[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiments provided by the present invention:

[0035] Embodiment 1:

[0036] See also Figure 1 As shown, a voltmeter for an intelligent power distribution system includes a distribution box door 11 and a voltmeter 12. The voltmeter 12 is snapped onto the distribution box door 11. Specifically, a rectangular groove is opened in the middle of the distribution box door 11, and the voltmeter 12 is snapped into the rectangular groove. A pointer 13 is installed on the voltmeter 12, and two wires 14 are symmetrically installed on the side of the voltmeter 12 away from the pointer 13.

[0037] Among them: In the prior art, the two wires 14 are plugged into the bolt terminal on the voltmeter 12 through the wiring clamp, and then the bolt on the bolt terminal is rotated so that the two wires 14 and the wiring clamp fit tightly on the voltmeter 12.

[0038] Wherein: one end of the two wires 14 away from the voltmeter 12 is connected to the inside of the power distribution cabinet.

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

[0040] Among them: the voltmeter 12 measures the internal voltage of the distribution cabinet through two wires 14, which is a known technology and will not be described in detail here.

[0041] Among them: the end of the pointer 13 connected to 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 the voltage, and the scale is arranged in a quarter ring shape, referring to Figure 1 At this time, the end pointed by the pointer 13 is the zero scale end.

[0043] Among them: when in use, the voltmeter 12 measures the voltage inside the distribution cabinet through two wires 14, and displays the voltage in the direction of the deflection indication scale of the pointer 13, 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] See also Figures 1 to 8 As shown, the voltmeter 12 is provided with a quick disassembly assembly, which includes four pulleys 21, which are rotatably connected to the side of the voltmeter 12 close to the pointer 13 in a rectangular array, and a belt 22 is commonly connected to the four pulleys 21 for transmission, and a gear 23 is fixedly connected to the end of one of the pulleys 21 away from the voltmeter 12, a limit block 24 is fixedly connected to the inner wall of the voltmeter 12, and a rack 25 is slidably connected to the limit block 24, and a fixed block 26 is fixedly connected to the inner wall of the voltmeter 12 and located below the limit block 24, and a fixed block 26 is slidably connected to the fixed block 26. A guide rod 27 is movably connected, the top of the guide rod 27 is fixedly connected to the bottom of the rack 25, a spring 28 is sleeved on the guide rod 27, the two ends of the spring 28 are respectively fixedly connected to the rack 25 and the fixed block 26, four tooth plates 29 are fixedly connected to the belt 22 in a rectangular array, four rotating shafts 210 are rotatably connected to the voltmeter 12 in a rectangular array, both ends of the four rotating shafts 210 pass through the voltmeter 12, one end of the rotating shaft 210 close to the tooth plate 29 is fixedly connected to a gear 211, and the end of the rotating shaft 210 away from the gear 211 is fixedly connected to a clamping plate 212.

[0045] Among them: gear 1 23 and rack 25 are meshed with each other, rack 25 passes through the top of voltmeter 12, and toothed plate 29 and gear 2 211 are meshed with each other.

[0046] Among them: in the initial stage, that is, when the voltmeter 12 is installed on the distribution box door 11, the bottom end of the rack 25 is engaged with the gear 1 23, the spring 1 28 is not elastically compressed, the four clamping plates 212 are in contact with the distribution box door 11, and the voltmeter 12 is fixed on the distribution box door 11 by the four clamping plates 212.

[0047] When the quick disassembly assembly is used, the staff presses the rack 25 downward so that the rack 25 slides downward on the limit block 24. Figure 1Taking this as the position reference, while the rack 25 moves downward, the rack 25 drives the first gear 23 to rotate counterclockwise. The first gear 23 drives the pulley 21 connected thereto to rotate synchronously counterclockwise. Furthermore, the other three pulleys 21 are driven by the belt 22 to rotate synchronously counterclockwise. At this time, the belt 22 is driven to rotate counterclockwise. While the belt 22 is driven to rotate counterclockwise, the belt 22 drives the four toothed plates 29 to move synchronously. Furthermore, while the four toothed plates 29 move, they mesh and drive the four second gears 211 to rotate. The rotation of the second gears 211 drives the rotating shafts 210 to rotate synchronously. At this time, with the rotation of the rotating shafts 210, referring to Figure 2 as shown, the rotating shafts 210 drive the clamping plates 212 to rotate synchronously. At this time, the four clamping plates 212 rotate counterclockwise with the corresponding rotating shafts 210 as the axes, 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. Furthermore, the staff can directly pull out the voltmeter 12 from the rectangular slot in the middle of the distribution box door 11 while keeping pressing the rack 25. At this time, the rapid removal of the voltmeter 12 is completed.

[0048] When the voltmeter 12 needs to be quickly installed on the distribution box door 11, the staff, while keeping pressing the rack 25, plug the voltmeter 12 into the rectangular slot in the middle of the distribution box door 11 until the side of the voltmeter 12 close to the pointer 13 abuts against the distribution box door 11. For details, reference can be made to Figure 7 , the size of one side of the voltmeter 12 is larger than the rectangular slot in the middle of the distribution box door 11. Therefore, the voltmeter 12 can abut against the distribution box door 11. Then, stop pressing the rack 25. At this time, under the elastic stretching action of the first spring 28, the rack 25 is pushed to slide upward. Furthermore, at this time, the rack 25 drives the first gear 23 to rotate in the reverse direction. Structures such as the pulleys 21, the belt 22, the rotating shafts 210, the second gears 211, and the clamping plates 212 all move in the reverse direction as described in the above text. Specifically: the four clamping plates 212 rotate in the reverse direction, so that the four clamping plates 212 abut against and fit with 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 rapid installation of the voltmeter 12 is completed.

[0049] In the above process, through the operation of the quick disassembly and assembly component, the quick disassembly and assembly of the voltmeter 12 are realized. The staff can remove the faulty voltmeter 12 and install a new voltmeter 12 in a very short time. Compared with the traditional method that requires a lot of time to remove screws, loosen nuts, etc., the quick disassembly and assembly greatly save the time for replacing the voltmeter 12, thereby reducing the stagnant time of the voltmeter 12 for detecting voltage caused by maintenance and replacement.

[0050] Embodiment 2:

[0051] In the prior art, when a worker uses the voltmeter 12, he must first perform a zero adjustment operation to ensure that the indicating end of the pointer 13 accurately points to the zero scale line. If the zero adjustment operation is not performed, the measurement result of the voltmeter 12 will produce an error. At the same time, the worker needs to check the connection between the wire 14 and the voltmeter 12 for stability. Under the traditional method, zeroing the pointer 13 and checking the stability of the line are two independent steps, which require the worker to perform the operations in sequence, increasing the complexity and time required for the operation.

[0052] Reference Figures 1 to 4 and Figures 8 to 10 As shown, in order to solve the above-mentioned problems, a useful preparatory component is further provided on the voltmeter 12, and the useful preparatory component includes a guide groove 31, and the guide groove 31 is opened on the voltmeter 12, and a servo motor 32 is fixedly connected to the side of the voltmeter 12 close to the wire 14, and the output shaft of the servo motor 32 is close to the side of the voltmeter 12, and there is a gap between the output shaft of the servo motor 32 and the voltmeter 12, and a connecting rod 33 is fixedly connected to the output shaft of the servo motor 32, and a sliding rod 34 is fixedly connected to the end of the connecting rod 33 away from the output shaft of the servo motor 32, and a rubber push block is fixedly connected to the end of the sliding rod 34 away from the connecting rod 33. 35. A linear groove 36 is provided on the side of the voltmeter 12 close to the servo motor 32, a push plate 37 is slidably connected inside the linear groove 36, a spring 2 38 is fixedly connected to the bottom end of the push plate 37 on the side away from the wire 14, one end of the spring 2 38 away from the linear groove 36 is fixedly connected to the voltmeter 12, a connecting plate 39 is fixedly connected to both wires 14, an inclined lifting plate 310 is slidably connected to the side of the voltmeter 12 close to the wire 14, a spring 311 is fixedly connected to the bottom end of the inclined lifting plate 310 on the side close to the wire 14, and a rubber push block 2 312 is fixedly connected to the top of the inclined lifting plate 310 on the side close to the wire 14.

[0053] The guide groove 31 is configured as a semi-circular shape 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, a stop post for stopping the pointer 13 from rotating is provided at the zero scale line position on the voltmeter 12.

[0055] The slide bar 34 is slidably connected to the guide groove 31 , and the pointer 13 is located on the moving path of the rubber push block 1 35 .

[0056] Wherein: the bottom end of spring three 311 is fixedly connected to voltmeter 12.

[0057] Among them: the end of the inclined lifting plate 310 close to the push plate 37 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 squeezed and matched with the inclined surface of the inclined lifting plate 310, and the inclined lifting plate 310 is vertically limited and slidably connected with the voltmeter 12.

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

[0059] The servo motor 32 is electrically connected to the external controller. When the servo motor 32 is started, its output shaft rotates 180 degrees counterclockwise, and then rotates in the reverse direction to reset.

[0060] The push plate 37 is limited in sliding movement inside the linear groove 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 coaxially located.

[0062] Among them: in the initial state, that is, when the staff does not use the voltmeter 12 to observe the voltage, the rubber push block 1 35 is located at the end of the guide groove 31 away from the rack 25, the spring 2 38 does not produce elastic deformation, and the spring 3 311 does not produce elastic deformation.

[0063] When the pre-use preparation component is used, before the staff uses the voltmeter 12 to observe the voltage, the voltmeter 12 is in a power-off state, that is, the pointer 13 of the voltmeter 12 needs to be zeroed and the wire 14 needs to be firmly connected. At this time, the staff controls the servo motor 32 to start through the external controller. The servo motor 32 starts and drives the slide bar 34 to rotate one hundred and eighty degrees counterclockwise through the connecting rod 33, that is, the slide bar 34 slides inside the guide groove 31 to the end close to the rack 25. During this process, the slide bar 34 drives the rubber push block 35 to move synchronously. While the rubber push block 35 moves, it contacts the pointer 13, causing the pointer 13 to rotate toward the stop column. When the pointer 13 contacts the stop column, that is, the pointer 13 rotates to the zero position of the voltmeter 12, and the output shaft of the servo motor 32 rotates to reset.

[0064] Because the bolt terminal will loosen during use, the terminal clamp of the wire 14 will no longer fit with the voltmeter 12, so the terminal clamp will loosen downward, and during the rotation of the slide bar 34, the slide bar 34 will push the push plate 37 in the direction of the wire 14, and at the same time, the push plate 37 slides in the direction of the wire 14 inside the linear groove 36, and the spring 2 38 is elastically stretched. During the movement of the push plate 37, the push plate 37 resists and squeezes 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 311 is elastically stretched. During the lifting of the inclined lifting plate 310, the inclined lifting plate 310 pushes the connecting plate 39 to lift through the rubber push block 2 312, and the rubber push block 2 312 produces elastic deformation, so that the connecting plate 39 drives the two wires 14 to be pushed tightly in the direction of the terminal of the voltmeter 12.

[0065] When the slide bar 34 rotates to reset, the slide bar 34 no longer applies a thrust to the side of the wire 14. Under the elastic contraction of the spring 2 38, the spring 2 38 pulls the push plate 37 to reset. When the push plate 37 is reset to the point where it no longer conflicts with the inclined lifting plate 310, the rubber push block 2 312 elastically stretches, and the spring 311 elastically contracts and resets, pulling the inclined lifting plate 310 to reset.

[0066] During the operation of the pre-use preparation component, the pointer 13 is moved to the zero position by the rubber push block 35, so that the initial error can be eliminated before each use of the voltmeter 12, thereby ensuring the accuracy of the voltage measurement result of the voltmeter 12. At the same time, since the stroke of the rubber push block 35 is fixed each time, that is, the operation of returning the pointer 13 to zero each time is unified, the repeatability of the pre-use preparation component for returning the pointer 13 to zero and the reliability of the zeroing effect can be ensured.

[0067] The rubber push block 2 312 is used to push and tighten the wire 14 toward the terminal of the voltmeter 12, ensuring a tight and reliable connection between the wire 14 and the voltmeter 12, reducing the risk of poor contact and ensuring the accuracy of the voltage detected by the voltmeter 12. The rubber material of the rubber push block 2 312 provides a flexible thrust for tightening the wire 14, thereby preventing the wire 14 from being damaged by excessive thrust.
