Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and in particular relates to a submersible pump cable. Background Technology

[0002] Submersible pumps are important equipment for lifting water from deep wells and other bodies of water. The entire unit operates submerged in water, extracting groundwater or other water from other bodies of water to the surface. They are convenient to use and inexpensive. The submersible pump cable is an important component that connects the submersible pump to the power source. It is used to transmit electrical energy and has good waterproof, insulation and wear resistance properties.

[0003] Currently, in practical applications, it has been found that the surface of existing submersible pump cables is prone to aging when submerged in water for extended periods, affecting normal operating performance. Furthermore, subsequent maintenance requires the use of lifting equipment to remove the cables, which makes maintenance work difficult, affects efficiency, and takes too long, potentially disrupting the normal operation of water pumping.

[0004] To address the aforementioned problems, this application proposes a submersible pump cable. Utility Model Content

[0005] The purpose of this invention is to provide a submersible pump cable that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a submersible pump cable, comprising: a cable; a protective sleeve fitted over the outside of the cable, wherein the outer side of the protective sleeve is provided with an inflatable band, which, when slightly inflated, causes the surfaces of adjacent inflatable bands to abut against each other, thereby reducing the contact between the cable and water and delaying aging; and an inner air band, which is segmented and distributed inside the protective sleeve, with a spacer between adjacent inner air bands for transferring gas. When gas is filled in, the inner air band expands outward, exerting pressure on the cable and increasing frictional resistance, thereby achieving the effect of convenient assembly and disassembly.

[0008] Furthermore, the end of the cable is connected to the connector of the submersible pump, and a sealing box is provided on the outside of the connection to form a waterproof seal.

[0009] Furthermore, the protective sleeve has pull ropes distributed circumferentially inside to enhance its tensile strength.

[0010] Furthermore, an adapter is provided on the outer side of one end of the protective sleeve, through which a rope is installed to connect to the lifting lug of the submersible pump.

[0011] Furthermore, the protective sleeve has a first inflation port at the upper right end that is connected to the inflation belt, and a second inflation port that is connected to the inner air belt.

[0012] Furthermore, the interior of the inflatable belt is provided with a through groove, and a connecting pipe is provided between adjacent inflatable belts to connect adjacent inflatable belts for gas transmission.

[0013] Furthermore, after the inflatable belt applies buoyancy, the protective sleeve and pull rope replace the lifting equipment to bring the submersible pump to land, which is convenient for emergency maintenance operations.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, by adding a protective sleeve, allows adjacent air-filled bands to come into contact with each other during use, thereby reducing the contact between external water and the cable and slowing down the aging of the cable. At the same time, the air-filled bands can expand by inflation, making it easy to install the protective sleeve. The support is simple and convenient for subsequent maintenance and other handling.

[0016] This utility model, through the cooperation of the adapter, binding rope, and pull rope, allows the protective sleeve to replace the cable in bearing the tension. Furthermore, by continuously inflating the air belt, the cable expands, which greatly increases the buoyancy, making it easy for the submersible pump to be manually pulled out for inspection and maintenance. This enhances the practicality of the cable, simplifies maintenance operations, improves work efficiency, and facilitates the normal operation of water lifting.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-4 As shown, this utility model is a submersible pump cable, including: cable 1;

[0028] The protective sleeve 4 is fitted on the outside of the cable 1. The outer side of the protective sleeve 4 is provided with an air-filled band 5. After slight inflation, the surfaces of adjacent air-filled bands 5 come into contact with each other to reduce the contact between the cable 1 and water and delay aging. After continuous inflation, the air-filled bands 5 expand outward to increase buoyancy, which reduces the difficulty of lifting the submersible pump and facilitates manual operation. Pull ropes 8 are distributed circumferentially inside the protective sleeve 4 to enhance the tensile strength of the protective sleeve 4.

[0029] The inner air belt 9 is distributed in segments inside the protective sleeve 4. A spacer 10 is provided between adjacent inner air belts 9 to transfer gas. After being filled with gas, the inner air belt 9 expands outward to compress the cable 1 and increase the frictional resistance, so as to achieve the effect of easy disassembly and assembly.

[0030] The end of cable 1 is connected to the connector 2 of the submersible pump, and a sealing box 3 is provided on the outside of the connection to form a waterproof seal;

[0031] This embodiment provides a cable structure that facilitates maintenance. By utilizing the protective sleeve 4 with a built-in pull rope 8 and the inflatable belt 5 in an inflated state, the buoyancy can be greatly increased, allowing the submersible pump to be manually pulled up, which is convenient for maintenance and repair of the cable 1 and the submersible pump. In addition, by adjusting the squeezing pressure and frictional resistance by inflating the internal air belt 9, the protective sleeve 4 can be easily disassembled and assembled. The structure is simple, convenient for installation and use, and improves the practical performance of the cable.

[0032] The protective sleeve 4 has an adapter 6 on one side. By attaching a rope 7 to the outside of the adapter and connecting it to the lifting lug of the submersible pump, the protective sleeve 4 and the pull rope 8 replace the lifting equipment to lift the submersible pump to land after the air belt 5 applies buoyancy, which facilitates emergency maintenance operations.

[0033] The protective sleeve 4 has a first inflation port 11 at the upper right end that is connected to the inflation belt 5, and a second inflation port 12 that is connected to the inner air belt 9. The lengths of the protective sleeve 4 and the inflation belt 5 are determined according to the installation position of the submersible pump.

[0034] The air-filled belt 5 has a through groove 13 inside, and a connecting pipe 14 is provided between adjacent air-filled belts 5. The adjacent air-filled belts 5 are connected through the through groove 13 to transmit gas, so that each air-filled belt 5 has the same inflation state.

[0035] Understandably, this utility model can conveniently lift the cable and submersible pump to land, facilitating their inspection and maintenance. Furthermore, by increasing buoyancy, the submersible pump can be manually pulled without lifting the equipment, reducing work difficulty and improving efficiency, while also being convenient for temporary emergency repairs.

[0036] A specific application of the operation process in this embodiment is as follows: Before the cable 1 is put into use, the protective sleeve 4 is placed on the outside of the cable 1 according to the predetermined length. Then, the inner air belt 9 is inflated through the second air inlet 12 to make it expand. This creates compression and friction to fix the protective sleeve 4 to the outside of the cable 1. At this time, the submersible pump connector 2 is connected to the cable 1 and tied to the lifting lug of the submersible pump by the binding rope 7. After this arrangement, it can be put into use. During use, the air belt 5 is inflated through the first air inlet 11 to make it expand. The adjacent air belts 5 abut against each other to reduce the contact between the cable and water, thereby delaying aging. When it is necessary to remove it for maintenance after a period of use, the air belt 5 is inflated again to make it continue to expand, thereby greatly increasing the buoyancy. In conjunction with the pull rope 8, the stability is enhanced. The submersible pump can be pulled out by the protective sleeve 4. The submersible pump can be easily removed manually without the need for lifting equipment. This facilitates maintenance work, reduces the difficulty of operation, improves efficiency, and makes it easy to restore the submersible pump to normal operation in a short time.
