DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described in detail below.

[0021] Embodiment 1

[0022] This utility model provides a wind power-specific busbar oscillation damper, such as... Figures 1 to 5 As shown, the device includes a fixed plate 1, a cylinder 2 fixedly connected to one end of the fixed plate 1, a spring 3 fixedly connected inside the cylinder 2, a slider 4 fixedly connected to one end of the spring 3, the slider 4 being movably connected inside the cylinder 2, a ball head rod 5 rotatably connected to one end of the slider 4, the ball head rod 5 being composed of a ball and a cylinder, the ball being rotatably connected to one end of the slider 4, a support bracket 6 fixedly connected to one end of the slider 4 below the ball head rod 5, a polyester pad 7 being glued to the top of the support bracket 6, a busbar trough 8 fixedly connected to one end of the ball head rod 5, a protective sleeve 9 fixedly connected between one end of the cylinder 2 and the side of the busbar trough 8, positioning plates 10 being provided at both the top and bottom of the busbar trough 8, a threaded rod 11 movably connected inside the positioning plates 10, the outer surface of the threaded rod 11 penetrating the interior of the busbar trough 8, and a nut 12 being threadedly connected to the outer surface of the threaded rod 11 at the bottom of the busbar trough 8.

[0023] like Figure 1 and Figure 4 As shown, a fixing block 13 is fixedly connected inside the busbar trough 8, and a spring telescopic rod 14 is fixedly connected inside the fixing block 13. A pressing block 15 is fixedly connected to the movable end of the spring telescopic rod 14. The pressing block 15 is movably connected inside the fixing block 13. Limiting blocks 16 are fixedly connected to both ends of the pressing block 15. The limiting blocks 16 are movably connected to both sides of the fixing block 13. When an object is connected to the busbar trough 8 through the positioning plate 10, the elastic force of the spring telescopic rod 14 can press the object tightly, enhancing the stability of the connection between the busbar trough 8 and the object.

[0024] like Figure 1 and Figure 3 As shown, one end face of the polyester pad 7 is in contact with one end face of the ball head rod 5. The polyester pad 7 can just support the weight of the busbar 8 when it is stationary and does not swing, and when the ball head rod 5 swings, its softness and hardness can allow displacement in all directions, which improves the stability of the busbar 8 and ensures its reliability under various working conditions.

[0025] like Figure 1 and Figure 2 As shown, the inner diameter of the protective sleeve 9 is the same as the inner diameter of the cylinder 2. The protective sleeve 9 is made of rubber, which can prevent dust or impurities from entering the connection between the slider 4 and the ball head rod 5, thus affecting the normal rotation of the ball head rod 5 and improving the reliability of the ball head rod 5.

[0026] like Figure 1 and Figure 4As shown, the rubber pad 17 is attached to the bus duct 8 at the position inside the positioning card plate 10 away from one end of the protective sleeve 9, which can increase the friction when the object is connected to the bus duct 8 through the positioning card plate 10, and can protect the bus duct 8, thereby improving the reliability and durability of the overall connection.

[0027] As shown in Figure 1 and Figure 5 The limiting block 16 is T-shaped, and the size of one end of the limiting block 16 close to the extrusion block 15 is smaller than the size of the other end, which can provide stable support and limit the extrusion block 15, thereby improving the stability of the extrusion block 15.

[0028] Working principle: during actual use, first, the object to be connected is aligned with the bus duct 8, then the object is moved towards the bus duct 8, the object first contacts the extrusion block 15, as the object slowly moves, the object extrudes the extrusion block 15, the extrusion block 15 extrudes the spring telescopic rod 14 to cause the spring telescopic rod 14 to deform, thereby driving the extrusion block 15 to move towards the protective sleeve 9, the movement of the extrusion block 15 drives the limiting block 16 to move synchronously, as the extrusion block 15 moves inward, the object moves, when the object contacts the rubber pad 17, the movement stops, the object is clamped and limited by the positioning card plate 10, then the nut 12 is tightened, at this time, the connection with the object is completed, due to the elastic force of the spring telescopic rod 14, the object can be compressed, and due to the action of the rubber pad 17, the friction between the bus duct 8 and the object is increased, thereby improving the stability of the bus duct 8 connection and avoiding the problem of loose connection caused by long-term use.

[0029] Then, when the bus duct 8 is connected to the object, when the bus duct 8 is in a stationary state without swinging, due to the action of the polyester rubber pad 7, the bus duct 8 weight can be just supported, so that the ball head rod 5 does not displace, thereby improving the stability of the bus duct 8, when the bus duct 8 is in a working state, it will shake, causing the bus duct 8 to extrude the ball head rod 5, the ball head rod 5 extrudes the sliding block 4, and the sliding block 4 extrudes the spring 3 to deform and buffer, which can buffer the force of the bus duct 8, effectively reducing the shaking of the bus duct 8, improving the stability of the bus duct 8, ensuring the reliability of the bus duct 8 under various working conditions, and meeting the long-term stable operation demand under complex working conditions.

[0030] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
