[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a raw water storage tank with an easily cleanable inner wall, comprising a tank body 1. The tank body 1 has a rotatably connected stirring and cleaning assembly 2 inside. The stirring and cleaning assembly 2 includes a vertically arranged stirring shaft 201. Screws 202 are symmetrically arranged on the upper and lower sides of the outer wall of the stirring shaft 201. A screw nut 203 is movably fitted onto the outer wall of the screw nut 202. A cleaning ring 205 is provided outside the screw nut 203 in the stirring and cleaning assembly 2. Several support rods 204 are horizontally arranged between the outer wall of the screw nut 203 and the cleaning ring 205. The outer wall of the cleaning ring 205 is in contact with the inner wall of the tank body 1. Several sliders 206 are vertically arranged on the outer wall of the cleaning ring 205. A groove matching the sliders 206 is vertically arranged on the inner wall of the tank body 1. The outer wall of the stirring shaft 201 is horizontally provided with several first stirring rods 207 at the top. The first stirring rod 207 is provided with a first support block 208 at the end away from the stirring shaft 201. The bottom of the first support block 208 is provided with a first cleaning brush 209. The outer wall of the stirring shaft 201 is horizontally provided with several second stirring rods 210 at the bottom. The second stirring rod 210 is provided with a second support block 211 at the end away from the stirring shaft 201. The top of the second support block 211 is provided with a second cleaning brush 212. The outer wall of the stirring shaft 201 is horizontally provided with several third stirring rods 213 between two lead screws 202. The third stirring rod 213 is provided with a third support block 214 at the end away from the stirring shaft 201. The top and bottom of the third support block 214 are provided with third cleaning brushes 215.

[0023] In one embodiment, the two lead screw nuts 203 are arranged vertically and parallel to each other. Since the two lead screws 202 are arranged vertically and symmetrically, the two lead screw nuts 203 are now arranged in parallel with the same orientation. This allows the two lead screw nuts 203 to move in different directions when the two lead screws 202 rotate synchronously. The two lead screw nuts 203 can move simultaneously toward the center of the stirring shaft 201 or simultaneously toward both ends of the stirring shaft 201, thereby driving the two cleaning rings 205 to move simultaneously toward the center of the tank body 1 or simultaneously toward the upper and lower ends of the tank body 1.

[0024] In one embodiment, a servo motor 101 is provided on the top of the outer wall of the storage tank body 1. The output shaft of the servo motor 101 is fixedly connected to the top of the stirring shaft 201 through a reducer 102. The servo motor 101 drives the stirring shaft 201 to rotate through the reducer 102, thereby driving the stirring and cleaning assembly 2 to perform stirring and cleaning work. A water inlet pipe 103 is provided on one side of the top of the outer wall of the storage tank body 1, and a drain pipe 104 is provided at the center of the bottom of the storage tank body 1. The water inlet pipe 103 is used to transport raw water into the storage tank body 1, and the drain pipe 104 is used to discharge raw water from the storage tank body 1.

[0025] The working principle of this utility model:

[0026] Refer to the instruction manual appendix Figures 1-4 This utility model comprises a storage tank body 1, a stirring and cleaning assembly 2, a stirring shaft 201, a lead screw 202, a lead screw nut 203, and a cleaning ring 205. The storage tank body 1 is used to store raw water, the stirring and cleaning assembly 2 is used to stir and clean the inside of the storage tank body 1, and the support rod 204 supports the lead screw nut 203 and the cleaning ring 205 to ensure that the cleaning ring 205 moves with the lead screw nut 203.

[0027] When the stirring and cleaning assembly 2 is working, the stirring shaft 201 rotates, and the lead screw 202 rotates with the stirring shaft 201. The lead screw 202 works in conjunction with the lead screw nut 203, which can drive the lead screw nut 203 to move up and down. The lead screw nut 203 drives the cleaning ring 205 to move up and down through the support rod 204. During the up and down movement of the cleaning ring 205, the inner wall of the storage tank body 1 can be cleaned. It can effectively clean the inner wall of the storage tank body 1, and the cleaning mechanism is relatively simple. It will not create cleaning dead corners due to its own structure, thereby reducing the possibility of the raw water stored inside the storage tank body 1 being contaminated. The cooperation design of the slider 206 and the chute guides the cleaning ring 205 in the vertical direction on the outer wall of the cleaning ring 205. It can effectively limit the cleaning ring 205 in the vertical direction, so that the cleaning ring 205 can only move up and down. This ensures that the lead screw nut 203 moves up and down normally along the lead screw 202, thereby ensuring the normal cleaning of the storage tank body 1.

[0028] During the rotation of the stirring shaft 201, the first stirring rod 207 rotates at the top of the stirring shaft 201, and the first support block 208 rotates with the first stirring rod 207, so that the first support block 208 and the first cleaning brush 209 move in a circle around the stirring shaft 201. When the cleaning ring 205 located above moves to the bottom of the first cleaning brush 209, the first cleaning brush 209 cleans the top of the cleaning ring 205.

[0029] During the rotation of the stirring shaft 201, the second stirring rod 210 rotates at the bottom of the stirring shaft 201, and the second support block 211 rotates with the second stirring rod 210, causing the second support block 211 and the second cleaning brush 212 to move in a circle around the stirring shaft 201. When the cleaning ring 205 located below moves to the top of the second cleaning brush 212, the second cleaning brush 212 cleans the bottom of the cleaning ring 205.

[0030] During the rotation of the stirring shaft 201, the third stirring rod 213 rotates in the middle of the stirring shaft 201, and the third support block 214 rotates with the third stirring rod 213, causing the third support block 214 and the third cleaning brushes 215 at its top and bottom to move in a circular motion around the stirring shaft 201. When the upper cleaning ring 205 moves to the top of the third support block 214, the third cleaning brush 215 at the top of the third support block 214 cleans the bottom of the cleaning ring 205. When the lower cleaning ring 205 moves to the bottom of the third support block 214, the third cleaning brush 215 at the bottom of the third support block 214 cleans the top of the cleaning ring 205.

[0031] The design of the stirring rod, support block and cleaning brush can clean the surface of the cleaning ring 205 while stirring the raw water inside the storage tank body 1, making the operation convenient and quick.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
