[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0025] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0026] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] The water pipes connecting the inverter body to the external water circulation system will be damaged during long-term use due to the year-round operation, seasonal hot and cold alternation, and thermal expansion and contraction effects, causing the water flow and antifreeze in the pipes to leak out. Since there is no external equipment to block or intercept them in time, these liquids will flow freely and eventually reach the control cabinet and penetrate into it.

[0028] There are many electrical equipment gathered inside the control cabinet. The leaking water and antifreeze pose a serious threat to its operation. They will not only corrode the circuit structure and cause equipment damage, but may also cause short circuits inside the control cabinet and cause fires, posing a major safety hazard.

[0029] In order to solve the above technical defects, the inventor provides a mechanism and method for monitoring the permeation of a fluid circulation bearing component in a frequency converter.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: First, as Figure 1-Figure 7As shown, an embodiment of the present invention provides a permeation monitoring mechanism for a fluid circulation bearing component in a frequency converter, comprising a supporting device 1, on which are provided a monitoring device 2, an anti-permeation device 3, a dehumidification device 4 and a control device 5, wherein the monitoring device 2, the anti-permeation device 3 and the dehumidification device 4 are all electrically connected to the control device 5; wherein the monitoring device 2 is used to monitor the ambient humidity around the control cabinet 7, one end of the anti-permeation device 3 is connected to the supporting device 1, and the other end is installed at the connection between the frequency converter and the external pipeline; one end of the dehumidification device 4 is connected to the supporting device 1, and the other end is located on the control cabinet 7. As can be seen from the figure, the supporting device 1 in the monitoring mechanism is installed on the top of the control cabinet 7 through the clamping device 6, so that the dehumidification device 4 faces the control cabinet 7; the monitoring device 2 is installed on the top of the supporting device 1, and monitors the temperature and humidity around the control cabinet 7 by rotating; and the anti-permeation device 3 is installed at the connection between the inverter body and the external pipeline, which can obtain the status information of the connection between the inverter body and the external pipeline, and the status information includes two states: leakage and no leakage; when the connection of the external pipeline infiltrates water or antifreeze, the anti-permeation device 3 can be used to effectively block it and reduce the content of the outward penetration; secondly, when the infiltrated water or antifreeze spreads outward, the monitoring device 2 is used to monitor the ambient humidity around the control cabinet 7, and the dehumidification device 4 is started according to the monitoring results to perform dehumidification operations on the inside and outside of the control cabinet 7, which effectively avoids the problem of malfunction of the control cabinet 7. Figure 1-Figure 4 As shown, the anti-permeation device 3 includes a suspension component and an anti-permeation component. Since multiple external pipelines are installed on the inverter body, multiple suspension components can be installed around the support device 1, or on two opposite sides to ensure that the penetration situation of each pipeline can be connected; when the suspension components are installed on the opposite sides of the support device 1, multiple suspension components are arranged along the length of the support device 1 to correspond to the number of external pipelines on the inverter body, and an anti-permeation component is installed on each suspension component; the suspension component includes a hanging ring 301, and a hanging rope 302 is movably connected to the hanging ring 301, and the end of the hanging rope 302 is connected to the anti-permeation component. The installation of the anti-permeation component can monitor whether there is a penetration problem at the pipeline connection at the first time. If a penetration problem is detected, the anti-permeation component can promptly block the fluid at the penetration point to reduce the amount of water that seeps out. Figure 5As shown, the anti-permeation component includes a blocking tube 303, which is sleeved on the outside of the connection to wrap the pipeline connection; a blocking piece 3031 and a water intrusion sensor 3032 are provided on the inner side of the blocking tube 303. The setting of the water intrusion sensor 3032 can timely monitor whether there is a problem of water flow or antifreeze liquid penetration at the pipeline connection, and transmit the monitoring signal to the control device 5; in the process of signal transmission, the blocking piece 3031 located on the inner side of the blocking tube 303 can absorb the infiltrated water flow and reduce the flow rate of water flowing outward; at the same time, in the process of water flowing outward, it will affect the environmental humidity around the control cabinet 7. When the monitoring device 2 detects that the environmental humidity around the control cabinet 7 exceeds the preset value, the monitoring device 2 transmits the signal to the control device 5; when the control device 5 receives the signal transmitted by the water intrusion sensor 3032, it immediately controls the driving member 304 to drive the blocking plate 306 to Move so that the sealing plate 306 is against the outside of the pipeline connection, and since the cross-section of the sealing plate 306 is an arc, the sealing plate 306 is more compatible with the external pipeline. In this solution, the driving member 304 is preferably an electric push rod; in the process of the driving member 304 driving the sealing plate 306 to move, since a movable hole is provided on the outside of the sealing tube 303, the driving end of the driving member 304 can smoothly pass through the movable hole, so that the sealing plate 306 can block the infiltration at the pipeline connection, and support rods 305 are installed on the opposite sides of the driving member 304, and the ends of the support rods 305 are connected to the outside of the sealing tube 303; in this solution, in one embodiment, the sealing member 3031 is preferably a sponge; in another embodiment, the sealing member 3031 is preferably a diatom pad, and the sponge or diatom pad is wrapped around the outside of the connection. During the blocking process, the sponge or diatom pad can absorb the infiltrated water or antifreeze. When the control device 5 receives the signal transmitted by the monitoring device 2, the dehumidification device 4 is activated, and the dehumidification device 4 performs a dehumidification operation on the inside and outside of the control cabinet 7 to prevent the infiltrated water or antifreeze from causing harm to the electrical equipment inside the control cabinet 7. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the dehumidification device 4 includes a mounting plate 401, and the mounting plate 401 is an L-shaped structure, one end of which is fixed on the supporting device 1, and the other end extends outward and bends toward the control cabinet 7. A vent is provided on the top of the mounting plate 401, and a dehumidification unit 402 is installed on the vent. In order to achieve the best dehumidification effect, guide plates 403 are provided on opposite sides of the mounting plate 401, and the guide plates 403 are perpendicular to the ground. The ends of the guide plates 403 extend to the bottom of the control cabinet 7. In one embodiment, the dehumidification unit 402 Preferably, it is a fan. When a fan is used for dehumidification, the hot air generated by the fan flows toward the bottom of the control cabinet 7. During the flow, under the action of the two guide plates 403, the hot air can flow slowly along the outer side of the control cabinet 7, evaporating the moisture or water outside the control cabinet 7. At the same time, during the slow flow of the hot air on the outer side of the control cabinet 7, part of the hot air passes through the gap of the control cabinet 7 and enters the inside of the control cabinet 7, dehumidifying the inside of the control cabinet 7. In another embodiment, the dehumidification unit 402 is preferably a dehumidifier. Figure 1 As shown, the monitoring device 2 includes a base 201, which is arranged on the top of the supporting device 1, and a motor 202 is installed in the base 201, and the driving end of the motor 202 is connected to a long rod 203, and the long rod 203 and the driving end of the motor 202 are axially overlapped; a cross bar 204 is installed horizontally on the top of the long rod 203, and temperature and humidity sensors 205 are fixedly installed at both ends of the cross bar 204. Both temperature and humidity sensors 205 are used to monitor the ambient temperature and humidity conditions around the control cabinet 7. By setting two temperature and humidity sensors 205, the accuracy of temperature and humidity data monitoring can be ensured. Secondly, the introduction of the motor 202 enables the long rod 203 and the cross bar 204 to rotate or adjust their positions as needed, thereby realizing automatic monitoring of temperature and humidity in different areas or heights. This automatic monitoring capability not only improves the efficiency and accuracy of monitoring, but also reduces manual intervention and reduces labor costs. The temperature and humidity sensors 205 fixedly installed at both ends of the cross bar 204 can simultaneously monitor the temperature and humidity data of two different positions, thereby improving the comprehensiveness and accuracy of monitoring. The design of the motor 202 and the long rod 203 makes the mechanism flexible and can adjust the monitoring position according to actual needs. In addition, the mechanism can also add more sensors or functional modules as needed to expand its monitoring range and functions. Figure 1 , Figure 6 and Figure 7As shown, the support device 1 is a support platform, and legs 101 are installed around the bottom of the support platform. The four legs 101 are in contact with the top of the control cabinet 7, so that the support platform is stably placed; at the same time, in order to ensure the reliability of the support platform during long-term work, clamping devices 6 are installed on the opposite sides of the support platform, and the clamping device 6 includes a connecting plate 601. There are four connecting plates 601, and every two connecting plates 601 form a group. The two groups of connecting plates 601 are arranged on the opposite sides of the support device 1. A spring clip 602 is installed on each group of connecting plates 601. A hanging plate 603 is provided at the end of the spring clip 602. The cross-section of the hanging plate 603 is arc-shaped, and the end of the hanging plate 603 is in contact with the groove on the outside of the control cabinet 7, so that the clamping device 6 clamps the support device 1 and fixes it to the top of the support device 1.

[0031] In a second aspect, an embodiment of the present invention provides a method for monitoring the permeation of a fluid circulation bearing component in a frequency converter, wherein the method is performed using the monitoring mechanism as described above. Figure 8 As shown, including: S101. Obtain the status information of the connection between the inverter and the external pipeline, as well as the humidity data of the environment around the inverter; illustratively, firstly, the status information operation value and the ambient temperature and humidity data operation value at the pipeline connector are preset by the control device 5, and when the status information and the temperature and humidity data values ​​are respectively obtained by using the water intrusion sensor 3032 and the temperature and humidity sensor 205, the obtained status information operation value and the temperature and humidity data value are then compared with the preset status information operation value and the preset temperature and humidity data operation value.

[0032] S102: Based on the acquired state information and ambient temperature and humidity data, determine whether to perform a dehumidification operation on the control cabinet. For example, when the control device 5 determines that the acquired state information and temperature and humidity data values ​​are greater than the preset state information operation value and the preset temperature and humidity data operation value, the anti-infiltration device 3 and the dehumidification device 4 are controlled to perform the operation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
