Abstract

The utility model relates to a water level self-controlling device, comprising an upper transverse rod (3) part, a float rod (8) part, and a lower transverse rod (10) part. The upper transverse rod (3) and the lower transverse rod (10) are connected into integration through a spring (1), a support frame (2) and the float rod (8). The utility model has the advantages of labor saving, no manual operation, simple structure, low cost, and convenient operation, which can be used for the self control of water pumping in factories of a town or broad countryside.

Description

Water level self-controlling device

The utility model is to belong to a kind of device that the control water tower level is used.

The device that the control water tower level is used in the city is all a lot of at present, as water tower level automatic controller, liquid surface lifting self-actuated controller etc., its cost is all expensive, can't be used widely in cities and towns, particularly a lot of at the rural area water tower, and water pump draw water can not automatic control, Push And Release artificially, therefore this phenomenon of wanting water not have electricity often occurs, and also do not purchase this more expensive automatic controller, so this can not be adopted by vast rural area.

The purpose of this utility model is to provide a kind of simple in structure, cheap for overcoming above-mentioned shortcoming, can be adapted to the water level autocontrol device that cities and towns and wide rural area are used.

Technical solution of the present utility model is: according to the equilibrium condition of lever and the condition of drifting along of object, if the object that is immersed in the liquid is subjected to the gravity that buoyancy is subjected to greater than it, object is come-up just; If buoyancy is less than gravity, object just sinks; If buoyancy equals gravity, object just can rest on the place of any degree of depth in the liquid.And the elongation and the pulling force of utilization spring, the purpose that is used for reaching the water tower level automatic control of magnet.Be that liquid level drops to the end and starts working during liquid level, liquid level quits work when rising to the highest liquid level.

This accompanying drawing has been described an embodiment of the present utility model.

1---spring 2---support 3---cross tube

4---upper conductor contact 5---lead 6---chutes

7---ball 8---fly rod 9---iron plates

10---sheer pole 11---permanent magnetism sheet 12---slotted eyes

13---buoy 14---lower conductor contact

Below in conjunction with accompanying drawing the utility model is described in detail.The water level autocontrol device that is proposed is made up of parts such as cross tube (3), fly rod (8), sheer pole (10) three parts, and cross tube (3) is to be linked to be an integral body by spring (1), support (2) and fly rod (8) with sheer pole (10).And cross tube (3) is movable the hinge with support (2) top, and support (2) lower end is fixed on the sheer pole (10), and sheer pole (10) is again directly to fall within on water tower.

Be equipped with two upper conductor contacts (4) in the middle of the cross tube described in the utility model (3), be connected with lead (5) between two contacts, the right-hand member design has a chute (6), is equipped with ball bearing (7) in the chute (6), and right top is equipped with an iron plate (9) again.

The corresponding two lower conductor contacts (14) that are equipped with cross tube (3) in the middle of the sheer pole described in the utility model (10), two contacts are connected with lead respectively, right-hand member design has a slotted eye (14), the right-hand member of slotted eye (12) again with the corresponding permanent magnetism sheet (11) that is equipped with of iron plate (9) on the cross tube (3).

Fly rod described in the utility model (8) is the more piece metal round rod that can arbitrarily freely stretch for, pass the slotted eye (12) on the sheer pole (14) and be fixed on the ball bearing (7) in cross tube (3), the chute (6), so that fly rod (8) can swing, be equipped with a buoy (13) in the top down at its fly rod (8) again in chute (6).

Spring described in the utility model (1) is the left end of design and installation between upper and lower cross bar (3) (10).

Course of work principle of the present utility model: this device must meet, and the pulling force of its spring adds that gravity that the gravity of resistance arm equals fly rod adds all the part gravity on power arm and the power arm, equals the gravitation of magnet to iron plate at the gravity of its buoy.

When the water surface descended, the buoy that swims on the water surface also descended with the decline of water level, and buoy floats on the surface all the time, when decline of water table to following system point level the time because the buoy and the water surface join, be vacuum, on but be subjected to atmospheric effect, make the cross tube out of trim, power arm one end overweights resistance arm one end, the spring elongation, cross tube descends, and two conductor contacts were connected mutually about decline made always, and iron plate attracts mutually with the permanent magnetism sheet, this moment, circuit was connected, and water pump is started working.When otherwise water level rises, following system point is immersed in the water, this moment, buoy was bubbled through the water column again, and rise with the rise of water level, and at this moment power arm still is subjected to magneticaction, when the floating supreme system point of buoy, water pump does not still quit work, therefore buoy immerses in the water gradually, and the buoyancy that power arm one end is subjected to increases gradually, and gravitation remains unchanged, when buoyancy during greater than gravitation, make iron plate and permanent magnetism sheet, and two pairs of contacts disconnect the spring reinstatement simultaneously, cross tube rises rapidly, power supply blocks, and water pump quits work, and reaches the purpose of automatic control.

The utlity model has following advantage: 1. it can save manpower, need not people's operation, and manpower is used for the work of other side; 2. can save a large amount of time, want water not have the phenomenon of electricity and overcome this often appearance; 3. simple in structure, cheap, can be adapted to the automatic control of drawing water of cities and towns unit and wide rural area and use.
