DETAILED DESCRIPTION

[0017] 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.

[0018] An embodiment of the present invention provides an anti-electricity theft device, comprising: Monitoring equipment, used to monitor the inside of the meter box and control whether it is turned on or off through the configured switch unit; A sliding positioning rod is installed on the inner wall of the electric meter box; A movable block slidably arranged on the sliding positioning rod; A spring member is sleeved between the limit block provided at one end of the sliding positioning rod and the movable block; A trigger mechanism is arranged on the door of the electric meter box; The switch unit is configured on the movable block; When the box door is closed, the trigger mechanism causes the movable block to compress the spring member so that the switch unit cannot contact the contact unit set at the preset first position; When the box door is opened, the spring member pushes the movable block to slide, so that the contact unit contacts the switch unit, and the monitoring device is controlled to work.

[0019] When this embodiment is implemented, see Figure 1 , is a schematic structural diagram of an anti-electricity theft device provided in an embodiment of the present invention, wherein the anti-electricity theft device is installed inside an electric meter box 1 .

[0020] It includes a monitoring device 6, which is arranged inside the meter box and is used to monitor the location of the meter inside the meter box.

[0021] A sliding positioning rod 7 is also installed inside the electric meter box 1. A movable block 15 is slidably arranged on the sliding positioning rod 7.

[0022] It should be noted that, in the embodiment Figure 1 In the embodiment, the number of the sliding positioning rods is two, but in actual application, the number of the sliding positioning rod can be one.

[0023] The monitoring device 6 is controlled by the switch unit 13 configured in the movable block 15 to be turned on or off.

[0024] A spring member 9 is sleeved between a limit block 8 provided at one end of the sliding positioning rod 7 and the movable block 15; The spring member 9 can generate a pushing force in a direction relative to the limiting block 8 to push the movable block 15 so that the movable block 15 contacts the contact unit 5 set at the preset first position.

[0025] It should be noted that the diameter of the hole of the movable block on the sliding positioning rod is smaller than the diameter of the spring member, so that the spring member can push the movable block.

[0026] It should be noted that the first position where the contact unit 5 is set should be within the range within which the switch unit can move when the elastic potential energy of the spring member pushes the movable block to move.

[0027] When no external force interference is generated, the spring member can push the movable block to slide under the action of the elastic potential energy, so that the contact unit contacts the switch unit and controls the monitoring device to work.

[0028] It should be noted that after the contact unit and the switch unit come into contact, there are many ways to generate a switch signal, such as a contact conduction electrical signal method, a contact button trigger method, and a magnetic signal recognition method.

[0029] Specifically, the box door 20 installed in the meter box is provided with a trigger mechanism 30 .

[0030] The trigger mechanism 30 can generate a force on the movable block. When the box door is closed, the trigger mechanism 30 generates a force to cause the movable block to compress the spring member so that the switch unit cannot contact the contact unit set at the preset first position. At this time, the monitoring device does not work.

[0031] When the box door is opened, the action force of the trigger structure disappears or cannot counteract the pushing force of the spring member, and the spring member pushes the movable block to slide, so that the contact unit contacts the switch unit, and controls the monitoring device to work.

[0032] It should be noted that the trigger mechanism can use a variety of triggering methods to trigger the door to open and close. For example, the spring member is directly pushed by a mechanical member, or the spring member is pushed by an electrically triggered corresponding mechanism, or a magnetic member generates a corresponding driving force.

[0033] The monitoring device collects image data of the corresponding position, and specifically a camera can be used as the monitoring device.

[0034] The camera collects facial images of power workers, including static images and dynamic images, detects the faces of the collected facial images, and extracts the face area of ​​the person who opens the distribution box on site. The facial image is preprocessed by enhancement, denoising, graying, etc. to improve the image quality, and the face recognition algorithm that extracts facial features extracts features from the preprocessed facial image. The extracted features include facial contours, geometric shapes of facial organs, facial texture information, etc. These features can reflect the uniqueness of the face and provide a reliable basis for subsequent identity recognition. The extracted facial features are compared with the facial features of the power workers stored in the database, and the identity of the power workers is confirmed through face comparison. During the comparison process, if the comparison results are consistent, the identity is confirmed; if the comparison results are inconsistent, a warning is issued to indicate that the identity recognition has failed.

[0035] The anti-electricity theft device provided in the present application does not execute the monitoring process and consumes no energy when the door is closed. After the door is opened, the monitoring function of the monitoring device is automatically triggered. Moreover, the monitoring function of the monitoring device can be activated completely by mechanical mechanisms, with more stable performance, avoiding the situation where the existing sensor triggering and electrical triggering are easily affected by external interference and lead to trigger failure.

[0036] In another embodiment provided by the present invention, the number of the sliding positioning rods is at least 2, and all the sliding positioning rods are arranged in parallel; See also Figure 1 In the embodiment, the number of the sliding positioning rods is 2, all of which are arranged horizontally. In other embodiments, the arrangement direction of the sliding positioning rods can be adjusted according to actual application needs.

[0037] The movable block is provided with holes corresponding to the number and position of the sliding positioning rods, and the corresponding sliding positioning rods pass through them respectively.

[0038] By connecting a plurality of sliding positioning rods with corresponding holes on the movable block, the stability of the movable block during movement is ensured, the stability of the active circuit of the switch unit on the movable block under the door opening and closing condition is improved, and the stability of the monitoring equipment operation is ensured.

[0039] In another embodiment provided by the present invention, the trigger mechanism 30 uses magnetic force to trigger the monitoring device, specifically: The trigger mechanism 30 includes a first magnet 12 and a second magnet 3 .

[0040] See also Figure 2 , is another schematic diagram of the structure of the anti-electricity-theft device provided by an embodiment of the present invention. A first magnet 12 is also provided on the movable block 15 of the anti-electricity-theft device.

[0041] The limit block limits the moving distance of the movable block, thereby preventing the second magnet from directly contacting the first magnet.

[0042] See also Figure 3 , is a schematic diagram of the box door structure of the anti-electricity theft device provided in an embodiment of the present invention. A second magnet 3 is installed at a preset position on the box door 20 through a mounting seat 2.

[0043] When the door is closed, the first magnet and the second magnet are close to each other. At this time, the force generated between the two magnets is strong, which can compress the spring member with a driving force, and the switch unit on the movable block cannot contact the set contact unit; When the door is closed, the first magnet and the second magnet are close to each other. At this time, the force generated between the two magnets is weak, and the spring member pushes the movable block to slide, so that the contact unit contacts the switch unit to control the operation of the monitoring device.

[0044] It should be noted that the magnetic properties of the first magnet and the second magnet are determined according to the specific installation method of the anti-electricity theft device in the box.

[0045] In another embodiment provided by the present invention, when the spring member is sleeved between the limit block provided at one end of the sliding positioning rod close to the box door and the movable block, the spring member is located between the second magnet and the first magnet. In order to counteract the pushing force of the spring member on the movable block, an attractive force needs to be generated between the first magnet and the second magnet, that is, the first magnet and the second magnet are opposite-polarity magnets.

[0046] When the door body is installed on one side of the limit block of the sliding positioning rod, the first magnet and the second magnet are set as magnets of opposite polarity.

[0047] In another embodiment provided by the present invention, when the spring member is sleeved between the limit block set at one end of the sliding positioning rod away from the box door and the movable block, the first magnet is located between the spring member and the second magnet. In order to counteract the driving force of the spring member on the movable block, a driving force needs to be generated between the first magnet and the second magnet, that is, the first magnet and the second magnet are magnets of the same polarity.

[0048] When the door body is installed on the side opposite to the limiting block of the sliding positioning rod, the first magnet and the second magnet are arranged to be magnets of the same polarity.

[0049] In another embodiment provided by the present invention, The switch unit 13 is a power plug of the monitoring device.

[0050] The contact unit 5 is a power supply socket, which is connected to a power source via a wire.

[0051] When the box door is opened, the power plug is inserted into the power socket to supply power and the monitoring equipment works. When the box door is closed, the movable block is moved under the action of magnetic force, so that the power plug is pulled out, the power plug is separated from the power socket, and the spring part is compressed to cut off the power, which is beneficial to saving electricity and preventing waste of electricity.

[0052] In another embodiment provided by the present invention, a connecting ear 10 is provided on the power socket; The connecting ear 10 is fixedly connected to the threaded hole provided on the sliding positioning rod 7 through a bolt 11 .

[0053] It should be noted that the power socket is provided with a plurality of connection ears, which are respectively fixedly connected with a plurality of sliding positioning rods to ensure the stability of the power socket installation. The power socket can be disassembled by using bolts for easy replacement.

[0054] In another embodiment provided by the present invention, see Figure 4 , is another structural diagram of the anti-electricity theft device provided by an embodiment of the present invention. A buffer pad 16 is arranged on the side of the power plug of the switch unit 13 close to the power socket.

[0055] The buffer pad provided plays a buffering role when the power plug is connected to the power socket to prevent damage caused by collision.

[0056] In yet another embodiment provided by the present invention, the device further comprises a wireless transmission unit; The monitoring device transmits the monitoring signal via a wireless transmission unit.

[0057] In order to connect with the receiving device and display the monitored image, the receiving device is the database in the computer background. The image is compared with the face database of power workers to confirm that it is a power worker.

[0058] When electricity theft occurs, an alarm can be triggered to improve safety.

[0059] In another embodiment provided by the present invention, a lubricating medium is applied to the sliding positioning rod to reduce the sliding resistance of the movable block on the sliding positioning block, avoid jamming, and improve the working stability of the mechanical device.

[0060] It should be noted that a sliding roller may be provided at the contact point between the movable block and the sliding positioning rod to reduce the sliding friction.

[0061] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
