Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation technology, and in particular to rainwater and sewage separation devices for buildings. Background Technology

[0002] Building stormwater and sewage separation refers to the separation of residential sewage from rainwater. Stormwater and sewage separation is a drainage system that separates rainwater and sewage, each using its own pipeline for discharge or subsequent treatment. Rainwater is discharged directly into rivers through the stormwater pipe network, while sewage is collected through the sewage pipe network and sent to sewage treatment plants for treatment, thus preventing sewage from directly entering rivers and causing pollution.

[0003] Currently, rainwater and sewage are distinguished by the amount of water flow. However, with the development of society, residents' get off work hours are basically the same, and the discharge time of sewage from balconies such as for laundry is relatively concentrated. This may lead to miscontrol, causing sewage to enter the rainwater pipe network.

[0004] In the prior art, patent application number CN202321883631.3, filed on 2023-07-17, discloses an intelligent rainwater and sewage diversion device, including an installation box, a mixed-flow inlet pipe disposed on one side of the installation box, a rainwater drain pipe disposed on the other side of the installation box, a water quality discrimination pipe disposed on the front side of the installation box, and a sewage drain pipe disposed at the bottom of the installation box. It also includes: an isolation frame disposed inside the installation box for collecting rainwater; and a control unit disposed within the installation box. The installation box is located inside the isolation frame and between the mixed-flow inlet pipe and the rainwater drain pipe. When it is not raining, there is no water inside the isolation frame, the control unit does not work, the rainwater drain pipe outlet is closed, and the mixed-flow water is sewage, which is discharged from the sewage drain pipe below the installation box. When it rains, rainwater enters the interior of the isolation frame through the water quality judgment pipe, the control unit is activated, the sewage drain pipe at the bottom of the installation box is closed and the rainwater drain pipe outlet is opened, and the rainwater is discharged from the rainwater drain pipe into the rainwater well for collection, thus realizing the separation of rainwater and sewage.

[0005] While the aforementioned patent effectively addresses the problem of miscontrol caused by centralized sewage discharge, some rainwater in the water quality discrimination pipe directly enters the isolation frame and is discharged through the guide hole. This affects the rate at which the water level rises within the isolation frame, thereby affecting the sealing of the sewage discharge pipe and potentially causing some rainwater to be discharged from the sewage discharge pipe. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a building rainwater and sewage separation device that can overcome or at least partially solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A building stormwater and sewage separation device includes: a housing, and further includes: a cover disposed on the upper side of the housing; a bent plate fixedly disposed within the housing, with a first cavity and a second cavity respectively disposed on both sides of the bent plate; a water inlet pipe disposed on one side of the housing, and the water inlet pipe being connected to the second cavity; a sewage outlet disposed on the lower side of the housing, and the sewage outlet being connected to the second cavity; a discrimination pipe disposed on one side of the housing, and the discrimination pipe being connected to the first cavity; a drain outlet disposed on the bent plate; a drain outlet disposed on one side of the housing, and the drain outlet being connected to the second cavity, with a drain pipe disposed on the drain outlet; a first sealing component for sealing the sewage outlet and a second sealing component for sealing the drain outlet; a baffle rotatably disposed within the housing, and the baffle matching the discrimination pipe, with a magnetic block fixedly connected to the baffle, and the magnetic block being magnetically connected to the housing; when there is a certain water pressure in the discrimination pipe, the baffle opens.

[0009] To prevent the cover from closing, a first floating block is further provided on the cover.

[0010] To facilitate sealing the drain outlet, the first sealing assembly further includes a sealing rod that slides on the bending plate, and a plug matching the drain outlet is provided on the lower side of the sealing rod. A driving assembly for driving the sealing rod to move up and down is provided in the first cavity.

[0011] To facilitate the sliding of the sealing rod, the driving assembly further includes a support rod fixedly mounted on the bending plate, a driving plate rotatably mounted on the upper side of the support rod, a second floating block fixedly connected to one end of the driving plate, and a connecting plate symmetrically fixedly connected to the end of the driving plate away from the second floating block. A limiting groove is formed on the connecting plate, and a limiting rod is fixedly connected to the upper end of the sealing rod, with the diameter of the limiting rod being smaller than the diameter of the limiting groove.

[0012] To facilitate quick operation of the sealing rod, the distance between the sealing rod and the support rod is further reduced to the distance between the support rod and the second floating block.

[0013] To facilitate sealing the drain outlet, a connecting rod is fixedly connected to the sealing rod, and a baffle matching the drain outlet is fixedly connected to one end of the connecting rod.

[0014] Compared with the prior art, this utility model provides a rainwater and sewage separation device for buildings, which has the following beneficial effects:

[0015] 1. This building uses a rainwater and sewage separation device. In sunny weather, there is no water flow in the first chamber. At this time, the second floating block is at the bottom, the sewage outlet is open, and the drain outlet is closed. Domestic sewage enters the second chamber through the inlet pipe and is discharged from the sewage outlet. During rainy weather, rainwater enters and is stored in the separating pipe. When the water in the separating pipe reaches a certain level, the water pressure exceeds the magnetic attraction of the block. At this point, the cover rotates open, and water quickly enters the first chamber, causing the water level to rise instantly. The second floating block floats upward, moving the sealing rod downward. The plug then seals the sewage outlet, and the sealing rod moves the connecting rod downward, causing the baffle to slide downward, opening the drain outlet. Rainwater then enters the pipe network through the drain pipe, is collected in the separating pipe, and then instantly opens. This effectively reduces the time for sealing the sewage outlet and the time for opening the drain outlet, thus significantly improving the rainwater collection rate.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model effectively reduces the time for sealing the sewage outlet and the time for opening the drainage outlet by collecting rainwater in the discrimination tube and then opening it instantly, thereby effectively improving the rainwater collection rate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-5 A building stormwater and sewage separation device includes: a housing 1, and further includes: a cover 101 disposed on the upper side of the housing 1; a bent plate 106 fixedly disposed inside the housing 1, with a first cavity 107 and a second cavity 108 respectively disposed on both sides of the bent plate 106; a water inlet pipe 102 disposed on one side of the housing 1 and connected to the second cavity 108; a sewage outlet 105 disposed on the lower side of the housing 1 and connected to the second cavity 108; and a discrimination pipe 203 disposed on one side of the housing 1 and connected to the first cavity 107. The following components are connected: a drain outlet 109, located on a bending plate 106; a drain outlet 104, located on one side of the housing 1 and connected to the second cavity 108, with a drain pipe 103 installed on the drain outlet 104; a first sealing component for sealing the sewage outlet 105 and a second sealing component for sealing the drain outlet 104; a cover 2, rotatably installed inside the housing 1, matching the discrimination tube 203, with a magnetic block 202 fixedly connected to the cover 2, and the magnetic block 202 magnetically connected to the housing 1; and the cover 2 opens when there is a certain water pressure inside the discrimination tube 203.

[0025] The cover 2 is provided with a first floating block 201.

[0026] The first sealing assembly includes a sealing rod 3 that slides on the bending plate 106, and a plug 301 that matches the drain port 105 is provided on the lower side of the sealing rod 3. A drive assembly for driving the sealing rod 3 to move up and down is provided in the first cavity 107.

[0027] The drive assembly includes a support rod 305 fixedly mounted on the bending plate 106. A drive plate 306 is rotatably mounted on the upper side of the support rod 305. A second floating block 307 is fixedly connected to one end of the drive plate 306. A connecting plate 308 is symmetrically fixedly connected to the end of the drive plate 306 away from the second floating block 307. A limiting groove 309 is formed on the connecting plate 308. A limiting rod 302 is fixedly connected to the upper end of the sealing rod 3, and the diameter of the limiting rod 302 is smaller than the diameter of the limiting groove 309.

[0028] The distance between the sealing rod 3 and the support rod 305 is less than the distance between the support rod 305 and the second floating block 307.

[0029] A connecting rod 303 is fixedly connected to the sealing rod 3, and a baffle 304 matching the drain outlet 104 is fixedly connected to one end of the connecting rod 303.

[0030] During the process of separating rainwater and sewage in a building, when it is a sunny day, there is no water flow in the first cavity 107. At this time, the second floating block 307 is at the bottom, the sewage outlet 105 is open, and the drain outlet 104 is closed. Domestic sewage enters the second cavity 108 through the inlet pipe 102 and is discharged from the sewage outlet 105. When it rains, rainwater enters the distinguishing pipe 203 and is stored there. When the water in the distinguishing pipe 203 reaches a certain level, the water pressure exceeds the attraction of the magnetic block 202. At this time, the cover 2 rotates and opens, and the water in the distinguishing pipe 203 quickly... The water quickly enters the first cavity 107, causing the water level in the first cavity 107 to rise instantly. After the water level rises, the second floating block 307 floats upward, driving the sealing rod 3 to move downward. At this time, the plug 301 seals the drain outlet 105, and the sealing rod 3 drives the connecting rod 303 to move downward, causing the baffle 304 to slide downward. The drain outlet 104 is in the open state. At this time, rainwater enters the pipe network through the drain pipe 103, collects the rainwater through the discrimination pipe 203, and then opens instantly, thereby effectively reducing the time for sealing the drain outlet 105 and the time for opening the drain outlet 104, which can effectively improve the rainwater collection rate.

[0031] When the rain stops, the rainwater in the first cavity 107 is slowly discharged from the drain 109, and the second floating block 307 is reset.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
