The application discloses a tension type impressed current cathodic protection system, which comprises a composite cable made of a steel core aluminum stranded wire with an outer sheath, a first insulation connecting structure arranged at the upper end of the composite cable and used for insulatingly connecting the composite cable with a member to be protected, a cable branch structure arranged at the upper end of the composite cable and used for electrically connecting the composite cable with a power control cabinet, an auxiliary anode arranged on the composite cable and used for releasing current, and a second insulation connecting structure arranged at the lower end of the composite cable and used for insulatingly connecting the composite cable with a gravity foundation. The tension type impressed current cathodic protection system disclosed by the application has the advantages of light weight and low price compared with the existing composite cable copper as a power line under the same current carrying requirement, and the production processing technology of the steel core aluminum stranded wire is simplified as the steel core aluminum stranded wire only needs to be coated with a wear-resistant sheath.

The present invention relates to the field of battery module welding fixtures, and in particular to a fastening fixture for battery module laser welding, comprising a mounting platform, a left supporting slide, a right supporting slide, a battery mounting slide, a battery mounting slide drive plate, a pushing screw, a fixing block, a first tightening member, a guide support mold frame and a pressing mold frame, wherein the left supporting slide and the right supporting slide are symmetrically arranged on the mounting platform and are fixedly connected to the mounting platform. The present invention specifically designs a fixture suitable for battery module welding, which can tighten and fix the battery very accurately, in view of the problems that the battery position is not fixed during battery module welding, and the welding is prone to loose welding, the welding position deviates from the predetermined position, the welding efficiency is low and the welding yield is low.

The invention provides an extended-range engine which comprises an engine body, the engine body comprises a cylinder body and a crank case, the cylinder body comprises a left air cylinder and a right air cylinder, a left piston and a right piston are arranged in the left air cylinder and the right air cylinder respectively, a crankshaft is arranged in the crank case, and the left piston and the right piston are arranged in the crank case. The left piston and the right piston are connected to the two ends of a crankshaft through a left connecting rod and a right connecting rod correspondingly. A generator rotor is arranged on the crankshaft, the generator rotor comprises a rotor winding, and the rotor winding is arranged on a crank of the crankshaft to form a first balancing weight; and a generator stator is adaptively arranged in the machine body. The power assembly has the advantages that the rotor winding is arranged on the crank of the crankshaft to form the first balancing weight, the weight and the size of the power assembly can be reduced, the space arrangement difficulty is optimized, the driving performance of the whole vehicle is improved, and meanwhile the cost of the power assembly can be reduced; layered arrangement of the windings maximizes the line length of magnetic induction lines cut by the rotor windings, and improves the working efficiency of the generator rotor in unit volume.
