A wire tying rack 122 is fixedly arranged on the front door 12 on the side of the reinforcing rib 121, which is convenient for the staff to sort out the wire harnesses of electronic components.
[0032] The top plate 15 is arranged at the top of the cabinet frame 11. Lifting lugs 151 are fixedly arranged at the four corners of the top of the top plate 15, and adjusting casters 152 are fixedly arranged at the four corners of the bottom of the base 2. The whole cabinet body 1 is moved through the lifting lugs 151, and the position of the cabinet body 1 can be finely adjusted through the adjusting casters 152, and at the same time, the position of the cabinet body 1 can be fixed.
[0033] The side plates 14 are respectively arranged on both sides of the cabinet frame 11. An installation beam 16 is detachably arranged on the inner side of the side plate 14, and electronic components can be installed on the installation beam 16. At least one storage rack 141 is horizontally arranged on the side plate 14 on the side of the installation beam 16. Drying items such as drying bags can be placed on the storage rack 141, so as to ensure the dryness inside the cabinet body 1 and avoid high humidity inside the cabinet body 1, which may cause short circuits or damage to electronic components. A replacement hole 142 is formed in the side plate 14 above the corresponding storage rack 141, and a baffle plate 143 for blocking the replacement hole 142 is detachably arranged on the side plate 14. When a failure occurs in the dimming cabinet and it is not convenient to repair from the front door 12, the baffle plate 143 on the side plate 14 can be removed, and the internal electronic components can be repaired through the replacement hole 142. At the same time, items such as drying bags can also be replaced through the replacement hole 142.
[0034] In order to realize the replacement of clean gas inside the dimming cabinet. Refer to Figures 2-5 , in this embodiment, a base 2 is detachably arranged at the bottom end of the cabinet body 1, and a dust-proof ventilation module 3 for replacing the gas inside the cabinet body 1 is arranged on the base 2. The dust-proof ventilation module 3 includes a support plate 31 fixedly arranged at the bottom end of the cabinet frame 11. A plurality of ventilation grooves 32 are formed in the support plate 31, and the connection between the inside of the cabinet body 1 and the base 2 is realized through the ventilation grooves 32. A ventilation chamber 33 that can be connected to the inside of the cabinet body 1 is formed inside the base 2. At least one ventilation fan 34 with a motor is fixedly arranged inside the ventilation chamber 33. The ventilation chamber 33 is connected to the inside of the cabinet body 1 through the ventilation fan 34. A heater 35 is also arranged inside the ventilation chamber 33, and the air is heated through the heater 35 to ensure a constant temperature inside the cabinet body 1 and avoid damage to electronic components caused by the cold external environment. An exhaust port 36 is fixedly arranged on the side of the heater 35, and an air exchange pipe 37 is arranged inside the ventilation chamber 33. A temperature sensor is also arranged inside the cabinet body 1.
[0035] The air exchange pipe 37 includes an air exchange main pipe 371 connected to the side of the heater 35. An air exchange branch pipe 372 inserted into the ventilation chamber 33 is vertically and fixedly arranged on the inner side of the side plate 14. Each air exchange branch pipe 372 is connected to the air exchange main pipe 371. At least one air inlet 38 is formed in the upper part of the air exchange branch pipe 372 relative to the position of the side plate 14, and the air inlet 38 penetrates through the side plate 14 to communicate with the outside. Since there is more dust in the air closer to the ground, if the air inlet 38 is arranged at the lower part of the cabinet body 1, more dust may be inhaled. A filter cloth 39 for blocking the air inlet 38 is detachably arranged on the outside of the side plate 14. The outside air enters the ventilation chamber 33 through the air inlet 38 and the air exchange pipe 37, and larger dust is filtered through the filter cloth 39.
[0036] A filter rack 40 for placing filter materials is fixedly arranged at the lower part of the position of the ventilation branch pipe 372 relative to the side plate 14 to finely filter the air entering the ventilation branch pipe 372 and prevent dust from entering the cabinet body 1 and damaging the electronic components. A material changing port 41 corresponding to the position of the filter rack 40 is formed in the ventilation branch pipe 372. The material changing port 41 penetrates through the side plate 14 and communicates with the outside. A material changing plate 42 for blocking the position of the material changing port 41 is detachably arranged on the side plate 14, and the filter material is replaced through the material changing port 41. The back plate 13 is detachably arranged at the rear end of the cabinet frame 11. An exhaust plate 43 is fixedly arranged on the back plate 13. The exhaust plate 43 is located at the upper part of the back plate 13 to prevent the dust on the ground from being blown up during exhaust, resulting in an increase in the filtering intensity. The filter cloth 39 is also arranged outside the back plate 13 to block the exhaust plate 43. The gas entering the cabinet body 1 is discharged from the exhaust plate 43, and the filter cloth 39 is used to prevent the outside dust from entering the cabinet body 1 through the exhaust plate 43.
[0037] The using method of the modular intelligent dimming cabinet based on the navigation light control of the utility model: First, the back plate 13, the side plates 14, the top plate 15 and the front door 12 are arranged on the cabinet frame 11. Then, the heater 35 and the ventilation main pipe 371 are connected, and the two are installed in the ventilation chamber 33 together with the ventilation fan 34. The cabinet body 1 is placed on the base 2 through the lifting lugs 151, and the ventilation branch pipe 372 is connected to the ventilation main pipe 371. The installation beam 16 is installed on the side plate 14, and the material changing plate 42, the shielding plate 143, the exhaust plate 43 and the filter cloth 39 are respectively installed on the side plate 14 and the back plate 13. The dimming cabinet is transported to a predetermined position through the lifting lugs 151, and the position is finely adjusted and fixed through the adjusting casters. Finally, the electronic components are installed on the installation beam 16. At this time, a drying bag can be placed on the storage rack 141 to ensure the dryness inside the dimming cabinet during operation.
[0038] When it is necessary to replace the gas inside the dimming cabinet and dissipate heat, according to the actual air volume requirement, the motor is controlled to work to make the corresponding ventilation fan 34 rotate. The ventilation fan 34 blows air from bottom to top. At this time, a suction force is generated in the ventilation chamber 33 to suck air from the air inlet 38, and the dust is filtered through the filter cloth 39 and the filter material on the filter rack 40, and the clean air is sucked into the ventilation main pipe 371. At this time, the operation of the heater 35 can be controlled according to the signal of the temperature sensor, so as to determine whether the air sucked into the heater 35 is heated. The air sucked into the heater 35 enters the ventilation chamber 33 from the exhaust port 36, and then enters the cabinet body 1 through the ventilation fan 34 and the ventilation groove 32, realizing ventilation or heating inside the cabinet body 1. The air entering the cabinet body 1 is discharged from the exhaust plate 43, forming an air circulation.
[0039] When the dimming cabinet fails and it is inconvenient to repair from the front door 12, the baffle 143 on the side plate 14 can be removed to perform maintenance operations on the internal electronic components through the replacement hole 142. At the same time, items such as drying bags can also be replaced through the replacement hole 142. When the filter material needs to be replaced, the material replacement plate 42 can be removed, and the filter material on the filter rack 40 can be replaced through the material replacement port 41.
