Description

Technical Field

[0001] This utility model relates to the technical field of geological disaster monitoring devices, and in particular to geological disaster monitoring devices for mines. Background Technology

[0002] Geological hazards in surface mines mainly include ground subsidence, ground settlement, ground fissures, landslides, collapses, and debris flows. These hazards are difficult to detect in advance using traditional manual investigations and conventional methods. They are characterized by their short duration of occurrence, inconspicuous signs of impending disaster, and suddenness.

[0003] The essence of geological disasters in surface mines is the vertical vibration or relative horizontal movement of the ground, which is similar to the situation when an earthquake occurs. Therefore, when searching for existing technologies, patents related to earthquake alarms are cited.

[0004] Chinese utility model patent authorization announcement number CN201312313Y discloses a broadcasting device with automatic earthquake alarm function, which consists of a broadcasting signal transmitter, an alarm switch circuit, and a vibration sensor. The core structure includes: a vibration sensor composed of suspended and fixed electrodes; a self-locking relay connecting the sensor and the alarm circuit; and an alarm switch circuit connected in parallel to the power switch. Vibration causes the suspended and fixed electrodes to make contact and conduct, triggering the self-locking relay to close, energizing the alarm circuit, and automatically activating the broadcasting system to emit an audible alarm.

[0005] Chinese invention patent application publication number CN101937607A discloses an earthquake alarm device, which consists of a sensing device and an alarm circuit. The sensing device includes a support frame on a base plate and a hanging magnet; the alarm circuit includes a power supply, a reed switch below the magnet, and an audible and visual alarm device. When an earthquake causes the magnet to shift, the power supply is activated, triggering the alarm. It combines rapid earthquake sensing capability with a warning effect.

[0006] Both published patents use ground vibration as a trigger mechanism, which connects the circuit and activates the alarm device. In mining operations, vibrations from explosive blasting and heavy machinery construction can cause false alarms in existing disaster monitoring systems. Therefore, there is an urgent need to develop a mine geological disaster monitoring device with vibration-resistant capabilities, which can effectively distinguish between construction vibrations and disaster signals through a unique mechanical structure, thereby avoiding false triggering of the monitoring device. Utility Model Content

[0007] In view of the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a geological disaster monitoring device for mines, thereby solving the problem that existing disaster monitoring systems are prone to false alarms.

[0008] To solve the above problems, the technical solution adopted by this utility model is: a mine geological disaster monitoring device, including a power supply, an insulated wire, a conductive cylinder, an audible and visual alarm, and a suspended conductive ball. The positive and negative poles of the power supply are fixedly connected to two identical conductive cylinders through the insulated wire, and the positive and negative poles of the audible and visual alarm are connected to two identical suspended conductive balls through the insulated wire. The suspended conductive balls are suspended inside the conductive cylinder through the insulated wire.

[0009] The conductive cylinder includes a cylindrical body and a circular cover. The cylindrical body is a hollow cylinder with a circular cover fixedly connected to its upper end. The circular cover has a hole at its center for an insulated wire to pass through.

[0010] The insulated wire includes an insulating layer and a conductor, with the insulating layer wrapping the conductor to form the insulated wire.

[0011] The working principle of this invention is as follows: When a geological disaster causes the conductive cylinder to tilt, the suspended conductive ball remains naturally drooping under the influence of gravity. When the conductive cylinder tilts to a certain angle, the suspended conductive ball contacts the inner wall of the conductor, forming a closed loop and triggering the audible and visual alarm to simultaneously emit sound and light alarms. Specifically: when both suspended conductive balls are in contact with their corresponding conductive cylinders, the power supply and the audible and visual alarm form a complete circuit, and the alarm is activated. The sensitivity of the device can be set by adjusting the length L; the larger the length L, the easier it is for the suspended conductive ball to contact the cylinder, and the higher the sensitivity.

[0012] Furthermore, the conductive cylinder is made of iron, copper, or aluminum.

[0013] Furthermore, the outer surface of the insulation layer has graduations. This facilitates accurate positioning when using wire clamps to fix and adjust the length L.

[0014] Furthermore, the conductor is made of copper or aluminum.

[0015] Furthermore, the mine geological disaster monitoring device also includes an insulating protective box and bar levels; the insulating protective box has a cuboid structure, with one bar level installed in both its length and width directions. The two vertical bar levels ensure the monitoring device is installed horizontally.

[0016] Furthermore, the mine geological disaster monitoring device also includes a wire clamp, which is arranged at the position where the insulated wire passes through the circular cover. The length of the insulated wire inside the conductive cylinder can be controlled by the wire clamp.

[0017] Compared with existing technologies, the beneficial effects of this solution are: 1. This device controls the length of the insulated wire through a clamp, allowing for flexible adjustment of the trigger distance between the suspended conductive ball and the conductive cylinder. This enables the setting of the trigger threshold based on the actual geological environment, avoiding false triggering caused by fixed sensitivity. 2. This device requires two independent conductive cylinders to be triggered simultaneously to activate the alarm, reducing false alarms caused by vibrations from explosive blasting or large-scale machinery construction during mining operations.

[0022] The following detailed description illustrates the specific implementation method:

[0023] Example 1

[0024] As attached Figure 1-3 As shown: A mine geological disaster monitoring device includes a power supply 1, an insulated wire 2, a conductive cylinder 3, an audible and visual alarm 4, and a suspended conductive ball 8. The positive and negative poles of the power supply 1 are fixedly connected to two identical conductive cylinders 3 through the insulated wire 2, and the positive and negative poles of the audible and visual alarm 4 are connected to two identical suspended conductive balls 8 through the insulated wire 2. The suspended conductive balls 8 are suspended inside the conductive cylinder 3 through the insulated wire 2.

[0025] The conductive cylinder 3 includes a cylindrical body 31 and a circular cover 32. The cylindrical body 31 is a hollow cylinder, and a circular cover 32 is fixedly connected to its upper end. The circular cover 32 has a hole at its center for the insulated wire 2 to pass through. The conductive cylinder 3 can be made of iron, copper, or aluminum.

[0026] The insulated wire 2 includes an insulation layer and a conductor. The insulation layer wraps around the conductor to form the insulated wire 2. The outer surface of the insulation layer has graduations. The material of the conductor is copper or aluminum.

[0027] The mine geological disaster monitoring device also includes an insulating protection box 5 and a bar level 6. The insulating protection box 5 has a cuboid structure, and a bar level 6 is installed in both the length and width directions of the insulating protection box 5.

[0028] The mine geological disaster monitoring device also includes a wire clamp 7, which is arranged at the position where the insulated wire 2 passes through the circular cover 32. The length of the insulated wire 2 inside the conductive cylinder 3 can be controlled by the wire clamp 7.

[0029] In this device, the conductive cylinder 3 is tilted at an angle The following relationship exists between the length L and the length L:

[0030]

[0031] The meanings of each letter in the relation are as follows:

[0032] Radius R: is the radius of the hollow part of the cylindrical body 31;

[0033] Radius r: is the radius of the suspended conductive sphere 8;

[0034] Length L: is the distance from the connection point between the insulated wire 2 and the suspended conductive ball 8 to the inner surface of the circular cover 32 of the conductive cylinder 3;

[0035] angle : is the tilt angle of the conductive cylinder 3.

[0036] The tilt angle of the conductive cylinder 3 is caused by ground movement due to geological disasters, which in turn causes the conductive cylinder 3 to tilt. When the conductive cylinder 3 tilts to a certain angle, the suspended conductive ball 8 inside contacts the conductive cylinder 3 under the action of gravity, the circuit is connected, and the audible and visual alarm 4 starts to work. The length of the insulated wire 2 inside the conductive cylinder 3 can be adjusted by using the wire clamp 7, thereby adjusting the sensitivity of the mine geological disaster monitoring device.

[0037] The positive and negative terminals of the power supply 1 are fixedly connected to the cylindrical bodies 31 of the two conductive cylinders 3 through insulated wires 2, respectively. The positive and negative terminals of the audible and visual alarm 4 are connected to the two suspended conductive balls 8 through insulated wires 2, and the conductive balls are suspended inside the conductive cylinder 3. The suspended conductive balls 8 hang naturally under the action of gravity and do not contact the inner wall of the conductive cylinder 3. The conductive cylinder 3 and the power supply 1 are fixed to the bottom of the insulating protective box 5, and the audible and visual alarm 4 is fixed to the top of the insulating protective box 5. The bar level 6 is used to calibrate the levelness of the device.

[0038] When a geological disaster occurs in a mine, the ground tilts, causing the conductive cylinder 3 to tilt as well. If the radius R of the hollow part of the cylindrical cylinder 31 is 5cm, the radius r of the suspended conductive ball 8 is 2cm, and the length L is fixed at 8cm by the clamp 7, then according to Table 1, when the tilt angle of the conductive cylinder 3 is greater than 30°, the suspended conductive ball 8 contacts the cylinder, and the audible and visual alarm 4 is activated immediately.
