[0027] In the sewage treatment process, the gas lift reflux device is one of the key equipment to ensure the treatment effect. To ensure its normal operation, it is necessary to monitor the working status of the gas lift reflux pipeline in real time. At present, the junction boxes of the monitoring devices on the market have many problems such as complex structure, inconvenient installation, and poor durability. Specifically, the existing junction boxes mainly have the following problems:

[0028] 1) The material is not resistant to aging: The existing junction boxes are mainly made of ABS material, which is easily affected by environmental factors and ages during long-term use, resulting in a decrease in the performance of the junction box and a shortened service life.

[0029] 2) The shape is not convenient for installation: the existing junction boxes are mostly square in shape, which is difficult to install when opening holes on the pipe. It not only increases the complexity of installation, but also may cause unnecessary damage to the pipe.

[0030] 3) Large volume occupies pipe flow area: The existing junction box is relatively large in size. After installation, it will occupy a certain pipe flow area, affecting the flow capacity of the pipe, which may lead to reduced sewage treatment efficiency.

[0031] 4) Unsound installation: Existing junction boxes are usually installed with glue, which is not strong enough. Over time, the glue may age and fail, causing the junction box to fall off the pipe, posing a safety hazard to the sewage treatment system.

[0032] To solve the above problems, the embodiments of the present invention provide a junction box, a monitoring device, a gas lift reflux pipe and a sewage treatment system. The junction box, the monitoring device, the gas lift reflux device and the sewage treatment system of the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0033] Please refer to the figure, Figure 1A schematic diagram of the disassembly of a junction box 10 provided in the embodiment of the first aspect of the present disclosure. The embodiment of the first aspect of the present disclosure provides a junction box 10, which is used in a monitoring device for the water outlet of a gas lift return pipe, and the junction box 10 includes a cylindrical junction box 1, a locking nut 2 and a sealing cover 3. The cylindrical junction box 1 includes a main body 11 and a protrusion 12, and a thread is provided on the outer contour surface of the main body 11. The protrusion 12 is provided at one end of the main body 11, and the outer diameter of the protrusion 12 is larger than the outer diameter of the main body 11; the locking nut 2 is used for threaded connection with the main body 11; the inner contour surface of the sealing cover 3 is provided with a thread, and the sealing cover 3 is threadedly connected to one end of the main body 11 away from the protrusion 12. Optionally, the height of the cylindrical main body 11 is 50 mm and the outer diameter is 50 mm. The protrusion 12 protrudes 10 mm relative to the main body 11.

[0034] The present disclosure adopts a cylindrical junction box 1 as the main structure of the junction box 10. The cylindrical structure facilitates the opening of corresponding installation circular holes on the pipeline, reduces the difficulty of opening holes and installation, reduces damage to the pipeline, and improves installation efficiency. In addition, a protrusion 12 is provided. During installation, the protrusion 12 is arranged inside the pipeline, and a locking nut 2 is used to tighten and fix the outside of the pipeline to ensure a tight connection between the junction box 10 and the pipeline. Since the outer diameter of the protrusion 12 is larger than the outer diameter of the main body 11, that is, the outer diameter of the protrusion 12 is larger than the installation circular hole on the pipeline, the junction box 10 is restricted from moving in the direction outside the pipeline, and the locking nut 2 restricts the junction box 10 from moving in the direction inside the pipeline, so that the connection between the junction box 10 and the pipeline is sufficiently firm.

[0035] Please refer to Figure 1 and Figure 2 , Figure 2 A schematic cross-sectional view of a cylindrical junction box 1 of a junction box 10 provided as an embodiment of the first aspect of the present disclosure, in some optional embodiments, the main body 11 includes a cylindrical portion 111 and a partition portion 112, the partition portion 112 divides the inner cavity of the cylindrical portion 111 into a first area 113 close to the sealing cover 3 and a second area 114 close to the protrusion 12, the first area 113 is used to accommodate the cable assembly, and the second area 114 is used to accommodate the electrode assembly. The inner cavity of the cylindrical portion 111 is divided into functional areas by the partition portion 112 to ensure that the practicality of the product and the orderliness of the installation of the cable assembly and the electrode assembly are not violated. In addition, by rationally planning and utilizing the internal structure of the main body 11, the volume of the junction box 10 is greatly reduced, thereby reducing the problem of occupying the flow area of ​​the pipeline after installation, and ensuring that the flow capacity of the pipeline is not affected.

[0036] In some optional embodiments, a first mounting hole 112a is provided on the partition portion 112 to connect the first area 113 and the second area 114, and the first mounting hole 112a is used to install the electrode. The first mounting hole 112a is provided to facilitate the electrode to pass through the first mounting hole 112a to be electrically connected to the cable assembly located in the first area 113, and the first mounting hole 112a can also play a certain role in limiting the electrode.

[0037] In some optional embodiments, the partition portion 112 includes a central portion 112b and a surrounding portion 112c arranged around the central portion 112b. Along the direction from the first area 113 to the second area 114, the size of the central portion 112b is smaller than the size of the surrounding portion 112c, and the first mounting hole 112a is arranged in the surrounding portion 112c.

[0038] In these optional embodiments, the thickness of the central portion 112b is relatively small, so that the space between the first area 113 and the second area 114 is large enough to facilitate the installation and arrangement of the cable assembly and the electrode assembly, and the thickness of the surrounding portion 112c is greater than the thickness of the central portion 112b, which can improve the structural strength of the partition portion 112. In addition, the first mounting hole 112a is arranged in the surrounding portion 112c with a larger thickness, and the hole depth of the first mounting hole 112a is also relatively large, which can better protect and limit the electrode.

[0039] Please refer to Figure 3 , Figure 3 A cross-sectional schematic diagram of a sealing cover 3 of a junction box 10 provided in an embodiment of the first aspect of the present disclosure. In some optional embodiments, a penetrating second mounting hole 31 is provided on the sealing cover 3, and the second mounting hole 31 is used to install a cable waterproof connector to ensure the waterproof performance of the cable connection.

[0040] In some optional embodiments, the sealing cover 3 includes a receiving cavity 32 communicating with the second mounting hole 31, and the receiving cavity 32 is used to receive a sealing component, providing an additional waterproof sealing measure to ensure the waterproof performance of the junction box 10. Exemplarily, the sealing component includes a sealing gasket.

[0041] In some optional embodiments, at least one of the cylindrical junction box 1, the locking nut 2 and the sealing cover 3 is made of ASA plastic. ASA plastic has excellent weather resistance and anti-aging properties, and can significantly extend the service life of the junction box 10 and reduce the risk of performance degradation and damage caused by material aging. The cylindrical junction box 1, the locking nut 2 and the sealing cover 3 can all be made of ASA plastic, or they can be partially made of ASA plastic, for example, only the parts that are prone to aging or damage are made of ASA plastic.
