The invention discloses a seismic exploration submarine cable recycling and coiling device, which is applied to collecting underwater cables after seism in areas such as lakes, rivers and oceans in oil seismic exploration. The seismic exploration submarine cable recycling and coiling device is characterized by mainly comprising a bow crawler-type cable collecting machine and a hoisting cable coiling device, wherein the bow crawler-type cable collecting machine is fixed to the deck of the bow of a cable boat; the hoisting cable coiling device is longitudinally fixed to the center of a working area of the cable boat; a submarine cable is inserted into the bow crawler-type cable collecting machine through a cable guide slot and is posited on a rubber track and between a driven pinch roller and a driving pinch roller; and then the submarine cable is inserted between a driven suspend roller and a driving suspend roller of the hoisting cable coiling device. The invention has the advantages that the seismic exploration submarine cable recycling and coiling device can normally recycle cables under the six-grade oceanic condition; the cables are recycled by machines under the assistance of staff, and the maximum 50-meter depth mechanical cable recycling operation is realized; 40 to 50 percent of the conventional cable recycling operators are saved, and the labor intensity of the cable recycling operators is reduced to the greatest extent; and the cables are prevented from being damaged and the damage rate of the cables is reduced.

The invention relates to the technical field of new energy vehicles, and discloses an electric vehicle with an automatic protection function during charging. The electric vehicle comprises a shell, asupporting base is fixedly mounted at the bottom of an inner cavity of the shell, and a battery case located in the inner cavity of the shell is fixedly mounted at the top of the supporting base. Electrode protection boxes are fixedly mounted on both sides of the battery case, and the other sides of the electrode protection boxes are fixedly connected with the inner wall of the shell. Electrode blocks are fixedly mounted at the inner cavities of the electrode protection boxes. According to the electric vehicle with the automatic protection function during charging, fixed handles are loosened by moving a moving handle, and an entire moving wire is displaced downwards, so that conductive blocks are separated from clamping connecting conductive blocks, the driving of the vehicle is disconnected, and the vehicle cannot be driven in the charging process; and the problem that the vehicle is driven to damage a charging device due to the fact that a driver often forgets that the vehicle is being charged in a long charging process, and the safety of the electric vehicle is increased.

The invention provides a stamping-type molding stick-making machine comprising a power device, an extruding device and a forming mold, all of which are connected in sequence and arranged on a base; the stamping-type molding stick-making machine further comprises a lubricating and cooling device; the lubricating and cooling device comprises an oil tank, an oil pump and a flow adjusting controller, all of which are connected in sequence; the flow adjusting controller is divided into a plurality of branches connected to lubricated and cooled parts; and the lubricated and cooled parts are connected with the oil tank to form a circulating oil path. The machine has the following beneficial effects that the purpose of multi-oil-path synchronous lubrication can be fulfilled, the friction heat of a moving part can be reduced by oil solution cycling, the lubricating and cooling effects are good, the apparatus is worn slowly, and the problems of high temperature and wearing which frequently occur in the apparatus can be solved well. Meanwhile, the product is small in size, low in energy consumption, high in yield and production efficiency and capable of compacting materials twice, automatically adjusting the feeding amount of the materials, achieving automatic protection function and fulfilling the functions of automatic warning and stopping when in fault.

The invention relates to an overload protective system of a drilling machine. The overload protective system comprises a rotary motor, a feeding cylinder, a motor forward pressure pipeline and a drilling cycle system pressure pipeline, wherein the rotary motor is connected with the motor forward pressure pipeline, and the feeding cylinder is connected with a feeding pressure pipeline. The overload protective system is characterized in that a hydraulic sequence valve and an external control reversing valve are serially connected to the feeding pressure pipeline, a control port of the hydraulic sequence valve is connected with the motor forward pressure pipeline, and a control port of the external control reversing valve is connected with the drilling cycle system pressure pipeline. The overload protective system of the drilling machine, provided by the invention, has a simple structure and is reliable; and drilling accidents of the drilling machine in a working process are avoided, the overload of the drilling machine can be prevented, and the automatic protection function is achieved.
