DETAILED DESCRIPTION

[0031] 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.

[0032] like Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: an anti-electricity theft smart energy meter includes a protection box 1 for installing an energy meter body 24, a box door 2, an alarm 26, a protection component and a protection net.

[0033] The electric energy meter body 24 is mounted on the rear inner wall of the protection box 1 , and a wire hole 25 is provided at the lower end of the protection box 1 to facilitate wiring of the electric energy meter body 24 .

[0034] The box door 2 is rotatably arranged at the front end of the protection box 1. A mechanical lock is arranged between the box door 2 and the protection box 1, and a lock hole 3 is arranged on the box door 2. The mechanical lock is equipped with a key, and the mechanical lock is opened by the key.

[0035] The protection assembly includes a connecting rod 20, a second limiting plate 21 and a first limiting plate 19. The second limiting plate 21 is fixedly connected to one end of the connecting rod 20, and the first limiting plate 19 is fixedly connected to the other end of the connecting rod 20. An embedding groove is provided on the box door 2, and the second limiting plate 21 is slidably set in the embedding groove. A fixed block 22 is fixedly installed on one side of the embedding groove close to the protection box 1, and there is a gap between the fixed block 22 and the second limiting plate 21. A pressure sensor 23 is installed on the side of the fixed block 22 close to the second limiting plate 21.

[0036] The protective net is arranged at the front end of the protective box 1, and the protective net has a protective effect on the electric energy meter body 24. The first limit plate 19 is located on the inner side of the protective net, and the protective net has a limiting effect on the first limit plate 19. Under the restriction of the protective net, the first limit plate 19 cannot move outward, and the box door 2 cannot be opened outward.

[0037] The protection net includes a plurality of protection rods movably arranged at the front end of the protection box 1. The protection box 1 is provided with a driving assembly for driving the protection rods to move.

[0038] The alarm 26 is arranged on the outer side wall of the protection box 1. When the criminals forcefully open the box door 2, the alarm 26 is activated, which deters the criminals and draws the attention of people around.

[0039] The protective box 1 is provided with a sensor 4, which is equipped with an identification card. The sensor 4, the pressure sensor 23, the alarm 26 and the drive assembly are all electrically connected to the controller. The remote monitoring center can also be connected to the controller signal. When the alarm 26 sounds an alarm, the signal is transmitted to the remote monitoring center at the same time, reminding the staff to rush to the site for inspection in time.

[0040] The identification card is placed close to the sensor 4 for identity verification. After the verification, the controller starts the driving component, which drives the protective rod to move, thereby releasing the limit of the first limit plate 19, and then the staff can open the door 2 outward. If the door 2 is opened outward by force, the first limit plate 19 cannot move outward under the limit of the protective net, and then the first limit plate 19 pulls the second limit plate 21 to move through the connecting rod 20, and the pressure sensor 23 is squeezed. The pressure sensor 23 transmits the pressure value to the controller. When the pressure value of the pressure sensor 23 reaches a certain level, the alarm 26 is activated to alarm.

[0041] In this embodiment, the plurality of protection bars are respectively a first transverse protection bar 10, a second transverse protection bar 11, a first vertical protection bar 17, and a second vertical protection bar 18. There are two first transverse protection bars 10, two second transverse protection bars 11, two first vertical protection bars 17, and two second vertical protection bars 18, wherein the two first transverse protection bars 10 are located between the two second transverse protection bars 11, and the first transverse protection bars 10 and the second transverse protection bars 11 are parallel to each other. The first transverse protection bar 10 and the second transverse protection bar 11 are arranged at the front end of the protection box 1 to move up and down. The two first vertical protection bars 17 are located between the two second vertical protection bars 18, and the first vertical protection bars 17 and the second vertical protection bars 18 are parallel to each other, and the first vertical protection bar 17 is located between the two second vertical protection bars 18 and is arranged at the front end of the protection box 1 to move left and right. The distance between the first transverse protection bar 10 and the adjacent second transverse protection bar 11 and the distance between the second transverse protection bar 11 and the corresponding inner wall of the protection box 1 are equal. The distance between the first vertical protection rod 17 and the adjacent second vertical protection rod 18 and the distance between the second vertical protection rod 18 and the corresponding inner wall of the protection box 1 are equal.

[0042] The driving assembly includes a first motor 6, a second motor 13, a first threaded rod 8, a second threaded rod 9, a third threaded rod 15 and a fourth threaded rod 16. Figure 6As shown, the first threaded rod 8 and the second threaded rod 9 are vertically rotatably installed in the protection box 1, and the first threaded rod 8 and the second threaded rod 9 are parallel. The first threaded rod 8 and the second threaded rod 9 both include an upper thread section and a lower thread section, and the upper thread section and the lower thread section have opposite spiral directions. The first threaded rod 8 and the second threaded rod 9 are of equal length, and the pitch of the thread on the second threaded rod 9 is twice the pitch of the thread on the first threaded rod 8. The left ends of the two first transverse protection rods 10 are both slidably connected to the first threaded rod 8, the right end of one of the first transverse protection rods 10 is threadedly connected to the upper thread section of the second threaded rod 9, and the right end of the other first transverse protection rod 10 is threadedly connected to the lower thread section of the second threaded rod 9. The right ends of the two second transverse protection rods 11 are both slidably connected to the second threaded rod 9, the left end of one of the second transverse protection rods 11 is threadedly connected to the upper thread section of the first threaded rod 8, and the left end of the other second transverse protection rod 11 is threadedly connected to the lower thread section of the first threaded rod 8.

[0043] The first threaded rod 8 and the second threaded rod 9 are connected by a first belt 7. The first motor 6 is fixedly mounted on the protection box 1, and the first motor 6 is connected to the first threaded rod 8. The first motor 6 drives the first threaded rod 8 to rotate, and under the action of the first belt 7, the first threaded rod 8 and the second threaded rod 9 rotate synchronously. Since the pitch of the second threaded rod 9 is twice that of the first threaded rod 8, the moving speed of the first transverse protection rod 10 is twice that of the second transverse protection rod 11.

[0044] The first motor 6 is electrically connected to the controller. The protection box 1 is provided with a first housing 5, and the first motor 6 is located in the first housing 5, which has a protective effect on the first motor 6.

[0045] The third threaded rod 15 and the fourth threaded rod 16 are both rotatably arranged in the protection box 1, and the third threaded rod 15 and the fourth threaded rod 16 are both perpendicular to the first threaded rod 8. The third threaded rod 15 and the fourth threaded rod 16 are of equal length and the pitch of the third threaded rod 15 is twice the pitch of the fourth threaded rod 16. The third threaded rod 15 and the fourth threaded rod 16 both include a left thread segment and a right thread segment, and the spiral directions of the left thread segment and the right thread segment are opposite. The upper end of one of the first vertical protection rods 17 is threadedly connected to the left thread segment of the third threaded rod 15, and the upper end of the other first vertical protection rod 17 is threadedly connected to the right thread segment of the third threaded rod 15. The lower ends of the two first vertical protection rods 17 are both slidably connected to the fourth threaded rod 16. The lower end of one of the second vertical protection rods 18 is threadedly connected to the left thread segment of the fourth threaded rod 16, and the lower end of the other second vertical protection rod 18 is threadedly connected to the right thread segment of the fourth threaded rod 16, and the upper ends of the two second vertical protection rods 18 are both slidably connected to the third threaded rod 15.

[0046] The third threaded rod 15 and the fourth threaded rod 16 are connected by a second belt 14. The second motor 13 is fixedly mounted on the protection box 1, and the motor shaft of the second motor 13 is coaxially fixedly connected with the third threaded rod 15. The second motor 13 drives the third threaded rod 15 to rotate, and under the action of the second belt 14, the third threaded rod 15 and the fourth threaded rod 16 rotate synchronously. Since the pitch of the third threaded rod 15 is twice the pitch of the fourth threaded rod 16, the moving speed of the first vertical protection rod 17 is twice the moving speed of the second vertical protection rod 18.

[0047] The second motor 13 is electrically connected to the controller, and a second housing 12 is fixed to the protective box 1. The second motor 13 is located in the second housing 12, and the second housing 12 protects the second motor 13. Both the first motor 6 and the second motor 13 have self-locking properties.

[0048] Working principle: Initially, the distance between the first transverse protection bar 10 and the adjacent second transverse protection bar 11 and the distance between the second transverse protection bar 11 and the corresponding inner wall of the protection box 1 are equal. The distance between the first vertical protection bar 17 and the adjacent second vertical protection bar 18 and the distance between the second vertical protection bar 18 and the corresponding inner wall of the protection box 1 are equal. The connecting rod 20 passes through the grid formed by the first transverse protection bar 10 and the first vertical protection bar 17. The first limit plate 19 is located on the side of the protection net close to the electric energy meter body 24.

[0049] When the staff performs maintenance on the electric energy meter body 24, the staff first inserts the key into the lock hole 3 to open the mechanical lock.

[0050] Afterwards, identity verification is performed by bringing the identification card close to the sensor 4. After verification, the first motor 6 and the second motor 13 are started. The first motor 6 drives the first threaded rod 8 to rotate, and the first threaded rod 8 drives the second threaded rod 9 to rotate synchronously through the first belt 7. The first threaded rod 8 drives the second transverse protection rod 11 to move outward, and the second threaded rod 9 drives the first transverse protection rod 10 to move outward. Since the pitch of the second threaded rod 9 is twice that of the first threaded rod 8, the moving speed of the first transverse protection rod 10 is twice that of the second transverse protection rod 11, and the distance between the first transverse protection rod 10 and the adjacent second transverse protection rod 11 gradually decreases. Until the second transverse protection rod 11 moves to the end of the first threaded rod 8, the first transverse protection rod 10 and the second transverse protection rod 11 are in contact.

[0051] At the same time, the second motor 13 drives the third threaded rod 15 to rotate, and the third threaded rod 15 drives the fourth threaded rod 16 to rotate synchronously through the second belt 14. The third threaded rod 15 drives the first vertical protection rod 17 to move outward, and the fourth threaded rod 16 drives the second vertical protection rod 18 to move outward, and the moving speed of the first vertical protection rod 17 is twice the moving speed of the second vertical protection rod 18, so the distance between the first vertical protection rod 17 and the adjacent second vertical protection rod 18 gradually decreases. Until the second vertical protection rod 18 moves to the end of the third threaded rod 15, the first vertical protection rod 17 contacts the corresponding second vertical protection rod 18. At this time, the protective net releases the protection of the first limit plate 19 and the electric energy meter body 24.

[0052] Then the staff can open the box door 2 outwards and perform maintenance on the electric energy meter body 24.

[0053] After the maintenance is completed, the staff first closes the box door 2, and then puts the identification card close to the sensor 4 again, and the first motor 6 and the second motor 13 rotate in the opposite direction. The first horizontal protection bar 10 and the second horizontal protection bar 11 as well as the second vertical protection bar 18 and the first limit plate 19 all move toward the middle direction until the protection net returns to the initial state, protecting the electric energy meter body 24 and limiting the first limit plate 19.

[0054] If criminals attempt to open the door 2 to steal electricity, they have no choice but to destroy the mechanical lock because they do not have a key. The mechanical lock provides the first layer of protection for the main body 24 of the electric energy meter.

[0055] If the mechanical lock is broken, since there is no identification card, criminals can only force the door 2 to open outward. If the door 2 is forced to open outward, due to the limiting effect of the protective net, the first limiting plate 19 is difficult to move outward, so that the second limiting plate 21 moves in the embedded groove toward the direction close to the fixed block 22, and then the pressure sensor 23 is squeezed, and the pressure sensor 23 transmits the pressure value to the controller. When the pressure value of the pressure sensor 23 reaches a certain value, the alarm 26 sounds an alarm. As the second limiting plate 21 moves toward the direction close to the fixed block 22, the second limiting plate 21 contacts the fixed block 22, and then the second limiting plate 21 is difficult to move, and the door 2 cannot be opened outward. The protective component provides a second layer of protection for the main body 24 of the electric energy meter.

[0056] If the protective assembly is damaged, so that the box door 2 is opened, the protective net protects the electric energy meter body 24, and it is difficult for criminals to access the electric energy meter body 24. Criminals can only steal electricity from the electric energy meter body 24 by destroying the protective net. The protective net provides the third layer of protection for the electric energy meter body 24.

[0057] By providing three layers of protection to the electric energy meter body 24, the criminals' crime-making time can be prolonged, so that people can discover and report the crime in time, and the probability of successful electricity theft by criminals can be effectively reduced.

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
