Description

Technical Field

[0002] Water quality detection is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. When detecting water quality currently, usually a certain amount of water sample is drawn into and discharged from a sampling bottle manually, then a detection agent is dropped into the sampling bottle, and finally the sampling bottle is capped and shaken to mix the water sample and the detection agent evenly in the sampling bottle. By observing the color of the water sample in the sampling bottle and comparing it with a colorimetric card, the detection of water quality is achieved. At the same time, multiple samplings are carried out for the detection items of the water sample as needed and different detection agents are dropped.

[0003] The following problems exist when detecting water quality currently: 1. Since there may be impurities such as particulate matter or suspended matter in the water sample, the water sample usually needs to be filtered before detecting the water quality.

[0028] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0029] See also Figure 1 and Figure 2 A portable water quality rapid detection device includes a water pump 1, a hose 2 is installed through the middle of the right end of the water pump 1, a filter unit 3 is installed on the right side of the inside of the water pump 1, a dropper device 4 is installed on the upper left side of the water pump 1, and a clamping unit 5 for clamping and fixing a sampling bottle is installed on the lower left side of the water pump 1.

[0030] The present invention is used for water quality detection, and the present invention can detect multiple samples at the same time, thereby increasing the detection efficiency of water quality. At the same time, the present invention can also thoroughly filter the water sample to prevent impurities such as particulate matter or suspended matter in the water sample from affecting the detection result, thereby ensuring the accuracy of the detection result. Specifically, firstly, multiple sampling bottles are placed in the clamping unit 5, so that the clamping unit 5 clamps and fixes the sampling bottles, and then the corresponding detection agents are extracted through multiple droppers, and the droppers are placed in the dropper device 4, so that the dropper device 4 clamps and fixes the multiple droppers.

[0031] Next, place the hose 2 in the water area to be detected, and control the water pump 1 to draw water samples, so that the water in the water area passes through the hose 2 and enters the water pump 1. At the same time, the filtering unit 3 can thoroughly filter the water samples, and the filtered water samples flow into multiple sampling bottles clamped by the clamping unit 5. Finally, control the dropping device 4 to drop the detection agent into the corresponding sampling bottles, let it stand for a period of time, then take out the sampling bottles from the clamping unit 5, observe the color of the solution in the sampling bottles and compare it with the color comparison card, so as to realize the detection of water quality. After the water quality detection is completed, clean the inside of the water pump 1 with distilled water to ensure the accuracy of the subsequent detection results of other water qualities.

[0032] Refer to Figure 2 , an arc-shaped groove is formed in the right part of the inner side of the water pump 1, and an arc-shaped sealing cover 11 is detachably installed at the position corresponding to the arc-shaped groove on the upper part of the water pump 1. A piston 10 is slidably installed left and right on the left side inside the water pump 1, and a pull rod 101 is fixedly installed on the left part of the piston 10. The left end of the pull rod 101 slidably penetrates through the left end of the water pump 1 left and right.

[0033] Refer to Figure 2 and Figure 3 , the filtering unit 3 includes a clamping unit 31 slidably arranged left and right in the arc-shaped groove in a detachable manner. A circular plate 32 is installed on the right side of the clamping unit 31. A filter cotton sheet 33 is installed between the clamping unit 31 and the circular plate 32 in a detachable manner. The clamping unit 31 is used to clamp and fix the filter cotton sheet 33, and a cleaning unit 34 for preventing the filter cotton sheet 33 from being blocked is installed on the circular plate 32.

[0034] The filtering unit 3 is used to thoroughly filter the water samples; specifically, initially the piston 10 is at the right extreme position. By manually pulling the pull rod 101 to the left, the pull rod 101 drives the piston 10 to move to the left, so that the water in the water area is pumped into the water pump 1 under the action of the internal pressure of the water pump 1 through the hose 2. The water sample can pass through the filter cotton sheet 33 from right to left, so that the filter cotton sheet 33 thoroughly filters impurities such as particulate matter or suspended matter in the water sample, increasing the accuracy of the detection results. At the same time, the cleaning unit 34 can clean the impurities on the filter cotton sheet 33, thereby preventing the filter cotton sheet 33 from being blocked due to excessive accumulation of impurities.

[0035] After the water sample detection is completed, the arc-shaped sealing cover 11 is manually opened, and the clamping unit 31, the annular plate 32, and the filter cotton sheet 33 are taken out, so as to facilitate manual cleaning of the impurities in the water pumping cylinder 1. By injecting distilled water into the water pumping cylinder 1, the inside of the water pumping cylinder 1 is cleaned, thereby ensuring the accuracy of the subsequent detection results of other water qualities. By manually controlling the clamping unit 31 not to clamp and fix the filter cotton sheet 33, the filter cotton sheet 33 can be replaced. Then, the clamping unit 31 is controlled again to clamp and fix the new filter cotton sheet 33, and the clamping unit 31, the annular plate 32, and the new filter cotton sheet 33 are placed in the corresponding arc-shaped grooves, so as to ensure the filtering effect of the filter cotton sheet 33 on the water sample.

[0036] Refer to Figure 3 As shown in the figure, two adjusting plates 14 are symmetrically arranged up and down on the right side inside the water pumping cylinder 1. A plurality of filter plates 15 are uniformly arranged front and back on the opposite sides of the two adjusting plates 14. The left and right sides of the filter plates 15 are triangular structures, and the filter plates 15 corresponding to the upper and lower two adjusting plates 14 are arranged staggeredly. Adjusting screws 16 are rotatably installed on the opposite sides of the two adjusting plates 14, and the adjusting screws 16 are connected to the water pumping cylinder 1 by means of threaded cooperation. A baffle 17 with an arc-shaped structure is fixedly installed on the lower side inside the water pumping cylinder 1 and to the right of the arc-shaped groove.

[0037] When the water sample is pumped from the hose 2 into the water pumping cylinder 1, the staggeredly arranged filter plates 15 can first filter the larger impurities in the water sample, so that the larger impurities in the water sample can fall into the part of the water pumping cylinder 1 on the right side of the baffle 17, thereby preventing the larger impurities from damaging the filter cotton sheet 33 and causing the filter cotton sheet 33 to be unable to effectively filter the water sample. At the same time, by synchronously screwing the two adjusting screws 16 to drive the two adjusting plates 14 to move away from each other, the gap between two adjacent filter plates 15 is adjusted, so as to ensure the thorough filtration of the larger impurities in the water sample and ensure the efficiency of the water sample passing through the filter plates 15. When the arc-shaped sealing cover 11 is opened, the larger impurities on the right side of the baffle 17 are manually cleaned.

[0038] Refer to Figure 4 As shown in the figure, the clamping unit 31 includes a clamping ring 311 in contact with the left side of the annular plate 32. The clamping ring 311 is connected to the annular plate 32 by two symmetrically arranged clamping spring rods 312 front and back. The filter cotton sheet 33 is arranged between the clamping ring 311 and the annular plate 32. Two symmetrically arranged positioning holes are opened at the left end of the clamping ring 311. Two symmetrically arranged top spring rods 18 are slidably installed left and right on the left inner wall of the arc-shaped groove, and the right end of the top spring rod 18 is spherical. The top spring rod 18 is used to cooperate with the positioning hole to tightly abut the clamping ring 311 to the right.

[0039] The clamping unit 31 is used to clamp and fix the filter cotton sheet 33. Specifically, by manually moving the clamping ring 311 to the left and compressing the clamping spring rod 312, then placing the filter cotton sheet 33 centered between the clamping ring 311 and the annular plate 32 and releasing the clamping ring 311, the clamping ring 311 cooperates with the annular plate 32 under the action of the clamping spring rod 312 to clamp and fix the filter cotton sheet 33. When the clamping ring 311, the filter cotton sheet 33 and the annular plate 32 are placed in the corresponding arc-shaped grooves, the positioning hole is aligned with the top extension spring rod 18 manually, so that the top extension spring rod 18 can be inserted into the positioning hole and abut against the clamping ring 311 to the right, realizing the installation of the filter cotton sheet 33. The right end of the top extension spring rod 18 is set as a spherical structure, so that the clamping ring 311, the filter cotton sheet 33 and the annular plate 32 can be quickly placed in the corresponding arc-shaped grooves or taken out from the arc-shaped grooves. Repeat the above operations and place the new filter cotton sheet 33 between the clamping ring 311 and the annular plate 32, thus realizing the replacement of the filter cotton sheet 33.

[0040] Refer to Figure 5 , the cleaning unit 34 includes a rotating ring 341 rotatably installed inside the annular plate 32. A plurality of cleaning plates 342 are fixedly installed on the left side of the rotating ring 341 and are arranged circumferentially and evenly. The cleaning plates 342 are in contact with the filter cotton sheet 33. The opposite sides of the plurality of cleaning plates 342 are all set as triangular structures and are in contact with each other.

[0041] Refer to Figure 3 , Figure 5 and Figure 6 , a matching rod 343 is fixedly installed on the outer side of the upper part of the rotating ring 341, and one end of the matching rod 343 away from the rotating ring 341 slides through the annular plate 32. An arc-shaped plate 111 is fixedly installed inside the arc-shaped sealing cover 11. The rear sides of the left and right ends of the arc-shaped plate 111 are both set as inclined surfaces for cooperating with the matching rod 343 to drive the rotating ring 341 to rotate.

[0042] The cleaning unit 34 is used to clean the impurities on the filter cotton sheet 33. Specifically, when the water sample passes through the filter cotton sheet 33, the filter cotton sheet 33 can filter the impurities in the water sample. When too many impurities accumulate, the impurities will block part of the filter cotton sheet 33. At this time, the water sample can pass through the unblocked part of the filter cotton sheet 33, and the unblocked part of the filter cotton sheet 33 will filter the water sample again. And when the filter cotton sheet 33 is blocked to a certain extent, due to the piston 10 continuing to move leftward, the pressure borne by the filter cotton sheet increases at this time, so that the filter cotton sheet 33 can drive the annular plate 32 and the clamping ring 311 to move leftward and compress the corresponding top spring rod 18 under the action of the pressure. At the same time, the annular plate 32 drives the matching rod 343 to move leftward through the rotating ring 341, so that the matching rod 343 drives the rotating ring 341 to rotate backward under the action of the inclined surface of the arc plate 111, and further makes the rotating ring 341 drive the cleaning plate 342 to rotate backward. And because the opposite sides of the plurality of cleaning plates 342 are all arranged in a triangular structure and are in contact with each other, and the cleaning plate 342 is in contact with the filter cotton sheet 33, the cleaning plate 342 can thoroughly clean the impurities accumulated on the filter cotton sheet 33. When the impurities on the filter cotton sheet 33 are cleaned up, at this time, the clamping ring 311 drives the filter cotton sheet 33 and the annular plate 32 to return to the initial position to the right under the action of the top spring rod 18.

[0043] Refer to Figure 1 , Figure 2 and Figure 7 , an arc-shaped guide groove 19 is provided at the lower left part of the water pumping cylinder 1, and an arc-shaped sealing door 12 is detachably installed at the front left part of the water pumping cylinder 1 corresponding to the position of the guide groove 19, and an observation window is hermetically installed on the arc-shaped sealing door 12. Among them, a drain valve is installed at the lower part of the water pumping cylinder 1 and on the left side of the guide groove 19.

[0044] Refer to Figure 2 and Figure 7 , the clamping unit 5 includes an arc-shaped mounting plate 51 slidably installed in the guide groove 19, an arc-shaped spring 52 is connected between the mounting plate 51 and the guide groove 19, a plurality of mounting holes are uniformly arranged left and right on the mounting plate 51, and a plurality of rubber strips 53 are circumferentially and uniformly arranged and fixedly installed in the mounting holes. The upper ends of the opposite sides of the plurality of rubber strips 53 are arranged as inclined surfaces, and the rubber strips 53 are used for clamping and fixing the sampling bottle.

[0045] The clamping unit 5 is used to clamp and fix the sampling bottle; specifically, first, the arc-shaped sealing door 12 is opened, and then, according to the detection items of the water quality of the water sample required by the operator, the corresponding number of sampling bottles are placed in the mounting holes, so that multiple rubber strips 53 can clamp and fix the sampling bottles, and the inclined surfaces on the rubber strips 53 facilitate the placement of the sampling bottles. When extracting water samples from the water area, the arc-shaped sealing door 12 is closed, and the water sample can move along the inner wall of the water pumping cylinder 1 into the sampling bottle, and the water sample taken in the sampling bottle can be observed through the observation window on the arc-shaped sealing door 12.

[0046] When a certain amount of water sample is injected into the sampling bottle, stop extracting the water sample, and release the excess water sample in the water pumping cylinder 1 by opening the drain valve. At the same time, slightly rotate the water pumping cylinder 1 back and forth by a certain angle manually to make the sampling bottle in an inclined state, so that part of the water in the sampling bottle can be poured out, preventing the sampling bottle from being filled with water sample and causing the detection agent to be unable to drip. Then, control the dropping agent device 4 to drop the detection agent into the sampling bottle and let it stand for a period of time. Then, open the arc-shaped sealing door 12 and take out the sampling bottle, observe the color of the solution in the sampling bottle and compare it with the colorimetric card, so as to realize the detection of water quality. And by injecting distilled water into the water pumping cylinder 1 and cleaning the water pumping cylinder 1, the accuracy of subsequent water quality detection results is ensured.

[0047] Refer to Figure 1 、 Figure 7 and Figure 8 As shown in, the dropping agent device 4 includes a connection frame 41 fixedly installed at the rear part on the left side of the inner wall of the water pumping cylinder 1. The front end of the connection frame 41 is slidably installed with an integrated board 43 up and down through a plurality of connection springs 42. The front end of the integrated board 43 is slidably installed with a plurality of adjusting blocks 44 arranged evenly left and right up and down. A threaded rod 45 is threadedly connected to the adjusting block 44, and the threaded rod 45 is rotatably connected to the integrated board 43. The front end of the adjusting block 44 is fixedly installed with a dropper soft clip 46. A squeezing unit 13 for squeezing the dropper is installed at the position corresponding to the integrated board 43 on the upper part of the water pumping cylinder 1; wherein, the dropper in the present invention adopts a pressing dropper.

[0048] Refer to Figure 7 As shown in, the squeezing unit 13 includes a squeezing plate 131 distributed above the integrated board 43. The middle part of the upper end of the squeezing plate 131 is fixedly installed with a square spring rod 132, and the upper end of the square spring rod 132 slidably penetrates through the water pumping cylinder 1 up and down.

[0049] The dropping device 4 is used to hold the dropper and drop the detection agent into the sampling bottle. Specifically, when the arc-shaped sealing door 12 is opened, multiple droppers are manually controlled to extract the corresponding detection agent, and the multiple droppers are sequentially placed in the corresponding dropper soft clips 46 in turn, so that the dropper soft clips 46 clamp and fix the multiple droppers. Then the arc-shaped sealing door 12 is closed. When it is necessary to drop the detection agent into the water sample in the sampling bottle, by manually pressing down the square spring rod 132, the square spring rod 132 drives the pressing plate 131 to move downward and squeeze the upper end of the dropper, so that the dropper drops the detection agent into the sampling bottle. And when the dropper soft clip 46 clamps and fixes the dropper, at the same time, by manually screwing the threaded rod 45 to drive the adjusting block 44 to move up and down to realize the height adjustment of the adjusting block 44, so that the adjusting block 44 adjusts the height of the dropper through the dropper soft clip 46, and controls the height of the upper end of the dropper relative to the upper end of the integrated board 43 according to the amount of the detection agent to be dropped into the water sample, so as to realize the precise control of the amount of the detection agent dropped by the dropper, further ensure the accuracy of the detection result. Finally, the square spring rod 132 is released, so that the square spring rod 132 drives the pressing plate 131 to return to the initial position upward under its elastic action.

[0050] Refer to Figures 7 - 9 , on the upper side of the mounting plate 51 and on the left side of the mounting hole, L-shaped plugging plates 55 are slidably mounted left and right through return springs 54. The plugging plates 55 are used to seal the sampling bottle. At the positions corresponding to the plugging plates 55 at the lower end of the integrated board 43, matching plates 431 are fixedly mounted through square rods. The right side of the lower end of the matching plate 431 is provided with an inclined surface for driving the plugging plate 55 to move to the right.

[0051] Refer to Figures 7 - 9 , in the middle of the rear side of the upper end of the mounting plate 51, an L-shaped rod 56 is fixedly mounted. At the position corresponding to the L-shaped rod 56 at the lower end of the integrated board 43, a fixing plate 432 is fixedly mounted. At the front end of the fixing plate 432, a plurality of uniformly arranged toggle blocks 433 are fixedly mounted up and down. The front end of the toggle block 433 is provided with a trapezoidal structure for cooperating with the horizontal section of the L-shaped rod 56 to drive the L-shaped rod 56 to move forward.

[0052] When the pressing plate 131 moves downward to the upper end of the integrated board 43, at this time, the dropping of the detection agent is completed. Continue to control the square spring rod 132 to drive the pressing plate 131 to move downward, so that the pressing plate 131 drives the integrated board 43 to move downward and compress the connecting spring 42. The integrated board 43 drives the matching plate 431 to move downward through the square rod, so that the inclined surface of the matching plate 431 drives the plugging plate 55 to move to the right, so that the plugging plate 55 seals the opening of the sampling bottle. Then the integrated board 43 drives the lowermost toggle block 433 to move to the position corresponding to the horizontal section of the L-shaped rod 56 through the fixing plate 432.

[0053] When the squeezing plate 131 drives the integrated plate 43 to continue to move downward, the horizontal section of the L-shaped rod 56 drives the mounting plate 51 to move forward along the guide groove 19 and compresses the arc spring 52 under the cooperation of the trapezoidal structure of the toggle block 433. When the horizontal section of the L-shaped rod 56 and the toggle block 433 are separated, the mounting plate 51 returns to its initial position under the action of the arc spring 52, and the toggle block 433 is provided with multiple ones, so that the sampling bottle can be shaken to make the water sample and the detection agent in the sampling bottle mix quickly, thereby further increasing the water quality detection efficiency. At the same time, the sealing plate 55 always blocks the opening of the sampling bottle under the action of the matching plate 431, thereby preventing the water sample from spilling. Finally, the square spring rod 132 is released, so that the square spring rod 132 drives the squeezing plate 131 to return to its initial position upward under its elastic action. At the same time, the integrated plate 43 returns to its initial position under the action of the connecting spring 42, and the sealing plate 55 returns to its initial position under the action of the reset spring 54, thereby facilitating the removal of the sampling bottle.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
