Description

River Floating Material Collection System {River Floating Material Collection System}

The present invention relates to a river floating matter collection system, and more particularly, to a river floating matter collection system having an improved structure so as to collect floating matter introduced from a small river without using power.

Recently, more than 150,000 tons of marine garbage is generated nationwide, and the amount generated is more than the amount collected. What is more serious is that the pollution of the marine environment is accelerating day by day due to the increasing amount of garbage, while spawning and habitat destruction of marine organisms are also becoming serious. The need for prompt action is being emphasized.

On the other hand, waste plastic is the most common among coastal litter. According to recent statistics, plastic waste accounts for about 60% of all coastal litter. followed by wood and glass. In terms of types of plastic waste on the beach, beverage bottles or lids (26.2%) were the most common, followed by Styrofoam buoys (20.7%), fishing ropes (17.1%), and plastic bags (11.8%). Of the total coastal garbage, the proportion of garbage imported from abroad is 4.1%, of which garbage imported from China accounts for 95%.

The government plans to expand and install barriers to prevent land waste from flowing into the sea from rivers. We also decided to come up with a plan to recycle the collected plastic waste. The biggest problem is that household waste such as plastic is not easy to recycle because it is mixed with salt from seawater and impurities (marine organisms, etc.). Alternatives are needed, such as building a marine debris pre-treatment facility to remove salt and foreign substances from marine debris. About 60% of marine waste flows through rivers, and it takes a huge amount of money to build recycling facilities for marine waste, so spill prevention and collection technologies are required to prevent marine waste from entering the ocean.

Until recently, marine waste collection activities have been promoted in the form of supporting corporations or organizations in local governments. However, the reality is that marine debris is generated more than the amount collected, and what is more serious is that marine environmental pollution is accelerating day by day due to the increasing amount of garbage, while spawning and habitat destruction of marine organisms are becoming serious, emphasizing the need for prompt countermeasures. am.

In addition to the method and technology for collecting marine debris in coastal waters, river trash leakage prevention technology and facilities are required. In the case of rivers, management entities such as national, local, and small streams are dispersed, and it is difficult to introduce facilities where the river width is wide and the water depth is deep, such as national and local rivers. Therefore, it is desirable to apply technology and facilities to prevent leakage mainly in small rivers.

In addition, it is essential to make preventive efforts to prevent garbage generated on land from entering the sea in advance, such as concentrated collection of river and estuary garbage or installation of barriers.

Conventionally, various methods for blocking or collecting such garbage on land and at sea have been proposed. Patent Registration No. 10-0468438 has a disadvantage in that the structure is complicated and construction and installation are difficult, such as installing a number of heavy steel structures in a river and attaching a fence plate to the front thereof.

A collection device with a mesh structure is installed at sea, but it is lost or damaged, so there is a limit to the collection device. Korean Registered Patent Publication No. 10-2000527 “Sea Floating Garbage Blocking Device”, which is being developed as a national project, is expected to play a role in the sea, but has limitations in its application to blocking and collecting small rivers.

In order to prevent floating debris from flowing into the sea through rivers, it is most desirable to block and collect from small tributary streams in terms of operation and effectiveness, and it is necessary to develop new types of equipment that are easy to block and collect during initial rainfall.

Hereinafter, for convenience of explanation, referring to FIG. 1, the side into which river water, which is the water of a small stream or a tributary, flows in is called an upstream, and the side passing through the floating matter collection system 100 of the present invention from the upstream to a larger river or main stream is called a downstream. .

In addition, in the present invention, the term "float" refers to objects that can float on top of river water, including plastic waste, bottles, styrofoam, wood, etc., which account for the majority of the marine debris described above.

Depending on the width of the river water, only one floating support rod 177 may be installed (not shown) or a pair may be installed, but for convenience of explanation, as shown in FIG. It is assumed that the collection device 150 is located adjacent to the bank of the river, which is both sides of the flotation device 170, while maintaining the inclination angle (see 'A' in FIG. 1) toward the upstream side.

The floating matter collection system 100 according to the present invention includes a frame 130 supported on a bank downstream of a small river flowing into a large river or a small river; A flotation device 170 including a float guide 173 coupled to the frame 130 so as to be able to float according to the water level of the river across the flow of the river water and guiding the floating object floating on the upper side of the river water to a set position, and ; It is preferable to include; a collection device 150 for collecting and accommodating the floating matter guided by the flotation device 170. In addition, the float guide 173 of the flotation device 170 is preferably disposed at an inclined angle (see 'A' in FIG. 1) inclined in the range of 15 to 30 degrees with respect to the horizontal direction of the river water flow direction. .

The frame 130 is a structure installed along an embankment such as a tributary of a small river or a somewhat large river, and includes a collection frame 135 supporting the collection device 150 and a collection frame 135 extending from the collection frame 135 to support the floating device 170. It is preferably made of a floating frame (133).

The collection frame 135 includes a steel structure or a concrete structure capable of attaching and detaching the net-shaped collection network 155 that collects and accommodates the collected floating matter and passes through the river water. It is preferable that a collection net opening 153 is formed through the collection frame 135 at the bottom of the river so that the floating matter collected by the collection device 150 can be guided to the collection net 155 .

The upper side of the collection frame 135 is somewhat narrower and the lower side is wide, and the upper side is open, and the width of the upper side (see 'W1' in FIG. 1) is narrower than the width of the lower side (see 'W2' in FIG. 1). With this structure, even if the floating matter collected on the upper side of the collection frame 135 due to the rise in the water level during the initial rain does not guide the floating matter toward the collection device 150 in the state shown in FIG. 5, the collection frame ( 135), it is possible to maintain a state in which the floating matter collected in the 'c'-shaped upper space is stably collected (see 'floating matter' on the left and right sides of FIG. 5). The floating matter collected in the collection frame 135 may descend along the water level and flow into the collection net 155 through the collection net opening 153 when the water level is lowered.

It is preferable that the collection net 155 is detachably coupled to the collection net opening 153 by a well-known attachment/detachment means of various shapes including an 'L' shape (not shown) coupled around the collection net opening 153.

When a large amount of floating matter is collected in the collection net 155, the collection net 155 is separated from the collection net opening 153 using a crane installed in a small vehicle, and the floating matter collected in the collection net 155 is recovered and collected. The net 155 may be recycled, or the collection net 155 and the floating matter may be simultaneously recovered, and a new collection net 155 having collected the floating matter may be placed in the opening 153 of the collection net. In this way, recycling is possible while maintaining durability of the collection network 155 .

The floating frame 133 is a structure that is coupled to the collecting frame 135 at a location further away from the bank of the river than the collecting frame 135 to support the floating device 170, and may be a steel material, a synthetic resin material, or a concrete structure.

A floating bearing 175 including a plastic bearing is coupled to the floating frame 133 so that the frame axis 177d of the floating support rod 177 that moves up and down according to the water level of the river can move up and down.

The flotation device 170 has a floating body 171 that is immersed in the river water and provides buoyancy to the rest of the flotation device 170, the lower part is coupled with the floating body 171, and the upper part is exposed above the river water level to the upper side of the river water The floating object guide guide 173 for guiding the floating object floating in the air to the collecting device 150 side, and the float 171 and the floating object guide guide 173 so that the float 171 can maintain the inclination angle as shown in FIG. It is preferable to include a floating support rod 177 for maintaining an inclined position in the transverse direction of river water flow.

The floating body 171 is submerged in water or partially exposed to the water as needed to provide buoyancy to the flotation device 170, and known materials such as styrofoam, a polystyrene resin foaming agent, and synthetic resin capable of providing buoyancy It is preferable to include the material of

The floating body 171 is provided with a sealing coupling hole 171b to which the floating support bar 177 can be coupled and a guide coupling hole 171a to which the floating object guide guide 173 can be coupled.

These floating bodies 171 are manufactured to a length set so that they can be arranged in parallel along the longitudinal direction of the floating support rods 177 appropriate for the width of the river water, and are coupled to the floating support rods 177 by the required number according to the width of the river water It is easy to use and very convenient to install and maintain.

The floating guide guide 173 has a lower side coupled to the floating body 171 and an upper side having a plate shape that can be exposed higher than the river water level, and is coupled to the floating body 171 in the horizontal direction of the river water flow direction and the river water level. It is exposed to the river water while maintaining the inclination angle.

In this way, the floating matter flowing along the upper side of the river water can be guided toward the collecting device 150 by the floating material guide guide 173 exposed to the upper side of the river water while maintaining the inclination angle set to the upper side of the river water.

The floating support bar 177 is preferably provided in a round or rectangular long rod shape. At the side of the floating frame 133, which is one end of the floating support rod 177, the frame shaft 177d is coupled with the floating bearing 175 so as to be movable up and down according to the water level of the river, and at the center side of the other end, the river water, each floating support rod ( 177) is provided with mutually engaging end engagement portions 177a so that the floating body 171 can move up and down according to the water level while maintaining the inclination angle, so that the floating support rods 177 can maintain a state of being engaged with each other.

The floating support bar 177 preferably includes a rod-shaped body (not shown), a frame shaft 177d, and an end engaging portion 177a, as well as an elastic deformation portion 177b and a bending guide portion 177c.

As shown in FIG. 4A , the end engagement portion 177a may include an end engagement portion 177a-1 and an end engagement portion 177a-2 to maintain a mutually engaged state. The structure of the end engagement portion 177a may be provided by other known means.

The elastic deformation part 177b or the bending induction part 177c is elastically deformed or bent when the flotation device 170 installed in the river receives pressure more than set due to the flow of river water, etc. As shown in FIG. The support rod 177, the floating body 171, and the floating object guide guide 173 are separated and function to keep the floating support rod 177 and the like supported only on the frame axis 177d in the flow direction of river water. That is, the elastic deformation part 177b or the bending induction part 177c is deformed such that the flotation support rod 177 is reduced, twisted, or bent when the flotation device 170 receives pressure more than set due to the flow of river water, etc. Part 177a becomes unable to maintain the engaged state.

As shown in FIG. 4A, the elastic deformation part 177b includes a spring inside the long bar-shaped floating support bar 177, so the floating support bar 177 can contract in the longitudinal direction by an external force. Due to this structure, the length of the floating support bar 177 can be adjusted.

As shown in FIG. 4B, the bending induction unit 177c includes a folding hinge 177c-1, a folding spring 177c-2 that can elastically press the folding hinge 177c-1 in the longitudinal direction, and a folding hinge (177c-1) is provided with a hinge slot (177c-3) in which a space is formed so that it can be bent while being rotated by an external force. When an external force greater than set by this structure acts, the floating support bar 177 can be bent in the open direction of the hinge slot 177c-3 with the folding hinge 177c-1 as a central axis.

That is, when a large amount of floating matter flows in at once along the flow of river water by the elastic deformation part 177b and/or the bending induction part 177c, the floating matter introduced before reaching the set pressure or more is removed by the flotation device 170 It may lead to the collection device 150.

As shown in FIG. 5, when a pressure greater than that set in the flotation device 170 (see 'Fw' in FIG. 5) is applied due to the river water pressure, the flow of river water, or floating matter, the elastic deformation part 177b causes the flotation support rod ( 177) (see the inclination angle 'A' in FIG. 5) is reduced and the end engagement portion 177a moves downward, and the pair of floating support rods 177 are disengaged and supported by the floating frame 133, respectively. It is located along the stream of river water.

On the other hand, by the operation of the bending induction unit 177c (when the elastic deformation force of the bending spring in the longitudinal direction is overcome by torsion, moment, etc. according to the pressure of river water, etc.), the floating support rod 177 is bent or twisted, and a pair of floating The support rods 177 are bent and disengaged so as to be positioned along the flow of river water while being supported by the floating frames 133, respectively.

That is, according to the present invention, the float can be collected through the flotation device 170 even at a normal water level.

On the other hand, as shown in FIGS. 1 and 2 , the flotation device 170 guides the floating matter introduced along the river water during the initial rain to the collection device 150, and the space formed concavely downstream of the flotation frame 133. When the water level of river water is lowered after being guided to, it can be collected in the collection network 155 through the collection network opening 153 while descending along the water level on the floating frame 133 side.

As described above, the floating matter collected in the collection network 155 can be collected through a known means, such as a vehicle crane, and the collection network 155 can be recycled.

In addition, in the area of the floating object 171 and the floating object guide 173 that come into contact with the floating object floated down from the upstream side of the flotation device 170, even if the floating object is guided to the collection device by the inclination angle, the frictional force with the floating object is reduced to be more effective. Friction reduction of a board with a smooth surface so that the floating object is in contact with the upstream floating object such as the floating object 171 and the floating object guide guide 173 so that the frictional force is reduced and guided to the collection device while sliding. It is preferable to further include a member (not shown).

Accordingly, according to the present invention, it is possible to provide a river floating matter collection system capable of effectively blocking floating matter flowing in from small rivers or tributaries where floating matter, which accounts for most of marine debris, is mainly generated.

In addition, in the process of collecting the floating matter, it is possible to provide a river floating matter collection system capable of collecting the floating matter without a separate power and moving up and down according to the water level change.

In addition, it is possible to provide a river floating matter collection system that can be installed and maintained simply and conveniently at a low cost in small rivers and can collect floating matter during initial precipitation.
