Description

Technical Field

[0001] The invention belongs to the technical field of water body oxygenation, and in particular relates to a solar energy gravity flow negative pressure oxygenation device. Background Art

[0002] Traditional water oxygenation technologies mainly include fountain oxygenation, waterfall oxygenation, Venturi oxygenation, and aeration oxygenation.

[0003] 1. Fountain-style oxygenation: Use a water pump to pump water into the air to form fountain-style water droplets, which come into contact with the air to increase oxygen, then fall back into the receiving water body and diffuse, thereby increasing the oxygen content of the water body; 2. Waterfall-style oxygenation: When water falls from a high place, it will form a high-speed flowing water body under the action of gravity acceleration. During the falling process, it will fully contact with the air to increase oxygen, and finally collide with the receiving water body to form a large number of oxygen-containing water splashes, thereby increasing the oxygen content of the water body; 3. Venturi tube oxygenation: Use the Venturi effect to mix the water flow with the air inhaled by negative pressure and then discharge it into the receiving water body; 4. Aeration oxygenation: Force the acceleration of oxygen transfer to the water body to fully mix the air and water. Among them, fountain-type oxygenation and waterfall-type oxygenation both have the characteristics of simple structure and easy maintenance, but have defects such as low dissolved oxygen, high energy consumption and limited oxygenation water depth; while Venturi tube oxygenation has a higher dissolved oxygen content but high energy consumption, limited oxygenation water depth and loud noise, while aeration oxygenation has a high dissolved oxygen content and unlimited oxygenation water depth but high energy consumption, easy clogging and inconvenient maintenance. Summary of the invention

[0004] Based on the problems mentioned in the above background technology, the present invention provides a solar gravity flow negative pressure oxygenation device to solve the problems of low dissolved oxygen, high energy consumption, limited oxygenation water depth, easy clogging and inconvenient maintenance in the current traditional oxygenation method.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A solar energy gravity flow negative pressure oxygenation device comprises a solar energy component, a water pump and an oxygenation pipe, wherein the solar energy component is electrically connected to the water pump for providing electric energy to the water pump, the oxygenation pipe is connected to the water pump, the oxygenation pipe comprises a water inlet pipe fitting, a water distribution tray and a gravity acceleration pipe, the water distribution tray is located above a water body to be oxygenated, the water inlet pipe fitting is connected to the water pump, the water inlet pipe fitting is connected to the water distribution tray for injecting water into the water distribution tray, the gravity acceleration pipe is connected to the water distribution tray for leading water out of the water distribution tray, the gravity acceleration pipe is connected to an oxygenation component, the oxygenation component is in communication with the inside and outside of the gravity acceleration pipe at the same time, after water is injected into the water distribution tray by the water pump, the water in the water distribution tray falls along the gravity acceleration pipe under the action of gravity, and at the same time the gravity acceleration pipe generates negative pressure, and air is sucked in by the oxygenation component to mix with the water body in the gravity acceleration pipe to form oxygenated water, and the gravity acceleration pipe injects the oxygenated water into the water body to be oxygenated to increase the oxygen content of the water body.

[0007] On the basis of the above technical solution, the present invention also makes the following improvements:

[0008] Furthermore, the oxygenating component includes an oxygenating joint, which is installed on the gravity accelerating tube, an oxygenating cavity is provided in the middle of the oxygenating joint, a flow guide tube is provided in the oxygenating cavity, and an air inlet is provided on the oxygenating joint. When the gravity accelerating tube falls, the water flow is accelerated after passing through the flow guide tube to form negative pressure, and air is sucked in through the air inlet. At the same time, the water flow passing through the flow guide tube forms turbulence, so that the sucked air and the water flow are fully mixed to form dissolved oxygen water containing bubbles.

[0009] Furthermore, the number of the air inlet holes is multiple and they are evenly spaced and distributed on the oxygenation joint, so that air and water can be inhaled from multiple directions for mixing, which is beneficial to the uniformity of the mixing of air and water.

[0010] Furthermore, there are multiple gravity acceleration tubes and they are evenly spaced around the water inlet pipe. By setting multiple gravity acceleration tubes to discharge oxygenated water around, it is beneficial to improve the oxygenation effect.

[0011] Furthermore, the oxygenation pipe also includes a connection plate, the connection plate is provided with a first joint and a second joint, the water inlet pipe includes a first water inlet pipe and a second water inlet pipe, the first water inlet pipe and the second water inlet pipe are connected to the first joint, one end of the second joint is connected to the gravity acceleration pipe, and the other end is connected to a release pipe, and the release pipe is immersed in the water body to be oxygenated. The water inlet pipe is divided into two parts and connected by the connection plate, and the second water inlet pipe of different lengths can be selected according to needs to change the height between the water distribution plate and the water surface to be oxygenated.

[0012] Furthermore, the release pipe is in an arc-shaped structure, and the water outlet from the gravity acceleration pipe is buffered and guided by the arc-shaped release pipe, thereby increasing the diffusion area of ​​the dissolved oxygen water.

[0013] Furthermore, a dissolved oxygen head is installed on the release pipe, and a refinement bucket is arranged inside the dissolved oxygen head. A duckbill release bucket is installed at one end of the dissolved oxygen head. Since high-speed water flow will break into small water droplets after hitting an obstacle, when the high-speed water flow containing bubbles flows from the large-diameter gravity acceleration tube into the small-diameter refinement bucket, dissolved oxygen water with smaller bubbles is formed, which is then released by the duckbill release bucket, which is beneficial to prevent the bubbles from re-merging to produce large bubbles, thereby improving the oxygenation quality.

[0014] Furthermore, the water inlet end of the water pump is connected to a filter head, and the filter head includes a shielding cover and a mesh cover, and the mesh cover is located at the lower part of the shielding cover. Under the action of water pressure, the surrounding water enters through the mesh cover, thereby playing a filtering role and preventing the water pump from being blocked. Since the filtering surface of the mesh cover faces downward and has a large area, the suction force formed on the surrounding water body is small, thereby preventing the formation of strong adsorption and causing the mesh cover to be blocked. Secondly, under the action of gravity, foreign matter with a larger specific gravity attached to the mesh cover will naturally fall off when the water pump stops working, thereby realizing the anti-blocking function. At the same time, arranging the mesh cover below the shielding cover can avoid the problem of debris in the water settling and accumulating on the mesh cover to cause blockage of the filter head.

[0015] Beneficial effects of the present invention:

[0016] The water pump injects water into the water distribution tray through the water inlet pipe. Under the action of gravity, the water in the water distribution tray enters the gravity acceleration tube and falls freely, forming negative pressure at the top of the gravity acceleration tube. Under the action of negative pressure, a large amount of air is sucked in through the oxygenating component and mixed in the gravity acceleration tube to form oxygenated water. The oxygenated water is directly rushed into the lake water along the gravity acceleration tube and mixed with the lake water to increase the oxygen content of the lake water, and the oxygenation capacity is better.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 As shown, a solar gravity flow negative pressure oxygenation device comprises a solar module 1, a water pump 2 and an oxygenation pipe, wherein the solar module 1 is electrically connected to the water pump 2 for providing electric energy to the water pump 2, the oxygenation pipe is connected to the water pump 2, the oxygenation pipe comprises a water inlet pipe, a water distribution tray 5 and a gravity acceleration pipe 61, the water distribution tray 5 is located above the water body to be oxygenated, the water inlet pipe is connected to the water pump 2, the water inlet pipe is connected to the water distribution tray 5 for injecting water into the water distribution tray 5, the gravity acceleration pipe 61 is connected to the water distribution tray 5 for injecting water into the water distribution tray 5, and the gravity acceleration pipe 61 is connected to the water distribution tray 5 for injecting water into the water distribution tray 5. The water distribution tray 5 is an unsealed container, and the gravity acceleration tube 61 is connected to the oxygenating component 8. The oxygenating component 8 is connected to the inside and outside of the gravity acceleration tube 61 at the same time. After water is injected into the water distribution tray 5 by the water pump 2, the water in the water distribution tray 5 falls along the gravity acceleration tube 61 under the action of gravity. At the same time, the gravity acceleration tube 61 generates negative pressure, and the air is sucked in by the oxygenating component 8 and mixed with the water in the gravity acceleration tube 61 to form oxygenated water. The gravity acceleration tube 61 injects the oxygenated water into the water to be oxygenated to increase the oxygen content of the water.

[0027] Specifically, Figure 3 As shown, the oxygenation component 8 includes an oxygenation connector 81, which is installed on the gravity acceleration tube 61. An oxygenation cavity 82 is provided in the middle of the oxygenation connector 81, and a flow guide tube 84 is provided in the oxygenation cavity 82. An air inlet 83 is provided on the oxygenation connector 81. When the oxygenation connector 81 is installed, the gravity acceleration tube 61 is cut off, and then the cut gravity acceleration tube 61 is connected by the oxygenation connector 81. The water flow is accelerated and falls along the gravity acceleration tube 61. As the water flow falls, negative pressure is formed in the gravity acceleration tube 61. Under the action of the negative pressure, the air inlet 83 inhales air and mixes with the water flow to form dissolved oxygen water. There are multiple air inlet holes 83 and they are evenly spaced on the oxygenation connector 81. Air and water can be inhaled and mixed in multiple directions, which is conducive to the uniformity of air and water mixing. In this embodiment, the number of air inlet holes 83 is preferably 8.

[0028] Specifically, to improve the oxygenation effect, there are multiple gravity acceleration tubes 61 that are evenly spaced around the water inlet pipe. In this embodiment, there are four gravity acceleration tubes 61 , and dissolved oxygen water is discharged to the surroundings through the four gravity acceleration tubes 61 .

[0029] Specifically, the oxygenation pipe also includes a connection plate, on which a first joint 41 and a second joint 42 are provided, and the water inlet pipe includes a first water inlet pipe 31 and a second water inlet pipe 32, which are connected to the first joint 41, one end of the second joint 42 is connected to the gravity acceleration tube 61, and the other end is connected to the release tube 62, the release tube 62 is immersed in the water body to be oxygenated, and the water inlet pipe is divided into two parts and connected through the connection plate, and different lengths of the second water inlet pipe 32 and the gravity acceleration tube 61 can be selected according to needs to change the height between the water distribution plate 5 and the water surface to be oxygenated, after the height of the water distribution plate 5 is increased, the water flow speed in the gravity acceleration tube 61 is accelerated, the negative pressure is enhanced, and the volume of inhaled oxygen is increased, which can increase the oxygenation amount. At the same time, when the water flow speed in the gravity acceleration tube 61 is accelerated and enters the water body to be oxygenated, the diffusion area can also be increased accordingly.

[0030] Specifically, the release pipe 62 is an arc-shaped structure, and the water outlet of the gravity acceleration pipe 61 is buffered and guided by the arc-shaped release pipe 62, which is beneficial to increase the diffusion area of ​​the dissolved oxygen water.

[0031] Specifically, Figure 4 As shown, a dissolved oxygen head 7 is installed on the release pipe 62, and a refinement bucket 71 is arranged inside the dissolved oxygen head 7. A duckbill release bucket 9 is installed at one end of the dissolved oxygen head 7. Since high-speed water flow will break into small water droplets after hitting an obstacle, when the high-speed water flow containing bubbles flows from the large-diameter gravity acceleration tube into the small-diameter refinement bucket 71, dissolved oxygen water with smaller bubbles is formed, and then released by the duckbill release bucket 9, which is beneficial to prevent the bubbles from re-merging to produce large bubbles, thereby improving the oxygenation quality.

[0032] Specifically, Figure 1 , Figure 5 As shown, the water inlet end of the water pump 2 is connected to a filter head 21, and the filter head 21 includes a shielding cover 211 and a mesh cover 212, and the mesh cover 212 is located at the lower part of the shielding cover 211. Under the action of water pressure, the surrounding water body enters through the mesh cover 212, thereby playing a filtering role and preventing the water pump from being blocked. Since the filtering surface of the mesh cover 212 faces downward and has a large area, the suction force formed on the surrounding water body is small, thereby preventing the formation of strong adsorption and causing the mesh cover 212 to be blocked. Secondly, under the action of gravity, foreign matter with a large specific gravity attached to the mesh cover 212 will also fall off naturally when the water pump stops working, thereby realizing the anti-blocking function. At the same time, arranging the mesh cover 212 below the shielding cover 211 can avoid the problem of debris in the water settling and accumulating on the mesh cover 212 to cause the filter head 21 to be blocked.

[0033] When in use, the solar panel 1 provides the electric energy required for the water pump 2 to work, and the water pump 2 injects the lake water into the water distribution tray 5 along the first water inlet pipe 31 and the second water inlet pipe 32. Since the gravity acceleration pipe 61 is connected to the water distribution tray 5, the water in the water distribution tray 5 enters the gravity acceleration pipe 61 and falls freely. Under the acceleration of gravity, the water flow speed in the gravity acceleration pipe 61 gradually increases from top to bottom, so that negative pressure is formed in the gravity acceleration pipe 61. Since the oxygenating member 8 is connected to the inside and outside of the gravity acceleration pipe 61 at the same time, the air is sucked in through the air inlet pipe under the action of negative pressure and mixed with the water in the gravity acceleration pipe 61 to form dissolved oxygen water. Finally, the dissolved oxygen water is filled into the lake water along the release pipe 62 to achieve the purpose of oxygenation.
