Emergency help signal panoramic projection device, method and terminal
ActiveCN121768121Bimprove intelligibilityIncrease the chance of being rescuedPicture reproducers using projection devicesElectric transmission signalling systemsPanoramaRadiology
The application belongs to the technical field of emergency help equipment, and provides an emergency help signal panoramic projection device, method and terminal, the device can continuously detect the spatial posture and rotating motion state of itself through the environment positioning module, generate corresponding posture data and direction data, the control module can obtain the data and determine the real-time projection pointing angle of the device, and then when the device rotates, the projection control instruction corresponding to the real-time projection pointing angle is generated and sent to the image projection module, so that the image generation unit in the image projection module drives the corresponding rotating transformation of the help image, and the light source in the image projection module irradiates the help image to project the visual help signal which is right and complete. The scheme realizes omnidirectional controllable intelligent projection, can make the help signal cover all directions, at the same time ensures that the projected image can be clearly observed, is more easily identified by the rescuer, reduces the delay caused by signal blur, and improves the probability of being rescued by the help seeker.

Tap water pressurizing and pressure stabilizing device
ActiveCN224213431Ureduce outputExtended service lifeService pipe systemsWater mainsAutomatic controlLoop control
The utility model discloses a tap water pressurizing and pressure stabilizing device, which relates to the field of water supply equipment and comprises a water collector, a water distributor, a pressure stabilizing tank and an intelligent control system, the water inlet end of the water collector is communicated with a water source, and the water outlet end of the water collector is connected with the water inlet end of the water distributor through a water delivery pipeline with a booster pump. The water outlet end of the water segregator is connected with a plurality of distribution branches, the water segregator is connected with the surge tank, a constant-pressure pipe is connected between the water collector and the water segregator, a constant-pressure device is arranged on the constant-pressure pipe, a pressure sensor is arranged on the water segregator, the intelligent control system is provided with a man-machine interaction panel, and according to signals of the pressure sensor, the intelligent control system controls the constant-pressure device and the pressure sensor. Starting, stopping and rotating speed of a booster pump are controlled and adjusted, and the target pressure value of water pressure is maintained; through the synergistic effect of the constant pressure device and the closed-loop control system, water pressure fluctuation and water vortex are eliminated, the stability of water pressure is guaranteed, the pipeline is protected against impact damage, full-automatic control is achieved, the requirement for manual intervention is lowered, and the reliability of the system is improved.

Fire door resistance to water spray impact tester
ActiveCN224303475UProtected from impact damageEasy to adjust and change the diameterMaterial strength using single impulsive forceWater flowScrew thread
The utility model relates to fire fighting equipment detection technical field discloses a kind of fire door anti-spraying water impact tester, including fire hose, the inside left side of fire hose is fixedly connected with round, the inside fixedly connected with cylinder in round, the outside sliding connection of cylinder has slip ring, the outside right side of slip ring is fixedly connected with spring a.In the utility model, first, slip ring is pushed back under the action of water flow pressure and is slid on cylinder to round inside, let water flow pass smoothly, when water flow appears backflow trend, slip ring will be quickly reset under the action of spring a elasticity, form tight seal, to block reverse water flow, simultaneously, when rotating handle on top layer moves down, water flow resistance increases by thread transmission to drive pressing plate to move down, inside flow cross-sectional area reduces at this time, water flow resistance increases;Conversely, the extrusion force of water decreases, water pressure reduces, it is convenient to adjust and change hose pass diameter, promote the progress of experiment.

Hammer crusher gear shock absorbing mechanism
The utility model relates to hammer crusher technical field especially is a kind of hammer crusher gear damping mechanism, including hammer crusher, the driving shaft of being movably installed in hammer crusher and driving motor, the output end of driving motor is fixedly connected with driven shaft, and driven shaft is detachably installed with no. Two elastic bushings, the driving shaft is detachably installed with no. One elastic bushing, transmission assembly is jointly provided on one elastic bushing and no. Two elastic bushings. The hammer crusher gear damping mechanism of the utility model, by setting detachable elastic bushing of multilayer structure on driving shaft and driven shaft, and combining with belt drive, the strong impact vibration generated when hammer crusher works is effectively absorbed and isolated, high-damping intermediate layer can significantly dissipate vibration energy, substantially reduce the dynamic load transferred to driving motor and transmission system, prolong the overall service life of equipment, improve the stability and reliability of operation.
