Description

Technical Field

[0001] This utility model relates to an energy-saving ventilation equipment for steel structure workshops, belonging to the technical field of ventilation equipment. Background Technology

[0002] Current steel structure factory buildings typically rely on built-in doors, windows, and roof vents for ventilation, which is ineffective. Installing separate ventilation equipment on the factory building can accelerate airflow and achieve better ventilation and heat dissipation.

[0003] Patent CN217715283U discloses an energy-saving factory ventilation device, including a protective box, a mounting box, a drive shaft, blades, a first bevel gear, a second bevel gear, a driven shaft, fan blades, and a cooling fan. The protective box is connected to the roof of the factory building. The mounting box is connected above the protective box, and the drive shaft is installed inside the mounting box. One end of the drive shaft extends out of the mounting box and connects to the blades, while the other end is rotatably connected to the inner wall of the mounting box. The first bevel gear is mounted on the drive shaft inside the mounting box, and the first bevel gear meshes with the second bevel gear. The second bevel gear is connected to one end of the driven shaft, and the other end of the driven shaft passes through the protective box and the factory roof, extending into the factory building and connecting to the cooling fan. Fan blades are mounted on the driven shaft inside the protective box. The cooling fan is driven by airflow to ventilate and cool the steel structure factory building, achieving a good ventilation effect.

[0004] Research has shown that while the aforementioned methods can utilize wind power to rotate the cooling fans and ventilate the steel structure workshop, they are limited in effectiveness when there is insufficient or no wind. Therefore, this invention provides an energy-saving ventilation device for steel structure workshops. Utility Model Content

In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0027] like Figures 1-4 As shown, an energy-saving steel structure factory ventilation system includes a roof 1. A set of support frames 2 are detachably and fixedly connected to the top of the roof 1. A mounting box 3 is provided on the top of the set of support frames 2. A wind-driven mechanism is rotatably connected to the right end of the mounting box 3. A mounting shaft 4 is rotatably connected to the bottom wall of the mounting box 3. A first bevel gear 5 is provided at the top of the mounting shaft 4. The lower end of the mounting shaft 4 extends to the lower end of the roof 1. A cooling fan blade 6 is installed at the bottom end of the mounting shaft 4. A drive motor 7 is installed on the left end face of the mounting box 3. An extension shaft 8 is connected to the output shaft of the drive motor 7. A movable shaft 9 is slidably connected to the extension shaft 8 through a sliding component. A second bevel gear 10 is installed on the right end of the movable shaft 9. A control plate 11 is rotatably connected to the movable shaft 9. The top of the control plate 11 is slidably engaged with the top of the inner wall of the mounting box 3. A control mechanism for controlling the movement of the control plate 11 is installed inside the mounting box 3.

[0028] In the above technical solution, this utility model, by setting a control mechanism, allows the control motor 15 to start and drive the threaded rod 16 to rotate in the absence of wind, which in turn drives the control board 11 to move towards the first bevel gear 5. This, in conjunction with the sliding assembly, drives the moving shaft 9 and the second bevel gear 10 towards the first bevel gear 5. When the second bevel gear 10 engages with the first bevel gear 5, the drive motor 7 rotates, causing the first bevel gear 5 to rotate, thus driving the cooling fan blades 6 to rotate for heat dissipation in the absence of wind. In the presence of wind, the control motor 15 can control the threaded rod 16 to rotate in the opposite direction, driving the control board 11 to disengage the second bevel gear 10 from the first bevel gear 5. Under the influence of wind, the wind-driven mechanism drives the first bevel gear 5 to rotate for heat dissipation. This utility model achieves heat dissipation by driving the cooling fan blades 6 to rotate via the wind-driven mechanism in the presence of wind, and by driving the motor 7 to rotate the cooling fan blades 6 to rotate for heat dissipation in the absence of wind, thus overcoming the limitations of the prior art.

[0029] In this utility model, the sliding component includes a set of sliding grooves 12, which are symmetrically opened on the extension shaft 8. A slider 13 is slidably connected in the sliding groove 12. A U-shaped connecting frame 14 is installed on the end face of the slider 13 away from the outer wall of the extension shaft 8. The right end face of the U-shaped connecting frame 14 is fixedly connected to the left end face of the moving shaft 9.

[0030] In the above technical solution, by setting a sliding component, under the drive of the control board 11, the extension shaft 8 and the moving shaft 9 slide to extend or shorten, so that the drive motor 7 can drive the first bevel gear 5 to rotate or disengage from the rotational engagement with the first bevel gear 5.

[0031] In this utility model, the control mechanism includes a control motor 15, which is fixedly connected to the inner right side wall of the mounting box 3. A threaded rod 16 is connected to the output shaft of the control motor 15, and the threaded rod 16 is threadedly connected to the control plate 11.

[0032] In the above technical solution, by setting a control motor 15, the start of the control motor 15 can drive the threaded rod 16 to rotate. The rotation of the threaded rod 16 can drive the control plate 11, which is threadedly connected to it, to move, and then drive the second bevel gear 10 to move, providing power for the meshing or disengagement of the first bevel gear 5 and the second bevel gear 10.

A third bevel gear 18 is provided at the left end of the drive shaft 17, and a drive fan blade 19 is installed at the right end of the drive shaft 17. The third bevel gear 18 meshes with the first bevel gear 5.

[0034] In the above technical solution, by setting up a wind-driven mechanism, when there is wind, the wind drives the drive fan blade 19 to rotate, and with the cooperation of the drive shaft 17, the third bevel gear 18, the first bevel gear 5 and the mounting shaft 4, the cooling fan blade 6 is driven to rotate.

[0035] In this utility model, the mounting shaft 4, drive shaft 17 and extension shaft 8 are rotatably connected to the mounting box 3 via the first bearing 20.

[0036] In this invention, the moving shaft 9 and the control board 11 are rotatably connected by a second bearing 21.

[0037] In this invention, a protective cover 22 is provided on the left end face of the mounting box 3, and the drive motor 7 is located inside the protective cover 22. The protective cover 22 is used to protect the drive motor 7.

[0038] In this invention, a waterproof cover 23 is provided at the location where the mounting shaft 4 passes through the roof 1, and louvers 24 are provided on all four side walls of the waterproof cover 23.
