[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0034] The embodiments provided by the present application include:

[0035] Embodiment one:

[0036] Please refer to Figure 1 As shown in the figure, a smart voltage meter for power distribution system includes a distribution box door 11 and a voltmeter 12. The voltmeter 12 is clamped on the distribution box door 11. Specifically, a rectangular slot is formed in the middle of the distribution box door 11, and the voltmeter 12 is clamped in the rectangular slot. The voltmeter 12 is provided with a pointer 13, and two wires 14 are symmetrically installed on the side of the voltmeter 12 away from the pointer 13.

[0037] In the prior art, the two wires 14 are inserted into the bolt terminal of the voltmeter 12 through the wire clamp, and then the bolt on the bolt terminal of the wire clamp is rotated to tightly attach the two wires 14 and the wire clamp to the voltmeter 12.

[0038] The ends of the two wires 14 away from the voltmeter 12 are connected to the inside of the power distribution cabinet.

[0039] The voltmeter 12 is provided with a protective cover made of transparent acrylic material on the side close to the pointer 13, which is not shown in the figure.

[0040] The voltmeter 12 measures the voltage inside the power distribution cabinet through the two wires 14, which is a known technology, and will not be described here.

[0041] Wherein: the end of the pointer 13 connected with the voltmeter 12 is the fixed end, and the end of the pointer 13 away from the fixed end is the indicating end.

[0042] Wherein: the voltmeter 12 is provided with a scale indicating voltage, and the scale is arranged in a quarter annular shape, and the reference Figure 1 At this time, the end indicated by the indicating end of the pointer 13 is the zero scale end.

[0043] Wherein: in use, the voltmeter 12 measures the voltage inside the power distribution cabinet through two wires 14, and indicates the direction of the scale through the deflection of the pointer 13 to display the voltage, that is, the staff can observe the position of the indicating end of the pointer 13 on the scale to obtain the voltage measured by the voltmeter 12.

[0044] Please refer to Figures 1 to 8 As shown in the figure, the voltmeter 12 is provided with a quick disassembly and assembly assembly, the quick disassembly and assembly assembly includes four pulleys 21, the four pulleys 21 are rotationally connected in a rectangular array on the side of the voltmeter 12 close to the pointer 13, and a belt 22 is transmissionally connected between the four pulleys 21, one end of one of the pulleys 21 away from the voltmeter 12 is fixedly connected with a gear one 23, a limiting block 24 is fixedly connected on the inner side wall of the voltmeter 12, a rack 25 is slidingly connected on the limiting block 24, a fixed block 26 is fixedly connected on the inner side wall of the voltmeter 12 below the limiting block 24, a guide rod 27 is slidingly connected on the fixed block 26, the top end of the guide rod 27 is fixedly connected with the bottom end of the rack 25, a spring one 28 is sleeved on the guide rod 27, and the two ends of the spring one 28 are fixedly connected with the rack 25 and the fixed block 26 respectively, four toothed plates 29 are fixedly connected in a rectangular array on the belt 22, and four rotating shafts 210 are rotationally connected in a rectangular array on the voltmeter 12, the two ends of the rotating shaft 210 both pass through the voltmeter 12, a gear two 211 is fixedly connected on the end of the rotating shaft 210 close to the toothed plate 29, and a clamping plate 212 is fixedly connected on the end of the rotating shaft 210 away from the gear two 211.

[0045] Wherein: the gear one 23 and the rack 25 are meshed with each other, the rack 25 passes through the top of the voltmeter 12, and the toothed plate 29 and the gear two 211 are meshed with each other.

[0046] Wherein: in the initial stage, that is, when the voltmeter 12 is installed on the power distribution box door 11, the bottom end of the rack 25 is meshed with the gear one 23, the spring one 28 is not elastically compressed, the four clamping plates 212 abut against the power distribution box door 11, and the voltmeter 12 is fixed on the power distribution box door 11 by the four clamping plates 212.

[0047] In use of the quick disassembly and assembly assembly, the staff presses the rack 25 downward, so that the rack 25 slides downward on the limiting block 24, at this time, the spring one 28 is elastically compressed, the four clamping plates 212 are separated from the power distribution box door 11, and the voltmeter 12 can be taken off the power distribution box door 11. Figure 1For position reference, when the rack 25 moves downward, the rack 25 drives the gear one 23 to rotate counterclockwise, the gear one 23 drives the pulley 21 connected thereto to rotate counterclockwise synchronously, and then the remaining three pulleys 21 are driven by the belt 22 to rotate counterclockwise synchronously. At this time, the belt 22 drives the four toothed plates 29 to move synchronously while the belt 22 drives counterclockwise, and then the four toothed plates 29 drive the four gear twos 211 to rotate while moving, the gear twos 211 drive the shaft 210 to rotate synchronously, at this time, with the rotation of the shaft 210, the four clamping plates 212 rotate synchronously, as shown in Figure 2 , the four clamping plates 212 rotate counterclockwise with the corresponding shaft 210 as the axis, so that the clamping plates 212 gradually rotate to be close to the voltmeter 12, at this time, the four clamping plates 212 no longer abut against the distribution box door 11, and then the staff can directly pull out the voltmeter 12 from the rectangular slot in the middle of the distribution box door 11 while pressing the rack 25, at this time, the voltmeter 12 is quickly disassembled.

[0048] When it is needed to quickly install the voltmeter 12 on the distribution box door 11, the staff inserts the voltmeter 12 into the rectangular slot in the middle of the distribution box door 11 while pressing the rack 25, until the side of the voltmeter 12 close to the pointer 13 abuts against the distribution box door 11, for details, please refer to Figure 7 , the one side of the voltmeter 12 is larger than the rectangular slot in the middle of the distribution box door 11, so the voltmeter 12 can abut against the distribution box door 11, then the rack 25 is no longer pressed, at this time, the rack 25 slides upward under the elastic extension of the spring one 28, and then the rack 25 drives the gear one 23 to rotate reversely, the pulley 21, the belt 22, the shaft 210, the gear two 211, the clamping plate 212 and other structures all move reversely as described above, for details, please refer to the above description, the four clamping plates 212 rotate reversely, so that the four clamping plates 212 abut against the distribution box door 11, so that the voltmeter 12 is fixed on the distribution box door 11 by the four clamping plates 212, at this time, the voltmeter 12 is quickly installed.

[0049] In the above process, the voltmeter 12 is quickly disassembled and installed by the operation of the quick disassembly and assembly assembly, so that the staff can disassemble the faulty voltmeter 12 and install a new voltmeter 12 in a very short time, compared with the traditional way of spending a lot of time to disassemble screws, loosen nuts and other operations, the quick disassembly and assembly greatly saves the time of replacing the voltmeter 12, thereby reducing the stagnation time of the voltmeter 12 caused by maintenance and replacement.

[0050] Embodiment two:

[0051] In the prior art, when the worker uses the voltmeter 12, the worker must first perform a zero adjustment operation to ensure that the pointer 13 accurately points to the zero scale line, and if the zero adjustment operation is not performed, the measurement result of the voltmeter 12 will be erroneous, and the worker needs to check the stability of the connection of the electric wire 14 and the voltmeter 12. In the traditional way, the zeroing of the pointer 13 and the checking of the stable circuit are two independent steps, which need to be operated by the worker in sequence, thereby increasing the complexity of the operation and the required time.

[0052] Referring to Figures 1 to 4 and Figures 8 to 10 to solve the above-mentioned problems, a pre-use preparation assembly is further provided on the voltmeter 12. The pre-use preparation assembly includes a guide groove 31, which is provided on the voltmeter 12. The voltmeter 12 is fixedly connected with a servo motor 32 on the side close to the electric wire 14. The output shaft of the servo motor 32 is close to the voltmeter 12, and there is a gap between the output shaft of the servo motor 32 and the voltmeter 12. The output shaft of the servo motor 32 is fixedly connected with a connecting rod 33. The connecting rod 33 is fixedly connected with a sliding rod 34 at the end away from the output shaft of the servo motor 32. The sliding rod 34 is fixedly connected with a rubber push block one 35 at the end away from the connecting rod 33. The voltmeter 12 is provided with a straight groove 36 on the side close to the servo motor 32. The straight groove 36 is slidably connected with a push plate 37. The push plate 37 is fixedly connected with a spring two 38 at the bottom end away from the electric wire 14. The spring two 38 is fixedly connected with the voltmeter 12 at the end away from the straight groove 36. Two electric wires 14 are fixedly connected with a connecting plate 39. The voltmeter 12 is slidably connected with an inclined lifting plate 310 on the side close to the electric wire 14. The inclined lifting plate 310 is fixedly connected with a spring three 311 at the bottom end close to the electric wire 14. The inclined lifting plate 310 is fixedly connected with a rubber push block two 312 at the top end close to the electric wire 14.

[0053] Among them: the guide groove 31 is set as a semicircle with the fixed end of the pointer 13 as the center, and the guide groove 31 is located on the moving path of the pointer 13.

[0054] Among them: in the prior art, the voltmeter 12 is provided with a stop column for stopping the rotation of the pointer 13 at the position of the zero scale line of the scale.

[0055] Among them: the sliding rod 34 is slidably connected with the guide groove 31, and the pointer 13 is located on the moving path of the rubber push block one 35.

[0056] Among them: the bottom end of the spring three 311 is fixedly connected with the voltmeter 12.

[0057] Among them: the end close to the push plate 37 of the inclined lifting plate 310 is set as an inclined surface, the top surface of the push plate 37 is set as an inclined surface, the inclined surface of the push plate 37 is in extrusion fit with the inclined surface of the inclined lifting plate 310, and the inclined lifting plate 310 is vertically limitedly and slidably connected with the voltmeter 12.

[0058] The connecting plate 39 is located on the moving path of the rubber push block two 312, and the connecting plate 39 is in contact with the rubber push block two 312.

[0059] The servo motor 32 has an electrical connection relationship with the external controller, and when the servo motor 32 is started, the output shaft thereof rotates counterclockwise by one hundred and eighty degrees, and then reversely rotates to reset.

[0060] The push plate 37 is limited to slide inside the straight slot 36, so that the push plate 37 can only move horizontally.

[0061] The output shaft of the servo motor 32 and the fixed end of the pointer 13 are located at the same coaxial position.

[0062] In the initial state, i.e. when the staff does not use the voltmeter 12 to observe the voltage, the rubber push block one 35 is located at one end away from the rack 25 inside the guide slot 31, the spring two 38 does not produce elastic deformation, and the spring three 311 does not produce elastic deformation.

[0063] When the voltmeter 12 is used, before the staff uses the voltmeter 12 to observe the voltage, at this time the voltmeter 12 is in a power-off state, i.e. the pointer 13 of the voltmeter 12 needs to be zeroed and the connection of the power cord 14 needs to be stable, at this time the staff controls the servo motor 32 to start through the external controller, the servo motor 32 starts to drive the slide rod 34 to rotate counterclockwise by one hundred and eighty degrees, i.e. the slide rod 34 slides to the end close to the rack 25 inside the guide slot 31, in this process, the slide rod 34 drives the rubber push block one 35 to move synchronously, while the rubber push block one 35 moves, it touches the pointer 13, so that the pointer 13 rotates to the direction of the stop post, when the pointer 13 touches the stop post, i.e. the pointer 13 rotates to the zero position of the voltmeter 12, at this time the output shaft of the servo motor 32 rotates to reset.

[0064] Because the bolt terminal will loosen during use, the wire clamp of the power cord 14 no longer fits the voltmeter 12, so the wire clamp will loosen downward, and in the process of rotating the slide rod 34, the slide rod 34 will push the push plate 37 to the power cord 14, and at the same time the push plate 37 slides to the power cord 14 inside the straight slot 36, the spring two 38 is elastically stretched, in the process of moving the push plate 37, the push plate 37 touches and presses the inclined lifting plate 310, so that the inclined lifting plate 310 moves upward on the voltmeter 12, and at the same time the spring three 311 is elastically stretched, in the process of lifting the inclined lifting plate 310, the inclined lifting plate 310 pushes the connecting plate 39 to lift through the rubber push block two 312, and the rubber push block two 312 produces elastic deformation, so that the connecting plate 39 drives the two power cords 14 to be pushed tightly to the terminal of the voltmeter 12.

[0065] In the process of rotating the slide rod 34 to reset, at this time the slide rod 34 no longer applies a pushing force to the slide rod 34 to the side of the wire 14, under the elastic contraction of the spring two 38, the spring two 38 pulls the push plate 37 to reset, when the push plate 37 resets to no longer resist the inclined lifting plate 310, at the same time the rubber push block two 312 elastically expands, and the spring three 311 elastically contracts to reset, pulling the inclined lifting plate 310 to reset.

[0066] In the process of operating the pre-use preparation assembly, by means of the rubber push block one 35, the pointer 13 is pushed to the zero position, which can eliminate the initial error before each use of the voltmeter 12, and ensure the accuracy of the voltage measurement result of the voltmeter 12, at the same time, since the stroke of the rubber push block one 35 is fixed each time, that is, the operation of zeroing the pointer 13 each time is uniform, so as to ensure the repeatability of the zeroing operation of the pointer 13 by the pre-use preparation assembly and the reliability of the zeroing effect.

[0067] By means of the rubber push block two 312, the wire 14 is tightly pushed and fastened to the direction of the terminal of the voltmeter 12, which ensures the close and reliable connection between the wire 14 and the voltmeter 12, reduces the risk of poor contact, and guarantees the accuracy of the voltage detection of the voltmeter 12, and the rubber material of the rubber push block two 312 provides a flexible pushing force for the wire 14, which can avoid damage to the wire 14 caused by excessive pushing force.
