Description

Technical Field

[0001] The invention relates to a wetland boat suitable for emergency treatment of river and lake shorelines and a balance adjustment method, belonging to the technical field of environmental protection engineering and water treatment. Background Art

[0002] Good hydrodynamic conditions can improve the self-purification capacity of river water bodies. In river and lake bays, due to historical and geographical reasons, water lines have not been connected for a long time, and waterway dead ends will be formed due to insufficient hydrodynamics. Especially when the monsoon season comes, pollutants will be accumulated in the river and lake bays with the wind direction, causing local eutrophication of the water body and even the appearance of a large number of blue algae; along the river and lake banks, when the rainy season comes, sudden heavy rainfall will form surface overflow into the surrounding water bodies because the river and lake shoreline pipelines will not be able to drain in time; and when the river and lake shoreline pipelines are naturally damaged or man-made damaged during use, they are not repaired in time, causing sewage to enter the river; the above situations will all cause eutrophication of river and lake water bodies. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a wetland vessel and a balance adjustment method that can emergency treat sewage entering rivers and lakes and is suitable for emergency treatment of river and lake shoreline pipelines. When sudden pollution occurs in river and lake bays or river and lake areas, the vessel can be driven to a designated location for emergency treatment; when the pollution is eliminated, the vessel can be driven in the river or lake to an empty river or lake water body. The mobile wetland vessel can be transformed with waste hulls to achieve waste recycling.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a wetland ship suitable for emergency treatment of river and lake shorelines, including a hull, a control module located at the first end of the hull, an equipment module located at the second end of the hull, and a processing module located in the middle of the hull, wherein the processing module receives sewage discharged from a pipeline of the river and lake shoreline for treatment, and the processing module includes at least one processing area, and treatment materials for treating sewage are arranged in the processing area.

[0005] More specifically, there are at least two processing areas, and each of the processing areas is connected in series, in parallel, or in a combination of series and parallel.

[0006] More specifically, there are three treatment areas connected in series, which are the first treatment area, the second treatment area and the third treatment area according to the flow direction of the sewage; the third treatment area is located between the first treatment area and the second treatment area.

[0007] More specifically, an activated carbon layer, a water permeable layer, and a lightweight filter layer are sequentially arranged from one end to the other end in the first treatment area. An inlet pipe is arranged at the bottom of the first treatment area, and a first outlet pipe is arranged at the top of the first treatment area. The first outlet pipe is connected to the second treatment area.

[0008] More specifically, a first overflow pipe is arranged at the top of the first treatment area, and the first overflow pipe is connected to the second treatment area.

[0009] More specifically, a number of hollow mesh matrixes are arranged in parallel in the second treatment area. Shellfish and snails for feeding on algae are arranged on the mesh matrixes. A second inlet pipe is arranged at one end of the second treatment area, and a second outlet pipe is arranged at the other end of the second treatment area. The second inlet pipe is connected to the effluent of the first treatment area, and the second outlet pipe is connected to the third treatment area.

[0010] More specifically, a second overflow pipe is arranged at the top of the second treatment area, and the second overflow pipe is connected to the third treatment area.

[0011] More specifically, the third treatment area is a clear water tank. A third inlet pipe and a third outlet pipe are arranged in the third treatment area. The third inlet pipe receives the influent and effluent from the second treatment area.

[0012] More specifically, a first distance measuring component is arranged at the first end of the hull, and a second distance measuring component is arranged at the second end of the hull. The distances from the first distance measuring component and the second distance measuring component to the water surface are measured to judge the balance of the hull.

[0013] A method for balancing adjustment of a wetland boat

[0014] S1. The first distance measuring component measures the distance from the first end of the hull to the water surface as the first height, and the second distance measuring component measures the distance from the second end of the hull to the water surface as the second height, and transmits the first height and the second height to the control module for processing;

[0015] S2. The control module compares the first height and the second height, and judges whether the difference between the two is less than the set threshold value in the control module. If it is, no action is taken. If not, go to step S3;

[0016] S3. Judge whether the first height of the hull is less than the second height. If so, increase the water inflow of the treatment materials in the first treatment area or reduce the water inflow to the second treatment area. If not, reduce the water inflow of the treatment materials in the first treatment area or increase the water inflow to the second treatment area.

[0017] The beneficial effects of the present invention are as follows: Through the above structure, the autonomous movement of the hull can be realized, and it can be conveniently moved to the banks of rivers and lakes as needed to receive sewage from the shore for treatment, and emergency treatment can be carried out on the polluted water bodies in areas such as river and lake bays, dead-end canals, and along the river channels. After the pipeline repair work is completed, the hull can be driven in the river or lake to an open water area. The mobile wetland ship can be transformed from a waste hull, realizing the reuse of waste. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] A wetland boat applicable to the emergency treatment of river and lake shorelines includes a hull 1, a control module 2 located at the first end (stern) of the hull 1, an equipment module 3 located at the second end (bow) of the hull 1, and a treatment module located in the middle of the hull 1. The positions of the control module 2 and the equipment module 3 can be swapped according to needs. The treatment module receives the sewage discharged from the river and lake shoreline pipelines for treatment. The treatment module includes at least one treatment area, and treatment materials for treating sewage are arranged in the treatment area. The hull can freely navigate on the river and lake through the control module 2. The equipment module 3 at the bow includes a power supply device, an engine device, etc. The control module 2 at the stern is mainly used to control the treatment of sewage in the treatment module. At the same time, the direction control position of the hull is reserved and can be located at the first end (stern) of the hull 1 or the second end (bow) of the hull 1.

[0030] The power supply device can be realized by one or a combination of generator power supply, emergency power supply, DC battery power supply, and solar power supply, or can be powered by other clean energy sources, and is used to provide power for all lighting, communication, and other electrical equipment on the hull 1.

[0031] When there is one treatment area, treatment materials are arranged in the treatment area, an inlet pipe and an outlet pipe are arranged, and at the same time, it is controlled through the control module 2 to ensure the timely treatment of the water coming from the shore.

[0032] When there are two or more treatment areas, the treatment areas can be connected in series, parallel or in combination. At the same time, the treatment materials in each treatment area can be the same or different. Each treatment area is provided with an inlet pipe and an outlet pipe, and series and parallel connections are achieved through the cooperation between the inlet pipes and the outlet pipes of each treatment area. At the same time, each treatment unit can be provided with an overflow pipe. When the incoming water is excessive, it can overflow to the next-level treatment unit through the overflow pipe for treatment.

[0033] As Figure 1 With Figure 2 shown, based on the size of the hull 1 and the different types of sewage on the banks of rivers and lakes in various places, the number of treatment areas and the treatment materials in the treatment areas can be set as needed. In this solution, three treatment areas are adopted, and the following will describe in detail with three treatment areas.

[0034] There are three treatment areas in series, namely the first treatment area 4, the second treatment area 5 and the third treatment area 6, and they are arranged according to the flow direction of the sewage. That is, the sewage first enters the first treatment area 4, then enters the second treatment area 5, and finally enters the third treatment area 6 and is discharged from the third treatment area 6. Three areas are divided and separated in the middle of the hull 1. The third treatment area 6 is located between the first treatment area 4 and the second treatment area 5. The first treatment area 4 is close to the bow, and the second treatment area 5 is close to the stern. When the sewage enters the second treatment area 5 from the first treatment area 4, it needs to cross the third treatment area 6.

[0035] The division between the control module 2, the equipment module 3, the first treatment area 4, the second treatment area 5 and the third treatment area 6 is usually the original division of the hull 1. To maintain the balance of the hull 1, it can be symmetrically divided according to the size of the hull 1, with the center line of the hull 1 as the axis of symmetry. For example, if the hull 1 itself is 20 meters, the original bow space is 2 meters, and the original stern space is 3 meters, then the spaces at the bow and the stern are both divided into 3 meters based on the larger space to ensure the balance of the bow and the stern. The middle treatment area is evenly distributed or distributed according to the weights of different areas, mainly to ensure the balance of the bow and the stern.

[0036] As Figure 4 With Figure 5The treatment materials in the first treatment area 4 are arranged in sequence from one end to the other end, including an activated carbon layer 41, a permeable layer 42 and a light filter material layer 43, which are conducive to the removal of nitrogen, phosphorus and organic matter. A variety of different biological fillers can also be combined according to different water quality conditions, and the thickness can also be increased or decreased according to the degree of pollution, so as to achieve the effect of improving the removal of different pollutants. A first water inlet pipe 44 is arranged at the bottom of the first treatment area 4, and a first water pump, a first flow meter and a first solenoid valve are arranged on the first water inlet pipe 44. The flow rate of the water entering the first treatment area 4 is adjusted by the control module 2; a first water outlet pipe 45 is arranged at the top of the first treatment area 4, and the first water outlet pipe 45 is connected to the second treatment area 5 to send the water treated by the first treatment area 4 to the second treatment area 5.

[0037] At the same time, a first overflow pipe 46 is installed at the top of the first treatment area 4. The first overflow pipe 46 is connected to the second treatment area 5. When the first treatment area 4 receives too much water, the sewage can be directly discharged into the second treatment area 5 through the first overflow pipe 46. The first overflow pipe 46 is installed at a height higher than the first outlet pipe 45.

[0038] like Figure 4 and Figure 6 The treatment material in the second treatment area 5 shown includes a plurality of hollow mesh matrices 51 arranged in parallel and biological filter materials suspended on the mesh matrices 51 to effectively remove nitrogen elements; when algae appear in the incoming water, shellfish that feed on algae, such as green-lipped mussels, river clams, pleated crown clams, triangular fan clams, etc., can also be suspended to remove excess algae in the water body. Each mesh matrix 51 can be completely stuck in the longitudinal section or cross section of the hull 1, so that the water flow must pass through each mesh matrix 51 one by one; a second water inlet pipe 52 is arranged at one end of the second treatment area 5, and a second water outlet pipe 53 is arranged at the other end of the second treatment area 5, and the second water inlet pipe 52 is connected to the first water outlet pipe 45 The second water inlet pipe 52 is used to receive the outlet water of the first treatment area 4. The second water pump, the second flow meter and the second solenoid valve are arranged on the second water inlet pipe 52. The flow rate of the water inlet to the second treatment area 5 is adjusted by the control module 2. At the same time, a check valve is installed on the second water inlet pipe 52 to prevent the sewage from flowing back into the first treatment area 4. A second water outlet pipe 53 is arranged on the top of the second treatment area 5. The second water outlet pipe 53 is connected to the third treatment area 6 to send the water treated in the second treatment area 5 to the third treatment area 6. The second water inlet pipe 52 and the second water outlet pipe 53 are respectively arranged at the two corners of the second treatment area 4 and are diagonally distributed to facilitate the water flow to flow through a longer path in the second treatment area 5.

[0039] At the same time, a second overflow pipe 54 is installed on the top of the second treatment area 5, and the second overflow pipe 54 is connected to the third treatment area 6. When there is a lot of water in the second treatment area 5, the sewage can be directly discharged into the third treatment area 6 through the second overflow pipe 54. The second overflow pipe 54 is installed at a height higher than the second outlet pipe 53.

[0040] As shown in Figure 4 Figure 3, the third treatment area 6 is a clear water tank. A third water inlet pipe 61 and a third water outlet pipe 62 are arranged in the third treatment area 6. The third water inlet pipe 61 is connected to the second water outlet pipe 52 to receive the water from the second treatment area 5, and the third water outlet pipe 62 directly discharges the water in the third treatment area 6 into the river or lake; A third overflow pipe can also be arranged in the third treatment area 6. The height of the third overflow pipe is higher than that of the third water outlet pipe 62. When the incoming water in the third treatment area 6 is too much, it can be directly discharged into the river or lake through the third overflow pipe.

[0041] No openings are made in the entire hull 1. All water inlets and outlets are powered by water pumps to maintain the integrity of the hull 1.

[0042] As shown in Figure 3 Figure 5, there is a water line 9 on the surface of the hull 1. The water line 9 is located at two-thirds of the entire ship height. The internal heights of the first treatment area 4, the second treatment area 5, and the third treatment area 6 are lower than or flush with the water line 9.

[0043] Based on the above structure, when the hull 1 is treating sewage, the two ends of the hull 1 may have different weights and tilt. Therefore, in order to keep the hull 1 balanced, a first distance measuring component 7 is arranged at the first end (stern) of the hull 1, and a second distance measuring component 8 is arranged at the second end (bow) of the hull 1. The installation positions of the first distance measuring component 7 and the second distance measuring component 8 are on the same horizontal plane. The distances measured by the first distance measuring component 7 and the second distance measuring component 8 from the water surface are used to judge the balance of the hull 1. Both the first distance measuring component 7 and the second distance measuring component 8 use water surface distance measuring devices. During the initial design, the balance can be achieved by increasing or decreasing the treatment materials in the first treatment area 4 and the second treatment area 5, and during the treatment process, the balance can be achieved by increasing the sewage volume in the first treatment area 4 and the second treatment area 5.

[0044] As shown in Figure 7 Figure 6, the method for adjusting the hull balance is as follows:

[0045] S1. The overall height of the measured hull is H. The first distance measuring component 7 measures the distance from the stern of the hull 1 to the water surface as the first height H1, and the second distance measuring component 8 measures the distance from the bow of the hull 1 to the water surface as the second height H2, and transmits the first height H1 and the second height H2 to the control module 2 for processing.

[0046] S2. The control module 2 compares the first height H1 and the second height H2, and judges whether the difference between the two is less than the set threshold 5%H in the control module 2. If so (|H1 - H2| < 5%H), no action is taken. If not (|H1 - H2| > 5%H), go to step S3.

[0047] S3. Determine whether the first height H1 of the hull 1 is less than the second height H2 (H1<H2). If so, increase the water flow to the first treatment area 4 or reduce the water flow to the second treatment area 5. Otherwise, reduce the water flow to the first treatment area 4 or increase the water flow to the second treatment area 5.

[0048] When treating sewage on the banks of rivers and lakes, it is necessary to select a wetland boat according to the width and depth of the river and lake water body. The width of the hull 1 needs to be less than one-third of the width of the water body to ensure that when the wetland boat has problems or meets other boats in the same water body, both parties can navigate safely; the height of the wetland boat hull needs to be less than one-half of the measured water body to ensure that the wetland boat can completely float on the water surface. This height can prevent the wetland boat from encountering sudden drought weather or other emergencies during the use of the wetland boat, and the river and lake water bodies need to be quickly pumped out, causing the water level of the water body to drop rapidly.

[0049] In summary, by arranging the first treatment area 4, the second treatment area 5 and the third treatment area 6 on the hull 1 to treat the sewage in the river and lake shoreline pipelines, it can be used in emergencies when the sewage pipeline is damaged and needs to be repaired, upgraded, or encounters sudden heavy rainfall or excessive water. It can be used in multiple river and lake shorelines and is easy to move. It can directly intercept, store and treat the water in the damaged pipes on the river and lake banks. When the pipeline repair work is completed, the hull 1 can be driven in the river or lake to an empty river or lake water body. The mobile wetland ship can be transformed with waste hulls to achieve waste recycling.

[0050] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
