Description

Technical Field

[0001] The present invention relates to the technical field of water pollution analysis, in particular to a water quality analyzer inspection and calibration device and a method thereof. Background Art

[0002] With the construction of water conservancy projects and the development of industries and towns surrounding river basins, pollutant emissions have increased. Regular sampling and analysis of river basin water quality, monitoring of environmental water quality effects, and protection of water resources are crucial. As a key testing device, water quality analyzers work by first sampling water, adding specific reagents to the sampled liquid, and then mixing it within the instrument. The instrument then emits light of a specific wavelength through a light source. This light passes through the sample and is then received by a receiving light source. Based on the Lambert-Beer law, the concentration of substances in the sample is analyzed based on the liquid's absorbance to determine the water quality.

[0003] Although samples are shaken before testing and analysis, there is a time lag between shaking, subsequent operations, and actual testing. During this time, substances can re-precipitate, leading to uneven distribution, interfering with light propagation and affecting test accuracy. Furthermore, samples are typically placed in tubular containers, similar to covered test tubes, which make vertical shaking less effective and also affect test accuracy. Therefore, specific shake calibration is required for the samples to be tested to improve the accuracy of water quality analyzers. Summary of the Invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0035] Example 1: A water quality analyzer inspection and calibration device, comprising a light emitting element 42 and a light receiving element 23; the device also comprises a base 1 and a housing 2 fixedly connected to the upper surface of the base 1 via a support plate 11; the inner and outer walls of the housing 2 are symmetrically provided with a feed port 21 and a discharge port 22; the inner wall of the housing 2 is rotatably connected to the inner sleeve 3; the front portion of the inner wall of the inner sleeve 3 is fixedly connected to the front center column 4; the front end of the front center column 4 is driven by a motor 41; the rear portion of the inner wall of the inner sleeve 3 is movably connected to the rear center column 5; the rear center column 5 is fixedly connected to the inner wall of the housing 2; The rear center column 5 is provided with an annular corrugated groove 51 on the circumferential outer wall; the corrugated block 52 is movably connected in the corrugated groove 51; the inner sleeve 3 is evenly provided with sliding grooves 31 in the circumference; the sliding groove 31 is slidably connected to the sliding bar 6; the sliding bar 6 is fixedly connected to the corresponding corrugated block 52; the outer wall of the sliding bar 6 is provided with a placement groove 61; the bottom of the placement groove 61 is provided with a light-transmitting groove 62; the light emitting element 42 is provided on the outer wall of the front center column 4; the light receiving element 23 is embedded in the outer shell 2; the light emitting element 42 can transmit light through the placement groove 61 to be received by the light receiving element 23.

[0036] After the water to be analyzed is sampled into the transparent analysis tube, a specific reagent is added into the analysis tube, and then the lid of the analysis tube opening is closed, and the analysis tube is placed horizontally into the feed port 21. The motor 41 drives the front center column 4 to rotate, and the rotation of the front center column 4 drives the inner sleeve 3 to rotate. The rotation of the inner sleeve 3 drives the slide groove 31 on the outer wall and the slide bar 6 to move. The placement groove 61 on the slide bar 6 will be aligned with the feed port 21, and the analysis tube will be placed into the corresponding placement groove 61 along the feed port 21. After the analysis tube falls into the placement groove 61, the slide bar 6 will move along the The inner sleeve 3 rotates and moves. The inner sleeve 3 drives the slide bar 6 to rotate around the center of the inner sleeve 3. The slide bar 6 will drive the corrugated block 52 to move along the corrugated groove 51. The corrugated groove 51 is annular, and the corrugated direction is the axial direction of the inner sleeve 3. Therefore, the corrugated block 52 will move along the circumferential direction of the inner sleeve 3 during the movement along the corrugated groove 51, and also move back and forth along the axial direction of the inner sleeve 3. The slide bar 6 moves with the movement of the corrugated block 52. The slide bar 6 will drive the analysis tube in the placement groove 61 to move back and forth in the axial direction of the inner sleeve 3 during the axial back and forth movement of the inner sleeve 3. The analysis tube moves During the movement, the liquid inside the analysis tube will be driven to move back and forth along the axial direction, so that the liquid in the analysis tube is shaken evenly when the analysis tube is placed horizontally. During the shaking process of the liquid in the analysis tube, the light emitting element 42 will emit light of a specific wavelength, which will pass through the light-transmitting groove 62 and enter the placement groove 61. After passing through the analysis tube, it will be received by the light receiving element 23. The analysis tube moves from top to bottom as the inner sleeve 3 rotates, so that the analysis tube is analyzed for a longer time. In addition, the analysis and analysis are performed during the shaking process of the liquid in the analysis tube, and the analysis and detection accuracy and precision are higher. The slide bar 6 will drive the liquid in the placement tube to be evenly The analysis tube enters the discharge port 22, and the analysis tube will be moved out of the placement groove 61 under the action of its own gravity. The analysis tube will fall from the discharge port 22 onto the elastic rubber pad (not numbered in the figure) on the upper surface of the base 1, completing the water quality analysis and detection of the analysis tube. According to the conversion of the equipment itself, the absorbance value of the liquid in the analysis tube is obtained, and the water quality condition is indirectly obtained. This embodiment performs water quality analysis during the shaking process of the liquid in the analysis tube, so that the liquid in the analysis tube is analyzed in a mixed and uniform state, thereby improving the detection precision and accuracy of the analyzer.

[0037] Example 2: The placement groove 61 is symmetrically provided with a card slot 63; the card slot 63 is slidably connected with a card strip 7; the card strip 7 is composed of a plurality of contact-arranged card blocks 71; the card block 71 is connected to the bottom of the card slot 63 through a first spring 72; a guide surface 73 is provided at the outward end of the card block 71.

[0038] In this embodiment, the card strip 7 is slidably and sealedly connected to the card slot 63; adjacent card blocks 71 are in movable sealed contact; the slide bar 6 is slidably and sealedly connected to the slide slot 31; a connecting groove 32 is provided on the inner wall of the middle section of the slide slot 31; the bottom of the card slot 63 is connected to the corresponding connecting groove 32 through the first connecting hole 64; and multiple connecting grooves 32 are connected through the second connecting hole 33.

[0039] In this embodiment, an adjustment groove 34 is provided inside the rear of the inner sleeve 3; the adjustment groove 34 is slidingly and sealingly connected to the adjustment plate 35; the space of the adjustment groove 34 on the front side of the adjustment plate 35 is connected to the connecting groove 32 through a third connecting hole 36; the rear side of the adjustment plate 35 is rotatably connected to the bolt 37; the bolt 37 passes through the rear end of the inner sleeve 3 and is threadedly connected to the inner sleeve 3.

[0040] Before putting the equipment into use, first tighten the bolt 37. After being tightened, the bolt 37 will drive the adjustment plate 35 to move backward in the adjustment groove 34. The gas in the adjustment groove 34 space on the rear side of the adjustment plate 35 will flow out along the gap between the bolt 37 and the inner sleeve 3. The adjustment groove 34 space on the front side of the adjustment plate 35 will form a negative pressure. Under the action of the negative pressure, the liquid medium in the card slot 63 enters the adjustment groove 34 space on the front side of the adjustment plate 35 along the first connecting hole 64, the connecting groove 32, and the third connecting hole 36. The card block 71 will retract into the corresponding card slot 63 under the negative pressure of the card slot 63, and then align two of the placement slots 61 with the feed port 21, and then put the analysis tubes with lids (stoppers) in sequence. Then, when the placement slots 61 are staggered with the feed port 21 and the discharge port 22, the bolt 37 is screwed. After being screwed, the bolt 37 will drive the adjustment plate 35 to move forward in the adjustment slot 34. During the forward movement of the adjustment plate 35, the liquid medium in the space of the adjustment slot 34 on the front side of the adjustment plate 35 will be squeezed. The clamping block 71 is pressed against the top of the bottle 63 and the clamping block 71 is pressed against the top of the bottle 63. The clamping block 71 is pressed against the top of the bottle 63 and the clamping block 71 is pressed against the bottom of the bottle 63.

[0041] After the loading port 61 is in the working state, the bottle 71 is pushed up and the bottle 72 is pushed down, so that the bottle 71 is pushed down and the bottle 72 is pushed down.

[0042] Example 3: The slide groove 31 is through-through toward the front; the placement groove 61 is penetrated with an air vent 65 toward the front; the placement groove 61 is penetrated with a one-way air outlet 66 toward the rear; the slide groove 31 is penetrated with a one-way air inlet 38 toward the rear; the outer wall of the slide bar 6 and the outer wall of the inner sleeve 3 are both in active sealing contact with the inner wall of the outer shell 2.

[0043] In this embodiment, the feed port 21 of the outer shell 2 is provided with a feed sleeve 8; the inner side of the feed sleeve 8 is connected to two feed plates 81 for sliding forward and backward; the upper end of the feed plate 81 is fixedly connected to the guide plate 82; the two guide plates 82 are in an inverted eight shape; the two feed plates 81 are fixedly connected to the guide rod 83 on one side away from each other; the guide rod 83 passes through the feed sleeve 8 and is slidably connected to the feed sleeve 8; the two feed plates 81 are connected to the inner wall of the feed sleeve 8 on one side away from each other through a second spring 84.

[0044] When the load plate 81 is in the center, the two guide plates 82 are pressed against the load plate 81, and the load plate 81 is pressed against the load plate 82. When the load plate 81 is in the center, the two guide plates 82 are pressed against the load plate 81, and the load plate 81 is pressed against the load plate 81. The air in the cleaning cavity 31 is prevented from being blocked by the one-way air outlet 66 and the air vent 65 and affecting the subsequent air flow. As the inner sleeve 3 rotates, the inner sleeve 3 drives the corrugated block 52 on the slide bar 6 to move along the corrugated groove 51, and the slide bar 6 moves in the forward and backward directions as the inner sleeve 3 rotates. The space formed by the rear end of the slide bar 6 and the rear end of the slide groove 31 is a cleaning cavity. During the forward movement of the slide bar 6, the space in the cleaning cavity is enlarged to form a negative pressure, and the outside air enters the cleaning cavity along the one-way air inlet 38. As the slide bar 6 moves backward, the gas in the cleaning cavity is pressurized and discharged along the one-way air outlet 66. The gas discharged from the one-way air outlet 66 enters the placement groove 61, thereby axially impacting the outer wall of the analysis tube in the placement groove 61. Impurities and water stains on the outer wall of the analysis tube will be discharged along the air vent 65. This avoids residual water stains and impurities on the surface of the analysis tube from affecting the detection accuracy, thereby further improving the detection accuracy of water quality analysis.

[0045] Example 4: The discharge port 22 of the housing 2 is provided with a discharge sleeve 9; the lower end of the discharge sleeve 9 is rotatably connected to the discharge plate 92 via a torsion spring 91.

[0046] In this embodiment, there are multiple discharge plates 92; the torsion force of the torsion springs 91 applied to the multiple discharge plates 92 decreases from the back to the front.

[0047] Before the analysis tube is placed along the feed port 21, the end of the analysis tube with the cover will be placed at the back and the end without the cover will be placed at the front. After the analysis tube is placed into the placement slot 61 aligned with the feed port 21, the placement slot 61 will drive the analysis tube to move from top to bottom and perform detection during the shaking process. The placement slot 61 will drive the analysis tube to the top of the discharge port 22. The analysis tube in the placement slot 61 will move out of the placement slot 61 under the action of its own gravity, and the analysis tube will fall on the upper surface of the discharge plate 92. The discharge plate 92 is connected to the lower end of the discharge sleeve 9 through the torsion spring 91, so the analysis tube will fall on the discharge plate 92. The discharge plate 92 is under the action of the gravity of the analysis tube. The torsion spring 91 is overcome to flip over, and the discharge plate 92 at the rear forms a buffer slope, so that the analysis tube can fall along the slope formed by the discharge plate 92. Since there are multiple discharge plates 92, the torsion force of the multiple discharge plates 92 decreases from back to front due to the torsion spring 91. In this way, after the analysis tube falls on the upper surface of the discharge plate 92, the multiple discharge plates 92 are opened in sequence from front to back. In this way, the end of the analysis tube without a cover will fall first, so that the analysis tube can be stably unloaded, avoiding the situation where the opening of the analysis tube moves out of the placement slot 61 first and causes the analysis tube to be opened, thereby ensuring the stability of the analysis tube after the water quality analysis test.

[0048] Example 5: A method for testing and calibrating a water quality analyzer, which is applicable to the above-mentioned water quality analyzer testing and calibration equipment, and the steps of the method are as follows:

[0049] S1: After sampling, the analysis tube is filled with reagents and covered with a lid. The analysis tube then follows the two guide plates 82 into the feed sleeve 8 and is restrained in the center by the two feed plates 81. The analysis tube falls into the placement tank 61 under its own gravity.

[0050] S2: The analysis tube entering the placement groove 61 through the feed port 21 will press the corresponding block 71, and the analysis tube in the placement groove 61 near the discharge port 22 will be squeezed out; the motor 41 will drive the front center column 4 and the inner sleeve 3 to rotate, and the inner sleeve 3 will drive the corrugated block 52 on the slide bar 6 to move along the corrugated groove 51;

[0051] S3: As the inner sleeve 3 rotates, the slide bar 6 moves back and forth along the axial direction of the inner sleeve 3. The slide bar 6 causes the analysis tube, which is restrained by the block 71 in the placement groove 61, to shake evenly. The gas discharged from the one-way air outlet 66 impacts the impurities and water stains on the outer wall of the analysis tube.

[0052] S4: The light emitting element 42 emits light through the light-transmitting slot 62 into the analysis tube in the placement slot 61, and is finally received by the light receiving element 23. The analysis tube moves to the discharge port 22, overcomes the torsion on the discharge plate 92 and is discharged.
