Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an inlet and outlet line sealing mechanism for a power distribution cabinet. Background Art

[0002] The power distribution cabinet is a key equipment in the power system, which is used to centrally manage, distribute and protect power equipment.

Among them, the inlet and outlet sealing mechanism is an important part of the power distribution cabinet. Its function is to prevent dust and moisture, effectively isolate the external environment, improve the safety of electrical equipment, and prevent the spread of fire. At the same time, it also takes into account the convenience of maintenance, making the inspection and maintenance of electrical equipment more convenient. In general, the use of inlet and outlet sealing mechanisms not only helps to ensure the safe and reliable operation of the equipment inside the power distribution cabinet, but also improves the performance and safety of the entire electrical system.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-2, the utility model provides an embodiment: a sealing mechanism for inlet and outlet lines of a power distribution cabinet, comprising a cabinet body 1, a plurality of air-permeable nets 2 are fixedly connected to the lower side of the cabinet body 1, a left-right symmetrical shell body 3 is provided on the upper side of the cabinet body 1, two inner walls of the shell bodies 3 are fixedly connected to fixing frames 4, one end of the fixing frames 4 is fixedly connected to a dual-axis motor 5, one output end of the dual-axis motor 5 is fixedly connected to a fan blade 6, a dust cover 7 is sleeved on the outer wall of the shell body 3, a dust-proof net 8 is fixedly connected to the inner wall of the dust cover 7, a sleeve 9 is fixedly connected to the inside of the dust-proof net 8, a fixed shaft 10 is fixedly connected to the other output end of the dual-axis motor 5, the outer wall of the fixed shaft 10 is rotatably connected to the inner wall of the sleeve 9, and a cleaning component 11 is provided at one end of the fixed shaft 10; the cleaning component 11 comprises a mounting plate 1101, the lower surface of the mounting plate 1101 is fixedly connected to one end of the fixed shaft 10, and a brush 1102 is fixedly connected to the lower surface of the mounting plate 1101;

[0025] Specifically, in the internal thermal management process of the cabinet 1, the dual-axis motor 5 plays a key role. When it is necessary to discharge heat inside the cabinet 1, the dual-axis motor 5 is started first. The function of the dual-axis motor 5 is to drive the fan blades 6 to rotate, thereby realizing the introduction of cold air. This process is conducive to improving the thermal management effect inside the cabinet 1 and ensuring that the equipment operates in a suitable temperature environment. While introducing cold air, the breathable net 2 plays a role in discharging heat. Through the continuous rotation of the dual-axis motor 5, the heat can be effectively discharged and the temperature inside the cabinet 1 is reduced. This step is crucial to maintaining stable operation of the equipment, because high temperature may cause the performance of the equipment to decline or even damage. In addition, the dual-axis motor 5 is also responsible for driving the fixed shaft 10 to rotate. This process is conducive to further optimizing the thermal management effect and ensuring that the internal temperature of the cabinet 1 remains within a suitable range. Through the rotation of the fixed shaft 10, the brush 1102 on the lower surface of the mounting plate 1101 can be rotated accordingly. The main function of the brush 1102 is to prevent dust from remaining on the outer wall of the dustproof net 8. During the rotation of the brush 1102 , it can effectively clean the dust on the dustproof net 8 to prevent excessive dust accumulation from causing poor ventilation, thereby affecting the thermal management effect inside the cabinet 1 .

[0026] Reference Figure 3-4 A fixing box 12 is fixedly connected to the top of the inner wall of the cabinet 1, a hydraulic rod 13 is fixedly connected to the inner wall of the fixing box 12, and a rack plate 14 is fixedly connected to the output end of the hydraulic rod 13; a limiting rod 15 is fixedly connected to one side of the lower surface of the rack plate 14, and the outer wall of the limiting rod 15 is slidably connected to the inner wall of the fixing box 12; a rotating shaft 16 is rotatably connected inside the fixing box 12, and a gear 17 is fixedly connected to the outer wall of the rotating shaft 16, and the gear 17 is meshed and connected with the rack plate 14; an L-shaped connecting plate 18 is connected to the fixed plate on the lower surface of the rotating shaft 16, and a limiting column 19 is fixedly connected to one side of the L-shaped connecting plate 18; a protective door 20 is slidably connected to the outer wall of the limiting column 19, and one side of the protective door 20 is rotatably connected to one side of the outer wall of the cabinet 1;

[0027] Specifically, by starting the hydraulic rod 13, the effect of driving the rack plate 14 to slide inside the fixed box 12 can be achieved. This process is actually achieved through the movement of the hydraulic rod 13. In this process, the hydraulic rod 13 transmits force to the rack plate 14, so that it slides smoothly inside the fixed box 12. The close combination of the rack plate 14 and the fixed box 12 further drives the meshing rotation of the gear 17. This rotation method makes the entire mechanical equipment more stable and more efficient. The meshing rotation of the gear 17 not only provides powerful power for the equipment, but also makes the equipment more stable during operation, reducing noise and wear. Driven by the gear 17, the limiting column 19 inside the L-shaped connecting plate 18 can rotate smoothly. The role of the limiting column 19 is very important. It can ensure that the L-shaped connecting plate 18 always maintains the correct position and direction during operation. In this way, the protective door 20 can slide accurately according to the needs of the equipment. Finally, driven by the limiting column 19, the protective door 20 achieves the effect of opening and closing. This design enables the protective door 20 to remain stable during operation and to achieve flexible control. In practical applications, this design greatly improves the safety and reliability of the equipment and ensures the personal safety of the operator.

[0028] Reference Figure 3-4 A perspective window 21 is provided inside the protective door 20, a positioning groove 22 is provided inside the protective door 20, a sealing strip 23 is slidably connected inside the protective door 20, and the sealing strip 23 is slidably connected to the inner wall of the positioning groove 22;

[0029] Specifically, in the use of the protective door 20, the role of the sealing strip 23 is particularly important. By clinging to the outer wall of the cabinet 1, it effectively prevents external substances from entering the cabinet 1, ensuring the safety and cleanliness of the environment inside the cabinet. In the design of the sealing strip 23, a replaceable design is cleverly adopted, which greatly improves the convenience of use. When the protective door 20 needs to be sealed, the sealing strip 23 can be clinging to the outer wall of the cabinet 1. This design not only makes the sealing effect more outstanding, but also reduces the possibility of external pollutants entering the cabinet 1. In actual use, this design greatly improves the protective performance of the protective door 20 and meets the high requirements for sealing in various scenarios. However, as time goes by, the sealing strip 23 may need to be replaced due to wear or other reasons. At this time, the convenience of replacement considered by the designer is particularly practical. First, the user only needs to gently pull the sealing strip 23 to disengage it from the inner wall of the T-shaped positioning groove 22 to complete the replacement of the sealing strip 23. This design makes the replacement process of the sealing strip 23 simple and quick, greatly improving the user experience.

[0030] Working principle: when it is necessary to discharge heat from the inside of the cabinet 1, first start the dual-axis motor 5, and drive the fan blades 6 to rotate through the dual-axis motor 5, so as to achieve the effect of driving the cold air outside the cabinet 1 to be brought in, and then discharge the heat through the breathable net 2, and then through the rotation of the dual-axis motor 5, it is easy to drive the fixed shaft 10 to rotate, and then through the rotation of the fixed shaft 10, it is achieved to drive the brush 1102 on the lower surface of the mounting plate 1101 to rotate, and at this time, through the rotation of the brush 1102, the effect of preventing dust from remaining on the outer wall of the dustproof net 8 is achieved;

[0031] Secondly, when the protective door 20 of the inlet and outlet lines needs to be opened and closed, the hydraulic rod 13 is first started. Through the movement of the hydraulic rod 13, the rack plate 14 is driven to slide inside the fixed box 12. At this time, the fixed box 12 is meshed and rotated with the gear 17, so as to facilitate the rotation of the internal limit column 19 of the L-shaped connecting plate 18. The protective door 20 is driven to slide through the limit column 19, so as to achieve the effect of driving the protective door 20 to open and close;

[0032] Again, when the protective door 20 needs to be sealed, the sealing strip 23 is tightly attached to the outer wall of the cabinet 1, thereby achieving the effect of facilitating the sealing of the cabinet 1. When the sealing strip 23 needs to be replaced, the sealing strip 23 is first pulled away from the inner wall of the T-shaped positioning groove 22, thereby achieving the effect of facilitating the replacement of the sealing strip 23.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
