The left and right lifting guides 25a guide the left and right side end portions of the rectangular water control auxiliary gate 25 and the surface portions near the side ends. For example, L-shaped steel is used for the lifting guides 25a.

  The water control auxiliary gate 25 is structured to be lifted and lowered by a gate lifting mechanism (not shown). Examples of the gate lifting mechanism include various mechanisms such as a combination of a wire rope and a cylinder, a combination of a rack girder and a pinion, and a combination of a wire rope and a winding drum.

  Further, for example, a watertight rubber 25b is attached to the peripheral side of the rectangular water control auxiliary gate 25 so that the introduction port 24a is completely closed when the water control auxiliary gate 25 is fully closed, and water leakage does not occur. The water control auxiliary gate 25 when fully closed is watertight by surrounding the outer periphery of the introduction port 24a with the watertight rubber 25b.

Next, the operation based on the configuration of the best mode for carrying out the invention will be described below.
In a state where the gate 21a is erected and closed, the water control auxiliary gate 25 attached to the upstream water channel 22a side of the skin plate 21b of the gate 21a is raised to form a power generation water flow passage formed at the lower part of the skin plate 21b. 24 introduction ports 24a are opened.

  When the introduction port 24a of the power generation running water passage 24 opens, the water in the upstream water channel 22a flows into the power generation running water passage 24 from the introduction port 24a. The inflowed water passes through the power generation running water passage 24 and flows down toward the outlet 24b. A hydroelectric power generation device 23 is attached to the inside of the power generation flow passage 24 close to the outlet 24b, and the propeller 23a of the hydropower generation device 23 is rotated by the flow of water passing through the power generation flow passage 24, so that hydroelectric power generation is performed. The device 23 generates electricity.

  Electricity generated by the hydroelectric generator 23 is transmitted to an external management room, for example, through the power transmission line 23b and used as part of the power source used in the management room. The water obtained by rotating the propeller 23a of the hydroelectric generator 23 is discharged from the outlet 24b of the power generation water passage 24 to the downstream water passage 22b.

In this way, the water that has been unnecessarily discharged from the upstream water channel 22a to the downstream water channel 22b can be converted into electric energy and used, and natural resources can be effectively used.

[Best Mode-4]
Here, FIG. 4 is a side sectional view of the gate with the power generation device.
In FIG. 4, a gate 31 with a power generator is for generating power using running water when water in the upstream water channel 32a of the gate 31a flows out to the downstream water channel 32b. A hydroelectric power generator 33 is attached to the gate 31a. It is constructed so as to block the water channel 32 in the transverse direction with respect to the water channel 32. The gate 31 with a power generator is a undulating gate in which the gate 31a stands up and down from the bottom surface of the water channel 32, and the water channel 32 is opened and closed when the gate 31a rises and falls.

  In the case of natural drainage, the gate 31 with the power generation device allows the gate 31a to fall down and drain the water, or allows the hydraulic power generation device 33 attached to the gate 31a to pass through the gate 31a while the gate 31a is raised and closed. And it has the structure of generating electric power with the flowing flowing water using the hydroelectric generator 33 attached to the gate 31a.

  The gate 31a has a box-like structure having a cavity inside, and the surface thereof is formed of a thin steel plate, and reinforcing ribs are attached to the inner back surface of the thin steel plate in the vertical and horizontal directions. The top 31b of the gate 31a is gently inclined obliquely downward toward the downstream water channel 32b so as to easily overflow.

  A box-shaped gate 31a having a hollow interior has a support shaft 31c fixed to its base end, that is, a lower end when standing, and rotates in the vertical direction around the support shaft 31c in conjunction with the rotation of the support shaft 31c. Move to make an elevation motion.

  The support shaft 31c to which the base end of the gate 31a, that is, the lower end when standing is fixed, is installed in the width direction of the water channel 32, and is installed on the bottom surface of the lower side of the water channel 32 having a step. Both ends of the support shaft 31b are rotatably supported by bearings 31d provided on the left and right side walls of the water channel 32, respectively.

  One end of the support shaft 31c is linked to a drive mechanism installed in an operation chamber (not shown) provided in a side wall of one side of the water channel 32, and the support shaft 31c rotates around the axis by driving of the drive mechanism. Then, the gate 31 with the power generation device is raised and lowered by rotating in the vertical direction around the lower end of the gate 31a.

  Inside the hollow interior of the gate 31a, a water flow passage 34 for power generation is provided in the vertical direction to allow the water in the upstream water channel 2a of the gate 31a to flow out to the downstream water channel 2b. The power generation flowing water passage 34 includes an inlet 34a through which water from the upstream water channel 32a flows and an outlet 34b through which the incoming water flows out to the downstream water channel 32b.

  The introduction port 34a of the power generation running water passage 34 is provided at the top 31b of the gate 31a. The outlet 34b, which is the downstream outlet of the power generation water passage 34, is provided at the lower end of the power generation water passage 34 that is vertically oriented when the gate 31a stands. The outflow port 34b faces the downstream water channel 32b and communicates therewith. The hydroelectric power generation device 33 is attached to the inside of the power generation running water passage 34 between the inlet 34a and the outlet 34b. The hydroelectric generator 33 is attached near the outflow port 34b.

  In the state where the gate 31a is closed, that is, the gate 31a is standing up, the hydroelectric power generation device 33 causes the water in the upstream water passage 32a of the gate 31a to pass through the inside of the power generation flow passage 34 and pass through the inside of the power generation flow passage 34. It has a structure in which power is generated by using running water when falling toward the downstream water channel 32b. The hydroelectric generator 33 is fixed to the inside of the power generation water passage 34 by a plurality of fixing ribs 34 c arranged radially on the inner peripheral surface of the power generation water passage 34.

  As shown in the figure, the hydroelectric generator 33 has a propeller, for example, a propeller 33a attached to a rotary shaft that protrudes upward toward the upstream water channel 32a, that is, when the gate 31a stands up, to the power generation water passage 34 that is directed vertically. A type generator is used.

  The hydroelectric generator 33 is connected to a power transmission line 33b for transmitting the obtained electricity to the outside. The hydroelectric power generation device 33 generates electric power when the propeller 33a rotates due to the flowing water, and is transmitted to an external management room or the like through the power transmission line 33b and used as a part of the power source used in the management room.

Next, the operation based on the configuration of the best mode for carrying out the invention will be described below.
When the water of the upstream water channel 32a is caused to overflow from the top 31b of the gate 31a in a state where the gate 31a is closed, that is, the gate 31a is erected, the overflow water of the upstream water channel 32a is provided at the top 31b of the gate 31a. Then, the gas flows into the power generation water passage 4 provided in the upper part of the gate 31a from the introduction port 34a.

  The inflowing water flows down in the running water passage 34 for power generation. A hydroelectric power generation device 33 is attached to the inside of the power generation running water passage 34 that is vertically directed when the gate 31a is erected, and the hydroelectric power generation device 33 is formed by running water that falls through the power generation water flow passage 4 by flowing water. The propeller 33a rotates and the hydroelectric generator 33 generates power.

  Electricity generated by the hydroelectric generator 33 is transmitted to an external management room, for example, through the power transmission line 33b and used as part of the power source used in the management room. The water obtained by rotating the propeller 33a of the hydroelectric generator 33 is discharged from the outlet 34b of the power generation flow passage 34 to the downstream water passage 32b.

In this way, the water that has been unnecessarily discharged from the upstream water channel 32a to the downstream water channel 32b can be converted into electric energy and used, thereby effectively utilizing natural resources.

  Note that the present invention is not limited to the best mode for carrying out the invention, and various modifications can be made without departing from the spirit of the invention. For example, the propeller type generator has been described as a hydroelectric generator, but the invention is not limited to this. For example, a cross flow generator, a Francis generator, a Pelton generator, a Kaplan generator, etc. May be used. An appropriate model is selected depending on the drop in the installation location and the amount of water. In addition, when the gate width is narrow, one hydroelectric generator is provided at the center, but when the gate width is wide, a plurality of units are provided corresponding to the size of the width.
