Description
Technical Field
The invention relates to the field of protective devices, in particular to an adjustable polished rod anti-breaking device.
Background
The polish rod is not easy to break when the normal oil well is within 1000 m in depth. When the depth of the oil well exceeds 1000 m to 2000 m, the load of the pumping unit is increased due to the ever increasing depth of the oil well, and the tension and gravity acting on the polish rod are increased compared with the load of the oil well with the depth of 1000 m. Along with the increase of the production time, the polished rod can be broken when reaching a certain fatigue strength. The polish rod directly drops in the oil pipe after being broken, and the polish rod sealer can not form a closed space due to the loss of the polish rod, so that a large amount of high-pressure liquid in the well can leak outwards from a gland at the top of the polish rod sealer, and the oil is leaked in a large area, so that serious environmental pollution is caused. If the polished rod fracture phenomenon cannot be found in time, emergency treatment cannot be carried out in time, and direct environmental pollution and indirect economic loss caused by the emergency treatment cannot be measured. With the continuous expansion of the field of crude oil exploitation, the field has been expanded from land to the edge of shallow sea, and the offshore artificial island is developed towards the direction of deep sea, so that the damage generated is immeasurable.
Therefore, a corresponding solution must be developed for the hazard caused by the polished rod fracture.

Detailed Description
The adjustable polish rod break preventing device of the present invention will be further described in detail with reference to the accompanying drawings.
With reference to fig. 1-3, an adjustable polish rod anti-breaking device comprises a polished rod eye 1, a polish rod 2, a bearing device 3 and a square clamp 4 arranged on the polish rod 2;
a polish rod sealer 5 is arranged at one end of the polish rod 2;
connecting bolts 6 are symmetrically arranged at two ends of the bearing device 3 along the length direction, the other end of each connecting bolt 6 is connected with the rope hanger 1, and the distance between the bearing device 3 and the rope hanger 1 can be changed by adjusting the distance of the connecting bolts;
a U-shaped groove 7 is formed in the middle of one side of the bearing device 3, the polished rod 2 is placed in the U-shaped groove 7, a fixing plate 8 is arranged on the U-shaped groove 7, and two ends of the fixing plate 8 are connected with the bearing device 3 through bolts to fix the polished rod 2 in the U-shaped groove 7;
