SOLAR MOVING DEVICE FOR SILT OXIDIZATION, DECOMPOSITION, LU102775

AERATION AND OXYGENATION BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The invention relates to a solar power-expansion moving device for silt oxidization, decomposition, aeration and oxygenation, belonging to the technical field of fishery machinery and equipment.

[0003] Description of Related Art

[0004] China has a vast area of water, but lakes, river channels and ponds are extensively contaminated. Tree leaves, dead aquatic plants and anthropogenic waste in the nature, as well as residual feeds, faeces and other sediments from pond culture release numerous organic matters including NH3 and H2S. These organic matters are dissolved | into water to make the water stink, and a large number of silt is produced at the bottom. For this reason, both the ecology and the aquaculture industry are troubled, affecting the ecological environment with green mountains and rivers.

[0005] The existing methods for treating bottom silt include silt suction, excavation, dry pond exposure and water oxygenation. Desilting and dry pond exposure methods are high in treatment cost and long in period. To be specific, for the desilting method, silt stacking is required to greatly affect the culture benefit. But aerators are generally arranged in the water for oxygenation, which has an unsatisfactory oxidation effect on the silt at the bottom surface, especially affects the scenery of scenic spot.

[0006] The above pond aerators include impeller, ploughing, water wave making and aeration oxygenation devices, all of which are arranged at fixed spots for oxygenation. Hence, the oxygen dissolution in the large-area water has the spot limitation and little effect. Although various aerators have high oxygenation efficiency in the water, the aerators cannot oxidize and decompose the bottom silt. The aerators may be arranged at LU102775 the bottom for aeration to exchange bottom water with upper water, but have a small exchange capacity of the water.

[0007] The existing aeration and oxygenation have some shortages, and the aeration has an unsatisfactory exchange capacity between the upper and lower water. Moreover, the aeration devices placed at the fixed spots have limitations on oxygen dissolution in the water, for example, the oxygen contents in the water are greatly different and the aeration and oxygenation efficiency is low. Hence, the existing aeration and oxygenation devices are certainly limited during use.

[0008] The water degradation is caused by a large number of silt accumulated at the bottom layer. The silt must be decomposed to improve the water quality. A good method to decompose the silt is to repeatedly plough and oxidize the bottom silt. The aerator is placed at the bottom to exchange the bottom with the upper water for aeration, but has a small exchange capacity between the bottom layer and the upper water. Besides, compared with the fixed aeration, the movable aeration will improve the dissolved oxygen in the water. Nevertheless, the difficulties are how to provide the moving power and how to make the aeration part always close to the bottom of river channel while implementing the movable aeration.

[0015] The invention has the following beneficial effects:

[0016] 1) The movable aeration is implemented, and the moving power of the float is from aeration. The exchange capacity between the bottom layer and the upper water by the aeration is improved; the upper and lower water is exchanged and mixed with the water surface, which may volatilize volatile hazardous substances, NH3, H2S and so on from the water. Compared with the method of aeration and oxygenation arranged at fixed points, the movable aeration and oxygenation method raises 50% of dissolved oxygen in the water. The aeration in the diversion pipe forms pumping such that the silt is oxidized and decomposed in the diversion pipes and then delivered to the water surface for exchange and mixture with the upper water, in order to volatilize volatile the hazardous substances, NH3, H2S and so on from the silt. Meanwhile, the bottom water is mixed with | the algae on the water surface in the aeration, and algae absorb the hazardous substances | from water and release oxygen to improve the dissolved oxygen content in the water third LU102775 time under the photosynthesis of sunlight.

[0017] 2) The aeration location is always close to the bottom of the river channel by virtue of floating the diversion pipes up and down; the silt at the bottom layer and the water surface are mixed by the aeration, algae absorb hazardous substances from the water and release oxygen under the photosynthesis of sunlight, thus improving a dissolved oxygen content in the water.

[0018] 3) The cover part is kept in a balanced state by the aeration thrust, and the buoys are driven to move forwards by stroking power caused by the upwarp of the tail board part due to sinking of the cover part after releasing pressure, which solves the moving power problem; the aeration is taken as the power actually without additional power, which solves an actual problem that the capability of generating power by the solar energy is insufficient.

[0019] 4) The problem of moving the float back and forth is solved; the diversion pipes may float freely under the limitation of the longitudinal channel, and have two functions: firstly, the aeration location is always adjacent to the bottom of the river channel; secondly, the problem of controlling the float to move back and forth is solved: according to the bottom height changes of the river channel, the diversion pipes float up and down to trigger the limit switch, and drive the funny fish and the diversion cylinder to integrally rotate 180° in the horizontal plane by the reversing power unit so that the buoys 16 are ready to move forwards reversely, thereby solving the problem of controlling the float to move back and forth by pure machinery easily and reliably.

[0020] 5) The aeration in the diversion pipes forms pumping to increase the water lifting exchange capacity, which is about 5 times higher than that of the water pump. However, this will cause that the diversion pipes are unable to move because they get stuck in the silt while moving in the silt due to the aeration counter force, which is solved ingeniously by providing the buoyant silt sleds; moreover, the buoyant silt sleds are LU102775 designed such that the heads thereof lean forwards but the tails thereof lean backwards, front inclined surfaces of the front ends are beneficial for the obstacle at the bottom of the river channel to form an upward component force on the diversion pipes; in addition, the buoyancy on the buoyant silt sleds may reduce the overall weight of the diversion pipes and increase a contact surface area with the silt to slide freely in the silt, and a rear inclined surface of the rear end allows the buoyant silt sleds to move forwards only but not to move backwards while moving in the silt.

[0021] 6) The whole device is smart in design and is interested by virtue of using the solar energy as the power. Due to small matching power on the moving float, the hollow semi-spherical fish head of the funny fish is used for collecting the waste gas after being subject to aeration and oxygenation to sink and float, the fish tail bobs up and down on the water surface to poke water along with the fish head, and then regenerates power to make waves for oxygenation on the water surface, so that the dissolved oxygen content in the water may be improved the second time. It is especially applicable to parks or scenic spots.

[0022] 7) The diversion pipes are provided with double bushings, the double bushings may slide on the rotary shafts and the support shaft in the bottom hollows, thereby preventing the buoyant silt sleds from grounding in the muddy ground of the hollow; and in case of shoals at both banks, the limit switch on the support shaft controls the float to move reversely.

[0023] 8) The air pump is connected to the reversing valve to the conversion thrust cylinder to the reversing valves to the aeration rings, the compressed air enters the aeration rings for aeration through the conversion thrust cylinder after the conversion thrust cylinder is subject to backward and forward movement conversion. Auxiliary power is not needed in this course.

[0042] Referring to Figs. 1a-5b, the compressed air of the air pump 2 enters a reversing valve 11, and the reversing valve 11 is connected to an air inlet A 10a and an air inlet B 10b; the compressed air enters a conversion thrust cylinder 10, an air outlet A 10c and an air outlet B 10d are connected to a reversing valve 12 connected to the aeration rings 22, and the limit switch 18 controls the reversing valve 11 and the reversing valve 12.

[0044] In practical work, referring to Figs. la-7, according to a solar moving device for silt oxidization, decomposition, aeration and oxygenation, a float is composed of a float beam 14 connected with two buoys 16, a solar panel 1 and a rope guide pipe 17 are erected above the two buoys 16, a rope is inserted into the rope guide pipe 17 and both ends of the rope are secured at both banks; the float may move in the rope between the both banks, and the air pump 2 is arranged on the solar panel 1; when the sun rises to illuminate the solar panel 1, the solar panel 1 generates current to start the air pump 2 that LU102775 communicates with a reversing valve 11, and the reversing valve 11 communicates with an air inlet A 10a; compressed air enters the conversion thrust cylinder 10, the air inlet B 10b is closed; the air outlet B 10d communicates with the reversing valve 12, the air outlet A 10c is closed; the reversing valve 12 communicates with the aeration rings 22, the compressed air enters the aeration rings 22 erected in the lower orifices of the diversion pipes 21; the aeration rings 22 carry out aeration and oxygenation at the bottom layer in the diversion pipes 21, and the limit switch 18 controls the reversing valves 11 and 12;

The water at the bottom of pond is mixed with the water surface by the aeration, and algae absorb the hazardous substances from water and release oxygen under the photosynthesis of sunlight; The water lifting flow of the aeration in the pipes is higher than the pumping flow of the water pump by more than 5 times, so that the oxygen content in the water is improved and the silt is fully oxidized and decomposed.

Compared with the method of aeration and oxygenation arranged at fixed points, the movable aeration and oxygenation method raises 50% of dissolved oxygen in the water. The aeration in the diversion pipe forms pumping such that the silt is oxidized and decomposed in the diversion pipes and then delivered to the water surface for exchange and mixture with the upper water, in order to volatilize volatile the hazardous substances, NH3, H2S and so on from the silt. Meanwhile, the bottom water is mixed with the algae on the water surface in the aeration, and algae absorb the hazardous substances from water and release oxygen to improve the dissolved oxygen content in the water third time under the photosynthesis of sunlight. The aeration location is always close to the bottom of the river channel by virtue of floating the diversion pipes up and down; the silt at the bottom layer and the water surface are mixed by the aeration, algae absorb hazardous substances from the water and release oxygen under the photosynthesis of sunlight, thus improving a dissolved oxygen content in the water. The cover part is kept in a balanced state by the aeration thrust, and the buoys are driven to move forwards by stroking power caused by the upwarp of the tail board part due to sinking of the cover part after releasing pressure, which solves the moving power problem; the aeration is taken as the power actually without additional power, which solves an actual problem that the capability of generating power by the solar energy is insufficient. The problem of moving the float back and forth is solved; the diversion pipes may float freely under the limitation of the longitudinal channel, and have two functions:

firstly, the aeration location is always adjacent to the bottom of the river channel; secondly, LU102775 the problem of controlling the float to move back and forth is solved: according to the bottom height changes of the river channel, the diversion pipes float up and down to trigger the limit switch, and drive the funny fish and the diversion cylinder to integrally rotate 180° in the horizontal plane by the reversing power unit so that the buoys 16 are ready to move forwards reversely, thereby solving the problem of controlling the float to move back and forth by pure machinery easily and reliably.

The aeration in the diversion pipes forms pumping to increase the water lifting exchange capacity, which is about 5 times higher than that of the water pump.

However, this will cause that the diversion pipes are unable to move because they get stuck in the silt while moving in the silt due to the aeration counter force, which is solved ingeniously by providing the buoyant silt sleds; moreover, the buoyant silt sleds are designed such that the heads thereof lean forwards but the tails thereof lean backwards, front inclined surfaces of the front ends are beneficial for the obstacle at the bottom of the river channel to form an upward component force on the diversion pipes; in addition, the buoyancy on the buoyant silt sleds may reduce the overall weight of the diversion pipes and increase a contact surface area with the silt to slide freely in the silt, and a rear inclined surface of the rear end allows the buoyant silt sleds to move forwards only but not to move backwards while moving in the silt.

What is claimed is: LU102775

1. A solar moving device for silt oxidization, decomposition, aeration and oxygenation, comprising diversion pipes (21), a cover part, buoys (16) and a reversing power unit; the cover part comprises a cap-shaped part and a tail board part connected transversely thereof, and the cap-shaped part is covered above the diversion pipes (21) and rotatably fixed on a horizontal rotary shaft; the cap-shaped part is heavier than the tail board part so | that the cap-shaped part sinks but the tail board part upwarps in a natural state; at least a pair of diversion pipes (21) is located at both sides of the buoys (16), the bottom of each diversion pipe (21) is fixedly connected to a buoyant silt sled (23), and an aeration ring (22) is fixedly arranged at an interior bottom of each diversion pipe (21); a buoyancy of the cap-shaped part and the tail board part are kept in a balanced state by the aeration produced by the aeration rings (22), namely, when the cap-shaped part releases air pressure, the cap-shaped part sinks but the tail board part upwarps and strokes so that the | buoys (16) move forwards; the reversing power unit is connected to the diversion pipes (21) and the cover part; each diversion pipe (21) is limited in a longitudinal channel by a rotary shaftrotary shaft (19), and the top of the longitudinal channel is provided with a limit switch (18); when the bottom of a river channel uplifts to lift the diversion pipes (21) to trigger the limit switch (18), the reversing power unit drives the cover part and the diversion pipes (21) to rotate 180° so that the buoys (16) are ready to move forwards reversely.

2. The solar moving device for silt oxidization, decomposition, aeration and oxygenation according to Claim 1, wherein the cover part is a funny fish device (4), the cap-shaped part is a fish head, and the tail board part is a fish body and a fish tail; the fish head is a hollow hemisphere reversed on a water surface, a gravity ball (3) is tilted in front of the head, and a vent valve (5) is arranged at the top of the fish head; the fish tail is composed of three inclined boards and is of small top and big bottom, the fish head and the fish tail are connected to form the fish body by a square pipe, and a lug orifice plate (6) LU402775 is arranged in the middle of the fish body; a limit plate is arranged on the square pipe of the fish body in front of and behind the lug orifice plate (6), and the lug orifice plate (6) is | a fulcrum for the funny fish device (4) to rotate up and down; after waste gas subject to | aeration and oxygenation is collected into the fish head of the funny fish (4), the fish head filled with air floats but the fish tail sinks; after the vent valve (5) in the fish head vents, the fish head sinks, especially the fish head sinks rapidly under an action of gravity of the gravity ball (3) to accelerate an upturning moment of the fish tail, and the water is rippled by the fish tail, so that a water wave surface area increases to cause water wave oxygenation, and meanwhile the fish tail raises a counter force to push the float to move.

3. The solar moving device for silt oxidization, decomposition, aeration and oxygenation according to Claim 2, wherein a solar panel (1) and a rope guide pipe (17) are erected above a pair of buoys (16), an air pump (2) is arranged below the solar panel (1), stay bars (15) are fixed at both middle sides of an I beam (14) and circular casings are uprightly arranged at both ends of the stay bars (15); the top end of each rotary shaftrotary shaft (19) is provided with a rotary lug orifice, a limiter (7) is arranged below the rotary lug orifice, and a belt pulley (8) is fixed in the middle of each rotary shaftrotary shaft (19); the rotary shaftrotary shafts (19) are inserted into the circular casings of the stay bars (15), lower front ends of the rotary shaftrotary shafts (19) are fixed with a support shaft (20a), the rotary shaftrotary shafts (19) are parallel to the support shaft (20a) and the upper parts of the diversion pipes (21) are fixed with double sliding sleeves (20); the double sliding sleeves (20) are sleeved on the rotary shaftrotary shafts (19) and the support shaft (20a), upper orifices of the diversion pipes (21) are reversed into the fish head of the funny fish (4) on the water surface, and the double sliding sleeves (20) maymove up and down between the rotary shaftrotary shafts (19) and the support shaft (20a); the top of the support shaft (20a) is provided with the limit switch (18), baffles are arranged at the top of the support shaft corresponding to the double sliding sleeves (20), the aeration rings (22) LU102775 are erected in the lower orifices of the diversion pipes (21), the buoyant silt sleds (23) are arranged at both outer sides of the lower orifices of the diversion pipes (21), and heads of the buoyant silt sleds (23) lean forwards and tails thereof lean backwards so that the buoyant silt sleds (23) may only move forwards but cannot move backwards in the silt; the buoyant silt sleds (23) reduce the overall weight of the diversion pipes to prevent the | diversion pipes from being unable to move due to the fact that the overweight diversion pipes get stuck in the silt, and meanwhile alleviate a friction force caused by the movement of the buoyant silt sleds (23) in the silt.
