The Tunnel Boring Machine, which “moves forward in the dark”, is eager to have a pair of “eyes” to explore the tunnel ahead, so as to quickly judge the “unpredictability” ahead, and break the rock for tunneling steadily and safely! Such an important “eye” comes from Jinan, China.
This advanced 3D seismic detection device and method for rock-breaking source of tunnel boring machine independently developed by Shandong University which won the “China Patent Gold Award” in the 23rd China Patent Award recently announced. China Patent Award, jointly sponsored by the State Intellectual Property Office and the World Intellectual Property Organization, is the highest honor in China’s intellectual property field and the highest recognition of the level of patent technology and innovation.
The “bright spot” of Jinan doesn’t stop there. China’s patent gold award has been awarded to Jinan for consecutive three years, ranking first in Shandong Province, China.
Shandong University turns “black box” into “mirror”
“It’s like installing an’ eye’ on a tunnel boring machine to realize dynamic imaging of bad geology such as faults and fracture zones in front of the tunnel, so that the tunnel boring machine can’ explore while digging’.” For the gold award project, Liu Bin, a professor at Geotechnical Engineering Center of Shandong University, interpreted this.
As everyone knows, behind this is the technological precipitation of nearly ten years. “If there are faults, caves and other unfavorable geology in front of the excavation, which are prone to water inrush, mud collapse and machine sticking, the road header knows nothing, which may cause the delay of the construction period, or may induce major safety production accidents.” Therefore, Shandong University focuses its research and development on the key points of key technologies.
“The technical principle is similar to （that of ）bats flying at night. Sensing obstacles through elastic waves. When the roadheader breaks the rock, it will vibrate, and we will use the reflected’ wave’ to detect it. ” Introduction of Liu Bin. The technical difficulty lies in extracting effective information from complex signals and imaging adverse geology.
Innovation was born in the laboratory after tackling key problems with technology. But it takes a long time to really land in a real scene. “The complexity of the environment encountered in actual engineering is unmatched by laboratory simulation.” After hundreds of repeated experiments, the R&D team constantly tested, upgraded and improved the “new technology”, and finally put the technical achievements into practice, which provided strong support for the safe construction of tunnel excavation.
The national grid smart technology allows the “grid” to “perform” freely.
In the list of Chinese patent awards, State Grid Intelligent Technology Co., Ltd. from Jinan can be said to be a frequent visitor. Relying on scientific research projects that seize the commanding heights of innovation and tackle high-value patents, we have won 1 gold award and 2 silver awards in recent 3 years.
The gold-winning project of “Robot System and Method for Washing Substation with Electrified Water” enables the “substation” to “perform freely”. Substation is the heart of power grid and plays a key role in the reliable operation of power system. Due to the influence of the environment, the surface of the equipment in the open-air substation is often polluted and deposited for a long time, which is prone to pollution flashover, resulting in short circuit of the system and even large-scale power outage.
How to thoroughly solve the problem of dirt cleaning of substation equipment without power failure? State Grid Intelligent Science and Technology Corporation has successfully developed a robot system for electrified water washing of substation equipment, which can realize the robot’s independent perception of the working environment, automatic execution of the working process and intelligent decision-making of the working process. It is the first time at home and abroad to complete the electrified work of substation equipment in dense and strong electromagnetic environment for water washing.
The same gold medal was awarded by Bloomage’s project “Preparation of oligomeric hyaluronate by enzyme digestion, the obtained oligomeric hyaluronate and its application”. The project successfully broke the technical barriers of low hyaluronidase activity, high cost and difficulty in mass production of oligomeric hyaluronic acid. The application and landing of the patented technology of “enzyme digestion” makes the global hyaluronic acid industry upgrade see the future.
These innovations represent the high level of scientific and technological innovation in Jinan, and they have also accumulated a strong power for Jinan to promote industrial transformation and upgrading.
“Jinan Patent” is abounded with good policies.
Winning the Chinese patent award is a dream for research institutes and enterprises. Why did Jinan win the China Patent Gold Award in succession? The answer is that Jinan has created a superior environment for intellectual property rights so that innovation can be continuously realized.
“In response to the high-quality orientation requirements of China Patent Awards, we actively help universities, institutes and science and technology enterprises to lay out the invention patents of key core technologies in advance, and conduct high-level screening of intellectual property achievements.” The relevant person in charge of Jinan Market Supervision Bureau (Municipal Intellectual Property Office) said.
Through strengthening policy incentives, let the core technology be “created”. Jinan has introduced a series of intellectual property policies to increase the vitality of enterprises, get benefits and enjoy dividends, and granted a maximum of 1 million yuan/item for high-value patent portfolio projects with large scale, reasonable layout, and supporting and guaranteeing industrial development and international competitiveness; For those who have won the China Patent Gold Award and China Design Gold Award, they will be awarded a maximum of 1 million yuan/item and 200,000 yuan/item respectively.
By cultivating high-value patents, the quality of patents can be improved. Jinan will build a high-value patent pool around key core technologies, set up an intellectual property advantage demonstration enterprise library, focus on warehousing cultivation of intellectual property intensive enterprises, and build a number of advantageous demonstration enterprises with skilled application of intellectual property system and strong core competitiveness; establish and improve the intellectual property counseling mechanism of listed companies, implement the actions to enhance the capacity of small and medium-sized micro-enterprises, and cultivate a number of high-tech enterprises with intellectual property advantages.
By building a transfer and transformation platform, patents can be turned into achievements. Jinan will support colleges and universities to carry out targeted innovation activities around the demand of Jinan’s industrial development, solicit the core technical difficulties, pain points and technical problems that enterprises urgently need to solve, publish the list to the public, and form a consortium of enterprises and colleges and universities to conduct research; set up 12 high-value patent cultivation centers, promote order-based R&D and put-in innovation, realize the reasonable matching of demand resources, and guide the patent achievements of colleges and universities to make directional transformation for enterprises. In recent three years, the number of intellectual property rights transfer licenses in Jinan has reached more than 10,000 times.
