Description
Technical field
This utility model relate to wave current model test apparatus, specifically one disappear wave overflow means.
Background technology
In wave current model test, if the wave of test section end can not be cut down in time, will incite somebody to action after meeting with model abutment wall
Form echo, thus result of the test is brought certain adverse effect, the therefore quality of test section end equipment wave absorbing effect
The success or failure of test wave current simulation will be determined.
In conventional wave flume, wave elimination facility mostly is block stone ramp structure and the gradient is relatively slow (generally 1/5～1/8),
Wave absorbing effect preferably (reflectance is low, can be close to or smaller than 0.1), but this adverse grade structure needs to take more tank length, when
Have a strong impact on tank when the depth of water is bigger and made wave band and the length of efficiency test section, thus brought all to the layout of model test
The most inconvenient.Therefore, in wave current model test, general employing is stacked the disappear method of wave material of porous and is carried out disappearing wave (as directly stacked
French drain material or bamboo broom etc.), which for the pure rough-water test without stream wave absorbing effect still can, but there is also movement
Regulating power is poor, shortcoming to different in flow rate Yu the bad adaptability of wave combination condition, and conveyance capacity is the most unsatisfactory, even if
Having certain conveyance capacity, conveyance capacity is the most unadjustable, manually rearranges the test group time needs of different in flow rate, automatically
The backwardness of change degree result also in the low of test efficiency.It is badly in need of a kind of energy for wave and tidal co-action test of research and development at present same
Time disappear wave and cross stream device.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model be not limited to
Lower embodiment.
The wave overflow means as it is shown in figure 1, a kind of tracking mode disappears, crosses stream including fixed support 1, main body rack 2 and the wave that disappears
Net.
Described fixed support is steel frame construction (entirety is welded by angle steel), as in figure 2 it is shown, the base bottom fixed support
Seat 11 is fixed on the ground outside tank by setscrew, and the support bar 12 at fixed support top extends horizontally on tank
Side；The both sides of described tank respectively arrange a fixed support.
Described main body rack suspends in midair in the sink by fixed support, and each fixed support is equipped with for driving main body
The elevating mechanism of support vertical lifting；Described elevating mechanism includes the elevating screw 51 being vertically arranged, for coordinating elevating screw
Lifting nut, for driving the lifting motor 52 that lifting nut rotates；Described elevating screw can be fixed rotationally around vertical axis
Position is on the support bar 12 at fixed support top, and described lifting nut is connected (this connection with the link 21 at main body rack top
Mode is routine techniques).This elevating mechanism can drive main body rack stably to move up and down, by regulating ground clearance thus big
Dimension regulates the wave conveyance capacity that disappears.
Described elevating mechanism is additionally provided with guide rail mechanism, including riser guide 61 and the lifting pulley that coordinates with riser guide
62；Described riser guide is vertically fixed on bottom main body rack, and described lifting pulley can be positioned at water rotationally around horizontal axis
Trench bottom, this guide rail mechanism ensure that main body rack the most vertically lifts.
As it is shown in figure 1, described main body rack is frame structure, some waves that disappear are crossed drift net and are arranged in main body rack, these
The wave that disappears is crossed drift net and is set gradually arrangement (the length side that horizontal direction is main body rack of Fig. 1 along the length direction of main body rack
To and wave current direction), in process of the test wave current will the most vertically pass through all of disappear wave cross drift net.The described wave that disappears
Cross drift net and include the auxiliary stand 31 extending to the whole overflow section of tank and the french drain material 32 being arranged on auxiliary stand
(also known as plastic blind-ditch, buyable obtains)；The quantity that the described wave that disappears crosses drift net is four layers.
It is positioned at the wave that disappears of rear and front end to cross drift net and be fixed on the two ends of main body rack length direction (auxiliary stand props up with main body
Frame is fixed), remaining wave that disappears is crossed drift net (middle two-layer disappear wave cross drift net) and is then positioned at master by translation mechanism horizontally moveablely
In body support frame.Some translation screw mandrels 41 that described translation mechanism includes being horizontally fixed in main body rack and be parallel to each other, for
Coordinate the translational nut of translation screw mandrel and for the translation motor 42 driving translational nut to rotate, described translational nut and the wave that disappears
The auxiliary stand crossing drift net connects (this connected mode is routine techniques).This translation mechanism can regulate the middle two-layer wave that disappears and cross stream
Net and the rear and front end wave that disappears crosses the relative distance of drift net, thus obtains different wave absorbing effect.
It is additionally provided with control module 16, lifting motor and translation motor on described fixed support and is sent instruction by control module
It is controlled.The core of control module is 51 single-chip microcomputers, needs the parameters such as pre-entered wave height, flow velocity before the test, and parameter is by control
The TIP input of molding block, according to programming, this utility model is pre-adjusted the ground clearance of main body rack and disappears
Wave crosses the spacing of drift net.In process of the test, control module can according to wave-height gauge 14 and the data of current meter 15 Real-time Collection,
The wave conveyance capacity that disappears of judgment means is the most suitable, and regulates and revise the ground clearance of main body rack in real time according to program feedback
With disappear wave cross drift net relative position, it is achieved optimum disappear wave cross fluidity can tracking mode regulation.For monitoring and Real-time Collection ripple
Height, the wave-height gauge of flow speed data and current meter are laid in position, 5 meters, this utility model front end (in face of wave current incident direction), wave height
Instrument and current meter by holding wire Access Control module and all pass through mains-supplied.
It addition, according to the practical situation of experimental enviroment, test water body may be mixed into the foreign material of some wadding classes, along with
Wave, the common effect of current and be attached on french drain material, thus reduce the wave conveyance capacity that disappears.Therefore the wave mistake that disappears of high order end
Drift net is provided with warp layer net 33, and french drain material thus can be avoided to be blocked by various tiny foreign material too quickly as far as possible, it is ensured that this
Disappear wave and the conveyance capacity of utility model.
