摘要： A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.

摘要： A reinforcing assembly includes one or more longitudinally-extending bars having a first end and a second end opposite the first end, multiple first working members, and multiple second working members. Each working member is independently connected to at least one of the one or more bars and extends away from the one or more bars. The first working members are oriented diagonally with respect to a longitudinal axis extending along the one or more bars and are connected along a first continuous portion of the one or more bars. The second working members are oriented diagonally with respect to the longitudinal axis and are connected along a second continuous portion of the one or more bars. The first working members extend from the one or more bars away from the second working members. The second working members extend from the one or more bars away from the first working members.

摘要： Pneumatically supported towers for low gravity applications are disclosed herein. In one aspect, an inflatable tower for use in vacuum environments can have a membrane configured to support a load when inflated with an inflation gas to a pressures less than 100,000 pascals and greater than 0.01 pascal. The inflation gas can be chosen to have a sufficiently low boiling temperature at the inflation pressure of the membrane that the gas will not condense to a liquid or solid within a defined range of temperatures in which the tower is designed to operate. The membrane can be configured to be packaged for transport in deflated condition and rolled onto cylinders from which the membrane can be later unfurled and inflated as part of the tower inflation process. The membrane can be further configured to progressively inflate beginning at a bottom or lowest level of the membrane during the tower inflation process. The membrane can be divided into a plurality of compartments by one or more diaphragms containing valves configured to regulate flow of the inflation gas between the compartments.

摘要： The invention relates to the field of automobile elevators. An upright post structure is provided, wherein the upright post structure is a polygonal columnar structure formed by bending a plate, the upright post structure comprises a back plate, both ends of the back plate in a width direction vertically extend toward the same side of the back plate to form a side plate, end parts of the side plate away from the back plate extend oppositely to form a front plate, wherein the upright post structure further comprises one or a combination of various. Thus, when the upright post structure is subjected to a force in a horizontal direction, the local stress of the upright post is transferred so that the strength of the upright post is improved. The invention further provides automobile elevator using the upright post structure.

摘要： A vertical escape structure comprises an escape housing disposed in a vertical orientation and mounted to a ground to maintain structural integrity in the vertical orientation against external flooding. The escape housing includes an interior which is sealed against water entry from exterior flooding and at least one of a staircase, a ladder, an elevator, or a lift disposed in the interior of the escape housing. The vertical escape structure further comprises a connecting walkway to connect the escape housing to a building. The escape housing has a smaller horizontal footprint than the building. The walkway is severable from the building by force without damaging the escape housing to cause water entry from the exterior flooding.

摘要： A wind power generation apparatus, a tower and a method for suppressing a tower shadow effect of the tower. The tower is provided with suction through holes extending through a circumferential wall thereof, and the suction through holes are distributed in a circumferential direction of the tower; the tower is further provided with a suction apparatus, and the suction apparatus can perform suction to the suction through holes from outside to inside. With the tower and the method, when the suction through holes at a windward side are suctioned, the adverse influence of the tower shadow effect can be weakened or eliminated, a service life of a pitch varying bearing can be prolonged, a noise can be reduced and a wind energy utilization coefficient can be improved. When the suction through holes at a position of a bypassing flow detachment are suctioned, vortex-induced vibrations can also be suppressed.

摘要： A floating body device for suppressing vibration of enclosure includes a floating body surrounding the enclosure and an excitation device which can excite the floating body to float up and down. The excitation device includes a tether connected to the floating body to prevent the floating body from falling off from the enclosure. When the floating body floats up and down, an airflow boundary layer on an outer wall of a tower can be destroyed, and a cause of vortex-induced vibration can be directly suppressed. In addition, a change of an aerodynamic configuration is obtained. The up and down floating of the floating body disrupts both upper and lower sections of a nearby flow field, thus weakening a combined action thereof, thereby preventing the vortex induced vibration of the tower.
