DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs. The "first", "second" and similar words used in one or more embodiments of this specification do not indicate any order, quantity or importance, but are only used to distinguish different components.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] Based on the above objectives, the first aspect of the present invention provides an implementation of a switching device for replacing an electric meter without power failure, such as Figure 1 As shown, including:

[0034] A meter box 1, a first electric meter 2 fixed in the meter box 1, an incoming line 3 connected to an incoming terminal of the first electric meter 2, and an outgoing line 4 connected to an outgoing terminal of the first electric meter 2;

[0035] A first switch 5 installed on the incoming line 3 and a second switch 6 installed on the outgoing line 4, wherein the first switch 5 is used to control the on and off of the incoming line 3, and the second switch 6 is used to control the channel of the outgoing line 4;

[0036] A connecting line 7 connecting the incoming line 3 and the outgoing line 4 and a third switch 8 installed on the connecting line 7, the third switch 8 is used to control the on and off of the connecting line 7, the first switch 5 is located between the connection between the connecting line 7 and the incoming line 3 and the incoming end of the first electric meter 2, and the second switch 6 is located between the connection between the connecting line 7 and the outgoing line 4 and the outgoing end of the first electric meter 2.

[0037] In this embodiment, when the first electric meter 2 is operating normally, the third switch 8 is in the disconnected state, and the first switch 5 and the second switch 6 are in the connected state. When the first electric meter 2 needs to be replaced, the third switch 8 is first switched to the connected state, and then the first switch 5 and the second switch 6 are both switched to the disconnected state. At this time, the first electric meter 2 can be replaced. During the process of replacing the first electric meter 2, the normal electricity consumption of the user will not be affected. After the first electric meter 2 is replaced, the first switch 5 and the second switch 6 are first switched to the connected state, and then the third switch 8 is switched to the disconnected state to achieve uninterrupted power switching.

[0038] Considering that the user is still using electricity during the process of replacing the meter, the electricity consumption at this time cannot be counted. To overcome this problem, as an implementation method, Figure 2 As shown, it includes a second electric meter 9, and the connecting line 7 includes a connecting incoming line 71 and a connecting outgoing line 72. The connecting incoming line 71 connects the incoming line 3 and the incoming end of the second electric meter 9, and the connecting outgoing line 72 connects the outgoing line 4 and the outgoing end of the second electric meter 9. The third switch 8 is installed on the connecting incoming line 71. In this way, during the process of replacing the first electric meter 2, the second electric meter 9 is used to count the user's electricity consumption.

[0039] Considering that the cost of installing a second electric meter 9 in each meter box 1 is too high, in order to save costs, as an implementation method, Figure 3 and Figure 4 As shown, it also includes:

[0040] Conductive block 11, the end of the connecting line 71 for connecting to the third meter inlet and the end of the connecting line 72 for connecting to the third meter outlet are both fixed with the conductive block 11, and the conductive block 11 is fixed to the inner wall of the meter box 1;

[0041] A fixing plate 10 fixed to the front end of the third electric meter, wherein the front end surface of the fixing plate 10 is provided with a placement groove 12 corresponding to the conductive block 11;

[0042] A conductive spring piece 23 is arranged on the side of the placement slot 12, wherein the conductive spring piece 23 corresponding to the connection incoming line 71 is connected to the inlet end of the third electric meter, and the conductive spring piece 23 corresponding to the connection outgoing line 72 is connected to the outlet end of the third electric meter;

[0043] The drive is arranged in the fixing plate 10 .

[0044] In this embodiment, before the first electric meter 2 is replaced, the conductive block 11 is placed in the corresponding placement slot 12, and then under the action of external force, the driving unit drives the conductive block 11 to contact the conductive spring sheet 23, and at the same time, the fixing plate 10 is fixedly connected to the meter box 1, so that after the first electric meter 2 is replaced, the second electric meter 9 can also be removed, thereby saving costs.

[0045] As an implementation method, Figure 3 , Figure 4 and Figure 5 As shown, the driving unit includes:

[0046] An inner cavity 13 is provided in the fixing plate 10, a rotating column 17 passes through the inner cavity 13, and a gear 14 is fixed to the rotating column 17, the rotating column 17 is located between the inlet and outlet of the third electric meter, and the gear 14 is located in the inner cavity 13;

[0047] A rectangular block and a screw 21 fixed to the bottom end of the rectangular block, a rectangular hole 2018 is provided on the bottom end surface of the rotating column 17, and the rectangular block is slidably connected to the rectangular hole 2018;

[0048] A spring 19 with one end fixed to the top of the rectangular hole 2018, and the other end of the spring 19 fixed to the top of the rectangular block;

[0049] Two connecting rods 15 and a push rod 16 with one end fixed to the connection, the push rod 16 corresponds to the placement slot 12 one by one, and the top of the push rod 16 is provided with an extension end extending to the corresponding placement slot 12, one of the connecting rods 15 is located above the gear 14, and the other connecting rod 15 is located below the gear 14, and the connecting rod 15 is provided with a spur rack meshing with the gear 14.

[0050] In this embodiment, after the conductive block 11 is located in the corresponding placement groove 12, the screw 21 is aligned with the screw hole provided on the inner wall of the metering box 1. Under the elastic force of the spring 19, the screw 21 contacts the screw hole, and then the rotating column 17 is rotated. At this time, the screw 21 will gradually enter the screw hole, and at the same time will drive the two connecting rods 15 to move relative to each other, thereby driving the push rod 16 to apply pressure on the conductive block 11 to move in the direction of the conductive spring sheet 23, and finally make the conductive block 11 contact with the conductive spring sheet 23.

[0051] As an implementation method, Figure 2 As shown, it includes a limit frame 22 arranged on the inner wall of the meter box 1, where the limit frame 22 is used to place the second electric meter 9.
