Abstract

The utility model relates to an automatic controller for the water level of a water tower and a motor. The utility model comprises a housing, a conducting wire, a water filling ball, a float, and a transmission rod, wherein, the conducting wire is connected with the motor, and the water filling ball is arranged in a water body. The utility model is characterized in that the transmission rod is connected with one end of an automatic control pipe; the bottom surface of the center part of the automatic control pipe is provided with a circuit switch which is provided with a fixing contact terminal and a movable contact terminal; the automatic control pipe lifts or drops with the lift of the water level or the drop of the water level, the circuit switch is cut off or is switched on, and the motor and a water pump are controlled to work. The utility model which has the advantages of simple structure, little failure, convenient use, low cost, and wide applicability is suitable for liquid level control for the water tower, a water tank, and an underground water well.

Description

Water tower level and motor self-actuated controller

The utility model relates to a kind of water tower level and motor self-con-tained unit.

The motor injection water tower that draws water water often occurs and completely forgets the phenomenon of operating a switch, and causes when water is long in the tower excessive.Take out when using well water, sometimes even drain water and do not shut down, cause motor to burn out, economy is suffered a loss.For this reason, develop a kind of water level and the motor self-con-tained unit is very necessary.Consult Chinese patent literature, 6 of relevant patents were arranged so far in 1985, the water level autocontrol device of yiyang, hunan application, (number of patent application: 87204160) electric elements such as water level switch, transformer, transistor, capacitor are arranged in the structure; The automatic level controller (90216842) of Great Wall, Ruian, Zhejiang mechanical fitting factory application is provided with parts such as air intake opening, air storage chamber, convoluted diaphragm, turriform spring; The patent (92206890) of the yellow refined full application in Zhejiang is provided with delay circuit, sound light alarming circuit, failure detector circuit, fluid level controller or the like; Other patents have electric pole type water level control etc.Make a general survey of above-mentioned patent documentation, method for controlling water level is various, but most of patent all abandons in advance, is not applied.One of reason, structure are complicated, and cost is higher, easy break-down, and applicability is low.

The purpose of this utility model provide a kind of simple in structure, can control water tower (case) water level automatically, and by water level control motor rotation and the device of closing down.

The technical solution of the utility model is: water tower (case) water level and motor automatic controller, comprise the lead that connects motor, be positioned at the water filling ball of water body, the float that links to each other with the water filling ball, connect drive link on the float, drive link with link to each other from keyholed back plate, from bottom surface, keyholed back plate middle part one contactor is arranged, be provided with moving contact and decide contact, decide contact and link to each other with binding post, lead.Decline of water table, float drive from keyholed back plate contact are connected, the motor and water pump running; Water level rises to certain altitude, and moving contact separates, and motor shuts down and do not draw water.

The utility model has following advantage than prior art:

1, simple in structure, fault is few, easy-maintaining.

2, cost is low, and is easy to use, and applicability is wide, not only can be used for water tower (case) water filling control, when also can be used for well and drawing water, and underground water table control.

Fig. 1 is the utility model structural representation.

Find out that from figure shell 10 is fixed in support 11 bottoms, have one in the shell from keyholed back plate 9, there is a contactor its bottom surface, pipe middle part, and switch is provided with binding post 7, and the binding post upper conductor links to each other with motor.Set contact on the binding post, decide that there is moving contact 8 corresponding position on the contact.One rotatable iron ball 6 is arranged in keyholed back plate, and the pipe bottom has a backguy 5 to link to each other with drive link 4, is connected with a float 3 below the drive link, has a water filling ball 1 continuous by backguy 2 under the float.Float 3 is arranged in water tower (case).When water level reduced, water filling ball, float and drive link drove from the keyholed back plate right-hand member and descend, and iron ball descends, and made contactor decide contact and connected, and motor rotation draws water.Increase with the water yield, float 3 rises, and drive link promotes to rise from keyholed back plate 9 right-hand members, and iron ball progressively is rolled into left end in the pipe, and switch disconnects motor and quits work.As the right lead is connected on the binding post of the left side, its effect is then opposite, and float rising circuit is connected, machine operation, and this mode of connection can be used for when well draws water, underground water table control, the length that only needs to regulate drive link 4 and backguy 2 just can.Wide speech, be applicable to source liquid level control.

Be pointed out that: in the practical application, should select corresponding A.C. contactor for use according to the power of pump motor, single-phase pump is different with two-phase pump mode of connection.Source liquid level control is different with purpose liquid level control wiring.In the production, shell, all adopt plastic production from keyholed back plate, drive link, float, water filling ball.
