[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0026] like Figure 1 As shown, a marine UAV sampling device comprises a body 1, a winch 2 is arranged inside the body 1, a traction rope 3 is wound around the winch 2, a power mechanism 4 is arranged at the other end of the traction rope 3, and a sampling assembly 5 is arranged at the bottom of the power mechanism 4; wherein, the sampling assembly 5 comprises a porous sampler shell 16 and a porous sampler liner 15, the porous sampler shell 16 and the porous sampler liner 15 are linked by a bracket 14, the bracket 14 is used to drive the porous sampler liner 15 to rotate, so that the sampling assembly 5 is closed or opened, and the power mechanism 4 comprises an upper filter cover 6, the upper filter cover 6 is fixedly connected to the second output 7 shaft, and the upper filter cover 6 is tightly fitted with the lower filter cover 8.

[0027] In this embodiment, when collecting normally, the winch 2 is controlled to rotate to extend the traction rope 3, and the sampling assembly 5 and the power mechanism 4 sink to the seabed and contact the seabed. By controlling the body 1 to fly back and forth, the dual-axis motor 9 is started to allow seawater and silt to pass through the upper filter cover 6 and the lower filter cover 8 and enter the sampling assembly 5. The seawater flows out of the porous sampler shell 16 through the porous sampler liner 15, while the silt will remain in the porous sampler liner 15. When you want to collect a single sample or a complete sample, you can control the power mechanism 4 to rotate the porous sampler liner 15, thereby controlling the sampling assembly 5 to close or open, so that you can collect a single sample or a complete sample. The entire process does not require the drone to return, which can effectively improve the efficiency of collecting samples.

[0028] like Figure 5 As shown, the power mechanism 4 includes an upper filter cover 6 and a lower filter cover 8, a dual-axis motor 9 is fixed inside the lower filter cover 8, the dual-axis motor 9 is fixedly connected to a cleaning brush 11 through a first output shaft 10, an upper impeller 12 is arranged below the cleaning brush 11, and the upper impeller 12 is fixed at the bottom of the first output shaft 10.

[0029] In the above method, when the sampling begins, the body 1 flies back and forth, and the dual-axis motor 9 is controlled to start working, so that the first output shaft 10 and the second output shaft 7 start to rotate, and the second output shaft 7 drives the upper filter cover 6 to rotate. The rotation of the upper filter cover 6 can clear a part of the blockage. At the same time, the first output shaft 10 drives the cleaning brush 11 and the upper impeller 12 to start rotating, wherein the rotation of the upper impeller 12 can allow the sample to quickly enter the lower filter cover 8, and the rotation of the cleaning brush 11 can allow the bristles on the cleaning brush 11 to clean the other part of the sample that is blocked on the lower filter cover. It should be noted that the bristles are hard bristles.

[0030] like Figure 3 As shown, the through holes of the upper filter cover 6 and the lower filter cover 8 are adapted to each other, staggered with each other in the initial state, and the upper filter cover 6 and the lower filter cover 8 are tightly fitted through damping.

[0031] In the above method, when the sample collection starts, the dual-axis motor 9 works, the upper filter cover 6 continues to rotate, and the sample is sucked into the lower filter cover 8 from the through hole. When the sample is collected, the dual-axis motor 9 stops working, the upper filter cover 6 and the lower filter cover 8 return to the initial position, and the power mechanism 4 is closed, so that the collected sample cannot contact the external environment.

[0032] like Figure 2 As shown, the power mechanism 4 is fixedly connected to the sampling assembly 5 via a locking member.

[0033] In the above manner, the locking member can be a bolt, a buckle or other components that can achieve a detachable fixing structure. A buckle is used here, and the installed locking member can quickly disassemble or combine the power mechanism 4 and the sampling component 5, thereby improving the collection efficiency.

[0034] like Figure 4 As shown, the porous sampler liner 15 is arranged inside the porous sampler shell 16, and the porous sampler liner 15 and the porous sampler shell 16 are tightly fitted through damping, the bracket 14 passes through the upper end of the porous sampler liner 15 and is fixedly connected thereto, and a lower impeller 13 is fixedly connected to the middle position of the bracket 14, and the rotation of the lower impeller 13 can drive the porous sampler liner 15 to rotate through the bracket 14.

[0035] In the above manner, when sampling begins, if only mud and sand are taken as the sample, the cement mixture driven by the rotation of the upper impeller 12 flows into the interior of the sampling component 5, and the flow of water drives the lower impeller 13 to rotate, so that the porous sampler liner 15 is driven by the lower impeller 13 and the bracket 14 to rotate, so that the sampling component 5 is opened, and the seawater in the cement mixture can flow out from the porous sampler housing 16. During this process, the power mechanism 4 is always working. If a complete sample is taken, the power mechanism 4 is turned off during the ascent, so that the power mechanism 4 returns to the initial position, the power mechanism 4 is turned off, the lower impeller 13 does not rotate, and the porous sampler liner 15 returns to the initial position under the action of attraction, so that the sampling component 5 is closed, thereby obtaining a complete sample.

[0036] like Figure 4 As shown, in the initial state, the through holes of the porous sampler housing 16 and the porous sampler liner 15 are matched and staggered with each other.

[0037] In the above manner, the hole sizes of the porous sampler shell 16 and the porous sampler liner 15 are one-to-one corresponding, and the sampling component 5 is in a closed state in the initial state.

[0038] like Figure 6 As shown, two grooves are opened on both sides of the upper end of the porous sampler housing 16, and the bracket 14 is placed in the grooves. A magnet 17 is placed in each of the two grooves. The two magnets 17 are placed opposite to each other on the sides of the two grooves, and a magnet 17 is fixedly connected at each end of the bracket 14, which attracts the magnets 17 in the grooves with opposite sexes.

[0039] In the above manner, the two ends of the bracket 14 are placed in two grooves. When the lower impeller 13 is not subjected to force, the two magnets 17 are attracted to the two magnets 17 on the bracket 14 respectively, and the sampling component 5 is closed. At this time, all structures are in the initial position. When the lower impeller 13 is acted upon by the power mechanism 4, the water flow causes the bracket 14 to rotate, thereby separating the bracket 14 from the magnet 17, and the sampling component 5 is opened.

[0040] The working principle of the utility model is as follows: when collecting normally, the winch 2 is controlled to rotate, so that the traction rope 3 is extended, the sampling assembly 5 and the power mechanism 4 sink to the seabed and contact the seabed, and the body 1 is controlled to fly back and forth, and the dual-axis motor 9 is controlled to start working, so that the first output shaft 10 and the second output shaft 7 start to rotate, and the first output shaft 10 rotates and drives the cleaning brush 11 and the upper impeller 12 to start rotating, and the cleaning brush 11 cleans a part of the blockage on the lower filter cover 8 and the upper filter cover 6, and the second output shaft 7 rotates to drive the upper filter cover 6 to rotate, so that another part of the blockage is cleaned, and the upper impeller 12 rotates to make the sample pass through the power mechanism 4 into the sampling assembly 5, and the upper impeller 1 The water flow driven by the rotation makes the lower impeller 13 rotate, thereby driving the bracket 14 and the porous sampler liner 15 to rotate, and the bracket 14 is away from the magnet 17, so that the sampling component 5 is opened, and the seawater flows out from the porous sampler shell 16, and the sample is retained in the porous sampler liner 15. If the sediment sample is collected, the power mechanism 4 will continue to work. If the complete sample is to be taken, the power mechanism 4 is closed during the rise, and the power mechanism 4 returns to the initial position, so that the power mechanism 4 is closed, resulting in the sampling component 5 being attracted by the magnet 17, so that the sampling component 5 is restored to the initial position, and the sample is completely retained in the porous sampler liner 15, thereby completing a series of work.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
