Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to an offshore wind power expansion platform with an anti-fall structure. Background Art

[0002] The offshore wind power hoisting platform, also known as the installation platform or wind power installation ship, is a ship or floating platform specially designed for the construction and maintenance of offshore wind farms. This type of platform is equipped with the necessary equipment and facilities to transport the various components of the wind turbine to the designated location, and to carry out hoisting and installation. Due to construction needs, the hoisting platform often adds an expansion platform. The outer periphery of the newly added expansion platform is fixed with guardrails. If the guardrails on the hoisting platform are improperly designed or inappropriately located, there is a possibility of affecting the construction. At the same time, the height and density of the guardrails may also affect the operator's field of vision, resulting in an inability to clearly see the working area. The absence of guardrails will affect the safety of the expansion platform. Therefore, there is an urgent need for an expansion platform that does not affect construction operations and can ensure safety. Summary of the invention

[0003] The present invention is intended to provide an offshore wind power expansion platform with an anti-fall structure to solve the problem that the guardrails of the current expansion platform may affect the construction.

[0005] The anti-falling device includes two transverse rods and two longitudinal rods, which are fixedly connected to form a rectangular frame. A safety net is arranged inside the rectangular frame, and the edges of the safety net are fixedly connected to the transverse rods and the longitudinal rods; the bottom ends of the two longitudinal rods are fixedly connected with a connecting plate, which is fixedly connected to the upper deck.

[0006] Furthermore, a plurality of slow-descent mechanisms are arranged at intervals on the lower surfaces of the transverse rod and the longitudinal rod, and the slow-descent mechanism includes a vertical sealing cylinder with an open end facing downward, a piston connected to a piston inside the sealing cylinder, a pull rod fixedly connected to the piston, and a bottom end of the pull rod vertically passes through the opening downward and is located outside the sealing cylinder, and a plurality of pull rods of the slow-descent structure are fixedly connected to the edge of the safety net.

[0007] Furthermore, the open end of each sealing cylinder is fixedly connected to a limiting plate, and a avoidance hole for the pull rod to pass through is provided at the center of the limiting plate.

[0008] Furthermore, an air intake pipe is fixedly connected to the top of the side wall of each sealing cylinder, the air intake pipe is communicated with the interior of the sealing cylinder, and a regulating valve for adjusting the air intake amount is provided on the air intake pipe.

[0009] Furthermore, the first support frame includes a plurality of columns and a plurality of diagonal braces, the plurality of columns are vertically fixed on the lower deck at intervals, the top of the columns are fixedly connected to the lower surface of the upper deck, one end of the diagonal brace is fixedly connected to the top of the column, and the other end of the diagonal brace is fixedly connected to the bottom end of an adjacent column, and the plurality of diagonal braces are arranged in a zigzag shape.

[0010] Furthermore, the lower surface of the lower deck is fixedly connected with a second support frame, the second support frame includes a plurality of long diagonal braces, the bottom ends of the long diagonal braces are fixedly connected with bottom reinforcing plates, the bottom reinforcing plates are fixedly connected to the ship, the top ends of the long diagonal braces are fixedly connected to the lower surface of the lower deck, each of the long diagonal braces is vertically fixedly connected with a plurality of vertical braces, the top ends of the vertical braces are fixedly connected to the lower surface of the lower deck.

[0012] Beneficial effects of the present invention:

[0013] 1. This solution sets anti-falling parts on the side wall at the edge of the upper deck, cancels the setting of guardrails, avoids the impact of guardrails on construction, and at the same time, the setting of anti-falling parts avoids the risk of falling of construction workers.

[0014] 2. In this solution, when preventing a fall, the anti-fall device absorbs the impact force through the cooperation of the sealing tube and the pull rod, slows down the descent, reduces the reaction force on the falling person, and thus reduces the possibility of injury due to the fall.

[0015] 3. When preventing a person from falling, the anti-fall device in this scheme, compared with the existing method of connecting the edge of the safety net with a spring and using the elastic force of the spring to reduce the impact, will not move up and down multiple times after the safety net catches the falling person. This avoids the situation where the falling person is bounced up and out of the safety net due to the elastic force of the spring when falling, and is therefore safer.

[0016] 4. The anti-fall device in this scheme is used on the offshore wind power expansion platform through the cooperation of the sealing tube and the piston, and has better durability. However, when the spring is used to reduce the shock of the safety net, the humidity at sea is high, and the spring is very easy to rust, which affects its performance and cannot effectively ensure the long-term normal use of the anti-fall device.

[0024] The embodiment is basically as shown in the attached Figure 1 ~Attached Figure 5 As shown:

[0025] An offshore wind power expansion platform with an anti-fall structure includes an upper deck 1, a lower deck 5 and a plurality of anti-fall parts 10. The lower deck 5 is fixedly installed on the ship. A guardrail 4 is fixedly installed at the edge of the lower deck 5. A first support frame is fixedly connected to the lower deck 5. The first support frame includes a plurality of columns 3 and a plurality of diagonal braces 2. The plurality of columns 3 are vertically fixed on the lower deck 5 at intervals. The top of the column 3 is fixedly connected to the lower surface of the upper deck 1, one end of the diagonal brace 2 is fixedly connected to the top of the column 3, and the other end of the diagonal brace 2 is fixedly connected to the bottom end of the adjacent column 3 and arranged in a zigzag shape. The upper deck 1 is located directly above the lower deck 5. The lower surface of the lower deck 5 is fixedly connected with a second support frame, which includes a plurality of long diagonal braces 9 and a plurality of inner diagonal braces 7. The bottom ends of the long diagonal braces 9 are fixedly connected with bottom reinforcing plates 8, which are fixedly connected to the ship. The top ends of the long diagonal braces 9 are fixedly connected to the lower surface of the lower deck 5. Each long diagonal brace 9 is vertically fixedly connected with a plurality of vertical braces 6, and the top ends of the vertical braces 6 are fixedly connected to the lower surface of the lower deck 5. A plurality of anti-falling parts 10 are fixedly connected to the side wall at the edge of the upper deck 1 in a transverse state, and the anti-falling parts 10 are closely adjacent to each other.

[0026] The anti-falling device 10 includes two transverse rods 101 and two longitudinal rods 102. The two transverse rods 101 and the two longitudinal rods 102 are fixedly connected to form a rectangular frame, and a safety net 103 is arranged inside the rectangular frame. The bottom ends of the two longitudinal rods 102 are fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the upper deck 1.

[0027] The lower surfaces of the transverse rod 101 and the longitudinal rod 102 are provided with a plurality of slow-down mechanisms at intervals. The slow-down mechanisms include a vertical sealing cylinder 104, the open end of the sealing cylinder 104 faces downward, and the open end of each sealing cylinder 104 is fixedly connected to a limit plate 109, and a avoidance hole is provided at the center of the limit plate 109. The piston 107 in the sealing cylinder 104 is connected to a piston 107, and a pull rod 108 is fixedly connected to the piston 107. The bottom end of the pull rod 108 vertically passes through the avoidance hole downward and is located outside the sealing cylinder 104. The pull rods 108 of the slow-down structures are fixedly connected to the edge of the safety net 103. The top of the side wall of each sealing cylinder 104 is fixedly connected to an air intake pipe 105, which is in communication with the interior of the sealing cylinder 104, and a regulating valve 106 for adjusting the intake amount is provided on the air intake pipe 105.

[0028] The specific implementation process is as follows:

[0029] When in use, when construction workers are on the lower deck 5 for construction operations, the guardrail 4 is used for protection to avoid the risk of construction workers falling from the lower deck 5. When construction is performed on the upper deck 1, there is no guardrail 4 at the edge of the upper deck 1, so it will not be blocked by the guardrail 4. For some construction that will be affected by the guardrail 4, construction operations can be performed conveniently and quickly. When construction workers are performing construction on the upper deck 1, if they accidentally step out of the range of the upper deck 1, because there are multiple anti-falling parts 10 fixedly connected to the edge of the upper deck 1, and the anti-falling parts 10 are closely adjacent to each other, when the construction workers step out of the range of the upper deck 1, they will fall into the safety net. 103, since the edge of the safety net 103 is fixedly connected to the pull rods 108 of several slow-down mechanisms, after the safety net 103 catches the construction personnel, the safety net 103 falls and pulls the multiple pull rods 108 to move downward synchronously. When the pull rods 108 move downward, they pull the piston 107 from the inner top of the sealing cylinder 104 to move downward. When the piston 107 moves downward, the air pressure above the inside of the sealing cylinder 104 becomes lower and lower, and the air pressure difference between the outside of the sealing cylinder 104 and the inside of the sealing cylinder 104 gradually increases, and the pressure difference will push the piston 107 to its original position. At the same time, when the piston 107 moves downward, the gas molecules in the air have viscosity, so a certain resistance will be formed when the piston 107 moves downward, so that the downward movement speed of the pull rod 108 will gradually slow down, forming a buffering effect. At the same time, the amount of air intake in the air intake pipe 105 and the sealing cylinder 104 can be adjusted by the regulating valve 106 to adjust the slow-down speed when the pull rod 108 moves downward.
