Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
A pipeline cleaning method is characterized in that a cleaning device with a nozzle is used for walking in a pipeline, the nozzle is connected with a hollow shaft with a cleaning medium conveying function, and the nozzle rotates around the axis of the hollow shaft to spray the cleaning medium on the circumferential inner wall of the pipeline.
The cleaning device can walk in the pipeline, namely the cleaning device at least comprises a driving structure for driving the cleaning device to move and an electricity storage structure for supplying electricity to the driving structure, and the driving structure can also be connected with an external power supply through an external wire. The nozzle is mounted on the frame by a hollow shaft mounted in the frame of the cleaning device and allows the nozzle to rotate synchronously around the axis of the hollow shaft during the movement of the cleaning device, so that the rotating nozzle sprays the cleaning medium on the axial inner wall of the pipeline to be cleaned, namely the pipeline is cleaned. Meanwhile, because the hollow shaft is used as a rotating fulcrum of the nozzle and a conveying structure of the cleaning medium in the embodiment, compared with the patent (Chinese patent CN 109365440A) previously applied by the applicant, the hollow shaft cleaning device has smaller volume and lower weight, and can be suitable for the requirement of cleaning a pipeline with smaller pipe diameter. In this embodiment, the nozzle may be rotated by the hollow shaft or an additional driving structure, and the structure for mediating the rotation may be various, such as a gear transmission, a belt transmission, a connecting rod transmission, or the like.
Referring to fig. 1, the cleaning apparatus has a first driving mechanism 8 and a hollow shaft 5 mounted on a frame 1; and a nozzle 2 and a second drive structure 3; the first driving structure 8 is used for driving the rack 1 to walk in a pipeline; one end of the hollow shaft 5 is connected with the nozzle 2, and the other end of the hollow shaft is connected with a cleaning medium storage structure 16 through a pipeline 15; the second drive mechanism 3 is used to drive the nozzle 2 to rotate about the axis of the hollow shaft 5.
The first driving structure 8 is mounted on the frame 1, and is used for driving the frame 1 to communicate with the nozzle 2 and the like to walk in the pipeline. The hollow shaft 5 extends through the frame 1 so that when one end (head) thereof is used to connect the nozzle 2, the other end (tail) thereof is connected to the cleaning medium storage structure 16 via the pipe 15, thereby avoiding interference with the movement of the cleaning device while the pipe 15 increases the overall radial dimension of the cleaning device. The nozzle 2 is mounted at the head of the hollow shaft 5, and the 360-degree rotation of the nozzle 2 around the axis of the hollow shaft 5 is realized by the second driving structure 3, so that the nozzle 2 can spray cleaning media on the circumferential inner wall of the pipeline without dead angles. It will therefore be understood that in this embodiment the nozzle 2 is either a unitary structure with its water outlet bent away from the axis of the hollow shaft 5 or a split joint of a combination of straight and curved tubes.
In a preferred embodiment, the nozzle 2 is mounted on the hollow shaft 5 by means of a rotary joint 10. At this time, due to the structural characteristics of the rotary joint 10, that is, the front end and the rear end of the rotary joint 10 can rotate with each other without mutual influence, the nozzle 2 is mounted at the front end of the rotary joint 10, and one end of the hollow shaft 5 is mounted at the rear end of the rotary joint 10, so that the influence of the rotation of the nozzle 2 and the hollow shaft 5 with each other can be effectively avoided, that is, the second driving mechanism 3 drives the nozzle 2 to rotate alone in this embodiment. In an alternative embodiment, the second drive 3 is in driving connection with the nozzle 2 via a first gear train 4.
In one embodiment, the frame 1 has a support structure mounted thereon for holding the cleaning device coaxial with the pipe.
The supporting structure comprises at least two opposite supports 7 which are hinged to the rack 1, the first driving structure 8 is mounted on the supports 7, a driving wheel 9 is arranged at one end, far away from the rack 1, of each support 7, and the first driving structure 8 is electrically connected with the driving wheel 9. One end of the bracket 7 is hinged on the frame 1, the other end of the bracket is provided with a driving wheel 9, and the rotation of the driving wheel 9 is realized through the first driving structure 8, namely, in the embodiment, at least two brackets 7 are unfolded through the bracket 7 and the driving wheels 9 abut against the inner wall of the pipeline, so that the cleaning device is driven to move back and forth while being coaxial with the pipeline. The number of the supports 7 is optional, generally, the more the supports 7 are arranged, the higher the stability of the cleaning device in the advancing process, but the overall weight of the cleaning device is too large, so that the difficulty of the cleaning device in walking on a vertical pipeline is improved, and therefore, the number of the supports 7 is preferably six. Six supports 7 are uniformly distributed in the axial direction of the rack 1 at equal intervals, and the inclination angles of the adjacent supports 7 are opposite, namely, the driving wheel 9 on one support 7 is arranged towards the tail of the hollow shaft 5, and the driving wheel 9 on the adjacent support 7 is arranged towards the head of the hollow shaft 5, namely, the adjacent supports 7 are arranged in a staggered manner. At the same time, the axis of the hollow shaft 5 lies on or intersects the plane of the plane swept by the axis of the stent 7 during the expansion or contraction of the stent 7.
In one embodiment, the cleaning device further comprises a third driving structure 13, a nut 11, a reducing assembly 6 and a support arm 12; the third driving structure 13 is used for driving the hollow shaft 5 to rotate along the axis thereof; the nut 11 and the reducing assembly 6 are both arranged on the hollow shaft 5 and are in threaded connection with the hollow shaft 5; one end of the support arm 12 is hinged on the reducing component 6, and the other end is hinged on the support 7. Wherein the third driving structure 13 drives the hollow shaft 5 through the second gear set 14 to drive the hollow shaft 5 to rotate along the circumference/around the axis thereof. In this embodiment, the hollow shaft 5 is similar to a lead screw, and is provided with a variable diameter assembly 6 and a nut 11 which are connected with the lead screw through threads, wherein one end of an arm 12 is hinged on the variable diameter assembly 6, and the other end of the arm 12 is hinged on the bracket 7, so that when the third driving structure 13 drives the hollow shaft 5 to rotate, the variable diameter assembly 6 and the nut 11 can freely slide on the hollow shaft 5, and therefore, the bracket 7 can be expanded or contracted through the arm 12, namely, the radial dimension of the cleaning device can be adjusted, and therefore, the requirements of pipelines with different pipe diameters can be met. In an alternative embodiment, the third driving structure 13 is a variable diameter motor.
In one embodiment, the arm 12 is a telescopic rod, the arm 12 includes an inner tube and an outer tube, the inner tube and the outer tube are both provided with a convex edge 121 extending along a radial direction thereof, and a spring 122 is disposed between the two convex edges 121, that is, the spring 122 is used to buffer the arm 12 during the extension and retraction process.
Referring to fig. 2 and 3, in an alternative embodiment, a tee structure 17 is further disposed at an end of the bracket 7 away from the rack 1, and the tee structure 17 includes a fixing plate 171, a rotating shaft 173, a roller 172 and a belt 174. Wherein the fixing plate 171 is fixed on the bracket 7, the rollers 172 are arranged in at least three numbers and are mounted on the fixing plate 171, the three numbers are distributed in a substantially triangular shape, one of the rollers 172 is connected with the rotating shaft 173, and the belt 174 is bridged on the three rollers 172 and is tensioned by the three rollers 172. The fixing plate 171 is inclined toward the axis of the hollow shaft 5, that is, when the driving wheel 9 falls into the tee pipe due to gravity, the belt 174 is preferentially contacted with the wall of the tee pipe, so that the driving wheel 9 is prevented from falling into the tee pipe further, and the belt 174 is rotated to take the tee pipe out of the driving wheel 9. The rotation of the belt 174 is achieved by the overall displacement of the cleaning device caused by the rotation of the other driving wheel 9, i.e. in this embodiment the three-way structure 17 allows the cleaning device to continue to advance safely in a pipe with a three-way pipe.
