[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It is mainly water used in daily life. It contains a lot of organic matter and is relatively easy to treat. A water seal well is a safety liquid seal device installed on the sewage pipeline network in the factory area where there are flammable gases, flammable liquid vapors or oil stains. It prevents the spread of combustion and explosion along the sewage pipeline network. A water seal well is a type of safety liquid seal.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When installing the inlet pipe, the existing liquid seal device usually requires the use of auxiliary tools, which is cumbersome, time-consuming and labor-intensive, greatly reducing the convenience of the inlet pipe installation and increasing the labor intensity of the workers; 2. The existing water seal well lacks a fixing mechanism for the inlet pipe, which causes the inlet pipe to become misaligned or tilted due to aging after long-term use, thus greatly reducing the liquid seal effect of the water seal well and failing to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a safety liquid seal device for sewage pipe networks, to solve the problems mentioned in the background art, such as the need for auxiliary tools to assist in the installation of the inlet pipe in existing liquid seal devices, which significantly reduces the convenience of inlet pipe installation and increases the labor intensity of workers; and the lack of a fixing mechanism for the inlet pipe in existing water seal wells, which leads to misalignment or tilting of the inlet pipe due to aging, thus significantly reducing the liquid seal effect of the water seal well.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a safety liquid seal device for sewage pipe networks, including a shell assembly 1. The bottom end of one side of the shell assembly 1 is connected to one end of a connecting rod 2. The other end of the connecting rod 2 is provided with an arc-shaped retaining ring 3. An inlet pipe 4 is provided inside the arc-shaped retaining ring 3. A sealing plate 5 is provided outside the inlet pipe 4. An installation groove 6 is provided outside the sealing plate 5. A sealing ring 7 is provided inside the installation groove 6. Several limiting blocks 8 are provided on one side of the sealing plate 5. A groove 9 is provided at the top of one side of the shell assembly 1. Several limiting grooves 10 are provided on one side of the groove 9.

[0021] In this embodiment, as Figure 1 As shown, the outer casing assembly 1 includes a water seal well body 101, a plurality of threaded knobs 102 are provided on one side of the water seal well body 101, and an outlet pipe 103 is provided on the side of the water seal well body 101 away from the threaded knobs 102.

[0022] In this embodiment, as Figure 3 As shown, the threaded knob 102 and the limit block 8 are connected by a thread; this enables the rapid installation of the water seal well inlet pipe 4 for sewage pipe network, greatly improving the convenience of the inlet pipe 4 during installation, thereby reducing the labor intensity of the workers when installing the inlet pipe 4.

[0023] In this embodiment, as Figure 2 As shown, the arc-shaped retaining ring 3 and the inlet pipe 4 are connected by a snap-fit ​​structure; this limits and fixes the position of the inlet pipe 4, solving the problem of misalignment or tilting of the inlet pipe 4 after long-term use, thereby greatly improving the stability of the inlet pipe 4 during use, improving the liquid seal effect of the sewage pipe network, and thus meeting the requirements of the safety liquid seal device for sewage pipe networks.

[0024] In this embodiment, as Figure 4 As shown, the external dimensions of the sealing plate 5 and the internal dimensions of the groove 9 are consistent; this increases the sealing effect of the water seal well during use and prevents leakage during use.

[0025] In this embodiment, as Figure 2As shown, the arc-shaped retaining ring 3 is made of rubber; this increases the flexibility of the arc-shaped retaining ring 3 during use and prevents it from damaging the inlet pipe 4.

[0026] In this embodiment, as Figure 3 As shown, the external dimensions of the limiting block 8 and the internal dimensions of the limiting groove 10 are consistent; this increases the stability of the inlet pipe 4 during use and prevents the inlet pipe 4 from tilting during use.

[0027] The usage and advantages of this utility model: The working process of this safety liquid seal device for sewage pipe networks is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the main body 101 of the water seal well is installed in the designated position. When it is necessary to install the plate on the inlet pipe 4, the sealing plate 5 on the outside of the top of the inlet pipe 4 is inserted into the inside of the groove 9, and the four limiting blocks 8 are simultaneously inserted into the four limiting grooves 10 on the inside of the groove 9. The cooperation of the limiting blocks 8 and the limiting grooves 10 prevents the inlet pipe 4 from rotating during installation. The cooperation of the sealing plate 5 and the sealing ring 7 increases the sealing effect of the water seal well during use and prevents leakage. Then, the bottom of the inlet pipe 4 is snapped into the inside of the arc-shaped retaining ring 3. At this time, the snapping structure of the arc-shaped retaining ring 3 is used to achieve the positioning of the inlet pipe 4. By limiting and fixing the inlet pipe 4, the problem of misalignment or tilting caused by prolonged use is solved, thereby significantly improving the stability of the inlet pipe 4 during use and enhancing the liquid seal effect of the sewage pipe network. At this time, by rotating the threaded knob 102, the threaded knob 102 is engaged with the inside of the limiting block 8 under the threaded cooperation between the water seal well body 101 and the limiting block 8, forming a snap-fit ​​structure between the threaded knob 102 and the limiting block 8. This enables the rapid installation of the water seal well inlet pipe 4 for the sewage pipe network, greatly improving the convenience of the inlet pipe 4 during installation, thereby reducing the labor intensity of the workers when installing the inlet pipe 4, and thus meeting the requirements of the safety liquid seal device for the sewage pipe network.
