DETAILED DESCRIPTION

[0033] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0034] With reference to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the present application provides an embodiment: a practical device for collecting sediment samples in rivers and lakes with a water depth of 10 meters or less, comprising a fixed block 1 and a waterproof shell 7, the outer side of the fixed block 1 is provided with a plurality of solar components, the inner side of each waterproof shell 7 is provided with a lifting assembly, and the bottom of one of the waterproof shells 7 is fixedly connected with a hollow block 10, and the bottom of the hollow block 10 is provided with a grabbing assembly.

[0035] The grabbing assembly comprises a plurality of electric push rods 20, each electric push rod 20 is rotatably connected to the inner side of the hollow block 10, the end of each electric push rod 20 is rotatably connected with a connecting frame 12, the end of each connecting frame 12 is rotatably connected to the inner side of the hollow block 10, and the inner side of the end of each connecting frame 12 is fixedly connected with a collecting hopper block 11. The electric push rod 20 is elongated and contracted, which drives the connecting frame 12 rotatably connected thereto to rotate around the connecting point with the hollow block 10. When the collecting hopper block 11 is inserted into the sediment, the electric push rod 20 is elongated, which drives the connecting frame 12 to rotate reversely, so that the collecting hopper block 11 is closed, thereby grabbing the sediment sample.

[0036] With reference to Figure 2 , Figure 3 and Figure 4The lifting assembly comprises a connecting box 15 fixedly connected to the inner side of the waterproof shell 7, a connecting rod 19 rotatably connected to the inner side of the connecting box 15, a driving motor 17 fixedly connected to the inner side of the end of the waterproof shell 7, and the output end of the driving motor 17 fixedly connected to the inner side of the end of the connecting rod 19. The outer sides of the two connecting rods 19 are respectively provided with a rope 8 and a rope 18. The end of the rope 8 is fixedly connected with a sinker 9, and the rope 18 is slidably connected to the inner side of the middle of the hollow block 10. The multiple ends of the rope 18 are respectively fixedly connected to the inner sides of the connecting frame 12 and the collecting bucket block 11. The bottom of the sinker 9 is fixedly connected to the outer side of one of the waterproof shells 7. The driving motor 17 is started to drive the connecting rod 19 to rotate. The rope 8 is wound around one of the connecting rods 19, and the sinker 9 connected to the end of the rope 8 will descend with the unwinding of the rope 8, and the sinker 9 plays a role of stabilizing device and auxiliary descending. The rope 18 is wound around the other connecting rod 19, and one end of the rope 18 is slidably connected to the inner side of the middle of the hollow block 10, and the other end is connected to the inner sides of the connecting frame 12 and the collecting bucket block 11. With the rotation of the connecting rod 19, the rope 18 is unwound, so that the hollow block 10 and the grabbing and clamping assembly descend to the bottom of the water.

[0037] With reference to Figure 1 and Figure 2 The solar assembly comprises an electric push rod 14 fixedly connected to the inner side of the fixed block 1, and a sealing frame 13 rotatably connected to the end of the electric push rod 14 and rotatably connected to the outer side of the fixed block 1. The electric push rod 14 can be telescopic, and the angle of the sealing frame 13 can be adjusted by changing the length of the electric push rod 14. The angle of the solar panel 3 can be adjusted by the electric push rod 14, so that it can face the sun directly, thereby maximizing the absorption of solar energy and converting it into electrical energy to power other components of the device. The solar assembly further comprises a plurality of solar panels 3 fixedly connected to the inner side of the sealing frame 13, and a plurality of waterproof strips 4 fixedly connected to the outer side of the end of the solar panels 3. The waterproof strips 4 on the outer side of the end of the solar panels 3 play a waterproof role to protect the solar panels 3.

[0038] With reference to Figure 1 and Figure 2 A plurality of supports 5 are fixedly connected to the outer side of the fixed block 1, and a plurality of floating blocks 6 are fixedly connected to the ends of the supports 5. The buoyancy of the floating blocks 6 enables the entire device to float stably on the water surface. A warning light 2 is fixedly connected to the top of the fixed block 1. The warning light 2 can emit warning signals at night or in poor light conditions to alert passing ships or personnel, thereby avoiding collisions with the device and ensuring the safety and normal working environment of the device. One of the waterproof shells 7 is provided with a propeller 16.

[0039] Working principle: when the sediment sample is needed to be collected, the driving motor 17 is started to drive the connecting rod 19 to rotate. Since the rope 18 is connected to the sinker 9 and the rope 18 is connected to the hollow block 10, the grab assembly and the sinker 9 will descend with the rotation of the connecting rod 19, and the device will dive into the water.

[0040] When the device dives to the bottom of the water, the grab assembly starts to work. The electric push rod 20 is extended and contracted to drive the connecting frame 12 to rotate around the rotating connection point of the hollow block 10, so that the collecting bucket 11 at the end of the connecting frame 12 is opened and inserted into the sediment. Then, the electric push rod 20 is extended to pull the connecting frame 12, so that the collecting bucket 11 is closed to grab the sediment sample.

[0041] After the sediment sample is collected, the driving motor 17 is started to reverse to drive the connecting rod 19 to reverse rotation, so that the rope 18 and the rope 18 are retracted, and the hollow block 10 containing the sediment sample and the grab assembly are lifted to the water surface, and the collection of the sediment sample is completed.

[0042] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solution recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
