A temporary maintenance enclosure for the maintenance of at least part of a turbine blade, the enclosure comprises a platform arranged, in use, to border at least part of the circumference of a blade in need of maintenance; at least one wall and a roof which are carried by the platform; the at least one wall extending from the platform; wherein said roof extends from the wall towards the blade; and wherein the enclosure further comprises a flexible sheath which seals onto the blade to provide a sealed volume for maintenance of said blade.

A folding tent with central self-lock structure comprises a plurality of tent leg tubes, a plurality of side cross units, a plurality of middle cross units and at least one central self-lock mechanism. The central self-lock mechanism is configured to be installed in cooperation with one end of the middle cross units. The central self-lock mechanism includes a lock rod assembly, a self-lock unit, an upper disc member and a lower disc assembly. When the folding tent is in an unfolded state, the self-lock unit and the lock rod assembly are locked, and a spacing between the upper disc member and the lower disc assembly is the smallest; when the folding tent is in a retracted state, the self-lock unit and the lock rod assembly are unlocked, the lock rod assembly is telescopic, and the spacing between the upper disc member and the lower disc assembly increases with the retraction.

Tents are disclosed herein. A tent includes a plurality of support frames, each support frame being bent in a shape of an arch and having two ends configured to be fixed on a ground surface when the tent is assembled. Each support frame crosses over at least one other support frame when the tent is assembled. Each support frame is positioned such that the ends of the support frame are positioned on non-adjacent vertices of a polygonal base surface when the tent is assembled.

A half-pyramid backpacking type fabric shelter with sufficient stability to omit a front guyline and remain standing when the front entrance is open, and with improved head-room and useable floor space. The peak of the shelter canopy at the front entrance is supported by a vertical pole, and includes short forward and rear canopy ridgelines whose ends are located below the peak to receive the tips of a horizontal cross-strut crossing the vertical pole below the peak. The rear corners of the shelter canopy are preferably raised and structured by a triangular strut structure.

The present invention relates to an expandable shelter, the shelter includes an upright support and ribs for supporting a canopy. Stretchers are provided for stretching the ribs from the upright support. A runner is provided for moving downwards along the upright support so that the stretchers stretch the ribs from the upright support to expand the shelter. Advantageously, a shelter assembly whereby the runner moves downward to stretch the ribs may provide a compact collapsed shelter with more expansive sheltering when compared with other shelters where the runner instead moves upwards for expansion.

A rainwater harvesting apparatus and system for an emergency shelter includes a platform defining an aperture. A threaded fastener is inserted through the aperture and is rotatable through the aperture. A planar panel assembly is fastened to the platform by the threaded fastener. The planar panel assembly is configured to move on the threaded fastener along a longitudinal axis of the threaded fastener as the threaded fastener is rotated through the aperture in the platform. A canopy is secured to the planar panel assembly, such that a segment of the canopy moves together with the planar panel assembly along the longitudinal axis of the threaded fastener as the planar panel assembly moves on the threaded fastener.

A hydroponic tent is provided which comprises a tent fabric cover having an inner surface which is at least in part light-reflective, and a tent frame to support the tent fabric cover in an assembled condition. The tent frame comprises a plurality of support legs, a plurality of support linkages positioned at or adjacent to an in use upper end of the support legs, the plurality of support linkages being interconnected so as to allow the tent frame to collapse in concertina. There is further provided a hanging frame assembly having first and second support bars and at least one bridging bar, the first support bar being engagable with the tent frame at or adjacent to one of the plurality of support linkages, the second support bar being engagable with the tent frame at or adjacent to another one of the plurality of support linkages, and the at least one bridging bar being supportable between the first and second support bars.
