Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a dust removal device for waterways, particularly in remote areas without electricity, such as mountainous areas.

(Prior Art) Conventionally, this type of dust removal equipment has been operated by a worker at the machine side at any time due to the engine drive.
Alternatively, commercial power was used to supply sufficient power for operation.

(Problems to be solved by the invention) When the conventional dust removal equipment is installed in a waterway in a remote area without electricity, such as a mountainous area, it must be driven by an engine or require the installation of a commercial power source. be.

However, when the dust removal equipment is driven by an engine, it is difficult to automatically operate it by detecting the water level difference when the screen is clogged, or to automatically operate it according to the timer setting, and a worker must come and operate the equipment at the machine. Must be. In addition, bringing in commercial power to areas without electricity requires a huge amount of cost, and from the standpoint of investment efficiency, bringing in commercial power is avoided.

(Means for solving the problem) The present invention was proposed in order to solve the above problem. A rake opening/closing mechanism configured to open and close the rake, an electric motor for lifting and lowering the rake, a driving power source for the electric motor which is a combination of a solar cell and a storage battery, and upstream and downstream sides of the screen disposed in the waterway. The rake opening/closing mechanism includes a water level gauge that detects a water level difference between the two sides and issues an activation signal to the electric motor, and the rake opening/closing mechanism has upper and lower flaps pivotably supported in cutouts provided above and below the lifting guide rail so as to be freely openable and closable. At the same time, a guide plate is attached to the upper flap, and when the rake is lowered, the lower flap on the guide rail of the rake is pushed and opened by the guide roller of the rake, and the roller is pushed to the outside of the guide rail. The dust removal device is characterized in that the guide roller is guided into the guide rail by the upper flap and the guide plate and returns into the rail when the rake rises. This is related.

(Function) Since the present invention is constructed as described above,
Clogging of the screen is detected by detecting the water level difference between the upstream and downstream sides of the screen disposed in the waterway using the water level section, and the detection signal is sent to the electric motor for lifting and lowering the rake. The electric motor raises the rake type rake along the elevating guide rail, scrapes up the dust on the screen, and during the ascent process, it is opened by the rake opening/closing mechanism disposed in the elevating guide path, and the rake is raised along the elevating guide rail. The dust thus stirred up is discharged to the required location.

Furthermore, the rake is closed and closed by the opening/closing mechanism during its descent process, and occupies a position where it can scrape up dust on the screen.

The electric power for driving the electric motor for raising and lowering the rake is supplied from a power source that is a combination of a solar cell and a storage battery.

Further, when the rake is lowered, the lower flap, which is pivotally supported at the lower part of the guide rail of the rake so as to be openable and closable, is pushed by the guide roller and opened, and the guide roller comes out of the guide rail, and the rake is moved to the upper limit position. When the guide roller rises to the vicinity, it is guided by the upper flap and the guide plate and returns to the inside of the guide rail.In this way, the rake is opened and closed by an opening/closing mechanism consisting of the upper and lower flaps and the guide plate provided on the guide rail. Since the rake is opened and closed as the rake moves up and down, power for opening and closing the rake can be omitted and power consumption can be minimized.

(Effects of the invention) As described above, according to the invention, the rake of the dust removal device is opened and closed by the rake opening/closing mechanism provided on the lifting guide rail as the rake of the dust removal device moves up and down, so the opening and closing power of the rake is omitted. The power for lifting and lowering the rake can be suppressed to the necessary minimum, and the electric motor for lifting and lowering the rake can be easily driven by a drive power source that is a combination of a solar cell and a storage battery.

Furthermore, the raising and lowering operation of the rake is automatically performed by a water level gauge that detects the water level difference between the upstream side and the downstream side of the screen, detects clogging of the screen, and sends an activation signal to the lifting motor. It is.

As described above, according to the present invention, it is possible to install a dust remover that operates automatically even in a remote mountainous area without electricity, making it possible to efficiently use waterways and reduce the cost required for dust removal.

(Example) The present invention will be described above with reference to the illustrated embodiments.

Reference numeral 1 denotes a rake-type rake made of a lightweight alloy such as aluminum alloy, 2 a screen disposed on the waterway, and 3 guide rails with an H-shaped cross section disposed on both sides of the rake on the waterway surface.

On both the left and right sides of the rake 1, there are main rollers 4 that roll on the lower flange of the guide rail 3 with an H-shaped cross section.
A guide roller 5 is disposed above the roller 4 and rolls on the upper flange of the guide rail 3, and a screen 2 is attached to the lower end of the rake 1 when the rake 1 is raised.
A front roller 6 is mounted on the screen 2 to keep the rake 1 stable and reduce the frictional resistance between the rake 1 and the screen 2.

At the lower part of the guide rail 3, the upper end of a lower flap 7 is rotatably supported 8 on the upper edge of a cutout provided in a part of the upper flange, and is configured to open and close the cutout. There is. (See Fig. 5) In addition, at the upper part of the guide rail 3, the lower end of the upper flap 9 is pivoted 10 in a notch provided in a part of the upper flange, and a weight 11 is attached to an extension of the pivot part of the flap 9. is attached, and the upper flap 9 is always urged to rotate in the direction of the half-hour hand by the weight of the weight 11, and is configured to close the notch in the upper flange of the guide rail 3. There is. Furthermore, a guide plate 12 is provided on the guide rail 3 to cover the notch.
is installed protrudingly.

A stopper rubber 14 for suppressing rotation of the rake 1 at the upper limit position of the rake 1 and a scraper rubber 15 for scraping off the dirt scraped up by the rake 1 are disposed on the pedestal 13 that supports the guide rail 3.

Further, an electric motor 16 for raising and lowering the rake is mounted on the frame 13, and a wire 18 wound around a winding wheel 17 attached to the drive shaft of the electric motor 16 is connected to the guide rail 3.
The wire 18 is suspended over a pulley 19 at the top of the
The tip of is connected to rake 1.

In the figure, 20 is a dust collection gutter.

A water level gauge 21 for detecting the difference in water level between the upstream side and the downstream side of the screen 2 is mounted on the pedestal 13,
When the water level difference between the upstream side and the downstream side exceeds a certain limit due to clogging of the screen 2, this water level difference is detected, and a detection signal is sent to the electric motor 16 to operate it. .

In the figure, 22 and 23 are water pipes for detecting water levels on the upstream side and the downstream side, respectively.

Reference numerals 24 and 25 are solar cells and storage batteries that constitute the driving power source for the electric motor 16, and 26 is an operation panel.

Since the illustrated embodiment is configured as described above, when the screen 2 becomes clogged, the water level gauge 21 detects a water level difference of more than a certain limit between the upstream side and the downstream side of the screen 2. , this detection signal is sent to the electric motor 16, and the same electric motor 16 outputs the rake 1.
When the rake 1 is lowered, both the main roller 4 and the guide roller 5 move toward the guide rail 3 with an H-shaped cross section.
The rake 1 rolls along the lower flange and the upper flange of the guide rail 3, respectively.
As shown by the two-dot chain line in the figure, it is in an open state, and the front roller 6 is in a free state.

Since the upper flap 9 cannot be opened from the inside of the H-shaped cross-section guide rail 3, the guide roller 5 is
It passes through the inside of the same guide rail 3 as it is. When the guide roller 5 approaches the lower flap 7,
The lower flap 7 is pushed by the guide roller 5 and opens outward from the inside of the lower part. When the lower flap 7 opens to a certain angle, it stops against a stopper (not shown), and the guide roller 5 moves along the angle to the outside of the guide rail 3. Go out.

As a result of this operation, the rake 1 descends in an open state, and at the lower limit position rotates counterclockwise in the direction of the hour hand as shown by the solid line in FIG. 1 to be in a closed state.

When the rake 1 is closed, the front roller 6 rides on the screen 2 and the main roller 4
is inside the guide rail 3, and the guide roller 5 passes the lower flap 7 and becomes free. Further, when the guide roller 5 passes, the lower flap 7 returns to its original position due to its own weight, and the rake 1 rises.

When the rake 1 is rising, the main roller 4 is inside the guide rail 3 and contacts the lower flange, the front roller 6 contacts the screen 2, and the guide roller 5 is in a free state.
When the front roller 6 comes off the upper end of the screen 2, the rake 1 swings downstream about the main roller 4. At this time, rake 1 is stopper rubber 1.
4, the swing to the downstream side stops. Due to this impact, most of the dust raked up by the rake 1 falls into the dust collection gutter 20. When the rake 1 further rises, the guide roller 5 enters the guide plate 12 and moves along the guide plate 12.

The guide roller 5 pushes the upper flap 9 and enters the guide rail 3. When the guide roller 5 passes, the upper flap 9 returns to its original position. This action causes
The rake 1 changes from the closed state to the open state.

Also, at this time, the scraper rubber 15 is
The dust remaining on the upper surface of the rake 1 is brushed off, the raked up dust is completely contained in the dust collection gutter 20, and the rake 1 reaches its upper limit position.

In this way, the opening/closing mechanism of the rake 1 is operated by the upper and lower flaps 9, 7 provided on the guide rail 3, and the guide plate 12.
Since the rake 1 is opened and closed along with the lifting and lowering movement by an opening and closing mechanism, the power mechanism for opening and closing the rake 1 can be omitted and operation can be performed only by the electric motor 16, and power consumption can be minimized. .

This provides an energy-saving dust removal device that can be operated using electric power using a power supply device that combines the solar cell 24 and the storage battery 25.

In the dust remover powered by the solar cell 24 of the present invention, as described above, the electric motor 16 for raising and lowering the dust remover is a small DC motor with low power consumption, since a small capacity motor 16 can sufficiently drive the dust remover. can be used. Further, the electric motor 16 can be operated by storing electric power generated by a solar cell 24 in a storage battery 25.

As described above, according to the present invention, the power for opening and closing the rake 1 is omitted, and the hoisting power is kept to the necessary minimum, thereby making it possible to easily operate the dust remover using a power supply device that combines the solar cell 24 and the storage battery 25. equipment can be installed.

This makes it possible to install dust removers that can operate automatically even in remote mountainous areas without electricity, making efficient use of waterways and reducing the cost required for dust removal.

Although the dust remover can be operated by pressing a button on the machine when adjusting the equipment, it is usually operated unmanned. When a certain water level difference is detected by a water level gauge 21 which detects the clogging of the screen 2 by the water level difference between upstream and downstream sides of the screen 2, the dust remover automatically performs one scraping operation and then automatically stops. Further, a timer may be used that can be set to perform automatic operation at fixed time intervals so that the raking operation can be performed twice a day up to 5 times a day.
