Description

[Detailed description of the invention] This invention relates to a dust removal device installed in a cylinder gate that takes in surface water from a reservoir.

There is an idea described in Japanese Utility Model Publication No. 43-3483 in which a dust removal screen is provided on the cylinder gate.

In this known device, small floats are attached to a plurality of pillars surrounding a cylinder gate so that they can rise and fall freely, and a dust removal screen such as a wire mesh is attached between each float, so that floating dust near the water surface is removed by the screen. .

However, since the dust that adheres to the dust removal sufunone must be removed manually, there is a problem in that it is time consuming.

This device differs from the above-mentioned known dust remover in that the screen can be hoisted up by a lifting machine on the water intake tower, and the dust removal packet installed at the bottom of the screen is guided by a guide rail. To provide a dust removal device which turns the packets which are oriented diagonally upward when they are lifted up and when the upper limit is reached, turns them diagonally downward and discharges the garbage onto a stick provided on the outside of the upper part of a water intake tower.

The details of this invention will be explained below based on the attached drawings.

In FIG. 1, 1 is a dam constituting a reservoir, and 2 is a plurality of supports of a water intake tower B provided inside the dam 1.

A is a cylinder gate, which has multiple sliding tubes 3 with different large and small diameters.
It is made expandable and retractable by fitting them together.

Reference numeral 4 denotes an operation room installed in the upper part of the water intake tower B, and a lifting beam 6 is suspended by a rope 5 hanging from a lifting machine in this room 4. The outer flange of the water intake provided in
A float 8 located above the water intake is also attached.

Numeral 9 is a float that moves up and down along each support column 2, and both ends of a dust removal screen 10 are fixed to each float 9.

This dust removal screen 10 is made up of a plurality of vertical rods and horizontal rods, and a horizontal tube 11 is fixed to the lower end thereof.

Reference numeral 12 denotes a rotating shaft rotatably inserted into the cylinder 11, both ends of which protrude from both ends of the cylinder 11, and the left and right frames of the dust scraping packet 13 are fixed to these protruding parts.

This packet 13 has a lattice shape as shown in FIG.
The center of gravity of the packet 13 including the arm 14 and the roller 15 is set outward from the shaft 11 in order to make contact with the shaft 11 .

The upper end of the guide rail 16 forms an inclined part 17 which is slightly inclined rearward as shown in FIG. will be established.

Reference numeral 19 denotes a pole installed so as to surround the upper part of the water intake tower B, that is, the right place on the water surface, and is located below the outer side of the packet 13 which is oriented diagonally downward as shown in Fig. 5.
to receive the garbage discharged from the

Reference numeral 20 in FIG. 5 is a rope for hoisting the dust removal screen 10.

This rope 20 is wrapped several times around a drum in the operating room and then suspended over the lifting beam 6. A link that also serves as a weight is fixed to the lower end of this hanging rope 20, and this link is pulled to the hook of the lifting beam 6. When the lifting beam 6 is lowered, the dust removal screen 10 is pulled up by the rope 20.

However, it goes without saying that the dust removal screen 10 may be directly rolled up by a lifting machine provided in the operation room 4.

This device has the above-mentioned structure, and the normal water intake state is as shown in Fig. 1, when cylinder game A is in full state, and the water intake port at the upper end of the uppermost sliding tube 3 is slightly below the water surface. Since the upper end of the dust removal screen 10 is slightly projected above the water surface by the float 9, the dust floating on the water surface is blocked by the screen 10, and only the surface layer flows into the cylinder game A from the water intake.

In this state, even if the water surface changes somewhat, the relationship between the screen 10 and the water surface does not change because the float 9 follows the water surface.

Furthermore, the water intake of the cylinder game A can also be made to follow the water surface by operating the lifting beam 6.

Next, when pulling up the packet 13, the water intake is temporarily stopped, the cylinder game A is hoisted up by the raising machine installed in the operation room 4, and the rope 20 hanging from the operation room 4 is fully retracted.
After engaging the link at the lower end of the lifting beam 6 with the hook of the lifting beam 6, the lifting machine of the cylinder gate 1-A is rewound and the lifting beam 6 is lowered together with the cylinder gate A which is still in the fully retracted state. The dust removal screen 10 is moved by the float 9 and the packet 13 due to its own weight.
are both raised.

When the thus lifted packet 13 emerges from the water surface, the dust floating near the screen 10 is stirred up.

At this time, the packet 13 is oriented diagonally upward as shown in FIG. 4, and no garbage falls out.

When the packet 13 further rises and reaches the top of the table 9, the rollers 15 on both sides of the packet 13 enter the inclined portion 17 as shown in FIG. 5, causing the packet 13 to tilt downward under its own weight.

Therefore, the garbage on the packet 13 is discharged onto the deck 19.

When the dust removal is completed and the dust removal screen 10 is lowered, the fully retracted cylinder cage 1-A is lowered.
It is good to raise it.

Further, the garbage discharged onto the deck 19 as described above is appropriately collected and removed using a work tool or the like.

As mentioned above, this device is equipped with a rotatable dust scraping packet at the bottom of the dust removal screen attached to a float that moves up and down along the support of the water intake tower, so that a large amount of dust collected on the outside of the dust removal screen can be collected by the packet. Furthermore, the attitude of the packet changes from diagonally upward while rising to diagonally downward at the upper limit, and while it does not spill dust while rising, it discharges the dust onto the deck at the upper limit, making it extremely easy and safe to remove dust. It will be held in

In addition, since the dust removal operation is performed using a packet by simply pulling up the dust removal screen, the operation is extremely easy.
