Open so that well lid departs from or misplaced from well head, easily occur people or thing falls to the risk of sewer pipe network.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of easy for installation, will not be by the hydraulic pressure in pipe network by well
Cover the two-way permeable prevention waterlogging fall arrest well lid washed open.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of two-way permeable prevention waterlogging fall arrest well lid,
Fixed seat and parallel spacing including being fixed at well head are located at the fixed network board of the fixed seat lower end；The horizontal stroke of the fixed seat
Section is annular, the axially moveable movable screen being provided with for filter sewage or rainwater in the middle part of the fixed seat；It is described
Movable screen is network structure, and its lower end is provided with vertical motion bar；The motion bar penetrates the fixed network board, and with it is described
The axially moveable connection of fixed network board, and the end of the motion bar is provided with limited block；The limited block has two, one of them
Located at the fixed network board lower end, another is big located at the spacing between the fixed network board upper end, and two pieces of limited blocks
In the thickness of the fixed seat；The edge of the fixed network board and the edge of the fixed seat are fixed by vertical connecting rod
Connection.
Further, the motion bar has two or three, and uniform right centered on the vertical axis of the movable screen
Claim arrangement.
By the way that motion bar is set into two or three so that what movable screen can be more stable moves up or fall, Bu Huifa
Raw rotation.
Further, the movable screen is cylinder, and is coaxially disposed with the fixed seat, the diameter of the movable screen
More than 30cm.
Designed by the movable screen of large area so that the circulation increase of water.
Further, the thickness of the fixed seat is less than 5cm；The thickness of the movable screen is less than or equal to the fixed seat
Thickness.
Further, the fixed network board, which is provided with, is used for the through hole that the motion bar is penetrated；The limited block is arranged fixation
In the outer wall of the motion bar, the limited block is cannula-like, has a diameter larger than the diameter of the through hole.
Pass through the fixation position-limiting action of limited block so that movable screen without departing from.
The beneficial effects of the utility model：By the way that traditional Sewage well cover is designed as into double-layer structure, and the activity on upper strata
Web plate a certain degree of can be moved up, but not depart from fixed seat all the time so that when hydraulic pressure is larger in pipe network, hydraulic pressure by movable screen to
It is upper to rush so as to occur gap between movable screen and fixed seat, current can be gone out out of gap faster, but movable screen
Tightly simply move up without misplacing or departing from, depart from or misplace from well head from without conventional well lid, will not go out
Existing people or thing fall to the risk of sewer pipe network.When normal hydraulic pressure, due to the Action of Gravity Field of movable screen itself and spacing
The position-limiting action of block, movable screen upper surface can keep same plane with fixed seat upper surface, from without influenceing road surface walking
People or the vehicle of traveling.

Fig. 2 is Fig. 1 front view schematic cross-sectional view.
Fig. 3 be Fig. 2 in movable screen move up after schematic diagram.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, fixed seat, 2, fixed network board, 3, movable screen, 4, motion bar, 5, limited block, 6, connecting rod.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
Two-way permeable prevention waterlogging fall arrest well lid as shown in Figure 1, Figure 2, Figure 3 shows, including the fixed seat that is fixed at well head and
Parallel spacing is located at the fixed network board of fixed seat lower end；The cross section of fixed seat is annular, and the middle part of fixed seat is lived vertically
The dynamic movable screen being provided with for filter sewage or rainwater；Movable screen is network structure, and its lower end is provided with vertical motion bar；
Motion bar penetrates fixed network board, and with the axially moveable connection of fixed network board, and the end of motion bar is provided with limited block；Limited block
There are two, one of them is located at fixed network board lower end, another is located at the spacing between fixed network board upper end, and two pieces of limited blocks
More than the thickness of fixed seat；The edge of fixed network board is fixedly connected with the edge of fixed seat by vertical connecting rod.
Motion bar has two or three, and is symmetrically arranged centered on the vertical axis of movable screen.By that will live
Lever is set to two or three so that what movable screen can be more stable moves up or fall, and will not rotate.Certainly, each
Two limited blocks are correspondingly provided with motion bar.
Movable screen is cylinder, and is coaxially disposed with fixed seat, and the diameter of movable screen is more than 30cm.Pass through large area
Movable screen design so that water circulation increase.
The thickness of fixed seat is less than 5cm；The thickness of movable screen is less than or equal to the thickness of fixed seat.
Fixed network board, which is provided with, is used for the through hole that motion bar is penetrated；Limited block is arranged the outer wall for being fixed on motion bar, spacing
Block is cannula-like, has a diameter larger than the diameter of through hole.Pass through the fixation position-limiting action of limited block so that movable screen will not take off
From.
During installation, it is only necessary to which fixed seat is fixedly mounted at well head, under movable screen is under self gravitation effect
Move, and without departing from well lid in the presence of limited block, so that movable screen is active all the time, when in sewer pipe net
Hydraulic pressure it is larger when, movable screen is by upward punching press, and in the presence of limited block and motion bar, movable screen is without departing from well
Lid, after the hydraulic pressure in pipe network recovers normal, movable screen is displaced downwardly to initial position automatically.Due to being additionally provided with below movable screen
