[0002] Water quality testing involves testing water samples and then further subdividing the testing methods into physical, chemical, and biological aspects.

[0003] When testing water quality, there are generally two methods: benchtop testing and portable testing. Portable testing devices are limited in size and can only test a limited number of subcategories. They typically use a light wave emitting module to emit specific light waves that pass through a sampling dish. The suspended matter in the water sample inside the dish disperses the light waves, and the light wave receiving module uses the different wavelengths of light received to determine the content of impurities in the water sample.

[0004] Among the findings, it was discovered that existing detection devices require the water sample and detection reagent to be shaken thoroughly before use. This issue needs further refinement and improvement to increase the device's speed and simplify the work for outdoor personnel. Secondly, when using the detector, the light wave emitting module and the wave receiving module are affected by floating dust, which in turn affects the detection accuracy of the entire device. Based on this issue, the structure of the detection device needs to be adjusted to solve the above problems. Utility Model Content

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.

[0020] In this utility model:

[0021] Reference Figure 1-4 A portable environmental detector includes a detector body 1, which is composed of a battery compartment 102 and a detection compartment 103. A control panel 101 is provided above the battery compartment 102. A light wave receiving module 7 is fixedly installed on one side inside the detection compartment 103. A main cover plate 2 is installed on the detection compartment 103 via a rotating shaft. A secondary cover plate 201 is installed on one side of the main cover plate 2 via a rotating shaft.

[0022] A light wave emitting module 6 is fixedly installed on one side of the inner side of the sub-cover plate 201;

[0023] A slide rail 3 is fixedly installed inside the main cover plate 2. A rack 302 is installed on one side of the slide rail 3. A slider 301 is movably connected inside the slide rail 3. A support 5 is rotatably connected above the slider 301 via a rotating shaft. A first gear 501 is fixedly installed on the outer ring of the rotating shaft of the support 5. A second gear 502 is rotatably connected to the bottom of the support 5. Clamping plates 503 are fixedly installed on both sides above the support 5. A sampling dish 4 is movably installed above the support 5.

[0024] The clamping plate 503 is made of shape memory metal. There are pressing blocks on both sides of the upper part of the clamping plate 503. There are recesses on both sides of the sampling dish 4. The recesses on the sampling dish 4 fit with the pressing blocks on the clamping plate 503. The pressing blocks on the clamping plate 503 can be used to clamp the sampling dish 4 to facilitate the fixation of the sampling dish 4.

[0025] A side plate 104 is movably connected to one side of the detection chamber 103. The side plate 104 is fixedly connected to the slider 301. The slider 301 can be pulled out using the side plate 104. The first gear 501, the second gear 502 and the rack 302 mesh with each other. During the movement of the slider 301, the second gear 502 meshes with the rack 302, which in turn drives the first gear 501 to rotate the support 5. At this time, the sampling dish 4 is rotated, which shakes the water sample and detection reagent inside the sampling dish 4 to achieve the auxiliary purpose.

[0026] Furthermore, the sampling dish 4 is located between the light wave emitting module 6 and the light wave receiving module 7. The light wave emitting module 6 emits specific light waves that pass through the sampling dish 4. The suspended matter in the water sample inside the sampling dish 4 will disperse the light waves. The light wave receiving module 7 uses the received light waves of different wavelengths to determine the content of impurities in the water sample.

[0027] Furthermore, sealing strips are provided at the connection points of the detector body 1, main cover plate 2, and secondary cover plate 201; a buckle is provided at the connection point between the detection chamber 103 and the main cover plate 2, and a buckle is provided at the connection point between the main cover plate 2 and the secondary cover plate 201. Using the pivot, the main cover plate 2 can be opened to clean the light wave receiving module 7. Similarly, using the secondary cover plate 201, the light wave emitting module 6 can be flipped out to clean it.

[0028] Furthermore, the light wave transmitting module 6 and the light wave receiving module 7 are electrically connected to the battery compartment 102 via the control panel 101.

[0029] Working principle: First, water samples are taken and placed in sampling dish 4. Then, a detection reagent is added to sampling dish 4. At this time, the side plate 104 is pulled out. The indentation on the sampling dish 4 then engages with the squeezing block on the clamping plate 503. The squeezing block on the clamping plate 503 can clamp the sampling dish 4 for easy fixation. Next, the side plate 104 is pushed in, and the first gear 501, the second gear 502, and the rack 302 mesh. During the movement of the slider 301, the second gear 502 meshes with the rack 302, which in turn drives the first gear 501 to rotate the support 5. This causes the sampling dish 4 to rotate, and the water inside the sampling dish 4 is sampled. The sample and detection reagent are shaken well and repeated. Then, the sampling dish 4 is placed between the light wave emitting module 6 and the light wave receiving module 7. The light wave emitting module 6 emits specific light waves that pass through the sampling dish 4. The suspended matter in the water sample inside the sampling dish 4 will disperse the light waves. The light wave receiving module 7 uses the received light waves of different wavelengths to determine the content of impurities in the water sample and displays it on the control panel 101. Finally, when it is necessary to clean the light wave emitting module 6 and the light wave receiving module 7, the main cover plate 2 can be opened using the pivot to clean the light wave receiving module 7. Similarly, the light wave emitting module 6 can be flipped out using the secondary cover plate 201 for cleaning.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
