The present invention relates to an aerial safety dolly and modular rigid rail system designed for construction and maintenance personnel working at heights, enabling continuous, smooth and fail-safe operation for fall arrest, rope travel and descent. The aerial safety dolly has a connecting arm, a clamp body and a main frame operatively interfacing with a rail engagement mechanism movable between a rail engagement position to engage a rigid rail and a disengagement position to disengage the rigid rail. The rail engagement mechanism can include an integral pivoting arm that simultaneously closes inward to engage the rigid rail and outward to disengage the rail. Thus, the dolly can be easily and safely connected and disconnected at any location along the rigid rail.

The present application relates to a diving propeller, an angle controller and a control method thereof, in particular to a diving propeller. The diving propeller comprises a battery and a propeller, characterized in that: the propeller comprises a left propeller and a right propeller, the front part of the left propeller and the right propeller is connected with a waistband power supply battery through a left propeller power supply cable and a right propeller power supply cable respectively; the rear part of the left propeller and the right propeller is connected with a left angle controller and a right angle controller through a left angle controller connecting cable and a right angle controller connecting cable respectively; the left propeller and the left angle controller and the right propeller and the right angle controller are distributed in a left-right symmetry. Compared with the prior art, the angle controller on the leg can be used to carry out the modes of advancing, variable speed advancing, retreating, turning, and turning in place, and the whole operation process only relies on the diver to control the angle between the left leg and the right leg, and does not need to be controlled by hand.

Embodiments of footwear to optimize propulsion while swimming in the water and walking on land, in particular, amphibious footwear capable of duty on land and in the water as well as versions that are optimized for predominantly use in the water for swimming. The exoskeleton amphibious footwear reduces metabolic demand of walking and swimming while also improving gait speed and swim speed. This is accomplished by assisting plantar flexion during land mode, and assisting dorsiflexion in water mode.

This invention discloses a strap-retracting device for life jackets, comprising a housing, and a strap-retracting mechanism, a rotating mechanism, and a propulsion mechanism installed inside the housing. The housing is fixed to the hem of the life jacket, and has holes for the straps to pass through. One end of the life jacket's strap is connected to the life jacket, and the other end passes through the holes in the housing and connects to the strap-retracting mechanism. The strap-retracting mechanism includes a guide shaft, a linear bearing, a bushing, a flange nut, and a strap-retracting groove. The upper part of the guide shaft has a bushing. The linear bearing is sleeved on the guide shaft, and the inner wall of the linear bearing has a slider. The outer wall of the guide shaft has a groove, and the slider is adapted to the groove. The slider can slide within the groove, thereby driving the linear bearing to move axially along the guide shaft. The beneficial effects of this invention are: the strap-retracting device of this invention structurally and functionally couples the rotating mechanism, the propulsion mechanism, and the strap-retracting mechanism, thereby realizing the strap-retracting function of the life jacket and improving the safety factor of the life jacket.

The invention discloses a waist and leg two-point fixing type underwater propulsion system based on a universal detachable tool battery, and belongs to the technical field of underwater movement auxiliary equipment. The system comprises an integrated power module which is integrated with an underwater propeller, a propeller electronic speed controller and a waterproof quick-connection interface; the two-point type torque restraining and stabilizing system comprises a main waistband rigidly connected with the power module and an auxiliary bandage connected with the bottom of the module through a flexible belt and used for fixing thighs, and the main waistband and the auxiliary bandage cooperate to restrain the equipment from rotating around the waist axis of the human body; the waterproof quick-connection interface comprises an original tool battery slide rail base and waterproof pouring sealant wrapped in all directions, so that a battery pack meeting the standard of a commercially available handheld electric tool interface can synchronously realize mechanical locking, electrical connection and waterproof sealing underwater. According to the invention, direct manual control (delay lt; according to the invention, a general battery underwater hot plug and waist and leg two-point stable structure is adopted, the problems of large response delay, anxiety in endurance, high cost and poor stability in the prior art are solved, and zero learning cost operation, infinite endurance, significant cost reduction and excellent underwater movement stability are realized.
