A slider is slidably connected to the inner wall of the slide rail, and a pressing block is fixedly connected to the outer wall of the slider. A spring is fixedly connected to the top of the slider. The driving assembly includes a moving plate fixed to the outer wall of the slider. A fixed frame is fixedly connected to the outer wall of the moving plate. A first connecting rod is rotatably connected to the inner wall of the fixed frame. A second connecting rod is rotatably connected to the outer wall of the first connecting rod. A third connecting rod is rotatably connected to the inner wall of the second connecting rod. A second support frame is fixedly connected to the top of the support plate. A rotating block is rotatably connected to the inner wall of the second support frame. A foot pedal is fixedly connected to the outer wall of the rotating block. A first support frame is fixedly connected to the top of the support plate. A center rod is fixedly connected to the inner wall of the first support frame.

[0007] Preferably, the top of the support plate is provided with a fixing mechanism for fixing the air foam fire extinguishing device. The fixing mechanism includes a fixing plate fixed to the inner wall of the support plate. A bidirectional threaded rod is rotatably connected to the inner wall of the fixing plate, and an output rod is fixedly connected to the outer wall of the bidirectional threaded rod.

[0008] Preferably, a handle is fixedly connected to the outer wall of the output rod, an insert rod is slidably connected to the inner wall of the handle, a feed block is fixedly connected to the top of the support plate, and the inner wall of the feed block is rotatably connected to the outer surface of the output rod.

[0009] Preferably, a limiting plate is fixedly connected to the outer wall of the transfer block, and there are two fixing plates, with an auxiliary rod fixedly connected to one side of the two fixing plates that are close to each other.

[0010] Preferably, the outer surface of the bidirectional threaded rod is threaded with a threaded block, the inner wall of the threaded block is slidably connected to the outer surface of the auxiliary rod, and a clamping block is fixedly connected to the outer wall of the threaded block.

[0011] Preferably, the outer surface of the central rod is rotatably connected to the inner wall of the second connecting rod, the outer wall of the third connecting rod is rotatably connected to the inner wall of the pedal, the end of the spring away from the slider is fixedly connected to the inner wall of the slide rail, a push rod is fixedly connected to the top of the support plate, and several universal wheels are fixedly connected to the bottom of the support plate.

[0012] This utility model has the following beneficial effects: 1. The compressed air foam fire extinguishing device used for fire inspection of the main transformer system in this substation operates by stepping on a foot pedal, which rotates a fixed block at its bottom inside a support frame. When the pedal moves, it pulls a connecting rod three, causing connecting rod two, which is rotatably connected to connecting rod three, to rotate on the outer surface of the central rod. When connecting rod two rotates, it pulls connecting rod one, which in turn pulls the fixed frame downwards. This causes a movable plate fixed to the outer wall of the fixed frame to move simultaneously. As the movable plate moves, a slider fixed to its outer wall slides along the inner wall of the slide rail. At the same time, a pressing block fixed to the outer wall of the slider also moves, pressing down the triggering device of the air foam fire extinguishing device. Simultaneously, the spring is stretched. This facilitates the triggering of the air foam fire extinguishing device and prevents excessive thrust during triggering, which could injure the user.

[0013] 2. The compressed air foam extinguishing device used for fire inspection of the main transformer system in this substation rotates by turning the handle, which drives the output rod to rotate. When the output rod rotates, the bidirectional threaded rod also rotates. At this time, the threaded block moves along the groove of the bidirectional threaded rod. The threaded block slides on the auxiliary rod at the same time, which limits the movement of the threaded block and prevents it from rotating with the bidirectional threaded rod. When the threaded block moves, the clamping block also moves at the same time, thereby fixing the air foam extinguishing device. At this time, the insertion rod is inserted through the handle into the limiting plate to limit it. The advantage of this is that it can fix the air foam extinguishing device and replace it at the same time.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] This utility model provides two technical solutions: Figures 1-3 The first embodiment is shown: a compressed air foam fire extinguishing device for fire inspection of the main transformer system of a substation, including a support plate 1, a pressing mechanism is provided on the top of the support plate 1 for convenient use of the air foam fire extinguishing device, and a drive component is provided on the top of the support plate 1.

A support frame 14 is fixedly connected to the top of the support plate 1. A center rod 13 is fixedly connected to the inner wall of the support frame 14.

[0020] By stepping on the pedal 15, the rotating block 16 fixed at its bottom rotates inside the support frame 17. When the pedal 15 moves, it pulls the connecting rod 12 to move. At this time, the connecting rod 11, which is rotatably connected to the connecting rod 12, rotates on the outer surface of the central rod 13. When the connecting rod 11 rotates, it pulls the connecting rod 10 to move. At this time, the connecting rod 10 pulls the fixed frame 9 to move downward, thereby driving the moving plate 8 fixed on the outer wall of the fixed frame 9 to move simultaneously. When the moving plate 8 moves, the slider 5 fixed on its outer wall slides on the inner wall of the slide rail 4. At this time, the pressing block 6 fixed on the outer wall of the slider 5 also moves, thereby pressing down the triggering device of the air foam fire extinguishing device. At the same time, the spring 7 is also stretched.

A handle 26 is fixedly connected to the outer wall of the output rod 25. An insert rod 23 is slidably connected to the inner wall of the handle 26.

Several universal wheels 3 are fixedly connected to the bottom of the support plate 1.

[0022] By rotating the handle 26, the output rod 25 fixed on its outer wall is driven to rotate. When the output rod 25 rotates, the bidirectional threaded rod 24 fixed on its outer wall will also rotate. At this time, the threaded block 20 connected to the threaded surface of the bidirectional threaded rod 24 will move along the groove of the bidirectional threaded rod 24. The threaded block 20 slides on the auxiliary rod 19 at the same time to limit the movement position of the threaded block 20 and prevent it from rotating with the rotation of the bidirectional threaded rod 24. When the threaded block 20 moves, the clamping block 27 fixed on its outer wall will also move at the same time, thereby fixing the air foam fire extinguishing device. At this time, the insertion rod 23 is inserted through the handle 26 into the limiting plate 22 to limit it.
