Description

Technical Field

[0001] This utility model belongs to the field of rainwater and sewage separation technology, specifically relating to an intelligent rainwater and sewage separation device. Background Technology

[0002] Existing intelligent rainwater and sewage separation devices all require pure rainwater as the detection water to determine whether it is raining. The buoyancy change caused by this rainwater provides the power for switching the separation valves. For example, see the rainwater and sewage separation device mentioned in patent application CN220704714U. The source of the detection water is generally pure rainwater downpipe, inlet, drainage ditch, or a specially set up independent water collection mechanism. However, in real-world applications, due to limitations in installation location, the above-mentioned water collection mechanisms are often inconvenient to install or have high installation costs, thus affecting the actual installation and use of the rainwater and sewage separation device, indicating room for improvement. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an intelligent rainwater and sewage separation device to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A smart rainwater and sewage separation device is provided, including a rainwater chamber, a water distribution chamber fixed inside the rainwater chamber, a mixing inlet and a sewage outlet on the water distribution chamber, a rainwater outlet on one side of the rainwater chamber, a rainwater collection chamber located on the inner top of the rainwater chamber and above the water distribution chamber, an overflow outlet on one side of the top of the rainwater collection chamber, a flap gate movably installed inside the water distribution chamber, a discrimination chamber fixed between the flap gate and the rainwater collection chamber, the bottom of the rainwater collection chamber communicating with the discrimination chamber, an outlet hole at the bottom of the discrimination chamber, and a lever counterweight assembly below the discrimination chamber. The discrimination chamber acts on the lever counterweight assembly according to the current rainfall conditions and adjusts the working position of the lever counterweight assembly, thereby driving the flap gate to open and close the sewage outlet accordingly.

[0006] As described in the intelligent rainwater and sewage separation device, the top of the rainwater collection chamber is fixed with a rainwater collection well cover that communicates with the interior of the rainwater collection chamber. The rainwater collection well cover is evenly provided with several rainwater collection holes. A water collection pipe is provided at the bottom of the rainwater collection chamber and is located above the discrimination chamber.

[0007] As described in the intelligent rainwater and sewage separation device, the bottom of the discrimination chamber and the top of the flap gate are fixedly connected by a guide rod.

[0008] As described in the intelligent rainwater and sewage separation device, a guide ring is sleeved on the outer periphery of the guide rod, and the guide ring is fixedly connected to the inner wall of the water separation chamber by a rod.

[0009] As described in the intelligent rainwater and sewage separation device, the lever counterweight assembly includes a rotating component, the middle of which is hinged to the inside of the housing of the water separation chamber, one end of which is connected to a counterweight block, and the other end of which can abut against the bottom of the discrimination chamber.

[0010] In the intelligent rainwater and sewage separation device described above, the rotating component is a lever or a shaft.

[0011] The beneficial effects of this utility model's technical solution are:

[0012] 1. This utility model provides an intelligent rainwater and sewage separation device, which uses the internal rainwater collection chamber of the upper rainwater collection well cover of the device itself as the water collection mechanism, which greatly reduces the construction difficulty and increases the applicability of the product.

[0013] 2. This utility model provides an intelligent rainwater and sewage separation device. By adopting a gravity change mode of a discrimination chamber combined with a lever counterweight component, it replaces the buoyancy change mode of the existing intelligent rainwater and sewage separation device, thereby reducing the demand for discrimination water and improving the sensitivity of sewage outlet opening and closing control.

[0025] The details of the present invention will now be discussed with reference to the accompanying drawings, which are illustrated by way of example only. In the drawings, similar features or components may be labeled with the same reference numerals.

[0026] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein, their equivalents, and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0027] See Figure 1As shown, the present invention's intelligent rainwater and sewage separation device includes a rainwater chamber 100, with a rainwater outlet O2 on one side of the rainwater chamber 100. A water distribution chamber 300 is fixed inside the rainwater chamber 100, and a mixing inlet I and a sewage outlet O1 are respectively provided on the water distribution chamber 300. The mixing inlet I is connected to a mixing pipe. Depending on the weather conditions, the water flowing in through the mixing pipe from the mixing inlet I is sewage on sunny days, while rainwater flows in through the mixing pipe from the mixing inlet I during rainfall (at this time, even if sewage flows in, its flow rate is small and negligible compared to rainwater). Correspondingly, the sewage outlet O1 is connected to the sewage pipe network, while the rainwater outlet O2 is connected to the rainwater pipe network.

[0028] As a preferred option, such as Figure 2 As shown, in this embodiment, the mixed-flow inlet I and the sewage outlet O1 are located on the same side of the rainwater chamber 100 and connected to the water distribution chamber 300, while the rainwater outlet O2 is located on the opposite side of the rainwater chamber 100 and connected to the interior of the rainwater chamber 100, to facilitate the overall installation and layout of the intelligent rainwater and sewage separation device. For ease of installation and layout, those skilled in the art may also set the mixed-flow inlet I, sewage outlet O1, and rainwater outlet O2 to other relative directions and positions.

[0029] The improvement of this embodiment compared with the prior art is that a rainwater collection chamber 200 is provided on the inner top of the rainwater collection chamber 100 and above the water distribution chamber 300. The top of the rainwater collection chamber 100 and the rainwater collection chamber 200 are fixed with a rainwater collection well cover that communicates with the inside of the rainwater collection chamber 200. By using the rainwater collection well cover inside the device itself as the water collection mechanism, the construction difficulty is greatly reduced and the applicability of the product is increased.

[0030] As shown in the figure, several rainwater collection holes 201 are evenly distributed on the rainwater collection manhole cover, so that the rainwater Y2 falling on the rainwater collection manhole cover can flow into the rainwater collection chamber 200 through the rainwater collection holes 201. A water collection pipe 202 is provided at the bottom of the rainwater collection chamber 200. The water collection pipe 202 is located above the discrimination chamber 400. The rainwater inside the rainwater collection chamber 200 can flow into the discrimination chamber 400 through the bottom water collection pipe 202 and be used as discrimination water.

[0031] like Figure 1 As shown, the top of the rain collection chamber 200 is provided with an overflow port 203 so that when the rainfall is large, the rainwater inside the rain collection chamber 200 can overflow into the rainwater chamber 100 through the overflow port 203.

[0032] The water distribution chamber 300 is equipped with a flap gate 301. A discrimination chamber 400 is fixed on top of the flap gate and below the rainwater collection chamber 200. The bottom of the discrimination chamber 400 is fixedly connected to the top of the flap gate 301 through a guide rod 302. The quality change of the water inside the discrimination chamber 400 is detected, and the guide rod 302 drives the flap gate 301 at the bottom to move up and down synchronously, thereby realizing the opening and closing control of the sewage outlet O1.

[0033] To ensure that the flap gate 301 can only move up and down within a preset track, a guide ring 303 is fitted around the outer periphery of the guide rod 302. The guide ring 303 is fixedly connected to the inner wall of the water distribution chamber 300 through the support rod 304. Thus, the guide ring 303 limits the guide rod 302 inside, ensuring that the guide rod 302 can only move up and down within the inner diameter of the guide ring 303, thereby driving the bottom flap gate 301 to only move up and down in the vertical direction.

[0034] The bottom of the discrimination chamber 400 is also equipped with a lever counterweight assembly. The discrimination chamber 400 can adjust the working position of the lever counterweight assembly according to the current rainfall conditions, thereby driving the bottom flap gate 301 to open and close the sewage outlet O1 accordingly.

[0035] like Figure 1 As shown, the lever counterweight assembly is located at the bottom of the discrimination chamber 400. In this embodiment, the lever counterweight assembly includes a rotating component 305. The middle part of the rotating component 305 is hinged inside the housing of the water distribution chamber 300. One end of the rotating component 305 is connected to a counterweight block 306, and the other end of the rotating component 305 can abut against the bottom of the discrimination chamber 400. The rotating component can be configured with a corresponding shape and structure according to actual needs, such as a lever or a pivot. To increase the contact area with the bottom of the discrimination chamber 400 and thus improve the upward support stability of the discrimination chamber 400, the other end of the rotating component 305 is preferably configured as a long strip U-shaped structure, so that it fits around the outer periphery of the guide rod 302 through a U-shaped groove, providing stable support while achieving good fit with the guide rod 302.

[0036] Furthermore, the counterweight 306 in this embodiment is configured as follows:

[0037] When the discrimination chamber 400 is empty, the counterweight 306 at one end of the rotating component 305 is in a low position, and the other end of the discrimination chamber 400 is in a high position through the guide rod 302. At this time, the sewage outlet O1 is opened.

[0038] When the discrimination chamber 400 is full, the counterweight 306 at one end of the rotating component 305 is in a high position, and the other end of the discrimination chamber 400 of the rotating component 305 is in a low position by pressing down the flap gate 301 through the guide rod 302. At this time, the sewage outlet O1 is closed.

[0039] This configuration ensures that when the discrimination chamber 400 is empty, the rotating component 305 rotates clockwise under the weight of the counterweight 306, causing its left end to contact the bottom of the discrimination chamber 400, thus supporting the chamber at a higher position and pulling the flap gate 301 upward to open the sewage outlet O1. When the discrimination chamber is full, the rotating component 305 rotates counterclockwise, causing the chamber 400 to descend to a lower position and pressing the flap gate 301 downward to close the sewage outlet O1. Those skilled in the art can also set the critical point for the lever counterweight component's action to any desired liquid level between an empty and full discrimination chamber, according to actual rainwater and sewage separation requirements.

[0040] As a further preferred option, the bottom of the discrimination chamber 400 is provided with an outlet hole 401 so that the discrimination water that enters the discrimination chamber 400 after the rain stops can slowly flow out from the outlet hole 401 at the bottom of the discrimination chamber 400.

[0041] like Figure 3 The diagram shows the structural installation of the intelligent rainwater and sewage separation device provided in this embodiment. The water flow direction is shown by the arrow in the diagram. By installing the intelligent rainwater and sewage separation device inside the road R, and using the rainwater collection chamber inside the upper rainwater collection manhole cover of the device itself as a water collection mechanism, the sewage flowing in from the mixing inlet I through the mixing pipe can flow to the sewage pipe network through the sewage outlet O1 on sunny days. On rainy days, the rainwater flowing in from the mixing inlet I through the mixing pipe, as well as the runoff rainwater Y1 and the rainwater Y2 flowing in from the upper rainwater collection manhole cover, can flow to the rainwater pipe network through the rainwater outlet O2.

[0042] The specific working process of this embodiment is as follows:

[0043] On a sunny day, the counterweight 306 pulls down the right end of the rotating component 305, causing the left end of the rotating component 305 to lift the discrimination chamber 400, which in turn raises the guide rod 302 and the flap gate 301. At this time, the sewage outlet O1 opens, and the sewage flowing in from the mixed-flow inlet I enters the water distribution chamber 300 and then flows into the sewage pipe network through the sewage outlet O1. Figure 4 As shown.

[0044] When it rains, rainwater enters the rainwater collection chamber 200 through the rainwater collection manhole cover, and then flows into the discrimination chamber 400 through the water collection pipe 202. The increased weight of the discrimination chamber 400 presses down on the left end of the rotating component 305, causing the rotating component 305 to rotate counterclockwise around the hinge point. This, in turn, pushes the guide rod 302 and the flap gate 301 down until the sewage outlet O1 is closed. Figure 5 As shown; at this time, the rainwater flowing in from the mixed-flow inlet I enters the water distribution chamber 300, and because the sewage outlet O1 is closed, the liquid level inside the water distribution chamber 300 rises until it overflows into the rainwater chamber 100, and then enters the rainwater pipe network through the rainwater outlet O2, as shown. Figure 6As shown; if it rains continuously or the rainfall is heavy, the rainwater level entering the rainwater collection chamber 200 will rise. The rainwater inside the collection chamber 200 can then flow into the rainwater collection chamber 100 through the overflow outlet 203, and then into the rainwater pipe network through the rainwater outlet O2, thus preventing water accumulation on the surface of the rainwater collection manhole cover. Figure 7 As shown.

[0045] After the rain stops, the water in the discrimination chamber 400 slowly flows out through the outlet 401. The weight of the discrimination chamber 400 decreases, and the right-end counterweight 306 pulls down the rotating component 305 again, causing it to rotate clockwise around the hinge point. The left end of the rotating component 305 lifts the discrimination chamber 400, raising the guide rod 302 and the flap gate 301, thus reopening the sewage outlet O1. Figure 8 As shown; thereafter, sewage flows into the mixed-flow inlet I, and after entering the distribution chamber 300, the sewage flows into the sewage pipe network through the sewage outlet O1, as shown. Figure 4 As shown.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
