Description

Technical Field

[0001] The utility model relates to the technical field of farmland construction, in particular to a drainage ditch cover plate. Background Art

[0002] Farmland construction refers to the activities of carrying out infrastructure construction such as farmland water conservancy and farmland roads, as well as cultivated land reclamation, soil improvement and fertilization, and farmland ecological protection and restoration by adopting technologies and agronomic measures such as engineering, biology, and chemistry in order to stabilize the cultivated land area, improve the cultivated land quality, and maintain the farmland ecological safety. During the farmland construction process, drainage ditches for irrigation and drainage need to be set in the farmland. In order to ensure the passage of agricultural machinery and the normal operation of the drainage and irrigation system, people usually set drainage ditch cover plates on the ditches.

[0003] The patent with the publication number CN215210297U discloses "an installation structure of a ditch cover plate, which is applied to a drainage ditch, including a cover plate body placed on the upper surface of the drainage ditch. The cover plate body is convexly provided with a positioning member, and a positioning groove for inserting the positioning member is opened on the upper end surface of the drainage ditch. When an agricultural machine needs to cross a drainage ditch from one field to another field, the staff places the cover plate body on the drainage ditch and makes the positioning member inserted into the positioning groove, so as to effectively limit the freedom degree of the cover plate body in horizontal sliding, thereby reducing the possibility of the ditch cover plate moving".

[0004] In view of the above related technologies, the inventor believes that the middle part of the bottom surface of the cover plate is suspended, and when the agricultural machine passes through the ditch, it is completely supported by both ends of the cover plate. The load-bearing effect is average, and it cannot support the passage of larger and heavier agricultural machines. When larger and heavier agricultural machines pass, they need to bypass this section of the ditch, which is rather inconvenient. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the utility model provides a drainage ditch cover plate, and the specific technical solutions are as follows:

[0006] A drainage ditch cover plate includes a drainage ditch, a plurality of cover plate bodies installed on the top of the drainage ditch, and a support mechanism arranged in the drainage ditch for supporting the bottom of the cover plate bodies. The support mechanism includes a support plate fixedly arranged in the middle of the bottom surface of the cover plate body, and a support rod fixedly arranged on the bottom surface of the support plate and cooperatively abutted against the bottom of the inner wall of the drainage ditch. A circular tube is rotatably arranged on the outer wall of the support rod, and a water wheel for driving the circular tube to rotate by the impact of water flow to spin the garbage around the support rod is fixedly arranged on the outer wall of the bottom end of the circular tube. A protective cover for protecting the water wheel is fixedly arranged on the outer wall of the circular tube.

[0007] By adopting the above technical solution, through the arrangement of the support rod and the support plate, the middle part of the bottom surface of the cover plate body can be supported, so as to improve the bearing capacity of the cover plate, allowing larger and heavier agricultural machinery to pass through. And the water wheel will rotate under the impact of the water flow in the drainage ditch, thereby driving the round pipe and the protective cover to rotate and separating the garbage in the water around the support rod, so that the garbage is not easy to accumulate at the support rod, achieving the effect of anti-blocking. The protective cover can protect the water wheel and prevent the garbage in the water from winding around the water wheel and affecting the rotation.

[0008] Optionally, buckle grooves are respectively opened on both sides of the top of the drainage ditch, and both ends of the cover plate body are respectively buckled in two matching buckle grooves. A plurality of jacks are opened in the buckle grooves of the drainage ditch, and insertion rods are fixedly arranged at the bottoms of both ends of the cover plate body and are adapted to be inserted into the jacks. A clamping groove is opened in the jack of the drainage ditch, and a plurality of rubber clamping blocks are fixedly arranged on the outer wall of the insertion rod and are adapted to be clamped in the clamping groove.

[0009] By adopting the above technical solution, through the connection of components such as the insertion rod and the rubber clamping block, the cover plate body on the drainage ditch can be fixed, so that the cover plate body is not easy to loosen under the impact of the water flow after the water level in the drainage ditch rises, improving the stability of the cover plate body.

[0010] Optionally, a push rod is fixedly arranged on the outer wall of the bottom end of the round pipe and is adapted to abut against the bottom of the inner wall of the drainage ditch.

[0011] By adopting the above technical solution, after the round pipe rotates, it will drive the push rod to rotate, so as to push the sedimented foreign matters at the bottom of the drainage ditch and partially clean the bottom of the drainage ditch.

[0012] Optionally, a plurality of drainage holes for drainage are opened between the cover plate body and the support plate. A filter screen adapted to the drainage holes of the cover plate body and the support plate is slidably arranged in the drainage holes. A spring is fixedly arranged at the bottom of the filter screen, and a connecting frame is fixedly arranged at the bottom end of the spring. The connecting frame is fixedly connected to the bottom of the support plate.

[0013] By adopting the above technical solution, the drainage holes cooperate with the filter screen to drain water and can also filter and block garbage such as leaves. After the user presses down the filter screen with his hand, he can pass through the drainage holes and lift and carry the cover plate from the bottom of the cover plate body, which is convenient for operation.

[0014] In summary, the present utility model has at least the following beneficial effects:

[0015] 1. Through the settings of the support rod and the support plate, the middle part of the bottom surface of the cover plate body can be supported, thereby improving the bearing capacity of the cover plate, allowing larger and heavier agricultural machinery to pass through. Moreover, the water wheel will rotate under the impact of the water flow in the drainage ditch, driving the round pipe and the protective cover to rotate and spin away the garbage in the water around the support rod, preventing the garbage from accumulating at the support rod and achieving the effect of anti-blocking. The protective cover can protect the water wheel, preventing the garbage in the water from winding around the water wheel and affecting the rotation, which is convenient and practical.

[0016] 2. Through the connection of components such as the insertion rod and the rubber clamping block, the cover plate body on the drainage ditch can be fixed, making the cover plate body not easy to loosen under the impact of the water flow after the water level in the drainage ditch rises, improving the stability of the cover plate body. The drainage hole is matched with the filter net, which can not only drain water but also filter and block garbage such as leaves. After the user presses down the filter net with his hand, he can pass through the drainage hole and lift and carry the cover plate from the bottom of the cover plate body, which is convenient for operation.

Detailed Description of the Embodiment

[0022] The following further describes the present utility model in detail with reference to the Figures 1-4 drawings.

[0023] The embodiment of the present utility model discloses a cover plate for a drainage and irrigation ditch, referring to Figures 1-2 , which includes a drainage ditch 1, a plurality of cover plate bodies 2 and a support mechanism. The drainage ditch 1 is a ditch for irrigation and drainage in farmland construction, and the cover plate body 2 is an existing cover plate for a drainage and irrigation ditch. Its main function is to cover the ditch to facilitate the passage of agricultural machinery and ensure the normal operation of the drainage and irrigation system.

[0024] Referring to Figures 1-3, buckles 11 are provided on both sides of the top of the drainage ditch 1. Both ends of the cover body 2 are respectively buckled in two matching buckles 11. The drainage ditch 1 can support and limit the cover body 2 through the buckles 11, and the top surfaces of the drainage ditch 1 and the cover body 2 are flush. The drainage ditch 1 can carry and support the cover body 2 through both ends.

[0025] Refer to Figures 1-3 , a number of jacks 12 are provided in the buckles 11 of the drainage ditch 1. Insertion rods 21 that are fixedly provided at the bottoms of both ends of the cover body 2 and are adapted to be inserted into the jacks 12. After the insertion rods 21 are inserted into the corresponding jacks 12, the drainage ditch 1 and the cover body 2 can be further connected, so that the cover body 2 will not slide on the drainage ditch 1 under the impact of water flow.

[0026] Refer to Figures 2-3 , a clamping groove 13 is provided in the jack 12 of the drainage ditch 1. A number of rubber clamping blocks 22 that are fixedly provided on the outer wall of the insertion rod 21 and are adapted to be clamped in the clamping groove 13 are provided. The rubber clamping blocks 22 can be spherical in shape. Among them, the rubber clamping blocks 22 can be inserted into the clamping groove 13 as the insertion rod 21 moves downward, so as to connect and fix between the drainage ditch 1 and the cover body 2, so that the cover body 2 is not easily loosened under the impact of water flow after the water level in the drainage ditch 1 rises, and the stability of the cover body 2 is improved.

[0027] After the user pulls the cover body 2 upward with great force, one end of the rubber clamping block 22 will deform and contract into the insertion rod 21, so that the rubber clamping block 22 will disengage from the clamping groove 13. With continuous upward pulling, the insertion rod 21 will disengage from the jack 12, and the cover body 2 will disengage from the buckle 11, so as to lift and carry the cover body 2.

[0028] Refer to Figures 2-3 , the support mechanism includes a support plate 3 fixedly provided in the middle of the bottom surface of the cover body 2, and a support rod 31 fixedly provided on the bottom surface of the support plate 3 and adapted to abut against the bottom of the inner wall of the drainage ditch 1. The support rod 31 can connect the support plate 3 and the drainage ditch 1. The support rod 31 and the support plate 3 can support the cover body 2 from the middle of the bottom surface of the cover body 2. Cooperating with the support of the drainage ditch 1 at both ends of the cover body 2 can improve the bearing capacity of the cover body 2, so that larger and heavier agricultural machinery can pass through the cover body 2.

[0029] Refer to Figure 2 And Figure 4, a circular tube 32 is rotatably provided on the outer wall of the support rod 31. A water wheel 33 is fixedly provided on the outer wall of the bottom end of the circular tube 32, which is used to drive the circular tube 32 to rotate by the impact of water flow, so as to spin off the garbage around the support rod 31. The support rod 31 can support and limit the circular tube 32. The support rod 31 is located inside the circular tube 32 that covers it. The water wheel 33 will rotate under the impact of the water flow in the drainage ditch 1, thereby driving the circular tube 32 to rotate and spin off the garbage such as leaves in the water around the support rod 31, making it difficult for the garbage to accumulate at the support rod 31 and achieving the effect of preventing blockage.

[0030] Refer to Figure 2 and Figure 4 , a protective cover 34 is fixedly provided on the outer wall of the circular tube 32 for protecting the water wheel 33. The water wheel 33 is located inside the protective cover 34. The holes of the protective cover 34 are relatively large, which is convenient for the water flow to pass through the protective cover 34 to impact and push the water wheel 33. Moreover, the protective cover 34 can block the garbage such as leaves through its own holes, thereby protecting the water wheel 33 and preventing the garbage in the water from winding around the water wheel 33 and affecting the rotation. And the protective cover 34 will also rotate with the circular tube 32 to spin off the garbage such as leaves in the water around the support rod 31.

[0031] Refer to Figure 2 , a push rod 35 is fixedly provided on the outer wall of the bottom end of the circular tube 32, which is fitted and abutted against the bottom of the inner wall of the drainage ditch 1. After the circular tube 32 rotates, it will drive the push rod 35 to rotate, so as to push the sedimented foreign matters at the bottom of the drainage ditch 1 and partially clean the bottom of the drainage ditch 1.

[0032] Refer to Figures 1-2 , a number of drainage holes 4 for draining water are provided between the cover plate body 2 and the support plate 3. The drainage holes 4 can drain the rainwater on the cover plate body 2 and the top of the drainage ditch 1, so that the cover plate body 2 and the top of the drainage ditch 1 are not easily waterlogged.

[0033] Refer to Figures 1-2 , a filter screen 41 that is adapted is slidably provided in the drainage hole 4 of the cover plate body 2 and the support plate 3. The filter screen 41 can block the garbage and prevent the garbage from entering the drainage ditch 1 through the drainage hole 4 and polluting the water source.

[0034] Refer to Figure 2 , a spring 42 is fixedly provided at the bottom of the filter screen 41. The bottom end of the spring 42 is fixedly provided with a connecting frame 43. The connecting frame 43 is fixedly connected to the bottom of the support plate 3. The connecting frame 43 can connect the spring 42 and the support plate 3, and the connecting frame 43 supports the spring 42. The spring 42 can elastically support the filter screen 41. After the user presses the filter screen 41 downward with his hand, the filter screen 41 can be pressed below the support plate 3, and then the user can lift and carry the cover plate body 2 by passing his hand through the drainage hole 4 from the bottom of the cover plate body 2 and the support plate 3.

[0035] The implementation principle of a kind of over-drainage ditch cover plate in the embodiment of the utility model is as follows:

[0036] During installation, both ends of the cover plate body 2 can be placed into the corresponding buckles 11 on both sides of the drainage ditch 1, and the inserting rods 21 can enter the corresponding inserting holes 12. Then, the cover plate body 2 is pressed downwards. The rubber clamping blocks 22 can be inserted into the clamping grooves 13 along with the downward movement of the inserting rods 21, so as to connect and fix between the drainage ditch 1 and the cover plate body 2, making the cover plate body 2 not easy to loosen under the impact of water flow after the water level in the drainage ditch 1 rises, and improving the stability of the cover plate body 2;

[0037] During use, the supporting rod 31 and the supporting plate 3 can support the cover plate body 2 from the middle of the bottom surface of the cover plate body 2. Cooperating with the support of the drainage ditch 1 on both ends of the cover plate body 2, the bearing capacity of the cover plate body 2 can be improved, so that agricultural machinery with larger volume and heavier weight can pass through the cover plate body 2;

[0038] The water wheel 33 will rotate under the impact of water flow in the drainage ditch 1, thereby driving the round pipe 32 and the protective cover 34 to rotate to spin away the garbage such as leaves in the water around the supporting rod 31, so that the garbage is not easy to accumulate at the supporting rod 31, playing an anti-blocking effect;

[0039] When it is necessary to move the cover plate body 2 to other positions of the drainage ditch 1, the user can press down the filter net 41 with his hand to press the filter net 41 below the supporting plate 3. Then, the user can pass his hand through the drainage hole 4 to pull up the cover plate body 2 strongly from the bottom of the cover plate body 2 and the supporting plate 3, so that one end of the rubber clamping block 22 deforms and contracts into the inserting rod 21. At this time, the rubber clamping block 22 will disengage from the clamping groove 13. With continuous pulling up, the inserting rod 21 will disengage from the inserting hole 12, and the cover plate body 2 will disengage from the buckle 11, so as to lift and carry the cover plate body 2 as a whole.

[0040] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
