[0026] See also Figures 1 to 7A drum inner wall cleaning device includes a spray assembly 20, a bracket 10 and a telescopic rod 30. A roller 11 is provided at the bottom of the bracket 10, and a support 40 is provided on the bracket 10. One end of the telescopic rod 30 is connected to the support 40, and the other end is located outside the drum 70; the spray assembly 20 includes a connector 21 and a spray head 22. A mounting plate 41 is provided on the front side of the support 40, and the mounting plate 41 is hingedly connected to the support 40. The connector 21 is fixedly provided on the mounting plate 41. A plurality of spray heads 22 are evenly spaced around the connector 21 in the circumferential direction. The connector 21 is connected to a water source. A cylinder 50 is provided at the bottom of the support 40, and the telescopic end of the cylinder 50 is connected to the mounting plate 41. The staff can adjust the length of the telescopic rod 30 according to the depth of the drum 70, and drive the telescopic rod 30 to move by holding the other end of the telescopic rod 30, driving the bracket 10 and the spray assembly 20 thereon to move on the drum 70 to clean the inner wall of the drum 70; the cylinder 50 is used to control the swing of the spray assembly 20 to change the spraying direction of the spray head 22 and clean the dead corners inside the drum 70.

[0027] See also Figure 1 、 Figure 2 and Figure 6 Considering the curved inner wall of the drum 70, the outer contour of the bracket 10 is an isosceles triangle to ensure stable movement on the inner wall of the drum 70. Two rollers 11 are disposed on either side of the bottom of the bracket 10. The bracket 10 contacts the inner wall of the drum 70 via the two rollers 11, thereby improving the stability of the bracket 10's movement. Specifically, the bracket 10 includes two metal rods arranged at an angle relative to each other, with the two rollers 11 respectively disposed at the bottom of the two metal rods. The two metal rods are connected at the middle by a horizontal connecting rod 12 to enhance the structural strength of the bracket 10.

[0028] Support 40 is mounted on top of bracket 10, with the bottom of support 40 connected to the tops of two metal rods. The side of support 40 facing the direction of movement of bracket 10 is defined as the front side. Mounting plate 41 is mounted on the front side of support 40, with side panels flanking mounting plate 41. These side panels are hingedly connected to the left and right sides of support 40. Cylinder 50 is mounted on the bottom of support 40, with its extension and retraction direction facing the front side. The retracting end of cylinder 50 is hingedly connected to mounting plate 41. When cylinder 50 extends, it pushes mounting plate 41 to rotate around support 40, thereby causing spray assembly 20 on mounting plate 41 to swing, changing the spraying direction of spray assembly 20.

[0029] The shower assembly 20 includes a connector 21 and several shower heads 22. The shower heads 22 are common high-pressure shower heads, and the connector 21 is a multi-way water pipe connector. Specifically, the connector 21 has a regular hexagonal cross-section, with mounting holes for the shower heads 22 defined on each of its six circumferential surfaces. The shower heads 22 are connected to the mounting holes via quick-connect connectors. A through hole for connecting to a water pipe is provided on one end face of the connector 21, communicating with the mounting hole. The connector 21 is connected to a water source via a water pipe (not shown).

[0030] Support 40 is provided with a channel to avoid water pipes and facilitate their layout. Sprinkler head 22 is fixed to mounting plate 41 via connector 21. A water pipe is installed within the channel, connecting connector 21 with a water source. In this embodiment, support 40 is a U-shaped plate with its bottom fixedly connected to bracket 10. The water pipe passes through the center of support 40 to connect connector 21 with an external water source.

[0031] Preferably, the height of the bracket 10 should be such that when the bracket 10 is clamped inside the drum 70, the center of the connecting member 21 is located on the central axis of the drum 70, so that the distance between any spray head 22 on the connecting member 21 and the inner wall of the drum 70 is equal. When the bracket 10 moves, the spray assembly 20 moves along the central axis of the drum 70, and the impact force of any spray head 22 on the inner wall of the drum 70 is the same, and the cleaning effect is consistent.

[0032] The support 40 is provided with a vertical plate 42, and the telescopic rod 30 is connected to the support 40 through the vertical plate 42, thereby driving the movement of the bracket 10. Specifically, the vertical plate 42 is vertically fixed to the top of the support 40. The upper end of the vertical plate 42 is provided with a connecting hole 421. The end of the telescopic rod 30 is provided with a threaded hole. The end of the telescopic rod 30 is inserted into the connecting hole 421. The end of the telescopic rod 30 is provided with a bolt 31. The bolt 31 is threadedly connected to the end of the telescopic rod 30 through the connecting hole 421 on the vertical plate 42, thereby fixing the telescopic rod 30 to the vertical plate 42. The staff can move the telescopic rod 30 to drive the movement of the bracket 10.

[0033] In this embodiment, the telescopic rod 30 is a snap-on telescopic rod 30, the end of which is connected to the vertical plate 42, making it easy for the operator to connect. The method of moving the bracket 10 using the telescopic rod 30 is as follows: first, the end of the telescopic rod 30 is connected to the vertical plate 42, the bracket 10 is located inside the drum 70, and the operator is located outside the drum 70 and holds the other end of the telescopic rod 30. By moving the telescopic rod 30 into the drum 70, the bracket 10 moves inside the drum 70, and the spray assembly 20 cleans the inner wall of the drum 70. As the telescopic rod 30 gradually moves deeper into the drum 70, the operator adjusts the length of the telescopic rod 30 accordingly so that the bracket 10 spray assembly 20 can move into the drum 70 for cleaning.

[0034] Furthermore, a support plate 13 is tilted between the telescopic rod 30 and the bracket 10. Specifically, a fixing member 32 is sleeved onto the telescopic rod 30, located near the end of the telescopic rod 30. The support plate 13 is a triangular plate, with its top corner hingedly connected to the bottom of the fixing member 32, and its bottom corner detachably connected to the connecting rod 12 in the middle of the bracket 10 via screws. When the ends of the support plate 13 are respectively connected to the fixing member 32 and the bracket 10, the support plate 13 is in an inclined position, forming a triangular structure between the support plate 13, the bracket 10, and the telescopic rod 30. This improves the connection strength between the telescopic rod 30 and the bracket 10, ensuring that the connection between the telescopic rod 30 and the bracket 10 remains stable when the operator pushes the bracket 10 to move, and the bracket 10 moves stably along the inner wall of the roller 70 under the action of the telescopic rod 30.

[0035] When not in use, the bottom corner end of the support plate 13 is disassembled from the connecting rod 12 in the middle of the bracket 10, and the support plate 13 is rotated to make it close to the telescopic rod 30; the top of the bracket 10 and the bottom of the support 40 are loosened, and the bracket 10 is rotated to make it close to the telescopic rod 30 to complete the folding for easy storage. Figure 3 shown.

[0036] See also Figure 4 and Figure 5 , further comprising a mobile trolley 60, on which is provided a storage box 61 for storing the folded cleaning device. Furthermore, the mobile trolley 60 is provided with a stand 62, on which is provided an M-shaped support platform 63 for auxiliary support of the telescopic rod 30; specifically, when the telescopic rod 30 is moved to drive the spray assembly 20 to clean in the drum 70, the end of the telescopic rod 30 can be mounted on the support platform 63 to assist the staff in supporting the telescopic rod 30, such as Figure 7 A pneumatic control valve 64 is also provided on the stand 62. The air cylinder 50 is connected to the pneumatic control valve 64 via an air pipe (not shown). A worker can manually operate the pneumatic control valve 64 to change the air supply state, extending or retracting the air cylinder 50, thereby driving the spray assembly 20 to swing up and down, changing the spray direction of the spray head 22 and cleaning the blind spots on the inner wall of the drum 70.

[0037] Furthermore, a fixing belt for fixing the rod is provided on the stand 62. After the telescopic rod 30 and the stand 62 are disassembled, the folded bracket 10 is stored in the storage box 61, and the folded telescopic rod 30 is fixed to the stand 62 by the fixing belt. When the cleaning device is not in use, it is disassembled, folded and stored, and the stored cleaning device is transferred using the mobile trolley 60. Figure 4 shown.

[0038] In this embodiment, a water tank is further provided on the mobile vehicle 60 , and the water tank is connected to the spray assembly 20 through a water pipe, serving as a water source for cleaning the spray assembly 20 .
