Description

Technical Field

[0001] This utility model relates to the technical field of hydrogeological sampling devices, and in particular to a hydrogeological sampling device. Background Technology

[0002] In fields such as hydrogeological research, water resource monitoring, and environmental assessment, water sampling is a crucial step in obtaining information on groundwater and surface water. Hydrogeological research aims to gain a deeper understanding of the formation, distribution, movement patterns, and water quality characteristics of groundwater. In many research projects, accurate analysis of water samples from different depths and locations is a vital step.

[0003] Staff often find that most of the current hydrogeological sampling devices are single-sampling structures, which can only collect water samples from one specific location at a time. If multiple sampling points need to be carried out at different depths and in different areas of the same water body, the sampling equipment needs to be operated repeatedly, resulting in a lot of time and manpower being wasted. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hydrogeological sampling device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hydrogeological sampling device, comprising a U-shaped base, a winding shaft rotatably connected to the U-shaped base via bearings, a first motor fixedly connected to the U-shaped base, the winding shaft being driven to rotate by the first motor, a connecting line fixedly connected to the winding shaft, a sampling cylinder fixedly connected to one end of the connecting line, a high-efficiency structure provided on the sampling cylinder, the high-efficiency structure mainly consisting of three partitions, all three partitions being fixedly connected in the sampling cylinder, a rotating plate rotatably connected to the sampling cylinder, a water inlet provided on the rotating plate, an installation groove provided on the rotating plate, a cover plate rotatably connected to the installation groove via a hinge, a second motor fixedly connected to the rotating plate, and the cover plate being driven to rotate by the second motor.

[0006] The aforementioned components achieve the following effect: The U-shaped base is placed at the sampling port of a well or spring, and the sampling cylinder is lowered into the water. The output of the first motor (model 17HS4401) is connected to the winding shaft via a reducer and coupling. First, the power is switched on to power the control system of the first motor. Then, starting the first motor drives the winding shaft to rotate, which in turn drives the connecting wire to unwind. Three partitions divide the sampling cylinder into three storage spaces. When the sampling cylinder reaches the designated height, the output of the second motor (connected to the cover plate via a reducer and coupling)... Next, the second motor, model 28BYJ-48, is powered on to activate the control system of the second motor. Then, starting the second motor will drive the cover to rotate and open, allowing water to enter a storage space. The sampling tube then moves to the next sampling position. Rotating the rotating plate will position the inlet in the next storage space. The above operation is repeated to collect samples. There is no need to retrieve and unwind the connecting cable, thus avoiding the need to repeatedly operate the sampling equipment to sample multiple points at different depths and in different areas of the same water body, which would otherwise consume a lot of time and manpower.

[0007] Preferably, a sealing ring is fixedly connected to the cover plate, and the sealing ring is made of rubber.

[0008] The effect achieved by the above components is that the sealing ring can improve the sealing between the cover plate and the mounting groove, preventing leakage.

[0009] Preferably, a disc gear is fixedly connected to the rotating plate, and a spur gear is meshed with the disc gear. The spur gear is rotatably connected to the sampling cylinder through a bearing.

[0010] The effect achieved by the above components is that rotating the flat gear can drive the disc gear to rotate, thereby causing the rotating plate to rotate.

[0011] Preferably, a third motor is fixedly connected to the sampling cylinder, and the spur gear is driven to rotate by the third motor.

[0012] The effect achieved by the above components is as follows: the output end of the third motor is connected to the flat gear through a reducer and a coupling. The model of the third motor is 17HS4401. First, the power is turned on to power the control system of the third motor. Then, the third motor is started to drive the flat gear to rotate. The gear and motor components located in the water are all equipped with sealed waterproof covers.

[0013] Preferably, the water inlet is provided with a filter structure, which mainly consists of a filter plate, and the filter plate is disposed in the water inlet.

[0014] The effect achieved by the above components is that the filter plate can filter impurities in the water to prevent them from affecting the subsequent water sample test data.

[0015] Preferably, the filter plate has three sliding grooves, a slider is slidably connected in the sliding groove, a locking rod is fixedly connected to the slider, the locking rod is slidably inserted in the sliding groove, and three locking slots are formed on the inner wall of the water inlet.

[0016] The above components achieve the following effects: sliding the three sliders allows the locking rod to be inserted into the corresponding locking slot, facilitating the installation of the filter plate; conversely, sliding them allows the filter plate to be disassembled and cleaned.

[0017] Preferably, a spring is fixedly connected to the slider, and one end of the spring is fixedly connected to the inner wall of the groove.

[0018] The effect achieved by the above components is that when the locking rod is inserted into the locking slot, the spring is in a contracted state, so the spring's rebound force acts on the slider, making the limiting more stable.

[0019] Preferably, a knob is rotatably connected to the filter plate, and three pull ropes are fixedly connected to the knob, with one end of each pull rope fixedly connected to the slider.

[0020] The effect achieved by the above components is that turning the knob will cause the three pull ropes to pull the three sliders simultaneously, making the operation more convenient.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting an efficient structure, the U-shaped seat is placed at the sampling port of a well or spring, and the sampling tube is placed into the water. The output end of the first motor is connected to the winding shaft through a reducer and coupling. The first motor is model 17HS4401. First, the power is turned on to power the control system of the first motor. Then, starting the first motor drives the winding shaft to rotate, which in turn drives the connecting wire to unwind. Three partitions divide the sampling tube into three storage spaces. When the sampling tube reaches the designated height, the output of the second motor... The outlet is connected to the cover plate via a reducer and coupling. The second motor is model 28BYJ-48. First, the power is turned on to power the control system of the second motor. Then, the second motor is started to drive the cover plate to rotate and open, allowing water to enter a storage space. Then, the sampling tube moves to the next sampling position. Rotating the rotating plate makes the water inlet located in the next storage space. The above operation is repeated to collect samples. There is no need to retrieve and unwind the connecting line, thus avoiding the situation where multiple sampling points are required for different depths and areas of the same water body, which would consume a lot of time and manpower.

[0027] Example 1, as Figure 1 As shown, a hydrogeological sampling device includes a U-shaped base 1, a winding shaft 2 rotatably connected to the U-shaped base 1 via a bearing, a first motor 3 fixedly connected to the U-shaped base 1, the winding shaft 2 being driven to rotate by the first motor 3, a connecting line 4 fixedly connected to the winding shaft 2, and a sampling cylinder 5 fixedly connected to one end of the connecting line 4.

[0028] Reference Figures 1 to 3The sampling cylinder 5 is equipped with a high-efficiency structure 6, which mainly consists of three partitions 61, all of which are fixedly connected to the sampling cylinder 5. A rotating plate 62 is rotatably connected to the sampling cylinder 5. The rotating plate 62 has a water inlet 63 and an installation groove 64. A cover plate 65 is rotatably connected to the installation groove 64 via a hinge. A second motor 66 is fixedly connected to the rotating plate 62. The cover plate 65 is driven to rotate by the second motor 66. The U-shaped seat 1 is placed at the sampling port of a well or spring, and the sampling cylinder 5 is dropped into the water. The output end of the first motor 3 is connected to the winding shaft 2 via a reducer and a coupling. The first motor 3, model 17HS4401, is powered on by first connecting the power supply to the control system of the first motor 3. Starting the first motor 3 drives the winding shaft 2 to rotate, which in turn drives the connecting wire 4 to unwind. Three partitions 61 divide the sampling cylinder 5 into three storage spaces. When the sampling cylinder 5 reaches the designated height, the output end of the second motor 66, model 28BYJ-48, is connected to the cover plate 65 via a reducer and coupling. First connecting the power supply to the control system of the second motor 66, starting the second motor 66 drives the cover plate 65 to rotate and open, allowing water to enter one of the storage spaces. Then, the sampling cylinder 5 moves to the next sampling position, and the rotating plate 62 is rotated so that the inlet 63 is located in the next storage space. The above operation is repeated to collect samples. There is no need to retrieve the unwinding connection line 4, thus avoiding the need to repeatedly operate the sampling equipment for sampling at different depths and in different areas of the same water body, which would consume a lot of time and manpower. A sealing ring 67 is fixedly connected to the cover plate 65. The sealing ring 67 is made of rubber and can improve the sealing between the cover plate 65 and the mounting groove 64 to prevent leakage. A disc gear 68 is fixedly connected to the rotating plate 62, and a flat gear 6 is meshed on the disc gear 68. 9. The spur gear 69 is rotatably connected to the sampling cylinder 5 via a bearing. Rotating the spur gear 69 can drive the disc gear 68 to rotate, causing the rotating plate 62 to rotate. A third motor 610 is fixedly connected to the sampling cylinder 5. The spur gear 69 is driven to rotate by the third motor 610. The output end of the third motor 610 is connected to the spur gear 69 via a reducer and a coupling. The model of the third motor 610 is 17HS4401. First, the power is turned on to power the control system of the third motor 610. Then, starting the third motor 610 can drive the spur gear 69 to rotate. The gears and motors located in the water are all covered with sealed waterproof covers.

[0029] Reference Figure 3 and Figure 4A filter structure 7 is installed in the water inlet 63. The filter structure 7 mainly consists of a filter plate 71. The filter plate 71 is installed in the water inlet 63 and can filter impurities in the water to prevent them from affecting the subsequent water sample test data. Three sliding grooves 72 are opened on the filter plate 71, and sliders 73 are slidably connected in the sliding grooves 72. A locking rod 74 is fixedly connected to the slider 73 and is slidably inserted into the sliding groove 72. Three locking slots 75 are opened on the inner wall of the water inlet 63. Sliding the three sliders 73 can insert the locking rod 74 into the corresponding locking slot 75, which facilitates the adjustment of the filter plate 71. Install the filter plate 71, or disassemble and clean it. A spring 76 is fixedly connected to the slider 73. One end of the spring 76 is fixedly connected to the inner wall of the slide groove 72. When the locking rod 74 is inserted into the locking groove 75, the spring 76 is in a contracted state. Therefore, the rebound force of the spring 76 acts on the slider 73, making the limit more stable. A knob 77 is rotatably connected to the filter plate 71. Three pull ropes 78 are fixedly connected to the knob 77. One end of the pull ropes 78 is fixedly connected to the slider 73. Rotating the knob 77 will drive the three pull ropes 78 to pull the three sliders 73 simultaneously, making the operation more convenient.

[0030] Working principle: The U-shaped seat 1 is placed at the sampling port of a well or spring, and the sampling cylinder 5 is placed into the water. The output end of the first motor 3 is connected to the winding shaft 2 through a reducer and coupling. The model of the first motor 3 is 17HS4401. First, the power is turned on to power the control system of the first motor 3. Then, the first motor 3 is started, which drives the winding shaft 2 to rotate, thereby driving the connecting wire 4 to unwind. Three partitions 61 divide the sampling cylinder 5 into three storage spaces. When the sampling cylinder 5 reaches the designated height, the output end of the second motor 66 is connected to the winding shaft 2 through a reducer and coupling. Connected to the cover plate 65, the second motor 66, model 28BYJ-48, first powers on the control system of the second motor 66, then starts the second motor 66 to rotate and open the cover plate 65, allowing water to enter a storage space. The sampling cylinder 5 then moves to the next sampling position. Rotating the rotating plate 62 positions the inlet 63 in the next storage space. This process is repeated for sampling, eliminating the need to retrieve and rewind the connecting cable 4. This avoids the need for repeated operation of the sampling equipment when sampling at different depths and areas of the same water body, which can lead to... This process, which consumes a significant amount of time and manpower, improves the sealing performance between the cover plate 65 and the mounting groove 64, preventing leakage. Rotating the spur gear 69 drives the disc gear 68 to rotate, causing the rotating plate 62 to rotate. The output end of the third motor 610 is connected to the spur gear 69 via a reducer and coupling. The model of the third motor 610 is 17HS4401. First, the power is connected to power the control system of the third motor 610. Then, starting the third motor 610 drives the spur gear 69 to rotate. Gears and motors located in the water are equipped with... With a sealed waterproof cover, the filter plate 71 can filter impurities in the water to prevent them from affecting the subsequent water sample test data. Sliding the three sliders 73 can insert the locking rod 74 into the corresponding locking slot 75, making it easy to install the filter plate 71. Conversely, the filter plate 71 can be disassembled and cleaned. When the locking rod 74 is inserted into the locking slot 75, the spring 76 is in a contracted state. Therefore, the rebound force of the spring 76 acts on the slider 73, making the limit more stable. Turning the knob 77 will drive the three pull ropes 78 to pull the three sliders 73 simultaneously, making the operation more convenient.
