Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering equipment, and in particular relates to a drainage pipe crossing device for municipal engineering. Background Art

[0002] Municipal engineering refers to municipal facility construction projects. Drainage pipes refer to systems composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Drainage pipes are indispensable projects in municipal engineering. Drainage pipes need to be connected and installed with drainage pipe crossing devices. For example, a municipal engineering drainage pipe crossing device is recorded in the Chinese patent application with application number CN202011541094.5. In this patent, a mesh bag is arranged under the cover to intercept and filter impurities in the water to avoid clogging the drainage pipe.

[0003] Existing crossing devices generally use a filtering structure similar to the mesh bag in the cited patent to filter impurities in the water. However, the ordinary single-layer filtering structure has a poor filtering effect and is prone to blockage of the filtering structure itself, thereby affecting the water leakage. Therefore, it is necessary to design a new crossing device to solve this problem. Utility Model Content

[0004] The utility model aims to provide a municipal engineering drainage pipe crossing device to solve the problems that the filtering effect of the filtering structure inside the existing crossing device proposed in the above background technology is poor and it is easy to be blocked.

[0006] Preferably, the filtering structure further comprises a baffle, and the baffle is fixed to the rear end of the connecting seat.

[0007] Preferably, the filtering structure further comprises a handle, and the handle is fixed on the top surface of the connecting seat.

[0008] Preferably, the filtering structure further comprises an inclined slot, and the inclined slot is inclined toward the filter.

[0009] Preferably, a water collecting trough is fixedly connected to the bottom of the top leakage hole, and the water collecting trough is a funnel-shaped structure, and the bottom end is aligned with the middle of the arc-shaped filter plate.

[0010] Preferably, a connecting assembly is provided between the top cover and the bottom frame, and the connecting assembly includes bolts, side strips and mounting holes, the bolts are threadedly connected between the top cover and the top of the bottom frame, the side strips are symmetrically fixed on both sides of the top cover, and the mounting holes are opened on the surface of the side strips.

[0011] Preferably, a support assembly is provided between the bottom end of the connecting seat and the bottom frame, and the support assembly includes a support plate, an insertion rod and a slot. The support plate is fixed on both sides of the inner wall of the bottom frame, the bottom end of the connecting seat overlaps the surface of the support plate, the insertion rod is fixed to the bottom surface of the bottom end of the connecting seat and inserted into the interior of the slot opened on the surface of the support plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the designed filtering structure, impurities in the water can be filtered. The water flows through the top leakage hole to the arc filter plate. Part of the water will flow directly through the bottom leakage hole, and the other part of the water together with the impurities will slide to the two sides of the arc filter plate and fall on the bottom of the connecting seat. The impurities are collected and concentrated at this position, and the residual water in the impurities will gradually seep out and flow down from the net. Through this double-layer filtering structure, solid-liquid separation can be completed more thoroughly, the filtering effect is improved, and the filtered impurities are concentrated and collected, which is not easy to cause blockage of the filtering structure itself.
