Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a wind turbine tower cover device and a wind turbine tower. Background Art

[0002] A wind turbine tower is the mast of a wind turbine generator system, primarily providing support for the wind turbine generator set and absorbing vibrations. A wind turbine tower cover is a device installed atop the wind turbine tower, primarily protecting the cables and equipment inside the tower. It typically consists of a cover body, screw holes, bolts, hooks, manholes, support edges, and connecting edges. The cover body has a downward-folded edge on the outer edge, a hook on the upper surface, a manhole in the middle, and upward-raised support and connecting edges on the edges. A connecting edge is located inside the top of the support edge and is secured by bolts.

[0003] When operating personnel enter the wind turbine cabin, hub and other locations to deal with faults, they need to ascend on the non-climbing device inside the tower. Every time they pass a tower section, they need to manually push open the wind turbine cover of each tower section. After passing the cover, they need to go to the tower platform to close the cover and continue climbing. When there is maintenance work, personnel need to open and close the tower cover while climbing the tower. This process is time-consuming and affects the maintenance progress.

However, it is easy for workers to accidentally approach and cause the tower covers to be suddenly opened or closed, which may easily cause all wind turbine tower covers to be directly opened, which is extremely unsafe.

[0044] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0046] First, let’s explain the terms involved in this application:

[0047] Wind energy: Wind energy refers to the kinetic energy generated by the movement of large amounts of air over the Earth's surface. Due to varying temperatures and water vapor content in the air, atmospheric pressure varies across the Earth's surface. Horizontally, high-pressure air flows toward low-pressure areas, creating wind. Wind energy resources are determined by wind energy density and the cumulative number of hours of available wind energy per year. Wind energy density is the wind power available per unit windward area and is proportional to the cube of wind speed and air density.

[0048] Wind turbine tower: The wind turbine tower is the tower of wind power generation, which plays a major supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of wind turbine tower is generally as follows: CNC cutting machine cuts the material, thick plates need to be beveled, the plate rolling machine rolls the plate into shape, spot welds, positions, and confirms the welding of internal and external longitudinal seams. After the roundness is checked, if there is a problem, a second rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the internal and external circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the welds are carried out. After sandblasting and painting, the internal parts are installed and the finished product is inspected, and then it is transported to the installation site.

[0049] Microcontroller Unit (MCU): Also known as a single-chip microcomputer or single-chip microcomputer, it reduces the frequency and specifications of the central processing unit (CPU) and integrates memory, timers, USB, A / D converters, UARTs, PLCs, DMA and other peripheral interfaces, and even LCD driver circuits on a single chip, forming a chip-level computer that can provide different control combinations for different applications.

[0050] When operators enter a wind turbine tower to address complex equipment failures, they must ascend vertically using a climbing aid installed inside the tower. During this process, operators must pause after each tower section and manually open the wind turbine cover covering each tower section. This step is not only laborious but also time-consuming. After passing through the cover, they must return to the tower platform and close it again, ensuring safety before continuing to climb. Especially during emergency maintenance work, this cover opening and closing operation undoubtedly increases the time cost for personnel to climb the tower, affecting the overall progress of the maintenance work.

[0051] To address this issue, existing technologies attempt to achieve automatic opening and closing of wind turbine tower covers by installing basic sensors and other intelligent devices. These devices automatically trigger the cover to open or close when detecting specific signals. However, this automated solution has exposed safety risks in actual application. If the sensor sensitivity is improperly set or there is a false triggering, the tower cover can suddenly open or close when a worker inadvertently approaches. This could not only cause personal injury, but also allow all covers on the entire wind turbine tower to be opened without authorization, seriously threatening on-site safety management.

[0052] To address the aforementioned technical issues, the present invention provides a wind turbine tower cover device. By adding a sensing device 4 to detect maintenance personnel passing by a ladder 3, control assembly 2 drives movable panel 11 to open when the personnel pass by. This sensor triggers the cover's opening and closing, creating a safety protection device that automatically opens and closes the cover. This device, designed for use with a ladder, addresses the inconvenience of operators manually opening and closing the cover, improving maintenance efficiency while ensuring safety.

[0053] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0054] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a wind turbine tower cover device and a wind turbine tower, comprising: a cover 1, a control component 2, a ladder 3 and a sensing device 4; a movable plate 11 is provided on the cover 1, a first accommodating space 12 is provided on the movable plate 11, and the ladder 3 is provided through the first accommodating space 12; the sensing device 4 is provided at a preset position of the ladder 3, and the sensing device 4 is used to detect whether there are operation and maintenance personnel passing by the ladder 3; the control component 2 is provided on the cover 1 and connected to the sensing device 4, and the control component 2 is used to control the opening or closing of the movable plate 11; wherein, when the movable plate 11 is opened, a second accommodating space 13 is formed on the cover 1.

[0055] Among them, the cover plate 1 serves as the basic part of the entire device, and is used to cover and protect the entrance or other openings of the tower; the movable plate 11 is arranged on the cover plate 1, which can be moved to open or close the cover plate, and the movable plate 11 can allow operation and maintenance personnel to provide a passage when needed; the ladder 3 runs through the first accommodating space 12, and can provide a passage for operation and maintenance personnel to go up and down the wind turbine tower; the sensing device 4 is installed at a preset position of the ladder 3, and can be used to detect whether there are operation and maintenance personnel passing by. The sensing device 4 can be an infrared sensor, a pressure sensor or other type of detection equipment, and this application does not impose any restrictions; the control component 2 is arranged on the cover plate 1 and is connected to the sensing device 4, and can be used to control the opening and closing of the movable plate 11 according to the detection results of the sensing device.

[0056] As will be appreciated, a movable panel 11 is provided on the cover plate 1 so that it can be flexibly switched between open and closed positions to accommodate the needs of maintenance personnel entering and exiting the wind turbine tower. A first accommodation space 12 is provided on the movable panel 11. The size and shape of the accommodation space are just large enough to allow the ladder 3 to pass through it, with a certain gap, thereby ensuring the ladder's stability and penetration.

[0057] Optionally, to precisely control the opening and closing of the movable panel 11, a sensing device 4 is installed at a preset position on the ladder 3. This sensing device can detect in real time whether an operator is passing by. Once the presence of an operator is detected, the sensing device immediately sends a signal to the control component 2, triggering the corresponding control logic. For example, this may control the opening of the movable panel 11 to form a second receiving space 13, allowing the operator to enter the wind turbine tower through this second receiving space 13.

[0058] Control assembly 2, the control hub of the entire device, is mounted on cover plate 1 and communicates with sensing device 4 via a reliable connection, such as wires or signal transmission. This solution does not restrict the connection method. Upon receiving a signal from sensing device 4, control assembly 2 reacts to the signal and, through a series of complex mechanical or electronic operations, switches movable panel 11 between open and closed states.

[0059] It should be noted that when the movable panel 11 is in the open position, a second receiving space 13 is formed on the cover 1. The size and shape of this space are sufficient for smooth passage of maintenance personnel, greatly simplifying the process of entering and exiting the tower and improving work efficiency. Furthermore, because the entire device utilizes automated control, the operational difficulty and safety risks for maintenance personnel are greatly reduced.

[0060] Specifically, when the sensing device 4 detects that an operator is passing by, the control component 2 triggers the movable panel 11 to open, thereby forming a second receiving space 13 on the cover 1 to allow the operator to pass through. After the operator passes through, the movable panel 11 can be closed to restore the protective function of the cover 1.

[0061] like Figure 1 and Figure 2 As shown, in a possible implementation, the sensing device 4 includes a first sensing device and a second sensing device; the first sensing device and the second sensing device are respectively arranged on the upper and lower sides of the cover plate 1; wherein, if the first sensing device is arranged at a first preset position on the upper side of the cover plate 1, the second sensing device is arranged at a second preset position on the lower side of the cover plate 1; if the first sensing device is arranged at the first preset position on the lower side of the cover plate 1, the second sensing device is arranged at the second preset position on the upper side of the cover plate 1.

[0062] Among them, the first sensing device and the second sensing device can be different types of sensors or the same type of sensors, and can be set according to the actual internal environment of the wind turbine tower, such as infrared sensors, ultrasonic sensors or other suitable detection equipment. This solution will not be elaborated here, and is mainly used to detect the presence and movement of operation and maintenance personnel.

[0063] It is understood that if the first sensing device is installed at the first preset position on the upper side of the cover plate 1, the second sensing device will be installed at the second preset position on the lower side of the cover plate 1; conversely, if the first sensing device is installed at the first preset position on the lower side of the cover plate 1, the second sensing device will be installed at the second preset position on the upper side of the cover plate 1. This symmetrical installation method ensures that no matter which direction the maintenance personnel approach the cover plate, the sensing device can effectively detect their presence, improves detection accuracy, and provides reliable operation under different environmental conditions.

[0064] Specifically, if the first sensing device is set at the first preset position on the upper side of the cover 1, then the second sensing device is correspondingly set at the second preset position on the lower side of the cover 1. In practice, when the operation and maintenance personnel climb up the ladder 3, the first sensing device will be triggered first, and then the second sensing device may be triggered again in the process of passing through the cover 1.

[0065] Correspondingly, if the first sensing device is set at the first preset position on the lower side of the cover plate 1, the second sensing device will be set at the second preset position on the upper side of the cover plate 1. This layout is suitable for situations where maintenance personnel approach the cover plate from below, such as when they evacuate downward along the ladder 3.

[0066] Through this dual-component, opposing-sensing design, the wind turbine tower cover device of the present application can achieve all-round, multi-angle detection of the passage of operation and maintenance personnel, thereby more accurately controlling the opening and closing of the movable panel 11. This multi-level detection mechanism improves the safety and reliability of the system, ensuring that the movable panel can be opened in a timely manner when operation and maintenance personnel need to pass through, and remains closed when they are not needed.

[0067] like Figure 1 、 Figure 2 and Figure 3 As shown, in a possible implementation, the control component 2 includes: an MCU controller 21 and a drive unit 22, the drive unit 22 is used to drive the movable panel 11 to switch between an open state and a closed state; the MCU controller 21 is connected to the drive unit 22; the MCU controller 21 and the drive unit 22 are respectively connected to the movable panel 11 in a transmission manner; the MCU controller 21 is used to control the drive unit 22 to drive the movable panel 11 to switch from a closed state to an open state when the detection information is determined to have passed based on the sensing information sent by the first sensing device.

[0068] The MCU controller 21 is a microcontroller that processes signals from the sensing device 4. After the MCU controller 21 receives the sensing information sent by the sensing device 4, it can analyze and determine it. When the MCU controller determines that it has detected the passage of an operator, it sends a command to the drive unit 22 to control the state switching of the movable panel 11.

[0069] The drive unit 22 is used to actually open and close the movable panel 11. The drive unit 22 receives instructions from the MCU controller 21 and drives the movable panel 11 to switch between an open state and a closed state. The drive unit 22 may include, for example, an electric motor, a hydraulic system, or other suitable drive mechanism to ensure smooth and reliable operation of the movable panel 11.

[0070] It can be understood that the MCU controller 21 and the driving unit 22 are respectively connected to the movable plate 11 in a transmission manner, which means that they can directly affect the physical movement of the movable plate. This connection method ensures that the control signal can be quickly and accurately converted into mechanical action.

[0071] Specifically, when the operator approaches the cover 1, the sensing device 4 detects the operator's entry and sends corresponding sensing information to the MCU controller 21. After receiving the sensing information, the MCU controller 21 can perform a logical judgment on it. If the MCU controller determines that passage information has been detected, that is, the operator is approaching or has approached to the extent that the movable panel 11 needs to be opened, the MCU controller 21 can control the drive unit 22 and send a command to the drive unit 22, instructing it to drive the movable panel 11 from the closed state to the open state.

[0072] After receiving the instruction, the driving unit will start the corresponding mechanical action, push or pull the movable panel 11, so that it gradually opens from the closed state, providing a passage space for the operation and maintenance personnel.

[0073] Optionally, for example, when the first sensing device detects the approach or passage of an operator, the MCU controller 21 will quickly respond by instructing the drive unit 22 to open the movable panel 11, forming the second accommodation space 13 for the operator to pass through. After the operation is completed, the device can automatically close the movable panel 11 under preset conditions, such as a period of time after the operator leaves, to restore the protective function of the cover.

[0074] like Figure 1 、 Figure 2 and Figure 3 As shown, in a possible implementation, the MCU controller 21 is further configured to control the driving unit 22 to drive the movable panel 11 to switch from the open state to the closed state after a preset period of time when a passing message sent by the second sensing device is detected.

[0075] After receiving the passing message from the second sensing device, the MCU controller 21 does not immediately close the movable panel, but waits for a preset period of time. This preset period can be adjusted according to specific needs to ensure that the movable panel 11 will not close until the person has completely passed, thereby avoiding misoperation or injury to people.

[0076] As you can understand, when maintenance personnel approach the wind turbine tower cover assembly, they first trigger the first sensing device. This component immediately sends a sensing signal to the MCU controller 21, indicating that maintenance personnel are approaching. Upon receiving this signal, the MCU controller 21 initiates the appropriate logic and controls the drive unit 22 to switch the movable panel 11 from the closed state to the open state, providing clearance for maintenance personnel.

[0077] As the operator continues to move, they will then trigger the second sensing device. This component will also send a sensing signal to the MCU controller 21, but this time the signal means that the operator has passed or is leaving the cover area.

[0078] It should be noted that upon receiving this second sensing signal, the MCU controller 21 does not immediately control the movable panel to close. Instead, it initiates a preset delay period. The length of this delay period can be adjusted based on actual needs and safety considerations to ensure that maintenance personnel have sufficient time to safely pass through and exit the covered area. After the delay period expires, the MCU controller 21 controls the drive unit 22 to switch the movable panel 11 from the open state back to the closed state, thereby restoring the cover's safety protection function.

[0079] In one possible implementation, the logic within the MCU controller 21 can be configured based on a variety of factors, such as the movement speed of the operator, the size of the cover area, and safety standards. The specific length of the preset time period should be adjusted based on actual conditions to ensure that safety requirements are met without affecting the operator's work efficiency.

[0080] At the same time, in order to ensure the stability and reliability of the system, a redundant design or a fault detection mechanism may be used between the MCU controller 21 and the drive unit 22 to prevent system failure due to a single point failure.

[0081] like Figure 1 、 Figure 2 and Figure 3 As shown, in a possible implementation, the MCU controller 21 is further configured to receive a sensing message sent by the sensing device 4; if the MCU controller 21 does not receive a sensing message sent by the sensing device 4 within a preset time period, a pass message is generated.

[0082] Wherein, when no sensing message is received, the MCU controller 21 can automatically generate a passing message. This passing message triggers the driving unit 22 to open or keep the movable panel 11 open at an appropriate time to ensure that the operation and maintenance personnel can pass smoothly.

[0083] It is understood that if the MCU controller 21 does not receive any sensing information from the sensing device 4 within a preset time period, it will assume that no maintenance personnel are currently active near the cover area. In this case, the MCU controller will automatically generate a passing message. In other words, even though no maintenance personnel have actually passed through, the "passing message" here can be understood as a virtual signal for triggering the closing of the movable panel.

[0084] After generating the pass information, the MCU controller controls the drive unit 22 to drive the movable plate 11 from the open state to the closed state, thereby restoring the safety protection function of the cover. The introduction of this mechanism provides a backup judgment standard to ensure that the device can still make a reasonable response even if the sensing device 4 fails to detect normally.

[0085] like Figure 1 、 Figure 2 and Figure 3 As shown, in a possible implementation, the movable panel 11 includes: a first movable panel and a second movable panel; a first accommodating space 12 is provided on the first movable panel and the second movable panel, and there is a gap between the first accommodating space 12 and the ladder 3; the bottoms of the first movable panel and the second movable panel are respectively connected to the driving unit 22 by transmission, and under the driving action of the driving unit 22, the first movable panel and the second movable panel are respectively opened to the left and right directions to form a second accommodating space 13, and the second accommodating space 13 is used to enable operation and maintenance personnel to enter the wind turbine tower through the cover plate 1.

[0086] The first and second movable panels together form the overall structure of the movable panel 11. The first and second movable panels can be moved left and right, respectively, to open or close the passage. A first accommodating space 12 is provided between the first and second movable panels to accommodate the ladder 3. A gap exists between the first accommodating space and the ladder to ensure that the ladder's stability and safety are not affected when the movable panels are moved.

[0087] As can be understood, the drive unit 22 is responsible for controlling the movement direction and state transitions of the two movable panels. When the first and second movable panels are opened to the left and right respectively by the drive unit 22, a new space, namely the second accommodation space 13, is formed between them and between them and the rest of the cover panel 1. The second accommodation space 13 provides sufficient passage space for operation and maintenance personnel so that they can safely enter the interior of the wind turbine tower through the cover panel 1.

[0088] like Figure 1 and Figure 4 As shown, in a possible implementation, the sensing device 4 is an infrared sensor, including: a transmitting end 41 and a receiving end 42, and the transmitting end 41 and the receiving end 42 are respectively arranged at preset positions on both sides of the ladder 3; the transmitting end 41 is used to send infrared signals, and the receiving end 42 is used to receive the infrared signals sent by the transmitting end 41. When the receiving end 42 can receive the infrared signal, it is determined that no operation and maintenance personnel have passed by on the current ladder 3; when the receiving end 42 does not receive the infrared signal, it is determined that there are operation and maintenance personnel passing by on the current ladder 3, and the sensing information is sent to the MCU controller 21, so that the MCU controller 21 controls the movable panel 11 to open and form the second accommodating space 13.

[0089] The transmitter 41 can emit infrared signals, while the receiver 42 can receive them. The transmitter and receiver are mounted opposite each other at predetermined positions on either side of the ladder, forming a detection channel for the infrared signal. When maintenance personnel pass by the ladder, the infrared signal is blocked, allowing the sensor 4 to sense the signal and emit a sensing signal.

[0090] It can be understood that when the receiving end 42 can receive the infrared signal sent by the transmitting end 41, the system determines that no operation and maintenance personnel are passing by on the current ladder; correspondingly, when the receiving end 42 fails to receive the infrared signal, it means that an operation and maintenance personnel has passed by because the operation and maintenance personnel blocked the transmission of the signal.

[0091] As can be seen from the above, when the receiving end 42 detects the passage of an operator, that is, when the receiving end does not receive a signal, the receiving end 42 will send sensing information to the MCU controller 21. After receiving this information, the MCU controller 21 will control the driving unit 22 to drive the movable panel 11 to open, thereby forming the second accommodation space 13 and providing a passage for the operator.

[0092] By utilizing infrared sensor technology, the sensing device 4 can accurately and in real time detect maintenance personnel passing through the ladder 3, improving the safety of the wind turbine tower cover assembly and ensuring smooth passage for maintenance personnel during work. Furthermore, the intelligent control logic within the MCU controller 21 enables more precise and efficient opening and closing of the movable panel 11. This not only reduces the workload for maintenance personnel but also improves the overall operational efficiency of the wind turbine tower.

[0093] like Figure 1 and Figure 3 As shown, in a possible implementation, the two movable plates 11 are arc-shaped plates, and the upper surface of the cover plate 1 is an arc-shaped surface.

[0094] Compared to flat panels, curved panels offer greater structural stability. When subjected to external forces, they can better disperse and resist these forces, reducing the risk of structural damage.

[0095] It can be understood that in order to enable the movable panel 11 to be tightly closed with the cover panel 1, the movable panel 11 is also designed as an arc-shaped panel. When the movable panel 11 is in a closed state, its arc-shaped surface can fit more closely with the arc-shaped upper surface of the cover panel 1, thereby improving the sealing performance. At the same time, it also helps to prevent rainwater, dust and other debris from entering the wind turbine tower, protecting the internal equipment and environment.

[0096] like Figure 1 As shown, in a possible implementation, a wind turbine tower cover device and a wind turbine tower further include: an alarm device 5;

[0097] The alarm device 5 is arranged on the side of the ladder 3. The alarm device 5 is used to issue an alarm prompt when the working state of the wind turbine tower cover device is abnormal.

[0098] Among them, the alarm device is set on the side of the ladder 3. This position makes it easy for operation and maintenance personnel to see or hear the alarm prompt in time when going up and down the tower, which can ensure that the alarm signal can be conveyed to on-site personnel at the first time.

[0099] It is understood that the alarm device can be used to monitor the operating status of the wind turbine tower cover assembly. When an abnormality is detected, such as the inability of the movable panel to open or close normally, a sensor failure, or a malfunction of the drive unit, the alarm device will issue an audible or visual alarm or other form of prompt. The alarm device can use a variety of prompting methods, such as a buzzer, a warning light, or wireless signal transmission to a remote monitoring center, and this solution does not limit these.

[0100] Specifically, the alarm device 5 is typically connected to the MCU controller 21 and triggers the alarm function by receiving an abnormality signal sent by the MCU controller. The MCU controller 21 determines whether the device's operating status is abnormal based on feedback from the sensing device 4 and other sensors, and sends an alarm signal to the alarm device 5 if an abnormality is confirmed.

[0101] Alarm device 5 can promptly detect and report abnormal conditions in the wind turbine tower cover assembly, thereby avoiding potential safety accidents. Through various alarm methods, such as sound and light, operation and maintenance personnel can immediately notice abnormal conditions and take necessary emergency measures. Furthermore, the alarm prompts from alarm device 5 can help operation and maintenance personnel quickly locate the fault point, thereby shortening troubleshooting time, improving equipment maintenance efficiency, and reducing economic losses caused by downtime.

[0102] Through real-time monitoring and alarm prompts, the reliability and stability of the wind turbine tower cover device have been improved. This helps to extend the service life of the equipment, reduce maintenance costs, and improve overall operation and maintenance efficiency.

[0103] In a possible implementation, a wind turbine tower includes a wind turbine tower cover device according to various possible implementations described above.
