Description
Technical Field
[0001] This application relates to the technical field of distribution cabinets, and particularly relates to an anti-theft distribution cabinet. Background Art
[0002] Generally, power theft from distribution cabinets is caused by illegal connection. For example, wires are directly connected externally to the distribution box to illegally access electricity. Such power theft behavior not only affects the lives of residents, but also seriously damages the interests of the country and causes huge economic losses to power companies. In related technologies, some solutions for preventing power theft in distribution cabinets are merely to set a door opening password, and the lock on the cabinet door is just a single rod inserted into the cabinet shell for locking, which is easy to be pried open, the lock itself is not firm enough, and the anti-theft effect is weak. Utility Model Content
[0003] In order to solve the problem that the lock on the cabinet door is just a single rod inserted into the cabinet shell for locking, which is easy to be pried open and the lock itself is not firm enough, the following technical solutions are proposed in this application.
[0004] An anti-theft distribution cabinet includes a cabinet shell, a cabinet door, a motor, a gear, a rack, a limit box and a three-pronged rod. The cabinet door is hinged to the cabinet shell. The motor is installed on the inner surface of the cabinet door. The output shaft of the motor fixes the gear. The limit box is fixed to the inner surface of the cabinet door. The rack is adaptively installed in the strip-shaped limit box. The gear meshes with the rack. One end of the three-pronged rod is fixed to the rack, and the other end has three parallel cross bars. The cabinet shell has three jacks on the side opposite to the cabinet door. The motor can drive the rack to move linearly back and forth along the limit box, so that the three parallel cross bars are inserted into the three jacks one by one, or leave the three jacks and are completely received in the inner surface of the cabinet door.
[0005] By adopting the above technical solution, the three-pronged rod is used as the lock on the cabinet door, and the three parallel cross bars are inserted into the three jacks of the cabinet shell one by one to lock the cabinet door. This locking structure is relatively firm, not easily pried open, and has a good anti-theft effect. The limit box is preferably square bar-shaped.
[0006] A preferred solution of this anti-theft distribution cabinet is that the three-pronged rod further includes a main rod and a vertical rod. The rack is fixed to the main rod. The main rod is vertically connected to one side of the vertical rod, and the three parallel cross bars are vertically connected to the other side of the vertical rod.
[0007] By adopting the above technical solution, the structure of the three-pronged rod is simple and firm.
[0008] A preferred solution of the anti-theft power distribution cabinet is that the anti-theft power distribution cabinet further includes two limit blocks. The two limit blocks are fixed on the inner surface of the cabinet door, and the distances from the two limit blocks to the vertical rod are equal. When the three parallel cross bars are in a state of being fully inserted into the three jacks, the distance from the vertical rod to any one of the limit blocks is greater than the depth of the jack and less than the distance from the end of the rack connecting the main rod to the gear.
[0009] By adopting the above technical solution, the three-pronged rod can be driven to completely disengage from the cabinet shell, and the rotation of the motor is affected by the limit block and cannot disengage from the rack, always maintaining the effectiveness of meshing.
[0010] It should be noted that the distance from the end of the rack connecting the main rod to the gear is the co-directional meshing driving distance of the rack, that is, the distance from the connecting end of the rack and the main rod to the meshing center point.
[0011] A preferred solution of the anti-theft power distribution cabinet is that the axial ends of the limit box are open, and there is a relief opening in the middle. The rack is driven by the motor to move axially along the limit box. The gear passes through the relief opening but does not contact the limit box.
[0012] By adopting the above technical solution, the limit box can support the rack and limit the rack to only move axially; at the same time, the gear and the rack can be meshed and driven without interference from the limit box.
[0013] A preferred solution of the anti-theft power distribution cabinet is that the anti-theft power distribution cabinet includes an inverted L-shaped upper fixing plate and an L-shaped lower fixing plate. The upper fixing plate and the lower fixing plate are both fixed on the inner surface of the cabinet door. The motor is fixed between the upper fixing plate and the lower fixing plate. The gear is located between the motor and the cabinet door.
[0014] By adopting the above technical solution, the motor is fixed, and the motor and the gear can be on the same horizontal line; the gear is closer to the cabinet door, which is convenient for the three-pronged rod to be inserted into the jack of the cabinet shell in alignment.
[0015] A preferred solution of the anti-theft power distribution cabinet is that the anti-theft power distribution cabinet further includes an inclined rod, one end of the inclined rod is fixed on the lower surface of the lower fixing plate, and the other end is fixed on the inner surface of the cabinet door.
[0016] By adopting the above technical solution, the inclined rod strengthens the support for the lower fixing plate and the motor, making the motor more stable.
[0017] A preferred solution of the anti-theft power distribution cabinet is that the anti-theft power distribution cabinet further includes a control module, a face recognition module, an anti-stealing electricity module, an electric meter and a wireless communication module. The control module, the anti-stealing electricity module, the wireless communication module and the electric meter are all installed in the cabinet shell. The face recognition module is installed on the cabinet door and faces outside the cabinet door. The anti-stealing electricity module is connected to the electric meter, and the control module is respectively connected to the anti-stealing electricity module, the face recognition module, the wireless communication module and the motor.
[0018] By adopting the above technical solution, the anti-stealing electricity module judges whether there is electricity stealing behavior by monitoring the changes of data such as current, voltage and power of the electric meter, and transmits the data to the control module. The control module sends information to the cloud platform through the wireless communication module, and the background personnel can conduct further re-judgment and make corresponding treatment measures. The face recognition module can identify whether the face is the person allowed to open the cabinet door. If so, the control module controls the motor to start and open the cabinet door, otherwise the cabinet door is not opened.
[0019] A preferred solution of the anti-theft power distribution cabinet is that the lengths of the three parallel cross bars are equal, and the depths of the three jacks are equal.
[0020] By adopting the above technical solution, the three cross bars can be locked in real-time synchronization, the locking structure is firm, and the safety factor is higher.
[0021] In summary, the anti-theft power distribution cabinet of the present application has the following beneficial effects: The three-pronged bar is used as the lock on the cabinet door, and the three parallel cross bars are inserted into the three jacks of the cabinet shell one by one to lock the cabinet door. The locking structure is relatively firm and is not easily pried open, and the anti-theft effect is good. The limit box is preferably square bar-shaped. Description of the Drawings

Specific embodiments
[0030] The present application will be further described below with reference to the accompanying drawings.
[0031] Please refer to Figure 1 , an anti-theft power distribution cabinet, including a cabinet shell 1 and a cabinet door 2. Please refer to Figure 2 and Figure 3 , an anti-theft locking mechanism composed of a motor 3, a gear 4, a rack 5, a limit box 6 and a three-pronged rod 7 is further installed on the inner side surface of the cabinet door 2 of the anti-theft power distribution cabinet. The shape of the rack 5 can be further referred to Figure 4 , it is integrally square bar-shaped, with parallel continuous triangular pointed teeth on the upper surface, which can mesh with the gear 4, and the other three sides are smooth.
[0032] The cabinet door 2 is hinged to the cabinet shell 1.
[0033] The motor 3 is installed on the inner surface of the cabinet door 2. The output shaft of the motor 3 fixes the gear 4.
[0034] The limit box 6 is preferably square bar-shaped. The limit box 6 is fixed to the inner surface of the cabinet door 2. The rack 5 is adaptively installed in the strip-shaped limit box 6.
[0035] The gear 4 meshes with the upper surface tooth surface of the rack 5.
[0036] Please refer to Figure 5 , one end of the three-pronged rod 7 is fixed to the rack 5, and the other end has three parallel cross bars 701, and the three cross bars 701 are arranged equidistantly from top to bottom. The lengths of the three parallel cross bars 701 are preferably equal.
[0037] Please refer to Figure 6, on one side of the cabinet shell 1 opposite to the cabinet door 2, there are three jacks 101, and the depths of the three jacks 101 are preferably equal. Preferably, the length of the cross bar 701 is greater than the depth of the jack 101. The motor 3 can drive the rack 5 to move linearly back and forth along the limit box 6, so that the three parallel cross bars 701 are inserted into the three jacks 101 one by one, or leave the three jacks 101 and are completely received in the inner surface of the cabinet door 2. These three cross bars 701 can lock the cabinet shell 1 in real time synchronously, with a firm locking structure and a high safety factor.
[0038] The above-mentioned three-pronged bar 7 serves as a movable lock bar on the cabinet door 2. By inserting the three parallel cross bars 701 of it into the three jacks 101 of the cabinet shell 1 one by one to lock the cabinet door 2. Compared with the locking method of a single bar, the locking structure of this method is relatively firm and is relatively not easy to be pried open.
[0039] Please refer to Figure 5 , an optional structure of the three-pronged bar 7 is that the three-pronged bar 7 further includes a main bar 702 and a vertical bar 703. The rack 5 is fixed to the main bar 702. The main bar 702 is vertically connected to one side of the vertical bar 703, and the three parallel cross bars 701 are vertically connected to the other side of the vertical bar 703. The cross bar 701 can be cylindrical, and the jack 101 is a matching cylindrical hole. The structure of the three-pronged bar 7 is simple and firm.
[0040] Please refer to Figure 3 , in order to prevent the meshing drive from disengaging, it is designed that the anti-theft power distribution cabinet further includes two limit blocks 8. The two limit blocks 8 are fixed to the inner surface of the cabinet door 2, and the distances from the two limit blocks 8 to the vertical bar 703 are kept equal. When the three parallel cross bars 701 are in the state of being completely inserted into the three jacks 101, the distance from the vertical bar 703 to any one of the limit blocks 8 is greater than the depth of the jack 101 and less than the distance from the end of the rack 5 connected to the main bar 702 to the gear 4. Then the three-pronged bar 7 can be driven to completely disengage from the cabinet shell 1 to open the door, and the rotation of the motor 3 is affected by the limit block 8 and cannot disengage from the rack 5, and the meshing connection between the gear 4 and the rack 5 is always maintained.
[0041] It should be noted that the distance from the end of the rack 5 connected to the main bar 702 to the gear 4 is the co-directional meshing drive distance of the rack 5, that is, the distance from the connection end of the rack 5 and the main bar 702 to the meshing center point.
[0042] Please refer to Figure 7, in order to achieve the stable linear movement of the rack 5, the axial ends of the limit box 6 are provided with openings, and there is a relief opening 601 in the middle. The rack 5 is driven by the motor 3 to move axially along the limit box 6. The gear 4 passes through the relief opening 601 but does not contact the limit box 6. The limit box 6 with this structure can support the rack 5 and limit the rack 5 to only perform axial movement. At the same time, the gear 4 and the rack 5 can mesh and transmit power without being interfered by the limit box 6.
[0043] Please refer to Figure 3 , in order to firmly fix the motor 3 and keep the motor 3 in stable axial rotation output during operation, it is designed that the anti-theft power distribution cabinet includes an inverted L-shaped upper fixing plate 9 and an L-shaped lower fixing plate 10. The upper fixing plate 9 and the lower fixing plate 10 are both fixed on the inner surface of the cabinet door 2. The motor 3 is fixed between the upper fixing plate 9 and the lower fixing plate 10. The gear 4 is located between the motor 3 and the cabinet door 2. The motor 3 is firmly fixed, and the motor 3 and the gear 4 can be on the same horizontal line. At the same time, the gear 4 is closer to the cabinet door 2. Since the cabinet door 2 and the cabinet shell 1 are generally flush and aligned, this design facilitates the meshing three-pronged rod 7 to be inserted into the jack 101 of the cabinet shell 1.
[0044] Please refer to Figure 3 , in order to strengthen the stability of the motor 3, it is designed that the anti-theft power distribution cabinet further includes an inclined rod 11. One end of the inclined rod 11 is fixed on the lower surface of the lower fixing plate 10, and the other end is fixed on the inner surface of the cabinet door 2. The inclined rod 11 strengthens the support for the lower fixing plate 10 and the motor 3, making the operation of the motor 3 more stable.
[0045] Please refer to Figure 6 and Figure 1 , in order to strengthen the anti-theft and anti-electricity protection of the power distribution cabinet, it is designed that the anti-theft power distribution cabinet further includes a control module 12, a face recognition module 13, an anti-stealing electricity module 14, an electric meter 15 and a wireless communication module 16. The control module 12, the anti-stealing electricity module 14, the wireless communication module 16 and the electric meter 15 are all installed in the cabinet shell 1.

[0046] In this power distribution cabinet, the control module 12 can be a single-chip microcomputer or the like.
[0047] The anti-stealing electricity module 14 can use the sectional line loss anti-stealing electricity detector sold by Ruifannuo (Hebei) Electric Power Technology Co., Ltd., with the model number NRY81, which supports substation grading and phase-by-phase line loss monitoring, supports branch line detection; supports substation topology relationship identification; supports large user or key user monitoring. By monitoring the line load of the substation, including collecting data such as voltage, current, and electric energy, it judges whether there is electricity stealing behavior, realizes the grading and phase-by-phase line loss analysis and early warning function from the transformer - branch box - meter box, and prevents the occurrence of electricity stealing behavior. If it is judged that there is electricity stealing behavior, the single-chip microcomputer sends information to the cloud platform through the wireless communication module 16, and the cloud platform notifies the staff for further analysis and processing.
[0048] The face recognition module 13 can use the TM-AL02 dynamic face recognition attendance access control all-in-one machine provided by Shenzhen Youlian Tianmei Technology Co., Ltd., which has face recognition function and illegal door opening alarm function.
[0049] The wireless communication module 16 can be a GPRS communication module, etc.
[0050] The anti-stealing electricity module 14 judges whether there is electricity stealing behavior by monitoring the changes in data such as current, voltage, and power of the electric meter 15, and transmits the data to the control module 12. The control module 12 sends information to the cloud platform through the wireless communication module 16, and the background personnel can conduct further rejudgment and make corresponding treatment measures. The face recognition module 13 can identify whether the face is the person allowed to open the cabinet door 2. If so, the control module 12 controls the start of the motor 3 to open the cabinet door 2, otherwise the cabinet door 2 is not opened to prevent electricity stealing behavior.
[0051] The above are only the preferred embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various equivalent replacements and modifications can be made according to the above description, and these replacements and modifications should be covered within the protection scope of the present application.
