[0023] An embodiment of the present utility model provides a pilot-wire load combination device, as Figures 1-6As shown in the figure, the pilot load combination device includes: a pilot load combination device body 1 including a middle cabinet 2, a left cabinet 3, and a right cabinet 4, wherein a load switch 5 is arranged inside the middle cabinet 2; a bottom plate 6 fixedly installed at the bottom of the pilot load combination device body 1, and a housing 7 is arranged below the bottom plate 6; a fan 8 fixedly installed on the inner wall of the housing 7; a straight pipe 9 fixedly installed on the housing 7, and the top end of the straight pipe 9 extends into the middle cabinet 2; two communicating pipes 10 fixedly installed on the housing 7, and one ends of the two communicating pipes 10 respectively extend into the left cabinet 3 and the right cabinet 4; a dust-proof net 11 arranged below the housing 7 for blocking dust; and a plurality of fixing mechanisms assembled on the housing 7 for fixing the dust-proof net 11.

[0024] In this embodiment, during the operation of the pilot load combination device body 1, a large amount of heat will be generated by the electronic components and circuits in the middle cabinet 2, the left cabinet 3, and the right cabinet 4. These heats cannot be quickly dissipated only through the heat dissipation holes. In order to improve the heat dissipation efficiency, the fan 8 needs to be started. After the fan 8 is started, gas can be injected into the interiors of the middle cabinet 2, the left cabinet 3, and the right cabinet 4 through the straight pipe 9 and the two communicating pipes 10. The addition of these gases will increase the flow rate of the internal gas, and then accelerate the speed of the internal heat dissipating from the heat dissipation holes, effectively improving the performance and service life of the electronic components, and the use effect is better. The gas sucked by the fan 8 will be filtered by the dust-proof net 11, which can effectively reduce the dust entering the device interior. When the dust-proof net 11 is dirty and needs to be removed for cleaning, a plurality of fixing mechanisms can be used to loosen the dust-proof net 11. After loosening, the dust-proof net 11 can be directly pulled out by hand, and the operation is relatively simple.

[0025] In a further preferred embodiment of the present utility model, the fixing mechanism includes: a support block 12 welded on the housing 7, and a screw 13 is threadedly installed on the support block 12; a sliding rod 14 slidably installed on the support block 12; a clamping plate 15 fixedly installed on the sliding rod 14, the top of the clamping plate 15 is rotatably connected to the bottom end of the screw 13, and the clamping plate 15 is adapted to the dust-proof net 11.

[0026] In this embodiment, the fixing mechanism is used to fix the dust-proof net 11. When the dust-proof net 11 needs to be removed for cleaning, rotate the screw 13, and the screw 13 will drive the clamping plate 15 to move vertically. At this time, the sliding rod 14 connected to the clamping plate 15 will also slide vertically on the support block 12. When the clamping plate 15 moves to the corresponding position, the dust-proof net 11 can be directly extracted from the clamping plate 15, and then the next cleaning work can be carried out.

[0027] In a further preferred embodiment of the present utility model, a plurality of support plates are fixedly installed at the bottom of the bottom plate 6, and all the support plates are rectangular.

[0028] In this embodiment, through a plurality of rectangular support plates, the housing 7 can be kept at a certain distance from the ground to prevent the fan 8 from malfunctioning during use.

[0029] In a further preferred embodiment of the present utility model, two connecting blocks are fixedly installed at the bottom of the bottom plate 6, and the bottoms of the two connecting blocks are fixedly connected to the top of the housing 7.

[0030] In this embodiment, the housing 7 can be stably fixed to the bottom of the bottom plate 6 through the two connecting blocks, so that the housing 7 can maintain good stability during use.

[0031] In a further preferred embodiment of the present utility model, knobs are fixedly installed at the tops of the plurality of screws 13, and a plurality of anti-slip pads are fixedly installed on the plurality of knobs.

[0032] In this embodiment, through the combined use of the knob and the anti-slip pad, personnel can conveniently adjust the position of the screw 13 on the support block 12, thereby realizing the fixing or loosening of the dust-proof net 11.

[0033] In a further preferred embodiment of the present utility model, two positioning grooves are formed at the bottom of the housing 7, positioning blocks 16 are arranged inside the two positioning grooves, and the bottoms of the two positioning blocks 16 are fixedly connected to the dust-proof net 11.

[0034] In this embodiment, through the combined use of the two positioning grooves and the two positioning blocks 16, when the dust-proof net 11 is not lowered to the corresponding height, the dust-proof net 11 can be prevented from being pulled out of the clamping plate 15.

[0035] In a further preferred embodiment of the present utility model, cabinet doors 17 are arranged on the middle cabinet 2, the left cabinet 3 and the right cabinet 4, and a plurality of heat dissipation holes for heat dissipation are formed in the plurality of cabinet doors 17.

[0036] In this embodiment, the plurality of cabinet doors can prevent external dust, impurities or other unexpected substances from entering the interior of the device, and the plurality of heat dissipation holes can dissipate the heat generated inside the device, avoiding performance degradation or damage caused by overheating.

[0037] In summary, compared with the related technologies, in this solution, multiple heat dissipation holes can dissipate the heat generated inside the middle cabinet 2, the left cabinet 3, and the right cabinet 4. By the combined use of the housing 7, the fan 8, the straight pipe 9, and the two connecting pipes 10, gas can be injected into the interiors of the middle cabinet 2, the left cabinet 3, and the right cabinet 4. The addition of this gas will accelerate the flow rate of the internal gas, and thus accelerate the speed at which the internal heat dissipates from the heat dissipation holes, effectively improving the performance and service life of the electronic components, and the use effect is good. The dust-proof net 11 can filter the gas sucked by the fan 8, effectively reducing the entry of dust into the interior of the pilot protection combined device body 1. The fixing mechanism enables personnel to conveniently remove and install the dust-proof net 11, facilitating the cleaning and maintenance of the dust-proof net 11. Through multiple rectangular support plates, the housing 7 can be kept at a certain distance from the ground to prevent the fan 8 from malfunctioning during use.
