Description

Technical Field

[0001] This utility model relates to the field of dust control technology in building construction, specifically a dust prevention device for housing expropriation and demolition projects. Background Technology

[0002] This dust spread prevention device is mainly used in housing expropriation and demolition projects to effectively prevent dust pollution caused by demolition work. Dust not only seriously affects air quality and increases the concentration of particulate matter such as PM2.5 and PM10, but may also pose a threat to the health and lives of surrounding residents. Therefore, the use of dust spread prevention devices is an essential environmental protection measure in demolition projects, and dust spread prevention devices are usually fog cannons.

[0003] However, existing fog cannons are usually used for dust suppression outdoors. When carrying out dust suppression tasks during demolition projects, the fog cannons need to move to different locations after suppressing dust in one area to cover different dust suppression areas. During this process, after the fog cannons complete the dust suppression task in one area, some water will adhere to the nozzles. In cold regions such as the north, this residual water will freeze quickly when it comes into contact with low-temperature air, thus affecting subsequent use. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, a dust suppression device for housing expropriation and demolition projects includes a control workbench 1, which supports the device and allows workers to operate it. An adjusting bracket 2 is mounted on top of the control workbench 1, and a fog cannon body 3 is mounted on top of the adjusting bracket 2. The fog cannon body 3 converts water into a mist for spraying. With the assistance of the adjusting bracket 2, the angle and direction of the fog cannon body 3 can be adjusted, thereby increasing the spraying area. A mounting shell 4 is movably connected to one end of the fog cannon body 3. A handle 5 is attached to the surface of the mounting shell 4, facilitating workers to pick up and store it. A heating pipe 6 is installed inside the mounting shell 4, heating the inside of the fog cannon body 3 and effectively reducing the risk of freezing and malfunction caused by cold weather in northern regions. Two mounting mechanisms 7 are located on one side of the mounting shell 4, centered on the fog cannon body 3. The axis is symmetrically designed. Under the action of the mounting mechanism 7, the mounting shell 4 can be limited, allowing the heating tube 6 to work at one end of the fog cannon body 3. A placement shell 8 is bolted to the surface of the control workbench 1. The placement shell 8 and the mounting shell 4 work together to facilitate the storage of the mounting shell 4 by the staff. A collection shell 9 is bolted to the bottom of the fog cannon body 3. The collection shell 9 can collect the water droplets generated when the fog cannon body 3 is working, reducing water waste. A [missing information - likely a device or mechanism] is bolted to the top of the control workbench 1. The fixed shell 10 has a transmission mechanism 11 on one side. Under the action of the transmission mechanism 11, the water droplets collected inside the collection shell 9 can be transmitted to the inside of the fixed shell 10. One side of the fixed shell 10 is connected to a conveying pipe 12. The other end of the conveying pipe 12 is connected to the water storage tank inside the control workbench 1. Under the action of the conveying pipe 12, the water source inside the fixed shell 10 can be transmitted to the water storage tank inside the control workbench 1, so that the water source can be sprayed out again through the fog cannon body 3, thereby making use of the water source.

[0022] The mounting mechanism 7 includes a movable block 71, one end of which is rotatably connected to the surface of the mounting shell 4. A limit rod 72 is slidably connected to the surface of the fog cannon body 3. A tension spring 73 is fixedly connected to one side of the limit rod 72, and the other end of the tension spring 73 is fixedly connected to the surface of the fog cannon body 3. Under the action of the mounting shell 4, the movable block 71 can rotate toward the surface of the fog cannon body 3. With the cooperation of the tension spring 73, the limit rod 72 can be inserted into the inner cavity of the movable block 71, thereby limiting the movable block 71. This allows the mounting shell 4 to drive the heating tube 6 to be installed at one end of the fog cannon body 3 for operation. This effectively reduces the possibility of the fog cannon body 3 freezing inside and failing to work due to the cold weather in the north, thus improving the practicality of the device.

[0023] The transmission mechanism 11 includes a connecting pipe 111. One end of the connecting pipe 111 is connected to one side of the collecting shell 9, and the other end of the connecting pipe 111 is connected to a flexible hose 112. The other end of the flexible hose 112 is connected to the top of the fixed shell 10. A filter screen 113 is installed inside the fixed shell 10. The conveying pipe 12 is located below the filter screen 113. Under the action of the connecting pipe 111, the water droplets collected inside the collecting shell 9 can be transmitted to the inner cavity of the fixed shell 10 through the flexible hose 112. With the cooperation of the filter screen 113, the water droplets can be filtered, thereby reducing water waste and improving water resource utilization. At the same time, the flexible hose 112 can adjust the angle and direction of the collecting shell 9 along with the fog cannon body 3.

[0024] Working principle: First, the operator moves the device to the corresponding working position. When the fog cannon body 3 cannot operate due to the cold weather in the north, the operator uses handle 5 to move the mounting shell 4 and the heating tube 6 out of the inner cavity of the placement shell 8. Then, the operator uses the limiting rod 72 to stretch the tension spring 73 on the surface of the fog cannon body 3, allowing the moving block 71 to rotate towards the surface of the fog cannon body 3. Then, under the action of the rebound force of the tension spring 73, the limiting rod 72 can move into the inner cavity of the moving block 71, so that the limiting rod 72 limits the mounting shell 4 through the moving block 71, allowing the heating tube 6 to heat the inside of the fog cannon body 3 from one end. When the fog cannon body 3 is ready to work, the operator puts the mounting shell 4 back into the inner cavity of the placement shell 8. The water droplets generated by the fog cannon body 3 during operation fall into the inside of the collection shell 9. With the help of the connecting pipe 111, the water droplets inside the collection shell 9 can be transferred to the inside of the fixed shell 10 through the hose 112. With the help of the filter screen 113, the water droplets can be filtered and the filtered water droplets can enter the water storage tank inside the control workbench 1 through the delivery pipe 12, so that the water source can be reused. With the help of the hose 112, the collection shell 9 can follow the adjusting bracket 2 to adjust the direction of the fog cannon body 3. After the dust prevention at the construction site is completed, the operator can turn off the device.
