DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the utility model is further described in detail in the following with the help of drawings and examples.It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected;For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to specific circumstances.

[0027] I、The working principle of the utility model:

[0028] The electric box body 1 is a frame structure for mounting electrical components. It includes a box body 101 and a cover body 102 which is detachably arranged on the side of the box body 1, facilitating operation and maintenance of the inside of the box. One side of the box body 101 is provided with a plurality of air inlets 103, and the corresponding side is provided with cooling fans 104, so that the heat dissipation of the inside of the box is realized by air convection, ensuring that the electrical components work in a suitable temperature environment, avoiding damage or performance degradation due to overheating. The upper two sides of the box body 1 are provided with handles 105 for easy moving of the electric box, and the bottom two sides are provided with supporting feet 106 to keep the electric box stable and at a certain distance from the placement plane, which is beneficial to air circulation, etc. In addition, the outer side of the box body 101 is also provided with a main switch 107 and a power indicator light 108. The main switch is used to control the power-on condition of the entire electric box, and the power indicator light directly displays the power-on state of the electric box, making it easy for users to quickly know.

[0029] The independent unit module 2 specifically includes a pull-out frame 201 for mounting electronic components contained in the independent channel. For example, a channel with one 1P circuit breaker can be designed as an independent unit module, which can be checked, repaired and replaced in a separate plug-in manner. It has two design ways of standing multiple side-by-side and laying side-by-side, and mainly has 6-way-96-way channels. There are two forms of open appearance and hidden type plus an additional movable door to cover the entire row of modules. The design of such independent unit module makes it unnecessary to disassemble the entire machine when a component fails, and the corresponding module can be directly pulled out for processing, greatly improving the convenience of maintenance and saving costs.

[0030] The terminal 3 corresponds to the independent unit module 2 and is arranged on the side of the box body 101. Its function is to realize the connection between the independent unit module and the external line, and to ensure the transmission of electrical signals and electric energy.

[0031] The main controller 4 is fixedly arranged in the box body 101 and is used to connect the independent unit module 2 and the terminal 3. It plays a role in controlling each independent unit module and coordinating the electrical signal transmission between modules, and realizes the intelligent control of the entire electric cabinet electric box.

[0032] The pull frame 201 is provided with an independent switch 202 at one end, through which the power supply of the corresponding independent unit module can be controlled independently, facilitating safe power-off during maintenance and the like. The other end is provided with a winding coil 203, which is a spring structure and is made of insulating rubber material. When the independent unit is pulled out, the winding coil is not disconnected from the main controller, ensuring that the circuit remains connected when the module is pulled out for inspection, maintenance and the like, without affecting the normal circuit state of the equipment, facilitating rapid inspection and maintenance. At the same time, one side of the pull frame 201 is provided with an opening for facilitating operation and observation of the internal elements, and the other three sides are provided with a plurality of heat dissipation holes to further enhance the heat dissipation performance of the independent unit module, which cooperates with the overall heat dissipation design of the box body to ensure good heat dissipation of the internal electrical elements.

[0033] The vertical plate 5 is provided between the pull frame 201 and the main controller 4, and the winding coil 203 is fixedly connected to the vertical plate 5, and the vertical plate 5 is provided with a through hole 501. After the power cord of the pull unit 2 passes through the winding coil 203, it is connected to the main controller 4 along the through hole 5. Such a design makes the layout of the circuit more reasonable and orderly, facilitating installation and subsequent line troubleshooting and maintenance, and also ensuring the stability of the circuit during pulling.

[0034] When the electrical box is powered on, the power supply is connected through the main switch 107, and the power supply indicator 108 is lit to indicate that the power supply is normal. Each independent unit module 2 is connected to the external circuit through the terminal 3 and works under the control and coordination of the main controller 4. For example, in a stage lighting application scenario, different independent unit modules can control different areas or different functional lighting equipment. When an electrical element such as a 1P circuit breaker or a relay in a certain independent unit module fails and needs to be repaired, the power supply of the corresponding module can be cut off through the independent switch 202 on the pull frame 201, and then the independent unit module is pulled out. Due to the presence of the winding coil 203, the power cord will not be disconnected from the main controller 4, and the maintenance personnel can conveniently check, repair or replace the elements in the module. After the repair is completed, the module is pushed back to the original position, and the independent switch is turned on again to restore normal work. During the entire process, the air inlet 103, the cooling fan 104 and the heat dissipation holes of the independent unit module continue to work, ensuring that the internal electrical elements operate in a suitable temperature environment and avoiding overheating failure.

[0035] II. DETAILED EMBODIMENT

[0036] First, the electrical box body 1 is assembled, and the frame components of the box body 101 are spliced and fixed according to the design requirements to ensure that the structure is firm. Then, the air inlet 103, the cooling fan 104, the handle 105, the support foot 106, the main switch 107 and the power supply indicator 108 are installed at the corresponding positions of the box body 101 to ensure firm installation and normal operation of each component.

[0037] Then the independent unit module 2 is assembled, the pull frame 201 is built, the independent switch 202 is installed at one end of the pull frame 201, the winding coil 203 is installed at the other end, and the opening is opened and the heat dissipation hole is arranged on the appropriate side of the pull frame 201. Then the required electronic components such as 1P circuit breaker, relay and the like are installed into the pull frame 201, and the preliminary line connection is carried out according to the designed line connection mode, so as to ensure that each element is connected correctly and stably.

[0038] Then the vertical plate 5 is installed into the corresponding position in the box body 101, and the winding coil 203 is fixedly connected to the vertical plate 5, and at the same time the position of the through hole 501 on the vertical plate 5 is ensured to be accurate, so as to facilitate the subsequent passing and connection of the power line.

[0039] Then the main controller 4 is fixedly installed in the specified position in the box body 101, and then the power line of each independent unit module 2 is wound through the winding coil 203 and connected to the main controller 4 through the through hole 501 of the vertical plate 5, so as to ensure the normal communication and power supply line.

[0040] Finally, the cover 102 is installed on the side of the box body 101, and the cover is ensured to be detachable and firmly installed by a suitable connection mode such as screw fixing, and thus the whole 19U standard cabinet drawer type intelligent electric cabinet electric box is assembled.

[0041] When used for the first time, the electric box is placed in a suitable position such as a stage light control area of a machine room by the supporting leg 106, connected to the wire connector 3 outside the box body 101 by an external power line, and then the total switch 107 is opened. Whether the power indicator 108 is bright or not is observed, if it is bright, it indicates that the power is normal, and the whole electric cabinet enters the standby state.

[0042] According to the actual stage light control requirement, the main controller 4 is configured and programmed to each independent unit module 2, and the corresponding light control area, light brightness, switch time and other parameters of each independent unit module are set, so that each module can control the stage light according to the preset requirement.

[0043] In the daily operation process, the running state of the electrical cabinet is monitored in real time by observing the power indicator light 108 and the state indicator light that may be equipped on each independent unit module 2, etc. If it is found that the light of a certain area is abnormal, the corresponding independent unit module can be quickly judged, and then the independent switch 202 on the pull frame 201 of the module is operated to power off, and then the independent unit module is pulled out. During the pulling-out process, the power line still maintains the connection with the main controller 4 due to the action of the winding coil 203, and the maintenance personnel can check the electrical elements in the module, such as whether the 1P circuit breaker trips, whether the relay works normally, etc. If a faulty element is found, corresponding maintenance or replacement is performed, and then the independent unit module is pushed back to the original position, the independent switch 202 is opened again, and the module resumes normal work, and the entire stage lighting system can continue to operate normally.

[0044] After a long time of use, the electrical cabinet can be regularly checked and maintained, such as cleaning the dust and other sundries at the air inlet 103, the cooling fan 104 and the heat dissipation holes of the independent unit module, etc. to ensure that the heat dissipation system works normally, and to check whether the line connection is loose, whether the electrical elements have signs of aging, etc. and to timely perform corresponding treatment to ensure the long-term stable operation of the electrical cabinet.

[0045] In addition to the above-mentioned cleaning of the heat dissipation components and checking of the line and element state, regular maintenance also needs to perform functional test on each independent unit module 2. The main controller 4 can send corresponding test instructions to check the response of each module to ensure that its control function is normal.

[0046] For the electrical elements in the independent unit module 2, a reasonable replacement plan is made according to the service life and use frequency, etc. For example, for the 1P circuit breaker, relay and other elements that frequently act, even if there is no failure after reaching a certain number of uses or service life, preventive replacement is also performed to avoid sudden failure affecting the stage lighting effect in actual use.

[0047] If the cooling fan 104 fails, the cooling fan 104 can be repaired or replaced by disassembling the corresponding protective components on the side of the cabinet 101. After the operation is completed, the protective components are reinstalled to ensure that the heat dissipation system operates normally. Similarly, if other components such as the main switch 107, the power indicator light 108, etc. have problems, they can also be processed according to the corresponding disassembly and replacement process to ensure that all components of the electrical cabinet are in good working condition.

[0048] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
