[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a wind power generation device, which includes a base 10, a power generation mechanism 20 and a telescopic member 30. The power generation mechanism 20 includes a rotating blade 21, a blade shaft 22 and a power generation unit 23. The rotating blade 21 is arranged on the first end of the blade shaft 22. The power generation unit 23 is arranged in the base 10. The second end of the blade shaft 22 is penetrated by the base 10 and can be driven and connected with the power generation unit 23. The telescopic member 30 is telescopically arranged in the base 10. The moving direction of the telescopic member 30 is parallel to the axial direction of the blade shaft 22. The telescopic member 30 can abut against the power generation unit 23 to drive the power generation unit 23 to move toward the direction of the rotating blade 21. The fire protection component 40 includes a detection member, a control member And a spray member 41, the spray member 41 and the detection member are both arranged in the base 10, and the water outlet of the spray member 41 is arranged in the direction of the power generation unit 23, the control member is respectively connected with the detection member and the spray member 41 by signal, so as to control the spray member 41 to spray the power generation unit 23 according to the detection signal of the detection member, wherein the power generation unit 23 has a first position for cooperating with the blade shaft 22 to store electricity and a second position separated from the blade shaft 22, when the power generation unit 23 is in the first position, the telescopic member 30 is in an extended state, and the motor shaft of the power generation unit 23 is abutted against the second end of the blade shaft 22, and when the power generation unit 23 is in the second position, the telescopic member 30 is in a retracted state, and the power generation unit 23 is separated from the second end of the blade shaft 22.

[0028] The wind power generation device provided by the present embodiment includes a base 10, a power generation mechanism 20, a telescopic member 30 and a fire-fighting component 40. The rotating blade 21 is arranged on the first end of the blade shaft 22, and the power generation unit 23 is arranged in the base 10, so that the rotating blade 21 can convert wind energy into mechanical energy when it rotates, and the rotation of the rotating blade 21 can also drive the blade shaft 22 to rotate. The second end of the blade shaft 22 is penetrated by the base 10 so that the blade shaft 22 can be driven and connected to the power generation unit 23, thereby ensuring that the power generation unit 23 can be driven to generate electricity under the action of the blade shaft 22. The telescopic member 30 is telescopically arranged in the base 10, and the moving direction of the telescopic member 30 is parallel to the axial direction of the blade shaft 22. The telescopic member 30 can abut against the power generation unit 23, and then the power generation unit 23 can be driven to move under the action of the telescopic member 30, so that the power generation unit 23 can move in the base 10 and move toward the direction of the blade, so that the power generation unit 23 can be driven and connected with the second end of the blade shaft 22, so that the power generation unit 23 can achieve the function of power generation and storage, and then the wind power generation device can convert wind energy into electrical energy. A firefighting component 40 is arranged in the base 10, and the firefighting component 40 includes a detection component, a control component and a spray component 41. The spray component 41 and the detection component are both arranged in the base 10, and the water outlet of the spray component 41 is arranged in the direction of the power generation unit 23. When the power generation unit 23 is damaged and a fire occurs, the signal detected by the detection component is transmitted to the control component, and the control component controls the spray component 41 to spray water, so that the power generation unit 23 can be extinguished. Specifically, when the power generation unit 23 converts wind energy into electrical energy for storage, the telescopic part 30 extends to drive the power generation unit 23 and the blade shaft 22 to drive each other, so that the power generation unit 23 can be in the first position. When the power generation unit 23 is damaged and the spray part 41 is used for fire fighting, it is necessary to use the telescopic part 30 to change from an extended state to a retracted state, and the power generation unit 23 is separated from the second end of the blade shaft 22. In this way, the power generation unit 23 can be prevented from being driven to work while the blade shaft 22 and the rotating blades 21 continue to rotate, thereby preventing the power generation unit 23 from being further damaged, thereby improving the practicality of the wind power generation device.

[0029] like Figure 1 and Figure 2As shown, the power generation unit 23 is a generator, the rotation axis of the blade shaft 22 coincides with the rotation axis of the motor shaft of the generator, and a linkage mechanism 50 is provided between the motor shaft of the generator and the blade shaft 22, so that the motor shaft of the generator and the blade shaft 22 can rotate synchronously. With the above structure, by coinciding the rotation axis of the blade shaft 22 with the rotation axis of the generator, the telescopic member 30 drives the power generation unit 23 to move in the direction of the blade shaft 22, and then the motor shaft of the generator can be matched with the blade shaft 22 under the action of the linkage mechanism 50, so that the motor shaft of the generator and the blade shaft 22 can rotate synchronously, and then the generator is used to achieve the function of power generation.

[0030] like Figure 1 and Figure 2 As shown, the linkage mechanism 50 includes a protrusion and a recessed portion. The protrusion is arranged on the motor shaft of the generator. The protrusion is eccentrically arranged around the axis of the motor shaft of the generator. The recessed portion is arranged on the second end of the blade shaft 22 at a position corresponding to the protrusion. When the power generation unit 23 is in the first position, the protrusion is abutted against the recessed portion. When the power generation unit 23 is in the second position, the protrusion is separated from the recessed portion. By adopting the above structure, the protrusion is eccentrically arranged around the axis of the motor shaft of the generator, and the position of the recessed portion corresponding to the protrusion is arranged on the second end of the blade shaft 22. When the power generation unit 23 is in the first position, the protrusion can abut against the recessed portion. Since both the protrusion and the recessed portion are eccentrically arranged around the axis of the motor shaft of the generator, when the blade shaft 22 rotates, the protrusion abuts against the recessed portion, so that the motor shaft of the generator can rotate synchronously with the blade shaft 22, thereby facilitating the storage of electricity for the power generation unit 23. When the power generation unit 23 is in the second position, the protrusion only needs to be separated from the recessed portion to protect the power generation unit 23, so as to prevent the blade shaft 22 from continuing to drive the motor shaft of the generator to continue to rotate when the power generation unit 23 is damaged, thereby preventing the power generation unit 23 from being further damaged due to the blade shaft 22 continuing to drive the motor shaft of the generator to continue to rotate.

[0031] like Figure 1 and Figure 2As shown, the spray element 41 includes a nozzle 411, a water supply pipeline 412 and a pump body 413.

The first end of the water supply pipeline 412 is passed through the base 10 and is connected to the nozzle 411. The second end of the water supply pipeline 412 is connected to the water source. The pump body 413 is arranged on the water supply pipeline 412, and the control element is connected to the pump body 413 signal. By adopting the above structure, the first end of the water supply pipe 412 is passed through the base 10 and connected with the nozzle 411, and the second end of the water supply pipe 412 is connected with the water source. A pump body 413 is arranged on the water supply pipe 412, so that under the action of the pump body 413, the water from the water source can be transported to the nozzle 411 through the water supply pipe 412, so that the water outlet of the nozzle 411 can supply water to the power generation unit 23, which can play a role in fire fighting for the power generation unit 23.

[0032] like Figure 1 and Figure 2 As shown, a first opening is provided on the lower surface of the base 10, and the wind power generation device also includes a driving motor, a movable plate 61 and a cutting piece 62.

The power generation mechanism 20 also includes a connecting cable 24, a first end of the connecting cable 24 is connected to the power generation unit 23, and a second end of the connecting cable 24 passes through the first opening. The cutting piece 62 is arranged on the movable plate 61 to cut the connecting cable 24. By adopting the above structure, a driving motor is set to drive the movable plate 61 to move, so that the first opening can be blocked or opened. The cutting piece 62 is set on the movable plate 61, and the control component is connected to the driving motor signal. When the power generation unit 23 is damaged and is in the second position, in order to avoid further damage to the connecting cable 24, the control component is used to control the driving motor to move the movable plate 61 to block the first opening. When the movable plate 61 closes the first opening, the cutting piece 62 on the movable plate 61 can cut the connecting cable 24, thereby protecting the connecting cable 24 and avoiding damage to the connecting cable 24 when a fire occurs in the power generation unit 23.

[0033] like Figure 1 and Figure 2As shown, the wind power generation device also includes an isolation cabin 63 and a block 64. The isolation cabin 63 is arranged on the lower surface of the base 10. The isolation cabin 63 has a second opening and a third opening. The first opening can be connected to the second opening. The second end of the connecting cable 24 can pass through the first opening, the second opening and the third opening in sequence. The block 64 is arranged on the connecting cable 24. The size of the block 64 is larger than the size of the third opening so that the block 64 can stop at the third opening. By adopting the above structure, an isolation cabin 63 is provided on the lower surface of the base 10, and a block 64 is provided on the connecting cable 24. The size of the block 64 is larger than the size of the third opening. When the movable plate 61 closes the first opening, the cutting piece 62 cuts the connecting cable 24, so that part of the connecting cable 24 can be stopped at the third opening under the action of the block 64, avoiding the connecting cable 24 from falling directly to the ground after being cut. When it is necessary to connect the cut connecting cable 24 to the power generation unit 23, the maintenance personnel only need to climb onto the tower and directly connect the connecting cable 24 in the isolation cabin 63 to the power generation unit 23, so as to ensure that the power generation unit 23 can store electricity.

[0034] like Figure 1 and Figure 2 As shown, a counterweight block 241 is provided on the connecting cable 24, and the counterweight block 241 is located below the outside of the isolation cabin 63. With the above structure, the counterweight block 241 can ensure that the connecting cable 24 can fall down under the action of the counterweight block 241 after cutting, and stop at the third opening of the isolation cabin 63 under the action of the clamping block 64.

[0035] like Figure 1 and Figure 2 As shown, a mounting plate 11 is arranged in the base 10, the mounting plate 11 is arranged vertically, a connecting hole is arranged on the mounting plate 11, the second end of the blade shaft 22 is penetrated in the connecting hole, a clamping plate 221 is arranged on the blade shaft 22, the clamping plate 221 abuts against the mounting plate 11, and the size of the clamping plate 221 is larger than the size of the connecting hole.
