Description

Technical Field

[0001] This utility model relates to the field of water stratification measurement equipment, and in particular to an unmanned vessel for water stratification measurement. Background Technology

[0002] According to the patent document with publication number CN222373080U, the patent document describes a method where a second motor drives a support plate to rotate, thereby loosening the water pipe and allowing it to be lowered into the water body by a counterweight. Water is then drawn from the water body through a sampling pump and the water pipe, passing through a water bucket into the sampling tank. A first motor drives a rotating shaft to rotate a limiting device, which then moves the sampling tank filled with water away. The rotating sampling tank's seal engages with an arc-shaped toothed plate, causing the seal to rotate and seal the opening between the water bucket and the sampling tank. The water is filtered through the filter holes on the counterweight to prevent impurities from entering the sampling pump.

[0003] The patent document states that during the process of the unmanned vessel moving to the sampling water location, the presence of abundant aquatic plants or debris in some water areas caused the propeller of the unmanned vessel to become entangled and obstructed, affecting the movement and operation of the drone. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8 As shown, an unmanned surface vessel for water stratification measurement includes a hull 1, a sampling mechanism 3 located on one side of the top of the hull 1, propellers 2 fixed on both the front and rear sides of the bottom of the hull 1, and a cleaning mechanism 4 located on one side of the two propellers 2.

[0029] In this embodiment: the cleaning mechanism 4 includes a sliding plate 401, which is slidably connected to one side of the hull 1. A rotating shaft 402 is rotatably connected to one side of the sliding plate 401. A sliding groove that mates with the sliding plate 401 is provided on one side of the hull 1. A second motor is fixedly installed at the input end of the rotating shaft 402. A gear 403 is fixedly installed on the outside of the rotating shaft 402. A rack 404 that mates with the gear 403 is fixedly installed on one side of the hull 1. A support plate 405 is fixedly installed on one side of the sliding plate 401. The gear 403 is located on the sliding plate 401. Between the moving plate 401 and the support plate 405, a rotating plate 406 is fixed to one end of the rotating shaft 402 that passes through the support plate 405. A rotating rod 407 is fixed to one edge of the rotating plate 406. A connecting ring 408 is sleeved on the rotating rod 407. Sliding rods 409 are fixed to both the front and rear sides of the connecting ring 408. Both sliding rods 409 are slidably connected to one side of the support plate 405. Two limiting frames for cooperating with the sliding rods 409 are fixed to one side of the support plate 405. Filter screens 4 are fixed to one side of each of the two propellers 2. 11. Scrapers 410 are fixed to the bottom of the two sliding rods 409 at their far ends. The two scrapers 410 are located on one side of the two filter screens 411, and the sharpest points of the two scrapers 410 coincide with the plane of one side of the two filter screens 411. The two filter screens 411 intercept water plants and debris near the two propellers 2. The second motor drives the rotating shaft 402 to drive the gear 403 to rotate counterclockwise. The gear 403 rolls down along the rack 404, thereby driving the sliding plate 401 on the hull 1. The sliding groove moves downward, thereby causing the support plate 405, the two sliding rods 409, and the two scrapers 410 to move downward. The two scrapers 410 scrape off the aquatic plants and debris on the two filter screens 411 respectively. During this process, the rotating shaft 402 drives the rotating plate 406 and the rotating rod 407 to rotate counterclockwise, which in turn drives the connecting ring 408 to move back and forth on both sides, thereby driving the two sliding rods 409 and the two scrapers 410 to move back and forth on both sides, further scraping off the aquatic plants and debris on the two filter screens 411.

[0030] In this embodiment: the sampling mechanism 3 includes a rotating roller 301, a first motor 303 is fixedly installed at the input end of the rotating roller 301, the rotating roller 301 is rotatably connected to the top of the hull 1, a first sampling tube 302 is wound around the outside of the rotating roller 301, a water pump 304 is fixedly installed at the water inlet end of the first sampling tube 302, a second sampling tube 305 is fixedly installed through the rotating roller 301 at the water outlet end of the first sampling tube 302, a plurality of sampling cylinders 307 are fixedly installed at the water outlet end of the second sampling tube 305, and a valve 306 is fixedly installed at one end of the second sampling tube 305 near the plurality of sampling cylinders 307. The plurality of sampling cylinders 307 are all located at the top of the hull 1. The first motor 303 drives the rotating roller 301 to rotate to control the length of the first sampling tube 302 in the water. The water pump 304 draws water samples into the first sampling tube 302 and into the sampling cylinders 307 from the second sampling tube 305. The valve 306 controls which sampling cylinder 307 the water sample in the second sampling tube 305 enters.

[0031] Working principle: As the vessel 1 moves to the water area to be sampled, two filter screens 411 intercept aquatic plants and debris near the two propellers 2. The second motor drives the shaft 402 to rotate the gear 403 counterclockwise. The gear 403 rolls downward along the rack 404, which in turn moves the sliding plate 401 downward within the sliding groove of the vessel 1. This, in turn, moves the support plate 405, the two sliding rods 409, and the two scrapers 410 downward. The two scrapers 410 scrape off the aquatic plants and debris from the two filter screens 411. During this process... The rotating shaft 402 drives the rotating plate 406 and the rotating rod 407 to rotate counterclockwise. When the rotating rod 407 turns from the rear to the front, it drives the connecting ring 408 to move forward. When the rotating rod 407 turns from the front to the rear, it drives the connecting ring 408 to move backward, thereby driving the connecting ring 408 to move back and forth along the front and rear sides. This drives the two sliding rods 409 and the two scrapers 410 to move back and forth along the front and rear sides. After the water plants are scraped off, the second motor drives the rotating shaft 402 to rotate clockwise, driving the support plate 405 and the two scrapers 410 to reset. This is how the cleaning is done periodically.

[0032] After the hull 1 reaches the target position, according to the sampling requirements, the first motor 303 drives the rotating roller 301 to rotate, so that the first sampling tube 302 enters the water and reaches the specified depth. The water pump 304 draws the water sample into the first sampling tube 302 and into the sampling cylinder 307 from the second sampling tube 305. The valve 306 controls the water sample in the second sampling tube 305 to enter the corresponding sampling cylinder 307 to continue sampling.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
