Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in figures 1 to 3, the utility model comprises a shaft 1, the upper end of the shaft 1 comprises a well cover 2 and a well cover support, the lower part of the shaft 1 is provided with a water inlet and outlet pipe 3, a horn-shaped guide hopper 4 with a big top and a small bottom is arranged below the water inlet and outlet pipe 3, the lower end of the guide hopper 4 is provided with a sedimentation tank 5, a sedimentation tank 6 is arranged in the sedimentation tank 5, the upper end of the sedimentation tank 6 is fixed with a stay cord, the other end of the stay cord is fixed on the well cover 2, the wall of the shaft 1 is provided with a vertical groove 7, a plurality of support rods 8 are hinged in the vertical groove 7 along the length direction at intervals, the free end of each support rod 8 is fixed with a rectangular frame 9, the outer side of the plurality of rectangular frames 9 is provided with a vertical rod 10, the plurality of rectangular frames 9 are hinged on the vertical rod 10, the vertical rod 10 moves up and down to drive the plurality of support rods 8 to rotate synchronously around a hinge shaft, a coil spring 11 which can reset the support rod 8 at the uppermost end is fixed at a hinge position, a limiting block 12 is arranged below the lowest supporting rod 8.

In order to realize the installation of stay cord and deposit fixed on a section of thick bamboo 6, it has a plurality of rings to deposit the circumference equipartition on a section of thick bamboo 6, is fixed with a rope on every ring, and the other end and the stay cord of a plurality of ropes are fixed, and 2 bottoms of well lid are equipped with solid fixed ring, and the stay cord is close to the one end of well lid 2 and fixes on solid fixed ring.

In order to enable the sedimentation cylinder 6 to be pulled out of the wellhead, the diameter of the wellhead is larger than the outer diameter of the sedimentation cylinder 6.

In order to realize that the sedimentation cylinder 6 can discharge redundant water at the upper end of the sedimentation cylinder when being pulled, drain holes are densely distributed on the side wall of the upper end of the sedimentation cylinder 6.

In order to realize the hinging of the support rod 8 in the vertical groove 7, a bearing is arranged on the groove wall of the vertical groove 7, and a hinging shaft of the vertical rod 10 is fixed in the bearing.

The utility model discloses a concrete working process is: under the effect of spring 11 under the condition of no external force, make its free end keep the ascending state of slope under the effect of spring 11, this process makes under the effect of montant 10 read a branch 8 synchronous rotation, the ladder that 8 rectangular frames 9 of branch formed is in the position that is close to the section of thick bamboo wall this moment, if need directly open well lid 2 when clearing up the silt in the section of thick bamboo 6 of depositing, through hoisting equipment through the stay cord with depositing section of thick bamboo 6 upwards pulling and pull out from the well head and can realize the clearance of depositing section of thick bamboo 6, after the completion with depositing section of thick bamboo 6 place back in the sedimentation tank in the stay cord through the stay cord can, the direction is fought 4 can assist the reseing of depositing section of thick bamboo 6, the stability of depositing section of thick bamboo 6 when many ropes can assist the pulling stay cord, the position of ladder can not rather than interfering when the pulling deposits section of thick bamboo 6 and shifts up, the wash port can discharge surplus water and reduce the weight when pulling and rising depositing section of thick bamboo 6.

When the personnel that need go into the pit and inspect, open 2 workman on well lid and push down with the foot branch 8 of tilt up earlier, the spring 11 atress is tensile this moment, make the ladder to the direction of keeping away from the section of thick bamboo wall remove at the in-process that pushes down, until branch 8 and stopper 12 contact of bottommost end, 8 levels of branch this moment, make the workman be the ladder reliable and stable using under the effect of workman's own gravity and the limiting displacement of stopper 12 to the ladder is more handy when keeping away from the section of thick bamboo wall use this moment.

The significant benefits of the present device: this device designs out the telescopic ladder according to 1 inner space structure of pit shaft and replaces traditional fixed ladder for the ladder does not take place to interfere with a section of thick bamboo 6 that deposits when a section of thick bamboo 6 is deposited in the pulling, can realize the ladder facilitate use again when overhauing, makes whole inspection shaft convenient high efficiency more when using.
