Description

Technical Field

[0001] This utility model belongs to the field of tunnel ventilation technology, and in particular relates to a ventilation device for highway tunnels. Background Technology

[0002] Ventilation systems for highway tunnels refer to a series of devices and systems used in highway tunnels to introduce fresh air, expel stale air, and regulate airflow. Their main purpose is to improve air quality within the tunnel, ensuring driving safety and the health of drivers and passengers.

[0003] Traditional tunnel ventilation systems typically use fans to draw in outside air and expel air from inside the tunnel, connecting it to the outside via ducts. However, once the ducts extend to the outside, the openings are usually covered with louvers. While this can block a significant amount of debris, smaller pieces of trash and leaves can still enter the ducts, affecting the fan's operation and potentially damaging it. Furthermore, the louver system requires multiple screws for installation, making it inconvenient and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation device for highway tunnels. By installing an intercepting net, specifically by inserting a rod into a connecting groove within a fixing block, the compression block, under the elastic action of a spring, adheres tightly to the inner wall of the connecting groove, thus fixing the rod inside the groove and securing the intercepting net. This method allows for quick installation via plug-in connection and easy disassembly by pulling the net, facilitating subsequent maintenance. The mesh-like design of the intercepting net ensures ventilation while effectively blocking external debris and leaves. This solves the problem of traditional tunnel ventilation devices using louvers to block openings, allowing smaller debris and leaves to still enter the duct, affecting fan operation and potentially damaging the fan.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0012] The insert rod is inserted into the fixing block for positioning and supporting the interception net.

[0013] Furthermore, the outer side of the extrusion block is provided with a protrusion, and the left and right sides of the extrusion block are provided with inclined surfaces. The outer side of the extrusion block contacts the inner wall of the docking groove through the protrusion. The protrusion on the outer side of the extrusion block can improve the fixing effect of the insertion rod, making the insertion rod less likely to loosen.

[0014] The protrusions on the outer side of the extrusion block are used to increase friction, and the inclined surfaces on the extrusion block are used to assist in pushing the extrusion block.

[0015] Furthermore, the extrusion block has slidably connected limit blocks on both the left and right sides inside. The side of the limit block away from the extrusion block is fixedly connected to the inner wall of the insertion rod. The limit block is used to restrict the extrusion block and limit its position to prevent it from detaching from the insertion rod.

[0016] Furthermore, the fall protection mechanism includes a support plate disposed at the bottom of the ventilation box. A base plate is installed at the center of the bottom of the ventilation box by screws. A socket is fixedly connected to the bottom of the base plate. The socket has an opening at the bottom. The top of the support plate is inserted into the opening at the bottom of the socket. Then, the bottom of the support plate is fixed to the ground by bolts. This method is convenient for installation. After the support plate is installed, there will be space between the top of the support plate and the opening.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model uses an interception net, specifically by inserting the net into the mating groove of the fixing block via a plug rod. The pressing block will then adhere tightly to the inner wall of the mating groove under the elastic action of a spring, thereby fixing the plug rod inside the mating groove and securing the net. This method allows for quick installation via plug-in connection and easy disassembly by pulling the net, facilitating subsequent maintenance. The net is mesh-like, ensuring ventilation while effectively intercepting external garbage and leaves.
