[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] The present utility model provides a technical solution, as Figures 1 - 3 shown; a layered water-stop detection cylinder for geological exploration, including a sampling sleeve 1, further including: a sampling port 11, evenly distributed on the outer surface of the sampling sleeve 1 and distributed in a ring shape, with annular baffles 111 provided at its upper and lower ends, a fixed connecting rod 112 installed between the two annular baffles, an outer filter screen 113 provided on the outer side between the two annular baffles, an inner filter screen 114 provided on the inner side between the two annular baffles, and filter cotton 115 provided between the outer filter screen 113 and the inner filter screen 114.

[0034] In the embodiment of the present utility model, by setting the sampling port 11 and arranging it in a ring shape on the sampling sleeve 1, the water collection area can be increased, enabling the moisture in the soil to efficiently penetrate into the sampling sleeve 1, thereby avoiding the problem of blockage of the water collection holes.

[0035] In the embodiment of the present utility model, by setting the outer filter screen 113, the inner filter screen 114 and the filter cotton 115, the permeated moisture can be filtered to reduce the sediment content in the sample and ensure accurate sampling of the sample.

[0036] In the embodiment of the present utility model, by setting the fixed connecting rod 112, the overall stability of the sampling sleeve 1 can be ensured, enabling it to be stably inserted into the soil, and then performing stratified sampling of the soil.

[0037] The plugging sampling mechanism 2 is arranged inside the sampling sleeve 1 and includes: a plugging sleeve 21 arranged on the upper and lower sides of the sampling port 11, in sliding contact with the annular baffle 111 and located inside the sampling sleeve 1, with an adjusting baffle 211 arranged at one end of its outer surface, and the adjusting baffle 211 is threadedly connected to the sampling sleeve 1; an annular sealing ring 22 sleeved on the outer surface of the plugging sleeve 21, in sliding connection and fixedly connected to the annular baffle 111.

[0038] In the embodiment of the present utility model, by setting the plugging sleeve 21, through the elasticity of the annular sealing ring 22, the two plugging sleeves 21 can slide on the upper and lower sides inside the sampling port 11. Furthermore, the sampling port 11 can be plugged by the contact extrusion of the two plugging sleeves 21, thereby avoiding the mixing of the sample water permeating from multiple sampling ports 11, realizing stratified sampling and ensuring the accuracy of the sample.

[0039] In the embodiment of the present utility model, the annular sealing ring 22 is a rubber expansion sealing ring. It wraps the plugging sleeve 21 with elasticity to keep the space between the plugging sleeve 21 and the sampling sleeve 1 airtight. Secondly, by connecting with the annular baffle 111, it is fixed to avoid the leakage of sample water into the gap between the plugging sleeve 21 and the sampling sleeve 1, thereby avoiding the situation of sample cross - contamination.

[0040] Synchronization sleeves 23 are installed on the adjusting baffles 211 on the upper side of the sampling ports 11 and are evenly distributed; synchronization sliding rods 24 are installed on the adjusting baffles 211 on the lower side of the sampling ports 11, are in corresponding positions with the synchronization sleeves 23, and are slidably inserted into the synchronization sleeves 23; synchronization rod grooves 25 are opened at the upper ends of the plugging sleeves 21 on the lower side of the sampling ports 11 and are evenly distributed; synchronization connecting rods 26 are installed at the lower ends of the plugging sleeves 21 on the upper side of the sampling ports 11, are in corresponding positions with the synchronization rod grooves 25, and are slidably inserted into the synchronization rod grooves 25; adjusting handles 27 are installed above the adjusting baffles 211 above the uppermost sampling port 11, and their upper ends extend out of the sampling sleeve 1.

[0041] In the embodiment of the present utility model, through the sliding cooperation between the synchronization sleeves 23 and the synchronization sliding rods 24, the plugging sleeves 21 between the two sampling ports 11 can be rotated synchronously. By using the sliding cooperation between the synchronization rod grooves 25 and the synchronization connecting rods 26, the two plugging sleeves 21 on both sides of the sampling port 11 can be rotated synchronously, so that the staff can adjust the opening and closing of the sampling port 11, facilitating the sampling work of samples at different heights and avoiding contamination during the sampling process.

[0042] Sampling tubes 28 are inserted into the sampling sleeves 1 and are located inside the plugging sleeves 21. Lower pistons 281 are installed at their lower ends, upper pistons 282 are installed at their upper ends, and a number of sampling holes 283 are opened at the lower ends of their outer side surfaces and are evenly distributed. Connecting tubes 284 are installed at their upper ends, external connecting tubes 285 are installed at the upper ends of the connecting tubes 284, and the upper ends of the external connecting tubes 285 extend out of the sampling sleeve 1.

[0043] In the embodiment of the present utility model, by using the upper pistons 282 and the lower pistons 281, they can be inserted into the plugging sleeves 21 to block the upper and lower ends of the plugging sleeves 21, thereby separating the sampling position from the internal space of the sampling sleeve 1, avoiding contamination of the sample during the sampling process, ensuring the accuracy of sample sampling, and enabling layered sampling of the sample at the same time.

[0044] In the embodiment of the present utility model, the connecting tubes 284, the external tubes 285, and the sampling tubes 28 are docked by means of threaded connection, enabling them to be assembled into a long sampling pipeline for extracting and sampling water samples in the soil.

[0045] In the present utility model, the plugging sleeves 21 on the upper and lower sides of the sampling ports 11 are threadedly connected to the sampling sleeves 1 by the adjusting baffles 211, so that they move synchronously towards the sampling ports 11 and the two plugging sleeves 21 are docked to block the sampling ports 11. By making the rotation directions of the adjusting baffles 211 on the upper and lower sides of the sampling ports 11 opposite, when the two plugging sleeves 21 rotate synchronously, they can approach or move away from the sampling ports 11 synchronously, facilitating sampling of the sample or blocking of the sampling ports 11.

[0046] In the present utility model, a docking soft pad 212 is provided at the docking position of the two plugging sleeves 21; by docking the two plugging sleeves 21 and squeezing the docking soft pad 212, the sampling port 11 can be tightly plugged, thereby avoiding the contamination of the sample during the sampling process.

[0047] In the present utility model, the length of the connecting pipe 284 is the same as the distance between the two sampling ports 11; it enables the staff to disassemble and assemble the connecting pipe 284, and then conduct stratified sampling of samples at different heights, making it more convenient for the staff to use and faster to locate.

[0048] In the present utility model, the distance between the upper piston 282 and the lower piston 281 is less than the sum of the lengths of the two plugging sleeves 21, ensuring that the upper piston 282 and the lower piston 281 can plug and separate the upper and lower ends of the docked plugging sleeve 21.

[0049] In the present utility model, the upper piston 282 and the lower piston 281 are movably inserted into the plugging sleeve 21 and are slidably connected to the plugging sleeve 21, and the outer ends of the two plugging sleeves 21 are open; this facilitates the insertion of the upper piston 282 and the lower piston 281 and their movement within the plugging sleeve 21.

[0050] When specifically using the present utility model, the staff takes out the sampling sleeve 1, and by rotating the adjustment handle 27, determines that the plugging sleeve 21 tightly plugs the sampling port 11, and then the staff can insert the sampling sleeve 1 into the soil at the sampling position.

[0051] After the sampling sleeve 1 is inserted, at this time, the staff, according to the sampling position, takes out the connecting pipe 284 and installs it on the sampling pipe 28. After the connecting pipe 284 is installed, the external connecting pipe 285 is installed on the connecting pipe 284, and then the staff can insert the sampling pipe 28 into the sampling sleeve 1 and make the lower piston 281 insert into the plugging sleeve 21.

[0052] The staff inserts the upper piston 282 and the lower piston 281 into the plugging sleeve 21, and then, by using the connecting pipe 284, makes the upper piston 282 and the lower piston 281 continuously insert downward. When the distance between the upper end of the external pipe 285 and the sampling sleeve 1 reaches the set value, at this time, the upper piston 282 and the lower piston 281 are inserted into the two plugging sleeves 21 corresponding to the sampling port 11 at the sampling position.

[0053] Then, the staff can rotate the adjustment handle 21, which drives the plugging sleeve 21 to rotate by rotating the adjustment handle 27, and makes the two plugging sleeves 21 move away from the sampling port 11 synchronously, so that the sampling port 11 is in an open state. Then, the moisture in the soil can be preliminarily filtered by the outer filter screen 113, then penetrate into the filter cotton 115, and the filter cotton 115 filters the sediment again. Then, the filtered sample penetrates between the two plugging sleeves 21 through the inner filter screen 114;

[0054] The upper and lower ends of the two plugging sleeves 21 are blocked by the upper piston 282 and the lower piston 281 respectively, so that the sample is stored in a closed space, and the moisture penetrating from other sampling ports 11 will not be mixed with the moisture at this sampling port 11, thus ensuring layered sampling. Then, the staff can wait for a certain time to make the sample fully penetrate into the plugging sleeve 21. Subsequently, the extraction device can be connected to the external connection pipe 285 to extract the sample.

[0055] When sampling again, the staff pulls out the sampling sleeve 1 from the soil, then flushes the device. After flushing it clean, it can be used again.

[0056] When the device is specifically used, the lower piston 281 can wipe the inner wall of the plugging sleeve 21 through the sliding connection with the plugging sleeve 21 to remove the moisture on the inner wall of the plugging sleeve 21 and ensure the accuracy of sampling.

[0057] When the device is specifically used, the plugging sleeve 21 is connected by the synchronous connecting rod 26 to make the two plugging sleeves 21 on the upper and lower sides of the sampling port 11 rotate synchronously. By using the sliding fit of the synchronous sliding rod 24 and the synchronous sleeve 23, the plugging sleeves 21 at adjacent sampling ports 11 can rotate synchronously, which is convenient for the staff to control the opening and closing of the sampling port 11.
