A light, self-floating, elevated structure that can be erected by manpower

Abstract

The elevated structure, which is light, self-floating, and can be erected manually, is a new type of equipment suitable for shallow water areas without power supply conditions in the open sea. When in use, use ships and other vehicles to transport the equipment to the sea area near the erection area, first flood the airtight box, drag the airtight box together with the legs to the erection area, install or connect the legs and the foundation plate, and lower the legs , install the guide pulley and manual hoist, and connect the chain and the chain drive, then pull the manual hoist to lift the closed box, and control the lifting speed of each manual hoist (or install a manual hydraulic device, and connect the oil cylinder, and then rely on manual operation Manual oil pump to lift the case). It is characterized by its light structure, which can be transported by ships to the open sea for flooding and self-floating, and can be erected manually in shallow water areas without power supply such as electricity.

Description

technical field [0001] The present invention relates to an elevated structure (or elevated platform, the same below), especially the building units of the elevated elevated structure, which are light, self-floating and can be erected manually. Background technique [0002] It is relatively convenient and fast to build and assemble floating structures on the water, but the wave adaptability of floating structures is limited. The elevated structure above the water has a certain height above the water surface, and the upper structure is no longer subject to wave loads, which can effectively improve its anti-wave capability, but the engineering volume of the construction is relatively large, especially in shallow water areas, where large construction ships cannot enter, and construction is relatively difficult. It is difficult, and it is impossible to realize the rapid construction of elevated structures in the open sea environment without power supply such as electricity. [0...

Problems solved by technology

The elevated structure above the water has a certain height above the water surface, and the upper structure is no longer subject to wave loads, which can effectively improve its anti-wave capability, but the engineering volume of the construction is relatively large, especially in shallow water areas, where large construction ships cannot enter, and construction is relatively difficult. It is difficult, and it is even impossible to realize the rapid construction of elevated structures in the open sea environment without power supply such as electricity

[0003] The usual water elevated structures include jack-up offshore platforms, wind power installation ships and elevated trestles, etc. Jack-up offshore platforms and wind power installation ships have a large draft and cannot be constructed in shallow waters, and their construction costs are also high

The existing elevated trestle structure has a large dead weight, and generally relies on towage to achieve sea transportation, which cannot realize high-sea ship transportation. The leg lifting mechanism is generally hydraulic or rack rotation mechanism, etc., and the erection and withdrawal processes require corresponding It is not suitable for application in open sea conditions
