Description

Technical Field

[0001] This invention relates to the field of construction dust suppression technology, specifically a decentralized spray dust suppression device and its usage method. Background Technology

[0002] Spraying for dust suppression during construction is an effective dust control technology. Its principle is to utilize the microparticles generated by the spray system to rapidly adsorb dust particles of various sizes in the air, thus effectively controlling dust. During construction, spray systems are installed at the perimeter fencing or in the target area. High-pressure water pumps, nozzles, and pipes are used to evenly spray water mist, ensuring that the water mist fully contacts the dust particles in the air.

[0003] The existing patent publication number CN115400523B discloses a construction site dust suppression device that uses a rotating mechanism for multi-range spraying. The device includes a dust collection box with an outer shell. A notch is provided on one side of the shell, and insert plates are provided on both the upper and lower sides of the notch. A connecting column is connected to the top of each insert plate. A spraying device is located at the notch. The spraying device includes a drive assembly, which includes a fixed plate. A back plate is provided on the side of the fixed plate. A connecting plate is attached to one end of a moving plate. An inner cavity is formed at the inner end of the connecting plate. The fixed plate and the inner end of the inner cavity are in a plug-in fit. A water hose is located at the inner end of the inner cavity, and several spray pipes are provided on the side of the water hose. In this construction site dust suppression device that uses a rotating mechanism for multi-range spraying, the rotation of the main gear drives the rotation of two auxiliary gears, which in turn drive the relative rotation of two levers, causing the moving plate to move up and down vertically, changing the spray position of the water hose to achieve dust suppression in different areas of the construction site.

[0004] The aforementioned dust suppression equipment can spray over a wide area during use. However, while the moving plate can move up and down and the water hose can change the spray position, the spray range still needs to be increased, and the protective features of the equipment during use also need to be improved. To address these issues, a decentralized spray dust suppression equipment and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a decentralized spray dust suppression device and its usage method to solve the problems mentioned in the background art.

[0014] In one alternative embodiment: the mounting bracket includes a rotating bar and a mounting plate fixedly connected to the bottom of the rotating bar, the bottom of the protective cover is rotatably connected to the rotating bar, and the bottom end of the mounting plate is fixedly connected to a support base.

[0015] In one alternative embodiment: the guide includes four sets of support rods connected to the top of the support base. Each support rod has a cavity for the traction rope to pass through. The cavity communicates with the inner cavity of the support base. Two sets of guide wheels are rotatably connected to the ends of the support rods. The outer walls of the guide wheels are in contact with the traction rope. Two sets of hook rings are fixedly connected to each set of protective covers. A set of traction ropes is connected to each set of hook rings. The two sets of traction ropes on the same set of protective covers correspond to the two sets of support rods.

[0016] In one alternative: the positioning element includes a lifting plate and several buried rods connected to the bottom of the lifting plate, and the base is provided with a lifting groove for the sliding of the lifting plate, the bottom of the lifting groove being in communication with the outside.

[0017] In one alternative embodiment: the moving component includes a lead screw rotatably connected within a support base; a motor for driving the lead screw to rotate is installed at the bottom of the inner cavity of the support base; a threaded hole on the lifting frame is threaded to engage with the lead screw; the outer wall of the lifting frame is slidably engaged with the inner wall of the support base; two sets of first racks are fixedly connected to the lifting frame; a gear meshing with the first racks is rotatably connected within the support base; and two sets of second racks are fixedly connected to the top of the lifting plate, with the second racks meshing with the gears.

At the same time, driven by the adjustment mechanism, the arc-shaped pipe swings and the end of the arc-shaped pipe rotates in the mounting base. The four sets of arc-shaped pipes work together to carry out decentralized spraying.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

The four sets of arc tubes work together to perform dispersed spraying, and spraying obliquely upwards can cover a wider space, so that the water mist has a larger contact area with the dust particles in the air. In windy conditions, oblique upward spraying can better cope with the influence of wind direction and maintain the dust reduction effect.

[0024] In this invention, the protective cover can protect the arc-shaped pipe, providing effective protection when dust suppression spraying is not in progress, reducing blockage at the water outlet of the arc-shaped pipe, and the moving parts can synchronously adjust the movement of the lifting frame and the positioning parts. When the protective cover is unfolded, the positioning parts position the equipment, facilitating dust suppression spraying operations. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] 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.

[0039] Please see Figures 1-8 In this embodiment of the invention, a decentralized spray dust suppression device includes a support mechanism 100, a protective mechanism 200, and a spray mechanism 400.

[0040] The support mechanism 100 includes a base 101 and a support seat 103 connected to the top of the base 101. The bottom of the base 101 is equipped with casters 102. The casters 102 facilitate the movement of the equipment.

[0041] The spraying mechanism 400 includes a fixed frame 401 and four sets of arc-shaped tubes 403 disposed on the fixed frame 401. The top of the support base 103 is connected to the fixed frame 401 via a fixed rod 104. Both ends of the arc-shaped tubes 403 are rotatably connected to mounting seats 402 mounted on the fixed frame 401. The top of the support base 103 is equipped with an adjustment mechanism 300 for adjusting the swing of the arc-shaped tubes 403. The four sets of arc-shaped tubes 403 work together to perform dust suppression spraying. The adjustment mechanism adjusts the swing of the arc-shaped tubes 403, which can increase the spraying range of the arc-shaped tubes 403.

[0042] The protective mechanism 200 includes a protective cover 203 and a mounting bracket rotatably connected to the bottom of the protective cover 203. The protective cover 203 is connected to a traction rope 205 via a hook ring 204. The traction rope 205 extends into the support base 103 and connects to a lifting frame 108. A guide member for guiding the traction rope 205 is installed on the support base 103. A positioning member for positioning the equipment is installed in the base 101. A moving member for adjusting the relative movement of the lifting frame 108 and the positioning member is installed in the support base 103.

[0043] When the lifting frame 108 is raised, the traction rope 205 is released, and the protective cover 203 can be flipped over. Figure 2 As shown, the protective cover 203 flips open, which facilitates the spraying and dust suppression operation of the arc-shaped tube 403. The guide can guide the traction rope 205 to prevent the movement of the traction rope 205 from affecting the arc-shaped tube 403.

[0044] like Figure 5 As shown, the ends of two adjacent sets of arc-shaped pipes 403 pass through the mounting base 402 and are connected to a bend 406 via a rotary joint. The water inlet end of the bend 406 is connected to a water supply pipe 407. Several nozzles 404 are connected to the arc-shaped pipes 403. A connecting plate 405 is connected to the side of the arc-shaped pipes 403 away from the nozzles 404. Water enters the water supply pipe 407 and can be sent to the arc-shaped pipes 403 through the bend 406 and the rotary joint, and then sprayed out from the nozzles 404.

[0045] like Figure 6 As shown, the adjustment mechanism 300 includes an adjustment seat 301 and a sliding column 302 connected to the top of the adjustment seat 301. A sliding sleeve 303 is slidably connected to the sliding column 302. Four sets of spring telescopic rods 304 corresponding to the arc-shaped tube 403 are hinged to the sliding sleeve 303. A connecting plate 405 is hinged to the end of the spring telescopic rod 304 away from the sliding sleeve 303. The adjustment seat 301 is connected to the top of the support seat 103. Two sets of water wheel covers 308 are provided inside the adjustment seat 301. The water outlet end of the water wheel cover 308 is connected to the water supply pipe 407 through the water outlet pipe 310. A water wheel component is provided inside the water wheel cover 308. An adjustment component for adjusting the reciprocating lifting and lowering of the sliding sleeve 303 is installed on the outer wall of the adjustment seat 301. The water wheel component can be used for water intake. The adjustment component drives the sliding sleeve 303 to reciprocate and lift. The arc-shaped tube 403 can be swung by pulling the spring telescopic rods 304.

[0046] like Figure 6 and Figure 7 As shown, the water turbine component includes a rotating shaft 311 rotatably connected inside the water turbine cover 308. Several blades 312 arranged in a circular array are connected to the rotating shaft 311. A water inlet pipe 309 is installed on the support base 103, with its outlet end connected to the water inlet end of the water turbine cover 308, and the water inlet end of the water turbine cover 308 corresponding to the blades 312. The adjusting component includes a turntable 307. The end of the rotating shaft 311 is fixedly connected to the turntable 307 via a connecting shaft. The connecting shaft is rotatably connected to an adjusting base 301. A connecting rod 306 is rotatably connected to the eccentric portion of the turntable 307 away from the adjusting base 301. A fixing plate 305 is rotatably connected to the end of the connecting rod 306 away from the turntable 307. The bottom of the sliding sleeve 303 is fixedly connected to the fixing plate 305.

[0047] The outlet of the external water supply equipment can be connected to the inlet pipe 309. When water enters through the inlet pipe 309, it can impact the blades 312, thereby causing the blades 312 to drive the rotating shaft 311 to rotate. During the rotation of the rotating shaft 311, the turntable 307 can be driven to rotate through the connecting shaft, thereby driving the fixed plate 305 to rise and fall through the connecting rod 306. The fixed plate 305 drives the sliding sleeve 303 to rise and fall.

[0048] like Figure 2 and Figure 3 As shown, the mounting frame includes a rotating bar 202 and a mounting plate 201 fixedly connected to the bottom of the rotating bar 202. The bottom of the protective cover 203 is rotatably connected to the rotating bar 202, and the bottom end of the mounting plate 201 is fixedly connected to the support base 103. The protective cover 203 can rotate around the rotatable connection point with the rotating bar 202.

[0049] like Figure 3 As shown, the guide includes four sets of support rods 207 connected to the top of the support base 103. Each support rod 207 has a cavity for the traction rope 205 to pass through. The cavity communicates with the inner cavity of the support base 103. Two sets of guide wheels 206 are rotatably connected to the ends of the support rods 207. The outer wall of the guide wheels 206 contacts the traction rope 205. Two sets of hook rings 204 are fixedly connected to each set of protective covers 203. One set of traction ropes 205 is connected to one set of hook rings 204. The two sets of traction ropes 205 on the same set of protective covers 203 correspond to the two sets of support rods 207. The traction rope 205 passes through the cavity and can move stably under the guidance of the guide wheels 206.

[0050] like Figure 8 As shown, the positioning component includes a lifting plate 105 and a plurality of buried rods 106 connected to the bottom of the lifting plate 105. The base 101 is provided with a lifting groove for the sliding of the lifting plate 105, and the bottom of the lifting groove is connected to the outside.

[0051] The height of the lifting plate 105 can be adjusted to adjust the position of the buried rod 106. The buried rod 106 can be placed in the soil or buried underground to temporarily limit and fix the position of the equipment.

[0052] The moving component includes a lead screw 107 rotatably connected within a support base 103, a motor 109 for driving the lead screw 107 to rotate installed at the bottom of the inner cavity of the support base 103, a threaded hole on the lifting frame 108 that is threadedly engaged with the lead screw 107, a sliding fit between the outer wall of the lifting frame 108 and the inner wall of the support base 103, two sets of first racks 110 fixedly connected to the lifting frame 108, a gear 111 rotatably connected within the support base 103 that meshes with the first racks 110, and two sets of second racks 112 fixedly connected to the top of the lifting plate 105, the second racks 112 meshing with the gears 111.

[0053] The motor 109 drives the lead screw 107 to rotate, thereby adjusting the lifting frame 108. When the lifting frame 108 rises, it drives the first rack 110 to rise, which in turn drives the gear 111 to rotate, thereby driving the second rack 112 to fall. The second rack 112 drives the lifting plate 105 to fall, so that when the lifting frame 108 drives the traction rope 205 to lay the line, the buried pole 106 contacts the ground. Conversely, when the lifting frame 108 falls, the lifting frame 108 falls and the lifting plate 105 rises.

[0054] The top of the sliding column 302 is connected to a limiting plate, the outer diameter of which is larger than the outer diameter of the sliding column 302, and the outer diameter of the sliding column 302 is larger than the width of the adjusting seat 301; the sliding sleeve 303 can slide stably up and down on the sliding column 302.

[0055] When the present invention is used, the equipment is moved to the target position, and the rotation of the lead screw 107 is driven by the motor 109. The lifting frame 108 rises, driving the first rack 110 to rise. During the rise, the gear 111 rotates, thereby driving the second rack 112 to fall. The second rack 112 drives the lifting plate 105 to fall, so that when the lifting frame 108 drives the traction rope 205 to release the line, the buried pole 106 contacts the ground and fixes itself to the equipment, causing the traction rope 205 to move towards the side closer to the protective cover 203, and the protective cover 203 to flip away from the side away from the arc tube 403.

[0056] The outlet of the water supply equipment can be connected to the inlet pipe 309. When water enters through the inlet pipe 309, it impacts the blades 312, thereby driving the blades 312 to rotate the rotating shaft 311. During the rotation of the rotating shaft 311, the turntable 307 can be rotated through the connecting shaft, thereby driving the fixed plate 305 to rise and fall through the connecting rod 306. The fixed plate 305 drives the sliding sleeve 303 to rise and fall, and the arc-shaped pipe 403 enters and sprays water. At the same time, during the reciprocating rise and fall of the sliding sleeve 303, the arc-shaped pipe 403 can be pulled to swing through the spring telescopic rod 304. The end of the arc-shaped pipe 403 rotates in the mounting base 402. The four sets of arc-shaped pipes 403 cooperate to perform decentralized spraying.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
