Abstract
The utility model provides a water level alarm knife for a water tower in the water supply field of the water tower, which is mainly characterized in that a water level alarm device is arranged on a knife seat of a knife switch used for a water pump of the water tower; the water level alarm device adopts a single-closed alarm; a contact is arranged at the upper part of the knife switch corresponding to a handle after switching on; and a circuit loop is provided with a contact terminal corresponding to the set water level of the water tower. In the utility model, the existing knife switch and the alarm are improved, after switching on, the water pump is started for water supply, the knife handle is associated with the alarm; when the set water level is reached, the contact terminal automatically switches on an alarm circuit for alarming; when the knife is switched off, the water pump stops water supply, the alarm circuit is switched off, and the alarming is automatically released. The utility model has the advantages of quantitative water supply, overflowing and freezing prevention, water and electricity saving, safety and convenience and long service life.
Description
Technical field
The utility model belongs to the water supply field, relates to a kind of knife switch, is specifically related to a kind of water tower level warning plug-in strip.
Background technology
In recent years, rural, cities and towns institutional settings or peasant family generally use installs small-sized water tower (or water supply tank, feed cistern) on the roof, adopt water pump that well water is risen storage and go in the water tower.But, in water supply process, water tower spilling water phenomenon often takes place, not only waste water source, electric power, also influence environmental sanitation.
For addressing this problem, the someone works out the anti-overflow product.As float switch, the control point is prone to fault or electric leakage danger in water tower.
Summary of the invention
The inventor finds that family expenses water tower hydrotechny exists certain defective in practical experience of life for many years, through exploring repeatedly, purpose is to propose a kind of water tower level warning plug-in strip, can solve a water tower spilling water and an electric leakage difficult problem preferably.
For realizing purpose, the technical scheme that the utility model is taked is a kind of water tower level warning plug-in strip of design, its structure comprises: knife switch, the water-level alarm device is set on blade base, the water-level alarm device is arranged on the contact of single closed alarm and the corresponding knife switch of the back handle that closes a floodgate top, is provided with and the corresponding contact of water tower designated water level on the single loop circuit.
The utility model is taked abovementioned technology, existing water tower water-feeding pump is improved with knife switch and unidirectional closed alarm, designed this water tower level warning plug-in strip, after knife switch closed a floodgate, starting mode of pump supplied water in water tower, this moment, male contact handle was associated with single closed alarm contact, after water level reached designated water level in the water tower, the contact that is arranged in the water tower was connected alarm circuit automatically, and alarm promptly can send the warning sound; When pulling down plug-in strip, water pump then stops to supply water in water tower, reports to the police promptly to automatically terminate.Have quantitative water supply, anti-overflow is antifreeze, water-saving and electricity-saving, and safe ready, advantages such as long service life are for the user provides a kind of desirable water tower water-feeding control product.
Description of drawings
Fig. 1 represents the structural representation of the utility model water tower level warning plug-in strip.
Embodiment
In conjunction with the accompanying drawings and embodiments, further specify the concrete structure of the utility model water tower level warning plug-in strip.
The embodiment of the utility model water tower level warning plug-in strip, referring to Fig. 1, its structure comprises: water tower water pump knife switch 1, male contact handle 1.1, single closed alarm 2, single closing contact 2.1, contact 2.2.Wherein single closed alarm 2 is installed in blade base one side of knife switch 1, single closing contact 2.1 is arranged on the top of knife switch 1, with be associated after handle 1.1 closes a floodgate, on the circuit loop of single closed alarm 2, contact 2.2 is set, contact 2.2 can be probe or bare wire, and is corresponding with the water tower designated water level.
Under the normal operating position, contact 2.2 is set on the higher position, improves the water level in the water tower; Under winter cold low temperature condition, contact 2.2 is set in lower position, reduce the water level in the water tower, satisfy one day water consumption, prevent that water tower from freezing night, realization can waterproof be overflow and can waterproof be frozen again.Because the power supply of alarm adopts dc-battery, separates with pump power, leaky can not take place in water tower.
This water tower level warning plug-in strip of the present utility model is applicable to two-phase, Three-phase knife switch.
