A water spraying fan for firefighting. The water spraying fan includes a fan mechanism mounted onto a rotatable surface attached to a base. The fan mechanism has a plurality of fan blades connected to a power source and adapted to rotate quickly, creating a strong air flow when powered on. A cage encloses the fan blades and includes one or more circular manifolds secured to a front side and positioned concentric to the fan blade axis. The manifolds contain a plurality of nozzles that are configured to disperse a liquid, such as water. The manifolds are connected to a water source via a flow control box. When activated, water flows out of the nozzles and is carried across an extended distance via the water pressure and the strong air flow created by the fan mechanism. The water spraying fan can be rotated or tilted to achieve optimal positioning.

A product applicator system for distributing a liquid product accurately using low volume applications which minimize the quantity of product used and ensures more accurate results. The product applicator system generally includes a housing which includes a removable inlet port mount and outlet port mount. The positioning of the inlet and outlet port mounts on the housing is interchangeable. Supply hoses provide a product to the inlet port mount where the product is traversed through internal conduits to exit the housing via oscillating and overlapping spray heads. An internal motor provides oscillating motion to the spray heads. A rotator assembly which includes a rotator motor may be utilized to orient the housing in horizontal, vertical, or various diagonal orientations. The housing is adapted to either connect to a vehicle, be positioned on a stationary or movable platform, or be connected to a boom using boom connectors.

A nozzle adjustment member for a sprinkler is revealed. A plurality of nozzle tubes aligned in at least one row is positioned on a wall of a hollow pipe. A top end of the nozzle tube is projecting to an outside of the hollow pipe. At least one pivot support is disposed on the outside of the hollow pipe. Each pivot support is pivoted with an adjustment piece having a plurality of guiding openings. The guiding openings are positioned over the plurality of nozzle tubes correspondingly. A nozzle cover is connected with the outside of the hollow pipe for covering the adjustment piece. A plurality of long through holes for mounting the corresponding nozzle tubes is arranged at the nozzle cover. Around a pivot hole, the adjustment piece swings so as to drive the plurality of nozzle tubes moving at an angle and different water distribution patterns are provided.

A Large Area Liquid Solution Application includes a boom equipped with a series of easily removable spray nozzles, for easier cleaning and maintenance, attached to a standard truck trailer hitch receiver with a pump assembly attached onto a reservoir loaded onto a truck bed. This invention presents an effective deicing apparatus and method to spray brine evenly on the pavement. The reservoir is easily secured manually with standard ratchet straps and the boom connects to any standard truck tow hitch without the use of tools. The equipment panel with attached pump is easily removable and the pump fittings and corresponding output hoses manually snap in and out of place to allow easier maintenance and cleaning. Communicating wirelessly, the present invention is activated by a wireless key enabling a truck driver to control the system without needing to exit the vehicle and manually shut of the sprayer.

A spraying system for spraying a fluid includes a nozzle assembly configured to spray the fluid in response to receiving a control signal, a sensor configured to transmit a detection signal upon detection of a target, and a user interface configured to receive input from an operator. The spraying system further includes a control system communicatively coupled to the sensor to receive the detection signal from the sensor, the control system configured to transmit the control signal to the nozzle assembly at least in part in response to reception of the detection signal, the control system further configured to determine a fluid band length and an offset distance of the fluid band length from the target based at least in part on information input by the operator to the user interface. The user interface displays a graphic representation of the fluid band length and the offset distance relative to the target.

A shower arm attachment assembly including an arm coupling member, a shower pipe coupling member, and a locking member. The arm coupling member may fluidly connect to a shower arm for a showerhead and the shower pipe coupling member may fluidly connect to a shower pipe. The arm coupling member connects to the shower pipe coupling member and is selectively rotatably relative thereto. The locking member selectively controls rotation of the arm coupling member relative to the shower pipe coupling member.

A combination nozzle and a device for applying a viscous material, particularly an adhesive, to a component edge includes two wide-slot nozzles lying close to one another. The first nozzle applies the viscous material and the second nozzle supplies a gas such as air for shaping the applied material bead. A nozzle mount has a guide roller placed on and movable about the edge of the component during application. A connector element via a connecting mechanism allows movement of the nozzle mount parallel to the surface normal on the component edge to press the guide roller against the edge during the application process by a spring mechanism. With the proposed combination nozzle and the proposed device, an optimal wetting of the component edge with the viscous material can be achieved, and additionally the component tolerances are compensated without the necessity of an elaborate sensor system.

A cleaning apparatus for a ceiling transport vehicle is provided which can be advantageously installed in a clean room. A cleaning apparatus for cleaning a ceiling transport vehicle includes an air blower for blowing air to the ceiling transport vehicle when the ceiling transport vehicle, which can travel along a travel rail provided on a ceiling side in a clean room, is stationary in a closed off space which is closed off from exterior space.

Disclosed is a pipe-shape structure coating device. A pipe-shape structure coating device according to one embodiment of the present invention includes: a rack unit on which a pipe-shape structure is placed, and a work vehicle which carries out a coating process on an inner surface of the pipe-shape structure by driving inside the pipe-shape structure placed on the rack unit along a longitudinal direction of the pipe-shape structure.

A sprinkling device includes a grip, a rotary seat sealingly mounted onto the grip and a sprinkling head sealingly and rotatably mounted onto the rotary seat. The sprinkling device is used as a spray gun when an axis of sprinkling head co-axially corresponds to that of the rotary seat or the axis of sprinkling head is parallel to that of the rotary seat. The sprinkling device is used as a sprinkler when the axes of the sprinkling head and the rotary seat form an angle, wherein the grip is used as a platform and the sprinkling head upwardly sprays water.
