Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a dust suppression device for civil engineering. Background Technology

[0002] In civil engineering construction, mist spraying equipment is often installed at construction sites to reduce dust and lower temperatures. This equipment uses a high-pressure pump to pressurize water to over 40 kg, atomizing it into tiny droplets through high-pressure nozzles. These droplets can float in the air for extended periods, possessing strong surface activity and adsorption capacity, effectively adsorbing suspended dust particles while also providing a cooling effect, preventing the construction site from becoming too dry and mitigating fire hazards. However, since the spraying structure of mist spraying equipment is usually fixed to the construction site, and the nozzles are typically located at high altitudes, and these nozzles are prone to clogging after prolonged use, workers must remove and clean them from a height. This disassembly before cleaning the nozzles poses a safety hazard. Therefore, this paper proposes an environmentally friendly dust suppression device for civil engineering projects to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dust suppression environmental protection device for civil engineering includes a mist spraying system. The mist spraying system has a fixed base at the bottom outer side of the spraying structure. A fixed cover is fixedly connected to the rear end of the fixed base. A positioning shaft is rotatably connected to the inner side of the fixed cover. A roller is fixedly connected to one end of the positioning shaft. A pull rope is fixedly connected to the outer side of the roller, passing through the fixed cover and the fixed base. The pull rope is slidably connected to the fixed cover and the fixed base. The other end of the pull rope is fixedly connected to the spraying structure of the mist spraying system.

[0005] As a further improvement of this utility model, a fixed shaft is rotatably connected to the top inner side of the fixed base, and the fixed shaft is fixedly connected to the spraying structure of the fog pile spraying equipment. A spring is fixedly connected to the outer side of the fixed shaft, and the other end of the spring is fixedly connected to the fixed base.

[0006] As a further improvement of this utility model, one end of the outer side of the pull rope contacts a guide wheel, and the guide wheel is rotatably connected to the fixed base through a rotating shaft.

[0007] As a further improvement of this utility model, a worm gear is fixedly connected to the other end of the outer side of the positioning shaft, and a worm that penetrates the fixed cover is meshed with the outer side of the worm gear, and the worm is rotatably connected to the fixed cover.

[0008] As a further improvement of this utility model, the metal water pipe at the bottom of the spray structure of the mist pile spraying device is in contact with a fixed pipe that is in contact with a fixed seat. The front end of the fixed pipe is connected to a connecting pipe that penetrates the fixed seat and is in contact with the fixed seat. The other end of the connecting pipe is connected to the pump body structure of the mist pile spraying device. The rear end of the fixed pipe is fixedly connected to a pedal that penetrates the fixed seat and is slidably connected to the fixed seat. The bottom end of the fixed pipe is fixedly connected to a spring, and the other end of the spring is fixedly connected to the fixed seat. The top end of the fixed pipe is fixedly connected to a rubber sealing ring, and the sealing ring is in close contact with the spray structure of the mist pile spraying device.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The dust suppression device for civil engineering projects, consisting of a mist spray system, worm gear, worm wheel, reel, pull rope, spring, and fixed shaft, operates during dust suppression in civil engineering construction. When the nozzles at the top of the mist spray system become clogged, the connection of the spray system is disconnected, and the worm gear is rotated to engage the worm wheel. This, in turn, drives the reel to rotate via the positioning shaft. The spring force on the fixed shaft causes the spray system to continuously pull the pull rope as it rotates, pulling it out from the outside of the reel. When the top nozzle is rotated to a lower position, it can be removed for cleaning. By controlling the rotation of the spray system at a lower position, the top nozzle is easily removed for cleaning, ensuring worker safety.

[0010] 2. The environmental dust suppression device for civil engineering uses a pedal, a fixed pipe, and a spring. When the nozzles of the mist spraying equipment become clogged, stepping on the pedal further compresses the spring in the fixed pipe. This prevents the rubber sealing ring from contacting the spraying structure of the mist spraying equipment, facilitating the disconnection between the spraying structure and the pump body. This also makes it easier to control the spraying structure to rotate the top nozzles to a lower position for disassembly and cleaning. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 like Figure 1-5 As shown, the environmental dust suppression device for civil engineering includes a fog spraying device 1. The bottom of the outer side of the spraying structure of the fog spraying device 1 is provided with a fixed base 2. The rear end of the fixed base 2 is fixedly connected to a fixed cover 5. The inner side of the fixed cover 5 is rotatably connected to a positioning shaft 6. One end of the positioning shaft 6 is fixedly connected to a roller 7. The outer side of the roller 7 is fixedly connected to a pull rope 8 that passes through the fixed cover 5 and the fixed base 2. The pull rope 8 is slidably connected to the fixed cover 5 and the fixed base 2. The other end of the pull rope 8 is fixedly connected to the spraying structure of the fog spraying device 1.

[0020] Example 2 like Figure 1-2As shown, in order to solve the problem that it is inconvenient to autonomously control the spray structure of the fog pile spraying device 1 to rotate in a designated direction after the control rope 8 rotates out from the outside of the reel 7, a fixed shaft 3 is rotatably connected to the top of the inner side of the fixed base 2, and the fixed shaft 3 is fixedly connected to the spray structure of the fog pile spraying device 1. A spring 4 is fixedly connected to the outside of the fixed shaft 3, and the other end of the spring 4 is fixedly connected to the fixed base 2. After the control rope 8 rotates out from the outside of the reel 7, the fixed shaft 3 drives the spray structure of the fog pile spraying device 1 to rotate under the elastic force of the spring 4, which facilitates the autonomous control of the spray structure of the fog pile spraying device 1 to rotate in a designated direction.

[0021] Example 3 like Figure 3-4 As shown, in order to solve the problem that the pull rope 8 will generate a lot of friction between the pull rope 8 and the fixed base 2 and the fixed cover 5 when the spray structure of the fog pile sprinkler equipment 1 is pulled, a guide wheel 9 is contacted at one end of the outer side of the pull rope 8, and the guide wheel 9 is rotatably connected to the fixed base 2 through a rotating shaft. When the spray structure of the fog pile sprinkler equipment 1 pulls the pull rope 8, the guide wheel 9 guides the pull rope 8, thus avoiding the large friction between the pull rope 8 and the fixed base 2 and the fixed cover 5.

[0022] Example 4 like Figure 3 and Figure 5 As shown, in order to solve the problem of inconvenience in controlling the pull rope 8 to rotate out from the outside of the reel 7, a worm gear 10 is fixedly connected to the other end of the outer side of the positioning shaft 6. A worm 11 that penetrates the fixed cover 5 is meshed with the outer side of the worm gear 10, and the worm 11 is rotatably connected to the fixed cover 5. By rotating the worm 11 to mesh with the worm gear 10, it is convenient to control the pull rope 8 to rotate out from the outside of the reel 7.

[0023] Example 5 like Figure 1-3As shown, to address the issue of inconvenience in disconnecting the spray structure of the mist spraying device 1, a fixed pipe 12 is attached to the outside of the metal water pipe at the bottom of the spray structure of the mist spraying device 1, which contacts the fixed base 2. The front end of the fixed pipe 12 is connected to a connecting pipe 13 that penetrates the fixed base 2, and the connecting pipe 13 contacts the fixed base 2. The other end of the connecting pipe 13 is connected to the pump body structure of the mist spraying device 1. A pedal 14 that penetrates the fixed base 2 is fixedly connected to the rear end of the fixed pipe 12, and the pedal 14 slides against the fixed base 2. The fixed tube 12 is connected to a spring 15 at its bottom end, and the other end of the spring 15 is fixedly connected to the fixed base 2. The fixed tube 12 is connected to a rubber sealing ring 16 at its top end, and the sealing ring 16 is in close contact with the spray structure of the fog pile spraying equipment 1. By stepping on the pedal 14, the fixed tube 12 is further compressed to compress the spring 15, so that the fixed tube 12 drives the rubber sealing ring 16 to not contact the spray structure of the fog pile spraying equipment 1, which facilitates the disconnection of the spray structure of the fog pile spraying equipment 1.

[0024] In this embodiment, during the dust suppression operation of the device during civil engineering construction, when the nozzle at the top of the spray structure of the fog pile sprinkler equipment 1 becomes clogged, the foot pedal 14 is first pressed to compress the spring 15 of the fixed pipe 12 connected to the connecting pipe 13 on the outside. This prevents the rubber sealing ring 16 of the fixed pipe 12 from contacting the spray structure of the fog pile sprinkler equipment 1. At this time, the connection between the spray structure of the fog pile sprinkler equipment 1 and the pump body structure of the fog pile sprinkler equipment 1 can be released. After the connection of the spray structure of the fog pile sprinkler equipment 1 is released, the worm gear 11 is rotated to engage the worm wheel 10, which in turn drives the winding wheel 7 to rotate through the positioning shaft 6. At this time, under the elastic force of the spring 4 on the fixed shaft 3, the spray structure of the fog pile sprinkler equipment 1, supported by the fixed seat 2, will continuously pull the pull rope 8 during the rotation, thereby continuously pulling the pull rope 8 out from the outside of the winding wheel 7. When the top nozzle of the fog pile sprinkler equipment 1 rotates to a lower position, it can be removed for cleaning.
