Description

Technical Field

[0001] This utility model relates to the field of data acquisition device technology, specifically to a data acquisition device for a multi-parameter water quality analyzer. Background Technology

[0002] A multi-parameter water quality analyzer is an instrument used to simultaneously measure multiple water quality parameters in a water body.

[0003] Patent CN220136738U discloses a sampling device for a multi-parameter water quality analyzer, relating to the field of water quality sampling technology. The device includes a float, a telescopic hose, and a threaded block. An installation groove is installed at the center of the bottom of the float, and a connecting plate is installed at the top. The connecting plate has a third cavity inside, and a first servo motor is installed at the bottom of the third cavity. A one-way threaded rod is installed at the output end of the first servo motor, and a threaded block is threadedly connected to the outer wall of the one-way threaded rod. Pump heads are installed on both sides of the threaded block, and telescopic hoses are installed at the top of each pump head. A connecting pipe is installed at the top of each telescopic hose. This patent allows the pump heads to move up and down via the threaded block, activating the water pump. Water samples at different levels can be taken through the pump heads, enabling separate sampling of water at different levels and achieving multi-parameter sampling.

[0004] As shown in the above technology, the above patent only considers the influence of different depths. In fact, before a multi-parameter water quality analyzer can work, it is necessary to take out the water sample to be tested multiple times. These water samples should be uniformly mixed water samples. However, existing collection devices can only take multiple samples from the water body individually. The natural flow of the water body causes differences in each sample, which is not conducive to the comparison and analysis of experimental data in the later stage. In addition, existing water bodies often contain green algae or other suspended matter. These suspended particles will block and interfere with the normal operation of the sensor, affecting the accuracy of the subsequent water quality detection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a data acquisition device for a multi-parameter water quality analyzer. This solves the problem that existing data acquisition devices can only take multiple samples from the water body individually. The natural flow of the water body causes differences in each sample, which is not conducive to the comparison and analysis of subsequent experimental data. In addition, existing water bodies often contain green algae or other suspended solids. These suspended particles can block and interfere with the normal operation of the sensor, affecting the accuracy of subsequent water quality detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a data acquisition device for a multi-parameter water quality analyzer, comprising:

[0007] A base plate, wherein an anti-slip pad is provided on the bottom of the base plate;

[0008] A distribution component, the bottom of which is fixedly connected to the top of the base plate, is used to evenly distribute the treated water source.

[0009] A collection component, the bottom of which is fixedly connected to one side of the top of the base plate, is used to stably obtain equal amounts of water from multiple test tubes.

[0010] Preferably, the dispensing assembly includes a support base fixedly connected to the top of the base plate, a support shaft rotatably connected to the top of the support base, a bearing circular box fixedly connected to the top of the support shaft, a guide cone fixedly connected to the middle of the bottom of the inner wall of the bearing circular box, and a temporary storage tube connected to one side of the bottom of the bearing circular box.

[0011] Preferably, the top of the supporting circular box is connected to a water inlet pipe, the bottom of the inner wall of the water inlet pipe is fixedly connected to a limiting ring, the bottom of the limiting ring is movably connected to a filter cover, and the top of the filter cover is provided with an inclined rounded edge.

[0012] Preferably, the acquisition component includes a guide frame fixedly connected to the top of the base plate, a spring sheet fixedly connected to the top of the base plate, and a ball head fixedly connected to the top of the spring sheet.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides two technical solutions:

[0025] Example 1: A data acquisition device for a multi-parameter water quality analyzer, comprising:

[0026] Base plate 1, with an anti-slip pad installed on the bottom of base plate 1;

[0027] Distribution component 2, the bottom of distribution component 2 is fixedly connected to the top of base plate 1, and distribution component 2 is used to evenly distribute the water source.

[0028] The bottom of the collection component 3 is fixedly connected to one side of the top of the base plate 1. The collection component 3 is used to stably obtain equal amounts of water from multiple test tubes. With the setting of the distribution component 2, multiple identical water samples can be obtained at one time through the supporting round box 23 and the temporary storage tubes 25 evenly distributed at its bottom. This makes it convenient to use a water quality analyzer to perform multi-parameter testing on the same sample. The filter cover 28 can directly filter and remove solid suspended matter such as green algae, avoiding their blockage and interference with the sensor and ensuring the accuracy of the test results.

[0029] Example 2 differs from Example 1 in that: a multi-parameter water quality analyzer's data acquisition device includes a distribution component 2 comprising a support base 21 fixedly connected to the top of a base plate 1, a support shaft 22 rotatably connected to the top of the support base 21, a bearing circular box 23 fixedly connected to the top of the support shaft 22, a guide cone 24 fixedly connected to the middle of the bottom of the inner wall of the bearing circular box 23, a temporary storage tube 25 connected to one side of the bottom of the bearing circular box 23, the main body of the temporary storage tube 25 being an inclined tube, and an electrically controlled valve installed at each outlet of the temporary storage tube 25, an inlet pipe 26 connected to the top of the bearing circular box 23, a limit ring 27 fixedly connected to the bottom of the inner wall of the inlet pipe 26, a filter cover 28 movably connected to the bottom of the limit ring 27, and an inclined rounded edge on the top of the filter cover 28; the data acquisition component 3 includes a guide frame 31 fixedly connected to the top of the base plate 1, a spring piece 32 fixedly connected to the top of the base plate 1, a ball head 33 fixedly connected to the top of the spring piece 32, and the guide frame 31... The inner wall of the sample collection component 3 is movably connected to a support block 34. A sensing recess 35 is provided at the bottom of the support block 34. A placement frame 36 is movably connected to the inner wall of the support block 34. Friction textures are provided on the inner wall of the top of the support block 34 and on the surface of the placement frame 36. Limiting protrusions 37 are fixedly connected to the inner wall of the placement frame 36. Anti-slip grips 38 are fixedly connected to both sides of the surface of the placement frame 36. With the setting of the collection component 3, the support block 34 can slide in the guide frame 31 through the support block 34 and the test tube on its top, which facilitates the rapid movement of the test tube to the bottom of the temporary storage tube 25 to obtain water samples. The sensing recess 35 at the bottom of the support block 34, together with the spring 32 and the ball head 33, allows the staff to feel a slight vibration when it is moved to the receiving position, making it easy to move accurately. In addition, the placement frame 36 is used to wrap the test tube to avoid direct hand contact and handling, ensuring operational safety and sample accuracy.

[0030] Filtration typically uses filter membranes with pore sizes below 0.45 micrometers to remove suspended solids. Each support block 34 has a test tube slot at the top, and a sensing recess 35 is provided at the center of the bottom of each test tube slot.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the sample water is poured into the inlet pipe 26. After passing through the filter cover 28, the sample water enters the carrier round box 23, and then flows along the guide cone 24 into the temporary storage tube 25, ensuring that the temporary storage tube 25 is full. The test tube is inserted into the placement frame 36 using a test tube clamp, and the test tube is clamped and fixed by the limiting protrusion 37. The anti-slip grip 38 is used to insert the placement frame 36 into the inner wall of the carrier groove block 34, pushing the carrier groove block 34 against the surface of the guide frame 31. The spring 32 pushes the ball head 33 upward. When the ball head 33 is pushed in... In the sensing recess 35, due to the elasticity of the spring 32, the ball head 33 has a slight vibration when it impacts the inside of the sensing recess 35, which can be detected. At this time, it means that at least one test tube has entered the precise water receiving position. Open the valve of the temporary storage tube 25 and put the sample water inside into the test tube. When the filter cover 28 is dirty enough, pull up the filter cover 28 to detach it from the water inlet pipe 26. The bottom of the filter cover 28 separates from the top of the limiting ring 27. After cleaning and maintenance, replace it. When the device is completely finished, restore it.
