Description

Technical Field

[0001] The invention relates to the field of marine sludge sampling, and in particular to a seabed mud sampling robot used for marine ecological monitoring. Background Art

[0002] Marine ecology generally includes the relationship between marine organisms and between marine organisms and their marine environment. By monitoring marine ecology, we can understand the safety of marine ecology and the changes in water quality in the sea area. Seabed silt is part of marine sediments. By testing seabed silt, we can reflect information such as marine geology, ecosystem health, environmental pollution, and detect resources such as seabed oil. The sampling of seabed silt is usually carried out by a special sampling robot.

[0003] The seabed sampling robot is placed on the deck of the ship and dropped into the seawater through a towing rope until the seabed sampling robot sinks to the bottom and can contact the muddy material on the seabed, and then the sampling structure inside the sampling robot is driven to perform sampling operations, and the sampling robot is lifted up after the sampling is completed. The existing Chinese public document (CN117147209A) records a seabed sediment sampling robot for new energy development, which records that the two driving parts are started to rotate by a remote controller to control the downward movement speed of the shell and its parts; in another Chinese public document (CN118032418A), a seabed mud sampling robot and sampling method for marine ecological monitoring are recorded, which records that the up and down moving propeller can make the entire device move vertically by rotating. In the above two documents, the propeller and the driving component have the same working principle and the same working method. However, since there are often abandoned fishing nets or linear marine debris sinking to the bottom of the sea, the propellers and driving components in the public documents are directly exposed to the seawater during operation. This makes it easy for the propeller and the driving component to be entangled by the abandoned fishing nets or linear marine debris during high-speed rotation, ultimately affecting the normal sampling operation of the sampling robot.

[0031] It also includes: a protection unit, which is used to prevent linear marine garbage or seabed strip-shaped materials from being entangled between the spiral blade 6 and the first drive motor 7, and the protection unit is coated on the outside of the transverse frame 2;

[0032] The cutting unit is used to cut and separate linear marine garbage or seabed strip materials attached to the outside of the protection unit. The cutting unit is located inside the transverse frame 2.

[0033] The protection unit includes two symmetrically distributed semi-cylinders 3 fixedly arranged at both ends of the transverse frame 2. The outside of the transverse frame 2 and the semi-cylinders 3 are fixedly provided with skirts, and a receiving slot 8 is opened in the skirt. The number of the receiving slots 8 is two and they are relatively distributed. A first toothed belt 9 is slidably installed inside each receiving slot 8, and a metal mesh belt 4 is fixedly connected between the two first toothed belts 9. The metal mesh belt 4 is covered on the outside of the sampling robot shell 1 and the transverse frame 2. A driving component for driving the first toothed belt 9 is also provided inside the transverse frame 2. The metal mesh belt 4 is made of a flexible material, is annular, and can move with the two first toothed belts 9.

[0034] The driving component includes a hollow cavity opened in the middle section of the transverse frame 2, and a mounting plate 10 is fixedly mounted inside the hollow cavity, and a first rotating shaft 12 is also rotatably mounted inside the hollow cavity. Both ends of the first rotating shaft 12 are fixedly mounted with toothed discs 15, and the two toothed discs 15 are respectively engaged with the two first toothed belts 9 for transmission. The first rotating shaft 12 is located below the mounting plate 10, and a second driving motor 11 is fixedly mounted above the mounting plate 10. The output end of the second driving motor 11 rotates through the mounting plate 10, and a worm 13 is fixedly mounted on the output end of the second driving motor 11, and a worm wheel 14 engaged with the worm 13 is fixedly mounted on the outer surface of the first rotating shaft 12. Through the transmission of the worm wheel 14 by the worm 13, the second driving motor 11 can drive the toothed disc 15 to drive with the first toothed belt 9.

[0035] The middle positions of the upper and lower end surfaces of the transverse frame 2 are fixedly equipped with receiving plates 5, and the metal mesh belt 4 is located between the receiving plate 5 and the transverse frame 2, squeezing the first toothed belt 9 between the toothed disc 15 and the receiving plate 5, thereby ensuring the transmission stability of the first toothed belt 9.

[0036] The cutting unit includes two rotating wheels 16 vertically rotatably mounted inside the mounting plate 10, the rotating wheels 16 and the first rotating shaft 12 are vertically distributed, and an eccentrically distributed hollow cylinder 17 is fixedly inserted inside the rotating wheel 16, and slide rods 18 are slidably mounted on the upper and lower end surfaces of the hollow cylinder 17, and a cutting plate 20 is fixedly arranged at one end of each slide rod 18 away from the hollow cylinder 17, and a first spring 19 is fixedly arranged between each cutting plate 20 and the hollow cylinder 17, and a plurality of first springs 19 are correspondingly distributed on the outside of a plurality of slide rods 18, and a transmission component is also arranged between the two rotating wheels 16 and the second driving motor 11, and the cutting plate 20 can be tightly fitted with the inner wall of the metal mesh belt 4 through the action of the first spring 19.

[0037] The transmission component includes a transmission gear 21 fixedly mounted on the outer surface of the output end of the second drive motor 11. A plurality of teeth 22 equidistantly distributed around the circumference are fixedly arranged on the outside of each rotating wheel 16, and a second toothed belt 23 is installed between the two groups of teeth 22 and the transmission gear 21. The second drive motor 11 can also drive the two rotating wheels 16 to rotate inside the mounting plate 10 through the action of the teeth 22, the transmission gear 21 and the teeth 22.

[0038] Each cutting plate 20 is tightly attached to the inner wall of the metal mesh belt 4 under the elastic pressure of the first spring 19, and the cutting edge of the cutting plate 20 is made of diamond material. The diamond cutting edge can make the cutting edge of the cutting plate 20 sharper and can effectively cut the linear or strip materials stuck in the metal mesh belt 4.

[0039] The edge of each hole of the metal mesh belt 4 is chamfered to avoid burrs on the edges of the holes of the metal mesh belt 4 and to avoid frequent contact between the burrs and the cutting edge of the cutting plate 20, which would damage the cutting edge of the cutting plate 20.

[0040] Working principle: When the sampling robot performs sampling operations on the seabed and adjusts its position, the two first drive motors 7 drive the two spiral blades 6 to rotate at high speed. The high-speed rotation process can quickly transport the seawater below the horizontal frame 2 in a vertical shape. The seawater can increase the buoyancy of the sampling robot shell 1 during the high-speed flow of the seawater, thereby adjusting the position of the sampling robot. In the process of the high-speed rotation of the spiral blades 6 to increase the flow rate of part of the seawater, the metal mesh belt 4 can effectively prevent the discarded fishing lines or kelp, seaweed and other ribbon-like materials in the ocean from being entangled between the spiral blades 6 and the first drive motor 7, thereby ensuring that the sampling robot can be transferred to a normal position on the seabed;

[0041] In order to prevent discarded fishing lines or strip-shaped materials such as kelp and seaweed from adhering to the metal mesh belt 4 and affecting the efficiency of the spiral blade 6 in conveying part of the seawater, the second drive motor 11 can drive the first rotating shaft 12 and the toothed disc 15 to transmit through the action of the worm 13 and the worm wheel 14. Through the engagement of the toothed disc 15 with the first toothed belt 9, the metal mesh belt 4 can be rotated cyclically, thereby transferring the position of the discarded fishing lines or kelp and seaweed attached to the metal mesh belt 4. When the second drive motor 11 is started, the two rotating wheels 16 can also rotate eccentrically with the two hollow cylinders 17 through the action of the transmission gear 21, the teeth 22 and the second toothed belt 23. During the eccentric rotation, the cutting plate 20 will reciprocate at a high frequency against the metal mesh belt 4. When the discarded fishing lines or kelp and seaweed stuck in the metal mesh belt 4 come into contact with the blade of the cutting plate 20, they will be cut off, and the cut discarded fishing lines or kelp and seaweed will be discharged through the fluidity of the seawater.

[0042] It should be noted that in the present embodiment, the slide rod 18 slides axially in the hollow cylinder 17 .

[0043] Example 2: Please refer to Figure 8 and Fig. 9 This embodiment is a further explanation of the first embodiment. A cleaning unit for cleaning the holes of the metal mesh belt 4 is further provided inside the hollow cavity. The cleaning unit includes two brush plates 30 placed inside the hollow cavity. A plurality of bristles 36 are inserted into the end of each brush plate 30 away from the mounting plate 10. A hollow notch 24 is provided in the center of one of the receiving plates 5 close to the bristles 36. Two symmetrically distributed connecting rods 27 are fixedly mounted on the end of each brush plate 30 close to the mounting plate 10. A sliding disc 26 is fixedly sleeved on the end of the connecting rod 27 away from the brush plate 30. The outer surface sliding sleeve of the disk 26 is provided with a lifting cylinder 25, and the lifting cylinder 25 is fixedly lifted at the bottom of the mounting plate 10, and a third spring 28 is fixedly assembled between one group of sliding disks 26 on the same side which is away from the end of the mounting plate 10 and the lifting cylinder 25, and a second spring 29 is fixedly assembled between the other group of sliding disks 26 on the same side which is away from the end of the mounting plate 10 and the lifting cylinder 25, and a trigger component is arranged between the two brush plates 30, and the two brush plates 30 move up and down alternately to allow the bristles 36 to pass through the holes of the metal mesh belt 4 to remove the mud, sand and impurities attached to the holes.

[0044] The trigger component includes a second rotating shaft 35 located between the two mounting plates 10, and the second rotating shaft 35 is the symmetry center of the two brush plates 30, and the two ends of the second rotating shaft 35 are rotatably embedded in the interior of the cross frame 2, and the outer surface of the second rotating shaft 35 is also fixedly mounted with a pressing block 34 for alternately pressing the two brush plates 30, and the end of one of the pressing blocks 34 is fixedly inserted with a column 33 at one end close to the mounting plate 10, and a turntable 31 is fixedly provided at the end of the worm 13 away from the mounting plate 10, and an inclined arc plate 32 for pushing the column 33 is also fixedly provided on the other end face of the turntable 31. The inclined arc plate 32 is arc-shaped, and the end face is an inclined surface. When the inclined arc plate 32 rotates with the turntable 31, it can frequently push the column 33.

[0045] In this embodiment, the sampling robot shell 1 performs sampling on the seabed. During the later movement, it will stir up the mud and sand on the seabed. Such materials are small and easily blocked in the holes of the metal mesh belt 4. Figure 8 , 9 The state of the two brush plates 30 in the middle, the third spring 28 is in a compressed state, and the second spring 29 is in an uncompressed state, and the elastic stiffness of the third spring 28 is less than the elastic stiffness of the second spring 29. When the turntable 31 rotates with the inclined arc plate 32, the inclined arc plate 32 can frequently squeeze the column 33. During each squeezing process, the second spring 29 can be compressed. At the same time, when the third spring 28 is not blocked by the pressing block 34, it will lift up with another set of brush plates 30 at the bottom;

[0046] When the inclined arc plate 32 pushes the column 33 to the maximum distance and then separates from the column 33, the second spring 29 with greater elastic stiffness will lift the brush plate 30 at its bottom again and press the third spring 28 on the other side, thereby realizing the alternating lifting and lowering of the two brush plates 30. When each brush plate 30 descends to the bottom, the bristles 36 can pass through the holes of the metal mesh belt 4, thereby removing impurities in the holes and avoiding clogging of the holes. The bristles 36 are made of nylon and have strong toughness, which can push impurities in the holes.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
