The adjusting seat 5 is equipped with a locking and limiting structure adapted to the rotating seat 3, and the control box 2 is equipped with an engaging unit adapted to the first gear 6. By driving the control box 2 to move downward through the moving member, the cleaning roller 8 is inserted into the corresponding container. By driving the plurality of first connecting shafts 12 to rotate synchronously through the synchronous driving mechanism, the first connecting shaft 12 drives the second rotating shaft 7 and the cleaning roller 8 to rotate synchronously through the rotating seat 3 and the adjusting seat 5, so that the cleaning roller 8 moves along the inner wall of the container. At the same time, the engaging unit drives the first gear 6 to rotate self, and the first gear 6 drives the second rotating shaft 7 and the cleaning roller 8 to rotate self through the second gear 11, changing the position where the cleaning roller 8 contacts the container, so that different positions on the cleaning roller 8 clean the inner wall of the container, facilitating the cleaning of the inner wall of the container and ensuring that the inner wall of the container can be cleaned cleanly, avoiding affecting the experimental results of the next time.

A fixed disk 17 is fixedly connected to the bottom end of the movable column 15, and the top of the fixed disk 17 and the bottom of the first support portion 16 are connected by a tension spring 18;

[0038] When the synchronous drive mechanism drives a plurality of first connecting shafts 12 to rotate synchronously, the first connecting shafts 12 drive the first gear 6 to roll on the gear ring 9 through the rotating base 3 and the first rotating shaft 4, so that the first gear 6 rotates on its own axis. The staff drives the first arc-shaped rack 13 and the movable column 15 to move downward, so that the first arc-shaped rack 13 no longer meshes with the second arc-shaped rack 14. The movable column 15 drives the fixed disk 17 to move downward, and the tension spring 18 is in a stretched state. The staff drives the adjusting base 5 to rotate relative to the first rotating shaft 4. When the adjusting base 5 rotates to a preset position, the staff releases the first arc-shaped rack 13 and the movable column 15, and the tension spring 18 drives the fixed disk 17 and the movable column 15 to move upward, so that the first arc-shaped rack 13 meshes with the second arc-shaped rack 14, and the adjusting base 5 can be fixed relative to the rotating base 3.

[0039] Embodiment 3, based on Embodiment 1, by Figure 1 、 Figure 2 and Figure 3Given that the container positioning structure includes several support frames 19 fixedly installed on the inner bottom wall of the cleaning tank 1, the bottom of the cleaning tank 1 is fixedly connected to a base 20. Clamping plates 22 are respectively provided on both sides of the support frame 19. Movable frames 21 are respectively fixedly connected to the sides of adjacent two clamping plates 22 that are away from each other. The cleaning tank 1 is equipped with an elastic member adapted to the movable frame 21 and a pusher adapted to the movable frame 21. An elastic pad 32 is fixedly installed on the clamping plate 22.

[0040] The compression spring 31 is in a compressed state in the initial state. The support column 23 is in contact with the inclined surface on the push block 24. The staff places the container to be cleaned on the top of the support frame 19. When it is necessary to fix several containers, the first hydraulic telescopic rod 27 is used to drive the movable seat 25 to move upward. The movable seat 25 drives the push block 24 to move upward through the piston plate 28. The support column 23 slides on the inclined surface of the push block 24. The push block 24 can then push the support column 23, the movable frame 21, and the clamping plate 22 to slide relative to the prism 29 until the adjacent two elastic pads 32 are in contact with the container. The container is fixed relative to the clamping plate 22 and the support frame 19. Similarly, when the first hydraulic telescopic rod 27 drives the movable seat 25 to move downward, the compression spring 31 drives the movable frame 21 and the support column 23 to move horizontally in the opposite direction. The support column 23 slides reversely on the inclined surface of the push block 24, and the adjacent two elastic pads 32 are no longer in contact with the container, releasing the fixation of the container. By driving the second fixing frame 34 and the control box 2 to move vertically through the second hydraulic telescopic rod 33, the height of the second rotating shaft 7 and the cleaning roller 8 can be changed.

[0041] Example 4, on the basis of Example 1, by Figure 1 、 Figure 4 and Figure 5Given that the synchronous drive mechanism includes a third rotating shaft 35 rotatably installed in the control box 2. The top end of the first connecting shaft 12 is fixedly connected with a first bevel gear 36 located in the control box 2. A plurality of second bevel gears 37 are fixedly sleeved on the outside of the third rotating shaft 35, and the first bevel gear 36 meshes with the corresponding second bevel gear 37. A second connecting shaft 38 is rotatably connected to the control box 2. The bottom end of the second connecting shaft 38 is fixedly connected with a third bevel gear 39 located in the control box 2, and the third bevel gear 39 meshes with a corresponding second bevel gear 37. The control box 2 is equipped with a driver for driving the second connecting shaft 38 to rotate. The driver includes a fixed seat 42 arranged above the control box 2. The top end of the second connecting shaft 38 is fixedly connected with a first damping disc 40 located above the control box 2. The fixed seat 42 is fixedly installed with a servo motor 43. The output end of the servo motor 43 is fixedly connected with a second damping disc 41, and the bottom of the second damping disc 41 is in contact with the top of the first damping disc 40. At least two lead screws 44 penetrate through the fixed seat 42. The bottom end of the lead screw 44 is fixedly connected with the top of the control box 2. Two nuts 45 are sleeved on the outside of the lead screw 44, and two adjacent nuts 45 are respectively in contact with the top and bottom of the fixed seat 42;

[0042] The servo motor 43 is driven to drive the second damping disc 41 to rotate. The second damping disc 41 drives the first damping disc 40 to rotate through friction. The first damping disc 40 can drive the second connecting shaft 38 and the third bevel gear 39 to rotate. The third bevel gear 39 drives the third rotating shaft 35 to rotate through a corresponding second bevel gear 37, so that a plurality of second bevel gears 37 respectively drive the corresponding first bevel gear 36 and the first connecting shaft 12 to rotate. The staff drives the nut 45 located above the fixed seat 42 to rotate. Two adjacent nuts 45 no longer clamp the fixed seat 42. The nut 45 located above disengages from the lead screw 44, releasing the limitation on the position of the fixed seat 42. The staff drives the fixed seat 42 and the servo motor 43 to move upward, so that the fixed seat 42 disengages from the lead screw 44, and the second damping disc 41 is no longer in contact with the first damping disc 40, and the removal of the servo motor 43 can be completed.

[0043] A method for cleaning laboratory containers in this embodiment uses the laboratory container cleaning device as described above and includes the following steps:

[0044] Step 1: The staff places the container to be cleaned in the cleaning box 1, positions and fixes the container through the container positioning structure, and then the staff adds cleaning liquid into the cleaning box 1;

[0045] Step 2: According to the specifications of the container to be cleaned, the staff drives the adjustment seat 5 to rotate relative to the first rotating shaft 4, so that the distance between the axes of the second rotating shaft 7 and the first connecting shaft 12 is at a preset value, and then limits the position of the adjustment seat 5 through the locking and limiting structure, so that the adjustment seat 5 is fixed relative to the rotating seat 3;

[0046] Step 3: Drive the control box 2 to move downward through the moving member, so that the cleaning roller 8 is inserted into the corresponding container. Drive several first connecting shafts 12 to rotate synchronously through the synchronous drive mechanism. The first connecting shaft 12 drives the second rotating shaft 7 and the cleaning roller 8 to rotate synchronously through the rotating seat 3 and the adjusting seat 5, so that the cleaning roller 8 moves along the inner wall of the container.

[0047] Step 4: The meshing unit drives the first gear 6 to rotate self - sufficiently. The first gear 6 drives the second rotating shaft 7 and the cleaning roller 8 to rotate self - sufficiently through the second gear 11, changing the position where the cleaning roller 8 contacts the container, so that different positions on the cleaning roller 8 clean the inner wall of the container.

[0048] Working principle: The staff places the container to be cleaned in the cleaning box 1, positions and fixes the container through the container positioning structure. Then the staff adds cleaning liquid into the cleaning box 1. According to the specification of the container to be cleaned, the staff drives the adjusting seat 5 to rotate relative to the first rotating shaft 4. The adjusting seat 5 drives the second rotating shaft 7 and the cleaning roller 8 to move. The second gear 11 rolls on the first gear 6 so that the distance between the axes of the second rotating shaft 7 and the first connecting shaft 12 is at a preset value. Then limit the position of the adjusting seat 5 through the locking limit structure so that the adjusting seat 5 is fixed relative to the rotating seat 3. Drive the control box 2 to move downward through the moving member, so that the cleaning roller 8 is inserted into the corresponding container. Drive several first connecting shafts 12 to rotate synchronously through the synchronous drive mechanism. The first connecting shaft 12 drives the second rotating shaft 7 and the cleaning roller 8 to rotate synchronously through the rotating seat 3 and the adjusting seat 5, so that the cleaning roller 8 moves along the inner wall of the container. At the same time, the meshing unit drives the first gear 6 to rotate self - sufficiently. The first gear 6 drives the second rotating shaft 7 and the cleaning roller 8 to rotate self - sufficiently through the second gear 11, changing the position where the cleaning roller 8 contacts the container, so that different positions on the cleaning roller 8 clean the inner wall of the container, which is convenient for cleaning the inner wall of the container and ensures that the inner wall of the container can be cleaned cleanly, avoiding affecting the experimental results of the next time.

[0049] When the synchronous drive mechanism drives several first connecting shafts 12 to rotate synchronously, the first connecting shaft 12 drives the first gear 6 to roll on the toothed ring 9 through the rotating seat 3 and the first rotating shaft 4, so that the first gear 6 rotates self - sufficiently. The staff drives the first arc - shaped rack 13 and the movable column 15 to move downward, so that the first arc - shaped rack 13 is no longer meshed with the second arc - shaped rack 14. The movable column 15 drives the fixed disk 17 to move downward, and the tension spring 18 is in a stretched state. The staff drives the adjusting seat 5 to rotate relative to the first rotating shaft 4. When the adjusting seat 5 rotates to the preset position, the staff releases the first arc - shaped rack 13 and the movable column 15. The tension spring 18 drives the fixed disk 17 and the movable column 15 to move upward, so that the first arc - shaped rack 13 and the second arc - shaped rack 14 are meshed, and the adjusting seat 5 can be fixed relative to the rotating seat 3.

[0050] The compression spring 31 is initially in a compressed state, and the inclined surfaces on the support column 23 and the push block 24 are in contact. When the staff places the container to be cleaned on the top of the support frame 19 and needs to fix several containers, the first hydraulic telescopic rod 27 drives the movable seat 25 to move upward. The movable seat 25 drives the push block 24 to move upward through the piston plate 28. The support column 23 slides on the inclined surface of the push block 24, and the push block 24 can then push the support column 23, the movable frame 21, and the clamping plate 22 to slide relative to the prism 29 until the adjacent two elastic pads 32 are in contact with the container, and the container is fixed relative to the clamping plate 22 and the support frame 19. Similarly, when the first hydraulic telescopic rod 27 drives the movable seat 25 to move downward, the compression spring 31 drives the movable frame 21 and the support column 23 to move horizontally in the reverse direction. The support column 23 slides reversely on the inclined surface of the push block 24, and the adjacent two elastic pads 32 are no longer in contact with the container, releasing the fixation of the container. By driving the second fixed frame 34 and the control box 2 to move in the vertical direction through the second hydraulic telescopic rod 33, the height of the second rotating shaft 7 and the cleaning roller 8 can be changed;

[0051] The servo motor 43 drives the second damping disc 41 to rotate. The second damping disc 41 drives the first damping disc 40 to rotate through friction. The first damping disc 40 can then drive the second connecting shaft 38 and the third bevel gear 39 to rotate. The third bevel gear 39 drives the third rotating shaft 35 to rotate through a corresponding second bevel gear 37, so that several second bevel gears 37 respectively drive the corresponding first bevel gears 36 and the first connecting shafts 12 to rotate. The staff drives the nut 45 located above the fixed seat 42 to rotate, and the adjacent two nuts 45 no longer clamp the fixed seat 42. The nut 45 located above disengages from the lead screw 44, releasing the limitation of the position of the fixed seat 42. The staff drives the fixed seat 42 and the servo motor 43 to move upward so that the fixed seat 42 disengages from the lead screw 44, and the second damping disc 41 is no longer in contact with the first damping disc 40, and the removal of the servo motor 43 can be completed.
