One embodiment of the present invention provides a water circulation-type malodor reduction system including a fluid supply line that supplies a fluid to a roof of a livestock barn, a first reservoir which is provided on one side of the roof and in which the fluid flowing along the roof is accommodated, and an accommodation part in which the fluid falling from the first reservoir is accommodated, wherein the accommodation part is disposed so that the fluid falls in an S shape.

A roof drain including a flange defining an opening having a central axis, and a throat extending axially from the flange to define a channel having an inner surface therethrough. Where the throat includes a first end generally corresponding with the flange, and a second end opposite the first end, and where the second end is configured to be coupled to a drain outlet. The inner surface of the channel includes a cross-sectional shape taken normal to the central axis, and where the cross-sectional shape continuously and smoothly decreases or remains the same from the first end to the second end.

A drain cover assembly. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or portion with a large area and extending outwardly in an arcuate configuration and having openings for fluid flow. The lower portion may be oriented at a small angle with respect to the horizontal. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and also extend arcuately and having openings. Locking assemblies may be adjustable to secure the cover to a clamping collar over a drain. The locking assembly may include a base that slidingly engages the collar, and a housing that is secured over the base and to secure the cover to the collar.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

A kit for installing a rain chain to a rain gutter includes a gutter attachment unit having an outlet tube extendable through a drain aperture of the rain gutter. A rain chain support is attachable to the outlet tube and includes a sloped member which aligns and self-centers a rain chain coupled thereto with the outlet tube such that rainwater exiting the outlet tube is directed onto the rain chain.

Drainage device for a construction, in particular a roof of a building or a terrace, for discharging rainwater, comprising: a drainage head (11) supported on the construction around a flow channel of the latter and defining a recovery space communicating with the outside and with the flow channel; and a mounting means comprising a support or attachment means (23) capable of being engaged inside the discharge channel and abutting against the peripheral wall of the discharge channel and a biasing means (24) which connects the drainage head and the support or attachment means and is capable of acting on the support or attachment means so as to keep the drainage head supported on the outer surface of the construction.
