Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping sampling, and in particular to an automatic sampling device and method based on hydrological surveying and mapping. Background Art

[0002] In the field of hydrological mapping, accurate and efficient sampling of groundwater and surface water is a key step in assessing water quality, water quantity and hydrological cycle processes.

[0003] For example, the patent application with the prior art publication number CN114383897A discloses a sampling device for geological surveying, including a housing, and also including a water intake mechanism connected by a winding mechanism, which is used to sample water flow, wherein the water intake mechanism includes a water intake housing, and a water inlet hole is provided on the outer wall of the water intake housing. When the present invention is used, the water intake housing is slowly placed in water through the winding mechanism, and when the second base falls to the bottom of the water, the pushing component pushes the protruding component along with the movement of the movable rod, thereby pushing the mud collection housing to a horizontal setting, and at this time, the inside of the mud collection housing is pumped with negative pressure through the mud pumping component to achieve sludge sampling, and water flows into the water intake housing through the water inlet hole to achieve sampling of water flow, which is convenient and efficient to use, and the mud collection housing can be automatically flipped to a horizontal level for sampling when the device falls to the bottom of the water, and when the water collection housing falls, the vertically arranged mud collection housing reduces the resistance of falling.

[0004] In the prior art, by designing a unique mud collection shell, remarkable results have been achieved in reducing the resistance of the water collection shell when it falls vertically underwater. However, this design has exposed a key limitation in actual application: it mainly focuses on optimizing the resistance in the vertical direction, but fails to fully cope with the complex underwater flow field environment, especially the challenges posed by underwater undercurrents. Specifically, when the sampling device encounters a strong underwater undercurrent, its stability will be seriously threatened. Undercurrents often have unpredictable directions and intensities, which not only have a direct impact on the device, but may also cause the device to swing violently underwater. This swing will not only increase the tension of the connecting rope, causing it to bear additional loads, but may also cause the water collection shell to deviate from the predetermined descent trajectory and fail to reach the predetermined sampling depth or position normally. To this end, the present application proposes an automatic sampling device and method based on hydrological mapping. Summary of the invention

[0015] The present invention also provides an automatic sampling method based on hydrological surveying and mapping, comprising the following steps: S1. When in use, first move the bracket down into the water; S2. When the bracket is subjected to turbulent swing underwater, it will have a certain inclination, which is derived from the direction of the convection undercurrent. When it inclines, it will drive the stabilizing component to operate so that the second streamline plate and the first streamline plate are closed to each other, thereby forming a streamlined structure to resist the undercurrent and reduce the shaking of the bracket; S3. When the first streamline plate and the second streamline plate are closed at the same time, the auxiliary component is operated at the same time to close the flat plate, and cooperates with the closing of the first streamline plate and the second streamline plate to better resist turbulence; S4. When it is necessary to sample groundwater, the driving assembly is operated to cause the offset plate to move in a circle along the center of the sampling tube and to be offset from the filter hole so as to be unable to block the filter hole. At this time, water will flow into the sampling tube, and at the same time, the closing assembly is operated to cause multiple partitions to form multiple compartments to store groundwater samples.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the coordination of the winding hoist and the winding wire, as well as the support of the floating plate, the device can easily adapt to sampling in waters of different depths. The built-in encoder of the driving motor can accurately record the number of rotations, so as to know the lowering length of the bracket. The bracket and the first and second streamlined plates on it adopt a streamlined design, which can effectively reduce the water flow resistance. The stabilizing component can intelligently adjust the rotation angle of the first and second streamlined plates through the coordination of the transmission motor, the driving gear, the first steering idler, the second steering idler, the transmission gear, the driving wheel, the driven wheel and the toothed belt to cope with the complex undercurrent underwater. This intelligent adjustment mechanism ensures the stability of the device in a complex water flow environment. When the bracket is tilted by the undercurrent disturbance, the ball in the inclined plate will roll and resist the button switch, thereby starting the transmission motor for self-protection. This design not only improves the safety of the device, but also reduces the sampling error caused by water flow disturbance. The auxiliary components consisting of the plate and the crank, the resistance block, the connecting rod, the arc sheet and the torsion spring on it can further enhance the stability of the device.

[0017] 2. The filter holes set on the outside of the sampling tube can effectively filter impurities in the groundwater and ensure the purity of the sampling. At the same time, the servo motor drives the connecting handle and the offset plate to make circular motion, which can intermittently open and close the filter holes. The partitions and closing components set inside the sampling tube can intelligently separate the storage space, so that groundwater samples of different depths can be stored separately. When the servo motor is running, the grooves on the partition can be flexibly closed or opened through the cooperation of the transmission wedge and the connecting rod, so as to form one or more compartments. Through the continuous transmission of the servo motor and the intelligent control of the closing component, it can be ensured that groundwater samples of different depths will not be confused with each other during the sampling process. When the sampling tube descends to different depths, the servo motor will first close the lowest partition to form a compartment to store the groundwater samples of the current depth. Subsequently, as the sampling tube continues to descend and the servo motor runs again, other partitions can be closed in turn to form multiple compartments to store groundwater samples of different depths, and the operation of the two cooperates with each other.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3 The present invention provides a technical solution: an automatic sampling device based on hydrological surveying and mapping, comprising a winding hoist 100, a winding wire 101 wound on the surface thereof, and a fixed frame 102 for rotationally connecting the winding hoist 100, a driving motor 104 is fixedly connected to one side of the fixed frame 102, and an output end of the driving motor 104 is fixedly connected to the winding hoist 100, and a floating plate 103 is fixedly connected to the bottom of the fixed frame 102, and the floating plate 103 is used to support the winding hoist 100 and park the winding hoist 100 on the lake surface, so as to adapt to water depth sampling at different positions; It also includes a bracket 200, the top of which is connected to one end of the winding line 101. The bracket 200 rotates in a divergent state along its center and is connected to two first streamline plates 201 and two second streamline plates 202, and the two first streamline plates 201 and the two second streamline plates 202 are arranged in a staggered manner. The interior of the bracket 200 is provided with a stabilizing component that drives the first streamline plates 201 and the second streamline plates 202 to rotate in opposite directions and cooperate with the water flow. The bottom of the bracket 200 is fixedly connected to a gravity ball 105, wherein the encoder in the driving motor 104 can follow the number of rotations to know the lowering length of the bracket 200, and the wires connected inside the winding line 101 can control the start and stop of the electrical components in the bracket 200, and the gravity ball 105 can stretch the winding line 101 so that the bracket 200 can move downward stably, and its stabilizing component can control the rotation angles of the first streamline plates 201 and the second streamline plates 202 to adapt to the underwater undercurrent, thereby ensuring the stable downward movement of the bracket 200; For further information, see Figure 5 , Figure 6 as well as Figure 7The stabilizing component includes a transmission motor 203 fixedly connected to the inside of the bracket 200, and the output end of the transmission motor 203 is fixedly connected to a driving gear 204, the inside of the bracket 200 is rotatably connected to two transmission gears 207 fixedly connected to the first streamline plate 201, and the inside of the bracket 200 is rotatably connected to two first steering idler wheels 205 meshed with the driving gear 204, the inside of the bracket 200 is rotatably connected to two second steering idler wheels 206 meshed with the transmission gear 207, and the two second steering idler wheels 206 are respectively meshed with the two first steering idler wheels 205, the top of the driving gear 204 is fixedly connected to a driving wheel 209, and the inside of the bracket 200 is rotatably connected to two driven wheels 202 fixedly connected to the second streamline plate 202 08, and the two driven wheels 208 are connected to the driving wheel 209 by means of a toothed belt 210. The driving gear 204 can be driven to rotate by operating the transmission motor 203. In cooperation with the first steering idler wheel 205 and the second steering idler wheel 206, the two transmission gears 207 can rotate in opposite directions to the driving gear 204 respectively. At the same time, in cooperation with the driving wheel 209 and the driven wheel 208, the driving gear 204 and the driven wheel 208 can rotate in the same direction, which makes the first streamline plate 201 and the second streamline plate 202 rotate in opposite directions, so that they can be closed to form a flow pattern to resist the undercurrent. Under the action of the toothed belt 210, its teeth can effectively increase the friction force without causing the driven wheel 208 and the driving wheel 209 to slip.

[0022] In order to deal with the complex undercurrents, please refer to Figure 6 , Figure 7 as well as Figure 8 , a plurality of inclined plates 211 are fixedly connected inside the bracket 200, and rolling grooves 213 are opened in the plurality of inclined plates 211, and balls 212 sliding by gravity are slidably connected inside the rolling grooves 213, and button switches 214 are fixedly connected inside the plurality of rolling grooves 213, and the button switches 214 are connected to the transmission motor 203 through conductive wires 215 to transmit electrical signals, and the plurality of inclined plates 211 are evenly located between the first streamline plate 201 and the second streamline plate 202, and are in a cross-divergent state, which can flexibly cope with underwater auxiliary undercurrents, and when the bracket 200 is tilted by the undercurrent disturbance, the inclined plate 211 facing the undercurrent will be located at a low position, at which time the balls 212 will slide in the inclined plate 211 under gravity and contact the button switch 214 to start the transmission motor 203 to rotate, so that the first streamline plate 201 and the second streamline plate 202 facing the turbulent flow are closed, thereby reducing the contact surface of the undercurrent with the bracket 200.

[0023] Specifically, when the bracket 200 is swung by a turbulent undercurrent underwater, a certain inclination will be generated. The inclination is derived from the direction of the convection undercurrent. When tilted, the ball 212 facing the undercurrent direction will be driven to roll in the rolling groove 213, and finally the button switch 214 will be resisted to release the electric signal to start the transmission motor 203. The transmission motor 203 drives the driving gear 204 to rotate, thereby driving the first steering idler wheels 205 on both sides thereof to rotate, while driving the second steering idler wheel 206 to rotate, thereby driving the transmission gear 207 to rotate. At this time, the two transmission gears 207 rotate in the same direction, thereby moving in the direction close to the second streamline plate 202 respectively. While the driving gear 204 rotates, it will drive the driving wheel 209 to rotate, thereby transmitting the two driven wheels 208 to rotate synchronously through the toothed belt 210. At this time, the rotation direction of the driven wheel 208 is the same as that of the driving gear 204 and opposite to that of the two transmission gears 207, so that the second streamline plate 202 and the first streamline plate 201 are closed to each other, thereby forming a streamlined structure to resist the undercurrent and reduce the shaking of the bracket 200.

[0024] At the same time, when facing complex undercurrents, the streamlined state can be changed by changing the rotation direction of the output shaft of the transmission motor 203 to cope with the changeable undercurrents. With the cooperation of the rolling groove 213 and the button switch 214, the two adjacent button switches 214 respectively control the forward and reverse rotation of the transmission motor 203, and the closing position of the first streamline plate 201 and the second streamline plate 202 can be changed according to the inclination angle of the bracket 200.

[0025] For further information, see Figure 2 See also Figure 1 , Figure 2 as well as Figure 3 , Figure 3 as well as Figure 4 , also includes a flat plate 400, which is evenly arranged on the outer surface of the bracket 200, and an auxiliary component that cooperates with the stabilizing component is arranged on the top of the flat plate 400. The auxiliary component includes a crank 402 fixedly connected to the tops of the two first streamline plates 201 and the two second streamline plates 202 respectively, and the top of the bracket 200 is evenly slidably connected with a plurality of interference blocks 401 that can interfere with the crank 402, and the top of the bracket 200 is rotatably connected with a plurality of connecting rods 403 fixedly connected to the flat plate 400, and the outer surfaces of the plurality of connecting rods 403 are all fixedly connected with arc pieces 405 that interfere with the interference blocks 401, and the outer surfaces of the plurality of connecting rods 403 are all sleeved with torsion springs 404 for their own reset. By setting the flat plate 400, it can be closed with the closing of the first streamline plate 201 and the second streamline plate 202, thereby assisting the two sides of the closing of the first streamline plate 201 and the second streamline plate 202, thereby assisting the flow resistance of the bracket 200.

[0026] Specifically, when the first streamline plate 201 and the second streamline plate 202 are closed, the crank 402 connected thereto will rotate and abut against the abutment blocks 401 located on both sides of the bracket 200, so that the abutment blocks 401 move to abut against the misalignment of the arc-shaped pieces 405 and drive the connecting rod 403 to rotate, so that the flat plate 400 is closed, cooperating with the closing of the first streamline plate 201 and the second streamline plate 202 to better abut against turbulence.

[0027] In summary, through the cooperation of the winding hoist 100 and the winding wire 101, and the support of the floating plate 103, the device can easily adapt to sampling in waters of different depths. The driving motor 104 has a built-in encoder, which can accurately record the number of rotations, thereby knowing the lowering length of the bracket 200. The bracket 200 and the first streamline plate 201 and the second streamline plate 202 thereon adopt a streamlined design, which can effectively reduce water flow resistance. The stabilizing component can intelligently adjust the rotation angle of the first streamline plate 201 and the second streamline plate 202 through the cooperation of the transmission motor 203, the driving gear 204, the first steering idler wheel 205, the second steering idler wheel 206, the transmission gear 207, the driving wheel 209, the driven wheel 208 and the toothed belt 210 to cope with complex underwater undercurrents. This intelligent adjustment mechanism ensures the stability of the device in a complex water flow environment. When the bracket 200 is tilted by undercurrent disturbance, the ball 212 in the inclined plate 211 will roll against the button switch 214, thereby starting the transmission motor 203 for self-protection. This design not only improves the safety of the device, but also reduces the sampling error caused by water flow disturbance. The auxiliary components composed of the flat plate 400 and the crank 402, the contact block 401, the connecting rod 403, the arc piece 405 and the torsion spring 404 thereon can further enhance the stability of the device.

[0028] Example 2: Please refer to Fig. 9 , Fig.10 as well as Fig.11 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: the automatic sampling device based on hydrological surveying and mapping also includes a sampling barrel 300, whose internal structure is hollow and fixedly connected to the inside of the bracket 200, the sampling barrel 300 is used to take groundwater, and its outer surface is evenly provided with a plurality of filter holes 301 for water to pass through, the filter holes 301 can filter impurities in the groundwater, the interior of the sampling barrel 300 is provided with a plurality of offset plates 304 adapted to the filter holes 301, and the interior of the sampling barrel 300 is provided with a driving component for driving the plurality of offset plates 304 to move and be offset with the filter holes 301, and by setting the driving component, the offset plates 304 can be easily offset to open the filter holes 301, so that the water outside the sampling barrel 300 is poured into the interior of the sampling barrel 300 for sampling; See also Fig.12 , Fig.13 as well as Fig.14The driving assembly includes a servo motor 302 fixedly connected to the inside of the sampling barrel 300, and the output end of the servo motor 302 is fixedly connected to a plurality of connecting handles 303 fixedly connected to the offset plates 304. The inside of the sampling barrel 300 is fixedly connected to a guide plate 307 for guiding water flow. The outer surface of the sampling barrel 300 is slidably connected to a plurality of cleaning blocks 305 that interfere with the filter holes 301, and the outer surfaces of the plurality of cleaning blocks 305 are evenly fixedly connected to a plurality of blades 306. When the servo motor 302 is running, it will drive the plurality of offset plates 304 to perform a circular motion, thereby intermittently opening the filter holes 301 to allow groundwater to enter the sampling barrel 300.

[0029] See also Fig.13 , Fig.14 as well as Fig.15 The sampling tube 300 is provided with a plurality of partitions 308 for separating the spaces, and a sealing assembly is provided inside the partitions 308, the sealing assembly includes a sealing baffle 312 slidably connected to the interior of the plurality of partitions 308, and the interior of the plurality of partitions 308 is evenly provided with a plurality of notches 310, and the plurality of sealing baffles 312 are respectively adapted to the plurality of notches 310, and the interior of the plurality of partitions 308 is staggeredly fixedly connected with a plurality of limiting plates 313 for preventing the sealing baffles 312 from moving, and the plurality of notches 310 are fixedly connected to the interior of the plurality of partitions 308. A rotating shaft 311 is connected for common rotation therebetween, a plurality of spring leaves 316 are fixedly connected inside the rotating shaft 311, and the elastic ends of the plurality of spring leaves 316 are fixedly connected to a transmission wedge 315, and one end of a plurality of sealing baffles 312 is fixedly connected to a connecting rod 314 that can contact the transmission wedge 315, wherein when the transmission wedge 315 contacts the connecting rod 314, the sealing baffle 312 will be driven to rotate and close the groove 310, and when the connecting rod 314 cannot be pushed, the inclined surface of the transmission wedge 315 will pass over the connecting rod 314.

[0030] It is worth mentioning that the multiple offset plates 304 cooperate with the multiple filter holes 301, so that the servo motor 302 is driven slightly to open the filter holes 301, and subsequently it will continue to overlap with the filter holes 301 to block the filter holes 301, thereby preventing groundwater from entering the sampling tube 300. When groundwater enters the sampling tube 300, it will pass through the notches 310 in the multiple partitions 308 and enter the bottom of the sampling tube 300. When the servo motor 302 is running, it will first close the bottom partition 308, thereby forming a The servo motor 302 is then stopped until the bracket 200 is at another depth and is then run again to allow groundwater to enter the top of the lowest driven wheel 208. At the same time, the continued operation of the servo motor 302 will close the middle partition 308 to form a compartment again. In this way, multiple compartments can be formed to store groundwater samples at different depths. At the same time, the continuous transmission of the servo motor 302 will prevent the transmission wedge 315 from pushing the connecting rod 314 to move, thereby compressing the reed 316 and passing over the connecting rod 314, so that the servo motor 302 can run flexibly without getting stuck.

[0031] Specifically, when it is necessary to sample groundwater, the servo motor 302 is started to drive multiple connecting handles 303 to rotate, so that the offset plate 304 moves in a circle along the center of the sampling tube 300, so that the offset plate 304 is misaligned with the filter hole 301 and cannot block the filter hole 301. At this time, water will flow into the sampling tube 300. At the same time, when the servo motor 302 is running, it will drive the rotating shaft 311 to rotate on the outer surface of the partition 308, so that the transmission wedge 315 in the rotating shaft 311 continuously pushes the connecting rod 314 to move, thereby driving the sealing baffle 312 to approach the groove 310, thereby blocking the partition 308. At the same time, the partition 308 located at the bottom will be blocked first to form a compartment to block groundwater at different depths. Subsequently, the rotating shaft 311 is continuously driven to rotate to intermittently block the partition 308 to form multiple compartments at a time.

[0032] In summary, the filter hole 301 provided on the outside of the sampling barrel 300 can effectively filter impurities in the groundwater and ensure the purity of the sampling. At the same time, the servo motor 302 drives the connecting handle 303 and the dislocation plate 304 to make circular motion, and the filter hole 301 can be intermittently opened and closed. The partition 308 and the closing assembly provided inside the sampling barrel 300 can intelligently separate the storage space, so that groundwater samples of different depths can be stored separately. When the servo motor 302 is running, the notch 310 on the partition 308 can be flexibly closed or opened through the cooperation of the transmission wedge 315 and the connecting rod 314, thereby forming one or more compartments. Through the continuous transmission of the servo motor 302 and the intelligent control of the closing assembly, it can be ensured that groundwater samples of different depths will not be confused with each other during the sampling process. When the sampling barrel 300 descends to different depths, the servo motor 302 will first close the lowermost partition 308 to form a compartment to store the groundwater sample of the current depth. Subsequently, as the sampling tube 300 continues to descend and the servo motor 302 operates again, other partitions 308 can be closed in turn to form multiple compartments to store groundwater samples of different depths, and the operations of the two are coordinated with each other.

[0033] Example 3: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: an automatic sampling method based on hydrological surveying and mapping, comprising the following steps: S1. When in use, first operate the driving motor 104 to drive the winding hoist 100 to rotate so that the bracket 200 moves down into the water. At this time, with the cooperation of the gravity ball 105, the bracket 200 can move vertically downward, and the floating plate 103 floats on the water surface for support; S2. When the bracket 200 is swung by a turbulent undercurrent underwater, a certain inclination will be generated. The inclination is derived from the direction of the convection undercurrent. When tilted, the ball 212 facing the undercurrent direction will be driven to roll in the rolling groove 213, and finally the button switch 214 will be resisted to release the electric signal to start the transmission motor 203. The transmission motor 203 drives the driving gear 204 to rotate, thereby driving the first steering idler wheels 205 on both sides to rotate, while driving the second steering idler wheels 206 to rotate, and then driving the transmission gear 207 to rotate. At this time, the two transmission gears 207 rotate in the same direction, so as to move closer to the direction of the second streamline plate 202 respectively. When the driving gear 204 rotates, it will drive the driving wheel 209 to rotate, so as to transmit the two driven wheels 208 to rotate synchronously through the toothed belt 210. At this time, the rotation direction of the driven wheel 208 is the same as that of the driving gear 204 and opposite to that of the two transmission gears 207, so that the second streamline plate 202 and the first streamline plate 201 are closed to each other, so as to form a streamlined structure to resist the undercurrent and reduce the shaking of the bracket 200. S3. When the first streamline plate 201 and the second streamline plate 202 are closed, the crank 402 connected thereto rotates and contacts the contact blocks 401 located on both sides of the bracket 200, so that the contact blocks 401 move to contact the misaligned arc-shaped pieces 405 and drive the connecting rod 403 to rotate, so that the flat plate 400 is closed, and the closing of the first streamline plate 201 and the second streamline plate 202 cooperates with each other to better contact the turbulence; S4. When it is necessary to sample groundwater, the servo motor 302 is started to drive the multiple connecting handles 303 to rotate, so that the offset plate 304 moves in a circle along the center of the sampling tube 300, so that the offset plate 304 is misaligned with the filter hole 301 and cannot block the filter hole 301. At this time, water will flow into the sampling tube 300. At the same time, the servo motor 302 will drive the rotating shaft 311 to rotate on the outer surface of the partition 308 when it is running, so that the transmission wedge 315 in the rotating shaft 311 continuously pushes the connecting rod 314 to move, thereby driving the sealing baffle 312 to approach the groove 310, thereby blocking the partition 308. At the same time, the partition 308 located at the bottom will be blocked first to form a compartment to block groundwater at different depths. Subsequently, the rotating shaft 311 is continuously driven to rotate to intermittently block the partition 308 to form multiple compartments at a time.
