[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It can be seen that a rainwater sewage interception device includes a shell 1, a filter cartridge 2 is arranged in the shell 1, filter holes 3 are evenly distributed on the filter cartridge 2, a water inlet 4 is arranged above the side wall of the shell 1, an upper cover 5 and a lower cover 6 are respectively arranged at the upper and lower ends of the shell 1, the upper cover 5, the lower cover 6 and the filter cartridge 2 are cooperated and connected to form a structure in which the filter cartridge 2 rotates in the shell 1, a water outlet 7 is arranged at the bottom of the filter cartridge 2, and a sewage outlet 8 is arranged on the lower cover 6. Rainwater enters the shell 1 from the water inlet 4, is filtered by the filter cartridge 2 and is discharged from the water outlet 7, and the impurities intercepted by the filter cartridge 2 are discharged from the sewage outlet 8.

[0018] When the utility model is used in a specific way,

[0019] The device is connected to a rainwater collection system. The collected rainwater enters the housing 1 from the water inlet 4, is filtered by the filter cartridge 2, and is discharged from the water outlet 7 to enter the next process. Impurities in the rainwater are intercepted by the filter cartridge 2 and retained in the housing 1. The impurities can be discharged from the sewage outlet 8.

[0020] If impurities adhere to the outer wall of the filter cartridge 2, the shell 1 rotates the filter cartridge 2, and the centrifugal force generated can throw the impurities off the outer wall of the filter cartridge 2 and then discharge them from the sewage outlet 8, thereby ensuring the filtering performance of the filter cartridge 2 and reducing blockage, thereby successfully completing the rainwater collection and filtering work.

[0021] The shell 1 is threadedly connected to the upper cover 5 and the lower cover 6, and the filter cartridge 2 is crimped with the upper cover 5 and the lower cover 6. The lower cover 6 is first threadedly connected to the shell 1, and then the filter cartridge 2 is placed in the shell 1. The upper cover 5 is then used to fix the filter cartridge 2 inside the shell 1 to complete the overall installation. The filter cartridge 2 can rotate inside the shell 1, and the filter cartridge 2 and the upper cover 5 and the lower cover 6 are rotationally sealed. Rainwater needs to be filtered by the filter cartridge 2 before it can be discharged from the water outlet 7.

[0022] A rotating wheel 9 is provided at the upper end of the filter cartridge 2, and the filter cartridge 2 is operated by the rotating wheel 9. The structure of the rotating wheel 9 is similar to that of a ship's rudder, and can be grasped and rotated, thereby rotating the filter cartridge 2 to generate centrifugal force to throw impurities out of the outer wall of the filter cartridge 2.

[0023] A scraper 10 is provided inside the shell 1, and the scraper 10 is in contact with the outer wall of the filter cartridge 2. When some impurities have strong adhesion and are difficult to separate from the outer wall of the filter cartridge 2 under the action of centrifugal force, the scraper 10 can scrape them off the outer wall of the filter cartridge 2, and cooperate with the centrifugal force to remove the impurities outside the filter cartridge 2, and finally discharge them from the sewage outlet 8.

[0024] A cover 11 is provided on the drain outlet 8. During normal use, the cover 11 closes the drain outlet 8 to perform conventional rainwater collection and filtering. When the amount of dirt collected in the shell 1 is large and affects the filtering speed, the cover 11 is opened to discharge the dirt from the drain outlet 8.

[0025] Compared with the prior art, the utility model has the following beneficial effects: the traditional rainwater sewage interception device is a fixed structure, and the intercepted dirt and impurities can only be transferred by the action of water flow, and are easily attached to the filter holes and cause blockage. The present application adopts a rotating filter cartridge, which can rotate to generate centrifugal force so that the dirt and impurities are thrown away from the filter cartridge, thereby ensuring the permeability of the filter holes. At the same time, a scraper is arranged outside the filter cartridge, and after cooperating with each other, the dirt and impurities are discharged, thereby reducing the blockage of the filter holes, ensuring the filtering effect of rainwater, and facilitating the cleaning of impurities, which is easy to use.
