Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of expansion joint connectors for drainage ditches, and particularly to stainless steel expansion joint connectors for drainage ditches. Background Technology
[0002] As an important component of metal roofs, stainless steel gutters play a crucial role in the waterproofing and drainage system of the entire metal roof. In order to prevent the stainless steel gutters from cracking and deforming due to deformation caused by temperature stress, stainless steel gutters are equipped with expansion joints every 20 to 30 meters.
[0003] For example, the patent entitled "A Gutter Connection and Overflow Prevention Structure for Metal Roofs" (patent application number: CN201521066296.3) discloses a gutter connection and overflow prevention structure for metal roofs. By setting stainless steel round pipes between the two gutters, the water in the two gutters can be drained, thereby playing a good protective role for the entire roof and effectively extending its service life. However, in actual use, there is only a single set of stainless steel round pipes, and the drainage effect is generally average when the water volume is large.
[0004] Therefore, it is necessary to propose a stainless steel expansion joint connector for drainage ditches to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a stainless steel drainage ditch expansion joint connector to solve the problem that in actual use, a single set of stainless steel round pipes has a mediocre drainage effect when the water volume is large.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a stainless steel water ditch expansion joint connector, comprising a first ditch body and a second ditch body, wherein the first ditch body and the second ditch body are collinearly distributed, and a first conveying pipe and a second conveying pipe are respectively connected to both sides of the first ditch body, wherein the first conveying pipe is located in the lower half of the side wall of the first ditch body, and the second conveying pipe is located in the upper half of the side wall of the first ditch body.
[0007] The second trench is connected to a first pair of pipes and a second pair of pipes on both sides. The first pair of pipes and the second pair of pipes are both located in the lower half of the sidewall of the first trench, and the first pair of pipes and the second pair of pipes are distributed relative to each other.
[0008] The first delivery pipe is connected to the first connecting pipe via a first connecting component, and the second delivery pipe is connected to the second connecting pipe via a second connecting component.
[0009] Preferably, the first connecting component includes a first circular tube, one end of which is connected to a first conveying tube, and the other end of which is connected to a first connecting tube.
[0010] Preferably, the second connecting component includes a second circular tube, one end of which is connected to a second conveying tube, and the other end of which is connected to a second connecting tube.
[0011] Preferably, an overlapping plate is fixedly connected to the top of the first groove near the second groove, and an overlapping edge is fixedly connected to the top of the second groove near the first groove. The overlapping plate overlaps the overlapping edge, and a limiting folding edge is fixedly connected to the end of the overlapping plate away from the first groove.
[0012] Preferably, vertical plates are fixedly connected to both sides of the overlapping plate.
[0013] Preferably, a first limiting baffle is fixedly connected to both sides of the top of the second groove.
[0014] Preferably, a second limiting baffle is fixedly connected to both sides of the top of the first groove.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1.

[0023] This utility model provides, for example Figures 1-4 The stainless steel expansion joint connector shown includes a first channel body 1 and a second channel body 2. The first channel body 1 and the second channel body 2 are collinearly distributed, and both the first channel body 1 and the second channel body 2 are installed at a certain angle. Water flows from the first channel body 1 to the second channel body 2 and continues to flow downward. The first channel body 1 and the second channel body 2 are both made of stainless steel.
[0024] An overlapping plate 13 is fixedly connected to the top of the first channel body 1 near the second channel body 2, and an overlapping edge 11 is fixedly connected to the top of the second channel body 2 near the first channel body 1. The overlapping plate 13 overlaps the overlapping edge 11, and a limiting folding edge 9 is fixedly connected to the end of the overlapping plate 13 away from the first channel body 1. Vertical plates 14 are fixedly connected to both sides of the overlapping plate 13, and the vertical plates 14 are fixedly connected to the first channel body 1 to improve the strength of the overlapping plate 13. The overlapping plate 13, the limiting folding edge 9, and the vertical plates 14 are provided to both protect against rain and allow for expansion and contraction. When the first channel body 1 and the second channel body 2 slide relative to each other, the overlapping plate 13 slides on the overlapping edge 11.
[0025] Both sides of the top of the second groove body 2 are fixedly connected to the first limiting baffle 10 to improve the strength of the second groove body 2.
[0026] The first groove body 1 has two fixedly connected second limiting baffles 12 on both sides of its top, which improves the strength of the first groove body 1.
[0027] The first channel 1 is connected to the first conveying pipe 3 and the second conveying pipe 4 on both sides respectively. The first conveying pipe 3 is located in the lower half of the side wall of the first channel 1, and the second conveying pipe 4 is located in the upper half of the side wall of the first channel 1. The second channel 2 is connected to the first pair of connecting pipes 5 and the second pair of connecting pipes 6 on both sides respectively. The first pair of connecting pipes 5 and the second pair of connecting pipes 6 are both located in the lower half of the side wall of the first channel 1, and the first pair of connecting pipes 5 and the second pair of connecting pipes 6 are distributed opposite to each other.
[0028] The first conveying pipe 3 is connected to the first connecting pipe 5 through the first connecting component. The first connecting component includes a first circular pipe 7, one end of which is connected to the first conveying pipe 3, and the other end of which is connected to the first connecting pipe 5.
[0029] In actual use, clamps or similar components can be used to connect the first round pipe 7 with the first conveying pipe 3 and the first connecting pipe 5.
[0030] The second conveying pipe 4 is connected to the second connecting pipe 6 through the second connecting component. The second connecting component includes a second circular pipe 8, one end of which is connected to the second conveying pipe 4, and the other end of which is connected to the second connecting pipe 6.
[0031] In actual use, clamps or similar components can be used to connect the second round pipe 8 with the second conveying pipe 4 and the second connecting pipe 6.
[0032] Both the first round tube 7 and the second round tube 8 can be corrugated pipes, which are telescopic.
[0033] The first conveying pipe 3 is located in the lower half of the side wall of the first trench 1. When the water volume is small, the water can be guided by the first conveying pipe 3, the first circular pipe 7 and the first connecting pipe 5. At the same time, since the water volume is small, when the water flows into the second trench 2 from the first connecting pipe 5, it will not cause an impact on the side of the second trench 2 near the second connecting pipe 6.
[0034] When the water volume is large, the water can be diverted by the first conveying pipe 3, the first circular pipe 7 and the first connecting pipe 5, and the water can also be diverted by the second conveying pipe 4, the second circular pipe 8 and the second connecting pipe 6.
[0035] Since the first conveying pipe 3 is located in the lower half of the side wall of the first trench 1, and the second conveying pipe 4 is located in the upper half of the side wall of the first trench 1, the connection point between the second conveying pipe 4 and the first trench 1 is higher than the connection point between the first conveying pipe 3 and the first trench 1. That is, when the water volume is small, only the first conveying pipe 3, the first circular pipe 7, and the first connecting pipe 5 (low-level pipe) are used for water diversion, while the second conveying pipe 4, the second circular pipe 8, and the second connecting pipe 6 (high-level pipe) do not need to participate in water diversion. At this time, the second conveying pipe 4, the second circular pipe 8, and the second connecting pipe 6 can avoid wear due to the impact of water. When the water volume is large, the second conveying pipe 4, the second circular pipe 8, and the second connecting pipe 6 can transport water normally. Compared with the method of directly setting two sets of first conveying pipes 3, first circular pipes 7, and first connecting pipes 5, it is more flexible to use.
[0036] In addition, when the water volume is large, when the water flows into the second channel 2 from the first pair of connectors 5, it is easy to cause an impact on the side of the second channel 2 near the second pair of connectors 6. At this time, water also flows into the second channel 2 from the second pair of connectors 6. Since the first pair of connectors 5 and the second pair of connectors 6 are relatively distributed, the impact forces on both sides consume each other, reducing the impact force on the second channel 2.
[0037] This utility model forms a low-level pipeline and a high-level pipeline by setting up a first connecting component and a second connecting component, and adapts to the water volume to ensure the drainage effect. At the same time, it can reduce the wear of the second conveying pipe 4 and other structures, and the impact forces on both sides are mutually consumed when the water volume is large, thus improving the efficiency of the stainless steel water ditch expansion joint connector.
