Embodiment Construction

[0022] Such as figure 1 As shown, the full-through-flow shaftless two-way ocean current power generation device includes a manifold 5, a stator 1 and a shaftless impeller rotor 2, both ends of the manifold are bell-shaped, and the stator is cylindrical. The stator is embedded in the middle of the manifold to form a full through flow channel. The confluence pipe is in the shape of a two-way bell mouth, which is suitable for two-way water flow. When it is used as an inlet, it plays the role of converging and increasing the flow velocity. When it is used as an outlet, it plays the role of diffusing and reducing the outlet flow velocity, so that the full-through flow can be achieved. The effect of forming a large front-to-back pressure difference in the channel improves the energy-harvesting efficiency of the shaftless impeller rotor 2 . The shaftless impeller rotor can stably rotate in the stator, the shaftless impeller rotor includes a rim and at least one bidirectional blade, ...

Abstract

The invention discloses a full-cross-flow shaftless bidirectional ocean current power generating device which comprises a collecting pipe, a stator and a shaftless impeller rotor. The two ends of the collecting pipe are each in a horn mouth shape. The stator is in a cylindrical shape. The stator is embedded into the middle of the collecting pipe. The shaftless impeller rotor can stably rotate in the stator. The shaftless impeller rotor comprises a rim and at least one bidirectional blade. The rim is in a cylindrical shape. The bidirectional blade is in an airfoil shape capable of capturing bidirectional water flow energy. The periphery of the bidirectional blade is fixed to the rim. The full-cross-flow shaftless bidirectional ocean current power generating device has the beneficial effects of forming a system on the whole, automatically adapting to bidirectional ocean current power generation, being low in start flow speed and high in protection level, being installed integrally at a time without maintenance, being reliable in operation, supplying direct current power to using equipment directly, and being applied not only in open ocean current, but also in appropriate water flow conditions in river.

Description

technical field [0001] The invention relates to a power generation device, in particular to a power generation device utilizing bidirectional low-speed ocean currents. Background technique [0002] With the development and advancement of the national marine strategy, there is an increasing demand for various marine equipment. Most of the marine equipment with high energy consumption is powered by the near-shore power grid through power cables. However, low-energy marine equipment often has low voltage requirements and low power requirements, so batteries are mostly used for power supply at present. However, this power supply method has a short service life and needs to be replaced regularly, making maintenance difficult and costly. Therefore, at this stage, inventing a simple structure, reliable, low cost, good concealment, and eco-friendly ocean current power generation device is an urgent task to solve the long-term power supply problem of low-energy marine equipment. ...
