[0004] Secondly, the traditional mechanically driven damper has a slow response speed and cannot quickly adapt to the needs of wind flow changes. In a mine, wind flow changes may occur instantly. If the damper cannot respond in time, it may cause wind flow turbulence and even cause safety accidents. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a slope pneumatic push-pull damper structure, such as Figure 1-Figure 6 As shown, it includes a damper main board 2, and there are two damper main boards 2, which are installed in the channel 1 one after the other. An air outlet 21 is opened on the damper main board 2, and a door leaf 3 is arranged on the outer side of the air outlet 21. A horizontal movable rod 4 is connected to one side of the door leaf 3. The horizontal movable rod 4 is driven by the driving cylinder 41 to perform horizontal movement, thereby driving the door leaf 3 to move horizontally, so as to realize the opening and closing of the air outlet 21.

[0026] In this embodiment, a front infrared sensor 6 is installed on the outer side of the damper main board 2 near the front of the channel 1, a rear infrared sensor 8 is installed on the outer side of the damper main board 2 near the rear of the channel 1, and a mid-infrared sensor 7 is installed between the two damper main boards 2 near the channel 1. When a pedestrian approaches the first damper main board 2, the front infrared sensor 6 senses the approaching signal, and controls the driving cylinder 41 of the first damper main board 2 to push and pull the door leaf 3 automatically open through the PLC single-chip computer 9, and the second damper main board 2 is locked at this time; when a pedestrian passes through the first damper main board 2 and approaches the second damper main board 2, the mid-infrared sensor 7 senses the approaching signal, and controls the air outlet 21 of the first damper main board 2 to automatically close through the PLC single-chip computer 9, and the air outlet 21 of the second damper main board 2 to automatically open; when the pedestrian passes through the air outlet 21 of the second damper main board 2 and leaves, the second damper main board 2 is automatically closed. This facility not only realizes automation, but also meets the requirements of anti-burst and anti-wind facilities.

[0027] Specifically, guide rails 5 are installed on the upper and lower sides of the damper main board 2, and sliding sleeves 31 are slidably arranged on the guide rails 5. The upper and lower sides of the door leaf 3 are connected and fixed to the sliding sleeves 31, which is convenient for guiding the door leaf 3 and ensures the stable opening and closing of the door leaf 3.

[0028] Furthermore, a PLC single chip computer 9 is installed above the interior of the channel 1. The PLC single chip computer 9 is used to receive signals from the front infrared sensor 6, the middle infrared sensor 7, and the rear infrared sensor 8, and control the operation of different driving cylinders 41, thereby driving the door leaf 3 to open and close.

[0029] Furthermore, the door leaf 3 includes a steel plate 33, and a buffer layer 34 is arranged on the outer side of the steel plate 33. The buffer layer 34 is made of silicone material and has a certain buffering effect. An anti-corrosion layer 35 is installed on the outer side of the buffer layer 34. The anti-corrosion layer 35 is used to prevent corrosion and avoid damage caused by long-term use.

[0030] Furthermore, the thickness of the steel plate 33 is 10-20 cm, which ensures that the door leaf 3 has good strength.

[0031] Furthermore, the size of the door leaf 3 is larger than the size of the air outlet 21. A sealing strip 32 is installed on the side of the door leaf 3 close to the damper main board 2. The sealing strip 32 is a rectangular structure. When the door leaf 3 is closed, the sealing strip 32 is located on the side of the air outlet 21 to ensure good sealing after the door leaf 3 is closed.

[0032] Furthermore, fixing rods 51 are installed at both ends of the guide rail 5 , and one end of the fixing rod 51 is welded to the outer wall of the damper main board 2 to ensure the fixation of the guide rail 5 and facilitate the flexible sliding of the sliding sleeve 31 .

[0033] When the slope pneumatic push-pull damper structure of the utility model is in use, first, when a pedestrian approaches the front of the passage 1, the front infrared sensor 6 senses the pedestrian's approach signal and transmits the signal to the PLC single chip 9. After receiving the signal, the PLC single chip 9 controls the driving cylinder 41 of the first damper main board 2 to work, and the driving cylinder 41 drives the door leaf 3 to move horizontally through the horizontal movable rod 4, thereby realizing the automatic opening of the air outlet 21. At this time, the second damper main board 2 remains in a locked state to ensure that the air flow does not pass through the two dampers at the same time.

[0034] When a pedestrian passes through the first damper main board 2 and approaches the second damper main board 2, the mid-infrared sensor 7 senses the pedestrian's approach signal and also transmits the signal to the PLC single chip computer 9. After receiving the signal again, the PLC single chip computer 9 controls the air outlet 21 of the first damper main board 2 to automatically close, and controls the air outlet 21 of the second damper main board 2 to automatically open, so that the pedestrian can pass through.

[0035] When a pedestrian passes through the air outlet 21 of the second air door main board 2 and leaves, the rear infrared sensor 8 senses the pedestrian's departure signal and transmits the signal to the PLC single chip computer 9. After receiving the signal, the PLC single chip computer 9 controls the driving cylinder 41 of the second air door main board 2 to work, driving the door leaf 3 to move horizontally, thereby realizing the automatic closing of the air outlet 21.

[0036] During the entire working process, the guide rails 5 and the sliding sleeves 31 installed on the upper and lower sides of the damper main board 2 play a key guiding role, ensuring the stable opening and closing of the door leaf 3. At the same time, the steel plate 33, the buffer layer 34 and the anti-corrosion layer 35 of the door leaf 3 provide sufficient strength, buffer effect and anti-corrosion protection respectively, ensuring the long-term stable use of the damper. The sealing strip 32 ensures that the door leaf 3 has good sealing after closing, effectively preventing the leakage of airflow.

[0037] Finally, it should be noted that the electronic components of the driving cylinder 41, PLC microcontroller 9, etc. in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
