Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, and in particular to a wind power generation erection device. Background Technology

[0002] Wind energy is a clean and pollution-free renewable energy source. Wind power generation refers to the process of converting the kinetic energy of wind into electrical energy. Its principle is based on the fact that the kinetic energy of wind is converted into mechanical energy through the wind turbine blades, and then converted into electrical energy by the generator.

[0003] In the prior art, such as Chinese Publication No. CN203488315U, this utility model discloses a wind turbine frame, including a pole, with a pole base rotatably connected to the lower end of the pole. Two identical and symmetrical reinforced concrete seats are provided at both ends of the pole base, with U-shaped grooves on the two seats. Two rotating shafts are symmetrically welded to both sides of the pole base, and the shafts engage with the U-shaped grooves of the two reinforced concrete seats to form a rotatable connection. A positioning block is welded to the bottom of the pole base, and a positioning seat matching the positioning block is provided on the ground between the two reinforced concrete seats. The positioning block is fixed to the positioning seat by bolts. Several crossbars are symmetrically provided on both sides of the upper end of the pole, and several turbine bases are symmetrically provided on the crossbars. This utility model has a simple and stable structure, is easy to install and maintain, and can install multiple wind turbines. Through the rotatable pole and the tail rudder vertically fixed to the pole, the wind turbine frame's air intake direction can rotate with the wind direction to align with the incoming wind, thereby improving the wind energy utilization rate of the wind turbine.

[0004] While the above-mentioned solutions have the advantages mentioned above, their disadvantages include the lack of a structure for bending the wind turbine installation poles, which prevents the device from improving its flexibility through bending. The device may also be unable to pass through tunnels, bridges, or urban underpasses due to the excessive size of the tower, thus limiting its practicality and applicability. Furthermore, the lack of a structure to dampen and buffer the vibrations and swaying experienced by the device during installation and transportation limits its durability and service life. Utility Model Content

[0005] The purpose of this utility model is to provide a wind power generation erection device. This utility model designs a structure for bending the installation pole of the wind power device, which can improve the flexibility of the device through bending. It avoids the situation where the device cannot pass through tunnels, bridges or urban underpasses due to the size limitation of the tower. This improves the practicality and universality of the device. The design also includes a structure to dampen the vibration and sway of the device during installation and transportation, thereby improving the durability and service life of the device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wind power generation erection device, comprising:

[0007] The lower rod body, having two fixing plates fixedly disposed on its outer surface, further includes:

[0008] Two first connecting plates are rotatably connected to the outer surfaces of the two fixed plates, and a rotating block is rotatably connected to the opposite surfaces of the two first connecting plates. An electro-hydraulic rod is fixedly installed on the outer surface of the lower rod, and the output end of the electro-hydraulic rod is fixedly connected to the outer surface of the rotating block. A second connecting plate is rotatably connected to the outer surfaces of the two first connecting plates, and a rotating arm is rotatably connected to the outer surfaces of the two second connecting plates. The rotating arm is rotatably connected to the fixed plate, and an upper rod body is fixedly installed on the outer surface of the rotating arm. When the electro-hydraulic rod retracts, it drives the rotating block to move, thereby driving the two first connecting plates to rotate on the surface of the fixed plate, driving the second connecting plates on both sides to rotate, and driving the rotating arm to rotate around the fixed plate. The rotating arm drives the upper rod body to rotate and bend relative to the lower rod body.

[0009] Preferably, mounting plates are fixedly provided on the opposing surfaces of the upper rod and the lower rod. Multiple second bolts are threaded onto the inner surfaces of the two mounting plates, and second nuts are threaded onto the outer surfaces of the multiple second bolts. The lower rod and the upper rod are fastened together by the two mounting plates in conjunction with the second bolts and the second nuts.

[0010] Preferably, a first damper is fixedly provided on the outer surface of each of the two first connecting plates, and the two first dampers are rotatably connected to the two second connecting plates respectively. The two first dampers provided on the surface of the first connecting plates on both sides reduce the speed at which the swing arm and the upper rod body rotate and bend in the downward direction of the rod body.

[0011] Preferably, a plurality of second dampers are fixedly provided on the outer surface of the lower rod body, and a protective plate is fixedly provided on the outer surface of the plurality of second dampers. The protective plate provides buffer protection for the upper rod body, and the extension and retraction of the plurality of second dampers reduces the vibration and shaking of the lower rod body and the upper rod body during installation and transportation.

[0012] Preferably, each of the multiple second damping outer surfaces is fixedly provided with a buffer spring, and the outer surfaces of the multiple buffer springs are fixedly connected to the outer surface of the protective plate. The multiple buffer springs undergo elastic deformation to buffer the vibration and shaking of the lower rod and the upper rod during installation and transportation.

[0013] Preferably, a power generation mechanism is fixedly installed on the top outer surface of the upper rod body, and multiple fan blades are fixedly installed at the input end of the power generation mechanism. The power generation mechanism, together with the multiple fan blades, converts wind energy into electrical energy.

[0014] Preferably, a stabilizing seat is fixedly provided on the bottom outer surface of the lower rod, and a base plate is fixedly provided on the bottom outer surface of the stabilizing seat. The stabilizing seat and the base plate work together to provide stable support for the lower rod.

[0015] Preferably, the inner surface of the base plate is threaded with a plurality of first nuts, and the outer surface of each of the plurality of first nuts is threaded with a first bolt, thereby securing the base plate in place by means of the first nuts and the first bolts.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the retraction of the electro-hydraulic rod drives the rotating block to move, which in turn drives the two first connecting plates to rotate on the surface of the fixed plate, drives the second connecting plates on both sides to rotate, and drives the rotating arm to rotate around the fixed plate. The rotating arm drives the upper rod to rotate and bend relative to the lower rod. The bending of the upper rod improves the flexibility of the device. The two first dampers set on the surface of the first connecting plates on both sides reduce the speed of the rotating arm and the upper rod rotating and bending towards the lower rod, thereby improving the stability of the device. The two mounting plates, together with the second bolt and the second nut, securely connect the lower rod and the upper rod. The first nut and the first bolt securely install the base plate.

[0018] 2. In this utility model, the upper rod is bent to contact the surface of the protective plate, and multiple second damping extensions reduce the vibration and sway of the lower and upper rods during installation and transportation. At the same time, multiple buffer springs undergo elastic deformation to buffer the vibration and sway of the lower and upper rods during installation and transportation. Attached Figure Description

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as Figures 1 to 4 As shown, this utility model provides a wind power generation erection device, including a lower pole body 1. Two fixed plates 15 are fixedly installed on the outer surface of the lower pole body 1. Two first connecting plates 11 are rotatably connected to the outer surfaces of the two fixed plates 15 respectively. Rotating blocks 10 are rotatably connected to the opposite surfaces of the two first connecting plates 11. An electro-hydraulic rod 9 is fixedly installed on the outer surface of the lower pole body 1. The output end of the electro-hydraulic rod 9 is fixedly connected to the outer surface of the rotating block 10. A second connecting plate 13 is rotatably connected to the outer surfaces of the two first connecting plates 11. A rotating arm 14 is rotatably connected to the outer surfaces of the two second connecting plates 13. The rotating arm 14 is rotatably connected to the fixed plates 15. An upper pole body 2 is fixedly installed on the outer surface of the rotating arm 14. When the electro-hydraulic rod 9 retracts, it drives the rotating block 10 to move, thereby driving the two first connecting plates 11 to rotate on the surface of the fixed plates 15, driving the second connecting plates 13 on both sides to rotate, thereby driving the rotating arm 14 to rotate around the fixed plates 15. The rotating arm 14 drives the upper pole body 2 to rotate and bend relative to the lower pole body 1.

[0028] Furthermore, such as Figures 1 to 4 As shown, mounting plates 16 are fixedly installed on the opposite surfaces of the upper rod body 2 and the lower rod body 1. Multiple second bolts 17 are threadedly connected to the inner surfaces of the two mounting plates 16, and second nuts 18 are threadedly connected to the outer surfaces of the multiple second bolts 17. The lower rod body 1 and the upper rod body 2 are fastened together by the two mounting plates 16 in conjunction with the second bolts 17 and the second nuts 18.

[0029] Furthermore, such as Figures 1 to 4 As shown, the outer surfaces of the two first connecting plates 11 are fixedly provided with first dampers 12. The two first dampers 12 are rotatably connected to the two second connecting plates 13 respectively. The two first dampers 12 provided on the surfaces of the first connecting plates 11 on both sides reduce the speed at which the rotating arm 14 and the upper rod 2 rotate and bend in the direction of the lower rod 1.

[0030] Furthermore, such as Figures 1 to 4As shown, multiple second dampers 19 are fixedly installed on the outer surface of the lower rod 1, and protective plates 21 are fixedly installed on the outer surface of the multiple second dampers 19. The protective plates 21 provide buffer protection for the upper rod 2, and the extension and retraction of the multiple second dampers 19 reduce the vibration and shaking of the lower rod 1 and the upper rod 2 during installation and transportation.

[0031] Furthermore, such as Figures 1 to 4 As shown, multiple second dampers 19 are fixedly provided with buffer springs 20 on their outer surfaces. The outer surfaces of multiple buffer springs 20 are fixedly connected to the outer surface of the protective plate 21. The multiple buffer springs 20 undergo elastic deformation to buffer the vibration and shaking of the lower rod 1 and the upper rod 2 during installation and transportation.

[0032] Furthermore, such as Figures 1 to 4 As shown, a power generation mechanism 3 is fixedly installed on the top outer surface of the upper pole body 2. Multiple fan blades 4 are fixedly installed at the input end of the power generation mechanism 3. The power generation mechanism 3, together with the multiple fan blades 4, converts wind energy into electrical energy.

[0033] Furthermore, such as Figures 1 to 4 As shown, a stabilizing seat 5 is fixedly installed on the bottom outer surface of the lower rod 1, and a base plate 6 is fixedly installed on the bottom outer surface of the stabilizing seat 5. The stabilizing seat 5 and the base plate 6 provide stable support for the lower rod 1.

[0034] Furthermore, such as Figures 1 to 4 As shown, the inner surface of the base plate 6 is threaded with multiple first nuts 7, and the outer surface of each of the multiple first nuts 7 is threaded with a first bolt 8. The base plate 6 is securely installed by means of the first nuts 7 and the first bolts 8.

[0035] Working principle: When the electro-hydraulic rod 9 is opened, it retracts, causing the rotating block 10 to move. This, in turn, causes the two first connecting plates 11 to rotate on the surface of the fixed plate 15, which in turn causes the second connecting plates 13 on both sides to rotate. This, in turn, causes the rotating arm 14 to rotate around the fixed plate 15. The rotating arm 14 causes the upper rod 2 to rotate and bend relative to the lower rod 1. The bending of the upper rod 2 improves the flexibility of the device. The two first dampers 12 on the surfaces of the first connecting plates 11 on both sides reduce the speed at which the rotating arm 14 and the upper rod 2 rotate and bend towards the lower rod 1. To improve the stability of the device, the lower rod 1 and the upper rod 2 are fastened together by two mounting plates 16 with the second bolt 17 and the second nut 18. The base plate 6 is securely installed by the first nut 7 and the first bolt 8. The upper rod 2 is bent to contact the surface of the protective plate 21. Multiple second dampers 19 extend and retract to reduce the vibration and sway of the lower rod 1 and the upper rod 2 during installation and transportation. At the same time, multiple buffer springs 20 undergo elastic deformation to buffer the vibration and sway of the lower rod 1 and the upper rod 2 during installation and transportation.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
