Technical field

The utility model relates to the device that a kind of municipal engineering are used, and more particularly, relates to the device that one way of life sewage, storm-water drainage are used.

Background technology

In urban construction, in urban road and city residential construction, in the residential quarter in cities and towns, often there is a sanitary sewage well at the place, access in each building, on well lid, have leaking hole, leaking hole can be arranged rainwater, also can open well lid for the workman of repairing catch pit and provide convenience, on the road of block, can see rainwater drainage well, enter rainwater, enter ice dissolution addle afterwards, on the catch basin cover that this draining is used, also there is leaking hole, also for repairing the workman of catch-basin, open well lid and provide convenience, in urban construction, also has aqueous vapor pipeline, supply line, the trench well of communication line, each is aboveground well lid, on each well lid, there is leaking hole, yet, poplar, the titbit of willow, the sandy soil in roadside, the flowers and plants fallen leaves in roadside, foreign material fall into small opening, with the passage of time, these falling-well matters may block catch pit, Urban Buried Pipeline Network desilting workload is very big, have the storm-water drainage of blocking one or several location, cause ponding row not fall, affect traffic, affect the appearance of the city.

City pipeline and circuit can have gutter, Urban Buried Pipeline Network, can there is no catch pit, sanitary sewage well and catch-basin, can have well lid, can there is no the leaking hole on well lid, the quantity of catch pit is big, and it is big that well lid leaking hole stops up result harm, affects big, should cause people's attention, the problem of eliminating leaking hole drawback should solve.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of well lid device of catch pit is provided.

When not raining, well lid leaking hole is closed automatically, and Sometimes When It Rains, well lid leaking hole is opened automatically, to ground ditch water discharge.

Mechanical type automatic device on well lid for a kind of catch pit, comprise well seat, it is characterized in that, the below of the leaking hole on well lid is provided with plug, the saucer shape that is shaped as back-off of plug, plug external surface is provided with the ditch that leaks under more than one, the top of plug is provided with the little stifled of pagoda shape, little stifled being inserted in the leaking hole on well lid, little stifled external surface is provided with the ditch that leaks on more than one, the little position that leaks ditch on stifled contacts with the leaking hole on well lid, little stifled external surface be provided with on leak that ditch is provided with plug external surface under the ditch that leaks communicate, the bottom of well lid is provided with support, and in the hole in the middle of support, position is connected with bolt and nut, and bolt is connected with lever, and one end of lever is fixed with plug, and the other end of lever is fixed with mass, and lever is connected with the mass of the other end.

The material of described well seat, well lid, support is metal, and the material of plug, lever, mass, bolt and nut is duroplasts.

The utility model has the advantage of, when not raining, under the effect of mass, block leaking hole, the upper surface contact small opening soffit of circular arc plug, prevents that poplar, willow titbit from entering lower well, prevent that foreign material from falling catch pit, prevent from stopping up drainage system; Once Sometimes When It Rains, under the gravity pressure of rainwater, promote plug downward, depart from the leaking hole at well lid place, can automatically carry out draining.Drain after rainwater, under the effect of mass, plug is upwards mentioned, and the leaking hole of automatic impaction well lid prevents that catch pit from blocking, and prevents that Urban Buried Pipeline Network from blocking, and favourable traffic, prevents contaminated environment.This mechanical type automatic device, simple in structure, to make easily, selling price is low, and easily, operating efficiency is high, welcomed by the people in maintenance.

accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Fig. 2 is A partial view in Fig. 1.

In figure, have well seat 1, well lid 2, leaking hole 3, suspension bracket 4, bolt 5, plug 6, lever 7, mass 8, little stifled 9, on leak ditch 10, under the ditch 11 that leaks.

the specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is made further and being described in detail.

As shown in the figure, mechanical type automatic device on well lid for this catch pit, comprise well seat 1, it is characterized in that, leaking hole 3 belows of well lid 2 are provided with plug 6, the saucer shape that is shaped as back-off of plug 6, plug 6 external surfaces are provided with the ditch 11 that leaks under more than one, the top of plug 6 is provided with the little by stifled 9 of pagoda shape, in little stifled 9 leaking holes 3 that are inserted on well lid 2, little stifled 9 external surface is provided with the more than one ditch 10 that leaks on lower, leak on little stifled 9 the contacting of ditch 10 positions and leaking hole 3 on well lid 2, little stifled 9 external surface be provided with on leak that ditch 10 is provided with plug 6 external surfaces under the ditch 11 that leaks communicate, the bottom of well lid 2 is provided with support 4, and in the hole in the middle of support 4, position is connected with bolt 5 and nut, and bolt 5 is connected with lever 7, and one end of lever 7 is fixed with plug 6, and lever 7 other ends are fixed with mass 8, and lever 7 is connected with the mass 8 of the other end.

Described a kind of for catch pit the material of well lid (1), well lid 2, support 4 be metal, the material of plug 6, lever 7, mass 8, bolt 5 and nut is duroplasts.

Bolt 5 has rotating shaft effect, mass 8 can be a metal sheet or bonding jumper, if be subject to the restriction of position dimension size, also can make the size of mass 8 widen, plug 6, mass 8 match with weight, to adapt between plug 6 and leaking hole 3, closely close, this mechanical type automatic device, again for automatically opening, close the object of the leaking hole 3 of well lid 2.
