Description

Technical Field

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

[0002] In a broad sense, water conservancy projects are projects built to prevent and control water-related disasters and to develop and utilize water resources. They include water-related projects in flood control, drainage, irrigation, water supply, hydropower generation, navigation, water resource protection, soil and water conservation, as well as aquaculture, tourism and ecological environment improvement projects.

[0003] Chinese patent discloses a soil and rock sampling device for water conservancy engineering testing (authorization announcement number CN219870352U). This patented technology can effectively and accurately determine the depth of the sampling device drilling into the soil and rock. The drill rod drives the spiral blade to rotate and transport the soil and rock into the sleeve, maintaining the original arrangement structure, which is convenient for layer marking and has strong practicality.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Although existing soil and rock sampling devices can use the drill rod to drive the spiral blade to rotate and transport soil and rock into the sleeve, maintaining the original arrangement structure and facilitating layer marking, the sampling sleeve is assembled with bolts when connected to the main body of the device. The operation process is relatively cumbersome and it is not convenient for workers to quickly disassemble and assemble, thus affecting the sampling efficiency of the device. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing soil and rock sampling device uses a spiral blade to transport soil and rock, and maintains its structure to facilitate layer marking. However, the connection between the sampling tube and the main body of the device requires bolt assembly, which is cumbersome to operate, affects the quick disassembly and assembly, and reduces the sampling efficiency. Therefore, we propose a soil and rock sampling device for water conservancy engineering testing.

[0006] To achieve the above objectives, this application adopts the following technical solution: a soil and rock sampling device for water conservancy engineering testing, comprising a base, an organism mounted on the top of the base, a first motor mounted on the top of the organism, a connecting block slidably connected inside the organism, a second motor mounted on the top of the connecting block, a drive rod mounted on the bottom of the connecting block, a fixing block fixedly connected to the surface of the drive rod, an extension block slidably connected to the bottom of the fixing block, a sampling cylinder fixedly connected to the bottom of the extension block, two connecting plates fixedly connected to the bottom of the fixing block, an insertion slot provided on one side of the connecting plate, two through slots provided on the top of the extension block, and two movable slots provided at one end of the extension block;

[0007] The movable groove is equipped with a fixing mechanism for fixing the position of the sampling cylinder.

[0008] Preferably, the fixing mechanism includes a baffle installed inside the movable groove, an adjusting rod slidably connected inside the baffle, an arc-shaped pushing block fixedly connected to one end of the adjusting rod, an arc-shaped force-bearing block abutting one side of the arc-shaped pushing block, an insertion rod fixedly connected to one side of the arc-shaped force-bearing block, and a through slot provided on one side of the inner cavity of the movable groove.

[0009] Preferably, a return spring is fixedly connected to one side of the arc-shaped force-bearing block, and one side of the return spring is fixedly connected to the inside of the movable groove.

[0010] Preferably, guide grooves are provided at the top and bottom of the inner cavity of the movable groove, and guide blocks are fixedly connected to the top and bottom of the arc-shaped force-bearing block.

[0011] Preferably, the bottom of the fixing block is provided with multiple positioning holes, and the top of the extension block is fixedly connected with multiple positioning rods.

[0012] Preferably, a slot is provided at the top of the inner cavity of the positioning hole, a thrust spring is fixedly connected inside the slot, and a thrust block is fixedly connected to the bottom of the thrust spring.

[0013] Preferably, sliding grooves are provided on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the thrust block.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the operator moves the adjusting rod to move the arc-shaped pushing block. During the movement, the arc-shaped pushing block releases the pressure on the arc-shaped force block. At this time, the return spring, due to its own elastic potential energy, pulls the arc-shaped force block back to its original position. The movement of the arc-shaped force block causes the insertion rod to be pulled out from the insertion slot, realizing the quick disassembly of the sampling tube, which facilitates the collection and analysis of soil and rock samples inside the sampling tube.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a soil and rock sampling device for water conservancy engineering testing, including a base 1, an organism 2 mounted on the top of the base 1, a first motor 3 mounted on the top of the organism 2, a connecting block 4 slidably connected inside the organism 2, a second motor 5 mounted on the top of the connecting block 4, a drive rod 6 mounted on the bottom of the connecting block 4, a fixing block 7 fixedly connected to the surface of the drive rod 6, an extension block 8 slidably connected to the bottom of the fixing block 7, a sampling cylinder 9 fixedly connected to the bottom of the extension block 8, two connecting plates 10 fixedly connected to the bottom of the fixing block 7, an insertion groove 11 opened on one side of the connecting plate 10, two through grooves 12 opened on the top of the extension block 8, two movable grooves 13 opened at one end of the extension block 8, a fixing mechanism for fixing the position of the sampling cylinder 9 installed inside the movable groove 13, the fixing mechanism including a baffle 14 installed inside the movable groove 13, and the baffle 14 sliding inside the baffle 14 An adjusting rod 15 is connected to the movable groove 13. One end of the adjusting rod 15 is fixedly connected to an arc-shaped pushing block 16. One side of the arc-shaped pushing block 16 abuts against an arc-shaped force-bearing block 17. One side of the arc-shaped force-bearing block 17 is fixedly connected to a plug-in rod 18. A through slot 19 is opened on one side of the inner cavity of the movable groove 13. A return spring 20 is fixedly connected to one side of the arc-shaped force-bearing block 17. One side of the return spring 20 is fixedly connected to the inside of the movable groove 13. When the operator moves the adjusting rod 15, it causes the arc-shaped pushing block 16 to move. During the movement, the arc-shaped pushing block 16 releases the pressure on the arc-shaped force-bearing block 17. At this time, the return spring 20, due to its own elastic potential energy, pulls the arc-shaped force-bearing block 17 to move back to its original position. The movement of the arc-shaped force-bearing block 17 causes the plug-in rod 18 to be pulled out from the inside of the plug-in slot 11, realizing the quick disassembly of the sampling tube 9, which facilitates the collection and analysis of soil and rock samples inside the sampling tube 9.

[0025] Reference Figure 5 As shown in this embodiment: guide grooves 21 are provided at the top and bottom of the inner cavity of the movable groove 13, and guide blocks 22 are fixedly connected to the top and bottom of the arc-shaped force block 17. By setting the guide grooves 21 and guide blocks 22, the movement of the arc-shaped force block 17 is guided and limited, which improves the stability of the arc-shaped force block 17 when it moves and avoids the phenomenon of the arc-shaped force block 17 deviating during the movement.

[0026] Reference Figure 2 and Figure 3 As shown in this embodiment: the bottom of the fixed block 7 is provided with multiple positioning holes 23, and the top of the extension block 8 is fixedly connected with multiple positioning rods 24. By setting the positioning holes 23 and positioning rods 24, the extension block 8 and the fixed block 7 can be quickly positioned and installed, which improves the convenience of installing the sampling tube 9 and increases the stability of the sampling tube 9 during use, avoiding the phenomenon of shaking of the sampling tube 9 during use.

[0027] Reference Figure 6 As shown in this embodiment: a slot 25 is provided at the top of the inner cavity of the positioning hole 23, and a thrust spring 26 is fixedly connected inside the slot 25. A thrust block 27 is fixedly connected to the bottom of the thrust spring 26. When the fixing block 7 and the extension block 8 are released from fixation, the cooperation between the thrust spring 26 and the thrust block 27 can give the positioning rod 24 a certain thrust, so that the positioning rod 24 drives the extension block 8 to move downward, thereby further facilitating the disassembly process of the sampling cylinder 9.

[0028] Reference Figure 6 As shown in this embodiment: both sides of the inner cavity of the slot 25 are provided with sliding grooves 28, and both sides of the thrust block 27 are fixedly connected with sliders 29. Through the cooperation of the sliding grooves 28 and the sliders 29, the thrust block 27 can be limited to prevent it from shaking or deviating during movement. This design improves the stability of the thrust block 27 sliding in the slot 25.

[0029] Working principle: The operator moves the adjusting rod 15, causing the arc-shaped pushing block 16 to move. During this movement, the arc-shaped pushing block 16 releases its pressure on the arc-shaped force-bearing block 17. At this time, the return spring 20, due to its elastic potential energy, pulls the arc-shaped force-bearing block 17 back to its original position. The movement of the arc-shaped force-bearing block 17 causes the insertion rod 18 to be pulled out from the insertion slot 11, achieving quick disassembly of the sampling cylinder 9. This facilitates the collection and analysis of soil and rock samples inside the sampling cylinder 9. The guide groove 21 and guide block 22 guide and limit the movement of the arc-shaped force-bearing block 17, improving its stability and preventing deviation during movement. By setting the positioning hole 23 and the positioning rod 24, the extension block 8 and the fixed block 7 can be quickly positioned and installed, which improves the convenience of the sampling cylinder 9 installation and increases the stability of the sampling cylinder 9 during use, avoiding the phenomenon of shaking during the use of the sampling cylinder 9. When the fixed block 7 and the extension block 8 are released from the fixation, the cooperation of the thrust spring 26 and the thrust block 27 can give the positioning rod 24 a certain thrust, so that the positioning rod 24 drives the extension block 8 to move downward, thereby further facilitating the disassembly process of the sampling cylinder 9. Through the cooperation of the sliding groove 28 and the slider 29, the thrust block 27 can be limited to prevent it from shaking or deviating during the movement. This design improves the stability of the thrust block 27 sliding in the groove 25.
