Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a novel rainwater pipe interface structure. Background Technology

[0002] Rainwater pipes are drainage facilities used to collect and transport rainwater to discharge points, and the interface structure of rainwater pipes is a key part of connecting pipe sections to ensure that two adjacent sets of rainwater pipes can be stably connected.

[0003] Existing rainwater pipe interface structures mostly use single flange connections or simple plug-in structures, lacking positioning and reinforcement designs. Under the long-term impact of water flow, the interfaces are prone to loosening and misalignment, leading to water leakage. At the same time, existing rainwater pipe interfaces usually do not have dedicated filtration and unblocking structures. Mud, sand, fallen leaves and other impurities carried by rainwater can easily accumulate at the interfaces or pipe bends, causing blockages. Cleaning requires disassembling a large number of pipes, which is time-consuming and labor-intensive, and it is difficult to observe the blockage status in real time.

[0004] Therefore, this utility model proposes a novel rainwater pipe interface structure. Utility Model Content

[0005] Based on this, in order to overcome the problems of insufficient stability and ease of installation of common new rainwater pipe interface structures, as well as the difficulty of pipe unblocking and weak impurity filtration capacity.

[0006] The technical solution of this utility model is as follows: a novel rainwater pipe interface structure, including an inlet pipe, a drain pipe, and a Y-shaped pipe. The inlet pipe is located on the side of the drain pipe. Two sets of Y-shaped pipes are provided. The first set of Y-shaped pipes is installed on the side of the pipe body at the drain end of the inlet pipe, and the second set of Y-shaped pipes is installed on the side of the pipe body at the inlet end of the drain pipe. Control valves are installed inside the two branch pipes of the first set of Y-shaped pipes. The valve stem rotation ends of the two sets of control valves are located outside the Y-shaped pipes.

[0007] An interface plug-in assembly is installed between the water inlet pipe and the Y-shaped pipe, and an auxiliary unblocking assembly is installed at the middle position of the two sets of Y-shaped pipes.

[0008] Preferably, the interface plug-in assembly includes a positioning outer ring, a positioning inner ring, a limiting T-shaped strip, and a limiting T-shaped groove. A flange is fixedly installed on the outer wall of the water inlet pipe at the water inlet end. A positioning outer ring is fixedly installed on the outer wall of the water inlet pipe at the water outlet end. A positioning inner ring is fixedly installed on the outer wall of the first group of Y-shaped pipes at the water inlet end, and the positioning inner ring is slidably installed inside the positioning outer ring. Four sets of limiting T-shaped strips are fixedly installed circumferentially on the outer side wall of the positioning inner ring at the annular surface. Four sets of limiting T-shaped grooves for the insertion and installation of the limiting T-shaped strips are correspondingly opened on the inner side wall of the positioning outer ring at the annular surface.

[0009] Preferably, the outer wall of the positioning ring located on the annular surface has four sets of positioning threaded grooves that are circumferentially open, and the positioning threaded grooves are in communication with the internal space of the limiting T-shaped groove. The outer wall of the limiting T-shaped strip has a mating threaded groove that is aligned with the inner thread of the positioning threaded groove and the mating threaded groove. Fastening bolts are installed in the internal threads of the positioning threaded groove and the mating threaded groove.

[0010] Preferably, the auxiliary unblocking component includes an external threaded sleeve, a filter tube, and an internal threaded sleeve. The external threaded sleeve is provided in four sets. In the first set, the external threaded sleeve is fixedly installed on the outer wall of the Y-shaped tube at both drain ends. In the second set, the external threaded sleeve is fixedly installed on the outer wall of the Y-shaped tube at both inlet ends. The filter tube is provided in two sets, and the internal threaded sleeve is fixedly installed on the outer wall of both sides of the filter tube, with the internal threaded sleeve threaded onto the outside of the external threaded sleeve.

[0011] Preferably, the filter tube consists of two tube structures. The first tube structure is a telescopic tube structure, and the second tube structure is a solid tube structure. A filter screen hopper is fixedly installed on the inner wall of the annular tube at the solid tube position, and the front section of the filter screen hopper is a trapezoidal structure. A viewing window is embedded inside the annular tube at the filter screen hopper installation position.

[0012] Preferably, four sets of guide plates are installed at staggered positions on the inner wall of the annular surface of the Y-shaped pipe located at the position of the main flow pipe, and strip-shaped drainage grooves are equally spaced on the outer wall of the four sets of guide plates located on the water-facing side.

[0013] Preferably, the four sets of guide vanes are arranged in an inclined structure, and the spacing between adjacent sets of guide vanes is distributed in an increasing manner.

[0014] The beneficial effects of this utility model are:

[0015] 1. In use, this new rainwater pipe interface structure achieves precise docking between the inlet pipe and the Y-shaped pipe through the interface plug-in assembly. The circumferential distribution of four sets of limiting T-shaped strips and limiting T-shaped grooves ensures the accuracy of installation positioning. Combined with the positioning threaded groove, docking threaded groove and fastening bolt fixing structure, a multi-layer reinforcement design is formed, which solves the problem of interface loosening and misalignment caused by the lack of positioning reinforcement in the existing structure. At the same time, the combination of plug-in installation and bolt fixing simplifies the installation process compared with the traditional single flange connection or simple plug-in structure, ensuring the connection stability under long-term water flow impact and improving construction efficiency.

[0016] 2. This new rainwater pipe interface structure addresses the problems of impurity accumulation and difficulty in clearing blockages in existing pipe interfaces through the design of auxiliary unblocking components. The filter pipe uses a telescopic tube structure to block larger impurities, while the trapezoidal filter screen intercepts fine particles. This dual filtration mechanism significantly reduces the risk of pipe blockage. The viewing window allows for real-time observation of the filter screen's blockage status, facilitating timely handling. Furthermore, two sets of Y-shaped pipe branches, combined with control valves, form a dual-path drainage design. When clearing blockages, simply close the control valve of the pipe to be cleaned and switch to the other path to ensure normal rainwater discharge without disassembling a large number of pipes. The threaded connection structure between the filter pipe and the external threaded sleeve further simplifies the disassembly and cleaning process, significantly improving maintenance convenience.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a novel rainwater pipe interface structure, including an inlet pipe 1, a drain pipe 2, and a Y-shaped pipe 3. The inlet pipe 1 is located on the side of the drain pipe 2. Two sets of Y-shaped pipes 3 are provided. The first set of Y-shaped pipes 3 is installed on the side of the pipe body of the inlet pipe 1 at the drain end, and the second set of Y-shaped pipes 3 is installed on the side of the pipe body of the drain pipe 2 at the inlet end. Control valves 4 are installed inside the two branch pipes of the first set of Y-shaped pipes 3. The valve stem rotation ends of the two sets of control valves 4 are located outside the Y-shaped pipes 3.

[0029] An interface plug-in assembly 5 is installed between the water inlet pipe 1 and the Y-shaped pipe 3, and an auxiliary unblocking assembly 6 is installed between the middle positions of the two sets of Y-shaped pipes 3.

[0030] The interface plug-in assembly 5 includes a positioning outer ring 501, a positioning inner ring 502, a limiting T-shaped strip 503, and a limiting T-shaped groove 504. A flange is fixedly installed on the outer wall of the inlet pipe 1 at the inlet end. The positioning outer ring 501 is fixedly installed on the outer wall of the inlet pipe 1 at the outlet end. The positioning inner ring 502 is fixedly installed on the outer wall of the first group of Y-shaped pipes 3 at the inlet end, and the positioning inner ring 502 is slidably installed inside the positioning outer ring 501. Four sets of positioning inner rings 502 are circumferentially fixedly installed on the outer wall of the side of the annular surface. The limiting T-shaped strip 503 has four sets of limiting T-shaped grooves 504 on the inner side wall of the positioning outer ring 501 located on the annular surface for the insertion and installation of the limiting T-shaped strip 503. The outer side wall of the positioning outer ring 501 located on the annular surface has four sets of positioning threaded grooves 505 circumferentially through, and the positioning threaded grooves 505 are in communication with the internal space of the limiting T-shaped grooves 504. The outer side wall of the limiting T-shaped strip 503 has a mating threaded groove 506 aligned with it. The internal threads of the positioning threaded grooves 505 and the mating threaded grooves 506 are fitted with fastening bolts 507.

[0031] The T-shaped limit bar 503 and the T-shaped limit groove 504 here serve to position and connect the water inlet pipe 1 and the Y-shaped pipe 3, so as to ensure that the installation positions of the water inlet pipe 1 and the Y-shaped pipe 3 are accurate.

[0032] The auxiliary unblocking component 6 includes an external threaded sleeve 601, a filter pipe 602, and an internal threaded sleeve 603. There are four sets of external threaded sleeves 601. The outer walls of the first set of Y-shaped pipes 3 at the two drain ends are fixedly installed with external threaded sleeves 601. The outer walls of the second set of Y-shaped pipes 3 at the two inlet ends are fixedly installed with external threaded sleeves 601. There are two sets of filter pipes 602. The outer walls of both sides of the filter pipe 602 are fixedly installed with internal threaded sleeves 603. The internal threaded sleeves 603 are threaded onto the outside of the external threaded sleeves 601.

[0033] The filter tube 602 here is designed to filter solid impurities in rainwater to prevent the pipe from becoming clogged.

[0034] The filter tube 602 consists of two tube structures. The first tube structure of the filter tube 602 is a telescopic tube structure, and the second tube structure of the filter tube 602 is a solid tube structure. A filter hopper 604 is fixedly installed on the inner wall of the annular tube where the filter tube 602 is located. The front section of the filter hopper 604 is a trapezoidal structure. A viewing window 605 is embedded in the annular tube where the filter hopper 604 is installed.

[0035] The filter hopper 604 is designed to isolate solid impurities in rainwater, while the telescopic tube structure is designed to block larger impurities in the rainwater. The viewing window 605 is designed to observe the accumulation of impurities inside the filter hopper 604 so that it can be cleared in time.

[0036] Four sets of guide plates 701 are installed at staggered positions on the inner wall of the annular surface of the Y-shaped pipe 3 at the position of the main flow pipe. Strip-shaped drainage grooves 702 are equally spaced on the outer wall of the four sets of guide plates 701 at the water-facing position. The guide plates 701 are distributed in an inclined structure, and the spacing between adjacent sets of guide plates 701 is distributed in an increasing manner.

[0037] Here, the guide plate 701 is set as an inclined structure to facilitate the diversion of rainwater, and the guide plate 701 is set as an incrementally spaced distribution so that the initial end can easily buffer the rainwater, and the end end will not affect the normal drainage of rainwater.

[0038] Working principle: See Figures 1-3 As shown, when it is necessary to install the water inlet pipe 1 to the side of the Y-shaped pipe 3, the Y-shaped pipe 3 should first be adjusted to a suitable position and then the limiting T-shaped strip 503 on its side should be inserted into the corresponding limiting T-shaped groove 504. When the limiting T-shaped strip 503 moves to the bottom of the limiting T-shaped groove 504, the installation positions of the positioning thread groove 505 and the mating thread groove 506 should coincide. Then, the fastening bolt 507 should be passed through the positioning thread groove 505 and screwed to the bottom of the mating thread groove 506 to complete the locking installation of the water inlet pipe 1 and the Y-shaped pipe 3. It should be noted that the installation principle of the Y-shaped pipe 3 and the drain pipe 2 is the same as above, and will not be elaborated on here.

[0039] See Figure 1 and Figure 4 As shown, when the filter tube 602 needs to be installed in the middle position of the two sets of Y-shaped tubes 3, simply adjust the filter tube 602 to a suitable position and screw the inner threaded sleeves 603 on both sides to the outside of the outer threaded sleeves 601 to complete the installation. Disassembly is the same.

[0040] See Figures 1-6As shown, after the internal piping of the device is assembled, the inlet pipe 1 and the outlet pipe 2 need to be connected to the existing piping system. When rainwater flows into the device through the external pipe, it will first enter the inlet pipe 1 and then be sent to the first set of Y-shaped pipes 3. Since the first set of Y-shaped pipes 3 is equipped with four sets of guide plates 701, the impact of the rainwater will be automatically blocked and buffered by the guide plates 701 to reduce the vibration of the pipe. Then the rainwater is sent to one of the filter pipes 602 through the first set of Y-shaped pipes 3. Note that in actual use, only one of the two sets of control valves 4 needs to be opened to keep one of the pipes unobstructed.

[0041] Then, after the rainwater enters the interior of a set of filter pipes 602, the larger impurities in the rainwater will be automatically isolated by the pipe folds of the telescopic pipe, while the smaller solid impurities in the rainwater will be automatically isolated inside the filter hopper 604. Then the filtered rainwater will be discharged to the outside of the device through the second set of Y-shaped pipes 3.

[0042] The setting of window 605 here makes it easy to observe the clogging of filter hopper 604. When there is a lot of clogging inside a single filter hopper 604 and it needs to be cleaned, the control valve 4 of this line is closed and the control valve 4 of another line is opened to ensure normal drainage of rainwater. Then, the filter tube 602 of the clogging part can be removed and cleaned according to the above principle.

[0043] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
