Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, a kind of automatic water supplement scale-type evaporator instructing field irrigation, comprise evaporating dish 1, automatic water-replenishing device, automatic water-replenishing device comprises moisturizing groove 2, moisturizing bucket 3, and the top of moisturizing bucket 3 offers filler, filler is provided with flexible pipe 11, filler and flexible pipe 11 1 aspect can be used for adding water to moisturizing bucket 3, also have ventilation effect on the other hand, the pressure in moisturizing bucket 3 can be made equal with ambient pressure, the water be conducive in moisturizing bucket 3 flows out.Moisturizing bucket 3 is arranged on base 7, and the bottom surface of base 7 is concordant with the outer bottom of evaporating dish 1, and the end face of base 7 is not less than the end face of moisturizing groove 2, and make moisturizing bucket 3 be in eminence, the water be conducive in moisturizing bucket 3 flows out automatically.The periphery of moisturizing bucket 3 is provided with support 8, and moisturizing bucket 3 is fixedly connected with support 8, and the bottom of support 8 is fixedly connected with base 7.The sidewall of moisturizing bucket 3 is vertically provided with rule 4, utilizes rule 4 can read the change of water level in moisturizing bucket 3 intuitively.Moisturizing bucket 3 bottom is provided with delivery port, is provided with liquid-level switch 5 in moisturizing groove 2, and liquid-level switch 5 is preferably float switch, and the water inlet of liquid-level switch 5 is communicated with by the delivery port of conduit 12 with moisturizing bucket 3 bottom.The bottom of moisturizing groove 2 is communicated with by flow-guiding mouth 6 with between evaporating dish 1, and the bottom of flow-guiding mouth 6 is concordant with the inner bottom surface of evaporating dish 1, utilizes flow-guiding mouth 6 that the water level in evaporating dish 1 and moisturizing groove 2 can be made equal.
As to further improvement of the present invention, moisturizing groove 2 is fixedly connected with the outer wall of evaporating dish 1 by the fixed mount being arranged on top, the outer bottom of evaporating dish 1 is concordant with the outer bottom of moisturizing groove 2, above the inner bottom surface that the inner bottom surface of evaporating dish 1 is positioned at moisturizing groove 2 and difference in height is 1 ~ 2cm, under cost-saving prerequisite, this difference in height at least can ensure the water in evaporating dish 1 be evaporated after the foot of liquid-level switch 5 can not contact with the inner bottom surface of moisturizing groove 2.
As to further improvement of the present invention, the sidewall of moisturizing groove 2 offers ventilation hole 9, ventilation hole 9 is positioned at above the water inlet of liquid-level switch 5, utilizes ventilation hole 9 that the pressure with extraneous in moisturizing groove 2 can be made equal, ensures that the water level in evaporating dish 1 and moisturizing groove 2 is equal better.
As to further improvement of the present invention, the sidewall of evaporating dish 1 offers overfall 10, overfall 10 can be one also can be multiple, overfall 10 is concordant with the water inlet of liquid-level switch 5, when the water level in evaporating dish 1 is too high, unnecessary water can be flowed out by overfall 10, and then guaranteed water level can not be too high and exceed the water inlet of liquid-level switch 5, can control the rate of water make-up of moisturizing bucket 3 more accurately.
Operation principle of the present invention is: evaporating dish 1 is identical with the water level of moisturizing groove 2 and when reaching the height of float switch water inlet 4, float switch is in closed condition, when after the water evaporation in evaporating dish 1, moisturizing groove 2, water level decreasing in evaporating dish 1, water level decreasing now in moisturizing groove 2 causes the bottom of float switch ball float, float switch will be opened, water in moisturizing bucket 3 will be added in moisturizing groove 2 by conduit 12, moisturizing groove 2 rises with the water level of evaporating dish 1 simultaneously, when water level rises to the peak level and the height of float switch water inlet that float switch controls again, float switch cuts out, moisturizing bucket 3 no longer moisturizing, if moisturizing bucket 3 is identical with the diameter of evaporating dish 1, in the moisturizing bucket 3 then read by rule 4, the scale of water level decreasing is the depth of water amount that evaporating dish 1 evaporates.If moisturizing bucket 3 is not identical with the diameter of evaporating dish 1, then in the moisturizing bucket 3 read by rule 4, the scale of water level decreasing needs to change into through converting the depth of water amount that evaporating dish 1 evaporates.By the evaporation discharge that moisturizing bucket 3 directly or indirectly obtains, and the relation of crop wager requirements and evaporation discharge, crop wager requirements can be estimated and then calculate duty, instructing field irrigation.Automatic water supplement, saves the artificial time added water to evaporation in the field device, decreases work expenditure; Rule is utilized to read the numerical value of evaporation discharge, intuitive and convenient; This automatic water supplement, reading evaporator intuitively, can promote the practical application of evaporating dish in irrigation and water conservancy, formulates irrigation project by the irrigation quantity estimated, can promote the scientific development of field irrigation, practical, cost is low, install simple to operate, easy to use.
Provide using method of the present invention below: for the drip irrigation crop in Huang-Huai-Hai plain greenhouse by solar heat, the water consumption of temperature indoor crops every day is 1 ~ 3mm, suppose that evaporation discharge is A times of water consumption, then in evaporating dish 1, the evaporation discharge of every day is A ~ 3Amm, suppose that the internal diameter of moisturizing bucket 3 is 1/3 (can amplify the display data of evaporation discharge in moisturizing bucket 3 like this) of evaporating dish 1 internal diameter, then the height of moisturizing bucket 3 decline every day is 9A ~ 27Amm, suppose A=1, then in evaporating dish 1, the evaporation discharge of every day is 1 ~ 3mm, in moisturizing bucket 3, the height of decline every day is 9 ~ 27mm.Irrigate when the cumulative evaporation supposing in evaporating dish 1 is 9mm, then irrigate when the falling head in moisturizing bucket 3 is accumulated as 81mm, only need to utilize rule 4 to read the height of liquid level decline, intuitive and convenient more, save the artificial time added water to evaporation in the field ware 1 simultaneously, decrease work expenditure.
