Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampler technology, specifically relating to an automatic sampler for petroleum in water based on a drone. Background Technology
[0002] Oil samplers have a wide range of applications, including marine monitoring. Their core purpose is to ensure that the collected samples accurately reflect the overall quality, composition, and characteristics of the oil.
[0003] Traditional petroleum sampling primarily involves shoreline sampling, bridge-mounted sampling, and manual boat sampling. Shoreline sampling is affected by water depth and sediment, making it difficult to collect representative samples and easily disturbing the sediment, thus affecting analytical data. Bridge-mounted sampling is limited by the bridge's location, making it impossible to effectively collect water samples at fixed points and accurately sample at water depths. Manual boat sampling suffers from significant sample contamination due to mechanical vibration causing water level fluctuations and pollution from boat discharge. Utility Model Content
[0004] The purpose of this invention is to provide an automatic water sampler for petroleum products based on unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art, such as monitoring data bias, underreporting of pollution concentration, insufficient sampling representativeness, inability to reflect spatial heterogeneity, difficulty in tracing the source and assessing risk, and limited applicability of standard methods.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic water petroleum sampler based on a drone, comprising an installation component; the installation component is fixed to the bottom of the drone; a sampling component connected to the installation component, wherein the sampling component includes: a sampling tank, which is a hollow tube structure with openings at both ends; two partitions are provided inside the sampling tank, the partitions being symmetrically distributed around the center of the sampling tank; a positioning module is also provided outside the sampling tank, the positioning module being wirelessly connected to the drone, and during descent, the drone controls the motor to achieve descent to a designated position; a drive component is located in the middle of the two partitions; an opening and closing component is located at both ends of the sampling tank, the opening and closing component closing both ends of the sampling tank through the drive component, and the opening and closing component separating from both ends of the sampling tank when not driven by the drive component, the state of separation being the state before water entry and sampling completion, and after sampling is completed, the opening and closing component is controlled by the drive component to seal both ends of the sampling tank.
[0006] Preferably, a lithium battery ring is also provided inside the sampling container. The lithium battery ring is located between the partitions and is arranged concentrically with the sampling container. A control switch is also installed on the side of the lithium battery ring, and the drive assembly is located inside the lithium battery ring.
[0007] Preferably, the drive assembly includes a fixed iron core and a coil wound around the outside of the fixed iron core. Mounting rods are also fixed at both ends of the fixed iron core and are fixedly connected to the partition plate to realize the installation of the entire drive assembly. The coil is electrically connected to the control switch. When the lithium battery ring energizes the coil, the fixed iron core generates magnetic force and attracts the opening and closing assembly, thereby realizing the opening and closing of both ends of the sampling can. The control switch is wirelessly connected to the drone. The drone can be used to open and close the control switch to start the drive assembly at a designated location.
[0008] Preferably, the opening and closing assembly includes a connecting rod that passes through the partition, one end of which is fixed with a closing cover, and the other end of which is fixed with a metal plate, the metal plate being magnetically connected to the end of the fixed iron core.
[0009] Preferably, a spring is also sleeved on the connecting rod. The spring is located between the metal plate and the partition. When water enters, the spring is in its initial state. At this time, the closed cover is outside the sampling tank, and the water can enter the sampling tank. After sampling is completed, the coil generates magnetic force and attracts the metal plate. At this time, the spring is stretched, thereby pulling the closed cover back to close the sampling tank.
[0010] Preferably, a sealing bearing is provided between the partition and the connecting rod to prevent water from entering between the partitions. A strip groove is provided on the top of the sampling tank, and a charging port extending into the strip groove is provided on the top of the lithium battery ring. A sealing strip embedded in the strip groove is also provided on the top of the sampling tank to seal the charging port.
[0011] Preferably, the mounting assembly includes a mounting bracket fixed to the bottom of the drone, and a motor disposed on one side of the mounting bracket. The output end of the motor is connected to a shaft located inside the mounting bracket. A connecting wire is wound on the shaft, and the connecting wire is fixed to the middle position of the top of the sampling tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The sampler in this invention can be used in conjunction with drones, is not limited by sampling space, allows for flexible deployment, eliminates monitoring blind spots, and can automatically close the inlet after collecting water samples at a specified depth to prevent infection and water pollution, ensuring accurate experimental data. It can also collect parallel samples simultaneously, ensuring quality control. Attached Figure Description
