[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 This invention provides a technical solution: a geotechnical structure stability testing device for geotechnical construction, comprising an installation cylinder 2 and an installation shell 7. The top of the installation cylinder 2 is provided with an air inlet pipe 1, and the bottom of the installation cylinder 2 is installed with a bottom shell 3. A pump body 6 is installed on the outer wall of the installation shell 7, and the water outlet pipe of the pump body 6 enters along the tangent of the installation shell 7. A connecting pipe 5 is installed at the bottom of the pump body 6. The device also includes: Sampling component 4 includes a rotating cylinder 407 disposed inside the mounting cylinder 2. A compression cover 412 is hinged in a groove opened on the outer wall of the rotating cylinder 407, and an opening corresponding to the compression cover 412 is opened on the outside of the mounting cylinder 2. A first guide groove 406 is opened at the top of the rotating cylinder 407. The fixing plate 404 is installed on the inner wall of the mounting cylinder 2 and is located at the top of the rotating cylinder 407. A connecting groove 405 is provided inside the fixing plate 404. Fixing block 408 is installed on the top of the rotating drum 407 and is slidably disposed inside the connecting groove 405; Sampling assembly 4 also includes: a fixing post 403, which is mounted on the top of the fixing plate 404; An electric push rod 401 is mounted on the top surface of a fixed plate 404. Both ends of the electric push rod 401 are equipped with connecting blocks 402. One end of the electric push rod 401 is rotatably connected to a fixed column 403, and the other end of the electric push rod 401 is rotatably connected to a fixed block 408 through a cylinder at the top of the fixed block 408. The extension and retraction of the electric push rod 401 pushes the fixed block 408 to move and drives the rotating drum 407 to rotate. The sampling component 4 also includes: a second guide groove 413, which is formed on the ground of the fixed plate 404 and corresponds to the first guide groove 406. The end of the second guide groove 413 is an arc-shaped groove coaxial with the rotating drum 407. The connecting rod 410 is disposed inside the extrusion cover 412, and a first connecting post 411 is installed at one end of the connecting rod 410. The first connecting post 411 is slidably disposed inside the first guide groove 406, and the top end of the first connecting post 411 is slidably disposed inside the second guide groove 413. By rotating the rotating drum 407, the first connecting post 411 is extruded by the first guide groove 406 and the second guide groove 413, thereby pushing the connecting rod 410 to move. The connecting seat 409 is installed on the inner wall of the extrusion cover 412 and is hinged to one end of the connecting rod 410. The connecting rod 410 is used to push the connecting seat 409 and the extrusion cover 412 to rotate.

[0029] The specific implementation is as follows: When soil is easy to sample, the installation cylinder 2 can be gradually inserted into the soil depth, and then the extension and retraction of the electric push rod 401 can be used to push the fixing block 408 to slide inside the connecting groove 405, thereby driving the rotating cylinder 407 to rotate. As the rotating cylinder 407 rotates, the extrusion cover 412 can gradually correspond to the opening opened by the installation cylinder 2. Furthermore, as the rotating drum 407 rotates, it can drive the first connecting column 411 to move through the first guide groove 406. Since the top of the first connecting column 411 is located inside the second guide groove 413, the first connecting column 411 can move within the second guide groove 413 under the drive of the first guide groove 406. Thus, the first connecting column 411 gradually moves outward with the rotation of the rotating drum 407 under the action of the first guide groove 406 and the second guide groove 413. Furthermore, the movement of the first connecting column 411 drives the connecting rod 410 to move, thereby pushing the extrusion cover 412 to rotate. This allows the extrusion cover 412 to extend out of the opening provided in the mounting cylinder 2 and extrude soil from the hole wall. The soil solution enters the mounting cylinder 2 through the permeation slits provided in the extrusion cover 412 for collection. At the same time, the air inside the mounting cylinder 2 can be extracted by connecting the air inlet pipe 1 to a pump or other structure, thereby creating a negative pressure inside the mounting cylinder 2 to facilitate the flow of soil solution into the mounting cylinder 2. Furthermore, after the collection is completed, the rotating drum 407 can be rotated by the electric push rod 401, which can also drive the extrusion cover 412 to retract. At the same time, since the end of the second guide groove 413 has an arc-shaped groove coaxial with the rotating drum 407, after the extrusion cover 412 rotates inward and fits against the outer wall of the rotating drum 407, it will no longer continue to rotate inward as the rotating drum 407 rotates. Thus, as the rotating drum 407 rotates, the extrusion cover 412 is misaligned with the opening provided on the mounting cylinder 2.

[0030] The discharge assembly 9 includes a guide plate 901 disposed on the inner wall of the bottom shell 3, and the surface of the guide plate 901 is provided with an arc-shaped guide groove. The discharge hopper 902 is installed at the bottom of the guide plate 901, and the wall of the discharge hopper 902 is composed of an elastic material phase, which allows the discharge hopper 902 to be stretched. The discharge assembly 9 also includes a discharge pipe 903, which is installed at the bottom of the discharge hopper 902 and passes through the bottom shell 3 and is connected to the connecting pipe 5. Support base 909 is installed inside the bottom shell 3, and the support base 909 has an opening in the middle corresponding to the discharge hopper 902. The top surface of the support base 909 has a second limiting groove 910. The discharge assembly 9 also includes: a limiting rod 907, one end of which is slidably installed inside the second limiting groove 910, and multiple limiting rods 907 are arranged circumferentially, with one end of each limiting rod contacting the other. A second connecting post 908 is installed at the top of the limiting rod 907, and one side of the limiting rod 907 is in contact with the discharge hopper 902. Turntable 905 is located at the top of support base 909, and a through hole corresponding to discharge hopper 902 is opened in the middle of turntable 905; The discharge assembly 9 also includes: a first limiting groove 904, which is formed on the surface of the turntable 905, and a second connecting post 908 is slidably disposed inside the first limiting groove 904; The second drive module 906 is disposed on the inner wall of the bottom shell 3, and the drive end of the second drive module 906 is connected to the turntable 905 through the teeth provided on the outer wall of the turntable 905.

[0031] The specific implementation is as follows: when the soil solution enters the installation cylinder 2 through the infiltration slit opened in the extrusion cover 412, the soil solution will flow to the surface of the guide plate 901, and then the soil solution can be guided through the arc groove on the surface of the guide plate 901 so that it can enter the discharge hopper 902. At the same time, the solution inside the discharge hopper 902 can be extracted through the pump body 6 and the connecting pipe 5. Furthermore, during the process of extracting the soil solution to the outside, the second drive module 906 can use the teeth on the outer wall of the turntable 905 to drive the turntable 905 to rotate. As the turntable 905 rotates, it squeezes the second connecting column 908 through the first limiting groove 904, thereby pushing the limiting rod 907 to move along the second limiting groove 910. This causes the ring formed by the limiting rod 907 to gradually decrease in size, thus squeezing the discharge hopper 902 through the limiting rod 907. Since the discharge hopper 902 is composed of a flexible material, the outlet diameter of the discharge hopper 902 changes under the squeezing of the limiting rod 907. This allows the pump body 6 to generate a local negative pressure at the outlet of the discharge hopper 902 when extracting the solution, which is beneficial for extracting the soil solution.

[0032] The separation component 8 includes a hopper 803 disposed on the inner wall of the mounting shell 7, and the bottom of the hopper 803 is provided with multiple storage troughs, and the storage troughs are provided with corresponding weighing devices. Rotating rod 807 is rotatably connected to hopper 803 through a through hole. A guide plate 801 is fixedly installed on the outer wall of rotating rod 807, and one side of the guide plate 801 is in contact with the surface of hopper 803. The separation assembly 8 also includes: a fixing cover 809, which is installed on the top of the rotating rod 807, and the inner side of the fixing cover 809 is provided with a groove corresponding to the guide plate 801. A spring 808 is installed inside the fixing cover 809, and the other end of the spring 808 is connected to the guide plate 801. Bevel gear 802 is mounted on the other end of rotating rod 807; The separation assembly 8 also includes: a support ring 806, which is installed on the inner wall of the mounting housing 7. The top of the support ring 806 is provided with a toothed disc 804, and the top of the toothed disc 804 corresponds to the conical surface of the bevel gear 802, and the toothed disc 804 meshes with the bevel gear 802. The first drive module 805 is disposed on the inner wall of the mounting housing 7, and the output end of the first drive module 805 meshes with the gear plate 804.

[0033] The specific implementation is as follows: when the pump body 6 sends the soil solution into the hopper 803, since the water outlet pipe of the pump body 6 enters along the tangent of the mounting shell 7, the soil solution can enter the interior of the hopper 803 along the tangential direction of the hopper 803. Furthermore, after the solution enters the hopper 803, it can be guided by the guide plate 801 so that it falls into the collection tank at the bottom of the hopper 803 for collection and testing. At the same time, the first drive module 805 drives the gear plate 804 to rotate, which in turn drives the bevel gear 802 to rotate, thereby driving the guide plate 801 to rotate. By changing the angle of the guide plate 801, the soil solution can be screened according to different standards. Since the guide plate 801 is made of rubber, the spring 808 can push the guide plate 801 to ensure that the guide plate 801 can contact the surface of the hopper 803.
