A plurality of silicone integrated heating resistors 2 are fixed side by side on the front face 1 of the main panel, and each test tube is invertedly clamped by the silicone integrated heating resistor 2; a cleaning waste liquid collection tank 6 is placed at the bottom of the front face 1 of the main panel, and the cleaning waste liquid collection tank 6 is directly opposite to the mouth of each test tube; a water pump 10 is connected to the main water pipeline, and a plurality of nozzles 7 are arranged on the main water pipeline, and each nozzle 7 corresponds to the corresponding test tube mouth; the water pump 10 is connected to the main water pipeline, and a plurality of nozzles 7 are arranged on the main water pipeline, and each nozzle 7 corresponds to the corresponding test tube mouth; the water pump 10 is connected to the main water pipeline, and the main water pipeline ...

[0005] However, the water quality monitoring sampling device has the following defects when used specifically:

[0006] 1. When monitoring water quality, the existing water quality monitoring sampling device first performs a water quality sampling operation, and then performs sample monitoring. In addition, when sampling groundwater at different locations, the existing monitored samples are generally discharged, and the groundwater is sampled again. However, in the actual operation of the above scheme, the test tube will sample multiple groups of samples. In the groundwater sampled from the previous group, some dirt adheres to the inner wall of the test tube, affecting the accuracy of sampling and monitoring the next group of groundwater;

[0007] 2. When using existing water quality monitoring sampling devices, in order to facilitate and improve the efficiency of operations, unmanned boats are generally used to carry out continuous sampling operations at different locations. However, traditional unmanned boats travel on groundwater and have to move a long distance. When impurities stick to the inner wall of the sampling tube, the staff needs to spend a long time to move the boat to the shore and then clean the sampling tube, which is inconvenient to operate and inefficient.

[0042] The method for using the groundwater quality monitoring sampling device that is convenient for cleaning dirt provided by the present invention comprises the following steps:

[0043] S1. When monitoring the water quality of groundwater, a sampling tube for sampling is installed on the side of the clamping block, and then the hull with the water quality monitor and the sampling tube installed is placed on the groundwater river channel, and the servo motor drives the propeller to rotate, so that the hull moves in the groundwater river channel;

After that, the monitored hull drives the coupling shaft installed at the output end through the connecting ring through the telescopic cylinder, and moves in the universal ball to adjust the direction and angle of the electric propeller blades on the top of the coupling shaft, so as to freely change the moving direction of the hull;

[0045] S3. When conducting water quality monitoring, the groundwater quality samples stored are collected through the sampling tube, and the content of suspended matter and other impurities in the water quality samples inside the sampling tube are monitored in real time through the monitoring camera to complete the water quality sampling operation. After the monitoring is completed, the water quality samples inside the sampling tube are unloaded through the operation of the DC motor, which is convenient for the subsequent cleaning of the inner wall of the sampling tube and re-sampling;

[0046] S4. When cleaning the sampling tube, the sampling tube is moved to the outside of the cleaning roller brush through the operation of the driving motor. After that, the hull is moved to other positions. When sampling groundwater, the rotational force that drives the propeller to rotate will drive the rotating shaft and the cleaning roller brush to rotate through the first synchronous belt, the driven shaft and the second synchronous belt, thereby completing the automatic cleaning of the dirt on the inner wall of the sampling tube.

[0047] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0048] 1. The groundwater quality monitoring sampling device and the use method thereof, which are convenient for cleaning dirt, start the servo motor to operate when sampling groundwater, and drive the driving shaft connected to the output end of the servo motor, the first bevel gear connected to the bottom of the driving shaft through the gear accelerator, the second bevel gear meshingly connected to the side of the first bevel gear, and the spiral shaft and propeller installed inside the second bevel gear to operate, so as to drive the hull to move and change the position for sampling groundwater. At the same time, when the hull moves, it can synchronously drive the first synchronous belt connected to the outside of the driving shaft through the synchronous wheel, the driven shaft connected to the inside of the first synchronous belt through the synchronous wheel, the second synchronous belt connected to the top of the driven shaft through the synchronous wheel, the rotating shaft connected to the inside of the second synchronous belt through the synchronous wheel, and the cleaning roller brush to operate, so as to automatically clean the inner wall of the sampling tube for sampling, and ensure that the inner wall of the sampling tube will not be adhered to dirt, and the efficiency is high;

[0049] 2. The groundwater quality monitoring sampling device and its use method, which are convenient for cleaning dirt, clamp and fix the sampling tube for sampling by means of a servo motor driving the output end threaded rod, and the threaded rod driving the outer threaded connection telescopic block and the clamping block to move, so as to facilitate the subsequent automated water quality sampling operation. When sampling is actually performed, the reciprocating screw rod and the lifting block at the output end can be driven by a driving motor to operate, so that the sampling tube can be moved to below the groundwater surface for sampling. At the same time, after the sampling is completed, it can be moved to the water surface, which is convenient for the monitoring operation of the monitoring camera. The reciprocating screw rod that drives the sampling tube to move up and down can also move the sampling tube to the outside of the cleaning roller brush after completing one monitoring, so as to facilitate the subsequent automatic cleaning of the inner wall of the sampling tube.

[0050] 3. The groundwater quality monitoring sampling device and its use method, which are convenient for cleaning dirt, can adjust the direction and angle of the electric screw blades on the top of the coupling shaft by driving the output end connecting ring and the coupling shaft to rotate in the universal ball through the telescopic cylinder when sampling the groundwater quality. The angle and direction of the movement of the hull on the water surface can be changed through the design of the electric screw blades, so as to facilitate sampling at different positions of the river.

[0051] 4. The groundwater quality monitoring sampling device and the use method thereof, which are easy to clean dirt, when monitoring the groundwater sample stored in the sampling tube, the clamping block for clamping and fixing the sampling tube can adjust the direction and angle of the inner sampling tube by rotating the clamping block driven by a DC motor, so as to ensure that the sampling tube can be set obliquely when monitored by a monitoring camera, thereby improving the monitoring accuracy. At the same time, after the sampling tube is rotated to 90 degrees, the sample inside the sampling tube can be automatically discharged, so as to facilitate the next sampling of water quality samples.

[0076] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0077] See also Figure 1-Figure 12, a groundwater quality monitoring sampling device that is convenient for cleaning dirt, includes a hull 10, a water quality monitor 20, a head-mounted camera 30, a propeller 40, a lifting and clamping assembly 50, a hull deflection assembly 60 and an automatic cleaning mechanism 70, wherein one side of the top of the hull 10 supports the water quality monitor 20, the side of the water quality monitor 20 is installed with the head-mounted camera 30, the back of the hull 10 is provided with a propeller 40, and the propeller 40 is driven by the automatic cleaning mechanism 70; wherein, lifting and clamping assemblies 50 are installed on the left and right sides of the hull 10, a sampling barrel 5001 is installed on the inner side of the lifting and clamping assembly 50, and hulls installed on the sides of the hull 10 are provided on both sides of the lifting and clamping assembly 50 The deflection assembly 60 and the automatic cleaning mechanism 70 include an acceleration drive assembly 80, which is mounted on the side of the hull 10 and is connected to a propeller 40 at the bottom, and is mounted on the back of the water quality monitor 20; a rotating cleaning assembly 90, which is mounted on the left and right sides of the acceleration drive assembly 80 and is located on the top of the hull 10, and is driven by the acceleration drive assembly 80 to clean dirt from the sampling tube 5001; wherein the water quality monitor 20 monitors the water quality inside the sampling tube 5001 through a monitoring camera 201, and the monitoring camera 201 is mounted on the top of the lifting and clamping assembly 50.

[0078] The above working principle: when monitoring the groundwater quality, first move the sampling tube 5001 for sampling the groundwater to the side of the lifting and clamping assembly 50, and complete the installation and fixation of the sampling tube 5001 through the lifting and clamping assembly 50. Then, when sampling, place the hull 10 in the river channel of the groundwater, and start the acceleration drive assembly 80 through the control end to drive the hull 10 to move to the position corresponding to the groundwater sampling. Then, when sampling, the lifting and clamping assembly 50 can extend the sampling tube 5001 below the water surface, and complete the collection of water quality samples through the sampling tube 5001. When the water quality is collected, the lifting and clamping assembly 50 raises the sampling tube 5001 above the water surface, and uses the monitoring camera 201 to shoot the monitoring Measure and complete the monitoring operation of the content of impurities or other substances in the groundwater. After completing the above operations, the lifting and clamping assembly 50 can pour out the sample and perform sampling operations at other groundwater river locations. At this time, when the hull 10 moves to other locations in the river, the acceleration drive assembly 80 will drive the rotating cleaning assembly 90 to operate while operating, and rotate and clean the sampling tube 5001 moved to the outside of the rotating cleaning assembly 90 to remove dirt and impurities adhered to the inner wall of the sampling tube 5001, thereby improving the effect and accuracy of subsequent monitoring of groundwater samples. Among them, the design of the hull deflection assembly 60 allows the hull 10 to deflect in multiple directions and angles, which is convenient for the hull 10 to move to different locations for sampling and monitoring operations.

[0079] In the above scheme, sampling and monitoring of groundwater can be carried out continuously without the need for transportation, which is more convenient.

[0080] Specific reference Figure 7 , Figure 8 and Fig.12 The lifting and clamping assembly 50 includes a connecting frame 501, which is welded at the center of the left and right sides of the hull 10. The internal rotation of the connecting frame 501 is connected to a reciprocating screw rod 502, which is connected to the output end of the driving motor 503, and the driving motor 503 is installed on the top of the connecting frame 501 through an external protective seat 504; a lifting block 505, which is connected to the outer side of the reciprocating screw rod 502 through a ball bearing and is slidably connected to the connecting frame 501, and a mounting frame 506 is installed on the side of the lifting block 505; a servo motor 507, which is installed on one side of the mounting frame 506, and a threaded rod 508 is connected to the output end of the servo motor 507, and the threaded rod 508 is provided in two groups and connected to each other; a telescopic block 509, which is threadedly connected to the outer side of the threaded rod 508 and slidably connected to the side of the mounting frame 506, and the side of the telescopic block 509 is rotatably connected to a clamping block 5010.

[0081] In this embodiment, reinforcement frames 5051 are installed on the left and right sides of the lifting block 505, and a mounting frame 506 is fixedly installed on the inner side of the reinforcement frame 5051. The top of the mounting frame 506 supports a monitoring camera 201. By designing the position of the monitoring camera 201, the monitoring camera 201 can monitor the sampling tube 5001 in real time.

[0082] Meanwhile, in this embodiment, the thread directions of the two groups of threaded rods 508 are opposite. Through the design of the threaded rods 508 , the movement directions of the two groups of telescopic blocks 509 are opposite, thereby achieving the clamping and fixing of the sampling tube 5001 .

[0083] Moreover, in the present embodiment, a DC motor 5011 is installed on the other side of the telescopic block 509, and the output end of the DC motor 5011 is connected to a clamping block 5010; wherein, the clamping block 5010 clamps and fixes the sampling tube 5001, and through the design of the DC motor 5011, after the monitoring of the groundwater is completed, the sampling tube 5001 can be rotated to automatically discharge the sample, which is convenient for the next sampling of water quality samples at other positions, and, when conducting water quality monitoring, the position of the sampling tube 5001 can be rotated by the control of the DC motor 5011, which is more convenient for the monitoring camera 201 to sample and monitor the water quality inside the sampling tube 5001.

[0084] The groundwater quality monitoring sampling device of the present invention, which is easy to clean dirt, moves the sampling tube 5001 for sampling to the side of the clamping block 5010 when sampling groundwater. Then, the servo motor 507 is started by the controller to operate, driving the threaded rod 508 connected to the output end of the servo motor 507 to rotate.

At this time, when the sampling tube 5001 is extended to below the groundwater surface, the water quality sampling operation can be completed. When monitoring, the sampling tube 5001 is moved to the water surface. When the inner wall of the sampling tube 5001 is cleaned, the sampling tube 5001 is moved to the outside of the rotating cleaning component 90.

[0086] The groundwater quality monitoring sampling device of the present invention, which is easy to clean dirt, can drive the output end connecting ring 604 to operate through the telescopic cylinder 605 when changing the position for water quality sampling, thereby driving the connecting shaft 602 installed on the inner side of the connecting ring 604 to rotate on the universal ball 601, thereby changing the direction and angle of the electric propeller blades 603 connected to the top of the connecting shaft 602, and changing the direction and angle of the movement of the hull 10 on the water surface.

[0087] Specific reference Fig.10 and Fig.11The acceleration drive assembly 80 includes a motor base 801, which is installed on the top of the hull 10 and located on the side of the water quality monitor 20. The top of the motor base 801 supports a servo motor 802, and the output end of the servo motor 802 is connected to a drive shaft 803; wherein the drive shaft 803 is arranged through the hull 10, and the drive shaft 803 is connected to the input end of a gear accelerator 804, and the gear accelerator 804 is installed at the bottom of the hull 10; a first bevel gear 805, which is installed on the side of the output end of the gear accelerator 804 and is rotatably connected to the top of a support block 8051, and the support block 8051 is installed at the bottom of the hull 10; a second bevel gear 806, which is meshed and connected to the side of the first bevel gear 805 and is rotatably connected to the side of the hull 10, and a spiral shaft 807 is installed inside the second bevel gear 806.

[0089] At the same time, in this embodiment, two sets of rotating cleaning components 90 are installed on the outer side of the driving shaft 803, and the gear accelerator 804 accelerates the rotation of the driving shaft 803 through the internal gear group; wherein, the first bevel gear 805 and the second bevel gear 806 are relatively vertically arranged, and have the same structure size, and the design of the driving shaft 803 can drive the rotating cleaning component 90 to operate while driving the first bevel gear 805 and the second bevel gear 806 to rotate.

[0090] The groundwater quality monitoring sampling device that is easy to clean dirt of the present invention can drive the hull 10 to move and sample the groundwater at a specific location by starting the servo motor 802 through the controller, driving the drive shaft 803 connected to the output end of the servo motor 802 to rotate. At this time, the rotation of the drive shaft 803 will drive the first bevel gear 805 installed at the bottom thereof to rotate, thereby driving the second bevel gear 806 meshingly connected to the side of the first bevel gear 805 to rotate. When the second bevel gear 806 rotates, it will drive the spiral shaft 807 installed inside thereof to rotate, so that the propeller 40 connected to the bottom of the spiral shaft 807 rotates, thereby pushing the hull 10 to move. The force of the rotation of the drive shaft 803 can accelerate the rotation speed of the propeller 40 through the acceleration of the gear accelerator 804, thereby increasing the speed of the hull 10 when moving on the river channel.

[0091] Specific reference Fig.10 and Fig.12The rotating cleaning component 90 includes a first synchronous belt 901, which is connected to the outer side of the driving shaft 803 through a synchronous wheel arranged on the inner side, and is movably connected to the top of the hull 10. The inner side of the first synchronous belt 901 is also connected to a driven shaft 902 through a synchronous wheel, and the driven shaft 902 is arranged away from the driving shaft 803; a second synchronous belt 903, which is connected to the top of the driven shaft 902 through a synchronous wheel arranged on the inner side, and the inner side of the second synchronous belt 903 is also connected to a rotating shaft 904 through a synchronous wheel, and the rotating shaft 904 is rotatably connected to the inside of a bracket 9041, and the bracket 9041 is installed on the top of the protective seat 504; a cleaning roller brush 905, which is connected to the bottom of the rotating shaft 904, and extends to the inside of the sampling tube 5001, and cleans the dirt of the sampling tube 5001.

[0092] In this embodiment, the first synchronous belt 901 on the left side is higher than the first synchronous belt 901 on the right side, and the driven shaft 902 is rotatably connected to the side of the positioning frame 9021. The positions of the two sets of first synchronous belts 901 can be designed so that when the two sets of first synchronous belts 901 rotate under the drive of a set of driving shafts 803, there will be no conflict between the two.

[0093] Meanwhile, in the present embodiment, the positioning frame 9021 is installed on the top of the hull 10 , and the top of the positioning frame 9021 is movably connected with the second synchronous belt 903 . The design of the positioning frame 9021 can support the operation of the driven shaft 902 and the second synchronous belt 903 .

[0094] The groundwater quality monitoring sampling device of the present invention, which is easy to clean dirt, will drive the first synchronous belt 901 connected to the outside through the synchronous wheel to operate when the driving shaft 803 rotates, and then drive the driven shaft 902 connected to the inside of the first synchronous belt 901 through the synchronous wheel to rotate. After that, the rotation of the driven shaft 902 will drive the second synchronous belt 903 connected to the top through the synchronous wheel to move, and then drive the rotating shaft 904 connected to the inside of the second synchronous belt 903 through the synchronous wheel to rotate. After that, when the rotating shaft 904 rotates, it will drive the cleaning roller brush 905 connected to the bottom to rotate, and clean the inner wall of the sampling tube 5001 arranged on the outside of the cleaning roller brush 905.

[0095] See also Figure 1-Figure 12 The method for using a groundwater quality monitoring sampling device that is convenient for cleaning dirt comprises the following steps:

[0096] S1. When monitoring the water quality of groundwater, the sampling tube 5001 for sampling is installed on the side of the clamping block 5010, and then the hull 10 with the water quality monitor 20 and the sampling tube 5001 installed is placed on the river channel of groundwater, and the servo motor 802 drives the propeller 40 to rotate, so that the hull 10 moves in the river channel of groundwater;

[0097] S2. After that, the monitored hull 10 drives the connecting shaft 602 installed at the output end through the connecting ring 604 through the telescopic cylinder 605, and moves in the universal ball 601 to adjust the direction and angle of the electric propeller blade 603 on the top of the connecting shaft 602, so as to freely change the moving direction of the hull 10;

[0098] S3. When monitoring water quality, the groundwater samples are collected and stored through the sampling tube 5001. The content of impurities such as suspended matter in the water samples inside the sampling tube 5001 is monitored in real time through the monitoring camera 201 to complete the water quality sampling operation. After the monitoring is completed, the water samples inside the sampling tube 5001 are unloaded through the operation of the DC motor 5011, which is convenient for the subsequent cleaning of the inner wall of the sampling tube 5001 and re-sampling;

[0099] S4. When cleaning the sampling tube 5001, the sampling tube 5001 is moved to the outside of the cleaning roller brush 905 through the operation of the driving motor 503. After that, the hull 10 is moved to other positions. When sampling groundwater, the rotational force that drives the propeller 40 to rotate will drive the rotating shaft 904 and the cleaning roller brush 905 to rotate through the first synchronous belt 901, the driven shaft 902 and the second synchronous belt 903, thereby completing the automatic cleaning of the dirt on the inner wall of the sampling tube 5001.
