Description

Technical Field

[0001] This utility model relates to the field of roof drainage gutter technology, specifically a building antifreeze drainage gutter. Background Technology

[0002] Drainage gutters are important auxiliary components of buildings and an essential part of the roof drainage system. Their primary function is to collect rainwater or snowmelt from the roof and direct it into the downpipes. The cross-sectional dimensions of the drainage gutters are closely related to the rainfall and roof catchment area of ​​the building's location. Under normal circumstances, a well-designed drainage gutter, as part of the roof drainage system, can smoothly drain rainwater from the roof. However, in cold and frigid climates, where snowfall is frequent in winter, if snow cannot melt and drain from the roof in time, ice and snow blocks will accumulate and clog the gutters. Melted snowmelt from the roof cannot drain properly and will accumulate in the gutters, potentially causing roof leaks. Furthermore, the ice and snow blocking the downpipes can cause frost heave, leading to damage and affecting the normal use of the building.

[0003] In extremely cold and frigid regions, the current technology for frost protection of building gutters mainly employs electric heat tracing. Electric heat tracing converts electrical energy into heat energy. The current passes through a heating element, generating heat that is conducted to the gutter surface, melting the snow. The main advantages are as follows: First, compared to traditional methods such as manual snow removal or applying de-icing agents, electric heat tracing can provide a continuous and stable supply of heat, quickly melting the snow in the gutters and ensuring unobstructed drainage. Second, there is no concern about the corrosion and pollution caused by de-icing agents to the gutters, roofs, or the surrounding environment. It also eliminates the safety hazards of open flames, making it safe and reliable.

[0004] However, electric heat tracing also has the following disadvantages: First, from the perspective of energy saving, electric heat tracing tape has a large starting current and has variable power characteristics, making it difficult to accurately control heat consumption power, which is not conducive to energy saving; second, due to the material, the service life of electric heat tracing tape is relatively short and it needs to be replaced regularly, which increases construction costs. Utility Model Content

[0005] The purpose of this utility model is to provide a building anti-freezing drainage gutter that can block blocky ice and snow, reduce the blockage of roof drainage channels by blocky ice and snow, accelerate the melting of snow in the gutter by setting cavity in the side wall of the gutter, and promote the melting of snow in the gutter by using heat conduction pipes instead of electric heat tracing.

[0006] To achieve the aforementioned technical effects, this utility model provides a building anti-freezing drainage gutter, comprising a gutter consisting of a base plate and two side walls forming a U-shaped cross-section. The area between the two side walls and above the base plate forms a drainage channel. Multiple drainage risers are connected to the base plate, arranged linearly and evenly along the length of the gutter. A barrier net and a barrier net support are connected within the drainage channel. A support pipe II is located at the upper center of the barrier net support. Two barrier net supports are provided, fixedly connected to the front and rear ends of the gutter along its length. The barrier net includes a support pipe I and a filter screen with a cross-sectional shape of [missing information]. The system has two arc-shaped filters, which are fixedly connected to the left and right sides of support pipe I. The two filters are evenly distributed around the axis of support pipe I. A shaft is rotatably inserted into the support pipe II of both barrier net supports. The two ends of the shaft are rotatably inserted into the two support pipes II, and the outer diameter of the shaft is smaller than the inner diameter of the support pipe II. The barrier net is located between the two barrier net supports. Support pipe I is rotatably sleeved on the shaft, and the inner diameter of support pipe I is larger than the outer diameter of the shaft. The arc-shaped inner walls of both filters face the bottom plate of the gutter. The barrier net is located above the bottom plate of the gutter. There is a gap between the lower end of both filters and the bottom plate of the gutter, and there is a gap between the outer end of both filters and the two side walls of the gutter.

[0007] Furthermore, both ends of the shaft are provided with external threads. The two external threads extend out of the front and rear ends of the support tube I, respectively. After extending out of the front and rear ends of the support tube I, the two external threads are rotatably inserted into the two support tubes II. Each of the two external threads is connected with a locking nut. The two locking nuts are respectively abutted against the front and rear ends of the support tube I. There is a gap between the two locking nuts and the two support tubes II.

[0008] Furthermore, the two external threaded portions extend out of the two support tubes II respectively, and each external threaded portion extending out of the support tube II is connected to two anti-loosening nuts. The two anti-loosening nuts abut against each other, and there is a gap between the anti-loosening nut closer to the support tube II and the support tube II.

[0009] Furthermore, each of the two sidewalls of the gutter has a sidewall cavity, which extends through the sidewall of the gutter along its length, and both ends of the sidewall cavity are open.

[0010] Furthermore, it includes a heat pipe assembly, which includes a main heat pipe, heat pipe branches, and a buried pipe. The bottom surfaces of the cavities on both sides of the gutter are connected to heat pipe branches. The lower ends of the two heat pipe branches are fixedly connected to the top surface of the main heat pipe. The two heat pipe branches and one main heat pipe form a "Y" shape. The two heat pipe branches and one main heat pipe constitute a group of surface heat pipes. Multiple groups of surface heat pipes are linearly and evenly distributed along the length of the gutter. Multiple groups of surface heat pipes are interspersed with multiple drainage risers. The buried pipe is buried below ground level. The lower ends of the main heat pipes of the multiple groups of surface heat pipes are all connected to the buried pipe.

[0011] Furthermore, the burial depth of the buried pipe is greater than or equal to the maximum freezing depth of the ground.

[0012] Furthermore, the barrier net support is composed of two triangular frames, with the support tube II fixedly connected between the two triangular frames. The two triangular frames are symmetrical about the axis of the support tube II, and a triangular cavity is formed between the two triangular frames at the lower end of the support tube II. Each triangular frame has a triangular cavity inside.

[0013] Furthermore, the materials for the gutter, the barrier mesh, the barrier mesh support, the shaft, and the heat pipe assembly are all made of 304 stainless steel.

[0014] Furthermore, both the locking nut and the anti-loosening nut are A2-70 austenitic stainless steel hexagonal nuts.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a barrier net to directly block chunks of ice and snow on the roof, preventing them from sliding into the gutter. The two arc-shaped inner walls of the barrier net face the bottom of the gutter, and the two filter screens form a cover shape. The barrier net is rotatably connected to two barrier net supports via a shaft, allowing it to rotate around the shaft. When the chunks of ice and snow blocked above the barrier net melt, the rotation of the barrier net facilitates the falling of smaller chunks of ice and snow into the drainage ditch. The barrier net supports and the barrier net can be disassembled and reassembled as needed.

[0017] The heat pipe assembly can transfer heat from the soil into the sidewall cavity, thereby promoting the melting of snow in the drainage ditch.

[0018] This invention effectively blocks blocky ice and snow on roofs, creating ventilation cavities in the gutter sidewalls to accelerate snow melting. The heat-conducting pipe assembly directs heat from the soil to the gutter sidewalls, further promoting snow melting within the gutter. This invention does not alter existing gutter installation techniques and methods, simplifying construction. It consumes no electricity, fully utilizing ambient temperature and soil heat below the frost line, making it energy-efficient and environmentally friendly. It is stable and reliable, preventing problems such as pipe rupture due to ice and snow blockage or roof leaks. Attached Figure Description

[0032] like Figures 1-12 As shown, this utility model discloses a building anti-freezing drainage gutter, which includes a gutter 1. The gutter 1 consists of a base plate and two side walls forming a U-shaped space. The area between the two side walls and above the base plate of the gutter 1 is a drainage channel 102. A drainage riser 103 is connected to the base plate of the gutter 1. Multiple drainage risers 103 are provided and are linearly and evenly distributed along the length of the gutter 1. A barrier net 2 and a barrier net support 3 are connected inside the drainage channel 102. A support pipe II 301 is provided at the upper center of the barrier net support 3. There are two barrier net supports 3. 3. The barrier net 2 is fixedly connected to the front and rear ends of the gutter 1 along its length. The barrier net 2 includes a support pipe I 201 and a filter screen 202. The filter screen 202 has an arc-shaped cross-section. Two filter screens 202 are provided, fixedly connected to the left and right sides of the support pipe I 201 respectively. The two filter screens 202 are evenly distributed around the axis of the support pipe I 201. A shaft 4 is rotatably inserted into the support pipe II 301 of both barrier net supports 3. The two ends of the shaft 4 are rotatably inserted into the two support pipe II 301 respectively. The outer diameter of the shaft 4 is smaller than the inner diameter of the support pipe II 301. The partition net 2 is positioned between two barrier net supports 3. The support pipe I 201 is rotatably sleeved on the shaft 4. The inner diameter of the support pipe I 201 is larger than the outer diameter of the shaft 4. The arc-shaped inner walls of both filter nets 202 face the bottom plate of the gutter 1. The barrier net 2 is positioned above the bottom plate of the gutter 1. Gaps are provided between the lower ends of both filter nets 202 and the bottom plate of the gutter 1, and gaps are also provided between the outer ends of both filter nets 202 and the two side walls of the gutter 1. Both ends of the shaft 4 are provided with external threads 401, which extend from the front and rear ends of the support pipe I 201 respectively. The front and rear ends are rotatably inserted into the two support tubes II 301. Each of the two external threaded parts 401 is connected to a locking nut 5. The two locking nuts 5 are respectively abutted at the front and rear ends of the support tube I 201. There is a gap between the two locking nuts 5 and the two support tubes II 301. The two external threaded parts 401 extend out of the two support tubes II 301 respectively. Each external threaded part 401 extending out of the support tube II 301 is connected to two anti-loosening nuts 6. The two anti-loosening nuts 6 abut against each other. There is a gap between the anti-loosening nut 6 closer to the support tube II 301 and the support tube II 301.

[0033] This utility model uses a barrier net 2 to directly block blocky ice and snow on the roof, preventing the blocky ice and snow from sliding into the gutter 1. The barrier net 2 is formed by two arc-shaped inner walls facing two filter screens 202 on the bottom plate of the gutter 1, forming a cover shape. The barrier net 2 is rotatably connected to two barrier net supports 3 via a shaft 4. The barrier net 2 can rotate around the shaft 4. When the blocky ice and snow blocked above the barrier net 2 melts into small pieces, the rotation of the barrier net 2 facilitates the small pieces of ice and snow falling into the drainage trough 102. The barrier net supports 3 and the barrier net 2 can be disassembled and assembled as needed.

[0034] Depending on the building, the required length of gutter 1 varies. Sometimes, multiple sections of gutter 1 need to be spliced ​​together along the length direction for use. When multiple sections of gutter 1 are spliced ​​together along the length direction, two barrier net supports 3, one shaft rod 4, and a set of barrier nets 2 are generally installed in each section of gutter 1. In addition, each section of gutter 1 is equipped with a drainage riser 103. With this configuration, even if barrier nets 2 are installed at the connection between multiple sections of gutter 1, it will not cause blockage of gutter 1. There are various ways to splice and fix multiple sections of gutter 1 along the length direction, usually welding, which are all common technical means and will not be listed one by one.

[0035] The locking nut 5 can fix the barrier net 2 to the shaft 4, so that the barrier net 2 can rotate with the shaft 4, while ensuring that the barrier net 2 will not be displaced in the axial direction of the shaft 4.

[0036] The gaps between the two locking nuts 5 and the two support tubes II 301 are to prevent interference between the locking nuts 5 and the support tubes II 301, which would affect the rotation of the barrier net 2 and the shaft 4.

[0037] The anti-loosening nut 6 is provided to prevent the shaft 4 from falling out of the support tube II 301. Two anti-loosening nuts 6 are connected to each external thread part 401 to lock each other and prevent the anti-loosening nuts 6 from falling out. The anti-loosening nut 6 near the support tube II 301 is provided with a gap to prevent the anti-loosening nut 6 from interfering with the support tube II 301 and affecting the rotation of the shaft 4.

[0038] In addition to using the locking nut 5 and anti-loosening nut 6 for positioning and ensuring rotation in this embodiment, the locking nut 5 and anti-loosening nut 6 can also be replaced with cotter pins and corresponding pin holes can be provided on the shaft 4, or the locking nut 5 and anti-loosening nut 6 can be replaced with retaining rings and corresponding retaining ring grooves can be provided on the shaft 4 for use.

[0039] The barrier net support 3 consists of two triangular frames. The support tube II 301 is fixedly connected between the two triangular frames. The two triangular frames are symmetrical about the axis of the support tube II 301. A triangular cavity is formed between the two triangular frames at the lower end of the support tube II 301. Each triangular frame has a triangular cavity inside.

[0040] Due to the presence of multiple triangular cavities, the installation of the barrier net bracket 3 does not affect the smooth passage of rainwater in the drainage channel 102.

[0041] Both sides of the gutter 1 have a sidewall cavity 101 inside. The sidewall cavity 101 extends through the sidewall of the gutter 1 along its length and is open at both ends.

[0042] The side wall cavity 101 forms a ventilation cavity, which helps to promote heat exchange between the gutter 1 and the environment when the ambient temperature rises, and can accelerate the melting of snow in the drainage trough 102; preferably, the inner wall of the gutter should be coated with a black anti-corrosion coating, which is conducive to absorbing heat when exposed to sunlight.

[0043] This utility model includes a heat-conducting pipe assembly 7, which includes a heat-conducting main pipe 701, heat-conducting branch pipes 702, and a buried pipe 703. The bottom surfaces of the two side wall cavities 101 of the gutter 1 are connected to the heat-conducting branch pipes 702. The lower ends of the two heat-conducting branch pipes 702 are fixedly connected to the top surface of the heat-conducting main pipe 701. The two heat-conducting branch pipes 702 and one heat-conducting main pipe 701 form a "Y" shape. The two heat-conducting branch pipes 702 and one heat-conducting main pipe 701 constitute a group of ground-level heat-conducting pipes. The ground-level heat-conducting pipes are arranged in multiple linearly evenly along the length of the gutter 1. The multiple groups of ground-level heat-conducting pipes are interspersed with multiple drainage risers 103. The buried pipe 703 is buried below the ground. The lower ends of the heat-conducting main pipes 701 of the multiple groups of ground-level heat-conducting pipes are all connected to the buried pipe 703. The burial depth of the buried pipe 703 is greater than or equal to the maximum freezing depth of the ground.

[0044] The burial depth of the buried pipe 703 is greater than or equal to the maximum freezing depth of the ground. Therefore, the heat pipe assembly 7 can introduce heat from the soil into the side wall cavity 101, thereby promoting the melting of snow in the drainage ditch 102.

[0045] Because this utility model is used outdoors for a long time and is frequently in contact with rain or snow, in order to prevent corrosion, the materials of the gutter 1, barrier net 2, barrier net support 3, shaft 4 and heat conduction pipe assembly 7 are all 304 stainless steel; the locking nut 5 and the anti-loosening nut 6 are both A2-70 austenitic stainless steel hexagonal nuts.

[0046] like Figure 11 and Figure 12This utility model does not change the existing technology for roof gutter installation. The support and installation of gutter 1 are the same as the existing conventional methods. This utility model can be installed at the edge of the eaves or in the middle of the roof. When installed in the middle of the roof, it is usually an internal rainwater pipe. The riser can be set in conjunction with the frame column to avoid affecting the usable space inside the building. Both installation positions make reasonable use of the roof fascia board and eaves purlins, and use gutter brackets, building frames, etc. as supporting components to install the gutter between the building roof panel and the building steel frame.
