Abstract
The utility model discloses a maintenance manhole cover for water and pollution prevention, which comprises a round cover plate. The utility model is characterized in that the utility model also comprises a round frame positioned at the lower part of the round cover plate, and a rubber sealing ring. The circumferential edge of the round frame is provided with an upward and annular bulge, and the lower side of the round cover plate is provided with a downward and annular bulge corresponding to the annular bulge. The outside diameter of the annular bulge of the cover plate is slightly smaller than the inside diameter of the annular bulge of the round frame, and the rubber sealing ring is arranged between the two annular bulges. The manhole cover can effectively prevent liquid, filth, etc. from invading into a manhole chamber. The utility model has the advantages of convenient operation, low cost, good water and pollution prevention effect, etc.
Description
The utility model relates to the urban operating mechanism field, relates in particular to a kind of maintenance type well lid.
Existing general well lid only has load-bearing and antitheft function, and does not possess the waterproof anti-fouling functions, prevents that promptly the liquid (as rainwater) of well lid ground surface and dirts such as the silt intrusion well that liquid is carried secretly are indoor, causes the many dirts of the indoor savings of well.Particularly whole well chamber will take place flood season in rainwater, and dirt infiltrates the well chamber in a large number, has had a strong impact on the normal use of safeguarding well; Particularly may cause serious consequence to combustion gas, electric power, communication, this phenomenon of water supply well.Because well chamber itself do not possess independently drainage system, safeguard often cleaning pollutant of well chamber, as the blowdown of drawing water, clear husky, anticorrosion etc., waste lot of manpower and material resources, also influence urban environmental hygiene.
The purpose of this utility model is: provide a kind of waterproof antifouling manhole cover support, this well lid can effectively stop liquid, dirt etc. to invade the well chamber, has easy to use, advantages such as cost is with low cost, waterproof good antifouling effect.
The purpose of this utility model is achieved by the following technical solution: the manhole cover support that a kind of waterproof is antifouling, comprise closing disk, and it is characterized in that, also comprise the round frame and the rubber seal that are positioned at the closing disk bottom; The periphery of described round frame is provided with annular protrusion upwards; The downside of described closing disk is provided with and the corresponding downward annular protrusion of described annular protrusion; The internal diameter of the annular protrusion of the round frame of external diameter of the annular protrusion of described cover plate is smaller; Described rubber seal is located between two annular protrusions.
The antifouling manhole cover support of aforesaid waterproof of the present utility model, independently be installed on the following borehole wall of general load bearing well cover, form a sealing barrier, when having pollutant to infiltrate on the load bearing well cover, outside all being stoped by this manhole cover support, thereby it is indoor to make liquid, dirt etc. not enter well.Easy to use, advantages such as cost is with low cost, waterproof good antifouling effect that this manhole cover support has.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of an exemplary embodiments of the present utility model;
Fig. 2 is the A-A sectional view of an exemplary embodiments of the present utility model.
The antifouling manhole cover support of the utility model waterproof as illustrated in figs. 1 and 2 comprises closing disk 1, also comprises the round frame 2 and the rubber seal 3 that are positioned at closing disk 1 bottom; The periphery of circle frame 2 is provided with annular protrusion 4 upwards; The downside of closing disk 1 is provided with and annular protrusion 4 corresponding downward annular protrusions 5; The external diameter of annular protrusion 5 is smaller than the internal diameter of annular protrusion 4; Rubber seal 3 is located between annular protrusion 4 and the annular protrusion 5.
In the present embodiment, be provided with semicircle arc groove 6 in the outside of annular protrusion 5; Rubber seal 3 embeds in the deep-slotted chip breaker 6.
Closing disk 1 in the utility model well lid and circle frame 2 can be mixed and made into by in the materials such as engineering plastics, alloy one or more; Wherein can preferentially select polyvinyl chloride or modified polyvinyl chloride alkene plastics according to performance.Rubber seal 3 can be made by one or more modifications in the industrial rubber.
The utility model well lid in use at first will be justified frame 2 bonding being installed under the well head load bearing well cover with the sealing adhesive, simultaneously the arc sealing ring be embedded in the deep-slotted chip breaker 6, and closing disk 1 is pressed in the round frame 2.Can reach the purpose of sealed well lid like this by the elastic deformation of sealing ring 3, prevent that effectively the silt dirt from infiltrating the well chamber.Above-mentioned sealant can adopt one or more the compound uses in the technical grade bonding adhesive of market sale, can preferentially select the paste adhesive of indefinite form according to performance, as polyurethane sealing, modified silicone seal gum, acrylic sealant, polysulfide sealant.
