Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy engineering technology, specifically to a prefabricated river channel for farmland. Background Technology

[0002] Farmland irrigation canals are waterways that connect irrigation water sources with irrigated land, transporting and distributing water drawn from the water source to various parts of the irrigation area. Within an irrigation area, canals are divided into five levels according to the size of the controlled area: main canals, branch canals, distribution canals, farm canals, and field canals.

[0003] For ease of use, for example, Chinese utility model patent CN215801480U discloses a novel prefabricated channel, including a fixed column. A conical head is fixedly connected to the bottom of the fixed column, and a connecting plate is fixedly connected to the top of the fixed column. A first fixed plate overlaps the top of the connecting plate, and the fixed plate is fixedly connected to the connecting plate by bolts. A channel bottom plate is fixedly connected to the front of the first fixed plate, and the side of the connecting plate near the channel bottom plate overlaps with the channel bottom plate. A threaded column is then inserted into a threaded groove through a threaded hole to fix the channel top plate. Multiple of these devices can be combined to assemble a complete channel, achieving the goal of easy channel assembly. This avoids the need for both rubble masonry and on-site installation of prefabricated trenches, avoiding the long construction period and high cost of rubble masonry, and avoiding the large volume caused by the monolithic structure of prefabricated trenches, making it more convenient to use.

[0004] However, some problems still exist. Although it avoids the large volume caused by the monolithic structure of most prefabricated ditches and makes them more convenient to install, directly inserting the side plates of the channel into the fixed groove to complete the installation of the side plates does not restrict the vertical movement of the side plates, resulting in poor stability. Therefore, a prefabricated farmland river channel is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prefabricated river channel for farmland, which has the advantage of high stability and solves the problem of poor stability caused by the lack of restrictions on the vertical movement of the channel side plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated river channel for farmland, comprising a base plate, mounting plates fixed on both the left and right sides of the base plate, mounting cones slidably connected inside the mounting plates, two positioning blocks fixed on the top of the base plate, and side plates fixed on the top of the positioning blocks;

[0007] The positioning block has two positioning components inside that are inserted into the side plate. The positioning components are used to position the side plate. The top of the left side plate is hinged to a top plate. The top plate has two fixing components inside that are inserted into the right side plate. The fixing components are used to fix the top plate.

[0008] The positioning assembly includes a positioning rod, a connecting block, a return spring, and a sliding block. The interior of the positioning block is slidably connected to the positioning rod. The positioning rod is inserted into a side plate. The outer surface of the positioning rod is rotatably connected to the connecting block. The connecting block and the positioning block are fixed together with the return spring. The bottom of the positioning rod is slidably connected to the sliding block fixed to the positioning block.

[0009] By adopting this technical solution and using a hinged connection, when opening the channel, one only needs to rotate the connecting rod to decouple it from the top plate, and then pull the connecting rod upwards to decouple it from the side plate, thus making the channel easy to open and making the whole system more practical.

[0010] Furthermore, the fixing assembly includes a connecting rod, a connecting rod, and a control block. The connecting rod is threadedly connected to the top plate, the bottom of the connecting rod is rotatably connected to the connecting rod inserted into the right side plate, and the top of the connecting rod is fixed to the control block.

[0011] By adopting this technical solution, when the connecting rod is inserted into the side plate, the movement of the side plate is arc-shaped, which allows the connecting rod to effectively restrict the movement of the side plate.

[0012] Furthermore, the connecting rod is an externally threaded rod, and the top plate has a threaded hole inside that is compatible with the connecting rod.

[0013] By adopting this technical solution and using threaded connections, it is impossible to push the connecting rod and the connecting rod to move when the side plate makes arc-shaped movements.

[0014] Furthermore, a limiting block is fixed inside the top plate, and positioning grooves that are adapted to the limiting block are opened on both the front and rear sides of the connecting rod.

[0015] By adopting this technical solution, the limiting block and positioning groove are designed to prevent the connecting rod from separating from the top plate, thus effectively preventing the loss of the connecting rod.

[0016] Furthermore, a sealing gasket is fixed inside the positioning block, and the top of the sealing gasket is tightly fitted to the side plate.

[0017] By adopting this technical solution and using the sealing gasket, the overall sealing performance can be effectively improved.

[0018] Furthermore, the top of the positioning rod is provided with an inclined surface, and a rubber pad is fixed to the bottom of the base plate.

[0019] By adopting this technical solution, the inclined surface is designed so that the positioning rod is squeezed when the side plate moves downward.

[0020] Furthermore, the bottom of the positioning rod is provided with a sliding groove that is slidably connected to the sliding block, and the front of the positioning rod is provided with a limiting groove that communicates with the sliding groove.

[0021] By adopting this technical solution, the sliding block makes the positioning rod move more stably, and when the sliding block moves into the limit groove, it can restrict the left and right movement of the positioning rod.

[0022] Furthermore, a stabilizing block is fixed to the front of the side plate, and a stabilizing groove adapted to the stabilizing block is provided on the back of the side plate.

[0023] By adopting this technical solution, the stabilizing blocks and grooves make the splicing of multiple side panels more stable.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. In this prefabricated farmland river channel, when the side plate is inserted into the positioning block, the positioning component is squeezed. When the side plate moves downward and contacts the sealing gasket and squeezes the sealing gasket, the positioning component will reset and insert into the side plate, thereby effectively restricting the vertical movement of the side plate, making the side plate more stable and effectively improving the overall practicality.

[0026] 2. This prefabricated farmland canal channel connects the top plate and the left side plate by hinge. When cleaning the canal, only the right-side fixing component needs to be rotated. The sealing gasket effectively improves the sealing at the connection between the side plate and the positioning block. The overall structure is simple and further improves the convenience of operation, making the whole system more practical. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1 to 2 In this embodiment, a prefabricated farmland waterway includes a base plate 1, a rubber pad 12 fixed to the bottom of the base plate 1, mounting plates 2 fixed to both the left and right sides of the base plate 1, mounting cones 3 slidably connected inside the mounting plates 2, two positioning blocks 4 fixed to the top of the base plate 1, a side plate 5 fixed to the top of the positioning blocks 4, a sealing gasket 13 fixed inside the positioning blocks 4, and the top of the sealing gasket 13 tightly fitting the side plate 5. The sealing gasket 13 effectively improves the overall sealing performance. A stabilizing block is fixed to the front of the side plate 5, and a stabilizing groove adapted to the stabilizing block is opened on the back of the side plate 5. The stabilizing block and the stabilizing groove make the splicing of multiple side plates 5 more stable.

[0033] In addition, the positioning block 4 has two positioning components 6 that are inserted into the side plate 5. The positioning components 6 are used to position the side plate 5. The top of the left side plate 5 is hinged to the top plate 7. The top plate 7 has two fixing components that are inserted into the right side plate 5. The fixing components are used to fix the top plate 7. The fixing components include a connecting rod 8, a connecting rod 9 and a control block 11. The connecting rod 8 is threaded to the top plate 7. The connecting rod 8 is an externally threaded rod. The top plate 7 has a threaded hole that matches the connecting rod 8. Through the threaded connection, the connecting rod 8 and the connecting rod 9 cannot be moved when the side plate 5 moves in an arc.

[0034] Furthermore, the bottom of the connecting rod 8 is rotatably connected to the connecting rod 9 inserted into the right side plate 5. The top plate 7 has a fixed limiting block 10 inside. The front and rear sides of the connecting rod 9 are provided with positioning grooves that are compatible with the limiting block 10. Through the setting of the limiting block 10 and the positioning groove, the connecting rod 9 will not separate from the top plate 7, thereby effectively preventing the loss of the connecting rod 9. The top of the connecting rod 8 is fixed to the control block 11. When the connecting rod 9 is inserted into the side plate 5, the movement of the side plate 5 is an arc movement, which allows the connecting rod 8 to effectively restrict the movement of the side plate 5.

[0035] In summary, the hinged connection allows for easy opening of the channel by simply rotating the connecting rod 8 to disconnect the threaded connection between the connecting rod 8 and the top plate 7, and then pulling the connecting rod 8 upwards to disconnect the connecting rod 9 from the side plate 5. This makes the channel easier to open and enhances its overall practicality.

[0036] Please see Figure 3 In this embodiment, the positioning component 6 includes a positioning rod 601, a connecting block 602, a return spring 603, and a sliding block 604. The interior of the positioning block 4 is slidably connected to the positioning rod 601. The top of the positioning rod 601 is provided with an inclined surface. The inclined surface is provided so that when the side plate 5 moves downward, it will squeeze the positioning rod 601. The positioning rod 601 is inserted into the side plate 5. The outer surface of the positioning rod 601 is rotatably connected to the connecting block 602. The connecting block 602 and the positioning block 4 are fixed with the return spring 603. The bottom of the positioning rod 601 is slidably connected to the sliding block 604 fixed to the positioning block 4. The bottom of the positioning rod 601 is provided with a sliding groove 605 that is slidably connected to the sliding block 604. The front of the positioning rod 601 is provided with a limiting groove 606 that communicates with the sliding groove 605. The sliding block 604 is provided so that the positioning rod 601 can move more stably. When the sliding block 604 moves into the interior of the limiting groove 606, it can restrict the movement of the positioning rod 601 in the left and right directions.

[0037] In summary, when the side plate 5 moves downward, it will press the positioning rod 601. When the side plate 5 moves to the bottom, the positioning rod 601 will be inserted into the side plate 5. The overall operation is convenient and the stability of the side plate 5 is improved, making the whole system more practical.

[0038] The working principle of the above embodiments is as follows:

[0039] After fixing the base plate 1 and mounting plate 2 to the ground using the mounting cone 3, the side plate 5 can be inserted into the positioning block 4. When the side plate 5 moves downward, it will contact the inclined surface on the positioning rod 601, thereby squeezing the positioning rod 601 and causing it to move outward from the positioning block 4. This causes the connecting block 602 to move together, pulling the return spring 603 to move. This allows the return spring 603 to accumulate elastic potential energy. When the side plate 5 moves downward and squeezes the sealing gasket 13, the hole on the side plate 5 will move to contact the positioning rod 601. At this time, under the push of the elastic potential energy of the return spring 603, the positioning rod 601 will contact the side plate 4. The side plate 5 is inserted to complete its positioning. When disassembly is required, the positioning rod 601 is pulled to disengage it from the side plate 5, causing the sliding block 604 to move into the limiting groove 606. Then, the positioning rod 601 can be rotated to move the sliding block 604 completely into the limiting groove 606. Since the limiting groove 606 is a vertical groove, the sliding block 604 cannot move left or right, thus preventing the positioning rod 601 from resetting. This makes it easier for both positioning components 6 to disengage from the side plate 5 simultaneously. The overall structure is simple and effectively improves the stability of the side plate 5, making the whole system more practical.
