[0017] A groundwater sampling and collection device for facilitating segmented collection, asFigure 1 As shown in the figure, it includes a bottom plate 1. Several moving wheels are movably installed on the bottom surface of the bottom plate 1. A moving plate 2 is slidably installed on the top surface of the bottom plate 1. A placement box 3 is rotatably installed on the top surface of the moving plate 2. A limiting component is installed on the top surface of the moving plate 2, and the limiting component can limit the placement box 3. A support 4 is fixedly installed on one side of the bottom plate 1, and a sampling mechanism is fixedly installed on one side of the support 4. Place several collection tubes with open tops into the placement box 3 in sequence, and then slide the placement box 3 to one side of the bottom plate 1. At the same time, place a counterweight on the other side of the bottom plate 1 to balance the weight of the bottom plate 1. After the placement box 3 moves to one side of the bottom plate 1, the top of the collection tube is located below the component in the sampling mechanism at this time. After the sampling mechanism takes out the water sample and flows it into the collection tube, then stop pumping water. At the same time, pull the placement box 3 back to the other side of the bottom plate 1, rotate the placement box 3 to make the new collection tube rotate to the water intake, and at the same time perform manual labeling operation on the collection tube with the placed water sample. During the manual labeling operation, the component in the sampling mechanism is separated from the water surface, and the remaining water in the sampling mechanism is discharged. After pushing the placement box 3 to one side of the bottom plate 1 again, the sampling mechanism re-enters the water surface and resumes sampling. During the whole operation process, it can avoid the influence of the previous residual water sample on the new water sample, and at the same time can perform labeling operation on the placed collection tube to avoid subsequent memory confusion and water sample confusion.
[0018] Specifically, the placement box 3 described in this embodiment includes an upper box body 301, several support rods 302, and a lower box body 303; Lower box body 303. The bottom end of the lower box body 303 is movably connected to the top surface of the moving plate 2 through a rotating shaft. The top end of the lower box body 303 is open. Several placement slots are opened on the inner wall of the bottom end of the lower box body 303, and fixing components are installed in the placement slots, and the fixing components can fix the collection tube; Support rods 302. The bottom ends of the support rods 302 are fixedly installed on the top surface of the lower box body 303, and several support rods 302 are evenly distributed around the center of the lower box body 303; Upper box body 301. The upper and lower ends of the upper box body 301 are transparent, and the top ends of the support rods 302 are fixedly connected to the bottom end of the upper box body 301.
[0019] Place the collection tube into the placement slot, and then fix the collection tube through the fixing component. Through the connection of the rotating shaft, the lower box body 303 can rotate, driving the upper box body 301 to rotate synchronously. Through the connection of the support rods 302, there is a gap between the upper box body 301 and the lower box body 303. Through the gap, the staff can perform the labeling operation, and the operation is convenient.
[0020] Furthermore, the fixing component described in this embodiment includes: Two arc-shaped clamping plates 5, and the two arc-shaped clamping plates 5 are located in the placement slot; Two sets of spring groups, each set of spring groups consists of at least two springs. The spring groups are located between the arc-shaped clamping plate 5 and the inner wall of the placement groove, and are fixedly connected to the arc-shaped clamping plate 5 and the inner wall of the placement groove respectively.
[0021] When placing the collection tube, push the two arc-shaped clamping plates 5 in opposite directions by hand, and then place the collection tube between the two arc-shaped clamping plates 5. Through the thrust of the springs, the two arc-shaped clamping plates 5 move relatively to clamp the collection tube, which can prevent the collection tube from shaking during the process of collecting water samples, prevent the water samples from not flowing into the collection tube, and also avoid the collection tube from shaking when rotating the placement box 3, and keep it stable during use.
[0022] Furthermore, the limiting component described in this embodiment includes: A fixed sleeve 6, the fixed sleeve 6 is fixedly installed on one outer wall of the lower box body 303; A T-shaped insertion rod 7, the vertical rod of the T-shaped insertion rod 7 passes through the fixed sleeve 6; Several slots 8, the slots 8 are opened on the top surface of the moving plate 2, and several slots 8 are evenly distributed around the center of the lower box body 303.
[0023] After the placement box 3 rotates, the vertical rod of the T-shaped insertion rod 7 passes through the fixed sleeve 6 and is inserted into the slot 8 to fix the position of the placement box 3 and prevent the placement box 3 from rotating again, and the operation is simple.
[0024] Even further, the sampling mechanism described in this embodiment includes: A long strip block 9, the long strip block 9 is placed vertically, a cavity is opened inside the long strip block 9, and the bottom end of the cavity communicates with the outside; A pump body, the pump body is fixedly installed on the top inner wall of the cavity, the water inlet of the pump body is connected to a first pipe, one end of the first pipe is fixedly installed with a counterweight block, and the water outlet of the pump body is connected to a second pipe; A coiler 10, the coiler 10 is installed in the middle of the cavity, and the first pipe is wound around the coiler 10; A diversion component, the diversion component is located on one side of the long strip block 9, and one end of the second pipe is located inside the diversion component.
[0025] The coiler 10 and the pump body are both connected to the wireless remote control module and the controller. A water flow sensor is installed on the diversion assembly. When the water flow sensor detects sufficient flow, it transmits a signal to the controller. The controller controls the pump body to stop working, and at the same time, the signal is also transmitted to the wireless remote control module to remind the user. When sampling water, the coiler 10 relaxes the first pipe, one end of the first pipe enters the water surface, the pump body works, the water sample is extracted through the first pipe, and enters the diversion assembly through the second pipe. The diversion assembly diverts the water sample into the collection pipe. After the diversion is completed, the placement box 3 drives the collection pipe away from the diversion assembly. At this time, the first pipe is rewound onto the coiler 10, that is, one end of the first pipe is away from the water surface. At this time, the pump body is controlled to continue working through the wireless remote control module. The pump body transports the water remaining in the first pipe into the second pipe, and then discharges the water through the diversion assembly to prevent the remaining water in the first pipe and the second pipe, avoiding affecting the next water sample extraction.
[0026] Furthermore, the diversion assembly described in this embodiment includes: A diversion pipe 11, both ends of the diversion pipe 11 are transparent, one end of the diversion pipe 11 is hingedly connected to the outer wall of one side of the long strip 9, one end of the diversion pipe 11 is communicated with the inside of the cavity, and one end of the second pipe is located inside the diversion pipe 11; An electric telescopic rod 12, the fixed end of the electric telescopic rod 12 is fixedly installed on the outer wall of one side of the long strip 9, and the moving end of the electric telescopic rod 12 is movably connected to the outer wall of the diversion pipe 11.
[0027] The electric telescopic rod 12 is connected to the wireless remote control module. During diversion, the electric telescopic rod 12 extends, pushing the diversion pipe 11 to turn outward around the hinge point. The other end of the diversion pipe 11 is located above the collection pipe. The water sample flowing out of the second pipe is diverted into the collection pipe through the action of the diversion pipe 11. After the collection is completed, the placement box 3 is pulled to the other side of the bottom plate 1, that is, the placement box 3 is not below the diversion pipe 11. The electric telescopic rod 12 is controlled to contract, and the diversion pipe 11 turns towards the long strip 9. At this time, the water remaining in the first pipe and the second pipe is diverted through the diversion pipe 11 and flows out. The water flows onto the bottom plate 1 during the process of discharging outward, and has no impact on components such as the bottom plate 1.
[0028] Furthermore, a support plate 13 is fixedly installed on the other side of the top surface of the bottom plate 1 in this embodiment. A reel is movably installed on the support plate 13. A crank is installed at the front end of the central axis of the reel. A soft wire is wound around the reel. One end of the soft wire is fixedly connected to one side of the moving plate 2. When retracting the placement box 3, turn the crank, and the soft wire is wound onto the reel, pulling the moving plate 2 to the other side of the bottom plate 1. The operation is simple. When pushing the placement box 3 to one side of the bottom plate 1, directly push the moving plate 2, and the reel automatically unwinds the wire.
