Abstract
The invention discloses a manhole cover preventing silt from falling into the well mouth. The manhole cover is provided with a cover opening hole, a silt-preventing cover capable of moving in the vertical direction is arranged at the cover opening hole, springs are connected between the silt-preventing cover and a manhole cover body, and the silt-preventing cover shields the cover opening hole from bottom to top under action of the springs. The manhole cover can prevent that the silt falls into the well mouth through the cover opening hole in the manhole cover body, opening of the manhole cover body is not hindered, and in the opening process, people still can insert a claw hook from the cover opening hole to lift the manhole cover just like opening a common manhole cover.
Description
Technical field
The present invention relates to the manhole cover used at the well head place of all kinds of underground pipeline.
Background technology
The manhole cover used at the well head place of all kinds of underground pipelines such as sewer, underground cables pipeline, is all provided with hole of uncapping.When opening manhole cover, inserting grapple from hole of uncapping can mention manhole cover.In routine use, ground silt easily falls into well head from the hole of uncapping of manhole cover, causes various problem.
Summary of the invention
The object of this invention is to provide a kind of manhole cover preventing silt from falling into well head.
The present invention is achieved in that the manhole cover preventing silt from falling into well head, manhole cover is provided with hole of uncapping, and is provided with sand prevention lid movable up and down, between sand prevention lid and manhole cover, is connected with spring at the hole place that uncaps, under spring force, sand prevention lid is sheltered cap bore from lower to upper.
As preferred forms, under the state that described sand prevention lid is sheltered cap bore, the top of described sand prevention lid is concordant with the top in described hole of uncapping.
Advantage of the present invention is, silt can be stoped to fall into well head by the hole of uncapping of manhole cover, does not hinder again the operation of uncapping of manhole cover, when opening manhole cover, still can insert grapple from hole of uncapping common manhole cover and is mentioned by manhole cover as opened.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the schematic diagram after the sand prevention cover in Fig. 1 is backed down.
Detailed description of the invention
Simultaneously see Fig. 1 and Fig. 2, manhole cover 1 is provided with hole 2 of uncapping, and is provided with sand prevention lid 3 movable up and down at the hole place that uncaps, and sand prevention lid 3, using the screw 4 erect as guide peg, can slide up and down.Screw 4 is fixed on the bottom surface of manhole cover 1.Between sand prevention lid 3 and manhole cover 1, be connected with Compress Spring 5, spring 5 is enclosed within screw 4, and the lower end of spring 5 acts on the stub end of screw 4, and the top, upper end of spring 5 press against sand prevention lid 3.Under spring force, sand prevention lid 3 is sheltered cap bore 2 from lower to upper, plays and prevents silt hole 2 of passing through to uncap from falling into the effect of well head.
As preferred forms, as shown in Figure 1, under the state that sand prevention lid 3 is sheltered cap bore 2, the top of sand prevention lid 3 is concordant with the top in hole 2 of uncapping.Cap bore can be sheltered to greatest extent like this, the top because of hole of uncapping can be avoided again uneven and cause current obstacle to pedestrian.
When opening manhole cover, from uncapping, grapple is inserted in hole 2, is backed down downwards as shown in Figure 2 by sand prevention lid 3, just can be opened by whole manhole cover 1 as opened common manhole cover.
