Description

Technical Field

[0001] This application relates to the technical field of water supply and drainage, and particularly to a rainwater hopper for flexible socket drainage pipes. Background Art

[0002] A rainwater hopper is a drainage device provided at the eaves for discharging roof rainwater. The rainwater hopper generally includes a rainwater hopper body with a top opening and an installation riser provided at the bottom of the rainwater hopper body. A drain pipe is also provided at the bottom of the installation riser. The rainwater on the roof flows into the rainwater hopper body and the installation riser in sequence, and is discharged through the drain pipe.

[0003] Currently, the installation riser and the drain pipe are usually connected by fixing methods such as bolts and nuts. This connection method has the following problems: 1. During the use of the installation riser and the drain pipe, affected by the external environmental temperature, there is a phenomenon of thermal expansion and contraction. However, due to the fixed connection between the installation riser and the drain pipe, telescopic compensation cannot be achieved, resulting in bending or breaking of the installation riser and the drain pipe due to thermal expansion and contraction; 2. When installing or disassembling the installation riser and the drain pipe, installation tools are required, making both installation and disassembly relatively troublesome; and in some positions with small operating spaces, the installation difficulty is further increased. Therefore, there is an urgent need for a rainwater hopper that can prevent pipe fittings from being damaged due to thermal expansion and contraction and is simple to install to solve the above problems.

[0004] The information disclosed in this background art section is only for enhancing the understanding of the background art of the present disclosure, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0005] In view of the above problems, a rainwater hopper for flexible socket drainage pipes is provided. This rainwater hopper can not only avoid damage to the rainwater hopper and the drain pipe due to thermal expansion and contraction, but also has a good sealing effect, and at the same time, both installation and disassembly are relatively simple.

[0006] Specifically, this application provides a rainwater hopper for flexible socket drainage pipes, which includes a rainwater hopper body with a top opening, an installation inner cylinder and an installation outer cylinder that are coaxially arranged at the bottom of the rainwater hopper body; the inner edge surface of the installation inner cylinder is communicated with the inner edge surface of the rainwater hopper body; a slot for inserting a drain pipe is formed between the installation inner cylinder and the installation outer cylinder; a first annular groove is provided on the inner wall of the installation outer cylinder, and a first sealing ring is embedded in the first annular groove; a second annular groove is provided on the outer wall of the installation inner cylinder, and a second sealing ring is embedded in the second annular groove.

[0007] Optionally, the wall thickness of the first sealing ring at the end close to the rainwater bucket body is greater than the wall thickness of the first sealing ring at the end far from the rainwater bucket body, so as to form a first guiding inclined surface on the inner wall of the first sealing ring; the wall thickness of the second sealing ring at the end close to the rainwater bucket body is greater than the wall thickness of the first sealing ring at the end far from the rainwater bucket body, so as to form a second guiding inclined surface on the outer wall of the second sealing ring.

[0008] Optionally, the distance between the first annular groove and the bottom of the rainwater bucket body is equal to the distance between the second annular groove and the bottom of the rainwater bucket body.

[0009] Optionally, the rainwater bucket further includes an anti-blocking sieve tube sleeved on the top opening of the installation inner cylinder.

[0010] Optionally, the anti-blocking sieve tube includes a sieve tube body and an annular support plate arranged at the outer edge of the top of the sieve tube body; water outlet holes are arranged on the side wall and the bottom wall of the sieve tube body.

[0011] Optionally, the outer diameter of the outer side wall of the anti-blocking sieve tube is smaller than the inner diameter of the inner wall of the installation inner cylinder.

[0012] Optionally, the bottom of the rainwater bucket body is in a tapered shape.

[0013] In the rainwater bucket of the flexible socket drainage pipe of the present application, since the drainage pipe and the rainwater bucket are flexibly connected through the first sealing ring and the second sealing ring, when affected by the external environmental temperature and thermal expansion and contraction occurs, telescopic compensation can be realized, avoiding bending or breaking of the rainwater bucket and the drainage pipe due to thermal expansion and contraction. At the same time, the two sealing rings achieve double sealing, making the sealing effect better and preventing leakage. Moreover, the drainage pipe is directly inserted into the slot of the rainwater bucket for connection without the use of installation tools, making the installation and disassembly relatively simple. Even in a position with a small operating space, the installation connection can be realized.

The "first", "second", etc. involved in the present application are used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" involved in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0022] Figure 1 This is a schematic structural view of the rainwater bucket in the embodiment of the present application, as Figure 1 shown, and with reference to Figures 2 to 5 this, the embodiment of the present application provides a rainwater bucket 100 for a flexible socket drainage pipe, which includes a rainwater bucket body 110 with an open top, an installation inner cylinder 130 and an installation outer cylinder 120 that are arranged at the bottom of the rainwater bucket body 110 and are coaxially arranged. The inner edge surface of the installation inner cylinder 130 is communicated with the inner edge surface of the rainwater bucket body 110. A slot 140 for inserting a drainage pipe is formed between the installation inner cylinder 130 and the installation outer cylinder 120. A first annular groove 121 is provided on the inner wall of the installation outer cylinder 120, and a first sealing ring 150 is embedded in the first annular groove 121. A second annular groove 131 is provided on the outer wall of the installation inner cylinder 130, and a second sealing ring 160 is embedded in the second annular groove 131.

[0023] In the rain gutter 100 of the flexible spigot-and-socket drainage pipe of the embodiment of the present application, the drain pipe is inserted into the slot 140 of the rain gutter from the bottom of the rain gutter and forms a sealed connection with the first sealing ring 150 and the second sealing ring 160. The rain gutter of the present application, because the drain pipe and the rain gutter are flexibly connected via the first sealing ring 150 and the second sealing ring 160, can achieve expansion and contraction compensation when affected by the external ambient temperature and thermal expansion and contraction occur, preventing the rain gutter and the drain pipe from bending or breaking due to thermal expansion and contraction. At the same time, the two sealing rings achieve a double seal, which improves the sealing effect and prevents leakage. Moreover, the drain pipe is directly inserted into the slot 140 of the rain gutter to achieve connection, without the need for installation tools, making installation and removal relatively simple, and can be installed and connected even in locations with limited operating space.

[0024] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the wall thickness of the first sealing ring 150 at the end close to the rain gutter body 110 is greater than the wall thickness at the end away from the rain gutter body 110, thereby forming a first guide slope 151 on the inner wall of the first sealing ring 150. The wall thickness of the second sealing ring 160 at the end close to the rain gutter body 110 is greater than the wall thickness at the end away from the rain gutter body 110, thereby forming a second guide slope 161 on the outer wall of the second sealing ring 160.

[0025] In the embodiment of the present application, the first guide bevel 151 is provided on the first sealing ring 150 and the second guide bevel 161 is provided on the second sealing ring 160, which makes it easier for the drain pipe to be inserted into the slot 140 of the rain gutter. Of course, the first sealing ring 150 and the second sealing ring 160 can also be provided with curved surfaces.

[0026] In some embodiments of the present application, Figures 2 to 4 As shown, the distance between the first annular groove 121 and the bottom of the rain gutter body 110 is equal to the distance between the second annular groove 131 and the bottom of the rain gutter body 110. In other words, the heights of the first annular groove 121 and the second annular groove 131 are equal, and thus the installation heights of the first sealing ring 150 and the second sealing ring 160 are also equal. When the drain pipe is inserted into the slot 140, the inner and outer walls of the drain pipe are simultaneously in contact with and squeezed by the first sealing ring 150 and the second sealing ring 160, so that the force is relatively uniform. After the drain pipe is inserted, the first sealing ring 150 and the second sealing ring 160 are at the same height to achieve sealing and fixing of the drain pipe, so that the force on the drain pipe is uniform and the installation is relatively secure.

[0027] In some embodiments of the present application, Figure 2As shown, the rainwater inlet 100 further includes a clogging prevention sieve tube 170 sleeved on the top opening of the installation inner cylinder 130. Those skilled in the art know that long-term scouring of buildings by rainwater can cause small objects such as concrete, putty, sand and gravel on the roof to fall off, and sundries such as fallen leaves will also fall on the roof. When the existing rainwater inlets are in use, small objects such as fallen concrete, putty, sand and gravel and fallen leaves will enter the rainwater inlet and the drain pipe along with the rainwater, causing blockages in the rainwater inlet and the drain pipe. In the embodiment of the present application, due to the provision of the clogging prevention sieve tube 170, small objects such as concrete, putty, sand and gravel and fallen leaves can be prevented from entering the inner installation cylinder and the drain pipe of the rainwater inlet, and thus blockages in the installation inner cylinder 130 and the drain pipe can be prevented. When the clogging prevention sieve tube 170 is filled with clogging substances, the clogging prevention sieve tube 170 can be taken out, the clogging substances can be poured out, and then the clogging prevention sieve tube 170 can be reinstalled to complete.

[0028] In some embodiments of the present application, as Figure 5 shown, the clogging prevention sieve tube 170 includes a sieve tube body 171 and an annular support plate 172 provided at the outer edge of the top of the sieve tube body 171. Water outlet holes 173 are provided at the side wall and the bottom wall of the sieve tube body 171.

[0029] In the embodiment of the present application, the sieve tube body 171 is inserted into the installation inner cylinder 130, and the annular support plate 172 is supported at the top opening of the installation inner cylinder 130. The sieve tube body 171 can hold sundries such as concrete, putty, sand and gravel and fallen leaves, and rainwater can be discharged through the water outlet holes 173.

[0030] In some embodiments of the present application, as Figure 1 shown, the outer diameter of the side wall of the clogging prevention sieve tube 170 is smaller than the inner diameter of the inner wall of the installation inner cylinder 130. In the embodiment of the present application, such a setting enables rainwater to be discharged through the water outlet holes 173 on the side wall of the clogging prevention sieve tube 170, preventing the water outlet holes 173 on the side wall of the clogging prevention sieve tube 170 from being blocked by the inner wall of the installation inner cylinder 130.

[0031] In some embodiments of the present application, as Figure 1 、 Figure 2 and Figure 4 shown, the rainwater inlet body 110 includes a water storage cylinder 111 for storing rainwater and a connecting cylinder 112 communicating with the bottom of the water storage cylinder 111. From the top to the bottom of the connecting cylinder 112, it is tapered, and the bottom of the connecting cylinder 112 communicates with the top of the installation inner cylinder 130.

[0032] In the embodiments of the present application, the water storage cylinder 111 can store rainwater when there is too much rain. The rainwater in the water storage cylinder 111 enters the installation inner cylinder 130 through the connecting cylinder 112 and is then discharged through the drain pipe. Since the connecting cylinder 112 is tapered, on the one hand, it is used to connect the water storage cylinder 111 and the installation inner cylinder 130 with different cross-sectional dimensions, and on the other hand, it can converge the rainwater, so that the rainwater entering the water storage cylinder 111 can flow out as soon as possible.

[0033] In some embodiments of the present application, the shape of the water storage cylinder 111 can be a prism or a cylinder. At least one side surface of the prism is an arc surface. The opening at the top of the water storage cylinder 111 can be flared to facilitate rainwater collection.

[0034] Although some preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of its application concept. Thus, if these modifications and variations to the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these changes and modifications.
