Abstract
The utility model discloses a water level alarm which comprises a first water level detection block and a second water level detection block, and also comprises an alarm circuit, wherein the alarm circuit comprises an armature, two movable contacts and two static contacts, the two movable contacts are simultaneously fixed on one end of the armature, and the other end of the armature is connected with a spring; a warning indictor and a power supply A are serially connected between to the static contacts; an electromagnet is arranged below the armature, one end of a wire of the electromagnet is serially connected with the first water level detection, and the other end of the wire of the electromagnet is serially connected with a power supply B and the second water level detection. The warming indictor is a warning light or a buzzer, and the power supply A and the power supply B are alkaline batteries or lithium batteries. The water level alarm has the advantages of simple structure, easy realization, timely alarming, economy and practicability, and is suitable for popularization and application in general small farmers.
Description
Technical field
The utility model relates to a kind of warning device, relates in particular to a kind of level alarm for water.
Background technology
In the proportion of crop planting process, requisitely to relate to operations such as arable land, sowing, fertilising, irrigation, and each link plays vital effect for the results of crops, usually, irrigate and mostly adopt water pumper or water channel irrigation method, by the artificial mark of monitoring at any time water level, basically can effectively control the water level of irrigation.Certainly, the higher Automated water level alarm of sensitivity is arranged also in the prior art, its complicated structure, cost is high, is difficult for popularizing in general small-sized peasant household.
The utility model content
For above-mentioned prior art, the utility model provides a kind of water level alarm, and it is simple in structure, is easy to realize, and is with low cost, is highly suitable for to popularize in the general small-sized peasant household to use, and has and reports to the police in time economical and practical advantage.
In order to solve the problems of the technologies described above, the technical scheme that a kind of water level alarm of the utility model is achieved is: comprise the first water-level detecting piece and the second water-level detecting piece, also comprise a warning circuit, described warning circuit comprises an armature, two moving contacts and two stationary contacts, two moving contacts are fixed on an end of armature simultaneously, and the other end of described armature is connected with a spring; Be in series with attention device and power supply A between two stationary contacts; The below of described armature is provided with an electromagnet, and wire one end of described electromagnet is connected in series with the first water-level detecting piece, and the other end of the wire of described electromagnet is connected in series with the second water-level detecting piece with a power supply B.
A kind of water level alarm of the utility model, wherein, described attention device is warning lamp or hummer, described power supply A and power supply B are alkaline battery or lithium battery.
Compared with prior art, the beneficial effects of the utility model are:
Circuit in the utility model water level alarm is very simple, only need several low-cost electronic devices and components just can realize the warning function of water level, be particluarly suitable for popularizing in the general small-sized peasant household and use, not only reduced the unnecessary worry of peasant household in the process of irrigating the fields, and can grasp at any time water level, thereby save the electricity charge and water rate, avoid the wasting of resources, play a multiplier effect.
Description of drawings
Accompanying drawing is the structural representation of a kind of water level alarm of the utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
As shown in drawings, a kind of water level alarm of the utility model, comprise the first water-level detecting piece 2 and the second water-level detecting piece 9, it is characterized in that, also comprise a warning circuit, described warning circuit comprises that an armature 5, two moving contacts 6 and 7, two moving contacts 6 of two stationary contacts are fixed on an end of armature 5 simultaneously, and the other end of described armature 5 is connected with a spring 3; Be in series with attention device 8 and power supply A between two stationary contacts 7, described attention device 8 is warning lamp or hummer; The below of described armature 5 is provided with an electromagnet 4, and wire one end of described electromagnet 4 is connected in series with the first water-level detecting piece 2, and the other end of the wire of described electromagnet 4 is connected in series with the second water-level detecting piece 11 with a power supply B.Power supply A and power supply B in the utility model water level alarm all can adopt alkaline battery or lithium battery.
The utility model water level alarm in use, if water level 1 is lower than the first water-level detecting piece 2, no current passes through in the electromagnet 4, at this moment, separated attitude between two moving contacts 6 and two stationary contacts 7 does not work as the warning lamp of attention device 8; When water level 1 arrives the first water-level detecting piece 2, electromagnet 4 produces magnetic field, under magnetic fields, the armature 5 that is positioned at electromagnet 4 tops is inhaled lower, so that be positioned at two moving contacts 6 of armature 5 homonymies and two stationary contacts, the 7 respectively adhesives of its below, the circuit turn-on of warning lamp 8 is realized water-level alarm when warning lamp is bright.Simultaneously, if adopt hummer as attention device, then the hummer buzzing is as water-level alarm.
Although the above is described the utility model in conjunction with figure; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
