Adopt above-mentioned technical scheme, the principle of work for half firm formula connecting device of ocean structure energy quick despatch is as follows:
First modular marine works 6 and second modular marine works 7 operation in ocean, various sea situation can be run into, be subject to load complicated and changeable, but following several load can be reduced to: pressure load, drag load, the synergy of shearing load, flexural load, torque load and this 5 kinds of load or certain several load wherein.
When the first modular marine works 6 and the second modular marine works 7 are subject to the impact move toward one another of wave or ocean current, connecting device is under pressure, the compression of resistance to compression linkage unit 8 elastic medium spring 2 produces restoring force and resists this load, reduce intermodule displacement, keep stablizing between modular marine works.
When the impact that the first modular marine works 6 and the second modular marine works 7 are subject to wave or ocean current is moved dorsad, connecting device under tension, connect cable wire 1 stretching generation pulling force in resistance to compression linkage unit 8 and resist this load, reduce intermodule displacement, keep stablizing between modular marine works.
When the impact that the first modular marine works 6 and the second modular marine works 7 are subject to wave or ocean current produces vertical relative displacement, connecting device is subject to shearing force, connection cable wire 1 stretching in resistance to compression linkage unit 8 produces restoring force and resists this load, reduce intermodule displacement, keep stablizing between modular marine works.
When the impact that the first modular marine works 6 and the second modular marine works 7 are subject to wave or ocean current produces vertical angular transposition, connecting device is subject to moment of flexure, and connection cable wire 1 stretching in the resistance to compression linkage unit 8 of angular transposition opposite side produces restoring force and resists this load; Resistance to compression linkage unit 8 elastic medium spring 2 compression of angular transposition phase the same side produces restoring force and resists this load, and both combineds action reduce intermodule displacement, keeps stablizing between modular marine works.
When the impact that the first modular marine works 6 and the second modular marine works 7 are subject to wave or ocean current produces longitudinal relative torsion displacement, connecting device is subject to moment of torsion, connection cable wire 1 stretching in resistance to compression linkage unit 8 produces restoring force and resists this load, reduce intermodule displacement, keep stablizing between modular marine works.
When the first modular marine works 6 and the second modular marine works 7 be subject to wave or ocean current impact produce displacement, angular transposition or torsional displacement time, connecting device is subject to the synergy comprising pulling force, pressure, shearing, moment of flexure and moment of torsion, resistance to compression linkage unit 8 stretches or compresses generation restoring force and resists this load, reduce intermodule displacement, keep stablizing between modular marine works.Wave and ocean current transfer energy to bindiny mechanism by works, and outside energy, by being out of shape and moving, consumes by spring and cable wire, and kinetic transformation is heat energy, thus ensure the safety of bindiny mechanism and ocean structure.
This connecting device is also applicable to the connection between multiple modular marine works, modular marine works surrounding is arranged this connecting device can realize quick connection between adjacent modular ocean structure and be separated.
