Description

Technical Field

[0001] The present application relates to the technical field of offshore wind power foundation equipment, and more specifically, to an assembled offshore wind power foundation. Background Art

[0002] Due to its advantages such as stable wind energy and high density, offshore wind power has gradually developed into an important form of wind power generation worldwide. In deep waters, wind energy resources are more abundant, and the wind turbulence intensity and sea surface roughness are smaller than those in the near sea. Therefore, the research and development of offshore wind power technology in deep waters has become a new trend in the development of offshore wind power today. However, the traditional wind power foundation is not only complicated and time-consuming to install, but also difficult to apply to deep sea areas. In order to improve the installation efficiency and economy of offshore wind power foundations, prefabricated offshore wind power foundations that can be quickly installed have been increasingly widely used.

[0003] The document with prior art publication number CN216892499U provides an assembled offshore wind power floating foundation structure. The assembled design of the device greatly reduces the requirements for steel structure processing plants, transportation and installation ships and docks, reduces the construction difficulty and threshold, and provides a reliable idea for mass production of wind farm construction.

[0004] Although the above-mentioned existing technical solutions have effectively reduced the difficulty of installing wind power foundations to a certain extent, they still have the following defects: the above-mentioned technical solutions and most of the existing floating foundations use a mooring system consisting of an anchor machine and an anchor chain to fix the floating foundation body. When there are extremely windy weather at sea, the floating foundation body will be blown to one side by the wind, and the anchor chain on the opposite side below it is likely to bear a tensile force that exceeds its designed bearing capacity. This will not only cause damage to the anchor chain and reduce the service life of the anchor chain, but it is also likely to affect the normal operation of the wind power generation system. In view of this, we propose an assembled offshore wind power foundation. Summary of the invention

[0058] The counterweight shell 901 is fixedly installed on the lower side of the installation shell 2, the drain valve 904 is installed below the counterweight shell 901, the input end of the water pump is fixedly connected to a water suction pipe 906, the end of the water suction pipe 906 is installed with a filter screen 907, the output end of the water pump is fixedly connected to a water supply pipe 905, the bearing ring 902 is rotatably embedded in the counterweight shell 901, the water supply pipe 905 passes through one side of the bearing ring 902 and is connected to the inner cavity of the installation shell 2, and a number of overflow ports 912 are also installed above the counterweight shell 901.

[0059] On the basis of the above scheme, the embodiment of the present application discloses an assembled offshore wind power foundation, in which a water diversion ring is fixedly installed on the inner side of the bearing ring 902, and a plurality of water outlet pipes 903 are fixedly connected to the water diversion ring.

[0060] On the basis of the above scheme, the embodiment of the present application discloses an assembled offshore wind power foundation, in which the water pump includes a sealing shell 908 , a receiving rod 910 and a water pumping blade 911 .

[0061] The sealing shell 908 is fixedly installed on the mounting shell 2, the pumping pipe 906 is fixedly connected to the end of the sealing shell 908, the water supply pipe 905 is fixedly connected to the other side of the sealing shell 908, the receiving rod 910 is rotatably arranged in the sealing shell 908, and the pumping blade 911 is fixed on the receiving rod 910 in a ring shape. The fourth bevel gear 909 is fixedly connected to the receiving rod 910 and the active rod 3, and the two fourth bevel gears 909 are vertically meshed.

[0062] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an assembled offshore wind power foundation. After the installation base 1 and the buoy 12 are set in the designated sea area by using the catenary 14 and the suction anchor 15, the staff installs the wind turbine on the installation base 1. When extremely windy weather occurs, under the action of the first motor 11, the active rod 3 rotates. Since the two first bevel gears 10 are vertically meshed with each other, the driving rod 4 will drive the propeller 6 to rotate rapidly to generate thrust, and push the installation base 1 and the buoy 12 in the opposite direction of the wind, thereby effectively reducing the tension on the catenary 14 and the suction anchor 15 on the windward side, thereby reducing the probability of damage to the overall mooring system and effectively extending its service life.

[0063] Reference Figure 1 and Figure 3When there is strong wind at sea, the wind vane 703 will be blown to one side by the strong wind, and the rotating sleeve 701 and the connecting ring 702 will move with it and point to one side. The infrared tracking module 706 will send a signal to the control module 707. Under the control of the control module 707, the second motor 708 will run and the driving gear 704 will rotate until the driving ring 13 drives the mounting shell 2 on one side to move to the same direction as the wind vane 703, without manual adjustment. In addition, the connecting ring 702 can increase the friction between the mounting base 1 to prevent the wind vane 703 from rotating at will in the case of light wind or small wind.

[0064] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The embodiment of the present application discloses an assembled offshore wind power foundation. When the propeller 6 is not rotating, two protective covers 801 are arranged on the outside of the propeller 6 to avoid collision with marine organisms or garbage. This can not only protect marine organisms, but also reduce the probability of damage to the propeller 6. When the first motor 11 is running and the propeller 6 is rotating, the active disk 810 rotates rapidly under the connection between the second bevel gear 802 and the third bevel gear 809. Under the action of centrifugal force, the guide rod 813 will be thrown out and gradually extend into the slot 812. At this time, the driving sleeve 811 will drive the connecting gear 805 to rotate, causing the protective cover 801 to unfold to both sides. When the first motor 11 stops running and the propeller 6 stops rotating, under the action of the third spring 815, the guide rod 813 will shrink into the installation slot 814. At this time, the second spring 808 is reset, and the driving rack 803 can drive the electric protective cover 801 to reset smoothly to the inside.

[0065] Reference Figure 1 , Figure 6 and Figure 7In windy weather, when the active rod 3 rotates, due to the connection of the fourth bevel gear 909, the receiving rod 910 will drive the pumping blade 911 to rotate rapidly. After the seawater is filtered by the filter screen 907, it enters the water diversion ring through the pumping pipe 906 and the water supply pipe 905, and falls evenly into the counterweight shell 901 through the outlet pipe 903, so that the weight of the counterweight shell 901 is increased, and the overall draft weight of the device is increased, thereby effectively improving the wind resistance performance of the technical solution. The setting of the overflow port 912 can prevent excessive seawater inside the counterweight shell 901. That is to say, by adopting the above-mentioned technical scheme, when the mounting base 1 tends to shake, the seawater will enter the counterweight shell 901 after being filtered through the filter net 907, which can increase the weight of the counterweight shell 901 and improve the overall draft of the device, thereby effectively improving the wind resistance of the technical scheme; the setting of the overflow port 912 can prevent excessive seawater inside the counterweight shell 901; in addition, the setting of the water dividing ring and the outlet pipe 903 allows the seawater to fall evenly into the counterweight shell 901.

[0066] The implementation principle of an assembled offshore wind power foundation in an embodiment of the present application is as follows: when using the present technical solution to install wind turbine equipment, if extremely windy weather occurs, the wind deflector 703 will be blown to one side by the strong wind, and the rotating sleeve 701 and the connecting ring 702 will follow and move, and point to one side.

[0067] At this time, the infrared tracking module 706 will send a signal to the control module 707. Under the control of the control module 707, the second motor 708 will run, the driving gear 704 will rotate, and the driving ring 13 will drive the mounting shell 2 on one side to move to the same direction as the wind deflector 703.

[0068] Then, under the action of the first motor 11, the active rod 3 rotates, and under the connection between the second bevel gear 802 and the third bevel gear 809, the active disk 810 rotates rapidly. Under the action of centrifugal force, the guide rod 813 will be thrown out and gradually extend into the slot 812. At this time, the driving sleeve 811 will drive the connecting gear 805 to rotate, prompting the protective cover 801 to unfold to both sides.

[0069] During this period, since the two first bevel gears 10 are vertically meshed with each other, the driving rod 4 will drive the propeller 6 to rotate rapidly to generate thrust, pushing the mounting base 1 and the buoy 12 in the opposite direction to the wind.

[0070] In addition, due to the connection function of the fourth bevel gear 909, the receiving rod 910 will drive the pumping blade 911 to rotate rapidly.
