Device for routing cables, more particularly intended for routing and distributing electric cables having an elongated shape (1) with a U-shaped cross-section consisting of an assembly of two side posts (3) forming the arms of the U and of a base (2) forming the bottom of the U. The side posts (3) and the base (2) are substantially made from a composite material and/or a strengthened plastic material and in that at least one side post (3) is pivotally mounted while being jointed to the base (2) about an axis of rotation (30) by at least one hinge (4) and in that it comprises snap-coupling means (35,26,63,7) and abutment means (22,23,38,29,27) capable of locking the side post perpendicularly to said base (2) under the action of its rotation.

The invention discloses a novel high-sensitivity controllable sprinkler irrigation system. The novel high-sensitivity controllable sprinkler irrigation system comprises a water tower and a plurality of sprinkler irrigation pipes, wherein the sprinkler irrigation pipes are vertically arranged; the multiple sprinkler irrigation pipes are arranged in a communicated mode through connecting pipes whichare transversely arranged; the water tower is of a hollow structure; a water pump is arranged on the side wall of the lower side of the water tower; a water inlet pipe of the water pump is located atthe bottom of the water tower; a water outlet pipe of the water pump penetrates through the side wall of the water tower and is communicated with the side wall of one of the sprinkler irrigation pipes; sprinkler irrigation spray heads are arranged on the side walls of the upper sides of the sprinkler irrigation pipes; partition plates which are transversely arranged are arranged in the inner walls of the sprinkler irrigation spray heads; the side walls of the very centers of the partition plates are provided with strip-shaped water outlets which are transversely arranged; the side walls of the lower sides of the partition plates are provided with arc-shaped sliding grooves; and the arc-shaped sliding grooves are communicated with the strip-shaped water outlets. According to the novel high-sensitivity controllable sprinkler irrigation system, the flow of sprinkler irrigation can be strictly controlled, the flow adjusting precision is high, and the adjusting operation is time-saving andlabor-saving.
