Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage pipe intercepting device. Background Art

[0002] Currently, most cities have a combined sewer system. For old urban areas or urban villages that do not have the conditions for rainwater and sewage diversion in the system and need to intercept sewage, it is necessary to separate clean and sewage. It is necessary to control the discharge of sewage into the surface water environment and municipal rainwater pipes, and at the same time, it is also necessary to control the entry of surface water such as rivers and lakes into the sewage system.

[0003] Chinese patent CN112012316A discloses a rainwater outlet designed to intercept both initial rainwater and domestic sewage during sunny periods. The outlet opens and closes the sewage connection pipe by means of a spring that contracts and moves the baffle as the amount of rainwater collected and drained from the drain cup changes. However, the spring is prone to rust and failure in long-term humid environments, making it impossible to achieve effective sewage separation. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0016] like Figure 1 As shown, a sewage pipe intercepting device includes a connecting pipe 1, with an inlet pipe 10 and an outlet pipe 9 provided on both sides of the connecting pipe. This design allows sewage to enter the connecting pipe through the inlet pipe, and then be intercepted or discharged to the outlet pipe as needed, thereby achieving effective control of sewage. A closed box 2 is provided on the top of the connecting pipe, which provides protection for the internal mechanical structure and is convenient for maintenance and inspection. A guide block 6 is provided in the closed box, and a guide groove is provided on the guide block. The guide groove passes through the guide block and is connected to the connecting pipe. A cylinder 3 is provided on the inner wall of the closed box, and a telescopic rod 4 of the cylinder passes through the closed box and is connected to a blocking plate 5, which cooperates with the guide groove. The telescopic movement of the cylinder drives the blocking plate to move, thereby achieving rapid and reliable blocking of the connecting pipe.

[0017] The solution is refined, and the blocking plate can block the connecting pipe to limit the connection between the water inlet pipe and the water outlet pipe. This design enables the device to effectively prevent the flow of sewage when needed, meeting the requirements of clean and dirty water diversion.

[0018] Furthermore, the inner wall of the enclosure is provided with a plurality of heating plates 7, and in conjunction with this, an air vent 8 is provided at the top of the enclosure. The heating plates reduce the humidity within the enclosure, preventing mechanical components from rusting or failing, and extending the life of the device. The air vent ensures that moisture can be discharged smoothly, further improving the reliability of the device.

[0019] Furthermore, a one-way valve is provided at the air outlet, which allows moisture in the closed box to be discharged to the outside. The design of the one-way valve prevents external moisture or impurities from entering the closed box, ensuring a clean and dry internal environment.

[0020] In at least one embodiment, the outlet pipe end is provided with a right flange 91, the inlet pipe end is provided with a left flange 101, and the inlet pipe, connecting pipe, and outlet pipe are fixedly connected together by bolts 11 and nuts 12. This connection method is simple and firm, ensuring the stability and safety of the device during operation.

[0021] In some embodiments, a humidity sensor is provided within the enclosure, coupled to the heating element. The humidity sensor can monitor the humidity within the enclosure in real time and control the activation and deactivation of the heating element as needed, thereby achieving intelligent humidity control and further improving the reliability and service life of the device.

[0022] To operate, first install the sewage pipe interception device at the desired interception location, ensuring that the inlet pipe 10 is connected to the sewage source and the outlet pipe 9 is connected to the downstream sewage pipe or treatment facility. Use bolts 11 and nuts 12 to securely connect the inlet pipe, connecting pipe 1, and outlet pipe, ensuring a tight seal at the joints. Check the fit of the blocking plate 5 within the guide groove to ensure it can smoothly move within the guide groove to block or open the connecting pipe. Adjust the initial position of the cylinder 3 as needed to ensure the blocking plate 5 is in the appropriate blocking or opening position. If a humidity sensor is included in the enclosure, ensure it is properly connected to the heating plate 7 and set the appropriate humidity threshold. During rainy days or when sewage interception is required, control the telescopic rod 4 of the cylinder 3 to move the blocking plate 5 to the blocking position, preventing sewage from flowing through the connecting pipe to the outlet pipe 9, thereby intercepting the sewage. When sewage needs to be discharged, control the cylinder 3 to move the blocking plate 5 to the open position, allowing sewage to flow through the connecting pipe to the outlet pipe 9.

[0023] Regularly check the working condition of the cylinder 3, sealing plate 5, and guide groove to ensure their flexibility and reliability. Observe the humidity inside the enclosure. If the humidity is too high, the heating plate 7 will automatically activate to reduce the humidity and prevent rust and failure of related components. At the same time, the one-way valve ensures that the moisture inside the enclosure can be smoothly discharged to the outside.

[0024] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
