[0038] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] like Figures 1 to 7 As shown, this embodiment proposes a prefabricated integrated field overflow irrigation channel, including a channel body 1 arranged in the field 5, and a water flow channel 13 is provided inside the channel body 1. In this embodiment, the cross-sectional shape of the channel body 1 can be U-shaped, and the channel body 1 is divided into an above-ground part and an underground part, which is a semi-embedded structure. The underground part is buried in the field 5, and the part exposed to the ground is the above-ground part; a plurality of overflow ports 11 arranged at intervals are correspondingly opened on the channel walls on both sides of the above-ground part along the length direction, and the overflow ports 11 are used as overflow ports. The overflow ports 11 are connected to the water flow channel 13, and when the water level in the water flow channel 13 is full, the water can flow out through the overflow ports 11; the overflow port 11 is arranged above the ground; an opening and closing structure 3 for realizing the opening or closing of the overflow port 11 is provided at the overflow port 11. When the overflow port 11 is opened, the water in the overflow channel can flow to the field through the overflow port 11 to realize irrigation.
[0040] As a feasible solution, the opening and closing structure 3 is a ball valve, and the ball valve is sealed and connected to the overflow port 11, and can be fixed by means of sealing adhesive bonding.
[0041] Considering that the adhesive fixation method is inconvenient to disassemble and assemble, the opening and closing structure 3 can also be in the following structural form: the opening and closing structure 3 includes an overflow pipe 31, a boss 34 is fixedly provided on the pipe wall of the overflow pipe 31, and a first sealing ring 35 and a second sealing ring 33 are sleeved and connected on the pipe wall, and the first sealing ring 35 is positioned between the boss 34 and the outer wall of the channel wall; the overflow pipe 31 is provided with a threaded section, and a pressure plate 32 is threadedly connected to the threaded section, and the second sealing ring 33 is positioned between the pressure plate 32 and the inner wall of the channel wall; a clamping space for clamping the channel wall is formed between the boss 34 and the pressure plate 32, and the first sealing ring 35 and the second sealing ring 33 are used to ensure sealing; and it also includes an end cap 36 for blocking the overflow pipe 31, and the end cap 36 is threadedly connected to the end of the overflow pipe 31. When overflow is required, the end cap 36 only needs to be unscrewed. The opening and closing structure 3 adopts structures such as the overflow pipe 31, the end cap 36, and the pressure plate 32, which are convenient for disassembly and installation, and have low manufacturing costs.
[0042] The end cover 36 can be arranged outside the channel body 1 or inside the channel body 1. In the present embodiment, it is preferably arranged inside the channel body 1 because this can reduce the exposed length of the overflow pipe 31 and the occupied space to avoid affecting the mechanical operation and reduce the possibility of damage, and also play a role in protecting the end cover 36.
[0043] In this embodiment, the other end of the overflow pipe 31 is flush with the outer edge of the boss 34 , which is simple and beautiful.
[0044] In this embodiment, at least one end of the channel body 1 is provided with a detachable water baffle 45, which plays the role of blocking the channel body 1. Both ends of the water baffle 45 can be set to be detachable for easy disassembly and assembly; at least one first hole is set on the water baffle 45; it also includes a support plate 41, the two ends of the support plate 41 are positioned and clamped at the pipe wall of the corresponding overflow pipe 31, the support plate 41 is provided with a second hole corresponding to the first hole, the first hole and the second hole are penetrated with a tension screw 42, and the two ends of the tension screw are threadedly connected with a nut 43, one of the nuts 43 is positioned and pressed on one side of the support plate 41, and the other nut 43 is positioned and pressed on one side of the water baffle 45, and the tension screw 42 and the nut 43 connect the water baffle 45 and the support plate 41 as a whole. The tension screw 42 and the support plate 41 form a connecting member 4, which realizes the positioning and fixing of the water baffle 45.
[0045] In order to facilitate the positioning of the support plate 41 , in the present embodiment, both ends of the support plate 41 are provided with clamping grooves, which can be clamped on the wall of the overflow pipe 31 , and the clamping grooves are semicircular structures.
[0046] In order to facilitate fixation, the support plate 41 is also fixedly welded with a sleeve 44 , and the tension screw 42 can pass through the sleeve 44 , and the sleeve 44 plays a guiding and supporting role.
[0047] In this embodiment, a cover plate 2 is pressed on the top of the channel body 1. The cover plate 2 is a grate-shaped structure. The setting of the cover plate 2 can form a passage for people to walk conveniently.
[0048] In order to improve the overall strength, the outer wall of the channel body 1 is provided with a plurality of reinforcing ribs 12 along the length direction.
[0049] The channel body 1 and the reinforcing ribs 12 are prefabricated in an integrated manner, processed and manufactured in a factory, and transported to the site for installation. The channel body 1 can be a multi-section assembly style for easy installation.
[0050] Working principle:
[0051] At the original ridge position, a trench is dug downward to form a groove for installing the channel body 1, and then the channel body 1 is installed, and then the opening and closing structure 3 is installed at the overflow port 11, and the water retaining plate 45 is installed at the end of the channel body 1. The installed channel body 1 can be used as a ridge to replace the traditional ridge without changing the original field planting area, and the setting of the cover plate 2 can form a passage for people.
[0052] When irrigation is needed, irrigation water enters the channel body 1 from the outlet of the upper canal system or the well, fills the water trough 13, and overflows through the overflow port 11 on the ground part of the channel body 1 to achieve field irrigation. Users can determine the number of overflow ports 11 to be opened according to the outlet flow and the length of the field to achieve small field irrigation and save irrigation water.
[0053] The irrigation channel can control the two left and right ridges, dividing the original longer field into multiple small plots to realize small plot irrigation, which can save irrigation water and effectively solve the current problems of large water consumption in ridge irrigation, high labor consumption in ridge irrigation, and large investment in micro-irrigation.
[0054] Application results:
[0055] This device integrates the three functions of water delivery channel, irrigation channel and field ridge. Compared with drip irrigation applied to field crops, this irrigation channel does not require large-scale transformation of the fields and has a low investment cost. Compared with high-pole sprinkler irrigation, this irrigation channel does not affect the operation of large machinery and has high practicality.
[0056] The irrigation channel can be produced on a large scale in a prefabricated manner and can be semi-embedded in the field, with a simple construction process.
[0057] After a period of use, impurities such as silt and sand will inevitably accumulate in the channel body 1. When cleaning is needed, the tension screw 42 is disassembled, the water baffle 45 is disassembled, and the silt inside the water trough 13 can be easily washed away by water flow to ensure the normal use of the irrigation channel. The desilting process of the device is also very convenient and easy to maintain and clean.
[0058] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
