Abstract
Description
Technical Field
[0001] This application relates to the technical field of ventilation systems, and particularly to a factory shed ventilation system. Background Art
[0002] In the environment of a storage factory shed, a ventilation system is usually required for ventilation to ensure the comfort of the storage environment and the working environment.
[0003] The related factory shed ventilation systems usually open exhaust vents at the top of the factory shed and install exhaust fans at the exhaust vents to achieve exhaust and heat dissipation of the internal environment of the factory shed. However, in rainy weather, rainwater easily flows into the factory shed from the exhaust vents, having an adverse impact on the storage environment. Utility Model Content
[0004] In order to reduce the adverse impact on the storage environment caused by rainwater flowing in from the exhaust vents, this application provides a factory shed ventilation system.
[0005] A factory shed ventilation system provided by this application adopts the following technical solutions:
[0006] A factory shed ventilation system includes a factory shed body. An exhaust vent is opened at the top of the factory shed body, and an exhaust fan is installed at the exhaust vent. A protective cover for shielding the exhaust vent is installed on the outer side of the factory shed body. A ventilation opening is provided on the protective cover, and the ventilation opening is opposite to the exhaust vent. A switching mechanism for opening and closing the ventilation opening is installed at the ventilation opening. The switching mechanism includes a switch board hinged at the ventilation opening and a driving component for driving the switch board to open and close.
[0007] By adopting the above technical solutions, when the protective cover shields the exhaust vent, rainwater infiltration can be reduced. The opening and closing of the ventilation opening are controlled by the switching mechanism. When it rains, the ventilation opening is closed to enable the protective cover to play a protective role. When it is sunny, the ventilation opening is opened for normal exhaust, thereby reducing the adverse impact on the storage environment caused by rainwater flowing in from the exhaust vents.
[0008] Optionally, the driving component is located on the side of the protective cover away from the exhaust vent. The driving component includes a motor fixed on the outer side of the exhaust hood. A rope winding roller is coaxially fixed to the output end of the motor. A connecting rope is wound around the rope winding roller. One end of the connecting rope away from the rope winding roller is fixedly connected to the upper side of the switch board.
[0009] By adopting the above technical solutions, the forward or reverse rotation of the rope winding roller is driven by the motor to realize the winding and unwinding of the connecting rope, thereby realizing the opening or closing of the switch board.
[0010] Optionally, a sealing ring is fixed to the side of the switch board close to the ventilation opening. When the switch board seals the ventilation opening, the sealing ring abuts against the inner wall of the ventilation opening.
[0011] By adopting the above technical solution, the sealing ring further enhances the sealing performance when the switch board seals the ventilation opening.
[0012] Optionally, an extension plate for shielding the motor is fixed to one side of the protective cover, and the extension plate is located above the motor.
[0013] By adopting the above technical solution, the extension plate blocks the motor located outside the protective plate, reducing the situation that the motor is wetted by rain during rainfall.
[0014] Optionally, a rain shield is fixed to the side of the extension plate away from the protective cover. The rain shield is parallel to the side wall of the protective cover, and there is a gap between the rain shield and the top of the factory shed body. The motor is fixed to the side of the rain shield close to the protective cover.
[0015] By adopting the above technical solution, the rain shield further improves the rain shielding effect on the motor.
[0016] Optionally, a through hole for the connecting rope to pass through is formed in the extension plate, and a fixed pulley is installed at the through hole. The connecting rope is slidably connected to the fixed pulley.
[0017] By adopting the above technical solution, the fixed pulley further reduces the friction force when the connecting rope is wound and unwound, ensuring the opening and closing of the switch board.
[0018] Optionally, the top of the protective cover has an inclined surface that gradually slopes downward from the side close to the extension plate to the side away from the extension plate.
[0019] By adopting the above technical solution, the inclined surface at the top of the protective cover further promotes the rainwater to slide away from the motor, and it is not easy to wet the motor.
[0020] Optionally, an air inlet is formed through the side of the protective cover close to the rain shield, and the air inlet is arranged opposite to the rain shield.
[0021] By adopting the above technical solution, the air inlet ensures that the exhaust fan can still perform the exhaust work on rainy days, and the rain shield helps to reduce the rainwater from entering through the air inlet.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When the protective cover shields the exhaust port, it can reduce the infiltration of rainwater. The opening and closing of the ventilation opening are controlled by the switch mechanism. When it rains, the ventilation opening is closed to make the protective cover play a protective role. When it is sunny, the ventilation opening is opened for normal exhaust;
[0024] 2. The sealing ring further enhances the sealing performance when the switch board seals the ventilation opening;
[0025] 3. The air inlet ensures that the exhaust fan can still carry out the exhaust work on rainy days, and the rain shield helps to reduce the entry of rainwater from the air inlet. Description of the Drawings

Detailed Implementation Modes
[0029] The following Figure 1-2 further describes the present application in detail.
[0030] The embodiment of the present application discloses a shed ventilation system.
[0031] Referring to Figure 1 , a shed ventilation system includes a shed body 1. An exhaust port 11 is opened through the top of the shed body 1, and an exhaust fan 12 is installed in the exhaust port 11. The exhaust fan 12 performs the exhaust work on the shed body 1 to ensure the comfort of the working environment in the shed body 1. A protective cover 2 is fixedly installed on the top of the shed body 1, and the protective cover 2 is fixedly installed on the upper side of the exhaust port 11. A ventilation opening 21 opposite to the exhaust port 11 is opened through the protective cover 2, and a switch mechanism 3 is installed at the ventilation opening 21. The switch mechanism 3 can realize the opening and closing at the ventilation opening 21, ensure the normal exhaust work of the exhaust fan 12 on sunny days, and close the ventilation opening 21 during rainfall to protect the exhaust port 11 and reduce the adverse impact on the storage environment caused by the inflow of rainwater from the exhaust port 11.
[0032] The top of the protective cover 2 has an inclined surface arranged obliquely, so that the rainwater falling on the protective cover 2 can automatically fall obliquely along the inclined surface. An extension plate 22 is fixed on one side of the protective cover 2. The extension plate 22 is located on the side with a higher position of the protective cover 2, so that the inclined surface at the top of the protective cover 2 is gradually inclined downward from the side close to the extension plate 22 to the side away from the extension plate 22. A vertically arranged rain shield 23 is also fixed on the side of the extension plate 22 away from the protective cover 2, and there is a gap between the rain shield 23 and the shed body 1.
[0033] Referring to Figure 2, the switch mechanism 3 includes a switch board 31 hinged to the protective cover 2. One side of the switch board 31 is hinged at the ventilation opening 21, enabling it to rotate in the vertical direction, and the switch board 31 can block the ventilation opening 21. A sealing ring 311 is also fixed on the switch board 31. When the switch board 31 blocks the ventilation opening 21, the sealing ring 311 abuts against the ventilation opening 21, further enhancing the sealing performance when the switch board 31 is closed and reducing rainwater infiltration.
[0034] The switch mechanism 3 further includes a driving component 32 for driving the rotation of the switch board 31. The driving component 32 realizes the opening and closing at the ventilation opening 21 to meet the usage requirements under different weather conditions. The driving component 32 includes a motor 321, and the motor 321 is fixed on the side of the rain shield 23 close to the protective cover 2, so that the extension plate 22 and the rain shield 23 play a protective role for the motor 321.
[0035] The output end of the motor 321 is fixed with a rope winding roller 322. The axis of the rope winding roller 322 is horizontally arranged. A connecting rope 323 is wound around the rope winding roller 322. A through hole 221 is opened on the extension plate 22, and a fixed pulley 222 is installed at the through hole 221. The axis of the fixed pulley 222 is parallel to the axis of the rope winding roller 322. The connecting rope 323 passes through the through hole 221 and extends out of the extension plate 22, and the connecting rope 323 abuts against the fixed pulley 222 to reduce the friction when the connecting rope 323 slides. The end of the connecting rope 323 away from the rope winding roller 322 is fixedly connected to the side of the switch board 31 away from the extension plate 22. The motor 321 drives the rotation of the rope winding roller 322 to realize the winding and unwinding of the connecting rope 323, so that the connecting rope 323 can pull the switch board 31 to rotate and open or close.
[0036] An air inlet 24 is also penetrated and opened on the side wall of the protective cover 2 close to the rain shield 23. The air inlet 24 is opposite to the position of the rain shield 23, and the air inlet 24 is communicated with the exhaust port 11. When it rains, the rain shield 23 can block the air inlet 24 to ensure the normal operation of the exhaust fan 12.
[0037] The implementation principle of a factory shed ventilation system in an embodiment of the present application is as follows:
[0038] When it rains, the protective cover 2 blocks the air inlet 24 to reduce rainwater from entering the factory shed body 1 through the exhaust port 11. The exhaust port 11 is communicated with the outside through the air inlet 24 to ensure the normal operation of the exhaust fan 12. When it is sunny, the driving component 32 drives the switch board 31 to rotate and open, further ensuring the exhaust effect of the exhaust fan 12. The inclined surface on the upper side of the protective cover 2 facilitates the rainwater to slide downwards. The extension plate 22 and the rain shield 23 play a shielding role for the motor 321, reducing the situation where the motor 321 is wetted.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
