Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, specifically relating to a rapid detection device for microorganisms in water. Background Technology

[0002] There are many types of bacteria in water, so it is necessary to test the microorganisms in the water regularly. The quality of the water is then assessed by the number of different types of microorganisms. During the testing process, the treated water sample needs to be mixed with agar culture medium. Agar acts as a coagulant, which allows the liquid culture medium to form a stable solid surface after cooling. This solid matrix can disperse and fix the bacteria in the water sample in a specific location, allowing them to form independent colonies during the culture process.

[0003] However, the existing mixing method involves manual shaking, which is time-consuming and labor-intensive, and the mixing is not thorough. Furthermore, the testing instruments are not easy to move and adjust, and it is not easy to make rapid contact with the sample, which affects the efficiency of water quality testing. Utility Model Content

[0004] To overcome the problems of existing methods where mixing involves manual shaking, which is time-consuming, labor-intensive, and results in insufficient mixing; and the difficulty in moving and adjusting the testing instrument, hindering rapid contact with the sample and affecting the efficiency of water quality testing, this invention provides a rapid water quality microbial detection device. The drive mechanism rotates the shaft and support platform, ensuring thorough mixing of the water sample and agar culture medium, saving manpower and time, guaranteeing consistent mixing quality each time, and providing a good foundation for subsequent bacterial culture. The height adjustment mechanism adjusts the height of the microscope, enabling it to accurately focus on the sample in the culture dish, improving the accuracy and precision of the detection. The limiting and locking component firmly fixes the culture dish to the support platform, preventing shaking or displacement during rotation, and also facilitating quick replacement of culture dishes by operators. The microscope allows for magnified observation of microorganisms in the culture dish, enabling testing personnel to accurately identify and count the types and quantities of microorganisms, thereby assessing the water quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A rapid detection device for water microorganisms mainly includes a base, a connecting frame, a height adjustment mechanism, a microscope, a support frame, a rotating shaft, a drive mechanism, a support platform, a limiting and clamping assembly, and a culture dish. The connecting frame is installed at the top of the base, the height adjustment mechanism is installed at the end of the connecting frame, the microscope is installed on the height adjustment mechanism, and the support frame is fixedly installed on the upper surface of the base. The support frame includes a fixing ring and upright plates. The fixing ring is installed at the top of the base, and four upright plates are installed on the fixing ring at equal intervals around their circumferences. A circular opening is formed at the central connection of the four upright plates. The cylindrical through-slot allows the rotating shaft to be rotatably installed within it. A mounting slot is provided at the bottom of the upright plate, and the drive mechanism is mounted on this slot. The drive mechanism includes a driving gear, a driven gear, and a micro motor. The driving gear and driven gear are rotatably installed within the mounting slot. The driven gear is connected to the rotating shaft. The micro motor is mounted at the top of the upright plate and is connected to the driving gear via a transmission connection. The driving gear and driven gear are meshed with each other. A support platform is mounted at the top of the rotating shaft, and a limiting and clamping assembly is mounted on the support platform. The culture dish is clamped inside the limiting and clamping assembly, located directly below the microscope. A culture dish lid is provided at the top of the culture dish.

[0006] The height adjustment mechanism includes a slide rail, a slider, a locking bolt, a connecting block, and an L-shaped connecting plate. The slide rail is installed on the top of the connecting frame, the slider is slidably installed on the slide rail, the locking bolt passes through the end of the slide rail to fix the slider on the slide rail, the connecting block is installed on the end of the slider, the L-shaped connecting plate is connected to the connecting block, and the microscope is installed on the L-shaped connecting plate.

[0007] The limiting and clamping assembly includes an annular base and locking knobs. The annular base is installed on the top of the support platform, and the locking knobs are installed on the annular base at equal intervals around its circumference. There are four locking knobs.

[0008] The locking knob has a silicone buffer layer on its inner side.

[0009] The microscope has a ring-shaped LED illumination source at the front end of the objective lens.

[0010] The beneficial effects of this utility model are:

[0011] The drive mechanism rotates the shaft and support platform, ensuring thorough mixing of the water sample and agar culture medium. This saves manpower and time, guarantees consistent mixing quality, and provides a good foundation for subsequent bacterial culture. The thoroughly mixed culture medium disperses bacteria more evenly, allowing each bacterium to have a relatively independent growth space on the solid substrate. This facilitates accurate counting and identification of different bacterial species, thereby improving the accuracy of water quality assessment. The height adjustment mechanism allows for convenient adjustment of the microscope's height, enabling accurate focusing on the sample in the culture dish and enhancing detection accuracy and precision. The limiting and locking assembly firmly fixes the culture dish to the support platform, preventing shaking or displacement during rotation and facilitating quick dish replacement by operators. The microscope provides magnified observation of microorganisms in the culture dish, enabling accurate identification and counting of microbial species and quantities, thus assessing water quality.

[0017] This utility model discloses a rapid detection device for microorganisms in water quality. The device mainly includes a base 1, a connecting frame 2, a height adjustment mechanism 3, a microscope 4, a support frame 5, a rotating shaft 6, a drive mechanism 7, a support platform 8, a limiting and clamping assembly 9, and a petri dish 10. The connecting frame 2 is installed at the top of the base 1, the height adjustment mechanism 3 is installed at the end of the connecting frame 2, the microscope 4 is installed on the height adjustment mechanism 3, and the support frame 5 is fixedly installed on the upper surface of the base 1. The support frame 5 includes a fixing ring 51 and four upright plates 52. The fixing ring 51 is installed at the top of the base 1, and four upright plates 52 are circumferentially and equally spaced on the fixing ring 51. A cylindrical through groove 521 is formed at the central connection of the four upright plates 52. The rotating shaft 6 is rotatable. The drive mechanism 7 is installed in the cylindrical through groove 521. The bottom end of the upright plate 52 has an installation groove 522. The drive mechanism 7 includes a drive gear 71, a driven gear 72, and a micro motor 73. The drive gear 71 and the driven gear 72 are rotatably installed in the installation groove 522. The driven gear 72 is connected to the rotating shaft 6. The micro motor 73 is installed at the top of the upright plate 52 and is connected to the drive gear 71. The drive gear 71 and the driven gear 72 are meshed with each other. The support platform 8 is installed at the top of the rotating shaft 6. The limiting and clamping assembly 9 is installed on the support platform 8. The culture dish 10 is clamped inside the limiting and clamping assembly 9 and is located directly below the microscope 4. The top of the culture dish 10 is provided with a culture dish cover 101.

[0018] like Figure 2 , Figure 3 , Figure 4 As shown, the height adjustment mechanism 3 includes a slide rail 31, a slider 32, a locking bolt 33, a connecting block 34, and an L-shaped connecting plate 35. The slide rail 31 is installed at the top of the connecting frame 2. The slider 32 is slidably installed on the slide rail 31. The locking bolt 33 passes through the end of the slide rail 31 to fix the slider 32 on the slide rail 31. The connecting block 34 is installed at the end of the slider 32. The L-shaped connecting plate 35 is connected to the connecting block 34. The microscope 4 is installed on the L-shaped connecting plate 35. According to the height of the petri dish 10 and the actual observation requirements, the height adjustment mechanism 3 is adjusted. Specifically, the locking bolt 33 is loosened to allow the slider 32 to slide on the slide rail 31, which drives the connecting block 34 and the L-shaped connecting plate 35 to move, thereby adjusting the height of the microscope 4 installed on the L-shaped connecting plate 35. When the height is adjusted appropriately, the locking bolt 33 is tightened to fix the slider 32 on the slide rail 31.

[0019] like Figure 2 , Figure 4As shown, the limiting and clamping assembly 9 includes an annular base 91 and locking knobs 92. The annular base 91 is installed on the top of the support platform 8, and the locking knobs 92 are installed on the annular base 91 at equal intervals around its circumference. There are four locking knobs 92. The inner side of the locking knobs 92 is provided with a silicone buffer layer. By rotating the four locking knobs 92, the culture dish 10 is limited inside the annular base 91.

[0020] like Figure 3 As shown, the objective lens of the microscope 4 is provided with a ring-shaped LED illumination source 41; the LED illumination source 41 provides sufficient and uniform illumination for observation, improving the clarity of observation.

[0021] Work process:

[0022] The water sample to be tested is treated as necessary. Then, the treated water sample and agar culture medium are injected into the culture dish 10 in a certain ratio. The culture dish lid 101 is closed, and the four locking knobs 92 of the limiting clamping component 9 are opened. The culture dish 10 is placed into the annular seat 91, and the locking knobs 92 are tightened. The silicone buffer layer provides flexible clamping to prevent the culture dish from breaking. The drive mechanism 7 is started, and the micro motor 73 drives the drive gear 71 to rotate. Through meshing transmission, the driven gear 72 and the rotating shaft 6 are driven to rotate. The rotating shaft 6 drives the support platform 8 and the culture dish 10 to rotate at a uniform speed, so that the water sample and agar are fully mixed and the microorganisms are evenly dispersed. This replaces manual shaking and improves the mixing efficiency. After uniform mixing... Turn off the micro motor 73, loosen the locking bolt 33 on the slide rail 31, manually slide the slider 32 to move the L-shaped connecting plate 35 and the microscope 4 up and down, adjust to a height where the image on the surface of the petri dish 10 is clear, and fix the slider position with the locking bolt 33 to ensure the stability of the microscope 4. The LED illumination source 41 provides uniform illumination to enhance the clarity of observation. After the petri dish 10 is left to stand, the agar solidifies to form a solid culture medium, and the dispersed microorganisms are fixed in a specific position. Observe the colony formation through the microscope 4, record data such as the number and morphology of colonies, and assess the water quality. After the test is completed, turn off the LED illumination source 41, loosen the locking knob 92 and take out the petri dish to complete the test process.
