Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a tower door for wind power generation. Background Technology

[0002] In existing technologies, wind energy is the kinetic energy generated by the movement of large amounts of air across the Earth's surface. Differences in temperature due to solar radiation and variations in water vapor content in the air create pressure differences across the land. This causes high-pressure air to flow horizontally towards low-pressure areas, forming wind. Wind energy resources are determined by wind energy density and the annual cumulative number of usable wind energy hours. Wind turbine towers are the supports used in wind power generation, primarily serving a supporting function within the wind turbine generator set, while also absorbing vibrations from the unit.

[0003] The tower door is located at the bottom of the wind turbine tower and is the only entrance for routine maintenance inside the wind turbine. Wind turbines are usually installed in farmland or high mountains, so if anyone enters the wind turbine tower, it will cause a safety hazard.

[0004] In view of the above problems, there is an urgent need for a new type of wind power tower gate to solve the aforementioned technical problems. Utility Model Content

[0005] In view of this, this application provides a tower gate for wind power generation. The main objective is to solve the technical problem of facilitating the maintenance of the tower gate while eliminating safety hazards.

[0006] According to the present invention, a wind power generation tower door is provided, comprising: a door frame, wherein the door frame is hinged with a double door, the double door comprising: an inner door panel and an outer door body;

[0007] The inner door panel is connected to the door frame via a door closer;

[0008] A pull rod is provided on the side of the inner door panel that connects to the outer door body. One end of the pull rod is connected to the inner door panel, and the other end of the pull rod passes through the outer door body. Its end is vertically and rotatably connected to a limit rod. The limit rod and the end of the pull rod are rotatably connected by a rotating shaft, and the axis of the rotating shaft is consistent with the length direction of the limit rod.

[0009] A countersunk groove is provided on the outer door body at the position corresponding to the pull rod. The bottom of the countersunk groove is provided with a limiting strip hole that matches the limiting rod. The limiting rod extends into the countersunk groove through the limiting strip hole and rotates around the rotating axis. When the limiting rod rotates to abut against the groove wall of the countersunk groove, the limiting rod is engaged in the countersunk groove.

[0010] Furthermore, an alarm device and a battery compartment for the alarm device are installed on the inner door panel, and the battery compartment contains a battery;

[0011] A pull rope is connected to the outer door. One end of the pull rope is connected to the outer door, and the other end is connected to an insulating plate. The insulating plate is inserted into the end of the battery in the battery compartment.

[0012] Furthermore, one side of the countersunk groove is connected to the cover plate via a hinge, and the other end of the cover plate is connected to the other side of the countersunk groove via a locking device.

[0013] Furthermore, the width of the inner door panel is smaller than the width of the outer door body, and the alarm device and the battery compartment are installed on the side of the inner door panel away from the outer door body.

[0014] Furthermore, a pull handle is provided on one side of the outer door body that is the same as the cover plate, and one end of the pull rope is connected to the inner side of the outer door body corresponding to the pull handle.

[0015] Furthermore, the other end of the pull cord is connected to the insulating insert via a guide assembly passing through the inner door panel.

[0016] Furthermore, the guide assembly includes a bracket and rollers. The bracket is provided with a first roller and a second roller. The first roller is fixedly connected to the inner door panel. The second roller is arranged parallel to the first roller on the same horizontal line. The first roller and the outer peripheral wall of the second roller are in rolling contact.

[0017] Furthermore, after the pull rope passes through the gap between the two rollers, its two ends are respectively connected to the insulating insert and the outer door body.

[0018] Furthermore, the battery compartment is provided with a socket, and the insulating plug is inserted into the battery compartment through the socket to disconnect the circuit;

[0019] The jack is designed with the opening facing the guide assembly.

[0020] Furthermore, in the initial state, the limiting rod is parallel to the limiting strip hole. When the outer door is pulled, the limiting rod disengages from the limiting strip hole, causing the outer door and the inner door panel to separate.

[0021] This utility model provides a wind turbine tower door. By employing a unique double-layer door control structure, under normal circumstances, when unauthorized personnel attempt to pull the outer door, the inner door panel will not be pulled due to the special connection design between the two layers. At this time, the movement of the outer door will pull the pull rope, causing it to be pulled out of the battery compartment's socket, thereby activating the alarm device's circuitry and emitting an alarm sound. This timely and effective alarm mechanism can quickly alert surrounding personnel to unauthorized entry attempts, greatly enhancing the safety of the wind turbine tower and ensuring the safety of equipment and personnel inside the tower.

[0022] For authorized personnel, simply use a key to unlock the door, open the cover, and then rotate the limit lever until it is not parallel to the limit strip hole to release the restriction between the two doors. At this point, pulling the outer door will open both the outer and inner doors simultaneously, allowing personnel to easily enter the tower for their work. The entire operation requires no complicated steps or tools, greatly improving personnel access efficiency. The inner door panel is narrower than the outer door, and the alarm device and battery compartment are installed on the side of the inner door panel away from the outer door. This ingenious structural design makes full use of the tower door space and avoids mutual interference between components. It ensures the normal operation of the double-door connection and separation structure while providing a suitable installation location for the alarm device.

[0034] Example

[0035] like Figure 1-3 As shown, a wind power generation tower door includes: a door frame 3, the door frame being hinged with a double door, the double door including: an inner door panel 1 and an outer door body 2;

[0036] The inner door panel 1 is connected to the door frame 3 via a door closer 18, ensuring that the inner door panel 1 can automatically close after being opened;

[0037] A pull rod 4 is provided on the side of the inner door panel 1 that connects to the outer door body 2. One end of the pull rod 4 is connected to the inner door panel 1, and the other end of the pull rod 4 passes through the outer door body 2. Its end is vertically and rotatably connected to a limit rod 5. The limit rod 5 and the end of the pull rod 4 are rotatably connected by a rotating shaft, and the axis of the rotating shaft is consistent with the length direction of the limit rod 5.

[0038] A countersunk groove 6 is provided on the outer door body 2 at the position corresponding to the pull rod 4. The bottom of the countersunk groove 6 is provided with a limiting strip hole 7 that is adapted to the limiting rod 5. The limiting rod 5 extends into the countersunk groove 6 through the limiting strip hole 7 and rotates around the rotating axis. When the limiting rod 5 rotates to abut against the groove wall of the countersunk groove 6, the limiting rod 5 is engaged in the countersunk groove 6, thereby realizing the connection and fixation of the double door.

[0039] In this application, the locking structure between the limiting rod 5 and the countersunk groove 6 provides a stable connection when double-layer doors are required, effectively preventing accidental loosening or separation between the outer door 2 and the inner door panel 1. This ensures the stability and safety of the tower door during normal use and resists interference from external wind forces and other factors. Furthermore, the limiting rod 5 can rotate around its axis, allowing for easy release of the locking mechanism when the double doors need to be separated. This simple and intuitive operation allows staff to quickly and flexibly control the connection status of the double doors according to actual needs, improving work efficiency. Finally, the overall structure of the tower door in this application is compact, making full use of the door space. The layout of each component is reasonable, and the connection structure does not increase the door's volume or affect its normal opening and closing function.

[0040] In this embodiment, an alarm device 8 is installed on the inner door panel 1. Specifically, the alarm device is a buzzer alarm, and the alarm device 8 has a battery compartment 9, which contains a battery.

[0041] A pull rope 10 is connected to the outer door 2. One end of the pull rope 10 is connected to the outer door 2, and the other end is connected to an insulating insert 11. Specifically, the other end of the pull rope 10 is connected to the insulating insert 11 via a guide assembly passing through the inner door panel 1.

[0042] The insulating insert 11 is inserted into the battery end inside the battery compartment 9, at which point the alarm circuit is disconnected. In this application, when unauthorized personnel attempt to pull the outer door 2, due to the special structure between the double doors, the inner door panel 1 will not be pulled. The movement of the outer door 2 will pull the pull rope 10, causing the insulating insert 11 to be pulled out from the battery end. The buzzer alarm circuit will instantly conduct, emitting a loud alarm sound. This timely and effective alarm mechanism can quickly alert surrounding personnel to any unauthorized entry attempts, greatly enhancing the safety of the wind power tower and effectively preventing unauthorized personnel from entering, thus ensuring the safety of equipment and personnel inside the tower. For authorized personnel, when entering the tower, they only need to follow the normal operating procedure to first unlock and separate the double doors (e.g., by rotating the limit rod 5). At this time, the outer door 2 and the inner door panel 1 can open simultaneously. During the opening process, because it is an authorized operation, the alarm device will not be triggered, allowing personnel to smoothly enter the tower to carry out relevant work. The entire operation process is both safe and convenient.

[0043] In addition, the reusable design of the insulating plug plate 11 not only reduces the cost of using the equipment and the cost of frequent replacements due to alarm damage, but also improves the reliability and stability of the equipment, extends the service life of the equipment, and facilitates the daily maintenance and repair of the equipment.

[0044] In this embodiment, the guide assembly includes a bracket 15 and a roller 16. The bracket 15 is provided with a first roller and a second roller. The first roller is fixedly connected to the inner door panel 1. The second roller is arranged parallel to the first roller on the same horizontal line. The first roller and the outer peripheral wall of the second roller are in rolling contact.

[0045] In this embodiment, one side of the countersunk groove 6 is connected to the cover plate 12 via a hinge, and the other end of the cover plate 12 is connected to the other side of the countersunk groove 6 via a locking member 13.

[0046] In one feasible implementation, the width of the inner door panel 1 is smaller than the width of the outer door 2, and the alarm device 8 and the battery compartment 9 are installed on the side of the inner door panel 1 away from the outer door 2. This layout ensures a simple overall appearance of the door while also fully considering the functionality and maintenance convenience of each component.

[0047] In one feasible implementation, a pull handle 14 is provided on the same side of the outer door body 2 as the cover plate 12, and one end of the pull rope 10 is connected to the inner side of the outer door body 2 corresponding to the pull handle 14.

[0048] In this embodiment, the other end of the pull rope 10 is connected to the insulating insert plate 11 via a guide assembly passing through the inner door panel 1. After passing through the gap between the two rollers, the two ends of the pull rope 10 are respectively connected to the insulating insert plate 11 and the outer door body 2.

[0049] In one feasible implementation, the battery compartment 9 is provided with a socket 17, and the insulating insert 11 is inserted into the battery compartment 9 through the socket 17 to disconnect the circuit; the socket 17 is configured to open towards the guide assembly to facilitate the detachment of the insulating insert 11.

[0050] In this embodiment, in the initial state, the limiting rod 5 is parallel to the limiting strip hole 7. When the outer door 2 is pulled, the limiting rod 5 disengages from the limiting strip hole 7, causing the outer door 2 and the inner door panel 1 to separate. Specifically, in use, the initial state of the limiting rod 5 is that the limiting rod 5 and the limiting strip hole 7 are parallel. When the outer door 2 is pulled, the limiting rod 5 can disengage from inside the limiting strip hole 7, thereby causing the outer door and the inner door panel to separate. The outer door can then pull the pull rope 10. When workers need to enter for work or maintenance, they open the lock with a key and then open the cover plate 12, rotating the limiting rod 5 to a state that is not parallel or perpendicular to the limiting strip hole 7. At this time, the inner door panel 1 can be pulled simultaneously when the outer door panel is opened, allowing workers to enter for maintenance.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
