Description

Technical Field

[0001] The utility model relates to the technical field of building drainage, in particular to an assembled drainage structure at the bottom of an eave. Background Technique

[0002] Building drainage is an important part of building design. The building drainage system can discharge rainwater in a directional manner, enabling rainwater to be discharged into the drainage ditch as expected. However, due to defects in the drainage structure design of some existing buildings, the rainwater discharge capacity is insufficient. Usually, in this case, a gutter drainage trough is installed to drain rainwater. The gutter drainage trough generally includes a drainage trough body and a drain pipe. The drainage trough body receives the rainwater sliding down from the roof, enabling the rainwater to be discharged from the drain pipe.

[0003] A filter screen is usually arranged at the pipe orifice of the drain pipe of the existing gutter drainage trough to prevent the drain pipe from being blocked by impurities. However, during actual use, since various impurities are likely to accumulate on the roof, after being washed by rainwater, the impurities will flow to the filter screen along with the rainwater, resulting in the blockage of the drain pipe orifice and the inability of rainwater to be smoothly discharged from the drain pipe. Therefore, an assembled drainage structure at the bottom of an eave is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] Based on the above description, the utility model provides an assembled drainage structure at the bottom of an eave to solve the problem that the pipe orifice of the drain pipe is easily blocked by impurities such as leaves and feathers.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: an assembled drainage structure at the bottom of an eave, including: a drainage trough, which includes a communication hole, a drain pipe, and a water outlet hole;

[0006] An installation frame, which is arranged outside the drainage trough;

[0007] A backflush pipe and a spray head, the spray head is arranged at the inner bottom of the drainage trough, one end of the backflush pipe is communicated with the water outlet hole, and the other end of the backflush pipe extends into the communication hole and is communicated with the spray head;

[0008] A filter plate, which is arranged inside the drainage trough and is located below the water outlet hole.

[0009] Based on the above technical solution, the utility model can be further improved as follows.

[0010] Further, the drainage trough includes a trough body, the drain pipe and the water outlet hole are respectively arranged on both side walls of the trough body, and the drain pipe is communicated with the trough body.

[0011] Further, the communication hole is arranged on the bottom wall of the trough body.

[0012] Furthermore, the backwashing pipe includes a U-shaped pipe, and a first flange is arranged on the outer surface of the U-shaped pipe. The first flange is connected to the drainage groove by screws and nuts.

[0013] Furthermore, the spray head includes a hollow head, and a second flange is arranged on the outer surface of the hollow head. The second flange is connected to both the drainage groove and the first flange by screws and nuts simultaneously.

[0014] Furthermore, a spray orifice is arranged on the upper surface of the hollow head, and the spray orifice is communicated with the hollow head.

[0015] Furthermore, placing strips are arranged on both side walls inside the tank body. The filter plate includes a plate body, and mounting holes and filtering holes are arranged on the upper surface of the plate body. Screws penetrate through the mounting holes and are threadedly connected to the placing strips, and the spray orifice faces the filtering holes.

[0016] Furthermore, the mounting frame includes a U-shaped frame, a fixing frame is arranged on one side of the U-shaped frame, a reinforcing plate is arranged between the fixing frame and the U-shaped frame, and the U-shaped frame is arranged outside the tank body.

[0017] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0018] 1. By arranging components such as a drainage groove and a filter plate in the present utility model, rainwater can only flow to the pipe orifice of the drain pipe after being filtered by the filter plate, and the filter plate plays a preliminary blocking effect. Moreover, the filter plate is arranged along the length direction of the drainage groove, and impurities can be laid flat on the filter plate, avoiding the situation where all impurities accumulate at the pipe orifice. Secondly, if the filter plate is blocked and the drainage capacity becomes weak, the setting of the backwashing pipe can prevent impurities from rising with the water level when the water level in the drainage groove is too high, overflowing from the drainage groove and finally falling from the roof, causing the phenomenon of high-altitude throwing or spilling.

[0019] 2. Among them, the setting of the backwashing pipe and the spray head can also achieve the effect of rainwater backwashing. When the filtering holes of the filter plate are blocked by impurities such as leaves, the drainage capacity decreases. If the rainfall is greater than the drainage capacity after being blocked, the water level in the drainage groove will rise. The rising rainwater flows into the backwashing pipe, and under the action of the communicating vessel principle, the rainwater sprays out from the spray head. After the sprayed water flow contacts impurities such as leaves, it is possible to separate the leaves and other impurities from the filtering holes of the filter plate under the action of the impact force, thereby playing a certain role in dredging the filtering holes.

[0034] Please refer to Figure 1 、 Figure 4 and Figure 5 , an assembled eaves bottom drainage structure, comprising:

[0035] A drainage trough 1, which includes a communication hole 13, a drain pipe 14 and a water outlet hole 15.

[0036] Specifically, the drainage trough 1 includes a trough body 11. Drain pipes 14 and water outlet holes 15 are respectively arranged on both side walls of the outer surface of the trough body 11. The drain pipe 14 is communicated with the inside of the trough body 11. Placing strips 12 are arranged on both side walls inside the trough body 11. A filter plate 5 is installed on the placing strip 12. A communication hole 13 is arranged on the bottom wall of the trough body 11. The drain pipe 14 is located below the filter plate 5, and the water outlet hole 15 is located above the filter plate 5.

[0037] Among them, as Figure 1 、 Figure 2 and Figure 9 shown, the filter plate 5 is arranged inside the drainage trough 1 and is located below the water outlet hole 15. The filter plate 5 includes a plate body 51. Mounting holes 52 and filtering holes 53 are arranged on the upper surface of the plate body 51. Screws pass through the mounting holes 52 and are threadedly connected with the placing strip 12.

[0038] As Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown, a backwashing pipe 3 and a nozzle 4. The nozzle 4 is arranged at the bottom wall of the drainage trough 1. One end of the backwashing pipe 3 is communicated with the water outlet hole 15, and the other end of the backwashing pipe 3 extends into the communication hole 13 and is connected with the nozzle 4. The outer wall of the backwashing pipe 3 and the inner wall of the communication hole 13 are sealed.

[0039] Specifically, the backwashing pipe 3 includes a U-shaped pipe 31. A first flange 32 is arranged on the outer surface of the U-shaped pipe 31. The first flange 32 is hermetically connected with the drainage trough 1 by screws and nuts.

[0040] Based on the above structure, the filter holes 53 on the surface of the filter plate 5 play a role in initially filtering rainwater, separating the rainwater from impurities such as leaves, and preventing the impurities from clogging the drain pipe 14. The arrangement of the placement strip 12 enables the filter plate 5 to be detachably installed inside the drainage groove 1 by screws. The drain pipe 14 allows the rainwater to be discharged normally. The setting of the water outlet hole 15 enables the rainwater after the water level rises to flow into the backwash pipe 3, and then flow back to the bottom inside the drainage groove 1 through the backwash pipe 3, and finally be discharged through the drain pipe 14, which can prevent the impurities from rising with the water level when the water level in the drainage groove 1 is too high, overflowing from the drainage groove 1, and finally falling from the roof, causing the phenomenon of high-altitude throwing or spilling.

[0041] In this embodiment, the spray head 4 can include a hollow head 41. A second flange 42 is provided on the outer surface of the hollow head 41. The second flange 42 is hermetically connected to both the drainage groove 1 and the first flange 32 by screws and nuts. A spray orifice 43 is provided on the upper surface of the hollow head 41. The spray orifice 43 is communicated with the hollow head 41, and the spray orifice 43 is disposed below the filter plate 5.

[0042] When the filter holes of the filter plate 5 are blocked, the drainage capacity of the filter plate 5 is weakened. When the drainage capacity is less than the rainfall, the water level above the filter plate 5 rises. At this time, the water flow flows from the backwash pipe 3 into the spray head 4. And because the space below the filter plate 5 is not filled with rainwater, under the action of the communicating vessel principle, the water flow will spray out from the spray orifice 43. The sprayed water flow will impact impurities such as leaves, which may cause the impurities such as leaves to separate from the filter plate 5, thereby playing a certain role in dredging the filter plate 5.

[0043] In this embodiment, as Figure 1 、 Figure 2 and Figure 6 shown, the mounting bracket 2 is provided outside the drainage groove 1 and is used to support the main structure of the drainage groove 1.

[0044] Specifically, the mounting bracket 2 includes a U-shaped bracket 21. A fixing bracket 22 is provided on one side of the U-shaped bracket 21. A reinforcing plate 23 is provided between the fixing bracket 22 and the U-shaped bracket 21. The U-shaped bracket 21 is disposed outside the trough body 11 and is used to lift the trough body 11. Four screw holes are provided on the side wall of the fixing bracket 22. The fixing bracket 22 can be detachably installed on the wall surface by bolts, that is, the mounting bracket 2 can be detachably installed on the wall surface by bolts. In this way, the drainage groove 1 and the mounting bracket 2 can be pre-assembled and then installed on the wall surface by bolts, avoiding long-term high-altitude operation of the staff.

[0045] When the drainage structure provided in this embodiment is actually used, the drainage groove 1 is detachably installed on the wall surface through the mounting bracket 2. When it rains, the rainwater slides along the roof into the inside of the drainage groove 1, and the rainwater is discharged from the drain pipe 14 after being filtered by the filter plate 5.

[0046] When impurities such as leaves and feathers fall into the inside of the drainage trough 1, if the impurities exactly cover the filter holes 53, the filter holes 53 will be blocked. At this time, the amount of rainwater entering the inside of the drainage trough 1 through the filter holes 53 decreases, which in turn causes the water storage amount above the filter plate 5 to increase. When the water level rises, it can enter the inside of the backwash pipe 3 from the water outlet hole 15. Under the action of the communicating vessel principle, the water flow entering the inside of the backwash pipe 3 can be ejected from the nozzle 4. The ejected water flow impacts the impurities on the filter holes 53, and then the impurities are separated from the filter holes 53 under the action of this impact force, that is, a certain effect of dredging the filter holes 53 is achieved. Compared with the traditional gutter drainage trough, this drainage structure can fully prevent the drainage trough 1 from being blocked and overflowing.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
