Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of live detection equipment, and specifically relates to a high-safety live detection device for power equipment. Background Art
[0002] A power equipment detection device refers to an instrument for testing, verifying, detecting, and accepting equipment for power production and power grid operation. It provides reliable guarantees for the safety and reliability of power operation. When a fault occurs in the power grid, people use the power equipment detection device for on-site detection to ensure the normal operation of the power grid. Live working detection tests usually include devices such as an insulating measuring rod for measuring length or distance, a surface leakage current meter, a hygrometer, an electroscope, a voltage detection system, a voltage indicating device, a phase detector for determining the phase of the power supply, an indicator for indicating the working voltage, and a contact electrode for forming an electrical connection with the circuit element to be tested.
[0003] In the existing live detection device, during use, for the overhead power grid cable, when taking live detection, the control arm of the live detection device installed on the detection vehicle is usually used to send the detection joint and the detection personnel into the air and perform live detection on the suspended cable. However, in the actual detection process, manual operation in the air is required. Affected by the professional ability level of the detection workers and the failure probability of safety equipment, the detection workers in the air are at risk of moving and falling. Moreover, when performing live detection on the cable manually, affected by the cable leakage, there is also a risk of electric shock in the actual detection process. The actual detection safety is poor and the use effect is not good.
[0004] In addition, in the existing live detection device, during use, since the detection of cable information is involved when detecting the suspended cable, when measuring the distance between the cables to be measured, a marking rod is usually used for control detection. However, affected by the height, the actual marking rod is far away during detection and cannot be clearly observed underground. It is difficult to obtain the distance measurement result clearly and conveniently, and the actual measurement data acquisition effect is not good. Summary of the Invention
[0005] The purpose of the present invention is to provide a high-safety live detection device for power equipment to solve the problems raised in the above background art.
[0006] To achieve the above object, the present invention provides the following technical solution: A live detection device for high - security power equipment, including a control arm. A connecting seat is fixedly installed on the top surface of the control arm. A fixing frame is fixedly installed on the end face of the connecting seat. A fixing tube is provided on the inner surface of the fixing frame. A connecting block is fixedly connected to the bottom surface of the fixing tube, and the bottom surface of the connecting block is fixedly connected to the fixing frame. An intermediate plate is fixedly sleeved inside the fixing tube. A curved rod is movably sleeved on the inner surface of the fixing tube. A movable plug is fixedly connected to the inner end face of the curved rod. A baffle is fixedly connected to the outer end face of the curved rod. A limiting plate and a detection plate are respectively fixedly connected to the outer side surface of the baffle. An inner groove is formed on the top surface of the baffle. A second lifting rod is fixedly installed inside the inner groove. A connecting rod is fixedly connected to the top surface of the second lifting rod. A detection plate is fixedly installed on the bottom surface of the connecting rod. A connecting wire is fixedly connected between the detection plate and the detection box. A fixing box is fixedly installed on the front surface of the control arm. A communicating pipe is fixedly connected and communicated between the fixing box and the fixing tube. A threaded rod is threadedly sleeved on the end face of the fixing box. A sealing plug is fixedly connected to the inner end of the threaded rod, and the sealing plug is movably sleeved inside the fixing box.
[0007] First Embodiment: As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, when cable live detection is required, move the control arm installed on the detection vehicle below the cable and start the control arm, so that the control arm moves the connecting seat upward, and make the two baffles at the top of the fixing frame located between the two cables, and make the limiting plates on the baffles located below the cables. Rotate the threaded rods on the two fixing boxes respectively. As the threaded rods rotate and move horizontally, drive the sealing plugs fixed on the inner end faces of the threaded rods to rotate and move horizontally in the fixing boxes. As the sealing plugs rotate and move horizontally, squeeze the pressure oil in the fixing boxes upward, so that the pressure oil in the fixing boxes is conveyed to the inside of the fixing tube through the communicating pipe. As the pressure oil is continuously squeezed into the fixing tube, the pressure oil in the fixing tube pushes the movable plug to move, thereby driving the curved rod to move outward. As the curved rod moves, the baffle connected to the outer end face of the curved rod slides, making the baffle gradually approach the cable, and making the cable contact the outer side surface of the baffle. Then stop adjusting one side, continue to rotate and adjust the threaded rod on the other side, so that the other baffle contacts the cable. Then start the second lifting rod, so that the second lifting rod drives the connecting rod to move downward, thereby making the detection plate move downward to press the cable into the limiting plate. Then start the detection box to conduct live detection; when both cables contact the baffles, observe the moving position of the sealing plug in the fixing box made of transparent material and match it with the scale grooves on the front surface of the fixing box, read the values on the two scale grooves, and perform cumulative calculation to obtain the distance between the two measured cables.
[0008] First, by using a baffle plate movably installed at the top of the fixed frame and adding a fixed pipe in the fixed frame, the curved rod in the fixed pipe is connected to the baffle plate. By rotating the threaded rod to push the pressure oil in the fixed box, the pressure oil enters the fixed pipe through the connecting pipe and pushes the curved rod on one side to move, thereby causing the baffle plate to move. When the baffle plate moves into contact with the cable, the second lifting rod is used to lower the detection plate and press the cable into the inner part of the limit plate. Cooperating with the detection box and the magnetic detection device on the detection plate, the live detection under insulation is completed. During the detection process, manual high-altitude detection is avoided, the situation of personnel falling is avoided, mechanized detection is completed, and the potential safety hazard caused by electric leakage is avoided, with high use safety.
[0009] In addition, by opening a scale groove on the front surface of the fixed box and connecting the fixed pipe and the fixed box through the connecting pipe, using the flowing effect of the pressure oil, the curved rod is pushed to move by squeezing the pressure oil, thereby realizing the movement of the baffle plate. When the baffle plate contacts the cable, the inflow volume of the pressure oil can be obtained. Cooperating with the linear change of the pressure oil in the fixed box, distance conversion can be carried out, and the distance between two groups of cables can be measured under low-altitude operation, avoiding the aerial operation of the detection workers, reducing the actual detection difficulty, with simple operation and good use effect.
[0010] Preferably, a threaded hole is opened on the end face of the fixed box, and the inner surface of the threaded hole is threadedly sleeved with the threaded rod. A scale groove is opened on the front surface of the fixed box. By using the scale groove, the equal-proportion conversion of the movement amount of the pressure oil in the fixed box and the actual movement amount of the baffle plate is carried out, so that the actual distance between the cables can be obtained by accumulating the readings of the two groups of scale grooves.
[0011] Preferably, the number of the connecting pipes is two, and the two connecting pipes are symmetrically distributed on the left and right sides of the fixed pipe. The pressure oil is conveyed into the fixed pipe by using the connecting pipes, and the two groups of connecting pipes are separately controlled to avoid the symmetrical influence caused by simultaneous control.
[0012] Preferably, a fixed ring is fixedly sleeved on the outer surface of the curved rod, one end of a spring is fixedly connected to the side surface of the fixed ring, and the other end of the spring is fixedly connected to the fixed pipe. By using the elasticity of the spring, it is ensured that the curved rod can be conveniently reset during the process of resetting the threaded rod.
[0013] Preferably, the control arm includes a mounting seat, a control box and a first lifting rod. The control box is fixedly installed on the top surface of the mounting seat, the first lifting rod is fixedly installed on the top surface of the control box, and the top surface of the first lifting rod is fixedly connected to the connecting seat. By using the first lifting rod in the control arm to conveniently control the actual position, and the control arm is installed in the carriage of the detection vehicle, it is convenient to move and adjust to the target position for detection.
[0014] Preferably, a chute is provided on the top surface of the fixed frame, and a sliding plate is movably sleeved on the inner surface of the chute. The top surface of the sliding plate is fixedly connected to the baffle. By utilizing the movable sleeving of the chute and the sliding plate, both the baffle and the curved rod have a stable lateral movement effect, avoiding deflection.
[0015] Preferably, a drying mechanism is fixedly installed on the inner side surface of the baffle. The drying mechanism includes side plates, arc grooves, heating pipes, and small holes. The side plates are fixedly connected to the inner side surface of the baffle. The arc grooves are provided on the side surfaces of the side plates. The heating pipes are fixedly installed inside the side plates. The small holes are provided inside the arc grooves, and the small holes communicate with the inner cavity of the side plates. By using the arc grooves to limit the positions of the small holes, it is avoided that the melted snow water and ice water flow back into the inside of the side plates, and the heating pipes are used in cooperation with the small holes to achieve efficient drying of the cable, realizing live detection in winter.
[0016] Preferably, the number of both the curved rods and the movable plugs is two, and the two curved rods and the movable plugs are symmetrically distributed on both sides of the middle plate. By using the two groups of curved rods and movable plugs symmetrically distributed on both sides of the middle plate, the two groups of curved rods are controlled separately, ensuring that the baffle can be finally adjusted to just contact the cable at any position below the two groups of cables.
[0017] Preferably, the cross-section of the limiting plate is L-shaped, and the detection plate is located above the limiting plate, making it convenient for the detection plate to be sleeved inside the limiting plate when moving downward, improving the limiting effect of the cable and the detection effect at the same time.
[0018] Second Embodiment: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 shown, during winter detection, the control arm is used to control the fixed frame to move below a group of cables. By rotating the threaded rod, the pressure oil in the fixed box is squeezed into the fixed pipe through the connecting pipe. As the pressure oil is introduced into the fixed pipe, the curved rod is pushed to move outward. As the spring is compressed, the curved rod drives the distance between the two baffles to increase. After the distance between the two baffles increases, the control arm is operated again to make the two baffles located on the left and right sides below the cable, and then rise after moving, so that the cable is located between the two drying mechanisms. The threaded rod is gradually rotated to make the baffle gradually reset, and the cable is placed between the two drying mechanisms. The heating pipe in the drying mechanism is started, and the heat in the side plate radiates to the surface of the cable through the small holes, melting the snow and ice on the surface of the cable and gradually drying the local part of the cable. After drying, the detection operation can be carried out again.
[0019] First, by fixedly installing a drying mechanism on the inner side of the baffle plate, and through operating the control arm and adjusting the threaded rod, the cable is located between two groups of drying mechanisms. The heating tubes in the drying mechanism cooperate with the small holes to melt the snow and ice on the surface area of the cable. During the winter use process, rapid drying treatment is carried out, and live detection is carried out after the treatment, greatly improving the actual detection effect in winter. The cable drying is convenient and the operation is simple.
[0020] The beneficial effects of the present invention are as follows:
[0021] 1. In the present invention, by using the baffle plate movably installed on the top of the fixed frame, and adding a fixed tube in the fixed frame, the curved rod in the fixed tube is connected to the baffle plate. By rotating the threaded rod to push the pressure oil in the fixed box, the pressure oil enters the fixed tube through the connecting pipe and pushes the curved rod on one side to move, so as to move the baffle plate. When the baffle plate moves to contact the cable, the second lifting rod is used to make the detection plate move down and press the cable into the inside of the limit plate. Cooperating with the detection box and the magnetic detection equipment on the detection plate, the live detection under insulation is completed. During the detection process, manual high-altitude detection is avoided, and the situation of personnel falling is avoided. While completing the mechanized detection, the potential safety hazard caused by electric leakage is avoided, and the use safety is high.
[0022] 2. In the present invention, a scale groove is opened on the front surface of the fixed box, and the fixed tube and the fixed box are connected through the connecting pipe. By using the flow effect of the pressure oil, the curved rod is pushed to move by squeezing the pressure oil, so as to realize the movement of the baffle plate. When the baffle plate contacts the cable, the inflow amount of the pressure oil can be obtained. Cooperating with the linear change of the pressure oil in the fixed box, distance conversion can be carried out, and the distance measurement between two groups of cables can be completed under low-altitude operation, avoiding the aerial operation of the detection workers, reducing the actual detection difficulty, with simple operation and good use effect.
[0023] 3. In the present invention, by fixedly installing a drying mechanism on the inner side of the baffle plate, and through operating the control arm and adjusting the threaded rod, the cable is located between two groups of drying mechanisms. The heating tubes in the drying mechanism cooperate with the small holes to melt the snow and ice on the surface area of the cable. During the winter use process, rapid drying treatment is carried out, and live detection is carried out after the treatment, greatly improving the actual detection effect in winter. The cable drying is convenient and the operation is simple. Description of the Drawings

A fixed tube 5 is provided on the inner surface of the fixed frame 3. A connection block 6 is fixedly connected to the bottom surface of the fixed tube 5. The bottom surface of the connection block 6 is fixedly connected to the fixed frame 3. An intermediate plate 16 is fixedly sleeved inside the fixed tube 5. A curved rod 7 is movably sleeved on the inner surface of the fixed tube 5. A movable plug 17 is fixedly connected to the inner end face of the curved rod 7. A baffle 9 is fixedly connected to the outer end face of the curved rod 7. A limiting plate 10 and a detection plate 11 are respectively fixedly connected to the outer side surface of the baffle 9. An inner groove 12 is opened on the top surface of the baffle 9. A second lifting rod 13 is fixedly installed inside the inner groove 12. A connecting rod 14 is fixedly connected to the top surface of the second lifting rod 13. A detection plate 11 is fixedly installed on the bottom surface of the connecting rod 14. A connecting wire 27 is fixedly connected between the detection plate 11 and the detection box 4. A fixed box 20 is fixedly installed on the front surface of the control arm 1. A communicating pipe 26 is fixedly communicated between the fixed box 20 and the fixed tube 5. A threaded rod 21 is threadedly sleeved on the end face of the fixed box 20. A sealing plug 22 is fixedly connected to the inner end of the threaded rod 21. The sealing plug 22 is movably sleeved inside the fixed box 20.
[0034] First Embodiment: As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, when cable live detection is required, the control arm 1 installed on the detection vehicle is moved under the cable, and the control arm 1 is started, so that the control arm 1 moves the connecting seat 2 upward, and the two groups of baffles 9 on the top of the fixed frame 3 are located between the two groups of cables, and the limiting plates 10 on the baffles 9 are located below the cables. The threaded rods 21 on the two groups of fixed boxes 20 are rotated respectively. As the threaded rods 21 rotate and move horizontally, the sealing plugs 22 fixed on the inner end faces of the threaded rods 21 rotate and move horizontally in the fixed boxes 20. As the sealing plugs 22 rotate and move horizontally, the pressure oil in the fixed boxes 20 is squeezed upward, so that the pressure oil in the fixed boxes 20 is conveyed into the interior of the fixed pipe 5 through the communicating pipe 26. As the pressure oil is continuously squeezed into the fixed pipe 5, the pressure oil in the fixed pipe 5 pushes the movable plug 17 to move, thereby driving the curved rod 7 to move outward. As the curved rod 7 moves, the baffle 9 connected to the outer end face of the curved rod 7 slides, so that the baffle 9 gradually approaches the cable, and the cable contacts the outer side face of the baffle 9. Then, the adjustment of one side is stopped, and the threaded rod 21 on the other side with the adjusted amount is continuously rotated, so that the other baffle 9 contacts the cable. Then, the second lifting rod 13 is started, so that the second lifting rod 13 drives the connecting rod 14 to move downward, thereby moving the detection plate 11 downward to press the cable into the limiting plate 10. Then, the detection box 4 is started for live detection; when both groups of cables contact the baffle 9, observe the moving position of the sealing plug 22 in the transparent fixed box 20, match it with the scale grooves 23 on the front of the fixed box 20, read the values on the two groups of scale grooves 23, and perform cumulative calculation to obtain the distance between the two measured cables.
[0035] First, by using the baffle 9 movably installed on the top of the fixed frame 3 and adding a fixed pipe 5 in the fixed frame 3, the curved rod 7 in the fixed pipe 5 is connected to the baffle 9. By rotating the threaded rod 21 to push the pressure oil in the fixed box 20, the pressure oil enters the fixed pipe 5 through the communicating pipe 26 and pushes the curved rod 7 on one side to move, thereby causing the baffle 9 to move. When the baffle 9 moves to contact the cable, the second lifting rod 13 is coordinated to move the detection plate 11 downward and press the cable into the limiting plate 10. In cooperation with the detection box 4 and the magnetic detection device on the detection plate 11, live detection under insulation is completed. During the detection process, manual high-altitude detection is avoided, the situation of personnel falling is avoided, while mechanized detection is completed, the potential safety hazard caused by electric leakage is avoided, and the use safety is high.
[0036] In addition, by opening a scale groove 23 on the front surface of the fixed box 20 and connecting the fixed pipe 5 and the fixed box 20 through a connecting pipe 26, using the flowing effect of the pressure oil, the curved rod 7 is pushed to move by extruding the pressure oil, so as to realize the movement of the baffle 9. When the baffle 9 contacts the cable, the inflow of the pressure oil can be obtained. By matching the linear change of the pressure oil in the fixed box 20, the distance conversion can be carried out, and the distance between two groups of cables can be measured under low-altitude operation, avoiding the aerial operation of the detection workers, reducing the actual detection difficulty, with simple operation and good use effect.
[0037] Among them, a threaded hole 24 is opened on the end face of the fixed box 20, and the inner surface of the threaded hole 24 is threadedly sleeved with a threaded rod 21. A scale groove 23 is opened on the front surface of the fixed box 20. By using the scale groove 23, the equal-proportion conversion of the movement amount of the pressure oil in the fixed box 20 and the actual movement amount of the baffle 9 is carried out, so that the accumulated value of the readings of the two groups of scale grooves 23 is used to obtain the actual distance between the cables.
[0038] Among them, the number of the connecting pipes 26 is two, and the two connecting pipes 26 are symmetrically distributed on the left and right sides of the fixed pipe 5. The pressure oil is conveyed into the interior of the fixed pipe 5 by using the connecting pipes 26, and the two groups of connecting pipes 26 are separately controlled to avoid the symmetric influence caused by simultaneous control.
[0039] Among them, a fixed ring 18 is fixedly sleeved on the outer surface of the curved rod 7. One end of a spring 19 is fixedly connected to the side surface of the fixed ring 18, and the other end of the spring 19 is fixedly connected to the fixed pipe 5. By using the elasticity of the spring 19, it is ensured that the curved rod 7 can be conveniently reset during the process of resetting the threaded rod 21.
[0040] Among them, the control arm 1 includes a mounting seat 101, a control box 102 and a first lifting rod 103. The control box 102 is fixedly installed on the top surface of the mounting seat 101, the first lifting rod 103 is fixedly installed on the top surface of the control box 102, and the top surface of the first lifting rod 103 is fixedly connected to the connecting seat 2. By using the first lifting rod 103 in the control arm 1, the actual position is conveniently controlled, and the control arm 1 is installed in the carriage of the detection vehicle, so that it is convenient to move and adjust to the target position for detection.
[0041] Among them, a sliding groove 25 is opened on the top surface of the fixed frame 3, and a sliding plate 8 is movably sleeved on the inner surface of the sliding groove 25. The top surface of the sliding plate 8 is fixedly connected to the baffle 9. By using the movable sleeve connection of the sliding groove 25 and the sliding plate 8, both the baffle 9 and the curved rod 7 have a stable lateral movement effect, avoiding the situation of deflection.
[0042] Among them, a drying mechanism 15 is fixedly installed on the inner side of the baffle 9. The drying mechanism 15 includes side plates 151, arc grooves 152, heating pipes 153 and small holes 154. The side plates 151 are fixedly connected to the inner side of the baffle 9. The arc grooves 152 are formed on the sides of the side plates 151. The heating pipes 153 are fixedly installed inside the side plates 151. The small holes 154 are formed inside the arc grooves 152. The small holes 154 communicate with the inner cavity of the side plates 151. By using the arc grooves 152 to limit the positions of the small holes 154, the melted snow water and ice water are prevented from flowing back into the inside of the side plates 151, and the heating pipes 153 are used in cooperation with the small holes 154 to achieve efficient drying of the cable and realize live detection in winter.
[0043] Among them, the number of the curved rods 7 and the movable plugs 17 is two each. The two curved rods 7 and the movable plugs 17 are symmetrically distributed on both sides of the middle plate 16. By using the two groups of curved rods 7 and the movable plugs 17 symmetrically distributed on both sides of the middle plate 16, the two groups of curved rods 7 are controlled separately to ensure that the baffle 9 can be finally adjusted to just contact the cable at any position below the two groups of cables.
[0044] Among them, the cross-section of the limit plate 10 is L-shaped, and the detection plate 11 is located above the limit plate 10, so that when the detection plate 11 moves downward, it is convenient to be sleeved inside the limit plate 10, improving the limit effect of the cable and the detection effect at the same time.
[0045] Second Embodiment: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 shown, during winter detection, the control arm 1 is used to move the fixed frame 3 below a group of cables. By rotating the threaded rod 21, the pressure oil in the fixed box 20 is squeezed into the fixed pipe 5 through the connecting pipe 26. As the pressure oil is introduced into the fixed pipe 5, the curved rod 7 is pushed to move outward. As the spring 19 is compressed, the curved rod 7 drives the distance between the two baffles 9 to increase. After the distance between the two baffles 9 increases, the control arm 1 is operated again to make the two baffles 9 located on the left and right sides below the cable and rise after moving, so that the cable is located between the two drying mechanisms 15. The threaded rod 21 is gradually rotated to make the baffle 9 gradually reset and place the cable between the two drying mechanisms 15. The heating pipe 153 in the drying mechanism 15 is started, and the heat in the side plate 151 radiates to the surface of the cable through the small holes 154, melting the snow and ice on the surface of the cable and gradually drying the local part of the cable. After drying, the detection operation can be carried out again.
[0046] First, by fixedly installing the drying mechanism 15 on the inner side of the baffle 9 and operating and adjusting the threaded rod 21 through the operation control arm 1, the cable is positioned between the two drying mechanisms 15. The heating tube 153 in the drying mechanism 15 cooperates with the small holes 154 to melt the snow and ice on the surface area of the cable. During winter use, rapid drying treatment is carried out, and live detection is performed after the treatment, greatly improving the actual winter detection effect. The cable drying is convenient and the operation is simple.
