Embodiment Construction

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] see figure 1 , 2 And 3, the anti-falling device for the inspection shaft includes a load-bearing protective cover 100 and three protective cover support frames 200 (also can be other multiple). Both the load-bearing protective cover 100 and the protective cover support frame 200 are made of reinforced plastic with added glass fiber, and its biggest feature is high tensile strength and good impact resistance. The tensile strength is >100MPa under the ISO527-1 standard, and the unnotched impact strength of the Charpy beam is >25Mpa under the ISO 179-1 mark. Its corrosion resistance is also quite excellent, and it can resist corrosion for a long time in a humid and turbid atmosphere. , Oxidation resistance, etc.

Abstract

The invention discloses an anti-falling device for an inspection well. The anti-falling device comprises a circular bearing protection cover and a plurality of protection cover supporting frames arranged on the periphery of the bearing protection cover, wherein the protection cover supporting frames are fixedly connected to the inner wall of an inspection well mouth circumferentially at equal intervals; each protection cover supporting frame comprises a supporting plane and a clamping groove located above the supporting plane and used for preventing the bearing protection cover from moving up and down; a convex edge part corresponding to the supporting plane and a notch part corresponding to an accommodating groove are arranged at the circumferential edge part of the bearing protection cover; a plurality of positioning grooves are formed at intervals in the upper surface of the convex edge part; and derotation and falling prevention clamping hooks corresponding to the positioning grooves are arranged on the protection cover supporting frames. According to the anti-falling device, under the condition that the inspection well cover is stolen or opened due to emergency water discharging, a pedestrian or an object can be effectively prevented from falling into the inspection well, and personal property loss is avoided.

Description

technical field [0001] The invention relates to an anti-falling device for an inspection well, which prevents pedestrians or objects from falling into the well from the mouth of the inspection well. Background technique [0002] Inspection wells are used at the turns, branches, drops, etc. of drainage pipes to facilitate inspection and dredging. The scientific name is inspection wells. In the same way, inspection wells for telecommunication cables and power cable inspection wells buried underground are also called inspection wells. [0003] The well head of inspection shaft is all provided with inspection shaft cover, and existing inspection shaft cover adopts cast iron to make mostly, because material has recycling value, is often stolen, and the loss situation is serious. In addition, when urban roads are flooded due to continuous heavy rain, people are used to opening the manhole cover in order to speed up drainage, and lose the entrance of the manhole cover, and acciden...
