Description

Technical Field

[0001] The invention relates to the technical field of water area sampling and detection, and in particular to a water area bottom undisturbed sediment sampling device. Background Art

[0002] The sampling of undisturbed sediments in water areas is also called sediment sampling. Pollutants in sediments not only affect the water environment, but may also cause harm to aquatic life. Through sampling and testing of undisturbed sediments in water areas, pollutants that may threaten aquatic life can be discovered and dealt with in a timely manner, thereby maintaining the balance of the aquatic ecosystem. In some plateau areas, the sampling of undisturbed sediments in water areas uses an artificial pulling rope, with a sampler bound to one end of the rope. Due to the lack of oxygen in the plateau area, the manual pulling of the sampler is extremely difficult, and it requires the cooperation of multiple people and the exchange of pulling to barely complete the sampling work. Therefore, it is necessary to design a sampling device for undisturbed sediments in water areas to replace the manual pulling sampler. Therefore, we propose a sampling device for undisturbed sediments in water areas. Summary of the invention

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Embodiment 1, as Figure 1-3 As shown, the present invention provides a technical solution: a sampling device for undisturbed sediments in a water area, comprising a hull mechanism, a lifting and hoisting mechanism arranged at the bow position of the hull mechanism, the hull mechanism comprising a hull 1 and a power mechanism 2, the lifting and hoisting mechanism comprising a base 4, a V-frame 5, a U-shaped seat 1 6, a guide wheel 7, a lifting rope 8, a U-shaped seat 2 9, a winch wheel 10, and a motor 11, one end of the lifting rope 8 is overlapped in the guide groove of the guide wheel 7, and the other end is fixedly connected to the surface of the winch wheel 10, the motor shaft of the motor 11 is dynamically connected to the winch wheel 10 through a sliding connection structure, the sliding connection structure comprises a shaft body 17 coaxially connected to the motor shaft of the motor 11, a shaft sleeve 16 slidably sleeved on the outside of the shaft body 17, a chuck 15 is fixedly arranged at one end of the shaft sleeve 16, a slot disk 14 clamped with the chuck 15 is coaxially arranged at one end of the winch wheel 10, and a manual turntable 12 is coaxially arranged at the other end of the winch wheel 10.

[0017] In a specific embodiment of the present invention, the motor 11 is controlled by an independent controller, and the electric energy of the motor 11 is provided by the battery carried by the hull 1. The controller can control the forward and reverse rotation of the motor 11. The end of the lifting rope 8 is connected to the sampler. In the initial state, the sampler needs to be lifted to a position close to the guide wheel 7, and then the power mechanism 2 drives the hull 1 to reach the designated sampling position in the water area, and controls one end of the lifting rope 8 to slowly descend, and then the sampler gradually descends below the water surface, thereby taking the original sediment on the bottom of the water. After the sampling is completed, the motor 11 drives the winch wheel 10 to rotate and recover the lifting rope 8, thereby lifting the sampler, and the power mechanism 2 drives the hull 1 to the waterside, removes the sampler, and completes the sampling of original sediments on the bottom of the water area in the plateau area. There is no need for personnel to lift the sampler, and the V-frame 5 and the base 4 form a triangular stable structure, making the entire lifting structure more stable.

[0018] In the preferred technical solution, a convex key is fixedly provided on the surface of the shaft body 17, and a groove for inlaying and cooperating with the convex key is provided on the inner wall surface of the sleeve 16. The convex key of the shaft body 17 always cooperates with the groove on the inner wall surface of the sleeve 16, so that the shaft body 17 can still drive the sleeve 16 to rotate after the sleeve 16 slides into position.

[0019] In the preferred technical solution, a plurality of magnetic blocks are fixed around the surface of the chuck 15 on one side facing the slot disk 14. A slot for inlaying and cooperating with the magnetic block is opened on the surface of the slot disk 14 on the one side facing the chuck 15. The magnetic block is snapped into the slot. Not only can the magnetic block be magnetically adsorbed and connected to the slot, but the magnetic block is snapped into the slot to provide torque, so that the chuck 15 can drive the slot disk 14 to rotate.

[0020] In the preferred technical solution, the bottom of the U-shaped seat 6 is welded and fixed to the top of the V-shaped frame 5, the bottom end of the V-shaped frame 5 is welded and fixed to the top of the base 4, a partition 3 is installed in the cabin of the hull 1 by gluing, and the base 4 is fixed to the top of the partition 3 by bolts, and the partition 3 is used to provide an installation platform for the lifting and hoisting mechanism.

[0021] In the preferred technical solution, the winch wheel 10 is rotatably installed on the inner side of the U-shaped seat 29 through the central axis 13, one end of the central axis 13 passes through one side of the U-shaped seat 29 and one end of the central axis 13 is fixedly connected to the manual turntable 12 by bolts. The manual turntable 12 can manually drive the winch wheel 10 to rotate to retract and release the lifting rope 8 when the motor 11 fails. The U-shaped seat 29 is arranged at the stern of the hull 1, and a support frame is arranged under the U-shaped seat 29. The support frame is installed on the surface of the hull 1 by adhesive fixation. The bottom end of the V-shaped frame 5 is arranged on the hull of the hull 1, and the guide wheel 7 is located above the bow of the hull 1, which can improve the stability of the front and rear counterweights of the hull when lifting samples.

[0022] In the preferred technical solution, the power mechanism 2 includes a gasoline outboard motor, a drive controller and a propeller mechanism. The power mechanism 2 is arranged at the stern of the hull 1. The power mechanism 2 provides power for the hull 1 to move on the water. The output shaft of the gasoline outboard motor cooperates with the propeller through a reducer, and the propeller rotates to drive the hull 1 to move.

[0023] In the preferred technical solution, the horizontal distance between the guide wheel 7 and the bow of the hull 1 is 0.5m, and the vertical distance between the guide wheel 7 and the bottom of the hull 1 is 1.5m. Such dimensions are designed to reserve space for the sampler to avoid scratches between the sampler and the hull 1.

[0024] Working principle: The sampler is connected to the sampler through the end of the lifting rope 8, and the controller controls the motor 11 to lift the sampler to a position close to the guide wheel 7. The motor 11 drives the winch wheel 10 to rotate forward, thereby recovering the lifting rope, until the sampler is lifted to a position close to the guide wheel 7, and the power mechanism 2 drives the hull 1 to reach the designated sampling position in the water area, and the motor 11 drives the winch wheel 10 to rotate in the opposite direction, and one end of the lifting rope 8 slowly descends, and the sampler gradually descends below the water surface, thereby taking the original sediment on the bottom of the water. After the sampling is completed, the motor 11 drives the winch wheel 10 to rotate and recover the lifting rope 8, thereby lifting the sampler, and the power mechanism 2 drives the hull 1 to reach the waterside and remove the sampler. When the motor 11 drives the winch wheel 10 to rotate, the chuck 15 is tightly installed with the card slot disk 14, and the magnetic block is connected to the card slot. When the motor 11 fails, the sliding sleeve 16 separates the chuck 15 from the card slot disk 14, and the manual turntable 12 is used to drive the winch wheel 10 to rotate, thereby ensuring that the sampler can be taken and placed normally.
