DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a municipal sewage pool bottom decontamination and descaling device, including a decontamination frame 1, the decontamination frame 1 is provided with a handle 11; a decontamination lifting structure 2 is provided on one side of the decontamination frame 1, the decontamination lifting structure 2 is slidably matched with the decontamination frame 1, the decontamination lifting structure 2 is provided with a decontamination moving structure 3, the decontamination moving structure 3 is rotatably connected to the decontamination lifting structure 2, the decontamination moving structure 3 is provided with a decontamination rotating structure 4, the decontamination rotating structure 4 is provided with a straight surface decontamination structure 5 and a curved surface decontamination structure 6, the curved surface decontamination structure 6 is slidably connected to the decontamination rotating structure 4, the decontamination moving structure 3 drives the straight surface decontamination structure 5 to move horizontally to perform decontamination work; the bottom of the decontamination frame 1 is provided with a bottom decontamination structure 8.

[0034] When cleaning the sewage pool, the cleaning frame 1 is placed in the sewage pool. When the cleaning frame 1 is moved to the side of the pool wall by the handle 11, the bottom cleaning structure 8 can remove the dirt at the bottom of the sewage pool, and the cleaning moving structure 3 drives the surface cleaning structure 5 to move horizontally, and can remove the dirt on one side of the pool wall of the sewage pool back and forth. When the dirt on the other side of the pool wall of the sewage pool needs to be cleaned, the cleaning rotating structure 4 can drive the surface cleaning structure 5 to move horizontally at any angle of 0-180 degrees. The cleaning rotating structure 4 rotates and pauses at an arbitrary position to clean the other side of the pool wall. When removing dirt on the curved pool wall, the curved surface cleaning structure 6 is adapted to the curved pool wall through the rotation of the cleaning rotating structure 4 to remove the dirt on the curved pool wall. When it is necessary to completely clean the dirt on the straight or curved pool wall, the cleaning lifting structure 2 can be used to drive the straight surface cleaning structure 5 and the curved surface cleaning structure 6 to move up and down to completely remove the dirt from the pool wall.

[0035] Specifically, the dirt removal lifting structure 2 includes a lifting motor 21, a lifting plate 22 and two slide rails 23. The two slide rails 23 are symmetrically arranged on the side walls of the dirt removal frame 1. The two ends of the lifting plate 22 are slidingly connected to the two slide rails 23. The dirt removal frame 1 is respectively provided with an upper sprocket 24 and a lower sprocket 25 that are rotatably connected. The upper sprocket 24 and the lower sprocket 25 are respectively provided with a chain 26. The chain 26 is connected to the lifting plate 22. The lifting motor 21 is located above the dirt removal frame 1 and is transmission-connected to the upper sprocket 24.

[0036] In this embodiment, when the dirt on the wall of the sewage pool is completely removed, the lifting motor 21 drives the upper sprocket 24 to rotate, and the rotation of the upper sprocket 24 will drive the lower sprocket 25 to rotate through the chain 26, thereby driving the lifting plate 22 to move up and down on the two slide rails 23 and stop. In the process of removing the dirt on the pool wall, after the dirt on the sewage pool on the same plane is removed, the corresponding curved scraper 692 and the straight scraper 51 can be driven to move up and down, so as to perform descaling work on different positions on the pool wall of the sewage pool, which can cover all height ranges of the pool wall, making the cleaning effect more comprehensive and improving the cleaning efficiency.

[0037] Specifically, the dirt removal mobile structure 3 includes a mobile motor 31, a mobile screw 32 and a mobile mounting seat 33. A slide groove 34 is provided on the lifting plate 22, and the mobile mounting seat 33 is slidably connected in the slide groove 34. The mobile motor 31 is located on the side wall of the lifting plate 22. The mobile screw 32 is rotatably connected to the lifting plate 22 and is connected to the main shaft of the mobile motor 31. The mobile mounting seat 33 is threadedly connected to the mobile screw 32.

[0038] In this embodiment, when scraping the dirt on the pool wall, the moving motor 31 drives the moving screw 32 to move horizontally in the slide groove 34 of the moving mounting seat 33 on the lifting plate 22, thereby driving the straight scraper 51 on the moving mounting seat 33 to move horizontally from one end of the dirt removal frame 1 to the other end to perform reciprocating work, and scraping the dirt on the same area of ​​the dirt removal frame 1 on the sewage pool. When scraping the dirt on another area, the position of the straight scraper 51 can be driven by the mobile dirt removal frame 1 to move, and the dirt in other places of the sewage pool can be scraped until the whole area is scraped off.

[0039] The drive motor 82 drives the straight scraper 51 to move horizontally, so that during the process of scraping the pool wall, the force is evenly applied without causing damage to the scraper, and the position of the scraper is shifted to avoid damage to the pool wall.

[0040] Specifically, the dirt removal rotating structure 4 includes an installation frame 41, a rotating frame 42 and a working motor 43. The installation frame 41 is vertically arranged on the side wall of the movable mounting seat 33, the rotating frame 42 is rotatably connected to the installation frame 41, and the working motor 43 is located at the top of the installation frame 41.

[0041] In this embodiment, when scraping dirt on the direct-facing pool wall, the working motor 43 drives the rotating frame 42 to rotate on the mounting frame 41, so that the direct-facing scraper 51 is perpendicular to the direct-facing pool wall. At this time, the moving handle 11 drives one side of the direct-facing scraper 51 on the dirt removal frame 1 to fit the side where dirt needs to be removed.

[0042] During the scraping process, the angle of the straight scraper 51 can be rotated by the working motor 43. The rotation can make the straight scraper 51 better fit the surface of the pool wall. When encountering a raised part, the straight scraper 51 can adjust the angle by rotation to ensure that the straight scraper 51 is in close contact with the pool wall, thereby completely scraping off the dirt; for the recessed parts, the rotated straight scraper 51 can also penetrate deeper into them, avoiding the formation of cleaning dead corners and improving the overall cleaning effect.

[0043] When scraping the curved pool wall, the cleaning frame 1 is placed across the curved surface, and the working motor 43 drives the rotating frame 42 to swing on the mounting frame 41, so that the curved pool wall can be scraped initially to remove some large dirt.

[0044] Specifically, the direct-surface decontamination structure 5 includes two direct-surface scrapers 51 . The rotating frame 42 is provided with two mounting grooves, and the two direct-surface scrapers 51 are detachably connected in the two mounting grooves.

[0045] In this embodiment, during the process of scraping dirt on the straight surface of the pool wall, the two straight surface scrapers 51 can move simultaneously to scrape the dirt. When encountering more stubborn dirt, the two straight surface scrapers 51 can act simultaneously to generate a stronger scraping force. A single straight surface scraper 51 may not clean thoroughly or miss some areas during the scraping process due to operational errors, scraper shape or minor irregularities of the pool wall.

[0046] The simultaneous movement of the two straight scrapers 51 can compensate for each other. The area that one straight scraper 51 may miss is likely to be covered by the other straight scraper 51. The simultaneous movement of the two straight scrapers 51 can make the cleaning pressure on various parts of the pool wall more uniform. The existence of the two straight scrapers 51 can balance the pressure distribution through mutual cooperation, so that every dirt on the pool wall can be scraped off under relatively consistent pressure, ensuring the stability of the cleaning quality.

[0047] Specifically, the curved surface dirt removal structure 6 includes a mobile electric cylinder 60, a support seat 61, two slides 62 and a connecting frame 63. The mobile electric cylinder 60 is horizontally arranged on the rotating frame 42. The support seat 61 is connected to the telescopic end of the mobile electric cylinder 60. The support seat 61 is provided with a slide rod 64 that slides with the rotating frame 42. The two slides 62 are symmetrically arranged on the rotating frame 42.

[0048] In this embodiment, when scraping dirt from the curved pool wall, the mobile electric cylinder 60 drives the support seat 61 to move on the rotating frame 42 through two slide rods 64, and thus moves through the position of the connecting frame 63. The movement of the connecting frame 63 drives the corresponding slider 690 to move on the slide 62, so that the position of the curved scraper 692 can be moved to the curved pool wall, so that the dirt on the curved pool wall can be scraped off subsequently by placing the curved scraper 692.

[0049] Specifically, the curved surface decontamination structure 6 also includes a rotating motor 65, a rotating disk 66, a swinging rod 67, a swinging wheel 68 and a swinging plate 69. The rotating motor 65 is located at the bottom of the support base 61, the rotating disk 66 is mounted on the main shaft of the rotating motor 65, the middle part of the swinging rod 67 is rotatably connected to the support base 61, the swinging wheel 68 is rotatably connected to one end of the swinging rod 67, two slideways 62 are respectively provided with two sliders 690, a rotating shaft 691 is rotatably connected between the two sliders 690, the swinging plate 69 is located on the rotating shaft 691, the other end of the swinging rod 67 is rotatably connected to the swinging plate 69, and a detachable curved scraper 692 is provided on the swinging plate 69;

[0050] The rotating disk 66 is provided with three amplitude adjustment members 7, each of which includes an adjustment wheel 71, which is rotatably connected to the rotating disk 66, and an arcuate groove 72 is provided on the adjustment wheel 71, in which a locking screw 73 connected to the rotating disk 66 is provided, and the locking screw 73 is located on the adjustment wheel 71 and a locking nut 74 is provided. The swing wheel 68 slides on the rotating disk 66 and the adjustment wheel 71.

[0051] In this embodiment, when scraping dirt on the curved pool wall, the rotating motor 65 drives the rotating disk 66 to rotate. The rotation of the rotating disk 66 will rotate through the three adjusting wheels 71 on the rotating disk 66, thereby driving the swing wheel 68 to rotate on the rotating disk 66 and the three adjusting wheels 71. When the swing wheel 68 encounters the adjusting wheel 71, it will drive the swing rod 67 to swing on the support seat 61, thereby driving the swing plate 69 to swing on the two sliders 690 through the rotating shaft 691. The swing of the swing plate 69 will drive the curved scraper 692 to swing, thereby scraping the dirt on the curved pool wall;

[0052] When scraping the curved pool wall with different curvatures, the angular position of the adjusting wheel on the rotating disk 66 can be adjusted to increase or decrease the swing angle of the swing rod 67. When making adjustments, the locking nut 74 is loosened to allow the arc groove 72 on the adjusting wheel 71 to rotate along the locking screw 73.

[0053] When scraping dirt on the curved pool wall with a large arc, the adjusting wheel is rotated toward the outside of the rotating disk 66 to increase the separation distance between the adjusting wheel and the rotating disk 66. Finally, the rotating nut is rotated on the locking screw 73 to fix the position of the adjusting wheel on the rotating disk 66.

[0054] When scraping dirt on the curved pool wall with a small arc, the adjusting wheel is rotated toward the inner side of the rotating disk 66 to reduce the separation distance between the adjusting wheel and the rotating disk 66. Finally, the rotating nut is rotated on the locking screw 73 to fix the position of the adjusting wheel on the rotating disk 66.

[0055] In the process of scraping dirt on the curved pool wall, the swing amplitude of the curved scraper 692 can be adjusted according to the different curvatures of the curved pool wall, so as to be suitable for scraping dirt on the curved pool wall with different curvatures. The curvatures of the curved pool walls of different sewage pools are very different.

[0056] By adjusting the swing amplitude of the curved scraper 692, the curved scraper 692 can closely fit the pool wall with various curvatures. On the same pool wall, there may be local curvature changes; some pool walls may be elliptical or have some irregular curved parts. When encountering these local changes, the curved scraper 692 with adjustable swing amplitude can flexibly change its state to adapt to the new curvature, thereby deeply cleaning the dirt in these complex areas and effectively improving the thoroughness of cleaning.

[0057] If the swing amplitude of the curved scraper 692 cannot be adjusted, when scraping dirt on the pool wall with a large curvature change, the scraper may over-extrude the pool wall because it cannot adapt to the curvature; this will cause the curved scraper 692 to be locally under excessive pressure, increasing wear; while the curved scraper 692 with adjustable swing amplitude can reasonably distribute pressure according to the curvature of the pool wall, so that the contact pressure between the curved scraper 692 and the pool wall is maintained within an appropriate range, reducing wear caused by excessive extrusion.

[0058] Specifically, the bottom dirt removal structure 8 includes a driving motor 82, a tensioning pulley 83, two protective covers 84 and two bottom cleaning brush wheels 85. The two bottom cleaning brush wheels 85 are symmetrically connected to the bottom of the dirt removal frame 1. The two protective covers 84 are symmetrically arranged on the dirt removal frame 1. The protective covers 84 are arranged above the bottom cleaning brush wheels 85. A motor seat 86 is provided at the bottom of the driving motor 82. The driving motor 82 is connected to the dirt removal frame 1 through the motor seat 86. The tensioning pulley 83 is rotatably connected to the dirt removal frame 1. The main shaft of the driving motor 82 is provided with a belt 87 that is sleeved on the tensioning pulley 83 and the two bottom cleaning brush wheels 85.

[0059] In this embodiment, when cleaning the bottom of the sewage pool, the driving motor 82 drives the two bottom cleaning brush wheels 85 to rotate synchronously through the belt 87, and pushes the decontamination frame 1 forward, which can drive the two bottom cleaning brush wheels 85 to clean and clean any position on the bottom of the sewage pool and scrape off the dirt at the bottom of the sewage pool. The protective cover 84 can prevent the splashing of sewage during the cleaning process, and the setting of the tensioner 83 ensures that when the driving motor 82 drives the two bottom cleaning brush wheels 85 to rotate through the belt 87, the belt 87 can maintain appropriate tension to ensure that the two bottom cleaning brush wheels 85 can rotate synchronously and that the belt 87 will not slip on the bottom cleaning brush wheel 85 when the dirt at the bottom of the sewage pool is relatively stubborn.

[0060] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
