The guide rail is used for supporting the weight of the blade plate, is parallelly wound around the rope chain and is matched with the rope chain to work, so that the blade plate is always perpendicular to the horizontal thrust surface when underwater, the distance between the sliding surfaces of the inner ring track and the outer ring track on the lower edge is the same as the distance from the bottom of the upper pulley of the blade plate to the top of the lower pulley, and the blade plate on the lower edge is always perpendicular to the horizontal thrust surface.
Description of the drawings: the energy capture to the morning and evening tides is influenced on the contrary to the too close interval of parallel connection type acanthus leaf, and through many times of experiments, the acanthus leaf interval will be at acanthus leaf height more than 1.5 times efficient, so the chain pitch just must be lengthened a lot, and pitch extension sprocket diameter also correspondingly lengthens, and this is a challenge to marine equipment of volume grow, how to realize both increasing the generated power, becomes the sprocket diameter again, and this is a technological attack. The seawater has high salt content, high corrosion to metal, very high technical requirements on materials of chains, chain link lubrication and the like, and very high cost. The disadvantages of the chain are: the weight of the self-body is heavy; too few sprocket teeth can produce a significant polygon effect, which increases transmission non-uniformity and dynamic load, and aggravates hinge wear. Therefore, the number of teeth of the chain wheel is generally at least 17, and the number of teeth of the chain wheel is at least 25 for the gear with impact force and large impact load. The process of the rope transmission pulley is uniform and smooth, the polygon effect is avoided, and heavy-load transmission cannot be achieved. How to realize that the blade transmission is both even, smooth and easy, again impact resistance power and heavy load transmission, this application adopts rope and sprocket integrated configuration to including supporting pulley just can reach this effect. This application rope chain advantage: the transmission is uniform and smooth, the heavy-duty transmission can be realized, the material dead weight is light, the corrosion resistance is realized, and the structure has no problem that the chain link needs to be lubricated when moving; the rope chain is only responsible for the transmission effect in this application structure, is responsible for the acanthus leaf under the tidal impact force by the guide rail, and steady advancing all the time is perpendicular to the horizontal thrust plane of tide all the time.
