Description

Technical Field

[0001] This invention relates to the field of electrical safety monitoring devices, and in particular to a portable electrical safety monitoring device and monitoring method. Background Technology

[0002] In the power sector, electricity meters are key devices for accurately measuring electricity consumption and monitoring power parameters. Their reliability directly affects the stable operation of the power system and the fairness of electricity transactions. Therefore, regular and accurate testing of electricity meters is a necessary step to ensure the quality of power supply. Traditionally, technicians mainly use multimeters to test electricity meters. By connecting the multimeter's probes to the meter's contacts, they obtain various electrical parameters of the meter to determine whether it is working properly.

[0003] A digital multimeter with anti-misoperation function, disclosed in patent application CN119104765A, includes a housing. The housing has a hollow interior structure. An anti-slip patch is fixedly connected to one side of the housing. A threaded post is fixedly connected to the bottom of the inner wall of the housing. A circuit module is fixedly connected to the top of the threaded post. A first pin header and a second pin header are fixedly connected to the top of the circuit module. A heater is fixedly connected to one side of the inner wall of the housing. An electromagnetic circuit breaker is fixedly connected to the top of the circuit module. The electromagnetic circuit breaker includes a rear contact plate. The bottom of the rear contact plate is fixedly connected to the first pin header. A sliding tube is fixedly connected to the back of the rear contact plate. Test leads are inserted into the back of the housing. This multimeter reduces the possibility of slippage in low-temperature and humid environments, reduces the risk of short circuits or accidental touches caused by water contact with the circuit module, and improves the reliability and safety of the device.

[0004] Traditional monitoring equipment has significant shortcomings in probe cleaning, rapid risk avoidance, and modular maintenance. Specifically, long-term exposure of probes can lead to the accumulation of oxide layers and dust, resulting in a decrease in resistance measurement accuracy; the lack of an automatic retraction mechanism in emergencies poses a risk of equipment damage and electric shock to personnel; and the integrated design means that partial failures require replacement of the entire unit, resulting in high maintenance costs.

[0005] Therefore, it is necessary to provide a portable electrical safety monitoring device and method to solve the above-mentioned technical problems. Summary of the Invention

[0013] As a further aspect of the present invention, it also includes a disconnection mechanism, which comprises a rotating ring rotatably connected to one end of a movable column, and a push rod fixedly connected to the outer side of the rotating ring, extending to the outer side of the locking block. A fixed plate is fixedly connected to the outer side of the movable column, and a connecting plate is fixedly connected to the inner side of the rotating ring. An elastic element is fixedly connected between the connecting plate and the fixed plate. When the elastic element is in a compressed state, a heat-conducting ring is sleeved on the outer side of the probe, and the heat-conducting ring is fixedly connected to the movable column. A memory metal plate is fixedly connected to the outer side of the heat-conducting ring, and a wire is fixedly connected between the memory metal plate and the connecting plate. When the memory metal plate is heated and deformed, the elastic element pushes the connecting plate to move. At this time, the rotating ring pushes the locking block to slide out of the locking plate through the push rod.

[0014] As a further aspect of the present invention: multiple mounting cylinders are fixedly connected to the outside of the plug-in cylinder, a movable plate is provided inside the mounting cylinder, a fourth airbag is fixedly connected between one side of the movable plate and the mounting cylinder, a first air supply pipe is provided between the fourth airbag and the second airbag, a fifth airbag is fixedly connected between the other side of the movable plate and the mounting cylinder, a second air supply pipe is fixedly connected between the fifth airbag and the third airbag, an annular plate is sleeved on the outside of the plug-in cylinder, multiple pull rods are fixedly connected to the outside of the annular plate, the pull rods are fixedly connected to the annular plate, multiple fifth springs are fixedly connected between the annular plate and the movable column, and a pull rope is fixedly connected between the annular plate and the push rod.

[0015] As a further aspect of the present invention: multiple limiting plates are provided on the outer side of the plug-in tube, the limiting plates extend into the interior of the plug-in tube and are slidably connected to the plug-in tube, a sliding shaft is fixedly connected to the outer side of the limiting plates, a fixed support plate is fixedly connected to the outer side of the plug-in tube, a sixth spring is fixedly connected between the fixed support plate and the limiting plates, a pushing frame is provided on the outer side of the limiting plates, the pushing frame is slidably connected to the outer side of the plug-in tube, and a guide groove is provided on the outer side of the pushing frame, a return spring is fixedly connected between the pushing frame and the plug-in tube, and a traction rope is fixedly connected between the pushing frame and the moving plate.

[0016] A portable method for monitoring electrical safety includes the following steps: Step 1: Insert one end of the connector into the pin on the multimeter; Step 2: When in use, press the unlocking piece on the fixed frame and push the fixed frame to make the probe at one end of the movable column slide out of the storage tube. The probe contacts the detection piece to perform electrical testing. Step 3: After use, press the unlocking part, and the movable column will drive the probe to retract into the storage cylinder. During the retraction process, the inflation part inflates the swing ring, and the swing ring cleans the surface of the guide rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The probe is stored in a storage tube, and a swing ring is used to process the probe as it is stored inside the storage tube, ensuring that the probe is clean before each use. The swing ring driven by the inflation component can remove contaminants from the guide rod surface when the probe retracts, ensuring that the probe contact surface is clean before each test and avoiding resistance measurement errors caused by oxide layer or dust.

[0018] 2. The swing ring reciprocates inside the wave groove via the guide shaft on the outside of the swing ring. During the swinging process, the swing ring drives the swing rod to rotate through the sliding plate. The swing rod drives the rotating plate to reciprocate, thereby cleaning the airbag and the probe through frictional contact, thus improving the cleaning effect on the probe.

[0019] 3. When the connecting plate moves, it drives the rotating ring to rotate. When the rotating ring rotates, it drives the fixed connecting push rod to push the locking block, causing the locking block to slide out of the locking plate. At this time, the guide rod quickly pulls the movable column to move. The movable column drives the probe to retract, thereby moving away from the detection position. It automatically retracts without being noticed by personnel, thus protecting the equipment and personnel.

[0020] 4. The second airbag contracts, thus disengaging the conductive sheet from the connector. The moving plate then compresses the fifth airbag, causing the gas inside the fifth airbag to rush into the third airbag. The third airbag then pushes out the connector inside the connector tube, facilitating subsequent disassembly and inspection by personnel. This avoids the need for complete replacement and allows for replacement of only the damaged parts. The conductive sheet separates from the connector, cutting off the circuit.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] like Figures 1 to 11 As shown, a portable electrical safety monitoring device and method include the following embodiments: Based on the above ideas, the present invention provides the following technical solution: Example 1: Includes a multimeter 1 and a connector 2, and also includes: Storage tube 3, one end of storage tube 3 is fixedly connected to plug wire 2, storage tube 3 is provided with movable column 4, one end of movable column 4 is fixedly connected to probe 401, movable column 4 and storage tube 3 are provided with sliding parts, and the other end of movable column 4 and plug wire 2 are provided with docking components. Two snap-fit ​​plates 301 are fixedly connected inside the storage tube 3. A rotating half-ring 501 is rotatably connected to the outside of the movable column 4. A snap-fit ​​block 502 is fixedly connected to the outside of the rotating half-ring 501. A fixed frame 5 is fixedly connected to the outside of the movable column 4. An unlocking component is provided between the fixed frame 5 and the rotating half-ring 501 to push the rotating half-ring 501 to rotate and unlock. A rotating plate 6 is fixedly connected to the end of the storage tube 3 away from the plug-in cable 2. A cleaning airbag 601 is fixedly connected inside the rotating plate 6. An inflation component is provided at the end of the movable column 4 near the plug-in cable 2. When the movable column 4 drives the probe 401 to retract into the storage tube 3, it drives the inflation component to inflate the cleaning airbag 601 and clean the outside of the movable column 4.

[0027] In practical implementation, existing power consumption monitoring often uses a multimeter to test equipment or lines. During testing, a protective sleeve is usually placed over the probe 401, which needs to be removed before use. However, the probe 401 remains exposed throughout use, making it susceptible to damage or injury. Therefore, in this solution, one end of the connector 2 is inserted into the hole on the multimeter 1. When in use, pressing the unlocking mechanism on the fixing frame 5 and pushing the fixing frame 5 causes the probe 401 at one end of the movable column 4 to slide out of the storage cylinder 3, allowing it to contact the testing component for power consumption testing. After use, press the unlocking mechanism. The movable column 4 drives the probe 401 to retract into the storage cylinder 3. During the retraction process, the inflation component inflates the swing ring 602, which cleans the surface of the guide rod 402. The probe 401 is then stored in the storage cylinder 3. At the same time, the swing ring 602 processes the probe when it is stored in the storage cylinder 3, ensuring that the probe 401 is clean each time it is used. The swing ring 602 driven by the inflation component can remove contaminants from the surface of the guide rod 402 when the probe retracts, ensuring that the probe contact surface is clean each time it is tested, and avoiding resistance measurement errors caused by oxide layers or dust.

[0028] Example 2: The sliding component includes a guide rod 402 fixedly connected inside the storage cylinder 3, a sliding seat 404 fixedly connected to the outside of the movable column 4, and a first spring 403 fixedly connected between the sliding seat 404 and the storage cylinder 3 for pulling the movable column 4 to retract into the storage cylinder 3.

[0029] The unlocking component includes a pressing plate 503, which is fixedly connected to the outside of the rotating half-ring 501. A second spring 505 is fixedly connected between the pressing plate 503 and the fixed frame 5. The second spring 505 pushes the pressing plate 503, thereby causing the locking block 502 on the outside of the rotating half-ring 501 to be inserted into the locking block 502. A first sliding groove 504 is provided on the outside of the pressing plate 503. A push shaft 507 is slidably connected inside the first sliding groove 504. A pressing button 506 is fixedly connected to the outside of the push shaft 507. The pressing button 506 passes through the top of the fixed frame 5 and is slidably connected to the fixed frame 5. A third spring 508 is fixedly connected between the pressing button 506 and the fixed frame 5.

[0030] In practice, when the probe 401 needs to be slid out, the operator can press the squeeze button 506 on the top of the fixed frame 5. The squeeze button 506 pushes the push shaft 507, which slides in the first groove 504 on the outside of the squeeze plate 503. This pushes the squeeze plate 503 to squeeze the second spring 505, causing the squeeze plate 503 to slide the rotating half-ring 501 fixedly connected to the outside of the movable column 4. The locking block 502 fixedly connected to the outside of the rotating half-ring 501 slides out of the locking plate 301, thus engaging the locked state. The operator can then push the fixed frame 5, causing the movable column 4 to move. Once it reaches the designated position, the operator can release the lever, and the second spring 505 will push the squeeze plate 503, causing the locking block 502 to re-insert into the locking plate 301 for locking. When storage is required, the operator can press the squeeze button 506, at which point the first spring 403 will pull the sliding seat 404 on the outside of the movable column 4 to retract and move into the storage cylinder 3.

[0031] Example 3: The inflatable component includes a rotating ring 600, which is rotatably connected to one end of the movable column 4. A swing ring 602 is provided on one side of the rotating ring 600. A first telescopic rod 604 and a fourth spring 605 are fixedly connected between the swing ring 602 and the rotating ring 600. The fourth spring 605 is sleeved on the outside of the first telescopic rod 604. A first airbag 603 is fixedly connected between the swing ring 602 and the rotating ring 600. A connecting tube is fixedly connected between the first airbag 603 and the cleaning airbag 601.

[0032] The inflatable component also includes a guide plate 607, which is fixedly connected to the inside of the storage tube 3. A wave groove is provided on the outer side of the guide plate 607. A guide shaft 606 is fixedly connected to the outer side of the swing ring 602. The guide shaft 606 extends into the wave groove of the guide plate 607 and is slidably connected to the guide plate 607. A sliding plate 609 is fixedly connected to the outer side of the swing ring 602. A swing rod 608 is fixedly connected to the outer side of the rotating plate 6. The sliding plate 609 is sleeved on the outer side of the swing rod 608 and is slidably connected to the swing rod 608.

[0033] In practice, when the guide rod 402 is retracted into the storage cylinder 3 after each use, it is cleaned by the cleaning airbag 601 on the rotating plate 6 as it passes the rotating plate 6. The cleaning airbag 601 is a hollow frustum shape, with the larger radius end away from the movable column 4. When the movable column 4 moves into the storage cylinder 3, it pushes the swing ring 602 to move together via the first telescopic rod 604 and the fourth spring 605. Since the guide shaft 606 fixedly connected to the outside of the swing ring 602 extends into the wave groove on the outside of the guide plate 607, the guide plate 607 will block the swing ring 602. Therefore, the rotating ring 600 will squeeze the first airbag 603 on the swing ring 602. At this time, the gas inside the first airbag 603 rushes into the cleaning airbag 601, causing the cleaning airbag 601 to expand and make full contact with the guide rod 402. After the first airbag 603 is compressed, it continues to push the swing ring 602 to move. When the swing ring 602 moves, it rotates back and forth inside the wave groove via the guide shaft 606 on the outside of the swing ring 602. During the swinging process, the swing ring 602 drives the swing rod 608 to rotate via the sliding plate 609. The swing rod 608 drives the rotating plate 6 to rotate back and forth, thereby making frictional contact between the cleaning airbag 601 and the probe 401, thus improving the cleaning effect on the probe 401. Furthermore, when the probe 401 is pushed out later, the fourth spring 605 and the first telescopic rod 604 between the rotating ring 600 and the swing ring 602 will push the swing ring 602 away from the rotating ring 600, and the gas inside the cleaning airbag 601 will be re-entered into the first airbag 603. At this time, the cleaning airbag 601 will contract, and when the probe 401 is removed, the cleaning airbag 601 will not contact the probe 401. Storage and cleaning process 1. Triggering Phase When the movable column 4 retracts, it pushes the swing ring 602 to move. The guide shaft 606 is obstructed in the wave groove, forcing the swing ring 602 to rotate relative to the rotating ring 600; 2. Gas transmission stage The first airbag 603 is rotated and squeezed, and gas is injected into the cleaning airbag 601 through the pipe. Clear the airbag inflation to form contact; Axial friction force cleans the surface of probe 401; 3. Dynamic cleaning stage The continuous movement of the swing ring 602 drives the guide shaft 606 to move along the wave groove trajectory; The typical amplitude of the reciprocating rotation of the rotating plate 6 is ±15°, achieved by the transmission through the sliding plate 609 and the swing rod 608. The airbag is cleaned by a periodic rubbing motion to remove any adhering substances. Reset and avoidance mechanisms: Gas backflow The fourth spring 605 pushes the swing ring 602 to move in the opposite direction; The gas from the airbag is returned to the first airbag 603 via a one-way valve; Non-working status When probe 401 extends, the cleaning airbag fully contracts; Rotating plate 6 is reset to its original angle to avoid motion interference.

[0034] Example 4: The docking assembly includes a flexible wire 201, one end of which is fixedly connected to the plug wire 2, and the other end of which is fixedly connected to a plug connector 202. A baffle 203 is fixedly connected to the outside of the plug connector 202. A plug tube 8 is fixedly connected to one end of the movable column 4. Multiple second airbags 802 are fixedly connected inside the plug tube 8. A conductive sheet 801 is fixedly connected to the outside of each of the multiple second airbags 802. When the conductive sheet 801 contacts the plug connector 202, they are electrically connected. A third airbag 803 is fixedly connected to one end of the plug tube 8.

[0035] In specific implementation, the connector 202 at one end of the elastic wire 201 is inserted into the plug tube 8. The connector 202 makes electrical contact with the conductive sheet 801 on the inflated second airbag 802. The electrical connection between the conductive sheet 801 and the probe 401 makes the probe 401, the conductive sheet 801, the connector 202 and the elastic wire 201 form a series connection.

[0036] In this embodiment, a disconnection mechanism is also included. The disconnection mechanism includes a rotating ring 701, which is rotatably connected to one end of the movable column 4. A push rod 707 is fixedly connected to the outside of the rotating ring 701, and the push rod 707 extends to the outside of the locking block 502. A fixing plate 703 is fixedly connected to the outside of the movable column 4, and a connecting plate 702 is fixedly connected to the inside of the rotating ring 701. An elastic element 704 is fixedly connected between the connecting plate 702 and the fixing plate 703. When the elastic element 704 is in a compressed state, a heat-conducting ring 706 is sleeved on the outside of the probe 401, and the heat-conducting ring 706 is fixedly connected to the movable column. A memory metal plate 705 is fixedly connected to the outside of the heat-conducting ring 706. A wire is fixedly connected between the memory metal plate 705 and the connecting plate 702. When the memory metal plate 705 is heated and deformed, the elastic element 704 pushes the connecting plate 702 to move. At this time, the rotating ring 701 pushes the locking block 502 to slide out of the locking plate 301 through the push rod 707.

[0037] In practical implementation, when a short circuit occurs during the detection process, the probe 401 will experience a temperature rise, which could easily cause damage to people and equipment. Therefore, in this solution, a heat-conducting ring 706 is set on the outside of the probe 401. The heat-conducting ring 706 will transmit high temperatures. At this time, the shape memory metal plate 705 on the outside of the heat-conducting ring 706 will deform due to heat. At this time, the elastic element 704, which is fixedly connected between the fixed plate 703 and the connecting plate 702, will be in a compressed state and will quickly push the connecting plate 702 to move. When the connecting plate 702 moves, it will drive the rotating ring 701 to rotate. When the rotating ring 701 rotates, it will drive the fixedly connected push rod 707 to push the locking block 502, causing the locking block 502 to slide out of the locking plate 301. At this time, the guide rod 402 will quickly pull the movable column 4 to move. The movable column 4 will drive the probe 401 to retract, thereby moving it away from the detection position. It will automatically retract without being noticed by personnel, thus protecting the equipment and personnel. During the temperature sensing stage, the high temperature generated when the probe 401 is short-circuited is quickly conducted to the memory metal plate 705 through the heat conduction ring 706. When the temperature exceeds the set threshold such as 80°C, the memory metal undergoes a phase change deformation. During the mechanical transmission stage, the shape memory metal deforms and releases the pre-compression energy of the elastic element 704. The connecting plate 702 is driven by the thrust to rotate the ring 701 and push the rod 707. The lever principle is used to act on the locking block 502 for protection. During the action stage, the locking block 502 disengages from the locking plate 301 and releases the locking guide rod 402. Under the action of the reset force, the movable column 4 and the probe 401 are pulled to fully retract to the safe position within 0.5 seconds.

[0038] In this embodiment, multiple mounting cylinders 9 are fixedly connected to the outside of the plug-in cylinder 8. A movable plate 901 is provided inside the mounting cylinder 9. A fourth airbag 902 is fixedly connected between one side of the movable plate 901 and the mounting cylinder 9. A first air supply pipe is provided between the fourth airbag 902 and the second airbag 802. A fifth airbag 903 is fixedly connected between the other side of the movable plate 901 and the mounting cylinder 9. A second air supply pipe is fixedly connected between the fifth airbag 903 and the third airbag 803. An annular plate 10 is sleeved on the outside of the plug-in cylinder 8. Multiple pull rods 904 are fixedly connected to the outside of the annular plate 10. The pull rods 904 are fixedly connected to the annular plate 10. Multiple fifth springs 101 are fixedly connected between the annular plate 10 and the movable column 4. A pull rope 102 is fixedly connected between the annular plate 10 and the push rod 707. The pull rope 102 is guided by a support plate. When the push rod 707 rotates, the pull rope 102 pulls the annular plate 10 to move towards the movable column 4.

[0039] In specific implementation, in order to further protect the multimeter 1 and the connector 2, when the push rod 707 rotates, the push rod 707 pulls the annular plate 10 to move through the pull rope 102. The annular plate 10 is connected to the pull rod 904, which drives the fixedly connected moving plate 901 to move. The moving plate 901 pulls the fourth airbag 902 to unfold, so that the gas inside the second airbag 802 is drawn into the fourth airbag 902, causing the second airbag 802 to contract and the conductive sheet 801 to disengage from the connector 202. The moving plate 901 also squeezes the fifth airbag 903, so that the gas inside the fifth airbag 903 rushes into the third airbag 803. Then the third airbag 803 pushes out the connector 202 inside the connector cylinder 8, which is convenient for subsequent personnel to disassemble and test, avoiding the need for overall replacement. Replacement can be done according to the specific damaged parts. Protection mechanism triggering process When the push rod 707 rotates clockwise, it transmits the pulling force to the annular plate 10 through the pull rope 102. The annular plate 10 drives the pull rod 904 to move horizontally, causing the moving plate 901 to compress the fourth airbag 902. The negative pressure generated by the contraction of the fourth airbag 902 causes the second airbag 802 to contract synchronously. The conductive sheet 801 separates from the connector 202, cutting off the circuit.

[0040] In this embodiment, multiple limiting plates 112 are provided on the outside of the plug-in tube 8. The limiting plates 112 extend into the inside of the plug-in tube 8 and are slidably connected to the plug-in tube 8. A sliding shaft 114 is fixedly connected to the outside of the limiting plates 112. A fixed support plate 111 is fixedly connected to the outside of the plug-in tube 8. A sixth spring 115 is fixedly connected between the fixed support plate 111 and the limiting plates 112. A push frame 11 is provided on the outside of the limiting plates 112. The push frame 11 is slidably connected to the outside of the plug-in tube 8. A guide groove 113 is opened on the outside of the push frame 11. A reset spring is fixedly connected between the push frame 11 and the plug-in tube 8. A traction rope is fixedly connected between the push frame 11 and the moving plate 901.

[0041] In specific implementation, when the moving plate 901 moves in the above scheme, the traction rope pulls the push frame 11, and the push frame 11 pushes the limit plate 112 up through the guide groove 113, thereby releasing the restriction on the baffle 203 on the outside of the connector 202, making it easier for personnel to remove. When subsequent personnel connect the connector 202 with the connector tube 8, since the limit plate 112 is set as an inclined surface near the outside of the connector 202, the baffle 203 can push the limit plate 112 up. After the limit plate 112 rises, the sixth spring 115 pushes the limit plate 112 down, thereby locking the baffle 203.

[0042] A portable method for monitoring electrical safety includes the following steps: Step 1: Insert one end of connector 2 into the hole marked on multimeter 1; Step 2: When in use, press the unlocking piece on the fixed frame 5 and push the fixed frame 5 to make the probe 401 at one end of the movable column 4 slide out from the storage tube 3, and make contact with the detection piece through the probe 401 to perform live detection. Step 3: After use, press the unlocking part, and the movable column 4 will drive the probe 401 to retract into the storage cylinder 3. During the retraction process, the inflation part inflates the swing ring 602, and the swing ring 602 cleans the surface of the guide rod 402.
