[0012] Preferably, one end of the bottom of the longitudinal rope is rotatably connected to an elastic rod, and one end of the top of the elastic rod is sleeved with a metal sleeve.

[0013] Preferably, arc-shaped drainage plates are evenly installed on the outside of the hanger, rope loops are provided at both ends of the hanger, and the hooks are installed at the bottom of the rope loops, which improves the safety and stability of equipment use and reduces the cost of replacing parts when the equipment is worn.

[0014] The present invention provides a hoisting device for installing offshore wind power equipment, which has the following beneficial effects: 1. The hoisting equipment used for installation of offshore wind power equipment, the heat generated by the electric heating rod inside the truncated table causes the temperature of the truncated table to rise, the volume of the air inside the inflatable bag expands after being heated, and pushes the push plate to move toward the outside of the control slot, and during the movement of the push plate, the baffle is pulled toward the inside of the control slot until the baffle no longer blocks the elastic plate, and the elastic plate extends outward to the outside of the storage slot due to its own elasticity, at this time the elastic plate is unfolded to the outside of the truncated table and contacts the outer tube of the wind power equipment fixed on the sea surface, and the bottom end of the elastic plate is supported by the outer tube of the wind power equipment fixed on the sea surface and then pushes the hanger The wind turbine equipment moving on the hanger is laterally offset until the wind turbine equipment hoisted on the hanger is docked with the outer tube of the wind turbine equipment fixed on the sea surface. At this time, the bottom of the elastic plates at different positions on the outside of the truncated table are supported by the outer tube of the wind turbine equipment fixed on the sea surface and push the wind turbine equipment on the hanger with the same force, which is in a balanced state. The elastic plates no longer push the wind turbine equipment on the hanger to move, so that the equipment has the ability of automatic calibration and can automatically assist in calibration during the hoisting of the wind turbine equipment, avoiding the large amount of manpower required for manual pushing when the wind turbine equipment is docked, and reducing the difficulty of hoisting and installing the wind turbine equipment.

[0015] 2. The hoisting equipment used for installing offshore wind power equipment continuously blows toward the truncated table through the wind on the sea surface. The wind enters the longitudinal groove through the heat dissipation holes and takes away the heat generated by the electric heating rod. At this time, the temperature of the truncated table is not high due to the cooling of the wind on the sea surface. Then the hydraulic cylinder and the rotating table drive the support arm and the wind power equipment fixed below to move until the wind power equipment moves to the vicinity of the wind power equipment base and the outer tube that have been fixed on the sea surface. The truncated table moves to the inside of the wind power outer tube fixed on the sea surface. At this time, the wind on the sea surface is blocked by the outer tube of the wind power equipment and cannot move to the truncated table to cool down the truncated table. The heat generated by the electric heating rod inside the truncated table causes the temperature of the truncated table to rise, which is full of When the air inside the airbag is heated, its volume expands and pushes the push plate to move toward the outside of the control slot. During the movement of the push plate, the baffle is pulled toward the inside of the control slot until the baffle no longer blocks the elastic plate. The elastic plate extends outward to the outside of the storage slot due to its own elasticity. At this time, the elastic plate unfolds to the outside of the cone and contacts the outer tube of the wind turbine equipment fixed on the sea surface. After the bottom end of the elastic plate is supported by the outer tube of the wind turbine equipment fixed on the sea surface, it pushes the moving wind turbine equipment on the hanger to shift laterally. The wind at sea and the heat changes of the equipment are used to automatically detect the approach of the equipment and perform calibration. There is no need for human observation of the equipment and manual control, which improves the intelligence of the equipment.

[0016] 3. The hoisting equipment used for installing offshore wind power equipment improves the adaptability of the equipment by adjusting the overall length of the outer tube and the extension rod, and can meet the needs of hoisting wind power equipment of different lengths.

[0017] 4. When the hoisting equipment for installing offshore wind power equipment enters the wind power equipment shell through the longitudinal rope, the light is blocked by the wind power equipment shell, resulting in dark light inside the outer tube, and the photosensitive element controls the power supply and the electric push rod to be energized. The photosensitive element uses a photosensitive element inside a photosensitive lamp to control the circuit to be energized and illuminated when the light is dark. The electric push rod pushes the extension rod down, and the elastic rope is stretched and deformed. The elastic rod is blocked by the outside of the wind power equipment and then tilted and slides downward along the inner wall of the wind power equipment shell. The metal sleeve prevents the elastic rod from being worn when rubbing against the wind power equipment shell until the bottom end of the longitudinal rope extends downward to the wind power equipment. Below the equipment casing, the elastic rod is no longer blocked by the wind turbine equipment casing and rotates to the horizontal direction. At this time, the light enters the longitudinal rope through the light-transmitting hole, and then is reflected by the longitudinal rope and the reflective film inside the light-transmitting groove to enter the outer tube. After the brightness of the light inside the outer tube is enhanced, the power supply of the photosensitive element control power supply and the electric push rod are not energized, the electric push rod stops working, and the elastic rope pulls the extension rod up due to its own elastic force until the elastic rod is blocked by the wind turbine equipment casing and then blocks the longitudinal rope from continuing to rise, thereby improving the intelligence of the equipment and using light to automatically adjust the length of the equipment to meet the hoisting use of wind turbine equipment of different lengths.

[0018] 5. The hoisting equipment used for installing offshore wind power equipment uses a protective plate to prevent the inflatable bag from entering the longitudinal groove and contacting the electric heating rod to be burned when it expands, thereby improving the safety of equipment use. The arc-shaped guide plate guides the wind blowing from the sea surface to the hanger upward, reduces the influence of the sea breeze on the hanger, and improves the stability of the hoisting. The hook is connected to the hanger by a rope loop. During use, the rope loop and the hanger rub and wear. When the wear is serious, the rope loop is directly replaced, which reduces the cost of replacing parts when the equipment is worn. BRIEF DESCRIPTION OF THE DRAWINGS

The control groove 13 is connected to the longitudinal groove 17. A protective plate 19 is fixedly connected to the inner wall of the longitudinal groove 17 near the control groove 13. Heat dissipation holes 20 are evenly provided on the outer side of the truncated cone 10. The heat dissipation holes 20 are connected to the longitudinal groove 17. The protective plate 19 prevents the inflatable bag 15 from entering the longitudinal groove 17 and contacting the electric heating rod 18 to be burned when it expands, thereby improving the safety of the equipment.

[0023] A base 1 is installed on one side of the hanger 6, a rotating table 2 is installed on the top of the base 1, the top of the rotating table 2 is rotatably connected to the support arm 3, the top of the rotating table 2 is rotatably connected to the support arm 3 through a hydraulic cylinder 4, and one end of the top of the support arm 3 is fixedly connected to the hanger 6 through a transverse block 5.

[0024] Arc-shaped guide plates 34 are evenly installed on the outside of the hanger 6, and rope loops 35 are sleeved on both ends of the hanger 6. The hook 7 is installed at the bottom of the rope loop 35. The arc-shaped guide plates 34 guide the wind blowing from the sea surface to the hanger 6 upward, reduce the influence of the sea breeze on the hanger 6, and improve the stability of the lifting. The hook 7 is connected to the hanger 6 by the rope loop 35. During use, the rope loop 35 and the hanger 6 rub against each other and wear. When the wear is serious, the rope loop 35 is directly replaced, which reduces the cost of replacing parts when the equipment is worn.

[0025] When in use, the rotating platform 2 drives the support arm 3 to rotate to the top of the wind power equipment, and the hydraulic cylinder 4 controls the end of the support arm 3 to descend until the hook 7 descends to the wind power equipment, fixes the hook 7 to the wind power equipment, and the longitudinal rod 8 and the longitudinal rope 9 pass through the shell of the wind power equipment. Finally, the round table 10 extends to the bottom of the shell of the wind power equipment. The electric heating rod 18 is turned on to generate heat. The wind on the sea surface continues to blow towards the round table 10. The wind passes through the heat dissipation holes 20 and enters the longitudinal groove 17 to take away the heat generated by the electric heating rod 18. At this time, the temperature of the round table 10 is not high due to the cooling of the wind on the sea surface, and then the hydraulic cylinder 4 controls the end of the support arm 3 to descend until the hook 7 descends to the wind power equipment. The pressure cylinder 4 and the rotating table 2 drive the support arm 3 and the wind turbine equipment fixed below to move until the wind turbine equipment moves to the vicinity of the wind turbine equipment base and outer tube that have been fixed on the sea surface, and the round table 10 moves to the inside of the wind turbine outer tube that has been fixed on the sea surface. At this time, the wind on the sea surface is blocked by the outer tube of the wind turbine equipment and cannot move to the round table 10 to cool the round table 10. The heat generated by the electric heating rod 18 inside the round table 10 causes the temperature of the round table 10 to rise. The volume of the air inside the inflatable bag 15 expands after being heated, pushing the push plate 16 to move toward the outside of the control slot 13. During the movement of the push plate 16 The baffle 14 is pulled toward the inside of the control groove 13 until the baffle 14 no longer blocks the elastic plate 12. The elastic plate 12 extends outward to the outside of the storage groove 11 due to its own elasticity. At this time, the elastic plate 12 is unfolded to the outside of the truncated table 10 and contacts the outer tube of the wind turbine equipment fixed on the sea surface. The bottom end of the elastic plate 12 is supported by the outer tube of the wind turbine equipment fixed on the sea surface and then pushes the moving wind turbine equipment on the hanger 6 to shift laterally. The wind at sea and the heat change of the equipment are used to automatically detect the approach of the equipment and perform calibration. There is no need for human observation of the equipment and manual control, which improves the intelligence of the equipment. The energy level is adjusted until the wind turbine equipment hoisted on the hanger 6 is docked with the outer tube of the wind turbine equipment fixed on the sea surface. At this time, the bottom of the elastic plates 12 at different positions on the outside of the truncated table 10 is supported by the outer tube of the wind turbine equipment fixed on the sea surface, and the force pushing the wind turbine equipment on the hanger 6 is the same and in a balanced state. The elastic plates 12 no longer push the wind turbine equipment on the hanger 6 to move, so that the equipment has the ability of automatic calibration, and can automatically assist in calibration during the hoisting process of the wind turbine equipment, avoiding the large amount of manpower required for manual pushing when the wind turbine equipment is docked, and reducing the difficulty of hoisting and installing the wind turbine equipment. Example

[0026] See also Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the longitudinal rod 8 includes an outer tube 21, the top of the outer tube 21 is fixedly connected to the hanger 6, and an extension rod 22 is installed at the bottom of the outer tube 21. One end of the top of the extension rod 22 extends to the inside of the outer tube 21 and is slidably connected to the inner wall of the outer tube 21.

[0027] An electric push rod 23 is fixedly connected to the inner top of the outer tube 21 , one end of the top of the electric push rod 23 is fixedly connected to the extension rod 22 , and an elastic rope 24 is symmetrically installed on the inner top of the outer tube 21 , and the bottom of the elastic rope 24 is fixedly connected to the extension rod 22 .

[0028] The interior of the longitudinal rope 9 is hollow, and a light-transmitting groove 25 is symmetrically opened at the top of the extension rod 22 near the electric push rod 23. The light-transmitting groove 25 passes through the extension rod 22 and is connected to the longitudinal rope 9. A light-transmitting hole 26 is symmetrically opened at one end of the bottom of the longitudinal rope 9.

[0029] The inner walls of the longitudinal rope 9 and the light-transmitting groove 25 are both installed with a reflective film 27 , and the inner wall of the outer tube 21 is installed with a reflective mirror 28 .

[0030] A power source 29 and a photosensitive element 30 are fixedly connected to one side of the inner wall of the outer tube 21 . The power source 29 penetrates the outer tube 21 and extends to the outside of the outer tube 21 . The power source 29 , the photosensitive element 30 and the electric push rod 23 are electrically connected via a wire 31 .

[0031] One end of the bottom of the longitudinal rope 9 is rotatably connected to an elastic rod 32 , and one end of the top of the elastic rod 32 is sleeved with a metal sleeve 33 .

[0032] When in use, the longitudinal rod 8 and the longitudinal rope 9 pass through the hoisted wind turbine housing and move to the bottom of the wind turbine housing. When the longitudinal rope 9 enters the interior of the wind turbine housing, the light is blocked by the wind turbine housing, resulting in dark light inside the outer tube 21. The photosensitive element 30 controls the power supply 29 and the electric push rod 23 to be energized. The photosensitive element 30 uses a photosensitive component inside a photosensitive lamp to control the circuit to be energized and emit light when the light is dark. The electric push rod 23 pushes the extension rod 22 to descend, and the elastic rope 24 is stretched and deformed. The elastic rod 32 is blocked by the outside of the wind turbine and then tilted and slides downward along the inner wall of the wind turbine housing. The metal sleeve 33 prevents the elastic rod 32 from wearing out when rubbing against the wind turbine housing, until the bottom end of the longitudinal rope 9 extends downward to the bottom of the wind turbine housing, and the elastic rod 32 is no longer affected by the wind. After being blocked by the casing of the wind power equipment, it rotates to the horizontal direction. At this time, the light enters the interior of the longitudinal rope 9 through the light-transmitting hole 26, and then is reflected by the longitudinal rope 9 and the reflective film 27 inside the light-transmitting groove 25 to enter the interior of the outer tube 21. After the brightness of the light inside the outer tube 21 is enhanced, the photosensitive element 30 controls the power supply 29 and the electric push rod 23 to be de-energized, and the electric push rod 23 stops working. The elastic rope 24 pulls the extension rod 22 up due to its own elastic force until the elastic rod 32 is blocked by the casing of the wind power equipment and blocks the longitudinal rope 9 from continuing to rise. The equipment can be automatically controlled to adjust its length, which improves the adaptability of the equipment and can meet the hoisting needs of wind power equipment of different lengths, thereby preventing the round table 10 with a high temperature from entering a deeper position inside the outer tube of the wind power equipment fixed on the sea surface due to the excessive length of the equipment and causing burns and damage.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
