The rotation mechanism 230... 30 and mounting bracket 240 are slidably sleeved on the lower end of drive mechanism 210. Rotating nozzle mechanism 250 is rotatably connected to the lower end of mounting bracket 240. The output end of rotating mechanism 230 drives rotating nozzle mechanism 250 to rotate. Liquid supply mechanism 260 is connected to rotating nozzle mechanism 250 through the lower end of mounting bracket 240. The lower end of liquid supply mechanism 260 can rotate with mounting bracket 240. The upper end of liquid supply mechanism 260 slides through the interior of rotating mechanism 230 and passes through the upper end of drive mechanism 210. The upper end of drive mechanism 210 restricts the rotation of upper end of liquid supply mechanism 260. Drive mechanism 210 drives mounting bracket 240 to revolve around the central axis of drive mechanism 210. Drive mechanism 210 drives rotating mechanism 230 to rotate. An opening is made in the existing water storage facility 100 so that the lower end of the automatic cleaning system 200 extends into the water storage facility 100. The top end of the drive mechanism 210 is sealed and installed on the top end of the water storage facility 100 by bolts. The installation is simple and convenient to install on the existing water storage facility 100.When using the automatic cleaning system 200, the drive mechanism 210 is activated. The drive mechanism 210 drives the rotation mechanism 230 and the mounting bracket 240 to revolve around the central axis of the drive mechanism 210. The rotating nozzle mechanism 250 revolves with the mounting bracket 240, achieving 360° rinsing in the horizontal plane. Simultaneously, the drive mechanism 210 drives the rotation mechanism 230 to rotate, which in turn drives the rotating nozzle mechanism 250 to rotate. The rotating nozzle mechanism 250 rotates around its own central axis, achieving 360° rinsing in the vertical plane. The height adjustment mechanism 220 is activated, causing the height position of the rotation mechanism 230 and the mounting bracket 240 to change, adjusting the rotating nozzle mechanism 250 to the water storage facility. The positions of the top and bottom of the water storage facility 100 are designed to allow the rotating nozzle mechanism 250 to maintain impact pressure for cleaning the top and bottom of the water storage facility 100. The rotating nozzle mechanism 250 is driven by the drive mechanism 210 to achieve revolution and rotation, thus achieving all-round cleaning of the water storage facility 100. The height adjustment mechanism 220 adjusts the position of the rotating nozzle mechanism 250 from the top and bottom of the water storage facility 100, ensuring that the rotating nozzle mechanism 250 can maintain sufficient rinsing force for cleaning the top and bottom of the water storage facility 100, thereby improving the cleaning effect of the rotating nozzle mechanism 250 on the water storage facility 100. Furthermore, adjacent automatic cleaning systems 200 can also rinse and clean each other, reducing residual pollution.

[0033] Please see Figures 1 to 3The drive mechanism 210 includes a mounting cylinder 211, a drive motor 212, a sun gear structure 213, a revolution cylinder 214, a rotation rod 215, and a support tube 216.

The follower ring 223 is concentric with the rotation axis of the self-rotating rod 215. The drive rod 221 is fixedly connected to the upper side of the mounting plate 2111, and the output rod of the drive rod 221 passes through the mounting plate 2111 and the isolation cylinder 2114 in sequence to reduce the possibility of short circuit due to contact with liquid. It should be noted that in this embodiment, the drive rod 221 is set as an electric push rod. When the support pipe 216 drives the mounting bracket 240 and the rotating nozzle mechanism 250 to revolve around the central axis of the revolving cylinder 214, the follower ring 223 rotates within the force-applying ring 222 along with the mounting bracket 240. Activating the drive rod 221 causes the force-applying ring 222 to move up and down. The force-applying ring 222 then drives the follower ring 223, which in turn changes the height of the rotating mechanism 230 and the mounting bracket 240, thereby changing the height of the rotating nozzle mechanism 250. This adjusts the distance between the rotating nozzle mechanism 250 and the top and bottom of the water storage facility 100, ensuring sufficient rinsing force for cleaning the top and bottom of the water storage facility 100. The force-applying ring 222 includes a ring body 2221 and a connecting block 2222, which is fixedly connected to the outside of the ring body 2221.

The worm wheel 233 is fixedly sleeved on the self-rotating nozzle mechanism 250. The worm gear 232 and the worm wheel 233 mesh with each other. The pressing cover 234 is fixedly sleeved on the bottom end of the worm gear 232. The liquid supply mechanism 260 is rotatably connected to the interior of the bottom end of the worm gear 232. The pressing cover 234 presses the position where the liquid supply mechanism 260 is rotatably connected to the worm gear 232 into the worm gear 232. The upper end of the self-rotating hollow rod 231 rotates through the follower ring 223 via a bearing, and the rhomboid hollow rod 2153 is slidably inserted into the interior of the self-rotating hollow rod 231. The rhomboid hollow rod 2153 engages with the rhomboid hollow interior of the self-rotating hollow rod 231, causing the rhomboid hollow rod 2153 to drive the self-rotating hollow rod 231 to rotate, and also allowing the self-rotating hollow rod 231 to slide up and down along the rhomboid hollow rod 2153. The self-rotating hollow rod 231 rotates with the rhomboid hollow rod 2153, which in turn drives the worm gear 232 to rotate. The worm gear 232 drives the worm wheel 233 to rotate through the worm gear meshing principle, and the worm wheel 233 drives the self-rotating nozzle mechanism 250 to rotate, enabling the self-rotating nozzle mechanism 250 to perform 360° rinsing in the vertical plane.

[0039] Please see Figures 1 to 7 The mounting bracket 240 includes a limiting tube 241, a mounting base 242, a connecting rod 243, a water supply connection seat 244, and a connecting steel pipe 245. The mounting base 242 is fixedly connected to the bottom end of the limiting tube 241, and the upper end of the limiting tube 241 is fixedly inserted through the lower end of the height adjustment mechanism 220. Connecting rods 243 are fixedly connected to both ends of the mounting base 242. Two water supply connection seats 244 are provided, each fixedly connected to the end of the connecting rod 243. The two ends of the self-rotating nozzle mechanism 250 are rotatably connected between the two water supply connection seats 244. The connecting steel pipe 245 is fixedly connected inside the water supply connection seat 244, and the liquid supply mechanism 260 is connected to the connecting steel pipe 245. A follower ring 223 is fixedly inserted through the upper end of the limiting tube 241. A support tube 216 is slidably inserted into the limiting tube 241. The support pipe 216, via the limiting pipe 241, actuates the follower ring 223 to rotate within the force-applying ring 222. The follower ring 223, via the limiting pipe 241, causes the mounting base 242, the water supply connection seat 244, and the self-rotating sprinkler mechanism 250 to change their vertical positions. The connecting rod 243 is fixedly connected to the mounting base 242 and the water supply connection seat 244 at both ends via threads or bolts. When the self-rotating sprinkler mechanism 250 needs to be replaced or repaired, the connecting rod 243 is removed, allowing the water supply connection seat 244 and the self-rotating sprinkler mechanism 250 to be removed for replacement or repair. The cleaning fluid flows into the self-rotating sprinkler mechanism 250 through the connecting steel pipe 245 and the water supply connection seat 244.

[0040] Please see Figures 1 to 8 The rotating nozzle mechanism 250 includes a rotating pipe seat 251, a nozzle 253, a first rotary joint 254, and a limiting sleeve 255. The rotating pipe seat 251 has a liquid supply channel 252 inside. The nozzle 253 is mounted on the rotating pipe seat 251 and connected to the liquid supply channel 252. First rotary joints 254 are provided at both ends of the rotating pipe seat 251. The liquid supply mechanism 260 supplies liquid to the liquid supply channel 252 through the first rotary joints 254. The limiting sleeve 255 is fixedly connected to both ends of the rotating pipe seat 251 and rotatably connected to the mounting bracket 240. Two water supply connecting seats 244 have rotating grooves 246 on opposite sides. A worm gear 233 is fixedly sleeved on the rotating pipe seat 251. The cleaning fluid flows to the supply channel 252 through the connecting steel pipe 245, the water supply connector 244, and the first rotary joint 254. The cleaning fluid in the supply channel 252 is sprayed out through the nozzle 253. When the self-rotating pipe seat 251 rotates, the limiting sleeve 255 rotates in the rotating groove 246. The rotating groove 246 restricts the position of the limiting sleeve 255, thereby restricting the rotation of the self-rotating pipe seat 251, reducing the radial force on the first rotary joint 254, and thus reducing the damage to the first rotary joint 254. At the same time, the first rotary joint 254 rotates with the self-rotating pipe seat 251 through its own rotation.

[0041] Please see Figures 1 to 9The liquid supply mechanism 260 includes a water supply steel pipe 261, limiting strips 262, a pressure ring 263, a thrust ball bearing 264, a second rotary joint 265, and a tee steel pipe 266. The limiting strips 262 are evenly spaced on the upper end of the water supply steel pipe 261. The upper end of the water supply steel pipe 261 and the limiting strips 262 slide through the upper end of the drive mechanism 210. The drive mechanism 210 restricts the rotation of the water supply steel pipe 261 through the limiting strips 262. The pressure ring 263 is fixedly sleeved on the water supply steel pipe 261. At the lower end of 61, two thrust ball bearings 264 are fitted onto the lower end of the water supply steel pipe 261. The two thrust ball bearings 264 are located on both sides of the pressure ring 263. The bottom end of the self-rotating mechanism 230 presses the thrust ball bearings 264 on the lower side of the pressure ring 263. The bottom end of the water supply steel pipe 261 is connected to the inlet of the tee steel pipe 266 through the second rotary joint 265. The two outlets of the tee steel pipe 266 are connected to the two ends of the self-rotating nozzle mechanism 250 through the lower end of the mounting bracket 240. The rotary joints used by the first rotary joint 254 and the second rotary joint 265 are precision connection devices for transmitting fluid between pipelines and rotating equipment. Their principle is clear to those skilled in the art and will not be described in detail here. The upper end of the water supply steel pipe 261 and the limiting strip 262 slide through the limiting frame 2113, which restricts the rotation of the water supply steel pipe 261. The clamping cover 234 presses the two thrust ball bearings 264 and the pressure ring 263 tightly inside the bottom of the worm gear 232. The water supply steel pipe 261 is rotatably connected to the worm gear 232 through the thrust ball bearings 264 on both sides of the pressure ring 263. When the self-rotating sprinkler head mechanism 250 revolves, it drives the three-way steel pipe 266 to rotate around the water supply steel pipe 261 through the second rotary joint 265. When the height adjustment mechanism 220 drives the self-rotating sprinkler head mechanism 250 to move up and down, the self-rotating mechanism 230 applies force to the pressure ring 263 through the clamping cover 234 and the worm gear 232, causing the water supply steel pipe 261 to slide along the limiting frame 2113. The cleaning fluid is supplied to the tee pipe 266 through the water supply steel pipe 261 and the second rotary joint 265, and the cleaning fluid is supplied to the self-rotating nozzle mechanism 250 through the tee pipe 266 and the mounting bracket 240.

[0042] Specifically, the working principle of the automatic cleaning equipment for the secondary water supply tank and tank body is as follows: During installation, a hole is made in the existing water storage facility 100, and the components on the lower side of the mounting plate 2111 extend into the water storage facility 100. The mounting plate 2111 is installed on the top of the water storage facility 100 by bolt sealing. The installation is simple and convenient to install on the existing water storage facility 100.

[0043] In use, the drive motor 212 is started, which drives the drive gear 2133. The drive gear 2133 drives the inner ring gear 2131 and the inner gear outer ring 2132 to rotate in opposite directions through the gear meshing principle. The inner gear outer ring 2132 drives the revolution cylinder 214 to rotate inside the mounting cylinder 2112. The revolution cylinder 214 drives the support tube 216 to revolve around the central axis of the revolution cylinder 214. The support tube 216 moves the follower ring 223 to rotate inside the force ring 222 through the limit tube 241. The mounting base 242, the water supply connection base 244, and the self-rotating nozzle mechanism 250 revolve around the central axis of the revolution cylinder 214 with the limit tube 241. During this process, the water supply connection base 244 drives the three-way steel pipe 266 to rotate around the water supply steel pipe 261 through the second rotary joint 265, so that the nozzle 253 can rinse 360° in the horizontal plane.

[0044] Simultaneously, the inner ring gear 2131 drives the rotating tube 2151 to rotate around its central axis. The rhomboid hollow rod 2153 rotates with the rotating tube 2151. The rhomboid hollow rod 2153 engages with the rhomboid hollow interior of the rotating hollow rod 231, causing the rhomboid hollow rod 2153 to drive the rotating hollow rod 231 to rotate within the follower ring 223. The rotating hollow rod 231 drives the worm 232 to rotate. The worm 232 drives the worm wheel 233 to rotate through the worm gear meshing principle. The worm wheel 233 drives the rotating tube seat 2151 to rotate. 51 rotates around its own central axis. At this time, the limiting sleeve 255 rotates in the rotating groove 246. The rotating groove 246 restricts the position of the limiting sleeve 255, thereby restricting the rotation of the self-rotating tube seat 251, reducing the radial force on the first rotating joint 254, and thus reducing the damage to the first rotating joint 254. At the same time, the first rotating joint 254 rotates with the self-rotating tube seat 251 through its own rotation. The self-rotating tube seat 251 drives the nozzle 253, realizing 360° rinsing of the nozzle 253 in the vertical plane.

[0045] The drive rod 221 is activated, which drives the force ring 222 to move up and down. The force ring 222 drives the follower ring 223, which in turn drives the rotating hollow rod 231 and the limiting tube 241 to move up and down. The rotating hollow rod 231 slides along the prismatic hollow rod 2153. At the same time, the limiting tube 241 slides along the support tube 216. The limiting tube 241 drives the mounting base 242, the water supply connection base 244, and the nozzle 253 to change their up and down positions, thereby adjusting the distance between the nozzle 253 and the top and bottom of the water storage facility 100. This ensures that the nozzle 253 can maintain sufficient rinsing force for cleaning the top and bottom of the water storage facility 100. During this process, the pressure cap 234 and the worm gear 232 apply force to the pressure ring 263, which drives the water supply steel pipe 261 to slide along the limiting frame 2113.

[0046] The drive motor 212 drives the sun gear structure 213 to realize the revolution and rotation of the nozzle 253, thereby achieving all-round cleaning within the water storage facility 100. The height adjustment mechanism 220 adjusts the position of the nozzle 253 from the top and bottom of the water storage facility 100, so that the nozzle 253 can maintain sufficient rinsing force for cleaning the top and bottom of the water storage facility 100, improving the cleaning effect of the nozzle 253 on the water storage facility 100. Adjacent automatic cleaning systems 200 can also rinse and clean each other, reducing pollution residue. The height adjustment mechanism 220 adapts the rotation of the rotating hollow rod 231 and the limit tube 241 through the setting of the force ring 222 and the follower ring 223, so that the revolution, rotation and height adjustment of the nozzle 253 cooperate with each other without affecting each other.

[0047] During the cleaning process, the cleaning fluid flows through the water supply steel pipe 261 and the second rotary joint 265 to the three-way steel pipe 266, and then through the three-way steel pipe 266 to the connecting steel pipe 245. After that, the cleaning fluid flows through the water supply connecting seat 244 and the first rotary joint 254 to the liquid supply channel 252, and the cleaning fluid in the liquid supply channel 252 is sprayed out through the nozzle 253.
