Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and specifically provides a slope protection device that can reduce the impact force of water flow. Background Art

[0002] Slope protection devices are engineering facilities used to prevent natural disasters such as slope landslides, collapses, and debris flows. Their main function is to enhance the stability of slopes through reasonable design and layout, protect the surrounding environment and infrastructure. On slope protection devices, measures such as planting grass are taken to enhance the soil's erosion resistance and improve the natural stability of slopes. In order to irrigate the vegetation, porous water pipes for drip irrigation are usually installed on slope protection devices. By supplying water regularly, it can meet the water requirements of plants during the growth process, promote root development and the healthy growth of plants, thereby enhancing the vegetation coverage of slopes.

[0003] On existing slope protection devices, equally spaced porous water pipes or spray heads are installed for drip irrigation or irrigation of vegetation. The irrigation method using spray heads will cause unnecessary water loss and increase water consumption. Therefore, the drip irrigation method is mostly used. However, when the water flow transmission pressure is relatively large, the water droplets flowing out from the drip irrigation of porous water pipes are relatively large, and the porous water pipes at fixed positions only irrigate the same position for a long time, which is likely to increase the impact force of water flow on the soil or vegetation, making the water unable to fully cover the soil, being unfavorable for vegetation growth, and reducing the protection performance of the slope protection device. For this reason, we propose a slope protection device that can reduce the impact force of water flow. Summary of the Invention

A moving groove is opened in the inner side of the fixing frame close to the second round rod, and the second round rod is slidably connected with the moving groove. A main pipe is fixedly penetrated through the inner side of the connecting frame. The main pipe is connected to the pressure pump through a hose. Below the main pipe, a plurality of porous drip irrigation pipes are fixed at equal intervals. A buffer mechanism is installed below the porous drip irrigation pipe. The buffer mechanism includes a rotating shaft connected to the bottom end of the porous drip irrigation pipe through a bearing. A paddle and a buffer plate are fixedly sleeved on the outer side of the rotating shaft, and the buffer plate is located below the rotating shaft. A bent pipe is connected to one side of the porous drip irrigation pipe. A baffle is fixedly sleeved at one end of the bent pipe close to the paddle.

[0006] Preferably, a motor is fixedly installed on the inner side of the moving frame. One end of the motor is connected with a gear through a coupling. A rack is fixed on the inner side of the fixing frame close to the gear, and the gear is meshed with the rack.

[0007] Preferably, a spacer is cast on the surface of the slope protection body with concrete. Drainage grooves are opened on both sides of the slope protection body. A filter screen is arranged on the inner side of the drainage groove close to the bottom groove.

[0008] Preferably, an installation frame is fixed in the middle of the bottom end of the slope protection body. Flipping mechanisms are arranged on both sides of the slope protection body close to the installation frame, and one side of the flipping mechanism is connected with the filter screen. Docking blocks are fixed on both sides of the filter screen.

[0009] Preferably, docking grooves are opened on the inner wall of the slope protection body close to the docking blocks. A cross frame is fixed in the middle of the slope protection body close to the spacer with concrete.

[0010] Preferably, a guiding groove is opened inside the cross frame. A slider is slidably sleeved on the inner side of the guiding groove. A telescopic rod is fixed above the slider. The top end of the telescopic rod is fixed with a guiding frame, and the guiding frame is fixedly sleeved with the main pipe.

[0011] Preferably, a screw rod is installed in an inner groove of the installation frame through a bearing. A rotating handle is fixedly sleeved at one end of the screw rod. A lifting block is threadedly sleeved on the outer side of the screw rod. Guide rods are connected to both sides of the lifting block through bearings.

[0012] Preferably, the guide rod slidably penetrates through both sides of the mounting frame. The flipping mechanism includes side plates fixedly connected to the slope protection body, and strip-shaped grooves are formed inside the side plates.

[0013] Preferably, arc-shaped grooves are formed inside the side plates near the top ends of the strip-shaped grooves. A first round rod is slidably connected inside the strip-shaped grooves, and a lifting frame is fixedly connected to one side of the first round rod.

[0014] Preferably, an L-shaped rod is connected between the side of the lifting frame away from the first round rod and the filter screen. The end of the guide rod away from the lifting block is connected to the middle of the lifting frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For the slope protection device capable of reducing the water flow impact force, during the drip irrigation process, the motor drives the gear to rotate, causing the gear to rotate and move on the rack, driving the moving frame to move on the fixed frame. At the same time, the second round rod slides along the moving groove, enabling the connecting frame to drive the main pipe to move horizontally and reciprocate up and down, which can further refine the distribution of water. Through the reciprocation, disturbances will be generated inside the water body, and water droplets can be effectively split into smaller water droplets. Moreover, the buffer mechanism disperses and buffers the water flow sprayed out from the porous drip irrigation pipe. The rotating paddle blades collide with the water droplets, and the water droplets can be split into smaller water beads again to reduce the impact force of the drip irrigation water flow on the vegetation, avoid excessive water flow impact force from damaging the vegetation, and at the same time achieve a more uniform irrigation effect, which is beneficial to the growth of the vegetation of the slope protection device.

[0016] 1. For the slope protection device capable of reducing the water flow impact force, when drip-irrigating the vegetation on the slope protection, the motor drives the gear to rotate. The gear rotates and moves to one side on the rack. Subsequently, the moving frame moves along with the gear, and the connecting frame moves along with the moving frame. The connecting frame drives the main pipe to move. The middle part of the main pipe drives the slider to slide in the guiding groove through the telescopic rod. As the connecting frame moves, the connecting frame drives the second round rod to move, and the second round rod slides along the track of the moving groove. At the same time, the second sliding rod drives the connecting rod to slide up and down inside the moving frame, enabling the main pipe to reciprocate up and down while moving horizontally. The horizontal movement can increase the drip irrigation range and avoid water concentration. When the main pipe reciprocates up and down, it can further refine the distribution of water. Through the reciprocation, disturbances will be generated inside the water body, and water droplets can be effectively split into smaller water droplets, avoiding excessive water flow impact force from damaging the vegetation, and at the same time achieving a more uniform irrigation effect. 2. While the main pipe moves horizontally and reciprocates up and down, the pressure pump transports water into the main pipe through high pressure and sprays it out through the through holes of several porous drip irrigation pipes. After the water is pushed out from the elbow through high pressure, the water impacts the paddle blades. The concave surface of the paddle blades will rotate after being impacted, and the paddle blades drive the rotating shaft to rotate. The rotating shaft then drives the buffer plate to rotate. There are several through holes on the inner side of the buffer plate to facilitate the dispersion and dripping of a small part of the water remaining on the surface of the buffer plate. While the paddle blades and the buffer plate are rotating, the water droplets flowing out from the through holes of the porous drip irrigation pipes are sprayed onto the paddle blades. The rotating paddle blades collide with the water droplets, and the water droplets can be split into smaller water beads again to reduce the impact force of the drip irrigation water flow on the vegetation, which is beneficial for the water to fully contact the soil, promotes the growth of the vegetation, and improves the protection performance of the slope protection device; 3. The slope protection device that can reduce the impact force of water flow filters fallen leaves and stones through a filter screen. Then, the staff regularly rotates the rotating handle, which drives the screw rod to rotate. The lifting block drives the guide rod to rise outside the screw rod, and the guide rod drives the lifting frame to slide and rise in the strip-shaped groove. At the same time, the lifting frame drives the filter screen to rise through the L-shaped rod. When the first round rod reaches the top slope of the strip-shaped groove, the staff gently turns the filter screen clockwise. The filter screen rotates obliquely due to gravity and drives the first round rod to slide into the arc-shaped groove, causing the lifting frame and the guide rod to rotate, which can make the filter screen tilt outward from the bottom groove. Subsequently, the fallen leaves and stones in the filter screen roll down, assisting the staff to clean the drainage groove, preventing the fallen leaves and stones from staying in the drainage groove for a long time, preventing the water from eroding the slope protection device, and extending the protection life of the slope protection device.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , Figure 2 , Figures 7 - 10 and Figure 14 , the present invention provides a technical solution: a slope protection device that can reduce the impact force of water flow, including a slope protection body 1 and a fixing frame 13. A collection water pump 2, a water storage tank 3 and a pressure pump 4 are installed above the slope protection body 1. A bottom groove 9 is provided at the bottom end of the slope protection body 1. A recovery pipe 5 is connected between both ends of the collection water pump 2 and the bottom groove 9. A drainage plate 12 is fixed on the top of the slope protection body 1. The fixing frame 13 is arranged above the drainage plate 12. A spacer 8 is cast on the surface of the slope protection body 1 with concrete. Drainage grooves 10 are opened on both sides of the slope protection body 1.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figures 8 - 11 As shown in, a slide bar 33 is fixed in an internal slot on one side of the fixing frame 13. A moving frame 29 is slidably sleeved on the outer side of the slide bar 33. A connecting frame 14 is slidably sleeved on the inner side of the moving frame 29. A second round bar 34 is connected to one side of the connecting frame 14. A moving slot 32 is formed in the inner side of the fixing frame 13 close to the second round bar 34, and the second round bar 34 is slidably connected to the moving slot 32. A main pipe 7 is fixedly penetrated through the inner side of the connecting frame 14. The main pipe 7 is connected to a pressure pump 4 through a hose. A cross frame 15 is fixed to the middle of the slope protection body 1 close to the spacer plate 8 by concrete. A guiding slot 35 is formed inside the cross frame 15. A slider 23 is slidably sleeved on the inner side of the guiding slot 35. A telescopic rod 22 is fixed above the slider 23. The top end of the telescopic rod 22 is fixed with a guiding frame 19, and the guiding frame 19 is fixedly sleeved with the main pipe 7. A motor 28 is fixedly installed on the inner side of the moving frame 29. One end of the motor 28 is connected with a gear 31 through a coupling. A rack 30 is fixed to the side of the fixing frame 13 close to the gear 31, and the gear 31 is meshed with the rack 30. The moving slot 32 is in a wavy shape.

[0022] During specific implementation, when drip irrigation is carried out on the vegetation on the slope protection, the motor 28 is driven to rotate the gear 31. The gear 31 is meshed with the rack 30, so that the gear 31 rotates on the rack 30 and moves to one side. Subsequently, the moving frame 29 moves along with the gear 31. At the same time, one side of the moving frame 29 slides on the outer side of the slide bar 33. The connecting frame 14 moves along with the moving frame 29. The connecting frame 14 drives the main pipe 7 to move. The middle part of the main pipe 7 drives the slider 23 to slide in the guiding slot 35 through the telescopic rod 22. As the connecting frame 14 moves, the connecting frame 14 drives the second round bar 34 to move. The second round bar 34 is squeezed by the inclined surface of the moving slot 32, so that the second round bar 34 slides along the track of the moving slot 32. At the same time, the second round bar 34 drives the connecting frame 14 to slide up and down on the inner side of the moving frame 29, so that the main pipe 7 can move horizontally and reciprocate up and down at the same time. The horizontal movement can increase the drip irrigation range and avoid water concentration. When the main pipe 7 reciprocates up and down, the distribution of water can be further refined. Through the vibration, disturbances will be generated inside the water body, and the water droplets can be effectively split into smaller water droplets, avoiding excessive water flow impact force on the vegetation and achieving a more uniform irrigation effect at the same time.

[0023] Please refer to Figure 1 、 Figure 4 、 Figure 12 and Figure 13, a porous drip irrigation pipe 21 is fixedly installed below the main pipe 7 at equal intervals. A buffer mechanism 6 is installed below the porous drip irrigation pipe 21. The buffer mechanism 6 includes a rotating shaft 603 connected to the bottom end of the porous drip irrigation pipe 21 through a bearing. A paddle 604 and a buffer plate 605 are fixedly sleeved on the outer side of the rotating shaft 603, and the buffer plate 605 is located below the rotating shaft 603. A bent pipe 601 is connected to one side of the porous drip irrigation pipe 21. A baffle 602 is fixedly sleeved at one end of the bent pipe 601 close to the paddle 604. A plurality of through holes are provided inside the buffer plate 605.

[0024] During specific implementation, while the main pipe 7 moves horizontally and reciprocates up and down, the pressure pump 4 transports water flow into the main pipe 7 through high pressure and sprays it out through the through holes of a plurality of porous drip irrigation pipes 21. Since the bent pipe 601 is located on one side of the porous drip irrigation pipe 21, after the water flow is pushed out from the bent pipe 601 through high pressure, the water flow impacts the paddle 604. After the concave surface of the paddle 604 is impacted, it will rotate. The paddle 604 drives the rotating shaft 603 to rotate, and the rotating shaft 603 drives the buffer plate 605 to rotate. The baffle 602 blocks the water flow ejected from the bent pipe 601 to prevent the water flow from splashing too far when impacting the paddle 604, reducing water loss. A plurality of through holes are provided inside the buffer plate 605 to facilitate the dispersed dripping of a small part of the water retained on the surface of the buffer plate 605. While the paddle 604 and the buffer plate 605 are rotating, the water droplets flowing out from the through holes of the porous drip irrigation pipe 21 are sprayed onto the paddle 604. The rotating paddle 604 collides with the water droplets, and the water droplets can be split into smaller water beads again to reduce the impact force of the drip irrigation water flow on the vegetation, which is beneficial for the water to fully contact the soil, promotes the growth of the vegetation, and improves the protection performance of the slope protection device.

[0025] Please refer to Figures 1 - 3 , Figures 5 - 7 and Figure 14A filter screen 11 is provided on the inner side of the drainage trough 10 near the bottom trough 9, a mounting frame 17 is fixed to the middle part of the bottom end of the slope protection body 1, a flip mechanism 16 is provided on both sides of the slope protection body 1 near the mounting frame 17, and one side of the flip mechanism 16 is connected to the filter screen 11, docking blocks 20 are fixed on both sides of the filter screen 11, a docking groove 36 is provided on the inner wall of the slope protection body 1 near the docking block 20, a screw rod 27 is installed in the built-in groove of the mounting frame 17 through a bearing, a rotating handle 25 is fixedly sleeved on one end of the screw rod 27, a lifting block 26 is threadedly sleeved on the outer side of the screw rod 27, and guide rods 18 are connected to both sides of the lifting block 26 through bearings, and the guide rods 18 slide through both sides of the mounting frame 17, and the flip mechanism 16 includes It includes a side plate 1601 fixedly connected to the slope protection body 1, a strip groove 1603 is provided on the inner side of the side plate 1601, an arc groove 1602 is provided on the inner side of the side plate 1601 near the top of the strip groove 1603, a No. 1 round rod 24 is slidably connected to the inner side of the strip groove 1603, a lifting frame 1604 is fixedly connected to one side of the No. 1 round rod 24, an L-shaped rod 1605 is connected between the side of the lifting frame 1604 away from the No. 1 round rod 24 and the filter 11, the end of the guide rod 18 away from the lifting block 26 is connected to the middle part of the lifting frame 1604, the docking block 20 matches the size of the docking groove 36, the top of the strip groove 1603 is provided with an inclined surface, and the No. 1 round rod 24 is located at both ends of the lifting frame 1604.

[0026] In specific implementation, since grooves for drainage are usually provided on both sides of the slope protection device, fallen leaves and stones will fall into the grooves and need to be cleaned in time. The fallen leaves and stones will be retained in the drainage grooves 10 for a long time, which will make it impossible for rainwater to be discharged quickly. The long-term retention of water will cause erosion to the slope protection device and reduce the protection life of the slope protection device. The fallen leaves and stones can be filtered through the filter screen 11, and then the staff will regularly turn the handle 25 to make the handle 25 drive the screw rod 27 to rotate, and then the screw 27 and the lifting block 26 are threadedly engaged, so that the lifting block 26 drives the guide rod 18 to rise on the outside of the screw 27, and the guide rod 18 drives the lifting frame 1604 to slide and rise in the strip groove 1603. The lifting frame 1604 drives the filter screen 11 to rise through the L-shaped rod 1605, so that the docking block 20 is separated from the docking groove 36. When the No. 1 round rod 24 reaches the top slope of the strip groove 1603, the staff slightly moves the filter screen 11 clockwise. The filter screen 11 rotates tilted due to gravity and drives the No. 1 round rod 24 to slide into the arc groove 1602, so that the lifting frame 1604 and the guide rod 18 rotate, which can make the filter screen 11 tilt toward the outside of the bottom groove 9. Then the fallen leaves and stones in the filter screen 11 roll down, assisting the staff to clean the drainage groove 10, avoiding the fallen leaves and stones from being trapped in the drainage groove 10 for a long time, preventing moisture from eroding the slope protection device, and extending the protection life of the slope protection device.

[0027] In summary, when using the slope protection device that can reduce the impact force of water flow, the drainage groove 10 is used to drain rainwater. The rainwater drained from the drainage groove 10 reaches the bottom groove 9 for collection. The filter screen 11 filters fallen leaves and stones. Subsequently, the collection water pump 2 drives the recovery pipe 5 to extract rainwater from the bottom groove 9, so that the rainwater enters the water storage tank 3 for collection. When drip irrigation is required for vegetation, water can be sucked from the water storage tank 3 through the pressure pump 4 and discharged into the main pipe 7 through the hose, and finally sprayed out through a number of porous drip irrigation pipes 21. During the drip irrigation process, the motor 28, gears 31 and rack 30 drive the moving frame 29 to move horizontally, and the moving groove 32 drives the connecting frame 14 to reciprocate up and down. At the same time, the buffer mechanism 6 buffers and disperses the sprayed water droplets, so that the water droplets are split into smaller water droplets, avoiding the impact on the vegetation caused by excessive water flow, improving the stability of the slope soil. When the filter screen 11 needs to be cleaned, the filter screen 11 can be lifted and flipped by rotating the turning handle 25 to drive the flipping mechanism 16, which is beneficial to quickly clean the filter screen 11, prevent water from staying in the drainage groove 10 for a long time, reduce the erosion of the slope protection device, and improve the protection performance of the slope protection device.
