Description

Technical Field

[0001] The utility model belongs to the technical field of manhole covers, and in particular relates to a sewer odor-proof manhole cover. Background Art

[0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures and equipment that are set up within the planning and construction scope of urban areas and towns to provide residents with paid or free public products and services based on government responsibilities and obligations. Sewers are a type of urban public facility, which refers to the pipes that buildings use to remove sewage and rainwater. In order to seal the top opening of the sewer, corresponding manhole covers are required.

[0003] Existing manhole covers for municipal projects are generally provided with ventilation holes, but they do not have the function of preventing odor. Gas from the sewer will drift through the ventilation holes, affecting the living environment of residents. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a sewer odor-proof manhole cover to solve the problem that the existing municipal engineering manhole covers are generally provided with air holes but do not have an odor-proof function, and the gas in the sewer will drift through the air holes, affecting the living environment of residents.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a sewer odor-proof manhole cover, comprising a manhole cover, a manhole body is fixedly installed at the bottom end of the manhole cover, a diversion cavity is provided at the top of the well body, and a diversion box is fixedly installed below the diversion cavity, a floating plate is slidably installed inside the diversion box, and a sliding rod is fixedly installed at the center of the bottom end of the floating plate, the sliding rod passes through the center of the bottom end of the diversion box and is slidably connected thereto, and an extrusion plate is fixedly installed at the bottom end of the sliding rod, and the extrusion plate is connected to a movable component, an installation groove is opened at the center of the top end of the manhole cover, and limiting slots are opened at opposite positions of the inner walls on both sides of the installation groove, the limiting slots are connected to the splitting components, the splitting components are installed inside the mounting seat, and the mounting seat is fixedly installed at both ends of the filter screen plate.

[0006] The beneficial effects of the utility model are:

[0007] During use of the device, the filtered rainwater flows into the diversion cavity through the water permeable hole 1, and then flows into the diversion box through the diversion cavity. When the rainwater in the diversion box receives an appropriate amount of water, the excess water can flow into the cavity in the guide plate through the water permeable hole 3, and finally the rainwater is discharged through the guide plate. The remaining filtered rainwater in the diversion box can cause the floating plate to block the water permeable hole 3 to prevent odor from flowing into the diversion cavity and floating above the manhole cover.

[0008] When rainwater flows into the diversion box through the diversion cavity, and the rainwater flows into the diversion box through several water-permeable holes opened at the top of the floating plate, the rainwater makes the floating plate float upward, and the sliding rod drives the squeezing plate upward, the upward-moving squeezing plate squeezes the sensor, and when the sensor is squeezed, it sends a start signal to the electric telescopic plate, so that the electric telescopic plate drives the baffle plate downward to expose the bottom end of the guide plate, thereby discharging the rainwater, and when the rainwater in the diversion box is discharged to the appropriate amount of water, the floating plate moves downward, and at this time the squeezing plate is separated from the squeezing of the sensor, and the electric telescopic plate receives the signal, which causes the electric telescopic plate to drive the baffle plate upward, thereby blocking the bottom end of the guide plate, and the blocked guide plate can prevent odor from emanating upward.

[0009] In order to discharge the filtered rainwater into the well:

[0010] As a further improvement of the above technical solution: the bottom end of the installation groove passes through the bottom end of the manhole cover and is provided with a plurality of water permeable holes.

[0011] The beneficial effect of this improvement is that a water-permeable hole is provided to discharge the filtered rainwater into the well body.

At this time, the card block is disengaged from the engagement connection with the limit card slot, and the filter screen plate can be taken out of the installation slot for disassembly and replacement. When installing the filter screen plate, the filter screen plate can be directly engaged in the installation slot. At this time, the inclined surface of the card block will slide into the telescopic cavity when it is squeezed. When the mounting seat is engaged in a suitable position, the card block will slide into the limit card slot through the elastic potential energy of the spring without external force extrusion, thereby installing the filter screen plate.

[0015] In order to make the block slide into the telescopic cavity:

[0016] As a further improvement of the above technical solution: the bottom end of the block is arranged as an inclined surface.

[0017] The beneficial effect of this improvement is that when the filter screen plate is inserted into the installation groove, the inclined surface is squeezed at the edge of the installation groove so that the block can slide into the telescopic cavity.

[0018] In order to block the water hole three:

[0019] As a further improvement of the above technical solution: a plurality of water-permeable holes three are opened through the top of the inner walls on both sides of the diversion box, guide plates are fixedly installed on both sides of the diversion box, and a cavity is opened in the guide plate, and the cavity passes through the bottom end of the guide plate, and the water-permeable holes three are connected to the cavity.

[0020] The beneficial effect of this improvement is that during the use of this device, the filtered rainwater flows into the diversion chamber through the water permeable hole one, and then flows into the diversion box through the diversion chamber, and when the rainwater in the diversion box receives an appropriate amount of water, the excess water can flow into the cavity in the guide plate through the water permeable hole three, and finally the rainwater is discharged through the guide plate, and the remaining filtered rainwater in the diversion box can cause the floating plate to block the water permeable hole three to prevent odor from flowing into the diversion chamber and floating above the manhole cover.
