Description

Technical Field

[0001] The utility model relates to the technical field of drainage ditches, in particular to a double-layer structure drainage ditch used for land reclamation. Background Art

[0002] Farmland planning and management is an important part of land reclamation. The most commonly used management method in farmland planning and management is to divide the land by building drainage ditches and allocate water resources in time and space, so as to improve the relationship between water, fertilizer, air and heat in the soil to facilitate crop growth. Drainage ditches with different structures can have different functions, thereby assisting in land reclamation from different aspects.

[0003] In the prior art, a Chinese patent with authorization announcement number CN216142004U discloses a double-layer structure drainage ditch for land reclamation. Through the coordinated use of the first drainage ditch, the second drainage ditch and the second leak plate, the drainage ditch cannot be used normally due to garbage blockage, and the time for manual cleaning of the drainage ditch is reduced. By setting the coordinated use of the support plate, the first leak plate, the support frame and the placement frame, it is possible to avoid the direct accumulation of mud and sand at the bottom of the drainage ditch, which makes it inconvenient for workers to clean, thereby improving work efficiency.

[0004] The above-mentioned existing technical solutions have the following defects: the volume of the placement frames is very limited and the number is large, which means that when using the above-mentioned double-layer structure drainage ditch, not only the staff needs to clean it frequently, but also the staff needs to repeatedly pick up many placement frames at one time, resulting in a huge workload for the staff and high manpower maintenance costs for the drainage ditch.

[0005] For this reason, a double-layer structure drainage ditch for land reclamation is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problems mentioned in the above background technology. The utility model provides a double-layer structure drainage ditch for land reclamation.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A double-layer drainage ditch for land reclamation comprises an outer drainage trough and an inner filter trough, wherein the tops of the front and rear sides of the inner filter trough are fixedly installed with mounting frames, and the mounting frames are placed in close contact with the top surfaces of the front and rear side walls of the outer drainage trough, and the front and rear side walls and surfaces of the outer drainage trough are provided with limiting handle assemblies for fixing the mounting frames, and a sand accumulation slope is fixedly installed on the bottom surface of the outer drainage trough, and a sand storage drawer is placed in close contact with the top surface of the sand accumulation slope and the bottom surface of the outer drainage trough, and the bottom wall of the inner filter trough is provided with filtering holes, and a discharge plate is provided on the lower side of the inner filter trough, and elastic lifting assemblies for connecting the discharge plate are provided on the surfaces of the left and right side walls of the inner filter trough.

[0009] Furthermore, the sand accumulation slope is arranged from low to high along the direction of water flow, a slot is opened on the top surface of the sand accumulation slope, a plug rod is fixedly installed on the bottom surface of the sand storage drawer, the plug rod is slidably inserted in the slot, and lifting handles are fixedly installed on the front and rear sides of the inner wall of the sand storage drawer.

[0010] Furthermore, the limit handle assembly includes a lifting handle, which is slidably inserted into the top surface of the erection frame, and a limit block is fixedly installed on the bottom surface of the lifting handle. The top surface of the erection frame is provided with a handle groove for accommodating the lifting handle, and the top surfaces of the front and rear side walls of the external drainage groove are both provided with insertion holes, and the limit block is slidably arranged relative to the inner wall surface of the insertion hole.

[0011] Furthermore, the discharge plate comprises a plate body, a dredging rod is fixedly mounted on the surface of the plate body, and a water leakage hole is opened on the surface of the plate body.

[0012] Furthermore, the number of the filter holes is several and evenly distributed, the dredging rod is arranged directly below the filter holes, and the diameter of the dredging rod is not larger than the inner diameter of the filter holes.

[0026] like Figures 1 to 4 As shown, a double-layer drainage ditch for land reclamation includes an outer drainage trough 1 and an inner filter trough 4. The tops of the front and rear sides of the inner filter trough 4 are fixedly installed with mounting frames 5, and the mounting frames 5 are placed in close contact with the top surfaces of the front and rear side walls of the outer drainage trough 1. The front and rear side walls and surfaces of the outer drainage trough 1 are provided with limiting handle assemblies 6 for fixing the mounting frames 5. A sand accumulation slope 2 is fixedly installed on the bottom surface of the outer drainage trough 1, and a sand storage drawer 3 is placed in close contact with the top surface of the sand accumulation slope 2 and the bottom surface of the outer drainage trough 1. A filtering hole 9 is opened on the bottom wall of the inner filter trough 4, a discharge plate 7 is provided on the lower side of the inner filter trough 4, and elastic lifting assemblies 8 for connecting the discharge plate 7 are provided on the surfaces of the left and right side walls of the inner filter trough 4.

[0027] More specifically, the inner filter tank 4 is used to filter larger garbage, such as stones, leaves, plastic bags, etc. The water filtered by the inner filter tank 4 flows in the outer drainage tank 1, and then the morphological and structural characteristics of the sand accumulation slope 2 and the sand storage drawer 3 are used to make the sand that cannot be filtered out accumulate in the sand storage drawer 3 with the water flow. The sand storage drawer 3 has the advantages of large capacity and low cleaning frequency. When it is necessary to clean the sand and garbage in the inner filter tank 4, the inner filter tank 4, the mounting frame 5, the discharge plate 7 and the elastic lifting component 8 can be lifted together by grasping the limit handle assembly 6, and then the sand storage drawer 3 can be taken out to quickly discharge the sand, and the inner filter tank 4 can be turned upside down, and the discharge plate 7 is stepped down so that the discharge plate 7 punctures the filter hole 9, so that the filter hole 9 can be dredged, and the garbage attached to the bottom wall of the inner filter tank 4 is forced to be pushed off, thereby completing the rapid dredging and cleaning of the inner filter tank 4, and the cleaning of garbage and sand is fast and convenient, and the cleaning frequency is low, which greatly reduces the manpower cost required for maintaining the drainage ditch.

[0028] The sand accumulation slope 2 is arranged from low to high along the direction of water flow. A slot 12 is opened on the top surface of the sand accumulation slope 2. An insertion rod 11 is fixedly installed on the bottom surface of the sand storage drawer 3. The insertion rod 11 is slidably inserted into the slot 12. Lifting handles 10 are fixedly installed on the front and rear sides of the inner wall of the sand storage drawer 3.

[0029] Specifically, by sliding the insertion rod 11 into the slot 12, the sand storage drawer 3 can be limited and fixed to prevent the sand storage drawer 3 from shifting under the action of water flow, thereby ensuring that sand is deposited in the sand storage drawer 3. When sand needs to be discharged, the sand storage drawer 3 can be taken out upward by grasping the lifting handle 10, which is quick and convenient.

[0030] The limit handle assembly 6 includes a lifting handle 602, which is slidably inserted into the top surface of the mounting frame 5, and a limit block 603 is fixedly installed on the bottom surface of the lifting handle 602. A handle groove 601 for accommodating the lifting handle 602 is opened on the top surface of the mounting frame 5, and a socket 604 is opened on the top surface of the front and rear side walls of the external drainage trough 1. The limit block 603 is slidably arranged relative to the inner wall surface of the socket 604.

[0031] Specifically, the lifting handle 602 slidingly arranged on the surface of the mounting frame 5 can be lifted and lowered smoothly. When the inner filter tank 4 needs to be lifted, the lifting handle 602 is grasped and driven to move upward, and then the inner filter tank 4 can be lifted. The limit block 603 is used to prevent the lifting handle 602 from slipping off the surface of the mounting frame 5. When the limit block 603 is located in the insertion hole 604, the mounting frame 5 and the outer drainage trough 1 are relatively connected by the lifting handle 602 and the limit block 603, thereby completing the fixation of the inner filter tank 4 and preventing the inner filter tank 4 from moving left and right. The handle groove 601 is used to accommodate the lifting handle 602 to prevent the lifting handle 602 from protruding and tripping pedestrians, which is not only more beautiful but also safer.

[0032] The discharge plate 7 comprises a plate body 701 , a dredging rod 703 is fixedly mounted on the surface of the plate body 701 , and a water leakage hole 702 is opened on the surface of the plate body 701 .

[0033] Specifically, the water passing through the filter hole 9 flows to the surface of the plate body 701, and flows into the outer drainage trough 1 through the leakage hole 702. When the dredging rod 703 approaches and passes through the filter hole 9, the filter hole 9 can be dredged and the garbage adhering to the bottom wall of the inner filter tank 4 can be pushed away, so as to more thoroughly clean the garbage in the inner filter tank 4.

[0034] There are several filter holes 9 which are evenly distributed. The dredging rod 703 is arranged directly below the filter holes 9 . The diameter of the dredging rod 703 is not larger than the inner diameter of the filter holes 9 .

[0035] Specifically, the dredging rod 703 is moved upward through the filter hole 9 to dredge the filter hole 9 and to push away the garbage adhering to the bottom wall of the inner filter tank 4 .

[0036] The elastic lifting component 8 includes a lifting groove 801, which is opened inside the side wall of the inner filter groove 4. A limiting slider 802 is slidably installed in the lifting groove 801. A lifting connecting plate 803 is fixedly installed on the bottom surface of the limiting slider 802. The lifting connecting plate 803 is slidably inserted into the bottom surface of the inner filter groove 4. The bottom surface of the lifting connecting plate 803 is fixedly connected to the top surface of the plate body 701. A spring 804 is fixedly connected between the top surface of the limiting slider 802 and the top surface of the lifting groove 801. The number of elastic lifting components 8 is at least two and they are symmetrically arranged.

[0037] Specifically, when the inner filter tank 4 is flipped over, the discharge plate 7 is located above the inner filter tank 4. The pedal body 701 is pressed downward to allow the dredging rod 703 to pass through the filter hole 9, dredging the filter hole 9 and further assisting in cleaning the garbage in the inner filter tank 4. At this time, the lifting connecting plate 803 moves downward, and the limiting slider 802 slides downward along the inner wall surface of the lifting tank 801, so that the spring 804 is compressed. When the inner filter tank 4 is returned to the normal state, the discharge plate 7 is below the inner filter tank 4, and the spring 804 returns to its natural state. The limiting slider 802 and the lifting connecting plate 803 move downward, so that there is enough space between the plate body 701 and the bottom wall of the inner filter tank 4 for water to flow.

[0038] In summary, the inner filter tank 4 is used to filter larger garbage, such as stones, leaves, plastic bags, etc. The water filtered by the inner filter tank 4 flows in the outer drainage tank 1, and then the morphological and structural characteristics of the sand accumulation slope 2 and the sand storage drawer 3 are used to make the sand that cannot be filtered out accumulate in the sand storage drawer 3 with the water flow. The sand storage drawer 3 has the advantages of large capacity and low cleaning frequency. When it is necessary to clean the sand and garbage in the inner filter tank 4, the inner filter tank 4, the mounting frame 5, the discharge plate 7 and the elastic lifting component 8 can be lifted together by grasping the limit handle assembly 6, and then the sand storage drawer 3 can be taken out to quickly discharge the sand, and the inner filter tank 4 can be turned upside down, and the discharge plate 7 can be stepped down to make the discharge plate 7 pierce the filter hole 9, so that the filter hole 9 can be dredged, and the garbage attached to the bottom wall of the inner filter tank 4 can be forced to be pushed off, thereby completing the rapid dredging and cleaning of the inner filter tank 4, and the cleaning of garbage and sand is fast and convenient, and the cleaning frequency is low, which greatly reduces the manpower cost required for maintaining the drainage ditch.
