Description

Technical Field

[0001] This invention belongs to the field of power cable technology, and specifically relates to an ultrasonic location and intelligent diagnostic device for internal hidden dangers in power cables. Background Technology

[0002] The ultrasonic positioning and intelligent diagnostic device for internal hazards in power cables is a device used to detect internal faults in cables. It uses ultrasonic technology and intelligent algorithms to accurately locate and diagnose cable hazards. During long-term operation, power cables may develop various internal hazards due to factors such as material aging, environmental factors, installation processes, and load changes. These hazards include partial discharge, insulation aging, and mechanical damage. If these hazards are not detected in time, they may lead to serious accidents such as insulation breakdown, short circuits, or even fires.

[0003] For underground power cables, ultrasonic positioning and intelligent diagnosis are required after a period of use. Existing devices often lack marking components. When potential hazards in the power cable are diagnosed, the parts of the power cable that need repair cannot be marked in time. This makes it difficult for subsequent maintenance personnel to accurately locate the parts of the power cable that need repair, making the operation more complicated, increasing working time and reducing maintenance efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic positioning and intelligent diagnostic device for internal hazards in power cables. Its advantages are that it can facilitate timely marking of power cable sections that need repair, and it can also facilitate the installation and disassembly of the positioning and diagnostic body.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an ultrasonic positioning and intelligent diagnostic device for internal hidden dangers in power cables, comprising a base plate, a bracket welded to the bottom of the base plate, casters rotatably connected to the inner side of the bracket, a handle welded to the rear side of the top of the base plate, a support column welded to the right side of the top of the base plate, a support plate provided on the top of the support column, a positioning diagnostic body bolted to the bottom of the support plate, a display screen bolted to the top of the support plate, a storage box bolted to the left side of the top of the base plate, baffles bolted to the interior of the storage box, the storage box being configured as a first chamber, a second chamber, and a third chamber, a discharge assembly provided on the right side of each of the first, second, and third chambers, an adjustment assembly provided on the right side of the base plate, and a fixing mechanism provided on the top of the support plate.

[0006] The above technical solution allows for the extraction of different colored marking pigments from the first, second, and third chambers based on the potential hazards of the power cable, facilitating quick and accurate assessment by subsequent maintenance personnel.

[0007] The present invention is further configured such that the discharge assembly includes a first connecting pipe, one end of which is fixedly connected to the interior of the first chamber, the second chamber and the third chamber respectively, the other end of which is fixedly connected to a suction pump, the output end of which is fixedly connected to a second connecting pipe, and the other end of which is movably connected to a third connecting pipe.

[0008] By adopting the above technical solution, when a discharge component is set up, different colored marking pigments can be sucked out by the suction pump to mark the part of the power cable that needs repair, thus saving judgment time.

[0009] The present invention is further configured such that the adjusting component includes a fixing plate, the left side of the fixing plate is bolted to the right side of the base plate, three fixing plates are spaced apart, each fixing plate has a symmetrical slot on its right side, each third connecting tube has an ear plate fixedly connected to its surface, each ear plate has a spring fixedly connected to its left side, and the other end of each spring has a locking rod fixedly connected to its other end, the other end of the locking rod engaging with the inside of the slot.

[0010] The above technical solution involves setting an adjustment component that allows the outlet of the third connecting tube to be rotated upwards when the marker pigment falls to the ground, thus avoiding the need to wait for the marker pigment to fall completely and saving waiting time.

[0011] The present invention is further configured such that the fixing mechanism includes a first fixing hole, which is symmetrically opened through the top of the support plate, and a second fixing hole is opened at the top of the support column. The first fixing hole and the second fixing hole are both threadedly connected to a fixing rod, and a knob is fixedly connected to the top of the fixing rod.

[0012] The above technical solution allows for easy installation and disassembly of the positioning diagnostic unit by setting up a fixing mechanism. When not in use, the positioning diagnostic unit can be easily disassembled and collected to prevent damage or dust accumulation.

[0013] The present invention is further configured such that a protective box is bolted to the right side of the top of the base plate, and the surface of the suction pump is bolted to the inside of the protective box.

[0014] The above technical solution involves setting up a protective box to protect the suction pump from damage. The protective box is designed with a metal mesh structure, which extends the service life of the suction pump.

[0015] The invention is further configured such that a sealing door is hinged to the top of the storage bin, and a handle is welded to the top of the sealing door.

[0016] The above technical solution allows for easy opening of the sealed door and facilitates the entry of pigment into the storage bin by setting up a sealed door and a handle.

[0017] The present invention is further configured such that a fixing block is fixedly connected to the other end of each of the third connecting pipes, and a circular groove, a square groove and a pentagonal groove are respectively opened through the bottom of each fixing block.

[0018] By adopting the above technical solution, by setting fixed blocks, circular slots, square slots and pentagonal slots, the marking pigment can present different shapes when it falls on the ground, making it easier to intuitively judge the type of hidden dangers of power cables.

[0019] The invention is further configured such that the surface of the knob is provided with anti-slip texture.

[0020] The above technical solution, by setting anti-slip texture, can prevent hands from slipping and make it easier to rotate the knob.

[0021] In summary, the present invention has the following beneficial effects: 1. This invention, by setting up a discharge component, can use a suction pump to draw out different colored marking pigments to mark the parts of the power cable that need repair when they are diagnosed. This facilitates subsequent maintenance personnel to accurately and quickly determine the condition of the parts, saving judgment time and improving operational efficiency. By setting up an adjustment component, the outlet of the third connecting pipe can be rotated upwards when the marking pigment falls to the ground, avoiding waiting for the marking pigment to fall completely, saving waiting time and improving overall efficiency. If the marking pigment is not waited for to fall completely and the process proceeds directly, the parts of the power cable that do not need repair will also be marked with marking pigment, which is not conducive to the accurate and quick judgment of subsequent maintenance personnel.

[0022] 2. By setting a fixing mechanism, the present invention facilitates the installation and disassembly of the positioning diagnostic body. When not in use, the positioning diagnostic body can be easily disassembled and collected to prevent damage or dust accumulation. This achieves the effect of facilitating the collection, maintenance and repair of the positioning diagnostic body and improving its service life. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 An ultrasonic positioning and intelligent diagnostic device for internal hazards in power cables includes a base plate 1, a bracket 2 welded to the bottom of the base plate 1, casters 3 rotatably connected to the inner side of the bracket 2, a handle 4 welded to the rear side of the top of the base plate 1, a support column 5 welded to the right side of the top of the base plate 1, a support plate 6 mounted on the top of the support column 5, a positioning and diagnostic body 7 bolted to the bottom of the support plate 6, a display screen 8 bolted to the top of the support plate 6, a storage box 9 bolted to the left side of the top of the base plate 1, and baffles bolted to the interior of the storage box 9. The plate 10 and the storage box 9 are configured as a first chamber 1101, a second chamber 1102 and a third chamber 1103. A discharge assembly 12 is provided on the right side of each of the first chamber 1101, the second chamber 1102 and the third chamber 1103. An adjustment assembly 13 is provided on the right side of the bottom plate 1. This allows for the extraction of different colored marking pigments from the first chamber 1101, the second chamber 1102 and the third chamber 1103 according to the potential hazards of the power cable, facilitating quick and accurate judgment by subsequent maintenance personnel.

[0027] refer to Figure 3The discharge assembly 12 includes a first connecting pipe 1201. One end of the first connecting pipe 1201 is fixedly connected to the interior of the first chamber 1101, the second chamber 1102, and the third chamber 1103, respectively. The other end of the first connecting pipe 1201 is fixedly connected to a suction pump 1202. The output end of the suction pump 1202 is fixedly connected to a second connecting pipe 1203. The other end of the second connecting pipe 1203 is movably connected to a third connecting pipe 1204. By setting the discharge assembly 12, when a section of the power cable that needs repair is diagnosed, different colored marking pigments can be drawn out by the suction pump 1202 to mark the section, saving judgment time.

[0028] refer to Figure 3 The adjusting component 13 includes a fixing plate 1301. The left side of the fixing plate 1301 is bolted to the right side of the base plate 1. Three fixing plates 1301 are spaced apart. Each fixing plate 1301 has a symmetrical slot 1302 on its right side. Each third connecting tube 1204 has an ear plate 1303 fixedly connected to its surface. Each ear plate 1303 has a spring 1304 fixedly connected to its left side. Each spring 1304 has a locking rod 1305 fixedly connected to its other end. The other end of the locking rod 1305 engages with the inside of the slot 1302. By setting the adjusting component 13, when the marking pigment falls to the ground, the outlet of the third connecting tube 1204 can be rotated upward, avoiding waiting for the marking pigment to fall completely and saving waiting time.

[0029] refer to Figure 1 A protective box 15 is bolted to the right side of the top of the base plate 1. The surface of the suction pump 1202 is bolted to the inside of the protective box 15. By setting the protective box 15, the suction pump 1202 can be protected and prevented from being damaged. The protective box 15 is set with a metal mesh structure to extend the service life of the suction pump 1202.

[0030] refer to Figure 1 The top of the storage bin 9 is hinged with a sealing door 16, and a handle 17 is welded to the top of the sealing door 16. By setting the sealing door 16 and the handle 17, the sealing door 16 can be opened easily, making it easier to add pigment into the storage bin 9.

[0031] refer to Figure 3 and Figure 4 Each third connecting pipe 1204 has a fixed block 18 fixedly connected to the other end. Each fixed block 18 has a circular slot 1901, a square slot 1902, and a pentagonal slot 1903 through the bottom. By setting the fixed block 18, the circular slot 1901, the square slot 1902, and the pentagonal slot 1903, the marking pigment can present different shapes when it falls on the ground, making it easier to intuitively judge the type of hidden danger of the power cable.

[0032] Brief description of the usage process: Different colored marking pigments are installed in the first chamber 1101, the second chamber 1102 and the third chamber 1103 respectively. The positioning and diagnostic body 7 diagnoses the potential hazards of the power cable and displays them on the display screen 8. After the staff sees this, they start different suction pumps 1202 respectively. The suction pump 1202 sucks the marking pigment into the second connecting pipe 1203 through the first connecting pipe 1201. The marking pigment flows into the third connecting pipe 1204 along the second connecting pipe 1203 and falls to the ground from the third connecting pipe 1204. At this time, there may be residual marking pigment in the third connecting tube 1204. If we wait for the marking pigment to fall off, it will prolong the waiting time and reduce the overall work efficiency. If we do not wait for the marking pigment to fall off and continue the diagnosis directly, the marking pigment will appear on the power cable parts that do not need to be repaired, which is not conducive to subsequent repairs. Pull the lever 1305, the spring 1304 is compressed, so that the lever 1305 is disengaged from the slot 1302. Rotate the third connecting tube 1204 until the outlet of the third connecting tube 1204 is facing upward. Release the lever 1305, the spring 1304 returns to its original position, so that the lever 1305 is engaged with the slot 1302.

[0033] Example 2: refer to Figure 1 An ultrasonic positioning and intelligent diagnostic device for internal hazards in power cables is provided. The top of the support plate 6 is equipped with a fixing mechanism 14, which facilitates the collection, maintenance and repair of the positioning and diagnostic body 7, and improves its service life.

[0034] refer to Figure 2 and Figure 3 The fixing mechanism 14 includes a first fixing hole 1401, which is symmetrically opened through the top of the support plate 6. A second fixing hole 1402 is opened at the top of the support column 5. The first fixing hole 1401 and the second fixing hole 1402 are both threadedly connected to a fixing rod 1403. A knob 1404 is fixedly connected to the top of the fixing rod 1403. By setting the fixing mechanism 14, it is easy to install and disassemble the positioning diagnostic body 7. When not in use, it is easy to disassemble and collect the positioning diagnostic body 7 to prevent it from being damaged or falling into dust.

[0035] refer to Figure 2 The surface of knob 1404 is provided with anti-slip texture, which can prevent the hand from slipping and make it easy to rotate knob 1404.

[0036] Brief description of the usage process: Rotate the knob 1404 to disengage the fixing rod 1403 from the first fixing hole 1401 and the second fixing hole 1402. At this time, the support plate 6 will separate from the support column 5, making it easy to remove the support plate 6, so that the positioning diagnostic body 7 and the display screen 8 can be removed.

[0037] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
