Description

Technical Field

[0001] The utility model relates to the field of groundwater fixed-depth sampling, and in particular to a groundwater fixed-depth sampling device. Background Art

[0002] The groundwater fixed-depth sampling device is a professional equipment used to collect groundwater samples at a specific depth. First, the sampling depth is determined by a positioning device, and then the sampling container is lowered to the specified depth through the sampling auxiliary components. During the descent, the blocking component prevents water from entering the sampling container. After reaching the predetermined depth, the blockage is released, and groundwater enters the sampling container under the action of static pressure. After sampling is completed, the sampling container is lifted to the ground through the sampling auxiliary components. It is widely used in hydrogeological research to help scientific researchers understand the chemical composition, water level changes, water flow rate and other information of groundwater, providing a basis for the rational development, utilization and protection of water resources.

[0003] In the specific sampling of groundwater at a fixed depth, the usual method is to place the container directly into the groundwater and then conduct sampling. After the sampling is completed, the container is taken out and tested. Although this method can sample groundwater, it cannot fix the depth of groundwater during the sampling process, and the sampled groundwater contains more impurities, which is inconvenient for the operator to conduct subsequent research. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides a groundwater fixed-depth sampling device that overcomes the above technical problems or at least partially solves the above problems.

[0016] The utility model provides a groundwater fixed depth sampling device, the beneficial effects of which include:

[0017] 1. Through the cooperation of the metering rope, container body, pull rope, metering rope, connecting rod, limit rod, water storage pipe, installation pipe, connecting pipe, motor and winding roller, the container body is placed from the trough body, and the pull rope and metering rope can move downward continuously. When the metering rope moves to the maximum length, the metering rope stops the limit rod and the water storage pipe through the connecting rod. At this time, since the water storage pipe is arranged in the container body, when the water storage pipe is stuck in the container body, the position of the installation pipe is at the same position as the position of the connecting pipe. At this time, ground water can enter the water storage cavity, thereby not only sampling of groundwater at a specified depth, but also because of the provision of the metering rope and connecting rod, the sampling stability can be improved when sampling groundwater.

[0018] 2. Through the mutual cooperation of the container body, the mounting cap, the limiting cap, the mounting pipe, the connecting pipe, the filter plate and the mounting rod, after the groundwater sampling is completed, the mounting cap will be removed, and after the removal is completed, the limiting cap will be removed. When removed, since the positions of the mounting pipe and the connecting pipe are higher than the filter plate, all impurities in the groundwater are filtered by the filter plate. After the filtration is completed, the impurities in the groundwater are dropped from the inside of the water storage chamber into the inside of the collection device. When it is necessary to process the impurities on the filter plate, the filter plate can be pulled out through the mounting rod, so that the impurities on the filter plate can be processed, thereby improving the practicality of the device.

After the adjustment is completed, the operator can The container body 2 is placed from the trough 22 and placed downward. After placement is completed, the pull rope 15 and the metering rope 17 can continue to move downward. When the metering rope 17 reaches its maximum length, the metering rope 17 can stop the limit rod 19 and the water storage pipe 25 from moving through the connecting rod 18. At this time, since the water storage pipe 25 is arranged in the container body 2, when the water storage pipe 25 is stuck inside the container body 2, the position of the installation pipe 23 is at the same position as the position of the connecting pipe 27. At this time, groundwater can enter the water storage chamber 28 through the installation pipe 23 and the connecting pipe 27. When the water storage chamber 28 is full, the operator can start the motor 13 to drive the winding roller 14 to rotate, and the winding roller 14 can drive the container body 2 and the water storage pipe 25 to move upward, so that not only the groundwater at a specified depth can be sampled, but also the metering rope 17 and the connecting rod 18 are set at the same time, when sampling groundwater, the stability of the sampling can be improved.

When the author needs to filter impurities in groundwater, after the groundwater sampling is completed, the operator can place a collection device under the container body 2, and then the operator can remove the installation cap 21. After the removal is completed, the limit cap 31 is removed. When removed, since the positions of the installation pipe 23 and the connecting pipe 27 are higher than the filter plate 3, all impurities in the groundwater are filtered by the filter plate 3. After the filtration is completed, they fall from the inside of the water storage chamber 28 into the inside of the collection device. The filtration is completed and studied later. When the operator needs to deal with the impurities on the filter plate 3, the operator can also pull out the filter plate 3 through the installation rod 29, so that the impurities on the filter plate 3 can be processed, which is convenient for the operator to use and improves the practicality of the device.

[0028] Reference Figure 1-Figure 4 In a preferred embodiment, a mounting hole is provided at the top of the container body 2, and a limiting rod 19 is inserted into the inside of the mounting hole. A connecting pipe 27 is provided on one side of the water storage pipe 25, and a mounting pipe 23 is provided on one side of the container body 2.

[0029] Specifically, the working process or working principle of the groundwater fixed depth sampling device is as follows: in the specific groundwater fixed depth sampling, the usual method is to put the container directly into the groundwater, and then take the sample. After the sampling is completed, the container is taken out, and after the taking out is completed, the test is carried out. Although this method can sample groundwater, it is impossible to fix the depth of groundwater during the sampling process, and the sampled groundwater has more impurities, which is not convenient for the operator to conduct subsequent research. Therefore, this technical solution can solve the above problems. When the operator needs to sample groundwater at a fixed depth, the operator can first install the device At the groundwater where sampling is required, the operator can then adjust the maximum length of the metering rope 17 according to the sampling depth. After the adjustment is completed, the operator can put the container body 2 into the trough 22 and place it downward. After the placement is completed, the pull rope 15 and the metering rope 17 can continue to move downward. When it moves to the maximum length of the metering rope 17, the metering rope 17 can stop the movement of the limit rod 19 and the water storage pipe 25 through the connecting rod 18. At this time, since the water storage pipe 25 is set in the container body 2, when the water storage pipe 25 is stuck in the interior of the container body 2, the position of the installation pipe 23 is at the same position as the position of the connecting pipe 27. At the same position, the groundwater can enter the water storage chamber 28 through the installation pipe 23 and the connecting pipe 27. When the water storage chamber 28 is full, the operator can start the motor 13 to drive the winding roller 14 to rotate, and the winding roller 14 can drive the container body 2 and the water storage pipe 25 to move upward, so that not only the groundwater at a specified depth can be sampled, but also the metering rope 17 and the connecting rod 18 are set at the same time. When sampling, the stability of the sampling can be improved, which is convenient for the operator to use. When the operator needs to filter impurities in the groundwater, when the groundwater sampling is completed, the operator can filter the impurities in the groundwater. A collecting device is placed under the main body 2, and then the operator can remove the mounting cap 21. After removal, the limiting cap 31 is removed. When removed, since the mounting pipe 23 and the connecting pipe 27 are positioned higher than the filter plate 3, all impurities in the groundwater are filtered by the filter plate 3. After the filtration is completed, they fall from the inside of the water storage chamber 28 into the inside of the collecting device. The filtration is completed and studied later. When the operator needs to process the impurities on the filter plate 3, the operator can also pull out the filter plate 3 through the mounting rod 29, so that the impurities on the filter plate 3 can be processed, which is convenient for the operator to use and improves the practicality of the device.
