as an embodiment of the present invention, two connecting blocks 13 are symmetrically arranged on both sides of the housing 1, a guiding rod 14 is fixedly connected between each two connecting blocks 13, a U-shaped shaking strip 15 is commonly arranged on the two guiding rods 14 in a penetrating manner, the upper end of the U-shaped shaking strip 15 is elastically connected with the two connecting blocks 13 located above through two shaking springs 16, a cleaning brush is arranged on the side wall of the U-shaped shaking strip 15 close to the two ventilation openings 17, a magnetic block 35 is fixedly connected to the right end of the hollow strip 7, the side of the U-shaped shaking strip 15 close to the magnetic block 35 is made of iron, and the other parts are made of lighter materials, so that the gravity of the whole U-shaped shaking strip 15 is lighter, and in order to ensure that the nozzle 33 can swing in this embodiment, the air inlet end of the nozzle 33 is made of a hose.

In the normal use process, under the action of the gravity of the U-shaped shaking strip 15 in the initial state, the shaking spring 16 is in a slight stretching state;

when the electrical cabinet is used, passive heat dissipation is carried out through the vent 17, normal use of the electrical cabinet can be met, when the filter screen 18 at the vent 17 is blocked, passive heat dissipation is poor at the moment, the heat dissipation effect is influenced, after the electrical cabinet works, the temperature in the installation chamber 2 can be raised, so that the heat expansion liquid is transmitted to the thermal expansion liquid through the heat conducting plate 21, the thermal expansion liquid is expanded (when the temperature is higher than 68 ℃, normal hexane solution can be gasified and expanded), the current conducting plate 24 is further contacted with the two first electricity connecting pieces 22, and at the moment, the motor 9 and the refrigerating piece 31 work;

the motor 9 drives the fan blades 29 to rotate to generate wind from top to bottom, and through the arrangement of the connecting hose 10, circulating wind of the installation chamber 2 → the dust removing cavity 26 → the hollow strip 7 → the installation chamber 2 can be generated, the circulating wind enters the installation chamber 2 through the hollow strip 7 and is realized by the spray heads 33, the wind generated by the spray heads 33 can blow the electric element to blow off dust on the surface of the electric element, and due to the arrangement of the refrigerating sheet 31, heat can be dissipated inside the installation chamber 2 while blowing dust;

the dust blown off can enter the dust removal cavity 26 along with the circulating air flow and is filtered by the dust filter plate 28, so that the dust is prevented from being attached to the electric element again, the motor 9 rotates to drive the reciprocating screw rod 6 to rotate through the transmission structure 12, the reciprocating screw rod 6 rotates to move up and down through the sliding block 4, the hollow bar 7 and the plurality of spray heads 33 are driven to blow air in a vertically reciprocating mode, the integral electric element is subjected to heat dissipation and dust removal, and the heat dissipation and dust removal effects are good;

in the process that the hollow strip 7 moves downwards, when passing through the U-shaped shaking strip 15, the U-shaped shaking strip 15 moves downwards under the action of magnetic force, when the U-shaped trembler 15 moves down to the lower end face of the vent 17, the limit state at which the two trembler springs 16 are stretched, when the hollow bar 7 moves downwards continuously, the U-shaped shaking bar 15 is driven by the shaking spring 16 to move back under the elastic action of the shaking spring 16 (because the U-shaped shaking bar 15 cannot move downwards continuously, the magnetic action of the U-shaped shaking bar 15 is gradually smaller than the elastic action of the shaking spring 16), under the action of the inertia of the U-shaped shaking strip 15, shaking can occur for many times, and the state of the figure 1 is finally recovered, in the shaking process, the cleaning brush can continuously brush the two filter screens 18, the filter screen 18 is dredged and cleaned to ensure that the filter screen is in a better ventilation state (similarly, the hollow strip 7 moves upwards and is also shaken);

because the arrangement of the refrigerating sheet 31 and the filter screens 18 are dredged, the temperature in the installation chamber 2 can be slowly reduced (because the temperature transmission takes time, the temperature of the thermal expansion liquid is not immediately reduced, namely the conducting time lasts for a period of time, and the ash removal and heat dissipation can be completely operated), and because the two filter screens 18 are exposed outside, the dust collecting speed on the filter screens 18 is far higher than the dust collecting speed of the electric elements in the installation chamber 2, when the filter screens 18 are blocked, the influence of the collected dust on the electric elements is in a small state, and the cleaning is carried out at the moment, so that the condition that a large amount of dust is attached to the electric elements can be avoided;

it should be mentioned here that, when a short circuit or abnormal operation occurs in the installation chamber 2, the temperature in the installation chamber 2 also rises (but the rising speed is high), at this time, the ash cleaning and heat dissipation mechanism is also triggered, but because the heat dissipation speed of the heat dissipation mechanism is not enough to meet the heat release of the short circuit or abnormal operation in the installation chamber 2, the thermal expansion liquid will expand continuously, and two second electrical connecting pieces 23 are in contact, and the alarm 19 gives an alarm to remind surrounding personnel of emergency repair in time.

Example 2

Referring to fig. 6-7, the present embodiment is different from embodiment 1 in that a cross bar 34 is rotatably connected to two connecting plates 32, the outer side of the right end portion of the cross bar 34 is elastically connected to the right connecting plate 32 through a torsion spring 37, the right end of the cross bar 34 penetrates through the right connecting plate 32 and is fixedly connected to a gear 38, a rack 36 engaged with the gear 38 is disposed between the inner top and the inner bottom of the installation chamber 2, and the position of the teeth on the rack 36 is as shown in fig. 11, and the teeth are intermittently disposed, so that the nozzle 33 can swing under the engagement of the torsion spring 37, thereby increasing the range of dust removal and heat dissipation.

In this embodiment, in the process of moving the hollow bar 7 up and down, taking down as an example, when the gear 38 contacts the toothed portion on the rack 36, the gear 38 drives the plurality of nozzles 33 to rotate upward through the cross rod 34 and accumulate force on the torsion spring 37, and when the gear 38 leaves the toothed portion on the rack 36, the plurality of nozzles 33 will move back under the elastic action of the torsion spring 37, so that the plurality of nozzles 33 continuously swing in the process of moving up and down, thereby further improving the dust removal and heat dissipation range.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
