Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a dual-effect vertical axis micro wind generator coupled to a large wind farm. Background Technology

[0002] A dual-effect vertical axis micro wind turbine is a device that converts wind energy into electricity. Its core feature is that it can generate electricity efficiently in low wind speed environments. The working principle of the dual-effect vertical axis micro wind turbine is based on the wind driving the blades to rotate, which in turn drives the generator to generate electricity.

[0003] For example, Chinese patent CN119957414A (A Universal Wind-Gathering Ground-Mounted Vertical Axis Micro-Wind Generator Based on Venturi Effect): includes a main component, including a support, a chamber at the end of the support, a turbine blade at the end of the chamber, and a fan blade array arranged on the outer wall of the turbine blade; an adjustment component at the end of the turbine blade, including a wind power transition channel, an inner partition inside the wind power transition channel, and a Venturi tube at the end of the wind power transition channel; a fan is arranged on the inner wall of the Venturi tube, and control components and connecting components are also arranged on the inner wall of the fan; through the design of the wind power transition channel and the Venturi tube, wind from any direction can be captured and accelerated; a monitoring component is set to detect the fan speed; when the fan speed exceeds a preset threshold, i.e., the threshold at which the turbine blade may be damaged, the speed of the turbine blade and the fan blade is slowed down by electromagnetic braking to avoid damage to the generator when the external wind force is large.

[0004] However, existing vertical axis micro wind turbines require opening the casing door for internal generator maintenance. The door opening angle is limited, and the open door can obstruct the arms of maintenance personnel, making maintenance inconvenient. Furthermore, the locking structure is prone to damage, making maintenance difficult and costly. Therefore, this does not meet the current requirements. To address this, we propose a dual-effect vertical axis micro wind turbine coupled with a large wind farm. Utility Model Content

[0005] The purpose of this invention is to provide a dual-effect vertical axis micro wind generator coupled to a large wind farm, in order to solve the problems mentioned in the background art. In the case of existing vertical axis micro wind generators, the chassis is opened through a door for internal generator body maintenance. However, the opening angle of the door is limited, and the open door will obstruct the arms of the maintenance personnel during maintenance, resulting in inconvenience. Furthermore, the locking structure is easily damaged, making maintenance difficult and costly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-effect vertical axis micro wind generator coupled to a large wind farm, comprising: a power generation body, characterized in that: a crossbeam is provided on the outside of the power generation body, and multiple power generation bodies are provided; a frame is provided at one end of the crossbeam; a wind turbine blade is provided at the top of the frame; the power generation body includes a turbine and a first connecting seat, and the first connecting seat is located at the top of the turbine; a second connecting seat is provided at the bottom of the turbine; blades are provided on the outside of the turbine; connecting frames are fixed between the blades and the first and second connecting seats by external bolts; a housing is provided below the second connecting seat; a door is provided at the front end of the housing; a connecting component is provided at one corner of the door; and the door rotates with the housing through the connecting component; a column is provided at the lower end of the housing.

[0007] Preferably, the connecting assembly includes a positioning rod that passes through the door and the door rotates along the positioning rod.

[0008] Preferably, one end of the positioning rod is provided with a limiting plate, and one end of the limiting plate is provided with a threaded post, which is threadedly connected to the chassis.

[0009] Preferably, the connecting assembly further includes an anti-fall plate, one end surface of which is provided with a threaded rod, and the other end surface of the positioning rod is provided with a threaded groove, and the threaded rod and the threaded groove are threadedly connected.

[0010] Preferably, a stabilizing groove is provided on one side of the upper surface of the door, and an installation groove is provided on one side of the upper surface of the chassis.

[0011] Preferably, a stabilizing plate is provided inside the mounting groove, a rotating groove is provided at one end of the stabilizing plate and the rotating groove passes through the stabilizing plate, a rotating shaft is provided inside the rotating groove, and the two ends of the rotating shaft are welded and fixed to the inner walls of the two sides of the mounting groove, and the stabilizing plate rotates through the rotating groove and the rotating shaft, and a support base is provided on the lower surface of the other end of the stabilizing plate.

[0012] Preferably, the second connecting seat is fixed to the third connecting seat by external bolts, and the lower end of the third connecting seat is fixed to the connecting flange by external bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a connecting component at the corner of the box door. The box door rotates along the connecting component, so the box door will rotate downwards and will not block the opening of the chassis. This allows personnel to have a large range of inspection when the generator installed inside the chassis is being repaired. It is not easy for the box door to obstruct the inspection, and it is also easy to disassemble the generator, which improves convenience and safety. When closing the box door, the stabilizer plate is rotated so that the end of the stabilizer plate with the support seat rotates into the stabilizer slot. The stabilizer plate is inserted into the stabilizer slot to limit the box door and prevent it from rotating open. It is simple and convenient. It solves the problems of the existing vertical axis micro wind generator chassis, which have limited opening angle when the box door is opened to inspect the generator body inside. During the inspection, the open box door will block the arms of the maintenance personnel, which will cause inconvenience to the inspection. In addition, the locking structure is easy to be damaged, which is not convenient to repair and has high maintenance costs.

[0015] (2) By setting a threaded post at one end of the limiting plate, the positioning rod is fixed to the chassis through the threaded post and the positioning rod passes through the door. Then the anti-fall plate is connected to the threaded groove through the threaded rod to limit the door and prevent it from falling. The detachable connection component is easier to replace the door and improves the convenience of disassembly and replacement compared to the existing hinge.

[0016] (3) By connecting multiple power generation entities with crossbeams, and having multiple crossbeams arranged in a layered manner around the frame matrix, it can effectively utilize the 1-3m / s micro-wind resources and wind energy at different heights that traditional wind turbines cannot utilize, thus improving the wind energy utilization rate of the wind farm, significantly increasing the annual power generation of the wind farm, and enhancing the stability and reliability of power generation. The unique dual working mode and vertical axis design of the dual-effect vertical axis micro wind turbine make it more adaptable to changes in wind direction and wind speed. Combined with the real-time monitoring and adjustment of the intelligent control system, it can continuously and stably generate electricity under various meteorological conditions. At the same time, the matrix arrangement and backup power generation system design effectively reduce the risk of power generation interruption caused by the failure of a single device and improve the reliability of power generation of the entire wind farm.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a dual-effect vertical axis micro wind generator coupled to a large wind farm, comprising: a power generation body 24, characterized in that: a crossbeam 25 is provided on the outside of the power generation body 24, and multiple power generation bodies 24 are provided, a frame 26 is provided at one end of the crossbeam 25, and a wind turbine plate 27 is provided at the top of the frame 26. The power generation body 24 adopts a vertical axis design and is based on the original large wind turbine frame 26. The crossbeam 25 is erected 5 meters below the wind turbine plate 27, generally around 45 meters. The power generation body 24 is suspended by the crossbeam 25 and tightened by steel cables, which serve as flexible supports for the power generation body 24. The connection between the steel cables and the crossbeam 25 is connected by bearings, thereby ensuring that the crossbeam 25 and the power generation body 24 rotate together. Compared with traditional horizontal axis generators, it has stronger adaptability to wind direction changes, does not require a complex wind-adapting device, and can operate continuously and stably in complex airflow environments of wind farms;

[0025] When multiple power generation units 24 are arranged in a matrix, the support frame 26 of the large wind turbine is the center, and the power generation units 24 are arranged in a fan shape extending outwards. Within a space range of 10 to 40 meters, they are arranged in layers according to the wind speed characteristics and airflow distribution at different heights. In this space, the wind speed is above 3 m / s, which is suitable for the power generation units 24 to operate in a high-efficiency power generation mode. The number of power generation units 24 arranged in this area is relatively large, forming a dense power generation layer. Along the radial direction of the fan shape, the spacing between adjacent power generation units 24 gradually increases from the center to the edge, with a spacing of 3-5 units near the center. The distance between the edge areas is 8-10 meters to ensure that the power generation systems do not interfere with each other and can make full use of the space. The lower edge of the bottom power generation main body 24 is more than 10 meters above the ground to avoid affecting ground operations. Through the fan-shaped layered arrangement centered on the large wind turbine support 26, the matrix distribution of the power generation main body 24 and the large wind turbine can achieve three-dimensional complementarity in space, making full use of the remaining wind energy in the wake of the large wind turbine, while avoiding mutual airflow interference. At different height levels, the power generation system and the large wind turbine work together to achieve comprehensive development of wind energy resources in the wind field space.

[0026] The generator body 24 includes a turbine 1 and a first connecting seat 4, with the first connecting seat 4 located at the top of the turbine 1. A second connecting seat 5 is provided at the bottom of the turbine 1. Blades 2 are provided on the outside of the turbine 1. Connecting brackets 3 are fixed between the blades 2 and the first connecting seat 4 and the second connecting seat 5 by external bolts. A third connecting seat 6 is fixed to the second connecting seat 5 by external bolts. A connecting flange 7 is fixed to the lower end of the third connecting seat 6 by external bolts. The connecting flange 7 is connected to the output end of the generator, and the generator is installed inside the casing.

[0027] Below the second connecting seat 5 is a housing 8. The front end of the housing 8 has a door 9. A connecting component 10 is located at one corner of the door 9, and the door 9 rotates with the housing 8 via the connecting component 10. A column 11 is located at the lower end of the housing 8. The connecting component 10 includes a positioning rod 15, which passes through the door 9 and rotates along the positioning rod 15. One end of the positioning rod 15 has a limit plate 16, and one end of the limit plate 16 has a threaded post 17, which is threadedly connected to the housing 8. The connecting component 10 also includes an anti-fall plate 18, one end of which has a threaded rod 19, and the other end of the positioning rod 15 has a threaded groove 20. The threaded rod 19 and the threaded groove 20 are connected... The positioning rod 15 is fixed to the chassis 8 via the threaded post 17 and passes through the door 9. The anti-fall plate 18 is threadedly connected to the threaded groove 20 via the threaded rod 19 to limit the door 9 and prevent it from falling. The door 9 rotates along the positioning rod 15. By rotating around the positioning rod 15, the door 9 will rotate downwards and will not block the opening of the chassis 8. This allows personnel to have a large range of access when inspecting the generator installed inside the chassis 8, and it is not easy to be obstructed by the door 9. It also facilitates the disassembly of the generator, improving convenience and safety. In addition, the detachable connection component 10 makes it easier to replace the door 9 compared to the existing hinge, improving the convenience of disassembly and replacement.

[0028] A stabilizing slot 12 is provided on one upper surface of the door 9, and a mounting slot 13 is provided on one upper surface of the chassis 8. A stabilizing plate 14 is provided inside the mounting slot 13. A rotating slot 21 is provided at one end of the stabilizing plate 14, and the rotating slot 21 passes through the stabilizing plate 14. A rotating shaft 22 is provided inside the rotating slot 21, and both ends of the rotating shaft 22 are welded and fixed to the inner walls of the two sides of the mounting slot 13, respectively. The stabilizing plate 14 rotates through the rotating slot 21 and the rotating shaft 22. A support base 23 is provided on the lower surface of the other end of the stabilizing plate 14. When the door 9 is closed, it rotates upward. The door 9 is moved to seal the opening of the chassis 8. Then, the stabilizing plate 14 is rotated so that one end of the stabilizing plate 14 with the support base 23 rotates into the stabilizing slot 12, and the lower surface of the support base 23 contacts the upper surface of the stabilizing slot 12, ensuring that the stabilizing plate 14 is horizontal and not tilted. The door 9 is limited by the stabilizing plate 14 being inserted into the stabilizing slot 12, preventing it from being rotated open. When opening the door, simply lift the stabilizing plate 14 up and down to rotate it and separate it from the stabilizing slot 12, and then the door 9 can be rotated open. It is simple and convenient.
