Abstract

The utility model relates to a mechanical type water level controller. The utility model is characterized in that a moving rod moving from top to bottom following a floating ball is penetrated through a sleeve barrel which is fixed on a supporting base rack and is limited by the sleeve barrel, a travel colliding rod on the moving rod is limited by an opening groove on the supporting base rack, and the supporting base rack is respectively fixed with an upper travel switch and a lower travel switch which are corresponding to contacts of the travel colliding rod and can cut and switch a power supply of a water pump at the time of the contacts of the travel colliding rod colliding and having contact with the upper travel switch and the lower travel switch on the upper end and the lower end of the opening groove. The utility model can control the upper travel switch and the lower travel switch for working by the buoyancy and gravity of the floating ball, and the utility model has the advantages of simple structure and reliable operation.

Description

The mechanical type water level controller

The utility model relates to a kind of water level controller.

Being used for water tower, water tank and cistern etc. at present needs the water level controller of the container of liquid level control, most complex structure, though the water level controller structure that has is comparatively simple, but its easy break-down in service, a kind of water level controller is for example arranged, its design feature is that it is made up of housing, contact switch and support, and its reliability is just relatively poor.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and mechanical type water level controller a kind of simple in structure, reliable is provided.

The purpose of this utility model realizes by following technical proposals:

The mechanical type water level controller has a mounting, ball float, the motion bar that moves up and down with ball float, its technical scheme is that described motion bar passes the sleeve that is fixed on the mounting and spacing by this sleeve, spacing with the stroke collision bar that motion bar connects as one by the open slot on the mounting, the contact position that is fixed with its position and stroke collision bar on end bearing frame on the open slot is corresponding, cut off the upper stroke switch of the pump power that draws water when the contact of stroke collision bar contacts with its collision, the contact position that is fixed with its position and stroke collision bar under open slot on the end bearing frame is corresponding, when contacting with its collision, the contact of stroke collision bar connects the lower stroke switch of the pump power that draws water.

The utility model is spacing by this sleeve because described motion bar passes the sleeve that is fixed on the mounting, spacing with the stroke collision bar that motion bar connects as one by the open slot on the mounting, the contact position that is fixed with its position and stroke collision bar on end bearing frame on the open slot is corresponding, cut off the upper stroke switch of the pump power that draws water when the contact of stroke collision bar contacts with its collision, the contact position that is fixed with its position and stroke collision bar under open slot on the end bearing frame is corresponding, when contacting with its collision, the contact of stroke collision bar connects the lower stroke switch of the pump power that draws water.Like this, it relies on its ball float buoyancy and gravity to realize the control of travel switch and carries out work, when the container water level at its place rises, ball float drives motion bar along upwards slip (motion) of sleeve under buoyancy, rise to when requiring water level, upper stroke switch is touched in the contact of stroke collision bar, cut-out draw water water pump power supply and stop to go up water, when the container decline of water table at its place, ball float under action of gravity, drive motion bar along sleeve to lower slider (motion), when reducing to lowest water level, lower stroke switch is touched in the contact of stroke collision bar, connection draw water water pump power supply and begin to go up water, container carries out water storage.It is simple in structure, and is reliable, need not manually-operated, finishes the control to liquid level automatically, and its liquid level range of control can reach 0.1-100 rice, can be widely used in the container that water tower, water tank and cistern etc. need liquid level control.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is two-part structural representation for the utility model is decomposed into.

As shown in Figure 1 and Figure 2, the utlity model has mounting 4, ball float 1, the motion bar 2 that moves up and down with ball float, sleeve 3, travel switch 7 and 5, stroke collision bar 6 up and down.Prop up mounting 4 its branch base 41 and stand 42 two parts, the base of a mounting is in order to fix with the container at its place, and the stand of a mounting has open slot 43.Motion bar 2 and the ball float 1 that moves up and down with ball float is to pass the two center pit by the elongate rod that its two ends have a spacing head to be connected as a single entity, one of them is the termination of elongate rod for described two spacing heads, another nut (an elongate rod wherein end has a bit of screw thread) for being threaded with elongate rod.Described motion bar 2 passes the sleeve 3 that is fixed on the mounting and spacing by this sleeve, and motion bar moves up and down along this sleeve.Spacing with the stroke collision bar 6 that motion bar connects as one by the open slot 43 on the mounting, be fixed with the upper stroke switch 7 that its position is corresponding with the contact position of stroke collision bar 6, cut off the pump power that draws water when the contact 61 of stroke collision bar contacts with its collision on the end bearing frame on the open slot 43, be fixed with the lower stroke switch 5 that its position is corresponding with the contact position of stroke collision bar 6, connect the pump power that draws water when the contact 61 of stroke collision bar contacts with its collision on 43 times end bearing framves of open slot.Label 44 is upper and lower stroke switch 7 and 5 mounting holes among Fig. 2.
