Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple dust remover which has a simple structure for setting a relatively small-scale intake port and a water conduit and has reduced manufacturing and maintenance costs.

[0002]

2. Description of the Related Art A grid-like screen provided for catching dust particles in running water at a water conduit, an intake port, etc. has conventionally been provided with a rake that raises the rake along the front surface of the screen to collect dust particles. It is equipped with a full-fledged dust remover that can scoop up.

[0003]

However, the conventional dust remover is provided with a rake having the full width of the screen so that it can be moved up and down by, for example, a rotary chain or a reciprocal wire rope. Therefore, there is a problem that the manufacturing and maintenance costs must be high.

Therefore, such a large-sized dust remover is not provided at an intake or the like where the amount of collected dust is usually small, and a rake is used to manually remove dust, but
Since manual work is also a hard work without danger, even a worker who is physically strong has reached the fatigue limit in 20 to 30 minutes and is not able to obtain a sufficient dust removal result. Therefore, a simple dust remover that can be provided at low cost has been desired.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is to provide a simple dust remover which can meet the above-mentioned demands, in which a suspension rail is horizontally supported above a screen provided in a water channel, and the suspension rail is suspended. A suspension frame is hung so that it can be moved along the rails, and a drive unit such as a handwheel is provided on the suspension frame, and a chain guide is hung from the suspension frame along the front surface of the screen so that the drive unit is driven. A chain wheel connected to the chain guide is provided at the upper end of the chain guide, and an endless chain is wound between the chain wheel and the chain wheel rotatably provided at the lower end of the chain guide. Fix the rake that slides on the front,
The rake can be slidably contacted over the entire width of the screen by transversely moving the suspension frame along the suspension rail.

[0006]

Since the rake can be moved in the width direction of the screen by moving the suspension frame, even a small rake can be slid on the entire width of the screen to scoop up dust. Therefore, the entire device can be downsized and the structure can be simplified.

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of this simple dust remover, and FIG. 2 shows a vertical sectional view thereof. In the figure, 1 is a screen in which a large number of crosspieces are provided in parallel at a fixed interval in order to capture dust in a water channel 2 in which water flows in the direction of the arrow, and 3 are columns 3a and 3a on both sides of the water channel 2. The suspension rails 4 made of I-shaped steel that are horizontally supported above the screen 1 and are horizontally suspended above the screen 1 so as to be movable along the suspension rails 3. The suspension frame 4 is assembled into a front concave shape with a steel material, and sliding portions 6 and 6 are connected to both upper end portions of the suspension frames 6 and 6 so as to be bendable, and the suspension rails 3 are attached to the respective sliding portions 6 and 6. Trolley rollers 7 and 7 are provided so that they can roll on the top with light friction.

Reference numeral 13 is a drive portion provided on the suspension frame 4,
A bracket 8 is provided on one side of the suspension frame 4
The handle shaft 10 is supported by the bearings 9, 9 provided above, and the chain wheel 11 is fixed to the handle shaft 10 and a large-diameter wheel-shaped handwheel 12 is fixed to one end of the handle shaft 10. .

Reference numeral 14 is a prismatic chain guide fixed to the center of the lower edge of the suspension frame 4, and the chain guide 14 is supported by the suspension frame 4 and hangs down along the front surface of the screen 1. A bearing 16 is provided on the upper end of the chain guide 14, a chain wheel 18 is fixedly mounted on a transmission shaft 17 rotatably supported by the bearing 16, and the transmission shaft 17 is also supported by a bearing 19 on a part of the suspension frame 4. Then, a chain wheel 20 is fixed to the other end of the transmission shaft 17, an endless transmission chain 21 is wound around the chain wheel 20 and the chain wheel 11, and the handwheel 12 is rotated to rotate the chain wheel 11. , Transmission chain 21, chain wheel 2
0, the chain wheel 18 is connected via the transmission shaft 17 so as to be rotationally driven.

A bearing 22 is provided at the lower end of the chain guide 14 to rotatably support the chain wheel 23, and an endless chain 24 is wound between the chain wheel 23 and the chain wheel 18 to form an endless chain. Rake 25 is attached to a part of 24 at regular intervals. The rake 25 is shown in FIG.
As shown in FIG. 4, a rectangular plate-like member connected to the endless chain 24 with a mounting metal fitting 26 is provided with comb teeth 27, 2 projecting between the crosspieces of the screen 1 at the contact side with the screen 1.
A sliding contact member 29 having 7 ... Is fixed by bolts 28, 28.

Reference numeral 30 denotes an apron fixedly provided on the upper end of the screen 1, and 31 denotes a dust discharging slab formed on the rear side of the apron 30.

Reference numeral 32 denotes a transverse support rod horizontally fixed to the back surface of the chain guide, and transverse support rollers 33 capable of rolling on the surface of the apron 30 at both ends of the transverse support rod.
33, the apron 30 and the traverse support rollers 33, 33 support the chain guide 14 and the suspension frame 4 in a slanting suspension as shown in FIG.

In the simple dust remover constructed as described above, the hand-turning handle 12 is rotated to circulate the endless chain 24 as shown by the arrow, and the rake 25 is slidably contacted along the front surface of the screen 1. The dust adhering to the screen 1 can be hooked on the scraping teeth 27, 27 ... and scooped up, and the dust can be removed on the slab 31 to remove dust with a light work. Then, shift the rake 25 so that it does not match the front surface of the screen 1,
By horizontally moving the suspension frame 4 along the suspension rail 3, the rake 25 can be horizontally moved horizontally. Therefore, even if the width of the rake 25 is less than the width of the screen 1, the horizontal movement is possible. If the scooping operation is performed as described above, dust can be sufficiently removed even with a wide screen with a small rake.

In this embodiment, the manual handle 12 is provided as the driving unit provided on the suspension frame 4, but a small motor is used as a power source at a place where power can be obtained instead of such a handle. It is better to provide it.

[0015]

As described above, in the simple dust remover of the present invention, the chain guide is movably suspended along the suspension rail via the suspension frame so that the rake can be slid over the entire width of the screen. . Therefore, it suffices to provide a small rake to support the rake,
There is a beneficial effect that the manufacturing and maintenance costs can be greatly reduced without requiring much strength such as a chain guide.
