Description

Technical Field

[0001] The invention relates to the field of offshore operations, in particular to a supporting structure for offshore high-altitude operations. Background Art

[0002] High-altitude operations at sea generally involve erecting brackets to install floating lamps. The brackets can be used for offshore photovoltaic construction, etc. Offshore photovoltaics use large areas of water at sea to deploy photovoltaic panels, which absorb solar energy and convert it into electrical energy. Compared with photovoltaic power generation systems on land, offshore photovoltaics have some unique advantages. Offshore photovoltaics is a potential renewable energy power generation method. It can not only effectively utilize marine resources and improve energy output efficiency, but also reduce energy transmission losses. With the continuous advancement of technology and the reduction of costs, offshore photovoltaics will play a more important role in the future and contribute to the development of sustainable energy.

[0003] A mechanical arm is provided on the existing support floating vessel to support the support plate upwards. The personnel go up on the support plate and are sent to the installation work site above the sea for work through the transfer and movement of the mechanical arm. However, the existing support plate only has guardrails to prevent personnel from falling from the support plate, and the height of conventional guardrails generally does not exceed the waist of a person. Because the guardrail is too high, it affects the personnel's arms to extend the guardrail to work. When the personnel are working, they sometimes lean forward, which can easily cause the employees to flip over the guardrail and fall down. For this reason, a support structure for high-altitude work at sea is needed to improve the protection effect. Summary of the invention

The four corner side walls of the top end of the floating boat body are connected to four positioning rods, the top end of the positioning rod is connected to a pulley, and an iron chain is movably placed on the pulley. The top side wall of the floating boat body is connected to four reduction motors, the output end of the reduction motor is connected to the winding roller, the side wall of the winding roller is wound and connected with the iron chain, the end of the iron chain is connected to the anchor hook, and the power control box is electrically connected to the reduction motor.

[0007] Preferably, the power control box and the bottom end of the robotic arm are both located on the inner side of the fence, and the fixing mechanism is located on the outer side of the fence.

[0008] Preferably, the supporting mechanism includes a supporting plate, a guardrail, a second sealing door, a first screw hole and a placement slot; the end of the robotic arm is connected to the supporting plate, the top of the supporting plate is connected to the guardrail, the side wall of the guardrail is rotatably connected to the second sealing door, the outer side wall of the guardrail is provided with three placement slots, and the side wall of the placement slot is provided with a first screw hole.

[0009] Preferably, the guardrail is in a U-shape.

[0010] Preferably, the adjustment mechanism includes a slide groove, a round rod, a bottom plate, a top block, a support rod, a first plugging hole and a first slide hole, the side walls on both sides of the placement groove are provided with slide grooves, the side walls of the slide groove are connected with round rods, the side walls on both sides of the top end of the bottom plate are provided with first slide holes, the side walls of the first slide holes are slidably connected to the round rods, the side walls of the bottom plate are slidably connected to the slide grooves, the top end of the bottom plate is connected to two symmetrically distributed top blocks, the side walls of the top blocks are connected with two support rods, and the side walls of the support rods are provided with a plurality of first plugging holes distributed in an array.

[0011] Preferably, the height of the bottom plate is smaller than the height of the placement groove.

[0012] Preferably, the limiting mechanism includes a baffle, a second screw hole, a second sliding hole, a second insertion hole, a positioning screw and a limiting screw. The side wall of the baffle is provided with two symmetrically distributed second sliding holes, the side wall of the second sliding hole is slidably connected to the support rod, the top of the baffle is provided with a second screw hole, the side wall of the second screw hole is threadedly connected to the positioning screw, and the side wall of the first screw hole is threadedly connected to the limiting screw.

[0013] Preferably, a rubber pad is sleeved on the side wall of the baffle, and the shape of the baffle is T-shaped.

[0014] The beneficial effects of the present invention are:

[0015] 1) After the floating vessel body is driven to the working sea surface, the reduction motor is started to rotate the winding roller, thereby placing the iron chain downward, so that the hook anchor 604 can be hooked on another driving boat to pull the floating vessel body 1, ensuring the stability of the floating vessel body, opening the second sealing door, and the personnel boarding the support plate and closing the second sealing door, and starting the mechanical arm, which moves the supporting mechanism to the working position on the sea surface, thereby facilitating the operation of the employees.

[0016] 2) After the personnel board the support plate, the guardrail and the second sealing door can be used to prevent the personnel from falling down. Then, when the employees are working, the side wall of the guardrail is directed toward the offshore operation site through the mechanical arm. At this time, the limiting mechanism on the placement slot toward the operation site is pulled, and the limiting mechanism pulls the support rod to move upward. The support rod pulls the bottom plate upward through the top block. The first sliding hole is slidably connected along the sliding groove and the round rod, and the side wall of the bottom plate is slidably connected to the sliding groove, to ensure the stable movement of the bottom plate, thereby ensuring the normal movement effect of the limiting mechanism.

[0017] 3) By using the sliding connection between the support rod and the second sliding hole, the baffle can be pushed to slide left and right along the support rod to facilitate the adjustment of the left and right position of the baffle. By using the threaded connection between the second screw hole and the positioning screw, the positioning screw can keep the synchronous movement with the baffle. Then, the positioning screw is aligned with the first plug hole, and the positioning screw is screwed downward to insert the positioning screw into the first plug hole to limit the left and right movement of the baffle. The plurality of first plug holes and first screw holes are used to increase the adjustable position of the baffle in the left and right directions. Then, the baffle is pulled upward to extend the placement slot upward, thereby extending the height of the guardrail. In addition, the width of the baffle is smaller than that of a person with a normal body shape. The guardrail blocks the front of the person's legs, and the baffle blocks the front of the person's chest to prevent the person from leaning forward and turning over the guardrail. The person's hands can extend from both sides of the baffle to the outside of the guardrail, and the baffle can also prevent the baffle from hindering normal two-handed operation. The baffle drives the positioning screw and the second hole to move. Because the support rod and the second sliding hole are slidably connected, the support rod is also driven to move upward, and then the second hole is aligned with the first screw hole, and the limiting screw is rotated to insert the limiting screw into the second hole, so that the baffle is fixed on the guardrail. The multiple second holes are used to increase the fixed state of the baffle to better adapt to the chest height of the person. BRIEF DESCRIPTION OF THE DRAWINGS
