[0033] A connecting rod 4 is installed between the outer wall of the electric telescopic rod 306 and the inner left wall of the distribution cabinet body 1, and a reinforcing rod 5 is installed at the bottom of the connecting rod 4. The bottom end of the reinforcing rod 5 is connected to the inner left wall of the distribution cabinet body 1. By setting the connecting rod 4, it is not only convenient to install the electric telescopic rod 306, but also ensures the stability of the electric telescopic rod 306 during operation. By setting the reinforcing rod 5, it is ensured that the connecting rod 4 is not easy to separate from the distribution cabinet body 1, thereby ensuring that the electric telescopic rod 306 is more stable after installation; a grounding seat 10 is installed at the bottom of the distribution cabinet body 1, and a grounding piece 11 is installed between the grounding seat 10 and the distribution cabinet body 1. A plurality of reinforcement holes 12 are opened on the grounding seat 10. By setting the grounding seat 10 and the grounding piece 11, the distribution cabinet body 1 is convenient to be grounded, which improves safety. By setting the reinforcement hole 12, it is convenient to fix the grounding seat 10, thereby facilitating the fixing of the distribution cabinet body 1. A cabinet door 13 is provided on the front side of the distribution cabinet body 1.

[0034] Embodiment 2

[0035] On the basis of the first embodiment, further, as a specific implementation of the present invention, the present invention provides a temperature control mechanism for a power distribution cabinet.

[0036] Specifically, by Figure 2 It is given that the temperature control component 2 includes an electric cooling plate 201 and an electric heating plate 202 respectively installed on the top and inner bottom wall of the power distribution cabinet body 1, a single chip computer 203 is installed on the inner left wall of the power distribution cabinet body 1, and a temperature sensor 204 is installed on the inner top wall of the power distribution cabinet body 1. The electric cooling plate 201, the electric heating plate 202, the temperature sensor 204 and the fan 301 are all electrically connected to the single chip computer 203;

[0037] The single chip computer 203 stores a preset temperature value for comparison with the current temperature value transmitted by the temperature sensor 204. When the actual value is higher or lower than the preset value, it means that the temperature inside the power distribution cabinet body 1 is higher or lower, thereby starting the electric cooling plate 201 or the electric heating plate 202 to preheat or cool the power distribution cabinet body 1, thereby controlling the temperature inside the power distribution cabinet body 1 in real time.

[0038] Embodiment 3

[0039] On the basis of the second embodiment, further, as a specific implementation of the present invention, the present invention provides a temperature control mechanism for a power distribution cabinet.

[0040] Specifically, by Figure 1 and Figure 4 It is shown that a ventilation hole is opened on the right side of the power distribution cabinet body 1, and a plurality of L-shaped rods 6 are installed on both the left and right sides of the power distribution cabinet body 1, and a limit rod 7 and an elastic scraper 9 are respectively installed between the bottom and top ends of two adjacent L-shaped rods 6, and a dust filter 8 that contacts one side of the elastic scraper 9 is slidably connected between the two adjacent L-shaped rods 6;

[0041] By setting two dust filters 8, the air entering the distribution cabinet body 1 through the fan 301 and the vent is filtered. The composition of dust is relatively complex, and it sometimes provides acid radicals and metal ions that cause degradation. The floating dust particles in the dust are small in size, and their adsorption capacity is very strong. They can adsorb harmful substances in the air on their surfaces. They are acidic or alkaline, which can easily cause the circuit board and the electrical components in the distribution cabinet body 1 to become moist or even corroded. Dust adsorbed on the surface of the circuit board will reduce the insulation resistance between adjacent printed wires, affecting the normal operation of the circuit board. In severe cases, it will also cause short circuit faults, thereby extending the service life of the distribution cabinet body 1. By setting an L-shaped rod 6 and a limit rod 7, it is convenient to install the two dust filters 8 on the left and right sides of the distribution cabinet body 1 respectively. By setting an elastic scraper 9, it is not only convenient to fix the elastic scraper 9, so that the elastic scraper 9 is not easy to move away from the limit rod 7 without human power, but also the dust attached to the dust filter 8 can be scraped off during the process of taking and placing the dust filter 8, thereby ensuring the subsequent ventilation and dustproof effect of the dust filter 8.

[0042] Working principle:

[0043] The single chip computer 203 stores a preset temperature value for comparison with the current temperature value transmitted by the temperature sensor 204. When the actual value is higher than the preset value, it indicates that the temperature inside the power distribution cabinet body 1 is high, and the fan 301 is started, and the telescopic end of the electric telescopic rod 306 is controlled to continuously extend and retract, thereby driving multiple gears 304 to rotate synchronously through the rack 307, and then each guide blade 305 is rotated through multiple rotating shafts 303, thereby guiding the airflow formed by the fan 301 to blow into the power distribution cabinet body 1, so as to dissipate heat to the inner top, inner bottom and middle part of the power distribution cabinet body 1, thereby greatly improving the heat dissipation effect.

[0044] The single chip computer 203 stores a preset temperature value for comparison with the current temperature value transmitted by the temperature sensor 204. When the actual value is higher or lower than the preset value, it means that the temperature inside the power distribution cabinet body 1 is higher or lower, thereby starting the electric cooling plate 201 or the electric heating plate 202 to preheat or cool the power distribution cabinet body 1, thereby controlling the temperature inside the power distribution cabinet body 1 in real time.

[0045] By setting two dust filters 8, the air entering the distribution cabinet body 1 through the fan 301 and the vent is filtered. The composition of dust is relatively complex, and it sometimes provides acid radicals and metal ions that cause degradation. The floating dust particles in the dust are small in size, and their adsorption capacity is very strong. They can adsorb harmful substances in the air on their surfaces. They are acidic or alkaline, which can easily cause the circuit board and the electrical components in the distribution cabinet body 1 to become moist or even corroded. Dust adsorbed on the surface of the circuit board will reduce the insulation resistance between adjacent printed wires, affecting the normal operation of the circuit board. In severe cases, it will also cause short circuit faults, thereby extending the service life of the distribution cabinet body 1. By setting an L-shaped rod 6 and a limit rod 7, it is convenient to install the two dust filters 8 on the left and right sides of the distribution cabinet body 1 respectively. By setting an elastic scraper 9, it is not only convenient to fix the elastic scraper 9, so that the elastic scraper 9 is not easy to move away from the limit rod 7 without human power, but also the dust attached to the dust filter 8 can be scraped off during the process of taking and placing the dust filter 8, thereby ensuring the subsequent ventilation and dustproof effect of the dust filter 8.
