[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] A foundation detection device for water conservancy projects, as Figure 1-8 shown, includes a bottom plate 1. A plurality of moving wheels are movably installed on the bottom surface of the bottom plate 1. One side of the top surface of the bottom plate 1 is fixedly installed with a vertical plate 2. A groove is formed on the top surface of the vertical plate 2, and a plurality of first cylinders 3 are embedded and installed in the groove. An L-shaped plate 4 is arranged above the vertical plate 2. The bottom end of the vertical plate of the L-shaped plate 4 can be inserted into the groove, and the bottom end of the vertical plate of the L-shaped plate 4 is fixedly connected to the top end of the moving end of the first cylinder 3. A driving assembly is installed on the bottom surface of the horizontal plate of the L-shaped plate 4. A guiding assembly is installed on the bottom surface of the horizontal plate of the L-shaped plate 4. A gravity block 5 is installed on the guiding assembly. The driving assembly drives the gravity block 5 to move in the vertical direction. A plurality of second cylinders 6 are fixedly installed on the outer surface of one side of the vertical plate of the L-shaped plate 4. The bottom ends of the moving ends of the plurality of second cylinders 6 are fixedly connected by a horizontal plate 7. A through hole is formed on the top surface of the horizontal plate 7, and a sleeve 8 that is transparent at both the upper and lower ends is slidably installed in the through hole. A rotating guiding assembly is installed at the bottom end of the horizontal plate 7. The rotating guiding assembly can guide the sleeve 8 and can control the sleeve 8 to rotate. A detection assembly is detachably installed in the sleeve 8.

[0020] On the other side of the top surface of the bottom plate 1, a counterweight is installed to adjust the balance of the bottom plate 1. The second cylinder 6 is located on the left side of the horizontal plate 7. After the sleeve 8 is inserted into the through hole, the sleeve 8 is located below the gravity block 5. The detection assembly consists of different test components, specifically: the detection assembly for dynamic penetration testing and the detection assembly for shear strength testing. A winch hoist is installed on the top surface of the horizontal plate of the L-shaped plate 4 (not shown in the figure). By rotating the moving wheels, the bottom plate 1 can be controlled to move to the detection point. Then, the second cylinder 6 extends to push the horizontal plate 7 downward. At the same time, the first cylinder 3 extends to control the L-shaped plate 4, the driving assembly, and the guiding assembly to move upward, expanding the space between the guiding assembly and the horizontal plate 7. Then, the sleeve 8 is inserted into the through hole, and the sleeve 8 passes through the rotating guiding assembly. At this time, the detection assembly for dynamic penetration testing is installed inside the sleeve 8, and the bottom end of the sleeve 8 contacts the ground. Then, the first cylinder 3 extends or contracts to adjust the distance between the gravity block 5 and the sleeve 8, controlling the kinetic energy released during the downward fall of the gravity block 5. After the adjustment is completed, the driving assembly controls the gravity block 5 to fall downward. The gravity block 5 contacts the sleeve 8 and drives the sleeve 8 and the internal detection assembly into the soil. The driving assembly repeatedly controls the gravity block 5 to fall downward, gradually driving the sleeve 8 and the detection assembly into the soil. The bearing capacity of the foundation is detected by the resistance of the detection assembly penetrating into the soil. After the detection is completed, the detection assembly is lifted out of the sleeve 8 by the winch hoist, and the sleeve 8 is still located in the soil. The sleeve 8 protects the hole from collapsing. Then, the detection assembly for shear strength testing is placed into the sleeve 8. The rotating guiding assembly is used to control the sleeve 8 to rotate, driving the detection assembly to rotate. The detection assembly is used to measure the shear strength and torsional peak value of the foundation. During the measurement of the shear strength and torsional peak value, the driving assembly is separated from the gravity block 5, and the gravity block 5 contacts the sleeve 8. The weight of the gravity block 5 gives the sleeve 8 a downward force, causing the sleeve 8 and the detection assembly to move downward for the measurement of the shear strength and torsional peak value.

[0021] Specifically, the driving assembly described in this embodiment includes a multi-stage telescopic rod 9. An electromagnet is fixedly installed on the mobile base of the multi-stage telescopic rod 9, and an iron sheet is fixedly installed on the top surface of the gravity block 5. The multi-stage telescopic rod 9 can be an electric multi-stage telescopic rod. When the gravity block 5 is at the lowest end, the multi-stage telescopic rod 9 extends to push the electromagnet downward. The electromagnet contacts the iron sheet, and the electromagnet is energized to adsorb the iron sheet. Then, the multi-stage telescopic rod 9 contracts to lift the gravity block 5 upward to the topmost position. Then, the electromagnet is powered off. Under the action of gravity and the weight of the gravity block 5, the gravity block 5 falls downward to hammer the sleeve 8, driving the sleeve 8 and the detection assembly into the soil.

[0022] Further, the guiding assembly described in this embodiment includes several guiding rods 10. The top ends of the guiding rods 10 are fixedly connected to the bottom surface of the horizontal plate of the L-shaped plate 4. A guiding sleeve 11 is slidably mounted on the guiding rods 10. The side end of the guiding sleeve 11 is fixedly connected to the side end of the gravity block 5. A limiting block is fixedly installed at the bottom end of the guiding rod 10. The several guiding rods 10 enclose the gravity block 5 in a space. Through the fitting of the guiding rod 10 and the guiding sleeve 11, during the downward movement of the gravity block 5, deviation can be avoided, and all the kinetic energy released by the gravity block 5 can fall onto the sleeve 8. Moreover, during the upward lifting process, the deviation of the gravity block 5 can also be avoided, and the gravity block 5 moves in the vertical direction, which can position the electromagnet and the iron sheet, making the electromagnet contact the iron sheet and preventing the dislocation between the electromagnet and the iron sheet, resulting in better effects in use. The limiting block can prevent the guiding sleeve 11 from moving out of the guiding rod 10.

[0023] Still further, the rotating guiding assembly described in this embodiment includes: An annular groove 12, which is opened on the bottom surface of the horizontal plate 7. The annular groove 12 is concentric with the through hole, and the transverse cross-section of the annular groove 12 is dovetail-shaped; A guiding cylinder 13, which is transparent at both the upper and lower ends. Several sliders are fixedly installed at the top end of the guiding cylinder 13. The transverse cross-section of the sliders is dovetail-shaped, and the sliders can be inserted into the annular groove 12. Guide blocks are respectively fixedly installed on the inner walls of the front and rear ends of the guiding cylinder 13; A first gear 14, the guiding cylinder 13 passes through the central hole of the first gear 14 and is fixedly connected to the central hole of the first gear 14; A rotating motor, which is fixedly installed on the bottom surface of the horizontal plate 7. A second gear is fixedly installed at the bottom end of the output shaft of the rotating motor, and the second gear can be meshed with the first gear 14; Two long slots 15, the number of the long slots 15 is two. The two long slots 15 are respectively opened on the outer surfaces of the front and rear ends of the sleeve 8. The bottom end of the long slot 15 communicates with the outside, and the guide block can be inserted into the long slot 15.

[0024] The rotating motor can adjust its rotational speed under the control of the controller. The sleeve 8 is inserted into the through hole and passes through the guiding cylinder 13. At the same time, the guiding block is inserted into the long slot 15. During the dynamic penetration test, the gravity block 5 drives the sleeve 8 and the detection component into the soil. The guiding cylinder 13 guides the sleeve 8 to prevent the sleeve 8 from shifting during the process of entering the soil. When the dynamic penetration test is over, a new detection component is replaced. The rotating motor controls the second gear to rotate. Through the cooperation of the second gear and the first gear 14, and the weight of the upper gravity block 5, the sleeve 8 drives the detection component to rotate into the soil for shear strength test and measurement of the torsional peak value. Multiple tests are carried out through one component, and the sleeve 8 in the soil can protect the hole to prevent the hole from collapsing.

[0025] Furthermore, the sleeve 8 in this embodiment includes a cylinder body 801 and an annular block 802. The annular block 802 is fixedly installed inside the cylinder body 801 and is located at the top inside the cylinder body 801. Two insertion holes 803 are respectively opened on both sides of the top end of the annular block 802. A long slot 15 is opened on the outer surface of the cylinder body 801. The detection component is placed inside the cylinder body 801 and passes through the annular block 802. The annular block 802 can prevent the detection component from passing through the cylinder body 801, and the components on the detection component cooperate with the insertion holes 803 to limit the detection component and prevent the detection component from shaking.

[0026] Furthermore, the detection component in this embodiment includes a connecting piece and a detecting piece. The detecting piece is detachably installed on the connecting piece; The connecting piece includes a round block 16, a first cylinder 17, and a second cylinder 18. The top surface of the first cylinder 17 is fixedly connected to the bottom surface of the round block 16, and the top surface of the second cylinder 18 is fixedly connected to the bottom surface of the first cylinder 17. The round block 16, the first cylinder 17, and the second cylinder 18 are concentrically placed. Two insertion rods 19 are respectively fixedly installed on both sides of the bottom surface of the first cylinder 17. The two insertion rods 19 are respectively located on both sides of the second cylinder 18. The insertion rods 19 can be inserted into the insertion holes 803. A threaded hole is opened at the bottom end of the second cylinder 18. The diameter of the round block 16 is larger than the diameter of the cylinder body 801. The diameter of the first cylinder 17 is larger than the inner diameter of the annular block 802. The diameter of the second cylinder 18 is smaller than the inner diameter of the annular block 802.

[0027] After the connecting piece is installed on the second cylinder 18, the connecting piece, the second cylinder 18, and the first cylinder 17 are inserted into the cylinder body 801, and the insertion rods 19 are inserted into the insertion holes 803. The round block 16 is located above the cylinder body 801. The bottom surface of the first cylinder 17 contacts the top surface of the annular block 802. The second cylinder 18 passes through the annular block 802. The bottom end part of the detecting piece exposes from the bottom end of the cylinder body 801. The cylinder body 801 and the detecting piece enter the soil under the hammering of the gravity block 5, and the bearing capacity test is carried out through the resistance during the entry.

[0028] Furthermore, the detection component described in this embodiment includes a metal probe rod 20. The bottom end of the metal probe rod 20 is a tip. A screw rod is fixedly installed at the top end of the metal probe rod 20, and the screw rod can be rotationally screwed into the threaded hole. The bottom end of the metal probe rod 20 being a tip makes it easier to insert into the soil. The screw rod is rotationally screwed into the threaded hole, and by controlling the screwing depth, the length change between the metal probe rod 20 and the second cylinder 18 is controlled, so that the bottom end of the metal probe rod 20 exposes the bottom end of the cylinder body 801, and the exposed length of the metal probe rod 20 can be adjusted as needed.

[0029] Furthermore, the detection component described in this embodiment includes a fixed rod 21. A cross-shaped shear rod 22 is fixedly installed at the bottom end of the fixed rod 21. Several shear teeth are fixedly installed at the bottom end of the cross-shaped shear rod 22. A screw rod is fixedly installed at the top end of the fixed rod 21, and the screw rod can be rotationally screwed into the threaded hole. A sensor for recording the shear strength is installed inside the cross-shaped shear rod 22. The screw rod is rotationally screwed into the threaded hole to adjust the length of the fixed rod 21, so that the cross-shaped shear rod 22 extends beyond the bottom end of the cylinder body 801, facilitating the shear strength test and the measurement of the torsional peak value.

[0030] Even further, a through groove is formed on the right side of the top surface of the horizontal plate 7 in this embodiment. A vertical support rod is slidably installed in the through groove, and a moving wheel is movably installed at the bottom end of the support rod. During the up and down adjustment of the horizontal plate 7, through the auxiliary support of the support rod, the horizontal plate 7 can be more evenly stressed, the structure can be more firm, and it can be more stable during use.
