Description

Technical Field

[0001] This invention relates to the field of power generation equipment, specifically a waterwheel-type power generation device suitable for rapid river environments with drops in elevation. Background Technology

[0002] Currently, many natural environments feature rapid river flows with significant drops in elevation. These rapid currents contain abundant hydropower resources, which are often converted into electricity, greatly facilitating power generation and significantly reducing the cost of power line construction. Existing waterwheel-type power generation equipment converts the kinetic and potential energy of water. However, due to the complex terrain, the waterwheel's installation stability is poor. In practical use, prolonged impacts cause the waterwheel to loosen from its mounting, leading to equipment damage. Therefore, we propose a waterwheel-type power generation device suitable for rapid river flows with significant elevation differences. Summary of the Invention

[0035] In this embodiment, the pressurizing mechanism includes a pressurizing cylinder 31 fixed on the mounting base 8. A piston plate 28 is slidably connected inside the pressurizing cylinder 31. A slide rod 26 is fixed on the upper surface of the piston plate 28. The upper end of the slide rod 26 is connected to the upper end of the pressurizing cylinder 31 through a spring 27.

[0036] In this embodiment, the pressurizing mechanism also includes an air pump 23 fixed on the mounting base 8, and the air pump 23 is connected to the turntable 18 via a pulley assembly 22. A pressurizing cylinder 31 is fixed on the mounting base 8, and the pressurizing cylinder 31 is connected to the air outlet of the air pump 23 via an air pipe 30. A one-way valve 29 is connected to the air pipe 30, and the conduction direction of the one-way valve 29 points to the inside of the pressurizing cylinder 31.

[0037] In this embodiment, the insertion mechanism includes a volute 35 fixed on the mounting base 8. The peripheral wall of the volute 35 is connected to the inside of the booster cylinder 31 through the second air pipe 32. A pressure relief valve 45 is fixed and connected to the side wall of the second air pipe 32. The pressure relief valve 45 is located on one side of the air inlet end of the volute 35. A threaded sleeve 34 is connected through and rotatably to the central axis of the volute 35. Multiple blades 44 are fixed on a section of the peripheral wall of the threaded sleeve 34 inside the volute 35. The multiple blades 44 are evenly spaced along the circumference of the threaded sleeve 34. A screw 33 is threadedly connected to the inner thread of the threaded sleeve 34. An anchor rod 10 is coaxially fixed to the lower end of the screw rod 33. A spirally wound protruding ridge is fixed on the outer peripheral wall of the anchor rod 10.

[0038] Working principle and advantages of this invention: The working process of this waterwheel-type power generation device, suitable for fast-flowing river environments with drops in elevation, is as follows:

[0039] like Figure 1 As shown, the mounting base 8 is fixed to both sides of the channel 9 using anchor bolts 10. The spirally wound protruding ribs on the anchor bolts 10 help improve the stability of the connection between the anchor bolts 10 and the ground on one side of the channel 9. The side structure of the waterwheel 6 is as follows. Figure 2 As shown, the waterwheel 6 rotates under the drive of water flow, causing the waterwheel 6 to drive the multi-faceted rod 4 to rotate through the half-shaft 5 and the coupling. Then, the multi-faceted rod 4 drives the tube shaft 3 to rotate, causing the tube shaft 3 to input power to the speed increaser 2 through the coupling. Under the action of the speed increaser 2, the torque is amplified to drive the generator 1 to work and output electrical energy. The use of the tube shaft 3, multi-faceted rod 4 and two couplings can compensate for the dynamic displacement of the waterwheel 6 under the impact of water flow. This allows the half-shaft 5 to smoothly transmit power even if it is not coaxial with the input shaft of the speed increaser 2, thereby improving the practicality of the entire equipment. Furthermore, the impact damage to the waterwheel 6 will not be transmitted to the speed increaser 2, thereby increasing the service life of the equipment and reducing maintenance costs.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, during the operation of the waterwheel 6, the vibration and impact generated by the waterwheel 6 cause the frame 12 to sway up and down through the half-shaft 5 and the shaft bracket 7. This causes the frame 12 to move the piston plate 14 up and down within the damping cylinder 15 via the slide rod 13. Consequently, the piston plate 14 reciprocates and pressurizes the hydraulic oil within the damping cylinder 15. The pressurized hydraulic oil then compresses the spring 42 via the plunger 43. After the piston plate 14 moves upward, the spring 42's rebound causes the plunger 43 to reset and drives the hydraulic oil to flow within the damping cylinder 15. Thus, the paper resistance inside the hydraulic oil and the reciprocating rebound of the spring 42 dampen and buffer the frame 12 and the waterwheel 6 on it, thereby reducing the impact damage received by the waterwheel 6 and improving the working stability and service life of the waterwheel 6.

[0041] As described above, the frame 12 moves up and down, simultaneously causing the lifting tube 19 to move up and down as well. Figure 4 As shown, when the frame 12 moves the lifting tube 19 upward, the lever 39 moves inward into the lifting tube 19 under the action of the wedge-shaped surface of the wedge block 38 on the turntable 18, compressing the spring 40. This gives the spring 40 a restoring force. When the lever 39 is not in contact with the wedge-shaped surface, the restoring force of the spring 40 causes the lever 39 to return to its original position. Furthermore, when the frame 12 moves the lifting tube 19 downward, the lever 39 engages with the apex of the wedge block 38 and, through the wedge block 38, drives the turntable 18 to... Figure 4 The turntable 18 rotates clockwise. Simultaneously, the inclined surface of the wedge block 38 applies force to the anti-reverse rod 37, causing the anti-reverse rod 37 to move into the anti-reverse tube 16 and compress the spring 36. This gives the spring 36 a restoring force. When the turntable 18 tends to reverse, the restoring force of the spring 36 causes the anti-reverse rod 37 to resist the wedge block 38, thus preventing the turntable 18 from reversing. This achieves unidirectional clockwise rotation of the turntable 18 during the up-and-down reciprocating motion of the frame 12. During the rotation of the turntable 18, the lever 21 rotates synchronously. When the lever 21 contacts the bottom surface of the hammer plate 25, it applies a pushing force to the bottom surface of the hammer plate 25, causing the hammer plate 25 to move upwards on the stand 24 and simultaneously compressing the spring 20. This gives the spring 20 a restoring force, thereby capturing and storing the impact energy received by the waterwheel 6 in the spring 20, further improving the shock absorption and buffering effect of the waterwheel 6.

[0042] As described above, while the turntable 18 rotates, it drives the air pump 23 to work via the pulley assembly 22. The air pump 23 then supplies air into the booster cylinder 31 through the air pipe 30, increasing the air pressure inside the booster cylinder 31 and causing the piston plate 28 to move upwards. This causes the piston plate 28 to stretch the spring 27 via the slide rod 26, giving the spring 27 a restoring force. This utilizes the impact energy received by the waterwheel 6 to compress the air, further capturing energy. The high-pressure air inside the booster cylinder 31 then enters the volute 35 through the air pipe 32. Figure 6 As shown, this causes the blade 44 inside the volute 35 to drive the threaded sleeve 34 in... Figure 6 The screw sleeve 34 has a clockwise rotation tendency, which causes the screw rod 33 to move downward through the threaded transmission. The screw rod 33 then causes the anchor rod 10 to move downward and insert deeper into the stratum. This allows the impact energy received by the waterwheel 6 to drive the anchor rod 10 to fix the mounting base 8 more firmly. This ensures the installation stability of the waterwheel 6 in complex environments, prevents loosening, improves the service life and working efficiency of the equipment, and reduces maintenance costs.

[0043] When lever 21 disengages from hammer plate 25, the restoring force of spring 20 causes hammer plate 25 to move rapidly downward, releasing stored energy. The hammer plate 25 strikes the upper end of slide bar 26, causing slide bar 26 to move piston plate 28 rapidly downward under the restoring force of spring 27. This causes a sharp increase in air pressure in pressurizing cylinder 31, allowing blade 44 to be subjected to greater impact force. Consequently, anchor rod 10 can be further inserted into the formation. When the air pressure in air pipe 32 exceeds the limit, pressure relief valve 45 opens to release pressure, ensuring a stable air pressure in pressurizing cylinder 31. This keeps anchor rod 10 constantly driven by air pressure, allowing it to be promptly inserted downward if loosening occurs between anchor rod 10 and the formation, ensuring the mounting base 8 remains stable.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
