[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the reference numbers and / or letters can be repeatedly referred to in different examples in the embodiments of the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0030] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0031] To solve the problems in the prior art, the present application provides a coating structure and an electric control cabinet, which can display the overheating point in the cabinet body, facilitate maintenance personnel to find the overheating point in the cabinet body in time, and thus ensure the safety of the electric control cabinet.

[0032] As shown in Figures 1-6 The present application provides a coating structure, which is arranged on at least one surface of the outer surface of the cabinet body 2, and includes: a temperature sensing layer 11 connected with the surface of the electric control cabinet, which is used to sense the temperature in the cabinet body 2; and a color developing layer 12 arranged on the side of the coating structure 1 away from the electric control cabinet; wherein the color developing layer 12 can produce color change according to the temperature sensed by the temperature sensing layer 11.

[0033] In the present application, the temperature in the cabinet body 2 is sensed by the temperature sensing layer 11, and color change is displayed by the color developing layer 12. When an overheating point occurs in the cabinet body 2, the corresponding area of the temperature sensing layer 11 is heated, and color change occurs in the corresponding area of the color developing layer 12, thereby realizing the display of the overheating point in the cabinet body 2, facilitating maintenance personnel to find the overheating point in the cabinet body 2 in time, and thus ensuring the safety of the electric control cabinet.

[0034] In the related art, the coating structure 1 on the outer surface of the cabinet body 2 only has the effects of protection and aesthetics, and does not have the effect of displaying the overheating point in the cabinet body 2, which leads to the problem that maintenance personnel cannot find the overheating point in the cabinet body 2 in time. If an overheating point occurs in the cabinet body 2, not only the performance of the coating structure 1 will be affected, but also there will be certain safety hazards, which is not conducive to the safety of the electric control cabinet.

[0035] As shown in Figure 2The temperature sensing layer 11 in the coating structure 1 is attached to the outer surface of the cabinet 2, so that the temperature change in the cabinet 2 can be well sensed, and the color change of the color developing layer 12 located on the outer layer of the coating structure 1 can be performed according to the temperature change. If a local overheating position is generated in the cabinet 2, the temperature sensing layer 11 will be heated, and the temperature after heating is transmitted to the color developing layer 12 to cause the color developing layer 12 to change color and form a color developing prompt position. Therefore, the maintenance personnel can timely find the overheating position in the cabinet 2, and quickly determine the position of the overheating position in the cabinet 2, without the need for the maintenance personnel to spend time and energy to find the overheating position in the cabinet 2, thereby improving the work efficiency. After the overheating position in the cabinet 2 is timely found, the maintenance personnel can timely take measures and investigate the overheating position to solve the problem of the overheating position, thereby avoiding the influence of the long-term overheating position of the coating structure 1 on the protection performance, and effectively avoiding the problem of safety hidden danger caused by the existence of the overheating position in the cabinet 2, and improving the safety of the use of the electric control cabinet.

[0036] Specifically, the color developing layer 12 can change color through a chemical reaction, and the color change can be a transition color change. The degree of the overheating position can be determined according to the specific situation of the color change. For example, the color of the color developing layer 12 under normal circumstances is green, and after heating, the color gradually changes to yellow, orange, and red. The temperature of the overheating position is determined by the final color of the color developing layer 12.

[0037] In some embodiments, when a local overheating position is generated in the cabinet 2, the temperature sensing layer 11 is heated at a position corresponding to the local overheating position, and the color developing layer 12 is color changed at a position corresponding to the local overheating position.

[0038] In the present application, the distribution position of the heating component in the cabinet 2 is different, so that the position of the overheating position is uncertain. When the overheating position occurs in the cabinet 2, only the region of the temperature sensing layer 11 corresponding to the overheating position is obviously heated, and the color developing layer 12 is color changed at a region corresponding to the overheating position in the cabinet 2. Not only can the occurrence of the overheating position in the cabinet 2 be timely found, but also the position of the overheating position can be accurately determined, so that the maintenance personnel can quickly determine the cause of the overheating position and take corresponding remedial measures.

[0039] In some embodiments, the coating structure 1 further comprises a waterproof coating 13 and a fireproof coating 14 arranged between the temperature sensing layer 11 and the color developing layer 12.

[0040] In the present application, the waterproof performance of the electric control cabinet is improved by the waterproof coating 13 to avoid the entry of external water into the cabinet 2, and the fireproof performance of the electric control cabinet is improved by the fireproof coating 14 to improve the safety of the use of the electric control cabinet.

[0041] Of course, the coating structure 1 can also select only the waterproof coating 13 or only the fireproof coating 14 according to actual needs.

[0042] In some embodiments, the coating structure 1 further comprises a ceramic insulation layer 15 arranged between the temperature sensing layer 11 and the color developing layer 12.

[0043] In the present application, the ceramic insulation layer 15 adopts a nano ceramic insulation material, which can ensure the heat dissipation effect and insulation effect of the electric control cabinet.

[0044] In some embodiments, the coating structure 1 further comprises a magnetic powder layer 16 arranged between the temperature sensing layer 11 and the color developing layer 12, and the magnetic powder layer 16 is adjacent to the color developing layer 12.

[0045] Specifically, the magnetic powder layer 16 is located on the inner side of the color developing layer 12 and does not affect the normal color development of the color developing layer 12. The magnetic powder layer 16 can also increase the stability of the entire coating structure 1.

[0046] The coating structure 1 senses the temperature in the cabinet 2 through the temperature sensing layer 11 and displays the color change through the color developing layer 12. When an overheating point occurs in the cabinet 2, the corresponding area of the temperature sensing layer 11 is heated, and the color developing layer 12 produces color change in the corresponding area, thereby realizing the display of the overheating point in the cabinet 2, facilitating the maintenance personnel to find the overheating point in the cabinet 2 in time, and thereby ensuring the safety of the electric control cabinet.

[0047] Figure 3 A structure schematic diagram of an electric control cabinet provided by an embodiment of the present application is shown.

[0048] As shown in Figure 3 An electric control cabinet is provided by an embodiment of the present application, which comprises a cabinet 2 and the above-mentioned coating structure 1.

[0049] In the present application, by arranging the above-mentioned coating structure 1 on the outer surface of the cabinet 2, the temperature in the cabinet 2 can be sensed through the temperature sensing layer 11. When an overheating point occurs in the cabinet 2, the corresponding area of the temperature sensing layer 11 is heated, and the color developing layer 12 produces color change in the corresponding area, thereby realizing the display of the overheating point in the cabinet 2, facilitating the maintenance personnel to find the overheating point in the cabinet 2 in time, and thereby ensuring the safety of the electric control cabinet.

[0050] As shown in Figure 4 In an embodiment, the electric control cabinet further comprises an electric heating detection plate 3 arranged in the cabinet 2, and the electric heating detection plate 3 is used to heat at least part of the area of the coating structure 1.

[0051] In the application, the electric heating detection plate 3 is arranged in the cabinet body 2, and is used to heat the coating structure 1. When the electric control cabinet needs to be maintained, the electric heating detection plate 3 is started, the coating structure 1 is heated by the electric heating detection plate 3, the temperature of the temperature sensing layer 11 of the coating structure 1 is raised, and the color changing layer 12 is discolored. The intact area of the coating structure 1 can be normally discolored. If a certain area of the coating structure 1 cannot be normally discolored, it is proved that the coating structure 1 is damaged in this area, the damaged range of the coating structure 1 can be quickly found out, so that the use function and service life of the coating structure 1 of the electric control cabinet can be further guaranteed.

[0052] Specifically, the electric heating detection plate 3 can be arranged only at the part of the coating structure 1 which is easy to be damaged, or can heat and raise the temperature of the entire coating structure 1. When the electric heating plate works, the entire area of the coating structure 1 can be heated, so that the area without discoloration in the area can be determined as the damaged range of the coating.

[0053] Further, when the electric heating detection plate 3 heats the coating structure 1, the temperature of the temperature sensing layer 11 of the coating structure 1 is raised, and the color changing layer 12 generates color change in the area corresponding to the temperature sensing layer 11 after being raised in temperature.

[0054] In the application, the electric heating detection plate 3 heats an area of the coating structure 1, and is mainly used for detecting the integrity of the coating structure 1. Under normal circumstances, the coating structure 1 will be heated in the entire heating area and make the color changing layer 12 discolored. If a part of the area is not discolored, it is proved that the area without discoloration is damaged.

[0055] Specifically, the electric heating detection plate 3 is started only when the integrity of the coating structure 1 needs to be detected, and is in an off state in normal times, so as not to affect the display of the coating structure 1 on the overheated point of the electric control cabinet.

[0056] As shown in FIG. 1, Figures 5-6 In another embodiment, the coating structure 1 further comprises a magnetic powder layer 16 arranged between the temperature sensing layer 11 and the color changing layer 12, and the magnetic powder layer 16 is adjacent to the color changing layer 12. The electric control cabinet further comprises a detection storage frame 4 arranged outside the coating structure 1, and the detection storage frame 4 movably arranges a magnetic block particle 5, and the magnetic block particle 5 is magnetically attracted to the magnetic powder layer 16.

[0057] In the present application, the magnetic block particles 5 in the detection storage frame 4 are magnetically attracted to the magnetic powder layer 16 of the coating structure 1 by arranging the detection storage frame 4 outside the coating structure 1. Since the coating structure 1 is a whole structure, if it is damaged, the multiple layers of the coating structure 1 will be damaged. Therefore, when the coating structure 1 is intact, the magnetic block particles 5 are adsorbed to the magnetic powder layer 16. If the coating structure 1 is damaged at a certain position, the magnetic powder layer 16 at the damaged position is also damaged, so the magnetic block particles 5 at the damaged position cannot be adsorbed. Thus, the integrity of the coating structure 1 can be checked, which is beneficial to ensure the use function and service life of the coating structure 1.

[0058] Specifically, the detection storage frame 4 is made of transparent material, so that the distribution of the magnetic block particles 5 inside can be seen.

[0059] In some embodiments, an electromagnetic inner plate 6 is arranged in the detection storage frame 4, which is used to uniformly distribute the magnetic block particles 5 in the detection storage frame 4 when powered on. The electromagnetic inner plate 6 is a flat plate structure and is parallel to the surface of the cabinet 2. When powered on, the magnetic block particles 5 can be uniformly distributed.

[0060] In the present application, the electromagnetic inner plate 6 is powered on to generate magnetism and make the magnetic block particles 5 in the detection storage frame 4 uniformly distributed. Then, the detection storage frame 4 is placed at the position outside the coating structure 1 to be detected. The magnetic block particles 5 are magnetically attracted to the magnetic powder layer 16 of the coating structure 1. The electromagnetic inner plate 6 is powered off. At this time, only the magnetic powder layer 16 adsorbs and fixes the magnetic block particles 5. If the magnetic block particles 5 cannot be fixed, it proves that the coating structure 1 at this position is damaged.

[0061] Specifically, the detection storage frame 4 can be fixedly arranged outside the cabinet 2, or temporarily placed at the position to be detected when detection is needed. After checking one position, the electromagnetic inner plate 6 is powered on to make the magnetic block particles 5 uniformly distributed. Then, the next coating structure 1 of the electric control cabinet is detected in the same way.
