DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] This embodiment can monitor the internal humidity and dripping of the rectifier cabinet by setting up a humidity sensor and a dripping sensor component, and can send out an audible and visual alarm through the audible and visual alarm component when the humidity is too high or dripping occurs in an abnormal state, so as to remind the staff to deal with it in time, thereby avoiding water infiltration into the rectifier cabinet and affecting the safe use of the rectifier cabinet. At the same time, it also provides a multiple automatic water seepage alarm structure for the rectifier cabinet, and makes the water seepage warning function of the rectifier cabinet more sufficient and stable. The specific implementation method is as follows:

[0032] like Figures 1 to 4As shown, a new rectifier cabinet with a water seepage alarm structure includes a cabinet 1, a humidity sensor 9, a dripping sensing component and a sound and light alarm component. A rectifier control element 8 is arranged inside the cabinet 1, and a humidity sensor 9 and a dripping sensing component are installed between the rectifier control element 8 and the cabinet 1. The humidity sensor 9 is installed in the middle of the inner wall of the cabinet 1, and a dripping sensing component is arranged at the bottom of the cabinet 1. The dripping sensing component includes a support plate 11, a water drop detection plate 12 and a dripping sensor 13. The water drop detection plate 12 is installed on the support plate 11, and a dripping sensor 13 is installed at the bottom of the support plate 11. The detection end of the dripping sensor 13 is connected to the water drop detection plate 12, and the water drop detection plate 12 is arranged directly below the rectifier control element 8. A cabinet door 2 is hinged on the front of the cabinet 1, and a sound and light alarm component is arranged on the cabinet door 2. The sound and light alarm component includes an abnormal indicator light 3 and a buzzer 18. The humidity sensor 9 and the dripping sensing component are provided to monitor the internal humidity and dripping of the rectifier cabinet. When the humidity is too high or dripping occurs in an abnormal state, an audible and visual alarm can be issued through the audible and visual alarm component to remind the staff to deal with it in time, thereby avoiding water seepage into the rectifier cabinet and affecting the safe use of the rectifier cabinet. At the same time, it also provides a multiple automatic water seepage alarm structure for the rectifier cabinet, and makes the water seepage warning function of the rectifier cabinet more complete and stable.

[0033] The abnormal indicator light 3 is installed on the top of the outer surface of the cabinet door 2, the buzzer 18 is installed on the back of the cabinet door 2, and a speaker opening 5 is formed on the front of the cabinet door 2 at a position corresponding to the buzzer 18, and a dustproof net 6 is arranged on the inner side of the speaker opening 5. The sound of the buzzer 18 can be easily diffused outward through the speaker opening 5, and dust can be prevented from entering the interior of the speaker opening 5 through the dustproof net 6.

[0034] The humidity sensor 9 and the drip sensor 13 are electrically connected to the abnormal indicator light 3 and the buzzer 18 through the controller. Through the abnormal indicator light 3, when the humidity sensor 9 detects that the humidity is too high or the drip sensor 13 detects that there is a water leak or dripping phenomenon inside the cabinet 1, a flashing light can be emitted. Through the buzzer 18, when the humidity sensor 9 detects that the humidity is too high or the drip sensor 13 detects that there is a water leak or dripping phenomenon inside the cabinet 1, an alarm can be sounded. Under the joint action of the two, an audible and visual alarm can be realized, which is convenient for more intuitively reminding the staff. The controller is a PLC controller, which is arranged on the rectifier control element 8.

[0035] The support plate 11 is installed at the bottom of the inner side of the cabinet 1 through two support blocks 10. The water drop detection plate 12 is connected to the detection end of the drip sensor 13 through two copper wires 14 passing through the support plate 11. The water drop detection plate 12 includes an insulating plate and a resistance wire thereon, and the resistance wire is connected to the copper wire. When water drops from leakage fall on the water drop detection plate 12, it will cause the resistance value of the water drop detection plate 12 to change, thereby causing the voltage and current at both ends of the water drop detection plate 12 to change rapidly, and can be captured by the drip sensor 13 through the copper wire 14, so that the dripping situation inside the cabinet 1 can be quickly identified. The drip sensor 13 is a common voltage sensing switch in the prior art, which can monitor the voltage change of the water drop detection plate 12.

[0036] The cabinet 1 is provided with a drying assembly, which includes a drying box 4 and a drying fan 15. The drying box 4 is provided on the side wall of the cabinet 1, and the drying fan 15 is provided inside the drying box 4. The output end of the drying fan 15 is connected to the inner wall of the cabinet 1 through a drying pipe 16. The drying assembly provided on the side wall of the rectifier cabinet can be started when the humidity sensor 9 detects that the humidity inside the rectifier cabinet is too high, and the inside of the rectifier cabinet is dehumidified through the drying fan 15, so as to avoid the control components inside the rectifier cabinet being damaged by moisture due to low humidity, and further improve the service life of the rectifier cabinet.

[0037] The input end of the drying fan 15 is connected to an air inlet 17 , which is arranged in the middle of the outer surface of the drying box 4 . A dust blocking net is arranged on the air inlet 17 , and air can be easily taken into the drying fan 15 through the air inlet 17 .

[0038] The inner wall of the cabinet body 1 is installed with a reinforcing plate 20, and the inner wall of the reinforcing plate 20 is installed with an anti-seepage plate 21. By arranging the reinforcing plate 20 outside the rectifier cabinet, the strength of the rectifier cabinet body 1 can be improved and the impact of collision on it can be reduced. By arranging the anti-seepage plate 21 on the inner wall of the cabinet body 1, the waterproof and anti-seepage ability of the rectifier cabinet can be improved. The material of the anti-seepage plate 21 is a melamine board.

[0039] The outer wall of the cabinet 1 is provided with an insulating layer 19 , and the material of the insulating layer 19 is epoxy resin insulating material. The insulating layer 19 can improve the insulation performance of the exterior of the cabinet 1 .

[0040] A humidity display 7 is installed in the middle of the front of the cabinet door 2. The humidity display 7 is electrically connected to the humidity sensor 9. Through the humidity sensor 9, the humidity conditions inside the rectifier cabinet can be displayed, which is convenient for the staff to check. The humidity sensor 9 is connected to the humidity display 7 and the drying fan 15 through the PLC controller to facilitate automatic control thereof.

[0041] A sealing rubber ring is provided at the connection between the cabinet door 2 and the cabinet body 1. By providing the sealing rubber ring, the sealing performance of the connection between the cabinet door 2 and the cabinet body 1 can be improved, dust and water vapor can be prevented from entering the rectifier cabinet, and the anti-seepage effect of the rectifier cabinet is further improved.

[0042] Working principle: Humidity sensors and dripping sensors are set inside the rectifier cabinet to monitor the internal humidity and dripping of the rectifier cabinet. In abnormal conditions, when the humidity is too high or dripping occurs, the sound and light alarm component can send out an audible and visual alarm to remind the staff to deal with it in time, avoiding water infiltration into the rectifier cabinet and affecting the safe use of the rectifier cabinet. At the same time, it also provides multiple automatic water seepage alarm structures for the rectifier cabinet, making the water seepage warning function of the rectifier cabinet more complete and stable. The sound and light alarm component consists of an abnormal indicator light and a buzzer. In the event of water seepage, the abnormal indicator light will flash and the buzzer will sound an alarm. The drying component installed on the side wall of the rectifier cabinet can be started when the humidity sensor detects that the humidity inside the rectifier cabinet is too high, and the drying fan can be used to dehumidify the inside of the rectifier cabinet to prevent the internal control components of the rectifier cabinet from being damaged by moisture due to low humidity, further improving the service life of the rectifier cabinet. By installing a reinforcement plate on the outside of the rectifier cabinet, the strength of the rectifier cabinet can be improved and the impact of collision on it can be reduced. By installing an anti-seepage plate on the inner wall of the cabinet, the waterproof and anti-seepage ability of the rectifier cabinet can be improved.
