Description

Technical Field

[0001] This utility model relates to the field of microbial sampler technology, and in particular to a microbial sampler for environmental monitoring. Background Technology

[0002] An environmental microbial sampler is a device specifically designed to collect and analyze samples of microorganisms in the air, used to detect the concentration of microorganisms in the air.

[0003] The specific working principle of the microbial sampler for environmental monitoring is to use the principle of aerodynamics to draw in air by using the negative pressure generated by the vacuum pump. The drawn-in air enters and impacts the sampling plate in the sampler. The sampling plate is pre-filled with agar medium, and the microbial particles in the air are sampled and captured on the sample plate containing the agar medium.

[0004] Currently, most existing environmental microbial samplers do not have a sealed structure in their sampling tubes after sampling. This allows external dust particles to naturally enter the sampler through the sampling tube, contaminating the microbial particle samples collected on the sampling plate and affecting the results of subsequent environmental air microbial sampling.

[0005] Moreover, the sampling plates of most existing environmental microbial samplers are inconvenient to remove from the sampler.

[0006] In addition, it is necessary to sample airborne microorganisms in different outdoor areas. However, most of the existing environmental microbial samplers are not convenient to move flexibly outdoors, which greatly reduces the mobility of environmental microbial samplers for outdoor sampling. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a microbial sampler for environmental monitoring.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Design a microbial sampler for environmental monitoring, including a sampling platform, a sampler and a cylinder on the sampling platform, a sealing groove inside the sampler, a sampling plate inserted in the sealing groove, a top frame on the cylinder, a cover on the top frame, a sealing ring on the cover, a sampling tube on the sampler, ribs and a fine mesh plate on the sampling tube, and legs and a handle on the sampling platform;

[0010] The sampling plate is provided with a fixing block and a hook groove. The fixing block is provided with a screw pin and a pin handle. The sampling plate is provided with a sampling medium.

[0011] The outrigger is provided with casters and a bottom plate. The bottom plate is provided with a storage battery and a vacuum pump. The vacuum pump is connected with an exhaust pipe and a suction pipe. The exhaust pipe is provided with a dust-proof pipe.

[0012] Further, there are two symmetrically arranged cylinders on the left and right, and the top frame is integrally in a "U" - shaped structure.

[0013] Further, the lower end of the cover is in a circular - shaped opening structure, and the sealing ring is evenly laid along the inner wall surface of the cover.

[0014] Further, the front end of the sealing groove is open and is matched with a sampling plate in a rectangular - shaped structure for extrusion and insertion.

[0015] Further, the dust - proof pipe is arranged at the right - hand end of the exhaust pipe, and the inner cavity of the dust - proof pipe is communicated with the inner cavity of the exhaust pipe.

[0016] Further, the top end of the sampling pipe is open, and a flow - guiding surface is arranged on the inner cavity wall of the top - end opening of the sampling pipe.

[0017] Further, the screw pin passes through the fixing block and is threadedly connected with the sampler. The handle of the pin is integrally in a rhombus - shaped structure. The hook groove is a semi - circular arc - shaped groove and is opened at the lower end of the sampling plate. The inner groove wall of the hook groove is provided with an anti - slip layer.

[0018] A microbial sampler for environmental detection proposed by the present utility model has the following beneficial effects:

[0019] 1. By setting a vertical electric - control type cover structure on the sampling table, a sealing ring structure on the cover, and a dust - proof pipe on the exhaust pipe of the vacuum pump in the present utility model, after the sampling is completed, the top - end opening of the sampler can be stably, effectively and comprehensively squeezed and covered for sealing, avoiding external dust particles from naturally entering the sampler through the sampling pipe, thereby effectively avoiding contamination of the microbial particle samples collected on the sampling plate and ensuring the results of microbial sampling for environmental air detection in the later stage.

[0020] 2. By setting a sealing groove in the sampler, a fixing block with a screw pin and a hook groove on the sampling plate, and then setting a handle of the pin in a rhombus - shaped structure on the screw pin in the present utility model, the sampling plate can be conveniently taken out from the sampler, improving the convenience of taking out the sampling plate from the sampler.

[0021] 3. By setting a handle and an outrigger structure with casters on the sampling table in the present utility model, the overall sampling table can be conveniently pushed in four directions, improving the moving flexibility of the overall microbial sampler for environmental detection during sampling outdoors.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-5 A microbial sampler for environmental monitoring includes a sampling platform 1, a sampler 4 and a cylinder 7 on the sampling platform 1, a sealing groove 41 is provided in the sampler 4, a sampling plate 5 is inserted in the sealing groove 41, a top frame 71 is provided on the cylinder 7, a cover 8 is provided on the top frame 71, a sealing ring 81 is provided on the cover 8, a sampling tube 6 is provided on the sampler 4, a rib plate 61 and a fine mesh plate 62 are provided on the sampling tube 6, and a support leg 12 and a handle 11 are provided on the sampling platform 1.

[0030] The sampling plate 5 is provided with a fixing block 52 and a hook groove 55. The fixing block 52 is provided with a screw pin 53, the screw pin 53 is provided with a pin handle 54, and the sampling plate 5 is provided with a sampling medium 51.

[0031] The outrigger 12 is equipped with casters 13 and a base plate 2. The base plate 2 is equipped with a battery 21 and a vacuum pump 3. The vacuum pump 3 is connected to an exhaust pipe 31 and an air extraction pipe 33. The exhaust pipe 31 is equipped with a dustproof pipe 32. The battery 21 can supply power to the corresponding electrical equipment.

[0032] The caster wheel 13 is a universal braking wheel.

[0033] The rib plate 61 is made of hard alloy steel, which improves the structural stability between the sampling tube 6 and the sampler 4.

[0034] Some of the structures described in this patent are common structures of the microbial sampler for environmental detection, which are prior art. Some of the prior art structures are not drawn and labeled, so there is no need to elaborate. Among them, the sampling medium 51 is the agar medium.

[0035] There are two cylinders 7 that are symmetric left and right. The top frame 71 is in an overall "U" - shaped structure. The two cylinders 7 improve the stable and accurate covering of the cover 8 on the sampling tube 6.

[0036] The lower end of the cover 8 is a circular - shaped opening structure. The sealing ring 81 is evenly laid along the inner wall surface of the cover 8. The sealing ring 81 is made of EPDM (ethylene - propylene - diene monomer) rubber material, which has excellent high - elastic sealing performance and can be extrusion - sleeved with the outer wall surface of the sampling tube 6 to achieve the sealing and waterproof effect.

[0037] The front end of the sealing groove 41 is open and is extrusion - inserted and matched with the sampling plate 5 of rectangular structure. The inner groove wall of the sealing groove 41 has a high - elastic polyurethane sealing pad, which can form an extrusion - sealing and waterproof effect with the side wall of the inserted sampling plate 5.

[0038] The dust - proof pipe 32 is arranged at the right - hand end of the exhaust pipe 31. The inner cavity of the dust - proof pipe 32 is connected to the inner cavity of the exhaust pipe 31. The dust - proof pipe 32 is filled with a nylon melt - blown filter element filling layer, which ensures the air - flow effect and has the waterproof and dust - proof effects at the same time.

[0039] The top end of the sampling tube 6 is open. A flow - guiding surface 63 is provided on the inner cavity wall of the top - end opening of the sampling tube 6. When sucking air samples, the sucked air samples will quickly gather at the fine - pore mesh plate 62 part along the flow - guiding surface 63, and then the air samples as a whole will vertically pass downward through the fine - pore mesh plate 62, which improves the sucking and gathering efficiency of the air samples.

[0040] The screw pin 53 passes through the fixing block 52 and is thread - connected to the sampler 4. The pin handle 54 is in an overall diamond - shaped structure. The diamond - shaped pin handle 54 can be directly rotated by hand without tools, which is very convenient.

[0041] The hook groove 55 is a semi - arc - shaped groove and is opened at the lower end of the sampling plate 5. The inner groove wall of the hook groove 55 is provided with an anti - slip layer 56. The anti - slip layer 56 is a damping silicone material coating. When the finger hooks into the hook groove 5​​Operating mode: During sampling, the vacuum pump 3 can be started for a period of time and then turned off. A negative pressure will be formed in the inner cavity of the sampler 4 through the air extraction pipe 33. A certain amount of external air can be drawn into the sampler 4 through the sampling pipe 6 to achieve the sampling effect. At this time, when the certain amount of air hits the sampling medium 51 on the sampling plate 5, the microbial particles in the air will be sampled and captured on the sampling plate 5 with the sampling medium 51 for later sampling and detection (this is the existing technology).

[0043] After sampling, cylinder 7 is activated, which drives the cover 8 to move downwards stably via the top frame 71. The sealing ring 81 then effectively and completely seals the opening at the top of the sampling tube 6. Cylinder 7 is then closed to prevent external dust particles from naturally entering the sampler 4 through the sampling tube 6, thereby effectively preventing contamination of the microbial particle samples collected on the sampling plate 5 and ensuring the results of subsequent environmental air microbial sampling.

[0044] Moreover, once the sampling platform 1 is moved to the laboratory and positioned, the pin handle 54 can be rotated counterclockwise to rotate the screw pin 53 counterclockwise and remove it. Then, by inserting a finger into the hook groove 55 and pulling, the sampling plate 5 can be quickly and easily pulled out along the sealing groove 41, which improves the convenience of removing the sampling plate 5 from the sampler 4.

[0045] In addition, by releasing the brakes on the casters 13, one can then grasp the handles 11. Since there are handles 11 in all four directions, the sampling platform 1 can be easily pushed in all four directions, improving the mobility of the environmental microbial sampler for outdoor sampling.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
