[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1 — Figure 8 As shown, a water quality monitoring and analysis sampling device comprises a mounting shell 101, a connecting rod 102 is connected to the side of the mounting shell 101 by bolts, an end of the connecting rod 102 away from the mounting shell 101 is connected to a vertical rod 103 by bolts, a sampling mechanism is movably arranged in the mounting shell 101, and the sampling mechanism comprises a plurality of movable shells 201, each movable shell 201 is nested layer by layer, and the side walls of each movable shell 201 are sealed to prevent water from flowing between the side walls of the movable shells 201, the outermost movable shell 201 is slidably arranged in the mounting shell 101, and a filter screen 202 is arranged on the side of the movable shell 201, and the arrangement of the filter screen 202 prevents debris in the water from entering the storage tank. Water cylinder 204, to avoid affecting water quality analysis, a mounting groove 203 is provided in the movable shell 201, the mounting groove 203 is located at the position of the filter screen 202, a water intake assembly is provided in the mounting groove 203, the water intake assembly includes a water storage cylinder 204, the water storage cylinder 204 is detachably arranged in the mounting groove 203, before use, the staff needs to insert the clean water storage cylinder 204 into the mounting groove 203, and insert the sealing cover 207 into the mounting groove 203, every time a movable shell 201 is lowered into the water body, the filter screen 202 on the side of the movable shell 201 is exposed to the water body, the water at this depth passes through the filter screen 202 and enters the mounting groove 203, and finally flows into the water storage cylinder 204;

[0031] A limiting mechanism is provided on the movable shell 201, which is used to guide the movement of the installation shell 101 and each movable shell 201. An operating mechanism is provided on the connecting rod 102, which is used to press down the movable shells 201 one by one, so that the water storage cylinder 204 can take samples in layers in the water body.

[0032] In this embodiment, the water intake assembly includes a bottom plate 205, which is used to lift the water storage cylinder 204 installed in the installation groove 203. The bottom plate 205 is connected to a pull rod 206 by bolts, and the bottom plate 205 and the pull rod 206 are slidably connected in the installation shell 101. After the sampling is completed and the device is extracted from the water body, the staff lifts the pull rod 206 upward, and the pull rod 206 moves upward with the bottom plate 205. The bottom plate 205 lifts the water storage cylinder 204 and takes the water storage cylinder 204 and the sealing cover 207 out of the installation groove 203. The sealing cover 207 is detachably connected to the installation groove 203, and the sealing cover 207 is divided into two sections with different diameters. The section with a larger diameter of the sealing cover 207 is used to seal the installation groove 203, and the end with a smaller diameter of the sealing cover 207 is used to seal the water storage cylinder 204. The arrangement of the upper and lower sections facilitates the sealing of the water storage cylinder 204 and the installation groove 203, thereby reducing the number of operating steps.

[0033] In this embodiment, the limiting mechanism includes a limiting block 301, which is connected to the top of the movable shell 201 by bolts. A limiting groove 302 is provided on the inner side of the mounting shell 101 and the movable shell 201. The limiting block 301 is slidably arranged in the limiting groove 302. The setting of the limiting groove 302 limits the movement of the movable shell 201, so that the downward movement of the movable shell 201 is smoother, thereby avoiding water disturbance, destroying the stratification, and affecting the detection results.

[0034] In this embodiment, an elastic ball 303 is bonded to one end of the limit block 301, and a groove 304 matching the elastic ball 303 is opened on the inner side of the limit groove 302. The arrangement of the groove 304 and the elastic ball 303 enables each movable shell 201 to move to the lowest position, and the elastic ball 303 is stuck in the groove 304, which plays a locking role and prevents it from rising due to buoyancy.

[0035] In this embodiment, the operating mechanism includes a rotating seat 401, which is rotatably connected to the top of the movable shell 201. A telescopic rod 402 is connected to the rotating seat 401 by bolts. The end of the telescopic rod 402 away from the rotating seat 401 is connected to a mounting sleeve 403 by bolts. An operating rod 404 is slidably connected in the mounting sleeve 403. When taking water, the mounting shell 101 and each movable shell 201 are placed on the surface of the sampled water body, and the operating rod 404 presses down the movable shell 201 one by one from the outside to the inside. Each time a movable shell 201 is pressed down, the water at the position of the movable shell 201 is discharged, and the water of this layer flows into the water storage cylinder 204, that is, one layer of sampling is completed. In this way, the sampling depth is gradually increased, stratified sampling is realized, and the destruction of the water body stratification is effectively avoided during sampling.

[0036] In this embodiment, the bottom of the operating rod 404 is connected to a rotating hook 405 by bolts, and the top of the innermost movable shell 201 is connected to a cross bar 406 by bolts. Through the setting of the rotating hook 405 and the cross bar 406, after the sampling is completed, the rotating hook 405 hooks the cross bar 406 and lifts the movable shells 201 one by one until all the movable shells 201 enter the inner side of the installation shell 101 to complete the sampling operation.

[0037] In this embodiment, the installation shell 101 and the bottom of the movable shell 201 are connected by bolts with a scraper 104, and the scraper 104 is located at the corresponding position of the filter 202. During the upward movement of each movable shell 201, the filter 202 moves upward with the movable shell 201, and the scraper 104 scrapes the outer surface of the filter 202, which is easy to use.

[0038] Working principle: When the device is used, the device is moved to the water quality detection sampling position. In the initial state, each movable shell 201 is located inside the installation shell 101, forming a column together. The clean water storage cylinders 204 are inserted into the installation grooves 203 one by one, and the sealing cover 207 is inserted into the installation grooves 203. Then the vertical rod 103 is inserted into the water body so that the installation shell 101 is located on the surface of the water body. The staff uses the operating rod 404 to press down the movable shells 201 one by one from the outside to the inside. Each time a movable shell 201 is pressed down, the movable shell 201 is pressed down. The shell 201 slides relative to the adjacent upper movable shell 201, and the elastic ball 303 arranged on the limiting block 301 corresponding to the lower movable shell 201 slides in the limiting groove 302 opened on the inner side of the upper movable shell 201. During this process, the staff presses down the movable shell 201 to overcome the friction between the elastic ball 303 and the limiting groove 302, and the water at the position of the lower movable shell 201 is discharged, and the water in this layer flows into the water storage cylinder 204. When each movable shell 201 moves to the lowest position, the elastic ball 303 is stuck in the groove 3 04, which plays a locking role to prevent it from rising due to buoyancy, that is, a layer of sampling is completed. In this way, each movable shell 201 is pressed down. When the operating rod 404 presses the innermost movable shell 201 to the lowest position, the layered sampling is completed. Each movable shell 201 is in the order from the outside to the inside, and the corresponding water storage cylinder 204 takes water samples from shallow to deep. After the sampling is completed, the rotating hook 405 hooks the cross bar 406 to lift the movable shells 201 one by one. The elastic ball 303 corresponding to each movable shell 201 is subjected to an upward force. The elastic ball 303 is squeezed and disengaged from the inner groove 304 in which it is stuck. After the lock is released, the elastic ball 303 moves relatively in the limit groove 302 until all the movable shells 201 enter the inner side of the installation shell 101, completing the sampling operation, and then pulling out the vertical rod 103, moving the device to the sample temporary storage position, and lifting the pull rod 206 upward. The pull rod 206 moves upward with the bottom plate 205, and the bottom plate 205 lifts the water storage cylinder 204, and the water storage cylinder 204 and the sealing cover 207 are taken out of the installation groove 203, and the water storage cylinder 204 and the sample are properly stored.
