The invention patent began in the research project “Research on the standard device for high-voltage three-phase combined transformers†developed by Jiang Bo, an expert of Sichuan Electric Power Measurement Center of State Grid in 2007. The invention patent was declared in 2011 as a successful national invention patent in China. The invention patent is an overall detection system for the three-phase electric energy metering device of the distribution network, which solves the key technical problems of the test and analysis under the close operating conditions of the site, can restore the actual operating conditions of the site, and comprehensively detects the metering device of the distribution network, and obtains The accurate error data of the three-phase power supply system of the distribution network effectively solves the problem that only the single-phase detection and verification mode can be carried out at present, and improves the technical capability of the inspection and troubleshooting of the distribution network metering device. It is reported that the difficulty of international patent declaration in Europe and the United States is the highest in the world. The UK is a big country in Europe and the United States, and its patents are recognized by the industry. Therefore, the standards for reviewing relevant materials are particularly harsh. The invention patent was successfully applied for the national invention patent in China in 2011, and applied for the PCT patent to the International Patent Office at the end of 2011. In 2012, it obtained the international stage review conclusion issued by the International Patent Office with “newness and creativityâ€; At the national stage of the British patent, in October 2016, it was finally approved by a British expert's e-mail question, and in December 2016 it was successfully announced and authorized by the UK Intellectual Property Office.

It was learned from the State Grid Sichuan Electric Power Company that the invention patent of the company's "on-site integrated detection system for three-phase energy metering system of distribution network" was authorized by the British Patent Office. The successful authorization of the British patent marks that China's overall detection technology capability in the distribution network three-phase energy metering system has reached the international leading level.
1. The drilling machine has high input power, high output torque and strong drilling capacity.
2. The output speed range of the drilling machine is wide, which is suitable for both engineering geological investigation and diamond core drilling.
3. The drilling machine is equipped with an open box rotator for easy operation of the orifice.
4. The utility model has an oil pressure feeding mechanism and a ball clamp type clamping mechanism at the upper end of the vertical shaft, which can improve the drilling efficiency and reduce the labor intensity of the workers.
5. The drilling rig is equipped with active drill pipe, which can realize non-stop reversing, with high efficiency, safety and reliability.
6. The drilling rig adopts the double plate normally closed friction clutch, which is flexible in opening and closing and convenient in operation and adjustment.
7. The gear box of the drilling rig adopts the structure of automobile gear box, with single handlebar speed change and interlock mechanism, which is convenient for operation.
8. The drilling machine is separated from the water pump, and the pump and the drilling machine are separately equipped with power, which can improve the output torque of the drilling machine, especially when entering the deep hole for drilling, there will be no contradiction in the use of the water pump due to the decrease of power, so as to avoid accidents in the hole.
9. The drilling rig is compact in structure, small in volume, light in weight, and the largest part is less than 100kg, which is convenient for disassembly and handling, and suitable for working in hills or mountains.
