A rice field partition water diversion distribution device

Abstract

This utility model discloses a paddy field zoned water diversion and distribution device, relating to the field of paddy field irrigation canal technology. It includes a main irrigation canal with several branch irrigation canals connected to both sides. A closure assembly is provided between the main irrigation canal and the branch irrigation canals. A partition is installed between the inner walls of both sides of the main irrigation canal. A water-fertilizer pipe is placed on the upper part of the partition. Several water-fertilizer branch pipes are fixedly connected to both sides of the water-fertilizer pipe, and a regulating valve is installed on each water-fertilizer branch pipe. The paddy field zoned water diversion and distribution device, by setting up the partition, separates and supports the water-fertilizer pipe, thus preventing the water-fertilizer pipe from being submerged in the main irrigation canal, avoiding water flow erosion of the water-fertilizer pipe surface, and thereby reducing wear on the water-fertilizer pipe surface. Simultaneously, it also prevents silt in the main irrigation canal from obstructing the water flow (due to water-fertilizer pipe blockage), thus effectively improving the practicality of the paddy field zoned water diversion and distribution device.

Description

Technical Field

[0001] This utility model relates to the field of paddy field irrigation canal technology, specifically a paddy field zoned water distribution device. Background Technology

[0002] Paddy fields are a core concept in agronomy, referring to cultivated land systems specifically used for rice cultivation, possessing multidimensional value in agriculture, ecology, and culture. As an important component of constructed wetlands, paddy fields form sustainable ecosystems through the interaction of food chains such as algae, fish, and microorganisms, providing habitats for wildlife and significantly enhancing biodiversity. Rice cultivation requires a large amount of water, so irrigation ditches are typically dug on one side of the paddy field to divert water, and branch ditches are dug between the main irrigation ditches and the paddy fields to introduce water from the main irrigation ditches into the paddy fields, thus achieving the effect of zoned water diversion for the paddy fields.

[0003] In the prior art, the patent announcement number CN211558002U discloses a double-pipe high-pressure integrated water and fertilizer canal for paddy fields, including a canal and a water and fertilizer pipe; the canal adopts a cylindrical structure made of impermeable material, with one end open and the other end closed, and a number of water intake branch pipes are arranged at intervals on one side or opposite sides of the canal along the length of the canal; the water and fertilizer pipe is arranged along the length of the canal in the water direction, and a number of water and fertilizer branch pipes corresponding to the water intake branch pipes are arranged along the length of the water and fertilizer pipe, and the water and fertilizer outlet of the water and fertilizer branch pipe is connected to the corresponding water intake branch pipe;

[0004] Currently, to improve irrigation efficiency in paddy fields, water pipes are placed on existing irrigation ditches, and water pumps are used to deliver water for integrated water and fertilizer management. However, this method requires placing the water pipes inside the ditches, which can increase the difficulty of cleaning. For example, when cleaning debris from the ditches, care must be taken to avoid damaging the pipes, or the pipes may need to be removed from the ditches before cleaning. This also slows down the water flow, increasing the risk of sediment and impurities accumulating and causing siltation. Furthermore, the pipes are subjected to scouring and friction from the water flow. Especially if there is sediment or other impurities in the ditches, it will exacerbate pipe wear. Long-term wear can damage the pipe surface and even cause leaks, thus reducing the practicality of the dual-pipe high-pressure integrated water and fertilizer canal in the paddy field zoned water distribution system. Utility Model Content

[0005] The purpose of this invention is to provide a paddy field zoned water diversion and distribution device to solve the problem of the practicality of existing paddy field zoned water diversion and distribution devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paddy field zoned water distribution device, including a main water channel, several water diversion branch channels connected to both sides of the main water channel, a closing component provided between the main water channel and the water diversion branch channels, a partition provided between the inner walls on both sides of the main water channel, a water and fertilizer pipe placed on the upper part of the partition, several water and fertilizer branch pipes fixedly connected to both sides of the water and fertilizer pipe, and a regulating valve provided on the water and fertilizer branch pipe.

[0008] Preferably, the partition includes a supporting base plate, on the bottom of which a linear array of supporting crossbars is fixedly arranged. Horizontal reinforcing bars are pre-embedded in the supporting crossbars. Two vertical reinforcing bars are pre-embedded inside the supporting base plate, with the vertical reinforcing bars resting on top of the horizontal reinforcing bars. An arc-shaped groove is provided at the top of the supporting base plate, and the supporting crossbars are placed on the bottom wall inside the groove.

[0009] Preferably, grooves are formed on the inner walls of both sides of the water diversion branch canal. The closing assembly includes a closing plate, which is rotatably connected between the inner walls of the two grooves. Two pull ropes are fixedly installed on the side wall of the closing plate. A storage rod is fixedly wound around the movable end of the pull rope. Mounting seats are rotatably fitted on both ends of the storage rod. The mounting seats are installed on the upper part of the water diversion branch canal. A limiting assembly for locking the rotation of the storage rod is provided on the mounting seats.

[0010] Preferably, the limiting component includes a pin, and a turntable is fixedly sleeved at both ends of the storage rod. A through first hole is opened at the off-axis center of the turntable, and a second hole distributed in a circumferential array is opened at the off-axis center of one side of the mounting base.

At the same time, it can also prevent the water flow speed from being affected by silt in the main water channel (blocked by the water and fertilizer pipes). Therefore, it can effectively improve the practicality of the paddy field zoned water diversion and distribution device.

[0015] 2. This application reduces the cost of erecting water and fertilizer pipes and improves the stability of the water and fertilizer pipe support by setting up prefabricated partitions. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a paddy field zoned water diversion and distribution device, including a main water channel 1, several water diversion branch channels 2 connected to both sides of the main water channel 1, a closing component 3 between the main water channel 1 and the water diversion branch channels 2, a partition 4 between the inner walls of both sides of the main water channel 1, a water and fertilizer pipe 5 placed on the upper part of the partition 4, several water and fertilizer branch pipes 6 fixedly connected to both sides of the water and fertilizer pipe 5, and a regulating valve installed on the water and fertilizer branch pipes 6.

[0024] Specifically, one end of the water-fertilizer pipe 5 is fixedly connected to a water pump, which is placed in a water source. The water source can be a pond with water or an artificially constructed pool. Fertilizers such as chemical fertilizers can be added to the pool. The other end of the water-fertilizer pipe 5 is placed on the end of the water diversion branch canal 2. The main water channel 1 and the water diversion branch canal 2 are formed by excavating water diversion channels on site, and erecting formwork and pouring concrete on the inner walls on both sides and the bottom wall of the water diversion channels. Reinforcing steel bars can be added to the concrete to form the main water channel 1 and the water diversion branch canal 2.

[0025] like Figure 1 and Figure 5 As shown, a placement trough 101 and a water passage trough 102 are sequentially arranged from top to bottom in the main water channel 1;

[0026] Specifically, the inner diameter of the bottom opening of the placement trough 101 is larger than the inner diameter of the top opening of the water passage trough 102, while the length of the support crossbar 402 is smaller than the inner diameter of the bottom opening of the placement trough 101, but larger than the inner diameter of the top opening of the water passage trough 102.

[0027] like Figure 4 As shown, the partition 4 includes a supporting base plate 401. A linear array of supporting crossbars 402 is fixedly installed at the bottom of the supporting base plate 401. A transverse steel bar 403 is embedded in the supporting crossbar 402. Two vertical steel bars 404 are embedded inside the supporting base plate 401. The vertical steel bars 404 are placed on the upper part of the transverse steel bars 403. An arc-shaped groove is provided on the upper part of the supporting base plate 401. The supporting crossbars 402 are placed on the bottom wall inside the placement groove 101.

[0028] Specifically, the support base plate 401 and support crossbar 402 are prefabricated using molds. The support base plate 401 and support crossbar 402 are cast in one piece using concrete, in which vertical steel bars 404 and horizontal steel bars 403 are pre-embedded.

[0029] like Figure 4 As shown, grooves are formed on the inner walls of both sides of the water diversion branch canal 2. The closing component 3 includes a closing plate 31, which is rotatably connected between the inner walls of the two grooves. Two pull ropes 32 are fixedly installed on the side wall of the closing plate 31. A storage rod 33 is fixedly wound around the movable end of the pull rope 32. Both ends of the storage rod 33 are rotatably fitted with mounting seats 34. The mounting seats 34 are installed on the upper part of the water diversion branch canal 2. A limiting component 35 for locking the rotation of the storage rod 33 is provided on the mounting seat 34.

[0030] Specifically, the closing plate 31 is inclined, and the inner wall of the groove is inclined. By using the inclination of the closing plate 31, the water pressure on the closing plate 31 is increased, thus increasing the sealing effect of the closing plate 31 on the water diversion branch channel 2. A fixing sealing ring can be added to the outside of the closing plate 31, or soil can be added to one side of the closing plate 31 to increase the sealing performance of the closing plate 31.

[0031] like Figure 4 As shown, the limiting component 35 includes a pin 351, and a turntable 352 is fixedly sleeved on both ends of the storage rod 33. A through first hole 353 is opened at the off-axis center of the turntable 352, and a second hole 354 distributed in a circular array is opened at the off-axis center on one side of the mounting base 34. The pin 351 is inserted between the first hole 353 and the corresponding second hole 354.

[0032] like Figure 4 As shown, the pin 351 includes two thick blocks, and a thin rod is fixedly disposed between the two thick blocks;

[0033] Specifically, the outer diameter of the thin rod is smaller than the inner diameter of the second through hole 354 and the first through hole 353, and the outer diameter of the thin rod is smaller than the outer diameter of the thick block, and the outer diameter of the thick block is smaller than the inner diameter of the second through hole 354 and the first through hole 353. The length of the thin rod is equal to the sum of the widths of the mounting base 34 and the turntable 352.

[0034] like Figure 4 As shown, a counterweight plate 7 and a tie ring 8 are fixedly installed on one side of the closed plate 31, and the movable end of the pull rope 32 is fixed on the tie ring 8;

[0035] Working principle: Multiple support base plates 401 are placed on the placement trough 101, and water and fertilizer pipes 5 are placed on the support base plates 401. Water and fertilizer branch pipes 6 on the water and fertilizer pipes 5 are placed on the water diversion branch canal 2. One end of the main water canal 1 is connected to the water source. Irrigation water is diverted by the main water canal 1. When one or more water diversion branch canals 2 need to be used, simply rotate the storage rod 33. The storage rod 33 will store two pull ropes 32. The pull ropes 32 are used to pull up the movable end of the closing plate 31, thereby opening the water diversion branch canal 2. Then, the pin 351 is inserted between the first through hole 353 and the corresponding second through hole 354 that are connected to each other, thereby fixing the storage rod 33. Irrigation is carried out using the main water canal 1 and the water and fertilizer pipes 5.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
