In order to protect the infrared emitting module and the infrared receiving module in the collection tank, the lower surface of the left sealing plate 13 is fixedly installed with an infrared emission module that emits infrared light, and the bottom of the collection tank accommodates a float that can float on the rainwater level. Plate 12, the left upper surface of the floating plate 12 is fixedly installed with an infrared receiving module for receiving infrared light emitted by the infrared transmitting module. When the floating plate 12 is at the bottom of the collection tank, it means that the amount of rainwater inside the collection tank has reached the warning position, and At this time, the infrared emitting module on the left sealing plate 13 is just aligned with the infrared receiving module on the floating plate 12, so as to issue a warning signal, the bottom of the collecting tank is recessed inward, and the collecting tank is fixedly installed with a pumping device. The rainwater in the collecting tank is extracted by the water pumping device. The switchgear main body 11 is provided with a temperature sensor 27 for monitoring the heating temperature, and the right outer wall of the outer case 1 is provided with a control assembly 6 that is electrically connected to the temperature sensor 27.

The waterproof shell The upper surface of the second 18 is provided with a second through hole for light to enter. When there is still rainwater in the collecting tank, the infrared transmitting module and the infrared receiving module are not aligned, and the infrared receiver 17 cannot receive the infrared light emitted by the infrared transmitter 14. The water pumping device can continue to pump water to cool down. When the rainwater level is lower than the bottom of the collection tank, the floating plate 12 is at the bottom of the collection tank. At this time, the infrared transmitting module and the infrared receiving module are just aligned, and the infrared receiver 17 receives the infrared emission. After the infrared light emitted by the device 14, the signal is fed back to the control assembly 6, and then the control assembly 6 closes the water pumping device.

In order to make the floating board 12 float more easily, the floating board 12 is densely covered with a plurality of water guide holes, so that rainwater can pass through the water guide holes, so that the floating board 12 always floats on the liquid surface. effective protection.

In order to rapidly cool down the main body 11 of the switchgear, a water pumping device is arranged in the collecting tank. The water pumping device includes a pump 20.

The front end face of the switchgear is hinged with a box door 2, and the main body 11 of the switchgear can be maintained and inspected by opening the box door 2.

The working principle and use process of the present invention are as follows: in rainy weather, the rainwater enters the collection tank through the rainwater collection port 8, and is then used to cool the switchgear main body 11. Since there is still rainwater in the collection tank, the infrared emission module and the infrared The receiving module has not been aligned, the infrared receiver 17 cannot receive the infrared light emitted by the infrared transmitter 14, and the pumping device can work normally;

When the temperature of the switchgear main body 11 is too high, the temperature sensor 27 on the switchgear main body 11 feeds back a signal to the control assembly 6, and the control assembly 6 issues an alarm through the indicator light 25 and the horn 26, and at the same time controls the pump 20 to put the collection tank into the The rainwater is extracted, so that the rainwater is transported to the atomizing nozzle 10 along the water conduit 22, and after being atomized by the atomizing nozzle 10, it is sprayed to the outer wall of the switchgear main body 11, and the switchgear main body 11 is cooled down. Part of the heat is dissipated, and the dripping sewage is discharged from the drain port 3 to take away part of the heat and achieve the purpose of rapid cooling;

When the water level of the rainwater is gradually lower than the bottom of the collection tank after the pump 20 has pumped for a period of time, the floating plate 12 will reach the bottom of the collection tank with the decrease of the liquid level. The infrared receiving module is just aligned, and the infrared receiver 17 feeds back the signal to the control assembly 6 after receiving the infrared light emitted by the infrared transmitter 14, and then the control assembly 6 closes the pump 20, protects the pump 20, and passes the indicator light 25 at the same time. And the horn 26 gives out an alarm, prompting the need to add water to cool down.
