Description

Technical Field

[0001] This utility model relates to the technical field of roof ventilation devices, and in particular to a roof ventilation device that is easy to install. Background Technology

[0002] Roof ventilators, also known as roof natural ventilators or roof surface natural ventilators, are mainly based on the aerodynamic wind load theory that "when wind acts on an object, the windward side experiences pressure, while the leeward side and the side facing the wind experience suction." Roof ventilators can be classified according to their shape and structure into: curved roof ventilators and spherical roof ventilators. In some factories that generate a lot of heat, exhaust fans are often installed at the exhaust vents to increase airflow circulation speed. The exhaust fans work in conjunction with the roof ventilators to meet the required airflow circulation speed. However, increasing airflow circulation speed by installing exhaust fans increases the factory's electricity consumption, which contradicts the advocated energy conservation and emission reduction principles.

[0003] A search revealed Chinese Patent Publication (Announcement) No. CN114961072, which discloses an arc-shaped roof ventilator. This patent, through the arrangement of exhaust fan blades and a horizontal rotating shaft, can reduce the power consumption of the factory, which is more in line with the energy conservation and emission reduction concept advocated by people. However, the installation of existing ventilators is usually quite cumbersome. The installer needs to install various accessories to facilitate the fixing of the ventilator, and it is not easy to disassemble it quickly after fixing. In addition, the above-mentioned patent uses a rain shield. When the air rises in the factory, the ventilation efficiency may be low due to the obstruction of the rain shield. Therefore, it is necessary to design a roof ventilation device that is easy to install. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, an easy-to-install roof ventilation device includes a trapezoidal frame 1 and a base 2. The upper surface of the base 2 is fixedly connected to the main body 3, and the lower surface of the base 2 is provided with a trapezoidal groove 4. The trapezoidal frame 1 and the trapezoidal groove 4 are slidably connected.

[0023] In this embodiment, a first screw 5 is threadedly connected to the upper surface of the trapezoidal frame 1. One end of the first screw 5 penetrates the upper surface of the trapezoidal frame 1 and extends to the lower surface of the trapezoidal frame 1. A stop 6 is provided on both the front and back sides of the trapezoidal frame 1. A second screw 7 is threadedly connected to the outer surface of the stop 6. The second screw 7 penetrates the outer surface of the stop 6 and is threadedly connected to the trapezoidal frame 1.

[0024] In practical use, the trapezoidal frame 1 is placed on the roof where it needs to be installed. The first screw 5 is used to connect and fix the trapezoidal frame 1 to the roof. Then, the base 2 and the trapezoidal frame 1 are installed by sliding the trapezoidal groove 4 of the base 2 with the trapezoidal frame 1. Finally, the second screw 7 is used to install the baffle 6 to limit the position of the base 2 and prevent the base 2 from moving. This facilitates the installation and disassembly of the main body 3 and the base 2, making the ventilation device easy to install, disassemble and maintain.

[0025] In this embodiment, a rain shield 8 is fixedly connected to the inner wall of the main body 3, and a through groove 9 is provided on the outer surface of the rain shield 8. A movable plate 10 is slidably connected to the inner wall of the through groove 9.

[0026] In practical use, the rain shield 8 can block rain in rainy weather, and the movable plate 10 can close in rainy weather by sliding connection with the through groove 9 to cooperate with the rain shield 8 to achieve the rain-blocking function.

[0027] In this embodiment, a bidirectional screw 11 is rotatably connected to the inner wall of the main body 3, and an installation groove 12 is provided on the inner wall of the main body 3. A drive motor 13 is installed on the inner wall of the installation groove 12. The output end of the drive motor 13 is fixedly connected to the bidirectional screw 11. A connecting plate 14 is threadedly connected to one side of the outer surface of the bidirectional screw 11. The connecting plate 14 is fixedly connected to the movable plate 10.

[0028] In practical use, when the drive motor 13 is running, its output end can drive the bidirectional screw 11 to rotate. At this time, the bidirectional screw 11 can drive the movement of the movable plate 10 through the threaded movement with the connecting plate 14, controlling the opening and closing of the movable plate 10.

[0029] In this embodiment, a rotating shaft 15 is rotatably connected to the inner wall of the main body 3, and a fan blade 16 is fixedly connected to one side of the outer surface of the rotating shaft 15.

[0030] In practical use, the rising gas inside the factory can drive the fan blades 16 and the rotating shaft 15 to rotate, thereby accelerating the discharge of gas from the factory under the action of the fan blades 16.

[0031] In this embodiment, a solar panel 17 is installed on the upper surface of the rain shield 8, and an energy storage battery 18 is provided on the inner surface of the rain shield 8. The energy storage battery 18 is electrically connected to the drive motor 13.

[0032] In practical use, the solar panel 17 can supply power to the energy storage battery 18 when the sun shines during the day. The energy storage battery 18 can drive the drive motor 13 to run through electrical connection with the drive motor 13.

[0033] In this embodiment, a rain guide groove 19 is fixedly connected to the inner wall of the main body 3. The rain guide groove 19 penetrates the inner surface of the main body 3 and extends to one side of the outer surface of the main body 3.

[0034] In practical use, during rainy weather, rainwater falls down the rain shield 8 to the rain guide channel 19, and then is discharged from the main body 3 through the rain guide channel 19.

[0035] Working principle: In use, the trapezoidal frame 1 is placed on the roof where it is to be installed. The first screw 5 is used to connect and fix the trapezoidal frame 1 to the roof surface. Then, the base 2 is installed on the trapezoidal frame 1 through the sliding connection between the trapezoidal groove 4 and the base 2. Finally, the second screw 7 is used to install the baffle 6 to limit the position of the base 2 and prevent it from moving, thus facilitating the installation and disassembly of the main body 3 and the base 2. This allows for easy installation, disassembly, and maintenance of the ventilation device. The solar panel 17 on the rain shield 8 powers the energy storage battery 18. 18 can drive the drive motor 13 to run through electrical connection with the drive motor 13. On rainy days, the rain shield 8 can block the rainwater, and the rainwater will fall along the rain shield 8 to the rain guide groove 19 for discharge. When the weather is good, the drive motor 13 runs and its output end drives the bidirectional screw 11 to rotate and make threaded movement with the connecting plate 14. Then the connecting plate 14 drives the movable plate 10 to open, and the gas inside the factory rises, driving the rotating shaft 15 and the fan blade 16 to rotate. Since the movable plate 10 is in the open state, it is more conducive to ventilation and air exchange in the factory, improving the ventilation and air exchange efficiency.
