[0032] The first travel switch 5 and the second travel switch 11 are fixed to the outer frame 6 respectively. The contacts of the first travel switch 5 and the second travel switch 11 are arranged corresponding to the two limit displacement points of the first blocking body 15 respectively to realize the function of automatic control blocking.

[0036] In addition, a foldable and stretchable dust cover 46 is connected between the outer frame 6 and the first blocking body 15 and between the outer frame 6 and the second blocking body 10 respectively.

[0037] The use principle and working process of the electric push rod 21 driving mode of the present invention are as follows:

[0038] When a fire occurs and smoke alarm is triggered, the fire alarm automatic control device automatically or manually starts the electric push rod 21 to extend, driving the second sealing body 10 and the first sealing body 15 to approach each other in turn. When the first guide wheel 2 and the second guide wheel 13 approach the limit rail 29 respectively, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 are in close contact with the elastic fireproof material 33. At the same time, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 tightly clamp the two sides of the elastic fireproof module 4 respectively, and then trigger the second travel switch 11. The electric push rod 21 stops extending, completing the sealing of the through hole 28 of the building.

[0039] Similarly, when the fire alarm is lifted, the fire alarm automatic control device automatically or manually starts the electric push rod 21 to retract, driving the second sealing body 10 and the first sealing body 15 to separate in opposite directions in turn. When the first guide wheel 2 and the second guide wheel 13 approach the limit rail 29 respectively, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 are separated from the elastic fireproof material 33. At the same time, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 are also separated from the two sides of the elastic fireproof module 4 respectively until the building through hole 28 is fully opened, triggering the first travel switch 5, and the electric push rod 21 stops retracting, completing the opening of the building through hole 28.

[0040] The use principle and working process of the motor 35 driving mode of the present invention are as follows:

[0041] When a fire occurs and a smoke alarm is triggered, the fire alarm automatic control device automatically or manually starts the motor 35 to rotate, driving the active sprocket 41 and the passive sprocket 43 to rotate synchronously, thereby driving the second sealing body 10 and the first sealing body 15 to approach each other. When the first guide wheel 2 and the second guide wheel 13 approach the limit rail 29 respectively, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 are in close contact with the elastic fireproof material 33. At the same time, the first fireproof sealing plate 3 and the second fireproof sealing plate 18 tightly clamp the two sides of the elastic fireproof module 4 respectively, and then trigger the second travel switch 11. The motor 35 stops extending, completing the sealing of the through hole 28 of the building, so as to achieve the effect of replacing the electric push rod.

[0042] Similarly, when the fire alarm is lifted, the fire alarm automatic control device automatically or manually starts the motor 35 to reverse, driving the active sprocket 41 and the passive sprocket 43 to rotate synchronously, thereby driving the second blocking body 10 and the first blocking body 15 to separate in opposite directions. When the first guide wheel 2 and the second guide wheel 13 approach the limit rail 29 respectively, the first fireproof blocking plate 3 and the second fireproof blocking plate 18 are separated from the elastic fireproof material 33. At the same time, the first fireproof blocking plate 3 and the second fireproof blocking plate 18 are also separated from the two sides of the elastic fireproof module 4 respectively until the building through hole 28 is fully opened, triggering the first travel switch 5, and the motor 35 stops retracting, completing the opening of the building through hole 28, so as to achieve the function of replacing the electric push rod.

[0043] In the present invention, the first fireproof sealing plate 3, the second fireproof sealing plate 18 and related accessories can be designed as one-way or two-way multiple groups of docking to close or open multiple building penetration holes 28, and each installation position can be designed according to actual needs to achieve the purpose of blocking multiple building penetration holes 28.

[0044] The present invention can also be applied to through holes in special buildings, holes in logistics transmission systems, holes in rail logistics transmission systems, power industries and tunnels, fire isolation areas, etc., and is particularly useful for various through hole systems.

[0045] The present invention uses a fire alarm as a starting signal and adopts a fire blocking module to block the through holes in the building, which not only improves the safety and fire protection coefficient and efficiency, but also has a simple structure, low design cost, and simplifies the maintenance of the through objects in the elastic fire blocking module.

[0046] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
