Description

Skimmer {Skimmer}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skimmer, and more particularly, to a skimmer which is introduced into a sea or fresh water to recover an effluent or suspended matter.

Recently, frequent marine casualties have caused pollution and pollution of the sea by polluting the oceans with oil flowing from the vessels. In addition, suspended matter is continuously generated in rivers, rivers or wastewater purification facilities. Various devices have been developed to recover such effluents or suspensions. Among these devices, there are weir type skimmer and drum type skimmer as devices for recovering effluent oil, and techniques for recycling waste oil of oil tankers and the like and sucking the effluent oil directly to the ship are already utilized.

However, in particular, it is necessary to quickly remove the oil that is leaked in the event of a marine accident. Conventionally, it is necessary to spray the oil treatment agent to the polluted area by an airplane or a ship or to install an oil fence, Type skimmer or drum-type skimmer into the contaminated area to recover the effluent oil. Spraying the oil treatment agent causes another environmental pollution, and conventional weir type skimmer and drum type skimmer have a disadvantage in that the volume is generally large and the convenience of transportation is poor.

Therefore, it is urgent to develop a skimmer that can be quickly transported to the accident site.

In addition, the embodiment described below does not unduly limit the content of the present invention described in the claims, and the entire structure described in this embodiment is not necessarily essential as the solution means of the present invention.

< Effluent Or suspension recovery device>

According to an embodiment of the present invention, an effluent or scum collecting apparatus is an apparatus for collecting effluent oil or suspended matters floating on a surface of a water, which is inputted into a sea, a river, a river, For example, in the case of oceans, oil spilled out (hereinafter referred to as spilled oil) is recovered in the case of oil spill due to a ship accident, and in the case of waste water treatment plants, spoil floating on the water surface is recovered. In the case of a river or a river, tadpole eggs and the like can be recovered. As described above, the effluent or scum collecting apparatus according to an embodiment of the present invention recovers the effluent or suspended matter scattered thinly on the water surface with a water content as low as possible. In an embodiment of the present invention, the oil or skimmer collecting device will be described as an oil skimmer. However, as described above, all the oil or suspended matter floating on the surface of the sea or fresh water can be recovered.

As shown in FIG. 1, the oil skimmer 10 according to the embodiment of the present invention recovers oil that has leaked when a ship accident occurs in the sea (or in the event of an accident). The oil skimmer 10 is introduced into the oil spill area and sucks out the oil spilled on the interface with the sea water (the oil spilled into the sea due to a marine accident). At this time, when the oil skimmer 10 collects the effluent oil, the space for storing the recovered oil is limited, so it is necessary to reduce the water content as much as possible. This is because the return oil sucked and recovered by the oil skimmer 10 is delivered to the bus (a ship carrying the oil skimmer) by pumping. At this time, when the water content becomes high, sea water is stored in the recovered milk and is inefficient.

As shown in FIG. 1, the oil skimmer 10 according to an embodiment of the present invention for minimizing the water content is provided with a support body 100, a buoyant body 200, a oil collecting part 300, and a fixing part 400 Lt; / RTI > Since this distinction is for convenience of description, the technical idea of the present invention is not limited by the reference numerals and the divided configurations.

FIG. 1 is a view showing a buoyant body expanded when an oil skimmer 10 according to an embodiment of the present invention is recovered. FIG. 2 is a structure in which a buoyant body is folded to maximize the convenience of transportation. The oil skimmer 10 normally folds the buoyancy body as shown in Fig. 2 and stores it. When entering the oil spill area due to marine accidents, the oil skimmer must be moved using the bus, so the volume should be small and the weight should be small. Therefore, by folding and moving the buoyant body of the oil skimmer of the present invention, a person can be moved easily. In addition, as described later, the members of the oil skimmer are integrated with each other and made of a light material, so that the weight can be reduced and the production yield can be improved.

As shown in FIG. 3, the support 100 according to an embodiment of the present invention has a substantially 'circular shape' in cross-sectional shape, and has a three- As shown in Fig. The coupling portion may include first, second, and third direction coupling portions 110a, 110b, and 110c. The first, second, and third direction coupling portions 110a, 110b, 110c are each extended and protruded from the center region at an angle of about 120 degrees. However, it is needless to say that the coupling portion may be formed in two directions or four or more directions as necessary, and the coupling portion may be formed corresponding to the directionality.

As shown in FIG. 3, the protruding portion 113 of the first direction coupling portion 110a is formed with a buoyant body coupling groove 111 for coupling with a first buoyant body 210 described later, A bolt protector (not shown) is inserted into the groove 111, and the fixing portion 111b is inserted into the bolt protector as shown in FIG. 4 to engage with the first buoyant body 210. At this time, the fixing portion 111b may be a bolt and a nut. The first direction coupling part 110a is formed with a buoyant body coupling groove 111 and the first buoyant body 210 to be described later is formed to correspond to the support coupling engagement groove 211. [ The first buoyant body 210 is fixed to the buoyant body engagement groove 111 by the fixing portion 11b inserted into the support member engagement groove 211 so that the first buoyant body 210 moves downward . &Lt; / RTI >

As shown in FIG. 3, a seating part 112 is formed in the first direction coupling part 110a. The right seating part 112a and the left seating part 112b are formed on both sides of the substantially end of the projection 113 protruding from the center area of the first direction coupling part 110a. The first float body 210, which will be described later in correspondence with the protrusion 113 protruding in the longitudinal direction, is provided with a groove 212 having a substantially "C" shape at the end of the coupling portion to be engaged with the support, 212 are fitted with protrusions 113.

The seat portion 112 is a space in which the first buoyant body 210 is seated as shown in FIG. 4 when the buoyant body 200 described later is deployed. 3, the upper surface 112a-1 of the right seating portion 112a is formed on the lower side with respect to the surface of the protrusion 113, and the protrusion length of the upper surface 112a-1 is less than that of the protrusion 113 Respectively. The upper surface 112a-1 is where the first buoyant body 210 is seated when unfolded. The side face 112a-2 of the right seating portion 112a is a side face formed by being bent downward from the longitudinal protrusion end of the upper face 112a-1 as shown in Fig. Thus, the top and sides are formed with approximately '┌' characters. The side face 112a-2 of the right seating portion 112a can adjust the angle of folding as shown in Fig. 5 when the first buoyant body 210 is folded. Fig. 4 is a view when the first buoyant body 210 is unfolded. Fig. 5 is a view when folded. When the side is formed substantially vertically as shown in Fig. 5, The angle of folding of the first buoyant body 210 can be made to be folded more or less than 90 degrees. Therefore, the side surface 112a-2 of the right seating portion 112a serves as a stopper for adjusting the angle of folding of the first buoyant body 210. [ The left seating portion 112b has the same configuration as that of the right seating portion 112a. Therefore, when the first buoyant body 210 is unfolded, the protruding portion 113 is fitted into the groove 212 of the first buoyant body, and the first buoyant body 210 is seated on the right and left seating portions 112a and 112b It is spread horizontally roughly. At this time, the horizontal angle adjustment is adjusted along the left and right upper surfaces of the seating portion 112. That is, by adjusting the inclination of the upper surface, the angle when the first buoyant body 210 is unfolded can be adjusted.

However, the configuration of the first directional coupler 110a may be applied to the configurations of the remaining second and third directional couplers 110b and 110c, The second directional coupler 220 and the third directional coupler 110c may be coupled to each other.

As shown in FIG. 3, rod-engaging fixing grooves 122 are formed in protrusions of the first, second, and third direction coupling portions 110a, 110b, and 110c, respectively. The first, second, and third rods 420, 430, and 440 are inserted into the rod coupling groove 122. A center rod fixing groove 121 is formed in the center of the supporting body 100, and a center rod 410 is inserted.

As shown in FIG. 6, a center rod fixing groove 121 described later is formed in a substantially central region of the support 100. A center rod 410 to be described later is inserted and fixed in the center rod fixing groove 121. 3 and 6, a first rod engaging fixing groove 122a is formed in the protrusion 113 of the first direction engaging portion. A first rod 420 to be described later is inserted and fixed in the first rod engaging groove 122a and a second rod and a third rod 430 and 440 are inserted into protrusions of the second and third direction coupling portions 110b and 110c And the engagement fixing grooves 122b and 122c to be inserted and engaged are formed.

The buoyant body 200 according to an embodiment of the present invention is as shown in FIG. 7, and the first buoyant body 210 will be described below. The explanation of the second and third buoyant bodies 220, The description of the buoyancy member 210 will be omitted. As shown in FIG. 7, the first buoyant body 210 is formed with a support engaging groove 211 for fixing the first buoyant body 210 to the first direction engaging portion 110a of the support body. The fixing portion 111b shown in FIG. 4 is inserted into the support-engaging fixing groove 211 and the buoyancy-body engaging and fixing groove 111, and fixed to each other. The substantially U-shaped groove 212 formed in the first buoyant body 210 is a groove into which the protruding portion 113 of the first directional coupler 110a is fitted. The groove 212 is formed in the center region of the substantially end surface of the coupling region 213 where the first buoyant body 210 is engaged with the first direction coupling portion 110a so as to correspond to the projection 113 in the longitudinal direction Grooves are formed. The coupling region 213 refers to a region of the edge where the buoyant body is coupled with the support.

As shown in FIG. 7, the first buoyant body 210 is wider as the buoyant body is further away from the engagement region 213 in the longitudinal direction of the buoyant body. This is because the buoyancy is maximized by enlarging the surface area touching the water of the buoyant body and the width of the buoyant body is wide, so that the balance can be maintained stably irrespective of the sea crest. In addition, the coupling region 213 of the buoyant body 200 does not touch the water surface, and the region opposite to the coupling region 213 contacts the water surface to maintain the buoyancy in three directions. Thus, the engagement region 213 of the buoyancy member is relatively narrow and the opposite side of the engagement region 213 is formed to be relatively wide.

When the buoyant body 200 is folded as shown in FIG. 2 in order to reduce the volume of the oil skimmer 10 and is introduced into the outflow oil recovery area, the buoyant body 200 is separated from the water surface of the seawater as shown in FIG. It automatically or manually unfolds. When the oil skimmer 10 is automatically folded, when the oil skimmer 10 folded on the bus line is thrown into the sea, the oil skimmer 10 is automatically unfolded along the surface of the water as shown in Fig. 1 (unfolded) .

The collecting part 300 according to an embodiment of the present invention includes an upper support 310, a bellows 320, a lower support 330, and a sieve 600, as shown in FIG. 8 and 9, the buoyancy is maintained because the inside of the upper support 310 is formed of a hollow material and can be floated on water. When the bellows 320 described below enters the water, the folded bellows 320 ) Can be expanded. That is, the above-described buoyant body 200 provides total buoyancy of the oil skimmer 10 and the upper support 310 provides buoyancy such that the bellows 320 can be unfolded. As shown in FIG. 9, the upper support 310 has a center rod through groove 311 through which the center rod 410 passes. Thus, the upper support 310 can be moved up and down along the center rod 410 with respect to the support 100 and the lower support 330. As shown in FIG. 9, the upper support 310 has a circular shape in cross section, and is formed by hollowing two-thirds of the central region from the central region. The outer portion of the upper support 310 is covered with a bellows 320 A support frame 312 is integrally formed in three directions from the central region at an angle of approximately 120. A center rod penetrating groove (not shown) is formed on the central portion of the support frame 312, The upper surface 314 of the upper support 310 is formed higher than the lid 313 so that the water surface 20 is substantially flush with the upper surface 314 as shown in FIG. And the effluent oil is sucked over the top surface 314. The upper support 310 described above thus provides a self-buoyancy (independent buoyancy) to the bellows 320 separately from the buoyancy member 200, So that the top surface 314 of the upper support remains horizontal with the water surface The.

The bellows 320 according to an embodiment of the present invention is folded at normal times and is stretched downwardly and downwardly by the buoyant force of the upper support 310 at the time of recovering the outflow oil. When the upper support 310 providing its own buoyancy provides buoyancy in accordance with the waves, the bellows 320 is elastically stretched and contracted in the vertical direction. The bellows 320 is wrapped around the lid portion 313 of the upper support and the lid portion 334 of the lower support described later. So that the upper support 310 can be stretched as much as it provides buoyancy. That is, when the water suddenly rises and a lot of water overflows to the upper surface 314 of the upper support 310, the buoyancy of the upper support 310 is lowered so that the upper support 310 does not go below the surface of the instant water and the bellows 320 is folded . Thereafter, the upper support body 310 recovers buoyancy by its own buoyancy and keeps it horizontal with the water surface 20.

The collecting part 300 according to an embodiment of the present invention is formed at a lower part of the support 100 and is provided inside a virtual circle in which first, second and third rods 420, 430 and 440 are disposed. Also, the folded buoyancy body 200 is folded in the vertical direction at approximately the same position as the first, second, and third rods 420, 430, and 440 as shown in FIG.

The lower support 330 according to an embodiment of the present invention is positioned below the bellows 320 and the center rod fixing groove 331 to which the center rod 410 is fixed as shown in FIG. do. The lower support 320 is approximately "circular ", with the groove 335 being about 3/4 of the center area. Outflow oil sucked by the dug groove 335 and the bellows 320 is collected. As shown in FIG. 10, a cover 334 is formed on the outer frame so that the bellows 320 can be covered. A return oil discharge portion 333 is formed at one side of the lower portion of the lower support 330 below the lid portion 334. Thus, although not shown in the present invention, a pump is disposed in the vicinity of a bus bar or oil skimmer to pump return oil.

A coupling portion 332 for coupling with the first rod 420 is formed on the lower surface of the peripheral region of the lower support 330. The engaging portion 332 includes a first rod engaging groove 332a, a first rod engaging portion 332b, and an engaging groove 332c. The first rod 420 is inserted into the coupling groove 332c and the coupling groove formed in the first rod 420 and the first rod coupling groove 332a are formed to correspond to each other, And is engaged and fixed by the engaging portion 332b. The first rod engaging portion 332b may be formed of a bolt and a nut. The engaging groove 332c is formed to face the central portion of the lower support 330 as shown in Fig. Accordingly, the engaging groove 332c is formed in the direction of approximately 120 degrees so that the first, second, and third rods 420, 430, and 440 are inserted, respectively. The coupling portion 332 of the lower support 330 described above is described for coupling the first rod 420. Although not shown in the drawing, the coupling portion 332 is formed in three places in the direction of about 120 degrees, 1, 2 and 3 loads 420, 430 and 440, and further explanation will be omitted from the above description.

The sieve 600 according to one embodiment of the present invention filters suspended matter or debris contained in the effluent flowing along the upper surface 314 of the upper support. Accordingly, the size of the mesh formed in the screen 600 can be varied depending on the place of use. The screen 600 is disposed at a constant height between the bellows 320 and the upper support 310.

The fixing unit 400 according to an embodiment of the present invention fixes the support 100 and the lower support 330 as shown in FIGS. The fixing portion 400 is formed of the center rod 410 and the first, second, and third rods 420, 430, and 440. The center rod 410 is located in the central region with respect to the first, second, and third rods 420, 430, and 440 and includes a center rod fixing groove 121, a center rod through groove 311, And inserted into the groove 331. The first, second, and third rods 420, 430, and 440 are coupled and fixed at a position of about 120 degrees outward about the center rod 410. The first, second and third rods 420, 430 and 440 are bent in a 'C' shape so as to be inserted into the coupling groove 332c of the lower support 330.

As shown in FIG. 12, the first height adjuster 520 is inserted into the first rod 420 to adjust the height of the bolt 520. The height adjuster 520, And a coupling portion 521 made up of a nut and a coupling groove, thereby adjusting the height. On the other hand, the first rod 420 is formed of two or more folded folded structures or two or more separated folded types and can be stretched or shrunk in the longitudinal direction when the height is adjusted. On the upper side of the first height adjuster 520, there is formed a hook 522 which can be used to lift the skimmer by a crane or the like. A cable may be connected to the hook 522 to move the skimmer to the crane. Although only the first height adjuster 520 has been described above, the second and third height adjusters 530 and 540 can be explained on the same principle.

FIG. 13 shows that the support 100 is located at a lower position relative to FIG. 14, and when it is desired to move the support 100 upward, the bolts and nuts of the coupling portion 521 are unlocked, (100) is moved upward and the engaging portion (521) is locked again to adjust the height.

The support 100, the buoyant body 200, the upper support 310 and the lower support 330 of the collecting part are made of polyethylene or polypropylene. The bellows 320 is made of rubber, and the fixing part 400 ) Is made of stainless steel. The support body 100, the buoyant body 200, the upper support body 310, and the lower support body 330 are formed into the same material, thereby increasing the production efficiency and reducing the manufacturing cost. The return oil discharge portion 333 is assembled to the lower support 330 by heat fusion processing.

Figs. 15 and 16 show the connection rings 710, 720 and 730 connecting the buoyancy body 200. Fig. The first buoyant body 210 and the second buoyant body 220 are connected by a first connection ring 710 and the second buoyant body 220 and the third buoyant body 230 are connected by a second connection ring 720 , And the third buoyant body (230) and the first buoyant body (210) are connected by a third connection ring (730).
