Description

Technical Field

[0001] The utility model relates to the field of offshore aquaculture, and particularly to a lifting device for a jacket enclosure net. Background Art

[0002] Under the background of the global clean energy transformation, offshore wind power, with its unique advantages, has become an important force in promoting the transformation of the energy structure. However, the traditional single wind farm construction mode occupies valuable marine space to a large extent, which not only affects the protection of the marine environment but also restricts the sustainable development of offshore wind power. At the same time, deep-sea aquaculture, as an emerging aquaculture method, aims to meet the human demand for high-quality seafood while reducing the overexploitation of inshore resources. However, due to the need for sufficient strength and stability of deep-sea aquaculture cages to withstand harsh sea conditions, the construction and maintenance costs of aquaculture facilities are high, restricting the development of deep-sea aquaculture. Against this background, the jacket enclosure net aquaculture mode emerged, that is, by adding a netting system for aquaculture on the jacket of an offshore wind power device, using the stable structure of the jacket to create a stable aquaculture space. In this way, the jacket can not only support the safe operation of the wind turbine but also provide a solid support platform for seawater aquaculture, realizing the diversified utilization of marine space.

[0003] Currently, the netting system of an offshore jacket has an enclosure net and an enclosure net lifting and installation device. The enclosure net lifting and installation device includes net mouth ropes and net bottom ropes. Net bottom ropes are installed at the four corners of the bottom of the enclosure net, and the four net bottom ropes are respectively installed at the lower parts of four jackets. Net mouth ropes are installed at the four corners of the mouth of the enclosure net, and the four net mouth ropes are respectively installed at the upper parts of the four jackets and are on the sea surface. However, when operating such as harvesting or inspecting, the four net mouth ropes and net bottom ropes of this structure of the enclosure net lifting and installation device need to be lifted upward together. In this way, during the lifting process, it is easy to cause the aquaculture space of the enclosure net to change, thereby affecting the aquaculture organisms.

[0004] In view of this, the inventor of this case conducted in-depth research on the above problems, and thus this case was born. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic lifting device for a jacket enclosure net to solve the problem that the aquaculture space will change during the lifting process of the existing net enclosure, affecting the aquaculture organisms.

[0006] To achieve the above purpose, the utility model adopts the following technical solution:

[0007] An automatic lifting device for a jacketed enclosure net, comprising net mouth pull ropes installed at the four corners of the net mouth of the enclosure net and net bottom pull ropes installed at the four corners of the net bottom of the enclosure net. It also includes a walking platform. The walking platform is a hollow annular frame. The hollow annular frame is installed on four jacket frames and is on the sea surface. The enclosure net is within the hollow range of the hollow annular frame. At the positions of the four net mouth pull ropes on the upper surface of the walking platform, there are rope winding devices. The rope winding devices have a first rope winding cylinder, a rope passing wheel, and a second rope winding cylinder. The first rope winding cylinder and the second rope winding cylinder are rotationally installed.

[0009] A bracket is installed on the walking platform corresponding to each rope winding device. The first rope winding cylinder and the second rope winding cylinder are rotationally installed on the bracket.

[0010] The bracket has a lower bottom plate installed on the walking platform and vertical plates vertically arranged on the lower bottom plate and spaced transversely relative to each other. A main shaft is provided between the two vertical plates. The two ends of the main shaft are correspondingly installed on the two vertical plates. The first rope winding cylinder and the second rope winding cylinder are movably sleeved outside the main shaft, and a locking device for restricting the first rope winding cylinder and the second rope winding cylinder from translating along the axial direction of the main shaft is installed outside the main shaft.

[0011] The locking device has a first clamp and a second clamp. The first clamp and the second clamp are respectively sleeved and fixed outside the main shaft, and the first rope winding cylinder and the second rope winding cylinder are clamped between the first clamp and the second clamp.

[0012] Both the first rope winding cylinder and the second rope winding cylinder have a central rotating shaft and a rope winding drum sleeved outside the central rotating shaft. The two central rotating shafts are both sleeved outside the main shaft and are transversely relatively arranged. And the opposite ends of the two central rotating shafts both have extension segments extending outside the rope winding drum. Conical gears are sleeved outside the two extension segments. The rotation driving device is a motor driving device for driving the two conical gears to rotate synchronously and in different directions.

[0013] The above-mentioned motor drive device has a servo motor and a driving bevel gear. The servo motor is horizontally installed, and the horizontal direction of the servo motor is perpendicular to the axial direction of the main shaft. The output shaft of the servo motor extends between the two bevel gears, and the driving bevel gear is sleeved on the output shaft of the servo motor.

During the lowering process, the enclosure net is always tightened by the four net mouth pulling ropes and the four net bottom pulling ropes, and the cultured space of the enclosure net remains unchanged.
