Power connecting device capable of conveniently disassembling queue-shaped horizontal wind turbines in frame

Abstract

The invention provides a power connecting device which facilitates disassembly and maintenance of a queue-shaped horizontal wind turbine in a frame, and a long-term root cause which puzzles large-scale application of horizontal wind turbine power generation is that horizontal wind turbine blades cannot expand unlimitedly as traditional vertical three-blade fan blades. Even if the efficiency of converting wind power into electric energy is extremely high under the condition of the same size, the wind power and the electric energy cannot be effectively applied to the society. According to the invention, a plurality of horizontal wind turbines are stacked through a frame to form a queue through a specific power connecting device, and the queue is organically connected to a generator to generate electric energy.

Description

Technical fields:

[0001] This invention provides a power connection device for conveniently disassembling a horizontally arranged wind turbine within a frame. This device enables the replacement and repair of individual damaged components without affecting the overall operation of the power generation system. This invention belongs to the field of wind power generation machinery and devices. Background technology:

[0002] This invention provides a power connection device for conveniently disassembling horizontal wind turbines arranged in a frame. A fundamental reason that has long hindered the large-scale application of horizontal wind turbine power generation is that the blades of horizontal wind turbines cannot expand indefinitely like those of traditional vertical three-bladed wind turbines, thus limiting their practical application. Even with extremely high efficiency in converting wind power into electricity under the same size conditions, this technology cannot be effectively utilized. This invention provides a device that uses a specific power connection device to organically connect multiple horizontal wind turbines, arranged in a frame, to a generator to produce electricity. Summary of the Invention:

[0003] This invention provides a power connection device for conveniently disassembling a horizontal wind turbine in a frame, characterized in that: in a modular horizontal wind turbine with multiple standardized dimensions in a frame, the power connection device is connected to a generator to generate electrical energy, and the replacement and maintenance of faulty mechanical parts can be achieved without affecting the operation of the generator.

[0004] In one alternative embodiment, the power connection device, which facilitates the disassembly of the horizontally arranged wind turbines in the frame, is equipped with multiple sealed vertical chain transmission devices. Each vertical chain is connected to a gear set, and each gear is connected to one side of a horizontally arranged wind turbine. The bottom of the vertical chain is connected to the main shaft of the generator gear set and is equipped with a tensioning and clutch device. This ensures that if a vertical chain fails and needs replacement or maintenance, it does not affect the operation of the wind turbine units on other vertical chains, which then drive the generator to generate electricity.

[0005] In one optional embodiment, the power connection device for conveniently disassembling the horizontally arranged wind turbines in the frame includes a set of intelligent electric transmission devices on both sides of the gear shaft connecting the horizontal wind turbine shaft on each vertical chain. This electric transmission helps reduce the wind resistance and wind energy conversion rate of the horizontal wind turbine when encountering destructive winds, while also reducing the operational risk and failure rate of the wind turbine, and providing sufficient assurance for the stable operation of the generator under severe wind conditions. In another optional embodiment, the power connection device for conveniently disassembling the horizontally arranged wind turbines in the frame is equipped with a set of wind detection and intelligent control transmission devices. This allows the wind force sensor to transmit wind force values, and the intelligent controller to adjust the wind turbine speed conversion ratio by controlling the electric transmission in the power connection device according to the wind force, thereby ensuring the stability of the generator unit operation and reducing the wind resistance and failure rate of the wind turbine when encountering destructive storms. In one alternative embodiment, the power connection device for facilitating the disassembly of a horizontally arranged wind turbine in a frame is equipped with a set of pneumatic brake devices. These devices are located on one side of the detachable wind turbine shaft and the vertical chain gear and electric transmission shaft, respectively. When a wind turbine needs to be disassembled for maintenance, the shaft associated with the wind turbine shaft to be disassembled is braked simultaneously to stop its operation, facilitating the disengagement of the crosslinking device from the shaft connection.

[0006] In one alternative embodiment, the power connection device that facilitates the disassembly of the horizontal wind turbines in the frame is equipped with a fixed bracket with an electro-hydraulic lifting device at each position on the vertical chain drive shaft where the wind turbine can be assembled. The detachable wind turbine is first placed on the fixed bracket of the wind turbine shaft. The bracket is equipped with a hydraulic lifting device, and the bracket is hydraulically lifted to realize the installation or disassembly of the wind turbine.

[0007] In one alternative embodiment, in the power connection device that facilitates the disassembly of the horizontal wind turbine in the frame, a set of roller supports is provided on the fixed hydraulic upgrade bracket, and the end of the hydraulic lifting bracket is supported by two rollers. When loading and unloading the wind turbine, the wind turbine shaft sits on the roller support, and the wind turbine shaft can be finely adjusted so that the mortise and tenon joint of the wind turbine shaft is accurately aligned after entering the slot.

[0008] In one alternative embodiment, the power connection device that facilitates the disassembly of the horizontal wind turbine in the frame has a column connected to the vertical chain gear shaft at one end, which is connected to the wind turbine shaft via a tenon-and-mortise joint structure. The columnar shaft connection part of the joint device is formed by the slot head and the male and female tenons being spliced ​​together. During assembly, the wind turbine shaft connection part is inserted into the slot by a hydraulic lifting bracket on the roller support. By finely adjusting the position of the wind turbine shaft, the male and female tenons of the columnar shaft connection part are fully fitted, thereby enabling the wind turbine shaft to drive the vertical chain gear to rotate. During maintenance, a brake device is used to fix the shaft connected to the slot, and the detachable wind turbine shaft is disassembled from the tenon joint and removed from the slot by the hydraulic lifting bracket to achieve disassembly.

[0009] In one alternative embodiment, the power connection device that facilitates the disassembly of the horizontal wind turbines arranged in a frame includes a gear set with a main shaft. Each set of vertical chains connected to the horizontal wind turbines on the frame is respectively connected to the gears on the main shaft. The main shaft is connected to the generator through the gear set. As the wind turbine group on the frame operates, the generator eventually generates electricity through this power transmission device.

[0010] Those skilled in the art can make various modifications and variations to this invention without departing from the spirit and scope of this invention. However, if the modifications and variations of this invention fall within the scope of the claims of this invention and their equivalents, this invention also intends to include such modifications and variations.
