Problems solved by technology
However, due to the particularity of the seabed working environment, such as ocean currents, seabed visibility, seawater vibration, etc., it has brought great problems to the deployment of underwater equipment.
For the decentralized installation, humans have done a lot of thinking and design, such as designing the guiding mechanism on the production equipment, assisting the installation of underwater robots, etc., but a single guiding mechanism is not enough to install the production equipment correctly, multiple guiding must be set, and The unreasonable and underwater guiding mechanism will affect the follow-up installation work, and other reasons have brought great difficulties to the installation of production facilities

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The invention provides a guide column suitable for underwater equipment installation, the guide column includes an unlocking mechanism and a fixing mechanism, wherein the unlocking mechanism includes a guide head, an unlocking head, a push block, a plug column, and an outer cylinder , a support ring, an end cover, a rectangular spring, a large nut, a cylinder cover, two eyebolt screws, several screws, the fixing mechanism includes a fixed base, four pins, four positioning sleeves, four springs, Four end caps, some screws. After the guide column is lowered, it is inserted into the fixed base, and the four guide blocks on the outer wall of the outer cylinder can cooperate with the four positioning grooves on the top surface of the base to provide positioning; when lowering, the chamfer at the bottom of the outer cylinder can cont...

The invention provides a guide column suitable for underwater equipment installation. An unlocking mechanism is used for unlocking the guide column, and a fixing mechanism is used for fixing the guide column; the guide column can be unlocked by applying axial force to a locking mechanism; a supporting ring is connected with an outer cylinder through a lifting bolt and used for ensuring the coaxiality of a top column during movement; four arch-shaped holes are formed in the side wall of the outer cylinder, and the bottom surfaces of the arch-shaped holes are designed to be inclined surfaces; the lower surface of the extending end of a spring bolt in the fixing mechanism is designed to be an inclined surface, a spring can be extruded to retract under stress, and the upper surface of the extending end of the spring bolt is a trapezoidal surface; and four guide blocks are arranged on the outer wall surface of the outer cylinder and matched with a base to provide positioning. When the guide column is lowered, the spring bolt is jacked back by the outer cylinder through gravity, and after the guide column is completely lowered to the base, the spring bolt is inserted into the arch-shaped holes to lock the guide column; and the axial force is applied to an unlocking head, so that the top column moves downwards to jack back the spring bolt to unlock the guide column, the guide column has higher stability in the working process through the locking and unlocking functions, and the engineering quality is improved.
Description
technical field [0001] The invention relates to a guide column, in particular to a guide column suitable for underwater equipment installation. Background technique [0002] Oil and natural gas are non-renewable resources. With the massive consumption of human beings, the limited oil and natural gas resources on land can no longer meet the growing needs of human beings. Therefore, the exploration and development of offshore oil and gas resources have become the focus and focus of industrial countries in the world. . Although my country's offshore oil and gas development capability has made a qualitative leap after decades of hard work, compared with developed countries, its offshore oil and gas exploration and exploitation capabilities are still relatively insufficient. At present, the proven rate of my country's offshore crude oil is less than 20%, the proven rate of natural gas is less than 10%, and 70% of oil and gas reserves are located in deep waters. In the three maj...
