[0032] Example 1

[0033] Referring to Figure x, which is the first embodiment of the present invention, a mobile fire extinguisher maintenance device is provided. This device includes a moving device for moving the entire device. The moving device includes a railcar 200 and a maintenance device 100. The moving device is disposed below the maintenance device 100, and the maintenance device 100 is controlled by a controller.

[0034] Specifically, the maintenance device 100 includes an appearance inspection module 101, a disassembly module 102, a cylinder inspection module 103, a filling module 104, an airtightness inspection module 105, and a transport component; the inspection module is used to inspect the fire extinguisher; the disassembly module 102 is used to disassemble the fire extinguisher; the cylinder inspection module 103 is used to detect the cylinder pressure of the fire extinguisher; the filling module 104 is used to fill the fire extinguisher with extinguishing agent and motive gas; the airtightness inspection module 105 is used to test the airtightness and air pressure of the fire extinguisher; and the transport component is used to transport the fire extinguisher.

[0035] Furthermore, the transport components include a clamping mechanism for holding the fire extinguisher, a transverse slide rail, a longitudinal slide rail 107, and a rotating disk 108; the transverse slide rail and the longitudinal slide rail 107 are used to move the fire extinguisher, and both the transverse slide rail and the longitudinal slide rail 107 include an inspection channel 107a, a maintenance channel 107b, and a waste channel 107c. A transfer position is provided at the intersection of the waste channel 107c outlet and the maintenance channel 107b outlet, and a robotic arm is provided at the transfer position; the rotating disk 108 is used to turn the railcar 200.

[0036] The mobile unit allows the entire maintenance unit to be moved between different locations. It includes a railcar 200, a vehicle that can move on transverse and longitudinal rails 107 for transporting fire extinguishers to different modules of the maintenance unit 100.

[0037] The inspection device 100 is mounted on top of the mobile device and controlled by a controller. The inspection device 100 consists of several modules: a visual inspection module 101 equipped with a visual inspection camera and an infrared 3D scanning camera for inspecting the appearance of the fire extinguisher. Through these cameras, the system can scan and photograph the surface of the fire extinguisher, which is then analyzed by the control system to determine if the fire extinguisher has any obvious visual defects.

[0038] Once the fire extinguisher passes visual inspection, it will be sent to the disassembly module 102 for disassembly. Here, the fire extinguisher tank and nozzle are separated for further inspection and maintenance.

[0039] The cylinder testing module 103 is specifically designed to test the cylinder pressure of fire extinguishers. It includes a water testing mechanism and a cylinder drying mechanism to ensure the safety and reliability of the fire extinguisher cylinder under pressure.

[0040] The tested fire extinguishers are then sent to filling module 104, which includes an extinguishing agent filling mechanism and a motive gas filling mechanism. The extinguishing agent and motive gas are filled into the fire extinguisher to ensure its full functionality.

[0041] After filling, the fire extinguisher will enter the airtightness testing module 105 for airtightness and pressure testing. This step ensures that the fire extinguisher can work normally in actual use without leakage.

[0042] The transport assembly is responsible for moving the fire extinguisher from one module to another. It includes a locking mechanism, a transverse slide rail 107, a longitudinal slide rail 108, and a rotating disc 108. The locking mechanism is used to hold the fire extinguisher, while the transverse slide rail 107, the longitudinal slide rail 107, and the rotating disc 108 are responsible for movement and steering.

[0043] The transverse and longitudinal slide rails 107 are used to move the fire extinguisher. The transverse slide rails include an inspection channel 107a, a maintenance channel 107b, and a disposal channel 107c, which are used to send the fire extinguisher for inspection, maintenance, and disposal, respectively. The longitudinal slide rails 107 connect these slide rails to ensure that the fire extinguisher can move smoothly between different modules.

[0044] A transfer station is located at the intersection of the waste disposal lane 107c exit and the maintenance lane 107b exit, where a robotic arm is installed to transfer fire extinguishers from either the maintenance lane 107b or the waste disposal lane 107c to the next processing location.

[0045] The rotary table 108 is used to steer the railcar 200 so that the fire extinguishers can be accurately delivered to the different modules of the maintenance unit 100.

[0046] The system's design automates the inspection and maintenance process of fire extinguishers, reducing manual intervention and improving maintenance efficiency and safety. This integrated design allows fire extinguisher maintenance to be performed anywhere, eliminating the need to transport fire extinguishers to a centralized maintenance center, significantly saving time and costs.

[0047] Example 2

[0048] Referring to Figure x, which is the second embodiment of the present invention, this embodiment differs from the first embodiment in that: the locking mechanism includes a railcar 200 that can move on the transverse slide rail, the longitudinal slide rail 107 and the rotating disk 108, and a magnetic fixing part disposed on the railcar 200.

[0049] Furthermore, the cylinder detection module 103 includes a water testing mechanism and a cylinder drying mechanism, the filling module 104 includes a fire extinguishing agent filling mechanism and a motive gas filling mechanism, and the rotating disk 108 includes a rotatable disk body, a rotating track set on the disk body, and a rotating motor set below the disk body.

[0050] Furthermore, the lower part of the railcar 200 includes pulleys and a drive motor that slide in cooperation with the transverse slide rail, the longitudinal slide rail 107, and the rotary disk 108. The transverse slide rail also includes a tilting disk 107d, which is driven by a tilting mechanism.

[0051] During use, the locking mechanism is a key component for clamping and securing the fire extinguisher. It includes a railcart 200 and a magnetic fixing part. The railcart 200 can move freely on the transverse slide rails 107, the longitudinal slide rails 107, and the rotating disc 108. This design allows the fire extinguisher to be precisely transported to various modules of the maintenance device 100. The magnetic fixing part is located on the railcart 200 to firmly hold the fire extinguisher, ensuring its stability and safety during transportation.

[0052] The cylinder testing module 103 includes a water testing mechanism and a cylinder drying mechanism. The water testing mechanism is used to test the pressure resistance of the fire extinguisher cylinder to ensure its structural integrity and safety. The cylinder drying mechanism dries the cylinder after the water testing to prevent residual moisture from causing corrosion or other problems, ensuring the long-term reliability of the fire extinguisher.

[0053] The filling module 104 is responsible for filling the fire extinguisher with extinguishing agent and motive gas to restore its functionality. It includes an extinguishing agent filling mechanism and a motive gas filling mechanism. The extinguishing agent filling mechanism is responsible for accurately filling the fire extinguisher with the extinguishing agent, while the motive gas filling mechanism is responsible for filling the motive gas that enables the fire extinguisher to properly spray the extinguishing agent. The coordinated operation of these two mechanisms ensures that the fire extinguisher achieves optimal performance after maintenance.

[0054] The rotating disc 108 is a key component for enabling the railcar 200 to turn. It includes a rotatable disc body, a rotating track mounted on the disc body, and a rotating motor located below the disc body. The rotating motor drives the disc body to rotate, allowing the railcar 200 to change direction between the inspection track 107a, the maintenance track 107b, and the waste track 107c, thereby delivering the fire extinguishers to the correct disposal path.

[0055] The railcar 200 is a carrier for transporting fire extinguishers. Its lower part includes pulleys and a drive motor that slide in conjunction with the transverse slide rail, the longitudinal slide rail 107, and the rotating disk 108. The pulleys ensure the smooth movement of the railcar 200 on the slide rail, while the drive motor provides power, enabling the railcar 200 to move quickly and accurately to the designated position according to the instructions of the control system.

[0056] The transverse slide rail also includes a tilting disc 107d, a mechanism for changing the direction of the fire extinguisher. The tilting disc 107d is driven by a tilting mechanism, allowing the fire extinguisher to be tilted to the appropriate position when needed for more efficient inspection and maintenance operations.

[0057] The collaborative work of these components enables an automated maintenance process for fire extinguishers. From inspection to maintenance and finally to airtightness testing, each step is completed through precise mechanical operation and automated control, which greatly improves maintenance efficiency and accuracy while reducing the risks and costs of manual operation.

[0058] By organically combining the fire extinguisher testing and maintenance equipment and integrating it into the truck chassis, the testing of fire extinguishers becomes more convenient, and its efficiency is significantly improved compared to the existing centralized transportation to the recycling and testing center.

[0059] Example 3

[0060] Referring to Figure 1, this is the third embodiment of the present invention.

[0061] The operating procedure of this device is as follows: the mobile device (including the railcar 200) is moved to the area where fire extinguishers need maintenance, the fire extinguishers in the area are collected, and their appearance is initially inspected manually. Fire extinguishers with obvious defects in appearance will not be included in the maintenance device 100, while fire extinguishers to be inspected are placed in the maintenance device 100.

[0062] Fire extinguishers are inspected via visual inspection module 101, which uses a fixed camera and an infrared flaw detector to scan and photograph the surface. The control system analyzes the surface data. Non-conforming products are sent to the waste disposal channel 107c, while conforming products proceed to the disassembly module 102.

[0063] The fire extinguisher is disassembled in disassembly module 102, separating the tank from the nozzle. The tank undergoes a water pressure test via cylinder detection module 103. Fire extinguishers that pass the test enter maintenance channel 107b for refilling and maintenance, while unqualified products enter waste channel 107c.

[0064] The filling module 104 is responsible for filling the fire extinguisher with extinguishing agent and motive gas. After filling, the fire extinguisher enters the airtightness testing module 105 for airtightness and pressure testing. Qualified products are transported out through the maintenance channel 107b, while unqualified products enter the waste channel 107c. Qualified and unqualified products that have undergone maintenance are sorted and placed separately.
