Abstract
The utility model provides an anti-falling device of an inspection well cover. The anti-falling device comprises a water permeable cover and connection plates, wherein the outer diameter of the water permeable cover is attached to the inner wall of an inspection well and arranged below the inspection well cover, the water permeable cover is at least connected with two connection plates, each connection plate is provided with a screw hole, and the connection plates are fixed to the side wall of the inspection well. The anti-falling device of the inspection well cover is simple and reasonable in structure and convenient to use, what is needed is to place the anti-falling device under an existing inspection cover and fix the anti-falling device to the side wall of the inspection wall through expansion screws, the anti-falling device can effectively support weight of a person who falls into the inspection well and impact force when the person falls into the inspection well accidentally, and fortuitous casualty caused by loss or damage of the inspection well cover is avoided.
Description
Technical field
The utility model relates to well lid manufacturing technology field, particularly a kind of inspection well cover fall-proofing device.
Background technology
Along with economic, social fast development, on road, various inspection shafts are more and more, comprise the maintenance inspection shaft of drainage system, electrical cable, and the inspection shaft of the equipment such as communication network and coal gas.Inspection well cover commonly used consists of Moveable lid body and the lining be fixed on road surface, and Moveable lid body can be opened or close, and identical smooth with road surface, guarantees the unimpeded of pedestrian, vehicle.This type of inspection well cover generally is made of cast iron, and has the advantages that anti-impact force is strong, but cast iron itself has higher economic worth, often becomes the object that the undesirable steals; More particularly be positioned at the inspection well cover of remote position, often stolen and be difficult to redistribute in time installation, form dangerous to pedestrian and driving.In addition, because the inspection well cover quality problems are damaged by pressure by vehicle, do not repair in time or change; Or open the inspection well cover draining and forget and cover back; These do not cover or uncap that to forget that situation about again resetting all forms pedestrian or driving dangerous, often have vehicle to be absorbed in the accident that inspection shaft or pedestrian fall in well and occur, and have become urban construction and have been badly in need of the significant problem solved.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art; a kind of inspection well cover fall-proofing device simple in structure, easy to use is provided; this device has the advantages that to protect to greatest extent pedestrian, traffic safety, can be widely used on all kinds of inspection shafts.
The inspection well cover fall-proofing device that the utility model embodiment provides is arranged at the catch pit port under inspection well cover, comprises permeable lid and junction plate; The external diameter of described permeable lid and the inwall of inspection shaft fit, and are arranged at the inspection well cover below; Described permeable covering at least is connected with two described junction plates, on described junction plate, is provided with screw, and described junction plate is fixed on the sidewall of described inspection shaft.
Wherein, described permeable lid is tabular, is provided with permeable hole on it, adopts high-strength material to make, and as Kev, draws wherein one or more such as spacing, carbon fiber, polyurethane sheet or glass fiber to make.
Wherein, adopt chain connection between described permeable lid and at least one described junction plate.
Wherein, described junction plate Central Symmetry is distributed in the outer edge of described permeable lid.
Wherein, described permeable lid is made by resistant material.
Wherein, described permeable lid is made by stainless steel material.
Wherein, the outside of described permeable lid scribbles self-luminescent material, for the night when well lid is lost, can remind timely the pedestrian to avoid well lid.
The inspection well cover fall-proofing device that the utility model provides, simple and reasonable, easy to use, only need transfer and be fixed in the inspection shaft sidewall by swell fixture and get final product at existing inspection well cover, can when personnel's contingency is fallen into inspection shaft accidentally, effectively support the person's of falling into weight and impact force, avoid the personnel's fortuitous casualty because inspection well cover is lost or damage causes.In addition, the permeable lid of this inspection well cover fall-proofing device is made by the rigid material of certain intensity, and manufacturing process is simple, and can not be out of shape because of long-term the use, closely is fixed on the inspection well cover inwall, has improved application life, has wide market prospects.
The accompanying drawing explanation
The structural representation of the inspection well cover fall-proofing device that Fig. 1 is the utility model embodiment;
The installation generalized section of the inspection well cover fall-proofing device that Fig. 2 is the utility model embodiment.
[description of reference numerals]
1: junction plate; 2: permeable lid; 3: swell fixture.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, 2: the inspection well cover fall-proofing device of the present embodiment comprises permeable lid 1 and junction plate 2; The external diameter of permeable lid 1 and the inwall of inspection shaft fit, and are arranged at the inspection well cover below; At least be connected with two junction plates 2 on permeable lid 1, the present embodiment adopts two junction plates, the junction plate Central Symmetry is distributed in the outer edge of described permeable lid, on junction plate 2, is provided with screw, and junction plate 2 is fixed on the sidewall of inspection shaft through screw by swell fixture 3.Permeable lid 1 is tabular, be provided with a plurality of permeable holes on it, generally adopt high-strength material to make, make as Kev draws wherein one or more such as spacing, carbon fiber, polyurethane sheet or glass fiber, in the situation that cost allows, permeable lid 2 also can directly adopt stainless steel material to make.
As shown in Figure 2, between permeable lid 1 and one of them junction plate 2, adopt chain connection, after another junction plate 2 is fixed in the inspection shaft sidewall, with permeable lid 1 be directly bonding relation.Can be easy for installation and removal like this, can be installed on easily and effectively in existing inspection shaft.The outside of permeable lid 1 scribbles self-luminescent material, for the night when well lid is lost, can remind timely the pedestrian to avoid well lid.
The inspection well cover fall-proofing device that the utility model provides, simple and reasonable, easy to use, only need transfer and be fixed in the inspection shaft sidewall by swell fixture and get final product at existing inspection well cover, can when personnel's contingency is fallen into inspection shaft accidentally, effectively support the person's of falling into weight and impact force, avoid the personnel's fortuitous casualty because inspection well cover is lost or damage causes.In addition, the permeable lid of this inspection well cover fall-proofing device is made by the rigid material of certain intensity, and manufacturing process is simple, and can not be out of shape because of long-term the use, closely is fixed on the inspection well cover inwall, has improved application life, has wide market prospects.And the outside of permeable lid scribbles self-luminescent material, for the night when well lid is lost, can remind timely the pedestrian to avoid well lid.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
