DETAILED DESCRIPTION

[0027] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 As shown, a docking protrusion 9 is fixedly connected to the front surface of the slope protection body 1, and a splicing groove 10 is opened on the rear surface of the slope protection body 1;

[0030] The slope protection body 1 can be quickly spliced ​​and installed by means of the butt joint protrusions 9 and the splicing grooves 10, which can greatly improve the construction efficiency and shorten the construction period in the construction of water conservancy projects.

[0031] like Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, a filtering mechanism 3 is arranged on the right side of the slope protection body 1, and the filtering mechanism 3 includes a water inlet 301, and a filter screen 302 is fixedly connected to the inner upper surface and the lower surface of the water inlet 301, and a through-type circulation groove 303 is opened between the inner left side of the water inlet 301 and the water storage chamber 4, and a rotating column 304 is arranged inside the circulation groove 303, and a plurality of toggle plates 305 are fixedly connected to the outer wall of the rotating column 304, and an extrusion cavity 306 is integrally formed inside the slope protection body 1 and located in front and behind the circulation groove 303, and a piston plate 2 307 is slidably connected to the inside of the two extrusion cavities 306, and a connecting rod 308 is fixedly connected at the center of the front surface and the center of the rear surface of the rotating column 304, and the opposite ends of the two connecting rods 308 extend to the inside of the two extrusion cavities 306 respectively, and are fixedly connected to a cam 2 309, and the interior of the slope protection body 1 and located below the two extrusion cavities 306 are uniformly A ventilation chamber 310 is formed on the body, and piston plates 311 are slidably connected to the upper parts of the two ventilation chambers 310. Pressing rods 312 are fixedly connected between the upper surfaces of the two piston plates 311 and the lower surfaces of the two piston plates 2 307, respectively. A sliding box 313 is fixedly connected to the right side of the slope protection body 1 and located in front and behind the filter screen 302. Piston plates 4 314 are slidably connected to the interiors of the two sliding boxes 313. Extension rods 315 are fixedly connected to the left sides of the two piston plates 4 314. The left ends of the two extension rods 315 extend to the left sides of the two sliding boxes 313, respectively, and are fixedly connected to a cleaning plate 316. A brush 317 is detachably connected to the lower surface of the cleaning plate 316. Gas hoses 2 318 are fixedly connected to the right sides of the two sliding boxes 313. The ends of the two gas hoses 2 318 away from the two sliding boxes 313 are fixedly connected to the interiors of the two ventilation chambers 310, respectively.

[0032] When water flows in from the water inlet 301, large particles of impurities in the water flow are filtered through the filter screen 302, and the filtered water enters the water storage chamber 4 through the circulation slot 303. As a result, under the push of the water flow, multiple toggle plates 305 are forced to rotate, driving the rotating column 304 to rotate, and at the same time driving the two connecting rods 308 to rotate, thereby causing the two cams 309 to rotate at the same time. The rotation of the two cams 309 will push the two piston plates 307 to move up and down in the two extrusion chambers 306. When the two piston plates 307 move downward, the two pressing rods 312 push the two piston plates 307 to slide downward in the two ventilation chambers 310, so that the two ventilation chambers 310 are moved upward and downward. The air in the air cavity 310 is pressed into the two sliding boxes 313 through two air supply hoses 318, thereby pushing the two piston plates 314 to move leftward in the two sliding boxes 313, and then driving the cleaning plate 316 to move leftward through the two extension rods 315, and the movement of the cleaning plate 316 can drive the brush 317 to clean the filter 302. When the two cams 309 and the two piston plates 307 are no longer in contact, the cleaning plate 316 and the brush 317 are driven to reset under the action of negative pressure, and the brush 317 can be driven by water flow to automatically clean the filter 302, which helps to improve the stability and reliability of the device and reduce the maintenance cost of the device.

[0033] like Figure 6 As shown, the lower surfaces of the two piston plates 311 are respectively fixedly connected to the inner lower surfaces of the two ventilation chambers 310 with a plurality of springs 2 319;

[0034] When the two cams 309 rotate and lose contact with the two piston plates 307, the rebound of the multiple springs 319 can make the two piston plates 307 quickly return to their initial positions, ensuring that the entire device can periodically clean the filter screen 302 more stably and efficiently.

[0035] like Figure 2 and Figure 7 As shown, a water storage chamber 4 is integrally formed inside the slope protection body 1, a water pump installation groove 5 is provided on the left side of the slope protection body 1 and above the water storage chamber 4, a water pump body 6 is fixedly connected to the inner upper surface of the water pump installation groove 5, an L-shaped water pumping pipe 7 is fixedly connected to the input end of the water pump body 6, an end of the L-shaped water pumping pipe 7 away from the water pump body 6 extends to the lower part of the water storage chamber 4, an output end of the water pump body 6 is fixedly connected to a delivery hose 8, and the left end of the delivery hose 8 is fixedly connected to the right side of the inside of the spray box 202;

[0036] The water source filtered through the filter net 302 flows to the inside of the water storage chamber 4 through the circulation groove 303. By starting the set water pump body 6 and the L-shaped water suction pipe 7, the water source in the water storage chamber 4 is transported to the inside of the spray box 202 through the set delivery hose 8. The impurities and floating objects in the water can be filtered out through the filter net 302, thereby reducing damage to the water pump body 6 and improving the working efficiency and stability of the water pump body 6.

[0037] like Figure 7 As shown, a sealing ring 11 is fixedly connected to the outer wall of the L-shaped water pump pipe 7 at the place where the water storage chamber 4 and the water pump installation groove 5 are connected;

[0038] The sealing ring 11 can effectively prevent water from leaking out from the connection between the water storage chamber 4 and the water pump installation groove 5, ensuring that the water storage chamber 4 will not leak to the outside of the slope protection body 1, and preventing water in the slope from penetrating to the outside of the slope through the water storage chamber 4, thereby improving the reliability and stability of the device.

[0039] like Figure 1-Figure 3 As shown, a water conservancy project slope protection device is provided, including a slope protection body 1, a spray mechanism 2 is arranged on the left side of the slope protection body 1, the spray mechanism 2 includes two fixed plates 201, the right sides of the two fixed plates 201 are fixedly connected to the upper left side of the slope protection body 1, a spray box 202 is arranged between the opposite sides of the two fixed plates 201, the front surface and the rear surface of the spray box 202 are fixedly connected with connecting columns 203, the opposite ends of the two connecting columns 203 are respectively rotatably connected to the opposite sides of the two fixed plates 201 through a rotating shaft, and the connecting column 203 located in front of the spray box 202 The outer wall of the connecting column 203 is fixedly connected with a transmission gear 204. A driving motor 205 is arranged behind the fixed plate 201 located in front of the spray box 202. The rear end of the output shaft of the driving motor 205 extends to the bottom of the transmission gear 204 and is fixedly connected with a rotating disc 206. The outer wall of the rotating disc 206 is fixedly connected with a rack plate 207. The outer wall of the connecting column 203 located in front of the spray box 202 is sleeved with a torsion spring 208. The two ends of the torsion spring 208 are respectively fixedly connected to the rear surface of the transmission gear 204 and the front surface of the spray box 202;

[0040] When it is necessary to spray and irrigate the plants outside the slope, the water in the water storage chamber 4 is transported to the spray box 202 through the delivery hose 8 through the water pump body 6, and the driving motor 205 is started to drive the rotating disc 206 to rotate, and the rack plate 207 rotates therewith, and the transmission gear 204 can be driven to rotate indirectly through the rotation of the rack plate 207. The rotation of the transmission gear 204 drives the two connecting columns 203 and the spray box 202 to rotate around the rotating shaft, so as to adjust the spraying angle of the spray box 202. During the rotation of the spray box 202, the torsion spring 208 is gradually twisted to store elastic potential energy. When the rack plate 207 and the transmission gear 204 are no longer engaged, the torsion spring 208 releases the elastic potential energy and drives the spray box 202 back to the initial position, so that the plants outside the slope can be better irrigated, the soil surface can maintain a certain humidity, and the cohesion of the soil can be increased, thereby effectively preventing soil erosion.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, a cam 209 is fixedly connected to the outer side wall of the output shaft of the driving motor 205 and located in front of the fixing plate 201, and an extrusion box 210 is fixedly connected to the front surface of the fixing plate 201 located in front of the slope protection body 1 and located above the driving motor 205. A piston plate 211 is slidably connected to the inside of the extrusion box 210, and an extrusion rod 212 is fixedly connected to the lower surface of the piston plate 211. The bottom end of the extrusion rod 212 extends to the bottom of the extrusion box 210, and a plurality of springs 219 are fixedly connected to the upper surface of the piston plate 211 and the inner upper surface of the extrusion box 210. A gas delivery hose 213 is fixedly connected to the upper surface of the box 210, a through-type opening slot 214 is provided on the left side of the interior of the spray box 202, and movable chambers 215 are provided inside the spray box 202 and in front and behind the opening slot 214, and a movable plate 216 is provided inside the opening slot 214, and the movable plate 216 is slidably connected to the two movable chambers 215 respectively, and a plurality of atomizing nozzles 217 are provided on the left side of the movable plate 216, and one end of the gas delivery hose 213 away from the squeeze box 210 is fixedly connected to the right side of the interior of the movable chamber 215 located in front of the spray box 202;

[0042] When the driving motor 205 is running, the cam 209 on its output shaft will also rotate accordingly. During the rotation process, the cam 209 periodically pushes the squeezing rod 212 to move upward, thereby driving the piston plate 211 to slide upward in the squeezing box 210, so that the space in the squeezing box 210 can be reduced and the air pressure can be increased. The increased air pressure transmits the gas to the active chamber 215 in the front through the air delivery hose 213, thereby pushing the active plate 216 to move laterally within the range defined by the opening groove 214 and the two active chambers 215, and the movement of the active plate 216 can drive the multiple atomizing nozzles 217 to move laterally. When the cam 209 loses contact with the squeezing rod 212, the piston plate 211 is reset by the rebound of the multiple springs 219, thereby resetting the active plate 216 and the multiple atomizing nozzles 217, which can further increase the efficiency of irrigation and improve the spraying effect and coverage of the device.

[0043] like Figure 3 As shown, a through-type exhaust hole 218 is provided on the inner rear surface of the active chamber 215 located behind the spray box 202;

[0044] When the gas hose 213 delivers gas to the front active chamber 215 to push the active plate 216 to move, the air inside the rear active chamber 215 needs to have an exhaust channel to maintain the air pressure balance inside the front and rear active chambers 215. The exhaust holes 218 are set so that the air in the rear active chamber 215 can be discharged in time, ensuring that the active plate 216 can move horizontally repeatedly and smoothly in the open groove 214, preventing jamming or difficulty in movement due to unbalanced air pressure, and ensuring the stability and reliability of the movement of the active plate 216 and multiple atomizing nozzles 217.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
