Abstract

The invention discloses an anti ice vibration method of above-water platform and relative special device, which comprises: mounting a anti ice vibration of above-water platform in the water near the legs of above-water platform; said anti ice vibration device contains one ice-breaker prick and a vibration insulated damping device between the legs and the ice-breaker prick. With said invention, the ice force load of marine platform can be damped by said device to force on the platform, and via selecting parameters, it can be effectively damped. The invention has simple process, without changing former structure of platform, which can be directly mounted on the former platform. In addition, a sealing device is arranged between the legs and the inner wall of ice-break prick, to avoid seawater eroding inner space, to improve its service life.

Description

The anti-ice method of slight and the specialized equipment of above water platform

Technical field

The present invention relates to the anti-ice method of slight and the specialized equipment of above water platform, particularly relate to and a kind ofly can not change the original design of platform and the effectively anti-ice method of slight and the specialized equipment of the above water platform of vibration damping substantially.

Background technology

The above water platform of cold district (especially platform) can be subjected to the effect of glacial ice, is example with China Bohai Sea, and this effect can cause the vibration of above water platform.When comprising in the frequency spectrum of this effect or more can causing flat-bed steady-state vibration during near free vibration period of structure, accelerate the flat-bed fatigue failure and influence normal life and the work of personnel on the platform, therefore should be as much as possible when construct platform alleviate ice and carry the flat-bed vibration that causes by improving design.The way that has at present is the vibration isolation technique that adopts in the resemble construction, with the certain position below the platform spar deck with under foundation utilize rubber vibration insulating pad to isolate, intercept the high frequency pumping of bottom section.This mode has certain vibration isolating effect, but since structure such as riser pipe can not be cut off, therefore this antivibration mode sometimes difficulty reach ideal effect.Therefore, a kind of platform ice year device that can overcome above-mentioned contradiction will be a kind of technology that has using value of platform antivibration aspect.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can not change the original design of platform and the effectively anti-ice method of slight and the specialized equipment of the above water platform of vibration damping substantially.

For achieving the above object, specialized equipment provided by the present invention is: a kind of anti-ice vibrating device of above water platform, it includes one and is arranged on the outer awl that opens ice of above water platform leg post, and is arranged on the leg post and the vibration isolation and damping device between boring of opening ice.

In practical operation, the described awl that opens ice is arranged near the water surface of above water platform leg post, and promptly horizontal surface is up and down in the tidal level variation range.In addition, described leg post and opening ice is provided with between the conical inner surface in order to prevent the packaging system of marine denudation interior arrangement; This assembling device is water proof rubber or resilient High molecular material.

In the anti-ice vibrating device of above-mentioned above water platform, described vibration isolation and damping device is isolation spring or damper.Specifically, this vibration isolation and damping device is for adopting the steel-wire isolator of rubber encapsulation, and it includes: pedestal, be fixed in the vibration damping steel rope on the pedestal, and the rubber of vibration damping steel rope outer package.

The anti-ice method of slight of above water platform provided by the present invention is: near the anti-ice vibrating device that above-mentioned above water platform is installed the water surface of platform leg post on the water.

The present invention is owing to take above design, and it has the following advantages:

1, behind employing the present invention, because flat-bed opens ice and between awl and the leg post vibration isolation and damping device is set on the water, therefore the suffered ice load of platform will be by acting on the platform structure after the decay of vibration isolation and damping device, by the parameter of suitable selecting arrangement, can reach actv. vibration damping, vibration isolating effect.

2, the invention process is simple, can not change the original design of platform substantially, even can carry out the back on legacy platform the anti-problem of shaking of icing of existing flat-bed that solves is installed.

3, the present invention can prevent marine denudation in-to-in vibration isolation and damping device at the leg post and open ice and be provided with packaging system between the conical inner surface, improves service life.

Description of drawings

Fig. 1 is a sectional structure scheme drawing of the present invention;

Fig. 2 is a plan structure scheme drawing of the present invention;

Fig. 3 is the structural representation of the steel-wire isolator of employing rubber encapsulation among the present invention.

The specific embodiment

Please as shown in Figure 1 and Figure 2, be the anti-ice vibrating device of a kind of above water platform provided by the present invention, it mainly includes one and is arranged on outer the opening ice awl 2 of above water platform leg post 1, and is arranged on leg post 1 and bores vibration isolation and damping device 3 between 2 with opening ice.Specifically, for make the awl 2 that opens ice can actv. contact ice face, therefore, the awl 2 that opens ice will be arranged near the water surface of above water platform leg post 1, promptly horizontal surface is up and down in the tidal level variation range.Awl 2 the inner wall shape that opens ice can determine according to the geometric configuration of vibration isolation and damping device 3, and the outer wall shape of the awl 2 that opens ice can be traditional coniform, also can adopt other shape, as the icebreaker shape etc.The described awl 2 that opens ice is non-ly can be fixed on the leg post 1 by vibration isolation and damping device 3 when coniform at its outside face, and also can making the awl 2 that opens ice serve as an axle rotation with leg post 1.

In order to prevent marine denudation vibration isolation and damping device 3, leg post 1 and opening ice is provided with in order to prevent the packaging system (not shown) of marine denudation interior arrangement between awl 2 inwalls.This packaging system can be water proof rubber or resilient High molecular material.

In addition, above-mentionedly state vibration isolation and damping device 3 and can be isolation spring or damper.Specifically, as shown in Figure 3, vibration isolation and damping device 3 is for adopting the steel-wire isolator of rubber encapsulation, and it includes: pedestal 31, be fixed in the vibration damping steel rope 32 on the pedestal 31, and the rubber 33 of vibration damping steel rope 32 outer packages.During installation, pedestal 31 is fixed on the leg post 1, rubber 32 is fixed on the awl 2 that opens ice.

The anti-ice method of slight of above water platform provided by the present invention is: near the anti-ice vibrating device that above-mentioned above water platform is installed the water surface of platform leg post on the water.

After adopting anti-ice method of slight of the present invention and specialized equipment, because flat-bed opens ice and between awl 2 and the leg post 1 vibration isolation and damping device 3 is set on the water, therefore the suffered ice load of platform will be by acting on the platform structure after 3 decay of vibration isolation and damping device, by the parameter of suitable selecting arrangement, can reach actv. vibration damping, vibration isolating effect.The invention process is simple, can not change the original design of platform substantially, even can carry out the back on legacy platform the anti-problem of shaking of icing of existing flat-bed that solves is installed.In addition, be provided with packaging system between 2 inwalls, can prevent marine denudation in-to-in vibration isolation and damping device, improve service life at the leg post 1 and the awl that opens ice.
