Description

Technical Field

[0001] The utility model relates to the field of gold mining alarms, in particular to a portable alarm device used for gold mining. Background Art

[0002] A mine refers to a gold ore or gold mine, i.e., a collection of minerals containing sufficient gold for industrial use. Gold deposits worldwide are primarily found underground in the form of rock gold and placer gold, in addition to associated gold.

[0003] Gold mine alarm devices provide comprehensive, timely, and accurate safety alerts for gold mining operations, protecting miners and minimizing equipment losses. They primarily monitor and provide early warnings for hazardous conditions that may arise during the mining process, including leaks of toxic and harmful gases, excessive dust levels, fires, and roof collapses.

[0004] However, the gold mine alarm devices currently in use are difficult to move, and often many alarm devices are needed during mining. Moreover, the alarm devices cannot move with the depth of mining, making them extremely inconvenient to use.

[0005] In view of this, research and improvement are carried out on the existing problems, and a portable alarm device for gold mining is provided. The device has a reasonable structural design. The portable alarm device can detect changes in the concentration of harmful gases and dust in a timely manner during the gold mining process, and issue an alarm through the alarm and speaker to remind the operators to take corresponding safety measures. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content

[0027] Reference Figure 1-3 The utility model provides an embodiment: a portable alarm device for gold mining, comprising a shell 1 and a controller 10, an alarm 2 is provided at the upper end of the shell 1, a breathable net 4 is installed on the top of the alarm 2, a dust sensor 5 is installed on the outer wall of the alarm 2, an alarm indicator light 3 is provided on the surface of the shell 1, a rotary drill bit 6 is connected to the bottom of the shell 1, a speaker 12 is installed on the outer wall of the shell 1, a gas sensor 11 is installed on the inner side of the breathable net 4, a hydraulic rod 7 is provided inside the shell 1, one end of the hydraulic rod 7 is connected to a movable plate 8, and a drive motor 9 is installed on the surface of the movable plate 8.

[0028] In the present invention, the alarm 2 is fixedly mounted on the upper surface of the housing 1, and the alarm indicator light 3 is fixedly connected to the surface of the housing 1. Two alarm indicators 3 are provided. When the alarm 2 sounds, the two alarm indicators 3 provide visual warnings to the operator from different angles, thereby ensuring that the operator can quickly notice the alarm signal in the noisy gold mining environment. The provision of two alarm indicators 3 also improves system reliability. Even if one indicator fails, the other indicator can still operate normally, ensuring the effectiveness of the alarm system.

[0029] A rotary drill bit 6 is connected to the bottom of the housing 1 and is driven by a hydraulic rod 7 inside the housing 1. One end of the hydraulic rod 7 is connected to a movable plate 8, on the surface of which a drive motor 9 is mounted. The drive motor 9 can control the start, stop, and rotation speed of the rotary drill bit 6 according to the instructions of the controller 10, thereby achieving the fixation of the device.

[0030] Furthermore, the breathable mesh 4 is integrally connected to the top of the alarm 2. The gas sensor 11 is fixedly mounted on the inner side of the breathable mesh 4. The gas sensor 11 includes a carbon monoxide sensor, a hydrogen sulfide sensor, and a radon sensor. The dust sensor 5 is fixedly mounted on the outer wall of the alarm 2, enabling real-time monitoring of the concentration of harmful gases and dust in the gold mining environment. When the gas sensor 11 detects that the concentration of harmful gases exceeds a preset safety threshold, the alarm 2 immediately issues an audible and visual alarm and simultaneously sends a warning message to the operator via the controller 10. The provision of the gas sensor 11 ensures that operators receive timely warnings before inhaling harmful gases, allowing them to take appropriate safety measures and avoid potential health risks.

[0031] Specifically, dust sensor 5 detects dust concentration in the air. When the dust concentration is too high, alarm 2 will also trigger an alarm. Since increased dust concentration can cause explosions and other dangerous situations, the installation of dust sensor 5 is crucial to ensuring the safety of gold mining operations. Through real-time monitoring and timely alarms, this portable alarm device significantly improves the safety of gold mining operations and provides operators with a safer working environment.

[0032] Furthermore, the speaker 12 is fixedly mounted on the outer wall of the housing 1, the controller 10 is fixedly mounted inside the housing 1, the dust sensor 5 is electrically connected to the controller 10, the gas sensor 11 is electrically connected to the dust sensor 5, and the speaker 12 is electrically connected to the controller 10. The advantage is.

[0033] Furthermore, the hydraulic rod 7 is fixedly mounted inside the housing 1, the movable plate 8 is fixedly connected to the bottom of the hydraulic rod 7, the movable plate 8 is slidably connected inside the housing 1, the drive motor 9 is fixedly mounted on the lower surface of the movable plate 8, the number of the drive motors 9 is two, and the rotary drill bit 6 is transmission-connected to the bottom of the drive motor 9. Through the telescopic movement of the hydraulic rod 7, the movable plate 8 can drive the drive motor 9 to move up and down. When the drive motor 9 is started, the rotary drill bit 6 rotates accordingly, thereby fixing the work.

[0034] This portable alarm device works in conjunction with the drilling rig to ensure operator safety during the drilling process. When the gas sensor 11 or dust sensor 5 detects excessively high concentrations of hazardous gases or dust, the controller 10 immediately activates the alarm 2 and issues a warning through the speaker 12, reminding the operator to take necessary safety measures. This real-time monitoring and timely alarm mechanism not only improves operational safety but also provides a safer working environment for operators.

[0035] Working principle and usage process:

[0036] When the portable alarm device is operating at a gold mining site, dust sensor 5 first monitors the dust concentration in the air in real time. Once the dust concentration exceeds a preset safety threshold, dust sensor 5 transmits a signal to controller 10. Upon receiving the signal, controller 10 immediately activates alarm indicator 3 to issue a visual alarm and speaker 12 to sound an audible alarm, alerting on-site personnel to safety.

[0037] At the same time, the gas sensor 11 will continuously monitor harmful gases in the air, such as carbon monoxide, hydrogen sulfide and radon. If the concentration of harmful gases exceeds the standard, the gas sensor 11 will also transmit a signal to the controller 10, and the controller 10 will take corresponding alarm measures according to the gas type and concentration.

[0038] Under normal working conditions, the driving motor 9 drives the rotary drill bit 6 to fix the device.

[0039] The extension and retraction of the hydraulic rod 7 can drive the drive motor 9 and the rotary drill bit 6 to move downward. Driven by the drive motor 9, the rotary drill bit 6 can be driven to rotate, thereby fixing the device to the ground.

[0040] Through the above working principle, the portable alarm device of the utility model can effectively monitor the environmental conditions of the gold mine site and issue an alarm in time in dangerous situations, thereby ensuring the safety of workers and the normal operation of equipment.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
