Abstract
The utility model provides a kind of well lid autoalarm, including hydraulic lift and warning device, warning device is arranged on hydraulic lift, warning device includes being provided with warning circuit in shell, shell, and warning circuit includes being serially connected power supply, the light-emitting device for loop, sound-producing device and flip-over type switch, flip-over type is switched off when the spring column of flip-over type switch is pushed, and flip-over type switch closure when spring column rises, spring column is stretched out at the opening of shell.When well lid is lost or damages, hydraulic lift rises warning device, and flip-over type switch closure, luminous and sounding type device is alarmed.The device changes traditional passive alarm, actively carries out early warning, improves security, and simple in construction, easy for installation, can be widely popularized and use.
Description
Technical field
The utility model is related to a kind of well lid autoalarm under loss or damaged condition.
Background technology
Well lid is lost or breakage is one of the problem of making China's municipal administration personnel's headache, caused by well lid is lost or damages
Casualties it is also of common occurrence.Current well lid is lost or the damaged main inspection by patrol officer is found, and well lid is being lost
Lose or the very first time of breakage will result in great potential safety hazard, how to carry out early warning in the very first time, be to face at present
Subject matter.
Utility model content
In order to solve problem present in background technology, the utility model provides a kind of well lid autoalarm, should
Warning device can carry out early warning in the very first time that well lid is lost or damages, and ensure passerby's safety.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of well lid autoalarm, including hydraulic lift and warning device, warning device are arranged on hydraulic pressure liter
On falling unit, it is characterised in that warning device includes being provided with warning circuit in shell, shell, and warning circuit includes mutual string
Join center of top in power supply, the light-emitting device for loop, sound-producing device and flip-over type switch, shell and be provided with opening, flip-over type
Switch has spring column, and flip-over type is switched off when spring column is pushed, and flip-over type switch closure when spring column rises, spring column is opened from shell
Stretched out at mouthful.
Under the elevating lever that the lowering or hoisting gear includes the sleeve of contained liquid and is arranged in sleeve, nature, lifting
Bar stretches out from sleeve, under stress, in elevating lever retraction sleeve.
The shell is transparent.
The sound-producing device is loudspeaker.
The light-emitting device is bulb.
The autoalarm is fixed on inspection shaft inwall, and well lid is pressed in the spring column of the autoalarm.
The liquid is hydraulic oil.
The beneficial effects of the utility model are：
1) device changes the defect of other device passive protections, and danger signal is spread out of, and implements initiative alarming；
2) electrical equipment in the device only has loudspeaker and bulb, and power consumption is low, in well lid normal work, and circuit, which is in, to be disconnected
State, saves the energy；
3) it is easy for installation, only need to secure the device to inspection shaft inwall when using, only needed to when changing battery by
Warning circuit takes out replacing from shell；
4) have a wide range of application, available for various inspection shafts；Automaticity is high, and lifting is not hurted sb.'s feelings slowly, and prompting range is wide, can
5-10m is reached, provided with hand switch, manual-lock if necessary.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the structural representation of autoalarm described in the utility model；
Fig. 2 is the detail drawing of warning circuit in Fig. 1；
Fig. 3 is the use state figure of autoalarm described in the utility model；
Fig. 4 is the alarm condition figure of autoalarm described in the utility model.
Embodiment
Explanation and embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, a kind of well lid autoalarm, including hydraulic lift and warning device, warning device is set
Put on hydraulic lift, lowering or hoisting gear includes being provided with elevating lever 3, nature in the sleeve 1 of contained liquid 2, sleeve 1
Under, by hydraulic action, elevating lever 3 stretches out from sleeve 1.Warning device includes being provided with alarm electricity in transparent outer cover 4, shell 4
Road 5.Warning circuit 5 is as shown in Fig. 2 including power supply 7, light-emitting device 8, sound-producing device 6 and flip-over type switch 9, power supply 7, luminous
Device 8, sound-producing device 6 and flip-over type switch 9 are serially connected as loop, and center of top is provided with opening in shell 4, and flip-over type is opened
The spring column for closing 9 is stretched out at opening.Specifically, sound-producing device 6 is loudspeaker, light-emitting device is bulb.
Band spring switch 9 includes spring column and is arranged on the closure switch of spring column bottom, and spring column is moved down under stress,
Remain closed switch to open, at this time whole warning circuit 5 disconnects；When band spring switch 9 in the raw when, spring column rise,
Closure switch are closed, at this time whole warning circuit formation loop, and light-emitting device 8 and sound-producing device 6 are operated, and start alarm.
The use of the warning device such as Fig. 3,4 so, under normal condition, the sleeve 2 of warning device is fixed on well inwall,
Well lid 10 is pressed on warning device, due to being acted on by well lid pressure, in the retraction sleeve 1 of lifting column 3, and flip-over type switch 9 is depressed,
Warning circuit 5 disconnects；When the sounding of well lid 10 is moved, the pressure dump at the top of warning device, lifting column 3 stretches out from sleeve 1,
Flip-over type switch 9 is closed, and light-emitting device 8 and sound-producing device 6 are operated, and luminous and sounding type is alarmed.Now people's sense on well lid periphery
By sound and light alarm, the inspection shaft of danger is left, autoalarm plays active defense effect.
It will be recognized by those skilled in the art, can be to above-mentioned on the premise of without departing from protection scope of the present invention
Embodiment carries out various modifications, change and combined, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
