Description

Technical Field

[0001] This invention relates to the field of hydropower generation technology, specifically to a small riverside hydropower turbine with a filtration structure for use in canals. Background Technology

[0002] As is well known, hydropower is a clean energy generation method that uses the energy of water flow to drive the rotation of a water turbine, which in turn drives a generator to generate electricity through a transmission system. Depending on the application scenario, its size and operation mode are different, but the basic principle is the same. Permanent magnet synchronous generators or asynchronous generators are commonly used, which are connected to the water turbine through a transmission shaft to convert mechanical speed into electrical energy output.

[0003] While existing technologies offer relatively mature hydroelectric power generation systems, in narrow waterways such as irrigation canals, the limited size and cost of these waterways make it difficult to install large turbines with sophisticated sedimentation or filtration systems. Consequently, silt or vegetation tends to accumulate. Furthermore, these waterways often have small water level differences and lack well-maintained canal slopes, making installation and use difficult. However, in such cases, it is often difficult to connect power to the work area during agricultural irrigation and other production operations, thus the use of hydroelectric turbines remains necessary.

[0004] Based on the problems mentioned above, we found that existing water turbines cannot avoid these problems simultaneously. Even if they can be solved, they require frequent manual maintenance and pose a risk of clogging waterways when not in use. Therefore, we propose a small water turbine with a filtration structure for use along riverbanks. This turbine can be easily installed along riverbanks, can be quickly installed when in use, can be used to accumulate water for power generation, and can be quickly lifted from its occupied position in the riverbank when not in use to avoid the deposition of silt and impurities. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a small-scale water turbine for riverbanks with a filtration structure. It has the advantages of being easy to install along the riverbank, quick to install during use, facilitating power generation by accumulating water levels, and being able to quickly lift off its occupied position in the river when not in use to avoid sediment and impurity deposition.

[0006] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: a small riverside water turbine with a filtration structure, comprising two canal side frames, a suspension beam slidably connected to the outer side of the canal side frame, a riverside frame provided at the bottom of the suspension beam, a power generation device installed on the rear side of the riverside frame, and a soft cofferdam provided on the inner side of the riverside frame. The riprap includes a base plate, an inner sleeve rod at the top of the base plate, an extension rod threaded to the inner side of the inner sleeve rod, a levee corner plate rotatably connected to the left side of the inner sleeve rod and the right side of the extension rod, a pressure beam at the top of the inner sleeve rod, diagonal braces rotatably connected to both sides of the pressure beam, two diagonal braces rotatably connected to two levee corner plates on the side away from the pressure beam, a stabilizing rod fixedly connected to the rear side of the levee corner plate, a stabilizing plate installed on the rear side of the stabilizing rod by bolts, and the inner side of the soft cofferdam being snapped into the stabilizing rod. The power generation device includes a liquid level pan, a water collection pan fixedly connected to the bottom of the liquid level pan, a water inflow pipe fixedly connected to the inner side of the water collection pan, a net fixedly connected to the outer side of the water collection pan, a rotating wheel provided on the inner side of the water collection pan, blades installed on the outer side of the rotating wheel, a frame fixedly connected to the top of the liquid level pan, a power generation device and an energy storage device installed on the top of the frame, a main shaft fixedly connected to the input end of the power generation device, and the outer side of the main shaft fixedly connected to the rotating wheel.

[0007] Using the above technical solution, the canal-side frame is installed on the top of the riverbank using bolts or piles. A suspension beam is used to suspend the structure, allowing it to move vertically along the frame. This allows the bottom structure to be lowered into the riverbed during use or raised when not in use, avoiding siltation caused by constantly occupying the narrow canal. A power generation device is installed to assist in power generation. When the canal-side frame is lowered synchronously, it will impound the connected soft cofferdam within the canal, forming a dam after filling with water to intercept the water flow and increase the height difference. When lowering the canal-side frame, the bottom plate of the frame first contacts the bottom of the canal. Then, according to the width of the canal bottom, the extension rod rotates along the inner sleeve rod, extending through threads to lengthen the total length of the inner sleeve rod and the extension rod, so that the corner plate of the embankment fits against the inner wall of the canal. Then, the pressure beam is pressed vertically downwards, at which point the connected diagonal bracing... The device rotates along the pressure beam and unfolds against the corner plate of the embankment to fit against the inner wall of the canal. At this time, the soft cofferdam connected to it is pulled and unfolded. When the inner wall of the canal is relatively flat, it can fit with a small gap. When used in a canal that has not been fully repaired, it can be embedded in the mud and sand at the edge of the canal to reduce the amount of water flowing through the gap. The filled soft cofferdam intercepts the upstream water flow. After the water collection pan of the power generation device is immersed in the raised water, the water will flow into the inner side of the water collection pan along the water inlet pipe. At the same time, plant tissues and other impurities will be intercepted by the net to avoid clogging the blades and the internal rotating structure. When the water enters the water collection pan along the inclined water inlet pipe, it will drive the blades, the impeller and the main shaft connected to it to rotate. The power generation device generates electricity and stores it through the energy storage device. In agricultural scenarios where it is difficult to supply power, it can be used to power the equipment.

[0008] The invention is further configured such that: a threaded sleeve is fixedly connected to the front side of the pressure beam, a lead screw is threadedly connected to the inner side of the threaded sleeve, an end seat is rotatably connected to the bottom of the lead screw, and the rear side of the end seat is movably connected to the inner sleeve rod.

[0009] By adopting the above technical solution, and by setting a screw sleeve to cooperate with the lead screw, when it is necessary to vertically pull up or press down the pressure beam, the lead screw can be rotated along the end seat. When the lead screw rotates along the screw sleeve, the screw sleeve and the pressure beam will rise and fall vertically, thus providing transmission for structural adjustment.

[0010] The present invention is further configured such that: a ring is rotatably connected to the rear side of the bottom of the end seat, the top of the ring is connected to the end seat by bolts and nuts, and the inner sleeve rod is disposed between the ring and the end seat.

[0011] By adopting the above technical solution, by setting a ring clamp and end seat, the end seat, ring clamp and inner sleeve rod can be unlocked when the inner sleeve rod and extension rod move relative to each other, and after the movement is completed, they can be rotated and locked to the outside of the inner sleeve rod and fixed with bolts, so as to facilitate the adjustment of the structural position as needed.

[0012] The present invention is further configured such that: a connecting frame is fixedly connected to the bottom of the end seat, the bottom of the connecting frame is fixedly connected to the pressure plate, a transmission frame is fixedly connected to the top of the pressure plate, and the top of the transmission frame is fixedly connected to the suspension beam.

[0013] By adopting the above technical solution and setting up a connecting frame, it is easy to connect the end seat and the pressure plate, so as to connect the bottom of the structure and ensure the stability of the transmission and the overall lifting of the structure.

[0014] The invention is further configured such that: a hook is rotatably connected to the outer side of the channel side frame, and the hook is engaged with the suspension beam on the side near the suspension beam.

[0015] By adopting the above technical solution, after the entire structure is lifted from the canal, the hooks can be used to lock the suspension beam to prevent the structure from falling into the canal.

[0016] The invention is further configured such that: a rotating frame is fixedly connected to the front side of each of the two embankment corner plates; a limiting telescopic rod is rotatably connected to the inner side of the left rotating frame; and the right side of the limiting telescopic rod is rotatably connected to the inner side of the right rotating frame.

[0017] By adopting the above technical solution, a rotating frame is set up in conjunction with a limiting telescopic rod. When the two corner plates of the embankment are unfolded, the limiting telescopic rod will also be relatively lengthened and rotate along the rotating frame, which is used to block and limit the front side of the filled soft cofferdam.

[0018] The present invention is further configured such that: a shaft frame is fixedly connected to the bottom of the inner side of the water collection tray, and the inner side of the shaft frame is rotatably connected to the main shaft.

[0019] By adopting the above technical solution, a shaft bracket is set to support the bottom of the main shaft, making its rotation stable, while the water supply can pass through the bottom of the water collection tray.

[0020] The invention is further configured such that: a drain pipe is fixedly connected to the bottom of the water collection tray, and the front side of the drain pipe penetrates through the soft cofferdam and is movably connected to the soft cofferdam, wherein the soft cofferdam is made of PVC coated fabric material.

[0021] By adopting the above technical solution and setting up drainage pipes, it is easy to discharge the water passing through the collection basin to the downstream. The soft cofferdam made of PVC coated fabric has sufficient strength and service life, effectively preventing water leakage, and can also resist wear and erosion in the external environment.

[0022] The present invention is further configured such that a scooping net is fixedly connected to the outside of the water collection plate, and the scooping net is located at the bottom of the barrier net.

[0023] By adopting the above technical solution, and by setting up a net, the water flow and impurities in the water body will be blocked by the net when they are pulled to the outside of the water pipe, and when the entire structure is lifted, they will fall into the net for unified collection and treatment later.

[0024] The present invention is further configured such that: a back frame is fixedly connected to the rear side of the suspension beam, a water drop frame is fixedly connected to the bottom of the back frame, and the inner side of the water drop frame is fixedly connected to the frame.

[0025] By adopting the above technical solution, a back frame is set up in conjunction with a water-drop frame to install the generator frame, so that the power generation unit and the shore frame can be raised and lowered synchronously.

[0026] (III) Beneficial Effects Compared with the prior art, the present invention provides a small riverbank turbine with a filtration structure for use in canals, which has the following beneficial effects: This canal features a small-scale water turbine along its banks, with a filtration structure. The canal-side frame is bolted or piled to the top of the canal bank. A suspension beam suspends the structure, allowing it to move vertically along the frame. This allows the bottom structure to be lowered into the riverbed during use or raised when not in use, preventing siltation caused by constantly occupying narrow canals. A power generation unit is installed to assist in power generation. When the bank frame is lowered synchronously, it traps a connected soft cofferdam within the canal, forming a dam after water is added to intercept the water flow and increase the water level difference. During the lowering of the bank frame, the bottom plate first contacts the canal bottom. Then, based on the width of the canal bottom, the extension rod rotates along the inner sleeve, extending through threads to lengthen the total length of the inner sleeve and extension rod, allowing the embankment plate to adhere to the inner wall of the canal. Then, the pressure beam is pressed vertically downwards, at which point the connected... The connecting diagonal brace rotates along the pressure beam and presses against the corner plate of the embankment to fit against the inner wall of the canal. At this time, the soft cofferdam connected to it is pulled open. When the inner wall of the canal is relatively flat, it can fit with a small gap. When used in a canal that has not been fully repaired, it can be embedded in the mud and sand at the edge of the canal to reduce the amount of water flowing through the gap. The filled soft cofferdam intercepts the upstream water flow. After the water collection pan of the power generation device is immersed in the raised water, the water will flow into the inner side of the water collection pan along the water inlet pipe. At the same time, plant tissues and other impurities will be blocked by the net to avoid clogging the blades and internal rotating structure. When the water enters the water collection pan along the inclined water inlet pipe, it will drive the blades, the impeller and the main shaft connected to it to rotate. After generating electricity through the power generation device, the electricity is stored through the energy storage device. In agricultural scenarios where it is difficult to supply power, it can be used to power the equipment. Attached Figure Description

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1 Please see Figure 1-8 A small riverbank turbine with a filtration structure includes two canal side frames 1, a suspension beam 2 slidably connected to the outer side of the canal side frame 1, a riverbank frame 3 at the bottom of the suspension beam 2, a power generation device 4 installed on the rear side of the riverbank frame 3, and a soft cofferdam 5 installed on the inner side of the riverbank frame 3. The riprap 3 includes a bottom plate 31, with an inner sleeve rod 32 at the top of the bottom plate 31. An extension rod 33 is threadedly connected to the inner side of the inner sleeve rod 32. An embankment corner plate 34 is rotatably connected to the left side of the inner sleeve rod 32 and the right side of the extension rod 33. A pressure beam 35 is provided at the top of the inner sleeve rod 32. Diagonal braces 36 are rotatably connected to both sides of the pressure beam 35. The side of the two diagonal braces 36 away from the pressure beam 35 is rotatably connected to the two embankment corner plates 34. A stabilizing rod 37 is fixedly connected to the rear side of the embankment corner plate 34. A stabilizing plate 38 is installed on the rear side of the stabilizing rod 37 by bolts. The inner side of the soft cofferdam 5 is snapped with the stabilizing rod 37. The canal-side frame 1 is installed on the top of the canal bank using bolts or piles. A suspension beam 2 is used to suspend the structure, allowing it to move vertically along the frame 1. This allows the bottom structure to be lowered into the riverbed during use or raised when not in use, preventing siltation caused by constantly occupying the narrow canal. A power generation device 4 is installed to assist in power generation. When the canal-side frame 3 is lowered simultaneously, it will impound the connected soft cofferdam 5 into the canal, forming a dam after filling with water to intercept the water flow and increase the height difference. When the canal-side frame 3 is lowered, the bottom plate 31 of the frame 3 first contacts the bottom of the canal, and then moves along the width of the canal bottom. The inner sleeve rod 32 rotates the extension rod 33, which extends through the thread and extends the total length of the inner sleeve rod 32 and the extension rod 33, so that the corner plate 34 of the embankment is attached to the inner wall of the canal. Then, the pressure beam 35 is pressed down vertically. At this time, the diagonal brace 36 connected to it will rotate along the pressure beam 35 and press against the corner plate 34 to unfold and attach to the inner wall of the canal. At this time, the soft cofferdam 5 connected to it is pulled and unfolded. When the inner wall of the canal is relatively flat, it can be attached with a small gap. When the canal is not fully repaired, it can be embedded in the mud and sand at the edge of the canal to reduce the amount of water flowing through the gap, and the soft cofferdam 5 after filling intercepts the upstream water flow.

[0031] The front side of the pressure beam 35 is fixedly connected to a threaded sleeve 6, and the inner side of the threaded sleeve 6 is threadedly connected to a lead screw 7. The bottom of the lead screw 7 is rotatably connected to an end seat 8, and the rear side of the end seat 8 is movably connected to the inner sleeve rod 32. By setting the threaded sleeve 6 to cooperate with the lead screw 7, when it is necessary to vertically pull up or press down the pressure beam 35, the lead screw 7 can be rotated along the end seat 8. When the lead screw 7 rotates along the threaded sleeve 6, the threaded sleeve 6 and the pressure beam 35 will rise and fall vertically, providing transmission for structural adjustment. The rear side of the bottom of the end seat 8 is rotatably connected to a ring hoop 9. The top of the ring 9 is connected to the end seat 8 by bolts and nuts. The inner sleeve rod 32 is located between the ring 9 and the end seat 8. By setting the ring 9 to cooperate with the end seat 8, when the inner sleeve rod 32 and the extension rod 33 move relative to each other, the end seat 8, the ring 9, and the inner sleeve rod 32 can be unlocked. After the movement is completed, the end seat 8 is rotated and locked back to the outside of the inner sleeve rod 32 and fixed by bolts, so as to facilitate the adjustment of the structural position as needed. The bottom of the end seat 8 is fixedly connected to the connecting bracket 10, and the bottom of the connecting bracket 10 is fixed to the pressure plate 31. The top of the pressure plate 31 is fixedly connected to a transmission frame 11, and the top of the transmission frame 11 is fixedly connected to the suspension beam 2. By setting the connecting frame 10, it is easy to connect the end seat 8 and the pressure plate 31, so as to facilitate the connection of the bottom of the structure and ensure the stability of the transmission and the overall lifting of the structure. The outer side of the canal side frame 1 is rotatably connected to a hook 12. The side of the hook 12 near the suspension beam 2 is engaged with the suspension beam 2. By setting the hook 12, after the entire structure is lifted out of the canal, it can be lifted through the hook 12. To prevent the suspension beam 2 from falling into the river channel, a rotating frame 13 is fixedly connected to the front of each of the two embankment corner plates 34. A limiting telescopic rod 14 is rotatably connected to the inner side of the left rotating frame 13. The right side of the limiting telescopic rod 14 is rotatably connected to the inner side of the right rotating frame 13. By setting the rotating frame 13 in conjunction with the limiting telescopic rod 14, the limiting telescopic rod 14 will also be relatively lengthened and rotate along the rotating frame 13 when the two embankment corner plates 34 are unfolded, which is used to block and limit the front of the filled soft cofferdam 5.

[0032] The working principle of this embodiment is as follows: In use, the canal side frame 1 is first fixed to the top of the riverbank using bolts or piles. The suspension beam 2 slides vertically down the outside of the canal side frame 1, allowing the bottom structure to enter the river channel. After the pressure plate 31 contacts the bottom of the river channel, the extension rod 33 is rotated along the inner sleeve rod 32 according to the width of the river channel bottom. The total length of the inner sleeve rod 32 and the extension rod 33 is extended through a threaded connection, allowing the embankment corner plate 34 to fit against the inner wall of the river channel. Then, the screw rod 7 is rotated, causing the screw sleeve 6 to press vertically downwards against the pressure beam 35. The diagonal supports 36 on both sides of the pressure beam 35 rotate and press against the embankment corner plate 34 to unfold and fit against the inner wall of the river channel. At this time, the rotating frame 13 on the front side of the embankment corner plate 34 drives the limiting telescopic rod 14 to stretch relative to each other and move along the rotation... The rotating frame 13 blocks and limits the front side of the filled soft cofferdam 5. At the same time, the bottom ring 9 of the end seat 8 is unlocked and adjusted to relock the inner sleeve rod 32. The stabilizing rod 37 and the stabilizing plate 38 are fixed with bolts and then clamped to the soft cofferdam 5 to make it unfold. After filling with water, a dam body is formed to intercept the upstream water flow, raise the water level and increase the drop. When not in use, the suspension beam 2 is raised and fixed by hook 12 to avoid occupying the river channel and causing silt deposition. During the whole process, the pressure beam 35 is raised and lowered through the thread transmission of the screw rod 7 and the screw sleeve 6. The end seat 8 is connected to the pressure plate 31 through the connecting frame 10 and the transmission frame 11 to the suspension beam 2 to ensure the stability of the structural transmission and lifting.

[0033] Example 2 refer to Figure 1-6 A small riverbank water turbine with a filtration structure also includes a power generation device 4. The power generation device 4 includes a liquid level plate 41, a water collection plate 42 fixedly connected to the bottom of the liquid level plate 41, a water inflow pipe 43 fixedly connected to the inner side of the water collection plate 42, a net 44 fixedly connected to the outer side of the water collection plate 42, a rotor 46 provided on the inner side of the water collection plate 42, blades 47 installed on the outer side of the rotor 46, a frame 48 fixedly connected to the top of the liquid level plate 41, a power generation device 4 and an energy storage device installed on the top of the frame 48, a main shaft 45 fixedly connected to the input end of the power generation device 4, and the outer side of the main shaft 45 and the rotor 46 fixedly connected. After the water collection tray 42 of the power generation device 4 is immersed in the raised water, the water will flow into the inner side of the water collection tray 42 along the water inlet pipe 43. At the same time, plant tissues and other impurities will be intercepted by the net 44 to avoid clogging the blades 47 and the internal rotating structure. When the water enters the water collection tray 42 along the inclined water inlet pipe 43, it will drive the blades 47, the rotor 46 and the main shaft 45 connected to it to rotate. The power generation device 4 generates electricity and stores it through the energy storage device. In agricultural scenarios where it is difficult to supply power, it can be used to power the equipment.

[0034] A shaft bracket 15 is fixedly connected to the bottom inner side of the water collection tray 42. The inner side of the shaft bracket 15 is rotatably connected to the main shaft 45. The shaft bracket 15 is used to support the bottom of the main shaft 45, making its rotation stable. At the same time, the water supply can pass through the bottom of the water collection tray 42. A drain pipe 16 is fixedly connected to the bottom of the water collection tray 42. The front side of the drain pipe 16 passes through the flexible cofferdam 5 and is movably connected to the flexible cofferdam 5. The flexible cofferdam 5 is made of PVC coated fabric. By setting up the drain pipe 16, the water passing through the water collection tray 42 can be easily discharged downstream. The flexible cofferdam 5 made of PVC coated fabric has sufficient strength and service life, effectively preventing water leakage. It can also resist wear and erosion in the external environment. A net 17 is fixedly connected to the outside of the water collection plate 42. The net 17 is set at the bottom of the barrier net 44. By setting the net 17, the water flow and impurities in the water body will be blocked by the barrier net 44 when they are pulled to the outside of the water inflow pipe 43. When the entire structure is lifted, they will fall into the net 17 for unified collection and treatment later. A back frame 18 is fixedly connected to the rear side of the suspension beam 2. A water drop frame 19 is fixedly connected to the bottom of the back frame 18. The inner side of the water drop frame 19 is fixedly connected to the frame 48. By setting the back frame 18 in conjunction with the water drop frame 19, the frame 48 can be installed, so that the power generation device 4 and the shore frame 3 can be raised and lowered synchronously.

[0035] The working principle of this embodiment is as follows: When the riprap 3 is lowered, the water collection tray 42 is immersed in the water body after the soft cofferdam 5 is raised. The upstream water flows into the water collection tray 42 at an angle through the inflow pipe 43. The angled design accelerates the water flow to drive the outer blades 47 of the impeller 46 to rotate. The blades 47 drive the main shaft 45 to rotate. The main shaft 45 is supported by the shaft frame 15 to maintain stable rotation, thereby driving the power generation device 4 at the top of the frame 48 to generate electricity. The electrical energy is stored by the energy storage device. The net 44 on the outside of the water collection tray 42 can intercept large particles of impurities such as plant tissue. The bottom net 17 collects sedimented impurities for cleaning when the device is raised. After the water flows through the water collection tray 42, it passes through the bottom drain pipe 16 and flows downstream through the soft cofferdam 5. The back frame 18 on the rear side of the suspension beam 2 is connected to the water drop frame 19 to the frame 48, so that the power generation device 4 rises and falls synchronously with the riprap 3. The soft cofferdam made of coated fabric ensures strength and sealing when blocking water. The entire system achieves continuous power generation and convenient maintenance in river and canal scenarios through water flow drive, filtration and interception, and synchronous lifting design.
