Description

Technical Field

[0001] This utility model relates to the technical field of wind power generation accessories, specifically a vibration damping component for wind power generation equipment. Background Technology

[0002] Wind power generation equipment, as a type of renewable energy generation equipment, works on the principle of using wind power to drive the wind turbine blades to rotate, thereby generating electricity through a series of energy conversion processes. However, in practical applications, wind frequency vibrations are generated during wind power generation. Existing designs use rubber sleeves to mitigate these vibrations. However, these rubber sleeves will crack during long-term use and need to be replaced. But because the broken rubber sleeves are pressed onto the motor body by metal rings, disassembly is difficult, increasing replacement time and the workload of workers.

[0003] Therefore, a vibration damping component for wind power generation equipment is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration damping component for wind power generation equipment, so as to solve the problem mentioned in the background art that the broken rubber sleeve is pressed into the motor body by a metal ring, which makes disassembly difficult, increases replacement time, and increases the labor intensity of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping component for wind power generation equipment, comprising a housing, a base plate fixedly connected to the housing, a plurality of springs connected to the base plate, each spring tightly pressing against a linkage plate, a hydraulic rubber sleeve provided above the linkage plate, the hydraulic rubber sleeve being fixedly connected to an inner metal ring, and the inner metal ring being slidably connected to an inner ring.

[0006] Preferably, the inner metal ring has a positioning pin inside, and a locking rod is provided on one side of the inner metal ring, the locking rod tightly pressing against the inner ring.

[0007] Preferably, the inner ring rod body has a positioning groove, and the positioning pin is slidably connected to the positioning groove.

[0008] Preferably, the outer shell has an inner pressure plate inside and an outer pressure plate outside. The outer pressure plate clamps one side of the hydraulic rubber sleeve, and the inner pressure plate clamps the other side of the hydraulic rubber sleeve.

[0009] Preferably, the inner metal ring is slidably connected to the outer shell, and the inner metal ring is tightly pressed against the linkage plate.

[0010] Preferably, the linkage plate is slidably connected to the outer shell, and the linkage plate is provided with an extension rod that extends to the inner side of the inner pressure plate.

[0011] Preferably, the base plate is threadedly connected to the outer shell, and a positioning post is fixedly connected to the inner side of the base plate, with the positioning post sleeved inside the spring.

[0012] Preferably, the hydraulic rubber sleeve is filled with hydraulic oil.

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

[0014] This invention uses an inner ring to slide and connect an inner metal ring. The inner metal ring, together with a locking rod, tightly presses against the inner ring, allowing the broken hydraulic rubber sleeve to be removed directly by loosening the inner and outer pressure plates during replacement. This avoids forced peeling of the rubber sleeve due to the pressing of the metal ring, thus reducing the difficulty of operation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figures 1-6 The diagram shows a vibration damping component for a wind power generation device, including a housing 1. The housing 1 is fixedly connected to a base plate 2. The base plate 2 is connected to multiple springs 3. Each spring 3 tightly presses against a linkage plate 4. A hydraulic rubber sleeve 5 is provided above the linkage plate 4. The hydraulic rubber sleeve 5 is fixedly connected to an inner metal ring 6. The inner metal ring 6 is slidably connected to an inner ring 7. The hydraulic rubber sleeve 5 is filled with hydraulic oil. When the spring is compressed, it pushes the linkage plate to slide along the inner wall of the housing, and the hydraulic rubber sleeve above the linkage plate is deformed by pressure.

[0029] Furthermore, a positioning pin 601 is provided inside the inner metal ring 6, and a locking rod 602 is provided on one side of the inner metal ring 6. The locking rod 602 tightly presses against the inner ring 7, and the positioning groove provided in the inner metal ring ensures the stability of the connection between the inner metal ring and the inner ring.

[0030] Furthermore, the inner ring 7 rod body is provided with a positioning groove, and the positioning pin 601 slides to connect with the positioning groove to ensure the stability of the inner ring sliding, as well as to facilitate installation and positioning.

[0031] Furthermore, the outer casing 1 is provided with an inner pressure plate 101 inside and an outer pressure plate 102 outside. The outer pressure plate 102 clamps one side of the hydraulic rubber sleeve 5, and the inner pressure plate 101 clamps the other side of the hydraulic rubber sleeve 5. The inner pressure plate inside the outer casing and the outer pressure plate outside the outer casing jointly clamp both sides of the hydraulic rubber sleeve to prevent radial displacement when it is compressed. The extension rod of the linkage plate extends to the inner side of the inner pressure plate to ensure that the inner pressure plate is synchronously stressed when the linkage plate moves, thus maintaining clamping stability.

[0032] Furthermore, the inner metal ring 6 is slidably connected to the outer shell 1, and the inner metal ring 6 is tightly pressed against the linkage plate 4. The inner metal ring slidably connects to the outer shell, ensuring the stability of the hydraulic rubber sleeve sliding up and down.

[0033] Furthermore, the linkage plate 4 is slidably connected to the outer shell 1. The linkage plate 4 is provided with an extension rod 401, which extends to the inner side of the inner pressure plate 101. Through the extension rod of the linkage plate, the hydraulic rubber sleeve is filled with hydraulic oil. When under pressure, the hydraulic oil flows in the sleeve and consumes vibration energy through the liquid viscous resistance, thereby achieving secondary damping and shock absorption.

[0034] Furthermore, the base plate 2 is threadedly connected to the outer shell 1, and the positioning post 201 is fixedly connected to the inner side of the base plate 2. The positioning post 201 is sleeved on the inner side of the spring 3.

[0035] In this solution, the workflow is as follows: When the wind power generation equipment vibrates during operation, the vibration is first transmitted to the inner ring. The inner ring is connected to the hydraulic rubber sleeve through an inner metal ring. The hydraulic rubber sleeve is clamped inside the outer shell by an inner pressure plate and an outer pressure plate. At the same time, a linkage plate works with a spring. When the spring is compressed, it pushes the linkage plate to slide along the inner wall of the outer shell. The hydraulic rubber sleeve above the linkage plate is then deformed by pressure. When replacing, the broken hydraulic rubber sleeve can be directly removed by loosening the inner and outer pressure plates, avoiding forced peeling of the rubber sleeve due to the compression of the metal ring, thus reducing the difficulty of operation.
