[0002] Municipal engineering generally belongs to the country's infrastructure, and refers to the construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation, lighting and other infrastructure in urban construction. It is an indispensable material basis for the survival and development of cities, and a basic condition for improving people's living standards and opening up to the outside world.

[0003] At present, when using dust suppression spray devices to reduce dust on construction sites, most of them adopt water mist dust reduction. Due to the high dust content on construction sites, the dust in the air can easily clog and damage the atomizing nozzles during use. In order to prevent the dust reduction effect from decreasing, workers are required to replace the damaged atomizing nozzles. However, since most of the atomizing nozzles on the existing dust suppression spray devices are installed on the dust suppression spray devices by screwing, when the atomizing nozzles are damaged and need to be replaced, workers are required to screw and disassemble them, and screw and install new atomizing nozzles. When a large number of atomizing nozzles are damaged and need to be replaced, the continuous and repeated screwing work can easily cause fatigue among the workers, reducing the replacement efficiency of the atomizing nozzles.

[0004] Therefore, it is necessary to provide a dust suppression spray device for municipal engineering to solve the above technical problems. Utility Model Content

The inner part of the shielding frame 10 is fixedly connected with a limit rod 11, and the limit rod 11 movably penetrates the connecting pipe 6 and extends to the inside of the mounting block 7. Two connecting components are provided on the vehicle body 1. By rotating the rubber plug 18, it is separated from one end of the corresponding water pipe 25, and a threaded connection sleeve 14 is installed on the water pipe 25. A new water pipe 25 with several atomizing nozzles 8 installed on the top can be taken out, and the water pipe 25 is connected to the new water pipe 25 through the threaded connection sleeve 14. After the rubber plug 18 is threadedly connected to the other end of the newly installed water pipe 25, the water pipe 25 and the atomizing nozzle 8 can be installed, thereby improving the dust suppression spraying range of the device.

[0030] The spring 9 is sleeved on the outer surface of the limiting rod 11, and a circle of sealing ring 12 is embedded in the bottom of the mounting block 7. Through the setting of the sealing ring 12 and the cooperation of the limiting rod 11 and the spring 9 and other structures, it can prevent clean water from flowing out from the connection between the mounting block 7 and the connecting piece to cause a waste of water resources.

[0031] The top of the water tank 2 is fixedly connected to two fixing frames 13, and the two fixing frames 13 are fixedly connected to the water pipe 1 4. The top of the vehicle body 1 is fixedly connected to two brackets 17, and the two brackets 17 are movably connected to the two water pipes 2 5 respectively.

[0032] The connecting assembly includes a threaded connection sleeve 14, which is arranged on the water pipe 1 4. The threaded connection sleeve 14 is threadedly connected to the water pipe 1 4 and one of the water pipes 2 5 respectively. The threaded connection sleeve 14 can move horizontally left and right on the water pipe 1 4 and the water pipe 2 5. Two sealing grooves 15 are provided inside the threaded connection sleeve 14. The two sealing grooves 15 are both provided with sealing rings 2 16. Through the setting of the two sealing rings 2 16, the connection between the two pipes can be sealed to prevent the transported water from flowing out of the connection between the two pipes.

[0033] Working principle: When working, first add a proper amount of clean water into the water storage tank 2, and then according to the dust suppression spraying range, the number of water pipes 25 and the number of atomizing nozzles 8 can be added, that is, rotate the rubber plug 18, separate it from one end of the corresponding water pipe 25, install a threaded connection sleeve 14 on the water pipe 25, take out a new water pipe 25 with a plurality of atomizing nozzles 8 installed on the top, and connect the water pipe 25 with the new water pipe 25 through the threaded connection sleeve 14, and thread the rubber plug 18 with the other end of the newly installed water pipe 25, then the installation of the water pipe 25 can be completed, and at the same time, the number of atomizing nozzles 8 and the dust suppression spraying range can be increased;

[0034] After the number of water pipes 2 5 is adjusted and installed, the water pump 3 is started to transport the clean water added in the water storage tank 2 to the inside of the water pipe 1 4, and after flowing into the inside of the water pipe 2 5 connected at both ends, it can be sprayed out from the atomizing nozzle 8 after passing through a number of connecting pipes 6 connected thereto, and dust reduction work can be performed on the dust generated at the construction site;

[0035] When some of the atomizing nozzles 8 on the water delivery pipe 1 4 or the water delivery pipe 2 5 are damaged due to the influence of dust during use and need to be replaced, the two shielding frames 10 at the damaged atomizing nozzle 8 can be manually pulled to move relative to each other, and the two limiting rods 11 can be driven to move relative to each other. After the two corresponding springs 9 are stretched, the two limiting rods 11 can be separated from the mounting block 7, and the limiting fixation of the corresponding mounting block 7 and the atomizing nozzle 8 can be released. The damaged atomizing nozzle 8 can be synchronously pulled out from the corresponding connecting pipe 6 together with the mounting block 7 for replacement;

[0036] When the dust suppression spray device is in use and a large number of atomizing nozzles 8 on one of the water pipes 5 are damaged and need to be replaced, the two threaded connection sleeves 14 on the water pipe 5 are rotated so that they are no longer threadedly connected to the water pipe 5, and the fixed limits on both ends of the water pipe 5 can be released. After pushing the two threaded connection sleeves 14 to move to the side away from the water pipe 5, the threaded connection sleeves 14 are prevented from hindering the disassembly and removal of the water pipe 5. The water pipe 5 and several damaged atomizing nozzles 8 thereon can be disassembled simultaneously, and a new water pipe 5 and several new atomizing nozzles 8 can be directly replaced, so as to avoid a large number of atomizing nozzles 8 being damaged and affecting the dust suppression spraying effect, and improve the replacement efficiency.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
