DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses an irrigation and drainage channel structure for a farmland water conservancy project. Figure 1 The irrigation and drainage channel structure of the farmland water conservancy project includes a ditch body 1, in which a plurality of cleaning groups 2 are arranged at intervals along the length direction of the ditch body 1.

[0024] Reference Figure 1, a fixed column 13 is fixedly installed on the bottom wall of the ditch body 1, and the fixed column 13 corresponds to the cleaning group 2. Specifically, the cleaning group 2 includes a scraper 201, which is rotatably sleeved on the corresponding fixed column 13, the rotation axis of the scraper 201 is perpendicular to the bottom wall of the ditch body 1, the length direction of the scraper 201 is perpendicular to the rotation axis of the scraper 201, the scraper 201 abuts against the bottom wall of the ditch body 1, the fixed column 13 is located in the middle of the corresponding scraper 201, and the distances from both ends of the scraper 201 to its own rotation axis are greater than half of the width of the ditch body 1, that is, the distances from both ends of the scraper 201 to the fixed column 13 are greater than half of the width of the ditch body 1, so that one end of the scraper 201 is located at the front end of the ditch body 1 in the water flow direction, and the other end is located at the rear end of the ditch body 1 in the water flow direction; wherein, the front end and the rear end of the ditch body 1 are arranged in sequence along the drainage flow direction, and a driving component for driving the scraper 201 of the cleaning group 2 to swing back and forth is arranged in the ditch body 1.

[0025] When excess water in the farmland flows along the ditch body 1, the driving component drives the scraper 201 to swing back and forth, so that the scraper 201 scrapes the bottom wall of the ditch body 1, thereby stirring the sediment on the bottom wall of the ditch body 1, which not only makes it difficult for mud to settle, but also allows the already deposited mud to be washed away with the water flow; since the length of the scraper 201 is greater than the width of the ditch body 1, the scraper 201 of a group of cleaning groups 2 can scrape the ditch body 1 at intervals in the direction of water flow, and after the scraper 201 located at the front end of the water flow direction scrapes the sediment, the sediment will settle again after a distance, and the setting of the scraper 201 conforms to the law of sediment sedimentation, with a wide cleaning range, which helps to prevent the ditch body 1 from accumulating sediment and effectively ensure the drainage effect.

[0026] Reference Figure 1 and Figure 2 There are two scrapers 201 in each cleaning group 2. The two scrapers 201 in each cleaning group 2 are coaxially arranged, and a groove 14 is provided at the position where one of the scrapers 201 is sleeved with the fixed column 13, so that the two scrapers 201 can be rotatably sleeved with the fixed column 13, and the two scrapers 201 can be abutted against the inner wall of the groove body 1; wherein the driving assembly corresponds to the scrapers 201 one by one. There are two scrapers 201 in each cleaning group 2, which is convenient for driving the scrapers 201 to swing back and forth.

[0027] Reference Figure 2 and Figure 3In order to facilitate the rotation of the scraper 201 of the cleaning group 2, mounting rails 15 are installed on opposite sides of the ditch body 1 by bolts. The mounting rails 15 correspond to the driving components one by one. A mounting block 10 is provided on the mounting rail 15, and a support plate 16 is fixed on the mounting block 10. The driving component includes a rotating roller 3, a blade 4, a transmission member and a reset member. The rotating roller 3 is rotatably penetrated on the support plate 16 of the corresponding mounting block 10. The rotation axis of the rotating roller 3 is perpendicular to the length direction of the ditch body 1, and the rotation axis of the rotating roller 3 is arranged in the horizontal direction; a plurality of blades 4 are fixed along the circumference of the rotating roller 3, and the blade 4 is used to extend into the water flow in the ditch body 1. The transmission member is arranged on the corresponding mounting block 10, and the transmission member is used to drive the corresponding scraper 201 to rotate intermittently in the same direction when the rotating roller 3 rotates. The reset member is arranged on the fixed column 13, and the reset member is used to drive the scraper 201 to rotate for reset.

[0028] Reference Figure 2 and Figure 3 In order to facilitate the rotation of the rotating roller 3 and drive the scraper 201 to rotate intermittently in the same direction, the transmission member includes a first transmission piece 5, a transmission roller 6, a second transmission piece 7 and a connecting rope 8. The first transmission piece 5 is fixed on the rotating roller 3, and the first transmission piece 5 is located on the side of the blade 4 close to the inner wall of the groove body 1. In the embodiment of the present application, two first transmission pieces 5 are arranged along the circumference of the rotating roller 3, and the central angle of the two first transmission pieces 5 is less than 90 degrees; the transmission roller 6 is rotatably penetrated on the support plate 16 of the corresponding mounting block 10, and the rotation axis of the transmission roller 6 is parallel to the rotation axis of the rotating roller 3. A plurality of second transmission pieces 7 are fixedly arranged along the circumference of the transmission roller 6, and the first transmission piece 5 is used to abut against the second transmission piece 7 to bring The dynamic transmission roller 6 rotates, and a reel 17 is coaxially fixed on the transmission roller 6. The reel 17 is located on the side of the corresponding second transmission plate 7 away from the inner wall of the groove body 1. The connecting rope 8 is wound around the reel 17 of the transmission roller 6, and one end of the connecting rope 8 away from the reel 17 is fixed to the side of the corresponding scraper 201 located at the front end of the water flow direction of the groove body 1, so as to adjust the rotation of the scraper 201; when the first transmission plate 5 drives the second transmission plate 7 and the transmission roller 6 to rotate, the transmission roller 6 reels the connecting rope 8; when the first transmission plate 5 is disengaged from the second transmission plate 7, the end of the scraper 201 connected to the connecting rope 8 is located at a side wall of the groove body 1 away from the corresponding transmission roller 6, so that the corresponding two connecting ropes 8 of the same cleaning group 2 are cross-arranged.

[0029] Reference Figure 2 and Figure 4 In order to facilitate the rotation and reset of the scraper 201, the reset member includes a coil spring 9, which corresponds to the scraper 201 one by one. The coil spring 9 is sleeved on the fixed column 13, and one end of the coil spring 9 is fixed on the fixed column 13, and the other end is fixed on the corresponding inner wall of the scraper 201. When the coil spring 9 is in a natural state, the end of the scraper 201 connected to the connecting rope 8 is located at a side wall of the groove body 1 away from the corresponding transmission roller 6.

[0030] When the ditch body 1 is drained, the blades 4 extend into the water flow, and the water flow impacts the blades 4, driving the blades 4 to drive the rotating roller 3 to rotate. The rotating roller 3 drives the transmission roller 6 to rotate by abutting the second transmission plate 7 through the first transmission plate 5. The transmission roller 6 drives the winding connecting rope 8 by driving the reel 17 to rotate. The connecting rope 8 pulls the connection position of the corresponding scraper 201 to rotate in the direction close to the corresponding rotating roller 3, so that the two scrapers 201 approach each other, the coil spring 9 is deformed, and the two scrapers 201 scrape the bottom wall of the ditch body 1, which helps to reduce soil deposition. Since there are only two first transmission plates 5, when the first transmission plate 5 is separated from the second transmission plate 7, the deformed coil spring 9 drives the two scrapers 201 to rotate in the opposite direction to reset. At the same time, under the impact of the water flow, the two scrapers 201 move away from each other, and the reciprocating movement is realized to realize the intermittent rotation of the scraper 201.

[0031] Reference Figure 2 and Figure 3 The length direction of the mounting rail 15 is parallel to the inclination direction of the corresponding side wall of the ditch body 1, the mounting block 10 is slidably arranged on the mounting rail 15, the sliding direction of the mounting block 10 is parallel to the length direction of the mounting rail 15, the mounting block 10 is provided with an adjusting member for making the mounting block 10 rise and fall with the rise and fall of the water level in the ditch body 1, and the transmission roller 6 is provided with an elastic member for driving the transmission roller 6 to rotate and reel the connecting rope 8, and the torsion of the elastic member is less than the corresponding coil spring 9 (refer to Figure 4 ) of torque.

[0032] Reference Figure 2 and Figure 3 In order to facilitate the installation block 10 to rise and fall with the rise and fall of the water level in the ditch body 1, the adjusting member includes a floating block 11, and the floating block 11 is fixedly arranged on the bottom wall of the installation block 10. The distance from the side of the blade 4 away from the rotating roller 3 to the center of the rotating roller 3 is greater than the distance from the bottom wall of the floating block 11 to the center of the rotating roller 3, so as to ensure that the blade 4 can extend into the water.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the rotation of the transmission roller 6 to reel in the connecting rope 8, the elastic member includes a torsion spring 12 sleeved on the transmission roller 6, one end of the torsion spring 12 is fixed on the support plate 16, and the other end is fixed on the corresponding transmission roller 6.

[0034] When the water level in the ditch body 1 rises and falls, under the buoyancy of the floating block 11 and the gravity of the mounting block 10, the floating block 11 will drive the mounting block 10 to rise and fall with the water level to ensure that the blade 4 can always extend into the water, and the blade 4 drives the rotating roller 3 to rotate through the impact of the water flow; when the mounting block 10 moves toward the direction close to the bottom wall of the ditch body 1, the distance between the reel 17 and the corresponding scraper 201 is shortened, and the torsion spring 12 drives the transmission roller 6 to rotate to reel in the connecting rope 8, so that the connecting rope 8 remains tensioned. , so that when the first transmission plate 5 drives the second transmission plate 7 to rotate, the reel 17 can reel in the connecting rope 8 and pull the scraper blade 201 to rotate; when the mounting block 10 moves in a direction away from the bottom wall of the groove body 1, the distance between the reel 17 and the corresponding scraper blade 201 is extended. Since the torsion force of the torsion spring 12 is less than the torsion force of the coil spring 9, the connecting rope 8 will not pull the scraper blade 201 to move, but will pull the transmission roller 6 to rotate so that the reel 17 can further unwind the connecting rope 8, and the connecting rope 8 is still in a tensioned state.

[0035] The implementation principle of the embodiment of the present application is as follows: when the drainage flows along the ditch body 1, under the buoyancy of the floating block 11 and the gravity of the mounting block 10, the floating block 11 will drive the mounting block 10 to rise and fall with the water level, and at the same time, under the action of the torsion spring 12, the connecting rope 8 can be kept in a tensioned state at all times; at this time, the blade 4 located at the lower side of the rotating roller 3 extends into the water, and the surface of the blade 4 meets the water flow, and then the water flow impacts the blade 4, driving the blade 4 to drive the rotating roller 3 to rotate, and the rotating roller 3 drives the transmission roller 6 to rotate by abutting the second transmission plate 7 through the first transmission sheet 5, and the transmission roller 6 drives the winding drum 17 to rotate and reel in the connecting rope 8, The connecting rope 8 pulls the connecting position of the corresponding scraper 201 to rotate toward the direction close to the corresponding rotating roller 3, so that the two scrapers 201 are close to each other. The two scrapers 201 scrape the bottom wall of the ditch body 1, which helps to reduce soil deposition; when the first transmission plate 5 is separated from the second transmission plate 7, the deformed coil spring 9 drives the two scrapers 201 to rotate in the opposite direction for reset, and pulls the connecting rope 8 to rotate the drum 17. At the same time, under the impact of the water flow, it is further convenient for the two scrapers 201 to move away from each other; in this reciprocating manner, the scraper 201 can swing intermittently, which helps to prevent the ditch body 1 from accumulating sediments and effectively ensure the drainage effect.

[0036] The present application also discloses a construction method of the irrigation and drainage channel structure of the above-mentioned farmland water conservancy project, comprising the following steps: Step 1, trench excavation: digging a trench on the soil surface; Step 2, laying the cushion layer: laying the base layer at the bottom of the trench; Step 3, support box installation: place the support box on top of the base layer in the trench; Step 4, installation of the trench body 1: fixing the trench body 1 on the supporting box; Step 5, installation of the cleaning group 2 and the driving assembly: a fixed column 13 with two scrapers 201 is installed and rotated at intervals along the length direction of the ditch body 1, and the scraper 201 is abutted against the bottom wall of the ditch body 1. Then, a mounting rail 15 is fixedly connected to the side wall of the ditch body 1 by bolts, and the mounting rail 15 is aligned with the front end of the corresponding scraper 201 close to the water flow direction of the ditch body 1 to install the driving assembly corresponding to the scraper 201.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
