As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas cabinet cabinet position described in the utility model pressure out-of-limit alarming device;
Fig. 2 is the warning circuit schematic diagram of gas cabinet cabinet position described in the utility model pressure out-of-limit alarming device.
Wherein: 1 is gas cabinet, 2 is air bag, and 3 is link, and 4 is slideway, and 5 is piston, and 6 is balancing weight, and 7 is position limit switch LS1, and 8 is alarm, and 9 is position limit switch LS2, and 10 is position limit switch LS3.
Embodiment
For making the technical solution of the utility model and advantage clearly, below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described.
As depicted in figs. 1 and 2, a kind of gas cabinet cabinet position of the present utility model pressure out-of-limit alarming device, comprise the piston 5 be arranged in gas cabinet 1 and the balancing weight 6 be arranged on outside gas cabinet 1, balancing weight 6 is connected on piston 5 by link 3, be provided with in the below of balancing weight 6 three respectively with balancing weight 6 with the use of position limit switch, i.e. position limit switch LS1, position limit switch LS2 and position limit switch LS3.Position limit switch LS1, position limit switch LS2 and position limit switch LS3 from up to down distribute in FIG successively, and corresponding reference character is sequentially 7,9 and 10.Each position limit switch is installed in Same Alarm circuit, described position limit switch between two with described warning circuit with the use of.Described warning circuit comprises power supply and auxiliary reclay KA1, auxiliary reclay KA2, auxiliary reclay KA3 and auxiliary reclay KA4; The coil of position limit switch LS1 and auxiliary reclay KA1 is in series to the coil of series connection, position limit switch LS2 and auxiliary reclay KA2 to the coil of series connection, position limit switch LS3 and auxiliary reclay KA3, is connected in parallel on described power supply afterwards respectively; The normally opened contact KA1-1 of auxiliary reclay KA1, auxiliary reclay KA2 normally opened contact KA2-1, auxiliary reclay KA3 normally opened contact KA3-1 are in parallel after connecting between two, afterwards with the coils connected in series of auxiliary reclay KA4 at the two ends of described power supply; Auxiliary reclay KA4 normally opened contact KA4-1 and alarm 8 are connected in the two ends of described power supply.
In above-mentioned three position limit switches, when having at least two position limit switches to connect under the effect of balancing weight 6 simultaneously, warning circuit all sends warning, this had both completed the warning of cabinet position when reaching preset upper limit of gas cabinet 1, also largely avoid the generation of the phenomenon of not reporting to the police caused of being failure to actuate of false alarm phenomenon that the misoperation because of single position limit switch causes and/or single position limit switch, improve reliability and security used in this application.
The application also comprises one for the slideway 4 of spacing described balancing weight 6, and described slideway 4 is arranged on the outer side wall of gas cabinet 1.Each position limit switch is installed in slideway 4, and the transverse section of slideway 4 is curved.Wherein, when gas cabinet 1 be equipped with balancing weight 6 with the use of slideway time, if gas cabinet 1 be Wiggins gas holder, above-mentioned each position limit switch can be arranged on gas cabinet 1 self outfit with balancing weight 6 with the use of slideway in.
Described link 3 is wire rope.Each position limit switch is that yi word pattern is vertically arranged, and two of lie farthest away position limit switches, the height being vertically highly less than balancing weight 6 namely between position limit switch LS1 and position limit switch LS3.
Before use, above-mentioned three position limit switches are arranged on the correct position of slideway 4 lower end according to actual demand.After energising, along with increasing of gas-storing capacity in gas cabinet 1, piston 5 moves, balancing weight 6 synchronously moves down simultaneously, when piston 5 moves to the upper limit position preset, after balancing weight 6 triggers any two in three position limit switches or three position limit switches, the circuit ON at alarm 8 place, and then the alarm signal sending that cabinet position reaches preset upper limit.Such as, in the present embodiment, position limit switch LS2 in use catastrophic failure, when piston 5 moving to the upper limit preset, when balancing weight 6 triggers position limit switch LS1 and position limit switch LS3 simultaneously, the coil of auxiliary reclay KA1 and KA3 obtains electric, thus the normally opened contact KA1-1 of auxiliary reclay KA1 closes, the normally opened contact KA3-1 of auxiliary reclay KA3 closes, the coil of auxiliary reclay KA4 obtains electric, and then the normally opened contact KA4-1 of auxiliary reclay KA4 closes, alarm 8 electricly must send caution sound, thus remind personnel's gas cabinet 1 cabinet position, post to arrive the upper limit position preset, to make relevant treatment in time.This not only can complete the warning of cabinet position when reaching preset upper limit of gas cabinet 1, also can avoid the generation of the phenomenon of not reporting to the police caused of being failure to actuate because of single position limit switch to a great extent, and then improve the reliability and security that described in the application, warning device uses.
In addition, piston 5 not yet on move to the upper limit position preset time, the warning that all can not cause alarm 8 is led in the misconnection of any position limit switch in above-mentioned three position limit switches, this avoids the false alarm phenomenon because single position limit switch misoperation causes to a certain extent, further increases the reliability and security that warning device described in the application uses.
Above mode of execution only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to aforementioned embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in aforementioned each mode of execution, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each mode of execution technological scheme of the utility model.
