Description

Technical Field

[0001] The present invention belongs to the technical field of water surface fences, and particularly relates to an offshore oil spill fence structure. Background Art

[0002] After an oil spill occurs in the offshore sea area, generally, it is necessary to first enclose and control to limit the spread of the oil spill, and then treat it by physical, chemical, biological and other methods. In physical methods, adsorption materials are mostly used to adsorb, recover and reuse the oil spill, which is an effective method for oil spill disposal.

Detailed implementation manners

[0024] To more clearly elaborate on the structural features and functions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1 - Figure 5, in an embodiment of the present invention, an offshore oil spill containment structure includes a housing member 1, the housing member 1 includes a main housing 101, an inner cavity 102, an inclined groove surface 103, and a liquid guide cavity 104. An inner cavity 102 is disposed inside the main housing 101. An inclined groove surface 103 is disposed on one side of the outer surface of the main housing 101. A plurality of liquid guide cavities 104 are circumferentially disposed in the inner cavity 102. An inlet pipe 105 and a drain pipe 106 are further connected in the liquid guide cavity 104. The end of the drain pipe 106 is disposed on one side of the inclined groove surface 103; a liquid guide assembly 2, the liquid guide assembly 2 includes a piston member 201 and a curved lever arm 202. A plurality of the piston members 201 are respectively slidably assembled in the liquid guide cavities 104, and one end thereof is movably connected to a curved lever arm 202; a driving mechanism 3, the driving mechanism 3 includes a driving rod 301, an impeller 302, a transmission group 303, and a C-shaped shaft rod 304. The driving rod 301 is rotatably assembled on the top of the main housing 101, and an impeller 302 is connected thereto. A transmission group 303 is assembled at the bottom of the driving rod 301. The C-shaped shaft rod 304 is disposed between a plurality of liquid guide cavities 104, and one end thereof is assembled and connected to the transmission group 303, and the other end is assembled and connected to a plurality of the curved lever arms 202 for driving the plurality of piston members 201 to alternately move in the plurality of liquid guide cavities 104; a floating body assembly 4, the floating body assembly 4 includes a floating body member 401 and a suction nozzle 403. The floating body member 401 is disposed at one end of the main housing 101 and is arranged on the side away from the inclined groove surface 103. A plurality of suction nozzles 403 are assembled on the floating body member 401, and the suction nozzles 403 are communicated with the inlet pipe 105; and a lower fence mechanism 5, the lower fence mechanism 5 is disposed at the bottom of the main housing 101 and is linked with the driving mechanism 3 for adjusting the lower fence depth of the fence.

[0026] In practical applications of this embodiment, when using this oil spill fence to enclose the oil leaked on the sea surface, when the device floats on the water surface, one end of the inclined chute surface 103 faces the oil liquid surface. Since the inclined chute surface 103 is an inclined surface, the oil liquid surging onto the surface of the inclined chute surface 103 under the action of ocean waves can flow back to the oil liquid end under the action of gravity. Moreover, when this fence is arranged on the sea surface, the impeller 302 located at the top of the main housing 101 can rotate automatically under the action of sea breeze. During the rotation process, it can drive the drive rod 301 to rotate, and use the transmission group 303 for transmission, so that the C-shaped shaft rod 304 rotates cyclically in the middle of several liquid guide cavities 104. When the C-shaped shaft rod 304 rotates, since several piston members 201 are all movably connected to the C-shaped shaft rod 304 through the curved rod arms 202, several curved rod arms 202 can drive several piston members 201 to reciprocate in several liquid guide cavities 104. When the piston member 201 moves towards one end of the C-shaped shaft rod 304, due to the negative pressure in the cavity of the liquid guide cavity 104, it can suck from one end of the liquid inlet pipe 105, so that the suction nozzle 403 connected to one end of the liquid inlet pipe 105 sucks water from the sea surface end. When the fence structure floats on the sea surface, while enclosing a small amount of oil liquid that penetrates to the other side in the floating body 401, several suction nozzles 403 suck the oil liquid into the interior of the liquid guide cavity 104, and when the piston member 201 slides in the reverse direction, it presses the oil liquid towards one end of the liquid discharge pipe 106, so that the oil liquid flows through the liquid discharge pipe 106 and then flows onto the surface of the inclined chute surface 103. On the one hand, the mixed liquid of oil liquid and water is re-discharged to the oil liquid end, reducing the diffusion of oil liquid on the water surface and reducing the pollution to the natural environment. On the other hand, it can wash the surface of the inclined chute surface 103 and wash the oil liquid adhered to it to the oil liquid end. When the C-shaped shaft rod 304 rotates circumferentially, the lower fence mechanism 5 linked to the C-shaped shaft rod 304 can adjust its extension length through the rotation speed of the C-shaped shaft rod 304, thereby adjusting the depth of the bottom of the fence, so that the fence can adjust its lower fence depth according to the wind speed on the sea surface to resist the action of wind and waves and reduce the probability of oil liquid penetrating from the bottom of the fence.

[0027] In one case of this embodiment, the transmission group 303 can adopt a transmission structure composed of several transmission gears, or a transmission structure composed of a transmission belt, as long as it can make the drive rod 301 and the C-shaped shaft rod 304 rotate at different speeds, so as to reduce the rotation speed of the C-shaped shaft rod 304 end and avoid continuous shaking caused by too fast rotation speed.

[0028] Please refer to Figure 4 , in a preferred embodiment of the present invention, one-way valve ports are assembled on both the liquid inlet pipe 105 and the liquid discharge pipe 106 to limit the movement direction of the fluid.

[0029] In actual application of this embodiment, check valves are assembled on both the liquid inlet pipe 105 and the liquid discharge pipe 106. The check valve on the liquid inlet pipe 105 is used to limit the water-oil mixture to be sucked from one end of the suction nozzle 403 into the liquid guide cavity 104. The check valve on the liquid discharge pipe 106 is used to limit the water-oil mixture to be output from the liquid guide cavity 104 to one side of the inclined groove surface 103, so that during the reciprocating sliding of the piston member 201, several of the liquid guide cavities 104 are always in a continuous suction and discharge state, and the piston members 201 in several liquid guide cavities 104 move alternately, thereby realizing continuous suction and discharge actions.

[0030] In one case of this embodiment, after the water-oil mixture flows to the oil end, due to the different densities of water and oil, natural stratification can occur, so that the water moves to the lower part of the oil layer, and the oil is stably intercepted in this fence.

[0031] Please refer to Figure 2 and Figure 3 , in a preferred embodiment of the present invention, the housing member 1 further includes a liquid discharge nozzle 107 and a sealing cavity 108. The liquid discharge nozzle 107 is assembled at the end of the liquid discharge pipe 106 and is arranged on the top of the inclined groove surface 103, and is used to convey the sucked water in the liquid guide cavity 104 to one side of the inclined groove surface 103.

[0032] In actual application of this embodiment, the liquid discharge nozzle 107 is arranged on one side of the inclined groove surface 103, and the opening direction of the liquid discharge nozzle 107 is arranged close to the surface of the inclined groove surface 103, so that the discharged water-oil mixture flows to the oil end through the surface of the inclined groove surface 103. And since the main component sucked at the suction nozzle 403 end is water, the surface of the inclined groove surface 103 can be flushed and cleaned. The sealing cavity 108 is arranged at the bottom of the main housing 101, and the sealing cavity 108 is in a sealed state, so that the lower fence mechanism 5 does not contact the water body during movement, avoiding affecting its rotation speed.

[0033] Please refer to Figure 2 , in a preferred embodiment of this embodiment, the floating body assembly 4 further includes a float 402 and a flexible connecting pipe 404. The floating body member 401 is slidably assembled at one end of the main housing 101, and several floats 402 are assembled on the floating body member 401. The flexible connecting pipe 404 is assembled between the suction nozzle 403 and the liquid inlet pipe 105 and is used to connect the suction nozzle 403 and the liquid inlet pipe 105.

[0034] In practical application of this embodiment, since the floating member 401 is slidably assembled at one end of the main housing 101, the floating member 401 can continuously float on the sea surface through the float 402 thereon, so that the suction nozzle 403 is always located at the sea surface position, facilitating the suction of the oil seeping from the upper layer of the sea. Moreover, the flexible connecting pipe 404 adopts a hose structure, which can ensure stable connection between the suction nozzle 403 and the liquid inlet pipe 105 when the floating member 401 floats on the sea surface.

[0035] In one case of this embodiment, since the fence structure floats on the sea surface, when the waves drive the fence to move, due to inertia, a gap will be generated between the fence and the sea surface, allowing the oil to flow from the gap to the other side of the fence. Since the floating member 401 has a square-shaped structure, it can enclose the seeping oil again therein, facilitating the suction by the suction nozzle 403.

[0036] Please refer to Figure 3 , in a preferred embodiment of the present invention, the lower fence mechanism 5 includes a rotating body 501, a sliding core 502 and a C-shaped long rod 504. The rotating body 501 is disposed in the sealing cavity 108 and is assembled and connected to the C-shaped shaft rod 304. One end of the rotating body 501 is elastically and slidably assembled with a sliding core 502, and a magnetic body 503 is fixedly assembled on the sliding core 502. Two groups of the C-shaped long rods 504 are slidably assembled on the sealing cavity 108, and a magnetic member 505 is assembled at one end of the C-shaped long rod 504. The magnetic member 505 is arranged on the side facing the sliding core 502. The other end of the C-shaped long rod 504 is assembled and connected with a hinge arm group 506. The hinge arm group 506 is disposed at the bottom of the sealing cavity 108, and a waterproof cloth 508 is assembled on the hinge arm group 506.

[0037] In practical application of this embodiment, during the rotation of the C-shaped shaft rod 304, it can drive the synchronous rotation of the rotating body 501. When the rotating body 501 rotates, the sliding core 502 slidably assembled therein slides towards one end away from the rotating body 501 under the action of centrifugal force, and the magnetic body 503 assembled thereon approaches the magnetic member 505. Under the push of the magnetic force, the C-shaped long rod 504 can overcome the elastic force and slide, so that the C-shaped long rod 504 slides towards one end away from the sliding core 502. During the sliding process of the C-shaped long rod 504, the articulated arm group 506 assembled at the other end thereof starts to expand and contract under the pulling action. When the wind speed on the sea surface is greater and the wave kinetic energy is greater, the rotating speed of the rotating body 501 is faster, so that the distance between the two C-shaped long rods 504 is greater, thereby pulling the articulated arm group 506 to expand, so that the articulated arm group 506 and the waterproof cloth 508 assembled thereon synchronously extend towards the lower end of the water surface, thereby forming a retractable fence structure under the water surface, adaptively adjusting its retractable length according to the size of the wind and waves on the sea surface, and extending its length when the wind and waves are large to prevent the oil liquid from seeping out from the bottom of the fence.

[0038] In one case of this embodiment, the lower fence mechanism 5 further includes a winding cylinder 507, which is arranged at the bottom of the main housing 101 and is assembled and connected with the waterproof cloth 508 for elastically winding the waterproof cloth 508. The winding cylinder 507 can elastically wind the waterproof cloth 508 to facilitate the recovery of the waterproof cloth 508.

[0039] In the above embodiment of the present invention, a marine oil spill fence structure is provided. By means of the main housing 101 floating on the water surface, the natural wind energy on the sea surface can be utilized to drive the liquid guide assembly 2 inside it to continuously move, suck the oil liquid seeping out from one side of the fence and re-discharge it to the oil liquid end, reduce the harm of oil liquid diffusion, and at the same time, the depth of the lower fence can be adaptively adjusted according to the size of the wind and waves on the sea surface to reduce the penetration of oil liquid from the bottom of the fence.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
