In order to solve the problems, the technical scheme adopted by the motor-pumped well pipe is as follows: have the body of ring flange including both ends be provided with the connecting bolt hole on the ring flange and cross the wire casing cross the pipe side that the wire casing corresponds and be provided with the cable buckle, the cable buckle includes that the cross-section is the interlude of arcuation and the blank pressing that is located this interlude both sides, the interlude with body lateral surface forms the cable passageway the blank pressing outside interval is provided with fixed fin, with fixed fin corresponds the position and is provided with "U" type staple bolt.
The additional technical characteristics are as follows:
limiting bulges are arranged on the outer sides of the pipe bodies on the two sides of the blank holder;
a flange protection sheet is arranged at the end part of the middle section of the arc shape, and the length of the flange protection sheet is equal to the thickness of the flange plate;
the cable buckle is two sections which are arranged up and down.
Compared with the prior art, the motor-pumped well casing pipe provided by the utility model has the following advantages: one of which, because the pipe body with flanges at two ends is included, the flanges are provided with connecting bolt holes and wire passing grooves, the side surface of the pipe body corresponding to the wire passing grooves is provided with a cable buckle plate, the cable buckle plate comprises a middle section with an arc-shaped section and press edges positioned at two sides of the middle section, the middle section and the outer side surface of the pipe body form a cable channel, the outer side of the press edges are provided with fixed fin plates at intervals, the corresponding position of the fixed fin plates is provided with a U-shaped hoop, when the well pipe is lowered, the two ends of the cable are firstly clamped into the wire passing grooves on the flanges at two ends of the well pipe, the cable is pasted on the side surface of the pipe body, the cable buckle plate is buckled at the outer side of the cable, the cable buckle plate is fixed by the U-shaped hoop, then the well pipe is lowered, after the well pipe is lowered, the other well pipe is connected, then the cable is fixed until the pump is lowered to the set position, in the process of lowering the well pipe, the cable in the well is positioned in the cable channel and cannot rub against the well wall, the service life of the cable is long, the construction is simple, two ends of the cable pinch plate are propped against the side face of the flange plate, and the cable pinch plate and the pipe body cannot slide relatively in the axial direction; secondly, because the limiting bulges are arranged on the outer sides of the pipe bodies on the two sides of the blank holder, the two side edges of the cable buckle plate are clamped in the limiting bulges, the cable buckle plate is prevented from moving along the circumferential direction of the pipe bodies, the installation is more convenient, and the position is more accurate; thirdly, as the end part of the middle section of the arc shape is provided with the flange guard piece, the length of the flange guard piece is equal to the thickness of the flange plate, and the flange guard piece is positioned at the radial outer side of the wire passing groove, the abrasion of the cable at the wire passing groove is further avoided; fourthly, because the cable buckle is two sections of arranging from top to bottom, general well casing length is about 3 meters, and constructor only need be about 1.5 meters with the height that the cable lifted, and the construction is more convenient.
