Description

Technical Field

[0001] The invention relates to the field of rapid collection of electrical traces, in particular to a pair of rapid collection pliers for electrical traces at a fire scene. Background Art

[0002] Measuring the load current of low-voltage overhead lines is an important means of understanding the load distribution in a substation. This primarily involves measuring the current in each branch line, analyzing the data, and identifying users who steal electricity. Furthermore, in remote rural areas, overhead lines are still the primary method of power transmission, and pin-type insulators are widely used. In low winter temperatures, the insulator surface freezes and expands, often causing cracks in the insulator, leading to insulation damage, breakdown discharges, and increased line losses.

[0003] Patent CN216847928U relates to a current detection device for a distribution network. The device aims to overcome the problems of low-voltage overhead line load current measurement methods, such as low efficiency of manual and mechanical coordination, resource waste, and difficulty in detecting faults during routine inspections of concealed low-voltage distribution equipment. The device comprises an insulating rod, a clamp-type current detection device, and a current reading device. The current reading device comprises an image acquisition device and an image receiving device. The clamp-type current detection device and the image acquisition device are fixed to the top of the insulating rod. The image acquisition end of the image acquisition device faces the current display screen of the clamp-type current detection device. The image signal output end of the image acquisition device is electrically connected to the image signal input end of the image receiving device.

[0004] The insulating rod part in the above technology is not easy to control the length, which makes it inconvenient to use when the detection position is too high. In addition, the image receiving device in the above technology is set separately and cannot be used as an integral part with the detection part, which makes it inconvenient to use and needs to be improved. For this reason, we propose a fire scene electrical trace rapid collection clamp. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide an insulating rod that is easy to adjust the height, so as to facilitate the control of the detection height; another purpose of the present invention is to provide an image receiving device that is integrally formed with the image receiving device, so as to facilitate the control of the viewing angle of the image receiving device.

[0006] Technical solution: A fire scene electrical trace rapid collection clamp, comprising a sleeve, an insulating rod slidably connected to the interior of the sleeve, a mounting head fixedly connected to the top end of the insulating rod, an image acquisition device mounted on the inner side of the mounting head, a mounting plate fixedly connected to the outer side wall of the insulating rod and located above the mounting head, and a clamp-type current detection device fixedly connected to the rear end of the mounting plate;

[0007] The outer wall of the sleeve is slidably connected to a ring, a bracket 1 is integrally formed on the left side of the front surface of the ring, and a bracket 2 is integrally formed on the right side of the front surface of the ring. A slide groove 1 is provided on the right side of the bracket 1, and a through slide groove 2 is provided on the right side of the bracket 2. A cylinder is slidably connected to the inner side of the slide groove 1, and a fastening bolt is slidably connected to the inner side of the slide groove 2. The opposite sides of the cylinder and the fastening bolt are jointly fixedly connected with an image receiving device, and a fastening nut is threadedly connected to the outer wall of the fastening bolt.

[0008] Furthermore, a shrinkage box is fixedly connected to the upper right side of the sleeve, a piston plate is slidably connected to the inside of the shrinkage box, a positioning column is fixedly connected to the left side of the piston plate, the right end of the positioning column passes through the inner side of the sleeve, and a conical head is integrally formed.

[0009] Furthermore, a spring is fixedly connected between the piston plate and the shrinkage box.

[0010] Furthermore, a plurality of plug holes are opened on the right side of the outer side wall of the insulating rod, and the left end of the conical head is plugged into the inside of the plug hole located above the right side of the insulating rod.

[0011] Furthermore, the bottom of the sleeve is fixedly connected to a hand-held rod, the outer side wall of the hand-held rod is fixedly connected to an elastic airbag, and a ventilation tube is fixedly connected between the elastic airbag and the shrink box.

[0012] Furthermore, a rubber ring is fixedly connected to the inner side wall of the collar.

[0013] Furthermore, a rocker is fixedly connected to the right side of the fastening nut.

[0014] Beneficial effect: When the device is in use, the extension length can be adjusted by pulling the insulating rod to slide inside the casing, thereby controlling the detection height of the clamp-type current detection device, making it easy to adapt to current detection at different heights and distances;

[0015] The spring squeezes the conical head on the positioning column to be initially locked inside the plug hole. During testing, the elastic airbag on the outside of the handheld rod is squeezed to move the positioning column into the plug hole. This prevents the conical head from being separated from the plug hole due to shaking and other problems during the monitoring process, causing the insulating rod to shrink. This makes the insulating rod more stable when extended for use.

[0016] The image receiving device can slide forward or backward through the provided slide grooves 1 and 2 to adjust the viewing position. At the same time, it can be rotated inside the slide grooves 1 and 2 through the cylinder and the fastening bolts, so that the viewing angle of the image receiving device can be controlled, so that it can be adjusted according to user needs, making viewing more convenient. The ring can be used to slide up and down along the sleeve to facilitate controlling the viewing height of the image receiving device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figure 1-Figure 5 As shown, a fire scene electrical trace rapid acquisition clamp is provided, comprising a sleeve 1, an insulating rod 2 is slidably connected to the interior of the sleeve 1, a mounting head 3 is fixedly connected to the top end of the insulating rod 2, an image acquisition device 4 is mounted on the inner side of the mounting head 3, a mounting plate 5 is fixedly connected to the outer wall of the insulating rod 2 and located above the mounting head 3, and a clamp-type current detection device 6 is fixedly connected to the rear end of the mounting plate 5;

[0026] A collar 7 is slidably connected to the outer wall of the sleeve 1. A bracket 1 8 is integrally formed on the left side of the front surface of the collar 7. A bracket 2 9 is integrally formed on the right side of the front surface of the collar 7. A slide groove 10 is provided on the right side of the bracket 1 8. A through-type slide groove 2 11 is provided on the right side of the bracket 2 9. A cylinder 12 is slidably connected to the inner side of the slide groove 10. A fastening bolt 13 is slidably connected to the inner side of the slide groove 2 11. An image receiving device 14 is fixedly connected to the opposite sides of the cylinder 12 and the fastening bolt 13. A fastening nut 15 is threadedly connected to the outer wall of the fastening bolt 13.

[0027] A shrink box 16 is fixedly connected to the upper right side of the sleeve 1. A piston plate 17 is slidably connected to the interior of the shrink box 16. A positioning column 18 is fixedly connected to the left side of the piston plate 17. The right end of the positioning column 18 passes through the inner side of the sleeve 1 and is integrally formed with a tapered head 19.

[0028] A spring 20 is fixedly connected between the piston plate 17 and the shrink box 16;

[0029] A plurality of insertion holes 21 are provided on the right side of the outer wall of the insulating rod 2. The left end of the conical head 19 is inserted into the insertion hole 21 located on the upper right side of the insulating rod 2.

[0030] The bottom of the sleeve 1 is fixedly connected to a hand-held rod 22, the outer wall of the hand-held rod 22 is fixedly connected to an elastic airbag 23, and a ventilation tube 24 is fixedly connected between the elastic airbag 23 and the shrink box 16;

[0031] When the device is in use, the extension length can be adjusted by pulling the insulating rod 2 to slide inside the sleeve 1, thereby controlling the detection height of the clamp-type current detection device 6, which is convenient for adapting to current detection at different heights and distances. The image acquisition device 4 is used to collect detection data, and the image receiving device 14 is used to receive and display data. This method makes it possible to detect electrical traces more widely.

[0032] After adjusting the height, the spring 20 is used to squeeze the conical head 19 on the positioning column 18 and snap it into the inside of the plug hole 21 for preliminary locking. During testing, the elastic airbag 23 on the outside of the handheld rod 22 is squeezed, so that the gas inside the elastic airbag 23 is filled into the inside of the retraction box 16 through the ventilation tube 24, pushing the piston plate 17 toward the insulating rod 2, and further moving the positioning column 18 to be plugged into the inside of the plug hole 21, preventing the conical head 19 from detaching from the inside of the plug hole 21 due to problems such as shaking during the monitoring process, resulting in the contraction of the insulating rod 2, making the insulating rod 2 more stable when extended for use;

[0033] The image receiving device 14 can slide forward or backward through the provided slide groove 10 and the slide groove 2 11 to adjust the viewing position. At the same time, the cylinder 12 and the fastening bolt 13 can be rotated inside the slide groove 10 and the slide groove 2 11, so that the viewing angle of the image receiving device 14 can be controlled, so that it can be adjusted according to user needs, making viewing more convenient. By rotating the fastening bolt 13, it is positioned close to the bracket 2 9, limiting the forward and backward movement position and rotation viewing angle of the image receiving device 14; and the ring 7 can slide up and down along the sleeve 1 to facilitate control of the viewing height.

[0034] The inner side wall of the collar 7 is fixedly connected with a rubber ring 25;

[0035] Increase the friction between the sleeve 1 and the collar 7 so that after the collar 7 slides to a certain position, it can stay in the current position without being affected by external forces and is not easy to slide;

[0036] The right side of the fastening nut 15 is fixedly connected with a rocker 26;

[0037] The handheld rocker 26 is convenient for driving the fastening nut 15 to rotate.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
