AI Technical Summary
When existing sprinkler systems increase spray density and expand pipeline networks to improve coverage efficiency, the complexity of the equipment and the energy consumption of operation rise simultaneously, resulting in increased material loss rate and larger coverage blind spots.
Multiple spray components are used, including a mounting base, a nozzle, a first swing arm, an actuator, a second swing arm, and a pull cable. The actuator pulls the pull cable, causing the mounting base to swing the nozzle, thus covering a larger area, simplifying the piping network, and reducing the spray density.
With the same spray area, reducing spray density simplifies the pipeline network, reduces equipment complexity, and lowers energy consumption.

Abstract
Description
Technical Field
[0001] This application relates to the field of spray technology, and more particularly to a spray device. Background Technology
[0002] In the field of industrial environmental governance, traditional spraying devices generally adopt a multi-nozzle array layout to achieve coverage of the work area. This is mainly manifested in the dual environmental regulation of the target area by atomizing the water medium under pressure through the pipeline transportation system: on the one hand, the phase change of water molecules is used to absorb the heat energy of the work surface to achieve gradient cooling; on the other hand, air purification is achieved by means of inertial collision and interception and capture of droplets and suspended particles.
[0003] Currently, increasing spray density and expanding pipeline networks are commonly used to improve coverage efficiency. However, there is a technical contradiction that equipment complexity and operating energy consumption increase simultaneously. Specifically, this manifests as increased material loss due to pipeline redundancy and an increased proportion of coverage blind spots caused by improper control of atomization unit spacing. Utility Model Content

[0006] In one possible implementation, the actuator is a double-rod double-outlet sliding cylinder.

When the spraying device operates, the nozzles in the multiple spraying components spray atomized water towards the spraying target.

[0020] The spraying device provided in this application embodiment includes multiple spraying components 10, which are disposed to the side and above the spraying target, such as... Figure 1 As shown. For example, Figure 1 The spraying device shown includes four spraying components 10 located above the spraying target, one spraying component 10 located to the left of the spraying target, and one spraying component 10 located to the right of the spraying target.
[0021] Reference Figure 2 Each spray assembly 10 includes a mounting base 100, a nozzle 200, a first swing arm 300, an actuator 400, a second swing arm 500, and two pull cables 600.
[0022] The nozzle 200 is connected to the mounting base 100 and is used to spray atomized water vapor onto the spray target to achieve cooling or dust removal.
[0023] One end of the first swing arm 300 is fixedly connected to the mounting base 100. Specifically, the first swing arm 300 and the mounting base 100 can be connected by bolts, welding, riveting, or other methods.
[0024] The actuator 400 is fixedly installed and has two actuating ends 410. The two actuating ends 410 are linked together, and when one actuating end 410 extends outward, the other actuating end 410 retracts inward.
[0025] One end of the second swing arm 500 is fixedly connected to the actuator 400, and the other end of the second swing arm 500 is hinged to the end of the first swing arm 300 away from the mounting base 100. Specifically, the second swing arm 500 and the actuator 400 can be connected by bolts, welding, riveting, or other methods.
[0026] One end of each of the two pull wires 600 is connected to one of the two actuating ends 410, and the other end of each of the two pull wires 600 is connected to the mounting base 100. The two actuating ends 410 are located on both sides of the rotation axis of the first swing arm 300. When one actuating end 410 pulls the pull wire 600, the other actuating end 410 releases the pull wire 600.
[0027] When the spraying device operates, the spray heads in multiple spray components 10 spray atomized water towards the target area. The two actuating ends 410 of the actuator 400 pull the mounting base 100 through two pull cables 600, causing the first swing arm 300 to rotate relative to the second swing arm 500, which in turn causes the mounting base 100 to drive the spray head 200 to swing. Each spray component 10 of this spraying device covers a larger area through the swing of the spray head 200. With the same spray area, this spraying device reduces the spray density, simplifies the pipeline network, reduces the overall complexity of the equipment, and lowers the spraying energy consumption.
[0028] Continue to refer to Figure 2 In some embodiments of this application, the actuator 400 is a double-rod double-outlet sliding cylinder.
[0029] In some other embodiments of this application, the actuator 400 may be a bidirectional hydraulic cylinder.
[0030] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the spray assembly 10 further includes two cable fixing assemblies 700, which are used to fix two cables 600 respectively. Specifically, the cable fixing assembly 700 includes a fixing plate 710, a first eye bolt 720, and a second eye bolt 730. The fixing plate 710 is connected to the actuating end 410 of the actuator 400; specifically, the fixing plate 710 and the actuating end 410 of the actuator 400 can be connected by bolts, riveting, welding, etc. The first eye bolt 720 is threaded to the fixing plate 710, and the second eye bolt 730 is threaded to the mounting base 100. The two ends of the cable 600 are respectively connected to the first eye bolt 720 and the second eye bolt 730.
[0031] When the actuator 400 causes the mounting base 100 to swing, one of the actuator ends 410 of the actuator 400 extends outward and pulls the pull cable 600 through the fixing plate 710 and the first lifting eye bolt 720. The pull cable 600 pulls the mounting base 100 through the second lifting eye bolt 730. The other actuator end 410 of the actuator 400 retracts inward and releases the pull cable 600 through the fixing plate 710 and the first lifting eye bolt 720. This causes the mounting base 100 to swing.
[0032] Furthermore, referring to Figure 3 The fixing plate 710 includes a first connecting portion 711 and a second connecting portion 712. The first connecting portion 711 is connected to the actuating end 410; the second connecting portion 712 is integrally connected to the first connecting portion 711, and the second connecting portion 712 is triangular and points towards the mounting base 100. The first eye bolt 720 is threadedly connected to the second connecting portion 712. The second connecting portion 712 allows the second eye bolt 730 to be closer to the mounting base 100, thereby avoiding interference between the pull wire 600 and the actuator 400 when the actuating end 410 is actuated.
[0033] like Figure 2 As shown, the mounting base 100 has two slots 110, which are used to avoid the two pull wires 600 when the mounting base 100 swings. Specifically, with Figure 2 Taking the orientation shown as an example, when the first swing arm 300 rotates clockwise and causes the mounting base 100 to swing, the pull wire 600 on the left enters the slot 110 on the left; when the first swing arm 300 rotates counterclockwise and causes the mounting base 100 to swing, the pull wire 600 on the right enters the slot 110 on the right.
[0034] like Figure 2 As shown, in some embodiments of this application, multiple nozzles 200 are arranged in series along a direction parallel to the rotation axis of the first swing arm 300. Specifically, multiple nozzles 200 are spaced apart along a direction parallel to the rotation axis of the first swing arm 300, and adjacent nozzles 200 are connected by pipelines.
[0035] For example, Figure 2 The diagram shows three nozzles 200 spaced apart along a direction parallel to the rotation axis of the first swing arm 300. The nozzle 200 on the left and the nozzle 200 in the middle are mounted on a three-way valve. One end of the three-way valve of the left nozzle 200 is connected to the water pump through a pipeline, and the other end of the three-way valve of the left nozzle 200 is connected to one end of the three-way valve of the middle nozzle 200 through a pipeline. The other end of the three-way valve of the middle nozzle 200 is connected to the right nozzle 200 through a pipeline. The pipelines are fixedly connected to the mounting base 100 by pipe clamps.
[0036] In some other embodiments of this application, only one nozzle 200 may be installed on the mounting base 100, and the nozzle 200 is connected to the water pump through a pipeline.
