Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an environmentally friendly fan. Background Technology

[0002] Tunnels, especially highway tunnels, railway tunnels, and urban underground transportation hubs, are an important part of modern transportation networks. To ensure air circulation within tunnels, remove pollutants such as vehicle exhaust, and provide a safe and comfortable environment for drivers, passengers, and staff, tunnel ventilation systems are crucial. As the core equipment of the ventilation system, the performance of tunnel fans directly affects the operational safety and energy consumption level of the tunnel. Currently, traditional tunnel fans mostly use large axial flow fans. These fans typically have advantages such as simple structure, large air volume, and mature technology, and are widely used in long tunnel ventilation. They generate a strong axial airflow through impeller rotation to replace the air inside the tunnel. However, in practical applications, it has been found that existing tunnel fans still have many problems that urgently need to be solved.

[0003] When a fire occurs inside a tunnel, although axial flow fans can effectively remove smoke, the smoke contains a lot of heat and particulate matter. When these heat-containing particulate matter is discharged from the tunnel, it can affect the environment near the tunnel entrance. Axial flow fans are only responsible for discharging particulate matter from the tunnel, not removing it. In essence, this is a "transfer of pollutants" and does not fundamentally solve the particulate matter problem.

[0004] Therefore, those skilled in the art have provided an environmentally friendly fan to solve the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an environmentally friendly fan. Through the sleeve design of fixed and movable pipes, combined with multiple fixing holes and receiving bolts, the installation height of the entire fan can be flexibly adjusted to adapt to different tunnel heights and clearance requirements. This design allows the same model of fan to be applied to tunnels of various specifications, demonstrating strong versatility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An environmentally friendly fan includes a duct. Dust suppression components are provided on both the inner and outer walls of the duct. Each dust suppression component includes a water tank fixedly connected to the upper end of the outer wall of the duct. A water pump is fixedly connected to the front end of the upper surface of the water tank. A conveying ring is fixedly connected to the front end of the outer wall of the duct. Multiple conveying rectangular tubes are fixedly connected to the front end of the inner wall of the duct. Multiple atomizing nozzles are fixedly connected to the outer wall of each conveying rectangular tube on the side away from the inner wall of the duct. An installation assembly is provided at the upper end of the outer wall of the air duct. The installation assembly includes multiple fixed tubes that are fixedly connected to the front and rear parts of the upper end of the outer wall of the air duct. Each fixed tube has a movable tube at its upper end. The lower end of the movable tube body at the front and rear ends is slidably provided with receiving bolts. Each receiving bolt has a fixing bolt on one side. Multiple fixing holes are provided on both sides of the fixed tube body. An installation plate is fixedly connected to the upper surface of each movable tube. A motor bracket is fixedly connected to the rear end of the inner wall of the wind tunnel, a drive motor is fixedly connected to the inner wall of the motor bracket, and a blade is fixedly connected to the output end of the drive motor. The above technical solution allows the dust suppression components to effectively remove heat-containing particles from smoke during a fire, and the installation components allow the axial flow fan to be installed at the required height.

[0007] Furthermore, the output end of the water pump is connected to the conveying ring, and the input end of the water pump penetrates through the water storage tank to the inner bottom surface of the water storage tank; The above technical solution allows for the effective delivery of purified water via a specially designed water pump.

[0008] Furthermore, an inlet valve pipe is fixedly connected to the rear end of the upper surface of the water storage tank, and the inlet valve pipe is in communication with the water storage tank; The above technical solution allows for effective connection to the fire-fighting pipeline via the installed inlet valve pipe, thus replenishing the water supply to the water storage tank when necessary.

[0009] Furthermore, the conveying ring is connected to the conveying rectangular tube, and the conveying rectangular tube is connected to multiple atomizing nozzles; The above technical solution allows the pure water inside the water tank to flow more easily into the atomizing nozzle for atomization and spraying, thereby treating the heat-containing particulate matter in the gas blown by the blades.

[0010] Furthermore, one end of the receiving bolt passes through the fixing hole of the movable tube and the fixed tube, and the fixed tube and the movable tube are fixedly connected by the receiving bolt; The above technical solution allows for effective adjustment of the lengths of the movable and fixed pipes via the provided fixing holes, thus enabling the axial flow fan to be fixed at its height as needed.

[0011] Furthermore, the fixing bolt is threaded to the inner wall of the receiving bolt, and the lower end of the fixing bolt passes through the receiving bolt and is threaded to a fixing nut; The above technical solution effectively fixes the position of the receiving bolt by setting the fixing bolt, thus preventing it from separating from the body of the movable pipe and the fixed pipe. Then, the fixing nut can effectively fix the fixing bolt a second time, thereby improving the stability of the receiving bolt.

[0012] Furthermore, mounting holes are provided at all four corners of the mounting plate, and sturdy brackets are fixedly connected to the sides of the two movable tubes at the front and rear ends that are close to each other. The above technical solution allows for easier fixing of the mounting plate to the inner wall of the tunnel via multiple mounting holes, while the sturdy brackets effectively enhance the stability between the multiple movable pipes.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes an environmentally friendly fan. The dust suppression component atomizes water through atomizing nozzles and sprays it directly into the airflow inside the duct. This allows the water mist to fully contact, collide, and condense with dust and smoke particles in the airflow, increasing their weight and causing them to settle. This significantly reduces the concentration of particulate matter in the exhaust air. Instead of simply discharging pollutants from inside the tunnel to outside, this model purifies pollutants directly during the discharge process, reducing secondary pollution to the external environment of the tunnel entrance and effectively embodying the concept of "environmental protection".

[0014] 2. The environmentally friendly fan proposed in this utility model, through the sleeve design of fixed pipe and movable pipe, combined with multiple fixing holes and receiving bolts, can flexibly adjust the installation height of the entire fan, and can adapt to the height and clearance requirements of different tunnels. This design allows the same model of fan to be applied to tunnels of various specifications, with strong versatility. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. 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.

[0018] One specific embodiment of this utility model is provided: Reference Figure 1 , Figure 2 and Figure 5 An environmentally friendly fan includes a duct 1. Dust suppression components 2 are provided on both the inner and outer walls of the duct 1. The dust suppression components 2 include a water storage tank 201 fixedly connected to the upper end of the outer wall of the duct 1, a water pump 203 fixedly connected to the front end of the upper surface of the water storage tank 201, a conveying ring 206 fixedly connected to the front end of the outer wall of the duct 1, and multiple conveying rectangular tubes 205 fixedly connected to the front end of the inner wall of the duct 1. Multiple atomizing nozzles 204 are fixedly connected to the outer wall of the conveying rectangular tubes 205 on the side away from the inner wall of the duct 1. Reference Figure 2 , Figure 3 and Figure 4 : An installation assembly 3 is provided at the upper end of the outer wall of the air duct 1. The installation assembly 3 includes multiple fixed tubes 301 that are fixedly connected to the front and rear parts of the upper end of the outer wall of the air duct 1. Each fixed tube 301 has a movable tube 303 at its upper end. Each movable tube 303 has a receiving bolt 307 slidingly attached to the lower end of its body. Each receiving bolt 307 has a fixing bolt 305 on one side. Multiple fixing holes 302 are provided on both sides of the fixed tube 301. Each movable tube 303 has a mounting plate 304 fixedly attached to its upper surface. Reference Figure 3 : A motor bracket 6 is fixedly connected to the rear end of the inner wall of the air duct 1, a drive motor 5 is fixedly connected to the inner wall of the motor bracket 6, and a blade 4 is fixedly connected to the output end of the drive motor 5. The dust suppression component 2 can effectively remove heat-containing particles from smoke during a fire, and the installation component 3 can effectively install the axial flow fan at the required height.

[0019] Reference Figures 1-5 : The output end of the water pump 203 is connected to the conveying ring 206, and the input end of the water pump 203 passes through the water storage tank 201 to the inner bottom surface of the water storage tank 201. The water pump 203 effectively conveys purified water. An inlet valve pipe 202 is fixedly connected to the rear end of the upper surface of the water storage tank 201, and the inlet valve pipe 202 is connected to the water storage tank 201. The inlet valve pipe 202 effectively connects to the fire-fighting pipeline, thereby replenishing the water supply to the inside of the water storage tank 201 when necessary. The conveying ring 206... 06 is connected to the conveying rectangular tube 205, which is connected to multiple atomizing nozzles 204, so that the pure water inside the water storage tank 201 can flow more easily into the atomizing nozzles 204 for atomization and spraying, thereby treating the heat-containing particulate matter in the gas blown by the blade 4. One end of the receiving bolt 307 passes through the tube body of the movable tube 303 and the fixing hole 302 of the tube body of the fixed tube 301. The fixed tube 301 and the movable tube 303 are fixedly connected by the receiving bolt 307 through the provided fixing hole. 302 can effectively adjust the length of the movable pipe 303 and the fixed pipe 301, thereby fixing the height of the axial flow fan as needed. The fixing bolt 305 is threadedly connected to the inner wall of the receiving bolt 307. The lower end of the fixing bolt 305 passes through the receiving bolt 307 and is threadedly connected to the fixing nut 306. The fixing bolt 305 can effectively fix the position of the receiving bolt 307, thus preventing it from detaching from the pipe body of the movable pipe 303 and the fixed pipe 301. The fixing nut 306 can then effectively fix the fixing bolt 305 again, thereby improving the stability of the receiving bolt 307. The mounting plate 304 has mounting holes 309 at the four corners. The front and rear movable pipes 303 are fixedly connected to the side of each other. The mounting holes 309 can more easily fix the mounting plate 304 to the inner wall of the tunnel. The fixing brackets 308 can effectively improve the stability between the multiple movable pipes 303.

[0020] Working principle: During installation, the mounting plate 304 is fixed to the inner wall of the tunnel by bolts through the mounting holes 309. Then, the ventilation duct 1 is lifted by hoisting equipment. The fixed pipe 301 is then inserted into the movable pipe 303 from the bottom. As needed, any fixing hole 302 of the fixed pipe 301 is aligned with the hole in the body of the movable pipe 303. The receiving bolt 307 is then inserted into the movable pipe 303 and the fixing hole 302. The fixing bolt 305 is then screwed into the receiving bolt 307. The receiving bolt 307 is fixed by screwing the fixing nut 306 into the lower end of the fixing bolt 305, thereby fixing the position of the ventilation duct 1. Then, the fire water pipe is connected to the inlet valve pipe 202, and the power is turned on. In daily use, the drive motor 5 drives the blades 4 to rotate, thereby drawing in gas from the rear end of the ventilation duct 1 and discharging it from the front end. In the event of a fire in the tunnel and the need to exhaust smoke, the power of the drive motor 5 can be increased as needed, and the water pump 203 will draw pure water from the water storage tank 201 and deliver it to the inside of the conveying ring 206. The water is then diverted through the conveying ring 206 to the inside of the conveying rectangular tube 205, and then the water is atomized and sprayed out through the atomizing nozzle 204. This allows the water mist to fully contact, collide, and condense with the dust and smoke particles in the airflow, increasing their weight and causing them to settle, thereby significantly reducing the concentration of particulate matter in the exhaust air.
