The invention discloses an inspection well opening warning device which comprises a fixing seat. A step hole communicating the upper end with the lower end is formed in the fixing seat, a clamping connection ring is connected in the step hole, an accommodating device is arranged at the center of the clamping connection ring and fixed on the clamping connection ring through a connecting rod, an accommodating cavity with the upper end open and the bottom closed is arranged at the center of the accommodating device, a guide block is arranged in the accommodating cavity, a spring is arranged between the bottom of the guide block and the bottom of the accommodating cavity, a supporting rod is arranged vertically at the center of the top of the guide block, a warning board is fixedly arranged at the top of the supporting rod, and width of the warning board is less than hole diameter of the accommodating cavity. The inspection well opening warning device is simple in structure, is movably clamped on an inspection well opening and is convenient to mount and demount; an inspection well cover covers above the inspection well opening warning device, and the warning board can jump out and protrude outside of the inspection well opening once the inspection well cover is taken down and has warning and prompting effect, so that safety of pedestrians and vehicles is guaranteed.
Description
technical field [0001] The invention relates to the field of municipal engineering, in particular to a warning device for inspection well mouths. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Called the inspection well, the inspection well mouth is usually flush with the ground. [0003] Because the inspection wells are all connected to the outside world, in order to prevent pedestrians or animals from falling into the inspection wells, people install covers at the mouths of the inspection wells to cover the inspection wells, so they are called inspection well covers. [0004] Inspection wells are generally located on the main road, and there are many pedestrians and vehicles walking on them every day. Therefore, the...
