Those ordinarily skilled in the art may understand specific meanings of the above terms in the utility model depending on specific conditions.

[0020] A first embodiment

[0021] As shown in FIG. 1, the utility model provides an embodiment. An escape device for an offshore platform includes a platform body 1, a lifeboat 2, a support track 3 and two fixed mechanisms 4, wherein the support track 3 includes a horizontal track 31 and a mild-slope track 32, the horizontal track 31 is hinged with the platform body 1 on one end and is rotatable about a hinge shaft on the other end thereof; the mild-slope track 32 is fixedly connected with the fixed mechanisms 4 on a side surface, and the horizontal track 31 is in contact with an upper end of the mild-slope track 32 when rotating to the maximum angle with a horizontal line; the two fixed mechanisms 4 are symmetrically arranged on both sides of the support track 3, and vertically fixed to a side surface of the platform body 1; and the lifeboat 2 is placed above the horizontal track 31.

[0022] As shown in FIG. 2, the fixed mechanisms 4 are fixed plates 41 with guide grooves 42 in side surfaces. The fixed plates 41 are arranged vertically. One sides, which are provided with the guide grooves 42, of the fixed plates 41 face the support track 3, and the other sides thereof are fixedly connected with the platform body 1.

[0023] Guide wheels 21 matching with the guide grooves 42 of the fixed plates 41 are disposed on two side surfaces of the lifeboat 2. One fixed plate 41 is fixedly connected with a side surface of the platform body 1 to make the connection area larger and more stable. An upper surface of the fixed plate 41 and an upper surface of the platform body 1 are on the same horizontal plane, and the two fixed plates 41 are arranged in parallel. The support track 3 is disposed between the two fixed plates 41, there are two parallel slide rails of the support track 3, and the two fixed plates 41 are fixedly connected with the two slide rails by the lateral support rods. A stabilizing plate 43 is disposed on side surfaces of the twofixed plates 41, and fixedly connected with the two fixed plates 41 simultaneously. The guide grooves 42 are disposed in opposite surfaces of the two fixed plates 41. The guide wheels 21 and the guide grooves 42 are disposed on side surfaces of the lifeboat 2, and the guide wheels 21 may slide or roll.

[0024] As shown in FIG. 3, two limit plates 22 are disposed on a bottom surface of the lifeboat 2, and symmetrically arranged along a center line of the lifeboat. The two limit plates 22 are just clamped between the two slide rails of the support track 3 to restrict a left and right movement of the lifeboat 2 on the support track 3.

[0025] A cable 33 is disposed on a rotatable end of the horizontal track 31, the other end of the cable 33 is wound on a roller 34, the roller 34 is fixed on the platform body 1, and the roller 34 is driven by a motor.

[0026] The mild-slope track 32 includes a second slide rail 321 and a plurality of second lateral support rods 322. The second lateral support rods 322 are fixed to the outside of the second slide rail 321 on one ends and fixed to one sides, which are away from the platform body 1, of the fixed plate 41 on the other ends thereof. A support connector is disposed at a lower end of the horizontal track 31. The horizontal track 31 rotates and is connected with an upper end of the second slide rail 321. The support connector is clamped onto the second lateral support rods 322 to make the support track 3 firm and stable.

[0027] A telescopic airbag is disposed on a bottom of a front end of the lifeboat 2. When the lifeboat 2 reaches the sea surface, the impact of the seawater on the lifeboat 2 is reduced. A rear end of the lifeboat 2 is connected with the horizontal track 31 by a fixed structure, such as a chain, a hook, and a buckle.

[0028] When an accident occurs, a worker enters the lifeboat 2, turns on the motor, and drives the roller 34 to rotate. The cable 33 is enabled to put one end of the horizontal track 31 down, the horizontal track 31 rotates around a hinged end, and one end of the horizontal track 31 rotates to a position connected with the upper end of the second slide rail 321. The support connector of the horizontal track 31 is clamped onto the second lateral support rods 322. The horizontal track 31 and the mild-slope track 32 form a smoothly-connected track. The fixed structure at a rear end of the lifeboat 2 is opened, so that the lifeboat 2 slides down the support track 3. The limit plates 22 restrict the left and right movement of the lifeboat 2, and the guide grooves 42 and the guide wheels 21 limit a slide trajectory of the lifeboat 2, which prevents the lifeboat 2 from overturning in a sliding process. If there are too many workers, the horizontal track 31 may be lengthened, the number of the lifeboats 2 may be increased, and the time to open the fixed structure at the rear end of the lifeboat 2 may be changed to allow the workers to escape, so as to avoid accidents due to collisions of the lifeboats 2.

[0029] A second embodiment

[0030] As shown in FIG. 4, on the basis of the above technical solution, the support track 3 employs a U-shaped slide rail with an upwards opening. Limit plates 22 at a bottom of the lifeboat 2 are replaced with wheels, so that the traveling speed of the lifeboat 2 may be increased, and the escape time may be saved.

[0031] It should be understood that although the description is explained according to the embodiments, not every embodiment only contains an independent technical solution, and such an explaining manner of the description is only for the sake of clarity. Those skilled in the art should take the Description as a whole. The technical solutions in the embodiments may be appropriately combined to form other embodiments understandable by those skilled in the art.
