Description

Technical Field

[0001] This utility model relates to a double-plate farmland sluice gate in the field of farmland irrigation and drainage. Background Technology

[0002] Farmland irrigation and drainage are divided into surface irrigation and deep irrigation: Surface irrigation drains the water from the field before rice transplanting and re-irrigates the field after the seedlings have taken root; deep irrigation drains the water from the topsoil before rice harvesting and re-irrigates the field before the soil is leveled the following year. The bottom of the water inlet in a concrete paddy field embankment is slightly higher than the bottom of the irrigation ditch but slightly lower than the bottom of the topsoil, and it is equipped with a concrete gate. When the gate is raised, all the water in the field is discharged from below; when the gate is lowered, all the water is blocked. This makes it difficult to regulate the water level to meet the different water requirements of rice at different growth stages. Therefore, an earthen dike must be built at the bottom of the water inlet, and the water level is regulated by adjusting the height of the dike, allowing excess water to flow out from above. However, the earthen dike will gradually lower or breach under long-term erosion, just like a soil water inlet, thus losing the advantage of the concrete water inlet's sturdiness. Currently, farmland sluice gates on the market and in patent documents are designed for surface irrigation and drainage. If installed directly at the bottom of such deep water inlets, the sluice gate will be buried by the topsoil when the paddy field is leveled for transplanting, making surface irrigation and drainage impossible. Patent CN202221681546.4, entitled "A Paddy Field Sluice Gate," consists of a square water pipe formed by four square plates. Each end of the water pipe has a vertical plate buried in the topsoil. While this effectively blocks water and soil flow, it also hinders deep irrigation and drainage. The water pipe, positioned above the vertical plates, allows for surface irrigation and drainage and prevents soil erosion at the water inlet, but installing it in a sturdy concrete water inlet is a waste of materials. Furthermore, while the water pipe has a uniform length, the length of the water inlet is not uniform; in short, it is unsuitable for installation in a concrete water inlet. Summary of the Invention

[0003] This utility model provides a double-plate farmland sluice gate, characterized in that it mainly consists of a gate sleeve, a mudguard plate, and a water-blocking plate; the gate sleeve is formed by grooves on the left and right sides and the bottom, slightly higher than the water inlet, with abutment plates on the left and right sides of the grooves; the mudguard plate is square, with a height approximately equal to the depth of the cultivated layer, and has a groove on the back of both sides, with the groove opening facing inward and a side plate outside the groove bottom; the groove, side plate, and groove plate extend upward, slightly higher than the gate sleeve; the middle and top of the side plate have symmetrical plate holes, and are equipped with insert plates; the height of the water-blocking plate is the same as the height of the mudguard plate, and there are pull rods on the upper left and right sides, with vertically arranged water level holes and plugs, and a handle at the top, the handle being slightly higher than the groove; the side plates of the mudguard plate are fitted into the grooves, and the sides of the water-blocking plate and the pull rods are fitted into the grooves. This sluice gate is installed at a deep water inlet, which can perform surface irrigation and drainage and deep irrigation and drainage of farmland, and facilitates the regulation of farmland water levels.

Detailed Implementation

[0005] As shown in the figure, this utility model mainly consists of a gate sleeve 1, a mudguard 2, and a water-blocking plate 3. The gate sleeve 1 is composed of grooves 1.1 on the left and right sides and the bottom, which are slightly higher than the water inlet 7. There are plates 1.2 on the left and right sides of the grooves 1.1. The mudguard 2 is square, and its height is approximately equal to the depth of the cultivated layer. There are grooves 2.1 on the back of both sides of the mudguard 2, with the groove openings facing inwards and side plates 2.2 on the outside of the groove bottom. The grooves 2.1, side plates 2.2, and groove plates 2.3 extend upwards, slightly higher than the gate sleeve 1. The side plate 2.2 has symmetrical holes 2.4 in the middle and slightly below the top, and is equipped with insert plates 4; the height of the water baffle 3 is the same as the height of the mud baffle 2, and there are tie rods 3.1 on the upper left and right sides. The tie rods 3.1 have vertically arranged water level holes 3.2 and are equipped with plugs 5. The top has a handle 3.3, which is slightly higher than the sleeve groove 2.1; the side plate 2.2 of the mud baffle 2 is fitted into the groove 1.1, and the two sides of the water baffle 3 and the tie rods 3.1 are fitted into the sleeve groove 2.1. This type of sluice gate is installed at a deep water inlet, which can perform surface irrigation and deep irrigation and drainage of farmland, and facilitates the regulation of farmland water level. The gate sleeve 1 can be cast together with concrete to the water inlet 7 in the field ridge 6, so that the mounting plate 1.2 is attached to the two sides and bottom of the water inlet 7. When deep irrigation and drainage are needed, mudguard 2 and water-retaining plate 3 can be pulled up above the cultivated layer at the same time. At this time, the water inlet 7 is connected to the ditches in the field and the canals outside the field. The canal water is discharged into the river, and the water in the ditch enters the canal and flows into the river. The river water is pumped into the canal, and the canal water level is higher than the field ditches, so it will irrigate the field. When surface irrigation and drainage are needed, mudguard 2 and water-retaining plate 3 can be pressed down at the same time to block the soil in the cultivated layer. The canal water is discharged into the river, and the surface water in the field enters the canal and flows into the river. The river water is pumped into the canal, and the canal water level is higher than the paddy field, so it will irrigate the field. When water storage is needed, mudguard 2 is used to block the soil in the cultivated layer from below, and water-retaining plate 3 is pulled up to the height of the required water level. Excess water will be discharged from the top of water-retaining plate 3. Insert plate 4 is inserted into plate hole 2.4, which can be used to manipulate mudguard 2 to move up and down; it can be locked above groove 1.1 to fix the height of mudguard 2; insert bolt 5 is inserted into positioning hole 3.2 and locked above sleeve groove 2.1 to fix the height of water baffle 3.
