Description

Technical Field

[0001] This utility model relates to the technical field of rigid suspension equipment, specifically a rigid suspension device suitable for the protection of submersible axial flow pump cables. Background Technology

[0002] A submersible axial flow pump is a water pump device that combines a pump and a motor. It is typically used in applications requiring high flow rates and low head, and is widely used in farmland irrigation, urban drainage, and industrial circulating water systems. The working principle of a submersible axial flow pump is based on axial flow design, with the water flow direction parallel to the pump shaft. The rotating impeller propels the water along the axial direction. The pump body is completely submerged in water, and the motor is waterproofed through a sealing device, ensuring normal operation underwater.

[0003] Submersible axial flow pump cables are cables specifically designed for submersible axial flow pumps, often referred to as submersible pump-specific cables. These cables are waterproof, corrosion-resistant, and high-pressure resistant, enabling them to safely and stably transmit electrical energy in underwater environments. However, they are typically equipped with suspension devices during use. During suspension, the cables are prone to being pulled or twisted, which can easily cause unnecessary damage. Therefore, in light of the above situation, there is an urgent need to develop a rigid suspension device suitable for the protection of submersible axial flow pump cables to overcome the shortcomings in current practical applications. Utility Model Content

[0004] The purpose of this invention is to provide a rigid suspension device suitable for the protection of cables in submersible axial flow pumps, in order to solve the problem mentioned in the background art that cables are easily pulled or twisted during the suspension process, which can easily cause unnecessary damage to the cables.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rigid suspension device for protecting the cable of a submersible axial flow pump includes a steel pipe and a steel cover, wherein the steel pipe and the steel cover are fixedly connected by a second connecting flange;

[0007] A bearing ring plate is fixed on the inner wall of the steel pipe, a second limiting block is fixed on the top of the bearing ring plate, a fixing flange is fixed at the middle position of the top of the bearing ring plate, and a first limiting block is fixed on the outer wall of the fixing flange.

[0008] The first limiting block and the second limiting block cooperate to form a limiting structure, which is used to restrict the rotation of the cable.

[0009] As a further embodiment of this utility model: the second limiting block is distributed in a ring around the center of the steel pipe, and the first limiting block is distributed in a ring around the center of the fixed flange.

[0010] As a further embodiment of this utility model: the first limiting block is provided with a limiting groove, and the second limiting block is fixed with a protrusion;

[0011] The limiting groove is concave, and the protrusion is adapted to the limiting groove.

[0012] As a further embodiment of this utility model: a first connecting flange is fixed to the top of the steel pipe, and an outlet pipe is fixed to the top of the first connecting flange.

[0013] As a further embodiment of this utility model: a cable protection assembly is passed through the outlet pipe and the fixed flange, and the cable protection assembly includes a power cable and a control cable.

[0014] As a further embodiment of this utility model: the power cable and the control cable are wrapped with rubber protective sheaths, and the two are tightly attached to each other.

[0015] As a further embodiment of this utility model: the second connecting flange is equipped with connecting bolts for connection and fixation, and the plurality of connecting bolts are distributed in a ring about the center of the second connecting flange.

[0016] As a further embodiment of this utility model, hanging rings are welded to both sides of the steel pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. First, fix the bearing ring plate to the inner wall of the steel pipe, and fix the fixing flange at the middle position of the bearing ring plate. The hollow position in the middle of the fixing flange can be used for the cable protection component to pass through. Then, fix the first limiting block on the outer wall of the fixing flange, and the first limiting block has a limiting groove. Fix the second limiting block on the bearing ring plate, and fix the protrusion on the second limiting block. Therefore, the protrusion can be locked in the inside of the limiting groove for limiting. One first limiting block and one second limiting block match and correspond, and the left and right positions of one set of first limiting blocks and second limiting blocks can be opposite. Therefore, under the limiting treatment, the rotation of the cable protection component can be effectively prevented, and the overall anti-rotation capability is improved.

[0019] 2. When using power cables and control cables, the power cables and control cables are placed inside steel pipes, with the outer edges of the cables wrapped in rubber protective sheaths and secured with self-adhesive tape. This protects the outer surface of the power cables and control cables, reducing the risk of cable damage. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1-3 This utility model provides a rigid suspension device for protecting the cable of a submersible axial flow pump, comprising a steel pipe 4 and a steel cover 5. A second connecting flange 6 is fixed between the steel pipe 4 and the steel cover 5 for connection. The second connecting flange 6 is equipped with connecting bolts 7 for connection and fixation. A bearing ring plate 11 is fixed on the inner wall of the steel pipe 4. A second limiting block 16 is fixed on the top of the bearing ring plate 11. A fixing flange 12 is fixed at the middle position of the top of the bearing ring plate 11. A first limiting block 14 is fixed on the outer wall of the fixing flange 12.

[0027] In one embodiment of this utility model, the second limiting block 16 is distributed in a ring around the center of the steel pipe 4, and the first limiting block 14 is distributed in a ring around the center of the fixed flange 12.

[0028] A limiting groove 13 is formed in the first limiting block 14, and a protrusion 15 is fixed in the second limiting block 16.

[0029] The limiting groove 13 is concave, and the protrusion 15 is adapted to the limiting groove 13.

[0030] In one embodiment of this utility model, the connecting bolts 7 are arranged in a ring about the center of the second connecting flange 6, the top of the steel pipe 4 is fixed with the first connecting flange 3, and the top of the first connecting flange 3 is fixed with the outlet pipe 1.

[0031] Cable protection assembly 2 passes through both the outlet pipe 1 and the fixed flange 12. The cable protection assembly 2 includes a power cable 9 and a control cable 10.

[0032] The power cable 9 and the control cable 10 are wrapped with rubber protective sheath 8, and the power cable 9 and the control cable 10 are tightly attached to each other.

[0033] In one embodiment of this utility model, hanging rings 17 are fixed on both sides of the steel pipe 4, and the steel pipe 4 and the hanging rings 17 are welded and fixed together.

[0034] When used in conjunction with the ear loop 4 for suspension work, this part can be used with cables to suspend the submersible axial flow pump during use and lifting, which can protect the cable and solve the problem of the cable being easily pulled or twisted during suspension, solve the problem of cable wear and damage, and overcome the defects of easy cable wear, poor sealing or difficult installation and maintenance.

[0035] Therefore, the working process of this utility model for the rigid suspension equipment for the protection of submersible axial flow pump cables is to first install the submersible axial flow pump, and then allow the cable to pass through the assembly.

[0036] Working principle: First, when power cable 9 and control cable 10 are used, they are located inside the anti-lifting steel pipe. The cables are wrapped with rubber protective sheath 8 and secured with self-adhesive tape and cable ties. This protects the outer surface of power cable 9 and control cable 10. The bearing ring plate 11 is fixed to the inner wall of the steel pipe 4. After fixing the fixing flange 12 at the middle position inside the bearing ring plate 11, the hollow position in the middle of the fixing flange 12 can be used for the cable protection assembly 2 to pass through. Then, a first limiting block 14 is fixed on the outer wall of the fixed flange 12, and a limiting groove 13 is opened in the first limiting block 14. A second limiting block 16 is fixed on the bearing ring plate 11, and a protrusion 15 is fixed on the second limiting block 16. Therefore, the protrusion 15 can be locked inside the limiting groove 13 for limiting. One first limiting block 14 and one second limiting block 16 are matched and correspond to each other, so that the left and right positions of one set of first limiting blocks 14 and second limiting blocks 16 are opposite, which is used to prevent the cable protection assembly 2 from rotating and other phenomena.
