Description

Technical Field

[0001] The utility model relates to the technical field of mine air doors, in particular to a mine air door based on an AI intelligent analysis camera. Background Art

[0002] Mine dampers based on AI intelligent analysis cameras are designed to improve the operating efficiency and safety of mine ventilation systems. The basic structure of this type of mine damper consists of a camera, an AI algorithm, a control unit, a communication module, and a damper. The camera is responsible for capturing images of people and vehicles entering and leaving the mine. The AI ​​algorithm identifies people and vehicles by analyzing the images and measures their distance and angle from the damper. The control unit receives the analysis results of the AI ​​algorithm, controls the opening and closing of the damper, and achieves precise adjustment of the ventilation system. The communication module enables the system to communicate and transmit data remotely with other equipment or monitoring centers to achieve real-time monitoring and remote control;

[0003] For example, an AI video safety management and control system for underground air doors in a coal mine disclosed in the authorization announcement number CN117119175B includes a data acquisition module, an abnormality analysis module, a comprehensive screening module, an impact assessment module, a comparison module and an early warning module; the data acquisition module collects parameter information of the AI ​​intelligent analysis camera during operation, including system parameter information and imaging parameter information, and monitors the AI ​​intelligent analysis camera. When an abnormality occurs in the operating state of the AI ​​intelligent analysis camera, which may cause the recognition accuracy of the AI ​​intelligent analysis camera to deteriorate, the staff is prompted to recognize the AI ​​intelligent analysis camera. The accuracy may be affected, and the damper control based on AI video analysis may become inaccurate, thereby effectively preventing staff from continuing to enter or driving in and causing dangerous situations. However, the mine damper opening and closing structure adopted in this technical solution is still a pneumatic structure composed of door leaves, balancing mechanisms, pulleys, wire ropes, counterweights, cylinders and other components. In the humid, dusty and high-temperature underground mine environment, the cylinder is prone to failure due to poor sealing or wear, the pulley and wire rope are prone to wear due to friction, and the counterweight has problems due to uneven force. Its failure rate is relatively high, affecting the stability of the mine damper system. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mine air door based on an AI intelligent analysis camera comprises a circular door frame and a T-shaped shaft seat fixed at the corner position of the back side of the circular door frame, a support plate is fixed on the outer wall of the T-shaped shaft seat on the side away from the central reference plane of the circular door frame, a door leaf monomer is installed between two of the T-shaped shaft seats in the same vertical direction, a U-shaped hollow frame is fixed on the back side of the circular door frame above the two door leaf monomers, and a servo motor is installed on the top of the U-shaped hollow frame.

A connecting rod pushing structure for driving the door leaf monomer to rotate and swing is installed on the outer wall of one side of the support plate, and a control panel electrically connected to the input end of the servo motor is installed on one side of the surface of the circular door frame.

[0006] Preferably, the connecting rod pushing structure includes a support seat fixed on the outer wall of one side of the support plate, and an arc-shaped connecting rod hingedly installed on the top of the support seat, one end of the arc-shaped connecting rod is fixedly connected to the outer wall of one side of the door leaf unit, the connecting rod pushing structure also includes a main connecting rod fixedly installed on one end of the surface of the vertical beam axis, and a secondary connecting rod hingedly installed on the top of the main connecting rod, one end of the secondary connecting rod is hinged to the other end of the main connecting rod.

[0007] Preferably, an arc-shaped connecting arm is fixed between the two arc-shaped connecting rods in the same vertical direction.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the mine damper structure based on AI intelligent analysis camera no longer requires multiple components such as balancing mechanism, pulley, wire rope, counterweight and cylinder. Instead, the door leaf unit is directly driven to open and close through components such as servo motor and connecting rod pushing structure, which reduces the number of parts and reduces the complexity of the damper system. Compared with the cylinder, the motor can start and stop faster, thereby controlling the opening and closing of the damper faster. This has higher safety and real-time performance for emergencies that may occur in the mine environment, such as gas leakage or fire. BRIEF DESCRIPTION OF THE DRAWINGS

Vertical beam shafts 7 are rotatably installed on both sides of the top of the U-shaped hollow frame 5. The top of the vertical beam shaft 7 extends to the inside of the U-shaped hollow frame 5 and is connected to the worm gear self-locking structure 12. A connecting rod push-pushing structure 8 for driving the door leaf monomer 10 to rotate and swing is installed on the outer wall of one side of the support plate 4. A control panel 2 electrically connected to the input end of the servo motor 6 is installed on one side of the surface of the circular door frame 1;

[0021] The control panel 2 includes a processor, a memory, a communication module and an input / output interface. The processor is used to execute the AI ​​algorithm and process the control logic, the memory is used to save system parameters and historical data, the input / output interface communicates with the damper control system, and the communication module can communicate remotely and transmit data with the servo motor 6 in the damper;

[0022] The worm gear self-locking structure 12 includes a worm gear monomer 1202 installed on the top of the vertical beam shaft 7, and a worm shaft 1201 rotatably installed on one side of the U-shaped hollow frame 5. The worm shaft 1201 and the worm gear monomer 1202 are meshed with each other, and a bevel gear transmission structure 1203 is installed at one end of the worm shaft 1201. The bevel gear bidirectional drive component 11 includes a driven shaft 1101 symmetrically rotatably installed on both sides of the U-shaped hollow frame 5, and a bevel gear transmission structure 1102 installed at the output end of the servo motor 6 for driving the two driven shafts 1101 to rotate synchronously in the opposite direction. The rotary power of the servo motor 6 is transmitted to the driven shaft 1101 through the bevel gear transmission structure 1102, and at this time, the two driven shafts 1101 rotate synchronously in the opposite direction;

[0023] The other end of the driven shaft 1101 is connected to the second bevel gear transmission structure 1203. The driven shaft 1101 uses the second bevel gear transmission structure 1203 to drive the worm shaft 1201 to rotate, so that the worm shaft 1201 drives the worm gear monomer 1202 and the vertical beam shaft 7 to rotate. The worm gear self-locking structure 12 can make the damper automatically locked after reaching the specified position, keep it in a stable position, and prevent accidental opening or closing;

[0024] The connecting rod pushing structure 8 includes a support seat 801 fixed on the outer wall of one side of the support plate 4, and an arc-shaped connecting rod 802 hingedly installed on the top of the support seat 801, one end of the arc-shaped connecting rod 802 is fixedly connected to the outer wall of one side of the door leaf monomer 10, and the connecting rod pushing structure 8 also includes a main connecting rod 803 fixedly installed on one end of the surface of the vertical beam shaft 7, and a secondary connecting rod 804 hingedly installed on the top of the main connecting rod 803, one end of the secondary connecting rod 804 and the other end of the main connecting rod 803 are hinged to each other. When the vertical beam shaft 7 is driven to rotate, the rotational motion of the vertical beam shaft 7 is converted into the rotational swing motion of the arc-shaped connecting rod 802 through the main connecting rod 803 and the secondary connecting rod 804. The support seat 801 serves as the rotation center of the arc-shaped connecting rod 802, and then the arc-shaped connecting rod 802 drives the arc-shaped connecting arm 9 and the door leaf monomer 10 to rotate and swing, thereby realizing the opening and closing action of the door leaf monomer 10;

[0025] An arc-shaped connecting arm 9 is fixed between two arc-shaped connecting rods 802 in the same vertical direction. The arc-shaped connecting arm 9 is made of aluminum alloy. A rectangular hollow portion is provided on the arc surface wall of the arc-shaped connecting arm 9. The arc-shaped connecting arm 9 makes the movement of the door leaf unit 10 during the opening and closing process more stable and smooth, and the structural design of the arc-shaped connecting arm 9 can balance the stress of the door leaf, reduce the deformation and damage of the door leaf and the connecting rod, and extend the service life of the damper.

[0026] When the embodiment of the present application is in use, first, the staff can install an AI intelligent analysis camera on the upper frame of the circular door frame 1, which captures and identifies the images of people and vehicles entering and leaving the mine, and sends the identification results to the control panel 2. The control panel 2 then sends a working signal to the servo motor 6, which controls the servo motor 6 to work in the set direction, speed, angle, and response time to achieve the opening and closing of the door leaf unit 10. In this process, the rotary power of the servo motor 6 is transmitted to the two worm gear self-locking structures 12 through the bevel gear bidirectional drive assembly 11. The two worm gear self-locking structures 12 act synchronously and in reverse, and the vertical beam shaft 7 is driven to rotate. At this time, the rotational motion of the vertical beam shaft 7 is converted into a swinging motion of the door leaf unit 10 through the connecting rod push structure 8, so that the door leaf unit 10 The door leaf unit 10 is opened and closed by rotating with the T-axis seat 3 as the central axis. The servo motor 6, bevel gear bidirectional drive assembly 11 and other components can accurately control the opening angle and closing speed of the door leaf unit 10 to ensure the synchronous and stable opening and closing of the two door leaf units 10. The damper structure no longer requires multiple components such as a balancing mechanism, a pulley, a wire rope, a counterweight and a cylinder. Instead, the servo motor 6, a connecting rod push structure 8 and other components are used to directly drive the opening and closing of the door leaf unit 10, thereby reducing the number of components and the complexity of the damper system. Compared with the cylinder, the motor can start and stop faster, thereby controlling the opening and closing of the damper faster. This has higher safety and real-time performance for emergencies that may occur in a mine environment, such as gas leaks or fires.
