Abstract

The utility model discloses a submerged hydraulic pressure induction switch belonging to an automatic water level controller. The submerged hydraulic pressure induction switch uses a principle that the pressure at the bottom of a water tower or a pool changes following the depth of the liquid level, and the submerged hydraulic pressure induction switch is provided with a hydraulic pressure induction board to receive the changing pressure and uses the pressure to control the switching of a motor to automatically control the water level. The submerged hydraulic pressure induction switch can adjust an adjusting screw to be adapted for water towers or pools with different water depths. The submerged hydraulic pressure induction switch has the advantages of high reliability and easy installation, so the submerged hydraulic pressure induction switch is an ideal water level auto-control switch for the water tower.

Description

Submerged hydraulic pressure induction switch

The utility model belongs to a kind of water level automatic control switch.

At present, the water level automatic control device that uses in the society, the application number that the nearest Patent Office of the People's Republic of China of the self-con-tained unit utility model patent communique of most employing float-types is announced is 87204160 water tower level automatic controller, be to utilize a water level switch that the water conducting is being arranged, the installation of the float-type control device that the principle of anhydrous outage is made is cumbersome, and needs the professional to install; The water tower level automatic controller needs that a water level switch respectively is installed up and down and just can achieve the goal, and cost is than higher.

The purpose of this utility model provides a kind of submersible type hydraulic coupling inductive switch, makes it the low installation of cost easily, and is easy to use, reliable in action.

Technical solution of the present utility model is the principle that the pressure that utilizes water tower or basin bottom changes along with the variation of liquid level height, design the pressure that a hydraulic coupling tablet acceptance is changing, utilize this power to realize controlling the energising or the outage of motor, to reach the water level purpose of control automatically.

Accompanying drawing has been described an embodiment of the present utility model, is described in detail below in conjunction with accompanying drawing.As shown in Figure 1, this switch is gone up by pressure sensing cap (12) and is connected switch housing (4) formation switch housing, designing from top to bottom in it has power transmission handle (13), spring (15), spring (11), contact chip (16), nut (10), contact chip (8), spring (19), adjusting screw(rod) (6), forms the transmission mechanism of power by them.Design a cover binding post system again, by wiring column base (17), be embedded in wherein binding post (18), (9) and (7), adorn a spacing fixed head (5) formation above.A small sircle hole is respectively opened on three binding post tops, so that pass the wiring hold-down screw.For the sake of security, insert an ion conducting protective tube (3) in the upper space position, after the switch housing breakage, water enters the switch the inside, cause hydraulic coupling tablet internal and external pressure balance, do not play induction pressure, thereby to motor effect out of hand, motor turns round continuously.Ion conducting protective tube has just in time solved this problem.Because the conducting salt in the ionic tube enter torrent wet after, promptly conduction increases the electric current on the magnetic starter electromagnetism circuit, blowout makes the magnetic starter tripping operation, reaches the purpose that stops motor rotation.Press the circuit of Fig. 9 principle schematic is installed, draw 4 leads in switch, the place in circuit system puts into the bottom to switch, can devote oneself to work.Its course of work is: put into the bottom of water when switch, the base pressure of water is low, under the effect of spring (15) and (19), contact chip (8) is contact binding post (18) and (9) earlier, when contact chip (16) contact binding post (18), electric motor starting, work is drawn water.Along with improving constantly of water level, the pressure of bottom continues to increase, when the hydraulic coupling of bearing when the hydraulic coupling tablet of pressure sensing cap surpasses the elastic force of spring (15), spring (15) is compressed, power transmission handle (13) is along with up pushing away, contact chip (16) breaks away from binding post (18), continue to increase hydraulic coupling, power transmission handle (13) continues up top, up to the nut (10) of power transmission button adjusting screw(rod) (6) up push up, is screwed in contact chip (8) the disengaging binding post (9) and (18) on the adjusting screw(rod), the magnetic starter tripping operation, the motor outage shuts down, and pump does not draw water.When water tower (or pond) decline of water table to the regulation the position time, under the effect of spring (19) and (15), contact chip (8) contacts with binding post respectively with (16), the connection circuit, starter motor work.So constantly circulate, reach the purpose of automatic control water level.Pressure sensing cap (12) is designed to similar cook's hat, and crown is the hydraulic coupling tablet, and intermediate flange partly is made into the sheet metal of plastics or rubber or flexible, is convenient to compressing and stretching.At place, protruding top, embedding steel wire diameter in lining is 2 millimeters a wire loop, and to guarantee the shape of flange, top connector machining internal thread is so that link to each other with loam cake (4).It is the circle handle that power transmission handle (13) is designed to following, and the higher authorities' rod end embeds the threaded Metallic rod of car, so that the nut of screwing on (10); Contact chip (8) and (16) respectively stamp out 2 boss points, and it is reliable to be beneficial to contact; In the middle of the contact chip (8) is screwed hole, wears adjusting screw(rod).In order to improve the sensitivity of spring (15), diameter of coiled is big during making, the Spring capable of diameter varying that diameter is little.Binding post (18), (9), (7) and spacing fixed head (5) are designed to the structure as Fig. 5, Fig. 6, Fig. 7 and Fig. 4.Ion conducting protective tube (3) is designed to structure shown in Figure 8, and profile can be designed to cylindrical or pane shape, and two ends are drawn positive and negative electrode respectively with metal skin packet header (21) sealing from two.The centre is designed to have the insulation duroplasts cylinder of two circular holes, as the shell (22) of ionic tube, is used for connecting and fixedly positive and negative polarities and wire netting (23) the inside dress ionic agent (24).Design has uncovered cylinder (25) in the middle of wire netting and the plastic cylinder.Ionic agent can be with the salt of various conductions, and the ion guide siphunculus is non-conductive when dry, the moist back of water inlet conduction.Four wires (1) of drawing from switch seal with plastic bushing (2), and must there be the gap of blowing air the centre, will note guaranteeing the sealing of the junction of plastic bushing and switch housing (4) especially.This switch is by the adjustment of adjusting screw(rod) (6), and use in the water tower or the pond that can adapt to the different depth of waters.

The utility model is on probation through model machine, and reliable in action is easy to use, install easily, and be a kind of comparatively ideal water tower level autocontrol switch.
