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.

It is well known that a cylinder gate is equipped with a dust removal screen, but this known dust removal screen has a dust removal screen such as a metal mesh installed between small floats that can be raised and lowered and attached to a plurality of pillars surrounding the cylinder gate. Floating dust is removed by this screen.

However, this known dust removal screen has the disadvantage that it is time consuming because the dust adhering to the screen must be removed manually.

This invention differs from the known dust remover as described above, in that an elevating frame is provided by a hoist on the dust removal screen 1, which is made up of a large number of vertical rods provided on each side of a conventional water intake tower, and this elevating frame is A claw is provided to scrape off the dust caught between the vertical bars of the dust removal screen, and a packet is provided to receive the dirt scraped off by the claw. To provide a dust removal device capable of removing dust caught in a dust removal screen and dust washed up on the outside of a dust removal screen.

Embodiments of this invention will be described in detail below with reference to the accompanying 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 body, which is made expandable and retractable by fitting a plurality of sliding tubes 3 of different diameters together.

Reference numeral 4 denotes an operation room installed at the top of the water intake tower B. A lifting beam 6 is suspended by a rope 5 hanging from a hoisting machine in this room 4. The flange of the water intake provided at the upper end is fixed via a tension rod 7, and this tension rod 7
A float 8 located above the water intake is also attached.

D is a dust removal screen consisting of a large number of vertical rods 9 arranged at regular intervals between the pillars 2, and a lifting frame E with a float is provided on the outside thereof.

As shown in FIG. 3, the above-mentioned elevating frame E is constructed by connecting the frames 11 of the left and right floats 10 with a plurality of horizontal rods 12, and both ends of a shaft 13 are fixed to the lower portions of the left and right frames 11.

Ring-shaped portions 15 at the rear of both ends of the packet 14 are rotatably fitted near both ends of the shaft 13, so that the packet 14 rotates around the shaft 13.

This packet 14 is made of a grid-like frame covered with punched metal.

are in contact with each other so that the elevator frame E vertically moves up and down along each surface of the water intake tower B.

Arms 21 facing backward are fixed to both ends of the packet 14,
A roller 22 at the end of this arm 21 contacts the front surface of a guide rail 23 fixed to both sides of the front surface of each screen D.

The upper end of this guide rail 23 becomes an inclined part 24 which is slightly inclined rearward as shown in FIGS. 6 and 7, and a stopper 25 is provided at the upper end.

Furthermore, notches are provided at both ends of the cylinder 16, and a pair of stoppers 26 are provided on the shaft 13 through these notches to limit the range of swing of the claws 17.

Reference numeral 27 in FIGS. 2 and 3 indicates a pair of left and right ropes that lift the lifting frame E, and these ropes 27 are wound up by a winding drum 29 on a deck 28 as shown in FIG. .

This drum 29 is driven by an electric drive device or a handle (not shown).

In FIGS. 5 to 7, reference numeral 30 denotes a movable locking lever that is swingably attached to the side surface of each frame 11 by a shaft 31. On the lower side of this lever 30, there is a movable locking lever 30 that is attached to the side of each frame 11 so as to be able to swing freely. Engagement notches 33 are provided in which the pins 32 at both ends engage, and a pair of upper and lower stoppers 34 are provided on the sides of the frame 11 to limit the upper and lower limits of the lever 30.

Further, a downward connecting rod 35 is connected to the outer end of the lever 30, and a float 36 is fixed to the lower end thereof.

This link 35 is designed to be able to swing within a small range relative to the lever 30.

Further, the float 36 and the connecting rod 35 are positioned so that they do not interfere with the rotation of the packet 14.

Reference numeral 37 shown in FIGS. 2, 4, etc. is an operating lever, one end of which is rotatably mounted on the deck 28 by a shaft 38, and the end of this lever 37 near the shaft 38 has an upward handle. Fix 39.

This device has the above-mentioned configuration, and in a normal water intake state, as shown in FIG.
The top end is slightly protruding above the water surface.

Therefore, dust floating on the water surface is blocked by the screen D, and only surface water flows into the main body A from the water intake.

After a certain period of time has passed and a considerable amount of debris has accumulated on the outside of the screen B, each winding drum 29 is driven and the rope 27 is wound up, and each lifting frame E is moved to the packet 1.
4 and the claws 17, but at this time the claws 17 bite between the vertical rods 9 of the screen D and rise as shown in FIG.

Further, at this time, each operating lever 37 is kept in the retracted position as shown in FIGS. 2 and 4.

When the elevator frame E is raised as described above, the claw 17 is attached to the vertical rod 9.
Scrape out any pieces of wood that are stuck in between, and remove packet 1.
4 Drop on top.

Also, at this time, the packet 14 is moved to the roller 2 at the end of the arm 21.
2 is in contact with the guide rail 23, so the packet 14
As shown in FIG. 5, the bucket emerges from the water in an upward direction, so the dust scraped off by the claws 17 and the dust near the elevator frame E are scraped up by the packet 14.

When the packet 14 that has risen by scraping up the dust reaches above the deck 28, the roller 22 at the end of the arm 21 enters the inclined part 24 of the guide rail 23 as shown in FIG. 6, and the packet 14 is directed diagonally downward. Therefore, the garbage on the packet 14 is discharged onto the deck 28.

Next, use the handle 39 to project the tip of the operating lever 37 into the ascending and descending path of the packet 14 as shown in FIG. 6, and then rotate the drum 29 in the opposite direction to loosen the rope 27.
The elevating frame E descends together with the packet 14 and the claw 17 due to its own weight.

When the descending packet 14 hits the action lever 37 and the elevating frame E continues to descend, the packet 14 rotates upward around the descending shaft 13 and points upward, causing the pin 32 of the packet 14 to move toward the movable locking lever 37. It engages with the engagement notch 33 of.

In this state, the packet 14 moves down the action lever 37 and enters the water, and the float 36 also enters the water and generates buoyancy.The buoyancy pushes up the connecting rod 35, causing the locking lever 30 to rotate upward and the notch 33 to open. The packet 14 comes off the pin 32 and rotates forward due to its own weight, and the roller 2
2 hits the guide rail 23 and returns to the position shown in FIG.

Note that the garbage discharged onto the deck 28 as described above is appropriately collected and removed by a worker or the like.

This idea was developed as mentioned above.
At the bottom of the lifting frame E having a float 10 that moves up and down along Therefore, all of the garbage scraped by the claw 17 falls onto the packet 14 and is received by this packet 14. When the elevator frame E reaches its upper limit, the packet 14 turns downward and the garbage from the packet 14 falls onto the deck 28. Since the dust is dropped on top, the dust removal effect is extremely effective.

In addition, since the claw 17 is oriented diagonally upward toward the dust removal screen D and can freely swing between the inner and outer stoppers 26, when the claw 17 is raised, pieces of wood caught between the vertical rods 19 can be removed. When the claw 17 hits the garbage, the claw 17 digs deeper between the vertical rods 9 due to the resistance of the garbage and rises while hitting the stopper 26 of the screen D, so that it is sandwiched between the vertical rods 9. The dust removal effect is a dog.

Further, even if the claw 17 hits dirt remaining between the vertical bars 9 when the claw 17 is lowered, the claw 17 escapes until it hits the outer stopper 26, so that it does not interfere with the lowering of the elevator frame E.
