Description

Technical Field

[0001] The present invention belongs to the technical field of offshore wind power construction, and in particular relates to an offshore wind power construction platform. Background Art

[0002] During offshore wind power construction, large installation ships need to be docked in the corresponding area to install or repair wind turbines. The cost of large installation ships is high, resulting in high installation costs for offshore wind power. The prior art application number CN202011166116.4 provides an offshore wind power construction platform, including a buoy base and a platform device, the platform device is detachably mounted on the top surface of the buoy base, and the platform device is foldable. Multiple offshore wind power construction platforms can be deployed at sea at the same time to perform construction operations on multiple wind turbines at the same time, thereby improving the construction progress of offshore wind power while ensuring low costs. Transport ships are only used for the transportation, deployment and recovery of offshore platforms. There is no need to dock at workstations for a long time. The above operations can be completed using a small number of transport ships, thereby reducing the requirements for the number of transport ships and the length of time the transport ships are docked at sea, which greatly reduces the installation and maintenance costs of wind turbines.

[0003] However, this technology does not take into account that under severe conditions such as frequent wind and waves at sea, the size of a single offshore wind power construction platform in the above technical solution is small and its ability to resist risks is weak. Therefore, the offshore wind power construction platform lacks protection. On the one hand, it is easy to capsize or other dangers causing losses, and on the other hand, it affects the progress of the offshore wind power installation cycle. Summary of the invention

[0004] The purpose of the present invention is to provide an offshore wind power construction platform to solve the problem that the offshore wind power construction platform lacks protection under severe conditions such as frequent wind and waves at sea, which on the one hand is prone to capsizing or other dangers leading to losses, and on the other hand affects the progress of the offshore wind power installation cycle.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An offshore wind power construction platform comprises a buoy base and a detachable mounting platform, wherein the mounting platform comprises support legs, and the support legs are mounted on the buoy base through connectors; a balancing mechanism is also mounted on the bottom of the buoy base, and connecting mechanisms are mounted on both sides of the buoy base;

[0007] The balancing mechanism comprises a floating ring, which is hollow inside and fixed around the bottom of the buoy base. The floating ring is inflated by an air pump installed on the buoy base, and a deflation valve is provided on the top of the floating ring.

[0008] The balancing mechanism also includes a middle enclosure, which is fixed to the middle area of ​​the bottom wall of the buoy base. A plurality of float bags are arranged on the inner circumference of the middle enclosure, and the float bags are respectively connected to the air pump through an intake pipe equipped with a one-way intake valve.

[0009] Preferably, the connecting member includes a locking pin and a support plate, the support plate is fixed on the buoy base, and the locking pin locks the support leg on the support plate; there are at least two support legs, and the tops of the support legs are hinged to the truss.

[0010] Preferably, the float bladder is cylindrical.

[0011] Preferably, the connection mechanism comprises two connection frames with pin holes, one of which is hinged with an L-shaped bracket with a pin hole at the end, and the two connection frames are respectively placed on both sides of the buoy base, and when two adjacent connection frames are aligned, a pin shaft is inserted to form a movable connection, and multiple connection frames are connected end to end through the pin shaft and the pin hole to form various shapes;

[0012] Preferably, the floating ring is respectively arranged in the shape of a groove and an arc-shaped protrusion at the position corresponding to the connecting frame, and the shape of the groove matches the shape of the arc-shaped protrusion.

[0013] Preferably, a chain is ball-hinged at the center of the bottom of the buoy base, and a balancing ball is suspended at the bottom end of the chain.

[0014] Preferably, a spring is welded to the outside of the balancing ball, and a ball segment is welded to the free end of the spring.

[0015] Preferably, pile holes are provided on both sides of the buoy base, and a guide mechanism is installed around the pile holes of the buoy base;

[0016] The guide mechanism includes a plurality of columns, which are fixed on a buoy base and distributed along the circumference of the pile hole. A telescopic column is fixedly mounted on the column, and a ball is connected to the telescopic end of each telescopic column. By changing the telescopic length of the telescopic column, it is suitable for installation of single pile foundations of different sizes.

[0017] Preferably, there are at least two pile holes.

[0018] Preferably, a locking seat is installed on the side of the buoy base. When the upper and lower buoy bases are stacked together, the locking eyes on the locking seat are aligned and fixed with a steel wire or a safety buckle.

[0019] Technical effects and advantages of the present invention: Compared with the prior art, the offshore wind power construction platform proposed by the present invention has the following advantages:

[0020] 1. The present invention drops the buoy base to the work station by means of a transport ship, and then locks the supporting legs and the truss on the buoy base by means of locking pins. After being fixed, an installation platform is formed and installed on the buoy base. The installation platform is used to carry the workers for operation. When encountering severe weather such as frequent wind and waves, the balancing mechanism is first started, and the air pump in the balancing mechanism is started to inflate the float ring. After the float ring is inflated, it expands rapidly and forms a circle around the buoy base, thereby increasing the contact area between the buoy base and the seawater, making the buoy base more balanced and less prone to capsizing, thereby enhancing the safety of the offshore construction platform.

[0021] 2. The present invention directly connects multiple buoy bases, i.e., offshore wind power construction platforms, together through a transport ship, and connects them end to end through a connecting mechanism. Under the positioning of a balancing mechanism, the nearby offshore construction platforms can be dragged together to form a stable whole. Depending on the number of buoy bases, a triangular or diamond structure can be formed. Multiple buoy bases form a larger offshore construction platform, which is more stable at sea, less prone to capsizing, and has enhanced wind and wave resistance. Therefore, in periods of frequent wind and waves, the present invention can also carry out offshore wind power installation work, which greatly improves the adaptability of the present invention and ensures the offshore wind power installation period.

[0022] 3. The present invention uses a suspended balancer. When the buoy base is moved or swayed by the impact of wind and waves, the balancing ball connected by the free ball can always keep the center of gravity vertical to the horizontal plane, providing a downward pulling force on the buoy base, thereby increasing the difficulty of the buoy base breaking away from the sea surface, that is, capsizing. The connection mechanism and the balancing mechanism make the offshore construction platform more stable and safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides Figure 1-6 An offshore wind power construction platform is shown.

[0031] Embodiment 1:

[0032] It includes a buoy base 1 and a detachable mounting platform, the mounting platform includes a supporting leg 2, the supporting leg 2 is detachably fixed to the buoy base 1 through a connecting member 4; a balancing mechanism 3 is also installed at the bottom of the buoy base 1, connecting mechanisms 5 are installed on both sides of the buoy base 1, the connecting member 4 includes a locking pin 41 and a supporting plate 42, the supporting plate 42 is fixed on the buoy base 1, and the locking pin 41 locks the supporting leg 2 on the supporting plate 42; there are at least two supporting legs 2, and the tops of the supporting legs 2 are hinged to the truss 43; when encountering bad weather, the balance of the buoy base 1 is adjusted by the balancing mechanism 3 and positioning is provided for adjacent buoy bases 1 to be connected end to end through the connecting mechanism 5.

[0033] A locking seat 11 is installed on the side of the buoy base 1. When the upper and lower buoy bases 1 are stacked together, the locking eyes on the locking seat 11 are aligned and fixed with a steel wire or a safety buckle. The stacked buoy bases 1 are firm and not easy to loosen, thereby facilitating the transportation and stacking of the buoy bases 1.

[0034] Furthermore, the balancing mechanism 3 includes a float 31 , which is hollow inside and fixed around the bottom of the buoy base 1 . The float 31 is inflated by an air pump installed on the buoy base 1 , and a deflation valve is provided on the top of the float 31 .

[0035] Furthermore, the connection mechanism 5 includes two connection frames 52 with pin holes 51, one of the connection frames 52 is hinged with an L-shaped bracket, and the two connection frames 52 are respectively placed on both sides of the buoy base 1. When two adjacent connection frames 52 are aligned, a pin shaft 53 is inserted to form a movable connection. Multiple connection frames 52 are connected end to end through the pin shaft 53 and the pin hole 51 to form various shapes;

[0036] The floating ring 31 is respectively arranged in the shape of a groove 32 and an arc-shaped protrusion 33 at the position corresponding to the connecting frame 52 , and the shapes of the groove 32 and the arc-shaped protrusion 33 match each other.

[0037] When in use, the present invention puts the buoy base 1 to the work station through a transport ship, and then locks the support legs 2 and the truss 43 on the buoy base 1 through the locking pins 41. After being fixed, an installation platform is formed and installed on the buoy base 1. The installation platform is used to carry the staff to operate. When encountering severe weather such as frequent wind and waves, the balancing mechanism 3 is first started, and the air pump in the balancing mechanism 3 is started to inflate the floating ring 31. After the floating ring 31 is inflated, it expands rapidly and forms a ring around the buoy base 1, thereby increasing the contact area between the buoy base 1 and the seawater, so that the buoy base 1 is more balanced and not easy to capsize, thereby enhancing the safety of the offshore construction platform;

[0038] Due to the large number of wind and waves at sea, a single offshore construction platform in the prior art lacks necessary protective measures, so the safety of the offshore construction platform and the wind turbine assembly cannot be guaranteed. Therefore, the present invention directly connects multiple buoy bases 1, i.e., offshore wind power construction platforms, together through a transport ship, and connects them end to end through a connecting mechanism 5. Under the positioning of the balancing mechanism 3, the nearby offshore construction platforms can be dragged together to form a stable whole, thereby enhancing the stability of the offshore wind power platform and further improving the wind and wave resistance of the offshore wind power platform. At this time, the offshore wind power installation can still continue, providing conditions for shortening the offshore wind power installation period;

[0039] Specifically, with one of the buoy bases 1 placed at the installation station as the center, multiple buoy bases 1 are placed at one time, and then the connecting frame 52 is aligned with the operator on the buoy base 1. Since the bulging shapes of the float rings 31 after inflation are consistent, inserting the protruding part between two adjacent float rings 31 into the groove 32 indicates that the pin holes 51 on the connecting frame 52 have been aligned. At this time, it is only necessary to insert the pin shaft 53 into the pin hole 51 to complete the locking. Then, multiple buoy bases 1 are connected end to end in sequence. Depending on the number of buoy bases 1, polygonal or V-shaped shapes can be formed. Multiple buoy bases 1 form a larger offshore construction platform, which has stronger stability at sea, is not prone to capsizing, and has enhanced wind and wave resistance. Therefore, in periods of frequent wind and waves, the present invention can also carry out offshore wind power installation work, which greatly improves the adaptability of the present invention and ensures the offshore wind power installation period.

[0040] When encountering sudden strong winds and waves, the transport ship uses an anchor hook to fix on one of the buoy bases 1 and use it as the center, then uses an iron chain to connect the nearby buoy bases 1 in series in sequence away from the center, and then moves towards the center as much as possible to achieve the gathering of multiple buoy bases 1, i.e., offshore construction platforms. Multiple transport ships can form multiple gathering blocks by working synchronously, which increases the ability to resist strong winds and waves, and the reaction time is short. There is no need to disassemble or fold the offshore construction platform. The transport ship only needs to move back and forth to connect the buoy bases 1 in series with the iron chain. Comparatively speaking, the reaction time is short, the effect of gathering together to resist wind and waves is better, and the safety is further improved.

[0041] The balancing mechanism 3 also includes a middle enclosure 34, which is fixed to the middle area of ​​the bottom wall of the buoy base 1. A plurality of floating bags 35 are arranged on the inner circumference of the middle enclosure 34. The floating bags are cylindrical and are connected to the air pump through an air intake pipe equipped with a one-way air intake valve. The air pump can inflate the buoy base 1 when it is launched into the water, so that the plurality of floating bags 35 are filled and filled into the entire middle enclosure 34, and finally form a circular floating body, which increases the buoyancy of the buoy base 1 and improves the bearing capacity of the offshore construction platform. The setting of the middle enclosure 34 can limit the shape of the floating bags 35 after expansion, so that they can only expand downward, and on the other hand, the entire enclosure can protect the floating bags 35 from floating objects in the sea or other damage.

[0042] Embodiment 2:

[0043] A chain 36 is ball-hinged at the center of the bottom of the buoy base 1, and a balancing ball 37 is suspended at the bottom of the chain 36. Through the suspended balancer, when the buoy base 1 is tossed or swayed under the impact of wind and waves, the balancing ball 37 connected by the free ball can always keep the center of gravity vertical to the horizontal plane, providing a downward pulling force on the buoy base 1, thereby increasing the difficulty of the buoy base 1 to break away from the sea surface, that is, to capsize. In combination with the connecting mechanism 5 and the balancing mechanism 3, the offshore construction platform is more stable and safer.

[0044] A spring 38 is welded to the outside of the balancing ball 37, and a ball segment 39 is welded to the free end of the spring 38. When marine creatures in a hurry hit the balancing ball 37, they will first encounter the ball segment 39 and the spring 38. The process of the two being compressed is the buffering process, which can reduce the damage to marine creatures. In addition, there are also many floating garbage in the ocean, and the extended multiple ball segments 39 are equivalent to multiple tentacles, which can intercept other soft floating garbage such as films and gauze and wrap around the ball segments 39, so that marine garbage can be processed when recovering offshore construction platforms.

[0045] Embodiment 3:

[0046] Pile holes 6 are also provided on both sides of the buoy base 1, and at least two of the pile holes 6 are provided; the buoy base 1 is provided with a guide mechanism 7 around the pile holes 6. The guide mechanism 7 includes a plurality of columns 8, which are fixed on the buoy base 1 and distributed along the circumference of the pile holes 6, and a telescopic column 9 is fixedly installed on the column 8, and a ball 10 is connected to the telescopic end of each telescopic column 9; by changing the telescopic length of the telescopic column 9, it is suitable for installation of single pile foundations of different sizes. When installing a single pile foundation, it is necessary to install the single pile foundation at a specified position and ensure that the single pile foundation falls vertically, otherwise the degree of skewness of the single pile foundation will be magnified during the subsequent hammering process, resulting in failure in the installation of offshore wind power equipment; therefore, an electric or pneumatic telescopic column 9 is installed in the present invention, and the balls 10 at the ends of the multiple telescopic columns 9 form arc surfaces of different diameters, so that it is suitable for single pile foundations of different diameters. During installation, it is only necessary to insert the single pile foundation into the pile hole 6 and then synchronously adjust the extension of the multiple telescopic columns 9 until each ball 10 is pressed against the surface of the single pile foundation. At this time, the positioning of the single pile foundation is formed, and then the single pile foundation is slowly lowered, and under the action of the arc surface formed by the combination of the multiple balls 10, it always keeps moving vertically downward, so that the single pile foundation can be installed in place at one time.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
