Description

Technical Field

[0001] This utility model relates to the field of liquid sampling technology, specifically to a remote-controlled liquid sampling device for chemical defense reconnaissance. Background Technology

[0002] In military reconnaissance and sampling missions, liquid sampling is often a very important part of the reconnaissance work. In conflict zones, there may be toxic substances, chemical warfare agents, radioactive materials or pathogens in the environment. These substances may be spread through water or soil and may even cause harm to the human body. Furthermore, the testing of liquid samples (such as water sources, rivers, lakes, groundwater, etc.) can also determine whether the water source is safe and suitable for drinking or use, or help to collect information about enemy activities.

[0003] However, existing military chemical reconnaissance and sampling missions basically require reconnaissance personnel to conduct extensive reconnaissance and exploration work on the mission site and its surrounding environment. However, conducting on-site reconnaissance work requires personnel to directly enter areas that may be contaminated, which brings with it high-risk and high-hazard issues, and may threaten the personal safety and lives of reconnaissance personnel. In addition, manual sampling missions have the problem of long time cycles, resulting in delayed information feedback.

[0004] Therefore, there is an urgent need for a remote liquid sampling device for chemical defense reconnaissance that can remotely control liquid sampling over long distances. Utility Model Content

[0005] To address the problems mentioned in the background section, a remote-controlled liquid sampling device for chemical defense reconnaissance is proposed. The technical solution adopted by this invention is as follows:

[0006] A remote-controlled liquid sampling device for chemical reconnaissance, mounted on an unmanned transport vehicle, includes a mounting component for fixing the liquid sampling device to the unmanned transport vehicle, a protective shell for protecting the liquid sampling device, a sampling bottle for storing liquid samples, a sampling component for collecting liquid samples over long distances, and a limit and power-off component for controlling the retrieval of the sampling tube.

[0007] The sampling assembly includes a first sampling tube for liquid sampling, a sampling motor and rotating roller for retrieving the first sampling tube, and a sampling pump for extracting liquid samples. The sampling assembly is equipped with a remote control signal receiving module.

[0008] In one embodiment, the protective housing is configured as a fully enclosed trapezoidal stack, the sampling component and the limiting power-off component are fixedly installed inside the protective housing, the mounting component is fixedly installed at the middle of the top of the protective housing, and the sampling bottle is disposed on one side of the top of the protective housing.

[0009] In one embodiment, the sampling assembly further includes a base and a sampling connector. The base is fixedly disposed at the bottom of the protective housing, a sampling motor is fixedly installed on one side of the top of the base, and a sampling connector is fixedly installed on the other side of the base.

[0010] In one embodiment, the sampling motor is fixedly connected to the rotating roller, and the other end of the rotating roller is rotatably connected to the sampling connector.

[0011] In one embodiment, the sampling assembly further includes a first sampling tube and a sampling filter element, one end of the first sampling tube is fixedly connected to the sampling connector, the first sampling tube is wound around the rotating roller, and the other end of the first sampling tube is fixedly connected to the sampling filter element.

[0012] In one embodiment, the sampling assembly further includes a second sampling tube and a third sampling tube. A sampling pump is provided on one side of the base inside the protective housing. The sampling pump and the sampling connector are fixedly connected to both ends of the second sampling tube, respectively. The sampling pump and the sampling bottle are fixedly connected to both ends of the third sampling tube, respectively.

[0013] In one embodiment, the limit power-off assembly includes a limit support plate and a limit switch, wherein the limit support plate is fixedly disposed at the bottom of the protective housing; and the limit switch is embedded in the bottom of the protective housing.

[0014] In one embodiment, the limiting power-off component further includes a limiting pressure plate, which is limited and disposed within the protective housing and the limiting support plate, and the bottom of the protective housing, the limiting support plate and the limiting pressure plate are all provided with limiting grooves.

[0015] In one embodiment, the limit power-off assembly further includes a contact lever, which is hinged to the bottom of the limit switch and contacts the limit pressure plate.

[0016] In one embodiment, the first sampling tube passes through the protective shell, the limiting plate, and the limiting groove of the limiting pressure plate.

[0017] The beneficial effects of this utility model's remote-controlled liquid sampling device for chemical defense reconnaissance are as follows:

[0018] 1. By setting up a sampling component inside the protective shell, and setting up a mounting device and sampling bottle on the top of the protective shell, the sampling component's sampling pump performs liquid sampling based on the sampling filter, the mounting device is attached to the unmanned transport equipment, and the collected liquid sample is stored in the sampling bottle. This achieves the effect of liquid sampling from a distance, solving the problems of hazards and delayed information feedback caused by the traditional liquid sampling method that requires on-site sampling by reconnaissance personnel.

[0019] 2. By setting a sampling motor, a rotating roller and a sampling connector on the base, and winding and storing the first sampling tube on the rotating roller, the sampling motor drives the rotating roller to control the opening and closing of the first sampling tube, thus solving the inconvenience caused by the inability to adjust the length of the first sampling tube when using a remote-controlled liquid sampling device.

[0020] 3. By incorporating a limit-off power-off component into the protective housing, when the first sampling tube is retracted to the point where the sampling filter contacts the limit pressure plate, continued retraction of the first sampling tube will cause the sampling filter to press against the limit pressure plate, thereby pressing the contact lever. The contact lever will then trigger the control signal of the limit switch, thus stopping the operation of the sampling motor. This solves the problem of damage to device components caused by excessive retraction of the first sampling tube. Attached Figure Description

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figure 1-5 As shown, a remote-controlled liquid sampling device for chemical reconnaissance is mounted on an unmanned transport vehicle and includes a mounting component 1 for fixing the liquid sampling device to the unmanned transport vehicle, a protective shell 2 for protecting the liquid sampling device, a sampling bottle 3 for storing liquid samples, a sampling component 4 for collecting liquid samples over long distances, and a limit power-off component 5 for controlling the recovery of the sampling tube.

[0029] The sampling assembly 4 includes a first sampling tube 404 for liquid sampling, a sampling motor 402 and a rotating roller 403 for recovering the first sampling tube 404, and a sampling pump 407 for extracting liquid samples. The sampling assembly 4 is equipped with a remote control signal receiving module.

[0030] In this embodiment, the liquid sampling device is deployed on the unmanned transport device based on the mounting component 1. The first sampling tube 404 is released by the sampling motor 402 and the rotating roller 403 of the sampling component 4, and the sampling pump 407 is controlled by the remote control signal receiving module to sample the liquid sample. The collected liquid sample is stored in the sampling bottle 3. After the sampling is completed, the first sampling tube 404 is retrieved by controlling the sampling motor 402, and the retrieval action of the first sampling tube 404 is stopped by controlling the sampling motor 402 through the limit power-off component 5.

[0031] In one embodiment, the protective housing 2 is configured as a fully enclosed trapezoidal stack, the sampling component 4 and the limiting power-off component 5 are fixedly installed inside the protective housing 2, the mounting component 1 is fixedly installed at the middle of the top of the protective housing 2, and the sampling bottle 3 is disposed on one side of the top of the protective housing 2.

[0032] In this embodiment, the protective shell 2 is used to protect the internal sampling component 4 and the limiting power-off component 5, and the mounting component 1 is used to fix the liquid sampling device to the unmanned transport equipment.

[0033] In one embodiment, the sampling assembly 4 further includes a base 401 and a sampling connector 405. The base 401 is fixedly disposed at the bottom of the protective housing 2. A sampling motor 402 is fixedly installed on one side of the top of the base 401, and a sampling connector 405 is fixedly installed on the other side of the base 401.

[0034] In this embodiment, the base 401 is used to fix the sampling connector 405 and the sampling motor 402, and to provide support for the sampling assembly 4; the sampling connector 405 is a fixedly installed component with rotatable internal connectors.

[0035] In one embodiment, the sampling motor 402 is fixedly connected to the rotating roller 403, and the other end of the rotating roller 403 is rotatably connected to the sampling connector 405.

[0036] In this embodiment, the sampling motor 402 can drive the rotating roller 403 to rotate synchronously; and the sampling connector 405 is rotatably connected to the rotating roller 403, so that when the sampling motor 402 drives the rotating roller 403 to rotate, the sampling connector 405 remains fixed.

[0037] In one embodiment, the sampling assembly 4 further includes a first sampling tube 404 and a sampling filter 408. One end of the first sampling tube 404 is fixedly connected to the sampling connector 405, the first sampling tube 404 is wound around the rotating roller 403, and the other end of the first sampling tube 404 is fixedly connected to the sampling filter 408.

[0038] In this embodiment, the middle end of the first sampling tube 404 is wound around the rotating roller 403 for storage. One end of the first sampling tube 404 passes through the central axis of the rotating roller 403 and is fixedly connected to the rotatable part inside the sampling connector 405. This allows the first sampling tube 404 wound around the rotating roller 403 to rotate synchronously with the rotating roller 403. This ensures that the first sampling tube 404 is wound around the rotating roller 403 for storage when the rotating roller 403 rotates, and avoids the first sampling tube 404 from bending when the rotating roller 403 retracts the first sampling tube 404. The sampling filter element 408 is provided with a filter screen, which can filter out impurities in the liquid before sampling.

[0039] In one embodiment, the sampling assembly 4 further includes a second sampling tube 406 and a third sampling tube 409. A sampling pump 407 is provided on one side of the base 401 inside the protective housing 2. The two ends of the second sampling tube 406 are respectively fixedly connected to the sampling pump 407 and the sampling connector 405. The two ends of the third sampling tube 409 are respectively fixedly connected to the sampling pump 407 and the sampling bottle 3.

[0040] In this embodiment, the first sampling tube 404 is used to adjust the extension length according to the actual situation for sample collection, the second sampling tube 406 is used to transfer the collected liquid sample to the sampling pump 407, and the third sampling tube 409 is used to transfer the collected liquid sample from the sampling pump 407 to the sampling bottle 3 for storage.

[0041] In one embodiment, the limit power-off component 5 includes a limit plate 501 and a limit switch 502. The limit plate 501 is fixedly disposed at the bottom of the protective housing 2; the limit switch 502 is embedded in the bottom of the protective housing 2.

[0042] In this embodiment, the limit switch 502 can be used to control the stopping of the sampling motor 402.

[0043] In one embodiment, the limiting power-off component 5 further includes a limiting pressure plate 503, which is limited and disposed within the protective housing 2 and the limiting support plate 501, and the bottom of the protective housing 2, the limiting support plate 501 and the limiting pressure plate 503 are all provided with limiting grooves.

[0044] In this embodiment, when the sampling filter 408 comes into contact with the limiting pressure plate 503 based on the recovery of the first sampling tube 404, the limiting pressure plate 503 will rise synchronously with the rise of the sampling filter 408.

[0045] In one embodiment, the limit power-off assembly 5 further includes a contact lever 504, which is hinged to the bottom of the limit switch 502 and contacts the limit pressure plate 503.

[0046] In this embodiment, when the contact paddle 504 is pressed by the limiting pressure plate 503, it will activate the limit switch 502, thereby triggering the limit switch 502 to send an electrical signal to the sampling motor 402.

[0047] In one embodiment, the first sampling tube 404 penetrates the limiting groove of the protective shell 2, the limiting support plate 501, and the limiting pressure plate 503.

[0048] The specific implementation method of the remote-controlled liquid sampling device for chemical defense reconnaissance of this utility model is as follows:

[0049] First, the liquid sampling device is deployed on the unmanned transport vehicle based on the mounting component 1. When the liquid sampling device arrives at the mission location, the reconnaissance personnel remotely drive the sampling motor 402 of the sampling component 4 via the remote signal receiving module, causing the rotating roller 403 to rotate synchronously. This releases the first sampling tube 404 and the sampling filter 408 into the liquid and drives the sampling pump 407 to perform sampling. The collected liquid sample is then transferred to the sampling pump 407 through the sampling filter 408, the first sampling tube 404, the sampling connector 405, and the second sampling tube 406, and then transferred to the sampling bottle 3 for storage through the third sampling tube 409. After sampling is completed, the scout remotely stops the sampling pump 407 and reverses the sampling motor 402. The rotating roller 403, under the action of the sampling motor 402, reverses to retract the first sampling tube 404. When the first sampling tube 404 is retracted to contact the limiting pressure plate 503, continuing to retract the first sampling tube 404 will cause the limiting pressure plate 503 to press the contact lever 504. At this time, the contact lever 504 will activate the limit switch 502, thereby triggering the limit switch 502 to send an electrical signal to stop the sampling motor 402, thus completing the retrieval of the first sampling tube 404. Subsequently, the liquid sampling device can be retrieved using unmanned transport equipment.

[0050] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
