TECHNICAL FIELD

[0001] The utility model relates to road construction technical field, specifically is a road construction environmental protection dust falling device. BACKGROUND

[0002] In the road construction process, a large amount of dust will be produced. These dusts not only seriously pollute the surrounding environment, affect the quality of life of the surrounding residents, but also pose a great threat to the health of the on-site staff. Therefore, dust falling treatment becomes an important link indispensable in road construction. In the traditional road construction dust falling mode, the fog gun machine is more widely used. The working principle of the fog gun machine is to atomize water flow with the help of a high-pressure fan, which is equipped with a spraying device inside, can spray water mist up to dozens of meters, and can realize the effects of cooling the road surface, dust removal and clean air by adsorbing dust particles floating in the air through water mist. However, the existing fog gun machine has obvious limitations. The opening is small, and the spraying range is greatly limited when spraying water mist, making it difficult to comprehensively and effectively reduce dust in a large construction area. With the continuous expansion of road construction scale and the increasing of environmental protection standards, the existing fog gun machine has been unable to meet the dust falling needs of actual projects. SUMMARY

[0003] Therefore, in order to solve the above problems, the utility model provides a road construction environmental protection dust falling device, which realizes the expansion or reduction of the spraying area by combining and separating the extension pipe and the spraying pipe, so as to be applied to various construction environments and effectively solve the problem that the fog gun machine cannot be applied to large-area construction.

[0030] As described in the background section, existing road construction dust suppression methods typically use fog cannons. However, because fog cannons have a small opening, they are only suitable for small-scale construction and cannot guarantee overall dust suppression effectiveness when the construction area is large.

[0031] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 and attached Figure 2 The present invention provides the following technical solution: a road construction environmental protection dust reduction device, including a temporary water tank 3, which is mounted on a vehicle body 1 for movement, and casters 2 are mounted on the four corners of the bottom of the vehicle body 1;

[0032] The drain pipe 5 is connected to the bottom of the temporary water tank 3 and the water is pumped into the drain pipe 5 by the water pump 6 for high-pressure transportation.

[0033] The spray pipe 8 is connected at one end to both sides of the outlet end of the drain pipe 5 and is kept rotating or fixed.

[0034] The extension pipe 9 is movably installed on the other end of the spray pipe 8 to maintain connection or separation;

[0035] Several atomizing nozzles 12 are arranged in a straight line on the spray pipe 8 and the extension pipe 9 and are kept in communication with the interior.

[0036] In this embodiment, a water inlet pipe 4 is provided on the top side of the temporary water tank 3, and the drain pipe 5 is a three-way pipe structure. The first end is connected to the inside of the temporary water tank 3, the second end extends vertically upward and is connected to the spray pipe 8, and the third end extends vertically downward and is provided with a drain valve 7 at the end.

[0037] As mentioned above, the purpose of installing a drain valve is to facilitate the rapid drainage of water from the temporary water tank after construction is completed or when construction is not carried out due to rain, so as to facilitate the movement of the device.

[0038] Please refer to the appendix. Figure 2 -Appendix Figure 4 In this embodiment, a vertical support column 10 is provided on the outer side of the vehicle body 1, and a horizontal transition pipe 11 is fixedly installed on the top of the support column 10. The transition pipe 11 is connected to the drain pipe 5, and spray pipes 8 are rotatably provided at both ends of the transition pipe 11.

[0039] Please refer to the appendix. Figure 5 -Appendix 9, In ​​this embodiment, one end of the spray pipe 8 is a connecting part 801. The connecting part 801 is sleeved on the outside of the transition pipe 11 and is connected to the rotating connector 13 to maintain a rotatable connection. A fixing plate 802 is provided on the end of the connecting part 801. Fixing holes 803 are circumferentially distributed on the fixing plate 802. The fixing member 14 passes through any one of the fixing holes 803 and is connected to the through hole of the support column 10 to fix the spray pipe 8. The other end of the spray pipe 8 is a spray part 804. Several atomizing nozzles 12 are arranged in a straight line on the spray part 804. A mounting plate 805 is provided on the end of the spray part 804. The mounting plate 805 is provided with mounting holes 806. A conical sealing part 808 is also provided on the inner wall end of the spray part 804. The conical sealing part 808 is sealed by contact between the elastic member 16 and the ball head screw 15 of the limiting boss 807 on the inner wall of the spray part 804.

[0040] In this embodiment, one end of the extension tube 9 is provided with a first connecting plate 901, and a first connecting hole 902 is provided on the first connecting plate 901. A conical sealing part is provided at the inner wall end of the first connecting plate 901 of the extension tube 9. The sealing is achieved by the contact between the elastic element 16 of the inner wall limiting boss 807 and the ball head screw 15. The other end of the extension tube 9 is provided with a second connecting plate 903, and a second connecting hole 904 is provided on the second connecting plate 903. A support plate 905 is provided on the inner wall of the second connecting plate 903 of the extension tube 9. Through holes 907 are evenly provided on the support plate 905, and a conical top 906 is provided at the center of the support plate 905.

[0041] In this embodiment, the first connecting plate 901 and the first connecting hole 902 correspond to the second connecting plate 903 and the second connecting hole 904, as well as the mounting plate 805 and the mounting hole 806, respectively.

[0042] In this embodiment, the water pump 6 is configured with adjustable power, thereby ensuring that even after the extension pipe 9 is added, the sprayed mist water droplets can still cover a relatively long distance.

[0043] In use, the dust suppression device is first pushed to a suitable position in the construction area by the vehicle body 1, and the entire device is fixed by the casters 2. Then, the water supply pipe 4 of the temporary water tank 3 is connected to the external water source to fill the temporary water tank with water, while the drain valve 7 is closed to prevent direct flow.

[0044] Then, adjust the spray angle and range according to the size of the construction area. When adjusting the angle, simply remove the fixing part 14, then rotate the spray pipe 8 so that the atomizing nozzle 12 at the outer end of the spray pipe 8 is in an appropriate position for spraying. After adjustment, insert the fixing part 14 into the corresponding fixing hole 803 and connect it to the support column 10 (to ensure that the fixing part will not loosen or even fall off during use, the fixing part can be bolted and nut).

[0045] When adjusting the spray range, simply add an appropriate number of extension pipes 9 to the end of the spray pipe 8 according to the length of the spray pipe 8 and the extension pipe 9. When adding extension pipes, first connect the second connecting plate 903 of the extension pipe 9 to the mounting plate 805 of the spray pipe 8, causing the conical head 906 to move the ball-head screw 15 into the spray pipe 8, thereby squeezing the elastic element 16 and separating the ball-head screw 15 from the conical sealing part 808, creating a gap to facilitate liquid flow (see attached diagram). Figure 7As can be seen, the bolts and nuts are then used to fix the pipes through the second connecting hole 904 and the mounting hole 806. To prevent leakage, O-rings can be installed at the ends of the second connecting plate 904 and the mounting plate 805. Then, the extension pipe at the rear end can be installed according to the aforementioned steps. If it is not necessary to expand the spraying range, the extension pipe does not need to be added. At this time, the end of the extension pipe or spray pipe 8 can be firmly pressed against the conical sealing part 808 by the elastic force of the elastic element 16, preventing water from flowing out from the end, thereby ensuring that water is sprayed out from the atomizing nozzle 12 under high pressure to achieve the purpose of dust suppression.

[0046] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
