[0001] The present invention relates to a power grid meter box, and in particular to a modular smart power grid meter box applied in the field of power grid boxes. Background Art

Smart meters are usually equipped with a switch function. As an important facility for electric energy metering and management, the design and function of the meter box must meet the requirements of safety, reliability and convenience. Choosing a suitable meter box is crucial to ensuring the stable operation of the power system and the safety of users' electricity use.

[0003] The specification of Chinese utility model patent CN218678105U discloses an electric meter box. Through the storage components provided, the tools used by the staff to maintain the main body of the electric meter box can be stored. At the same time, it is also convenient for the staff to quickly take out the required multiple tools, which solves the problem that the staff needs to carefully search for the required tools in the storage bag during the actual maintenance process, thereby improving the work efficiency of the staff, facilitating the staff to carry out work when maintaining the main body of the electric meter box, and improving the practicality of the main body of the electric meter box.

[0004] During use, the above-mentioned meter box did not provide protection for the meter's switch, resulting in the maintenance personnel's belts or cables of other equipment being hooked on the switch during actual operation, and driving the switch upward when the maintenance personnel performed a lifting action, causing the power to be on during maintenance, which is not conducive to safe maintenance operations.

[0007] In order to solve the above problems, the present invention provides a modular smart grid meter box, comprising a plurality of meter bodies installed in the meter box and a pull-switch installed on one side of the meter body, and each row of meter bodies in the meter box is installed on a bottom plate and plugged into the inside of the meter box, a rotating part is installed on the surface of the pull-switch, and electromagnetic blocks and limit plugs arranged up and down are installed on the outer walls of both sides of the pull-switch, a magnetic drop plate that attracts the electromagnetic block is slidably connected inside the limit plug, a sliding groove is provided on the surface of the magnetic drop plate, a bell with a lever is inlaid on the surface of the magnetic drop plate, a moving block is slidably connected inside the sliding groove, and a spring bar located below the moving block is connected to the bottom wall of the sliding groove;

[0008] The two side surfaces of the pull-gate switch are equipped with linkage rods located below the magnetic falling plate through pin shaft rods, and the ends of the linkage rods are fixedly connected to the surface of the pull-gate switch. The surface of the pin shaft rod is provided with a plurality of surrounding limit grooves, and air cushion plates are installed at the bottom of the two side surfaces of the magnetic falling plate.

[0009] In the above-mentioned modular smart grid meter box, the electromagnetic block, limit slot and magnetic drop plate as well as the cooperation of the bell and the moving block are utilized to ensure that the switch can be locked in the maintenance state and can send out prompts for the hooking and driving effect generated during the maintenance process, so as to remind the circuit maintenance personnel in the maintenance operation state to make corrective adjustments in time.

[0010] As a further improvement of the present application, the surface of the pin shaft rod is fixedly connected to the linkage rod, and the pin shaft rod is rotationally connected to the surface of the pull switch.

[0011] As a further improvement of the present application, the sum of the thicknesses of the two air cushion plates and the magnetic falling plate is not greater than the cross-sectional width of the limiting groove, and the outer surface of the portion of the air cushion plate located above the limiting groove is sleeved with an open protective cover made of rigid material.

[0012] As a further improvement of the present application, the initial elastic force of the spring bar is equal to the self-gravity value of the moving block, the cross-section of the moving block is convex-shaped and the surface of the moving block protrudes from the surface of the sliding groove, and the bell lever is located directly above the inner part of the moving block in the sliding groove.

[0013] As a further improvement of the present application, the vertical distance between the limit block and the bottom end of the limit slot at the uppermost position is H1, the vertical distance between the electromagnetic block and the topmost surface of the pin shaft rod is H2, and the length of the magnetic falling plate is greater than H1 and less than H2.

[0014] As a further improvement of the present application, a heat dissipation window is provided through the surface of the meter box, and a one-way valve is installed inside the heat dissipation window.

[0016] As another improved supplement of the present application, one end of the fixed round rod extends to the inside of the pin rod, and the fixed round rod is rotatably connected to the surface of the pin rod.

[0017] As another improvement supplement of the present application, the cross-sectional area of ​​the suspension plate is smaller than the cross-sectional area of ​​the sinking groove, the length value of the sinking groove is smaller than the length value of the limiting groove, the tail end of the suspension plate corresponds one-to-one with the constraint slot and in the initial state the suspension plate is located above the constraint slot, and the vertical distance between the tail end of the suspension plate and the top of the constraint slot is less than half of the depth value of the constraint slot itself.

[0018] To summarize, the present application utilizes a combination of an electromagnetic block, a magnetic drop plate and a limit groove. When the magnetic drop plate is adsorbed to the bottom of the electromagnetic block, the bottom of the magnetic drop plate will not be plugged into the limit groove, thereby not affecting the rotation of the pin shaft rod. Therefore, when it is necessary to push and pull the gate in the future, the magnetic drop plate does not need to be pushed manually, thereby achieving a more convenient circuit recovery operation, and the locking and restraining effect of the pin shaft rod can be achieved when the electromagnetic block is started, thereby avoiding accidental pushing operations by unrelated personnel. In addition, during the working process, in order to avoid the entanglement of the maintenance personnel's belts or the cables of the equipment on the surface, the rotation trend of the pin shaft rod is used to drive the limiting groove to squeeze the air cushion board, so that the top of the air cushion board is quickly lifted up and then the lever of the bell is turned to emit a prompt sound, thereby achieving a corresponding prompt effect.

[0032] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 7 A modular smart grid meter box is shown, comprising a plurality of meter bodies installed in a meter box 2 and a switch 1 installed on one side of the meter body, and each row of meter bodies in the meter box 2 is installed on a bottom plate and plugged into the inside of the meter box 1, a rotating part is installed on the surface of the switch 1, and both sides of the switch 1 are installed with electromagnetic blocks 4 and limit plugs 5 arranged up and down, and the limit plugs 5 are slidably connected to the inside of the limit plugs 5 and mutually attracted to the electromagnetic blocks 4, and the surface of the magnetic drop plate 6 is provided with a sliding groove 61, and the surface of the magnetic drop plate 6 is inlaid with a bell 62 with a lever, and the sliding groove 61 is slidably connected to the inside of the moving block 63, and the bottom wall of the sliding groove 61 is connected to a spring bar 64 located below the moving block 63;

[0035] The two side surfaces of the pull-switch 1 are equipped with a linkage rod 3 located below the magnetic falling plate 6 through a pin shaft rod 7, and the end of the linkage rod 3 is fixedly connected to the surface of the pull-switch, and the surface of the pin shaft rod 7 is provided with a plurality of surrounding limiting grooves 9, and the bottom of the two side surfaces of the magnetic falling plate 6 are equipped with air cushion plates 8.

[0036] The surface of the pin shaft rod 7 is fixedly connected to the linkage rod 3 , and the pin shaft rod 7 is rotatably connected to the surface of the pull switch 1 .

[0037] Specifically, each row of electric meter bodies in the electric meter box 2 is mounted on a bottom plate and plugged into the inside of the electric meter box 1 , and subsequent installation and removal of the electric meter bodies can be carried out in batches, thus realizing modular processing.

[0038] When the electromagnetic block 4 is started, the magnetic drop plate 6 can be adsorbed on the bottom of the electromagnetic block 4 by means of magnetic attraction, so that the magnetic drop plate 6 is separated from the limit groove 9, so that the pin shaft rod 7 can rotate smoothly, and with the help of the fixed connection between the linkage rod 3, the linkage rod 3 and the pull switch connected to the tail end of the linkage rod 3 are driven to rotate, thereby realizing the reset of the pull switch;

[0039] Through remote control, after the electromagnetic block 4 is turned off, the magnetic drop plate 6 falls into the limit groove 9 on the surface of the pin shaft rod 7, which locks the maintenance state of the switch to avoid potential safety accidents caused by unauthorized personnel pushing the switch by mistake;

[0040] During maintenance, if the maintenance personnel's belt or equipment cable is hooked on the linkage rod 3 and drives the switch to be pushed up, the air cushion plate 8 is squeezed, and the top of the rapidly expanding and lifting air cushion plate 8 pushes the moving block 63 to move up and hit the lever of the bell 62, thereby issuing a warning sound, so that the maintenance personnel who are in the maintenance state can correct the hooking state in time.

[0041] Air cushion plates 8 are installed at the bottom of the two side surfaces of the magnetic falling plate 6, the sum of the thickness values ​​of the two air cushion plates 8 and the magnetic falling plate 6 is not greater than the cross-sectional width value of the limiting groove 9, and the outer surface of the part of the air cushion plate 8 located above the limiting groove 9 is sleeved with an open protective cover made of rigid material.

[0042] Specifically, the portion of the air cushion board 8 located in the limiting groove 9 is designed to be exposed, and the outer surface of the portion located above the limiting groove 9 is connected to a protective cover of an open design made of a rigid material. Therefore, the extrusion effect generated by the rotation tendency of the pin shaft rod 7 in the portion of the air cushion board 8 located in the limiting groove 9 will cause the top of the air cushion board 8 to move upward (because the gas inside the air cushion board 8 is squeezed and intercepted and constrained by the protective cover and the bottom end of the limiting groove 9, the expanded and deformed portion can only be squeezed out from the open top of the protective cover, forming a lifting effect). After the plate 8 follows the magnetic falling plate 6 and enters the limiting groove 9 at the same time, due to the size design between the air cushion plate 8 and the magnetic falling plate 6 and the limiting groove 9, when the magnetic falling plate 6 falls vertically, the inside of the limiting groove 9 will not produce an squeezing effect on the air cushion plate 8, and then when there is an upward pushing tendency when the gate is pulled later, so that the pin shaft rod 7 has a rotation tendency, the inner wall of the limiting groove 9 produces an squeezing effect on the air cushion plate 8, thereby causing the air cushion plate 8 to be squeezed and deformed, indirectly causing the bell 62 to emit a ringing sound, which serves as a reminder.

[0043] The initial elastic force of the spring bar 64 is equal to the self-gravity value of the moving block 63. The cross-section of the moving block 63 is convex and the surface of the moving block 63 protrudes from the surface of the sliding groove 61. The lever of the bell 62 is located directly above the inner part of the moving block 63 in the sliding groove 61.

[0044] Specifically, the spring bar 64 is in contact with the moving block 63. Therefore, when the moving block 63 is rapidly moved upward along the inner wall of the sliding groove 61 by the expansion and lifting effect of the air cushion plate 8, it will hit the lever of the bell 62 upward, thereby causing the bell 62 to make a sound, thereby sending out a prompt to the outside, reminding the maintenance staff that the linkage rod 3 is in the process of driving the switch upward, so that they can check the situation at the switch 1 in time and release the entanglement state that causes the driving effect.

[0045] The vertical distance between the limit block 5 and the bottom end of the limit slot 9 at the uppermost position is H1, the vertical distance between the electromagnetic block 4 and the topmost surface of the pin shaft rod 7 is H2, and the length of the magnetic falling plate 6 is greater than H1 and less than H2.

[0046] Specifically, the setting of the magnetic falling plate 6 ensures that when the magnetic falling plate 6 is adsorbed to the bottom of the electromagnetic block 4, the bottom of the magnetic falling plate 6 will not be plugged into the limit groove 9, thereby not affecting the rotation of the pin shaft rod 7. The power supply can be restored by manually pushing up and pulling the switch. In addition, when the electromagnetic block 4 is closed and causes the magnetic falling plate 6 to fall, the magnetic falling plate 6 is plugged into the inside of the limit groove 9 while the top of the magnetic falling plate 6 is still located above the limit plug 5. In this process, the limit plug 5 is used to control the movement path of the magnetic falling plate 6 to be in a vertical state.

[0047] A heat dissipation window is provided through the surface of the electric meter box 2, and a one-way valve is installed inside the heat dissipation window.

[0048] Specifically, the meter box 2 can provide external protection for the pull switch 1, thereby preventing external impact from causing damage to the pull switch 1. In addition, the heat dissipation window equipped with a one-way valve is beneficial for providing heat dissipation services for the pull switch 1 in the working state.

[0049] Second implementation method:

[0050] Figure 8-Figure 11, wherein the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: a fixed round rod 10 is fixedly installed through the outer walls of both sides of the pull switch 1, a restraining slot 11 is arranged around one end surface of the fixed round rod 10, a symmetrically arranged sinking groove 91 is arranged on the bottom wall of the limit groove 9, a symmetrically arranged spring cable 92 is obliquely connected to the top wall of the sinking groove 91, and a hanging plate 93 is connected to the end of the spring cable 92.

[0051] One end of the fixed round rod 10 extends to the inside of the pin shaft rod 7, and the fixed round rod 10 is rotatably connected to the surface of the pin shaft rod 7.

[0052] The cross-sectional area of ​​the suspension plate 93 is smaller than the cross-sectional area of ​​the sinking groove 91, the length of the sinking groove 91 is smaller than the length of the limit groove 9, the tail end of the suspension plate 93 corresponds one-to-one to the constraint slot 11 and in the initial state the suspension plate 93 is located above the constraint slot 11, and the vertical distance between the tail end of the suspension plate 93 and the top of the constraint slot 11 is less than half of the depth value of the constraint slot 11 itself.

[0053] Specifically, when the pin shaft rod 7 is locked and the rotation of the pin shaft rod 7 caused by the upward push of the gate is resisted, the bottom end of the magnetic falling plate 6 is squeezed with the inside of the limiting groove 9. Since the contact depth between the bottom end of the magnetic falling plate 6 and the limiting groove 9 is limited, it is easy to cause the bottom end of the magnetic falling plate 6 to be fractured and damaged, affecting the use of the magnetic falling plate 6. In order to avoid the above phenomenon, this embodiment is adopted;

[0054] Since the fixed round rod 10 is fixedly connected to the pull switch 1, and the fixed round rod 10 is rotatably connected to the pin shaft rod 7, the pin shaft rod 7 can be sleeved on the surface of the fixed round rod 10 and rotated;

[0055] When the pull gate with an upward push-up tendency drives the pin shaft rod 7 and the internal limit groove 9 to rotate, the inner wall of the limit groove 9 squeezes the air cushion plate 8, and the upper part of the air cushion plate 8 moves upward to push the moving block 63 upward, and the lower part of the air cushion plate 8 squeezes and moves downward to extend downward through the sinking groove 91, and then squeezes the hanging plate 93, so that it forms a plug-in effect with the constraint slot 11 downward, so that the magnetic falling plate 6 and the hanging plate 93 are both in a plug-in limit state, so that the pin shaft rod 7 can be fixed and constrained on the surface of the fixed round rod 10, preventing the rotation of the pin shaft rod 7, so that the rotation effect of the pin shaft rod 7 against the upward push is strengthened, avoiding the squeezing of the tail end of the magnetic falling plate 6 by the limit groove 9, and thus protecting the tail end of the magnetic falling plate 6 from being squeezed and damaged;

[0056] After the hooking effect is released, the rotation tendency of the pin shaft rod 7 driven thereby stops, and the air cushion board 8 returns to its original state. At this time, the bell 62 stops making sound, and the suspension plate 93 returns to its original position under the action of the spring rope 92.

[0057] In summary, by utilizing the combination of the electromagnetic block 4, the magnetic falling plate 6 and the limiting groove 9, when the magnetic falling plate 6 is adsorbed to the bottom of the electromagnetic block 4, the bottom of the magnetic falling plate 6 will not be plugged into the limiting groove 9, and thus will not affect the rotation of the pin shaft rod 7. The subsequent manual push-up and pull-down operation can realize the power supply restoration operation, and the locking and restraining effect of the pin shaft rod 7 can be achieved when the electromagnetic block 4 is started, thereby avoiding the accidental pushing operation by unrelated personnel. In addition, during the working process, in order to avoid the driving effect of the maintenance personnel's belts or the equipment cables on the surface, the rotation trend of the pin shaft rod 7 is used to drive the limiting groove 9 to squeeze the air cushion board 8, so that the top of the air cushion board 8 is quickly lifted and then the lever of the bell 62 is toggled to emit a prompt sound, thereby achieving the corresponding prompt effect.

[0058] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
