DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figures 1 to 6 A three-chamber structure smart meter box includes an electric meter box 1, wherein a main switch chamber 2, a main meter box 3 and an outgoing line switch chamber 4 are arranged inside the electric meter box 1, a vertical partition 5 is arranged between the main switch chamber 2 and the main meter box 3, the outgoing line switch chamber 4 is arranged below the main switch chamber 2 and a horizontal partition 6 is arranged between the main switch chamber 2, the main switch chamber 2 includes a main electric meter mounting plate 7 and a main control switch assembly 8, the main control switch assembly 8 includes a main control switch 81, an active ratchet mechanism 82, a driven ratchet mechanism 83 and a driving motor assembly 84, and an outgoing line switch mounting plate 41 is arranged in the outgoing line switch chamber 4.

[0030] In this embodiment, Figures 1 to 6 As shown, the active ratchet mechanism 82 is arranged below the master control switch 81, and includes an active ratchet 821 and an active pawl 822. The active ratchet mechanism 82 is rotatably connected to the bottom of the master control switch 81 through the end of the active pawl 822, and the bottom of the active pawl 822 is connected to the base of the master control switch 81 through a spring 9.

[0031] A driving motor assembly 84 is installed on the vertical partition 5 , a driven ratchet mechanism 83 is installed inside the vertical partition 5 , the driven ratchet mechanism 83 is installed in parallel with the active ratchet mechanism 82 through the rotating shaft 11 , and a first electromagnetic block 10 is installed in the middle position of the front side of the vertical partition 5 .

[0032] Specifically, the electric meter box 1 is functionally partitioned by vertical partitions 5 and horizontal partitions 6, and a main switch room 2 is separately provided. By providing a master control switch assembly 8 and a first electromagnetic block 10, the structure of the electric meter box 1 has the advantages of being able to separately provide each switch room for easy maintenance and ensuring the safety of household electricity use, and also has the advantages of protecting maintenance safety.

[0033] In this embodiment, a through hole for installing the drive motor assembly 84 and passing cables is opened on the vertical partition 5, and the drive motor assembly 84 is installed and fixed on the vertical partition 5 through the through hole on the vertical partition 5.

[0034] The driven ratchet mechanism 83 includes a driven ratchet 831 and a driven pawl 832 . The driven pawl 832 is connected to the first electromagnetic block 10 via a spring 9 . A second electromagnetic block 16 is fixedly mounted on the inner side of the cover plate 15 . The position of the second electromagnetic block 16 corresponds to that of the first electromagnetic block 10 .

[0035] The drive motor assembly 84 includes a drive motor 841, a temperature controller 842, a mounting cover 843 and two sprocket assemblies 844. The drive motor 841 is arranged inside the mounting cover 843 and installed on one side of the main metering box 3. The two sprocket assemblies 844 cooperate with the drive motor 841 and are respectively installed on both sides of the vertical partition 5.

[0036] The two sprocket assemblies 844 are respectively and laterally fixedly connected with a push rod 12 and an ejector device 13. The push rod 12 is arranged above the master control switch 81, and the ejector device 13 is arranged on one side of the main metering box 3. The ejector device 13 includes an ejector 131 and an ejector mounting plate 132. The ejector 131 is fixedly mounted on the ejector mounting plate 132.

[0037] Specifically, when the master switch 81 is disconnected, the active ratchet mechanism 82 rotates and transmits the rotation to the driven ratchet mechanism 83 through the rotating shaft 11, the driven ratchet 831 rotates and the driven pawl 832 opens, and the driven pawl 832 pulls the spring 9 to cut off the power to the first electromagnetic block 10 on the vertical partition 5, thereby disconnecting the first electromagnetic block 10 on the vertical partition 5 from the second electromagnetic block 16 on the cover plate 15, ensuring that personnel can open the cover plate 15 for maintenance only when the master switch 81 is disconnected, and the cover plate 15 cannot be opened when the master switch 81 is closed. It makes it impossible to work with electricity to ensure the safety of personnel; when the temperature controller 842 detects that the temperature in the meter box 1 is abnormal, the drive motor 841 starts to work, and the drive motor 841 drives the two sprocket assemblies 844 to work. The two sprocket assemblies 844 respectively control the push rod 12 to descend and the ejector device 13 to rise. The descent of the push rod 12 causes the main control switch 81 to be disconnected. By arranging the drive motor assembly 84 on the vertical partition 5 to automatically disconnect the circuit when a short circuit or a circuit hazard occurs, the safety of electricity use is guaranteed, and the meter box has the advantage of automatically disconnecting the main circuit when a circuit hazard occurs.

[0038] In this embodiment, the main metering box 3 is provided with a meter mounting plate 31, an alarm device 32 and a dry powder bin 33. The dry powder bin 33 is arranged at the top of the main metering box 3 and is located above the ejector device 13. A plurality of dry powder airbags 331 are arranged inside the dry powder bin 33 and a through hole is opened at the bottom to cooperate with the ejector 131.

[0039] A mounting seat 14 is provided on the outside of the meter box 1, and an inlet hole and an outlet hole are provided on the left side of the meter box 1. Cover plates 15 are provided above the main switch room 2, the main metering box 3 and the outlet switch room 4, respectively. The cover plates 15 are hingedly installed with the meter box 1 and an observation window 151 is provided on the upper side.

[0040] A through hole cooperating with the main control switch 81 is provided on the upper cover plate 15 of the main switch chamber 2 .

[0041] Specifically, when the temperature sensing controller 842 detects that the temperature in the meter box 1 is abnormal, the driving motor 841 controls the ejector device 13 to rise. However, when the ejector device 13 rises to a certain height, the ejector pin 131 on the ejector device 13 pierces the dry powder airbag 331 arranged inside the dry powder bin 33, so that the dry powder in the dry powder airbag 331 extinguishes the circuit in the meter box 1. An observation window 151 is provided on each cover plate 15 to facilitate maintenance personnel to observe the internal circuit of the meter box 1 for preliminary judgment. The main control switch 81 is exposed to the outside of the meter box 1 through a through hole provided on the upper cover plate 15 of the main switch room 2, so that the main control switch 81 can be cut off when needed. The meter box 1 is provided with an alarm device 32 and a dry powder bin 33 to facilitate timely extinguishing of the open fire and timely reminder through the alarm device 32 if a short circuit occurs in the circuit after the main control switch 81 is disconnected.

[0042] Working principle: When the three-chamber structure smart meter box is used, a person first needs to disconnect the main control switch 81 outside the meter box 1. The disconnection of the main control switch 81 drives the active pawl 822 on the active ratchet mechanism 82 to rotate, and the rotation of the active pawl 822 causes the active ratchet 821 to rotate. The rotation of the active ratchet 821 is transmitted to the driven ratchet mechanism 83 through the rotating shaft 11, so that the driven ratchet 831 rotates and the driven pawl 832 opens, pulling the spring 9 between the driven pawl 832 and the first electromagnetic block 10, so that the first electromagnetic block 10 is disconnected from the second electromagnetic block 16 on the cover plate 15, which is convenient for personnel to disconnect the main control switch. When the master switch 81 is turned off, the first electromagnetic block 10 and the second electromagnetic block 16 are disconnected, so that the cover 15 is easy to open for maintenance, and when the master switch 81 is closed, the first electromagnetic block 10 and the second electromagnetic block 16 are locked so that the cover 15 cannot be opened. When the temperature controller 842 senses that a certain temperature has been reached in the main metering box 3, the drive motor assembly 84 controls the drive motor 841 to drive the two sprocket assemblies 844 to drive the push rod 12 to descend, so that the master switch 81 is disconnected and the ejector device 13 rises to pierce the dry powder air bag 331 inside the dry powder bin 33, thereby extinguishing the internal circuit of the main metering box 3 and the alarm device 32 flashes and beeps to give timely reminders.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
