[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model discloses a municipal engineering heating pipeline drainage device, including a drainage pipe, which includes a first drainage pipe 1 and a second drainage pipe 2. The first drainage pipe 1 and the second drainage pipe 2 are arranged vertically aligned. The top of the lower drainage pipe is provided with a water inlet head 3, which is flared. The size of the water inlet head 3 can be determined according to the actual use. The water receiving area at the top of the water inlet head 3 can be larger than the area of ​​the turntable 4. The water inlet head 3 serves to receive water and prevent water from flowing out when cleaning impurities, thus avoiding water waste.

[0028] A rotatable turntable 4 is installed at the bottom of the upper drain pipe 1. Several filter screens 6 for filtering impurities are detachably installed on the turntable 4. Rotating the turntable 4 allows the filter screens 6 to be switched. When the filter screens 6 are switched to a position that is not aligned with the drain pipe, the filter screens 6 can be removed, which facilitates the replacement of the filter screens 6 and also facilitates the cleaning of impurities.

[0029] The drain pipe and the turntable 4 are connected by a connecting block 8 and a connecting shaft 9. The connecting block 8 and the drain pipe are fixedly connected, while the turntable 4 and the connecting shaft 9 are rotatably connected.

[0030] Furthermore, it also includes a positioning component and a positioning groove 10 for positioning the turntable 4. The positioning component enters the positioning groove 10 to align the filter screen 6 and the drain pipe. The positioning component includes a connecting groove 11 set on the connecting block 8, a positioning block 12 installed at the opening end of the connecting groove 11, and a spring 13 installed in the connecting groove 11 to provide elastic force to the positioning block 12. When the turntable 4 is rotated, the positioning block 12 enters the positioning groove 10 to make the filter screen 6 and the drain pipe accurately aligned.

[0031] The turntable 4 has a mounting slot 5 for installing the filter screen 6.

[0032] The filter screen cover 6 has an edge 7 on its outer wall to prevent it from falling down from the mounting groove 5. The filter screen cover 6 can be removed by lifting it upwards, making it more convenient to use.

[0033] In summary, this municipal engineering heating pipeline drainage device, during use, uses a drain pipe to transport water into the pipeline, and the inlet head 3 serves to receive the water, preventing water from flowing out and wasting water when cleaning impurities. When cleaning impurities inside the filter screen 6, the turntable 4 is rotated to switch the filter screen 6. When the filter screen 6 is switched to a position that is not aligned with the drain pipe, the filter screen 6 can be removed, which facilitates the replacement of the filter screen 6 and also facilitates the cleaning of impurities.
