Example Embodiment
[0026] Embodiment 1
[0027] Such as figure 1 , 2 As shown, an in-pipe intelligent occluder provided by the present invention includes:
[0028] A main driving cylinder 1, the main driving cylinder 1 has a cylinder body 11, a piston 12, and a piston rod 13 connected to the piston 12. The main driving cylinder 1 is preferably a hydraulic cylinder;
[0029] A pressure head 2 connected to the end 131 of the piston rod 13 away from the piston 12;
[0030] An actuator plate 3 connected to the cylinder 11;
[0031] An squeeze bowl 4, which is slidably arranged between the pressure head 2 and the actuator plate 3. The squeeze bowl 4 has an inclined sliding cone surface 41 and an extrusion end surface 42;
[0032] At least two locking sliders 5, preferably eight and evenly distributed in the circumferential direction, to ensure balanced locking force. The eight locking sliders 5 are respectively connected to eight auxiliary driving cylinders 15, and each auxiliary driving cylinder 15 is ...
Example Embodiment
[0047] Embodiment 2
[0048] As shown in Figure 5, the structure, principle and effect of this embodiment are basically the same as those of Embodiment 1, and will not be repeated. The difference is that the signal transceiving device 7 and the miniature main hydraulic system 14 are not installed in the pipe for intelligent blocking. In the hollow chamber 8 inside the device, it is connected to the outside of the smart occluder in the tube.
[0049] Specifically, a sealing cylinder 70 is attached to the outer end surface 23 of the pressure head 2, the signal transceiver 7 and the control module 140 of the miniature main hydraulic system 14, the battery pack 149, the oil tank 141 of the pressure holding circuit, the hydraulic pump 144 and All hydraulic components (not shown in the figure) are arranged in the sealed cylinder 70. Of course, the sealing cylinder 70 can also be hung on the outer end surface 33 of the actuator disk 3 without limitation. At this time, each support wheel ...

Abstract
The invention provides an intraductal intelligent plugging device, which comprises a main drive cylinder, a pressure head, an actuator disk, an extrusion bowl, at least two locking slide blocks, a ring spacer and a signal transceiver device, wherein, the main drive cylinder is provided with a cylinder body, a piston and a piston rod connected with the piston; the pressure head is connected with the end of the piston rod far away from piston; the actuator disk is connected with the cylinder body; the extrusion bowl is arranged between the pressure head and the actuator disk in a sliding way, and the extrusion bowl is provided with a tilted conical slide surface and an extrusion end face; each of the two locking slide blocks is connected with a subsidiary drive cylinder, and each subsidiary drive cylinder is fixed on the actuator disk; the bottom surface of the locking slide block is matched with the conical slide surface of the extrusion bowl in a sliding way, and the locking slide block performs the locking function in a radial expansion way when sliding upward along the conical slide surface; the ring spacer is arranged between the pressure head and the actuator disk, and is extruded by the extrusion end face of the extrusion bowl to perform the plugging function in a radial expansion way; the signal transceiver device is connected with the intraductal intelligent plugging device to receive control signals to drive the main drive cylinder.
Description
technical field [0001] The present invention relates to a plugging device among plugging tools for pipeline maintenance of water, oil, gas and other media, in particular to a remote-controlled intelligent plugging device in a high-pressure pipe that can self-block and unblock in high-pressure pipes. Background technique [0002] Pipeline transportation is the most economical and reasonable transportation method for oil and gas. By the end of 2006, the total length of my country's long-distance oil and gas pipelines had exceeded 50,000 kilometers, including about 30,000 kilometers of natural gas pipelines, about 15,000 kilometers of crude oil pipelines, and about 5,600 kilometers of refined oil pipelines. At present, a number of oil and gas regional pipeline networks have been formed in my country, including relatively complete regional natural gas pipeline networks in Sichuan-Chongqing, North China and the Yangtze River Delta regions, the main framework of regional natural g...
