Floating garbage collection system {SYSTEM FOR COLLECTING FLOATING GARBAGE}

The present invention relates to a floating waste collection system.

In general, floating garbage floating on the sea surface adversely affects not only the marine ecosystem, but also adversely affects human life, such as causing ship accidents.

Floating garbage floating on the sea surface increases the moisture content as time goes by, and due to an increase in its own weight due to the attachment of various microorganisms or shellfish, it gradually sinks into the water.

The inner container 12 may be disposed in at least a portion of this space, and the inner container 12 may be disposed to be spaced apart from the outer container 11 inside the outer container 11 . For example, the outer container 11 may be made of a material capable of floating on the sea level, and may have a hollow cylindrical shape. A side shaking reducing member 112 for reducing side shaking may be connected to the outer surface of the outer container 11 .

The upper plate 13 may be coupled to the open upper portion of the outer container 11 . The upper plate 13 may connect between the inner surface of the outer container 11 and the outer surface of the inner container 12 at the open top of the outer container 11 . For example, the upper plate 13 may be provided as a ring-shaped plate member. The upper plate 13 may prevent seawater or floating garbage from flowing between the outer container 11 and the inner container 12 from the upper part of the outer container 11 .

The lower plate 14 may be detachably coupled to the open lower portion of the outer container 11 . In this case, as the lower plate 14 is made of, for example, a material having a predetermined weight, the outer container 11 may be submerged in water to a predetermined depth.

A plurality of passage holes 141 through which seawater may pass may be provided in the lower plate 14 . The passage hole 141 may be formed, for example, in a size that allows seawater to pass through, but does not allow floating garbage to pass therethrough. The seawater introduced between the outer container 11 and the inner container 12 is moved to the lower side of the outer container 11 by the compressed air flowing between the outer container 11 and the inner container 12 and then passes through a plurality of through holes. It can be discharged into the water through (141). This will be discussed later.

An upper portion of the inner container 12 disposed inside the outer container 11 may be disposed substantially on the same line as the upper portion of the outer container 11 . The inner surface of the outer container 11 and the outer surface of the inner container 12 may be spaced apart from each other by a predetermined distance. A space between the inner surface of the outer container 11 and the outer surface of the inner container 12 may be used as a space capable of adjusting the buoyancy of the waste collection unit 10 .

To this end, the sieve member 15 may have an open top, and may have a space in which floating garbage can be accommodated. For example, the sieve member 15 may be provided as a mesh member capable of passing a liquid such as seawater and filtering solids such as floating garbage. In order to facilitate the detachment operation of the sieve member 15 with respect to the inner container 12, a holding part (not shown) that can be gripped by an operator may be connected to the upper portion of the sieve member 15 .

The signal for the flow of algae detected by the sensing unit 20 may be used to adjust the buoyancy of the garbage collection unit 10 . This will be discussed later.

The buoyancy control unit 30 may selectively levitate the garbage collection unit 10 from the sea level by adjusting the buoyancy of the garbage collection unit 10 based on the flow of the current detected by the sensing unit 20 . For example, the buoyancy control unit 30 increases the buoyancy of the garbage collection unit 10 when the flow of the current detected by the detection unit 20 is low tide so that the garbage collection unit 10 floats from the sea level. .

To this end, the buoyancy control unit 30 includes a housing 31 disposed on the upper portion of the garbage collection unit 10, an air compressor disposed inside the housing 31, and sucking and compressing outside air to generate compressed air ( 32) and one end connected to the air compressor 32, the other end disposed between the inner surface of the outer container 11 and the outer surface of the inner container 12, the compressed air generated by the air compressor 32 It may include a compressed air transfer line 33 for transferring between the inner surface of the outer container 11 and the outer surface of the inner container (12). At this time, between one end and the other end of the compressed air transfer line 33 may be supported by the first support member 37 coupled to the upper plate (13).

The air compressor 32 may receive external air through an air vent (not shown) connected to the housing 31 . The air vent is provided with a shut-off valve (not shown), and the shut-off valve is closed when the garbage collection unit 10 is submerged in water to a predetermined depth, and can be controlled to open when the garbage collection unit 10 rises from the sea level. have. The air compressor 32 may be electrically connected to the power supply unit 40 to selectively receive power from the power supply unit 40 .

Between one end and the other end of the seawater discharge line 36 may be supported by the second support member 38 coupled to the upper plate (13).

The seawater pump 34 may be electrically connected to the power supply unit 40 to selectively receive power from the power supply unit 40 . The seawater sucked from the inner container 12 by the driving of the seawater pump 34 may be purified through the filter member 39 and then discharged through the seawater discharge line 36 . In this case, the filter member 39 may be provided as a filter capable of filtering microplastics contained in seawater.

The power supply unit 40 may provide power required for driving the air compressor 32 and the seawater pump 34 to the air compressor 32 and the seawater pump 34 . To this end, the power supply unit 40 may be disposed inside the housing 31 . In addition, the power supply unit 40 may be provided, for example, as a battery power generation module in order to stably supply power to the air compressor 32 and the seawater pump 34 irrespective of the marine environment situation.

The controller 50 may control the buoyancy control unit 30 by comparing and analyzing the data on the flow of the current sensed by the sensor 20 and the data on the flow of the pre-stored current.

To this end, the controller 50 may include, for example, a small built-in computer, and may include a data processing unit including a program, a memory, and a CPU. Here, the program may include an algorithm for controlling at least one of the air compressor 32 and the seawater pump 34 based on the tidal flow signal transmitted from the sensing unit 20 . In addition, such a program may be stored in a memory such as a computer storage medium, for example, a flexible disk, a compact disk, a hard disk, an MO (magneto-optical disk), and installed in the control unit 50 .

Hereinafter, the operation and effect of the floating garbage collection system according to an embodiment of the present invention will be described with reference to FIG. 7 .

Referring to FIG. 7 , since it is necessary to collect the floating garbage at high tide when floating garbage floating on the sea level can float to the land, if it is determined by the sensing unit 20 that the flow of the current is high water, the operator The garbage collection unit 10 is installed so that the collection unit 10 is submerged in water.

The garbage collection unit 10 installed in this way may be floated on the sea in a state submerged in water to a predetermined depth by its own weight. When the garbage collection unit 10 is submerged in water to a predetermined depth, floating garbage floating on the sea level flows into the inner container 12 together with seawater.

Next, when the flow of the current becomes weaker than the initial one by the detection unit 20 or changes from the high tide to the low tide, a signal for the flow of the tide detected by the detection unit 20 is transmitted to the control unit 50 in real time. The control unit 50 compares and analyzes the algae flow signal received from the sensing unit 20 and pre-stored algae flow data.

If it is determined that the flow of the current detected by the sensing unit 20 is low tide, there is no concern that the floating garbage floating on the sea level will float to the land, so there is no need for the garbage collection unit 10 to collect the floating garbage. Accordingly, the controller 50 controls the air compressor 32 to be driven so that the compressed air of the air compressor 32 flows into the outer container 11 and the inner container 12, and drives the seawater pump 34 to The seawater introduced into the inner container 12 is discharged to the outside of the inner container 12 .

The seawater previously introduced into the inner container 12 is discharged to the outside, and the compressed air introduced between the outer container 11 and the inner container 12 is seawater pre-introduced between the outer container 11 and the inner container 12 . is pushed into the water, the buoyancy of the garbage collection unit 10 increases, so that the garbage collection unit 10 rises from the sea level. Since floating garbage is not collected in a state in which the garbage collection unit 10 is floating from the sea level, the air compressor 32 and the seawater pump 34 are both stopped.

Therefore, the floating garbage collection system 1 operates only at high tide when floating garbage floating on the sea level floats to the land to collect the floating garbage, and at low tide, the operation is stopped while floating from the sea level. This has the effect of preventing unnecessary power being wasted.

In addition, the floating garbage collection system 1 collects the floating garbage floating at the sea level by detecting the current flow before the floating garbage floating at the sea level is floated to the land. It has the effect of being able to prevent the harmful effects caused by it in advance.

In addition, since the operation of the floating garbage collection system 1 is supplied with power by the self-battery power module mounted therein, it is not affected by external environmental changes, and the floating garbage collection efficiency is achieved through efficient and stable power supply. This has the effect of improving it.
