Description

Technical Field

[0001] This invention relates to sewer anti-clogging technology, and in particular to an intelligent alarm system for sewer pipe blockage. Background Technology

[0002] With the increasing prevalence of high-rise residential buildings, the drainage pipes in these buildings are at a very high risk of blockage due to the large number of residents and frequent use, especially the main drainage pipes below the ground floor units. Once blocked, if not detected in time, a large amount of sewage can back up into the residents' homes, causing significant disruption to their lives and resulting in property damage. Often, such blockages are difficult to detect promptly, such as at night or during the day when no one is home. By the time the blockage is discovered, the home may already be overflowing with sewage. Even if someone is home when the blockage occurs and it is discovered, it takes time for repair personnel to arrive and unclog the blockage, and by then, a large amount of sewage may have already backed up into the residents' homes, causing adverse effects.

[0003] Publicly available technologies also include sewer anti-clogging designs, such as patent publication number CN105714920B, which describes a sewer overflow and blockage alarm device. This device includes an alarm system and a pipe clearing system. The pipe clearing system includes a tee reducer, a tee pipe, a first butterfly valve, a second butterfly valve, a horn fitting, and a ball valve. The alarm system includes an overflow cylinder, a support base, a float, a float rod, a sleeve, an overflow pipe, a slammer, a limit switch, and a remote alarm. However, this device faces difficulties in practical application and may not achieve the desired alarm effect. Firstly, it requires a large installation at the inspection point, occupying significant space. Secondly, sewage often contains debris, easily clogging the tee reducer and preventing continued operation. Thirdly, after prolonged use, the first and second butterfly valves can easily become stuck, making them impossible to open in case of blockage. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of the impact of residential sewer pipe blockage on residents' lives and property damage, and to provide a smart alarm system for sewer pipe blockage, which has the features of remote and local alarm and emergency drainage when the sewer pipes in high-rise buildings are blocked.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: a smart alarm system for sewer blockage, including an overflow pipe connected to the sewer pipe, characterized in that the interface between the overflow pipe and the sewer pipe is located above the connection point between the lowest water point drain pipe and the sewer pipe in the building; a connecting pipe is provided in the overflow pipe, and two non-connected metal contacts are provided in the connecting pipe, the two metal contacts extend out of the connecting pipe and are connected to a local alarm through an alarm line, the local alarm being connected to the main unit of the smart alarm system for sewer blockage; the overflow pipe is connected downward to the sewer drain well of the building after passing through the connecting pipe.

[0006] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, after the overflow pipe is connected to the sewer pipe, a horizontal section is first set up, then a vertical section is set up upwards, and then it is connected downwards to the sewage well of the building's sewer pipe, with the connecting pipe located at the section of the vertical pipe.

[0007] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the highest point of the overflow pipe is lower than the height of the lowest overflow outlet of the water supply point in the building.

[0008] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the on-site alarm includes an alarm body, which is equipped with an audible and visual alarm and is connected to a local power supply.

[0009] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the alarm device body is equipped with a switch button, an inspection button, and a reset button, and is connected to the main unit of the intelligent alarm system for blocked sewer pipes via a communication line.

[0010] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the alarm system host includes a host body, which is equipped with a host display screen and a host control area, and is connected to a local power supply.

[0011] In the aforementioned intelligent alarm system for sewer pipe blockage, preferably, the host display screen includes information on inspection and blockage location, and the host control area includes a switch, remote fault inspection, and an alarm buzzer.

[0012] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the intersection of the overflow pipe and the sewer pipe is equipped with a protective net; the connecting pipe section is equipped with a detachable inspection cover.

[0013] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the wiring conduit includes a main wiring pipe, and a wiring protection pipe is provided radially along the main wiring pipe. The wiring protection pipe seals the metal contacts in the main wiring pipe, and the alarm wire is sealed and led out from the wiring protection pipe.

[0014] In the aforementioned intelligent alarm system for blocked sewer pipes, preferably, the two non-connected metal contacts are rigid bodies.

[0015] This technical solution addresses the problem of unpredictable sewer blockages in high-rise residential buildings, which severely impact residents' lives. Utilizing the building's existing sewer system, an overflow pipe is installed at the lowest water usage point. Its interface is located appropriately above the connection point between the drain pipe and the sewer line. When the blockage point is higher than this interface but does not reach the overflow level of the lowest indoor water usage point (such as a sink drain or toilet drain), the device in the overflow pipe will trigger an alarm, alerting management personnel to address the issue promptly.

[0016] This overflow pipe solution has multiple functions: it not only embeds alarm system contacts to alert managers to promptly detect and address blockages, but also serves as an emergency drainage system during blockages. As long as wastewater continuously flows through the metal contacts, the alarm system will sound an alarm continuously.

[0017] The alarm system consists of two unconnected metal contacts. These contacts are made conductive by the electrical conductivity of wastewater. The contacts are located in the connecting conduit of the overflow pipe. The overflow pipe is designed as follows: a horizontal section is first constructed, then a vertical section rises upwards, and finally bends downwards to connect to the building's sewer manhole. The connecting conduit is located within the vertical section. Therefore, under normal drainage conditions, the presence of wastewater in the horizontal section will not trigger the alarm. Only in a blocked state, when wastewater flows down the vertical pipe and submerges the two metal contacts, will the alarm immediately sound. Two scenarios may occur: First, a sudden surge in wastewater flow may cause the metal contacts to connect due to the impact force. This is an occasional event, and once the wastewater flows away, the contacts will naturally disconnect, and the alarm will automatically deactivate. Second, a genuine blockage may occur, in which case the two metal contacts will remain conductive, resulting in a continuous alarm.

[0018] The two metal contacts of this device are completely enclosed in the wiring conduit and then extend out of the conduit to the local alarm via an alarm line. The local alarm is then connected to the main unit of the intelligent alarm system for sewer blockage, enabling local and remote blockage alarm management.

[0019] This system can manage and prevent congestion in a community or a certain area. The location information of congestion points in the entire area can be intuitively viewed through the main display screen of the alarm system host.

[0020] This device can be equipped with various inspection windows and removable inspection covers at the connection pipe sections to facilitate device maintenance. Removable unblocking mechanisms are also installed at easily clogged sections of the corresponding drainage pipes.

[0021] In addition, a protective net is installed at the intersection of the overflow pipe and the sewer pipe to effectively prevent large debris from entering the overflow pipe; the two metal contacts have a certain rigidity and are coated with a nano-coating to prevent dirt from sticking to them and affecting the conductivity, thus maintaining the alarm sensitivity.

[0022] Compared with the prior art, the beneficial effects of the present invention are: it solves the problem that existing sewer pipe blockages have no prior alarm or cannot be alarmed, and provides a technical solution that can detect pipe blockages in a timely manner and use overflow pipes to achieve emergency drainage, avoiding the phenomenon that traditional sewer pipe blockages cannot be detected in time, resulting in sewage backflow into households causing property damage and affecting living conditions. It also has the characteristics of remote and local dual alarm and convenient and quick pipe dredging. Attached Figure Description

[0030] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0031] This embodiment describes an intelligent alarm system for drain pipe blockage, targeting the lower section of the building's drain pipe 7 that is prone to blockage. Figure 1 As shown, the system includes an overflow pipe 1 connected to the drain pipe 7. A section of wiring pipe 2 is provided in the overflow pipe 1. Two non-connected metal contacts 23 are arranged in the wiring pipe 2. The two metal contacts extend out of the wiring pipe 2 and are connected to the local alarm 3 through the alarm line 5. The local alarm 3 is connected to the main unit 4 of the intelligent alarm system for drain pipe blockage.

[0032] Specifically, the interface between the overflow pipe 1 and the sewer pipe 7 is located above the connection point between the lowest water usage point drain pipe 8 and the sewer pipe 7 in the building. After the overflow pipe 1 connects to the sewer pipe 7, a horizontal section is first installed, followed by an upward vertical section. Then, after passing the highest point, it bends downwards, and a horizontal section is installed before connecting to the sewage well of the building's sewer system. The connecting pipe 2 is located in the vertical section. The highest point of the overflow pipe 1 is lower than the height of the lowest overflow outlet of the water usage point in the building, generally located below the lowest water usage point, such as a water tank.

[0033] Wiring pipe 2 includes a main wiring pipe 21, such as Figure 2 , Figure 3 As shown, a wiring protection tube 22 is provided radially along the main wiring pipe 21. The wiring protection tube 22 seals the metal contacts 23 within the main wiring pipe 21. The alarm wire 5 is sealed and led out from the wiring protection tube 22 to the field alarm 3. The metal contacts 23 are made of a highly rigid conductive material. The two metal contacts 23 are initially parallel from the fixing point of the wiring protection tube 22 and then bend outwards to improve the structural strength of the contacts.

[0034] 3-on-site alarm device Figure 4 As shown, the system includes an alarm body 31, which contains an audible and visual alarm 32 and is connected to a domestic power supply. The alarm body 31 is equipped with a switch button 311, an inspection button 312, and a reset button 313, and is connected to the main unit 4 of the intelligent alarm system for drain pipe blockage via a communication line 6. The on-site alarm 3 is connected to a domestic power supply via a first power plug.

[0035] The intelligent alarm system for blocked sewer pipes includes the main unit 41, see [link / reference]. Figure 5 The system host 41 is equipped with a host display screen 42 and a host control area 43, and is connected to a domestic power supply via a second power plug 44. The host display screen 42 displays inspection and blockage location information, and the host control area 43 includes a switch, remote fault inspection, and an alarm buzzer.

[0036] Figure 6 This is the electrical control schematic diagram of this embodiment, which is a conventional circuit application and will not be described in detail here.

[0037] In addition, the connecting pipe section 2 is equipped with a removable inspection cover and a transparent observation port for easy on-site maintenance and daily management. The intersection of the overflow pipe 1 and the drain pipe 7 is equipped with a corrosion-resistant mesh to prevent large pieces of waste from entering and clogging the overflow pipe 1. Furthermore, the horizontal section of the overflow pipe 1 forms a 5-20 degree angle with the horizontal line, further preventing waste flushed down from above the drain pipe 7 from accumulating at the interface.

[0038] When used with this device, a detachable unblocking mechanism, such as a mechanical unblocking rod, a high-pressure water tap, or an air gun, can be installed at the corresponding easily clogged parts of the sewer pipes.

[0039] The working principle of the intelligent alarm system for blocked sewer pipes in this embodiment is as follows: When the sewer pipe 7 in a residential building is blocked, the water level in the sewer pipe will rise continuously, and sewage will backflow into the overflow pipe 1. When the water level exceeds the two metal contacts 23 in the connecting pipe 2, the two metal contacts 23, which were originally not connected, will connect due to the conductivity of sewage. This will form an electrical path with the on-site alarm 3 through the alarm line 5, thereby triggering the on-site alarm. Sound and light alarm signals will be emitted at the location of the blockage in the building to alert the residents. Simultaneously, the address information of the on-site alarm 3 will be transmitted via the communication line 6 to the main unit 4 of the intelligent alarm system for blocked sewer pipes installed in the property management office. The main unit will display the relevant blockage location information on its screen and emit a buzzer signal to alert the on-duty personnel. The on-duty personnel can immediately obtain information based on the alarm signal, locate the blockage location, and dispatch maintenance personnel to repair and unclog it. Simultaneously with the alarm, because the highest point of the overflow pipe 1 is lower than the height of the drain outlet in the resident's home, emergency drainage can be carried out through the overflow pipe 1 once the sewage level exceeds the highest point of the overflow pipe 1. When the sewage volume is not particularly large, the sewage will not overflow into residents' homes. The system can simultaneously perform alarm and emergency drainage, providing local and remote blockage alarms, emergency drainage, and preventing sewage backflow. This reduces the impact of sewer blockage on residents and avoids significant property damage.

[0040] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. In the field of sewer anti-clogging technology, any simple modifications to the structure or method of the present invention are within the protection scope of the present invention.
