Abstract

PROBLEM TO BE SOLVED: To solve the problems that there are considerable drawbacks in an actuation moving mechanism and a protection device of a conventional hydraulic power generating device, installation is likely to be limited due to installation environments such as water current quality such as a flow rate or a water depth, and a river width or a shape of a river bank, and there are also drawbacks in dealing with rapid change of the flow rate.SOLUTION: A system it adopted, in which a power generation mechanism portion is always above the water. A movable structure of a unit type integrated with the power generation mechanism portion is provided, and is easily installed at an arbitrarily suitable place irrespective of the water current quality or installation environments. This unit form allows a plurality of units to be relatively easily installed in parallel in conformity with the river width, or in series along the water current, or in a diagonal row as required. Further, the constraints on the installation conditions due to the conditions such as the water current quality or a river and the river bank shape and environments are suppressed to the minimum level. Further, it is devised so that it is durable against rapid change in the water current to the utmost. Further, in accordance with the system, the change of the installation place, movement, or restitution is relatively easily performed.

Description

    The present invention is a small and medium-sized hydroelectric generator installed in a river, a water channel, or the like.

  There is a system in which a large number of propellers are attached to a single shaft in a skewer shape, and the power is generated by floating and rotating in a flow. (For example, JP 59-180070)

  There is a system in which a turbine generator is floated on a river and the power is generated at a constant flow rate. (For example, Japanese Patent Laid-Open No. 60-132078)

  JP 59-180070   JP 60-1332078

  The contents of Patent Documents 1 and 2 are likely to be limited to installation environments such as water flow, river width, and riverbank shape. Structurally, if the main part of the operating mechanism is in the water, the operating mechanism and the protective device are quite difficult. In addition, there are problems such as the loss of water due to a sudden increase in water due to heavy rain and the destruction of the device against obstacles such as driftwood and driftstone.

  The present invention is intended to solve the problems of such conventional methods and configurations, and minimizes restrictions on installation conditions depending on conditions such as the nature of the water flow, the shape of the river, and the environment. It is about to try.

  In order to achieve the above object, the present invention provides an attached movable structure to which a protective device and a flow rate increasing device are attached, and is a unit type integrated with the power generation device portion. Also, it should be easy to install in any place regardless of the installation environment. This unit makes it easy to install multiple units in parallel to the river width, in series along the water stream, or in a diagonal row as needed.

As an influential element of this method, the appropriate selection of the place where the unit is installed and the method of arrangement of the units, the irregular fluctuations of water flow seen in the curved part of the river and the damage and damage to the riverbank and embankment due to the concentrated water flow It can be applied as a preventive device such as breakage or a shock absorber.
In addition, to reduce the adverse effects on river structures such as bridges and revetment structures caused by the enlargement of Nakashu, for example, due to destructive force due to water increase during the snowmelt season, sudden increase / decrease or change in water flow during heavy rain and typhoon Can also be used.

  Furthermore, since this system also functions in the same manner as a head weir, it is possible to cut and install a part of an existing head weir according to the width of the unit. In addition, if units are installed in parallel with the river width, it can be used as a head weir, and the construction cost of a new head weir can be eliminated or greatly reduced.

  As described above, the hydraulic power generation apparatus of the present invention pursues the simplicity of the structure of the apparatus main body and ease of installation, and has a public property that is also useful for protecting various structures related to the river environment and rivers and waterways. Can be provided as

  In addition, the power generation according to the present invention can be utilized as one of the main elements of a power source using natural energy of the “smart clad system” which is said to be the latest technology of a power network system.

  Overall view of a hydroelectric generator showing an embodiment of the present invention (section AA in FIG. 2)   Top view of the hydroelectric generator

      Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

  In the figure, the pedestal (1) which forms the main body of the unit is installed at an appropriate place such as a river and a water channel. On the water inlet side of the gantry, there is an inclined wire net-like obstacle removing cover (9) for removing various obstacles such as driftwood flowing down with running water. Further, a water flow adjusting plate (10) for increasing the flow velocity is attached to the inside of the gantry. Each corner at the lowermost corner of the gantry is a claw claw (11 for firmly fixing the gantry to the river bed. ) Is attached.

  This gantry (1) has a necessary and sufficient weight so that it does not move easily due to increase / decrease or sudden change of the water flow, and the vector amount (acting force) generated by the water flow and water pressure applied to the water flow adjusting plate (10). ) Acts to push the frame and biting claw (11) toward the riverbed.

  The float arm (3) pivots about the fulcrum shaft (2), and the power shaft (4), the water wheel (5), the generator (6), and the speed increaser (7) integrated therewith. Together with the float drum (8), it automatically goes up and down according to the change of the water level.

  A turbine (5), a generator (6), and a speed increaser (7) are attached to the power shaft (4).

  The float drum (8) attached to the tip of the float arm (3) maintains the necessary and sufficient buoyancy calculated from the total weight of all the parts attached to the power shaft (4). Is calculated as follows.
