Technical Field

The invention relates to a sewer well cover, in particular to a multifunctional well cover assembly.

Background

In cities, sewer manhole covers are visible anywhere on roads, squares and the like, and in heavy rain, the manhole covers need to be opened in order to discharge rainwater in time. The operation has the following defects that manual operation is needed for opening the well lid, but workers cannot easily find the well lid at night and the like; if the manhole cover is opened, there is no warning structure, so there is a danger that passerby or vehicle may get into when driving; for another example, after the rainwater is drained, the worker is required to close the well cover again, so that the labor capacity of the worker is increased.

Disclosure of Invention

The multifunctional well lid assembly aims to overcome the defects of the traditional technology, can effectively solve the technical problems, does not need manual operation, and is suitable for popularization and application.

The aim of the invention is achieved by the following technical measures: the utility model provides a multifunctional well lid assembly, includes support frame and apron, the apron is circular, the apron is provided with water hole and second under the first hole, the support frame includes the base, the fixed solid fixed cylinder that is provided with in base bottom, gu fixed cylinder bottom is provided with the delivery port, slidable mounting has the flotation pontoon in the fixed cylinder, the fixed bracing piece that is provided with in flotation pontoon top, apron and bracing piece swing joint, gu fixed cylinder top is provided with the crossbeam, bracing piece and crossbeam sliding connection, the crossbeam is provided with guider, guider corresponds the setting with the apron.

The sewer well cover is suitable for being installed on the ground of a square with a clean environment, the support frame is located below the ground during installation, and the base is flush with the ground.

Through the above arrangement, when raining, the water flow enters the fixed cylinder through the first water outlet hole, the water level in the fixed cylinder rises when the water flow does not flow out, then the buoy rises, the buoy drives the cover plate to rise, the cover plate rises in the process, the cover plate can stand and is vertical to the base, the cover plate is striking at the moment, and pedestrians can find out remotely conveniently. The back is opened to the apron, the rainwater of being convenient for discharges, stops the drainage at heavy rain and accomplishes the back, and the flotation pontoon gliding, apron whereabouts in-process again receives guider effect, can slowly incline during the whereabouts, and the return after contacting the base at last, this process need not personnel's operation, can lap or closed operation according to the rainwater size is automatic, uses manpower sparingly.

As a preferred scheme, the guiding device comprises an upright post vertically arranged on the cross beam, a triangular block is arranged at the top of the upright post, and when the cover plate moves along the cross beam through the supporting column, the bottom edge of the cover plate slides along the top surface of the triangular block.

Through the arrangement, when the cover plate falls, the bottom of the cover plate can be in contact with the top surface of the triangular block, when the cover plate continues to slide downwards, the bottom of the cover plate moves obliquely along the top surface of the triangular block, finally, the side wall of the cover plate is in contact with the inner wall of the base, and the buoy falls into the mounting seat completely to the bottommost rear cover plate of the fixed cylinder.

As an optimal scheme, base bottom lateral wall evenly is provided with many fixed columns, the fixed cylinder lateral wall is provided with the pillar, the one end and the fixed column fixed connection of fixed cylinder are kept away from to the pillar.
