[0014] (1) In this utility model, a suspension mechanism is introduced into the loess landslide simulation test system. After the simulation test is officially started, the suspension mechanism is used to lift the inclined panel bearing the loess for the test to the predetermined simulated slope position.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a physical simulation test device for loess landslides, including a main body 1. To address the problem that in loess landslide physical simulation tests, the adjustment components are typically placed at the bottom, and when soil slides down, the adjustment components are buried, affecting their operation. The main body 1 of the simulation test device is equipped with a soil recovery trough 2 and a top plate 3. An inclined plate 4 is installed below the top plate 3, positioned above the soil recovery trough 2. A suspension mechanism 5 is provided on the inclined plate 4, and a cleaning mechanism 6 is provided inside the soil recovery trough 2. During loess landslide simulation, the inclined plate 4, which carries the loess, is lifted by the suspension mechanism 5. By placing the adjustment components above the inclined plate 4, the loess is prevented from burying the adjustment components during landslides, thus preventing them from affecting their operation. The cleaning mechanism 6 cleans the loess that has slid into the soil recovery trough 2.

[0023] The suspension mechanism 5 includes a front lifting rod 501 and a rear lifting rod 502, which are fixedly installed below the top plate 3. A crossbar 503 is installed below each of the front and rear lifting rods 501 and 502. A front connecting rod 504 and a rear connecting rod 505 are fixedly installed below each of the two crossbars 503, respectively. Both the front and rear connecting rods 504 and 505 are rotatably mounted on the inclined panel 4. The slope of the inclined panel 4 is adjusted by the extension and retraction of the front and rear lifting rods 501 and 502. Landslide simulations were conducted on loess slopes of varying gradients. A rear pivot 506 was installed on one side of the inclined panel 4, and two rear connecting rods 505 were rotatably mounted on the rear pivot 506. Front pivots 507 were fixedly installed on both sides of the inclined panel 4, and front pivot grooves 508 were fixedly installed below the two front connecting rods 504. The front pivots 507 were slidably mounted in the front pivot grooves 508. When adjusting the slope of the inclined panel 4, the front pivots 507 could slide within the front pivot grooves 508 to prevent the angle of the inclined panel 4 from changing and causing it to jam.

[0024] Example 2: Figure 2 and 4 The cleaning mechanism 6 includes a cleaning plate 601, which is slidably installed inside the soil recovery tank 2. A horizontal shaft 602 is installed on the cleaning plate 601. Side horizontal shaft grooves 603 are provided on both sides of the soil recovery tank 2. The two ends of the horizontal shaft 602 are slidably installed in the side horizontal shaft grooves 603 respectively. Side rails 604 are installed on both sides of the soil recovery tank 2. Horizontal shaft connectors 605 are installed at both ends of the horizontal shaft 602. The bottom of the horizontal shaft connectors 605 is slidably installed in the side rails 604. The side horizontal shaft grooves 603 and the side rails 604 simultaneously guide and limit the horizontal shaft 602 to prevent cleaning... During the sliding process, the plate 601 deflects, causing wear or jamming of the inner wall of the cleaning plate 601 and the soil recycling tank 2. The bottom surface of the soil recycling tank 2 is sloped, and the side horizontal shaft groove 603, the side track 604 and the bottom surface of the soil recycling tank 2 have the same slope. A cleaning port 606 is provided on one side of the soil recycling tank 2. A hinge 607 and a locking component 608 are provided on the cleaning port 606. The cleaning port 606 is located at the lowest point of the slope inside the soil recycling tank 2. The cleaning port 606 can be opened by the hinge 607 and the locking component 608 to clean the loess in the soil recycling tank 2. The remaining features are the same as in Embodiment 1.

[0025] The working principle is as follows: When simulating a loess landslide, the inclined panel 4 bearing the loess is lifted by the suspension mechanism 5, and loess is laid on the inclined panel 4. Then, the slope of the inclined panel 4 is adjusted by the extension and retraction of the front lifting rod 501 and the rear lifting rod 502. Landslide simulation is carried out on loess with different slopes. By setting the adjustment component above the inclined panel 4, the loess is prevented from burying the adjustment component during the landslide, thus affecting the operation of the adjustment component. After the loess slides from the inclined panel 4 into the soil recovery trough 2, the cleaning port 606 is opened by the locking component 608 and the hinge 607. Then, the horizontal shaft connector 605 drives the horizontal shaft 602 and the cleaning plate 601 to slide from the highest point of the slope in the soil recovery trough 2 towards the cleaning port 606, pushing the loess that has fallen into the soil recovery trough 2 out of the soil recovery trough 2 through the cleaning port 606, cleaning the soil recovery trough 2, which is convenient for subsequent simulation tests.
