Description

Technical Field

[0001] This utility model relates to the field of municipal water supply and drainage technology, specifically to a non-powered automatic rainwater and sewage diversion device for buildings. 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 room for flow adjustment. Traditional solutions have limitations. Therefore, to effectively solve these problems, a non-powered automatic rainwater and sewage separation device for buildings is needed.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. During use, most existing automatic rainwater and sewage diversion devices require manual operation of the outlet valve to switch the direction of water flow. Manually switching the outlet valve is not only inefficient but also extremely inconvenient, thus significantly reducing the convenience of the diversion device during use; 2. After rainwater enters the diversion device, it usually contains a small amount of garbage. Existing diversion devices lack a filtration mechanism, which prevents the diversion device from filtering the garbage mixed in the rainwater. This causes the small amount of garbage mixed in the rainwater to easily clog the sewage outlet, thereby reducing the subsequent sewage discharge effect of the diversion device. Utility Model Content

[0004] The purpose of this utility model is to provide a non-powered automatic rainwater and sewage diversion device for buildings, to solve the problems mentioned in the background art, where existing automatic rainwater and sewage diversion devices mostly require manual operation of the outlet valve to switch the direction of water flow, thus greatly reducing the convenience of the diversion device during use, and existing diversion devices cannot filter garbage mixed in rainwater, causing small amounts of garbage mixed in rainwater to easily clog the sewage outlet, thereby reducing the subsequent sewage discharge effect of the diversion device. To achieve the above objectives, this utility model provides the following technical solution: a non-powered automatic rainwater and sewage diversion device for buildings, including a shell assembly and a frame. A water outlet pipe is provided in the middle of the bottom of the shell assembly, and several connecting rods are provided at the top of the water outlet pipe. Diversion plates are provided at the top of the connecting rods. A guide pipe is provided on one side of the bottom of the shell assembly, and a float ball is provided at the bottom of the inner part of the guide pipe. A sewage drain pipe is provided on one side of the guide pipe. A positioning seat is provided on one side of the inner bottom of the shell assembly. Slider blocks are provided on both sides of the frame, and a filter screen is provided at the bottom of the frame.

[0005] More preferably, the outer casing assembly includes a diverter body, with a water inlet pipe at the top of the diverter body and grooves formed on the two inner walls of the diverter body.

[0006] More preferably, the groove and the slider are configured to slide together.

[0007] More preferably, the diverter plate is configured as a bent structure.

[0008] More preferably, the internal dimensions of the guide tube are the same as the external dimensions of the float.

[0009] More preferably, the bottom end of the filter screen is provided as an inclined structure.

[0010] More preferably, the bottom end of the positioning seat has a groove, and the internal dimensions of the groove are consistent with the external dimensions of the float.

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

[0012] In this invention, the combination of a guide pipe, a ball valve, and a positioning seat enables the automatic rainwater and sewage diversion device for buildings to achieve the raising and lowering of the float under the combined action of gravity and buoyancy during use, thereby connecting the opening and closing of the sewage drainage pipe. This allows the water flow direction to be switched without manual operation, thus greatly improving the convenience of the automatic rainwater and sewage diversion device during use.

[0013] In this utility model, the combination of the frame, slider and filter screen enables the automatic rainwater and sewage diversion device for buildings to filter and screen garbage mixed in rainwater during use, solving the problem of rainwater mixed with garbage causing blockage of the automatic rainwater and sewage diversion device, thereby greatly increasing the sewage discharge effect of the main body of the diversion device and thus meeting the requirements of automatic rainwater and sewage diversion devices for buildings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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-based automatic rainwater and sewage diversion device without power, comprising a housing assembly 1 and a frame 2. A water outlet pipe 3 is provided at the bottom center of the housing assembly 1, and a plurality of connecting rods 4 are provided at the top of the water outlet pipe 3. A diversion plate 5 is provided at the top of the plurality of connecting rods 4. A guide pipe 6 is provided on one side of the bottom of the housing assembly 1. A float ball 7 is provided at the bottom of the inside of the guide pipe 6. A sewage drain pipe 8 is provided on one side of the guide pipe 6. A positioning seat 9 is provided on one side of the bottom of the inside of the housing assembly 1. Slider blocks 10 are provided on both sides of the frame 2. A filter screen 11 is provided at the bottom of the frame 2.

[0021] In this embodiment, as Figure 1As shown, the outer casing assembly 1 includes a diverter body 101, with an inlet pipe 102 at the top of the diverter body 101, and grooves 103 formed on the two inner walls of the diverter body 101.

[0022] In this embodiment, as Figure 1 As shown, the slide groove 103 and the slider 10 are connected by a sliding connection; this increases the stability of the frame 2 during movement, thereby preventing the frame 2 from shifting or tilting during movement.

[0023] In this embodiment, as Figure 2 As shown, the diversion plate 5 is designed as a bent structure to prevent impurities in the accumulated water from obstructing the main body 101 of the diversion device, thereby increasing the sewage discharge effect of the main body 101 of the diversion device.

[0024] In this embodiment, as Figure 3 As shown, the internal dimensions of the guide tube 6 are consistent with the external dimensions of the float 7, so that the float 7 moves in a single direction and avoids the float 7 from deviating or shifting during movement.

[0025] In this embodiment, as Figure 2 As shown, the bottom of the filter screen 11 is designed as an inclined structure; this allows for the filtration and screening of garbage mixed in rainwater, solving the problem of rainwater mixed with garbage causing blockage of the automatic rainwater and sewage diversion device, thereby significantly increasing the sewage discharge effect of the diversion device body 101, and thus meeting the requirements of the building's non-powered automatic rainwater and sewage diversion device.

[0026] In this embodiment, as Figure 3 As shown, a groove is provided at the bottom of the positioning seat 9, and the internal dimensions of the groove are consistent with the external dimensions of the float 7; so that the float 7 can rise and fall under the combined action of gravity and buoyancy, so as to connect the opening and closing of the sewage drain pipe 8, thereby enabling the water flow discharge direction to be switched without manual operation, thus greatly improving the convenience of the automatic rainwater and sewage separator during use.

[0027] The usage and advantages of this utility model: The working process of this non-powered automatic rainwater and sewage separator in buildings is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the inlet pipe 102 and outlet pipe 3 of the main body 101 of the diverter are connected to the external pipe. When it is sunny or the rain is light, rainwater between buildings enters the main body 101 of the diverter through the external pipe and the inlet pipe 102. The filter screen 11 can filter and screen the garbage in the rainwater, solving the problem of rainwater mixed with garbage causing blockage of the automatic rainwater and sewage diverter, thereby greatly increasing the sewage discharge effect of the main body 101 of the diverter. The filtered rainwater will fall to the bottom of the diverter body 101 through the diversion plate 5. The rainwater will flow out through the guide pipe 6 and the sewage drain pipe 8. When it rains and there is a heavy rain, when a lot of rainwater accumulates in the main body 101 of the diverter, the float 7 will be buoyed by the rising water and gradually move upward under the limit of the guide pipe 6 and seal the positioning seat 9, so that the rainwater in the main body 101 of the diverter is cleared. When the water level rises to its highest point, the rainwater in the main body 101 of the diverter accumulates and overflows through the outlet pipe 3, thanks to the cooperation of the float 7 and the positioning seat 9. As the amount of rainwater decreases, the water level in the main body 101 of the diverter drops continuously, and the float 7 also slowly descends in the guide pipe 6 until it falls completely, leaving the sewage drain pipe 8 open. The remaining rainwater will then flow out through the sewage drain pipe 8, thus enabling the water flow direction to be switched without manual operation, thereby greatly improving the convenience of the automatic rainwater and sewage diverter during use. When it is necessary to clean the garbage in the filter screen 11, open the main body 101 of the diverter and then pull out the frame 2, so that the frame 2 can be moved out with the cooperation of the slide groove 103 and the slider 10, thereby cleaning and replacing the filter screen 11, thus meeting the requirements of the building's non-powered automatic rainwater and sewage diverter.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
