Description
Technical field
This utility model belongs to the technical field ensureing electric power safety work, a kind of safe fence with alarm function.
Background technology
Safety specifies " forbidding that operating personnel moves without authorization or removes fence ", but in real work, there is operating personnel ignore relevant regulations, privately remove, remove the situation of fence, cause live part and other dangerous spots not to be effectively isolated, leave potential safety hazard.
For solving this problem, there are many measure, scheme to be suggested, as utilized wireless senser, pulsed electron technology, the infrared technology such as liquidate, when operating personnel is near fence, sent warning signal.But these method high expensives, and easily because touching fence or equipment etc. by mistake, there is alarm by mistake.
Summary of the invention
The purpose of this utility model is the safe fence with alarm function providing a kind of simple in construction, low cost, reliability high.
The technical solution realizing this utility model purpose is:
A kind of safe fence with alarm function, it is characterised in that include several support foot rests, fence mesh, garter spring, the first switch, second switch, on and off switch, DC source and buzzer；Being provided with fence mesh between described adjacent two support foot rests, fence mesh is fixed on support foot rest by garter spring；At the connection cranse of described garter spring and support foot rest, each support foot rest is provided with second switch；Being positioned at the lower section of second switch, each support foot rest is disposed with buzzer, on and off switch, DC source, the bottom of each support foot rest is provided with the first switch.
Preferably, described DC source is sequentially connected with on and off switch, the first switch, buzzer, and the first switch is in parallel with second switch and is connected.
Preferably, described first switch and second switch all use normally closed push button switch, and on and off switch uses normally open push button switch.
Preferably, at the connection cranse of described garter spring and support foot rest, each support foot rest embeds second switch.
Preferably, the bottom of described each support foot rest embeds the first switch.
Preferably, described DC source uses rechargeable type lithium battery.
This utility model compared with prior art, its remarkable advantage:
(1) this utility model has the safe fence of alarm function only with buzzer, push-button switch, these cheap devices of DC source, relative to prior art, with low cost.
(2) this utility model has the safe fence employing circuit of alarm function very simply, and the buzzer of use, push-button switch, DC source are the most common, and relative to prior art, the maintenance after going wrong is the most simple and convenient.
(3) this utility model has the safe fence of alarm function state change reaction fence position and the change of connection in time by push-button switch, false alarm conditions will not occurs as utilizing the fence of the infrared technology such as liquidate, and accuracy is high.
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model has the safe fence of alarm function.
Fig. 2 is the electrical block diagram that this utility model has the safe fence of alarm function.
Detailed description of the invention
Embodiment 1:
As it is shown in figure 1, a kind of safe fence with alarm function, switch 4, second switch 5, on and off switch 6, DC source 7 and buzzer 8 including several support foot rests 1, fence mesh 2, garter spring 3, first；Being provided with fence mesh 2 between described adjacent two support foot rests 1, fence mesh 2 is fixed on support foot rest 1 by garter spring 3；At the connection cranse of described garter spring 3 and support foot rest 1, each support foot rest 1 is provided with second switch 5；Being positioned at the lower section of second switch 5, each support foot rest 1 is disposed with buzzer 8, on and off switch 6, DC source 7, the bottom of each support foot rest 1 is provided with the first switch 4.
As in figure 2 it is shown, described DC source 7 be sequentially connected with on and off switch 6, first switch 4, buzzer 8, the first switch 4 is in parallel with second switch 5 and is connected；Described first switch 4 and second switch 5 all use normally closed push button switch, on and off switch 6 to use normally open push button switch；I.e. first switch 4 and second switch 5 do not stress when acting on, and its button is always ejection state, and button stress is off state when being pressed, and when not stressing, button ejects is closure state；On and off switch 6 is pressed as closure state, ejects as off-state.
At the connection cranse of described garter spring 3 and support foot rest 1, each support foot rest 1 embedding second switch 5, the bottom of described each support foot rest 1 embeds the first switch 4.
Described DC source 7 uses rechargeable type lithium battery.
This utility model has an operation principle of the safe fence of alarm function:
When this utility model has the safe fence use of alarm function, press on and off switch 6 and be closure state, due to the bottom of the first switch 4 embedding support foot rest 1, the first switch 4 is under safe fence own wt effect, and i.e. first switch 4 that is pressed is off；If safe fence is raised, the first switch 4 ejections i.e. closure state, now, buzzer 8 can send out warning signal, reminds related personnel to be put down by fence immediately；Owing to second switch 5 is embedded at the garter spring 3 connection cranse with support foot rest 1, second switch 5, under the effect of garter spring 3, is pressed and is i.e. off；When garter spring 3 is opened, the second switch 5 i.e. closure state of ejection, now, buzzer 8 can send out warning signal, reminds related personnel's safe fence to be separated, is fixed by garter spring 3 the most at once.
This utility model has the safe fence of alarm function and has accuracy height, low cost, the advantage such as easy to maintenance, no matter overhauls workmen when moving or remove safe fence, all can start buzzer by the change of on off state in time, send warning signal.
