Description

Technical Field

[0001] This utility model relates to the field of highway traffic safety equipment technology, and in particular to the structure of the smoke blowing part of a flexible barrier device. Background Technology

[0002] The smoke exhaust section of a flexible barrier device is a barrier system installed on a traffic road to prevent vehicles behind from continuing to travel and thus avoid secondary traffic accidents.

[0003] In the prior art, patent application number (202510131696.X) discloses a smoke blowing part structure of a flexible barrier device. In this patent structure, a fan is installed inside the box, and a smoke guide hood and an air inlet hood are respectively connected to the air outlet and air inlet end of the fan. Cylindrical smoke storage tanks with sealed outer ends are evenly arranged on the inner circumferential surface of the air inlet hood. The smoke storage tank is used to store saturated fatty acid-lipid distributed combustion smoke. The side of the box opposite to the outer end of the air inlet hood is open and has a fan door. The fan door has an opening for air intake.

[0004] However, the above-mentioned patented structure has the following disadvantages when in use: 1. Since the equipment is installed outdoors, the saturated fatty acid-ester distributed combustion smoke stored in the smoke tank inside the air inlet hood is easily wetted by rainwater, affecting its effectiveness; 2. The smoke guide hood design is not reasonable enough, it cannot form a smoke wall to complete flexible blocking, and the structural design is complicated and inconvenient to process and manufacture; 3. It is inconvenient to replace the smoke tank.

[0005] Therefore, how to design a flexible barrier device with a simpler and more reasonable structure, better rainproof effect, better flexible barrier function, and easier smoke tank replacement has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a flexible barrier device with a simpler and more reasonable structure, better rainproof effect, better flexible barrier function, and more convenient smoke tank replacement for the smoke blowing part structure.

[0007] To achieve the above objectives, this utility model provides a smoke exhaust section structure for a flexible barrier device, including a smoke guide hood installed inside a housing, and a fan installed at the rear end of the smoke guide hood; an opening is provided on the side of the housing opposite to the fan inlet, and a fan door is hinged thereon; the key feature is that an air inlet hood is installed on the inner side of the fan door, and an air inlet is provided on the fan door corresponding to the air inlet hood; the air inlet hood includes an outer support shell, and two or more air guide tubes are arranged vertically at intervals inside the support shell at the end adjacent to the fan door, and multiple partitions are provided between the outer walls of two adjacent air guide tubes, forming a placement space with an open front end between the partitions, in which a smoke storage tank can be arranged and fatty acid-ester distributed combustion smoke can be stored; a semi-circular protective plate is provided at the front end of the air guide tube, and the upper end of the protective plate is bent forward horizontally to form a bent section; and a connecting port is provided at the front end of the support shell, so that after the fan door is closed, the connecting port of the support shell can be connected to the fan inlet.

[0008] Thus, in the smoke exhaust section of the aforementioned flexible barrier device, a semi-circular protective plate is installed at the front end of the air guide duct, with the upper end of the plate bent horizontally forward to form a bend. This effectively blocks rainwater brought in by the working airflow, preventing it from affecting the distributed combustion smoke of fatty acids-esters stored in the smoke tank. Secondly, by installing the air inlet hood on the fan door, the hood rotates with the fan door when it is opened, making it easier to replace the smoke tank within the storage space. This results in a structure with better rain protection and facilitates easier replacement of the smoke tank.

[0009] As an optimization, three air guide tubes are vertically spaced inside the support shell, and a connection port is provided at the front end of the support shell, each facing the air guide tube; and three fans are arranged, each corresponding to the connection port.

[0010] In this way, the number of air ducts is set more reasonably, which in turn makes the placement of the space between the partitions more reasonable.

[0011] As an optimization, the smoke guide hood includes a guide shell with an overall rectangular box structure and an open front end. At the rear end of the guide shell, there is a corresponding interface for each fan, and the air outlet of the fan is connected to the corresponding interface. Inside the guide shell, there is a guide grille, which includes two horizontal guide grille plates, each of which is arranged between two adjacent fans.

[0012] In this way, the structural design of the smoke deflector is simpler and more reasonable, making it easier to process and manufacture. The smoke flowing out through the grille is better, forming a smoke wall more effectively, thus improving the flexible barrier effect.

[0013] As an optimization, a fixed flange is provided at the front end of the fan, and the fixed flange is attached to the rear side of the guide shell.

[0014] This makes it easier to install and fix the fan and the guide shell, and the structural design is simpler.

[0015] As an optimization, the rear end of the support shell is provided with an installation flange and is installed on the fan door.

[0016] This makes the installation between the support shell and the fan door simpler and also improves the stability of the installation.

[0017] As an optimization, a ring-shaped sealing flange is provided at the rear end of the fan, and a sealing ring is provided on the sealing flange. After the fan door is closed, the sealing ring can be attached to and supported on the front side of the support shell to form a seal.

[0018] In this way, by setting a sealing flange at the rear end of the fan, a sealing ring can be installed on the sealing flange, so that the fan and the front side of the support shell can be sealed, thus better preventing smoke from being scattered and wasted.

[0019] As an optimization, a mounting plate is provided on the enclosure, and a directional broadcaster, an anemometer, and two cameras are installed on the mounting plate.

[0020] This makes the installation of the directional broadcaster, anemometer, and two cameras more reasonable and easier to maintain.

[0021] In summary, the above structure features a protective plate at the front end of the air duct, which is bent into sections to provide better rain protection. The design of the smoke guide hood further enhances the smoke wall effect and improves the flexible barrier effect. Finally, placing the air inlet hood on the fan door makes it easier to replace the smoke storage tank. Attached Figure Description

[0038] In this specific embodiment, a fixed flange 16 is provided at the front end of the fan, and the fixed flange is attached to the rear side of the guide shell.

[0039] This makes it easier to install and fix the fan and the guide shell, and the structural design is simpler.

[0040] In this specific embodiment, the rear end of the support shell is provided with an installation flange 17 and is installed on the fan door.

[0041] This makes the installation between the support shell and the fan door simpler and also improves the stability of the installation.

[0042] In this specific embodiment, a ring-shaped sealing flange 18 is provided at the rear end of the fan, and a sealing ring is provided on the sealing flange.
