A rectangular manhole cover on urban pavement that can pretreat food waste

Abstract

The invention discloses an urban road surface rectangular manhole cover capable of carrying out pretreating on kitchen waste, and relates to the technical field of manhole covers. The urban road surface rectangular manhole cover capable of carrying out pretreating on the kitchen waste comprises a manhole cover body, four connecting rods are fixedly connected to the four right-angle positions of the bottom of the manhole cover body, the bottom ends of the four connecting rods are fixedly connected with the four right-angle positions of the top of an inclined plate correspondingly, a water control mechanism and oil-water separation mechanisms are installed on the inclined plate, and the oil-water separation mechanisms are embedded in the top surface of the inclined plate in an equidistant array manner. According to the urban road surface rectangular manhole cover capable of carrying out pretreating on the kitchen waste, whether the kitchen waste is poured into the manhole cover body or not is detected through a vibration sensor, liquid in the kitchen waste can be effectively squeezed into the oil-water separation mechanisms when a squeezing plate moves in a reciprocating manner, andthe situations that the content of organic matter in sewage is increased and the sewage disposal cost is increased due to the fact that the kitchen waste is directly discharged into a drainage systemare avoided.

Description

technical field [0001] The invention relates to the technical field of inspection well covers, in particular to a rectangular inspection well cover on urban pavements that can pretreat kitchen waste. Background technique [0002] Manhole covers are very common in urban roads. As an indispensable part of the urban drainage system, manhole covers also cover a large area. Commonly used manhole covers can be roughly divided into circular manhole covers and rectangular manhole covers according to their shapes. The former is relatively larger. At the same time, the drainage holes are small, and the main purpose is to facilitate the maintenance personnel to enter the sewer for related work while draining the middle section of the road, while the drainage work on both sides of the road is completed through the rectangular manhole cover with a large surface area covered by the drainage holes. The shape of the manhole cover has a relatively high drainage efficiency, which can effectiv...

Problems solved by technology

However, due to the rapid development of the catering industry, some restaurants that have not signed a food waste recycling agreement often use the method of directly pouring food waste into the sewer for disposal. After the food waste is poured into the sewer through the manhole cover, it cannot be in a normal liquid state Discharged into the drainage system, it is easy to accumulate. Due to the large amount of water and organic matter contained in the kitchen waste, it only takes a few days to breed harmful bacteria and odor, which constitutes a threat to the environment around the manhole cover and the health of residents. serious threat
