Blockage-preventing inspection well lid

Abstract

The invention belongs to the field of urban construction and particularly relates to a blockage-preventing inspection well lid. The blockage-preventing inspection well lid comprises a well lid body, wherein the upper end of the well lid body is provided with a round groove, vertically communicated water draining channels are uniformly formed around the round groove, an arc-shaped elastic plate isarranged at the upper end of the round groove, a fixing rod is fixedly connected to the bottom side wall of the round groove and is sleeved with a first spring and a sleeve, the upper end and the lower end of the first spring are fixedly connected with the sleeve and the bottom side wall of the round groove, the upper end of the sleeve is fixedly connected with the lower end of the arc-shaped elastic plate, the sleeve is externally in sleeved connection with a compressing plate matched with the rough groove, an air compressing chamber is formed between the compressing plate and the round groove, an air exhausting channel communicated with the water draining channels is formed in the side wall of the round groove, a control mechanism is arranged in the air exhausting channel, multiple air inlet channels are arranged at the bottom of the round groove, and a first one-way valve is arranged in each air inlet channel. The blockage-preventing inspection well lid can automatically clean the water draining channels in the inspection well lid and prevent the blockage situation of the inspection well lid.

Description

technical field [0001] The invention belongs to the field of municipal construction, in particular to an anti-clogging inspection well cover. 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, so a cover is needed to cover the inspection well, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. On the inspection well cover, it is generally necessary to indicate the purpose of the underground pipeline, the management unit and telephone number. [0003] During daily use, the drainage hole of t...

Problems solved by technology

[0005] The existing anti-clogging manhole cover has the following disadvantages: the rotating wheel body and the side wall of the water channel are connected through the rotating shaft, and when the wheels of the car are in contact with the rotating wheel body, it is easy to slip; and when the weight of the car itself is too heavy (such as muck trucks, etc.), relying entirely on the weight of the rotating shaft, the rotating shaft is easily damaged, and the service life is short; The end surface of the wheel body is not only easy to cause damage to the rotating wheel body, but cannot produce the effect of rotating and cleaning, but also causes greater damage to the wheel
