[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 4As shown, an environmental monitoring water quality sampling device described in an embodiment of the present invention includes a buoy 1; a through groove 2 is opened in the middle of the buoy 1; the top surface of the buoy 1 is fixedly connected to a support frame 3; a suction pipe 4 is installed near the top position inside the support frame 3; a suction pump 5 is fixedly connected to the top of the support frame 3; the top surface of the suction pump 5 is fixedly connected to a discharge pipe 401, and the discharge pipe 401 passes through the top of the support frame 3; a collection tank 6 is provided inside the support frame 3; two pairs of symmetrically arranged solar panels 7 are fixedly connected to the outside of the support frame 3; the solar panels 7 are connected to the battery through wires, and the battery is connected to the suction pump 5 through wires; a plurality of evenly arranged chains 8 are installed at the bottom of the buoy 1; a counterweight block 801 is commonly fixed to the bottom surface of a plurality of the chains 8; when working, in order to facilitate long-term monitoring of a designated water area, the embodiment of the present invention can be used. First, the deployment of the embodiment of the present invention requires the user to connect multiple embodiments of the present invention After moving to the designated waters by boat, the user places the embodiment of the present invention in different areas of the designated waters. At this time, the buoy 1 will float on the water surface under the action of its own buoyancy, and the counterweight block 801 will sink to the bottom of the water due to gravity. At this time, the chain 8 between the counterweight block 801 and the buoy 1 can limit the position of the buoy 1 so that it is always on the top surface of the counterweight block 801, thereby enabling the embodiment of the present invention to be fixed in the designated waters for a long time. Thereafter, whenever the user needs to go to the designated waters to obtain water samples, the user can start the suction pump 5 in advance by remote control to allow the suction tube 4 to draw water samples from the bottom of the groove 2. The sucked water samples then pass through the suction pump 5 and are discharged from the discharge tube 401 and enter the collection tank 6. Therefore, when the user arrives, he only needs to replace the collection tank 6 to complete the water sampling operation, and the user no longer needs to perform a collection operation every time he arrives at an area, thereby improving the efficiency of water sample collection.

[0023] like Figures 1 to 3 As shown, the inner wall of the through groove 2 is fixed with a plurality of evenly arranged sliding rods 9; the bottom surfaces of the plurality of sliding rods 9 are commonly fixed with a connecting ring 10; the density of the sliding rods 9 and the connecting ring 10 are both less than that of water; the chain 8 is evenly fixed to the bottom surface of the connecting ring 10; during operation, when the water level in the water area where the embodiment of the present invention is located rises due to precipitation or other factors, the sliding rods 9 on the inner wall of the through groove 2 will slide relative to the buoy 1, so that the sliding rods 9 and the connecting ring 10 can move below the water surface, so that the buoy 1 can continue to float up, and then adapt to the rising water surface, to avoid the embodiment of the present invention being submerged by the water surface due to the rising water surface and the unchanged length of the chain 8.

[0024] like Figures 1 to 4As shown, the bottom surface of the top of the support frame 3 is rotatably connected to a driving tube 11; the driving tube 11 is driven by a servo motor and connected to a battery; the surface of the driving tube 11 is slidably connected to a sleeve 12; the outer side of the sleeve 12 is threadedly connected to a fixed tube 13, and the fixed tube 13 is fixedly connected to the top of the support frame 3; the top of the sleeve 12 is rotatably connected to a sliding tube 14; the inner thread of the sleeve 12 is connected to a top tube 15; the top of the top tube 15 is fixedly connected to a sliding tube 2 16; the sliding tube 14 is slidably connected to the inner side of the sliding tube 2 16; the side of the suction tube 4 away from the suction pump 5 is fixedly connected to a telescopic tube; the end of the telescopic tube away from the suction tube 4 is fixedly connected to the bottom of the top tube 15; during operation, in order to facilitate the user to collect water samples at different depths, the user can remotely control Or the collection program can be set in advance so that the servo motor drives the driving tube 11 to rotate, and the rotating driving tube 11 drives the sleeve 12 to rotate. Since the sleeve 12 is threadedly connected to the fixed tube 13, the sleeve 12 drives the sliding tube 14 connected to it to move in the direction away from the suction pump 5. Since the sleeve 12 is threadedly connected to the top tube 15, and the top tube 15 is fixedly connected to the sliding tube 2 16, the top tube 15 will also move in the direction away from the suction pump 5, thereby achieving relative sliding between the sliding tube 14, the sliding tube 2 16 and the fixed tube 13, thereby achieving the effect of driving the bottom of the telescopic tube to penetrate into different depths underwater, thereby facilitating the user's operation of sampling water bodies at different depths, so that the user can have a more comprehensive understanding of the water quality of the specified water area.

[0025] like Figures 4 and 5 As shown, the telescopic tube includes a plurality of evenly arranged bellows 17; connecting tubes 18 are fixedly connected between the bellows 17 and at the ends of the bellows 17 away from each other; the connecting tube 18 at the top is fixedly connected to the suction pipe 4, and the connecting tube 18 at the bottom is fixedly connected to the bottom of the top pipe 15; a pair of symmetrically arranged slides 19 are fixedly connected to the surface of the connecting tube 18 located inside the top pipe 15 and the driving pipe 11, and the slides 19 are slidably connected to the inner walls of the top pipe 15 and the driving pipe 11; during operation, when the slide tube 14 and the slide tube 2 16 slide in the direction away from the suction pipe 4, the slide tube 14 will pull The connecting pipe 18 at the bottom is moved, and then the connecting pipe 18 will pull the bellows 17, so that the bellows 17 can be stretched. At the same time, the connecting pipes 18 between the bellows 17 will also slide inside the top pipe 15 and the driving pipe 11 through the slide plate 19. When the tube one and the sliding pipe 2 16 slide toward the direction close to the suction pipe 4, since the bellows 17 are separated by the connecting pipe 18 instead of a whole bellows 17, the bellows 17 are not easy to bend during the compression process, thereby avoiding the bellows 17 from bending during the compression process, which causes the suction pump 5 to have poor suction.

[0026] like Figure 2 and Figure 6As shown, the inner wall of the through groove 2 is fixedly connected with a plurality of evenly arranged push rods 20, and the push rods 20 are located between the paired slide rods 9; the end of the push rod 20 away from the inner wall of the through groove 2 is fixedly connected with a spring 1 21; the end of the push rod 20 close to the spring 1 21 is slidably connected with a sleeve 22; the spring 1 21 is fixedly connected to the inner wall of the sleeve 22, and the end of the sleeve 22 away from the push rod 20 is closed; the end of the sleeve 22 away from the push rod 20 is rotatably connected with a roller 23; during operation, when the slide tube 14 and the slide tube 2 16 slide, the surface of the roller 23 passes through the surfaces of the slide tube 14, the slide tube 2 16 and the fixed tube 13, although the diameters of the three are the same. Different, but the spring 1 21 will push the sleeve 22 through its own elastic force, so that the roller 23 at the end of the sleeve 22 can be pressed tightly against their surface. Since there are multiple push rods 20, springs 1 21, sleeves 22 and rollers 23, the slide tube 14, the slide tube 2 16 and the fixed tube 13 can always be subjected to pressure from all sides, thereby ensuring that the slide tube 14, the slide tube 2 16 and the fixed tube 13 can always be on the central axis of the through groove 2, thereby reducing the swing amplitude of the slide tube 14, the slide tube 2 16 and the fixed tube 13, avoiding their excessive swing and metal fatigue, which will cause the fixed tube 13 to fall off from the support frame 3.

[0027] like Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown, a pair of symmetrically arranged arc-shaped plates 24 are installed inside the support frame 3; a plurality of evenly arranged placement grooves 25 are opened on the surface of the arc-shaped plates 24, and the placement grooves 25 pass through the arc-shaped plates 24; a receiving frame 26 is fixedly connected to the bottom surface of the arc-shaped plates 24 at the corresponding positions of the placement grooves 25; a slip ring 27 is installed on the top surface of the support frame 3; the stator of the slip ring 27 is fixedly connected to the top surface of the support frame 3, and the stator of the slip ring 27 is connected to the suction pipe 4; the rotor of the slip ring 27 is fixedly connected to the guide pipe 28, and the rotor is driven by a servo motor, and the servo motor The machine is connected to the battery; when working, in order to improve the accuracy of water samples and reduce accidental errors, multiple sampling is often required. At this time, the servo motor will drive the rotor outside the slip ring 27 to rotate, so that the guide tube 28 can be aligned with the collection tank 6 on the surface of the rotating arc plate 24, and after filling a collection tank 6, the servo motor drives the guide tube 28 to rotate to the next unfilled collection tank 6, thereby achieving the purpose of multiple sampling, and then the user only needs to take out the filled collection tank 6 from the placement slot 25 and the receiving frame 26 to obtain the water sample.

[0028] like Figure 7 and Figure 9As shown, a pair of symmetrically arranged baffles 29 are fixedly connected to the surface of the collection tank 6 near the top; an annular plate 30 is fixedly connected to the top surface of the arc plate 24 at the corresponding position of the placement groove 25; an annular groove 31 is opened on the inner side of the annular plate 30; a pair of symmetrically arranged notches 32 are opened on the top surface of the annular plate 30, and the notches 32 are adapted to the baffles 29; when working, when the user puts the collection tank 6 into the collection tank, the user needs to align the baffles 29 on the surface of the collection tank 6 with the surface of the annular plate 30. The notch 32 is formed, and then the collection tank 6 is placed in the placement groove 25. At this time, the baffle 29 on the surface of the collection tank 6 will pass through the notch 32 and enter the annular groove 31, and the bottom of the collection tank 6 will be supported by the receiving frame 26. Then the user rotates the collection tank 6 so that the baffle 29 on the surface of the collection tank 6 is no longer aligned with the notch 32. At this time, the annular groove 31 can limit the top of the collection tank 6, thereby cooperating with the receiving frame 26 to fix the collection tank 6, thereby preventing the collection tank 6 from falling out of the placement groove 25 due to wind and waves.

[0029] like Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, a pair of electric push rods 33 are fixedly connected to the bottom of the arc plate 24 inside the support frame 3, and the telescopic ends of the electric push rods 33 are fixedly connected to the bottom surface of the arc plate 24; the top surface of the collecting tank 6 is threadedly connected to a top cover 34; a water injection hole 35 is opened at the middle position of the top surface of the top cover 34; a straight pipe 351 is fixedly connected to the bottom surface of the top cover 34 at the water injection hole 35; a blocking plate 36 is provided on the bottom surface of the straight pipe 351; a spring 37 is fixedly connected between the blocking plate 36 and the top cover 34; the guide pipe 28 is L-shaped and made of hard material; a pair of water outlets 38 are opened at the end of the guide pipe 28 away from the slip ring 27; during operation, when the guide pipe 28 needs to pour water sample into the collecting tank 6, the electric push rod 33 is fixedly connected to the bottom surface of the collecting tank 6 The rod 33 is started, thereby pushing the curved plate 24 and the collection tank 6 up, so that the vertical part of the guide tube 28 is inserted into the water injection hole 35 on the surface of the top cover 34, and squeezes the plugging plate 36 at the bottom of the straight tube 351, so that the plugging plate 36 is away from the straight tube 351, and stretches the spring 2 37. The water sample sucked up then flows out through the water outlet 38 on the surface of the suction tube 4, and enters the collection tank 6 through the gap between the plugging plate 36 and the straight tube 351. When the water sample is collected, the electric push rod 33 drives the curved plate 24 to descend, and the guide tube 28 no longer squeezes the plugging plate 36. At this time, the spring 1 21 recovers, thereby driving the plugging plate 36 to re-engage with the bottom surface of the straight plate, thereby closing the water injection hole 35, thereby avoiding interference from external rainwater.

[0030] like Figures 9 and 10As shown, a sealing ring 39 is embedded on the side of the blocking plate 36 close to the straight tube 351; a docking groove 40 is provided on the side of the sealing ring 39 close to the straight tube 351; the docking groove 40 is arranged in the form of an annular groove 31; the width of the notch of the docking groove 40 is greater than the width of its bottom, and the width of the bottom of the docking groove 40 is less than the thickness of the straight tube 351; during operation, when the blocking plate 36 blocks the straight tube 351, the bottom of the straight tube 351 will be inserted into the docking groove 40 on the surface of the sealing ring 39, and since the width of the notch of the docking groove 40 is greater than the width of its bottom, and the width of the bottom of the docking groove 40 is less than the thickness of the straight tube 351, when the straight tube 351 is inserted into the bottom of the docking groove 40, the side wall of the docking groove 40 will clamp the straight tube 351 due to its own elasticity, thereby improving the sealing performance of the blocking plate 36 on the straight tube 351.

[0031] like Figures 1 to 3 As shown, the bottom surface of the support frame 3 is fixedly connected to a base 41, and the base 41 is arranged in a ring shape; the base 41 is slidably connected to the top surface of the buoy 1; a pair of stacked levers 42 are fixedly connected to the support surface near the top position; during operation, when the user drives the boat close to the embodiment of the present invention, the user can rotate the support frame 3 and the base 41 through the lever 42, so that the collection tank 6 on the support frame 3 is facing himself, thereby making it convenient for the user to collect the collection tank 6.

[0032] During operation, in order to facilitate long-term monitoring of designated waters, an embodiment of the present invention can be used. First, the deployment of the embodiment of the present invention requires the user to move multiple embodiments of the present invention to the designated waters by boat, and then the user places the embodiments of the present invention in different areas of the designated waters. At this time, the buoy 1 will float on the water surface under the action of its own buoyancy, and the counterweight block 801 will sink to the bottom of the water due to gravity. At this time, the chain 8 between the counterweight block 801 and the buoy 1 can limit the position of the buoy 1 so that it is always on the top surface of the counterweight block 801, thereby enabling the embodiment of the present invention to be fixed in the designated waters for a long time. Afterwards, whenever the user needs to go to the designated waters to obtain water samples, the user can start the suction pump 5 in advance by remote control to allow the suction pipe 4 to draw water samples through the bottom of the tank 2. Then, the sucked water samples pass through the suction pump 5 and are discharged from the discharge pipe 401 and enter the collection tank 6. Therefore, when the user arrives, he only needs to replace the collection tank 6 to complete the water sampling operation, and the user no longer needs to perform a collection operation every time he arrives at an area, thereby improving the efficiency of water sample collection.

[0033] When the water level in the water area where the embodiment of the present invention is located rises due to precipitation or other factors, the slide rod 9 on the inner wall of the through groove 2 will slide relative to the buoy 1, so that the slide rod 9 and the connecting ring 10 can move below the water surface, so that the buoy 1 can continue to float up and adapt to the rising water surface, thereby avoiding the embodiment of the present invention being submerged by the water surface due to the rising water level and the unchanged length of the chain 8.

[0034] In order to facilitate the user to collect water samples at different depths, the user can remotely control or set the collection program in advance, so that the servo motor drives the driving tube 11 to rotate, and the rotating driving tube 11 will drive the sleeve 12 to rotate. Since the sleeve 12 is threadedly connected to the fixed tube 13, the sleeve 12 drives the sliding tube 14 connected to its rotation to move in the direction away from the suction pump 5. Since the sleeve 12 is threadedly connected to the top tube 15, and the top tube 15 is fixedly connected to the sliding tube 2 16, the top tube 15 will also move in the direction away from the suction pump 5, thereby achieving relative sliding between the sliding tube 14, the sliding tube 2 16 and the fixed tube 13, thereby achieving the effect of driving the bottom of the telescopic tube to penetrate into different depths underwater, thereby facilitating the user's operation of sampling water bodies at different depths, so that the user can have a more comprehensive understanding of the water quality of the specified water area.

[0035] When the slide pipe 14 and the slide pipe 2 16 slide in the direction away from the suction pipe 4, the slide pipe 14 will pull the connecting pipe 18 at the bottom, and then the connecting pipe 18 will pull the bellows 17, so that the bellows 17 can be stretched. At the same time, the connecting pipes 18 between each bellows 17 will also slide inside the top pipe 15 and the driving pipe 11 through the slide plate 19. When the tube 1 and the slide pipe 2 16 slide in the direction close to the suction pipe 4, since the bellows 17 are separated by the connecting pipe 18 instead of being a complete bellows 17, the bellows 17 is not easy to bend during the compression process, thereby avoiding the bellows 17 from bending during the compression process, which causes the suction pump 5 to have poor suction.

[0036] When the slide tube 14 and the slide tube 2 16 slide, the surface of the roller 23 passes through the surfaces of the slide tube 14, the slide tube 2 16 and the fixed tube 13. Although the diameters of the three are different, the spring 1 21 will push the sleeve 22 through its own elastic force, so that the roller 23 at the end of the sleeve 22 can be pressed tightly against their surfaces. Since there are multiple push rods 20, springs 1 21, sleeves 22 and rollers 23, the slide tube 14, the slide tube 2 16 and the fixed tube 13 can always be subjected to pressure from all sides, thereby ensuring that the slide tube 14, the slide tube 2 16 and the fixed tube 13 can always be on the central axis of the through groove 2, thereby reducing the swing amplitude of the slide tube 14, the slide tube 2 16 and the fixed tube 13, avoiding excessive swinging and metal fatigue, which in turn causes the fixed tube 13 to fall off the support frame 3.

[0037] In order to improve the accuracy of water samples and reduce accidental errors, multiple sampling is often required. At this time, the servo motor will drive the rotor on the outside of the slip ring 27 to rotate, so that the guide tube 28 can be aligned with the collection tank 6 on the surface of the rotating arc plate 24. After filling a collection tank 6, the servo motor drives the guide tube 28 to rotate to the next unfilled collection tank 6, thereby achieving the purpose of multiple sampling. Then the user only needs to take out the filled collection tank 6 from the placement slot 25 and the receiving frame 26 to obtain the water sample.

[0038] When the user places the collection tank 6 into the collection trough, the user needs to align the baffle 29 on the surface of the collection tank 6 with the notch 32 on the surface of the annular plate 30, and then place the collection tank 6 into the placement groove 25. At this time, the baffle 29 on the surface of the collection tank 6 will pass through the notch 32 and enter the annular groove 31, and the bottom of the collection tank 6 will be supported by the receiving frame 26. Then the user rotates the collection tank 6 so that the baffle 29 on the surface of the collection tank 6 is no longer aligned with the notch 32. At this time, the annular groove 31 can limit the top of the collection tank 6, thereby cooperating with the receiving frame 26 to fix the collection tank 6, thereby preventing the collection tank 6 from falling out of the placement groove 25 due to wind and waves.

[0039] When the guide tube 28 needs to pour water sample into the collection tank 6, the electric push rod 33 is started, thereby pushing the arc plate 24 and the collection tank 6 up, so that the vertical part of the guide tube 28 is inserted into the water injection hole 35 on the surface of the top cover 34, and squeezes the blocking plate 36 at the bottom of the straight tube 351, so that the blocking plate 36 is away from the straight tube 351, and stretches the spring 2 37, and then the sucked up water sample flows out through the water outlet 38 on the surface of the suction tube 4, and enters the collection tank 6 through the gap between the blocking plate 36 and the straight tube 351. When the water sample is collected, the electric push rod 33 drives the arc plate 24 to descend, and the guide tube 28 no longer squeezes the blocking plate 36. At this time, the spring 1 21 recovers, thereby driving the blocking plate 36 to re-engage with the bottom surface of the straight plate, thereby closing the water injection hole 35, thereby avoiding interference from external rainwater.

[0040] When the blocking plate 36 blocks the straight tube 351, the bottom of the straight tube 351 will be inserted into the docking groove 40 on the surface of the sealing ring 39. Since the width of the docking groove 40 is greater than the width of its bottom, and the width of the bottom of the docking groove 40 is less than the thickness of the straight tube 351, when the straight tube 351 is inserted into the bottom of the docking groove 40, the side wall of the docking groove 40 will clamp the straight tube 351 due to its own elasticity, thereby improving the sealing performance of the blocking plate 36 on the straight tube 351.

[0041] When the user drives the boat close to the embodiment of the present invention, the user can rotate the support frame 3 and the base 41 through the lever 42 so that the collection tank 6 on the support frame 3 faces the user, thereby facilitating the user to collect the collection tank 6.
