Description
Technical Field
[0001] This utility model relates to the field of coal mine roadway detection technology, and in particular to a carbon monoxide alarm damper linkage device. Background Technology
[0002] With the large-scale development of my country's economic construction, the mining industry has grown rapidly, its proportion in the national economy has been continuously increasing, its status as a pillar industry has been gradually established, and its role in promoting the overall development of the national economy has become increasingly prominent. Air doors ensure the normal operation of the mine ventilation system. Although they are commonly used infrastructure, they are crucial to the entire mine system. High reliability, stability, and adaptability of air doors are basic requirements for safe underground production. With the continuous advancement of inherently safe mine construction, optimizing the configuration of air doors is an essential and indispensable step. Reasonable improvement and configuration of air doors is an essential and important measure to effectively improve mine ventilation capacity.
[0003] Existing patent: CN202322407301.3 A carbon monoxide alarm damper linkage device, which installs a pneumatic damper between the belt conveyor roadway and the main track roadway, and connects a solenoid valve in series with the damper closing module. The solenoid valve is energized and de-energized by a power-off control module. When the carbon monoxide level in the belt conveyor roadway exceeds the limit, the safety monitoring module issues a power-off command, the power cut-off device executes the action, the solenoid valve is de-energized, and the damper is automatically closed. Thus, carbon monoxide can be monitored in real time when the damper is in use. The carbon monoxide monitoring alarm value can be set according to the needs of the site. When carbon monoxide alarms, an alarm signal is issued. When carbon monoxide exceeds the limit, an alarm signal is issued and the damper is automatically closed at the same time, thus achieving the effect of intelligent detection and isolation. Personnel can manually open the damper without obstructing personnel passage, further increasing the practicality of the device.
[0004] However, in this comparison, the installation of the door frame requires fixing it to the building's doorway using bolts, etc. This installation process requires drilling holes in the inner wall of the building's doorway. Drilling holes in the building's doorway generates dust and noise, making the installation of the carbon monoxide alarm damper linkage device quite laborious. It also requires the use of an electric drill, making it highly dependent on an electric drill, thus reducing the practicality of the carbon monoxide alarm damper linkage device.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a carbon monoxide alarm damper linkage device, including a door frame 1, a hinge 13 and a door 12, two doors 12 are adapted to the door frame 1, the male leaf of the hinge 13 is fixedly connected to the front surface of the corresponding door 12, and the female leaf of the hinge 13 is fixedly connected to the front surface of the door frame 1.
[0033] The door frame 1 is provided with multiple sets of installation mechanisms, including device positioning groove 2, limit slider 3, support groove 4, support slider 5, connecting block 6, countersunk groove 7, sliding hole 8, fixing bolt 9, threaded hole 10 and connecting groove 11.
[0034] Furthermore, two positioning grooves 2 are formed on the outer surface of the door frame 1;
[0035] Two support grooves 4 are formed on the inner wall of the door frame 1, and two positioning grooves 2 are connected to the interior of the two support grooves 4.
[0036] Furthermore, the two support sliders 5 are slidably connected to the two support grooves 4;
[0037] Among them, two support sliders 5 are fixedly connected to two limit sliders 3, and two limit sliders 3 are slidably connected to two positioning grooves 2.
[0038] Furthermore, the vertical cross-section of the limit slider 3 is triangular, and the two limit sliders 3 are set in a mirror image;
[0039] The connecting block 6 is fixedly connected between the two support sliders 5.
[0040] Furthermore, the connecting groove 11 is formed on the inner wall of the door frame 1, and the connecting groove 11 extends into the two support grooves 4;
[0041] The connecting groove 11 is slidably connected to the connecting block 6, and the countersunk groove 7 is opened on the outer surface of the connecting block 6 away from the limiting slider 3.
[0042] Furthermore, the sliding hole 8 is opened on the outer surface of the connecting block 6 near the limiting slider 3, and the sliding hole 8 communicates with the inside of the countersunk groove 7;
[0043] Among them, the fixing bolt 9 is slidably sleeved on the connecting block 6 through the sliding hole 8;

[0045] Furthermore, in the initial state, the limiting slider 3 is in the positioning groove 2. At this time, the door frame 1 is placed vertically in the pre-reserved doorway of the building. Because the width of the door frame 1 is relatively wide in this scheme, when the fixing bolt 9 is threaded into the threaded hole 10, and as the fixing bolt 9 is rotated, the connecting block 6 can be driven to move towards the inner wall of the door frame 1, thereby synchronously driving the supporting slider 5 and the limiting slider 3 to move synchronously, thereby synchronously driving the two limiting sliders 3 to move to the outer surface of the door frame 1. In this process, the inclined surfaces of the two limiting sliders 3 are in contact with the building. The front and rear outer surfaces of the reserved door opening are in contact, and the inclined surfaces of the two limiting sliders 3 clamp and fix the reserved door opening to the upper or left and right sides, thereby fixing the door frame 1 to the reserved door opening, so that the door frame 1 cannot move forward, backward, up, down, or left and right, thus realizing the installation of the door frame 1. The installation is convenient, and there is no need to drill holes in the door opening of the building during the installation process, avoiding the dust and noise generated during drilling. The installation is convenient for subsequent disassembly, reducing the limitations of installation, and thus increasing the practicality of the carbon monoxide alarm damper linkage device.

The door frame 1 and the door 12 are based on the existing patent: CN202322407301.3 A Carbon Monoxide Alarm Damper Linkage Device, which will not be described in detail here. The door frame 1 and the door 12 are equipped with a main control board, a solenoid valve, a power-off control module, a damper closing module, an electric push rod, a wind deflector, an alarm module, a small door, and a safety monitoring module, which enable the door frame 1 and the door 12 to monitor carbon monoxide in real time. At the same time, after the detection is completed, the damper can be automatically closed, thereby achieving the effect of intelligent detection and isolation.
