[0002] Mineral water contains a certain amount of mineral salts, trace elements, and carbon dioxide gas; under normal circumstances, its chemical composition, flow rate, and temperature are relatively stable within natural fluctuations. Mineral water resource exploration is a complex and systematic process, primarily aimed at identifying and determining the location, volume, quality, and extraction conditions of mineral water, providing a scientific basis for subsequent mineral water development. Once mineral water resources are discovered, water sampling and testing and analysis are necessary to determine the hydrogeological conditions.

[0003] When collecting mineral water samples, workers need to use a water sampling device to collect samples at different locations and depths to improve the accuracy of the test results. After collecting multiple water samples at different sampling depths in one location, workers need to go to the next location to collect multiple water samples at different depths. This requires multiple operations. After each sampling, the entire device needs to be removed from the water, then placed in the water and readjusted for the next sampling. This complex sampling process also makes it easy for water from other depths to seep into the sampling device during the process of placing the device in the water, affecting the accuracy of the sampling results. Summary of the Invention

[0004] The purpose of the present invention is to provide a water sample collection device for mineral water resource exploration, which can conveniently realize the process of collecting water samples at different depths, and can take out the collected water samples without moving the entire device out of the water body, thereby facilitating the next sampling process.

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0020] Example The following reference Figure 1-Figure 7As shown, further described in conjunction with a specific embodiment, this embodiment provides a water sample collection device for mineral water resource exploration, including a cylinder 1, a floating seat 3, a water intake mechanism 4 and two sets of pressing members 5. One end of the cylinder 1 is open and the other end is sealed. A plurality of water inlet pipes 2 are arranged circumferentially at the bottom of the cylinder 1. The water inlet pipes 2 include a horizontal section 21 located outside the cylinder 1 and an arc section 22 located inside the cylinder 1. When the sealed end of the cylinder 1 is placed in the water body and the open end of the cylinder 1 is located above the water surface, water will not flow out of the cylinder 1. The bottom wall and side walls of the cylinder 1 can only enter the arc section 22 from the horizontal section 21, and then enter the cylinder 1 from the arc section 22; the floating seat 3 is mounted on the outside of the cylinder 1 and can float on the water surface. The floating seat 3 is provided with a positioning member 31 for fixing the position of the cylinder 1; the floating seat 3 always floats above the water surface, and by changing the relative position of the cylinder 1 and the floating seat 3 and fixing the cylinder 1 by the positioning member 31, the depth of the cylinder 1 inserted into the water body can be changed, so that the water inlet pipe 2 can collect water samples at a specified depth. After collecting water samples at one location, the staff will pull the water sampling device as a whole in the water body to the next collection location, which can directly make the cylinder 1 collect water samples at the specified depth of the next collection location.

[0021] Reference Figure 1 As shown, the cylinder 1 is provided with graduated lines 15 along its height. The starting point of the graduated lines 15 is at the same level as the water inlet pipe 2. After the cylinder 1 and the floating seat 3 are placed together in the water body, the scale reading at the surface of the cylinder 1 is the sampling depth. Therefore, when sampling at a specific depth, it is only necessary to adjust the relative position of the cylinder 1 and the floating seat 3. After the cylinder 1 and the floating seat 3 are fixed in position, the scale reading at the intersection of the cylinder 1 and the water surface is consistent with the desired sampling depth, thus ensuring the accuracy of the sampling depth. To facilitate the staff to observe the scale reading at the intersection of the cylinder 1 and the water surface, a water level observation port 32 is provided on the floating seat 3 for observing the graduated lines 15.

[0022] Reference Figure 1 、 Figure 2 As shown, a guide strip 16 is axially disposed on the outer wall of the cylinder 1, and a guide notch 33 is provided in the floating seat 3 for the guide strip 16 to slide, thereby ensuring the stability of the cylinder 1 during relative displacement between the cylinder 1 and the floating seat 3. The positioning member 31 includes a positioning seat 311, to which a positioning screw 312 is threadedly connected. The end of the positioning screw 312 passes through the positioning seat 311 and is capable of abutting the cylinder 1. After the relative position of the cylinder 1 and the floating seat 3 is adjusted, the positioning screw 312 is tightened so that the end of the positioning screw 312 abuts against the outer wall of the cylinder 1, thereby securing the position of the cylinder 1.

[0023] Reference Figure 1 、 Figure 3As shown, two groups of pressing members 5 are located above the water inlet pipe 2 and can press the water inlet pipe 2, one group of pressing members 5 is installed in the cylinder 1, and the other group of pressing members 5 is installed outside the cylinder 1. Support blocks 11 for supporting the water inlet pipe 2 are provided on the inner wall and outer wall of the cylinder 1. When any group of pressing members 5 presses the water inlet pipe 2 to deform the water inlet pipe 2 and is in a closed state, water cannot enter the cylinder 1 through the water inlet pipe 2. The water intake mechanism 4 includes a mounting ring 41 and a driving assembly 42. A plurality of collecting cylinders 43 are distributed circumferentially on the mounting ring 41. The driving assembly 42 is used to drive the mounting ring 41 to slide along the length direction of the cylinder 1 to a specified depth in the cylinder 1, and drive the mounting ring 41 to rotate at the specified depth so that the plurality of collecting cylinders 43 move one by one to directly below the water inlet pipe 2. When water needs to be collected, the drive component 42 is started. The drive component 42 first drives the mounting ring 41 to move vertically to a specified depth in the cylinder 1. During the movement, the sampling tube on the mounting ring 41 is staggered with the position of the water inlet pipe 2, so that it can be smoothly lowered to the bottom of the water inlet pipe 2. Then the drive component 42 continues to drive the mounting ring 41 to rotate, so as to drive multiple collection tubes 43 to move at the same time. After the movement, each collection tube 43 is located directly below multiple water inlet pipes 2, so as to facilitate the collection of water samples entering the cylinder 1 from the water inlet pipe 2.

[0024] Reference Figure 4 、 Figure 5As shown, the driving assembly 42 includes a driving motor 421 and a screw 422. The open end of the cylinder 1 is fixedly installed with a support frame 423, and the sealed end of the cylinder 1 is welded with a mounting block 424. One end of the screw 422 is rotatably connected to the mounting block 424, and the other end is rotatably connected to the support frame 423. The driving motor 421 is fixedly installed on the support frame 423 and the output shaft of the driving motor 421 is fixedly connected to the screw 422; the middle part of the mounting ring 41 is threadedly sleeved on the screw 422, and a guide block 411 is provided on the mounting ring 41 and on the outside of each collecting cylinder 43. A plurality of guide grooves 12 are provided on the cylinder 1 in the vertical direction, and the bottom end of the guide groove 12 is connected to an arc groove 13. When the guide block 411 moves to the end of the guide groove 12, it can rotate into the arc groove 13. When the guide ring 411 reaches the end of the guide groove 12, it is no longer limited by the guide groove 12. Therefore, when the lead screw 422 continues to rotate, it can drive the mounting ring 41 to rotate and move the guide block 411 into the arc groove 13. The height of the arc groove 13 is lower than the height of the lowest end of the water inlet pipe 2. Therefore, when the mounting ring 41 drives the collection tube 43 to rotate, the collection tube 43 will not conflict with the water inlet pipe 2. When the guide ring moves to the end of the arc groove 13, the collection tube 43 is located directly below the water inlet pipe 2, so as to collect the water sample entering from the water inlet pipe 2.

[0025] Reference Figure 6 As shown, the mounting ring 41 is circumferentially provided with a plurality of placement rings 412 for placing the collection tubes 43. A support sheet 413 is provided on the mounting ring 41 and directly below the placement rings 412. The support sheet 413 is fixedly connected to the mounting ring 41 via a support rod 414. When the collection tube 43 is placed in the placement ring 412, the bottom end of the collection tube 43 is supported and stabilized by the support sheet 413. The support frame 423 includes a center plate 4231 and a plurality of connecting rods 4232. The multiple connecting rods 4232 are positioned one-to-one above the water inlet pipe 2. When the mounting ring 41 is moved upward to the open end of the cylinder body 1, the placement ring 412 is located in the gap between the two connecting rods 4232. Therefore, after the collection tube 43 is placed in the placement ring 412, it is also located in the gap between the two connecting rods 4232. This facilitates the removal of the collection tube 43 containing the water sample from the placement ring 412 and the placement of an empty collection tube 43 in the placement ring 412 for further sampling.

[0026] Reference Figure 4 、 Figure 6As shown, the clamping member 5 includes a clamping ring 51, and clamping electric cylinders 52 are provided on both sides of the top of the clamping ring 51, and the clamping electric cylinders 52 are fixed to the wall of the cylinder 1 through the mounting seat 53; the support block 11 is provided with a groove adapted to the shape of the water inlet pipe 2, and the two support blocks 11 can respectively support the horizontal section 21 and the arc section 22 of the water inlet pipe 2 to avoid the position of the water inlet pipe 2 from being offset, and the bottom of the clamping ring 51 is provided with an arc-shaped protrusion 511 for tightening the water inlet pipe 2 to close the water inlet pipe 2, so that when the water inlet pipe 2 is compressed, the cross-section of the water inlet pipe 2 is flattened from a circle, and finally the cross-section of the water inlet pipe 2 forms two arc-shaped line segments close to each other in the groove of the support block 11, thereby achieving the sealing effect on the water inlet pipe 2. When it is necessary to change the sampling position or sampling depth, the pressing piece 5 located inside the cylinder 1 is first pressed against the water inlet pipe 2, and then the pressing piece 5 located outside the cylinder 1 is pressed against the water inlet pipe 2 to reduce the amount of residual water in the water inlet pipe 2; after moving to the designated sampling position, the pressing piece 5 located inside the cylinder 1 is kept in a pressed state, and the pressing piece 5 located outside the cylinder 1 repeats the process of loosening and pressing, that is, the water at the sampling position after movement can enter the water inlet pipe 2 and replace the water sample remaining in the water inlet pipe 2, thereby discharging the water at the original sampling position to improve the accuracy of sampling; when sampling, the water sampling device as a whole is rotated at a specified angle in the water body, so that the positions of multiple water inlet pipes 2 change at the same time, so that the water sample during the water intake process will not be affected by the residual water sample.

[0027] Reference Figure 7 As shown, the barrel 1 is provided with a plurality of through slots, the area of which is larger than the cross-sectional area of the water inlet pipe 2. An elastic diaphragm 14 is disposed within the through slots, and the water inlet pipe 2 is passed through the elastic diaphragm 14, with the outer wall of the water inlet pipe 2 fixedly connected to the elastic diaphragm 14. When the compression ring 51 presses the water inlet pipe 2, the shape of the water inlet pipe 2 changes to ensure that the compression position is in a closed state. By providing the through slots and disposing the elastic diaphragm 14 in the barrel 1, the elastic diaphragm 14 can deform to adapt to the changes in the shape of the water inlet pipe 2. Therefore, the elastic diaphragm 14 can adapt to the changes in the shape of the water inlet pipe 2 while ensuring the sealing of the connection between the water inlet pipe 2 and the through slots, thereby preventing water samples from entering the barrel 1 through the gap.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
