Description

Water-jet recovery system of floating matters on the water surface}

The present invention relates to an apparatus for recovering water surface floating water using water spray, and in particular, to remove floating substances such as oil or garbage floating on the surface of lakes, rivers, and the sea using water-floating fluids such as ships or pants. When using the water jet apparatus of the present invention to recover the suspended matter on the surface of the water by collecting the floats farther than the width of the ship in the width of the ship while increasing the recovery amount of additional additional resistance or The present invention relates to a surface floating water recovery apparatus using water spray, which can smoothly perform a recovery operation without reducing a ship speed. In addition, the present recovery device can be easily loaded to recover the suspended matter without greatly modifying the existing vessel.

Generally, a variety of float recovery devices have been developed in rivers, lakes, and seas to recover a lot of naturally or artificially generated floats. However, ships, such as ships or pants, have to move forward or turn and overcome the water resistance. Is designed to be as small as possible. Therefore, in the case of single or double catamarans, the additional work is added to recover the floats, and the working width increases, but the resistance of the ship increases and the propulsion speed decreases. The amount to recover the suspended matter is reduced.

In addition, the existing float recovery devices have the effect of broadening the recovery range by recovering the floats on the water in the bow or the center of the ship to the funnel by contacting the side of the side with the side guides such as the guide plate. When the adjoining adjunct is installed, the resistance of the water increases, resulting in a slower ship's forward speed, so that the amount of suspended matter recovery per unit time does not increase at all. In addition, the installation of these adjuncts increases both the amount of incoming waves and the amount of water, and thus requires a sofa device to reduce the waves, as well as the task of separating the increased water from the suspended solids. There was a problem that occurs more severely.

In addition, as shown in Figure 1 as a plan view of a conventional surface flotation recovery apparatus using air spray, Korean Patent Publication No. 97-15401 dated April 28, 1997 (Application No. 95-29649: 1995.09.06 The present invention relates to a control vessel disclosed in the above), which is provided with a plurality of air injection nozzles 26 in an inward direction of a ship and supplies or blows compressed air to an air compressor, or air discharged from an air injection nozzle 26. Since it diffuses rapidly in the air, the moment velocity of water reaches the surface becomes very slow and weakened, so that the effect of moving the float is very small. In addition, the gap between the injector and the surface should be sufficient for digging more than the distance between the injector and the surface. Is less, and there is a problem that there is little work effect, especially in a windy state.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, by injecting and compressing the water around the ship by spraying the high-pressure, high-speed water to push the floating surface on the water inside the recovery device per unit time of the ship It is to provide a device using water spray to increase the recovery amount of the suspended matter, more specifically, in the water floating object recovery device is installed on the deck of the ship, the suction pipe installed in the center of the front of the deck is introduced into the water A pressurized pump that sucks water from the water through the water spray nozzles installed in the discharge pipes on both sides of the water, and a control panel that controls the pressurized pump, a generator that provides driving power to each device, and rotates the discharge pipe.

Hereinafter, an embodiment according to the spirit of the present invention configured as described above will be described in detail with reference to the accompanying drawings. Figure 2 is a working state diagram using the apparatus of the present invention, Figure 3 is a perspective view and a cross-sectional view of the guide rail of Figure 2, Figure 4 is a state diagram equipped with the apparatus of the present invention, Figure 5 is a cradle of Figure 4 Perspective view.

First, referring to the basic configuration from Figure 2, the system of the present invention can be divided into a spraying operation and a recovery operation largely in order to effectively remove the suspended matter in the water, the injection. Induction working unit is installed in front of the vessel 100 It consists of the suction pipe 1, the pressure pump 2, the discharge pipe 3, the water injection nozzle 4, the operation panel 5, the generator 7, etc.

The pressurized pump (2) is installed in the center of the deck front and is operated by the operating panel (5) and the generator (7) is connected to the bottom to suck water from the suction pipe (1) introduced into the water discharge pipes of both sides ( 3) When the water is pressurized and discharged, the discharge pipes 3 on both sides protruding radially from the vessel are provided with a plurality of water spray nozzles 4 on one side and are fan-shaped toward the floats on the surface of the water at high pressure and high speed. Inject the floats to the inside of both vessels. In addition, the recovery work unit at the rear of the hull is provided with a funnel-shaped collecting device 10 made of a screen or the like and a lifting pump 12 for suctioning and lifting the collected suspended matter at the center of the upper hull of the collecting device 10. The pump 12 feeds the lifted floating material to the storage 13 installed on the deck 200 through the lifting pipe 11.

More specifically, the end of the suction pipe (1) is installed deep enough to be below the water surface in any movement state of the ship serves as a transport pipe from the water to the pressure pump (2). When the pressure pump 2 is operated, the water in the lower part of the hull is lifted up through the suction pipe 1, and the water compressed by the pressure pump 2 is used for water injection through the discharge pipe 3 installed in the port and starboard. It is transported up to the nozzle 4 and sprayed onto the surface as it is accelerated and diffused in the nozzle. The sprayed water slows down when it hits the surface, causing the float to rush into the interior of both hulls. A plurality of nozzles 4 are installed in the discharge pipe 3 installed in a radial shape, and thus, the suspended matter on the water surface can be collected in a wider range than the width of the vessel 100 due to the continuous water spraying effect. The water spray nozzle 4 converts the energy of pressurized water into velocity energy through a small hole and sprays it at a high speed. When the sprayed water particles come into contact with the surface of a lake or the sea, the speed drops sharply and floats on the surface of the water. The direction of the nozzle should be slightly inclined from the vertical direction to the ship's hull centerline as it must be guided and moved.

The pressurized pump 2 selects seawater or fresh water (land) according to the type of working fluid, and the capacity of the pressurized pump is selected in consideration of the moving speed, the head loss of the pipe, and the water spraying speed during the operation of the floating body. do. In addition, the pressurized pump 2 uses electricity inside the ship or loads a separate generator 7 to be driven.

The discharge pipe 3 gradually decreases in diameter toward the front end, thereby achieving convenience of work with reduction of weight. In addition, the shape of the cross section of the nozzle 4 is elliptical, and the shape of the water sprayed from the nozzles becomes a fan-shaped shape, so that the floating water can be prevented from leaking out. The control panel 5 supplies electric power supplied to various pumps. It is a control device that starts / stops the pump by blocking it.

In addition, the floats pushed into the width of the vessel is gathered by the float collecting device 10 located in the rear of the water spray device and located near the water surface, and through the pipe 11 through the pump for lifting floats 12. Enter the reservoir (13). The floating reservoir 13 may use a separate tank or may use a dock inside the ship as it is.

As shown in a perspective view and a cross-sectional view of the guide rail of FIGS. 3a and 3b, the discharge pipe 3 is a cantilever that must serve to transfer the water compressed in the pressure pump 2 to a nozzle unit far from the hull. A deflection prevention support 9 is installed to prevent deflection. The cross-sectional area of the discharge pipe 3 is made as large as possible to reduce pressure loss. In order to facilitate the rotation of the reinforced discharge pipe 3 and to support the load in the vicinity of the rotation hinge 8 of the discharge pipe 3 protruding forward and to which the support 9 for deflection is attached, a curve having a constant radius is used. Install the guide rail (14). In addition, the guide rail 14 has a plurality of fixing holes 15 formed therein so as to correspond to the holes of the fixing plate 16 protruding to one side in the lower portion of the discharge pipe 3 and fixing pins. It can be fixed by (17). And, in order to firmly prevent the separation of the fixing pin 17 due to the movement of the ship, a hole is formed at one end so that the cutter pin 17-1 (Cutter Pin) for preventing the departure is inserted.

In addition, as shown in Figures 4 and 5, when not collecting the float, the discharge pipe (3) with the nozzle (4) is attached to the cradle near the athlete in order to minimize the storage space and promote safety by water movement ( 18) so that the end of the discharge pipe (3) can be settled. In order to prevent damage caused by the water movement of the ship, the port structure is fixed to the starboard and the port structure is fixed to the port. At this time, since the structure is higher than the deck of the ship to install a cradle (18: Rest) in each side to securely fixed. The cradle 18 is a horseshoe shape, the upper side of the both sides is provided with a through hole so that the fixing pin (18-1) is inserted and the fixing pin (18-1) is formed at one end of the hole to prevent separation The cutter pin 18-2 is installed to be inserted to prevent the structure from being released from the cradle 18 by the movement of the ship. In addition, in order to prevent structures such as the support 9 on the port side and the starboard side from interfering with each other, the heights of the rotation hinges 8 and the height of the cradle 18 on the port side and the starboard side are different from each other. do. Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
