DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] Example 1: Please refer to Figure 1-5 The inspection well drainage pipeline cleaning device provided by the utility model includes a collecting tube 100 and an inspection well main body 101. A hoisting assembly 109 is arranged inside the collecting tube 100. The hoisting assembly 109 includes a movable rod 114. A pull ring 115 is fixedly installed on the upper end of the movable rod 114. A T-shaped block 110 is installed on the bottom end of the movable rod 114. Two symmetrical springs 111 are fixedly installed inside the T-shaped block 110. The ends of the two springs 111 away from each other are fixedly installed with locking blocks 112. Push rods 113 are fixedly installed on the upper end surfaces of the two locking blocks 112. The push rods 113 both slide through the T-shaped block 110. The ends of the two locking blocks 112 away from each other slide through the T-shaped block 110. The upper end surface of the collecting tube 100 and the penetrating end of the locking block 112 are both set to corresponding wedge shapes, and the inner wall of the collecting tube 100 is provided with a limiting groove corresponding to the locking block 112.
[0023] Working principle: When it is necessary to lift the sludge deposited in the inspection well body 101, the lifting assembly 109 is inserted into the collection tube 100. When the locking block 112 contacts the wedge surface corresponding to the collection tube 100, the locking block 112 will move toward the inside of the T-shaped block 110 under the action of the downward pressure, and drive the spring 111 to compress. At this time, the locking block 112 will move along the inner wall of the collection tube 100. When the locking block 112 reaches the collection tube 100, the locking block 112 will move toward the inside of the T-shaped block 110. When the inner wall of the collecting cylinder 100 corresponds to the limiting groove, the restoring force of the spring 111 will be applied to the locking block 112, pushing the locking block 112 and pushing it into the limiting groove. At this time, the staff can hang the collecting cylinder 100 by tying a rope to the pull ring 115. When it is necessary to release the connection of the lifting component 109 on the inner side of the collecting cylinder 100, pull the two push rods 113 to make the locking block 112 leave the limiting groove inside the collecting cylinder 100 to release the connection.

A U-shaped pull rod 124 is installed. When in use, the sealing between the T-block 110 and the locking block 112 is strengthened by the sealing pad 125 to prevent water stains from entering the T-block 110 and adhering to the surface of the spring 111. The combined length between the movable rod 114 and the T-block 110 is changed through the threaded connection between the movable rod 114 and the T-block 110. The movement of the T-block 110 in the movable rod 114 is limited by the limit block 122. When the collecting cylinder 100 is hoisted, the movement of the collecting cylinder 100 is guided by the guide block 120.
