they will enter the channel of the spiral blades and accelerate the rotation of the rotating shaft, and finally drive the generator to rotate to generate electricity. The guide umbrella absorbs the impact force of the initial water flow, which not only drives the rotation of the rotating shaft but also guides the water flow.

[0007] In some embodiments, the vertical pipe includes an annular water storage chamber, the water storage chamber is connected to the edge of the guide umbrella at the top and the starting part of the spiral blade at the bottom. Thus, the guide umbrella guides the initial water flow into the water storage chamber, thereby accumulating the potential energy of the water flow, temporarily slowing down the speed of the water flow flowing directly downward, and thus accumulating energy for the water flow to impact the spiral blade.

[0008] In some embodiments, the guide umbrella includes an umbrella top, the inner concave surface of the umbrella top is fixed to the top of the rotating shaft; umbrella pieces, the umbrella pieces are evenly distributed on the umbrella top and are rotatably connected to the umbrella top, and the guide blades are fixed on the outer arc surface of the umbrella pieces; and also includes a flexible cloth, the flexible cloth is located between adjacent umbrella pieces and is connected to adjacent umbrella pieces. Therefore, as the flow potential of the water flow increases, the impact of the water flow on the guide umbrella also increases. Therefore, as the flow potential of the water flow increases, the umbrella pieces are driven to bend and rotate, thereby ensuring the flow rate of the water flow in the later period and increasing the service life of the guide umbrella. As the umbrella pieces bend, the guiding angle of the guide umbrella to the water flow is also deflected, thereby increasing the direct impact of the water flow on the spiral blades.

[0009] In some embodiments, a driving mechanism for driving the umbrella piece and the umbrella top to rotate is also provided between each umbrella piece and the rotating shaft, and the driving mechanism includes a driving rod, one end of the driving rod is rotatably connected to the inner arc surface of the umbrella piece, and the other end extends in the direction of the rotating shaft; a driving block, the driving block is slidably connected to the rotating shaft along the length direction of the rotating shaft, and the driving block is also rotatably connected to the other end of the driving rod; a spring is respectively connected to the driving block and the rotating shaft, and is used to limit the umbrella piece from rotating with the umbrella top in the direction of the bottom of the umbrella top. Thus, in the early stage of the water flow, the flow rate of the water flow is not large, the flow potential is small, and the impact force on the guide umbrella is small, so that while guiding the water flow, the rotation of the rotating shaft is also driven, and as the potential energy of the water flow increases, the energy of the water flow is fully able to drive the rotation of the spiral blades, and the setting of the guide umbrella will slow down the potential energy of the water flow, so through the setting of the driving mechanism, when the potential energy of the water flow reaches a certain energy, it will drive the umbrella piece to bend and the spring to contract, thereby avoiding the water flow, ensuring the smooth flow of the downstream, and the high-speed operation of the rotating shaft.

[0010] In some embodiments, the outer circumference of the rotating shaft is provided with a plurality of slide grooves along the length direction of the rotating shaft for accommodating the sliding of the driving block, and one end of the spring is fixed to the bottom wall of the slide groove, and the other end is fixed to the bottom wall of the driving block. Thus, the driving block is located in the slide groove, and the structural structure protruding from the outside of the rotating shaft is reduced, which can not only reduce the overall weight of the rotating shaft, but also reduce the friction between the rotating shaft and the surrounding environment.

[0011] In some embodiments, a limit block is fixedly connected to each side of the driving block, and a slot is provided on the opposite inner wall of the slide slot to cooperate with the limit block to slide. Therefore, the limit block and the slot cooperate with each other, so that the driving block and the slide slot are limited from being separated from each other during the rotation of the rotating shaft, thereby ensuring the stability of the driving mechanism.

[0012] In some embodiments, a water-receiving plate is fixedly connected to one side of the driving block away from the rotating shaft, and the end of the water-receiving plate extends toward the edge of the umbrella piece. Therefore, as the potential energy of the water flow increases, the water flow will also impact the water-receiving plate during the downward flow, thereby driving the displacement of the driving block, thereby improving the efficiency of the umbrella piece bending.

[0013] In some embodiments, the water-facing plate is located within the shielding range of the umbrella pieces. Therefore, the umbrella pieces always guide the water flow, and due to the positional relationship between the water-facing plate and the umbrella pieces, when the water flow is large, the direct impact of the water flow on the water-facing plate is reduced, which is not easy to cause damage to the water-facing plate, and also reduces the impact on the potential energy of the water flow.

[0014] In some embodiments, the rotating shaft outside the vertical tube is coaxially fixed with a driving gear, and the generator rotor is coaxially fixed with a driven gear meshing with the driving gear. Thus, the driving gear and the driven gear drive the generator to start and generate electricity.

[0015] In some embodiments, the slide slot is provided with an installation slot which is interconnected with the card slot and is used for installing the drive block, thereby facilitating the installation and resetting of the drive block by the staff, and improving the efficiency of installation and subsequent maintenance and repair.

[0016] It should be understood that the contents described in the summary of the invention are not intended to limit the key or important features of the embodiments of the present disclosure, nor are they intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Hereinafter, preferred embodiments (or implementation modes) of the present invention will be described in detail with reference to the accompanying drawings.

[0020] The present invention provides a water resource energy recovery device. Figure 1 FIG. 1 shows a schematic diagram of the installation position of a water resource energy recovery device provided by an embodiment of the present invention. Figure 1 As shown, the energy recovery device is located at the valve connection outside the water well and is interconnected with the other end of the valve, including a vertical pipe 1, a rotating shaft 2 is coaxially arranged inside the vertical pipe 1, a guide umbrella 3 is connected to the top of the rotating shaft 2, a spiral blade 21 is fixed to the circumference of the rotating shaft 2, the bottom end of the rotating shaft 2 passes through the vertical pipe 1 and is rotatably connected to the vertical pipe 1, and the lower end of the rotating shaft 2 is connected to a generator 13. After the valve is opened, the water pump starts, driving the water in the water well to flow to the outside of the water well and into the vertical pipe 1. The initial water flow potential energy is insufficient, and it impacts on the guide umbrella 3, and drives the guide umbrella 3 to rotate, and at the same time drives the rotating shaft 2 to rotate, and also makes the spiral blade 21 rotate synchronously. With the flow of the flow, it flows into the space separated by the spiral blade 21, thereby accelerating the rotation of the spiral blade 21 and improving the rotation of the rotating shaft 2, and finally driving the generator 12 rotor to rotate. The initial impact of the water flow on the guide umbrella 3 drives the rotation of the spiral blade 21, thereby reducing the impact of subsequent water flow on the spiral blade 21. Compared with the traditional hydro-generator 13, its initial startup is fast and energy waste is small.

[0021] Reference below Figure 2-Figure 7 To describe a water resource energy recovery device of the present invention.

[0022] Figure 2 The internal structure diagram of a vertical pipe 1 of a water resource energy recovery device provided by an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, a water resource energy recovery device provided in this embodiment includes a vertically arranged vertical pipe 1, a rotating shaft 2 located in the vertical pipe 1 and rotating coaxially with the vertical pipe 1, the circumferential side of the rotating shaft 2 is rotatably connected to the inner wall of the vertical pipe 1 through a frame 11, and the lower end of the rotating shaft 2 passes through the vertical pipe 1 and is rotatably connected to the bottom wall of the vertical pipe 1; a guide umbrella 3 is fixedly connected to the upper end of the rotating shaft 2, and a spiral blade 21 is arranged below the guide umbrella 3, the spiral blade 21 is arranged along the length direction of the rotating shaft 2, and is fixedly connected to the rotating shaft 2; and the lower end of the rotating shaft 2 is connected to a generator 13.

[0023] An annular water storage chamber 12 is provided in the middle of the vertical pipe 1. The upper part of the water storage chamber 12 is connected to the edge of the guide umbrella 3, and the lower part of the water storage chamber 12 is connected to the top of the spiral blade 21, so that space is left between the guide umbrella 3 and the spiral blade 21, which is convenient for the water flow to be concentrated and diverted to the spiral blade 21.

[0024] Figure 3 FIG. 1 is a schematic diagram showing the structure of a guide umbrella 3 in a water resource energy recovery device provided by an embodiment of the present invention. Figure 3 As shown, the guide umbrella 3 includes an umbrella top 31 in the middle, and a plurality of umbrella pieces 32 connected and arranged at the edge of the umbrella top 31 and evenly distributed along the circumference of the umbrella top 31. The umbrella top 31 is in a cone shape as a whole, and its concave side is coaxially fixed to the top of the rotating shaft 2. The umbrella pieces 32 are hinged to each other at the edge of the umbrella top 31, and their hinge axes are perpendicular to the rotating shaft 2 to meet the requirement that each umbrella piece 32 rotates and gathers in the direction of the rotating shaft 2. A flexible cloth 33 for filling the gap between the umbrella pieces 32 is also arranged between adjacent umbrella pieces 32, and the edges of the flexible cloth 33 on both sides are connected to the edges of the umbrella pieces 32, so that when the umbrella pieces 32 are in the unfolded state, the flexible cloth 33 is spread out to fill the gap between the adjacent umbrella pieces 32, and when the umbrella pieces 32 are stored in the direction of the rotating shaft 2, the flexible cloth 33 is stored between the adjacent umbrella pieces 32 through its own elastic bending. Furthermore, an arc-shaped guide blade 321 is fixedly connected to the outer arc surface of each umbrella piece 32 , and the guide blade 321 extends from an end close to the umbrella top 31 to an end away from the umbrella top 31 .

[0025] When the water pump is turned on, the guide umbrella 3 is in the unfolded state, and there is a gap between the edge of the guide umbrella 3 and the side of the vertical pipe 1. The water flows into the vertical pipe 1 under the action of the water pump. Since the water flow is relatively dispersed at the beginning, the impact force of the water flow on the guide umbrella 3 is relatively small. The water flow impacts the guide umbrella 3 and flows on each umbrella sheet 32 ​​and the flexible sheet, and finally guides the water flow into the annular water storage chamber 12. The impact force of the water flow on the guide blade 321 is transmitted to the rotating shaft 2 and drives the rotating shaft 2 to rotate, and also drives the spiral blade 21 to rotate around the rotating shaft 2. The reciprocating impact of the water flow in the annular water storage chamber 12, part of the water flow flows into the channel of the spiral blade 21, and part of the water flow accumulates in the water storage chamber 12. As the water in the water storage chamber 12 is accumulated, the flow direction of the water flow is more concentrated and uniformly impacts the direction of the spiral blade 21, and the rotation speed of the spiral blade 21 is also accelerated. The power generation efficiency of the generator 13 is accelerated.

[0026] The unfolded guide umbrella 3 not only guides the water flow uniformly to the water storage chamber 12 at the initial stage of water flow, but also drives the initial rotation of the spiral blade 21. However, as the water flow stabilizes, the unfolded guide blade not only occupies the channel for water flow, but also reduces the water flow speed, and even poses a risk of impact damage to the guide umbrella 3. Therefore, a driving mechanism 4 for controlling the opening and closing of each umbrella piece 32 is also provided under each umbrella piece 32. Figure 4 FIG. 4 is a cross-sectional schematic diagram of a driving mechanism 4 in a water resource energy recovery device provided by an embodiment of the present invention. Figure 4As shown, the driving mechanism 4 includes a driving rod 41 located below the umbrella piece 32, a driving block 42 located below the driving rod 41, the upper end of the driving rod 41 is hinged at the edge of the umbrella piece 32, and the other end of the driving rod 41 is hinged on the driving block 42. A sliding groove 22 for accommodating the driving block 42 is provided on the peripheral side of the rotating shaft 2 along the length direction of the rotating shaft 2, so that the driving block 42 can slide back and forth along the axial direction of the rotating shaft 2. A spring 43 is also provided at the bottom of the driving block 42, the upper end of the spring 43 is fixedly connected to the driving block 42, and the lower end of the spring 43 is fixedly connected to the bottom wall of the spring 43, so that when the spring 43 is in the natural state, the umbrella piece 32 is in the expanded state under the support of the driving rod 41, and when the spring 43 is in the compressed state, the umbrella piece 32 rotates toward the direction of the rotating shaft 2.

[0027] Figure 5 FIG. 4 is a schematic diagram showing the structure of a driving block 42 in a water resource energy recovery device provided by an embodiment of the present invention. Figure 4 and Figure 5 As shown, the side walls of the driving block 42 in contact with the slide 22 are fixed with a limit block 44, and the slide 22 has a slot 23 that matches the fiber block at the position corresponding to the limit block 44, thereby limiting the separation of the limit block 44 from the slide 22, ensuring the normal operation of the driving mechanism 4, and the top of the slide 22 is also provided with a pair of mounting slots 24, one end of the mounting slot 24 is connected to the slot 23, and the other end is connected to the outer wall of the rotating shaft 2, so that the fiber block on the driving block 42 can be installed at the designated position of the rotating shaft 2 through the mounting slot 24. Moreover, under the elastic action of the spring 43, the sliding of the limit block 44 in the mounting slot 24 is also limited, ensuring the normal operation of the driving block 42.

[0028] Figure 6 FIG. 2 shows a cross-sectional view of a water resource energy recovery device provided by an embodiment of the present invention, wherein the guide umbrella 3 is in a gathered state except for the flexible cloth 33. Figure 6, a water-receiving plate 5 is connected to the side of the driving block 42 away from the chute 22. One side of the water-receiving plate 5 is fixed to the driving block 42, and the other side extends in the direction of the umbrella piece 32. However, the overall length of the water-receiving plate 5 does not exceed 1 cm, and when the umbrella piece 32 is not unfolded, it does not exceed the edge of the umbrella piece 32, and is entirely within the shielding range of the umbrella piece 32. When the umbrella piece 32 is in the unfolded state, as the water flow accumulates in the water storage chamber 12, the water flow will submerge the area of ​​the driving block 42. As the water flow flows, it will impact the water-receiving plate 5, and the impact force is transmitted to the driving block 42 and drives the driving block 42 to move toward the bottom of the chute 22, and elastically deforms the spring 43, and links the umbrella piece 32 to bend in the direction of the rotating shaft 2. When the water flow in the vertical pipe 1 is stabilized, the umbrella piece 32 is stably in a retracted state under the impact of the water flow, and the guide surface of the umbrella piece 32 is deflected to guide the water flow in the direction of the spiral blade 21, so that the impact force of the water flow on the spiral blade 21 is more direct, thereby ensuring the impact of the water flow on the bolt blade, and the guiding direction of the umbrella piece 32 on the water flow also avoids the direct impact of the water flow on the water-facing plate 5.

[0029] Figure 7 The figure shows a schematic diagram of the structure of the end of the rotating shaft 2 in a water resource energy recovery device provided by an embodiment of the present invention. Figure 7 In order to facilitate the layout of the power generation equipment, the generator 13 is not coaxially arranged at the end of the rotating shaft 2, so the meshing of gears facilitates the disassembly and installation of the generator 13 and the vertical pipe 1. Specifically: the end of the rotating shaft 2 is coaxially fixed with a driving gear 6, and the end of the rotor of the generator 13 is coaxially fixed with a driven gear 7 meshing with the driving gear 6, thereby realizing the power generation of the generator 13. The generator 13 can also be electrically connected to a battery to store electrical energy.
