Description

Technical Field

[0001] The invention relates to a submersible electric pump, in particular to an inclined wellbore submersible pump. Background Art

[0002] In recent years, submersible wellbore pumps have been increasingly used in urban drainage and agricultural irrigation projects due to their simple structure, easy maintenance, and low project investment. Since submersible pumps are primarily hoisted into the wellbore by wire rope, they must be hoisted out of the wellbore for maintenance. Currently, most submersible pumps require considerable effort to hoist, preventing the wire rope from freely controlling the height and speed of the pump within the wellbore during the lifting or lowering process. There is a pressing need for a submersible pump equipped with a pulley mechanism that facilitates rapid installation and lifting, particularly in deep wells or where frequent maintenance is required, significantly reducing manual labor.

[0003] With the acceleration of global agricultural modernization and the continued advancement of infrastructure construction, demand for efficient and convenient submersible pumps continues to grow. Submersible pumps with pulleys are particularly popular in water-scarce areas due to their ease of installation and maintenance. With growing market demand and ongoing technological innovation, this product has a promising market outlook. Summary of the Invention

[0004] In order to solve the above technical problems, an inclined wellbore submersible pump is provided, which is easy to install and maintain and can help reduce manual labor intensity and work efficiency. During installation and maintenance, the submersible pump body slides up and down in the wellbore through ropes and pump trucks, which improves the stability of the submersible pump body, reduces the pulling force of the submersible pump body on the rope, and facilitates the lifting and lowering of the submersible pump body in the wellbore, thereby improving the reliability of the submersible pump body.

[0005] The technical solution adopted to achieve the above-mentioned purpose is: an inclined wellbore submersible pump, which includes a submersible pump body, a wellbore, and a pump truck. The pump truck is mainly composed of a support seat, a roller and a roller shaft; the support seat is made of a whole piece of material, and a roller shaft is provided on the left and right sides below the support seat. The roller is sleeved on the roller shaft. The roller protrudes from the outside of the support seat to support the submersible pump body and the submersible pump body to move up and down in the wellbore; the pump truck is in the inner circle of the support seat.

[0006] Furthermore, a groove is provided on each of the left and right sides below the support seat, and a roller shaft and a roller are provided in the groove.

[0007] Furthermore, the two sides of the roller shaft are linear or symmetrical groove-shaped structures, and the grooves are inserted into the grooves of the support seat on both sides and connected to the support seat.

[0008] Furthermore, the pump truck is also provided with a clamp, which is connected to the support seat to fix the pump truck to the periphery of the submersible pump body. The pump truck is used to support the submersible pump body to move up and down in the inclined wellbore.

[0009] Furthermore, the clamp, support base, roller and roller shaft in the pump truck are composed of at least two groups.

[0010] Furthermore, the pump truck can also remove the clamp setting and connect the two support seats with rollers and roller shafts respectively installed through flanges, so that the pump trucks on the submersible pump body are changed from two groups to four groups.

[0011] Furthermore, the guide vane of the submersible pump body is provided with a conical seat near the outlet flange, and the conical seat is cooperatively connected with the wellbore.

[0012] The beneficial effects of the present invention are as follows: a pump truck is mounted on a submersible pump body, the pump truck primarily consisting of a support base, rollers, and roller shafts; the support base is cut from a single piece of material, with roller shafts disposed on the left and right sides below the support base. Rollers are mounted on the roller shafts, protruding from the outside of the support base to support the submersible pump body and allow for up and down movement. This allows the submersible pump body to slide up and down more smoothly within the wellbore during installation and maintenance, improving the stability of the submersible pump body during installation and maintenance, reducing the tension exerted by the submersible pump body on the rope, facilitating the lifting and lowering of the submersible pump body within the wellbore, and improving the reliability of the submersible pump body. Furthermore, the roller shaft is designed as a forked structure, which controls the clearance between the support base and the roller shaft, preventing the roller shaft from becoming stuck due to welding deformation. The distance between the roller and the center can also be adjusted before welding. Furthermore, the roller shaft structure can be a round shaft. BRIEF DESCRIPTION OF THE DRAWINGS
