Abstract
An automatic alarm for flood control comprises a acousto-optic alarm circuit which has a moving contact and a stationary contact; an armature is disposed between the moving and the stationary contact; one end of the armature is connected with a spring, the other end is connected with a power supply A; an electromagnet is disposed under the armature; one end of the lead of the electromagnet is connected with a water level detection block A, the other end of the lead of the electromagnet is in series connection with the power supply A, then is in in series connection with a water level detection block B. The utility model has the advantages of simple structure, in time alarm, economical and practibility.
Description
Technical field
The utility model relates to a kind of flood control autoalarm
Background technology
Reservoir relies on limnimeter to show at present, and observes the water level alarm line by the patrol personnel.Not only directly perceived inadequately but also be not easy to realize unmanned.
The utility model content
The technical matters that the utility model solves: a kind of flood control autoalarm is provided, has simple in structurely, report to the police in time economical and practical advantage.
The technical solution adopted in the utility model: flood control autoalarm, described alarm comprises a sound light alarming circuit, described sound light alarming circuit has a moving contact and stationary contact, between two sound contacts, be provided with armature, one end of armature is connected with spring, and the other end is connected with power supply A; Electromagnet is positioned at the armature below, and lead one end of described electromagnet connects water-level detecting piece A, is connected in series with water-level detecting piece B behind the lead other end serial connection power supply A of electromagnet.
The utility model compared with prior art by contacting of sound contact and armature is set, is reported to the police in time, has simple in structure, economical and practical.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
The flood control autoalarm, described alarm comprises a sound light alarming circuit, and described sound light alarming circuit has a moving contact 6 and stationary contact 7, is provided with armature 5 between two sound contacts, one end of armature 5 is connected with spring 10, and the other end is connected with power supply A; Electromagnet 4 is positioned at armature 5 belows, and lead one end of described electromagnet 4 connects water-level detecting piece A9, is connected in series with water-level detecting piece B8 behind the lead other end serial connection power supply A of electromagnet 4.
Principle of work: when water level was lower than derby A9, no current passed through in the electromagnet 4, under spring 10 pulling force effects armature 5 pull-ups and moving contact 6 was touched and closed, and green light 2 circuit are connected, and green light is bright; When water level arrived derby A9, electromagnet 4 circuit were connected, and electromagnet 4 produces magnetic fields, under under the action of a magnetic field, armature 5 being inhaled and stationary contact 7 touch and close, red light 3 circuit are connected, red light is bright, electric bell rings, and begins to report to the police.
