The aerator comprises an aerator, wherein a threaded tube is connected through the bottom of the aerator, and a rotating tube is rotatably connected to the top of the aerator. Before use, when high-pressure gas is ejected outward through the aerator, upward high-pressure bubbles will provide a lateral force for the fan blades, forcing five fan blades to drive the rotating tube to rotate.

Technical Field

[0001] The invention relates to the technical field of aeration equipment for water treatment, in particular to an aeration device for water treatment and a use method thereof. Background Art

[0002] During sewage treatment, sewage is usually discharged into an aeration tank, and air is introduced into the sewage through an aeration device to dissolve oxygen or disperse dissolved gases and volatile substances in the water. At the same time, it makes it difficult for suspended matter in the tank to sink, strengthens the contact between organic matter and dissolved oxygen, and facilitates the oxidation and decomposition of organic matter in the sewage.

[0003] Among them, when the aeration device is running in the sewage pool, the gas forms a dense bubble column through the aeration device and floats upward to realize the aeration process. When the aeration device generates bubbles, the liquid around the aeration device is pressurized and diffuses to the surroundings, resulting in a corresponding reduction in the contact volume between the gas and the liquid, causing insufficient aeration of the wastewater. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an aeration device for water treatment, comprising an aerator, wherein a threaded pipe is connected through the bottom of the aerator, and a rotating pipe is rotatably connected to the top of the aerator;

[0005] A stirring mechanism, the stirring mechanism includes a fan blade for changing the direction of the external water flow, a fixing bracket, a fixing plate, an arc plate, and a cleaning mechanism for cleaning the fan blade;

[0006] The side wall of the rotating tube is fixedly connected to the side wall of the fan blade, the end of the fan blade away from the rotating tube is fixedly connected to the side wall of the fixed bracket, the end of the fixed bracket away from the fan blade is fixedly connected to the side wall of the fixed plate, and the side wall of the fixed plate is fixedly connected to the side wall of the arc plate. Before use, the device is connected to the external high-pressure air pipe through a threaded pipe. When the high-pressure gas is ejected outward through the aerator, the high-pressure air column generated by the aerator will contact the inclined fan blades, and the upward high-pressure bubbles will provide a lateral force for the fan blades, forcing the five fan blades to drive the rotating tube to rotate. The rotating fan blades drive the arc plate to rotate synchronously through the fixed bracket and the fixed plate. During this process, the rotating arc plate contacts the wastewater outside the bubble column, forcing the external wastewater to approach the rotating tube along the arc surface of the arc plate. The arc plate is large at one end and small at the other end. When the wastewater enters from the large mouth and flows out to the small hole along the outer wall of the arc plate, the water flow rate out of the arc plate will be increased. Through the application of the above components, when the equipment is running, the water flow outside the bubble column can increase the contact area between the liquid and the bubbles through the application of the arc plate, thereby improving the aeration efficiency.

[0007] Preferably, the cleaning mechanism includes a scratch frame slidably connected to the outer walls of the five fan blades, the side walls of the scratch frame are rotatably connected to a support rod, the outer wall of the support rod is fixedly connected to an inclined plate, the side wall of the inclined plate is fixedly connected to a scratch assembly, and the side wall of the scratch frame is fixedly connected to a control assembly. Utilizing the above-mentioned characteristics of the rotation of the fan blades, a cleaning mechanism is arranged inside the device. When the fan blades rotate due to high-pressure bubbles, the inclined plate also contacts with the external wastewater, which presents a Figure 4 When the fan blade rotates clockwise due to the high-pressure bubbles, the external liquid will also contact the left side of the inclined plate. At this time, the inclined plate will be pushed by the water flow and will drive the scratch frame to move horizontally to the right along the outer wall of the fan blade through the support rod. At this time, as the scratch frame moves horizontally, the side wall of the inclined plate will contact one end of the spring telescopic rod 1, and as the inclined plate moves outward, the spring telescopic rod 1 is compressed and deformed.

[0008] Preferably, the cleaning mechanism also includes a spring telescopic rod fixedly connected to the side wall of the fan blade, an inclined panel fixedly connected to the side wall of the fan blade, and two sliding frames fixedly connected to the top of the scratch frame.

[0010] Preferably, the cleaning mechanism also includes an inclined hook plate fixedly connected to both ends of the support rod, an inclined panel 2 is fixedly connected to the side wall of the fan blade, and a spring telescopic rod 2 is fixedly connected to the side wall of the fan blade. As the support rod moves outward, the side wall of the roller will contact the inclined surface of the inclined panel 1, presenting a Figure 5 The L-shaped plate is in a state of being in a state of being in a state, and at this time the roller moves outwards along the inner wall of the sliding frame through the L-shaped slide plate, so that one end of the L-shaped slide plate is away from the outer wall of the inclined hook plate, and the L-shaped slide plate releases the restriction on the inclined hook plate and the inclined plate, and at this time the inclined plate plate will release the mechanical power, so that the inclined plate and the support rod will swing around the connection point as the center, so that the inclined plate drives the inclined hook plate at the other end to insert into the L-shaped slide plate at the other end, so that the inclined plate will no longer swing after completing the swing. Through the application of the above components, the scratch frame can clean the outer wall of the fan blade for a long time when the equipment is running, so as to avoid the accumulation of impurities on the outer wall of the fan blade, which will affect the efficiency of the arc plate in guiding water flow.

[0011] Preferably, the scraping assembly includes two slide grooves opened on the side walls of the inclined plate, a sliding scraper 1 is slidably connected to the inner wall of one slide groove, a spring 2 is fixedly connected to the side wall of the sliding scraper 1, and the end of the spring 2 away from the sliding scraper 1 is fixedly connected to the inner wall of the slide groove. By utilizing the characteristic that the above-mentioned scraping frame slides along the outer wall of the fan blade, a scraping assembly is arranged inside the device. When the inclined plate moves due to external water flow, the external water flow will also flow along the outer wall of the inclined plate, presenting a Figure 7 When the external water flows from bottom to top, the water will contact the outer wall of the sliding scraper plate 1, forcing the sliding scraper plate 1 to slide outward along the inner wall of the slide groove and squeeze the spring 2, so that the spring 2 accumulates mechanical power.

[0012] Preferably, the scraping assembly also includes a sliding scraper 2 slidably connected to the inner wall of another slide groove, and a spring 3 is fixedly connected to the side wall of the sliding scraper 2, and the end of the spring 3 away from the sliding scraper 2 is fixedly connected to the inner wall of the slide groove. When the inclined plate reaches the edge and swings, the contact surface between the inclined plate and the wastewater will change, and the side of the inclined plate close to the sliding scraper 2 will directly contact the external wastewater, forcing the sliding scraper 2 to slide along the inner wall of the slide groove, while the side of the inclined plate close to the sliding scraper 1 is on the back of the water. At this time, the pressure on the sliding scraper 1 is reduced, and the sliding scraper 1 slides outward along the inner wall of the slide groove under the push of the spring 2 to remove most of the impurities on the outer wall of the inclined plate. Through the application of the above-mentioned components, the impurities on the outer wall of the inclined plate can be removed, and the impurities in the wastewater can be prevented from accumulating on the outer wall of the inclined plate and affecting the turning speed of the inclined plate.

[0013] Preferably, the control component includes five hydraulic telescopic rods connected through the side wall of the rotating tube, one end of the five hydraulic telescopic rods away from the rotating tube is fixedly connected to the outer wall of the scratch frame, and one end of the hydraulic telescopic rods away from the scratch frame is connected through an L-shaped tube.

By utilizing the characteristics of the above-mentioned multiple inclined plates driving the corresponding scratch frames to slide, a control component is arranged inside the equipment. When the scratch frame moves outward, the hydraulic telescopic rod is pulled, so that the hydraulic telescopic rod draws liquid inside the hydraulic tube through the L-shaped tube, forcing the piston plate to slide upward along the inner wall of the hydraulic tube, and in this process, the multiple piston plates drive the fixing rings to slide upward through the corresponding fixing rods, presenting a Figure 8During this process, the fixed ring will limit the speed and height of the multiple piston plates moving up, and indirectly control the length and speed of the multiple hydraulic telescopic rods extending outward. Through the application of the above components, the speed and length of the scratch frame moving outward are guaranteed to be equal, avoiding unequal pressure on each blade and affecting the rotation speed of the blade.

[0015] A method for using an aeration device for water treatment comprises the following steps:

[0016] S1: Install the equipment: Before use, connect the equipment with the external high-pressure gas pipe through the threaded pipe;

[0017] S2: When high-pressure gas is ejected outward through the aerator, the high-pressure gas column generated by the aerator will come into contact with the inclined blades, and the upward high-pressure bubbles will provide a lateral force for the blades, forcing the five blades to drive the rotating tube to rotate.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that the bottom high-pressure gas is ejected upward during aeration. Fan blades and arc plates are arranged inside the device. Before use, the device is connected to the external high-pressure gas pipe through a threaded pipe. When the high-pressure gas is ejected outward through the aerator, the high-pressure gas column generated by the aerator will contact the inclined fan blades. The upward high-pressure bubbles will provide a lateral force for the fan blades, forcing the five fan blades to drive the rotating tube to rotate. The rotating fan blades drive the arc plate to rotate synchronously through the fixed bracket and the fixed plate. During this process, the rotating arc plate contacts the wastewater outside the bubble column, forcing the external wastewater to approach the rotating tube along the arc surface of the arc plate, and the arc plate is large at one end and small at the other end. When the wastewater enters from the large mouth and flows out along the outer wall of the arc plate to the small hole, the water flow velocity flowing out of the arc plate will be increased. Through the application of the above components, when the device is running, the water flow outside the bubble column can pass through the application of the arc plate, thereby increasing the contact surface between the liquid and the bubbles and improving the aeration efficiency.

[0020] (2) The present invention utilizes the above-mentioned characteristic of blade rotation and sets a cleaning mechanism inside the device. When the blade rotates due to high-pressure bubbles, the inclined plate also contacts the external wastewater, which presents the following Figure 4 When the fan blade rotates clockwise due to the high-pressure bubbles, the external liquid will also contact the left side of the inclined plate. At this time, the inclined plate will be pushed by the water flow and will drive the scratch frame to move horizontally to the right along the outer wall of the fan blade through the support rod. At this time, as the scratch frame moves horizontally, the side wall of the inclined plate will contact one end of the spring telescopic rod 1, and as the inclined plate moves outward, the spring telescopic rod 1 is compressed and deformed. Finally, as the support rod moves outward, the side wall of the roller will contact the inclined surface of the inclined panel 1, presenting a situation as shown in the figure. Figure 5The L-shaped plate is in a state of being in a state of being in a state, and at this time the roller moves outwards along the inner wall of the sliding frame through the L-shaped slide plate, so that one end of the L-shaped slide plate is away from the outer wall of the inclined hook plate, and the L-shaped slide plate releases the restriction on the inclined hook plate and the inclined plate, and at this time the inclined plate plate will release the mechanical power, so that the inclined plate and the support rod will swing around the connection point as the center, so that the inclined plate drives the inclined hook plate at the other end to insert into the L-shaped slide plate at the other end, so that the inclined plate will no longer swing after completing the swing. Through the application of the above components, the scratch frame can clean the outer wall of the fan blade for a long time when the equipment is running, so as to avoid the accumulation of impurities on the outer wall of the fan blade, which will affect the efficiency of the arc plate in guiding water flow.

[0021] (3) The present invention utilizes the characteristic that the scratch frame slides along the outer wall of the fan blade, and a scratch component is arranged inside the device. When the inclined plate moves due to the external water flow, the external water flow will also flow along the outer wall of the inclined plate, presenting a Figure 7 When the external water flows from bottom to top, the water will contact the outer wall of the sliding scraper plate 1, forcing the sliding scraper plate 1 to slide outward along the inner wall of the chute and squeeze the spring 2, so that the spring 2 accumulates mechanical power; when the inclined plate reaches the edge and swings, the contact surface between the inclined plate and the wastewater will change, and the side of the inclined plate close to the sliding scraper plate 2 will directly contact the external wastewater, forcing the sliding scraper plate 2 to slide along the inner wall of the chute, while the side of the inclined plate close to the sliding scraper plate 1 is on the back of the water. At this time, the pressure on the sliding scraper plate 1 is reduced, and the sliding scraper plate 1 slides outward along the inner wall of the chute under the push of the spring 2, removing most of the impurities on the outer wall of the inclined plate. Through the application of the above components, the impurities on the outer wall of the inclined plate are removed, and the impurities in the wastewater are prevented from accumulating on the outer wall of the inclined plate, affecting the turning speed of the inclined plate.

[0022] (4) The present invention utilizes the characteristic that the above-mentioned multiple inclined plates drive the corresponding scratch frames to slide. A control component is arranged inside the device. When the scratch frame moves outward, the hydraulic telescopic rod is pulled, so that the hydraulic telescopic rod extracts the liquid inside the hydraulic pipe through the L-shaped pipe, forcing the piston plate to slide upward along the inner wall of the hydraulic pipe. In this process, the multiple piston plates drive the fixed ring to slide upward through the corresponding fixed rod, presenting a Figure 8 During this process, the fixed ring will limit the speed and height of the multiple piston plates moving up, and indirectly control the length and speed of the multiple hydraulic telescopic rods extending outward. Through the application of the above components, the speed and length of the scratch frame moving outward are guaranteed to be equal, avoiding unequal pressure on each blade and affecting the rotation speed of the blade.

[0037] The stirring mechanism 2 includes a fan blade 21 for changing the direction of the external water flow, a fixing bracket 22, a fixing plate 23, an arc plate 24, and a cleaning mechanism 3 for cleaning the fan blade 21;

[0038] The side wall of the rotating tube 12 is fixedly connected to the side wall of the fan blade 21, the end of the fan blade 21 away from the rotating tube 12 is fixedly connected to the side wall of the fixed bracket 22, the end of the fixed bracket 22 away from the fan blade 21 is fixedly connected to the side wall of the fixed plate 23, and the side wall of the fixed plate 23 is fixedly connected to the side wall of the arc plate 24. Before use, the device is connected to the external high-pressure gas pipe through the threaded tube 11. When the high-pressure gas is ejected outward through the aerator 1, the high-pressure gas column generated by the aerator 1 will contact the inclined fan blade 21, and the upward high-pressure bubbles will provide a lateral force for the fan blade 21, forcing the five fan blades 21 to drive the rotating tube 12 into The rotating fan blades 21 drive the arc plate 24 to rotate synchronously through the fixed bracket 22 and the fixed plate 23. During this process, the rotating arc plate 24 contacts the wastewater outside the bubble column, forcing the external wastewater to approach the rotating tube 12 along the arc surface of the arc plate 24, and the arc plate 24 is large at one end and small at the other end. When the wastewater enters from the large mouth and flows out to the small hole along the outer wall of the arc plate 24, the water flow velocity flowing out of the arc plate 24 will be increased. Through the application of the above components, when the equipment is running, the water flow outside the bubble column can increase the contact area between the liquid and the bubbles through the application of the arc plate 24, thereby improving the aeration efficiency.

[0039] For example 2, please refer to Figure 4 - Fig. 9The present invention is an aeration device for water treatment. On the basis of the first embodiment, the cleaning mechanism 3 includes a scratch frame 31 slidably connected to the outer wall of the five blades 21, a support rod 32 is rotatably connected to the side wall of the scratch frame 31, an inclined plate 33 is fixedly connected to the outer wall of the support rod 32, a scratch component 4 is fixedly connected to the side wall of the inclined plate 33, and a control component 5 is fixedly connected to the side wall of the scratch frame 31. By utilizing the rotation characteristics of the above-mentioned blades 21, a cleaning mechanism 3 is arranged inside the device. When the blades 21 rotate due to high-pressure bubbles, the inclined plate 33 also contacts with the external wastewater, which is presented as follows Figure 4 When the fan blade 21 rotates clockwise due to the high-pressure bubbles, the external liquid will also contact the left side of the inclined plate 33. At this time, the inclined plate 33 is pushed by the water flow and will drive the scratch frame 31 to move horizontally to the right along the outer wall of the fan blade 21 through the support rod 32. At this time, as the scratch frame 31 moves horizontally, the side wall of the inclined plate 33 will contact one end of the spring telescopic rod 34, and as the inclined plate 33 moves outward, the spring telescopic rod 34 is compressed and deformed.

[0040] The cleaning mechanism 3 also includes a spring telescopic rod 34 fixedly connected to the side wall of the fan blade 21, an inclined panel 35 fixedly connected to the side wall of the fan blade 21, and two sliding frames 36 fixedly connected to the top of the scratch frame 31.

[0041] The cleaning mechanism 3 also includes an L-shaped slide 37 slidably connected to the inner walls of the two sliding frames 36, a spring 38 is fixedly connected to the side wall of the L-shaped slide 37, one end of the spring 38 away from the L-shaped slide 37 is fixedly connected to the side wall of the sliding frame 36, and a roller 39 is fixedly connected to the side wall of the L-shaped slide 37.

[0042] The cleaning mechanism 3 also includes an inclined hook plate 310 fixedly connected to both ends of the support rod 32, an inclined panel 2 311 fixedly connected to the side wall of the fan blade 21, and a spring telescopic rod 2 312 fixedly connected to the side wall of the fan blade 21. As the support rod 32 moves outward, the side wall of the roller 39 will contact the inclined surface of the inclined panel 1 35, presenting a Figure 5 The L-shaped plate 37 releases the restriction on the inclined hook plate 310 and the inclined plate 33. At this time, the inclined plate 35 will release the mechanical power, so that the inclined plate 33 and the support rod 32 will swing around the connection point, so that the inclined plate 33 drives the inclined hook plate 310 at the other end to insert into the L-shaped plate 37 at the other end, so that the inclined plate 33 will no longer swing after the swing is completed. Through the application of the above-mentioned components, the scratch frame 31 can clean the outer wall of the fan blade 21 for a long time when the equipment is running, so as to avoid the accumulation of impurities on the outer wall of the fan blade 21 and affect the efficiency of the arc plate 24 in guiding the water flow.

[0043] The scraping assembly 4 includes two slide grooves 41 opened on the side wall of the inclined plate 33, a sliding scraper 42 is slidably connected to the inner wall of one slide groove 41, and a spring 2 43 is fixedly connected to the side wall of the sliding scraper 42. The end of the spring 2 43 away from the sliding scraper 42 is fixedly connected to the inner wall of the slide groove 41. By utilizing the characteristic that the above-mentioned scraping frame 31 slides along the outer wall of the fan blade 21, a scraping assembly 4 is arranged inside the device. When the inclined plate 33 moves due to the external water flow, the external water flow will also flow along the outer wall of the inclined plate 33, presenting a Figure 7 When the external water flows from bottom to top, the water will contact the outer wall of the sliding scraper 42, forcing the sliding scraper 42 to slide outward along the inner wall of the slide groove 41 and squeeze the spring 2 43, so that the spring 2 43 accumulates mechanical power.

[0044] The scraping assembly 4 also includes a sliding scraper 2 44 slidably connected to the inner wall of another slide groove 41, and a spring 3 45 is fixedly connected to the side wall of the sliding scraper 2 44, and the end of the spring 345 away from the sliding scraper 2 44 is fixedly connected to the inner wall of the slide groove 41. When the inclined plate 33 reaches the edge and swings, the contact surface between the inclined plate 33 and the wastewater will change. The side of the inclined plate 33 close to the sliding scraper 2 44 will directly contact the external wastewater, forcing the sliding scraper 2 44 to slide along the inner wall of the slide groove 41. At this time, the side of the inclined plate 33 close to the sliding scraper 1 42 is on the back of the water. At this time, the pressure on the sliding scraper 1 42 is reduced. Under the push of the spring 2 43, the sliding scraper 1 42 slides outward along the inner wall of the slide groove 41 to remove most of the impurities on the outer wall of the inclined plate 33. Through the application of the above-mentioned components, the impurities on the outer wall of the inclined plate 33 are removed, and the impurities in the wastewater are prevented from accumulating on the outer wall of the inclined plate 33, affecting the turning speed of the inclined plate 33.

[0045] The control component 5 includes five hydraulic telescopic rods 51 connected through the side wall of the rotating tube 12, and one end of the five hydraulic telescopic rods 51 away from the rotating tube 12 is fixedly connected to the outer wall of the scratch frame 31, and one end of the hydraulic telescopic rod 51 away from the scratch frame 31 is connected through an L-shaped tube 52.

[0046] The control component 5 also includes a hydraulic tube 53 which is connected to the end of the L-shaped tube 52 away from the hydraulic telescopic rod 51. A piston plate 54 is slidably connected to the inner wall of the hydraulic tube 53. A fixing rod 55 is fixedly connected to the bottom of the piston plate 54. The five fixing rods 55 are fixedly connected to a fixing ring 56 at one end away from the piston plate 54. A spring 57 is fixedly connected to the bottom of the fixing ring 56. By utilizing the characteristics of the above-mentioned multiple inclined plates 33 driving the corresponding scratch frame 31 to slide, a control component 5 is arranged inside the equipment. When the scratch frame 31 moves outward, the hydraulic telescopic rod 51 is pulled, so that the hydraulic telescopic rod 51 draws the liquid inside the hydraulic tube 53 through the L-shaped tube 52, forcing the piston plate 54 to slide upward along the inner wall of the hydraulic tube 53. In this process, the multiple piston plates 54 drive the fixing ring 56 to slide upward through the corresponding fixing rods 55, presenting a Figure 8 During this process, the fixing ring 56 will limit the speed and height of the upward movement of the multiple piston plates 54, and indirectly control the length and speed of the multiple hydraulic telescopic rods 51 extending outward. Through the application of the above components, the speed and length of the outward movement of the scratch frame 31 are guaranteed to be equal, avoiding unequal pressure on each fan blade 21 and affecting the rotation speed of the fan blade 21.

[0047] The method for using the aeration device for water treatment includes the following steps:

[0048] S1: Install the device: Before use, connect the device to the external high-pressure gas pipe through the threaded pipe 11;

[0049] S2: Start the device: When the high-pressure gas is ejected outward through the aerator 1, the high-pressure gas column generated by the aerator 1 will contact the inclined blades 21, and the upward high-pressure bubbles will provide a lateral force for the blades 21, forcing the five blades 21 to drive the rotating tube 12 to rotate.

[0050] A specific application of this embodiment is: before use, the device is connected to an external high-pressure air pipe through a threaded tube 11. When the high-pressure gas is ejected outward through the aerator 1, the high-pressure air column generated by the aerator 1 will contact the inclined blades 21, and the upward high-pressure bubbles will provide a lateral force for the blades 21, forcing the five blades 21 to drive the rotating tube 12 to rotate. The rotating blades 21 drive the arc plate 24 to rotate synchronously through the fixed bracket 22 and the fixed plate 23. In this process, the rotating arc plate 24 contacts the wastewater outside the bubble column, forcing the external wastewater to approach the rotating tube 12 along the arc surface of the arc plate 24, and the arc plate 24 is large at one end and small at the other end. When the wastewater enters from the large mouth and flows out to the small hole along the outer wall of the arc plate 24, the water flow velocity out of the arc plate 24 will be increased. Through the application of the above-mentioned components, when the device is running, the water flow outside the bubble column can increase the contact surface between the liquid and the bubbles through the application of the arc plate 24, thereby improving the aeration efficiency.

[0051] Taking advantage of the rotating characteristics of the fan blades 21, a cleaning mechanism 3 is provided inside the device. When the fan blades 21 rotate due to high pressure bubbles, the inclined plate 33 also contacts the external wastewater, which is as shown in FIG. Figure 4 When the fan blade 21 rotates clockwise due to the high-pressure bubble, the external liquid will also contact the left side of the inclined plate 33. At this time, the inclined plate 33 is pushed by the water flow and will drive the scratch frame 31 to move horizontally to the right along the outer wall of the fan blade 21 through the support rod 32. At this time, as the scratch frame 31 moves horizontally, the side wall of the inclined plate 33 will contact one end of the spring telescopic rod 34, and as the inclined plate 33 moves outward, the spring telescopic rod 34 is compressed and deformed. Finally, as the support rod 32 moves outward, the side wall of the roller 39 will contact the inclined surface of the inclined plate 35, presenting a Figure 5 The L-shaped plate 37 releases the restriction on the inclined hook plate 310 and the inclined plate 33. At this time, the inclined plate 35 will release the mechanical power, so that the inclined plate 33 and the support rod 32 will swing around the connection point, so that the inclined plate 33 drives the inclined hook plate 310 at the other end to insert into the L-shaped plate 37 at the other end, so that the inclined plate 33 will no longer swing after the swing is completed. Through the application of the above-mentioned components, the scratch frame 31 can clean the outer wall of the fan blade 21 for a long time when the equipment is running, so as to avoid the accumulation of impurities on the outer wall of the fan blade 21 and affect the efficiency of the arc plate 24 in guiding the water flow.

[0052] Taking advantage of the fact that the scratch frame 31 slides along the outer wall of the fan blade 21, a scratch assembly 4 is provided inside the device. When the inclined plate 33 moves due to the external water flow, the external water flow will also flow along the outer wall of the inclined plate 33, presenting a Figure 7When the external water flows from bottom to top, the water will contact the outer wall of the sliding scraper 42, forcing the sliding scraper 42 to slide outward along the inner wall of the chute 41 and squeeze the spring 2 43, so that the spring 2 43 accumulates mechanical power; when the inclined plate 33 reaches the edge and swings, the contact surface of the inclined plate 33 and the wastewater will change, and the side of the inclined plate 33 close to the sliding scraper 2 44 will directly contact the external wastewater, forcing the sliding scraper 2 44 to slide along the inner wall of the chute 41, while the side of the inclined plate 33 close to the sliding scraper 1 42 is on the back of the water. At this time, the pressure on the sliding scraper 1 42 is reduced, and the sliding scraper 1 42 is pushed by the spring 2 43 to slide outward along the inner wall of the chute 41 to remove most of the impurities on the outer wall of the inclined plate 33. Through the application of the above-mentioned components, the impurities on the outer wall of the inclined plate 33 are removed, and the impurities in the wastewater are prevented from accumulating on the outer wall of the inclined plate 33, affecting the turning speed of the inclined plate 33.

[0053] Taking advantage of the characteristic that the above-mentioned multiple inclined plates 33 drive the corresponding scratch frame 31 to slide, a control component 5 is arranged inside the device. When the scratch frame 31 moves outward, the hydraulic telescopic rod 51 is pulled, so that the hydraulic telescopic rod 51 extracts the liquid inside the hydraulic pipe 53 through the L-shaped pipe 52, forcing the piston plate 54 to slide upward along the inner wall of the hydraulic pipe 53. In this process, the multiple piston plates 54 drive the fixing ring 56 to slide upward through the corresponding fixing rod 55, presenting a Figure 8 During this process, the fixing ring 56 will limit the speed and height of the upward movement of the multiple piston plates 54, and indirectly control the length and speed of the multiple hydraulic telescopic rods 51 extending outward. Through the application of the above components, the speed and length of the outward movement of the scratch frame 31 are guaranteed to be equal, avoiding unequal pressure on each fan blade 21 and affecting the rotation speed of the fan blade 21.
