Abstract
The utility model relates to a condensing tower liquid-level notification device, comprising an electrode, a liquid level notification device on the electrode and composed of a liquid level notification circuit. A simple circuit structure is used for determining whether water shortage is present in the condensing tower or not, if water shortage is present in the condensing tower, a loudspeaker automatically alarms and remedial measure is timely used. The condensing tower liquid-level notification device is convenient and practical.
Description
Technical field
The utility model relates to a kind of condensing tower liquid level informing device.
Background technology
Condensing tower is the container of a sealing often, is difficult to observe with the naked eye liquid level wherein generally speaking, in case lack of water occurs, will reduce condensation effect greatly, even damages relevant equipment, therefore, keeps in the condensing tower certain liquid level very important.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, automatic condensing tower liquid level informing device of reporting to the police of lack of water.
For achieving the above object, the technical solution adopted in the utility model is: a kind of condensing tower liquid level informing device, comprise electrode one, electrode two, and be connected with the liquid level informing device on the described electrode; Described liquid level informing device informs that by liquid level circuit constitutes, and its circuit structure is as follows:
Liquid level informs that circuit is by resistance R, capacitor C 1, C2, adjustable resistance RP, time-base integrated circuit IC, loudspeaker BL, switch S, the 6V direct supply is formed, wherein: the 8. and 4. pin of the end of adjustable resistance RP and variable termination time-base integrated circuit IC, the other end of adjustable resistance RP is through resistance R, capacitor C 1 receiving electrode one, the 7. pin of time-base integrated circuit IC connects between adjustable resistance RP and the resistance R, time-base integrated circuit IC 2., 6. between pin connecting resistance R and the capacitor C 1, time-base integrated circuit IC 2., 6. the pin receiving electrode two, the 1. pin of time-base integrated circuit IC connects the negative pole and the electrode one of 6V direct supply, and ground connection, the 3. foot meridian capacitor C2 of time-base integrated circuit IC, loudspeaker BL connects 8. and the 4. pin of time-base integrated circuit IC, and the positive pole of 6V direct supply connects 8. and the 4. pin of time-base integrated circuit IC through switch S.
Because technique scheme, the beneficial effects of the utility model are: utilize simple circuit configuration whether promptly to know in the condensing tower lack of water, if lack of water just loudspeaker is reported to the police automatically, in time adopts remedial measures.Convenient and practical.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following instructions, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Description of drawings
Accompanying drawing is circuit theory diagrams of the present utility model
Mark among the figure: 1-electrode one 2-liquid level is informed circuit 3-electrode two
Embodiment
As shown in drawings, a kind of condensing tower liquid level informing device comprises electrode 1, electrode 23, is connected with the liquid level informing device on the described electrode; Described liquid level informing device informs that by liquid level circuit 2 constitutes, and its circuit structure is as follows:
Liquid level informs that circuit 2 is by resistance R, capacitor C 1, C2, adjustable resistance RP, time-base integrated circuit IC, loudspeaker BL, switch S, the 6V direct supply is formed, wherein: the 8. and 4. pin of the end of adjustable resistance RP and variable termination time-base integrated circuit IC, the other end of adjustable resistance RP is through resistance R, capacitor C 1 receiving electrode 1, the 7. pin of time-base integrated circuit IC connects between adjustable resistance RP and the resistance R, time-base integrated circuit IC 2., 6. between pin connecting resistance R and the capacitor C 1, time-base integrated circuit IC 2., 6. the pin receiving electrode 23, the 1. pin of time-base integrated circuit IC connects negative pole and the electrode 1 and the ground connection of 6V direct supply, the 3. foot meridian capacitor C2 of time-base integrated circuit IC, loudspeaker BL connects 8. and the 4. pin of time-base integrated circuit IC, and the positive pole of 6V direct supply connects 8. and the 4. pin of time-base integrated circuit IC through switch S.
Principle of work: electrode 1, electrode 23 are immersed in the water that is in normal liquid level, are equivalent to each other be communicated with, and capacitor C 1 can not be charged by short circuit, so the circuit failure of oscillation, and loudspeaker BL is sounding not.In case when abnormal conditions occurring and being lack of water, electrode 1, electrode 23 just no longer contact with water and are open-circuit condition, electric C1 charging, circuit starting oscillation, loudspeaker BL sounding and inform operating personnel.Regulate the value of adjustable resistance RP, can change the sound frequency of loudspeaker BL.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
