When 1 vibration of wire is stronger, wire 1 drives the damper amplitude of oscillation, it is great to assist the tup to slide and keep away from steel strand wires 8 under violent swing, the tensile extension spring of the supplementary tup of motion becomes long, then the extension spring will assist the tup to draw close steel strand wires 8 under the effect of its natural contraction power, this process makes the damping effect of damper strengthen and increase along with 1 vibration of wire, weaken and reduce along with 1 vibration of wire, it is better to realize automatically regulated and anti-vibration effect, owing to adopt flexible guide rail, make the home range of supplementary tup further increase, the damping effect is better.
The invention concept of the application is as follows:
when the wire vibration amplitude is less, the absorbed energy of the damper is less, when the wire vibration energy is great, the damper changes the gravity center position of the hammer head through the spring, the purpose of increasing the absorbed energy is realized, and meanwhile, the vibration sensor and the wireless remote transmission system which are installed on the damper are utilized to monitor the wire vibration condition.
Technical contribution of the present application:
take real-time supervision's self-interacting damper, it includes fastener, connector, lays the solar cell panel on the connector, sets up vibration sensor and wireless teletransmission system on the connector, steel strand wires, main tup, supplementary tup, connecting spring.
The purpose of the invention is as follows:
the invention aims to provide a self-adjusting damper, and aims to solve the problems that a traditional damper in the prior art is poor in vibration absorption and vibration prevention effects, and cannot monitor the vibration of a lead.
Description of the technical solution:
the utility model provides a take real-time supervision's self-interacting damper, be in the same place through fastener 2 and 1 rigid connection of wire, fastener 2 is in the same place with 4 rigid connection of connector, lay the solar cell panel on the connector 4 for supply power for the damper, be provided with vibration sensor and wireless teletransmission system 3 on the connector 4, rigid connection steel strand wires 8 on the connector 4, the main tup in both sides is connected to steel strand wires 8, main tup passes through the supplementary tup of spring coupling.
When the breeze vibration amplitude of the wire is small, the main hammer head is tightly connected with the auxiliary hammer head through the spring, the vibration energy of the wire is absorbed through the steel strand swinging hammer head, when the breeze vibration amplitude is large, the swinging amplitude of the hammer head is correspondingly increased, the spring extends, the auxiliary hammer head is far away from the main hammer head, the spring is involved in swinging to further absorb the energy, the larger the breeze vibration amplitude of the wire is, the longer the spring extends, the more the absorbed energy is, and therefore the self-adjusting function is achieved.
Because the connecting body 3 is rigidly fixed with the lead 1, the vibration condition monitored by the vibration sensor and the wireless remote transmission system arranged on the connecting body 3 is that the vibration condition of the lead, the vibration sensor and the wireless remote transmission system are powered by the solar cell panel laid on the connecting body 4.
