Submitted is a modular stationary portable photovoltaic solar powered electrical generation, storage and supply device and light tower. The device consists of an elongated cube or rectangular prism shaped support structure with a flat base, flat sides and a flat decked top to form a protective crate shaped module when the various components, such as the solar panel arrays, telescoping mast, and light assembly or outriggers of the device are retracted to where the boundaries may be defined by the perimeters of the cube or prism. This modular design can allow for the modules to be stored, loaded, or shipped quickly, efficiently, and in greater quantities on flatbeds, in shipping containers, in warehouses, and other settings and modes where they can not only be packed end to end and side to side with no unused space, but can also be stacked up to three modules high for significantly higher storage density. The interconnectivity of multiple modules to create incrementally larger power generation, storage and distribution systems provides an easily adaptable solution to larger temporary power demands.

Modular photovoltaic light and power cube

A strainer system having two separate strainers positioned in parallel, where one strainer can be cleaned while still permitting normal flow through the other strainer. The system flow circuit is arranged so that a high pressure backwashing flow can be applied to one strainer while the other strainer is providing its normal straining function. The backwashed strainer is then isolated by valves so that its access flange can be removed and the particulate buildup within the valve plug cleaned out. The strainer is then returned to service following the replacement of the access flange. In this manner, it is possible to alternate between the two strainers so that continuous flow can be maintained to the hydraulic choke located downstream of the strainer system.

Flow system for a hydraulic choke solids strainer

The invention contemplates a strainer based upon a four-way, two-position rotary cylindrical plug valve having a hollow plug. The normal entry port for the sealing plug of the plug valve is a circular radial hole passing from the exterior of the plug into the interior cavity of the plug. The normal exit port for the sealing plug is a regular array of small holes across from and coaxial with the normal entry hole. The ports for the valve body are in two pairs positioned at 90&#xb0; from each other, with the axes of the ports lying in the same transverse plane as the ports of the valve plug.

Solids strainer system for a hydraulic choke

An embodiment of the invention involves a method for servicing a choke valve that includes disconnecting a choke actuator and at least one internal valve component engaged therewith from the choke valve body of the choke valve and moving the same in a generally linear path away from the choke valve body along the axis of the choke valve body.

Apparatus and methods for servicing a hydraulic choke

The present invention relates to an apparatus for use in field servicing a choke valve system. The apparatus is used for lifting, manipulating, and handling the heavy components of hydraulic choke valves. The apparatus includes an elongated track, a choke valve support structure, a trolley that selectably reciprocates along a length of the trolley, and an attachment mechanism for attaching a choke actuator to the trolley.

Manipulator system for servicing a hydraulic choke

The present invention relates to a mechanism for preventing damage to the actuator of a hydraulic choke valve in the event of excessive backpressure on the outlet of the choke. The backpressure relief device is applicable to a choke valve which meters flow from a high pressure annular region around the axially reciprocable choke throttling member into a low pressure exit channel coaxial with the throttling member. In particular, a shearable means is used to connect the reciprocable control shank of the actuator to the throttling valve member of the choke valve. In the event of excessive pressure on the exit channel of the choke valve, the shearable means will shear, thereby fully opening the valve and permitting the excessive pressure to escape. The shearable means is readily replaced so that the valve easily can be put back into operating condition.
