DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] 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, on which a handle 11 is provided; one side of the decontamination frame 1 is provided with a decontamination lifting structure 2, which is slidably matched with the decontamination frame 1, and a decontamination moving structure 3 is provided on the decontamination lifting structure 2, which is rotatably connected with the decontamination lifting structure 2, and a decontamination rotating structure 4 is provided on the decontamination moving structure 3, and a straight surface decontamination structure 5 and a curved surface decontamination structure 6 are provided on the decontamination rotating structure 4, and the curved surface decontamination structure 6 is slidably connected with the decontamination rotating structure 4, and 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.

[0024] When cleaning the sewage pool, the cleaning frame 1 is placed in the sewage pool, and when the cleaning frame 1 is moved to the side of the pool wall of the sewage pool 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 straight cleaning structure 5 to move horizontally, and the dirt on one side of the pool wall of the sewage pool can be removed back and forth. When the dirt on the other side of the pool wall of the sewage pool needs to be removed, the cleaning rotating structure 4 can drive the straight cleaning structure 5 to move horizontally at any angle of 0-180. The cleaning rotating structure 4 is rotated and paused to an intended position to remove dirt from the other side of the pool wall. When dirt on the curved pool wall is to be removed, the curved surface cleaning structure 6 is adapted to the curved pool wall through the rotation of the cleaning rotating structure 4 to remove dirt from the curved pool wall. When it is necessary to completely remove dirt from 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 dirt from the pool wall.

[0025] 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 slidably 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.

[0026] 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 drives 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 remove scale at 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.

[0027] 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. 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.

[0028] 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 on the lifting plate 22 of the moving mounting seat 33, 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 scrape 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 it is completely scraped.

[0029] By driving the drive motor 82 to drive the straight scraper 51 to move horizontally, the force can be evenly applied during the scraping of the pool wall without causing damage to the scraper, or the position of the scraper being offset to cause damage to the pool wall.

[0030] Specifically, the dirt removal rotating structure 4 includes a mounting frame 41, a rotating frame 42 and a working motor 43. The mounting frame 41 is vertically arranged on the side wall of the movable mounting seat 33, the rotating frame 42 is rotatably connected to the mounting frame 41, and the working motor 43 is located at the top of the mounting frame 41.

[0031] In this embodiment, when scraping the dirt on the directly facing pool wall, the working motor 43 drives the rotating frame 42 to rotate on the mounting frame 41, so that the directly facing scraper 51 is vertically arranged with the directly facing pool wall. At this time, the moving handle 11 drives one side of the directly facing scraper 51 on the dirt removal frame 1 to fit with the side where dirt needs to be removed; 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 to avoid the formation of cleaning dead corners and improve the overall cleaning effect.

[0032] When scraping the curved pool wall, the dirt removal frame 1 is 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.

[0033] Specifically, the direct-surface dirt removal structure 5 includes two direct-surface scrapers 51 , and two mounting grooves are provided on the rotating frame 42 . The two direct-surface scrapers 51 are detachably connected in the two mounting grooves.

[0034] 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. During the scraping process, a single straight surface scraper 51 may cause incomplete cleaning or omission of some areas due to operational errors, scraper shape or slight irregularities of the pool wall.

[0035] The two straight scrapers 51 can compensate for each other when they move simultaneously. An area that may be missed by one straight scraper 51 is likely to be covered by the other straight scraper 51. The two straight scrapers 51 can balance the cleaning pressure on various parts of the pool wall by cooperating with each other, so that every dirt on the pool wall can be scraped off under relatively consistent pressure, ensuring the stability of the cleaning quality.

[0036] 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.

[0037] In this embodiment, when scraping dirt on the curved pool wall, the mobile electric cylinder 60 drives the support seat 61 to move on the rotating frame 42 through two sliding 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 later by placing the curved scraper 692.

[0038] Specifically, the curved surface dirt removal structure 6 also includes a rotating motor 65, a rotating disk 66, a swing rod 67, a swing wheel 68 and a swing plate 69, wherein the rotating motor 65 is located at the bottom of the support seat 61, the rotating disk 66 is mounted on the main shaft of the rotating motor 65, the middle part of the swing rod 67 is rotatably connected to the support seat 61, the swing wheel 68 is rotatably connected to one end of the swing rod 67, two slideways 62 are respectively provided with two sliders 690, a rotatably connected rotating shaft 691 is provided between the two sliders 690, the swing plate 69 is located on the rotating shaft 691, the other end of the swing rod 67 is rotatably connected to the swing plate 69, and a detachable curved surface scraper 692 is provided on the swing plate 69; 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 is provided with an arc groove 72. A locking screw 73 connected to the rotating disk 66 is provided in the arc groove 72, and a locking nut 74 is provided on the locking screw 73 located on the adjusting wheel 71, and the swing wheel 68 slides on the rotating disk 66 and the adjusting wheel 71.

[0039] In this embodiment, when scraping the dirt on the curved pool wall, the rotating motor 65 drives the rotating disk 66 to rotate, and the rotating disk 66 rotates 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 drives 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 drives the curved scraper 692 to swing, thereby scraping the dirt on the curved pool wall; 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. 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, and finally the rotating nut is rotated on the locking screw 73 to fix the position of the adjusting wheel on the rotating disk 66; 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, so that the separation distance between the adjusting wheel and the rotating disk 66 is reduced, and finally the rotating nut is rotated on the locking screw 73 to fix the position of the adjusting wheel on the rotating disk 66; 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 vary greatly. By adjusting the swing amplitude of the curved scraper 692, the curved scraper 692 can be closely attached to the pool walls of various different curvatures. On the same pool wall, there may also be local curvature changes; some pool walls may be elliptical or have some irregular curved parts; the curved scraper 692 with adjustable swing amplitude can flexibly change its state to adapt to the new curvature when encountering these local changes, thereby deeply cleaning the dirt in these complex areas and effectively improving the thoroughness of cleaning; 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-exert 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 the 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 the wear caused by excessive extrusion.

[0040] Specifically, the bottom dirt removal structure 8 includes a driving motor 82, a tensioning wheel 83, two protective covers 84 and two bottom cleaning brush wheels 85. The two bottom cleaning brush wheels 85 are symmetrically rotatably 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 wheel 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 wheel 83 and the two bottom cleaning brush wheels 85.

[0041] 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 dirt removal frame 1 to move forward, so as to drive the two bottom cleaning brush wheels 85 to clean and clean any position of 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 tensioning wheel 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 when the dirt at the bottom of the sewage pool is relatively stubborn, the belt 87 will not slip on the bottom cleaning brush wheel 85.

[0042] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
