DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, it shows a perspective structural diagram of an electric meter circuit detection and calibration device provided by the invention; Figures 2 to 6 As shown, in this embodiment, the meter line detection and calibration device is provided with a conveyor belt 1, and a fixed plate 2 is installed at an equal distance above the conveyor belt 1; a signal light alarm mechanism, a signal alarm light 5 is arranged above the fixed plate 2, and once the meter body 3 is connected to the power supply, the signal alarm light 5 can flash to detect and judge the meter body 3; a clamping and fixing mechanism is arranged at the output end of the hydraulic rod 14, and the output end of the hydraulic rod 14 can push it to move downward, so that the clamping block 9 is located on the left and right sides of the outside of the meter body 3, and the clamping block 9 can firmly clamp and fix the meter body 3; an anti-falling mechanism is arranged on the power line 17 is on the outside to ensure that the power cord 17 will not fall off when connected to the interface 20; first, open the conveyor belt 1 so that the conveyor belt 1 transmits to the fixed plate 2. Since the electric meter body 3, the sensor 4 and the signal alarm light 5 are arranged above the fixed plate 2, the electric meter body 3, the sensor 4 and the signal alarm light 5 are connected by the connecting line 6. When the electric meter body 3 is transmitted to the middle of the conveyor belt 1, open the hydraulic rod 14 arranged on the lower side above the support frame 15 installed at the rear of the middle of the conveyor belt 1, so that the output end of the hydraulic rod 14 pushes the fixed clamping mechanism connected below to move downward, so that the clamping block 9 is symmetrical on the left and right. Located on the outside of the meter body 3, the electric telescopic rod 13 is opened, and the output end of the electric telescopic rod 13 can make the connected connecting rod 12 move upward on the fixed frame 7. When the connecting rod 12 moves, the rotating rod 11 connected to the outside of the connecting rod 12 will rotate, that is, the gear 10 connected to the rotating rod 11 will also rotate inside the fixed frame 7. When the gear 10 rotates, it will push the meshing rack block 8 to move inward. Since the clamping block 9 is fixedly installed below the rack block 8, the clamping block 9 will also move inward to clamp and fix the meter body 3, and then open the electric telescopic rod 13 connected to the rear side of the fixed block 16. A power cord 17 is set in the middle of the fixed block 16, and the outer side of the power cord 17 is tightly fitted with a limit plate 18. A spring 19 is set on the outer side of the limit plate 18 for support and fixation, that is, the output end of the electric telescopic rod 13 will push the power cord 17 inside the fixed block 16 to engage with the interface 20 opened at the rear of the front electric meter body 3. At this time, the electric meter body 3 is connected to the power supply, and the sensor 4 is installed between the electric meter body 3 and the signal alarm light 5. If the internal circuit of the electric meter body 3 is normal, the signal alarm light 5 will light up green. Once the internal circuit of the electric meter body 3 is abnormal, the signal alarm light 5 will light up red and an alarm will be sounded.

[0034] In the existing meter circuit detection and calibration device, during the circuit calibration process, once the meter body 3 is offset, the power line 17 and the meter body 3 cannot be connected for calibration. Figure 1 , Figure 2and Figure 3 As shown, the clamping and fixing mechanism includes an electric telescopic rod 13 arranged at the output end of the hydraulic rod 14. The hydraulic rod 14 is first opened, so that the output end of the hydraulic rod 14 pushes the clamping and fixing mechanism to move downward, so that the clamping block 9 is symmetrically located on the outside of the electric meter body 3. Since the output end of the electric telescopic rod 13 is connected to the connecting rod 12, the connecting rod 12 is located inside the fixing frame 7. Then the electric telescopic rod 13 is opened, and the output end of the electric telescopic rod 13 can drive the connecting rod 12 to move upward. At this time, the rotating rod 11 symmetrically connected to the left and right sides of the connecting rod 12 will rotate, that is, the gear 10 connected to the rotating rod 11 will also rotate. Since the rack block 8 is meshed and connected at the bottom of the gear 10, when the gear 10 rotates, the rack block 8 will move inward inside the fixing frame 7. At the same time, the clamping block 9 is fixedly connected to the bottom of the rack block 8, that is, the clamping block 9 will also move inward, and will firmly clamp and fix the inner electric meter body 3.

[0035] In the existing device, when the power cord 17 is connected to the meter body 3, once a problem is found in the calibration, it is impossible to quickly remind the operator. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 , Figure 5 and Figure 6 As shown, the signal light alarm mechanism includes an electric meter body 3 arranged above the fixed plate 2, and a sensor 4 and a signal alarm light 5 are arranged on the front side of the electric meter body 3. The signal alarm light 5 is located on the front side of the sensor 4. In addition, the electric meter body 3, the sensor 4 and the signal alarm light 5 are connected by a connecting line 6. Secondly, an interface 20 is provided on the inner rear side of the electric meter body 3. When the power line 17 is connected to the interface 20 and the power is turned on, it can be known whether the electric meter body 3 can operate normally. Since the signal alarm light 5 is connected to the front side of the electric meter body 3 through the sensor 4, if the electric meter body 3 is normal, the signal alarm light 5 will light up green, and if the electric meter body 3 is abnormal, the signal alarm light 5 will light up red and an alarm will sound, which can help operating staff quickly screen out problematic electric meter bodies 3.

[0036] In the existing device, the hydraulic rod 14 may fall off when connected to the electric telescopic rod 13. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 4 As shown, the anti-falling mechanism includes a limiting plate 18 symmetrically arranged on the outside of the power cord 17, a spring 19 is arranged on the outside of the limiting plate 18, and a fixing block 16 is fixedly connected to the outside of the spring 19, that is, the limiting plate 18 can support and fix the power cord 17, and can ensure that the power cord 17 will not fall off when connected to the interface 20. At the same time, the bottom of the limiting plate 18 can slide on the inside of the fixing block 16, which is convenient for disassembly of the power cord 17.

[0039] In the embodiment of the present invention, a fixing plate and an electric meter body are provided.

Since the sensor and the signal alarm light are connected to the front side of the electric meter body by connecting lines, if the electric meter body is normal, the signal alarm light will light up green through the sensor. If the electric meter body is abnormal, the signal alarm light will light up red and an alarm will sound, which can help operating staff quickly screen out problematic electric meter bodies.

[0041] In addition, a fixing frame, a rack block, a clamping block and a gear are provided.

The output end of the electric telescopic rod can drive the connecting rod to move upward. At this time, the rotating rods symmetrically connected on the left and right sides of the connecting rod will rotate, that is, the gear connected to the rotating rod will also rotate. Since the rack block is meshed and connected at the bottom of the gear, when the gear rotates, the rack block will move inward inside the fixing frame. At the same time, the clamping block is fixedly connected at the bottom of the rack block, that is, the clamping block will also move inward, and will firmly clamp and fix the electric meter body inside.

[0042] Furthermore, a fixing block, a power cord and an interface are provided, the fixing block is fixedly connected through the output end of the electric telescopic rod, a power cord is provided in the middle of the fixing block, so that the power cord is connected to the interface opened at the rear side of the electric meter body, to provide power for the electric meter body, and the electric meter body can be quickly calibrated and tested;
