[0004] A Chinese patent discloses a water quality analysis sampling device with a publication number of CN220568453U, and the application date is 2023.07.07. The patented technology sets a circular plate, and under the action of a threaded rod, the threaded rod can drive the circular plate to slide on the inner wall of the sampling tube, so as to facilitate the adjustment of the position of the circular plate on the inner wall of the sampling tube according to actual needs, so that the volume of the sampling tube can be changed according to actual needs, effectively improving the practicality of the water quality sampler. However, although the above device can quantitatively take water, after the sampling tube takes water, the water source may enter the bottom of the circular plate from the notch at the connection between the circular plate and the threaded rod, making the original quantitative water source less. Therefore, the inventor provides a water quality sampling and analysis device to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] like Figure 1 , 4 As shown, a water quality sampling and analysis device includes a transparent container 10, a sampling structure 20 is arranged on the right side of the transparent container 10, the sampling structure 20 includes a support plate 201, a water pump 202 is fixedly connected to the top of the support plate 201, a sampling tube 203 is fixedly connected to the input end of the water pump 202, and a discharge pipe 204 is fixedly connected to the output end of the water pump 202, and the left side of the discharge pipe 204 is fixedly connected to the transparent container 10.

[0026] When in use, the sampling tube 203 is inserted into the water source to be analyzed, and the water pump 202 is started by an external power supply. The input end of the water pump 202 draws water through the sampling tube 203, and then discharges it into the interior of the transparent container 10 through the discharge pipe 204, thereby achieving the effect of water source sampling.

[0027] Preferably, Figure 4 As shown, a filter plate 205 is fixedly connected to the right side of the interior of the sampling tube 203. The filter plate 205 can prevent the mud and sand in the water source to be tested from entering the interior of the transparent container 10, making the transparent container 10 inconvenient to clean.

[0028] In daily work, it is found that when sampling water quality in different water bodies, the amount of water required for sampling is also different, but the volume of the water quality sampler is fixed. When sampling water quality, it is often difficult to control the amount of water sampled, resulting in a decrease in the overall practicality of the water quality sampler. Therefore, an adjustment structure 40 is proposed.

[0029] refer to Figure 2 , 3 The adjustment structure 40 includes a sealing plate 401, which is slidably connected to the inside of the transparent container 10. A pair of fixed frames 405 are fixedly connected to the front and rear sides of the bottom of the sealing plate 401. A rolling groove 406 is provided on the front side of the front of the fixed frame 405, and the fixed frame 405 is fixed to the left side of the middle of the bottom of the sealing plate 401, so that the rightmost inside of the rolling groove 406 corresponds to the middle position of the front of the sealing plate 401. The opposite sides of the two rolling grooves 406 are rollingly connected with driving rods 404, and the front and rear sides of the driving rod 404 are respectively fixedly connected with flippable connecting rods 403.

[0030] Preferably, the front and rear ends of the driving rod 404 are fixedly connected to limit covers 407 , and the height of the limit covers 407 is greater than the height of the rolling groove 406 , which can effectively prevent the driving rod 404 from escaping from the rolling groove 406 when in use.

[0031] Specifically, the front and rear sides of the transparent container 10 are rotatably connected to a rotating rod 402, the surface of the rotating rod 402 is fixedly connected to the two connecting rods 403, and the surface of the rotating rod 402 is fixedly connected to a gear 408; the inner bottom side of the transparent container 10 is fixedly connected to a fixed plate 411, the left side of the fixed plate 411 is fixedly connected to a cylinder 410, the output end of the cylinder 410 is fixedly connected to a toothed plate 409, and the toothed plate 409 is meshed with the gear 408.

[0032] When in use, the cylinder 410 is started by an external power supply, and the output end of the cylinder 410 extends to drive the tooth plate 409 to move leftward, thereby driving the rotating rod 402 to rotate clockwise through the transmission of the gear 408 and the tooth plate 409, thereby driving the connecting rod 403 to turn clockwise with the position of the rotating rod 402 as the center of the circle, so that the driving rod 404 turns upward and rolls inside the rolling groove 406, thereby driving the sealing plate 401 to move upward, so that the space above the transparent container 10 gradually becomes smaller. Similarly, when the output end of the cylinder 410 contracts, it will drive the sealing plate 401 to move downward, so that the space above the transparent container 10 gradually becomes larger.

[0033] Preferably, the left and right sides of the transparent container 10 are respectively fixedly connected with hollow tubes 412, the interior of the hollow tubes 412 is slidably connected with extension tubes 413, and the top of the extension tubes 413 is fixedly connected to the sealing plate 401. When the sealing plate 401 moves up and down, the extension tubes 413 are driven to slide along the interior of the hollow tubes 412, thereby achieving a guiding effect when the sealing plate 401 moves.

[0034] Preferably, the left side of the transparent container 10 is fixedly connected with a drain pipe 13, and a scale 12 is set on the left side of the front of the transparent container 10. The scale 12 increases downward from the horizontal position of the drain pipe 13 as a starting point. When in use, the height of the sealing plate 401 is adjusted according to the scale 12 according to different water sources. Then the sampling structure 20 is started, so that the water source input into the transparent container through the discharge pipe 204 will gather above the sealing plate 401 until the height of the water source exceeds the position of the drain pipe 13, and the excess water source will be discharged through the drain pipe 13, thereby achieving the effect of controlling the water intake of the water source. When the water source needs to be completely discharged, it is only necessary to raise the sealing plate 401 to a position level with the drain pipe 13, so that the water source inside the transparent container 10 will be discharged through the drain pipe 13.

[0035] refer to Figure 1 , 2 5. An analysis structure 30 is provided on the top of the transparent container 10, and the analysis structure 30 includes an analysis device body 301, and the analysis device body 301 is fixedly connected to the transparent container 10, and an analysis tube 302 is fixedly connected to the detection end of the analysis device body 301, and the analysis tube 302 passes through the top of the transparent container 10, and a fixed head 303 is fixedly connected to the bottom of the analysis tube 302, and the bottom of the fixed head 303 is fixedly connected to the sealing plate 401, and water inlet holes 304 are respectively opened on the left and right sides of the fixed head 303.

[0036] Preferably, the analysis tube 302 is designed to be foldable, and can be folded or stretched in coordination with the sealing plate 401 that moves up and down when in use, thereby preventing the analysis tube from being affected by the buoyancy of the water source or from being closed by the sealing plate 401 moving up and down.

[0037] When in use, the analysis device body 301 is started by an external power supply, and the analysis device body 301 extracts water from the transparent container 10 from the analysis tube 302 through the built-in pump body, and then analyzes the water source, thereby achieving the analysis effect of the water source.

[0038] The working principle of the utility model is as follows: the cylinder 410 is started by an external power supply, and the output end of the cylinder 410 is extended to drive the tooth plate 409 to move to the left, thereby driving the rotating rod 402 to rotate clockwise through the transmission of the gear 408 and the tooth plate 409, thereby driving the connecting rod 403 to turn clockwise with the position of the rotating rod 402 as the center of the circle, so that the driving rod 404 turns upward and rolls inside the rolling groove 406, thereby driving the sealing plate 401 to move upward, so that the space above the transparent container 10 gradually becomes smaller. Similarly, when the output end of the cylinder 410 contracts, it will drive the sealing plate 401 to move downward, so that the space above the container 10 gradually becomes larger, thereby achieving the effect of changing the internal capacity of the transparent container 10.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
