Description
Technical field
The present invention relates to a kind of auxiliary wave absorbers more particularly to a kind of ship model test towing tank to assist wave absorber.
Background technique
Ship model test towing tank is a kind of equipment of hydrodynamics experiment, can usually carry out ship model resistance test, try from boat
It tests, the fluids correlation test such as seakeeping test and propeller open-water test.The pond body in pond is reinforced concrete structure, usually
Rectangle, is equipped with track on the pool wall of pond two sides, and trailer moves ahead in orbit.Being equipped in one end of ship model test towing tank can
The wave maker of formation rule and irregular wave in pond, the other end are typically provided with wave absorption bank and dock.When progress large scale, height
When speed of a ship or plane ship model experiment is with wave test is made, even if pool end is equipped with wave absorption bank, the water surface of fluctuation still needs very long waiting
It can just restore calm, can just continue the test of next operating condition.In view of expensive experimentation cost, need as far as possible
The water times such as reduction.For this situation, a kind of two-way auxiliary wave absorption suitable for ship model test towing tank of invention is filled
It sets.
Summary of the invention
It is that one kind is readily produced system the purpose of the invention is to provide a kind of ship model test towing tank auxiliary wave absorber
Make, using with it is easy to operate, wave dissipation effect is good, can be improved the ship model test towing tank of ship model test towing tank experimental precision and efficiency
Wave absorber.
The object of the present invention is achieved like this: including two screw elevators being mounted on the wave absorption bulkhead wall face of pond
Structure, the clipping wall being arranged between Liang Ge spiral lift mechanism, uniformly it is in a row be mounted on clipping wall can bidirectional rotation
Three leaves fan, each spiral lift mechanism include fixed frame, the built-in motor being mounted on fixed frame, with built-in motor export
It holds the screw rod of connection, the sliding block on screw rod is installed, the both ends of the clipping wall are connected respectively at corresponding sliding block.
The invention also includes structure features some in this way:
1. be evenly arranged with long stripes through hole and circular through hole on the clipping wall, and long stripes through hole and circular through hole at
Row is alternately arranged.
2. the blade surface of three leaf fan is uniformly arranged fluted, three leaves fan is double-sided symmetrical structure.
Compared with prior art, the beneficial effects of the present invention are: having on clipping wall of the invention equally distributed round logical
Ripples can be dispersed into tiny breaker, cut down the energy of water surface wave by hole and long stripes through hole.According to ship model test towing tank
Size, by appropriate number of three leaf fan be mounted in clipping wall.Three leaves fan be located at the water surface hereinafter, surface have it is equally distributed small
Groove can increase frictional resistance, consume the energy of water surface ripples below, while the underwater wave by approximately level will drive three leaves
Fan rotation, converts mechanical energy for Water wave energy.Three leaves fan is double-sided symmetrical structure, can be reflected with bidirectional rotation from wave absorption bank
Wave back also can be by the device by secondary abatement.The both ends of clipping wall are equipped with spiral lift mechanism, elevating mechanism
It is fixed on the pool inner wall face of pond wave absorption bank, control switch is mounted in the outside wall surface in pond.When trailer will pass in and out
When dock, which can be dropped and be moved ahead in the water surface hereinafter, not influencing trailer.

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
Referring to Fig.1,2, the present invention includes clipping wall 1, three leaves fan 2 and spiral lift mechanism 3.Have on clipping wall and uniformly divides
Ripples, can be dispersed into tiny breaker by the circular through hole 4 and long stripes through hole 5 of cloth, to cut down the energy of water surface wave.
According to the size of ship model test towing tank, appropriate number of three leaf fan is mounted in clipping wall, the both ends of clipping wall are equipped with spiral shell
Rotating elevating mechanism 3, elevating mechanism are fixed on the pond wall surface close to pond wave absorption bank, and the elevating mechanism is by screw rod 7, solid
Determine the composition such as frame 8, built-in motor and control system.
Referring to Fig. 3, three leaves fan is located at the water surface hereinafter, there is equally distributed little groove 6 on surface, can increase frictional resistance,
The energy of water surface ripples below is consumed, while the underwater wave by approximately level will drive the fan rotation of three leaves, and Water wave energy is converted
For mechanical energy.Three leaves fan is double-sided symmetrical structure, can also pass through the device from the reflected wave of wave absorption bank with bidirectional rotation
And by secondary abatement.
Referring to Fig. 4, elevating mechanism is fixed on the pool inner wall face of pond wave absorption bank A, and control switch is mounted on water
In the outside wall surface in pond.When trailer will pass in and out dock, which can be dropped and be moved ahead in the water surface hereinafter, not influencing trailer C.When by
When caused ripples pass through the wave absorber after the high speed of a ship or plane, the navigation of large scale ship model or wave maker B start to work, the energy of ripples
Amount can be weakened, then cooperate the effect of pond wave absorption bank, finally the water surface can be restored calm in a short period of time, to subtract
Less the equal water time, conventional efficient is improved, reduces experimentation cost.
To sum up, the present invention can cooperate wave absorption bank, play the role of assisting wave absorption.The wave of water surface passes through energy after clipping wall
Enough effectively abatements.It will drive the fan rotation of three leaves by the wave of approximately level, convert mechanical energy for Water wave energy.Processing and fabricating of the present invention
Simple process, it is easy to operate and do not influence trailer disengaging dock, the equal water time can be effectively reduced, to improve ship model towing water
The conventional efficient in pond.After the present invention changes proportional sizes, it is readily applicable to the wave absorption of all kinds of sinks.
