Abstract

Acoustic alarm level switch, comprise mark post, mark post is installed the first metal probe and the second metal probe that are arranged above and below, mark post top arranges controller, arrange water level detection circuit, driver and power supply in controller, install hummer outside controller, the first metal probe and the second metal probe are connected to the input end of water level detection circuit, the output terminal of water level detection circuit is connected to the input end of driver, and the output terminal of driver connects hummer.The utility model can monitor water level conditions, after water level rises above the warning line, and timely audible alarm.

Description

Acoustic alarm level switch
Technical field
The utility model belongs to hydraulic engineering field, specifically a kind of acoustic alarm level switch.
Background technology
At present, after water level rises above the warning line, need people's periodical inspection, the very first time can not obtain alarm, incur loss through delay process opportunity.
Utility model content
The utility model provides a kind of acoustic alarm level switch, in order to solve defect of the prior art.
The utility model is achieved by the following technical programs:
Acoustic alarm level switch, comprise mark post, mark post is installed the first metal probe and the second metal probe that are arranged above and below, mark post top arranges controller, arrange water level detection circuit, driver and power supply in controller, install hummer outside controller, the first metal probe and the second metal probe are connected to the input end of water level detection circuit, the output terminal of water level detection circuit is connected to the input end of driver, and the output terminal of driver connects hummer.
Acoustic alarm level switch as above, described mark post arranges fixed cover, the sidepiece mounting-fixing base of fixed cover.
Acoustic alarm level switch as above, the sidepiece of described controller arranges side stand, and side stand installs photovoltaic cell, and photovoltaic cell connects power supply.
Acoustic alarm level switch as above, described mark post arranges scale mark.
The utility model has the advantages that: the utility model can monitor water level conditions, after water level rises above the warning line, timely audible alarm.Utilize the electric conductivity of water, when water does not flood the second metal probe, resistance between first metal probe and the second metal probe is very large, and water logging is when crossing the first metal probe and the second metal probe, resistance between first metal probe and the second metal probe reduces rapidly, resistance variations between this first metal probe and the second metal probe is amplified by existing ripe water level detection circuit, then exports clear and definite level change.The output signal of water level detection circuit directly can be driven direct current hummer sounding after the power amplification of driver, thus remind people to note.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model; Fig. 2 is circuit diagram of the present utility model.
Reference numeral: 1 mark post 2 first metal probe 3 second metal probe 4 controller 5 fixed cover 6 holder 7 hummer 8 water level detection circuit 9 driver 10 photovoltaic cell 11 side stand.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Acoustic alarm level switch, as depicted in figs. 1 and 2, comprise mark post 1, mark post 1 is installed the first metal probe 2 and the second metal probe 3 be arranged above and below, mark post 1 top arranges controller 4, water level detection circuit 8, driver 9 and power supply are set in controller 4, hummer 7 is installed outside controller 4, first metal probe 2 and the second metal probe 3 are connected to the input end of water level detection circuit 8, the output terminal of water level detection circuit 8 is connected to the input end of driver 9, and the output terminal of driver 9 connects hummer 7.Utilize the electric conductivity of water, when water does not flood the second metal probe 3, resistance between first metal probe 2 and the second metal probe 3 is very large, and water logging is when crossing the first metal probe 2 and the second metal probe 3, resistance between first metal probe 2 and the second metal probe 3 reduces rapidly, resistance variations between this first metal probe 2 and the second metal probe 3 is amplified by existing ripe water level detection circuit 8, then exports clear and definite level change.The output signal of water level detection circuit 8 can directly be driven direct current hummer 6 sounding after the power amplification of driver 5, thus remind people to note.
Specifically, the mark post 1 described in the present embodiment arranges fixed cover 5, the sidepiece mounting-fixing base 6 of fixed cover 5.Holder 6 can be fixed on both sides, river course, by the position of adjustment mark post 1 with fixed cover 5, thus realizes the setting of alarm water level.
Concrete, the sidepiece of the controller 4 described in the present embodiment arranges side stand 11, side stand 11 is installed photovoltaic cell 10.Photovoltaic cell 10 powers to each device.
Concrete, the mark post 1 described in the present embodiment arranges scale mark.Scale mark can sound the depth of the water.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
