Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and more specifically, to a pool scrubber, system, and cleaning method for a water tank. Background Technology

[0002] Because suspended solids, organic debris, and microbial activity in the pool water cause nutrients (such as nitrogen and phosphorus) to deposit on the surface of the pool walls, the water flow near the pool walls is usually slower than in the center of the pool. This makes it easier for algal spores and early growth bodies to attach and grow stably, and they are not easily washed away by the water flow. Over time, a microbial film may form on the pool walls. This biofilm provides additional attachment points and a nutritional basis for the algae, accelerating their reproduction.

[0003] Areas prone to algae growth include secondary sedimentation tanks, storage tanks, and swimming pools. Specifically, secondary sedimentation tanks are an important component of activated sludge systems. Their main function is to separate sludge, clarify the mixed liquor, concentrate it, and return the activated sludge. Their performance directly affects the effluent quality and the concentration of returned sludge from the activated sludge system. Large and medium-sized wastewater treatment plants mostly use circular radial flow sedimentation tanks with mechanical sludge suction; medium-sized plants may use multi-hopper horizontal flow sedimentation tanks; and small plants often use vertical flow sedimentation tanks.

[0004] Because the walls of the secondary sedimentation tank will produce a large amount of algae, grow moss, and breed mosquitoes and other insects to lay eggs, which may produce algal toxins, red worms and other water quality risks. At the same time, a lot of dirt will also be attached. The sludge scraper cannot remove the algae on the walls of the tank, resulting in a large accumulation of algae on the walls of the secondary sedimentation tank that is difficult to remove.

[0005] Normally, the above situation requires regular cleaning by workers. However, manual cleaning involves working at heights, posing certain safety risks. Furthermore, manual scraping of the pool walls can easily miss areas. The cleaning work is extensive, difficult, and physically demanding, resulting in low efficiency, especially in inclement or humid weather. Additionally, the cleaning process requires stopping water production and draining the sedimentation tank. This approach is not economical, has a long cleaning cycle, and in the later stages of the cleaning cycle, the sedimentation tank becomes very dirty, significantly degrading the water quality.

[0006] For example, a secondary sedimentation tank cleaning device (CN213965303U) includes a secondary sedimentation tank body, a sludge scraper arm, and a drive mechanism. An overflow weir is provided in the secondary sedimentation tank body, and an annular slag baffle is provided on the inner side of the overflow weir via a support rod. A first cleaning mechanism and a second cleaning mechanism are provided on the sludge scraper arm. The present invention uses the sludge scraper of the first cleaning mechanism to scrape off the scum, moss, and algae on the slag baffle, and uses the second cleaning mechanism to perform high-pressure spray washing of the inner wall of the secondary sedimentation tank body, the inner and outer walls of the overflow weir, and the inner and outer walls of the slag baffle to remove moss and algae, thereby reducing manual labor and improving safety and work efficiency.

[0007] However, this patent uses high-pressure water spray for cleaning. During long-term use of the secondary sedimentation tank, algae and other debris easily adhere to the inner wall of its overflow weir. Since the secondary sedimentation tank is large, manual cleaning is quite troublesome. Also, as shown in the patent, it uses high-pressure water spray for cleaning. However, when using high-pressure water spray, if the nozzle's outlet diameter is small, the water impact force will be stronger. This will result in a smaller area hitting the inner wall of the overflow weir, thus reducing the cleaning area when cleaning algae and other adherent materials. If the nozzle's outlet diameter is large, although the spray area increases, the water impact force decreases, resulting in a poor cleaning effect. This reduces the cleaning area when cleaning algae and other adherent materials, thus affecting the cleaning effect. Summary of the Invention

[0042] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0043] ① By placing the fixed guide components and drive components at the bottom of the support frame and abutting against the pool wall, the stability of the pool brush during operation can be effectively enhanced, ensuring the equipment is stable during operation, reducing vibration, and protecting the pool wall from damage.

[0044] ② The push spring mechanism uses the elastic potential energy of the spring inside the spring to drive the spring push rod to extend and retract, thereby pushing the push rod bracket and further dynamically adjusting the pressure of the push spring limit wheel on the pool wall. This precisely controls the contact force with the pool wall, ensuring smooth movement along the pool wall and maintaining good fit and cleaning effect.

[0045] ③ By vertically connecting the brush connecting cylinder to the end of the brush transmission frame, it is possible to clean the bottom wall of the pool of floating algae and other adhering substances.

[0046] The walls of a water tank are usually vertical or near-vertical planes. Vertically installed brushes ensure that the bristles are completely in contact with the bottom of the tank. A drive motor drives the brush rod to rotate and sweep the bristles at the bottom, effectively covering and thoroughly cleaning the surface of the tank walls.

[0047] ④ By connecting the brush connecting cylinder parallel to the end of the brush transmission frame, it is possible to clean the side walls of the pool of floating algae and other adhering substances.

[0048] The bottom wall of a pool is usually a vertical or near-vertical plane. Parallel-mounted brushes ensure that the bristles are completely in contact with the side wall of the pool. The brush rod is driven by a drive motor to rotate and sweep the side bristles, effectively covering and thoroughly cleaning the bottom wall surface.

[0049] ⑤ The control center analyzes the video data identified by the camera, calculates the location of algae based on the image detected by the SUSAN operator and the RGB color difference formula, and then selects and adjusts the cleaning method.

[0070] Example 1

[0071] like Figure 1-9As shown, this embodiment discloses a pool scrubber for a water tank, including: a support frame 1, a drive device 2, a cleaning device 3, and a control center; the drive device 2 is installed on the support frame 1, and when in use, the drive device 2 is in contact with the pool wall to drive the support frame 1 to move along the pool wall; the cleaning device 3 is installed on the support frame 1 to clean the pool wall, and the control center is electrically connected to the drive device 2 and the cleaning device 3.

[0072] The driving device 2 includes a fixed guide component 206, a push spring limiting component, and a driving component. The fixed guide component 206 is located at the bottom of the support frame 1 and abuts against the pool wall when in use. The driving component is located at the bottom of the support frame 1 and abuts against the pool wall when in use. The push spring limiting component includes a push spring mechanism 201, a push spring limiting rod 202, and a push spring limiting wheel 203. The push spring mechanism 201 is located on the support frame 1. The bottom of the push spring limiting rod 202 is connected to the push spring limiting wheel 203. The push spring mechanism 201 is movably connected to the top of the push spring limiting rod 202 to drive the push spring limiting wheel 203 to abut against the pool wall.

[0073] During operation, the fixed guide component 206, the push spring limiting component and the drive component are respectively set at the bottom of the support frame 1 and abut against the wall of the secondary sedimentation tank 8. Then the drive component is turned on, so that the cleaning device 3 moves along the wall of the secondary sedimentation tank 8 and cleans. This can effectively enhance the stability of the cleaning operation of the scrubber, ensure that the equipment is stable during operation, reduce vibration, and protect the tank wall from damage.

[0074] When necessary, camera 6 can also be used to identify the location of algae on the pool wall, thereby communicating the image data to the control center. The control center makes intelligent identification based on the image data and issues instructions to control the drive device 2 and the cleaning device 3 respectively, effectively achieving effective coverage and thorough cleaning of algae on the bottom wall surface.

[0075] Specifically, a hinge buckle 7 is provided between the connecting frame 5 and the support frame 1. By using the hinge buckle 7, the solar panel 4 on the top of the support frame 1 and the connecting frame 5 can be lifted up. When it is necessary to maintain the solar panel or clean the surface, the staff can operate quickly and without obstacles without complicated disassembly, which greatly saves maintenance time and costs. In the event of extreme weather conditions, such as strong winds, heavy rain, or in the event of emergency evacuation, the solar panel can be quickly retracted to reduce the risk of damage and protect the equipment.

[0076] In one specific implementation, the driving component includes a drive motor 204 and a drive wheel 205; the drive motor 204 is mounted on the support frame 1 and synchronously drives the drive wheel 205 connected to the bottom of the support frame 1.

[0077] The spring push mechanism 201 includes a lug seat 2011, a spring push rod 2012, and a push rod bracket 2013; the push rod bracket 2013 is mounted on the support frame 1, the spring push rod 2012 is connected to the push rod bracket 2013, and the telescopic end of the spring push rod 2012 is movably connected to the top of the spring limit rod 202, and the lug seat 2011 is movably connected to the spring limit rod 202.

[0078] Specifically, the support frame 1 is provided with a slot, and the edge of the slot is provided with a lifting lug 2011. The lifting lug 2011 is movably connected to the push spring limiting rod 202. During operation, the push spring mechanism 201 drives the spring push rod 2012 to extend and retract through the elastic potential energy of the spring inside the spring push rod 2012, thereby pushing the push rod bracket 2013, further dynamically adjusting the pressure of the push spring limiting wheel 203 on the pool wall, accurately controlling the contact force with the pool wall, ensuring that it can move smoothly along the pool wall, thereby maintaining good fit and cleaning effect.

[0079] Specifically, the fixed guide component 206 includes a fixed guide wheel and a fixed guide rod 206. The fixed guide rod 206 is mounted on the support frame 1 and is movably connected to the fixed guide wheel at the bottom. This can effectively prevent the pool brush from deviating from the predetermined trajectory and maintain stable movement even on complex or curved pool wall surfaces, effectively improving the accuracy of cleaning operations.

[0080] As a specific implementation, the drive wheel 205 of the drive component is installed at the bottom of the support frame 1. An auxiliary wheel is also provided at the bottom of the support frame 1. The drive component moves in a "front-drive" or "rear-drive" manner to ensure that the scrubber can improve its steering flexibility through the auxiliary wheel, thereby maintaining good fit and cleaning effect.

[0081] Specifically, the drive components are provided in several sets, and multiple sets of drive wheels 205 are arranged and installed at the bottom of the support frame 1. The drive components move in an "all-wheel drive" manner, which can provide excellent grip, avoid slipping, maintain stable forward momentum, and ensure that the pool brush can move smoothly along the pool wall, thereby maintaining good fit and cleaning effect.

[0082] In one specific implementation, a fixed guide component 206 and a push spring limiting component form a row of limiting devices. The bottom of the support frame 1 is provided with multiple rows of driving components to ensure that the driving components of the pool brush move stably along the pool wall trajectory and avoid deviation or shaking.

[0083] Alternatively, a fixed guide component 206 and multiple push spring limiting components form a row of limiting devices, and the bottom of the support frame 1 is provided with multiple rows of driving components, which can effectively simplify the structure, reduce the assembly complexity, and at the same time ensure that each key point on the motion path has precise position control.

[0084] In one specific implementation, the cleaning device 3 includes a brush drive frame 301, a brush connecting cylinder 302, a brush rod 303, brush bristles 304, and a brush pool motor 305; the brush drive frame 301 is connected to the brush connecting cylinder 302, the brush connecting cylinder 302 is provided with a slot, the brush rod 303 is installed on the brush connecting cylinder 302 and can slide along the length direction of the brush connecting cylinder 302, and the brush bristles 304 are installed on the brush rod 303 and can extend out along the slot of the brush connecting cylinder 302;

[0085] The cleaning device 3 also includes a ball 306 and a ball spring 307. The brush connecting cylinder 302 is also provided with an abutment hole, and the brush rod 303 is provided with a radial groove. The ball 306 is set in the radial groove by the ball spring 307. The ball spring 307 uses its elasticity to hold the ball 306 into the connection between the radial groove and the abutment hole.

[0086] The brush pool motor 305 is mounted on the support frame 1. The brush transmission frame 301 is disposed inside the support frame 1 and its two ends pass through the side wall of the support frame 1 and extend to the outside. One end of the brush transmission frame 301 is driven and connected to the output shaft of the brush pool motor 305, and the other end is shaft-connected to the brush connecting cylinder 302.

[0087] When assembling the algae-cleaning brush, the brush rod 303 is slid along the inside of the brush connecting cylinder 302 and adjusted to the desired position, so that the bristles 304 extend along the groove of the brush connecting cylinder 302. Then, the brush rod 303 is fixed to the inside of the brush connecting cylinder 302 by the ball 306 and the ball spring 307, which realizes the flexible adjustment of the length of the bristles 304 and the stable locking of the brush rod 303. This not only improves cleaning efficiency, but also facilitates the user's operation and maintenance.

[0088] Specifically, the ball 306 is set in the radial groove on the brush rod 303 via the ball spring 307. The ball spring 307 provides the necessary elastic force to engage the ball 306 at the connection between the radial groove and the abutment hole. This not only fixes the position of the brush rod 303 but also maintains a certain degree of adjustability. When the position of the brush rod 303 needs to be adjusted, an appropriate force is applied to press the ball 306 into the abutment hole, causing the ball spring 307 to contract and provide space for the ball 306 to retract, thus overcoming the elastic force. After adjustment, the ball 306 automatically returns to its locked position, enhancing the stability and durability of the entire device.

[0089] Specifically, the bristle material 304 includes steel wire and nylon. The steel wire bristles 304 and nylon bristles 304 are spaced apart and installed on the outside of the brush connecting cylinder 302. The steel wire bristles 304 are suitable for cleaning hard surfaces, while the nylon bristles 304 are suitable for soft or uneven surfaces. The dual-material spaced design can save costs while ensuring cleaning effect by reasonably allocating the use of different materials.

[0090] Specifically, when the brush is working, especially when it is rotating at high speed, it will be subjected to a large centrifugal force, which may cause the brush rod 303 to come off the brush connecting cylinder 302. By setting an internal thread at the end of the brush connecting cylinder 302 and using a plug to connect the threaded end to block it, it can be ensured that the brush rod 303 is firmly locked inside the brush connecting cylinder 302, which can effectively enhance the stability of the entire brush assembly and prevent it from falling off due to vibration or high-speed rotation during operation.

[0091] In one specific implementation, a solar panel 4 is provided on the top of the support frame 1, and the solar panel 4 is movably mounted on the top of the support frame 1 via a connecting frame 5;

[0092] The control center is electrically connected to the solar panel 4 and the battery. The solar panel 4 charges the battery through the control center, and the battery supplies power to the drive unit 2 and the cleaning unit 3 through the inverter.

[0093] Specifically, the electricity generated by the solar panel 4 is boosted by the control center to charge the battery, which in turn serves as an energy storage unit, supplying power to the drive unit 2 and the cleaning unit 3 during periods without sunlight or peak electricity demand. The inverter converts the direct current from the battery into alternating current to ensure the normal operation of the equipment. This configuration guarantees the continuity and stability of the power supply.

[0094] Example 2

[0095] like Figure 1-9 As shown, this embodiment discloses a pool scrubber for a water tank, including: a support frame 1, a drive device 2, a cleaning device 3, and a control center; the drive device 2 is installed on the support frame 1, and when in use, the drive device 2 is in contact with the pool wall to drive the support frame 1 to move along the pool wall; the cleaning device 3 is installed on the support frame 1 to clean the pool wall, and the control center is electrically connected to the drive device 2 and the cleaning device 3.

[0096] The driving device 2 includes a fixed guide component 206, a push spring limiting component, and a driving component. The fixed guide component 206 is located at the bottom of the support frame 1 and abuts against the pool wall when in use. The driving component is located at the bottom of the support frame 1 and abuts against the pool wall when in use. The push spring limiting component includes a push spring mechanism 201, a push spring limiting rod 202, and a push spring limiting wheel 203. The push spring mechanism 201 is located on the support frame 1. The bottom of the push spring limiting rod 202 is connected to the push spring limiting wheel 203. The push spring mechanism 201 is movably connected to the top of the push spring limiting rod 202 to drive the push spring limiting wheel 203 to abut against the pool wall.

[0097] In one specific implementation, the brush connecting cylinder 302 is vertically connected to the end of the brush transmission frame 301, with the groove of the brush connecting cylinder 302 facing downwards. The brush rod 303 is installed on the brush connecting cylinder 302, and the bristles 304 are installed on the brush rod 303 and can extend downwards along the groove at the bottom of the brush connecting cylinder 302.

[0098] Specifically, the edge of the brush connecting cylinder 302 is parallel to the end edge of the brush transmission frame 301, and both ends of the brush connecting cylinder 302 are threaded with plugs to prevent the brush rod 303 from being thrown out and falling.

[0099] Since the bottom wall of the pool is usually a vertical or near-vertical plane, the vertically installed brush connecting cylinder 302 can ensure that the brush bristles 304 are completely in contact with the bottom of the pool. The brush motor 305 drives the brush rod 303 to rotate and sweep the brush bristles 304 at the bottom, effectively achieving effective coverage and thorough cleaning of the bottom wall surface of the pool.

[0100] Specifically, the bristles 304 are usually made of materials with a certain degree of hardness and toughness, including nylon or polyester fibers, in order to effectively remove algae and impurities adhering to the pool walls or bottom; the pool motor 305 can also provide good torque output during operation, driving the bristles 304 to rotate and clean, and the bristles 304 will sweep across the pool walls, ensuring that the bristles 304 can maintain stable rotation even when encountering resistance, and remove sediment.

[0101] In one specific implementation, the brush connecting cylinder 302 is connected in parallel to the end of the brush transmission frame 301. The groove direction of the brush connecting cylinder 302 extends along the axial direction of the brush connecting cylinder 302. The brush rod 303 is installed on the brush connecting cylinder 302, and the bristles 304 are installed on the brush rod 303 and can extend in parallel along the groove of the brush connecting cylinder 302.

[0102] Since the bottom wall of the pool is usually a vertical or near-vertical plane, the parallel-installed brush connecting cylinder 302 can ensure that the brush bristles 304 are completely in contact with the side wall of the pool. The brush pool motor 305 drives the brush rod 303 to rotate and sweep the side brush bristles 304, effectively achieving effective coverage and thorough cleaning of the bottom wall surface.

[0103] In one specific implementation, the brush connecting cylinder 302 is vertically connected to the end of the brush transmission frame 301 as brush A, and the brush connecting cylinder 302 is parallel to the end of the brush transmission frame 301 as brush B.

[0104] Specifically, brush A is set at the bottom of the support frame 1, with its bristles 304 located between the fixed guide component 206 and the push spring limiting component, for cleaning and removing algae from the top of the pool.

[0105] Brush A is set at the bottom of both ends of the support frame 1, and its bristles 304 are respectively located at both ends of the fixed guide component 206 and the push spring limiting component, for cleaning and removing algae from the pool wall.

[0107] like Figure 1-9 As shown, this embodiment discloses an algae removal system for a pool, including: a pool brush and an identification system, wherein the identification system is disposed above the pool brush;

[0108] The recognition system includes a bracket and a camera 6;

[0109] The bracket is a fixed bracket, and camera 6 is mounted on the fixed bracket to identify algae on the pool wall;

[0110] Alternatively, the support can be a movable support, with camera 6 mounted on the movable support and moving to identify algae on the pool wall.

[0111] Specifically, after the camera 6 identifies the location of algae on the pool wall, it feeds back to the brush motor 305 of brush A and brush B, thereby selecting and adjusting the cleaning of algae on the pool wall or top. It can design the brushing path and intensity according to the overall condition of the pool, which can reduce ineffective cleaning, speed up the cleaning process, and save resources.

[0112] Example 4

[0113] like Figure 1-9 As shown in the figure, this embodiment discloses a method for cleaning algae, the cleaning method including:

[0114] S1: The camera 6 on the top of the support frame 1 and / or the camera 6 of the recognition system perform video recognition on the pool wall and transmit the recognized video data to the control center;

[0115] S2: The control center detects the video data images based on the SUSAN operator, calculates the location area of ​​algae pixels on each image of the pool according to the RGB color difference formula, summarizes and calibrates the actual size and position represented by each pixel, and transmits the summarized and calibrated data to the internal AI system for intelligent analysis.

[0116] S3: The AI ​​system calculates the overall algae area size based on the location region size and sets a threshold x.

[0117] S4: When the AI ​​system calculates that the total algae area size is less than or equal to x, the pool wall is cleaned routinely by driving cleaning device 3 and driving device 2.

[0118] S5: When the AI ​​system calculates that the total algae area size is greater than x, the AI ​​system will record the dense algae pixel location area and drive it to that location through the drive device 2. Then, the drive cleaning device 3 will perform a long-term, high-power cleaning of the pool wall.

[0119] Specifically, the control center analyzes the video data identified by camera 6, calculates the location of algae based on the image detected by the SUSAN operator and the RGB color difference formula, and then selects and adjusts the cleaning method. It can design the brushing path and intensity according to the specific situation of the pool, which can reduce ineffective movement, speed up the cleaning process, and thus save resources.

[0120] As one specific implementation method, the cleaning method also includes networked intelligent cleaning:

[0121] L1: A temperature sensor is installed in the water tank and is electrically connected to the control center. The control center synchronously transmits temperature and video data to the cloud platform.

[0122] L2: The cloud platform combines the Internet to analyze the local air temperature, humidity, and regional climate in real time. By comparing the temperature in the pool with the local air temperature and identifying sewage in video data, it analyzes the water quality and determines whether algae are likely to grow.

[0123] L3: When the cloud platform determines that algae are unlikely to grow, it sends a signal to the control center, which then drives the cleaning device 3 and the drive device 2 to perform routine cleaning of the pool walls.

[0124] L4: When the cloud platform determines that algae are likely to grow, it sends a signal to the control center, which then cleans the pool walls in advance by driving the cleaning device 3 and the driving device 2.

[0125] Specifically, by combining cloud platforms with the Internet to analyze the local air temperature, humidity, and regional climate in real time, it is possible to comprehensively judge the possibility of algae growth under the current environmental and water quality conditions. Once a high risk is determined, the early warning system will be triggered immediately. This is an early warning mechanism that can take timely measures such as early cleaning or high-power cleaning to help maintain the ecological balance of the water body and prevent algae from covering the surface of the pool wall.

[0126] Working principle

[0127] During operation, the fixed guide component 206, the push spring limiting component and the drive component are respectively set at the bottom of the support frame 1 and abut against the wall of the secondary sedimentation tank 8. Then the drive component is turned on, so that the cleaning device 3 moves along the wall of the secondary sedimentation tank 8 and cleans. This can effectively enhance the stability of the cleaning operation of the scrubber, ensure that the equipment is stable during operation, reduce vibration, and protect the tank wall from damage.

[0128] When necessary, camera 6 can also be used to identify the location of algae on the pool wall, thereby communicating the image data to the control center. The control center makes intelligent identification based on the image data and issues instructions to control the drive device 2 and the cleaning device 3 respectively, effectively achieving effective coverage and thorough cleaning of algae on the bottom wall surface.
