Description

Technical Field

[0001] This utility model relates to the field of lifting gimbal technology, specifically a lifting gimbal for all models of aircraft cabin radar. Background Technology

[0002] In the nacelle of a wind turbine, nacelle-mounted wind-measuring lidar plays a crucial role in the stable operation and efficient power generation of the wind power system. The gimbal, as a key structure mounted on the top of the nacelle, directly affects the effectiveness of the lidar.

[0003] Currently, commonly available gimbals have many limitations when used for nacelle radar installation. Firstly, different wind turbine models have significantly different nacelle structures and turbine hub heights and sizes. Traditional fixed-model gimbals, due to their fixed height and structure, are often only suitable for installing radar on the nacelle of a specific wind turbine model, failing to meet the universal requirements of multiple models. Customizing gimbals of different heights and specifications for different wind turbine models would not only significantly increase R&D, production, and procurement costs but also prolong the entire project implementation cycle and reduce work efficiency.

[0004] On the other hand, in actual installation, to ensure that the radar beam is not blocked by the wind turbine hub, the height of the gimbal sometimes needs to reach about two meters or even higher. This undoubtedly greatly increases the difficulty and risk of high-altitude installation operations, placing extremely high demands on the skills of the operators and safety measures, while also increasing the potential economic losses and safety hazards caused by installation difficulties.

[0005] In summary, the existing nacelle radar gimbal structure can no longer meet the current wind power industry's requirements for efficient, low-cost, and safe installation. There is an urgent need for a new type of liftable gimbal structure that can adapt to all wind turbine models and is easy to install and operate to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a liftable gimbal for all aircraft models of cabin radar.

[0007] The technical solution adopted by this utility model is: a liftable gimbal for all aircraft models of cabin radar, comprising:

[0008] Three support rods are arranged in a triangular pattern. Each support rod includes a middle sleeve, end sleeves fitted on both ends of the middle sleeve, and an adjusting flange threaded onto the middle sleeve. Both the middle sleeve and the end sleeves are provided with connecting plates, and each of the two end sleeves is provided with a flange for installation and fixing.

[0009] A triangular frame, the ends of which are fixedly connected to the connecting plate.

[0010] Furthermore, the connecting plate and the triangular frame are fixed together by welding or by bolts.

[0011] Furthermore, a reinforcing plate is provided between the flange and the end sleeve.

[0012] Furthermore, a radar bracket is provided at the upper end of the end sleeve, and a second flange that is compatible with the first flange is provided at the bottom of the radar bracket.

[0013] Furthermore, the radar bracket includes a connecting rod, an adjusting disc, an adjusting base plate, and a radar mounting plate. The two ends of the connecting rod are respectively hinged to the flange and the adjusting disc. The adjusting disc is provided with an arc groove. The fixing bolts on the adjusting base plate pass through the arc groove and are connected to the adjusting disc.

[0014] Furthermore, a lower connecting plate is provided on the adjusting base plate, an upper connecting plate is provided on the radar mounting plate, a second arc groove is provided on the lower connecting plate, a fixing bolt on the upper connecting plate passes through the second arc groove and is connected to the lower connecting plate, and a positioning bolt is also provided between the upper connecting plate and the lower connecting plate above the second arc groove.

[0015] The beneficial effects of this utility model are:

[0016] 1. Reduced Usage Costs: This patented height-adjustable gimbal eliminates the traditional model of customizing gimbals for different camera models. Through a single height-adjustable structural design, it meets the needs of various camera models, reducing the cost of developing and producing gimbals separately for different models. Furthermore, it eliminates the need to stock different specifications of gimbals for each model, significantly reducing inventory and management costs and improving resource utilization efficiency.

[0017] 2. Enhanced Applicability: The three support rods arranged in a triangle, along with the design of the adjusting flange and connecting plate, allow for flexible adjustment of the overall height of the pan-tilt head. Regardless of the significant differences in wheel height and size among different models, the height adjustment function can adapt to various usage requirements.

[0018] 3. Enhanced Safety: During installation, the gimbal can be initially installed at a lower height, reducing the difficulty and risk of working at height and ensuring the personal safety of installation personnel. After initial installation and fixation, the gimbal can be raised by adjusting the flange to reach the ideal working height, which not only meets the equipment's operational requirements but also effectively avoids safety hazards caused by an excessively high initial installation height.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides a retractable gimbal for all models of aircraft with a cabin radar.

[0028] In this embodiment, refer to Figure 1-4 The cabin radar features a retractable gimbal for all models, including:

[0029] Three support rods 1 are arranged in a triangular pattern. Each support rod 1 includes a middle sleeve 2, end sleeves 3 fitted on both ends of the middle sleeve 2, and an adjusting flange 4 threaded onto the middle sleeve. Both the middle sleeve and the end sleeves are provided with connecting plates 5, and both end sleeves are provided with flanges 6 for installation and fixing.

[0030] The triangular frame 7 is fixedly connected at its end to the connecting plate.

[0031] In the above technical solution, the design of three triangularly distributed support rods utilizes the stability principle of triangles to provide a stable support structure for the pan-tilt unit, ensuring its stability under various operating conditions and preventing the radar's wind measurement accuracy from being affected by swaying or displacement. The combination of the middle sleeve, end sleeve, and adjusting flange allows for flexible adjustment of the pan-tilt unit height via rotating the adjusting flange, meeting the requirements of different wind turbine hub heights. The connecting plate facilitates the connection and fixing of various components, while the flange at the end of the end sleeve facilitates the installation and fixing of the pan-tilt unit to the nacelle and also facilitates radar installation, simplifying the installation process.

[0032] As shown in the attached diagram of the instruction manual, the adjusting flange abuts against the end sleeve, and the adjusting flange is threadedly connected to the middle pipe section (the adjusting flange has an internal thread, and the middle pipe section has an external thread). By rotating the adjusting flange, the end sleeve can be adjusted and moved, thereby achieving height adjustment.

[0033] Specifically, the connecting plate and the triangular frame are fixed together by welding or by bolts.

[0034] In this embodiment, the connecting plate and the triangular frame are fixed together by welding or bolting. Welding allows the two to form a whole, providing high connection strength and stability, effectively preventing loosening due to vibration or other factors during fan operation. Bolted connections offer the advantages of convenient installation and disassembly, facilitating later maintenance and component replacement, and improving the maintainability of the equipment.

[0035] Specifically, a reinforcing plate 8 is provided between the flange and the end sleeve.

[0036] In this embodiment, a reinforcing plate is installed between the flange and the end sleeve, increasing the strength and rigidity of the connection and enabling it to withstand greater external forces and torques. This not only improves the stability of the gimbal installation but also extends its service life and reduces the risk of failure due to damage to the connection.

[0037] Specifically, a radar bracket 9 is provided at the upper end of the end sleeve, and a flange 10 adapted to flange 6 is provided at the bottom of the radar bracket 9.

[0038] In this embodiment, a radar bracket is provided at the upper end of the end sleeve, and a second flange that matches the first flange is provided at the bottom of the radar bracket, thus achieving a stable connection between the radar and the pan-tilt unit. This design allows the radar to be accurately mounted on the pan-tilt unit, ensuring that it maintains the correct position and attitude during the pan-tilt unit's raising and lowering process, guaranteeing the accuracy of the radar's emitted light, and thereby improving the reliability of wind measurement.

[0039] Specifically, the radar bracket includes a connecting rod 11, an adjusting disc 12, an adjusting base plate 13, and a radar mounting plate 14. The two ends of the connecting rod are respectively hinged to the flange and the adjusting disc. The adjusting disc is provided with an arc groove 15. The fixing bolts on the adjusting base plate pass through the arc groove 15 and are connected to the adjusting disc.

[0040] In this embodiment, the radar support includes a connecting rod, an adjusting disc, an adjusting base plate, and a radar mounting plate. The arcuate groove on the adjusting disc engages with the fixing bolts on the adjusting base plate, allowing for angle adjustment of the adjusting disc within a certain range. This enables the radar mounting plate to adjust its angle according to actual needs, further optimizing the radar's detection angle and improving the measurement accuracy for different wind directions and speeds.

[0041] Specifically, a lower connecting plate 16 is provided on the adjusting base plate, an upper connecting plate 17 is provided on the radar mounting plate, a second arc groove 18 is provided on the lower connecting plate 16, a fixing bolt on the upper connecting plate passes through the second arc groove 18 and connects with the lower connecting plate, and a positioning bolt 19 is also provided between the upper connecting plate and the lower connecting plate above the second arc groove 18.

[0042] In this embodiment, the lower connecting plate on the adjusting base plate and the upper connecting plate on the radar mounting plate are connected by fixing bolts and a second arc groove. A positioning bolt is provided above the second arc groove. This design allows the radar mounting plate to be finely adjusted within a certain range to adapt to different installation environments and measurement requirements. The positioning bolts, after being adjusted, serve to fix the radar mounting plate, ensuring its stability during operation and preventing positional changes from affecting the radar's measurement results.

[0043] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
