Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, those skilled in the art can obtain the embodiments without any inventive step in advance, and the embodiments are within the protection scope of the present invention.
It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In the embodiment of the present invention, as shown in fig. 1, the method includes: the floating type solar floating aeration machine comprises a floating barrel 1, a floating body 2, an aeration machine body 3 and a solar photovoltaic system 4, wherein the floating barrel 1 is fixedly connected with the floating body 2, the solar photovoltaic system 4 and the aeration machine body 3 are respectively connected with the floating body 2, and the aeration machine body 3 is connected with the solar photovoltaic system 4.
The float 1 is installed on the body 2 that floats, and the aerator body 3 assembly is on the body 2 that floats, still is provided with the solar photovoltaic system 4 that provides the electric energy for the aerator body 3 on the body 2 that floats. When the device works, the buoy 1 plays a role in changing the buoyancy of the whole device and adjusting the submerging depth of the solar aerator. The floating body 2 floats on the water surface. The aerator body 3 and the solar photovoltaic system 4 move along with the floating body 2. Preferably, the number of the floating barrels 1 is 3-4, the floating barrels are uniformly distributed below the floating body 2 to form an equilateral triangle or a square, and the solar aerator can stably float in a water body.
In an embodiment of the present invention, as shown in fig. 2, the aerator body 3 includes: a main machine 31, an impeller 32, a first pod 33, and a second pod 35. The impeller 32 is connected with the main machine 31 and is positioned above the main machine 31; the first air guide sleeve 33 is connected with the main machine 31, and the impeller 32 is positioned in the inner cavity of the first air guide sleeve 33; the second air guide sleeve 35 is located above the first air guide sleeve 33 and connected with the first air guide sleeve 33, and a first flow passage is formed by a gap between the second air guide sleeve 35 and the first air guide sleeve 33. In this preferred embodiment, the aerator body 3 has two flow channels, one of which is a first flow channel formed by the gap between the second air guide sleeve 35 and the first air guide sleeve 33, and the other is a second flow channel formed by the inner cavity of the second air guide sleeve 35. The water flows out of the first and second flow passages by the action of the impeller 32, and falls after contacting with the air. Through setting up two runners, increased the area of contact of rivers and outside air, improved the mixed effect of water and air.
Preferably, the upper portion of the first pod 33 and the upper portion of the second pod 35 are formed in an inverted bell shape. Preferably, the lower part of the first air guide sleeve 33 is a straight cylinder, and the impeller 32 and the main machine 31 are positioned in the inner cavity of the straight cylinder. More preferably, the bottom end of the straight cylinder is located below the main machine 31. The first air guide sleeve 33 with the structure can ensure that when the solar aerator works, the impeller 32 drives the liquid at the lower part to move upwards, so that the water outside the first air guide sleeve 33 moves downwards, and the oxygen dissolving effect is enhanced through repeated circular flow. When the water flows out of the first flow passage and the second flow passage, the upper portion of the first air guide sleeve 33 and the upper portion of the second air guide sleeve 35 play a role in guiding. The upper parts of the first air guide sleeve 33 and the second air guide sleeve 35 are both arc-shaped, so that the resistance of fluid is reduced, the turbulence of water is reduced, and the stress balance of the aerator and the water surface movement of the solar aerator are ensured.
Preferably, the tip radius of the second pod 35 is greater than the tip radius of the first pod 33. The air guide sleeve with the structure can improve the oxygenation effect of the water body. The top radius of second kuppe 35 is greater than the top radius of first kuppe 33 for when the high-speed rivers that are arranged in first runner flow to the top outer wall of second kuppe 35, change flow direction, the downward flow increases the power that rivers washed into the surface of water, thereby the removal route of extension mixed liquid improves the dissolved oxygen effect of water.
Preferably, the difference between the radius of the top end of the second air guide sleeve 35 and the radius of the top end of the first air guide sleeve 33 is L, and L is 50mm to 150 mm.
Preferably, the buoy 1 is provided with a containing cavity for containing liquid with different weights so as to adjust the external water level between the top end of the impeller 32 and the top end of the second air guide sleeve 35. Thus, the outside water surface submerges the impeller 32, and the water flowing out of the impeller 32 flows into the first flow passage and the second flow passage.
Preferably, the external water level may submerge the top end of the first pod 33, but may not submerge the top end of the second pod 35. Thus, there is a layer of air between the ambient water level and the top of the second pod 35 so that the water flowing from the first flow path can mix with the air. If the external water surface submerges the top end of the second pod 35, the water flowing out of the first flow passage is rarely mixed with air and simply flows in the water body. Because the external water surface is lower than the top end of the second air guide sleeve 35, the water flow flowing out of the second air guide sleeve 35 can be mixed with the external air and then falls into the water body.
Preferably, when the air conditioner is used, the distance between the top end of the second air guide sleeve 35 and the outside water surface is H, and the H is 150 mm-400 mm. The top end of the second air guide sleeve 35 is higher than the external water surface, so that the aeration function of the first flow channel is realized.
In the preferred embodiment, the impeller 32, the first air guide sleeve 33 and the second air guide sleeve 35 are located on the same axis. Thus, water flow is acted by the main machine 31 and the impeller 32, and is sprayed at high speed from bottom to top, so that when the water flow passes through the first flow channel and the second flow channel, the basic stability of equipment can be ensured, and the floating body 2 cannot be moved greatly due to the spraying of the water flow.
As a preferred example, the solar aerator further comprises guide vanes 34, and the guide vanes 34 are connected to the inner wall of the second air guide sleeve 35. The guide vanes 34 reduce the rotational motion of the water flow in the second pod 35, increasing the spray height of the fluid.
Preferably, the vanes 34 extend longitudinally along the inner wall of the second shroud 35. The number of the guide vanes is 2-4.
The working process of the solar aerator of the embodiment is as follows; the assembled solar aerator is placed in water and the weight of the liquid in the buoy 1 is adjusted so that the liquid level is in the proper position between the top end of the impeller 32 and the top end of the second air guide sleeve 35. The solar photovoltaic system 4 is connected, the aerator body 3 is started, and the impeller 32 drives the water flow to move upwards at a high speed. The fluid is distributed into two streams as it passes through the first and second fairings 33, 35. The outer water flow gushes out from the gap (i.e. the first flow passage) between the first air guide sleeve 33 and the second air guide sleeve 35 at a high speed. Because the radius of the top end of the second air guide sleeve 35 is larger than the radius of the top end of the first air guide sleeve 33, and the height of the top end of the second air guide sleeve 35 is higher than that of the top end of the first air guide sleeve 33, splashed water splash is mixed with air around the liquid level, the water splash is prevented from backflushing into the water surface at a high speed through the arc-shaped section of the second air guide sleeve 35 and flows to the middle lower part of the water body, the movement path of the mixed liquid is prolonged, oxygen is dissolved into the water, and the oxygen increasing effect of the middle lower part of. The inner-ring water flow gushes out from the inner cavity (namely the second flow passage) of the second air guide sleeve 35, the guide vane 34 reduces the rotation motion of the water flow, increases the jet height of the fluid, improves the flow in the axial direction of the impeller, mixes with more air and increases the oxygenation effect of the water body. The high-speed rotating aerator impeller continuously drives the liquid in the first air guide sleeve 33 to move upwards, and simultaneously, the liquid outside the first air guide sleeve moves downwards, so that the liquid flows circularly repeatedly, the movement path of the mixed liquid is prolonged, and the dissolved oxygen rate of the water body is increased.
The solar aerator provided by the embodiment of the invention can improve the mixing effect of fluid and air, improve the oxygenation effect of the middle lower part of the water body and effectively improve the self-purification capacity of the water body. In the implementation of the invention, the water inlet depth of the solar aerator is adjusted by adjusting the weight of the liquid contained in the float bowl, the solar photovoltaic system supplies power to the aerator body, the aerator body divides the driven water flow into an inner ring water flow and an outer ring water flow, the inner ring water flow gushes out from the second flow guide cover, and the outer ring water flow gushes out from the gap between the first flow guide cover and the second flow guide cover. The two water flows are contacted with the air, so that the oxygenation effect of the water body is improved.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
