Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.As long as in addition, technical characteristic involved in each embodiment of invention described below Not forming conflict each other can be mutually combined.
As shown in Figure 1, high-pressure water jet circulator, spray boom and the nozzle for producing water jet are installed inside cleaning disk, High pressure water enters cleaning disk intracavitary by the entrance of circulator 16 and decontaminates, and caused waste water passes through under the action of vacuum negative pressure Processing is recycled by vacuum water out adapter 17;At the same time, the true of cleaning disk inner cavity can be changed by adjusting breather valve 18 Reciprocal of duty cycle, ensures the recycling of waste water.
Obstacle detouring sleeve 5 is connected with high molecular polythene friction pad 14 through soft rubber 13, and soft rubber one end is by anchor ear 11 with getting over Barrier sleeve 5 is fixed, and the other end is fixed by bolt 12 and high molecular polythene friction pad 14.Cricoid high molecular polythene friction pad 14 sufficiently thin make it have certain flexibility.
Obstacle detouring performance analysis is carried out with reference to Fig. 2, cleaning disk advances runs into barrier forward, such as weld seam or small scale Bump.Due to the form that upsweeps at 14 edge of high molecular polythene friction pad, its edge can smooth climbing barrier.Due to The characteristic of soft rubber 13, the upward movement of 14 outer rim of high molecular polythene friction pad will not cause the upward of obstacle detouring sleeve 5 at once Movement.As barrier continues to move to intracavitary, obstacle detouring sleeve lower wing plate is connect be subject to 14 inner edge of high molecular polythene friction pad Touch and be gradually lifted up, make to compress with the spring mechanism that is connected of cleaning disk, so that obstacle detouring sleeve 5 is close to barrier Part be substantially higher than barrier.At the same time, 14 outer rim of high molecular polythene friction pad can under gravity gradually with Working face is bonded again, and then ensure that the scope of effective vacuum inside obstacle detouring Cleaning Process disk.In barrier with being somebody's turn to do During organizational separation, before obstacle detouring sleeve 5 can return to obstacle-produced turbulence under the collective effect of spring mechanism and self gravitation State, process just with into fashionable opposite.
