[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] First of all, it should be noted that if the cable is soaked in water for a long time, the copper core of the cable may be corroded and impurities may be generated, such as verdigris (the main component is Cu(OH)2·CuCO3) attached to the surface of the copper core, affecting the conductive properties of the copper core.

[0036] It should be further explained that, since the copper core of the cable is wrapped by a surface layer, generally speaking, the end of the cable is most likely to be immersed in water and produce verdigris attached to the surface of the copper core. Therefore, the cable copper core processing device of the utility model is mainly used to process the copper core at the end of the cable.

[0037] like Figure 1 , Figure 3 As shown, the utility model provides a cable copper core processing device, which includes a reducing agent container 100, a connecting pipe assembly 200 and a heating element 300.

[0038] Combination Figure 1 , Figure 3 and Figure 4The reducing agent container 100 is used to contain the reducing agent. The inlet end of the connecting tube assembly 200 is connected to the reducing agent container 100, the outlet end of the connecting tube assembly 200 is made of elastic material, and the inner diameter of the outlet end of the connecting tube assembly 200 gradually increases along the outflow direction of the reducing agent in the connecting tube assembly 200, and the outlet end of the connecting tube assembly 200 is used for the end to be treated of the cable 10 to extend into; the heating element 300 is used to heat the end to be treated of the cable 10.

[0039] It should be noted that copper core 11 in the treated end of cable 10 is attached with verdigris (mainly composed of Cu(OH)2·CuCO3), and heating element 300 can heat the treated end of cable 10, so that Cu(OH)2·CuCO3 is converted into CuO, H2O and CO2; the reducing agent is used to reduce CuO to convert CuO into Cu, wherein the reducing agent can be H2 or CO. Specifically, when heated, CuO+H2=Cu+H2O; when heated, CuO+CO=Cu+CO2.

[0040] When the cable copper core processing device of the utility model is used, the end to be processed of the cable 10 can be first inserted into the outlet end of the connecting tube assembly 200. Since the outlet end of the connecting tube assembly 200 is made of elastic material and gradually increases along the outflow direction of the reducing agent in the connecting tube assembly 200, it is suitable for the insertion of cables 10 of different diameters. The insertion of the cable 10 with a small diameter is longer, and the insertion of the cable 10 with a large diameter is shorter. After the end to be processed of the cable 10 is inserted into the outlet end of the connecting tube assembly 200, the heating element 300 is first used to heat the end to be processed of the cable 10, so that Cu(OH)2·CuCO3 is converted into CuO, H2O and CO2; then, while heating the end to be processed of the cable 10, the reducing agent in the reducing agent container 100 is passed through the connecting tube assembly 200 to the end to be processed of the cable 10, so that the reducing agent reacts with CuO, so that CuO is converted into Cu. In this way, the cable copper core processing device of the present invention can remove the Cu(OH) 2 ·CuCO 3 on the surface of the copper core 11 of the cable 10 , thereby restoring the conductive performance of the cable 10 .

[0041] It should be noted that the end to be processed of the cable 10 does not only refer to the port part of the end to be processed of the cable 10. The cable 10 within a certain range from the port of the end to be processed still belongs to the end to be processed of the cable 10. The length of this part can be within 50 cm.

[0042] like Figure 3 , Figure 6 As shown, further, the heating element 300 is sleeved on the outside of the cable 10 to heat the end to be processed of the cable 10 .

[0043] It is understandable that, after the end to be processed of the cable 10 is inserted into the outlet end of the connecting tube assembly 200, a portion of the end to be processed of the cable 10 will still be left outside the connecting tube assembly 200. The heating element 300 can be sleeved on the outside of the cable 10 outside the connecting tube assembly 200 and heat the cable 10. Since heat can be transferred, the heat generated by the heating element 300 can be transferred to the entire end to be processed of the cable 10. In addition, by sleeved on the outside of the cable 10, the cable 10 can be heated more evenly, thereby ensuring the treatment effect.

[0044] It should be noted that the heating element 300 may be in the form of a heating blanket. The heating element 300 may be unfolded, or the heating element 300 may be rolled up and sleeved on the outside of the cable 10 .

[0045] In some embodiments, the cable copper core processing device further includes a clamp, which is used to be sleeved on the outlet end of the connecting tube assembly 200 and clamp the end to be processed of the cable 10. In this way, a reliable connection between the connecting tube assembly 200 and the cable 10 can be achieved, reducing the risk of the cable 10 coming out of the connecting tube assembly 200.

[0046] It should be noted that, precisely because the outlet end of the connecting pipe assembly 200 is made of elastic material, a clamp can be used to connect the connecting pipe assembly 200 and the cable 10. The clamp is convenient and quick to use and is also easy to disassemble.

[0047] Combination Figure 3 and Figure 4 In some embodiments, a narrow tube 600 is disposed inside the outlet end of the connecting tube assembly 200 . When the end of the cable 10 to be processed is inserted into the outlet end of the connecting tube assembly 200 , the end of the cable 10 to be processed is disposed opposite to the narrow tube 600 .

[0048] It should be noted that the narrow tube 600 can utilize the narrow tube effect. When the reducing agent in the connecting tube assembly 200 passes through the narrow tube 600, the pressure and flow rate of the reducing agent are increased under the narrow tube effect, so that the reducing agent penetrates into the copper core 11 with greater force, thereby achieving the purpose of reducing CuO at a deeper level and improving the treatment effect.

[0049] Combination Figure 4 and Figure 5 Specifically, the narrow tube 600 includes a connecting portion 610 and a plurality of capillaries 620. The connecting portion 610 is provided with a plurality of through holes. One end of each capillary 620 is connected to the connecting portion 610. The plurality of capillaries 620 are arranged in parallel, and the plurality of capillaries 620 are arranged one by one opposite to the plurality of through holes. The connecting portion 610 is connected to the inner wall of the connecting tube assembly 200, and the outlet end of the capillary 620 faces the outlet of the connecting tube assembly 200.

[0050] It should be noted that the connecting portion 610 is circular; each through hole passes through both sides of the connecting portion 610; one end of each capillary 620 is connected to the connecting portion 610, and the axis of each capillary 620 is parallel to the axis of the connecting portion 610, wherein multiple capillaries 620 are arranged one by one opposite to multiple through holes, so that each capillary 620 is connected to each through hole respectively.

[0051] It is understandable that the connecting portion 610 and the capillary 620 may be integrated, or may be independently manufactured and assembled together.

[0052] The narrow tube 600 is arranged inside the outlet end of the connecting tube assembly 200, wherein the connecting portion 610 is connected to the inner wall of the connecting tube assembly 200, and the outlet end of the capillary tube 620 is directed toward the outlet of the connecting tube assembly 200, that is, the end of the capillary tube 620 away from the connecting portion 610 is directed toward the outlet of the connecting tube assembly 200. When the reducing agent in the connecting tube assembly 200 passes through the narrow tube 600, the reducing agent will be divided into a plurality of capillaries 620 to generate a narrow tube effect, under which the pressure and flow rate of the reducing agent are increased, so that the reducing agent penetrates into the copper core 11 with greater force, thereby achieving the purpose of reducing CuO at a deeper level and improving the treatment effect.

[0053] It should be noted that the inner diameter of the capillary 620 can be set between 0.5 mm and 5 mm.

[0054] It can be understood that the copper core 11 of some cables 10 is formed by rolling together multiple strands of copper core 11. For such cables 10, after the end to be treated of the cable 10 is inserted into the outlet end of the connecting tube assembly 200, the capillary 620 can be inserted into the copper core 11 of the cable 10. Under the action of the narrow tube effect, the reducing agent can further penetrate into the interior of the copper core 11 with greater force.

[0055] It should be noted that the connecting portion 610 is snap-fitted to the inner wall of the connecting pipe assembly 200 .

[0056] It is understandable that, because the outlet end of the connecting tube assembly 200 is made of elastic material, the outlet end of the connecting tube assembly 200 can support and seal the connecting portion 610 , thereby achieving the positioning of the connecting portion 610 .

[0057] Combination Figure 1 and Figure 2 In some embodiments, a valve 400 is provided on the connecting pipe assembly 200 , and the valve 400 is used to control the on-off of the entire connecting pipe assembly 200 .

[0058] It is understandable that when the cable copper core processing device is not working, or when the reducing agent is not needed, the valve 400 is in a closed state, which can reduce the risk of reducing agent leakage.

[0059] Furthermore, the cable copper core processing device also includes a controller, and the valve 400 and the heating element 300 are electrically connected to the controller, and the controller is used to control the start and stop of the valve 400 and the heating element 300.

[0060] It is understandable that the valve 400 is an electrically controlled valve, which is started and stopped by the controller; the heating element 300 is an electrically controlled heating element, which can also be started and stopped by the controller. In this way, the operation can be convenient.

[0061] It should be noted that, for the reducing agent container 100, a stop valve is provided at its outlet, and the inlet end of the connecting pipe assembly 200 is connected to the stop valve. When the stop valve is opened, the controller controls the action of the valve 400 to determine whether the reducing agent is used in the work.

[0062] It is understandable that for high-density and high-pressure gas-type reducing agents, when the shut-off valve and the valve 400 are opened, these gases will directly pass through the connecting pipe assembly 200 and react with the CuO on the surface of the copper core 11 .

[0063] In some embodiments, the reducing agent may be carbon powder or other powdered reducing agents. A pump body is provided at the outlet of the reducing agent container 100 , and the pump body may draw the carbon powder into the connecting pipe assembly 200 to allow the carbon powder to react with CuO on the surface of the copper core 11 .

[0064] Furthermore, a sensor 500 is provided on the connecting pipe assembly 200 , and the sensor 500 is used to detect at least one parameter of the gas composition, air pressure, humidity and temperature in the connecting pipe assembly 200 .

[0065] It should be noted that the connecting pipe assembly 200 includes a first connecting pipe 210, a second connecting pipe 220, a first intermediate connecting pipe 230 and a second intermediate connecting pipe 240. One end of the first connecting pipe 210 is connected to the reductant container 100, and the other end is connected to the first intermediate connecting pipe 230. The back of the first intermediate connecting pipe 230 is connected to the valve 400, the back of the valve 400 is connected to the sensor 500, the back of the sensor 500 is connected to the second intermediate connecting pipe 240, and the back of the second intermediate connecting pipe 240 is connected to the second connecting pipe 220.

[0066] It can be understood that the outlet end of the second connecting pipe 220 is the outlet end of the connecting pipe assembly 200 , and the second connecting pipe 220 is made of elastic material, that is, the outlet end of the second connecting pipe 220 is an elastic material.

[0067] The elastic material may be rubber.

[0068] It should be noted that the sensor 500 is also electrically connected to the controller. The sensor 500 can simultaneously detect the air pressure, humidity and temperature in the connecting pipe assembly 200, thereby facilitating the controller to control the operation of the valve 400 and the heating element 300.

[0069] When the cable copper core processing device of the utility model is used, the end to be processed of the cable 10 can be first inserted into the outlet end of the connecting tube assembly 200. Since the outlet end of the connecting tube assembly 200 is made of elastic material and gradually increases along the outflow direction of the reducing agent in the connecting tube assembly 200, it is suitable for the insertion of cables 10 of different diameters. The insertion of the cable 10 with a small diameter is longer, and the insertion of the cable 10 with a large diameter is shorter. After the end to be processed of the cable 10 is inserted into the outlet end of the connecting tube assembly 200, the heating element 300 is first used to heat the end to be processed of the cable 10, so that Cu(OH)2·CuCO3 is converted into CuO, H2O and CO2; then, while heating the end to be processed of the cable 10, the reducing agent in the reducing agent container 100 is passed through the connecting tube assembly 200 to the end to be processed of the cable 10, so that the reducing agent reacts with CuO, so that CuO is converted into Cu. In this way, the cable copper core treatment device of the utility model can remove the Cu(OH)2·CuCO3 on the surface of the copper core 11 of the cable 10, thereby restoring the electrical conductivity of the cable 10. In addition, the narrow tube 600 can utilize the narrow tube effect. When the reducing agent in the connecting tube assembly 200 passes through the narrow tube 600, the pressure and flow rate of the reducing agent are increased under the narrow tube effect, so that the reducing agent penetrates deeper into the copper core 11 with greater force, thereby achieving the purpose of reducing CuO in a deeper layer and improving the treatment effect.
