Irrigation water diversion device

Technical Field

The utility model relates to an irrigation water diversion apparatus belongs to agricultural irrigation technical field.

Background

In agriculture in vast rural areas, water conservancy construction has already been achieved initially, the situation that the agriculture is harvested depending on the day is basically ended, but rural paddy field irrigation is basically finished in a channel water delivery mode, and the channel water delivery mode has the characteristics of large evaporation capacity and relatively low flow rate. In order to solve the problems existing in the traditional ditch water delivery, people adopt a pipeline water delivery mode to replace ditch water delivery. After people adopt the pipeline to carry out the water delivery, often install tee bend and shunt gate valve additional on the pipeline, control the irrigation of paddy field with the mode of control diversion gate valve. When the water supply is controlled by the shunt gate valve, the problem of damage to the paddy field due to overlarge water pressure is easily caused, and even a water pit is flushed out of the outlet of the shunt gate valve; therefore, the existing irrigation diversion valve can not meet the use requirements of farmers.

Detailed Description

The irrigation water diversion device consists of a paddy field water delivery pipeline 1, an overflow valve 2, a reservoir 3, a water stop valve 4 and a sewer 5 (see the attached figure 1 in the specification).

A reservoir 3 is built on the paddy field water delivery pipeline 1; an overflow valve 2 is arranged on a water conveying pipeline 1 of the paddy field at one side of the reservoir 3 (see the attached figures 1 and 2 of the specification).

The overflow valve 2 consists of an assembly sleeve 6, an overflow pipe 7, a sealing turning plate 8 and an overhaul disc 9 (see the attached figure 3 in the specification); the assembly sleeve 6 is arranged on the water delivery pipeline 1 of the paddy field; the assembly sleeve 6 is communicated with the paddy field water delivery pipeline 1; an overflow pipe 7 is arranged on one side of the assembling sleeve 6; the overflow pipe 7 extends to the interior of the water storage tank 3 and is communicated with the water storage tank; when in use, water in the water conveying pipeline 1 of the paddy field enters the reservoir 3 through the assembling sleeve 6 and the overflow pipe 7 to be stored.

The top end of the assembling sleeve 6 is in threaded connection with an access panel 9 (see the attached figure 3 in the specification); the purpose of setting the maintenance plate 9 is as follows: firstly, the upper end of the assembly sleeve 6 is sealed, so that the problem of irrigation water leakage is prevented; secondly, when overflow valve 2 needs to be overhauld, open and overhaul dish 9 and can overhaul overflow valve 2.

The inside of the fitting sleeve 6 is provided with a sealing flange 10; the top of the sealing flange 10 is hinged with a sealing turning plate 8 through a pin; the sealing flap 8 is intermittently connected to the sealing flange 10 in a sealing manner (see the description and the attached figure 3). The purpose of the sealing flap 8 and the sealing flange 10 being arranged in this way is: so that the sealing turnover plate 8 can be kept in sealing connection with the sealing flange 10 under the action of gravity; when the paddy field needs irrigation and the water transmission pipeline 1 of the paddy field is filled with water, the water flow in the water transmission pipeline 1 of the paddy field can break the sealing turning plate 8 and enter the reservoir 3 through the overflow pipe 7 for storage.

A sewer 5 is built at one side of the reservoir 3; when the paddy field is irrigated, irrigation water in the reservoir 3 finally enters the paddy field through the sewer 5. The sewer 5 is in a Z-shaped structure (see the attached figure 1 in the specification); the purpose of arranging the sewer 5 as such is: with "Z" style of calligraphy structure through ditch 5 down, reduce the impact force of irrigation water, make irrigation water can be steady enough to enter into the paddy field and irrigate, avoided the too big emergence of damaging the paddy field problem of current irrigation mode water pressure from this.

A sunshade cover plate (not shown in the specification) is placed at the upper end of the sewer 5; the sunshade apron can protect sewer 5 to avoid debris such as clod to enter into sewer 5, take place the problem of "jam".

The outlet end of the sewer 5 is provided with a spacer grid 14. The spacer grid 14 can separate impurities in the paddy field from the sewer 5, thereby avoiding the problem of blockage caused by the impurities in the paddy field entering the sewer 5.

A water isolating valve 4 is arranged between the sewer 5 and the water storage tank 3 (see the attached figure 4 in the specification). The water-stop valve 4 is composed of an isolation flashboard 11 and a water-stop valve body 12 (see the attached figure 5 in the specification). A water isolating valve body 12 is embedded between the sewer 5 and the reservoir 3; an isolation plugboard 11 is movably inserted in the middle of the water-stop valve body 12; the water stop valve bodies 12 on two sides of the isolation inserting plate 11 are correspondingly provided with water through holes 13. When the isolation inserting plate 11 is manually pulled away, irrigation water in the water storage tank 3 enters the paddy field through the limber holes 13 and the sewer 5, and irrigation work of the paddy field is completed.

When the irrigation water diversion device works, the water isolation valve 4 is firstly opened (namely the isolation flashboard 11 is pulled out); after the water separation valve 4 is opened, water flow in the water conveying pipeline 1 of the paddy field rushes away the sealing turnover plate 8 of the overflow valve 2, enters the water storage tank 3 through the overflow pipe 7, and then irrigation water entering the water storage tank 3 enters the paddy field through the water through hole 13 of the water separation valve 4 and the sewer 5, so that irrigation work of the paddy field is completed.

In the process, the water in the water conveying pipeline 1 of the paddy field firstly overflows into the reservoir 3 after being flushed by the overflow valve 2 assembled on the water conveying pipeline 1, and then the irrigation work of the paddy field is completed through the sewer 5, so that the movement of the water conveying pipeline is relatively smooth, and the problem that the farmland is easily damaged when the water flow in the water conveying pipeline 1 of the paddy field is directly flushed for irrigation is solved.
