Description

Technical Field

[0001] This invention relates to the field of offshore operation equipment technology, and in particular to a collision avoidance device that can reduce the impact of waves on offshore operation platforms. Background Technology

[0002] Offshore platforms are truss-structured structures that rise above sea level and have a platform surface, used for production operations or other activities. Based on whether their location is fixed, they are divided into fixed offshore platforms and floating offshore platforms. A floating offshore platform is a floating body placed on the sea surface, typically supported by buoys. These platforms are commonly used for extending wharves, constructing maintenance platforms, and serving as carrier platforms for offshore wind power generation. However, these floating offshore platforms suffer from significant rocking due to the impact of sea waves, and their edges are prone to corrosion and wear, reducing their lifespan. Excessive waves also pose significant safety hazards for those working on the platform, reducing the safety factor. Therefore, a protective device to prevent wave impact is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a collision avoidance device that can reduce the impact of ocean waves on offshore operating platforms.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is: a collision avoidance device for an offshore platform, comprising a floating offshore platform, characterized in that: wave-damping components and wave-blocking components are arranged outward from the edge of the floating offshore platform, and multiple sets of the wave-damping components and the wave-blocking components are horizontally arranged around the floating offshore platform; the wave-damping components are used to reduce the impact of waves on the floating offshore platform, and the wave-blocking components are used to prevent waves from splashing onto the upper surface of the floating offshore platform; the wave-damping components are located between the wave-blocking components and the floating offshore platform.

[0005] Preferably, the wave-damping component includes a blocking body with one side sloped, the slope angle of the blocking body gradually increasing upwards, and the slope angle eventually exceeding 90°. Multiple wave-filtering ports are evenly arranged horizontally in the middle of the blocking body. The wave-filtering ports are rectangular openings with a horizontal length direction. The internal channels of the wave-filtering ports are wave-shaped and penetrate through the blocking body. A float is arranged below the blocking body. One side of the blocking body is connected to the floating offshore platform via a telescopic rod. The distance between the wave-damping component and the floating offshore platform is controlled by the telescopic rod.

[0006] Preferably, a wave-blocking net is provided below the main blocking body, and the wave-blocking net is arranged around the floating offshore platform; the wave-blocking net is fixed to the seabed by an anchor body provided below.

[0007] Preferably, the wave-damping component includes a first buffer box, with a buffer push plate extending from one side of the first buffer box. The buffer push plate has a semi-circular cross-section with the semi-circular opening facing the outside of the floating offshore platform. The buffer push plate is connected to the inside of the first buffer box via a push rod. A buffer pile is connected to the side of the push rod that extends into the first buffer box. The buffer pile is slidably disposed inside the first buffer box and consists of two cylindrical sections with different diameters. The section with the larger diameter acts as a slider and slides with the inside of the first buffer box. An elastic component is sleeved on the outside of the buffer pile.

[0008] Preferably, the opening direction and number of the buffer push plate correspond to the position and number of the filter outlets.

[0009] Preferably, the elastic member is a pressure spring that provides outward pushing force to the buffer push plate. One end of the pressure spring is fixedly connected to the buffer pile, and the other end is fixedly connected to the other side of the first buffer box. A damping buffer device is provided inside the buffer pile.

[0010] Preferably, a second buffer tank is also provided between the first buffer tank and the floating offshore platform. The first buffer tank and the second buffer tank are fixedly connected, and the interior of the second buffer tank is hollow. A bladder is provided inside the second buffer tank, and the bladder is fixed inside the second buffer tank by a support frame. A connecting pipe is provided below the bladder to communicate with the outside of the second buffer tank. A compression rod is provided on the buffer pile, which slides through the first buffer tank and the second buffer tank, and the compression rod contacts the bladder.

[0011] Preferably, the second buffer box is inside a vacuum, the first and second buffer boxes are provided with sealing rings at the portions through which the compression rod passes, and the bag is provided with water or air.

[0012] Preferably, a drainage plate and a float are provided below the first and second buffer tanks; the drainage plate is provided with a drainage channel that communicates with a connecting pipe below the bag, the outlet of the drainage channel faces the direction of the waves, and a sealing valve is provided between the connecting pipe and the drainage channel.

[0013] Preferably, the second buffer tank is provided with a connecting plate between the floating offshore platforms. One side of the connecting plate is fixedly connected to the second buffer tank, and the other side is connected to the side wall of the floating offshore platform by bolts, nuts or chains.

[0014] The present invention has the following beneficial effects: By installing such a collision avoidance device on the outer side of the offshore platform, the arc-shaped wave-damping component initially prevents waves from directly impacting the main body of the offshore platform. At the same time, excessively high waves are also blocked by the wave-damping component, minimizing the splashing of seawater onto the platform. Under the action of the wave-damping component, the waves buffered by the wave-damping component are further buffered. When the waves are too large, they impact the buffer push plate, which in turn squeezes the bag. The seawater stored in the bag is ejected against the direction of the waves, further reducing the wave size. The wave-damping net installed below the wave-damping component can also further reduce the impact of underwater currents on the floating body below the offshore platform, thereby improving the service life of the offshore platform.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0021] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0022] according to Figures 1-3 The diagram illustrates a collision avoidance device for an offshore platform, comprising a floating offshore platform 1. Wave-damping components 2 and wave-blocking components 3 are arranged outwards from the edges of the floating offshore platform 1. Multiple sets of the wave-damping components 2 and the wave-blocking components 3 are horizontally arranged around the floating offshore platform 1. The wave-damping components 2 are used to reduce the impact of waves on the floating offshore platform 1, and the wave-blocking components 3 are used to prevent waves from splashing onto the upper surface of the floating offshore platform 1. The wave-damping components 2 are located between the wave-blocking components 3 and the floating offshore platform 1.

[0023] Furthermore, the wave-blocking component 3 includes a blocking body with one side being a slope, the slope angle of the blocking body gradually increasing upwards, and the slope angle eventually exceeding 90°. Multiple wave-filtering ports 303 are evenly arranged in the middle of the blocking body along the horizontal direction. Each wave-filtering port 303 is a rectangular opening with a horizontal length direction. The internal channel of each wave-filtering port 303 is wave-shaped and penetrates through the blocking body. A float 304 is arranged below the blocking body. One side of the blocking body is connected to the floating offshore platform 1 via a telescopic rod 305.

[0024] Specifically, the arc of the wave-damping component 3 is greater than 90° to prevent excessively large or high waves from passing over it and landing on the floating platform 1. The height of the wave-damping component 3 in the water should be slightly higher than the height of the platform. Simultaneously, to avoid the wave-damping component 3 directly bearing all the impact of the waves and reducing its service life, some waves pass through the wave-filtering port 303. Furthermore, the waves pass through the wave-shaped channel, further reducing their impact force. The distance between the wave-damping component 3 and the floating platform 1 is controlled by the telescopic rod 305.

[0025] Furthermore, according to claim 1, a collision avoidance device for an offshore platform is characterized in that: a wave-blocking net 301 is provided below the blocking body, and the wave-blocking net 301 is arranged sequentially along the wave-blocking member 3; the wave-blocking net 301 is fixed to the seabed by an anchor body 302 provided below.

[0026] Specifically, the wave-damping net 301 extends deep into the water. In deep water areas, it can be supported by the anchor body 302 fixed to the seabed, thereby reducing the impact of seawater currents on the floating body of the floating offshore platform 1. In shallow water areas, the anchor body 302 can be replaced with a bolt and nut structure to directly fix the wave-damping net 301 to the seabed.

[0027] Furthermore, the wave-damping component 2 includes a first buffer box 203, with a buffer push plate 201 extending from one side of the first buffer box 203. The buffer push plate 201 has a semi-circular cross-section with the semi-circular opening facing the outside of the floating offshore platform 1. The buffer push plate 201 is connected to the inside of the first buffer box 203 via a push rod 202. The push rod 202 extends into one side of the first buffer box 203 and is connected to a buffer pile 204. The buffer pile 204 is slidably disposed inside the first buffer box 203. The buffer pile 204 is composed of two cylindrical sections with different diameters. The section with the larger diameter acts as a slider and slides inside the first buffer box 203. Therefore, an elastic component 205 is sleeved on the outside of the section with the smaller diameter.

[0028] Specifically, to prevent the spray from the wave filter 303 of the wave-blocking component 3 from directly impacting the surface of the floating offshore platform 1, a wave-damping component 2 with a buffer pusher 201 is installed behind the wave-blocking component 3. The buffer pusher is not limited to a semi-circular arc-shaped plate; it can also be an arc-shaped plate or a folded plate with a larger angle, which facilitates the complete absorption of the impact force of the waves and converts it into a thrust on the pusher 202. The pusher 202 acts directly on the buffer unit inside the first buffer box 303. In addition to using the buffer pile 204 and subsequent structures, the buffer unit can also use existing shock absorbers or spring damping structures. In particular, the interior of the first buffer box 203 is kept sealed to prevent seawater from entering and affecting the service life of the internal elastic component 205.

[0029] Furthermore, the elastic member 205 is a pressure spring that provides outward pushing force to the buffer push plate 201. One end of the pressure spring is fixedly connected to the buffer pile 204, and the other end is fixedly connected to the other side of the first buffer box 203. A damping buffer device is provided inside the buffer pile 204.

[0030] Furthermore, the opening direction and number of the buffer push plate 201 are made to correspond to the position and number of the wave filter 303, and the telescopic rod 305 is adjusted according to the size of the waves, so as to ensure that the waves output from the wave filter 303 can accurately hit the buffer push plate 201.

[0031] Furthermore, to cope with sufficiently large waves, a second buffer box 206 is also provided between the first buffer box 203 and the floating offshore platform 1. The first buffer box 203 and the second buffer box 206 are fixedly connected, and the interior of the second buffer box 206 is hollow. A bag 207 is provided inside the second buffer box 206. The bag 207 is fixed inside the second buffer box 206 by a support frame 209. A connecting pipe is provided below the bag 207 to communicate with the outside of the second buffer box 206. A compression rod 208 is provided on the buffer pile 204, which slides through the first buffer box 203 and the second buffer box 206. The compression rod 208 contacts the bag 207.

[0032] Specifically, the second buffer box 206 maintains a vacuum state inside, allowing the bag 207 to remain inflated due to the pressure difference between the inside and outside when it is not squeezed by the compression rod 208. When the push rod 202 is forced to compress the buffer pile 204, the buffer pile 204 slides within the first buffer box 203, pushing the compression rod 208 to compress the bag 207. The bag 207 absorbs the thrust and is compressed and reduced in size.

[0033] Furthermore, the second buffer box 206 is internally vacuumed, and the portions of the first buffer box 203 and the second buffer box 206 through which the compression rod 208 passes are equipped with sealing rings. The bag 207 contains water or air. Of course, the compression rod 208 and other sliding components can be coated with lubricating oil to ensure stability and sealing effect when components slide.

[0034] Furthermore, a drainage plate and a float are provided below the first buffer box 203 and the second buffer box 206; the drainage plate is provided with a drainage channel 211 that is connected to the connecting pipe below the bag 207, the outlet of the drainage channel 211 faces the direction of the waves, and a sealing valve 210 is provided between the connecting pipe and the drainage channel.

[0035] Specifically, seawater is directly filled into the bag 207. When the bag 207 inflates, it absorbs seawater from the drainage channel 211. When the bag 207 is impacted and squeezed by waves, the seawater in the bag 207 absorbs the thrust and is pushed out from the drainage channel 211, counteracting the undercurrent and reducing its impact. A sealing valve 210 is installed to control the discharge rate of seawater from the bag 207 and to completely seal the bag 207, allowing it to rely solely on its own elasticity for cushioning.

[0036] Furthermore, the second buffer tank 206 is provided with a connecting plate 212 between the floating offshore platform 1. One side of the connecting plate 212 is fixedly connected to the second buffer tank 206, and the other side includes, but is not limited to, fixing the side wall of the floating offshore platform 1 with bolts and nuts or movably connecting it to the side wall of the floating offshore platform 1 using chains.

[0037] Furthermore, the second buffer box 206 is a long strip box surrounding the outside of the floating offshore platform 1, and the bladder provided in the second buffer box 206 is a horizontally arranged long strip bladder; multiple first boxes 203 are evenly connected to the other side of the second buffer box 206.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
