Description

Technical Field

[0001] The present invention relates to an offshore buoy platform, in particular to a projection type omnidirectional anti-rolling and stability-enhancing self-righting ocean platform. Background Art

[0002] When conducting offshore exploration or operation support, it is often necessary to deploy sensing devices such as sensors or other materials on the sea surface. In order to protect vulnerable sensors and facilitate fixed-point delivery, sensors are often placed in a platform and then dropped into the sea. Therefore, a projection type platform carrying sensors can achieve long-distance and rapid fixed-point delivery. This platform is also called a buoy, or an offshore buoy platform. Existing platforms generally include disk-shaped, cylindrical, spherical, ship-shaped buoys, etc. The vibration during the projection process and the waves on the sea surface have a great impact on high-precision sensing devices such as sensors. There are many kinds of harsh weather conditions at sea. When in harsh weather, the wind and waves on the sea are large. When the platform is greatly swayed or even overturned by the action of the waves, it will seriously affect the stability of various devices on the buoy, causing the platform to be carried away by the waves or even sink, resulting in the loss of sensors, high delivery costs, and high costs for offshore exploration and operation support. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to reduce the sway of the platform and improve the anti-wind and wave stability of the platform.

[0004] To solve the above technical problem, the present invention provides a projection type omnidirectional anti-rolling and stability-enhancing self-righting ocean platform, which includes: a first cone and a second cone connected as a whole, the bottom of the first cone is connected to the top of the second cone and has the same outer diameter, the top of the first cone is smaller than the bottom of the first cone, the top of the second cone is smaller than the bottom, the height of the first cone is smaller than the height of the second cone, a first compartment located in the second cone, an anti-rolling water tank placed in the first compartment, and a second compartment located on one longitudinal side of the first compartment, serving as a load compartment for placing sensors. When dropped into the water, the first cone is located below the second cone, and the first compartment is generally at the waterline position of the platform.

[0005] Preferably, in the projection type omnidirectional anti-rolling and stability-enhancing self-righting ocean platform, the anti-rolling water tank is formed by stacking and combining a plurality of water tank units. Each water tank unit includes a pair of liquid storage chambers and a connecting part. The liquid storage chamber has an opening for pouring liquid. The connecting part includes a channel communicating with the opening, and the opening and the channel are closed after pouring the liquid.

[0006] Preferably, in the projection type omnidirectional anti-rolling, stability increasing and self-righting ocean platform, the cross-sectional shape of the liquid storage chamber of the water tank unit is arc-shaped. After all the water tank units are combined, an anti-rolling water tank with a central angle of 360° and an overall cylindrical shape is obtained. The inner wall of the first chamber for placing the anti-rolling water tank matches the anti-rolling water tank.

[0007] Preferably, in the projection type omnidirectional anti-rolling, stability increasing and self-righting ocean platform, there are 3 water tank units, and the central angle corresponding to each arc is 60°.

[0008] Preferably, in the projection type omnidirectional anti-rolling, stability increasing and self-righting ocean platform, there are 4 water tank units, and the central angle corresponding to each arc is 45°.

[0009] Preferably, in the projection type omnidirectional anti-rolling, stability increasing and self-righting ocean platform, when placed in water, the second chamber is located above the first chamber.

[0010] Beneficial effects

[0011] The ocean platform of the present invention adopts a double-cone warhead, which can not only project the platform to the designated sea area more accurately, accelerating the speed and accuracy of offshore detection or support operations, but also has the characteristic of self-righting and can quickly right the platform to enter the working state.

[0012] The present invention also improves the shortcoming that an ordinary water tank can only provide anti-rolling effect in a certain direction. By stacking and splicing a plurality of water tank units with arc-shaped structures, a cylindrical anti-rolling water tank is formed, which can provide anti-rolling effects in all directions.

[0013] The proposed structural design of the cylindrical anti-rolling water tank of the present invention does not require high-quality materials, has a low cost of the structure, is easy to produce, and does not require additional energy consumption, and can be used on a large scale.

[0021] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0022] As Figure 1 shown, the present invention is a projection-type omnidirectional anti-rolling and self-righting ocean platform, which can also be called a buoy. It is integrally composed of a first cone 1 and a second cone 2 connected together. The bottom of the first cone 1 is connected to the top of the second cone 2 and their outer diameters are equal. The top of the first cone 1 is smaller than the bottom of the first cone, and the top of the second cone 2 is smaller than the bottom. The height of the first cone 1 is smaller than the height of the second cone 2. Therefore, overall, the volume of the second cone 2 is larger than the volume of the first cone 1. When placed in water, the first cone 1 is located below the second cone 2.

[0023] As Figure 2 shown, a first compartment 3 and a second compartment 5 are formed in the second cone 2. The first compartment 3 is generally at the middle position of the overall height of the ocean platform (that is, the sum of the heights of the first cone and the second cone). This position is close to the sea level when the ocean platform is put into the sea, that is, the first compartment 3 is generally at the waterline position of this ocean platform.

[0024] The second compartment 5 is a load compartment for placing devices such as sensors and is located on the longitudinal side of the first compartment. In this embodiment, the second compartment 5 is located above the first compartment 3. However, the present invention is not limited thereto. In other embodiments, the second compartment 5 may also be located below the first compartment 3.

[0025] Refer to Figures 3 - 6 , an anti-rolling water tank 4 is placed in the first compartment 3. The anti-rolling water tank 4 is formed by stacking and combining a plurality of water tank units 40. Each water tank unit 40 includes a pair of liquid storage chambers 41 and a connecting portion 42. The liquid storage chamber 41 has an opening 43 for pouring liquid. The connecting portion 42 includes a channel 44 communicating with the opening 43. The opening 43 and the channel 44 are closed after pouring the liquid. The poured liquid is water in this embodiment, and it can also be other liquids.

[0026] The cross-sectional shape of the liquid storage chamber 41 of the water tank unit 40 is arc-shaped. After all the water tank units 40 are combined, a roll damping water tank 4 with a central angle of 360° and an overall cylindrical shape is obtained. The inner wall of the first chamber 3 where the roll damping water tank 4 is placed is also cylindrical, matching the outer shape of the water tank unit 40. In this embodiment, the number of water tank units 40 is 3, and the central angle corresponding to each arc is 60°. After stacking and combining 3 water tank units together, the complete roll damping water tank 4 is formed. However, the present invention does not limit the number of water tank units. In other embodiments, the number of water tank units 40 can be 4, and the central angle corresponding to each arc is 45°. The number of water tank units 40 can also be 6, and the central angle corresponding to each arc is 30°, and so on. Since a roll damping water tank can only reduce roll in one direction and 360 degrees of roll reduction is required, the roll damping water tank of the present invention adopts a splicing method to achieve omnidirectional roll reduction.

[0027] Due to the positional relationship of the connecting portion 42, when stacking multiple water tank units 40, there will be a height difference in the liquid storage chambers 41 of different water tank units 40, causing the top and bottom surfaces of each water tank unit 40 not to be in the same plane. Solid materials can be filled in the missing parts with height differences between adjacent water tank units to ensure that the top and bottom surfaces of the roll damping water tank 4 are in the same plane for placement in the first chamber 3. Alternatively, the connecting portions 42 of different water tank units 40 are set at different heights so that they will not interfere with each other during stacking, thereby ensuring that the top and bottom surfaces of the roll damping water tank 4 are in the same plane.

[0028] The functional schematic diagram of the offshore platform of the present invention is as Figure 7 shown. When receiving the offshore operation requirements, the offshore platform is projected. Due to the structure and center of gravity relationship of the double cone, the offshore platform will self-right to the vertical state, with the first cone 1 below the sea surface and the second cone 2 above the sea surface. The first chamber 3 provided with the roll damping water tank 4 is at the sea level position. When the offshore platform fluctuates with the waves, due to the setting of multiple roll damping water tanks 4, the waves are offset in the opposite direction, thereby achieving the effect of reducing the swing amplitude and enabling the offshore platform to quickly reach a stable working state.

[0029] 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.
