Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a large-span steel truss structure for sports stadiums with fire protection functions. Background Technology

[0002] Sports stadiums are professional venues for sports training, competitions, and physical exercise. They are a general term for various sports venues specifically built to meet the needs of sports training, competitions, and mass sports consumption. During construction, sports stadiums require a large-span steel truss structure with a span of 58 meters to support the roof. However, existing large-span steel truss structures generally lack fire-fighting structures. When a fire occurs in a sports stadium, it is impossible to control the fire at the source, concentrate firefighting efforts, or increase water pressure, leading to reduced firefighting efficiency and effectiveness. Furthermore, they generally lack dedicated fire monitoring structures, resulting in the inability to extinguish fires promptly, allowing the fire to spread and reducing the effectiveness of fire monitoring. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] See Figures 2-4 A large-span steel truss structure for a sports stadium with fire protection function includes a steel truss main body 1, fire protection components 2, drive components 3, support plates 4, and camera components 5. The fire protection components 2 are installed on the steel truss main body 1. The drive components 3 are installed on the inner wall of one side of the steel truss main body 1. The support plates 4 are fixedly connected to the outer wall of one side of the steel truss main body 1, and the camera components 5 are installed on the support plates 4. First connecting plates 6 are welded to the outer walls of both sides of the steel truss main body 1. Connecting holes 7 are opened on one side of the first connecting plates 6. Bolts are inserted into the connecting holes 7 to fix the first connecting plates 6 on the steel truss main body 1 to the roof. A water pump 8 is installed at one end of a water supply pipe 203. A water pump pipe 9 is installed on the outer wall of the bottom end of the water pump 8. The water pump pipe 9 is placed inside the swimming pool. The water pump 8 is started to draw circulating water from the swimming pool through the water pump pipe 9, which facilitates the extraction of circulating water.

[0028] Firefighting component 2 includes a first rotating hole 201, a second connecting plate 202, a water supply pipe 203, a water injection pipe 204, a first slip ring 205, a water baffle 206, a rotating pipe 207, a sealing baffle 208, a sleeve 209, a first annular sliding groove 2010, a water spray plate 2011, and a waterproof gasket 2012. The second connecting plate 202 is fixedly connected to the inner wall of the top of the steel truss main body 1. The water supply pipe 203 is fixedly connected to the outer wall of the bottom end of the second connecting plate 202. Water injection pipes 204 are distributed and connected through the bottom end of the water supply pipe 203. A rotating pipe 207 is sleeved on one inner wall of the water injection pipe 204. A sleeve 209 is fixedly connected to one outer wall of the rotating pipe 207. A waterproof gasket 2012 is installed on the inner wall of the bottom end of the sleeve 209. A first slip ring 205 is fixedly connected to one outer wall of the water injection pipe 204. A corresponding waterproof gasket 2012 is installed on one inner wall of the sleeve 209. A first annular groove 2010 is provided at the position of the first slip ring 205. A sealing baffle 208 is fixedly connected to the inner wall of the top end of the rotating pipe 207. A water baffle 206 is fixedly connected to one side of the water injection pipe 204 corresponding to the position of the sealing baffle 208. A water spray plate 2011 is connected through the outer wall of the bottom end of the rotating pipe 207. A first rotating hole 201 is provided at the bottom end of the steel truss body 1 corresponding to the position of the rotating pipe 207. The rotating pipe 207 on the water spray plate 2011 can be rotated and adjusted along the first rotating hole 201, which can adjust the water spray range and water spray pressure of the water spray plate 2011. The water baffle 206 and the sealing baffle 208 are both semi-circular in shape, and the bottom end of the water baffle 206 is sealed to the outer wall of the sealing baffle 208. By overlapping or offsetting the water baffle 206 and the sealing baffle 208, the water spray structure can be turned on and off.

[0029] Working principle: First, the main steel truss 1 is erected on the stadium. Then, the water pump 8's pumping pipe 9 is placed inside the swimming pool. The pump 8 is started to draw circulating water from the swimming pool through the pumping pipe 9 and inject it into the water supply pipe 203 and the water injection pipe 204. At this time, the first motor 307 is started to rotate the first gear 308. Then, under the action of the second rack 306, the slide plate 302 on the first rack 303 moves along the slide rail 301. The first rack 303 drives the second gear 309 to rotate, causing the first gear inside the sleeve 209 to rotate. The annular chute 2010 rotates 180 degrees along the first slip ring 205 on the water injection pipe 204, causing the baffle plate 206 to overlap with the sealing baffle plate 208. Then, circulating water is injected through the water injection pipe 204 into the spray plate 2011 on the rotating pipe 207. The circulating water is then sealed by the waterproof gasket 2012 inside the sleeve 209. The spray plate 2011 is used to extinguish the fire. Fire protection structures can be installed on steel truss structures, which can reduce manual fire fighting in the event of a fire, reduce the burden on manpower, and improve the fire fighting effect.

[0030] Example 2

[0031] See Figure 2 , Figure 4 and Figure 5 The drive assembly 3 includes a slide rail 301, a slide plate 302, a first rack 303, a connecting square rod 304, a magnetic adsorption block 305, a second rack 306, a first motor 307, a first gear 308, and a second gear 309. A second gear 309 is fixedly connected to one outer wall of the sleeve 209. A first rack 303 is meshed and installed on one outer wall of the second gear 309. A slide plate 302 is fixedly connected to one outer wall of the first rack 303. Slide rails 301 are welded to one inner wall of the steel truss body 1, corresponding to the positions of the slide plate 302. A connecting square rod 304 is fixedly connected to the top outer wall of one first rack 303. Magnetic adsorption blocks 305 are distributed and installed on the bottom outer wall of the connecting square rod 304, with the bottom ends of the magnetic adsorption blocks 305 adhering to the outer wall of the first rack 303. A connecting square rod 304 is fixedly connected to the top outer wall of the slide plate 302. A second rack 306 is connected, and a first gear 308 is meshed on the outer wall of the top of the second rack 306. A first motor 307 is embedded on the inner wall of one side of the steel truss body 1, and one end of the output shaft of the first motor 307 is fixed to the outer wall of the first gear 308. When the first motor 307 is started, the first gear 308 is rotated. Then, under the action of the second rack 306, the slide plate 302 on the first rack 303 can move along the slide rail 301. The first rack 303 is a bevel rack, and the second gear 309 is a bevel gear. One side of the first rack 303 is perpendicularly meshed with the outer wall of the second gear 309. The first rack 303 drives the second gear 309 to rotate, so that the first annular groove 2010 in the sleeve 209 rotates 180 degrees along the first slip ring 205 on the water injection pipe 204.

[0032] When firefighting is required at a designated location, the magnetic adsorption blocks 305 at other locations are closed. At this time, the first motor 307 is activated, causing the first gear 308 to rotate. Then, under the action of the second rack 306, the sliding plate 302 on the first rack 303 moves along the slide rail 301. The magnetic adsorption block 305 on the connecting square rod 304 then drives the first rack 303 at the designated location. The first rack 303 drives the second gear 309 to rotate, causing the first annular slide plate inside the sleeve 209 to move. The trough 2010 rotates 180 degrees along the first slip ring 205 on the water injection pipe 204, causing the baffle plate 206 to overlap with the sealing baffle plate 208. This allows water to flow through this location while shutting off water spraying at other locations. All circulating water is injected into the spray plate 2011 at this location through the water injection pipe 204, increasing water pressure and reducing water waste. This allows for concentrated fire suppression at the fire point, increasing water pressure and thus extinguishing the fire more quickly, thereby increasing firefighting efficiency.

[0033] Example 3

[0034] See Figure 1 and Figure 6 The camera assembly 5 includes a second motor 501, a third gear 502, a second rotating hole 503, a second annular groove 504, a second slip ring 505, a fourth gear 506, a threaded hole 507, a camera 508, and a lead screw 509. The top of the support plate 4 has a second annular groove 504, and a second slip ring 505 is slidably connected to one side of the second annular groove 504. The fourth gear 506 is fixedly connected to the outer wall of the top of the second slip ring 505. The camera 508 is installed below the support plate 4, and the lead screw 509 is installed on the outer wall of the top of the camera 508. A second rotating hole 503 is opened on one side of the support plate 4 corresponding to the position of the lead screw 509. A threaded hole 507 is opened in the middle of the fourth gear 506 corresponding to the position of the lead screw 509. The third gear 502 is meshed on the outer wall of one side of the fourth gear 506. The second motor 501 is embedded in the top of the support plate 4, and the top of the output shaft of the second motor 501 is fixedly connected to the outer wall of the third gear 502.

[0035] When fire monitoring of a sports venue is required, camera 508 is activated to monitor the venue. Then, the second motor 501 is started to make the third gear 502 rotate periodically, which in turn drives the second slip ring 505 on the fourth gear 506 to rotate periodically along the second annular groove 504. Then, under the action of the threaded hole 507, the lead screw 509 on the camera 508 rotates and rises along the second rotating hole 503, thereby monitoring the camera 508 at different heights to ensure the safety of the venue. It can monitor the venue for fires and can rotate and rise to monitor, so that fires can be extinguished in time when they occur, improving the fire detection effect.
