Abstract

The invention discloses a double-layer protective well lid. The double-layer protective well lid comprises a well lid body, wherein the well lid body comprises a base and a top cover, the base is of a cavity structure with two ends open, the inner side wall of the base is of a double-step structure, the two steps are the first step and the second step respectively from the bottom surface of the base, a protective net with through holes is arranged on the first step, the cavity of the base is covered with the protective net, a support used for supporting the protective net is further arranged on the first step, the protective net and the support are fixedly installed on the first step through fixing parts, the top cover is placed on the second step, and the cavity of the base is closed by the top cover. According to the double-layer protective well lid, due to the fact that the protective net is installed on the lower portion of the common sewer well lid, when the top cover is flushed open or stolen, pedestrians or vehicles can be prevented from falling into a well due to the arranged protective net, and the double-layer protective well lid plays a role in protection, and has the advantages of being simple in structure, ingenious in design, low in cost and especially applicable to sewers needing well lids.

Description

Double shielding well lid

Technical field

The present invention relates to a kind of well lid, be specifically related to a kind of double shielding well lid.

Background technology

Well lid is for hiding road or family's middle-deep well, preventing that people or object from falling.In urban construction, there are many places need to use well lid, as inspection shaft or functional wells such as sewer pipe, tap water, power cable and communication cables.These well heads are generally all located on road, and its well lid can be divided into metal well lid, high strength fibre cement concrete well lid, Resin man-hole cover etc. by material, and wherein irony well lid is in the majority, and part is cement concrete well lid.And irony well lid is because iron can be recycled, and it is high to reclaim price, therefore often occurs stolen mistake phenomenon, and the easy like this pedestrian of making falls into or vehicle falls in well, causes casualties and property loss; Have part well lid because the weight of casting is lighter, in the time there is great flood, well lid is easily washed open by flood, also easily causes casualties and property loss simultaneously.

At present for solving the problem of above-mentioned existence; the design of well lid is of all kinds; as the Chinese invention patent that application number is 201010580756.X has been introduced a kind of Multilayer protection built-in lockset well lid; it comprises base systems, jam plate system, lock system, key system; jam plate system and lock system are positioned in base systems, and key system is used for opening whole system.The lock system of this kind of well lid employing is more firm; can prevent well that well lid article (as optical cable) stolen or down-hole are stolen; but its structure is more complicated, and designed lock system, jam plate system and key system easily damage by pressure by passing vehicles or pedestrians, thereby lose protective effect.When the well cover for sewer that this kind of well lid can not solve lightweight is washed open by flood or well lid is stolen, cause casualties and the problem of property loss, and well cover for sewer often flows to foreign material, phenomenon results in blockage.Summary of the invention

For above-mentioned deficiency, even if technical problem to be solved by this invention is to provide that one well lid is washed open by flood or is stolen, also can effectively prevent that pedestrian from falling in well or vehicle falls in well, there is simple in structure, safe and reliable double shielding well lid.

For addressing the above problem, the present invention is achieved through the following technical solutions: double shielding well lid, comprise well lid body, described well lid body comprises base and top cover, described base is the hollow cavity structure of both ends open, it is step-like that the inside wall of base is twin-stage, described twin-stage step is respectively first order step from the bottom surface of base, second level step, first order step is provided with the catch net with through hole that the cavity of base is covered, on first order step, be also provided with to support the support of catch net, catch net and support are all installed on first order step by fixture, described top cover is placed on the step of the second level and by the cavity of base and covers.

In such scheme, described fixture can be screw, and for support and catch net are installed firmly, the number of described fixture is at least 3.

In such scheme, described support can be cross, oblique Y-shaped or Lv character form structure.

In such scheme, according to real life demand, described top cover can be circle or rectangle.

Advantage of the present invention is:

The present invention is provided with a catch net below common well cover for sewer, in the time that top cover is washed open by water or be stolen, can prevent that by the catch net being provided with pedestrian or vehicle from falling in well, plays a protective role; Catch net can also play filtration foreign material simultaneously, prevents the effect of sewer blockage.That this double shielding well lid has is simple in structure, design feature ingenious, with low cost, is specially adapted to install on the sewer of well lid.
