[0002] As a leading project in the layout of deep-sea aquaculture industry, marine fishery aquaculture vessels are forward-looking, leading and exemplary in industrial development and technological innovation and application. Aquaculture vessels need to be equipped with special cranes to carry out daily feed transportation, fish catching in the cabin, hatch cover handling, refrigerated container handling and other operations on aquaculture vessels.

[0003] After searching, the utility model with Chinese patent announcement number CN219363057U discloses a full-rotating crane for marine fishery breeding vessels, which includes a base, a tower body, a slewing mechanism, a slewing bearing, and a boom. The slewing mechanism is installed on the tower body, and the end of the boom is hinged to the tower body. A luffing cylinder is installed between the boom and the tower body. The two ends of the luffing cylinder are respectively connected to the boom and the tower body, and the luffing of the boom is achieved by extending and retracting the luffing cylinder.

[0004] The above-mentioned device is used in the marine environment. Seawater is highly corrosive to metals, and the cables inevitably need to come into contact with seawater. When seawater exists in the gaps for a long time, it will accelerate the aging of the cables, and there is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a crane for marine aquaculture includes a bracket 1, which is characterized in that: a moving rod 3 is slidably inserted at one end of the top of the bracket 1, and a cleaning component 5 is installed at one end of the moving rod 3. The cleaning component 5 includes a connecting rod 501 fixedly connected to the top outer wall of the moving rod 3, and a fixed pipe 502 is fixedly connected to the bottom outer wall of the connecting rod 501. The fixed pipe 502 is rotatably sleeved with a rotating pipe 503, and a plurality of nozzles 504 distributed at equal distances are arranged on the bottom outer wall of the rotating pipe 503, and the bottom ends of the plurality of nozzles 504 are arranged close to each other, and an air inlet is arranged on the top outer wall of the fixed pipe 502.

[0025] A motor 505 is fixedly mounted on the top outer wall of the fixed tube 502, and a gear 506 is coaxially fixed on the output end of the motor 505. A gear ring 507 is fixedly sleeved on the top of the circumferential outer wall of the rotating tube 503, and the gear ring 507 is meshed with the gear 506.

[0026] A winder is provided on the outer wall of one side of the bracket 1, and the cable of the winder is wrapped around the inside of the bracket 1, and the cleaning component 5 is surrounded outside the cable.

[0027] The external air supply device is started, and the air flow enters the fixed tube 502, and then is ejected downward through the rotating tube 503 and multiple nozzles 504. When the moving cables are blown by the air flow, the seawater in the gaps between the cables will be intercepted and fall to the lower position. Then, the gear 506 is driven to rotate by starting the motor 505, and the gear 506 drives the rotating tube 503 to rotate through the gear ring 507 meshing with it, and then the air flow ejected from the nozzle 504 will continue to rotate, thereby greatly increasing the blowing area and helping to improve the cleaning effect.

[0028] like Figure 2 and Figure 4 As shown, a support plate 2 is coaxially fixed to one end of the bottom of the bracket 1 , and a support assembly 6 is installed on the top of the support plate 2 .

[0029] The supporting assembly 6 includes two limit frames 601 fixedly connected on both sides of the outer wall of the top of the supporting plate 2, and an extension frame 602 is slidably connected inside the two limit frames 601. One end of the two extension frames 602 is threadedly connected with a screw rod 603, and the two ends of the two screw rods 603 are rotatably connected to the inner walls on both sides of the two limit frames 601 respectively. The two screw rods 603 are fixedly sleeved with a gear ring 2 604, and a motor 2 606 is fixedly installed on the outer wall of one side of the bracket 1. The motor 2 606 shaft fixing sleeve is provided with two gear rings 3 605, and the two gear rings 3 605 are respectively meshed with the two gear rings 2 604.

[0030] like Figure 2As shown, both ends of the two extension frames 602 are threadedly connected with a screw rod 607, and one end of the bottom of the multiple screw rods 607 is rotatably connected with a support block, so that the extension frames 602 can better fit the deck, which is conducive to ensuring the supporting effect.

[0031] If the cargo to be hoisted is heavy, the two gear rings three 605 can be driven to rotate by starting the motor two 606. The two gear rings three 605 can drive the two screw rods 603 to rotate synchronously through the two gear rings two 604 meshing therewith. The extension frame 602 restricted by the limit frame 601 will be driven by the screw rod 603 to extend outward, and then the screw rod 607 is rotated to make one end of it contact the ground, thereby increasing the area of ​​the support plate 2, ensuring that the state of the device is more stable, and there will be no problem of tilting due to insufficient support effect.

[0032] like Figure 1 and Figure 2 As shown, a hydraulic cylinder 4 is fixedly installed on the top outer wall of the bracket 1, and the output end of the hydraulic cylinder 4 is fixedly connected to one end of the moving rod 3. When the hydraulic cylinder 4 is started, the moving rod 3 can be driven to extend out of the bracket 1.

[0033] The utility model provides a crane for marine aquaculture, and the specific working principle is as follows:

[0034] When the device is working, the reel outside the bracket 1 starts to reel in the cable, and at the same time, the external air supply device is started, and the airflow enters the fixed tube 502, and then is ejected downward through the rotating tube 503 and multiple nozzles 504. When the moving cable passes through the airflow, the seawater in the gap between the cables will be intercepted and fall to the lower position, and then the gear 506 is driven to rotate by starting the motor 505. The gear 506 drives the rotating tube 503 to rotate through the gear ring 507 meshing with it, and then the airflow ejected from the nozzle 504 will continue to rotate, thereby greatly increasing the blowing speed. The sweeping area is beneficial to improving the cleaning effect. If the cargo to be hoisted is heavy, it is only necessary to start the motor 2 606 to drive the two gear rings 3 605 to rotate. The two gear rings 3 605 can drive the two screw rods 603 to rotate synchronously through the two gear rings 2 604 meshing therewith. The extension frame 602 restricted by the limit frame 601 will be driven by the screw rod 603 to extend outward, and then the screw rod 607 is rotated to make one end of it contact the ground, thereby increasing the area of ​​the support plate 2, ensuring that the state of the device is more stable, and there will be no problem of tilting due to insufficient support effect.

[0035] 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.
