Description

Technical Field

[0001] This invention relates to the field of automated testing technology for power distribution equipment, specifically to an automated testing device for power distribution equipment. Background Technology

[0002] To ensure the normal and stable operation of electrical automation equipment, power distribution equipment needs to be installed on the power supply lines of the equipment. Power distribution equipment is a general term for equipment such as high-voltage distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switchgear, distribution panels, switch boxes, and control boxes in the power system. During the installation of power distribution equipment, electrical connection wires need to be connected to the circuit breakers, transformers, and other electrical components of the power distribution equipment. The connection wires and electrical components are generally firmly fixed by tightening the ends of the connection wires with bolts. When a circuit fault occurs, it is necessary to test each connection point of the power distribution equipment. By checking the firmness of the connection between the wires and electrical components, it is possible to quickly determine whether there is a loose connection wire.

[0003] For example, in patent application CN115453250A, an electrical automation testing device for power distribution automation equipment utilizes the tension of clamping springs between two clamping wheels and two sets of guide slides to achieve a preliminary clamping effect on the electrical connection wire. The clamping force is equal to the tension of the clamping springs, and the clamping force on the electrical connection wire remains consistent. When the wire is moved while clamped, if the connection between the electrical connection wire and the components of the power distribution equipment is stable, and the stability is much higher than the clamping force applied by the clamping springs to the two clamping wheels, then the wire cannot pass through the clamping mechanism. A weak clamping force separates the wire from the power distribution equipment components. However, the above-mentioned technical solution relies on the upward pulling action of two clamping wheels to detect the connection strength. Essentially, it judges whether the wire is loose based on the subjective feeling of whether it can be pulled, which has obvious technical limitations and is prone to misjudgment. In addition, this technical solution can only achieve a preliminary detection of the connection strength between the wire and the power distribution equipment components through the upward pulling of the two clamping wheels. When it is found that the wire is indeed loose, it cannot be further processed to reset the wire. That is, it only stays at the detection stage and has no automatic reset clamping mechanism. Relying on manual labor leads to low efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automated detection device for power distribution equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated detection device for power distribution equipment, comprising a body and a coaxial reversing assembly. The coaxial reversing assembly is disposed at the rear end of the body. The coaxial reversing assembly includes a U-shaped frame fixedly installed at the bottom end of the body. The two sides of the U-shaped frame are fixed to the inner wall of the body via guide rods. Driven conical wheels are rotatably installed on both sides of the U-shaped frame recess. A key shaft is coaxially connected to the outer side of the driven conical wheel. A worm gear sleeve is axially slidably installed on the outer side of the key shaft. The keyway in the worm gear sleeve meshes with the key protrusion on the outer circle of the key shaft. The worm gear sleeve is rotatably installed at the bottom end of the movable frame. The two movable frames are elastically connected by a tension spring. A worm wheel is rotatably installed at the top end of the movable frame. The outer teeth of the worm wheel mesh with the outer helix of the worm gear sleeve. A clamping wheel is coaxially connected to the middle of the two worm wheels.

[0006] Furthermore, a motor is bolted to the outside of the machine body, and an output shaft is fixedly connected to the rotating end of the motor. A torque sensor is installed on the output shaft to detect the change in resistance when the wire clamping wheel holds the wire.

[0007] Furthermore, a drive parachute wheel is coaxially fixed at the end of the output shaft, and the drive parachute wheel is rotatably mounted in the middle of the U-shaped frame recess, and the drive parachute wheel is coaxially and reversibly engaged with the driven cone wheels on both sides.

[0008] Furthermore, a key sleeve is coaxially connected to the middle of the drive umbrella wheel, and a keyway is axially opened in the middle of the key sleeve, and the outer diameter of the key sleeve is smaller than the relative surface distance between the two driven cone wheels.

[0009] Furthermore, an automatic reset assembly is provided at the front end of the machine body. The automatic reset assembly includes a second key shaft that engages with the keyway in the key sleeve. The second key shaft slides axially along the keyway in the key sleeve, and a bit is fixedly connected to the end of the second key shaft.

[0010] Furthermore, the automatic reset assembly also includes a bushing radially mounted on the outside of the second key shaft. A frame is fixedly mounted on the bottom of the outer circle of the bushing, and the groove inside the frame is perpendicular to the axial direction of the second key shaft.

[0011] Furthermore, the automatic reset assembly also includes a knob located below the frame. The knob is rotatably mounted on the belly of the machine body, and a protruding pin is fixed on the inner edge of the knob, which slides in conjunction with the groove inside the frame.

[0012] Furthermore, a spacing adjustment component is provided at the top of the interior of the machine body. The spacing adjustment component includes a bracket fixedly installed at the top of the interior of the machine body. A handle is rotatably installed on the inner side of the bracket, and the top of the outer circle of the handle protrudes out of the outer side of the top of the machine body.

[0013] Furthermore, the spacing adjustment assembly also includes a drive shaft coaxially fixed in the middle of the handle, with a cam fixedly connected to the end of the drive shaft away from the handle, and the outer edge of the cam tightly fitting against the opposite sidewalls of the two movable frames under the action of the tension spring.

[0014] Furthermore, the machine body is provided with power distribution components, and the upper and lower ends of the power distribution components are fixed with terminals. The terminals are screwed together with the screwdriver bit. The terminals are connected to wiring lines and locked by the wiring screws. The wiring lines are located inside the wire clamping wheels on both sides.

[0015] This invention provides an automated detection device for power distribution equipment, which has the following beneficial effects; 1. In use, this application uses a torque sensor mounted on the motor output shaft to detect changes in resistance when the wire clamping wheel holds the wire. When the wire connection is secure, the wire is stably clamped, there is no relative slippage between the wire clamping wheel and the wire, the torque is stable, and the rotation speeds on both sides are consistent. When the wire becomes loose, the wire will slip slightly with the wire clamping wheel, the torque will suddenly decrease, and if the speed difference between the two wheels exceeds a threshold, it is considered loose. The judgment standard has been transformed from the subjective feeling of whether it can be moved to the objective judgment of the torque sensor in this application. The torque sensor can monitor changes in resistance when the wire clamping wheel holds the wire in real time. Even if there is only a slight slippage in the wire, it can be quickly captured by the signal of a sudden decrease in torque. The looseness detection is more accurate, preventing the looseness from developing into serious faults such as poor contact or short circuit.

[0016] 2. When this application is in use, the motor is activated and reversed, so that the outward pulling force originally applied by the clamping wheels on both sides is reversed into a pushing force that pushes the wire into the terminal. In addition, the motor also drives the coaxial key sleeve in the middle of the drive umbrella wheel to rotate through the output shaft. Then, under the meshing transmission action of the keyway in the key sleeve and the key shaft two, the loose wire screw is tightened by the bit at the end of the key shaft two, eliminating the previously detected wire looseness. Compared with the existing technology, which can only complete the looseness detection and requires manual opening of the cover, power off, and resetting of the clamp, resulting in response lag and cumbersome operation, this solution constructs a functional closed loop of detection and processing through mechanical structure linkage and motor reverse drive. It eliminates looseness from two dimensions: wire reset and terminal locking. The entire process does not require manual contact with the wire or components, thus improving processing efficiency and operational safety.

[0017] 3. When using this application, the control device positions the two clamping wheels on both sides of the wiring to be tested on the power distribution components. After the reset cam is activated, the clamping wheels on both sides clamp the wiring to be tested under the action of the tension spring. The user can easily control the sliding of the movable frame on both sides by turning the handle to rotate the cam, and freely adjust the distance between the clamping wheels without replacing any parts. This can adapt to the testing needs from thin wires to thick wires, reducing the cost of multi-specification adaptation of the equipment. Through simple mechanical structure linkage, full specification compatibility of wires in the power distribution cabinet is achieved. Attached Figure Description

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 4 to 6This invention provides a technical solution: an automated detection device for power distribution equipment, comprising a body 1 and a coaxial reversing assembly 7. A motor 2 is bolted to the outside of the body 1, and an output shaft 3 is fixedly connected to the rotating end of the motor 2. A torque sensor 4 is mounted on the output shaft 3 to detect changes in resistance when the wire clamping wheel 709 clamps the wire. A drive parapet wheel 5 is coaxially fixed to the end of the output shaft 3, and the drive parapet wheel 5 is rotatably mounted in the middle of the recess of a U-shaped frame 701. The drive parapet wheel 5 coaxially and reversibly meshes with the driven conical wheels 703 on both sides. The coaxial reversing assembly 7 is located at the rear end inside the body 1. The coaxial reversing assembly 7 includes a U-shaped frame 701 fixedly mounted at the bottom end inside the body 1. Both sides are fixed to the inner wall of the machine body 1 by guide rods 702, and driven cone wheels 703 are rotatably installed on both sides of the U-shaped frame 701 notch. A key shaft 704 is coaxially connected to the outer side of the driven cone wheel 703, and a worm sleeve 705 is axially slidably installed on the outer side of the key shaft 704. The keyway in the middle hole of the worm sleeve 705 meshes with the key protrusion on the outer circle of the key shaft 704. The worm sleeve 705 is rotatably installed at the bottom of the movable frame 706, and the two movable frames 706 are elastically connected by tension springs 707. A worm wheel 708 is rotatably installed at the top of the movable frame 706, and the outer circle teeth of the worm wheel 708 mesh with the outer circle helix of the worm sleeve 705. A wire clamping wheel 709 is coaxially connected to the middle of the two worm wheels 708. The specific operation is as follows: Start motor 2 and drive drive parapet wheel 5 to rotate through output shaft 3. Under the meshing transmission of drive parapet wheel 5 and driven cone wheel 703 on both sides of U-shaped frame 701 notch, drive key shaft 704 on both sides to rotate in opposite directions. Worm sleeve 705 sliding axially on the outside of key shaft 704 meshes with key protrusion on the outer circle of key shaft 704 through central keyway, so that the spacing adjustment component 9 can adjust the spacing of wire clamping wheels 709 on both sides while maintaining power transmission from key shaft 704 to worm sleeve 705, so as to adapt to the detection requirements of wires 12 with different diameters. When key shaft 704 drives worm sleeve 705 to rotate, under the meshing transmission of outer spiral of worm sleeve 705 and outer gear teeth of worm wheel 708, drive wire clamping wheel 709 coaxial in the middle of worm wheel 708 on both sides to rotate in opposite directions. By prying the wire outward, this application can detect the change in resistance when the wire clamping wheel 709 clamps the wire by adding a torque sensor 4 to the output shaft 3 of the motor 2. When the wire is firmly connected, the wire is stably clamped, there is no relative slippage between the wire clamping wheel 709 and the wire, the torque is stable, and the rotation speed on both sides is consistent. When the wire is loose, the wire will slip slightly with the wire clamping wheel 709, the torque will suddenly decrease, and if the speed difference between the two wheels exceeds the threshold, it is judged as loose. The judgment standard is changed from the original subjective feeling of whether it can be pried open to the objective judgment of the torque sensor 4 of this application. The torque sensor 4 can monitor the change in resistance when the wire clamping wheel 709 clamps the wire in real time. Even if there is only a slight slippage in the wire, it can be quickly captured by the signal of sudden decrease in torque. The looseness detection is more accurate and avoids the looseness from developing into serious faults such as poor contact and short circuit. Please see Figures 5 to 7 A key sleeve 6 is coaxially connected to the middle of the drive parachute wheel 5, and a keyway is axially formed in the middle of the key sleeve 6. The outer diameter of the key sleeve 6 is smaller than the distance between the opposite surfaces of the driven cone wheels 703 on both sides. An automatic reset assembly 8 is provided at the front end of the machine body 1. The automatic reset assembly 8 includes a second key shaft 801 that engages with the keyway in the middle hole of the key sleeve 6. The second key shaft 801 slides axially along the keyway in the middle hole of the key sleeve 6, and a screwdriver bit 802 is fixedly connected to the end of the second key shaft 801. The automatic reset assembly 8 also includes a diameter A bushing 803 is installed outside the key shaft 2 801. A frame 804 is fixedly installed on the bottom of the outer circle of the bushing 803. The groove inside the frame 804 is perpendicular to the axis of the key shaft 2 801. The automatic reset assembly 8 also includes a knob 805 located below the frame 804. The knob 805 is rotatably installed on the belly of the machine body 1. A protruding pin 806 is fixed on the inner edge of the knob 805. The protruding pin 806 slides in cooperation with the groove inside the frame 804. The specific operation is as follows: When the inspection reveals that the wiring is indeed loose, the user rotates the knob 805 at the bottom of the machine body 1. The inner protrusion 806 of the knob 805 slides within the groove of the frame 804, which in turn causes the key shaft 801 to move axially forward within the hole of the key sleeve 6 via the bushing 803. This causes the bit 802 at the end of the key shaft 801 to engage with the threaded screw of the terminal 11. At this point, the motor 2 is activated again and reversed, causing the outward pulling force originally applied by the wire clamping wheels 709 on both sides to be reversed and converted into a pushing force that tightens the wiring into the terminal 11. Furthermore, the motor 2 also drives the output shaft 3... The key sleeve 6, which is coaxial with the middle of the driving umbrella wheel 5, rotates. Then, under the meshing transmission action of the keyway in the hole of the key sleeve 6 and the key shaft 801, the loose wiring screw is tightened by the bit 802 at the end of the key shaft 801, eliminating the previously detected loose wiring. Compared with the existing technology, which can only complete the looseness detection and requires manual opening of the cover, power off, and reset clamping afterward, resulting in lag and cumbersome operation, this solution constructs a functional closed loop of detection and processing through mechanical structure linkage and reverse drive of motor 2. It eliminates looseness from two dimensions: wire reset and terminal locking. The entire process does not require manual contact with wires or components, improving processing efficiency and operational safety. Please see Figures 1 to 3The machine body 1 has a spacing adjustment component 9 at its top. The spacing adjustment component 9 includes a bracket 901 fixedly installed at the top of the machine body 1. A handle 902 is rotatably installed on the inner side of the bracket 901. The top of the outer circle of the handle 902 protrudes from the outer side of the top of the machine body 1. The spacing adjustment component 9 also includes a transmission shaft 903 coaxially fixed in the middle of the handle 902. A cam 904 is fixedly connected to one end of the transmission shaft 903 away from the handle 902. The outer edge of the cam 904 is tightly fitted to the opposite side wall of the movable frame 706 on both sides under the elastic force of the tension spring 707. The machine body 1 has a power distribution component 10 on its exterior. The upper and lower ends of the power distribution component 10 are fixed with terminals 11. The terminal screws of the terminals 11 are tightened with the bit 802. A wiring line 12 is inserted into the end of the terminal 11 and locked by the terminal screw. The wiring line 12 is located inside the wire clamping wheels 709 on both sides. The specific operation is as follows: The user turns the top of the handle 902, which protrudes from the outer side of the top of the body 1, and drives the cam 904 to rotate through the transmission shaft 903. When the protruding parts on both sides of the cam 904 abut against the opposite sidewall of the movable frame 706, the two movable frames 706 overcome the elastic force of the tension spring 707 and slide axially on the corresponding key shaft 704, thereby realizing the outward movement of the two wire clamping wheels 709 and increasing the distance between the two wire clamping wheels 709. Then, the control device makes the two wire clamping wheels 709 position within the power distribution components. On both sides of the wire 12 to be tested, after the reset cam 904 is activated, the clamping wheels 709 on both sides clamp the wire 12 to be tested under the elastic force of the tension spring 707. The user can easily control the sliding of the movable frame 706 on both sides by turning the handle 902 to drive the cam 904 to rotate, and freely adjust the distance of the clamping wheels 709 without replacing any parts. This can adapt to the testing needs of wires from thin to thick, reducing the cost of multi-specification adaptation of the equipment. Through simple mechanical structure linkage, full specification compatibility of wires in the distribution cabinet is achieved.

[0021] In summary, when using this automated detection device for power distribution equipment: First, the user turns the top of the handle 902, which protrudes from the outer side of the top of the body 1, and drives the cam 904 to rotate via the transmission shaft 903. When the protruding parts on both sides of the cam 904 abut against the opposite sidewalls of the movable frame 706, the two movable frames 706 overcome the elastic force of the tension spring 707 and slide axially on the corresponding key shaft 704, thereby realizing the outward movement of the two wire clamping wheels 709 and increasing the distance between the two wire clamping wheels 709. Then, the control device positions the two wire clamping wheels 709 at the power distribution component 10. On both sides of the wire 12 being tested, after the reset cam 904 is activated, the clamping wheels 709 on both sides clamp the wire 12 being tested under the elastic force of the tension spring 707. The user can easily control the sliding of the movable frame 706 on both sides by turning the handle 902 to drive the cam 904 to rotate, and freely adjust the distance of the clamping wheels 709 without replacing any parts. This can adapt to the testing needs from thin wires to thick wires, reduce the multi-specification adaptation cost of the equipment, and achieve full specification compatibility of wires in the distribution cabinet through simple mechanical structure linkage. Secondly, the motor 2 is started and drives the drive umbrella wheel 5 to rotate through the output shaft 3. Under the meshing transmission between the drive umbrella wheel 5 and the driven cone wheels 703 on both sides of the U-shaped frame 701 notch, the key shafts 704 on both sides are further driven to rotate in opposite directions. The worm sleeve 705, which slides axially on the outside of the key shaft 704, meshes with the key protrusion on the outer circle of the key shaft 704 through the keyway in the middle hole. This allows the spacing adjustment component 9 to adjust the spacing of the wire clamping wheels 709 on both sides while maintaining the power transmission from the key shaft 704 to the worm sleeve 705, so as to adapt to the detection requirements of wires 12 with different diameters. When the key shaft 704 drives the worm sleeve 705 to rotate, under the meshing transmission between the outer spiral of the worm sleeve 705 and the outer teeth of the worm wheel 708, the wire clamping wheels 709, which are coaxial in the middle of the worm wheels 708 on both sides, rotate in the opposite direction to pull the wire... When the wire is pulled outward, this application adds a torque sensor 4 to the output shaft 3 of the motor 2 to detect the change in resistance when the wire clamping wheel 709 clamps the wire. When the wire is firmly connected, the wire is stably clamped, there is no relative slippage between the wire clamping wheel 709 and the wire, the torque is stable, and the speed on both sides is consistent. When the wire is loose, the wire will slip slightly with the wire clamping wheel 709, the torque will suddenly decrease, and the speed difference between the two wheels will exceed the threshold, which is judged as loose. The judgment standard is changed from the original subjective feeling of whether it can be pulled to the objective judgment of the torque sensor 4 of this application. The torque sensor 4 can monitor the change in resistance of the wire clamping wheel 709 clamping the wire in real time. Even if there is only a slight slippage in the wire, it can be quickly captured by the signal of sudden decrease in torque. The looseness detection is more accurate and avoids the looseness from developing into serious faults such as poor contact and short circuit. Finally, when the inspection revealed that the wiring was indeed loose, the user rotated the knob 805 at the bottom of the machine body 1. This caused the inner protrusion 806 of the knob 805 to slide within the groove of the frame 804, which in turn caused the key shaft 801 to move axially forward within the hole of the key sleeve 6 via the bushing 803. This caused the bit 802 at the end of the key shaft 801 to engage with the threaded screw of the terminal 11. At this point, the motor 2 was activated again and reversed, causing the outward pulling force originally applied by the wire clamping wheels 709 on both sides to be reversed and converted into a pushing force that tightens the wiring into the terminal 11. Furthermore, the motor 2 also drove the drive via the output shaft 3. The key sleeve 6, which is coaxial with the middle of the parapet wheel 5, rotates. Then, under the meshing transmission action of the keyway in the key sleeve 6 and the key shaft 801, the loose wiring screw is tightened by the bit 802 at the end of the key shaft 801, eliminating the previously detected loose wiring. Compared with the existing technology, which can only complete the looseness detection and requires manual opening of the cover, power off, and reset clamping afterward, resulting in lag and cumbersome operation, this solution constructs a functional closed loop of detection and processing through mechanical structure linkage and reverse drive of motor 2. It eliminates looseness from two dimensions: wire reset and terminal locking. The entire process does not require manual contact with wires or components, thus improving processing efficiency and operational safety.
