DETAILED DESCRIPTION
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] As attached Figures 1-9 The multi-module integrated power metering box shown uses a control component on the box body 1. The first electromagnet 3 and the second electromagnet 4 are driven by electromagnetic force to move axially along the central cylinder 6. Combined with the linkage structure of the first crossbar 11, the second crossbar 12, and the top rod 14, the contact state between the current shunt 8 and the elastic conductive pin 7 can be precisely controlled, achieving automatic current distribution and path switching. Simultaneously, the current inverter 25 is connected to the current shunt 8 via wires, allowing for real-time conversion of different current parameters, easily and quickly adapting to multi-current scenarios. The specific structural configuration of the components is as follows.
[0034] The control component includes a protective cylinder 2 installed inside the housing 1. A first electromagnet 3 is installed in the middle of the protective cylinder 2, a second electromagnet 4 is installed at the bottom of the first electromagnet 3, and a reinforcing conductive ring 5 is installed at the top of the first electromagnet 3. The magnetic poles of the first electromagnet 3 and the second electromagnet 4 are the same at their closest points.
[0035] As attached Figure 3 , 5 As shown in Figures 7, 8, and 9, when the second electromagnet 4 and the first electromagnet 3 are connected to the current, the magnetic poles of the first electromagnet 3 and the second electromagnet 4 are the same, generating a repulsive force, which in turn allows the second electromagnet 4 and the first electromagnet 3 to move up and down along the axial direction of the protective cylinder 2 inside the protective cylinder 2.
[0036] The top of the reinforcing conductive ring 5 is provided with a central cylinder 6. Several elastic conductive pins 7 are distributed on the outside of the central cylinder 6, and a shunt 8 is provided at the top of each elastic conductive pin 7. The bottom end of the elastic conductive pin 7 is embedded in the top of the inner cavity of the protective cylinder 2. Several shunts 8 are hinged to the outside of the central cylinder 6, each located at the top of the corresponding elastic conductive pin 7.
[0037] As attached Figure 5 and 9 As shown, when the shunt 8 deflects outside the central cylinder 6, it can contact the elastic conductive pin 7, so that the elastic conductive pin 7 can transfer the current to the shunt 8 for shunt transmission.
[0038] A first crossbar 11 is provided on one side of the first electromagnet 3, and a second crossbar 12 is provided on one side of the second electromagnet 4. The first crossbar 11 and the second crossbar 12 are both placed horizontally on the protective cylinder 2. The bottom of the first crossbar 11 and the top of the second crossbar 12 are respectively provided with inclined grooves 13, and each inclined groove 13 is slidably connected with a top rod 14. A spring 23 is embedded between the two top rods 14.
[0039] As attached Figure 3 , 5 As shown in 7, 8 and 9, when the first horizontal bar 11 and the second horizontal bar 12 move laterally on the protective cylinder 2, the inclined groove 13 on the first horizontal bar 11 contacts the top rod 14 at the bottom of the first horizontal bar 11, which causes the top rod 14 to move downward and compress the spring 23. Driven by the spring 23, the top rod 14 at the top of the second horizontal bar 12 moves downward and abuts against the inclined groove 13 opened on the second horizontal bar 12, which allows the second horizontal bar 12 to move laterally on the protective cylinder 2.
[0040] The outer side of the first electromagnet 3 is provided with a plurality of first triangular grooves 15, and the outer side of the second electromagnet 4 is provided with a plurality of second triangular grooves 16, and each first crossbar 11 and second crossbar 12 is slidably connected to the corresponding first triangular groove 15 and second triangular groove 16 respectively.
[0041] As attached Figure 7 , 8 As shown in Figure 9, when the second electromagnet 4 and the first electromagnet 3 are displaced along the axial direction of the protective cylinder 2, the first electromagnet 3 contacts the first crossbar 11 through the first triangular groove 15, and the second electromagnet 4 contacts the second crossbar 12 through the second triangular groove 16. This drives the first crossbar 11 and the second crossbar 12 to move laterally on the protective cylinder 2. This allows the spring 23 to be compressed through the inclined groove 13 and the top rod 14 when the first crossbar 11 and the second crossbar 12 move laterally. This facilitates the second crossbar 12 and the first crossbar 11 to support the second electromagnet 4 and the first electromagnet 3 respectively, preventing the first electromagnet 3 and the second electromagnet 4 from being in an elastic support state after the power is cut off. It also facilitates the controllable displacement stroke of the first electromagnet 3 and the second electromagnet 4 when the current is turned on, as the magnetic poles of the first electromagnet 3 and the second electromagnet 4 are the same and generate a repulsive force.
[0042] Limiting plates 17 are respectively provided at one end of the first crossbar 11 and the second crossbar 12 on the outside of the protective cylinder 2. A second misalignment groove 22 is opened on the outside of the protective cylinder 2, and the limiting plate 17 is embedded in the second misalignment groove 22.
[0043] As attached Figure 2 , 4As shown in 7, 8 and 9, the second misalignment groove 22 is set to avoid interference between the limiting plate 17 and the protective cylinder 2, so that the bottom end of the limiting plate 17 can be embedded in the protective cylinder 2.
[0044] One end of the shunt 8 is hinged to a deflector 9, and the end of the deflector 9 away from the shunt 8 is hinged to a handle 10. The top of the protective cylinder 2 is provided with a protective ring 20, and a number of first misalignment grooves 21 are opened on the protective ring 20. A number of current inverters 25 are distributed at the bottom of the protective ring 20, and each current inverter 25 is connected to the corresponding shunt 8 through a wire.
[0045] As attached Figure 2 , 4 As shown in Figures 5 and 6, by turning the handle 10, the angle of the deflector 9 can be adjusted. When the deflector 9 deflects, it can drive the shunt 8 to deflect outside the central cylinder 6, so that the shunt 8 can contact the top of the elastic conductive pin 7, so that the elastic conductive pin 7 can transmit the current to the current inverter 25 through the shunt 8.
[0046] The bottom of the protective cylinder 2 is bolted to a base plate 18, on which an electrode 19 is provided. The top of the electrode 19 passes through the second electromagnet 4, the first electromagnet 3 and the central cylinder 6 in sequence and extends to the top of the housing 1. The electrode 19 transmits current to the shunt 8 through the reinforcing conductive ring 5.
[0047] As attached Figure 1 , 2 As shown in Figures 3 and 5, electrode 19 transmits the current to the shunt 8 through the reinforcing conductive ring 5, which facilitates the shunt transmission of the current. When the current is turned on through electrode 19, it is also convenient for the second electromagnet 4 and the first electromagnet 3 to be energized to generate a repulsive force to drive the first electromagnet 3 and the second electromagnet 4 to move.
[0048] A cabinet door is hinged to one side of the surface of the box 1, and a protective railing 24 is embedded in the top of the box 1.
[0049] As attached Figure 1 As shown, the cabinet door allows for easy opening of the cabinet to disassemble and maintain the control components inside the housing 1, while the protective railing 24 provides protection for the top of the electrode 19.
[0050] The vertical cross-sectional shape of the first triangular groove 15 and the second triangular groove 16 is set as a triangle. The first electromagnet 3 and the second electromagnet 4 are respectively provided with conductive rings, and the conductive rings are slidably connected to the electrode 19. The top of the electrode 19 is provided with a terminal extending to the outside of the box 1.
[0051] As attached Figure 7 , 8As shown in Figs. 8 and 9, the triangular cross-section of the first triangular slot 15 and the second triangular slot 16 facilitates the displacement of the first horizontal rod 11 and the second horizontal rod 12 along the second triangular slot 16 and the first triangular slot 15 of the protective cylinder 2 when the first electromagnet 3 and the second electromagnet 4 are displaced. The conductive ring facilitates the transmission of the current on the electrode 19 to the first electromagnet 3 and the second electromagnet 4.
[0052] A plurality of handles 10 are respectively located in the corresponding first staggered slots 21 and are hingedly connected to the protective ring 20. The central cylinder 6 is located in the middle of the protective ring 20.
[0053] As shown in Figs. 10 and 11, the first staggered slots 21 stagger the interference between the central cylinder 6 and the handles 10 and the protective ring 20, and facilitate the positioning of the central cylinder 6. Figure 2 4 As shown in Figs. 10 and 11, the first staggered slots 21 stagger the interference between the central cylinder 6 and the handles 10 and the protective ring 20, and facilitate the positioning of the central cylinder 6.
[0054] The specific working principle is as follows: when the current is input through the electrode 19, the current is conducted to the conductive ring in the first electromagnet 3 and the second electromagnet 4 through the electrode 19. The force of the first electromagnet 3 and the second electromagnet 4 follows the law of same sex repulsion and opposite sex attraction. If the two adjacent magnetic poles are the same, repulsion force is generated; if the two adjacent magnetic poles are opposite, attraction force is generated. The two adjacent magnetic poles are the same, and the repulsion force drives the first electromagnet 3 to move upward and the second electromagnet 4 to move downward along the axis of the central cylinder 6. At this time, the first triangular slot 15 on the outside of the first electromagnet 3 pushes the first horizontal rod 11 to slide horizontally on the central cylinder 6, and the second triangular slot 16 of the second electromagnet 4 synchronously drives the second horizontal rod 12 to move horizontally. The triangular cross-section design of the triangular slot ensures the stability of the horizontal rod, and the limiting plate 17 on the horizontal rod is embedded in the second staggered slot 22 of the central cylinder 6 to prevent the horizontal rod from being excessively displaced.
[0055] When the first horizontal rod 11 and the second horizontal rod 12 move horizontally, the inclined slots 13 at the bottom and the top thereof are in contact with the top rod 14. The inclined surface of the inclined slot 13 pushes the top rod 14 to compress the spring 23 downward, so that the two first horizontal rods 11 and the second horizontal rod 12 form an elastic linkage through the top rod 14 and the spring 23. When the first electromagnet 3 and the second electromagnet 4 are energized, the displacement is driven by the electromagnetic repulsion force, and when the first electromagnet 3 and the second electromagnet 4 are de-energized, the first horizontal rod 11 and the second horizontal rod 12 are supported by the elastic force of the spring 23, thereby avoiding the free falling of the first electromagnet 3 and the second electromagnet 4, achieving precise control of the displacement stroke and structural stability.
[0056] By turning the handle 10, the deflector 9 drives the shunt 8 to deflect outside the central cylinder 6. When the shunt 8 contacts the elastic conductive pin 7, the current of the electrode 19 is transmitted to the shunt 8 through the reinforced conductive ring 5, and is connected to the current frequency converter 25 at the bottom of the protection ring 20 through the wire. The current frequency converter 25 converts the current parameters according to the needs, realizes independent regulation and control and combing output of multi-module current. The compression rebound of the elastic conductive pin 7 contacts the shunt 8, which ensures the close contact between the shunt 8 and the pin, and avoids the conductive loss.
[0057] The above only is the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
