Damping insole applicable to low-frequency whole-body vibration of hydropower station

Abstract

The invention discloses a damping insole applicable to low-frequency whole-body vibration of a hydropower station and belongs to the technical field of whole-body vibration protection of the hydropower station. The damping insole is formed by a contact layer, a damping layer and an air cushion, the contact layer is divided into a sole area, an arch area and a forefoot area, and the edge shape of the contact layer curls inward from the edge to adapt to a shoe in shape; the damping layer is located under the contact layer and is connected with the arch area and the forefoot area of the contact layer in an adhesion manner, the edge shape of the damping layer is identical to that of the contact layer, vent holes are further formed in the position of the arch area of the damping layer, and an anti-skip structure is arranged on the forefoot area of the damping layer; the air cushion is located under the contact layer and is connected with the sole area of the contact layer in an adhesion manner. Health of an operator is protected through an individual protection mode, and problems that extensive layer of a damping pad easily leads to inconvenience in ground cleaning and an disadvantage in carrying out of maintenance work are solved.

Description

technical field [0001] The invention belongs to the technical field of whole-body vibration protection of a hydropower station, and in particular relates to a shock-absorbing insole suitable for low-frequency whole-body vibration of a hydropower station. Background technique [0002] The impact of vibration on the human body is divided into whole-body vibration and local vibration. The whole-body vibration is caused by the vibration source passing through the supporting parts of the body (foot and buttocks), and the vibration is transmitted along the lower limbs or trunk to the whole body to cause indirect vibration. Whole-body vibration may lead to damage or displacement of internal organs, changes in peripheral nerve and blood vessel function, which may cause foot pain, fatigue of lower limbs, weakened dorsal pulse of the foot, and lower skin temperature. Vibration acceleration may also cause vestibular dysfunction, resulting in Inner ear regulation and balance dysfunction...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a vibration-damping insole suitable for low-frequency whole-body vibration of a hydropower station. Its purpose is to reduce the level of low-frequency whole-body vibration in the hydropower station's work site through an individual protection method, thereby effectively protecting the occupational health of the workers and solving the problem of the vibration-damping pad in the hydropower station's work place. Large-scale laying will easily cause inconvenient cleaning of the ground and is not conducive to the development of daily maintenance and other work.
