It should be noted that: the outer cross section of the plurality of reaction rotating blades 204 adopts a hook-shaped structure, so that the main purpose is to enlarge the contact area with overflowed water, and thus larger water impact force is obtained.
In this embodiment, the specific working principle is as follows:
it should be noted that the device is disposed outdoors, and the environment is specifically considered to be a rainy weather, wherein the rainy weather comprises thunder and rain weather, in addition, the insulating gas reaction substance stored in the reaction rotary vane 204 is a substance such as an alkali block, the insulating gas reaction substance generates with water after being released, and hydrogen and alkaline solution can be generated.
Referring to fig. 1, it can be seen that, when the weather of the rainy day comes, in the process that the rainwater continuously falls, as the four sides of the rain storage shielding box 102 are provided with an arc structure, the rebound force of the falling rainwater is reduced relative to the planar structure, so that the rainwater can be contacted with the side wall of the rain storage shielding box 102 at a softer angle, and the rebounded water is not sputtered outwards but is sputtered to the inside of the rain storage shielding box 102 for storage under the arc structure, and in addition, the maximum area of the horizontal section of the rain storage shielding box 102 is larger than the maximum area of the cross section of the switch cabinet 100, so that the switch cabinet 100 is directly shielded by the rainwater under the condition of the rainy day.
Referring to fig. 2, 3, 4 and 5, it can be known that the side wall section of the overflow pipe 103 is provided with an inclined structure, so as to ensure that the impact force generated when the rain storage shielding box 102 stores overflowed rain water is increased, thereby driving the reaction rotating vane 204 to rotate, when the rain storage shielding box 102 is in a small rain climate, the water level overflow rate in the rain storage shielding box 102 is slower, the movement rate of the reaction rotating vane 204 is lower, the internal insulating gas reactant is not extruded to release the reactant baffle 205 due to lower centrifugal force, and the occurrence probability of current breakdown phenomenon is lower because the reactant is classified in a small rain day at this time, insulating gas is not generated to insulate the switch cabinet 100, but at this time, the reaction rotating vane 204 still is in a rain weather, and the first-stage dehumidification mechanism 300 is driven to operate in the movement process, thereby performing preliminary blowing dehumidification treatment on the interior of the switch cabinet 100;
as can be seen from the above figures and fig. 6 and 7, when a heavy rain or thunder weather arrives, the rate of rainwater overflowing inside the rainwater storage shielding tank 102 is high, the impact force of overflowing rainwater when being discharged through the overflow pipe 103 is high, the moving rotation speed of the reaction rotary vane 204 is increased, and correspondingly, the centrifugal force received by the reaction rotary vane 204 is increased, so that the insulating gas reactant is discharged through the plurality of reactant through holes 208, and due to the arrangement of the plurality of reactant through holes 208, no blocking phenomenon occurs, when the accumulated insulating gas reactant is accumulated at the end of the reactant baffle 205, the section of the reactant baffle 205 is stretched by the extrusion force, the insulating gas reactant is discharged until the reactant baffle 205 is opened, the insulating gas reactant falls into the water at the lower end of the reaction tank 201 and reacts with the water at normal temperature, hydrogen is generated, and the molecular mass of the hydrogen is reduced, so that the insulating gas reactant is discharged to the upper end of the switch cabinet 100 through the insulating gas exhaust pipe 209, so that the current released by lightning is insulated and protected, the first-stage current is high-strength, the current and the dehumidification efficiency of the switch cabinet 300 cannot be increased, and the rate of the dehumidification mechanism 300 cannot be increased, and the inside the switch cabinet is increased along with the weather is increased;
according to the overflow rate of rainwater in the rainwater storage shielding box 102, the weather is judged in real time, dehumidification protection with different functions is achieved in the switch cabinet 100 in the judging process, namely, high-efficiency dehumidification is achieved in heavy rain weather, low-efficiency dehumidification is achieved in light rain, insulating gas is selectively generated through judging results of different weather, namely, light rain is free from generating gas, and the heavy rain thunderstorm weather is insulated and protected, so that the influence of current breakdown on components in the switch cabinet 100 is avoided.
In addition, according to different rainfall, the basic storage rain inside the rain storage shielding box 102 can evaporate under the sun irradiation after sunny days, and the most comprehensive place of sunlight irradiation is the top end of the switch cabinet 100, so that the box cooling function of the switch cabinet 100 under sunny days is realized by utilizing the evaporation effect of collecting the rainwater, the normal operation of components inside the switch cabinet 100 under high-temperature weather is ensured, and the water and liquid supply can be manually carried out in the subsequent absence of water, so that the conventional cooling function is realized.
The alkaline solution generated inside the final reaction tank 201 is discharged into the wastewater treatment pipe through the reaction liquid discharge pipe 202.
Example two
In comparison with the first embodiment, although the dehumidification adjustment of the functionality can be performed according to the weather, the structural singleness and the convention of the dehumidification function still exist, and based on this condition, another embodiment is proposed, which further includes, on the basis of the first embodiment:
the conversion mechanism 400 is arranged in the switch cabinet 100, and the conversion mechanism 400 is used for driving and converting the driving force generated by the insulation protection mechanism 200 to generate the pushing force required for subsequent work;
the secondary dehumidification mechanism 500, the secondary dehumidification mechanism 500 is disposed on a side wall of the conversion mechanism 400, and the secondary dehumidification mechanism 500 is configured to receive the pushing force after the conversion mechanism 400 converts.
Further explanation is made with reference to fig. 9 and 10;
