Description

Technical Field

[0001] This application relates to the technical field of irrigation channels, and in particular to a structure for an anti-seepage irrigation channel for farmland and its construction method. Background Technology

[0002] Common methods of farmland irrigation include flood irrigation, canal irrigation, and ditch irrigation. Canal irrigation involves diverting water from a water source into an irrigation canal, and then distributing the water to the farmland through the canal. This method allows for control of water volume and irrigation time as needed and is suitable for different types of crops.

[0003] Irrigation channels typically have a large flow of water when crops need irrigation. When irrigation is not being carried out, there is only a small amount of water in the channels, which makes it easy for moss to grow on the inner walls of the channels. Moss has a strong ability to reproduce and grow, and a large amount of moss can affect the water conveyance function of the irrigation channels and also affect water quality. Summary of the Invention

[0004] To address the problem of moss growth on the inner walls of irrigation channels, this application provides a structure for an anti-seepage irrigation channel for farmland and its construction method.

[0005] Firstly, the farmland irrigation seepage prevention channel structure provided in this application adopts the following technical solution: A farmland irrigation seepage prevention channel structure includes a channel body and a movable frame. The movable frame moves along the length of the channel body. The movable frame includes a movable plate installed on the top surface of the channel body. Two fixed plates are fixed to the bottom surface of the movable plate. A scraper block is vertically slidably installed on the fixed plates. The scraper block can fit against the inner wall of the channel body. A scraper is slidably installed on the movable frame along the width direction of the channel body. A scraper block is fixed to the bottom surface of the scraper. The scraper block can fit against the inner bottom surface of the channel body. The movable frame is provided with a driving component for driving the scraper block to reciprocate vertically and a pushing component for driving the scraper block to reciprocate along the width direction of the channel body.

[0006] By adopting the above technical solution, scraping block one adheres to the inner wall of the channel body and moves back and forth vertically to scrape the moss on the inner side wall of the channel body. Scraping block two adheres to the inner bottom surface of the channel body and moves back and forth along the width direction of the channel body to scrape the moss on the inner bottom surface of the channel body. The moving frame moves along the length direction of the channel body to scrape the moss inside the channel body with scraping block one and scraping block two, thereby reducing the impact of moss on the water quality in the irrigation channel.

[0007] Preferably, the bottom surface of the movable plate is provided with a movable groove, and the scraper slides and cooperates with the movable plate along the width direction of the channel body through the movable groove. The pushing component includes a reciprocating screw rotatably installed in the movable groove, and the scraper is sleeved on the outer periphery of the reciprocating screw. The scraper and the reciprocating screw are threadedly driven together.

[0008] By adopting the above technical solution, the reciprocating screw is rotated, which drives the scraper to move back and forth along the width direction of the channel body, thereby driving the scraping block two to move along the width direction of the channel body, so as to facilitate the scraping block two to scrape the moss on the bottom surface of the channel body.

[0009] Preferably, the fixing plate has a dovetail groove on the side away from the scraper, and a dovetail block is mounted on the fixing plate by sliding vertically through the dovetail groove. The dovetail block is fixedly connected to the scraper block.

[0010] By adopting the above technical solution, the dovetail block moves vertically within the dovetail groove, and the dovetail block drives the scraping block to move back and forth vertically, so as to facilitate the scraping block to scrape the moss on the inner wall of the channel body.

[0011] Preferably, the driving assembly includes a first connecting rope and two second connecting ropes. The top of the fixing plate near the scraper has a first connecting hole that communicates with the dovetail groove. The top of the scraper has a second connecting hole. The first connecting rope passes through the first and second connecting holes. Both ends of the first connecting rope are fixedly connected to the top surface of the dovetail block. The bottom of the fixing plate near the scraper block has a third connecting hole that communicates with the dovetail groove. The second connecting rope passes through the third connecting hole. One end of the second connecting rope is fixedly connected to the scraper block, and the other end of the second connecting rope is fixedly connected to the bottom surface of the dovetail block.

[0012] By adopting the above technical solution, when scraper block 2 moves along the width direction of the channel body under the action of the reciprocating screw, scraper block 2 is fixedly connected to two dovetail blocks through connecting rope 1 and two connecting ropes 2. During the movement of scraper block 2, it drives the two dovetail blocks to move vertically, and the dovetail blocks drive scraper block 1 to move synchronously, thereby making scraper block 1 move vertically reciprocating.

[0013] Preferably, the bottom surface of the movable plate is fixed with two limiting blocks, which are respectively located on both sides of the channel body. A limiting groove is opened on the outer side of the channel body, and the limiting groove is arranged along the length direction of the channel body. A clearance groove is opened on the side of the limiting block. A vertically arranged rotating rod is rotatably installed in the clearance groove. A moving wheel is sleeved and fixed on the outer peripheral surface of the rotating rod. The outer peripheral surface of the moving wheel is in contact with the inner wall of the limiting groove. A rotating component for driving the rotating rod to rotate is provided on the movable frame.

[0014] By adopting the above technical solution, the movable wheel is inserted into the limiting groove, so that the movable plate is connected and cooperated with the channel body. The movable wheel moves along the length direction of the channel body through the limiting groove. The rotating component drives the rotating rod to rotate, and the rotating rod drives the movable wheel to rotate. The movable wheel moves in the limiting groove, thereby driving the movable frame to move along the length direction of the channel body.

[0015] Preferably, the rotating assembly includes a worm gear sleeved and fixed to the outer periphery of the rotating rod, and worms are fixed to both ends of the reciprocating screw. The worm gear and the worm mesh with each other. A drive motor is mounted on the moving plate, and the output end of the drive motor is fixedly connected to the end of one of the worms.

[0016] By adopting the above technical solution, the drive motor is started, which drives the worm and the reciprocating screw to rotate. The worm drives the worm wheel to rotate, the worm wheel drives the rotating rod to rotate, and in turn drives the moving wheel to rotate.

[0017] Preferably, two connecting plates are fixed to the side of the movable plate, and a vertically arranged filter plate is installed between the two connecting plates. A connecting rod is rotatably installed at the bottom of the filter plate, and a carrying filter plate is sleeved on the outer periphery of the connecting rod. The carrying filter plate is located on the side of the filter plate closer to the movable plate. A torsion spring is sleeved on the outer periphery of the connecting rod. One end of the torsion spring is fixedly connected to the filter plate, and the other end of the torsion spring is fixedly connected to the carrying filter plate.

[0018] By adopting the above technical solution, the filter plate is set vertically, and the supporting filter plate is attached to the inner bottom surface of the channel body under the elastic force of the torsion spring. Scraping block one and scraping block two scrape off the moss on the inner wall of the channel body, and the filter plate and the supporting filter plate collect the moss so that the staff can handle the moss.

[0019] Preferably, the connecting plate has a snap-fit ​​groove on its side near the filter plate, and a snap-fit ​​block is slidably mounted on the connecting plate along the width direction of the channel body through the snap-fit ​​groove. The filter plate has a positioning groove on its side for inserting the snap-fit ​​block. The snap-fit ​​block has a connecting groove on its side, and a connecting block is fixed to the inner wall of the snap-fit ​​groove. The connecting block passes through the connecting groove, and a connecting spring is fixed to the side of the connecting block near the filter plate. The end of the connecting spring away from the connecting block is fixedly connected to the side of the connecting groove near the filter plate.

[0020] By adopting the above technical solution, the filter plate is placed between two connecting plates, and the snap-fit ​​groove is aligned with the positioning groove. The snap-fit ​​block is inserted into the positioning groove under the elastic force of the snap-fit ​​spring, thereby snapping and fixing the filter plate and the connecting plate so that the filter plate can filter moss. When the filter plate needs to be disassembled, the snap-fit ​​block is moved away from the filter plate so that the filter plate and the connecting plate can be separated.

[0021] Preferably, a support rod is hinged to the side of the support filter plate away from the filter plate, and a support groove for inserting the support rod is opened on the side of the moving plate near the filter plate. A magnetic block one is fixed to the top of the support rod, and a magnetic block two for attracting the magnetic block one is embedded and fixed in the inner wall of the support groove.

[0022] By adopting the above technical solution, the support rod is inserted into the support groove, and the first magnetic block and the second magnetic block attract each other, so that the support rod is not easy to detach from the support groove. After the filter plate is disassembled, the support rod is moved upward, and the support rod drives the support filter plate to rotate upward, so that the moss accumulates between the filter plate and the support filter plate, making it easier for the staff to clean the moss.

[0023] Secondly, the construction method for a farmland irrigation seepage prevention channel structure provided in this application adopts the following technical solution, including the following steps: Place the movable plate on the top surface of the channel body, then insert the movable wheels into the limiting grooves. Start the drive motor, which drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating rod to rotate, which in turn drives the movable wheels to rotate.

Scraping block two adheres to the inner bottom surface of the channel body and moves back and forth along the width of the channel body to scrape the moss on the inner bottom surface of the channel body. The moving frame moves along the length of the channel body to scrape the moss inside the channel body with scraping block one and scraping block two, thereby reducing the impact of moss on the water quality in the irrigation channel. 2. Rotate the reciprocating screw, which drives the scraper to move back and forth along the width of the channel body, thereby driving the scraping block two to move along the width of the channel body, so as to scrape the moss on the bottom surface of the channel body. 3. When scraper block 2 moves along the width of the channel body under the action of the reciprocating screw, scraper block 2 is fixedly connected to two dovetail blocks through connecting rope 1 and two connecting ropes 2.
