[0036] Working principle:

[0037] Motor 2 drives fluid suction and compression:

[0038] After the motor 2 is started, it is connected to the pump body 4 through the transmission shaft, and the power is transmitted to the screw (or impeller) inside the pump body 4. When the screw (or impeller) rotates in the pump body 4, a sealed chamber is formed, which continuously sucks in and compresses the fluid, pushing the fluid from one end to the other.

[0039] Stabilization mechanism 7 Stabilization process:

[0040] By rotating the handle 721, the worm 720 is driven to rotate, and the worm 720 drives the worm wheel 719 to rotate, thereby driving the active bevel gear 717 to rotate;

[0041] The driving bevel gear 717 meshes with the driven bevel gear 716 to rotate the horizontal shaft 714 and the transmission gear 715, and the transmission gear 715 meshes with the tooth groove 711 on the slide bar 708 to move the slide bar 708 in the slide groove 707;

[0042] The movement of the slide bar 708 drives the bidirectional tooth plate 709 to move, and the bidirectional tooth plate 709 drives the small gear 706 to rotate through the meshing relationship, thereby driving the large gear 705 to rotate;

[0043] The rotation of the large gear 705 drives the one-way toothed plate 722 to move, and the one-way toothed plate 722 pushes the arc-shaped clamping block 724 toward the liquid outlet pipe 6 through the connecting block 723, thereby clamping and fixing the liquid outlet pipe 6;

[0044] Fluid removal and fixation:

[0045] The compressed fluid enters the liquid outlet pipe 6 through the elbow 5 and is discharged along the liquid outlet pipe 6;

[0046] The stabilizing mechanism 7 ensures that the liquid outlet pipe 6 remains stable during the operation of the pump, and prevents it from loosening or falling off due to vibration.

[0047] Functions of the side groove 8 and the positioning block 10:

[0048] The side groove 8 formed on the mounting plate 1 corresponding to the point where the liquid outlet pipe 6 passes through, and the positioning block 10 connected by the fixing bolt 9 further enhance the stability of the liquid outlet pipe 6 to prevent it from shaking up and down;

[0049] The reinforcement function of the clamp 729 is:

[0050] The clamp 729 installed on the side plate 727 through the hinge 728 includes a fixed clamp 7291, a movable clamp 7292, a locking bolt 7293, and a locking nut 7294, which are used to fix the stabilizing mechanism 7 outside the branch pipe 3 to ensure the stability of the overall structure.

[0051] In summary, the stable submersible pump suitable for high-viscosity fluids provided by the present invention drives the pump body 4 to rotate through the motor 2 to achieve the suction, compression and discharge of the fluid. At the same time, through the innovatively designed stabilizing mechanism 7, the liquid outlet pipe 6 is clamped and fixed, which effectively improves the stability and safety of the pump during operation.
