Description

[Detailed description of the invention] Industrial application field This invention allows stored water to flow in from the mouth on the circumference of the water intake plate by moving the water intake plate installed at the upper end of the water intake pipe up and down according to the water level. It is installed in a dam as a surface water intake device.

Prior art A cylinder-type surface water intake system in which an intake pipe consisting of a telescoping multi-stage cylinder is installed at the front of the water intake tower and is moved up and down according to the water level, allowing stored water to flow in from the intake plate spout at the top of the water intake pipe. The device is
For example, it is generally known from Utility Model Publication No. 58-5701, etc., but since dust adheres to the screen installed at the mouth of the water intake, the conventional method of removing it was to move a boat close to the mouth. They went around and removed them manually using rakes, etc. However, such manual work is dangerous, unstable and inefficient due to the flow velocity in the inflow section.

Purpose of the invention This invention addresses these conventional drawbacks.The purpose of this invention is to create a safe and efficient dust remover that rotates along the circumference of the screen installed at the mouth of the water intake basin. An object of the present invention is to provide a dust removal device for a water intake screen that can perform stable screen dust removal work.

Configuration Therefore, in this invention, a water intake plate is provided at the upper end of the water intake pipe consisting of a telescoping multi-stage cylinder, and a screen is provided at the mouth opening around the entire circumference to prevent the inflow of dust. In a surface water intake cylinder gate that takes in water from the mouth through a screen and discharges it downstream from the bottom of the intake pipe, a running trolley that runs along the periphery of the upper plate of the intake plate is provided, and a screen is attached to the running trolley. A dust remover for scraping up and removing dust adhering to the screen surface is provided, and a dust collecting container for collecting the dust scraped up from the screen surface is detachably attached to the dust remover.

Embodiment Figure 1 shows the case where the present invention is applied to an independent tower type surface water intake device. 1 is an intake pipe consisting of a telescopic multi-stage cylinder, and a water intake plate 2 is attached to the upper end.
is provided, and a spout 3 is opened all around the circumferential side thereof. The spout 3 is provided with a screen 5 that prevents dust from entering. Reference numeral 4 denotes a guide post erected at the center of the water intake pipe 1, and the water intake pipe 1 is guided by this guide post 4 and moves up and down.

6 is a water intake tower, which has a joint room 7 at the top.

The top plate 8 of the water intake board 2 is provided with a traveling cart 9 that runs along its periphery. A dust remover 10 for scraping up dust adhering to the surface of the screen 5 is installed on the traveling cart 9.

The traveling bogie 9 has rails 1 laid on the top plate 8.
Two front and rear wheels 12 and 12' are mounted on the carriage 1, and these wheels are driven by a driving device such as a traveling motor 13 and a chain 14 mounted on the carriage, so that the carriage 9 rotates on its own. Configure.

The dust remover 10 is a rotary type in which a bucket (or rake) 16 for scraping up dust is attached to a generally used endless link chain 15. Attach the dust remover body to beam 17.

The endless link chain 15 is hooked onto a pair of upper and lower sprockets 18 and 19, and is interlocked by a chain 21 from a dust remover drive motor 20 provided on the truck 9, so that the dust remover is fed at a constant speed. 22 is a guide roller for preventing the traveling carriage 9 from falling.

The dust collecting container 23 has a basket-like structure with side and lower parts made of net, and the lower part can be opened and closed.

This dust collection container 23 is for collecting the dust scraped up by the bucket 16 of the dust remover.A receiving metal fitting 24 is attached to the tip of the beam 17, and the hanging handle 23a of the container 23 is hung on and removed from it to freely suspend the dust. When the container is full, it is suspended from an automatically removable hook 25 attached to a winch (not shown) and pulled up to the operation room 7, or it is mounted on a separate boat or the like for disposal.

The hook 25 is attached to the tip of a lifting beam 27 that moves up and down along a guide 26, and is moved up and down using a wire rope 28 wrapped around a winch. 29 is a guide roller.

Operation When the traveling motor 13 runs the traveling cart 9 and stops it at a predetermined position, when the dust remover drive motor 20 is operated next, the dust remover is driven at that stop position, so the endless link chain is activated. A bucket 16 attached to the screen 15 is sent one after another to scrape up the screen 5 from below and remove dust. The garbage scooped up by the bucket 16 is collected in a dust collection container 23 which is placed in advance when the bucket 16 is turned over at the top. In this way, the dust remover 10 is moved together with the traveling trolley 9 to the desired position of the intake part of the water basin, and the surface of the screen 5 is scraped up at the necessary locations with a bucket to remove dust, and the scraped up dust is left as is. The dust is collected in the dust collection container 23 and the work is carried out until it is full. When the dust collection container 23 is full, the traveling trolley 9 is driven again to return to the original starting position (the position where the hook 25 is located), and the container 23 is suspended by the hook 25 and carried away to a predetermined location to be emptied. .

Effects of the device As explained above, this device is equipped with a running cart that runs along the periphery of the top plate of the water intake board.
Since the traveling trolley is equipped with a dust remover that scrapes up the dust adhering to the screen surface, the traveling trolley allows the dust remover to be moved freely to the desired position on the screen surface, making it possible to timely and reliably remove dust from the entire circumference of the screen. It is safer and more efficient than the dangerous dust removal work done by
It is possible to maintain and manage surface water intake performance.
