Description

Technical Field

[0001] This utility model relates to the technical field of water turbidity analyzers, specifically an absorption-type water turbidity analysis device. Background Technology

[0002] Several existing water turbidity analysis instruments often require manual sampling and placement into the turbidity analyzer. They cannot achieve the goal of drawing the test liquid into the analyzer by aspiration. Furthermore, existing methods of liquid aspiration are prone to difficulty in controlling the amount drawn, making quantitative detection inconvenient.

[0003] The invention patent with publication number CN111044454B discloses an absorption-type water turbidity analyzer, including a turbidity analyzer, an absorption box fixedly installed on the top of the turbidity analyzer, an absorption hose and an air bladder fixedly installed on the top of the absorption box, a connecting cylinder fixedly installed on the top of the absorption box, the air bladder being fixedly connected to the absorption box through the connecting cylinder, a rope tube fixedly installed on the top of the turbidity analyzer, two sets of No. 1 mounting seats fixedly installed on the top of the absorption box, a central shaft fixedly installed between the two sets of No. 1 mounting seats, a rocker arm movably installed on the outer wall of the central shaft, an inner cavity provided in the absorption box, a rotating shaft and a detection groove provided at the bottom of the inner cavity, an inclined plate fixedly installed on the outer wall of the rotating shaft, a rotating wheel sleeved on the bottom outer wall of the rotating shaft, and a sliding wheel fixedly installed on the side of the rotating wheel. This device can draw the test liquid into the device for detection in a closed environment, while simultaneously returning excess liquid to prevent waste of the test liquid.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the airbags are designed to be manually pressed to control the aspiration of the sample liquid. Since the volume of the airbags is small, the amount of liquid aspirated by pressing is small. Therefore, the sample liquid needs to be placed in front of the aspiration tube after sampling, and then the airbag needs to be pressed to effectively aspirate the liquid. In other words, the aspiration stroke of the above-mentioned existing technology is short and is not suitable for remote sampling on site.

[0005] Therefore, this utility model provides an absorption-type water turbidity analysis device. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a suction-type water turbidity analysis device to solve the problems mentioned in the background. This invention has the function of remote sampling and supplying sample liquid to the suction tube, and has the advantages of on-site remote sampling and testing, which greatly improves the analysis efficiency.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a suction-type water turbidity analysis device, including a turbidity analyzer, a base and a suction box located above the base are provided on the turbidity analyzer, a suction hose and a detection airbag are provided on the suction box, an annular sleeve located on one side of the suction hose is provided on the base, an eccentrically distributed rolling ring is provided inside the annular sleeve, and a sampling airbag is provided near the inner wall of the annular sleeve, one end of the sampling airbag is connected to a one-way suction hose and the other end is connected to a one-way discharge hose.

[0008] Furthermore, the bottom of the annular sleeve is fixedly connected to the base via a vertical plate, and a positioning plate located below the rolling ring is fixedly connected to one side of the vertical plate. The bottom of the positioning plate is provided with a rotating shaft coaxial with the annular sleeve, and the top of the rotating shaft is fixedly connected to an arm plate that is rotatably connected to the middle of the rolling ring.

[0009] Furthermore, a crank handle is fixedly connected to the top of the rotating shaft.

[0010] Furthermore, one end of the one-way pumping hose is connected to an inlet pipe, and a one-way valve is connected in series on the inlet pipe, with one end of the valve connected to the sampling airbag. One end of the one-way outlet hose is connected to an outlet pipe, and a one-way valve is connected in series on the outlet pipe, with one end of the outlet valve connected to the other end of the sampling airbag.

[0011] Furthermore, the positioning plate and the annular sleeve are fixedly connected with plate one and plate two, which are respectively fixedly connected to the water inlet pipe and the water outlet pipe.

[0012] Furthermore, an outer protective rubber ring is fixedly connected to the outer peripheral wall of the rolling ring, and an inner protective rubber ring is fixedly sleeved on the inner peripheral wall of the annular sleeve.

[0013] Furthermore, the outer peripheral wall of the annular sleeve is fixedly connected with circumferentially evenly distributed support rods near the bottom.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, an annular sleeve and a rolling ring located inside the annular sleeve are provided on the base. A sampling airbag is then provided on the inner side wall of the annular sleeve. By eccentrically setting the rolling ring, it can periodically roll the sampling airbag when it rolls. A one-way water outlet hose and a one-way water pumping hose are provided at both ends of the sampling airbag, which facilitates continuous outdoor remote sampling. Compared with the prior art, it has the function of remote sampling in place, which greatly improves the efficiency of water turbidity analysis.

[0016] In this invention, a ring of support rods is provided on the outer periphery of the annular sleeve. When not in use, the one-way water hose can be wrapped around the outer periphery of the annular sleeve and supported by the support rods, thus providing the advantage of convenient storage of the one-way water hose.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: an absorption-type water turbidity analysis device, including a turbidity analyzer 1, a base 11 and an absorption box 12 located above the base 11 on the turbidity analyzer 1, an absorption hose 13 and a detection airbag 14 on the absorption box 12. When it is necessary to analyze the sample liquid, one end of the absorption hose 13 is inserted into the sample liquid, and then the detection airbag 14 is manually pressed. The absorption box 12 draws the sample liquid under negative pressure. At this time, the turbidity analyzer 1 can perform quantitative analysis on the absorbed sample liquid. The working principle of the turbidity analyzer 1 adopts the structure in the patent documents mentioned in the background art, which will not be repeated in this application.

[0023] In this technical solution, an annular sleeve 2 is provided on the base 11, located on one side of the suction hose 13. During use, a dish can be installed on one side of the suction hose 13, and one end of the suction hose 13 is placed into the dish. An eccentrically distributed rolling ring 3 is provided inside the annular sleeve 2, and the rolling ring 3 is parallel to the annular sleeve 2. When the rolling ring 3 moves, it will revolve relative to the annular sleeve 2. A sampling airbag 4 is provided inside the annular sleeve 2 near the inner wall. When the rolling ring 3 moves, it will periodically roll the sampling airbag 4, so the sampling airbag 4 will periodically undergo cyclical changes of contraction and expansion. One end of the sampling airbag 4 is connected to a one-way suction hose 5, and the other end is connected to a one-way discharge hose 6. When the sampling airbag 4 contracts and expands, the one-way suction hose 5 will draw water, and the one-way discharge hose 6 will drain water. When the discharge end of the one-way discharge hose 6 is placed into the dish, water samples from a distance can be introduced into the dish, which facilitates short-range effective liquid aspiration by the suction hose 13.

[0024] Specifically, the bottom of the annular sleeve 2 is fixedly connected to the base 11 via the upright plate 21. A positioning plate 211 located below the rolling ring 3 is fixedly connected to one side of the upright plate 21. The bottom of the positioning plate 211 is provided with a rotating shaft 2111 coaxial with the annular sleeve 2. The top of the rotating shaft 2111 is fixedly connected to an arm plate 21111 that is rotatably connected to the middle of the rolling ring 3. Specifically, the positioning shaft is welded to the free end of the arm plate 21111. The inner circumferential wall of the rolling ring 3 is welded with a positioning sleeve that is rotatably connected to the positioning shaft via a connecting plate. Thus, when the rotating shaft 2111 rotates, it can drive the rolling ring 3 to revolve. When the rolling ring 3 passes the sampling airbag 4, the sampling airbag 4 will be rolled and contracted. When the rolling ring 3 moves away from the sampling airbag 4, the sampling airbag 4 will recover using its own elasticity.

[0025] Among them, the top of the rotating shaft 2111 is fixedly connected to the crank handle 7, which is a hand-held component for manually controlling the revolution of the rolling ring 3, making the revolution control of the rolling ring 3 more convenient.

[0026] In this embodiment, one end of the one-way pumping hose 5 is connected to an inlet pipe 51, and a one-way valve 511 is connected in series on the inlet pipe 51, with one end of the valve connected to the sampling airbag 4. One end of the one-way outlet hose 6 is connected to an outlet pipe 61, and a one-way valve 611 is connected in series on the outlet pipe 61, with one end of the outlet pipe connected to the other end of the sampling airbag 4. The positioning plate 211 and the annular sleeve 2 are fixedly connected to a plate 2112 and a plate 23, respectively, which are fixedly connected to the inlet pipe 51 and the outlet pipe 61. This arrangement allows for the positioning of the sampling airbag 4.

[0027] In this embodiment, an outer protective rubber ring 8 is fixedly connected to the outer peripheral wall of the rolling ring 3, and an inner protective rubber ring 9 is fixedly sleeved on the inner peripheral wall of the annular sleeve 2. This arrangement can protect the sampling airbag 4 and prevent it from being squeezed and damaged.

[0028] In this embodiment, the outer peripheral wall of the annular sleeve 2 is fixedly connected with support rods 22 that are evenly distributed around the circumference and close to the bottom. Since the one-way water pumping hose 5 used is relatively long, when this device is not in use, the hose part of the one-way water pumping hose 5 is wrapped around the outer periphery of the annular sleeve 2. At this time, the hose will be supported by the support rods 22, which has the advantage of convenient storage of the one-way water pumping hose 5.

[0029] Working principle: During on-site sampling, the operator places the turbidity analyzer 1 on the ground or on a boat, then throws one end of the one-way water suction hose 5 into the water, and then holds the crank handle 7 to rotate the rotating shaft 2111. At this time, the rolling ring 3 begins to revolve. When it passes the inflated sampling airbag 4, the sampling airbag 4 is pressed. When the rolling ring 3 leaves, the sampling airbag 4 returns to its original state. This cycle continues, and the sampling airbag 4 will discharge the sample liquid into the dish through the one-way water outlet hose 6. The operator can insert one end of the suction hose 13 into the sample liquid in the dish, and then manually press the detection airbag 14. At this time, the turbidity analyzer 1 can perform quantitative analysis on the sample liquid.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
