Description

Technical Field

[0001] The present invention belongs to the technical field of water environment treatment, and particularly relates to an efficient water surface floating power device using air-lift and a water environment governance system. Background Art

[0002] The 2023 Ecological Environment Bulletin of the Ministry of Ecology and Environment shows that among the 205 important lakes (reservoirs) where trophic status monitoring was carried out, eutrophic lakes (reservoirs) accounted for 27.3%. China has more than 24,800 lakes and more than 98,000 reservoirs. Considering the eutrophication ratio of the Ministry of Ecology and Environment in 2023, more than 33,000 lakes (reservoirs) across the country are in a eutrophic state. Considering that the Ministry of Ecology and Environment only monitored important water bodies, the actual situation will be more severe. In 2023, the Ministry of Ecology and Environment clearly put forward new goals for river and lake ecological governance and protection, not only to effectively eliminate water body eutrophication, improve water quality, but also to increase biodiversity and stabilize the ecosystem. Therefore, the whole country is increasing investment in the treatment of lakes (reservoirs) to improve the water ecological environment of lakes (reservoirs).

[0003] Nitrogen and phosphorus are the most fundamental causes of eutrophication. Therefore, a large number of water body denitrification and dephosphorization equipment and materials have emerged on the market. However, when these equipment or materials are applied to lakes (reservoirs), they are all placed or put in fixed areas, which are prone to form effective treatment in local areas or be covered by silt at the bottom and cannot be effectively treated. When the materials or equipment need to cover the entire water area or achieve a floating state in the water body, the method of uniform layout or movable device is adopted. However, the method of uniform layout will lead to too many related equipment placed inside the water body. Using a movable device can effectively treat the water body and there are fewer equipment placed in the water body. However, existing water body movable devices all use propellers and rudders, and their energy consumption is relatively large. Summary of the Invention

[0048] The following will describe in detail the preferred embodiments of the present invention with reference to the accompanying drawings, so as to more clearly understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present invention, but only to illustrate the essential spirit of the technical solution of the present invention.

[0049] In the following description, for the purpose of illustrating various disclosed embodiments, certain specific details are set forth to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of these specific details. In other instances, well-known devices, structures and techniques associated with the present application may not be shown or described in detail so as not to unnecessarily obscure the description of the embodiments.

[0050] References to "one embodiment" or "an embodiment" throughout the specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of "in one embodiment" or "in an embodiment" throughout the specification are not necessarily all referring to the same embodiment. Additionally, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0051] In the following description, in order to clearly show the structure and working mode of the present invention, many directional terms will be used for description. However, words such as "front", "rear", "left", "right", "outside", "inside", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as limiting terms.

[0052] Referring to Figures 1 to 5 , an embodiment of the present invention provides a highly efficient water surface floating power device using air-lift, which includes a housing 1, an air-lift water buffer zone 2, a plurality of air-lift water outlet zones 3, a plurality of outlet weirs 4, a plurality of outlet pipes 5 and an air-lift device.

[0053] The housing 1 is a floating housing 1 on water. Of course, after several devices are installed on the housing 1, the housing 1 should still be able to float on water. An air-lifted water buffer zone 2 and several air-lifted water discharge zones 3 are arranged on the housing 1. The air-lifted water buffer zone 2 and the several air-lifted water discharge zones 3 are adjacent to each other respectively. Each air-lifted water discharge zone 3 is separated from the air-lifted water buffer zone 2 by a weir 4 with different heights. The several air-lifted water discharge zones 3 can be adjacent to each other in sequence and separated from each other, or can be arranged around the air-lifted water buffer zone 2 at a certain distance. Each air-lifted water discharge zone 3 is a relatively independent area.

[0054] The number of the water outlet pipes 5 is the same as the number of the air-lifted water discharge zones 3. One water outlet pipe 5 corresponds to one air-lifted water discharge zone 3. One end of each water outlet pipe 5 is communicated with a corresponding air-lifted water discharge zone 3, and the other end of each water outlet pipe 5 is arranged below the water level. This water level is the water level after the housing 1 floats on water, that is to say, the water outlet pipe 5 should extend into the water.

[0055] An air-lifting device is arranged on the housing 1, and the air-lifting device is used to lift water to the air-lifted water buffer zone 2.

[0056] When the present invention works, the water on which the housing 1 floats is lifted to the air-lifted water buffer zone 2 by the air-lifting device. During the continuous lifting process of the water, the water in the air-lifted water buffer zone 2 overflows to the weir and is discharged to the air-lifted water discharge zone 3 through the weir, and then is discharged from the water outlet pipe 5 corresponding to the air-lifted water discharge zone 3, and finally the movement of the device is realized.

[0057] When the air-lifting air volume of the air-lifting device is small and thus the water supply volume is small, all the air-lifted water is discharged from the weir with the lowest weir elevation. As the air-lifting air volume gradually increases and thus the water supply volume gradually increases, the air-lifted water discharge volume becomes larger, and the water volume that cannot be discharged in time through the water outlet pipe 5 corresponding to the lowest weir will be discharged from other weirs from low to high in sequence. When the water is discharged only from one water outlet pipe 5, the device of the present invention only moves in one direction. When the water is discharged from several water outlet pipes 5, the device can realize turning movement, which can basically meet the movement requirements on the water surface.

[0058] Existing water body moving devices (carrying slow-release materials or other reaction equipment) all use propellers and rudders, which consume a large amount of energy. Propellers and rudders achieve rapid start-up and movement by using high power. However, in the process of water environment treatment, the equipment and materials placed in the water body are objects that need to react for a long time. Therefore, in actual application, there is no immediate and rapid actual demand for moving devices. The present invention aims at the movement on or under the water surface. By discharging water flow backward and moving forward by its reaction force, and in view of the scene requirement of relatively small hydrodynamic force required for the water surface floating device used in water environment treatment, an air-lift device is used in cooperation with the interaction of the air-lift water buffer zone 2, the air-lift water outlet zone 3 and the water outlet pipe 5. The air-lift is used to discharge the air-lifted water in a specified direction to realize the moving water surface floating power device. The power required for the air-lift process using atmospheric pressure is much smaller than that of a propeller.

[0059] In one embodiment, referring to Figure 1 and Figure 3 , among several weirs 4, the height of the weir 4 on one side is the lowest and serves as the first weir 41, and the height of the weir 4 on the other side is higher than that of the first weir 41 and serves as the second weir 42.

[0060] When there are at least three weirs 4, the remaining weirs 4 are located between the first weir 41 and the second weir 42, and the heights of the remaining weirs 4 are all higher than that of the second weir 42 and gradually increase in the direction from the second weir 42 to the first weir 41.

[0061] As Figure 3 shown, the device has four weirs 4, and the heights from low to high are the first weir 41, the second weir 42, the third weir 43 and the fourth weir 44 respectively. The first weir 41 is arranged on one side, the second weir 42, the third weir 43 and the fourth weir 44 are arranged in sequence, and the fourth weir 44 is located on the side of the first weir 41, and the second weir 42 is far from the first weir 41. That is, from one side to the other side are the first weir 41, the fourth weir 44, the third weir 43 and the second weir 42 respectively.

[0062] When the device has four weirs 4, the corresponding air-lift water outlet zone 3 and water outlet pipes 5 are also four. The four water outlet pipes 5 are the first water outlet pipe 51, the second water outlet pipe 52, the third water outlet pipe 53 and the fourth water outlet pipe 54 respectively, and are respectively used to receive the water overflowing from the first weir 41, the second weir 42, the third weir 43 and the fourth weir 44.

[0063] When the air-lifting air volume of the air-lifting device is small and thus the water supply volume is small, all the air-lifted water is discharged from the first water outlet weir 41, and then the water is discharged from the first water outlet pipe 51, achieving the purpose of the device moving forward in one direction. When the device needs to turn, the air-lifting air volume is increased, and thus the water supply volume gradually increases. The water is gradually discharged from the second water outlet weir 42, the third water outlet weir 43, and the fourth water outlet weir 44, and then the water is discharged from the second water outlet pipe 52, the third water outlet pipe 53, and the fourth water outlet pipe 54. As Figure 5 shown, the device gradually turns counterclockwise and moves along a curve.

[0064] In one embodiment, the top water outlet end face shape of the water outlet weir 4 is linear, curved, or arc-shaped.

[0065] Among them, the curved shape is a shape with at least one bend different from the arc shape, such as a lying s-shaped.

[0066] Referring to Figure 4 (a), the top water outlet end face shape of the water outlet weir 4 is linear.

[0067] Referring to Figure 4 (a), the top water outlet end face shape of the water outlet weir 4 is arc-shaped.

[0068] In one embodiment, a locator and a control module are installed in the housing 1. The locator provides the position information of the housing 1 to the control module. The control module is used for: generating an operation trajectory according to the current position information and the historical position information, judging the future movement direction of the device according to the operation trajectory, and adjusting the future movement direction of the housing by controlling the water supply volume sent to the air-lifted water buffer area of the air-lifting device, so as to move the housing to a preset target position.

[0069] The locator usually regularly provides the position information to the control module so that the controller can obtain the current position information and the historical position information for generating the operation trajectory.

[0070] Of course, when the air-lifting device is not operating, the housing 1 can drift freely under the drive of the water flow. Therefore, the control module can be controlled regularly, such as once a day, three days, or one week.

[0071] Since the larger the air-lifting air volume, the more the water supply volume, and thus the water can not only be discharged from the first water outlet pipe 51, but also from the second water outlet pipe 52, and even the third water outlet pipe 53 and the fourth water outlet pipe 54, achieving the purpose of the device gradually turning counterclockwise and moving along a curve. Therefore, in this embodiment, by controlling the water supply volume of the air-lifting device, the purpose of controlling the device to turn and thus adjusting the movement direction can be achieved.

[0072] For example, the current position information and the previous position area are used as the future movement direction, and the direction between the current position information and the preset position information is used as the target direction. By determining whether the future movement direction is consistent with the target direction or within the preset angle range of the target direction, it is determined whether the future movement direction needs to be adjusted. If the future movement direction is consistent with the target direction or within the preset angle range of the target direction, no direction adjustment is required, and water is discharged from the first water outlet pipe 51, and the device can move forward in one direction. Otherwise, it is considered that the device needs to adjust its direction, and the water supply amount sent to the air-lift water buffer area by controlling the air-lift device is used to adjust the housing to gradually turn counterclockwise to the future movement area.

[0073] In this embodiment, since the application field of this device determines that the movement direction of this device does not need to be very precise, and its movement trajectory only needs to roughly cover the position area within a certain range where the target position information is located. Therefore, when controlling this device, the future movement direction does not need to be very precise either, and only the target area within a certain range of the target direction can be used as the future movement area.

[0074] The relationship between the duration of controlling the water supply amount of the gas device, the counterclockwise turning amplitude of the housing 1, and the adjustment angle of the direction can be determined in advance through experiments, so as to determine the duration of controlling the water supply amount of the gas device according to the angle between the future movement direction and the target direction, and finally realize the adjustment of the direction.

[0075] In one embodiment, a water-blocking area surrounded by the water-blocking plates 61 is provided on the housing 1. The water-blocking area is divided into an air-lift water buffer area 2 and an air-lift water total outlet area by a plurality of adjacent water outlet weirs 4. The air-lift water total outlet area is divided into a plurality of air-lift water outlet areas 3 by a plurality of partition plates 62 with each water outlet weir 4 as the boundary.

[0076] As Figure 1 shown, the air-lift water buffer area 2 is surrounded by part of the water-blocking plates 61 and a plurality of adjacent water outlet weirs 4. A single air-lift water outlet area 3 is surrounded by the other part of the water-blocking plates 61, the partition plates 62, and a single water outlet weir 4.

[0077] In one embodiment, the heights of the water-blocking plates 61 and the partition plates 62 are both higher than the highest water level of the water sent to the water-blocking area by the air-lift device, so as to ensure that water can only flow from each water outlet weir 4 to each water outlet pipe 5.

[0078] In one embodiment, referring to Figure 1 , the water-blocking area is a fan-shaped area, the air-lift water buffer area 2 is also a fan-shaped area, and a plurality of air-lift water outlet areas 3 are arranged in a fan shape.

[0079] In one embodiment, a plurality of water outlet pipes 5 are arranged in a fan shape on one side of the housing 1.

[0080] Referring toFigure 1 , the four water outlet pipes 5 are evenly arranged circumferentially on about 1 / 4 of the shell side.

[0081] In one embodiment, the outer peripheral contour of the shell 1 is circular, curved or curvilinear to reduce the resistance when the device turns.

[0082] Refer to Figure 1 , the shell 1 is cylindrical as a whole, so its outer peripheral contour is circular. The shell 1 moves through the four water outlet pipes 5 arranged on about 1 / 4 of the shell side.

[0083] The internal structure and material of the shell 1 can be set according to specific implementation situations.

[0084] In one embodiment, the outer peripheral contour of the remaining part of the shell 1 except where the water outlet pipes 5 are arranged is circular, curved or curvilinear.

[0085] Refer to Figure 1 , the outer peripheral contour of the remaining about 3 / 4 part of the shell 1 except the four water outlet pipes 5 arranged on about 1 / 4 of the shell side is circular, curved or curvilinear. That is to say, the outer peripheral contour of the about 1 / 4 shell where the four water outlet pipes 5 are arranged may not be circular, curved or curvilinear.

[0086] In one embodiment, the efficient water surface floating power device using air-lift further includes a power supply device. The power output end of the power supply device is connected to the electrical devices including the air-lift device on the shell 1.

[0087] In one embodiment, the power supply device includes a wind power generation windmill and a storage battery. The power supply end of the wind power generation windmill is connected to the storage battery, and the power output end of the storage battery is connected to the electrical devices including the air-lift device on the shell 1.

[0088] In this embodiment, through the wind power generation windmill and the storage battery, not only can the device store electricity to achieve the purpose of energy saving, but also the wind power generation windmill can be used to assist the device to move.

[0089] At this time, the power supply device may not be equipped with other power supplies, and only the wind power generation windmill and the storage battery are used. When there is no wind in the environment and the storage battery has no electric energy, the device floats due to the wind power generation windmill and the horizontal water flow. When there is wind in the environment and the storage battery has electricity, the movement or the adjustment of the movement direction can be carried out by controlling the water supply volume of the air-lift device.

[0090] In one embodiment, the air supply device in the air-lift device uses a blower or an air pump.

[0091] In one embodiment, the air pressure of the blower is 200 Pa - 500 Pa to ensure that the air supply pipe 72 conveys air to a deep enough position.

[0092] In one embodiment, the air-lift device can directly adopt the air-lift device in the prior art that can realize water supply through the air-lift principle.

[0093] Referring to Figure 1 and Figure 2 , the air-lift device preferably includes an air supply device 71, an air supply pipe 72 and an air-lift riser 73.

[0094] The air supply device 71 is arranged on the housing 1. The air outlet of the air supply device 71 is connected to one end of the air supply pipe 72, and the other end of the air supply pipe 72 communicates with the air-lift riser 73 located below the horizontal plane.

[0095] The air-lift riser 73 is arranged on the housing 1 and both ends extend out of the housing 1. An air-lift water inlet is arranged at the lower part of the air-lift riser 73. The height of the air-lift water inlet is not higher than the height of the horizontal plane. An air-lift water outlet is arranged at the upper part of the air-lift riser 73, and the air-lift water outlet communicates with the air-lift water buffer area 2.

[0096] When the housing 1 is placed on the water, water can enter the air-lift riser 73 from the air-lift water inlet. At this time, the other end of the air supply pipe 72 should communicate with the air-lift riser 73 under the water.

[0097] For example, an air supply device 71 such as a blower or an air pump transports air to the air-lift riser 73 through the air supply pipe 72, lifts the water in the air-lift riser 73, and the lifted water overflows from the air-lift water outlet to the water-lifting buffer area 2.

[0098] In one embodiment, a part of the upper part of the air-lift riser 73 extends into the air-lift water buffer area 2, and an opening 731 is cut out on the top pipe section of the air-lift riser 73 facing the air-lift water buffer area 2 as the air-lift water outlet.

[0099] In one embodiment, the top pipe section of the air-lift riser 73 is connected to a tee pipe section, and one of the pipe orifices of the tee pipe section extends into and communicates with the air-lift water buffer area 2.

[0100] The embodiment of the present invention also provides a water environment treatment system, which includes the high-efficiency water body surface floating power device using air-lift provided in the above embodiments of the present invention.

[0101] In one embodiment, the high-efficiency water body surface floating power device using air-lift of the present invention is not limited to floating on the water, but can also float on other liquids, so that the present invention can be applied to other scenarios of floating on liquids.

[0102] In one embodiment, the water environment treatment system further includes:

[0103] A slow-release agent or water environment treatment equipment is arranged inside or at the bottom of the high-efficiency water body surface floating power device using air-lift.

[0104] In one embodiment, the sustained-release medicament is a sustained-release nitrogen-removing material package.

[0105] In one embodiment, the device for water environment treatment is a device for collecting floating algae.

[0106] In one embodiment, referring to Figure 6 , the housing 1 of the high-efficiency water surface floating power device using air lift adopts a cylindrical structure. The other structures of the high-efficiency water surface floating power device using air lift in this embodiment adopt the high-efficiency water surface floating power device using air lift provided in the above embodiments of the present invention, and the other structures are omitted in Figure 6 herein.

[0107] Four bags of sustained-release nitrogen-removing material packages 8 for release in the water body are respectively suspended at the bottom of the housing 1. Each bag of the sustained-release nitrogen-removing material package contains 1 kg of sustained-release denitrification material. The sustained-release nitrogen-removing material package can be directly set at the bottom of the housing 1 by using existing materials.

[0108] The material and size of the housing 1 of the high-efficiency water surface floating power device using air lift are designed accordingly according to the weight of the sustained-release nitrogen-removing material package, and it should be ensured that the housing 1 can float on the water.
