Abstract
The invention discloses one kind to damp plumb bob, including some damping vanes, the uniform radial distribution of damping vane form one in central cylinder outer wall with central cylinder；The central cylinder be inner hollow cylinder, its both ends open, either end set hoisting structure, its damping is good, technique is simple, it is easy to use, be favorably improved ship inclination test accuracy.
Description
Technical field
The present invention relates to a kind of plumb bob for hull inclining experiment.
Background technology
In ship inclination experiment, plumb bob is one of very important accessory.During ship inclination experiment, people is tested
Member needs to carry out the swing position of plumb bob reading, record and carries out correlation computations.The swing speed of plumb bob damps size with it
It is inversely proportional, and the swing speed of plumb bob is slower, then testing crew can be used for the time for reading record plumb bob position longer, resulting
Measurement result it is also relatively reliable.
In ship inclination experiment, typically require that plumb bob is immersed in liquid medium.Compared in air, plumb bob is in liquid
The stability of medium is higher.Conventional liquid medium is water, i.e., plumb bob is immersed in sizeable tank.
Traditional plumb bob is generally pyramid type, and damping is smaller, swings the reading difficulty for comparatively fast, adding testing crew, and
Measurement accuracy is not high.Plumb bob effective damping area with damping vane is smaller, the reduction plumb bob swing speed effect actually reached
Fruit unobvious, difficulty are still had during testing crew reading, measurement accuracy can not obtain strong guarantee.And the plumb bob
Parts are more, and the effect of gravity block is not notable, and the top of damping vane requires to use arc transition, and requires gravity block and damping
Blade is integrally formed, complicated construction technique.Occur a kind of medium by the use of oil instead of water as submergence plumb bob at present, and use this
Method will improve experimentation cost, thereby increases and it is possible to which environment is adversely affected.
Patent CN202923835U discloses a kind of damping plumb bob, and its composition is gravity block, damping vane and hanger.But this
The effective damping area of damping vane is smaller in scheme, the reduction plumb bob swing speed DeGrain actually reached, tests people
Difficulty is still had during member's reading, test accuracy can not obtain strong guarantee.And the parts of the plumb bob are more, gravity block
Effect it is not notable, the top of damping vane requires to use arc transition, and requires that gravity block is integrally formed with damping vane, applies
Work complex process.
And patent CN106143797A is by external environment condition due to without balancing weight, easily being disturbed, stabilization time is longer or nothing
Method is stable, it is difficult to ensures measurement accuracy, practical application difficulty.
The content of the invention
The purpose of the present invention be to overcome above mentioned problem, propose a kind of damping is good, technique is simple, it is easy to use, have
Help improve the damping plumb bob of ship inclination test accuracy.
Technical scheme includes some damping vanes, and the uniform radial distribution of damping vane is in outside central cylinder
Wall, one is formed with central cylinder；The central cylinder be inner hollow cylinder, its both ends open, either end set
Hoisting structure.This programme is taken for gravity block by central cylinder, to increase damping vane area, while is reduced parts, is added
Work manufacture craft simplifies.
Further, it is hanger for the ease of hanging, the hoisting structure, its both ends is fixed on the end of central cylinder,
Damping plumb bob is sling by hanger.
Further, it is eye plate for the ease of hanging, the hoisting structure, is directly opened in central cylinder one end.
Further, the damping vane quantity of central cylinder outer wall is preferably 6, and the damping vane is rectangle, both ends
Flushed with central cylinder.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the top view of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Diagram is closed, above-mentioned technical proposal is expanded on further.
A kind of New Damping plumb bob as depicted, including central cylinder 1, damping vane 2 and hanger 3.The damping leaf
Piece 2 contains 6 lamellar bodies, along the radially uniform distribution of central cylinder 1.The centrally disposed cylinder 1 of the hanger 3 and damping vane 2
Top.Coordinate central cylinder 1 to reduce swing speed by damping vane 2, be easy to reading to improve precision.
Radially uniform distribution of 6 lamellar bodies of damping vane 2 along central cylinder 1, it is connected by welding with central cylinder 1,
Hanger 3 is by welding or bolt connection in central cylinder 1 and the top of damping vane 2.
Radially uniform distribution of 6 lamellar bodies of damping vane 2 along central cylinder 1 so that damp the installation process of plumb bob more
Add conveniently, without specially adjusting the position of plumb bob, and can be compared with the damping of the whole plumb bob of performance of limits in all directions
Effect.
Central cylinder 1 is used to connect damping vane 2 and hanger 3, ensures the swaying direction of damping plumb bob.
Damping vane 2 plays damping action in plumb bob swing process.
Hanger 3 is used for bolt cycloid, forms swingable plumb bob.
Damping vane 2 may be designed as being easy to the rectangle of cutting, and hanger 3 can be bent with round steel and be formed, and simplify damping plumb bob
Processing technology thereof, reduce production cost.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent defines.
