2results about How to "Achieve height change" patented technology

This invention discloses a movable reaction wall for hybrid simulation testing, belonging to the field of hybrid simulation testing technology. It includes: multiple support columns arranged in an array, with the first end of each support column fixedly connected to an embedded part in the ground of the vibration table; multiple connectors disposed between adjacent support columns and spaced apart along the height direction of the support columns; and actuator supports, adjustable in height and disposed on the outer sides of adjacent support columns. During the simulation test, the actuator supports are connected to the hybrid simulation test actuator. This invention can be used for hybrid simulation testing and is easy to disassemble, assemble, and store, facilitating material reuse and avoiding resource waste.

The utility model relates to plant cultivation spraying system technical field especially, more particularly to a kind of lifting spraying system of plant germination growth, including cultivation module and the shower head being set in the upper cultivation module, further including the spraying support for installing shower head, spraying support is installed with the shower pipe being communicated with shower head;Further include the longitudinal support of longitudinal arrangement, longitudinal support is provided with the longitudinal adjusting structure for the longitudinal movement of spraying support;The shower head above cultivation module sprays water to cultivation module, realizes cultivation, when the height of cultivation module changes, spraying support can be moved longitudinally in longitudinal adjusting structure in longitudinal support, so that the height of spraying support changes, the shower head of installation in spraying support can realize height change, can be matched with the height of cultivation module, the water of spraying can be entered into cultivation module, reduce waste.
