It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In one embodiment, see Figure 1 , Figure 2 and Figure 5 An assembled heat dissipation type high and low voltage complete switch cabinet comprises a cabinet 1, and air inlets 6 are arranged on two relatively distributed side walls of the cabinet 1, and mesh plates 5 are installed at the air inlets 6, wherein the mesh plates 5 are detachably connected to the cabinet 1, and a fixing mechanism 4 is arranged outside the cabinet 1, and the fixing mechanism 4 is used to fix the mesh plates 5, and an air outlet 7 is arranged on the top of the cabinet 1, and a casing 8 is installed outside the air outlet 7, and the casing 8 is fixedly connected to the top of the cabinet 1, wherein an induced draft fan is installed inside the casing 8, and symmetrically distributed baffles 2 are arranged inside the cabinet 1, and the baffles 2 are slidably connected to the inner wall of the cabinet 1 and are connected to a lifting mechanism 3, and the lifting mechanism 3 is used to drive the baffle 2 to move up and down, thereby controlling the baffle 2 to block the air inlet 6.

[0022] In this embodiment, when the switch cabinet is in use, the induced draft fan (not shown in the figure) inside the casing 8 is started. Under the action of the induced draft fan, the external airflow enters the cabinet 1 through the air inlet 6. After entering the cabinet 1, the airflow moves upward, then enters the casing 8 through the air outlet 7, and is finally discharged from the top of the casing 8. The air inlet 6 is arranged on both sides of the cabinet 1, and the air outlet 7 is arranged on the top of the cabinet 1. After the airflow enters the cabinet 1, it moves upward, which can effectively increase the area of ​​the airflow flowing inside the cabinet 1, thereby improving the heat dissipation effect of the electrical components inside the cabinet 1. In addition, mesh panels 5 are installed at the air inlet 6. The setting of the mesh plate 5 can effectively prevent external dust from entering the cabinet 1 through the air inlet 6 and causing damage to the electrical components inside the cabinet 1, thereby improving the protection performance of the electrical components inside the cabinet 1, and the mesh plate 5 is detachably connected to the air inlet 6, which is convenient for the staff to install and remove the mesh plate 5. A baffle 2 is also provided inside the cabinet 1. When encountering bad weather, the baffle 2 is driven downward by the lifting mechanism 3, so that the baffle 2 blocks the air inlet 6, which can effectively prevent rainwater from entering the cabinet 1 through the air inlet 6 and causing damage to the solid internal electrical components, further improving the damage to the electrical components inside the cabinet 1.

[0023] See also Figure 3 The lifting mechanism 3 includes a top plate 33 arranged above the cabinet 1, a hydraulic rod 32 and symmetrically distributed sliding rods 310 are fixed to the bottom of the top plate 33, the sliding rod 310 and the hydraulic rod 32 both penetrate the top of the cabinet 1 and are slidably connected to the top of the cabinet 1, the bottom of the sliding rod 310 is fixedly connected to the top of the baffle 2, wherein a hydraulic cylinder 31 is installed on the top of the cabinet 1, and the output end of the hydraulic cylinder 31 is fixedly connected to the lower end of the hydraulic rod 32; When encountering bad weather, the hydraulic cylinder 31 is started, and the hydraulic cylinder 31 drives the top plate 33 to move downward through the hydraulic rod 32. The top plate 33 drives the baffle 2 to move downward through the sliding rod 310 until the baffle 2 completely blocks the air inlet 6. The air inlet 6 is sealed by the baffle 2, which can effectively prevent external rainwater from entering the cabinet 1 through the air inlet 6, thereby improving the protection performance of the cabinet 1.

[0024] See also Figure 2 The side walls of the top plate 33 are rotatably connected with connecting rods 311, and the other end of the connecting rod 311 is rotatably connected with a sealing plate 312, and the bottom of the sealing plate 312 is slidably connected to the top of the cabinet 1, wherein the sealing plate 312 passes through the side wall of the casing 8 and is slidably connected to the side wall of the casing 8; When sealing the air inlet 6, the hydraulic cylinder 31 drives the top plate 33 to move downward through the hydraulic rod 32. While the top plate 33 moves downward, the sealing plate 312 is driven to move horizontally through the connecting rod 311 until the two sealing plates 312 fit together. The sealing plate 312 can seal the air outlet 7, further improving the sealing performance of the cabinet 1, thereby preventing rainwater from entering the cabinet 1 through the air outlet 7.

[0025] See also Figure 3 and Figure 5 The baffle plate 2 is connected to a back-blowing assembly. When the baffle plate 2 blocks the air inlet 6, the back-blowing assembly is used to blow air to the mesh plate 5, thereby cleaning the outside of the mesh plate 5; When the air inlet 6 is sealed, the top plate 33 drives the baffle plate 2 to move downward through the sliding rod 310. The baffle plate 2 moves downward and drives the back-blowing component to operate. Air is blown toward the surface of the mesh plate 5 through the back-blowing component, so that dust or impurities on the outer surface of the mesh plate 5 are blown off, which has a self-cleaning effect on the mesh plate 5. It can effectively prevent the dust from blocking the mesh plate 5 and causing poor ventilation, and there is no need to manually clean the mesh plate 5, saving manpower.

[0026] See also Figure 3 , Figure 4 and Figure 5 The backflush assembly includes a plurality of air outlet holes 313 arranged at the lower end of the side wall of the baffle 2, the air outlet holes 313 are arranged toward the air inlet 6, and the air outlet holes 313 are connected to each other, wherein two of the air outlet holes 313 are connected to a hose 39, and the other end of the hose 39 is connected to an air intake component, and the air intake component is used to ventilate the inside of the hose 39; When the top plate 33 drives the baffle plate 2 to move downward through the slide rod 310, the air intake component ventilates the inside of the hose 39, and the gas enters the inside of the baffle plate 2 through the hose 39 and is finally discharged from the air outlet 313. The gas discharged through the air outlet 313 blows off the dust or impurities on the surface of the mesh plate 5, and then cleans the mesh plate 5, thereby avoiding the phenomenon of poor ventilation caused by dust blocking the mesh plate 5. When the baffle plate 2 moves downward, it also drives the air outlet 313 to move downward, so that the gas discharged from the air outlet 313 can comprehensively clean the mesh plate 5, effectively improving the cleaning effect of the mesh plate 5.

[0027] See also Figure 3 The air intake component includes a support rod 34 fixedly connected to the bottom of the top plate 33 and symmetrically distributed, a support plate 37 is fixed on the outer wall of the cabinet 1, and a symmetrically distributed air pressure cylinder 36 is fixed on the top of the support plate 37. The air pressure cylinder 36 is connected to an air outlet pipe 38, and the air outlet pipe 38 passes through the side wall of the cabinet 1 and is respectively connected to the two hoses 39. A piston 35 is slidably connected inside the air pressure cylinder 36, and the piston 35 is fixedly connected to the bottom of the support rod 34; When the top plate 33 moves downward, it also drives the support rod 34 to move downward. The support rod 34 drives the piston 35 to move inside the air cylinder 36. When the piston 35 moves inside the air cylinder 36, it squeezes the gas inside the air cylinder 36, so that the gas inside the air cylinder 36 enters the hose 39 through the outlet pipe 38. The gas enters the baffle 2 through the hose 39 and is finally discharged from the outlet hole 313, thereby cleaning the surface of the mesh plate 5.

[0028] See also Figure 5 The fixing mechanism 4 includes support steps 41 arranged on the top and bottom of the air inlet 6, and symmetrically distributed mounting plates 43 are fixed on both sides of the air inlet 6 and the outer wall of the cabinet 1. The mounting plates 43 are penetrated by pull rods 44, and the ends of the pull rods 44 close to the air inlet 6 are fixed with trapezoidal blocks 42, and the trapezoidal blocks 42 are connected to the mounting plates 43 through elastic components 45; When installing the mesh panel 5, align the mesh panel 5 with the air inlet 6 and press the mesh panel 5 downward. The mesh panel 5 squeezes the inclined surface of the trapezoidal block 42. When the mesh panel 5 enters the air inlet 6 and fits tightly with the supporting step 41, the outer surface of the mesh panel 5 is flush with the outer wall of the cabinet 1. At this time, the trapezoidal block 42 automatically resets under the action of the elastic component 45. The plane of the trapezoidal block 42 can exert a pressing effect on the mesh panel 5, thereby effectively improving the stability of the mesh panel 5 and facilitating the staff to quickly install the mesh panel 5. When the mesh panel 5 needs to be disassembled, the trapezoidal block 42 is pulled by the pull rod 44 so that the trapezoidal block 42 no longer presses the mesh panel 5. The elastic component 45 can be a spring.

[0029] Working principle: When the switch cabinet is in use, the induced draft fan inside the casing 8 is started. Under the action of the induced draft fan, the external airflow enters the cabinet 1 through the air inlet 6. After entering the cabinet 1, the airflow moves upward and is then discharged through the air outlet 7. While passing through the cabinet 1, the airflow will take away part of the heat inside the cabinet 1, thereby achieving a heat dissipation effect. In addition, mesh panels 5 are installed at the air inlet 6. The setting of the mesh panels 5 can effectively prevent external dust from entering the cabinet 1 through the air inlet 6 and causing damage to the electrical components inside the cabinet 1, thereby improving the protection performance of the electrical components inside the cabinet 1, and the mesh panels 5 and the air inlet 6 Removable connection. When the mesh panel 5 needs to be installed, align the mesh panel 5 with the air inlet 6 and press the mesh panel 5 downward. The mesh panel 5 squeezes the inclined surface of the trapezoidal block 42. When the mesh panel 5 enters the inside of the air inlet 6 and fits tightly with the supporting step 41, the outer surface of the mesh panel 5 is flush with the outer wall of the cabinet 1. At this time, the trapezoidal block 42 automatically resets under the action of the elastic component 45. The plane of the trapezoidal block 42 can play a pressing and holding role on the mesh panel 5, thereby effectively improving the stability of the mesh panel 5 and facilitating the rapid installation of the mesh panel 5 by the staff. A baffle 2 is also provided inside the cabinet 1. When encountering bad weather, the hydraulic cylinder 31 is connected through the hydraulic rod 3 2 drives the top plate 33 to move downward, and the top plate 33 drives the baffle plate 2 to move downward through the sliding rod 310 until the baffle plate 2 completely blocks the air inlet 6. The baffle plate 2 seals the air inlet 6, which can effectively prevent external rainwater from entering the cabinet body 1 through the air inlet 6, thereby improving the protection performance of the cabinet body 1. When the baffle plate 2 moves downward, it will also drive the sealing plate 312 to move horizontally through the connecting rod 311 until the two sealing plates 312 fit together, and the sealing plate 312 can play a sealing role on the air outlet 7, thereby further improving the sealing performance of the cabinet body 1, thereby preventing rainwater from entering the cabinet body 1 through the air outlet 7. At the same time, the top plate 33 will also drive the support rod 34 to move downward, and the support rod 34 will drive the piston 35 to move inside the air cylinder 36. The piston 35 squeezes the gas inside the air cylinder 36 while moving inside the air cylinder 36, so that the gas inside the air cylinder 36 enters the hose 39 through the air outlet pipe 38. The gas enters the baffle 2 through the hose 39 and is finally discharged from the air outlet 313, thereby blowing off dust or impurities on the surface of the mesh plate 5, which has a self-cleaning effect on the mesh plate 5, and can effectively avoid the phenomenon of poor ventilation caused by dust blocking the mesh plate 5, and there is no need to manually clean the mesh plate 5, saving manpower.
