Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1 - 6 as shown, it includes a support plate 2. An electric motor clamping structure is provided on the support plate 2. The support plate 2 is movably installed above the fermentation tank 1 through the electric motor clamping structure. An lifting plate 16 is installed below the support plate 2 through a lifting assembly. A water spraying structure is provided inside the lifting plate 16. An adaptive cleaning assembly is provided below the lifting plate 16;

[0028] The motorized clamping structure includes a clamping motor 6 disposed above the support disk 2. A clamping gear 7 is rotatably installed vertically within the support disk 2. The rotating shaft of the clamping motor 6 is connected to the clamping gear 7. The clamping gear 7 is drivingly connected to a first synchronization assembly and a second synchronization assembly disposed within the support disk 2. The first synchronization assembly is located directly above the second synchronization assembly. The first synchronization assembly is connected to two clamping drive rods 3 slidably installed within the support disk 2. The second synchronization assembly is connected to two clamping drive rods 4 slidably installed within the support disk 2. The outer bottom ends of the clamping drive rods 3 and the clamping drive rods 4 are both connected to clamping heads 14. The bottom end of each clamping head 14 is provided with a clamping groove 15 facing inwards. The heights of the clamping grooves 15 of several clamping heads 14 are flush.

[0029] The first synchronization assembly includes a first activity groove 10 opened within the support disk 2. On both sides of the clamping gear 7 within the first activity groove 10, two clamping racks 8 are respectively movably provided. Both of the two clamping racks 8 are engaged with the clamping gear 7. One end of each clamping rack 8 is connected to a clamping drive rod 3 through a first connecting member 9.

[0030] The second synchronization assembly includes a second activity groove 11 opened within the support disk 2. On both sides of the clamping gear 7 within the second activity groove 11, two clamping racks 12 are respectively movably provided. Both of the two clamping racks 12 are engaged with the clamping gear 7. One end of each clamping rack 12 is connected to a clamping drive rod 4 through a second connecting member 13.

[0031] As an optimized solution of the present utility model, the clamping motor 6 is set to drive the clamping gear 7 to rotate. Then, the clamping gear 7 drives the two clamping racks 12 to move inwards or outwards synchronously. Thus, the two clamping drive rods 4 are driven to move synchronously through the second connecting member 13. At the same time, the clamping gear 7 drives the two clamping drive rods 3 to move in the same manner. Thereby, it is ensured that several clamping heads 14 move synchronously. Thus, the edge of the fermentation tank 1 can be clamped by the clamping heads 14, and then the device is clamped onto the fermentation tank 1. At the same time, the moving distances of the clamping drive rods 3 and the clamping drive rods 4 are the same, ensuring that the support disk 2 is located at the central position.

[0032] See Figures 1 - 3 As shown, the lifting assembly includes several lifting electric cylinders 17 disposed above the support disk 2. All of the several lifting electric cylinders 17 are arranged downward. The telescopic rods of the lifting electric cylinders 17 movably penetrate through the support disk 2 and are then connected to a lifting disk 16.

[0033] As an optimized solution of the present utility model, the lifting disk 16 is driven to move up and down by the lifting electric cylinders 17.

[0034] See Figures 1 - 3As shown in the figure, the water spraying structure includes several water spray heads 20 arranged at the outer edge of the lifting disc 16. The several water spray heads 20 are evenly arranged along the circumference of the lifting disc 16. A water inlet pipe 18 is installed on the support disc 2. The water inlet pipe 18 is connected to an external water supply device. A telescopic pipe 19 is arranged between the support disc 2 and the lifting disc 16. The water inlet pipe 18 passes through the support disc 2 and is connected to one end of the telescopic pipe 19. The other end of the telescopic pipe 19 is connected to the several water spray heads 20 through a pipeline inside the lifting disc 16.

[0035] As an optimized solution of the present utility model, water is sent into the water spray heads 20 through the water inlet pipe 18 and the telescopic pipe 19 for spraying, so as to wash the inner wall of the fermentation tank 1 with water. At the same time, the telescopic pipe 19 can automatically stretch and contract with the lifting of the lifting disc 16, without manual pipe maintenance.

[0036] See Figures 1 - 7 As shown in the figure, the adaptive cleaning component includes a rotary motor 21 arranged on the lifting disc 16. The rotating shaft of the rotary motor 21 passes through the lifting disc 16 movably and is connected with a rotating disc 22. Several movable support rods 23 are inserted on the outer side of the rotating disc 22. A cleaning brush 24 is connected to the outer end of each movable support rod 23. The movable support rod 23 is slidably arranged in the rotating disc 22. A chute 25 is opened in the rotating disc 22. A slider 26 is arranged on the movable support rod 23. The slider 26 is slidably arranged in the chute 25, and a spring 27 is arranged between the slider 26 and the inner wall of the chute 25.

[0037] As an optimized solution of the present utility model, when the movable support rod 23 and the slider 26 are pushed inward, the spring 27 will be compressed. Then the spring 27 will push the movable support rod 23 and the cleaning brush 24 outward in the reverse direction, so that the cleaning brush 24 is closely attached to the inner wall of the fermentation tank 1, and the cleaning brush 24 is driven to rotate by the rotary motor 21 to clean the fermentation tank 1.

[0038] See Figures 1 - 6 As shown in the figure, guide strips 5 are arranged on the sides of the clamping drive rod one 3 and the clamping drive rod two 4.

[0039] As an optimized solution of the present utility model, the guide strips 5 are arranged to enhance the sliding stability of the clamping drive rod one 3 and the clamping drive rod two 4.

[0040] The usage process of the present utility model:

[0041] First, lift this device, and then move the device above the fermenter 1 that needs to be cleaned. Start the clamping motor 6 to drive several chucks 14 to move outward simultaneously to the outside of the fermenter 1. Then lower this device, and push the movable support rod 23 inward to make the cleaning brush 24 enter the fermenter 1. The spring 27 presses the cleaning brush 24 against the inner wall of the fermenter 1. Then lower the device until the height of the clamping groove 15 is flush with the top surface of the fermenter 1. Then reverse-start the clamping motor 6 to drive several chucks 14 to retract synchronously and clamp to the edge of the fermenter 1 to complete the fixation;

[0042] Then connect the water inlet pipe 18 to the water supply pipeline, start the water supply, and the spray head 20 starts to spray water. Start the rotating motor 21, and the rotating motor 21 drives the rotating disk 22 and several cleaning brushes 24 to rotate to brush the sundries on the inner wall of the fermenter 1. The lifting electric cylinder 17 drives the device below to gradually move downward. During the movement, the water flow sprayed by the spray head 20 flows downward to lubricate the cleaning brush 24, and at the same time wet the inner wall of the fermenter 1 to enhance the cleaning effect. And the water flow flushes the position brushed by the cleaning brush 24 for a second time to enhance the cleaning effect. At the same time, when it is found that a local area is not cleaned thoroughly, the lifting electric cylinder 17 can be controlled to drive the cleaning brush 24 to rise to clean the specified position again;

[0043] After the cleaning is completed, start the clamping motor 6 and push the chucks 14 outward to remove this device.
