Description

Technical Field

[0001] This utility model relates to the field of drainage pipe network monitoring technology, specifically a comprehensive drainage pipe network monitoring system. Background Technology

[0002] With the development of urbanization in my country, the construction of municipal public facilities has developed rapidly. Now, underground drainage pipes are installed under urban roads. Drainage pipes refer to the system composed of pipes and channels that collect and discharge sewage, wastewater and rainwater and their ancillary facilities, including main pipes, branch pipes and pipes leading to treatment plants. The drainage pipes that are densely distributed throughout the city constitute the drainage pipe network.

[0003] Currently, the inspection of drainage pipe networks mainly relies on regular manual patrols. However, these patrols cannot provide real-time status information, and respond quickly to any anomalies. Meanwhile, with the rapid development of IoT technology, drainage pipe monitoring is increasingly adopting this approach. Specifically, level sensors monitor the liquid level in drainage pipes, and water quality sensors monitor the water quality. The data is then transmitted wirelessly to terminal devices. The proper functioning of the wireless data transmission module is crucial for timely acquisition of drainage pipe network status information using IoT technology. However, wireless data transmission modules installed in waterproof boxes require connection to an external antenna via signal cables. Over time, moisture can easily seep into the waterproof box through the wiring holes, affecting the normal operation of the wireless data transmission module. Utility Model Content

[0004] The purpose of this utility model is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide a comprehensive monitoring system for drainage pipe networks.

[0005] A comprehensive monitoring system for drainage pipe networks includes a manhole and a waterproof box. The manhole is connected to an upstream drainage pipe and a downstream drainage pipe. A sensor is installed at the bottom of the manhole. A first wireless data transmission module is installed inside the waterproof box. The first wireless data transmission module is used to connect to the sensor and to transmit the data monitored by the sensor to a second wireless data transmission module. The second wireless data transmission module is electrically connected to a data collector, and the data collector is connected to a server.

[0006] The waterproof box consists of a shell and a cover plate, which are fixed together by bolts. An annular groove is provided on the side of the shell near the cover plate, and a waterproof strip is installed in the annular groove. A wire-passing sleeve is provided on the side wall of the shell for wires to pass through. A waterproof partition is provided inside the shell, which is flush with the height of the shell. The waterproof partition is used to separate the wire-passing sleeve and the first wireless data transmission module. The space enclosed by the waterproof partition and the side wall of the shell is filled with desiccant.

[0007] A further option is that the sensor includes at least a liquid level sensor and a COD water quality monitoring sensor.

[0008] A further option is that the collector is a Type I collector or a Type II collector.

[0009] A further embodiment includes a female plug and a power adapter inside the housing. The female plug is inserted into the power adapter, and the end of the female plug away from the power adapter is connected to 220V AC power. The power adapter is used to convert 220V AC power into low-voltage DC power. The first wireless data transmission module is provided with wiring terminals, and the end of the power adapter away from the female plug is connected to the VCC and GND ports of the wiring terminals.

[0010] A further solution is that the first wireless data transmission module is connected to the sensor via a 4-core shielded cable, and the 4-core shielded cable is connected to the 485A, 485B, VCC and GND ports of the terminal block respectively.

[0011] A further embodiment is that an antenna is bonded to the outer surface of the waterproof box with glass glue, and the antenna is connected to the first wireless data transmission module via a signal line.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the cooperation of the first wireless data transmission module, the second wireless data transmission module, the collector and the server, the first wireless data transmission module can send the received monitoring data to the second wireless data transmission module through the wireless communication protocol. The collector then forwards the monitoring data received by the second wireless data transmission module to the server. The server can be connected to the display screen, so as to realize remote monitoring of the water level and water quality of the drainage network. Therefore, once an abnormal situation occurs in the drainage network, a rapid response can be made.

[0013] (2) Through the cooperation of the shell, cover plate, annular groove, waterproof strip, waterproof partition, wire sleeve and desiccant, when water vapor seeps in through the gap between the shielding wire and the wire sleeve, the desiccant can absorb the water vapor in time to prevent it from interfering with the normal operation of the first wireless data transmission module, female plug and power adapter in the waterproof box.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1-5 This utility model provides a comprehensive monitoring system for drainage pipe networks, including a manhole 1, with an upstream drainage pipe 2 and a downstream drainage pipe 3 connected to the bottom of the manhole 1. A sensor 4 is installed at the bottom of the manhole 1, including at least a liquid level sensor and a COD water quality monitoring sensor. The liquid level sensor can monitor the liquid level of the drainage pipe network in real time, and the COD water quality monitoring sensor can monitor the water quality of the drainage pipe network in real time; therefore, a rapid response can be made in the event of any abnormality.

[0023] A support frame 5 is installed on the ground near the inspection well 1, and a support plate 14 is fixedly connected to the upper end of the support frame 5. A waterproof box 6 is installed on the support plate 14, and the waterproof box 6 consists of a shell 61 and a cover plate 62. An annular groove 611 is opened on the side of the shell 61 near the cover plate 62, and a waterproof strip 612 is installed in the annular groove 611. After the shell 61 and the cover plate 62 are fixed together by bolts, the waterproof strip 612 can prevent rainwater from seeping into the waterproof box 6, thus playing a waterproof role. A first wireless data transmission module 9 is installed inside the waterproof box 6, and a wire threading sleeve 614 for wires to pass through is provided on the side wall of the shell 61; the wire threading sleeve 614 is screwed onto the shell 61. The housing 61 contains a waterproof partition 613 with a wire-passing hole. The partition 613 is flush with the housing 61 and separates the wire-passing sleeve 614 from the first wireless data transmission module 9. The space enclosed by the partition 613 and the side wall of the housing 61 is filled with a desiccant, which can be calcium oxide or aluminum oxide. The housing 61 also contains a female plug 7 and a power adapter 8. The female plug 7 is inserted into the power adapter 8, with the end of the female plug 7 away from the power adapter 8 connected to 220V AC power. The power adapter 8 converts the 220V AC power to low-voltage DC power. The first wireless data transmission module 9 has a terminal block 91, and the end of the power adapter 8 away from the female plug 7 is connected to the VCC and GND ports of the terminal block 91. In this embodiment, the first wireless data transmission module 9 is connected to the sensor 4 via a 4-core shielded wire. Specifically, the 4-core shielded wire passes through the cable sleeve 614 and the waterproof partition 613 in sequence and is connected to the terminal 91 on the first wireless data transmission module 9. When moisture seeps in through the gap between the shielded wire and the cable sleeve 614, the desiccant can absorb the moisture, thereby preventing the moisture from affecting the normal operation of the first wireless data transmission module 9, the female plug 7, and the power adapter 8 in the waterproof box 6.

[0024] It should be noted that the wiring terminal 91 on the first wireless data transmission module 9 includes four ports: 485A, 485B, VCC, and GND. When the first wireless data transmission module 9 is connected to the sensor 4 via a 4-core shielded cable, the yellow, blue, red, and black wires of the 4-core shielded cable are connected to the four ports: 485A, 485B, VCC, and GND, respectively. The yellow, blue, red, and black wires of the 4-core shielded cable represent the 485A line, 485B line, positive power supply line, and negative power supply line, respectively. At the same time, the end of the power adapter 8 away from the female plug 7 is connected to the VCC and GND ports of the wiring terminal 91. Therefore, the first wireless data transmission module 9 can both receive the data monitored by the sensor 4 and supply power to the sensor 4.

[0025] It should be noted that when the 4-core shielded cable and the external power cable are routed outside the waterproof box 6, they need to be encased in PVC pipe or galvanized pipe; the wiring should be horizontal and vertical.

[0026] An antenna 10 is bonded to the outer surface of the waterproof box 6 with silicone sealant. The antenna 10 is connected to the first wireless data transmission module 9 via a signal line. The first wireless data transmission module 9 communicates with the second wireless data transmission module 11 through the antenna 10.

[0027] The second wireless data transmission module 11 is electrically connected to a data collector 12, which can be a type I or type II data collector. The data collector 12 is connected to a server 13. In this way, the first wireless data transmission module 9 can send the received monitoring data to the second wireless data transmission module 11 via a wireless communication protocol. The data collector 12 then forwards the monitoring data received by the second wireless data transmission module 11 to the server 13. The server 13 can be connected to a display screen, thereby enabling remote monitoring of the water level and water quality of the drainage network.
