Abstract
A U-shaped groove portable type water level flowmeter comprises a channel connecting device and a water level flow scale, the channel connecting device includes a U-shaped channel with a set standard fracture surface, a water level flow tube and a communicating pipe, the bottom end of the water level flow tube is sealed, a seal cover is arranged at the upper end of the water level flow tube, the water level flow tube is communicated with the U-shaped channel through the communicating pipe, the water level flow scale includes a scale body and test paper, a scale mark of water depth (H) and a scale mark of flow quantity (Q) are arranged on two sides of the scale body respectively, a test paper slot is longitudinally disposed in the middle of the scale body, the test paper is inserted into the test paper slot, the water level flow scale is placed in the water level flow tube which is communicated with the U-shaped channel, and the water level flow tube is tightly compressed by the seal cover. According to the U-shaped groove portable type water level flowmeter, the problem that an effective metering device is absent caused by the fact that the gradient of the U-shaped channel among field ditches in an irrigation area of a plain is smaller than 1/5000 is solved, the cost is low, the flowmeter is durable, portable, convenient to install and easy to operate, a plug and play design is reasonable, structure technical parameters are subjected to an irrigation area field test and can meet requirements of irrigation area water measurement devices, the water measurement accuracy is high, and the flowmeter has high popularization and application values.
Description
Technical field
The present invention relates to agriculture irrigated area water measure equipment, particularly relate to and be fit to the Plain Irrigation District channel than the U-lag formula stage-discharge meter that falls less than 1/5000.
Background technology
The irrigation water inadequate resource has become the key factor of restriction agricultural development, and water-saving agriculture is the inevitable choice of the future of agriculture development, and its center is to reduce water yield waste, improves WUEL.The irrigated area water gaging can calculate the water source timely and accurately and introduce the canal system and the water yield of distributing to channels at different levels and each water unit; Can analyze the water delivery loss of channels at different levels in view of the above; With transformation on economy of water cousumption foundation is provided for continuing of irrigated area is supporting; Can accurately estimate the water-saving result of various measures, promote the popularization of water saving experience greatly.
The irrigated area water gaging is that the irrigated area provides foundation by the irrigated area charge to charging by water consumption, is to promote water saving through economic means, carries out the pacing items of quota water supply, excess price markup.Simultaneously can also avoid broad irrigation to a certain extent, reduce seepage effectively, rationally control underground water table, alleviate the secondary salinization of soil of soil, can reduce nitrogen phosphorus leaching loss simultaneously, alleviate widespread pollution from the overuse of fertilizers and pesticides in rural area and carrying capacity of environment.
The irrigated area canal water gauging only is metered into this one-level of lateral canal, adopts below the lateral canal and presses the equal shunt volume of area, and main cause is that the field ditch number is many, lacks effectively and the low water measure equipment of cost.For scientific and reasonable metering mu water consumption, promote the development of water-saving irrigation technique, also corresponding support equipment should arranged aspect the field ditch water gaging.It is little that Plain Irrigation District field ditch principal feature is that the channel ratio falls, and is generally 1/5000～1/10000.The existing water measure equipment that is fit to the U-shaped canal water gauging in " irrigation canal system water gaging standard " like para-curve aditus laryngis flume and measuring flume with straight wall, is applicable to that the U-shaped channel is minimum than reducing to 1/1500, can't use in Plain Irrigation District.Be scientific and reasonable metering mu water consumption, promote the development of water-saving irrigation technique, seem particularly important in the research and development of field ditch water measure equipment.
Summary of the invention
The technical matters that the present invention will solve lacks effective dose wetting system problem in order to solve the Plain Irrigation District channel than the U-shaped channel that falls less than 1/5000, and the portable stage-discharge meter of a kind of U-lag that provides.
The technical scheme that adopts is:
The portable stage-discharge meter of U-lag is made up of channel coupling arrangement and stage-discharge chi.Described channel coupling arrangement comprises U-shaped channel, stage-discharge pipe and the communicating pipe of the standard section of a setting.The bottom sealing of stage-discharge pipe, the upper end is provided with capping, and said stage-discharge pipe is through being communicated with the U-shaped channel communicating pipe.Described stage-discharge chi comprises that both sides are respectively equipped with chi body, the test paper of depth of water H scale mark and flow Q scale mark.Chi body central longitudinal is to being provided with the test paper slot, and test paper is inserted in the test paper slot.In the stage-discharge pipe that described stage-discharge chi is put into the U-shaped channel is communicated with, and compress with capping.
The chi body of above-mentioned depth of water H scale mark and flow Q scale mark, its depth of water H scale unit is cm, flow Q scale unit is L/S.
Above-mentioned stage-discharge pipe and the rectangular tube that communicating pipe is 40 * 30mm.
The above-mentioned communicating pipe inlet end that is connected with the U-shaped channel is provided with screen pack.
The invention solves the unmeasurable difficult problem of Plain Irrigation District field ditch U-shaped channel; It is low, durable, portable, easy for installation, simple to operate to have cost; Plug and play is reasonable in design, and its structure technology parameter all satisfies irrigated area water measure equipment requirement through the irrigated area site test; The water gaging precision is high, has higher popularization and application values.

Embodiment
The portable stage-discharge meter of U-lag is made up of channel coupling arrangement and stage-discharge chi 5.Described channel coupling arrangement comprises U-shaped channel 1, stage-discharge pipe 4 and the communicating pipe 3 of the standard section of a setting.The sealing of the bottom of stage-discharge pipe 4, the upper end is provided with capping 6, said stage-discharge pipe 4 is through being communicated with U-shaped channel 1 communicating pipe 3, communicating pipes 3 inlet end establish screen pack 2, stage-discharge pipe 4 and be the rectangular tube of 40 * 30mm communicating pipe 3.Described stage-discharge chi 5 comprises that both sides are respectively equipped with depth of water H scale mark 8, unit is that cm and flow Q scale mark 7, unit are chi body 9, the test paper 10 of L/S.Chi body 9 central longitudinal are to being provided with the test paper slot, and test paper 10 is inserted in the test paper slot, are used for showing the depth of water in the channel coupling arrangement.In the stage-discharge pipe 4 that said stage-discharge chi 5 is put into U-shaped channel 1 is communicated with, and compress the portable stage-discharge meter of formation U-lag with capping 6.
During measurement, water flows through U-shaped channel 1, and water was got in the stage-discharge pipe 4 by communicating pipe 3, directly the depth of water was presented on the test paper 10, and its test paper has indiffusible characteristics in the 1min.Theoretical derivation by the depth of water calculates corresponding flow, looks into flow Q mark according to depth of water H mark correspondence, draws U-lag water-carrying section flow: L/S.
