Description

Technical Field

[0001] The present invention relates to the technical field of ditch slope protection, in particular to an erosion-resistant ditch slope protection for water conservancy projects. Background Art

[0002] Agricultural planting is one of the important industries to ensure food production. During the agricultural planting process, in order to facilitate the irrigation of farmland, ditches are generally opened for drainage, and water from rivers and lakes is led to farmland for irrigation. The current ditches usually dig a trench on the soil base, and then water is led into the trench to form a trench for farmland irrigation. However, since the bottom of the trench does not have any waterproof measures, when the water flows in the trench, a large part of the water flow will extend into the ground, causing the ditch to dry up frequently, seriously affecting the irrigation of crops. Therefore, slope protection is often set on the ditch slope for protection to avoid soil and water runoff.

[0003] In the existing technology, existing slope protection is often fixed with cement. However, in areas with relatively soft soil, cement fixation is not effective. As a result, the slope protection becomes loose after long-term use, which affects the protection of the ditch. To this end, we propose an erosion-resistant ditch slope protection for water conservancy projects. Existing slope protection is not corrosion-resistant and is prone to leakage after long-term use.

[0010] In the above-mentioned erosion-resistant ditch slope protection of the water conservancy project, the driving mechanism also includes a retention groove opened in the top wall of the fixed main body, the bottom wall of the retention groove is rotatably connected to an annular plate through a bearing, and a number of second springs are fixedly connected between the annular plate and the lower surface of the operating block.

[0015] Compared with the existing technology, the advantages of the present invention are:

[0016] 1. The rotation of the threaded barrel causes the screw to move, thereby driving the fixed block to be inserted into the soil. As the insertion continues to go deeper, the soil layer gradually becomes denser, which causes the pressure on the protective cover to continue to increase. The pressure on the protective cover is transmitted to the sliding plate through the top column, causing the pressure in the liquid cavity to continue to increase until it reaches the critical value of the pressure relief valve, causing the pressure relief valve to open, and the hydraulic oil to be pressed into the sliding groove, causing the sliding sleeve and the fixing pin to slide out and insert horizontally into the denser soil, thereby making the slope protection more firmly fixed;

[0017] 2. The setting of anti-seepage layer and waterproof bonding layer makes the slope protection more corrosion-resistant and effectively avoids the occurrence of seepage;

[0018] 3. Through the arrangement of the rotating cylinder, rotating rod, cam and connecting groove, the operating block can be pulled out for operation during the fixing operation. When the fixing is completed, the operating block can be placed in the retention groove, so that the operating block is protected after the fixing is completed to avoid the loosening of the fixing due to accidental contact of the operating block.

[0019] 4. By setting the size of the first gear and the second gear, it is easier to fix the slope with less effort, that is, a larger fixing force can be produced with less force, thereby ensuring the stability of the slope protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0030] Example

[0031] Reference Figure 1-8 A water conservancy project erosion-resistant ditch slope protection includes a compacted layer 32 and two hollow fixed bodies 1. The two side walls of the compacted layer 32 are respectively fixedly connected to one of the fixed bodies 1. The two sides of the compacted layer 32 are fixed by the two fixed bodies 1. The compacted layer 32 is fixed to the soil by cement, thereby fixing the slope protection by the dual fixing method of the fixed bodies 1 and the cement, ensuring its stability. A fixing mechanism is provided in the fixed body 1.

[0032] The fixing mechanism includes a threaded barrel 2 which is rotatably connected to the fixing body 1 through a bearing, the threaded barrel 2 is threadedly connected to a screw 3, the bottom end of the screw 3 is fixedly connected to a fixing block 4, and a liquid chamber 5, four sliding grooves 9 and a connecting chamber 11 are provided in the fixing block 4. Figure 4As shown, the four sliding grooves 9 and the connecting cavity 11 are evenly distributed, and the angle between each sliding groove 9 and the connecting cavity 11 is 90 degrees, so as to ensure that the fixing pins 14 are horizontally pinned into the soil in all four directions. The connecting cavity 11 connects the liquid cavity 5 with the corresponding sliding groove 9. A pressure relief valve 12 is provided in the connecting cavity 11. The pressure relief valve 12 can be opened after the pressure reaches a certain value, thereby controlling the sliding sleeve 10 and the fixing pin 14 to slide out through the pressure relief valve, so that the sliding sleeve 10 and the fixing pin 14 can slide out only when they reach the required soil layer, thereby ensuring It proves that no matter what depth the dense soil is located, the slope protection can be stably fixed. A pump plate 8 is sealingly and slidingly connected in the liquid cavity 5, a protective cover 6 is slidingly connected in the fixed block 4, a top column 7 is welded to the bottom wall of the protective cover 6, the top column 7 is slidingly connected to the bottom wall of the fixed block 4, the top column 7 extends into the liquid cavity 5 and is welded to the lower surface of the pump plate 8, a sliding sleeve 10 is sealingly and slidingly connected in the sliding groove 9, a fixing pin 14 is sealingly and slidingly connected in the sliding sleeve 10, a through hole 13 is opened in the end wall of the sliding sleeve 10, and the liquid cavity 5 is filled with hydraulic oil.

[0033] An anti-seepage layer 33 is fixedly connected to the upper surface of the compacted layer 32, a waterproof adhesive layer 34 is provided on the upper surface of the anti-seepage layer 33, and a concrete layer 35 is provided on the upper surface of the waterproof adhesive layer 34. The anti-seepage layer 33 and the waterproof adhesive layer 34 increase the corrosion resistance of the slope protection, thereby avoiding leakage.

[0034] The bottom wall of the fixed block 4 is provided with an annular groove 17, and the protective cover 6 is slidably connected to the fixed block 4 through the annular groove 17. A plurality of first springs 18 are fixedly connected between the protective cover 6 and the inner top wall of the annular groove 17. The lower surface of the protective cover 6 is welded with a tunneling block 19. Figure 3 As shown, the excavation block 19 is tapered, so that the fixing block 4 can be more easily inserted into the soil through the tip of the excavation block 19 and penetrate deep into the soil.

[0035] A driving mechanism for driving the threaded cylinder 2 to rotate is provided in the fixed body 1. The driving mechanism includes a rotating cylinder 21. The rotating cylinder 21 is rotatably connected to the inner bottom wall of the fixed body 1 through a bearing. The rotating cylinder 21 is interference-fitted with a second gear 23. A section of the threaded cylinder 2 located in the fixed body 1 is interference-fitted with a first gear 20. The first gear 20 is engaged with the second gear 23. The rotating cylinder 21 is slidably sleeved with a rotating rod 24. The rotating rod 24 passes through the top wall of the fixed body 1 and extends to the outside thereof. An operating block 26 is welded to one end of the rotating rod 24 located outside the fixed body 1. Figure 8As shown, the cross-section of the operating block 26 is a regular hexagon, so that the operating block 26 can be operated more conveniently and quickly by using tools such as wrenches and sockets. A number of ridges 25 are welded to the side wall of the rotating rod 24, and a number of connecting grooves 22 are opened on the inner wall of the rotating cylinder 21. The ridges 25 are slidably connected to the rotating cylinder 21 through the connecting grooves 22. Through the arrangement of the ridges 25 and the connecting grooves 22, the rotating rod 24 can both slide relative to the rotating cylinder 21 and drive the rotating cylinder 21 to rotate.

[0036] The driving mechanism also includes a retaining groove 27 provided in the top wall of the fixed body 1, and the bottom wall of the retaining groove 27 is rotatably connected to an annular plate 28 through a bearing. A number of second springs 29 are fixedly connected between the annular plate 28 and the lower surface of the operating block 26. A number of locking grooves 31 are provided on the side wall of the operating block 26, and a locking pin 30 is slidably connected to the side wall of the fixed body 1, and the locking pin 30 extends through the retaining groove 27.

[0037] The inner wall of the sliding groove 9 and the inner wall of the sliding sleeve 10 are both provided with a limiting groove 15, and the limiting block 16 is sealed and slidably connected in the limiting groove 15. The limiting block 16 is welded to the corresponding side wall of the sliding sleeve 10 and the fixing pin 14. Through the setting of the limiting groove 15 and the limiting block 16, the sliding sleeve 10 and the fixing pin 14 are limited to a certain extent, thereby avoiding excessive sliding, and the fixing pin 14 slipping out of the sliding sleeve 10 or the sliding sleeve 10 sliding into the sliding groove 9.

[0038] The size of the second gear 23 is smaller than that of the first gear 20. When the rotating cylinder 21 is rotated so that the second gear 23 drives the first gear 20, the fixing block is lowered through the threaded connection, which is more labor-saving. That is, a larger fixing force can be generated with less force, thereby ensuring the stability of the slope protection.

[0039] The thread lead angle of the screw 3 is smaller than the equivalent friction angle of the spiral pair formed by the screw 3 and the threaded barrel 2, so that the threaded connection between the screw 3 and the threaded barrel 2 is self-locking, thereby avoiding shaking at the threaded connection and affecting the stability of the fixation. A sealing gasket is provided at the threaded connection between the screw 3 and the threaded barrel 2 to ensure the sealing of the threaded connection, thereby preventing rainwater from leaking from the threaded connection.

[0040] The bearing between the threaded cylinder 2 and the fixed body 1 is a sealed bearing, and a sealing gasket is provided between the upper surface of the rotating cylinder 21 and the inner top wall of the fixed body 1. The sealed bearing prevents rainwater from entering the fixed body 1 from the bearing connection and affecting the internal structure. The sealing gasket prevents rainwater from leaking into the interior of the fixed body 1 from the penetration point of the rotating rod 24 and affecting the internal structure.

[0041] In the present invention, the position of the fixed body 1 is determined. After the position is determined, the locking pin 30 is pulled, so that the locking pin 30 slides out of the locking groove 31, and the lock on the operating block 26 is released, so that the operating block 26 slides out of the retention groove 27 under the elastic force of the second spring 29;

[0042] The operating block 26 is rotated by a tool such as a wrench or a socket, thereby rotating the rotating rod 24, and the rotating rod 24 drives the rotating cylinder 21 to rotate, thereby rotating the second gear 23 which is in interference fit with the rotating cylinder 21. The rotation of the second gear 23 drives the first gear 20 which is meshed with it to rotate, thereby rotating the threaded cylinder 2 which is in interference fit with the first gear 20. The rotation of the threaded cylinder 2 causes the screw 3 to drive the fixed block 4 downward through the threaded connection and insert it into the soil. The fixed block 4 is continuously penetrated into the soil through the excavation block 19 until it penetrates deep into the soil and reaches a position with relatively dense soil.

[0043] At this time, due to the denser soil, the downward resistance of the protective cover 6 continues to increase, and the resistance is transmitted to the pump plate 8 through the protective cover 6 and the top column 7, so that the pressure of the hydraulic oil in the liquid chamber 5 continues to increase until it reaches the critical value of the pressure relief valve 12. At this time, it means that the soil in this layer has met the requirements for firmly fixing the slope protection.

[0044] As the pressure relief valve 12 opens, the hydraulic oil enters the sliding groove 9 through the communicating chamber 11, causing the sliding sleeve 10 to slide outward from the sliding groove 9. Simultaneously, the hydraulic oil enters the sliding sleeve 10 through the through hole 13, causing the fixing pin 14 in the sliding sleeve 10 to slide outward from the sliding sleeve 10, thereby causing the fixing pin 14 to be laterally inserted into the soil of the layer. The lateral insertion of the fixing pin 14 firmly fixes the fixing body 1 to the soil, thereby firmly fixing the slope protection.

[0045] After the fixation is completed, the operating block 26 is pressed downward into the retention groove 27, and the locking pin 30 is pushed at the same time so that the locking pin 30 is inserted into the locking groove 31 of the operating block 26, and the operating block 26 is locked in the retention groove 27, thus completing the fixation.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
