Small intelligent gateway device for Internet of Things
PendingCN121814498ASmooth circulationReduce the temperatureGas treatmentDispersed particle filtrationIntelligent NetworkAir pump
The invention relates to the field of Internet of Things, in particular to a small intelligent gateway device of the Internet of Things. The invention provides the small-sized Internet of Things intelligent gateway device which can accelerate air circulation to improve the heat dissipation efficiency, can adsorb moisture and dust in air and prolongs the service life of the gateway. The invention discloses a small-sized intelligent gateway device for the Internet of Things, and the device comprises a pedestal, a gateway housing, a gateway mainboard, and the like. The base is fixedly connected with a gateway shell, and the gateway shell is fixedly connected with a gateway mainboard. An operator starts an air pump, the air pump exhausts air into a gateway shell, the air takes away heat generated by a gateway mainboard, the temperature of the gateway mainboard is reduced, the gateway mainboard can work continuously, then the operator starts a servo motor, an output shaft of the servo motor rotates to drive two sets of swing plates to swing in different directions in a reciprocating mode, and the two sets of swing plates swing in different directions. Therefore, air circulation in the gateway shell is smoother, and the air takes away heat generated by the gateway mainboard more quickly.

A fatigue testing device for high temperature alloy sealing springs for aircraft engines
ActiveCN119246290Bensure safetyensure reliabilityMachine part testingMaterial strength using repeated/pulsating forces
The present invention discloses a fatigue test device for a high-temperature alloy sealing spring for an aero-engine, which relates to the technical field of spring fatigue testing, and aims to solve the technical problem that the test content of the existing fatigue testing machine is relatively single, and it is difficult to perform fatigue testing on the torsional force and bending force to which the spring is subjected. The device comprises a workbench, a push-pull assembly and a reciprocating drive assembly are arranged on the top of the workbench, a positioning assembly is arranged between the push-pull assembly and the reciprocating drive assembly, and an adjustment assembly is arranged at the bottom of the workbench. The reciprocating drive assembly is used to apply a reciprocating torsional force or a reciprocating bending force to the test spring, and perform a torsional force fatigue test or a bending force fatigue test on the test spring. The present invention has the advantages of being able to perform elastic fatigue test, torsional fatigue test and bending force fatigue test on the test spring respectively, and simulating the tensile, compressive, torsional and bending forces that the test spring may be subjected to in actual applications.

A device for the restoration and management of aquatic ecosystems
ActiveCN120157203BControl swing amplitudechange swingShaking/oscillating/vibrating mixersTransportation and packagingAquatic ecosystemReciprocating motion
This invention relates to the field of water treatment technology and provides a device for the restoration and treatment of aquatic ecosystems. The device includes a chemical tank, a float, and a propeller, and further comprises: a support assembly, a swing frame, a dual-output shaft motor, a pusher cylinder, a reciprocating disc, a reciprocating arm, a C-shaped rod, an inner shaft, a rotating plate, and a telescopic plate; a controllable chemical delivery assembly, which is also connected to the output end of the dual-output shaft motor. When the dual-output shaft motor is started, the swing frame swings back and forth, and the reciprocating arm pushes the reciprocating disc to reciprocate within the pusher cylinder. Simultaneously, the dual-output shaft motor drives the controllable chemical delivery assembly to extract the chemical from the chemical tank and controllably deliver it to the inner center of the pusher cylinder. This invention combines reciprocating motion with chemical delivery technology, and achieves efficient and flexible treatment of large areas of water through the float and propeller, significantly improving the effect of aquatic ecosystem restoration.
