Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wave power generation device that generates an airflow using wave power and rotates a turbine chamber with the airflow to generate electric power.

(Prior Art) Some wave power generation devices include devices that take in and exhaust air using wave fluctuations and convert this suction force and discharge force into rotational force to obtain electric power.

Figure 6 shows a conventional wave power generation device.

In general, the conventional device has a turbine chamber 2 attached to the upper part of an air chamber 1 that communicates with the sea, and a side wall 4 of the turbine chamber 2 equipped with a turbine 3, which covers an intake valve 5 and an exhaust valve 6, and has an air chamber 1 attached thereto. A valve cover 8 is attached to cover the air circulation opening 7 at the upper part of the valve, and a valve cover 13 is attached which covers the intake valve 9 and the exhaust valve 10 and has a ventilation opening 12 that communicates with the atmosphere and has a filter 11 installed therein. It is something.

The exhaust valves 6 and 10 are disposed facing the hole 14 formed in the side wall 4 of the turbine chamber 2 from the outside.
As shown in FIG. 8, the side wall 4 of the turbine chamber 2
A valve fitting 15 is attached to the valve fitting 15, and the valve shaft 16 is rotatably attached via a valve fitting plate 17 to a valve shaft 16 inserted through the valve fitting 15. The valve fitting 15 is fastened to a mounting hole 18 formed in the side wall 4 of the turbine chamber 2 with a bolt 19 . An annular groove 20 is bored around the hole 14, and an annular packing 21 having a semicylindrical cross section is fitted into the groove 20 and bonded. When the valve is in the closed position, it abuts the annular packing 21 in a gas-tight manner. The intake valves 5 and 9 are attached to the inner surface of the side wall of the turbine chamber 2 in a similar structure to the exhaust valves 6 and 10.

When the wave W rises, the air within the air chamber 1 is pushed and moves in the direction of the arrow shown by the solid line. This air pressure opens the intake valve 5, rotates the turbine 3, opens the exhaust valve 10, passes through the filter 11, and escapes to the outside air through the vent 12. Further, when the wave W descends, the pressure inside the air chamber 1 becomes negative, so that air is sucked into the device through the vent 12. In this case, the air moves from the outside air in the direction of the arrow shown by the chain line. Air flowing in through the vent 12 opens the intake valve 9, rotates the turbine, opens the exhaust valve 6, and is sucked into the air chamber 1. In this way, the air flow generated by wave energy flows into the turbine chamber, rotates the turbine 3, and generates electricity.

(Problem to be solved by the invention) However, in conventional equipment, the turbine chamber is installed integrally and the intake valve is configured to be installed on the inner surface of the side wall, so when replacing the intake valve, the valve cover is removed. This intake valve cannot be removed with just the intake valve 5,
9 must have a complicated structure so that it can be removed together with the valve cover. Further, since the annular packing is also adhesively fixed, it cannot be removed well, and cleaning the groove 20 is difficult. In addition, valve mounting bracket 1
Since 5 is made of stainless steel, electrolytic corrosion occurs between it and the side wall of the turbine chamber, which is made of aluminum casting.

Also, in terms of manufacturing, it is difficult to mold the entire turbine chamber in one piece in order to form the groove 20 around the vent 12, so it had to be assembled from a plurality of members. As a result of the above, the number of work processes and costs increase in manufacturing and maintenance.

In view of the above, an object of the present invention is to provide a wave power generation device in which a valve unit that regulates the flow of air in one direction can be installed as an intake valve or an exhaust valve.

(Means for Solving the Problems) In order to achieve the above object, the present invention attaches a valve plate via a valve hinge to a plate-shaped mounting board in which a ventilation hole is formed so as to close the ventilation hole from one side. The valve unit is installed in some of the multiple openings provided in the turbine chamber as an air intake port with the valve plate mounting side facing into the turbine chamber, and the remaining openings are installed as air exhaust ports. It is characterized by being installed with the valve plate mounting side facing outside the turbine room as an outlet. The plate-shaped mounting board has a sandwich structure with an aluminum core and an insulating rubber outer covering.

(Function) Since the present invention is constructed as described above, the valve unit is attached to the opening in the side wall of the turbine chamber from the outside of the side wall, and serves as an intake valve or an exhaust valve depending on the mounting direction. Also, since the mounting board is shielded with insulating rubber, each metal contact can be rotated.

(Example) An example of the present invention will be described based on FIGS. 1 to 5. Wave power generation device 30 shown in FIGS. 1 and 2
The vessel roughly consists of an air chamber 31 that communicates with the sea and a turbine chamber 32 attached to the upper part of the air chamber 31. A plurality of openings 33 are provided in the wall surface 32a of the turbine chamber.
Valve units 36, 37, 38, and 39 each include a plate-shaped mounting board 34 and a valve plate 35 that closes the hole 34a drilled in the mounting board from one side.
It is attached to 3.

The valve unit 36 is installed in an opening 33 in the side wall of the turbine 40 in the turbine chamber with the valve plate 35 facing outward, and the valve unit 37 is installed in the opening 33 in the lower part of the turbine chamber with the valve plate 35 in the opening 33. The valve unit 36 and the valve unit 37 are attached to a valve cover 42 whose lower part communicates with the vent 41 of the air chamber 31.
covered by. The valve unit 38 and the valve unit 39 are similarly attached to the opening 33 in the wall surface 32a of the turbine chamber 32, and are covered by a valve cover 45 having a vent hole 44 with a filter 43 installed in the lower part.

FIG. 3 shows the relationship between the valve unit and the wall surface of the turbine chamber.

is screwed with a bolt 46 so as to tightly close the opening 33.

Figures 4 and 5 show the structure of the valve unit. Neoprene rubber on both sides with aluminum plate material 47 as the core
The mounting board 34 covered with the valve plate 8 has a hole 34a formed in the center, and a periphery 34b of the hole is formed with a step so that the valve plate 35 comes into close contact with the mounting board 34. Further, a plurality of holes 46a are formed at the end of the mounting board 34, aligned with bolt holes 46a formed in the wall surface 32a, and the mounting board 34 is tightly fixed with the bolts 46. The upper side of the valve plate 35 formed of FRP or the like is fixed to the shaft 50 via a fixture 49, and both ends are inserted through stainless steel valve hinges 52 attached to the shaft 50 mounting board 34 via bolts 51, so that it can rotate freely. It is provided. There are pins 53 on both ends of the shaft to prevent it from falling out.
is engaged.

In the wave power generation device 30 with the valve unit attached in this way, when the wave surface W falls, air is sucked in the direction of the chain arrow, and the valve units 36 and 39 open.
The turbine 40 is rotated by the air flowing upward and generates electricity. Further, when the wave surface W rises, the air in the air chamber is pushed out and discharged in the direction of the solid arrow, the valve units 37 and 38 open, and the turbine 40
is rotated by the air flowing upward and generates electricity.
Even if humid air flows in, electrolytic corrosion will not occur because the stainless steel valve hinge 52 is attached to the aluminum plate 47 with the neoprene rubber 48 interposed.

(Effects of the invention) Since the present invention is constructed as described above, the valve unit can be attached to the wall surface of the turbine chamber from the outside from either the front or the back side, making the installation and replacement work easier. At the same time, there is no need to drill a conventional valve packing mounting groove, and the structure of the valve cover can be simplified, resulting in reduced manufacturing costs. Furthermore, electrolytic corrosion due to the material used for the mounting board (aluminum, stainless steel) can be prevented, and the valve plate (valve unit) can be easily replaced at sea. Furthermore, by storing the valve unit as a valve unit, the number of parts is reduced and inventory management is easy.
