Description

TECHNICAL FIELD

[0001] The utility model relates to the field of microorganism sampling, and particularly relates to a microorganism sampling device. BACKGROUND

[0002] In the field of microorganism sampling technology, accurate, stable and efficient sampling operation is the cornerstone for obtaining scientific and reliable microorganism detection data, and it is of great importance to the research and practice in many fields such as environmental monitoring, medical and health care, food and drug safety. However, the current widely used traditional microorganism sampling equipment exposes a series of key problems that need to be solved in the actual operation process.

[0003] Firstly, in terms of installation method, the traditional microorganism sampling hanger usually adopts bolt fastening or hook suspension. Among them, the bolt fastening method needs to drill holes on the bearing structure during implementation, which not only consumes time and labor cost, but also causes irreversible damage to the integrity of the bearing structure, which is contrary to the strict requirements of places such as sterile wards of medical institutions, clean production areas of biological pharmaceutical enterprises, and other places with strict requirements on environmental cleanliness and structural integrity. The hook suspension method is severely dependent on the spatial layout and quantity of the suspension points, and its flexibility and adaptability are severely limited when facing complex and variable building structures or spatial layouts, making it difficult to quickly and accurately determine the optimal installation position in a limited space.

[0004] Secondly, in terms of stability, the traditional microorganism sampling device shows significant vulnerability in the actual sampling environment. Microorganism sampling is usually carried out in areas with dense personnel flow and complex aerodynamic environment, such as scientific research laboratories, public activity places, industrial production workshops, etc. The traditional sampling support often only has a simple mechanical support structure, which is difficult to effectively resist external interference factors such as slight air flow disturbance and ground vibration. Once the sampling device shakes, the microorganism samples in the culture dish will inevitably be physically disturbed, which will lead to deviation of the sampling results and failure to accurately map the real distribution and community structure of microorganisms in the environment.

[0005] In terms of height adjustment, the existing sampling equipment generally has the problem of insufficient precision and convenience in height adjustment mechanism. Most devices rely on simple linear scales or subjective experience of operators to adjust the height, which is difficult to meet the strict and accurate requirements of sampling height in different sampling environments. Different application scenarios, such as sampling of specific microorganisms in biological safety laboratories, hygiene monitoring in food processing workshops, etc., all have clear standards for sampling height. The inaccuracy of height adjustment may lead to lack of representativeness of the collected microorganism samples, which will have a chain of negative effects on subsequent key links such as microorganism culture, identification and analysis.

[0006] In addition, the traditional sampling support has obvious short board in space utilization efficiency. The structure design often fails to fully consider space optimization, resulting in large equipment size and excessive space occupation. In places where space resources are scarce, the traditional sampling support not only brings inconvenience to sampling operation, but also may conflict with other equipment or work processes in space, reducing the overall work efficiency.

[0007] In summary, the traditional microorganism sampling technology has significant defects in the core indicators of installation convenience, stability, high adjustment precision, and space utilization efficiency, which seriously restricts the improvement of the quality and efficiency of microorganism sampling work. Under this background, it has become an urgent task for the development of the industry to develop an innovative and breakthrough microorganism sampling device to meet the diversified and high-precision needs of modern microorganism sampling work.

[0030] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0031] Embodiment One:

[0032] The utility model discloses a kind of microbial sampling devices as shown in Figure 1 Most of the roof of factory building is iron or can adhere to iron area, so the application adopts the mode of magnet adsorption to fix the sampling device. The device includes a magnet assembly located at the top of the device and a support seat 8 connected below the magnet assembly by a pull rope 3. The magnet assembly includes a magnet 1 and a mounting ring 2, the magnet 1 is embedded in the upper surface of the mounting ring 2 and is higher than the surface height of the mounting ring 2, a ring groove is provided around the magnet 1 on the upper surface of the mounting ring 2, which is used to hold the magnetic powder that falls off due to wear of the magnet 1, preventing the magnetic powder from falling into the culture dish below. The upper end of the pull rope 3 is connected to the mounting ring 2, and the lower end is wound around the surface of the adjusting screw 4. The adjusting screw 4 is installed horizontally by threads on the side of the support seat 8. The surface of the pull rope 3 has clear scale lines. By turning the adjusting screw 4, the adjusting screw is rotated into or out of the support seat 8, the pull rope 3 is wound or unfolded, and the length of the part of the pull rope 3 between the mounting ring 2 and the support seat 8 is changed, thereby changing the height of the support seat 8. The pull rope 3 and the corresponding adjusting screw 4 are two or three groups, which are symmetric or evenly distributed about the center of the support seat 8. The support seat 8 is a rotary body structure with a U-shaped cross-section. The height and thickness of the U-shaped edge are determined according to the limiting requirements of the culture dish 9. To facilitate the placement of the culture dish 9 in the center of the support seat 8, a plurality of concentric circular marks are provided on the placement surface of the support seat 8. The cross-section of the concentric circular marks is a V-shaped groove. To ensure that the culture dish is installed firmly without slipping or deviating, three set screws 5 are provided on the side wall of the support seat 8. The three set screws 5 are evenly distributed in a circular pattern with the center of the support seat 8 as the center. The set screws 5 and the adjusting screws 4 are arranged at intervals on the side of the support seat 8.

[0033] The bottom of the support base 8 has a mounting slot 8-1 for fixing the range finder 7. The range finder 7 is vertically installed at the center of the bottom of the support base 8 and can be removed along the slot direction after use. The support base 8 is fixed with a level 6 on the side surface. The level 6 is used to check whether the support base 8 is in a horizontal position. The adjusting screw 4 can accurately adjust the height of the support base 8 from the ground according to the range finder 7 at the bottom of the support base 8. The range finder is preferably a laser range finder.

[0034] After the installation and positioning of the sampling device are completed, the length of the pull rope 3 is adjusted according to the actual height of the ceiling. The length of the pull rope is adjusted by the adjusting screw 4, so that the pull rope is elongated to an appropriate length. The height position of the support base 8 is accurately adjusted according to the digital display on the range finder 7, so as to ensure that the support base 8 is in the specified height position. After the height position is adjusted, the range finder 7 is removed along the slot direction. The culture dish 9 is placed in the support base 8, so that the bottom edge of the culture dish 9 is tightly fitted with the V-shaped groove, and the culture dish 9 is effectively limited by the set screw 5.

[0035] The pull rope 3 is made of hard steel wire rope or carbon fiber rope. During sampling, due to the self-weight of the support base 8 and the rigidity of the pull rope itself, it can effectively resist strong airflow interference caused by personnel walking, equipment moving, etc. The sampling time can be determined according to the specific sampling purpose and the type of microorganisms. After sampling is completed, the culture dish 9 is taken out of the support base 8, and then the adjusting screw 4 is adjusted in the reverse direction, and the device is taken off from the ceiling. After being taken off, the device should be cleaned and checked comprehensively to check whether the adsorption force of the magnet 1 is normal, whether the pull rope 3 is worn, whether the support base 8 is dirty or damaged, etc. Timely repair or replacement can ensure normal use in the next sampling operation.

[0036] In summary, the microorganism hanging bracket can fix the culture dish 9 through the cooperation between the magnet 1, the pull rope 3 and the support base 8, and can adjust the length of the device through the range finder 7 to adapt to the use of the height of the culture dish from the ground in different room ceilings. After use, it can be directly taken down. The level 6 can increase the self-weight of the device, thereby improving the stability of the device.

[0037] Example Two

[0038] As shown in Figures 2-3 In this embodiment, the pull rope 3 and the adjusting screw 4 are replaced by a combination structure of an upper pull rod 10, an adjusting screw sleeve 11 and a lower pull rod 12. The other structures are the same as those in Example One. The upper pull rod 10 is connected with the mounting ring 2, and the lower pull rod 12 is connected with the support base 8. The two pull rods are processed with threads in completely opposite directions. The two ends of the adjusting screw sleeve 11 are respectively processed with threads in completely opposite directions. The two pull rods are correspondingly installed at the two ends of the adjusting screw sleeve 11. By rotating the adjusting screw sleeve 11, the two pull rods are driven to move relatively or oppositely, so as to adjust the distance between the mounting ring 2 and the support base 8.

[0039] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. The present application can be modified and changed in various manners by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
