[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This example 1 provides a microbial fermentation tank cleaning device with a unique structure. Figure 1-4As shown, it includes a fixed plate 1, and a lifting mechanism 2 is fixedly installed at both ends of the fixed plate 1. The lower end of the lifting mechanism 2 is fixedly connected to the ground, and the lifting mechanism 2 is electrically connected to an external power supply. There are many options for the lifting mechanism 2, for example: a multi-stage electric lifting rod, through which the lifting range of the fixed plate 1 can be greatly increased, so that fermentation tanks at different heights can be cleaned; it also includes a variable diameter cleaning device, which includes a driving motor 3, a driving shaft 4 vertically rotatably installed on the fixed plate 1 and transmission-connected to the driving motor 3, and a variable diameter cleaning mechanism arranged at the lower end of the driving shaft 4; there are many ways to install the driving shaft 4, for example: the driving motor 3 is fixedly installed on the top of the fixed plate 1, a through hole is opened on the fixed plate 1, the driving shaft 4 is rotatably installed in the through hole through a bearing, and the upper end of the driving shaft 4 passes through the through hole and is fixedly connected to the output shaft of the driving motor 3.

[0017] A cavity is provided inside the drive shaft 4, and a partition is fixedly installed in the middle of the cavity, which divides the cavity into two chambers, an upper chamber and an lower chamber. A fixed cylinder 14 is rotatably mounted on the drive shaft 4 at the upper part of the upper chamber, and a power supply is fixedly installed in the lower chamber; the top of the fixed cylinder 14 is fixedly connected to the fixed plate 1, and an annular cavity is concentrically provided in the middle, and a water inlet pipe communicating with the annular cavity is fixedly installed on the fixed cylinder 14, and a water inlet communicating with the upper chamber is provided on the drive shaft 4 in the annular cavity. There are many ways to fix the fixed cylinder 14 to the fixed plate 1, for example: L-shaped fixing rods 13 are symmetrically fixedly installed on both sides of the fixed cylinder 14, and the other end of the fixing rod 13 is fixedly connected to the fixed plate 1, and the water inlet pipe is connected to a high-pressure water delivery device, for example: a high-pressure water pump, which injects high-pressure water into the upper chamber through the high-pressure water pump; the variable diameter cleaning mechanism includes a push-out assembly, a sleeve 9 slidably mounted on the drive shaft 4, and a plurality of vertically arranged nozzles 5 evenly arranged on the circumference of the drive shaft 4, and the sleeve 9 is fixedly connected to the output end of the push-out assembly.

[0018] The ejection assembly includes a support plate 8 fixedly mounted on the drive shaft 4, and also includes a plurality of wireless electric push rods 10 fixedly mounted on the bottom of the support plate 8 along the circumference. The lower end of the wireless electric push rod 10 is fixedly connected to the sleeve 9, and the wireless electric push rod 10 is electrically connected to the power supply. The extension and contraction of the wireless electric push rod 10 is remotely controlled by a remote control, thereby driving the sleeve 9 to move up and down along the drive shaft 4; two parallel connecting rods 6 are provided between the nozzle 5 and the drive shaft 4, and the two ends of the connecting rod 6 are respectively hinged to the drive shaft 4 and the nozzle 5, and the upper side of the nozzle 5 close to the drive shaft 4 is hinged with a pull rod. Rod 7, the other end of the pull rod 7 is hinged with the sleeve 9; the bottom end of the nozzle 5 is sealed, and a water pipe 11 is fixedly installed on the upper end. The other end of the water pipe 11 is connected to the bottom of the upper chamber. A plurality of nozzle groups are arranged at intervals along the axial direction on the nozzle 5. The nozzle group includes a plurality of high-pressure nozzles 12 fixedly installed on the nozzle 5 evenly along the circumference, and the high-pressure nozzles 12 in the upper section of the nozzle 5 are inclined upward, and the high-pressure nozzles 12 in the lower section are inclined downward. By arranging the high-pressure nozzles 12 inclined upward and downward on the nozzle 5, the inner bottom surface, inner side surface and inner top surface of the fermentation tank can be cleaned.

[0019] In the initial state, the multiple nozzles 5 are retracted. When using the cleaning device to clean a fermenter, the fermenter is first moved below the variable-diameter cleaning device. The lifting mechanism 2 is then controlled to retract, allowing the retracted variable-diameter cleaning device to be inserted into the fermenter through the tank opening. When the device reaches a certain depth, the output end of the wireless electric push rod 10 is extended via a remote control, causing the sleeve 9 to slide downward along the drive shaft 4. As the sleeve 9 slides downward, the multiple nozzles 5 are simultaneously expanded outward, bringing the nozzles 5 into close contact with the side wall of the fermenter. The drive motor 3 and the high-pressure water supply device are then simultaneously activated. The drive motor 3 rotates the drive shaft 4, driving the multiple nozzles 5 in rotation. Simultaneously, the high-pressure water supply device pumps pressurized water from an external source into the annular cavity of the fixed cylinder 14. The water is then delivered to each nozzle 5 through the upper chamber of the drive shaft 4. Finally, the water is sprayed out from each high-pressure nozzle 12, thereby cleaning the inner bottom, inner side, and inner top surfaces of the fermenter, improving the cleaning effect.

[0020] Example 2: The difference between Example 2 and Example 1 is that infrared sensors are fixedly installed on the lower end of the drive shaft 4 and the top of the support plate 8 for monitoring the distance between the variable diameter cleaning mechanism and the upper and lower ends of the fermentation tank. Wireless cameras and lighting lamps are fixedly installed at intervals on the drive shaft 4 between any two adjacent nozzles 5. The sensors, cameras and lighting lamps are all electrically connected to the power supply. Through the coordinated setting of the wireless camera and the lighting lamp, the stains inside the fermentation tank can be directly observed and fixed-point cleaning can be performed, thereby achieving better cleaning effects.
