Description
Technical field
The utility model is related to a kind of warning device, i.e., a kind of audible-visual annunciator for electric power overhaul fence.
Background technology
In the prior art, electric power overhaul fence be mainly used in power plant, Substation Electric Equipment maintenance, distribution maintenance,
Electrical test etc., can prevent staff from walking dislocation, or prevent other staff to be strayed into.But if moved, be difficult find or
Attention, influence safety in production are not caused.
Utility model content
The purpose of this utility model is directed to above-mentioned not enough and provides one kind and be installed on fence supports, can detect in time
By the mobile audible-visual annunciator for electric power overhaul fence.
Technical solution of the present utility model is：A kind of audible-visual annunciator for electric power overhaul fence, its feature exists
In including alarm carrier base, two supporting legs of the carrier base with folding, two supporting leg lower ends are with half with fence supports obvolvent
Circular trough, semi-circular groove involutory surface periphery may pass through one for fixed nylon adherent buckle, and carrier base inner bottom surface has and fence branch
The semicircle shrinkage pool of post column cap seated connection, there is alarm in the shrinkage pool chamber of carrier base upper surface, alarm is locked by hinge cover plate；Report
Alert device control circuit includes sensor U1, sensor U1 connecting triode Q1 base stages, triode Q1 emitter stages and relay K1,
K2, sound and light alarm part X1 are connected, and power supply VCC constitutes loop, triode by relay K1 nodes with sound and light alarm part X1
The colelctor electrode of Q1 is connected with button J2, switch J1.
The utility model has the advantages that：1st, support can adapt to the fence of diversified forms, can be installed in cradle top anti-
The functional devices such as mobile, shooting record.The resistance to movement functional module can sensitivity monitoring whether occur to be moved existing to body
As, and there is warning sound and light signal simultaneously.2nd, rationally, connection is reliable, meets use requirement for circuit structure.
Implementation method of the present utility model is described in further detail below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model use state structure diagram.
Fig. 3 is alarm control circuit theory diagrams.
Specific embodiment
Referring to Fig. 1,2,3, parts title is as follows：Carrier base 1, branch moves back 2, and fence supports 3, semi-circular groove 4 is semicircle recessed
Hole 5, shrinkage pool chamber 6, hinge cover plate 7, sensor U1, triode Q1, relay K1, relay K2, sound and light alarm part X1, power supply
VCC, button J2, switch J1.
Referring to Fig. 1,2,3, a kind of audible-visual annunciator for electric power overhaul fence, it is characterised in that including alarm support
Seat 1, two branch of the carrier base 1 with folding move back 2, and two branch move back 2 lower ends with the semi-circular groove 4 with the obvolvent of fence supports 3, semicircle
The involutory surface periphery of shape groove 4 may pass through one for fixed nylon adherent buckle, realize being connected.The inner bottom surface of carrier base 1 has and encloses
The semicircle shrinkage pool 5 of rail stanchion column cap seated connection, carrier base 1 has alarm in upper surface shrinkage pool chamber 6, and alarm passes through hinge cover plate
7 lockings；Alarm control circuit include sensor U1, sensor U1 connecting triode Q1 base stages, triode Q1 emitter stages with after
Electrical equipment K1, K2, sound and light alarm part X1 connections, power supply VCC constitute loop by relay K1 nodes with sound and light alarm part X1,
The colelctor electrode of triode Q1 is connected with button J2, switch J1.
Alarm is installed on carrier base 1, carrier base 1 is fixed on the top of fence supports 3 by nylon adherent buckle.Work as fence
Vibrations can be produced during by movement, shock sensor U1 sends high level trigger triode Q1 conductings, makes relay K1, K2 excitation,
Turn on two relay nodes.The conducting of its repeat circuit K2 nodes constitutes self-holding circuit, and no matter whether triode Q1 detects
Vibrations, can make the collimated excitations of relay K1 mono-.Power supply VCC constitutes back sound and light alarm part X1 by relay K1 nodes
Road, continuously sends out caution signal.After staff reaches the spot, by pressing button J2, loop is set to stop power supply, relay
K1, K2 are due to losing power supply, so that self-sustaining is failed, two relay K1, K2 losss of excitation, node is disconnected, and alarm portion X1 loops are broken
Open, stop alarm behavior.
It is described above, simply specific embodiment of the present utility model, various illustrations are not to reality of the present utility model
Matter Composition of contents is limited.
