[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1 to Figure 2 As shown, an underground drainage pipe system with a low-cost automatic alarm device for drainage pipe blockage includes an underground drainage pipe 1, a shaft pipe 2, a water level detection module 3, an Internet of Things module 4 and an OA system. Among them, a plurality of shaft pipes 2 are arranged along the length direction of the underground drainage pipe 1 and are respectively detachably connected with the underground drainage pipe 1; each of the shaft pipes 2 is installed with the water level detection module 3 for detecting the water level in the shaft pipe 2; each of the shaft pipes 2 is provided with the Internet of Things module 4 electrically connected to the corresponding water level detection module 3; and the OA system is respectively connected with each of the Internet of Things modules 4 for data communication.

[0030] The underground drainage pipe system with a low-cost automatic alarm device for drainage pipe blockage is combined by arranging an underground drainage pipe 1, a shaft pipe fitting 2, a water level detection module 3, an Internet of Things module 4 and an OA system. A plurality of shaft pipe fittings 2 are connected at intervals in the length direction of the underground drainage pipe 1. A water level detection module 3 and an Internet of Things module 4 are correspondingly installed on each shaft pipe fitting 2. Each water level detection module 3 is used to regularly detect the water level in the corresponding shaft pipe fitting 2, and the daily water level information of the shaft pipe fitting 2 is fed back to the OA system through the Internet of Things module 4. When the underground drainage pipe 1 is blocked, the water level of the shaft pipe fitting 2 in the upstream direction of the blocked position is detected. When the water level rises, the water level detection module 3 triggers the alarm state, generates alarm detection information and sends an alarm feedback to the OA system through the Internet of Things module 4, so as to notify the staff and facilitate the staff to promptly troubleshoot and repair the location section of the blocked underground drainage pipe 1. With this arrangement, the staff can monitor the drainage status of each monitoring point through the OA system. When blockage occurs, the blockage point can be discovered in time, which speeds up the investigation and repair and reduces the cost of inspection personnel and material resources. At the same time, the structure is simple, and the structural parts used are mature and reliable. Most of them are common and easily available structures on the market, with low cost, which is more conducive to market promotion and application.

[0031] In this embodiment, preferably, the water level detection module 3 is a pressure level gauge or a float level gauge, which has a good water level detection function for the shaft pipe 2. When the water level detection module 3 is a float level gauge, the float level gauge is composed of a float, a plug rod, etc. The float level gauge is installed on the upper end of one side of the shaft pipe 2 through a connecting flange. The float floats on the liquid surface according to the principle of equal volume of the displaced liquid. When the liquid level in the shaft pipe 2 changes, the float also moves up and down. Due to the magnetic effect, the reed of the float level gauge is magnetically attracted, and the liquid surface position is changed into an electrical signal. The actual position of the liquid is digitally displayed through the display instrument. The float level gauge thus achieves long-distance detection and control of the liquid level, which is convenient for timely detection of the water level in the corresponding shaft pipe 2 and feedback of the daily water level information of the shaft pipe 2 to the OA system through the Internet of Things module 4, and in the event of blockage, timely feedback of the alarm detection information to the OA system through the Internet of Things module 4, so as to notify the staff and facilitate the staff to timely troubleshoot and repair the position section of the blocked underground drainage pipe 1. The float level gauge has the characteristics of simple structure, high structural stability and reliability, safe use, easy installation, easy maintenance and corrosion resistance. When the water level detection module 3 is a pressure level gauge, the pressure level gauge adopts the principle of static pressure measurement. When the liquid level transmitter is put into a certain depth of the shaft pipe 2, the pressure on the sensor facing the liquid surface is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ*g*H, and the pressure P is measured, where P: the pressure on the transmitter facing the liquid surface; ρ: the density of the measured liquid; g: the local gravity acceleration; Po: the atmospheric pressure on the liquid surface; H: the depth of the transmitter into the liquid can be obtained. The pressure level gauge has the characteristics of high reliability, long service life, easy installation, simple structure, economical and durable. More preferably, the pressure level gauge is a diffused silicon pressure sensor, which also has the characteristics of small size, light weight and high detection accuracy. Of course, the water level detection module 3 is not limited to the pressure level gauge and the float level gauge. Other types of water level detection modules 3 may also be used according to needs.

[0032] In this embodiment, the Internet of Things module 4 is a NB-IoT communication module or a Wifi communication module or a LoRa communication module or a 4G / 5G communication module. The structural parts are mature and reliable, and most of them are common and easily available structures on the market. They are low-cost and more conducive to market promotion and application.

[0033] In this embodiment, a pipe extension portion is provided on one side of the upper end of the vertical shaft water pipe; the Internet of Things module is installed in the pipe extension portion; one end of the water level detection module is installed in the pipe extension portion, and the other end is located in the vertical shaft water pipe.

[0034] The shaft pipe fitting 2 includes a shaft water pipe 21 and a concrete column 22; the concrete column 22 is a square column, and of course, other shapes can be used according to needs. The underground drainage pipe 1 is provided with a pipe connection portion 11 that is adapted to be embedded and connected with the lower end of the shaft water pipe 21 at the position corresponding to each shaft pipe fitting 2; each shaft water pipe 21 is sheathed with a concrete column 22 on the outer peripheral side; the shaft water pipe 21 has a pipe extension portion 211 on one side of the upper end; the Internet of Things module 4 is installed in the pipe extension portion 211; one end of the water level detection module 3 is installed in the pipe extension portion 211, and the other end is located in the shaft water pipe 21. The water level detection module 3 and the Internet of Things module 4 are installed through the pipe extension 211, which protects the water level detection module 3 and the Internet of Things module 4, and the structure is stable and reliable. Then, the concrete column 22 is wrapped on the outer peripheral side of the vertical shaft water pipe 21, which can protect the vertical shaft water pipe 21 as a whole, and the structural connection is more stable and reliable, and the positioning and installation of the vertical shaft water pipe 21 are convenient, so as to achieve the effect of convenient disassembly and assembly. In addition, the vertical shaft water pipe 21 and the concrete column 22 form a customized vertical shaft pipe 2, which is more conducive to construction, assembly, maintenance and replacement.

[0035] Of course, in addition to the pipe connection portion 11 being adapted and embedded in the detachable connection, the lower end of the shaft water pipe 21 can also be detachably connected to the bracket of the underground drainage pipe 1 by means of a clamp or bolts.

[0036] Preferably, at least one strip groove 221 extending from the upper end to the lower end of the concrete column 22 is provided on the circumference of the concrete column 22. By providing the strip groove 221 on the concrete column 22, there is an adjustment space, which is conducive to the assembly and placement of the vertical shaft pipe 2 as a whole.

[0037] In order to protect the interior of the shaft water pipe 21 and prevent foreign matter such as garbage from entering due to exposure, the top surface of the shaft water pipe 21 is lower than the top surface of the concrete column 22. This arrangement is conducive to installing a top cover, so as to protect the interior of the shaft water pipe 21.

[0038] In order to provide support and stability for the structure, a support seat 5 for supporting the lower end of each concrete column 22 is provided at the position of each concrete column 22 of the underground drainage pipe 1 .

[0039] In order to facilitate the stable power supply of the structure, the water level detection module 3 and the Internet of Things module 4 are powered by a battery module or a mains supply. The battery module can be a lithium battery module, which is energy-saving and environmentally friendly and has a long battery life.

[0040] It should be noted that the water level detection module 3, the Internet of Things module 4 and the OA system universal standard parts or parts known to those skilled in the art, their structures and principles are all known to those skilled in the art through technical manuals or conventional experimental methods. The specific implementation of this application may involve the use of software, but the software used is the most commonly used software by those skilled in the art, and is not within the scope of protection of the claims of this patent application. In addition, the OA system is an existing conventional structure, and the numbers in the drawings are not shown.

[0041] The working process of the utility model is:

[0042] When the non-underground drainage pipe 1 is blocked, each water level detection module 3 is used to regularly detect the water level in the corresponding vertical shaft pipe 2 and feed back the daily water level information of the vertical shaft pipe 2 to the OA system through the Internet of Things module 4.

[0043] When the underground drainage pipe 1 is blocked, the water level of the vertical shaft pipe 2 in the upstream direction of the blockage position rises, and the water level detection module 3 triggers the alarm state, generates alarm detection information and sends alarm feedback to the OA system through the Internet of Things module 4, so as to notify the staff and facilitate the staff to troubleshoot and repair the location section of the blocked underground drainage pipe 1 in time.

[0044] In summary, the embodiment of the utility model provides an underground drainage pipe system with a low-cost automatic alarm device for drainage pipe blockage. By configuring the underground drainage pipe system with a low-cost automatic alarm device for drainage pipe blockage, the staff can monitor the drainage conditions of each monitoring point through the OA system. When blockage occurs, the blockage point can be discovered in time, which speeds up the investigation and maintenance and reduces the cost of inspection personnel and material resources. At the same time, the structure is simple, and the structural parts used are mature and reliable. Most of them are common and easily available structures on the market, with low cost, which is more conducive to market promotion and application.

[0045] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
