Air-bag-clamping-type anti-theft anti-surging well lid device

Abstract

The invention relates to an air-bag-clamping-type anti-theft anti-surging well lid device. An air bag (4) structure is arranged on the periphery of the side surface of a well lid body (1) and is matched with a clamping groove (14) form in the inner wall of an outer barrel body (2); when the well lid body (1) is arranged in the opening of the top part of the outer barrel body (2), a water swellingphenomenon in a well hole is detected through detection of a water-immersion sensor (8) which is hung on below the well lid body (1), so that inflation operation on the air bag (4) is triggered and controlled; the air bag (4) is swelled and fills the clamping groove (14), so that clamping is realized; meanwhile, the well lid body (1) structure which is of a non-stressed-spot structure is adopted,so that the well lid body is prevented from being opened at will from the outside, and an anti-theft effect is realized; besides, an electric-control lifting structure is designed, and through synchronous work control of each micro electric-control telescopic rod (11), the well lid body (1) is lifted from the inside for realizing opening of the well lid body (1); and the anti-theft effect of the well lid is improved.

Description

technical field [0001] The invention relates to an air bag clamping type anti-theft and anti-surge manhole cover device, which belongs to the technical field of manhole covers. Background technique [0002] Manhole covers are the most common municipal public facilities. They are used to cover various wellheads to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. With the continuous development of technology, All kinds of manhole covers emerge in endlessly, but no matter what kind of manhole covers, some basic problems are still not well resolved, such as the loss of manhole covers and the fact that the manhole covers will be pushed out by water when they are flooded. In the vacant state, pedestrians may fall into a trap without a well cover if they do not pay attention a little, and they may be injured or die; cars may fall into the tr...

With the continuous development of technology, All kinds of manhole covers emerge in endlessly, but no matter what kind of manhole covers, some basic problems are still not well resolved, such as the loss of manhole covers and the fact that the manhole covers will be pushed out by water when they are flooded. In the vacant state, pedestrians may fall into a trap without a well cover if they do not pay attention a little, and they may be injured or die; cars may fall into the trap, causing casualties; underground water pipes and communication facilities without a well cover may cause damage and loss. even bigger
