SUBMERSIBLE PUMP SUPPORT ROD STABILIZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/200880
Kind Code:
A1
Abstract:
Disclosed is a submersible pump support rod stabilizing device, comprising: a submersible pump (1), an upper support rod (2), a lower support rod (3), etc., wherein the upper support rod (2) and the lower support rod (3) are respectively provided on an upper portion of one side and on a lower portion of the other side of the submersible pump (1). The upper and lower support rods (2, 3) are respectively provided with a bend (7, 8) bending towards the side of the submersible pump (1), and a small segment of rod head (9, 10). A circular ring (11, 12) is provided on the small segment of rod head (9, 10), and an inclined edge (13) is provided on the rod head (9, 10). A rope (14) is provided, two ends thereof being respectively fixed on the circular rings (11, 12) on the rod heads (9, 10) of the upper and lower support rods on one side of the submersible pump (1), and the rope (14) is provided with a pulley (15.; A pull rope (16) is pulled upwards via the pulley (15), and the other end of the pull rope (16) is fixed at the mouth of a well, such that the inclined edges (13) on the rod heads (9, 10) of the upper and lower support rods both push against a well wall (18), thus stabilizing the submersible pump (1). A further pull rope (17) is provided. One end of the pull rope (17) is fixed on the circular ring (12) on the rod head (10) of the lower support rod on the other side of the submersible pump (1), and the other end is tied and fixed on the circular ring (11) on the rod head (9) of the upper support rod. The pull rope (17) is pulled upwards so that the inclined edges (13) on the rod heads (9, 10) of the upper and lower support rods are disengaged from the well wall (18) to release the submersible pump (1), and the pull rope is continuously pulled so that the submersible pump (1) is lifted out of the well.
