[0025] See also Figure 1-Figure 7The present embodiment provides a spray dust suppression device for a civil engineering construction site, comprising a movable plate 1, the bottom of the movable plate 1 is equipped with pulleys around it, so that the movable plate 1 is more convenient and quick to move, and the top of the movable plate 1 is equipped with a dust suppression component 2, the dust suppression component 2 comprises a water storage tank 201, a support leg 205, a water pipe 204, a water pipe 3 207, a water pump 1 202, and a water pump 2 213. The water storage tank 201 is used to store water required for spraying, and the two sets of support legs 205 are used to support the water collection tank 206, so that the water collection tank 206 is more convenient to use. The water storage tank 201 and the water pump 1 202 are both fixedly connected to the top of the movable plate 1, the water inlet of the water pump 1 202 is connected to the water outlet of the water storage tank 201, and the first outlet of the water pump 1 202 is connected to the water outlet of the water storage tank 201. A water pipe 203 is connected to the water inlet, and a support leg 205 is fixedly connected to the top of the movable plate 1. There are two groups of support legs 205. The tops of the two groups of support legs 205 are fixedly connected to a water collecting tank 206. One end of the water pipe 203 away from the water pump 202 is connected to the water inlet at the bottom of the water collecting tank 206, one end of the water pipe 204 is connected to the second water outlet of the water pump 202, and the other end of the water pipe 204 is connected to the water inlet at the top of the water collecting tank 206. A support rod 211 is fixed inside the water collecting tank 206. The function of the support rod 211 is to support the rotation of the rotating rod 212, so as to facilitate the rotation and use of the rotating rod 212. The internal rotation of the support rod 211 is connected to the rotating rod 212, and one end of the rotating rod 212 is fixedly connected to the impeller 210. The rotation of the impeller 210 can drive the rotating rod 212 to rotate, and then drive the water storage pan 209 to rotate. The other end of the rotating rod 212 is fixedly connected to the water storage pan 209. The outer side of the water storage pan 209 is equipped with a spray head 208. The water storage pan 209 is used to store water resources and provide the five groups of spray heads 208 with the water resources required for spraying. The water inlet of the water pump 213 is connected to the water outlet of the water collecting tank 206. The water outlet of the water pump 213 is connected to the water pipe 3 207. The end of the water pipe 3 207 away from the water pump 213 is connected to the top of the water storage pan 209. The spray heads 208 are arranged in a circular array in five groups. The five groups of spray heads 208 have different directions. The five groups of spray heads 208 have different directions, so the spray heads 208 can spray over a wider range, thereby improving the dust reduction effect. The water outlet of water pipe 1 203 is close to the right side of the bottom end of impeller 210, and the water outlet of water pipe 204 is close to the right side of the top end of impeller 210. The top of the water collecting tank 206 is equipped with a shielding component 3. Since the water outlet of water pipe 1 203 is close to the right side of the bottom end of impeller 210, and the water outlet of water pipe 204 is close to the right side of the top end of impeller 210, when the water outlet of water pipe 1 203 sprays water and the water outlet of water pipe 2 204 sprays water, the impeller 210 can be driven to rotate counterclockwise or clockwise. The shielding component 3 includes a hydraulic cylinder 301, which is fixedly connected to the top of the water collecting tank 206. There are two groups of hydraulic cylinders 301.The inner ends of the two hydraulic cylinders 301 are connected with the force rods 302 through piston sliding. When the two force rods 302 are squeezed by external force, the liquid pressure inside the hydraulic cylinders 301 can be increased, so that the two hydraulic cylinders 301 can push out the two pressure rods 303 respectively. The inner ends of the two hydraulic cylinders 301 are connected with the pressure rods 303 through piston sliding. The outer side of the rotating rod 212 is fixedly connected with a cross block 307. The outer side of the rotating rod 212 is rotatably and slidably connected with a gear 1 306. A cross groove 311 is provided inside the gear 1 306. The cross block 307 and the cross groove 311 are adapted to each other, so that the gear 1 306 can not only rotate with the rotating rod 212, but also slide on the outer side of the rotating rod 212. The gear 1 306 is rotatably connected with the gear 2 305 through the chain 304. There are two groups of gear 2 305. The inside of the two sets of gears 2 305 are fixedly connected with screw rods 309, and the outside of the two sets of screw rods 309 are threadedly connected with sliders 310. The two sets of screw rods 309 can make the two sets of sliders 310 slide up and down with the cooperation of the two sets of I-shaped rods 312. The sides of the two sets of sliders 310 are connected with shielding plates 308 through torsion spring rods. The top of the water collecting tank 206 is fixedly connected with I-shaped rods 312. There are two sets of I-shaped rods 312. The ends of the two sets of I-shaped rods 312 away from the water collecting tank 206 are respectively penetrated and slidably connected with the inside of the two sets of sliders 310. The function of the two sets of shielding plates 308 is to shield the device and then protect the device to prevent some debris and other debris on the construction site from damaging the device. The gear 1 306 is located on the movement trajectory of the two sets of pressure rods 303, and the two sets of force rods 302 are located on the movement trajectory of the two sets of shielding plates 308.

[0026] Working principle: When in use, first push the movable plate 1, and push the movable plate 1 to drive the device to be transported to the site where spray dust reduction is required. At this time, water resources are transported into the water tank 201 through the water inlet on the water tank 201. When the water tank 201 is full of water resources, then turn on the switch on the control panel on the water pump 202 to control the water pipe 203. At this time, water resources are transported from the water tank 201 to the water collecting tank 206 through the water pump 202 and the water pipe 203. At this time, while the water pipe 203 is transporting water to the water collecting tank 206, the pressure of the water impacting upward can make the impeller 210 rotate. When the impeller 210 rotates, it can drive the rotating rod 212 to rotate synchronously. At the same time, when the rotating rod 212 rotates, it can drive the water storage tray 209 fixed thereto to also perform synchronous rotational movement, and under the action of the water pump 213, the water resources transported to the inside of the water collection tank 206 can be transported to the inside of the water storage tray 209 through the water pipe 3 207. At this time, when the water storage tray 209 rotates under the drive of the rotating rod 212, it can also drive the five groups of spray heads 208 to rotate, and the angles of the five groups of spray heads 208 are different. Therefore, when the water storage tray 209 rotates and drives the spray heads 208 to rotate, it can perform spraying operations more comprehensively and widely in areas where spray dust reduction is required. When the rotating rod 212 rotates, since the outer side of the rotating rod 212 is provided with a cross block 307, and the gear 1 3 06 is provided with a cross groove 311 corresponding to the cross block 307 provided on the rotating rod 212, so that the gear 1 306 can not only rotate with the rotating rod 212, but also slide on the outside of the rotating rod 212. When the rotating rod 212 rotates, it can drive the gear 1 306 to rotate. At this time, under the action of the chain 304, the gear 2 305 on both sides of the gear 1 306 can also rotate. When the two groups of gear 2 305 rotate, at this time, the two groups of gear 2 305 respectively drive the two groups of screw rods 309 to rotate. When the two groups of screw rods 309 rotate, at the same time, under the action of the two groups of I-shaped rods 312, the two groups of sliders 310 can only slide up and down. When the two sets of screw rods 309 rotate, the two sets of sliders 310 can slide upward. At the same time, when the two sets of sliders 310 move upward, they can drive the two sets of baffle plates 308 to move upward synchronously. When the two sets of baffle plates 308 move upward, they can squeeze the two sets of force rods 302 respectively. At this time, when the two sets of force rods 302 are subjected to the squeezing force, the liquid pressure inside the two sets of hydraulic cylinders 301 increases, so that the two sets of pressure rods 303 can be squeezed out. When the two sets of pressure rods 303 are squeezed out, they can act on the bottom end of gear 1 306. Under the push of the two sets of pressure rods 303, gear 1 306 can slide upward, so that gear 1 306 is separated from chain 304.When the two sets of gears 305 stop rotating, the two sets of shielding plates 308 no longer slide upward, and the two sets of shielding plates 308 are initially inclined toward opposite sides. Therefore, in the process of sliding upward, the two sets of shielding plates 308 gradually form a V shape, thereby shielding the device to prevent the device from being damaged by stones and other debris falling from the construction site when the device is used, thereby protecting the device. When it is necessary to reset the two sets of shielding plates 308, the second switch on the control panel is pressed to allow the water pump 1 202 to draw water from the water storage tank 2 01 is transported to the water collection box 206 through the water pipe 204. At this time, the water outlet of the water pipe 204 acts on the top of the impeller 210, so that the impeller 210 can rotate in the opposite direction. When the impeller 210 rotates in the opposite direction, it can drive the rotating rod 212 to rotate in the opposite direction, so that the gear 1 306 can rotate in the opposite direction synchronously, so that the two sets of gears 2 305 can also rotate in the opposite direction, and then the two sets of screw rods 309 can rotate in the opposite direction, so that the two sets of shielding plates 308 can slide downward, so that the two sets of shielding plates 308 can be reset. Example

[0027] See also Figure 1-Figure 9The top of the movable plate 1 is equipped with a recovery component 4, and the recovery component 4 includes a bevel gear 403, which is fixedly connected to the outside of the rotating rod 212. The top of the water collecting tank 206 is fixedly connected to a support plate 412, which is used to support the rotational movement of the rotating rod 405, and the support plate 2 413 is used to support the rotational movement of the vortex rod 407. The support plate 3 409 is used to support the rotational movement of the rotating rod 410. The top of the support plate 1 412 is internally rotatably connected to the rotating rod 405, and the end of the rotating rod 405 away from the support plate 1 412 is fixedly connected to the bevel gear 2 404, and the bevel gear 1 403 is meshed with the bevel gear 2 404. The top of the movable plate 1 is fixedly connected to the support plate 2 413, and the internal rotation of the support plate 2 413 is connected to the vortex rod 407. The vortex rod 407 and the rotating rod 405 are connected through a conveyor belt 406. The top of the moving plate 1 is fixedly connected to a support plate three 409, and the support plate three 409 is internally rotatably connected to a rotating rod 410, one end of the rotating rod 410 is fixedly connected to a turbine 408, and the other end of the rotating rod 410 is fixedly connected to an extrusion block 411, and the extrusion block 411 rotates so that the protrusion of the extrusion block 411 drives the water resources of the soft water pipe 414 to be squeezed, so that the water inside the soft water pipe 414 can enter the water storage tank 201, and the two groups of baffle plates 308 are provided with water flow troughs 401 on the opposite sides, and two groups of water flow troughs 401 are provided on one group of baffle plates 308, and the ends of each two groups of water flow troughs 401 are connected to the U-shaped tube 402, and the two groups of U-shaped tubes 402 are connected to the soft water pipe 414, and the soft water pipe 414 is connected to the water collecting tank 206, and the outer side of the soft water pipe 414 is fixedly connected to a hard water pipe, and the extrusion block 411 is close to the top of the soft water pipe 414.

[0028] Working principle: When the two sets of shielding plates 308 form a V shape, the water storage tray 209 rotates to drive the spray heads 208 with different spray angles to rotate. At this time, some water will be sprayed on the two sets of shielding plates 308. If no measures are taken, the water resources sprayed on the two sets of shielding plates 308 will be wasted. Therefore, the water splashed on the two sets of shielding plates 308 can flow along the direction of the water flow grooves 401 through the multiple sets of water flow grooves 401. When the water resources flow down from the multiple water flow grooves 401, they can pass through the two sets of U-shaped pipes 402. There is a soft water pipe 414 connected between the two sets of U-shaped pipes 402, and the soft water pipe 414 is connected to the water storage tank 201. At this time, since the rotating rod 212 can rotate, it can drive the bevel gear 1 403 to rotate as well. Since the bevel gear 1 403 is meshed with the bevel gear 2 404, when the bevel gear 1 403 rotates, the bevel gear 2 404 can also rotate. When the bevel gear 2 404 rotates, the rotating rod 405 can be driven to rotate. At the same time, when the rotating rod 405 rotates, the worm 407 can also rotate under the action of the conveyor belt 406. Since the worm 407 is meshed with the turbine 408, when the worm 407 rotates, the turbine 408 can also rotate. When the turbine 408 rotates, the rotating rod 410 can be rotated. When the rotating rod 410 rotates, the extrusion block 411 can be driven to rotate. Since the extrusion block 411 is located above the soft water pipe 414, the soft water pipe 414 can be squeezed, so that the water flowing into the soft water pipe 414 through the water flow trough 401 can enter the interior of the water storage tank 201, thereby saving water resources.
