Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0020] Please refer to Figures 1-4 The application discloses an AC connection electrical equipment flexible intelligent adjusting device which is connected with an AC power source and is used for scheduling and managing power, and the device comprises a heat dissipation system 1, the heat dissipation system 1 comprises a fan 2 and a circuit switch 3, the wind power grade of the fan 2 is controlled by the circuit switch 3, the circuit switch 3 is provided with a limiting channel 31 on the surface, recesses are formed in the inner surface of the limiting channel 31, the number of the recesses is two, a high-grade switch 32 and a low-grade switch 33 are respectively arranged in the recesses, the high-grade switch 32 and the low-grade switch 33 are connected with an electric wire 5 in the circuit switch 3, the structure of the electric wire 5 in the circuit switch 3 is designed according to actual installation conditions and is not shown in the drawings, a temperature sensing push rod 4 is arranged in the limiting channel 31, the temperature sensing push rod 4 is provided with a synapse 41 on the outer surface of one end in the limiting channel 31, the temperature sensing push rod 4 changes the length thereof according to the change of the ambient temperature, the temperature sensing push rod 4 is made of a memory metal material, specifically a nickel-titanium alloy, and the temperature sensing push rod 4 has a movement freedom degree in the limiting channel 31 when being stretched or retracted, the temperature sensing push rod 4 is hollow and stores the electric wire 5, one end of the electric wire 5 is connected to the synapse 41 and the other end is connected to a power source, the position of the power source is arranged according to actual installation conditions, the power source can be an AC power source or a battery, the specific path of the electric wire 5 is not shown in the drawings, and the circuit switch 3 is connected with the fan 2 through the electric wire 5. The AC connection electrical equipment flexible intelligent adjusting device controls the fan 2 of the heat dissipation system 1 through the circuit switch 3 which is provided with the high-grade switch 32 and the low-grade switch 33, the power of the fan 2 can be flexibly controlled, the temperature sensing push rod 4 made of the memory metal material is designed to be stretched with the increase of the temperature, when the adjusting device faces a power peak period, the work load and the heat production increase, the overall temperature in the equipment increases, the temperature sensing push rod 4 is affected by the change of the ambient temperature and extends into the limiting channel 31, the synapse 41 originally connected with the low-grade switch 33 is pushed to the high-grade switch 32, the power of the fan 2 increases, and the effect of the heat dissipation system 1 increases, when the device is in a power valley period, the work load of the intelligent adjusting device decreases, the heat in the equipment decreases, the temperature sensing push rod 4 retracts and returns to the position connected with the low-grade switch 33, the fan 2 is switched to low power, and the effect of saving energy is achieved.
[0021] Please refer to Figures 1-2When the temperature rises, the length of the temperature-sensing push rod 4 increases. The position of the high-power switch 32 is closer to the inside of the limit channel 31 than that of the low-power switch 33. The temperature-sensing push rod 4 is fixedly connected to a limit plate by welding at one end outside the limit channel 31. The limit plate has no degree of freedom of movement. Therefore, when the internal temperature of the equipment rises, the temperature push rod becomes longer, pushing the contact 41 inward, so that the contact 41 is connected to the high-power switch 32.
[0022] Please see Figure 2 A spring 42 and a protective sleeve 43 are provided between the temperature-sensing push rod 4 and the contact 41. The contact 41 has a degree of freedom of movement along the direction of the spring 42, so that when the temperature-sensing push rod 4 moves, the inside of the limiting channel 31 will not squeeze the contact 41. When the contact 41 enters the groove area, it can fit against the switch under the pushing force of the spring 42. The protective sleeve 43 is connected to the hollow part inside the temperature-sensing push rod 4. The protective sleeve 43 contains the wire 5. The protective sleeve 43 is made of insulating elastic material such as rubber, and has a certain degree of extensibility while ensuring safety. This structure is achieved through the connection between the contact 41 and the temperature-sensing push rod 4. The addition of spring 42 allows the temperature-sensitive push rod 4 to deform under slight temperature changes. Spring 42 and the intermediate elastic insulating protective sleeve 43 provide a certain amount of movement, ensuring the connection between the contact 41 and the switch is not affected by minor temperature fluctuations. The groove containing the high-side switch 32 has an outward-facing slope, while the groove containing the low-side switch 33 has an inward-facing slope. This design allows the contact 41 to move slowly with the slope under the influence of the temperature-sensitive push rod 4, preventing compression and collision. This increases the stability and durability of the structure.
[0023] In summary, as described in 1-4, this AC-connected electrical equipment flexible intelligent adjustment device controls the fan 2 of the heat dissipation system 1 through a circuit switch 3 equipped with a high-power switch 32 and a low-power switch 33, achieving flexible adjustment of the fan 2's power. Utilizing the characteristic that shape-memory metal changes with temperature, the temperature-sensing push rod 4, made of shape-memory metal, is designed to extend as the temperature rises. This design allows the device to extend into the limit channel 31 as the overall internal temperature rises during peak electricity consumption periods, when workload and heat generation increase. The push rod 4, influenced by changes in ambient temperature, extends into the limit channel 31, pushing the contact 41, originally connected to the low-power switch 33, to the high-power switch 32, thus increasing the fan 2's power and improving the heat dissipation system 1's effectiveness. During off-peak electricity consumption periods, the intelligent adjustment device's workload decreases, the internal heat decreases, and the push rod 4 retracts, returning to its position connected to the low-power switch 33, switching the fan 2 to low power, achieving energy savings.
