In FIGS. 1-3: the instrument panel 1, the thread bushing 2, the spring hinge 201, the asbestos heat insulation layer 202, the protective cover 3, the air inlet 301, the air cooler 302 and the temperature sensor 303.
Detailed Description
Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
referring to figures 1-3 of the drawings,
the embodiment provides a pair of automatic change instrument and meter protection and use overheat protection device, including panel board 1, 1 top outside fixed mounting of panel board has thread bush 2, there is spring hinge 201 in 2 left sides of thread bush through bolt fixed mounting, thread bush 2 closely laminates with 1 contact surface of panel board has asbestos insulating layer 202, there is safety cover 3 in spring hinge 201 left side through bolt fixed mounting, 3 surperficial outside trompils of safety cover are provided with fresh air inlet 301, 3 inside bolt fixed mounting that pass through of safety cover have air-cooler 302, 3 inside bolt fixed mounting that pass through of safety cover has temperature sensor 303.
Furthermore, the protective cover 3 is rotatably connected with the instrument panel 1 through the spring hinge 201, and a user opens the protective cover 3 through the spring hinge 201 to observe the instrument panel 1.
Further, the air inlet holes 301 are uniformly arranged on the surface of the protective cover 3 in a circular ring shape, and a required air source is provided for the air cooler 302 through the air inlet holes 301.
Further, temperature sensor 303's signal output part is signal connection with the signal receiving end of air-cooler 302, detects the temperature of instrument panel 1 through temperature sensor 303, and with signal of telecommunication transmission for air-cooler 302 when panel board 1 detects when exceeding rated value and cool down, with the heat on panel board 1 surface and outside air rapid contact, reach automatic rapid cooling's effect.
Further, the surface of the protective cover 3 is provided with a control switch which is matched with the temperature sensor 303 and the air cooler 302 for use, so that the temperature sensor 303 and the air cooler 302 can be freely turned on and off through the control switch, and intelligent and automatic overheating protection of automatic instruments and meters is realized.
Furthermore, the instrument panel 1 is connected with the threaded sleeve 2 through threaded engagement, the asbestos heat insulation layer 202 is tightly attached to the contact surface of the threaded sleeve 2 and the instrument panel 1, the asbestos heat insulation layer 202 has the characteristic of low heat conductivity coefficient, and the effect of effectively preventing heat generated by the instrument panel 1 from being rapidly transferred to the inner layer of the threaded sleeve 2 is achieved.
