Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering foundation sampling technology, and in particular to a sampling system for water conservancy engineering foundation testing. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an essential and precious resource for human production and life. In the current water conservancy project foundation testing, the sampling is generally carried out by staff using hand-held drilling equipment to drill holes in the foundation and take soil samples.

[0003] Chinese utility model patent ZL202420017398.9 discloses a sampling system for foundation testing in water conservancy projects. The system includes a base plate with a sampling mechanism installed at its top. The sampling mechanism is composed of vertical rods, a top plate, an electro-hydraulic rod, a positioning plate, a motor, a sleeve, threaded rods, and a clamping plate. A set of symmetrical vertical rods is welded to the top of the base plate, and the top plate is installed at the other end of each vertical rod. An electro-hydraulic rod is bolted to the top of the top plate, and a positioning plate is installed at the output end of the electro-hydraulic rod, with the vertical rods penetrating the positioning plate. A motor is bolted to the top of the positioning plate, and a sleeve is installed at the output end of the motor. A set of symmetrical threaded rods are threaded onto the sleeve's wall. The motor drives the sleeve, causing the sleeve to rotate the sampling tube, thus enabling sampling of the foundation in the water conservancy project.

[0004] However, when the above-mentioned device is used to sample the soil using a sampling tube, the soil sample is prone to slipping during the upward movement due to the lack of limiting components inside the sampling tube. Therefore, a sampling system for foundation testing of water conservancy projects is needed. Utility Model Content

[0005] In view of this, the present invention provides a sampling system for foundation testing of water conservancy projects, the main technical problem to be solved is that soil samples slip during the upward movement.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sampling system for foundation testing of water conservancy projects, comprising a base, a first motor fixedly connected to the top of the base, a first rotating column fixedly connected to the output end of the first motor, a first threaded rod and a second threaded rod rotatably connected to the top of the base, a first synchronous pulley fixedly connected to the outside of both the first threaded rod and the first rotating column, a first synchronous belt sleeved on the outside of the two first synchronous pulleys, and a second synchronous pulley fixedly connected to the outside of both the second threaded rod and the first rotating column, a second synchronous belt sleeved on the outside of the two second synchronous pulleys, and the outer surfaces of the first threaded rod and the second threaded rod... A movable plate is threadedly connected to the movable plate. A second motor is fixedly connected to the top of the movable plate. A second rotating column is fixedly connected to the output end of the second motor. A fixed tube is detachably connected to the bottom of the movable plate. A sampling tube is threadedly connected to the bottom of the fixed tube. A support base is fixedly connected to the inner wall of the sampling tube. A connecting half-ring is fixedly connected to the top of the support base. A connecting ring is rotatably connected to the inner wall of the connecting half-ring. A limit post is fixedly connected to the top of the connecting ring. A limit groove is formed at the bottom of the second rotating column, and the limit post is inserted into the inside of the limit groove. A limit ring is fixedly connected to the circumferential surface of the second rotating column. The position of the limit ring corresponds to that of the connecting half-ring. When the device is in use, the first motor is started to drive the first rotating column to rotate. This, in turn, utilizes the cooperation between the two first synchronous pulleys and the first synchronous belt, as well as the cooperation between the two second synchronous pulleys and the second synchronous belt, to drive the first threaded rod and the second threaded rod to rotate synchronously. This causes the moving plate to move downward, thereby moving the sampling tube downward through the fixed tube to collect soil samples. The soil enters the area above the connecting half-ring from the bottom of the sampling tube through the support base. Then, the second motor is started to drive the second rotating column to rotate. During rotation, the limiting ring is turned from one side of the connecting half-ring to the side where the soil enters, thus sealing off the area above the connecting half-ring and preventing the soil from slipping during the upward movement.

[0007] As a further description of the above technical solution: The top of the sampling tube has an installation groove, and a sealing ring is installed inside the installation groove, with the sealing ring fitting snugly against the bottom of the fixing tube. The sampling tube is connected to the fixing tube via the sealing ring, thereby improving the sealing performance of the connection between the sampling tube and the fixing tube.

[0008] As a further description of the above technical solution: the base has a positioning groove inside, and the positioning groove corresponds to the position of the sampling tube. The positioning groove facilitates the rapid positioning of the area to be sampled.

[0009] As a further description of the above technical solution: a fixing frame is fixedly connected to the top of the base, a handle is fixedly connected to the side surface of the fixing frame, and the first motor is located below the fixing frame. The handle facilitates movement of the device, thereby changing the sampling area.

[0010] As a further description of the above technical solution: a second fixing block is fixedly connected to the bottom of the movable plate, and a first fixing block is fixedly connected to the circumferential surface of the fixing tube, with the second fixing block engaging internally with the first fixing block. The engagement of the first and second fixing blocks enables rapid positioning of the fixing tube.

[0011] As a further description of the above technical solution: a groove is formed inside the movable plate, and a connecting shaft is slidably connected inside the groove. The connecting shaft slides inside the groove, thereby changing the length by which the connecting shaft moves out of the groove.

[0012] As a further description of the above technical solution: a compression spring is sleeved on the outside of the connecting shaft, and the compression spring is in contact with the end of the connecting shaft. When the connecting shaft compresses the compression spring, the compression spring will also generate a reaction force on the connecting shaft.

[0013] As a further description of the above technical solution: a connecting frame is fixedly connected to the end of the connecting shaft away from the moving plate. A limiting rod is fixedly connected inside the connecting frame, and the end of the limiting rod away from the connecting frame passes through the first fixing block and is inserted into the interior of the second fixing block. By using the limiting rod to pass through the first fixing block and connect to the interior of the second fixing block, the quick installation of the fixing tube can be achieved.

[0014] By employing the above technical solution, the sampling system for foundation testing of water conservancy projects of this utility model has at least the following beneficial effects:

[0015] 1. Compared with existing technologies, this sampling system for foundation testing in water conservancy projects, by setting up a second motor, a second rotating column, a limiting ring, and a support base, allows the first motor to be started during use, driving the first rotating column to rotate. This, in turn, utilizes the cooperation between the two first synchronous pulleys and the first synchronous belt, as well as the cooperation between the two second synchronous pulleys and the second synchronous belt, to drive the first threaded rod and the second threaded rod to rotate synchronously. This causes the moving plate to move downwards, thereby moving the sampling tube downwards through the fixed tube to collect soil samples. The soil enters the area above the connecting half-ring from the bottom of the sampling tube through the guide of the support base. Then, the second motor is started to drive the second rotating column to rotate. During rotation, the limiting ring is turned from one side of the connecting half-ring to the side where the soil enters, thus sealing off the area above the connecting half-ring and preventing the soil from slipping during the upward movement.

[0016] 2. Compared with the existing technology, the sampling system for foundation testing of water conservancy projects, by setting up a connecting frame, a limiting rod and a second fixing block, allows the fixing pipe to be installed by pulling the connecting frame outward, compressing the compression spring through the connecting shaft, which facilitates the removal of the limiting rod from the inside of the second fixing block. Then, the second fixing block at the bottom of the moving plate is engaged with the inside of the first fixing block outside the fixing pipe. Under the push of the reaction force of the compression spring, the limiting rod passes through the first fixing block and engages with the inside of the second fixing block, thereby realizing the rapid installation of the fixing pipe.

[0023] Reference Figure 1-4The sampling system for foundation testing of water conservancy projects provided by this utility model includes a base 1. A first motor 4 is fixedly connected to the top of the base 1. A first rotating column 5 is fixedly connected to the output end of the first motor 4. A first threaded rod 11 and a second threaded rod 12 are rotatably connected to the top of the base 1. First synchronous pulleys 6 are fixedly connected to the outside of both the first threaded rod 11 and the first rotating column 5. A first synchronous belt 8 is sleeved on the outside of the two first synchronous pulleys 6. Second synchronous pulleys 7 are fixedly connected to the outside of both the second threaded rod 12 and the first rotating column 5. A second synchronous belt 9 is sleeved on the outside of the two second synchronous pulleys 7. A moving plate 13 is threadedly connected to the outside of the first threaded rod 11 and the second threaded rod 12. A second motor 14 is fixedly connected to the top of the moving plate 13. The output end of the second motor 14 is fixed... A second rotating column 32 is connected to the bottom of the movable plate 13, and a fixed tube 15 is detachably connected to the bottom of the fixed tube 15. A sampling tube 16 is threadedly connected to the bottom of the fixed tube 15. A support base 21 is fixedly connected to the inner wall of the sampling tube 16. The support base 21 is inclined to facilitate the sliding of soil on its inner wall. A connecting half ring 22 is fixedly connected to the top of the support base 21. A connecting ring 23 is rotatably connected to the inner wall of the connecting half ring 22. A limiting column 24 is fixedly connected to the top of the connecting ring 23. A limiting groove 19 is opened at the bottom of the second rotating column 32, and the limiting column 24 is inserted into the limiting groove 19. A limiting ring 20 is fixedly connected to the circumferential surface of the second rotating column 32. The limiting ring 20 and the connecting half ring 22 are positioned correspondingly, and both the limiting ring 20 and the connecting half ring 22 are semi-circular, which facilitates soil entry when they overlap. When the device is in use, the first motor 4 is started to drive the first rotating column 5 to rotate. This, in turn, utilizes the cooperation between the two first synchronous pulleys 6 and the first synchronous belt 8, as well as the cooperation between the two second synchronous pulleys 7 and the second synchronous belt 9, to drive the first threaded rod 11 and the second threaded rod 12 to rotate synchronously. This causes the moving plate 13 to move downward, thereby driving the sampling tube 16 to move downward through the fixed tube 15 to collect soil samples. The soil enters the area above the connecting half-ring 22 from the bottom of the sampling tube 16 through the support base 21. Then, the second motor 14 is started to drive the second rotating column 32 to rotate. During rotation, the limiting ring 20 is turned from one side of the connecting half-ring 22 to the side where the soil enters, thus sealing off the area above the connecting half-ring 22 and preventing the soil from slipping during the upward movement.

[0024] The top of the sampling tube 16 has an installation groove 17, and a sealing ring 18 is installed inside the installation groove 17, with the sealing ring 18 fitting snugly against the bottom of the fixed tube 15. When the sampling tube 16 is connected to the fixed tube 15, the connection is made through the sealing ring 18, thereby improving the sealing performance of the connection between the sampling tube 16 and the fixed tube 15.

[0025] The base 1 has a positioning groove 10 inside, and the positioning groove 10 corresponds to the position of the sampling tube 16. The positioning groove 10 facilitates the quick positioning of the area to be sampled.

[0026] A mounting bracket 2 is fixedly connected to the top of the base 1, and a handle 3 is fixedly connected to the side surface of the mounting bracket 2. The first motor 4 is located below the mounting bracket 2. The handle 3 facilitates the movement of the device to change the sampling area.

[0027] A second fixing block 26 is fixedly connected to the bottom of the movable plate 13, and a first fixing block 25 is fixedly connected to the circumferential surface of the fixing tube 15, with the second fixing block 26 engaging internally with the first fixing block 25. The engagement of the first fixing block 25 and the second fixing block 26 enables the fixing tube 15 to be quickly positioned.

[0028] The movable plate 13 has a groove 27 inside, and a connecting shaft 28 is slidably connected inside the groove 27. The connecting shaft 28 slides inside the groove 27, thereby changing the length by which the connecting shaft 28 moves out of the groove 27.

[0029] A compression spring 29 is sleeved on the outside of the connecting shaft 28, and the compression spring 29 is in contact with the end of the connecting shaft 28. When the connecting shaft 28 compresses the compression spring 29, the compression spring 29 will also generate a reaction force on the connecting shaft 28.

[0030] A connecting frame 30 is fixedly connected to the end of the connecting shaft 28 away from the moving plate 13. A limiting rod 31 is fixedly connected inside the connecting frame 30, and the end of the limiting rod 31 away from the connecting frame 30 passes through the first fixing block 25 and is inserted into the interior of the second fixing block 26. By using the limiting rod 31 to pass through the first fixing block 25 and connect to the interior of the second fixing block 26, the quick installation of the fixing tube 15 can be achieved.

[0031] Working principle: When the device is in use, the first motor 4 is started to drive the first rotating column 5 to rotate. This, in turn, utilizes the cooperation between the two first synchronous pulleys 6 and the first synchronous belt 8, as well as the cooperation between the two second synchronous pulleys 7 and the second synchronous belt 9, to drive the first threaded rod 11 and the second threaded rod 12 to rotate synchronously. This causes the moving plate 13 to move downwards, thereby driving the sampling tube 16 downwards through the fixed tube 15 to collect soil samples. The soil enters the area above the connecting half-ring 22 from the bottom of the sampling tube 16, guided by the support base 21. Then, the second motor 14 is started to drive the second rotating column 32 to rotate. During rotation, the limiting ring 20 moves from the connecting half-ring... 22 is turned to the side where soil enters, thus sealing off the area above the connecting half-ring 22. This prevents the soil from slipping during the upward movement. When the fixing pipe 15 is installed, the connecting bracket 30 is pulled outward, and the compression spring 29 is compressed through the connecting shaft 28. This facilitates the removal of the limiting rod 31 from inside the second fixing block 26. Then, the second fixing block 26 at the bottom of the moving plate 13 is engaged with the inside of the first fixing block 25 outside the fixing pipe 15. Under the push of the reaction force of the compression spring 29, the limiting rod 31 passes through the first fixing block 25 and engages with the inside of the second fixing block 26, thereby achieving the rapid installation of the fixing pipe 15.
