The driving end of the motor 16 is fixedly connected with the first bevel gear 17. The first bevel gear 17 and the second bevel gear 18 are meshed and connected. The inner side of the connecting frame 14 is provided with symmetrically distributed L-shaped rods 19. The interior of the electric control cabinet housing 1 is provided with symmetrically distributed guide grooves 20. One end of the L-shaped rod 19 is slidably inserted into the inner side of the guide groove 20. The bottom surface of the control system body 12 is fixedly installed with a sensor body 21.

[0020] A symmetrically distributed card plate 22 is fixedly installed on the outside of the control system body 12, and a card slot 23 corresponding to the card plate 22 is opened on the inner side of the connecting frame 14. One end of the card plate 22 is slidably inserted into the inner side of the card slot 23. A connecting block 24 is movably inserted into the bottom surface of the connecting frame 14. One end of the connecting block 24 penetrates the connecting frame 14 and is movably inserted into the inner side of the card plate 22. A first bolt 25 is threadedly installed on the bottom surface of the connecting block 24. One end of the first bolt 25 threadedly penetrates the connecting block 24 and is threadedly installed inside the connecting frame 14.

[0021] By adopting the above technical solution, the control system body 12 is supported by setting the card plate 22 to slide in the card slot 23, and then the card plate 22 and the connecting frame 14 are connected using the connecting block 24 and then fixed with the first bolt 25 to prevent the control system body 12 from loosening.

[0029] By adopting the above technical solution, the anti-skid pad 30 is provided to prevent the electric control cabinet housing 1 from slipping, thereby preventing the electric control cabinet housing 1 from being unstable in the humid environment of the basement.

[0030] Working principle: First, when the water level in the basement rises after a heavy rain, as the water level continues to rise, it slowly contacts the sensor body 21. The signal transmission through the sensor body 21 then drives the motor 16 to rotate the first bevel gear 17. The rotation of the first bevel gear 17 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the lifting screw 13 to rotate. The lifting screw 13 drives the connecting frame 14 to rotate. The connecting frame 14 is guided by the L-shaped rod 19 sliding in the guide groove 20 to become lifted, so that the lifting screw 13 rotates to drive the connecting frame 14 to rise, and the connecting frame 14 drives the control system body 12 to rise away from the water source, and then the lifting screw 13 is turned into a lifting frame. This prevents water from invading the control system body 12 and causing damage to the control system body 12, and prevents a malfunction that causes the control system body 12 to not operate normally, thereby better ensuring the safety protection of the control system body 12 and adding safety measures. The card plate 22 slides in the card slot 23 to support the control system body 12, and then the card plate 22 and the connecting frame 14 are connected using the connecting block 24 and then fixed with the first bolt 25 to prevent the control system body 12 from loosening. Removing the first bolt 25 facilitates the removal of the control system body 12, thereby facilitating the removal of the control system body 12 for replacement or maintenance inspection after a malfunction or aging.
