The utility model provides a kind of valve group and compressor of miniaturization reciprocating compressor, it is related to compressor field, to the problem that the temperature of existing small compressor cylinder head is too high, gas flow resistance increases and leads to efficiency reduction, by the offset structure of valve plate on the valve plate subassembly suction hole, enlarge suction valve port flow area, reduce suction resistance, reduce the pressure loss and friction heat in suction process, to reduce suction overheating, from the source to relieve cylinder head overheating problem, allow to adopt smaller size cylinder hole, meet the demand of compressor miniaturization, the valve tongue both sides of suction valve piece are provided with contraction part to form waist, exhaust hole is arranged between two sides waist, adapt to the compact space of miniaturization valve group, suction muffler outlet and cylinder cover keep apart, leave gap, cut off the heat conduction path between cylinder cover and suction muffler, form heat insulation, reduce suction overheating, reduce cylinder head temperature benign cycle, improve miniaturization reciprocating compressor efficiency.

The utility model discloses a kind of biodegradable material mixing devices, including stirring frame, the top end of stirring frame is connected with protective device, protective device includes control sleeve, connecting sleeve, connecting rod, clamping groove, configuration groove, configuration plate, clamping block, configuration block, linkage sleeve, control block, connecting spring, control groove and storage groove, clamping groove is opened in the outside of connecting rod, configuration groove is opened in the inside of connecting sleeve, clamping block is connected with the inner wall of storage groove by connecting spring, configuration block is connected in configuration plate one side, control block is set in the outside of linkage sleeve, control groove is opened in the inside of control sleeve, storage groove is opened in configuration block, connecting sleeve outside is provided with locking mechanism, locking mechanism includes horizontal plate, vertical plate, locking sleeve, movable groove, movable plate, fixed block, locking spring and locking block, three horizontal plates are connected in the side of locking sleeve by vertical plate, the structure stability after threshold value is adjusted is ensured while the utility model realizes the flexible adjustment of overload protection threshold value, ensure that mixed work can be stably carried out.

The utility model discloses a kind of connection structure of centrifugal fan volute and motor, including volute, volute side fixed connection damping component, the side of damping component away from volute is equipped with suction component, part structure of the suction component is inserted into volute and penetrates damping component, one is directly blocked vibration energy along the path of linear penetration rubber layer, avoid energy direct transmission;Two are forced vibration wave at the interface of staggered sheet and rubber repeatedly occurs reflection and scattering, significantly improve the dissipation efficiency of vibration energy, to further weaken vibration transmission intensity.

The utility model belongs to the technical field of energy storage, and relates to an energy storage box and an energy storage system.The energy storage box comprises a first box body and a second side plate, at least one battery module is contained in the first box body, and the first box body comprises a first side plate; the second side plate is sealed on the side, provided with the anti-explosion valve, of the battery module, the second side plate and the first side plate are spaced to form an exhaust space, the second side plate is provided with an avoiding hole communicated with the exhaust space, and the anti-explosion valve faces the avoiding hole. According to the technical scheme, when thermal runaway happens to the battery cells, generated smoke can be rapidly collected into the exhaust space through the avoiding holes, gas-electricity separation is achieved, the technical effect of gas-electricity separation can effectively prevent single-point thermal runaway heat and smoke from being directly transmitted to the adjacent battery cells, and the risk of chain reaction is reduced; in addition, due to the exhaust space, smoke generated by thermal runaway can be safely guided and exhausted, and the safety of the energy storage box and the overall reliability of the system are further improved.

This invention discloses a high-pressure-resistant power battery protective shell based on a multi-dimensional honeycomb structure, relating to the field of power battery protection technology. It includes an upper protective cover, with side plates fixedly connected to both ends of the upper protective cover via fixing mechanisms. The two side plates are arranged opposite each other and enclose a cell-accommodating cavity. A honeycomb pressure-resistant mechanism is provided on the side of the upper protective cover facing the cell-accommodating cavity. At least two sets of symmetrically distributed lifting mechanisms are provided on the outer sides of both side plates. The multi-dimensional gradient composite honeycomb structure achieves high pressure and impact resistance protection, while also possessing flame-retardant, heat-absorbing, and heat-dissipating properties. This solves the problems of insufficient pressure resistance, single protective function, and poor installation adaptability of traditional power battery protective shells, significantly improving the safety and stability of power battery use.

This invention discloses a high-precision grinding system for the tip of a workpiece, belonging to the technical field of grinding systems. It includes an operating table with two symmetrical side frames fixedly connected to its top; a multi-dimensional clamping assembly positioned on the upper and lower sides of the operating table; a vision-sensing grinding positioning assembly positioned on top of the operating table; and a floating grinding head assembly positioned behind the vision-sensing grinding positioning assembly. The multi-dimensional clamping assembly provides stable clamping of the workpiece during grinding; the vision-sensing grinding positioning assembly achieves truly flexible intelligent manufacturing and compares the actual grinding effect with standard requirements, realizing integrated processing and inspection; the floating grinding head assembly effectively prevents impact force from being directly transmitted to the three-axis motion system and the workpiece surface.
