Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a dust suppression spray device for building construction. Background Technology

[0002] During construction, earthwork excavation disturbs and breaks up the soil, generating a large amount of dust; the loading, unloading, and stacking of building materials also produce dust; and during concrete mixing, dust escapes from the feed inlet, discharge outlet, and gaps in the mixing drum through the mixing tank. Traditional dust suppression methods have limitations: water spraying is ineffective and wastes water; using dust nets is inconvenient, costly, easily damaged, and causes secondary pollution.

[0003] As people place increasing emphasis on environmental protection and health and safety, construction companies are facing increasingly stringent dust control requirements. Whether it's during project bidding by construction companies or during on-site inspections by government regulatory departments, clear indicators and requirements for dust control are being set. To meet the demands of market competition and avoid penalties for dust pollution, construction companies urgently need efficient, convenient, and economical dust prevention measures.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This dust suppression spray device for construction uses an internal spray mechanism to draw in dust before spraying it for dust suppression. This allows the water mist to precisely target dust particles, improving water resource utilization. During the dust suppression process, some larger water droplets with attached dust particles settle into a collection tank at the bottom of the device under gravity. After simple filtration, this water can be pumped back to the spray nozzles for further dust suppression. This recycling method further reduces the demand for fresh water resources, achieving highly efficient water resource utilization.

[0016] 2. This dust suppression spray device for construction uses an external spray mechanism. The combination of the external and internal spray mechanisms improves dust suppression efficiency. The external spray mechanism reduces the amount of dust entering the construction site and near dust sources, thus reducing the workload of the internal spray mechanism. At the same time, the precise handling of dust sources by the internal spray mechanism compensates for the shortcomings of the external spray mechanism in local dust suppression, ensuring effective dust control throughout the entire construction process.

[0017] 3. This dust suppression spray device for construction uses a synchronous adjustment mechanism and dust sensors for detection. This allows the suction direction of the inner spray mechanism to be precisely aligned with the direction of dust concentration, and also enables the outer spray mechanism to perform oscillating spraying. This provides all-round and efficient dust suppression, helping to reduce the pollution of the surrounding environment caused by construction and protecting the living environment and air quality of nearby residents.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Example 1: See Figures 1-4 The present invention provides a technical solution: a dust suppression spray device for construction, comprising a base 1, an inner spray mechanism 2 fixedly connected to the upper surface of the base 1, an outer spray mechanism 3 fixedly connected to the top of the inner spray mechanism 2, and a synchronous adjustment mechanism 4 fixedly connected to the bottom of the outer spray mechanism 3, and further comprising:

[0046] The internal spray mechanism 2 includes a bracket 201, which is fixedly connected to the top of the base 1. A first motor 202 is fixedly connected inside the bracket 201. An impeller 203 is fixedly connected to the output end of the first motor 202. An air inlet slot 204 is snapped onto the outer surface of the impeller 203 through a slot. A connecting slot 205 is fixedly connected to the bottom of the air inlet slot 204 through a slot through a hole. A first locking block 206 is fixedly connected to the bottom of the connecting slot 205. A first housing 207 is snapped onto the outer surface of the first locking block 206. An arc-shaped flexible baffle 208 is snapped onto the inside of the slot of the first housing 207.

[0047] The internal spray mechanism 2 also includes a second motor 209. The bottom of the second motor 209 is fixedly connected to the top of the first housing 207. The output end of the second motor 209 is fixedly connected to a first connecting rod 210. The inside of the first connecting rod 210 is rotatably connected to a first rotating shaft 211 through a through hole. The outer surface of the first rotating shaft 211 is rotatably connected to a second connecting rod 212. The right end of the second connecting rod 212 is rotatably connected to a second rotating shaft 213. The top of the second rotating shaft 213 is fixedly connected to a triangular locking block 214, which engages with the bottom of the air inlet slot 204. The inside of the first housing 207 is fixedly connected to a baffle plate 215 and a slide slot 216. The bottom of the first housing 207 is engaged with a collection slot 218 through a slot. The outer surface of the collection slot 218 is fixedly connected to a handrail 217. The bottom of the first housing 207 is fixedly connected to a grille 219.

[0048] The connecting groove 205 and the arc-shaped flexible baffle 208 fully cover the slot opened at the top of the first housing 207. The extreme positions of the first connecting rod 210 and the second connecting rod 212 are in contact with the outer surface of the connecting groove 205. Three sets of baffles 215 are provided inside the first housing 207. The inner surface of the slide 216 is flush with the inner surface of the collection tank 218. Multiple sets of atomizing nozzles are fixedly connected inside the first housing 207. By setting up the internal spray mechanism 2, dust is sucked into the first housing 207 and then sprayed to suppress dust, so that the water mist can accurately act on the dust particles, improving the utilization rate of water resources. During the dust suppression process, some larger water droplets with dust particles attached will settle into the collection tank 218 at the bottom of the mechanism under the action of gravity through the slide 216. After simple filtration, this water can be pumped back to the spray nozzle for spray dust suppression. Through this recycling method, the demand for fresh water resources is further reduced, and the efficient utilization of water resources is achieved.

[0049] The working principle of this embodiment is as follows: When using this dust suppression spray device for construction, the first motor 202 starts rotating, driving the impeller 203 to rotate. The second motor 209 starts rotating, driving the first connecting rod 210 to rotate, and through the first rotating shaft 211, driving the second connecting rod 212 to rotate. The second connecting rod 212, through the second rotating shaft 213 and the triangular locking block 214, drives the air inlet slot 204 to rotate. Since the air inlet slot 204 is engaged with the impeller 203, affecting their respective rotations, the impeller 203 rotates and draws dust through the air inlet slot 204. The dust enters the first housing 207 through the connecting groove 205. As the connecting groove 205 rotates with the air inlet groove 204, the arc-shaped flexible baffle 208 is pushed to rotate by the first locking block 206, thus sealing the upper surface of the first housing 207. The dust entering the first housing 207 is atomized and settled by the atomizing nozzle. Multiple sets of baffles 215 increase the reaction time and guide the settled dust through the slide 216 into the collection tank 218 for collection. Pulling the handle 217 realizes the post-processing of the collected dust, and the air is discharged from the first housing 207 through the grille 219.

[0050] Example 2: Please refer to Figures 5-6Based on Embodiment 1, the present invention provides a technical solution: the external spraying mechanism 3 includes a first annular column 301, which is fixedly connected to the top of the bracket 201. A second annular column 302 is snapped onto the inner surface of the first annular column 301. A top plate 303 is fixedly connected to the top of the second annular column 302. A rectangular column 327 and a first pushing assembly 3001 are fixedly connected to the top of the top plate 303. A circular column 328 is rotatably connected to the top of the rectangular column 327 via a rotating shaft. A second housing 309 is fixedly connected to the top of the circular column 328. The first pushing assembly 3001 includes a first rotating shaft connecting block 304, which is fixedly connected to the top of the top plate 303. A first connecting block 305 is rotatably connected to the outer surface of the rotating shaft of the first rotating shaft connecting block 304. A first hydraulic pump 306 is fixedly connected to the top of the first connecting block 305. A second hydraulic pump 306 is fixedly connected to the output end of the first hydraulic pump 306. A connecting block 307 has a second rotating shaft connecting block 308 rotatably connected to its interior via a through hole. The top of the second rotating shaft connecting block 308 is fixedly connected to the outer surface of the second housing 309. A third motor 311 is fixedly connected inside the second housing 309, and a fan blade 310 is fixedly connected to the output end of the third motor 311. A third annular column 312 is fixedly connected to the top of the second housing 309, and a second pushing assembly 3002 is fixedly connected to the outer surface of the third annular column 312. The second pushing assembly 3002 includes a third connecting block 314, and the third connecting block 314 is connected to the third annular column 3002. The outer surface of column 312 is fixedly connected to a second hydraulic pump 315, the top of the third connecting block 314 is fixedly connected to a fourth connecting block 316, the outer surface of the fourth connecting block 316 is fixedly connected to a fourth annular column 313, the outer surface of the fourth annular column 313 is fixedly connected to a sixth connecting block 318, the bottom of the sixth connecting block 318 is fixedly connected to a limit rod 319, the outer surface of the limit rod 319 is slidably connected to a fifth connecting block 317, the fifth connecting block 317 is fixedly connected to the outer surface of the third annular column 312, and the top of the third annular column 312 is fixedly connected to a limit rod 319. An adjustment assembly 3003 is fixedly connected. The adjustment assembly 3003 includes a third rotating shaft connecting block 320, which is fixedly connected to the top of the third annular column 312. The outer surface of the rotating shaft of the third rotating shaft connecting block 320 is rotatably connected to a first rotating rod 321. The outer surface of the rotating shaft of the first rotating rod 321 is rotatably connected to a first right-angle baffle 322 and a second right-angle baffle 323. The inner surfaces of the first right-angle baffle 322 and the second right-angle baffle 323 are rotatably connected to a fourth rotating shaft connecting block 324 and a retaining connecting block 325 via a rotating shaft. The retaining connecting block 325 has a first nozzle 326 inside it.

[0051] The top of the first annular column 301 and the bottom of the second annular column 302 are fixedly connected with annular rubber blocks. Two sets of the first pushing component 3001 are fixedly connected to the outer surface of the second housing 309. Two sets of the second pushing component 3002 are symmetrically arranged on the outer surface of the third annular column 312. Six sets of the adjusting component 3003 are symmetrically arranged on the top of the third annular column 312. By setting the external spraying mechanism 3, the internal spraying mechanism 2 and the external spraying mechanism 3 work together to improve dust suppression efficiency. The external spraying mechanism 3 reduces the amount of dust entering the construction site and near the dust generation source, reducing the workload of the internal spraying mechanism 2. At the same time, the precise treatment of the dust source by the internal spraying mechanism 2 makes up for the shortcomings of the external spraying mechanism 3 in local dust suppression, ensuring that dust is effectively controlled throughout the entire construction process.

[0052] The working principle of this embodiment is as follows: When using this dust suppression spray device for construction, the third motor 311 starts rotating, driving the fan blades 310 to rotate. The water mist sprayed from the first nozzle 326 is pushed into the air by the wind force to settle. When angle adjustment is required, the first hydraulic pump 306 starts and pushes the second housing 309 to rotate upward around the rotating shaft on the outer surface of the circular column 328 through the second connecting block 307 and the second rotating shaft connecting block 308, thereby adjusting the wind angle. The other set of first pushing components 3001 provides auxiliary stabilization adjustment. When the spray range needs to be adjusted by adjusting the angle of the first nozzle 326, the second hydraulic pump 315 starts to compress the air. The limiting rod 319 slides through the through hole inside the fifth connecting block 317, causing the fourth annular column 313 to move downward. The first right-angle baffle 322 and the second right-angle baffle 323 are pressed and rotate around the axis of the fourth rotating shaft connecting block 324. Due to the restriction of the rotation of the first rotating rod 321 around the axis of the third rotating shaft connecting block 320, the first right-angle baffle 322 and the second right-angle baffle 323 are pressed and rotate around the axis of the fourth rotating shaft connecting block 324, while rotating around the axis of the top of the first rotating rod 321. This causes the sleeve connecting block 325 to flip outward around the axis of the sleeve connecting block 325, which in turn causes the first nozzle 326 to flip outward, thereby expanding the spray range. The second hydraulic pump 315 retracts when stretched.

[0053] Example 3: Please refer to Figures 7-9Based on Embodiments 1 and 2, the present invention provides a technical solution: the synchronous adjustment mechanism 4 includes a dust sensor 401, which is engaged with the outer surface of the air inlet slot 204. An arc-shaped column 402 is fixedly connected to the bottom of the second rotating shaft 213. A slot connecting block 403 and a first arc-shaped locking block 405 are fixedly connected to the bottom of the air inlet slot 204. An electromagnet 404 is engaged inside the slot connecting block 403 via a slot. The first arc-shaped locking block 405 is engaged with an annular slot on the top of the first housing 207. A third hydraulic pump 406 is fixedly connected inside the first arc-shaped locking block 405 via a through hole. A second arc-shaped locking block 405 is fixedly connected to the output end of the third hydraulic pump 406. 7. The second arc-shaped locking block 407 engages with the annular groove on the top of the first housing 207. The top of the bracket 201 is fixedly connected to the fourth motor 408 and the fourth hydraulic pump 413. The output end of the fourth motor 408 is fixedly connected to the first gear 409. The outer surface of the first gear 409 is connected to the second gear 411. The inside of the second gear 411 is slidably connected to the nail-shaped rotating rod 410 through a through hole. The top of the nail-shaped rotating rod 410 is fixedly connected to the bottom of the top plate 303. The output end of the fourth hydraulic pump 413 is fixedly connected to the first sleeve 412. The outer surface of the second gear 411 is connected to the third gear 414. The third gear 414 is fixedly connected to the bottom of the top plate 303.

[0054] The top of the second gear 411 is a complete gear and the bottom is an incomplete gear. The first ferrule 412 is in contact with the bottom of the second gear 411. Two sets of dust sensors 401 are attached to the outer surface of the air inlet slot 204. By setting a synchronous adjustment mechanism 4 and using the dust sensors 401 for detection, the suction direction of the inner spray mechanism 2 is precisely adjusted to match the direction of dust density, and the outer spray mechanism 3 is prompted to perform oscillating spraying, which reduces dust in an all-round and efficient manner, helps to reduce the pollution of the surrounding environment caused by construction, and protects the living environment and air quality of the surrounding residents.

[0055] The working principle of this embodiment is as follows: When using this dust-proof spray device for construction, the dust sensor 401 detects the dust. If the dust content increases, the electromagnet 404 pushes the arc-shaped column 402 downward, causing the second rotating shaft 213 to move downward and the triangular locking block 214 to move out of the slot, causing the power of the air inlet slot 204 to fail and stopping the second motor 209. At this time, the third hydraulic pump 406 pushes the second arc-shaped locking block 407 downward to tightly engage with the slot at the top of the first housing 207. The friction plate of the second arc-shaped locking block 407 stops the rotation of the air inlet slot 204. After the friction plate is worn out, the third hydraulic pump 406 can move upward to remove the second arc-shaped locking block 407 out of the slot for replacement. After the angle of the air inlet slot 204 is fixed... The fourth motor 408 rotates, driving the first gear 409 to rotate. The first gear 409 drives the second gear 411 to rotate, and the second gear 411 drives the third gear 414 to rotate. The third gear 414 drives the external spray mechanism 3 to rotate, causing it to face the side with higher dust content. After facing the side, dust is sprayed through the first nozzle 326 to suppress dust. The fourth motor 408 stops rotating, achieving fixed spraying. When swing spraying is required, the fourth hydraulic pump 413 pushes the first ferrule 412 upward, moving it upward so that the gear connection part is replaced by the incomplete gear part of the second gear 411. At this time, the fourth motor 408 rotates, driving the external spray mechanism 3 to swing, achieving swing spraying.
