Abstract
A waterproof and dustproof well lid comprises a base and an upper well lid body. A water and dust storage lid is further arranged at the position, located below the upper well lid body, inside the base, and the water and dust storage lid is provided with an inward concave space with the open top. The base is composed of a bottom ring and a vertical ring, wherein the bottom ring is wider than the vertical ring. A groove is formed in a step part located on the inner side of the bottom ring, and a protruding edge is arranged on the edge of the water and dust storage lid and buckled in the groove. Water and dust are stored in the water and dust storage lid through the arranged water and dust storage lid and removed in the overhaul process, and therefore water and dust are prevented from entering a vertical shaft. Furthermore, a buckled connecting structure is adopted between the water and dust storage lid and the base, then, the structure similar to a labyrinth is formed, water or dust is prevented from passing through the structure, and therefore the waterproof and dustproof effects are further improved. The waterproof and dustproof well lid is good in effect, the load bearing strength is not affected, the environment inside the vertical shaft is clean, and the waterproof and dustproof well lid is especially suitable for a communication field and other industries with high requirements.
Description
Technical field
The utility model relates to vertical shaft cover plate field, and is particularly a kind of for the water proof and dust proof well lid to waterproof and the dustproof occasion of having relatively high expectations.
Background technology
For waterproof and dustproof have relatively high expectations vertical shaft cover plate field, usually adopt the mode of similar plug to form sealing in the prior art, for example Chinese patent 201220063103.9 discloses a kind of Waterproof well cover, comprise well lid and well seat, be provided with a waterproofing course on the well lid outer circumference surface, waterproofing course can be selected rubber fastening band, rubber fastening band can adopt electric boiling plate sulfuration adhesion or cold-adhered to be fixed on the well lid outer circumference surface, this rubber fastening band has good elasticity, abrasion resistance, resistance to ag(e)ing and tear resistance, the adaptive deformation ability is strong.The problem that exists is, owing to have variable encapsulant between well lid and the well seat, connecting closely between well lid and the well seat behind the long-term pressurized, opens very difficult, and rubber fastening band for a long time, repeatedly also easily damage after the pressure-bearing, cause on the contrary leakage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of water proof and dust proof well lid, can guarantee to obtain better waterproof and dust-proof effect under the prerequisite of load bearing effect, and can not affect application life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of water proof and dust proof well lid, comprise base and upper well lid, in base, be positioned at well lid below also be provided with water and deposit dirt lid, water is deposited the interior concave space that the dirt lid has open-top.
Described base is made of wider foundation ring and narrower vertical circle, and the stage section that is positioned at the inboard, foundation ring is provided with groove, and the edge that water is deposited the dirt lid is provided with the lug edge, and lug is along being fastened in the groove.
The contact surface of described base and upper well lid is taper surface.
Described upper well lid is provided with the opening hole, and opening is provided with seal rubber plug in the hole.
Described upper well lid bottom is the arcuate bottom of projection.
Described water is deposited dirt lid inwall and is provided with handle.
The upper surface that described water is deposited dirt lid is provided with the diversion inclined-plane of indent.
Be positioned at the outer wall of base, be provided with a plurality of reinforcing ribs between foundation ring and the vertical circle.
A kind of water proof and dust proof well lid that the utility model provides is deposited the dirt lid by the water that arranges and is made water and dust be stored in water to deposit in the dirt lid, removing in maintenance process, thereby avoids water and dust to enter in the vertical shaft.Further, water is deposited and is adopted the syndeton that fastens between the dirt lid and bottom seat, forms the structure in similar labyrinth, avoids water or dust to pass through, and has further improved the water proof and dust proof effect.Water proof and dust proof of the present utility model is effective, and load bearing stength is unaffected, makes the environment in the vertical shaft clean and tidy, is particularly useful for the communications field, electric power transportation art etc. in the higher industry of environmental requirement in the vertical shaft.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall structure cross-sectional schematic.
Fig. 2 is the stereogram that water is deposited the dirt lid in the utility model.
Among the figure: base 1, upper well lid 2, water are deposited dirt lid 3, reinforcing rib 4, and taper surface 5, dirt chamber 7 is deposited on diversion inclined-plane 6, water, arcuate bottom 8, opening hole 9, seal rubber plug 10, handle 11, lug be along 12, groove 13, stage section 14, foundation ring 15, vertical circle 16.
The specific embodiment
In Fig. 1,2, a kind of water proof and dust proof well lid comprises base 1 and upper well lid 2, in base 1, be positioned at well lid 2 below also be provided with water and deposit dirt lid 3, water is deposited the waters that interior concave spaces that dirt lid 3 has open-top consist of and is deposited dirt chamber 7.Structure thus is stored in water from a small amount of water of upper well lid 2 seepages and dust and deposits dirt chamber 7, and can not enter in the vertical shaft, thereby guarantees the clean and tidy clean of environment in the vertical shaft, the occasion of having relatively high expectations be applicable to communicate by letter, electric power conveying industries etc.
Optimize as among Fig. 1, described base 1 is made of wider foundation ring 15 and narrower vertical circle 16, the stage section 14 that is positioned at 15 inboards, foundation ring is provided with groove 13, the edge that water is deposited dirt lid 3 is provided with lug along 12, lug is fastened in the groove 13 along 12.Structure thus, the cross section at the fastening place forms the structure in similar labyrinth, make water or dust be difficult to by.
Optimize as among Fig. 1, the contact surface of described base 1 and upper well lid 2 is taper surface 5.Structure has reduced water and the dust of coming in from seepage between base 1 and the upper well lid 2 as far as possible thus.
Optimize as among Fig. 1, described upper well lid 2 is provided with opening hole 9, is provided with seal rubber plug 10 in the opening hole 9.Structure in the situation that does not affect unlatching, has further reduced entering of water and dust thus.
Optimize as among Fig. 1, described upper well lid 2 bottoms be protruding arcuate bottom.Because the position at upper well lid 2 middle parts is stressed larger, adopts this structure under the prerequisite that does not affect intensity, has reduced the weight of whole upper well lid 2.
