It was learned from the Yantai Maritime Department that the Ministry of Communications will invest 39.5 million yuan to renovate and expand six radar stations and one ship traffic management center in the Yantai Sea area of ​​Huanghua Sea to realize seamless monitoring of ships and improve ship monitoring capability and emergency in the sea area. Reaction level.
According to reports, according to the requirements of the Ministry of Communications, the Yantai Maritime Department will build four radar stations in Beishan Island, Dazhushan Island, Laobei Mountain and Lumjiao in Changshan Islands, Penglai and Longkou, and transform the North Changshan radar. The station still uses the newly built Zhizhidao radar station, and at the same time sets up the ship traffic management center, and finally forms a new layout of centralized monitoring and management of sea traffic dynamics composed of six radar stations and one ship traffic management center.
It is understood that the system engineering is an integrated management platform. Through information integration and remote transmission, it can carry important routes from Yantai to Dalian, Penglai to Lushun, Penglai to Long Island, as well as Laotieshan Waterway, Changshan Waterway, Dengzhou Waterway and Yantai. Vessels in various ports of the jurisdiction shall carry out seamless monitoring and comprehensive coverage; on the basis of further improving the ship monitoring capability of the Huangyanhai Yantai sea area and improving the port operation efficiency, the collision of ships, stranding of rocks and mis-entry into the culture shall be minimized. District and other accidents. At the same time, since all ship dynamic information in the jurisdiction can be displayed very intuitively on the radar display, in case of danger, the maritime department can effectively organize the ship and surrounding emergency forces in the incident waters, and participate in the search and rescue operation in the first time. Effectively improve the speed and level of emergency response in the jurisdiction. The entire project construction is an integral part of the National Water Transportation Safety Supervision and Rescue System Layout Plan.
The Yantai Maritime Safety Administration has a total area of ​​about 21,000 square kilometers. There are more than 70 large and small islands. On the 910-kilometer coastline, there are 10 large and small ports. The average annual commercial ship flow is nearly 200,000. It has navigation resources. It is characterized by rich, navigational environment, large ship flow, high passenger density, variable weather conditions and dangerous conditions. It is the key area of ​​the “four districts and one line†identified by the Ministry of Communications.
Drill chuck is by drilling collet, elastic dial ring, connecting piece, the back cover. In drill collet, its axial positioning is implemented using the connection piece, upon jack, via the circumference of a circle in the elastic dial ring under the action of internal thread axial movement, under the action of a precise automatic centering and clamping tool, when you are working with different drilling tools need to adopt such as center drill, drill, reamer, tap drill chuck, can loosen the positioning screw, turn the segment to the desired location, fastening positioning screw, realize the drill chuck the movement of the transfer.
The drill chuck is one of the main parts of electric tool industry and machine tool industry, widely used in electric drill, drilling machine. Chuck is connected with the tool, is used to clamp the handle type tool accessories. The drill and connection with threaded connections and taper connection in two ways. Threaded connection is mainly used on an electric hand drill, cone connection is mainly used for drilling machine drill chuck from structure can be classified as type wrench and keyless. Spanner drill chuck wrench to tighten the wheel needs, mainly used in machine tool industry, such as drill and drill. Hand drill chuck set to hold on and tighten the collet, mainly used for electric drill. Spanner drill chuck as by pulling wheel to tighten the collet and a pulling wheel is a with an extension arm of bevel gear, so in the process of screwing can serve to increase the role of input torque, so chuck clip clamping force is too large
