Description

Technical Field

[0001] The present invention relates to river environment restoration technology, and specifically to a device for restoring the ecological environment of a river. Background Art

[0002] In the field of microbial restoration of river waters, there are currently two common restoration methods. One is that personnel board a hull on the water body, manually stir the microbial stock solution and water, and then sprinkle the microbial mixture into the water body through tools; the other method is to remotely control and drive a mobile carrier equipped with a spraying function to effectively spread the solution over a designated water area. In the prior art, an alternating use method of two medicine barrels is adopted to increase the spraying range. However, when the stock solution in the barrel is used up, it is still necessary to go to the shore for filling, which is rather troublesome.

[0003] Chinese Patent with Application No. 202311668064.4 discloses a device for restoring the ecological environment of a river. By setting a mixing barrel and a mixing component, secondary premixing is carried out in the mixing barrel and the mixing component. And during the second mixing, by connecting and isolating multiple second mixing chambers, the multiple second mixing chambers independently mix the liquid medicine, which can improve the mixing uniformity. The uniformly mixed liquid medicine is directly put into the environmental water body after being mixed with the base. The device for restoring the ecological environment of a river can automatically complete the mixing and feeding work through remote control, which is convenient to operate. However, there are still some problems in the implementation process of this device. During the implementation process of this patent, the aerobic bacteria of the microorganisms cannot make full contact reaction with the river water, resulting in a poor purification effect on the river water. At the same time, directly putting the aerobic bacteria of the microorganisms into the river water causes some problems. When the aerobic bacteria of the microorganisms enter the river water, they will be impacted by the flow of the river water, and at the same time, there is no attachment for the aerobic bacteria of the microorganisms to adhere to, making the aerobic bacteria of the microorganisms unable to adapt to the water environment and unable to reproduce further. As a result, some aerobic bacteria of the microorganisms lose their activity in the flow of the river water, leading to a poor effect of the aerobic bacteria of the microorganisms on purifying and treating the river water.

An installation pipe 2 is rotatably connected to the installation plate 1. A plurality of filter boxes 3 are fixedly connected to the outer surface of the installation pipe 2. A filter culture box 4 fixedly connected to the installation pipe 2 is arranged inside the filter box 3. A plurality of culture pipes 5 rotatably connected to the installation pipe 2 are rotatably connected inside the filter culture box 4. The outer surface of the installation pipe 2 is drivingly connected to a first driving mechanism connected to the installation plate 1. The first driving mechanism is used to drive the installation pipe 2 to rotate. A fixed column is fixedly connected to the bottom of the installation plate 1;

[0034] A strain culture and filtration mechanism connected to the installation pipe 2 is arranged on the outer surface of the culture pipe 5. The strain culture and filtration mechanism is used to culture strains and biologically purify river sewage;

[0035] A cleaning mechanism connected to the strain culture and filtration mechanism is arranged between the filter box 3 and the filter culture box 4. The cleaning mechanism is used to clean the filter box 3 and the filter culture box 4.

[0036] The first driving mechanism includes a first driving motor 51 fixedly connected to the mounting plate 1.

[0037] By inserting the mounting posts on the mounting plate 1 into the river channel for fixation, and then driving the mounting pipe 2 to rotate through the first driving mechanism, the two filter frames 3 and the filter culture frame 4 are rotated to be perpendicular to the flowing direction of the river surface. Then, the filter frames 3 and the filter culture frame 4 filter and purify the water flowing in the river channel.

The second drive mechanism is used to drive the first drive shaft 21 and the second drive shaft 22 to rotate;

[0042] The second drive mechanism includes a second drive motor 31 fixedly connected to the mounting pipe 2. The second drive motor 31 is controlled by a PLC programming program, which can control the second drive motor 31 to rotate forward and backward and the rotation angle. The output end of the second drive motor 31 is fixedly connected to a second drive shaft 32 through a coupling. A third drive gear 33 is fixedly sleeved on the outer surface of the second drive shaft 32.

The second drive motor 31 drives the second drive shaft 32 to rotate, and the second drive shaft 32 drives the first drive shaft 21 and the second drive shaft 22 to rotate through the third drive gear 33 and the fourth drive gear 34;

[0043] The feeding mechanism includes a first feeding pipe 41 fixedly connected to the mounting pipe 2. A second feeding pipe 42 is fixedly connected to the outer surface of the first feeding pipe 41. An electromagnetic valve is arranged on the second feeding pipe 42. Two first connecting pipes 43 are fixedly connected to the outer surface of the second feeding pipe 42. One end of the first connecting pipe 43 is fixedly connected to a second connecting pipe 44 rotatably connected to the culture pipe 5. The top end of the first feeding pipe 41 is rotatably connected to a third connecting pipe 45 fixedly connected to the mounting pipe 2. An air pump 46 is fixedly connected to the outer surface of the third connecting pipe 45 through a pipeline. An electromagnetic valve is arranged on the pipeline. A water pump 47 is fixedly connected to the outer surface of the third connecting pipe 45 through a pipeline. The input end of the water pump 47 is fixedly connected to a feeding tank 48 fixedly connected to the mounting plate 1. When it is necessary to supply an aerobic bacteria solution into the culture pipe 5, at this time, the electromagnetic valve on the pipeline of the air pump 46 is closed, and the electromagnetic valve on the pipeline of the water pump 47 is opened. Then, the water pump 47 supplies the nutrients in the feeding tank 48 into the first feeding pipe 41 through the third connecting pipe 45. Subsequently, the electromagnetic valve on the first feeding pipe 41 is opened, and the first feeding pipe 41 supplies materials to the second connecting pipe 44 through the first connecting pipe 43. The second connecting pipe 44 supplies the solution containing aerobic bacteria into the culture pipe 5. When supplying gas to the culture pipe 5, at this time, the electromagnetic valve on the pipeline of the water pump 47 is closed, the electromagnetic valve on the pipeline of the air pump 46 is opened, and the air pump 46 is turned on at the same time.

[0044] A driving motor 49 is fixedly connected to the top of the feeding box 48. The driving motor 49 is controlled by a PLC programming program, which can control the forward and reverse rotation and rotation angle of the driving motor 49. The output end of the driving motor 49 is fixedly connected to a stirring rod 490 that is rotatably connected to the feeding box 48. An electric heating plate 491 is arranged in the feeding box 48. By pouring the bacterial strain powder into the feeding box 48, adding nutrient solution and water into the feeding box 48 at the same time, then driving the stirring rod 490 to rotate by the driving motor 49, and cooperating with the heating of the electric heating plate 491, the aerobic bacterial strains in the feeding box 48 are activated.

[0045] When a large number of aerobic bacteria propagate on the culture ropes 13 of the bacterial strain culture and filtration mechanism in the filtration culture frame 4, at this time, the installation pipe 2 is driven to rotate by the first driving mechanism, so that the filtration culture frame 4 rotates to be perpendicular to the river water flow direction. Then the water flow passes through the filter frame 3 and the filtration culture frame 4 for filtration, preventing floating objects from accumulating in the filtration culture frame 4 and causing damage to the culture and filtration mechanism. Then the filtered sewage enters the filtration culture frame 4. Then the sewage passes through the culture ropes 13, and the aerobic bacteria on the culture ropes 13 carry out biodegradation of the sewage. At the same time, the culture pipe 5 is driven to rotate by the transmission mechanism, the culture pipe 5 drives the first transmission pipe 11 to rotate, and the first transmission pipe 11 drives a plurality of culture ropes 13 to rotate, so that the aerobic bacteria on the culture ropes 13 are in full contact with the sewage for biodegradation and purification. At the same time, a part of the aerobic bacteria are slowly released into the river water under the action of the water flow. At the same time, the feeding mechanism supplies gas to the culture pipe 5. At this time, the solenoid valve on the first transmission pipe 11 is closed, and then the gas is aerated through the first aeration pipe 14. The aeration pipe 14 supplies materials to the aerobic bacteria passing through the position of the culture ropes 13, increasing the oxygen content of the aerobic bacteria and further improving the purification of the sewage. At the same time, after a certain period of time, the transmission mechanism accelerates the rotation of the culture pipe 5, and the culture pipe 5 drives the culture ropes 13 to rotate rapidly, so that the aerobic bacteria on the culture ropes 13 are thrown out under the action of centrifugal force and enter the river water, realizing the intermittent feeding of aerobic bacteria into the river water and further improving the purification effect of the river water. When the feeding is completed, the installation pipe 2 is driven to rotate at this time, so that the culture and filtration mechanisms in the other two filtration culture frames 4 rotate to the filtration position for filtration and purification, and the culture and filtration mechanism in the filtered filter frame 3 rotates to the propagation position for growth and reproduction.

[0046] During the breeding process, the filter culture frame 4 is rotated to a horizontal position opposite to the river water flow, and the culture solution containing the bacterial strain is supplied to the culture tube 5 through the feeding mechanism, and then the culture solution is sprayed out through the liquid outlet 12 on the first transmission tube 11. At the same time, the culture tube 5 is rotated by the transmission mechanism, thereby driving the culture rope 13 to rotate, so that the culture rope 13 can be fully in contact with the solution containing the bacterial strain, so that the culture rope 13 contains a large number of bacterial strains. At the same time, the culture tube 5 is supplied with air through the oxygen supply mechanism, and then aeration and oxygenation are performed through the aeration pipe 14. At the same time, nutrients are provided through the river sewage to realize the breeding and growth of the bacterial strain, so that the bacterial strain can slowly adapt to the sewage, and at the same time, the bred aerobic bacteria are grown and adapted to the sewage environment, which is convenient for the biological purification of the sewage. At the same time, after the subsequent filtration and delivery, the production capacity of the aerobic bacteria is stronger, and the sewage can be better purified after delivery.

[0047] Example 3

[0048] Based on Example 2, please participate Figure 2 and Figure 5 As shown, the cleaning mechanism includes a first gear 61 fixedly connected to the culture tube 5, the outer surface of the first gear 61 is meshed with two second gears 62, the middle of the second gear 62 is fixedly connected with a threaded rod 63 that is rotatably connected to the mounting tube 2 and the filter culture frame 4 respectively, the outer surface of the threaded rod 63 is threadedly fitted with a cleaning block 64, the cleaning block 64 is slidably connected to a guide rod fixedly connected to the mounting tube 2, and cleaning brushes 65 are fixedly connected on both sides of the cleaning block 64.

[0049] After the water-facing surface of the filter frame 3 has filtered for a period of time, the water-facing surface is driven to rotate to the water-receiving surface by rotating the mounting tube 2. The previous water-receiving surface is in a clean state because it has been filtered by the water-facing surface. At this time, the culture tube 5 in the filter frame 3 that filters the river water is driven by the transmission mechanism to rotate back and forth rapidly. At this time, aerobic bacteria are added, and at the same time, the culture tube 5 rotates back and forth rapidly. The culture tube 5 drives the threaded rod 63 to rotate back and forth through the first gear 61 and the second gear 62. The threaded rod 63 drives the cleaning block 64 and the cleaning brush 65 to move back and forth. The cleaning brush 65 cleans the filter frame 3 and the filter culture frame 4 under the rapid reciprocating movement. At the same time, the cleaned impurities are washed out under the action of the water flow, thereby realizing automatic cleaning of the filter frame 3 and the filter culture frame 4.

[0050] Working principle: When in use, insert the mounting posts on the mounting plate 1 into the river channel for fixation. Subsequently, drive the mounting pipe 2 to rotate through the first driving mechanism, so that the two filter frames 3 and the filter culture frame 4 rotate to be perpendicular to the flowing direction of the river surface. Then, the filter frames 3 and the filter culture frame 4 filter and purify the water flowing in the river channel. At the same time, the aerobic bacteria on the bacteria culture and filtration mechanism in the filter culture frame 4 biodegrade the sewage, and slowly release aerobic bacteria into the river channel to improve the water purification effect. At the same time, the other two filter culture frames 4 are perpendicular to the flowing direction of the river, and the impact of the water flow on the filter culture frame 4 is small. At this time, the bacteria culture and filtration mechanism in the filter culture frame 4 uses the nutrients in the water and the automatic oxygen supply of the bacteria culture and filtration mechanism to multiply in large numbers. Due to the small water flow, the aerobic bacteria can multiply in large numbers. When the multiplication reaches a certain level, the first driving mechanism drives the mounting pipe 2 to rotate, so that the filter culture frame 4 after a large number of multiplications rotates to be perpendicular to the flowing direction of the water flow, filters and biodegrades the water flow in the river channel, and slowly releases the aerobic bacteria that have multiplied in large numbers into the water to further purify the sewage in the river channel.

Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
