[0055] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0056] Embodiment 1:

[0057] like Figure 1 , Figure 2 As shown, the present invention provides a stainless steel water tank with self-cleaning and sewage discharge, comprising:

[0058] A water tank 1, a rotating shaft 2 is slidably arranged at the center of the water tank 1, and a sewage outlet 5 is arranged at the bottom of the water tank 1;

[0059] A lifting unit, which is arranged at one side of the water tank 1 and is used to drive the rotating shaft 2 to slide in a vertical direction;

[0060] A cleaning unit is connected to the rotating shaft 2. The cleaning unit includes a spray head 3 and a cleaning roller 4. The spray head 3 is used to spray the cleaning liquid onto the inner wall of the water tank 1. The cleaning roller 4 is used to scrape off the attachments on the inner wall of the water tank 1.

[0061] The control unit is used to control the cleaning unit to spray and clean alternately.

[0062] The working principle and beneficial effects of the above technical solution are:

[0063] When cleaning the stainless steel water tank, start the lifting unit to drive the rotating shaft 2 to slide along the center of the water tank 1, so that the cleaning unit can perform cleaning operations at different heights in the water tank 1; the control unit controls the cleaning unit to work according to the preset cleaning program, and the rotating shaft 2 rotates to drive the spray head 3 to rotate, spraying the cleaning liquid onto the inner wall of the water tank 1 to wet and preliminarily decontaminate the inner wall, and then controls the rotating shaft 2 to drive the cleaning roller 4 to rotate and contact the inner wall of the water tank 1 to scrape off the loose attachments after being soaked by the cleaning liquid. The controller controls the above spraying and cleaning operations to be performed alternately, accompanied by the up and down movement of the lifting unit, to clean the inner wall of the water tank 1, and the sewage generated after cleaning falls to the bottom of the water tank 1 and is discharged through the sewage outlet 5.

[0064] Through the above-mentioned structural design, a cleaning method combining spraying of cleaning liquid and rotating scraping of cleaning rollers is adopted, and the two operation modes are performed alternately to ensure that the attachments can be effectively wetted before each cleaning, and the scraped dirt is promptly washed to the bottom of the water tank, avoiding the cleaning roller 4 from affecting the spraying and wetting effect during synchronous operation; effectively realize automatic cleaning and sewage discharge of the water tank, improve cleaning efficiency, ensure the water quality of the liquid stored in the water tank, and extend the service life of the water tank.

[0065] Embodiment 2:

[0066] like Figure 1 , Figure 2 As shown, based on the above embodiment 1, the lifting unit includes:

[0067] A lifting hydraulic cylinder 7, which is installed on the outer wall of the water tank 1 and is arranged vertically;

[0068] A lifting arm 6 , one end of which is connected to the hydraulic rod of the lifting hydraulic cylinder 7 and is located above the water tank 1 , and the other end of which is connected to the top of the rotating shaft 2 .

[0069] The working principle and beneficial effects of the above technical solution are:

[0070] The lifting hydraulic cylinder 7 is installed on the outer wall of the water tank and is arranged vertically. When in use, it drives the hydraulic rod to perform linear lifting motion, driving the lifting arm 6 to move, and then realizing the vertical movement of the rotating shaft 2, so that the cleaning unit connected to the rotating shaft 2 can reach different height positions of the water tank, thereby realizing comprehensive cleaning of various positions on the inner wall of the water tank.

[0071] Embodiment 3:

[0072] like Figure 1 , Figure 2As shown, on the basis of the above-mentioned embodiment 2, the reducer 11 is installed on the lifting arm 6, the input end of the reducer 11 is connected to the motor, and the output end of the reducer 11 is connected to the rotating shaft 2; a cleaning liquid channel is arranged at the center of the rotating shaft 2, one end of the cleaning liquid channel is connected to the liquid supply device through a pipeline, and the other end is connected to the spray head 3 through a pipeline; a plurality of support arms 12 are evenly connected to the bottom end of the rotating shaft 2, and the cleaning unit is installed on the support arm 12.

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] When the cleaning unit is in use, the controller starts the motor, and transmits the rotation of the motor to the shaft 2 through the reducer 11, so that the shaft 2 rotates to provide rotational power for the cleaning unit; the liquid supply device transports the cleaning liquid to the cleaning liquid channel in the center of the shaft through the pipeline, and then sprays it out through the spray head; the support arm 12 is evenly connected to the bottom end of the shaft 2, and is used to install the cleaning unit, so that the cleaning unit can rotate and rise and fall with the shaft 2.

[0075] Embodiment 4:

[0076] like Figure 3-Figure 7 As shown, based on the above embodiment 3, the cleaning unit includes:

[0077] A telescopic arm 13, one end of the telescopic arm 13 is slidably connected to a slide groove 14 at the end of the support arm 12, and a spring is connected between the telescopic arm 13 and the bottom of the slide groove 14, and a cleaning roller 4 is connected to the bottom of the other end of the telescopic arm 13;

[0078] The magnetic block group includes a permanent magnet 15 and an electromagnet 16. The permanent magnet 15 is connected to one end of the telescopic arm 13 located in the slide slot 14. The electromagnet 16 is connected to the bottom of the slide slot 14. When the electromagnet 16 is energized, it generates a repulsive force on the permanent magnet 15.

[0079] The working principle and beneficial effects of the above technical solution are:

[0080] During the cleaning process, the telescopic arm 13 is stored in the slide 14 under the action of the spring. When the spraying operation is performed, the rotating shaft 2 is driven to rotate. Under the action of centrifugal force, the telescopic arm 13 slightly extends outward, but the cleaning roller 4 does not contact the inner wall of the water tank 1. The cleaning liquid can be sprayed onto the inner wall of the water tank 1, and the cleaning roller 4 will not block the flow of the cleaning liquid. When the cleaning operation is performed, the electromagnet 16 is energized, and the electromagnet 16 and the permanent magnet 15 generate a repulsive force, further pushing the telescopic arm 13 to slide outward, so that the cleaning roller 4 is tightly attached to the inner wall of the water tank 1, and the attached objects are scraped off as the rotating shaft 2 rotates. Through the above structural design, the extension degree of the telescopic arm 13 is adjusted at different stages of the cleaning process. During the spraying operation, the cleaning roller 4 does not hinder the flow of the cleaning liquid. During the cleaning operation, the cleaning roller 4 is tightly attached to the inner wall of the water tank 1, ensuring flexible switching of the cleaning stages.

[0081] Embodiment 5:

[0082] like Figure 3-Figure 7 As shown, based on the above embodiment 4, the cleaning unit further includes:

[0083] A box body 17, the box body 17 is connected to the top of the telescopic arm 13, and a cover plate 22 is provided on the box body 17;

[0084] The support platform 18 is slidably connected to the box body 17, the sprinkler head 3 is obliquely installed above the support platform 18, and the bottom end of the support platform 18 is connected to a sliding column 21;

[0085] The sleeve 19 is connected to the bottom end of the box 17, and the bottom end of the slide post 21 is slidably connected in the sleeve 19. A spring is sleeved on the sleeve 19 and the slide post 21, and the spring abuts between the bottom wall of the box 17 and the support platform 18;

[0086] A cross bar 23, the cross bar 23 is connected to a side of the box body 17 away from the side wall of the water tank 1;

[0087] Gear 24, gear 24 is rotatably connected to cross bar 23;

[0088] A rack seat 25, the rack seat 25 is connected to the support arm 12, a rack is provided on the top of the rack seat 25, and the gear 24 is meshed and connected with the rack;

[0089] The bottom end of the rotating rod 26 is connected to the rotating shaft of the gear 24 , and the top end of the rotating rod 26 is connected to the cover plate 22 . After the cover plate 22 rotates, it is covered on the top end of the box body 17 .

[0090] The working principle and beneficial effects of the above technical solution are:

[0091] During the cleaning process, when the spraying operation is performed, the telescopic arm 13 is stored in the slide groove 14 under the action of the spring; the cover plate 22 is opened to expose the spray head 3; the controller starts the liquid supply device to transport the cleaning liquid into the spray head 3, and sprays the cleaning liquid to the inner wall of the water tank 1 through the spray head 3; the spray head 3 is provided with two spraying areas, the spray hole on the first spraying area is angled toward the inner wall of the water tank 1, and the spray hole on the second spraying area is angled toward the cleaning roller 4, so that the inner wall of the water tank 1 and the cleaning roller 4 can be sprayed at the same time. When performing cleaning operations, the telescopic arm 13 is extended to make the cleaning roller 4 close to the inner wall of the water tank 1. The telescopic arm 13 drives the box 17 to move, and the crossbar 23 moves with the box 17. The rack engages with the gear 24, driving the gear 24 to rotate, thereby rotating the rotating rod 26, and the cover plate 22 connected to the rotating rod 26 rotates and seals the top of the box 17; when the cover plate 17 falls, it squeezes the spray head 3 to store it in the box 17, and at the same time pushes the support platform 18 down, and the slide column 21 slides along the sleeve 19 and stores energy in the spring. When the spraying operation is performed again, the telescopic arm 13 is retracted, the gear 24 and the rotating rod 26 rotate in the opposite direction, the cover plate 22 is opened, and the support platform 18 is reset upward under the action of the spring to expose the spray head 3 again. In addition to other components of the cleaning unit except the box 17, a protective film is provided to prevent the splashing of the cleaning liquid.

[0092] Through the above-mentioned structural design, during the spraying operation, the cover 22 automatically opens to expose the spray head 3, and a preset distance is maintained between the spray head 3 and the inner wall, and the inner wall of the water tank 1 and the cleaning roller 4 are sprayed at the same time; during the cleaning operation, the cover 22 automatically closes to store the spray head 3; it effectively prevents the cleaning liquid from backwashing when the spraying distance is close to the inner wall of the water tank 1; and prevents sewage from splashing onto the spray head 3 during the cleaning process, causing crystallization and clogging of the spray head 3, thereby achieving effective protection of the spray head 3 and ensuring the normal use of the cleaning unit; during the cleaning operation, the box body 17 and the spray head 3 move outward synchronously with the telescopic arm 13, which helps to move the center of gravity of the cleaning unit outward, increase the centrifugal force, and thereby ensure that the cleaning roller 4 is in stable contact with the inner wall of the water tank 1.

[0093] Embodiment 6:

[0094] like Figure 3-Figure 7 As shown, based on the above embodiment 5, the cleaning unit further includes:

[0095] A slide 27, the slide 27 is connected to the support arm 12 and is disposed close to the rotating shaft 2, and a vertical slide groove 28 is disposed on one side of the slide 27 close to the box body 17;

[0096] A limit rod 29, the limit rod 29 is L-shaped, the horizontal section of the limit rod 29 is slidably connected in the vertical slide groove 28, and a spring is connected between the limit rod 29 and the top of the vertical slide groove 28;

[0097] The push rod 31 is connected to the box body 17 and is arranged close to the rotating shaft 2 . The bottom end of the limiting rod 29 is pressed above the push rod 31 .

[0098] The bottom end of the top rod 31 is set as a conical head, and a magnetic block is embedded in the conical head; an electromagnetic seat 32 is set in the support arm 12, and a conical hole is set in the electromagnetic seat 32, and an electromagnetic block is embedded in the conical hole. When the electromagnetic block is energized, a repulsive force is generated on the magnetic block.

[0099] The working principle and beneficial effects of the above technical solution are:

[0100] When performing the spraying operation, the telescopic arm 13 is stored in the slide 14 under the action of the spring; the limit rod 29 is pressed against the top of the push rod 31. When performing the cleaning operation, the box body 17 drives the push rod 31 to move, the limit rod 29 slides along the push rod 31 to its end, and moves downward under the action of the spring, and the conical head of the limit rod 29 is clamped in the conical hole of the electromagnetic seat 32; the limit rod 29 is limited by the side of the push rod 31 to prevent the cleaning roller 4 from being lifted up when it contacts with attachments with a large protruding height during the cleaning process, so that the cleaning roller 4 is attached to the inner wall of the water tank 1 and has sufficient pressure to ensure the cleaning effect. When the spraying operation is performed again, the electromagnetic block is energized to generate a repulsive force on the conical head, so that the push rod 31 overcomes the spring elastic force and is lifted up. As the box body 17 and the push rod 31 move inward, the push rod 31 contacts the conical surface of the conical head and slides relatively until the conical head returns to the top of the push rod 31.

[0101] Embodiment 7:

[0102] like Figure 3-Figure 7 As shown, on the basis of the above-mentioned embodiment 5, a sealing gasket is arranged between the support platform 18 and the box body 17, and a sealing gasket is arranged at the bottom of the cover plate 22; a negative pressure component is arranged on the box body 17, and the negative pressure component includes:

[0103] Negative pressure box 30, the negative pressure box 30 is installed on the cross bar 23, a piston plate 33 is slidably connected in the negative pressure box 30, and the lower part of the negative pressure box 30 is connected to the lower part of the box body 17 through the air guide pipe 39;

[0104] The screw 34 is rotatably connected to the center of the negative pressure box 30 and is connected to the central threaded hole of the piston plate 33. The top of the screw 34 extends out of the negative pressure box 30. A coil spring is provided at the connection between the screw 34 and the negative pressure box 30.

[0105] The first wire wheel 35 and the second wire wheel 36 , the first wire wheel 35 is connected to the top of the screw rod 34 ; the second wire wheel 36 is connected to the top of the slide seat 27 , and the connecting wire 37 is wound around the first wire wheel 35 and the second wire wheel 36 .

[0106] The second wire wheel 36 can be rotated to any angle and then locked. A handle 38 is connected to the second wire wheel 36 .

[0107] The working principle and beneficial effects of the above technical solution are:

[0108] When the box body 17 moves outward with the telescopic arm 13, the negative pressure box 30 is driven to move through the cross bar 23, so that the distance between the first wire wheel 35 and the second wire wheel 36 increases, and the second wire wheel 36 is locked and does not rotate. As the connecting line 37 is extended, the first wire wheel 35 is pulled to rotate, so that the screw 34 rotates accordingly. The screw 34 is threadedly connected to the piston plate 33, driving the piston plate 33 to move upward in the negative pressure box 30, and the lower space of the negative pressure box 30 is increased, and negative pressure is generated at the lower part of the box body 17. The auxiliary support platform 18 moves downward, so that the sprinkler head 3 is better stored in the box body 17, reducing the squeezing of the sprinkler head 3 by the cover plate 22, and avoiding the sprinkler head from accidentally popping out during the storage process; when the box body 17 moves inward with the telescopic arm 13, the screw 34 rotates in the opposite direction and resets under the action of the coil spring, rewinds the connecting line 37, and the piston plate 33 moves downward, and the air pressure in the lower part of the box body 17 is restored. A handle 38 is provided on the second wire wheel 36. When a failure occurs in the movement of the support platform 18, the second wire wheel 36 can be manually unlocked to debug the negative pressure assembly for easy maintenance.

When cleaning, the first cleaning surface 43 contacts the inner wall of the water tank 1. The second cleaning surface 44 is provided with a first inner concave surface 45 and a second inner concave surface 46. The second inner concave surface 46 is arranged close to the roller shaft 41.

[0113] The telescopic arm 13 may be provided with a motor for driving the roller shaft 41 to rotate.

[0114] The working principle and beneficial effects of the above technical solution are:

[0115] A plurality of evenly arranged cleaning plate groups are arranged on the cleaning roller 4, and the cleaning plates 42 are arranged in an alternating manner. On the one hand, when the cleaning liquid is sprayed, it can flow through the gaps between the adjacent cleaning plates 42, so that the cleaning effect on the cleaning roller 4 is better; on the other hand, large particles of attached matter can be cut off when passing between the adjacent cleaning plates 42, and can be better carried by the cleaning liquid and fall after rinsing. The first cleaning surface 43 of the cleaning plate 42 is set to an arc shape, which is convenient for the contact and rotation between the cleaning roller 4 and the inner wall of the water tank 1, and the two are more fitted, so that the cleaning effect is better. The second cleaning surface 44 of the cleaning plate 42 is provided with two concave surfaces, and a sharp angle is formed between the first inner concave surface 45 and the first cleaning surface 43, so as to reduce the attachment of the attached matter on the second cleaning surface 44 after cleaning, so that it can fall better; the second inner concave surface 45 is close to the roller shaft 41, and when the attached matter accumulates and approaches the roller shaft 41 after being cleaned, a buffer space is formed by the second inner concave surface 45 to avoid direct accumulation on the roller shaft 41, affecting the transmission of the roller shaft 41, and improving the transmission effectiveness of the roller shaft 41. During cleaning, the inner wall of the water tank 1 contacts at least two cleaning plate groups, so that the cleaning process is uninterrupted. The telescopic arm 13 may be provided with a motor for driving the roller shaft 41 to rotate, and the motor actively drives the roller shaft 41 to rotate, thereby improving the cleaning effect of the cleaning roller 4 on stubborn attachments.
