Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rock and soil sampling device for water conservancy project detection. Background Art
[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and allocate water to meet the needs of people's lives and production for water resources.
[0003] The structure and properties of rock and soil have an important influence on bearing capacity. Sampling and analysis of rock and soil is an essential and important work link before the construction of water conservancy projects. Rock and soil sampling mainly uses sampling devices to extract test soil to understand the properties of its base.
[0004] The existing rock and soil sampling devices are large in size and take up a lot of space during carrying, which makes them inconvenient to carry. After collecting soil samples, most of the existing rock and soil sampling devices use tools to push the soil samples out of the sampling tubes for testing, which results in a large error between the actual sampling depth of the rock and soil and the theoretical sampling depth that needs to be tested. Utility Model Content
[0005] The main purpose of the utility model is to provide a rock and soil sampling device for water conservancy project inspection. Through a first sampling tube and a second sampling tube, the first sampling tube is taken out from the second sampling tube by a pull ring. The setting of the second sampling tube avoids the movement of the sample soil position in the first sampling tube when the sampling device is taken out from the rock and soil. The setting of the window facilitates the collection of sample soil, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a rock and soil sampling device for water conservancy project detection, comprising:
[0007] A first sampling tube, one end of which is set as an opening, and an end away from the opening is provided with a first sawtooth, an array of windows is provided around the periphery of the first sampling tube, and a scale mark is engraved on one side of the periphery of the first sampling tube;
[0008] The second sampling tube is sleeved on the periphery of the first sampling tube, the second sampling tube is provided with second saw teeth at one end close to the first saw teeth, and a thread is provided at the periphery of one end away from the first saw teeth;
[0009] A screw rod is arranged at the top of the second sampling tube, one end of the screw rod is fixedly connected to the rotating handle, and the other end is fixedly connected to the top cover, the outer edge of the top cover protrudes away from the screw rod, and a first thread groove is arranged around the inner circumference, and the top cover is connected to the top end of the second sampling tube through the thread matching with the first thread groove.
[0010] On the basis of the above technical solution, the present invention can also be improved as follows.
[0011] Furthermore, the rock and soil sampling device for water conservancy project inspection also includes a support assembly, which includes a support plate and a support rod. A screw nut is fixedly installed at the center of the support plate, and support rods are arranged in a circular array on the outer edge of the support plate.
[0012] Furthermore, the screw nut is sleeved on the outer periphery of the screw.
[0013] Furthermore, a hole is provided at one end of the support rod close to the support plate, and a second thread groove is provided at a corresponding position on the outer edge of the support plate. The bolt passes through the hole and is threadedly connected to the second thread groove.
[0014] Furthermore, a pin is provided at one end of the support rod away from the support plate.
[0015] Furthermore, a pull ring is provided at one end of the first sampling tube away from the first sawtooth, and the pull ring is rotatably connected to one side of the first sampling tube through a hinge.
[0016] The beneficial effects of the utility model are as follows: the utility model provides a rock and soil sampling device for water conservancy project detection, which has the following advantages:
[0017] 1. The utility model provides a first sampling tube and a second sampling tube, and the first sampling tube is taken out from the second sampling tube by a pull ring.

[0030] A first sampling tube 1 is provided with an opening at one end, a first sawtooth 9 is provided at the end away from the opening, windows 5 are provided in an array around the periphery of the first sampling tube 1, a scale mark 4 is engraved on one side of the periphery of the first sampling tube 1, a pull ring 2 is provided at the end of the first sampling tube 1 away from the first sawtooth 9, the pull ring 2 is rotatably connected to one side of the first sampling tube 1 through a hinge 3, after sampling, the first sampling tube 1 is taken out of the second sampling tube 7 through the pull ring 2, the setting of the window 5 facilitates the collection of sample soil, avoids the error between the sampling depth and the detected sample soil depth caused by the process of pushing the sample soil out of the sampling tube, solves the problem that there is a large error between the actual sampling depth of rock and soil and the theoretical sampling depth of rock and soil that needs to be detected in the existing sampling device, and the setting of the scale mark 4 facilitates the checking of the rock and soil sampling depth;
[0031] The second sampling tube 7 is sleeved on the outer periphery of the first sampling tube 1. The second sampling tube 7 has the same length as the first sampling tube 1. The second sampling tube 7 is provided with a second sawtooth 6 at one end close to the first sawtooth 9, and a thread 8 is provided at the outer periphery of the end away from the first sawtooth 9. The arrangement of the second sampling tube 7 avoids the phenomenon that the position of the sample soil in the first sampling tube 1 moves when the sampling device is taken out of the rock and soil, thereby avoiding the error between the sampling depth and the detection depth;
[0032] The screw rod 13 is arranged at the top of the second sampling tube 7. One end of the screw rod 13 is fixedly connected to the rotating handle 12, and the other end is fixedly connected to the top cover 16. The outer edge of the top cover 16 protrudes away from the screw rod 13, and a first thread groove 19 is arranged around the inner circumference. The top cover 16 is connected to the top of the second sampling tube 7 through the thread 8 cooperating with the first thread groove 19. Before sampling, the second sampling tube 7 is fixed to the bottom of the top cover 16. During the sampling process, the second sampling tube 7 is rotated by rotating the rotating handle 12, so that the second sampling tube 7 and the first sampling tube 1 enter the rock and soil for sampling.
[0033] Embodiment 2
[0034] In order to further stabilize the device, Figure 2-3As shown, based on the first embodiment, the following improvements are made on the screw rod 13:
[0035] In the present embodiment, the geotechnical sampling device for water conservancy engineering detection further includes a support assembly 20, which includes a support plate 10 and a support rod 14. A screw nut 15 is fixedly installed at the center of the support plate 10. The support rod 14 is arranged in a circular array on the outer edge of the support plate 10. The support rod 14 is provided with a hole near one end of the support plate 10. A second thread groove 17 is arranged at a corresponding position on the outer edge of the support plate 10. A bolt 18 is passed through the hole and is threadedly connected with the second thread groove 17. The support rod 14 is fixed by the bolt 18. A pin 11 is arranged at one end of the support rod 14 away from the support plate 10. Before sampling, the support plate 10 is parallel to the ground by adjusting the positions of the multiple support rods 14. The screw 13 is sleeved in the screw nut 15. The screw nut 15 limits the position of the screw 13 in the horizontal direction, thereby ensuring that the first sampling tube 1 and the second sampling tube 7 are always parallel to the ground during the sampling process, thereby solving the problem of error between the sample soil depth and the actual depth caused by the first sampling tube 1 not sampling vertically.
[0036] Here’s how it works:
[0037] Before sampling, the positions of the plurality of support rods 14 are adjusted to make the support plate 10 parallel to the ground, the screw rod 13 is inserted into the screw rod nut 15, the bottom end of the screw rod 13 is fixedly connected with the top cover 16, and the second sampling tube 7 is fixed to the bottom of the top cover 16. During the sampling process, the second sampling tube 7 is rotated by rotating the rotating handle 12, so that the second sampling tube 7 and the first sampling tube 1 enter the rock and soil for sampling. After sampling, the second sampling tube 7 and the first sampling tube 1 are taken out of the rock and soil, and the second sampling tube 7 is set. The phenomenon of movement of the soil sample position in the first sampling tube 1 when the sampling device is taken out from the rock and soil is avoided. The first sampling tube 1 is taken out from the second sampling tube 7 by the pull ring 2. The setting of the window 5 facilitates the collection of soil samples and avoids the error between the sampling depth and the detected soil sample depth caused by the process of pushing the soil sample out of the sampling tube. The problem of large error between the actual soil sampling depth and the theoretical soil sampling depth required to be detected in the existing sampling device is solved. The setting of the scale mark 4 facilitates the checking of the soil sampling depth.
