Description

Technical Field

[0001] This application relates to the field of fixed aquaculture cage technology, and more specifically, to a fixed aquaculture cage hoisting and submerging system. Background Technology

[0002] Currently, fixed aquaculture cages are typically transported by semi-submersible vessels and positioned underwater by floating cranes. To improve the stability of the cages during descent, auxiliary airbags are usually attached to them. The buoyancy of the airbags is adjusted by inflating and deflating them, thus adjusting the cage's descent posture. However, existing technologies typically adjust the buoyancy of the airbags by manually operating the valves on-site. This results in a lag in the adjustment process and poses a high risk and safety hazard due to the high degree of manual operation.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0034] The "multiple" mentioned in the embodiments of this application refers to two or more.

[0035] like Figure 1As shown in the embodiment of this application, the fixed aquaculture cage lifting and lowering cylinder is used for lifting and lowering aquaculture cages. A top ring platform 100 is provided at the top of the aquaculture cage, and a bottom ring beam is provided at the bottom. Several airbags are installed at the bottom ring beam. By adjusting the buoyancy of the airbags, the lowering posture of the aquaculture cage is adjusted to achieve lifting and lowering. The lifting and lowering system includes an air compressor 300 and airbag control units. The air compressor 300 is installed on the top ring platform 100 to ensure stable operation and provide an air source. At least two airbag control units are installed on the top ring platform 100, and each airbag control unit is connected to the air compressor 300, allowing the air compressor 300 to inflate the corresponding airbag through each airbag control unit. Each airbag control unit includes an electric control valve group that can control the corresponding airbag. The airbags are inflated and deflated to adjust the buoyancy of the corresponding airbags. The airbag control unit also includes a pressure detection module, which is connected to the airbags and can detect their pressure values. The airbag control unit also includes a slave control box 416, which is connected to an electric control valve group. This allows the slave control box 416 to adjust the opening degree of each electric control valve in the electric control valve group. The slave control box 416 is communicatively connected to the pressure detection module and to the main control console 500, allowing the main control console 500 to obtain the pressure values ​​of each airbag. In this way, by detecting the pressure values ​​of the airbags through the pressure detection module and obtaining the pressure values ​​of the airbags through the main control console 500, the opening degree of the corresponding electric control valve is adjusted to achieve real-time adjustment of the airbag buoyancy, improving the efficiency of airbag buoyancy adjustment. Furthermore, by adjusting the airbags through electric control valves, the safety hazards during the submersion of the aquaculture cages are reduced.

[0036] It should be noted that the top ring platform 100 of the aquaculture cage is the top structure of the aquaculture cage, which can provide a safe and stable walking and operating platform; the bottom ring beam of the aquaculture cage is a ring structure that forms the bottom frame of the aquaculture cage. The bottom ring beam can correspond vertically with the top ring platform 100 so that the netting of the aquaculture cage can be stretched to form an aquaculture net bag with sufficient capacity, which is the basis for the underwater stability of the aquaculture cage. By setting airbags on the bottom ring beam, controllable buoyancy can be directly applied to the bottom ring beam to improve the stability of the aquaculture cage during the hoisting and submersion process.

[0037] like Figures 1-2As shown, the airbag control unit includes a first airbag control unit 401, a second airbag control unit 402, a third airbag control unit 403, and a fourth airbag control unit 404. The first airbag control unit 401, the second airbag control unit 402, the third airbag control unit 403, and the fourth airbag control unit 404 are respectively located in the four corner areas of the top ring platform 100, and the air compressor 300 is located in the edge area of ​​the top ring platform 100, so that the force distribution of the entire aquaculture cage is relatively uniform.

[0038] like Figure 2 As shown, each airbag control unit is used to control two airbags. Specifically, the first airbag control unit 401 adjusts the first airbag 201 and the second airbag 202; the second airbag control unit 402 adjusts the third airbag 203 and the fourth airbag 204; the third airbag control unit 403 adjusts the fifth airbag 205 and the sixth airbag 206; and the fourth airbag control unit 404 adjusts the seventh airbag 207 and the eighth airbag 208. The corresponding airbags are distributed near the corresponding airbag control units, so that each airbag is distributed sequentially along the periphery of the aquaculture net cage and surrounds the aquaculture net cage. This allows the first airbag 201, the second airbag 202, the third airbag 203, the fourth airbag 204, the fifth airbag 205, the sixth airbag 206, the seventh airbag 207, and the eighth airbag 208 to provide uniform buoyancy to the aquaculture net cage. The posture of the aquaculture net cage can be adjusted by controlling the buoyancy of the airbags at different positions, thereby improving the stability of the aquaculture net cage during the hoisting and submersion process.

[0039] like Figure 1 As shown, the structures of the first airbag control unit 401, the second airbag control unit 402, the third airbag control unit 403, and the fourth airbag control unit 404 of the hoisting and diving system provided in this application embodiment are all the same. Here, the structure of the first airbag control unit 401 will be specifically described.

[0040] like Figures 2-5As shown, the airbag control unit includes an air distribution manifold 411, a first electric control valve 412, a second electric control valve 413, a third electric control valve 414, and a fourth electric control valve 415. The air distribution manifold 411 is connected to an air compressor 300 via a high-pressure hose to provide air for inflation. The first end of the first electric control valve 412 is connected to the air distribution manifold 411, and the second end of the first electric control valve 412 is connected to the first end of the first airbag 201, so that the air distribution manifold 411 can supply air to the first airbag 201 via the first electric control valve 412. The airbag 201 is inflated. The first end of the second electric control valve 413 is connected to the second end of the first airbag 201. The second end of the second electric control valve 413 is connected to the external environment through a pipeline, so that the first airbag 201 can be deflated through the second electric control valve 413. In this way, when it is necessary to adjust the buoyancy of the first airbag 201, the pressure value inside the first airbag 201 can be adjusted by controlling the opening of the first electric control valve 412 and the second electric control valve 413, thereby achieving the adjustment of the buoyancy of the first airbag 201.

[0041] The first airbag control unit 401 simultaneously adjusts the second airbag 202. The first end of the third electric control valve 414 is connected to the air distribution manifold 411, and the second end of the third electric control valve 414 is connected to the first end of the second airbag 202, allowing the air distribution manifold 411 to inflate the second airbag 202 through the third electric control valve 414. The first end of the fourth electric control valve 415 is connected to the second end of the second airbag 202, and the second end of the fourth electric control valve 415 is connected to the external environment through a pipeline, allowing the second airbag 202 to deflate through the fourth electric control valve 415. Thus, when the buoyancy of the second airbag 202 needs to be adjusted, the opening degree of the third electric control valve 414 and the fourth electric control valve 415 is controlled to adjust the pressure value inside the second airbag 202, thereby achieving buoyancy adjustment of the second airbag 202.

[0042] like Figures 3-5 As shown, the slave control box 416 is electrically connected to the first electric control valve 412, the second electric control valve 413, the third electric control valve 414, and the fourth electric control valve 415, so as to control the opening degree of each electric control valve through the slave control box 416 to adjust the buoyancy of the corresponding airbag.

[0043] In this application, the airbag is equipped with a pressure measurement interface. The pressure detection module includes a pressure sensor and a pressure transmitter digital display 417. The pressure sensor is connected to the pressure measurement interface of the airbag so that the pressure value inside the airbag can be obtained in real time. The pressure value is obtained by connecting the pressure sensor through the pressure transmitter digital display 417 and connecting the slave control box 416 through the pressure transmitter digital display 417 so that the pressure value of the corresponding airbag can be transmitted to the main control console 500 through the slave control box 416.

[0044] It should be noted that the pressure sensor can be a piezoresistive pressure sensor. The gas pressure inside the airbag acts on the pressure diaphragm of the sensor. Changes in the gas pressure inside the airbag cause changes in the pressure acting on the sensor, thereby enabling the pressure sensor to obtain the pressure value inside the airbag.

[0045] To ensure the initial state of the airbag, the airbag control unit provided in this application embodiment also includes a mechanical control valve group. The airbag is equipped with a mechanical quick-connect interface that interfaces with the mechanical control valve of the mechanical control valve group. The mechanical control valve is connected to the airbag through the mechanical quick-connect interface so as to perform initial debugging and inflation test of the airbag through the mechanical control valve to ensure the airbag's sealing performance. At the same time, when the electric control valve group malfunctions and cannot work, the mechanical control valve group ensures the normal operation of the airbag.

[0046] like Figure 4 As shown, the mechanical control valve group includes a first mechanical control valve 418 and a second mechanical control valve 419. The first mechanical control valve 418 is connected to the first airbag 201, and the second mechanical control valve 419 is connected to the second airbag 202, so as to provide backup for the operation of the first airbag 201 and the second airbag 202.

[0047] like Figures 3-5 As shown, the airbag control unit is supported by a support frame 420, which is fixed on the top ring platform 100 to support the various components of the airbag control unit and ensure the stable operation of the airbag control unit.

[0048] The lifting and submersible system provided in this application embodiment also includes a floating crane vessel. The floating crane vessel follows the aquaculture cage and is at a certain distance from the aquaculture cage. The main control console 500 is set on the floating crane vessel. The slave control box 416 of each airbag control unit is connected through the main control console 500 to realize the buoyancy adjustment of each airbag.

[0049] Specifically, such as Figure 6 As shown, the main control console 500 has an electric control valve adjustment button 510 and a display screen 520. Through the communication connection between the main control console 500 and each slave control box 416, the display screen 520 of the main control console 500 can display the opening value of each electric control valve and the pressure value of each airbag for real-time monitoring. Furthermore, by adjusting the corresponding electric control valve adjustment button 510, the opening of the corresponding electric control valve can be adjusted.

[0050] The diagram uses the first airbag 201 as an example. H1-A corresponds to the first electric control valve 412, and H1-B corresponds to the second electric control valve 413. By adjusting H1-A and H1-B, the inflation and deflation of the first airbag 201 can be adjusted to regulate the pressure value of the first airbag 201.

[0051] like Figure 6 Each electric control valve adjustment button 510 corresponds to one of the electric control valves, which will not be described in detail here.

[0052] In practice, a network switch can be set up on the top ring platform 100. The slave control boxes 416 of each airbag control unit can be connected to the network switch first, and then connected to the main control console 500 through the network switch to ensure the stability of data transmission.

[0053] During the operation of the fixed aquaculture cage hoisting and submerging system provided in this application embodiment, the pressure value of each airbag is detected by the pressure detection module, and the opening degree of the corresponding electric control valve is adjusted by the pressure value obtained by the central control console 500 to realize real-time adjustment of the airbag, thereby improving the efficiency of airbag buoyancy adjustment, and reducing safety hazards by adjusting through electric control valves.

[0054] The above description of the embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
