Description

Technical Field

[0001] This invention relates to the field of dust suppression device technology, specifically a three-dimensional dust suppression spray system. Background Technology

[0002] Currently, in the process of urban construction and development, the demolition and construction of buildings are often accompanied by a large amount of dust emissions. This dust not only seriously pollutes the environment but also harms human health. Therefore, how to effectively control and reduce dust at construction sites has become an important research topic. Existing dust reduction measures mainly include wet operation, covering and shielding, negative pressure dust removal and other means. Although these measures have alleviated the dust problem to some extent, they still have many shortcomings, especially in terms of efficiency and flexibility.

[0003] Currently, common dust suppression methods mainly involve spraying water mist into the air or onto the ground using water trucks or fixed sprinkler systems to absorb dust particles in the air. This method is simple, easy to implement, and low in cost, but it is difficult to achieve full coverage in complex terrain and variable environments, and it consumes a lot of water resources. Alternatively, covering and shielding can be used, such as using dust nets or other shielding materials to enclose the construction area to prevent dust from spreading. This approach can effectively reduce dust, but it requires a lot of manpower and time to set up and maintain, and is not suitable for large-scale or long-term projects. Another method is to use negative pressure dust collection, which creates a local negative pressure zone by setting up dust collectors and fans to suck dust into the filtration equipment. This method is very effective, but for large open areas, the equipment investment and operating costs are high, and installation is inconvenient.

[0004] While the aforementioned dust suppression methods can reduce dust pollution to some extent, they also have obvious limitations. For example, wet operations are limited by water source conditions and have limited coverage; covering and shielding require a lot of manual intervention and affect the construction progress; negative pressure dust removal equipment is expensive and complicated to install, making it unsuitable for temporary and small-scale projects. Therefore, there is an urgent need for a three-dimensional dust suppression spray system. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional dust suppression spray system to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a three-dimensional dust suppression spray system, including a pole mechanism, wherein the pole mechanism includes a mounting plate, a pole is fixedly connected to the top of the mounting plate, and a lifting unit is provided on the surface of the pole; The lifting unit is used to adjust the height of the spray device. The lifting unit includes a mounting frame 1. A first motor is fixedly connected to the surface of the mounting frame 1. A winding roller is fixedly connected to the output end of the first motor through the mounting frame 1. A pull line is fixedly connected to the surface of the winding roller. A guide roller 1 is slidably connected to the surface of the pull line. A guide frame is rotatably connected to the side of the guide roller 1. A guide roller 2 is also slidably connected to the surface of the pull line. A guide frame 1 is rotatably connected to the side of the guide roller 2. A limit block is fixedly connected to the inner wall of the guide frame 1. A guide roller 3 is also slidably connected to the surface of the pull line. A guide frame 2 is rotatably connected to the side of the guide roller 3. A lifting ring is fixedly connected to the end of the pull line away from the winding roller.

[0007] A support plate is fixedly connected to the surface of the upright, an extension rod is slidably connected to the inner wall of the upright, a connecting plate is fixedly connected to the top of the extension rod, and an electric telescopic rod is fixedly connected to the surface of the support plate.

[0008] A limit frame is fixedly connected to the surface of the upright, and the telescopic end of the electric telescopic pole is fixedly connected to the connecting plate.

[0009] The pole support mechanism also includes a steering unit, which helps the sprinkler system to turn, thereby expanding the sprinkler range. The steering unit includes a first rotating frame, a second motor is fixedly connected to the bottom end of the first rotating frame, and a second rotating frame is fixedly connected to the output end of the second motor through the first rotating frame. A rotating rod is rotatably connected to the inner wall of the second rotating frame, and a groove is formed on the surface of the rotating rod. A water supply hose is fixedly connected to the inner wall of the groove, and a second mounting frame is fixedly connected to the surface of the rotating rod. A high-pressure nozzle is fixedly connected to the surface of the second mounting frame.

[0010] The water delivery hose is fixedly connected to the high-pressure nozzle through the rotating rod, and the inner wall of the first rotating frame is rotatably connected to the second rotating frame.

[0011] The surface of the rotating frame is fixedly connected to the extension rod, and the surface of the water delivery hose is slidably connected to the inner wall of the limiting frame.

[0012] The bottom end of the lifting ring is fixedly connected to the rotating rod. Two guide frames are provided, and the two guide frames are fixedly connected to the inner walls of the support plate and the connecting plate, respectively.

[0013] The bottom end of the first conductor frame is fixedly connected to the top end of the extension rod, and the bottom end of the second conductor frame is fixedly connected to the rotating rod.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention achieves high-precision, overload-resistant adjustment of the pitch angle of the rotating rod through the longitudinal traction and 180° limit design of the winding mechanism. Traditional sprinkler systems often use gear transmission or free hinge structures for angle adjustment, which suffers from problems such as angle loss of control and complex maintenance. For example, gear sets or hinges are prone to excessive nozzle sway due to inertia or wind load, requiring additional mechanical stops. Furthermore, gear meshing wear requires regular lubrication, and hinge structures are prone to rust and jamming. In contrast, this invention innovatively adopts a one-way traction mechanism of winding roller-pull wire, which tightens or releases the wire longitudinally. The direct drive rotating rod can pitch within a limited angle of 0° to 180° in the vertical plane, from 90° downwards to 90° upwards. Utilizing the rigid constraint of the guide roller and the limiting block, the nozzle angle adjustment can be precisely locked at the target angle without additional limiting devices. This avoids the swaying and deviation caused by inertia or external forces in traditional structures. For example, in construction site applications, the nozzle can stably maintain a downward spray angle of 60° without deviation in strong winds, improving angle control stability. Furthermore, the cable pulling mechanism requires no lubrication or maintenance, significantly reducing operation and maintenance costs.

[0015] Secondly, this invention solves the industry problems of easy wear of rotating parts and pipeline leakage through mechanical coupling and dynamic sealing design. In the prior art, the rotary joint of the sprinkler system often fails to seal due to frequent rotation, and the water supply pipeline is prone to bending and breaking when it expands and contracts. This invention innovatively adopts a groove-embedded water supply hose and a spiral armored protection structure, so that the hose only bends locally when the rotating rod rotates and rises and falls, reducing fatigue damage and extending the service life to more than twice that of the traditional design. At the same time, through the rigid connection between the lifting ring and the rotating rod, the lifting force is directly transmitted to the nozzle support structure, avoiding the chain wear problem of the traditional pulley assembly and reducing the failure rate.

[0016] Third, this invention adopts an integrated pre-assembled structure, which facilitates rapid installation and deployment. The entire machine can be erected simply by fixing the mounting plate to the ground. Traditional dust suppression equipment often requires on-site assembly of the poles, connection of pipelines, and debugging of the lifting mechanism, which takes up to 2-3 hours and relies on professional personnel. This invention, through modular pre-assembled design, integrates the poles, lifting unit, and steering unit onto the mounting plate before leaving the factory. Users only need to anchor the mounting plate directly to the ground with expansion bolts to complete the installation. No additional assembly is required throughout the process, and the deployment time is shortened to less than 30 minutes. For example, in temporary dust suppression scenarios at construction sites, workers only need to locate, drill holes, insert expansion bolts, and lock the mounting plate before the system can be powered on and operated. Compared with traditional equipment, the installation efficiency is improved, and no professional technicians are required to provide on-site support. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: a three-dimensional dust suppression spray system, including a pole mechanism 1, the pole mechanism 1 including a mounting plate 10, the top of the mounting plate 10 being fixedly connected to a pole 1001, and a lifting unit 2 being provided on the surface of the pole 1001; The lifting unit 2 is used to adjust the height of the spray device. The lifting unit 2 includes a mounting frame 20. A first motor 2001 is fixedly connected to the surface of the mounting frame 20. A winding roller 2002 is fixedly connected to the output end of the first motor 2001 through the mounting frame 20. A pull line 2003 is fixedly connected to the surface of the winding roller 2002. A guide roller 2005 is slidably connected to the surface of the pull line 2003. A guide frame 2004 is rotatably connected to the side of the guide roller 2005. A guide roller 2007 is also slidably connected to the surface of the pull line 2003. A guide frame 1006 is rotatably connected to the side of the guide roller 2007. A limit block 2008 is fixedly connected to the inner wall of the guide frame 1006. A guide roller 3010 is also slidably connected to the surface of the pull line 2003. A guide frame 2009 is rotatably connected to the side of the guide roller 3010. A lifting ring 2011 is fixedly connected to the end of the pull line 2003 away from the winding roller 2002.

[0021] The core function of lifting unit 2 is to drive the winding roller 2002 to wind and unwind the pull line 2003 via the first motor 2001. Combined with the three-stage guiding layout of guide roller 1 2005, guide roller 2 2007, and guide roller 3 2010, and the limiting constraints of guide frame 2004, guide bracket 1 2006, and guide bracket 2 2009, it achieves precise and coordinated adjustment of the spray device's height and pitch angle. Specifically, mounting bracket 1 20 serves as the fixed base for the motor and winding roller 2002. The first motor 2001 outputs power to drive the winding roller 2002 to rotate, generating longitudinal traction force by winding or releasing the pull line 2003. The pull line 2003 sequentially passes around guide roller 1 2005, embeds itself in guide frame 2004 to ensure horizontal positioning, guide roller 2 2007 is fixed by guide bracket 1 2006 and its inner wall limiting block 2008 constrains the lateral displacement of the pull line 2003, and guide roller 3 2010... The vertical movement path of the end of the pull line 2003 is guided by the guide frame 2009, forming a "three-point guide + hard limit" transmission system for the pull line 2003. This system ultimately transmits the tension to the lifting ring 2011, driving the rotating rod 3004 to rise and fall and control the pitch angle. When the pull line 2003 tightens, the lifting ring 2011 lifts the rear end of the rotating rod 3004, causing the nozzle to press down. Conversely, when the pull line 2003 is released, the nozzle pitch angle increases. The limiting block 2008 of the guide frame 2006 and the rigid support of the guide frame 2009 together limit the swing range of the rotating rod 3004 within 180°, avoiding overload risks. This design separates the tension transmission and path constraint functions through modular guide components. Compared to the traditional single pulley block structure, the height adjustment accuracy is improved to ±0.01 meters, and the wear rate of the pull line 2003 is reduced. It also simplifies the maintenance process, requiring only periodic checks of the guide roller's rotational flexibility.

[0022] A support plate 1002 is fixedly connected to the surface of the upright 1001, an extension rod 1003 is slidably connected to the inner wall of the upright 1001, a connecting plate 1005 is fixedly connected to the top of the extension rod 1003, and an electric telescopic rod 1004 is fixedly connected to the surface of the support plate 1002.

[0023] The upright pole 1001, support plate 1002, extension rod 1003, connecting plate 1005, and electric telescopic rod 1004 constitute the core components of the primary lifting mechanism. Their function is to achieve rapid coarse height adjustment of the sprinkler system through the linear drive of the electric telescopic rod 1004. The upright pole 1001 serves as the fixed main body, and the support plate 1002 welded to its surface provides a rigid mounting base for the electric telescopic rod 1004, ensuring stable transmission of driving force. The telescopic rod end of the electric telescopic rod 1004 is fixedly connected to the connecting plate 1005. When the electric telescopic rod 1004 is activated, it directly pushes or pulls the extension rod 1004. 03 The system can be vertically raised and lowered in the slide rails on the inner wall of the upright 1001. For example, it can raise the sprinkler system from a base height of 3 meters to 8 meters within 10 seconds to deal with dust in high-rise buildings. At the same time, the connecting plate 1005 serves as the lifting terminal support platform and is rigidly connected to the steering unit 30 to transmit the lifting thrust. This structure ensures that there is no swaying during the lifting process through the precise sliding fit between the inner wall of the upright 1001 and the extension rod 1003. The double-sided reinforcing rib design of the support plate 1002 can withstand the bending moment brought by the maximum thrust of the electric telescopic rod 1004 and prevent the upright 1001 from deforming. Compared with the traditional screw lifting mechanism, the speed is increased and the energy consumption is reduced.

[0024] The surface of the upright 1001 is fixedly connected to the limit frame 1006, and the telescopic rod end of the electric telescopic rod 1004 is fixedly connected to the connecting plate 1005.

[0025] The limiting frame 1006, fixedly connected to the surface of the upright 1001, forms a dual safety and guiding mechanism for the lifting mechanism through a rigid connection between the extension rod end of the electric telescopic rod 1004 and the connecting plate 1005. The limiting frame 1006, acting as a rigid stroke constraint component, has an internal groove that slides into the water hose 3007. When the electric telescopic rod 1004 pushes the extension rod 1003 up or down, it limits the lateral displacement of the water hose 3007 to prevent pipe bending and breakage. Simultaneously, when the extension rod 1003 reaches its maximum stroke, the connecting plate 1005 contacts the top of the limiting frame 1006 to form a mechanical stop, preventing the electric telescopic rod 1001 from... 04 Overload damage; while the fixed connection between the telescopic rod end of the electric telescopic rod 1004 and the connecting plate 1005 ensures that the driving force is directly transmitted to the mounting base of the steering unit 30, eliminating the transmission gap of the traditional hinge structure, so that the lifting process is vibration-free. For example, when the rapid lifting of 3 meters to 8 meters is completed within 5 seconds, the limit frame 1006 simultaneously constrains the telescopic path of the water supply hose 3007, ensuring that its bending radius is always ≥ 5 times the pipe diameter. Combined with the linear thrust of the electric telescopic rod 1004, the high efficiency and reliability of the first-level lifting of the sprinkler system are achieved. Compared with the unconstrained telescopic structure, the pipeline life is extended and the lifting and positioning accuracy is improved.

[0026] The pole support mechanism 1 also includes a steering unit 30, which is used to help the spray system turn, thereby expanding the spray range. The steering unit 30 includes a first rotating frame 3001. A second motor 3002 is fixedly connected to the bottom end of the first rotating frame 3001. The output end of the second motor 3002 passes through the first rotating frame 3001 and is fixedly connected to a second rotating frame 3003. A rotating rod 3004 is rotatably connected to the inner wall of the second rotating frame 3003. A groove is opened on the surface of the rotating rod 3004. A water supply hose 3007 is fixedly connected to the inner wall of the groove. A second mounting frame 3005 is fixedly connected to the surface of the rotating rod 3004. A high-pressure nozzle 3006 is fixedly connected to the surface of the second mounting frame 3005.

[0027] The steering unit 30 drives the rotating frame 3003 and the rotating rod 3004 in a dual-degree-of-freedom rotation structure via the second motor 3002. Combined with the dynamic sealing design of the groove-embedded water supply hose 3007, it achieves horizontal and pitch dual-axis steering of the high-pressure nozzle 3006 to expand the spray coverage area. The rotating frame 3001 serves as a steering base and is fixed to the top of the extension rod 1003. The output shaft of the second motor 3002 installed at its bottom passes through the base and is rigidly connected to the rotating frame 3003, driving the latter to rotate horizontally around the axis of the upright. The rotating rod 3004 is pivotally connected to the rotating frame 3003 via a bearing, allowing it to pitch around its own axis. The water supply hose 3007 is embedded in the longitudinal groove on the surface of the rotating rod 3004, fixed by a clamp, and protected by the side wall of the groove to avoid mechanical collision damage. One end of the water supply hose 3007 is connected to an external water source, and the other end extends to the mounting frame 3005 and connects to it. The high-pressure nozzle 3006 is directly connected, forming a closed water circuit. When the second motor 3002 starts, the rotating frame 3003 drives the rotating rod 3004 and the nozzle to rotate horizontally, for example, in 15° increments per minute. At the same time, the rotating rod 3004 is pulled up and down by the pull wire 2003 of the winding mechanism 2, realizing bidirectional adjustment of the spray direction, such as a combination positioning of 90° to the left and 30° downward. The water supply hose 3007 embedded in the groove adopts a spiral armored reinforcement layer. When the rotating rod 3004 moves in both directions, the length change is compensated by the expansion and contraction of the corrugated section. The bending radius is always ≥8 times the pipe diameter, ensuring no leakage after multiple rotation tests. The mounting frame 3005 and the high-pressure nozzle 3006 can be connected by a quick-release flange, supporting nozzle replacement within 5 minutes. The entire steering unit 30 achieves spherical space coverage with horizontal-tilt linkage through modular design, improving the dust suppression range and reducing maintenance costs.

[0028] The water delivery hose 3007 passes through the rotating rod 3004 and is fixedly connected to the high-pressure nozzle 3006. The inner wall of the rotating frame 1 3001 is rotatably connected to the rotating frame 2 3003.

[0029] The through-type fixed connection between the water supply hose 3007, the rotating rod 3004, and the high-pressure nozzle 3006, as well as the rotational cooperation between the rotating frame 1 3001 and the rotating frame 2 3003, jointly construct a coordinated mechanism for dynamic sealed water supply and horizontal steering. The water supply hose 3007 passes through the internal groove of the rotating rod 3004 and extends to the mounting frame 2 3005, directly connecting with the high-pressure nozzle 3006, forming a closed water circuit without intermediate joints. When the rotating rod 3004 is pulled and swung by the winding mechanism 2, the hose adapts to the angle change through the elastic deformation of the armor layer. At the same time, the nylon slider on the inner wall of the groove constrains the lateral displacement of the hose, ensuring that the bending radius is ≥8 times the pipe diameter, avoiding cracking and leakage; the inner wall of the rotating frame 1 3001 passes through the internal groove of the rotating rod 3004 and extends to the rotating frame 2 3005, directly connecting with the high-pressure nozzle 3006, forming a closed water circuit without intermediate joints. The cross roller bearing is rotatably connected to the outer wall of the second rotating frame 3003. Driven by the second motor 3002, it achieves a horizontal 180° limit rotation. For example, it takes 10 seconds to rotate 90°. The second rotating frame 3003 integrates a grease chamber, which continuously supplies oil to the bearing through a capillary oil circuit, reducing the coefficient of friction to below 0.01 and ensuring that the torque fluctuation is ≤5% after 50,000 rotations. The water supply hose 3007 deflects synchronously with the rotating rod 3004 when the rotating frame rotates. Its armor layer slides in contact with the polytetrafluoroethylene wear-resistant bushing on the inner wall of the first rotating frame 3001 to prevent rotational friction damage. This design reduces the leakage risk of traditional split-type rotary joints and achieves stepless precise positioning of the spray system with horizontal-pitch linkage.

[0030] The surface of the rotating frame 3001 is fixedly connected to the extension rod 1003, and the surface of the water supply hose 3007 is slidably connected to the inner wall of the limiting frame 1006.

[0031] The rigid connection between the rotating frame 3001 and the extension rod 1003, and the sliding fit between the water supply hose 3007 and the inner wall of the limiting frame 1006, together achieve the dynamic coordination of the spray system's lifting, turning, and water supply: the rotating frame 3001 is fixed to the top of the extension rod 1003 by flange bolts, serving as the bearing base of the turning unit 30, ensuring stable transmission of torque when the second motor 3002 drives the rotating frame 3003 to rotate horizontally, while simultaneously allowing the overall height of the spray system to adjust synchronously with the lifting of the extension rod 1003; the water supply hose 3007 penetrates the polytetrafluoroethylene wear-resistant groove on the inner wall of the limiting frame 1006. When the electric telescopic rod 1004 drives the extension rod 1003 to rise and fall, the hose slides longitudinally along the chute. Its lateral deviation is constrained by the U-shaped guide groove of the limit frame 1006, ensuring that the bending radius of the hose is always ≥8 times the pipe diameter. Food-grade grease is pre-coated in the chute to reduce the wear rate of the hose armor layer. Combined with the horizontal rotation of the rotating frame 3001, a three-dimensional motion compatibility of "vertical lifting + horizontal turning + pipeline following" is formed. For example, when the sprinkler system rises from 3 meters to 10 meters and rotates horizontally by 90°, the water supply hose 3007 smoothly expands and contracts within the limit frame 1006 to compensate for the 5-meter length change without leakage or twisting.

[0032] The bottom end of the lifting ring 2011 is fixedly connected to the rotating rod 3004. Two guide frames 2004 are provided, and the two guide frames 2004 are fixedly connected to the inner walls of the support plate 1002 and the connecting plate 1005, respectively.

[0033] The rigid connection between the lifting ring 2011 and the rotating rod 3004, along with the layered guiding design of the double guide frame 2004, achieves precise control of the spray device's lifting and pitching linkage through mechanical coupling and path constraints. The bottom end of the lifting ring 2011 is rigidly fixed to the rotating rod 3004 via flange bolts, directly transmitting the traction force of the wire 2003 of the winding roller 2002 to the rear end of the rotating rod 3004. When the first motor 2001 drives the winding roller to tighten the wire 2003, the lifting ring 2011 generates a vertically upward lifting torque, forcing the rotating rod 3004 to pitch downwards around its pivot point with the rotating frame 3003. Conversely, when the wire 2003 is released, the nozzle swings back at an increased pitch angle due to gravity. This rigid connection structure eliminates the gap error of traditional hinge transmission. The two guide frames 2004 are respectively welded to the support plate 1. The bottom of 002 and the top inner wall of the connecting plate 1005 form a double guide layer. After the pull wire 2003 is led out from the winding roller 2002, it first passes through the guide roller 2005 in the lower guide frame 2004 to achieve initial horizontal positioning, and then passes through the guide roller 2005 in the upper guide frame 2004 to correct the path. This ensures that the pull wire 2003 always moves vertically along the axis of the pole 1001 during the lifting and lowering process. At the same time, the double guide frame 2004 structure shares the tension fluctuation of the pull wire 2003, avoiding deformation of the guide roller caused by stress concentration at a single point. With the dynamic displacement of the connecting plate 1005 when the electric telescopic pole 1004 is raised and lowered, the distance between the upper and lower guide frames 2004 is adaptively adjusted to maintain the continuity of the guide path of the pull wire 2003, so that the pitch angle adjustment linearity of the spray device within a height range of 10 meters is maintained.

[0034] The bottom end of conductor frame 1 2006 is fixedly connected to the top end of extension rod 1003, and the bottom end of conductor frame 2 2009 is fixedly connected to rotating rod 3004.

[0035] The design of wire guide frame 1 2006 being fixedly connected to the top of extension rod 1003 and wire guide frame 2 2009 being rigidly fixed to rotating rod 3004 achieves precise control of the transmission path of wire guide 2003 through staged guidance and limiting constraints. Wire guide frame 1 2006, as the primary guide component, has its bottom end welded and fixed to the top of extension rod 1003. When the electric telescopic rod 1004 drives the lifting and lowering, the inner wall limiting block 2008 constrains the lateral displacement of wire guide roller 2 2007, ensuring the wire guide 2003 is lifted... The initial section moves vertically along the axis of the upright 1001; the second guide frame 2009 serves as a secondary guide terminal, with its bottom end connected to the flange of the rotating rod 3004. When the winding roller 2002 winds up and unwinds the pull line 2003, the end of the pull line 2003 is strictly aligned with the traction direction of the lifting ring 2011 by the third guide roller 2010. At the same time, the pitch angle of the rotating rod 3004 is strictly limited to no more than 180°. The dual-stage guide mechanism enables the spray height adjustment accuracy to reach ±0.01 meters, and improves the stability of pitch angle control.

[0036] Working principle: During installation, the user first fixes the pre-assembled pole mechanism 1 to the ground using the mounting plate 10, and quickly anchors it with expansion bolts, eliminating the on-site assembly steps required by traditional equipment. After startup, the electric telescopic pole 1004, acting as the primary lifting mechanism, pushes the extension rod 1003 to rise and fall vertically within the pole 1001, achieving rapid coarse height adjustment of the sprinkler system, for example, from a foundation height of 3 meters to 8 meters to cover high-rise dust. Subsequently, the first motor 2001 drives the winding roller 2002 to wind and unwind the cable 2003, which is then lifted by the lifting ring 2002. 11. A longitudinal traction force is applied to the rotating rod 3004, which, in conjunction with the three-point guide layout of guide roller 1 2005, guide roller 2 2007, and guide roller 3 2010, precisely fine-tunes the nozzle height and simultaneously controls the pitch angle. When the pull cable 2003 is tightened, the rear end of the rotating rod 3004 is lifted, and the high-pressure nozzle 3006 tilts downward to a maximum pitch angle of 90° to suppress dust on the ground. When the pull cable 2003 is released, the rotating rod 3004 swings back under the action of gravity, and the nozzle pitch angle gradually increases, but is limited by the guide roller bracket 2 2009 and the limiting block 200. The mechanical constraints of the 8-axis limit the angle adjustment range strictly to within 180°, from 90° downwards to 90° upwards, avoiding the overshoot risk of traditional hinge structures. Horizontally, the second motor 3002 drives the rotating frame 3003, causing the rotating rod 3004 and the nozzle to rotate 180°, expanding the lateral coverage. The water delivery hose 3007, embedded in the groove of the rotating rod 3004, adopts a spiral armored structure, adapting to length changes through its own expansion and contraction during the lifting and rotation of the rotating rod 3004, while maintaining smooth water flow. Its bending radius is always ≥5 times the pipe diameter to prevent cracking. Throughout the process, the dual-stage lifting mechanism electric telescopic rod 1004 and winding roller 2002 work in shifts. In the coarse adjustment stage, the electric telescopic rod 1004 is used first for quick positioning. In the fine adjustment stage, the winding mechanism 2002 is switched to calibrate with an accuracy of 0.01 meters. Combined with the angle-height coupling algorithm, the nozzle position offset is automatically compensated. For example, when the actual height decreases by 0.5 meters due to a 30° nozzle tilt angle, the system immediately reverses and retracts the winding cable 2003 to raise it by 0.5 meters to ensure the stability of the preset coverage radius. Finally, through the linkage of three degrees of freedom of height, pitch, and horizontal, the spray system can be dynamically adjusted within a height range of 10 meters, forming a three-dimensional dust suppression net with a 180° longitudinal fan shape and a 180° transverse ring trajectory. Compared with traditional fixed equipment, the dust settling efficiency is improved by 40%. Moreover, due to the modular pre-installation and quick-release interface design, the water supply hose 3007 and the high-pressure nozzle 3006 adopt quick-change connectors, shortening the maintenance time.
