DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-11 A river water environment management and lifting device includes a fixed frame 1, a slide rail 13 is opened inside the top and bottom ends of the fixed frame 1, a sampling assembly for collecting sediment is provided inside the slide rail 13, and the sampling assembly includes a bottom support 2, the bottom support 2 is slidably connected to the slide rail 13, a support rod 21 is fixed on the top of the bottom support 2, a sampling cylinder 22 is fixed on the top of the support rod 21, connecting blocks 23 are fixed to the surfaces of both sides of the sampling cylinder 22, an extension tube 24 is fixed on the inner side of the connecting block 23, an extension tube 24 away from the bottom support 2 is threadedly connected to a tapered tube 25, and a filter screen 26 is fixed inside the tapered tube 25; The top of the sampling barrel 22 is fixed with a limit frame 3, the top of the limit frame 3 is fixed with a top support 31, the inside of the top support 31 is fixed with a first cylinder 32, the output shaft of the first cylinder 32 is fixed with a connecting plate 33, the bottom of both ends of the connecting plate 33 are fixed with movable doors 34, the movable doors 34 are clamped in the gap between the sampling barrel 22 and the extension tube 24, the top and bottom of the open end of the fixed frame 1 are fixed with a gear plate 11, the surface of the gear plate 11 is rotatably connected to the protective plate 12, a locking screw 14 is fixed to the surface of one of the gear plates 11, and the locking screw 14 is rotatably connected to the protective plate 12; The gap between the sampling tube 22 and the extension tube 24 is equal to the thickness of the movable door 34, and the two sides of the movable door 34 are respectively against the extension tube 24 and the sampling tube 22. A cross plate 251 is fixed inside the tapered tube 25, and a push rod 252 is fixed on the side of the cross plate 251 close to the filter screen 26, and the push rod 252 is against the filter screen 26. The connecting plate 33 is slidably connected to the limit frame 3. A water outlet 35 is opened on the surface of the movable door 34, and the aperture area of ​​the water outlet 35 is equal to the aperture area of ​​the sampling tube 22. A through hole 36 is opened in the middle of the surface of the movable door 34, and a nut 4 is threadedly connected to the surface of the support rod 21; In actual operation, when the present invention needs to perform multi-point sampling, the nut on the surface of the locking screw 14 is first rotated to release the lock of the gear plate 11 and the protective plate 12, and then the two fixing frames 1 are rotated. Under the action of the meshing of the two gear plates 11, the two fixing frames 1 are bent and deformed, and then the two fixing frames 1 respectively drive the sampling components in their respective slide rails 13 to move synchronously; Then, the nut 4 is rotated to release the lock of the nut 4 on the support rod 21 and the fixing frame 1. Then, according to the position to be sampled, the position of each sampling component is adjusted, and the sampling component is rotated so that the direction of the sampling component is consistent with the direction of the water flow. Then, the present invention is hoisted into the river channel by the lifting equipment, so that the two fixing frames 1 can carry the sampling components and completely sink into the river channel, so that the present invention can simultaneously perform multi-point sampling of the same layer of water body; The multi-point sampling horizontal sediment sampler in the prior art can only perform multi-point sampling in the same layer of water body with the width of the river channel as the reference level; Compared with the multi-point sampling horizontal sediment sampler in the prior art, the sampling device of the present invention not only realizes the basic functions of the horizontal sediment sampler, but also can select sampling points at different positions within the area with the protective plate 12 as the center and the fixed frame 1 as the radius according to sampling requirements. It is not limited to sampling based on the width of the river channel as the reference level. Instead, by adjusting the relative angle of the two fixed frames 1, the present invention can place sampling components at different gradients in the same layer of water, so that the scope of single multi-point sampling of the present invention is wider, ensuring a low repetition rate of samples, thereby improving the accuracy of sampling detection, and playing a key role in improving the management of the water environment of the river channel.

[0020] Specifically, after the sampling assembly is sunk into the river water, the first cylinder 32 is activated by the controller, so that the first cylinder 32 is pushed out and drives the connecting plate 33 and the movable door 34 to move downward along the vertical direction of the limiting frame 3, so that the movable door 34 moves downward in the gap between the sampling barrel 22 and the extension tube 24 until the water outlet 35 is aligned with the two ends of the sampling barrel 22. At this time, the extension tube 24, the water outlet 35 and the sampling barrel 22 are connected to each other, so that the two ends of the sampling barrel 22 are in the water body and are in an open and closed state; At this time, the sediment in the flowing water body is carried by the water flow and flows toward the interior of the sampling tube 22. In the process of the sediment flowing into the sampling tube 22, the filter 26 filters the debris and garbage in the water body, thereby reducing the probability of the debris and garbage entering the interior of the sampling tube 22, thereby improving the accuracy of the sampling of the present invention, and then making the subsequent detection data more accurate, so as to effectively improve the effect of water environment management; Furthermore, with the support of the top rod 252 on the filter 26, the filter 26 takes on a conical shape, which reduces the probability of debris being adsorbed on the surface of the filter 26. The debris is allowed to flow along the surface of the filter 26 and away from the filter 26 under the influence of the water flow. This improves the smoothness of the filtration of the filter 26, reduces the probability of sediment blockage, and further improves the accuracy of sampling. At the same time, in the conical state of the conical tube 25, the water flow entering the conical tube 25 is limited by the conical tube 25, and the water flow dispersed by the filter 26 and the turbulence and vortex in the water body are integrated. The flow of the water body after the confluence is more stable and the turbulence is reduced, thereby reducing the sedimentation of coarse particles in front of the filter screen and the probability of non-target water layer sediment being drawn in. The water flow and sediment filtered by the filter screen 26 can be concentrated and introduced into the sampling tube 22, reducing sample leakage and further improving the accuracy of water sediment sampling. After the sampling is completed, the controller controls the return of the first cylinder 32, and the first cylinder 32 drives the connecting plate 33 and the movable door 34 to return, so that the movable door 34 moves up in the vertical direction of the limit frame 3, and then the water outlet 35 and the openings at both ends of the sampling tube 22 are gradually misaligned until the two ends of the sampling tube 22 are closed by the movable door 34, so that the water body sediment is intercepted inside the sampling tube 22, and then the present invention is lifted out of the water by lifting equipment.

[0021] It should be noted that all devices of the present invention are controlled by a controller, wherein two fixing frames 1 are provided, and a gear plate 11 is provided on the top and bottom surfaces of each fixing frame 1. The gear plates 11 provided on the two fixing frames 1 are meshed with each other, so that the two fixing frames 1 can rotate around the protective plate 12 as the axis under the action of the gear plates 11; The sampling components are independent components, and the corresponding number can be selected according to actual needs. The sampling components are installed inside the slide rail 13 through the open end of the slide rail 13. The sampling components can be adjusted to a specified position inside the slide rail 13 and the angle can be adjusted to ensure that the orientation of each sampling component is consistent with the direction of the water flow, thereby reducing the impact of the water flow on the present invention, thereby improving the stability of the present invention during sampling, and ensuring that the present invention can take the water sediment in the specified target laminar flow; At the same time, the tapered tube 25 and the extension tube 24 are connected by threads. When the river water is clean, the tapered tube 25 can be installed.

[0022] Embodiment 2: A second cylinder 5 is fixed inside the support rod 21, and the output shaft of the second cylinder 5 is slidably and sealedly connected to the sampling tube 22. A support plate 51 is fixed on the top of the output shaft of the second cylinder 5. A guide groove 52 is opened inside the support plate 51. The two sides of the support plate 51 are rotatably connected to the shifting rod 53, and the two sides of the shifting rod 53 are fixed with blades 54; Specifically, based on the first embodiment, during the sampling process, or during the process of transporting the present invention after the sampling is completed, the controller starts the second cylinder 5 and controls the second cylinder 5 to repeatedly push out and return, so that the second cylinder 5 drives the support plate 51 and the lever 53 to repeatedly rise and fall inside the sampling tube 22, and the lever 53 drives the blade 54 to repeatedly rise and fall inside the sampling tube 22; Since the sampling tube 22 is in the river water body and is filled with water, when the lever 53 drives the blade 54 to rise and fall repeatedly, the blade 54 is turned over by the resistance of the water flow, which in turn drives the lever 53 to turn over. As the lever 53 moves up and down, it turns over, thereby winding up the filamentous debris in the sampling tube 22. When the subsequent sampling is completed and distributed, the probability of the filamentous debris entering the sampling bottle is reduced, and the subsequent cleaning steps of the sample are reduced. Furthermore, the lever 53 can stir the water flow in the sampling tube 22 during the repeated lifting and lowering process. When the sampling tube 22 is sampling, the lever 53 can further prevent the sediment of different particle sizes from settling, thereby improving the accuracy of sampling. After the sampling is completed in the later stage, when the sample in the sampling tube 22 is packaged, the sample can also be stirred by the lever 53, so that the sediment is dispersed more evenly in the water body, and the sediment content of the packaged sample is more uniform, thereby improving the accuracy of the later detection data.

[0023] It should be noted that the function of the guide groove 52 is to further accelerate the water flow passing through the guide groove 52, that is, the water flow rate inside the guide groove 52 is further accelerated, so that a flow rate difference is formed inside and outside the guide groove 52. Under the action of the flow rate difference, one side of the blade 54 is impacted by the fast water flow, while the other side is impacted by the slow water flow, thereby increasing the impact force of the water flow around the guide groove 52 on the blade 54, further improving the efficiency of the blade 54 flipping, and improving the efficiency of the lever 53 in entangling the filamentous debris.

[0024] Embodiment 3: A drain port 6 is provided inside the movable door 34 near the side of the limiting frame 3. A receiving groove 61 is provided inside the movable door 34 above the drain port 6. A sealing door 62 is slidably and sealedly connected inside the receiving groove 61. The sealing door 62 is slidably and sealedly connected to the drain port 6. A paddle 63 is fixed to the surface of the sealing door 62 away from the limiting frame 3. A spring 64 is fixed to the top of the sealing door 62. The spring 64 is located inside the receiving groove 61, and one end of the spring 64 is fixed to the inner wall of the receiving groove 61. A guide port 7 is provided on the surface of the fixing frame 1, which is connected to the slide rail 13. A guide vane 71 is rotatably connected to the inside of the guide port 7. A telescopic tube 8 is fixed to the inside of the closed end of the fixing frame 1. The telescopic tube 8 is composed of a plurality of pipes connected by threads, and a threaded column 81 is connected to the internal thread of the top of the innermost pipe. An extension plate 82 is fixed to the top of the threaded column 81. A slide groove 83 is provided inside the extension plate 82. A lead screw 84 is rotatably connected to the inside of the slide groove 83. A slider 85 is threadedly connected to the surface of the lead screw 84. The slider 85 is slidably connected to the slide groove 83. A rotating plate 86 is hinged at the bottom of the slider 85, and a hook 87 is fixed to the surface of the rotating plate 86. Specifically, based on the first embodiment, if the present invention needs to be transported to a designated location in the river for sampling by moving a ship, the threaded column 81 can be rotated first, so that the threaded column 81 drives the extension plate 82 to rotate, and the extension plate 82 is controlled to be directed toward the railing of the ship, and then the lead screw 84 is rotated so that the lead screw 84 drives the slider 85 and the rotating plate 86 to slide inside the slide groove 83, so that the rotating plate 86 moves to the maximum stroke, and then the telescopic tube 8 is rotated to make the telescopic tube 8 telescopically adjusted, so that the telescopic tube 8 drives the extension plate 82 to move up and down, so that the distance between the extension plate 82 and the fixing frame 1 is increased; When the lifting equipment lifts the present invention to the specified depth after the river water body, the extension plate 82 is clamped on the top of the ship's railing. At this time, the rotating plate 86 is flipped so that the rotating plate 86 and the slider 85 are in a vertical state. Then the screw 84 is reversed so that the screw 84 drives the slider 85 and the rotating plate 86 to move toward the railing of the ship until the rotating plate 86 contacts the railing. The hook 87 and the rotating plate 86 form a clamping limit for the railing, and then the present invention can be hung on the ship's railing. The ship and the present invention jointly bear the impact of the water flow, thereby improving the stability of the present invention during sampling, avoiding sampling deviation and reducing sampling accuracy. After the sampling is completed and the sample needs to be distributed, the paddle 63 can be moved so that the paddle 63 drives the sealing door 62 to slide inside the storage groove 61 and the drain outlet 6, so that the drain outlet 6 is opened, and then the sample in the sampling tube 22 is discharged to the outside through the drain outlet 6, and can be collected at this time.

[0025] It should be noted that, see Figure 8The rotating plate 86 is limited by the slider 85, and its maximum flipping angle is ninety degrees. When the present invention is sampling in the water body, the water flow contacts the guide vane 71 when impacting the fixed frame 1, and drives the guide vane 71 to flip, thereby opening the guide port 7, so that the water flow can be discharged to the outside through the guide port 7 when impacting the fixed frame 1. Compared with the traditional horizontal sediment multi-point sampler, the present invention can reduce the impact force of the water flow on the fixed frame 1, and further improve the sampling stability of the present invention; and the paddle 63 is affected by the elastic force of the spring 64 in the absence of external force, and the sealing door 62 is maintained in the ejected state, that is, the drain outlet 6 is always in a closed state, thereby ensuring the sealing performance of the movable door 34 to the sampling tube 22, and avoiding leakage during sample transportation.
