Description

Technical Field

[0001] The invention belongs to the technical field of drop-out fuses, and in particular relates to an intelligent monitoring device for drop-out fuses. Background Art

[0002] The drop-out fuse is the most commonly used short-circuit protection switch for 10kV distribution line branch lines and distribution transformers. Because it has an obvious disconnection point and has the function of an isolating switch, it creates a safe working environment for the maintenance section lines and equipment.

[0003] The invention with publication number CN108896864B proposes an online monitoring system for drop-out fuses, which includes a knife switch status monitoring device, a cloud data platform and a mobile terminal. The knife switch status monitoring device establishes a data link with the cloud data platform through an Internet of Things network, and the mobile terminal establishes a data link with the cloud data platform through the Internet. The mobile terminal has a built-in satellite positioning device, which can grasp the operating status of the fuse in real time and send the monitored fuse status information to the cloud data platform.

[0004] However, in the actual monitoring process of the drop-out fuse, the above detection system lacks a mechanical carrier device to automatically trigger the monitoring system. The detection system used for monitoring has poor adaptability to the environment. Summary of the invention

[0005] The object of the present invention is to provide an intelligent monitoring device for a drop-out fuse to solve the monitoring and adaptation strength problems in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An intelligent monitoring device for a drop-out fuse includes an insulator, wherein a buckle head is provided at the upper end of the insulator, a fuse tube is installed at the bottom of the insulator, an operating ring is provided on the fuse tube, a bracket is installed at the bottom end of the insulator, and a first rotating plate and a second rotating plate are hingedly installed on both sides of the bracket;

[0008] A mounting end is provided on one side of the first rotating plate, a screw is connected to the mounting end and the second rotating plate, a connecting rod is rotatably mounted on the screw, a corner plate is provided below the connecting rod, a monitoring component is provided above the connecting rod, and the monitoring component is supported behind the fuse tube;

[0009] The bottom end of the first rotating plate is provided with a tail plate, the side of the tail plate is provided with a bridge plate, both ends of the bridge plate are provided with side ears, wherein the side ears are installed on the tail plate and the second rotating plate, and the bridge plate is provided with a transmission component, and its corner plate is used to contact the transmission component;

[0010] Furthermore, the monitoring component includes an upper end plate, the top end of the upper end plate is hingedly connected to an axis block, one side of the axis block is rotatably connected to a roller, the other end of the axis block is provided with an extension axis parallel to the axis block, the extension axis is connected to a lap rod, the lap rod is rotatably connected to an arc rod, the arc rod penetrates into the interior of the upper end plate, the roller is close to the rear of the fuse tube, and a contact sensor is installed on one side of the upper end plate.

[0011] Furthermore, the center of the arc rod is concentric with the rotation center axis of the shaft block. When the roller is squeezed by the fuse tube and drives the shaft block to rotate, the arc rod can move along a stable arc path. This smooth transmission mechanism reduces the friction, vibration and wear that may be caused by non-concentric rotation, thereby improving the stability and durability of the system.

[0012] Furthermore, extension blocks are provided on both sides of the upper end plate. The extension blocks can limit the rotation position of the shaft block, that is, the extension blocks make the initial position of the shaft block horizontally fit on the surface of the extension blocks, and when the arc rod slides toward the inside of the upper end plate, the maximum rotation position of the extension shaft will also be blocked by the extension blocks, thereby limiting the maximum rotation angle of the shaft block.

[0013] Furthermore, the two ends of the screw have thread structures, and the middle part thereof has no thread structure, and the two ends of the screw are threadedly engaged with collars. The collars are rotatably installed from the two ends of the screw, and the connecting rod is placed between the two collars. The two collars limit the installation position of the connecting rod. Since the middle part of the screw has no thread structure, the connecting rod can be easily rotated freely in the middle part of the screw.

[0014] Furthermore, a slide groove is surrounded by the outer side of the ring, a mounting groove is provided at one end of the slide groove, a slider is slidably installed inside the slide groove, and limiting ears are provided at both ends of the slider, wherein the shape formed by the slider and the limiting ears matches the inside of the slide groove, a filling block is installed inside the mounting groove, a countersunk groove is provided in the filling block, and the countersunk groove passes through one side of the ring, a spring is installed inside the slide groove, an open arc plate is installed on the outer side of the slide groove, and a traction rod is installed on the slider, and the traction rod is close to the connecting rod side.

[0015] Furthermore, the transmission component includes a signal generator, a built-in slot is provided inside the signal generator, a pressure plate is slidably connected inside the built-in slot, compression springs are installed at both ends of the pressure plate, and an induction contact is provided at the top of the built-in slot.

[0016] Furthermore, a connecting head is provided on the top of the first rotating plate, a connecting ear is installed on the surface of the bracket, a coupling plate is installed on the connecting ear, a coupling rod is hingedly installed above the coupling plate, and the other end of the coupling rod is hingedly connected to the connecting head.

[0017] Furthermore, the signal generator and the contact sensor use wireless communication technology, which is a mobile communication network or satellite communication.

[0018] The technical solution of the present invention has the following beneficial effects:

[0019] 1. If the fuse tube falls, it will contact the extrusion roller, and the shaft block will deflect slightly along the top of the upper end plate, that is, the arc rod will pass through the inside of the upper end plate, so that the tail end of the arc rod will contact the surface of the contact sensor, thereby giving an early warning to indicate that the fuse tube has fallen. The stability of the mechanical structure ensures the reliability of the system in long-term use and has high adaptability.

[0020] 2. The fuse tube falls and hits the roller. The roller transfers the force to the connecting rod and pushes the connecting rod to rotate around the screw. When the connecting rod rotates, the corner plate at its bottom will contact the bottom of the signal generator, so that the connecting rod contacts the surface of the pressure plate, generating pressure to cause the compression spring to contract. The pressure plate will contact the induction contact, and the signal generator will generate a signal, so that the remote monitoring center can monitor whether the fuse tube falls in real time. After the fuse tube falls, the remote monitoring center will issue an alarm to urge the maintenance personnel.

[0021] 3. Adjust the installation angle of the coupling plate, so as to adjust the installation angle position of the first rotating plate, so as to adjust the position of the monitoring component as a whole, change the contact position of the roller on the fuse tube, adjust the coupling plate to a suitable position and install it on the connecting ear by bolts, tighten the bolts to stabilize the coupling plate, and improve the adjustability and flexibility of the overall equipment.

[0041] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] refer to Figure 1-Figure 13 , an intelligent monitoring device for a drop-out fuse, comprising an insulator 10, a buckle head 11 being provided at the upper end of the insulator 10, a fuse tube 101 being installed at the bottom of the insulator 10, an operating ring 102 being provided on the fuse tube 101, a bracket 12 being installed at the bottom end of the insulator 10, and a first rotating plate 13 and a second rotating plate 133 being installed at hinges on both sides of the bracket 12;

[0044] In the above solution, the snap-fit ​​head 11 is the contact of the fuse tube 101 of the drop-out fuse, and the staff pushes the fuse tube 101 to snap into the snap-fit ​​head 11 by operating the ring 102 .

[0045] refer to Figure 1-Figure 7 A mounting end 132 is provided on one side of the first rotating plate 13, and a screw 15 is connected to the mounting end 132 and the second rotating plate 133. A connecting rod 14 is rotatably mounted on the screw 15, and a monitoring component is provided above the connecting rod 14, and the monitoring component is supported behind the fuse tube 101. An axial hole 141 is provided on the connecting rod 14, and the axial hole 141 is sleeved on the screw 15;

[0046] In the above solution, the screw 15 combines the first rotating plate 13 and the second rotating plate 133. Under the action of the screw 15, the rotation of the first rotating plate 13 will simultaneously drive the rotation of the second rotating plate 133. Since the monitoring component is supported at the rear of the fuse tube 101, when the fuse tube 101 falls, the rear of the fuse tube 101 will be squeezed on the monitoring component, that is, the connecting rod 14 will be deflected at an angle.

[0047] refer to Figure 3-Figure 7 The monitoring component includes an upper end plate 142, the top end of the upper end plate 142 is hingedly connected to an axis block 143, one side of the axis block 143 is rotatably connected to a roller 144, the other end of the axis block 143 is provided with an extension axis 145 parallel to the axis block 143, the extension axis 145 is connected to a lap rod 146, the lap rod 146 is rotatably connected to an arc rod 147, the arc rod 147 penetrates into the interior of the upper end plate 142, the roller 144 is close to the rear of the fuse tube 101, and a contact sensor 149 is installed on one side of the upper end plate 142.

[0048] In the above solution, the fuse tube 101 falls down. Figure 1In the monitoring system, the fuse tube 101 will contact the extrusion roller 144, and the shaft block 143 will deflect slightly along the top of the upper end plate 142, that is, the arc rod 147 will pass through the interior of the upper end plate 142, so that the tail end of the arc rod 147 contacts the surface of the contact sensor 149, thereby giving an early warning to prompt in advance that the fuse tube 101 has fallen. The direct contact between the roller 144 and the fuse tube and the micro-deflection mechanism of the shaft block 143 make the monitoring system extremely sensitive to the fall of the fuse tube 101. At the same time, the stability of the mechanical structure ensures the reliability of the system in long-term use and has high adaptability. Through timely early warning, the operator can take measures to intervene before the fuse tube 101 falls completely and may cause greater losses. This not only helps to reduce the risk of equipment damage, but also protects the safety of on-site personnel and reduces maintenance and replacement costs. Its contact sensor 149 uses wireless communication technology such as mobile communication networks or satellite communications to ensure real-time transmission and accuracy of data.

[0049] It is worth noting that a torsion spring is built into the top hinge connection portion between the shaft block 143 and the upper end plate 142 , and the function of the torsion spring is to automatically reset the shaft block 143 to its initial position.

[0050] Further references Figure 7 , the center of the arc rod 147 is concentric with the rotation center axis of the shaft block 143. Since the center of the arc rod 147 is concentric with the rotation center axis of the shaft block 143, when the roller 144 is squeezed by the fuse tube 101 and drives the shaft block 143 to rotate, the arc rod 147 can move along a stable arc path. This smooth transmission mechanism reduces the friction, vibration and wear that may be caused by non-concentric rotation, thereby improving the stability and durability of the system. The concentric design ensures the accuracy of the arc rod 147 during movement. When the fuse tube 101 falls and triggers the roller 144, the arc rod 147 can move according to the predetermined path and distance until its tail end accurately contacts the contact sensor 149. This precise displacement control improves the accuracy of the warning signal and reduces the possibility of false alarms or missed alarms.

[0051] Further references Figure 5 and Figure 7 , extension blocks 148 are provided on both sides of the upper end plate 142. The extension blocks 148 can limit the rotation position of the shaft block 143, that is, the extension blocks 148 make the initial position of the shaft block 143 horizontally attached to the surface of the extension blocks 148, when the arc rod 147 slides inside the upper end plate 142, that is, the maximum rotation position of the extension shaft 145 will also be blocked by the extension blocks 148, thereby limiting the maximum rotation angle of the shaft block 143.

[0052] Further references Figure 5 and Fig.11The screw rod 15 has a thread structure at both ends, and there is no thread structure in the middle part. The two ends of the screw rod 15 are threadedly engaged with collars 16. The collars are rotated and installed from both ends of the screw rod 15, and the connecting rod 14 is placed between the two collars 16. The two collars 16 limit the installation position of the connecting rod 14. Since there is no thread structure in the middle part of the screw rod 15, the connecting rod 14 can be easily rotated freely in the middle part of the screw rod 15.

[0053] Furthermore, a slide groove 161 is surrounded on the outside of the collar 16, and a mounting groove 162 is provided at one end of the slide groove 161. A slider 163 is slidably installed inside the slide groove 161, and limiting ears 164 are provided at both ends of the slider 163, wherein the shape formed by the slider 163 and the limiting ears 164 matches the inside of the slide groove 161, and a filling block 165 is installed inside the mounting groove 162, and a countersunk groove 166 is provided in the filling block 165, and the countersunk groove 166 passes through one side of the collar 16, a spring 168 is installed inside the slide groove 161, and an open arc plate 167 is installed on the outside of the slide groove 161, and a traction rod 169 is installed on the slider 163, and the traction rod 169 is close to the side of the connecting rod 14.

[0054] In the above scheme, the assembly method of the slider 163 is as follows: first, remove the filling block 165 from the installation groove 162, and put the slider 163 into the installation groove 162, then make the slider 163 and the limiting ear 164 cooperate with the inside of the slide groove 161, and then put the spring 168 into the slide groove 161. The spring 168 is an arc-shaped structure that fits inside the slide groove 161, and then install the open arc plate 167 to fit the outer wall of the slide groove 161. The purpose of the open arc plate 167 is to stabilize the spring 168 inside the slide groove 161 to prevent it from escaping from the inside of the slide groove 161; then install the filling block 165 in the installation groove 162 to limit the slider 163 from escaping from the inside of the slide groove 161, and finally install the bolt in the counterbore groove 166. The bolt is tightened to contact the outer wall of the screw rod 15, thereby limiting the rotation of the collar 16 on the screw rod 15, so as to prevent the collar 16 from rotating due to the sliding force of the slider 163, thereby changing the installation position of the collar 16;

[0055] The use process of the slider 163: When the fuse tube 101 falls, it will hit the roller 144, and the roller 144 will transfer the force to the connecting rod 14, and at the same time, it will push the connecting rod 14 to rotate around the screw 15. The rotation of the connecting rod 14 will contact the traction rod 169, that is, the slider 163 rotates around the slide groove 161, and the displacement of the slider 163 causes the spring 168 to deform; when the fuse tube 101 returns to the engaging head 11, the slider 163 is reset under the thrust of the spring 168, that is, the connecting rod 14 returns to the initial position.

[0056] Embodiment 2:

[0057] refer to Fig.12 and Fig.13 A corner plate 140 is provided below the connecting rod 14, a tail plate 134 is provided at the bottom end of the first rotating plate 13, a bridge plate 17 is installed on the side of the tail plate 134, and side ears 171 are provided at both ends of the bridge plate 17, wherein the side ears 171 are installed on the tail plate 134 and the second rotating plate 133, and a transmission component is provided on the bridge plate 17, and its corner plate 140 is used to contact the transmission component. The transmission component includes a signal generator 172, a built-in groove 173 is provided inside the signal generator 172, a pressure plate 174 is slidably connected inside the built-in groove 173, compression springs 175 are installed at both ends of the pressure plate 174, and a sensing contact 176 is provided at the top of the built-in groove 173.

[0058] In the above scheme, the fuse tube 101 falls and hits the roller 144. The roller 144 transmits the force to the connecting rod 14, and at the same time pushes the connecting rod 14 to rotate around the screw 15. When the connecting rod 14 rotates, the corner plate 140 at its bottom will contact the bottom of the signal generator 172, so that the connecting rod 14 contacts the surface of the pressure plate 174, and the pressure generated causes the compression spring 175 to contract. The pressure plate 174 will contact the induction contact 176, and the signal generator 172 generates a signal. Through the ADC (analog-to-digital converter), the analog signal can be converted into a digital signal, and the data can be transmitted to the computer through the USB, 10 Gigabit network and other interfaces, and the computer can be used to determine which fuse tube 101 has fallen. Or, the signal is received through a 4G or 5G communication module, and the data signal is fed back to the computer, so that the remote monitoring center can monitor in real time whether the fuse tube has fallen. After the fuse tube falls, the remote monitoring center will issue an alarm to urge the maintenance personnel, so that the maintenance personnel can repair or replace the fallen fuse tube in time. Or, mobile communication network or satellite communication can be used.

[0059] In this embodiment, a signal generator 172 is additionally added to the contact sensor 149 of the first embodiment to improve the data feedback of the signal.

[0060] Embodiment three:

[0061] refer to Figure 4 A connecting head 131 is provided on the top of the first rotating plate 13, a connecting ear 121 is installed on the surface of the bracket 12, a coupling plate 18 is installed on the connecting ear 121, a connecting rod 181 is hingedly installed above the coupling plate 18, and the other end of the connecting rod 181 is hingedly connected to the connecting head 131.

[0062] In the above scheme, by adjusting the installation angle of the coupling plate 18, the installation angle position of the first rotating plate 13 is adjusted, so as to adjust the position of the monitoring component as a whole, change the contact position of the roller 144 on the fuse tube 101, and adjust the coupling plate 18 to a suitable position and install it on the connecting ear 121 by bolts. Tighten the bolts to stabilize the coupling plate 18, thereby improving the adjustability and flexibility of the overall equipment.

[0063] The specific implementation process of the above embodiment is as follows:

[0064] The fuse tube 101 falls down. Figure 1 In the process, the fuse tube 101 will contact the extrusion roller 144, and the shaft block 143 will deflect slightly along the top of the upper end plate 142, that is, the arc rod 147 will pass through the interior of the upper end plate 142, so that the tail end of the arc rod 147 will contact the surface of the contact sensor 149, thereby issuing an early warning to prompt the fuse tube 101 to fall in advance.

[0065] When the fuse tube 101 falls, it will hit the roller 144, and the roller 144 will transfer the force to the connecting rod 14, and at the same time, it will push the connecting rod 14 to rotate around the screw 15. The rotation of the connecting rod 14 will contact the traction rod 169, that is, the slider 163 rotates around the slide groove 161, and the displacement of the slider 163 causes the spring 168 to deform. When the connecting rod 14 rotates, the corner plate 140 at the bottom will contact the bottom of the signal generator 172, so that the connecting rod 14 contacts the surface of the pressure plate 174, and the pressure generated causes the compression spring 175 to contract. The pressure plate 174 will contact the induction contact 176, and the signal generator 172 generates a signal. Through the ADC (analog-to-digital converter), the analog signal can be converted into a digital signal, and the data can be transmitted to the computer through the USB, 10G network and other interfaces. Or the signal is received through the 4G or 5G communication module, and the data signal is fed back to the computer. When the fuse tube 101 returns to the engaging head 11, the slider 163 is reset under the thrust of the spring 168, that is, the connecting rod 14 returns to the initial position.
