Description

  The present invention relates to an installation structure of a hydroelectric power generation apparatus that obtains hydroelectric power generation using the water flow of the sea or river.

  When power generation is performed with the energy of a water stream flowing in the sea or river, the installation location of the hydroelectric generator becomes a problem. When a hydroelectric generator is installed on the surface of water with a strong flow velocity, the surface of the water obstructs water traffic such as a ship, and it is often difficult to install the hydroelectric generator. If a hydroelectric generator is installed at the bottom of the water, the flow velocity is slow and there is a lot of dust, which is inconvenient for the hydroelectric generator.

  Therefore, it is optimal to install the hydroelectric generator in the sea or underwater that has a certain flow velocity and does not hinder water traffic, and has little dust. Conventionally, Patent Document 1 is cited as an example in which a hydroelectric generator is installed in the sea. Various types of hydroelectric generators have been proposed. For example, there are Patent Documents 2 and 3 listed below.

  Patent Document 1 has a structure shown in FIGS. A floating body B having a conduit A and a generator C facing a flow is moored at a predetermined depth by a mooring line 9 and a anchor 10 from a bow to a sea current having a stable flow velocity and direction. Floating body B has a water intake 1 on the entire bow, and the cross section perpendicular to the ocean current at the center of conduit A that connects water intake 1 to which water turbine 6 is mounted and stern discharge 2 is the same as that of water intake 1. It is formed in a circular shape compressed to a few tenths of the area. As a result, since the flow velocity of the seawater at the position of the water turbine 6 is accelerated to several tens of times the flow velocity of the ocean current at the intake port 1, a large amount of power can be obtained by utilizing ocean current energy. Thereby, the ocean current energy flowing in the conduit A is converted into electric energy by the water turbine 6 and the generator C, and is transmitted to the land by the submarine power transmission line 7.

  In order to keep the floating body B horizontal, the water injection amount of the air tank 3 close to the stern of the air tank 3 divided into the front, rear, left, and right and up and down is adjusted. In addition, the rudder 4 is provided on the upper, lower, left, and right sides of the stern, and the posture of the floating body B is maintained by making the water intake 1 on the bow face the ocean current.

  In Patent Document 1, in order to maintain the posture of the floating body B horizontally, the amount of water injected into the plurality of air tanks 3 is adjusted and a rudder 4 is provided. However, when the floating body B is small, the floating body B easily rotates and moves up and down, left and right in a water flow, and it is difficult to keep the posture horizontal. For this reason, the floating body B must be enlarged. Further, since the generator C and the floating body B are integrated, there is a problem that not only the ocean current power generation submarine (hydroelectric power generation device) becomes large, but also the cost for each hydroelectric power generation device becomes too high.

  Moreover, in order to balance with respect to a water flow, it is necessary to make it a blow-off shape with respect to the water intake. For this reason, it becomes a tunnel-like conduit A (water channel) that is very long with respect to the direction of water flow. Almost no water flows into such a long tunnel-shaped conduit A.

  A first object of the present invention is to provide an economical installation structure of a hydroelectric power generation apparatus that can efficiently generate a large amount of power without increasing the size of the hydroelectric power generation apparatus.

The other end is fixed to the hook or the weight of the lower part of the wire, one end is fixed to both sides above the front part of the power generator housing frame, and the other end is fixed to the middle of the wire. It consists of an upper wire.

  According to a fifth aspect of the present invention for solving the first to third problems, in the first, second, or third aspect, the wire has one end fixed to both sides below the front portion of the power generation device housing frame. The other end is made of a wire fixed to the hook or the weight, and the buoyancy tank in the rear part is formed to have a larger buoyancy than the buoyancy tank in the front part.

  A sixth aspect of the present invention for solving the first to third problems is that, in the first, second, or third aspect, the wire has one end at a substantially central portion on both sides of the bottom plate of the power generation device housing frame. The other end is made of a wire fixed to the flange or the weight, and a weight is fixed to the lower part of the front portion of the power generation device housing frame.

  A first embodiment of the installation structure of the hydroelectric generator of the present invention will be described with reference to FIGS. In the present embodiment, a power generator housing frame 30 shown in FIG. 6 is used. The power generation device storage frame 30 can store a plurality of (six in the embodiment) hydropower generation devices 20 in parallel from above. On the front part and the rear part of the horizontally long bottom plate 31, lower part setting plates 32, 33 that restrict the front-rear direction of the lower part of the hydroelectric generator 20 are fixed. On the sides 32 and 33, side plates 34 and 34 having four corners cut into a rectangular shape are fixed. On the front part and the rear part of the side plates 34, 34, upper part setting plates 35, 36 that restrict the front-rear direction of the upper part of the hydroelectric generator 20 are fixed. The bottom plate 31, the side plates 34 and 34, the lower portion setting plates 32 and 33, and the upper portion setting plates 35 and 36 form a structure in which the upper side is opened and the front and rear sides are opened in a horizontally long rectangular shape. The side plates 34, 34 are partitioned by five partition plates 37, 37,... Fixed on the bottom plate 31, and six power generation device storage portions 38, 38,. Thereby, six flowing water inlet side windows 39, 39 ... are formed on the front side, and the flowing water outlet side windows 40, 40,... Correspond to the flowing water inlet side windows 39, 39 ... on the rear side. -Is formed.

  Buoyancy tanks 45, 46 filled with air or gas are fixed to the upper part regulating plate 35 above the front part and the upper part regulating plate 36 above the rear part of the power generator housing frame 30. Here, the buoyancy tanks 45 and 46 store the hydroelectric generator 20 in the power generator storage portions 38, 38... Of the power generator storage frame 30 and put the power generator storage frame 30 into the sea or water. It has a buoyancy that does not sink to the bottom of the sea or river.

  As shown in FIG. 1, wire fittings 50, 50 and 51, 51 are fixed to the side below the front part and the side above the front part of the power generation device storage frame 30, and the wire fittings 50, 50 are fixed. One end of the wires 52, 52 is fixed, and the other end of the wires 52, 52 is attached to a wire winder 54, 54 fixed to a rod or weight 53, 53. Wire attachments 55 and 55 are fixed in the middle of the wires 52 and 52, and wires 56 and 56 are fixed to the wire attachments 51, 51 and 55, 55. Here, in the state where the dredging or weights 53, 53 are installed on the seabed or the riverbed and the hydroelectric generator 20 is housed in the power generator housings 38, 38. , 56 are formed in such a length that the front surface portion of the power generator housing frame 30 is substantially vertical, that is, the flow channel inlet of the hydroelectric generator 20 is horizontal. Wire attachments 63, 63 are fixed to the side below the rear part of the power generation device storage frame 30, and one ends of the wires 64, 64 are fixed to the wire attachments 63, 63. The end is fixed to a hook or weight 65, 65.

  Next, the operation will be described. The hydroelectric generator 20 is housed in the power generator housings 38, 38... So that the flow channel inlet of the hydropower generator 20 faces the running water inlet side windows 39, 39... From above the power generator housing frame 30. . Further, in a shallow sea or river that is relatively close to the quay, the dredging or weights 53, 53 are arranged so that the flowing water inlet side windows 39, 39,... Of the power generator housing frame 30 face the water flow direction F. Install on the bottom of the sea or river. Therefore, the lengths of the wires 52, 52 are adjusted by winding or loosening the wires 52, 52 with the wire winders 54, 54, so that the power generator housing frame 30 has a depth that does not hinder sea or water traffic. Install it at the earliest location in the water stream.

  Thus, since the several hydroelectric generator 20 is accommodated in parallel in the electric power generating apparatus accommodation frame 30, the hydroelectric generator 20 may be small. Further, since the power generation device storage frame 30 in which a plurality of hydroelectric power generation devices 20 are stored is large, the posture can be maintained horizontally. Moreover, since a plurality of hydroelectric generators 20 are housed, a large amount of power generation can be obtained efficiently.

  In addition, since the plurality of hydroelectric generators 20 are accommodated in parallel in the power generator housing frame 30, the hydroelectric generator 20 having a shortened water channel is balanced at a right angle to the water flow and the power generator housing frame 30 is used. Can be installed. Although the hydroelectric generator 20 and the generator may be integrated, since the generator housing frame 30 is provided with a plurality of generator housing parts 38, 38... Separately, some of the power generation device storage portions 38, 38,... This is economical because it is not necessary to provide a generator for each of the hydroelectric generators 20.

  Since the power generation device storage frame 30 is provided with buoyancy tanks 45 and 46 above the front portion and the rear portion, even if a plurality of hydraulic power generation devices 20 are stored in the power generation device storage frame 30, the power generation device The storage frame 30 can be installed in the sea or underwater. Further, the moment when the power generation device housing frame 30 tries to rotate in the direction of arrow G due to the pressure of the fluid in the water flow direction F is prevented by the tension of the wires 52, 52, 56, and 56 attached to the power generation device housing frame 30. Then, the flow channel entrance of the hydroelectric generator 20 is adjusted to be substantially horizontal. The wires 64 and 64 and the hooks or weights 65 and 65 are not particularly provided. However, if the wires 64 and 64 and the hooks or weights 65 and 65 are provided, the rear portion of the power generation device housing frame 30 may fluctuate. And the position is stable.

  Since the upper portions of the power generation device storage portions 38, 38... Of the power generation device storage frame 30 are open, for example, by attaching a hook metal fitting to the upper surface of the hydroelectric power generation device 20, maintenance of the hydroelectric power generation device 20 can be performed. When necessary, it can be lifted with a crane and transported to the ground from the sea or river for maintenance, and can be easily maintained.
