Description

technical field

The utility model relates to the technical field of wind power generation, in particular to a support rod structure of a wind turbine in a wind turbine.

background technique

A wind turbine is an electrical system that converts wind power into mechanical work. The mechanical work drives the rotor, which spins and eventually outputs alternating current. Wind turbines generally consist of wind turbines, generators, pitch controls, towers, speed-limiting safety mechanisms and energy storage; The principle of operation of wind turbines is relatively simple: the wind turbine rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind turbine shaft, and the generator is driven and rotated by the wind turbine shaft to generate electricity; In the broadest sense, wind energy is also a type of solar energy, so it can also be said that the wind turbine is a type of thermal generator that uses the sun as a heat source and the atmosphere as a working medium.

The current wind turbines mainly use horizontal and vertical shaft generators, the vertical shaft generators can better adapt to the environment and are more suitable for small and medium-sized wind turbines; however, current vertical shaft generators can easily damage the internal mechanical structure in extreme weather conditions or when the wind exceeds the work intensity. In addition, the current vertical shaft generators mostly use fixed structures, and the wind resistance is difficult to regulate, and the load on the generator when the wind is too strong is difficult to reduce, so it is easy to damage the equipment in case of accidents, what not only affects the power generation, but also increases the additional maintenance costs.

Content of the utility model

The purpose of the utility model is to eliminate the deficiencies of the prior art and to propose a support bar structure of a wind wheel in a wind turbine.

• Eine Tragstangenstruktur eines Windrads in einer Windkraftanlage, die einen Sockel umfasst, dass der Sockel eine an der Oberseite fest montierten Tragstange aufweist, wobei die Tragstange an der Oberseite eine durchs Lager fest montierte Verbindungsscheibe aufweist, wobei die Verbindungsscheibe eine an der Seite montierte Windkraftumwandlungsvorrichtung aufweist, wobei die Windkraftumwandlungsvorrichtung an der Seite eine Blattvorrichtung aufweist, wobei die Tragstange an der Oberseite eine Pufferrutsche aufweist, wobei die Pufferrutsche in den Seitenwänden eine Anzahl von symmetrischen Einrastschlitzen aufweist, wobei die Pufferrutsche einen Teleskopring aufweist, der beweglich an der Unterseite der Pufferrutsche angebracht ist, wobei die Verbindungsscheibe einen an der Unterseite fest montierten Befestigungsring aufweist, wobei der Befestigungsring einen an der Unterseite fest montierten Einstellblock aufweist.

In order to achieve the above purpose, the utility model adopts the following technical solution:

• A support rod structure of a wind turbine in a wind turbine, comprising a base, that the base has a support rod fixedly mounted on the top, the support rod on the top having a connecting disk fixedly mounted through the bearing, the connecting disk having a wind power conversion device mounted on the side, the wind power conversion device having a blade device on the side, the support bar having a buffer chute at the top, the buffer chute having a number of symmetrical latching slots in the side walls, the buffer chute having a telescopic ring movably attached to the underside of the buffer chute, the connecting disk having a mounting ring fixedly mounted on the underside, the mounting ring having an adjustment block fixedly mounted on the underside.

Preferably, the adjustment block has a hollow structure on the bottom and sides, the adjustment block having two sets of inner slides and two sets of outer slides snapped together on the inside, and the inner slides and the outer slides have a compression spring fixed between them is mounted.

Preferably, the outer slides and the compression springs are both fixedly mounted with end stops on their sides, the adjustment block being provided with end slides on its sides adapted to the end stops, the adjustment block being connected to the inner slides and outer slides via the end slides and the end stops .

Preferably, the two sets of inner slides have a slanted construction at the bottom mating side, and the size of the slanted opening at the bottom of the two sets of inner slides is adapted to the width of the telescopic ring.

Preferably, the width of the adjustment block is matched to the width of the buffer chute, the sides of both sets of outer slides adjacent to the buffer chute are rounded, and the edges of the latching slot are also rounded.

1. 1. Wenn die Windstärke für den Betrieb der Windkraftanlage geeignet ist, steuert Steuerzentrale den Teleskopring, sich nach oben zu bewegen, wodurch die beiden Sätze von Innenschiebern dazu gebracht werden, sich in Richtung der beiden Seiten des Teleskoprings zu trennen, wobei der Druck auf die Außenschieber ausgeübt wird, indem die zusammengedrückte Druckfeder komprimiert wird, was bewirkt, dass die Außenschieber an der Innenseite des Einrastschlitzes einrasten, so dass die Verbindungsscheibe einen stabilen statischen Zustand beibehält, wodurch sichergestellt wird, dass die von der Blattvorrichtung empfangene Windkraft stabil ist und der stabile Betrieb des Stromerzeugungsmechanismus gewährleistet wird.
2. 2. Bei zu starkem Wind erfasst die Steuerzentrale, dass die Geschwindigkeit der Übertragungsstange zu hoch ist, was die Sicherheit des internen Mechanismus beeinträchtigen kann, steuert die Steuerzentrale so, dass der Teleskopring nach unten schrumpft und die beiden Sätze von Innenschiebern anliegen. Die Schiebkraft der Innenschieber auf den Außenschiebern wird durch die Druckfeder verringert, und die Außenschieber können sich relativ zum abgerundeten Ecken am Rand des Einrastschlitzes bewegen, um das Einrasten der Innenschieber vom Einrastschlitz zu lösen, so dass sich der Einstellblock im Pufferschlitz drehen kann. Gleichzeitig entsteht durch das Schieben der Druckfeder auf den Außenschieber eine Reibung zwischen dem Außenschieber und der Innenwand der Pufferrutsche, die dafür sorgt, dass sich der Einstellblock auf der Innenseite der Pufferrutsche langsam weiterdreht. Das heißt, die Verbindungsscheibe treibt die Windkraftumwandlungsvorrichtung und die Blattvorrichtung an, sich in der Umgebung mit starkem Wind langsam um die Tragstange mit dem Wind effektiv zu drehen und einen Teil des Windwiderstands und der Spannung zu entfernen und die Drehzahl der Übertragungsstange zu verringern. Dadurch wird eine reibungslose Funktion des Mechanismus gewährleistet und die Lebensdauer des Mechanismus effektiv verlängert.

The advantages of the utility model over the prior art are:

1. 1. When the wind strength is suitable for the operation of the wind turbine, the control center controls the telescopic ring to move up, causing the two sets of inner sliders to separate toward the two sides of the telescopic ring, with the pressure on the Outer slider is exerted by compressing the compressed compression spring, which causes the outer sliders to snap to the inside of the detent slot, so that the connecting disc maintains a stable static state, thereby ensuring that the wind force received by the blade device is stable and the stable Operation of the power generation mechanism is guaranteed.
2. 2. When the wind is too strong, the control center will sense that the transmission rod speed is too high, which may affect the safety of the internal mechanism, the control center will control the telescopic ring to shrink down, and the two sets of inner sliders will abut. The pushing force of the inner sliders on the outer sliders is reduced by the compression spring, and the outer sliders can move relative to the rounded corners on the edge of the locking slot to release the locking of the inner sliders from the locking slot, allowing the adjustment block to rotate in the buffer slot. At the same time, pushing the compression spring onto the outer slide creates friction between the outer slide and the inner wall of the buffer chute, which ensures that the adjustment block on the inside of the buffer chute continues to turn slowly. That is, the connecting disk drives the wind power conversion device and the blade device to rotate slowly around the support rod with the wind in the strong wind environment, effectively removing part of the wind resistance and tension and reducing the rotation speed of the transmission rod. This ensures smooth operation of the mechanism and effectively prolongs the life of the mechanism.
