[0007] By providing a rolling door body, a sliding rail, a speed measuring component, a door frame, a placement base, a storage bin, a positioning opening and a support frame, the cooperation of the sliding rail, the door frame and the positioning opening can limit the equipment when it is out of control, delay the falling time, and reduce the impact force. By providing a side speed component, the equipment can be restricted when it is out of control, thereby increasing the safety of the equipment.

[0008] In a preferred solution, the speed measuring assembly includes four mounting frames, one side outer walls of the four mounting frames are respectively fixedly connected to the two side outer walls of the rolling door body, and one side outer walls of the four mounting frames are fixedly connected with a protective plate; the inner walls on the opposite sides of every two of the protective plates are movably connected with the same sliding bin, and the outer walls of the two sliding bins are provided with two ejection outlets; the two side inner walls of the two sliding bins are fixedly connected with connecting columns, the outer walls of the two connecting columns are fixedly connected with two connecting plates, and one side outer walls of the four connecting plates are fixedly connected with a telescopic spring rod; one end of the four telescopic spring rods is fixedly connected with a positioning head, and the four positioning heads are respectively located inside the two sliding bins.

[0009] By providing a speed measuring component and through the cooperation of the telescopic spring rod and the locking head, when the sliding compartment slides too fast, the telescopic spring rod can be stretched out due to centrifugal force, and the locking head can be ejected from the ejection outlet and locked into the locking port, thereby locking the out-of-control rolling door body, increasing the safety of the equipment and avoiding the possibility of personal injury.

[0010] In a preferred solution, one side outer wall of one of the door frames is fixedly connected to a protective plate, one side outer wall of the protective plate is fixedly connected to a fixing column, the outer wall of the fixing column is movably connected to a mounting column, and the outer wall of the mounting column is fixedly connected to a blocking plate, and one side outer wall of the blocking plate is fixedly connected to a fixing head; one side outer wall of the protective plate is fixedly connected to a mounting head, the interior of the mounting head is movably connected to an electric telescopic rod, an information receiving head is provided on the electric telescopic rod, and the output end of the electric telescopic rod is movably connected to the interior of the fixed head.

[0011] By providing a sensing head, a blocking plate, a fixed column, an information receiving head, a mounting head, a fixed head, an electric telescopic rod, a protective plate and a mounting column, and by cooperating with the signal receiving head and the sensing head, the area under the door can be monitored when the rolling door is out of control. If there is someone underneath, a signal is sent in time to cause the electric telescopic rod to pop out the blocking plate to block the out-of-control rolling door and prevent the people underneath from being injured. Through two layers of protection, the rolling door is strongly limited, thereby improving the comprehensiveness of equipment protection.

[0012] From the above, it can be seen that the automatic sensing protection device for rolling shutter door anti-fall provided by the utility model improves the protective effect of the equipment when the rolling shutter door falls. By setting up a double protection device, the falling of the rolling shutter door is comprehensively prevented, which solves the problem that a single protection measure cannot withstand excessive impact force and causes personal injury, and is more in line with the current demand for rolling shutter door anti-fall.
