A cable fixing device includes an upper body to contact a cable, a lower body to travel through an opening of a plate-shaped structure along an engagement direction, and a middle body positioned between the upper body and the lower body along the engagement direction, the middle body to contact a side wall of the opening of the plate-shaped structure, where a height H1 of the sidewall of the opening of the plate-shape structure along the engagement position is smaller than a height H2 of the middle body along the engagement direction, and where a height difference ΔH between H2 and H1 decreases as the cable travels through the upper body along the engagement direction.

In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure, a torque tube suspending on the pivot device and aligned within an opening of the support, and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

A clamp equipped nozzle for enabling spooling of a hose includes a body defining a lumen having a central axis and configured to enable fluid to flow therethrough. A fluid outlet is in fluid communication with the body and is disposed at a first end of the body. The fluid outlet is configured to enable fluid to flow out of the clamp equipped nozzle defining a flow pattern. A coupler is configured to couple the body to an end of the hose and is disposed at a second end of the body. A clamp is configured to retain a section of the hose and is disposed along a longitudinal portion of the body. The clamp includes walls in a cylindrical configuration, the walls defining a longitudinal length that is approximately parallel the body.
