[0022] During use, through the settings of the first connection flange 4 and the second connection flange 5, the pump port 3 and the infusion pipe 6 can be installed and connected;

[0023] At the bottom end of the second connection flange 5, there is a seal 502. The bottom end of the seal 502 touches the top end of the first connection flange 4. On both sides of the top end of the second connection flange 5, bolt members 501 are installed. The bottom ends of the bolt members 501 penetrate through the seal 502 and are threadedly connected to the first connection flange 4;

[0024] During use, through the setting of the seal 502, the connection position between the pump port 3 and the infusion pipe 6 can be sealed;

[0025] At the end of the pump port 3 away from the submersible pump body 2, an infusion pipe 6 is installed. At the end of the infusion pipe 6 away from the pump port 3, a filter cover 15 is installed. On the outer wall of one side of the infusion pipe 6, a float valve 16 is installed. On the top end of the bottom plate 1 on one side of the submersible pump body 2, there is a distribution box 7. The surface of the distribution box 7 is installed with a box door 8 through a hinge. At the upper end of the surface of the box door 8, there is a touch screen 9. On the surface of the box door 8 below the touch screen 9, there is an H-shaped seat body 11. At the center position of the bottom end of the H-shaped seat body 11, a lifting drive member 12 is installed. The top end of the lifting drive member 12 penetrates through the H-shaped seat body 11 and is provided with a jacking seat 13. The outer surface of one side of the jacking seat 13 touches the surface of the box door 8;
