Description

Technical Field

[0001] This utility model relates to the field of door lock device technology, and in particular to a locking device and a wind turbine tower. Background Technology

[0002] The wind turbine tower is a crucial component of a wind turbine generator set. It bears the weight of the nacelle, blades, and other components, ensuring the stable operation of the entire generator set. Adjusting the tower height allows the wind turbine to operate in the optimal wind resource area, improving power generation efficiency. The tower's design also helps mitigate vibrations and shocks experienced by the wind turbine during operation, extending the unit's lifespan.

[0003] The existing locking devices on wind turbine towers are located on the outside of the tower, requiring manual key unlocking. This is particularly inconvenient in harsh weather conditions, especially in cold winters when the locking devices may become difficult to open due to the cold, causing operational difficulties for maintenance personnel. Most tower locking devices are located outside the tower doors, making them vulnerable to prying and damage due to the remote locations and dispersed layout of the wind turbines, leading to loss of property such as internal cables. Utility Model Content

[0004] The main purpose of this utility model is to propose a locking device and a wind turbine tower, which aims to solve the problem that the tower locking device is located outside the tower door, and because the wind turbine is located in a remote and scattered location, it is easily pried and damaged, resulting in the loss of property such as internal cables of the unit.

[0005] To achieve the above objectives, the present invention proposes a locking device comprising a locking component, a driving component, a power supply component, and a control component. The locking component includes a lock cylinder and a latch, which are movably connected. One of the lock cylinder and the latch is used to connect to the inner wall of the wind turbine tower, and the other is used to connect to the inner wall of the wind turbine tower door. The driving component can drive the lock cylinder to move closer to or away from the latch. The power supply component provides electrical energy to the driving component. The control component has a first control component electrically connected to the driving component. The first control component controls the movement of the driving component from outside the wind turbine tower to lock or separate the lock cylinder from the latch.

[0006] In one embodiment, the lock cylinder is connected to the drive end of the drive member, and the lock cylinder is inserted into the latch.

[0007] In one embodiment, the locking device further includes an elastic element, the two ends of which are respectively connected to the lock cylinder and the drive element.

[0008] In one embodiment, the control assembly has a second control element electrically connected to the drive element, the second control element being used to control the movement of the drive element from within the wind turbine tower.

[0009] In one embodiment, the power supply component includes a backup power connection socket, which is connected to the drive component wire and can be connected to a power source outside the wind turbine tower.

[0010] In one embodiment, the power supply component further includes a cover that is rotatably connected to the wind turbine tower door and blocks the backup power connection socket.

[0011] In one embodiment, the power supply component includes a battery connected to the drive element via wires.

[0012] In one embodiment, the power supply component further includes an AC power source connected to the drive element wires.

[0013] In one embodiment, the locking device further includes a forced unlocking switch located between the power supply component and the drive component, the forced unlocking switch being capable of disconnecting the path between the power supply component and the drive component.

[0014] This utility model also proposes a wind turbine tower, including a locking device.

[0015] This invention provides a locking device comprising a lock cylinder and a latch, movably connected. One of the lock cylinder and latch is connected to the inner wall of the wind turbine tower, and the other to the inner wall of the wind turbine tower door. The locking device also includes a drive component for moving the lock cylinder closer to or further from the latch, thus locking or unlocking. A power supply component provides the necessary electrical energy to the drive component, while a control component includes a first control component electrically connected to the drive component and capable of controlling its movement from outside the wind turbine tower, thereby controlling the locking or unlocking of the lock cylinder and latch. By placing the locking device inside the wind turbine tower, external prying and vandalism can be effectively prevented, protecting internal assets such as cables from damage. Since the control component allows control from outside the tower, this design not only improves security but also increases operational convenience, especially in harsh weather conditions. Maintenance personnel can unlock the door without direct contact with the lock, reducing the difficulty of opening the lock due to cold weather and minimizing potential injuries from manual unlocking. In addition, this design reduces the chances of thieves committing crimes because the door lock is no longer exposed, thereby improving the safety and reliability of the entire wind turbine.

[0025] This utility model proposes a locking device 100.

[0026] Please see Figures 1 to 2 In one embodiment of this utility model, the locking device 100 includes a locking component 1, a driving component 2, a power supply component 3, and a control component 4. The locking component 1 includes a lock cylinder 11 and a latch 12, which are movably connected. One of the lock cylinder 11 and the latch 12 is used to connect to the inner wall of the wind turbine tower, and the other is used to connect to the inner wall of the wind turbine tower door. The driving component 2 can drive the lock cylinder 11 to move closer to or away from the latch 12. The power supply component 3 is used to provide electrical energy to the driving component 2. The control component 4 has a first control component 41, which is electrically connected to the driving component 2. The first control component 41 is used to control the movement of the driving component 2 from outside the wind turbine tower so that the lock cylinder 11 is locked or separated from the latch 12.

[0027] In this embodiment, the locking component 1 consists of a lock cylinder 11 and a latch 12, which are connected by a movable connection to allow relative movement during operation. Specifically, one end of either the lock cylinder 11 or the latch 12 is fixedly or detachably mounted on the inner wall of the wind turbine tower, while the other end is fixedly or detachably mounted on the inner wall of the wind turbine tower door. The lock cylinder 11 and the latch 12 can be a shaft and hole insertion structure or a rotating arm and groove fitting structure. The driving component 2 can be an electric motor or a cylinder device, connected to the lock cylinder 11 via a mechanical connection (such as a gear, chain, or slider), enabling the lock cylinder 11 to move closer to the latch 12 to lock the door or move away from the latch 12 to unlock the door when needed. The power supply component 3, such as a battery pack 33 or an external power source, provides the necessary electrical energy to the driving component 2 via a wire connection to ensure that the driving component 2 can operate normally. This design makes the locking device 100 safer and more reliable because the movable connection between the lock cylinder 11 and the latch 12 allows for flexible locking and unlocking operations, while the electric or pneumatic operation of the drive unit 2 reduces the need for manual operation and improves the convenience and efficiency of operation.

[0028] The first control unit 41 in control component 4 can be a remote control, a control panel installed on the outside of the tower, or a mobile device application connected via a wireless network. This first control unit 41 is electrically connected to the drive unit 2 (such as an electric motor) via a wireless signal, allowing the user to remotely control the movement of the drive unit 2 from outside the wind turbine tower. By operating the first control unit 41, the user can send commands to activate the drive unit 2, thereby driving the lock cylinder 11 closer to the latch 12 to lock, or to move the lock cylinder 11 away from the latch 12 to unlock. This design provides a way to operate without direct contact with the locking device 100, greatly improving the convenience and security of operation. Especially in harsh weather conditions, maintenance personnel do not need to be exposed outside the tower, reducing operational difficulties and security risks caused by weather conditions. Furthermore, remote control reduces reliance on physical keys, lowering the risk of lost or stolen keys. Electronic control also enables more precise access control and recording, improving the security of the wind turbine tower and preventing illegal intrusion and potential theft. At the same time, this control method also provides a foundation for intelligent management of the wind turbine tower, contributing to the automation and information management of wind farms.

[0029] The technical solution of this utility model involves designing a locking device 100, which includes a lock cylinder 11 and a latch 12, movably connected. One of the lock cylinder 11 and the latch 12 is connected to the inner wall of the wind turbine tower, and the other is connected to the inner wall of the wind turbine tower door. The locking device 100 also includes a drive component 2, used to drive the lock cylinder 11 closer to or further away from the latch 12 to achieve locking or unlocking. A power supply component 3 is responsible for providing the necessary electrical energy to the drive component 2, while a control component 4 includes a first control component 41, which is electrically connected to the drive component 2 and can control the movement of the drive component 2 from outside the wind turbine tower, thereby controlling the locking or unlocking of the lock cylinder 11 and the latch 12. By placing the locking device 100 on the inner side of the wind turbine tower, external prying and vandalism can be effectively prevented, thus protecting the cables and other property inside the wind turbine tower from damage. Because control component 4 allows for control from outside the tower, this design not only improves security but also increases operational convenience, especially in harsh weather conditions. Maintenance personnel can unlock the doors without direct contact with the locks, reducing difficulties in opening locks due to cold weather and minimizing potential injuries from manual unlocking. Furthermore, this design reduces the opportunity for thieves, as the locks are no longer exposed, thus enhancing the overall security and reliability of the wind turbine.

[0030] In one embodiment of this utility model, please refer to Figure 1 The lock cylinder 11 is connected to the drive end of the drive component 2, and the lock cylinder 11 is inserted into the latch 12.

[0031] In one embodiment, the lock cylinder 11 and the driving end of the drive member 2 are fixedly or detachably connected by a mechanical connection (such as a threaded connection, pin connection, flange connection, etc.). This connection method ensures that the drive member 2 can directly transmit power to the lock cylinder 11, causing it to move accordingly. Simultaneously, the insertion between the lock cylinder 11 and the latch 12 is achieved through a hole-shaft structure, allowing the lock cylinder 11 to smoothly insert into or remove from the latch 12 under the action of the drive member 2, completing the locking and unlocking actions. This design makes the operation of the locking device 100 simpler and more reliable. The mechanical connection method ensures the efficiency and stability of power transmission between the lock cylinder 11 and the drive member 2, reducing the risk of failure due to unstable connection. Furthermore, the plug-in design of the lock cylinder 11 and latch 12 makes the locking and unlocking process smoother, reducing operational difficulties caused by friction or jamming. In addition, this design also improves the security of the locking device 100, because the door can only be locked when the lock cylinder 11 is correctly inserted into the latch 12, increasing the difficulty of illegal intrusion. At the same time, this design also facilitates the maintenance and replacement of the lock cylinder 11 or the latch 12, as they can be easily disassembled and reinstalled, thereby reducing maintenance costs and improving maintenance efficiency.

[0032] In one embodiment of this utility model, please refer to Figure 1 The locking device 100 also includes an elastic element 5, with the two ends of the elastic element 5 connected to the lock cylinder 11 and the driving element 2, respectively.

[0033] In this embodiment, the locking device 100 further includes an elastic element 5, one end of which is connected to the lock cylinder 11, and the other end is connected to the driving element 2. This connection can be achieved through threaded connection or welding, etc. The elastic element 5, such as a spring, can provide the necessary elastic force, allowing the lock cylinder 11 to smoothly engage or disengage with the latch 12 under the action of the driving element 2. For example, a helical spring can be used, with one end fixed to the lock cylinder 11 and the other end fixed to the driving element 2. When the driving element 2 is subjected to an electrical signal or mechanical force, the extension and contraction of the spring drives the lock cylinder 11 to move, thereby locking or unlocking the lock cylinder 11 and the latch 12. The addition of the elastic element 5 provides buffering and vibration absorption functions, reducing the impact force during the engagement of the lock cylinder 11 and the latch 12, thereby extending the service life of the lock. In addition, the elastic element 5 can also compensate for errors in the manufacturing and assembly process to a certain extent, improving the reliability and stability of the lock. During operation, the elastic force of the elastic element 5 helps the lock cylinder 11 smoothly engage with the latch 12, reducing jamming and making the operation of the locking device 100 smoother. At the same time, this design also improves the security of the lock, because the elastic element 5 can absorb some energy under external impact, reducing the risk of the lock being pried open.

[0034] In one embodiment of this utility model, please refer to Figure 1 The control component 4 has a second control element 42, which is electrically connected to the drive element 2 and is used to control the movement of the drive element 2 from inside the wind turbine tower.

[0035] In one embodiment, the second control element 42 serves as an internal control unit, electrically connected to the drive element 2. This connection can be a direct wire connection or a connection achieved through an internal communication network such as a CAN bus or wireless communication technology. The second control element 42 can be an operation panel installed inside the wind turbine tower, allowing maintenance personnel to directly operate the panel from inside the tower to control the movement of the drive element 2, thereby locking or unlocking the lock cylinder 11 and the latch 12. This design allows for locking operations directly from inside the tower without external intervention. This internal control method improves the security of the locking device 100 because it reduces the impact of external factors such as severe weather or potential unauthorized intrusion on the locking operation. Simultaneously, internal control reduces the risks for maintenance personnel operating outside the tower, especially during high-altitude operations, where internal control provides better protection. Furthermore, this design reduces the likelihood of locking device 100 malfunctions due to external physical damage, thereby improving the reliability and stability of the wind turbine tower.

[0036] In one embodiment of this utility model, please refer to Figure 1 The power supply component 3 includes a backup power connection socket 31, which is connected to the drive component 2 wires. The backup power connection socket 31 can be connected to a power source outside the wind turbine tower.

[0037] In this embodiment, the power supply component 3 includes a backup power connection socket 31, designed to provide power support when the main power supply is unavailable. The backup power connection socket 31 is connected to the drive component 2 via a wire, ensuring that the backup power supply can quickly take over the power supply task when the main power supply fails. The backup power connection socket 31 is located outside the wind turbine tower, facilitating access to an external power source, such as a portable battery bank 33 or a generator. When the main power supply fails or requires maintenance, maintenance personnel can quickly connect an external power source to ensure the normal operation of the locking device 100. This design improves the reliability and continuity of the locking device 100 because the backup power supply ensures the normal operation of the locking device 100 even when the main power supply is faulty, avoiding safety risks and operational interruptions caused by power problems. The use of a backup power supply makes the locking device 100 more stable and reliable in the face of unexpected situations. Furthermore, this design improves the ease of maintenance because maintenance personnel can quickly switch to the backup power supply, reducing downtime caused by power problems and improving the operating efficiency of the wind farm.

[0038] In one embodiment of this utility model, please refer to Figure 1 The power supply component 3 also includes a cover 32, which is rotatably connected to the wind turbine tower door and blocks the backup power connection socket 31.

[0039] In one embodiment, the cover 32 in the power supply component 3 is designed to be rotatably connected to the wind turbine tower door. This design allows the cover 32 to open when needed to expose the backup power connection socket 31, and to close when not needed to cover the backup power connection socket 31. The connection between the cover 32 and the tower door can be achieved through a pivot or hinge structure. The pivot can be a fixed point on the tower door, and the cover 32 is connected to the pivot through a bearing or other rotating mechanism, thereby realizing the rotational opening and closing function of the cover 32. The backup power connection socket 31 is located on the cover 32. When the cover 32 is closed, the socket is covered by the cover 32, thus providing protection. This design improves the safety and protection of the backup power connection socket 31, preventing damage to the socket caused by environmental factors such as rain and dust, and also preventing unauthorized personnel from accessing or damaging the backup power connection socket 31. Furthermore, the rotating connection design of the cover 32 allows for easy opening and connection when backup power is needed, while closing it when not in use maintains the integrity and aesthetics of the tower door. This design also helps reduce power connection problems caused by external factors, improving the reliability and stability of the wind turbine tower.

[0040] In one embodiment of this utility model, please refer to Figure 1 The power supply component 3 includes a battery 33, which is connected to the drive component 2 by wires.

[0041] In this embodiment, the battery 33 is directly connected to the drive unit 2 via wires to provide the required electrical energy. This connection can be a direct electrical connection, where the positive and negative terminals of the battery 33 are connected to the corresponding power input terminals of the drive unit 2 via wires. To ensure the stability and safety of the connection, dedicated terminals, soldering, or plug-in methods can also be used to achieve the electrical connection between the battery 33 and the drive unit 2. Furthermore, the battery 33 can be fixed in a protective housing or battery holder to prevent physical damage and environmental influences, ensuring a long-term stable power supply from the battery 33.

[0042] In one embodiment of this utility model, please refer to Figure 1 The power supply component 3 also includes an AC power supply 34, which is connected to the drive component 2 via wires.

[0043] In one embodiment, the AC power supply 34 in the power supply assembly 3 can be connected to the conductors of the drive unit 2 via a standard power cord. This connection typically involves connecting the output terminals of the AC power supply 34 to the input terminals of the drive unit 2 to ensure the correctness and safety of the electrical connection. In some cases, an adapter or transformer may be required to match the power supply voltage and the operating voltage of the drive unit 2 to ensure a stable power supply.

[0044] In one embodiment of this utility model, please refer to Figure 1 The locking device 100 also includes a forced unlocking switch 6 located between the power supply component 3 and the drive component 2, which can disconnect the passage between the power supply component 3 and the drive component 2.

[0045] In this embodiment, the locking device 100 includes a forced unlocking switch 6, which is designed as a physical switch located between the power supply component 3 and the drive component 2. This switch can be directly connected to the circuitry of the power supply component 3 and the drive component 2, or via a control module. Under normal operation, the switch remains closed, allowing current to flow from the power supply component 3 to the drive component 2, thus enabling the locking device 100 to function normally. When forced unlocking is required, the operator can manually or remotely activate this switch to disconnect the circuit, thereby cutting off the power supply path between the power supply component 3 and the drive component 2, achieving forced unlocking. This design provides a safety mechanism that can quickly cut off the power supply in emergency situations or when the locking device 100 malfunctions. The presence of the forced unlocking switch 6 ensures that the lock can be quickly released when needed, facilitating emergency access or maintenance. Furthermore, this design improves system safety because it allows for rapid power cut-off in abnormal conditions, preventing potential electrical fires or equipment damage.

[0046] This utility model also proposes a wind turbine tower, which includes a locking device 100. The specific structure of the locking device 100 is as described in the above embodiments.
