Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river ecological restoration, and in particular to a river ecological restoration device and method. BACKGROUND

[0002] River ecological restoration is a systematic project based on the principle of ecological system, and its core goal is to restore the damaged water body ecological system. Specifically, it is to restore the damaged biological population and its structure, and to rebuild a healthy and stable aquatic ecological system. This process not only restores and strengthens the key functions of the water body ecological system, such as material circulation, energy flow and information transmission, but also makes the entire ecological system achieve a benign cycle state of overall coordination, self-maintenance and self-succession. Through river ecological restoration, the self-purification capacity of the water body can be effectively improved, the water quality can be improved, and a suitable living environment can be provided for aquatic organisms, thereby maintaining biodiversity and ensuring the stability and sustainable development of the ecological system.

[0003] In traditional river ecological restoration practice, interception devices and desilting equipment are often used to improve the internal environment of the river. Interception devices such as floating balls and trash screens are widely used to intercept garbage floating on the water surface to prevent further spread and pollution of the water body. Desilting equipment is mainly used to treat the silt deposited at the river bottom. By extracting and cleaning the silt, the release of pollutants in the silt is reduced, and the negative impact on water quality is avoided. These methods can effectively improve the river environment to some extent, reduce the harm of harmful substances in the garbage degradation process to aquatic animals, and protect the survival and reproduction of aquatic organisms. It is of great significance to maintain the health of the river ecological system.

[0004] However, the traditional river ecological restoration method also has some obvious limitations. On the one hand, although the interception devices such as floating balls and trash screens can intercept garbage, subsequent manual salvage is required, which not only increases the labor cost, but also has relatively low efficiency. Especially in the case of large amount of garbage or complex river conditions, salvage work is often time-consuming and labor-intensive, which seriously affects the speed and effect of river ecological restoration. On the other hand, the desilting equipment usually needs external power support during use, which increases energy consumption and operating cost. SUMMARY

[0022] Compared with the prior art, the river ecological restoration device and method have the following beneficial effects:

[0023] 1.

[0024] 2. The river ecological restoration device, through the setting of the conveying part, when the water turbine rotates under the impact of the water flow, the auger rod and the spiral blade can rotate, the spiral blade and the auger rod can cooperate with each other to transport and extract the garbage in the inner cavity of the pollution guide shell, thereby improving the cleaning quality and efficiency of the water surface garbage, and when the desilting part separates the silt and the water flow, the water flow returning to the river will impact the windmill wheel downward, so that the windmill wheel rotates to drive the brush plate to move on the surface of the filter plate to clean the filter plate;

[0054] Specifically, after the river sluice is opened, the upstream water flow quickly passes through the river sluice, and the impact force of the water flow also moves the silt at the bottom of the river. At this time, the silt can be intercepted by the setting of the stone cage 3. When the staff needs to extract and process the silt, the external control switch is used to start the mud pumping pump 45. The mud pumping pump 45 extracts the silt and discharges it into the inner cavity of the flow guide seat 49. The second filter screen 410 is used to filter the silt and water flow, and the flow guide seat 49 is provided with two guide surfaces, one for guiding the discharge of silt, and the other for guiding the discharge of water flow.

The second sleeve 72 is rotatably connected with a generator 73 fixedly connected to the protection frame 7.

[0058] Specifically, when the river sluice is opened, the impact of the water flow will drive the water turbine 6 to rotate.

[0061] The conveying part comprises: at least two flow guide shells 8 fixedly connected to the bottom of the pollution guide shell 10 and communicating with the inner cavity of the pollution guide shell 10, wherein the two flow guide shells 8 are fixedly connected with a lifting cylinder 81 away from one side of the pollution guide shell 10, the two lifting cylinders 81 are fixedly connected with a discharge frame 82, and the two lifting cylinders 81 are rotatably connected with an auger rod 83; a first sprocket 84 fixedly sleeved on the auger rod 83, wherein the first sprocket 84 is drivingly connected with a second sprocket 85 through a chain, and the second sprocket 85 is fixedly connected with the output shaft of the water turbine 6; a third bevel gear 86 fixedly connected to the bottom of one of the auger rods 83, wherein the third bevel gear 86 is meshingly connected with a fourth bevel gear 87, the fourth bevel gear 87 is fixedly connected with a third synchronous wheel 88 away from one end of the third bevel gear 86, and the third synchronous wheel 88 is rotatably connected with a protective cover 89 fixedly connected with the lifting cylinder 81 away from one end of the third bevel gear 86; a positioning rod 810 rotatably connected in the pollution guide shell 10, wherein the positioning rod 810 is fixedly sleeved with at least two spiral blades 811, the two spiral blades 811 are oppositely arranged, one end of the positioning rod 810 penetrates through the protective cover 89 and is fixedly connected with a fourth synchronous wheel 812 drivingly connected with the third synchronous wheel 88; a limiting frame 813 fixedly connected to the filter plate 11, wherein the limiting frame 813 is rotatably connected with a second reciprocating screw rod 814, the second reciprocating screw rod 814 is slidingly sleeved with a second nut sliding sleeve 815, and the second nut sliding sleeve 815 is fixedly connected with a brush plate 816 in contact with the filter plate 11; a windmill wheel 817 fixedly connected to one end of the second reciprocating screw rod 814, and the windmill wheel 817 is located below one of the guiding faces of the flow guide seat 49.

[0062] Specifically, under the buoyancy support of the floating plate 5, the pollution guide shell 10 and the filter plate 11 can float on the water surface, and the pollution guide shell 10 is arranged below the floating plate 5, so that the top of the pollution guide shell 10 is flush with the water surface. Under the impact of the water flow, the garbage floating on the water surface will be drifted to the pollution guide shell 10 and the filter plate 11 through the guide groove at the bottom of the floating plate 5. By cooperating the pollution guide shell 10 and the filter plate 11, the garbage can be intercepted. In the rotating process of the water turbine 6, the second sprocket 85 can be rotated, the chain is driven to rotate when the second sprocket 85 rotates, the first sprocket 84 is driven to rotate when the chain is driven to rotate, the auger rod 83 is driven to rotate when the first sprocket 84 rotates, the third bevel gear 86 is driven to rotate when the auger rod 83 rotates, the fourth bevel gear 87 is driven to rotate when the third bevel gear 86 rotates, the third synchronous wheel 88 is driven to rotate when the fourth bevel gear 87 rotates, the belt is driven to rotate when the third synchronous wheel 88 rotates, the fourth synchronous wheel 812 is driven to rotate when the belt is driven to rotate, the positioning rod 810 is driven to rotate when the fourth synchronous wheel 812 rotates, and the two helical blades 811 on the surface of the positioning rod 810 are rotated, so as to transport the garbage in the inner cavity of the pollution guide shell 10 to both ends. After the garbage is transported to the specified position, it will enter the lifting cylinder 81 through the flow guide shell 8, and then the garbage is upwardly transported by the auger rod 83, so that the garbage can be concentratedly discharged, which is convenient for subsequent cleaning by the staff.

[0063] After the silt part filters and guides the silt and water flow, the water flow flows downward into the river channel. The windmill wheel 817 is arranged at the lower end of the backflow water flow. When the water flow impacts on the windmill wheel 817, the windmill wheel 817 rotates and drives the second reciprocating screw rod 814 to rotate. The second screw nut sliding sleeve 815 is moved when the second reciprocating screw rod 814 rotates, and the brush plate 816 is reciprocated on the surface of the filter plate 11 when the second screw nut sliding sleeve 815 moves, so as to clean the adhered garbage and avoid the blockage of the filter plate 11, which affects the water flow discharge.

[0064] Example five:

[0065] Reference Figures 1-6 The embodiment is basically the same as the first embodiment, and preferably, the specific implementation scheme of self-adaptive adjustment of the floating plate 5 is specifically implemented.

[0066] The concrete structure 1 is provided with an adaptive adjusting part, the adaptive adjusting part is used for assisting supporting the floating plate 5, and the adaptive adjusting part comprises a box body 9 fixedly installed on the concrete structure 1, wherein a winding roller 91 is rotatably connected in the box body 9, a steel cable 92 is sleeved on the winding roller 91, and one end of the steel cable 92 away from the winding roller 91 is fixedly connected with the floating plate 5; a guide wheel 93 is rotatably connected in the box body 9, wherein the guide wheel 93 is in contact with the steel cable 92, a torsional spring 94 is arranged in the box body 9, and two ends of the torsional spring 94 are fixedly connected with the box body 9 and the winding roller 91 respectively; a first limiting frame is fixedly connected on the concrete structure 1, and a first limiting column fixedly connected with the floating plate 5 is slidably connected in the first limiting frame.

[0067] Specifically, since the concrete structure 1 is arranged near the river gate, the height of water flow before and after discharge is different, when the water level gradually decreases, the weight of the pollution guide shell 10, the filter plate 11 and the like connected with the floating plate 5 will promote the floating plate 5 to move downward along with the water level, and when the floating plate 5 moves downward, one end of the steel cable 92 is pulled to move downward, at this time, the other end of the steel cable 92 drives the winding roller 91 to rotate, the torsional spring 94 is extruded, the force of the torsional spring 94 is smaller than the gravity of the part connected with the floating plate 5, when the water level rises, the buoyancy of the floating plate 5 will drive the pollution guide shell 10, the filter plate 11 and the like to move upward, at this time, the reaction force of the torsional spring 94 can drive the winding roller 91 to rotate, the steel cable 92 is tightened, and the stability of the use of the floating plate 5 is improved.
