Description

Seawater lifting device
Technical Field
The utility model relates to the field of ocean vessels, in particular to a seawater lifting device.
Background
The traditional seawater lifting system is mainly used for the traditional jack-up drilling platforms (CJ 46, CJ50, JU2000 and the like) and Liftbottom and other projects, the submersible pump is arranged on the pile leg, and the upper flange is connected with the carbon steel seawater vertical pipe. When the platform is lifted to the working height, connecting the reserved interface on the vertical pipe with a ship body seawater pipeline by using a hose; and when the platform is moved, the hose is removed.
The seawater lifting system in the form is low in automation degree, the submersible pump is fixedly arranged on the pile leg, daily inspection and maintenance are inconvenient, a crane with long boom and heavy crane is required to be used for lifting, the boom is too close to the pile leg, the operation is inconvenient to develop, the platform is required to be lifted to a certain height, and the lifting hook is ensured to be higher than the pile leg to be operated. The main crane of the deck of the platform is generally used, so that more platform resources are occupied. Special cable winding winch is needed to be equipped to ensure the cable storage under the working condition. When the pile leg is received in the surrounding well, most of the vertical pipe is positioned above the main deck, and the cable length is longest; during working conditions, the long cable is not needed, and redundant cables are stored on the winch. The cable length is about twice that of the sea water riser, increasing procurement costs. Too much cable winding can influence the radiating effect, and the cable current-carrying capacity reduces, can increase the diameter demand of selecting type cable.
In recent years, a hose winch type seawater lifting system has a better truss pile leg type wind power installation platform market. The traditional seawater lifting system is basically distinguished from the project, a hose winch type seawater lifting system is selected, and the available area of a deck is occupied. The wind power installation self-elevating platform main deck is used for storing the loading capacity of fan blades, fan cabins, hubs or other cargoes, and the applicable area requirement of the shipper on the main deck is high. The choice of this form of lifting system presents challenges to the main deck layout and design. In stormy weather, the hose and cable are easily rubbed and damaged with the chord edge of the ship bottom plate. The use conditions are limited. When the wind speed is more than 20 meters/s and less than 36 meters/s, the platform is in a pile standing operation state (the crane does not work), and the submersible pump is required to work normally at the moment, so that the winch-type seawater lifting system cannot meet the requirement.
Seawater tower seawater lifting system the seawater tower seawater lifting system solves part of the drawbacks of the second seawater lifting system, presenting obvious advantages, but also presents some problems of its own. The weight and the center of gravity are large. The weight of a hose winch in a construction project is about 12 tons, and the weight of a seawater tower is 54 tons and exceeds 350 percent; and the height of the center of gravity increases considerably. The length of the cable is increased, and redundant cables and hoses need to be piled up on a main deck or are matched with separate hose winches and cable winches when working under the working condition of the maximum air gap. The occupied deck area is increased compared with a hose winch type seawater lifting system, and a surrounding well is designed on a main deck. Because the accessories of the lifting system are high-strength thick plates, the holes are not allowed to be drilled at will, the surrounding well of the seawater tower has larger influence on the deck area, and the occupied deck area is about 50m < 2 >.
In addition, in the disclosed CN 201811280244-a suitable self-elevating platform sliding seawater lifting device, the device comprises a pile-flushing pipe and a submersible pump, the pile-flushing pipe is provided with a sliding guide rail, the submersible pump is connected with a submersible pump tower pipe through a flange, the top of the submersible pump tower pipe is provided with a sliding lifting lug, a plurality of sliding clamping grooves are arranged between the submersible pump tower pipe and the pile-flushing pipe, the sliding clamping grooves are uniformly distributed on the submersible pump tower pipe and fixedly connected with the submersible pump tower pipe, the sliding clamping grooves are in sliding connection with the sliding guide rail, as shown in the drawing in the comparison document, more sliding clamping grooves are arranged on the tower pipe, and because the device is positioned on the seabed for a long time, a large number of marine organisms are on the guide rail, the number of sliding clamping grooves is larger, the stress area between the guide rail is increased, the friction is increased, the resistance between the marine organisms and the guide rail is increased, the sliding clamping grooves are easy to cause damage, and the number of sliding clamping grooves is matched with the guide rail, so that the requirement on the perpendicularity of the guide rail is higher. The submersible pump power cable storage winch needs to be arranged, the platform area is occupied, the automation degree of the system is low, and the operation flow is complex.
