Description

Technical Field

[0001] This utility model relates to the field of steel structure factory building technology, specifically a ventilation structure for steel structure factory buildings. Background Technology

[0002] Steel structure industrial plants refer to factories whose main load-bearing components are made of steel and constructed with steel structures. They are one of the main building types. With the rapid development of industry, steel structures have gradually replaced traditional concrete and brick structures in my country's buildings.

[0003] A search revealed that Chinese Utility Model Patent Publication No. CN209524596U discloses a ventilation structure for a steel structure factory building. This prior art involves installing ventilation openings on the roof of the steel structure factory building, with a reversible air guide plate installed on the ventilation opening. The air guide plate flips upward, allowing air to enter the ventilation opening through the air guide plate, thereby ventilating and dissipating heat inside the steel structure factory building.

[0004] The technical solution has the following defects: after the air guide plate is flipped upwards and tilted, the two sides of the air guide plate are open. After the air comes into contact with the air guide plate, it may be blocked by the air guide plate and some air may escape from the two sides of the air guide plate. This results in only a small amount of air being guided by the air guide plate and entering the steel structure workshop. Therefore, it is necessary to improve the ventilation structure in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation structure for steel structure workshops to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilation structure for steel structure workshops, comprising:

[0008] A fixing seat installed on the top of a steel structure workshop, the lower side of which extends into the interior of the steel structure workshop;

[0009] A rotating seat is coaxially mounted on the fixed seat, the lower end of the rotating seat extends below the fixed seat, and the rotating seat can rotate freely on the fixed seat. The upper side of the rotating seat extends to the top of the steel structure factory building.

[0010] An air guide plate is hinged to the upper end face of the rotating seat, and the air guide plate is driven to rotate by a flipping mechanism installed in the rotating seat;

[0011] An escape prevention part is installed in the rotating seat. The upper end face of the escape prevention part is inclined and abuts against the bottom surface of the air guide plate after it is flipped upward and into place. An air guide port is opened on the outer wall of the escape prevention part away from the air guide plate on the side of the rotating fulcrum on the rotating seat.

[0012] Furthermore, a ring rack is coaxially and fixedly sleeved on the lower side of the fixed base, a motor plate is fixedly connected to the periphery of the rotating base, a motor is vertically mounted on the motor plate, and a gear is fixedly sleeved on the output shaft of the motor, the gear meshing with the ring rack.

[0013] Furthermore, a bearing groove is provided on the upper end face of the fixed seat, and a bearing is engaged and installed in the bearing groove, and the rotating seat is inserted and installed in the inner ring of the bearing.

[0014] Furthermore, a filter screen is installed inside the rotating base.

[0015] Furthermore, the filter screen is installed on the underside of the rotating base.

[0016] Furthermore, a first ear block is fixedly connected to the inner wall of the rotating seat, and a guide post is vertically inserted through the first ear block. A second ear block is fixedly connected to the inner side wall of the anti-escape part, and a guide hole is opened on the surface of the second ear block to allow the guide post to pass freely. An elastic element is provided between the first ear block and the second ear block.

[0017] Furthermore, the elastic element is a spring that is wrapped around the periphery of the guide post, and the two ends of the spring elastically abut against the first lug and the second lug, respectively.

[0018] Furthermore, the first ear block is provided in two parts and is symmetrically arranged along the axis of the rotating seat.

[0019] Furthermore, the flipping mechanism includes a movable seat hinged to the inner wall of the rotating seat, a cylinder is mounted on the movable seat, a connecting block is connected to the end of the cylinder rod of the cylinder, and the connecting block is hinged to the downward-facing side of the air guide plate.

[0020] Furthermore, the downward-facing side of the air guide plate is provided with a rubber layer.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting up air guide plates and escape prevention sections, the escape prevention sections have air guide ports. When the air comes into contact with the air guide plates, it is blocked by the inner wall of the escape prevention section and cannot escape. Instead, it enters the fixed base. Compared with the existing technology, this increases the airflow into the steel structure workshop and increases the ventilation volume of the steel structure workshop.

[0023] 2. By setting guide posts and elastic elements, when the air guide plate is stored in the rotating seat, the air guide plate will exert a downward squeezing force on the anti-escape part, so that the anti-escape part overcomes the elastic resisting force of the elastic element on the second ear block, and then moves into the rotating seat and is stored in the rotating seat. When the air guide plate flips upward, the elastic potential energy of the elastic element is released and drives the anti-escape part to move upward.

[0024] 3. By setting up a flipping mechanism, the air guide plate is driven to flip up and down, which facilitates timely flipping of the air guide plate in windy weather conditions, so that the interior of the steel structure factory can be ventilated in a timely manner. In addition, the motor drives the gear to rotate, and through the meshing of the gear and the ring rack, the rotating seat is driven to rotate, so that the air guide plate can guide the airflow in different directions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figures 1-5 This utility model provides a technical solution: a ventilation structure for a steel structure factory building, including a fixed seat 8 installed on the top of the steel structure factory building. The roof of the steel structure factory building has an installation opening for the fixed seat 8. The lower side of the fixed seat 8 extends into the interior of the steel structure factory building, and the upper side of the fixed seat 8 protrudes to the roof of the steel structure factory building and is provided with a water-stop edge 2. The bottom surface of the water-stop edge 2 abuts against the roof of the steel structure factory building through a sealing ring. The upper end face of the fixed seat 8 is provided with a bearing groove, and a bearing 15 is engaged in the bearing groove. A rotating seat 1 is inserted into the inner ring of the bearing 15, thereby enabling the rotating seat 1 to rotate coaxially and be connected to the fixed seat 8. The lower end of the rotating seat 1 extends below the fixed seat 8, and the upper side of the rotating seat 1 extends to the top of the steel structure factory building.

[0033] A ring rack 3 is coaxially and fixedly sleeved on the lower side of the fixed seat 8. A motor plate is fixedly connected to the periphery of the rotating seat 1. A motor 10 is vertically mounted on the motor plate. A gear 11 is fixedly sleeved on the output shaft of the motor 10. The gear 11 meshes with the ring rack 3. The output shaft of the motor 10 rotates and drives the gear 11 to rotate. Then, through the meshing of the gear 11 and the ring rack 3, the rotating seat 1 is driven to rotate. In addition, a guide plate 7 is hinged to the upper end face of the rotating seat 1. A movable seat 13 is hinged to the inner side wall of the rotating seat 1. A cylinder 12 is mounted on the movable seat 13. A connecting block 17 is connected to the end of the cylinder rod of the cylinder 12. The connecting block 17 is hinged to the downward-facing side of the guide plate 7. A filter screen 9 is installed inside the rotating seat 1. The filter screen 9 is installed on the lower side of the rotating seat 1, which can prevent leaves and other debris from entering the steel structure workshop through the rotating seat 1. At the same time, the filter screen 9 is installed on the lower side of the rotating seat 1 to avoid interference with the cylinder 12 and other components.

[0034] An escape prevention part 6 is coaxially engaged within the rotating base 1. This escape prevention part 6 can also slide freely up and down within the rotating base 1. The upper surface of the escape prevention part 6 is inclined and abuts against the bottom surface of the air guide plate 7 after it has been flipped upwards into position. Furthermore, a rubber layer (not shown in the figure) is provided on the downward-facing side of the air guide plate 7. This rubber layer ensures good sealing between the inclined surface of the escape prevention part 6 and the contact surface of the air guide plate 7. Simultaneously, the rubber layer also buffers the contact process between the surface of the escape prevention part 6 and the surface of the air guide plate 7. An air guide port 16 is provided on the outer wall of the escape prevention part 6 on the side away from the air guide plate 7, at the rotation fulcrum of the rotating base 1. A first lug is fixed to the inner wall of the rotating base 1. Block 14, a guide post 5 is vertically inserted through the first ear block 14, a second ear block is fixed to the inner wall of the anti-escape part 6, the surface of the second ear block has a guide hole for the guide post 5 to pass freely, a spring 4 is provided between the first ear block 14 and the second ear block, the spring 4 is wrapped around the periphery of the guide post 5 and the two ends of the spring 4 elastically abut against the first ear block 14 and the second ear block respectively in the direction of the spring force. In the initial state, the spring 4 is in a certain compressed state, so that the spring 4 has an upward elastic abutting force on the second ear block. In addition, there are two first ear blocks 14 and they are symmetrically arranged along the axis of the rotating seat 1, so that the two guide posts 5 can generate a uniform supporting force on the anti-escape part 6.

[0035] The working principle of this utility model is as follows: When ventilation and heat dissipation are required inside the steel structure workshop, the wind direction is first determined, then the external power supply is connected and the motor 10 is started. When the motor 10 starts, its output shaft rotates and drives the gear 11 to rotate. Then, through the meshing of the gear 11 and the ring rack 3, the drive rotating seat 1 is rotated, so that the rotating seat 1 rotates to a suitable angle.

[0036] When cylinder 12 is activated, its cylinder rod extends, driving connecting block 17 to move upwards. This, in turn, causes the air guide plate 7 to swing upwards along the hinge point with the rotating seat 1. During this swinging motion, the elastic potential energy of spring 4 is released, driving the second ear block to move upwards, causing the anti-escape part 6 to move upwards simultaneously. Once the cylinder rod of cylinder 12 has extended to its full length, the upper inclined surface of the anti-escape part 6 abuts against the downward-facing side of the air guide plate 7, ensuring that the air guide port 16 on the anti-escape part 6 faces the wind direction. Thus, the airflow will be directed from... Air enters the rotating seat 1 through the air inlet 16. When the air comes into contact with the air guide plate 7, it is blocked by the inner wall of the anti-escape part 6 and cannot escape. Instead, it enters the fixed seat 8, the inner side of the rotating seat 1, and then enters the steel structure workshop. Compared with the prior art, this increases the airflow into the steel structure workshop and increases the ventilation volume of the steel structure workshop. It should be noted that in this embodiment, the upward flip angle of the air guide plate 7 is fixed to ensure that the inclined surface on the upper side of the anti-escape part 6 abuts against the downward side of the air guide plate 7.
