Description

TECHNICAL FIELD

[0001] The present application relates to the field of building waterproofing equipment, in particular to a roof primary-secondary downspout device. BACKGROUND

[0002] Roof downspouts are used in architectural design for effective drainage and protection of building structures from water damage. The main forms of roof downspouts include straight pipe downspouts, elbow pipe downspouts, side-in downspouts, and siphon downspouts.

[0003] Straight pipe downspouts are the most common type, usually consisting of a straight pipe that directs roof drainage directly to the ground or drainage system. This design is simple and direct, suitable for general roof drainage needs, but may have problems with splashing or overflow in heavy rain or strong wind weather.

[0004] Elbow pipe downspouts, on the other hand, are designed with a curved pipe to make the water flow more smoothly, reducing the likelihood of splashing. This design is often used in situations where water flow needs to be discharged along the wall or edge of the building.

[0005] Side-in downspouts introduce water flow from the side of the roof, suitable for some special-shaped or designed buildings, such as terraces, balconies, etc. This design makes the downspout not damage the appearance of the building, while effectively guiding the water flow to the designated location.

[0006] Siphon downspouts use the principle of siphon, through the pressure difference in the pipe to introduce water flow into the pipe and discharge, without external energy driving. This design is suitable for situations that require long-distance drainage or have high drainage requirements, with the characteristics of energy saving and environmental protection.

[0007] According to the related technology in the above, the inventor believes that the existing downspout forms, whether side discharge, straight pipe, siphon, etc., are prone to blockage due to foreign matter. Once blocked, it will not drain well, and drainage problems will easily cause leakage. Roof water cannot be drained smoothly, which is an important factor causing leakage. CONTENT OF THE UTILITY MODEL

[0008] In order to improve the drainage capacity of the downspout, reduce the situation that the downspout is blocked and cannot effectively drain, and thus reduce the problem of roof leakage, the present application provides a roof primary-secondary downspout device.

[0009] The roof primary-secondary downspout device provided by the present application adopts the following technical solution:

[0010] A roof primary-secondary downspout device, comprising a main downspout, a side downspout arranged on one side of the main downspout, and a connecting assembly for relative communication between the main downspout and the side downspout. The height of the inlet end of the side downspout is higher than the height of the inlet end of the main downspout.

[0011] By adopting the technical scheme, the auxiliary drainage can be performed through the side downspout, the drainage amount of the accumulated water is increased, the height difference is arranged between the main downspout and the side downspout, the risk that the main downspout and the side downspout are blocked at the same time is effectively reduced, the main downspout at the low position starts to drain when the main downspout is blocked, the occurrence of the accumulated water is prevented, the risk of roof leakage is reduced, the drainage capacity of the downspout is improved, the situation that the downspout is blocked and cannot effectively drain is reduced, and the problem that the roof leaks is reduced.

[0012] Optionally, the connecting assembly comprises a main drainage pipe arranged vertically at the bottom end of the main downspout, and a side drainage pipe arranged at the bottom end of the side downspout, wherein the main drainage pipe and the side drainage pipe are relatively communicated.

[0013] Optionally, the side drainage pipe comprises a rigid portion and an extension portion, the rigid portion is fixedly connected with the main drainage pipe, and the extension portion is located on one side of the rigid portion close to the side downspout.

[0014] By adopting the technical scheme, the extension portion is arranged, and the length of the extension portion can be adjusted according to the situation, so that the extension portion will not be broken due to the change of the structure and settlement.

[0015] Optionally, the end of the extension portion extends into the inside of the rigid portion, and the outer side of the extension portion is sealingly connected with the inner side of the rigid portion.

[0016] Optionally, a first indicator lamp is fixedly connected to the main drainage pipe, the detection end of the first indicator lamp is located in the main drainage pipe, the display end of the first indicator lamp is located outside the main drainage pipe, a second indicator lamp is fixedly connected to the side drainage pipe, the detection end of the second indicator lamp is located in the side drainage pipe, the display end of the second indicator lamp is located outside the side drainage pipe, and the detection end of the first indicator lamp is higher than the connection position of the main drainage pipe and the side drainage pipe.

[0017] By adopting the technical scheme, when the accumulated water in the main drainage pipe flows through the detection end of the first indicator lamp, the display end of the first indicator lamp is bright, and when the accumulated water in the side drainage pipe flows through the detection end of the second indicator lamp, the display end of the second indicator lamp is bright, so that the work of regularly maintaining the roof can be solved, the risk that the downspout is blocked can be reduced, the difficulty and risk of checking and maintaining the roof are reduced, unnecessary maintenance work is reduced, and unnecessary safety hazards are reduced.

[0018] Optionally, the pipe diameter of the main drain pipe is larger than the pipe diameter of the side drain pipe.

[0019] By using the above technical solution, the side drain pipe serves as an auxiliary drainage function of the main drain pipe. When the main drain pipe can independently complete the drainage task, drainage operation is performed through the main drain pipe. When the drainage capacity of the main drain pipe is insufficient to complete the drainage task or the main drain pipe is blocked, the side drain pipe performs auxiliary drainage task.

[0020] Optionally, when the installation surface heights of the main downspout and the side downspout are the same, a raised platform is arranged at the inlet of the side downspout, and the height of the side away from the side downspout is higher than the height of the inlet end of the main downspout.

[0021] By using the above technical solution, when the installation surface heights of the main downspout and the side downspout are the same, the raised platform can form a liquid level difference for the side downspout. When the discharge capacity of the main downspout is insufficient or the main downspout is blocked, the liquid level gradually rises. When the height of the liquid level is higher than the height of the raised platform, the liquid flows from the top end of the raised platform into the inside of the side downspout for discharge.

[0022] Optionally, the side away from the side downspout of the raised platform is higher than the side close to the side downspout of the raised platform, and the side close to the side downspout of the raised platform is flush with the side downspout.

[0023] Optionally, the main downspout and the side downspout are spaced apart along the transverse direction, and the spacing is in the range of 150-200 mm.

[0024] Optionally, the height difference between the main downspout and the side downspout along the height direction is in the range of 100-150 mm.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. By relatively arranging the main downspout and the side downspout, auxiliary drainage can be performed through the side downspout, the discharge capacity of the accumulated water is increased, and the main downspout and the side downspout are arranged with a height difference, which can effectively reduce the risk of the main downspout and the side downspout being blocked at the same time. Once the main downspout at the lower position is blocked, the side downspout at the higher position starts to drain water, preventing the occurrence of accumulated water and reducing the risk of roof leakage. The drainage capacity of the downspout is improved, the situation that the downspout is blocked and cannot effectively drain water is reduced, and the problem of roof leakage is further reduced.

[0027] 2. When water accumulates inside the main drain pipe and flows through the detection end of the first indicator light, the display end of the first indicator light will light up. When water accumulates inside the side drain pipe and flows through the detection end of the second indicator light, the display end of the second indicator light will light up. This can solve the problem of the roof requiring regular maintenance. Once the first and second indicator lights go out, it is necessary to send someone to the roof to clear and troubleshoot. This can reduce the risk of the drain outlet being blocked. For some non-accessible roofs, it is difficult and risky to go up to the roof for inspection and maintenance. This system can reduce unnecessary maintenance work and reduce unnecessary safety hazards. Attached Figure Description

[0031] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0033] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0034] This application discloses a roof drain device with a male and female drain outlet. (Refer to...) Figure 1 , Figure 2 A roof drain system includes a main drain 1 and a side drain 2 located on one side of the main drain 1. The inlet end of the main drain 1 is located above the mounting surface, and the inlet end of the side drain 2 is also located above the mounting surface. Water accumulated on the mounting surface can be drained through the main drain 1 and the side drain 2. The side drain 2 is used for auxiliary drainage when the main drain 1 has insufficient drainage capacity or is blocked.

[0035] In some embodiments, when the main downspout 1 and the side downspout 2 are installed at a position close to the edge of the parapet, the height at the installation position of the side downspout 2 is higher than the height at the installation position of the main downspout 1, so that the height of the inlet end of the side downspout 2 is higher than the height of the inlet end of the main downspout 1. The height difference between the inlet end of the side downspout 2 and the inlet end of the main downspout 1 can effectively reduce the risk of the main downspout 1 and the side downspout 2 being blocked at the same time. Once the main downspout 1 at the lower position is blocked, the side downspout 2 at the relatively high position starts to drain, preventing the occurrence of water accumulation and reducing the risk of roof leakage. The height difference between the inlet end of the main downspout 1 and the inlet end of the side downspout 2 is in the range of 100-150 mm.

[0036] In some embodiments, when the main downspout 1 and the side downspout 2 are installed at a position close to the edge of the parapet, the height at the installation position of the side downspout 2 is higher than the height at the installation position of the main downspout 1, so that the height of the inlet end of the side downspout 2 is higher than the height of the inlet end of the main downspout 1. The height difference between the inlet end of the side downspout 2 and the inlet end of the main downspout 1 can effectively reduce the risk of the main downspout 1 and the side downspout 2 being blocked at the same time. Once the main downspout 1 at the lower position is blocked, the side downspout 2 at the relatively high position starts to drain, preventing the occurrence of water accumulation and reducing the risk of roof leakage. The height difference between the inlet end of the main downspout 1 and the inlet end of the side downspout 2 is in the range of 100-150 mm.

[0037] The distance between the adjacent main downspout 1 and the side downspout 2 along the transverse direction is in the range of 150-200 mm.

[0038] A main drain pipe 11 is vertically arranged at the bottom end of the main downspout 1, the inside of the main drain pipe 11 is relatively communicated with the inside of the main downspout 1, and the accumulated water on the installation surface enters the inside of the main drain pipe 11 through the main downspout 1 for drainage.

[0039] A side drain pipe 21 is arranged at the bottom end of the side downspout 2, the side drain pipe 21 is arranged obliquely, and the side drain pipe 21 is gradually arranged obliquely towards the side close to the main drain pipe 11 along the height direction from top to bottom, the inside of the side drain pipe 21 is relatively communicated with the inside of the side downspout 2. The side drain pipe 21 includes an elastic part 211 close to the side of the side downspout 2 and a rigid part 212 close to the side of the main drain pipe 11, the rigid part 212 is fixedly connected with the main drain pipe 11, and the rigid part 212 is relatively communicated with the inside of the main drain pipe 11.

[0040] The end of the telescopic part 211 extends into the interior of the hard part 212, and the telescopic part 211 is sealed and fixed between the outer side wall of the interior end of the hard part 212 and the inner side wall of the hard part 212 relative to the telescopic part 211 by filling sealant. The sealant has certain elasticity and strength to resist the gravity of water flow, and has beneficial antioxidant properties and oil stain resistance, and has high reliability. The accumulated water on the installation surface can enter the interior of the side drain pipe 21 through the side water outlet 2, pass through the side drain pipe 21, enter the interior of the main drain pipe 11, and be discharged.

[0041] The telescopic part 211 is made of a telescopic pipe material, and the material can be selected from a soft pvc material. The advantage is that it will not be broken due to the change in structure settlement. If replacement is required, the replacement difficulty is relatively lower.

[0042] The main drain pipe 11 undertakes the main drainage task, and the side drain pipe 21 undertakes the auxiliary drainage task, so the pipe diameter of the main drain pipe 11 is greater than that of the side drain pipe 21.

[0043] The first indicator light 12 is fixedly connected to the side wall of the main drain pipe 11. In some embodiments, the first indicator light 12 is an inductive indicator light, and the inductive indicator light is of an inductive component direct current type. The first indicator light 12 is located above the connection position of the main drain pipe 11 and the measurement drain pipe 21, the detection end of the first indicator light 12 is located in the interior of the main drain pipe 11, and the display end of the first indicator light 12 is located on the outside of the main drain pipe 11. When the liquid in the interior of the main drain pipe 11 passes through the detection end of the first indicator light 12, the display end of the first indicator light 12 is lit.

[0044] The second indicator light 22 is fixedly connected to the side wall of the measurement drain pipe 21. In some embodiments, the second indicator light 22 is an inductive indicator light, and the inductive indicator light is of an inductive component direct current type. The detection end of the second indicator light 22 is located in the interior of the measurement drain pipe 21, and the display end of the second indicator light 22 is located on the outside of the measurement drain pipe 21. When the liquid in the interior of the measurement drain pipe 21 passes through the detection end of the second indicator light 22, the display end of the second indicator light 22 is lit.

[0045] When the first indicator light 12 and the second indicator light 22 are installed, slot processing can be performed at the schematic position according to the size of the first indicator light 12 and the second indicator light 22, and the first indicator light 12 and the second indicator light 22 are respectively embedded in the main drain pipe 11 and the measurement drain pipe 21, and the structure glue is used for sealing treatment around them.

[0046] A first indicator light 12 and a second indicator light 22 are installed at the main drain pipe 11 and the secondary drain pipe 21, respectively. This solves the problem of regular roof maintenance. If either indicator light 12 or the second indicator light 22 goes out, personnel must be sent to the roof for unblocking and inspection, reducing the risk of blocked drain outlets. For some inaccessible roofs, roof inspection and maintenance are difficult and risky. This system can reduce unnecessary maintenance work and lower unnecessary safety hazards.
