Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a water environment treatment sampling device. Background Art

[0002] Water quality sampling is a very important part of the environmental monitoring and water treatment industry. It is used to assess water quality, monitor water pollution, ensure drinking water safety, and conduct scientific research. Water quality sampling involves a series of steps and precautions to ensure that the water samples obtained can accurately reflect the true situation of the water quality. When sampling still waters, due to the poor fluidity of still waters, the samples at each point in the water cannot represent the entire water area. Sampling at multiple points is required to more accurately understand the situation of the entire water area.

[0003] The existing method is to use a water pump or other means to pump water into a collection bucket when sampling some static water areas. After sampling one point, the next point is sampled. However, when sampling the next point, water from the previous point still remains in the pipeline. When sampling the next point, the remaining water will enter the collection bucket together, thus affecting the water samples of subsequent points, and thus the water quality of each point in the entire water area is inaccurate.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with specific embodiments.

[0034] When the existing sampling device is sampling at multiple points, water will remain in the pipeline. When sampling the next point, the residual water will enter the collection bucket, which will affect the water samples of subsequent points and lead to inaccurate understanding of the water quality of each point in the entire water area.

A first fixed plate 11 is fixedly connected to the front side of the shell 1. Six evenly distributed second fixed plates 12 are fixedly connected to the rear side of the first fixed plate 11. A water collecting shell 13 is slidably connected between two adjacent second fixed plates 12. The water collecting shell 13 is used to collect the taken water samples. A spring is provided between the water collecting shell 13 and the shell 1. The spring is used to reset the adjacent water collecting shell 13. When the sampling is completed and the water in the water collecting shell 13 is taken out, the water collecting shell 13 returns to its original position under the action of the adjacent springs. Both water inlets of the peristaltic pump 7 are provided with hoses. The hose on the rear side is connected to the hard tube 10, and the hose on the front side is located above the water collecting shell 13 away from the side of the peristaltic pump 7.

[0036] like Figure 2-Figure 4 and Figure 6-Figure 9 As shown, a third fixed plate 14 is fixedly connected in the shell 1, and the third fixed plate 14 is slidably connected with a first sliding block 15. A tension spring is arranged between the first sliding block 15 and the third fixed plate 14. The tension spring is initially in a power storage state, and is used to move the first sliding block 15 upward. A first mounting frame 16 is fixedly connected to the rear side of the first sliding block 15. The first mounting frame 16 consists of a round rod and an L-shaped plate. The left side of the L-shaped plate portion of the first mounting frame 16 is rotatably connected with a second rotating shaft 17. The second rotating shaft 17 is fixedly connected with a fifth transmission wheel 18. The fifth transmission wheel 18 is a friction material. The fifth transmission wheel 18 is matched with the second transmission wheel 5 for transmission. A first gear box 19 is arranged in the shell 1. The first gear box 19 is a three-axis gear box, in which the first axis (i.e. the axis on the left side) and the second rotating shaft 17 are transmitted through a telescopic universal joint and a bevel gear set, and the second axis (i.e. the axis on the upper right side) and the first transmission shaft 8 are transmitted through a bevel gear set.

[0037] like Figure 2-Figure 8As shown, a second gear box 20 is arranged in the shell 1, and the input shaft of the second gear box 20 is fixedly connected with the sixth transmission wheel 21, the sixth transmission wheel 21 is a friction material, and the sixth transmission wheel 21 is in transmission cooperation with the second transmission wheel 5, and the output shaft of the second gear box 20 is fixedly connected with the third transmission shaft 22, and an interlayer is arranged on the lower side of the shell 1, and the third transmission shaft 22 is located in the interlayer, and the third transmission shaft 22 is rotatably connected with the shell 1 and passes through the right side of the shell 1, and three blades 23 evenly distributed in the circumferential direction are arranged on the right side of the third transmission shaft 22, and a sliding frame 24 is slidably connected in the shell 1, and the sliding frame 24 is rotatably connected with the first transmission wheel 4, and an extrusion rod 25 is fixedly connected to the front side of the sliding frame 24, and a roller is rotatably connected to the round rod portion of the first mounting frame 16, and the extrusion rod 25 is extrusion-matched with the roller on the first mounting frame 16.

[0038] like Figure 8-Figure 10 As shown, a fixed rod 26 is fixedly connected in the housing 1, and the fixed rod 26 is slidably connected with a second sliding block 27 that slides left and right. A tension spring is arranged between the second sliding block 27 and the sliding frame 24, and the tension spring is used to pull the sliding frame 24 to move rightward. The third shaft of the first gear box 19 (i.e., the shaft at the lower right side) is fixedly connected with a rope winding wheel 28. When the first shaft of the first gear box 19 rotates counterclockwise from the front view, the second shaft rotates counterclockwise, and the third shaft rotates clockwise. When the first shaft rotates clockwise from the front view, the second shaft rotates clockwise, and the third shaft rotates counterclockwise. A thin rope is wound around the rope winding wheel 28, and the thin rope is fixedly connected to the second sliding block 27. The rope winding wheel 28 winds up the thin rope to pull the second sliding block 27 to move rightward. A U-shaped first transmission rod 29 is slidably connected in the housing 1, and a tension spring is arranged between the first transmission rod 29 and the sliding frame 24. The tension spring is used to pull the sliding frame 24 to move leftward.

[0039] like Fig.10 and Fig.11 As shown, a second mounting frame 30 is fixedly connected in the shell 1, and the second mounting frame 30 is slidably connected with a spring rod 31. A spring is arranged between the fixed part of the spring rod 31 and the shell 1, and the spring is used to reset the spring rod 31. The fixed part of the spring rod 31 is fixedly connected with an extrusion block 32. A roller is rotatably connected to the side of the first transmission rod 29 close to the extrusion block 32. The extrusion block 32 is extruded and matched with the roller on the first transmission rod 29. The telescopic end of the spring rod 31 is rotatably connected with a roller. The roller at the telescopic end of the spring rod 31 is extruded and matched with the adjacent second fixed plate 12 and the adjacent water collecting shell 13. As the water in the water collecting shell 13 increases, the water collecting shell 13 moves downward and squeezes the roller at the telescopic end of the spring rod 31, so that the spring rod 31 moves downward.

[0040] like Fig. 9As shown, a mounting rod 241 is fixedly connected in the shell 1, and the front side of the mounting rod 241 is slidably connected to a limiting column 242. A spring is arranged between the limiting column 242 and the mounting rod 241, and the spring is used to enable the limiting column 242 to limit the sliding frame 24. The sliding frame 24 is provided with two evenly distributed grooves, and the limiting column 242 is limitedly matched with the adjacent grooves. When the limiting column 242 is inserted into the adjacent groove, the movement of the sliding frame 24 needs to overcome the resistance of the limiting column 242.

[0041] like Fig.10 As shown, an L-shaped first sliding rod 33 is slidably connected to the upper side of the first fixed plate 11, a telescopic rod 34 is fixedly connected to the telescopic portion of the spring rod 31, and the telescopic end of the telescopic rod 34 is fixedly connected to the first sliding rod 33. The telescopic rod 34 is used to drive the first sliding rod 33 to drive the water outlet of the adjacent hose to move when the telescopic end of the spring rod 31 moves to the left, and the hose on the front side of the peristaltic pump 7 is fixedly connected to the first sliding rod 33 and passes through it.

[0042] When using the device, place the device in the water area where sampling is required, and then start the motor 2. The output shaft of the motor 2 drives the spline shaft 3 to rotate counterclockwise from the left view, and the spline shaft 3 drives the first transmission wheel 4 to rotate. The first transmission wheel 4 drives the second transmission wheel 5 to rotate through friction. The second transmission wheel 5 drives the sixth transmission wheel 21 to rotate through friction. The sixth transmission wheel 21 drives the third transmission shaft 22 to rotate through the second gear box 20. The third transmission shaft 22 drives three blades 23 to rotate. The blades 23 pry water and push the housing 1 to move. At the same time, the second transmission wheel 5 drives the fifth transmission wheel 18 to rotate clockwise from the left view. The driving wheel 18 drives the second rotating shaft 17 to rotate, and the second rotating shaft 17 drives the second shaft and the third shaft of the first gear box 19 to rotate through the adjacent bevel gear set and the telescopic universal joint. The second shaft of the first gear box 19 drives the first transmission shaft 8 to rotate counterclockwise from the left view direction through the adjacent bevel gear set, and the first transmission shaft 8 drives the peristaltic pump 7 to work. At this time, the peristaltic pump 7 draws water from the hose adjacent to the first sliding rod 33 into the peristaltic pump 7, and then enters the hose adjacent to the hard tube 10 from the peristaltic pump 7 and then enters the hard tube 10, thereby discharging the water. However, there is no water in the hose adjacent to the first sliding rod 33 at this time, so the peristaltic pump 7 just pumps the air, and at the same time, the third shaft of the first gear box 19 drives the rope wheel 28 to rotate clockwise, and the rope wheel 28 gradually retracts the thin rope, and the thin rope pulls the second sliding block 27 to move rightward, and the second sliding block 27 moves to the right and stretches the adjacent tension spring. As the tension spring adjacent to the second sliding block 27 is gradually stretched, the tension of the tension spring on the sliding frame 24 gradually increases. When the tension reaches a certain level, the sliding frame 24 moves to the right and squeezes the limiting column 242, and the limiting column 242 moves backward and compresses the adjacent spring. When the limiting column 242 is separated from the adjacent groove, the sliding frame 24 loses the limiting force of the limiting column 242. The first mounting frame 16 is moved to the right position and quickly moves to the right. The sliding frame 24 drives the first transmission wheel 4 to move to the right until it contacts the third transmission wheel 6. At this time, the limiting column 242 is inserted into the groove on the left side of the sliding frame 24 under the action of the adjacent spring. When the sliding frame 24 moves, the sliding frame 24 drives the extrusion rod 25 to move. The extrusion rod 25 gradually releases the extrusion of the roller on the first mounting frame 16. The first sliding block 15 drives the first mounting frame 16 to move upward under the action of the adjacent tension spring. The first mounting frame 16 drives the second rotating shaft 17 to move upward. The second rotating shaft 17 drives the fifth transmission wheel 18 to move upward, and the fifth transmission wheel 18 is separated from the second transmission wheel 5.

[0043] When the first transmission wheel 4 contacts the third transmission wheel 6, the first transmission wheel 4 drives the third transmission wheel 6 to rotate counterclockwise from the left view, the blade 23 stops rotating, the third transmission wheel 6 drives the fourth transmission wheel 9 to rotate clockwise from the left view through friction, and the fourth transmission wheel 9 drives the peristaltic pump 7 to rotate in the opposite direction through the first transmission shaft 8. At this time, the peristaltic pump 7 sucks water from the hard tube 10, then enters the hard tube 10 through the soft tube, and then enters the adjacent water collecting shell 13 from another soft tube. The water in the water collecting shell 13 gradually increases, and the water collecting shell 13 is sucked out. The water shell 13 moves downward and compresses the adjacent spring, and the water collecting shell 13 squeezes the telescopic end of the spring rod 31, so that the spring rod 31 moves downward and compresses the adjacent spring. When the roller at the telescopic end of the spring rod 31 is lower than the lower side of the second fixed plate 12, the output end of the spring rod 31 drives the adjacent roller to move leftward. When the roller at the telescopic end of the spring rod 31 separates from the adjacent second fixed plate 12, the telescopic end of the spring rod 31 drives the telescopic rod 34 to move leftward, and the telescopic rod 34 drives the water outlet of the adjacent hose to move through the first sliding rod 33. When the roller at the telescopic end of the spring rod 31 is separated from the adjacent second fixed plate 12, the spring rod 31 moves upward under the action of the adjacent spring. When the roller at the telescopic end of the spring rod 31 contacts the right side of the next second fixed plate 12, the telescopic end of the spring rod 31 stops moving to the left. The spring rod 31 moves upward under the action of the adjacent spring until the roller at the telescopic end of the spring rod 31 contacts the lower side of the new water collecting shell 13. When the first transmission wheel 4 drives the third transmission wheel 6 to rotate, the third transmission wheel 6 drives the first transmission shaft 8 to rotate through the fourth transmission wheel 9, and the first transmission shaft 8 drives the second shaft of the first gear box 19 to rotate through the adjacent bevel gear set. At this time, the second shaft of the first gear box 19 drives the third shaft to reverse as the input shaft, and the third shaft drives the rope wheel 28 to reverse, so that the rope wheel 28 releases the thin rope wound thereon. At this time, the first shaft of the first gear box 19 reverses, but because the fifth transmission wheel 18 is separated from the second transmission wheel 5, the second transmission wheel 5 does not rotate.

[0044] When the spring rod 31 moves downward, the spring rod 31 drives the extrusion block 32 to move downward, and the extrusion block 32 squeezes the roller on the first transmission rod 29, so that the first transmission rod 29 moves to the left. When the first transmission rod 29 moves to the left, it stretches the adjacent tension spring. As the tension spring is gradually stretched, the tension of the tension spring on the sliding frame 24 gradually increases. When the resistance of the limiting column 242 to the sliding frame 24 is not enough to keep the sliding frame 24 stationary, the tension spring adjacent to the first transmission rod 29 pulls the sliding frame 24 to move to the left, and the sliding frame 24 squeezes the limiting column 242 to move it backward and compress the adjacent spring. When the limiting column 242 is separated from the adjacent groove on the sliding frame 24, the sliding frame 24 moves quickly to the left. When the sliding frame 24 moves, it drives the first transmission wheel 4 to move to the left, so that the first transmission wheel 4 Separated from the third transmission wheel 6, when the sliding frame 24 moves to the left, the sliding frame 24 drives the squeezing rod 25 to move to the left, and the squeezing rod 25 squeezes the roller of the first mounting frame 16. The first mounting frame 16 is squeezed and drives the first sliding block 15, the second rotating shaft 17 and the fifth transmission wheel 18 to move downward. When the first sliding block 15 moves downward, the adjacent tension spring is stretched, and the fifth transmission wheel 18 moves downward until it is released from the second transmission wheel 5 and then stops moving. At this time, the first transmission wheel 4 contacts the second transmission wheel 5. At this time, the peristaltic pump 7 returns to the initial rotation direction again, thereby discharging the water in the hose to prevent the water from the previous sampling point from entering the next sampling point. At the same time, the housing 1 continues to move to the next sampling point. The above steps are repeated. When the sampling is completed, the device can be taken out of the water.

[0045] Most existing sampling devices can only sample water at a fixed depth and cannot adjust the sampling depth, resulting in the samples obtained being unrepresentative.

[0046] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Fig.12 As shown, it also includes an adjustment shell 35, which is fixed in the shell 1. The adjustment shell 35 and the shell 1 are both slidably connected to the hard tube 10. The sampling depth can be adjusted by moving the hard tube 10 up and down. The adjustment shell 35 is threadedly connected to a threaded rod 36, and the threaded rod 36 is squeezed and matched with the hard tube 10. When the sampling depth is adjusted, the threaded rod 36 is tightened to squeeze the hard tube 10, thereby fixing the hard tube 10.

[0047] Before using the device, the sampling depth is adjusted as needed. When adjusting the sampling depth, the threaded rod 36 is rotated to separate the threaded rod 36 from the hard tube 10, and then the hard tube 10 is moved up and down to make the lower side of the hard tube 10 located at the predetermined sampling depth, and then the threaded rod 36 is rotated again to make the threaded rod 36 clamp the hard tube 10, thereby fixing the hard tube 10.

[0048] When existing sampling devices take samples at different points, the distance between the sampling points is usually measured manually before taking samples. This method is too inefficient.

[0049] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 2 and Fig.13 As shown, it also includes a sliding ring 37, which is slidably connected to the right side of the third transmission shaft 22. The blade 23 is rotatably connected to the third transmission shaft 22. The thrust generated when the blade 23 rotates can be adjusted by rotating the blade 23 and changing the angle between the blade 23 and the third transmission shaft 22. The left side of the sliding ring 37 is ball-connected with three second transmission rods 38 evenly distributed circumferentially, and the second transmission rod 38 is ball-connected with the adjacent blade 23.

[0050] like Figure 1 , Figure 2 and Fig.13 As shown, the sliding ring 37 is slidably connected to the limiting block 39, and a spring is arranged between the limiting block 39 and the sliding ring 37, and the spring is used to reset the limiting block 39. A second sliding rod 40 is fixedly connected to the upper side of the limiting block 39, and the second sliding rod 40 is used to release the limiting of the sliding ring 37 by the limiting block 39. The second sliding rod 40 is slidably connected to the sliding ring 37 and penetrates it. The third transmission shaft 22 is provided with seven evenly distributed limiting grooves, and the limiting block 39 is limitedly matched with the adjacent limiting grooves. When the limiting block 39 is inserted into the adjacent limiting groove, the sliding ring 37 cannot move.

[0051] Before using the device, the sampling interval is adjusted as needed. When adjusting the sampling interval, the second sliding rod 40 is pulled upward, and the second sliding rod 40 drives the limit block 39 to move upward and compress the adjacent spring. After the limit block 39 is separated from the adjacent limit groove, the sliding ring 37 is pulled left and right, and the sliding ring 37 drives the three blades 23 to rotate through the three second transmission rods 38, thereby adjusting the angle of the blade 23. When the angle of the blade 23 changes, the speed of the device moving in the water changes, and the time interval of the movement of the sliding frame 24 remains unchanged, thereby changing the distance when the device stops moving, thereby adjusting the sampling interval. After the adjustment is completed, the second sliding rod 40 is released, and the limit block 39 and the second sliding rod 40 move downward under the action of the adjacent springs and are inserted into the adjacent limit groove, thereby fixing the sliding ring 37.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
