Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices, in particular to a dust suppression device for construction projects. Background Art

[0002] Construction engineering refers to the general term for various buildings and engineering facilities that provide the material and technical basis for human life and production. Construction engineering is an organized, purposeful, large-scale economic activity of human beings. It not only includes construction engineering, civil engineering and electromechanical engineering, but also includes construction planning, survey and design, construction and installation, material and equipment procurement, project management and other links. Because there will be a lot of dust during construction on the construction site, if the dust is not purified in time, it will pollute the surrounding environment and affect the health of surrounding construction workers. Therefore, in the construction site, it is necessary to regularly carry out dust reduction treatment on the construction site, so dust reduction devices are needed. At present, the device commonly used for dust reduction on the construction site is a fog cannon.

[0003] The traditional fog cannon is mainly composed of a frame, a gun barrel and a water pump, among which a motor is installed at one end of the gun barrel, and the motor is used to drive the fan blades to rotate so that the sprayed atomized water has a longer range. However, since the fan needs to work continuously, when the fan fails unexpectedly, it needs to be repaired. At present, the protective net at the tail of the gun barrel is often removed to repair the motor. This process requires disassembling the screws one by one, which is cumbersome and time-consuming, resulting in low maintenance efficiency. In addition, due to the unique installation method of the fan and fan blades in the fog cannon, that is, the fan blades are closer to one end of the tail of the gun barrel, when the motor fails, the staff also need to disassemble the fan blades for better maintenance. In summary, when there is a problem with the motor in the traditional fog cannon, there is a disadvantage of being inconvenient for rapid maintenance. Therefore, a dust reduction device for construction engineering is proposed in view of the above situation. Utility Model Content

[0007] The limiting assembly includes a block, a groove, a slot body, a spring and a first rod body. The block is fixed to the outside of the gun barrel, and a groove is provided on one side of the block, a slot body is provided on one side of the groove, a spring is fixed to one end inside the slot body, and a first rod body is fixed to the other end of the spring. A second rod body is fixed to the middle position of one end of the first rod body inside the slot body, and a corresponding end of the second rod body passes through one side of the block and extends outside the block.

[0008] Preferably, the shift block is clamped in the groove, and the first rod body extends from one end located outside the groove body to the inside of the shift block.
