Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) platform technology, specifically to an intelligent vibration reduction airport for UAVs used on tower cranes at construction sites. Background Technology

[0002] In recent years, with the deepening of the intelligent transformation of the construction industry, the demand for drone operations such as high-altitude inspection and oblique photogrammetry modeling has become increasingly prominent. At present, the mainstream drone airport technologies are mainly divided into three categories: fixed ground airports, mobile ground airports, and special operation airports. Traditional ground take-off and landing methods have certain limitations. They often face the problem of insufficient space at construction sites to place drone airports. They also require a lot of energy for drone ascent, which makes it difficult for drones to maintain sufficient high-altitude operation time, seriously affecting operation efficiency.

[0003] For example, patent CN218288165U, published on January 13, 2023, discloses a drone airport buffer platform, including: an assembly shell, a support platform disposed on the upper part of the assembly shell; a support block fixed to the bottom of the assembly shell, and a damping spring disposed on one side of the support block; a rubber plate connected to the top of the support block, and a rubber buffer installed on the top of the rubber plate; and a connecting plate connected to the bottom of the support platform. This patent connects several sets of rubber buffers by a connecting plate welded to the bottom of the support platform. At the same time, the rubber plate connected to the support block inside the assembly shell is bonded and fixed to the rubber buffers, which facilitates the dispersion of the impact force of the drone on the support platform when the drone lands, thus playing a buffering role. Meanwhile, the damping spring installed between the support platform and the bottom of the inner wall of the assembly shell plays a shock absorption role, which improves the buffering effect.

[0004] Typically, tower cranes are among the tallest structures on construction sites and remain throughout the entire construction period. To reduce the energy wasted by drones during their ascent, existing construction sites usually set up drone airfields on tower cranes. When a drone takes off from a tower crane, it can directly observe the construction site. However, due to the height of the tower crane, the airfields of drones located on the tower crane often sway under the influence of wind, resulting in poor take-off and landing accuracy and increasing the risk of drones colliding with obstacles. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent vibration-damping airport for unmanned aerial vehicles (UAVs) on tower cranes at construction sites, in order to address the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A smart vibration-damping airport for drones on tower cranes at construction sites includes a control room located on the tower crane. A protective shell is fixedly connected to the top of the control room via pre-embedded bolts. An opening is provided at the upper end of the protective shell, and a sealing component for closing the opening is provided inside the protective shell. A smart leveling and vibration-damping module is provided at the bottom of the protective shell, and a take-off and landing platform is fixedly installed on the smart leveling and vibration-damping module. The smart leveling and vibration-damping module includes four hydraulic columns and four level sensors, which are distributed around the take-off and landing platform. The telescopic ends of the hydraulic columns are connected to the bottom of the take-off and landing platform.

[0007] As mentioned above, a buffer pad is provided between the top of the control room and the bottom of the protective shell.

[0008] The aforementioned take-off and landing platform is made of carbon fiber composite material, and the surface of the take-off and landing platform is covered with an anti-slip and wear-resistant coating.

[0009] As mentioned above, the take-off and landing platform integrates an automatic guidance system and a wireless charging module. The automatic guidance system provides take-off and landing guidance for the drone, and the wireless charging module is used to charge the drone.

[0010] As mentioned above, a solar power supply system is also provided on the top of the protective shell.

[0011] The aforementioned intelligent leveling and vibration reduction module adopts a dual power supply design, including a main power supply that draws power from the control room and a secondary power supply that draws power from the solar power system. The main power supply and the secondary power supply can be switched freely.

[0012] As mentioned above, the top of the protective shell is also equipped with a wind speed meter and a temperature measuring instrument.

[0013] As mentioned above, an intelligent control system is also installed inside the protective shell. The intelligent control system is deeply integrated with the control panel in the control room and shares the display interface.

[0014] As mentioned above, the take-off and landing platform is provided with multiple recesses, each of which corresponds to a support foot of the UAV, and the automatic guidance system is installed in the recesses.

[0015] As mentioned above, a locking mechanism is also provided in the recess, which locks the drone's support feet based on the data from the anemometer.

[0016] The beneficial effects of this utility model are as follows: In the above technical solution, this utility model provides an intelligent vibration reduction airport for drones on tower cranes at construction sites. By setting up an intelligent leveling and vibration reduction module, the horizontal sensor can detect the tilt angle of the platform in real time. The hydraulic column automatically compensates for vibration interference in different directions. It can absorb the instantaneous impact when the drone takes off and lands, and also offset the continuous shaking during the tower crane operation, thus maintaining the stability of the take-off and landing platform and providing a stable working environment for drone high-altitude operations.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the following will be described in conjunction with the appendix. Figure 1-4 This invention will now be described in further detail.

[0021] This utility model embodiment provides an intelligent vibration reduction airport for unmanned aerial vehicles (UAVs) on tower cranes at construction sites, including a control room 1 located on the tower crane. A protective shell 3 is fixedly connected to the top of the control room 1 by pre-embedded bolts 2. An opening 4 is provided at the upper end of the protective shell 3. A sealing component 5 for closing the opening 4 is provided inside the protective shell 3. An intelligent leveling and vibration reduction module 6 is provided at the bottom of the protective shell 3. A take-off and landing platform 7 is fixedly installed on the intelligent leveling and vibration reduction module 6. The intelligent leveling and vibration reduction module 6 includes four hydraulic columns and four level sensors, which are distributed around the take-off and landing platform 7. The telescopic ends of the hydraulic columns are connected to the bottom of the take-off and landing platform 7.

[0022] Specifically, in existing construction sites, drones are typically used for aerial inspections and oblique photogrammetry modeling. When performing aerial inspections and oblique photogrammetry modeling, drones need to climb to a certain height to observe the construction site from above. In order to reduce the energy waste caused by the drone's climbing height, the drone's airfield is usually installed directly on the top of the tower crane. The drone takes off from the top of the tower crane, reducing the required climbing height and allowing the drone to use more energy for on-site observation.

[0023] The shortcomings of existing technology are that, as one of the tallest structures on a construction site, tower cranes are prone to sliding under the influence of strong winds. At this time, the drone airport set on top of the tower crane will also sway synchronously. The swaying drone airport makes it difficult for drones to land accurately in the intended position, which may lead to increased landing deviation, exceeding the safe landing area, and increasing the risk of collision with obstacles.

[0024] To address the aforementioned issues, in this embodiment, the enclosing component 5 includes two baffles and a linear drive mechanism that drives the two baffles to move away from or towards each other. This linear drive mechanism can be a bidirectional electrically controlled telescopic rod, with its two telescopic ends connected to the two baffles respectively. When the drone is not in operation, the two baffles align under the action of the bidirectional electrically controlled telescopic rod, blocking the opening 4 and isolating the internal space of the protective shell 3 from the outside. When the drone needs to operate, the two baffles separate under the action of the bidirectional electrically controlled telescopic rod. As the two baffles gradually move away from each other, the opening 4 at the top of the protective shell 3 gradually opens. 4. When fully opened, the drone flies out of the protective shell 3 through opening 4 to perform inspection work. Among them, four horizontal sensors correspond one-to-one with four hydraulic cylinders. The horizontal sensors are used to monitor the tilt of the landing platform 7, and the horizontal sensors are communicatively connected to the corresponding hydraulic cylinders. When the horizontal sensor detects that the landing platform 7 is tilted, the horizontal sensor sends a working signal to the corresponding hydraulic cylinder. The hydraulic cylinder extends or retracts according to the monitoring data of the corresponding sensor to adjust the landing platform 7 to maintain a horizontal state, counteract the continuous swaying during tower crane operation, and always maintain the stable state of the landing platform 7, providing a stable working environment for the drone's high-altitude operation.

[0025] During operation, tower cranes generate vibrations, which may originate from the crane's mechanical components, wind, or the swaying of the load. When the top of the control room 1 is in direct contact with the protective shell 3, these vibrations can be easily transmitted directly into the protective shell 3, causing the take-off and landing platform 7 inside the protective shell 3 to shake violently, which may affect the take-off and landing stability of the UAV.

[0026] Preferably, a buffer pad 8 is provided between the top of the control room 1 and the bottom of the protective shell 3.

[0027] Specifically, the buffer pad 8 is usually made of materials with good shock absorption performance, strong wear resistance, high temperature resistance, and low temperature resistance, such as rubber pads, silicone pads, polyurethane pads, polytetrafluoroethylene pads, aramid fiber pads, etc. In this embodiment, the buffer pad 8 can be made of rubber. By setting the buffer pad 8 between the top of the control room 1 and the protective shell 3, the buffer pad 8 can absorb and disperse the vibration from the tower crane, thereby reducing the vibration level of the take-off and landing platform 7 inside the protective shell 3, and providing a more stable take-off and landing environment for the UAV.

[0028] Preferably, the take-off and landing platform 7 is made of carbon fiber composite material, and the surface of the take-off and landing platform 7 is covered with an anti-slip and wear-resistant coating.

[0029] Specifically, the platform is made of carbon fiber composite material, which is lightweight and high-strength. The surface is covered with a non-slip and wear-resistant coating with a friction coefficient of ≥0.8. In severe weather (such as rain or strong winds), the surface of the take-off and landing platform 7 can easily become slippery. The non-slip and wear-resistant coating on the surface of the take-off and landing platform 7 can effectively prevent the drone from sliding off the take-off and landing platform 7 during take-off and landing and colliding with the protective shell 3, causing damage to the drone.

[0030] Preferably, the take-off and landing platform 7 integrates an automatic guidance system and a wireless charging module. The automatic guidance system provides take-off and landing guidance for the drone, and the wireless charging module is used to charge the drone.

[0031] Specifically, in this embodiment, the automatic guidance system includes a combination of sensor visual recognition and UWB precise positioning technology, which can provide centimeter-level precision take-off and landing guidance for the drone. This is existing technology, and its principle will not be elaborated here. Furthermore, by integrating a wireless charging module, the drone can be charged when it lands on the take-off and landing platform 7, ensuring the drone's endurance.

[0032] Preferably, the top of the protective shell 3 is also equipped with a solar power supply system 9; the intelligent leveling and vibration damping module 6 adopts a dual power supply design, including a main power supply that draws power from the control room 1 and a secondary power supply that draws power from the solar power supply system 9, and the main power supply and the secondary power supply can be freely switched; the top of the protective shell 3 is also equipped with a wind speed meter 10 and a temperature meter 14, and the protective shell 3 is also equipped with an intelligent control system 11, which is deeply integrated with the operating console in the control room 1 and shares the display interface.

[0033] Specifically, in this embodiment, both the anemometer 10 and the temperature meter 14 are connected to the intelligent control system 11. The anemometer 10 and the temperature meter 14 measure the wind speed and temperature information outside the protective shell 3 and send the measured wind speed and temperature information to the intelligent control system 11. The intelligent control system 11 combines the UAV's battery information to intelligently decide the optimal take-off and landing time. Furthermore, the intelligent control system 11 supports remote monitoring and scheduling.

[0034] It should also be noted that although the intelligent leveling and shock absorption module 6 adjusts the take-off and landing platform 7 in a very short time, it is not completed instantly. After the take-off and landing platform 7 tilts, the drone may slip on the take-off and landing platform 7, causing the drone's position to deviate. The drone with the deviated position is prone to colliding with the protective shell 3 during take-off.

[0035] To solve the above problems, the take-off and landing platform 7 is provided with multiple recesses 12, each of which corresponds to a support foot of the UAV. The automatic guidance system is installed in the recesses 12. A locking mechanism 13 is also provided in the recesses 12. The locking mechanism 13 locks the support foot of the UAV based on the data from the anemometer 10.

[0036] Specifically, the locking mechanism 13 includes two electromagnets 131, which are placed on both sides of the recess 12. When the two electromagnets 131 are energized, they generate a magnetic force that attracts each other (generating a magnetic force that attracts each other when the two electromagnets 131 are energized is existing technology, and its principle will not be elaborated). When the support foot of the drone is inserted into the recess 12, the two electromagnets 131 are placed on both sides of the support foot of the drone. The electromagnets 131 are connected to the inner wall of the recess 12 through springs 132. The electromagnets 131 are electrically connected to the solar power supply system 9. Furthermore, a weight sensor can be installed at the bottom of the recess 12. When the support foot of the drone is inserted into the recess 12, the weight sensor detects the weight of the drone. The intelligent control system 11 of the weight sensor sends a signal, and the intelligent control system 11 causes the solar power supply system 9 to supply power to the electromagnets 131.

[0037] When the drone needs to land, the sealing component 5 causes the two baffles to separate, and the opening 4 at the top of the protective shell 3 opens. At this time, the automatic guidance system located in the recess 12 guides the drone's landing, causing the drone's guide to insert into the corresponding recess 12. When the weight sensor detects the weight of the drone, the weight sensor intelligent control system 11 sends a signal. The intelligent control system 11 enables the solar power system 9 to supply power to the electromagnets 131. The two electromagnets 131 are energized and attract each other, clamping the drone's support feet. At this time, the springs 132 connected to the electromagnets 131 are stretched, accumulating elastic potential energy, which allows the drone to be locked on the take-off and landing platform 7. Even if the take-off and landing platform 7 tilts, the drone will not slide on the take-off and landing platform 7, improving the safety of the drone during take-off. When the drone needs to work, the two electromagnets 131 are de-energized and lose their magnetism. The springs 132 connected to the corresponding electromagnets 131 release the accumulated elastic potential energy. The two electromagnets 131 move away from each other under the pull of the corresponding springs 132, releasing the clamping of the drone's support feet, allowing the drone to leave the take-off and landing platform 7.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
