Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-standard farmland construction, and in particular to a water channel structure for irrigation of high-standard farmland. Background Technology
[0002] Currently, in the construction of high-standard farmland, irrigation canals are usually made of cast-in-place concrete or precast concrete instead of traditional earthen canals. However, in the existing technology, no matter what structure the canal is made of, silt and garbage are easy to accumulate. The accumulation of silt and garbage will reduce the water conveyance efficiency of the canal.
[0003] Silt and garbage tend to accumulate, especially at bends in waterways. Water flows through bends due to centrifugal force, with a faster flow velocity on the outer side (concave bank) and a slower flow velocity on the inner side (convex bank). Therefore, the outer side has a strong scouring ability, easily carrying away garbage; the inner side has a lower flow velocity and weaker carrying capacity, causing garbage to accumulate on the inner side of the bend.
[0004] Based on the above, this utility model proposes a novel irrigation canal structure for high-standard farmland irrigation, which can effectively improve and solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this invention is to provide a water channel structure for high-standard farmland irrigation, in order to solve the problem of large amounts of silt and garbage accumulating at bends in the water channel, which reduces the water conveyance efficiency of the water channel.

[0008] Furthermore, the straight sections of the water channel structure are composed of multiple straight-type assembly modules assembled continuously, and each bend in the water channel structure is connected and assembled through a bend-type assembly module.

[0010] Optionally, the cross-sections of the straight-line assembly module, the main curve module, and the curve lining module are all inverted trapezoidal.
[0011] Optionally, the height of the grille baffle is flush with the height of the main curve module, and the width does not exceed 1 / 2 of the width of the main curve module.
[0012] Optionally, the grid spacing of the grid baffle does not exceed 0.5cm.
[0013] Optionally, the grille baffle and the opening of the main module of the curve are set at a certain inclination angle, and the value of the inclination angle is in the range of 45 to 90°.
[0014] Furthermore, the tilt angle of the grid baffle is specifically set according to the water flow velocity in the canal: when the water flow velocity is <1.5m / s, the tilt angle is set to 45°; when the water flow velocity is =1.5~2.0m / s, the tilt angle is set to 60°; when the water flow velocity is =2.0~2.5m / s, the tilt angle is set to 75°; when the water flow velocity is >2.5m / s, the tilt angle is set to 90°.

[0026] It should be noted that in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0027] This utility model provides a canal structure for high-standard farmland irrigation. The canal structure is a prefabricated assembly structure, as shown in the attached figure. Figures 1-3 As shown, it includes a straight-line assembly module 1 and a curved-line assembly module 2 connected thereto.
[0028] Specifically, the irrigation canal structure is distributed in a serpentine pattern across the farmland. The straight sections of the canal structure are composed of multiple straight-type assembly modules 1 assembled continuously. Each bend in the canal structure has a bend-type assembly module 2. These bend-type assembly modules 2 are connected at both ends to a straight-type assembly module 1 located at the end of a straight section, thus completing the overall assembly of the canal structure. Therefore, a serpentine irrigation canal structure is formed in the farmland, composed of multiple interconnected assembly modules. Water flows into the canal structure at its inlet, forming a serpentine flow path, facilitating irrigation of the surrounding farmland. It is understood that the straight-type assembly modules 1 and the bend-type assembly modules 2 have equal height and width at their connection points, meaning they are mutually compatible.
[0029] Each of the curved assembly modules 2 includes: a curved main module 21, with an opening on the inner side of the curve; curved lining modules 22, respectively assembled and connected to both sides of the curved main module 21, with one end of each curved lining module 22 assembled and connected to the curved main module 21 and the other end assembled and connected to the straight assembly module 1, and the height and width of the curved lining module 22, the curved main module 21, and the straight assembly module 1 are all equal; and a garbage collection pool 24, connected and configured. At the opening inside the bend of the main bend module 21, the width of the opening is perfectly matched to the width of the opening, and the interior of the waste collection pool 24 is connected to the flow channel of the main bend module 21 through the opening; the grid baffle 23 is set at the connection between the waste collection pool 24 and the opening of the main bend module 21, and is located downstream in the direction of water flow, so as to intercept the waste brought by the water flow at the bend; the water pump 25 is installed inside the waste collection pool 24, and the waste enters the waste collection pool 24 with the water flow during the pumping process.
[0030] like Figure 3 As shown, the height of the grating baffle 23 is flush with the top surface of the main bend module 21, meaning the height of the grating baffle 23 is flush with the top surface of the water channel structure, and the spacing between the gratings of the grating baffle 23 does not exceed 0.5 cm to effectively intercept garbage carried by the water flow. To prevent garbage accumulated at the grating from obstructing the water flow, the width of the grating baffle 23 does not exceed 1 / 2 of the width of the main bend module 21, meaning the width of the grating baffle 23 needs to be less than or equal to 1 / 2 of the width of the water channel structure. Due to centrifugal force, the water flow is slower on the inside of the bend, resulting in a weaker garbage-carrying capacity, causing garbage to accumulate on the inside of the water channel bend. This garbage will be intercepted and collected by the grating baffle 23. On the outside of the bend, the water flow is faster, easily carrying away garbage. If this garbage is not intercepted here, it will flow with the water flow to the next bend of the water channel structure, where it will be intercepted and collected by the next grating baffle 23, thus achieving graded collection of garbage.
[0031] Furthermore, one side of the grating baffle 23 is connected to the garbage collection pool 24 via a snap-fit at the connection point between the garbage collection pool 24 and the opening of the curved main module 21, and is inclined, with the inclination angle α determined during the laying of the water channel. The inclination angle α is the angle between the grating baffle 23 and the opening of the curved main module 21, and its value ranges from 45° to 90°, specifically set according to the water flow velocity in the water channel: when the water flow velocity is <1.5m / s, the inclination angle α is set to 45°; when the water flow velocity is =1.5~2.0m / s, the inclination angle α is set to 60°; when the water flow velocity is =2.0~2.5m / s, the inclination angle α is set to 75°; when the water flow velocity is >2.5m / s, the inclination angle α is set to 90°. When the water flow velocity is low, the water carries less garbage, and a smaller inclination angle α facilitates smooth water flow; when the water flow velocity is high, the water carries more garbage, and a larger inclination angle α helps optimize the interception effect.
[0032] Furthermore, since the grating baffle 23 is connected to the garbage collection pool 24 by a snap-fit, the grating baffle 23 can rotate along the side of the garbage collection pool 24, that is, the tilt angle α can be adjusted according to the actual water flow speed.
[0033] The main bend module 21 is fully open on the inside of the bend. Therefore, the assembly and connection of the bend lining module 22 with the main bend module 21 on the inside of the bend is actually achieved through the assembly and connection with both ends of the garbage collection pool 24.
[0034] A water pump 25 is installed inside the waste collection pool 24. This pump creates a pressure difference, causing the waste in the bend to flow into the waste collection pool 24 along with the water flow. The water pumped out by the pump 25 is then pumped back down the flow channel of the bend-type module 2 through a water pipe, joining the water flow to continue irrigating the farmland. The waste in the waste collection pool 24 is cleaned manually periodically to prevent blockages.
[0035] Furthermore, the water pump 25 is turned on periodically to pump water, that is, to clean the garbage intercepted at the screen once a period of 3 to 5 days. This can prevent a large amount of garbage from accumulating and causing blockage, and also meet the needs of energy saving.
[0036] Each of the straight-line assembly module 1, the main curve module 21, and the curve lining module 22 has a protruding embedded structure on its side. More specifically, for each assembly module, both sides have a protruding structure and a matching slotted embedded structure, respectively. For example, for a straight-line assembly module 1, one side has a protruding structure, and the other side has a matching slotted embedded structure. Therefore, the curve lining module 22 and the main curve module 21, the curve lining module 22 and the straight-line assembly module 1, and the straight-line assembly module 1 and adjacent straight-line assembly modules 1 can all be assembled and connected through the aforementioned protruding embedded structures. Figure 4 As shown, this protruding embedding structure not only ensures that the individual assembly modules align and fit together at the cross-section, but also enhances the robustness of the connections between the modules. After all the modules are assembled, the joints are sealed with concrete.
[0037] In this configuration, the cross-section of each of the straight-line assembly module 1, the curved main module 21, and the curved lining module 22 is an inverted trapezoid, as shown below. Figure 1 and Figure 3 As shown. The trapezoidal cross-section helps reduce water flow resistance, allowing water to flow more smoothly, and can reduce the deposition of silt in the corners of the channel.
[0038] The specific steps for using the aforementioned high-standard farmland irrigation canal structure are as follows:
[0039] S1. Dig trenches of the appropriate size between the fields in the farmland according to the requirements of the drawings;
[0040] S2. Lay the assembly modules of the water channel structure in the ditch. Lay straight assembly modules 1 continuously in the straight section of the ditch and lay curved assembly modules 2 in the bend of the ditch. Assemble the curved lining module 22 in the curved assembly module 2 with the straight assembly module 1.
[0041] S3. After assembly, use concrete to seal the joints of the assembled modules;
[0042] S4. After the water channel is filled with water, due to the centrifugal force, the garbage in the water channel will accumulate on the inside of the bend. At this time, most of the garbage is intercepted by the grid baffle 23 located at the connection between the garbage collection pool 24 and the opening of the bend main module 21. If some garbage is not intercepted, it will continue to move forward with the water flow until it is intercepted by the grid baffle 23 in the bend type assembly module 2 laid at the next bend.
[0043] S5. Every 3 to 5 days, clean up the garbage intercepted at the grid baffle 23. Specifically, turn on the water pump 25 located in the garbage collection pool 24. The water pump 25 starts to pump water. Due to the water pressure, the garbage intercepted at the grid baffle 23 enters the garbage collection pool 24 with the water flow. The water pumped out by the water pump 25 is then pumped back to the downstream of the flow channel through the water pipe.
[0044] S6. The garbage in the garbage collection pool 24 shall be cleaned manually and regularly to prevent the garbage collection pool 24 from becoming clogged.
[0045] In summary, the irrigation canal structure for high-standard farmland irrigation provided by this utility model has the advantages of rapid assembly, simple construction, and the ability to intercept and collect garbage in the water, which can improve the problem of canal siltation at low cost.

Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
