Description

Technical Field

[0001] This utility model relates to the field of deep-water pump technology, and in particular to a submersible pump pipeline fixing device and the submersible pump thereof. Background Technology

[0002] Submersible pumps (such as deep-well submersible pumps) play a crucial role in deep-well operations on offshore platforms or in mining and oil fields, responsible for lifting fluids from the bottom of the well to the surface. During submersible pump operation, the equipment needs to be lowered from the wellhead to the bottom of the well. The motor is usually located at the bottom of the pump body and requires a cable to ensure its normal operation. Furthermore, in offshore platform applications, additional chemical dosing lines are needed for marine life control.

[0003] However, in deep well operations, the cables and dosing lines used are typically very long and large in diameter. During pump lowering or operation, these long and thick cables and dosing lines are prone to swaying or shifting, which may cause uneven stress at the sealing interface with the submersible pump motor, even affecting the sealing effect, causing leakage, and ultimately leading to water ingress into the motor and damage to the equipment. Similarly, swaying or pulling of the dosing line may cause the line itself to break, affecting the normal operation of the dosing function, and even causing environmental pollution or safety hazards.

[0004] Therefore, a device is needed to effectively secure the submersible pump pipeline. Utility Model Content

[0027] In the description of this utility model, the first direction and the second direction are perpendicular or approximately perpendicular to each other, and the second direction is the radial direction of the water supply pipe flange.

[0028] Reference Figure 2 A submersible pump pipeline fixing device according to an embodiment of the present invention includes: a bracket 1 and a fixing component 2;

[0029] The bracket 1 has a mounting hole 11 that extends through the first direction x. The two ends of the fixing member 2 are respectively connected to the bracket 1, and the fixing member 2 protrudes from one side of the bracket 1 in the second direction y. A through hole 3 for fixing the pipeline 7 is formed between the fixing member 2 and the side of the bracket 1 in the second direction y.

[0030] The bracket 1 is designed for fixing to the submersible pump's riser flange 5, and its mounting hole 11 is sized to match the bolt 6 size used on the riser flange 5. The through hole 3 is suitable for various pipelines 7, including cables 71 and dosing pipes 72. The through hole 3, formed by the fastener 2 and the bracket 1, for fixing the pipeline 7, can confine the pipeline 7 to a preset position, effectively preventing it from shaking, displacing, and whiplashing during operation.

[0031] In some improvements of this application, the bracket 1 has at least two mounting holes 11, which are arranged alternately. The bracket 1 has a clearance groove 12 on its edge away from the fixing member 2 in the second direction y. The clearance groove 12 is located between two adjacent mounting holes 11 and extends through the first direction x. Multiple mounting holes 11 are arranged alternately along the circumference of the water supply pipe flange 5, and the distance between two adjacent mounting holes 11 is the same as the distance between the bolt holes of the water supply pipe flange 5. The clearance groove 12 is used to avoid the reinforcing ribs 512 on the water supply pipe or flange. Specifically, the projection of the clearance groove 12 in the first direction x is U-shaped.

[0032] In some improvements of this application, the bracket 1 includes a first plate 13 and a second plate 14 connected to each other. The first plate 13 has two sides opposite to each other along the first direction x, and the second plate 14 has two sides opposite to each other along the second direction y. The mounting hole 11 is formed in the first plate 13, and the second plate 14 is located at the edge of the first plate 13 in the second direction y. The through hole 3 is formed between the second plate 14 and the fixing member 2. Specifically, the first plate 13 and the second plate 14 form a 90° or approximately 90° angle, which enhances the structural strength and rigidity of the bracket 1 itself and ensures the overall stability of the fixing device. The first plate 13 is used to fit and connect with the water supply pipe flange 5. The clearance groove 12 is formed on the side edge of the first plate 13 facing away from the second plate 14 in the second direction y. The second plate 14 is used to fix the fixing member 2, providing a solid and reliable connection base for the fixing member 2.

[0033] In some improvements of this application, the projection of the fixing member 2 in the first direction x is U-shaped, and both ends of the fixing member 2 are respectively connected to the second plate 14 to enclose and form the through hole 3. The U-shaped fixing member 2 enables it to provide an arc-shaped surrounding structure for the pipeline 7. When both ends of the fixing member 2 are connected to the second plate 14, they together with the second plate 14 enclose and form a closed through hole 3 that can completely enclose the pipeline 7, which facilitates the installation and fixing of the pipeline 7.

[0034] In some improvements of this application, the second plate 14 has at least two connecting holes 141, and the two ends of the fixing member 2 are detachably connected to the second plate 14 through the two connecting holes 141 respectively. When the pipeline 7 needs to be replaced or inspected, it is not necessary to remove the entire fixing device from the water supply pipe flange 5. It is only necessary to disconnect the detachable connection between the fixing member 2 and the second plate 14 to easily remove or insert the pipeline 7, thereby reducing the difficulty and cost of equipment maintenance.

[0035] In some improvements of this application, at least two nuts 4 are also included. Both ends of the fastener 2 are threaded, and both ends of the fastener 2 pass through the two connecting holes 141 and are connected to the two nuts 4 in a one-to-one correspondence. Specifically, the connecting hole 141 can be elongated to accommodate U-shaped fasteners 2 of different sizes, thus being suitable for pipelines 7 of various diameters, and tailored to pipelines 7 of different thicknesses to ensure that they do not shift or shake.

[0036] Reference Figure 1 This application also provides a submersible pump, including a water supply pipe flange 5, a pipeline 7 and the aforementioned submersible pump pipeline 7 fixing device. The bracket 1 is connected to the water supply pipe through the mounting hole 11, and the pipeline 7 passes through the through hole 3 and is connected to the bracket 1.

[0037] The motor of a submersible pump is typically located at the bottom of the pump and provides power. The pump body is connected above the motor and is used to lift fluid from the well. The riser pipe is a piping system connecting the pump body to the surface pipeline. It consists of multiple sections of pipe connected section by section via riser pipe flanges 5 (e.g., round or square flanges), forming a vertical upward fluid transport channel that simultaneously supports the weight of the pump and underwater components. This structure makes lowering and removing the submersible pump for maintenance and installation quicker and easier, eliminating the need to drill holes in the pump components. Installation is flexible, and the pipeline 7 is securely fixed.

[0038] In some improvements to this application, bolts 6 are also included. The water supply pipe flange 5 includes a first flange 51 and a second flange 52. The first flange 51 has a first bolt hole 511, and the second flange 52 has a second bolt hole 521. The bolts 6 pass sequentially through the mounting hole 11, the first bolt hole 511, and the second bolt hole 521 to connect the bracket 1, the first flange 51, and the second flange 52. By utilizing the existing bolt 6 connection channels between the water supply pipe flanges 5, the bracket 1 of the pipeline 7 fixing device is integrated into the structural connection system of the water supply pipe. There is no need to drill additional holes or make complex modifications to the water supply pipe flange 5 or the water supply pipe body, achieving seamless integration of the fixing device and the water supply pipe system, saving space to the maximum extent, and maintaining the integrity of the water supply pipe system.

[0039] In some improvements of this application, the first flange 51 has a reinforcing rib 512 protruding from the side opposite to the second flange 52 along the first direction x, and part of the reinforcing rib 512 is disposed within the clearance groove 12. By opening the clearance groove 12 on the bracket 1, the bracket 1 can be precisely and tightly fitted onto the flange with the reinforcing rib 512, avoiding interference of the reinforcing rib 512 with the installation of the bracket 1 and ensuring the flexibility of the bracket 1 installation.

[0040] In some improvements of this application, at least two of the submersible pump pipeline 7 fixing devices are included. The pipeline 7 includes a dosing pipe 72 and a cable 71. The dosing pipe 72 passes through the through hole 3 of one of the submersible pump pipeline 7 fixing devices, and the cable 71 passes through the through hole 3 of the other submersible pump pipeline 7 fixing device.

[0041] In summary, this utility model embodiment provides a submersible pump pipeline fixing device and its submersible pump. By cleverly designing the bracket 1 to share the existing bolt 6 connection point with the riser pipe flange 5, it eliminates the need for additional drilling on the riser pipe, greatly simplifying the installation process and making the pump lowering and lowering for maintenance and installation more flexible, quick, and convenient. The device utilizes the through hole 3 formed by the bracket 1 and the fixing component 2 to tightly and reliably constrain the cable 71 or dosing pipe 72, completely avoiding problems such as unfixed sagging and swaying of the pipeline 7. This stable fixing method eliminates the damage to the submersible motor sealing interface caused by pipeline 7 swaying at its source, preventing such damage and significantly improving the equipment's operational stability and reliability. It effectively reduces maintenance costs and unplanned downtime, comprehensively improving the safety and efficiency of deep well operations.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
