Description

Technical Field

[0001] This utility model relates to the field of tidal power generation technology, specifically to a marine tidal power generation device. Background Technology

[0002] The working principle of tidal power generation is similar to that of general hydropower generation, which involves building a dam at the estuary or bay to form a natural reservoir, with the turbine generator set installed inside the dam. Because the tidal level difference of seawater is much lower than that of general hydropower stations, tidal power stations should use low-head, high-flow turbine generator sets.

[0003] During power generation, the impeller needs tidal current to drive its rotation. Therefore, the impeller is usually located inside the seawater. When marine organisms (fish) in the seawater approach the impeller, collisions occur, damaging the impeller and injuring the marine organisms. To address this, a marine tidal current power generation device is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] This invention provides a marine tidal power generation device that prevents marine organisms from being drawn into the impeller and causing damage. A cleaning mechanism is installed outside the protective cover. The rotating impeller drives the cleaning mechanism, which moves circumferentially outside the protective cover, preventing the accumulation of marine life and extending the lifespan of the protective cover. Please refer to [link to relevant documentation]. Figures 1-4 It includes: a power generation mechanism 100, a protective cover 200, and a cleaning mechanism 300.

[0030] The power generation mechanism 100 includes a water turbine 110, an impeller 120 and a drive pinion 130. The impeller 120 is mounted on the shaft of the water turbine 110, and the drive pinion 130 is coaxially mounted on the impeller 120.

[0031] Among them, the water turbine 110 is a water turbine generator set. The water turbine 110 is set in the seawater through the connecting frame. The tidal action of the seawater drives the impeller 120 to rotate to provide power for tidal power generation. When the impeller 120 rotates, it synchronously drives the drive pinion 130 to rotate.

[0032] The protective cover 200 is installed on the turbine 110. The protective cover 200 is a spherical cover, and stainless steel protective mesh is installed in all the gaps of the protective cover 200 to prevent marine organisms from entering the interior of the protective cover 200 and to protect the impeller 120.

[0033] The cleaning mechanism 300 is mounted on the protective cover 200. The cleaning mechanism 300 includes a rotating shaft 310, a cleaning gear 320, a transmission component 330, and a cleaning rod 340. The rotating shaft 310 is rotatably connected to the center of the right end of the protective cover 200. The cleaning gear 320 is mounted on the left end of the rotating shaft 310. The transmission component 330 is connected between the drive pinion 130 and the cleaning gear 320. The cleaning rod 340 is mounted on the side wall of the right end of the rotating shaft 310.

[0034] The drive pinion 130 drives the cleaning gear 320 to rotate via the transmission component 330. The cleaning gear 320 drives the cleaning rod 340 to rotate via the rotating shaft 310. The cleaning rod 340 rotates circumferentially outside the protective cover 200 to drive away marine life around the protective cover 200 and scrape off marine life attached to the outer wall of the protective cover 200.

[0035] Specifically, the transmission component 330 includes a transmission gear shaft 331, a transmission pinion 332, and a transmission gear 333. The transmission gear shaft 331 is rotatably connected to the inside of the protective cover 200. The right end of the transmission gear shaft 331 is provided with a transmission pinion 332 that meshes with the cleaning gear 320, and the left end of the transmission gear shaft 331 is provided with a transmission gear 333 that meshes with the drive pinion 130. The diameter of the drive pinion 130 is smaller than the diameter of the transmission gear 333, the diameter of the transmission gear 333 is larger than the diameter of the transmission pinion 332, and the diameter of the transmission pinion 332 is smaller than the diameter of the cleaning gear 320. When the drive pinion 130 and the transmission gear 333, and the transmission pinion 332 and the cleaning gear 320 are in transmission, the small gear drives the large gear, which is a labor-saving transmission and reduces energy loss.

[0036] Since the cleaning rod 340 has a limited range of driving away marine life when it rotates, a rotating ring 350 is provided at the left end of the cleaning rod 340. The rotating ring 350 is rotatably connected to the right end of the casing of the water turbine 110. The right side wall of the rotating ring 350 is provided with evenly distributed protrusions 360. Vibration components 400 are provided on both the front and rear sides of the right end of the casing of the water turbine 110. The vibration component 400 includes a bracket 410, a ram 420 and a return spring 430. The bracket 410 is fixed to the outer wall of the casing of the water turbine 110. The ram 420 is slidably connected to the bracket 410. The return spring 430 is provided between the ram 420 and the bracket 410.

[0037] The vibrating component 400 is located between the protective cover 200 and the cleaning rod 340 to avoid interference between the structures. In the natural state, the left end of the ram 420 faces the protrusion 360. When the protrusion 360 moves in a circular motion, the right end of the protrusion 360 squeezes the ram 420, causing the right end of the ram 420 to touch the protective cover 200. The cleaning rod 340 drives the rotating ring 350 to rotate in a circular motion. When the rotating ring 350 rotates, it simultaneously drives the protrusion 360 to rotate in a circular motion. When the protrusion 360 comes into contact with the ram 420, it squeezes the ram 420, causing the ram 420 to move towards the protective cover 200 and finally strike the protective cover 200 to generate sound, thereby driving away nearby marine life.

[0038] In practical use, the protective cover 200 prevents marine life from entering its interior and protects the impeller 120. The tidal action of the seawater drives the impeller 120 to rotate, providing power for tidal power generation. When the impeller 120 rotates, it synchronously drives the drive pinion 130 to rotate. The drive pinion 130 drives the cleaning gear 320 to rotate through the transmission component 330. The cleaning gear 320 drives the cleaning rod 340 to rotate through the rotating shaft 310. The cleaning rod 340 rotates circumferentially outside the protective cover 200, cleaning the seawater around the protective cover 200. The cleaning rod 340 drives away marine life and scrapes off marine organisms attached to the outer wall of the protective cover 200. At the same time, the cleaning rod 340 drives the rotating ring 350 to rotate in a circle. When the rotating ring 350 rotates, it drives the protrusion 360 to rotate in a circle. When the protrusion 360 comes into contact with the ram 420, it squeezes the ram 420, causing the ram 420 to move towards the protective cover 200. Finally, the ram 420 hits the protective cover 200 and generates a sound, driving away nearby marine life. This protects the protective cover 200 and prevents marine life from being caught in the protective cover 200 and getting injured, thus reducing the impact on the ecosystem.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
