Background
In order to prevent rainwater from entering the interior along the air outlet of the equipment, rain-proof sheds are installed at the top ends of the air outlets in many enterprises. The weather enclosure is generally constructed by a steel structural frame and a weather shield. The steel framework is generally made into a trapezoidal structure and provided with supporting legs.
The existing rain-proof shed structure is in a form of welding a fixed rain-proof plate and a frame. When large-traffic exhaust, the weather shield can receive great exhaust pressure, and the strength counteracts the landing leg mounting panel that weather enclosure and aiutage are connected, causes the crater to tear, bolt fatigue fracture scheduling problem. Thereby leading to the weather enclosure eminence to fall, appearing the potential safety hazard, causing the incident even.
The existing rain-proof shed rain shield influences the smoothness of exhaust under the condition of large flow and large pressure of an exhaust port. In general design, the distance between the rain baffle and the bottom end of the air outlet is increased by lengthening the length of the supporting legs, and the acting force during large-flow high-pressure air exhaust is reduced by increasing the space of the air outlet. But this modification affects the rain protection capability of the rain shelter.
Finally, the structural form of the existing exhaust port rain-proof shed is low in safety performance, and the comprehensive performance of the existing exhaust port rain-proof shed in response to large-flow and large-pressure exhaust of the exhaust port is poor.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is that: in order to provide a better-effect rainproof shed with an automatic opening and closing type air outlet, a plurality of substantial technical effects of a specific implementation part are seen for a specific purpose.
In order to achieve the purpose, the utility model adopts the following technical proposal:
an automatic opening and closing type rain-proof shed of an exhaust port is characterized in that the middle of the rain-proof shed comprises a fixed rain-proof plate 1, the fixed rain-proof plate 1 is fixed on a roof, one side or two sides of the fixed rain-proof plate 1 are respectively hinged with an overturning rain-proof plate 4 through damping hinges 3, the lower part of the overturning rain-proof plate 4 is fixed, an anti-collision device 5 is fixed on a support leg 6, and the anti-collision device 5 is made of rubber; an air outlet is arranged below the rain shed.
The utility model discloses a further technical scheme lies in, fixed weather shield 1 fix on the roof through the stand.
The utility model discloses a further technical scheme lies in, 6 below of landing leg fix on the roof through bottom fixed knot constructs 7.
The utility model discloses a further technical scheme lies in, fixed weather shield (1) both sides extend outwards relatively, cover damping hinge (3).
The utility model discloses a further technical scheme lies in, fixed weather shield (1) below welding hinge welded plate (8), installation damping hinge (3) between hinge welded plate (8).
Adopt above technical scheme the utility model discloses, for prior art have following beneficial effect: this patent has designed an automatic formula weather enclosure structure that opens and shuts for the gas vent. In the structure, the overturning rain shield is connected with the fixed rain shield by a damping hinge in a movable hinge mode. When the equipment exhausts, the turnover rain baffle is influenced by the exhaust pressure and is opened upwards for a certain angle along the moving direction of the hinge joint. The rain baffle after being opened increases the exhaust angle and size, reduces the exhaust pressure of the rain-proof shed, and improves the safety and stability of the rain-proof shed.
As the flow rate and pressure of the exhaust port increase, the opening angle of the rain shield increases. After the exhaust stops, the rain shielding plate automatically closes downwards along the direction of the hinge movable joint under the action of the gravity of the rain shielding plate. The damping hinge can effectively control the running speed of the turnover rain shield in the opening and closing process, the anti-collision device can reduce the closing kinetic energy of the turnover rain shield for the second time, the rigid collision impact is effectively avoided, and the noise is reduced.

The patent provides a plurality of parallel schemes, and different expressions belong to an improved scheme based on a basic scheme or a parallel scheme. Each solution has its own unique features.
The first embodiment is as follows: combining fig. 1 with fig. 2 and fig. 3; an automatic opening and closing type rain-proof shed of an exhaust port is characterized in that the middle of the rain-proof shed comprises a fixed rain-proof plate 1, the fixed rain-proof plate 1 is fixed on a roof, one side or two sides of the fixed rain-proof plate 1 are respectively hinged with an overturning rain-proof plate 4 through damping hinges 3, the lower part of the overturning rain-proof plate 4 is fixed, an anti-collision device 5 is fixed on a support leg 6, and the anti-collision device 5 is made of rubber; an air outlet is arranged below the rain shed. The technical scheme of the invention has the following substantial technical effects and the realization process: the landing leg is welded with the exhaust port, and the double-layer steel plate at the bottom end of the landing leg is connected with a bolt and can be detached. The top of the frame is welded with the fixed rain shield. The fixed rain baffle is connected with the turnover rain baffle through a damping hinge. The contact position of the turnover rain baffle and the frame is provided with an anti-collision device. Install on the top of gas vent after the weather enclosure is whole to be assembled, play the effect that prevents the rainwater and get into the gas vent.
