[0002] A water conservancy and hydropower project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, and is also called a water project. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. Before the current water conservancy and hydropower projects are constructed, it is usually necessary to sample and detect the foundation rock and soil.

[0003] At present, the main method for measuring soil bulk density is the undisturbed soil sampling tube method. The undisturbed soil sampling tube method can obtain soil samples of multiple soil layers at one time, and the soil sampling efficiency is relatively high. However, it is difficult to take out the stored soil samples. Usually, it is necessary to manually continuously knock the sampling tube to take out the soil samples, with a large labor intensity and low work efficiency.

[0004] Therefore, in view of the above status quo, there is an urgent need to develop a device for sampling foundation rock and soil in the construction of water conservancy and hydropower projects to overcome the deficiencies in current practical applications. Content of the Utility Model

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The following describes the specific implementation of the present utility model in detail in combination with specific embodiments.

[0025] As Figures 1-4 shown, an embodiment of the present utility model provides a device for sampling foundation rock and soil in the construction of water conservancy and hydropower projects, including a base 1, a fixed seat 2 fixedly connected to the base 1, a receiving plate 3 rotatably connected to the fixed seat 2, a hydraulic telescopic rod 4 is cooperatively arranged between the receiving plate 3 and the base 1, and both ends of the hydraulic telescopic rod 4 are respectively hinged to the base 1 and the receiving plate 3. An elevating device 6 is fixedly arranged on the side surface of the receiving plate 3, a second motor 8 is fixedly arranged on the elevating device 6, a connecting pipe 7 is fixedly connected to the driving end of the second motor 8, a sampling pipe 9 is cooperatively connected to the lower end of the connecting pipe 7, the lower end of the sampling pipe 9 penetrates through the base 1, and a plurality of clamping holes 10 are opened on both the sampling pipe 9 and the connecting pipe 7. A connecting component 11 is cooperatively arranged in the connecting pipe 7, and the connecting pipe 7 and the sampling pipe 9 are fixedly connected by means of the cooperation between the connecting component 11 and the clamping holes 10. A clamping component 5 is cooperatively arranged on the receiving plate 3, and the clamping component 5 is used for fixedly clamping the clamping holes 10.

[0026] It can be understood that when a single sampling pipe 9 cannot meet the sampling depth, multiple sampling pipes 9 can be connected end to end in sequence to extend the sampling depth. The multiple sampling pipes 9 can be fixed by means of threaded connection, but only the lowermost sampling pipe 9 is used for sampling each time. This method belongs to the prior art and will not be described in detail here.

[0027] As Figure 1 shown, the clamping component 5 includes a threaded rotating rod 51, a first motor 52, a clamping plate 53 and a clamping groove 54; two symmetric first motors 52 are fixedly connected to one end surface of the receiving plate 3 close to the hydraulic telescopic rod 4, the driving ends of the first motors 52 are both fixedly connected with threaded rotating rods 51, two clamping plates 53 symmetrically distributed about the connecting pipe 7 are threadedly connected between the two threaded rotating rods 51, clamping grooves 54 are opened at one ends of the two clamping plates 53 close to each other, and the radius of the clamping groove 54 is the same as the outer diameter of the sampling pipe 9.

[0028] Furthermore, two threads with opposite directions are opened on the threaded rotating rod 51 and are respectively threadedly connected to the corresponding two clamping plates 53.

[0029] In specific applications, when the sampling pipe 9 needs to be stationary, control the two first motors 52 to start synchronously, then the first motors 52 drive the threaded rotating rods 51 to rotate, and then the threaded rotating rods 51 drive the two clamping plates 53 to approach each other until the clamping grooves 54 are closely attached to the outer wall of the sampling pipe 9, fixedly clamping the sampling pipe 9, thereby restricting the movement of the sampling pipe 9.

[0030] As Figure 2 and Figure 3As shown, the connection component 11 includes a fixing plate 1101, a third motor 1102, a fixed shaft 1103, a rotating plate 1104, an arc-shaped groove 1106, a sticking block 1107, and a chuck 1109; a fixing plate 1101 is fixedly connected to the inner wall of the connecting pipe 7. The lower end of the fixing plate 1101 is fixedly connected to a third motor 1102. The driving end of the third motor 1102 is fixedly connected to a fixed shaft 1103. The outer wall of the bottom end of the fixed shaft 1103 is fixedly sleeved with a rotating plate 1104. A plurality of arc-shaped grooves 1106 evenly distributed in the circumferential direction are formed on the rotating plate 1104. A chuck 1109 is slidably connected to the inner wall of the card hole 10 on the connecting pipe 7. One end of each chuck 1109 is fixedly connected to a sticking block 1107. A fixing rod (not shown in the figure) is fixedly connected to the lower end of each sticking block 1107. The fixing rod abuts against the inner wall of the arc-shaped groove 1106, and the lower end of the sticking block 1107 abuts against the rotating plate 1104.

[0031] Further, a fixed ring plate 1105 is fixedly connected to the inner wall of the connecting pipe 7. The fixed ring plate 1105 is not in contact with the fixed shaft 1103. A plurality of limiting grooves 1108 evenly distributed in the circumferential direction are formed on the fixed ring plate 1105. The limiting grooves 1108 correspond to the sticking blocks 1107 one by one. The sticking blocks 1107 are slidably connected to the limiting grooves 1108.

[0032] Further, the ends of the chuck 1109 away from the fixed shaft 1103 and the ends of the sticking block 1107 away from the fixed shaft 1103 are both arc-shaped surfaces. The radius of the arc-shaped surface of the chuck 1109 is equal to the outer wall radius of the sampling tube 9, and the radius of the arc-shaped surface of the sticking block 1107 is equal to the inner wall radius of the connecting pipe 7, so as to ensure that the sticking block 1107 can fit the inner wall of the connecting pipe 7 and the chuck 1109 can fit the outer wall of the sampling tube 9 without protruding.

[0033] Further, the distance between the inner wall of the connecting pipe 7 and the outer wall of the sampling tube 9 is equal to the length of the chuck 1109, so as to ensure that when the sticking block 1107 fits the inner wall of the connecting pipe 7, the chuck 1109 can fit the outer wall of the sampling tube 9 without protruding.

[0034] In specific application, control the fixed shaft 1103 to start. Then the fixed shaft 1103 drives the rotating plate 1104 to rotate. After that, the fixed shaft 1103 drives the arc-shaped groove 1106 to rotate around the axis of the fixed shaft 1103. Then the sticking blocks 1107 are driven to approach or separate from each other through the fixing rods. The sticking blocks 1107 drive the plurality of chucks 1109 to approach or separate from the fixed shaft 1103, so that the chucks 1109 are disengaged from the card holes 10 on the sampling tube 9 or inserted into the card holes 10 on the sampling tube 9.

[0035] In the embodiment of the present utility model, the connecting pipe 7 and the sampling pipe 9 are fixedly connected through the connecting component 11. The connecting pipe 7 is driven to rotate by the second motor 8, and then the connecting pipe 7 drives the sampling pipe 9 to rotate. The lifting device 6 synchronously drives the second motor 8 to descend, thereby driving the sampling pipe 9 to descend, so as to perform geotechnical drilling sampling. After sampling, the sampling pipe 9 is driven by the lifting device 6 to rise and reset. Then, the sampling pipe 9 is fixedly clamped by the clamping component 5. Subsequently, the hydraulic telescopic rod 4 is controlled to drive the bearing plate 3 to rotate until the bearing plate 3 is in a horizontal state. Then, the third motor 1102 is controlled to disengage the chuck 1109 from the card hole 10 on the sampling pipe 9. Then, the lifting device 6 is controlled to move, and the lifting device 6 drives the connecting pipe 7 to push the soil sample in the sampling pipe 9, thereby pushing out the soil sample. The labor intensity is small and the work efficiency is high.

[0036] The working principle of the present utility model is as follows: Control the fixed shaft 1103 to start, and then the fixed shaft 1103 drives the rotating plate 1104 to rotate. After that, the fixed shaft 1103 drives the arc-shaped groove 1106 to rotate around the axis line of the fixed shaft 1103. Then, the fixed rod drives the sticking blocks 1107 to move away from each other, and the sticking blocks 1107 drive the plurality of clamping heads 1109 to move away from the fixed shaft 1103, so that the clamping heads 1109 are inserted into the clamping holes 10 on the sampling tube 9, thereby fixedly connecting the connecting tube 7 and the sampling tube 9. After that, the second motor 8 drives the connecting tube 7 to rotate, and then the connecting tube 7 drives the sampling tube 9 to rotate. The lifting device 6 synchronously drives the second motor 8 to descend, thereby driving the sampling tube 9 to descend, so as to perform geotechnical drilling sampling. After sampling, the lifting device 6 drives the sampling tube 9 to rise and reset. Then, the sampling tube 9 is fixedly clamped by the clamping assembly 5. Subsequently, control the hydraulic telescopic rod 4 to drive the bearing plate 3 to rotate until the bearing plate 3 is in a horizontal state. After that, control the third motor 1102 to make the clamping heads 1109 disengage from the clamping holes 10 on the sampling tube 9. Then, control the movement of the lifting device 6, and the lifting device 6 drives the connecting tube 7 to push the soil sample in the sampling tube 9, so as to push out the soil sample. When it is necessary to continue to increase the sampling depth, sampling tubes 9 need to be gradually increased during the drilling stage. Control the third motor 1102 to reset so that the clamping heads 1109 disengage from the clamping holes 10 on the sampling tube 9. Then, drive the connecting tube 7 to rise by the lifting device 6. Then, thread-connect a new sampling tube 9 to the upper end of the sampling tube 9. After that, fixedly connect the connecting tube 7 and the newly added sampling tube 9 through the connecting assembly 11. During sampling, it is necessary for the operator to use tools to fix the second sampling tube 9. Then, the second motor 8 drives the first sampling tube 9 to rotate through the connecting tube 7, and the lifting device 6 synchronously drives the connecting tube 7 to rise. The first sampling tube 9 is separated from the second sampling tube 9. Then, control the third motor 1102 to drive the clamping heads 1109 to disengage from the clamping holes 10 on the first sampling tube 9. Then, the lifting device 6 descends. Subsequently, the connecting tube 7 fixes the remaining first sampling tube 9 through the connecting assembly 11. Then, the lifting device 6 drives the sampling tube 9 to rise. Similarly, the operator fixes the remaining second sampling tube 9. The above steps are cyclically executed until the last sampling tube 9.

[0037] The circuits, electronic components and modules involved are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve the improvement of software and methods either.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
