[0033] A model test geosyncline 1 is used to construct a test model by using similar materials. A geosyncline discharge passage is arranged at the bottom of the model test geosyncline 1, and the similar materials flow out of the geosyncline discharge passage.

[0034] A cleaning pool 5 is arranged with a separation device. The similar materials are cleaned in the cleaning pool 5. The similar materials that are insoluble in water are separated out of the cleaning pool 5 by the separation device. The similar materials that soften when in contact with water are precipitated to the bottom of the cleaning pool 5.

[0035] A first lifting device 2 is arranged between the model test geosyncline 1 and the cleaning pool 5. One end of the first lifting device 2 is connected to the outlet of the geosyncline discharge passage, and the other end is connected to the top inlet of the cleaning pool 5.

[0036] A storage pool 11 is used to temporarily store the similar materials that are insoluble in water separated by the separation device. The bottom of the storage pool 11 is arranged with a storage pool 11 discharge passage. The similar materials that are insoluble in water flow out of the storage pool 11 for reuse.

[0037] In the automatic cleaning and filling device, after the test is completed, water is injected into the model test geosyncline 1 to soften the similar materials. The softened similar materials flow out of the geosyncline discharge passage arranged at the bottom of the model test geosyncline 1. The first lifting device 2 lifts and transfers the similar materials flowing out of the geosyncline discharge passage to the top of the cleaning pool 5 and pours them into the cleaning pool 5 from the first lifting device discharge port 4 at the top of the cleaning pool 5. In the cleaning pool 5, part of the similar materials dissolves in water, and the similar materials that are insoluble in water fall on the separation device and are separated by the separation device to the storage pool 11 for temporary storage. When it is necessary to construct a test model and prepare similar materials, the similar materials that are insoluble in water in the storage pool 11 flow out of the storage pool 11 discharge passage for reuse. The automatic cleaning and filling device greatly improves the cleaning efficiency of the test materials after the test is completed and can realize the reuse of part of the used materials.

[0038] The separation device comprises a filtering assembly and a driving assembly. The filtering assembly is used to filter out the similar materials that are insoluble in water. The driving assembly is used to drive the filtering assembly to reciprocate vertically in the cleaning pool 5.

[0039] In one embodiment of the present application, the similar material main material is composed of gypsum and steel balls, wherein the gypsum is a water-softening material, and the steel balls are water-insoluble materials; when the similar material is transported to the cleaning pool 5, the gypsum softens in water and falls to the bottom of the cleaning pool 5 through the filter assembly, and the water-insoluble steel balls fall on the filter assembly, and the filter assembly is driven upward by the driving assembly to separate the steel balls from the gypsum, the steel balls on the filter assembly are transported to the storage pool 11 for temporary storage for reuse, and then the filter assembly is moved downward and the similar material is introduced into the cleaning pool 5, and the above steps are repeated to continuously separate the steel balls in the similar material.

[0045] The upper surface of the filter framework 7 is inclined towards the slope channel 10, and the upper surface of the filter framework 7 has an inclination of at least 3%; when the filter assembly is lifted to the same height as the slope channel 10, the steel balls on the filter assembly roll towards the slope channel 10 under the action of gravity, and enter the storage pool 11 through the slope channel 10.
