Description

Technical Field

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious, especially in urban rivers, lakes and other water bodies, which often appear black and smelly. Black and smelly water bodies not only affect the urban landscape, but also pose a threat to human health and the ecological environment. The formation of black and smelly water bodies is mainly due to the excessive content of organic matter in the water body, which is decomposed by microorganisms under anaerobic conditions, producing black and smelly substances such as hydrogen sulfide and ammonia.

[0003] In the process of water treatment, it is necessary to salvage organic matter on the surface of the water. However, during the salvage process, the organic matter in the water cannot be effectively removed, which not only wastes manpower but also reduces the efficiency of organic matter salvage. In the traditional treatment process, the release of chemicals is uneven, and the uniform purification and disinfection of the water cannot be ensured, resulting in incomplete water purification. The low oxygen content in the water will affect the survival of aquatic organisms and water quality.

[0004] Therefore, there is a need for a black and odorous water treatment device for ecological restoration to solve the technical problems in the prior art of being unable to effectively remove organic matter in water, uneven release of agents and low oxygen content in water. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a black and odorous water treatment device for ecological restoration. The present application places the device below the horizontal plane, and the water flow drives the organic matter on the surface of the water body to be filtered. At the same time, the external air is extracted and pressurized by the floating method of the water flow to scrape the filtered organic matter, and the air pressure difference is used to make the device float out of the horizontal plane. The drive shaft is reversed to collect the scraped organic matter, and the air pressure difference exhaust method can also discharge the gas into the water body. The water body is guided and extracted when floating up and down, so that the organic matter is filtered following the water flow, which solves the technical problems of the inability to effectively remove organic matter in the water and the low oxygen content of the water body in the prior art. In addition, as the collected water level rises, it ensures that the agent is released in time and avoids water backflow. The water mixed with the agent can also be sprayed into the water body, which solves the technical problem of uneven agent release in the prior art.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows: 1.

The reverse rotation of the transmission shaft can also collect the scraped organic matter. The air pressure difference method can also discharge the gas in the airbag ring into the water body, so that the top of the guide box sinks to the water surface.

Water flows into the water storage chamber. As the water level continues to rise, the medicine in the medicine box is poured into the water through the guide groove and the connecting hole. As the water level continues to rise, the connecting hole is blocked to prevent water from flowing back into the medicine box. Then the water mixed with the medicine is sprayed into the external water body to purify and disinfect the water body. 4. As the amount of air entering the protection box gradually increases, the air pressure in the protection box increases, and the air flow enters the air bag ring through the one-way valve in one direction to inflate the air bag ring. As the air pressure in the air bag ring gradually increases, the air bag ring generates buoyancy, driving the guide box out of the water, and the water flow cannot enter the guide box. The pressure in the air bag ring cooperates with the water body to squeeze the air bag ring, increasing the pressure in the air bag ring. The air flow is discharged from the air bag ring through the automatic vent valve in one direction, and the air is output into the water body, increasing the oxygen content in the water body. At the same time, the buoyancy is reduced, and the guide box moves below the horizontal plane. BRIEF DESCRIPTION OF THE DRAWINGS

As the airbag ring 62 is continuously inflated, the airbag ring 62 generates buoyancy, driving the medicine box 2, the water storage tank 3 and the guide box 4 to move. The water storage tank 3 moves on the protection box 1, and the guide box 4 When the air bag ring 62 is extended out of the water, the pressure in the air bag ring 62 continues to increase. When the air pressure in the air bag ring 62 exceeds the limit value of the automatic vent valve 63, the air in the air bag ring 62 is discharged into the water body, the buoyancy disappears, the guide box 4 moves under the water surface, the water storage tank 3 drives the transmission shaft 502 to move, the transmission shaft 502 drives the gear cover 515 to approach the transmission gear 514, the cone of the bottom wall of the gear cover 515 is guided by the cone of the top wall of the transmission gear 514, and the gear cover 515 is in transmission connection with the transmission gear 514; When the top wall of the guide box 4 is lower than the water plane, the air inlet impeller 508 drives the transmission gear 514 to rotate, the transmission gear 514 drives the gear cover 515 to rotate, the gear cover 515 drives the transmission shaft 502 to rotate, the transmission shaft 502 drives the water guide plate 701 and the filter screen 702 to rotate, the scraper 704 scrapes off the filtered organic matter, the filter screen 702 drives the rotating shaft 705 and the lifting screw 706 to rotate, the bare rod end of the lifting screw 706 contacts the driving frame 707, the transmission shaft 502 twists the torsion spring 511, when the torsion spring 511 twists to the limit, the magnet ring 509 and the magnet block 510 are separated from the magnetic attraction, the transmission shaft 502 drives the torsion spring 511 to rotate, and at the same time drives the magnet block 510 to rotate on the bottom wall of the water storage tank 3. When the guide box 4 extends out of the water, the water tank 3 drives the transmission shaft 502 to move, and the transmission shaft 502 drives the gear cover 515 away from the transmission gear 514. The gear cover 515 and the transmission gear 514 cannot be connected in transmission, and the gear cover 515 cannot twist the torsion spring 511 through the transmission shaft 502. The torsion spring 511 is reset. At the same time, the magnet ring 509 and the magnet block 510 are magnetically attracted, driving the transmission shaft 502 to rotate in the opposite direction, driving the water guide plate 701 and the filter screen 702 to rotate in the opposite direction, and driving the lifting screw 706 to rotate in the opposite direction. The threaded end is threadedly connected to the driving frame 707, and the driving frame 707 drives the baffle 708 to move, and the baffle 708 is away from the discharge groove. The scraper 704 pushes the scraped organic matter into the waste shell 901 through the discharge groove. When the guide box 4 moves under the water surface, the water flows into the guide pipe 501, and the transmission shaft 502 rotates, driving the lifting screw 706 to rotate, pushing the baffle 708 close to the discharge groove. When the baffle 708 blocks the discharge groove, the bare rod end of the lifting screw 706 is not threadedly connected to the driving frame 707, and cannot drive the baffle 708 to continue to move; Discharging waste: the discharging motor 904 is started, and the discharging motor 904 drives the discharging auger 903 to rotate in the discharging pipe 902 and the waste shell 901, and the organic matter in the waste shell 901 is discharged to the shore through the discharging auger 903.

[0027] The present invention and its implementation methods are described above, which is not restrictive. The drawings are only one of the implementation methods of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
