[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 3 As shown, one embodiment of the present invention provides a throwing device for wind turbine foundation protection, comprising: a first throwing device 1 and a second throwing device 2 that can be mated with the first throwing device 1. By providing these mating throwing devices, the sand blanket can be hoisted and thrown for installation, facilitating wind turbine foundation protection. Accordingly, the external throwing platforms 13 of the first and second throwing devices 1, 2, are further provided with hinge holes 10 at the mating connection locations.
[0023] Specifically, each throwing device 1 or 2 includes an internal throwing platform 11, a cylinder 12, an external throwing platform 13, and a decoupling mechanism 14. The internal throwing platform 11 is connected to the inner side of the cylinder 12, and the external throwing platform 13 is connected to the outer side of the cylinder 12.
[0024] In order to match with wind turbine piles of different sizes and complete the throwing installation of the sand blanket, the internal throwing platform 11 includes: an internal throwing platform body 111, a wheel box 112 and a diameter-changing rod 113.
[0025] In order to adapt to the wind turbine pile, the internal throwing platform body 111 is configured as two separate parts, each part has an arc, and a connecting hole 1110 is provided at the docking position of the two parts.
[0026] The internal throwing platform body 111 is welded to the inner wall of the cylinder 12. One end of the wheel box 112 is hinged to the inner wall of the cylinder 12. The variable diameter rod 113 is hinged to the inner wall of the cylinder 12 at one end and to the wheel box 112 at the other end. This arrangement allows the wheel box 112 and the variable diameter rod 113 to be hinged to the cylinder 12, allowing the wheel box 112 to remain mobile and thus able to contact the wind turbine pile regardless of its size. Furthermore, to protect the surface of the wind turbine pile, a roller 114 is connected to the other end of the wheel box 112.
[0027] The external throwing platform 13 forms the main structure of the throwing device, facilitating the lifting of sand blankets of appropriate size. The external throwing platform 13 includes an external throwing platform body 131 and diagonal braces 132. The external throwing platform body 131 is welded to the outer wall of the cylinder 12, and the diagonal braces 132 connect the cylinder 12 and the external throwing platform body 131 to enhance the connection strength between the external throwing platform body 131 and the cylinder 12.
[0028] The unhooking mechanism 14 is used to realize automatic unhooking of the sand blanket, and includes: a connecting rod 141 and a plurality of unhooking components 142 . The plurality of unhooking components 142 are arranged at intervals at the bottom of the internal throwing platform 11 and the external throwing platform 13 and are linked by the connecting rod 141 .
[0029] Each decoupling assembly 142 includes a bearing 1421, a pin 1422, a lifting lug 1423, and a lifting rope 1424. The pin 1422 is inserted into the bearing 1421. One end of the lifting rope 1424 is connected to the lifting lug 1423 above the pin 1422, and the other end is connected to the pin 1422. The pins 1422 of each decoupling assembly 142 are connected to the connecting rod 141 and are linked by the connecting rod 141. Accordingly, the suspended sand quilt is also provided with a lifting ring, and the lifting rope 1424 is inserted into the lifting ring of the sand quilt. With this arrangement, when the connecting rod 141 is pulled, the pins 1422 of each decoupling assembly 142 can be driven to move synchronously. When the pins 1422 are separated from the ring of the lifting rope 1424, the sand quilt can be decoupled and released. In addition, in order to limit the movement of the pull rod, a baffle 1411 is further provided at one end of the connecting rod 141 .
[0030] To operate the wind turbine foundation protection throwing system, first pre-assemble the first and second throwing devices. The vessel then navigates to the work area and installs the sand blanket. The wind turbine foundation protection throwing system is hoisted and initially positioned. The first and second throwing devices are hinged together, and the lower portion of the wind turbine foundation protection throwing system is brought to the desired height. A connecting rod pulls the pin to unhook the sand blanket, completing the sand blanket installation. The hinges are then released, and the hoisting platform is returned to the deck, allowing the vessel to prepare for the next round of installation.
[0031] In summary, the wind turbine foundation protection throwing equipment of the present invention, by providing a cooperable throwing device, can complete the hoisting and throwing installation of the sand blanket, thus facilitating wind turbine foundation protection. During the throwing installation, the sand blanket can also be automatically unhooked, making operation more convenient. Furthermore, the sand blanket can be used with wind turbine piles of different sizes to complete the throwing installation.
