Abstract

The invention relates to an automatic water discharging device, which can finish the water discharging task automatically by presetting according to the water discharging plan. The automatic water discharging device is characterized in that a one-way valve is arranged in a pipe; a water inlet of the pipe is provided with a force transferring pipeline to control the opening and closing of a sealing cover; a 90-degree elbow is sheathed at a water outlet end of the pipe; the buoyancy caused by lifting and falling of a floating body along with the liquid level is transferred to the force transferring pipeline; and the purpose of finishing the water discharging task automatically is achieved by presetting according to the water discharging plan.

Description

Automatic tailrace

Affiliated technical field

The present invention relates to a kind of farmland jettison gear, especially can set on request, control the height of field water inlet water level automatically; Can close in (water not into and out of); Can open (designated water level water inlet), can move back (water level is put water on request), accomplish the tailrace of the plan of discharging water according to the needs of field different times.

Background technology

At present, the equipment of discharging water in paddy field, rural area is culvert, mould pipe, bamboo trunk etc., leans on artificial line up to carry out shutoff, excavation, and the person of discharging water is not known after each peasant household's medication the requirement of water and time is caused the phenomenon ubiquity that misplaces water or do not discharge water.

Summary of the invention

In order to overcome existing culvert, manage the confusion that discharges water, the big amount of labour, the present invention provides a kind of tailrace, does not only need manual work to discharge water, and more can preestablish the pass, open, move back according to people's the plan of discharging water, and on purpose discharges water according to plan.

The technical solution adopted for the present invention to solve the technical problems is: the inside at pipe is provided with a slidingtype one way valve or a swing type one way valve (one way valve is made up of end mouth, sealing ring, valve plate, valve plate control line); The outside of the water inlet end of pipe is with filtering screen; Be fixed with the guide-localization pin at the bottom of the mouth of pipe on the mouth; Pasting sealing ring at the bottom of the mouth of pipe on the mouth; Be with seal cover on the guide-localization pin; The seal cover inboard heads on back-moving spring; Fixedly put forth effort to transmit the mouth of pipe of pipeline at the bottom of the water inlet on the mouth, fixedly put forth effort to transmit the line of pipeline on the seal cover.The outside, water side of pipe is with 90 ° of elbows, and the delivery port outside of elbow is with filtering screen.The mouth of pipe that power is transmitted the other end of pipeline is fixed on the fixed head, and fixed head is fixed on the backstay, and the fixed head top has a buoyancy aid to be enclosed within on the backstay; Erect on the buoyancy aid screw rod is arranged; Nut is arranged on the screw rod, and the nut top is with a balancing pole, and bed knife transmits the line of pipeline on the balancing pole.When nut rotates up, transmit in power under the effect of pipeline, gradually to closing, the interior water of water channel this moment can't flow to the paddy field to seal cover, and the water in the paddy field also can't flow back to water channel; When nut is rotated down Δ 1; Seal cover is opened under the effect of back-moving spring gradually, if this moment, the water level in the water channel was higher than the field water level; Just in can inflow pipe; Push slip valve plate or swing type valve plate open, flow in the paddy field, will turn to the side in advance this moment with the delivery port of 90 ° of elbows; Current are normally trickled; When water level rise Δ 1, the buoyancy aid come-up is transmitted pulling Δ 1 on the alignment in the pipeline with power, gradually seal cover is closed; When not having water in the water channel; And the field water level is when consuming gradually; Buoyancy aid descends; The line that power is transmitted in the pipeline is loosening; Back-moving spring is just opened seal cover; Water in the paddy field begins in water channel to flow, but moment current just can promote to make field water can't flow into water channel on the end mouth sealing ring of swing type valve plate or slidingtype valve plate to one way valve; When the water consumption in field will be use up, when pouring water once more in the water channel, just begin automatically again another to the field process that discharges water; The water yield excessive (when particularly " flood " rainy season) when the field; With nut be rotated down to screw rod bottom, directly over the elbow delivery port turned to or side top, or do not rotate; The control line that spurs simultaneously on swing type or the slidingtype valve plate is also fixing, and unnecessary water is emitted from the field.

The invention has the beneficial effects as follows, can be provided with in advance according to the plan of discharging water, accomplish close, limiting the quantity of discharges water, limits the quantity of draining, need the person of discharging water, can not misplace water or do not discharge water.

Description of drawings:

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is vertical section structure (principle) figure of first embodiment of the present invention.

Fig. 2 is water inlet, seal cover position and buoyancy aid, the power of second embodiment of the present invention vertical section structure (principle) figure that transmits the pipeline position (not drawing among figure part and Fig. 1 identical).

The specific embodiment

In Fig. 1, mouth (8), one way valve sealing ring (7), valve plate (9), valve plate control line (10) are formed slidingtype one way valve or swing type one way valve jointly at the bottom of the inside one way valve of pipe; Post sealing ring (3) on the mouth (4) at the bottom of the water inlet of pipe, be inserted with guide-localization pin (1), the pipe of fixing strong transfer tube line (6); Be with seal cover (2) on the guide-localization pin (1), seal cover (2) is gone up the line of fixing strong transfer tube line (6); Be pressed with back-moving spring (5) under the seal cover (2); Mouth at the bottom of the water inlet (4) outside is with filtering screen (20); The outside, water side (11) is with 90 ° of elbows (12), and delivery port (13) outside of elbow (12) is with filtering screen (20); The pipe that power is transmitted pipeline (6) other end is fixed on the fixed head (15), and fixed head (15) is fixed on the backstay (16); Fixed head (15) top has buoyancy aid (14), buoyancy aid (14) to be enclosed within on the backstay (16), and buoyancy aid (14) is gone up to erect has screw rod (17), and nut (19) is arranged on the screw rod (17), and nut (19) top is with balancing pole (18); After passing the aperture on buoyancy aid (14), the balancing pole (18), line in the power transmission pipeline (6) is fixed on the balancing pole (18).

Seal cover in Fig. 2 (2) is the translating type among rotary-type rather than Fig. 1, and back-moving spring (5) is the screw type among V-type rather than Fig. 1, and power is transmitted pipeline (6) and only used one, all the other do not draw part all with Fig. 1 in identical.
