Description

Technical Field

[0001] The present invention relates to the technical field of river ecological restoration, and in particular to a mobile oxygenation platform for river ecological restoration. Background Art

[0002] A notable characteristic of river ecosystems is their strong self-purification capacity. Environmental changes and species succession foster a well-balanced interspecies relationship, resulting in structural integrity and efficient function. When one part of the system malfunctions, it can be offset by adjustments in other parts. Human interference is a major factor in ecological damage. In areas with dense human activity along river banks, overuse of the river, and the discharge of large amounts of sewage cause ecosystem degradation and damage, disrupting the river's self-purification capacity.

[0003] At this time, artificial restoration of the river ecosystem is necessary. One method is river aeration. This involves artificially injecting air or oxygen into the water to accelerate the reoxygenation process, thereby increasing the dissolved oxygen level in the water, repairing and enhancing the vitality of aerobic microorganisms in the water, and promoting the degradation of organic pollutants. This improves the water quality of the polluted water and, in turn, restores the water ecosystem. Based on the engineering practices of river aeration both domestically and internationally, applying river aeration technology at different times of river water quality change can eliminate black and odorous water, reduce the pollution load on the water, and promote the recovery of the river ecosystem.

[0004] River aeration and reoxygenation generally take the form of fixed oxygenation stations and mobile oxygenation platforms. Fixed oxygenation stations include air aeration: a fixed blower room is set up on the river bank, which introduces air or oxygen through pipes into the aeration and diffusion system installed at the bottom of the river to increase the dissolved oxygen in the water. This type of aeration generally consists of a machine room (with a built-in blower), air diffusers, and related piping. Mechanical aeration: Mechanical aeration equipment (mostly buoy-type structures) is fixed directly in the river to aerate the water to increase the dissolved oxygen in the water. It also comes in two forms: impeller suction and push flow aerators; underwater jet aerators.

[0005] Since the existing mobile oxygenation equipment moves by rotating the impeller, the impeller is easily caught in aquatic plants during movement, affecting the movement of the equipment. In addition, during oxygenation, only external gas can be injected into the water, and the oxygenation method is single. Therefore, a mobile oxygenation platform for river ecological restoration is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0033] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0034] The present invention provides a mobile oxygenation platform for river ecological restoration. When the piston rod is driven upward, gas enters the one-way exhaust pipe through the one-way air inlet pipe. When the piston rod is driven downward, the gas in the one-way exhaust pipe is discharged into the water. The reaction force of the exhaust gas is used to move the mobile platform on the water surface, forming a pneumatic propulsion effect. The mobile platform can fill air into the water for oxygenation while moving, thereby increasing the oxygenation method and ensuring the oxygenation effect. Figure 1-Figure 5 , including: a mobile platform 100 and a driving mechanism 200.

[0035] The mobile platform 100 includes a support plate 110, a buoy 120, a bracket 130, a one-way exhaust pipe 140, and a one-way air intake pipe 150. The buoys 120 are provided on both sides of the support plate 110, the bracket 130 is provided on the support plate 110, the one-way exhaust pipe 140 is provided on both sides of the front end of the support plate 110, and the one-way air intake pipe 150 is provided on the one-way exhaust pipe 140.

[0036] Among them, when the buoy 120 floats, the lower end of the one-way exhaust pipe 140 is located below the water surface, the support plate 110 is located above the water surface, the buoys 120 are symmetrically arranged on both sides of the support plate 110, and the bracket 130 is erected to provide support for the equipment. The one-way exhaust pipe 140 adopts an L structure, with the upper end vertically upward and the lower end horizontally facing the tail side of the buoy 120. The lower part of the one-way exhaust pipe 140 is arranged parallel to the buoy 120 to reduce the water resistance during movement. The gas enters the one-way exhaust pipe 140 in one direction from the one-way air inlet pipe 150, and is then discharged in one direction from the tail end of the one-way exhaust pipe 140. At the same time, no impeller drive is required to avoid the impeller being drawn into the water tank and affecting movement.

[0037] The driving mechanism 200 is arranged on the bracket 130, and the driving mechanism 200 includes a support shaft 210, a transmission bevel gear 220, a driving component 230, a driving bevel gear 240, a driving disk 250, a driving eccentric shaft 251, a driving rocker 260, a driving piston rod 270, a movable connecting seat 280 and a driving piston 290. The support shaft 210 is rotatably connected to the upper end of the bracket 130, the transmission bevel gear 220 is arranged on the support shaft 210, and the driving component 230 is fixed on the bracket 130. A driving bevel gear 240 meshing with the transmission bevel gear 220 is provided at the output end of the component 230. A driving disk 250 is provided at both ends of the support shaft 210. A driving eccentric shaft 251 is provided on the outer end surface of the driving disk 250. A driving rocker arm 260 is hingedly connected to the driving eccentric shaft 251. A driving piston rod 270 is slidably connected to the upper end of the one-way exhaust pipe 140. A movable connecting seat 280 connected to the driving rocker arm 260 is provided at the upper end of the driving piston rod 270. A driving piston 290 is provided at the lower end of the driving piston rod 270.

[0038] Among them, the driving component 230 adopts a waterproof motor, the driving component 230 drives the driving bevel gear 240 to rotate, the driving bevel gear 240 drives the transmission bevel gear 220 to rotate, the transmission bevel gear 220 drives the driving disk 250 to rotate through the support shaft 210, the driving disk 250 drives the driving eccentric shaft 251 to move in a circle, and the driving eccentric shaft 251 drives the driving piston rod 270 to move up and down through the driving rocker 260. When the driving piston rod 270 moves upward, the gas enters the one-way exhaust pipe 140 through the one-way air inlet pipe 150. When the driving piston rod 270 moves downward, the gas in the one-way exhaust pipe 140 is discharged into the water, and the reaction force of the exhaust is used to cause the mobile platform 100 to move on the water surface.

[0039] Since the above-mentioned mobile oxygenation method can only fill gas into water, the contact range between water and air is limited. Therefore, a spraying mechanism 300 is provided on both sides of the support plate 110. The spraying mechanism 300 includes a water supply pipe 310, a drainage pipe 320, a rotating nozzle 330 and a one-way valve 340. The water supply pipe 310 is fixed on both sides of the support plate 110. The top of the side wall of the water supply pipe 310 is connected to the drainage pipe 320. The upper end of the drainage pipe 320 is connected to the rotating nozzle 330. The lower end of the water supply pipe 310 is provided with a one-way valve 340. A water supply mechanism 400 is connected between the water supply pipe 310 and the movable connecting seat 280.

[0040] The water supply mechanism 400 draws water from the river, and the water flows upward from the water supply pipe 310, passes through the drainage pipe 320 and the rotating nozzle 330, and is sprayed into the air, so that the water and the air are fully in contact and oxygenated.

[0041] Specifically, the water supply mechanism 400 includes a column 410, a lever shaft 420, a lever 430, a strip groove 440, a water supply piston rod 450 and a water supply piston 460. The column 410 is fixed to both sides of the support plate 110. The lever shaft 420 is provided at the upper end of the column 410. The lever 430 is connected to the lever shaft 420 through the strip groove 440. One end of the lever 430 is hinged to the movable connection seat 280. The other end of the lever 430 is movably connected to the water supply piston rod 450 through the strip groove 440. The water supply piston rod 450 is connected to the water supply pipe 310. The lower end of the water supply piston rod 450 is provided with a water supply piston 460 located in the water supply pipe 310.

[0042] Among them, the movable connecting seat 280 moves up and down following the driving piston rod 270. When the movable connecting seat 280 moves up and down, the water supply piston rod 450 is driven to move up and down through the lever 430. The water supply piston rod 450 and the water supply pipe 310 form the structure of a traditional water pressure well, which draws water from the river and discharges the water from the river from the water supply pipe 310, the drainage pipe 320 and the rotating nozzle 330. When supplying water, the one-way valve 340 ensures that the water flows in one direction upward to prevent water backflow.

[0043] Since the water supply pipe 310 is longer when pumping water, it is necessary to expand the activity of the water supply piston rod 450. To this end, the lever 430 at one end of the movable connecting seat 280 has a shorter lever arm length than the other end. When the swing amplitude of one end of the movable connecting seat 280 is smaller, the water supply piston rod 450 can obtain a larger activity amplitude, thereby achieving the effect of expanding the formation.

[0044] Since there may be obstacles at the bottom of the water, the hard water supply pipe 310 may be easily blocked by the obstacles, thus affecting the forward movement. Therefore, a bellows 350 is provided on the water supply pipe 310. The bellows 350 is located below the one-way valve 340, so that the water supply pipe 310 can bend over the obstacles to avoid being blocked when the mobile platform 100 moves.

[0045] Since there will be a lot of floating objects on the static water surface, which will affect the movement of the mobile platform 100, a fishing mechanism 500 is provided at the front end of the support plate 110. The fishing mechanism 500 includes a collecting bucket 510, a movable groove 520, a rotating frame 530, a fishing shaft 540, a tough rake tooth 550, a driven disk 560, a driven eccentric shaft 561, a fixed rod 570 and a driven rocker rod 580. The collecting bucket 510 is fixed at the front end of the support plate 110, and the front end of the collecting bucket 510 is evenly opened. The movable grooves 520 are distributed, and rotating frames 530 are set on both sides of the front end of the collecting barrel 510. A fishing shaft 540 is set on the rotating frame 530. The fishing shaft 540 is evenly distributed with tough rake teeth 550. Driven disks 560 are set at both ends of the fishing shaft 540. Driven eccentric shafts 561 are set on the driven disks 560. A fixed rod 570 is fixed to the upper end of the water supply piston rod 450. The other end of the fixed rod 570 is connected to the driven eccentric shaft 561 through a driven swing rod 580.

[0046] Among them, when the water supply piston rod 450 moves up and down, it drives the fixed rod 570 to move up and down, and the fixed rod 570 drives the driven disk 560 to rotate in a circle through the driven rocker rod 580. The driven disk 560 drives the fishing shaft 540 to rotate in a circle, and the fishing shaft 540 drives the tough rake teeth 550 to rotate on the water surface, and the floating objects on the water surface are picked up. The picked up floating objects are brought into the collection bucket 510 by the rotating tough rake teeth 550, and the tough rake teeth 550 pass through the movable groove 520. The floating objects are blocked in the collection bucket 510 and collected. The tough rake teeth 550 can be deformed. When the floating objects block the rotation of the tough rake teeth 550, they can deform and pass over the floating objects. When the tough rake teeth 550 rotate, they can break the water surface and mix the water on the water surface with the air for aeration.

[0047] Since floating objects may enter between the tough rake teeth 550 and the buoy 120 and cause blockage, a paddle 581 is fixedly provided at the lower end of the driven rocker arm 580. The paddle 581 is tiltedly arranged on the driven rocker arm 580. The paddle 581 follows the lower end of the driven rocker arm 580 in a circular motion on the driven disk 560. The movable paddle 581 is used to push away the floating objects between the tough rake teeth 550 and the buoy 120, so that the floating objects enter the tough rake teeth 550 for processing.

[0048] In order to prevent underwater garbage from entering the water supply pipe 310, a filter screen is provided at the lower end of the water supply pipe 310. The filter screen is screwed to the lower end of the water supply pipe 310 to screen the underwater garbage.

[0049] During specific use, the driving component 230 drives the driving bevel gear 240 to rotate, the driving bevel gear 240 drives the transmission bevel gear 220 to rotate, the transmission bevel gear 220 drives the driving disc 250 to rotate through the support shaft 210, the driving disc 250 drives the driving eccentric shaft 251 to move in a circular motion, and the driving eccentric shaft 251 drives the driving piston rod 270 to move up and down through the driving rocker 260. When the driving piston rod 270 moves upward, the gas enters the one-way exhaust pipe 140 through the one-way intake pipe 150. When the driving piston rod 270 moves downward, the one-way exhaust pipe 1 The gas in 40 is discharged into the water, and the reaction force of the exhaust gas is used to make the mobile platform 100 move on the water surface, forming a pneumatic propulsion effect, so that the mobile platform 110 can fill the water with air to oxygenate while moving, thereby increasing the oxygenation method and ensuring the oxygenation effect. The movable connecting seat 280 moves up and down following the driving piston rod 270. When the movable connecting seat 280 moves up and down, the lever 430 drives the water supply piston rod 450 to move up and down. The water supply piston rod 450 and the water supply pipe 310 form a traditional water pressure well structure to extract water from the river. The water is discharged from the water pipe 310, the drainage pipe 320 and the rotating nozzle 330 and sprayed into the air so that the water and the air are fully in contact and oxygenated. When the water supply piston rod 450 moves up and down, it drives the fixed rod 570 to move up and down. The fixed rod 570 drives the driven disk 560 to rotate in a circle through the driven swing rod 580. The driven disk 560 drives the fishing shaft 540 to rotate in a circle. The fishing shaft 540 drives the tough rake teeth 550 to rotate on the water surface to pick up floating objects on the water surface. The picked-up floating objects are brought into the collection bucket 510 by the rotating tough rake teeth 550. The tough rake teeth 550 are pulled out from the movable groove 52 0, the floating objects are intercepted in the collection bucket 510 and collected. The flexible rake teeth 550 can be deformed. When the floating objects block the rotation of the flexible rake teeth 550, the flexible rake teeth 550 can be deformed to pass over the floating objects. At the same time, the rotating flexible rake teeth 550 can push the water surface away, so that the water on the water surface contacts the air and is oxygenated. The paddle plate 581 follows the lower end of the driven rocker rod 580 in a circular motion on the driven disk 560. The movable paddle plate 581 is used to push away the floating objects between the flexible rake teeth 550 and the buoy 120, so that the floating objects enter the flexible rake teeth 550 for processing.

[0050] In addition, the front end of the support plate 110 is connected to the bracket 130, while the rear is left empty, so that aeration equipment can be installed at the rear. Combined with the one-way exhaust pipe 140 for exhaust and oxygenation, the rotating nozzle 330 for spraying aeration and the tough rake teeth 550 for water breaking aeration of the oxygenation platform, a variety of oxygenation and aeration methods can be achieved to improve the oxygenation effect.

[0051] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
