[0027] As Figures 1 to 4 shown, the present application provides a collar-type sensor with improved lead wires, including: a sensor body 1, on one side of which there is a wire passing hole and a signal wire is led out; a manipulator mechanism, including a support rod 2 and a front fork structure 3 provided at the front end of the support rod, and the front fork structure 3 is hinged to the side walls on both sides of the sensor body 1; a wire passing hole connecting elbow 4, the elbow 4 is connected to a bent pipe 5, the bent pipe 5 is connected to a straight pipe 6, and the straight pipe 6 is connected to a metal hose 7; the elbow 4, the bent pipe 5, and the straight pipe 6 are used to bypass the front fork structure 3, and the metal hose 7 is connected to the support rod 2 through a plurality of clamps 8 and is arranged to extend in the same direction as the support rod 2; the signal wire sequentially passes through the elbow 4, the bent pipe 5, the straight pipe 6, and the metal hose 7 and is connected to a plug 9.

[0028] Specifically, there is a wire passing hole on one side of the sensor body 1 for leading out the signal wire. The manipulator mechanism includes a support rod 2 and a front fork structure 3, and the front fork structure 3 is hinged to the side walls on both sides of the sensor body 1, allowing the sensor body 1 to rotate within a certain range. The signal wire is led out through the elbow 4, the bent pipe 5, and the straight pipe 6 for bypassing the front fork structure 3. The metal hose is connected to the support rod 2 through the clamp 8 and is arranged to extend in the same direction as the support rod 2 to protect the signal wire from mechanical stress.

[0029] Through the design of the elbow 4, the bent pipe 5, the straight pipe 6, and the metal hose 7, the full coverage of the signal wire is realized, effectively protecting the signal wire, thereby improving the reliability of the sensor signal transmission. Secondly, the metal hose 7 is connected to the support rod 2 through a clamp and is arranged to extend in the same direction as the support rod 2, making the lead-out of the signal wire more neat and orderly.

[0030] In some embodiments, an outer protective sleeve 10 is sleeved on the outer side of the metal hose 7 between the straight pipe 6 and the first clamp 8, and the end of the outer protective sleeve 10 is fixed to the metal hose 7 through a fixing hoop 11. When the sensor body 1 is adjusted in angle, the metal hose 7 between the straight pipe 6 and the first clamp 8 rotates with a large amplitude and is prone to fatigue and damage. The design of the outer protective sleeve 10 further protects the signal wire at this place, and the end of the outer protective sleeve 10 is also fixed to the metal hose 7 through the fixing hoop 11 to ensure the stability of its position and the reliability of the protection.

[0031] In some embodiments, an anti-bending spring 12 is sleeved outside the outer protective sleeve 10. The anti-bending spring 12 is used to prevent the outer protective sleeve 10 and the metal hose 7 from being excessively bent or folded during movement, thereby maintaining the integrity of its internal structure and the stability of the signal line.

[0032] In some embodiments, the signal line is welded to the metal inner wire. The signal line is connected to the plug 9 through the metal inner wire. A reducing sleeve 13 is sleeved at the connection between the signal line and the metal inner wire. The small end of the reducing sleeve 13 is fastened to the outer sheath of the signal line, and the reducing sleeve 13 is filled with high-temperature resistant solid glue to prevent the solder joint between the signal line and the metal inner wire from being pulled off. The metal inner wire serves as an intermediary, enhancing the connection strength between the signal line and the plug and improving the signal transmission stability. The design of the reducing sleeve protects the solder joint between the signal line and the metal inner wire, preventing damage to the solder joint under the action of external force or high temperature, and improving the reliability and service life of the sensor. The filling of the high-temperature resistant solid glue enhances the protection effect of the encapsulation tube, enabling the sensor to maintain stable performance in harsh environments.

[0033] In some embodiments, the manipulator mechanism further includes a fulcrum support frame 14, a handle 15, and an oil cylinder 16. The fulcrum support frame 14 is disposed at a predetermined fulcrum of the support rod 2 and is hinged to the support rod 2. The handle 15 is connected to the rear end of the fulcrum support frame 14. One end of the oil cylinder 16 is fixed to the fulcrum support frame 14, and the other end is connected to the support rod 2. The fulcrum support frame 14 provides a stable support point for the support rod 2, facilitating the control of the rotation of the support rod 2, thereby controlling the position of the sensor body 1. The design of the handle 15 enables the operator to more conveniently control and operate the manipulator mechanism, improving its usability. The oil cylinder 16 provides an automatic control power source for the manipulator mechanism, enabling the support rod 2 to perform automatic and precise movement adjustment.

[0034] In some embodiments, the sensor body 1 includes an inner ring sleeve, a detection coil, and an outer ring sleeve. The inner ring sleeve is sleeved outside the long nozzle 17 and is connected to the front fork structure 3. A circle of inner grooves is provided on the outer peripheral wall of the inner ring sleeve. The detection coil is wound and fixed in the inner grooves. The outer ring sleeve covers the inner grooves. The detection coil is connected to the signal line, and the outer ring sleeve is provided with a wire passing hole for leading out the signal line. The inner ring sleeve is sleeved outside the long nozzle 17 and is connected to the front fork structure 3, enabling the sensor body 1 to be stably installed on the long nozzle 17 and move along with the front fork structure 3. The inner grooves are used for winding and fixing the detection coil, and the detection coil detects the slag in the molten steel flow through the principle of electromagnetic induction. The outer ring sleeve then covers the inner grooves, playing a role in protecting and fixing the detection coil. The detection coil is connected to the outside through the signal line for transmitting the detected data. The outer ring sleeve is also provided with a wire passing hole for leading out the signal line.

[0035] In some embodiments, the front fork structure 3 includes two side plates connected to the support rod 2, and the two side plates are respectively rotatably connected to the outer walls on both sides of the sensor body 1 through pin shafts. The design of the front fork structure 3 enables the sensor body 1 to rotate relative to the front fork structure 3 within a certain range, so that the detection angle or position can be adjusted, enhancing adaptability. Since the front fork structure 3 is connected to the support rod 2, the rotation of the sensor body 1 will also drive the corresponding movement of the support rod 2, realizing the collaborative work of the sensor and the manipulator mechanism.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
