Manual fire hydrant button for optical fiber

Abstract

The invention discloses a manual fire hydrant button for an optical fiber. A first spring is arranged at the lower part of a touch panel of the button; a bottom shell is connected with a reset component through a second spring; a lug boss is arranged on the side, close to the touch panel, of the reset component; an inserted part is arranged on the side, close to the reset component, of the touch panel; when the touch panel manually moves downwards to get close to the bottom shell, the inserted part of the touch panel justly falls into the middle of two optical fiber clamping racks, the lug boss of the reset component enters into the inserted part of the touch panel, and then an optical path between the two optical fiber clamping racks is cut, a reset tool is used for running through a reset hole and pressing the reset component, so that the lug boss of the reset component is separated from the inserted part of the touch panel, and the touch panel moves upwards to reset under the effectof the first spring at the lower part of the touch panel. The function of manual fire hydrant button is realized in a pure optical manner so as to solve the problems such as anti-electromagnetic interference, moisture prevention and the corrosion, rust and verdigris prevention of copper wires, and the reliability performance is improved.

Description

technical field [0001] The invention relates to a button, in particular to a fiber optic manual fire hydrant button. Background technique [0002] With the rapid development of the economy and urban construction, the scale of the city continues to expand and the population continues to increase. As a result, the probability of various types of fires, especially major vicious fires, is increasing year by year. Timely and effective fire detection and alarm signals are reduced. It is one of the most effective means to reduce casualties and reduce economic losses in fire accidents; the most effective and direct way to extinguish fires on the spot is to spray fires, and it is essential to quickly start the water pump on the spot. The manual fire hydrant button is to start the pump on the spot. [0003] Traditional manual fire hydrant buttons are all electronically coded, because electronic components, copper wires are used for power supply and information transmission, and the el...

Problems solved by technology

[0003] Traditional manual fire hydrant buttons are all electronically coded. Because electronic components, copper wires are used for power supply and information transmission, the electronic components may become wet after a long time, causing the electronic components to short circuit and fail. In addition, the electronic components are prone to patina when they are wet. The long patina at the copper wire joint leads to false alarm or failure due to the change of contact resistance, which makes it impossible to manually start the water pump at the critical moment, resulting in the loss of life and property
