Description

Technical Field

[0001] This invention belongs to the field of metering box technology, and specifically relates to an intelligent shared power metering box. Background Technology

[0002] Intelligent shared power metering boxes are integrated power supply terminals designed to meet the needs of temporary power use and convenient power consumption for low-voltage industrial and commercial users. They are mainly deployed in public places with high demand, such as construction sites, temporary markets, and outdoor activities. This product adopts a miniaturized and modular design, allowing users to easily connect the power supply through simple plug-and-play operations, aiming to provide safe and flexible temporary power access services. As a key node in the construction of the ubiquitous power Internet of Things on the customer side, it not only has basic metering and control functions but also integrates security modules such as access control monitoring and strong magnetic interference detection. It is typically equipped with a remote monitoring platform and a mobile APP, constructing a smart power consumption model of "online service, offline application," realizing online management of the entire process from application and use to payment.

[0003] However, in actual operation, metering boxes face a high risk of human-caused damage due to their long-term exposure to unattended open environments, such as prying open the box, technically opening the locks, or malicious tampering with the internal circuitry. Although existing products have been equipped with some status monitoring functions, their detection mechanisms have limitations in terms of reliability and real-time performance. For example, monitoring points may not be fully covered, and the response to non-access-triggered damage (such as side breaching) is insufficient.

[0004] Therefore, in the context of building a ubiquitous power Internet of Things and improving the reliability of electricity services, there is an urgent need for an intelligent security technology that can accurately and in real time detect various destructive behaviors to make up for the shortcomings of existing metering boxes in terms of active and real-time protection capabilities, and to ensure equipment safety and the continuity of power supply services. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent shared power metering box.

[0006] The technical solution of the present invention is as follows:

[0007] A smart shared power metering box includes a box body and a door with a latch. An electric suction door assembly is installed inside the box body. A lock cylinder is installed on the electric suction door assembly. A lock body is rotatably connected to the lock cylinder. A lock hook is installed on the lock body. A pull rope is connected to the lock hook. The other end of the pull rope is connected to a sealing block that is elastically connected to the side wall of the box body. A ventilation hole is opened on the side wall of the box body. When the lock hook is engaged with the latch, the latch causes the door to contact and seal with the box body. The lock hook moves the sealing block through the pull rope and closes the ventilation hole.

[0008] The box is equipped with a rewinding negative pressure assembly, which is connected to the box door via a connecting rope. After the box door and the box body are sealed, the rewinding negative pressure assembly extracts the air from the box.

[0009] The box is equipped with a sensor array for detecting negative pressure inside the box.

[0010] Furthermore, the electric suction door assembly includes an electric suction door box disposed inside the housing, a worm gear rotatably disposed inside the electric suction door box, and a locking motor driven by the worm gear. The electric suction door box is provided with a worm wheel that cooperates with the worm gear, and the lock cylinder is disposed on the worm wheel.

[0011] Furthermore, the side wall of the box is provided with a sliding cavity, which is connected to the outside. The vent is opened on the side of the sliding cavity near the inside of the box. The sealing block is slidably connected to the sliding cavity, and the sealing block is connected to a spring fixed in the sliding cavity.

[0012] Furthermore, the lock hook is equipped with a hook connector, and the contact surface between the hook connector and the lock buckle is an arc-shaped surface. The two ends of the arc-shaped surface are respectively located on the side near the lock hook axis and the side away from the lock hook axis, so that after the arc-shaped surface rotates around the lock hook axis, the lock buckle can drive the box door to contact and seal with the box body.

[0013] Furthermore, the locking hook has a limiting part that connects to the arc-shaped surface, and the limiting part is an arc-shaped surface with the locking hook axis as the center.

[0014] Furthermore, the box body has a placement slot inside, and the winding negative pressure assembly is located in the placement slot. A cover plate is fixed to the opening side of the placement slot, and the cover plate has a notch for the connecting rope to pass through. The winding negative pressure assembly includes a drive motor fixed to the placement slot and a winding wheel rotatably connected inside the placement slot. A negative pressure extraction assembly connected inside the placement slot is driven on one side of the drive motor. The negative pressure extraction assembly connects the internal chamber of the box body to the outside of the box body. The winding wheel is driven by the drive motor through a transmission mechanism. When the box door contacts the sealed box body, the transmission mechanism no longer drives the winding wheel.

[0015] Furthermore, the negative pressure extraction assembly includes a negative pressure cylinder fixed in the placement groove, a reciprocating screw rotatably connected inside the negative pressure cylinder, and a negative pressure piston cooperating with the reciprocating screw. The reciprocating screw is fitted with a sealing sleeve, which is connected to the negative pressure piston and the inner wall of the negative pressure cylinder respectively. The negative pressure cylinder is unidirectionally connected to the chamber of the box and unidirectionally connected to the outside of the box.

[0016] Furthermore, the transmission mechanism includes a transmission box sealed and fixed inside the housing, a transmission pulley rotatably connected inside the transmission box, a meshing gear disc fixed coaxially with the winding reel, and a meshing gear cylinder meshing with the meshing gear disc. There are two transmission pulleys that are driven by a transmission belt. One of the transmission pulleys is driven by a drive motor through a bevel gear set, and the other transmission pulley is slidably connected to a transmission key barrel through a key shaft. The transmission key barrel is connected to the transmission pulley through a spring piece.

[0017] A downward pressing protrusion is inserted between the transmission key barrel and the transmission pulley. One end of the downward pressing protrusion extends out of the transmission box, and the downward pressing protrusion is elastically connected inside the transmission box.

[0018] The meshing gear cylinder is connected to the transmission key barrel, and the meshing gear cylinder and the transmission key barrel are elastically connected.

[0019] Furthermore, a locking slot is provided on the side of the box, and the latch is inserted into the box through the locking slot.

[0020] Furthermore, the side of the cabinet door is provided with a sealing layer that contacts and seals against the cabinet body.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention uses the electric suction door assembly and the locking hook to lock the latch, and the latch drives the door to seal with the box body to form a sealed chamber. The door is closed by the retracting negative pressure assembly, and air is extracted after the door and box body are sealed, so that the sealed chamber is under negative pressure. The negative pressure value of the sealed chamber is continuously monitored by the sensor group, thereby realizing the continuous monitoring of the box body. Attached Figure Description

[0033] 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.

[0034] like Figures 1 to 9 As shown, an intelligent shared power metering box includes a box body 8 and a door 1 equipped with a latch 9. An electric suction door assembly is provided inside the box body 8. A lock cylinder 62 is provided on the electric suction door assembly. The lock cylinder 62 is rotatably connected to a lock body 64 on the same axis. A lock hook 61 is provided on the lock body 64. A pull rope 60 is connected to the lock hook 61. The other end of the pull rope 60 is connected to a sealing block 68 that is elastically connected to the side wall of the box body 8. A vent hole is provided on the side wall of the box body 8. When the lock hook 61 is engaged with the latch 9, the latch 9 causes the door 1 to contact and seal with the box body 8. The lock hook 61 moves the sealing block 68 through the pull rope 60 and closes the vent hole.

[0035] An NFC card reader is installed on the door 1 to control the electric suction door component to unlock, and a corresponding battery is also installed inside the body 8 for temporary power supply during power outages;

[0036] The box body 8 is equipped with a winding negative pressure assembly. The winding negative pressure assembly is connected to the box door 1 through a connecting rope. After the box door 1 contacts and seals with the box body 8, the winding negative pressure assembly extracts the air from the box body 8.

[0037] The housing 8 is equipped with a sensor group 12 for detecting the negative pressure inside the housing 8. The sensor group 12 is connected to a corresponding MCU and a wireless module.

[0038] When in use, the corresponding electrical components are installed inside the housing 8. Then, the personnel install the housing 8 in the corresponding position. When in use, the retractable negative pressure assembly pulls the door 1 closed through the connecting rope until the latch 9 is inserted into the housing 8. Then, the electric suction door assembly drives the latch 61 to rotate through the lock cylinder 62 and the lock body 64. The latch 61 rotates and hooks the latch 9 and gradually tightens the door 1 so that the door 1 fits against the housing 8 and makes contact and seal. When the door 1 is fitted and sealed, the retractable negative pressure assembly no longer retracts the connecting rope and draws out the air in the inner cavity of the housing 8 to form negative pressure.

[0039] When someone maliciously damages the enclosure 8 or the negative pressure inside the enclosure 8 changes rapidly, the sensor group 12 detects the change in negative pressure, and the MCU transmits an alarm signal to the outside through the wireless module based on the data change.

[0040] When it is necessary to open, after reading the card with the NFC card reader, the electric suction door assembly controls the lock hook 61 to reset, the sealing block 68 to reset elastically, and the vent to open. At this time, the cabinet door 1 can be opened, and personnel can pull the cabinet door 1 to open it.

[0041] When the power is completely cut off, personnel can insert the key into the lock body 64. At this time, the sealing block 68 will elastically reset and drive the lock hook 61 to rotate, thereby unlocking. When the power is restored, the electric suction door assembly will reset and drive the lock cylinder 62 to lock the lock body 64.

[0042] It should be noted that the locking structure of lock cylinder 62 can be the same as that of a conventional padlock lock cylinder 62.

[0043] It should be noted that negative pressure is used to make the door 1 fit tightly against the box body 8, thereby ensuring that the door 1 is closed tightly.

[0044] In this embodiment, the electric suction door assembly includes an electric suction door box 6 sealed and fixed inside the housing 8, a worm gear 66 rotatably disposed inside the electric suction door box 6, and a locking motor 67 that drives the worm gear 66. The electric suction door box 6 is provided with a worm wheel 65 that cooperates with the worm gear 66, and the lock cylinder 62 is disposed on the worm wheel 65.

[0045] In use, the locking motor 67 drives the worm gear 66 and worm wheel 65, and the lock cylinder 62 and lock body 64 drive the lock hook 61 to rotate. When locked, the self-locking mechanism of the worm wheel 65 and worm gear 66 achieves locking and ensures tightness.

[0046] It should be noted that the electric suction door box 6 is used to seal the inner wall of the box body 8 to avoid the problem of poor sealing of the box body 8 due to the connection between the worm gear 65 and the lock cylinder 62.

[0047] In this embodiment, a sliding cavity is provided on the side wall of the box body 8, and the sliding cavity is connected to the outside. The vent is opened on the side of the sliding cavity near the inside of the box body 8. The sealing block 68 is slidably connected to the sliding cavity, and the sealing block 68 is connected to a spring 69 fixed in the sliding cavity.

[0048] When in use, when the lock hook 61 locks the latch 9, the sealing block 68 compresses the spring 69 so that when unlocking, the spring 69 can push the sealing block 68 to move so that the vent hole is opened, and when the power is off, the lock hook 61 can be reset after the key is inserted into the lock cylinder 62.

[0049] In this embodiment, the lock hook 61 is integrally formed with a hook connector 611 and the contact surface between the hook connector 611 and the lock buckle 9 is an arc-shaped surface. The two ends of the arc-shaped surface are respectively located on one side near the axis of the lock hook 61 and on the side away from the axis of the lock hook 61, so that after the arc-shaped surface rotates around the axis of the lock hook 61, the lock buckle 9 can drive the box door 1 to contact and seal with the box body 8.

[0050] The locking hook 61 has a limiting part 612 that connects to the arc-shaped surface. The limiting part 612 is an arc-shaped surface with the axis of the locking hook 61 as the center.

[0051] When in use, as the hook 61 rotates, the end of the hook 611 is inserted into the latch 9, and the arc surface contacts the latch 9. Then the hook 61 continues to rotate, and the latch 9 gradually moves with the arc surface and drives the door 1 to contact the sealed box 8. Then the hook 61 enters the limiting part 612 to limit the latch 9 and prevent slippage.

[0052] In this embodiment, a placement slot is provided inside the housing 8, and the winding negative pressure assembly is located in the placement slot. A cover plate 11 is fixed on the opening side of the placement slot. The cover plate 11 has a notch for the connecting rope to pass through. The winding negative pressure assembly includes a drive motor 3 fixed to the placement slot and a winding wheel 5 rotatably connected inside the placement slot. A negative pressure extraction assembly connected to the placement slot is driven on one side of the drive motor 3. The negative pressure extraction assembly connects the internal chamber of the housing 8 and the outside of the housing 8. The winding wheel 5 is driven by the drive motor 3 through a transmission mechanism. When the housing door 1 contacts the sealed housing 8, the transmission mechanism no longer drives the winding wheel 5.

[0053] When in use, the drive motor 3 works and drives the winding wheel 5 to wind up the connecting rope through the transmission mechanism. At this time, the negative pressure extraction component normally extracts air. When the door 1 drives the latch 9 to insert into the box 8, the locking hook 61 drives the door 1 to move through the latch 9, so that the transmission mechanism is no longer driven by the winding wheel 5. At this time, the negative pressure extraction component continues to extract air from the box 8 until the required negative pressure is reached.

[0054] When it is necessary to open, the locking hook 61 no longer locks the latch 9, and the box body 8 draws air through the vent so that the box door 1 can be opened. Then, the personnel can open the box door 1. When it is opened, the box door 1 drives the drive motor 3 to rotate normally through the transmission mechanism.

[0055] It should be noted that a storage groove 63 is provided on the outer circumference side of the locking hook 61, and the connecting rope is connected to the storage groove 63 and enters the storage groove 63 when the locking hook 61 rotates.

[0056] In this embodiment, the negative pressure extraction assembly includes a negative pressure cylinder 2 fixed in the placement groove, a reciprocating screw 23 rotatably connected inside the negative pressure cylinder 2, and a negative pressure piston 21 cooperating with the reciprocating screw 23. The reciprocating screw 23 is fitted with a sealing sleeve 22, which is connected to the negative pressure piston 21 and the inner wall of the negative pressure cylinder 2. The negative pressure cylinder 2 is unidirectionally connected to the chamber of the box body 8 and unidirectionally connected to the outside of the box body 8.

[0057] In use, the reciprocating screw 23 drives the negative pressure piston 21 to move back to the reset position. The sealing sleeve 22 prevents the two ends of the negative pressure piston 21 from being connected. The negative pressure cylinder 2 with one-way connection forms an air pump structure, and the gas is extracted after the negative pressure piston 21 moves back to the reset position.

[0058] It should be noted that the left end of the negative pressure cylinder 2 is connected to the outside of the box 8 and the chamber of the box 8 in one direction. The right end of the negative pressure cylinder 2 has an opening to ensure that the air pressure on the other side of the negative pressure piston 21 is normal, thus ensuring the normal displacement of the negative pressure piston 21.

[0059] In this embodiment, the transmission mechanism includes a transmission box 4 sealed and fixed inside the housing 8, a transmission pulley 41 rotatably connected inside the transmission box 4, a meshing gear disc 45 coaxially fixed with the take-up reel 5, and a meshing gear cylinder 46 meshing with the meshing gear disc 45. There are two transmission pulleys 41 and they are driven by a transmission belt. One of the transmission pulleys 41 is driven by the drive motor 3 through a bevel gear set, and the other transmission pulley 41 is slidably connected to a transmission key barrel 44 through a key shaft. The transmission key barrel 44 is connected to the transmission pulley 41 through a spring piece 43.

[0060] A downward pressing protrusion 42 is inserted between the transmission key barrel 44 and the transmission pulley 41. One end of the downward pressing protrusion 42 extends out of the transmission box 4 and is elastically connected inside the transmission box 4. A contact ring is rotatably connected to the side of the transmission key barrel 44 near the downward pressing protrusion 42. The contact ring contacts the downward pressing protrusion 42. The transmission pulley 41 can also contact the downward pressing protrusion 42 through the corresponding contact ring.

[0061] The meshing gear cylinder 46 is keyed to the transmission key barrel 44, and the meshing gear cylinder 46 and the transmission key barrel 44 are elastically connected.

[0062] It should be noted that the side of the pressing rod 42 facing the transmission key barrel 44 is provided with a circular protrusion, and in order to ensure that the contact ring and the circular protrusion can make smooth contact, a corresponding chamfer or bevel is provided between the circular protrusion and the side of the pressing rod 42.

[0063] When in use, the downward pressing protrusion 42 extends out of the transmission box 4. At this time, the circular protrusion contacts the contact ring on the transmission key barrel 44, and the meshing gear cylinder 46 meshes with the meshing gear disc 45. This causes the drive motor 3 to drive the winding wheel 5 to rotate through the transmission pulley 41, transmission key barrel 44, meshing gear cylinder 46, and meshing gear disc 45. When the box door 1 is completely locked by the locking hook 61 to the point that the box door 1 contacts and seals the box body 8, the downward pressing protrusion 42 moves down to the point where the circular protrusion no longer contacts the contact ring. At this time, the transmission key barrel 44 elastically resets, and the meshing gear cylinder 46 disengages from the meshing gear disc 45.

[0064] It should be noted that the elastic connection between the meshing gear cylinder 46 and the transmission key cylinder 44 provides a buffer when the meshing gear cylinder 46 and the meshing gear disc 45 cannot mesh, and they mesh after alignment, thereby ensuring transmission.

[0065] In this embodiment, a locking opening 7 is provided on the side of the box body 8, and the locking buckle 9 is inserted into the box body 8 through the locking opening 7.

[0066] In this embodiment, a sealing layer 10 is provided on the side of the door 1 to seal against the box body 8.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
