Description

Technical Field

[0001] This application relates to the field of aviation safety technology, specifically to a self-installing aviation warning ball, installation system, and installation method. Background Technology

[0002] With the rapid development of new energy sources and large-scale electricity substitution, overhead cables are everywhere on the ground. On the other hand, with the technological development of drones and other low-altitude aircraft, the scale of the low-altitude economy is constantly expanding. However, because the cables erected in the low-altitude area are too thin and have low visibility, drones have difficulty identifying such obstacles when automatically avoiding them. When the two appear in the same scene, they are prone to collision, causing personal injury and property damage risks.

[0003] To address the aforementioned issues and ensure power grid safety and the development of the low-altitude economy, it is necessary to improve the visibility of overhead cables and reduce accident risks. Installing aviation warning balls on the cables is one of the simplest ways to do this.

[0004] However, the existing aviation warning balls and their installation methods have the following drawbacks: the traditional installation methods for aviation warning balls are threaded connections and binding connections, both of which are carried out manually. It takes two people three hours to install one aviation warning ball, which poses a high safety risk, is labor-intensive, is difficult to accurately position, and the ball is too large to work on both sides, resulting in low production efficiency. At the same time, it is easy for the empty shell to jam the wire and damage the cable. Summary of the Invention

[0013] In some embodiments, the locking assembly includes a first locking seat, a second locking seat, a linear pawl, and a torsion spring. The first locking seat is connected to the first spherical shell, and the second locking seat is connected to the second spherical shell. The linear pawl and the torsion spring are disposed on the second locking seat, and a locking opening is formed on the first locking seat. The torsion spring is adapted to move the linear pawl along a direction perpendicular to the depth of the locking opening, so that the linear pawl engages with the locking opening after entering it. The second locking seat is provided with a detachable push-opening bolt. The push-opening bolt has an actuating end and an operating end. The actuating end of the push-opening bolt faces the first locking seat. When the operating end of the push-opening bolt is operated, the actuating end of the push-opening bolt is adapted to extend or retract from the second locking seat. When the actuating end of the push-opening bolt extends out of the second locking seat, it is adapted to restrict the linear pawl from entering the locking opening.

[0014] A self-installing aviation warning ball mounting system includes a mounting frame and any of the self-installing aviation warning balls described above. The mounting frame extends to both sides of the ball along the axial direction of the sleeve and has guide grooves. The openings of the guide grooves are adapted to the opening and closing sides of the ball. A support assembly is provided on the mounting frame. The support assembly includes a driver and two symmetrically arranged positioning support blades. The positioning support blades are hinged to the mounting frame. The driver and the positioning support blades are drivenly connected. The positioning support blades are adapted to be inserted into a wedge-shaped opening suitable for the ball to open. When the driver drives the positioning support blades to exit the wedge-shaped opening outward, the first and second ball shells are adapted to close to form the ball.

Then it continues to descend to wedge the wire into the sphere and sleeve along the guide groove. S600, the driver on the starting mounting bracket extends, pushing the two positioning support blades to the separation position. The positioning support blades leave the ball, and the ball automatically closes and locks under the action of the closing device, and the sleeve and wire are engaged for protection. The S700 aircraft returned to the ground carrying the mounting frame, completing the installation.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: 1. The self-installing aviation warning ball of this application has a first kit and a second kit that are linked to the first and second shells between the first and second shells. When the first and second shells are assembled into a ball, the first kit and the second kit can be engaged to form a sleeve, thereby compressing and wrapping the wire. This not only improves the connection stability between the warning ball and the wire, but also protects the wire and reduces the probability of the shell damaging the cable. The first and second shells can be engaged automatically and locked by a closing device to achieve a reliable connection and fixation between the warning ball and the wire. The first kit and the second kit are modular designs and can be replaced with different styles to adapt to different specifications of wires, increasing applicability.

[0019] 2. The self-installing aviation warning ball installation system of this application is designed with a special mounting frame to help the warning ball be installed automatically. The warning ball can be stably fixed on the mounting frame. The mounting frame and the wire are put together by means of aircraft such as drones, so that the warning ball can be stably and accurately installed on the wire. The whole process does not require manual operation, with low safety risk, accurate positioning and fast installation speed.

[0020] 3. The installation method of the self-installing aviation warning ball of this application can stably fix the warning ball on the mounting frame, allowing the warning ball to enter the pre-installation state, and then hoist it by the aircraft. The aircraft only needs to ensure that the mounting frame and the wire are accurately connected, and then release the warning ball. The warning ball can automatically close and lock, solving the pain point of manual high-altitude operation, realizing automatic installation, and the installation is more efficient.

[0037] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0039] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0040] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0041] The following description, in conjunction with the accompanying drawings, further illustrates this application: like Figures 1 to 15 As shown, this application provides a self-installing aviation warning ball, including a first spherical shell 11 and a second spherical shell 12, the first spherical shell 11 and the second spherical shell 12 are hinged to each other and adapted to be joined to form a sphere 1.

[0042] like Figures 2 to 4 In the embodiment shown, the first spherical shell 11 and the second spherical shell 12 are hemispherical shapes formed by molding. They have basically the same structure, which can reduce production costs and improve production efficiency. The first spherical shell 11 and the second spherical shell 12 can form a complete circle after being joined together. This design can make the weight of the first spherical shell 11 and the second spherical shell 12 similar, which can improve the balance during and after installation.

[0043] In some embodiments, after the first spherical shell 11 and the second spherical shell 12 are hinged together by a pin, the two ends of the pin are heat-sealed and riveted, so that the hinge between the first spherical shell 11 and the second spherical shell 12 cannot be disassembled and separated, which can improve the connection strength and assembly accuracy of the two.

[0044] like Figures 2 to 4As shown, a first assembly 21 is hinged to the mating side of the first spherical shell 11, and a second assembly 22 is hinged to the mating side of the second spherical shell 12. The first assembly 21 and the second assembly 22 are hinged to each other and adapted to mate to form a sleeve 2. The opening and closing side of the sleeve 2 is adapted to match the opening and closing side of the sphere 1. The sleeve 2 is adapted to receive the wire 3 entering from the opening and closing side of the sphere 1, that is, the opening and closing side of the sleeve 2 and the opening and closing side of the sphere 1 face the same side (see reference). Figure 2 , 3 With the opening and closing sides of the sphere 1 and sleeve 2 both facing downwards, the wire 3 can enter the sphere 1 and sleeve 2 in sequence, and then the sleeve 2 and sphere 1 close. This design can improve the smoothness of the sphere 1 and sleeve 2 in the process of cooperating with the wire 3 and reduce the probability of interference and collision between the wire 3 and the sphere 1.

[0045] It is understandable that, since the first kit 21 and the second kit 22 are used to fix the wire 3, and the sphere 1 can wrap the sleeve 2 formed by the first kit 21 and the second kit 22, the size of the first kit 21 and the second kit 22 is much smaller than the size of the sphere 1. In this application, the first spherical shell 11, the second spherical shell 12, the first kit 21 and the second kit 22 are all connected, so that the first kit 21 and the second kit 22 can limit and guide the movement of the first spherical shell 11 and the second spherical shell 12. When the first kit 21 and the second kit 22 are fully opened, the first spherical shell 11 and the second spherical shell 12 cannot continue to move away from each other, and there will be no reverse opening, which is beneficial to improving the stability of the warning ball installation process.

[0046] In some embodiments, the first kit 21 and the second kit 22 are made of flexible materials such as rubber. The sleeve 2 formed by the first kit 21 and the second kit 22 can fully wrap and protect the wire 3, isolate the contact between the ball 1 and the wire 3, and reduce contact wear and damage.

[0047] like Figures 2 to 4In the illustrated embodiment, the first spherical shell 11 and the second spherical shell 12 are joined to form an expansion channel 13. The sleeve 2 is disposed within the expansion channel 13. The first assembly 21 and the second assembly 22 are joined to form a clamping channel 23. The clamping channel 23 is exposed within the expansion channel 13, and the diameter of the expansion channel 13 is larger than the diameter of the clamping channel 23. It can be understood that the expansion channel 13 allows the wire 3 to pass through, while the clamping channel 23 is used to wrap and clamp the wire 3. This design can prevent the sphere 1 from contacting the wire within the clamping channel 23, reducing contact damage. Furthermore, by replacing different first assemblies 21 and second assemblies 22, the size of the clamping channel 23 formed by the joining can be changed to accommodate wires 3 of different thicknesses, thereby achieving high installation applicability. In practical applications, there is no need to adjust the size and structure of the first spherical shell 11 and the second spherical shell 12; only different specifications of the first assembly 21 and the second assembly 22 need to be selected. In this application, the first assembly 21 and the second assembly 22 are generally rubber sleeves, which are easier to manufacture and process and adjust in terms of structural dimensions. Therefore, production costs can be further reduced and production efficiency improved.

[0048] like Figures 2 to 4 In the embodiment shown, the first kit 21 and the second kit 22 are hinged along the length direction. The first kit 21 is aligned with the first spherical shell 11 along the length direction, and the second kit 22 is aligned with the second spherical shell 12 along the length direction. The clamping channel 23 is formed along the length direction of the sleeve 2.

[0049] When the opening / closing side of sphere 1 faces downwards, and the spherical shell and sleeve 2 close, the hinge axis between the first assembly 21 and the second assembly 22 is located above the wire clamping channel 23, and the hinge axis between the first assembly 21 and the first spherical shell 11, as well as the hinge axis between the second assembly 22 and the second spherical shell 12, is located below the wire clamping channel 23 (see reference). Figure 3 ).

[0050] like Figures 2 to 4 In the embodiment shown, the clamping channel 23 is the axis of the sleeve 2 and passes through the center of the ball 1. When the sleeve 2 is connected to the wire 3, the weight of the ball 1 around the sleeve 2 is more balanced, making the ball 1 more stable after installation and less prone to deflection. The rubber sleeve 2 and the wire 3 can also form a large friction force, which plays a stabilizing role.

[0051] like Figures 2 to 7As shown, a closing device 4 is provided on the opening and closing side of the sphere 1. The closing device 4 is adapted to be triggered when the first sphere shell 11 and the second sphere shell 12 approach and engage with each other. The closing device 4 is adapted to keep the first sphere shell 11 and the second sphere shell 12 closed. This application achieves the closing and locking required in the final step of the warning ball installation process by setting the closing device 4, ensuring the installation stability of the aviation warning ball. The closing device 4 can make the locking operation automatic, thereby completely eliminating manual operation and making the installation of the aviation warning ball safer and faster.

[0052] like Figures 2 to 5 In the embodiment shown, the closing device 4 includes a magnetic attraction component 41, which includes at least one first magnet 411 and at least one second magnet 412. The first magnet 411 and the second magnet 412 are respectively embedded on the mating surfaces of the first spherical shell 11 and the second spherical shell 12. When the first spherical shell 11 and the second spherical shell 12 are mated together, the first magnet 411 and the second magnet 412 are adapted to attract each other.

[0053] In some embodiments, the furthest attraction distance between the first magnet 411 and the second magnet 412 needs to be greater than the maximum distance between the first spherical shell 11 and the second spherical shell 12 at that location (see reference). Figure 2 The distance between the first magnet 411 and the second magnet 412 below the first spherical shell 11 and the second spherical shell 12 is determined by setting the first magnet 411 and the second magnet 412, combined with the design of the first kit 21 and the second kit 22 to restrict the first spherical shell 11 and the second spherical shell 12 from moving away from each other. This ensures that the first magnet 411 and the second magnet 412 can maintain an attractive state when the sphere 1 is opened. When the external restriction of the first spherical shell 11 and the second spherical shell 12 is released, the first spherical shell 11 and the second spherical shell 12 can automatically close and lock under the action of the first magnet 411 and the second magnet 412.

[0054] Furthermore, the furthest attraction distance for the first magnet 411 and the second magnet 412 to meet the minimum attraction requirement must be greater than the maximum distance between the first spherical shell 11 and the second spherical shell 12 at that location, to ensure that the first magnet 411 and the second magnet 412 can effectively drive the first spherical shell 11 and the second spherical shell 12 to close within this distance range.

[0055] In some embodiments, the first magnet 411 and the second magnet 412 are selected from N45 to N48 magnets to ensure that the attraction force of each is not less than 5kg, thereby reducing the probability of separation of the first spherical shell 11 and the second spherical shell 12.

[0056] like Figure 5In the illustrated embodiment, a first mounting opening 111 is provided on the first spherical shell 11, and a first magnet 411 is embedded in the first mounting opening 111. The top of the first magnet 411 is lower than the first mounting opening 111. A second mounting opening 121 is provided on the second spherical shell 12, and a second magnet 412 is embedded in the second mounting opening 121. The top of the second magnet 412 protrudes from the second mounting opening 121. When the first spherical shell 11 and the second spherical shell 12 are engaged with each other, the second magnet 412 is adapted to extend into the first mounting opening 111 and attract with the first magnet 411. This design enables the magnetic attraction between the first magnet 411 and the second magnet 412 to produce a guiding effect, ensuring the reliability and stability after engagement.

[0057] like Figure 5 In the embodiment shown, the opening of the first mounting port 111 is flared outward in the shape of a trumpet. The purpose of this is to avoid structural interference and collision between the top edge of the second magnet 412 and the first mounting port 111, and to protect the first magnet 411 and the second magnet 412 from damage.

[0058] like Figure 5 In the embodiment shown, the inner diameter of the first mounting port 111 is larger than the outer diameter of the first magnet 411. The gap between the first mounting port 111 and the first magnet 411 is filled with a lubricating medium 14. The lubricating medium 14 can play a guiding and buffering role, further protecting the first magnet 411 and the second magnet 412 from damage.

[0059] In some embodiments, the lubricating medium 14 is grease.

[0060] like Figure 5 In the embodiment shown, the first magnet 411 is connected to the first mounting port 111 by a fastener passing through its outer side, and the second magnet 412 is connected to the second mounting port 121 by a fastener passing through its outer side. The outer end of the fastener is lower than the surface of the first magnet 411 and the second magnet 412, so that the surface of the first magnet 411 and the second magnet 412 does not have protrusions, thus avoiding the first magnet 411 and the second magnet 412 from attracting each other and colliding and breaking.

[0061] In some embodiments, the fastener is a stainless steel screw, which is installed by rotating and tightening with a snap ring pliers. Its head thickness is less than 0.5 mm, and the decrease in attraction force on the first magnet 411 and the second magnet 412 does not exceed 5%. The surface is flat and without gaps.

[0062] In some embodiments, the first magnet 411 and the second magnet 412 use magnets of the same specification. A galvanized pad is provided at the second magnet 412. The galvanized pad is located between the second magnet 412 and the second spherical shell 12 to compensate for the installation space, so that the second magnet 412 can protrude from the second mounting opening 121, thereby increasing the versatility of the components and reducing procurement and production costs.

[0063] like Figure 4 In the embodiment shown, there are multiple first magnets 411 and second magnets 412. The first magnets 411 are evenly distributed close to the opening and closing side of the sphere 1, which can increase the attraction of the sphere 1 at the opening and closing side and reduce the probability of the sphere 1 opening.

[0064] like Figures 2 to 5 In the illustrated embodiment, a push-opening device 5 is provided on the opening and closing side of the sphere 1. The push-opening device 5 includes a push-opening bolt 51, which is detachably mounted on the first spherical shell 11. The push-opening bolt 51 has an actuating end 511 and an operating end 512. The actuating end 511 of the push-opening bolt 51 faces the second spherical shell 12. When the operating end 512 of the push-opening bolt 51 is operated, the actuating end 511 of the push-opening bolt 51 is adapted to extend or retract to the mating side of the first spherical shell 11. When the actuating end 511 of the push-opening bolt 51 extends to the mating side of the first spherical shell 11, it is adapted to restrict the mating of the first spherical shell 11 and the second spherical shell 12. Considering that the suction force when the first spherical shell 11 and the second spherical shell 12 are attracted together is strong, and the surface of the sphere 1 formed after closing is smooth, it is difficult to open stably by human power. Therefore, the push-opening device 5 is provided to realize the opening operation of the first spherical shell 11 and the second spherical shell 12. The push-opening device 5 can open a gap in the sphere 1, and then the sphere 1 can be opened through this gap.

[0065] In some embodiments, the jacking bolt 51 and the first spherical shell 11 are threadedly connected. By rotating the operating end 512 of the jacking bolt 51, the jacking bolt 51 can be moved relative to the first spherical shell 11, so that the operating end 511 can extend or retract to the mating side of the first spherical shell 11, making the operation convenient and effortless.

[0066] like Figure 4 , 6 In the embodiments shown in 7, the closing device 4 includes a backstop mechanism 6, which includes a locking component 61 and a locking port 62. The locking component 61 and the locking port 62 are respectively disposed on the first spherical shell 11 and the second spherical shell 12. When the first spherical shell 11 and the second spherical shell 12 are engaged, the locking component 61 is adapted to engage with the locking port 62 to restrict the first spherical shell 11 and the second spherical shell 12 from moving away from each other.

[0067] Specifically, the locking assembly 61 includes a first locking seat 611, a second locking seat 612, a linear pawl 613, and a torsion spring 614. The first locking seat 611 is connected to the first spherical shell 11, and the second locking seat 612 is connected to the second spherical shell 12. One end of the linear pawl 613 is rotatably connected to the second locking seat 612 and is provided with a torsion spring 614. The locking port 62 is opened on the first locking seat 611. The torsion spring 614 is adaptable to deformation, so that the pawl at the other end of the linear pawl 613 moves in a direction perpendicular to the depth of the locking port 62, so that the linear pawl 613 can engage with the locking port 62 after entering the locking port 62. When the first spherical shell 11 and the second spherical shell 12 are engaged, the backstop mechanism 6 can achieve a mechanical fixed connection, preventing the magnetism of the attracting magnet from being demagnetized under the influence of the magnetic field environment of the ground wire and the high temperature environment, thus ensuring that the first spherical shell 11 and the second spherical shell 12 will not open automatically and fall off.

[0068] Furthermore, the jacking bolt 51 can be detachably mounted on the second locking seat 612 (see reference). Figure 5 The operating end 511 of the jacking bolt 51 faces the first locking seat 611. When the operating end 512 of the jacking bolt 51 is operated, the operating end 511 of the jacking bolt 51 is adapted to extend or retract the second locking seat 612. When the operating end 511 of the jacking bolt 51 extends out of the second locking seat 612, it is adapted to restrict the linear pawl 613 from entering the locking port 62. The jacking bolt 51 is integrated into the locking assembly 61. When the jacking bolt 51 extends, it can simultaneously restrict the magnetic suction assembly 41 and the locking assembly 61 from automatically closing and locking the ball 1, so that the ball 1 remains open, which facilitates the preliminary installation preparation.

[0069] It is worth noting that the first spherical shell 11 and the second spherical shell 12 are a double-hinged movable assembly. The overall movable assembly is achieved by the self-hinged fit between the first spherical shell 11 and the second spherical shell 12 and the transitional hinge between the first kit 21 and the second kit 22. The closure of the first spherical shell 11 and the second spherical shell 12 is achieved by magnetic attraction. If the attraction of the first spherical shell 11 and the second spherical shell 12 is not controlled and orderly disengaged, the two hemispheres will not be able to be installed after being magnetically attracted. Therefore, the warning ball of this application needs to be assembled in the following way, and it must be strictly implemented in the production assembly process.

[0070] Step 1: Connect the first spherical shell 11 and the second spherical shell 12 with a hot-riveting hinge pin, and then install the opening bolt 51 to close and check the two hemispheres. Check for misalignment, burrs or dimensional errors. If any are found, correct them. If not, heat-lock the hot-riveting hinge pin.

[0071] Step 2: Separate and lay the first spherical shell 11 and the second spherical shell 12 flat. Temporarily connect the first assembly 21 and the second assembly 22 with the hinge holes of the corresponding first spherical shell 11 and the second spherical shell 12 using hinge pins. Then, check the closure of the two hemispheres, correct any errors, and ensure good closure. Next, assemble the linear pawl 613, pawl pin, and torsion spring 614 of the backstop mechanism 6, close the two hemispheres, and check whether the linear pawl 613 can smoothly engage. If there are any movement obstacles, repair them.

[0072] Step 3: Assemble the second magnet 412 into the mounting position of the second spherical shell 12, then align the two hemispheres and check whether the closure and the insertion of the second magnet 412 into the first mounting port 111 are smooth and without jamming. After eliminating the relevant problems, rotate the opening bolt 51 to the bottom to ensure that the two hemispheres can no longer close, so as to assemble the first magnet 411.

[0073] Step 4: Assemble the first magnet 411, then align the hinge positions of the first kit 21 and the second kit 22, put on the rubber sleeve hinge pin, and complete the overall assembly. In order to facilitate transportation, the two hemispheres need to be tied tightly with cable ties at the opening bolt 51 (reverse stop mechanism 6) position. They will be untied when they arrive at the installation site to ensure stability during transportation.

[0074] like Figures 8 to 11 As shown, this application also provides an installation system for a self-installing aviation warning ball, including a mounting frame 7 and a self-installing aviation warning ball according to any of the above embodiments. The mounting frame 7 extends to both sides of the ball 1 along the axial direction of the sleeve 2 and has a guide groove 711. The opening of the guide groove 711 is adapted to the opening and closing side of the ball 1. The mounting frame 7 can be docked and positioned with the wire 3 through the guide groove 711, and the wire 3 can slide along the guide groove 711 and enter from the opening and closing side of the ball 1, thereby making the installation process smoother and faster.

[0075] The width of the guide groove 711 can be set to be slightly larger than the diameter of the wire 3. The guide groove 711 can directly guide the wire 3 to the limit position where it engages with the first kit 21 and the second kit 22. At the same time, it can isolate the magnetic attraction of the first magnet 411 and the second magnet 412 on the wire 3, ensuring that the wire 3 smoothly wedges into the sphere 1.

[0076] like Figure 8 and 9In the illustrated embodiment, a support assembly 72 is provided on the mounting frame 7. The support assembly 72 includes a driver 721 and two symmetrically arranged positioning support blades 722, which ensures that the center of gravity of the mounting frame 7 and the ball 1 is centered after installation and connection, thereby improving stability. The positioning support blades 722 are hinged to the mounting frame 7. The driver 721 and the positioning support blades 722 are driven to connect. The positioning support blades 722 are adapted to be inserted into the wedge opening suitable for the opening of the ball 1. When the driver 721 drives the positioning support blades 722 to exit the wedge opening, the first ball shell 11 and the second ball shell 12 are adapted to close to form the ball 1. The action planes of the two positioning support blades 722 are located on the same plane. The double-blade design can achieve stable support for the entire warning ball. The wedge opening of the ball 1 is located on both sides of the plane where the double blades are located. The entire ball 1 remains stable and does not deflect under the action of the positioning support blades 722.

[0077] Considering the need for live-line installation, all large components on this mounting bracket 7, except for the electric push rod, are made of insulating material, so all connections are made using threaded connections.

[0078] like Figure 8 and 9 In the embodiment shown, the positioning support blade 722 has cutting edges 7221 on both sides. When the positioning support blade 722 enters the wedge, the cutting edges 7221 are adapted to contact the ball 1 first. When the positioning support blade 722 exits the wedge, the cutting edges 7221 are adapted to detach from the ball 1 last, so that the positioning support blade 722 can completely exit from the ball 1 held and engaged by the strong magnetic force. During the exit process, it is adapted to gradually release the attraction gap of the ball 1, so as to avoid the first ball shell 11 and the second ball shell 12 being impacted by the strong magnetic force due to the sudden exit of the positioning support blade 722, which would cause damage to the equipment.

[0079] like Figure 8 and 9 In the embodiment shown, the mounting frame 7 has a hanging beam 73, and the hanging beam 73 is provided with at least one connection point 731 for hoisting.

[0080] like Figure 8 and 9 In the embodiment shown, there are at least two connection points 731. The mounting frame 7 and the warning ball are connected to the connection points 731 by two connecting cables for hoisting. This can improve the stability of the hoisting process, prevent the mounting frame 7 from deflecting, and reduce the difficulty of accurately docking with the wire 3.

[0081] like Figure 8 and 9In the embodiment shown, the mounting frame 7 is provided with a positioning groove 732 that matches the hinge position of the first spherical shell 11 and the second spherical shell 12. The positioning groove 732 can position the sphere 1. With the help of the positioning support blade 722, the wedge opening of the sphere 1 and the guide grooves 711 on both sides are in the same vertical plane, ensuring accurate positioning at high altitude. Specifically, the positioning groove 732 can be opened on the hanging beam 73.

[0082] like Figure 8 and 11 In the embodiment shown, the opening of the guide groove 711 has an outward expansion structure, which makes it easier for the mounting bracket 7 to connect with the wire 3, reducing the difficulty of operation and improving the efficiency of operation.

[0083] like Figure 8 and 9 In the embodiment shown, guide plates 71 are provided on both sides of the hanging beam 73, guide grooves 711 are opened on the guide plates 71, and counterweight mounting holes 712 are opened on the guide plates 71 for installing counterweight blocks to balance the weight on the left and right sides of the assembly formed by the mounting frame 7 and the warning ball.

[0084] like Figure 8 and 9 In the embodiment shown, a reinforcing plate 74 is connected between the hanging beam 73 and the guide plate 71 to strengthen the overall strength of the mounting frame 7 and ensure that it has sufficient load-bearing capacity.

[0085] like Figures 10 to 15 As shown, this application also provides a method for installing a self-installing aviation warning ball, the installation process of which requires the following steps: S100, the actuator 721 on the starting mounting bracket 7 extends, pushing the two positioning support blades 722 to the separated position, as shown in the reference. Figure 9 Mounting bracket 7 is in the middle; S200, operate the opening device 5 to open the opening side of the ball 1 and form a wedge, push the hinged position of the ball 1 upward into the positioning groove 732 of the mounting bracket 7, as shown in the reference. Figure 8 Mounting bracket 7 is in the middle; S300, activate the retraction of the driver 721 on the mounting bracket 7, inserting the two positioning support blades 722 into the open wedge of the ball 1 until the wedge can open to its maximum position. Remove the push-opening bolt 51 to ensure that the warning ball can automatically close after being released. Refer to [reference needed]. Figure 1 The combined state of the mounting bracket 7 and the warning ball; S400, control the aircraft 8 to fly above the mounting frame 7, and connect the connecting cable to the connection point 731 of the mounting frame 7. (Refer to...) Figure 10 and Figure 11 Schematic diagram of the connection between the aircraft 8 and the mounting frame 7; S500: The aircraft 8 flies over the ground wire 3 and straddles it, aligning the opening of the guide groove 711 with the wire 3. It slowly descends, wedging the wire 3 into the guide groove 711. The drone monitors the wire 3 via video surveillance until it reaches the engagement position with the first assembly 21 and the second assembly 22 of the warning ball and bears weight (this can be confirmed by observing the deformation of the wire 3). Then, the remote-controlled electric push rod extends the positioning support blade 722, and the aircraft continues to descend, wedging the wire 3 along the guide groove 711 into the ball 1 and the sleeve 2. (Refer to...) Figure 12 and 13 A schematic diagram of the interaction between the warning ball and wire 3; S600, the actuator 721 on the starting mounting bracket 7 extends, pushing the two positioning support blades 722 to the separated position. The positioning support blades 722 leave the ball 1, and the ball 1 automatically closes and locks under the action of the closing device 4. The sleeve 2 and the wire 3 are engaged for protection. (Refer to...) Figure 13 and 14 A schematic diagram of the interaction between the warning ball and wire 3; In this application, a total of 25 pairs of first magnets 411 and second magnets 412 are provided (see reference). Figure 4 Each pair of attraction forces is 8kg, the magnetic attraction force is 200kg, and the rubber sleeve generated at the center of the warning ball has a gripping force of 400kg on the wire 3. This force is a foolproof and reliable fixation for the aviation warning ball, which weighs less than 10kg. While the magnetic force is locking, the linear pawl 613 of the reverse stop mechanism 6 reaches the locking position with the movement of the first ball shell 11 and the second ball shell 12, locking the two hemispheres together.

[0086] After the S700 sphere 1 is installed, the mounting bracket 7 automatically detaches from the sphere 1, and the aircraft 8 carries the mounting bracket 7 back to the ground, completing the installation process of a warning sphere.

[0087] In this application, the aircraft 8 preferably uses a drone, which can perform remote control operations and is safer.
