The positioning hoop 501 and the air bag 502 are matched to each other to make the mounting shell 1 float stably on the water surface, so that the staff can collect water samples.

[0032] Please refer to Figure 2 and Figure 3 A lifting mechanism 2 is arranged inside the mounting shell 1, and the lifting mechanism 2 includes a screw rod 201 rotatably connected to the inner top wall of the mounting shell 1, a slider 202 is threadedly connected to the surface of the screw rod 201, and the front and rear side surfaces of the slider 202 are respectively fixedly connected to two connecting rods 301, and the left and right side surfaces of the slider 202 are both fixedly connected to the limiting plates 203, and the left and right inner walls of the mounting shell 1 are fixedly connected to two limiting rods 204 that are slidably connected to one end away from the two limiting plates 203.

[0033] The rotation of the screw rod 201 will drive the slider 202 limited by the limit plate 203 and the limit rod 204 to move up and down, and at the same time, the two limit plates 203 will slide up and down on the limit rod 204.

[0034] Please refer to Figure 2 and Figure 3 The lifting mechanism 2 also includes a bottom plate 205 fixedly connected to the left and right inner walls of the mounting shell 1. The lower end of the screw rod 201 is connected to the bottom plate 205 through a bearing. The upper end of the screw rod 201 penetrates the mounting shell 1 and extends to the top of the mounting shell 1. The end of the screw rod 201 extending to the top of the mounting shell 1 is fixedly connected to a cross rod 206.

[0035] Preferably, a bottom plate 205 is provided to limit the lower end of the screw rod 201, which can prevent the screw rod 201 from shaking during rotation, so that the screw rod 201 can rotate more stably. A cross rotating rod 206 is provided to provide a reasonable force point for rotating the screw rod 201, which is more convenient to use.

[0036] Please refer to Figure 2 and Figure 3 A sampling mechanism 3 is provided on the lifting mechanism 2, and the sampling mechanism 3 includes a connecting rod 301 fixedly connected to the lifting mechanism 2, and a sampling tube 302 is fixedly connected to the lower end of the connecting rod 301. The front and rear sides of the sampling tube 302 are provided with sliding grooves 303, and slide plates 304 are slidably connected in the two sliding grooves 303.

[0037] Two compression springs 305 are fixedly connected to the upper ends of the two slides 304, and pressure plates 306 are fixedly connected to the side faces of the two slides 304 that are away from each other. A water outlet valve 307 is fixedly installed at the bottom of the sampling tube 302, and the collected water samples can be easily taken out through the water outlet valve 307 for the staff to conduct testing.

[0038] The connecting rod 301 and the sampling tube 302 can be raised and lowered under the drive of the slider 202. When the sampling tube 302 drives the pressure plate 306 to move to the top plate 405, the screw rod 201 is then rotated to make the pressure plate 306 drive the slide plate 304 to squeeze the compression spring 305 in the slide groove 303 under the limit of the top plate 405, so that the compression spring 305 is deformed. At this time, water can flow into the interior of the sampling tube 302 through the slide groove 303.

[0039] Please refer to Figure 4 Two limiting mechanisms 4 for limiting the pressure plate 306 are also provided inside the mounting shell 1. The limiting mechanism 4 includes a fixing cylinder 401 fixedly connected to the inner top wall of the mounting shell 1, an adjusting rod 402 is slidably connected to the inner wall of the fixing cylinder 401, a threaded block 403 is fixedly embedded at the lower end of the fixing cylinder 401, a threaded rod 404 is threadedly connected in the reserved threaded hole of the threaded block 403, and a top plate 405 is fixedly connected to the lower end of the adjusting rod 402.

[0040] The position of the adjusting rod 402 in the fixed tube 401 can be adjusted by loosening and tightening the threaded rod 404, and the depth of the top plate 405 in the water can be adjusted. The staff can adjust the depth of the water sample collection by adjusting the adjusting rod 402 to meet different detection requirements.

[0041] When the utility model is in use, the device is first placed on the water surface, and then the depth of the adjusting rod 402 in the water is adjusted by the threaded block 403 and the threaded rod 404. After the adjustment, the screw rod 201 is rotated by the cross rotating rod 206. The rotation of the screw rod 201 will drive the slider 202 limited by the limit plate 203 and the limit rod 204 to rise and fall. At the same time, the two limit plates 203 will slide up and down on the limit rod 204, and the connecting rod 301 and the sampling tube 302 can be lifted and lowered under the drive of the slider 202. When the sampling tube 302 drives the pressure plate 306 to move to the top plate 405, continuing to rotate the screw rod 201 will make the pressure plate 306 drive the slide plate 304 to squeeze the compression spring 305 in the slide groove 303 under the limit of the top plate 405, so that the compression spring 305 is deformed. At this time, the water flow can enter the interior of the sampling tube 302 through the slide groove 303, and the accurate collection of water samples at a certain depth is completed.
