Description

Technical Field

[0001] This utility model relates to the field of tunnel equipment technology, and in particular to a novel tunnel ventilation fan. Background Technology

[0002] Tunnel ventilation fans ensure air circulation within tunnels. In tunnels, vehicle exhaust and airborne pollutants gradually accumulate, severely impacting air quality. Ventilation fans continuously introduce fresh air into the tunnel while expelling exhaust fumes and pollutants, thus maintaining fresh and clean air. Especially in emergencies such as fires, fans can quickly remove smoke and harmful gases, ensuring visibility within the tunnel and providing crucial support for escape and rescue efforts.

[0003] In existing technology, tunnel ventilation fans consist of several sets of motors and fan blades. The motors are mounted on the back using conventional cross-shaped brackets. The cross-shaped brackets occupy a certain amount of space, causing eddies or reduced airflow velocity when the air passes through, thus reducing the overall ventilation volume. Since tunnel ventilation fans have several sets of brackets and fans installed inside, their ventilation volume is insufficient, so optimization and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a novel tunnel ventilation fan to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a novel tunnel ventilation fan, comprising a fan consisting of several air sections connected end to end; The outer surface of the wind joint is fixedly connected to an outer edge, and a number of positioning holes are provided on the outer edge. A connecting mechanism is installed at the positioning holes between the outer edges that are in contact with each other. The bottom of the inner side of the wind joint is fixedly connected to a first support plate, and the top of the first support plate is fixedly connected to a connecting plate. The top of the connecting plate is fixedly connected to a second support plate, and the two ends of the second support plate are fixedly connected to the inner side of the wind joint. The wind-receiving surfaces of the first and second support plates are designed as streamlined surfaces, and the transition between the second and first support plates is smoothed. The bottom of the second support piece is fixedly connected to a filler plate, which is located between the connecting plates and fills the gap between the connecting plates. A motor is mounted on the top of the second support plate. The output end of the motor is fixedly connected to a connector, and the output end of the connector is fixedly connected to several fan blades.

[0007] Preferably, from any of the above embodiments, the fan is in the shape of a long cylindrical tube.

[0008] The above technical solution is adopted: This device is specially designed for use in tunnels. The device is hoisted on the top of the tunnel. The fan is composed of several air sections connected end to end. The outer edges of the air sections are close to each other and the positioning holes are aligned. The internal support structure is aligned and then connected by a connecting mechanism. The air outlet of the fan faces the tunnel entrance. When the motor starts, the numerous fan blades rotate at high speed. It ensures air circulation within the tunnel. In tunnels, vehicle exhaust and airborne pollutants gradually accumulate, severely impacting air quality. The ventilation system continuously introduces fresh air into the tunnel while expelling exhaust fumes and pollutants, thus maintaining fresh and clean air. Especially in emergencies such as fires, the ventilation system can quickly remove smoke and harmful gases, ensuring visibility within the tunnel and providing strong support for escape and rescue.

[0009] Preferably, in any of the above schemes, the air joints are connected by an outer edge, positioning holes, and a connecting mechanism, wherein the positioning holes are arranged in a circumferential array around the axis of the air joint.

[0010] Preferably, in any of the above solutions, the connecting mechanism is a bolt and nut assembly, wherein the bolt is inserted into a positioning hole and the end of the bolt is threaded with a nut.

[0011] Preferably, the inner sides of the first and second support plates are welded together, and both the first and second support plates are thin stainless steel sheets with flat surfaces.

[0012] The core structure of this device, employing the above technical solution, consists of a first support plate, a connecting plate, a second support plate, a streamlined surface, and a filling plate. The core advantages of this device are: the motor inside the fan abandons the use of a star-shaped bracket for installation, instead adopting a novel bracket design composed of a first support plate, a connecting plate, a second support plate, and a filling plate. The first and second support plates are both flat, thin stainless steel plates with a small air-receiving area. The air-receiving surfaces of the first and second support plates are designed as streamlined surfaces, and the transition between the second and first support plates is smoothed, allowing air to flow more smoothly over the bracket and reducing eddies caused by abrupt changes in shape. The streamlined design effectively reduces wind resistance and improves ventilation efficiency. The design of the filling plate fills the gaps between the plates, which reduces air collision and separation on the support, thereby reducing eddies and backflow. The fan using this new design can maximize ventilation volume, reduce wind resistance, and improve ventilation efficiency.

[0013] Preferably, in any of the above solutions, the angle between the first support plate and the connecting plate is an obtuse angle, and the top surface of the connecting plate is welded to the bottom surface of the first support plate.

[0014] Preferably, in any of the above embodiments, the filler plate is made of stainless steel and is welded to the bottom surface of the connecting plate.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This new type of tunnel ventilation fan utilizes a combination of a first support plate, a connecting plate, a second support plate, streamlined surfaces, and a filling plate. Instead of using a traditional X-shaped bracket for motor installation, it employs a novel bracket design consisting of a first support plate, a connecting plate, a second support plate, and a filling plate. The first and second support plates are flat, thin stainless steel plates with a small air-receiving area. The air-receiving surfaces of the first and second support plates are designed with streamlined surfaces, and the transition between the second and first support plates is smoothed. This allows for smoother airflow through the bracket, reducing eddies caused by abrupt changes in shape. The streamlined design effectively reduces wind resistance and improves ventilation efficiency. The design of the filling plate fills the gaps between the plates, which reduces air collision and separation on the support, thereby reducing eddies and backflow. The fan using this new design can maximize ventilation volume, reduce wind resistance, and improve ventilation efficiency.
