[0024] Embodiment

[0025] For the cross-road drainage structure of high-standard farmland in the prior art, it is very inconvenient to fix it with the drainage ditch 2, which greatly reduces the efficiency of actual application. Secondly, its length needs to be spliced by multiple corresponding U-shaped drainage troughs, and the length cannot be adjusted, resulting in the inability to meet the drainage requirements of drainage ditches 2 of different lengths.

[0026] Therefore, please refer to Figures 1-5 , the present utility model provides a cross-road drainage structure for high-standard farmland, including: a cement roadbed 1 and a U-shaped drainage trough a3. The U-shaped drainage trough a3 is placed in the drainage ditch 2 provided in the middle of the cement roadbed 1. Two symmetrically arranged moving cavities are opened on the inner wall of the U-shaped drainage trough a3. The vertical cross-sections of the moving cavities are all U-shaped structures. U-shaped drainage troughs b31 are slidably arranged in the moving cavities. Sliding grooves 321 are opened on both sides of the top end of each moving cavity. Slide bars 32 with a convex-shaped vertical cross-section are slidably connected in the sliding grooves 321. Both sides of the bottom end of the U-shaped drainage trough b31 are fixedly connected to the top ends of the slide bars 32.

[0027] It also includes a length adjustment component and a support and fixation component 4. The length adjustment component is installed on the inner bottom wall of the U-shaped drainage trough a3 and is connected to the inner bottom walls of the two U-shaped drainage troughs b31. The length adjustment component can facilitate the adjustment of the applicable length of the drainage structure according to the length of the drainage ditch 2.

[0028] The support and fixation component 4 is installed on the length adjustment component and is connected to the U-shaped drainage trough a3. The support and fixation component 4 can facilitate the quick fixation and installation of the drainage structure in the drainage ditch 2.

[0029] On the top of the U-shaped drainage trough body a3 and the two U-shaped drainage trough bodies b31, a plurality of cover plates 5 are also placed. A plurality of drainage holes with the same size and diameter are opened on each cover plate 5. At the same time, the vertical cross-sections on both sides of the top of the U-shaped drainage trough body a3 and the vertical cross-sections on both sides of the top of the U-shaped drainage trough body b31 are both L-shaped structures, and the topmost parts on both sides of the top of the U-shaped drainage trough body a3 and the topmost parts on both sides of the top of the U-shaped drainage trough body b31 are flush with each other. In this way, after the length of the drainage structure is adjusted, a plurality of cover plates 5 can be placed;

[0030] After the drainage structure is applied in practice, since there is a gap between the bottom end of the U-shaped drainage trough body b31 and the inner bottom wall of the drainage ditch 2, it can be manually constructed and sealed at both ends of the drainage ditch 2 with the help of external concrete.

[0031] Furthermore, as Figures 1-4 shown, it is worth specifically stating that the length of the sliding strip 32 is equal to the length of the U-shaped drainage trough body b31, and both sides of the top of the U-shaped drainage trough body b31 are flush with both sides of the top of the U-shaped drainage trough body a3.

[0032] Furthermore, as Figures 1-5 shown, it is worth specifically stating that in order to enable the length of the drainage structure to be adjusted and adapted according to the lengths of different drainage ditches 2, a length adjustment component is provided, which includes a rotating handle 36 rotatably connected to the middle of the inner bottom wall of the U-shaped drainage trough body a3 through a bearing seat 37. The rotating handle 36 is fixedly connected to the outside of the rotating cylinder 35. Screw rods a34 are threadedly connected to both of the two symmetrically arranged threaded channels provided inside the rotating cylinder 35. The thread directions of the two screw rods a34 are opposite. One end of each of the two screw rods a34 away from each other is fixedly connected to the inner bottom wall of the U-shaped drainage trough body b31 through a connecting block 33. A hand-tightening screw 38 is threadedly penetrated through the bearing seat 37. The bottom end of the hand-tightening screw 38 after being tightened will abut against the outside of the rotating handle 36.

[0033] Among them, the setting of the hand-tightening screw 38 is to be able to lock and stop the rotating handle 36 after the adjustment is completed, effectively avoiding the accidental rotation of the rotating handle 36 resulting in a change in the length of the drainage structure.

[0034] Furthermore, as Figures 1-5As shown in the figure, it is worth specifically stating that in order to enable the drainage structure to be quickly fixed in the drainage ditch 2, a support and fixing component 4 is provided, which includes a screw b41 rotatably connected to the top end of a bearing block 37. A handwheel 42 is fixedly connected to the top end of the screw b41. A movable block 43 is threadedly connected to the middle of the screw b41. Push-pull rods 44 are hinged to both ends of the movable block 43. Vertical rods 45 with a square cross-sectional structure are hinged to the bottom ends of the push-pull rods 44. The opposite ends of the two vertical rods 45 movably penetrate to the outside of the U-shaped drainage trough a3 and are fixedly connected with supporting plates 46. The supporting surfaces of the supporting plates 46 are all abutted against the inner wall of the drainage ditch 2.

[0035] The supporting surface of the supporting plate 46 is uneven, which can increase the friction coefficient between it and the inner wall of the drainage ditch 2, so that the fixing stability is good.

[0036] In summary: When using this cross-road drainage structure for high-standard farmland, the drainage structure can be placed in the designated drainage ditch 2. By rotating the screw b41 through the handwheel 42, the movable block 43 moves downward. With the cooperation of the two push-pull rods 44, the two vertical rods 45 move away from each other, so that the two supporting plates 46 are both tightly abutted against the inner wall of the drainage ditch 2, which greatly improves the installation efficiency of the drainage structure. There is no need to use bolts for fixing. Secondly, according to the length of the drainage ditch 2, by loosening the hand-tightening screw 38, the rotating cylinder 35 can be rotated by rotating the handle 36. Since the thread directions of the two screws a34 are opposite, the two screws a34 move away from each other. With the setting of the connecting block 33, the two U-shaped drainage troughs b31 move away from each other in the U-shaped drainage trough a3, so as to expand its use length to meet the drainage ditch 2 with its applicable length, greatly improving the applicable range of the drainage structure. The setting of the hand-tightening screw effectively ensures that the subsequent rotating handle 36 will be locked and stopped, avoiding the change of the length of the adjusted drainage structure.
