Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, and in particular relates to a power metering box. Background Technology

[0002] An electricity metering box is a device used in power systems. Its main function is to house various electrical components used to measure and record electricity usage. These components may include electricity meters, communication modules, controllers, and other electrical devices. Regardless of the specific application, the electricity metering box is always equipped with appropriate power switches to protect these components from overload and short circuits, and to manually or automatically disconnect the circuit in case of a fault.

[0003] Normally, power switches have protective functions and will cut off the circuit when a problem occurs. However, in some special situations, such as a fire, if the circuit is still energized, the power switch needs to be turned off manually. But in this scenario, directly turning off the power switch by hand is extremely dangerous. Summary of the Invention

[0004] The purpose of this invention is to provide an electricity metering box. By incorporating a response component, this invention allows staff to directly operate the response component to shut off the power switch in an emergency, eliminating the need for manual operation and ensuring safety. Furthermore, using the response component to cut off the entire circuit is much faster than directly operating the main switch.

[0005] The technical solution adopted by the present invention to solve the above problems is: an electricity metering box, comprising: The cabinet has a door and a main power switch inside, which is equipped with a mechanical switch. A closing component is provided on the cabinet door, the closing component including a baffle assembly located outside the main power switch, and a response component that closes the main power switch by pressing; The baffle assembly includes a mounting plate, a baffle slidably disposed on the mounting plate, and a lifting plate disposed on the baffle; The response component includes a transmission component and an abutment plate disposed on the transmission component and abutting against the mechanical switch; After the abutment plate pushes the mechanical switch horizontally, the main power switch can be switched to the off state; The transmission assembly is used to horizontally push the abutment plate in the direction of the mechanical switch.

[0006] Optionally, in some embodiments, the transmission assembly includes a movable column, a compression ball disposed at the bottom of the movable column, and a pressure plate disposed outside the abutment plate and abutting against the compression ball; The lifting plate has a cavity, and at least a portion of the transmission assembly and the pressure plate are disposed in the cavity; The contact surface between the pressure plate and the extrusion ball is set as an inclined surface.

[0007] Optionally, in some embodiments, a reset tension spring is provided between the extrusion ball and the inner side of the lifting plate, a limiting plate is provided on the pressure plate, and a tension spring is fixedly connected between the limiting plate and the baffle.

[0008] Optionally, in some embodiments, a limiting disc is provided at the top of the movable column.

[0009] Optionally, in some embodiments, a groove is provided on one side of the mounting plate, and a retaining strip is fixedly connected to the side of the baffle, the retaining strip being slidably disposed inside the groove.

[0010] Optionally, in some embodiments, the inner side of the baffle is provided with a moving groove, and the pressure plate is slidably disposed in the moving groove.

[0011] Optionally, in some embodiments, the cabinet door is provided with a window, and the mounting plate is disposed on the side of the window; Optionally, in some embodiments, two sets of mounting plates are provided, and a connecting frame is installed between the two mounting plates, the connecting frame being located outside the main power switch.

[0012] Optionally, in some embodiments, a protective cover is rotatably connected to the top of the lifting plate.

[0013] Optionally, in some embodiments, the abutment plate is a flexible plate, and the side of the abutment plate near the main power switch is provided with an arc-shaped surface.

[0014] In this embodiment of the invention, when it is necessary to turn off the main power switch, only the response component needs to be operated to directly turn off the mechanical switch of the main power switch through the abutment plate, so as to achieve the effect of indirect shutdown. Furthermore, the main power switch can be directly controlled without opening the cabinet door through the response component, and the response speed is faster.

[0015] In addition, the operator can also use the lifting plate to lift the baffle upwards. At this time, the main power switch is connected to the outside through the window. The operator can simply turn the switch on the main power switch. In case of emergency, the time to open the cabinet door is reduced and the emergency response capability of the device is improved.

[0016] In particular, the response component is mounted on the baffle assembly. Operating the response component opens the baffle, further reducing the time required to shut off the main power switch and making it more convenient to do so. Attached Figure Description

[0020] 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.

[0021] This invention provides an electricity metering box, comprising: Cabinet 1, cabinet door 6 is installed on cabinet 1, and main power switch 4 is installed inside cabinet 1. The main power switch 4 is equipped with a mechanical switch. A closing component is provided on the cabinet door 6. The closing component includes a baffle assembly located outside the main power switch 4, and a response component that closes the main power switch 4 by pressing. The baffle assembly includes a mounting plate 7, a baffle 9 slidably disposed on the mounting plate 7, and a lifting plate 10 disposed on the baffle 9; The response component includes a transmission component and an abutment plate 18 disposed on the transmission component and abutting against the mechanical switch; After the abutment plate 18 pushes the mechanical switch horizontally, the main power switch 4 can be switched to the off state; The transmission assembly is used to horizontally push the abutment plate 18 in the direction of the mechanical switch.

[0022] The cabinet body 1 and cabinet door 6 provide a safe and enclosed environment, protecting the internal electrical components from external environmental influences and preventing unauthorized access. The main power switch 4 controls the circuit switching of the entire power metering box, ensuring normal equipment operation and, in emergencies, cutting off power by closing the mechanical switch to protect the system and personnel. The mechanical switch is an operating component on the main power switch, allowing physical control of the switch's open and closed state.

[0023] In addition, cabinet 1 is usually placed in a container with a security lock, such as a security cabinet or a room with a security door, to ensure that only people with control authority can operate the switch to shut off the circuit.

[0024] The shut-off assembly is used to quickly shut off the main power switch in an emergency using a non-contact method, enhancing operational safety. The baffle assembly aims to protect the main power switch 4 when it is not necessary to shut off the circuit. The response assembly, through the coordinated action of the transmission assembly and the abutment plate 18, achieves non-contact, rapid, and stable shut-off of the main power switch.

[0025] There are many types of switches in the cabinet 1 used to manage the opening or closing of the power supply, but they can be generally divided into a main power switch 4 and several sub-power controllers. The contact plate 18 must be in direct contact with the mechanical switch of the main power switch 4 to ensure that the power supply to all electrical devices in the cabinet 1 can be shut off during operation.

[0026] The transmission assembly includes a moving column 11, a compression ball 13 disposed at the bottom of the moving column 11, and a pressure plate 15 disposed outside the abutting plate 18 and abutting the compression ball 13. The lifting plate 10 has a cavity, and at least a portion of the transmission assembly and the pressure plate 15 are disposed in the cavity; The contact surface between the pressure plate 15 and the extrusion ball 13 is set as an inclined surface.

[0027] A reset tension spring 14 is provided between the squeezing ball 13 and the inner side of the lifting plate 10. A limiting plate 16 is provided on the pressure plate 15. A tension spring 17 is fixedly connected between the limiting plate 16 and the baffle 9.

[0028] The top of the movable column 11 is provided with a limiting plate 12.

[0029] The inner side of the baffle 9 is provided with a moving groove, and the pressure plate 15 is slidably disposed in the moving groove.

[0030] The movable column 11 is a vertically arranged columnar structure, connected to the limiting plate 12 at the top and the compression ball 13 at the bottom. The limiting plate 12 is fixed to the top of the movable column and can be a disc-shaped object. The compression ball 13 is a hemispherical structure, fixed to the bottom of the movable column, and transmits vertical compressive force through contact with the pressure plate 15, causing the pressure plate 15 to move.

[0031] The reset spring 14 is an elastic element connected between the top of the extrusion ball and the inner wall of the lifting plate. Its purpose is to reset the extrusion ball 13 and related components to their initial positions after the force is released. The pressure plate 15 is a plate-shaped structure with its surface in contact with the extrusion ball 13. It can slide within the moving groove, and the contact surface between the pressure plate 15 and the extrusion ball 13 has an arc shape that fits against the extrusion ball 13.

[0032] The limiting plate 16 is a plate sleeved on the surface of the pressure plate 15 to restrict the movement of the pressure plate 15, mainly limiting its lateral movement and ensuring that it slides along a predetermined path in the moving groove. The tension spring, a spring with low elasticity, is connected between the limiting plate and the inner wall of the moving groove, providing additional positioning and restoring force to the pressure plate, ensuring that it quickly returns to its initial position after being pushed. The moving groove is a groove-like structure formed inside the baffle, providing a sliding path for the pressure plate 15, guiding its movement direction, and ensuring that it slides along the predetermined path.

[0033] A groove is provided on one side of the mounting plate 7, and a retaining strip is fixedly connected to the side of the baffle 9. The retaining strip is slidably disposed inside the groove.

[0034] The retaining strip, a long, protruding structure, is fixedly connected to the side of the baffle 9. It slides within the groove of the mounting plate 7, serving to guide and fix the baffle 9, ensuring its smooth movement along the groove. In other words, the groove provides a track, restricting the direction of movement of the baffle 9 and ensuring it slides along a specific path, preventing lateral movement or disengagement.

[0035] The cabinet door 6 is provided with a window, and the mounting plate 7 is located on the side of the window.

[0036] Two sets of mounting plates 7 are provided, and a connecting frame 8 is installed between the two mounting plates 7. The connecting frame 8 is located on the outside of the main power switch 4.

[0037] Furthermore, a key lock is installed on the cabinet door, and a baffle is fixedly connected to one side of the key lock.

[0038] A key lock is a type of lock installed on a cabinet door. It typically consists of a lock cylinder, keyhole, and bolt, and its purpose is to provide physical security and restrict access to the cabinet's internal components. Only a matching key can unlock it, thus preventing unauthorized personnel from opening the cabinet door. A retainer is fixedly attached to one side of the key lock. It is usually a flat piece made of metal or other sturdy material. When locked, the retainer engages in a specific position to prevent the cabinet door from being opened and also provides additional mechanical stability, ensuring the lock is not easily pried open when locked.

[0039] Furthermore, a square groove is provided on the cabinet door, and a latch plate is installed on the cabinet body, with the latch plate located inside the square groove.

[0040] The top of the lifting plate 10 is rotatably connected to a protective cover 19.

[0041] The protective cover 19 can be made of metal, plastic, or other durable materials to resist the effects of the external environment, such as dust, moisture, and physical damage. It can be box-shaped, semi-circular, or other shapes that effectively cover the top of the lifting plate and its surrounding components. The protective cover 19 is connected to the top of the lifting plate via a hinge or pivot, allowing it to rotate open or close.

[0042] The abutment plate 18 is a soft plate, and the side of the abutment plate 18 near the main power switch 4 is provided with an arc-shaped surface.

[0043] A specific embodiment is given below with reference to the accompanying drawings.

[0044] Example: Please combine Figures 1-4 This embodiment of an electricity metering box includes a cabinet 1. An electrical assembly 2 and a connecting plate 3 are installed inside the cabinet 1. A main power switch 4 and a sub-power controller 5 are installed on the surface of the connecting plate 3. A cabinet door 6 is installed on the front of the cabinet 1. A square groove is formed on the front of the cabinet door 6. A latch plate is installed on the front of the cabinet 1, and the latch plate is located inside the square groove to facilitate connecting the cabinet 1 and the cabinet door 6 via a lock. A key lock is installed on the front of the cabinet door 6, and a baffle is fixedly connected to one side of the key lock to connect the cabinet door 6 and the cabinet 1, protecting the components inside the cabinet 1. A control assembly is installed inside the cabinet door 6.

[0045] The control assembly is used to open the baffle 9 and close the main power switch 4. The control assembly includes two mounting plates 7, with connecting frames 8 installed on the back of the two mounting plates 7. A window is opened on the front of the cabinet door 6, and the two mounting plates 7 are respectively set on both sides of the window. The cabinet door 6, the mounting plates 7 and the connecting frames 8 are connected by bolts to facilitate the opening and closing of the main power switch 4 through the window. The connecting frames 8 are set on the outside of the main power switch 4. A baffle 9 is slidably connected between the two mounting plates 7. A groove is opened on one side of the mounting plate 7. Both sides of the baffle 9 are fixedly connected with locking strips, which are slidably set inside the groove to ensure the normal movement of the baffle 9. A lifting plate 10 is installed on the front of the baffle 9, and a change component is installed inside the lifting plate 10.

[0046] The variable assembly is used to turn off the main power switch 4 during the opening of the baffle 9. The variable assembly includes a moving column 11. The top of the lifting plate 10 has a limiting through-hole for the moving column 11 to pass through, ensuring the normal movement of the moving column 11. The top of the moving column 11 is fixedly connected to a limiting plate 12. The top of the lifting plate 10 is rotatably connected to a protective cover 19, which is used to control whether the limiting plate 12 is pressed during use. The bottom of the moving column 11 is fixedly connected to a compression ball 13. The top of the compression ball 13 and the top of the inner wall of the lifting plate 10 are connected by a return spring 14. The surface of the compression ball 13 abuts against a pressure plate 15. The front of the pressure plate 15 is a triangular block, which facilitates the pressure plate 15 to be subjected to the compression ball. The pressure plate 15 is moved at 13 o'clock. A limiting plate 16 is fitted on the surface of the pressure plate 15. A moving groove is opened inside the baffle 9. A through groove is opened on the back of the lifting plate 10 and the front of the moving groove. The pressure plate 15 is slidably set inside the through groove to ensure the normal movement of the pressure plate 15. The pressure plate 15 is slidably set inside the moving groove. Two tension springs 17 are fixedly connected to the front of the limiting plate 16. The front of the tension springs 17 is fixedly connected to the front of the inner wall of the moving groove. An abutment plate 18 is fixedly connected to one end of the pressure plate 15. The abutment plate 18 is a rubber plate, and the top and bottom of the back of the abutment plate 18 are provided with arc-shaped surfaces to reduce the damage caused by the abutment plate 18 when it abuts the surface of the main power switch 4.

[0047] The implementation principle of the power metering box in this application embodiment is as follows: When it is necessary to turn off the main power switch 4, the lifting plate 10 is pulled upward, so that the lifting plate 10 lifts the baffle 9 upward. At this time, the main power switch 4 is connected to the outside through the window, and the operator can directly switch the switch on the main power switch 4. When it is necessary to turn on the main power switch 4, the lifting plate 10 is pulled up to reset the switch on the main power switch 4. The lifting plate 10 enables the control of the main power switch 4 without opening the cabinet door 6, which is very convenient and quick. In case of emergency, it reduces the time to open the cabinet door 6 and improves the emergency response capability of the device.

[0048] In case of emergency, the protective cover 19 can be moved to one side, the limit plate 12 can be pressed, and the lifting plate 10 can be lifted upward. During this process, the limit plate 12 will move downward with the moving column 11, causing the compression ball 13 to press down on the pressure plate 15, causing the pressure plate 15 to move towards the interior of the cabinet 1. This causes the pressure plate 15 to move towards the main power switch 4 with the abutment plate 18. During the process of lifting the lifting plate 10 upward, the abutment plate 18 will abut against the switch on the main power switch 4, causing the switch to be flipped upward. This achieves automatic shutdown of the main power switch 4 during the lifting of the lifting plate 10, which can further reduce the time required to shut down the main power switch 4 and make it more convenient to shut down the main power switch 4.
