[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The tower usually refers to the tower part of the wind turbine, which is an important structure supporting the entire wind turbine. As a connecting component between the wind turbine and the foundation ring, the tower can withstand the gravity load of the nacelle, hub, blades, etc. above, the vibration load caused by the wind rotor, and the environmental wind load. It is an important component required to realize the functions of wind turbine maintenance, power transmission and transformation.

[0047] At present, the internal structure of the tower consists of the main shaft, generator, inverter and lubrication system. In order to ensure the safe operation of the wind turbine generator set, a series of safety protection measures have been taken in the tower, including the lightning protection device equipped in the tower to protect the wind turbine generator set from the impact of lightning strikes, and the tilt detection device installed in the tower to detect the verticality of the tower, timely detect the tilt or displacement of the tower, and prevent structural instability.

[0048] However, this traditional tower structure does not have the function of automatically detecting the safety situation inside the tower, and cannot detect whether there are illegal persons breaking into the tower and causing damage to the wind turbine generator set. It also does not have an automatic door closing function, and has a low safety factor.

[0049] To this end, the present application provides a tower structure and a wind turbine generator set, which detects the information of people entering the tower structure by setting a safety detection component inside the tower structure, and connects a controller to the safety detection component to transmit the information detected by the safety detection component to the controller, and the controller controls the actuator to make corresponding actions; and by setting a driving mechanism and a door magnetic sensor on the safety door, the tower can be automatically locked when no one is inside. Compared with the traditional tower structure, the tower structure can automatically detect the safety situation inside the tower and has higher safety performance.

[0050] A tower structure in this embodiment is further described below.

[0051] Figure 1 It is a schematic diagram of the structure inside a tower structure provided in an embodiment of the present application; Figure 2 It is a structural schematic diagram of a safety door in a tower structure provided in an embodiment of the present application.

[0052] like Figure 1 As shown, the embodiment of the present application provides a tower structure, including: a tower body 100, a safety detection component 200 and a controller 300; the tower body 100 has a receiving chamber 110, and a safety door 400 that can be opened and closed is provided on the side wall of the tower body 100; the safety detection component 200 is arranged in the receiving chamber 110, and the safety detection component 200 includes an entry and exit information detection component 210 and a temperature detection component 230, and the entry and exit information detection component 210 and the temperature detection component 230 are both connected to the controller 300 by signal, and the entry and exit information detection component 210 is configured to detect the personnel information entering the receiving chamber 110, and transmit the personnel information to the controller 300;

[0053] The safety door 400 includes a driving mechanism 410 and a door magnetic sensor 420. Figure 2 As shown, the driving mechanism 410 and the door magnetic sensor 420 are both connected to the controller 300. When the entry and exit information detection component 210 detects that there is no one in the accommodating chamber 110 and the door magnetic sensor 420 detects that the safety door 400 is open, the controller 300 controls the safety door 400 to close.

[0054] Among them, the door magnetic sensor 420 is arranged above the safety door 400. The door magnetic sensor 420 detects the internal situation of the tower structure 10 and sends the detection result to the controller 300. When the door magnetic sensor 420 detects that there is no one in the tower structure 10, it will send a low-level signal, and the controller 300 receives the signal of the door magnetic sensor 420. When the door magnetic sensor 420 continues to output the low-level signal for a period of time, the controller 300 determines that there is no one in the tower structure 10, and the controller 300 controls the safety door 400 to close.

[0055] Specifically, the safety door 400 can be connected to the terminal. When the controller 300 determines that there is no one inside the tower structure 10, it sends a user notification message to the terminal, and the manager completes a one-key door closing operation through the terminal device.

[0056] The safety door 400 may also be provided with an access control system, that is, the safety door 400 may be opened only during working hours to prevent personnel from entering the tower structure 10 during non-working hours, thereby increasing potential safety hazards.

[0057] Among them, the type of security door 400 can be a password lock, fingerprint lock, etc., which has high security performance and only allows staff to enter the tower structure 10, preventing non-staff from entering the tower structure 10 to cause safety hazards.

[0058] In some embodiments, the safety detection component 200 further includes an alarm, and the alarm, the access information detection element 210 and the controller 300 are electrically connected.

[0059] In some embodiments, the type of the entry and exit information detection element 210 can be a facial recognition sensor. When the facial recognition sensor detects that the person entering the tower structure 10 is not a staff member, the controller 300 controls the alarm system (not shown in the figure) to send an alarm message to the terminal. Specifically, the terminal can be a computer or a mobile phone. The management personnel can receive the alarm information anywhere and grasp the safety situation in the tower structure 10 in time.

[0060] In some embodiments, the entry and exit information detection element 210 is arranged above the safety door 400. The purpose of such arrangement is to have a wider field of view and to be able to comprehensively detect the information of people entering and exiting the safety door 400. When a person enters the tower structure 10 from the safety door 400, the entry and exit information detection element 210 will generate a detection signal and transmit the generated detection signal to the controller 300, so that the information of people entering the tower structure 10 can be detected earlier so that corresponding safety measures can be taken in time.

[0061] In some embodiments, the safety detection component 200 further includes a monitoring component 220 , which is electrically connected to the controller 300 ; the monitoring component 220 is configured to monitor the personnel entering the accommodating chamber 110 in real time.

[0062] When a person enters the detection range of the entry and exit information detection element 210, the entry and exit information detection element 210 generates an electrical signal based on the detected signal, and sends the electrical signal to the controller 300 via a cable or wirelessly. After the controller 300 receives the electrical signal sent by the entry and exit information detection element 210, it determines that a person has entered, and the controller 300 sends a command to the monitoring element 220, starts the monitoring element 220 to record in real time, and transmits the video data to the central monitoring system. Specifically, the video data can be stored locally or in the cloud for subsequent viewing and analysis.

[0063] In some embodiments, the safety detection component 200 further includes a light source 240 , which is electrically connected to the controller 300 . The controller 300 is configured to control the on and off of the light source 240 according to the signal obtained from the access information detection component 210 .

[0064] Among them, since the height of the tower structure 10 is relatively high, the interior of the tower structure 10 is relatively dark. In order to more clearly capture the walking trajectory of the personnel, a light source 240 is arranged in the accommodating cavity 110. Specifically, the type of the light source 240 is an induction lamp, and the induction lamps are arranged at circumferential intervals along the accommodating cavity 110. When someone walks under the induction lamp, the controller 300 controls the induction lamp to turn on.

[0065] Among them, an emergency light is also provided inside the tower structure 10. The purpose of such provision is to provide reliable lighting in an emergency situation to ensure the safety of personnel and the normal operation of the equipment inside the tower structure 10. Specifically, the emergency light is provided near the safety door 400.

[0066] In some embodiments, the tower body 100 includes a plurality of partitions 130 , which are arranged at intervals along the extension direction of the accommodating cavity 110 and divide the accommodating cavity 110 into a plurality of sub-cavities 120 ;

[0067] A pressure sensor 140 is disposed on each of the isolation layers 130 , and the pressure sensor 140 is electrically connected to the controller 300 .

[0068] When a person stands on the isolation layer 130, pressure will be applied to the pressure sensor 140, and the sensitive elements inside the pressure sensor 140 will undergo physical changes, which will be converted into electrical signals. By measuring the changes in these electrical signals, the position and size of the applied pressure can be determined to judge which layer of isolation layer 130 the person has reached.

[0069] Specifically, there are multiple pressure sensors 140, and the multiple pressure sensors 140 are evenly arranged in a matrix on the isolation layer 130. Each pressure sensor 140 corresponds to a specific position. When a person stands on the pressure sensor 140, the pressure sensors 140 at different positions will detect different pressure values. Each pressure sensor 140 converts the detected pressure value into an electrical signal and transmits it to the controller 300. The controller 300 processes and analyzes the collected pressure data. Based on the collected pressure data, the controller 300 calculates the specific position of the person.

[0070] In some embodiments, at least one of a monitoring component 220 and a light source 240 is disposed in each sub-cavity 120 .

[0071] Among them, as an optional implementation, only a monitoring component 220 is provided in each sub-cavity 120. The monitoring component 220 can be an infrared camera, a thermal imaging camera, or other camera that can take clear images in a dark environment. This embodiment does not impose any restrictions on this.

[0072] Among them, as another optional implementation, only a light source 240 is set in each sub-cavity 120, so that the status of electrical and other equipment in each sub-cavity 120 can be clearly observed, and non-staff entering the tower structure 10 and destroying the electrical components inside the tower structure 10 can be observed for subsequent maintenance.

[0073] Among them, as another optional implementation, a light source 240 and a monitoring device 220 are provided in each sub-cavity 120, and the light source 240, the monitoring device 220 and the pressure sensor 140 are all connected to the controller 300. When a person stands on the partition 130, the pressure sensor 140 generates a signal, and the pressure sensor 140 transmits the signal to the controller 300. The controller 300 controls the light source 240 and the monitoring device 220 to turn on synchronously, thereby playing a role of real-time monitoring. Through real-time video transmission, the user can monitor the situation inside each sub-cavity 120 in real time, and promptly discover and deal with problems.

[0074] The temperature detection element 230 is connected to the controller 300 . When the temperature detection element 230 detects that the temperature is greater than or equal to a preset value, the controller 300 controls the light source 240 and the monitoring element 220 to turn on, and the monitoring element 220 collects images in the accommodating cavity 110 .

[0075] Among them, the electrical equipment inside the tower structure 10 must have suitable operating conditions to work stably for a long time. High temperature will cause the performance of electrical components to decline. Low temperature will cause the functions and parameters of capacitors, inductors, resistors, and batteries to change, accelerate material embrittlement, and seriously affect the working stability and reliability of the equipment. Therefore, the temperature detection member 230 is set inside the tower structure 10 to detect the temperature inside the tower structure 10 so as to regulate the temperature inside the tower structure 10.

[0076] Among them, the tower structure 10 is equipped with a large number of transmission cables, control cables, frequency converter cabinets and control cabinets. When the insulation of the transmission cables and control cables is aged after long-term operation, the cable joints are loose, which may easily lead to increased contact resistance or short circuit, or due to poor ventilation of the frequency converter cabinets and control cabinets and aging of electrical components, fire may occur.

[0077] Among them, in order to prevent the tower structure 10 from catching fire and causing great economic losses, the temperature detection component 230, the monitoring component 220 and the controller 300 are connected. When the temperature value detected by the temperature detection component 230 is greater than the preset value, the controller 300 controls the monitoring component 220 to turn on, and the monitoring component 220 transmits the captured image to the central controller. The staff determines whether there is a fire based on the captured image and takes corresponding fire-fighting measures.

[0078] In some embodiments, a lifting device 150 is also provided in the accommodating cavity 110. The lifting device 150 is provided along the extension direction of the accommodating cavity 110. A distance detection component 160 is provided on the lifting device 150. The distance detection component 160 is electrically connected to the controller 300. The distance detection component 160 is configured to detect the height of the distance lifting device 150 from the ground.

[0079] As an optional implementation, the lifting device 150 is an elevator. After entering the tower structure 10 , people can take the elevator to reach each sub-cavity 120 .

[0080] The distance detection element 160 may be an infrared distance sensor, an ultrasonic distance sensor, etc., which is not limited in this embodiment. Specifically, the distance detection element 160 is fixedly arranged at one end of the elevator facing the sub-cavity 120, and the distance between the elevator and the ground is calculated according to the time difference between the sending signal and the receiving signal of the distance detection element 160, so as to track the position of the person.

[0081] The tower structure 10 is further provided with a staircase 170, which is arranged along the extension direction of the accommodation cavity 110. Figure 1As shown, after a person enters the tower structure 10, there are two ways to reach the partition 130, the first is to take an elevator to a designated location, and the second is to climb to a target area via stairs 170. In order to capture the location information of the person in all directions, a monitoring device 220 can be set near the stairs 170.

[0082] Among them, since the tower structure 10 is at a high height and the wind speed is relatively high, in order to ensure that the safety door 400 is not damaged in extreme weather and to improve the stability of the safety door 400, in this embodiment, the material of the safety door 400 is high-strength steel.

When the access information detection member 210 detects that the accommodating chamber 110 is in an unmanned state, and the door magnetic sensor 420 detects that the safety door 400 is open, the controller 300 controls the safety door 400 to close. In this way, by setting the safety detection component 200 inside the tower structure 10, the information of the personnel entering the tower structure 10 is detected, and the controller 300 is connected to the safety detection component 200, and the information detected by the safety detection component 200 is transmitted to the controller 300, and the controller 300 controls the actuator to make corresponding actions, and by setting the driving mechanism 410 and the door magnetic sensor 420 on the safety door 400, it can be automatically locked when there is no one inside the tower. Compared with the traditional tower structure 10, this tower structure 10 can automatically detect the safety situation inside the tower and has higher safety performance. Compared with the traditional tower structure, this structure can automatically detect the safety situation inside the tower structure 10 and has higher safety performance.
