[0002] In the field of environmental monitoring, water quality monitoring is an important part. Water quality monitoring requires taking out water samples and then placing them into water sample analysis instruments for analysis. Therefore, water quality monitoring must use a water quality sampler. There are various types of water quality samplers.

[0024] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,in, Figure 1A schematic structural diagram of a preferred embodiment of a water quality sampler for environmental monitoring provided by the utility model; Figure 2 for Figure 1 A front view of a water quality sampler for environmental monitoring is shown; Figure 3 for Figure 1 A front view of a water quality sampler for environmental monitoring after the stretching rod is stored; Figure 4 for Figure 1 A front view of a limit sleeve in a water quality sampler for environmental monitoring is shown. A water quality sampler for environmental monitoring includes a water tank 1, a piston 2 movably sleeved inside the water tank 1, a stretching rod 3 fixedly sleeved on the top of the piston 2, a spring 4 fixedly connected to the top of the piston 2, a first pull rope 5 fixedly connected to the top of the stretching rod 3, a slot 6 provided on the side of the stretching rod 3, a limit sleeve 7 fixedly connected to the top of the water tank 1, a clamping plate 8 movably sleeved inside the limit sleeve 7, a second pull rope 9 fixedly connected to the side of the clamping plate 8, a floating ball 10 fixedly connected to one end of the second pull rope 9, a guide ring 11 fixedly connected to the top of the water tank 1, a sliding ball 12 movably sleeved on the top of the clamping plate 8, a limit rod 13 movably sleeved inside the piston 2, a sealing ring 14 fixedly sleeved on the outside of the piston 2, a counterweight 15 threadedly sleeved on the bottom of the water tank 1, and an auxiliary mechanism 16 provided on the side of the water tank 1.

[0026] The card plate 8 and the stretching rod 3 are perpendicular to each other, and the card plate 8 is adapted to the card slot 6; by setting the card plate 8, when water quality sampling is carried out, the stretching rod 3 is pressed so that the stretching rod 3 can drive the piston 2 to move downward, and the card plate 8 is slid at this time so that the card plate 8 can be moved to the inside of the card slot 6. At this time, the water tank 1 is placed into the sampling water area, so that when the water tank 1 sinks, the floating ball 10 can stretch the card plate 8 through the No. 2 pull rope 9, and then the card plate 8 can be moved out from the inside of the card slot 6, so that the spring 4 can drive the piston 2 to move, so that the water flow can be absorbed into the inside of the water tank 1, thereby achieving the effect of controlling the sampling depth by setting the length of the No. 2 pull rope 9, thereby improving the accuracy of the sampling depth.

[0027] One end of the spring 4 is fixedly connected to the top of the inner cavity of the water tank 1, and there are two springs 4. By setting the spring 4, when water quality sampling is performed, the spring 4 can drive the piston 2 to move up and down, so that the air inside the water tank 1 can be quickly squeezed out of the water tank 1, thereby achieving the water flow absorption effect, thereby achieving the automatic sampling effect of water quality.

[0028] The guide ring 11 is movably sleeved on the outside of the No. 2 pull rope 9, and the front shape of the guide ring 11 is an inverted U shape; by setting the guide ring 11, when water quality sampling is carried out, the guide ring 11 can guide the stretched No. 2 pull rope 9, so that the No. 2 pull rope 9 can drive the clamping plate 8 to move horizontally, thereby improving the smoothness of the No. 2 pull rope 9 when stretched.

[0029] There are several sliding balls 12, and the sliding balls 12 are evenly distributed on the top of the card plate 8. By setting the sliding balls 12, when the No. 2 pull rope 9 drives the card plate 8 to move horizontally, the sliding balls 12 can limit the horizontally moving card plate 8, thereby avoiding the problem of friction between the card plate 8 and the limit sleeve 7 when moving horizontally, thereby improving the smoothness of the horizontal movement of the card plate 8.

[0030] There are two limit rods 13, and the two limit rods 13 are symmetrically distributed with the stretching rod 3 as the symmetry axis; by setting the limit rods 13, when the piston 2 moves up and down to absorb water flow, the limit rods 13 can limit the piston 2 moving up and down, thereby avoiding the problem of tilting and offsetting when the piston 2 moves up and down, thereby improving the stability of the piston 2 when moving up and down.

[0031] The sealing ring 14 is adapted to the water tank 1, and the material of the sealing ring 14 is rubber material; by setting the sealing ring 14, when water flow absorption sampling is performed, the sealing ring 14 can greatly improve the sealing between the piston 2 and the inner wall of the water tank 1, thereby avoiding the problem that the water flow penetrates to the top of the piston 2 and is difficult to discharge when the piston 2 moves up and down, thereby improving the stability of water flow sampling and discharge.

[0032] The front shape of the counterweight block 15 is conical, and the material of the counterweight block 15 is stainless steel; by setting the counterweight block 15, when water quality sampling is carried out, the counterweight block 15 can greatly increase the weight of the water tank 1, thereby avoiding the problem that the buoyancy is large when there is more air inside the water tank 1, causing the water tank 1 to sink more slowly, thereby increasing the sinking speed of the water tank 1, that is, increasing the water quality sampling speed.

[0033] The auxiliary mechanism 16 includes a water pipe 161, which is fixedly sleeved on the side of the water tank 1, and a filter cover 162 is fixedly sleeved on one end of the water pipe 161; by setting the auxiliary mechanism 16, when water quality sampling is performed, the filter cover 162 is able to filter the water flow entering the water pipe 161, thereby preventing debris inside the water flow from entering the water pipe 161 along with the water flow, causing the water pipe 161 to be blocked, that is, avoiding the problem of blockage of the water quality sampler.

[0034] The working principle of the water quality sampler for environmental monitoring provided by the utility model is as follows:

[0035] Step 1: First, when sampling water quality, press the stretching rod 3 so that the stretching rod 3 can drive the piston 2 to move downward. At this time, slide the card plate 8 so that the card plate 8 can move to the inside of the card slot 6. At this time, put the water tank 1 into the sampling water area, so that when the water tank 1 sinks, the floating ball 10 can stretch the card plate 8 through the No. 2 pull rope 9, so that the card plate 8 can be moved out from the inside of the card slot 6, so that the spring 4 can drive the piston 2 to move, so that the water flow can be absorbed into the water tank 1, thereby achieving the effect of controlling the sampling depth by setting the length of the No. 2 pull rope 9, thereby improving the accuracy of the sampling depth. When sampling water quality, the spring 4 can drive the piston 2 to move up and down, so that the air inside the water tank 1 can be quickly squeezed out of the water tank 1, thereby achieving The water flow absorption effect is achieved, thereby achieving the automatic sampling effect of water quality. When water quality sampling is performed, the guide ring 11 is able to guide the stretched No. 2 pull rope 9, so that the No. 2 pull rope 9 can drive the card plate 8 to move horizontally, thereby improving the smoothness of the No. 2 pull rope 9 when stretched. When the No. 2 pull rope 9 drives the card plate 8 to move horizontally, the sliding ball 12 is able to limit the horizontally moving card plate 8, thereby avoiding the problem of friction between the card plate 8 and the limiting sleeve 7 when the card plate 8 moves horizontally, thereby improving the smoothness of the horizontal movement of the card plate 8. When the piston 2 moves up and down to absorb water flow, the limiting rod 13 is able to limit the piston 2 that moves up and down, thereby avoiding the problem of tilting and offsetting when the piston 2 moves up and down, thereby improving the stability of the piston 2 when it moves up and down;

[0036] Step 2: When water flow absorption sampling is performed, the sealing ring 14 can greatly improve the sealing between the piston 2 and the inner wall of the water tank 1, thereby avoiding the problem that the water flow penetrates to the top of the piston 2 and is difficult to discharge when the piston 2 moves up and down, thereby improving the stability of water flow sampling and discharge. When water quality sampling is performed, the counterweight block 15 can greatly increase the weight of the water tank 1, thereby avoiding the problem that the buoyancy is large when there is more air inside the water tank 1, causing the water tank 1 to sink more slowly, thereby increasing the sinking speed of the water tank 1, that is, improving the water quality sampling speed. When water quality sampling is performed, the filter cover 162 can filter the water flow entering the water pipe 161, thereby avoiding the problem that the debris inside the water flow enters the water pipe 161 along with the water flow, causing the water pipe 161 to be blocked, that is, avoiding the problem of blockage of the water quality sampler.

[0037] Compared with related technologies, the water quality sampler for environmental monitoring provided by the present invention has the following beneficial effects:

[0038] By setting the card plate 8, when water quality sampling is carried out, the stretching rod 3 is pressed so that the stretching rod 3 can drive the piston 2 to move downward. At this time, the card plate 8 is slid so that the card plate 8 can be moved to the inside of the card slot 6. At this time, the water tank 1 is placed into the sampling water area, so that when the water tank 1 sinks, the floating ball 10 can stretch the card plate 8 through the No. 2 pull rope 9, and then the card plate 8 can be moved out from the inside of the card slot 6, so that the spring 4 can drive the piston 2 to move, so that the water flow can be absorbed into the inside of the water tank 1, thereby achieving the effect of controlling the sampling depth by setting the length of the No. 2 pull rope 9, thereby improving the accuracy of the sampling depth.
