Impact reduction protection structure for space camera explosive bolt unlocking device
PendingCN119308970AGuaranteed dynamic stiffnessImprove dynamic stabilityNon-rotating vibration suppressionStands/trestlesClassical mechanicsMechanical engineering
The invention relates to an impact reduction protection structure for a space camera explosive bolt unlocking device, belongs to the technical field of space optical remote sensing, and solves the problem that an existing space camera explosive bolt unlocking device cannot give consideration to impact load, explosive bolt unlocking reliability and overall dynamic rigidity of a space camera. The structure mainly comprises an explosive bolt force transmission path passive control assembly, an adjustable elastic impact reduction assembly and a medium-high frequency impact response attenuation assembly. The explosive bolt top end protection cover and the explosive bolt tail end protection cover are arranged on the explosive bolt in a sleeving mode, and the high-K-value laminated spring arranged in the explosive bolt top end protection cover and the medium-high frequency impact response attenuation assembly arranged on the top of the explosive bolt top end protection cover are combined, so that energy generated when the explosive bolt is unlocked can be effectively absorbed; the influence of medium-high frequency impact response generated when the explosive bolt is separated on the space camera is reduced, meanwhile, the unlocking reliability of the explosive bolt and the dynamic rigidity of the space camera are guaranteed, and the applicability is high.

A thin and high-voltage air-core reactor and method
ActiveCN114758860BOptimize the bottom connection methodreduce noiseTransformers/reacts mounting/support/suspensionTransformers/inductances coolingThermodynamicsMechanical engineering
The present invention discloses a thin and tall high-voltage hollow reactor and method, comprising a reactor body and heat dissipation fins arranged on the outside of the reactor body for heat dissipation, wherein an upper star frame is arranged at the upper end of the reactor body, and the lower end of the reactor body is connected to a heat dissipation component for accelerating the air flow outside the heat dissipation fins to achieve heat dissipation through a buffer; the buffer comprises an upper base plate for connecting the bottom of the reactor body, and a lower base plate is arranged below the upper base plate. The present application is designed to address the drawbacks of the existing device, optimizes the connection method of the bottom of the reactor, adopts modular connection and fixation, and improves the connection efficiency. The buffer here can also effectively absorb energy, thereby reducing the noise generated when the reactor is working and increasing the service life. In addition, air expansion can be used for initial cooling, and physical evaporation cooling is combined at the same time to effectively improve the heat dissipation effect.

Fire hydrant casting with good corrosion-resistant effect
ActiveCN224150277UAvoid unstable installationavoid damageNon-rotating vibration suppressionValve members for absorbing fluid energyStructural engineeringMechanical engineering
The utility model discloses a fire hydrant casting with a good corrosion-resistant effect, which comprises a hydrant body, a valve pipe is arranged on the outer side wall of the hydrant body, a valve cover is arranged at one end of the valve pipe, the upper end of the hydrant body is detachably connected with a hydrant cover, the inner wall of the valve pipe is fixedly connected with a buffer mechanism, and the outer wall of the hydrant body is fixedly connected with a protection mechanism. A connecting flange is welded to the lower end of the hydrant body. Through the arranged buffer mechanism, the equipment can avoid the problem of unstable installation of the water pipe, the fire hose is generally directly rushed out through the valve pipe after water is discharged, the valve pipe still has large initial impact force when water is discharged, the external water pipe is impacted, and then the discharged water is in contact through a buffer disc and a flow port, so that the water pipe is prevented from being damaged. The buffer disc is stressed to drive the buffer cylinder to slide; and through the arranged protection mechanism, the equipment can effectively prevent external sundries from invading, so that the fire hydrant casting is protected against pollution and damage, and in practical application, the protection plate can resist large impact force.
