Abstract
The invention relates to a method for reducing swaying or vibration of water-based facilities. The method is used for reducing swaying of the water-based facilities by arranging damping devices thereon. The method for reducing swaying of the water-based facilities can guarantee the water-based facilities stable and protect goods or machines or the water-based facilities from damage by vibration, and can be used for large-scale overwater platforms requiring for stability of the water-based facilities, yachts and the like.
Description
Technical field
The present invention relates to a kind of method that facility waterborne rocks or shakes that reduces.
Background technology
Damper is at building, and automobile uses in the aircraft in a large number, and facility waterborne is not seen for the damping that reduces facility integral body.Facility waterborne often has strongly in the shipment process and rocks, and causes the personage to fall in the entry, and precision optical machinery destroys, and causes a large amount of life, property loss.Be rigidly connected and can realize friction or few vibrations, but cause facility to destroy easily, the cost height, problem such as can't be realized in a lot of places.The method that minimizing facilities waterborne such as existing tension hawser rock the effect of damping is also arranged, but hawser is not special-purpose damping facility, and damping action is little, and damping effect is unreliable, and causes the hawser fracture.
Summary of the invention
At above-mentioned technical problem, the present invention proposes a kind of solution to the problems described above.The present invention is special-purpose damping facility, rocks when reducing facility lade waterborne by the damping damping, and reliable damping effect is arranged.
A kind ofly reduce the method that facility waterborne rocks, be provided with the damping damping unit by facility on the water and reduce facility waterborne and rock.
Described damping damping unit is at least one mass and at least one spring, and described mass links to each other with facility waterborne by described spring.
Described damping damping unit is at least one presstressed reinforcing steel and at least one anchor pile, and described anchor pile links to each other with described facility waterborne by described presstressed reinforcing steel.
Described damping damping unit is for being provided with the tabular member that extends laterally on the water between facility and the water contact portion.
The gravity of the mass of described spring lower end is greater than 0.5 times of facility carrier gravity waterborne.
The prestressing force that described presstressed reinforcing steel applies is greater than 0.5 times of facility carrier gravity waterborne.
The described tabular member that extends laterally is at least one deck, describedly tabularly extend laterally total side that member has to stretch area be S1, the described tabular member that extends laterally is swung in water highly and to be H1, the product value of described S1 and H1 is Fn with the product value of water density again, and the value of described Fn is greater than 0.5 times of facility carrying quality waterborne.
A kind ofly reduce the method that facility waterborne rocks, be provided with the UNICOM duct by facility and water body touching position on the water, described UNICOM duct is level or is arranged vertically.
The volume in described UNICOM duct and the value of water density product are greater than 0.5 times of facility carrying quality waterborne.
Beneficial effect provides facility waterborne stably, prevents that the vibrations of goods or machine or facility waterborne from damaging, and prevents that the personage from hitting the drink.Can be used for requirement facility waterborne large-scale pier stably, yacht etc.

The specific embodiment
As shown in Figure 1, a kind of facility waterborne that spring damping is set, the lower end of described spring links to each other with mass.Produce downforce when goods is transported on the facility waterborne, facility waterborne sinks and vibrations, relaxing of spring when facility waterborne sinks, and tensioned during come-up discharges the damping force opposite with ride motion direction waterborne.
As shown in Figure 2, be provided with the facility waterborne of presstressed reinforcing steel damping; Anchor into stake at described presstressed reinforcing steel; Produce downforce when goods is transported on the facility waterborne, facility waterborne sinks and vibrations, and presstressed reinforcing steel is relaxed state at this moment, and during come-up, presstressed reinforcing steel is tightened by pulling force.Applies prestressing force and also can pass through the ship anchor, and anchor chain applies, namely as shown in Figure 1 in anchor chain 16, ship anchor 17, ship anchor 17 also can contact or anchor in the water-bed portion soil with water-bed face.
As shown in Figure 3, a kind of damping pier: comprise first truss 1; Bearing post 2; First side extending plate 3; Second side extending plate 4; Second truss 5; The 3rd side extending plate 6; Presstressed reinforcing steel 12; Facility 13 waterborne; Stake 14; UNICOM duct 15; Spring 16; Steel concrete counterweight 17.
Described bearing post 2 preferred water droplet tee sections, or the side that the flow path direction that can keep meeting water is set is stretched branch water plate.
Produce the power of come-up when facility waterborne sinks, UNICOM duct 15 power that water generates presses down in the duct when running into facility come-up waterborne forms the damping force opposite with ride motion direction waterborne.
Wherein, when the described UNICOM of water impact duct 15, hydrostatic pressure increases the prevention water impact, changes flow direction, makes current walk around flat roof area.
Further be provided with piston in the preferred described UNICOM duct 15, during the piston motion, the side draining of sinking increases buoyancy, and the side that floats water inlet increases gravity.
When sinking, facility waterborne produces power upwards, first side extending plate 3 during come-up; Second side extending plate 4; The 3rd side extending plate 6 produces the power that presses down, and discharges the damping force opposite with ride motion direction waterborne.
Total side that described first side extending plate 3, second side extending plate 4, the 3rd side extending plate 6 have is stretched area S1, it highly is H1 that described first side extending plate 3, second side extending plate 4, the 3rd side extending plate 6 are swung in water, the product value of described S1 and H1 and the product value of water density are Fn, and the value of described Fn is greater than 0.5 times of facility carrying quality waterborne.
Preferably, the value of described Fn is 1 ~ 2 times that facility waterborne carries quality.
Further, described first side extending plate 3, second side extending plate 4, the 3rd side extending plate 6 are opening-closing structure.
Comprise one of above-mentioned feature person all within protection scope of the present invention.
