Description

Technical Field

[0001] This utility model relates to the field of building drainage technology, and more specifically, to a system for monitoring and clearing drainage blockages. Background Technology

[0002] The drainage system of multi-story residential buildings mainly consists of main risers and horizontal branch pipes. The horizontal branch pipes connect sanitary fixtures to the main riser, collecting wastewater from these fixtures and transporting it to the main riser, from where it flows downwards into the municipal sewage network. If a blockage occurs in the main riser and cannot be detected and cleared in time, sewage from the floor where the blockage occurs can backflow into the living areas of residents on higher floors, affecting their quality of life. Utility Model Content

[0003] In view of the problem in the prior art that when the main riser of the drainage system is blocked, it cannot be detected and cleared in time, which will lead to sewage backflow and affect the quality of life of residents, this utility model provides a drainage blockage monitoring and clearing system that can automatically detect and clear blockages and prevent sewage from backflowing to higher floors.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] A drainage blockage monitoring and unblocking system includes a main pipe, a first branch pipe, a water tank, a water level gauge, and a high-pressure pump. A first one-way valve is provided within the inner cavity of the main pipe, allowing fluid to flow only from the top to the bottom of the main pipe. One end of the first branch pipe is connected to one side of the main pipe and communicates with it. A detection chamber is provided within the water tank, and the first branch pipe communicates with the detection chamber. The water level gauge is located within the detection chamber. The high-pressure pump is electrically connected to the water level gauge.

[0006] The high-pressure pump mentioned above can be an air pump or a liquid pump.

[0007] In use, the top and bottom of the main pipe are connected to different main risers. When a blockage occurs in the drainage system below the first branch pipe, the water below the first check valve cannot flow upwards due to the valve's obstruction, and instead enters the detection chamber of the water tank through the first branch pipe. When the water level gauge detects that the water level in the detection chamber has reached a certain height, it indicates a blockage in the drainage system. At this time, the water level gauge triggers a high-pressure pump to apply fluid or gas pressure to the detection chamber. This fluid or gas pressure will then enter the main pipe through the first branch pipe to clear the blockage.

[0008] Preferably, the first one-way valve includes a valve body and a sealing part, the valve body and the sealing part being connected and forming a cavity between them. One end of the valve body is rotatably connected to the top side of the inner wall of the first branch pipe, and the rotation axis of the valve body is perpendicular to both the axis of the main pipe and the axis of the first branch pipe. In the initial state, at least part of the sealing part is located within the cavity of the main pipe at the point where the main pipe and the first branch pipe connect. When a blockage occurs in the drainage system below the first branch pipe, the water above the first one-way valve cannot continue to flow downwards, causing the water pressure on the float valve to decrease. At this time, the water pressure on the float valve and its own weight are insufficient to overcome the buoyancy of the sealing part, and the entire float valve will flip upwards until the sealing part is stuck in the main pipe, sealing the main pipe. After the blockage is cleared, the water above the first one-way valve can continue to flow downwards, and the float valve will return to its initial position under the action of water pressure.

[0009] Preferably, the valve body is a planar structure, and the sealing part is a spherical structure. Planar and spherical structures are easier to manufacture than other convex structures. The planar structure of the valve body prevents buoyancy from hindering the upward rotation of the first check valve, making it easier for the first check valve to rise. The spherical structure, compared to other shapes, reduces resistance during upward rotation and distributes pressure more evenly, thus making it easier for the first check valve to rise and remain stable in sewage.

[0010] Preferably, the inner wall of the first branch pipe is provided with a limiting rib, and in the initial state, the valve body abuts against the limiting rib. The limiting rib restricts the position of the entire first check valve by restricting the position of the valve body, preventing the first check valve from flipping into the first branch pipe and thus failing to perform its sealing function in time when the drainage system is blocked.

[0011] Preferably, the system further includes a second branch pipe, one end of which is connected to one side of the main pipe and communicates with it. The outlet end of the second branch pipe is not higher than the position of the first one-way valve when it blocks the main pipe. The second branch pipe can be used to connect to a horizontal branch pipe in a drainage system. In existing drainage systems, horizontal branch pipes connect sanitary fixtures and the main riser, responsible for collecting wastewater discharged from each sanitary fixture and transporting the wastewater to the main riser. The second branch pipe can be used to connect to a horizontal branch pipe in a drainage system.

[0012] Preferably, the second branch pipe is provided with a second one-way valve, which only allows fluid to flow from the second branch pipe into the inner cavity of the main pipe. This can prevent sewage in the main pipe from flowing back into the residential area through the second branch pipe, thereby further reducing the risk of sewage flowing back into the residential area.

[0013] Preferably, the second one-way valve includes a valve plate connected to the second branch pipe body. The fixed end of the valve plate is connected to the second branch pipe body, and the movable end of the valve plate extends downward from the top side of the second branch pipe body into the inner cavity of the main pipe body. It is understood that sewage flowing out of the second branch pipe body can open the valve plate, allowing sewage in the second branch pipe body to flow smoothly into the main pipe body, while sewage in the main pipe body cannot open the valve plate, preventing sewage in the main pipe body from flowing back into the second branch pipe body.

[0014] Preferably, the system further includes a sealing cover. The top side of the second branch pipe body is provided with an installation groove and a through groove. The installation groove communicates with the inner cavity of the second branch pipe body through the through groove. The top end of the valve piece is provided with an anti-detachment part, which is located within the installation groove and abuts against it. A retaining groove is formed between the anti-detachment part and the inner wall of the installation groove. At least a portion of the sealing cover is embedded in the retaining groove and fits against the entire inner wall of the retaining groove. When installing the valve piece, the valve piece can be passed through the through groove until the anti-detachment part abuts against the installation groove, and then the sealing cover is pressed tightly onto the retaining groove. The installation groove and through groove facilitate the installation and replacement of the valve piece, while the sealing cover improves the sealing of the installation groove and through groove, preventing sewage leakage.

[0015] Preferably, the axis of the first branch pipe forms an acute angle with the axis of the main pipe, and the end of the first branch pipe is higher than the end connected to the main pipe. That is, the first branch pipe is inclined upward, which can prevent sewage residue from remaining in the first branch pipe.

[0016] Preferably, the system also includes a trachet, with a vent on the first branch pipe body. The vent is connected to the detection chamber via the trachet. An end cap is threadedly connected to the end of the first branch pipe body. Wastewater inside the first branch pipe body can enter the detection chamber through the trachet, and high-pressure fluid or gas in the detection chamber can also enter the first branch pipe body through the trachet. The end cap at the end of the first branch pipe body allows operators to open it for inspection and maintenance when necessary.

[0017] The beneficial effects of this utility model are:

[0018] 1. A first check valve is installed in the main pipe to prevent sewage from flowing back up through the main pipe. The system also includes a first branch pipe, a water tank, a water level gauge, and a high-pressure pump. When the drainage system is blocked, sewage in the main pipe can flow into the water tank through the first branch pipe. When the water level in the tank reaches a certain height, the water level gauge will trigger the high-pressure pump to pump out pressure to clear the blockage. This achieves automatic monitoring and clearing of drainage system blockages, preventing sewage from flowing back up to higher floors and affecting the quality of life of residents.

[0019] 2. The first check valve adopts a special hollow structure and can rotate. When a blockage occurs in the drainage system below the first branch pipe, the first check valve can automatically rotate to block the main pipe, preventing sewage from flowing back to the upper floors through the main pipe.

[0020] 3. A second branch pipe is installed on the main pipe, and a second one-way valve is installed in the second branch pipe. Sewage in the second branch pipe can open the valve plate of the second one-way valve and enter the main pipe, while sewage in the main pipe cannot open the valve plate and enter the second branch pipe, which can further reduce the risk of sewage backflow into the residential area.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0030] Example 1

[0031] This embodiment is a first embodiment of a drainage blockage monitoring and unblocking system, combined with Figures 1 to 3 As shown, it includes a main pipe body 1, a first branch pipe body 2, a water tank 4, a water level gauge 5, and a high-pressure pump 6; the inner cavity of the main pipe body 1 is provided with a first one-way valve 3, which only allows fluid to flow from the top to the bottom of the main pipe body 1; one end of the first branch pipe body 2 is connected to one side of the main pipe body 1 and communicates with the main pipe body 1; the water tank 4 is provided with a detection chamber 401, the first branch pipe body 2 communicates with the detection chamber 401, and the water level gauge 5 is located in the detection chamber 401; the high-pressure pump 6 is electrically connected to the water level gauge 5.

[0032] Specifically, the high-pressure pump 6 mentioned above is an air pump.

[0033] Specifically, the water level gauge 5 is a float water level gauge, and when the water level gauge 5 rises to a certain height, the power supply of the high-pressure pump 6 can be turned on.

[0034] Furthermore, the axis of the first branch pipe 2 forms an acute angle with the axis of the main pipe 1, and the end of the first branch pipe 2 is higher than the end that connects to the main pipe 1. That is, the first branch pipe 2 is inclined upward, which can prevent sewage residue from remaining in the first branch pipe 2.

[0035] Furthermore, it also includes a tracheal tube 10, and the first branch tube 2 is provided with a vent 202, which is connected to the detection chamber 401 through the tracheal tube 10; an end cap 11 is threadedly connected to the end of the first branch tube 2. Wastewater in the first branch tube 2 can enter the detection chamber 401 through the tracheal tube 10, and high-pressure fluid or gas in the detection chamber 401 can also enter the first branch tube 2 through the tracheal tube 10. The end cap 11 is provided at the end of the first branch tube 2, and the operator can open the end cap 11 to inspect and maintain the inside of the first branch tube 2 when necessary.

[0036] Furthermore, it also includes a sealing ring 12, which is pressed between the end face of the first branch pipe body 2 and the end cap 11, and is used to improve the sealing performance of the end cap 11.

[0037] The working principle or workflow of this embodiment is as follows: In use, the top and bottom of the main pipe 1 are connected to different main risers 13. When a blockage occurs in the drainage system below the first branch pipe 2, the water below the first one-way valve 3 cannot flow upward due to the obstruction of the first one-way valve 3, but enters the detection chamber 401 of the water tank 4 through the first branch pipe 2 and the air pipe 10. When the water level gauge 5 detects that the water level in the detection chamber 401 has reached a certain height, it indicates that there is a blockage in the drainage system. At this time, the water level gauge 5 triggers the high-pressure pump 6 to apply gas pressure to the detection chamber 401. This gas pressure will enter the main pipe 1 through the air pipe 10 and the first branch pipe 2 to clear the blockage.

[0038] The beneficial effects of this embodiment are as follows: A first one-way valve is installed in the main pipe to prevent sewage from flowing back up through the main pipe; the system is also equipped with a first branch pipe, a water tank, a water level gauge, and a high-pressure pump. When the drainage system is blocked, sewage in the main pipe can flow into the water tank through the first branch pipe. When the water level in the water tank reaches a certain height, the water level gauge will trigger the high-pressure pump to pump out pressure to clear the blockage, thereby realizing automatic monitoring and automatic clearing of drainage system blockage, and preventing sewage from flowing back to the upper floors and affecting the quality of life of residents.

[0039] Example 2

[0040] This embodiment is a second embodiment of a drainage blockage monitoring and unblocking system. This embodiment is similar to embodiment 1, except that it combines... Figure 3 and Figure 4 As shown, the first one-way valve 3 includes a valve body 301 and a sealing part 302. The valve body 301 and the sealing part 302 are connected and form a cavity between them. One end of the valve body 301 is rotatably connected to the top side of the inner wall of the first branch pipe 2. The rotation axis of the valve body 301 is perpendicular to both the axis of the main pipe 1 and the axis of the first branch pipe 2. In the initial state, part of the sealing part 302 is located in the inner cavity of the main pipe 1 at the connection between the main pipe 1 and the first branch pipe 2. When a blockage occurs in the drainage system below the position of the first branch pipe 2, the water above the first one-way valve 3 cannot continue to flow downward, resulting in a decrease in the water pressure on the float valve. At this time, the water pressure and its own weight are insufficient to overcome the buoyancy of the sealing part 302, and the entire float valve will flip upward until the sealing part 302 is stuck in the main pipe 1 and blocks the main pipe 1. After the blockage is cleared, the water above the first one-way valve 3 can continue to flow downwards, and the float valve will return to its initial position under the pressure of the flowing water.

[0041] Furthermore, the valve body 301 has a planar structure, while the sealing part 302 has a spherical structure. Planar and spherical structures are easier to manufacture than other protruding shapes. The planar structure of the valve body 301 prevents buoyancy from hindering the upward rotation of the first check valve 3, making it easier for the first check valve 3 to rise. The spherical structure, compared to other shapes, reduces the resistance encountered when the first check valve 3 rotates upward and makes the pressure on the first check valve 3 more uniform, thus making it easier for the first check valve 3 to rise and remain stable in sewage.

[0042] Furthermore, a limiting rib 201 is provided on the inner wall of the first branch pipe body 2, and in the initial state, the valve body part 301 abuts against the limiting rib 201. The limiting rib 201 restricts the position of the entire first check valve 3 by restricting the position of the valve body part 301, so as to prevent the first check valve 3 from flipping into the first branch pipe body 2 and thus failing to play its sealing role in time when the drainage system is blocked.

[0043] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0044] Example 3

[0045] This embodiment is a third embodiment of a drainage blockage monitoring and unblocking system. This embodiment is similar to embodiment 2, except that it combines... Figures 2 to 5 As shown, a second branch pipe 7 is connected to one side of the main pipe 1. The second branch pipe 7 communicates with the main pipe 1, and its outlet end is not higher than the position of the first one-way valve 3 when it blocks the main pipe 1. The second branch pipe 7 can be used to connect to a horizontal branch pipe 14 in the drainage system. In the existing drainage system, the horizontal branch pipe 14 connects the sanitary fixtures and the main riser 13, and is responsible for collecting wastewater discharged from the sanitary fixtures and transporting the wastewater to the main riser 13. The second branch pipe 7 can be used to connect to the horizontal branch pipe 14 in the drainage system.

[0046] Furthermore, a second one-way valve 8 is provided inside the second branch pipe body 7. The second one-way valve 8 only allows fluid to flow from the second branch pipe body 7 into the inner cavity of the main pipe body 1. This can prevent sewage in the main pipe body 1 from flowing back into the residential area through the second branch pipe body 7, thereby further reducing the risk of sewage flowing back into the residential area.

[0047] Furthermore, the second one-way valve 8 includes a valve plate 801 connected to the second branch pipe body 7. The fixed end of the valve plate 801 is connected to the second branch pipe body 7, and the movable end of the valve plate 801 extends downward from the top side of the second branch pipe body 7 into the inner cavity of the main pipe body 1. It is understood that sewage flowing out of the second branch pipe body 7 can open the valve plate 801, allowing sewage in the second branch pipe body 7 to flow smoothly into the main pipe body 1, while sewage in the main pipe body 1 cannot open the valve plate 801, preventing sewage in the main pipe body 1 from flowing back into the second branch pipe body 7.

[0048] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.

[0049] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description, and it is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
