DETAILED DESCRIPTION

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] Reference Figure 1-Figure 9 The present embodiment provides a stacked wind power generation device, comprising a plurality of wind drive mechanisms, and all wind drive mechanisms are stacked up and down; the wind drive mechanism comprises a support frame 1, the support frame 1 is rotatably connected to a rotating rod 2, and a blade assembly 3 is detachably connected to the radial outer side of the rotating rod 2, and the blade assembly 3 is used to convert wind energy into mechanical energy for driving the rotating rod 2 to rotate; any two upper and lower adjacent support frames 1 are detachably connected, and any two upper and lower adjacent rotating rods 2 are detachably connected; all rotating rods 2 are coaxially arranged, and the rotating rod 2 at the end is transmission-connected to a generator 4.

[0033] The present embodiment is provided with a plurality of groups of wind drive mechanisms, and the upper and lower adjacent rotating rods 2 are detachably connected to form a total rotating rod. The blade assembly 3 in each group of wind drive mechanisms can capture natural wind energy and convert the wind energy into mechanical energy for driving the rotating rod 2 to rotate. Since all the rotating rods 2 form a total rotating rod, the thrusts generated by all the blade assemblies are superimposed on the total rotating rod, thereby increasing the thrust and rotation speed of the total rotating rod, and then superimposing all the mechanical energy acting on the rotating rod, and the generator set 4 converts the superimposed mechanical energy into electrical energy, thereby improving the power generation efficiency of the wind power generation device; and in the later stage, by increasing the number of wind drive mechanisms, the rotation speed of the total rotating rod, that is, the mechanical energy superimposed on the total rotating rod, can be further increased, and the maximum rated power generation efficiency of the wind power generation device can be further improved. There is no need to replace a new device, and it can be achieved only by superimposing a new wind drive mechanism, thereby reducing costs.

[0034] In this embodiment, a speed increaser 8 is provided between the rotating rod 2 and the generator 4. The speed increaser 8 is a gear set speed change mechanism. The low-speed rotational motion of the rotating rod 2 is converted into a high-speed rotational motion through the gear set speed change mechanism, and the high-speed rotational motion is transmitted to the generator 4 to ensure that the generator 4 can generate electricity normally. The blade assembly 3 can adopt an integrated structure or a split structure. When the blade assembly 3 adopts an integrated structure, the blade can be a turbine blade. The central axis position of the turbine blade is sleeved on the outside of the rotating rod 2, and the turbine blade is detachably connected to the rotating rod 2. The blade assembly 3 can capture natural wind energy and convert the wind energy into mechanical energy to drive the rotating rod 2 to rotate.

[0035] Further optimization scheme, the blade assembly 3 adopts a split structure, that is, the blade assembly 3 is sleeved on the outside of the rotating rod 2, and the blade assembly 3 includes a plurality of rotating arms 31 detachably connected to the rotating rod 2, and the rotating arms 31 are connected to blades 32. In this embodiment, the blades 32 capture wind energy, that is, wind with a certain wind speed acts on the blades 32, and the blades 32 and the rotating arms 31 begin to rotate under the action of the wind, driving the rotating rod 2 to rotate, and the blade assembly 3 converts the wind energy into mechanical energy to drive the rotating rod 2 to rotate. Compared with the integrated blade assembly 3, the blade assembly 3 in this embodiment is convenient for the maintenance and repair of the blade assembly 3 in the later stage, and the mechanical energy of the rotating rod 2 in each set of wind drive mechanism can be controlled by increasing or decreasing the number of blades 32 and rotating arms 31 in the later stage.

[0036] In this embodiment, the number of blades 32 in the blade assembly 3 is at least 3, that is, the number of blades 32 in the blade assembly 3 can be multiple, 4, 5, 6, 7 are all possible. The rotating rod 2 is arranged perpendicular to the ground, that is, arranged vertically; the rotating arms 31 in the same blade assembly 3 are in the same horizontal plane, that is, the rotating arms 31 in the same blade assembly 3 are arranged in a ring on the circumferential outer side of the rotating rod 2, and the rotating arms 31 in the same blade assembly 3 are evenly distributed on the outer side of the rotating rod 2, that is, the distance between any two adjacent rotating arms 31 is the same, so as to ensure that no matter what the wind direction is, at least one or more blades 32 can be affected by the wind force, and the advantage of the vertical axis having no requirements for wind direction is maximized. Of course, the rotating arms 31 in the blade assembly 3 can be spirally arranged on the outer side of the rotating rod 2 along the axis of the rotating rod 2, but this arrangement cannot maximize the advantage of the vertical axis. In some embodiments, a connecting rod is connected to one end of the rotating arm 31 in each blade assembly 3 away from the rotating rod 2, and the connecting rod is detachably connected between adjacent rotating arms 31, thereby enhancing the linkage of the rotating arms 31 and improving the stability of the blade assembly 3.

[0037] Each wind drive mechanism may include one or more blade assemblies 3, and the multiple blade assemblies 3 may include two, three or more groups. By increasing the number of blade assemblies 3 in the wind drive mechanism, the rotation speed of a single rotating rod is further increased, the mechanical energy superimposed on the total rotating rod is further increased, and the maximum rated power generation efficiency of the wind power generation device is further increased.

[0038] In this embodiment, the blade 32 may be a curved surface structure such as a curved blade, so that the curved surface blade 32 can sense wind from more directions. Preferably, this embodiment adopts a blade 32 with a hemispherical structure, that is, the blade 32 includes a blade body 321, a windward cavity 322 is arranged inside the blade body 321, a windward port 323 is arranged on one side of the windward cavity 322 of the blade body 321, and a side of the blade body 321 away from the windward port 323 is a curved surface. When the wind blows into the windward cavity 322 from the windward port 323, the windward cavity 322 can make part of the wind pressure stay in the windward cavity 322 because it is a chamber structure. The wind continues to blow into the windward cavity 322, and the force of the wind acting on the inner wall of the windward cavity 322 is superimposed on the force generated by the wind pressure, which drives the blade 32 to rotate, so that even in the case of very low wind speed, the present embodiment can drive the blade 32 to rotate due to the superposition of wind force. In this embodiment, the side of the blade body 321 away from the windward opening 323 is a curved surface, which can be a semi-ellipsoidal, hemispherical or other curved surface shape. The curved surface reduces the influence of wind pressure, reduces the resistance of the non-windward surface, and improves the efficiency of wind energy utilization.

[0039] A further optimized solution is that the stacked wind power generation device also includes a monitoring and control component, which includes a wind speed monitor 5 for monitoring wind speed, and the wind speed monitor 5 is signal-connected to a central processing unit; the blade 32 is slidably connected to the rotating arm 31, and the blade 32 is driven to slide along the rotating arm 31 by a first drive component; the central processing unit is signal-connected to the first drive component; the blade 32 includes at least a first position and a second position; when the blade 32 is in the first position, the distance between the blade 32 and the axis of the rotating rod 2 is a first distance; when the blade 32 is in the second position, the distance between the blade 32 and the axis of the rotating rod 2 is a second distance; the first distance is smaller than the second distance, and the central controller controls the operation of the first drive component according to the wind speed information monitored by the wind speed monitor 5, so that the blade 32 switches between the first position and the second position.

[0040] In this embodiment, the wind speed is monitored in real time by the wind speed monitor 5 and the monitored wind speed information signal is transmitted to the central processor, and the central processor controls the operation of the first drive component according to the received real-time wind speed. When the monitored real-time wind speed is less than the set first wind speed, the central controller controls the operation of the first drive component, and the blade 32 switches from the first position to the second position, that is, the distance between the blade 32 and the axis of the rotating rod 2 becomes larger. When the wind force remains unchanged, the torque of the blade 32 on the rotating rod 2 becomes larger, and the blade 32 is easier to rotate, which realizes the increase of the torque of the blade 32 at low wind speed, improves the wind energy capture efficiency, and increases the blade speed, thereby increasing the power generation and improving the power generation efficiency.

[0041] When the monitored real-time wind speed is greater than the set second wind speed, the central controller controls the operation of the first drive assembly, and the blade 32 switches from the second position to the first position, that is, the distance between the blade 32 and the axis of the rotating rod 2 becomes smaller. When the wind force remains unchanged, the torque of the blade 32 on the rotating rod 2 becomes smaller, preventing the rotating rod 2 from rotating too high due to excessive wind speed, resulting in damage to the generator, blades, rotating rod 2 and other components, thereby improving the safety of the stacked wind power generation device. In this embodiment, the first position and the second position are relative, which does not mean that the blade 32 only has the first position and the second position. The first position and the second position can be two relative positions of the blade 32 relative to the axis of the rotating rod 2, and there are multiple positions such as the third position and the fourth position between the two positions.

[0042] In this embodiment, the first driving component can be driven by a cylinder, a hydraulic cylinder, a lead screw-nut, etc. Preferably, the rotating arm 31 is distributed along the radial direction of the rotating rod 2, and the first driving component is a cylinder, the fixed end of the cylinder is fixedly connected to the rotating rod 2, and the telescopic end of the cylinder is detachably connected to the blade 32. The blade 32 is driven by the cylinder to move along the rotating arm 31, so that the blade 32 can be switched between the first position and the second position, and the blade 32 can be stopped at any position on the moving path.

[0043] Further optimization scheme, the rotating arm 31 in this embodiment includes three fixed rods 311 arranged in a triangle, the three fixed rods 311 are all distributed along the radial direction of the rotating rod 2, and the three fixed rods 311 are arranged in parallel. The three fixed rods 311 are detachably connected at both ends, and the three fixed rods 311 are distributed separately on the moving path of the blade 32. The blade 32 is detachably connected with a fixed frame 312, and the fixed frame 312 is slidably connected to the three fixed rods 311, that is, the fixed frame 312 can slide along the three fixed rods 311, and the sliding interval is the moving path of the blade 32. The fixed frame 312 is detachably connected to the first drive assembly. In this embodiment, the fixed frame 312 is detachably connected to the telescopic end of the cylinder. In this embodiment, the blade 32 slides along the rotating arm 31 through the fixed frame 312.

[0044] Further optimization scheme, the support frame 1 is detachably connected with a brake assembly 6, and the brake assembly 6 is arranged on the outer circumference of the rotating rod 2; the central controller controls the operation of the brake assembly 6 according to the wind speed information monitored by the wind speed monitor 5, and adjusts the rotation speed of the rotating rod 2. When the real-time wind speed monitored is greater than the set third wind speed, the central controller controls the operation of the first drive assembly, and the blade 32 switches from other positions to the third position, and the third position is the minimum limit position that the blade 32 can move to, that is, the distance between the blade 32 and the axis of the rotating rod 2 is the minimum. The central controller controls the operation of the brake assembly 6 to switch the rotating rod 2 to a stationary state, to prevent the rotating rod 2 from rotating too high due to excessive wind speed, resulting in damage to the generator, blades, rotating rod 2 and other components, thereby improving the safety of the stacked wind power generation device. When the real-time wind speed monitored is less than the set third wind speed, but greater than the set second wind speed, the rotation speed of the rotating rod 2 is regulated by the brake assembly 6, so that the rotation speed of the rotating rod 2 is reduced, to prevent the rotating rod 2 from rotating too high due to excessive wind speed, which damages the equipment, and maximizes the use of wind energy. When the equipment needs to be repaired, the central controller controls the brake assembly 6 to operate, so that the rotating rod 2 switches to a stationary state to prevent the blades 32, the rotating arm 31 and other components from causing harm to the staff. When the stacked wind power generation device is working normally, the central controller controls the brake assembly 6 to be in a standby state, that is, the brake assembly 6 does not brake the rotating rod 2, and the rotating rod 2 is in a rotating state.

[0045] In this embodiment, the brake assembly 6 includes a brake disc 61, which is arranged on the outer circumference of the rotating rod 2. A hydraulic cylinder 62 is arranged on the side of the brake disc 61 away from the rotating rod 2. The hydraulic cylinder 62 is fixedly connected to the support frame 1. The brake disc 61 is controlled by the hydraulic cylinder 62 to approach or move away from the rotating rod 2. When the brake disc 61 contacts the rotating rod 2, a squeezing force is generated between the two, thereby increasing the friction between the brake disc 61 and the rotating rod 2, so that the rotating rod 2 stops rotating. Preferably, two brake discs 61 are provided and symmetrically arranged on both sides of the rotating rod 2 to increase the friction between the brake disc 61 and the rotating rod 2, thereby improving the braking performance of the brake assembly 6.

[0046] In this embodiment, any two upper and lower adjacent rotating rods 2 can be connected by a coupling, so that the adjacent rotating rods can rotate synchronously and transmit torque. Preferably, any two upper and lower adjacent rotating rods 2 are detachably connected with a telescopic joint 7, and the telescopic joint 7 includes a sliding rod 71 and a first connecting member 76 and a second connecting member 72 that are detachably connected to the two upper and lower adjacent rotating rods 2, respectively. The first connecting member 76 and the second connecting member 72 are provided with corresponding sliding cavities, and the two ends of the sliding rod 71 are respectively arranged in the two sliding cavities. The outer side of the telescopic rod is provided with an anti-skid rib 73 arranged along the axis of the rotating rod 2, and the inner wall of the sliding cavity is provided with an anti-skid groove that matches the anti-skid rib 73, and the anti-skid ribs 73 are engaged with the anti-skid ribs 73. The two ends of the sliding rod 71 are provided with a limited portion to ensure that the sliding rod 71 can only slide in the two sliding cavities, but the sliding rod 71 cannot be separated from the two sliding cavities.

[0047] When the telescopic joint 7 is working, the sliding rod 71 can slide in the two sliding cavities, so that the distance between the first connecting member 76 and the second connecting member 72 becomes longer or shorter, thereby adapting to the distance between the two adjacent rotating rods 2. Compared with the coupling, the telescopic joint in this embodiment can adapt to different distances between the two rotating rods 2, ensuring that the two rotating rods 2 can be connected. At the same time, in this embodiment, due to the presence of the anti-skid ribs 73 and the anti-skid grooves, and the anti-skid ribs 73 are arranged along the axis of the rotating rod 2, the sliding rod 71 is prevented from rotating relative to the first connecting member 76 or the second connecting member 72, ensuring the transmission of the force of the two adjacent rotating rods, so that the two rotating rods can rotate synchronously.

[0048] Further optimization scheme, a rotating block 74 is arranged between the telescopic joint 7 and the rotating rod 2; one side of the rotating block 74 is rotatably connected with a third connecting member 75, and the rotation axis of the rotating block 74 and the third connecting member 75 is the first axis, and the third connecting member 75 is detachably connected to the adjacent rotating rod 2; the other side of the rotating block 74 is rotatably connected to the telescopic joint 7, and the rotation axis of the rotating block 74 and the telescopic joint 7 is the second axis, and the first axis, the second axis and the axis of the rotating rod 2 are mutually perpendicular. In this embodiment, rotating blocks 74 are arranged at both ends of the telescopic joint 7, and the third connecting member 75 is arranged between the rotating block 74 and the rotating rod 2. The telescopic joint 7, the rotating block 74 and the third connecting member 75 form a universal telescopic joint, and the rotating block 74 and the third connecting member 75 can rotate relative to the first axis, and the rotating block 74 and the telescopic joint 7 can rotate relative to the second axis. However, since the first axis, the second axis and the axis of the rotating rod 2 are mutually perpendicular, the two rotating rods 2 will not rotate due to the existence of the universal telescopic joint, so as to ensure the transmission of the force of the two adjacent rotating rods above and below, so that the two rotating rods can rotate synchronously. Compared with the telescopic joint 7, the universal telescopic joint adds two degrees of freedom. Even if the upper and lower rotating rods 2 are not correspondingly arranged, the two degrees of freedom can make up the axial distance between the two rotating rods 2 so that the two rotating rods can rotate synchronously.

[0049] Further optimization scheme, the support frame 1 includes a column 11, a bearing seat 12 and a crossbeam 13; more than three columns 11 are provided, and the columns 11 are arranged on the outer circumference of the wind drive mechanism; the upper and lower ends of the rotating rod 2 are detachably connected with the bearing seat 12, and a bearing 15 is arranged between the bearing seat 12 and the rotating rod 2; the crossbeam 13 is detachably connected between the column 11 and the bearing seat 12, and the crossbeam 13 is distributed along the radial direction of the rotating rod 2. The main frame is formed by the column 11 and the crossbeam 13, and the bearing 15 and the bearing seat 12 are arranged between the main frame and the rotating rod 2. In this embodiment, the main frame formed by the column 11 and the crossbeam 13 supports the rotating rod 2, and the bearing 15 ensures that the rotating rod 2 can rotate. At the same time, the two sets of bearings in the wind drive mechanism suspend the rotating rod 2, the rotating arm 31, and the blade 32, so that the bearings transmit the gravity of the rotating rod 2, the rotating arm 31, and the blade 32 to the main frame, solving the problem of the bearing capacity of the entire wind power generation blade.

[0050] Preferably, adjacent columns 11 are detachably connected with reinforcing beams 14, which are arranged at the ends of the columns 11. The reinforcing beams 14 strengthen the strength of the main frame formed by the columns 11 and the cross beams 13, further ensuring the stability of the wind drive mechanism.

[0051] In this embodiment, the upper and lower support frames 1 are arranged relatively, and the columns 11 inside the upper and lower groups of support frames 1 are arranged correspondingly, and the upper and lower corresponding columns 11 are connected by bolts and nuts to ensure the stability between the columns 11. A lightning rod 9 is detachably connected to the uppermost support frame 1 to prevent lightning from damaging the entire power generation device. The wind speed monitor 5 is detachably connected to the uppermost support frame 1. Of course, the wind speed monitor 5 can also be set on any layer of the support frame 1, or a wind speed monitor 5 is set on each layer of the support frame 1.

[0052] In a further optimized solution, the number of the columns 11 in the support frame 1 is set to be more than 3, and may be 4, 5, 6, or 7. When the number of stacked wind-driven mechanisms increases, the number of the columns 11 in the support frame 1 also needs to be increased to ensure the strength of each layer of the support frame 1.
