A bird deterrent device based on wide-area ultrasonic bird-repelling environments
This utility model discloses a bird-repelling device based on a wide-area ultrasonic wave-based environment that deters birds, belonging to the field of environmental bird-repelling technology. It includes a main body box and ultrasonic modules. Two sets of ultrasonic modules are fixedly installed inside the main body box. A bird-repelling component is installed on the top of the main body box, and a fixing component is installed on the back of the main body box. This utility model utilizes the designed bird-repelling component, which, when blown by wind, rotates a push plate, causing the ribbons to flutter and reducing the likelihood of birds nesting in the area. Furthermore, the reflections from different surfaces create a multi-directional, more chaotic glare effect, enhancing the bird-repelling effect. Combined with the internal connecting ropes and connecting plates that generate knocking sounds to drive away birds, the staggered frequency ranges of the sounds produced by each connecting plate can cover as many sound frequencies as possible, creating an irregular sound effect. The combined use of multiple bird-repelling methods greatly improves the bird-repelling effect.

Rear main speed reducer assembly
ActiveCN224093790UImprove driving effecteasy to controlGearing detailsReduction driveElectrical battery
The utility model relates to the technical field of automobile speed reducers, in particular to a rear main speed reducer assembly which comprises a rear main speed reducer (1). A torque manager (2) and an expansion structure are respectively arranged on the rear main speed reducer (1); the torque manager is installed on the rear main speed reducer, the driving performance of the vehicle can be optimized, the control stability, the traction capacity and the escape capacity are enhanced by dynamically adjusting the torque transmitted to the rear wheels, meanwhile, better vehicle control is provided during emergency avoidance or rapid steering, and driving safety is ensured. In addition, fuel economy or battery endurance of the electric vehicle can be improved, driving experience is improved, and the electric vehicle can adapt to different driving modes so as to meet diversified driving requirements. The expansion structure provides different schemes for a rear suspension structure of the rear main speed reducer. Therefore, the universality of the device is effectively improved.
