Description

Technical Field

[0001] The present invention relates to the technical field of ocean waste dumping instruments, in particular to an ocean waste dumping instrument with a Beidou positioning function. Background Art

[0002] The ocean dumping instrument is a device that can collect, transmit and store a variety of data such as the dumping ship's track, draft, dumping time, video signal, mud gate opening status, etc. in real time, and conduct real-time dynamic visual monitoring of dumping activities. When working, it needs to be electrically connected to the pressure water level gauge, Beidou positioning terminal, video monitoring and communication module through connecting lines.

[0003] Existing marine waste dumping instruments often arrange multiple connectors on one side of the casing. The interfaces on the connecting lines are normally equipped with threaded connectors, which improve the stability of the connecting lines fixed to the main unit through threaded connection. However, there is a problem with this dense interface design during use. That is, when the user rotates one of the threaded connectors, it will be interfered with by the previously installed connecting lines and interfaces, which makes the operation inconvenient. Moreover, when rotating and tightening, the user's hands will inevitably come into contact with adjacent connecting lines and interfaces. The friction generated by the rotation may inadvertently cause the previously installed threaded connector interface to loosen. Secondly, the instrument is usually installed on the hull. The vibration frequency on the hull is higher than that on the ground. Long-term vibration can also easily cause the threaded connection interface to loosen. Regardless of the reason for the loose interface, it is difficult for the user to detect it with the naked eye. When a certain connecting line interface is out of contact, causing a certain function to fail or be intermittently effective, it is difficult for the user to detect.

[0004] Therefore, we propose an ocean dumping instrument with Beidou positioning function to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-11As shown, a marine waste dumping instrument with Beidou positioning function includes a marine waste dumping instrument body 1, at least two or more threaded connection ends 2 are provided on one side of the bottom of the marine waste dumping instrument body 1, and a threaded connector 3 for connecting wires is screwed on the outer side of the threaded connection end 2. A fixed frame 4 is provided on the side of the bottom of the marine waste dumping instrument body 1 near the threaded connection end 2, and a narrow frame is fixed on the top of the fixed frame 4. The narrow frame is used to position the threaded connection end 2, so as to facilitate fixing the fixed frame 4 to the outside of the marine waste dumping instrument body 1 and to reduce its occupied area to avoid interference between two adjacent narrow frames. At least two or more independent installation cavities 5 are provided in the fixed frame 4, and a single installation cavity 5 is arranged relative to the threaded connection end 2 up and down. The installation cavity 5 is used Installation-related structures are provided, and the same number of circular holes as the installation cavities 5 are provided on the front side of the fixed frame 4. The circular holes are used to allow the cover plate 29 to pass through. The bottom of the installation cavity 5 is rotatably connected to a connector positioning component 6 that allows the threaded connector 3 to slide inside. The front end of the installation cavity 5 is provided with a driving component 7 that can drive the connector positioning component 6 to rotate. Through the provided connector positioning component 6 and driving component 7, the threaded connector 3 of each interface can be arranged independently. The user pulls the rotating part 22 from the push-pull groove 12 on the outside to rotate, thereby realizing the connection and disassembly of the internal threaded connector 3 and the threaded connection end 2 on the ocean dumping instrument body 1, avoiding contact friction on the adjacent threaded connector 3 interfaces caused by direct operation by the user.

[0036] In this embodiment, the drive assembly 7 includes a connecting component 8 near one side of the connector positioning component 6, a deceleration component 9 is provided in front of the connecting component 8, a limiting component 10 is provided in front of the deceleration component 9, and a locking component 11 is provided in front of the limiting component 10. The connecting component 8 is used to cooperate with the connector positioning component 6 to facilitate changing the transmission direction, so that the user can rotate the rotating portion 22 on the front side to realize the horizontal rotation of the threaded connector 3, which reduces the difficulty of observing the rotation changes of the threaded connector 3. The deceleration component 9 adopts the form of a planetary gear system for transmission cooperation, which can reduce the transmission space. If a gear rack is adopted, the rotation at the front end of the fixed frame 4 can also be achieved to drive the rotation of the vertical threaded connector 3. However, this method has too high requirements on the length of the rack. In order to make the threaded connector 3 rotate multiple times, the required rack length is long, which may cause one end of the rack to pass through and extend to the outside of the fixed frame 4. At the same time, the deceleration component 9 takes up less space. Another advantage is that a set of deceleration components 9 and drive assembly 7 can be independently provided in each installation cavity 5, which can reduce the number of differentiated structures and reduce the difficulty and cost of processing and manufacturing.

[0037] In this embodiment, the connector positioning assembly 6 includes a support ring 13 rotatably connected to the inner wall of the bottom of the installation cavity 5, and a first bevel gear 14 is fixed in the support ring 13, and a sliding sleeve 15 with a tooth groove is fixed in the first bevel gear 14. The sliding sleeve 15 is slidably connected to one of the threaded connectors 3, and the inner periphery of the sliding sleeve 15 is densely covered with tooth grooves. The same tooth ring is also provided on the outer side of the threaded connector 3. The tooth ring and the tooth groove are fitted with a minimum degree of interference so that the threaded connector 3 can be subjected to a certain degree of resistance when inserted, so that the threaded connector 3 can be fully inserted and limited in the sliding sleeve 15. The threaded connector 3 can be driven to rotate by the sliding sleeve 15, and the threaded connector 3 is rotatably connected to the outer side of the internal wire thereof. When the threaded connector 3 is threadedly connected with the threaded connection end 2, it will rotate and rise, driving the internal wire to rise straightly and be inserted into the interface in the threaded connection end 2. By providing the connector positioning assembly 6, the inserted threaded connector 3 can be pre-limited and positioned.

[0038] In this embodiment, the connecting component 8 includes an outer sealing sleeve 16 fixedly arranged on the front side of the installation cavity 5. The outer sealing sleeve 16 is used to install the components of various parts. A second bevel gear 17 is rotatably connected between the inner wall of the rear side of the outer sealing sleeve 16. The second bevel gear 17 and the first bevel gear 14 are engaged with each other. A central shaft 18 is fixed in the second bevel gear 17. The central shaft 18 passes through the rear chamber of the outer sealing sleeve 16 and extends to the front thereof. Through the mutual engagement between the second bevel gear 17 and the first bevel gear 14, the transmission and driving direction can be changed to the front direction facing the ocean dumping instrument body 1, so that the user can observe the instrument from the front.

[0039] In this embodiment, the deceleration component 9 includes a gear ring 19 rotatably connected to the inner wall of the rear side of the outer sealing sleeve 16, and a gear portion 20 is fixed to the front side of the second bevel gear 17. The gear portion 20 rotates synchronously with the second bevel gear 17, and its angular velocity remains consistent. The inner wall of the rear side of the outer sealing sleeve 16 and is located between the gear ring 19 and the gear portion 20. A meshing gear 21 is also rotatably connected. The meshing gear 21 is simultaneously engaged with the gear portion 20 and the adjacent gear ring 19. The meshing gear 21 is used to drive the gear portion 20 and the second bevel gear 17 when the gear ring 19 rotates. The second bevel gear 17 rotates synchronously, and the rotation angle of the second bevel gear 17 can be increased, so that the rotation angle of the ring gear 19 is much larger than the rotation angle of the second bevel gear 17. This part of the structure can also be implemented in any way, so that the rotation angle of the rotating portion 22 can be less than 0.1 times the rotation angle of the sliding sleeve 15 and the threaded connector 3. A rotating portion 22 is fixed on one side of the front end surface of the ring gear 19. The rotating portion 22 is used to extend to the outside of the cover plate 29, which is convenient for the user to manipulate the rotating portion 22 from the outside to drive the ring gear 19 to rotate, and it is also convenient for the user to judge the screw through the rotating portion 22. Whether there is looseness between the threaded connector 3 and the threaded connection end 2, an arc groove 24 is provided on the front side of the outer sealing sleeve 16, and the arc groove 24 can facilitate the passage of the rotating part 22 to avoid interference between the rotating part 22 and the outer sealing sleeve 16. A push-pull groove 12 for gripping is provided on the rotating part 22. The push-pull groove 12 is used to provide a force point for the user when operating the rotating part 22, which is convenient for operation and use. The transmission ratio between the rotating part 22 driven by the user and the sliding sleeve 15 required to control the rotation can be adjusted by setting the deceleration component 9, so as to facilitate the rotation of the rotating part 22. It can be used as a driving structure as well as an observation structure. Through the coordination of the rotating part 22, the arc groove 24, the inspection groove 30 and the pointer groove 31, the user can judge whether the interface of the threaded connector 3 at that location is loose by observing the relative position of the external pointer groove 31 and the rotating part 22, so that the loose problem of the interface can be visually observed. Through the deceleration component 9, the large angle required for the rotating sleeve 15 can be reduced to adapt to the small angle of rotation of the rotating part 22, which makes it more convenient for the user to observe the changes.

[0040] In this embodiment, a sealing ring 23 is fixedly provided on the outer side of the rotating part 22, and the sealing ring 23 is rotatably connected to the front side of the outer sealing sleeve 16. The sealing ring 23 is used to seal and shield the arc groove 24 opened on the outer sealing sleeve 16 from the outside, thereby protecting the internal structure and avoiding internal contamination.

[0041] In this embodiment, the limiting component 10 includes a ratchet 25 fixed on the outer front side of the central shaft 18, and the ratchet 25 rotates synchronously with the central shaft 18. A central groove 26 is opened in the middle of the front end of the outer sealing sleeve 16. The central groove 26 is used to accommodate and hide the structure in the limiting component 10 to prevent it from protruding from the front end surface of the outer sealing sleeve 16. A pawl 27 is rotatably connected in the central groove 26. A leaf spring 28 is fixed on the inner wall of the central groove 26 near the pawl 27. The leaf spring 28 is used to abut the pawl 27 so that it always abuts against the outside of the ratchet 25 without any other interference. One side of the leaf spring 28 abuts against the outer wall of the adjacent pawl 27. Through the setting of the limiting component 10, the central shaft 18 can be rotated only in a single direction under normal circumstances, thereby preventing the internal threaded connector 3 from loosening and reversing under long-term vibration.

[0042] In this embodiment, a cover plate 29 is fixed to the front end of the outer sealing sleeve 16, and an inspection groove 30 for the rotating part 22 to pass through is opened on the cover plate 29. A pointer groove 31 is opened at the front end of the cover plate 29, and the cover plate 29 is used to close the front side of the outer sealing sleeve 16. The inspection groove 30 is used to indicate the minimum angle change required for the rotating part 22 to rotate after the threaded connector 3 is tightly connected with the threaded connection end 2. If it is lower than this angle, it means that there is looseness between the threaded connector 3 and the threaded connection end 2. The actual opening position of the inspection groove 30 is determined by the actual transmission ratio between the ring gear 19 and the first bevel gear 14. At the same time, the minimum rotation angle between the threaded connection end 2 and the threaded connector 3 and the relationship between the above-mentioned transmission ratios are determined to calculate the actual opening inclination angle of the inspection groove 30. The inspection groove 30 can facilitate the rotating part 22 to pass through the cover plate 29 and rotate flexibly therein.

[0043] In this embodiment, the locking component 11 includes a locking shaft 32 fixed to the front side of the pawl 27, and the locking shaft 32 is used to control the position of the pawl 27 from the outside. A movable groove 33 for the locking shaft 32 to pass through is provided on one side of the front side of the cover plate 29. The movable groove 33 is used to allow the locking shaft 32 to move flexibly in the movable groove 33 as the pawl 27 rotates. A slide portion 34 is fixed above the movable groove 33 and located on the cover plate 29. The slide portion 34 is used to limit and guide the locking member 36. After the locking member 36 is installed, a fixing hole is provided on the slide portion 34. By driving a pin into the hole, the maximum height of the slide portion 34 can be limited, thereby limiting the locking member 36 outside the slide portion 34. It cannot detach naturally, and slide grooves 35 are provided on the left and right sides of the front side of the slide part 34. A locking member 36 for limiting the lock shaft 32 is provided on the front side of the slide part 34. The locking member 36 can limit the lock shaft 32 under normal circumstances to prevent it from rotating naturally, thereby further improving reliability. The provided locking component 11 can facilitate the user to pull the pawl 27 from the outside to separate it from the ratchet 25, so that the center shaft 18 can move in the opposite direction with the rotation of the ring gear 19, which is used to release the connection between the threaded connector 3 and the threaded connection end 2. At the same time, it can also prevent the lock shaft 32 from driving the pawl 27 and the ratchet 25 to deviate in the event of accidental contact, causing the pawl 27 to lose its control over the ratchet 25.

[0044] The locking member 36 is fixed with a plurality of sliders 38 on the left and right sides of the locking member 36 so that the locking member 36 can slide within the outer limit of the slide portion 34 by means of the slide 35. The slider 38 is slidably connected to the inner side of the slide portion 34. The locking member 36 is provided with a strip pressure groove 39 on the lower end thereof. The strip pressure groove 39 is used to move downward and press on the outer side of the lock shaft 32, so that the rotational movement of the lock shaft 32 is difficult to drive the vertical movement of the locking member 36, thereby realizing the position restriction of the lock shaft 32 by the locking member 36. The locking member 36 is provided with pressing grooves 40 on the left and right sides of the locking member 36. The pressing grooves 40 can increase the friction between the locking member 36 and the user's hand on both sides, making it easier to bear force and reducing the difficulty of operation. By cooperating with the limiting component 10 and the locking component 11, the natural loosening of the threaded connector 3 can be avoided after the connecting line is installed, thereby avoiding the influence of the long-term vibration of the hull on the connection of the threaded connector 3, thereby ensuring the stability of the interface connection on the instrument.

[0045] When the present invention is used in practice, when the user uses the ocean dumping instrument, he first fixes the ocean dumping instrument body 1 on the wall through the hanging ring, drives the fasteners into the wall through the hanging ring, and after fixing the ocean dumping instrument body 1, connects it to the power cord, and then checks whether one end of the rotating part 22 on the front end surface of the fixed frame 4 is located at the leftmost end of the inspection groove 30. If so, proceed to the next step. If not, the nearest locking part 36 should be pulled upward so that the upper strip pressure groove 39 is no longer pressed on the outside of the lock shaft 32, and then the lock shaft 32 is pushed to move in the movable groove 33, so that it drives the pawl 27 away from the ratchet 25 and pushes the adjacent leaf spring 28 to increase the internal elastic force of the leaf spring 28, and then the rotating part 22 is held and rotated counterclockwise until Until it abuts against the leftmost end of the inspection groove 30, then release the lock shaft 32, so that the pawl 27 is reset under the elastic force of the leaf spring 28 and abuts against the outside of the ratchet 25 again, and at the same time push the locking piece 36 downward so that the strip pressure groove 39 on it is pressed against the outside of the slider 38 again, then take the end of the connecting line with the external device with the threaded connector 3 in your hand, align it with the bottom of one of the installation cavities 5, and send the end of the connecting line with the threaded connector 3 into the installation cavity 5 so that it is inserted into the corresponding sliding sleeve 15. It should be noted that when inserting, the threaded connector 3 should be aligned with the inner tooth groove of the sliding sleeve 15 before it can be inserted. After insertion, keep pushing the threaded connector 3 upward. After pushing once, move your hand downward for a while. The hand continues to push upward until it can no longer be pushed. At this time, the hand continues to maintain the upward pressure state and rotates the rotating part 22 of the front end face of the fixed frame 4 with force to drive the ring gear 19 to rotate. When the ring gear 19 rotates, it drives the gear part 20 to rotate through the meshing gear 21. When the gear part 20 rotates, it drives the central shaft 18 and the second bevel gear 17 to rotate at high speed. When the second bevel gear 17 rotates, it drives it and the sliding sleeve 15 to rotate by meshing with the first bevel gear 14. When the sliding sleeve 15 rotates, it drives the threaded connector 3 inserted therein to rotate. At the same time, the threaded connector 3 is squeezed upward by the hand so that its upper end face contacts the inner surface of the threaded connection end. At the same time, it is threadedly connected with the threaded connection end under the action of the rotational force of the sliding sleeve 15, so that the threaded connector 3 drives the internal connecting wire upward in the sliding sleeve 15 until the end face of the connecting wire is completely inserted into the connecting port in the threaded connecting end 2. At this time, the rotating part 22 is difficult to continue to rotate clockwise. At this time, check whether the limiting component 10 is working properly. Specifically, rotate the rotating part 22 counterclockwise to drive the ring gear 19 to rotate in the opposite direction. Through the meshing gear 21, the central shaft 18 is driven to rotate in the opposite direction. When the central shaft 18 rotates in the opposite direction, it drives the ratchet 25 at the front end to reverse. At this time, the pawl 27 is restricted by the structure of the ratchet 27 and is stuck on the outside of the ratchet 25. The ratchet 25 cannot rotate, which makes the central shaft 18, the ring gear 19 and the rotating part 22 unable to reverse. At this time, it proves that the limiting component 10 is working properly. Then the user can connect the next connecting wire.Until all external devices that need to be connected to the ocean dump instrument body 1 are connected, during daily use of the ocean dump instrument body 1, the user can judge whether the internal structure is working properly by observing the status of the rotating part 22 and the locking shaft 32. If the rotating part 22 is located to the right of the inspection groove 30, it proves that the internal interface is still tightly connected. If the locking shaft 32 is still stuck in the strip-shaped pressing groove 39 and is at the lowest point, it proves that the limiting component 10 is still working properly.
