The simulation setting unit 110 includes bottom plate, and the edge of the bottom plate is disposed with multiple limitation baffles, each limit
The region that baffle processed surrounds is exactly the region tested, and the bank slope protection structure simulated during guarantee test is indeformable, makes experiment
It is normally carried out.In the present embodiment, the quantity for limiting baffle is four, and the area size surrounded is 740 × 740mm, and depth is
50mm.The inductive component is arranged therein the edge residing for a limitation baffle, which cuts with scissors with described device pedestal 120
It connects, therefore the bottom plate can be rotated in the hinged place, the angle of bottom plate and horizontal plane can be changed, reach the effect of multi-angle oblique
Fruit.In addition, to mitigate the weight of the simulation setting unit 110, the back side of bottom plate is designed as grid-like.
In the present embodiment, four limitation baffles, sliding force induction baffle and bottom plate should select that rigidity is big, deformation is small, matter
The relatively light material manufacture of amount, and the deformation of the material influenced by temperature, humidity it is smaller, such as aluminium alloy, acrylic material
Material etc..
In the present embodiment, the limitation baffle at edge where the inductive component is movable limitation baffle, after the test,
Movable limitation baffle and sliding force induction baffle can be removed together, be convenient to clean simulation setting unit 110.
The inclined shore component includes lead screw of the frame in described device pedestal 120, and sliding block 124 is cased on the lead screw,
It is disposed with tapped through hole on the sliding block 124, the supporting rod 123 for jacking up the bottom plate, the bottom are hinged on the sliding block 124
The sole arrangement of plate has the protrusion for heading on the supporting rod 123.One end of the lead screw is disposed with rotational handle 122, by turning
Dynamic lead screw makes sliding block 124 move, to linearly change the angle of the supporting rod 123 and horizontal plane.
In the present embodiment, described device pedestal 120 is tower structure, therefore has enough spaces in device pedestal 120
