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
