[0024] Compared with the prior art, the landslide test device has the advantages that:

[0025] Through the base 100, the support mechanism, the vibration mechanism and the interception mechanism, the support mechanism can support and adjust the angle of the simulated slope 110, the vibration mechanism can apply vibration to the simulated slope 110 to simulate the actual situation of the landslide, and the interception mechanism can intercept the rolling stones falling from the simulated slope 110 to simulate the protection strength of different degrees of landslide falling stones. The severity of the landslide can be predicted by simulating the influence of natural disasters on different slopes, and the protection strength of the landslide can be tested at the same time, so that the disaster caused by the landslide can be better protected.

[0026] The landslide test device has the advantages of simple structure and easy implementation, is suitable for installation and use in existing landslide tests, has low use cost and can improve efficiency.

[0027] In the embodiment, as shown in the drawings, Figures 1-6 The support mechanism comprises a support plate 210 and an angle adjusting assembly, the support plate 210 comprises opposite bottom and top edge portions, the base 100 comprises opposite front and rear edge portions, the bottom edge portion of the support plate 210 is hinged to the front edge portion of the base 100, so that the support plate 210 can rotate relative to the rear edge portion of the base 100, and the angle adjusting assembly is installed on the base 100 and located below the support plate 210 and is used for adjusting the inclination angle between the support plate 210 and the base 100.

[0029] In the embodiment, as shown in the drawings, Figures 1-6As shown in the figure, the angle adjusting assembly comprises a cylinder 220 and a sliding rail 230, the cylinder 220 comprises opposite fixed ends and pushing ends, the fixed ends are fixedly arranged on the base 100, the sliding rail 230 is arranged on the bottom surface of the support plate 210 and corresponds to the pushing ends of the cylinder 220, a top support sliding block 240 is slidably arranged on the sliding rail 230, and the pushing ends of the cylinder 220 extend upward and are hingedly connected with the top support sliding block 240.

[0030] In this way, the cylinder 220 can push the support plate 210 to adjust the angle, and the interference between the cylinder 220 and the support plate 210 can be avoided with the assistance of the sliding rail 230 and the top support sliding block 240 during the pushing process, and the pushing structure is relatively simple and reliable.

[0031] In this embodiment, as shown in the figure, Figures 1-6 As shown in the figure, the vibration mechanism comprises a vibration plate 310, an elastic column assembly, a first motor 320 and a rotating cam, the vibration plate 310 is arranged above the support plate 210 and is arranged in parallel with the support plate 210, the elastic column assembly is connected and arranged between the support plate 210 and the vibration plate 310, the first motor 320 is installed on the support plate 210 and located between the support plate 210 and the vibration plate 310, and the rotating cam is drivingly connected to the rotating shaft of the first motor 320 and abuts against the vibration plate 310, so as to drive the vibration plate 310 to vibrate back and forth in a direction perpendicular to the surface of the support plate 210.

[0032] In this way, the vibration plate 310, the elastic column assembly, the first motor 320 and the rotating cam are arranged, so that the vibration plate 310 can vibrate back and forth in a direction perpendicular to the surface of the support plate 210 under the action of the first motor 320 and the rotating cam, so as to drive the simulated slope 110 to vibrate, and the vibration structure is relatively simple.

At the same time, by setting the telescopic rod 340 and the tension spring 350, the support plate 210 and the vibrating plate 310 can both generate relative displacement and perform reset movement of the vibrating plate 310, making the structure more reliable.

[0036] During implementation, the tension spring 350 is in a stretched state when it is lifted by the cam, which enables the vibrating plate 310 to automatically reset.

[0042] In this way, the second motor 430, the transmission shaft 440 and the transmission block 450 are arranged, so that the second motor 430 can drive the transmission block 450 to move up and down, thereby driving the top surface of the barrier net 420 to move up and down, and the barrier net 420 can be unfolded and folded, and the unfolding and folding structure is relatively simple.
