Description

Technical Field

[0001] This invention relates to the field of water body environmental protection and treatment technology, specifically to an automatic sewage discharge system for enclosures and a dynamic sewage discharge method. Background Technology

[0002] In fields such as water conservancy projects, construction, aquaculture, and urban landscape water body maintenance, it is often necessary to set up temporary or permanent enclosure structures to create independent work areas or water bodies. These areas easily accumulate floating pollutants (such as fallen leaves, plastic, oil, and algae) carried by wind and water flow, affecting water quality and the working environment. Currently, cleaning up water surface pollution within enclosures mainly relies on manual dredging or fixed filtration equipment.

[0003] Manual dredging is inefficient, costly, and poses safety risks, and cannot achieve real-time cleaning. Existing fixed filtration equipment, such as fixed trash racks or water pump systems, typically lacks intelligent judgment and dynamic response capabilities. For example, patent CN216341424U discloses a dustproof enclosure structure for construction projects, including a baffle with a filter screen fixedly installed on its surface, which intercepts trash through floats and the trash net.

[0004] However, the existing enclosure structure has a fixed sewage outlet direction, making it impossible to optimize the sewage discharge path according to wind direction, resulting in a limited cleaning range and low energy efficiency. When the wind direction changes, pollutants may accumulate on the upwind side of the enclosure, causing them to spread disorderly within the enclosure and resulting in low removal efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an automatic sewage discharge system and dynamic sewage discharge method for enclosures, which solves the technical problems in the prior art where the sewage discharge structure of enclosures cannot dynamically adjust the sewage discharge direction according to the wind direction, the pollutant removal efficiency is low, and the energy utilization rate is not high.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides an automatic sewage discharge system for enclosures, comprising at least three enclosure components, a sewage discharge drive, a water surface pollution monitoring device, a wind direction and wind force measuring device, and a control unit; each enclosure component includes an enclosure body, an isolation component, and a filter component, the at least three enclosure bodies are connected end to end in sequence to jointly enclose a closed area for containing water, a sewage discharge port communicating with the closed area is provided on the side wall of the enclosure body, the isolation component and the filter component are movably installed on the enclosure body and are set corresponding to the sewage discharge port; the sewage discharge drive includes a first drive and a second drive, the first drive is tractively connected to the isolation component and is used to drive the isolation component to open and close the sewage discharge port; the second drive is tractively connected to the filter component and is used to drive the filter component to switch between a filtering position covering the sewage discharge port and a receiving position away from the sewage discharge port; the water surface pollution monitoring device is located in the closed area and is used to monitor water surface pollutants; the wind direction and wind force measuring device is located in the enclosure component and is used to monitor wind direction and wind force.

[0007] In some embodiments, the automatic sewage discharge system for the enclosure also includes at least three sets of wind compensation devices, each set of wind compensation devices corresponding to a main body of the enclosure, for generating a compensating airflow in the same direction as the ambient wind.

[0008] In some embodiments, the wind compensation device includes a rotary drive mechanism and at least one fan unit. The fan unit is rotatably mounted on the enclosure body or filter via the rotary drive mechanism. The rotary drive mechanism can drive the fan unit to rotate around a vertical axis to adjust its air delivery direction to be consistent with the ambient wind direction.

[0009] In some embodiments, the automatic sewage discharge system for enclosures further includes at least three fixing members, which are respectively disposed at the connection between two adjacent enclosure bodies. The lower end of the fixing member is provided with an anchoring part for insertion into the bottom of the water, and the side of the enclosure body is slidably connected to the fixing member.

[0010] In some embodiments, the enclosure body includes a flexible curtain, a counterweight, and a rigid enclosure member; the two sides of the flexible curtain are slidably connected to the fixing member; the counterweight is continuously or intermittently arranged along the bottom edge of the flexible curtain; the rigid enclosure member is fixed to the top of the flexible curtain and sealed to the flexible curtain, and the two sides of the rigid enclosure member are slidably connected to the fixing member; the drain outlet is opened at the top of the rigid enclosure member, and the inner side of the rigid enclosure member is provided with a guide groove extending vertically, the filter member is slidably engaged with the guide groove, and can move between the filter position of the closed drain outlet and the storage position of the bottom of the guide groove under the drive of the second driving member.

[0011] In some embodiments, the automatic sewage discharge system for enclosures further includes at least three sets of buoyancy components, which are respectively disposed on the outside of each enclosure body or isolation component and distributed along the extension direction of the enclosure body or isolation component, and the height position of the buoyancy components corresponds to the central axis position of the isolation component.

[0012] In some embodiments, the main body of the enclosure is provided in three sets, and two adjacent enclosure main bodies are connected by fasteners to jointly enclose an equilateral triangle closed area; The automatic sewage discharge system for the enclosure also includes a control unit, which is electrically connected to the first drive component, the second drive component, the water surface pollution monitoring equipment, and the wind direction and force measuring device. The control unit receives pollutant information and environmental wind direction and force data, and decides whether to initiate sewage discharge based on a preset sewage discharge threshold. The control unit is configured to: receive and process monitoring data from the water surface pollution monitoring equipment and the wind direction and force measuring device; when it is determined that the water surface pollutants have reached the preset sewage discharge standard, determine the target enclosure body located downwind based on the real-time wind direction; control the first and second drive components corresponding to the target enclosure body to operate synchronously to open the isolation components and drive the filter components to the storage position; simultaneously, control the first drive components corresponding to other non-target enclosure bodies to open their isolation components; thereby utilizing natural wind force to drive water surface pollutants towards the target enclosure body and discharge them into the closed area through its discharge outlet and filter components.

[0013] In some embodiments, the automatic sewage discharge system for enclosures also includes an oxygen monitoring device, which is located within the enclosed area and signal-connected to the control unit for monitoring the dissolved oxygen content in the water. When the dissolved oxygen content is lower than the preset dissolved oxygen threshold, the control unit controls all the first drive components to activate all the isolation components to exchange water.

[0014] Secondly, the present invention also provides a dynamic sewage discharge method, using an automatic sewage discharge system for enclosures as described in any of the above claims, the method comprising: An automatic sewage discharge system is deployed in the target water area. Water surface pollution monitoring equipment is used to continuously monitor water surface pollutants in the closed area, and environmental wind direction and wind force data are collected in real time through wind direction and wind force measurement devices. The control unit receives monitoring data and, when it determines that the pollutants on the water surface have reached the preset discharge standard, initiates the automatic discharge procedure. The control unit determines the target sewage discharge edge located downwind based on the real-time wind direction; The isolation components and filter components corresponding to the target sewage discharge edge are opened synchronously to form a filtration and sewage discharge channel; at the same time, the isolation components on other non-target fence edges are opened. Under the influence of natural wind, pollutants on the water surface accumulate towards the target discharge edge and are discharged into the closed area through the filtration and discharge channel.

[0015] In some embodiments, the automatic sewage discharge system for enclosures is also equipped with a wind compensation device; During the initiation of the automatic sewage discharge program, the control unit simultaneously acquires real-time wind force data; If the real-time wind force is less than the preset wind force value, the wind compensation device on at least one of the main bodies of the enclosure located upwind will be activated and controlled to generate a compensating airflow in the same direction as the natural wind to assist in driving the pollutants. If the real-time wind force is greater than or equal to the preset wind force value, the sewage discharge will be completed solely by natural wind force.

[0016] Compared with existing technologies, the automatic sewage discharge system and dynamic sewage discharge method provided by this invention, through the integration of a dynamically adjustable sewage outlet structure, multi-parameter environmental monitoring equipment, and an intelligent control unit, achieves real-time monitoring and targeted removal of pollutants on the water surface within the enclosure. The system utilizes at least three interconnected enclosure components to form a closed water area. Each component is equipped with independently controllable isolation and filtering elements. Combined with wind direction and force data, the system dynamically adjusts the opening and closing status of the sewage outlet and the position of the filtering elements via a sewage discharge drive mechanism, ensuring that pollutants gather towards the target sewage discharge edge and are efficiently discharged under the influence of natural wind or auxiliary wind compensation devices. Compared to traditional fixed sewage discharge structures, this invention can adaptively optimize the sewage discharge strategy based on pollutant distribution and meteorological conditions, improving pollutant removal efficiency and reducing manual intervention costs. It is particularly suitable for closed or semi-closed water environments requiring long-term maintenance, providing an intelligent and automated solution for water environment protection and management.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problems of the inability of the enclosure sewage discharge structure to dynamically adjust the sewage discharge direction according to wind direction, low pollutant removal efficiency, and low energy utilization, this invention provides an automatic sewage discharge system and dynamic sewage discharge method for enclosures. This system can adaptively optimize the sewage discharge strategy according to pollutant distribution and meteorological conditions, thereby improving pollutant removal efficiency and reducing the cost of manual intervention.

[0021] Please see Figures 1 to 4In a first aspect, embodiments of this application provide an automatic sewage discharge system for enclosures, including at least three enclosure components 1, a sewage discharge drive 2, a water surface pollution monitoring device, a wind direction and wind force measuring device 3, and a control unit; each enclosure component 1 includes an enclosure body 11, an isolation component 12, and a filter component 13. At least three enclosure bodies 11 are connected end-to-end in sequence to form a closed area 101 for containing water. A sewage discharge port 114 communicating with the closed area is provided on the side wall of the enclosure body 11. Both the isolation component 12 and the filter component 13 are movably installed on the enclosure body 11 and are positioned corresponding to the sewage discharge port 114; the sewage discharge drive 2 includes a first drive component 21 and a second drive component 22. The first drive component 21 is driven to the isolation component 12 and is used to drive the isolation component 12 to open and close the sewage outlet 114; the second drive component 22 is driven to the filter component 13 and is used to drive the filter component 13 to switch between a filtration position covering the sewage outlet 114 and a storage position away from the sewage outlet 114; the water surface pollution monitoring equipment is located in the closed area 101 and is used to monitor water surface pollutants; the wind direction and wind force measuring device 3 is located in the enclosure component 1 and is used to monitor wind direction and wind force; the control unit is electrically connected to the first drive component 21, the second drive component 22, the water surface pollution monitoring equipment and the wind direction and wind force measuring device 3, and is used to receive pollutant status and environmental wind direction and wind force data, and decide whether to start sewage discharge based on the preset sewage discharge threshold.

[0022] In this device, a closed enclosure area can be constructed by setting up enclosure component 1, water surface pollution monitoring equipment and wind direction and wind force measuring device 3. An isolation element 12 and a filter element 13 are installed at the sewage outlet 114 of each enclosure main body 11. The isolation element 12 is controlled by the first driving element 21, which can open and close the sewage outlet 114. In the non-sewage discharge state, the sewage outlet 114 is kept closed to prevent external pollutants from entering the closed area 101 or the internal water from leaking out. When sewage discharge is required, the sewage outlet 114 is opened. At the same time, the filter element 13 can switch between the filtration position and the storage position under the action of the second driving element 22. When sewage discharge is required, the filter element 13 of the enclosure component 1 located on the downwind side can be switched to the storage position to fully open the sewage outlet 114 located on the downwind side, so as to facilitate the centralized discharge of pollutants accumulated in the closed area 101. The filter element 13 of the enclosure component 1 located in other positions is switched to the filtration position to cover the corresponding sewage outlet 114 and filter the water to prevent external pollutants from entering the enclosure area with the water flow. At the same time, it will not block the wind to push the water flow to carry pollutants to the sewage outlet 114. The water surface pollution monitoring equipment monitors the pollutant situation on the water surface within the closed area 101 in real time. When the pollutants on the water surface reach the preset discharge standard, the control unit can accurately determine the downwind location of the enclosure component 1 by combining the environmental data obtained by the wind direction and wind force measuring device 3. This allows the control unit to open the isolation component 12 via the first drive component 21 of the corresponding downwind enclosure component 1, while simultaneously controlling the second drive component 22 to switch the filter component 13 at that location to the storage position, making the discharge outlet 114 fully open. At this time, the water within the closed area 101, propelled by the wind, carries pollutants towards the discharge outlet 114, achieving directional discharge. For enclosure components 1 in other locations, the control unit controls the second drive component 22 to switch the filter component 13 to the filtration position, covering the upstream position of the discharge outlet 114. The filter component 13 blocks external pollutants from entering while allowing clean water to flow into the closed area 101 through the filter component 13, maintaining the dynamic balance of the water within the area. The entire sewage discharge process requires no human intervention. The control unit automatically makes decisions and executes based on real-time monitoring data, which not only improves sewage discharge efficiency but also ensures the stability of the water environment within the enclosed area. It is especially suitable for local pollution control scenarios in open water areas such as lakes and rivers.

[0023] Preferably, please refer to Figures 1 to 4In this embodiment, three sets of enclosure bodies 11 are provided, and two adjacent enclosure bodies 11 are connected by fasteners 4 to form a closed area 101 of an equilateral triangle. The control unit is configured to: receive and process monitoring data from the water surface pollution monitoring equipment and the wind direction and force measuring device; when it is determined that the water surface pollutants have reached the preset discharge standard, determine a target enclosure body 11 located downwind based on the real-time wind direction; control the first drive component 21 and the second drive component 22 corresponding to the target enclosure body 11 to operate synchronously, thereby opening the isolation component 12 and driving the filter component 13 to move to the storage position, fully opening the discharge port 114 of the target enclosure body 11; simultaneously, control the first drive components 21 corresponding to the other two non-target enclosure bodies 11. The action opens the isolation component 12, while the second drive component 22 of the non-target enclosure body 11 keeps the filter element 13 in the filtering position. This ensures that the discharge port 114, even when open, still has the interception function of the filter element 13, preventing external pollutants from entering the closed area 101 through these discharge ports 114. At the same time, it allows water that meets the filtration standards to flow in, maintaining the normal circulation of water within the closed area 101. Finally, natural wind power is used to drive the surface pollutants towards the target enclosure body 11 and discharge them into the closed area 101 through its discharge port 114 and filter element 13. This group control method can take into account both the isolation and protection of the area and the water renewal needs during directional sewage discharge. Through the equilateral triangle structural design, the three enclosure bodies 11 form a stable support structure in spatial distribution. When any one enclosure body 11 is the target discharge port 114, the other two enclosure bodies 11 can be in a relatively upwind or crosswind position, thereby more effectively using wind power to push pollutants towards the target discharge port 114. Meanwhile, the equilateral triangular layout ensures that the distance between any two enclosure bodies 11 is equal, facilitating the uniform movement of pollutants towards the target discharge outlet 114 under wind force, and preventing localized pollutant accumulation. Furthermore, the closed area 101 of the equilateral triangle minimizes the use of enclosure materials and drive modules, reducing the overall construction cost and installation difficulty, while ensuring the stability and wind resistance of the enclosed area, maintaining structural integrity under different wind directions and forces. After discharge, the control unit, based on feedback from the water surface pollution monitoring equipment, if the pollutant levels are below the preset discharge standard, controls the first drive unit 21 of all enclosure bodies 11 to close the isolation component 12, and the second drive unit 22 to reset the filter component 13 to its filtering position, restoring the overall closed state of the closed area 101 and continuing to isolate and protect the internal water.

[0024] It should be noted that this solution does not impose specific restrictions on the number and shape of the enclosure bodies 11, and their number and shape can be adjusted adaptively. For example, depending on the area and shape requirements of the actual treated water area, the enclosure bodies 11 can be set to four, five, or even more groups, jointly enclosing a polygonal closed area 101 such as a square or regular pentagon, to better adapt to the boundary contours of different water areas. When the number of enclosure bodies 11 increases, the decision logic of the control unit will also be optimized accordingly. Through precise analysis of wind direction and wind force data, the optimal downwind and upwind target sewage outlets 114 are determined from multiple enclosure bodies 11, and the isolation component 12 of the downwind target sewage outlet 114 is switched to the open state, while the filter component 13 is in the retracted position. Meanwhile, the isolation component 12 of the upwind target sewage outlet 114 is switched to the open state, while the filter component 13 is in the filtering position. The positions of the isolation components 12 and filter components 13 of other sewage outlets 114 remain unchanged.

[0025] When the water surface pollutants are determined to have reached the preset discharge standard, insufficient natural wind may occur when the automatic discharge program is activated. To resolve this issue, please refer to [link to relevant documentation]. Figures 1 to 5In some possible embodiments, the system further includes three sets of wind compensation devices 5, each set corresponding to a enclosure body 11, for generating compensating airflow in the same direction as the ambient wind. Specifically, the wind compensation device 5 includes a rotary drive mechanism 51 and at least one fan unit 52. In this embodiment, the fan unit 52 is an axial flow fan, with its outlet direction perpendicular to the extension direction of the enclosure body 11 and facing the inside of the closed area 101. The rotary drive mechanism 51 is an electric rotating shaft. Two sets of fan units 52 are provided, installed side by side on the inside of the filter element 13, each connected to the top of the filter element 13 via a separate electric rotating shaft. The fan units 52 are located inside the filter element 13. When the ambient wind force is lower than a preset threshold, the control unit can activate the wind compensation device 5 of the corresponding enclosure body 11 based on the wind direction data. The rotary drive mechanism 51 drives the fan unit 52 to adjust to the same angle as the ambient wind direction. After the two sets of axial flow fans start synchronously, they blow directional airflow into the inner side of the closed area 101, forming an auxiliary driving force in the same direction as the natural wind. This auxiliary airflow can enhance the flow speed of the water in the closed area 101, pushing pollutants that would otherwise be difficult to accumulate due to insufficient wind towards the target discharge outlet 114, preventing pollutants from spreading and lingering in the area. The control unit can dynamically adjust the output power of the fan unit 52 according to the actual value of the ambient wind force and is equipped with a stepped control program. When the ambient wind force reaches level 5 or above, the wind compensation device 5 automatically shuts off, relying entirely on natural wind power to drive the sewage discharge; when the wind force is between level 3 and 5, the power is adjusted to 30%-50%, using low-power operation to assist natural wind in enhancing water flow dynamics; when the wind force is below level 3, the power is increased to 60%-80%, using high-intensity airflow to form a directional driving force, ensuring that pollutants can effectively gather towards the target sewage outlet 114.

[0026] Preferably, in this embodiment, the water surface pollution monitoring equipment employs one or more of the following: a hyperspectral imager, a visible light camera, or a lidar (LiDAR) system. A hyperspectral imager captures the reflectance spectra of the water surface in multiple narrow bands, enabling the identification of spectral characteristics of pollutants such as oil films and algal aggregates. A visible light camera, equipped with a high-resolution camera, allows for rapid surface inspection by drones, visually identifying pollution through color changes (such as turbidity, foam, and oil). LiDAR measures water surface morphology and ripple changes by emitting laser beams, indirectly inferring the presence of surface coverings (such as oil films or floating algal layers). The wind direction and wind force measurement device 3 employs a combination of a wind direction sensor and a wind force sensor. The wind direction sensor detects the wind direction angle and can output real-time wind direction data from 0 to 360 degrees with an accuracy of ±1 degree. The wind force sensor measures wind speed, covering a range of 0.5-60 meters per second with a resolution of 0.1 meters per second. Both are connected to the control unit via waterproof cables.

[0027] To improve the comprehensiveness of the water environment assessment within the closed area 101, in some possible embodiments, the system also includes an oxygen monitoring device. This device is located within the closed area 101 and connected to the control unit to monitor the dissolved oxygen content in the water. When the dissolved oxygen content is lower than a preset dissolved oxygen threshold, the control unit controls all first drive components 21 to activate all isolation components 12 for water exchange. In practical applications, when the dissolved oxygen content is detected to be lower than the preset dissolved oxygen threshold and pollutants reach the preset discharge standard, the control unit will prioritize the discharge procedure. First, it determines the target discharge outlet 114 using wind direction and force data, activates the corresponding isolation component 12, and switches the filter component 13 to the receiving position to centrally discharge pollutants. After the pollutant concentration drops to a safe range, all isolation components 12 remain open, while the filter components 13 at non-target discharge outlets 114 are kept in their filtration positions. Natural wind or the wind compensation device 5 is used to propel clean external water through the filter components 13 into the closed area 101, achieving water exchange to increase the dissolved oxygen content until it rises above the preset threshold. If the dissolved oxygen content remains below the threshold, the control unit can also activate the auxiliary aeration device to further increase the dissolved oxygen level by introducing air into the water until the monitoring data returns to normal. Then, the isolation element 12 is closed and the filter element 13 is reset to restore the isolation state of the closed area 101.

[0028] To secure the main body 11 of the enclosure and ensure its stability, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 4 and Figure 7 In some possible embodiments, the automatic sewage discharge system for the enclosure also includes three fixing members 4. Preferably, in this embodiment, the fixing member 4 adopts a cylindrical rod structure, and the lower end of the fixing member 4 is provided with an anchoring part for insertion into the bottom of the water. The anchoring part has a conical structure and can be quickly inserted into the bottom soil to achieve initial fixation. The three fixing members 4 are respectively set at the connection between two adjacent enclosure bodies 11, and the side of the enclosure body 11 is slidably connected to the fixing member 4.

[0029] Please see Figures 1 to 5Preferably, in this embodiment, the main body 11 of the enclosure includes a flexible curtain, a counterweight 112, and a rigid enclosure component 113; the flexible curtain is made of high-strength composite nylon material, and its two sides are sleeved on the outside of the fixing component 4, allowing it to slide on the fixing component 4; the counterweight 112 is made of multiple high-density concrete blocks or cast iron blocks, which are arranged sequentially or intermittently along the bottom edge of the flexible curtain to increase the weight at the bottom of the flexible curtain, so that the curtain can maintain a vertical state in the water and avoid floating or tilting due to water flow impact or wind force. The rigid enclosure 113 adopts a waterproof plate-like structure and is made of lightweight and high-strength aluminum alloy plate. The bottom of the rigid enclosure 113 is fixedly and sealed to the upper edge of the flexible curtain in sequence. Its width matches the width of the flexible curtain. A sliding sleeve is provided between two adjacent rigid enclosures 113. The sliding sleeve is sleeved on the outside of the fixing member 4 and fixedly connected to the end of the rigid enclosure 113, so that adjacent rigid enclosures 113 can slide along the axial direction of the fixing member 4 through the sliding sleeve, thereby adapting to the height adjustment requirements of the enclosure body 11 caused by different water level changes. The drain outlet 114 is located at the top of the rigid enclosure 113. The inner side of the rigid enclosure 113 has a vertically extending guide groove. The filter element 13 uses a high-density polyester fiber filter screen with a pore size of 0.1-0.3 mm, effectively intercepting suspended particulate matter, algae, and other pollutants in the water while allowing water molecules and dissolved oxygen to pass through. The bottom of the filter element 13 is embedded in the guide groove and can slide up and down along the guide groove under the drive of the second drive element 22, switching between the filtering and storage positions. When the filter element 13 is in the filtering position, it slides into the drain outlet 114 of the guide groove, forming a complete coverage of the drain outlet 114. When switched to the storage position, the filter element 13 slides downwards into the guide groove, completely detaching from the drain outlet 114 area, avoiding obstruction of the sewage discharge process. A guide rail 115 is provided on the top outer side of the enclosure body 11, corresponding to the position of the sewage outlet 114. An isolator 12 is located at the bottom of the guide rail 115. It has a plate-like structure and is made of the same material as the enclosure body 11, allowing it to slide laterally on the outer side of the enclosure body 11. The sliding direction of the isolator 12 is consistent with the extension direction of the sewage outlet 114. When the first drive unit 21 receives a command from the control unit, it drives the isolator 12 to slide along the guide rail 115 to open and close the sewage outlet 114. Each isolator 12 has a buoyancy component 6 arranged along its length on its outer side. The buoyancy component 6 is a series of sealed airbags, each filled with inert gas, providing excellent buoyancy. The height of the buoyancy component 6 is consistent with the central axis of the isolator 12. The buoyancy it generates balances the weight of the isolator 12 in the water, allowing it to maintain a stable position near the water surface, preventing it from sinking due to its own weight or being displaced by water flow, thus ensuring the accuracy of the opening and closing of the sewage outlet 114.

[0030] Further, please refer to Figures 1 to 5 Each fixing component 4 is equipped with a winding load-bearing structure 7, which includes a winding motor 71 and a winding reel 72. The winding reel 72 is rotatably connected to the fixing component 4 via bearings. The output shaft of the winding motor 71 is fixedly connected to the central shaft of the winding reel 72, and is used to drive the winding reel 72 to rotate forward and backward. A high-strength nylon rope is wound on the winding reel 72. One end of the rope is fixedly connected to the top of the two adjacent enclosure bodies 11, and the other end is wound on the winding reel 72. By rotating the winding motor 71 forward and backward, the rope can drive the enclosure body 11 to move up and down along the axial direction of the fixing component 4, thereby enabling dynamic height adjustment of the enclosure body 11 under different water level conditions in conjunction with the buoyancy component 6. When the water level rises, the winding motor 71 rotates in the forward direction to wind up the rope. At the same time, the main body of the enclosure 11 rises with the water level under the action of the buoyancy component 6. At this time, the main body of the enclosure 11 is also traction and positioning by the winding rope. When the water level drops, the winding motor 71 rotates in the reverse direction to release the rope. The main body of the enclosure 11 slides down along the fixing member 4 under the action of gravity. The flexible enclosure member 111 is flexible and can hang down naturally with the water level, always adhering to the bottom surface.

[0031] Please see Figure 1 , Figure 6 and Figure 8 To achieve precise drive control of the isolator 12 and filter element 13, in some possible embodiments, the first drive element 21 adopts a screw drive mechanism, which includes a drive motor 211, a screw 212, and a slider 213. The slider 213 is fixedly connected to the isolator 12. The screw 212 is arranged along the extension direction of the guide rail 115. The drive motor 211 is connected to the screw 212 through a coupling. When the control unit issues an opening / closing command, the drive motor 211 drives the screw 212 to rotate forward or reverse, thereby driving the slider 213 to slide along the screw 212, realizing the lateral movement of the isolator 12 to open or close the drain port 114. The second drive element 22 adopts one of a cylinder, a hydraulic cylinder, or an electric push rod. Its cylinder body is fixed to the inner sidewall of the rigid enclosure 113 on both sides of the filter element 13, and the end of the piston rod is connected to the bottom sides of the filter element 13. When the control unit needs to switch the filter element 13 to the filtering position, the piston rod of the second drive element 22 retracts, driving the filter element 13 to slide upward along the guide groove to the filtering position, covering the upstream of the drain outlet 114; when the piston rod extends, it pushes the filter element 13 to slide downward along the guide groove to the storage position, completely separating it from the area of ​​the drain outlet 114.

[0032] Secondly, embodiments of this application also provide a dynamic sewage discharge method, using an automatic sewage discharge system for enclosures as described in any of the above embodiments, the method comprising: S1. Deploy the automatic sewage discharge system of the enclosure in the target water area, continuously monitor the water surface pollutants in the closed area 101 through the water surface pollution monitoring equipment, and collect environmental wind direction and wind force data in real time through the wind direction and wind force measurement device. S2. The control unit receives monitoring data and starts the automatic discharge program when it determines that the pollutants on the water surface have reached the preset discharge standard. S3. The control unit determines the target sewage discharge side located downwind based on the real-time wind direction; S4. Control the isolation element 12 and filter element 13 corresponding to the target sewage discharge edge to open synchronously, forming a filtration sewage discharge channel; at the same time, control the isolation element 12 on other non-target enclosure edges to open. S5. Under the action of natural wind, pollutants on the water surface gather towards the target discharge edge and are discharged into the closed area 101 through the filter discharge channel.

[0033] In some possible embodiments, during the initiation of the automatic sewage discharge procedure, the control unit simultaneously acquires real-time wind force data; if the real-time wind force is less than the preset wind force value, the wind force compensation device 5 located on at least one enclosure body 11 in the upwind direction is activated, and it is controlled to generate a compensation airflow in the same direction as the natural wind to assist in driving the pollutants; if the real-time wind force is greater than or equal to the preset wind force value, the sewage discharge is completed solely by natural wind force.

[0034] In some possible embodiments, the control unit is also equipped with a wind monitoring and control program that acquires pollutant data from the water surface pollution monitoring equipment when the wind speed reaches a set level. If the pollutant data reaches 50% of the preset discharge standard, the aforementioned automatic discharge program is activated. The set level is level 5 or higher.

[0035] Furthermore, the present invention provides another specific embodiment, which includes the following steps: Step 1: First, based on the pollution range and topography of the target water area, vertically anchor three cone-shaped fixing components 4 in an equilateral triangle arrangement to the bottom of the water. Next, install three enclosure components 1: place a flexible curtain with counterweights onto the fixing components 4, and then connect and seal the rigid enclosure component 113 to the fixing components 4 via a sliding sleeve. Finally, install the surface pollution monitor and wind direction and speed sensors, connect them to the control unit, complete system self-testing and preset key data such as discharge thresholds and wind compensation parameters, and put the system into standby mode.

[0036] Step 2: The system enters normal operation mode. The water surface pollution monitoring equipment continuously scans the water surface within the closed area 101, and the wind direction and wind speed measuring device 3 continuously measures the real-time wind direction and wind speed. The oxygen monitoring equipment continuously monitors the dissolved oxygen content of the water. The control unit receives and processes the above monitoring data in real time.

[0037] When analysis reveals that the concentration of pollutants on the water surface reaches or exceeds the preset discharge threshold, the system determines that an automatic discharge procedure needs to be initiated, proceeding to step three. If the dissolved oxygen content is below the preset threshold, but the pollutant concentration is not excessive, the system can initiate an aeration procedure independently, activating all isolation components 12 for water exchange, or activating auxiliary aeration devices. The wind monitoring and control program within the control unit continues to operate. When a wind speed of level 5 or above is detected, even if the pollutant concentration only reaches 50% of the preset standard, an early warning is triggered, and preparations are made to initiate the discharge procedure to utilize strong winds for efficient discharge.

[0038] Step 3: Based on real-time wind direction data and the geographical location of the equilateral triangle enclosed area, the control unit calculates which side of the enclosure is downwind and designates it as the target sewage discharge side. The corresponding enclosure component 1 is the target enclosure body 11. Simultaneously, the control unit assesses real-time wind force data. If the wind force is lower than a preset compensation threshold, it prepares to activate the wind compensation device 5 on one or more enclosure bodies 11 on the upwind side of the target sewage discharge side.

[0039] Step 4: After determining the strategy, the control unit sends a command to the target enclosure body 11. The first drive component 21 corresponding to the target enclosure body 11 is activated, driving the isolating component 12 to slide along the guide rail 115, fully opening the drain outlet 114. Simultaneously, its second drive component 22 is activated, driving the filter component 13 to slide downwards along the guide groove to the storage position, completely removing it from the drain outlet 114 area. At this time, the target drain outlet 114 is in a fully open state, forming an unobstructed drain channel.

[0040] The control unit sends commands to the enclosure bodies 11 of the other two non-target sides. Their first drive units 21 activate, opening their respective isolation sections 12. Their second drive units 22 remain stationary or switch to a filtering position, causing a high-density polyester fiber filter to cover the upstream side of the drain outlet 114. This enables the two non-target sides to have filtering functionality while open.

[0041] If wind compensation is determined to be required in step three, the control unit activates the wind compensation device 5 on the upwind enclosure body 11. The rotary drive mechanism 51 adjusts the air outlet direction of the fan unit 52 to be consistent with the ambient wind direction, and starts the fan according to the preset stepped power to blow auxiliary airflow into the closed area 101.

[0042] Step 5: Driven by the wind, the polluted water within the enclosed area begins to gather and discharge downwind through the open discharge outlet 114. Throughout the process, sensors continuously report changes in pollutant concentration. When the control unit determines that the pollutant concentration has dropped to a safe level, the discharge is complete. Subsequently, the system automatically instructs all isolation components 12 to close, all filters to return to their filtering positions, and the wind compensation device 5 to shut down, restoring the entire enclosure system to a fully enclosed monitoring and protection state, awaiting the next instruction.

[0043] Step 6: If monitoring reveals that the dissolved oxygen content in the water is too low but the pollutants do not exceed the standard, the system can automatically switch to water exchange and oxygenation mode: open all isolation components 12, keep the filter screen working, use the water flow for natural exchange or start the special aeration device to increase dissolved oxygen, and close the system after the water quality returns to normal.
