[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0025] Reference Figure 1-Figure 4 A dust reduction device for highway bridge construction includes a water barrier 1, a partition 2 is fixedly connected to the top of the water barrier 1, and the partition 2 is used to improve the enclosure effect; a water mist dust reduction mechanism 3 is provided on one side of the partition 2, and the water mist dust reduction mechanism 3 is used for regional dust reduction.

[0026] like Figure 1-Figure 4As shown, by cooperating with the water barrier 1 and the partition 2, the construction area can be fenced during the construction of the highway bridge, which can not only serve as a warning, but also prevent irrelevant personnel from entering the construction area. A water mist dust reduction mechanism 3 is provided on one side of the partition 2. The water mist dust reduction mechanism 3 includes a nozzle 13 provided on the side of the partition 2, and the nozzle 13 is used to spray water mist for regional dust reduction.

[0027] like Figure 1-Figure 4 As shown, a slide groove 4 is provided on one side of the partition 2, and both ends of the partition 2 are fixedly connected to a floodlight strip 5. A limited resistance block 6 is fixedly connected to one side of the partition 2. The water mist dust reduction mechanism 3 also includes a mounting plate 7 slidably installed inside the slide groove 4. The outer wall of the mounting plate 7 is fixedly connected to a spray pipe rack 8. The outer wall of the spray pipe rack 8 is provided with a No. 1 protective groove 9 and a No. 2 protective groove 10. The nozzle 13 is installed inside the No. 1 protective groove 9 and the No. 2 protective groove 10. A No. 1 water spray pipe 11 and a No. 2 water spray pipe 12 are fixedly installed inside the spray pipe rack 8. The nozzle 13 is connected to the No. 1 water spray pipe 11 and the No. 2 water spray pipe 12 through branch pipes respectively. The No. 1 water spray pipe 11 is located at the top of the No. 2 water spray pipe 12. The diameter of the No. 2 water spray pipe 12 is smaller than the diameter of the No. 1 water spray pipe 11. The slide groove 4 provided on the outer wall of the partition 2 makes it convenient to install the mounting plate 7 by sliding. At the same time, a limited resistance block is fixedly connected to one side of the partition 2. 6. The mounting plate 7 can be limited to prevent the mounting plate 7 from being easily displaced and separated from the slide groove 4. The No. 1 protective groove 9 and the No. 2 protective groove 10 can protect the nozzle 13 installed therein, and the position and orientation of the No. 1 protective groove 9 and the No. 2 protective groove 10 can make the nozzle 13 spray water mist upward and downward respectively with the axis of the spray pipe rack 8 as the center, wrapping part of the construction area, increasing the dust reduction area and range, and reducing the diffusion range of construction dust. At the same time, the No. 2 water pipe 12, which is smaller than the No. 1 water pipe 11 in diameter, has a smaller diameter during the liquid supply process of the liquid supply equipment, which can increase the internal liquid pressure and enhance the water mist spraying effect of the nozzle 13. Since the direction of the water mist sprayed by the nozzle 13 connected to the No. 2 water pipe 12 is toward the ground, the dust reduction effect of the water mist on the construction site can be enhanced, avoiding the low-altitude diffusion of dust due to mechanical impact at the construction site.

[0028] like Figure 1-Figure 3As shown, one end of the spray pipe rack 8 is fixedly connected to a three-way metal pipe 16, and the diversion ports of the three-way metal pipe 16 are respectively connected to the No. 1 water spray pipe 11 and the No. 2 water spray pipe 12. One end of the water inlet of the three-way metal pipe 16 is fixedly connected to a quick pipe connector plug 17. The other end of the spray pipe rack 8 is fixedly connected to a hose 18. One end of the hose 18 is connected to the inside of the No. 1 water spray pipe 11, and the other end of the hose 18 is fixedly connected to a quick pipe connector socket 19. The spray pipe rack 8 is in a semicircular shape as a whole, and the No. 1 protective groove 9 and the No. 2 protective groove are connected. 10 is symmetrically arranged with the axis of the spray pipe rack 8 as the center. Through the three-way metal pipe 16 and the hose 18 at both ends of the spray pipe rack 8, the quick pipe connection plug 17 and the quick pipe connection socket 19 can be used to complete the quick connection of the water supply pipeline, so as to facilitate the series connection of the same dust suppression device and the water supply pipe to meet the dust suppression spray liquid supply needs. The quick pipe connection plug 17 and the quick pipe connection socket 19 involved in the utility model are existing devices. After being plugged into each other, water and air can be passed through, and they can be sealed and closed after being separated from each other. They will not be described in detail here.

[0029] like Figure 1-Figure 4 As shown, a protective strip 14 is fixedly connected to the outer wall of the spray pipe rack 8, and a protective frame 15 is fixedly connected inside the protective strip 14. The protective frame 15 is located on the outside of the nozzle 13. The protective strip 14 and the protective frame 15 are an integrated structure. By utilizing the protective strip 14 fixedly connected to the outer wall of the spray pipe rack 8, when the entire device falls over, the protective strip 14 can be used to pre-contact the collision object or the ground, thereby providing protection for the spray pipe rack 8. Moreover, the protective frame 15 fixed inside the protective strip 14 can also protect the nozzle 13 to prevent the protruding parts of the object from hitting the nozzle 13, causing damage to the nozzle 13 and affecting the service life of the entire dust reduction device.

[0030] like Figure 1-Figure 2 As shown, both ends of the water horse 1 are fixedly connected with a connecting rod 20, one end of the water horse 1 is fixedly connected with a drain valve pipe 21, the drain valve pipe 21 is communicated with the inside of the water horse 1, and one side of the water horse 1 is fixedly connected with a liquid injection pipe 22, the liquid injection pipe 22 is communicated with the inside of the water horse 1. Through the connecting rod 20 fixedly connected at both ends of the water horse 1, a rope or a connecting frame can be used to connect and fix the same dust suppression device. The drain valve pipe 21 fixedly connected at one end of the water horse 1 can be used for discharging the liquid inside the water horse 1, and the liquid injection pipe 22 fixedly connected on one side of the water horse 1 can be used to inject liquid into the water horse 1, and the liquid is used to increase the weight of the water horse 1, thereby improving the placement stability of the water horse 1 and at the same time improving the buffering effect of the water horse 1 after being hit.

[0031] like Figure 1-Figure 2 As shown, an air trough 23 is opened inside the partition 2, and a reflective plate 24 is fixedly connected to the side of the partition 2 away from the water mist dust reduction mechanism 3. The air trough 23 opened inside the partition 2 can reduce the wind resistance of the partition 2, and the reflective plate 24 fixedly connected to one side of the partition 2 can reflect light to serve as a warning effect.

During the spraying process, the water mist sprayed by the nozzle 13 in the No. 1 protective groove 9 and the No. 2 protective groove 10 will spread in a C shape, covering part of the construction area. At the same time, according to the scope of the construction area, multiple highway bridge construction sites can be placed. The dust reduction device utilizes the connecting rod 20 fixedly connected at both ends of the water horse 1, and uses ropes or connecting frames to connect and fix the same dust reduction device to form a regional enclosure. After the splicing is completed, the quick pipe connection plug 17 and the quick pipe connection socket 19 of the adjacent water mist dust reduction mechanism 3 are plugged into each other, thereby connecting the water supply pipes of multiple dust reduction devices in series. When the entire device is blown down by strong winds, the protective strip 14 contacts the collision object or the ground in advance to provide protection for the spray pipe rack 8, and the protective frame 15 fixed inside the protective strip 14 can also provide local protection for the nozzle 13 to prevent the protruding parts of the object from hitting the nozzle 13 and causing damage to the nozzle 13.
