Description

Technical Field

[0001] This utility model relates to the field of pool wall cleaning technology, and specifically to a pool wall cleaning device. Background Technology

[0002] In the wastewater treatment process, a secondary sedimentation tank is usually used to settle the mixed liquor of wastewater after biological treatment, separate the mud and water, clarify the mixed liquor and concentrate the sludge, and return the separated sludge to the biological treatment section.

[0003] In the process of water inlet and outlet of secondary sedimentation tanks, overflow weirs and outlet channels are usually set up around the secondary sedimentation tank. Since the actual cross-sectional area of ​​the secondary sedimentation tank is smaller than the designed cross-sectional area, the water level difference is used to overflow the upper clarified mixed liquor to achieve the water outlet effect. However, the mixed liquor in the secondary sedimentation tank is rich in a large amount of organic nutrients and algae. A lot of moss and algae often appear on the weir plate, the inner and outer walls of the outlet channel, the bottom of the tank and the water. The accumulation of a large amount of green algae causes the weir plate and the outlet triangular weir to be blocked. If a lot of dirt is not cleaned in time, it will affect the quality of the effluent to a certain extent and affect the appearance of the tank surface.

[0004] Currently, the cleaning of secondary sedimentation tanks mainly involves cleaning the top wall of the overflow weir, the walls of the flow channel, and the bottom wall of the tank. The current method of manual back-and-forth brushing is inefficient, has high labor costs, and also carries the safety risks of workers wading in the water. Utility Model Content

[0005] This utility model provides a pool wall cleaning device, which aims to improve cleaning efficiency and reduce labor costs.

[0006] This utility model is achieved through the following technical solution: a pool wall cleaning device, including a hanging arm, a bracket, and a top wall cleaning unit, a side wall cleaning unit, and a bottom wall cleaning unit connected to the bracket and respectively cleaning the top wall, side wall, and bottom wall of the pool;

[0007] The top wall cleaning unit includes a top wall brush roller and a connecting frame. One end of the connecting frame is connected to the bracket, and both ends of the top wall brush roller are rotatably connected to the two sides of the connecting frame, respectively.

[0008] The bracket is connected to the hanging arm. The side wall cleaning unit includes a side wall brush roller and a connecting rod. One end of the connecting rod is rotatably connected to the bracket, and the other end of the connecting rod is coaxially connected to the side wall brush roller.

[0009] The bottom wall cleaning unit includes a central rod and a bottom wall brush roller. The bottom wall brush roller is rotatably connected to the bottom of the central rod, and the top of the central rod is connected to the bracket.

[0010] The sidewall brush roller, the top wall brush roller, and the bottom wall brush roller are respectively circumferentially connected with sidewall bristles, top wall bristles, and bottom wall bristles.

[0011] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0012] In this solution, the boom is operated manually or by automated machinery. The boom moves the top wall cleaning unit, side wall cleaning unit, and bottom wall cleaning unit along the pool wall to be cleaned. While moving, the top of the overflow dike, the walls of the flow channel, and the bottom of the pool are cleaned simultaneously, effectively improving cleaning efficiency. Moreover, this eliminates the need for manual entry into the pool for cleaning. Operators can move the boom from outside the pool by pushing or pulling it, which effectively reduces the danger of manual operation, lowers labor costs, and is easy to operate.

[0013] Furthermore, the connecting frame includes a vertical rod, a horizontal plate, and side plates. One end of the vertical rod is vertically fixedly connected to the support, and the other end of the vertical rod is vertically fixedly connected to the horizontal plate. Two side plates are provided, and the two side plates are respectively vertically fixedly connected to the two sides of the horizontal plate. The two sides of the top wall brush roller are respectively rotatably connected to the two side plates.

[0014] The shape and structure of the connecting frame in this solution facilitates the installation of the top wall brush roller, allowing the top wall brush roller to clean the top of the pool while rotating on top of the pool using the top wall bristles.

[0015] Furthermore, the bottom of the sidewall brush roller is connected to brush bristles.

[0016] This solution not only has side wall bristles for cleaning the pool wall in the circumference of the side wall brush roller, but also connects bristles to the bottom of the side wall brush roller, so that the area below the side wall brush roller can also be cleaned, reducing blind spots and thus improving the cleaning effect on the entire area to be cleaned.

[0017] Furthermore, the sidewall bristles are provided in multiple layers, and the multiple layers of sidewall bristles are distributed sequentially along the axial direction of the sidewall brush roller. Each layer of sidewall bristles is provided in multiple ways, and the multiple sidewall bristles in each layer are evenly distributed along the circumference of the sidewall brush roller.

[0018] The sidewall bristles in this design are multi-layered, and the bristles in the multiple layers are evenly distributed circumferentially, which increases the cleaning area and thus improves the cleaning effect.

[0019] Furthermore, the multiple sidewall bristles in each layer are arranged in an alternating pattern.

[0020] In this design, the multiple sidewall bristles of each layer are staggered, which allows the brushing area formed by the multiple sidewall bristles of each layer to be larger, resulting in better cleaning effect and reducing blind spots in brushing.

[0021] Furthermore, a traveling wheel is rotatably connected to the bottom of the intermediate rod.

[0022] The use of wheels in this design reduces the resistance to movement of the entire cleaning device, making it easier to move the device and reducing scratches on the bottom of the pool.

[0023] Furthermore, side frames are fixedly connected to the bottom two sides of the intermediate rod, the walking wheel is rotatably connected to the two side frames through a rotating shaft, and the bottom wall brush roller is coaxially fixedly connected to the rotating shaft.

[0024] In this design, the side frame facilitates the installation of the walking wheels, while the bottom wall brush roller is installed with the rotating shaft. This allows the bottom wall brush roller to rotate via the rotating shaft during the movement of the walking wheels, thereby achieving the function of cleaning the bottom of the pool.

[0025] Furthermore, the support includes a first support, a second support, and a connecting platform. The first support and the second support are located on both sides of the connecting platform and connected to both sides of the connecting platform. The connecting platform is connected to the hanging arm. The top wall cleaning unit and the side wall cleaning unit are each provided in two sets. The two sets of top wall cleaning units and the two sets of side wall cleaning units are respectively connected to the first support and the second support. The bottom wall cleaning unit is connected to the connecting platform.

[0026] In this solution, there are two sets of top wall cleaning units and two sets of side wall cleaning units, which can clean both sides of the pool or tank at the same time, as well as the top of both sides, thus improving cleaning efficiency.

[0027] Furthermore, both the first bracket and the second bracket are connected to the connecting platform with elastic elements, and both the first bracket and the second bracket are horizontally slidingly engaged with the hanging arm.

[0028] In this solution, the first and second supports are connected to the connecting platform via elastic elements. This allows the top wall cleaning unit and the side wall cleaning unit to automatically adjust themselves to clean pools or tanks with different widths. This ensures that the top wall cleaning unit and the side wall cleaning unit always contact the top and side walls for effective cleaning, thus adapting to different widths within the pool or tank and making the system more flexible to use.

[0029] Furthermore, two guide grooves are provided at the bottom of the hanging arm, and guide blocks are fixedly connected to the top of both the first bracket and the second bracket. The guide blocks are inserted into the guide grooves and slide in cooperation with the guide grooves.

[0030] In this design, the cooperation between the guide groove and the guide block can improve the stability and accuracy of the movement of the first and second supports. Attached Figure Description

Specifically, the connecting frame 6 includes a vertical rod 603, a horizontal plate 602, and a side plate 601. One end of the vertical rod 603 is vertically fixedly connected to the bracket 2, and the other end of the vertical rod 603 is vertically fixedly connected to the horizontal plate 602. In this embodiment, both ends of the vertical rod 603 are threadedly connected to the bracket 2 and the horizontal plate 602, which facilitates installation and disassembly.

[0042] In this embodiment, there are two side plates 601. The two side plates 601 are respectively vertically fixed to the two sides of the horizontal plate 602. In this embodiment, the side plates 601 and the horizontal plate 602 are integrally formed, welded and fixed or connected by screws. The two sides of the top wall brush roller 8 are respectively rotatably connected to the two side plates 601 through bearings.

[0043] The sidewall cleaning unit includes a sidewall brush roller 10 and a connecting rod 9. One end of the connecting rod 9 is rotatably connected to the bracket 2 via a bearing, and the other end of the connecting rod 9 is coaxially connected to the sidewall brush roller 10. In this embodiment, the connecting rod 9 is welded and fixed to the top end of the sidewall brush roller 10.

[0044] The bottom wall cleaning unit includes a central rod 5 and a bottom wall brush roller 14. The bottom wall brush roller 14 is rotatably connected to the bottom of the central rod 5, and the top of the central rod 5 is connected to the bracket 2. In this embodiment, the top of the central rod 5 is threaded, welded, or fixed to the connecting platform 203 in the bracket 2. In this embodiment, a traveling wheel 13 is rotatably connected to the bottom of the central rod 5. Specifically, side frames 12 are welded or screwed to both sides of the bottom of the central rod 5. The traveling wheel 13 is rotatably connected to the two side frames 12 through a rotating shaft 131 via bearings. There are two bottom wall brush rollers 14. The two bottom wall brush rollers 14 are coaxially fixed to both ends of the rotating shaft 131. In this embodiment, the bottom wall brush rollers 14 are coaxially welded, screwed, threaded, or connected to the rotating shaft 131.

[0045] In this embodiment, the side wall brush roller 10, the top wall brush roller 8 and the bottom wall brush roller 14 are respectively connected to the side wall bristles 11, the top wall bristles 801 and the bottom wall bristles 141 in the circumferential direction.

[0046] In this embodiment, the side wall bristles 11, top wall bristles 801, and bottom wall bristles 141 can be special bristles for cleaning pool walls available on the market, with the bristles evenly distributed on each brush roller.

[0047] Furthermore, in another embodiment of this application, the sidewall bristles 11 are provided in multiple layers, and the multiple layers of sidewall bristles 11 are distributed sequentially along the axial direction of the sidewall brush roller 10. Each layer of sidewall bristles 11 has multiple bristles, and the multiple sidewall bristles 11 in each layer are evenly distributed along the circumference of the sidewall brush roller 10. Moreover, the multiple sidewall bristles 11 in each layer are staggered. Since the area of ​​the sidewall is usually large and the cleaning is difficult, this embodiment arranges the multiple sidewall bristles 11 in each layer in a staggered manner. This can improve the comprehensiveness of the coverage of the sidewall bristles 11, reduce cleaning dead corners during the cleaning process, and reduce the number of sidewall bristles 11, thereby reducing costs.

[0048] The specific implementation process is as follows:

[0049] Combination Figure 2 As shown, a pool wall cleaning device according to this application is placed in the pool to be cleaned (such as the outlet channel of a secondary sedimentation tank). The top wall brush rollers are positioned on both sides of the top of the pool, with the top wall bristles 801 in contact with the top wall of the pool. The side wall brush rollers 10 are positioned on the two inner side walls of the pool, with the side wall bristles 11 in contact with the inner side walls of the pool. The bottom wall brush rollers 14 have bottom wall bristles 141 in contact with the bottom wall of the pool. The hanging arm 1 is positioned facing outwards from the pool. The operator pushes or pulls the hanging arm 1 to move it, thereby moving the entire device along the toothed groove. During the movement, the top wall brush rollers 8, side wall brush rollers 10, and bottom wall brush rollers 14 all roll, and the bristles 7 on each brush roller simultaneously clean the top, side walls, and bottom wall, resulting in high efficiency. Of course, in practice, an automated machine can also be used to drive the hanging arm 1 to move, thereby achieving the purpose of automatic cleaning.

[0050] Example 2, the difference between this example and Example 1 is as follows: Figure 3 As shown, both the first bracket 201 and the second bracket 202 are connected to the connecting platform 203 by elastic elements 15. In this embodiment, the elastic element 15 is a tension spring. Rings (not shown in the figure) are welded and fixed on both sides of the connecting platform 203 and on the side of the first bracket 201 and the second bracket 202 facing the connecting platform 203. The hooks at both ends of the tension spring are hooked into the rings on the connecting platform 203 and the first bracket 201 or the second bracket 202, thereby realizing the installation of the tension spring.

[0051] The first bracket 201 and the second bracket 202 are both horizontally slidingly engaged with the hanging arm 1. Specifically, the bottom of the hanging arm 1 has two guide grooves 101. The tops of the first bracket 201 and the second bracket 202 are both welded and fixedly connected or threaded and fixedly connected with guide blocks 102 in other ways. In this embodiment, the guide blocks 102 are inserted into the guide grooves 101 and slidely engaged with the guide grooves 101.

[0052] In this embodiment, the first bracket 201 and the second bracket 202 are connected to the connecting platform 203 through the elastic element 15. This allows the top wall cleaning unit and the side wall cleaning unit to automatically adjust themselves when cleaning pools or tanks with different widths. This ensures that the top wall cleaning unit and the side wall cleaning unit can always contact the top and side walls for effective cleaning, thus adapting to different widths inside the pool or tank, making it more flexible and practical to use.

[0053] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
