The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-2, a kind of novel anti-freeze floating type anti-ice equipment, consists of following several parts:
Comprise the anti-ice cone 1 with endoporus.Anti-ice cone, referring to prior art, can adopt positive wimble structure, back taper structure or positive back taper combining structure.
Comprise electric heating pillar assembly 2.Described electric heating pillar assembly is packed on the endoporus of anti-ice cone.Concrete, the two ends of electric heating pillar assembly are equipped with flange with holes, are threaded connection part and anti-ice cone is connected.Electric heating pillar assembly adopts the existing product on market.Electric heating pillar assembly is by the power connection on wire and offshore platform.
Comprise the guide rail 3 being packed on works pile, electric heating pillar assembly and anti-ice cone movable set are on guide rail.Concrete, under the effect of the external force along guide rail rail length direction, electric heating pillar assembly and anti-ice cone move up and down along guide rail together.
Comprise actuating unit 4, transmission mechanism 5.Actuating unit, transmission mechanism are all installed on offshore platform.Described actuating unit consists of motor 41 and double output shaft reducer 42.Motor is selected explosion proof three-phase asynchronous motor, and double output shaft reducer adopts worm gear structure, and motor and reductor can adopt integral structure, can be also the two absolute construction, its structure select the locus of depending on equipment installation.Described transmission mechanism consists of the two component transmission mechanisms that are located at actuating unit both sides, and every component transmission mechanism includes slip clutch 51, power transmission shaft 52, is packed in the cylinder 53 on power transmission shaft and is wrapped in the wire rope 54 on cylinder.Concrete, power transmission shaft supports by being located at the bracing strut at two ends, and bracing strut can be processed voluntarily, also can adopt bearing and the bearing support combined mechanism of standard, and cylinder is located between two bracing struts.The two ends of slip clutch are connected with an output shaft and the power transmission shaft of reducer by shaft coupling respectively.The free end of wire rope connects anti-ice cone.Concrete, two side positions that are positioned at guide rail in the upper surface of anti-ice cone weld respectively two wire rope holders 11, and every wire rope is being divided into two strands near free-ended position, and two stocks are not connected respectively with two wire rope holders of homonymy.
Operating principle of the present utility model:
Adopt above-mentioned anti-ice equipment, can realize anti-ice cone along being fixed on the guide rail servo-actuated lifting with seawater tidal undulation on works pile.Its principle is: anti-ice cone is subject to the acting in conjunction (pulling force=gravity-buoyancy) of gravity, buoyancy and lineoutofservice signal pull on sea level.The pulling force of wire rope drives transmission mechanism to produce by actuating unit.Be specially: the rotation of driven by motor double output shaft reducer, double output shaft reducer drives the slip clutch of both sides to rotate by shaft coupling, and the slip clutch of both sides drives respective rollers to rotate by shaft coupling, and cylinder is wound around or release wire rope.Regulate the output torque of slip clutch, make the pulling force of wire rope antagonism ice piton body keep constant, this moment of torsion is the setting moment of torsion of slip clutch.After having met thus ice raft extruding cone assembly, generation bending fractures, produces the optimum opening ice, and makes cone assembly and sea level remain on the position of opening ice of setting.When sea level is moved on flood tide, because the effect of buoyancy increases, torque is now less than the setpoint torque of slip clutch, slip clutch engages, drive drum rotating, wire rope is wound around on cylinder, and wire rope pulls the desired location that moves to anti-ice cone and sea level in anti-ice cone; When sea level moves down with ebb tide, because buoyancy reduces, gravity increases, moment moment of torsion increase surpasses the setting moment of torsion of slip clutch, anti-ice cone declines owing to skidding, and in the process declining, buoyancy increases gradually, when anti-ice cone drops to the setting moment of torsion position of slip clutch, anti-ice cone is got back to again the optimum position keeping with sea level.Therefore, adopt above-mentioned actuating unit and transmission mechanism, make anti-ice cone and sea level remain at the position that the conical surface is anti-icing, the effect that opens ice is best.Above-mentioned electric heating pillar assembly makes maintenance between anti-ice cone and guide rail slide and not freeze, and has guaranteed that anti-ice cone can fluctuate freely.
