An offshore wind energy system comprising a foundation having a first hollow structural element with a longitudinally extending, circumferential first wall. A cable bushing penetrates through the first wall and is arranged in the first wall. At least one cable guide arrangement extends in a radial direction and is arranged at an outer shell surface of the first wall of the first hollow structural element. The cable guide arrangement is configured to guide a submarine cable exiting the cable bushing from the cable bushing to a submarine bottom surface.

A wind turbine foundation structure comprising a hollow structural element with a circumferential wall extending in the longitudinal direction. A first cable feed-through breaking through the wall is arranged in the wall. A transition piece with an overlap region projects into the hollow structural element and a transition region projects out of the hollow structural element at the end face. A circumferential wall extends in the longitudinal direction. A second cable feed-through which breaks through the wall is arranged in the overlap region in the wall. The first and the second cable feed-through bear against one another in an at least partially overlapping manner in the assembled state of the hollow structural element and the transition piece.

Various implementations include a system for coupling a post to a foundation. The system includes a rod having a first rod end and a second rod end. The first rod end is spaced apart from a top surface of the foundation, and the second rod end is coupled to the foundation. The post has at least one side wall at least partially defining an inner cavity and an inner tube disposed within the inner cavity and coupled to the at least one side wall. The inner tube has a first tube end and a second tube end that is closer than the first tube end to a bottom end of the post. A portion of the rod is disposable within the inner tube such that the first rod end is axially spaced apart from the first tube end. The first rod end is couplable to the first tube end.

The invention relates to a fastening element for fastening a hollow composite pole to the ground at a location where a slit-formed opening is present in the ground, wherein the fastening element has a lower end portion that is configured for being positioned in the slit-formed opening, wherein a conical portion of the composite pole is abutting a conical upper portion of the fastening element.

A fence post mount device comprising: a base having at least one cavity; a first universal collet having a plurality of collet legs attached to each other through at least one of a plurality of separation notches, wherein a distal end of the first universal collet is inserted into the cavity from a proximal end of the base; a first cap nut inserted into the first universal collet; a post inserted into the cavity of the base; a full thread nut threaded into the first cap nut from a distal end of the base through an opening, wherein each of the plurality of separation notches are broken when the full thread nut is tightened into the first cap nut and each of the collet legs of the first universal collet deforms an inner wall of the post such that the post is securely locked within the cavity of the base.

The present disclosure provides a molded screw preferably comprised of a sleeve portion to receive a pole, the sleeve portion connected to a conical shank terminating at a tip. The shank is in turn further comprised of at least one thread, the thread to facilitate drilling of the screw into the ground. The thread is further comprised of recessed portions that receive earth or dirt or other substances during the drilling process and stabilize the screw when it is set in the ground. In another embodiment, the shank is further comprised of a high and low thread, which spiral in alternating fashion to the tip of the screw.

The invention relates to a clamping retainer (1) for fastening a pole, the clamping retainer (1) comprising at least two similarly shaped half shells (2) respectively having a straight side (4) and a clamping side (5) in an axial direction (A), wherein at least four or eight bores (3.1 to 3.8) running in an axial direction (A) are provided, uniformly distributed over a compass of the half shell (2), wherein a respective straight first clamping face (6) having a first width is arranged on two sides of the half shell (2) lying opposite each other in a radial direction, wherein, starting from the straight first clamping face (6), a length of the half shell (2) in the axial direction (A) increases in multiple steps (7) resulting in further straight clamping faces (8, 9, 10) with an increasing width, wherein a respective first round clamping face (11) having a shape comprising a radius or a shape of a parabola or hyperbola around its apex is arranged on two sides of the half shell (2) lying opposite each other in a radial direction and offset by 90° relative to the two sides with the straight clamping faces (6, 8, 9, 10).

According to an embodiment of the invention, there is provided an adjustable footing for a post, the adjustable footing comprising: a base, the base comprising a base plate, a fixed base nut secured to the base plate and a threaded rod secured to the base nut and extending perpendicular to the base; and a top, the top comprising a post plate having a hole and a fixed post nut secured to the post plate over the hole and dimensioned to engage the threaded rod. The post plate is secured to the post such that the threaded rod passes through the post nut and hole into a cavity in the post, and the overall height of the footing is adjustable by rotation of the base via the base nut.

A fence post mount device comprising: a base having at least one cavity; a first universal collet having a plurality of collet legs attached to each other through at least one of a plurality of separation notches, wherein a distal end of the first universal collet is inserted into the cavity from a proximal end of the base; a first cap nut inserted into the first universal collet; a post inserted into the cavity of the base; a full thread nut threaded into the first cap nut from a distal end of the base through an opening, wherein each of the plurality of separation notches are broken when the full thread nut is tightened into the first cap nut and each of the collet legs of the first universal collet deforms an inner wall of the post such that the post is securely locked within the cavity of the base.

A post support sleeve is shown and described. The post support sleeve includes a housing having a base and at least one sidewall. The housing has an interior volume and an open top end. The open top end is proportioned to fit various sized posts therein. The at least one sidewall has at least one aperture located therethrough. The at least one aperture is positioned to have a fastener placed therein. The base further has a plurality of drain apertures therethrough.
