An irrigation system comprises a central pivot; a main section pivotally connected to the central pivot; and a control system for positioning the main section to minimize wind damage. The control system comprises a location-determining component for determining a current position or bearing of the main section; a wind sensor for determining wind direction; and a computing device coupled with the wind sensor and the location-determining component for determining an optimal orientation of the main section based on an output of the wind sensor and the current position or bearing of the main section and for directing the motors to drive the wheels of the mobile towers to orient the main section in the optimal orientation.

An irrigation system includes a central pivot; a main section pivotally connected to the central pivot; and at least one solar panel supported on the main section. A control system positions the main section relative to the central pivot so that the solar panel faces the sun.
摘要:
A system and method for controlling the positioning of an extension arm of a center pivot irrigation system. The method determines at least some boundaries of a field to be irrigated; determines positions for the end tower along a path in the field; determines a desired angular orientation of the extension arm relative to the end tower for each of the positions of the end tower along the path based at least partially on the boundaries; and stores in memory desired angular orientations of the extension arm associated with positions of the end tower along the path. The method determines an actual position of the end tower while the irrigation system is in operation; determines an actual angular orientation of the extension arm relative to the end tower; accesses the memory and determines the desired angular orientation of the extension arm; and compares the actual angular orientation to the desired angular orientation.
摘要:
An apparatus is disclosed for connecting truss rods and other rigid braces of an irrigation system, wherein the rods include shaft sections with enlarged cylindrical heads at the ends thereof and form part of a truss-type framework supporting a conduit. A coupling assembly for holding a pair of such truss rods together in axial alignment is disclosed and includes a top plate and a bottom plate clamped together with a connecting bolt having a non-circular collar. The collar on the bolt cooperates with similarly shaped holes in the plates of the coupling assembly to prevent relative rotation between the plates and also between the bolt and the coupling assembly. The bolt includes a head with a hexagonal drive recess for use with an appropriate driving tool.
摘要:
A control system for stopping or reversing movement of an irrigation system comprises an electronic proximity sensor and a control device. The electronic proximity sensor is configured for mounting to the irrigation system and operable to detect a target. The control device is responsive to the electronic proximity sensor for stopping or reversing movement of the irrigation system when the electronic proximity sensor detects the target.
摘要:
A hose-fed lateral move irrigation system and method that utilizes a pipe with a plurality of sprinklers attached to a wheeled cart that pulls a flexible-hose assembly therebehind using at least one onboard winch and travels laterally with the pipe and sprinklers relative to a field so that a sufficient amount of hose may be used to enable total automation of the system.
摘要:
A truss-type support system for a water-carrying conduit of an irrigation system includes a plurality of elongated truss braces and at least one truss rod for interconnecting the truss braces. The truss braces each have a pair of interconnected legs separated by an angle of approximately 40°-70°.
摘要:
An apparatus and method of moving a mobile tower using solar power are disclosed for use with an irrigation system. The disclosed improvement includes a solar panel with a collecting surface to convert light energy to electrical energy, an electrical charge source in communication with the solar panel to receive electrical energy, and a motor to drive a ground-engaging wheel in communication with the electrical charge source. The improvement also includes a direction control system for regulating rotation of the solar panel and a tilt assembly for adjusting the angle of the solar panel to maintain the disposition of the collecting surface in alignment with the direction of incoming sunlight. The method of moving the mobile tower includes collecting light energy with a solar panel, converting the light energy into electrical energy, and driving a wheel of the mobile tower with a motor powered by the converted electrical energy.
