Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a cleaning machine and cleaning method for secondary sedimentation tanks. Background Technology

[0002] With the increasing emphasis on environmental protection by the country, secondary sedimentation tanks, as a simple and effective sewage treatment facility, are widely used in construction companies. However, there has been no economical and effective method for cleaning secondary sedimentation tanks. The effluent channel of the secondary sedimentation tank (especially the secondary sedimentation tank) is one of the key links to ensure that the final effluent water quality meets the standards.

[0003] However, under suitable light and humidity conditions, moss spores readily attach to, germinate, and proliferate on the inner wall of the effluent tank. The moss obtains energy and matter through photosynthesis, using the absorbed nutrients for cell division and reproduction, ultimately forming strip-shaped or flocculent floating colonies. These moss colonies not only create a visually unsightly and messy appearance in the effluent tank, giving visitors and inspectors a negative first impression and affecting the plant's image, but also bring a series of operational problems: irregular moss shedding may interfere with normal equipment operation (such as clogging pipes or entanglement of agitators) and affect the accuracy of online water quality monitoring instruments; more importantly, the floating and accumulated debris can easily clog the effluent weir, leading to uneven flow and distribution of water, disrupting the stable operation of the secondary sedimentation tank, and ultimately adversely affecting the overall effluent quality of the water treatment process.

[0004] Currently, the following methods are mainly used to clean algae from the effluent trough of secondary sedimentation tanks:

[0005] 1. Workers must periodically enter the narrow drainage trough to directly scrub away the algae using brushes, scouring pads, and other tools. This method is extremely labor-intensive, inefficient, and consumes a significant amount of manpower and time. More seriously, because the drainage trough usually extends into the pool, the operating space is extremely limited, posing significant safety hazards to workers, such as bumps, slips, and even falls into the water. Due to safety concerns, workers often find it difficult to thoroughly clean all corners.

[0006] 2. Workers tie brooms to long poles and then stand on the edge of the sink to operate the brooms. While this avoids the risks of going directly into the sink to some extent, it still requires workers to repeatedly adjust the broom position, making the operation clumsy and laborious, with low cleaning efficiency, and limited effectiveness in removing stubborn moss from the bottom and corners of the sink.

[0007] Therefore, there is an urgent need to develop a new type of secondary sedimentation tank cleaning equipment that can overcome the poor results of manual cleaning in the existing technology. Summary of the Invention

[0008] To address the aforementioned problems in the prior art, the present invention provides a cleaning machine for a secondary sedimentation tank; another objective of the present invention is to provide a cleaning method for a secondary sedimentation tank.

[0009] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0010] A cleaning machine for a secondary sedimentation tank includes a track, a moving platform, a cleaning device for cleaning the walls of the secondary sedimentation tank, a drive component, and a bending and extending component; the track is arranged along the walls of the secondary sedimentation tank, and the moving platform is arranged above the track by the drive component and can move along the length of the track;

[0011] The bending and stretching component is connected between the moving platform and the cleaning device, so that the cleaning device can be movably installed under the moving platform and can bend and stretch to contact the wall of the secondary sedimentation tank.

[0012] Furthermore, the bending and extending component includes a bending and extending motor, a rotating component, and a telescopic component; the bending and extending motor drives the rotating component, and both the rotating component and the telescopic component are movably connected to the cleaning device, enabling the cleaning device to bend and extend to contact the wall of the secondary sedimentation tank.

[0013] Preferably, the rotating component is a connecting rod, one end of which is connected to the bending and extending motor, and the other end is connected to the cleaning device; the telescopic component is a piston cylinder, one end of which is located at the bottom of the moving platform, and the other end is connected to the cleaning device.

[0014] Furthermore, the cleaning device includes a cleaning motor, a cleaning brush, and an abutting component; the rotating component and the telescopic component are movably connected to the cleaning device, and the cleaning motor drives the cleaning brush; the abutting component is disposed above the cleaning brush to limit the displacement range of the cleaning brush during its movement.

[0015] Furthermore, the sweeping brush includes a roller brush, and the sweeping motor is connected to the roller brush via a drive shaft.

[0016] Preferably, the cleaning device further includes a connecting frame, a cleaning motor is provided inside the connecting frame, and a roller brush is vertically provided below the connecting frame. The rotating part and the telescopic part are both movably connected to the connecting frame, so that the roller brush can bend and extend to contact the wall of the secondary sedimentation tank.

[0017] Furthermore, the abutting component includes a limiting block and a limiting roller, the limiting block being disposed above the roller brush and the limiting roller being disposed at the end of the limiting block.

[0018] Furthermore, the sweeping motor is connected to the sweeping brush via a drive shaft.

[0019] Furthermore, the driving component includes a driving wheel, a vertical positioning wheel, and a lateral positioning wheel for providing driving force; the driving wheel, the vertical positioning wheel, and the lateral positioning wheel are all located below the moving platform and abut against the track.

[0020] Preferably, the vertical positioning wheel abuts against the track to restrict the movement of the mobile platform in the vertical direction; the lateral positioning wheel abuts against the track to restrict the movement of the mobile platform in the lateral direction (perpendicular to the length of the track).

[0021] Furthermore, the mobile platform is provided with a storage cavity, and the storage cavity is also provided with a storage battery; the mobile platform is also provided with a camera for monitoring; the mobile platform is also provided with a solar panel, and the solar panel is electrically connected to the storage battery.

[0022] Preferably, the storage cavity is also equipped with a bending motor.

[0023] Furthermore, the track includes a first track and a second track, the first track being disposed on the wall of the secondary sedimentation tank and the second track being disposed on the outside of the filter screen; the driving component is configured as two sets of equal driving structures, with the first track and the second track maintaining an equidistant distance.

[0024] The cleaning machine is equipped with two sets of drive components, which respectively abut against the first track and the second track.

[0025] Furthermore, a cleaning brush is also provided below the mobile platform, and the cleaning brush is connected to a motor inside the mobile platform.

[0026] A cleaning method for a secondary sedimentation tank, the cleaning method for the secondary sedimentation tank comprising the following steps:

[0027] S1: Install the mobile platform on the preset track on the wall of the secondary sedimentation tank, so that the drive wheel, vertical positioning wheel and lateral positioning wheel of the drive component abut against the first track and the second track respectively, to ensure that the mobile platform is stably set above the track;

[0028] S2: Start the drive unit to move the moving table along the length of the track to the preset starting cleaning position;

[0029] S3: The extension motor works in sync with the telescopic component to rotate the drive screwing component, thereby dynamically adjusting the angle of the cleaning brush so that it fits tightly against the irregular curved surface of the secondary sedimentation tank wall and precisely controls the contact pressure between the cleaning brush and the tank wall.

[0030] S4: Start the sweeping motor to drive the sweeping brush to rotate at high speed and clean the pollutants attached to the pool wall;

[0031] S5: The drive component pushes the moving platform to move at a constant speed along the track, while the bending and stretching component dynamically adjusts the contact state of the cleaning brush to achieve continuous and dead-angle-free longitudinal cleaning coverage of the secondary sedimentation tank wall.

[0032] S6: After cleaning is completed, the drive unit moves the moving platform to a safe position; the extension and retraction parts retract the cleaning brush to the initial state; then the cleaning motor and drive unit are turned off to end the cleaning operation.

[0033] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0034] ① This equipment connects the moving platform and the cleaning equipment (especially the cleaning brush, which is directly and dynamically connected) through a bending and extending component (including a bending and extending motor, a rotating connection component, and a telescopic component), enabling the cleaning brush to actively perform multi-degree-of-freedom bending and extending movements. This effectively adapts to the curved, uneven, and complex structure of the secondary sedimentation tank wall, ensuring that the cleaning brush always maintains a tight fit against the tank wall surface. Compared to existing rigid connection or simple suspension cleaning devices, this solution significantly improves cleaning coverage and cleaning effect, and solves the problem of cleaning dead spots caused by poor fit.

[0035] ② The drive unit of this equipment adopts a three-wheel coordinated structure of drive wheels, vertical positioning wheels, and lateral positioning wheels. The positioning wheels abut and constrain the track, while the drive wheels provide stable driving force. The vertical positioning wheels effectively constrain the movement of the moving platform in the vertical direction, preventing the equipment from derailing or jumping. The lateral positioning wheels constrain the movement of the moving platform in the direction perpendicular to the track, preventing the equipment from lateral swaying or deviating. This ensures that the cleaning machine has extremely high stability and positioning accuracy when running along the track on the wall of the secondary sedimentation tank. Even in harsh working conditions such as wetness, slipperiness, or the presence of foreign objects, the accuracy of the cleaning path can be guaranteed, avoiding the impact on cleaning effect or collisions due to inaccurate positioning.

[0036] ③ The mobile platform integrates a battery to power the entire system, eliminating the need for cables and expanding the working range. A solar panel is added to the mobile platform and electrically connected to the battery, allowing for continuous charging using ambient light. This design significantly extends the equipment's single-operation time and endurance, reduces the frequency of manual battery replacement, and is particularly suitable for long-term unattended operation of secondary sedimentation tanks in well-lit areas, improving energy efficiency and operational autonomy.

[0037] ④ The camera is integrated into the mobile platform, enabling real-time monitoring of the cleaning process and working environment. This facilitates remote observation of equipment status, cleaning effect, and potential faults, improving the manageability and safety of the equipment. Attached Figure Description

[0055] Example 1

[0056] like Figure 1-11 As shown, this embodiment discloses a cleaning machine for a secondary sedimentation tank, including a track 1, a moving platform 2, a cleaning device 3 for cleaning the walls of the secondary sedimentation tank, a driving component 4, and a bending and extending component; the track 1 is arranged along the walls of the secondary sedimentation tank, and the moving platform 2 is arranged above the track 1 through the driving component 4 and can move along the length of the track 1.

[0057] The bending and stretching component is connected between the moving platform 2 and the cleaning device 3, so that the cleaning device 3 can be movably installed under the moving platform 2 and can bend and stretch to contact the wall of the secondary sedimentation tank.

[0058] The bending and extending component includes a bending and extending motor 5, a rotating component 6, and a telescopic component 7; the bending and extending motor 5 drives the rotating component 6, and both the rotating component 6 and the telescopic component 7 are movably connected to the cleaning device 3, so that the cleaning device 3 can bend and extend to contact the wall of the secondary sedimentation tank.

[0059] The cleaning device 3 includes a cleaning motor 301, a cleaning brush 302, and an abutment component 303; a rotating component 6 and a telescopic component 7 are movably connected to the cleaning device 3, and the cleaning motor 301 drives the cleaning brush 302; the abutment component 303 is disposed above the cleaning brush 302 and is used to limit the displacement range of the cleaning brush 302 during the movement.

[0060] During initial positioning, the moving platform 2 of the cleaning machine is installed on the preset track 1 on the wall of the secondary sedimentation tank; after starting, the drive component 4 drives the moving platform 2 to move along the length of track 1 to the starting cleaning position; the bending and stretching component (including bending and stretching motor 5, rotating component 6, and telescopic component 7) drives the cleaning equipment 3 to move to a position close to the tank wall.

[0061] When the secondary sedimentation tank 11 needs to be cleaned, the extension motor 5 drives the rotating component 6 to dynamically adjust the position of the cleaning brush 302 so that it fits tightly against the irregular curved surface of the secondary sedimentation tank 11.

[0062] The telescopic component 7 extends and retracts synchronously, precisely controlling the contact pressure between the cleaning brush 302 and the pool wall, avoiding insufficient pressure leading to incomplete cleaning or excessive pressure damaging the pool wall; while the abutting component 303 restricts the displacement of the cleaning brush 302 during its bending and stretching movements, preventing excessive damage to the cleaning brush 302.

[0063] The sweeping motor 301 drives the sweeping brush 302 to rotate at high speed, powerfully cleaning the sludge, biofilm and other pollutants attached to the pool wall;

[0064] The drive component 4 pushes the mobile platform 2 to move along the track 1, achieving continuous, seamless longitudinal cleaning coverage.

[0065] Specifically, the rotation angle adjustment of the rotating component 6 in this solution, combined with the extension and retraction control of the telescopic component 7, enables the cleaning brush 302 to actively adapt to the curvature changes of the secondary sedimentation tank wall (such as arc corners, weld protrusions, etc.), solving the "partial suspension" problem of traditional rigid brushes and improving the cleaning coverage.

[0066] Specifically, the contact pressure between the cleaning brush 302 and the pool wall can be dynamically adjusted according to the adhesion of sludge on the pool wall, avoiding "missed cleaning" or "scratching of the pool wall" caused by uneven pressure, thus extending the service life of the pool.

[0067] As one embodiment, the sweeping brush 302 includes a roller brush, and the sweeping motor 301 drives the roller brush via a drive shaft.

[0068] The abutting component 303 includes a limiting block and a limiting roller. The limiting block is located above the roller brush, and the limiting roller is located at the end of the limiting block.

[0069] The cleaning device 3 also includes a connecting frame, in which a cleaning motor 301 is installed. A roller brush is vertically installed below the connecting frame. The screw-on component 6 and the telescopic component 7 are both movably connected to the connecting frame, so that the roller brush can bend and extend to contact the wall of the secondary sedimentation tank.

[0070] Specifically, track 1 is made of stainless steel and is laid in a ring along the top of the secondary sedimentation tank; the moving platform 2 has a storage cavity inside, with a built-in battery 8 and a bending motor 5; a camera 9 is installed on the top of the moving platform 2.

[0071] The sweeping motor 301 uses a variable frequency motor to drive the roller brush at a speed of 0-200 rpm; the roller brush has a stainless steel shaft core and is covered with nylon bristles.

[0072] During operation, the moving platform 2 moves along the track 1 to the starting point of the pool wall, and the telescopic component 7 extends to make the roller brush bend and stretch.

[0073] The extension motor 5 drives the rotating component 6 to rotate, adjusting the axis of the roller brush to be parallel to the curved surface of the pool wall; then the telescopic component 7 advances synchronously, so that the bristles contact the pool wall with appropriate pressure, and then the cleaning motor 301 starts the roller brush to rotate at 120 rpm to scrape off the sludge.

[0074] The drive component 4 pushes the moving platform 2 to move and locks the track 1 to prevent deviation.

[0075] In this embodiment, dynamic fitting is achieved by connecting the roller brush with the telescopic component, and multiple limiting rollers are provided at the end of the limiting block.

[0076] When the extended roller brush is in operation, the limiting roller located above the roller brush first contacts the pool wall, guiding the roller brush to precisely conform to the pool wall; when the cleaning machine moves along track 1, the limiting roller rolls along the pool wall, which can effectively adapt to the irregular pool wall contour, allowing the roller brush below to clean the pool wall contour, ensuring a thorough cleaning without any dead corners.

[0077] As one embodiment, track 1 includes a first track 101 and a second track 102. The first track 101 is disposed on the wall of the secondary sedimentation tank, and the second track 102 is disposed outside the filter screen. The first track 101 and the second track 102 are equidistant from each other.

[0078] The cleaning machine is equipped with two sets of drive components 4, which respectively abut against the first track 101 and the second track 102;

[0079] A cleaning brush 302 is also provided below the mobile platform 2, and the cleaning brush 302 is connected to the motor inside the mobile platform 2.

[0080] The secondary sedimentation tank is also equipped with a filter screen 12, which separates the secondary sedimentation tank into a clean area 13 and a water collection area 14. The two sets of drive components 4 below the cleaning machine of this equipment are respectively installed on the first track 101 and the second track 102. By running the two sets of drive components 4 on the first track 101 and the second track 102, the cleaning machine of this equipment can clean and remove scale from the two walls of the clean area (the walls of the secondary sedimentation tank and the walls of the filter screen).

[0081] Specifically, the sweeping machine is equipped with an independent sweeping brush 302 at the bottom, which can clean the surface of the filter screen 12 while the sweeping machine is running.

[0082] The second track 102 is positioned above the filter screen 12. The cleaning brush 302 contacts the screen wall of the filter screen 12. The cleaning brush 302 is driven by a motor to rotate and clean the sediment on the screen wall.

[0083] Specifically, the cleaning brush 302 below the cleaning machine of this device is set to fit the filter screen 12. When the drive wheel 401 runs on the second track 102, the motor is turned on to make the cleaning brush 302 rotate, so as to remove the sediment on the screen wall of the filter screen 12.

[0084] In addition, this equipment should also have safety designs such as anti-slip, shockproof and waterproof to ensure safe operation during the cleaning process.

[0085] Specifically, the wheels of the drive component 4 are knurled, and the motor operates at constant torque to effectively achieve anti-slip effect. The guide wheels and guide devices of the drive component 4 can "lock" the robot in the track 1 and achieve shock absorption effect. The sealant applied to the gaps of the camera and other parts can achieve waterproof effect.

[0086] As one embodiment, the sweeping motor 301 is connected to the sweeping brush 302 via a drive shaft.

[0087] Specifically, the sweeping motor 301 adopts an IP68 protection-rated variable frequency motor. The torque of the sweeping motor 301 is transmitted to the sweeping brush 302 through the drive shaft, ensuring high torque transmission without loss and avoiding uneven wear caused by stress torsion of the brush body.

[0088] As one embodiment, the driving component 4 includes a driving wheel 401, a vertical positioning wheel 402, and a lateral positioning wheel 403 for providing driving force; the driving wheel 401, the vertical positioning wheel 402, and the lateral positioning wheel 403 are all disposed below the moving platform 2 and abut against the track 1.

[0089] Specifically, track 1 is made of I-beams and laid along the top of the pool wall; drive wheel 401 has a polyurethane tread; vertical positioning wheel 402 is a double-flange nylon wheel, clamping the top of track 1 and the edge of the web; lateral positioning wheel 403 is a rubber wheel that abuts against the two sides of the web of track 1.

[0090] During operation, the drive wheel 401 propels the moving platform 2; the vertical positioning wheel 402 clamps the top of the track 1 and the edge of the web plate to eliminate vertical jump; the lateral positioning wheel 403 abuts against the web plate of the track 1 to suppress crosswind disturbance.

[0091] When passing through a curve, the vertical positioning wheel 402 and the lateral positioning wheel 403 abut against the track 1, clamping and counteracting the tendency to deviate caused by centrifugal force; during emergency braking, the vertical wheel 402 locks the track to prevent derailment, and the lateral wheel 403 abuts against the web of the track 1 to prevent overturning.

[0092] This embodiment effectively solves the safety hazards of deviation, derailment, and slippage in large secondary sedimentation tank track sweepers by using the constraints of vertical positioning wheel 402 and lateral positioning wheel 403.

[0093] As one embodiment, the mobile station 2 is provided with a storage cavity, and the storage cavity is also provided with a battery 8.

[0094] Specifically, the internal storage compartment of the mobile station 2 adopts a compartmentalized shockproof design and has multiple sets of lithium iron phosphate batteries 8 built in, supporting wide temperature operation from -20℃ to 60℃; a dual-spectrum gimbal camera 9 is embedded on the top of the mobile station 2.

[0095] During operation, camera 9 captures images of the pool wall every 10 seconds and uses AI algorithms to identify pools wider than 0.1m. 2 Residual sludge is automatically reworked, and the brush pressure is adjusted in real time, improving the cleaning compliance rate.

[0096] When camera 9 detects a foreign object entangled in the brush body, it immediately stops and sends an alarm, thus ending the monitoring process.

[0097] As one embodiment, the mobile station 2 is also equipped with a solar panel 10, which is electrically connected to the battery 8.

[0098] Mobile station 2 is installed with its top surface flush against the surface at a height of 1.8m. 2 The monocrystalline silicon solar panel 10 is intelligently connected to the lithium iron phosphate battery 8 in the storage cavity, and together with the dual-spectrum camera 9, it forms an integrated energy-monitoring system.

[0099] When the solar panel 10 starts automatically in the morning, it charges the battery 8. On cloudy days, it automatically switches to the battery 8 to ensure continuous operation, and the camera 9 performs low-power inspection. Ultimately, it achieves all-weather operation capability with little or no external power connection. Combined with the sludge recognition and fault warning function of the camera 9, it can maintain a multi-day battery life, reduce fault response delay, and improve work efficiency.

[0100] Example 2

[0101] like Figure 12As shown, the difference between the secondary sedimentation tank in this embodiment and that in embodiment 1 is that the cleaning machine of this device has three sets of flexible components connected to different cleaning devices. Two sets of flexible components are connected to the cleaning devices to clean the walls of the secondary sedimentation tank 11, and one set of flexible components is connected to the cleaning devices to clean the walls of the filter screen 12.

[0102] When the filter screen 12 needs to be cleaned, the extension motor 5 drives the rotating part 6 to dynamically adjust the position of the cleaning brush 302 so that it fits tightly against the irregular curved surface of the filter screen 12.

[0103] The telescopic component 7 extends and retracts synchronously, precisely controlling the contact pressure between the sweeping brush 302 and the filter screen 12, avoiding insufficient pressure leading to incomplete cleaning or excessive pressure damaging the screen wall; while the abutting component 303 restricts the displacement of the sweeping brush 302 during its bending and stretching movement, preventing excessive damage to the sweeping brush 302.

[0104] The cleaning motor 301 drives the cleaning brush 302 to rotate at high speed, which powerfully cleans the sludge, biofilm and other pollutants attached to the pool wall.

[0105] Example 3

[0106] like Figure 1-12 As shown, this embodiment discloses a cleaning method for a secondary sedimentation tank, which includes the following steps:

[0107] S1: Install the mobile platform 2 on the preset track 1 on the wall of the secondary sedimentation tank, so that the drive wheel 401, vertical positioning wheel 402 and lateral positioning wheel 403 of the drive component 4 abut against the first track 101 and the second track 102 of the track 1 respectively, to ensure that the mobile platform 2 is stably set above the track.

[0108] S2: Start the drive unit 4 and drive the moving table 2 to move along the length of the track 1 to the preset starting cleaning position;

[0109] S3: The extension motor 5 and the telescopic component 7 extend and retract synchronously, causing the drive screwing component 6 to rotate, thereby dynamically adjusting the angle of the sweeping brush 302 so that it closely fits the irregular curved surface of the secondary sedimentation tank wall and precisely controls the contact pressure between the sweeping brush 302 and the tank wall.

[0110] S4: Start the sweeping motor 301 to drive the sweeping brush 302 to rotate at high speed and clean the pollutants attached to the pool wall;

[0111] S5: The driving component 4 pushes the moving platform 2 to move at a constant speed along the track 1, while the bending and stretching component dynamically adjusts the contact state of the cleaning brush 302 to achieve continuous and dead-angle-free longitudinal cleaning coverage of the secondary sedimentation tank wall.

[0112] S6: After cleaning is completed, the drive unit 4 moves the moving platform 2 to a safe position; the extension and retraction parts retract the cleaning brush 302 to the initial state; then the cleaning motor 301 and the drive unit 4 are turned off to end the cleaning operation.

[0113] When the equipment is working on the straight section of track 1, the drive component 4 controls the two sets of drive wheels 401 to run at the same speed, pushing the moving platform 2 to move at a constant speed along the track.

[0114] When there is a curve in the track, the drive wheel of the first track 101 (closer to the pool wall) speeds up, while the drive wheel of the second track 102 (inside the pool) slows down, achieving smooth steering through the speed difference.

[0115] As the curvature of the pool wall changes more intensely when turning, the rotating component 6 increases the adjustment frequency through the bending and stretching motor 5, and the telescopic component 7 can also compensate for the pressure fluctuations caused by centrifugal force in real time, preventing the sweeping brush 302 from swinging off in a large range, thereby preventing damage to the sweeping brush 302.

[0116] Specifically, this invention can also be equipped with an AI monitoring system for the outlet weir and a machine vision recognition algorithm system.

[0117] First, import the baseline image of the effluent weir of the secondary sedimentation tank in a clean state into the AI ​​monitoring system. When working, the camera (9) captures the image of the effluent weir of the tank wall in real time.

[0118] The AI ​​system uses machine vision algorithms to compare baseline images, identify target areas where sludge / biofilm adheres, and generate cleaning coordinates.

[0119] Then, the drive component 4 is controlled to move to the target area, the extension motor 5 drives the rotating component 6 to adjust the angle of the cleaning brush 302, and the telescopic component 7 controls the contact pressure; the cleaning motor 301 starts, driving the cleaning brush 302 to rotate at high speed to clean the target area.

[0120] After cleaning, camera 9 re-scans the cleaned area, and the AI ​​system compares the cleanliness with the baseline image; once the verification is successful, the mobile station 2 returns to a safe position, and the cleaning brush 302 retracts and resets.

[0121] The deep integration of machine vision and adaptive mechanical control ensures the cleanliness of the outlet weir.

[0122] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
