Description

Technical Field

[0001] The invention relates to an aerosol detector, in particular to an environmentally adaptable bioaerosol detector used in the field of aerosol collection. Background Art

[0002] Bioaerosols refer to tiny particles such as microorganisms, pollen, fungal spores, etc. suspended in the air, which may have negative effects on human health. Therefore, bioaerosol detectors have wide application value in environmental monitoring, public health and other fields. Bioaerosol detectors usually use optical, electrochemical or biosensor technologies to detect bioaerosols in the air. By capturing and analyzing particulate matter in the air, the detector can monitor and report changes in bioaerosol concentration in real time.

[0003] The specification of invention patent 202310467975.4 discloses an intelligent mobile aerosol collection robot. The application realizes intelligent sampling of aerosols in large spaces, reduces the workload of manual aerosol sampling, expands the application scenarios of robot aerosol sampling, realizes remote control of the robot's moving route, and improves the efficiency of the robot's automatic movement and real-time collection of aerosols. The avoidance device improves the intelligence level of the robot and extends the service life of the robot.

[0004] However, the mobile aerosol collection machine in the above application can only be used for detection in a fixed environment. When the mobile aerosol collection device is moved to a new detection environment, the staff needs to set new parameters for the aerosol collection device according to the detection object to meet the usage requirements. The aerosol collection device cannot adjust the settings by itself, and the staff needs to have corresponding knowledge reserves. The threshold for use is high, and it is difficult to adapt to multiple common usage environments at the same time. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing aerosol collection instruments cannot adjust the settings by themselves, and the staff are required to have corresponding knowledge reserves. The threshold for use is high and it is difficult to adapt to multiple common usage environments at the same time.

[0006] In order to solve the above problems, the present invention provides an environmentally adaptable bioaerosol detector, comprising a moving part, the moving part comprising a counterweight part and a mounting part matching each other, a connecting part fixedly connected between the counterweight part and the mounting part, an anti-overturning unit sleeved on the outer side of the connecting part, the anti-overturning unit comprising an elastic shell, the lower end of the elastic shell wraps the counterweight part, a reinforcing net is buried at one end of the elastic shell away from the connecting part, the reinforcing net is woven from a plurality of elastic ropes, a high-density solution is filled in the elastic shell, the high-density solution is made of non-toxic inorganic salt dissolved in liquid water, the upper end of the moving part is fixedly connected to a superstructure, and the upper end of the superstructure is fixedly connected to an interactive part;

[0007] The bioaerosol detector also includes a central control module, which is signal-connected to the functional module. The central control module is signal-connected to the acquisition module, sampling module, detection module, interaction module, mobile module and balance module, and the functional module is electrically connected to the central control module, acquisition module, sampling module, detection module, interaction module, mobile module and balance module, respectively. The functional module and the central control module are arranged in the mobile part, the mobile module is arranged in the mobile part, the main body of the balance module is the anti-overturning unit, the main body of the interaction module is the interaction part, the light-weight structures of the acquisition module, sampling module and detection module are located in the superstructure, and the heavy-weight structure thereof is located in the mobile part, so that the center of gravity of the mobile part as a whole is lowered and not easy to overturn. At the same time, the central control module, energy supply module, acquisition module, sampling module, detection module, interaction module, mobile module and balance module are all lightweighted, and the overall mass of the anti-overturning unit is greater than half of the other structures of the aerosol detector;

[0008] The method of using the bioaerosol detector includes: the collection module will collect aerosol samples in the environment under the control of the central control module, and transport them to the sampling module for sampling to meet the detection requirements, and finally transport them to the detection module for detection. The bioaerosol detector completes the preset work under the control of the central control module, and when the bioaerosol detector is moved to other environments, the central control module will change the working state of the bioaerosol detector according to the detection results of the detection module: when the detection module detects a target object, including but not limited to high concentrations of particulate matter, harmful gases and specific viruses, the central control module switches its own detection mode according to the detected target object, and changes the detection object from a broad-spectrum detection object to a detected target object, so that the bioaerosol detector is more in line with the current environment.

[0009] In the above-mentioned environmentally adaptable bioaerosol detector, the bioaerosol detector can adjust settings automatically without requiring the staff to have corresponding knowledge reserves. The threshold for use is low and it is easy to adapt to a variety of common use environments.

[0010] As a further improvement of the present application, the interaction modes of the interaction module include voice control interaction and touch screen interaction, and the types of interaction are increased to meet the needs of different users.

[0011] As a further improvement of the present application, the mobile module includes a moving part, a power unit and a ranging unit to meet the requirements of normal movement of the bioaerosol detector.

[0012] As a further improvement of the present application, the working modes of the bioaerosol detector include standby mode, low power mode and high power mode. When the bioaerosol detector is stationary, it is in standby mode and periodically starts to low power mode for regular detection. When the bioaerosol detector is moving, it is in high power mode. The working state of the bioaerosol detector is reasonably designed to reduce power consumption and extend the usage time without affecting the accuracy of its detection results.

[0013] As another improvement of the present application, the movement modes of the bioaerosol detector include low-speed cruising, temporary pause and stillness. When the bioaerosol detector detects a moving target nearby during low-speed cruising, it temporarily pauses and does not take evasive action. The moving target evades the target on its own to avoid a collision accident caused by both parties avoiding the target at the same time, thereby increasing the safety of the movement of the bioaerosol detector.

[0014] As another improvement supplement of the present application, a plurality of filling balls are doped in the high-density solution, and the plurality of filling balls are suspended in the high-density solution. The filling balls include an elastic spherical shell, which is a hollow structure with a plurality of through holes drilled on the elastic spherical shell. The arrangement of the filling balls can increase the overall impact resistance of the anti-overturning unit. When the anti-overturning unit is impacted by external force, the impact of the external force on the moving part and the superstructure can be reduced through mutual collision between the plurality of filling balls.

[0015] As another improvement supplement of the present application, the outer wall of the elastic spherical shell is coated with a homopolar magnetic coating, and the multiple elastic spherical shells move away from each other under the action of the homopolar magnetic coating, so that the multiple filling balls move away from each other, increasing the cushioning effect of the multiple filling balls. At the same time, in the process of the anti-rollover unit recovering its deformation, the filling balls can drive the high-density solution to move, slowing down the recovery speed of the anti-rollover unit, and giving the moving part and the superstructure more time to adjust their posture.

[0016] As another improved supplement of the present application, a plurality of support columns are fixedly connected to the inner wall of the elastic spherical shell, and the plurality of support columns intersect at the center of the elastic spherical shell, thereby reducing the probability of deformation of the filling ball and increasing the effective utilization rate of the filling ball.

[0017] In summary, in the present application, when the bioaerosol detector is moved to other environments, the central control module will change the working state of the bioaerosol detector according to the detection results of the detection module: when the detection module detects a target object, the central control module switches its own detection mode according to the detected target object, so that the bioaerosol detector is more in line with the current environment, and the bioaerosol detector can adjust its settings by itself. There is no need for staff to have corresponding knowledge reserves, the usage threshold is low, and it is easy to adapt to a variety of common usage environments.

[0018] Once the bioaerosol detector tips over during movement, it will partially squeeze the anti-tipping unit, causing the high-density salt solution filled in the elastic shell to flow in the opposite direction of the tipping, that is, the counterweight center of the moving part and the anti-tipping unit moves in the opposite direction of the tipping of the superstructure and the interaction part, so that the bioaerosol detector can return to normal under the action of the movement of the center of gravity of the moving part and the anti-tipping unit, so that the bioaerosol detector has a certain self-regulation ability and is not prone to complete tipping.

[0019] Finally, by adding filling balls to the high-density solution, the overall impact resistance of the anti-rollover unit was increased. When the anti-rollover unit is impacted by external force, the impact of the external force on the moving part and the superstructure can be reduced through the mutual collision between multiple filling balls. At the same time, the same-polar magnetic coating makes the multiple filling balls move away from each other, increasing the buffering effect of the multiple filling balls. In the process of the anti-rollover unit recovering its deformation, the filling balls can drive the high-density solution to move, slowing down the recovery speed of the anti-rollover unit and giving the moving part and the superstructure more time to adjust their posture.

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-2 An environmentally adaptable bioaerosol detector is shown, comprising a moving part 1, the moving part 1 comprising a counterweight part 101 and a mounting part 103 that match each other, a connecting part 102 fixedly connected between the counterweight part 101 and the mounting part 103, an anti-overturning unit 2 is sleeved on the outer side of the connecting part 102, the anti-overturning unit 2 comprises an elastic shell 201, the lower end of the elastic shell 201 covers the counterweight part 101, a reinforcing net 202 is buried at one end of the elastic shell 201 away from the connecting part 102, the reinforcing net 202 is woven from a plurality of elastic ropes, a high-density solution is filled in the elastic shell 201, and the high-density solution is made of non-toxic inorganic salt dissolved in liquid water, a superstructure 3 is fixedly connected to the upper end of the moving part 1, and an interactive part 4 is fixedly connected to the upper end of the superstructure 3;

[0035] See also Figure 5-6 The environmentally adaptable bioaerosol detector also includes a central control module, which is signal-connected to the functional module. The central control module is signal-connected to the acquisition module, the sampling module, the detection module, the interaction module, the mobile module and the balance module, and the functional module is electrically connected to the central control module, the acquisition module, the sampling module, the detection module, the interaction module, the mobile module and the balance module, respectively. The functional module and the central control module are arranged in the mobile part 1, the mobile module is arranged in the mobile part 1, the main body of the balance module is the anti-overturning unit 2, the main body of the interaction module is the interaction part 4, the light-weight structures of the acquisition module, the sampling module and the detection module are located in the superstructure 3, and the heavy-weight structure thereof is located in the mobile part 1, so that the center of gravity of the mobile part 1 as a whole is lowered and not easy to overturn. At the same time, the central control module, the energy supply module, the acquisition module, the sampling module, the detection module, the interaction module, the mobile module and the balance module are all light-weighted, and the overall mass of the anti-overturning unit 2 is greater than half of the other structures of the aerosol detector;

[0036] The energy supply module provides power to other modules to facilitate normal operation, and the central control module regulates the normal operation of each working module. The collection module, sampling module and detection module complete the collection, sampling and detection of aerosol samples under the control of the central control module, and transmit the detection results back to the central control module. The interactive module allows users to adjust the working procedures in the central control module and also to review the detection results in real time. The mobile module and the balance module are convenient for mobile collection of bioaerosol detectors and their mobile safety.

[0037] The method of using the bioaerosol detector includes: the collection module will collect aerosol samples in the environment under the control of the central control module, and transport them to the sampling module for sampling to meet the detection requirements, and finally transport them to the detection module for detection. The bioaerosol detector completes the preset work under the control of the central control module, and when the bioaerosol detector is moved to other environments, the central control module will change the working state of the bioaerosol detector according to the detection results of the detection module: when the detection module detects a target object, including but not limited to high concentrations of particulate matter, harmful gases and specific viruses, the central control module switches its own detection mode according to the detected target object, and changes the detection object from a broad-spectrum detection object to a detected target object, so that the bioaerosol detector is more in line with the current environment.

[0038] The detection mode of the bioaerosol detector is preset in the central control module by technical personnel in this field. At the same time, the detection mode that best suits the current environment can be determined based on the manual control data and detection results existing in the Internet of Things, so that the bioaerosol detector can adjust itself. There is no need for staff to have corresponding knowledge reserves, the threshold for use is low, and it is easy to adapt to a variety of common usage environments.

[0039] See also Figure 3-4 In the present application, once the bioaerosol detector falls over during movement, the anti-overturning unit 2 will be partially squeezed, so that the high-density salt solution filled in the elastic shell 201 flows in the opposite direction of the overturning, that is, the counterweight center of the moving part 1 and the anti-overturning unit 2 moves in the opposite direction of the overturning of the superstructure 3 and the interactive part 4, so that the bioaerosol detector can return to normal under the action of the movement of the center of gravity of the moving part 1 and the anti-overturning unit 2, so that the bioaerosol detector has a certain self-regulation ability and is not prone to complete overturning.

[0040] In particular, the dimensions of each structure in the present application are not drawn strictly in proportion, and those skilled in the art can reasonably design the dimensions of each structure according to actual conditions. For example, in order to adapt to rugged roads, the height of the counterweight part 101 can be appropriately raised to increase the overall stability of the bioaerosol detector.

[0041] The interaction modes of the interactive module include voice control interaction and touch screen interaction, and the types of interaction are increased to meet the needs of different users.

[0042] The mobile module includes a mobile part 1, a power unit and a distance measuring unit to meet the requirements of normal movement of the bioaerosol detector.

[0043] See also Figure 6 The working modes of the bioaerosol detector include standby mode, low power mode and high power mode. When the bioaerosol detector is stationary, it is in standby mode and periodically starts to low power mode for regular detection. When the bioaerosol detector is moving, it is in high power mode. The working state of the bioaerosol detector is reasonably designed to reduce power consumption and extend the use time without affecting the accuracy of its detection results.

[0044] See also Figure 7 The movement modes of the bioaerosol detector include low-speed cruising, temporary pause and stationary. When the bioaerosol detector detects a moving target nearby during low-speed cruising, it will temporarily pause and not take evasive action. The moving target will evade on its own to avoid collision accidents caused by both parties evading at the same time, thereby increasing the safety of the movement of the bioaerosol detector.

[0045] The second implementation method:

[0046] Figure 8-10 An environmentally adaptable bioaerosol detector is shown, in which a plurality of filling balls 5 are doped in a high-density solution, and the plurality of filling balls 5 are all suspended in the high-density solution. The filling balls 5 include an elastic spherical shell 501, and the elastic spherical shell 501 is a hollow structure. A plurality of through holes 502 are drilled on the elastic spherical shell 501. The arrangement of the filling balls 5 can increase the overall impact resistance of the anti-overturning unit 2. When the anti-overturning unit 2 is impacted by an external force, the impact of the external force on the moving part 1 and the superstructure 3 can be reduced by mutual collision between the plurality of filling balls 5.

[0047] The outer wall of the elastic spherical shell 501 is coated with a homopolar magnetic coating. Under the action of the homopolar magnetic coating, the multiple elastic spherical shells 501 move away from each other, so that the multiple filling balls 5 move away from each other, increasing the cushioning effect of the multiple filling balls 5. At the same time, in the process of the anti-overturning unit 2 recovering its deformation, the filling balls 5 can drive the high-density solution to move, slowing down the recovery speed of the anti-overturning unit 2, and giving the moving part 1 and the superstructure 3 more time to adjust their posture.

[0048] The inner wall of the elastic spherical shell 501 is fixedly connected with a plurality of support columns 503 , and the plurality of support columns 503 intersect at the center of the elastic spherical shell 501 , thereby reducing the probability of deformation of the filling ball 5 and increasing the effective utilization rate of the filling ball 5 .

[0049] Similar to the first embodiment, in the present application, the overall impact resistance of the anti-overturning unit 2 is increased by adding filling balls 5 to the high-density solution. When the anti-overturning unit 2 is impacted by external force, the impact of the external force on the moving part 1 and the superstructure 3 can be reduced by the mutual collision between the multiple filling balls 5. At the same time, the same-polarity magnetic coating makes the multiple filling balls 5 move away from each other, increasing the buffering effect of the multiple filling balls 5. In the process of the anti-overturning unit 2 recovering its deformation, the filling balls 5 can drive the high-density solution to move, slowing down the recovery speed of the anti-overturning unit 2, and giving the moving part 1 and the superstructure 3 more time to adjust their posture.

[0050] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
