Description

Technical Field

[0001] This utility model relates to the field of monitoring and alarm technology, specifically to a personnel approach equipment alarm device. Background Technology

[0002] The working environment of coal mine roadway excavation faces is relatively limited, the excavation equipment is large in size, and there are many blind spots for the driver, resulting in a high number of accidents where personnel are crushed by the excavation equipment. Existing excavation equipment lacks personnel detection systems and cannot monitor the flow of personnel within the equipment's operating range in real time. To ensure safe production, personnel can only be assigned to guard the blind spots of the driver, which does not enable intelligent monitoring. The investment cost of electronic fences on the market is relatively high.

[0003] Therefore, to ensure personnel safety, a personnel approach equipment alarm device is provided. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a personnel approach equipment alarm device, including a remote control box. A mounting platform is installed on the front of the remote control box, and an ultrasonic radar ranging sensor is installed inside the mounting platform. A connecting wire is fixedly connected inside the ultrasonic radar ranging sensor. A voice and light alarm is installed on the front of the remote control box, and a connecting wire is fixedly connected inside the voice and light alarm. A battery is fixedly connected to one end of the connecting wire. A cover is installed on the top of the remote control box, and a warning sign is fixedly connected to the remote control box.

[0005] Through the above technical solution, by setting up an ultrasonic radar ranging sensor, the ultrasonic radar ranging sensor detects the working range. When personnel are detected, the ultrasonic radar ranging sensor will detect the signal and transmit it to the internal part of the voice and light alarm. The voice and light alarm will issue a voice and light alarm and stop the anchor conveyor unloading arm through the control box to ensure the safety of personnel. This device can effectively prevent personnel from accidentally entering dangerous areas and causing injury accidents, and improve the intelligent safety of coal mines.

[0006] As a further improvement to the above solution, the first connecting wire is disposed inside the mounting platform, and one end of the first connecting wire is fixedly connected to the inside of the battery.

[0007] Through the above technical solution, the connecting cable is placed inside the mounting platform, which protects it from interference or damage from the external environment. One end of the connecting cable is fixedly connected to the inside of the battery, ensuring the connection between the ultrasonic radar ranging sensor and the battery, enabling the sensor to work normally. Since the battery provides power to the sensor, this connection method ensures the stability of power transmission, thereby guaranteeing the normal operation of the entire alarm device.

[0008] As a further improvement to the above solution, the connecting wire runs through the cover, and the battery is located inside the remote control box.

[0009] With the above technical solution, the connecting wire runs through the cover. This design ensures that the cover can protect the internal components of the box while not affecting the connection function of the connecting wire, thus enabling the connection between the battery and the ultrasonic radar ranging sensor.

[0010] As a further improvement to the above solution, the cover is positioned above the battery.

[0011] As a further improvement to the above solution, a mounting bracket is fixedly connected to the rear end of the remote control box, and mounting holes are provided on the surface of the mounting bracket.

[0012] With the above technical solution, the remote control box is fixedly connected to the mounting bracket at the rear, which makes it easy to install the entire alarm device near the required equipment. The mounting bracket has mounting holes on its surface, which makes it possible to install the mounting bracket and the entire alarm device on other equipment or structures, making the installation more stable.

[0013] As a further improvement to the above solution, the number of mounting holes is set to several, and the several mounting holes are evenly distributed around the rear end surface of the mounting bracket in a symmetrical manner.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes an ultrasonic radar ranging sensor to detect the working area. When personnel are detected, the sensor transmits a signal to a voice and light alarm, which then issues an alarm and stops the unloading boom via a control box, ensuring personnel safety. This device effectively prevents personnel from accidentally entering dangerous areas and causing injuries, thus enhancing the intelligent safety management of coal mines.
