[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sludge scraping device for rivers.

[0002]

2. Description of the Related Art In recent years, a large amount of sludge accumulates at the bottom of a river, and at present it is impossible to eliminate such sludge, and this phenomenon has spread to non-urban areas.

[0003] A method of removing this with a sludge scraper is considered. For example, there is a method of coping with a circulation drive system using a chain implemented in a sedimentation basin or the like.
This chain system is composed of a plurality of rotating shafts whose center is oriented in the width direction of the sedimentation basin, sprockets mounted around each rotating shaft, and two right and left chains hung via these sprockets. And The device is
The flight attached to the chain serves as a sludge scraping plate, and is configured to scrape the settled sludge in the direction of the pit and remove the sludge to the outside when the flight comes down. However, when this method is applied to a river as it is, the maintenance cost is too high and the economy is inferior.

On the other hand, in addition to such a circulation system, there is a system in which one scraping plate is linearly reciprocated along a pond bottom. It is long and its lengthwise direction is
Guide member fixed in the moving direction, and the guide member
Operating member reciprocating along
A driving means for moving, and a river width direction from the operating member.
Extending toward both sides, which are the directions, by the operation of the driving means
A rotary support shaft rotatable reciprocally;
Actuate in the direction to rotate downward through the rotating support shaft.
While being ready to sew the sludge settling at the bottom of the river
The rotation of the rotation support shaft by the operation of the driving means in the other direction

And is configured .

[0005]

The present invention is to provide a way, these instrumentation
When applying the system directly to rivers, consider the following:
There is a need. That is, in rivers,
Floods may occur, in which case the installation of a scraping device
Does not lead to flooding of the embankment due to abnormally large water volume
You need to do that. The idea is to install a scraping device.
For rivers that have been carefully considered so as not to cause flooding
An object of the present invention is to provide a sludge scraping device .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. FIG. 1 shows an embodiment of the present invention. In this example, 1 is rivers, although in this embodiment are shown rivers remain natural not intended urban type formed of concrete, of course, also applies to the concrete urban river.

The river 1 is composed of a side part 2 and a bottom part 3. Reference numeral 5 denotes a water surface, and a large number of support members (wooden or steel pile members) 6 are erected on a line at the center between the widths of the river 1 so as to be linear. The supporting member 6 is a river
Extends above the normal water level by a certain amount, and has flanges 7 attached to the upper end of the support member 6, respectively, and the longitudinal direction is directed to the flow direction of the river 1 through these flanges 7 °. A monorail type guide member 8 is fixed. The guide member 8 is made of H-shaped steel.

The guide member 8 has a saddle mounted state thereon.
Ru actuating member 10 Na in the upper plate portion and the left and right side plate portions is provided so as, so as to reciprocate back and forth by a plurality of rollers 11 ‥‥ the top and sides.

On the upper side of the upper plate portion of the operating member 10, two brackets 12 on the left and right sides are fixed.
The rotation support shaft 13 is provided rotatably back and forth via the. The rotation support shaft 13 has a projecting piece 14 at a central position thereof, and a wire 15 is hung on the projecting piece 14.

This wire 15 is one of the driving means,
Driving the wire 15 is a drive source and a sprocket, not shown. When the wire 15 is pulled in the flow direction of the river 1, the protruding piece 14 is also pulled in the same direction, and the rotary support shaft 1 is pulled.
When the scraping plate (scraping member) 17 attached to 3 engages with the stopper 18, it becomes a vertical posture (scraping posture) ,
While advancing in the downstream direction while pulling the sludge at the bottom of the river, the wire 15 is pulled in the opposite direction, so that
Is tilted in the downstream direction of the river from the vertical posture to avoid the river bottom (avoidance posture) , and the scraping plate 17 is pulled back in the upstream direction without any change. Thus, the scraping plate 17 reciprocates periodically.

Although the support member 6 has a pillar shape, it may have a plate shape such as a sheet pile. The guide member 8 is made of H-shaped steel, but may be made of reinforced concrete. Further, the guide member 8 may be a link type. Moreover, raking plates 17 may be a mesh, further, the raking plates 17, as shown in FIG. 3, but it may also be constituted only or the entire bottom of an elastic member. Thing these is the same for the embodiment shown in the following Figure 2.

FIG. 2 shows another embodiment. In this embodiment, reference numeral 20 denotes a gantry to which the support member 6 is fixed via the gantry 20. The gantry 20 is, for example,
It may be long, such as extending between the two support members 6,6. Other configurations are the same as those of the above embodiment.

FIG. 3 shows an additional example. This example is for a reservoir, not a river.
The entire device is all submerged below the water surface 30, and the device has a circular pit 32 embedded in the bottom center of the reservoir 31;
And a submersible pump 33 provided therein. Sludge is drawn into the pit 32.

A rotating shaft 34 rises in the pit 32,
The rotating body 35 is attached to the upper end of the coaxial 34, and a scraping plate 36 extends around the rotating body 35. The scraping plate 36 is provided with a rubber plate 37 at a lower portion so as to easily follow the pond bottom.

The rotating shaft 34 is driven by an underwater motor (not shown).
Rotates, and the rotating body 35 also rotates, and the scraping plate 36 continues to rotate in the direction of the arrow or in the opposite direction. Thereby, the sludge at the bottom of the pond is attracted into the pit 32, and the sludge is removed by the submersible pump 33 and the piping (not shown).
