[0002] In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns (villages) to provide residents with paid or free public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls within the scope of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects. For example, various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (part outside the red line), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all fall within the scope of municipal engineering.

[0003] Municipal sewage generally needs to be filtered before discharge to prevent impurities in the sewage from clogging the sewage pipes. However, some sewage contains large debris that is difficult to handle, which can lead to clogging of the filter. After long-term use, a layer of silt or smaller impurities will adhere to the surface of the filter, which can also clog the filter over time, resulting in poor sewage filtration effect.

[0004] Therefore, a municipal sewage filtering device is needed to solve the problems in the prior art that large debris in sewage is inconvenient to handle and the filter screen is easily blocked due to attached silt. Utility Model Content

[0008] It should be noted in the scheme that the transmission mechanism includes a first bevel gear, the center of the first bevel gear is rotatably fixedly installed on the outer wall of the bottom end of the driving rod, and the outer wall of the first bevel gear is meshedly connected with a second bevel gear and a third bevel gear on both sides.

[0009] By rotating the first bevel gear, the second bevel gear and the third bevel gear can be driven to rotate, and the rotation directions of the second bevel gear and the third bevel gear are opposite, thereby achieving bidirectional rotation between the rotating member and the connecting rod, thereby more effectively cleaning the debris inside the sewage.

[0010] It is further worth mentioning that a rotating member is fixed at the center of the second bevel gear, and a plurality of second crushing members distributed in parallel are fixed on the outer wall of the rotating member.

[0011] It should be further explained that a connecting rod is fixed at the center of the third bevel gear, the connecting rod passes through the center of the second bevel gear and the rotating member, and a plurality of third crushing members distributed in parallel are fixed to the outer wall of the connecting rod.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

A servo motor 2 is fixed to the top of the sewage pipe 1, a driving rod 3 is fixed to the driving end of the servo motor 2, a plurality of first crushing members 4 distributed in parallel are fixedly installed on the outer wall of the driving rod 3, a filter screen 12 is arranged on the inner wall of the sewage pipe 1, a protective member 5 is fixed to one side of the top of the positioning block 13, and a transmission mechanism 6 is arranged inside the protective member 5.

[0024] The transmission mechanism 6 can mainly realize the simultaneous rotation of the rotating member 7 and the connecting rod 9, and further can realize the rotation of the second crushing member 8 and the third crushing member 10. The transmission mechanism 6 can also realize the bidirectional rotation between the second crushing member 8 and the third crushing member 10, thereby realizing better cleaning of the debris inside the sewage, thereby avoiding clogging of the filter screen 12.

[0025] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the transmission mechanism 6 includes a first bevel gear 61, the center of the first bevel gear 61 is rotatably fixedly installed on the outer wall of the bottom end of the driving rod 3, and the outer wall of the first bevel gear 61 is respectively meshed and connected with a second bevel gear 62 and a third bevel gear 63 on both sides.

[0026] By rotating the first bevel gear 61, the second bevel gear 62 and the third bevel gear 63 can be driven to rotate, and the rotation directions of the second bevel gear 62 and the third bevel gear 63 are opposite, thereby enabling the rotating member 7 and the connecting rod 9 to rotate in both directions, thereby more effectively cleaning the debris inside the sewage.

[0027] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that a rotating member 7 is fixed at the center of the second bevel gear 62 , and a plurality of second crushing members 8 distributed in parallel are fixed on the outer wall of the rotating member 7 .

[0028] This scheme has the following working process: by starting the servo motor 2, it can drive the driving rod 3 to rotate, thereby driving the first crushing member 4 to rotate. When the first crushing member 4 rotates, the floating objects in the sewage can be initially crushed, and the driving rod 3 can be used to drive the transmission mechanism 6 to operate, thereby driving the first bevel gear 61 to rotate. By rotating the first bevel gear 61, the second bevel gear 62 and the third bevel gear 63 can be driven to rotate at the same time, and the second bevel gear 62 and the third bevel gear 63 have opposite directions, so that the rotating member 7 and the second crushing member 8, the connecting rod 9 and the third crushing member 10 can rotate in both directions, thereby further cleaning the debris in the sewage, and while rotating the connecting rod 9, it can also drive the brush plate 11 to rotate, thereby cleaning the sludge on the surface of the filter screen 12, further preventing the filter screen 12 from being blocked, and improving the sewage treatment efficiency.

[0032] The brush plate 11 fits the surface of the filter screen 12, so that the sludge on the surface of the filter screen 12 can be cleaned, thereby preventing the sludge or smaller impurities inside the sewage pipe 1 from clogging the filter screen 12, thereby causing poor sewage drainage filtering effect.
