Description

Technical Field

[0001] The present invention relates to the field of semiconductor processing technology, and in particular to a device for detecting microorganisms in environmental samples and an operating method thereof. Background Art

[0002] As people pay more and more attention to the environment, environmental protection and governance have become an important part of sustainable development work. In order to monitor environmental changes in real time, safeguard public health, protect ecological balance, and evaluate the effectiveness of pollution control, we need to collect different environmental samples for microbial testing. When the existing microbial detection device is in use, the slide needs to be removed again after a single test of a sample, and then a new sample needs to be replaced for testing. When multiple samples need to be tested, the replacement process is cumbersome and the detection efficiency is low. In addition, the existing microbial detection device mainly clamps the slide by fixing it with a metal sheet, which can easily cause wear on the slide and affect the detection effect. At the same time, when the microbial detection device is out of use, the detection lens is prone to absorb dust, affecting subsequent use. Therefore, we need a microbial detection device and an operation method in environmental samples.

[0003] However, the currently used microbial detection devices require frequent replacement of sample slides when conducting multi-sample testing, and are unable to conduct continuous testing, protect sample slides, replace detection lenses, or protect detection lenses from dust. Summary of the invention

[0004] The object of the present invention is to provide a device and an operating method for detecting microorganisms in environmental samples to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A device for detecting microorganisms in environmental samples, comprising a support frame, a support plate is installed on the outer wall of the support frame, a rotating motor is installed on the bottom of the support plate, a rotating table is installed on the top of the rotating motor, a limit rod runs through the interior of the rotating table, a limit spring is installed on the outer wall of the limit rod, a splint is installed on the outer wall of the limit rod, a protective cover is installed on the outer wall of the splint, and anti-slip particles are provided on the outer wall of the protective cover, a detector is installed on the top of the support frame, a mirror seat is installed on the bottom of the detector, a reset spring is installed on the inner wall of the mirror seat, a clamping rod is installed on the outer wall of the reset spring, a lens is installed on the outer wall of the mirror seat, a fixing cover is installed on the outer wall of the support frame, a protective cover is installed on the outer wall of the fixing cover, a flocking protection ring is installed on the inner wall of the protective cover, a protective cotton sheet is installed on the inner wall of the flocking protection ring, and an LED irradiation lamp is installed on the bottom of the support frame.

[0007] Preferably, the limiting rods form a telescopic structure with the rotating table through limiting springs, and the limiting rods are distributed in a ring array with the central axis of the rotating table as the center.

[0008] Preferably, the splint is movably connected to the limiting rod, and the protective sleeve is sleeved on the splint.

[0009] Preferably, the clamping rod forms a telescopic structure with the mirror base through a return spring, and the clamping rod is symmetrically arranged with the central axis of the mirror base as the center.

[0010] Preferably, the side wall of the lens is of an open hole design, and the clamping rod is clamped and connected to the lens.

[0011] Preferably, the fixing sleeve is threadedly connected to the protective sleeve, and the protective cotton sheet is tightly fitted to the lens.

[0012] A device and operation method for detecting microorganisms in environmental samples, comprising the following steps:

[0013] S1. Connect the protective cover to the clamping plate, then pull the limit rod upwards, and then place the glass slide containing the sample on the rotating table. After adjusting the position, loosen the limit rod, and the limit rod is pressed downward by the elastic force of the limit spring to fix the glass slide;

[0014] S2. Turn on the LED irradiation lamp and the detector, adjust the slide to the appropriate position, perform microbial detection in the sample, and keep detection records simultaneously;

[0015] S3. After a single sample test is completed, the rotating motor is started to drive the rotating table to rotate, and the prepared next sample is continuously tested. At the same time, the sample slide after the test is completed is removed and replaced with a new sample slide for continuous testing;

[0016] S4. When the lens needs to be replaced according to different types of environmental samples, press the lever inward to remove the lens, then press the lever again, insert the new lens and lens holder into the specified position, and the lever is pushed out by the elastic force of the return spring and fixed with the new lens.

[0017] S5. After the final test is completed, the protective cover is threadedly connected to the fixed cover to protect the internal lens, prevent dust from entering the lens surface and affecting subsequent testing and use, and complete the microbial detection in the environmental sample.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The conventional microbial detection device can only detect a single sample by using a rotating motor and a rotating table. After the detection, the glass slide needs to be removed and replaced with a new detection sample, resulting in low detection efficiency. The rotating table in the present invention can replace three detection samples at a time. After a single sample is detected, the rotating table is driven by the rotating motor to rotate and the next sample is detected. At the same time, during the detection process, the sample that has been detected last time can be removed and replaced with a new detection sample. The setting of the rotating table can synchronize the process of detecting and replacing samples, thereby realizing continuous operation of sample detection and greatly improving detection efficiency in batch detection work.

[0020] 2. By adopting the limit rod, limit spring, splint, protective cover and anti-skid particles, the traditional microbial detection device is mainly used in use by lifting the elastic metal sheet and then fixing the glass slide. The frequent lifting and pressing actions will cause metal fatigue of the elastic metal sheet, resulting in reduced clamping ability. The glass slide is easy to loosen when fixed, thus affecting the detection effect. The splint of the present invention does not need to be lifted vertically frequently, and is mainly squeezed and fixed by the elastic force of the limit spring. The splint can be adjusted for horizontal displacement and can clamp and fix glass slides of different sizes. At the same time, the setting of the protective cover and anti-skid particles can prevent the glass slide from directly contacting the splint and causing surface scratches.

[0021] 3. The lens holder, reset spring, clamping rod and lens are arranged. By pressing the clamping rod, the clamping rod is extended inward and the lens is plugged into the lens holder. When the lens moves to the specified position, the clamping rod is pushed out by the elastic force of the reset spring and is engaged with the through hole on the side wall of the lens. The reset spring and the clamping rod are used in combination to facilitate the replacement of the lens.

[0022] 4. By using the fixed sleeve, protective sleeve, flocking protection ring and protective cotton sheet, when the microbial detection device is out of use, the protective sleeve is threadedly connected to the fixed sleeve to protect the lens and prevent external force from colliding with the lens. The flocking protection ring can increase the sealing of the connection between the fixed sleeve and the protective sleeve to prevent dust from entering. The protective cotton sheet can prevent the lens from contacting the protective sleeve to cause scratches, thereby increasing the service life of the lens. BRIEF DESCRIPTION OF THE DRAWINGS
