Abstract
The utility model relates to a mechanical sound alarm which is suitable for being used for wide rural areas. The mechanical sound alarm which is suitable for being used for wide rural areas is composed of a signal receiving device, a control circuit, and a wind sounding device. The signal receiving device is a microswitch which is controlled by a pull rod and a pull ring. The control circuit is that a minitype direct current blower is controlled by controlled silicon. The minitype direct current blower just faces to the wind sounding device to send out wind to send out sound to alarm. The mechanical sound alarm which is suitable for being used for wide rural areas has simple and compact structure, small volume, light weight, simple manufacture, low cost, and reliable alarm performance. The mechanical sound alarm which is suitable for being used for wide rural areas is suitable for the anti-theft alarm of the places of wide rural area houses, poultry houses, and pig houses, etc.
Description
The utility model is a kind of simple and easy mechanical sonic alarm that use in vast rural area that is suitable for.
Current comprehensive approach to the management of social problems is unsatisfactory; the theft phenomenon happens occasionally; the stolen property phenomenon in especially vast rural area is quite serious; press for a kind of burglar alarm, the various alarms of Chu Shouing are of a great variety in the market, but the electronic circuit more complicated of most alarms; production requirement is higher; price is more expensive, and general user and vast farmers are difficult to bear, and wishing has a kind of small-sized, inexpensive, easy alarm to protect their property not stolen.
The purpose of this utility model provides a kind of small-sized, simple in structure, cheap, and the mechanical sonic alarm of dependable performance is to adapt to the needs of vast rural area theft protection.
The utility model is achieved in that this alarm is by signal receiving device, control circuit and wind song Chinese percussion instrument constitute, signal receiving device is made up of microswitch, pull bar and draw ring, control circuit is that a SCR control minisize dc fan blower and power supply are formed, and this fan blower is aimed at the air-supply of wind song Chinese percussion instrument and sent audible alarm.
This alarm is simple in structure, compact, volume is little, in light weight, install easily, circuit is simple, and is cheap, the warning dependable performance is applicable to have wide range of applications the burglar alarm in places such as vast rustic home, poultry, pig house, fish pond.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is mechanical sonic alarm structural drawing;
Fig. 2 is the structural drawing of signal receiving device;
Fig. 3 is control circuit figure;
Fig. 4 is the structural drawing of wind song Chinese percussion instrument
With reference to Fig. 1, this alarm is by signal receiving device 1, and control circuit 2 and wind song Chinese percussion instrument 3 constitute.Signal receiving device 1(is as shown in Figure 2) form by microswitch 4, pull bar 5 and draw ring 6, they are contained in the independently rectangular box 15, wherein the normal opened contact of microswitch 4 causes on the box body with lead, as signal contact 16, the fulcrum of pull bar 5 is fixed on the box 15, the pulling draw ring makes pull bar depress microswitch, at this moment the normal opened contact closure.Be that rope or nylon wire are arranged on the draw ring; their termination be fixed on the protected housing window place such as poultry, pig house or across must through passage on; rope can be provided with many, multi-direction, realizes the omnibearing anti-theft warning, when the stranger touches, bumps, draws signal can take place.Control circuit 2(is as shown in Figure 3) by the normal opened contact of microswitch 4, be the signal contact 16 control silicon controlled control utmost points, by silicon controlled collector control minisize dc electric current 8, and adopt two supply lines, one the tunnel is No. 1 dry cell power supplies of four joints, another road is external ac rectifying power source power supply, isolates with diode (D1 D2) between two circuits, and power supply is controlled by K switch.Load onto fan blade 7 and Fan casing 14 from making the minisize dc fan blower by DC micromotor 8, this fan blower is aimed at air inlet 10 air-supplies of wind song Chinese percussion instrument and is sent audible alarm.Wind song Chinese percussion instrument 3(such as Fig. 4 show) be a round, in have resonator 9, one ends and have the import 11 of blast inlet 10 and air nature.End has gas vent 12 in addition.Control circuit 2, minisize dc fan blower, wind song Chinese percussion instrument 3 and dry cell E install concentratedly in a little square box 17, half of box placed No. 1 dry cell of 4 joints, fan blower and wind song Chinese percussion instrument are fixed on the metal erecting frame 18, box is provided with external power supply jack 19 and outer signal jack 20, and these jack 20 usefulness leads are connected with the signal contact 16 of signal receiving device 1, during use, square box is placed on operator on duty's bedside or the table, and signal receiving device 1 is placed on antitheft on-the-spot shelter.Its course of work is as follows: the K that closes a switch earlier, when line or rope when pulled, the normal opened contact closure of microswitch, the controllable silicon conducting makes direct current generator 8 running and wind song Chinese percussion instrument 3 is blowed in air blast, sends howling to report to the police, and wakes the operator on duty up and rushes towards the scene.This alarm is simple in structure, makes simple and easyly, with low cost, is suitable for vast rural area and uses.
