Safe municipal drainage well lid with floating warning function

Abstract

The invention discloses a safe municipal drainage well lid with a floating warning function, a floating piece is fixedly arranged on the lower end face of the well lid, the buoyancy of the combination of the floating piece and the well lid in water is larger than the total gravity of the combination of the well lid and the well lid, and a linear guide structure capable of moving up and down is arranged between the well lid and the side face of a drainage well, the buoyancy acting point of the floating piece and the gravity center of the well lid are located on the same vertical line, the well lid is provided with an avoiding hole, the floating body is provided with a warning piece, the upper end of the warning piece is located in the avoiding hole, and the upper end of the warning piece is slightly lower than the upper end face of the well lid in the non-waterflooding state. Even if flood disasters are caused by extreme weather, the well lid does not need to be manually opened, rapid drainage is achieved, safety warning is provided when ordinary people walk to the drainage well, people are prevented from being accidentally sucked into the well to be drowned, the drainage requirement when the flood disasters are caused by the extreme rainy weather can be met, and potential safety hazards are eliminated, and floating objects on the water surface can be effectively filtered and blocked.

Description

【Technical field】 [0001] The invention relates to the technical field of well covers, in particular to a well cover with a floating function. 【Background technique】 [0002] Many drainage wells will be set up in municipal roads, streets and communities where people live to drain rainwater in time. The drainage wells are vertically arranged and communicated with the main drainage pipes installed horizontally underground. The well circle is covered with a steel or cement manhole cover, and there are 2 to 4 water leakage holes on the cover body. In extreme weather such as heavy rain or waterfall rain, not only the drainage is not smooth, but the water surface will rise above the ground, and the water level will continue. Every year, there are many floods caused by extreme weather in many places. In such areas where floods are caused by extreme weather, in order to facilitate rapid drainage, people usually lift the manhole cover to achieve rapid drainage, so that in a short time...

Problems solved by technology

[0002] Many drainage wells will be set up in municipal roads, streets and communities where people live to drain rainwater in time. The drainage wells are vertically arranged and communicated with the main drainage pipes installed horizontally underground. The well circle is covered with a steel or cement manhole cover, and there are 2 to 4 water leakage holes on the cover body. In extreme weather such as heavy rain or waterfall rain, not only the drainage is not smooth, but the water surface will rise above the ground, and the water level will continue. Every year, there are many floods caused by extreme weather in many places. In such areas where floods are caused by extreme weather, in order to facilitate rapid drainage, people usually lift the manhole cover to achieve rapid drainage. In this way, in a short time It is necessary to organize a large number of young and middle-aged personnel to open and shift the well covers in the water one by one. During the operation, not only the labor intensity is high, but also the safety risk is extremely high. If you are not careful, you will be involved in the well and cause casualties

Even if the manhole cover can be opened for drainage at the first time to achieve the purpose of rapid drainage, but in the flood state, ordinary people walk to the drainage well because they cannot see the well hole under the water, and if they are not careful, they will be sucked into the well by the flood and cause drowning. At the same time, debris floating on the water surface will also be involved in the well hole. Large debris such as wooden poles, blocks, planks, and foam boards will be involved in the well, which will directly affect the drainage.

In short, the existing municipal manhole covers cannot adapt to the drainage requirements of extreme rainstorm weather, and when the drainage well is flooded, it cannot provide safety warnings for people passing by the drainage well. The safety hazard is large and cannot be ruled out in advance
