Detailed ways

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

The lower end of each relay 14 is connected with three output wires 15 in parallel, and the output wires 15 are vertically arranged on the lower end of the relay mounting frame 13 through a U-shaped frame 16, the output wires 15 are cut off at the position between the two side sections of the U-shaped frame 16, and the output wires 15 at both ends are connected by a conductive plate 17, a first spring rod 18 is fixedly connected between the conductive plate 17 and the middle section of the U-shaped frame, a space moving device 2 is arranged in the cabinet 1, and a voltage and current measuring module 3 is arranged on the space moving device 2.

It should be noted that the present invention measures the voltage across the relay 14 and the current passing through the relay 14 through the current and voltage module. When measuring the sub-line 19 acting as the live wire and the output line 15, the voltage between the sub-line 19 and the output line 15 is very large. When there is no current, it can be determined that the relay 14 is open-circuited. When there is no voltage difference across the relay 14, it can be determined that the relay 14 is short-circuited, which means that the relay 14 has no function of continuing to protect the circuit. The relay 14 should be replaced in time. At the same time, the position of the voltage and current measurement module 3 can be changed through the space moving device 2, so as to measure the current and voltage of multiple relays 14.

As shown in Figures 1, 2 and 10, the space moving device 2 includes a front and rear sliding guide rail 21, a left and right sliding guide rail 22 and a vertical sliding guide rail 23. The front and rear sliding guide rails 21 are fixedly installed on the left and right sides of the interior of the cabinet 1. The left and right sliding guide rails 22 are slidably connected to the front and rear sliding guide rails 21. A pushing gas rod 24 is fixedly installed between the left and right sliding guide rails 22 and the rear side of the inner wall of the cabinet 1. The vertical sliding guide rail 23 is slidably connected to the left and right sliding guide rails 22. A lateral moving screw 2 is rotatably mounted on the left and right sliding guide rails 22. 5, the lateral moving screw 25 is threadedly connected to the vertical sliding guide rail 23, one side of the left and right sliding guide rails 22 is fixedly connected with a first motor 26 for driving the lateral moving screw 25 to rotate, the vertical sliding guide rail 23 is vertically slidably connected with a voltage and current measuring module 3, a vertical moving screw 27 is mounted in the vertical sliding guide rail 23 for rotating along the vertical direction, the vertical moving screw 27 is threadedly connected to the voltage and current measuring module 3, and the upper end of the vertical sliding guide rail 23 is fixedly connected with a second motor 28 for driving the vertical moving screw 27 to rotate.

It should be noted that when adjusting the position of the voltage and current measuring module 3 in the left and right directions, the first motor 26 drives the rotation of the transverse moving screw 25, and the transverse moving screw 25 is threadedly connected to the vertical sliding guide rail 23, thereby driving the vertical sliding guide rail 23 to slide in the left and right directions and thus adjusting the position of the voltage and current measuring module 3 in the left and right directions. The second motor 28 drives the vertical moving screw 27 to move in the vertical direction, thereby adjusting the position of the voltage and current measuring module 3 in the vertical direction. The gas rod 24 is pushed to drive the left and right sliding guide rails 22 to slide in the front and rear directions, thereby controlling the contact and disconnection of the voltage and current measuring module 3 with the sub-line 19 and the output line 15, thereby measuring the current and voltage.

As shown in Figures 3 to 9, the voltage and current measuring module 3 includes a vertical sliding plate 31, a current measuring device 32, a voltage measuring device 33 and a deflection control device 34. The vertical sliding plate 31 is slidably connected to the vertical sliding guide rail 23 in the vertical direction and is threadedly connected to the vertical moving screw 27. The voltage measuring device 33 is arranged at the upper end of the vertical sliding plate 31, and the current measuring device 32 is arranged at the lower end of the vertical sliding plate 31. The vertical sliding plate 31 is also connected to a deflection control device 34 for steering and fixing the voltage measuring device 33.

It should be noted that when the current and voltage are measured by the voltage and current measuring module 3, the current of the line is measured by the current measuring device 32, and the voltage at both ends of the relay 14 is measured by the voltage measuring device 33. The voltage measuring device 33 is controlled by the deflection control device 34 to deflect and fix the direction, so that the voltage measuring module can measure the voltage between the sub-wires 19 acting as the neutral wire and the live wire. If there is no voltage difference between the neutral wire and the live wire, it can be said that the relay 14 and the circuit are short-circuited. This situation has a great impact on safety and requires immediate wall circuit repair and replacement of the damaged relay 14 and related electrical appliances.

As shown in FIGS. 3 , 5 and 6 , the voltage measuring device 33 includes a device mounting plate 331, the device mounting plate 331 is connected to the deflection control device 34, the device mounting plate 331 is provided with a position conversion groove 3311 in the vertical direction, and a position conversion slider 332 is symmetrically slidably connected in the upper and lower directions in the position conversion groove 3311, and the device mounting plate 331 is provided with screw mounting grooves 3312 corresponding to the position conversion groove 3311 on both sides of the position conversion groove 3311, and each of the two screw mounting grooves 3312 rotates A position conversion screw 333 is connected, and the two position conversion screws 333 are respectively threadedly connected to the two position conversion sliders 332. The upper ends of the two position conversion screws 333 are respectively fixedly connected to a position conversion gear 334. The two position conversion gears 334 are meshed with each other, and the upper end of one of the position conversion gears 334 is fixedly connected with a rotating disk 335. The position conversion sliders 332 correspond to the sub-line 19 at the upper end of the relay 14 and the output line 15 at the lower end of the relay 14, respectively. A voltage measuring mechanism 336 is installed on the position conversion slider 332.

It should be noted that when adjusting the voltage measuring device 33 to make it suitable for the relay 14, the rotating disk 335 is rotated, and the rotating disk 335 drives the conversion gear fixedly connected to it to be fixedly connected, and the two conversion gears engage with each other to produce rotations in opposite directions, thereby causing the two position conversion screws 333 to rotate in opposite directions, thereby causing the two position conversion sliders 332 to move in opposite directions, so that the voltage measuring mechanism 336 measures the voltage between the sub-line 19 and the output line 15 at both ends of the relay 14.

As shown in Figures 3 and 5, the voltage measuring mechanism 336 includes a measuring fixed block 3361, an extended detection rod 3362, a fixed detection rod 3363, a first detection spring 3364 and a voltage measuring wire 3365. The measuring fixed block 3361 is fixedly installed on the position changing slider 332. The end of the position changing slider 332 close to the relay 14 is fixedly connected to the measuring fixed block 3361. The measuring fixed block 3361 is fixedly connected to the fixed detection rod 3363. The fixed detection rod 3363 is slidably connected to the extended detection rod 3364. Rod 3362, a first detection spring 3364 is arranged in the fixed detection rod 3363, two ends of the first detection spring 3364 are respectively fixedly mounted on the extended detection rod 3362 and the measuring fixed block 3361, a voltage measuring sensor 337 is fixedly mounted on the device mounting plate 331, and a voltage measuring wire 3365 is fixedly connected to the end of the extended detection rod 3362, and the voltage measuring wire 3365 passes through the interior of the fixed detection rod 3363 and the measuring fixed block 3361 and is connected to the voltage measuring sensor 337.

It should be noted that in the process of measuring voltage through the voltage measuring mechanism 336, the detection rod 3362 is extended to contact the sub-line 19 and the output line 15 at both ends of the relay 14 respectively, and the detection rod 3362 is connected to the voltage measurement sensor 337 through voltage guidance. When the voltage measurement sensor 337 obtains the voltage information, it transmits the voltage signal to the control terminal operated by the staff. In the process of the detection rod 3362 being extended to contact the sub-line 19 and the output line 15, the first detection spring 3364 can press the detection rod 3362 against the sub-line 19 and the output line 15, and at the same time avoid hard impact between the detection rod 3362 and the sub-line 19 and the output line 15.

As shown in Figures 7 and 8, the deflection control device 34 includes a deflection control rod 341, a deflection control disk 342, a control spring 343 and a locking disk 344. The deflection control disk 342 is fixedly connected to the device mounting plate 331, and the vertical sliding plate 31 is fixedly connected to a locking disk 344 on the outer side of the deflection control disk 342. The deflection control disk 342 is provided with a deflection control groove 3421 along its radial direction, and a locking groove 3441 is respectively provided on the upper side and the right side of the locking disk 344. A deflection control rod 341 is slidably connected in the deflection control groove 3421, and the deflection control rod 341 is inserted into one of the locking grooves 3441. A control spring 343 is fixedly connected between the deflection control rod 341 and the bottom surface of the deflection control groove 3421.

It should be noted that when the voltage measuring device 33 is changed from a vertical state to a horizontal state through the deflection control device 34, the deflection control rod 341 is pulled out from the upper locking groove 3441, and the device mounting plate 331 is rotated to change the device mounting plate 331 from a horizontal state to a vertical state. Under the top pressure of the control spring 343, the deflection control rod 341 will be inserted into the locking groove 3441 on the right side, thereby fixing the device mounting plate 331 in a horizontal state, so that the voltage measuring device 33 can be used to measure the voltage between the sub-wire 19 acting as the neutral wire and the live wire.

As shown in Figures 3, 4, 7 and 9, the current measuring device 32 includes a current measuring plate 321, a current measuring screw 322 and a current measuring screw sleeve 323. The current measuring screw 322 is slidingly connected to the vertical sliding plate 31 along the front-to-back direction, the current measuring screw sleeve 323 is rotationally connected to the vertical sliding plate 31, and the current measuring screw sleeve 323 is threadedly connected to the current measuring screw 322.

A current measuring sensor 324 is fixedly installed on the vertical sliding plate 31. The upper and lower conductive areas of the current measuring plate 321 are each connected to a current measuring wire 325, and the current measuring wire 325 is connected to the current measuring sensor 324.

It should be noted that, in the process of measuring the current flowing through the relay 14, the current measuring plate 321 will squeeze out the conductive plate 17, and the current measuring sensor 324 will be connected to the output line 15 through the insulating area on the current measuring plate 321 and the current measuring wire 325, so as to measure the current, and the current measuring sensor 324 will transmit the current data signal to the control terminal.

As shown in FIG. 1 and FIG. 2 , a plurality of optical stop sensors 4 are evenly arranged on the left and right sliding guide rails 22 .

When the vertical sliding guide rail 23 moves to a position corresponding to the optical stop sensor 4 , the second motor 28 stops rotating, so that the current and voltage measuring mechanism 336 corresponds exactly to the sub-line 19 and the output line 15 on the relay 14 .

The working principle of the present invention is that the present invention measures the voltage at both ends of the relay 14 and the current passing through the relay 14 through the current and voltage module. When measuring the sub-line 19 acting as the live wire and the output line 15, the voltage between the sub-line 19 and the output line 15 is very large. When there is no current, it can be determined that the relay 14 is open-circuited. When there is no voltage difference at both ends of the relay 14, it can be determined that the relay 14 is short-circuited, which further indicates that the relay 14 has no function of continuing to protect the circuit. At the same time, the position of the voltage and current measurement module 3 can be changed by the space moving device 2, so as to measure the current and voltage of multiple relays 14. When the current and voltage are measured by the voltage and current measurement module 3, the current of the line is measured by the current measuring device 32, and the voltage at both ends of the relay 14 is measured by the voltage measuring device 33. The deflection control device 34 is controlled The voltage measuring device 33 is deflected and fixed in direction, so that the voltage measuring module can measure the voltage between the sub-line 19 serving as the neutral line and the live line. If there is no voltage difference between the neutral line and the live line, it can be said that the relay 14 and the circuit are short-circuited. This situation has a great impact on safety and requires immediate wall circuit repair and replacement of the damaged relay 14 and related electrical appliances. When adjusting the voltage measuring device 33 to make it suitable for the relay 14, the rotating disk 335 is rotated, and the rotating disk 335 drives the conversion gear fixedly connected thereto to be fixedly connected. The two conversion gears mesh with each other to produce opposite rotations, thereby causing the two position conversion screws 333 to rotate in opposite directions, thereby causing the two position conversion sliders 332 to move in opposite directions, thereby causing the voltage measuring mechanism 336 to measure the sub-line 19 and the output line at both ends of the relay 14. 15 is measured. In the process of measuring the voltage through the voltage measuring mechanism 336, the detection rod 3362 is extended to contact the sub-line 19 and the output line 15 at both ends of the relay 14 respectively. The detection rod 3362 is connected to the voltage measurement sensor 337 through the voltage guide. When the voltage information is obtained, the voltage measurement sensor 337 transmits the voltage signal to the control terminal operated by the staff. In the process of extending the detection rod 3362 to contact the sub-line 19 and the output line 15, the first detection spring 3364 can press the extended detection rod 3362 against the sub-line 19 and the output line 15, and at the same time avoid hard impact between the extended detection rod 3362 and the sub-line 19 and the output line 15. In the process of measuring the current flowing through the relay 14, the current measuring plate 321 will squeeze the conductive plate 17 out, and the conductive plate 17 will be connected to the conductive plate 17 through the insulating area on the current measuring plate 321 and the measuring current. The current measuring wire 325 connects the current measuring sensor 324 with the output line 15, thereby measuring the current. The current measuring sensor 324 transmits the current data signal to the control terminal. In this process, when adjusting the position of the voltage and current measuring module 3 in the left and right directions, the first motor 26 drives the rotation of the lateral moving screw 25, and the lateral moving screw 25 is threadedly connected to the vertical sliding guide rail 23, thereby driving the vertical sliding guide rail 23 to slide in the left and right directions and thereby adjusting the position of the voltage and current measuring module 3 in the left and right directions. The second motor 28 drives the vertical moving screw 27 to move in the vertical direction, thereby adjusting the position of the voltage and current measuring module 3 in the vertical direction. The gas rod 24 is pushed to drive the left and right sliding guide rails 22 to slide in the front and rear directions, thereby controlling the contact and disconnection of the voltage and current measuring module 3 with the sub-line 19 and the output line 15, thereby measuring the current and voltage.
