Technical Field
[0001] This invention relates to the field of water purification equipment, specifically a reservoir water purification device. Background Technology
[0002] Reservoirs serve as crucial carriers for urban and rural water supply, ecological conservation, and flood control in my country, and their water quality directly impacts water supply security and the health of the aquatic ecosystem. In recent years, affected by factors such as non-point source pollution and endogenous release from bottom sediments, some reservoirs have experienced problems such as eutrophication, seasonal bottom anaerobic conditions, and accumulation of surface algae and floating debris. There is an urgent need for efficient, low-maintenance in-situ water purification equipment for long-term, routine treatment.
[0003] In the field of underwater aeration and purification, existing technologies mostly employ fixed microporous aeration devices. These devices fix the aeration discs at a specific depth at the bottom of the reservoir and supply compressed air via onshore air supply equipment to continuously release microbubbles into the water to increase dissolved oxygen levels. While this approach is simple in structure, it only oxygenates a small area of water around a fixed depth. It struggles to overcome the density barrier of the thermocline formed in reservoirs during spring and summer, failing to effectively break down the stratification of the upper and lower water layers. The anaerobic environment at the bottom and the release of pollutants from the sediment are difficult to fundamentally improve, and the effect on increasing the uniformity of dissolved oxygen across the entire water layer is very limited. In the field of treating floating pollutants on the water surface, existing technologies are mainly divided into three categories: manual removal, fixed floating debris barriers, and motorized cleaning equipment. Manual dredging operations are inefficient, costly, and pose safety risks, making them unsuitable for the routine management needs of large reservoirs. Fixed debris-blocking rafts can only passively intercept floating debris drifting with the water flow, unable to actively collect surrounding scum. They are also greatly affected by reservoir water level fluctuations and wave impacts, and are prone to leakage and scum overflow when the water level is too high or too low. While motorized surface cleaning vessels or floating filter devices can actively move and collect scum, they generally require independent drive systems and electrical control units, resulting in high equipment manufacturing costs. Moreover, most of them only have a single cleaning function and cannot simultaneously improve the dissolved oxygen and water quality of the underwater body.
[0004] Therefore, a solution is proposed. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a reservoir water purification device that solves the problems mentioned in the background section.

One end of the hinge rod is movably connected to the bottom end of the trigger rod, and the other end of the hinge rod is movably connected to an adjusting plate. The adjusting plate is slidably disposed in the connecting pipe to adjust the ventilation cross-sectional area. A reciprocating air supply assembly is provided on the top of the main frame of the equipment. The reciprocating air supply assembly is connected to the air storage chamber via a connecting pipe. A filter bucket lifting transmission assembly is also provided on the top of the main frame of the equipment. The filter bucket lifting transmission assembly is drivenly connected to the reciprocating air supply assembly. The filter bucket is suspended by a connecting strip in the filter bucket lifting transmission assembly.
[0007] Preferably, the reciprocating air supply assembly includes an air supply drive motor, a fixed cylinder, a rotating disk, and a hinged rod. The fixed cylinder is horizontally fixed to the inner side of the main frame of the equipment. A sealing piston is slidably disposed inside the fixed cylinder. The air supply drive motor is vertically mounted on the top of the main frame of the equipment. The rotating disk is coaxially fixedly connected to the lower end of the output shaft of the air supply drive motor. A swing rod is hinged to the eccentric position of the swing disk. The end of the swing rod is hinged to the sealing piston, together forming a crank-slider type reciprocating pump structure.
[0008] Preferably, the ends of the fixed cylinder are respectively connected to a connecting pipe and an air inlet one-way pipe. An air outlet one-way valve is provided in the connecting pipe, and an air inlet one-way valve is provided in the air inlet one-way pipe. The two one-way valves have opposite conduction directions.
[0009] Preferably, the bottom opening of the mounting cover extends downward in a funnel shape, a waterproof sleeve is provided between the trigger rod and the through hole at the top of the mounting cover, and the top end of the trigger rod extends out of the top of the mounting cover to abut against the bottom of the main frame of the equipment for triggering.
[0010] Preferably, the filter barrel lifting transmission assembly includes a mounting base, a rotating shaft, a drive gear, and a drive rack. The mounting base is fixed to the top of the main equipment frame. The rotating shaft is horizontally mounted on the mounting base via bearings. Both ends of the rotating shaft are coaxially fixed with drive gears. A connecting shell is fixedly connected to the top of the main equipment frame. The drive rack is vertically slidably assembled inside the connecting shell and meshes with the drive gear. The bottom end of the drive rack is suspended and connected to the filter barrel via multiple connecting strips.
[0011] Preferably, a connecting shaft is rotatably connected to the inner side of the mounting base via a bearing. One end of the connecting shaft is coaxially and fixedly connected to the rotating disk, and an incomplete bevel gear is fixed to the other end of the connecting shaft. A transmission shaft is coaxially fixed to the middle of the rotating shaft, and two driven bevel gears are symmetrically fixed to the outer side of the transmission shaft. The incomplete bevel gear alternately meshes with the two driven bevel gears to drive the rotating shaft to reciprocate in both forward and reverse directions, thereby causing the drive rack to drive the filter barrel to perform vertical reciprocating motion.
[0012] Preferably, a photovoltaic solar panel is installed at the top of the main frame of the equipment, and the photovoltaic solar panel is electrically connected to the gas supply drive motor through an energy storage control module, and a thruster is provided at the bottom of the main frame of the equipment.

When the mounting cover rises to the point where the trigger rod abuts against the bottom of the main frame of the equipment, the trigger rod presses down to drive the hinge rod to swing, thereby driving the adjusting plate to slide and increase the effective ventilation area of the connecting pipe.
[0015] This invention provides a reservoir water purification device. It has the following beneficial effects: 1. This invention adopts a vertically reciprocating installation cover structure. It relies on the change in air volume in the air storage chamber to change the overall buoyancy. With the linkage of the trigger rod, hinge rod and adjustment plate, it realizes automatic lifting and cycling, which drives the microporous aeration disc to complete the progressive aeration of the entire water layer from the bottom to the surface of the reservoir. It effectively breaks the density barrier of the thermocline layer of the reservoir, promotes the exchange of water between the upper and lower parts and the uniform distribution of dissolved oxygen, improves the anaerobic state of the bottom water and inhibits the release of endogenous pollutants in the bottom sediment. At the same time, the lifting power comes from the aeration supply itself, without the need to set up an additional underwater lifting drive device, avoiding the risk of underwater motor seal failure, and significantly improving the reliability of the equipment for long-term underwater operation.
[0016] 2. This invention adopts a filter barrel structure that can move vertically back and forth. The filter barrel is driven by a gear and rack transmission mechanism to periodically cut into and lift out of the water surface. When moving downward, it can actively carry surface scum into the barrel for interception and collection. When moving upward, gravity is used to dehydrate the scum in the barrel and achieve reverse self-cleaning of the filter holes. This not only adapts to the working conditions of undulating water surface in reservoirs and expands the effective window for scum capture, but also forms a local gathering flow field in the surface water through reciprocating motion, actively collecting surrounding floating pollutants, effectively improving the efficiency and coverage of scum collection.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see the appendix Figure 1 - Appendix Figure 9This invention provides a reservoir water purification device, including a main frame 1, which serves as the main load-bearing structure of the entire device. The upper structure is exposed above the water surface, while the lower structure is submerged in the reservoir water. Two vertically extending guide rail columns 44 are symmetrically fixed to the outer side of the main frame 1. Vertical guide rails 42 are fixedly connected to the opposing side walls of the two guide rail columns 44. Rubber buffer limit blocks are provided at both the upper and lower ends of the vertical guide rails 42 to limit the extreme stroke of the lifting slider 43 and reduce the impact load at the end of the stroke. The lifting slider 43 is slidably mounted on the outer side of the vertical guide rails 42. An installation cover 41 is fixedly connected to the outer side of the lifting slider 43 through a horizontally set connecting plate. A microporous aeration disc 7 is fixedly installed on the lower surface of the connecting plate. The aeration surface of the aeration disc 7 is arranged downwards towards the bottom of the reservoir, allowing microbubbles to diffuse downwards and then naturally rise, extending the residence path of the bubbles in the water and improving dissolved oxygen efficiency. The mounting cover 41 is an inverted bell-shaped cavity structure with a closed top and side walls and an open bottom, forming a sealed air storage chamber inside. The bottom opening extends downwards in a funnel shape, increasing the contact area between the lower part of the air chamber and the water, and improving the stability of the air column's rise and fall. An air intake interface is provided on the upper side wall of the mounting cover 41, which is connected to the air inlet of the microporous aeration disc 7 through a connecting pipe 10. The air intake interface is always located in the gas phase area of the air storage chamber, preventing water from entering the aeration passage and ensuring the stability of the aeration supply. A sliding through hole is provided at the center of the top of the mounting cover 41, through which a sliding through hole... A trigger rod 52 is provided in the sliding through hole. A corrugated waterproof sleeve 51 is provided between the trigger rod 52 and the sliding through hole. The upper and lower ends of the waterproof sleeve 51 are respectively sealed and fixed to the rod body of the trigger rod 52 and the top outer wall of the mounting cover 41. Without restricting the vertical sliding of the trigger rod 52, a dynamic seal is achieved at the sliding part to prevent external water from seeping into the gas storage chamber. A return spring is sleeved on the outside of the rod body of the trigger rod 52. The upper end of the return spring abuts against the top inner wall of the mounting cover 41, and the lower end of the return spring abuts against the annular limiting boss provided at the lower part of the trigger rod 52. When the mounting cover 41 rises to the top and the trigger rod 52 moves down due to the pressure from the bottom of the main frame 1, the return spring is compressed and stores force. When the mounting cover 41 moves down and the trigger rod 52 loses its pressure, the return spring is compressed and stores force. When pressure is applied, the return spring releases its elastic force, pushing the trigger rod 52 to slide upward and reset. A hinge rod 53 is hinged to the upper part of the inner wall of the mounting cover 41 via a pivot. One end of the hinge rod 53 is movably hinged to the bottom end of the trigger rod 52, and the other end of the hinge rod 53 is movably connected to an adjusting plate 54. The adjusting plate 54 is embedded in a groove inside the connecting pipe 10 and can slide radially along the connecting pipe 10. A sealing strip is embedded on the side of the adjusting plate 54, and the sealing strip fits tightly against the inner wall of the connecting pipe 10 to ensure airtightness during the sliding adjustment process. When the trigger rod 52 is pressed downward, it pushes the hinge rod 53 to swing around the fulcrum, driving the adjusting plate 54 to slide along the groove via lever transmission, increasing the effective ventilation cross-sectional area of the connecting pipe 10. When the trigger rod 52 resets and moves upward...The adjusting plate 54 returns to its original position synchronously with the hinge rod 53, restoring the ventilation cross-sectional area to its initial state.
[0021] A reciprocating air supply assembly is installed on the top of the main frame 1. The reciprocating air supply assembly includes an air supply drive motor, a fixed cylinder 91, a rotating disk 92, and a swing rod 93. The fixed cylinder 91 is horizontally fixedly installed on a mounting bracket inside the main frame 1. A sealing piston is slidably installed inside the fixed cylinder 91, and multiple layers of wear-resistant sealing rings are embedded circumferentially on the sealing piston to form a dynamic seal with the inner wall of the fixed cylinder 91. The output shaft of the air supply drive motor passes downward through the top plate of the main frame 1 and is coaxially fixedly connected to the rotating disk 92. A hinge seat is provided at an eccentric position on the surface of the rotating disk 92, and a swing rod 93 is hinged to the hinge seat. The other end of the swing rod 93 is connected to a joint shaft. The end of the bearing is hinged to the sealing piston. The end of the fixed cylinder 91 is connected to the connecting pipe 94 and the air inlet one-way pipe respectively. The connecting pipe 94 is equipped with an air outlet one-way valve, and the air inlet one-way pipe is equipped with an air inlet one-way valve. The two one-way valves have opposite conduction directions. The top of the main frame 1 of the equipment is also equipped with a filter bucket lifting transmission assembly. The filter bucket lifting transmission assembly is connected to the reciprocating air supply assembly. The filter bucket 31 is suspended at its lower end by the connecting strip 32. The filter bucket lifting transmission assembly includes a mounting base 81, a rotating shaft 34, a drive gear 35, and a drive rack 36. Two sets of mounting bases 81 are provided and are symmetrically fixed on both sides of the top of the main frame 1 of the equipment. The connecting shaft 82 is horizontal through the bearing. The connecting shaft 82 is rotatably mounted inside one set of mounting bases 81. One end of the connecting shaft 82 is coaxially fixedly connected to the outer center of the rotating disk 92 via a coupling, allowing the connecting shaft 82 to rotate synchronously with the rotating disk 92. The other end of the connecting shaft 82 is fixedly mounted with an incomplete bevel gear 83, the teeth of which cover its semi-circular conical surface. The transmission shaft 85 is horizontally rotatably mounted between the two sets of mounting bases 81 via bearings. Two driven bevel gears 84 are symmetrically fixed on the outer side of the transmission shaft 85, with the tooth surfaces of both driven bevel gears 84 facing the side of the incomplete bevel gear 83. When the incomplete bevel gear 83 rotates with the connecting shaft 82, it can alternately mesh with the two driven bevel gears 84. The transmission system converts the continuous rotational motion into the reciprocating forward and reverse rotation of the transmission shaft 85. Both ends of the transmission shaft 85 are coaxially fixedly connected to the rotating shaft 34. The outer end of the rotating shaft 34 extends to the outer side of the mounting base 81 on the corresponding side, and the end of the rotating shaft 34 is coaxially fixedly connected to the drive gear 35. The top of the main frame 1 of the equipment is fixedly connected to the position corresponding to the drive gear 35. The inner side of the connecting shell 33 is provided with a vertical guide groove. The drive rack 36 is vertically slidably assembled in the guide groove, and the tooth surface of the drive rack 36 meshes with the drive gear 35. The bottom end of the drive rack 36 is suspended and connected to the top frame of the filter barrel 31 through multiple connecting strips 32.
[0022] The sidewall of the filter barrel 31 is evenly distributed with permeable filter holes. The diameter of the filter holes can be adapted to the particle size of the target scum. The top of the filter barrel 31 has a scum inlet, and the edge of the scum inlet is provided with an outwardly inclined scum-blocking lip, which can guide the surface scum into the barrel with the water flow, while reducing the probability of scum overflowing from the barrel due to wind and waves. The interior of the filter barrel 31 is provided with a spiral scum-guiding structure, which consists of scum-guiding blades arranged spirally along the inner wall of the barrel. During the reciprocating lifting and lowering of the filter barrel 31, the collected scum gradually moves towards the scum collection area at the bottom of the barrel, facilitating subsequent unified cleaning. The top of the main frame 1 of the equipment is connected to... The bracket is inclined to install photovoltaic solar panels 2, with the sun-receiving surface of the photovoltaic solar panels 2 facing the sun. The top of the main frame 1 of the equipment is also equipped with a waterproof electrical control box, which integrates an energy storage control module and a battery pack. The photovoltaic solar panels 2 are electrically connected to the gas supply drive motor and the thruster 6 through the energy storage control module, which can convert solar energy into electrical energy and store it in the battery pack, enabling long-term autonomous operation without external power grid conditions. The bottom end of the main frame 1 of the equipment is equipped with a thruster 6, which is equipped with a steering adjustment mechanism. By adjusting the thrust direction and output power, the whole machine can be driven to autonomously cruise and move on the water surface, flexibly switching the operating area.
[0023] Working Principle: This equipment floats on the surface of the reservoir using its own buoyancy. The photovoltaic solar panel 2 converts light energy into electrical energy and stores it through the energy storage control module. The thruster 6 at the bottom of the equipment can drive the whole machine to autonomously cruise and move on the water surface by adjusting the thrust output direction and operating power. During the operation of the equipment, the output torque of the air supply drive motor drives the rotating disk 92 to rotate synchronously. At this time, the swing rod 93 swings back and forth in a plane with the disk, thereby pulling the sealing piston to slide back and forth along the inner wall of the fixed cylinder 91. When the sealing piston moves to the air extraction side, the air inlet one-way valve opens and the air outlet one-way valve closes, and the outside air enters the cavity of the fixed cylinder 91 through the air inlet one-way pipe. When the sealing piston moves to the air exhaust side, the air inlet one-way valve closes and the air outlet one-way valve opens, and the compressed air in the cavity is continuously transported to the air storage chamber inside the mounting cover 41 through the connecting pipe 94, thus forming a continuous one-way air supply process. After the compressed air enters the air storage chamber of the mounting cover 41, because the gas density is much lower than that of water, it automatically gathers. A stable air column is formed at the upper part of the cavity. As the air intake continues to accumulate, the height of the air column gradually increases, displacing the water in the cavity downwards. This causes the overall volume of water displaced by the mounting cover 41 to continuously increase. According to Archimedes' principle, the buoyancy of the mounting cover 41 increases linearly with the increase in the volume of water displaced. When the total buoyancy exceeds the total weight of the lifting slider 43, the mounting cover 41, and the microporous aeration disc 7 and other auxiliary components, the lifting slider 43 slowly slides upwards along the vertical guide rail 42, driving the mounting cover 41 and the microporous aeration disc... 7. Simultaneously rising, during the ascent of the lifting slider 43, the gas in the gas storage chamber is continuously transported to the microporous aeration disc 7 through the connecting pipe 10, and released to the surrounding water body in the form of microbubbles, completing the water body oxygenation operation; through the uniform upward rising process, the microporous aeration disc 7 can sequentially oxygenate different depth water layers from the bottom layer, middle layer to the surface layer of the reservoir, break the density barrier of the thermocline layer of the reservoir, promote the exchange of water between the upper and lower water bodies, improve the uniformity of dissolved oxygen in the entire water layer, and improve the problems of bottom anaerobic and bottom sediment pollutant release; When the mounting cover 41 rises to its top travel position, the top of the trigger rod 52 abuts against the bottom end face of the main frame 1 of the equipment. Under downward pressure, the trigger rod 52 slides downward along the through hole at the top of the mounting cover 41, thereby pushing the hinge rod 53 to swing around its central pivot. The other end of the hinge rod 53 drives the adjusting plate 54 to slide radially along the connecting pipe 10, which greatly increases the effective ventilation cross-sectional area of the connecting pipe 10. The compressed air in the air storage chamber flows rapidly through the connecting pipe 10 to the microporous aeration disc 7 and is absorbed in large quantities. Released, at this time the air volume consumption rate in the air chamber is much greater than the air replenishment rate, the air column height drops rapidly, and the volume of water discharged by the installation cover 41 decreases synchronously. The total buoyancy quickly falls below the total weight of the components. The installation cover 41 drives the lifting slider 43 to fall downward along the vertical guide rail 42. During the fall, the microporous aeration disc 7 maintains aeration, forming a reverse convection with the aeration airflow field during the rising stage, further enhancing the water mixing effect and improving the oxygenation uniformity. When the installation cover 41 falls to the lower end of its stroke, the trigger rod 52 loses its resistance pressure. After the spring automatically resets, the adjusting plate 54 returns to its original position synchronously with the hinge rod 53, the ventilation area of the connecting pipe 10 returns to its initial state, and the air storage chamber re-enters the air storage and pressurization stage, continuously achieving full-layer aeration and oxygenation. While the air supply drive motor drives the rotating disk 92, it also drives the connecting shaft 82 to rotate synchronously, causing the incomplete bevel gear 83 at its end to rotate continuously. The incomplete bevel gear 83 alternately meshes with two driven bevel gears 84 symmetrically arranged on the transmission shaft 85. When the incomplete bevel gear... When wheel 83 meshes with one of the driven bevel gears 84, the drive shaft 85 rotates in the forward direction. When it switches to mesh with the other driven bevel gear 84, the drive shaft 85 rotates in the reverse direction. This converts the continuous rotational motion into the reciprocating forward and reverse motion of the drive shaft 85. The drive shaft 85 drives the coaxially fixed rotating shaft 34 to rotate synchronously. At this time, the drive gear 35 swings synchronously. Through the gear and rack meshing transmission, the vertically arranged drive rack 36 is driven to slide up and down along the inner side of the connecting shell 33.The filter bucket 31, suspended by multiple connecting bars 32 at the bottom of the drive rack 36, moves vertically reciprocating in sync. As the filter bucket 31 descends, its top scum inlet cuts into the surface water, carrying algae, fallen leaves, suspended oil, and debris into the bucket. The water is then discharged into the reservoir through evenly distributed permeable filtration holes on the side wall of the bucket. Floating pollutants are trapped inside the bucket. The scum-blocking lip at the edge of the scum inlet reduces the probability of scum escaping in the opposite direction due to wind and waves. A spiral scum guide is installed inside the bucket. The structure guides the collected scum to the bottom of the tank, facilitating subsequent unified cleaning and transportation. When the filter tank 31 moves upward, the scum inlet is lifted off the water surface, and the water remaining in the tank is continuously discharged through the permeable filter holes under gravity, achieving gravity dehydration of the scum, reducing its moisture content, and increasing the storage capacity of a single tank. Simultaneously, the reciprocating motion creates an alternating suction and pushing local flow field in the surrounding surface water, drawing scum from a certain area towards the inlet area, expanding the scum collection radius, and improving scum collection efficiency.

7. The reservoir water purification equipment according to claim 1, characterized in that: A photovoltaic solar panel (2) is installed at the top of the main frame (1) of the equipment. The photovoltaic solar panel (2) is electrically connected to the gas supply drive motor through the energy storage control module. A thruster (6) is provided at the bottom of the main frame (1).
8. The reservoir water purification equipment according to claim 1, characterized in that: The filter barrel (31) has water-permeable filter holes evenly distributed on its side wall. The top of the filter barrel (31) has a scum inlet. The edge of the scum inlet is provided with a scum-blocking lip. The interior of the filter barrel (31) is provided with a spiral scum-guiding structure.
9. A reservoir water purification device according to claim 1, characterized in that: The side of the adjustment plate (54) is provided with a sealing strip. The adjustment plate (54) is slidably arranged along the radial direction of the connecting pipe (10). When the mounting cover (41) rises to the point where the trigger rod (52) abuts against the bottom of the main frame (1) of the equipment, the trigger rod (52) presses down to drive the hinge rod (53) to swing, thereby driving the adjustment plate (54) to slide to increase the effective ventilation area of the connecting pipe (10).
