The flood control alarm
Technical field
The utility model relates to a kind of flood control alarm.
Background technology
In recent years, flood frequently takes place, and big flood brings very big loss for huge numbers of families and country, serious harm people's the person and property safety.And existing mostly by manually checking flood situation, the measurement warning device is also arranged, but structure more complicated all, cost is higher.
The utility model content
The purpose of this utility model provides a kind of flood control alarm, can in time remind flood damage to be about to take place, and guarantees people's safety.
The utility model adopts following technical proposals: a kind of flood control alarm, comprise that the bottom is provided with water storage device, relay, warning device and the power supply of water inlet, be provided with float, stationary installation and the inner connecting rod that is provided with thereof in the water storage device, wherein the stationary installation bottom communicates with water storage device, float is fixed on the connecting rod bottom, the connecting rod top is connected with the contact at the outer top of stationary installation, and the contact of relay is fixed on directly over the contact, is connected with power supply behind the relay series connection warning device.
Described water storage device side is fixed with support, and described contact and stationary installation all are connected and fixed with support.
Described stationary installation is up-thin-low-thick ampuliform device, and its top and bottom are hatch frame.
The utility model can carry out alarm when being about to big flood takes place, make people know that in advance flood is about to go up, and in time shifts masses' property, does the corresponding precautionary measures, reduces the loss that flood damage causes greatly; The utility model design is peculiar, simple in structure, practical, and cost is low.
