Description
Technical Field
[0001] The utility model relates to a rainwater diversion system on the surface of a glass curtain wall, belonging to the technical field of building curtain walls. Background Art
[0002] With the development of society, glass curtain walls are more and more widely used in high-end office buildings, hotels and other buildings, so the penetration rate of existing glass curtain walls is getting higher and higher.
[0003] Most buildings with glass curtain walls are taller. Under the same weather conditions, the ambient temperature of the glass curtain walls is lower. When encountering severe weather conditions such as freezing rain, the freezing rain will quickly condense into ice after it is released from the surface of the glass curtain wall. Under the action of gravity, it will come into contact with the alloy frame at the edge of the curtain wall and accumulate on the frame, eventually covering the entire glass surface with ice. This will reduce the light transmittance of the glass curtain wall and affect the light collection in the room. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a rainwater diversion system for the surface of a glass curtain wall, which solves the problem in the prior art that when encountering severe weather conditions such as freezing rain, the freezing rain will quickly condense into ice after being released from the surface of the glass curtain wall, and will contact and accumulate on the alloy frame at the edge of the curtain wall under the action of gravity, eventually causing the entire glass surface to be covered with an ice layer, which will reduce the light transmittance of the glass curtain wall and affect the indoor light collection.
[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a rainwater diversion system on the surface of a glass curtain wall, comprising a curtain wall frame, a glass wall, a connecting wire, a fixing plate and a heating wire, wherein the edge of the glass wall is embedded and fixed inside the curtain wall frame, a fixing plate is arranged at the connection between one side of the glass wall and the inner side of the curtain wall frame, the fixing plate extends along the edge direction of the glass wall, two ends of the fixing plate are fixedly connected to the inner side of the curtain wall frame, a gap exists between the fixing plate and the glass wall to form a heating space, a drainage channel is formed between a side of the fixing plate facing the inner side of the curtain wall frame and the inner side of the curtain wall frame, the heating wire is arranged on a side of the fixing plate facing the glass wall, the heating wire is electrically connected to one end of the connecting wire, and the other end of the connecting wire extends along the inside of the curtain wall frame to a side of the glass wall away from the fixing plate and extends to the outside of the curtain wall frame.
[0006] By adopting the above technical solution, when normal rain falls on the glass wall, it slides on the glass wall under the action of gravity and finally flows out through the drainage channel, thereby achieving the purpose of diverting and draining ordinary rainwater. When the outdoor temperature is low and freezing rain weather occurs, the freezing rain will quickly condense into ice after falling on the glass wall. During this process, it will slide along the glass wall and accumulate in the heating space. At this time, the heating wire is energized, and the internal ambient temperature of the heating space is increased after the heating wire is heated. At this time, the ice accumulated in the heating space is melted into water by the heat and discharged from the drainage channel, so that the glass curtain wall can effectively cope with freezing rain weather and avoid ice from quickly condensing on the glass wall and affecting the light transmittance of the glass wall.
[0007] The utility model is further configured as follows: a sliding cavity is opened on a side of the heating wire away from the fixed plate, the heating wire is located in the sliding cavity, a heat conducting plate sliding toward the glass wall is arranged in the sliding cavity, the heat conducting plate is fixedly connected to the heating wire, the connecting end of the connecting wire and the heating wire extends into the sliding cavity and is flexibly connected, a plurality of heat conducting blocks are arranged and fixedly arranged on a side of the heat conducting plate facing the glass wall, and the end of the heat conducting block can abut against the glass wall.
[0008] By adopting the above technical solution, after the heating wire is heated, the heat of the heating wire can be transferred to the heat-conducting block through the heat-conducting plate. Since there are multiple heat-conducting blocks and the ends of the heat-conducting blocks can abut against the glass wall, the heat of the heat-conducting block can be directly transferred to the glass wall. Compared with the ambient heat radiation to melt the ice in the heating space, this direct heating method can not only make the ice melt quickly after contacting the heat-conducting block, but also increase the temperature of the glass wall, so that freezing rain will not freeze when it falls on the glass wall, thereby further improving the anti-icing ability of the glass curtain wall in freezing rain weather.
[0009] The utility model is further configured that: the connection between the heat conducting plate and the sliding cavity is sealed and the extension length of the heat conducting block toward the glass wall is less than or equal to the spacing distance between the fixed plate and the glass wall.
[0010] The utility model is further configured as follows: a flip plate is arranged at one end of the fixed plate away from the drainage channel, the flip plate is hingedly arranged with the fixed plate, and the two ends of the flip plate in the extending direction of the fixed plate abut against the inner side of the curtain wall frame for sealing.
[0011] By adopting the above technical solution, after the end of the flip plate away from the hinge is abutted against the glass wall, the flip plate will close the space opening between the fixed plate and the glass wall, and external water or ice cannot enter the heating space. On normal rainy days, rainwater flows directly to the outside of the fixed plate away from the glass wall through the diversion of the flip plate, avoiding the heat conductive block from rusting due to long-term contact with rainwater, thereby improving the service life of the heat conductive block.
[0012] The utility model is further configured as follows: a driving cavity is opened at the connection between the inside of the curtain wall frame and the fixed plate, a rack sliding toward the glass wall is arranged in the driving cavity, one end of the rack passes through the curtain wall frame and is fixedly connected to the heat conduction plate, a driving motor is fixedly installed in the driving cavity, the output end power of the driving motor is connected to a driving gear, the driving gear is meshed with the rack, and the output end of the driving motor passes through the curtain wall frame and is fixedly connected to the hinge shaft of the flip plate.
[0013] By adopting the above technical solution, after the driving motor is started in the forward direction, it drives the driving gear to rotate, thereby driving the rack to slide toward the glass wall. At this time, the glass wall drives the heat conducting plate to slide toward the glass wall and makes the end of the heat conducting block abut against the glass wall. At this time, the driving motor is turned off. During this process, the output end of the driving motor drives the hinge shaft of the flip plate to rotate, thereby causing the flip plate to flip in the direction away from the glass wall. At this time, the ice on the glass wall can melt and shatter, and then be disconnected from the glass wall and blocked by the flip plate, thereby preventing part of the ice from falling from a high altitude and threatening the safety of passers-by, which is beneficial to protecting the personal safety of passers-by. When the driving motor is started in the reverse direction, the flip plate is restored to the abutment state with the glass wall through the reverse action of the above process, and the heat conducting block is disconnected from the glass wall.
[0014] The utility model is further configured such that the inner side surface of the curtain wall frame where the drainage channel is located is inclined from the direction from the glass wall to the fixing plate toward the direction away from the fixing plate.
[0015] By adopting the above technical solution, setting the inner side surface of the curtain wall frame as an inclined surface can make the water in the heating space flow out faster, which is beneficial to the drainage of the glass curtain wall.
[0016] The beneficial effects of the utility model are as follows: when normal rain falls on the glass wall, it slides on the glass wall under the action of gravity and finally flows out through the drainage channel, thereby achieving the purpose of diverting and draining ordinary rainwater; when the outdoor temperature is low and freezing rain weather occurs, the freezing rain will quickly condense into ice after falling on the glass wall, and in the process will slide along the glass wall and accumulate in the heating space, at this time the heating wire is energized, and the heating wire heats up to increase the internal ambient temperature of the heating space, at this time the ice accumulated in the heating space melts into water when heated and is discharged from the drainage channel, thereby enabling the glass curtain wall to effectively cope with freezing rain weather and preventing ice from quickly condensing on the glass wall and affecting the light transmittance of the glass wall.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the following is a brief introduction Figure 1-6 Shown, the utility model is further described.
[0025] like Figure 1 and Figure 4As shown, the rainwater diversion system on the surface of the glass curtain wall includes a curtain wall frame 10, a glass wall 11, a connecting wire 13, a fixing plate 20 and a heating wire 25. The edge of the glass wall 11 is embedded and fixed inside the curtain wall frame 10. A fixing plate 20 is provided at the connection between one side of the glass wall 11 and the inner side of the curtain wall frame 10. The fixing plate 20 extends along the edge direction of the glass wall 11. Both ends of the fixing plate 20 are fixedly connected to the inner side of the curtain wall frame 10. There is a gap between the fixing plate 20 and the glass wall 11 to form a heating space. A drainage channel 22 is formed between a side of the fixing plate 20 facing the inner side of the curtain wall frame 10 and the inner side of the curtain wall frame 10. The inner side of the curtain wall frame 10 where the drainage channel 22 is located is inclined from the direction of the glass wall 11 to the fixing plate 20 in a direction away from the fixing plate 20. Setting the inner side of the curtain wall frame 10 as an inclined surface can make the water in the heating space flow out faster, which is beneficial to the drainage of the glass curtain wall. The heating wire 25 is arranged on the side of the fixed plate 20 facing the glass wall 11, the heating wire 25 is electrically connected to one end of the connecting wire 13, and the other end of the connecting wire 13 extends along the inside of the curtain wall frame 10 to the side of the glass wall 11 away from the fixed plate 20 and extends to the outside of the curtain wall frame 10. A sliding cavity 23 is provided on the side of the heating wire 25 away from the fixed plate 20, the heating wire 25 is located in the sliding cavity 23, a heat conducting plate 24 sliding toward the glass wall 11 is arranged in the sliding cavity 23, the heat conducting plate 24 is fixedly connected to the heating wire 25, the connecting end of the connecting wire 13 and the heating wire 25 extends into the sliding cavity 23 and is flexibly connected, a plurality of heat conducting blocks 26 are arranged and fixedly arranged on the side of the heat conducting plate 24 facing the glass wall 11, and the end of the heat conducting block 26 can abut against the glass wall 11. The connection between the heat conducting plate 24 and the sliding cavity 23 is sealed, and the extension length of the heat conducting block 26 toward the glass wall 11 is less than or equal to the spacing distance between the fixed plate 20 and the glass wall 11.
[0026] like Figure 4 and Figure 5 As shown, a flip plate 21 is provided at one end of the fixed plate 20 away from the drainage channel 22, and the flip plate 21 is hingedly arranged with the fixed plate 20, and the two ends of the flip plate 21 located in the extension direction of the fixed plate 20 are abutted and sealed with the inner side surface of the curtain wall frame 10. The flip plate 21 is hingedly connected to the fixed plate 20 through a hinge shaft, wherein the flip plate 21 is fixed to the hinge shaft, and when the hinge shaft rotates, the flip plate 21 rotates accordingly.
[0027] like Figure 3 and Figure 6As shown, a driving cavity 30 is opened at the connection between the curtain wall frame 10 and the fixed plate 20, one side of the driving cavity 30 is connected to the outside and a detachable sealing cover plate 12 is fixedly arranged at the connection point, a rack 33 sliding toward the glass wall 11 is arranged in the driving cavity 30, one end of the rack 33 passes through the curtain wall frame 10 and is fixedly connected to the heat conducting plate 24, a driving motor 31 is fixedly installed in the driving cavity 30, the output end of the driving motor 31 is connected to the driving gear 32, the driving gear 32 is meshed with the rack 33, and the output end of the driving motor 31 passes through the curtain wall frame 10 and is fixedly connected to the hinge shaft of the flip plate 21.
[0028] When normal rain falls on the glass wall 11, it slides on the glass wall 11 under the action of gravity, and finally flows out through the drainage channel 22, thereby achieving the purpose of diverting and draining ordinary rainwater. When the outdoor temperature is low and there is freezing rain weather, the freezing rain will quickly condense into ice after falling on the glass wall 11. During this process, it will slide along the glass wall 11 and accumulate in the heating space. At this time, the heating wire 25 is energized, and the heating wire 25 heats up to increase the internal ambient temperature of the heating space. At this time, the ice accumulated in the heating space is melted into water by the heat and discharged from the drainage channel 22, so that the glass curtain wall can effectively cope with freezing rain weather and avoid ice from quickly condensing on the glass wall 11 and affecting the light transmittance of the glass wall 11.
[0029] After the heating wire 25 is heated, the heat of the heating wire 25 can be transferred to the heat-conducting block 26 through the heat-conducting plate 24. Since there are multiple heat-conducting blocks 26 and the ends of the heat-conducting blocks 26 can abut against the glass wall 11, the heat of the heat-conducting block 26 can be directly transferred to the glass wall 11. Compared with melting the ice in the heating space by ambient heat radiation, this direct heating method can not only make the ice melt quickly after contacting the heat-conducting block 26, but also increase the temperature of the glass wall 11, so that when freezing rain falls on the glass wall 11, it will not freeze, thereby further improving the anti-icing ability of the glass curtain wall in freezing rain weather.
[0030] After the end of the flip plate 21 away from the hinge is brought into contact with the glass wall 11, the flip plate 21 closes the space opening between the fixed plate 20 and the glass wall 11, and external water or ice cannot enter the heating space. On normal rainy days, rainwater flows directly to the outside of the fixed plate 20 away from the glass wall 11 through the diversion of the flip plate 21, avoiding the heat conductive block 26 from rusting due to long-term contact with rainwater, thereby increasing the service life of the heat conductive block 26.
[0031] After the driving motor 31 is started in the forward direction, it drives the driving gear 32 to rotate, thereby driving the rack 33 to slide toward the glass wall 11. At this time, the glass wall 11 drives the heat conducting plate 24 to slide toward the glass wall 11 and makes the end of the heat conducting block 26 abut against the glass wall 11. At this time, the driving motor 31 is turned off. During this process, the output end of the driving motor 31 drives the hinge shaft of the flip plate 21 to rotate, thereby causing the flip plate 21 to flip in the direction away from the glass wall 11. At this time, the ice on the glass wall 11 can melt and break, and then be disconnected from the glass wall 11 and blocked by the flip plate 21, thereby preventing some ice from falling from a high altitude and threatening the safety of passers-by, which is beneficial to protecting the personal safety of passers-by. When the driving motor 31 is started in the reverse direction, the flip plate 21 is restored to the abutment state with the glass wall 11 through the reverse action of the above process, and the heat conducting block 26 is disconnected from the glass wall 11.
[0032] The above shows and describes the basic principles, main features and advantages of the utility model.
