Description

Semi-submersible type carrying and maintaining platform

Technical Field

The utility model belongs to an underwater operation device relates to a semi-submerged formula delivery maintenance platform.

Background

In underwater operation, the test platform is widely applied to the fields of ocean monitoring, resource exploration, ocean tests, underwater defense and the like, and can carry various complex test devices to complete underwater operation tasks. In marine surveying, the collected data can be adversely affected by various interference factors, and a nonmagnetic test platform is generated in order to reduce the interference factors. At present, most of non-magnetic test platforms are made of PVC, acrylic and glass fiber reinforced plastics, wherein the glass fiber reinforced plastics are used, and the non-magnetic test platforms are good in non-magnetic effect, high in hardness and strong in scratch resistance and wear resistance.

When the non-magnetic test platform is adopted for underwater operation, a common problem exists, namely, the non-magnetic test platform is not made of metal and has poor toughness because the non-magnetic material is made of non-magnetic material, when various devices are carried to discharge water, the non-magnetic test platform can be damaged or even broken off from the non-magnetic test platform due to weight increase or counterweight inclination, economic losses such as loss of the device and damage of the platform are caused, unexpected consequences can be brought to a test result, and even test failure is caused.

In order to reinforce no magnetism test platform, the mode of tie up the reinforcement has usually been taken, consolidates test platform base, and this kind of mode has although obtained certain effect, still has two shortcomings, and the reinforcement that first ties up receives the rivers influence to drop easily. Secondly, the dead weight and the area of the head-on flow of the platform are increased, and the stress of the platform is increased when the water flow changes the direction, so that the test effect is influenced.

Disclosure of Invention

The utility model provides a semi-submersible type delivery maintenance platform provides corollary equipment, convenient experiment for installation, transportation, use, the depositing of test platform especially no magnetism test platform, plays safety guarantee's effect.

The utility model provides a technical scheme that technical problem adopted is:

a semi-submersible type carrying and maintaining platform is characterized in that the semi-submersible type carrying and maintaining platform is divided into an upper part and a lower part, wherein the upper part is a carrying deck, and the lower part is a floating and submerging pile; four floating and submerging piles are taken as fulcrums, and a loading deck is welded on the four floating and submerging piles; the floating and submerging pile is in a cylindrical hollow structure, and is internally provided with an electric pump and a high-pressure electromagnetic valve which are connected and controlled by a cable.

Two slideways are longitudinally laid on the surface of the carrying deck; a moon pool is arranged in the middle of the carrying deck, winches are arranged on two sides of the long end of the carrying deck, and the winches are provided with ropes; the two sides of the deck are provided with brackets, the brackets are integrally trapezoidal, and the middle of the brackets is formed by a stainless steel pipe equilateral triangle;

the carrying deck is provided with a nonmagnetic test platform, the floating and submerging piles provide buoyancy for the semi-submersible type carrying and maintaining platform, the support reinforces the deck and fixes the test platform, the slideway loads the test platform, the winch is used for separating and returning the test platform, and the moon pool is used for function expansion or a test platform maintenance site.

The utility model overcomes there is not magnetic test platform easy damaged cracked problem when leaving water, adopts semi-submerged formula delivery maintenance platform, but the at utmost provides all-round protection, and the size is big, light in weight, cost are low, and the area of catching wind on water is little, and anti-wind ability is strong, and wave bending moment is little under water, and anti-wave ability is strong, and the navigation resistance is little, and the towing is easily controlled.

Detailed Description

The following describes in detail specific embodiments of the present invention with reference to the drawings and technical solutions.

The method comprises the steps of fixing a nonmagnetic test platform on a slideway of a semi-submersible carrying and maintaining platform by taking a Dinima rope as a rope, additionally installing test equipment and the like on the nonmagnetic test platform, dragging the semi-submersible carrying and maintaining platform into water, controlling a valve in a floating pile to open for water injection, enabling the platform to submerge to the required depth, starting a winch, separating the test platform, and starting a test. After the test is finished, starting the test platform aerating device, simultaneously fixing the test platform aerating device on a slideway of a deck of the semi-submersible type carrying and maintaining platform by using a winch for traction, starting a floating pile electric pump for draining water and floating upwards, closing a valve after the water is drained, adjusting the draft of the semi-submersible type carrying and maintaining platform after the platform rises to the water surface, longitudinally drawing the test platform to a required position, and finishing the test.

The technical requirements of the semi-submersible type carrying and maintaining platform are as follows: size: the total length is 50 meters, the width is 6 meters, the weight is less than or equal to 50t, the bearing capacity is more than or equal to 40t, the marine stainless steel is suitable for 4-5-level sea conditions, and the maximum submergence depth is 500 meters. Wherein, 4 pieces of floating and diving pile are cylindrical hollow structure, single diameter is 2 meters, height is 1.5 meters, built-in charge pump and high-pressure solenoid valve, control water injection and drainage, with cable connection control.

A moon pool of 5m x 3 m is cut in the middle of the deck for operation. The winches are arranged on two sides of the long end of the deck, and the winches are required to be installed at the side positions, so that the test platform is prevented from being dragged. The winch is respectively wound with the enlightening nima rope of 150 meters and the diameter is 25 mm. The deck both sides installing support, the support is whole trapezoidal, and length 42 meters is high 2 meters, and the centre comprises the stainless steel pipe equilateral triangle of 41 length of side 2 meters, keeps stable in structure, and the protection test platform avoids external force to hurt.
