DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing floating dust from rivers provided in an intake channel of a water purification facility.

[0002]

2. Description of the Related Art In order to constantly capture suspended dust near the water surface of a river, a small change in the water level has been made within the range of the intake of the removal device. Each time, the removal device needs to be adjusted up and down by an elevating device, and detailed human and electrical management has been required.

[0003] In addition, if the removal of the removal device is delayed due to some factor at the time of increasing the water, the removal device remains immersed deep in the water, which significantly impedes the flow of water and may cause flooding of the river.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a water level tracking system which can quickly follow a change in water level so as to be always located near a water surface with a lot of floating dust and can efficiently manage the water flow without obstructing flowing water. It is an object of the present invention to provide a floating dust removal device.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a first invention has a length in which one end is pivotally connected to each side of a river and the free end is directed downstream. ,
A short swing arm is provided, and an elevating net catching frame having a net bag for floating dust attached to the free end of the short swing arm is attached in the width direction of the river, between the free ends of the long swing arm. Is provided with a float, and a means for causing the lifting frame to follow the water level in cooperation with the vertical movement of the long swing arm is provided, and a lifting device for the lifting frame is provided. It is a water level tracking type suspended dust removal device for rivers.

According to a second aspect of the present invention, a swing arm having a joint which has one end pivotally attached to each side of the river, the free end of which is directed downstream, and a joint which bends only upward is provided on the way. An ascending / descending net catching frame attached with a trapping bag for floating dust near the joint of the arm is mounted in the width direction of the river, a float is provided between the free ends of each swing arm, and the elevating / descending device for the ascending / descending catching frame is provided. This is a river-water-following type floating dust removal device that is provided.

[0007]

According to the present invention, a removing device can be always installed near the surface of the water with a lot of floating dust, so that it does not sink deeply into the water at the time of increasing the water level and does not hinder the flowing water. The lifting device facilitates quick lifting and maintenance on rivers.

[0008] Further, since the float hinders the capture of dust, the float is provided on the downstream side. However, if the removing device is pulled up on the water channel together with the float, the installation position of the operation table is greatly restricted, and maintenance becomes difficult. Although a large lifting device is required, in the present invention, the float is left on the water surface, and the lifting / lowering catching frame with the catching bag serving as the removing device is structured to be lifted and lowered. This facilitates maintenance and makes the elevating device smaller.

Reference numeral 8 denotes an operation pier installed on the water channel 1 and is provided with a hoisting device 10 (elevating device) for winding up the elevating and catching net frame 6 with a wire 9.

The float 7 of the embodiment is a long swing arm 4
a, 4b are configured to be movable (adjustable) in the direction of flow, and fins 11a are provided on the lower surface to promote buoyancy due to the water flow. A vertical stabilizer 11b is provided at an optimal position to prevent dancing left and right. Further, in order to facilitate lifting and lowering of the lifting and catching frame 6, a balance weight 12 is attached to the short swing arms 3a and 3b.

In this embodiment, a short swing arm 3 as shown in FIG. 4 is used as a means for causing the lifting frame to follow the water level in cooperation with the vertical swing of the long swing arm.
a, 3b are made of angle material and the long swing arms 4a,
4b, the lifting and lowering net frame 6 is configured to follow the water level in conjunction with the vertical movement of the long swing arms 4a, 4b. However, as shown in FIG. , 4
A projecting piece 41 may be provided on the lower surface of b. Also,
In this embodiment, the short swing arm and the long swing arm are pivoted on the same shaft, but the shafts may be different.

With the above-described configuration, the net catching bag 5 automatically follows the area where there is a lot of floating dust (near the water surface) according to the fluctuation of the water level, so that efficient capturing can be performed. Further, even if the lifting of the elevating net catching frame 6 with the net catching bag 5 is delayed at the time of rising water, the frame does not sink deeply into the water, so that flooding of the river can be avoided.

When the net catching bag 5 full of floating dust is replaced, only the lifting net catching frame 6 with the net catching bag 5 is lifted by the hoisting device 10, so that the float 7 is lifted by the hoisting device 10. It can be moved up and down more lightly than when they are integrated.

Furthermore, compared to the case where the float is integrated,
Since the operation pier 8 can be provided in the vicinity of the rising position of the lifting / trapping net capture frame 6, a removing device that can easily replace the trapping net can be provided.

Further, since the float 7 is arranged on the downstream side of the net catching bag 5, the floating dust can be trapped well.
