The supporting capacity of the erecting mode is higher, so that the cable drum is more stable during paying off, and the cable drum can be matched with cable drums of different specifications.

The utility model relates to the technical field of cable logging, and discloses a multifunctional antimagnetic wellhead device which comprises a wellhead baffle, an outer circle magnetic conduction pipe barrel and an inner circle magnetic conduction pipe barrel, and further comprises fixed transverse plates, a fixed transverse plate, a fixed transverse plate, a fixed transverse plate, a fixed transverse plate and a fixed transverse plate, wherein the fixed transverse plates are fixedly installed on the inner wall of the outer circle magnetic conduction pipe barrel circumferentially at equal intervals; by rotating the positioning disc, the bottom conical fluted disc can drive multiple sets of bevel gears, the corresponding ball screws can synchronously rotate on the inner side wall of the annular plate, and the movable transverse plate can slide in the fixed transverse plate, penetrate through a through groove in the joint and extend to the outer side of the outer circle magnetic conduction pipe barrel. When the movable transverse plates extend to the well mouth from the outer side of the horn-shaped outer circle magnetic conduction pipe barrel to connect the anti-magnetic well mouth, the connection stability of the outer circle magnetic conduction pipe barrel and the center position of the well mouth can be achieved through the multiple sets of movable transverse plates which are arranged in the circumferential direction; therefore, the logging cable is more stable during paying off.

The invention discloses a cable reel conveying device, and belongs to the technical field of power construction, the cable reel conveying device comprises a frame, a pay-off mechanism is arranged on the frame, the pay-off mechanism comprises a transversely arranged supporting beam, the supporting beam is connected with the frame through a rotating shaft, the rotating angle of the supporting beam is 360 degrees, the middle part of the supporting beam is vertically connected with a stand column, and the stand column is connected with the pay-off mechanism. The stand column is provided with a lifting shaft matched with a cable reel shaft hole. The two sides of the stand column are provided with supporting arms used for supporting the bottom of the supporting disc. An operator only needs to move the device, the lifting shaft is inserted into a shaft hole of a ground cable reel, and then the motor can be driven to stably lift the cable reel to a working position. In this way, additional hoisting equipment and heavy manual carrying are completely abandoned, autonomous loading and aerial precise positioning of the cable reel are achieved, and the operation safety and efficiency are greatly improved; and the combination of the baffle disc and the locking nut forms reliable axial locking, so that the cable reel is prevented from falling off from the shaft end in the lifting and transportation processes.

The utility model relates to the technical field of underground water level detection, in particular to a portable underground water level detector. The utility model provides a portable underground water level detector which is convenient to grasp and carry and is convenient to guide a tape, so that the paying-off is stable, and the paying-off does not need to be manually held by hands. A portable underground water level detector comprises a bottom frame, a mounting shell, a fixing shaft, a rotating roller and the like, the mounting shell is connected to the front portion of the bottom frame, the fixing shaft is connected to the middle of the mounting shell, and the rotating roller is rotationally connected to the fixing shaft. The sliding pull rod is moved downwards and then rotated rightwards to drive the rotating wheel to rotate on the mounting shell, so that the sliding pull rod faces the underground water level monitoring well, and the effects that the tape measure can be conveniently guided while the tape measure can be conveniently grabbed and carried, paying-off is stable, and paying-off does not need to be manually held by hand are achieved.
