Taking a general view of the paper, major innovative ideas and returns are as follows: The main innovative ideas are as follows: 1. The paper put forward the new idea that combine water-saving drilling with rotary percussion drilling creatively according to the present situation of water resource lack seriously and the background of implementation of state geological survey strategy. 2. The working principle of new designed system of water-saving hydraulic percussion device completely different from traditional hydraulic percussion device, the system can carry out rotary percussion drilling on the condition that no surface water be consumed, and achieve the purposes that saving surface water, cutting cost and improving drilling efficiency. 3. The design conception of steel ball percussion device is very novel, the percussion device is durable, with a simple structure, at the same time drilling efficiency would be improved highly and drilling cost would be reduced greatly when drill with the steel ball percussion device.

综观全文，论文的主要创新点及研究成果如下：主要创新点： 1、结合我国许多地区水资源严重短缺的现状以及国家实施地质大调查战略的背景，创造性地提出了&节水钻探&和&回转冲击钻进&结合起来的新思维； 2、设计出的节水型液动冲击器系统，其工作原理跳出了传统液动冲击器要消耗大量地表水的原理模式，在基本不消耗地表水的情况下便能实现回转冲击钻进，达到节约地表水、降低成本、提高钻探效率的目的； 3、设计的球体冲击器构思新颖，克服了同类产品冲击功传递效率低的弊端、且结构简单、经久耐用，可大幅度提高钻探效率、降低钻探成本。
