Technical Field

[0001] The present invention belongs to the technical field of control cabinets, and particularly relates to an industrial control cabinet with an adaptive external air duct. Background Art

[0002] An industrial control cabinet is a device specifically designed for industrial automation control systems. It is a computing device used to monitor input signals, execute preset tasks, and control output signals, thereby realizing the automatic control of industrial processes. In the existing control cabinets, during use, a large amount of heat is easily generated by the electronic components and equipment inside the control cabinet. Therefore, it is necessary to ventilate and dissipate heat from the control cabinet to ensure the normal operation of the internal electrical components.

[0003] Currently, general control cabinets usually dissipate heat through air cooling. Air cooling can effectively cool the cabinet at normal temperatures. However, when encountering high-temperature weather, since the external temperature is relatively high, the air blown in by the fan becomes hot air, thus unable to effectively cool the control cabinet. Some control cabinets adopt water cooling to dissipate heat, and continuously cool by pumping cooling water through a water pump. Although the heat dissipation effect is improved, the energy consumption of the water pump during long-term operation is relatively large. Summary of the Invention

A temperature sensor 12 is installed inside the cabinet 1, and the temperature sensor 12 is connected to the on / off switch of the water pump 7 through an electrical signal. When the device is used, the fan 3 is started, and the fan 3 sucks air from the bottom of the fixed frame 2. The air entering the fixed frame 2 is dust-removed by the dustproof frame 8, and the dust-removed air is The cabinet 1 is inhaled into the cabinet 1 by the fan 3 to achieve heat dissipation inside the cabinet 1. A temperature sensor 12 is installed inside the cabinet 1. When the external temperature is high, the air blown in by the fan 3 is not enough to lower the temperature inside the cabinet 1. At this time, the temperature sensor 12 detects that the temperature is high. At this time, the water pump 7 in the water tank 6 is started by controlling the electric signal. The water pump 7 inputs the water in the water tank 6 into the first water cooling pipe 4 through the water delivery pipe 5, and then flows back to the water tank 6 through the water delivery pipe 5. The outside air will pass through the first water cooling pipe 4 is cooled, and the cooled air is blown into the cabinet 1, so as to dissipate heat and cool the cabinet 1 at high temperature. When the temperature drops to the set value, the temperature sensor 12 controls the water pump 7 to stop delivering water. This can achieve the function of energy saving. In addition, a second water cooling pipe 9 is installed inside the fixed frame 2. When it rains, rainwater flows from the water storage tank 10 on the top of the fixed frame 2 into the second water cooling pipe 9, and then is discharged from the drain port 11. The second water cooling pipe 9 can also cool the blown air. At this time, the water pump 7 is in a closed state.

[0028] The first water cooling tube 4 and the second water cooling tube 9 are installed side by side inside the fixing frame 2. By setting the first water cooling tube 4 and the second water cooling tube 9 to be S-shaped, the heat exchange area with the air can be increased, thereby improving the cooling effect of the air.

[0029] A filter screen 14 is installed on the surface of the water storage tank 10. Baffles 13 are installed on the four sides of the top of the cabinet body 1. An opening is provided on the left side of the baffle 13, and two groups of fixing plates 15 are symmetrically installed at the opening. Grooves are provided at the tops of the two groups of fixing plates 15, and sliders 16 are slidably embedded in the grooves. A spring 17 is installed on the side wall of the groove of the fixing plate 15, and the movable end of the spring 17 is connected to the slider 16. A water blocking plate 19 is installed on the tops of the two groups of sliders 16 through a bracket 18. The water blocking plate 19 is located between the two groups of fixing plates 15 and fits against their side walls. Strip-shaped drainage grooves are provided on the surfaces of the two groups of fixing plates 15 close to each other. A connecting frame 20 is connected to the left side of the water blocking plate 19, and the other end of the connecting frame 20 is connected to a cover plate 21. The cover plate 21 is located above the filter screen 14. By providing the filter screen 14, the filter screen 14 located on the surface of the water storage tank 10 can prevent sundries from entering and causing blockage of the second water cooling pipe 9. By providing the cover plate 21, the cover plate 21 can cover the surface of the filter screen 14 when it does not rain, thereby preventing blockage caused by the covering of sundries such as leaves. When it rains, rainwater will be stored inside the baffle 13. And as the rainwater accumulates, the water blocking plate 19 will slide to the left under the action of water pressure until the rainwater slowly flows out from the strip-shaped drainage groove on the side of the fixing plate 15. And when the water blocking plate 19 slides to the left, the cover plate 21 will be separated from the filter screen 14, so that the rainwater can enter the second water cooling pipe 9 after being filtered by the surface of the filter screen 14.

[0030] A brush plate 22 is installed at the bottom of the cover plate 21, and the brush plate 22 is in contact with the upper surface of the filter screen 14. By providing the brush plate 22, when the water blocking plate 19 pushes the cover plate 21 to slide, the brush plate 22 can brush off the sundries filtered by the filter screen 14 last time, so as to ensure the normal introduction of subsequent rainwater.

[0031] A dust-proof net 23 is installed at the bottom of the dust-proof frame 8, and lime plates 24 are equidistantly installed on the inner side wall of the dust-proof frame 8. By providing the dust-proof net 23 and the lime plates 24, the dust-proof net 23 can remove dust from the air entering the cabinet body 1, avoiding dust from entering the interior of the cabinet body 1, and the lime plates 24 can adsorb the water vapor in the air and dry and dehumidify the air entering the cabinet body 1.

[0032] The outer side wall of the dust-proof frame 8 is cylindrical. Two groups of clamping blocks 25 are symmetrically installed on the outer side wall of the dust-proof frame 8. An embedded groove adapted to the shape of the dust-proof frame 8 is provided at the bottom of the fixed frame 2, and a clamping groove adapted to the clamping block 25 is provided on the side wall of the embedded groove. The dust-proof frame 8 is installed at the bottom of the fixed frame 2 in a sliding and rotating clamping manner. By providing the clamping block 25, the whole dust-proof frame 8 is installed below the fixed frame 2 through the clamping block 25. When installing the dust-proof frame 8, the clamping blocks 25 on the left and right sides of the dust-proof frame 8 can be aligned with the sliding grooves on the lower side of the fixed frame 2 and pushed upward, and then the dust-proof frame 8 is rotated to make the clamping block 25 snap into the clamping groove. This installation method is simple and fast, providing convenience for subsequent replacement of the dust-proof net 23 and the lime plates 24.

[0033] On the surface of the front cabinet door of the cabinet body 1, there is an air outlet, and a spiral blade 26 is installed at the air outlet. A speedometer is installed inside the cabinet body 1, and the speed measurement shaft of the speedometer is connected to the central axis of the spiral blade 26. The fan 3 can rotate forward and backward. The speedometer is connected to the switch of the fan 3 through an electrical signal. By setting the spiral blade 26, when the air is discharged outward from the air outlet of the cabinet body 1, the spiral blade 26 rotates driven by the air flow, and the speedometer will monitor the rotation speed of the spiral blade 26 in real time. When the dust-proof net 23 is used for a long time, more dust will be adsorbed on the outside of the mesh holes and blocked, resulting in a decrease in the air circulation. At this time, the rotation speed of the spiral blade 26 will decrease. When the speedometer detects that the rotation speed of the spiral blade 26 decreases, it will control the fan 3 to rotate in the reverse direction. At this time, the fan 3 inhales air from the air outlet of the cabinet body 1 and blows it out from the bottom of the fixed frame 2. This setting can blow the dust-proof net 23 to remove dust, so as to ensure the normal air circulation inside the cabinet body 1.

[0034] A rain shield 27 is installed on the outside of the spiral blade 26 corresponding to the surface of the cabinet body 1. By setting the rain shield 27, the rain shield 27 can prevent rainwater from flowing into the inside of the cabinet body 1 from the air outlet of the cabinet body 1.
