A rotating shaft 202d is rotatably connected through the housing 101, and a side wall of the rotating shaft 202d is fixedly connected to the grid 202e. 03 includes a rotating base 203a fixedly connected to one side of the moving frame 201d, a rotating rod 203b is rotatably connected in the rotating base 203a, a connecting shaft 203d is rotatably connected to one side of the rotating rod 203b, a fitting groove 203c is provided on one side of the traction tooth plate 202a, and the connecting shaft 203d extends into the fitting groove 203c, and the linkage component 204 includes a driving gear 204a fixedly connected to the side wall of the rotating shaft 202d on one side, and a transmission gear 204b is fixedly connected to the side wall of the rotating shaft 202d, and a sliding groove 204c is provided on the inner wall of the outer shell 101, and a sliding tooth plate 204d is slidably connected in the sliding groove 204c, and the sliding tooth plate 204d is meshed with the driving gear 204a and the transmission gear 204b.

[0033] Among them, the air inlet groove 103 is arranged on both sides of the shell 101, and the air in the electrical cabinet can be sucked in outside the air inlet of the fan to increase the exhaust volume of the shell 101. The temperature sensor 201a is arranged at the air inlet of the fan, and it controls the movement of the moving frame 201d by the electric slide rail 201c through the controller. When in use, the temperature sensor set according to the temperature range required for the use of the inverter in the electrical cabinet can control the movement of the electric slide rail 201c. When the rotating rod 203b is in use, the traction tooth plate 202a is a light plate structure on the side away from the electric slide rail 201c, and this section runs through the sliding connection guide groove 202c, wherein the two sliding tooth plates 204d located in the sliding groove 204c are centrally symmetrically arranged, and their engagement with the driving gear 204a can realize the synchronous and unidirectional rotation of multiple transmission gears 204b, that is, to achieve the synchronous effect of rotating and opening the drive of multiple grids 202e.

[0034] When in use, the temperature of the air sucked into the electrical cabinet by the fan is first measured by the temperature sensor. When the temperature is higher than the threshold value set by the temperature sensor, the mobile frame 201d on the electric slide rail 201c is controlled by the controller thereon to move. At this time, the mobile frame 201d drives the rotating rod 203b on the rotating base 203a thereon to move. At this time, the connecting shaft 203d on the rotating rod 203b contacts the inner wall of the fitting groove 203c and pushes the traction tooth plate 202a to slide in the guide groove 202c. When the traction tooth plate 202a is meshed with the driving gear 202b, the driving gear 202b drives the gear located in the middle position to move. The rotating shaft 202d is rotated, and the driving gear 204a rotates at this time, which meshes with the sliding tooth plates 204d on both sides, drives the sliding tooth plates 204d to slide in the sliding groove 204c, and meshes with multiple transmission gears 204b, and then drives the rotation of multiple transmission gears 204b, that is, the rotation drive of multiple rotating shafts 202d is realized, and the simultaneous rotation of multiple rotating shafts 202d in the same direction can drive the rotation and opening of the grid 202e thereon, and by increasing the rotation angle of the grid 202e, the air outlet of the shell 101 can be adjusted, and the exhaust efficiency and exhaust volume of the electrical cabinet are improved by adjusting the air outlet of the shell 101.

[0035] In summary, by controlling the opening and closing of the grille 202e through the temperature sensor, the exhaust volume of the housing 101 can be controlled. By increasing the size of the exhaust port and combining the negative pressure of the air inlet slot 103 to inhale the air inside the electrical cabinet, the exhaust volume and heat dissipation efficiency inside the electrical cabinet can be increased.

[0036] Example 2

[0037] Reference Figure 6, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a shift assembly 206 of the inverter electrical cabinet cooling device, which solves the problem of automatically adjusting and controlling the fan gear when the internal temperature of the electrical cabinet rises, increases the rotation speed of the fan, further increases the exhaust volume and improves the heat dissipation efficiency. It includes an adjustment assembly 205 including an adjustment box 205a fixedly connected to one side of the shell 101, an adjustment slot 205b is provided in the adjustment box 205a, a side of the traction tooth plate 202a close to the adjustment box 205a is fixedly connected to a limit block 205c, the limit block 205c is slidably connected in the adjustment slot 205b, a telescopic rod 205d is fixedly connected to one side of the limit block 205c, a push rod 205f is fixedly connected to the side wall of the telescopic rod 205d, and an inner wall of the adjustment slot 205b is provided with a push slot 205e. 5f extends into the propulsion slot 205e, a driving plate 205g is slidably connected in the adjusting slot 205b, the shift assembly 206 includes a pressure regulating disk 206a arranged in the adjusting slot 205b, an adjusting shaft 206b is provided on one side of the pressure regulating disk 206a, an adjusting gear 206c is fixedly connected to the side wall of the adjusting shaft 206b, an adjusting tooth plate 206d is fixedly connected to one side of the driving plate 205g, and the adjusting tooth plate 206d cooperates with the adjusting gear 206c, the supporting assembly 207 includes a supporting base 207a fixedly connected to the adjusting slot 205b, a sliding rod 207b is slidably connected in the supporting base 207a, one end of the sliding rod 207b is fixedly connected to the driving plate 205g, a supporting spring 207d is provided on the side wall of the driving plate 205g, a supporting slot 207c is provided on the inner wall of the adjusting slot 205b, and the driving plate 205g is slidably connected in the supporting slot 207c.

[0038] Specifically, the propulsion groove 205e is a structure in which three-stage grooves are connected, and a horizontal platform structure is arranged between the two inclined grooves. The inclined groove structure can be used to propel the driving plate 205g in the process of moving up and down, and the platform groove can stabilize the current gear position and provide a stable open state for the current gear position, thereby avoiding problems such as the voltage regulating disk 206a being broken due to rapid adjustment of the gear position, which affects the exhaust process of the fan. The end of the propulsion rod 205f located in the propulsion groove 205e is rotatably connected to a roller, and the rolling connection between the roller and the propulsion groove 205e can improve the continuity of the gear shifting process, thereby avoiding the problem of gear shifting jamming due to large resistance. The two ends of the support spring 207d are respectively fixedly connected between the driving plate 205g and the support base 207a, and are sleeved on the side wall of the sliding rod 207b.

[0039] When in use, the traction tooth plate 202a drives the limit block 205c to slide in the adjustment slot 205b during the process of being pushed by the rotating plate. At this time, the roller at the end of the pushing rod 205f rolls in the pushing slot 205e. When the continuous movement process is in the inclined position of the pushing slot, the pushing rod 205f drives the telescopic rod 205d to push the driving plate 205g downward. During this process, the driving plate 205g drives the adjusting tooth plate 206d to engage with the adjusting gear 206c, and drives the rotation of the adjusting shaft 206b. The rotation of the adjusting shaft 206b drives the rotation of the pressure regulating disk 206a. The rotation of the pressure regulating disk 206a can realize The gear position (i.e., voltage) of the fan is adjusted. Increasing the gear position of the fan can increase its speed. By changing the speed, the air circulation in the electrical cabinet is increased, thereby achieving the effect of promoting the rapid discharge of heat inside the electrical cabinet along with the air. During this process, the driving plate 205g slides in the supporting groove 207c. To ensure the stability of the driving plate 205g during the up and down movement, the driving plate 205g drives the sliding rod 207b to slide in the supporting base 207a and compresses the supporting spring 207d. However, when the traction tooth plate 202a moves in the reverse direction, the supporting spring 207d can provide a reverse thrust for the resetting process of the driving plate 205g.

[0040] In summary, the movement of the traction tooth plate 202a drives the grid 202e to adjust the air volume, and the driving plate 205g drives the rotation of the pressure regulating disk 206a to adjust the gear of the fan. By adjusting the gear, the rotation speed of the fan is increased, and the air suction effect of the fan is further improved, thereby achieving the effect of improving the heat dissipation efficiency of the inverter in the electrical cabinet.

[0041] Example 3

[0042] Reference Figure 7~Figure 8, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an expansion component 300 of the converter electrical cabinet cooling device, which solves the problem that the cabinet increases the effect of increasing the air intake from the outside during the use of the converter, increases the air flow in the electrical cabinet, and thus increases the heat dissipation efficiency of the converter. It includes a fixing component 301 including a fixing plate 301a fixedly connected to one side of the mounting plate 104, and a matching groove 301c is penetrated on one side of the fixing plate 301a. The connecting component 302 includes a sliding frame 302a fixedly connected to one side of the fixing plate 301a, and a connecting groove 302c is opened on one side of the sliding frame 302a. A guide groove 302c is opened on one side of the sliding frame 302a. 02d, the guide groove 302d runs through the fixed plate 301a, and the connecting groove 302c is slidably connected to the push bar 302b, one end of the push bar 302b is fixedly connected to the push tooth plate 302e, the push bar 302b is rotatably connected to the connecting shaft 203d, and the connecting shaft 203d is rollingly connected in the guide groove 302d, a ventilation plate 302j is provided on one side of the outer shell 101, and an expansion tooth plate 302i is fixedly connected to one side of the ventilation plate 302j, and an expansion gear 302h is provided on one side of the expansion tooth plate 302i, and the gear of the expansion gear 302h runs through a push shaft 302f, and a push gear 302g is fixedly connected to the side wall of the push shaft 302f, and the push gear 302g is meshed with the push tooth plate 302e.

[0043] Specifically, after the connecting shaft 203d is separated from the fitting groove 203c on the traction tooth plate 202a (the structure of the fitting groove 203c is as shown in FIG. Figure 3 As shown, an opening is set at the top to facilitate the disengagement of the connecting shaft 203d from the tooth plate) and the contact with the guide groove 302d, and drive the push bar 302b to move in the sliding frame 302a, wherein the push bar 302b is made of rubber and can bend in the sliding frame 302a, and the push tooth plate 302e is made of hard material, wherein the push shaft 302f is rotatably connected in the electrical cabinet, and the ventilation plate 302j is located at the top of the electrical cabinet and close to the side of the cabinet door. When it is opened, the air inhaled from the outside can pass through the inverter, thereby achieving the effect of carrying the heat from the inverter, and at the same time increasing the overall air intake of the electrical cabinet, thereby achieving the effect of promoting heat dissipation in the electrical cabinet.

[0044] When in use, the connecting shaft 203d contacts the guide groove 302d after being disengaged from the fitting groove 203c on the traction tooth plate 202a. At this time, the rotating plate can be rotated, tilted and moved through the inclined structure of the guide groove 302d and the rotating connection between the rotating plate and the rotating base 203a, thereby driving the propulsion bar 302b to move in the sliding frame 302a and pushing the propulsion tooth plate 302e to move in the sliding frame 302a. At this time, the propulsion tooth plate 302e is meshed with the propulsion gear 302g. The combination can drive the propulsion shaft 302f to rotate. At this time, the expansion gear 302h on the propulsion shaft 302f rotates and meshes with the expansion tooth plate 302i, driving the movement of the expansion tooth plate 302i, that is, driving the movement of the ventilation plate 302j on the expansion tooth plate 302i. At this time, the ventilation plate 302j moves on the top of the electrical cabinet, and the air inlet is opened on the top of the electrical cabinet to increase the overall air intake of the electrical cabinet. At the same time, the air entering through the air inlet passes through the inverter, can carry the heat generated around it, and is discharged through the fan, thereby improving the overall heat dissipation and cooling efficiency of the electrical cabinet.

[0045] In summary, by further moving the electric slide rail 201c and cooperating with the connecting component 302 to push the ventilation plate 302j to open, the air intake of the electrical cabinet can be increased while the heat generated around the inverter can be directly carried away and released, thereby accelerating the heat dissipation efficiency of the inverter and achieving the effect of improving the overall heat dissipation efficiency of the electrical cabinet.
