During actual operation, spark detection requires applying high voltage to the equipment, causing the voltage to break through the air and generate sparks. Therefore, it needs to be protected to prevent harm to personnel. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PTFE tube rapid spark detection device, comprising a base plate, a protective shell, and a feed port, wherein the protective shell is fixedly connected to the top of the base plate, and the feed port is arranged on both sides of the two protective shells;

[0007] A detection structure is provided in the middle of the top of the bottom plate, and the detection structure is provided with a fixed ring, and the fixed ring is fixedly connected to the top of the bottom plate, one end of the fixed ring is hinged with a rotating ring, and the fixed ring and the rotating ring form an annular structure with each other, a plurality of electrodes symmetrically distributed in the center are fixedly connected to the inside of the fixed ring and the rotating ring, and a connecting block is rotatably connected to the inside of the electrode, an automatic reset shaft is provided at the connection between the connecting block and the electrode, and the connecting block points to the middle of the annular structure formed by the fixed ring and the rotating ring when in an initial state;

[0008] A metal cage distributed in a mesh structure is fixedly connected to the inner side of the protective shell, and the metal cage forms the inner side of the space with the bottom plate and the protective shell respectively.

[0009] Preferably, a sealing cover is fixedly connected to the outside of the rotating ring, a handle is fixedly connected to the outside of the sealing cover, and a magnet is fixedly connected to the end of the sealing cover. Wires are provided inside the fixed ring and the rotating ring, and one end of the wire extends to the outside of the fixed ring and the rotating ring and is fixedly connected to an external wire.

[0010] Preferably, a slot is provided in the middle of the protective shell, and the interior of the slot is engaged with the sealing cover, and the magnet is located at the joint between the sealing cover and the protective shell.

[0011] Preferably, six fixed support members are fixedly connected to the top of the base plate, and the six fixed support members are arranged in groups of two, and three groups of fixed support members are respectively located on both sides of the fixing ring and the end of the base plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] A rapid spark detection device for a PTFE tube is provided with a detection structure. When the PTFE tube moves between a fixed ring and a rotating ring, the outer side of the PTFE tube drives the electrodes to rotate around a connecting block, causing the electrodes to slide on the outer side of the PTFE tube. At this time, a high voltage is applied to the electrodes through an external wire, forming a high-voltage electric field between the multiple electrodes. The high-voltage electric field applies voltage to the surface of the PTFE tube. When tiny cracks on the PTFE tube are detected, current passes through these defects to form sparks, thereby detecting the incomplete part of the PTFE tube.

[0017] Furthermore, a metal cage is provided to form an electromagnetic shielding structure inside the protective shell.

There are many sources of electromagnetic interference in industrial field environments. The electromagnetic shielding provides a relatively clean electromagnetic environment to ensure the stable operation of the equipment.

[0018] Furthermore, during the movement of the PTFE tube inside the base plate, the PTFE tube moves inside the fixed ring and the rotating ring through the support of multiple fixed supports. The pulley provided inside the rotating support is driven by a motor, and the worm gear is driven to rotate by rotating the worm, thereby adjusting the angle of the rotating support on the top of the base plate. When the PTFE tube is located on the top of the rotating support, the pulley inside the rotating support is driven to rotate, so that the pulley drives the PTFE tube to move in a spiral shape on the outside of the rotating support, so that the PTFE tube rotates simultaneously during the translation movement inside the protective shell, thereby making the contact with the outside of the PTFE tube more sufficient during the electric spark detection process.

[0028] A metal cage 4 with a mesh structure is fixedly connected to the inside of the protective shell 2, and the metal cage 4 is respectively connected to the inside of the space formed by the bottom plate 1 and the protective shell 2. A sealing cover 9 is fixedly connected to the outside of the rotating ring 6, and a handle 10 is fixedly connected to the outside of the sealing cover 9, and a magnet 11 is fixedly connected to the end of the sealing cover 9. Wires are provided inside the fixed ring 5 and the rotating ring 6, and one end of the wire extending to the outside of the fixed ring 5 and the rotating ring 6 is fixedly connected to an external wire 12. A slot is provided in the middle of the protective shell 2, and the inside of the slot is snap-connected with the sealing cover 9, and the magnet 11 is located at the joint between the sealing cover 9 and the protective shell 2. Six fixed support members 1 are fixedly connected to the top of the bottom plate 1 3, and the six fixed supports 13 are arranged in groups of two, and the three groups of fixed supports 13 are respectively located on both sides of the fixed ring 5 and the end of the bottom plate 1, the fixed supports 13 are composed of a support rod and a pulley, and the support rod is fixedly connected to the top of the bottom plate 1, and the end of the bottom plate 1 away from the fixed support 13 is rotatably connected to the inside of the bottom plate 1 with a rotating support 14, and the rotating support 14 is provided with two symmetrically distributed on both sides of the top of the bottom plate 1, and the bottom of the rotating support 14 is fixedly connected to a worm gear 15, and the inside of the bottom plate 1 is rotatably connected to a worm 16, and the outer side of the worm 16 is meshed with the outer sides of the two worm gears 15, and the worm 16 extends to the outside of the bottom plate 1 and the protective shell 2;

[0029] When the PTFE tube moves between the fixed ring 5 and the rotating ring 6, the outside of the PTFE tube will drive the electrode 8 to rotate around the connecting block 7, causing the electrode 8 to slide on the outside of the PTFE tube.
