Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, and in particular to a watershed ecological restoration and water purification device. Background Technology

[0002] In the process of ecological restoration and water purification, aerators can be used to oxygenate and circulate water bodies such as rivers and lakes. Currently, the aerators are designed as inverted umbrellas. They mainly use the high-speed rotation of their inverted umbrella-shaped impellers to lift and spray water to form a water curtain, thereby achieving aeration, oxygenation and water circulation, which improves dissolved oxygen in the water and inhibits algae growth.

[0003] However, the aforementioned inverted umbrella-shaped aerator still has significant limitations in its use. First, the aerator can only improve the dissolved oxygen in the overlying water, and has little effect on pollutants deposited in the bottom sediment and continuously released. Incomplete treatment can easily lead to repeated deterioration of water quality. Second, during rotation, the inverted umbrella-shaped impeller can only push the water in the current area, resulting in highly turbulent water flow patterns. It is difficult to form an effective directional transport flow field, which limits its ability to act on a large area of ​​water and reduces energy utilization efficiency.

[0004] Therefore, it is necessary to invent a watershed ecological restoration and water purification device to solve the above problems. Summary of the Invention

At high speed, the guide plate base tends to unfold horizontally under the action of centrifugal force, transforming the vertical upward water flow generated by the inverted umbrella-shaped impeller into a strong lateral radiation flow, effectively promoting the water body to carry out long-distance and large-scale horizontal circulation. By expanding the effective range, a single unit can cover a wider water area, reducing the number of equipment and energy consumption required for treatment per unit area, and achieving efficient and economical water purification and ecological restoration at the watershed scale.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Reference Figure 1 - Figure 10 A watershed ecological restoration and water purification device includes a drive component 1. In actual use, a motor that drives the drive component 1 to rotate is installed on the ground above the water area to be restored. The drive component 1 and the drive end of the motor are fixedly connected. An inverted umbrella-shaped impeller 2 is fixedly installed at the bottom end of the drive component 1. A flow guiding component 3 is provided on the surface of the drive component 1. A snap-fit ​​limiting component 4 is provided on the surface of the drive component 1 below the flow guiding component 3. A flow guiding auxiliary component 5 is provided on the surface of the drive component 1. A bottom sediment disturbance component 6 is provided on the bottom surface of the drive component 1. The flow guiding component 3 includes a flow guiding plate base 302 provided on the surface of the drive component 1. A rotatable connecting rod 305 is provided on the surface of the flow guiding plate base 302. A baffle plate 306 is fixedly connected to the surface of the connecting rod 305. A centrifugal slider 31 is slidably connected to the surface of the flow guiding plate base 302. 1. The centrifugal slider 311 is rotatably connected to the driven collar 309 via the connector 308, which is L-shaped. The bottom sediment disturbance component 6 includes a slide rod 61 slidably connected inside the inverted umbrella-shaped impeller 2. The surface of the inverted umbrella-shaped impeller 2 has a through hole, through which the slide rod 61 passes through the upper and lower sides of the inverted umbrella-shaped impeller 2. The top of the slide rod 61 is rotatably connected to the bottom of the guide plate base 302 via the connecting rod 69. The slide rod 61 and the connecting rod 69 are rotatably connected. The bottom surface of the drive component 1 is rotatably connected to the stirring rod 65 via the mounting base 62. In actual use, stirring rods 65 of different lengths can be replaced, or a telescopic stirring rod 65 can be directly used. The telescopic stroke is 20-30cm, and the stirring depth can be flexibly adjusted according to the bottom sediment depth. The mounting base 62 is sleeved on the surface of the drive component 1.

[0024] Reference Figure 4Before use, the larger surface of the baffle 306 is perpendicular to the top surface of the guide plate base 302. At this time, as the guide plate base 302 rotates at low speed with the inverted umbrella impeller 2, the baffle 306 has a large contact area with the water body, thus improving the baffle 306's ability to turbulent the water flow. The strong turbulence promotes the full mixing of oxygen-rich water with bottom sewage and pollutants, enhances the contact efficiency of aerobic microorganisms with pollutants such as organic matter, ammonia nitrogen, and total phosphorus, significantly accelerates the degradation and transformation speed, and shortens the water purification cycle.

[0025] Specifically, when the motor drives the drive component 1 and rotates the inverted umbrella-shaped impeller 2, it achieves efficient oxygenation by forming a mixture of water jump and negative pressure air intake bubbles through centrifugal ejection, thereby increasing dissolved oxygen in the water and accelerating pollutant degradation and sediment remediation. During the rotation of the inverted umbrella-shaped impeller 2, centrifugal force drives the guide plate base 302 to rotate, which in turn drives the connecting rod 305 and the baffle 306 on its surface to rotate. The baffle 306 enhances the turbulence effect on the water body, thus increasing the rate of ecological restoration of the watershed. When the guide plate base 302 rotates under centrifugal force, it pulls the sliding rod 61 through the connecting rod 69. The sliding rod 61 then pulls the stirring rod 65 upwards, which in turn rotates with the drive component 1. This stirring rod 65 agitates the sediment at the bottom of the watershed, accelerating the decomposition of deposited organic matter, reducing sediment thickness, and improving the bottom environment.

[0026] Reference Figure 1 - Figure 5A fixing sleeve 301 is fixedly installed on the surface of the driving component 1. The fixing sleeve 301 is sleeved and fixedly installed on the top surface of the driving component 1. The guide plate base 302 is rotatably connected to the surface of the fixing sleeve 301. The two end faces of the guide plate base 302 are symmetrically chamfered to reduce the resistance when the two end faces rotate and contact the water, thereby reducing the energy consumption of the motor and the wear at the contact point between the guide plate base 302 and the fixing sleeve 301. The guide plate base 302 is provided with four protrusions circumferentially distributed on the surface of the fixing sleeve 301. The top two sides of the guide plate base 302 are fixedly installed with protrusions 303. The protrusions 303 are evenly arrayed on the surface of the guide plate base 302 and are set in a sawtooth shape to sift air in the water. Cutting the air bubbles into smaller ones significantly increases the gas-liquid contact area, thus improving oxygen transfer efficiency. A drive shaft 304 is rotatably connected to the top of the guide plate base 302, and a connecting rod 305 is rotatably connected to the surface of the drive shaft 304. Guide rails 307 are fixedly installed on both sides of the top of the guide plate base 302. The guide rails 307 have internal grooves that slidably connect with connecting parts 308. The connecting parts 308 are slidably connected inside the guide rails 307. The driven collar 309 has a three-fifths arc cross-section and rotatably fits onto the surface of the connecting rod 305. This three-fifths arc cross-section design ensures a tight fit between the driven collar 309 and the connecting rod 305, preventing it from falling off when the connecting rod 305 is pulled to rotate, thus ensuring transmission reliability. The driven collar 309... 9. When moving, the connecting rod 305 can be pulled to move accordingly, thereby driving the connecting rod 305 to rotate. Sliding grooves 310 are provided on both sides of the top of the guide plate base 302. The centrifugal slider 311 is slidably connected inside the sliding groove 310. A return spring 312 is fixedly installed on the end face of the centrifugal slider 311, and the other end of the return spring 312 is fixedly installed on the inner wall of the sliding groove 310. A guide rod is installed inside the sliding groove 310, and the centrifugal slider 311 is slidably connected to the surface of the guide rod to ensure the stability of the centrifugal slider 311 during sliding and to ensure that the sliding direction of the centrifugal slider 311 does not change. A gear 313 is fixedly installed on the surface of the connecting rod 305, and a rack 31 is fixedly installed on the top of the guide plate base 302. 4. When the connecting rod 305 rotates towards the top of the guide plate base 302, the connecting rod 305 will also drive the gear 313 to rotate. The rack 314 and the gear 313 are meshed. At this time, the gear 313 will rotate under the meshing action of the rack 314. Since the rotation amplitude of the connecting rod 305 is small, the gear 313 and the rack 314 will not jam. The top of the guide plate base 302 is rotatably connected to the stabilizing sleeve 315. The stabilizing sleeve 315 is composed of a telescopic straight rod and a stabilizing sleeve. The telescopic straight rod is rotatably connected to the top of the guide plate base 302 and the top end is fixedly connected to the stabilizing sleeve. The stabilizing sleeve is slidably connected to the surface of the connecting rod 305. The stabilizing sleeve 315 can support and stabilize the rotating connecting rod 305.

[0027] Specifically, during the process of the operator driving the drive component 1 to rotate the fixed sleeve 301, the guide plate base 302 rotatably connected to the surface of the fixed sleeve 301 also rotates with the fixed sleeve 301. When the initial speed is low, the guide plate base 302 is in a vertical state close to the drive component 1, and at this time, the baffle plate 306 has a large contact area with the water body when it rotates with the guide plate base 302. That is, at this time, the baffle plate 306 has a strong turbulence effect on the water body, improving the watershed repair efficiency of the low-speed drive component 1 and the inverted umbrella impeller 2. As the rotational speed of the driving component 1 gradually increases, the centrifugal force on the guide plate base 302 also gradually increases. This means the guide plate base 302 will gradually approach a horizontal state. At this time, the centrifugal slider 311 will also move away from the driving component 1 within the sliding groove 310 under the action of centrifugal force. During this movement, the centrifugal slider 311 will cause the connecting member 308 to slide within the guide rail 307. The movement of the connecting member 308 will then cause the driven collar 309 to move accordingly. Since the connecting rod 305 is initially in an inclined state, it gradually moves away from the guide plate base 302 away from the drive shaft 304. Simultaneously, since the length of the connecting member 308 is fixed, as the connecting member 308 and the driven collar 309 continue to move, they will pull the connecting rod 305 away from the drive shaft 304 and gradually closer to the guide plate base 302. That is, at this time, the connecting rod... 305 drives the drive shaft 304 to rotate on the surface of the guide plate base 302, and the end of the connecting rod 305 away from the drive shaft 304 is always supported by the stabilizing sleeve 315 to maintain the stability of the connecting rod 305 during rotation. At the same time, as the connecting rod 305 approaches the guide plate base 302, it drives the gear 313 to move accordingly. At this time, the gear 313 rotates under the meshing action of the rack 314. Simultaneously, the gear 313 drives the baffle 306 to rotate through the connecting rod 305. At this time, the rotation speed of the guide plate base 302 also gradually increases. When the guide plate base 302 rotates to a state close to horizontal, until the baffle 306 rotates to a state parallel to the top of the guide plate base 302, the baffle 306 after rotation reduces the contact area with the water, thereby avoiding the possibility of damage to the baffle 306 due to large water resistance when the rotation speed of the guide plate base 302 is relatively fast.

[0028] Reference Figure 5 - Figure 6The locking and limiting assembly 4 includes a positioning frame 41 fixedly installed on the surface of the driving component 1. A slot 42 is provided on the side of the positioning frame 41 away from the driving component 1. The guide plate base 302 is locked inside the slot 42. A buffer spring 43 is fixedly installed in the middle of the slot 42. The buffer spring 43 is made of stainless steel. A weakening part is provided at the bend of the buffer spring 43 so that the buffer spring 43 can buffer and support the support rod 44. The other end of the buffer spring 43 is fixedly installed with the support rod 44. The guide plate base 302 and the support rod 44 are adapted to each other and make contact. A stabilizing telescopic rod 45 is rotatably connected to the top of the positioning frame 41. A positioning pin 46 is fixedly installed at the other end of the stabilizing telescopic rod 45. A positioning groove 47 is provided at the bottom of the guide plate base 302. The positioning pin 46 is slidably connected inside the positioning groove 47. The stabilizing telescopic rod 45 and the positioning pin 46 can support the guide plate base 302.

[0029] Specifically, before the drive component 1 rotates, the guide plate base 302 is engaged inside the slot 42. During the rotation of the drive component 1, as the guide plate base 302 approaches a horizontal state, the stabilizing telescopic rod 45 can rotate, allowing the positioning pin 46 to always slide inside the positioning groove 47. At this time, the stabilizing telescopic rod 45 and the positioning pin 46 always support the rotating guide plate base 302, ensuring the stability of the guide plate base 302 during rotation. After the drive component 1 rotates, the guide plate base 302 will rotate downwards under the action of gravity. At this time, the buffer spring 43 and the support rod 44 can provide buffer support for the downward rotating guide plate base 302.

[0030] Reference Figure 7 The flow guiding auxiliary component 5 includes a flow guiding auxiliary plate 51 fixedly installed on the surface of the fixed sleeve 301. The flow guiding auxiliary plate 51 and the flow guiding plate base 302 are arranged alternately. A support column 52 is fixedly installed at the bottom end of the fixed sleeve 301. A support rod 53 is fixedly installed on the surface of the support column 52. The end of the support rod 53 away from the support column 52 is fixedly installed at the bottom end of the flow guiding auxiliary plate 51 to provide stable support for the flow guiding auxiliary plate 51. A flow guiding hole 54 is opened on the surface of the flow guiding auxiliary plate 51. Inclined plates 55 are symmetrically fixedly installed on both sides of the flow guiding auxiliary plate 51. The two inclined plates 55 are rounded on the side away from each other to reduce water flow resistance.

[0031] Specifically, during the rotation of the fixed sleeve 301, the flow-guiding auxiliary plates 51, which are set in the gaps between the bases 302 of each flow guide plate, will rotate accordingly. At this time, the combination of the support column 52 and the support rod 53 maintains the stability of the flow-guiding auxiliary plate 51 during rotation. The rounded corners of the inclined plate 55 reduce the resistance encountered by the flow-guiding auxiliary plate 51 during rotation. Since the flow-guiding holes 54 are opened on the surface of the flow-guiding auxiliary plate 51, the high-pressure zone and the low-pressure zone are connected in the horizontal direction, which optimizes the gas-liquid mixing efficiency and stabilizes the flow field. In the vertical direction, a channel is provided for the exchange between the upper and lower layers of water, which enhances the three-dimensional circulation effect.

[0032] Reference Figure 6 - Figure 10 The mounting base 62 is fixedly installed on the bottom surface of the drive component 1. A support rod 63 is fixedly connected to the top of the surface of the mounting base 62. A support sleeve 64 is fixedly connected to the other end of the support rod 63. The support sleeve 64 can support the slide rod 61 to make it stable. The slide rod 61 is slidably connected inside the support sleeve 64. A telescopic support 66 is provided on the surface of the stirring rod 65. The telescopic support 66 is composed of a telescopic rod and an upper sliding sleeve and a lower sliding sleeve that are rotatably connected to its upper and lower ends respectively. The upper sliding sleeve is fixedly installed on the surface of the support rod 63. The lower sliding sleeve is slidably connected to the surface of the stirring rod 65. The telescopic support 66 can further provide stable support for the stirring rod 65. A groove is opened at the top of the stirring rod 65 and slidably connected to the bottom end of the slide rod 61. An elastic element 67 is fixedly installed at the bottom end of the support rod 63 near the mounting base 62. A protective pad 68 is fixedly installed at the bottom end of the elastic element 67. The top of the stirring rod 65 and the bottom of the protective pad 68 are adapted to contact each other.

[0033] Specifically, when the guide plate base 302 is running and rotating to a horizontal position, it will drive the connecting rod 69 at the bottom to move upward. At the same time, the connecting rod 69 will drive the sliding rod 61 to move upward. At this time, the combination of the support rod 63 and the support sleeve 64 can stably support the sliding rod 61 that rotates with the drive component 1. At this time, the bottom of the sliding rod 61 slides inside the top of the stirring rod 65. Therefore, the upward movement of the sliding rod 61 will pull the stirring rod 65 to rotate. At this time, the elastic element 67 and the protective pad 68 will buffer the top of the stirring rod 65 under the action of elasticity, so that the stirring rod 65 rotates to an angle of about 45 degrees with the horizontal direction. At this time, the telescopic support 66 can also stably support the stirring rod 65 that rotates with the drive component 1. The rotating stirring rod 65 can stir the bottom sediment of the watershed. Through physical stirring, the bottom sediment pollutants are suspended to the oxygen-rich water layer, thereby expanding the single oxygenation function of the equipment to an integrated and synergistic treatment of water and bottom sediment endogenous pollution, thus solving the problem of continuous release of pollutants.

[0034] In this invention, when the motor drives the drive component 1 and drives the inverted umbrella-shaped impeller 2 to rotate, the centrifugal ejection forms a mixture of water jump and negative pressure air intake bubbles to achieve efficient oxygenation, thereby increasing the dissolved oxygen in the water and accelerating the degradation of pollutants and the remediation of bottom sediment.

[0035] During the process of driving the drive component 1 to rotate the fixed sleeve 301, the guide plate base 302 rotatably connected to the surface of the fixed sleeve 301 also rotates with the fixed sleeve 301. When the initial speed is low, the guide plate base 302 is in a vertical state close to the drive component 1. At this time, the baffle plate 306 has a large contact area with the water body when it rotates with the guide plate base 302. That is, the baffle plate 306 has a strong turbulence effect on the water body, which improves the watershed repair efficiency of the low-speed drive component 1 and the inverted umbrella impeller 2. As the rotational speed of the driving component 1 gradually increases, the centrifugal force on the guide plate base 302 also gradually increases. This means the guide plate base 302 will gradually approach a horizontal state. At this time, the centrifugal slider 311 will also move away from the driving component 1 within the sliding groove 310 under the action of centrifugal force. During this movement, the centrifugal slider 311 will cause the connecting member 308 to slide within the guide rail 307. The movement of the connecting member 308 will then cause the driven collar 309 to move accordingly. Since the connecting rod 305 is initially in an inclined state, it gradually moves away from the guide plate base 302 away from the drive shaft 304. Simultaneously, since the length of the connecting member 308 is fixed, as the connecting member 308 and the driven collar 309 continue to move, they will pull the connecting rod 305 away from the drive shaft 304 and gradually closer to the guide plate base 302. That is, at this time, the connecting rod... 305 drives the drive shaft 304 to rotate on the surface of the guide plate base 302, and the end of the connecting rod 305 away from the drive shaft 304 is always supported by the stabilizing sleeve 315 to maintain the stability of the connecting rod 305 during rotation. At the same time, as the connecting rod 305 approaches the guide plate base 302, it drives the gear 313 to move accordingly. At this time, the gear 313 rotates under the meshing action of the rack 314. Simultaneously, the gear 313 drives the baffle 306 to rotate through the connecting rod 305. At this time, the rotation speed of the guide plate base 302 also gradually increases. When the guide plate base 302 rotates to a state close to horizontal, until the baffle 306 rotates to a state parallel to the top of the guide plate base 302, the baffle 306 after rotation reduces the contact area with the water, thereby avoiding the possibility of damage to the baffle 306 due to large water resistance when the rotation speed of the guide plate base 302 is relatively fast.

[0036] Before the drive component 1 rotates, the guide plate base 302 is engaged inside the slot 42. During the rotation of the drive component 1, as the guide plate base 302 approaches a horizontal state, the stabilizing telescopic rod 45 can rotate and always slides inside the positioning pin 46. At this time, the stabilizing telescopic rod 45 and the positioning pin 46 always support the rotating guide plate base 302, ensuring the stability of the guide plate base 302 during rotation. After the drive component 1 rotates, the guide plate base 302 will rotate downward under the action of gravity. At this time, the buffer spring 43 and the support rod 44 can provide buffer support for the downward rotating guide plate base 302.

[0037] Meanwhile, as the fixed sleeve 301 rotates, the flow-guiding auxiliary plates 51, which are set in the gaps between the bases 302 of each flow guide plate, will rotate accordingly. At this time, the combination of the support column 52 and the support rod 53 maintains the stability of the flow-guiding auxiliary plate 51 during rotation. The rounded corners of the inclined plate 55 reduce the resistance encountered by the flow-guiding auxiliary plate 51 during rotation. Since the flow-guiding holes 54 are opened on the surface of the flow-guiding auxiliary plate 51, the high-pressure zone and the low-pressure zone are connected in the horizontal direction, which optimizes the gas-liquid mixing efficiency and stabilizes the flow field. In the vertical direction, a channel is provided for the exchange between the upper and lower layers of water, which enhances the three-dimensional circulation effect.

[0038] When the guide plate base 302 is running and rotating to a horizontal position, it will drive the connecting rod 69 at the bottom to move upward. At the same time, the connecting rod 69 will drive the sliding rod 61 to move upward. At this time, the combination of the support rod 63 and the support sleeve 64 can stably support the sliding rod 61 that rotates with the drive component 1. At this time, the bottom of the sliding rod 61 slides inside the top of the stirring rod 65. Therefore, the upward movement of the sliding rod 61 will pull the stirring rod 65 to rotate. At this time, the elastic element 67 and the protective pad 68 will buffer the top of the stirring rod 65 under the action of elasticity, so that the stirring rod 65 rotates to an angle of about 45 degrees with the horizontal direction. At this time, the telescopic support 66 can also stably support the stirring rod 65 that rotates with the drive component 1. The rotating stirring rod 65 can stir the bottom sediment of the watershed. Through physical stirring, the bottom sediment pollutants are suspended to the oxygen-rich water layer, thereby expanding the single oxygenation function of the equipment to an integrated and synergistic treatment of water and bottom sediment endogenous pollution, thus solving the problem of continuous release of pollutants.
