Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, a coal mine communication cable disconnection warning device comprises a communication cable 1 and a safety rope 2 attached to the communication cable, wherein any section of the communication cable 1 is respectively fixed with two cable fixing clamps 3, one cable fixing clamp 3 is fixed with a disconnection warning component 4, the other cable fixing clamp 3 is fixed with a connecting plate 5, one end of the safety rope 2 is connected to the disconnection warning component 3, the other end of the safety rope is fixed on the connecting plate 5, and the safety rope 3 is used for triggering the disconnection warning component when the communication cable is scratched and bumped; the broken line alarm assembly 4 mainly comprises a box body 6, a box cover 7 fixed on the box body and an opposite type photoelectric switch 8 installed in the box body, a fixed plate 9 is fixed in the box body 6, two sides of the fixed plate 9 are respectively provided with a guide rod 10, the end part of each guide rod 10 is provided with a limiting plate 11, a movable plate 12 is installed on each guide rod 10, a reset spring 25 is further installed on each guide rod 10, a through hole is formed in the center of the fixed plate 9, a safety rope 2 penetrates through the through hole and is fixed on the movable plate 12, the emitting end of the opposite type photoelectric switch 8 is fixed on the movable plate 12, the receiving end of the opposite type photoelectric switch 8 is fixed on the fixed plate 9, one side of the opposite type photoelectric switch 8 is provided with a first connecting plate 13 and a second connecting plate 14, the first connecting plate 13 is fixed on the movable plate 12, the second connecting plate 14 is fixed on the, the end part of the second connecting plate 14 is provided with a control rod 16 through a pin shaft, a torsional spring is arranged on the pin shaft, the correlation photoelectric switch 8 is connected and communicated with a coal mine lower computer, and an audible and visual alarm is arranged on the coal mine lower computer.
When the communication cable disconnection warning device is used, cable fixing clamps are respectively arranged at two ends of an overhead section of the communication cable, then the disconnection warning component 4 and the connecting plate 5 are respectively arranged on the two cable fixing clamps, and the safety rope is arranged between the disconnection warning component 4 and the connecting plate 5, so that the safety rope is attached to the communication cable. The communication cable 1 and the safety rope 2 are fixed by a plurality of fixing rubber sleeves 17. Utilize fixed gum cover to fix the safety rope, can guarantee that safety rope and communication cable closely laminate, also can guarantee safe taut. When normal, the correlation photoelectric switch can normally generate signals. When the communication cable is pulled or scratched, even if it is scratched, the safety cord is also pulled or scratched. One end of the safety rope is fixed, and the other end of the safety rope is fixed on the movable plate. When the drawn or scraped movable plate moves along the guide bar, the first connecting plate 13 is moved toward the second connecting plate 14. And because the pin shafts of the stop plate and the control rod are both provided with torsional springs, the torsional springs enable the stop plate to rotate towards the direction far away from the first connecting plate 13, and the torsional springs enable the control rod to rotate towards the direction far away from the second connecting plate 14. Thus, when the first connecting plate 13 approaches the second connecting plate 14, the blocking plate and the control rod are attached to the center, and are not inclined to either side. At this time, the blocking plate is gradually in a horizontal state, so that the opposite type photoelectric switch 8 is blocked, the signal is interrupted, and an alarm signal is generated. With this configuration, the communication cable can be warned at the initial stage of being scratched with high sensitivity.

In order to ensure that the alarm continues after the cable is broken and even the safety rope is broken, a limiting rod is adopted for control. When the cable breaks, even the safety rope breaks, the distance between fly leaf and the fixed plate is in the minimum position, and at this moment, the gag lever post cartridge is in spacing blind hole. Due to the effect of the wedge-shaped control block 24, when the limiting rod is inserted into the limiting blind hole, the wedge-shaped control block 24 is just clamped on the annular locking groove 20 of the limiting rod, the limiting rod cannot be pulled out, the blocking plate continuously shields the correlation type photoelectric switch 8, and then a continuous alarm signal is generated.
In addition, an adjusting rod 27 is fixed at the middle of the movable plate 12, the adjusting rod 27 is inserted into the through hole, an adjusting nut 26 is installed at the end of the adjusting rod 27, and the safety rope 2 is fixed on the adjusting rod 27. The sensitivity of the device can be adjusted by adjusting the rod, and the adjustment can be freely carried out as required.
The specific alarm method comprises the following steps: the safety rope is attached to the communication cable, when the communication cable is normal, the signal of the correlation type photoelectric switch is normal, and an alarm signal is not generated; when the communication cable is pulled or scraped, even when the cable is broken, the movable plate is pulled by the safety rope and is close to the fixed plate, the control rod pushes the blocking plate to be in a horizontal state, the blocking plate shields the opposite type photoelectric switch, the signal of the opposite type photoelectric switch is interrupted, and the lower computer of the coal mine sends an alarm signal through the alarm.
