Description

Technical Field

[0001] The present invention belongs to the technical field of cage aquaculture, and particularly relates to a lifting mechanism for a positioning pile of a culture cage. Background Art

[0002] Cage aquaculture is a technology that confines aquatic organisms (such as fish, shellfish, and shrimp) in a box made of netting and conducts intensive aquaculture using natural waters (lakes, rivers, oceans). When conducting cage aquaculture, a lifting mechanism is required to pull the cage out of the aquaculture water for subsequent operations.

[0003] The existing lifting mechanism consists of a motor, gears, and racks arranged outside the pillars. There are four pillars, and the lifting mechanism is connected to the four corners of the cage and sleeved outside the corresponding pillars. The cage is driven to rise and fall along the pillars by the lifting mechanism. However, when the existing lifting mechanism is in use, the teeth on the rack above the pillar are relatively far from the ground, and it is not possible to ensure inspection and maintenance before each use. Therefore, when the teeth are deformed or there is a hard lump formed by excessive accumulation of impurities and particulate matter on their surfaces, these conditions cannot be detected in a timely manner. These problems will cause the lifting mechanism to get stuck at the problematic teeth during use, resulting in abnormal use. At this time, the lifting mechanism and the cage need to be reset, and then the problematic teeth need to be processed, which greatly delays the work progress. Summary of the Invention

[0004] In view of the above problems, the present invention provides a lifting mechanism for a positioning pile of a culture cage to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a lifting mechanism for an aquaculture cage positioning pile, as shown in Figures 1 to 7As shown in the figure, it includes a connecting plate 1 and a support column 2. The connecting plate 1 is slidably sleeved outside the support column 2. There are four connecting plates 1, which are respectively fixedly connected to the four corners of the top of the net cage. An elevating assembly for driving it to climb along the support column 2 is provided outside the connecting plate 1. The elevating assembly includes: a first tooth 3, a second tooth 4, a third tooth 5, a switching assembly, a protection assembly, and a power assembly provided on the outside of the support column 2; A plurality of first teeth 3 are symmetrically and fixedly installed on both sides of the support column 2. A plurality of second teeth 4 are provided and located directly above the first teeth 3. The number of second teeth 4 is multiple times that of the first teeth 3. The second teeth 4 are divided into multiple groups, each group containing a plurality of second teeth 4. The multiple groups of second teeth 4 are arranged from top to bottom above the first teeth 3. The switching assembly is used to drive the second teeth 4 and the third teeth 5 to change positions. The protection assembly is used to protect the third teeth 5. Through the protection assembly, it can prevent the third teeth 5 from being attached by external impurities, avoiding the formation of hard lumps due to long-term accumulation and affecting the use. The power assembly provides power for the cooperation of the connecting plate 1 with the first teeth 3, the second teeth 4, and the third teeth 5. The second teeth 4 and the third teeth 5 are arranged adjacent to each other left and right. The number of the third teeth 5 is the same as that of the second teeth 4. The shapes and sizes of the first teeth 3, the second teeth 4, and the third teeth 5 are the same. The third teeth 5 are also grouped, and the number of a group of third teeth 5 is the same as that of a group of second teeth 4.

[0028] During use, the connecting plate 1 is driven by the power assembly to move along the surfaces of the first teeth 3 and the second teeth 4, thereby driving the net cage to rise. During daily maintenance, since the first teeth 3 located below are at a low position, it is convenient to perform maintenance. However, the second teeth 4 are arranged at a position higher than the first teeth 3. Therefore, the maintenance of the second teeth 4 cannot be guaranteed to be in place. Therefore, during the rising process of the net cage, if the second teeth 4 are deformed or damaged by themselves, or there are hard lumps formed by excessive accumulation of impurity particles on their surfaces, these problems will all hinder the movement of the power assembly along the second teeth 4, resulting in the connecting plate 1 and the net cage being unable to rise smoothly;

[0029] Therefore, when the above situation occurs, if a group of second teeth 4 adjacent to the first teeth 3 has problems, the connecting plate 1 is driven by the power assembly to descend to the initial position, and a group of second teeth 4 and the third teeth 5 at the problem position are driven by the switching assembly to change positions. Due to the protection of the protection assembly, the third teeth 5 are in a normal state. By changing the position of the third teeth 5, the third teeth 5 are located above the first teeth 3 and aligned with the first teeth 3. Then, the connecting plate 1 is continuously driven to rise, and the power assembly moves along the surface of the normal third teeth 5, so that the connecting plate 1 can move normally;

[0030] If there is a problem with the second tooth 4 of other groups that are not adjacent to the first tooth 3, at this time, the position of the power assembly is retracted to the group of the second tooth 4 that is not problematic below, and then the problematic second tooth 4 is replaced according to the above principle. Subsequently, the normal movement of the power assembly can be ensured, and then the connecting plate 1 and the net cage can be lifted;

[0031] During the entire use process, when the second tooth 4 has a problem and causes the power assembly to malfunction, the positions of the group where the problematic second tooth 4 is located and the group where the third tooth 5 is located can be replaced, so that the normal third tooth 5 can be located above the power assembly, thereby ensuring the subsequent normal movement of the power assembly and ensuring the normal lifting of the net cage. Therefore, the situation where the entire process cannot proceed smoothly due to problems with the teeth located at a high position will not occur, ensuring the normal progress of the work.

[0032] In order to drive the second tooth 4 and the third tooth 5 to change positions, a switching component is provided, as Figure 3 shown. The switching component includes: an arc plate 6, an annular groove, and a magnetic drive component; the arc plate 6 is used to install the second tooth 4 and the third tooth 5, the annular groove is opened on the outside of the support column 2 for the arc plate 6 to slide, the arc plate 6 is provided in multiple numbers, and the multiple arc plates 6 are arranged from top to bottom along the annular groove. The second tooth 4 and the third tooth 5 are fixedly installed on the surface of the arc plate 6, and the magnetic drive component is used to drive the arc plate 6 to slide along the annular groove.

[0033] The magnetic drive component drives the arc plate 6 to slide along the annular groove, thereby driving the second tooth 4 and the third tooth 5 to change positions.

[0034] As Figure 3 shown, the magnetic drive component includes: a first groove and a second groove opened on the surface of the annular groove, a slider 7, an iron rod 8, a first elastic member 9, and an electromagnet 10; the slider 7 is used to connect the arc plate 6 and can slide along the first groove. The slider 7 is fixedly installed on the inner side of the arc plate 6. The iron rod 8 is used to connect the slider 7. The iron rod 8 is arc-shaped. One end of the iron rod 8 is fixedly connected to the slider 7, and the other end of the iron rod 8 extends into the second groove. The first elastic member 9 is a spring, sleeved on the outside of the iron rod 8 to drive the slider 7 to reset. The electromagnet 10 is arranged in the second groove, and the electromagnet 10 is fixedly installed on the inner wall of the second groove away from the iron rod 8. After the electromagnet 10 is energized, it can attract the iron rod 8 to move along the first groove and the second groove. The outside of the arc plate 6 is flush with the outside of the support column 2.

[0035] Energize the electromagnet 10 to make it magnetic, attracting the iron rod 8 to drive the slider 7 and the arc-shaped plate 6 to slide along the annular groove. The slider 7 compresses the first elastic member 9 to deform it. Eventually, one end of the iron rod 8 is adsorbed and fixed to the electromagnet 10. Cut off the power supply of the electromagnet 10 to make it lose magnetism. At this time, the first elastic member 9 resumes to drive the slider 7 to reset, thereby realizing the reset of the arc-shaped plate 6.

[0036] In order to protect the third tooth 5, a protection component is provided, such as Figure 3 shown. The protection component includes: a fixing plate 11, a pressing block 12, a second elastic member 13, and a protective cover 14. The fixing plate 11 is fixedly installed on the inner wall of the annular groove. The pressing block 12 is slidably arranged inside the fixing plate 11. A chute is formed on one side of the fixing plate 11 close to the electromagnet 10. The pressing block 12 is slidably arranged in the chute. The second elastic member 13 is a spring. The second elastic member 13 is arranged in the chute. One end of the second elastic member 13 is fixedly connected to the side of the pressing block 12 away from the support column 2, and the other side is fixedly connected to the inner wall of the chute. One end of the protective cover 14 is fixedly connected to the pressing block 12. An arc surface 15 is provided on the side of the protective cover 14 close to the second tooth 4. When the protective cover 14 covers the surface of the third tooth 5, there is a gap between the pressing block 12 and the inner wall of the chute close to the support column 2 at this time.

[0037] When the arc-shaped plate 6 drives the third tooth 5 to move, the third tooth 5 abuts against the protective cover 14 to drive the pressing block 12 to move along the chute. The pressing block 12 compresses the second elastic member 13. When the third tooth 5 leaves the protective cover 14, the second elastic member 13 drives the pressing block 12 and the protective cover 14 to move in the direction close to the support column 2. When the arc-shaped plate 6 drives the third tooth 5 to reset, after the third tooth 5 abuts against the arc surface 15, it cooperates with the arc surface 15 to squeeze the protective cover 14, causing the protective cover 14 to drive the pressing block 12 to move in the direction away from the support column 2. The pressing block 12 compresses the second elastic member 13. Eventually, the third tooth 5 resets and fits against the surface of the protective cover 14. The protective cover 14 can protect the third tooth 5.

[0038] In order to provide power for the cooperation of the connecting plate 1 with the first tooth 3, the second tooth 4, and the third tooth 5, a power component is provided, such as Figures 4 to 5 shown. The power component includes: a driving member 23, a gear 24, and a mounting bracket 25. The mounting bracket 25 is used to connect the connecting plate 1. The mounting bracket 25 is fixedly installed on the top of the connecting plate 1. The driving member 23 is a motor. Two driving members 23 are symmetrically and fixedly connected to the surface of the mounting bracket 25. The gear 24 is fixedly sleeved outside the driving shaft of the driving member 23. The gear 24 cooperates with the first tooth 3, the second tooth 4, and the third tooth 5.

[0039] Start the driving member 23 so that its drive shaft drives the gear 24 to rotate. The gears 24 on both sides rotate in opposite directions, and the gear 24 moves along the surfaces of the first tooth 3 and the second tooth 4, thereby driving the driving member 23, the mounting bracket 25, and the connecting plate 1 to move along the surface of the support column 2.

[0040] In order to be able to mark the second tooth 4 of the problem for faster subsequent maintenance, as Figures 4 to 5 shown, a marking component for marking the stuck part of the second tooth 4 is provided outside the mounting bracket 25. The marking component includes: an annular pipe 17 sleeved outside the drive shaft of the driving member 23. One end of the drive shaft of the driving member 23 is rotatably connected to the inner wall of the mounting bracket 25. The annular pipe 17 is sleeved outside the drive shaft and does not contact the drive shaft. A spray pipe 18, the position of the spray pipe 18 is in the same plane as the central axis of the gear 24 and is communicated with the annular pipe 17. The marking liquid sprayed from the spray pipe 18 can be sprayed onto the surface of the arc-shaped plate 6. A pump body 19 is arranged outside the mounting bracket 25. The pump body 19 is fixedly connected to the mounting bracket 25. The discharge end of the pump body 19 is communicated with the annular pipe 17. A box body 20 is filled with ink inside. The box body 20 is fixedly installed outside the mounting bracket 25. The extraction end of the pump body 19 is communicated with the box body 20. A control component is used to control the pump body 19 to work when the drive shaft of the driving member 23 is stuck.

[0041] When the gear 24 moves to the problematic second tooth 4, the gear 24 cannot continue to move along the second tooth 4, causing the drive shaft to fail to rotate normally. At this time, the control component controls the pump body 19 to work, extracts the ink in the box body 20, injects it into the annular pipe 17, and then sprays it onto the surface of the arc-shaped plate 6 through the spray pipe 18. The horizontal extension position of the ink on the surface of the arc-shaped plate 6 is the position of the problematic second tooth 4.

[0042] As Figure 5 shown, the control component includes: a sensor 21. The sensor 21 is a Hall sensor. The sensor 21 is fixedly connected to the outside of the driving member 23 and is used to detect the change of the current inside the driving member 23. A controller 22 is fixedly installed outside the box body 20 and is used to cooperate with the sensor 21 to control the start of the pump body 19.

[0043] After the drive shaft of the driving member 23 is stuck, the driving member 23 cannot operate normally at this time, and the current inside it increases instantaneously. At this time, the sensor 21 monitors the change of the current, and thus cooperates with the controller 22 to control the pump body 19 to start for a period of time and then stop.

[0044] As Figure 1 and Figure 7 shown, an opening 16 is provided on the connecting plate 1 for the first tooth 3, the second tooth 4, the third tooth 5 and the protection component to pass through.

[0045] Working principle: When in use, start the driving part 23 so that its driving shaft drives the gear 24 to rotate. The gears 24 on both sides rotate in opposite directions. The gear 24 moves along the surfaces of the first tooth 3 and the second tooth 4, thereby driving the driving part 23, the mounting frame 25, and the connecting plate 1 to move along the surface of the support column 2, and then driving the net cage to rise. During daily maintenance, since the first tooth 3 located below is at a low position, it is convenient for maintenance. However, the second tooth 4 is arranged at a position higher than the first tooth 3. Therefore, the maintenance of the second tooth 4 cannot be guaranteed to be in place. Therefore, during the rising process of the net cage, if the second tooth 4 itself is deformed and damaged, or there is a hard block formed by the accumulation of excessive impurity particles on its surface, these problems will hinder the movement of the gear 24 along the second tooth 4, resulting in the connecting plate 1 and the net cage being unable to rise smoothly;

[0046] Therefore, when the above situation occurs, if a group of second teeth 4 adjacent to the first tooth 3 has problems, drive the connecting plate 1 to descend to the initial position according to the above principle. Energize the electromagnet 10 to make it magnetic, attracting the iron rod 8 to drive the slider 7 and the arc plate 6 to slide along the annular groove. The slider 7 compresses the first elastic member 9 to deform it. Finally, one end of the iron rod 8 is adsorbed and fixed to the electromagnet 10. The arc plate 6 drives the second tooth 4 and the third tooth 5 to change positions, realizing the position change of a group of second teeth 4 and the third tooth 5 where the problem occurs. Through the protection of the protective cover 14, the third tooth 5 is in a normal state. When the arc plate 6 drives the third tooth 5 to move, the third tooth 5 abuts against the protective cover 14 to drive the pressing block 12 to move along the chute. The pressing block 12 compresses the second elastic member 13. When the third tooth 5 leaves the protective cover 14, at this time, the second elastic member 13 drives the pressing block 12 and the protective cover 14 to move towards the support column 2. By changing the position of the third tooth 5, the third tooth 5 is located above the first tooth 3 and aligned with the first tooth 3. Then continue to drive the connecting plate 1 to rise, and the gear 24 moves along the surface of the normal third tooth 5, so that the connecting plate 1 can move normally;

[0047] If there are problems with other groups of second teeth 4 that are not adjacent to the first tooth 3, at this time, move the position of the gear 24 back to a group of second teeth 4 that are not problematic below. Then replace the problematic second teeth 4 according to the above principle. Subsequently, the normal movement of the gear 24 can be guaranteed, and then the connecting plate 1 and the net cage can be driven to rise;

[0048] During the whole usage process, when the second tooth 4 has problems and causes the gear 24 to fail to move normally, the positions of the group where the problematic second tooth 4 is located and the group where the third tooth 5 is located can be replaced, so that the normal third tooth 5 can be located above the gear 24, thereby ensuring that the gear 24 can move normally subsequently, ensuring that the net cage can rise normally, and thus preventing the situation where the entire process cannot proceed smoothly due to problems with the teeth located at a high position, ensuring the normal progress of the work schedule;

[0049] In order to mark the problematic second tooth 4 for faster subsequent maintenance, when the gear 24 moves to the problematic second tooth 4, the gear 24 cannot continue to move along the second tooth 4, causing the drive shaft to fail to rotate normally. At this time, the drive member 23 cannot operate normally, and the current inside it increases instantaneously. At this time, the sensor 21 monitors the change in current, and then cooperates with the controller 22 to control the pump body 19 to start for a period of time and then stop. The pump body 19 works to pump out the ink in the box body 20 and inject it into the annular pipe 17, and then spray it onto the surface of the arc-shaped plate 6 through the spray pipe 18. The horizontal extension of the position of the ink on the surface of the arc-shaped plate 6 is the position of the problematic second tooth 4.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
