Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, specifically relating to a guide deceleration device for ventilation. Background Technology

[0002] With the rapid development of my country's economy and the acceleration of urbanization, highway construction has become a crucial technological infrastructure supporting the country's economic and social development. In recent years, my country's highway construction has achieved remarkable success, with the highway network continuously expanding in scale and improving in quality. As road construction technology requirements continue to rise, the level of mechanized road construction operations has also significantly improved, and the variety of specialized road construction vehicles continues to increase.

[0003] During road construction operations, the engine cooling fan of a special-purpose vehicle continuously runs, generating a strong airflow that blows onto the road surface, seriously affecting the quality of road construction and causing dust pollution, which in turn impacts the air quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reasonably designed and simple structured guide deceleration device for exhaust.

[0005] The technical solution adopted to solve the above technical problems is: a guide deceleration device for exhaust, wherein a side fixing plate is provided on one side of the base plate, the included angle between the side fixing plate and the upper surface of the base plate is an obtuse angle, and a uniformly distributed guide plate is provided in the middle of the upper surface of the base plate. The guide plate is a right-angled trapezoidal plate, the hypotenuse side of the guide plate is connected to the mounting plate, the small end of the guide plate is for air intake and the large end is for air exhaust, and there is a certain distance between the small end of the guide plate and the side fixing plate.

[0006] Preferably, mounting plates are provided on both sides of the guide plate on the base plate.

[0007] Preferably, the angle between the mounting plate and the base plate is an acute angle, so that the air output by the guide plate is in a horizontal direction.

[0008] Preferably, the number of the guide vanes is 4 to 8.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention can change the direction of wind blowing vertically towards the road surface to a horizontal direction, while reducing wind speed. This protects the quality of the road surface during construction work and reduces secondary dust, thus minimizing the impact of wind on construction operations. Construction workers can work in a more suitable environment, which is both environmentally friendly and improves construction efficiency. This invention has a simple structure, is easy to manufacture and install, and can be widely used. Attached Figure Description

[0013] The components include: base plate 1, guide plate 2, side fixing plate 3, and mounting plate 4. Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0015] exist Figure 1 , 2 In this embodiment, a guide deceleration device for exhaust is provided. A side fixing plate 3 is fixedly installed on one side of the base plate 1. The angle β between the side fixing plate 3 and the upper surface of the base plate 1 is an obtuse angle. The side fixing plate 3 is used to fix the present invention on the road construction special operation vehicle and to block the wind. When the present invention is installed on the road construction special operation vehicle through the side fixing plate 3, the base plate 1 is tilted downward. The upper surface of the base plate 1 is provided with uniformly distributed guide plates 2. The number of guide plates 2 can be 6, 4 or 8. The guide plates 2 are right-angled trapezoidal plates. The inclined side of the guide plate 2 is connected to the mounting plate 4 with the small end facing upward and the large end facing downward. This makes the air duct formed by two adjacent guide plates 2 smaller at the end closer to the base plate 1 and larger at the end farther away from the base plate 1. The small end of the guide plate 2 and the side fixing plate 3 are spaced at a certain distance to form an air flow deflection zone. The vertical airflow is converted to the horizontal direction after passing through the deflection zone and enters from the small end of the air duct and flows out from the large end.

[0016] In this embodiment, mounting plates 4 are provided on both sides of the guide plate 2 on the base plate 1. The included angle α between the mounting plate 4 and the base plate 1 is an acute angle, so that the air output by the guide plate 2 is in a horizontal direction. The mounting plates 4 facilitate the docking and installation of this utility model with different special-purpose vehicles.

[0017] In use, this utility model is installed on the air outlet of the engine cooling fan. The air blown out by the engine cooling fan first reaches the airflow deflection zone of this utility model. The deflection zone buffers and changes the direction of the airflow. Then, it is blown out horizontally through the guide plate 2. Due to the air duct formed by the guide plate 2, the air inlet is small and the air outlet is large, which has a secondary deceleration effect on the airflow. This changes the strong wind blowing vertically towards the road surface into a relatively weak wind in the horizontal direction. While protecting the quality of the road surface during construction, it also reduces secondary dust on the road surface and protects the environment.
