Description

Technical Field

[0001] The utility model relates to the field of agricultural drainage channels, in particular to a junction structure of farmland ditches. Background Art

[0002] Ditches are essential facilities for farmland irrigation and drainage. Agricultural ditches refer to channels that divert water from ditches to various plots of land. In farmland water conservancy water delivery channels, fixed channels are generally divided into four levels: trunk, branch, ditches, and agricultural ditches according to channel functions and scales. Agricultural ditches refer to channels that divert water from ditches to various plots of land. The next level is the ditches used for irrigation or salt washing in various plots of land.

[0003] However, at the intersection of ditches, the change in the direction of water flow will have an impact on the intersection. The current agricultural canals have not taken preventive measures to deal with this phenomenon, making the intersection more susceptible to wear and blockage. The degree of damage and wear at the intersection of agricultural canals is often much higher. Therefore, the maintenance frequency of the intersection is higher, which will consume a lot of manpower and material resources. If the intersection is not repaired in time, it will also affect the normal water supply of the agricultural canal, ultimately leading to a decrease in farmland yields.

[0004] This case was created to solve the above problems. Utility Model Content

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] The utility model provides a farmland ditch intersection structure, such as Figure 1-4As shown, it includes two intersecting ditch bodies 1, forming an intersection center and four intersections, a polygonal guide column 2 is provided at the intersection center, a guide block 3 is provided at the intersection, the guide block 3 is located on the center line of the ditch body 1, and guide grooves 4 are opened on the ditch walls on both sides of the ditch body 1 near the intersection, the guide grooves 4 are connected with the two intersecting ditch bodies 1, and the water flow is diverted by the guide block 3 provided at the intersection. The guide block 3 is streamlined as a whole. In the process of diverting the water flow, the impact of the water flow is dispersed while absorbing part of the impact of the water. After the water flows through the guide block 3, it is affected by the rotating multilateral guide column 2, and the water flow changes its direction of flow, transferring the impact of the water flow from the ditch body 1 itself to the guide block 3 and the multilateral guide column 2, thereby protecting the ditch body 1 itself.

[0022] Reference Figure 3-4 A cylindrical cavity 5 is opened in the guide groove 4, and a circular guide column 6 is arranged in the cylindrical cavity 5. A scoring plate 7 is fixed on the side of the circular guide column 6. The top view surface of the cylindrical cavity 5 is tangent to the top view surface of the guide groove 4. The radius of the circular guide column 6 plus the width of the scoring plate 7 is equal to the radius of the cylindrical cavity 5. The scoring plate 7 is narrowed on the side away from the circular guide column 6.

[0023] As the circular guide column 6 rotates, the paddle 7 is driven to rotate together, thereby sucking the water flow in from the entrance of the guide groove 4. The setting of the guide groove can divert part of the water flow and further resolve the water flow impact at the intersection.

[0024] Reference Figure 1-4 A filter baffle 8 is provided near the intersection of the ditch body 1. The filter baffle 8 is provided in the upper half of the cross section of the ditch body 1. The filter baffle 8 is located between the intersection and the guide groove 4. The filter baffle 8 can intercept the floating objects in the water sheet in the ditch body 1, and then be attracted into the guide groove 4. Under the action of the paddle 7, the floating objects can smoothly pass through the guide groove 4 to the other ditch body 1, avoiding the blockage of the guide groove 4. At the same time, the floating objects also bypass the intersection center, avoiding the accumulation of floating objects in the intersection center.

[0025] The circular guide column 6 and the polygonal guide column 2 are both controlled by a motor, which is arranged below the ditch body 1 .

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
