Description

Technical Field

[0001] This utility model relates to the field of water quality testing and analysis technology, and in particular to a multi-parameter water quality testing and analysis device. Background Technology

[0002] In the process of environmental protection, in order to accurately understand the water quality, water samples are taken and then analyzed using analyzers to detect and analyze parameters such as pH, residual chlorine, turbidity, and temperature. Based on these values, corresponding measures are then taken.

[0003] Traditional water analyzers, when testing water samples, first insert a water tube containing the sample into the test tube holder, then operate the analyzer's control panel to perform the test, and finally output the result report from the output port. However, in actual use, it has been found that different batches of water samples require test tubes of different sizes, while the analyzer's test tube holder size is fixed. This makes it difficult to adapt the test tubes during installation and testing, affecting the normal operation of the analyzer and impacting the accuracy and reliability of the test results. Utility Model Content

[0004] This invention addresses the problem that different sizes of test tubes are used in different batches of water sampling, while the size of the test tube slot in the analyzer is fixed. This makes it difficult to adapt the test tubes for use during installation and testing, affecting the normal operation of the analyzer and the accuracy and reliability of the test results. Therefore, a multi-parameter water quality detection and analysis device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-parameter water quality detection and analysis device, comprising an analyzer, an operation screen fixedly connected to the surface of the analyzer, a test tube groove provided on one inner wall of the analyzer, a paper outlet opened on the surface of the analyzer, a stabilizing device provided on the inner wall of the analyzer at the position of the test tube groove, the stabilizing device comprising two mounting shafts, the two mounting shafts being fixedly connected to the surface of the analyzer respectively, connecting plates being rotatably connected to the arc surfaces of the two mounting shafts respectively, an arc plate being fixedly connected to the surface of the connecting plates, a servo motor being fixedly connected to the surface of the analyzer, a screw being fixedly connected to the output end of the servo motor, a fixing frame being threaded through the arc surface of the screw, a limit rod being slidably connected through the surface of the fixing frame, and the limit rod being fixedly connected to the surface of the analyzer.

[0006] The aforementioned components achieve the following effect: when the analyzer is detecting and analyzing wastewater, test tubes of different sizes can be stably assembled on the equipment without shaking or shifting, thus ensuring stable detection of water samples, improving the accuracy and reliability of the test results, and further enhancing the effectiveness and functionality of the analyzer.

[0007] Preferably, a reinforcing pad, which is a rubber pad, is fixedly connected to the inner wall of the arc-shaped plate.

[0008] The effect achieved by the above components is that, by setting up the reinforcing pad, the friction is further increased when the two arc-shaped plates clamp and fix the test tube, thereby making the test tube more firmly fixed and easier to detect and analyze.

[0009] Preferably, stabilizing grooves are provided on both sides of the surface of the fixing frame, and the specifications and dimensions of the stabilizing grooves are adapted to the connecting plate.

[0010] The effect achieved by the above components is that, by setting the stabilizing groove, when the fixing frame contacts and is pressed against the surface of the connecting plate, the stabilizing groove can be locked onto the surface of the connecting plate, thereby making the fixing frame more stable and ensuring the stability of the test tube assembly.

[0011] Preferably, a stop block is fixedly connected to the output end of the screw away from the servo motor, and the size of the stop block is larger than the size of the screw.

[0012] The effect achieved by the above components is that, by setting the stop, when the servo motor drives the movement of the fixed frame, it is not easy for the screw to rotate excessively, causing the fixed frame to rotate and disengage, thus affecting the normal use of the stabilization device.

[0013] Preferably, torsion springs are respectively fitted on the arc surfaces of the two mounting shafts on both sides of the connecting plate, and the two ends of the torsion springs are fixedly connected to the mounting shafts and the surface of the connecting plate, respectively.

[0014] The effect achieved by the above components is as follows: by setting the torsion spring, when the test tube is taken out of the test tube slot, the fixing bracket is disengaged from the surface of the connecting plate, and the connecting plate will rotate under the torsional force of the torsion spring, thereby making the arc plate separate quickly and facilitating the insertion and removal of the test tube.

[0015] Preferably, a protective device is provided on the surface of the analyzer at the position of the operation screen. The protective device includes a mounting plate, which is fixedly connected to the surface of the analyzer. A connecting shaft is rotatably connected to the surface of the mounting plate. A protective plate is fixedly connected to one side of the connecting shaft. A fixing plate is fixedly connected to one side of the protective plate. A fixing frame is fixedly connected to the surface of the analyzer. The fixing plate is engaged with the inner wall of the fixing frame.

[0016] The effect achieved by the above components is that the operation screen is less likely to come into contact with or collide with other objects during use, thus preventing abnormal damage to the operation screen, affecting the normal use of the analyzer, and impairing the accuracy of the test results.

[0017] Preferably, a handle is fixedly connected to the surface of the protective plate, and the surface of the handle is provided with a plurality of protective protrusions.

[0018] The effect achieved by the above components is that the handle makes it easier to flip the protective plate, thereby making the use and protection of the control panel more convenient and quick.

[0019] Preferably, a protective plate is fixedly connected to the side of the protective plate near the operating screen, and the protective plate is a sponge board.

[0020] The effect achieved by the above components is that, by setting up the protective plate, when the protective plate covers the surface of the operating screen, it is less likely to have gaps, thereby better protecting the surface of the operating screen.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When the analyzer is used to test and analyze wastewater, it can stably assemble test tubes of different sizes on the equipment without shaking or shifting, thus ensuring stable testing of water samples, improving the accuracy and reliability of test results, and further enhancing the effectiveness and functionality of the analyzer.

[0028] Reference Figure 1 As shown, this embodiment discloses a multi-parameter water quality detection and analysis device, including an analyzer 1, an operation screen 2 fixedly connected to the surface of the analyzer 1, a test tube groove 3 provided on one inner wall of the analyzer 1, a paper outlet 4 opened on the surface of the analyzer 1, a stabilizing device 5 provided on the inner wall of the analyzer 1 at the position of the test tube groove 3, and a protective device 6 provided on the surface of the analyzer 1 at the position of the operation screen 2.

[0029] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses a stabilizing device 5 comprising two mounting shafts 51, which are respectively fixedly connected to the surface of the analyzer 1. Connecting plates 52 are rotatably connected to the arc surfaces of the two mounting shafts 51, and arc-shaped plates 53 are fixedly connected to the surface of the connecting plates 52. A servo motor 54 is fixedly connected to the surface of the analyzer 1, and a screw 55 is fixedly connected to the output end of the servo motor 54. A fixing frame 56 is threaded through the arc surface of the screw 55, and a limit rod 57 is slidably connected through the surface of the fixing frame 56. The limit rod 57 is fixedly connected to the surface of the analyzer 1. When using the analyzer 1 to perform water quality analysis on wastewater, firstly, a water tube containing the water sample is inserted into the test tube trough 3, and then the servo motor 54 on the analyzer 1 is started. The operation of the servo motor 54 will drive the screw 55 at its output end. Rotation occurs because the limiting rod 57 limits the movement of the fixed frame 56. Therefore, the rotation of the screw 55 will drive the fixed frame 56 to move closer to the surface of the connecting plate 52 until it contacts the connecting plate 52. This causes the connecting plate 52 to rotate on the arc surface of the mounting shaft 51 on the analyzer 1 until the arc plates 53 on both sides of the test tube contact and press against the test tube, fixing the position of the test tube. Then, the operation screen 2 on the analyzer 1 is set to operate the analyzer 1 to test the water sample. The result report paper will then be output from the paper outlet 4. At this time, when the analyzer 1 is testing and analyzing sewage, test tubes of different specifications and sizes can be stably assembled on the equipment without shaking or shifting, thus ensuring stable testing of the water sample, improving the accuracy and reliability of the test results, and further improving the use effect and functionality of the analyzer 1.

[0030] Reference Figure 1 and Figure 2 as well as Figure 3As shown in the figure, this embodiment discloses that the inner wall of the arc plate 53 is fixedly connected with a reinforcing pad 510, which is a rubber pad. By setting the reinforcing pad 510, the friction force is further increased when the two arc plates 53 clamp and fix the test tube, so that the test tube is more firmly limited and easier to detect and analyze. The two sides of the surface of the fixing frame 56 are respectively provided with stabilizing grooves 58. The specifications and dimensions of the stabilizing grooves 58 are adapted to the connecting plate 52. By setting the stabilizing grooves 58, when the fixing frame 56 contacts and presses against the surface of the connecting plate 52, the stabilizing grooves 58 can be stuck on the surface of the connecting plate 52, so that the fixing frame 56 is more stable and the stability of the test tube assembly is guaranteed.

[0031] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses that a stop 59 is fixedly connected to the output end of the screw 55 away from the servo motor 54. The size of the stop 59 is larger than that of the screw 55. By setting the stop 59, when the servo motor 54 drives the fixed frame 56 to move, it is not easy for the screw 55 to rotate excessively, causing the fixed frame 56 to rotate and disengage, which would affect the normal use of the stabilizing device 5. The arc surfaces of the two mounting shafts 51 are respectively fitted with torsion springs 511 on both sides of the connecting plate 52. The two ends of the torsion springs 511 are fixedly connected to the mounting shafts 51 and the surface of the connecting plate 52, respectively. By setting the torsion springs 511, when the test tube is taken out from the test tube slot 3, the fixed frame 56 disengages from the surface of the connecting plate 52. The connecting plate 52 will rotate under the torsional force of the torsion springs 511, thereby causing the arc plate 53 to separate quickly, which facilitates the insertion and removal of the test tube.

[0032] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this embodiment discloses a protective device 6 including a mounting plate 61, which is fixedly connected to the surface of the analyzer 1. A connecting shaft 62 is rotatably connected to the surface of the mounting plate 61. A protective plate 63 is fixedly connected to one side of the connecting shaft 62, and a fixing plate 64 is fixedly connected to one side of the protective plate 63. A fixing frame 65 is fixedly connected to the surface of the analyzer 1, and the fixing plate 64 is engaged with the inner wall of the fixing frame 65. When the analyzer 1 is analyzing and testing the water quality, rotating the protective plate 63 causes the connecting shaft 62 fixedly connected to the protective plate 63 to rotate on the surface of the mounting plate 61 fixedly connected to the surface of the analyzer 1 until the protective plate 63 covers the surface of the operating screen 2. This causes the fixing plate 64 fixedly connected to one side of the protective plate 63 to be engaged in the inner wall of the fixing frame 65 on the surface of the analyzer 1. At this time, when the analyzer 1 is in use, the operating screen 2 is less likely to be contacted or collided with by other objects, resulting in abnormal damage to the operating screen 2, affecting the normal use of the analyzer 1, and impairing the accuracy of the test results.

[0033] Reference Figure 1 and Figure 2 as well as Figure 4 As shown in the figure, this embodiment discloses that a handle 66 is fixedly connected to the surface of the protective plate 63. The surface of the handle 66 is provided with several protective protrusions. The handle 66 makes it easier to flip the protective plate 63, thereby making the use and protection of the operation screen 2 more convenient and quick. A protective plate 67 is fixedly connected to the side of the protective plate 63 near the operation screen 2. The protective plate 67 is a sponge board. The protective plate 67 makes it less likely for gaps to occur when the protective plate 63 covers the surface of the operation screen 2, thereby better protecting the surface of the operation screen 2.

[0034] Working principle: When using analyzer 1 to analyze wastewater quality, first insert the water tube containing the water sample into test tube tank 3. Then, start the servo motor 54 on analyzer 1. The operation of servo motor 54 will drive the screw 55 on its output end to rotate. Because the limit rod 57 limits the movement of the fixed frame 56, the rotation of screw 55 will drive the fixed frame 56 to move closer to the surface of connecting plate 52 until it contacts the connecting plate 52, causing the connecting plate 52 to rotate on the arc surface of the mounting shaft 51 on analyzer 1. Until the arc-shaped plates 53 on both sides of the test tube contact and press against the test tube, fixing the position of the test tube, then operate and set the operation screen 2 on the analyzer 1 to enable the analyzer 1 to test the water sample. Then the result report paper will be output from the paper outlet 4. At this time, when the analyzer 1 is testing and analyzing sewage, test tubes of different specifications and sizes can be stably assembled on the equipment, and it is not easy to shake or shift, thereby ensuring stable testing of water samples, improving the accuracy and reliability of test results, and further improving the use effect and functionality of the analyzer 1.

[0035] When the analyzer 1 is analyzing and testing the water quality, rotating the protective plate 63 causes the connecting shaft 62 fixedly connected to the protective plate 63 to rotate on the surface of the mounting plate 61 fixedly connected to the surface of the analyzer 1 until the protective plate 63 covers the surface of the operating screen 2. This causes the fixing plate 64 fixedly connected to one side of the protective plate 63 to be stuck in the inner wall of the fixing frame 65 on the surface of the analyzer 1. At this time, when the analyzer 1 is in use, the operating screen 2 is less likely to come into contact with or collide with other objects, which could lead to abnormal damage to the operating screen 2, affecting the normal use of the analyzer 1 and impairing the accuracy of the test results.
