[0031] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Please refer to Figures 1 to 8 , Figure 1 This is a schematic diagram of the structure of the first type of high-altitude wind turbine unit provided in the first direction according to the embodiments of this application; Figure 2 This is a cross-sectional view of the first type of high-altitude fan unit provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the first type of high-altitude fan unit provided in the embodiments of this application in the second direction; Figure 4 A partial cross-sectional view of the vibration monitoring device for the first type of high-altitude fan unit provided in the embodiments of this application; Figure 5 A partial structural diagram of the first type of high-altitude fan unit provided in the embodiment of this application at the slot;

The fan inside the fan housing is not shown in any of the aforementioned figures.
[0034] Please refer to Figures 1 to 4 This application provides a high-altitude fan unit, including a fan box, a vibration damping box 2, and a vibration monitoring device 3 installed in the fan box. In this high-altitude fan unit, the fan box includes a fan and a housing. The surface of the housing is provided with ventilation openings to allow airflow to enter and exit the housing, meeting the operating requirements of the fan. The vibration damping box 2 is installed below the fan box, and the top surface of the vibration damping box 2 is attached to and fixedly connected to the bottom surface of the fan box. The vibration damping box 2 supports the fan box and is used to dampen and absorb energy, reducing the vibration of the fan box in the high-altitude working environment and protecting the shafts and other components inside the fan box. The vibration monitoring device 3 is connected to the fan box and is used to detect the vibration status of the fan inside the fan box, providing a safety warning.
[0035] This embodiment employs a vibration damping box 2 and a vibration monitoring device 3 to jointly ensure the safe operation of the fan within the fan housing. The vibration damping box 2 serves both to absorb vibration and energy from the fan housing and its fan, and its enclosure design facilitates installation and disassembly, adapting to the requirements of high-altitude working environments. The vibration monitoring device 3 is located within the fan housing and can be connected to the fan inside, including, but not limited to, sensors connected to the fan shaft. The vibration monitoring device 3 is often used in conjunction with audible and visual alarm elements. When the vibration monitoring device 3 detects that the vibration of the fan housing and its fan exceeds a set range, it can issue a warning to personnel through the aforementioned audible and visual alarm elements, reminding them to promptly inspect and maintain the high-altitude fan unit.
[0036] As mentioned earlier, the vibration damping box 2 is installed inside the high-altitude fan unit in the form of a box. When the vibration monitoring device 3 detects that the vibration state of the fan box and its fan exceeds the set range, it mainly includes two situations: a fault in the vibration damping box 2 and a fault in the fan box. At this time, the faulty equipment can be quickly disassembled and replaced to maintain the high-altitude fan unit. It can be seen that the high-altitude fan unit provided in this application improves the disassembly and assembly performance and working performance of the fan box through the vibration damping box 2 and the vibration monitoring device 3, and is more in line with the various requirements of high-altitude operations.
[0037] The enclosure of this embodiment can be divided into a first enclosure 11 and a second enclosure 12. The second enclosure 12 is attached and fixed to the outer wall of the first enclosure 11. The first enclosure 11 is equipped with a fan, and the second enclosure 12 is equipped with a vibration monitoring device 3. The first enclosure 11 and the second enclosure 12 are each equipped with a door, and the doors face different directions. In addition, a detection channel is provided between the second enclosure 12 and the first enclosure 11, through which the detection part of the vibration monitoring device can pass. The vibration monitoring device 3, which is located in the second enclosure 12, can monitor the fan located in the first enclosure 11 through its detection part.
[0038] The fan and vibration monitoring device 3 are important components of this high-altitude fan unit and are also key areas for maintenance. The fan and vibration monitoring device 3 are respectively housed within the first housing 11 and the second housing 12. Therefore, when maintaining the fan, only the door of the first housing 11 needs to be opened and closed; similarly, when maintaining the vibration monitoring device 3, only the door of the second housing 12 needs to be opened and closed. Separating the fan and vibration monitoring device 3 within the first housing 11 and the second housing 12 provides different operating environments for them, allowing for long-term reliable operation in their respective suitable conditions. It also simplifies the operator's field of vision during maintenance, facilitating quick and easy maintenance of the high-altitude fan unit.
[0039] The high-altitude fan unit provided in this application will be further described below with reference to the accompanying drawings and embodiments.
[0040] In some embodiments, the doors of the first housing 11 and the second housing 12 face different directions, facilitating operators to perform inspection work at different angles of the high-altitude fan unit. Typically, the doors of the first housing 11 and the second housing 12 can be located on opposite sides of the high-altitude fan unit, for example, the door of the first housing 11 can be located on the front side of the high-altitude fan unit, and the door of the second housing 12 can be located on the rear side of the high-altitude fan unit.
[0041] The high-altitude fan unit provided in this application uses a shaft vibration monitor as the vibration monitoring device 3. For example, the vibration monitoring device 3 is specifically an RDXZ-type shaft vibration monitor. Meanwhile, if... Figures 2 to 4 As shown, an alarm 9 connected to a shaft vibration monitor is installed on the outside of the fan housing. For example, the alarm 9 is fixed to the outside of the second housing 12. If the alarm 9 uses optical signals to transmit information, the alarm 9 can be installed on one side of the fan housing or on multiple sides of the fan housing, so that staff can receive information in a timely and effective manner.
[0042] The second housing 12, which is equipped with the shaft vibration monitor 3, can be fixed to the side of the first housing 11 by the mounting block 20. The mounting block 20 increases the contact area between the second housing 12 and the first housing 11, thereby improving the installation strength of the second housing 12 and the shaft vibration monitor.
[0043] The aforementioned shaft vibration monitor has a detection unit that extends from the second housing 12 and is installed in the first housing 11. The detection unit of the shaft vibration monitor can be a sensor or a distance measuring component. The installation of the detection unit within the detection channel between the first housing 11 and the second housing 12 can be a rigid structure of the detection unit extending through the detection channel, a wire of the detection unit extending through the detection channel, or the detection unit transmitting an optical signal through the detection channel.
[0044] Taking the detection unit, including sensors, as an example, the shaft vibration monitor and its sensors can detect the vibration status of the fan in multiple directions. When the detected vibration value reaches the set abnormal vibration value, the controller of the shaft vibration monitor, such as the QYM controller, controls the alarm to sound an alarm and light to remind the staff, so as to promptly remind the staff to check and maintain the various components of the high-altitude fan unit.
[0045] When the shaft vibration monitoring instrument uses sensors as the detection unit, a shaft vibration monitoring instrument may include at least two vibration sensors, which are used to detect the vibration state of the fan shaft in two mutually perpendicular directions.
[0046] In some embodiments, the first housing 11 is provided with ventilation openings. For example, the first housing 11 has a mesh plate 10 on the side of its shock-absorbing box 2, and several holes in the mesh plate 10 allow airflow to enter and exit the shock-absorbing box 2. The mesh plate 10 not only allows for ventilation but also prevents foreign objects from entering the shock-absorbing box 2, thus avoiding damage to the fan inside the shock-absorbing box 2. Of course, the ventilation openings of the first housing 11 can also be configured with other structures.
[0047] Typically, in the high-altitude fan unit provided in this application, the size of the first housing 11 is much larger than the size of the second housing 12; for example, the size of the first housing 11 along any direction of the XYZ three coordinate axes is larger than that of the second housing 12. In addition, the high-altitude fan unit provided in this application also includes a toolbox located on top of the first housing 11. It can be seen that the toolbox, the fan, and the shock absorber 2 are distributed sequentially from top to bottom.
[0048] As the name suggests, a toolbox is used to store tools. These tools can refer to those used for repairing high-altitude wind turbine units, or other tools. A toolbox not only facilitates tool storage and allows workers to operate at heights, but it also provides some safety protection for the wind turbine, preventing damage from falling objects such as rain, snow, and hail.
[0049] Specifically, the aforementioned toolbox can be a pull-out toolbox 7. This pull-out toolbox 7 may include a tray and a horizontal guide rail, with the tray slidably connected to the horizontal guide rail. The tray slides in the inward and outward direction of the toolbox 7, allowing workers to pull the tray out and push it in for easy access to tools. The tray's opening faces upward, preventing tools placed inside from accidentally falling out when the tray is pulled out.
[0050] Typically, the pull-out toolbox 7 can be pulled open in the same direction as the door of either the first housing 11 or the second housing 12. For example, the door of the first housing 11 is located on the front side of the high-altitude fan unit, and the pull-out toolbox 7 is pulled open towards the front side of the high-altitude fan unit and closed towards the rear side of the high-altitude fan unit.
[0051] In the various embodiments provided in this application, both the first housing 11 and the second housing 12 can be made of steel to improve impact resistance. A handle is provided on the outer side of the first housing 11 for easy movement by workers.
[0052] In some embodiments, the first housing used in this application may include a mounting plate 111 and a protective cover 112; the fan is fixed to the upper surface of the aforementioned mounting plate 111, and the fan is fitted with the protective cover 112 facing downwards. In this embodiment, the mounting plate 111 has a first flange 1111 on its periphery, which protrudes towards the side of the high-altitude fan unit. The protective cover 112 has a second flange 1121 on its bottom periphery, which also protrudes towards the side of the high-altitude fan unit. When installing the first housing 11 and the fan, the fan is fixed to the mounting plate 111 and the protective cover 112 is fitted onto the fan facing downwards, so that the first flange 1111 of the mounting plate 111 and the second flange 1121 of the protective cover 112 are aligned and fit together. The first flange 1111 and the second flange 1121 are both provided with positioning holes through which the positioning bolt 16 can pass. The operator can insert the positioning bolt 16 downward into the positioning holes of the first flange 1111 and the second flange 1121 to ensure the installation accuracy of the fan and the first housing 11, thereby ensuring the accurate positioning of the fan and the vibration monitoring device 3 located in the second housing 12.
[0053] In some embodiments, the shock absorber box 2 specifically includes a flat empty box 21 with a plurality of shock absorbers 22 inside; the flat empty box 21 is horizontally distributed, and the plurality of shock absorbers 22 are dispersedly distributed inside the flat empty box 21. All the shock absorbers 22 are installed at the same angle inside the flat empty box 21, and are mainly used to bear the stress in the vertical direction of the flat empty box 21. For example, the shock absorber 22 includes a shock absorber spring, and the length direction of the shock absorber spring is parallel to the vertical direction of the flat empty box 21.
[0054] The shock absorber box 2 and its shock absorber 22 can absorb and reduce the vibration generated during the operation of the high-altitude fan unit, improve the stability of the high-altitude fan unit during operation, and avoid damage to parts caused by excessive vibration of the high-altitude fan unit.
[0055] When assembling the shock absorber box 2 and the first housing 11, the first housing 11 is positioned above the shock absorber box 2, with its bottom surface in contact with the top surface of the shock absorber box 2. The contact surfaces of the bottom surface of the first housing 11 and the top surface of the shock absorber box 2 are within the horizontal projection of all the shock absorbers 22. Therefore, the shock absorber box 2 can effectively support the first housing 11 through its flat, empty box 21, and also effectively transmit the vibration of the first housing 11 to all the shock absorbers 22, thus rationally utilizing the function of the shock absorbers 22.
[0056] Please refer to Figure 3 , Figure 5 and Figure 6In some embodiments, the high-altitude fan unit further includes a slot 4 and a plug 5 respectively disposed on the bottom surface of the first housing 11 and the top surface of the shock-absorbing box 2; the slot 4 and the plug 5 are respectively disposed on the first housing 11 and the shock-absorbing box 2, for example, the plug 5 is disposed on the bottom surface of the first housing 11 and the slot 4 is disposed on the top surface of the shock-absorbing box 2. When the first housing 11 and the shock-absorbing box 2 are assembled using the slot 4 and the plug 5, the slot 4 and the plug 5 can be quickly locked using the limiting bolt 6, thus restricting the degree of freedom of movement of the slot 4 and the plug 5 along the insertion direction.
[0057] For example, the insert 5 located on the bottom surface of the first housing 11 is inserted downward into the slot 4 located on the top surface of the shock absorber 2. The slot 4 and the insert 5 are fixed relative to each other in any direction on the horizontal plane. The limiting bolt 6 can be inserted between the slot 4 and the insert 5 in the horizontal direction to prevent the slot 4 and the insert 5 from moving relative to each other in the insertion direction.
[0058] Multiple inserts 5 can be provided on the bottom surface of the first housing 11, and correspondingly, multiple slots 4 can be provided on the top surface of the shock-absorbing box 2. When the high-altitude fan unit is installed in the designated position, on the one hand, the wind direction in the space where the high-altitude fan unit is located is mostly not opposite to the direction of gravity of the high-altitude fan unit. In other words, the wind direction in the space where the high-altitude fan unit is located is often horizontal or from top to bottom. On the other hand, the first housing 11 is large in volume and mass, and its own weight can counteract the airflow from bottom to top. Therefore, using multiple inserts 5 to be inserted into multiple slots 4 in a one-to-one correspondence helps to ensure the fixed connection strength and stability of the first housing 11 above the shock-absorbing box 2. In addition, the aforementioned installation structure can also simplify the disassembly and assembly of the first housing 11 and the shock-absorbing box 2, which meets the needs of high-altitude operations.
[0059] To suit the operating environment of the high-altitude fan unit, slot 4 and insert 5 are inserted along the height direction. For example, slot 4 is located at the top of the shock absorber box 5 with its opening facing upwards, and correspondingly, insert 5 is located at the bottom of the first box 11 with its protrusion facing downwards. When installing the fan box and the shock absorber box 2, the operator can hoist the fan box above the shock absorber box 2 and align it with slot 4 and insert 5. Then, the hoisted fan box and its first box 11 are continuously lowered until insert 5 is embedded in slot 4. Finally, slot 4 and insert 5 are locked by inserting and locking bolt 6.
[0060] In some embodiments, the high-altitude fan unit may further include a connecting block 23 disposed between the first housing 11 and the shock absorber 2, with the upper and lower surfaces of the connecting block 23 contacting the bottom surface of the first housing 11 and the top surface of the shock absorber 2, respectively. Even if the shapes and sizes of the first housing 11 and the shock absorber 2 differ significantly, the installation requirements of the first housing 11 and the shock absorber 2 can still be met by using the connecting block 23. For example, the upper surface of the connecting block 23 is attached to and fixed to the bottom surface of the first housing 11, and the lower surface of the connecting block 23 is attached to and fixed to the top surface of the shock absorber 2; the lower surface of the connecting block 23 is within the horizontal projection of all the shock absorbers 22. In the aforementioned example, even if the shapes and sizes of the bottom surface of the first housing 11 and the top surface of the shock absorber 2 differ significantly, the support requirements of the first housing 11 can still be met, allowing the shock absorbers 22 to perform their damping function reasonably and effectively.
[0061] Typically, when installing an aerial ventilation fan unit, the vibration damping box 2 of the unit can be fixed to an external structure; that is, the aforementioned external structure supports the aerial ventilation fan unit and its vibration damping box 2 from below. Alternatively, when installing the aerial ventilation fan unit, the first housing 11 or toolbox 7 located at the very top of the unit can also be fixed to the external structure; that is, the aerial ventilation fan unit is suspended below the aforementioned external structure. Furthermore, please refer to... Figure 7 and Figure 8 To improve the installation characteristics of the high-altitude fan unit, it also includes a support base 8 located below the vibration damping box 2. The support base 8 is equipped with a telescopic device 30. One end of the telescopic device 30 faces downwards and is connected to the support base 8, while the other end faces upwards and is connected to the vibration damping box 2. Thus, the telescopic direction of the telescopic device 30 is parallel to the height direction. The aforementioned support base 8 can be fixedly connected to an external mechanism, thereby achieving the positioning and installation of the high-altitude fan unit with the external mechanism. The telescopic device 30 can extend and compress along the height direction, allowing for fine-tuning of the installation height and angle of the high-altitude fan unit based on the external mechanism.
[0062] In the above example, anti-slip blocks 60 can be provided at the bottom of both the shock absorber box 2 and the support base 8. The surface of the anti-slip blocks 60 is provided with anti-slip texture, which can improve the installation stability when an external mechanism is installed on either the shock absorber box 2 or the support base 8.
[0063] In addition, in another specific embodiment of the high-altitude fan unit provided in this application, a mounting bracket 40 can be provided on the outer periphery of the fan box, the shock absorption box 2 and the tool box 7. The mounting bracket 40 realizes the fixed connection of the three in the height direction. Based on the connection relationship between the top surface of the mounting bracket 40 and the external mechanism, the high-altitude fan unit can be hoisted.
[0064] The high-altitude wind turbine unit provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
