Description

Technical Field

[0001] This utility model relates to the field of wind turbine nacelle technology, and in particular to an opening and closing mechanism and an offshore wind turbine nacelle. Background Technology

[0002] With the increasing global demand for clean energy, offshore wind power has received widespread attention as a sustainable energy solution. As one of the core components of a wind turbine, the nacelle of an offshore wind turbine houses many critical devices, such as generators, gearboxes, and brakes. The normal operation of these devices is crucial for the stable power generation of the entire wind turbine.

[0003] In the actual operation of offshore wind turbines, poor heat dissipation can lead to excessively high temperatures inside the nacelle, affecting the performance and lifespan of the equipment, and may even cause malfunctions and shutdowns. Furthermore, offshore wind turbines are usually installed on offshore platforms or wind turbine ships far from land, and the opening and closing of the nacelle is easily affected by factors such as waves and sea winds. In calm sea conditions, the nacelle can be opened to a large extent to facilitate ventilation, heat dissipation, and personnel access. However, in situations with large waves or high wind speeds, the nacelle needs to reduce the opening and closing range, or even be completely closed, to prevent seawater and salt spray from entering the nacelle and damaging the equipment.

[0004] Based on the above problems, we propose an opening and closing mechanism and an offshore wind turbine nacelle. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is: how to assist in heat dissipation inside the engine room while the engine room is being opened and closed, and how to adjust the size of the engine room opening and closing according to different sea and wind conditions.

[0006] The above-mentioned technical problem is solved by the following technical solution: a ventilation component, including a driving component, a filter component disposed outside the driving component, and a movable component disposed on the outer wall of the driving component; the driving component passes through the filter component and is movably connected to the movable component.

[0007] In a preferred embodiment of the opening and closing mechanism of this utility model: the driving component includes a motor, and the output end of the motor is provided with a rotating shaft.

[0008] In a preferred embodiment of the opening and closing mechanism of this utility model: a connecting rod is provided on the outer wall of the rotating shaft, and a moving rod is provided on the outer wall of the connecting rod.

[0009] In a preferred embodiment of the opening and closing mechanism of this utility model: the filter element includes a filter screen disposed outside the moving rod, and the outer wall of the filter screen has a groove.

[0010] In a preferred embodiment of the opening and closing mechanism of this utility model: the moving rod is in movable cooperation with the slot.

[0011] In a preferred embodiment of the opening and closing mechanism of this utility model: the movable component includes a door panel disposed outside the moving rod, and a fixing block is provided on the outer wall of the door panel.

[0012] In a preferred embodiment of the opening and closing mechanism of this utility model: the outer wall of the moving rod is provided with a column, and the column is movably engaged with the fixed block.

[0013] The beneficial effects of this utility model are as follows: by setting up a ventilation component, the door panel can be opened, and under the action of pressure difference, air enters from the rear air intake of the cabin and flows out from the side wing, thus forcibly dissipating heat from various components inside the cabin.

[0014] This utility model also proposes an offshore wind turbine nacelle, which includes a main component including a nacelle, a hub disposed on the outer wall of the nacelle, a ventilator disposed on the outer wall of the nacelle, and a limit switch disposed on the outer wall of the nacelle.

[0015] In a preferred embodiment of the offshore wind turbine nacelle of this utility model: the ventilator includes an opening in the outer wall of the nacelle, and multiple baffles are provided inside the opening.

[0016] In a preferred embodiment of the offshore wind turbine nacelle of this utility model: an air inlet is provided between the plurality of baffles.

[0017] Another beneficial effect of this utility model is that by setting a limit switch, the size of the cabin opening and closing can be adjusted accordingly under different sea and wind conditions. In severe sea and wind conditions, the limit switch can quickly close the cabin door to prevent seawater and strong winds from entering the cabin and protect the safety of equipment and personnel.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Reference Figures 1-3 This embodiment provides an opening and closing mechanism, including a ventilation assembly 1, including a drive member 11, a filter member 12 disposed outside the drive member 11, and a movable member 13 disposed on the outer wall of the drive member 11; the drive member 11 passes through the filter member 12 and is movably connected to the movable member 13.

[0025] The ventilation components 1 are preferably configured as two sets, symmetrically arranged on both sides of the cabin; the drive component 11 is fixedly installed on the inner wall of the cabin 21; the filter component 12 is connected to the cabin 21 and can filter impurities in the air; the movable component 13 can perform opening and closing actions under the drive component 11 to realize the opening and closing function of the cabin door.

[0026] As an optional embodiment, the drive unit 11 includes a motor 111, and the output end of the motor 111 is provided with a rotating shaft 112.

[0027] The motor 111 is fixedly installed on the inner wall of the cabin 21. The motor 111 is preferably a servo motor. When the motor 111 is started, it can drive the rotating shaft 112 to rotate.

[0028] As an optional embodiment, the outer wall of the rotating shaft 112 is provided with a connecting rod 113, and the outer wall of the connecting rod 113 is provided with a moving rod 114.

[0029] The connecting rod 113 is fixedly connected to the rotating shaft 112. The connecting rod 113 and the moving rod 114 are integrally connected. When the rotating shaft 112 rotates, the connecting rod 113 can rotate, thereby driving the moving rod 114 to rotate.

[0030] As an optional embodiment, the filter element 12 includes a filter screen 121 disposed outside the moving rod 114, and the outer wall of the filter screen 121 has a groove 122.

[0031] The filter screen 121 is set at the openings on both sides of the chamber 21 to prevent impurities from affecting the operation of the equipment inside the chamber 21. The slot 122 is set to facilitate the passage of the moving rod 114, thereby driving the opening and closing of the door panel 131. The setting of the slot 122 does not affect the overall filtration effect of the filter screen 121.

[0032] As an optional embodiment, the movable rod 114 is movably engaged with the slot 122.

[0033] The opening of the slot 122 is larger than the length of the movement path of the moving rod 114 to prevent the slot 122 from blocking the movement of the moving rod 114. When the motor 111 rotates, the moving rod 114 can move within the slot 122.

[0034] As an optional embodiment, the movable component 13 includes a door panel 131 disposed outside the movable rod 114, and a fixing block 132 is provided on the outer wall of the door panel 131.

[0035] One end of the door panel 131 is rotatably connected to the outer wall of the cabin 21, and the fixing block 132 is located on the side of the door panel 131 near the cabin 21. The fixing block 132 and the door panel 131 are an integral connection structure.

[0036] As an optional embodiment, the outer wall of the movable rod 114 is provided with a column 115, which is movably engaged with the fixed block 132.

[0037] The column 115 is fixedly installed on the outer wall of the moving rod 114. The outer wall of the fixing block 132 has a movable hole that matches the column 115. The column 115 and the fixing block 132 are rotatably engaged. When the moving rod 114 rotates, the door panel 131 can be opened or closed through the rotatable engagement of the column 115 and the fixing block 132. The opening angle of the door panels 131 on both sides of the cabin can be controlled at about 15°, which will not change the aerodynamic characteristics.

[0038] In use, the drive motor 111 rotates the shaft 112, causing the connecting rod 113 to rotate. Since the connecting rod 113 and the moving rod 114 are integrated, the moving rod 114 moves within the slot 122. Since the column 115 and the moving rod 114 are fixedly connected, the column 115 and the fixed block 132 rotate to open the door panel 131. At this time, air enters through the air inlet 233. After circulating inside the cabin 21, the air flows out through the opening of the door panel 131, cooling the equipment inside the cabin 21 and thus improving the operating efficiency of the offshore wind turbine.

[0039] Reference Figures 1-3 This embodiment provides an offshore wind turbine nacelle, including a main component 2, including a nacelle 21, a hub 22 disposed on the outer wall of the nacelle 21, a ventilator 23 disposed on the outer wall of the nacelle 21, and a limit switch 24 disposed on the outer wall of the nacelle 21.

[0040] The ventilation component 23 is located at the rear of the cabin 21, allowing air to enter the cabin 21. The limit switch 24 is connected to the outer wall of the cabin 21 by bolts. The limit switch 24 is located at the opening of the door panel 131 and is connected to the fan main control via the motor signal, enabling remote operation and control of the opening angle of the door panel 131.

[0041] As an optional embodiment, the vent 23 includes an opening 231 formed in the outer wall of the cabin 21, and a plurality of baffles 232 are provided inside the opening 231.

[0042] The opening 231 is located at the rear of the cabin 21. Air enters from the rear, passes through the equipment inside the cabin, and then flows out from the side wing, which helps to improve heat dissipation efficiency. Multiple baffles 232 are set at a certain interval and in a certain arrangement. The arrangement of multiple baffles 232 can guide and divert the incoming air, so that the air can enter the cabin evenly and avoid excessive local airflow that could cause equipment damage or uneven heat dissipation.

[0043] As an optional embodiment, an air inlet 233 is provided between the plurality of baffles 232.

[0044] The air inlet 233 is formed by the gaps between several baffles 232. When air enters from the opening 231, due to the blocking and guiding effect of the baffles 232, the air will enter the cabin through the air inlet 233 between the baffles, forming an orderly airflow. The two sides of the baffles 232 are rotatably connected to the opening 213. By adjusting the angle of the baffles 232, the size and shape of the air inlet 233 can be changed, thereby adjusting the air intake to meet the heat dissipation requirements under different operating conditions.

[0045] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
