The invention discloses electromechanical damping equipment which comprises a bottom plate. Damping air bags are fixedly connected to the two sides of the top of the bottom plate correspondingly. The front surface of each damping air bag is provided with an inflation valve. The top of each damping air bag is fixedly connected with a first connection block. The top of each first connection block is fixedly connected with a first spring. The top of each first spring is fixedly connected with a squeezing block. The top of each squeezing block is fixedly connected with a supporting column. The tops of the supporting columns are fixedly connected with a top plate. By arranging the squeezing blocks and the first springs, the top plate can be easily returned to the original position in the downward-pressing process, the vibration effect of the first springs is achieved through the arrangement of the damping air bags, the damping effect is achieved through the damping air bags, the buffer effect is achieved through the cooperation of a first fixed block, a third spring, a first sliding block, a first movable rod, a second sliding block, a fourth spring, a second movable rod and a second fixed block, and the electromechanical damping equipment has the effects that adjustment is flexible and universality is improved.

The invention discloses a device for taking and placing a chaton automatically, which comprises two mechanisms for taking and placing the chaton, an up-down moving mechanism and a transmission mechanism, wherein the two mechanisms for taking and placing the chaton have the same structure and are arranged symmetrically to the axes of the device. The device can realize continuous taking and placing of the chaton in the condition of not needing complicated control; the chaton is not easy to damage when the device takes and places the chaton, and is not easy to deviate when the device places the chaton; and the device has simple structure and high reliability, and is suitable to be generally used in the ornament industry.

The invention discloses a distribution network integrated lightning protection system comprising a transformer substation, and output lines led out of three phases of outlet ports of a transformer substation transformer. Each phase of line is connected in series with an overvoltage isolator. Overhead wires are formed through lead-out of the output ends of the voltage isolators to a pole tower. Pole tower insulating cross arms support the overhead wires, and power transmission wires are fixed via multifunctional wire clamps arranged on the insulating cross arms. A wave-resistant lightning rod is installed at the top end of the pole tower. A simple and rapid grounding device is embedded in the ground of the bottom part of the pole tower so that integrated lightning protection performed on the distribution network lines and the transformer substation is realized with pole tower protection acting as the center and prevention of distribution network lightning tripping and disconnection acting as the key points. Distribution network line dedicated lightning equipment like the wave-resistant lightning rod, the insulating cross arms, the multifunctional wire clamps and the simple grounding device are organically integrated by the system so that the multilayer and three-dimensional integrated lightning protection system is constructed and realized, lightning trip-out rate and disconnection rate can be substantially reduced, and maximum matching of distribution network lightning economical efficiency and effectiveness is realized.
