At the same time, the power generated by the wind turbine 15 is also stored in the battery group 67, which plays an auxiliary power supply role for the four generators 66 and provides sufficient power supply for the power-consuming components. At the same time, it does not completely rely on the power generation supply of the wind turbine 15, avoiding affecting the overall power generation and energy storage efficiency of the wind turbine 15, providing power supply for subsequent power-consuming components, saving power resources, and reducing the cost of navigation instructions for ships in the wind farm area;

[0048] The driving assembly 7 also includes a first main bevel gear 72 fixed on the piston rod of the electric telescopic rod 71, and the other side of the inner cavity of the top frame 4 is rotatably connected to a differential bevel gear 73 used in conjunction with the first main bevel gear 72. The electric telescopic rod 71 first adjusts the meshing stroke between the first main bevel gear 72 and the differential bevel gear 73. The bottom of the differential bevel gear 73 is meshed with a secondary bevel gear 74, and the natural wind force formed by the sea breeze captured by the fan 62 on the rotating shaft 61 is used as a driving source, and the differential bevel gear 73 and the secondary bevel gear are successively driven by the first main bevel gear 72 that is meshed in place. The wheel 74 rotates, using natural wind as a driving source, and an electric push rod 76 is embedded in the output shaft of the servo motor 75. The piston rod of the electric push rod 76 is fixedly connected to the second main bevel gear 77 used in conjunction with the auxiliary bevel gear 74. If the wind force is insufficient, the electric push rod 76 adjusts the meshing stroke between the second main bevel gear 77 and the auxiliary bevel gear 74, and then the servo motor 75 provides a mechanical driving power source, and the auxiliary bevel gear 74 and the differential bevel gear 73 are driven to rotate in succession through the second main bevel gear 77, providing a mechanical driving source for them, thereby reducing the cost of the driving source;

[0049] The lifting assembly 8 includes limiting slide grooves 81 provided on both sides of the top cylinder 3, and the bottom of the secondary bevel gear 74 is fixedly connected with a reciprocating screw rod 82 that rotates with the top frame 4 and the top cylinder 3. After the wind driving source and the mechanical driving source are combined, the secondary bevel gear 74 first drives the reciprocating screw rod 82 to rotate, and the reciprocating screw rod 82 is threadedly connected with a screw rod tube 83, and the outer sleeve of the screw rod tube 83 is provided with a double-sided gear rack 84. The reciprocating screw rod 82 drives the double-sided gear rack 84 to perform reciprocating lifting and lowering movements through the screw rod tube 83. Both sides of the double-sided gear rack 84 are fixedly connected with connecting frames 85 that slide with the limiting slide grooves 81, and the outer side of the connecting frame 85 is fixedly connected with a line frame 86, and the outer side of the line frame 86 is fixedly connected with indicator lights 87. The double-sided gear rack 84 drives the indicator lights 87 on the two groups of line frames 86 through two groups of connecting frames 85 to perform lifting dynamic light indication on ships in both directions, thereby improving the passing safety of passing ships in the wind farm area.

[0050] The knocking assembly 9 includes a sound collecting cavity 91 opened in the sealed box 5, and the main reed 92 and the auxiliary reed 93 are fixed circumferentially around the sound collecting cavity 91, and the inner cavity of the differential bevel gear 73 is fixedly connected with a rotating rod 94 that rotates with the top frame 4 and the sealed box 5, and the rotating rod 94 is fixedly connected with a main knocking head 95 and an auxiliary knocking head 96 used in conjunction with the main reed 92 and the auxiliary reed 93 around the rotating rod 94, and the rotating rod 94 is driven by the differential bevel gear 73 to rotate, and the rotating rod 94 drives the main knocking head 95 and the auxiliary knocking head 96 to rotate synchronously, and the sealed box The outer side of the wind turbine 5 is fixedly connected with a loudspeaker 97 used in conjunction with the sound collecting cavity 91. The main knocking head 95 and the auxiliary knocking head 96 in a rotating state knock the main reed 92 and the auxiliary reed 93 distributed on the circumference at a frequency, and after generating a warning sound in the sound collecting cavity 91, the loudspeaker 97 amplifies the sound and broadcasts it to the surrounding sea area, which plays an effective sound guide to the surrounding ships, especially in severe weather with low visibility due to heavy fog. It is also suitable for sound warning to ships in calm weather, further improving the safety of ships passing through the wind farm area;

[0051] The thickness of the main reed 92 is less than that of the secondary reed 93. By changing the thickness of the main reed 92 and the secondary reed 93, the main striking head 95 and the secondary striking head 96 can make crisp and heavy sounds when striking the main reed 92 and the secondary reed 93 respectively, so as to be mixed and collected in the sound collecting cavity 91, and the main reed 92 is distributed in an axially symmetrical state along the secondary reed 93. The head ends of the main striking head 95 and the secondary striking head 96 that strike the main reed 92 and the secondary reed 93 are both designed as spherical, and the sphere is solid, which can effectively strike the main reed 92 and the secondary reed 93, and is conducive to the vibration sound between the main reed 92 and the secondary reed 93.

[0052] like Figure 16-18As shown, the indicator light devices currently used for indicating passing ships mostly provide static indication from a single direction and do not have a multi-directional dynamic indication function, resulting in the safety of ships passing through the wind farm area cannot be guaranteed. A swing assembly 10 is provided on both sides of the lifting assembly 8, and the swing assembly 10 includes a transfer circular gear 101 meshed on both sides of the double-sided gear rack 84 and rotating with the top cylinder 3. A swing arm 102 is fixedly connected to the transfer circular gear 101. The double-sided gear rack 84 in a reciprocating lifting state drives the two groups of transfer circular gears 101 to rotate at a forward and reverse frequency. The two groups of transfer circular gears 101 drive the two swing arms 102 to swing at a forward and reverse frequency, and the inner side of the swing arm 102 is fixedly connected to a limit slider 103 that slides with the top cylinder 3. The limit slider 103 plays the role of sliding support between the swing arm 102 and the top tube 3. The outer side of the swing arm 102 is fixedly connected to the circuit box 104, and the outer array of the circuit box 104 is embedded with main lamp beads 105, and both sides of the circuit box 104 are embedded with auxiliary lamp beads 106. The two swing arms 102 with positive and reverse frequency swinging motion drive the main lamp beads 105 and auxiliary lamp beads 106 on the two groups of circuit boxes 104 to swing back and forth, which plays a swinging dynamic indication for ships in the other two directions, further improving the safety of ships passing through the wind farm area, and the swing arm 102 is slidably connected with an arc-shaped slide 107 fixedly matched with the top tube 3, which plays the role of sliding limit for the swing arm 102 in the swinging state, thereby improving the swinging stability of the swing arm 102.

[0053] The working principle of a navigation aid device for ships: first, the floating platform 1 provides overall buoyancy support for the navigation aid device, and the positioning rod 12 and the mounting flange lock the floating platform 1 in the installation position, and the weight-bearing seat 14 at the bottom of the anchor chain 13 performs weight-bearing dragging and limiting on the floating platform 1, so that the navigation aid device as a whole tends to be stable, and then the high-efficiency navigation light 11 in the light frame 2 provides navigation light indication to the surrounding sea areas in four directions through the window, and the wind catcher 62 on the rotating shaft 61 captures the sea breeze, and driven by natural wind, the wind catcher The fan 62 forces the driving bevel gear 63 on the rotating shaft 61 to rotate, and the driving bevel gear 63 drives the power generation shaft 65 on the four sets of driven bevel gears 64 to rotate and do work in the four sets of generators 66. The four sets of generators 66 store the generated electric energy in the battery pack 67 to provide wind power generation supply for the electrical components. At the same time, under the premise of not affecting the overall power generation and energy supply of the wind turbine 15, the surplus power of the wind turbine 15 will also provide part of the power supply to the battery pack 67, so that the power consumption of the electrical components is fully guaranteed;

[0054] If the sea breeze is strong, the electric telescopic rod 71 is first controlled to open and drive the first main bevel gear 72 to move down to the meshing part of the differential bevel gear 73, and the natural wind captured by the fan 62 is used as the driving source, and the first main bevel gear 72 and the driving bevel gear 63 are driven to rotate synchronously through the rotating shaft 61, and the first main bevel gear 72 engaged in place drives the differential bevel gear 73 to rotate, and the differential bevel gear 73 then drives the auxiliary bevel gear 74 to rotate accordingly, providing a wind driving source for the subsequent dynamic indication of the light. If the sea breeze is weak, the electric telescopic rod 71 is first controlled to open and drive the first main bevel gear 72 to move down to the meshing part of the differential bevel gear 73, and the first main bevel gear 72 engaged in place drives the differential bevel gear 73 to rotate, and the differential bevel gear 73 then drives the auxiliary bevel gear 74 to rotate accordingly, providing a wind driving source for the subsequent dynamic indication of the light. The rod 71 is closed and drives the first main bevel gear 72 to move up and disengage the meshing portion of the differential bevel gear 73 to the initial position. After the conduction path of natural wind is disconnected, the electric push rod 76 is controlled to open and drive the second main bevel gear 77 to move forward and clamp to the meshing portion of the auxiliary bevel gear 74. Then the servo motor 75 is controlled to open and drive the auxiliary bevel gear 74 to rotate through the second main bevel gear 77 that is meshed in place. The auxiliary bevel gear 74 then drives the differential bevel gear 73 to rotate accordingly. At this time, the rotating rod 94 drives the first main bevel gear 72 to be in an idling state, and the two sets of driving source modes do not affect wind power generation.

[0055] According to the strength of the current sea breeze, after flexibly obtaining natural wind force and mechanical power drive, the rotating secondary bevel gear 74 drives the reciprocating screw 82 to rotate, and the reciprocating screw 82 drives the double-sided gear rack 84 on the screw cylinder 83 to move back and forth, and the double-sided gear rack 84 drives the two sets of connecting frames 85 to slide back and forth in the limiting slide groove 81, and the two sets of connecting frames 85 drive the indicator lights 87 on the two sets of line frames 86 to move back and forth, and provide lifting dynamic light indications to ships in the sea areas in two directions of the wind farm. At the same time, The double-sided gear rack 84 with compound lifting motion also drives the two sets of transfer circular gears 101 to rotate at forward and reverse frequencies. The two sets of limit sliders 103 and the arc-shaped slide 107 play the role of sliding limit for the two swing arms 102. Then, the two sets of transfer circular gears 101 drive the two sets of line boxes 104 to swing at forward and reverse frequencies through the two swing arms 102. Then, the two sets of line boxes 104 swinging at forward and reverse frequencies also drive the two sets of main lamp beads 105 and auxiliary lamp beads 106 to move accordingly, and provide swing-type dynamic light indication to ships in the other two directions of the wind farm.

[0056] At the same time, the rotating differential bevel gear 73 drives the rotating rod 94 to rotate in the sealing box 5, and the rotating rod 94 drives the main knocking head 95 and the auxiliary knocking head 96 to rotate synchronously. The rotating main knocking head 95 and the auxiliary knocking head 96 correspondingly knock the main reed 92 and the auxiliary reed 93 distributed in a circular shape, and make a sound in the sound collecting cavity 91. The loudspeaker 97 then amplifies the sound emitted from the sound collecting cavity 91 and propagates it to the ships passing by the sea area of ​​the wind farm, so as to give them a sound warning, especially in severe weather with heavy fog and low visibility.

[0057] It should be noted that the specific models and specifications of the generator 66, the electric telescopic rod 71, the electric push rod 76 and the loudspeaker 97 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0058] The power supply circuits of the generator 66, the electric telescopic rod 71, the electric push rod 76 and the loudspeaker 97 are clear to those skilled in the art and will not be described in detail herein.
