Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example one

As shown in fig. 1, fig. 2 and fig. 3, the present embodiment provides a wire-controllable spring type hole packer, including: the device comprises a connector 1, an outer ring 2, a sealing layer 3, a spring strut 4, a spring 5, a limiting rod 6, a short plugging control line 7, a concentrator 8, a long control line 9, an extraction pipe 10, a grouting pipe 11 and an extraction drill hole 12.

The connector 1 is sleeved outside the tail end of the extraction pipe 10 and connected with the extraction pipe 10;

the sealing layer 3 is fixed outside the connector 1, the outer ring 2 is connected to the outer side of the sealing layer 3, the spring struts 4 are fixed on the side faces of the outer ring 2, the springs 5 are connected between the spring struts 4, the limiting rods 6 are sleeved on the spring struts 4, the plugging control line short wires 7 are connected outside the limiting rods 6 and are combined and connected to the concentrator 8, the concentrator 8 is simultaneously connected with the control line long wires 9, and the control line long wires 9 extend out of the extraction drill hole 12; one end of the sliding chute 13 is fixed below the spring support 4, and the other end of the sliding chute is suspended, so that four sliding chutes are provided for the movement of the spring 5.
