Abstract

The utility model discloses an automatic water supply device for obtaining water from underground. A water pump is connected to an original well pipe. A well pipe of the upper part of the water pump is provided with a stop valve. The water pump is connected into a water storage device by a water pipe and the stop valve. The water storage device is a sealed container. The upper part of the sealed container is provided with a pressure sensing device. The press sensing device is connected with a pressure relay. The connection point of the pressure relay is connected into an automatic controller. A motor of the water pump is also connected into the automatic controller. A waster outlet pipe is led out at the lower part of the water storage device. The utility model has the advantages of time saving, labour saving, convenient use, small volume for total composition, simple structure for an automatic control part, low cost and convenient installation. The water storage device can be arranged under the freezing prevention layer of ground to save space.

Description

Single-phase underground water lift Automatic Water System

The utility model relates to a kind of and the supporting underground water lift Automatic Water System of family expenses hand well.

Mostly the well that present rural area is used is hand, wastes time and energy; The usefulness three-phase alternating current electric control water lift that has, its electrical structure is complicated, the cost height.

The purpose of this utility model is to provide a kind of single-phase underground water lift Automatic Water System, makes the hand well become tap water, and time saving and energy saving, easy to use, cost is lower.

The technical solution of the utility model is as follows:

This device is to connect water pump on former and pipe, the well casing on water pump top has a non retern valve, water pump inserts accumulator through water pipe, non retern valve, this accumulator is an airtight container, pressure sensor device is arranged at its top, this sensing device connects a pressure switch, and the contact of relay inserts automatic controller, and the motor of water pump also inserts automatic controller; Water pipe is drawn in the bottom of accumulator, and it is indoor that this pipe feeds the user.

The preferred version of above-mentioned automatic controller is: insert rectifier D with the 220V power supply through transformer B ₁-D ₄, the output head anode of rectifier is through pressure switch J ₃Contact J _3-1Succeed electrical equipment J ₁An end, simultaneously through J ₁Contact J _1-1Meet J ₂An end, rectifier D ₁-D ₄Negative pole of output end is through R ₁Meet J ₁The other end, it also connects the other end of J2, rectifier D ₁-D ₄Output two capacitor C in parallel ₁, C ₂, the motor D of water pump is through relay J ₂Contact J _2-1, J _2-2Insert the 220V both ends of power, hand switch K is arranged between this power supply and the transformer ₁, K ₂, power supply is parallel with power supply indicator LD, and motor parallel has indicator lamp HD.

Advantage of the present utility model is: 1, liberation labour, and easy to use.2, it is simple in structure that it totally constitutes the little automatic control section of volume, and cost is low.3, simple installation can be positioned on accumulator under the frostproof course on ground, does not take up room.

Fig. 1 is the utility model embodiment overall structure schematic diagram;

Fig. 2 is the circuit theory diagrams of the utility model automatic controller.

The utility model is described in further detail below in conjunction with accompanying drawing.

Can see by Fig. 1, this device is to connect water pump (11) under frozen soil layer on the former well casing (7), the well casing on water pump top has a non retern valve (8), water pump inserts accumulator (13) through water pipe (10), non retern valve (9), this accumulator is an airtight container, pressure sensing probe (3) is arranged at its top, and this sensing probe connects a pressure switch J3, and the contact of relay inserts automatic controller (4).The motor of water pump (12) also inserts automatic controller; Water pipe (1) is drawn in the bottom of accumulator (13), and it is indoor that this pipe feeds the user.(2) be power supply, (5) are leads: (6) are well head, and (14) are the accumulator support.

Can see by Fig. 2, the structure of above-mentioned automatic controller, it is to insert rectifier D with the 220V power supply through transformer B ₁--D ₄, the output head anode of rectifier is through pressure switch J ₃Contact J _3-1Succeed electrical equipment J ₁An end, simultaneously through J ₁Contact J _1-1Meet J ₂An end, rectifier D ₁-D ₄Negative pole of output end is through R ₁Meet J ₁The other end, it also meets J ₂The other end, rectifier D ₁-D ₄Output two capacitor C in parallel ₁, C ₂, the motor D of water pump is through relay J ₂Contact J _2-1, J _2-2Insert the 220V both ends of power, hand switch K is arranged between this power supply and the transformer ₁, K ₂, power supply is parallel with power supply indicator LD, and motor parallel has indicator lamp HD.

When the water level in the accumulator is lower than certain limit, the gas pressure subcritical value in it, pressure switch J ₃Adhesive, its contact J _3-1Closure, then relay J ₁Adhesive, J simultaneously ₁Contact J _1-1Closure, then J ₂Adhesive, relay J ₂Contact J _2-1, J _2-2All closed, then the motor D of water pump starts; Water level is during to certain position, pressure switch J ₃Discharge, the then motor of water pump outage stops pumping.
