[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] Example 1
[0031] This embodiment provides a platform type compressed air foam fire extinguishing device for transformer fire extinguishing, such as Figure 1-5 As shown, it includes a chassis frame 3, a scissor-type lifting frame 1 is arranged on the chassis frame 3, a mounting platform 6 is arranged on the top of the scissor-type lifting frame 1, a main line module 13 and a fire monitor 9 are arranged on the mounting platform 6, the liquid outlet of the main line module 13 is connected to the fire monitor 9 through a flange, and the liquid inlet 15 of the main line module 13 is connected to the liquid outlet of the CAFS system generating device through a quick interface. Since the CAFS system generating device is a conventional technology, it will not be described one by one here.
[0032] For example Figure 1 As shown, the scissor-type lifting frame 1 is formed by four scissor-type units hinged in sequence from bottom to top. The first scissor-type unit is movably connected to the third scissor-type unit through an electric hydraulic push rod 2. The two sides of the bottom of the first scissor-type unit are movably connected to two horizontal rods respectively, one of which is fixedly connected to the base frame at both ends, and the other horizontal rod is slidably connected to the chassis frame 3.
[0033] Specifically, a guide rod is further provided on the other horizontal rod, and a limit block is further provided on the chassis frame 3. The limit block is located on one side of the sliding horizontal rod, and the guide rod passes through the limit hole of the limit block.
[0034] When the fork frame units are in the stowed and folded state, the fork frame units can be naturally stacked and supported only by the fork frame units themselves; when the fork frame units are in the raised and unfolded state, the fork frame units are supported by the electric hydraulic push rod 2.
[0035] A limit switch 12 is also provided on the chassis frame 3, where the limit switch 12 is used to limit the maximum and minimum heights of the telescopic platform, ensuring that the platform can stop at a maximum height of 3 meters to avoid continuous rise until the telescopic rod is damaged. Ensure that the telescopic rod stops after retracting to a natural state to avoid continuous descent to damage the push rod motor 8.
[0036] The bottom of the chassis frame 3 is also provided with casters 5, and a foot support is provided at the bottom of the chassis frame 3. The foot support includes a movable rod and a foot 4. One end of the movable rod is hinged to the side wall of the chassis frame 3, and the foot 4 is provided at the other end of the movable rod. When the chassis frame 3 is in a walking state, the movable rod rotates toward the chassis frame 3 and gathers and is stored at the front and rear walls of the chassis frame 3, and the foot 4 is retracted. When the chassis frame 3 moves to the fire extinguishing position, the movable rod rotates outward and puts down the foot 4, and the chassis frame 3 is stabilized at the current position by using the foot 4. The stable foot 4 ensures that the device does not shake violently when working.
[0037] A push rod (handle) is also provided on the chassis frame 3, and a button control box 11 is also provided on the side wall of the push rod (handle). The button control box 11 is provided with up and down control keys and an emergency stop, which are used to control the up and down movement of the scissor-type lifting frame 1 on site, and an emergency stop is performed in case of an emergency to ensure the safety of personnel.
[0038] The chassis frame 3 is also provided with a battery 7 and a control box 14, and the electric hydraulic push rod 2 is provided with a push rod motor 8 and an oil tank (which is a common structure of the electric hydraulic push rod 2, which has not been improved here and is not a protection point of this application, so it will not be described one by one). Here, the push rod motor 8 is the power source of the electric hydraulic push rod 2, and the battery 7 supplies power to the fire monitor 9 and the electric hydraulic push rod 2.
[0039] A main switch 10 is provided on the control box 14. The main switch 10 controls the power supply of the device to be closed and disconnected. When the device is started, the control power switch is turned on; when the device is finished working, the control power switch is turned off.
[0040] The connection end between the fire monitor 9 and the main line module 13 is provided with a horizontal rotating part 18, and a column mist conversion part 17 is provided at the liquid outlet of the fire monitor 9, and a vertical rotating part 19 is provided at the bent horizontal section of the fire monitor 9. The horizontal rotating part 18, the vertical rotating part 19 and the column mist conversion part 17 are all electrically connected to the wireless remote control (wireless connection, WIFI or Bluetooth connection can be used). The CAFS flow rate is adjustable in 5-10L, and it is electronically controlled. The CAFS spraying mode is adjustable in column mist. The horizontal rotation angle is 0~360°, and the vertical rotation angle is -45°~+90°. Figure 6 , Figure 7 shown.
[0041] The fire monitor 9 is equipped with a camera 16. Both the fire monitor 9 and the camera 16 meet the requirement of high temperature resistance of 600 degrees, and the remote control signal receiving distance is up to 150m.
[0042] The camera 16 takes pictures and displays the current position of the fire monitor 9 through the wireless remote control, and adjusts the vertical rotation angle of the fire monitor 9 by remotely controlling the vertical rotating member 19, and adjusts the overall horizontal rotation angle of the fire monitor 9 in cooperation with the horizontal rotating member 18. The angle of the fire monitor 9 is adjusted by cooperating with the vertical rotating member 19 through the horizontal rotating member 18. The horizontal rotating member 18 and the vertical rotating member 19 mentioned here are conventional technologies in the art (refer to the ground joystick), and will not be described one by one here.
[0043] When the fire-fighting device is working, the main pipeline module 13 and the fire monitor 9 on the platform (which is an existing mature technology, and the entire CAFS system is directly adopted in this application, and no improvement is made here) are raised to a suitable position. After the CAFS system generator is started, the foam is connected to the fire monitor 9 of this device through a water hose and sprayed out. The remote controller can control the fire monitor 9 at a maximum distance of 150m.
[0044] Example 2
[0045] When using the platform type compressed air foam fire extinguishing device in Example 1 to extinguish a fire, the specific operation process is as follows:
[0046] (1) When the fire alarm is triggered, the staff pushes the fire-fighting equipment out of the equipment compartment, reaches the fire location, rotates the movable rod outward and lowers the foot 4 to fix the entire equipment;
[0047] (2) The water hose is connected to the injection port of the main pipeline module 13 and connected to the quick interface, and the electric hydraulic push rod 2 is started to open the scissor-type lifting frame 1 to lift the fire monitor 9 on the installation platform 6 to the appropriate position of the tearing hole.
[0048] (3) Operate the wireless remote control to adjust the fire monitor 9 to a suitable angle by capturing the image through the camera 16.
[0049] (4) Open the valve on the quick interface (the CAFS generator detects a fire alarm and starts automatically or manually) and high-quality compressed air foam is output through the main line module 13 and the outlet of the fire monitor 9 to control the fire.
[0050] After the fire alarm is lifted, the CAFS system generator is manually turned off. After the foam liquid is sprayed, the scissor lift frame 1 is lowered, the hose is removed, the valve at the quick connector is closed, the foot 4 is retracted, and the frame is pushed back into the equipment compartment.
[0051] The above is only a preferred embodiment of the utility model and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the technical essence of the utility model still falls within the protection scope of the technical solution of the utility model.
