Embodiment

[0016] Example: see figure 1 with figure 2 , in the figure, 1-line card, 2-elastic rod, 3-hammer, 4-connecting plate.

[0017] The anti-vibration hammer made of fiber reinforced composite material includes a line card 1 and a hammer head 3. There are two hammer heads 3, which are arranged at both ends of the elastic rod 2. The middle part of the elastic rod 2 is provided with a connection with the line card 1. The plate 4 and the connecting plate 4 are composite pultruded plates, the elastic rod 2 is a composite pultruded rod, and the hammer head 3 is a composite body of structural steel and composite material.

[0018] The connection part between the hammer head 3 and the elastic rod 2 is composite material. The connecting part between the hammer head 3 and the elastic rod 2 is structural steel. The hammer head 3 is a structural steel wrapped with a composite material. The composite material is a fiber reinforced composite material.

[0019] When in use, due to the rigi...

Abstract

The invention discloses a fiber reinforced composite material anti-vibration hammer. The shockproof hammer comprises a line card and hammers. There are two hammers which are arranged on two ends of anelastic rod. A middle portion of the elastic rod is provided with a connection board forming an integral structure with the line card. The connection board is a composite material pultrusion sheet material. An elastic rod is a composite material pultrusion bar material. Each hammer is a complex body of structural steel and a composite material. A connection portion of each hammer and the elasticrod is the composite material. The connection portion of each hammer and the elastic rod is the structural steel. Each hammer is the structural steel whose external layer is wrapped with the compositematerial. The composite material is a fiber reinforced composite material. In the invention, through using the fiber reinforced composite material, problems that a capability for an existing vibration hammer to absorb energy of vibration is poor, the vibration hammer is easy to be oxidized, and a corrosion resistance capability is poor are solved; an eddy current is eliminated; and line energy consumption is reduced.

Description

Technical field: [0001] The invention relates to the field of power supply, in particular to a fiber-reinforced composite antivibration hammer. Background technique: [0002] Breeze vibration has a great impact on the safety and life of overhead cables, especially long-span high-voltage transmission conductors. Vibration control of overhead cables under breeze excitation can improve conductor life and prevent disconnection accidents. Vibration control technology is divided into passive control and active control. Due to the requirements of the controller's working position and environment, passive passive control is currently the main method of wire breeze vibration control, which is specifically implemented as a shock-proof hammer. [0003] Existing anti-vibration hammers are mainly made of metal materials, mainly steel; structural forms include steel strand anti-vibration hammers, damping spring anti-vibration hammers and the like. Although the steel anti-vibration hammer...
