[0041] Example

[0042] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes

[0043] A device for detecting microplastics in water comprises: a mounting base 1; a microscope 2 arranged on the mounting base 1; a detection tube 3 arranged on the mounting base 1, the detection tube 3 having a water storage cavity 4, the water storage cavity 4 being used to place water to be detected, the detection tube 3 having a water inlet 8 and a water outlet, the water inlet 8 and the water outlet being both connected to the water storage cavity 4; a filter 5 arranged on the detection tube 3, located at the water outlet, the filter 5 being used to block debris in the water, and the microscope 2 being used to detect the debris.

[0044] In this embodiment, a microscope 2 is arranged on the mounting base 1, and a detection tube 3 is arranged on the mounting base 1. After water enters the water storage cavity 4 through the water inlet 8, the water passes through the filter 5 to block the debris in the water, and the water flows out from the water outlet. The microscope 2 takes a picture of the debris left on the filter 5, and the background program analyzes the debris components in the water. The detection efficiency is high, which reduces the need to transport the debris to the microscope 2 and avoids the problem of impurities in the air entering the debris during transportation.

[0045] Furthermore, the filter element 5 includes: a mounting chamber 6 disposed on the detection tube 3 and located at the water outlet; and a gauze 7 disposed in the mounting chamber 6, the gauze 7 being used to block debris in the water.

[0046] In this embodiment, the filter element 5 includes an installation bin 6 and a gauze 7. Since the gauze 7 may be damaged after long-term filtration, the gauze 7 and the installation bin 6 of this solution are configured as a split structure. When the gauze 7 is seriously damaged, the gauze 7 can be removed and replaced separately, thereby reducing the use cost of the device.

[0047] Furthermore, it also includes: a water outlet pipe 9 arranged on the filter element 5.

[0048] In this embodiment, the water outlet pipe 9 is arranged on the installation chamber 6 of the filter element 5. The water entering from the water inlet 8 is connected with the water outlet and the water outlet pipe 9 through the water outlet to form a circulation, and the debris in the circulating water is blocked on the gauze 7 by the gauze 7. The microscope 2 is used to take pictures, and the background analyzes the composition of the debris, thereby avoiding the process of transporting the debris, improving the convenience of detection, and increasing the efficiency of detection.

[0049] Furthermore, it also includes: a rotating seat 22 rotatably arranged on the installation chamber 6, and a screen 7 is arranged on the rotating seat 22; a driving unit 24 arranged on the installation chamber 6, and the driving unit 24 is used to drive the rotating seat 22 to rotate, and after the rotating seat 22 rotates, it blocks or does not block debris in the water.

[0050] In this embodiment, the rotating seat 22 is arranged in the installation bin 6. After the first batch of water quality is tested, the rotating seat 22 is driven to rotate by the driving unit 24. After the gauze 7 rotates with the rotating seat 22, the second batch of water quality enters the water storage cavity 4 through the water inlet 8 and flows out from the water outlet. During the outflow process, the remaining debris on the gauze 7 will be washed away, thereby avoiding errors in the detection of the second batch of water quality due to the debris on the gauze 7 during the first detection.

[0051] Furthermore, it also includes: two quick-change clamps 10, both of which are arranged on the installation bin 6, one quick-change clamp 10 is used to connect the installation bin 6 and the detection tube 3, and the other quick-change clamp 10 is used to connect the installation bin 6 and the water outlet pipe 9.

[0052] In this embodiment, a quick-change clamp 10 connects the installation bin 6 and the detection tube 3, and another quick-change clamp 10 connects the installation bin 6 and the water outlet pipe 9. The quick-change clamp 10 can quickly remove the installation bin 6, making it more convenient to replace and remove the rotating parts and the gauze 7 inside the installation bin 6.

[0053] Furthermore, the mounting base 1 has a detection cavity 20 and a detection hole 21, the detection hole 21 connects the detection cavity 20 and the water storage cavity 4, the microscope 2 is arranged in the detection cavity 20, and also includes: a fill light 11 arranged in the mounting base 1, the fill light 11 is used to provide fill light to the microscope 2; a glass cover plate 12 arranged on the mounting base 1, the glass cover plate 12 is located at the detection hole 21, and there are multiple fill lights 11, which are arranged around the microscope 2 at circumferential intervals.

[0054] In this embodiment, the mounting base 1 has an air detection and detection hole 21, and a glass cover plate 12 is sealed on the detection hole 21. When the microscope 2 is working, the sundries on the gauze 7 can be photographed and analyzed through the glass cover plate 12, and the water in the water storage cavity 4 is prevented from flowing into the detection cavity 20, thereby preventing the microscope 2 from being damaged by moisture. The fill light 11 is used to provide fill light to the microscope 2, thereby improving the clarity of the sundries photographed by the microscope 2.

[0055] Furthermore, the detection tube 3 has an overflow port 13 , and the overflow port 13 is used to flow out the excess water in the water storage cavity 4 .

[0056] In this embodiment, the height of the overflow port 13 is higher than the height of the water inlet 8, thereby further preventing the water in the water storage cavity 4 from flowing into the detection cavity 20. When the water level in the water storage cavity 4 reaches the specified position, it is discharged from the overflow port 13, further protecting the microscope 2 and the fill light 11 from damage.

[0057] Furthermore, it also includes: a fixing member 14 arranged on the mounting base 1, which is used to fix the microscope 2 and the mounting base 1.

[0058] In this embodiment, in order to prevent the microscope 2 from falling off during use, the present solution further provides a fixing member 14, which is disposed on the mounting base 1 to fix the microscope 2 and the mounting base 1 to prevent the microscope 2 from falling off from the fixing base.

[0059] Furthermore, the quick-change clamp 10 includes: a first rotating ring 15 mounted on the mounting chamber 6; a second rotating ring 16 hingedly arranged on the first rotating ring 15, after the second rotating ring 16 rotates, the first rotating ring 15 and the second rotating ring 16 are wrapped around the mounting chamber 6, and the second rotating ring 16 has a butt end 17; a clamping member 18 hingedly arranged on the first rotating ring 15, the clamping member 18 has a clamping end 19, after the clamping member 18 swings, the clamping end 19 abuts against the butt end 17.

[0060] In this embodiment, the first rotating ring 15 is sleeved on the installation bin 6, and the second rotating ring 16 is hingedly arranged on the first rotating ring 15. The first rotating ring 15 and the second rotating ring 16 form a closed shape. The second rotating ring 16 has a butt end 17, and the clamping piece 18 is arranged on the first rotating ring 15. After the clamping piece 18 swings, the clamping piece 18 and the clamping end 19 are clamped to complete the clamping of the first rotating ring 15 and the second rotating ring 16, thereby realizing quick disassembly and assembly, increasing the efficiency of replacing the gauze 7, and realizing the separability of the overall structure. When the equipment is partially damaged, the corresponding part can be replaced separately, reducing the use cost and maintenance cost.

[0061] Furthermore, the microscope 2 and the gauze 7 are concentrically arranged.

[0062] In this embodiment, the microscope 2 and the gauze 7 are concentrically arranged, which increases the detection range of the microscope 2 for debris on the gauze 7.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
