Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

Example 1

The utility model provides an inlaying water prevention safety device under well lid, the device includes the wall of a well 1, walling crib 2, cutting ferrule 3, connecting rod 4, connecting rod 5, bracing piece 6, backup pad 7, location arch 8. Well circle 2 is fixed in 1 inboardly of the wall of a well through expansion bolts, and apart from the installation of well head 100mm department, 2 a week of well circle is equipped with eight connection archs, and the system has the mounting hole on it, and the protruding nail of selling of being connected of eight bracing pieces 6 one end and 2 a week of well circle is articulated continuous, and the middle part of every bracing piece 6 is articulated continuous with connecting rod 4, the connecting rod 4 other end is articulated continuous with connecting rod 5, the outside cover of connecting rod 4 has cutting ferrule 3, and cutting ferrule 3 can slide on connecting rod 4, the connecting rod 4 outside has location arch 8 with the lower part system of connecting rod 5 hinged end, the cutting ferrule covers connecting rod 4 and connecting rod 5 junction simultaneously when being location arch 8, when connecting rod 4 and connecting rod 5 expand and be a straight line, cutting ferrule 3 gliding, just lock connecting rod 4 and connecting rod 5's junction. The other end of each connecting rod 5 is hinged with the well wall through a hinge support, the supporting rod 6 is welded at the bottom of the center of the supporting plate 7, the supporting plate 7 is a fan-shaped plate which divides the area of a round well mouth into eight equal parts, the supporting plate 7 is a mesh grid plate, water filtering holes are formed in the supporting plate 7, and the supporting plate 7 forms a well mouth shape after being unfolded.

When ponding was gone through this device, 8 supports were in the position of opening, and the cutting ferrule can slide down to the connecting rod end, and connecting rod and follower (connecting rod) collineation this moment, four-bar linkage are in the dead point position, guarantee that the connecting rod can not bounce back, are in safe position, and 8 grids merge into circularly in the backup pad, lock and the position of parallel well head, and the support grid board is netted, guarantees the circulation of well water. When the pedestrian walks to the well that the rainwater does not have the well lid like this, can be caught by safety device, avoid the emergence of accident. When accumulated water does not overflow the device in sunny days or rainy days, the device can be in the same working state as the device, only when the underground operation is needed, the cutting sleeve is lifted upwards by a distance by the iron hook, the support is folded, 8 grids in the support plate are divided into 8 sections to be attached to the well wall, and the working state of the device is recovered after the underground operation is finished.
