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, detecting device is due to chronic sun exposure night dew, corrosion in addition, and serviceable life is not long.
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, spring pressuring plate is fixing on the controller, backstay can move horizontally in spring pressuring plate, the end of backstay is provided with depression bar, spring fit backstay, one end linking springs compressing tablet, the other end is fixing on the controller, in controller, water level detection circuit is set, driver and power supply, outside controller, hummer is installed, 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, 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.
Acoustic alarm level switch as above, described mark post is that stainless steel is made, and mark post upper end is provided with pilot hole.
Acoustic alarm level switch as above, described backstay and depression bar adopt hinged cooperation.
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; Fig. 3 is the sectional structure schematic diagram of the utility model controller; Fig. 4 is the structural representation of the utility model mark post.
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 12 spring 13 depression bar 14 spring pressuring plate 15 backstay 16 pilot hole.
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, spring pressuring plate 14 is fixed on controller 4, backstay 15 can move horizontally in spring pressuring plate 14, the end of backstay 15 is provided with depression bar 13, spring 12 fit backstay 15, one end linking springs compressing tablet 14, the other end is fixed on controller 4, water level detection circuit 8 is set in controller 4, driver 9 and power supply, 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, 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.
