Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting technology, and more particularly to a farmland irrigation system based on a rainwater harvesting module. Background Technology

[0002] Traditional irrigation methods suffer from low water resource utilization and high costs for drought resistance and seedling protection. Rainwater harvesting modules, as supporting facilities for water-saving irrigation systems, can efficiently store natural rainfall through a buried modular structure. The collected rainwater is filtered and purified before being connected to the drip irrigation and fertigation systems that are already widely used in farmland. This not only stores surplus water resources and reduces surface runoff and water and fertilizer loss during the rainy season, but also provides clean irrigation water for key stages such as seedling establishment and vigorous growth during the dry season, significantly improving the self-sufficiency of farmland water resources. Compared with traditional concrete rainwater harvesting facilities, it also has the advantages of convenient construction, high space utilization, and adaptability to complex farmland terrain. It can effectively reduce the labor and water intake costs of farmland irrigation, while ensuring stable soil moisture at different growth stages, thus helping to improve the yield and quality of agricultural products.

[0003] When existing rainwater harvesting modules are put into actual use, the supporting columns of traditional modules are mostly simple hollow columns. Under the heavy pressure of deep backfill and ground objects, the harvesting modules are prone to buckling deformation, which can easily lead to the collapse of the module foundation. Since all modules are assembled by snap-fit, when a module deforms and collapses, it is necessary to dig it out from the top and disassemble the entire matrix module that is snapped together one by one for maintenance. This process is labor-intensive and costly. Summary of the Invention

[0004] This invention discloses a farmland irrigation system based on a rainwater harvesting module, aiming to solve the technical problems that existing rainwater harvesting modules need to be improved in terms of structural strength and ease of operation when put into actual use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A farmland irrigation system based on a rainwater harvesting module includes several evenly distributed base plates. Several rows of evenly distributed columns are fixedly installed on the outer side of the base plates. Several vertically distributed base plates are stacked sequentially through the columns. The interior of each column is provided with a reinforcement mechanism to improve the structural strength of the entire harvesting module. The reinforcement mechanism includes a reinforcement member fixedly installed in the middle of each column. Each column has an end slider and a tail slider slidably installed at its upper and lower ends, respectively. The reinforcement member, the end slider, and the tail slider are all cross-shaped structures. The vertically stacked columns and base plates are engaged and connected to each other through the outwardly sliding end slider and the tail slider. The substrate is provided with a series mechanism in the middle to facilitate workers to perform fixed-point maintenance. The series mechanism includes a sleeve in the middle of each substrate. Several sleeves are stacked and symmetrically distributed in the vertical direction, and a steel bar is installed through them. A base is installed at the bottom of the steel bar. The base is distributed at the bottom of the lower substrate. A nut is installed at the top of the steel bar. The nut is pressed against the top of the upper substrate.

[0006] By incorporating a cross-shaped end sliding member, tail sliding member, and reinforcement structure into an existing farmland irrigation system based on rainwater harvesting modules, and utilizing these three components supported within the column, a cross-shaped lining is installed inside the traditional hollow column. This transforms the column into a composite structure of "tube + cross core," converting the single hollow tube wall stress of the traditional column into a grid-like stress system. This significantly improves compressive strength, and the cross-shaped flanges effectively prevent buckling deformation of the column under lateral earth pressure. Simultaneously, the water collected at the column base... The stress is distributed to the four flanges to prevent root cracking. The end and tail sliding parts are not only structural reinforcements but also male connectors for vertical connection, which can connect the stacked substrates in the vertical direction in sequence. This design integrates the connection structure, does not occupy extra space, and the connection force is directly applied to the load-bearing core, resulting in more reasonable stress distribution and more stable connection. At the same time, a series mechanism with steel bars as the main body is set up, which can be pulled out in a coordinated manner during maintenance, so that the replacement can be completed without damaging the overall matrix, which greatly improves the convenience of traditional module maintenance.

[0007] In a preferred embodiment, the top and bottom of the column are respectively provided with an end sliding groove and a tail sliding groove. The end sliding member is slidably distributed inside the end sliding groove, and the tail sliding member is slidably distributed inside the tail sliding groove. The top of the end sliding groove is provided with a through opening, and adjacent end sliding members in the vertical direction will slide and engage inside the through opening.

[0008] By incorporating an existing farmland irrigation system based on rainwater harvesting modules, a cross-shaped structure of end sliding members, tail sliding members, and reinforcement components is added. These three components are supported inside the column, and a cross-shaped liner is installed inside the traditional hollow column. The end sliding members and tail sliding members, which slide in the end sliding groove and tail sliding groove respectively, can engage adjacent base plates and columns in a self-moving manner. This structure serves as both a reinforcement and a male connector for vertical connection, enabling the sequential connection of base plates stacked vertically, resulting in high functionality.

[0009] In a preferred embodiment, a side plate is installed between two substrates distributed vertically, the side plate wrapping around the outside of the entire collection module. Each side plate has a secondary dovetail groove and a secondary dovetail piece symmetrically arranged on its outer side. Two adjacent side plates in the horizontal direction are connected by the secondary dovetail groove and the secondary dovetail piece. Dovetail combination grooves are symmetrically opened between the upper and lower sides of each side plate and the outer side of the substrate. Dovetail assembly pieces are engaged and fixed inside the dovetail combination grooves, and the side plates and the substrates are fixed by the dovetail assembly pieces.

[0010] By additionally setting a side plate structure on the outside of the substrate, and using the cooperation of the secondary dovetail groove and the secondary dovetail piece, and the cooperation of the dovetail combination groove and the dovetail combination piece, the side plates are connected to each other and the substrates are connected to each other, thereby maintaining the sealing performance of the collection module when storing water and maintaining the integrity of the equipment operation.

[0011] A construction method for a farmland irrigation system based on a rainwater harvesting module includes the following steps; S1: Workers excavate a foundation pit along the ground according to the set dimensions, and hoist the entire module to be assembled into the prepared foundation pit; S2: At this time, the workers follow the markings of the foundation pit and stack multiple substrates in the vertical and horizontal directions with the support columns and shake them slightly. When stacked in the vertical direction, the substrates will fit with the adjacent substrates and the columns will fit with the adjacent columns. At the same time, the end sliding parts and the tail sliding parts located inside the columns will slide vertically by their own weight and engage with the adjacent substrates and columns. S3: When stacking the lower substrate, a base needs to be placed at the bottom of the substrate first. After stacking the entire row of substrates and the column, the worker passes a steel bar through the sleeve in the middle of the entire row of substrates and connects it to the bottom base with a thread. At the same time, a nut is threaded to the top of the steel bar and tightened to fix the entire row of substrates. S4: After that, the workers wrapped the assembled modular matrix with geotextile and backfilled the earth. S5: During maintenance, workers first use ground-penetrating radar, acoustic wave detection and other methods to determine the location of the base plate to be replaced, and at the same time use a crane to connect to the top of the steel bar in the middle of the base plate; S6: Simultaneously, the crane pulls the steel bars along with the entire row of base plates out of the entire module row; S7: After extraction, loosen and remove the nut at the top of the reinforcing bar, and pull the damaged base plate out from the inside of the reinforcing bar. At the same time, reinstall the spare base plate back onto the outside of the reinforcing bar. S8: After that, the workers hoisted the repaired entire string of substrates back into the pit and pushed them horizontally back into place.

[0012] As can be seen from the above, the farmland irrigation system based on a rainwater harvesting module provided by the present invention has the following technical effects.

[0013] By incorporating an end sliding component, a tail sliding component, and a reinforcement structure in a cross shape into an existing farmland irrigation system based on rainwater harvesting modules, and in conjunction with a series mechanism mainly composed of steel bars, multiple functions can be achieved, specifically: Firstly, by utilizing the end sliding component, tail sliding component, and reinforcement components to support the inside of the column, a cross-shaped inner lining is set inside the traditional hollow column, transforming the column into a composite structure of "tube + cross core". This transforms the single hollow tube wall stress of the traditional column into a grid-like stress system, significantly improving compressive strength. Furthermore, the cross-shaped flanges can effectively prevent the column from buckling under lateral earth pressure, while dispersing the concentrated stress at the column root to the four flanges, thus avoiding root cracking.

[0014] Secondly, the end and tail sliding parts are both structural reinforcements and male connectors for vertical connection. They can connect the stacked substrates in the vertical direction in sequence by sliding under their own weight. This design integrates the connection structure, does not occupy extra space, and the connection force is directly applied to the load-bearing core, resulting in more reasonable force distribution and a more stable connection.

[0015] Thirdly, the steel bars that extend from the middle of the base plate sleeve can combine the distributed base plates and columns in a series. During maintenance, the faulty series can be pulled out in a coordinated manner, and the replacement can be completed without damaging the overall matrix, which greatly improves the convenience of traditional module maintenance.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The farmland irrigation system based on a rainwater harvesting module disclosed in this invention is mainly applied to the installation and maintenance of a rainwater harvesting module.

[0028] Reference Figures 1 to 9 A farmland irrigation system based on a rainwater harvesting module includes several uniformly distributed base plates 1. Several rows of uniformly distributed columns 2 are fixedly installed on the outer side of the base plates 1. Several vertically distributed base plates 1 are stacked sequentially through the columns 2. The interior of the columns 2 is provided with a reinforcing mechanism 3 to improve the structural strength of the entire harvesting module. The reinforcing mechanism 3 includes a reinforcing member 301 fixedly installed in the middle of each column 2. The upper and lower ends of each column 2 are respectively slidably installed with an end sliding member 302 and a tail sliding member 303. The reinforcing member 301, the end sliding member 302 and the tail sliding member 303 are all cross-shaped structures. The vertically stacked columns 2 and base plates 1 are connected to each other by the outwardly sliding end sliding member 302 and the tail sliding member 303. A series mechanism 4 is provided in the middle of the substrate 1 to facilitate workers to perform fixed-point maintenance. The series mechanism 4 includes a sleeve 401 provided in the middle of each substrate 1. Several sleeves 401 are stacked and symmetrically distributed in the vertical direction, and a steel bar 402 is installed through them. A base 403 is installed at the bottom of the steel bar 402. The base 403 is distributed at the bottom of the lower substrate 1. A nut 404 is installed at the top of the steel bar 402. The nut 404 presses against the top of the upper substrate 1.

[0029] In this embodiment: Workers excavate a foundation pit along the ground according to the set dimensions, and hoist the entire module to be assembled into the pit. At this time, workers stack multiple substrates 1 along the markings of the pit, relying on the columns 2, in the vertical and horizontal directions, and gently shake them. When stacking in the vertical direction, the substrates 1 will fit with adjacent substrates 1, and the columns 2 will fit with adjacent columns 2. At the same time, the end sliding parts 302 and tail sliding parts 303 located inside the columns 2 will slide vertically by their own weight and engage with the adjacent substrates 1 and columns 2. When stacking the lower substrates 1, a base 403 needs to be placed at the bottom of the substrate 1 first. After stacking the entire row of substrates 1 and columns 2, workers pass a steel bar 402 through the sleeve 401 in the middle of the row of substrates 1 and connect it to the bottom. The base 403 is threaded, and a nut 404 is threaded to the top of the rebar 402 and tightened to fix the entire row of base plates 1. After that, the workers wrap geotextile around the assembled module matrix and backfill the soil. During maintenance, the workers first use ground penetrating radar, sonic detection and other methods to determine the position of the base plate 1 to be replaced. At the same time, the crane is used to connect to the top of the rebar 402 in the middle of the base plate 1. The crane pulls the rebar 402 and the entire row of base plates 1 out of the entire module. After being pulled out, the nut 404 on the top of the rebar 402 is loosened and removed. The damaged base plate 1 is pulled out from the inside of the rebar 402. At the same time, the spare base plate 1 is reinstalled on the outside of the rebar 402. After that, the workers lift the repaired entire row of base plates 1 back into the foundation pit and push it in horizontally to reset it.

[0030] Specifically, each substrate 1 has a main dovetail groove 101 and a main dovetail piece 102 symmetrically arranged on its outer side. Two adjacent substrates 1 in the horizontal direction are connected by the main dovetail groove 101 and the main dovetail piece 102.

[0031] Reference Figures 6 to 8 In a preferred embodiment, the top and bottom of the column 2 are respectively provided with an end sliding groove 304 and a tail sliding groove 305. The end sliding member 302 is slidably distributed inside the end sliding groove 304, and the tail sliding member 303 is slidably distributed inside the tail sliding groove 305.

[0032] by Figure 8For example, when the worker inverts the middle substrate 1 and aligns the bottom post 2 of substrate 1 with the top post 2 of the lower substrate 1, the end sliding member 302 inside the post 2 will move down synchronously along the inside of the end sliding groove 304 due to its own weight. This causes the end sliding member 302 inside the middle post 2 to engage with the end sliding groove 304 inside the lower post 2, thereby fixing the lower substrate 1 and the middle substrate 1 together. The upper substrate 1 and the middle substrate 1 are engaged with each other by the tail sliding member 303 and the tail sliding groove 305. The specific engagement principle is the same as above.

[0033] The top of the end sliding groove 304 has a through opening 3041, and the adjacent end sliding members 302 in the vertical direction will slide and engage into the interior of the through opening 3041 to form a fixed position.

[0034] Reference Figure 3 and Figure 9 In a preferred embodiment, the bottom and top outer sides of the reinforcing bar 402 are respectively provided with threaded grooves 405, and are threadedly connected to the base 403 and the nut 404 through the threaded grooves 405.

[0035] When stacking the lower substrate 1, a base 403 needs to be placed at the bottom of the substrate 1 first. After stacking the entire row of substrates 1 and the column 2, the worker passes a steel bar 402 through the sleeve 401 in the middle of the row of substrates 1 and connects it to the base 403 at the bottom by rotating it and using the threaded groove 405. At the same time, a nut 404 is put on the top of the steel bar 402 and the nut 404 is tightened to the top of the steel bar 402 by using the threaded groove 405 to fix the entire row of substrates 1.

[0036] Specifically, a reinforcing plate 4031 is additionally provided on the outer side of the bottom of the base 403. The reinforcing plate 4031 is pressed against the outer side of the base plate 1, thereby improving the structural strength of the base 403.

[0037] Reference Figures 1 to 3 In a preferred embodiment, a side plate 5 is installed between two substrates 1 distributed in a vertical direction. The side plate 5 wraps around the outside of the entire collection module. Each side plate 5 has a secondary dovetail groove 501 and a secondary dovetail member 502 symmetrically arranged on its outer side. Two adjacent side plates 5 in the horizontal direction are connected by the secondary dovetail groove 501 and the secondary dovetail member 502. Dovetail combination grooves 503 are symmetrically opened between the upper and lower sides of each side plate 5 and the outer side of the substrate 1. A dovetail assembly member 504 is fixedly engaged inside the dovetail combination groove 503, and the side plate 5 and the substrate 1 are fixed by the dovetail assembly member 504.

[0038] After the workers have completed the installation of all the base plates 1 and the main body of the columns 2, they then install the individual side plates 5 one by one between the two base plates 1 located on the outer side, as shown in the attached figure. Figure 1 As shown, at this time, the dovetail combination groove 503 located at the upper and lower ends of the side plate 5 is aligned with the dovetail combination groove 503 on the outer side of the base plate 1. At the same time, the worker snaps the dovetail assembly 504 into the inside of the dovetail combination groove 503 to fix the side plate 5 and the base plate 1. After completing the installation of one side plate 5, the worker continues to splice the new side plate 5 to both sides of the installed side plate 5. The side plates 5 are connected to each other through the secondary dovetail groove 501 and the secondary dovetail component 502.

[0039] Working principle: During use, workers excavate a foundation pit along the ground according to the set dimensions and hoist the entire module to be assembled into the pit. Following the markings in the pit, workers stack multiple substrates 1 vertically and horizontally along the columns 2, gently wobbling them. Horizontally, they are connected by the main dovetail groove 101 and the main dovetail piece 102. Vertically, substrates 1 and columns 2 adhere to each other. Simultaneously, the end sliding piece 302 and tail sliding piece 303 inside the columns 2 slide vertically under their own weight and engage with adjacent substrates 1 and columns 2. When stacking the lower substrates 1, a base 403 is placed at the bottom of each substrate 1. After stacking the entire row of substrates 1 and columns 2, a steel bar 402 is passed through the sleeve 401 in the middle of the row of substrates 1 and connected to the bottom base 403 via a threaded groove 405 by rotation. A screw... The cap 404 is fitted onto the top of the reinforcing bar 402, and the nut 404 is tightened to the top of the reinforcing bar 402 using the threaded groove 405, thus fixing the entire row of base plates 1. After that, the workers wrap geotextile around the assembled module matrix and backfill the soil. During maintenance (when the module collapses or deforms, causing ground subsidence, etc.), the workers first determine the location of the base plate 1 to be replaced using various methods such as ground penetrating radar and acoustic detection. At the same time, a crane is used to connect to the top of the reinforcing bar 402 in the middle of the base plate 1. The crane pulls the reinforcing bar 402, along with the entire row of base plates 1, out of the entire module row. After extraction, the nut 404 at the top of the reinforcing bar 402 is loosened and removed, and the damaged base plate 1 is pulled out from the inside of the reinforcing bar 402. Meanwhile, the spare base plate 1 is reinstalled on the outside of the reinforcing bar 402. After that, the workers lift the repaired entire row of base plates 1 back into the pit and push it horizontally to reset. The rainwater harvesting module of this invention can greatly improve the efficiency of automated irrigation for crop planting.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
