DETAILED DESCRIPTION

[0029] The technical scheme of the utility model will be described in further detail below through specific embodiments.

[0030] As Figures 1-7 shown, the cylinder cleaning device of the utility model comprises first pipe shaft 10 and second pipe shaft 20, first pipe shaft 10 is communicated with second pipe shaft 20, nozzle 30 is arranged on second pipe shaft 20, nozzle 30 is communicated with second pipe shaft 20, first pipe shaft 10 provides high-pressure water source or compressed air for second pipe shaft 20, and second pipe shaft 20 provides high-pressure water source or compressed air for nozzle 30.

[0031] As Figure 1 , Figure 2 shown, first pipe shaft 10 rotates around its own axis, and second pipe shaft 20 rotates with first pipe shaft 10; in this way, nozzle 30 also rotates with first pipe shaft 10, and nozzle 30 can rotate 360 degrees around the axis of first pipe shaft 10.

[0032] As Figure 1 , Figure 2 shown, second pipe shaft 20 also rotates around its own axis; in this way, nozzle 30 also rotates with second pipe shaft 20, and nozzle 30 can rotate 360 degrees around the axis of second pipe shaft 20.

[0033] The orientation direction of the nozzle 30 coincides with the radial direction of the second pipe shaft 20. According to the orientation of the nozzle 30, a theoretical cleaning plane is formed when the jet path of the nozzle 30 rotates 360 degrees around the axis of the second pipe shaft 20. Moreover, the first pipe shaft 10 and the second pipe shaft 20 are perpendicular to each other, so the cleaning plane is parallel to the axis of the first pipe shaft 10. When the nozzle 30 rotates around the axis of the first pipe shaft 10, the cleaning plane rotates around the axis of the first pipe shaft 10. Thus, based on the rotation of the first pipe shaft 10 and the second pipe shaft 20, when the nozzle 30 of the cylinder cleaning device penetrates into the cylinder structure along the axial direction of the cylinder, if the nozzle 30 has sufficient jet strength, the nozzle 30 can theoretically clean the side wall of the entire area and the end face of most of the area in the cylinder, having a wide cleaning range.

[0034] As shown in Figure 1 , Figure 2 , as a preferred embodiment, the nozzle 30 is provided as a single nozzle. In other embodiments, the nozzle 30 can also be provided as multiple nozzles. The number of nozzles 30 can be set according to the required pressure of the nozzle 30 and the pressure provided by the pipe, so that the pipe can provide a high-pressure water source or compressed air to the nozzle 30, and the nozzle 30 can still reach the required output pressure after the pipe provides the high-pressure water source or compressed air to the nozzle 30, to ensure good cleaning effect and a longer cleaning range.

[0035] As shown in Figure 2 , a bend pipe 21 and a second rotary joint 22 are provided between the first pipe shaft 10 and the second pipe shaft 20. The bend pipe 21 is connected to the first pipe shaft 10, and the bend pipe 21 is connected to the second pipe shaft 20 through the second rotary joint 22. As a preferred embodiment, the bend pipe 21 can be provided integrally with the first pipe shaft 10, i.e., one end of the first pipe shaft 10 is provided as the bend pipe 21. In other embodiments, the bend pipe 21 can be provided separately from the first pipe shaft 10, and the two are fixedly connected. The second rotary joint 22 includes a fixed end and a rotating end. The bend pipe 21 is connected to the fixed end, and the second pipe shaft 20 is connected to the rotating end. The second rotary joint 22 ensures the passage while allowing the second pipe shaft 20 to rotate around its own axis relative to the first pipe shaft 10.

[0036] The position of the cleaning plane (formed by the 360-degree rotation of the nozzle 30 around the axis of the second pipe shaft 20) can be adjusted by the elbow 21 and the second rotary joint 22. As preferred, the orientation direction of the nozzle 30 intersects or coincides with the extension direction of the axis of the first pipe shaft 10, that is, the plane formed by the rotation route of the jetting direction of the nozzle 30 (i.e. the cleaning plane) coincides with the axis of the first pipe shaft 10, that is, the cleaning plane coincides with the axis of the first pipe shaft 10. In this way, the barrel cleaning device has a wider cleaning range, and the overall structure is more stable when the first pipe shaft 10 and the second pipe shaft 20 rotate, and has good dynamic balance.

[0037] As shown in Figures 1-6 , the first pipe shaft 10 is provided with a second motor 23, and the second motor 23 is connected with a motor fixing block 27 fixedly clamped on the first pipe shaft 10. The second pipe shaft 20 is provided with a turbine 26, and the second motor 23 drives the second pipe shaft 20 through a transmission shaft 24, a worm 25 and the turbine 26 to rotate around its own axis. The two ends of the worm 25 are provided with bearing members which can be arranged on the nozzle housing 40 described below. In this way, when the first pipe shaft 10 rotates around its own axis, the second motor 23, the transmission shaft 24, the worm 25, the turbine 26, the motor fixing block 27 and the second pipe shaft 20 will also rotate as a whole, and at the same time the second pipe shaft 20 can also rotate around its own axis. When there is a coaxial alignment problem between the transmission shaft 24 and the worm 25, a transmission shaft universal joint 28 can be arranged between the transmission shaft 24 and the worm 25 to smoothly transmit power.

[0038] As shown in Figure 2 , Figure 7 , the barrel cleaning device further comprises a nozzle housing 40 (part of the nozzle housing 40 not shown in Figure 2 is represented by a dashed line), which is fixedly connected with the first pipe shaft 10 and rotates with the first pipe shaft 10, and rotates around the axis of the first pipe shaft 10. The second pipe shaft 20 is rotatably arranged on the nozzle housing 40. The nozzle housing 40 is provided with a slot 41, the second pipe shaft 20 is vertically arranged in the slot 41, and the nozzle 30 is arranged in the slot 41, and the slot 41 is parallel to the axis of the first pipe shaft 10. In this way, the cleaning plane (formed by the 360-degree rotation of the nozzle 30 around the axis of the second pipe shaft 20) coincides with the slot 41, and the nozzle 30 sprays outward from the slot 41 to complete the cleaning.

[0039] If the bottom surface of the one-groove 41 is set as a plane, the cleaning plane is blocked by the bottom surface of the one-groove 41, and the effective range of the nozzle 30 is greater than 180 degrees. According to the position of the nozzle 30 in the cylinder, theoretically, the nozzle 30 can clean the entire area of the side wall in the cylinder. In order to ensure that the nozzle 30 can clean the entire area of the side wall and most of the area of the end surface of the cylinder, the bottom surface of the one-groove 41 is provided with an outwardly open inclined groove 42, which is symmetrically arranged on both sides of the second pipeline rotating shaft 20. The inclined groove 42 is used to increase the effective cleaning angle of the nozzle 30 when rotating, reduce the blockage of the bottom surface of the one-groove 41 to the cleaning plane, and make the effective range of the nozzle 30 much greater than 180 degrees (such as about 270 degrees as shown in Figure 5 The bottom surface of the one-groove 41 can reduce the blockage of the cleaning plane, and when the nozzle 30 penetrates into the cylinder, it can clean the entire area of the side wall and most of the area of the end surface in the cylinder, so that the cleaning plane of the nozzle 30 can act on more areas in the cylinder.

[0040] Based on the above, the nozzle head shell 40 can protect the nozzle 30 from damage, and at the same time will not excessively block the cleaning range of the nozzle 30; the elbow 21 and the second rotating joint 22 are protected by the nozzle head shell 40, preventing the second rotating joint 22 from being contaminated and causing jamming; the nozzle head shell 40 separates the nozzle 30 and the related driving components (part of the transmission shaft 24, the worm 25, the turbine 26, the transmission shaft universal joint 28, etc.) of the second pipeline rotating shaft 20, preventing the driving components of the second pipeline rotating shaft 20 from being contaminated and causing jamming.

[0041] Based on the above, when the elbow 21 is inside the nozzle head shell 40, it can be bent at the inclined groove 42 to connect the second rotating joint 22, and the second rotating joint 22 is located on one side of the one-groove 41, while the driving components of the second pipeline rotating shaft 20 can be arranged on the other side of the one-groove 41 inside the nozzle head shell 40; at this time, one end of the second pipeline rotating shaft 20 at the end of the one-groove 41 is connected to the second rotating joint 22, and the other end is provided with the turbine 26 and connected to the worm 25.

[0042] Based on the above, the nozzle head shell 40 is in the shape of a cylinder, and the end of the nozzle head shell 40 is in the shape of a dome, which is conducive to the rotation and penetration of the nozzle head shell 40 into the cylinder.

[0043] Based on the above, when the second motor 23 is working, the second pipeline rotating shaft 20 can be driven to rotate in one direction all the time, or the second pipeline rotating shaft 20 can be driven to periodically change the rotating direction to avoid the bottom surface of the linear slot 41, so as to form the swing of the nozzle 30; for example, in combination with the above, when the cleaning range of the nozzle 30 is 270 degrees due to the setting of the inclined groove 42, the swing angle of the nozzle 30 is 270 degrees, and when the orientation of the nozzle 30 is parallel to the inclined groove 42, the rotating direction of the second pipeline rotating shaft 20 is changed, and the swing is repeated in this way.

[0045] Based on the above, the rotational connection between the first pipeline rotating shaft 10 and the base 50 is realized through a first rotary joint 12 and a supporting bearing 14. As shown in Figure 3 , the first rotary joint 12 comprises a rotating end and a fixed end, the first pipeline rotating shaft 10 is connected with the rotating end of the first rotary joint 12, and the base 50 is connected with the fixed end of the first rotary joint 12; the fixed end of the first rotary joint 12 is further connected with a pipeline for providing a high-pressure water source or compressed air, and the first rotary joint 12 is connected with the first pipeline rotating shaft 10 in communication for providing the first pipeline rotating shaft 10 with the high-pressure water source or the compressed air.
