Embodiment Construction

[0030] figure 1A view of the shaft housing SG of the quadrilateral sprinkler arrangement according to the invention is shown obliquely from above. The shaft housing SG is designed to be buried in the ground and has a water connection WA at the lower end. The shaft housing SG delimits an inner space with, for example, an essentially cylindrical outer wall AW, which is closed upwards by a removable cover DE. The cover DE is rotatable about a vertical axis as indicated by the arrow DR. By means of the locking device AM, which can be manually operated between the roof and the shaft housing SG, the roof can be fixed in different, preferably arbitrary, rotational positions about a vertical axis of rotation. Advantageously, the locking device can simultaneously be used to prevent the top cover from being lifted by the shaft casing. In the upwardly pointing roof surface DF of the roof there is a recess AU which, in the shown rest position of the quadrilateral sprinkler arrangement,...

Abstract

For quadrilateral sprinkler arrangements with quadrilateral sprinklers arranged in a shaft buried in the ground, it is proposed that the sprinkler head (RK) passes through the top cover (DE) located upwardly closing the shaft casing (SG) The grooves (AU) in the roof surface (DF) of the roof are moved from the sunken position into the operating position above the roof surface and back. In this case, the recess in the roof surface is closed by the sprinkler head itself in the lowered rest position of the quadrilateral sprinkler, which then forms the quadrilateral sprinkler arrangement together with the outer surface with the nozzle arrangement (DA) part of the top surface.

Description

technical field [0001] The present invention relates to a quadrilateral sprinkler assembly having a quadrilateral sprinkler and a wellbore casing. Background technique [0002] For spraying lawn surfaces, especially circular and fan sprinklers as well as quadrilateral sprinklers are used, which usually comprise a sprinkler head driven by a water-driven sprinkler drive, which sprinkler head has a nozzle arrangement. Two types of sprinklers are known: upright sprinklers, which are supplied with a water flow via a hose and can be installed on the ground in a variable position; in the wellbore casing. In the rest position, the pendant sprinkler arrangement has a top surface which is almost at the same level as the surrounding ground, which can be stepped on and over which conventional lawn mowers can be driven. [0003] In round and fan sprinklers of the downsprinkler type, the sprinkler head is guided vertically displaceably in the sprinkler housing, wherein the water jets su...
