Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In this embodiment:

a coupling device for municipal sewage pipes, as shown in figure 1, comprising: the whole first body 1 and the second body 2 that are linked together with municipal sewage pipeline install connecting pipe 3 between the junction of first body 1 and second body 2, and first body 1 and second body 2 all are linked together through screw thread and connecting pipe 3.

Simultaneously, in order to prolong the life of connecting pipe 3, so the cover is equipped with sleeve pipe 4 in the outside of connecting pipe 3, and is provided with the buffer unit between connecting pipe 3 and sleeve pipe 4, and is concrete, the buffer unit by interior outer including: a sponge layer 31 attached to the outer side wall of the connecting pipe 3; and a foam layer 32 attached between the sponge layer 31 and the sleeve 4.

When the inside of first body 1 and second body 2 is piled up because of the debris that take in the sewage and subsides, and lead to pressure to increase to can cause connecting pipe 3 pressurized deformation easily, consequently need through set up sponge layer 31 and foam layer 32 in the space between connecting pipe 3 and sleeve pipe 4, and then reach the purpose of extension connecting pipe 3's life to a certain extent.

As shown in fig. 2, in order to prevent leakage at the connection point of the connection pipe 3 and the first pipe 1 and at the connection point of the connection pipe 3 and the second pipe 2, a fastening assembly is required to be additionally installed at the connection point of the connection pipe 3 and the first pipe 1 and at the connection point of the connection pipe 3 and the second pipe 2, specifically, the fastening assembly includes: an arc-shaped plate 5; and a bottom plate 6. Two arcs 5 press from both sides tight each other and install in the junction of connecting pipe 3 and first body 1 and with the junction of second body 2, simultaneously, the bottom of arc 5 is fixed mutually with bottom plate 6 through articulated mode. In addition, in order to further expand the adaptation range of the arc-shaped plates 5, the ends of the two arc-shaped plates 5 far away from the bottom plate 6 are fixed through bolts.

When the connecting pipe 3 is tightly clamped with the joint of the first pipe body 1 and the joint of the second pipe body 2, the arc plates 5 are aligned to the connecting positions, and then the opening and closing degrees of the two arc plates 5 are adjusted through the bolts, so that the arc plates are matched with the pipe diameter to be tightly clamped, and the application range of the fastening assembly can be effectively widened.

In addition, as shown in fig. 3, in order to collect the sewage flowing out from the connection portion between the connection pipe 3 and the first pipe 1 and the connection portion between the connection pipe and the second pipe 2, an annular groove 51 is formed in the inner side wall of the arc plate 5, and the length of the annular groove 51 is equal to the arc length of the arc plate 5. Meanwhile, the annular groove 51 is filled with an adsorption layer 511, and in the present embodiment, the adsorption layer 511 is specifically a silica gel layer having good water absorption and corrosion resistance.

In addition, since the bottom plate 6 is further provided with the bottom groove 61 so as to collect the sewage flowing out of the adsorption layer 511, the inflow of the sewage into the adjacent soil layer can be effectively reduced, and the purpose of protecting the surrounding environment can be achieved to a certain extent. In addition, for can effectually avoiding debris in first body 1 and the second body 2 to flow into adsorption layer 511 along with sewage, and then influence adsorption layer 511's life, consequently, install filter screen 512 in the notch department annular of ring channel 51.

When the pipeline is because of can not obtain the clearance for a long time and gather too much debris, sewage invades because of the inner space when flowing through the pipeline and accounts for, thereby can extrude the pipeline inner wall, and simultaneously, the junction is comparatively weak because of the pipeline, at this moment, sewage can follow the junction of first body 1 and connecting pipe 3, and flow out in the gap of the junction of second body 2 and connecting pipe 3, then flow to filter screen 512, the sewage after filter screen 512 flows into adsorbed layer 511 again and is adsorbed, flow into kerve 61 again after the bottom of two arcs 5 collects at last, and then can carry out effectual collection to sewage.

As shown in fig. 3, in order to widen the application range of the connection pipe 3, the entire opening at both ends of the connection pipe 3 is formed in a horn-like structure, and a plurality of male screw connection ports 33 having different diameters are opened at the opening end of the connection pipe 3. When sewage pipeline installation is required, the external threaded connection ports 33 with different diameters on the connecting pipe 3 can be correspondingly selected to be in threaded connection according to the diameters of the first pipe body 1 and the second pipe body 2.

In addition, in order to further improve the sealing performance at the joint of the connection pipe 3 and the first and second pipes 1 and 2, a seal 52 is further installed between the arc plate 5 and the first and second pipes 1 and 2, and in this embodiment, the seal 52 is a rubber ring having a good waterproof performance.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without contribution after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
