Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric boat passage gate device provided in a net place such as a reservoir or a dam.

[0002]

2. Description of the Related Art Currently, in reservoirs, dams, etc., a partition zone called a net field is cut across the water surface and a predetermined depth below the water surface to prevent dust and driftwood from flowing out to the discharge gate side. .

Further, since dust collectors and patrol boats come and go all over the water of the reservoirs and dams, this net place has a ferry gate at the proper place, The gate is designed so that it can be opened and closed when passing by.

Conventionally, as shown in FIG. 7, this passage gate is formed by connecting a kite-shaped gate frame member 81 with a float 82 in the middle of a net place 80 stretched over a reservoir or dam. The door 83 is attached to the empty space of the gate frame member 81 and is suspended by the wire rope 85 operated by the winch 84.

Further, the door 83 is vertically movably inserted into an elevating guide 86 provided in parallel with the gate frame member 81, and closes the gate frame member 81 when rising.
Open when descending.

However, this passage gate has a door 83.
Since the opening and closing operation is performed by vertically moving in the gate frame member 81, the raising and lowering guide 86 is required for the raising and lowering guide of the door 83, which not only makes the structure large, but also this raising and lowering guide. Since 86 requires twice the door length, much material is wasted.

When the door 83 descends, driftwood or the like is likely to be caught between the lower edge of the door 83 and the horizontal frame of the gate frame member 81, and once the driftwood is fitted, the opening / closing operation of the door 83 becomes impossible. , Can not be used.

Further, since the door 83 is constructed so as to be lowered by its own weight, a certain weight is required for its operation. However, if the door 83 is made to be weighed too much, the door 83 is used for feeding out the wire rope 85 by operating the winch 84. Of the wire rope 8
There was the inconvenience of causing irregular winding of No. 5, and it was unavoidable that it was overweight, but if this door 83 is heavy, the winch 8
However, there is a drawback in that the motor is upsized because a large load is applied to the motor.

Further, the winch 84 is one in which both sides of the door 83 are hoisted by two wire ropes 85 by one machine, and one of them is attached to a lifting guide 86 as shown in FIG. Since it is arranged so as to circumnavigate underwater along this, there are many entanglements such as driftwood in this part, which also leads to a cutting accident.

Also, in the replacement work of the wire rope 85, it is necessary to disconnect the passage gate main body from the net 80 and temporarily pull it up to the ground for repair, or to replace it by diving work. Even in the case, it was troublesome and costly.
Etc. had various problems.
