Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to an anti-collision device for offshore wind power and a method of using the device. Background Art

[0002] With the increasing shortage of energy, offshore wind power has developed rapidly as a clean and renewable energy source. As the support system of offshore wind turbines, wind turbine foundations play a very important role in ensuring the overall safety of offshore wind power, and the protection of wind turbine foundations is also particularly important. Although the probability of a ship colliding with a wind turbine foundation is low, the losses caused by such an accident are unimaginable. At the least, the foundation and hull will be damaged, and at the worst, the foundation will collapse, the wind turbine will be damaged, the hull will be structurally damaged, and even casualties will occur, resulting in huge direct economic losses. The indirect losses after the accident are also difficult to estimate. After the foundation is damaged, offshore maintenance operations are difficult and risky, and it also has an adverse effect on wind turbine power generation, reducing power generation.

[0003] In the existing offshore wind power anti-collision device, such as an offshore wind power foundation anti-collision system with application number CN201620857847.6, its technical solution is: including a circular foundation located in the center, at least one rotating anti-collision device arranged along the axial direction is arranged on the periphery of the foundation, the rotating anti-collision device includes a rotating system that can rotate relative to the foundation, and an anti-collision layer is arranged on the periphery of the rotating system. In the utility model, when a ship hits the foundation, the anti-collision layer will rotate around the foundation through the rotating system, instantly changing the collision direction and the displacement direction of the hull, so that the ship slides along the outside of the anti-collision device to avoid a head-on collision, while reducing the energy acting on the foundation, and the anti-collision layer and the buffer layer consume part of the impact energy, thereby reducing the impact force of the ship and reducing the degree of damage to the foundation and the ship. However, the effect of the existing offshore wind power anti-collision device on ship collision is weak, and the anti-collision device itself lacks protection, so there will be certain damage, which affects the use of later anti-collision measures. At the same time, the lack of an alarm system makes it impossible to notify the outer edge of emergency maintenance in time.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In response to the above problems, an innovative design was carried out based on the original offshore wind power anti-collision device. Summary of the invention

[0006] The object of the present invention is to provide an anti-collision device for offshore wind power and a method of use, so as to solve the problems mentioned in the above background technology that the anti-collision system itself lacks anti-collision protection and has a weak buffering effect when impacted.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0009] Preferably, the interior of the anti-collision cover is filled with a plurality of air bags, and the protective cover is in the shape of a tire and surrounds the outside of the anti-collision cover, and the protective cover is made of rubber.

[0010] By adopting the above technical solution, the back of the anti-collision cover is filled with air bags to ensure its anti-collision elasticity underwater, and the protective cover provides anti-collision protection for the outside of the anti-collision cover, thereby ensuring the safety and stability of the foundation pile.

[0011] Preferably, the upper edge of the anti-collision cover is inclined, and a touch switch is installed on the upper edge of the anti-collision cover, the touch switch circuit is connected to the alarm device, and the impact block hits the touch switch to activate the alarm device.

[0012] By adopting the above technical solution, when the impact block is impacted from the outside and moves inward to contact the touch switch, the line connection activates the alarm device, and timely support can be obtained, thereby improving the safety of offshore wind power operation and maintenance.

[0013] Preferably, a limiting groove is provided in the middle of the impact block, and the limiting groove is V-shaped, a limiting shaft is arranged inside the limiting groove, and a moving block is connected and installed on the rear side of the limiting shaft.

[0014] By adopting the above technical solution, when the outer side of the impact block is hit, it slides inwardly when connected to the inside of the anti-collision block, and the limiting shaft moves up and down according to the shape of the limiting groove, thereby driving the moving block to move up and down, providing a steering effect for the direction of the impact force, thereby reducing the potential energy of the force.

[0015] Preferably, a first spring is connected and installed above the moving block, and the upper end of the first spring is connected to the bottom of the fixing member.

[0016] By adopting the above technical solution, when the moving block moves up and down, the elastic potential energy of the first spring is used to reduce the up and down movement of the moving block, convert the impact force in the horizontal direction into the vertical direction and reduce the potential energy.

[0017] Preferably, a support frame is connected and installed below the anti-collision block, and a sliding rod is connected and installed on the left side of the support frame, a second spring is installed on the outside of the sliding rod, and the outer end of the second spring is connected to the support frame, and the inner end of the second spring is connected to the outside of the anti-collision sleeve.

[0024] By adopting the above technical solution, when the buffer pulley slides inside the buffer slide rail, the buffer slide rail terminal is in an arc shape, which drives the buffer pulley to move in the reverse direction due to inertia, thereby performing a secondary buffering effect on the impact force.

[0025] Preferably, the method for using the anti-collision device for offshore wind power comprises the following steps:

[0026] Step 1: When the outer side of the protective cover is first hit, the sliding rod is driven to shrink toward the inside of the anti-collision cover, and the second spring is compressed to drive the impact block to move toward the foundation pile;

[0027] Step 2: When the impact block is impacted from the outside and moves inward to contact the touch switch, the line connection turns on the alarm device;

[0028] Step three, when the outer side of the impact block is impacted, when it is slidably connected to the inside of the anti-collision block and moves inward, the limiting shaft moves up and down according to the shape of the limiting groove, thereby driving the moving block to move up and down, providing a steering effect for the direction of the impact force, and reducing the up and down movement of the moving block through the elastic potential energy of the first spring, converting the horizontal impact force into the vertical direction and reducing the potential energy;

[0029] Step four, when the support frame moves inward, it drives the telescopic rod to rotate, drives the support rod to rotate, and then drives the buffer pulley from the horizontal direction to the vertical direction to contact the buffer slide rail. When the buffer pulley slides inside the buffer slide rail, the buffer slide rail terminal is in an arc shape, which drives the buffer pulley to move in the opposite direction due to inertia, thereby performing a secondary buffering effect on the impact force.

[0030] By adopting the above technical solution, the anti-collision sleeve itself is protected, and the direction of the impact force is converted by the movement of the impact block. While buffering is performed by the first spring, the inertial movement of the buffer pulley is driven in linkage to form a secondary buffer to improve the anti-collision ability, thereby improving the anti-collision ability of the foundation pile.

[0048] The anti-collision cover 2 is filled with a number of air bags 3, and the protective cover 4 is in the shape of a tire and surrounds the outside of the anti-collision cover 2, and the protective cover 4 is made of rubber. The upper edge of the anti-collision cover 2 is inclined, and a touch switch 6 is installed on the upper edge of the anti-collision cover 2. The touch switch 6 is connected to the alarm device 7, and the impact block 5 hits the touch switch 6 to turn on the alarm device 7. The air bags 3 filled on the back of the anti-collision cover 2 are used to ensure its anti-collision elasticity underwater, and the protective cover 4 provides anti-collision protection for the outside of the anti-collision cover 2, thereby ensuring the safety and stability of the foundation pile 1. When the impact block 5 is hit by the outside and moves inward to contact the touch switch 6, the line connection turns on the alarm device 7, and timely support can be obtained, thereby improving the safety of offshore wind power operation and maintenance.

[0049] A limiting groove 8 is provided in the middle of the impact block 5, and the limiting groove 8 is V-shaped. A limiting shaft 10 is arranged inside the limiting groove 8, and a moving block 11 is connected and installed on the rear side of the limiting shaft 10. A first spring 12 is connected and installed above the moving block 11, and the upper end of the first spring 12 is connected to the bottom of the fixing member 13. When the outer side of the impact block 5 is impacted, it slides and moves inward inside the anti-collision block 9, and the limiting shaft 10 moves up and down according to the shape of the limiting groove 8, thereby driving the moving block 11 to move up and down, providing a steering effect for the direction of the impact force, thereby reducing the potential energy of the force. When the moving block 11 moves up and down, the elastic potential energy of the first spring 12 is used to reduce the up and down movement of the moving block 11, converting the impact force in the horizontal direction into the vertical direction and reducing the potential energy.

[0050] A support frame 16 is connected and installed below the anti-collision block 9, and a slide bar 14 is connected and installed on the left side of the support frame 16. A second spring 15 is installed on the outside of the slide bar 14, and the outer end of the second spring 15 is connected to the support frame 16, and the inner end of the second spring 15 is connected to the outside of the anti-collision sleeve 2.

When the telescopic rod 17 rotates, it drives the support rod 19 to rotate, thereby driving the buffer pulley 20 to change from the horizontal direction to the vertical direction to contact the buffer rail 21. When the buffer pulley 20 slides inside the buffer rail 21, the buffer pulley 20 is driven by inertia to move in the reverse direction due to the arc shape of the terminal end of the buffer rail 21, and the impact force is buffered twice.

[0051] The method for using the anti-collision device for offshore wind power comprises the following steps:

[0052] Step 1: When the outer side of the protective sleeve 4 is first hit, the sliding rod 14 is driven to shrink toward the inside of the anti-collision sleeve 2, and the second spring 15 is compressed, driving the impact block 5 to move toward the pile 1;

[0053] Step 2: When the impact block 5 is impacted from the outside and moves inward to contact the touch switch 6, the line connection turns on the alarm device 7;

[0054] Step three, when the outer side of the impact block 5 is impacted, it is slidably connected to the inside of the anti-collision block 9 and moves inward, and the limiting shaft 10 moves up and down according to the shape of the limiting groove 8, thereby driving the moving block 11 to move up and down, providing a steering effect for the direction of the impact force, and reducing the up and down movement of the moving block 11 through the elastic potential energy of the first spring 12, converting the horizontal impact force into the vertical direction and reducing the potential energy;

[0055] Step 4: When the support frame 16 moves inward, it drives the telescopic rod 17 to rotate, drives the support rod 19 to rotate, and then drives the buffer pulley 20 to change from the horizontal direction to the vertical direction to contact the buffer slide rail 21. When the buffer pulley 20 slides inside the buffer slide rail 21, the buffer slide rail 21 terminal is in an arc shape, which drives the buffer pulley 20 to move in the opposite direction by inertia, and performs a secondary buffering effect on the impact force. While the anti-collision sleeve 2 itself is protected, the direction of the impact force is converted by the movement of the impact block 5. While the first spring 12 is used for buffering, the inertial movement of the buffer pulley 20 is driven by linkage to form a secondary buffer to improve the anti-collision ability, and improve the anti-collision ability of the foundation pile 1.
