[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] like Figures 1 to 10 As shown, an electric control cabinet of the present invention includes a housing assembly 1 , the housing assembly 1 includes a cabinet body 101 , an installation assembly 2 arranged inside the cabinet body 101 , and a heat dissipation adjustment assembly 3 arranged on one side of the installation assembly 2 .

[0023] like Figure 2 , Figure 3As shown, a cabinet door 102 is provided on one side of the cabinet body 101, a ventilation frame 103 is provided above the cabinet body 101, a cooling fan 104 is provided at one end of the cabinet body 101 close to the ventilation frame 103, a plurality of exhaust holes 105 are provided on the surface of the ventilation frame 103, and air inlet grilles 106 are provided on both sides of the cabinet body 101.

[0024] like Figure 1 , Figure 5 As shown, the installation component 2 includes a fixing frame 201, which is connected to the inner wall of the cabinet body 101, and damping springs 202 are arranged at the four corners of the surface of the fixing frame 201. A mounting frame 203 is arranged at the end of the fixing frame 201 away from the damping spring 202, and a movable sleeve 204 is arranged at the end of the mounting frame 203 close to the fixing frame 201. A limiting column 205 is arranged at the end of the movable sleeve 204 away from the mounting frame 203, and a limiting groove is provided at the position where the movable sleeve 204 is connected to the limiting column 205, and the end of the limiting column 205 away from the movable sleeve 204 is connected to the fixing frame 201.

[0025] When in use, firstly, the electrical components are fixed on the mounting frame 203 by means of bolts. In order to ensure the stability of the electrical components in the cabinet body 101 during use, a mounting assembly 2 is provided to buffer and reduce vibration. When the cabinet body 101 as a whole vibrates under the action of external wind force, the mounting frame 203 on the fixed frame 201 is buffered under the action of the vibration-damping spring 202. During this process, the movable sleeve 204 slides in the vertical direction along the limiting column 205 to prevent the mounting frame 203 from shifting in the horizontal direction, thereby achieving the purpose of buffering and protecting the electrical components on the mounting frame 203.

[0026] In addition, during construction, the crane is controlled by the electrical components in the electrical control cabinet to complete the operation. Since the electrical components will generate heat when working, the cooling fan 104 and the air inlet grille 106 are used to perform basic heat dissipation. Under the action of the cooling fan 104, the outside air enters the cabinet body 101 from the air inlet grille 106 and performs heat exchange. Then the air in the cabinet body 101 passes through the ventilation rack 103 and is discharged from the exhaust hole 105. In this process, the air absorbs the heat in the cabinet body 101 and discharges it to the outside, thereby accelerating the circulation between the cabinet body 101 and the external air, and achieving the purpose of heat dissipation of the electrical components in the cabinet body 101.

[0027] The inventors found that due to the different temperatures at different locations within the cabinet body 101, it is impossible to make timely adjustments based on the temperature differences, resulting in the inability to quickly achieve effective heat dissipation; and the air circulation at the locations of the electrical components within the cabinet body 101 is poor, resulting in heat accumulation and causing local high temperatures; the cabinet body 101 will vibrate under the action of external wind, and if the external wind is too strong, the circuit connections on the electrical components inside the cabinet body 101 will become loose or even broken, affecting normal operation.

[0028] In order to solve the above problems, the electric control cabinet also includes: like Figure 8 , Fig. 9 As shown, an air hole 206 is provided at one end of the movable sleeve 204 away from the limiting column 205, a plurality of guide holes 208 are provided on both sides of the mounting frame 203, and the guide holes 208 are provided at one end of the mounting frame 203 close to the fixed frame 201, and an elastic hose 207 is provided at the center of the surface of the movable sleeve 204, and a control valve is provided inside the elastic hose 207.

[0029] like Figures 6 to 10 As shown, the heat dissipation adjustment component 3 includes a heat dissipation frame 301, which is arranged on one side of the fixing frame 201, and a plurality of heat dissipation plates 302 are arranged at intervals on the surface of the heat dissipation frame 301, and a memory spring 303 is arranged between two adjacent heat dissipation plates 302, and a circular hole is opened at the position where the heat dissipation plate 302 is connected to the heat dissipation frame 301, and a plurality of positioning frames 304 are arranged above the heat dissipation frame 301, and an elastic hose 207 passes through the mounting frame 203 and extends to the interior of the positioning frame 304, and a cavity is arranged inside the positioning frame 304, and one end of the elastic hose 207 away from the movable sleeve 204 is connected to the cavity, and a movable rod 305 is arranged inside the cavity, and a placement frame 306 is arranged at one end of the movable rod 305 close to the mounting frame 203, and an elastic member 307 is arranged on the side of the placement frame 306 away from the movable rod 305.

[0030] A compression spring 308 is arranged on the surface of the movable rod 305 . An annular ring is arranged on the surface of the movable rod 305 . The compression spring 308 is arranged on one end of the annular ring close to the placement rack 306 . The end of the compression spring 308 away from the movable rod 305 is connected to the placement rack 306 .

[0031] It is worth noting that the surface of the mounting frame 203 is provided with a through hole compatible with the air hole 206. In the initial state, the control valve is in a closed state, and the gas in the movable sleeve 204 passes through the air hole 206 and is discharged along the through hole. The gas in the movable sleeve 204 will not enter the cavity on the positioning frame 304 through the elastic hose 207.

[0032] like Figure 7As shown, wedge blocks 309 are provided on both sides of the elastic member 307, a wedge rod 310 adapted to the wedge block 309 is provided on the side of the wedge block 309 away from the mounting frame 203, an adjustment plate 311 is hingedly provided on the end of the wedge rod 310 away from the wedge block 309, a first connecting spring 312 is provided on the end of the wedge block 309 away from the elastic member 307, the end of the first connecting spring 312 away from the wedge block 309 is connected to the positioning frame 304, a moving groove is provided at the position where the positioning frame 304 is connected to the wedge block 309, a second connecting spring 313 is provided on the surface of the wedge rod 310, and the end of the second connecting spring 313 close to the adjustment plate 311 is connected to the positioning frame 304.

[0033] like Figure 2 , Figure 6 As shown, a ventilation slot matched with the adjustment plate 311 is provided on the surface of the cabinet body 101 , and a rotating shaft 314 is provided inside the adjustment plate 311 , and the adjustment plate 311 is movably connected to the ventilation slot via the rotating shaft 314 .

[0034] Since the heat dissipation efficiency in the cabinet body 101 is poor, and the temperatures at different positions in the cabinet body 101 are different, and the air circulation at the positions of the electrical components in the cabinet body 101 is poor, heat accumulation causes local high temperature, so the heat dissipation effect is improved by setting a heat dissipation adjustment component 3. In the heat dissipation process, the heat generated by the electrical components when they are working is transferred to the mounting frame 203 under the action of heat transfer. At this time, multiple heat dissipation plates 302 are set to absorb the heat on the surface of the mounting frame 203 to increase the heat dissipation area. Under the action of the heat dissipation fan 104, the air in the cabinet body 101 flows through the heat dissipation plate 302 to take away the heat on the heat dissipation plate 302, thereby achieving heat dissipation.

[0035] At the same time, since the electrical components installed on the mounting frame 203 are different, the heat emitted by the electrical components when working is also different, resulting in different temperatures at different positions on the mounting frame 203. If a local position of the mounting frame 203 is overheated, it indicates that the heat emitted by the electrical components at this position when working is too high. At this time, since the memory spring 303 has the characteristics of thermal contraction and thermal expansion, the memory spring 303 located at a higher temperature position of the mounting frame 203 shrinks, and the interval between the two adjacent heat sinks 302 at this position is shortened, that is, the number of heat sinks 302 at this position is increased, thereby increasing the heat dissipation area, improving the heat dissipation effect, and thus achieving rapid heat dissipation.

[0036] In the above process, if there is too much heat in this area, it will cause the temperature to be too high, and rapid heat dissipation cannot be achieved only through the heat sink 302, which indicates that the heat dissipation demand required in this area is large. At this time, the thermal expansion material inside the elastic member 307 expands due to the heat, causing the elastic member 307 to increase in volume and squeeze the wedge block 309, the first connecting spring 312 is compressed, and the wedge block 309 moves away from the elastic member 307. During this process, the second connecting spring 313 is compressed, and the wedge rod 310 is squeezed by the wedge block 309 and moves toward the adjustment plate 311. Under the push of the wedge rod 310, the adjustment plate 311 rotates in the ventilation slot with the rotating shaft 314 as the center, thereby increasing the opening area between the adjustment plate 311 and the ventilation slot, increasing the ventilation degree, and allowing the outside air to blow toward the heat sink 302 along the adjustment plate 311, accelerating the heat exchange between the air and the heat sink 302, allowing the air to take away the heat on the heat sink 302, and improving the heat dissipation speed.

[0037] When the temperature rises, the greater the deformation of the thermal expansion material inside the elastic member 307, the larger the volume of the elastic member 307, the greater the squeezing force exerted by the elastic member 307 on the wedge block 309, and under the action of the wedge block 309 and the wedge rod 310, the greater the displacement of the wedge rod 310 along the moving groove on the positioning frame 304, that is, the greater the force of the wedge rod 310 on the adjustment plate 311, the larger the opening area between the adjustment plate 311 and the ventilation groove, the greater the amount of outside air entering the cabinet body 101, the greater the degree of air circulation in the cabinet body 101, and the stronger the heat dissipation capacity.

[0038] Similarly, when the temperature drops, the deformation degree of the thermal expansion material inside the elastic member 307 decreases, the volume of the elastic member 307 decreases, and the squeezing force of the wedge block 309 by the elastic member 307 decreases. Under the action of the wedge block 309 and the wedge rod 310, the wedge rod 310 moves toward the direction close to the wedge block 309, that is, the force of the wedge rod 310 on the adjustment plate 311 is reduced, and the opening area between the adjustment plate 311 and the ventilation slot is reduced. When the temperature drops, the electrical components inside the cabinet body 101 are protected by reducing the ventilation area.

[0039] In addition, by setting up the elastic member 307, the wedge block 309, the wedge rod 310, the adjustment plate 311 and other structures, the inclination angle of the adjustment plate 311 can be controlled in real time according to different temperatures, and then the ventilation volume between the adjustment plate 311 and the ventilation slot can be adjusted. Since the temperatures at different positions are different, the inclination angle of the adjustment plate 311 and the ventilation volume between the adjustment plate 311 and the ventilation slot are different, that is, the angle and volume of air entering the adjustment plate 311 at different positions in the cabinet body 101 are different, which is convenient for enhancing the turbulence effect of the air in the cabinet body 101 and enhancing the fluidity of the air. It can not only avoid the dead corners in the cabinet body 101 causing local excessive temperature, but also avoid dust accumulation affecting heat dissipation.

[0040] It is worth mentioning that the memory spring 303 has the characteristics of thermal contraction and thermal expansion. The memory spring 303 is a spring made using the characteristics of shape memory alloy, that is, when the temperature rises, the memory spring 303 will shorten until it returns to its original shape, and when the temperature drops, the memory spring 303 will stretch. In addition, the elastic member 307 is provided with thermal expansion material inside. When the temperature rises, the thermal expansion material has the characteristic of increasing its volume due to thermal expansion.

[0041] During crane construction, the cabinet body 101 vibrates as a whole under the action of external wind. In order to ensure the stability of the electrical components in the cabinet body 101 during use, a mounting assembly 2 is provided to provide buffering and vibration reduction. Specifically, when the vibration-damping spring 202 is stretched, the mounting frame 203 drives the movable sleeve 204 to move in the vertical direction away from the fixed frame 201. At this time, the space enclosed by the movable sleeve 204 and the limiting column 205 increases, forming a negative pressure, thereby drawing the gas in the cabinet body 101 into the movable sleeve 204 through the air hole 206. When the vibration-damping spring 202 is compressed, the mounting frame 203 drives the movable sleeve 204 to move in the vertical direction toward the fixed frame 201. At this time, the space enclosed by the movable sleeve 204 and the limiting column 205 is reduced, and the limiting column 205 squeezes the gas in the movable sleeve 204, so that the gas is discharged through the air hole 206 and sprayed on the electronic components and the heat sink 302. Due to the external wind force, the cabinet body 101 vibrates continuously, so that the mounting frame 203 drives the movable sleeve 204 to reciprocate in the vertical direction. During this process, the movable sleeve 204 and the limiting column 205 cooperate to perform reciprocating air extraction and exhaust, which can not only blow away the dust accumulated on the surface of the electronic components and the heat sink 302 to prevent dust accumulation from affecting the heat dissipation efficiency, but also speed up the air flow around the electronic components and the heat sink 302 to avoid poor circulation causing heat accumulation and affecting heat dissipation.

[0042] At the same time, when the mounting frame 203 reciprocates in the vertical direction, the mounting frame 203 will disturb the surrounding air. The air disturbance helps to make the surrounding temperature uniform, and the air forms a jet when flowing through the guide holes 208 on the mounting frame 203, thereby accelerating the air flow and improving the heat transfer efficiency.

[0043] However, when the external wind force is too strong, the cabinet body 101 vibrates greatly, which may cause the circuit connection on the electrical components on the surface of the mounting frame 203 to loosen or even break. At this time, the mounting frame 203 on the fixed frame 201 is buffered by the damping spring 202, and the mounting frame 203 drives the movable sleeve 204 to reciprocate in the vertical direction. During this process, the movable sleeve 204 and the limit column 205 cooperate to perform reciprocating air extraction and exhaust. When the mounting frame 203 drives the movable sleeve 204 to move in the vertical direction away from the fixed frame 201, the movable sleeve 204 04 and the limit column 205 cooperate to pump air, and the gas enters the movable sleeve 204 through the air hole 206. The greater the displacement of the movable sleeve 204, the greater the amount of gas pumped into the movable sleeve 204. Since the movable sleeve 204 is provided with a displacement sensor, the vibration amplitude of the mounting frame 203 can be obtained by detecting the displacement of the movable sleeve 204 through the displacement sensor. The greater the displacement of the movable sleeve 204, the greater the vibration amplitude of the mounting frame 203, so as to judge whether the electrical components are working in a normal state according to the vibration amplitude of the mounting frame 203.

[0044] It is worth mentioning that a displacement sensor is provided on the movable sleeve 204, through which the movement state of the movable sleeve 204 can be monitored, and whether the electrical components on the mounting bracket 203 are in a vibrating state and the degree of vibration can be reflected. When the mounting bracket 203 moves in the vertical direction, there will be no motion interference between the mounting bracket 203 and the heat sink 302.

[0045] When the displacement sensor detects that the displacement of the movable sleeve 204 is within the standard range, it indicates that the vibration amplitude of the mounting frame 203 will not cause damage to the electrical components. In this process, due to the increase in temperature, the thermal expansion material inside the elastic member 307 expands due to the heat, and the volume of the elastic member 307 increases to squeeze the mounting frame 203. The elastic member 307 deforms to increase the contact area with the mounting frame 203, thereby causing resistance to the vertical movement of the mounting frame 203 and reducing the vibration degree of the mounting frame 203.

[0046] When the displacement sensor detects that the displacement of the movable sleeve 204 exceeds the standard range, it indicates that the vibration amplitude of the mounting frame 203 is large, which will affect the normal operation of the electrical components. The larger the displacement of the movable sleeve 204, the larger the amount of gas drawn into the movable sleeve 204. When the damping spring 202 is compressed, the controller opens the control valve. At this time, the space enclosed by the movable sleeve 204 and the limiting column 205 is reduced, and the limiting column 205 squeezes the gas in the movable sleeve 204. At this time, part of the gas in the movable sleeve 204 enters the cavity of the positioning frame 304 through the elastic hose 207. Under the action of the gas, the compression spring 308 is stretched, and the gas pushes the movable rod 305, the placement frame 306 and the elastic member 307 to move in the direction close to the mounting frame 203, thereby increasing the squeezing force of the elastic member 307 on the mounting frame 203, so that the mounting frame 203 is resisted by the elastic member 307 during movement, thereby achieving the purpose of reducing the vibration amplitude of the mounting frame 203.

[0047] According to the difference between the displacement of the movable sleeve 204 and the highest threshold value of the standard range, the amount of gas introduced into the cavity is controlled, the displacement of the movable rod 305 in the cavity is adjusted, and then the resistance of the mounting frame 203 to the elastic member 307 during movement is adjusted, so that the displacement of the movable sleeve 204 is restored to within the standard range.

[0048] The present invention discloses a method for using an electric control cabinet, and the specific steps of the method are as follows: S1: First, the electrical components are fixedly mounted on the mounting frame 203 in the mounting assembly 2, and are buffered by the damping spring 202 to prevent the electrical components inside the cabinet body 101 from vibrating and affecting normal operation due to excessive external wind force; S2: Then the heat inside the cabinet body 101 is dissipated by the heat dissipation adjustment component 3, and the heat dissipated by the electrical components on the mounting frame 203 is absorbed by the heat dissipation plate 302 for conduction dissipation; S3: Finally, according to the different temperatures at different positions in the cabinet body 101, the heat dissipation adjustment component 3 is adjusted in real time to quickly dissipate heat to ensure the normal operation of the electrical components.

[0049] The present invention discloses an application of an electric control cabinet in crane construction, which is specifically applied to the situation in which the heat emitted by electrical components during operation during crane construction causes the internal temperature of the electric control cabinet to be too high, or the electrical components inside the electric control cabinet vibrate due to excessive external wind force, affecting normal operation. During the crane construction process, multiple electrical components of the crane are centrally controlled by the electric control cabinet, thereby achieving flexible and reliable coordinated work among the components. In order to ensure precise control of the crane and improve operating efficiency and safety, the electric control cabinet needs to be heat-dissipated and vibration-reduced to ensure the normal operation of the electrical components.
