[0017] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of protection of the utility model.

[0018] The utility model discloses a kind of anti-reverse anti-inclination submersible shaft mixed flow pump mounting structure, as shown in figure Figure 1 It includes pump body 1 and well shaft 2, the lower part of pump body 1 is equipped with guide vane body 3, and pump body 1 is installed in well shaft 2 along vertical direction.

[0019] As shown in figure Figure 2 The inner wall of well shaft 2 is symmetrically provided with two channel steels 4, and the left side or right side of well shaft 2 is provided with an outlet 10.

[0020] As shown in figure Figure 3 The bottom of well shaft 2 is radially protruding and provided with four baffles 5, and the four baffles 5 are divided into two groups, and the two groups of baffles 5 correspond to the two channel steels 4 respectively, wherein the outer walls of the two baffles 5 are respectively attached to the inner walls on the left and right sides of one channel steel 4, the upper part of guide vane body 3 is radially protruding and provided with a stop block 9, and the baffle 5 limits the stop block 9.

[0021] The structure that baffle 5 is clamped into channel steel 4 is convenient for hoisting channel steel 4 in well shaft 2, after hoisting is completed, the position of single board on the left and right sides of channel steel 4 is increased baffle 5, which plays a thickening role, to prevent baffle 5 from being damaged by impact.
