Description

Technical Field

[0001] The utility model belongs to the technical field of winding devices, and in particular relates to an electric winding device for an array induction coil. Background Art

[0002] The high-resolution array induction logging instrument is based on the principle of electromagnetic induction. The basic unit of the array induction coil system inside it adopts a three-coil system structure (one transmitting unit and two receiving units). The transmitting circuit generates a 10.4kHz square wave and provides it to the transmitting coil, so that it establishes a changing electromagnetic field in the formation medium around the wellbore and induces the formation to generate an induced current, generating a secondary field. The secondary field generates an induced electromotive force in the receiving coil array, that is, the measured signal. This signal directly reflects the level of formation conductivity. Finally, it is compressed and encoded by the main control circuit and sent to the ground logging system via the logging cable. It can be seen from this that the coil manufacturing process of the instrument has a crucial impact on the performance of the instrument and is the core component of array induction.

[0003] At present, the coil substrate is made of ceramic material, and there are grooves ranging from 18 to 180 turns on the substrate. During the production process, the copper wire needs to be evenly wound around the substrate. Under the high temperature and high pressure environment underground, the coil system cannot be loose or broken.

[0004] At present, the copper wire is usually wound manually, that is, the worker rotates the coil base with one hand and controls the copper wire to be wound on the coil base with the other hand. However, with the manual winding operation method, it is difficult for the worker to control the uniform rotation of the coil base, which will affect the winding effect of the copper wire and thus affect the reliability of the product. In addition, the manual winding operation method has low production efficiency, increases the labor intensity of the workers, and is prone to hand injuries, which needs to be improved.

It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other arbitrarily without conflict.

[0035] like Figure 1 , Figure 2 The utility model is shown in an embodiment of the utility model, in which an array induction coil electric winding device is disclosed, including a support frame 1, a support seat 2 is fixedly connected to the support frame 1, a rotating shaft 3 is horizontally arranged on the support seat 2, and the rotating shaft 3 and the support seat 2 form a rotational fit through a bearing.

At the same time, a control mechanism 9 is provided on the receiving seat 6, and the control mechanism 9 is used to drive the tightening plate 7 to move toward the limiting portion 4 and make the tightening portion 8 press against the end of the coil base, so that the limiting portion 4 and the tightening portion 8 respectively fix the corresponding ends of the coil base.

[0037] The coil base is placed between the limiting part 4 and the tightening part 8, one end of the coil base is fixed by the limiting part 4, and then the tightening plate 7 is driven by the control mechanism 9 to drive the tightening part 8 to move toward the limiting part 4 until the tightening part 8 is pressed against the other end of the coil base. Then, the motor driving mechanism 5 can be started to make the coil base rotate at a constant speed, and at this time, the staff can wind the copper wire on the coil base.

[0038] The array induction coil in this embodiment is an electric winding device, which uses a motor drive mechanism 5 to control the uniform rotation of the coil base to achieve semi-automatic winding of the copper wire, greatly improving production efficiency and effectively reducing the labor intensity of the staff. Compared with the manual winding method, this design allows the staff to better control the winding of the copper wire without controlling the rotation of the coil base, making the winding of the copper wire more uniform and dense, ensuring the winding effect of the copper wire, and improving the reliability of the coil system.

At the same time, a 359-2-103L10K precision multi-turn potentiometer can also be set as a top-level control system to adjust the speed and forward and reverse rotation of the servo motor, and accurately control the motor speed and forward and reverse rotation.

[0045] In one embodiment, Figure 1 , Figure 2 As shown, a support shaft 10 is horizontally arranged on the support frame 1, and the support shaft 10 is located directly below the support seat 2 and the receiving seat 6. The support shaft 10 is detachably connected to the support frame 1, and the support shaft 10 can pass through the base tube of the copper wire bundle to achieve the suspension of the copper wire bundle.
