Description

Technical Field

[0001] This invention relates to the field of power protection and control technology, specifically to a general-purpose power protection and control device. Background Technology

[0002] With the advancement of automation and unmanned operation and maintenance in power systems, the traditional fault diagnosis mode relying on manual inspection is no longer sufficient to meet the needs. Manual inspection suffers from problems such as slow response, limited coverage, and difficulties in operation at night and in harsh environments, making it impossible to achieve 24-hour real-time monitoring and rapid handling of line connection points. Therefore, the industry urgently needs power protection and control devices with "real-time monitoring, automatic identification, rapid unlocking, and fault isolation" functions to improve the safety and operation and maintenance efficiency of low-voltage distribution circuits and reduce economic losses and safety risks caused by faults.

[0003] The existing equipment isolation structure is mostly a "fixed compartment" design. The opening direction and internal space of the isolation compartment cannot be adjusted according to the cable specifications and installation location. The fixed opening direction means that faulty cables need to be manually guided into the compartment. If the cable length and direction do not match the isolation compartment, problems such as "clogged cable" or "incomplete containment" are likely to occur, and an effective seal cannot be formed. Summary of the Invention

[0004] The present invention provides a universal power protection and control device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a general power protection and control device, comprising an insulating base, wherein the insulating base is detachably connected to an external wall or plate by fasteners, and is used to provide an installation carrier and insulation protection for the entire device;

[0006] An isolation mechanism, located on the top of the insulating base, is used to physically isolate the circuit where combustion or arc discharge occurs, preventing the fault from spreading.

[0007] A control mechanism, which is mounted on the insulating base corresponding to the isolation mechanism, is used to split the two connected lines and transport the faulty line to the isolation mechanism.

[0008] A locking mechanism, which works in conjunction with the control mechanism, is used to lock and fix the two lines in the docking state, while ensuring the stability of the line connection.

[0009] The isolation mechanism, control mechanism, and locking mechanism work together: by detecting abnormal high temperature and electric arc at the connection point of the line, the control mechanism first releases the locking mechanism from the line, and then controls the opening orientation and position of the isolation mechanism to achieve the separation and isolation of the faulty line;

[0010] The isolation mechanism includes a U-shaped rod, an isolation chamber, and a No. 1 spring. The U-shaped rod is vertically fixedly installed on the top of the insulating base. The isolation chamber is fixedly installed at the end of the U-shaped rod away from the insulating base and is used to accommodate the faulty line. A sleeve is sleeved on the outside of the U-shaped rod. One end of the No. 1 spring is fixedly connected to the sleeve, and the other end is fixedly connected to the outer wall of the isolation chamber.

[0011] The first spring is normally in a torsional compression state to drive the opening of the isolation chamber toward the insulating base, maintaining the initial closed state.

[0012] Preferably, the outer side of the insulating base is provided with a horizontal groove extending in the horizontal direction, a No. 1 plate is slidably adapted in the horizontal groove, a No. 1 connecting strip is fixedly connected to the outer side of the No. 1 plate, and the end of the No. 1 connecting strip away from the No. 1 plate is fixedly connected to the outer wall of the isolation chamber.

[0013] When the control mechanism triggers the isolation action, the first plate slides along the transverse groove to one end away from the initial position, and drives the isolation chamber to deflect around the U-shaped rod as the center of rotation through the first connecting bar, so that the opening of the isolation chamber turns towards the control mechanism.

[0014] Preferably, the control mechanism includes a fourth plate, a transverse rail, an electric push rod, and a first rod; the fourth plate is vertically fixedly installed on the outside of the insulating base to support the control mechanism; the transverse rail is fixedly installed on the outside of the fourth plate in a horizontal direction; the electric push rod is fixedly installed at one end inside the transverse rail; the outside of the first rod is fixedly connected to the output end of the electric push rod, and the first rod is slidably adapted to the inner wall of the transverse rail.

[0015] The electric push rod drives the first rod to slide along the transverse rail, thereby realizing the splitting of the circuit and the output of power.

[0016] Preferably, the control mechanism further includes a first telescopic rod, a second plate, and a second spring; the first telescopic rod is vertically fixedly installed on the top of the insulating base with its telescopic end facing downwards; the second plate is horizontally fixedly installed at the bottom of the telescopic end of the first telescopic rod; the second spring is coaxially sleeved on the outside of the first telescopic rod, with its top end fixedly connected to the top of the inner cavity of the insulating base and its bottom end fixedly connected to the top of the second plate.

[0017] The second spring is normally in a torsional compression state, so as to maintain the second plate with downward preload through elastic force, ensuring the stability of the circuit connection.

[0018] Preferably, the control mechanism further includes an insert, a second connecting strip, a solder sheet, a tapered roller bearing, a third plate, a second rod, and a third rod; the insert is correspondingly inserted into the outer end face of the second plate to provide driving force to the first plate; one end of the second connecting strip is fixedly connected to the outer side of the second plate, and the other end is welded to the solder sheet, which is used to realize the disconnection processing of the second connecting strip;

[0019] The inner ring of the tapered roller bearing is pressed and fitted to the bottom of the second plate, and the third plate is horizontally fixedly installed on the bottom of the outer ring of the tapered roller bearing; the second rod and the third rod are respectively vertically fixedly installed on both sides of the end of the third plate away from the tapered roller bearing, for triggering the unlocking action of the locking mechanism.

[0020] Preferably, the control mechanism further includes a temperature sensor, a vision sensor, and external wiring; the temperature sensor and the vision sensor are respectively fixedly installed on the outside of the fourth board, and the detection ends of both face the wiring connection part; the temperature sensor is used to detect the temperature of the wiring connection part in real time, and the vision sensor is used to monitor whether an arc discharge occurs at the wiring connection part in real time.

[0021] The external circuit is located on the outside of the fourth board, and its top end is fixedly connected to the solder sheet.

[0022] Preferably, the locking mechanism includes a fixing sleeve, a first magnetic block, an insert, and a second magnetic block; the fixing sleeve is fixedly installed on the outside of the fourth plate, and its interior is hollow and fits snugly with the outer wall of the external circuit to wrap and fix the external circuit; the top of the fixing sleeve is fixedly connected to the solder sheet.

[0023] The inner wall of the fixed sleeve has a radially extending groove. The first magnetic block is fixedly installed at the end of the groove away from the groove opening. The insert slides along the length of the groove and adapts to the groove. One end of the insert is fixedly connected to the outer wall of the external line, and the other end extends into the interior of the groove. The second magnetic block is fixedly installed at the end of the insert close to the first magnetic block. The magnetic poles of the second magnetic block and the first magnetic block are the same, and a repulsive force is formed between them to provide an unlocking pre-tightening force for the insert.

[0024] Preferably, the locking mechanism further includes a first elastic telescopic rod and a trapezoidal plate; the first elastic telescopic rod is vertically fixedly installed at the top and bottom of the insert, with its telescopic end facing outward; the trapezoidal plate is fixedly installed at the top of the telescopic end of the first elastic telescopic rod, with its outer side wall pressed against the inner wall of the groove, and the top of the inclined surface of the trapezoidal plate pressed against the bottom of the second rod.

[0025] Preferably, the locking mechanism further includes a second telescopic rod, a limiting plate, a third spring, a curved head, and an extension piece; both sides of the insert are provided with radially extending mounting grooves, the second telescopic rod is fixedly installed in the mounting groove, and its telescopic end faces the mounting groove opening; the limiting plate is slidably adapted to the mounting groove and is fixedly connected to the outer side of the telescopic end of the second telescopic rod; the third spring is sleeved on the outer side of the second telescopic rod, one end of which is fixedly connected to the outer side of the limiting plate, and the other end is fixedly connected to the inner wall of the mounting groove;

[0026] The curved head is fixedly installed at the telescopic end of the second telescopic rod to enhance the fit with the fixed structure; one end of the extension piece is fixedly connected to the outside of the curved head, and the other end extends upward, with its top end pressed against the bottom of the third rod. The extension piece slides within the mounting groove; by pressing the extension piece against the third rod, the curved head is driven to reverse, releasing the auxiliary locking of the insert.

[0027] Preferably, a gear is rotatably mounted on the center of the insert via a shaft, and racks mesh on both sides of the gear. The end of the rack away from the gear is fixedly connected to the trapezoidal plate. Through the meshing transmission of the gear and rack, the trapezoidal plate can be raised and lowered smoothly, ensuring the synchronicity of the unlocking action.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. In the normal locking phase, the combined design of dual mechanical locking and magnetic block pre-tightening significantly improves the reliability of the circuit connection. The curved head and trapezoidal plate form a dual self-locking mechanism through elastic element reset, combined with the repulsive pre-tightening force of the same-pole magnetic blocks. Compared with a single locking structure, the vibration resistance and tensile strength are greatly improved, making it stable and adaptable to vibration environments such as industrial workshops, and fundamentally preventing power instability caused by loose circuit connections. At the same time, a 24-hour monitoring closed loop composed of temperature sensors and vision sensors accurately focuses on the circuit connection points. It not only detects overheating risks through temperature thresholds (70℃±5℃) but also monitors arc discharge through image recognition, effectively overcoming the limitations of traditional single monitoring and providing comprehensive data support for fault early warning.

[0030] 2. The unlocking process after a fault trigger offers the dual advantages of high efficiency and reliability. The thermal triggering design of the solder sheet enables automatic "fault-unlocking" association with a response time of ≤0.3 seconds, far faster than manual unlocking. It is fully adaptable to unattended scenarios, and the solder sheet is low-cost and easy to replace, reducing subsequent maintenance difficulty. In addition, the meshing transmission of gears and racks ensures that the trapezoidal plates retract synchronously, avoiding jamming problems caused by uneven unlocking on one side; the tapered roller bearing allows the No. 3 plate to rotate slightly as the No. 2 plate moves down, ensuring that the unlocking rod is accurately aligned with the trigger point, completely eliminating the jamming risk of traditional mechanical unlocking.

[0031] 3. The circuit splitting and isolation process balances operational precision with safety. The electric push rod and the transverse rail can adaptively adjust the splitting distance according to the circuit specifications, avoiding excessive pulling and damage to the circuit, while the guiding effect of the transverse rail ensures precise pushing position, guaranteeing stable and controllable circuit splitting. The deflection and storage design of the isolation compartment not only saves space compared to a fixed structure, but its flame-retardant and arc-resistant inner wall can also completely seal off the faulty circuit, effectively blocking the spread of flames and arcs, cutting off the fault propagation path spatially, significantly reducing the probability of secondary accidents, and providing key protection for the safety of the power distribution system.

[0048] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1 to 11 The present invention provides a technical solution:

[0050] Example 1: Deployment of Line Locking and Monitoring under Normal Conditions.

[0051] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the external line 304 is inserted into the fixing sleeve 41 of the locking mechanism 4. The fixing sleeve 41 is initially positioned by fitting the external line 304 with its inner wall. The fixing sleeve 41 is fixedly installed on the outside of the fourth plate 305, and its top is fixedly connected to the solder sheet 301. The solder sheet 301 is then welded to the second connecting strip 39 in the control mechanism 3, forming a structural linkage. The insert 44, which moves with the external line 304, extends into the groove 42 on the inner wall of the fixing sleeve 41. One end of the insert 44 is fixedly connected to the outer wall of the external line 304, and the other end extends into the groove 42 and is equipped with a second magnetic block 45. The first magnetic block 43, which is fixedly connected to the end of the groove 42 away from the groove opening, generates a repulsive force with the same pole, storing the unlocking pre-tightening force.

[0052] During the process of inserting the strip 44 into the groove 42, the curved heads 401 on both sides of the strip 44 are squeezed by the groove 42, compressing the second telescopic rod 48 and the third spring 40. The second telescopic rod 48 is fixed in the mounting groove on both sides of the strip 44, and a limit plate 49 is fixed on the outside of the telescopic end. The function of the limit plate 49 is to prevent the curved head 401 from shifting during the contraction process. The third spring 40 is sleeved on the outside of the second telescopic rod 48 and its two ends are fixed to the limit plate 49 and the inner wall of the mounting groove, respectively. When the strip 44 is fully inserted into the groove 42, the third spring 40 returns to its original position and pushes the curved head 401 into the groove of the inner wall of the groove 42. At the same time, the first elastic telescopic rod 46 at the top and bottom of the strip 44 extends, causing the trapezoidal plate 47 to be squeezed against the inner wall of the groove 42, forming a double mechanical lock.

[0053] One end of the curved head 401 is curved, while the other end is right-angled. As the insert 44, carrying the curved head 401, extends into the groove 42, the curved end of the head 401 presses against the inner wall of the groove 42, causing it to compress the second telescopic rod 48 and the third spring 40, and retract into the mounting groove. When the insert 44 is fully inserted into the groove 42, the curved head 401 extends outward again under the elastic force of the third spring 40, with its right-angled end pressing against the inner wall of the groove 42, forming a self-locking state. Additionally, when the insert 44 extends into the groove 42, the inclined portion at the top of the trapezoidal plate 47 presses against the groove 42, compressing the first elastic telescopic rod 46. When the insert 44 is fully inserted into the groove 42, the trapezoidal plate 47 extends outward again and forms a self-locking state with the groove 42.

[0054] The dual mechanical locking combined with the magnetic block pre-tightening design improves vibration and tensile strength by 60% compared to a single locking structure, making it suitable for vibration environments in industrial workshops and preventing loosening of wiring connections. At the same time, the magnetic block repulsive force provides reserve power for unlocking, eliminating the need for additional large thrust for subsequent unlocking and reducing energy consumption.

[0055] Meanwhile, the second spring 36 of the control mechanism 3 is normally in a torsional compression state and is in a balanced state with the second connecting strip 39. This is because the bottom of the second connecting strip 39 is connected to the external circuit 304 and the fixed sleeve 41 respectively through the solder sheet 301. At the same time, the other end of the second connecting strip 39 is connected to the second plate 35, and the bottom end of the second spring 36 is connected to the top of the second plate 35. Therefore, when the second spring 36 wants to cause the second plate 35 to rotate, the second connecting strip 39 will restrict the movement of the second plate 35.

[0056] The temperature sensor 302 and vision sensor 303 on the outside of component 305 are activated, with both detection ends facing the wiring connection point: the temperature sensor 302 collects the temperature of the connection point in real time, and sets the threshold to 70℃±5℃; the vision sensor 303 monitors whether an arc discharge occurs through image recognition, and the detection data is transmitted to the embedded control unit in real time to build a 24-hour monitoring closed loop.

[0057] Example 2: Fault Triggering and Unlocking Process.

[0058] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, when abnormally high temperatures are generated at the connection point of the circuit due to poor contact, i.e., the temperature sensor 302 detects a value exceeding 75°C, or the visual sensor 303 detects an arc discharge, the control unit immediately determines the circuit fault, outputs a drive signal, and quickly shuts off the power supply; the high temperature is conducted to the solder sheet 301, and the solder sheet 301 melts, causing the bottom end of the second connecting strip 39 to be suspended in the air. One end of the second connecting strip 39 is fixed to the outside of the second plate 35, and the other end is welded to the solder sheet 301. After the connection is broken, the second spring 36 releases energy, pushing the second plate 35 to rotate and move downward. Through the tapered roller bearing 38, the third plate 30 is driven to move downward synchronously, so that the second rod 306 and the third rod 307 fixed on both sides of the third plate 30 are aligned with the trapezoidal plate 47 and the extension piece 402, respectively.

[0059] The thermal triggering design of the 301 solder sheet enables automatic "fault-unlock" linkage without manual intervention, with a response time of ≤0.3 seconds, far faster than the 5-10 minutes required for manual unlocking. Furthermore, the 301 solder sheet is low-cost, easy to replace, and facilitates convenient device reset.

[0060] The second rod 306 presses against the inclined surface of the trapezoidal plate 47, forcing the trapezoidal plate 47 to contract and compress the first elastic telescopic rod 46. The trapezoidal plate 47 and the telescopic end of the first elastic telescopic rod 46 are fixedly connected, and the gear 403 in the center of the insert 44 meshes with the racks 404 on both sides for transmission. In addition, the end of the rack 404 away from the gear 403 is fixed to the trapezoidal plate 47 to ensure that the trapezoidal plates 47 on both sides contract synchronously, avoid unilateral unlocking and jamming, and release the compression lock.

[0061] The third rod 307 compresses the extension piece 402. One end of the extension piece 402 is fixed to the outside of the curved head 401, and the other end extends upward and its top is compressed and adapted to the third rod 307. After being compressed, it causes the curved head 401 to flip, so that the curved part and the right angle part of the curved head 401 are interchanged. At this time, the curved part of the curved head 401 will be compressed and adapted to the inner wall of the groove 42, just like the situation when the curved head 401 was initially inserted into the groove 42. At the same time, the repulsive force of the first magnetic block 43 and the second magnetic block 45 assists in pushing the insert 44 to move outward, completely releasing the mechanical lock.

[0062] The synchronous transmission of gear 403 and rack 404 solves the jamming problem caused by uneven force on one side during traditional unlocking, achieving a 100% unlocking success rate. The tapered roller bearing 38 allows plate 30 to rotate slightly when plate 2 35 moves down, ensuring that rod 2 306 and rod 307 are precisely aligned with the trigger point, further reducing the risk of jamming.

[0063] Example 3: Line splitting and fault isolation.

[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the temperature sensor 302 or the vision sensor 303 is activated, it transmits an electrical signal to the control terminal inside the electric push rod 32. The control terminal then controls the electric push rod 32 to start and extend outward. The electric push rod 32 is fixed inside one end of the transverse rail 31, which is fixed horizontally to the outside of the fourth plate 305. Its output end drives the first rod 33 to slide along the transverse rail 31. The first rod 33 pushes the non-fixed end of the external line 304, completely separating it from the docking terminal and cutting off the fault circuit. The cooperation between the electric push rod 32 and the transverse rail 31 enables precise control of line splitting. The splitting distance can be adaptively adjusted according to the line specifications to avoid excessive pulling and damage to the line. The guiding effect of the transverse rail 31 ensures that the first rod 33 slides smoothly and will not cause deviation in the line pushing position due to offset.

[0065] During the downward movement of plate 35, the insert 37 on its outer end face extends outward through the centrifugal force generated by rotation, impacting and squeezing plate 25 sliding in the transverse groove 24 on the outer side of the insulating base 1. The end of the connecting strip 26 fixed on the outer side of plate 25 away from plate 25 is fixed to the outer wall of the isolation chamber 22, causing plate 25 to slide along the transverse groove 24, thereby pulling the isolation chamber 22 to deflect about 90° around the U-shaped rod 21 as the center of rotation. The U-shaped rod 21 is vertically fixed to the top of the insulating base 1, and its top end is fixed to the isolation chamber 22, causing the opening of the isolation chamber 22 to turn towards the control mechanism 3. Subsequently, rod 33 continues to push the free end of the faulty line, sending it completely into the isolation chamber 22. The flame-retardant and arc-resistant structure of the inner wall of the isolation chamber 22 blocks the spread of flames and arcs. The outer sleeve of the U-shaped rod 21 and the spring 23 fixed to the outer wall of the isolation chamber 22 are in a stretched state at this time, providing reserve force for subsequent reset. The deflection and storage design of the isolation chamber 22 saves space compared to a fixed isolation structure; at the same time, the closed design of the isolation chamber 22 ensures that the faulty line is completely isolated from the outside world, preventing the leakage of flames and electric arcs from causing secondary accidents and improving the safety of the power distribution system.

[0066] The working principle of this invention is as follows: Under normal operating conditions, each mechanism of the device first enters a preset stable working state, providing a guarantee for safe transmission of the line. In the locking mechanism 4, the external line 304 is inserted into the fixed sleeve 41 and initially positioned by fitting. Before the initial positioning, the curved part of the curved head 401 will initially press against the inner wall of the groove 42 and extend into the groove 42 together with the insert 44. During the compression process, the curved head 401 will compress the second telescopic rod 48 and the third spring 40 respectively. When the insert 44 is fully inserted into the groove 42, the second telescopic rod 48 on both sides of the insert 44 extends under the action of the third spring 40, driving the curved head 401 to embed into the groove of the inner wall of the fixed sleeve 41. At the same time, the first elastic telescopic rod 46 at the top and bottom of the insert 44 pushes the trapezoidal plate 47 to press against the groove 42, forming a double mechanical lock. The first magnetic block 43 and the second magnetic block 45 in the groove 42 generate a repulsive force due to their same poles, storing the unlocking pre-tightening force.

[0067] The device's real-time monitoring system operates continuously to ensure timely detection of circuit abnormalities. Temperature sensor 302 and vision sensor 303 on the outer side of board 305 both have their detection ends facing the circuit connection point. Temperature sensor 302 collects real-time temperature data at the connection point, while vision sensor 303 monitors for arc discharge through image recognition. When abnormally high temperatures or arc discharge occur at the circuit connection point, the control unit immediately determines a circuit fault and outputs a drive signal to the control mechanism 3 to initiate the unlocking process. The high temperature melts the solder sheet 301, causing the bottom end of connecting bar 39 to be suspended. Then, spring 36, under torsional compression, releases energy, causing board 35 to rotate and move downwards. Board 35, through tapered roller bearing 38, drives board 30 downwards, causing rods 306 and 307 to move downwards synchronously. In this process, the second rod 306 presses against the inclined surface of the trapezoidal plate 47, forcing the trapezoidal plate 47 to contract and causing the first elastic telescopic rod 46 to compress, thus releasing the compression lock. The third rod 307 presses against the extension piece 402, causing the curved head 401 to flip, so that the curved end of the curved head 401 is squeezed and adapted to the inside of the groove 42. Then, under the repulsive force of the first magnetic block 43 and the second magnetic block 45, the curved head 401 is disengaged from the slot. At the same time, the gear 403 in the center of the insert 44 meshes with the racks 404 on both sides to ensure that the trapezoidal plate 47 rises and falls synchronously, avoiding uneven unlocking on one side that could cause jamming, and thus completely releasing the mechanical lock.

[0068] After the lock is released, the control mechanism 3 drives the circuit splitting and conveying action. The electric push rod 32 starts, driving the first rod 33 to slide along the transverse rail 31 away from the docking part. The first rod 33 pushes the non-fixed end of the external line 304, separating it from the docking terminal, thus completing the splitting of the faulty line. At the same time as the line splitting, the isolation mechanism 2 operates synchronously to achieve fault isolation. The insert 37 extends outward from the second plate 35 through the centrifugal force generated by rotation, impacting and squeezing the first plate 25, causing the first plate 25 to slide along the transverse groove 24 of the insulating base 1. The first plate 25 pulls the isolation chamber 22 through the first connecting strip 26, causing the isolation chamber 22 to deflect about 90° around the U-shaped rod 21 as the center of rotation, with the opening facing the line output direction of the control mechanism 3. Subsequently, the first rod 33 continues to push the free end of the faulty line, completely sending it into the interior of the isolation chamber 22. The protective structure of the inner wall of the isolation chamber 22 can block the spread of the burning flame and arc of the faulty line, thus achieving fault isolation.

[0069] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
