Description

Technical Field

[0001] The invention relates to the technical field of aviation fire fighting, and in particular to a bracket device and a method for mounting fire extinguishing bombs on a general aircraft. Background Art

[0002] In the field of aviation firefighting, general-purpose aircraft play an increasingly important role in firefighting operations due to their flexibility and rapid response capabilities. Traditional firefighting methods, such as using large aircraft to pump water to extinguish fires, are effective, but their efficiency and safety are limited when facing complex terrain or difficult-to-access fires. Therefore, general-purpose aircraft carrying fire-extinguishing bombs has become an effective supplementary means. However, the existing mounting system has some shortcomings, which are reflected in patents CN107891891A and CN203793375U.

[0003] Patent CN107891891A describes a short-distance transport vehicle for fire extinguishers, which is mainly used for transporting fire extinguishers on the ground rather than mounting fire extinguishing bombs in the air. It realizes the short-distance transportation and shaking of fire extinguishers through the design of the moving device and the placing device, so that the operator can directly use the fire extinguisher when taking it out. Although the patent provides a time-saving and labor-saving transportation method, it does not involve the automation and intelligent requirements of mounting fire extinguishing bombs in the air.

[0004] On the other hand, patent CN203793375U discloses a fire extinguishing bomb transport device, which includes a multi-layer structure for transporting fire extinguishing bombs efficiently, at low cost and with high safety. It provides protection for the fire extinguishing bomb by arranging a sponge layer and a coolant layer in the fire extinguishing bomb storage cylinder. However, the device mainly focuses on the storage and transportation of fire extinguishing bombs, rather than the mounting process on general aircraft.

[0005] In the existing general aircraft mounting fire bomb operations, it usually relies on simple mechanical devices or purely manual operations, which have many limitations. For example, low operating efficiency, poor safety, and high operator skill requirements. Especially in emergency situations, quickly and effectively mounting fire bombs on aircraft is crucial for timely response to fire scenes. However, existing mounting systems often cannot meet the needs of rapid response and there are safety hazards in actual operation.

[0006] In addition, the fuselage of general aircraft is low to the ground, and the operating space is limited when mounting fire bombs, which makes manual mounting difficult and time-consuming. Manual operation is difficult to ensure the accuracy and consistency of mounting, which increases the risk during the operation. In some cases, such as forest fires, the complexity and unpredictability of the fire scene require that firefighting operations can be carried out quickly and accurately. Existing mounting systems usually lack intelligent and automated features, and cannot adapt to changing operating environments and improve operating efficiency.

[0007] Therefore, there is an urgent need for a bracket device and method for mounting fire extinguishing bombs on general aircraft. Summary of the invention

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0049] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0050] Example 1

[0051] like Figure 1As shown, a bracket device for mounting fire extinguishing bombs on general aircraft includes a chassis 2, a telescopic part, a support plate 9 and a control module; the chassis 2 is a solid chassis 2 structure, and the bottom is equipped with one or more moving wheels 5, and the moving wheels 5 enable the chassis 2 to be easily moved on the airport runway or other hard ground, so as to position the bracket device to a suitable position under the aircraft; the telescopic part is a mechanical telescopic mechanism, one end of which is fixedly connected to the chassis 2, and the other end is connected to a table 8, and the telescopic part is designed for telescopic movement in the vertical direction to adjust the height of the table 8 so that it can adapt to the height of the fuselage of general aircraft of different models from the ground , ensuring that the fire extinguishing bomb can be mounted smoothly; the support plate 9 is a flat plate 9 structure or a support plate 9 structure with a fine adjustment angle, which is arranged on the table 8 and is used to carry the fire extinguishing bomb. The size and shape design of the support plate 9 can match the bottom contour of the fire extinguishing bomb to ensure that the fire extinguishing bomb is stably placed during the mounting process to prevent sliding or accidental falling off; the control module is an integrated control unit, which is connected to the telescopic part and is used to control the lifting and lowering action of the table 8. The control module can be manually operated or automatically controlled. According to the operator's choice or preset program, the movement of the telescopic part is accurately controlled to ensure that the table 8 can smoothly and safely lift the fire extinguishing bomb to the aircraft mounting position.

[0052] Specifically, the chassis 2 can be made of high-strength steel or aluminum alloy to ensure durability and stability in the process of bearing the weight of the fire extinguishing bomb and operation. The moving wheel 5 can be a solid rubber wheel to provide good ground grip and reduce vibration during movement. The telescopic part can use a hydraulic or pneumatic cylinder as a driving force, and the operation instructions received by the control module are used to achieve the precise lifting of the table 8. The table 8 can be designed to be retractable to adapt to fire extinguishing bombs of different sizes to ensure that there is enough support area during the lifting process. The support plate 9 can be made of heat-resistant and corrosion-resistant materials, and the surface can be designed with anti-skid textures or grooves to increase the friction with the fire extinguishing bomb to prevent sliding during the lifting process. A limit device can also be set on the support plate 9 to ensure that the fire extinguishing bomb remains in the correct position during the lifting process. The control module can include an operating panel with buttons or switches on it for manually controlling the lifting of the table 8. In addition, the control module can also integrate sensors and actuators to achieve automatic control, such as detecting the load on the table 8 through a pressure sensor to automatically adjust the lifting speed and height.

[0053] When mounting a fire extinguishing bomb, the operator first moves the bracket device to the bottom of the aircraft, adjusts the height of the table 8 through the control module, and raises the pallet 9 to a position aligned with the aircraft mounting point. Then, the fire extinguishing bomb is placed on the pallet 9 and fixed using the limit device on the pallet 9. After confirming that the fire extinguishing bomb is stably placed, the operator issues a lifting command through the control module to lift the table 8 and the fire extinguishing bomb to the aircraft mounting position. Under the operation of the aircraft mounting personnel, the fire extinguishing bomb is connected to the aircraft mounting system to complete the mounting process. Finally, the control module lowers the table 8, and the bracket device moves out of the working area to prepare for the next mounting operation.

[0054] The bracket device can realize rapid, safe and accurate mounting of the fire extinguishing bomb on the general aircraft, thereby improving the efficiency and safety of the fire extinguishing operation.

[0055] Example 2

[0056] The present application may also include a hand pusher 1, which may be disposed on a chassis 2, and a person may push the chassis 2 to move. The chassis 2 may be made of a sturdy steel structure or an aluminum alloy frame to withstand the weight of the fire extinguishing bomb and the stress during operation. The hand pusher 1 may be designed as an ergonomic handle, which may be T-shaped or D-shaped, so that the operator can hold and apply force. The handle surface may be covered with an anti-slip material, such as rubber, to increase the stability of the grip.

[0057] The push part 1 is fixed to the chassis 2 at an appropriate position by welding or bolts to ensure stability and durability during pushing. The connection can be designed with a buffer material to absorb the impact during pushing. The position and design of the push part 1 allow the operator to easily push the bracket device from one side without having to operate around the device, which can reduce the operator's moving distance and improve operating efficiency.

[0058] In the design of the push part 1, quick disengagement in an emergency situation is taken into consideration. For example, a quick release mechanism can be provided so that the operator can quickly disengage the handle in an emergency situation to avoid accidental injury.

[0059] The push part 1 not only provides a simple moving method, but also increases the safety and stability of the operation, so that the bracket device can be used more efficiently and safely in the operation of mounting fire extinguishing bombs on general aircraft. The actual operation requirements are fully considered to ensure the practicality and reliability of the bracket device.

[0060] like Figure 1As shown, as a specific example, the present invention is composed of nine parts: a hand push part 1, a chassis 2, a release rod 3, a pedal rod 4, a universal wheel, an oil pump transmission 6, a telescopic rod 7, a table 8, and a support plate 9. The handle is welded to the chassis 2 for moving the entire device. The chassis 2 is connected to the universal wheel for supporting and fixing each part, and the direction is adjusted by the universal wheel. The table 8 is connected to the telescopic rod 7 so that the device can move up and down to meet the height requirements. The telescopic rod 7 is connected to the oil pump transmission 6 so that it can raise and lower the table 8, wherein the combination of the release rod 3, the pedal rod 4 and the oil pump transmission 6 is a control module. The support plate 9 is connected to the table 8 by bolts, and the rise and fall of the support plate 9 is driven by the travel of the table 8. The release rod 3 and the pedal rod 4 are connected to the oil pump transmission 6, and the release rod 3 is sprayed with red paint to distinguish it from the pedal rod 4.

[0061] By using this device, the space utilization and work efficiency of ground staff in the lower part of the aircraft fuselage can be effectively improved, and the safety of staff can be guaranteed. It has great application value.

[0062] like Figure 1 As shown, the push part 1 is welded on the chassis 2; the chassis 2 moves through four universal wheels, driving the entire device to move; the foot pedal is stepped down to drive the lifting rod to rise through the oil pump transmission 6; the oil pump transmission 6 is installed on the chassis 2 and connected to the lifting rod; the release rod 3 can be stepped on to lower the lifting rod according to the height requirement, and the table 8 will drop accordingly; the movement of the lifting rod drives the table 8 to rise and fall; the support plate 9 follows the rise and fall of the table 8.

[0063] When using the device, after placing the fire extinguishing bomb on the support plate 9, pull the hand push part 1 to move it to the lower part of the fuselage, step on the pedal rod 4 to move through the oil pump transmission 6, drive the lifting rod to rise, and the table 8 rises accordingly. After the support plate 9 is moved to a suitable position, mount the fire extinguishing bomb on the suspension device, and then step on the release rod 3 to make the oil pump transmission 6 drive the lifting rod to retract, and the table 8 descends accordingly. After it is completely descended, the entire device is moved out of the working position by pulling the hand push part 1.

[0064] Example 3

[0065] The chassis 2 can also be provided with a power module for driving and a direction adjustment module for direction adjustment, and the movement of the device can be controlled by the control module. The power module on the chassis 2 can include one or more motors, which drive the moving wheels 5 on the chassis 2 through gears and chains, so that the bracket device can automatically move to a specified position. The power and speed of the motor can be selected and adjusted according to the weight and moving speed requirements of the bracket device. The direction adjustment module can include a steering system that allows the moving wheels 5 on the chassis 2 to turn in a predetermined direction. The steering system can be hydraulic or electronically controlled to achieve accurate direction adjustment and positioning. The power module and the direction adjustment module are connected to the control module via cables or wireless signals. The control module can be a centralized control panel, and the operator can input instructions through the panel to control the work of the power module and the direction adjustment module.

[0066] The control module has built-in control strategies to coordinate the actions of the power module and the direction adjustment module. For example, when the bracket device needs to move under the aircraft, the control module will issue a command to start the power module and adjust the direction adjustment module to move the bracket device smoothly to the predetermined position. To ensure the safety of operation, the power module and the direction adjustment module can be equipped with sensors and limit switches to prevent the bracket device from moving to unsafe areas or colliding.

[0067] The control module can be equipped with a user-friendly interface that displays the current status and position information of the carriage unit, as well as providing the option of manual operation to intervene if problems arise with the automatic control.

[0068] The bracket device can automatically move to the bottom of the aircraft and accurately adjust its direction to facilitate the mounting of fire extinguishing bombs. This automated and precisely controlled design improves the efficiency and safety of the mounting operation while also reducing the workload of operators.

[0069] Example 4

[0070] The present application also includes an intelligent identification and positioning system. The system consists of multiple modules, each of which has a specific function, which together realizes the accurate identification and positioning of the fire extinguishing bomb so that it can be accurately mounted on the aircraft. Specifically, this system includes: an image acquisition module: used to capture the visual image of the lower part of the aircraft fuselage and the fire extinguishing bomb. The image preprocessing module performs preliminary processing on the collected images, such as noise reduction, enhancement and binarization, to improve the image quality. The image analysis module uses a deep learning algorithm to analyze the image and identify the model and position of the fire extinguishing bomb. The pallet positioning module calculates the spatial coordinates and attitude angle of the fire extinguishing bomb based on the image analysis results, and provides accurate position information for mounting. The control center receives the data of the pallet positioning module, controls the movement and lifting of the bracket device, and ensures that the pallet 9 is adjusted to a suitable mounting position. The database stores the reference image of the fire extinguishing bomb, the pallet point cloud model and the spatial data of the lower part of the aircraft fuselage for auxiliary identification and positioning.

[0071] The image acquisition module uses a high-resolution industrial camera equipped with autofocus and auto-exposure functions, mounted on a stable bracket of a bracket device to ensure clear images under different environmental conditions.

[0072] The image preprocessing module is implemented as a software algorithm running on the computing platform of the control center. The algorithm includes filters to remove image noise, enhancement algorithms to improve image contrast, and binarization processing to convert the image into a clear black and white image.

[0073] The image analysis module is based on deep learning image recognition models, such as convolutional neural networks (CNN), which are well trained to identify different types of fire extinguisher bombs and determine their exact locations in the image. The module can process image data in real time and output the location and posture information of the fire extinguisher bombs.

[0074] The pallet positioning module is a calculation unit that receives the output of the image analysis module and calculates the specific parameters that need to be adjusted for the pallet 9 in combination with the current position of the bracket device. The module can update the position data in real time to adapt to changes in the position of the aircraft.

[0075] The control center is an integrated computer system that receives data from the pallet positioning module and generates control signals based on these data. These signals are transmitted to the power module and direction adjustment module of the bracket device through electrical connection to control the precise movement and positioning of the pallet 9.

[0076] The database is a storage system that contains reference images of fire extinguishing bombs, point cloud models of the pallet 9, and spatial data of the lower part of the aircraft fuselage. The database can be accessed and updated by the control center to ensure the accuracy of identification and positioning.

[0077] During the implementation process, the operator first moves the bracket device to the bottom of the aircraft and starts the image acquisition module to capture images. The control center automatically performs image preprocessing and analysis, and then issues instructions through the control center based on the analysis results to adjust the position and posture of the bracket 9 to match the aircraft's mounting point. Once the bracket 9 is positioned, the fire bomb can be safely and accurately mounted on the aircraft.

[0078] Example 5

[0079] The present application's pallet 9 part is one of the core components of the entire mounting system. The pallet 9 is designed to carry and fix the fire extinguishing bomb to ensure its stability and safety during mounting and transportation. It includes the following key features: the first pallet and the second pallet: the two pallets 9 are used to fix the two ends of the fire extinguishing bomb respectively to ensure that the fire extinguishing bomb will not move or fall off during the mounting process. The adjustment mechanism connects the first pallet and the second pallet, allowing the operator to adjust the front and rear tilt angles of the fire extinguishing bomb as needed to adapt to different mounting requirements or aircraft models. The locking mechanism is used to stabilize the fire extinguishing bomb during the mounting process to prevent it from moving due to vibration or impact during transportation or flight. When installing the fire extinguishing bomb, the mechanism can be unlocked to facilitate the fixing of the fire extinguishing bomb to the pallet 9. The rotating mechanism is arranged at the bottom of the first pallet and the second pallet, allowing the direction of the fire extinguishing bomb to be adjusted to ensure that it is accurately docked with the aircraft mounting system. Together, they constitute an efficient, flexible and safe pallet 9 system for supporting the mounting and positioning of the fire extinguishing bomb.

[0080] Specifically, the first support plate and the second support plate are made of high-strength aluminum alloy material to reduce weight while ensuring sufficient strength and durability. The support plate 9 is designed with grooves and fixing holes matching the fire extinguishing bomb, which are used to fix the fire extinguishing bomb on the support plate 9 by bolts or other fasteners.

[0081] The adjustment mechanism can adopt an electric or manual screw adjustment mechanism so that the first and second pallets can rotate relative to each other within a certain angle range to adjust the tilt angle of the fire extinguishing bomb. The mechanism can be equipped with a scale indicator so that it can be accurately adjusted to the desired angle. The locking mechanism can be designed as an automatic locking pin. When the pallet 9 is adjusted to the appropriate position, the position of the pallet 9 is locked by a simple operation (such as pressing a button or flipping a switch). When unlocking is required, the locking pin is released by a simple operation. The rotation mechanism can be designed as a rotating base so that the pallet 9 can rotate around the vertical axis. The mechanism can be controlled by a stepper motor to achieve precise angle adjustment. The operation of all mechanisms can be controlled by a centralized control module, which can be a handheld remote control or a control panel fixed to the bracket device. The control module is connected to each mechanism via a cable or a wireless signal. In order to ensure the safety of operation, the locking mechanism and the rotation mechanism on the pallet 9 are equipped with safety switches and limit sensors to prevent accidental unlocking or excessive rotation.

[0082] The bracket device can accurately adjust the position and direction of the fire extinguisher bomb to ensure that the fire extinguisher bomb can be safely and accurately mounted on the general aircraft. This design improves the efficiency and safety of the mounting operation and also reduces the workload of the operator.

[0083] Specifically, the first support plate and the second support plate are provided with mounting grooves, and the mounting grooves are provided with a diameter adjustment mechanism for adjusting the opening diameter of the mounting grooves and clamping the fire extinguishing bombs. The mounting grooves on the first support plate and the second support plate are designed to be semicircular, and their diameters are adapted according to the maximum diameter of the fire extinguishing bombs to ensure that the fire extinguishing bombs can be firmly placed on the support plate 9. The semicircular design of the mounting groove helps to improve the structural stability of the support plate 9 and reduce the use of materials. It also includes a diameter adjustment mechanism using a group of retractable clamps, which are arranged along the edge of the mounting groove and can be adjusted electrically or manually. The design of the clamps allows them to move in the semicircular mounting groove to accommodate fire extinguishing bombs of different diameters.

[0084] When the fire extinguishing bomb is placed on the support plate 9, the clamping claws will automatically adjust their positions according to the diameter of the fire extinguishing bomb by operating the diameter adjustment mechanism, thereby clamping the fire extinguishing bomb to prevent it from rolling or falling off during transportation or mounting.

[0085] The diameter adjustment mechanism can be controlled through a user interface integrated in the control module, through which the operator can select the required clamping force and position to achieve precise control of the diameter adjustment mechanism.

[0086] To ensure safe operation, the diameter adjustment mechanism is equipped with limit switches and pressure sensors to prevent over-clamping or accidental loosening.

[0087] The bracket device can realize the rapid, accurate and safe mounting of the fire extinguishing bomb, improves the efficiency and safety of the mounting operation, and also reduces the workload of the operator.

[0088] Example 6

[0089] It also includes an angle adjustment mechanism, which can be designed as a precise mechanical structure for adjusting the axial angle of the fire extinguishing bomb on the first support plate and the second support plate.

[0090] The angle adjustment mechanism is mainly composed of a central rotating shaft, a gear system, a drive motor and a control system. The central rotating shaft is vertically fixed between the first support plate and the second support plate, allowing the fire extinguishing bomb to rotate around the shaft. The gear system includes a driving gear and at least one driven gear. The driving gear is connected to the driving motor, and the driven gear is connected to the central rotating shaft. When the driving gear rotates, the driven gear is driven by the gear meshing transmission to rotate the central rotating shaft, thereby realizing the axial rotation of the fire extinguishing bomb. The driving motor can be a servo motor or a stepper motor, which can provide precise control and feedback to ensure that the rotation angle of the fire extinguishing bomb can be accurately adjusted and repeatedly positioned. The control system includes a control unit and a user operation interface. The control unit receives the instructions input by the user and controls the rotation of the drive motor according to the instructions to achieve angle adjustment. The user operation interface can be a touch screen or a physical button for inputting the rotation angle or selecting a preset angle.

[0091] After the angle is adjusted to a predetermined position, the angle adjustment mechanism is equipped with a locking mechanism, such as a gear lock or a friction lock, to ensure that the fire extinguishing bomb remains stable during transportation and mounting to prevent deflection due to vibration or accidental operation.

[0092] The angle adjustment mechanism is equipped with a position feedback sensor, such as an encoder or a Hall effect sensor, to monitor the exact position and angle of the fire bomb in real time. This data can be fed back to the control system to ensure the accuracy of the adjustment.

[0093] To ensure operational safety, the angle adjustment mechanism is designed with an emergency stop function and an automatic locking mechanism when power or control signal is lost.

[0094] Through the above specific implementation, the angle adjustment mechanism can achieve accurate direction adjustment of the fire extinguishing bomb, ensuring that the fire extinguishing bomb can be safely and accurately mounted on a general aircraft. This design improves the efficiency and safety of the mounting operation, and also reduces the workload of the operator.

[0095] Example 7

[0096] The device may also include a mounting mechanism, which is arranged on the table 8 and is used to mount the fire extinguishing bomb on the aircraft. The mounting mechanism includes a series of mechanical components, such as a clamping device, a positioning device and a locking device, which work together to ensure that the fire extinguishing bomb can be accurately mounted on the aircraft's mounting point. The clamping device is designed to firmly grasp the fire extinguishing bomb and remain stable during the mounting process. A set of adjustable jaws may be included, which can be adjusted according to the size of the fire extinguishing bomb to ensure a tight and secure clamping. The positioning device is used to ensure that the fire extinguishing bomb is accurately aligned with the aircraft's mounting point. This may include a set of optical alignment systems or mechanical guides to guide the fire extinguishing bomb to the correct position.

[0097] Once the bomb is correctly positioned, a locking mechanism is activated to ensure that the bomb does not come loose during flight. This may include a mechanical locking pin or similar securing mechanism.

[0098] The operation of the installation mechanism can be carried out by a control module, which receives instructions from the operator and controls the movement of the installation mechanism. The control module can be manual or automatic, depending on the complexity of the operation and the required precision.

[0099] To ensure safe operation, the mounting mechanism is equipped with an emergency stop switch and limit sensors to prevent accidental movement or operating errors.

[0100] The bracket device can realize the rapid, accurate and safe mounting of the fire extinguishing bomb, improves the efficiency and safety of the mounting operation, and also reduces the workload of the operator.

[0101] Example 8

[0102] like Figure 2 As shown, a bracket method for mounting fire extinguishing bombs on a general aircraft includes the following steps:

[0103] First, make sure that the fire extinguishing bomb meets the mounting requirements, and check all parts of the bracket device, including the chassis 2, the telescopic part, the support plate 9, the control module, etc., to ensure that they function normally.

[0104] The operator pushes the chassis 2 through the push part 1, and moves the bracket device to a predetermined position at the lower part of the aircraft fuselage using the moving wheels 5 at the bottom of the chassis 2. In this step, the power module and the direction adjustment module of the chassis 2 can assist in achieving more accurate positioning.

[0105] At a predetermined position under the aircraft fuselage, the control module is operated to issue a command to the telescopic part to raise the table 8 to a height corresponding to the aircraft mounting point. This step ensures the docking accuracy between the bracket device and the aircraft mounting system.

[0106] After confirming that the table 8 has reached an appropriate height, the fire extinguishing bomb is placed on the support plate 9 for fixing. Using the mounting groove and diameter adjustment mechanism on the support plate 9, the opening diameter of the mounting groove is adjusted to fit the fire extinguishing bomb, and the fire extinguishing bomb is clamped to ensure its stability.

[0107] After confirming that the fire extinguisher bomb is correctly placed and fixed, the operator connects the fire extinguisher bomb to the aircraft's mounting system so that the fire extinguisher bomb is firmly installed on the aircraft.

[0108] After the fire bomb is installed, a final check is carried out to ensure that all connections and fixations are correct. After confirming that there are no safety hazards, the operator evacuates the bracket device and completes the entire mounting process.

[0109] The bracket method can ensure that the fire extinguishing bomb is mounted on the general aircraft safely and efficiently, while reducing the workload of the operators and improving the accuracy and safety of the mounting operation.

[0110] The process also includes the following steps: using a high-resolution camera mounted on a bracket device to collect image data of the lower fuselage of the aircraft and the fire extinguishing bomb to be mounted. The camera is equipped with autofocus and autoexposure functions to ensure clear images under different lighting and weather conditions.

[0111] The collected image data is processed by the image preprocessing module to improve the image quality. This step includes noise reduction, image contrast enhancement, and image conversion into a binary image to better identify the outline and features of the fire bomb.

[0112] The image analysis module uses a preset deep learning algorithm, such as a convolutional neural network (CNN), to analyze the pre-processed image. The algorithm is able to identify the model and location of the fire bomb and compare it with the reference image stored in the database to confirm the exact model of the fire bomb.

[0113] The pallet positioning module calculates the spatial coordinates and attitude angle of the fire extinguishing bomb according to the image analysis results. These data are used to guide the movement and lifting of the bracket device to ensure that the pallet 9 can accurately align with the mounting point of the aircraft.

[0114] The control module receives data from the pallet positioning module and controls the power module and the direction adjustment module to move the bracket device to a predetermined position at the lower part of the aircraft fuselage. This step can be achieved by manual operation or automatic control.

[0115] After the support plate 9 is positioned at the correct position, the operator places the fire extinguishing bomb on the support plate 9 and uses the diameter adjustment mechanism to clamp the fire extinguishing bomb to ensure that it is firmly fixed on the support plate 9.

[0116] The control center of the intelligent identification and positioning system receives data provided by the pallet positioning module and makes the final mounting confirmation. This step ensures that the fire extinguisher bomb is correctly installed in the mounting position of the aircraft and all safety measures are in place.

[0117] Once it is confirmed that the fire extinguisher bomb has been securely installed on the aircraft, the operator will remove the bracket device from under the aircraft, completing the entire mounting process.

[0118] The bracket method can ensure that the fire extinguishing bomb is mounted on the general aircraft safely and efficiently, while reducing the workload of the operators and improving the accuracy and safety of the mounting operation.

[0119] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
