Description

Water level automatic controlled submersible pump

Technical field

The invention belongs to a kind of electrical category product, a kind of water level automatic controlled submersible pump.

Background technology

When existing immersible pump works in the environment of the narrow and small humidities such as engineering water-level sedimentation well, it is desirable to have people nurses.Ward's water pump to be opened when the water level that seeps water rises to certain altitude, ward will switch off the pump when water level decreasing to certain altitude or when being drained.As during unmanned nurse with regard to uncontrollable infiltration water level, do not have the purpose of lowering of watertable.When water is drained as closed immersible pump without ward, immersible pump operates under long-time anhydrous condition, and temperature will raise and burn out motor for submerged pump.

And there is presently no way by the main cause that immersible pump and water level controller are combined is the problem of water-level probe.Current water-level probe is made up of metal probe and insulated conductor, water-level probe is connected by insulated conductor with water level controller, three water-level probes are placed in parallel in pond, can not touch between three probes, being carried out detecting water level height by water-level probe, controller controls water pump and realizes what water level automatically controlled.It is widely used in the water lev el control of upper pool and sink.

The present invention is specific to immersible pump in the environment of the narrow and small humidities such as engineering water-level sedimentation well and can automatically control infiltration water level and design, the water lev el control in subordinate pond.Its principle is: water level controller is given upper, the signal of telecommunication of lower water-level probe certain voltage, grounded probe is placed on the position close to basin bottom, upper water-level probe is placed on the peak level position that you require to control, lower water-level probe is placed on the lowest water level position that you require to control, utilize the electric conductivity of water, when water level arrives the position of the peak level requiring control, the water-level probe of peak connects conduction with the grounded probe of basin bottom, water level controller action, start pumping drainage, time below water level decreasing to lowest water level probe, the probe of lowest water level disconnects with the grounded probe conduction of basin bottom, water level controller action switches off the pump, the purpose back and forth automatically controlled with realization with this.But current water level controller also could not the control of immersible pump in the environment of the automatic control engineering water level sedimentation narrow and small humidity such as well, its reason is: there will be three problems in the environment of such narrow and small humidity, the borehole wall that one is extreme higher position, the probe of extreme lower position is easy with moist is touched and is connected conduction with popping one's head in by ground of well bottom, and causes controller misoperation.Two is that probe does not has expelling water ability with wire, and when mutually touching or being wound around occur in probe and wire, extreme higher position, extreme lower position probe are turned on by the water of conductive line surfaces, make water level controller distinguish upper and lower water-level probe and cause controller misoperation.Three is in coastal area, owing to the salinity of subsoil water is higher, probe and wire are immersed in the water of high salinity for a long time, probe and conductive line surfaces are understood salinization and are formed conductive layer, probe connects conduction with the salinization layer on insulated conductor surface, as long as probe and wire, wire and wire touching occur or be wound around, extreme higher position, extreme lower position probe are turned on by the salinization layer of conductive line surfaces and the grounded probe of well bottom, and cause controller misoperation.

Summary of the invention

The invention aims to realize the purpose of unmanned nurse when immersible pump works in the environment of the narrow and small humidities such as engineering water-level sedimentation well.The implementation of the present invention: install an insulation expelling water cover on existing probe additional and isolate probe and wire or the touching of the borehole wall, probe length is as the criterion with parallel with edge expelling water cover port face plane, it is ensured that when insulation expelling water cover actinal surface touches water, probe also can touch water.Insulation expelling water cover and sealing plastics sieve tooth connect (I am by named for this water-level probe expelling water water-level probe).When the expelling water water-level probe that insulate is vertically arranged in water under the effect of external force, certain air pocket can be formed in insulation expelling water cover.So can stop probe and moist wire or borehole wall touching and the grounded probe conducting of extreme higher position, extreme lower position probe and well bottom occurs, and cause water level controller misoperation.And in the higher area of subsoil water salinity, in order to prevent insulating expelling water cover by salinization, can be by upper according to oneself control of three expelling water water-level probes, the needs of lower water level, insert in same metal tube or be attached on a metal bar, action of gravity is utilized vertically to insert in water, the one section of air pocket that so will produce in insulation expelling water cover, make water can not with insulation the whole contact internal walls of expelling water cover, guarantee to insulate the internal part of expelling water cover not by salinization, to ensure there is one section of insulated part inside insulation expelling water cover, probe and conductive line surfaces is stoped to be conducted electricity because of salinization, guarantee that water level control device will not misoperation.

Water level controller is inserted in the case of immersible pump top, immersible pump distal hood is fixed a metal tube rod, ground connection expelling water water-level probe is installed in the extreme lower position of metal tube rod, upper and lower water-level probe is needed to be installed in detecting water level on metal tube according to controlling water level, with realize immersible pump can the purpose of automatic control water level in the environment of the narrow and small humidities such as engineering water-level sedimentation well.

The present invention is compared with prior art, settle at engineering water-level because achieving immersible pump in the environment of the narrow and small humidities such as well, in the case of unmanned nurse, achieve the purpose automatically controlling infiltration water level, reduce groundwater level, save artificial, improve the benefit of enterprise.
