Self-elevating pinion-and-rack offshore oil-and-gas exploitation structure device

Abstract

The invention discloses a self-elevating pinion-and-rack offshore oil-and-gas exploitation structure device, and belongs to the technical field of ocean energy resources. The device comprises piles, alower platform and an upper platform. The lower platform comprises a multi-space three-trim cavity base plate and arc-shaped plates which are annularly and fixedly connected. The upper platform comprises a flat plate, guard railings, a wind power generation device, a solar power device, a life module, an operation platform, a plane take-off and landing platform and a signal tower. A pile foundation of each pile can move upwards or downwards relative to a cylindrical chamber. A two-way screw self-locking device is installed on the lower surface of an inner chamber of the lower platform. With the self-elevating pinion-and-rack offshore oil-and-gas exploitation structure device, the problem that the load is over high during transportation and installation, the platforms can be adjusted horizontally, the phenomenon that the pinion-and-rack mechanism and motors thereof are damaged because the load of the platforms is applied to a pinion-and-rack mechanism for a long time is avoided, the number of the motor is lessened, the cost of the motors is reduced, the requirements on model selection and the installation space of the motors are reduced, the space utilization ratio is high, the floor space is small, the operating depth is large, movement is flexible and stable to carry out, the safety is high, the device can adapt to different marine geologies, and the construction cost is low.

Description

technical field [0001] The invention belongs to the technical field of marine energy, and in particular relates to a jack-up rack and pinion offshore oil and gas exploitation structural device. Background technique [0002] The rapid development of the world economy has brought about a large amount of energy consumption, and oil and natural gas are still the main energy sources at present. Today, the shortage of onshore oil resources has become increasingly prominent, leading to a sharp decline in the world's oil and gas reserves. In order to meet the ever-increasing demand for energy, advanced countries in the world have focused on the development of oil and gas resources in the deep sea. Deep-sea oil platforms have become a hot spot in international ocean engineering research and development. There are two major development trends: one is to develop into water and ultra-deep water ; Second, to large-scale development. China is a large oceanic country, and its vast sea ar...

Problems solved by technology

[0006] The object of the present invention is to provide a self-elevating rack and pinion type marine oil and gas exploitation structure device, which solves the problem of excessive load of the lifting mechanism during the transportation and installation of the offshore oil and gas exploitation structure platform by using the buoyancy of the buoyancy on the lower surface of the inner cavity of the lower platform. Greatly reduce the number of transmission motors, cost, type selection and installation space requirements, with stable movement and high synchronization; and can realize the lowering of the lifting platform and level adjustment, avoiding the damage to the structure caused by the stress concentration caused by inclination, and adapting to different marine geology ; And the use of a two-way screw self-locking device with good self-locking performance solves the situation that the platform load is applied to the rack and pinion mechanism for a long time to cause damage to it and the motor, which can be quickly locked and has high safety.
