This invention provides a large-scale offshore precast pile positioning fixture and its usage method. The precast pile positioning fixture includes a positioning pile, a pile driving positioning fixture, and a layout fixture. The pile driving positioning fixture is rectangular, and adjacent sides are connected by corresponding layout fixtures, which in turn are connected to their corresponding positioning piles. In this invention, the simple layout fixture determines the positions of the two sides of the pile driving positioning fixture. Because the pile driving positioning fixture itself is rectangular and reinforced with reinforcing rods, its strength and stability are ensured. Thus, by positioning two adjacent sides of the rectangular frame with two positioning fixtures, the pile driving positioning fixture can be quickly positioned. In this invention, the pile gripper can be integrated or separate. Separate positioning rings can be opened and locked using spring locks, allowing for easy disassembly and extraction of the pipe pile.

This application belongs to the field of hydro-generator installation and discloses a stator core slot clamping device for hydro-generators with measuring function. It includes a support cylinder and an insert block disposed at the front end of the support cylinder. The first end face of the insert block has outwardly extending lugs on both sides, and the opening formed by the lugs and the first end face mates with the slot opening of the hydro-generator stator core slot. A measuring scale is provided on the outer side of the insert block. A pressure sensor is provided on the inner side of the first end face of the insert block. A threaded through hole is provided in the middle of the insert block, and a screw rod is provided inside the support cylinder. The screw rod passes through the threaded through hole and is threadedly connected to the insert block. This reduces the difficulty of clamping the stator core wires in the hydro-generator and improves installation efficiency. The pressure sensor, in conjunction with the measuring scale, can determine whether the stator wires are clamped firmly and tightly against the bottom surface of the core slot, solving the problem that the stator wires are not easily fully lowered to the bottom of the stator core slot during installation, thus affecting the installation of the slot wedges.

This invention discloses a hybrid powertrain transmission device coupling an engine and an electric motor, including an engine, a generator, and a drive motor. A rotational transmission mechanism is provided between the drive motor and the wheels. A heat dissipation protection component is provided on the gearbox of the rotational transmission. The heat dissipation protection component includes a heat dissipation fin plate disposed inside the gearbox, an air duct communicating with the outside of the gearbox, and a heat dissipation fan and a lubricant spraying assembly disposed inside the air duct. The air duct is connected to the airflow channel of the heat dissipation fin plate. When the heat dissipation fan is working, the airflow generated flows through the heat dissipation fin plate to dissipate heat inside the gearbox. At the same time, the generated air pressure drives the lubricant spraying assembly to spray lubricant at the gear meshing position. In operation, the invention enables air to continuously flow through the heat dissipation fin plate by turning on the heat dissipation fan, thereby dissipating heat from the gearbox cavity and protecting the gears.

The application discloses an underwater robot grabbing device with a buffer structure and belongs to the underwater robot field.The underwater robot grabbing device comprises a grabbing dynamic guide structure, a multifunctional buffer matching and adjusting claw structure, a power module, a driven transmission module and other equipment which are connected with each other.The underwater robot grabbing device is designed in cooperation with the grabbing dynamic guide structure and the multifunctional buffer matching and adjusting claw structure, so that the underwater robot grabbing device is convenient to use underwater, and a multidirectional adjustable claw is formed, so that the underwater robot grabbing device is convenient to adjust the different volumes and different clamping angles underwater, and thus the underwater grabbing is facilitated.In addition, the underwater robot grabbing device is designed in cooperation with the reciprocating positioning derivation module and the buffer claw module, so that the underwater robot grabbing device is convenient to reciprocally impact the position which cannot be clamped and fixed by the underwater hard object, so that the positioning nail is punched into the interior, the underwater robot grabbing device is convenient to be applied to the underwater ore sample grabbing, and the design of the buffer structure avoids the impact from directly acting on the whole device, and the service life is facilitated to be prolonged.
