Description

Technical Field

[0001] The present application relates to the technical field of early warning devices, and more specifically, to a mechatronic early warning device. Background Art

[0002] The sound and light alarm, also known as the sound and light alarm, is designed to meet customers' special requirements for alarm loudness and installation location. It emits both sound and light alarm signals at the same time, and is an integrated early warning device in the alarm system of the electromechanical industry. The sound and light alarm (also known as the sound and light alarm) is a commonly used equipment in the fire protection field. It is an alarm signal device that sends relevant fire warning signals to people through sound and various lights. In the prior art, there is an explosion-proof sound and light alarm with a publication number of CN217762698U. After long-term use of the equipment, a large amount of dust falls on the outer wall of the shell, especially in outdoor environments, which affects the passage of light from the alarm light (light-emitting diode), resulting in a reduction in its brightness, and the warning effect cannot meet the requirements.

[0003] The document with the prior art publication number CN 219162779 U provides an audible and visual alarm, which drives the rotating shaft to rotate by rotating the rotating handle, and the rotating shaft drives the supporting rod to rotate, and the bristles on the outer wall of the supporting rod can clean the outer shell. When inspecting or assembling and disassembling the protective net of the equipment, one hand holds the bottom of the protective net, and when the thumb and index finger are used to apply force, the bottom of the elastic metal rod is deformed and moves toward one side of the outer shell, and then the protective net is pulled out upward, and the bottom of the protective net is separated from the card slot, so that the protective net is disassembled. When assembling the protective net, one hand holds the bottom of the protective net, and the bottom of the elastic metal rod is gathered together, and then the bottom of the elastic metal rod is inserted into the card slot. When the protective net is released, the bottom of the elastic metal rod returns to its original state, and the bottom of the elastic metal rod is stuck in the card slot.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the bristles need to be manually rotated when the device is used, so when the installation position is high, it will cause inconvenience in cleaning. At the same time, the current sound and light alarm uses a speaker to issue a sound warning, and once the speaker fails, it will not be able to issue a sound warning.

[0005] In view of this, we propose a mechatronic early warning device. Utility Model Content

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a mechatronic early warning device, including an audible and visual alarm, which includes a shell and a speaker, a rotating warning light group is fixed on the shell, the rotating warning light group includes a transparent cover fixed on the shell and a flash light rotatably arranged in the transparent cover, a cleaning mechanism is rotatably fitted on the outer wall of the transparent cover, the cleaning mechanism includes a U-shaped frame adapted to the transparent cover and connected to the flash light in transmission, a rag is fixed to the inner wall of the U-shaped frame, and a knocking warning mechanism is arranged between the shell and the U-shaped frame.

[0010] By adopting the above technical solution, the flashlight is rotatably arranged in the transparent cover to increase the range of the light warning area, and then the U-shaped frame is connected to the flashlight through a transmission, so that the U-shaped frame drives the rag to rotate and wipe the outer wall of the transparent cover to clean it. At the same time, the rotating U-shaped frame drives the knocking warning mechanism to operate to generate sound by knocking, so as to avoid the problem of no sound warning caused by damage to the speaker.

[0011] As an optional solution of the technical solution of the present application document, the knocking warning mechanism includes a dust shield, a plurality of springs distributed in an annular manner on the dust shield, a metal ball fixed on the spring, and a plurality of knocking sound tubes fixed on the shell.

[0012] By adopting the above technical solution, the dust shield can be used to block dust, sun and rain for the transparent cover. The dust shield is fixed on the top of the U-shaped frame, so that when the U-shaped frame rotates, the dust shield, the spring and the metal ball are driven to rotate, and the knocking sound tube is within the radius of the metal ball. When the metal ball rotates, the metal ball hits the knocking sound tube, and the knocking sound tube emits a warning sound. The spring is bent to avoid interference between the metal ball and the knocking sound tube, which causes the dust shield to be unable to rotate.
