Specific implementation

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application;Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments;Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Reference Figures 1-5 A safety warning electric control cabinet is provided with a cabinet 1, the top of the cabinet 1 is provided with a heat dissipation cylinder 3 for heat dissipation and ventilation, a plurality of ventilation grooves are formed in the inside of the heat dissipation cylinder 3, and a dehumidification assembly is arranged at the bottom of the heat dissipation cylinder 3.

[0029] The dehumidification assembly comprises a dehumidification runner 8, the inside of the dehumidification runner 8 is fixedly connected with a rotating rod 17, the inside of the cabinet 1 is fixedly connected with a fixed plate 13, the top of the fixed plate 13 is fixedly connected with a cylinder 14, the cylinder 14 is rotationally connected with the rotating rod 17, both ends of the cylinder 14 are fixedly connected with connecting rods 9, the upper and lower ends of the dehumidification runner 8 are respectively provided with an air inlet cylinder 20 and an air outlet cylinder 10, and the dehumidification assembly further comprises a motor 16.

[0030] When the motor 16 is started, the output end drives the rotating rod 17 to rotate, so that the dehumidification runner 8 rotates. When the humid air enters the dehumidification runner 8 through the ventilation slot of the heat dissipation cylinder 3, the dehumidification runner 8 adsorbs the moisture in the air. With the continuous rotation of the dehumidification runner 8, the humidity of the air entering the cabinet 1 can be effectively reduced, the dry environment inside the cabinet 1 can be maintained, and the electrical components can be protected. In this process, the cylindrical column 14 supports and stabilizes the rotation of the dehumidification runner 8 through the connecting rod 9, so that the dehumidification runner 8 can run smoothly.

[0031] The dehumidification runner 8 is made of a hygroscopic material, which can be a composite material of silica gel and molecular sieve in the prior art.

[0032] Referring to Figures 2-5 The top of the cabinet 1 is provided with a protective shell 4, the inside of the protective shell 4 is provided with a fan 12, one end of the fan 12 is provided with a heater 18, the fan 12 and the heater 18 are connected in communication through a pipe, and the top end of the heater 18 is connected in communication with an air inlet pipe 19. One end of the air inlet pipe 19 extends through the inside of the heat dissipation cylinder 3 and is connected in communication with the air inlet cylinder 20. One end of the air outlet cylinder 10 is connected in communication with the air outlet pipe 11, and the air outlet pipe 11 extends through to the outside of the cabinet 1.

[0033] When the dehumidification runner 8 rotates between the two connecting rods 9, the fan 12 is started at this time to suck in the external air. The air is first heated by the heater 18, then enters the air inlet cylinder 20 through the air inlet pipe 19, and reaches between the two connecting rods 9 of the dehumidification runner 8, so that the moisture adsorbed in the dehumidification runner 8 evaporates into water vapor and is discharged from the air outlet pipe 11, so that the dehumidification runner 8 can restore the moisture absorption capacity.

[0034] Compared with the drying bag in the prior art, the dehumidification runner 8 can continuously rotate to absorb moisture and regenerate. When the dehumidification runner 8 rotates between the two connecting rods 9, the heated air makes the moisture adsorbed therein evaporate rapidly, ensuring that the runner can quickly restore strong moisture absorption capacity and always maintain high-efficiency dehumidification state, ensuring long-term effective control of the humidity in the electrical control cabinet and avoiding damage caused by continuous humidity rise.

[0035] Referring to Figures 3-4 One end of the cabinet 1 is provided with a capacitive humidity sensor 15, the top of the cabinet 1 is provided with an audible and visual alarm 6, the inside of the cabinet 1 is provided with a controller, and the controller is electrically connected with the audible and visual alarm 6, the capacitive humidity sensor 15, the motor 16 and the heater 18.

[0036] The capacitive humidity sensor 15 at one end of the cabinet 1 monitors the internal humidity in real time and transmits the humidity data to the controller inside the cabinet 1. Initially, the dehumidification runner 8 is already working, and if the humidity changes subsequently, the dehumidification runner 8 maintains the current working state when the humidity does not exceed the preset higher threshold value. When the humidity exceeds the higher threshold value but does not reach the serious over-standard threshold value, the dehumidification runner 8 increases the rotation speed to enhance the dehumidification capacity. When the humidity seriously exceeds the standard, the dehumidification runner 8 runs at full speed, and the heater 18 increases the heating temperature. If the humidity continues to seriously exceed the standard or the humidity does not decrease to the safe range after the dehumidification runner 8 works for a period of time, the controller triggers the audible and visual alarm 6 at the top of the cabinet 1 to issue an alarm.

[0037] The capacitive humidity sensor 15 can accurately detect the humidity, and the controller can accurately control the dehumidification runner 8 and the heater 18 accordingly, so as to ensure that the humidity in the cabinet 1 is always within the appropriate range. The audible and visual alarm 6 can timely remind the staff when the humidity is abnormal and the dehumidification effect is poor, so that maintenance measures can be taken quickly, and the risk of equipment failure can be reduced.

[0038] With reference to Figures 1-2 , the front end of the cabinet 1 is provided with a sealing door 2, one end of the sealing door 2 is provided with a handle, and the bottom of the cabinet 1 is provided with two support plates 7.

[0039] Working principle: first, when the cabinet 1 is normally running, the dehumidification runner 8 is already in working state. The output end of the motor 16 drives the rotating rod 17 to rotate, so that the dehumidification runner 8 rotates. When the humid air enters the dehumidification runner 8 through the ventilation slot of the heat dissipation cylinder 3, the dehumidification runner 8 will adsorb the moisture in the air, thereby reducing the humidity of the air entering the cabinet 1, and protecting the electrical elements.

[0040] In the running process of the dehumidification runner 8, when the runner rotates to the position between the two connecting rods 9, the fan 12 starts to suck the external air. The air is first heated by the heater 18, and then enters the air inlet cylinder 20 through the air inlet pipeline 19 to reach the area of the dehumidification runner 8. The hot air evaporates the water adsorbed in the dehumidification runner 8 into water vapor, and then is discharged from the air outlet pipeline 11, so that the dehumidification runner 8 can restore strong moisture absorption capacity, thereby being able to continuously and efficiently perform the dehumidification work.

[0041] At the same time, the capacitive humidity sensor 15 at one end of the cabinet 1 monitors the humidity inside the cabinet 1 in real time and transmits the data to the controller inside the cabinet 1. If the humidity does not exceed the preset higher threshold value, the dehumidification runner 8 maintains the current working state. Once the humidity exceeds the higher threshold value but does not reach the serious over-standard threshold value, the dehumidification runner 8 will increase the rotation speed to enhance the dehumidification capacity. When the humidity seriously exceeds the standard, the dehumidification runner 8 runs at full speed, and the heater 18 increases the heating temperature to enhance the dehumidification effect.

[0042] If the humidity continues to exceed the standard seriously, or the humidity does not decrease to the safe range after the dehumidification wheel 8 works for a period of time, the controller triggers the sound-light alarm 6 at the top of the cabinet 1 to issue an alarm. In this way, the staff can know the abnormal humidity in time and take maintenance measures quickly to reduce the risk of equipment failure.

[0043] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
