During the actual construction process, construction workers adjust the position of the brackets while installing electrical components, which seriously affects the construction efficiency. Therefore, an intelligent power grid power distribution cabinet is proposed to solve the above problems. Summary of the Invention

Detailed Implementation Modes

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0032] As Figure 1 、 Figure 2 、 Figure 3 and Figure 5 shown, a smart grid power distribution cabinet provided by an embodiment of the present invention includes a cabinet body 1, a cabinet door 2 is provided on one side of the cabinet body 1, and further includes:

[0033] An adjustable bracket located inside the cabinet body 1, the adjustable bracket includes guide rails 3 spaced on both sides inside the cabinet body 1, and the guide rails 3 are arranged vertically by themselves. A plurality of horizontal frames 4 in a horizontal state and used for installing electrical components are distributed between the two guide rails 3. Adaptive locking structures 5 are provided at both ends of the horizontal frame 4. The adaptive locking structure 5 is used to fix the position of the horizontal frame 4 between the two guide rails 3. A plurality of mounting holes 12 are arranged at intervals along the length direction of the horizontal frame 4. The mounting holes 12 are used to fix electrical components on the horizontal frame 4.

[0034] A driving assembly 6, the driving assembly 6 is used to adjust the position of the horizontal frame 4 in the power distribution cabinet;

[0035] As Figure 7 shown, when installing electrical components, the position information of the power distribution cabinet is obtained through the smart grid, and the horizontal frame 4 is controlled based on the position information. The specific steps include:

[0036] S100, retrieving line data in the smart grid according to the position information, and the line data is all circuits to be connected to the power distribution cabinet;

[0037] S200, analyzing to obtain component category information based on the line data by using electrical engineering software, and the component category information is the sum of all electrical components used in the power distribution cabinet;

[0038] S300, generating a layout plan by using electrical design software according to the component category information and the line data;

[0039] S400, generating an adjustment instruction according to the layout plan, and the adjustment instruction is used to control the driving assembly 6 so that the distance between the horizontal frames 4 in the power distribution cabinet changes and meets the space requirements of the electrical components.

[0040] In an embodiment of the present invention, the functions of the present invention are implemented based on the smart grid. After the installation position of the power distribution cabinet is determined, the circuits controlled by the power distribution cabinet can be learned through the management system of the smart grid. Then, it can be analyzed which electrical components are needed in the power distribution cabinet and specific models can be determined. After generating the layout through an automated electrical design software, the positions of each electrical component in the power distribution cabinet can be determined. At this time, the driving component 6 can be controlled to work, and the positions of each cross frame 4 can be adjusted through the driving component 6 so that the distance between the cross frames 4 can be automatically adjusted. When the construction workers install on-site, they can directly install the electrical components without manual adjustment. In summary, the present invention realizes the selection of electrical components inside the power distribution cabinet by using the smart grid and automatically adjusts the distribution of the installation structure, thereby significantly improving the installation efficiency of the power distribution cabinet.

[0041] It should be noted that there are various electrical components, such as circuit breakers, fuses, contactors, etc. The external dimensions of these electrical components are also different. If the distance between the cross frames 4 is relatively close, it is very likely that they cannot be installed. Therefore, it is necessary to flexibly adjust the distance between the cross frames 4. After obtaining the line data, detailed load calculations and demand analyses will be carried out through electrical engineering software (such as ETAP, SKM PowerTools or EPLAN). These tools can automatically calculate information such as the required power capacity and current load according to the requirements of the known circuit, and can also help select suitable electrical components. For example, they can recommend the specifications of suitable circuit breakers, contactors and other protection devices according to the calculated current load. In addition, these software also provide functions of power system simulation and emulation, allowing different configuration schemes to be tested in a virtual environment, evaluating the performance, stability and safety of the system, and ensuring that all components can work effectively together. Generating a layout plan according to the electrical design software is a conventional technical means and will not be described in detail. The so-called layout plan is the wiring plan of electrical components in the power distribution cabinet. When the position of each electrical component is determined, it will be analyzed whether the cross frame 4 in the initial state meets the installation requirements. If not, the driving component 6 can be controlled to adjust one or more cross frames 4.

[0042] Such as Figure 3 、 Figure 4As shown, as a preferred embodiment of the present invention, the driving assembly 6 includes a trough-shaped guide frame 601 fixedly connected inside the cabinet body 1 and arranged vertically. An installation block 602 capable of sliding is arranged inside the trough-shaped guide frame 601, and a lead screw 603 rotatably arranged inside the trough-shaped guide frame 601 and cooperatively connected with the installation block 602. A driving box body 604 for driving the lead screw 603 to rotate is arranged at the bottom of the cabinet body 1. A telescopic member 605 in a horizontal state is arranged on the installation block 602. The other end of the telescopic member 605 is fixedly connected with a U-shaped clamping block 606 facing the cross frame 4 and matching the shape of the cross frame 4. When the U-shaped clamping block 606 is cooperatively clamped with the cross frame 4, the adaptive locking structure 5 at both ends of the cross frame 4 is in an unlocked state, and at this time, the cross frame 4 can move inside the guide rail 3.

[0043] In one case of this embodiment, as Figure 5 and 6As shown in the figure, the adaptive locking structure 5 includes top blocks 501 located at both ends of the cross beam 4. The shape of the top blocks 501 matches the cross-section of the cross beam 4. The top blocks 501 and the cross beam 4 are fixedly connected by elastic telescopic rods 502. Limiting rods 7 capable of telescoping along the length direction of the cross beam 4 are arranged at both ends of the cross beam 4. The top blocks 501 are slidably sleeved on the limiting rods 7. A plurality of positioning holes 15 matching the limiting rods 7 are spaced apart on the guide rail 3. A top extension assembly for controlling the telescoping of the limiting rods 7 and cooperating with the U-shaped clamping block 606 is arranged inside the cross beam 4. An installation slot 8 is formed on one side of the cross beam 4 facing the U-shaped clamping block 606. Sliders 9 are slidably arranged on both sides inside the installation slot 8. The two sliders 9 on both sides are fixedly connected to the limiting rods 7, and an elastic member 10 located outside the limiting rods 7 is fixedly connected to the sliders 9. The other end of the elastic member 10 is fixedly connected to the inner wall of the installation slot 8. A connecting block 11 is arranged between the two sliders 9 inside the installation slot 8. The contact surface between the connecting block 11 and the slider 9 is a bevel structure, and the connecting block 11 and the slider 9 can only slide relative to each other and cannot be separated. When the elastic member 10 is in the initial state, one end of the limiting rod 7 is located inside the positioning hole 15, and the surface of the connecting block 11 facing the U-shaped clamping block 606 is located outside the installation slot 8. A motor or a motor can be arranged inside the driving box body 604 to control the rotation of the lead screw 603. The telescopic member 605 can be in the form of an electric telescopic rod. When it is necessary to move the cross beam 4, by controlling the rotation of the lead screw 603, the installation block 602 can be moved to a position flush with the cross beam 4. At this time, the telescopic member 605 controls the U-shaped clamping block 606 to be clamped with the cross beam 4. At this time, the U-shaped clamping block 606 will push the connecting block 11 to move into the installation slot 8. At this time, the two sliders 9 on both sides will drive the limiting rods 7 to retract. At this time, the cross beam 4 can move smoothly on the guide rail 3. When it moves to the designated position, at this time, the U-shaped clamping block 606 retracts, and the sliders 9 move to both sides under the pulling action of the elastic member 10. At this time, the connecting block 11 will also move outward synchronously, and the limiting rods 7 on both sides will also extend into the positioning holes 15 of the guide rail 3. The connection method between the top block 501 and the cross beam 4 is to be able to shorten the overall length of the cross beam 4, which is convenient for manual addition or reduction of the number of cross beams 4 between the two guide rails 3. The elastic member 10 can be in the form of a spring.

[0044] As Figure 3 shown, as a preferred embodiment of the present invention, a heat dissipation device 13 for exchanging the air inside the cabinet 1 with the outside is arranged on the top of the cabinet 1.

[0045] In a case of this embodiment, support feet 14 for lifting the height of the cabinet body 1 are fixedly connected to both sides of the bottom of the cabinet body 1. The heat dissipation device 13 adopts a conventional method in the prior art. The position adjustment of the cross frame 4 is not only used in the installation process of electrical components. After the power distribution cabinet is put into use, the working states of various devices of the power distribution cabinet can be monitored through the smart grid. When it is found that the working temperature of the electrical components on a certain cross frame 4 is abnormal, the distance between the adjacent cross frame 4 and this cross frame 4 can be adjusted, so that the space around the electrical components on this cross frame 4 increases, which can increase the efficiency of air flow and make its heat dissipate faster.

[0046] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
