[0010] Compared with the prior art, the beneficial effects of this utility model are: This novel dust suppression device for public works construction utilizes a combination of connecting pipes, a fixed plate, a spring, a rotating box, a water spray pipe, a mounting ring, a spray pipe, a spring, a bottom ring, a nozzle, a mounting cover, and a dispersion plate. Water is pumped into the mounting pipe via a water pump, flowing through the connecting pipe into the rotating box. The water then enters the spray pipe, compressing the spring and causing it to move upwards. This, in turn, reverses the mounting cover, positioning the nozzle inside the dispersion plate and allowing it to spray water mist. The water flow in the mounting pipe impacts the drive plate, rotating the connecting rod and causing the gear to mesh with the gear ring, which in turn rotates the rotating box, twisting the spring. When the gear and gear ring are not meshing, the spring's twisting motion returns the rotating box to its original position, creating a reciprocating motion that expands the spray range and improves performance.

[0014] Please see Figure 1-5 This utility model provides a technical solution: a novel dust suppression device for public works construction, comprising: an installation pipe 1, with a fixing frame 4 fixedly installed on the outer side of the installation pipe 1; a protective mechanism 2, located on the outer side of the installation pipe 1, the protective mechanism 2 comprising a connecting pipe 201, a fixing plate 202, a spring 203, a rotating box 204, a water spray pipe 205, an installation ring 206, a spray pipe 207, and a bottom ring 209; an opening is provided on the outer side of the installation pipe 1, the connecting pipe 201 is fixedly installed in the opening, and the fixing plate 202 is fixedly installed on the outer side of the connecting pipe 201. A rotating box 204 is rotatably mounted on the outer side of plate 202. A spring 203 is fixedly mounted on the inner side of rotating box 204. The spring 203 is fixedly mounted on the outer side of connecting pipe 201. An installation opening is provided on the outer side of rotating box 204. A water spray pipe 205 is fixedly mounted in the installation opening. An installation ring 206 and a bottom ring 209 are fixedly mounted on the inner side of water spray pipe 205. A spray pipe 207 is provided above the bottom ring 209. A rotary mechanism 3 is located on the outer side of installation pipe 1 and outside of protective mechanism 2, which improves the service life of the device and reduces labor burden and maintenance costs.
[0015] Furthermore, the protective mechanism 2 also includes a spring 208, a nozzle 210, a mounting cover 211, and a dispersion plate 212. A rubber ring is fixedly installed on the outside of the spray pipe 207, and the outside of the rubber ring is in contact with the inside of the water spray pipe 205. A spring 208 is fixedly installed at the bottom of the mounting ring 206, and the spring 208 is fixedly installed on the outside of the spray pipe 207. A nozzle 210 is fixedly installed at the top of the spray pipe 207. A dispersion plate 212 is fixedly installed on the outside of the water spray pipe 205, and a mounting cover 211 is hinged to the inside of the dispersion plate 212. A water pump can be connected through the mounting pipe 1 to pump water into the mounting pipe 1, so that the water enters the rotating box 204 through the connecting pipe 201. The water entering the spray pipe 207 pushes the spring 208 to compress. The spray pipe 207 is moved upward, pushing the mounting cover 211 to reverse, so that the nozzle 210 is positioned inside the dispersion plate 212, causing the nozzle 210 to spray water mist outward. The water flow in the mounting pipe 1 impacts the drive plate 307, causing the connecting rod 304 to rotate, causing the gear 305 to rotate and mesh with the gear ring 306, driving the rotating box 204 to rotate, which in turn twists the spring 203. When the gear 305 and gear ring 306 are not meshing, the spring 203 twists, causing the rotating box 204 to rotate back to its original position, and the rotating box 204 reciprocates, expanding the spray range of the water mist and improving the effect. When not in use, the mounting cover 211 protects the nozzle 210, preventing dust from entering the nozzle 210 and causing blockage, thus reducing damage to the device.
[0016] The rotary mechanism 3 includes a rotating rod 301, a push plate 302, a rotary blade 303, a connecting rod 304, a gear 305, a gear ring 306, and a drive plate 307. An opening is provided on the outer side of the fixing frame 4 and the mounting tube 1. The rotating rod 301 is rotatably mounted within the opening. Four sets of push plates 302 are fixedly mounted on the outer side of the rotating rod 301. The push plates 302 are located on the inner side of the mounting tube 1. A rotary blade 303 is fixedly mounted on the outer side of the rotating rod 301. An installation opening is provided on the outer side of the mounting tube 1, and the installation opening rotates... A connecting rod 304 is installed, and four sets of drive plates 307 are fixedly installed on the outside of the connecting rod 304. The drive plates 307 are located inside the mounting tube 1. A gear 305 is fixedly installed on the outside of the connecting rod 304, and a gear ring 306 is fixedly installed on the outside of the rotating box 204. The rotating rod 301 can be driven to rotate by the water flow impacting the push plate 302, so that the vortex blade 303 rotates to agitate the water mist sprayed from the nozzle 210, so that the water mist enters the construction site, prevents the water mist from dissipating outward, and improves the water mist utilization rate.
[0017] Furthermore, the bottom of the mounting cover 211 fits snugly against the top of the nozzle 210, one end of the spray pipe 207 is conical, and the toothed ring 306 and gear 305 are semi-circular, saving production resources and improving the protective effect.
[0018] Working principle: Water is pumped into the installation pipe 1 via a water pump, and then enters the rotating box 204 through the connecting pipe 201. The water enters the spray pipe 207, compressing the spring 208 and causing the spray pipe 207 to move upwards. This pushes the mounting cover 211 in reverse, positioning the nozzle 210 inside the dispersing plate 212, causing the nozzle 210 to spray water mist. The water flow in the installation pipe 1 impacts the drive plate 307, causing the connecting rod 304 to rotate. This causes the gear 305 to rotate and mesh with the gear ring 306, driving the rotating box 204 to rotate and twisting the mainspring 203. When the gear 305 and gear ring 306 are not meshing, the mainspring 203... 03 The twisting motion drives the rotating box 204 to rotate back to its original position, and the reciprocating motion of the rotating box 204 expands the spray range of the water mist and improves the effect. When not in use, the cover 211 is installed to protect the nozzle 210, prevent dust from entering the nozzle 210 and causing blockage, reduce damage to the device, extend the service life of the device, and reduce labor burden and maintenance costs. The water flow impacts the push plate 302, which drives the rotating rod 301 to rotate, causing the swirl vane 303 to rotate and agitate the water mist sprayed from the nozzle 210, so that the water mist enters the construction site, prevents the water mist from dissipating outward, improves the water mist utilization rate, saves production resources, and improves the protective effect.
[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
