DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private power generator for floating objects on the water which is used by suspending it from the floating objects such as ships and buoys that are moored.

[0002]

2. Description of the Related Art In order to secure electricity in a small vessel that stops its engine on the sea and stays for a long time, a private power generator that uses natural energy such as sunlight and wind power is required. As such an in-house power generator, a solar cell which has been put into practical use is considered to be suitable.

[0003]

However, an in-house power generator using a solar cell is expensive and requires a large solar cell panel, which greatly restricts the installation space. Further, when used in a buoy or the like that floats on the sea, a large-sized solar cell panel has a high risk of being damaged due to a collision with a ship or the like, and if it is damaged, the damage is also large. Therefore, it is not suitable as a private power generator for floating objects on the water.

The present invention was devised in view of the above circumstances, and it is a low-priced, small-sized private power generator for a floating object on the water with high power generation efficiency and less risk of damage due to collision with a ship or the like. The purpose is to provide.

[0005]

A private power generator for floating objects on a water according to the present invention is a private power generating apparatus that is used by being suspended from floating objects on the water, and extends radially upward from the center. It is formed between a frame having a plurality of arms having a shape like an umbrella bone of an umbrella suspended in an inverted manner, and a frame in which each tip of the plurality of arms is connected by an annular member, and between the adjacent arms of the frame. Hard to fit into the opening
An elongated fan-shaped member made of a material, open upwards when the frame is lowered to the water, so that the open downwardly when the frame is raised in the water, via a hinge or counterclockwise clockwise each arm piece and supported a plurality of valve plate has, it each arm supporting have each valve plate piece

It has a connecting body that connects the stator to the floating objects on the water so that the distance to the stationary member does not change .

[0006]

When the in-house power generator rises in water due to rocking of floating objects on the water, a plurality of valve plates hingedly connected to the arms of the frame open downward due to water resistance .
On the other hand, if the private power generator descends in the water,
Valve plate opens upward due to water resistance. Where each valve plate

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing an example of an in-house power generator for floating debris according to the present invention, FIG. 2 is a plan view with a valve plate closed, and FIG. 3 is a cross-sectional view for explaining the operation of the valve plate. FIG. 4 is a schematic diagram showing an example of a usage state.

As shown in FIG. 4, the in-house power generator 100 is used by being suspended from an arm 300 projecting outboard from both sides of a floating object 200 such as a surveillance ship.

As shown in FIG. 1 and FIG. 2, this private power generator 100 has a frame 1 that expands upward in a cone shape.
10, a plurality of valve plates 120 arranged in the circumferential direction of the frame 110, a generator 130 attached to the center of the frame 110 also as a weight, and the generator 130 on the arm 300 of the floating object 200. And a connecting body 140 for connection.

The frame 110 has a plurality of arms 111 that extend radially upward from the center and are shaped like umbrellas of an umbrella that is suspended in an inverted manner. Each of the plurality of arms 111 has an annular member 112 whose tip is a pipe.
Is formed, and an elongated fan-shaped opening 113 that widens toward the outer peripheral side is formed between two adjacent arms 111.

The plurality of valve plates 120 are elongated fan-shaped members that fit into the openings 113 formed between two adjacent arms 111 with a slight clearance, and are located on either side of the openings 113 above and below. Arm 1 on one side to be opened
11 is supported on one side by a plurality of hinges 121.
All the valve plates 120 have the same side as a fulcrum, and in the figure, they are arranged in a clockwise direction in a plan view with the fulcrum side as a starting point. As shown in FIG. 3, the opening angle of each valve plate 120 to the upper side is approximately 45 due to the plurality of stoppers 114 attached to the upper surface of the arm 111 on the same side as the hinge 121.
The angle of downward opening is also regulated by about a few degrees, and a plurality of stoppers 115 attached to the lower surface of the arm 111 are also provided.
Is regulated to about 45 degrees.

The generator 130 is of a waterproof type and has a stator 131 having a built-in coil and an annular rotor 132 rotatably supported on the outer peripheral side thereof. Rotor 13
Reference numeral 2 holds a plurality of magnets 133 that allow a magnetic field to pass through the coils inside the stator 131. To the outer peripheral edge portion of the upper end surface of the rotor 132, the respective base ends of the plurality of arms 111 included in the frame 110 are respectively coupled.

The connecting body 140 is, for example, a wire or pipe having a relatively large diameter that does not cause twisting, does not rotate the stator 131 of the generator 130, and keeps the frame 110 completely submerged in water. , Stator 131 floating on the water 2
00 arm 300.

When the water floating object 200 rolls, the two private power generators 100 suspended in water from both sides of the water floating object 200 alternate up and down. When the private power generation device 100 rises, the resistance of water causes the plurality of valve plates 120 to move downward about 45 degrees with the same side as a fulcrum.
Half open at an angle of degrees. As a result, the opening 11
Water passes through 3 from top to bottom, and the water is a half-open valve plate 12
As a half force due to collision with 0, a plurality of valve plates 12
0 is the frame 110 facing toward the hinge 121.
A turning force in the same direction around the center is added. This turning force is transmitted through the frame 110 to the rotor 13 of the generator 130.
2, which is rotated in the circumferential direction. In the figure, the rotation direction is counterclockwise in plan view.

When the private power generator 100 descends, the plurality of valve plates 120 are in a half-opened state at an angle of about 45 degrees upward. As a result, water passes through the openings 113 from the bottom to the top, and the water collides with the half-open valve plates 120, so that a swirling force toward the hinge 121 side is applied to the plurality of valve plates 120. Therefore, also at this time, the generator 13
The zero rotor 132 is rotated in the same direction as when it was raised. It should be noted that the frame 110 and the valve plate 120 have a horn shape that spreads upward as a whole, and the generator 130 attached to the center thereof also serves as a weight.
When 0 is opened, the resistance when descending is small and the floating object 200 floating on the water sinks surely because the floating object 200 tilts. Therefore, the rolling of the floating object 200 floating water is accurately transmitted to the vertical movement of the frame 110.

Thus, as the floating object 200 floating on the water rolls, the private power generator 100 repeatedly moves up and down, whereby the rotor 132 of the generator 130 continues to rotate vigorously. As a result, the rolling energy of the floating object 200 is efficiently converted into electric energy. Generator 1
The electricity generated at 30 is generated by a cable (not shown).
It is supplied to the floating object 200. If the connector 140 is a pipe, a cable can be passed through it.

Further, since the plurality of valve plates 120 are densely arranged in the circumferential direction of the frame 110, the private power generator 100 is smaller than the power generation efficiency, and the general-purpose generator 130 is also used. It is cheap because it uses. Furthermore, since the main part is submerged in water, there is almost no risk of damage due to collision with a ship or the like.

[0018]

As described above, in the case of the private power generation apparatus for floating objects on the water according to the present invention, the power generation with high economical efficiency is performed by utilizing the vertical motion energy due to the rolling of the floating objects on the water. Since a large resistance due to water is used and a plurality of valve plates are densely arranged in the circumferential direction of the frame, high power generation efficiency can be obtained and downsizing can be achieved. The price is reduced because a general-purpose generator is used. Since the main part is submerged in water, there is almost no risk of damage due to collision with a ship, etc. Even if it is damaged, the damage is small and repair is easy.
