Description

Technical Field

[0001] The utility model belongs to a mine signal lamp, in particular to an intrinsically safe mine signal lamp. Background Technique

[0002] The requirements for safety in comprehensive mining workface collection are getting higher and higher. When the supports in the fully mechanized mining workface move, it is very easy for on-site operators to be injured by falling objects or crushed by supports if they are not careful. Therefore, alarm information needs to be given when the supports move to prompt on-site personnel to pay attention to the changes in the dangerous environment.

[0003] At present, most of the signal lamps applied to underground coal mines have a single function, limited to the sound and light alarm function integrated on the controller. The function is too simple, and the installation position is not easy to observe, unable to meet the alarm information for functions such as support status, which greatly affects the personal safety of underground personnel.

[0004] To solve this problem, it is necessary to design and develop an intrinsically safe mine signal lamp. Summary of the Invention

[0005] In view of this, the purpose of the utility model is to provide an intrinsically safe mine signal lamp to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the following technical solutions are further adopted:

[0007] An intrinsically safe mine signal lamp includes a cover plate, a transparent cover is installed on the cover plate, a pressing plate is installed on the top of the transparent cover, and the four corners of the pressing plate are connected to the cover plate through long bolts;

[0008] An installation groove is opened in the middle of the upper part of the transparent cover, a buzzer is installed in the installation groove, and the buzzer is attached to the center position of the pressing plate;

[0009] Fixing parts are fixedly arranged on the transparent cover, the fixing parts are distributed around the buzzer, and several groups of control chips are fixedly installed around the fixing parts, and alarm lights are electrically installed on the control chips;

[0010] The control chips, the alarm lights are electrically connected to a peripheral protective connector.

[0011] As a further improvement of the utility model, a sound transmission hole is opened in the middle of the pressing plate at the position where the buzzer is located.

[0012] As a further improvement of the utility model, a sealing member is installed between the installation groove and the buzzer.

[0013] As a further improvement of the utility model, an installation plate integrally formed with the pressing plate is arranged on one side of the pressing plate, and the protective connector is fixedly installed on the installation plate.

[0014] The beneficial effects of the utility model are:

[0015] After being sealed with electronic sealant, the electrical unit of the present utility model is placed in a transparent PC housing and installed on the mounting bracket of the top beam of the bracket, which is convenient for observation. The lighting color and status of the signal lamp display different bracket states and are clearly visible at a distance of 20 m in the dark. It should have good stability, earthquake resistance, waterproof performance, long service life, be convenient for installation and use, and adapt to harsh environments.
