[0025] See also Figure 1-5 The utility model provides a technical solution: a heat dissipation and dustproof elevator control cabinet, including an elevator control cabinet 1, the main body of the elevator control cabinet 1 is iron and is sprayed with anti-rust paint inside and outside, as shown in the attached Figure 1As shown, the front of the elevator control cabinet 1 is provided with a closed cabinet door 2, which is hinged to the opening side of the elevator control cabinet 1 and can be closed by flipping a switch. Through the overall sealing of the elevator control cabinet 1, a safety lock seat 12 is provided on the front side of the closed cabinet door 2, and a lock cylinder is provided in the middle of the safety lock seat 12, which needs to be opened by a specific key, thereby improving the safety of the elevator control cabinet 1. Wire through holes 11 are evenly opened on the bottom side of the elevator control cabinet 1 for inserting and installing control wiring. In order to facilitate the installation of the elevator control cabinet 1, a bolt mounting hole 13 is provided at the rear of the elevator control cabinet 1. The elevator control cabinet 1 adopts a wall-mounted installation method, which is far away from the ground and has a certain waterproof safety.

[0026] In order to facilitate the heat dissipation of the components in the elevator control cabinet 1, air inlets are provided on both sides of the elevator control cabinet 1. The air inlets are symmetrically fixed on both sides of the elevator control cabinet 1. In order to reduce the entry of dust, as shown in the attached Figure 2 As shown, an arc-shaped air guide plate 3 is provided on the opening side of the air inlet. The arc-shaped air guide plate 3 is evenly fixed on the opening side of the air inlet. The arc-shaped air guide plate 3 adopts an arc-shaped structure. The opening of the air inlet is converted to the lower part by guiding the air flow. When not in working state, the naturally falling dust from the outside can be effectively blocked and shielded, so that the amount of dust entering is greatly reduced.

[0027] In order to realize air circulation and heat dissipation and improve the heat dissipation capacity of the elevator control cabinet 1, a bottom air outlet 9 is provided at the bottom of the elevator control cabinet 1. Figure 2 As shown, the bottom air outlet 9 is opened through the bottom side of the elevator control cabinet 1 to reduce the entry of dust. While ensuring the heat dissipation of the elevator control cabinet 1, the arc cover-shaped air guide plate 3 can be used to further reduce the amount of dust entering. In order to improve the active heat dissipation capacity of the elevator control cabinet 1, a cooling fan 10 is arranged on the air inlet side of the bottom air outlet 9. The cooling fan 10 is fixed to the inner lower part of the elevator control cabinet 1 by bolts. The cooling fan 10 is attached to the air inlet side of the bottom air outlet 9. When necessary, active heat dissipation of the elevator control cabinet 1 can be achieved through active exhaust to ensure the normal operation of the components in the elevator control cabinet 1.

[0028] In order to further improve the dustproof ability of the elevator control cabinet 1, a dustproof mechanism 4 is arranged on the lower opening side of the arc cover-shaped air guide plate 3. The dustproof mechanism 4 includes a mounting frame plate 5, an adsorption magnetic block 6, a dustproof net 7 and a connecting convex seat 8. The main body of the mounting frame plate 5 is made of fireproof plastic material. The mounting frame plate 5 is provided with multiple mounting frames, which are installed by independent interlocking, such as the attached Figure 4 As shown, the connecting protrusion 8 is evenly fixed to the front of the mounting frame 5, the dust screen 7 is a leak-hole type dust screen cover, and the dust screen 7 is fixed to the middle of the connecting protrusion 8. In order to facilitate the fitting installation of the dust screen 7, as shown in the attached Figure 3 As shown, a connecting slot is provided at the lower part of the arc-shaped air guide plate 3, and the connecting slot is adapted to the connecting protrusion 8. The connecting protrusion 8 is inserted into the inner side of the connecting slot from the inside of the elevator control cabinet 1, and the upper edge side of the connecting protrusion 8 is laterally fitted with the lower opening of the arc-shaped air guide plate 3, so that the dustproof net 7 is installed on the lower opening side of the arc-shaped air guide plate 3. The dust on the air inlet side can be further blocked and filtered by the setting of the dustproof net 7.

[0029] In order to improve the convenience of disassembly and assembly of the dustproof mechanism 4, the adsorption magnetic blocks 6 are symmetrically and evenly arranged on both sides of the installation frame plate 5. The adsorption magnetic blocks 6 are circular neodymium magnets. The adsorption magnetic blocks 6 are fixedly embedded in the side of the installation frame plate 5. The adsorption magnetic blocks 6 are adsorbed on the inner wall of the elevator control cabinet 1. The dustproof net 7 can be removably installed on the lower opening side of the arc cover-shaped air guide plate 3 through the adsorption magnetic blocks 6 and the connecting protrusions 8. It is easy to disassemble and assemble and has good disassembly and assembly convenience. The adsorption magnetic blocks 6 can realize magnetic adsorption and fixation of the installation frame plate 5, which further increases the installation stability of the dustproof net 7.

[0030] Working principle or structural principle, during installation, the elevator control cabinet 1 is installed on the upper part of the wall through the bolt mounting holes 13 on the back of the elevator control cabinet 1 and the bolt structure, and then the connecting protrusion 8 on the front of the installation frame plate 5 is aligned with the connecting slot under the arc cover-shaped air guide plate 3, and the dustproof net 7 is installed on the lower air inlet side of the arc cover-shaped air guide plate 3 by interlocking and plugging. After being interlocked in place, the adsorption magnetic block 6 on the side of the installation frame plate 5 is in contact with the inner wall of the elevator control cabinet 1, and is firmly adsorbed on the inner wall side of the elevator control cabinet 1 by magnetic force, and the installation limit of the dustproof mechanism 4 is completed by the interlocking of the connecting protrusion 8 and the connecting slot. Similarly, the removal operation of the dustproof mechanism 4 can be completed by pushing the connecting protrusion 8 from the outside and pulling the installation frame plate 5, and the installation of the remaining dustproof nets 7 is completed in sequence, and then the electrical components are installed inside the elevator control cabinet 1, and then the external control wiring is connected to complete the installation operation of the elevator control cabinet 1;

[0031] When natural heat dissipation is performed, the cooling fan 10 at the bottom of the elevator control cabinet 1 is in a non-working state, and external dust falls naturally. The dust at the air inlet is blocked and isolated by the arc cover-shaped air guide plate 3 and the dustproof net 7. At the same time, due to the downward placement of the bottom air outlet 9, the dust on the air outlet side is also difficult to enter the interior of the elevator control cabinet 1. When active heat dissipation is performed, the cooling fan 10 at the bottom of the elevator control cabinet 1 is in a working state. The cooling fan 10 draws air out of the elevator control cabinet 1. Affected by the exhaust effect, the dust on the air outlet side cannot enter the interior of the elevator control cabinet 1. The external air enters the elevator control cabinet 1 through the air inlet. The obstruction of the arc cover-shaped air guide plate 3 can reduce the amount of dust entering. At the same time, the dustproof net 7 can filter and block the entering dust, which can effectively prevent the entry of dust.

[0032] In summary, the control cabinet adopts an arc cover guide type entry structure, and arc cover-shaped air guide plates 3 are arranged at the air inlets on both sides of the elevator control cabinet 1. The arc cover-shaped air guide plates 3 adopt an arc-shaped structure, and the opening of the air inlet is converted to the lower part by guiding the air. When not in working state, the dust naturally falling from the outside can be effectively blocked and shielded, so that the amount of dust entering is greatly reduced, and the bottom air outlet 9 is arranged at the bottom of the elevator control cabinet 1. While ensuring the heat dissipation of the elevator control cabinet 1, the arc cover-shaped air guide plates 3 can be used to further reduce the amount of dust entering, and a dustproof net 7 is arranged on the lower air inlet side of the arc cover-shaped air guide plate 3. The dustproof net 7 is installed by connecting the protruding seat 8 and inserting it in combination with the adsorption and fixation of the adsorption magnetic block 6. It is easy to disassemble and has good disassembly and assembly convenience. The dust on the air inlet side can be further blocked and filtered through the setting of the dustproof net 7, which further improves the dustproof characteristics of the elevator control cabinet 1.
