Abstract: In one embodiment, an apparatus includes: a frame to support a plurality of electric vehicle (EV) chargers; the EV chargers, each including or coupled to a dispenser to provide charging power to at least one EV; and at least one actuator coupled to at least a portion of the frame. In response to a flooding condition in a vicinity of the apparatus, the at least one actuator can raise the EV chargers to a raised position.

Abstract: The disclosure provides a fracturing isolation sleeve for a wellhead assembly including a fracturing adapter and tubing head. In at least one embodiment, the sleeve can telescopic to different lengths to fit different assemblies without necessitating switching the sleeve or portions thereof. The sleeve can be coupled to the wellhead assembly by threaded and non-threaded connections. The sleeve upper portion can be threadably engaged with the wellhead assembly, and/or the sleeve lower portion can be threadably engaged with a packoff bushing rotationally coupled to the wellhead assembly through an anti-rotation mechanism. Further, the sleeve can include a retaining nut to be threadably engaged with the wellhead assembly without necessarily rotating the sleeve upper or lower portions. The sleeve can be also coupled with the wellhead assembly through a mandrel coupled to the sleeve having an actuating cam surface to actuate a lock ring with the wellhead assembly.
