However, during long-term use, the detection needles are often exposed to the external environment and are easily contaminated with dust and other impurities. These dust and impurities will adhere to the contact points of the detection needles, increase the contact resistance, and cause poor contact during the meter detection process.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides an inner detection needle and a movable cylinder. When the current conduction is abnormal, the movable cylinder is driven to rotate by the rotating arm. At this time, the inner detection needle will gradually leak out of the movable cylinder. After the rotating arm is rotated and fixed vertically, the horizontal state of the movable cylinder is also fixed. Then the control end continues to drive the electric telescopic rod to drive the lifting frame and the detection rod assembly to move downward. At this time, the contact of the inner detection needle can directly abut against the electric meter below, and conduct current to the electric meter through the inner detection needle. When the electric meter detects normally, it can be determined that the outer detection needle is released poorly. When the electric meter detects still abnormally, it can be determined that the electric meter has defects. This design can realize that when the outer detection needle has poor contact, the inner detection needle replaces the outer detection needle to continue to detect the defects of the electric meter, thereby improving the measurement accuracy of the electric meter parameters and avoiding the problem of misjudgment of electric meter defects.

[0019] 2. The present invention sets a wiping cotton and a lower pressure plate. When the current conduction is abnormal, the control end turns on the electromagnetic plate. At this time, the electromagnetic plate will generate a magnetic repulsion force and push the magnetic block, the moving rod and the lower pressure plate to move downward. At this time, the spring three is compressed, and then the control end drives the electric telescopic rod to drive the lifting frame, the detection rod assembly and the detection needle assembly to rise and reset. Due to the rise of the detection needle assembly, the round rod can be abutted against the lower pressure plate after it is lowered, and is squeezed by the lower pressure plate, driving the rotating arm and the movable cylinder to rotate. At this time, the arc-shaped elastic member is compressed, and due to the rotation of the movable cylinder, the insulating protrusion can be When the outer detection needle is in contact with the inner detection needle, the insulating protrusion is squeezed and moved outward by the inner detection needle. At this time, the spring 1 is compressed, so that the inner detection needle can pass through between the insulating protrusions and emerge from the inside of the movable cylinder. After the detection rod assembly rises and resets, the rotating arm will rotate to vertical, and the movable cylinder will rotate to horizontal. During the rotation of the movable cylinder, the outer detection needle will pass through the wiping cotton 1, and the contact of the outer detection needle will be wiped on the wiping cotton 1, so that impurities on the contact of the outer detection needle can be wiped off, and then the impurity cleaning operation of the outer detection needle can be realized, so that the outer detection needle can be used continuously in the future.

[0020] 3. The present invention sets an external detection needle and an inclined surface block. When the internal detection needle detects the electric meter, the control end will close the electromagnetic plate. At this time, due to the elastic recovery effect of the spring three, the magnetic block, the connecting plate, the moving rod and the lower pressure plate can be pushed to reset upward. Due to the movement of the connecting plate, the abutment plate and the piston rod two can be pushed to move upward, and the piston rod one and the inclined surface block can be squeezed downward by air pressure. At this time, the tension spring is stretched, and then the control end drives the electric telescopic rod to drive the lifting frame and the detection rod assembly to move upward and reset. During the movement, the cone sleeve can be abutted against the piston rod one, and can be squeezed by the inclined surface of the piston rod one and push the cone sleeve and the clamping rod to rotate. The arm moves inwardly, and spring 2 is compressed, so that the clamping rod is disengaged from the outside of the top block, thereby releasing the fixing effect of the rotating arm. Due to the elastic recovery effect of the arc-shaped elastic member, the movable cylinder and the rotating arm can be pushed to rotate and reset, and the inner detection needle can be stored in the movable cylinder again and abut against the outer detection needle. During the resetting of the movable cylinder, the inner detection needle will pass through the wiping cotton 2 and wipe on the wiping cotton 2 to prevent the contact of the inner detection needle from being contaminated with dust and impurities. At the same time, the movable cylinder is reset, so that the device can continue to use the outer detection needle for detection operations, thereby preventing the inner detection needle from being contaminated with dust during long-term use.

[0036] like Figures 1 to 13 As shown, the present invention provides a smart meter defect detection device, which is characterized by comprising a transmission mechanism 1, a mounting frame 2, a detection assembly 3, an electric telescopic rod 4, a lifting frame 5, a detection rod assembly 6, a connecting line 7 and a detection needle assembly 8;

[0038] The detection rod assembly 6 includes a sleeve rod 61, which is installed on the lifting frame 5. The bottom end of the sleeve rod 61 extends to the bottom of the mounting frame 2. The outer portion of the sleeve rod 61 is fixedly sleeved with a fixing sleeve 62 located below the mounting frame 2. The inner portion of the sleeve rod 61 is fixedly sleeved with a straight guide rod 63. One end of the straight guide rod 63 is connected to the connecting line 7. The other end of the straight guide rod 63 extends to the inside of the fixing sleeve 62 and is connected to an arc guide rod 64 located outside the fixing sleeve 62. The outer portion of the arc guide rod 64 is sleeved with an arc elastic member 65. One end of the arc elastic member 65 is connected to the fixing sleeve 62. The other end of the arc guide rod 64 is connected to an inner detection needle 69.

[0039] The detection needle assembly 8 includes a movable cylinder 81, which is movably mounted on the sleeve rod 61. The movable cylinder 81 is movably sleeved on the arc guide rod 64. The inner detection needle 69 is located in the movable cylinder 81. The outer detection needle 82 is fixedly sleeved at the lower part of the interior of the movable cylinder 81. The inner detection needle 69 abuts against the outer detection needle 82. The other end of the arc-shaped elastic member 65 is connected to the movable cylinder 81.

[0040] The above scheme is adopted: when the current conduction is abnormal, the control end drives the movable cylinder 81 to rotate, and the inner detection needle 69 will gradually leak out from the movable cylinder 81. After the horizontal state of the movable cylinder 81 is fixed, the control end continues to drive the electric telescopic rod 4 to drive the lifting frame 5 and the detection rod assembly 6 to move downward. At this time, the contact of the inner detection needle 69 can directly contact the electric meter below, and conduct current to the electric meter through the inner detection needle 69. When the electric meter detects normally, it can be determined that the outer detection needle 82 is released. When the electric meter detects still abnormally, it can be determined that the electric meter has defects.

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, one side of the movable sleeve inside the movable cylinder 81 is connected to two insulating protrusions 85 that abut against each other and can close the movable cylinder 81, and the upper and lower sides of the outer sides of the insulating protrusions 85 are connected to limit rods 86, and the other end of the limit rod 86 extends to the outside of the movable cylinder 81. The outer side of the limit rod 86 is sleeved with a spring 87, one end of the spring 87 is connected to the insulating protrusion 85, and the other end of the spring 87 is connected to the movable cylinder 81.

[0042] By adopting the above scheme, due to the rotation of the movable cylinder 81, the insulating protrusion 85 can be brought into contact with the inner detection needle 69, and then the insulating protrusion 85 is squeezed and moved outward by the inner detection needle 69. At this time, the spring 1 87 is compressed, so that the inner detection needle 69 can pass through between the insulating protrusions 85 and be exposed from the inside of the movable cylinder 81. When the inner detection needle 69 is in the movable cylinder 81, it can be closed by the insulating protrusion 85.

[0043] like Figure 3 As shown, one side of the movable cylinder 81 is connected to an arc block 2 83 located below the insulating protrusion 85, and the upper part of the arc block 2 83 is connected to a wiping cotton 2 84. The outer side of the fixed sleeve 62 is connected to a fixing frame 66 away from the side of the arc block 2 83, and the lower part of the fixing frame 66 is connected to an arc block 1 67, and the side of the arc block 1 67 facing the movable cylinder 81 is connected to a wiping cotton 1 68.

[0044] The above scheme is adopted: during the rotation of the movable cylinder 81, the outer detection needle 82 will pass through the wiping cotton 68, and the contact of the outer detection needle 82 will be wiped on the wiping cotton 68, so that the impurities on the contact of the outer detection needle 82 can be wiped off; during the resetting of the movable cylinder 81, the inner detection needle 69 will pass through the wiping cotton 84, and be wiped on the wiping cotton 84, so that the impurities on the contact of the inner detection needle 69 can be wiped off.

[0045] like Fig.11 As shown, the movable cylinder 81 is coaxially connected to the rotating arm 88, and a round rod 89 is fixedly sleeved on one side of the interior of the rotating arm 88, and one end of the round rod 89 extends to the outside of the rotating arm 88, and a clamping rod 810 is movably sleeved on the other side of the interior of the rotating arm 88, and one side of the clamping rod 810 extends to the outside of the rotating arm 88 and faces the movable cylinder 81, and the other end of the clamping rod 810 is connected to a spring 2 812, and the other end of the spring 2 812 is connected to the rotating arm 88, and the outside of the clamping rod 810 is fixedly sleeved with a conical sleeve 811 located outside the rotating arm 88.

[0046] With the above solution, due to the rise of the detection needle assembly 8, when the round rod 89 encounters extrusion during the rising process, it can drive the rotating arm 88 and the movable cylinder 81 to rotate. At this time, the arc-shaped elastic member 65 is compressed. Due to the rotation of the movable cylinder 81, the inner detection needle 69 can be exposed from the inside of the movable cylinder 81.

[0047] like Fig. 9 and Fig.10 As shown, the outer side of the fixed sleeve 62 is connected to a square cylinder 610 on the same side as the rotating arm 88, and the inner movable sleeve of the square cylinder 610 is connected to a top block 611, one end of the top block 611 extends to the outer side of the square cylinder 610 and the port is semicircular, and the other end of the top block 611 is connected to a spring 612, and the other end of the spring 612 is connected to the square cylinder 610.

[0048] The above scheme is adopted: when the rotating arm 88 rotates vertically, the outer side of the clamping rod 810 will be squeezed with the top block 611 and push the top block 611 to move to the inner side of the square tube 610, so that the spring five 612 is compressed. When the rotating arm 88 rotates vertically, due to the elastic recovery effect of the spring five 612, the top block 611 will be pushed to be clamped and fixed inside the clamping rod 810, thereby fixing the vertical state of the rotating arm 88 and the horizontal state of the movable tube 81.

[0049] like Figure 6 , Fig.12 and Fig.13 As shown, it also includes a pressing mechanism 9, which is installed on the mounting frame 2. The pressing mechanism 9 includes a mounting block 91, which is installed on the mounting frame 2. An electromagnetic plate 92 is installed above the inside of the mounting block 91. The inside of the mounting block 91 is movably sleeved with a magnetic block 93 located below the electromagnetic plate 92. Moving rods 94 are connected to both sides below the magnetic block 93. The bottom end of the moving rod 94 extends to the bottom of the mounting block 91 and is connected to a pressing plate 97. The pressing plate 97 can abut against the round rod 89.

[0050] Adopt the above scheme: the control end turns on the electromagnetic plate 92, at this time the electromagnetic plate 92 will generate magnetic repulsion and push the magnetic block 93, the moving rod 94 and the lower pressure plate 97 to move downward, so that the round rod 89 can be blocked and squeezed by the lower pressure plate 97 during the rising process.

[0051] like Figure 6 , Fig.12 and Fig.13 As shown, a spring three 96 located on the inner side of the moving rod 94 is connected to the bottom of the magnetic block 93, and the other end of the spring three 96 is connected to the mounting block 91. A connecting plate 95 is connected to the bottom of the magnetic block 93, and the other side of the connecting plate 95 extends to the outside of the mounting block 91.

[0052] Adopt the above scheme: the control end opens the electromagnetic plate 92, at this time the electromagnetic plate 92 will generate a magnetic repulsion force and push the magnetic block 93, the moving rod 94 and the lower pressure plate 97 to move downward, at this time the spring three 96 is compressed, the control end will close the electromagnetic plate 92, due to the elastic recovery effect of the spring three 96, the magnetic block 93, the connecting plate 95, the moving rod 94 and the lower pressure plate 97 can be pushed to reset upward.

[0053] like Fig. 9 and Fig.10 As shown, it also includes an extrusion mechanism 10, which is installed on the mounting block 91. The extrusion mechanism 10 includes a double-way cylinder 101, which is installed on the mounting block 91. The double-way cylinder 101 is made of two cylinders connected to each other. A piston rod 105 is sleeved inside one of the cylinders of the double-way cylinder 101. The bottom end of the piston rod 105 is connected to a stop plate 106 located below the double-way cylinder 101, and the bottom of the stop plate 106 is in contact with the connecting plate 95.

[0054] By adopting the above scheme, due to the movement of the connecting plate 95, the abutment plate 106 and the piston rod 2 105 can be pushed upward, and the piston rod 1 102 and the inclined block 103 can be moved downward by air pressure. At this time, the tension spring 104 is stretched, so that the extrusion mechanism 10 can be operated through the connecting plate 95.

[0055] like Fig. 9 and Fig.10 As shown, a piston rod 102 is sleeved inside the other cylinder of the double-pass cylinder 101, a ramp block 103 is connected to the bottom end of the piston rod 102, a tension spring 104 is connected to the top end of the piston rod 102, and the other end of the tension spring 104 is connected to the double-pass cylinder 101.

[0056] The above scheme is adopted: the control end drives the electric telescopic rod 4 to drive the lifting frame 5 and the detection rod assembly 6 to move upward and reset. During the movement, the cone sleeve 811 can be abutted against the piston rod 102, and is squeezed by the inclined surface of the piston rod 102 and pushes the cone sleeve 811 and the clamping rod 810 to move toward the inside of the rotating arm 88. At the same time, the spring 2 812 is compressed, so that the clamping rod 810 is detached from the outside of the top block 611, thereby releasing the fixing effect of the rotating arm 88.

[0057] The working principle and use process of the present invention:

[0058] When in use, the transmission mechanism 1 transports the smart meter to the bottom of the detection needle assembly 8, and then the control end drives the electric telescopic rod 4 to operate, driving the lifting frame 5, the detection rod assembly 6 and the detection needle assembly 8 to move downward, and contacting the meter through the contact under the outer detection needle 82. The detection assembly 3 conducts the current through the detection assembly 3, the connecting line 7, the straight guide rod 63, the arc guide rod 64, and the inner detection needle 69 to the outer detection needle 82, and conducts the current to the smart meter through the outer detection needle 82 for detection.

[0059] When the current conduction is abnormal, the control end turns on the electromagnetic plate 92. At this time, the electromagnetic plate 92 will generate magnetic repulsion and push the magnetic block 93, the moving rod 94 and the lower pressure plate 97 to move downward. At this time, the spring three 96 is compressed. Due to the descent of the magnetic block 93, the connecting plate 95 can be moved downward. The tension spring 104, which is in a stretched state, can drive the piston rod 1 102 and the inclined block 103 to move upward due to the elastic recovery effect, and push the piston rod 2 105 and the abutment plate 106 to descend together with the connecting plate 95 through air pressure. The control end drives the electric telescopic rod 4 to drive the lifting frame 5, the detection rod assembly 6 and the detection needle assembly 8 to rise and reset. Due to the rise of the detection needle assembly 8, the round rod 89 can abut against the lower pressure plate 97 after the descent and be pressed downward. The plate 97 is squeezed, driving the rotating arm 88 and the movable cylinder 81 to rotate. At this time, the arc-shaped elastic member 65 is compressed. Due to the rotation of the movable cylinder 81, the insulating protrusion 85 can abut against the inner detection needle 69, and then the insulating protrusion 85 is squeezed and moved outward by the inner detection needle 69. At this time, the spring 87 is compressed, so that the inner detection needle 69 can pass through between the insulating protrusions 85 and emerge from the inside of the movable cylinder 81. After the detection rod assembly 6 rises and resets, the rotating arm 88 will rotate to vertical, and the movable cylinder 81 will rotate to horizontal. During the rotation of the movable cylinder 81, the outer detection needle 82 will pass through the wiping cotton 68, and the contact of the outer detection needle 82 will be wiped on the wiping cotton 68, so that the impurities on the contact of the outer detection needle 82 can be wiped off.

[0060] When the rotating arm 88 rotates vertically, the outer side of the clamping rod 810 will be pressed against the top block 611 and push the top block 611 to move to the inner side of the square tube 610, so that the spring 5 612 is compressed. When the rotating arm 88 rotates vertically, due to the elastic recovery effect of the spring 5 612, the top block 611 will be pushed to be clamped and fixed inside the clamping rod 810, thereby fixing the vertical state of the rotating arm 88 and the horizontal state of the movable tube 81. Then the control end continues to drive the electric telescopic rod 4 to drive the lifting frame 5 and the detection rod assembly 6 to move vertically. When the electric meter detects abnormalities, it can be determined that the external detection needle 82 has been repaired. This design allows the internal detection needle 69 to replace the external detection needle 82 in the event of poor contact of the external detection needle 82, thereby improving the measurement accuracy of the electric meter parameters and avoiding the problem of misjudgment of electric meter defects.

[0061] When the inner detection needle 69 has finished detecting the electric meter, the control end will close the electromagnetic plate 92. At this time, due to the elastic recovery effect of the spring three 96, the magnetic block 93, the connecting plate 95, the moving rod 94 and the lower pressure plate 97 can be pushed to reset upward. Due to the movement of the connecting plate 95, the abutment plate 106 and the piston rod two 105 can be pushed to move upward, and the piston rod one 102 and the inclined surface block 103 can be squeezed downward by air pressure. At this time, the tension spring 104 is stretched, and then the control end drives the electric telescopic rod 4 to drive the lifting frame 5 and the detection rod assembly 6 to move upward and reset. During the movement, the cone sleeve 811 can be abutted against the piston rod one 102, and the cone sleeve 811 and the card can be squeezed by the inclined surface of the piston rod one 102 and pushed. The rod 810 moves toward the inside of the rotating arm 88, and the spring 2 812 is compressed, so that the locking rod 810 is disengaged from the outside of the top block 611, thereby releasing the fixing effect of the rotating arm 88. Due to the elastic recovery effect of the arc-shaped elastic member 65, the movable cylinder 81 and the rotating arm 88 can be pushed to rotate and reset, and the inner detection needle 69 can be stored in the inside of the movable cylinder 81 again and abut against the outer detection needle 82. During the resetting process of the movable cylinder 81, the inner detection needle 69 will pass through the wiping cotton 2 84 and wipe on the wiping cotton 2 84 to prevent the contact of the inner detection needle 69 from being contaminated with dust and impurities. At the same time, the resetting of the movable cylinder 81 allows the device to continue to use the outer detection needle 82 for detection operations.
