Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more specifically to an online monitoring system for an anti-theft metering distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] In the current technology, as an indispensable electrical component in production and daily life, the anti-theft protection of distribution cabinets has not received much attention. Theft of electrical equipment in distribution cabinets can not only cause power outages but may also harm the thieves. Upgrading the anti-theft features of distribution cabinets will not only improve the stability of power supply lines but also reduce accidental injuries. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: an online monitoring system for an anti-theft metering distribution cabinet, comprising a sensing unit, a triggering unit, and an alarm unit. The sensing unit is used to determine whether the theft method employed by the thief is violent or non-violent. The triggering unit is used to trigger the alarm and monitoring, simultaneously providing external protection. The alarm unit includes an anti-theft cabinet for adjusting the position of the camera and the alarm. The anti-theft cabinet includes a cabinet, with a range adjustment device installed above the inner wall of the cabinet. An alarm device is installed below the range adjustment device. An anti-violent device is installed on one side of the alarm device, and an anti-pry lock device is installed on the other side of the alarm device. A semi-circular baffle is installed between the anti-violent device and the anti-pry lock device. The lower surface of the semi-circular baffle... The cabinet is rotatably connected to a base, and a guide rod is fixedly connected to the upper surface of the base. A first spring is provided on the outside of the guide rod. A cabinet door is rotatably connected to the outer surface of the cabinet. The range adjustment device includes a camera, a connecting rod is fixedly connected to the upper surface of the camera, and a first rack is fixedly connected to the upper surface of the connecting rod. A gear is driven through the tooth surface of the first rack, and a second rack is driven through the tooth surface of the gear. A helical spring is fixedly connected to the outer surface of the second rack, and a semi-circular baffle is fixedly connected to the inner surface of the helical spring. Before the anti-theft system is triggered, the camera installed at the rear can detect the internal condition of the distribution cabinet. When the anti-theft system is triggered, the camera, which is pulled forward, moves to the front and can detect the situation around the cabinet door, performing a wider range of detection.

[0005] Preferably, the alarm device includes a fixed rod, the upper surface of which is fixedly connected to the inner wall of the cabinet. A fixed base is fixedly connected to the outer surface of the semi-circular baffle, and a light is fixedly connected to the upper surface of the fixed base. A focusing plate is fixedly connected to the outer surface of the light, and an alarm is installed on one side of the focusing plate. The outer surface of the alarm is fixedly connected to the upper surface of the fixed base, and a loudspeaker is fixedly connected to the outer surface of the alarm. A transparent plate is fixedly connected to the outer surface of the fixed base, and a battery is installed above the transparent plate. The outer surface of the battery is fixedly connected to the outer surface of the semi-circular baffle. Because the movement of the semi-circular baffle faces the cabinet door, the alarm and light have a deterrent effect on thieves when triggered.

[0006] Preferably, a trapezoidal plate is fixedly connected to the outer surface of the fixing rod, and a lifting rod is provided on the same plane of the trapezoidal plate. The outer surface of the trapezoidal plate is in contact with the outer surface of the lifting rod. A hammer block is slidably connected to the outer surface of the lifting rod. The outer surface of the hammer block is rotatably connected to the inner surface of the fixing base. A limit block is fixedly connected to the outer surface of the fixing base, and a strike-receiving slider is provided between the limit blocks. A second spring is fixedly connected to the outer surface of the strike-receiving slider, and a rotating rod is fixedly connected to the outer surface of the second spring. The outer surface of the rotating rod rotates with the inner surface of the fixing base. The alarm and the light are rotatably connected to a switch on their outer surfaces. A magnet is located below the fixed base, and a semi-circular baffle is fixedly connected to the outer surface of the magnet. As the semi-circular baffle is rotated, the lifting rod on the trapezoidal plate moves away from the support, causing the raised hammer block to fall due to gravity. The falling hammer block strikes the impacted slider. Due to the force and a slight centrifugal force, the impacted slider moves relative to the position of the semi-circular baffle. During this process, the impacted slider passes through the switch, turning on the alarm and the light. The impacted slider is attracted by the magnet at the end point.

[0007] Preferably, the anti-violence device includes a fixed block, a connecting bracket rotatably connected to the inner surface of the fixed block, a sliding block rotatably connected to the outer surface of the connecting bracket, a sliding bracket slidably connected to the inner surface of the sliding block, a positioning rod rotatably connected to the inner surface of the sliding bracket, a displacement limiting block slidably connected to the outer surface of the positioning rod, and a pressing rod slidably connected to the inner surface of the displacement limiting block. When the positioning rod moves outside the normal range, it will exert downward pressure on the pressing rod, and the pressing rod will push the pressing cylinder downward.

[0008] Preferably, a pressing cylinder is fixedly connected to the outer surface of the pressing rod, a driving rod is fixedly connected to the outer surface of the pressing cylinder, a semi-circular baffle is fixedly connected to the outer surface of the driving rod, a compression spring is fixedly connected to the lower surface of the pressing cylinder, a fixing cylinder is provided outside the compression spring, a cabinet is fixedly connected to the outer surface of the fixing cylinder, a displacement limiting block is fixedly connected to the outer surface of the cabinet, and a cabinet door is fixedly connected to the outer surface of the fixing block. The driving rod, blocked by the pressing cylinder, moves along the direction of the guide rod under the tension of the first spring, and at the same time moves the semi-circular baffle forward until it stops moving when it collides with the inner protrusion above the cabinet and the protrusion above the semi-circular baffle, forming a second door as a blocking effect.

[0009] Preferably, a trapezoidal slider is slidably connected to the outer surface of the crossbar, a retainer is slidably connected to the outer surface of the crossbar, an inclined cylinder is slidably connected to the inner surface of the retainer, a third spring is fixedly connected to the outer surface of the inclined cylinder, the outer surface of the third spring is fixedly connected to the surface of the retainer, a cabinet door is fixedly connected to the outer surface of the retainer, a base is fixedly connected to the outer surface of the positioning limiting block, a base is fixedly connected to the lower surface of the slot, and a semi-circular baffle is fixedly connected to the outer surface of the connecting slider. A connecting slider is fixedly connected to the outer surface of the first spring, and a driving rod is also fixedly connected to the outer surface of the first spring. If a thief unlocks the cabinet without damaging the internal structure, he will inevitably pull the cabinet door outward to facilitate theft due to his lack of knowledge of the internal structure and his normal reaction. At this time, the blocking and fixing device of the crossbar and the inclined cylinder will exert an outward pulling force on the crossbar. The crossbar drives the pulling rod to move, and the pulling rod generates a pushing force on the extension block on the connecting slider, forcing the connecting slider to leave the slot. The connecting slider moves along the guide rod under the pull of the first spring, and the semi-circular baffle fixed to the connecting slider is also driven and rotates to the front until it stops moving when it collides with the protrusion inside the cabinet and the protrusion on the top of the semi-circular baffle, thus forming the second door.

[0010] The beneficial effects of this invention are as follows:

[0011] 1. This invention incorporates an anti-violent device that securely connects a fixing block to the cabinet door. A triangular stable structure is formed by a connecting bracket and a sliding bracket. The connecting bracket is connected to the sliding bracket via a sliding block, and the sliding bracket is connected to a displacement limiting block via a positioning rod. The displacement limiting block is fixed to the cabinet. If a thief attempts to forcibly damage the cabinet door, the triangular rod fixed to the cabinet and door will provide reinforcement. If the door is still damaged, the thief will inevitably pull the damaged structure to steal items from the distribution cabinet. The positioning rod, moving outside its normal range, will exert downward pressure on the pressing rod. The pressing rod pushes the pressing cylinder downwards. The rod, blocked by the pressing cylinder, moves along the guide rod under the tension of the first spring, simultaneously moving the semi-circular baffle forward until it collides with the internal protrusion above the cabinet and the protrusion above the semi-circular baffle, thus forming a second door for obstruction.

[0012] 2. This invention, by incorporating an anti-pry lock device, fixes the retainer to the cabinet door surface. In the normally closed state, the trapezoidal cylinder at the front of the crossbar will advance along the inclined cylinder. When the cabinet door is fully closed, the trapezoidal cylinder at the front of the crossbar will pass through the inclined cylinder. This means that if someone pulls the crossbar outwards, the trapezoidal cylinder will block the inclined cylinder. If a thief unlocks the door without damaging the internal structure, due to a lack of understanding of the internal structure and their normal reaction, they will inevitably pull the cabinet door outwards to steal. At this time, the crossbar's blocking retainer and the inclined cylinder will exert an outward pulling force on the crossbar, causing the crossbar to move the pulling rod. The pulling rod then exerts a force on the extension on the connecting slider. The block generates a thrust, forcing the connecting slider to leave the slot. Under the pull of the first spring, the connecting slider moves along the guide rod, and the semi-circular baffle fixed to the connecting slider is also driven, rotating to the front until it stops moving when it collides with the protrusion inside the cabinet and the protrusion above the semi-circular baffle, thus forming the second door. At this time, the pulling rod is blocked by the positioning limiting block, forming a barrier. For personnel familiar with the internal structure, after opening, they only need to push the cabinet door inward, and after the inclined cylinder passes the trapezoidal slider, pull it outward. Because of the shape of the trapezoidal slider, the return state of the retainer allows the inclined cylinder to move along the inclined surface of the trapezoidal slider, thus completing the unlocking.

[0013] 3. This invention, by setting up an alarm device, when the anti-violent device or anti-pry lock device is triggered, the semi-circular baffle is rotated, causing the lifting rod on the trapezoidal plate to move away from the support. This causes the raised hammer block to fall due to gravity. The falling hammer block strikes the impacted slider. Due to the force and a slight centrifugal force, the impacted slider moves relative to the position of the semi-circular baffle. During this process, the impacted slider passes through a switch, turning on the alarm and light. The impacted slider is attracted by a magnet at the end point. At this time, the alarm and light are facing the cabinet door due to the movement of the semi-circular baffle, which has a deterrent effect on thieves.

[0014] 4. This invention uses a range adjustment device to fix a helical spring to the protrusion above the semicircular baffle, with the other end fixed to the second rack. During the movement of the semicircular baffle, after the helical spring reaches its maximum force position, it will drive the second rack to move. Through the meshing gears, the first rack and the second rack move in opposite directions. Since the camera is fixed to the first rack via a connecting rod, before the anti-theft system is triggered, the camera installed at the rear can detect the internal condition of the power distribution cabinet. When the anti-theft system is triggered, the camera, which is pulled forward, moves to the front and can detect the situation around the cabinet door, thus performing a wider range of detection.

The falling hammer block 313 strikes the impacted slider 315. Due to the force and a little centrifugal force, the impacted slider 315 moves relative to the position of the semi-circular baffle 6. During the process, the impacted slider 315 passes through the switch 319, turning on the alarm 34 and the lamp 32. The impacted slider 315 is attracted by the magnet 317 at the end point.

[0027] Example 2: Please refer to Figure 5 - Figure 7 The present invention provides a technical solution: Based on embodiment one, the anti-violence device 4 includes a fixed block 41, a connecting bracket 42 rotatably connected to the inner surface of the fixed block 41, a sliding block 43 rotatably connected to the outer surface of the connecting bracket 42, a sliding bracket 44 slidably connected to the inner surface of the sliding block 43, a positioning rod 45 rotatably connected to the inner surface of the sliding bracket 44, a displacement limiting block 46 slidably connected to the outer surface of the positioning rod 45, and a pressing rod 47 slidably connected to the inner surface of the displacement limiting block 46. When the positioning rod 45 moves outside the normal range, it will exert downward pressure on the pressing rod 47. The pressing rod 47 pushes the pressing cylinder 471 downward. The driving rod 474, blocked by the pressing cylinder 471, moves along the direction of the guide rod 8 under the tension of the first spring 9.

[0028] A pressing cylinder 471 is fixedly connected to the outer surface of the pressing rod 47. A driving rod 474 is fixedly connected to the outer surface of the pressing cylinder 471. A semi-circular baffle 6 is fixedly connected to the outer surface of the driving rod 474. A compression spring 473 is fixedly connected to the lower surface of the pressing cylinder 471.

A displacement limiting block 46 is fixedly connected to the outer surface of the cabinet 1. A cabinet door 10 is fixedly connected to the outer surface of the fixing block 41. The driving rod 474, blocked by the pressing cylinder 471, moves along the direction of the guide rod 8 under the pulling force of the first spring 9, and at the same time moves the semi-circular baffle 6 to the front until it stops moving when it collides with the inner protrusion on the top of the cabinet 1 and the protrusion on the top of the semi-circular baffle 6, forming a second door as a blocking effect.

[0029] The anti-pry lock device 5 includes a slot 51, a connecting slider 52 is slidably connected to the inner surface of the slot 51, an extension block 53 is fixedly connected to the upper surface of the connecting slider 52, a pull rod 54 is provided on one side of the extension block 53, a crossbar 55 is rotatably connected to the outer surface of the pull rod 54, and a positioning limiting block 56 is slidably connected to the outer surface of the crossbar 55. At this time, the pull rod 54 is blocked by the positioning limiting block 56 to form a blockage, which serves as a blocking and hindering effect.

[0030] A trapezoidal slider 551 is slidably connected to the outer surface of the crossbar 55. A retainer 552 is slidably connected to the outer surface of the crossbar 55. An inclined cylinder 553 is slidably connected to the inner surface of the retainer 552. A third spring 554 is fixedly connected to the outer surface of the inclined cylinder 553. The outer surface of the third spring 554 is fixedly connected to the surface of the retainer 552. A cabinet door 10 is fixedly connected to the outer surface of the retainer 552. A base 7 is fixedly connected to the outer surface of the positioning limiting block 56. The base 7 is fixedly connected to the lower surface of the slot 51. A semi-circular slider 52 is fixedly connected to the outer surface of the connecting slider 52. The outer surface of the circular baffle 6 and the first spring 9 is fixedly connected to a connecting slider 52. The outer surface of the first spring 9 is also fixedly connected to a driving rod 474. At this time, the pulling rod 54 is blocked by the positioning limiting block 56, forming a blockage. As a blocking and obstructing effect, for personnel familiar with the internal structure, after opening, they only need to push the cabinet door 10 inward. After the inclined cylinder 553 passes the trapezoidal slider 551, it is pulled outward. Because of the shape of the trapezoidal slider 551, the return state of the fixing device 552 can make the inclined cylinder 553 move along the inclined surface of the trapezoidal slider 551, thus completing the unlocking.

[0031] Working principle:

[0032] In use, by setting up the anti-violent device 4, the fixing block 41 is fixedly connected to the cabinet door 10. A triangular stable structure is formed by the connecting bracket 42 and the sliding bracket 44. The connecting bracket 42 is connected to the sliding bracket 44 via the sliding block 43. The sliding bracket 44 is connected to the displacement limiting block 46 via the positioning rod 45. The displacement limiting block 46 is fixed to the cabinet 1. If a thief attempts to forcibly damage the cabinet door 10, the triangular rod fixed to the cabinet 1 and the cabinet door 10 will provide reinforcement. If it is still damaged... In order to steal items from the power distribution cabinet, the structure will inevitably be damaged. When the positioning rod 45 moves outside the normal range, it will exert downward pressure on the pressing rod 47. The pressing rod 47 pushes the pressing cylinder 471 downward. The driving rod 474, which is blocked by the pressing cylinder 471, moves along the direction of the guide rod 8 under the tension of the first spring 9. At the same time, it drives the semi-circular baffle 6 to move forward until it stops moving when it collides with the protrusion inside the cabinet 1 and the protrusion above the semi-circular baffle 6, forming a second door as a blocking effect.

[0033] In use, by setting the anti-pry lock device 5, the fixing device 552 is fixed to the surface of the cabinet door 10. In the normal closed state, the trapezoidal cylinder at the front end of the crossbar 55 will move along the direction of the inclined cylinder 553. When the cabinet door 10 is fully closed, the trapezoidal cylinder in front of the crossbar 55 will pass through the inclined cylinder 553. When an outsider pulls outward, the trapezoidal cylinder of the crossbar 55 will block the inclined cylinder 553. If a thief unlocks the door without damaging the internal structure, due to a lack of knowledge of the internal structure and normal reaction, he will inevitably pull the cabinet door 10 outward to steal. At this time, the fixing device 552 and the inclined cylinder 553 of the crossbar 55 will exert an outward pulling force on the crossbar 55. The crossbar 55 drives the pulling rod 54 to move. The pulling rod 54 exerts a pulling force on the connecting slider 52. The extension block 53 generates a thrust, forcing the connecting slider 52 to leave the slot 51. Under the pull of the first spring 9, the connecting slider 52 moves along the guide rod 8. The semi-circular baffle 6 fixed to the connecting slider 52 is also driven and rotates to the front until it is stopped by the collision between the internal protrusion above the cabinet 1 and the protrusion above the semi-circular baffle 6, thus forming the second door. At this time, the pulling rod 54 is blocked by the positioning limiting block 56, forming a blockage. As a blocking and obstructing effect, for personnel familiar with the internal structure, after opening, they only need to push the cabinet door 10 inward. After the inclined cylinder 553 passes the trapezoidal slider 551, it is pulled outward. Because of the shape of the trapezoidal slider 551, the retainer 552 can make the inclined cylinder 553 move along the inclined surface of the trapezoidal slider 551 in the return state, thus completing the unlocking.

[0034] In use, by setting the alarm device 3, when the anti-violent device 4 or the anti-pry lock device 5 is triggered, the semi-circular baffle 6 is rotated, causing the lifting rod 312 on the trapezoidal plate 311 to move away from the support, causing the raised hammer block 313 to fall due to gravity. The falling hammer block 313 strikes the impacted slider 315. Due to the force and a little centrifugal force, the impacted slider 315 moves relative to the position of the semi-circular baffle 6. During the process, the impacted slider 315 passes through the switch 319, turning on the alarm 34 and the light 32. The impacted slider 315 is attracted by the magnet 317 at the end point. At this time, the alarm 34 and the light 32 are facing the door of the cabinet 10 due to the movement of the semi-circular baffle 6, which has a deterrent effect on thieves.

[0035] In use, by setting the range adjustment device 2, a spiral spring 23 is fixed on the protrusion above the semicircular baffle 6, and the other end is fixed on the second rack 26. During the movement of the semicircular baffle 6, after the spiral spring 23 reaches the maximum force position, it will drive the second rack 26 to move. Through the meshing gear 25, the first rack 24 and the second rack 26 move in opposite directions. Since the camera 21 is fixed on the first rack 24 through the connecting rod 22, before the anti-theft system is triggered, the camera 21 installed at the rear can detect the internal condition of the power distribution cabinet. When the anti-theft system is triggered, the camera 21, which is pulled forward, moves to the front and can detect the situation around the cabinet door 10, and perform detection in a wider range.

[0036] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
