Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1 a to Figure 11, pond wave absorber of the invention includes elevating mechanism and water wheel arrangement, the water wheels dress
Put 1 to be made up of turbine blade 4, water wheels rotary shaft 17, fixed axle center 15, rolling bearing 16 and water wheels fixing axle 14, in wave
Sweep away drive water wheels and rotate reduction wave energy, reach fast wave-damping；Elevating mechanism includes two parts：Electric machine control system and water wheels are filled
The connection system with screw rod is put, mainly includes controlled motor 6, screw rod 3 (lifting screw), lifting draw-in groove 2, tune can be rotated
The position of wave absorber is saved, fixed point wave absorption is realized.
Further, the section blades edge shape of the water wheel arrangement has various, flat rectangular plate, semicircle, ellipse,
Gear shape, waveform and various mixing composition forms.And the section blades quantity of the water wheel arrangement is 5-9
Further, the section blades of the water wheel arrangement can be continuously or periodically interrupted on water wheels axial direction
Distribution.The section blades of water wheel arrangement total length of periodicity Disjunct distribution on water wheels axial direction accounts for pond width ratio
Should be more than 3/4.
Further, different grooves, projection, hollow hole/groove can be distributed on the blade of the water wheel arrangement.And it is described
The quantity of groove, projection, hollow hole/groove on the blade of water wheel arrangement is 3-6.On the blade of the water wheel arrangement
Groove, projection, the size of hollow hole/groove can be identical or be distributed in certain rule
The type of the ripple according to produced by the depth and wave maker in pond is needed to adjust water wheels wave absorption during wave absorption of the present invention
Height and position of the device in pond, starts controlled motor 6 first, and controlled motor output shaft 8 drives the tooth in rotation speed gear box 9
Wheel group is rotated, and the outbound course of transmission is changed so as to drive rotation speed gear box by the angular wheel of rotation speed gear box input 10
The ordinary gear of output end 11 is rotated, and then causes that the screw rod 12 of connection rotates；It is between screw rod 13 and water wheels fixing axle 14
Threaded connection, screw rod is rotated and causes that the height and position of water wheel arrangement changes.Elevating mechanism depends on lifting draw-in groove 2, left and right
Symmetrically, synchronization modulation.
The peak line or hollow line that wave is produced in ship model experimental tank are time-limited (for pond width), by water wheels
The axial length of device is arranged to suitable with pond width, can more fully reach the purpose of wave absorption.When wave 5 is delivered to water
During wheel apparatus, because wave has certain energy and current form can be kept to move on so that wave is filled with water wheels
Energy transfer is there occurs between putting, is input into due to the owned certain quality of water wheel arrangement and without artificial external energy, because
This part wave energy changes into the energy needed for water wheels are rotated, and the energy of wave is decayed rapidly when by water wheel arrangement, so as to reach
To the purpose of wave absorption, as shown in figure 5, wave first reaches water wheels the latter half, water wheels rotate according to the direction of A；Wave is first reached
Water wheels top half, water wheels rotate according to the direction of B, and C refers to that elevating mechanism adjusts water wheel arrangement in the position of pond depth direction
Putting can realize fixed position wave absorption nearby.
To sum up, present invention design is a kind of ship model experimental tank wave absorber, including elevating mechanism and water wheel arrangement；The liter
Descending mechanism is distributed in the left and right sides, drives lifting tooth roller box to rotate by the output shaft of lifting motor and is connected with lifting screw, rises
Drop screw rod is placed in inside lifting draw-in groove, and water wheel arrangement is adjusted by lifting screw rotation in the position of pond depth direction；
The water wheel arrangement includes fixing axle, rotary shaft, rotates water wheels, rotates and waterproof watertight bearings support is used between water wheels and fixing axle
Connection.The action principle of apparatus of the present invention is：Water wheels are adjusted in the position of pond depth direction by lift so that by making ripple
The wave that machine is produced drives water wheel arrangement to rotate when being delivered to pond opposite bank, and then weakens the energy of wave, is finally reached quick
The purpose of wave absorption, and the circumferential same sex that water wheel arrangement has is not so that water wheels have sensitiveness for the incidence angle of wave.This hair
Bright to be readily produced manufacture, easy to use, wave absorption speed is fast, and effect is good, can be greatly enhanced the test efficiency of ship model experimental tank, and
Test accuracy can largely be improved；The device is applicable not only to general pull-type ship model experimental tank, and can be applicable
In the wave absorption of other kinds small-sized tank.
