Description

Technical Field

[0001] The utility model relates to the technical field of marine rescue auxiliary equipment, in particular to a marine rescue device for people falling into water. Background Art

[0002] As my country is accelerating the development of the offshore wind power industry, during the installation and construction of offshore wind turbines, an offshore wind power platform ship lifts the platform to a specified height by inserting piles to complete the hoisting, and there are a large number of construction workers on the platform and wind turbines. At the same time, in order to obtain better wind energy resources, the site of an offshore wind farm is generally planned to be more than 10 nautical miles from the shore and more than 10 meters deep. With the research and development and investment of large-scale offshore wind turbines, the site of an offshore wind farm is gradually advancing to the deep sea. Therefore, during the construction of offshore wind power, once an emergency occurs on the platform where people fall into the water, due to the large air gap of the platform and the distance from the shore, it is impossible to provide timely and effective rescue for the people who fall into the water.

[0003] Some of the similar devices currently installed on rescue ships use a winch structure or a life-saving boom structure, which has poor stability in rescuing people who fall into the water in windy and rough weather. Some use a gantry lifting structure, which is large and complex, not conducive to the installation and use of small emergency tugboats, and increases the cost of use. The rescue methods for people who fall into the water on offshore wind power platforms include releasing life (assistance) boats, throwing life rafts, lifebuoys, and emergency tugboats using life poles to salvage, but the above methods have many defects such as untimely rescue, unstable rescue effects, and easy to cause secondary injuries. Therefore, it is imperative to design a personnel rescue device that is installed on a small tugboat with a simple structure and stable effects and put it into use. Utility Model Content

[0024] The flip support frame 7 is arranged on the ship's side of the fixed support frame 2, and includes a flip plate 701 and two second guardrails 702; wherein the flip plate 701 is horizontally arranged on the adjacent side of the support plate and is preferably flush with the top surface of the support plate; the two second guardrails 702 are vertically fixed on both sides of the flip plate 701 along the setting direction of the two first guardrails 6.

[0025] The flip bracket 8 includes an arc bracket 801 and two third guardrails 802; wherein the arc bracket 801 is a frame body with an L-shaped vertical cross section, which is specifically composed of two symmetrically arranged arc rods and a plurality of connecting rods fixed vertically between the two arc rods at intervals; the two third guardrails 802 are symmetrically fixed on the two arc rods of the arc bracket 801, so that the flip bracket 8 forms a bucket-shaped structure;

[0026] The flip bracket 8 is arranged in the flip support frame 7 in such a way that its side opening faces the fixed support frame 2 and the bottom opening faces the flip plate 701; two first connecting ears 9 are symmetrically arranged on the outer walls of the two arc-shaped rod ends located on the bottom side of the arc-shaped bracket 801, and two second connecting ears 10 are symmetrically arranged on the two third guardrails 802 located on the adjacent sides of the two first connecting ears 9; correspondingly, two third connecting ears are symmetrically arranged on the top surface of the end of the flip plate 701 close to the ship's side, and the two third connecting ears cooperate with the two second connecting ears 10, so that the flip plate 701 arranged in the flip support frame 7 in the stored state The bracket 8 is hingedly connected to the flip support frame 7 by a pin shaft passing through the third connecting ear and the second connecting ear 10 on each side; two fourth connecting ears 703 are symmetrically arranged on the bottom surface of the flip plate 701 at one end close to the ship's side, and the two fourth connecting ears 703 cooperate with the two first connecting ears 9; in the use state, the flip bracket 8 is flipped 90° outward relative to the flip support frame 7, so that the two fourth connecting ears 703 are positioned opposite to the two first connecting ears 9, and the flip support frame 7 and the flip bracket 8 are fixed in the open state by connecting and connecting with the pin shaft passing through the fourth connecting ear 703 on each side and the first connecting ear 9.

[0027] The turning mechanism includes two turning rods 11, a turning cylinder 12, a turning cylinder base 13, a turning cylinder top seat 15 and two turning rod bases 14; wherein,

The specific setting of the total length is set according to the tugboat model to ensure that when the flip support frame 7 and the flip bracket 8 are flipped to the outside of the hull, the bottom of the flip bracket 8 can penetrate into the underwater depth of 1m to ensure that the person who falls into the water can move into the bucket-shaped flip bracket 8.

[0032] The hydraulic pump 4 and the booster oil tank 5 are arranged on the main deck 1 near the up and down escalator 3. The booster oil tank 5 is connected to the oil chamber of the flip cylinder 12 through the hydraulic pump 4 and forms a communication to drive the extension or retraction of the movable push rod of the flip cylinder 12.

[0033] The specific use method of the marine rescue device for people falling into water is as follows:

[0034] S1. During offshore wind power construction, when a person falls into the water, the emergency guard tugboat equipped with the rescue device immediately goes to the place where the person falls into the water, and the rescue personnel climb onto the fixed support frame through the up-down escalator 3 to flip open the flip bracket 8, so that the flip bracket 8 and the flip support frame 7 are fixed in the open state; then, the hydraulic pump 4 is started, and the movable push rod of the flip cylinder 12 is gradually extended, so that the flip support frame 7 and the flip bracket 8 are gradually flipped outward by about 90°, and then lowered to the outside of the hull and probed into the water, and the rescue personnel use the lifesaving telescopic rod to assist the person who falls into the water to move into the flip bracket 8;

[0035] S2, after the person who falls into the water has firmly grasped the water, the movable push rod of the overturning cylinder 12 is gradually retracted by the hydraulic pump 4, so that the overturning support frame 7 and the overturning bracket 8 are gradually overturned back toward the main deck side and return to the initial state; at this time, the person who falls into the water holding the overturning bracket 8 is salvaged back to the side of the emergency guard tugboat, and the rescuers safely transfer the person who falls into the water to the main deck 1 through the up and down escalators 3;

[0036] S3. After the rescue of the drowning person is completed, the hydraulic pump 4 is turned off and other relevant rescue facilities are returned to their positions.

[0037] In summary, the offshore rescue device for people falling into the water can make full use of the emergency guard tugboat's own diesel generator to provide power. When people are found falling into the water during offshore construction operations, the hydraulic cylinder is extended and retracted to drive the lifting and lowering of the flip platform, which can withstand the impact of waves and other moving loads under severe sea conditions and achieve stable rescue of people who fall into the water.
