Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned biological sampling, and in particular relates to an unmanned biological sampling device. Background Art

[0002] Biological sampling is a technology that is widely used in fields such as biological research. For example, in the field of biological research, by collecting biological samples left by animals in the environment, it is possible to judge the physiological characteristics of animals. By detecting and detecting animals, it is possible to judge the movement trajectory of animals, the number of animals, the size of the population and other information, so as to guide biological research.

[0003] In actual work, it is found that in certain specific situations, it is more suitable to conduct sampling of organisms remotely. For example, in areas with harsh geographical environments, where it is difficult for people to walk, or in complex environments such as toxic environments, remote sampling is not only safer, but also has a certain degree of confidentiality. Remote sampling effectively avoids the risk of workers entering dangerous environments.

[0004] However, during the collection process, especially when collecting air samples, it was found that current drones are difficult to collect effectively. Specifically, since gas samples are different from water samples and soil samples that are easy to collect, the gas samples are pumped into a storage device during the collection process, and the performance of most current drones is not able to effectively complete the collection work.

[0005] Current drones perform relatively well when collecting easy-to-collect samples such as water and soil, but have difficulty collecting gases. The fundamental reason is the particularity of gas samples. Utility Model Content

[0039] Example 1

[0040] like Figure 1-4 As shown, an unmanned biological sampling device includes a drone body 1, wherein the drone body 1 is a conventional drone disclosed in the prior art, and the drone body 1 mainly completes the flight by pressing a flight mechanism on the drone body 1, which is specifically the same as the existing drone, and the flight mechanism includes a plurality of propellers 2 installed at the top of the body; and the propeller 2 is equipped with a motor, which drives the propeller to rotate and takes off by airflow. Those skilled in the art can know the specific structure and working principle of the drone body 1 disclosed in the utility model by consulting a technical manual or dictionary.

[0041] Just like existing drones that can walk on the ground, a walking mechanism is installed at the bottom of the drone body 1 according to the existing walking method of drones. Specifically, it is the same as the crawler walking structure used by existing drones. Track wheels 7 and crawler tracks 8 are installed at the bottom of the drone body 1. During operation, the drone walks through the cooperation of track wheels 7 and crawler tracks 8, thereby meeting the needs of walking on muddy roads.

[0042] In order to realize the collection of gas samples under specific environment, the utility model makes the following improvements:

[0043] The top of the drone body 1 is detachably assembled and connected with an aerosol collection mechanism (specifically, the drone body 1 includes a body portion, and the aerosol collection mechanism is installed at the top position of the body portion); specifically, the gas in the atmosphere (the gas in the atmosphere contains a large amount of sol particles, and the sol particles often exist in the form of sol, and the sol is a package formed by gas, water, solid, etc.) is collected through the aerosol collection mechanism.

[0044] The aerosol collection mechanism includes a sampler 15, and the structure of the sampler 15 is as follows: the sampler 15 includes a cavity and a cover 16 detachably assembled and connected to the top of the cavity; the sampler 15 is connected to a bend 14 (the shape of the bend 14 is L-shaped), and the bend 14 is connected to the cover 16. Specifically, the upper end of the sampler 15 is integrally formed with a boss protruding from the inside; the cover 16 is assembled and connected to the top of the boss.

[0045] The specific assembly method is a conventional assembly method disclosed in the prior art, such as threaded connection or plug-in connection.

[0046] At the same time, a filter screen is arranged on the top of the boss, and when the cover 16 is assembled and connected to the top of the boss, the filter screen is positioned and clamped between the cover 16 and the boss. The function of the filter screen is to filter dust in the air.

[0047] The upper end of the above-mentioned curved pipe 14 is connected to a sol sample storage tube 13 for storing sol samples, and a hopper is integrally formed on the top of the sol sample storage tube 13 (for increasing the contact surface with the air to facilitate air entry); specifically: the curved pipe 14 is connected to the upper end of the sol sample storage tube 13.

[0048] At the same time, the sampler 15 is connected to a negative pressure suction mechanism, which includes a shell 18 connected to the sampler 15, and a negative pressure fan 19 is installed in the shell 18 (the negative pressure fan 19 is a conventional fan disclosed in the prior art, which includes a fan motor installed in the shell and fan blades installed on the fan motor), and an exhaust hole is connected to the shell.

[0049] During operation, when the negative pressure fan 19 is working, driven by the fan blades, the air flow is discharged from the exhaust hole and forms a negative pressure. The atmosphere and the sol samples in the atmosphere follow the gas into the sol sample storage tube 13 for storage, and part of the sample enters the cavity of the sampler 15, thereby completing the collection.

[0050] The above method can realize the collection of difficult-to-collect gas samples by sending the working equipment into a special and complex geographical environment in a simple and effective way by utilizing the remote operation feature of the human-machine interface. The above method is not only highly efficient in collection, but also in the process of collection, the sampler 15, the curved pipe 14, the sol sample tube 13, the negative pressure fan 19 and other components can be used to easily collect samples in the air.

[0051] Example 2

[0052] like Figure 1 -As described above, based on the structure of Example 1, the present embodiment adopts a detachable assembly connection between the drone body 1 and the aerosol collection mechanism by a connecting piece; the connecting piece includes a connecting seat body 9 fixedly connected to the drone body 1, and the bottom of the sol sample tube 13 is fixedly connected to a snap-in seat 11 adapted to the seat body; a plurality of snap-in protrusions 12 are integrally formed on the snap-in seat 11, and an annular snap-in groove with a limited position of the snap-in protrusions 12 is provided on the connecting seat body 9, and a plurality of snap-in sockets 10 adapted to the snap-in protrusions 12 are connected to the top of the connecting seat body 9, and when the snap-in protrusions 12 are snapped into the annular snap-in groove along the snap-in sockets 10, the connecting seat body 9 is rotated until the snap-in protrusions 12 are offset from the snap-in sockets 10 and are positioned in the annular snap-in groove.

[0053] The above method makes it easy to disassemble and assemble the drone body 1 and the aerosol collection mechanism in a detachable connection manner.

Among them, the infrared life detector is a conventional infrared life detector 6 disclosed in the prior art, and it is installed on the drone body 1 in the same way as the infrared life detector on the existing drone.

[0056] Example 3

[0057] like Figure 1 -As described above, this embodiment is based on the structure of embodiment 1. In order to meet the sampling of solid samples such as soil during operation, a mechanical arm 4 is installed on the drone body 1, which is the same as the existing drones with sampling functions. During the sampling process, the mechanical arm 4 is used to clamp the sample and put it into the sampler 5 installed on the drone body 1.

[0058] Similar to existing drones, the drone body 1 operates through a removable power source such as a battery installed inside the drone body, and the propellers, negative pressure fans, track wheels and other components on the drone body all operate in accordance with the existing drone working methods.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
