Description

Technical Field

[0001] The invention relates to the technical field of cable connection detection, in particular to a device for detecting abnormal connection of DC cable electrodes. Background Art

[0002] When detecting abnormalities at the electrode connection of a DC cable, an infrared thermal imager is generally used for detection. An infrared thermal imager, also known as a thermal imager, is a device that uses an infrared detector, an optical imaging objective lens, and an optical-mechanical scanning system (or advanced focal plane technology) to receive the infrared radiation energy distribution diagram of the target being measured, and reflect it on the photosensitive element of the infrared detector, and then converts the infrared radiation energy into an electrical signal. After amplification, processing, conversion or standard video signal, the infrared thermal image is displayed on a TV screen or monitor. This device can convert the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured, thereby helping the operator to quickly and accurately determine the heating situation and fault location.

[0003] When the infrared thermal imager is in idle state, its display screen and camera are directly exposed to the air, which will cause a large amount of dust in the air to adhere to the camera and display screen, easily affecting the normal use of the thermal imager. In addition, when the thermal imager is hit, the casing cannot provide comprehensive protection for the camera and display screen, which can easily cause the display screen and camera to break.

[0019] Specifically, the bottom end of the body 1 is fixedly connected to the top end of the handle 2, and the specific shape of the handle 2 is cylindrical. The handle 2 is convenient for the staff to directly grasp the entire thermal imager.

[0020] Specifically, the connection between the connecting rod 7 and the first round rod 6 is located inside the first mounting groove 5. The specific shape of the first mounting groove 5 is a square setting. The top and bottom ends of the connecting rod 7 are arc-shaped settings. The first mounting groove 5 can provide a reasonable rotation space for the connecting rod 7.

[0021] Specifically, the specific shape of the limit block 12 is a semicircular arc, the specific shape of the limit groove 9 is a semicircular arc, the specific shape of the extrusion seat 11 is a triangular shape, and the specific shape of the pressure seat 8 is an inverted triangular shape.

[0023] Specifically, the top of the oblique side of the connecting rod 7 is rotatably connected to the second round rod 19, and the connection between the connecting rod 7 and the second round rod 19 is located inside the second installation groove 18, so that the connecting rod 7 can easily drive the moving seat 17 to move through the second round rod 19.

[0024] Specifically, the body 1 is located at the middle position inside the two protective shells 23 , and the protective shells 23 are convenient for providing protection for the body 1 .

[0025] Specifically, a plurality of vertical grooves 25 arranged in an array are provided on the handle 2 at positions corresponding to the inner portions of the annular groove 3, and vertical blocks 26 are fixedly connected to the positions of the lifting seat 4 corresponding to the vertical grooves 25. The vertical blocks 26 are slidably connected to the inner portions of the vertical grooves 25. The connection between the vertical grooves 25 and the vertical blocks 26 facilitates guiding the movement of the lifting seat 4.

[0026] When in use, the protective shell 23 in the idle state can provide the internal body 1 with the ability to block, impact and prevent falling. When the body 1 needs to be used to perform abnormal detection on the cable electrode connection, the rotating ring 10 can be directly rotated. The rotation of the rotating ring 10 will drive the two extrusion seats 11 to rotate together. The two extrusion seats 11 will rotate toward the pressure-bearing seat 8 respectively. The rotation of the extrusion seats 11 will squeeze the outer wall of the pressure-bearing seat 8, and the squeezed pressure-bearing seat 8 will jointly drive the lifting seat 4 to move upward. The lifting seat 4 will drive the vertical block 26 to move upward inside the annular groove 3. The movement of the vertical block 26 inside the vertical groove 25 can guide the movement of the lifting seat 4. At the same time, the upward movement of the lifting seat 4 will also drive the first round rod 6 to move upward, and the multiple first round rods 6 will all be linked The rod 7 forms an extrusion force. At this time, the connection between the linkage rod 7 and the first round rod 6 will move upward, and the connection between the linkage rod 7 and the first round rod 6 will rotate with the first round rod 6 as the center. At this time, the two pairs of linkage rods 7 opposite to each other will rotate in the direction away from each other. The linkage rod 7 moves upward and acts on the top second round rod 19 when rotating. The connection between the linkage rod 7 and the second round rod 19 will rotate with the second round rod 19 as the center, and the linkage rod 7 will also push each second round rod 19 to move, and each second round rod 19 will drive the moving seat 17 to move, and the moving seat 17 will slide inside the slide groove 15, and the limit rod 16 is the moving guide of the moving seat 17. Each moving seat 17 will jointly drive the rotating rod 20 to move, and the two rotating rods 20 move away from each other. The movement will drive the driven gear 21, the connecting block 22 and the protective shell 23 to move. The driven gear 21 will be connected to the transmission rack 14 during the movement. At this time, the moving driven gear 21 will rotate during the movement due to the transmission rack 14. The two rotating driven gears 21 will drive the rotating rod 20 to rotate. At this time, the two rotating rods 20 will rotate during the movement. The rotating rod 20 will drive the connecting block 22 and the protective shell 23 to rotate. The two protective shells 23 rotate away from each other during the movement to completely expose the body 1. When the protective shell 23 moves and rotates, the rotating ring 10 just drives the extrusion seat 11 and the limit block 12 to rotate the corresponding limit groove 9 bottom end. At this time, the limit groove 9 will be aligned with the limit block 12 connection, can limit the position of lifting seat 4 and rotating ring 10, without strong external force to rotate rotating ring 10, limiting groove 9 and limiting block 12 will not separate, at this time, infrared detection of cable electrode connection can be performed through machine body 1, if temperature abnormality occurs at cable electrode connection, emergency treatment of cable electrode connection is required, when each component needs to be reset, it is necessary to forcefully rotate rotating ring 10, because limiting groove 9 and limiting block 12 are in connection state at this time, it is necessary to rotate rotating ring 10 so that limiting block 12 forces the inner wall of limiting groove 9 to be squeezed, and the diameter of limiting groove 9 is larger than limiting block 12, so the squeezing of limiting block 12 will cause limiting groove 9 and pressure seat to move upward, at this time limiting block 12 is separated from limiting groove 9,The rotating ring 10 can be rotated to the original position, and then the lifting seat 4 is pulled down to return to the original position, and then all components can be reset.
