Description

Technical Field

[0001] This utility model relates to the field of soil and rock sampling technology, specifically a soil and rock sampling device for the foundation of water conservancy and hydropower engineering construction. Background Technology

[0002] Water conservancy and hydropower projects are important public welfare projects, which are various projects aimed at flood control, irrigation, power generation, and water supply. When surveying water conservancy and hydropower projects, it is necessary to sample and analyze the foundation soil and rock to obtain key information such as the physical and mechanical properties and chemical composition of the foundation soil and rock, so as to provide an important basis for project design and construction.

[0003] Currently, patent CN208333936U discloses a soil and rock sampling device. Its advantages include preventing soil and rock samples from being contaminated during lifting and ensuring good preservation during transportation, preventing spillage and improving sampling efficiency. A sealing tube is fitted onto the sampling tube, and an inlet is formed on the outer wall of the sealing tube along its length and at the same height as the sampling outlet. The sampling tube and the sealing tube can rotate relative to each other axially, allowing the inlet and sampling outlet to either completely overlap or completely offset. Before sampling into the soil layer, rotate the sampling tube or sealing tube to completely offset the sampling port and inlet. Insert the device into the soil layer to the desired sampling location, then rotate the sampling tube or sealing tube to completely align the sampling port and inlet. This allows the soil to flow into the sampling tube through the sampling port and inlet. After the soil sample is collected, rotate the sampling tube or sealing tube to completely offset the sampling port and inlet, and then remove the device from the soil layer. During the upward removal of the device, no more soil from the soil layer will enter the sampling tube, preventing contamination of the soil sample and improving sampling efficiency.

[0004] However, the following problems still exist in the use of current soil and rock sampling devices:

[0005] The aforementioned device adopts an integrated structure. In order to ensure normal rotation and sampling of rock mass, the length of the sampling handle is set to be relatively long. As a result, it requires a large area of ​​space during handling and carrying, which is very inconvenient. Moreover, after sampling, the moist soil tends to adhere to the inside of the sampling tube, making it impossible to fully and quickly discharge the sample. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a soil and rock sampling device for the foundation of water conservancy and hydropower engineering construction. By setting the moving rod as a telescopic structure, the length can be reduced to decrease the footprint when carried, and the sampled rock mass can be removed by moving the bulldozer blade.

[0007] This utility model provides the following technical solution: a soil and rock sampling device for the foundation of a water conservancy and hydropower project, including a sampling tube with a soil breaking knife set at an equal angle at its lower end and a fixed rod set at the upper end of the sampling tube; a telescopic component is set inside the fixed rod, and a rotating handle is set at the upper end of the telescopic component; a measuring component is fitted to the outside of the fixed rod, and a fixing screw is passed through the upper end of the fixed rod.

[0008] Furthermore, the telescopic component includes a limiting slider and a moving rod. The limiting slider is slidably connected to the fixed rod through a groove on the fixed rod, and the moving rod is connected to the limiting slider and slidably connected to the fixed rod. With the above structure, the movement range of the moving rod can be limited under the action of the limiting slider.

[0009] Furthermore, the telescopic assembly also includes a connecting screw and a bulldozer plate, and the moving rod is connected to the moving rod through a threaded hole at its lower end. The lower end of the connecting screw is fixedly connected to the upper end of the bulldozer plate. Through the above structure, it is convenient for the connecting screw to install and fix the bulldozer plate and the moving rod.

[0010] Furthermore, the bulldozer blade is configured as a circular plate structure, and the inner surface of the bulldozer blade and the sampling cylinder are in close contact with each other. The inner surface of the sampling cylinder is configured to be smooth. Through the above structure, it is easy to reduce the friction between the bulldozer blade and the sampling cylinder.

[0011] Furthermore, two rotating handles are symmetrically arranged about the middle of the moving rod, and the outside of the rotating handles is provided with a soft rubber layer with a matte surface. With the above structure, it is convenient to rotate the moving rod and the fixed rod by rotating the handles.

[0012] Furthermore, the measuring component includes a movable ring plate and a support rod, and the movable ring plate has a through hole starting from the middle position. The movable ring plate and the fixed rod are slidably connected, and the lower end of the movable ring plate is connected to the support rod. With the above structure, the sampling depth of the sampling tube can be intuitively viewed through the movable ring plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This soil and rock sampling device for the construction site of a water conservancy and hydropower project allows for the extension or retraction of a movable rod, reducing the area occupied during transport while ensuring normal use. During retraction, the rod simultaneously moves a bulldozer plate, pushing the soil and rock sampled from the sampling tube out, preventing insufficient material from being dispensed due to soil moisture. The movable ring plate and support rod allow for direct monitoring of the sampling depth, making the process more convenient and efficient, and effectively ensuring sampling accuracy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a soil and rock sampling device for foundation construction in water conservancy and hydropower projects, comprising a sampling cylinder 1, with a soil-breaking blade 2 set at an equal angle at its lower end, and a fixed rod 3 set at the upper end of the sampling cylinder 1; a telescopic component 4 is provided inside the fixed rod 3, and a rotating handle 5 is provided at the upper end of the telescopic component 4; a measuring component 6 is fitted to the outside of the fixed rod 3; the telescopic component 4 includes a limiting slider 401 and a moving rod 402, and the limiting slider 401 is slidably connected to the fixed rod 3 through a groove opened on the fixed rod 3. Furthermore, the moving rod 402 is connected to the limiting slider 401, and the moving rod 402 is slidably connected to the fixed rod 3; there are two rotating handles 5 symmetrically arranged about the middle of the moving rod 402, and the outside of the rotating handles 5 is provided with a soft rubber layer with a matte surface; the measuring component 6 includes a moving ring plate 601 and a support rod 602, and the moving ring plate 601 has a through hole starting from the middle position, the moving ring plate 601 is slidably connected to the fixed rod 3, and the lower end of the moving ring plate 601 is connected to the support rod 602;

[0024] When sampling the foundation soil and rock of a water conservancy and hydropower project is required, the sampling cylinder 1 is placed vertically, meaning the soil-breaking blade 2 installed at the lower end of the sampling cylinder 1 begins to contact the soil and rock. Then, the rotating handle 5 is pressed and turned. Because the rotating handle 5 is installed at the upper end of the moving rod 402, and the moving rod 402 is connected to the fixed rod 3 via a fixing screw 7 (the fixing screw 7 passes through the fixed rod 3 and is connected to the moving rod 402 through a threaded hole), the fixed rod 3 begins to rotate. Since the sampling cylinder 1 is installed at the lower end of the fixed rod 3, the sampling cylinder 1 also begins to rotate. As the sampling cylinder 1 rotates, it begins to enter the soil under the action of pressing and rotating, thus achieving the purpose of soil sampling. During this process, as the soil-breaking blade 2 comes into contact with the soil and rock, the lower end of the support rod 602 also begins to come into contact with the soil and rock (when the support rod 602 is not under force, the lower end of the support rod 602 and the lower end of the soil-breaking blade 2 are on the same horizontal plane). At this time, as the sampling cylinder 1 enters the soil and rock, the moving ring plate 601 begins to slide outside the fixed rod 3. Since the outer surface of the fixed rod 3 is set with a scale, by moving the moving ring plate 601 to different scale positions, the depth of the sampling cylinder 1 entering the soil can be visually observed, ensuring that the sampled soil is the soil at the required depth.

[0025] A fixing screw 7 is provided through the upper end of the fixed rod 3; the telescopic assembly 4 also includes a connecting screw 403 and a bulldozer plate 404, and the moving rod 402 is connected to the moving rod 402 through a threaded hole at its lower end, and the lower end of the connecting screw 403 is fixedly connected to the upper end of the bulldozer plate 404; the bulldozer plate 404 is configured as a circular plate structure, and the bulldozer plate 404 is in contact with the inner surface of the sampling cylinder 1, and the inner surface of the sampling cylinder 1 is configured to be smooth;

[0026] When soil is sampled into sampling cylinder 1, pull and rotate handle 5. Rotating handle 5 will move sampling cylinder 1 upwards, allowing it to be removed from the soil and rock. Then, rotate fixing screw 7, causing it to move away from fixing rod 3 until it is no longer connected to the threaded hole on moving rod 402. Then, push moving rod 402 towards fixing rod 3. At this point, limiting slider 401 begins to slide within the groove on fixing rod 3. Because the lower end of moving rod 402 is connected to bulldozer plate 404 via connecting screw 403, bulldozer plate 404 is also pushed downwards, thus removing the sampled rock mass from sampling cylinder 1. When it is necessary to clean the interior of sampling cylinder 1... When thoroughly cleaning, rotate the bulldozer plate 404 (the lower end of the bulldozer plate 404 has an arc-shaped groove for rotation). Because the upper end of the bulldozer plate 404 has a connecting screw 403, the connecting screw 403 will start to move away from the moving rod 402 (the moving rod 402 is connected to the connecting screw 403 through a threaded hole at its lower end). At this time, the moving rod 402 can be retracted into the fixed rod 3, thereby reducing the overall length of the sampling device and making it easier to carry. When using it again, pull the moving rod 402 to the uppermost position inside the fixed rod 3, and then fix it with the fixing screw 7 to increase the length of the device and avoid the need to bend over and rotate it when sampling due to the short length of the device, effectively ensuring the comfort of use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
