Description

Technical Field

[0001] The utility model relates to the technical field of mine ventilation, in particular to an intelligent light-controlled switch for mines. Background Art

[0002] As one of the eight systems for mine resource exploitation, the mine ventilation system is designed and managed not only to meet the life safety of underground workers, but also to provide a good working environment for underground workers. The mine tunnel automatic damper control system and control method are one of the ways to realize the intelligent construction of tunnel ventilation system.

[0003] The damper is an important structure in the mine ventilation system, which is used to cut off the wind flow, create conditions for the distribution of mine wind flow on demand, and provide convenience for pedestrians and transportation. Nowadays, with the continuous development and progress of science and technology, various dampers of various styles have emerged.

[0004] The most basic requirements that dampers must meet are: ① It is labor-saving, convenient and safe to open; ② It can be closed automatically; ③ It is tightly sealed at all locations to prevent air leakage; ④ Each group of dampers must have no less than two dampers and be equipped with a locking device so that they cannot be opened at the same time; ⑤ In order to prevent airflow short-circuiting when the mine is reversed, the dampers in the main air duct must be equipped with reverse dampers.

[0005] At present, the methods for opening and closing mine dampers include: using automatic dampers with light sensors. When pedestrians or vehicles pass through the dampers, a handheld light source or a vehicle-mounted light source is used to illuminate the light sensor to control the opening or closing of the dampers.

[0006] However, the underground lighting environment is complex and the dust concentration in the air is high. The existing automatic damper control system in mine tunnels has a low level of intelligence and is greatly affected by the environment. Summary of the invention

[0010] The intelligent light-controlled switch for mining in the embodiment of the utility model detects the light change of the external light in real time and compares it with the light intensity of the current underground light. When the intelligent light-controlled switch for mining detects the change of light intensity, the automatic air door control system of the mine tunnel responds immediately to ensure the safe, efficient and rapid passage of pedestrians or vehicles through the air door, which greatly improves the passage efficiency of the air door, ensures the safety of underground personnel, and ensures the safety of underground ventilation.

First, the intelligent light-operated switch for mining according to the embodiment of the utility model will be described with reference to the accompanying drawings.

[0023] Figure 1 The figure is a schematic diagram of the structure of an intelligent light-controlled switch for mining according to an embodiment of the utility model.

[0024] like Figure 1 As shown, the intelligent light-controlled switch 10 for mining includes: a plurality of sensors 100 , a controller 200 , and a signal substation 300 .

[0025] A plurality of light sensors 100, wherein the plurality of light sensors 100 are respectively arranged on a plurality of dampers, and the plurality of light sensors 100 are used to detect the light intensity of the light outside the dampers;

[0026] A controller 200, the controller 200 is coupled to the light sensor 100, and the controller 200 is used to generate a damper opening instruction according to the light intensity of the plurality of dampers;

[0027] The signal substation 300 is arranged in the mine tunnel. The signal substation 300 is used to execute the damper opening instruction to control the corresponding damper to open, and to limit other dampers to be in a closed state.

[0028] Optionally, in an embodiment of the present invention, a plurality of damper opening and closing state sensors are further included, wherein the damper opening and closing state sensors are respectively arranged on a plurality of dampers, and the damper opening and closing state sensors are used to detect the opening and closing state of the dampers.

[0029] Optionally, in one embodiment of the present invention, a pneumatic assembly module is further included, and the pneumatic assembly module is arranged on the damper, and the pneumatic assembly module is used to control the opening of the damper.

[0030] Optionally, in one embodiment of the utility model, the pneumatic assembly module includes an air valve box, a cylinder, and a shuttle valve. The pneumatic assembly module is used to control the cylinder to push the damper to open by controlling the action of the solenoid valve in the air valve box, and automatically lock the other damper through the shuttle valve when one damper is opened.

[0031] The intelligent light-controlled switch for mining of the utility model is described in detail below through a specific embodiment.

[0032] Figure 2 This is a schematic diagram of the present embodiment. In this embodiment, a sensor is provided on the damper, and the sensor is connected to the signal substation through a signal line. When a pedestrian or a vehicle is detected to enter the stop area, the signal substation detects a state change and activates the control function of the damper. The pedestrian or vehicle illuminates the light-controlled switch with an external light source, and the signal substation receives a signal, issues a damper opening and closing instruction, starts to execute the opening instruction of one of the dampers, and restricts the other damper to a closed state, thereby realizing the switch control of the damper.

[0033] The functions of this embodiment include:

[0034] (1) Intelligent control function of light-operated switch.

[0035] The light-operated switch includes a light sensor and a controller. The light sensor is used to detect the intensity of external light. The controller is coupled to the light sensor and feeds back the detection results of the light sensor to the signal substation in real time to activate the damper control function. The signal substation recognizes and executes the opening instruction of one damper and limits the other damper to a closed state, thus realizing remote operation of the damper opening and closing. Figure 3 .

[0036] (2) Rapid feedback mechanism of light-controlled switch.

[0037] Usually, the underground lighting environment is more complex, and the dust concentration in the air is high. The control device of the damper based on the photosensitive signal has poor sensitivity and a long sensing time, resulting in slow traffic efficiency. The light sensor of the mine-used intelligent light-controlled switch uses the light intensity of the underground light as a benchmark. When external light sources such as pedestrians or vehicles illuminate the light-controlled switch, the light-controlled switch detects a change in light intensity, and then feeds the detection result back to the signal substation. The signal substation immediately controls the damper to open or close, thereby improving the efficiency of pedestrians and vehicles passing through, ensuring the safety of underground personnel, and ensuring underground ventilation safety. The circuit diagram of the mine-used intelligent light-controlled switch is shown in Figures 4(a) and 4(b).

[0038] (3) Tunnel automatic damper anti-accidental opening function.

[0039] The most basic requirement that dampers must meet is that each group of dampers must have no less than two dampers, and they cannot be opened at the same time; the mine tunnel automatic damper control system that uses mining intelligent light-controlled switches sets the damper opening condition to the two dampers in the tunnel being in the closed state at the same time. Pedestrians or vehicles illuminate the light-controlled switches with external light sources, and the signal substation is activated. The damper opening and closing instructions issued are effective, and the opening instruction of one of the dampers is executed, and the other damper is restricted to the closed state, so that the control system can reliably avoid the two dampers from opening at the same time, preventing the occurrence of airflow short-circuiting.

[0040] (4) Stable locking function of automatic damper in tunnel.

[0041] The pneumatic assembly system for controlling the opening and closing of the damper mainly includes a button box, an air valve box and a cylinder. The button box and the air valve box are installed near the damper, and the cylinder is installed on the first damper and the second damper. The opening and closing of the damper is mainly controlled by controlling the action of the solenoid valve in the air valve box to control the damper cylinder to push the damper to open and close; the pneumatic assembly system has an air circuit locking function, and the damper is combined with the pneumatic assembly system so that it also has a stable locking function; when one of the dampers is opened, the other damper is automatically locked by the shuttle valve.

[0042] (5) Infrared sensitivity adjustment function.

[0043] Figure 5 is a schematic diagram of the power module of this embodiment, as shown in Figure 5 As shown, the infrared remote control signal processing unit, photoresistor and control circuit in the intelligent light-controlled switch for mining are coupled via wires, and the intelligent light-controlled switch for mining receives the light emitted by the remote control to cause the resistance to change; the switching function is realized after the changed resistance reaches the reference value preset by the control circuit; the intelligent light-controlled switch for mining automatically controls the switch by sensing the intensity of light, and can adjust the sensitivity of the light sensor at the same time, so that the sensitivity can be adjusted to the optimal sensitivity to adapt, and has a wide range of applications and is worth promoting and applying.
