Description
Technical Field
[0001] The invention relates to the technical field of coal mine equipment, and in particular to a novel full-gas-controlled damper automatic device. Background Art
[0002] Mine air doors are key equipment in the ventilation system of coal mines. They are mainly used to adjust and control the wind direction and air volume in the mine to ensure smooth air circulation in the mine and meet the normal breathing and production needs of miners. At the same time, they can effectively prevent the accumulation of harmful substances such as gas and coal dust, and provide miners with a relatively safe working environment. They play a vital role in ensuring safe production in coal mines. In the prior art, the damper automatic device generally adopts an air cylinder to pull the oil wire rope to complete the opening and closing of the damper. The oil wire rope is exposed to harsh conditions such as moisture, corrosion, wear and tear for a long time, and it is easy to rust, deform, and break. The damper is often blocked and the opening and closing is not smooth during operation. The broken oil wire rope can easily cause personal injury. In addition, the door body is generally made of wood, which is exposed to harsh conditions such as moisture, corrosion, wear and tear for a long time, and is easy to deform, damage and fireproof. Therefore, the present invention proposes a novel fully air-controlled damper automatic device to solve the problems existing in the prior art. Summary of the invention

[0025] It also includes a control system, which includes a main controller, a pneumatic locking component, an infrared sensor, a camera and an audible and visual alarm. The pneumatic locking component is installed on the door body 2, and the door body 2 is locked with the door frame 1 by the pneumatic locking component. The infrared sensor is used to detect people or objects near the door body 2, and the camera is used to capture the real-time image of the door body 2, monitor the opening and closing status of the door body 2 and the passage of pedestrians. The infrared sensor and the camera transmit data to the main controller, and the signal feedback end of the pneumatic locking component is connected to the main controller.

The main controller has a built-in recording unit for recording the control records of the pneumatic locking components of different door bodies 2, and marking the timestamp at the same time to provide a time retrieval function. When in use, the infrared sensor and camera collect data, and the main controller is used to determine whether the two door bodies 2 are open or locked. When one door 2 is opened and the other door 2 is locked, the sound and light alarm displays "locked" at the other door 2. When one door 2 is closed, the other door 2 releases the lock of the pneumatic locking component, and the sound and light alarm switches to display "pass" at the other door 2, avoiding the failure or human-caused failure of the damper, and the locking is reliable, ensuring that the ventilation system is stably controlled. In coal mining operations, the main purpose of the ventilation system is to ensure air circulation in the mine to remove harmful gases and dust and keep the air fresh. If two dampers are opened at the same time, the air may form a short circuit between the two dampers, resulting in reduced air circulation efficiency. When only one damper is open, the air can pass through the ventilation path more efficiently to ensure that all areas in the mine are fully ventilated. Harmful gases such as gas may exist in the mine. If the ventilation system is unstable or fails, these gases will accumulate and may cause an explosion. Therefore, keeping the ventilation system stable and controlled is crucial to ensure the safety of miners. By ensuring that only one damper is open, the air circulation in the mine can be more effectively controlled and the safety risk can be reduced. Ensure that when one damper is opened, the other damper will automatically close to prevent airflow short circuit. At the same time, fault alarm and emergency unlocking functions can also be provided to ensure that measures can be taken quickly in an emergency.
[0026] The novel fully pneumatically controlled damper automatic device adopts a pneumatically controlled component as a power source to drive the first linkage arm 9 to rotate, and the first linkage arm 9 drives the second linkage arm 10 to rotate, pushing the connecting rod 11, so that the connecting ear 16 moves along the straight groove 4, and the first protrusion 6 moves to one end of the straight groove 4. When the second protrusion 7 moves to the guide protrusion 8 and is guided, it moves to the arc groove 5, and cooperates with the second linkage arm 10 to rotate itself during the pushing process, so that the second protrusion 7 moves along the arc groove 5, and the connecting ear 16 rotates with the first protrusion 6 as the base point, thereby opening the door body 2, and closing it on the contrary. The movement is smooth, the installation and use are convenient, safe, reliable, and not easy to hurt people. The present invention collects data through infrared sensors and cameras, and cooperates with the main controller to determine whether the two door bodies 2 are open or locked. When one door body 2 is opened and the other door body 2 is locked, the sound and light alarm displays "locked" at the other door body 2. When one door body 2 is closed, the other door body 2 releases the lock of the pneumatic locking component, and the sound and light alarm switches to display "pass" at the other door body 2, avoiding the failure or human-caused air door not being closed, and the locking is reliable, ensuring that the ventilation system is stably controlled. At the same time, a layer of fire-retardant coating is applied on the surface of the door body 2, which can reduce the flammability of the material and slow down the spread of the flame, thereby improving the fire resistance limit of the material. It has multiple functions such as flame retardant, rust-proof, waterproof, and wear-resistant.
