Description

Technical Field

[0001] This utility model relates to the field of football field technology, specifically to a ventilation device for a closed football field. Background Technology

[0002] As the name suggests, a closed football field is a football field with enclosed features. Compared to an open-air football field, a closed football field has obvious advantages. It is not affected by the external environment when used, and people can play football in a closed football field regardless of wind or rain.

[0003] Enclosed football fields, due to their enclosed nature, also have certain drawbacks, namely the necessity of installing a ventilation system; otherwise, the air inside the enclosed field will not circulate, causing inconvenience to those playing. Therefore, we propose a ventilation device for enclosed football fields. Utility Model Content

[0004] This invention provides a ventilation device for an enclosed football field, which has the advantage of being able to be opened and closed at any time, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A ventilation device for a closed football field is designed, including a support frame, a top cover on the top of the support frame, a linear screw drive device in the middle of the support frame, multiple first sealing plates on both sides of the support frame, a rotating shaft on the side of the first sealing plate near the linear screw drive device, the upper and lower ends of the rotating shaft being rotatably connected to the support frame, a strip arm parallel to the first sealing plate in the middle of the rotating shaft, the ends of the strip arms on the same side being rotatably connected to the connecting rod, a drive arm extending obliquely towards the linear screw drive device on each connecting rod, the end of the drive arm being rotatably connected to the linear screw drive device, the linear screw drive device pulling the two connecting rods away from or towards each other through the drive arm, so that the first sealing plates are stacked in the support frame or rotate out of the support frame.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 7 This utility model provides a technical solution: a ventilation device for an enclosed football field, including a support frame 1. The support frame 1 is a strip structure, which is a cube formed by welding multiple rods. In actual use, such as... Figure 7 As shown, the support frame is installed on the roof of the enclosed football field, and the roof and the support frame 1 are connected. Figure 1 and Figure 2 As shown, the top of the support frame 1 is provided with a top cover, which includes multiple top supports 3 distributed above the support frame 1. The top supports 3 are connected to the support frame 1 through a mounting frame 6. The top surface of the top supports 3 is provided with a canopy 4. The supports 3 and the canopy 4 are arched structures. In order to ensure that the support frame 1 is sealed, such as Figure 2 As shown, the two ends of the support frame 1 and the mounting bracket 6 are sealed by the second sealing plate 2, so that the support frame 1 and the mounting bracket 6 are sealed, and only the two sides of the support frame 1 are ventilated.

[0024] Furthermore, a lead screw linear drive device is provided in the middle of the support frame 1. The lead screw linear drive device includes a lead screw 7 located in the middle of the support frame. One end of the lead screw 7 is connected to the drive mechanism. The drive mechanism includes a drive motor 11 installed at one end of the lead screw 7. The drive motor 11 is installed on a motor bracket 12. The motor bracket 12 is connected to the support frame 1 through a first connecting frame 10.

[0025] A drive seat 14 is threaded onto the lead screw 7. Since the lead screw 7 has a certain length, in order to make the lead screw 7 more stable, the end of the lead screw 7 away from the drive motor 11 is rotatably set in the support 8. The support 8 is connected to the support frame 1 through the second connecting bracket 17. The second connecting bracket 17 and the first connecting bracket 10 are both located at the bottom of the support frame 1, and their two ends are connected to the support frame 1. The two can not only support the lead screw and the drive motor, but also strengthen the overall strength of the support frame 1.

[0026] Furthermore, such as Figure 2 and Figure 3As shown, in order to seal or allow ventilation on both sides of the support frame 1, multiple first sealing plates 5 are provided on both sides of the support frame 1. A rotating shaft 16 is provided on the side of the first sealing plate 5 near the lead screw linear drive device. The upper and lower ends of the rotating shaft 16 are rotatably connected to the support frame 1, so that each first sealing plate 5 can rotate freely. Each rotating shaft 16 has a strip-shaped arm 15 parallel to the first sealing plate 5 in its middle. Rotating the strip arm 15 drives the first sealing plate 5 to rotate, and the strip arm 15 also increases the lever arm for rotating the first sealing plate 5. The ends of the strip arms 15 on the same side are rotatably connected to connecting rods 9, and the two connecting rods 9 are parallel to each other. Figure 4 and Figure 5 As shown, the lead screw 7 is located parallel to the middle between the two connecting rods 9; Each connecting rod 9 is equipped with a drive arm 13 that extends obliquely towards the linear drive device of the lead screw, such as Figure 6 As shown, there is an angle between the drive arm 13 and the lead screw 7. The end of the drive arm 13 is rotatably connected to the linear drive device of the lead screw. Specifically, the end of the drive arm 13 away from the connecting rod 9 is rotatably connected to the drive seat 14. When the lead screw 7 rotates under the drive of the drive motor 11, the lead screw 7 can drive the drive seat 14 to reciprocate along its axial direction, that is, the drive seat 14 moves along... Figure 6 When moving in the direction indicated by the middle arrow B, the drive seat 14 simultaneously drives both drive arms 13 to pull the first sealing plate 5. Figure 3 and Figure 5 They are closed inside the support frame 1. At this time, the two adjacent first sealing plates 5 are stacked together end to end, and the multiple first sealing plates 5 seal the side of the support frame 1. And when drive seat 14 along Figure 6 When the movement is in the direction indicated by the middle arrow A, the drive seat 14 simultaneously drives both drive arms 13 to pull the first sealing plate 5. Figure 2 and Figure 4 The same opening mechanism is used, at which point the first sealing plate 5 is perpendicular to the lead screw 7, allowing both sides of the support frame 1 to connect with the outside. In summary, the lead screw linear drive device pulls the two connecting rods 9 away from or towards each other via the drive arm 13, causing the first sealing plate 5 to be stacked inside the support frame 1 or rotated out of the support frame 1.

[0027] When the first sealing plate 5 is closed, a sealed space is formed in the football field; when the first sealing plate 5 is opened, as... Figure 7 As shown, this allows hot air inside the stadium to flow out from the top, while fresh air from outside can enter through ventilation windows on the sides of the stadium, enabling air circulation within the stadium. In practical applications, the support frames 1 can be installed in rows on the stadium's roof.

[0028] Furthermore, such as Figure 1 As shown, both sides of the top bracket 3 and the canopy 4 extend to the outside of the support frame 1, so that the first sealing plate 5 is located below the canopy 4, which can prevent rainwater from falling into the support frame 1.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
