Description

Technical Field

[0001] This invention relates to the field of water purification technology, specifically to a solar-powered aeration and propulsion device for post-engineering river water purification. Background Technology

[0002] After river channel improvement or engineering construction is completed, some river sections have weak water renewal capacity and are prone to forming local stagnant water areas. This leads to a gradual decrease in dissolved oxygen in the water. At the same time, due to insufficient exchange between the upper and lower layers of the water, obvious water stratification often occurs, causing the bottom water to be in a state of hypoxia for a long time. This is not conducive to the restoration of the water's self-purification capacity and thus affects the overall ecological environment of the river.

[0003] Currently, common treatment methods for purifying river water quality after engineering projects include aeration and oxygenation, water propulsion, and ecological floating beds. However, existing aeration and propulsion devices mostly adopt aeration and propulsion structures with fixed depths. The installation positions of the aeration disc and the propulsion impeller are fixed, making it difficult to flexibly adjust the aeration depth and propulsion depth according to the differences in water depth, water pollution level, and water stratification in different sections of the river after the project. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a solar-powered aeration and propulsion device for post-engineering river water purification, solving the problem that the fixed installation positions of the aeration disc and propulsion impeller make it difficult to adapt to different depths and water stratification changes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a solar-powered aeration and propulsion device for post-engineering river water purification, comprising a float, a fixed frame, a control box, and an aeration pump mounted on the upper surface of the float, a solar panel mounted on the outer wall of the fixed frame, a hose connected to the output end of the aeration pump, an aeration disc connected to the bottom end of the hose, a fixed rod slidably connected inside the aeration disc, the top end of the fixed rod mounted on the lower surface of the float, a counterweight and a shaped frame mounted on the lower surface of the aeration disc, a waterproof motor mounted inside the shaped frame, an impeller fixedly mounted on the output end of the waterproof motor, a motor body mounted on the upper surface of the float, a winding wheel fixedly mounted on the output end of the motor body, a rope mounted on the outer wall of the winding wheel, the bottom end of the rope mounted on the outer wall of the aeration disc, and a planting ring mounted on the outer wall of the float.

[0006] The above solution involves using solar panels to absorb solar energy and convert it into electricity to power the aeration pump, waterproof motor, and motor body. The control box is used to control the operation of the motor and aeration pump, as well as manage electrical energy. Through the cooperation of the aeration discs, hoses, and aeration discs, outside air is transported and dispersed into bubbles to increase dissolved oxygen in the water and improve the living environment for aquatic organisms. The waterproof motor and impeller drive the water flow and disturb the water layer to solve the problem of water stratification and stagnation after the project and promote water circulation.

[0007] Preferably, a cleaning mechanism is provided on the lower surface of the float. The cleaning mechanism includes a guide cylinder, the upper surface of which is installed on the lower surface of the float. A transmission cylinder is provided inside the guide cylinder. One end of a spring is fixedly connected to the upper surface of the transmission cylinder, and the other end of the spring is fixedly connected to the lower surface of the float.

[0008] Preferably, a fixing frame is fixedly connected to the lower surface of the transmission cylinder, a scraper is installed on the lower surface of the fixing frame, the outer wall of the scraper is disposed on the outer wall of the conical block, and the lower surface of the scraper is disposed on the upper surface of the aeration disc.

[0009] Preferably, the outer wall of the hose is disposed inside the float, the outer wall of the winding wheel is rotatably connected to the inside of the fixed frame, the inside of the irregular frame is slidably connected to the outer wall of the fixed rod, and the outer wall of the rope is slidably connected to the inside of the float.

[0010] Preferably, a conical block is installed on the upper surface of the aeration disc and the lower surface of the irregular frame. The conical block is slidably connected to the outer wall of the fixed rod, and an impeller is installed on the outer wall of the irregular frame.

[0011] Preferably, a support ring is fixedly connected to the outer wall of the float, the outer wall of the support ring is disposed inside the planting ring, a plurality of arc-shaped pieces are installed on the lower surface of the planting ring, and a limit ring is installed on the lower surface of the planting ring.

[0012] Preferably, a hollow block is installed inside the float, and a transmission frame is slidably connected inside the hollow block.

[0013] Preferably, one end of the second spring is fixedly connected to the outer wall of the transmission frame, and the other end of the second spring is fixedly connected to the inside of the hollow block.

[0014] Preferably, a transmission plate is slidably connected to the outer wall of the transmission frame, and the interior of the transmission plate is rotatably connected to the interior of the hollow block via a rotating shaft.

[0015] Preferably, a movable block is slidably connected inside the transmission plate, the outer wall of the movable block is slidably connected inside the hollow block, and a sliding rod is fixedly connected to the outer wall of the movable block. The outer wall of the sliding rod passes through the interior of the hollow block and the float and is inserted into the interior of the limiting ring.

[0016] Working principle: After the control box starts the aeration pump, the aeration pump forces air into the hose and delivers it to the aeration disc located underwater. The aeration disc disperses the air into a large number of tiny bubbles and releases them into the water. As the bubbles rise, they come into full contact with the water, thereby increasing the dissolved oxygen content of the water and promoting water exchange, thus improving the river water environment. When the waterproof motor is powered on, it drives the impeller to rotate, which in turn propels the surrounding water, causing the water to flow. Through the motor body, the winding wheel, and the rope, the aeration and propulsion components move up and down as a whole, thus adapting to different water depths or different water quality conditions.

[0017] This invention provides a solar-powered aeration and flow-generating device for post-engineering river water purification. It offers the following advantages: 1. This invention oxygenates water by setting up an aeration disc and an impeller, while simultaneously promoting directional flow of water to disrupt water stratification. The aeration disc and impeller are moved up and down by the motor body, the winding wheel and the rope to adjust the aeration depth and the propulsion depth, making the aeration and propulsion positions more adaptable to the water environment, and also enhancing the water's self-purification ability.

[0018] 2. When the aeration disc is moved to a suitable position, the surface of the conical block and the aeration disc is cleaned by the cleaning mechanism. The mud, algae or other impurities attached to the surface are removed. This not only prevents the aeration holes from being blocked and ensures that air can be released into the water smoothly through the aeration disc, but also keeps the surface of the aeration disc clean and improves the stability and reliability of the device during long-term operation.

[0019] 3. In this invention, after the impeller moves to a suitable position, the impeller rotates to form a directional flow, which pushes the transmission frame and its connecting parts, causing the slide rod to slide out of the inside of the limiting ring, thereby releasing the limiting state of the planting ring and realizing the automatic release or limiting of the planting ring.

[0020] 4. This invention strengthens the directional flow generated by impeller one and impeller two located on the suction side, so that the planting ring is no longer restricted and the arc-shaped plate drives the planting ring to rotate, thereby allowing the water at different positions to fully contact the plant roots, improving the plant's absorption efficiency of nutrients in the water, and thus enhancing the ecological purification effect.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a solar-powered aeration and propulsion device for post-construction river water purification, comprising a float 1, a fixed frame 2, a control box 4, and an aeration pump 5 mounted on the upper surface of the float 1, a solar panel 3 mounted on the outer wall of the fixed frame 2, a hose 6 provided at the output end of the aeration pump 5, an aeration disc 7 connected to the bottom end of the hose 6, a fixed rod 8 slidably connected inside the aeration disc 7, the top end of the fixed rod 8 mounted on the lower surface of the float 1, a counterweight 9 and a shaped frame 10 mounted on the lower surface of the aeration disc 7, a waterproof motor 11 housed inside the shaped frame 10, an impeller 12 fixedly mounted at the output end of the waterproof motor 11, a motor body 13 mounted on the upper surface of the float 1, a winding wheel 14 fixedly mounted at the output end of the motor body 13, a rope 15 provided on the outer wall of the winding wheel 14, the bottom end of the rope 15 mounted on the outer wall of the aeration disc 7, and a planting ring 20 provided on the outer wall of the float 1.

[0025] Specifically, the counterweight 9 provides a downward force to the aeration disc 7 when it is released by the motor body 13, the winding wheel 14, and the rope 15, ensuring that the aeration disc 7 and the irregular frame 10 move downward. A planting ring 20 is provided on the outer wall of the float 1, and aquatic plants can be planted inside the planting ring 20. During the growth process, the aquatic plants can absorb nutrients such as nitrogen and phosphorus in the water and decompose pollutants in the water through the action of root microorganisms, thereby purifying the water ecologically. At the same time, the water flow formed by underwater propulsion can enhance the contact between the water and the plant roots and improve the plant purification efficiency. In actual operation, the device is powered by the solar panel 3 to drive the aeration system and the propulsion system. The aeration disc 7 oxygenates the water, the impeller 12 propels the water to form a circulating flow, and the aeration depth is adjusted by the lifting mechanism to make the aeration effect more stable, thereby achieving continuous oxygenation, circulation disturbance, and ecological purification of the river water after the project.

[0026] Please see the appendix Figure 3 -Appendix Figure 7 A cleaning mechanism 16 is provided on the lower surface of the float 1. The cleaning mechanism 16 includes a guide cylinder 165. The upper surface of the guide cylinder 165 is installed on the lower surface of the float 1. A transmission cylinder 163 is provided inside the guide cylinder 165. One end of a spring 164 is fixedly connected to the upper surface of the transmission cylinder 163. The other end of the spring 164 is fixedly connected to the lower surface of the float 1.

[0027] Specifically, the float 1 provides support for the guide cylinder 165 and its connecting parts. The guide cylinder 165 has an arc-shaped groove inside. The outer wall of the transmission cylinder 163 is provided with a short rod, which slides in the groove to facilitate the rotation of the transmission cylinder 163 when it moves upward. The spring 164 limits the movement of the transmission cylinder 163 and provides a reset force.

[0028] Please see the appendix Figure 3-Appendix Figure 7 A fixed frame 161 is fixedly connected to the lower surface of the transmission cylinder 163. A scraper 162 is installed on the lower surface of the fixed frame 161. The outer wall of the scraper 162 is set on the outer wall of the conical block 17, and the lower surface of the scraper 162 is set on the upper surface of the aeration disc 7.

[0029] Specifically, the scraper 162 is made of rubber or other elastic material to easily adapt to the compression when the aeration disc 7 moves upward. Figure 7 It can be seen that the scraper 162 is set at an angle, with the aeration facing outward. As the scraper 162 and the fixing frame 161 rotate, the debris on the surface of the aeration disc 7 is pushed outward to scrape it away, so as to keep the aeration disc 7 clean.

[0030] Please see the appendix Figure 1 -Appendix Figure 4 The outer wall of the hose 6 is set inside the float 1, the outer wall of the winding wheel 14 is rotatably connected to the inside of the fixed frame 2, the inside of the irregular frame 10 is slidably connected to the outer wall of the fixed rod 8, and the outer wall of the rope 15 is slidably connected to the inside of the float 1.

[0031] Specifically, the hose 6 is set to a suitable length to accommodate the movement of the aeration components, the inside of the fixed frame 2 supports and limits the rotation of the winding wheel 14, and the outer wall of the fixed rod 8 limits the movement of the irregular frame 10.

[0032] Please see the appendix Figure 4 Conical blocks 17 are installed on the upper surface of the aeration disc 7 and the lower surface of the irregular frame 10. The interior of the conical blocks 17 is slidably connected to the outer wall of the fixed rod 8. An impeller 18 is installed on the outer wall of the irregular frame 10.

[0033] Specifically, by setting the conical block 17, the outer wall of the fixed rod 8 is cleaned when the aeration disc 7 and the irregular frame 10 move up and down, so as to ensure the normal movement of the aeration disc 7 and the irregular frame 10. By setting the impeller 18, when the flow propulsion component forms a directional flow, its suction side drives the water flow to make the impeller 18 rotate, so as to strengthen the range of directional flow.

[0034] Please see the appendix Figure 5 A support ring 19 is fixedly connected to the outer wall of the float 1. The outer wall of the support ring 19 is located inside the planting ring 20. Multiple arc-shaped pieces 22 are installed on the lower surface of the planting ring 20. A limit ring 21 is installed on the lower surface of the planting ring 20.

[0035] Specifically, the support ring 19 not only supports the planting ring 20, but also provides an installation position for the planting ring 20. The arc-shaped pieces 22 are arranged in a ring, which facilitates the rotation of the planting ring 20 by the driving force of the propulsion component. The limiting ring 21 has multiple grooves inside, which, with the cooperation of the limiting component, limit or release the rotation of the planting ring 20.

[0036] Please see the appendix Figure 8 The interior of the float 1 is fitted with a hollow block 23, and the interior of the hollow block 23 is slidably connected to a transmission frame 24.

[0037] Specifically, the internal space of the hollow block 23 facilitates the movement of its internal components, while simultaneously restricting the movement of the transmission frame 24.

[0038] Please see the appendix Figure 8 -Appendix Figure 9 One end of spring 25 is fixedly connected to the outer wall of the transmission frame 24, and the other end of spring 25 is fixedly connected to the inside of the hollow block 23.

[0039] Specifically, by setting spring 25, after the transmission frame 24 is moved by external force, it provides a restoring elastic force for the transmission frame 24.

[0040] Please see the appendix Figure 8 -Appendix Figure 9 The outer wall of the transmission frame 24 is slidably connected to the transmission plate 26, and the interior of the transmission plate 26 is rotatably connected to the interior of the hollow block 23 via a rotating shaft.

[0041] Specifically, the hollow block 23 has a rotating part inside to support the rotation of the transmission plate 26, and the transmission plate 26 has a groove inside to facilitate the sliding of the short rod on the outer wall of the transmission frame 24 to transmit power to the transmission plate 26.

[0042] Please see the appendix Figure 8 -Appendix Figure 9 The transmission plate 26 has a sliding block 27 inside, the outer wall of the sliding block 27 is slidably connected to the inside of the hollow block 23, and the outer wall of the sliding block 27 is fixedly connected to a slide rod 28. The outer wall of the slide rod 28 passes through the interior of the hollow block 23 and the float 1 and is inserted into the interior of the limiting ring 21.

[0043] Specifically, the movement of the movable block 27 is offset and restricted by the interior of the hollow block 23, thereby guiding the slide rod 28 to move. The slide rod 28 is inserted into the limiting ring 21 on the side away from the movable block 27. When there is no external force driving the transmission plate 26 to rotate, the slide rod 28 is pushed by the elastic component and limits the limiting ring 21 and its connecting components on its own.

[0044] Workflow: After the float 1 floats on the water surface, the solar panel 3 converts solar energy into electrical energy under sunlight, and the electrical energy is transmitted to the control box 4 for storage and control. The control box 4 manages the power supply of each electrical device. After the aeration pump 5 is controlled by the control box 4, air is forced into the hose 6 and delivered downward to the aeration disc 7. The aeration disc 7 disperses the air into a large number of fine bubbles underwater and releases them into the water. The bubbles fully contact the water as they rise, thereby increasing the dissolved oxygen content of the water. At the same time, after the waterproof motor 11 starts, it drives the impeller 12 to rotate, which pushes the surrounding water and causes the water to flow in a directional manner, thereby driving water circulation and breaking up any water stratification that may form in the river channel after the project. Planting plants are planted through the planting ring 20 to facilitate decontamination and improve water quality.

[0045] When the position of the propulsion system needs to be adjusted, the motor body 13 drives the winding wheel 14 to rotate, which winds up or releases the rope 15. This causes the aeration disc 7, the irregular frame 10, and the impeller 12 to move up and down under the guidance of the fixed rod 8, so as to change the working depth of the aeration disc 7 and the impeller 12. This allows the device to adapt to different water depths or different water conditions, so as to better solve the problem of water stratification.

[0046] After the aeration disc 7 moves to the appropriate position, the upper side of the cone block 17 and the aeration disc 7 contacts the outer wall of the scraper 162. As it continues to move upward, it pushes the scraper 162, the fixing frame 161 and the transmission cylinder 163 upward, squeezing the spring 164. Under the action of the groove inside the guide cylinder 165, the transmission cylinder 163 is guided to rotate, causing the spring 164 to deform. The scraper 162 rotates with the transmission cylinder 163 through the fixing frame 161, thereby cleaning the surface of the cone block 17 and the aeration disc 7 and reducing the impact of debris on the aeration disc 7.

[0047] After the impeller 12 moves to the appropriate position, the thrust generated by the impeller 12 pushes the transmission frame 24 to compress the spring 25. The transmission frame 24 drives the transmission plate 26 to rotate, thereby causing the moving block 27 and the slide rod 28 to move in opposite directions. This causes the slide rod 28 to slide out of the limiting ring 21 and no longer limit the planting ring 20. Then, the water flow pushes the arc-shaped plate 22, thereby pushing the planting ring 20 to rotate under the support of the support ring 19, so that the plant roots can form a more complete contact with the surrounding water.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
