DETAILED DESCRIPTION

[0031] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] REFERENCE Figures 1-9 The embodiment provides a stacked wind power generation device, which comprises a plurality of groups of wind driving mechanisms, and all the wind driving mechanisms are arranged in a stacked mode; the wind driving mechanism comprises a support frame 1, the support frame 1 is rotationally connected with a rotating rod 2, the rotating rod 2 is detachably connected with a blade assembly 3 on the radially outer side, and the blade assembly 3 is used for converting wind energy into mechanical energy for driving the rotating rod 2 to rotate; any two adjacent support frames 1 in the up-down direction are detachably connected, and any two adjacent rotating rods 2 in the up-down direction are detachably connected; all the rotating rods 2 are coaxially arranged, and the rotating rod 2 at the end is transmissionally connected with a generator 4.

[0033] The embodiment is provided with several groups of wind driving mechanisms, and the upper and lower adjacent rotating rods 2 are detachably connected to form a total rotating rod. The blade assemblies 3 in each group of wind driving mechanisms can capture the wind energy in nature 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 thrust generated by all the blade assemblies is superimposed on the total rotating rod, so as to improve the thrust and rotating speed of the total rotating rod, and further superimpose the mechanical energy acting on the rotating rod, so that the generator set 4 converts the superimposed mechanical energy into electrical energy, thereby improving the power generation efficiency of the wind power generation device. In the later period, the rotating speed of the total rotating rod, i.e. the mechanical energy superimposed on the total rotating rod, can be further improved by increasing the number of wind driving mechanisms, so as to further improve the rated power generation efficiency of the wind power generation device without replacing new devices, but only by superimposing new wind driving mechanisms, thereby reducing the cost.

[0034] In the embodiment, the speed increaser 8 is arranged between the rotating rod 2 and the generator 4. The speed increaser 8 is a gear set speed change mechanism, which converts the low-speed rotating motion of the rotating rod 2 into high-speed rotating motion and transmits the high-speed rotating motion to the generator 4, so as to ensure that the generator 4 can normally generate electricity. 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 shaft position of the turbine blade is sleeved outside the rotating rod 2, and the turbine blade is detachably connected with the rotating rod 2. The blade assembly 3 can capture the wind energy in nature and convert the wind energy into mechanical energy for driving 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 outside the rotating rod 2, and the blade assembly 3 includes several rotating arms 31 which are detachably connected with the rotating rod 2, and the rotating arms 31 are connected with blades 32. In the embodiment, the wind energy is captured by the blades 32, that is, the wind with a certain wind speed acts on the blades 32, the blades 32 and the rotating arms 31 start to rotate under the action of the wind force, drive the rotating rod 2 to rotate, and the blade assembly 3 converts the wind energy into mechanical energy for driving the rotating rod 2 to rotate. Compared with the integrated blade assembly 3, the blade assembly 3 in the embodiment is convenient for maintenance and repair of the blade assembly 3 in the later period, and the number of blades 32 and rotating arms 31 can be increased or decreased to control the mechanical energy of the rotating rod 2 in each group of wind driving mechanisms in the later period.

[0036] In the embodiment, the number of the blades 32 in the blade assembly 3 is at least three, that is, the number of the blades 32 in the blade assembly 3 can be multiple, four, five, six, or seven. The rotating rod 2 is arranged perpendicularly to the ground, that is, the vertical axis is arranged; 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 annularly on the outer side of the rotating rod 2 in the circumferential direction, and the rotating arms 31 in the same blade assembly 3 are 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 at least one or more blades 32 can be affected by the wind force regardless of the wind direction, and the advantage of the vertical axis without requirement for the wind direction is maximally exerted. 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 the advantage of the vertical axis cannot be maximally exerted in this arrangement. In some embodiments, the end of each rotating arm 31 in each blade assembly 3 away from the rotating rod 2 is connected with a connecting rod, and the connecting rod is detachably connected between the adjacent rotating arms 31, so as to enhance the linkage of the rotating arms 31 and improve the stability of the blade assembly 3.

[0037] Each wind driving mechanism can include one or more blade assemblies 3, and the multiple blade assemblies 3 include two, three or more blade assemblies 3. By increasing the number of the blade assemblies 3 in the wind driving mechanism, the rotating speed of the single rotating rod is further improved, the mechanical energy stacked on the total rotating rod is further improved, and the rated power generation efficiency of the wind power generation device is further improved.

[0038] In the embodiment, the blade 32 can be selected as a curved surface structure such as a curved blade, so as to perceive more directions of the wind through the curved surface blade 32. Preferably, the blade 32 in the embodiment adopts a semi-spherical structure, that is, the blade 32 includes a blade body 321, the blade body 321 is internally provided with a windward cavity 322, the blade body 321 is provided with a windward opening 323 on one side of the windward cavity 322, and the side of the blade body 321 away from the windward opening 323 is a curved surface. When the wind blows into the windward cavity 322 from the windward opening 323, the windward cavity 322 can make part of the wind pressure stay in the windward cavity 322 due to the chamber structure, the wind continuously blows into the windward cavity 322, the force of the wind acting on the inner wall of the windward cavity 322 is superimposed with the force generated by the wind pressure, so as to push the blade 32 to rotate, thereby enabling the embodiment to drive the blade 32 to rotate due to the superposition of the wind force even in the case of low wind speed. In the embodiment, the side of the blade body 321 away from the windward opening 323 is a curved surface, which can be a semi-elliptical spherical surface, a semi-spherical surface or other curved surface shape, so as to reduce the influence of the wind pressure, reduce the resistance of the non-windward surface, and improve the wind energy utilization efficiency.

[0039] Further optimization scheme, the stacked wind power generation device further comprises a monitoring control assembly, the monitoring control assembly comprises a wind speed monitor 5 for monitoring the wind speed, and the wind speed monitor 5 is signal connected with a central processing unit; the blade 32 is slidably connected with the rotating arm 31, and the blade 32 is driven to slide along the rotating arm 31 by a first driving assembly; the central processing unit is signal connected with the first driving assembly; the blade 32 comprises 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 processing unit controls the first driving assembly to operate according to the wind speed information monitored by the wind speed monitor 5, so that the blade 32 is switched between the first position and the second position.

[0040] In the embodiment, the wind speed monitor 5 is used to monitor the wind speed in real time and transmit the monitored wind speed information to the central processing unit, and the central processing unit controls the first driving assembly to operate 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 processing unit controls the first driving assembly to operate, and the blade 32 is switched 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. In the case that the wind force remains unchanged, the moment of the blade 32 on the rotating rod 2 becomes larger, and the blade 32 is more easily rotated, so that the moment of the blade 32 is increased at low wind speed, the wind energy capturing efficiency is improved, the blade rotating speed is increased, and thus the power generation amount is increased and the power generation efficiency is improved.

[0041] When the monitored real-time wind speed is greater than the set second wind speed, the central processing unit controls the first driving assembly to operate, and the blade 32 is switched 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. In the case that the wind force remains unchanged, the moment of the blade 32 on the rotating rod 2 becomes smaller, so that the safety of the stacked wind power generation device is improved. In the embodiment, the first position and the second position are relative, and it is not said that the blade 32 only exists in 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 a third position, a fourth position and a plurality of positions are further provided between the two positions.

[0042] In the embodiment, the first driving assembly can be a cylinder drive, a hydraulic cylinder drive, a screw-nut drive, or the like. Preferably, the rotating arms 31 are distributed along the radial direction of the rotating shaft 2, and the first driving assembly is a cylinder. The fixed end of the cylinder is fixedly connected to the rotating shaft 2, and the telescopic end of the cylinder is detachably connected to the blades 32. The blades 32 are driven to move along the rotating arms 31 by the cylinder, so as to switch the blades 32 between the first position and the second position, and the blades 32 can be stopped at any position on the moving path.

[0043] Further optimization, the rotating arms 31 in the embodiment include three fixed rods 311 arranged in a triangular shape. The three fixed rods 311 are distributed along the radial direction of the rotating shaft 2, and are arranged in parallel. The first end and the second end of the three fixed rods 311 are detachably connected, and the three fixed rods 311 are distributed on the moving path of the blades 32. The blades 32 are detachably connected to a fixed frame 312, and the fixed frame 312 is slidably connected to the three fixed rods 311, i.e., the fixed frame 312 can slide along the three fixed rods 311, and the sliding interval is the moving path of the blades 32. The fixed frame 312 is detachably connected to the first driving assembly. In the embodiment, the fixed frame 312 is detachably connected to the telescopic end of the cylinder. The blades 32 are driven to slide along the rotating arms 31 by the fixed frame 312.

[0044] Further optimization, the support frame 1 is detachably connected to a brake assembly 6, and the brake assembly 6 is arranged on the outer side of the rotating shaft 2 in the circumferential direction. The central processing unit controls the operation of the brake assembly 6 according to the wind speed information monitored by the wind speed monitor 5, so as to control the rotating speed of the rotating shaft 2. When the monitored real-time wind speed is greater than the third set wind speed, the central processing unit controls the first driving assembly to operate, and the blades 32 are switched from other positions to the third position. The third position is the minimum limit position to which the blades 32 can move, i.e., the distance between the blades 32 and the axis of the rotating shaft 2 is the smallest. The central processing unit controls the brake assembly 6 to operate, so as to switch the rotating shaft 2 to a stationary state, thereby preventing the rotating speed of the rotating shaft 2 from being too high due to the excessively high wind speed, and preventing the damage of the generator, the blades, the rotating shaft 2, and the like, so as to improve the safety of the stacked wind power generation device. When the monitored real-time wind speed is less than the third set wind speed but greater than the second set wind speed, the rotating speed of the rotating shaft 2 is reduced by the brake assembly 6, so as to prevent the rotating speed of the rotating shaft 2 from being too high due to the excessively high wind speed, and to maximize the use of wind energy while preventing the damage of the equipment. When the equipment needs to be repaired, the central processing unit controls the brake assembly 6 to operate, so as to switch the rotating shaft 2 to a stationary state, thereby preventing the blades 32, the rotating arms 31, and the like from harming the workers. When the stacked wind power generation device is in normal operation, the central processing unit controls the brake assembly 6 to be in a standby state, i.e., the brake assembly 6 does not brake the rotating shaft 2, and the rotating shaft 2 is in a rotating state.

[0045] In the embodiment, the brake assembly 6 comprises a brake disc 61 which is arranged on the outer side of the rotating rod 2 in the circumferential direction, and the side of the brake disc 61 away from the rotating rod 2 is provided with a hydraulic cylinder 62 which is fixedly connected with the support frame 1, and the brake disc 61 is controlled to approach or move away from the rotating rod 2 through the hydraulic cylinder 62, when the brake disc 61 contacts the rotating rod 2, extrusion force is generated between the two, so as to increase the friction between the brake disc 61 and the rotating rod 2, so as to stop the rotating rod 2 from rotating. Preferably, two brake discs 61 are arranged symmetrically on the two sides of the rotating rod 2, so as to increase the friction between the brake disc 61 and the rotating rod 2, and further improve the braking performance of the brake assembly 6.

[0046] In the embodiment, the two adjacent rotating rods 2 can be connected through a shaft coupling, so that the adjacent rotating rods can rotate synchronously and transmit torque. Preferably, the two adjacent rotating rods 2 are detachably connected with an expansion joint 7, the expansion joint 7 comprises a sliding rod 71 and a first connecting piece 76 and a second connecting piece 72 which are detachably connected with the two adjacent rotating rods 2 respectively, the first connecting piece 76 and the second connecting piece 72 are provided with corresponding sliding cavities, the two ends of the sliding rod 71 are arranged in the two sliding cavities respectively, the outer side of the sliding rod 71 is provided with anti-skid ribs 73 which are arranged along the axis of the rotating rod 2, the inner wall of the sliding cavity is provided with anti-skid grooves which are matched with the anti-skid ribs 73, and the anti-skid ribs 73 are clamped with the anti-skid grooves. The two ends of the sliding rod 71 are provided with limiting portions, so 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] In the working process of the expansion joint 7, the distance between the first connecting piece 76 and the second connecting piece 72 can be lengthened or shortened due to the sliding of the sliding rod 71 in the two sliding cavities, so as to adapt to the distance between the two adjacent rotating rods 2. Compared with the shaft coupling, the expansion joint in the embodiment can adapt to different distances between the two rotating rods 2, so as to ensure that the two rotating rods 2 can be connected. At the same time, due to the existence 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 rotation of the sliding rod 71 relative to the first connecting piece 76 or the second connecting piece 72 is prevented, the force transmission between the two adjacent rotating rods is ensured, and the two rotating rods can rotate synchronously.

[0048] Further optimization scheme, the 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 the third connecting piece 75, and the rotating axes of the rotating block 74 and the third connecting piece 75 are the first axis; the third connecting piece 75 is detachably connected with the adjacent rotating rod 2; the other side of the rotating block 74 is rotatably connected with the telescopic joint 7, and the rotating axes of the rotating block 74 and the telescopic joint 7 are the second axis; the first axis, the second axis and the axis of the rotating rod 2 are perpendicular to each other. In the embodiment, the rotating block 74 is arranged at both ends of the telescopic joint 7, the third connecting piece 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 piece 75 form a universal telescopic joint, the rotating block 74 and the third connecting piece 75 can rotate relative to the first axis, the rotating block 74 and the telescopic joint 7 can rotate relative to the second axis, but because the first axis, the second axis and the axis of the rotating rod 2 are perpendicular to each other, the two rotating rods 2 will not rotate due to the existence of the universal telescopic joint, the force transmission between the adjacent two rotating rods is ensured, and the two rotating rods can rotate synchronously. Relative to the telescopic joint 7, the universal telescopic joint increases two degrees of freedom, so that the distance between the axes of the two rotating rods 2 can be compensated through the two degrees of freedom even if the two rotating rods 2 are not correspondingly arranged, and the two rotating rods can rotate synchronously.

[0049] Further optimization scheme, the support frame 1 includes the column 11, the bearing seat 12 and the cross beam 13; the column 11 is provided with three or more than three, and the column 11 is arranged on the outer side of the wind driving mechanism in the circumferential direction; the upper and lower ends of the rotating rod 2 are detachably connected with the bearing seat 12, and the bearing 15 is arranged between the bearing seat 12 and the rotating rod 2; the cross beam 13 is detachably connected between the column 11 and the bearing seat 12, and the cross beam 13 is distributed along the radial direction of the rotating rod 2. The main frame is formed by the column 11 and the cross beam 13, and the bearing 15 and the bearing seat 12 are arranged between the main frame and the rotating rod 2. In the embodiment, the main frame formed by the column 11 and the cross beam 13 supports the rotating rod 2, and the rotation of the rotating rod 2 is ensured through the bearing 15. At the same time, the two groups of bearings in the wind driving 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, thereby solving the problem of bearing force of the entire wind power generation blade.

[0050] Preferably, the reinforcing beam 14 is detachably connected between the adjacent columns 11, and the reinforcing beam 14 is arranged at the end of the column 11. The strength of the main frame formed by the column 11 and the cross beam 13 is strengthened through the reinforcing beam 14, thereby further ensuring the stability of the wind driving mechanism.

[0051] In the embodiment, the upper and lower arranged support frames 1 are oppositely arranged, and the columns 11 in the two groups of support frames 1 are correspondingly arranged, the correspondingly arranged columns 11 are connected through bolts-nuts, so as to ensure the stability between the columns 11. The lightning rod 9 is detachably connected to the uppermost support frame 1, so as to prevent lightning from damaging the whole power generation device. The wind speed monitor 5 is detachably connected to the uppermost support frame 1, and of course, the wind speed monitor 5 can also be arranged on any layer of support frame 1, or one wind speed monitor 5 is arranged on each layer of support frame 1.

[0052] Further optimization scheme, the number of columns 11 in the support frame 1 is set to be more than 3, 4, 5, 6 or 7.
