Example Embodiment

[0022] The present invention will be further described below with specific embodiments in conjunction with the drawings, see figure 1 :

[0023] For a mechanical alarm, a gear plate 5 is fixedly connected to the base 1 and a carrier 2 is rotatably supported. The planetary gear 6 fixed on the carrier meshes with the gear plate 5 for transmission. The cylinder motor 7 drives the planetary gear 6 to rotate and then drives the carrier around The base rotates, one side of the bracket is provided with an engine 4, and the other side is provided with a mechanical alarm device 3 driven by the main shaft of the engine 4. The main shaft of the engine 4 and the mechanical alarm device 3 are transferred through a gearbox 10. It also drives a generator 8 and an oil pump 9 that provides hydraulic power for the cylinder motor. The generator is connected to a battery 11, which is electrically connected to a controller 12. The controller controls the speed of the engine 4 or the output speed of t...

Abstract

The invention provides a mechanical alarm, and belongs to the technical field of machinery. The mechanical alarm solves the problem that an existing alarm is simple in structure and is unqualified for important alarm work. According to the mechanical alarm, a gear disk is fixedly connected with a base, a bracket is arranged on the base in a rotary supporting mode, a planet gear fixed to the bracket is in meshing transmission with the gear disk, an oil cylinder motor drives the planet gear to rotate so as to drive the bracket to rotate around the base, an engine is arranged on one side of the bracket, a mechanical alarm device driven by a main shaft of the engine is arranged on the other side of the bracket, and the main shaft of the engine is in switch connection with the mechanical alarm device through a gearbox. The mechanical alarm has the advantages that internal combustion engine drive or motor drive is adopted, and the mechanical alarm can be arranged on a transport vehicle to flexibly move, and can also be installed on a lifting platform or a tower or a roof; a loudspeaker mouth can rotate in a 360-degree mode, and can transmit alarm sounds in the fixed direction or rotate to transmit the alarm sounds in all directions.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a mechanical alarm. Background technique [0002] Large-scale alarms are important tools that can notify people when disasters and emergencies occur, and are directly related to people's life safety and property safety, so the quality of the alarm is critical. [0003] The structure of the current alarm is relatively simple, but it only has the function of sending out the alarm sound, the direction of the horn is fixed, and the sound wave transmission distance is average, so some important alarm tasks cannot be well satisfied. Contents of the invention [0004] The purpose of the present invention is to provide a mechanical alarm suitable for military, civil defense and power stations, etc., which belongs to a kind of alarm. On platforms, towers or roofs, the loudspeaker horn can be rotated 360 degrees, directional or rotated to spread the alarm sound around. [0005] The p...
