Abstract
Description
Technical Field
[0001] This utility model relates to the field of skylight drainage structure, specifically a skylight condensation trough drainage structure. Background Technology
[0002] Skylights are widely used in modern architecture, providing ample natural light and enhancing the overall aesthetics of the building. However, during use, skylights are prone to condensation due to temperature and humidity differences between indoors and outdoors. If this condensation is not properly managed, it can have numerous adverse effects on the building structure and the indoor environment.
[0003] Currently, common condensation channel drainage structures for skylights typically place the condensation channel along the lower edge. In this traditional design, condensation drips directly into the channel. However, in daily use, condensation tends to splash during dripping, preventing some from accurately reaching the channel, resulting in low collection efficiency. Excess condensation may also flow freely along the edges of the skylight, seeping into structural gaps. Long-term accumulation can lead to serious problems such as structural corrosion and leaks, threatening the building's safety and lifespan. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a drainage structure for a condensation channel in a skylight.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a condensation trough drainage structure for a skylight, including a keel frame, an outer frame, connectors and a drainage part. The outer frame is fixedly installed on the top of the keel frame, and a sealing strip is embedded at the connection between the two. A skylight panel is embedded and fixedly installed on the top of the outer frame, and the tops of the outer frame and the skylight panel are arranged flush.
[0006] The connector is a steel structure component. One end of the connector is fixedly installed at the bottom end of the keel frame, and the other end of the connector is fixedly connected to a U-shaped condensation groove pipe. Sealing gaskets are provided at the connection points between the connector, the keel frame, and the U-shaped condensation groove pipe. A drainage hole is provided at the bottom of the U-shaped condensation groove pipe.
[0007] The drainage section includes a circular tube frame fixedly installed on the top of the U-shaped condensation trough tube. The top of the circular tube frame has a placement groove. A ball head is set at the center of the internal position of the circular tube frame. Sleeves are symmetrically installed on the outer wall of the ball head. A telescopic rod is inserted into the sleeve. One end of the telescopic rod is connected to a compression spring. The compression spring is located inside the sleeve and its one end is in contact with the outer wall of the ball head. The other end of the telescopic rod is fixedly connected to an arc plate. The arc of the arc plate is the same as the arc of the internal part of the circular tube frame. A silicone pad is embedded in the outer wall of the arc plate. The silicone pad is in contact with the inner wall of the circular tube frame but not connected. A top rod is fixedly connected to the outer wall of the ball head. The center line of the top rod is perpendicular to the center line of the sleeve. A drainage plate is fixedly connected to the top end face of the top rod.
[0008] Specifically, buckles are fixedly installed at both ends of the arc plate, and through holes are provided inside the buckles.
[0009] Specifically, the top rod is a threaded rod structure component. An adjusting nut is installed on the outside of the top rod through a threaded fit. A through-hole column is fixedly installed on the end face of the adjusting nut facing the buckle plate. A wedge block is fixedly installed on the inner wall of the buckle plate, and the outer side of the wedge block is an arc-shaped inclined surface.
[0010] Specifically, the drainage plate has an insertion hole inside, and a positioning bolt is installed in the insertion hole. The upper end face of the drainage plate is close to an extension plate. The extension plate has a strip hole inside, and one end of the positioning bolt passes through the strip hole. A positioning nut is installed at the end of the positioning bolt, and the positioning nut is close to the upper end face of the extension plate.
[0011] Specifically, a V-shaped plate is installed at the bottom of the U-shaped condensation trough pipe, and a round hole is opened at the center of the V-shaped plate. The bottom of the round hole is connected to the drain hole through a straight pipe.
[0012] Specifically, the U-shaped condensation trough tube is equipped with filter plates inside, and the aperture of multiple filter plates gradually decreases from top to bottom, with any filter plate located directly above the V-shaped plate.
[0013] Specifically, all of the filter plates are components made of alumina ceramic.
[0014] The beneficial effects of this utility model are:
[0015] This utility model describes a condensation channel drainage structure for skylights. When the installer pushes a top rod, the ball joint connected to the bottom of the rod rotates within a circular tube frame. One end of the guide plate connected to the top of the rod moves towards the edge of the skylight panel until it touches the panel and stops moving. This completes the installation of the guide section. This guide section is suitable for different types of skylight panels. Condensate then slides along the guide plate into the U-shaped condensation channel. Compared to traditional drip collection methods, this method allows the guide section to be adjusted according to the actual angle of the skylight panel, enabling more accurate flow of condensate into the U-shaped condensation channel. This reduces splashing and spillage during the flow of condensate on the skylight panel, ensuring that almost all condensate is collected in the U-shaped condensation channel, improving collection efficiency. It also prevents condensate from dripping onto building components below the skylight, preventing long-term contact that could lead to rust and corrosion. Furthermore, it keeps condensate away from building components, extending their lifespan and maintaining the integrity of the building structure.
[0016] The present invention discloses a condensation channel drainage structure for a skylight. After the angle of the drainage plate is adjusted, the adjusting nut can be turned by a wrench. The adjusting nut moves along the top rod towards the ball head. During the movement of the adjusting nut, the through-hole column is simultaneously driven to contact the arc-shaped inclined surface of the wedge block and apply a squeezing force to it. Under the action of this squeezing force, the two buckle plates are pushed to move. Then, the buckle plates drive the silicone pads on the outer walls of the two arc plates to be tightly pressed against the inner wall of the circular tube frame, further increasing the connection stability of the drainage part, so that it will not shake during daily use and ensuring its drainage effect.

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.
[0025] See Figure 1-4 The present invention discloses a condensation channel drainage structure for a skylight, comprising a keel frame 1, an outer frame 2, a connector 4, and a drainage part 6. The outer frame 2 is fixedly installed on the top of the keel frame 1, and a sealing strip is embedded at the connection between the two to increase the sealing between them and prevent water leakage. A skylight panel 3 is embedded and fixedly installed on the top of the outer frame 2. The tops of the outer frame 2 and the skylight panel 3 are flush and there is no height difference. That is, when condensation occurs on the skylight panel 3 due to temperature difference, the condensate can slide down along the top of the skylight panel 3 under its own gravity.
[0026] The connector 4 is a steel structure component. One end of the connector 4 is fixedly installed at the bottom end of the keel frame 1, and the other end of the connector 4 is fixedly connected to a U-shaped condensation groove pipe 5. The U-shaped condensation groove pipe 5 is used to collect the condensate that slides down from the top of the light-transmitting panel 3.
[0027] Sealing gaskets are provided at the connection points of connector 4 with keel frame 1 and U-shaped condensation groove pipe 5 to increase the connection stability of connector 4. Drainage hole 51 is provided at the bottom of U-shaped condensation groove pipe 5. Drainage hole 51 is connected to outdoor main drain pipe, that is, condensate water entering U-shaped condensation groove pipe 5 can enter the main drain pipe and be discharged along drainage hole 51.
[0028] The drainage section 6 includes a circular tube frame 61 fixedly installed on the top of the U-shaped condensation groove pipe 5, and the circular tube frame 61 can be used as follows: Figure 2The structure shown is composed of a support plate and a round tube. The top of the round tube frame 61 is provided with a placement groove 611. The placement groove 611 is a type of arc groove, and the coverage perimeter of the placement groove 611 is less than half the perimeter of the round tube area of the round tube frame 61.
[0029] A ball head 62 is located at the center of the inner part of the circular tube frame 61. A sleeve 63 is symmetrically installed on the outer wall of the ball head 62. A telescopic rod 64 is inserted into the sleeve 63. One end of the telescopic rod 64 is connected to a compression spring 65. The compression spring 65 is located inside the sleeve 63 and one end of it is in contact with the outer wall of the ball head 62. The other end of the telescopic rod 64 is fixedly connected to an arc plate 66. The telescopic rod 64 can move in and out along the inside of the sleeve 63. During the telescopic movement, it can apply a compressive force to the compression spring 65 to compress and deform it. During installation, the two arc plates 66 are aligned with the placement groove 611 and pushed inward. Under the action of the compressive force, the two arc plates 66 contract in the same direction (that is, the telescopic rod 64 moves towards the inside of the sleeve 63 and compresses the compression spring 65). When the two arc plates 66 are completely inside the circular tube frame 61, the rebound force generated when the compression spring 65 is compressed pushes the two arc plates 66 towards the inner wall of the circular tube frame 61.
[0030] The arc of the arc plate 66 is equal to the internal arc of the circular tube frame 61. A silicone pad 661 is embedded in the outer wall of the arc plate 66, and the silicone pad 661 contacts but is not connected to the inner wall of the circular tube frame 61. As the arc plate 66 moves toward the inner wall of the circular tube frame 61, it causes the silicone pad 661 to press against the inner wall of the circular tube frame 61. At this time, the position of the ball head 62 is positioned under the action of friction. A push rod 67 is fixedly connected to the outer wall of the ball head 62, and the center line of the push rod 67 is perpendicular to the center line of the sleeve 63. A drain plate 68 is fixedly connected to the top end face of the push rod 67. During installation, the construction personnel push the push rod 67, and the ball head 62 connected to the bottom of the push rod 67 rotates inside the circular tube frame 61. The top of the push rod 67 is connected to the drain plate 68. One end of the drainage plate 68 moves towards the edge of the skylight 3 until it touches against the edge of the skylight 3 and stops moving. At this point, the installation of the drainage section 6 is complete. Condensate can then slide down the drainage plate 68 into the U-shaped condensation channel 5. Compared to the traditional drip collection method, the drainage section can be adjusted according to the actual angle of the skylight 3, allowing the condensate to flow more accurately into the U-shaped condensation channel 5. This reduces splashing and spillage of condensate as it flows on the skylight 3, ensuring that almost all condensate is collected in the U-shaped condensation channel 5, improving collection efficiency. It also prevents condensate from dripping onto the building components below the skylight 3, preventing long-term contact that could lead to rust and corrosion. The adjustable drainage section 6 keeps condensate away from these components, extending their lifespan and maintaining the integrity of the building structure.
[0031] See Figure 2The two ends of the arc plate 66 are fixedly installed with buckle plates 69, and the buckle plates 69 have through holes 691 inside. The through holes 691 provide installation positions for components such as sleeves 63 and telescopic rods 64. During installation, the construction personnel can press the buckle plates 69 with their hands to cause the two arc plates 66 to retract, which makes it easy to insert the two arc plates 66 into the round tube frame 61.
[0032] In another embodiment, see Figures 1-4 The top rod 67 is a threaded rod structure component. An adjusting nut 671 is installed on the outside of the top rod 67 via a threaded connection. A through-hole column 672 is fixedly installed on the end face of the adjusting nut 671 facing the buckle plate 69. A wedge block 673 is fixedly installed on the inner wall of the buckle plate 69, and the outer side of the wedge block 673 is an arc-shaped inclined surface. In specific operation, after the angle of the diversion plate 68 is adjusted, the adjusting nut 671 can be rotated by a wrench. The adjusting nut 671 moves along the top rod 67 towards the ball head 62. During the movement of the adjusting nut 671, the through-hole column 672 is simultaneously driven to contact the arc-shaped inclined surface of the wedge block 673 and apply a squeezing force to it. Under the action of this squeezing force, the two buckle plates 69 are pushed to move. Then, the buckle plates 69 drive the silicone pads 661 on the outer walls of the two arc plates 66 to be tightly squeezed against the inner wall of the round tube frame 61, further increasing the connection stability of the diversion part 6, so that it will not shake during daily use and ensure its diversion effect.
[0033] In another embodiment, see Figures 1-4 The diversion plate 68 has an insertion hole 683 inside, and a positioning bolt 684 is installed in the insertion hole 683. The upper end face of the diversion plate 68 is close to the extension plate 681. The extension plate 681 has a strip hole 682 inside, and one end of the positioning bolt 684 passes through the strip hole 682. A positioning nut 685 is installed at the end of the positioning bolt 684, and the positioning nut 685 is close to the upper end face of the extension plate 681. By loosening the positioning nut 685 with a wrench, the extension plate 681 can be pushed to slide along the upper end face of the diversion plate 68. After adjusting to the specified position, tightening the positioning nut 685 can complete the combined length adjustment of the diversion plate 68 and the extension plate 681, further increasing its application range.
[0034] Meanwhile, a flexible pad is embedded in the end face of the extension plate 681 that abuts against the light-transmitting plate 3. The flexible pad is a component made of non-absorbent material. When the extension plate 681 moves toward the end of the light-transmitting plate 3, the flexible pad first contacts the light-transmitting plate 3 and deforms inward. At this time, the gap between the extension plate 681 and the light-transmitting plate 3 will be filled by the flexible pad, so that no residual condensate will appear during drainage.
[0035] like Figure 4As shown, a V-shaped plate 52 is installed at the bottom of the U-shaped condensation channel 5. A circular hole is opened at the center of the V-shaped plate 52. The bottom of the circular hole is connected to the drain hole 51 through a straight pipe. There is a height difference between the two ends of the V-shaped plate 52 and the center position. When condensate enters the U-shaped condensation channel 5, it will flow into the drain hole 51 along the V-shaped plate 52, reducing the residual condensate inside the U-shaped condensation channel 5.
[0036] In another embodiment, participants Figure 1 As shown, the U-shaped condensation trough pipe 5 is equipped with filter plates 53. The aperture of multiple filter plates 53 gradually decreases from top to bottom, and any filter plate 53 is located directly above the V-shaped plate 52. Through multi-stage filtration, large particles of debris can be filtered onto the filter plates 53, avoiding blockage of the drain hole 51.
[0037] Specifically, all of the filter plates 53 are made of alumina ceramic, which is a hydrophilic material. The filter plates 53 made of this material allow water to spread quickly on their surface and form a water film. This helps the condensate to pass through the filter screen 53 more quickly, reduces the residence time of the water on the filter screen 53, improves the filtration efficiency, and allows the condensate to flow more smoothly to the V-shaped plate 52, avoiding water accumulation or backflow caused by poor water flow.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
