Description

Technical Field

[0001] This invention relates to the field of anti-collision device technology, and more particularly to an anti-collision connector, a monopile foundation, and an offshore wind farm. Background Technology

[0002] Offshore monopile foundations are frequently subjected to impact forces from ships, ice floes, or other floating objects during use. Therefore, protective devices are usually installed on offshore monopile foundations to provide a buffering effect.

[0003] Existing monopile foundation protection devices are usually complex in structure and difficult to assemble at sea, especially in extreme sea conditions, which increases the difficulty of assembly and reduces the efficiency of assembly.

[0004] Therefore, how to improve the assembly efficiency of monopile foundation protection devices is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an anti-collision connector to improve assembly efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-collision connector, comprising:

[0008] A connector for connecting to the first body, wherein the connector has a buffer cavity inside;

[0009] An energy storage component, comprising an elastic buffer and a force transmission block, wherein the elastic buffer is disposed within a buffer cavity, a first end of the force transmission block is connected to the elastic buffer, and a second end of the force transmission block protrudes from the buffer cavity; and

[0010] A modular assembly assembly includes a fixed base, a modular base, and a pin. The fixed base is used to connect to a second body. One of the fixed base and the modular base has a protrusion, and the other has a recess. The protrusion and the recess can cooperate with each other. Both the protrusion and the recess have a connecting hole through which the pin can pass. After the fixed base and the modular base are connected, they form a locking cavity that can lock the second end of the force transmission block.

[0011] A buffer gap is reserved between the connector and the fixed base.

[0012] Preferably, in the above-mentioned anti-collision connector, the force transmission block is in the shape of a frustum cone, and the first end of the force transmission block is the small diameter end, and the second end of the force transmission block is the large diameter end.

[0013] Preferably, in the above-mentioned anti-collision connector, the elastic buffer includes a first spring and a second spring, the first spring connecting the bottom of the force transmission block and the bottom of the buffer cavity, and the second spring connecting the conical wall of the force transmission block and the inner wall of the buffer cavity.

[0014] Preferably, in the above-mentioned anti-collision connector, there are multiple second springs, and the multiple second springs are evenly distributed along the outer circumference of the force transmission block.

[0015] Preferably, in the above-mentioned anti-collision connector, the buffer cavity is provided with a first guide structure for guiding the extension and retraction of the first spring and a second guide structure for guiding the extension and retraction of the second spring.

[0016] Preferably, in the above-mentioned anti-collision connector, the first guide structure is a first guide groove, and the second guide structure is a second guide groove.

[0017] Preferably, in the above-mentioned anti-collision connector, the force transmission block is provided with a first axial positioning structure, and at least one of the second body, the fixed base and the splicing base is provided with a second axial positioning structure that can cooperate with the first axial positioning structure.

[0018] A monopile foundation includes a monopile body, an anti-collision member located outside the monopile body, and an anti-collision connector as described above. The monopile body is connected to the connecting body of the anti-collision connector, and the anti-collision member is connected to the fixed base of the anti-collision connector.

[0019] Preferably, in the above-mentioned monopile foundation, the outer side of the anti-collision component and the outer wall of the monopile body are both coated with an anti-corrosion coating.

[0020] An offshore wind farm includes a collision-resistant connector as described above.

[0021] When using the anti-collision connector provided by this invention, the connector body is connected to the first body, and the fixed base of the splicing assembly is connected to the second body. Since the connector body has an internal buffer cavity with an elastic buffer inside, the first end of the force transmission block is connected to the elastic buffer, and the second end of the force transmission block protrudes from the buffer cavity. Furthermore, the fixed base and the splicing base form a locking cavity that can lock the second end of the force transmission block. Therefore, the second end of the force transmission block can be locked together by the splicing base and the fixed base, allowing for rapid connection between the splicing assembly and the energy storage assembly. Since the first body is pre-connected to the connector body, and the second body is pre-connected to the fixed base, when connecting the first body and the second body using this anti-collision connector, it is only necessary to place the force transmission block between the fixed base and the splicing base. The fixed base and the splicing base are joined together by recesses and protrusions. A pin is passed through the connecting holes in the protrusions and recesses to quickly engage the second end of the force transmission block, thus enabling rapid connection of the first and second bodies via this anti-collision connector. Because a buffer gap is reserved between the connector and the fixed base, after the first and second bodies are connected via the anti-collision connector, when an external force impacts the second body, the force transmission block moves towards the side closer to the connector along with the second body. The buffer gap provides travel space for the force transmission block's movement. The force transmission block transmits the impact force to the elastic buffer, which stores the energy of the impact force, reducing rigid collisions between the first and second bodies and extending their service life. After the impact force disappears, the energy stored in the elastic buffer is released, pushing the force transmission block back to its original position. Therefore, the anti-collision connector provided by this invention not only buffers impact forces but also enables rapid assembly through splicing assembly components, reducing assembly difficulty and improving assembly efficiency.

Detailed Implementation

[0028] In view of this, the core of the present invention is to provide an anti-collision connector to improve assembly efficiency.

[0029] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention discloses an anti-collision connector, including a connector body 100, an energy storage component 200, and a splicing assembly component 300.

[0031] The connector 100 is used to connect with the first body 400, and the connector 100 has a buffer cavity inside. The energy storage component 200 includes an elastic buffer 201 and a force transmission block 202. The elastic buffer 201 is disposed in the buffer cavity, the first end of the force transmission block 202 is connected to the elastic buffer 201, and the second end of the force transmission block 202 is exposed in the buffer cavity. The splicing assembly component 300 includes a fixed base 301, a splicing base 302, and a pin 303. The fixed base 301 is used to connect with the second body 500. One of the fixed base 301 and the splicing base 302 has a protrusion, and the other has a recess. The protrusion and the recess can cooperate with each other. Both the protrusion and the recess have a connecting hole through which the pin 303 can pass. After the fixed base 301 and the splicing base 302 are connected, a locking cavity is formed that can lock the second end of the force transmission block 202. In addition, a buffer gap is reserved between the connector 100 and the fixed base 301.

[0032] When using the anti-collision connector provided by this invention, the connector 100 is connected to the first body 400, and the fixed base 301 of the splicing assembly 300 is connected to the second body 500. Since the connector 100 has a buffer cavity inside, the elastic buffer 201 is disposed in the buffer cavity. The first end of the force transmission block 202 is connected to the elastic buffer 201, and the second end of the force transmission block 202 protrudes from the buffer cavity. After the fixed base 301 is connected to the splicing base 302, a second force transmission block 202 can be engaged. The second end of the force transmission block 202 can be snapped together by the splicing base 302 and the fixed base 301, allowing the splicing assembly 300 to be quickly connected to the energy storage assembly 200. Since the first body 400 is pre-connected to the connector 100 and the second body 500 is pre-connected to the fixed base 301, when connecting the first body 400 and the second body 500 through this anti-collision connector, it is only necessary to place the force transmission block 202 on the fixed base 301 and the splicing base 301. Between 2, the fixed base 301 and the splicing base 302 are spliced ​​together through the concave and convex parts. By passing the pin 303 through the connecting holes of the convex and concave parts, the second end of the force transmission block 202 can be quickly engaged, thereby quickly connecting the first body 400 and the second body 500 through the anti-collision connector. Since a buffer gap is reserved between the connector 100 and the fixed base 301, after the first body 400 and the second body 500 are connected through the anti-collision connector, when an external force impacts the second body 500, The force transmission block 202 moves with the second body 500 towards the side closer to the connector 100. The buffer gap provides travel space for the movement of the force transmission block 202. The force transmission block 202 transmits the impact force to the elastic buffer 201, which stores the energy of the impact force, reducing the rigid collision between the first body 400 and the second body 500, and extending the service life of the first body 400 and the second body 500. After the impact force disappears, the energy stored in the elastic buffer 201 is released, pushing the force transmission block 202 to reset. Therefore, the anti-collision connector provided by this invention not only achieves the function of buffering impact force, but also enables rapid assembly through the splicing assembly component 300, reducing assembly difficulty and improving assembly efficiency.

[0033] It should be noted that the above-mentioned force transmission block 202 can be of the shape of a frustum, cylinder, or cuboid, etc. Any type that can meet the usage requirements is within the protection scope of this invention; Optionally, the force transmission block 202 provided in the embodiment of this invention is of the shape of a frustum, and the first end of the force transmission block 202 is the small diameter end, and the second end of the force transmission block 202 is the large diameter end.

[0034] In addition, the pin 303 can be placed vertically or tilted to the vertical direction, so that the pin 303 is stably installed in the connecting hole of the protrusion and the concave part under its own weight. Alternatively, the pin 303 can be placed horizontally, and a fastener can be provided at the end of the pin 303 to stably install the pin 303 in the connecting hole of the protrusion and the concave part. Any setting method that can meet the usage requirements is within the protection scope of this invention.

[0035] Furthermore, the elastic buffer 201 can be a spring, a rubber block, or a high-resilience foam plastic filled in the buffer cavity, etc. Any type that can meet the usage requirements is within the protection scope of this invention; optionally, the elastic buffer 201 provided in the embodiment of this invention is a spring.

[0036] Specifically, the elastic buffer 201 includes a first spring 2011 and a second spring 2012. The first spring 2011 connects the bottom of the force transmission block 202 and the bottom of the buffer cavity, and the second spring 2012 connects the conical wall of the force transmission block 202 and the inner wall of the buffer cavity, so that the first spring 2011 and the second spring 2012 can play a buffering role and improve the buffering capacity of the anti-collision connector.

[0037] Furthermore, there are multiple second springs 2012, and these multiple second springs 2012 are evenly distributed along the outer circumference of the force transmission block 202 to improve the stability of the anti-collision connector.

[0038] like Figure 4 As shown, after the second body 500 is impacted by an external force, the large-diameter end of the truncated cone-shaped force transmission block 202 is subjected to the impact force. The impact force pushes the force transmission block 202 to compress the first spring 2011 and the second spring 2012. After the first spring 2011 and the second spring 2012 are compressed, they respectively generate a first elastic force perpendicular to the bottom of the force transmission block 202 and a second elastic force perpendicular to the side wall of the force transmission block 202. The resultant force of the first elastic force of the first spring 2011 and the second elastic force of the multiple second springs 2012 is balanced with the impact force. After the impact force disappears, the first elastic force and the second elastic force push the truncated cone-shaped force transmission block 202 to reset.

[0039] In one specific embodiment of the present invention, there are four second springs 2012, and adjacent second springs 2012 are spaced 90° apart to balance the forces on the frustum-shaped force transmission block 202. Let α be the angle between the generatrix of the cone and the height line of the force transmission block 202. Then, when the impact force is balanced by the resultant force of the first elastic force and the second elastic force, the following conditions are met:

[0040] F 撞击 =F 弹1 +4F 弹2 cosα

[0041] Among them, F撞击 The impact force transmitted by force transmission block 202, F 弹1 F is the first elastic force of the first spring. 弹2 The second elastic force of the second spring, after the impact force disappears, the resultant force formed by the first elastic force and the second elastic force pushes the force transmission block 202 to reset, thereby improving the reset capability of the anti-collision connector.

[0042] It should be understood that the present invention does not limit the specific value of the included angle α. Any included angle value that can meet the usage requirements is within the protection scope of the present invention.

[0043] In addition, the buffer cavity provided by the present invention is provided with a first guide structure and a second guide structure, so as to guide the extension and retraction of the first spring 2011 through the first guide structure and guide the extension and retraction of the second spring 2012 through the second guide structure, so as to prevent the first spring 2011 and the second spring 2012 from being tilted during the buffering process, which would affect the normal use of the anti-collision connector.

[0044] The first and second guiding structures described above can be guide grooves, guide rods, or guide rail slider combinations, etc. Any structure that can achieve a guiding function is within the scope of protection of this invention. Optionally, the first guiding structure provided in the embodiments of this invention is a first guide groove, and the second guiding structure is a second guide groove.

[0045] Furthermore, the lengths of the first and second guide grooves mentioned above should not be too long to prevent interference between the first and second guide grooves and the force transmission block 202. That is, the force transmission block 202 will have a rigid collision with the first and second guide grooves during the movement, which will affect the buffering effect of the anti-collision connector.

[0046] Furthermore, the force transmission block 202 is provided with a first axial positioning structure, and at least one of the second body 500, the fixed base 301 and the splicing base 302 is provided with a second axial positioning structure that can cooperate with the first axial positioning structure. The cooperation of the first axial positioning structure and the second axial positioning structure restricts the relative position of the force transmission block 202, the splicing base 302 and the fixed base 301, and prevents the force transmission block 202 from axially moving in the snap-fit ​​cavity, which would affect the normal use of the anti-collision connector.

[0047] The first axial positioning structure described above can directly utilize the end face of the force transmission block 202, or a positioning shoulder can be set at the end of the force transmission block 202 as the first axial positioning structure, or a positioning protrusion or positioning groove can be set on the outer circumferential surface of the force transmission block 202 as the first axial positioning structure; the second axial positioning structure can directly utilize the end face on the second body 500, or a positioning groove or positioning boss can be set in at least one of the fixed base 301 and the splicing base 302 as the second axial positioning structure. Any structure type that can meet the axial positioning requirements is within the protection scope of this invention.

[0048] In addition, the present invention also discloses a monopile foundation, including a monopile body, an anti-collision member located outside the monopile body, and an anti-collision connector as described above. The monopile body is connected to the connector body 100 of the anti-collision connector, and the anti-collision member is connected to the fixing base 301 of the anti-collision connector, so as to connect the monopile body and the anti-collision member through the anti-collision connector. When the anti-collision member is impacted, the anti-collision connector plays a buffering role.

[0049] The outer side of the aforementioned anti-collision components and the outer wall of the monopile body are coated with an anti-corrosion coating to reduce corrosion from seawater and marine salt spray and extend their service life.

[0050] In addition, the present invention also discloses an offshore wind farm, including the anti-collision connector as described above, thus taking into account all the technical effects of the aforementioned anti-collision connector, which will not be elaborated upon here.

[0051] It should be understood that the anti-collision connector provided by the present invention can be used, but is not limited to, offshore wind farms, and can also be used in fields such as automotive anti-collision or building anti-collision. Therefore, the present invention does not specifically limit the application scope of the anti-collision connector.
