Abstract

The utility model relates to an automatic water intaking unit, which is composed of a water pump, a water box, a check valve, a float switch, an electromagnetic valve, a break valve, an air release valve, a water intaking pipe, a water draining pipe and an adjutant water supplying pipe. The check valve is arranged on the front end of the water intaking pipe, and the electromagnetic valve is arranged on the rear end of the water intaking pipe and is communicated with the top of the water box; the water draining pipe and the break valve are arranged on the bottom of the water box; the check valve and the water pump are arranged on the lower end of the water supplying pipe, and the water supplying pipe is communicated with the top of the water box; the float switch is movably connected to a connecting rod and the connecting rod is fixed to the top face of the water box. The automatic water intaking unit with a low energy consumption can intake water automatically and continuously.

Description

Automatic water diversion device

The utility model relates to a kind of automatic water diversion device, is used for the diversion of agricultural irrigation and domestic water.

Existing water diversion apparatus is seen Fig. 4, comprises water pump 17 and intake-discharge pipe road 15 and 16.Its deficiency is: need consumed power.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of few automatic water diversion device that consumes energy is provided.

The purpose of this utility model can reach by following measure: the utility model is made up of water tank, water pump, safety check, switch, electromagnetic valve, stop valve, bleed valve, intake-discharge pipe and auxiliary water-feeding tube, the intake pipe front end has safety check, the intake pipe rear end has electromagnetic valve to be communicated with tank top, and water tank bottom has waste pipe and stop valve.There are safety check and water pump in the water pipe lower end, and the upper end is communicated with tank top, and switch is movably connected on the connecting rod, and connecting rod is fixed in the water tank end face.The water tank end face has bleed valve.

The drawing of accompanying drawing is described as follows:

Fig. 1 is total figure of the present utility model;

Fig. 2 be the A of Fig. 1 to view, switch is an enlarged view;

Fig. 3 is that the B of Fig. 1 is to view;

Fig. 4 is the figure of prior art.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: referring to Fig. 1-Fig. 3, the water surface is stretched into 2 times in intake pipe 1 lower end, and the intake pipe front end has safety check 14, and the intake pipe rear end has electromagnetic valve 10 to be communicated with water tank 3 end faces.Water tank bottom has waste pipe 5 and stop valve 4, can adorn or not adorn waste pipe behind the stop valve 4.Water pipe 8 is seen Fig. 3, is auxiliary water supply usefulness, and its lower end is for placing undersurface water pump 6, pump 6 adopts submersible pumps, and safety check 14 is arranged at its top, and the effect of safety check 14 is that pump 6 stops that water reflux in the pipe 8 when cutting out, thereby the assurance tank seal, water pipe 8 is communicated with the water tank end face.Switch 9 is to supply switch water pump 6 and switch electromagnetic valve door 10 usefulness, there is connecting rod 11 in switch central authorities, the connecting rod top is fixedly connected on the water tank end face, switch can slide up and down on connecting rod, there is adjustable baffle plate 7 the connecting rod lower end, according to using needs to adjust the stroke size that switch slides up and down.The water tank end face is equipped with bleed valve 13.

During diversion, open bleed valve earlier and shut stop valve 4, start auxiliary water supply pump 6 then, in water tank, pour water, close bleed valve after treating to emit water on the bleed valve, at this moment, the water surface 12 rises and bumps to end face together with the switch upper contact head and controls termination of pumping and opens solenoid valve door.Open stop valve, water in the water tank is discharged from waste pipe and stop valve owing to conduct oneself with dignity, and makes water tank end face trend vacuum like this or produces vacuum cavity.At this moment, the hydraulic pressure of intake pipe lower end is greater than water tank end face hydraulic pressure, and with hydraulic pressure to the water tank end face, river is caused in the water tank from the river face continuously, discharge supply from waste pipe then and use.If the water tank water surface descends, contact moves down and touches baffle plate 7 under the switch with the water surface, and at this moment, switch control electromagnetic valve door is closed to open with control of pump and supplied water water tank, treats that water tank fills water, switch control termination of pumping and close electromagnetic valve.Like this, under unserviced situation, can guarantee that ceaselessly diversion is for using.

The utility model contrast prior art has following advantage: can less consume electric energy and really Protect ceaselessly automatic water-leading.
