Description

Technical Field

[0001] The utility model relates to the technical field of deep - sea aquaculture, and particularly relates to an automatically - lifting cage for deep sea. Background Technique

[0002] Deep - sea cages are important equipment for marine aquaculture and marine scientific research, and their development background and technology have been continuously evolving and improving. With the increasing demand of humans for marine resources, deep - sea cages, as an effective marine aquaculture tool, have gradually attracted attention and been widely used. Traditional deep - sea cages mainly rely on manual operation for lifting, with low automation and potential safety hazards. Storm surges and huge waves caused by typhoons, tornadoes, etc. can cause destructive or even devastating blows to the aquaculture system of the cages. Strong winds and heavy rains can cause the cultured fish in the cages to collide, get scratched, and trigger secondary bacterial ulcer diseases and other diseases. Therefore, there is an urgent need to design a safe, reliable and highly automated anti - wind - and - wave deep - sea aquaculture cage to promote the transformation and development of the deep - sea aquaculture industry. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatically - lifting cage, which can control the automatic lifting of the cage according to the monitored weather conditions and ensure the safety and stability of the cage in the deep - sea environment.

[0004] To achieve the above - mentioned purpose, the solution of the utility model is:

[0005] An automatically - lifting cage includes a floating platform and typhoon - sensing floating bodies arranged around the floating platform. The floating platform is a hollow structure. A cage is arranged below the floating platform. Multiple groups of lifting mechanisms for controlling the lifting of the cage are arranged on the floating platform. The lifting mechanism includes a lifting motor, a driving pulley, a guiding pulley and a lifting rope. The output shaft of the lifting motor is connected to the driving pulley. The driving pulley is fixed on the floating platform through a driving - pulley seat. One end of the lifting rope is connected to the driving pulley, and the other end of the lifting rope is connected to the cage after passing around the corresponding guiding pulley. The guiding pulley is fixed on the floating platform through a guiding - pulley seat. Multiple groups of locking mechanisms for locking the driving pulley are also arranged on the floating platform. The locking mechanism includes a telescopic cylinder, a pin - hole runner and a locking wheel arranged oppositely. The piston rod of the telescopic cylinder is connected to the locking wheel. A plug pin is arranged on the surface of the locking wheel opposite to the pin - hole runner. A pin hole for the plug pin to pass through is penetrated through the pin - hole runner. The output shaft of the lifting motor passes through the driving pulley and is connected to the pin - hole runner. A controller is also arranged on the floating platform. The typhoon - sensing floating body is in signal connection with the controller. The lifting motor and the telescopic cylinder are in control connection with the controller.

[0006] A guardrail is provided along the perimeter of the top of the floating platform. The lifting motor and the driving pulley are located outside the guardrail, and the guiding pulley is located inside the guardrail.

[0007] Float balls are provided along the perimeter of the bottom of the floating platform. The net cage includes a net cage frame and a netting covering the net cage frame, and the netting is a basalt fiber netting.

[0008] There are four sets of lifting mechanisms, which are symmetrically arranged at the corners of the floating platform respectively. There are also four sets of locking mechanisms, and the locking mechanisms are arranged in one-to-one correspondence with the lifting mechanisms.

[0009] The output shaft of the lifting motor, the axles of the corresponding driving pulley, the pin hole runner and the locking wheel are all on the same straight line.

[0010] The lifting rope is a basalt fiber rope.

[0011] The driving pulley seat is a triangular support. The guiding pulley seat includes a first arm arranged vertically and a second arm forming an obtuse angle with the first arm. One end of the second arm extends towards the inside of the floating platform, and the guiding pulley is fixed on the corresponding second arm.

[0012] The pins on the locking wheel are serrated, and the shape of the pin holes on the pin hole runner is adapted to the shape of the pins, and the number of the pin holes is greater than the number of the pins.

[0013] After adopting the above structure, for an automatically lifting net cage of the present utility model, the typhoon sensing floating body senses the magnitude of the wind and waves on the sea surface and transmits the data signal to the controller. When the controller determines that the wind and waves are too large, it controls the lifting motor to work and lowers the net cage into the deep sea. When the net cage reaches the predetermined depth (the controller indirectly controls it by the number of turns of the lifting motor), the controller controls the telescopic cylinder to work, pushing the pins on the locking wheel to engage with the pin holes on the pin hole runner, thereby locking the driving pulley and ensuring the stability of the net cage. When the controller determines that the wind and waves have decreased somewhat, it controls the telescopic cylinder to work, retracting the pins on the locking wheel, releasing the lock on the driving pulley, and then controls the lifting motor to work to pull the net cage back to the sea surface again.

[0014] Therefore, for an automatically lifting net cage of the present utility model, it can control the automatic lifting of the net cage according to the monitored weather conditions, and can ensure the safety and stability of the net cage in the deep sea environment.

[0015] Furthermore, the netting is a basalt fiber netting, and the lifting ropes are basalt fiber ropes. Basalt fiber is known for its excellent mechanical properties and corrosion resistance. Its tensile strength far exceeds that of ordinary steel wires, ensuring the stable sinking of the net cage under extreme conditions. BRIEF DESCRIPTION OF THE DRAWINGS

Preferably, the net cage frame 41 is a square frame, and reinforcing diagonal bars 411 are also provided on each side of the square frame 41 to better shape the netting. The netting is a basalt fiber netting.

[0035] Multiple sets of lifting mechanisms for controlling the lifting of the net cage 4 are provided on the floating platform 1. Each set of lifting mechanisms includes a lifting motor 51, a driving pulley 52, a guiding pulley 53, and a lifting rope 54. Preferably, there are four sets of lifting mechanisms, and the lifting mechanisms are symmetrically arranged at the corners of the floating platform 1 respectively. The lifting motor 51 and the driving pulley 52 are located outside the guardrail 2, and the guiding pulley 53 is located inside the guardrail 2.

[0036] The output shaft of each set of lifting motors 51 and the axis of the corresponding driving pulley 52 are on the same straight line, parallel to the side of the floating platform 1, and the output shafts of the two lifting motors 51 on the same side of the floating platform 1 are arranged facing each other.

[0037] The output shaft of the lifting motor 51 is connected to the driving pulley 52. The driving pulley 52 is fixed on the floating platform 1 through a driving pulley seat 55. One end of the lifting rope 54 is connected to the driving pulley 52, and the other end of the lifting rope 54 is connected to the net cage 4 after passing around the corresponding guiding pulley 53. The guiding pulley 53 is fixed on the floating platform 1 through a guiding pulley seat 56. Preferably, the driving pulley 52 and the guiding pulley 53 are made of high-strength, low-friction, and corrosion-resistant metal materials, and can withstand the huge pulling force of the lifting rope 54 when the net cage 4 is lifted. Preferably, the driving pulley seat 55 is a triangular support, the driving pulley 52 is embedded at the vertex position of the driving pulley seat 55, the lifting motor 51 is fixed outside the driving pulley seat 55, and the output shaft of the lifting motor 51 passes through one side of the driving pulley seat 55 and the driving pulley 52 in sequence, and passes out from the other side of the driving pulley seat 55.

[0038] The guiding pulley seat 56 includes a vertically arranged first arm and a second arm forming an obtuse angle with the first arm. One end of the second arm extends towards the inside of the floating platform 1, and the guiding pulley 53 is embedded on the corresponding second arm.

[0039] Multiple sets of locking mechanisms for locking the driving pulley 52 are also provided on the floating platform 1. Preferably, there are also four sets of locking mechanisms, and the locking mechanisms are arranged in one-to-one correspondence with the lifting mechanisms.

[0040] Each locking mechanism includes a telescopic cylinder 61, a pin hole runner 62 and a locking wheel 63 which are oppositely arranged. The output shaft of each lifting motor 51 passes through one end of the driving pulley seat 55 and is connected to the corresponding pin hole runner 62. The piston rod of the telescopic cylinder 61 is connected to the locking wheel 63. The piston rod of the telescopic cylinder 61, the axes of the pin hole runner 62, the locking wheel 63 and the driving pulley 52 are all on the same straight line.

[0041] On the surface of the locking wheel 63 opposite to the pin hole runner 62, there is a bolt 631. The pin hole runner 62 is penetrated with a pin hole 621 for the bolt 631 to pass through. Preferably, the bolt 631 on the locking wheel 63 is in a tooth shape, and the shape of the pin hole 621 on the pin hole runner 62 is adapted to the shape of the bolt 631, and the number of the pin holes 621 is greater than the number of the bolts 631, so as to ensure that no matter what angle the pin hole runner 62 rotates to, the bolt 631 of the locking wheel 63 can be inserted into the pin hole 621 of the pin hole runner 62.

The typhoon sensing floating bodies 8, the lifting motors 51, the telescopic cylinders 61 and the controller in the present utility model are all well-known components in the art.

[0043] After adopting the above structure, an automatically lifting fish cage of the present utility model, as Figure 1 、 Figure 2 Figure 4 and Figure 5 shown, senses the magnitude of the wind and waves on the sea surface through the typhoon sensing floating bodies 8 and transmits data signals to the controller. When the controller determines that the wind and waves are too large, it controls the lifting motors 51 to work and lowers the fish cage 4 into the deep sea. When the fish cage 4 reaches the predetermined depth (the controller indirectly controls by the number of turns of the lifting motors 51), the controller controls the telescopic cylinders 61 to work, and pushes the bolt 631 on the locking wheel 63 to be inserted into the pin hole 621 on the pin hole runner 62, so as to lock the driving pulley 52 and ensure the stability of the fish cage 4. When the controller determines that the wind and waves have decreased, it controls the telescopic cylinders 61 to work, retracts the bolt 631 on the locking wheel 63, releases the locking of the driving pulley 52, and then controls the lifting motors 51 to work to pull the fish cage 4 back to the sea surface again.

[0044] Therefore, the present utility model provides an automatically lifting net cage which can control the automatic lifting of the net cage 4 according to the monitored weather conditions and ensure the safety and stability of the net cage 4 in the deep-sea environment.

[0045] Furthermore, the netting is a basalt fiber netting, and the lifting rope 54 is a basalt fiber rope. Basalt fiber is renowned for its excellent mechanical properties and corrosion resistance, and its tensile strength far exceeds that of ordinary steel wires, which can ensure the stable sinking of the net cage 4 under extreme conditions.

Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
