Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid power generator for constantly supplying power to a monitoring or observation device installed in the air or mainly in the water or the bottom of the sea or river.

[0002]

2. Description of the Related Art Conventionally, there are power generators installed mainly in the sea or river underwater or on the bottom of a water, in which the direction of the flow is always a constant direction, and a tidal current corresponding to a slowly changing one. It is a large-scale generator, a water flow that takes in a water flow along a predetermined direction into a water channel installed in a certain place, or a rotating bearing with one side fixed to take out electric power is a single bearing It was of a short axis type so as not to cause run-out.

[0003]

The conventional generator has the following disadvantages. (A) Since the fluid does not always follow the direction of the flow of the fluid, the power generation efficiency is very poor depending on the tidal current or the place where the flow is changing. (B) The size of the accessory member for following the flow becomes large, so that miniaturization is difficult. (C) When the power capacity of a generator is increased, the diameter of an armature also increases. When the generator is installed in a flow, it becomes an obstacle to the flow, increases resistance, and causes a problem. (D) Since a bearing is a single bearing, a large-sized, large-power generator cannot generate shaft runout. (E) Since the position of the tip of the coil for generating electricity does not protrude from the center of the shaft, the taking-out of the coil for generating electricity has to be fixed, so that the application scene is limited.

The present invention has been made to eliminate such disadvantages of the prior art, and it is an object of the present invention to always accurately and promptly determine the direction of fluid flow from small to medium sizes. It is an object of the present invention to provide an excellent fluid power generation device that operates at a relatively low cost and has high power generation efficiency.

[0005]

Means for Solving the Problems To achieve the above object, a power generator according to the present invention is provided with a plurality of poles formed on the outer periphery of a hollow shaft in a longitudinal direction parallel to the shaft core. In addition to the fixed shaft, an electric wire from the power generation is drawn through the hollow portion, and a plurality of magnets corresponding to the provided power generation are provided on the inner peripheral wall and one or more sets of propellers or fluid contact plates are fixed to the outer peripheral wall. Alternatively, it is provided via a bearing so as to integrally rotate the outer cylinder.

On the upper side of one end of the hollow shaft, there is sufficient strength to lift and hold the power generating member, and sufficient strength to lift and hold the electric wire swivel or the power generating member having an electrical conduction function while rotating. An electric wire swivel having an electrical conduction function is provided while rotating in conjunction with the swivel having the above, and a swivel is also provided on the lower side which is symmetrical to the electric wire swivel, and is pulled up and down by a chain or the like to be held.

In addition, a direction follower plate which holds both ends of the hollow shaft and which is formed of a rigid vertical plate which penetrates the entire outer periphery of the power generator including the propeller so as to inscribe the same is provided to follow the flow of fluid. A swivel and an electric wire swivel are provided at the left and right ends of the upper surface of the direction follower plate, and a swivel is provided at a lower surface symmetrical to the swivel and the electric wire swivel so as to be pulled up and down by a chain or the like.

In addition, a support member of a hollow body capable of supporting both ends of the hollow shaft and through which electric wires can be routed, and a direction wing fixed or integrated with the support member to follow the flow of the fluid are provided. And a column having a means for freely rotating the above-mentioned constituent members and a wire swivel means therein is provided and held.

In addition, a direction-following cylinder that can be housed in the cylinder while including the outer cylinder of the power generation member and the propeller is provided, and a trumpet-shaped water intake port is connected to an upstream end of the direction-following cylinder, and an outer wall surface is formed. A directional wing is formed in the divergent shape from upstream to downstream, and the hollow shaft is fixedly supported by a generator stay in the cylinder, and an electric wire is connected from the outer end of the trumpet-shaped water inlet to the center of gravity of the generator body. A swivel is provided, and a swivel is provided on the lower outer surface symmetrically to the swivel and pulled up and down by a chain or the like to be held.

Another feature is that horizontal wings are provided which are inclined from the upstream to the rear of the outer cylinder in contact with the flow of the fluid.

[0011] Further, the outer tube or the trumpet-shaped water suction port which is in contact with the flow of the fluid is fixed so as to be rotatable about one end thereof, and a monorail type track is provided on the rotation locus of the other end. is there.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION When using the present invention, a generator having the above-mentioned configuration is connected to a place where a fluid flows, specifically, a place where an ocean current or a tidal current is generated, by a chain or the like via an electric wire swivel and a swivel. Pull up and down, fixed or semi-fixed to the seabed for use. In addition, large or medium-sized ones are rotated by following a flow by using a support or track.

By pulling up and down with the upper electric wire swivel and the lower swivel, the tidal current generator becomes suspended and follows the direction of flow changing with the upper and lower swivel as a fulcrum, while the propeller propels the flow energy. The outer cylinder, which absorbs and inscribes the permanent magnet, sometimes rotates fast and sometimes slowly. As a result, the current generated by the power generation coil flows through the coil of the hollow shaft, passes through the electric wire, passes through the electric wire swivel, and flows to a predetermined external location.

In addition, a small one can generate electric power while following the flow only by the elongated main body cylinder.

According to the present invention, there are the following excellent effects. (B) Since the fluid always follows the flow direction of the fluid, the power generation efficiency is very high depending on the tidal current or the place where the flow is changing. (B) By providing the outer cylinder with a length, the tube itself follows the flow. Therefore, an accessory member for following the flow is not required, and the size is easily reduced. (C) Since the length of the armature is small, the diameter is small, and when the armature is installed in a flow, the resistance to the flow is small and the energy of the fluid can be used relatively effectively. (D) Since the bearings are dual bearings, a large power generator for large power is possible. (E) Since the position of the tip of the coil for generating electricity is protruded from the center of the shaft, the wire for generating coil can be taken out freely, and the application scene becomes wider.
