Description

Technical Field

[0001] The utility model relates to the technical field of mine helmets, in particular to a monitoring helmet for mines. Background Art

[0002] Safety helmets can prevent miners' heads from being injured, such as being hit by gravel or falling objects. Helmets can also strengthen the support of miners' heads, reduce the burden on neck muscles, and help miners work for a long time. In order to improve the safety of mines and understand the working conditions in mines, existing helmets are equipped with cameras to monitor the real-time status of underground work. In addition, now there are also lighting lamps installed on the helmets to assist workers in lighting in mines.

[0003] However, the existing safety helmets still have the following two problems:

[0004] 1. The safety monitoring of workers depends on the camera to monitor the real-time status underground. However, relying only on monitoring the real-time status to ensure the safety of workers cannot confirm the status of workers in case the camera is damaged.

[0005] 2. The irradiation direction of the lighting lamp installed on the helmet is fixed and cannot be adjusted, which is not convenient for use in other situations of workers. Summary of the Utility Model

[0006] According to the above existing technical problems, the utility model provides a monitoring helmet for mines, which is characterized by including a helmet body, a mounting rod, an adjustable lighting lamp, a camera, a protective shell, a circuit board, a control unit, a harmful gas monitoring sensor, and an acceleration sensor.

The mounting rod is provided with an adjustable lighting lamp. The protective shell is installed on the rear side of the helmet body. The circuit board is installed inside the protective shell. The control unit is provided on the circuit board. The harmful gas monitoring sensor and the acceleration sensor are installed on the protective shell.

[0007] The adjustable lighting lamp consists of a lighting lamp, a connecting rod, and a universal ball. The lighting lamp is connected to the universal ball through the connecting rod, and the universal ball is installed on the mounting rod.

[0008] The control unit consists of a controller, a power supply module, and a Bluetooth wireless communication module. The controller is respectively connected to the power supply module and the Bluetooth wireless communication module, and the controller is electrically connected to the harmful gas monitoring sensor and the acceleration sensor respectively.

[0009] Specifically, the power supply module is a battery, which is electrically connected to other electronic components to supply power to the electronic components.

[0010] Specifically, the harmful gas monitoring sensor is a sensor for detecting methane gas.

[0012] Advantages of the present utility model:

[0013] In the present utility model, a control unit is installed on the helmet.

According to the received signal strength indication (RSS) positioning technology, the position information of the staff is judged, and corresponding emergency treatment is carried out to ensure the safety of the workers underground. The harmful gas monitoring sensor is used to detect the content of harmful gases such as methane and transmit it to the management platform. In addition, the acceleration sensor is used to detect the number of steps of the operator, and the safety state of the human body is analyzed through the number of steps.

[0014] The adjustable lighting lamp designed in the present utility model is connected to the mounting rod through a universal ball, which is convenient for the worker to adjust the irradiation direction of the lighting lamp during use to meet more usage requirements. Description of the drawings
