Description

Technical Field

[0001] This utility model relates to the field of microbial aerosol detection technology, and in particular to a microbial aerosol early warning sampling device and a drone equipment, which is used on a drone. Background Technology

[0002] Microorganisms from humans, animals, plants, and soil can be distributed into the air through droplets or dust, resulting in a certain variety and quantity of microorganisms in the air. Theoretically, pathogenic microorganisms are generally not present in the air, but aerosols of pathogenic microorganisms are often suspended in the air near hospitals, veterinary clinics, and livestock sheds, and healthy people or animals can often become infected by inhaling them. Air contaminated with pathogenic microorganisms can often become a source or medium of pollution, causing epidemics of infectious diseases. Therefore, airborne microbial testing is of great significance for the prevention and control of infectious diseases, as well as for the hygienic monitoring and protection of the environment.

[0003] Currently, sampling of airborne microbial aerosols mainly involves fixed-point sampling or manual mobile sampling. These traditional sampling methods have drawbacks such as low sampling efficiency, uncertain sampling time, human interference, and the risk of human infection.

[0004] To address the aforementioned problems and shortcomings, the microbial aerosol sampler is combined with drone technology, which greatly expands the usable space of the microbial aerosol sampler. It is upgraded from traditional point sampling and planar sampling to three-dimensional sampling, making the sampling results more representative and more practically significant for the prevention and control of pathogenic microbial aerosol infections.

[0005] Traditional microbial aerosol samplers are used for air sampling. However, traditional air sampling is indiscriminate and lacks specificity. It cannot achieve the function of sampling only when an alarm is triggered and not sampling when no alarm is triggered. Utility Model Content

[0006] This invention addresses the problems and shortcomings of existing technologies by providing a novel microbial aerosol early warning sampling device and unmanned aerial vehicle (UAV) equipment.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] This utility model provides a microbial aerosol early warning sampling device, characterized in that it includes a housing, on which an alarm module, a sampling module, and a main controller for controlling the alarm module to alarm and the sampling module to sample are fixed, and the alarm module and the sampling module are electrically connected to the main controller.

[0009] The alarm module includes an alarm-end air sampling head, an air pump, an alarm sampling optical module, an air filter, and an alarm. The alarm-end air sampling head is embedded in the top of the housing. The air pump and the alarm sampling optical module are fixed inside the housing. The air filter and the alarm are embedded in the housing. The alarm-end air sampling head is connected to the air inlet of the alarm sampling optical module through the air pump. The air filter is connected to the air outlet of the alarm sampling optical module. The air pump, the alarm sampling optical module, and the alarm are all electrically connected to the main controller.

[0010] The sampling module includes a sampling end air sampling head and a sampling component. The sampling end air sampling head is embedded in the top of the housing, and the sampling component is fixed inside the housing. The sampling end air sampling head is connected to the air inlet of the sampling component, and the sampling component is electrically connected to the main controller.

[0011] The positive and progressive effects of this utility model are as follows:

[0012] This invention applies microbial aerosol alarm technology to airborne microbial sampling, enabling effective collection of airborne microbial aerosols. Compared to the blind and non-targeted nature of traditional air sampling, this invention incorporates microbial aerosol alarm technology and designs a microbial aerosol early warning sampling device for use with drones. This device enables sampling only when an alarm is triggered, achieving integrated reconnaissance and sampling, making microbial aerosol sampling more targeted.

[0013] This utility model of microbial aerosol early warning sampling device can sample locations in the environment that are easily accessible to people, as well as locations in the environment that are inaccessible to people, such as building rooftops, conference center rooftops, and stadium rooftops.

[0018] like Figure 1-8 As shown, this embodiment provides a microbial aerosol early warning sampling device, which can be used in conjunction with a drone to sample locations in the environment that are easily accessible to people, as well as locations in the environment that are inaccessible to people, such as building rooftops, conference center rooftops, and stadium rooftops.

[0019] The microbial aerosol early warning sampling device includes a housing 1. An alarm module, a sampling module, and a main controller controlling the alarm module and sampling module are fixed on the housing 1. Both the alarm module and the sampling module are electrically connected to the main controller. A control board 2 is fixed on the inner wall of the rear shell of the housing 1. The main controller is mounted on the control board 2, which can employ a high-performance 32-bit ARM microprocessor. The control board 2 may also include a GPS positioning module for locating the current flight position of the microbial aerosol early warning sampling device.

[0020] Specifically, the alarm module includes an alarm-end air sampling head 3, an air pump 4, an alarm sampling optical module 5, an air filter 6, an alarm indicator light 7, and an alarm buzzer 8. The alarm-end air sampling head 3 is embedded in the top of the housing 1. The air pump 4, the alarm sampling optical module 5, and the alarm buzzer 8 are fixed inside the housing 1. The air filter 6 and the alarm indicator light 7 are embedded in the housing 1. The alarm-end air sampling head 3 is connected to the air inlet of the alarm sampling optical module 5 through the air pump 4, and the air filter 6 is connected to the air outlet of the alarm sampling optical module 5. The air pump 4, the alarm sampling optical module 5, the alarm indicator light 7, and the alarm buzzer 8 are all electrically connected to the main controller. The alarm sampling optical module 5 uses fluorescence technology to sample microbial particles in the air to form a fluorescence signal, and adopts an existing optical module design. The air pump 4, the air filter 6, the alarm indicator light 7, and the alarm buzzer 8 are all existing products. A bracket 9 is fixed inside the housing 1, and the alarm sampling optical module 5 is installed on the bracket 9. The air pump 4 is fixed at the bottom inside the housing 1.

[0021] The alarm-end air sampling head 3 includes an alarm-end air sampling port 301 and an alarm-end rainproof cap 302. The alarm-end air sampling port 301 is embedded in the top of the housing 1, and the alarm-end rainproof cap 302 is supported directly above the alarm-end air sampling port 301. A gap is left between the alarm-end air sampling port 301 and the alarm-end rainproof cap 302 so that the alarm-end rainproof cap 302 does not block the alarm-end air sampling port 301. The bottom end of the alarm-end air sampling port 301 is connected to the air pump 4.

[0022] An alarm clearing button 10 is embedded in the housing 1, and the alarm clearing button 10 is electrically connected to the main controller. When an alarm occurs, pressing the alarm clearing button 10 will clear the alarm.

[0023] The working principle of the alarm module and the main controller that controls the alarm module is as follows: The main controller controls the air pump 4 and the alarm sampling optical module 5 to start working. The air pump 4 pumps the air entering the alarm end air sampling head 3 into the alarm sampling optical module 5. The alarm sampling optical module 5 uses fluorescence technology to sample the current microbial particles in the air and transmits the data to the main controller. If the main controller analyzes and finds that the number of microbial particles has increased (such as the concentration of microbial aerosols in the current microbial particles being greater than the set threshold), it controls the alarm indicator 7 to light up and the alarm buzzer 8 to sound to provide an early warning. At the same time, it controls the sampling module to start working during the early warning. The air discharged from the outlet of the alarm sampling optical module 5 enters the air filter 6, and the air filter 6 filters out the bioaerosols in the air before discharging them.

[0024] The sampling module includes an air sampling head 11, a motor driver 12, a fan 13, a wet-wall cyclone sampler 14, a sampling liquid bottle 15, a sample bottle 16, a replenishment peristaltic pump 17, and a sampling peristaltic pump 18. The air sampling head 11 is embedded in the top of the housing 1. The motor driver 12, fan 13, wet-wall cyclone sampler 14, sampling liquid bottle 15, sample bottle 16, replenishment peristaltic pump 17, and sampling peristaltic pump 18 are fixed inside the housing 1. The sampling liquid bottle 15 and sample bottle 16 are detachably fixed inside the housing 1. The motor driver 12, fan 13, wet-wall cyclone sampler 14, replenishment peristaltic pump 17, and sampling peristaltic pump 18 are all existing products.

[0025] Specifically, the wet-wall cyclone sampler 14 has an independent, non-connected air inlet 141 and exhaust outlet 142 at its top and a three-way pipe 143 connected to its bottom. A mounting plate 19, consisting of an upper vertical plate, a left-extending middle horizontal plate, and a downward-extending lower vertical plate, is fixed inside the housing 1. A fan mounting plate 20 is fixed to the top of the middle horizontal plate of the mounting plate 19 via a support column 38. The fan mounting plate 20 is located directly above the middle horizontal plate of the mounting plate 19. The wet-wall cyclone sampler 14 is embedded in the middle horizontal plate of the mounting plate 19. The air inlet 141 of the wet-wall cyclone sampler 14 is connected to the air sampling head 11 at the sampling end via a sampler connecting pipe 21. A fan 13 is embedded in the fan mounting plate 20. The exhaust port 142 of the wall-mounted cyclone sampler 14 is connected to the air inlet of the fan 13. The first port of the three-way pipe 143 serves as a liquid replenishment port, connected to the sampling liquid bottle 15 via a liquid replenishment peristaltic pump 17; the second port serves as a sampling port, connected to the sample bottle 16 via a sampling peristaltic pump 18; and the third port is connected to the bottom of the wet-walled cyclone sampler 14. The air outlet of the fan 13 is connected to a fan outlet pipe 22, which extends out of the housing 1. A flow sensor 23 is connected to the fan outlet pipe 22. The fan 13 is electrically connected to the main controller via a motor driver 12. The wet-walled cyclone sampler 14, the liquid replenishment peristaltic pump 17, the sampling peristaltic pump 18, and the flow sensor 23 are all electrically connected to the main controller. The flow sensor 23 installed at the air outlet of the fan 13 facilitates real-time detection of the fan flow rate, thereby enabling the main controller to control the fan speed in real time and achieve precise control of the sampling flow rate.

[0026] Furthermore, a waterproof cover 24 for the air outlet pipe 22 is fixed on the housing 1 and directly above the air outlet pipe 22 of the fan. The waterproof cover 24 is used to waterproof the air outlet pipe 22 of the fan that is exposed on the housing 1.

[0027] Furthermore, the sampling end air sampling head 11 includes a sampling end air sampling port 111 and a sampling end rainproof cap 112. The sampling end air sampling port 111 is embedded in the top of the housing 1. A waterproof cap support 113 is fixed to the top of the sampling end air sampling port 111 along the circumferential direction. The sampling end rainproof cap 112 is supported on the waterproof cap support 113. A gap is left between the sampling end air sampling port 111 and the sampling end rainproof cap 112 so that the sampling end rainproof cap 112 does not block the sampling end air sampling port 111. The bottom end of the sampling end air sampling port 111 is connected to the air inlet 141 of the wet wall cyclone sampler 14 through the sampler connecting pipe 21.

[0028] In this embodiment, a temperature and humidity sensor 25 is embedded in the housing 1, and the temperature and humidity sensor 25 is electrically connected to the main controller. The temperature and humidity sensor 25 is used to detect the temperature and humidity of the current flight position.

[0029] In this embodiment, the air sampling head 3 at the alarm end is a low-flow sampling head, and the air sampling head 11 at the sampling end is a high-flow sampling head, that is, the diameter of the air sampling head 3 at the sampling end is larger than the diameter of the air sampling head 11 at the alarm end.

[0030] In this embodiment, a battery box 26 with an opening is fixed inside the housing 1 near the rear surface. The battery box 26 contains a battery 37. A battery door 27 covering the opening of the battery box 26 is embedded in the rear surface of the housing 1, and a battery door handle 28 is fixed on the battery door 27. Moreover, the battery 37 is a rechargeable battery. A power board 29 is fixed on the inner wall of the rear surface of the housing 1, and a charging interface 30 is embedded in the rear surface of the housing 1. A power management module (existing module) is arranged on the power board 29. The rechargeable battery 37 can be charged through the charging interface 30, and the power management module manages the charging and discharging of the battery 37.

[0031] In this embodiment, in order to adapt to the needs of drones and reduce drag during flight, an elliptical head 31 is fixed on the front shell surface of the shell 1; in order to facilitate the removal of the sample bottle 16 and the sampling liquid bottle 15 inside the shell 1, the front shell surface of the shell 1 is detachably connected to the shell 1, such as by bolts.

[0032] In this embodiment, in order to facilitate the handling of this microbial aerosol early warning sampling device, a gripping groove 32 is provided on the opposite side of the housing 1.

[0033] In this embodiment, a communication interface 33 and a USB interface 34 are also embedded on the rear shell surface of the housing 1. The communication interface 33 and the USB interface 34 can be used to transmit data from the main controller to the host computer.

[0034] In this embodiment, a toggle switch 35 is also embedded on the rear shell surface of the housing 1, and the toggle switch 35 is used to control the on / off of this microbial aerosol early warning sampling device.

[0035] In this embodiment, mounting holes 36 are fixed at the four corners of the bottom of the housing 1. These four mounting holes 36 can be used to mount the microbial aerosol early warning sampling device on a drone.

[0036] This embodiment also provides a drone device, which includes a drone and the aforementioned microbial aerosol early warning sampling device. The microbial aerosol early warning sampling device is mounted on the drone through four mounting holes 36. If the drone has mounting holes that match the four mounting holes 36 one by one, four bolts are used to connect the corresponding mounting holes, thereby enabling the microbial aerosol early warning sampling device to be mounted on the drone.

[0037] During operation, the drone flies to the area to be detected. The GPS positioning module can locate the drone's position within the area. Once in the area, the drone flies within it. The main controller activates the air pump 4 and the alarm sampling optical module 5. The air pump 4 pumps the air entering the alarm sampling head 3 into the alarm sampling optical module 5. The alarm sampling optical module 5 uses fluorescence technology to sample the current microbial particles in the air and transmits the data to the main controller. If the main controller detects an increase in microbial particles, it activates the alarm indicator 7 and sounds the alarm buzzer 8 to provide an early warning. Simultaneously, the sampling module is activated during the warning. The air discharged from the outlet of the alarm sampling optical module 5 enters the air filter 6, which filters out the bioaerosols in the air before discharging them.

[0038] When the sampling module is working, it first controls the start of the replenishment peristaltic pump 17 to pump the sampling liquid in the sampling liquid bottle 15 into the wet wall cyclone sampler 14 through the first port of the three-way pipe 143. Then, the main controller controls the motor driver 12 to drive the fan 13 to start. The air containing microbial particles enters the wet wall cyclone sampler 14 for sampling through the sampling end air sampling head 11, the sampler connecting pipe 21 and the air inlet 141 in sequence.

[0039] After sampling is completed according to the preset time, only the sampling peristaltic pump 18 is started (the replenishment peristaltic pump 17 and the blower 13 are suspended). The sample liquid containing bioaerosol particles collected in the wet-wall cyclone sampler 14 is transported to the sample bottle 16 through the second port of the three-way tube 143, completing the bioaerosol particle collection. After the sampling is completed, the drone returns to the base, and the sample bottle 16 and the sampling liquid bottle 15 are manually removed.

[0040] It should be noted that, based on the functions of the various port pins of the high-performance 32-bit ARM microprocessor used by the main controller, the electrical connection between the various electronic components (air pump 4, alarm sampling optical module 5, alarm indicator light 7, alarm buzzer 8, motor driver 12, wet wall cyclone sampler 14, replenishing peristaltic pump 17, sampling peristaltic pump 18, and flow sensor 23, etc.) and the specific port pin of the high-performance 32-bit ARM microprocessor is a conventional setting for those skilled in the art and is existing technology.

[0041] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
