[0001] The present invention belongs to the technical field of intelligent detection devices, and in particular relates to a meter box opening alarm device based on image acquisition. Background Art

[0002] The meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. It consists of an energy meter, voltage transformers for measurement, and current transformers. Meter boxes are widely used in commercial housing to count the amount of electricity used by each household. In order to prevent non-staff from illegally modifying meter box parameters, stealing valuable electronic components in the meter box, and stealing electricity, the meter box needs to take certain anti-theft measures.

[0010] Furthermore, the side wall of the metering box body corresponding to the arc-shaped rack is hollow, and the three shielding horizontal plates are coaxially fixedly connected with an adjusting gear. The adjusting gear is located in the side wall of the metering box body corresponding to the side, and a screw sleeve is threaded on the threaded rod, and a connecting bracket is fixedly connected to one side of the screw sleeve.

[0011] Furthermore, an adjusting tooth plate is fixedly connected to the connecting bracket, and the adjusting tooth plate is meshed with three adjusting gears.

[0013] Compared with the existing technology, the advantages of the present invention are:

[0014] 1. The present invention is provided with an anti-meter adjustment mechanism. When non-staff members open the box door, the arc-shaped rack on the box door will rotate, and at this time the matching gear and the connecting gear will mesh with the arc-shaped rack. The rotation of the arc-shaped rack will drive the two gears to rotate, thereby causing the screw sleeve on the threaded rod and the connecting bracket to move a certain distance. The adjusting tooth plate fixedly connected to the connecting bracket will cause the three adjusting gears to rotate about ninety degrees. At this time, the three shielding horizontal plates will block the operable area of the electronic components on the main mounting plate. At the same time, in order to ensure the completeness of the shielding, the adjusting tooth plate moves downward, through the connection of the linkage shaft. At this time, the U-shaped connecting frame and the main mounting plate as a whole will move to the side of the shielding horizontal plate under the traction of the sliding arm, so that the shielding horizontal plate is close to the electronic components on the main mounting plate, making it impossible for illegal openers to change the parameters of electronic components such as the electric energy meter.

[0015] 2. The present invention is provided with an anti-theft bell and an anti-theft spray starting mechanism. When non-staff open the box door, the arc-shaped rack will drive the mating gear meshing with it to rotate, and the sound brush and the reciprocating threaded rod coaxially fixedly connected to the mating gear will rotate. The sound brush cooperates with the sound drum to emit an alarm sound to alert the property or management personnel. The rotation of the reciprocating threaded rod causes the piston plate threadedly connected to it to reciprocate, thereby squeezing out the pepper water in the pressurized shell and finally spraying it out from the early warning spray port, thereby driving away illegal box openers and avoiding further expansion of losses.

[0016] 3. The present invention is provided with an anti-theft electric shock mechanism. When an illegal person opens the box and removes and steals valuable electronic components on the main installation board, the overall weight of the main installation board will decrease, the buffer spring and the telescopic rod will shrink relatively, and the annular slider on the sliding rheostat will change position, thereby changing the parameters of the sliding rheostat. An LM311 voltage comparator is provided in the wireless alarm port, and the LM311 voltage comparator is electrically connected to the sliding rheostat. When the resistance value of the sliding rheostat changes, the wireless alarm port will remotely alarm, and the early warning cooperation box as a whole will be conductive, thereby electric shocking and driving away the illegal person who opens the box. The current of the early warning cooperation box is within the safe range for the human body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0025] like Figures 1-6 As shown, a meter box opening alarm device based on image acquisition includes:

[0026] The metering box body 1 is hinged with a box door 2, the box door 2 is fixedly connected to a micro electric telescopic rod 3, the micro electric telescopic rod 3 is fixedly connected to an arc-shaped rack 4, and one side of the metering box body 1 is fixedly connected to an early warning coordination box 5;

[0027] Specifically, a through slot is provided on the side wall of the meter box body 1 corresponding to the position of the motion trajectory of the arc-shaped rack 4. The staff can remotely control the micro-electric telescopic rod 3 and the early warning coordination box 5 through an external program. When the staff opens the meter box body 1 normally, the output end of the micro-electric telescopic rod 3 extends, and the early warning coordination box 5 is powered off, thereby turning off the corresponding anti-theft function in the device;

[0028] An anti-theft bell and an anti-theft spray activation mechanism are provided in the early warning coordination box 5. Three shielding horizontal plates 6 are rotatably connected in the metering box body 1. Sliding shafts 7 are fixedly connected to the inner walls of both sides of the metering box body 1. A U-shaped connecting frame 8 is provided in the metering box body 1. Two sliding sleeves 9 are fixedly connected to both ends of the U-shaped connecting frame 8. The two pairs of sliding sleeves 9 on the U-shaped connecting frame 8 are respectively slidably connected to the sliding shafts 7 on the corresponding side. An anti-theft electric shock mechanism is provided on the output end of the U-shaped connecting frame 8. An anti-meter adjustment mechanism is provided in the side wall of the metering box body 1 near the hinged position of the box door 2;

[0029] The anti-theft bell and anti-theft spray activation mechanism includes a No. 2 rotating seat 21 fixedly connected to the early warning matching box 5, and a matching gear 22 is rotatably connected to the No. 2 rotating seat 21. A sound drum 23 and a pressurized shell 24 are fixedly connected to the inner wall of the early warning matching box 5. The matching gear 22 is coaxially fixedly connected to a sound brush 25. The sound drum 23 and the sound brush 25 are matched. A reciprocating threaded rod 26 is coaxially fixedly connected to the bottom of the sound brush 25. A piston plate 27 is slidably connected to the pressurized shell 24. The reciprocating threaded rod 26 penetrates the piston plate 27 and is threadedly connected thereto. A one-way valve is provided on both the output and input ends of the pressurized shell 24. A warning spray port 28 is fixedly connected to the top of the metering box body 1, and the output end of the pressurized shell 24 is connected to the warning spray port 28;

[0030] Specifically, when an illegal person opens the box door 2, the arc-shaped rack 4 on the box door 2 will move toward the side of the warning matching box 5. At this time, the arc-shaped rack 4 will cause the matching gear 22 engaged therewith to rotate, and the sound brush 25 and the reciprocating threaded rod 26 coaxially fixedly connected to the matching gear 22 will rotate. When the sound brush 25 rotates, the sound drum 23 matched therewith will vibrate and emit an alarm sound, thereby alerting the attached security personnel. At the same time, the rotation of the reciprocating threaded rod 26 will cause the piston plate 27 threadedly connected thereto to reciprocate up and down in the pressurized shell 24, and the pressurized shell 2 The input end of the pressure relief valve 24 needs to be connected to an external stable source of pepper spray. When the piston plate 27 moves upward, the external pepper spray can be pumped into the pressurized housing 24. When the piston plate 27 moves downward, the pepper spray in the pressurized housing 24 will be pumped out and eventually sprayed out at the warning spray port 28, thereby driving away illegal box openers. It should be noted that the flow direction of the one-way valve on the output end of the pressurized housing 24 is from the inside of the pressurized housing 24 to the outside of the pressurized housing 24, and the flow direction of the one-way valve on the input end of the pressurized housing 24 is from the outside of the pressurized housing 24 to the inside of the pressurized housing 24.

A buffer spring 33 is provided on the outer sleeve of the telescopic rod 31, and the two ends of the buffer spring 33 are respectively fixedly connected to the U-shaped connecting frame 8 and the main mounting plate 32. A conductive rod is fixedly connected to the U-shaped connecting frame 8, a sliding rheostat 34 is fixedly connected to the main mounting plate 32, and the conductive rod is fixedly connected to the annular slide on the sliding rheostat 34. A wireless alarm port 35 is fixedly connected to the top of the meter box body 1, and an alarm light 36 is fixedly connected to the wireless alarm port 35;

[0032] Specifically, the purpose of setting the anti-theft electric shock mechanism is that when an illegal box opener wants to steal the electronic components on the main installation plate 32 in the meter box body 1 after opening the box, the meter box body 1 can be electrified to perform an electric shock on the illegal thief by taking advantage of the overall metal conductivity of the meter box body 1. When the electronic components on the main installation plate 32 are taken away, the overall weight of the main installation plate 32 will be greatly reduced, the buffer spring 33 and the telescopic rod 31 will shrink as a whole, and the annular slider on the sliding rheostat 34 will slide upward a certain distance through the connection of the conductive rod, so that the resistance value of the sliding rheostat 34 will change. An LM311 voltage comparator is provided in the wireless alarm port 35, and the LM311 voltage comparator is electrically connected to the sliding rheostat 34. When the resistance value of the sliding rheostat 34 changes, the wireless alarm port 35 will remotely alarm, and the early warning cooperation box 5 as a whole will be conductive, thereby performing an electric shock to drive away the illegal box opener, and the current of the early warning cooperation box 5 is within the safe range for human body.

[0033] The anti-meter adjustment mechanism includes a No. 1 rotating seat 41 fixedly connected to the inner wall of the meter box body 1, a threaded rod 42 is rotatably connected to the No. 1 rotating seat 41, a connecting gear 43 is coaxially fixedly connected to the top of the threaded rod 42, a matching rotating seat 44 is rotatably connected to the connecting gear 43, and the other end of the matching rotating seat 44 is fixedly connected to the meter box body 1. The side wall of the meter box body 1 corresponding to the side of the arc-shaped rack 4 is hollow, and three shielding horizontal plates 6 are coaxially fixedly connected to the adjusting gear 45. The adjusting gear 45 is located inside the side wall of the corresponding side of the meter box body 1 , a screw sleeve 46 is threadedly connected to the threaded rod 42, and a connecting bracket 47 is fixedly connected to one side of the screw sleeve 46. An adjusting tooth plate 48 is fixedly connected to the connecting bracket 47. The adjusting tooth plate 48 is meshed with the three adjusting gears 45. A sliding arm 49 is fixedly connected to the side wall of the U-shaped connecting frame 8 on the side corresponding to the arc-shaped rack 4. A transverse slide rod 410 is fixedly connected to the side wall of the corresponding side of the metering box body 1. The sliding arm 49 is slidably connected to the transverse slide rod 410, and a linkage shaft 411 is rotatably connected between the sliding arm 49 and the adjusting tooth plate 48;

[0034] Specifically, the anti-meter adjustment mechanism is set to prevent illegal personnel from illegally opening the box to operate the electronic components in the meter box body 1. When the illegal personnel open the box body door 2, the arc rack 4 on the box body door 2 will rotate, and at this time the matching gear 22 and the connecting gear 43 will mesh with the arc rack 4. The rotation of the arc rack 4 will drive the two gears to rotate, so that the screw sleeve 46 on the threaded rod 42 and the connecting bracket 47 will move a certain distance, and the adjusting tooth plate 48 fixedly connected to the connecting bracket 47 will make the three adjustment The segment gear 45 rotates about ninety degrees. At this time, the three shielding horizontal plates 6 will block the operable area of the electronic components on the main installation plate 32. At the same time, in order to ensure the completeness of the shielding, the gear plate 48 is adjusted to move downward. Through the connection of the linkage shaft 411, the U-shaped connecting frame 8 and the main installation plate 32 as a whole will be pulled toward the side of the shielding horizontal plate 6 by the sliding arm 49, so that the shielding horizontal plate 6 is close to the electronic components on the main installation plate 32, making it impossible for illegal unpacking personnel to change the parameters of electronic components such as the electricity meter.

[0035] The working principle of the present invention is as follows:

[0036] A through slot is provided on the side wall of the meter box body 1, corresponding to the position of the motion trajectory of the arc-shaped rack 4. The staff can remotely control the micro-electric telescopic rod 3 and the early warning coordination box 5 through an external program. When the staff opens the meter box body 1 normally, the output end of the micro-electric telescopic rod 3 extends, and the early warning coordination box 5 is powered off, thereby turning off the corresponding anti-theft function in the device;

[0037] When an illegal person opens the box door 2, the arc-shaped rack 4 on the box door 2 will move toward the side of the early warning matching box 5. At this time, the arc-shaped rack 4 will cause the matching gear 22 meshing with it to rotate, and the sound brush 25 and the reciprocating threaded rod 26 coaxially fixedly connected to the matching gear 22 will rotate. When the sound brush 25 rotates, the matching sound drum 23 will vibrate and emit an alarm sound, thereby alerting the attached security personnel. At the same time, the rotation of the reciprocating threaded rod 26 will cause the piston plate 27 threadedly connected to it to reciprocate up and down in the pressurized shell 24, and the pressurized shell 24 The input end needs to be connected to an external stable source of pepper spray. When the piston plate 27 moves upward, the external pepper spray can be pumped into the pressurized shell 24. When the piston plate 27 moves downward, the pepper spray in the pressurized shell 24 will be pumped out and eventually sprayed out at the warning spray port 28, thereby driving away illegal box openers. It should be noted that the flow direction of the one-way valve on the output end of the pressurized shell 24 is from the inside of the pressurized shell 24 to the outside of the pressurized shell 24, and the flow direction of the one-way valve on the input end of the pressurized shell 24 is from the outside of the pressurized shell 24 to the inside of the pressurized shell 24.

[0038] The purpose of setting the anti-theft electric shock mechanism is that when an illegal box opener wants to steal the electronic components on the main installation plate 32 in the meter box body 1 after opening the box, the metal conductivity of the meter box body 1 can be used to electrically shock the illegal thief by energizing the meter box body 1. When the electronic components on the main installation plate 32 are taken away, the overall weight of the main installation plate 32 will be greatly reduced, the buffer spring 33 and the telescopic rod 31 will shrink as a whole, and the annular slider on the sliding rheostat 34 will slide upward a certain distance through the connection of the conductive rod, so that the resistance value of the sliding rheostat 34 will change. An LM311 voltage comparator is provided in the wireless alarm port 35, and the LM311 voltage comparator is electrically connected to the sliding rheostat 34. When the resistance value of the sliding rheostat 34 changes, the wireless alarm port 35 will remotely alarm, and the early warning cooperation box 5 as a whole will be conductive, thereby electrically shocking the illegal box opener and driving him away. The current of the early warning cooperation box 5 is within the safe range for the human body.

[0039] The anti-meter adjustment mechanism is set to prevent illegal personnel from illegally operating the electronic components in the meter box body 1. When the illegal personnel open the box door 2, the arc rack 4 on the box door 2 will rotate, and at this time the matching gear 22 and the connecting gear 43 will mesh with the arc rack 4. The rotation of the arc rack 4 will drive the two gears to rotate, so that the screw sleeve 46 on the threaded rod 42 and the connecting bracket 47 will move a certain distance, and the adjusting tooth plate 48 fixedly connected to the connecting bracket 47 will make the three adjusting gears rotate. The wheel 45 rotates about ninety degrees. At this time, the three shielding horizontal plates 6 will block the operable area of the electronic components on the main installation plate 32. At the same time, in order to ensure the completeness of the shielding, the tooth plate 48 is adjusted to move downward. Through the connection of the linkage shaft 411, the U-shaped connecting frame 8 and the main installation plate 32 as a whole will be pulled toward the side of the shielding horizontal plate 6 by the sliding arm 49, so that the shielding horizontal plate 6 is close to the electronic components on the main installation plate 32, making it impossible for illegal unpacking personnel to change the parameters of electronic components such as the electricity meter.
