DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater waste collection apparatus for collecting and collecting waste floating in water.

[0002]

2. Description of the Related Art Generally, stationary dust removal equipment is installed at water intakes and drains of lakes, marshes, dam reservoirs and the like. In addition, in the closed water area, there is a stagnant water area in which garbage is stored in addition to the intake port and the like, and a dust removing boat is employed as a dust removing facility for the stagnant water area. This is because the moving direction of the refuse varies depending on the wind direction and the refuse stays in a relatively wide area. Is the current situation (62-18, Shokai)
No. 7998) .

[0003] The catamaran hull flows into a well for running water.
Floating material is rotated by a rotating plate (water turbine) that rotates in a semi-submerged state.
And drop it into the suspended cargo hold on the hull.
A proposed suspended matter recovery apparatus has been proposed (Japanese Patent Application Laid-Open No. 54-1979).
-90781).

[0004]

By the way, in the conventional stationary dust removal equipment, the operator does not need to cling to the equipment and can operate automatically. There is a problem that must be collected by. In addition, in the dust removing ship, there is a problem in that workers cannot leave the ship and labor is saved, and efficiency is poor.

Further, Japanese Patent Application Laid-Open No. 54-90781 discloses
In the disclosed suspended matter recovery device, the suspended matter
Although rubbish can be collected, algae growing naturally in lakes and marshes
There is a problem that it cannot be removed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to efficiently collect stagnant refuse in closed water areas such as lakes and marshes and reservoirs, and at the same time to collect refuse and aeration. the performed, increasing the amount of oxygen dissolved in water, addition can be performed to improve water quality, water
It is an object of the present invention to provide an underwater waste collection device capable of cutting and removing algae therein .

[0007]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention relates to two floating bodies connected in parallel with each other at an interval.
In between, the garbage collection conveyor is located at the bottom,
A water wheel is arranged above the conveyor and positioned at the front end of the floating body.
Garbage that rotates around a vertical axis and opens and closes horizontally
Attach one end of the class guide body, and
Can be put into a collection container or a conveyor
In the underwater waste collection device, the inner surface facing the floating body
The bottom plate is located between the lower ends of the belly plates
It is fixed, inclined to provided et front end of the bottom plate forwardly downward
And the waste collection conveyor along the upper side of the bottom plate
Rake is provided on the refuse collection conveyor
Is provided.

The present invention is also directed to a rear end of the left and right abdominal plates of each floating body.
A rear screen is arranged in an extended manner and parallel to the rear screen.
Waste collection container or scraping below the screen
It is characterized in that a conveyor is provided.

[0009]

According to the present invention, while the entire apparatus is floating underwater, it is moored in a stagnant water area where garbage collects most in the direction of the wind to rotate the water wheel, and also to collect garbage on a conveyer, scraper. When the lifting conveyor starts operation, garbage is conveyed between floating bodies by the garbage collection conveyor,
A flow is generated in the retained water, dust is rushed by the water turbine to generate a flow, and aeration is performed by entraining the atmosphere into the water and scooping up the water by the water turbine.

Therefore, the refuse floating in the stagnant water area gathers toward the refuse guide body due to the flow of water, and is affected by the wind when there is a wind, and the refuse is automatically collected. Collective collection can be performed and landed by container or conveyor. Further, the amount of dissolved oxygen in the pond water increases due to the aeration effect of the water turbine, the water quality is improved, and the activation of lakes and marshes can be promoted.

Further, the mooring of the device is released, and the watercraft is used as a propulsion device, so that the watercraft can function as a collecting vessel and a large amount of waste can be collected. And on the inclined front end of the abdominal plate
A waste collection conveyor is provided along with a cutter.
Because it has a rake, underwater algae can be
Can be reaped and collected
The rear part following the inclined part of the conveyor is substantially horizontal.
Waste is collected smoothly by running water
Or, it is put into a scraping conveyor.

According to the present invention, the rear ends of both floating bodies are provided at the rear end.
Because it is equipped with a clean, the water flow from the turbine
Separates left and right from the rear edge and passes smoothly through the rear screen
Waste that has flowed into the
It is collected by the lean and collected reliably.

(2) A stage (32) is provided on the upper side so that a driver can ride on the stage. Then, the container (3)
1) is constituted by a net or the like so as to drain the water.

An anchoring wire (34) has one end fixed to the floating bodies (1) and (2) (or the support frame (32)). When a load equal to or more than a predetermined load is applied to the lower portion of the water turbine (11), the recovery conveyor (9) bends downward (belt) as shown by a two-dot chain line (9A) in FIG. The waste is prevented from clogging between the conveyor (9) and the water wheel (11) so that the waste can be smoothly carried in. The bending of the conveyor (9) is performed similarly in the first embodiment. The present invention is not limited to the above embodiments, and the design can be changed as appropriate. For example, the drive of the water wheel (11), the drive of the conveyor (9), and the like can be performed by solar power generation.
