[0057] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figures 1 to 13 As shown:

[0059] A mobile vibration-damping and heat-dissipating electric power distribution cabinet comprises a dust-proof and heat-dissipating cabinet installed on a shock-absorbing cart 1. The dust-proof and heat-dissipating distribution cabinet comprises a distribution cabinet body 2 installed on the shock-absorbing cart 1. The side of the distribution cabinet body 2 is provided with a plurality of air outlets and air inlets. The distribution cabinet body 2 is also provided with a sealing door. An automatic dust removal device 4 is installed at the air inlet of the distribution cabinet body 2. A first dust-proof net 3 is installed on the automatic dust removal device 4. An air suction device 5 for sucking air is also installed on the automatic dust removal device 4. A power conduction device 6 for conducting kinetic energy to the automatic dust removal device 4 is installed on the air suction device 5. A guiding air supply mechanism 7 for guiding airflow is also installed on the air suction device 5. A pull-out dust removal mechanism 9 is installed on the air outlet of the distribution cabinet body 2. A second dust-proof net 8 is installed on the pull-out dust removal mechanism 9.

[0060] The staff uses the shock-absorbing cart 1 to smoothly push the dust-proof heat dissipation cabinet to the place where it is needed. The staff installs the power control equipment inside the distribution cabinet 2 of the dust-proof heat dissipation cabinet. After the power controller is installed, the staff closes the sealed door. The power controller will generate a large amount of heat energy when it is on the working seat. The suction device 5 generates a suction force to draw air in from the air inlet of the distribution cabinet 2. When the air enters, it will pass through the first dust-proof net 3 installed on the automatic dust removal device 4. The first dust-proof net 3 will remove dust and purify the incoming air, effectively preventing the air in the outer wall environment from entering and causing controller failure. After the suction device 5 draws in the outside air, it transports the inhaled air to the guiding air supply mechanism 7. The guiding air supply mechanism 7 accurately guides the sucked air to blow toward the power controller. Effectively ensure the heat dissipation effect of the power controller, the hot air inside the distribution cabinet 2 will flow out through the air outlet of the distribution cabinet 2, and the second dustproof net 8 on the pulling and pulling dust removal mechanism 9 can effectively prevent dust from entering from the air outlet of the distribution cabinet 2 and causing damage. When the air inlet of the distribution cabinet 2 sucks air, a large amount of dust will adhere to the first dustproof net 3, causing blockage and affecting the suction efficiency. When a large amount of dust adheres to the first dustproof net 3, the power transmission device 6 guides the rotational kinetic energy of the suction device 5 to the automatic dust removal device 4, so that the automatic dust removal device 4 starts and automatically removes the first dustproof net 3 to ensure that the first dustproof net 3 maintains good air circulation. At the same time, the staff can quickly clean the second dustproof net 8 by pulling and pulling the dust removal mechanism 9, which can effectively clean the second dustproof net 8.

[0061] like Figure 3 and Figure 4 As shown:

[0062] The automatic dust removal device 4 includes an installation frame 41 installed at the air inlet, and a first limiting installation groove 411 for installing the first dustproof net 3 is provided inside the installation frame 41. A limiting clamping groove 412 is provided at one end of the installation frame 41 away from the first limiting installation groove 411, and a pressure cleaning frame 42 for cleaning the first dustproof net 3 is also installed at the first limiting installation groove 411.

[0063] After the staff puts the first dustproof net 3 into the first limiting mounting groove 411 of the mounting frame 41, the staff presses and fixes the first dustproof net 3 by pressing and fixing the first dustproof net 3. After the first dustproof net 3 is pressed and fixed, the suction device 5 generates a suction force to draw air into the air inlet of the distribution cabinet 2. The air passes through the first dustproof net 3 when entering. The first dustproof net 3 removes dust and purifies the incoming air, effectively preventing the air in the outer wall environment from entering and causing controller failure. When filtering, the first dustproof net 3 will cause a large amount of dust to adhere to the first dustproof net 3 and cause blockage. The power transmission device 6 guides the rotational kinetic energy of the suction device 5 to the pressing and cleaning frame 42, so that the pressing and cleaning frame 42 rotates. When the pressing and cleaning frame 42 rotates, it rubs and cleans with the first dustproof net 3, effectively ensuring the fluidity of the first dustproof net 3.

[0064] like Figure 4 and Figure 5 As shown:

[0065] The pressure cleaning frame 42 includes a first pressure frame 421 installed inside the first limiting installation groove 411, a rotating track 4211 is provided inside the first pressure frame 421, a rotating frame 422 is installed inside the rotating track 4211, a rotating frame 422 is provided at the axial position of the rotating frame 422, an anti-slip surface 4231 is provided at one end of the rotating frame 422 away from the rotating frame 422, and a plurality of cleaning brush strips 424 are installed on the rotating frame 422.

[0066] When the staff puts the first dustproof net 3 into the first limiting mounting groove 411 of the mounting frame 41, the first pressing frame 421 is used to press and fix the first dustproof net 3 in the first limiting mounting groove 411, so that the first dustproof net 3 is positioned and fixed. When filtering the air, the first dustproof net 3 will cause dust to adhere to the first dustproof net 3 and cause blockage. The power transmission device 6 will periodically conflict with the rotating transmission shaft 423 and drive the rotating transmission shaft 423 to rotate. When the rotating transmission shaft 423 rotates, it drives the rotating frame 422 to rotate. When the rotating frame 422 rotates, it drives the cleaning brush strip 424 to rotate synchronously. When the cleaning brush strip 424 rotates, it cleans the surface of the first dustproof net 3, and effectively and automatically cleans the first dustproof net 3, saving manpower.

[0067] like Figure 3 and Figure 6 As shown:

[0068] The suction device 5 includes a docking guide bucket 51 installed on the mounting frame 41, a positioning clamping mechanism 52 is provided at the docking position between the docking guide bucket 51 and the mounting frame 41, a plurality of first guide grooves 511 are provided at the docking end of the docking guide bucket 51, a plurality of second guide grooves 512 are provided at the side of the docking guide bucket 51, and a suction fan 53 is installed inside the docking guide bucket 51.

[0069] The docking guide bucket 51 is fixed to the limiting clamping groove 412 of the mounting frame 41 by a positioning clamping mechanism 52. When it is necessary to suck external air, the suction fan 53 rotates inside the docking guide bucket 51 to make the external air flow to the inside of the docking guide bucket 51. The docking guide bucket 51 guides the incoming air to the guiding air supply mechanism 7. The guiding air supply mechanism 7 guides the incoming airflow to blow onto the power control equipment, so that the power control equipment can be cooled down quickly.

[0070] like Figure 6 and Figure 7 As shown:

[0071] The positioning clamping mechanism 52 includes several sliding clamping blocks 521 installed inside the first guide groove 511, the sliding clamping block 521 is provided with a connecting rod, and the connecting rod is provided with a pressing clamping block. The positioning clamping mechanism 52 also includes a driving ring 522 installed on the docking guide bucket 51, the driving ring 522 is provided with several driving inclined grooves 5221, the driving inclined grooves 5221 are slidably connected with the connecting rod of the sliding clamping block 521, and the side of the driving ring 522 is also provided with several docking guide blocks, and the driving ring 522 is also provided with a driving handle 523.

[0072] When it is necessary to clamp and fix the docking guide bucket 51 with the mounting frame 41, the worker inserts the docking guide block on the driving ring 522 into the limiting clamping groove 412 of the mounting frame 41. The docking guide block on the driving ring 522 can effectively ensure the accuracy of the docking. After the driving ring 522 and the limiting clamping docking of the mounting frame 41 are in conflict, the staff drives the driving ring 522 to rotate by driving the handle 523. When the driving ring 522 rotates, it drives the sliding clamping block 521 to expand and slide along the first guide groove 511 of the docking guide bucket 51 through the driving inclined groove 5221. When the sliding clamping block 521 expands and moves, it will be clamped in the first guide groove 511 to position and fix the docking guide bucket 51. At the same time, after the driving ring 522 expands and fixes the sliding clamping block 521, the staff then fixes the driving ring 522 to the side of the docking guide bucket 51 by bolts. The clamping fixation can facilitate quick disassembly, effectively improving the convenience of maintenance.

[0073] like Figure 7 and Figure 8 As shown:

[0074] The power transmission device 6 includes a limit mounting seat 61 installed at the axial position of the suction fan 53, a limit guide column 62 is provided on the limit mounting seat 61, a plurality of first limit slide grooves 621 are provided on the outer side of the limit guide column 62, a transmission pressure frame 63 is installed inside the first limit slide groove 621, a limit protrusion is provided on the transmission pressure frame 63, an elastic pressure block 631 is provided at the pressure end of the transmission pressure frame 63, and the power transmission device 6 also includes a limit pushing device 64 for driving the transmission pressure frame 63 to move.

[0075] After the docking guide bucket 51 is snap-fitted and fixed to the mounting frame 41, external air is sucked in by the suction fan 53. When the air enters, it passes through the first dustproof net 3. The first dustproof net 3 will remove dust and purify the incoming air, effectively preventing the air in the outer wall environment from entering and causing controller failure. When filtering, the first dustproof net 3 will cause a large amount of dust to adhere to the first dustproof net 3 and cause blockage. When the suction fan 53 rotates, it will drive the mounting seat to rotate. When the mounting seat rotates, it drives the limiting guide column 62 to rotate synchronously. When the limiting guide column 62 rotates, it drives the transmission pressing frame 63 to rotate synchronously. If the first dustproof net 3 needs to be cleaned regularly, the limiting pushing device 64 pushes the rotating transmission pressing frame 63 to extend toward the rotating transmission shaft 423 of the pressing and cleaning frame 42, so that the elastic pressing block 631 of the transmission pressing frame 63 conflicts with the rotating transmission shaft 423 of the pressing and cleaning frame 42, and transmits the rotational kinetic energy to the pressing and cleaning frame 42. By effectively guiding the kinetic energy of the suction fan 53, energy consumption is saved.

[0076] like Figures 7 to 10 As shown:

[0077] The limiting pushing device 64 includes a pushing frame 641 slidably installed inside the second guide groove 512, a limiting mounting hole is provided at the axial position of the pushing frame 641, and a second limiting slide groove 6411 is provided on the inner wall of the limiting mounting hole. The limiting pushing device 64 also includes a linear driver 642 installed on the side of the docking guide bucket 51, and the extending end of the linear driver 642 is connected to the pushing frame 641.

[0078] The linear drive 642 is preferably an electric push rod. When it is necessary to push the rotating transmission pressure frame 63 to collide with the rotating transmission shaft 423 of the pressure cleaning frame 42 at a timed interval, the control module controls the electric push rod to push the pushing frame 641 at a timed interval to drive the transmission pressure frame 63 to extend toward the rotating transmission shaft 423 of the pressure cleaning frame 42. Effective timed cleaning ensures the fluidity of the first dustproof net 3.

[0079] like Figures 1 to 3 As shown:

[0080] The air supply guiding mechanism 7 includes a connecting pipe 71 installed in connection with the docking guide bucket 51, the connecting pipe 71 is connected to a guide rail 72, the guide rail 72 is installed inside the power distribution cabinet 2, a plurality of air outlets 73 are installed on the guide rail 72, and an air guide inclined plate 721 is provided inside the guide rail 72.

[0081] After the air suction device 5 sucks in the external air, it transports the sucked air to the connecting pipe 71, and the connecting pipe 71 guides the air to the inside of the guide rail 72. The wind guide inclined plate 721 inside the guide rail 72 is used to guide the incoming air to the corresponding air outlet 73. The air outlet 73 blows the air to the power controller to quickly cool the power controller.

[0082] like Figure 1 and Fig.11 As shown:

[0083] The pull-out dust removal mechanism 9 comprises a ventilation slide rail 91 installed on the air outlet, the inner wall of the ventilation slide rail 91 is covered with cleaning brushes 911 , and an elastic pull-out rail 92 is installed on the ventilation slide rail 91 .

[0084] The elastic pull-out rail 92 inside the ventilation slide rail 91 is used to install the second dustproof net 8. The second dustproof net 8 can effectively prevent dust from entering the interior from the air outlet of the distribution cabinet 2. Generally, only a small amount of dust will adhere to the second dustproof net 8. When the staff inspects, they can pull the elastic pull-out rail 92 by hand. When the elastic pull-out rail 92 is pulled, it drives the second dustproof net 8 to rub against the cleaning brush 911 covered on the inner wall of the ventilation slide rail 91. When the second dustproof net 8 rubs against the cleaning brush 911, the dust attached to the second dustproof net 8 will be cleaned, so that the second dustproof net 8 remains circulated.

[0085] like Figures 11 to 13 As shown:

[0086] The elastic pull-out rail 92 includes a pull-out mounting rail 921 installed inside the ventilation slide rail 91, a second mounting slot 9211 is provided inside the pull-out mounting rail 921, a pull-out handle 9212 is provided on the side of the pull-out mounting rail 921, a fixed pressing frame 922 for pressing the second dustproof net 8 is installed inside the second mounting slot 9211, and the elastic pull-out rail 92 also includes a limiting mounting rail 923 installed on the side of the ventilation slide rail 91, a pull-out block 924 is provided inside the limiting mounting rail 923, a spring 926 is provided between the pull-out block 924 and the limiting mounting rail 923, and a pull rope 925 is also provided on the pull block 924, and the end of the pull rope 925 away from the pull block 924 is connected to the ventilation slide rail 91.

[0087] When the staff needs to install the second dust-proof net 8, the staff puts the second dust-proof net 8 into the second installation slot 9211 of the pull-out mounting rail 921, and then presses the second dust-proof net 8 into position through the fixed pressing frame 922, so that the second dust-proof net 8 is installed on the pull-out mounting rail 921. Every time the staff pulls and cleans the second dust-proof net 8, the staff pulls the pull-out handle 9212, and the pull-out handle 9212 drives the pull-out mounting rail 921 to move. When the pull-out mounting rail 921 moves, it drives the second dust-proof net 8 to rub against the cleaning brush 911 covered with the inner wall of the ventilation slide rail 91. When the second dust-proof net 8 rubs against the cleaning brush 911, The dust attached to the second dustproof net 8 is cleaned, and the pull rope 925 moves at the same time when the pull-out mounting rail 921 is pulled. When the pull rope 925 moves, it drives the pull-out block 924 inside the limit mounting rail 923 to move, and the pull-out block 924 will definitely squeeze the spring 926. When the staff releases the pull handle 9212, the spring 926 drives the pull-out block 924 to reset. When the pull block 924 is reset, the pull-out mounting rail 921 is reset through the pull rope 925, so that the pull-out mounting rail 921 is retracted and moved to the inside of the ventilation slide rail 91, which is convenient for resetting and cleaning the second dustproof net 8, and effectively improves the convenience of the second dustproof net 8.

[0088] Specific working principle:

[0089] The staff uses the shock-absorbing cart 1 to smoothly push the dust-proof heat dissipation cabinet to the place where it is needed. The staff installs the power control equipment inside the distribution cabinet 2 of the dust-proof heat dissipation cabinet. After the power controller is installed, the staff closes the sealed door. The power controller will generate a large amount of heat energy when it is on the working seat. The suction device 5 generates a suction force to draw air in from the air inlet of the distribution cabinet 2. When the air enters, it will pass through the first dust-proof net 3 installed on the automatic dust removal device 4. The first dust-proof net 3 will remove dust and purify the incoming air, effectively preventing the air in the outer wall environment from entering and causing controller failure. After the suction device 5 draws in the outside air, it transports the inhaled air to the guiding air supply mechanism 7. The guiding air supply mechanism 7 accurately guides the sucked air to blow toward the power controller, which can effectively ensure the heat dissipation effect of the power controller. The hot air inside the distribution cabinet 2 will flow out through the air outlet of the distribution cabinet 2. The second dustproof net 8 on the pulling and pulling dust removal mechanism 9 can effectively prevent dust from entering from the air outlet of the distribution cabinet 2 and causing damage. When the air inlet of the distribution cabinet 2 sucks air, a large amount of dust will adhere to the first dustproof net 3, causing blockage and affecting the suction efficiency. When a large amount of dust adheres to the first dustproof net 3, the power transmission device 6 guides the rotational kinetic energy of the suction device 5 to the automatic dust removal device 4, so that the automatic dust removal device 4 starts and automatically removes the first dustproof net 3 to ensure that the first dustproof net 3 maintains good air circulation. The staff can also quickly clean the second dustproof net 8 by pulling and pulling the dust removal mechanism 9, which can effectively clean the second dustproof net 8. The present application can effectively prevent dust from entering the equipment and causing damage, while maintaining the heat dissipation effect.

[0090] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
