[0034] Reference Figure 1 and Figure 2 As an embodiment of this utility model, a protective device for a rotor sail 600 includes a support assembly 100, a power assembly 200, a winch assembly 300, and a protective net 400. The support assembly 100 includes a support body 101 and a support rod 107. The support body 101 is welded to the deck, and the bottom of the support rod 107 is rotatably connected to the support body 101. The power assembly 200 includes a power source and a telescopic drive component. One end of the telescopic drive component is hinged to the support body 101, and the other end is hinged to the support rod 107. At the top position of 07, the power source drives the telescopic drive component to extend and retract. After the telescopic drive component extends and retracts, it can drive the support rod 107 to support or fall down. The winch device 300 includes a manual winch 301 and a steel wire rope 302. The steel wire rope 302 can be wound on the manual winch 301. The free end of the steel wire rope 302 is provided with a shackle 304. The edge of the protective net 400 is provided with a first ring 403. The first ring 403 is connected to the shackle 304. The winch device 300 can tighten and fix the protective net 400 to the rotor sail 600.

[0035] Four sets of support components 100 are located on either side of the two ends of the rotor sail 600. Each support component 100 is equipped with a power unit 200 and a winch device 300. The power source drives the telescopic drive component to extend, which in turn drives the support rod 107 to a vertical position for support. When the support rod 107 is erected, it is higher than the highest point of the main body of the rotor sail 600. The protective net 400 is fixed to the four sets of support rods 107 by a manual winch 301 and a steel wire rope 302, covering most of the top of the rotor sail 600. This effectively protects the rotor sail 600 from large amounts of ore leaking from the shore crane grab bucket from falling directly or impacting it.

[0036] Specifically, refer to Figures 3 to 7The support body 101 is a metal structure welded to the deck, providing a stable base for the entire tiltable support rod 107. A pin 105 is mounted on the support body 101. The pin 105 is made of round steel with cotter pins at both ends. The pin 105 connects the support rod 107 to the support body 101 through an opening in the support body 101 and serves as the rotation axis of the support rod 107. The power source is a pump station 201, with a pump station base 112 mounted on the support body 101. The pump station 201 can be electric or manual. The telescopic drive component is a hydraulic cylinder 205. The pump station 201 stores hydraulic oil and provides power for the entire hydraulic system. An upper hydraulic cylinder support 108 and a lower hydraulic cylinder support 102 are mounted on the support body 101. The upper hydraulic cylinder support 108 is welded to the support rod 107 and connected to the upper end of the hydraulic cylinder 205 via a pin, providing sufficient strength support for the hydraulic cylinder 205. The lower support 102 of the hydraulic cylinder is a metal structure with a perforated plate, welded to the main body 101 of the bracket. It is connected to the lower end of the hydraulic cylinder 205 via a pin, providing sufficient strength support for the hydraulic cylinder 205. The power assembly 200 also includes a hydraulic hose 202, a hydraulic lock 203, and a tee connector 204. The hydraulic hose 202 connects the pump station 201 to the hydraulic lock 203, and also connects the hydraulic lock 203 to the hydraulic cylinder 205, supplying hydraulic oil. A hydraulic lock base 110 is welded to the main body 101 of the bracket. The hydraulic lock 203 is installed on the hydraulic lock base 110 to maintain the pressure of the system pipeline in the event of a sudden interruption during the operation of the pump station 201, ensuring that the support rod 107 will not fall. The tee connector 204 is installed between one end of the hydraulic cylinder 205 hose and the hydraulic lock 203, ensuring that a single pump station 201 can control two hydraulic cylinders 205. The hydraulic cylinder 205 is the power output component of the hydraulic system, which can raise and lower the support rod 107 when operating the pump station 201. The support assembly 100 also includes a limiting support 111, which is located on one side of the support body 101. The limiting support 111 provides support when the support rod 107 is in the fallen state, thus avoiding interference with other equipment and facilities on the deck.

[0037] Furthermore, the support body 101 is provided with an opening, and a limit pin 104 is slidably connected to the opening. The support rod 107 is provided with a limit hole. After the support rod 107 is rotated to the vertical direction, the limit pin 104 passes through the opening and is inserted into the limit hole.

[0038] Specifically, the limiting pin 104 is made of round steel, with an operating handle and a cotter pin at one end. When the support rod 107 is in the upright position, the limiting pin 104 passes through the opening in the support body 101, serving as a mechanical limit. A pin support 103 is fixed on the support body 101, supporting the pin. When the support rod 107 is in the lowered position or during operation, the limiting pin 104 is pulled out of the support body 101 and rests on the pin support 103. The pin support 103 is made of angular metal, with one end welded to the support body 101, facing downwards at a right angle, and supporting the limiting pin 104 above, facilitating personnel operation. The hydraulic drive lowers or raises the support rod 107, and the operation can be stopped and reversed at any time during operation. Compared with the previous manual counterweight scheme, this greatly reduces the difficulty of operation and the total weight of the device, while also reducing costs and improving operational safety.

[0039] Furthermore, referring to Figure 8 The support rod 107 is equipped with a winch base 106, and a manual winch 301 is mounted on the winch base 106. The support rod 107 also has a guide wheel 303, which guides the wire rope 302. The winch base 106 is a metal structure base welded to the support rod 107. The manual winch 301 is bolted to the winch base 106. The wire rope 302 is wound up and stored on the manual winch 301, with a shackle 304 at the end for movable connection to the protective net 400. Guide wheels 303 are welded to the middle and top of the support rod 107, guiding the wire rope 302.

[0040] Furthermore, referring to Figure 9 The protective net 400 includes a small-mesh nylon mesh 401 and a plastic-coated steel wire rope 402. The plastic-coated steel wire rope 402 is distributed around the perimeter and center of the small-mesh nylon mesh 401, and connecting loops 504 are fixed to the plastic-coated steel wire rope 402. The small-mesh nylon mesh 401 is lightweight and, when pulled up, is positioned on the top and sides of the rotor sail 600 to prevent mineral sand larger than the mesh size from falling directly onto the sail. The plastic-coated steel wire rope 402 strengthens the structural strength of the small-mesh nylon mesh 401. A first loop 403 is used to connect to the steel wire rope 402, providing several fixing points.

[0041] Furthermore, the rotor sail 600 protection device also includes a tension lock 500, which includes a first fastening rope 501, one end of which is fixed to the deck and the other end is connected to a support rod 107.

[0042] Specifically, refer to Figure 10The first fastening rope 501 has connecting buckles at both ends, and the support rod 107 has connecting ears 109. One end of the first fastening rope 501 is fixed to the deck, and the other end is connected to the connecting ear 109. The first fastening rope 501 is used to provide tension in at least two directions to support the erection of the support and prevent swaying. The tensioning lock 500 also includes a second fastening rope 502. The edge of the protective net 400 has a second collar 404. One end of the second fastening rope 502 is fixed to the deck, and the other end is connected to the second collar 404. Both ends of the second fastening rope 502 have connecting buckles for easy connection. The second fastening rope 502 is used to fix the protective net 400 so that the protective net 400 covers most of the top of the rotor sail 600, preventing it from being blown up by external forces. The tightening lock 500 also includes a lock screw buckle 503, which is disposed on the first fastening rope 501 and the second fastening rope 502, and is used to adjust the tightness of the first fastening rope 501 and the second fastening rope 502.

[0043] After the Rotor Sail 600 is laid down, Figure 1 As shown, the support rods 107 on both sides are driven upright by the power assembly 200 and then locked in place by the limit pins 104. The support rods 107 are tightened and fixed by the first fastening rope 501 of the tightening lock 500. Then, the wire rope 302 on the manual winch 301 is connected to the first ring 403 on the protective net 400. After the protective net 400 is pulled over the rotor sail 600, the manual winch 301 is rotated to tighten the protective net 400 and cover the top and sides of the rotor sail 600. Finally, the second fastening rope 502 of the tightening lock 500 is connected to the second ring 404 on the protective net 400, thus completing the protective net 400 covering most of the top of the rotor sail 600, achieving the protective function.

[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
