Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, and in particular to a floating platform for cleaning waste in an anaerobic pond of a sewage treatment plant. Background Technology

[0002] When treating floating debris in wastewater treatment plants, the water is filtered through coarse and fine screens. While larger debris is generally filtered out, small plastics, paper objects, and fine fibers often float in the anaerobic tank. These materials are difficult to nitrify and flocculate. These small floating objects are difficult to remove from the pipes leading to the next aerobic tank, which are several meters below the wastewater surface. They also float in the anaerobic tank, affecting its appearance and often requiring manual removal with nets, which is time-consuming and labor-intensive. Therefore, there is a need for a floating platform for cleaning debris in the anaerobic tanks of wastewater treatment plants, which can solve the problem of manually removing floating debris with nets in existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide a floating platform for cleaning waste in anaerobic ponds of sewage treatment plants, which can solve the problem that in the prior art, floating waste in anaerobic ponds needs to be manually cleaned with nets.

[0004] This invention is implemented as follows:

[0005] A floating platform for waste removal in an anaerobic tank of a wastewater treatment plant includes a floating platform installed within the anaerobic tank. The floating platform comprises a drain pipe, a floating body assembly, a floating and moving assembly, a pumping pipe, a water-receiving platform, a wastewater pump, a multi-stage filtration assembly, and a water-receiving platform shell. Several sets of floating and moving assemblies are circumferentially arranged on the sides of the floating body assembly, allowing the floating body assembly to float on the water surface of the anaerobic tank. The water-receiving platform shell is fixedly located above the center of the floating body assembly, with the water-receiving platform positioned on top of the shell. The multi-stage filtration assembly is located between the water-receiving platform and the outer shell of the water-receiving platform. On the shell; several sewage pumps are respectively installed on the floating body assembly and arranged circumferentially below the outer shell of the water receiving platform; each sewage pump is connected to a pumping pipe, and the lower part of each pumping pipe is fixed to the floating body assembly, so that the lower end of the pumping pipe extends below the water surface, and the upper end of the pumping pipe passes through the outer shell of the water receiving platform and the water receiving platform and extends to the top of the multi-stage filtration assembly, so that the sewage in the anaerobic tank of the sewage treatment plant is discharged into the multi-stage filtration assembly through the sewage pumps and pumping pipes; the upper ends of several drain pipes are respectively connected to the bottom of the outer shell of the water receiving platform, and the lower ends of several drain pipes are respectively fixed to the top side of the floating body assembly.

[0006] The floating assembly includes float one, a transmission channel, and float two. Several floats are circumferentially distributed on the outside of float two, and several floats one are connected to float two through the transmission channel. The outer shell of the water receiving platform is fixed to the several transmission channels by several support plates, so that the outer shell of the water receiving platform is positioned above float two. Several sets of floating and traveling components are respectively set on the sides of several floats one away from float two. Several drainage pipes are respectively fixed on the top of several floats one. Several sewage pumps are respectively fixed on float two, and the water pumping pipe is fixed on the side wall of float two.

[0007] Each set of floating propulsion components includes a laser rangefinder, an impeller, a motor, a control mechanism, and a battery. The control mechanism, battery, and motor are all located inside float one. The laser rangefinder is embedded in the side wall of float one away from float two and faces the wall of the anaerobic tank of the wastewater treatment plant. The output end of the laser rangefinder is electrically connected to the input end of the control mechanism and battery. The input end of the motor is electrically connected to the output end of the control mechanism and battery. The output shaft of the motor can rotatably extend to the side wall of float one away from float two and is coaxially fixed to the impeller. The impeller is located in the water of the anaerobic tank of the wastewater treatment plant.

[0008] The top of the first float is provided with a solar panel, which is electrically connected to the control mechanism and the battery; a lighting lamp is embedded in the side wall of the first float away from the second float, and the lighting lamp is electrically connected to the control mechanism and the battery.

[0009] The outer circumference of each of the aforementioned floats is provided with an annular anti-collision ring, and the anti-collision ring has a notch corresponding to the groove where the impeller is installed.

[0010] The top of the anti-collision ring has several greening holes spaced apart, and air-purifying plants are planted in the greening holes.

[0011] The second float is equipped with a control and data processing module. A second solar panel is located in the center of the top surface of the water-receiving platform. The second solar panel is electrically connected to the power supply terminal of the control and data processing module. The control and data processing module is electrically connected to the sewage pump and the floating propulsion component through a data transmission interface, and is also connected to the signal receiving equipment of the sewage treatment plant.

[0012] The control and data processing module is detachably equipped with a cover. Several heat dissipation components are spaced apart between the control and data processing module and the cover, and these heat dissipation components extend to the outside of the control and data processing module. The bottom of the control and data processing module is equipped with a partition, which is composed of multiple shock-absorbing pads stacked and fixed in the middle of the float and located below the outer shell of the water-receiving platform.

[0013] The multi-stage filtration assembly includes filter grids, drainage platforms, fine hanging particles, guide plates, irregular needles, and a drainage platform. Several filter grids are spaced apart and embedded in the drainage platform. Several pumping pipes extend through the drainage platform and then pass above the middle of several filter grids, ensuring the upper ends of the pumping pipes are higher than the filter grids. Funnel-shaped drainage platforms are installed at the bottom of each filter grid. Several fine hanging particles are spaced apart on the sidewalls of the funnel-shaped drainage platform shell, corresponding to the outlet ends of the drainage platforms. Drainage platforms and guide plates are located at the bottom of the drainage platform shell, between the fine hanging particles. The guide plate is positioned above the drainage platform, which is located above the upper end of the drain pipe. Irregular needles are located in the middle of the drainage platform. Several baffles are spaced apart around the irregular needles in the middle of the guide plate. Water-permeable holes are evenly distributed around the irregular needles on the drainage platform.

[0014] The filter grid has several outlets spaced apart at its edge, and the diameter of the outlets is larger than the size of the filter grid.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Because the present invention is equipped with a floating movement component, the garbage cleaning floating platform can float in the anaerobic tank of the sewage treatment plant and move freely. It can suck in and filter the sewage containing floating small plastics, paper objects and fine fibers in the anaerobic tank and then discharge it, reducing the difficulty of subsequent flocculation and improving the treatment efficiency.

[0017] 2. Because the present invention is equipped with multiple filtration components and anti-collision rings, the multiple filtration components can perform four-stage filtration of sewage through filter grids, fine hanging particles, irregular needles and water permeable holes, ensuring effective filtration of floating fine plastics, paper objects, fine fibers and other debris in the anaerobic tank of the sewage treatment plant. At the same time, the green plants planted in the greening holes of the anti-collision ring play a certain role in purifying the surface of sewage in the anaerobic tank of the sewage treatment plant.

[0018] 3. This invention can be charged by sunlight, which is energy-saving and environmentally friendly. Furthermore, a small GPS system is incorporated into the control and data processing module, which can automatically navigate back to the maintenance station after the garbage collection floating platform is full of garbage. It can be used in other water treatment applications, as well as in the cleaning of floating garbage in rivers and seas. Attached Figure Description

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Please see the appendix Figure 1 To be continued Figure 6A waste collection floating platform for an anaerobic tank in a wastewater treatment plant includes a waste collection floating platform 100 floating within an anaerobic tank 37 of the wastewater treatment plant. The waste collection floating platform 100 includes a drain pipe 2, a floating body assembly, a floating and moving assembly, a pumping pipe 11, a water receiving platform 16, a wastewater pump 22, a multi-stage filtration assembly, and a water receiving platform shell 34. Several sets of floating and moving assemblies are circumferentially arranged on the sides of the floating body assembly, allowing the floating body assembly to float on the water surface of the anaerobic tank 37 via the floating and moving assemblies. The water receiving platform shell 34 is fixedly arranged above the middle of the floating body assembly, and the water receiving platform 16 is located on top of the water receiving platform shell 34. The multi-stage filtration assembly is arranged between the water receiving platform 16 and the water receiving platform shell. 34; Several sewage pumps 22 are respectively installed on the floating body assembly and arranged circumferentially below the water receiving platform shell 34; each sewage pump 22 is connected to a pumping pipe 11, the lower part of each pumping pipe 11 is fixed on the floating body assembly, so that the lower end of the pumping pipe 11 extends below the water surface, and the upper end of the pumping pipe 11 passes through the water receiving platform shell 34 and the water receiving platform 16 and extends to the top of the multi-stage filtration assembly, so that the sewage in the anaerobic tank 37 of the sewage treatment plant is discharged into the multi-stage filtration assembly through the sewage pump 22 and the pumping pipe 11; the upper ends of several drain pipes 2 are respectively connected to the bottom of the water receiving platform shell 34, and the lower ends of several drain pipes 2 are respectively fixed to the top side of the floating body assembly.

[0043] Preferably, four sewage pumps 22 can be installed, and four corresponding pumping pipes 11 can be installed along the four directions of east, south, west, and north. The lower end of the pumping pipes 11 can form bidirectional bi-directional branching pipes, as shown in the attached diagram. Figure 9 As shown, this ensures that water is pumped from all directions within the anaerobic tank 37 of the wastewater treatment plant, and that it is purified efficiently after being filtered through multiple filtration components. The model and specifications of the wastewater pump 22 and the diameter of the pumping pipe 11 can be selected according to the wastewater conditions and pumping flow rate within the anaerobic tank 37 of the wastewater treatment plant, so that the pump can deliver water to the top of the receiving platform 16.

[0044] Water pumped from the anaerobic tank 37 of the wastewater treatment plant is pumped to the top of the receiving platform 16. As the water flows down from the receiving platform 16 to the outer shell 34, it undergoes multiple filtration processes through a multi-stage filtration system, effectively filtering out floating debris. The filtered water is then discharged back into the anaerobic tank 37 through the drain pipe 2. The diameter and number of drain pipes 2 can be adapted to the drainage flow requirements. Preferably, one drain pipe 2 is installed in each of the four directions: east, south, west, and north. The ends of the drain pipes 2 form two branch pipes for efficient drainage.

[0045] When installing the pumping pipe 11 and the draining pipe 2, the buoyancy of the water and the weight of the garbage cleaning floating platform 100 are combined to ensure that the lower end of the pumping pipe 11 is below the water surface and the lower end of the draining pipe 2 is above the water surface, thereby ensuring the normal use of the pumping and draining functions.

[0046] The low density of the floating components allows the waste collection platform 100 to generate sufficient buoyancy when placed on the water surface, preventing it from sinking. The floating propulsion component propels the waste collection platform 100 to float and move in the water, thereby effectively cleaning floating waste in different locations within the anaerobic tank 37 of the wastewater treatment plant. This can replace manual water cleaning with nets, making the operation more efficient and convenient.

[0047] Please see the appendix Figure 2 To be continued Figure 6 The floating assembly includes a first float 4, a transmission channel 10, and a second float 23. Several first floats 4 are circumferentially distributed on the outside of the second float 23. Several first floats 4 are connected to the second float 23 through the transmission channel 10 via multiple connectors 12. The water receiving platform shell 34 is fixed to the transmission channel 10 via several support plates 24 and multiple connectors 23, so that the water receiving platform shell 34 is positioned above the second float 23. Several sets of floating and traveling components are respectively positioned on the side of several first floats 4 away from the second float 23. Several drain pipes 2 are respectively fixed to the top of several first floats 4 via fixing brackets 1. Several sewage pumps 22 are respectively fixed to the second float 23 via fixing brackets 30. The water pumping pipe 11 is fixed to the side wall of the second float 23 via connectors 314 and fixing brackets 25.

[0048] Float 1 (4) and Float 2 (23) should be made of low-density, high-strength foam plastic to support the weight of the garbage collection platform 100 and the buoyancy of the sewage. The transmission channel 10 can be hollow for laying data cables, etc., to ensure the safety and reliability of electrical connection nodes; the mechanical connection parts of the transmission channel 10 can be solid to ensure the robustness of the mechanical connection.

[0049] Preferably, four floats 4 can be provided, and slots for inserting the transmission channel 10 can be formed inside floats 4 and floats 23, so that the four floats 4 are respectively arranged in the four directions of east, west, south and north of floats 23, as shown in the attached figure. Figure 9 As shown, four sets of floating propulsion components, four drainage pipes 2 and four water pumping pipes 11 are set accordingly.

[0050] When using the device, the water flow rate needs to be adjusted according to the size of the device. Combined with the weight of the device itself and the buoyancy of float 14 and float 23, the center of gravity of the garbage cleaning platform 100 should be controlled at a relatively low position to prevent the garbage cleaning platform 100 from overturning when the wind is too strong nearby.

[0051] Preferably, the fixing device 20 can be made of aluminum alloy plate bent according to the size and shape of the sewage pump 22, and is used to press down the sewage pump 22. A soft pad can be set at the bottom of the fixing device 20 to reduce the impact of the operation vibration of the sewage pump 22 on the garbage cleaning floating platform 100.

[0052] Preferably, connector 12, connector 13, and connector 14 can all be bolts, with connector 13 connected to the solid part of the transmission channel 10. Fixing device 15 can be made of aluminum alloy plate bent according to the size of the drain pipe 11, and is used to fix the drain pipe 11.

[0053] Preferably, the fixing device 1 can be made of aluminum alloy plate bent according to the size and shape of the drain pipe 2, and can be fixed to the float 4 with double nails. If there is insufficient space, it can also be fixed with a single nail.

[0054] Please see the appendix Figure 2 To be continued Figure 6 Each set of floating propulsion components includes a laser rangefinder 6, an impeller 7, a motor 8, a control mechanism, and a battery 9. The control mechanism, battery 9, and motor 8 are all located inside the first float 4. The laser rangefinder 6 is embedded in the side wall of the first float 4 away from the second float 23 and faces the wall of the anaerobic tank 37 of the wastewater treatment plant. The output end of the laser rangefinder 6 is electrically connected to the input end of the control mechanism and battery 9. The input end of the motor 8 is electrically connected to the output end of the control mechanism and battery 9. The output shaft of the motor 8 extends rotatably through a sealed bearing to the side wall of the first float 4 away from the second float 23 and is coaxially fixed to the impeller 7. The impeller 7 is located in the water of the anaerobic tank 37 of the wastewater treatment plant. A groove is formed on the side wall of the first float 4 away from the second float 23 for the installation and rotation of the impeller 7, which is used to protect the impeller 7.

[0055] The laser rangefinder 6 emits a laser beam towards the wall of the anaerobic tank 37 of the wastewater treatment plant and receives the reflected laser beam, thereby calculating the distance between the floating propulsion component and the wall of the anaerobic tank 37. Through software programming control, the distance measured by the laser rangefinder 6 is sent to the sub-control mechanism and the sub-control mechanism of the battery 9. If the distance is too small, the sub-control mechanism can control the motor 8 to start, causing the motor 8 to drive the impeller 7 to rotate. The impeller 7 propels the water flow, and the reaction force of the water flow propels the garbage cleaning floating platform 100 away from the wall of the anaerobic tank 37, avoiding direct collision with the wall of the anaerobic tank 37.

[0056] The battery in the sub-control mechanism and battery 9 provides power to the motor 8 and the laser rangefinder 6. The motor 8 is preferably a motor with bidirectional rotation function, and the motor model and specifications can be selected according to actual usage requirements.

[0057] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 9 The top of the float 4 is provided with a solar panel 3, which is electrically connected to the control mechanism and the battery 9.

[0058] Solar panel 3 is used to convert solar energy into electrical energy and store it in the battery of the sub-control mechanism and battery 9 to power the motor 8 and laser rangefinder 6, which is energy-saving and environmentally friendly.

[0059] Please see the appendix Figure 2 and attached Figure 9 A lighting lamp 5 is embedded in the side wall of the float 4 away from the float 23. The lighting lamp 5 is electrically connected to the sub-control mechanism and the battery 9.

[0060] The sub-control mechanism and the battery 9 simultaneously provide power to the lighting lamp 5. Through software programming control, the sub-control mechanism and the battery 9 can control the lighting lamp 5 according to a preset time or preset brightness switch, which is convenient for lighting during nighttime operation.

[0061] The connecting cables for the sub-control mechanism and battery 9, the power cable for the motor 8, the power cable for the solar panel 3, and the power cable for the lighting 5 can be laid through the transmission channel 10.

[0062] Please see the appendix Figure 7 and attached Figure 8 The outer circumference of the plurality of floats 4 is provided with annular anti-collision rings 35, and the anti-collision rings 35 have notches corresponding to the grooves where the impellers 7 are installed.

[0063] The anti-collision ring 35 can be made of the same material as the float 4, or it can be made of a material with buffering and shock absorption properties according to actual use needs. The anti-collision ring 35 can be made into a ring structure, surrounding the four floats 4, to prevent the floats 4 from directly colliding with the walls of the anaerobic tank 37 of the sewage treatment plant.

[0064] The anti-collision ring 35 has four notches corresponding to the four grooves where the impeller 7 is installed, so as to ensure that the rotation of the impeller 7 can generate sufficient thrust on the water body, thereby ensuring that the water flow can generate sufficient reaction force to act on the garbage cleaning floating platform 100.

[0065] Please see the appendix Figure 7 and attached Figure 8 The top of the anti-collision ring 35 is formed with a plurality of greening holes 36 at intervals, and the greening holes 36 are planted with purifying green plants (not shown in the figure).

[0066] Preferably, the purifying plants can be selected adaptively according to the type of pollutants in the water body. These can include cattails, water hyacinths, etc., which can absorb pollutants such as phosphorus, nitrogen, COD, BODS, and suspended solids in wastewater, and also purify harmful substances such as arsenic, mercury, cadmium, and lead in the water. The number and diameter of the plant holes 36 can be adjusted adaptively according to actual planting needs.

[0067] Please see the appendix Figure 16 and attached Figure 18The float 23 is equipped with a control and data processing module 21 via multiple connectors 29. A solar panel 17 is provided in the middle of the top surface of the water receiving platform 16. The solar panel 17 is electrically connected to the power supply terminal of the control and data processing module 21. The control and data processing module 21 is electrically connected to the sewage pump 22 and the floating propulsion component via a data transmission interface 27, and is also connected to the signal receiving equipment of the sewage treatment plant.

[0068] The control and data processing module 21 has a built-in battery, and the solar panel 217 is used to convert solar energy into electrical energy and store it in the battery of the control and data processing module 21 to power the control and data processing module 21, which is energy-saving and environmentally friendly.

[0069] The control and data processing module 21 can be electrically connected to the sub-control mechanisms of the sewage pump 22 and the floating travel assembly, as well as the battery 9. It is used to collect distance data from each laser rangefinder 6, the operating status of each motor 8, etc., and to control the operation of the sewage pump 22 and the motor 8, achieving overall control of the entire waste-collecting floating platform 100. The form of the data transmission interface 27 can be selected according to the compatibility of the connection interface to ensure the reliability of signal transmission. Simultaneously, the control and data processing module 21 can be remotely wirelessly connected to the signal receiving equipment of the wastewater treatment plant, facilitating the monitoring and control of the operating status of the waste-collecting floating platform 100 by the plant's back-end staff.

[0070] Preferably, a small GPS system can be installed in the control and data processing module 21. After the garbage collection floating platform is full of garbage, the small GPS system can be controlled by the control and data processing module 21 to automatically navigate the garbage collection floating platform back to the maintenance station.

[0071] The control and data processing module 21 is detachably provided with a cover 39. Several heat sinks 26 are provided between the control and data processing module 21 and the cover 39. The heat sinks 26 extend to the outside of the control and data processing module 21 through small holes on the side wall of the control and data processing module 21.

[0072] The heat sink 26 facilitates the installation of the cover 39 on the control and data processing module 21 and also facilitates the dissipation of heat from the control and data processing module 21, ensuring the continuous, safe, and stable operation of the control and data processing module 21. The small holes in the heat sink 26 can be sealed with sealant to ensure waterproofing and prevent moisture damage to the control and data processing module 21.

[0073] Please see the appendix Figure 17 and attached Figure 18The bottom of the control and data processing module 21 is provided with a partition 28, which is composed of multiple shock-absorbing pads stacked together and fixed to the middle of the float 23 by the connector 4 29, and is located below the outer shell 34 of the water receiving platform.

[0074] Preferably, four shock-absorbing pads can be provided, using rubber pads, sponge pads, etc. The number and material of the shock-absorbing pads can also be adjusted according to the actual shock absorption needs, so as to play the role of shock absorption and moisture absorption, and provide protection for the control and data processing module 21.

[0075] Preferably, the connector 29 can be made of bolts to secure the control and data processing module 21 and the spacer 28 to the float 23.

[0076] Please see the appendix Figure 14 Appendix Figure 15 Appendix Figure 19 To be continued Figure 21 The multi-stage filtration assembly includes filter grids 19, drainage platforms 25, fine hanging particles 30, guide plates 31, irregular needles 32, and drainage platforms 33. Several filter grids 19 are spaced apart and embedded in the drainage platform 16. The upper ends of several pumping pipes 11 pass through the drainage platform 16 and then extend to the upper middle part of several filter grids 19, making the upper ends of the pumping pipes 11 slightly higher than the filter grids 19. A funnel-shaped drainage platform 25 is installed at the bottom of each filter grid 19, and several fine hanging particles 30 are spaced apart in the funnel-shaped drainage platform. On the side wall of the outer shell 34, and correspondingly located below the outlet of several drainage platforms 25; the drain platform 33 and the guide plate 31 are located at the bottom of the outer shell 34 of the water receiving platform and between several fine hanging particles 30, the guide plate 31 is located above the drain platform 33, and the drain platform 33 is located above the upper end of the drain pipe 2; the irregular needle 32 is located in the middle of the drain platform 33, and the middle of the guide plate 31 forms several baffles arranged at intervals around the irregular needle 32, and the drain platform 33 is evenly distributed with water permeable holes 38 around the irregular needle 32.

[0077] The filter grid 19 is adaptively arranged according to the positions of the four water pumping pipes 11 to ensure that the water at the top of the water pumping pipes 11 falls directly onto the filter grid 19. When selecting the power of the sewage pump 22, the water head sprayed from the top of the water pumping pipes 11 should not be too high, so as to ensure that the water falls onto the filter grid 19 after falling, achieving an effective filtration effect. At the same time, the solar panel 17 can be installed protruding from the top surface of the water receiving platform 16 to achieve a water-blocking effect, thereby maximizing the water flow through the filter grid 19 and falling into the drainage platform 25.

[0078] The size of the filter screen 19 can be adjusted according to the size of the debris in the wastewater, and is used for the first filtration of larger debris in the water. The funnel-shaped drainage platform 25 is used to collect and guide the water after the first filtration to the fine hanging particles 30. The fine hanging particles 30 can be made of multiple rows of small, long strip-shaped particles, and small debris or fibers are hung on the fine hanging particles 30 for the second filtration of smaller debris in the water.

[0079] The guide plate 31 can adopt a spherical structure, and its top can be connected to the side wall of the water receiving platform shell 34 and located below the fine hanging particles 30, so that the water after the second filtration flows to the guide plate 31. By using the spherical structure of the guide plate 31 to gather the water to the bottom of the spherical surface of the guide plate 31, and by using the baffle to limit and guide the flow, the water can flow through the irregular needle 32 and then flow to the leakage platform 33.

[0080] Preferably, the baffles on the guide plate 31 can be U-shaped, with one baffle in each of the four directions: east, south, west, and north. The open end of the U-shape faces the irregular needle 32, and the water flows through the gaps between adjacent baffles to the irregular needle 32. The irregular needle 32 can be composed of multiple columnar structures arranged at irregular intervals, thereby intercepting and filtering debris of different sizes, achieving the purpose of a third filtration. The higher the columnar structure is set, the more fine debris it can accommodate. The drain platform 33 can also adopt a spherical structure, stacked vertically with the guide plate 31 at intervals. The irregular needle 32 is located in the middle of the drain platform 33 and extends between the four baffles of the guide plate 31.

[0081] After the third filtration, the water flows out through the gaps in the columnar structure to the drain platform 33, and then flows from the small permeable holes 38 of the drain platform 33 to the bottom of the water receiving platform shell 34. The diameter of the permeable holes 38 can be adaptively adjusted according to the sewage filtration situation. The permeable holes 38 can perform a fourth interception and filtration of garbage in the water. The permeable holes 38 are arranged in a uniform or densely packed manner around the perimeter, etc., to quickly discharge the water to the bottom of the water receiving platform shell 34.

[0082] Water that has undergone four filtrations is discharged through a drain pipe 2 connected to the bottom of the water receiving platform housing 34. Since the water receiving platform housing 34 is positioned above the transmission channel 10 via a support plate 24 and is higher than the float 4, the end of the drain pipe 2 connected to the bottom of the water receiving platform housing 34 is higher, and the end of the drain pipe 2 located on the float 4 is lower, so that the drainage can be achieved by using the gravity of the water.

[0083] At the location where the water pumping pipe 11 penetrates the outer shell 34 of the water receiving platform, a sealing ring can be used to ensure the sealing of the connection between the water pumping pipe 11 and the reserved hole on the side wall of the outer shell 34 of the water receiving platform, so as to avoid water leakage from the gap.

[0084] Please see the appendix Figure 10 To be continued Figure 13The height of the support plate 24 can be adapted to the installation height of the water receiving platform shell 34, leaving installation space for the sewage pump 22, control and data processing module 21, etc. below the water receiving platform shell 34. In order to reduce the weight of the garbage cleaning floating platform 100, a hollow support plate 24 can be used. The part of the support plate 24 that connects to the transmission channel 10 is a solid structure to improve the connection reliability. The top of the support plate 24 is adapted to the shape of the side wall slope of the water receiving platform shell 34 to ensure the connection and support stability between the support plate 24 and the water receiving platform shell 34.

[0085] The filter grid 19 has several outlets 18 spaced apart at its edge, and the diameter of the outlets 18 is larger than the size of the filter grid 19.

[0086] Wastewater on the filter screen 19 can flow into the drainage platform 25 through the outlet 18. Due to the large diameter of the outlet 18, overflow can be achieved, preventing water accumulation on the top of the receiving platform 16. Preferably, the filter screen 19 has a square structure, and an outlet 18 can be provided at each of its four corners.

[0087] Please see the appendix Figure 1 To be continued Figure 21 The working process and working principle of this invention are as follows:

[0088] The garbage collection floating platform 100 is placed in the anaerobic pond 37 of the sewage treatment plant. The buoyancy of the water on the first float 4 and the second float 23 makes the entire garbage collection floating platform 100 float on the water surface of the anaerobic pond 37 of the sewage treatment plant.

[0089] The control and data processing module 21 controls the start of the sewage pump 22, drawing sewage from the anaerobic tank 37 of the sewage treatment plant through the pumping pipe 11 to the top of the filter screen 19. The water then falls onto the filter screen 19 for the first filtration, filtering out larger debris. Next, the water flows to the fine particles 30 on the side wall of the receiving platform shell 34, where it undergoes a second filtration, filtering out smaller debris. The water continues to flow down the side wall of the receiving platform shell 34 to the guide plate 31, where it flows through the gaps between adjacent baffles to the irregular needles 32, where the irregularly arranged needles perform a third filtration of debris. The water flows onto the drain platform 33 and through the permeable holes 38 to the bottom of the receiving platform shell 34, where it undergoes a fourth filtration. Finally, it is discharged back into the anaerobic tank 37 of the sewage treatment plant through the drain pipe 2.

[0090] The motor 8 is started by the sub-control mechanism and battery 9, which drives the impeller 7 to rotate, thereby propelling the water flow. The reaction force of the water flow acts on the waste cleaning floating platform 100, causing it to float within the anaerobic tank 37 of the wastewater treatment plant. The impellers 7, arranged in different directions, allow the waste cleaning floating platform 100 to float freely at 360°, ensuring effective cleaning of all locations within the anaerobic tank 37.

[0091] As the garbage cleaning floating platform 100 floats at different positions on the water surface and performs multiple filtrations, it can automatically clean up floating garbage, sludge flocculent matter, etc. in the anaerobic pond 37 of the sewage treatment plant, which can directly reduce the burden on downstream filtration and eliminate the need for manual cleaning with nets, saving time and effort.

[0092] Preferably, a pH sensor, which is used in the prior art for detecting the acidity and alkalinity of sewage, can be installed in the sewage pump 22. The pH value of the sewage can be detected while the sewage pump 22 is pumping sewage, and the data can be transmitted to the signal receiving equipment of the sewage treatment plant through the control and data processing module 21, so as to avoid the occurrence of medium and large water quality accidents.

[0093] A waste collection floating platform 100 of the corresponding size can be customized according to the dimensions of the anaerobic tank 37 of the sewage treatment plant to improve the cleaning speed. Alternatively, the entire waste collection floating platform 100 can be enlarged according to proportions and actual usage needs for similar applications or waste collection in rivers, lakes, and seas. Because the waste collection floating platform 100 contains electrical control equipment, attention should be paid to ensuring the waterproofing measures of the entire platform are adequate during manufacturing and use.

[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
