Description
Technical Field
[0001] The utility model relates to the technical field of water pollution detection, in particular to a device for detecting pollutant concentration in water. Background Art
[0002] Water pollutants are substances that, upon entering a water body, can directly or indirectly alter the normal composition and properties of the water, potentially harming humans. These substances can be generated by human activities, while others are naturally occurring. Whether they constitute a water pollutant depends primarily on whether they pose a threat to humans. Some substances, upon entering a water body, can transform into new, more harmful pollutants through chemical, physical, and biological reactions, while others can degrade into harmless substances. Detecting water pollutant concentrations generally relies on large-scale detection equipment.
[0003] In the prior art: a Chinese patent document with announcement number: CN217384846U and publication date of September 6, 2022 is proposed. The technical solution disclosed in the patent document is as follows: it includes a sewage tank, the sewage tank is equipped with a mounting block, the mounting block is provided with a rotating chamber, the sewage tank is provided with a connecting port, the mounting block is provided with a movable groove, the mounting block is equipped with a first motor, the first motor is equipped with a first screw rod, the first screw rod is equipped with a threaded sleeve, the threaded sleeve is equipped with a connecting plate, the connecting plate is equipped with an inverted L-shaped block, the inverted L-shaped block is provided with a traction groove, the traction groove is equipped with an elastic spring, the connecting plate is equipped with a piston rod, the piston rod is equipped with a rubber piston, the piston rod and the rubber piston are equipped with a piston tube, the connecting plate is equipped with a cylinder, and the cylinder is equipped with a connecting rod. The above-mentioned new pollutant concentration detection device in wastewater solves the problem that the existing sampling water acquisition position is the same, the data has errors, and the data is affected by the cooperation of the first screw rod and the connecting rod.
[0004] In the above technology, a piston tube that has extracted contaminated water is driven by a screw rod to move outward from the sewage tank, and then the contaminated water inside the piston tube is dripped into a concentration detector for concentration detection. At the same time, the piston tube is used to extract at different positions inside the sewage tank. The above technology can be used to detect pollutant concentrations, but the efficiency of the above technology is too low in actual detection work. The piston tube needs to be read repeatedly to detect pollutants, and after extracting one position, it is impossible to ensure that the concentration of pollutants in the sewage at other positions remains at the initial state during the waiting process. Therefore, a device that can simultaneously extract sewage from different positions inside the sewage tank is needed, which can greatly improve work efficiency. Therefore, a device for detecting pollutant concentrations in water is proposed. Utility Model Content

The shape of the second fixed plate 4 is also a U-shaped structure, and the long side of the second fixed plate 4 is connected to the output end of the first hydraulic cylinder 3. A rotating rod 5 is fixed between the inner sides of the two short sides of the second fixed plate 4 using a bearing ring. One end of the rotating rod 5 extends to the outside of the second fixed plate 4, and then the extended end is connected to the output end of the first drive motor 7 with a screw. After starting the first drive motor 7, the rotating rod 5 can be driven to rotate between the second fixed plates 4;
[0021] A pumping assembly 6 is provided on the surface of the rotating rod 5. There are four pumping assemblies 6. The pumping assembly 6 can be freely moved on the surface of the rotating rod 5. The pumping assembly 6 includes a fixing ring 601. The fixing ring 601 is composed of two identical semicircular rings. After the two semicircular rings are put together, they fit together with the surface of the rotating rod 5. One end of the two semicircular rings is connected by a hinge, and the other end is also connected together by screws and nuts. When it is necessary to move the fixing ring 601, the screws and nuts used for fixing are loosened, and then the fixing ring 601 is slid on the surface of the rotating rod 5 to move the position. A collecting cylinder 602 is welded to the bottom of the collecting cylinder 602. The collecting cylinder 602 is a needle-shaped structure available on the market. A second hydraulic cylinder 603 is fixed to the bottom of the fixing ring 601 and at the position of the collecting cylinder 602 with screws. A piston 604 is glued to the output end of the second hydraulic cylinder 603. The side of the piston 604 fits together with the inner wall of the collecting cylinder 602. After the second hydraulic cylinder 603 is driven, it can drive the piston 604 to move up and down inside the collecting cylinder 602. During the up and down movement of the piston 604, the sewage can be sucked into the interior through the water inlet hole at the bottom of the collecting cylinder 602, thereby achieving the purpose of collecting sewage;
[0022] The support plate 8 is fixed to the side of the sewage tank 1 using screws and an L-shaped iron sheet for fixing. Two slide rails 9 are welded on the top of the support plate 8. The interior of the slide rail 9 is a concave structure. A slide plate 10 is placed above the slide rail 9. A T-shaped block is welded to the bottom of the slide plate 10, and the slide plate 10 is stuck in the interior of the slide rail 9 through the T-shaped block. A concentration detector 11 is fixed to the surface of the slide plate 10 with screws, and the number of the slide plate 10 and the concentration detector 11 are also four.

A second scale plate 13 is glued to the side of the long side of the second fixed plate 4. The scale value and length of the second scale plate 13 are the same as those of the first scale plate 12, so that the concentration detector 11 and the pumping assembly 6 can be moved using the same reference. After the pumping assembly 6 is moved, the position of the concentration detector 11 is adjusted according to the position of the pumping assembly 6. After adjusting the concentration detector 11, the first hydraulic cylinder 3 is started to drive the pumping assembly 6 to move downward for sewage collection, and then the first hydraulic cylinder 3 is raised again, and then the first drive motor 7 is started to drive the rotating rod 5 to rotate.

[0025] Working principle: When in use, the utility model first places the sewage tank 1 at the place where sewage needs to be tested, and then discharges the sewage into the sewage tank 1 through the water inlet pipe 14. According to the detection needs, it is decided whether to start the second drive motor 16 to drive the stirring frame 17 to rotate to stir the sewage inside the sewage tank 1, and then adjust the positions of the four pumping components 6 according to the detection needs. The pumping components 6 are adjusted according to the second scale plate 13 on the side of the second fixed plate 4, and the sliding fixing ring 601 is fixed with screws after moving. Then, the first hydraulic cylinder 3 under the first fixed plate 2 is started to drive the pumping component 6 to move down until it enters the sewage, and then the second hydraulic cylinder 6 is started. 03, drives the piston 604 to contract inside the collecting tube 602, draws the sewage into the collecting tube 602, and then starts the first hydraulic cylinder 3 again to drive the pumping assembly 6 to rise. After rising to the target position, starts the first drive motor 7 to drive the rotating rod 5 to rotate, and then drives the pumping assembly 6 to tilt. Then, according to the position of the pumping assembly 6, adjust the position of the concentration detector 11, slide the slide 10 under the restriction of the slide rail 9, and adjust it according to the first scale plate 12 on the side of the support plate 8. After adjusting the position, start the second hydraulic cylinder 603 again to drive the piston 604 to move, and spray the sewage inside the collecting tube 602 to the concentration detector 11 to conduct a pollutant concentration test.
