[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] In this embodiment, if Figures 1 to 3 As shown, the instrument cabinet for a thermal power plant includes a cabinet body 1, a heat dissipation component 2 and a vibration component 3. The cabinet body 1 has a front panel 11 and a rear panel 12 that are arranged opposite to each other. A first air outlet 111 is arranged at the bottom of the front panel 11, and a second air outlet 121 is arranged at the bottom of the rear panel 12. The first air outlet 111 and the second air outlet 121 are connected to each other; the heat dissipation component 2 is arranged at the outlet of the first air outlet 111 and the outlet of the second air outlet 121; the heat dissipation component 2 includes a filter component 21 and an air induction component 22, the filter component 21 is connected to the cabinet body 1, and the air induction component 22 is arranged on the filter component 21; the vibration component 3 is arranged on the filter component 21, and the vibration component 3 is used to drive the filter component 21 to vibrate.

[0028] Specifically, the cabinet 1 has an installation cavity, the instrument is arranged in the installation cavity, and the first air outlet 111 and the second air outlet 121 are both connected to the installation cavity. An opening and closing door is provided on the front panel 11 of the cabinet 1 to facilitate the installation and removal of the instrument. A handle is provided on the opening and closing door to facilitate the opening and closing of the door.

[0029] The cabinet body 1 in this embodiment is provided with a first air outlet 111 and a second air outlet 121 on the front panel 11 and the rear panel 12 which are relatively arranged. The first air outlet 111 and the second air outlet 121 are connected to each other. By providing an air induction component 22 at the first air outlet 111 and the second air outlet 121, the wind flow directions of the air induction components 22 at the first air outlet 111 and the second air outlet 121 are made the same, that is, external cold air enters from the first air outlet 111, and the hot air after heat dissipation of the instrument in the cabinet body 1 rises and is led out from the second air outlet 121, which speeds up the flow rate of the gas and is beneficial to improving the heat dissipation effect. In addition, by providing a vibrating member 3 on the filter component 21, the filter component 21 can be driven to vibrate, so that during the vibration of the filter component 21, dust on the filter component 21 is shaken off, and the blockage of the filter component 21 is reduced to ensure the ventilation effect.

[0030] In this embodiment, if Figure 3 and Figure 4 As shown, the air induced component 22 includes a fan 221 and a driving member 222. The fan 221 is rotatably arranged on the filter component 21 via a rotating shaft 225. The driving member 222 is arranged on the filter component 21 or the cabinet 1. The driving member 222 is connected to the rotating shaft 225, and the driving member 222 is used to drive the rotating shaft 225 to rotate a preset angle.

[0031] Specifically, the rotating shaft 225 is rotatably connected to the filter element 21, and the housing of the fan 221 is fixed to the rotating shaft 225. The specific installation method of the fan 221 can be adjusted according to the specific structure of the fan 221, which will not be described in detail here. The rotating shaft 225 can be rotatably connected to the filter element 21 through a bearing to reduce the friction force on the rotating shaft 225 when rotating. For example, the driving member 222 can be a motor, and the output shaft of the motor is connected to the rotating shaft 225.

[0032] It should be noted that when the temperature inside the cabinet 1 is too high, the fan 221 is driven to rotate by the driving member 222, so that the flow direction of the wind inside the cabinet 1 is reversed. The filter component 21 can blow off the dust under the action of the reverse wind flow, which is beneficial to improve the heat dissipation effect.

[0033] In this embodiment, if Figure 3 As shown, the air induction component 22 also includes a temperature sensor 223, which is disposed in the cabinet 1. The temperature sensor 223 is used to obtain temperature information in the cabinet 1. When the temperature in the cabinet 1 exceeds a preset value, the driving member 222 drives the rotating shaft 225 to rotate.

[0034] Specifically, the temperature sensor 223 and the motor in this embodiment are electrically connected to the controller, and the controller controls the driving member 222 to drive the rotating shaft 225 to rotate according to the temperature information obtained by the temperature sensor 223. Specifically, a temperature threshold can be set in the controller, and when the temperature is higher than the preset value, the driving member 222 drives the rotating shaft 225 to rotate. The connection mode and working principle of the temperature sensor 223 and the motor with the controller are conventional prior art and will not be described in detail here.

[0035] It can be understood that by setting a temperature sensor 223 in the cabinet 1, the temperature in the cabinet 1 can be monitored in real time. When the temperature in the cabinet 1 exceeds a preset value, the driving member 222 drives the rotating shaft 225 to rotate, so that the driving member 222 can respond in time, remove the dust on the filter component 21 in time, and improve the protection effect of the instruments in the cabinet 1.

[0036] In this embodiment, if Figure 4 and Figure 5 As shown, the air induced component 22 also includes a transmission member 224, and a plurality of fans 221 are provided. The plurality of fans 221 are arranged in sequence and spaced apart along the width direction of the cabinet 1. Each fan 221 is rotatably connected to the filter component 21 or the cabinet 1 through a rotating shaft 225, and two adjacent rotating shafts 225 are connected through a transmission member 224 so that the plurality of rotating shafts 225 rotate synchronously.

[0037] For example, the number of fans 221 can be set to two, three, four or five, etc., and the provision of multiple fans 221 is conducive to improving the air induction effect, thereby improving the heat dissipation effect. The specific number of fans 221 can be set according to the model of the fan 221, the size of the first air outlet 111 or the second air outlet 121, and is not limited here.

[0038] For example, the transmission member 224 includes a pulley and a transmission belt, one of the two adjacent rotating shafts 225 is provided with a first pulley, and the other is provided with a second pulley, and the transmission belt is wound around the first pulley and the second pulley, so that when one of the rotating shafts 225 rotates, the other rotating shaft 225 can be driven to rotate through the transmission member 224. The specific installation method of the transmission member 224 is a conventional prior art, and those skilled in the art can adjust it according to installation requirements, which will not be described in detail here.

[0039] Specifically, the fans 221 are rotatably connected to the filter component 21 or the cabinet 1 via the rotating shaft 225 , that is, the rotating shaft 225 can be connected to the cabinet 1 or to the filter component 21 , which is not limited here.

[0040] It is understandable that in this embodiment, by disposing a plurality of fans 221 at the first air outlet 111 and the second air outlet 121, the air induction effect is improved, thereby improving the heat dissipation effect. Adjacent rotating shafts 225 are connected by transmission members 224, so that the plurality of fans 221 can be driven by one power source, which is conducive to saving costs and reducing heat sources.

[0041] In this embodiment, if Figures 3 to 5 As shown, the filter component 21 includes a frame 211 and a filter 212. The frame 211 is arranged on the cabinet 1, and the frame 211 is L-shaped. The filter 212 is arranged at one end of the frame 211 and is located on the side of the cabinet 1 facing the outside. The filter 212 and the frame 211 form a U-shaped space. The rotating shaft 225 is rotatably connected to the frame 211, and the fan 221 is located in the U-shaped space.

[0042] Specifically, the filter screen 212 is detachably connected to the grid frame 211, so that the filter screen 212 can be removed and cleaned as needed to improve the heat dissipation effect.

[0043] It should be noted that the filter 212 and the grid 211 form a U-shaped space. When installing the filter component 21, the end of the filter 212 away from the grid 211 and the end of the grid 211 away from the filter 212 are connected to the cabinet 1 respectively, and the cabinet 1 blocks the opening side of the filter component 21, so that the fan 221 can be installed in the space formed by the filter component 21 and the cabinet 1, so that the fan 221 can be reliably protected and the safety of use can be improved. In addition, the rotating shaft 225 is rotatably connected to the grid 211, and the fan 221 can be removed from the cabinet 1 by disassembling the grid 211. At the same time, before the grid 211 is installed in the cabinet 1, the fan 221 can be pre-installed, which is conducive to improving the convenience of installing the fan 221.

[0044] In this embodiment, the filter screen 212 is arranged to be inclined relative to the horizontal plane, and the top of the filter screen 212 is inclined toward the inside of the cabinet 1 .

[0045] like Figure 4 As shown, the angle between the filter 212 and the horizontal plane is A, 45°≤A≤90°, for example, A can be 45°, 50°, 60°, 70°, 80° or 85°, etc., which is not limited here. If the inclination angle of the filter 212 is too small, it is not conducive to the inflow and outflow of airflow, and if the inclination angle of the filter 212 is too large, the filter component 21 will occupy a large space.

[0046] It can be understood that by tilting the top of the filter 212 toward the inside of the cabinet 1, the area of ​​the filter 212 can be increased, which helps to distribute the airflow more evenly and reduce local blockage, thereby helping to improve the heat dissipation effect.

[0047] In this embodiment, if Figure 3and Figure 4 As shown, the vibrating member 3 includes a driving rod 31 and an elastic force-bearing member 32 . The driving rod 31 is connected to the rotating shaft 225 to rotate with the rotating shaft 225 . The elastic force-bearing member 32 is arranged on the filter member 21 . The driving rod 31 is used to hit the elastic force-bearing member 32 during the rotation process with the rotating shaft 225 .

[0048] It can be understood that when the rotating shaft 225 rotates, it will drive the driving rod 31 to rotate. As the driving rod 31 rotates, the driving rod 31 presses against the elastic force-bearing member 32, causing the elastic force-bearing member 32 to be deformed. When the driving rod 31 moves away from the elastic force-bearing member 32, the elastic force-bearing member 32 is reset and the stored energy is transferred to the filter component 21, so that the filter 212 can vibrate accordingly, thereby allowing the dust on itself to fall off through vibration.

[0049] In this embodiment, a plurality of driving rods 31 are disposed on the outer circumference of the rotating shaft 225 .

[0050] Specifically, elastic force-bearing members 32 are provided on both side walls opposite to each other in the U-shaped space of the filter component 21. By increasing the number of the elastic force-bearing members 32, the number of times the elastic force-bearing members 32 are struck can be increased, which is beneficial to improving the vibration dust removal effect.

[0051] It should be noted that the number of driving rods 31 cannot affect the resetting of the elastic force-bearing member 32, so as to prevent the elastic force-bearing member 32 from being continuously abutted by the driving rod 31 and unable to release energy. Of course, the number of driving rods 31 can be set according to the size of the installation space, and is not limited here.

[0052] It is understandable that by providing a plurality of driving rods 31 , the frequency of the driving rods 31 striking the elastic force-bearing member 32 is increased, which is beneficial to improving the vibration effect, thereby helping to improve the dust removal effect of the filter component 21 .

[0053] In this embodiment, if Figure 3 As shown, a support plate 13 is provided in the cabinet 1 , and the support plate 13 is used to support the instrument. The support plate 13 is provided with ventilation holes 131 .

[0054] It can be understood that the first air outlet 111 and the second air outlet 121 in this embodiment are respectively arranged at the upper and lower ends of the cabinet 1. By setting ventilation holes 131 on the support plate 13 in the cabinet 1, the circulation of air between the first air outlet 111 and the second air outlet 121 can be facilitated.

[0055] In this embodiment, if Figure 1 and Figure 2 As shown, the instrument cabinet for a thermal power plant also includes a support frame 4, and the support member is arranged at the bottom of the cabinet body 1.

[0056] Specifically, the support frame 4 is a frame-type frame, which raises the bottom of the cabinet 1 , allowing air to circulate at the bottom, which is beneficial for heat dissipation of the bottom of the cabinet 1 .

[0057] When the instrument cabinet for a thermal power plant in this embodiment is used, the external air flow is introduced from the first air inlet through the first air inlet component 22, and the hot air after dissipating the heat for the instruments in the cabinet 1 rises and is led out from the second air outlet 121, thereby accelerating the flow rate of the gas and improving the heat dissipation effect. When the temperature sensor 223 detects that the temperature in the cabinet 1 exceeds the preset value, the driving member 222 drives the rotating shaft 225 to rotate, thereby turning the flow direction of the wind in the cabinet 1. The filter component 21 can blow off the dust under the action of the reverse wind flow, thereby improving the heat dissipation effect. At the same time, when the rotating shaft 225 rotates, it will drive the driving rod 31 to rotate. As the driving rod 31 rotates, the driving rod 31 presses against the elastic force-bearing member 32, causing the elastic force-bearing member 32 to be deformed. When the driving rod 31 moves away from the elastic force-bearing member 32, the elastic force-bearing member 32 is reset and the stored energy is transferred to the filter component 21, so that the filter 212 can vibrate accordingly, thereby causing the dust on itself to fall off through vibration, further improving the cleaning effect of the filter 212, and thus helping to improve the heat dissipation effect.
