Disclosed is an intelligent water supply planting pot, including a pot body, a water delivery pipe, and a controller. The pot body is recessed to form a containing cavity. A partition plate for dividing the containing cavity into a planting cavity and an equipment cavity is arranged in the containing cavity. The water delivery pipe penetrates through the partition plate and is contained in the containing cavity. A humidity detector is arranged in the planting cavity. An electromagnetic valve is arranged in the water delivery pipe. The controller is arranged in the equipment cavity and is electrically connected to the humidity detector and the electromagnetic valve. A solar panel with an adjustable height is also arranged on the pot body. The solar panel is electrically connected to the controller.

A supporting and fixing structure and a photovoltaic tracking and mounting system. The supporting and fixing structure includes a main support rod, a mounting rod, a rotary power device and a plurality of auxiliary support rods. The mounting rod is rotatably mounted on the main support rod through the rotary power device. The auxiliary support rods are rotatably matched with the mounting rod. The auxiliary support rod is configured to support the mounting rod. It further includes a valve stem, a housing, an inner housing plate and a plunger rod. The inner housing plate is disposed in the housing, and separates a space in the housing to be two chambers. The plunger rod is movably installed on a housing wall of the housing, and is configured for blocking or communicating the first housing chamber. The valve stem is in sliding and sealing fit with the second housing chamber.

In an example, a system to facilitate installation of a drive linkage in a solar array at or below an installation surface includes a housing and first and second interconnection assemblies. The housing is installed on or below the installation surface and is configured to at least partially enclose and protect the drive linkage at or below the installation surface. The first interconnection assembly extends between a first drive assembly of a first solar tracker supported above the installation surface by a support structure and a first end of the drive linkage at or below the installation surface. The second interconnection assembly extends between a second drive assembly of a second solar tracker supported above the installation surface by the support structure and a second end of the drive linkage at or below the installation surface.
