Abstract

PURPOSE:To collect floating dust with good efficiency by laying a separable second netting along the first netting laid traversely in a water channel. CONSTITUTION:A winding winch 4 is operated to send out a wire rope 5, a netting 3 and the rope 5 are tensed by a working ship, etc., the connecting end of the netting 3 and the rope 5 is fixed to the opposite bank, and the netting 3 is extended to the upstream side of the netting 1. When a given amount of floating dust 7 is arrested on the upstream side of the netting 3, a winch 4 is operated to wind up the rope 5 and the netting 3 is pulled to the winch 4 side. When the floating dust 7 is moved to a given place, a crane 6 is operated to lift the dust 7 up to the ground's surface. Since large amounts of floating dust can be collected at a time and moved and lifted to a given place, the efficiency of the dust collecting operation can be raised.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention efficiently removes floating debris on the water surface several times! ? This is about the method I tried several times.

For example, an example of a conventional method for removing floating debris on the surface of a dam lake is explained with reference to Figures 1 and 2.
- A net d with a weight C attached to the lower end is stretched over a float b connected to a rope a to form a net field e, and the net field e is placed upstream of the dam f so as to cross the lake surface. The floating dust Q accumulated on the upstream side of the net field e is surrounded by a net s1 set up before being towed, or it is loaded onto a dust collection boat, or moved to a predetermined position on the lake shore by trolling, and then placed on the lake shore. Floating debris is being lifted to the ground using a crane J installed for lifting it.

However, in any of the above-mentioned conventional dust lifting methods, it is not possible to move a large amount of dust several times at once, and therefore, efficient work cannot be performed.

The present invention has been made for the purpose of eliminating the above-mentioned drawbacks of the conventional means and improving work efficiency by making it possible to remove a large number of pieces of trash several times at once.

Embodiments of the present invention will be described below with reference to the drawings.

A net field 1 consisting of parts similar to those shown in Fig. 1 is connected to a dam 2.
On the upstream side of the net station 1, a net station 3 that can be separated in the longitudinal direction at intervals of about 10 m is installed along the net station 1 so as to cross the lake surface. The wire loaf 5 of the winding winch 4 installed on the lake shore is fixed to one end of the netting station 3, and the crane 6 for lifting floating debris is installed on the same side as the winding winch 4 on the lake shore. Set up Also, 7 in the figure is floating dust.

Next, the operation of the present invention will be explained.

When performing dust suction work on the surface of the dam lake, the winding winch 4 is operated to let out the wire rope 5, and the netting area 3 and the wire row 15 are pulled by an appropriate means such as a work boat, and the connecting end of the wire rope 5 of the netting area 3 is pulled. By fixing it to the opposite shore or at a necessary location, the netting station 3 is stretched upstream of the netting station 1, and the floating debris 7 that has flowed away is retained on the upstream side of the netting station 3 (see Fig. 3).

When the required amount of floating dust 7 has accumulated on the upstream side of the netting field 3, the winding winch 4 is operated to wind up the wire rope 5, and the netting field 3 is drawn toward the winding winch 4 side. Therefore, the floating debris 7 is surrounded by the net yard 3 and moved to the lake shore side where the crane 6 is installed.

Once the floating dust 7 has moved to a predetermined position, the crane 6 is operated to lift the floating dust 7 to the ground. When the floating dust 7 surrounded by the netting field 3 is lifted up by the crane 6 and the floating dust 1 in the working area of the crane 6 is reduced, the wire 0-75 is further wound up and the floating dust 7 is lifted up by the crane 6. Move it to the side and use the crane 6 to lift the dust.

After a predetermined amount of wire 〇-15 has been wound on the winding winch 4, a part of the netting field 3 on the wire row 15 side is separated at a predetermined position so that the winding field 3 is not wound up by the winding winch 4. Then, the tip of the wire rope 5 is fixed to the unremoved net field and dust removal work is performed. In this way, if the net field 3 is successively retracted manually and shortened, the working area will be gradually narrowed,
All floating dust 7 can be removed.

Note that the present invention is not limited to the above-mentioned embodiments.
Of course, various changes can be made without departing from the gist of the present invention.

According to the floating dust acidity method of the present invention, a large amount of floating dust can be produced at once.
Since it becomes possible to acidify the garbage, move it to a predetermined location, and lift up the dust, it can have the excellent effect of improving work efficiency.

Claims (1)

[Claims] 1. A second wJ field that can be separated into predetermined lengths in the longitudinal direction is installed on the upstream side of the first net field, which is stretched across the water surface, to remove floating debris on the upstream side of the second net field. When the floating debris reaches a predetermined amount, pull one end of the second net field to the shore opposite to the one end of the net field and collect the floating debris several times to remove the collected ff floating debris. Lift the dust to the ground using a dust lifting means,
When the amount of floating dust in the working area of the dust removal means decreases, a part of the second m field is sequentially removed to narrow the area surrounded by the second screen field, and the number of floating dust is lifted up. times method.
