Description

Technical Field

[0001] This utility model belongs to the field of gas transfer technology, and more specifically, it relates to a sample retention container for monitoring pollution sources using unmanned aerial vehicles (UAVs). Background Technology

[0002] In the field of UAV pollution source monitoring, gas sampling containers are the core components for collecting and transporting polluted gases, but their existing structural design is difficult to meet the requirements of efficient and stable operation. Currently, traditional sampling containers have complex structures, and gas collection and transportation are mostly carried out outdoors at high altitudes. Ultimately, the sampling container must be placed on a sampling container base to complete the transportation work.

[0003] While existing sample collection containers can collect gas, they rely solely on gravity to maintain the connection between the container and its base. Although this method is simple, increased external wind speeds can cause the gas passage between the container and base to become unsealed or even separate, leading to gas leakage, rework, and unnecessary trouble. Furthermore, most sample collection containers on the market employ complex locking mechanisms. While these can initially achieve proper positioning, their complexity and tendency to deviate after repeated use result in incomplete positioning. Utility Model Content

[0004] The purpose of this invention is to provide a sample retention container for monitoring pollution sources using unmanned aerial vehicles (UAVs), aiming to solve the problem that the sample retention container cannot be effectively and quickly positioned on the base.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: providing a sample retention container for monitoring pollution sources using unmanned aerial vehicles (UAVs), comprising: The barrel body has a lifting device on its top for gripping with a robotic arm; A sampling bag, placed inside the barrel, is used to collect gas; An air outlet is connected to the bottom of the sampling bag, and the air outlet is used to dock with the base of the sample container; A solenoid valve is installed between the air outlet and the sampling bag. The solenoid valve is used to control the opening and closing of the air passage between the sampling bag and the air outlet. An adsorption ring is installed at the bottom of the barrel body. The adsorption ring is used to adsorb and position the sample barrel base.

[0006] In one possible implementation, a pneumatic head is provided between the solenoid valve and the sampling bag, and the number of sampling bags is multiple. The pneumatic head is used to guide the gas from the multiple sampling bags to the solenoid valve.

[0007] In one possible implementation, the adsorption ring is an iron ring, and the adsorption ring is disposed on the bottom surface of the barrel.

[0008] In one possible implementation, the air outlet is a downward-facing flared opening, and the air outlet extends to the outside of the barrel body.

[0009] In one possible implementation, the lifting component is a lifting head, and an annular groove for cooperating with lifting is provided along the circumference of the lifting head.

[0010] In one possible implementation, the barrel includes an upper shell, a barrel body, and a lower shell; the lifting head is fixed to the upper shell; the adsorption ring is fixed to the bottom surface of the lower shell; and the sampling bag is disposed inside the barrel body.

[0011] In one possible implementation, a plurality of connecting rods connect the upper shell and the lower shell.

[0012] In one possible implementation, both the upper shell and the lower shell are detachably connected to the barrel body.

[0013] In one possible implementation, the bottom of the lower shell is provided with a power supply receiver, which is electrically connected to the solenoid valve. The power supply receiver is used to receive the electrical energy transmitted by the sample container base and to supply power to the solenoid valve.

[0014] In one possible implementation, the power receiving end is a wireless coil, and the projection of the power receiving end on the lower shell is located outside the adsorption ring.

[0015] The beneficial effects of the sample retention container for monitoring pollution sources from unmanned aerial vehicles (UAVs) provided by this utility model are as follows: Compared with the prior art, the sample retention container for monitoring pollution sources from UAVs of this utility model has a lifting device at the top of the container body, and the sampling bag is placed inside the container body. An air outlet is provided below the sampling bag, and a solenoid valve is installed between the air outlet and the sampling bag. An adsorption ring is installed at the bottom of the container body.

[0016] In practical applications, the adsorption ring adheres to the base of the sample container. At this point, the gas passage between the sampling bag and the outlet is opened via a solenoid valve, allowing the gas inside the sampling bag to be discharged into the sample container base through the solenoid valve and outlet. The entire sample container can be transferred using a lifting device after both the bag and outlet are complete. This application enables long-distance gas sampling and transport, allowing the sample container to be quickly and easily positioned on the base, ensuring stable gas transfer.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to the following: Figures 1 to 3 The present invention provides a sample retention container for monitoring pollution sources from unmanned aerial vehicles (UAVs). The sample retention container includes: a container body, a sampling bag, an outlet nozzle 7, a solenoid valve 8, and an adsorption ring 11. A lifting device 2 for gripping with a robotic arm is provided at the top of the container body. The sampling bag is located inside the container body and is used to collect gas. The outlet nozzle 7 is connected to the bottom of the sampling bag and is used to dock with the sample retention container base 5. The solenoid valve 8 is installed between the outlet nozzle 7 and the sampling bag, and is used to control the opening and closing of the gas passage between the sampling bag and the outlet nozzle 7. The adsorption ring 11 is installed at the bottom of the container body and is used to adsorb and position itself within the sample retention container base 5.

[0022] The beneficial effects of the sample retention container for monitoring pollution sources from unmanned aerial vehicles (UAVs) provided by this utility model are as follows: Compared with the prior art, the sample retention container for monitoring pollution sources from UAVs of this utility model has a lifting device 2 at the top of the container body, and a sampling bag is placed inside the container body. An air outlet 7 is provided below the sampling bag, and a solenoid valve 8 is installed between the air outlet 7 and the sampling bag. An adsorption ring 11 is installed at the bottom of the container body.

[0023] In practical applications, the adsorption ring 11 can be adsorbed inside the sample container base 5. At this time, the gas passage between the sampling bag and the gas outlet 7 is opened by the solenoid valve 8, and the gas in the sampling bag can be discharged into the sample container base 5 through the solenoid valve 8 and the gas outlet 7. The entire sample container can be transferred by the lifting component 2 after the gas is filled and discharged. This application enables long-distance gas sampling and transportation, and allows the sample container to be quickly and conveniently positioned on the base 5, ensuring stable gas transfer.

[0024] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 and Figure 2 A pneumatic head 9 is provided between the solenoid valve 8 and the sampling bag. There are multiple sampling bags. The pneumatic head 9 is used to guide the gas from multiple sampling bags to the solenoid valve 8.

[0025] By installing the pneumatic head 9, air can be injected into the corresponding sampling bag. In one embodiment, by remotely controlling the pneumatic head 9, a designated pneumatic head 9 passage can be opened, allowing gas to enter the designated sampling bag. This enables the collection of gases from different sources within a single container. During degassing, by controlling the pneumatic head 9, gases from different sources can be discharged through the outlet 7 in sequence.

[0026] Furthermore, the pneumatic head 9 includes multiple gas channels, each corresponding to a sampling bag. This design allows for more precise gas flow, accurately directing gases from different sources to their respective sampling bags. In actual operation, when collecting gas samples from multiple pollution sources, the correspondence between each gas channel and sampling bag is pre-set based on the location and characteristics of the different pollution sources. Then, by remotely controlling the pneumatic head 9, the corresponding gas channel is opened, and the gas enters the designated sampling bag along the predetermined path.

[0027] After data collection, during the venting operation, the pneumatic head 9 is used to control the sequential opening of each gas passage according to a pre-set order. This allows gases from different sources to be discharged through the outlet 7, facilitating subsequent analysis and detection of different gas samples. In practical applications, the design of the sample container and its pneumatic head 9 for UAV pollution source monitoring plays a crucial role. For example, when monitoring pollution sources in an industrial area, a UAV carrying the sample container flies to different monitoring points.

[0028] Based on the characteristics of pollutants emitted by different factories in the area, pneumatic heads (9) are used to collect the gases emitted by each factory into corresponding sampling bags. The sample bags are then taken back to the laboratory for detailed analysis, which accurately determines the pollution emissions of each factory and provides strong data support for developing targeted environmental protection measures.

[0029] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 The adsorption ring 11 is an iron ring, and the adsorption ring 11 is located on the bottom surface of the barrel.

[0030] By using an iron ring, the sample container can be attracted to the electromagnet inside the base 5. Only after the sample container is stably attracted to the base 5 can the risk of instability or even detachment of the air outlet 7 from the base 5 due to external wind be avoided. When the electromagnet is energized and generates a magnetic field, the iron attraction ring 11 will tightly adhere to the electromagnet, thus firmly fixing the sample container inside the base 5. In actual monitoring, even in windy weather, the sample container remains stable, and the air outlet 7 and the base 5 maintain a good connection, ensuring the accuracy and reliability of the monitoring data. Moreover, this iron ring attraction method is simple, easy to implement, and low in cost, while possessing high stability and practicality. It can meet the usage requirements of sample containers for UAV pollution source monitoring in various complex environments, providing a strong guarantee for accurately obtaining pollution source monitoring data.

[0031] In some embodiments of the sample retention container for monitoring pollution sources from unmanned aerial vehicles provided in this application, the vent 7 is a downward-facing flared opening, and the vent 7 extends to the outside of the container body.

[0032] The flared design facilitates efficient and easier docking with the air outlet 7 in the base 5. During docking, the downward-facing flared shape of the air outlet 7, extending to the outside of the container, makes the docking operation smoother. This design also helps to prevent air leakage during docking, ensuring the stability of gas transmission between the sample container and the base 5, thereby guaranteeing the accuracy and reliability of the monitoring data. In practical applications, this stable docking is crucial for accurately obtaining gas samples related to pollution sources, providing a solid data foundation for subsequent analysis and research.

[0033] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 and Figure 3 The lifting component 2 is a lifting head, and an annular groove for cooperating with the lifting is provided along the circumference of the lifting head.

[0034] Lifting heads are used for convenient lifting via drones. The selection of lifting heads can be tailored to specific needs to ensure effective gripping. When choosing a lifting head, its compatibility with the drone must be considered to ensure stable and safe operation during lifting. For example, the appropriate size and strength of the lifting head should be selected based on the drone model and load capacity. The design of the annular groove is also crucial; it ensures a tight fit with the lifting equipment, preventing swaying or detachment during lifting. In practical applications, the connection stability between different types of lifting equipment and the lifting head with the annular groove can be tested to further optimize the lifting scheme. For different pollution source monitoring scenarios, the material of the lifting head must also be considered to withstand the effects of corresponding environmental factors, such as chemical corrosion and high temperatures, to ensure the integrity and reliability of the sample container throughout the monitoring process.

[0035] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 and Figure 3 The barrel body includes an upper shell 1, a barrel body 4, and a lower shell 6; the lifting head is fixed on the upper shell 1; the adsorption ring 11 is fixed on the bottom surface of the lower shell 6; and the sampling bag is placed inside the barrel body 4.

[0036] The barrel needs to be lightweight and easy to disassemble and assemble for convenient inspection and replacement. Therefore, the upper shell 1, barrel body 4, and lower shell 6 can be made of lightweight and easy-to-process materials, such as specific plastic alloys. This material is not only lightweight but also possesses good strength and toughness, ensuring the stability of the barrel during use. In terms of design, the upper shell 1 and barrel body 4, and barrel body 4 and lower shell 6 can be connected using convenient methods such as snap-fit ​​or threads, making disassembly and assembly simple and quick. For example, by setting matching slots and blocks at the connection points, when disassembly is needed, simply pressing the corresponding parts allows for easy separation of the components. For the lifting head, its fixing method to the upper shell 1 can be a high-strength bolt connection, ensuring that it will not loosen or fall off during lifting.

[0037] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1Multiple connecting rods 3 connect the upper shell 1 and the lower shell 6. The barrel body 4 is made of PP film. To improve the stability of the relative position of the upper shell 1 and the lower shell 6, connecting rods 3 are connected between them, with both ends of the connecting rods 3 threaded onto the upper shell 1 and the lower shell 6, respectively. This connection method ensures that the upper shell 1 and the lower shell 6 fit tightly after assembly and are not easily loosened. In actual use, when the UAV carries the sample barrel for pollution source monitoring, this stable structure can effectively prevent the upper shell 1 and the lower shell 6 from separating due to factors such as vibration during flight, thus ensuring the sealing of the sample barrel. Even under complex environmental conditions, such as strong winds or airflow disturbances during low-altitude flight, the connecting rods 3 can still ensure the stability of the relative position of the upper shell 1 and the lower shell 6, thereby ensuring the safety and integrity of the sample inside the sample barrel. At the same time, the PP film barrel body 4 has a certain degree of flexibility and corrosion resistance, which can adapt to the sample preservation requirements of different pollution source environments. Combined with the stable upper shell 1 and lower shell 6 structure, it provides reliable sample retention protection for UAV pollution source monitoring.

[0038] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 Both the upper shell 1 and the lower shell 6 are detachably connected to the barrel body 4. The connection between the upper shell 1, lower shell 6, and barrel body 4 is achieved through threaded connections. The lower shell 6 has external threads on its outer circumference, and the barrel body 4 has corresponding internal threads. A tight connection and disassembly can be achieved by rotation. This design allows for convenient and quick replacement or cleaning of the upper shell 1 and lower shell 6 without affecting the normal use of the sample retention barrel for UAV pollution source monitoring. Furthermore, this detachable connection method ensures the overall sealing of the sample retention barrel structure, preventing sample leakage during monitoring and ensuring the accuracy and reliability of monitoring data. Simultaneously, the upper shell 1 and lower shell 6 are made of high-strength, wear-resistant, and chemically stable materials to meet the pollution source monitoring needs in different environments, ensuring long-term stable sample retention and providing high-quality samples for subsequent analysis and testing.

[0039] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 and Figure 2 The bottom of the lower shell 6 is provided with a power supply receiver 10, which is electrically connected to the solenoid valve 8. The power supply receiver 10 is used to receive the electrical energy transmitted by the sample container base 5 and to supply power to the solenoid valve 8.

[0040] The power receiver 10 receives electrical energy from the base 5 and transmits it to the solenoid valve 8. When energized, the solenoid valve 8 opens, allowing gas to escape. When de-energized, the gas path is cut off, preventing gas from escaping from the sampling bag. This coordination between the power receiver 10 and the solenoid valve 8 precisely controls gas escape, ensuring the accuracy and stability of gas sampling during UAV pollution source monitoring. In practical applications, when the UAV carrying the sampling bag arrives at the monitoring area, the power receiver 10 successfully receives electrical energy from the base 5, the solenoid valve 8 opens, and the polluted gas in the sampling bag is released according to preset requirements, completing the gas sample collection. After collection, the base 5 stops receiving power, the power receiver 10 receives no more power, the solenoid valve 8 is de-energized, and the gas path is cut off, preventing leakage or external interference of the collected gas in the sampling bag. The entire process was rigorous and orderly, providing reliable samples for subsequent analysis of the gas composition of the pollution source. This helped to accurately determine key information such as the type and concentration of the pollution source, thus providing strong data support for environmental protection and pollution source control.

[0041] For some embodiments of the sample retention bins for monitoring pollution sources from unmanned aerial vehicles provided in this application, please refer to... Figure 1 and Figure 2 The power supply receiver 10 is a wireless coil, and the projection of the power supply receiver 10 on the lower shell 6 is located outside the adsorption ring 11.

[0042] After the adsorption ring 11 is attracted to the electromagnet of the sample container base 5, the power receiving end 10 can receive electrical energy from the base 5. The power is received via a wireless coil to provide power to the relevant components of the sample container, ensuring its normal operation for pollution source monitoring and sample retention. This power supply method is not only convenient but also effectively avoids problems such as cable tangling associated with traditional wired power supplies. Once the adsorption ring 11 is firmly attracted to the sample container base 5, the power receiving end 10 stably receives electrical energy, enabling the monitoring equipment inside the sample container to begin operation. This allows for proper preservation and preliminary analysis of the collected pollution source samples, providing a reliable data foundation for subsequent, more precise monitoring work. This better supports environmental monitoring efforts and plays a crucial role in protecting the environment and understanding the status of pollution sources.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
