Description

Technical Field

[0001] This invention belongs to the field of anchor bolt technology, specifically the double-deck drainage structure of an all-aluminum structure helipad. Background Technology

[0002] Currently, some helipads are built on rooftops and are used to park helicopters. As the main activity area for helicopters, the helipads have clear signs to help people park their helicopters there.

[0003] Regarding existing related technologies, the inventor believes that they often have the following drawbacks: Traditional helipad structures are generally made of concrete, which has poor seismic performance, is prone to surface cracking, and is prone to leakage. After long-term use, cracking can easily lead to leakage of the panels. If there is an elevator machine room below, it poses a safety hazard, causes inconvenience to the owner's life and work, and affects normal use. Moreover, surface cracking affects the aesthetics, resulting in high maintenance and repair costs. This technology generally does not have an orderly drainage structure and adopts free drainage measures. In addition to the risk of cracking and leakage, rainwater will cause pollution of the walls and affect the aesthetics. Therefore, this invention provides a double-layer deck drainage structure for all-aluminum helipads. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: The all-aluminum structure helipad double-deck drainage structure of this invention includes an aluminum alloy frame beam, special fasteners, an upper deck, a lower deck, an aluminum alloy water trough, and core-pulling anchors; the lower deck is connected to the aluminum alloy frame beam using special fasteners, and first fasteners are provided on both sides of the lower deck, second fasteners are provided on both sides of the upper deck, and third fasteners are evenly provided on the side of the lower deck and the upper deck that are close to each other. The lower deck and the upper deck are connected by embedded locking of the third fasteners. The aluminum alloy water trough is fixed to the upper and lower decks using core-pulling anchors. An aluminum pipe is fixedly connected inside the aluminum alloy water trough, and a PVC pipe is fixedly connected to the bottom side wall of the aluminum pipe. Drainage holes are evenly opened on the top surface of the upper deck. The aluminum alloy frame beams are tightly connected to the main structure via pre-embedded anchor bolts. The lower deck is connected to the aluminum alloy frame beams using specialized fasteners. Multiple sets of embedded locking fasteners on the lower deck can be connected using the first fastener, and multiple sets of embedded locking fasteners on the upper deck can be connected using the second fastener. The upper and lower decks are connected by a third fastener, forming a complete panel structure system. The aluminum alloy water trough is fixed to the upper and lower decks using pull-core anchors. Aluminum pipes connect to the bottom of the water trough, and PVC pipes connect to the bottom of the aluminum pipes. Drainage holes are provided on the upper deck, spaced 20cm-22cm apart. During rain, rainwater falls onto the upper deck through these drainage holes, flows down the lower deck into the aluminum alloy water trough, and then drains to the roof through the aluminum pipes. The entire drainage process is concealed and orderly. Because the helipad surface uses an all-aluminum structure, it will not crack or rust, has an aesthetically pleasing appearance, and fulfills its service value for the helipad.

[0006] Preferably, when the first, second, and third clips are engaged, there is a connecting seam, and the connecting seam is filled with silicone. By injecting silicone into the connecting seam before the first, second, and third clips are connected by embedded locking, the connection is more secure and the connection between the decks is tighter. Since the connecting seam is connected with silicone and embedded locking, rainwater will not leak, thereby improving the overall drainage and sealing effect.

[0007] Preferably, a motor is fixedly mounted on the inner wall of the aluminum tube via a bracket. A rotating shaft is fixedly connected to the output end of the motor. Multiple sets of connecting rods are fixedly connected to the surface of the rotating shaft. A sliding rod is slidably connected within each connecting rod. A scraper is fixedly connected to the end of the sliding rod away from the connecting rod. The side of the scraper away from the sliding rod is in contact with the inner wall of the aluminum tube. A spring is fixedly connected between the connecting rod and the scraper. An isosceles triangular apex block is fixedly connected to the inner wall of the aluminum tube. Because the water carries sludge during drainage, some of this sludge adheres to the aluminum tube. After rain, the sludge clumps on the inner wall of the aluminum tube, and as the sludge accumulates... The increasing amount of sludge will affect the drainage effect of the aluminum pipe. During heavy rain, rainwater cannot be discharged from the aluminum pipe in time. At this time, the motor can be set by the controller to start the motor periodically. When the motor starts, the shaft will rotate under the drive of the motor. At this time, the scraper can scrape off the sludge on the inner wall of the aluminum pipe, thereby improving the drainage effect of the aluminum pipe. When the scraper moves, it will pass through the inclined surface of the top block, causing the slide rod to retract into the connecting rod. Then the spring will push the scraper, causing the scraper to vibrate, thereby shaking off the impurities on the side of the scraper and preventing the sludge from remaining and accumulating on the scraper, which will affect the scraping effect.

[0008] Preferably, a flexible hollow block is fixedly installed on one side of the scraper, and a set of piercing cones is fixedly connected to the side of the hollow block away from the scraper. When the scraper cleans the sludge, some of the sludge will accumulate on the hollow block, and the rest will fall directly from the aluminum pipe. When the scraper moves, the piercing cones will break the sludge, which will facilitate the subsequent discharge of the sludge from the aluminum pipe. At the same time, the broken sludge can be better scraped off by the scraper. The hollow block will deform under the pressure of the piercing cones. After the piercing cones have completely passed through the sludge, the hollow block will return to its original shape, thereby discarding the sludge remaining on the hollow block and further improving the cleaning effect of the residual sludge. At the same time, the hollow block will shake, which will also shake off the sludge on the piercing cones.

[0009] Preferably, the scraper has a hollow structure, the hollow block is connected to the interior of the scraper, the hollow block stores water, and the hollow block has a shrinkage hole corresponding to the position of the piercing cone. The piercing cone has a through-hole for water discharge. When the hollow block is squeezed and deformed, the shrinkage hole will open, and the water inside the hollow block will be sprayed onto the sludge from the water discharge hole of the piercing cone, thus wetting the sludge and improving the cleaning effect of the scraper on the sludge.

[0010] Preferably, the top of the scraper is provided with a water inlet groove, and a filter screen is fixedly installed on the inner wall of the water inlet groove. A sponge block is provided inside the scraper, and a sealing block is fixedly connected to the top of the sponge block. When it rains, rainwater will be discharged from the aluminum pipe. At this time, the rainwater will pass through the scraper, allowing the rainwater to enter the scraper from the water inlet groove, thereby achieving the function of automatically collecting and storing rainwater, thus saving water resources. At the same time, the filter screen can filter impurities in the water and prevent impurities from entering the scraper. As the water level in the scraper rises, the sponge block will float upward. After the water in the scraper reaches its maximum capacity, the sealing block will seal the water inlet groove. Then, when the hollow block deforms, the water in the scraper will be squeezed out onto the sludge.

[0011] Preferably, the sealing block is uniformly and fixedly connected with a drain rod, the top surface of the sponge block is fixedly connected with a cylinder, the filter screen is made of elastic material, and the scraper is provided with a discharge mechanism. During the process of the sealing block sealing the water inlet tank, the drain rod can unclog the mesh of the filter screen to prevent sludge from clogging the mesh. Then, as the sealing block continues to rise, the cylinder will push the filter screen, causing it to deform and arch upwards, allowing impurities to slide down to the discharge mechanism for discharge. This cleans and discharges all impurities from the filter screen, preventing the impurities unclogged by the drain rod from remaining on the filter screen and causing the mesh to clog again.

[0012] Preferably, the discharge mechanism includes a set of guide channels, which are formed inside the scraper and communicate with the inlet channel. The scraper has a storage tank communicating with the guide channels. The guide channels are inclined, and a push plate is slidably connected to the inner wall of the storage tank. A fixing rod is fixedly connected to the bottom surface of the push plate, and the top surface of the push plate is inclined. When the filter screen is arched upwards, impurities slide off the filter screen to both sides, then enter the storage tank through the guide channels, and fall onto the push plate. When the sealing block seals the inlet channel, the sealing block pushes the fixing rod, causing the fixing rod to push the push plate out of the storage tank. The impurities on the push plate then slide onto the top surface of the scraper for discharge, thus automatically discharging impurities from the filter screen.

[0013] Preferably, a hollow elastic block is uniformly fixedly connected to the side of the top block near the hollow block, and air holes are uniformly opened on the elastic block; when the scraper passes the side of the top block, it will squeeze the elastic block, and the gas inside the elastic block will be discharged from the air holes. At this time, the gas will be blown onto the hollow block, thereby blowing away the impurities on the hollow block, thereby further improving the effect of removing impurities from the hollow block.

[0014] Preferably, a vertically arranged guide rod is fixedly connected inside the scraper, and the interior of the sponge block is slidably connected to the surface of the guide rod; by means of the guide rod, the sponge block can move vertically, allowing the sealing block to be aligned with the position of the water inlet tank, thus preventing the problem of the sealing block not being aligned with the water inlet tank for sealing.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. During rainfall, rainwater falls onto the upper deck through the drain holes, then flows down the lower deck into the aluminum alloy gutters, and finally drains to the roof through aluminum pipes. The entire drainage process is concealed and orderly. Because the helipad surface is made entirely of aluminum, it will not crack or rust, and its aesthetic appearance enhances its service value.

[0017] 2. By injecting silicone into the joint before connecting the first, second, and third clips with embedded locking, the connection becomes more secure and the connection between the decks becomes tighter. Because the joint is connected with silicone and embedded locking, rainwater will not leak, thus improving the overall drainage and sealing effect. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 7As shown in the embodiment of the present invention, the double-deck drainage structure of the all-aluminum apron includes an aluminum alloy frame beam 1, special fasteners 2, an upper deck 4, a lower deck 3, an aluminum alloy water trough 6, and pull-core anchors 9. The lower deck 3 is connected to the aluminum alloy frame beam 1 by special fasteners 2. First fasteners 5 are provided on both sides of the lower deck 3, and second fasteners 10 are provided on both sides of the upper deck 4. Third fasteners 11 are evenly distributed on the side of the lower deck 3 and the upper deck 4 closest to each other. The lower deck 3 and the upper deck 4 are connected by embedded locking of the third fasteners 11. The aluminum alloy water trough 6 is fixed to the upper and lower decks 3 by pull-core anchors 9. An aluminum pipe 7 is fixedly connected inside the aluminum alloy water trough 6, and a PVC pipe 8 is fixedly connected to the bottom side wall of the aluminum pipe 7. Drainage holes are evenly distributed on the top surface of the upper deck 4. The aluminum alloy frame... Beam 1 is tightly connected to the main structure via pre-embedded anchor bolts. The lower deck 3 is connected to the aluminum alloy frame beam 1 using special fasteners 2. Multiple sets of lower deck 3 can be connected by embedded locking using the first clip 5, and multiple sets of upper deck 4 can be connected by embedded locking using the second clip 10. The upper deck 4 and lower deck 3 are connected by embedded locking using the third clip 11, forming a complete panel structure system. The aluminum alloy water trough 6 is fixed to the upper and lower decks 3 using pull-out anchors 9. The water trough is connected to an aluminum pipe 7, and the lower part of the aluminum pipe 7 is connected to a PVC pipe 8. Drainage holes are provided on the upper deck 4, spaced 20cm-22cm apart. When it rains, rainwater falls onto the upper deck 4 through the drainage holes, flows down the lower deck 3 into the aluminum alloy water trough 6, and then drains to the roof through the aluminum pipe 7. The entire drainage process is concealed and orderly. Because the helipad surface uses an all-aluminum structure, it will not crack or rust, has an aesthetically pleasing appearance, and realizes the service value of the helipad.

[0031] When the first buckle 5, the second buckle 10, and the third buckle 11 are engaged, there is a connection seam, which is filled with silicone. By injecting silicone into the connection seam before the first buckle 5, the second buckle 10, and the third buckle 11 are connected by embedded locking, the connection is more secure and the connection between the decks is tighter. Because the connection seam is connected with silicone and embedded locking, rainwater will not leak, thereby improving the overall drainage and sealing effect.

[0032] A motor 12 is fixedly mounted on the inner wall of the aluminum tube 7 via a bracket. A rotating shaft 13 is fixedly connected to the output end of the motor 12. Multiple connecting rods 14 are fixedly connected to the surface of the rotating shaft 13. A sliding rod 15 is slidably connected within each connecting rod 14. A scraper 16 is fixedly connected to the end of the sliding rod 15 away from the connecting rod 14. The side of the scraper 16 away from the sliding rod 15 is in contact with the inner wall of the aluminum tube 7. A spring 17 is fixedly connected between the connecting rod 14 and the scraper 16. An isosceles triangular apex block 18 is fixedly connected to the inner wall of the aluminum tube 7. Because the water contains sludge during drainage, some of this sludge adheres to the aluminum tube 7. After rain, the sludge clumps on the inner wall of the aluminum tube 7, and as the sludge accumulates... The increasing amount of sludge will affect the drainage effect of aluminum pipe 7. In heavy rain, rainwater cannot be discharged from aluminum pipe 7 in time. At this time, the controller can be set to start motor 12 periodically. When motor 12 starts, shaft 13 will rotate under the drive of motor 12. At this time, scraper 16 can scrape off the sludge on the inner wall of aluminum pipe 7, thereby improving the drainage effect of aluminum pipe 7. When scraper 16 moves, it will pass through the inclined surface of top block 18, so that slide rod 15 is retracted into connecting rod 14. Then spring 17 will push scraper 16, causing scraper 16 to vibrate, thereby shaking off the impurities on the side of scraper 16 and preventing sludge from remaining and accumulating on scraper 16 and affecting the scraping effect.

[0033] A flexible hollow block 19 is fixedly installed on one side of the scraper 16. A set of piercing cones 20 are fixedly connected to the side of the hollow block 19 away from the scraper 16. When the scraper 16 cleans the sludge, some of the sludge will accumulate on the hollow block 19, and the rest will fall directly from the aluminum tube 7. When the scraper 16 moves, the piercing cones 20 will break the sludge, which will facilitate the subsequent discharge of the sludge from the aluminum tube 7. At the same time, the broken sludge can be better scraped off by the scraper 16. The hollow block 19 will be deformed under the pressure of the piercing cones 20. After the piercing cones 20 have completely passed through the sludge, the hollow block 19 will return to its original shape, thereby throwing away the sludge remaining on the hollow block 19, which will further improve the cleaning effect of the remaining sludge. At the same time, the hollow block 19 will shake, which will also shake off the sludge on the piercing cones 20.

[0034] The scraper 16 has a hollow structure, and the hollow block 19 is connected to the interior of the scraper 16. The hollow block 19 stores water, and a shrinkage hole 21 is opened in the hollow block 19 at the position corresponding to the piercing cone 20. A through water outlet hole is opened in the piercing cone 20. When the hollow block 19 is squeezed and deformed, the shrinkage hole 21 will open. At this time, the water in the hollow block 19 will be sprayed onto the sludge from the water outlet hole of the piercing cone 20 to moisten the sludge, thereby improving the cleaning effect of the scraper 16 on the sludge.

[0035] The top of the scraper 16 is provided with a water inlet groove 22, and a filter screen 23 is fixedly installed on the inner wall of the water inlet groove 22. A sponge block 25 is provided inside the scraper 16, and a sealing block 24 is fixedly connected to the top of the sponge block 25. When it rains, rainwater will be discharged from the aluminum pipe 7. At this time, the rainwater will pass through the scraper 16, so that the rainwater enters the scraper 16 from the water inlet groove 22, thereby achieving the function of automatically collecting and storing rainwater, achieving the effect of saving water resources. At the same time, the filter screen 23 can filter impurities in the water and prevent impurities from entering the scraper 16. As the water level in the scraper 16 rises, the sponge block 25 will float upward. After the water in the scraper 16 is stored to the maximum capacity, the sealing block 24 will seal the water inlet groove 22. Then, when the hollow block 19 deforms, the water in the scraper 16 will be squeezed out onto the sludge.

[0036] A clearing rod 26 is uniformly fixedly connected to the sealing block 24, and a cylinder 27 is fixedly connected to the center of the top surface of the sponge block 25. The filter screen 23 is made of elastic material, and a discharge mechanism is provided inside the scraper 16. During the process of sealing the water inlet tank 22 by the sealing block 24, the clearing rod 26 can clear the mesh of the filter screen 23 to prevent sludge from clogging the mesh of the filter screen 23. Then, as the sealing block 24 continues to rise, the cylinder 27 will push the filter screen 23, causing the filter screen 23 to deform and arch upwards, allowing impurities to slide down to the discharge mechanism for discharge, thereby cleaning and discharging the impurities on the filter screen 23 and preventing the impurities cleared by the clearing rod 26 from remaining on the filter screen 23, thus preventing the mesh of the filter screen 23 from clogging again.

[0037] The discharge mechanism includes a set of guide channels 29, which are formed inside the scraper 16 and communicate with the inlet channel 22. The scraper 16 has a storage tank 30 communicating with the guide channels 29. The guide channels 29 are inclined. The inner wall of the storage tank 30 is slidably connected to a push plate 31. The bottom surface of the push plate 31 is fixedly connected to a fixing rod 32, and the top surface of the push plate 31 is inclined. When the filter screen 23 is arched upward, impurities will slide off the filter screen 23 to both sides, and then enter the storage tank 30 through the guide channels 29, and fall onto the push plate 31. When the sealing block 24 seals the inlet channel 22, the sealing block 24 will push the fixing rod 32, causing the fixing rod 32 to push the push plate 31 out of the storage tank 30. Then the impurities on the push plate 31 will slide onto the top surface of the scraper 16 for discharge, thus automatically discharging the impurities on the filter screen 23.

[0038] Hollow elastic blocks 34 are uniformly fixedly connected to the side of the top block 18 near the hollow block 19. Air holes 35 are uniformly opened on the elastic blocks 34. When the scraper 16 passes the side of the top block 18, it will squeeze the elastic blocks 34. At this time, the gas inside the elastic blocks 34 will be discharged from the air holes 35. The gas will blow onto the hollow block 19, thereby blowing away the impurities on the hollow block 19, thereby further improving the effect of removing impurities from the hollow block 19.

[0039] Example 2

[0040] like Figure 8 As shown in the first embodiment, another embodiment of the present invention is as follows: a vertically arranged guide rod 36 is fixedly connected inside the scraper 16, and the interior of the sponge block 25 is slidably connected to the surface of the guide rod 36; by means of the guide rod 36, the sponge block 25 can move vertically, so that the sealing block 24 can be aligned with the position of the water inlet 22, thus preventing the problem that the sealing block 24 cannot be aligned with the water inlet 22 for sealing.

[0041] Working principle: The aluminum alloy frame beam 1 is tightly connected to the main structure through pre-embedded anchor bolts. The lower deck 3 is connected to the aluminum alloy frame beam 1 using special fasteners 2. Multiple sets of lower deck 3 can be connected by embedded locking with the first buckle 5. Multiple sets of upper deck 4 can be connected by embedded locking with the second buckle 10. The upper deck 4 and lower deck 3 are connected by embedded locking with the third buckle 11, so that the upper deck 4 and lower deck 3 form the entire panel structure system. The aluminum alloy water trough 6 is fixed to the upper and lower deck 3 with core-pulling anchor nails 9. The water trough is connected to the aluminum pipe 7, and the lower part of the aluminum pipe 7 is connected to the PVC pipe 8. The upper deck 4 has drainage holes with a spacing of 20cm-22cm. When it rains, the rainwater falls onto the upper deck 4 through the drainage holes. The rainwater flows down the lower deck 3 into the aluminum alloy water trough 6, and then flows down the aluminum pipe 7 to the roof. The entire drainage process of the floor is a concealed and orderly drainage. Because the helipad surface is made entirely of aluminum, it will not crack or rust, and its aesthetic appearance enhances its service value. Before the embedded locking of the first clip 5, second clip 10, and third clip 11, silicone is injected into the connection seam. This ensures a stronger connection and a tighter connection between decks. The use of silicone and embedded locking at the connection seam prevents rainwater leakage, thus improving the overall drainage and sealing effect. During drainage, the aluminum pipe 7 carries sludge, some of which adheres to it. After rain, this sludge clumps on the inner wall of the aluminum pipe 7, affecting its drainage performance. In heavy rain, rainwater cannot drain from the aluminum pipe 7 in time. To address this, the controller can be programmed to periodically start the motor 12. When the motor 12 starts, the shaft 13 rotates, and the scraper 16 removes the sludge from the inner wall of the aluminum pipe 7. This improves the drainage effect of the aluminum pipe 7. When the scraper 16 moves, it passes over the inclined surface of the top block 18, causing the slide rod 15 to retract into the connecting rod 14. Then, the spring 17 pushes the scraper 16, causing it to vibrate and remove impurities from the side of the scraper 16, preventing sludge from accumulating on the scraper 16 and affecting the scraping effect. When the scraper 16 cleans the sludge, some of the sludge will accumulate on the hollow block 19, while the rest will fall directly from the aluminum pipe 7. When the scraper 16 moves... The piercing cone 20 breaks up the sludge, making it easier for the sludge to be discharged from the aluminum pipe 7. At the same time, the broken sludge can be better scraped off by the scraper 16. The hollow block 19 will deform under the pressure of the piercing cone 20. After the piercing cone 20 has completely passed through the sludge, the hollow block 19 will recover, thereby discarding the sludge remaining on the hollow block 19 and further improving the cleaning effect of the remaining sludge. At the same time, the hollow block 19 will shake, thereby shaking off the sludge on the piercing cone 20.When the hollow block 19 is compressed and deformed, the shrinkage hole 21 opens, and the water inside the hollow block 19 is sprayed onto the sludge from the water outlet of the piercing cone 20, wetting the sludge and thus improving the cleaning effect of the scraper 16 on the sludge. On rainy days, rainwater is discharged from the aluminum pipe 7, passing through the scraper 16 and entering it from the water inlet trough 22, thus automatically collecting and storing rainwater, achieving water conservation. Simultaneously, the filter screen 23 filters impurities from the water, preventing them from entering the scraper 16. As the water level rises, the sponge block 25 floats upwards. After the water in the scraper 16 reaches its maximum capacity, the sealing block 24 seals the inlet tank 22. Then, when the hollow block 19 deforms, the water in the scraper 16 is squeezed out onto the sludge. During the sealing process of the sealing block 24, the unblocking rod 26 can unblock the mesh of the filter screen 23, preventing the sludge from clogging the mesh. Then, as the sealing block 24 continues to rise, the cylinder 27 pushes the filter screen 23, causing it to deform and arch upwards, allowing impurities to slide down into the discharge machine. The impurities on the filter screen 23 are discharged through the drain, thus cleaning and removing them. This prevents the impurities that were cleared by the drain rod 26 from remaining on the filter screen 23 and causing the mesh of the filter screen 23 to become clogged again. When the filter screen 23 is arched upwards, the impurities will slide off the filter screen 23 to both sides, and then enter the storage tank 30 through the guide channel 29. They will then fall onto the push plate 31. When the sealing block 24 seals the water inlet tank 22, the sealing block 24 will push the fixing rod 32, causing the fixing rod 32 to push the push plate 31 out of the storage tank 30. Then the impurities on the push plate 31 will slide onto the scraper. The top surface of plate 16 discharges wastewater, automatically removing impurities from filter screen 23. When scraper 16 passes the side of top block 18, it squeezes elastic block 34, causing gas inside elastic block 34 to escape through air hole 35. This gas blows onto hollow block 19, removing impurities and further improving the removal effect. Guide rod 36 allows sponge block 25 to move vertically, aligning sealing block 24 with water inlet trough 22 and preventing misalignment for sealing.
