Due to the complex environment of the mine and the dense distribution of cables, when using ordinary clamp ammeters for detection, the magnetic field of the surrounding cables can easily interfere with the detection circuit, thereby affecting the accuracy and reliability of the detection data, making it difficult to accurately judge the circuit condition of the target cable. In addition, the line of sight conditions in mines are usually poor. In the large-scale circuit detection process, if there is a lack of effective marking methods, it is very easy to repeat the detection or miss key detection points. This will not only reduce the detection efficiency, but also may cause circuit safety hazards due to detection loopholes, posing a serious threat to the safety and stability of the entire mine operation.

DETAILED DESCRIPTION

[0025] like Figures 1 to 6 As shown, the present invention provides a mining circuit detection instrument, including: a clamp ammeter 1, a button 2 is installed in the middle of the left side of the clamp ammeter 1, a first clamp head 4 is fixedly connected above the button 2, a second clamp head 14 is fixedly connected to the upper right side of the clamp ammeter 1, a first support rod 3 is slidably connected above the first clamp head 4, and a second support rod 13 is slidably connected above the second clamp head 14, a fluorescent paint marking structure is fixedly connected to the front side of the bottom of the clamp ammeter 1, and a fluorescent paint supplementing structure is fixed to one side of the fluorescent paint marking structure.

[0026] A support rod opening mechanism is arranged inside the first clamp head 4 and the second clamp head 14. The support rod opening mechanism includes a first movable plate 9 rotatably connected to the lower right side of the button 2, the other end of the first movable plate 9 is rotatably connected to a rack plate 19, the rack plate 19 is slidably connected inside the clamp ammeter 1, the rack plate 19 is meshedly connected to a gear 20, a rotating shaft 17 is fixedly connected in the middle of the gear 20, a disk 15 is fixedly connected to the top of the rotating shaft 17, a first support plate 10 is fixedly connected to the front side of the disk 15, the other end of the first support plate 10 is rotatably connected to a second movable plate 18, and the other end of the second movable plate 18 is rotatably connected to the first support rod 3; the rear side of the disk 15 is fixedly connected to a second support plate 11, the other end of the second support plate 11 is rotatably connected to the first movable plate 12, and the other end of the first movable plate 12 is rotatably connected to the second support rod 13. Through the rotational connection of multiple components, the gradual conversion of the motion form and the effective distribution and transmission of force in different directions are realized. Furthermore, the first clamp head 4 and the second clamp head 14 can be opened and closed synchronously, thereby ensuring the stability and accuracy of the entire clamp structure when clamping the object to be measured.

[0027] The fluorescent paint marking structure includes a fixed box 5, a marking tube 25 is fixedly connected to the left side of the fixed box 5, and a nozzle 8 is fixedly connected to the front end of the marking tube 25, which can mark the detected cable, so as to avoid repeated detection or missing certain key detection points when the mine visibility is poor.

[0028] A rotating disk 21 is fixedly connected to the bottom of the rotating shaft 17, a fixed column 22 is fixedly connected to the side of the bottom of the rotating disk 21 away from the center of the circle, a pull-push plate 23 is rotatably connected to the fixed column 22, a piston 24 is rotatably connected to the other end of the pull-push plate 23, a movable disk 27 is fixedly connected to the other end of the piston 24, and the movable disk 27 is slidably connected to the inside of the marking tube 25. The detection function and the marking function are organically combined through a common power source, i.e., the rotating shaft 17, and a series of transmission components.

[0029] A fluorescent paint box 6 as a fluorescent paint supplement structure is fixedly connected to the right side of the front side of the fixed box 5, and a feed pipe 28 is fixedly connected to the discharge port of the fluorescent paint box 6, and the other end of the feed pipe 28 is fixedly connected to the inside of the marking tube 25. The sustainability of the marking function is guaranteed, and the conveying path of the paint in the entire device is also determined.

[0030] A one-way valve 26 is provided on the feed pipe 28 to prevent the fluorescent paint from flowing back after entering the marking tube 25 and affecting the use. A feed cover 7 is provided at the feed port of the fluorescent paint box 6 to facilitate adding paint to the fluorescent paint box 6.

[0031] A spring 16 is fixedly connected to the upper right side of the button 2, and the other end of the spring 16 is fixedly connected to the inside of the clamp ammeter 1, so that the button 2 can be reset conveniently.

[0032] The outer shell of the clamp ammeter 1 is wrapped with an explosion-proof layer and an insulating layer. The explosion-proof layer can effectively prevent explosion accidents caused by electric sparks due to circuit failures, which is particularly critical in underground environments containing flammable gases or dust, and avoids explosion hazards caused by problems with the detection instrument itself. The insulating layer further ensures the safety of the operator and prevents the risk of electric shock. Even in a humid or complex underground electrical environment, it can effectively block the current and ensure the electrical isolation of the operator from the internal circuit.

[0033] The working principle of the present invention is as follows:

[0034] First, during the test, align the cable to be tested and press the button 2. The first movable plate 9 connected to the lower right side of the button 2 will rotate accordingly, pushing the rack plate 19 to slide inside the clamp ammeter 1, driving the gear 20 to rotate, and the shaft 17 will also rotate accordingly. The disc 15 will rotate with the shaft 17, causing the first support plate 10 and the second support plate 11 to move in opposite directions, respectively driving the second movable plate 18 and the first movable plate 12 to move, so that the first support rod 3 and the second support rod 13 are drawn out and the surrounding cables are pushed open to prevent the magnetic field of the surrounding cables from affecting the test results. At this time, release the button 2, and the first support rod 3 and the second support rod 13 are retracted into the first clamp head 4 and the second clamp head 14, so that the use space is reduced when not in use, which is convenient for storage. At the same time, when the button 2 is pressed and released, the shaft 17 is rotated, driving the turntable 21 to rotate, so that the fixed column 22 moves around the center of the turntable 21, driving the push-pull plate 23 to move, so that when the button 2 is pressed, the piston 24 and the movable disk 27 are pulled outward, and the fluorescent paint inside the fluorescent paint box 6 is drawn into the marking tube 25 through the feed pipe 28. When the button 2 is released, the piston 24 and the movable disk 27 push back, and the fluorescent paint is sprayed out through the nozzle 8 to mark the detected cable, so that when the visibility in the mine is poor, repeated detection or omission of certain key detection points can be avoided, and during daily detection, a color usage plan can be formulated, such as using red on Monday, blue on Tuesday, and green on Wednesday, etc. In this way, when checking the cable markings later, the approximate detection date range can be quickly determined by color, which is convenient for distinguishing the detection conditions at different times, ensuring that the detection work is not missed and there is no violation, and ensuring that the entire underground circuit detection operation is in a safe and orderly state.
