[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] like Figure 8 As shown, the feed port 201 of the ton barrel 200 is set in the middle of the top surface, and the feed port 201 is a circular structure.

[0041] like Figure 1-2 As shown, the variable diameter clamping device 2 is arranged on the outer wall of the hollow tube 1, wherein the lower ring sleeve 22 is fixed to the outer wall of the lower end of the hollow tube 1, and the upper ring sleeve 21 slides on the outer wall of the hollow tube 1 along the axial direction of the hollow tube 1. The upper end of the upper connecting rod 23 is hinged to the upper ring sleeve 21, and the lower end of the lower connecting rod 24 is hinged to the lower ring sleeve 22. The lower end of the upper connecting rod 23 and the upper end of the lower connecting rod 24 are both hinged to the clamping block 25. The upper connecting rod 23, the clamping block 25 and the lower connecting rod 24 correspond to each other one by one, and there are several upper connecting rods 23 in a circular array, several lower connecting rods 24 in a circular array, and several clamping blocks 25 in a circular array; a reset spring 27 is sleeved on the outer wall of the hollow tube 1, and the reset spring 27 is located between the upper ring sleeve 21 and the lower ring sleeve 22.

[0042] like Figure 5 As shown, the outer wall of the clamping block 25 abutting against the inner wall of the feed port 201 is in an inverted "L"-shaped structure, and a layer of rubber block 26 is provided on the outer wall of the clamping block 25. The rubber block 26 can be elastically deformed within a certain range.

[0043] like Figure 3-4 As shown, a clamping mechanism 8 is installed on the upper ring sleeve 21, and the clamping mechanism 8 includes a clamping tooth 81, a clamping strip 82 and an elastic member. The length direction of the clamping tooth 81 is consistent with the axial direction of the hollow tube 1, and the clamping strip 82 is slidably connected to the upper ring sleeve 21.

[0044] like Figure 1 As shown, water-blocking cloths 28 are provided on the lower connecting rods 24 of the annular arrays and the clamping blocks 25 of the annular arrays to form an umbrella-like structure.

[0045] like Figure 1 and 6 As shown, a power device 4 is provided under the hollow tube 1, and the power device 4 includes a shell 41, a slider 42, a first rotating device 43 and a second rotating device 44. The shell 41 is installed at the output end of the second rotating device 44, and a slide groove 411 is provided on the shell 41. The slider 42 slides in an arc shape on the slide groove 411. The first rotating device 43 is installed inside the shell 41 to drive the slider 42 to rotate; the rotation axes of the first rotating device 43 and the second rotating device 44 are perpendicular to each other; the nozzle 5, the camera 6 and the infrared emitter 7 are installed on the outer wall of the slider 42.

[0046] like Figure 6 As shown, although there is a certain blind spot when the slider 42 rotates toward the second power device 44, this blind spot is just aligned with the feed port 201, so that when the first rotating device 43 and the second rotating device 44 cooperate to drive the slider 42 to rotate, the nozzle 5 on the slider 42 can be aligned with any position on the inner wall of the ton barrel 200 except the feed port 201.

[0047] like Figure 1 As shown, the high-pressure water flow ejected by the nozzle 5 has a fan-shaped structure.

[0048] like Figure 7 As shown, a folding cover 3 is connected between the lower end of the hollow tube 1 and the lower edge of the second power device 44, and the upper part of the second power device 44 is adapted to the opening of the lower end of the hollow tube 1; a sliding sleeve 9 is slidably connected to the upper part of the outer wall of the hollow tube 1, and another set of clamping mechanisms 8 is installed on the sliding sleeve 9; four groups of evenly distributed traction ropes 10 are connected between the sliding sleeve 9 and the second power device 44, and a limiting guide sleeve 101 is provided on the inner wall of the hollow tube 1 and the inner wall of the folding cover 3, and the traction rope 10 passes through the limiting guide sleeve 101.

[0049] Working principle:

[0050] Place the clamping blocks 25 in the annular array into the feed port 201, manually push the upper ring 21 toward the lower ring 22, and compress the return spring to generate a reverse elastic force. During this process, the clamping blocks 25 in the annular array are pushed outward by the upper connecting rod 23 and the lower connecting rod 24, so that the rubber blocks 26 on the outer walls of the clamping blocks 25 in the annular array are tightly abutted against the inner wall of the feed port 201.

[0051] like Figure 4As shown, the arrow indicates the direction in which the upper ring sleeve 21 approaches the lower ring sleeve 22. During this process, the left end of the clamping strip 82 can unidirectionally cross the latching tooth 81. The elastic force of the elastic member pushes the left end of the clamping strip 82 to engage with the latching tooth 81. When the left end of the clamping strip 82 is engaged with the latching tooth 81, the left end of the clamping strip 82 cannot reversely cross the latching tooth 81; thereby preventing the upper ring sleeve 21 from moving away from the lower ring sleeve 22, thereby achieving the multiple annular array of clamping blocks 25 being fitted and fixed to the inner wall of the feed port 201, thereby securing the hollow tube 1 relative to the ton barrel 200. At this time, the unfolded water retaining cloth 28 relatively closes the feed port 201.

[0052] The clamping strip 82 is manually dragged away from the clamping teeth 81 and the elastic member is compressed to generate a reverse elastic force. At this time, the upper ring sleeve 21 can be moved up and down arbitrarily to move closer to or away from the lower ring sleeve 22.

[0053] like Figure 5 As shown, the vertical end of the clamping block 25 is in contact with the inner wall of the feed port 201, the horizontal end of the clamping block 25 is located above the vertical end of the clamping block 25, and the horizontal end of the clamping block 25 is located above the top wall of the feed port 201, thereby preventing the entire equipment from falling into the ton barrel 200 when the clamping force is insufficient.

[0054] First, the sliding sleeve 9 slides down relative to the hollow tube 1, and the second rotating device 44 is driven by the traction rope 10 to approach the lower end of the hollow tube 1, so that the upper part of the second rotating device 44 is inserted into the lower end opening of the hollow tube 1. Then, the clamping mechanism 8 fixes the corresponding sliding sleeve 9 to the outer wall of the hollow tube 1; at this time, the second rotating device 44 is fixed relative to the hollow tube 1;

[0055] Then, the first rotating device 43 and the second rotating device 44 are controlled by an external controller to cooperate with each other to drive the slider 42 to rotate according to the set program, so that the nozzle 5 on the slider 42 performs all-round high-pressure water spraying on the inner wall of the ton barrel 200 according to the set trajectory to achieve water washing.

[0056] During the water washing process, the water-blocking cloth 28 closes the feed port 201 to prevent water from splashing out of the feed port 201 , and the water in the ton barrel 200 is discharged from the discharge port at the bottom of the side wall.

[0057] The camera 6 of the visual recognition system is installed on the slider 42. The camera 6 and the infrared emitter 7 move synchronously with the nozzle 5. Under normal circumstances, the infrared generator 7 does not work. The camera 6 transmits the image information of the inner wall of the ton barrel 200 before and after cleaning to the controller of the visual recognition system. The controller compares the image information of the inner wall of the ton barrel 200 before and after cleaning, and determines the cleaning effect of this area based on the comparison structure.

[0058] Furthermore, the controller of the visual recognition system also pre-stores image information of the ton barrel 200 when it is clean. The image information after cleaning is compared with the pre-stored image information (equivalent to the image information of the inner wall of the ton barrel 200 before cleaning), and the cleaning effect of this area is judged based on the comparison structure.

[0059] If the visual recognition system determines that an area is not cleaned properly, the controller records the position information of the first rotating device 43 and the second rotating device 44 in this area; after cleaning is completed, the first rotating device 43 and the second rotating device 44 drive the slider 42 to rotate and align with the recorded uncleaned area according to the position information recorded by the controller. At the same time, the infrared emitter 7 emits infrared visible light to point to the uncleaned area. Since the ton barrel 200 is blow-molded with high molecular weight and high density polyethylene and has a certain light transmittance, the staff can observe the area irradiated by the infrared and visible light from the outside, so as to know which areas are not cleaned properly.

[0060] Staff can use a marking pen to mark the location where the infrared and visible light is irradiated.

[0061] Afterwards, the clamping mechanism 8 on the sliding sleeve 9 is released, and the sliding sleeve 9 moves up to the upper limit position relative to the hollow tube 1. At this time, the second rotating device 44 can be away from the lower end of the hollow tube 1. At this time, the slider 42 can move freely relative to the hollow tube 1; after that, the staff passes one hand through the hollow tube 1 and holds the upper end of the second rotating device 44, and the folding cover 3 can be extended and rotated arbitrarily. Since the traction rope 10 can be deformed arbitrarily, the staff can drive the nozzle 5 on the slider 42 to move and rotate arbitrarily in the ton barrel 200, and can adjust the distance between the nozzle 5 and the unclean area at will, and can control the nozzle 5 to spray the unclean area at multiple angles; thereby realizing manual flushing of the unclean area; during the flushing process, real-time shooting can be carried out through the camera 6, and the staff can observe the cleaning situation through the external display screen.

[0062] In addition, some areas of the inner wall of the ton barrel 200 are not flat, and the in-situ universal rotation of the nozzle 5 may not have a very good cleaning effect.

[0063] Example 2: Improved on the basis of Example 1:

[0064] Because there may be multiple areas where the 200 ton barrel is not cleaned properly; Figure 6 、 8As shown in Figure 9, the housing 41 has a built-in first magnetic member 45, the positioning member 300 has a built-in second magnetic member 301, and the positioning member 300 is provided with an adhesive member (such as tape). When the infrared emitter 7 emits infrared visible light, the positioning member 300 is temporarily fixed to the infrared visible light irradiation position of the outer wall of the ton barrel 200 through the adhesive member; thus, when the staff holds the second rotating device 44 and drives the nozzle 5 to approach the unclean area, since the unclean area cannot be directly observed by the naked eye, at this time, the magnetic attraction between the first magnetic member 45 and the second magnetic member 301 is conducive to rapid positioning and speeds up work efficiency.

[0065] Example 3: Improved on the basis of Example 2:

[0066] like Figure 9 As shown, the solid glue 303 is arranged in the glue cylinder 302, and the glue cylinder 302 is threadedly connected to the middle part of the positioning member 300. The second magnetic member 301 is annular and relatively surrounds the outside of the solid glue 303; by rotating the glue cylinder 302 relative to the positioning member 300, the thickness of one end of the solid glue 303 exposed to the outside can be adjusted. If the solid glue 303 is exposed to the outside for too long, it will not only be easily wasted, but also easily broken.

[0067] The motor in the first rotating device 43 and the second rotating device 44 both adopt micro servo / stepper motors, whose wires are connected to the outside through the inner cavity of the hollow tube 1; a fill light can also be installed on the slider 42; the nozzle 5 is connected to the rotating water joint through a first hose, and the rotating water joint is connected to the external water source through a second hose.
