Description

Technical Field

[0001] This utility model relates to the field of diverter technology, specifically a building rainwater and sewage diverter with a self-closing device. Background Technology

[0002] Currently, urban wastewater treatment projects are being vigorously promoted. However, due to design and other reasons, mixed-flow risers are being connected to residential sewage systems. Because these risers lack flow control measures, large amounts of rainwater from rooftops are flowing into the community's sewage network, obstructing sewage channels. Furthermore, the limited treatment capacity of municipal sewage treatment plants causes sewage to overflow into rivers, polluting the water environment. Mixed-flow rainwater from urban residential buildings is a common problem. Currently, intercepting wells are often constructed using civil engineering methods below the rainwater risers. This not only requires on-site construction and has a significant environmental impact, but is also often not feasible due to site constraints. Additionally, the interception capacity of these wells is fixed, with no flow adjustment space. Traditional solutions have limitations. Therefore, to effectively solve these problems, a building rainwater and sewage separation device with a self-closing mechanism is needed.

[0003] An existing patent (publication number: CN207121974U) discloses a building stormwater and sewage diversion device, relating to the field of diversion device equipment. The key technical points of the device are: a building stormwater and sewage diversion device includes a housing, inside which are sequentially arranged a filter chamber, a buffer control chamber, and a sewage discharge chamber. An overflow pipe is also provided inside the housing. The filter chamber has a combined stormwater and sewage inlet, and a pre-filter is located below the combined stormwater and sewage inlet. An overflow inlet is located above the pre-filter on the side away from the combined stormwater and sewage inlet, and a flow passage is located below the overflow inlet. The buffer control chamber has a top plate, separated from the filter chamber and sewage discharge chamber by side partitions. Each partition is divided into an upper partition and a lower partition. The lower partition is integrally formed with the housing; the upper partition is integrally formed with the top plate. The sewage discharge chamber has a sewage discharge outlet at the bottom and a rainwater discharge outlet on the side wall. The buffer control chamber has a self-closing device for controlling the flow of the sewage discharge outlet. This device can filter all liquids in the stormwater pipes, realizing the separation of stormwater and sewage in the building's stormwater pipes. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing rainwater and sewage separators lack a self-closing mechanism. When the internal mechanism of the separator is damaged and requires maintenance, the inlet of the separator cannot be sealed, causing rainwater to continuously flow into the separator through the inlet, thus significantly reducing the work efficiency during separator maintenance; 2. During use, the existing separator self-closing mechanism requires the use of various auxiliary tools for control and operation, which is cumbersome, time-consuming, and labor-intensive, greatly increasing the labor intensity of the staff and reducing the convenience of the separator during use. Utility Model Content

[0004] The purpose of this utility model is to provide a building rainwater and sewage separator with a self-closing device to solve the problems mentioned in the background art, namely, the lack of a self-closing mechanism in existing rainwater and sewage separators. When the internal mechanism of the separator is damaged and maintenance is required, the inlet of the separator cannot be sealed, causing rainwater to continuously flow into the separator through the inlet, thus greatly reducing the work efficiency during separator maintenance. In addition, some separators require various auxiliary tools to control the self-closing mechanism during use, which is cumbersome, time-consuming and labor-intensive, greatly increasing the labor intensity of the staff and reducing the convenience of the separator during use. To achieve the above objectives, this utility model provides the following technical solution: a building rainwater and sewage separator with a self-closing device, comprising a housing assembly, a positioning seat provided on one side of the inner side of the housing assembly, the positioning seat having a conical groove, a threaded rod provided on the inner side of the housing assembly away from the positioning seat via a bearing, a threaded sleeve provided on the outside of the threaded rod, one end of the threaded sleeve being connected to the middle of one side of a mounting plate, a conical sealing plate provided on the other side of the mounting plate, guide blocks provided on both sides of the outer side of the mounting plate, and guide rods parallel to the threaded rod penetrating through the interior of the two guide blocks.

[0009] More preferably, the conical sealing plate is made of rubber.

[0010] More preferably, the guide rod and the guide block are configured to slide together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this utility model, the combination of the mounting plate, the conical sealing plate and the positioning seat enables the building rainwater and sewage diversion device with self-closing device to achieve the sealing treatment of the inlet pipe according to the user's needs during use. This solves the problem that rainwater will continuously flow into the rainwater and sewage diversion device body through the inlet when maintaining the body of the rainwater and sewage diversion device, thereby greatly improving the work efficiency during the maintenance of the diversion device.

[0013] In this utility model, the combination of handle, threaded rod and threaded sleeve enables the building rainwater and sewage diversion device with self-closing device to quickly adjust the position of the mounting plate during use, greatly improving the convenience of the self-closing mechanism during use, thereby reducing the labor intensity of workers and meeting the requirements of building rainwater and sewage diversion devices with self-closing devices.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a building rainwater and sewage diversion device with a self-closing device, including a housing assembly 1, a positioning seat 2 is provided on one side of the inner side of the housing assembly 1, the positioning seat 2 has a conical groove 3, a threaded rod 4 is provided on the inner side of the housing assembly 1 away from the positioning seat 2 through a bearing, a threaded sleeve 5 is provided on the outside of the threaded rod 4, one end of the threaded sleeve 5 is connected to the middle of one side of the mounting plate 6, a conical sealing plate 7 is provided on the other side of the mounting plate 6, guide blocks 8 are provided on both sides of the outside of the mounting plate 6, and guide rods 9 parallel to the threaded rod 4 pass through the interior of the two guide blocks 8.

[0021] In this embodiment, as Figure 1As shown, the outer casing assembly 1 includes a rainwater and sewage diversion device body 101, a housing 102 is provided at the top of the rainwater and sewage diversion device body 101, and a handle 103 is provided on one side of the housing 102.

[0022] In this embodiment, as Figure 1 As shown, the bottom of the inner part of the box 102 is set as an inclined structure; through the inclined box 102, rainwater and sewage can flow smoothly into the interior of the rainwater and sewage diversion device body 101 by their own gravity.

[0023] In this embodiment, as Figure 2 As shown, the internal dimensions of the conical groove 3 are consistent with the external dimensions of the conical sealing plate 7; this allows for the sealing treatment of the inlet pipe according to the user's needs, solving the problem that rainwater would continuously flow into the interior of the rainwater and sewage diverter body 101 through the inlet when maintaining the interior of the diverter body 101, thereby greatly improving the work efficiency during diverter maintenance.

[0024] In this embodiment, as Figure 3 As shown, the central axis of the mounting plate 6 is aligned with the central axis of the threaded rod 4; this enables rapid adjustment of the position of the mounting plate 6, significantly improving the convenience of the self-closing mechanism during adjustment and use, thereby reducing the labor intensity of staff and meeting the requirements of building rainwater and sewage diversion devices with self-closing devices.

[0025] In this embodiment, as Figure 4 As shown, the conical sealing plate 7 is made of rubber; this increases the sealing effect between the positioning seat 2 and the conical sealing plate 7, thereby preventing leakage during use.

[0026] In this embodiment, as Figure 4 As shown, the guide rod 9 and the guide block 8 are connected by a sliding connection; this increases the stability of the mounting plate 6 during movement, thereby preventing the mounting plate 6 from rotating with the rotation of the threaded rod 4 during movement.

[0027] The usage and advantages of this utility model: The building stormwater and sewage separator with a self-closing device operates as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, connect the inlet and outlet pipes of the main body 101 of the rainwater and sewage diversion device to the external water pipe. When it is necessary to automatically close the diversion device, rotate the handle 103, causing the handle 103 to drive the threaded rod 4 to rotate. At this time, the threaded rod 4 drives the mounting plate 6 to move through the threaded sleeve 5. Simultaneously, the mounting plate 6, with the cooperation of the guide rod 9 and the guide block 8, drives the conical sealing plate 7 to move synchronously until the conical sealing plate 7 is embedded in the conical groove 3 on one side of the positioning seat 2, so that a seal is formed between the conical groove 3 and the conical sealing plate 7. The system allows for the sealing of the inlet pipe according to user needs, resolving the issue of rainwater continuously flowing into the main body 101 of the rainwater and sewage separator during maintenance. This significantly improves the efficiency of separator maintenance. The threaded rod 4 and threaded sleeve 5 enable rapid adjustment of the mounting plate 6, greatly enhancing the convenience of the self-closing mechanism during use and reducing the workload of staff. This meets the requirements for building rainwater and sewage separators with self-closing devices.
