Description

Technical Field

[0001] This utility model belongs to the technical field of cable coating, and in particular relates to a cable silicone grease coating device. Background Technology

[0002] Electric wires and cables are indispensable infrastructure in modern society, primarily used for transmitting electrical energy and signals. High-voltage cables refer to cables with a rated voltage greater than 35kV, mainly used for power grid transmission. In actual production, taking a 10kV high-voltage cold-shrink cable termination as an example, the material of the cold-shrink cable termination is made of silicone rubber. After the internal support is removed, each cold-shrink tube automatically shrinks, tightly locking the cable. The amount of silicone grease required for each cable termination is shown in the detailed diagram in the installation instructions for each cable termination.

[0003] However, in related technologies, silicone grease is usually applied manually. Manual application can easily lead to excessive application of the grease to the cable termination. A large amount of grease begins to age, gradually hardening into a solid mass. When this irregular liquid solidifies, gaps will appear in the 10kV cable termination, making it prone to partial discharge and reducing the overall insulation level of the cable termination. Therefore, during cable termination installation, the amount of silicone grease applied must be appropriate. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In related technologies, silicone grease is usually applied to cables manually. However, manual application can easily lead to excessive application of silicone grease to the cable termination. As a large amount of grease ages and hardens into a solid, gaps will appear in the 10kV cable termination, increasing the risk of partial discharge and reducing the overall insulation level of the termination. Therefore, the amount of silicone grease applied during cable termination installation must be appropriate.

[0034] To address the aforementioned technical problems, this utility model proposes a cable silicone grease coating device 100.

[0035] As attached Figure 1 The diagram shown is a schematic representation of the overall structure of the cable silicone grease coating device 100 in an embodiment of this utility model; as shown in the attached diagram. Figure 2 The diagram shown is a structural schematic of the cable 200 being coated by the cable silicone grease coating device 100 in an embodiment of this utility model; as shown in the attached diagram. Figure 3 The diagram shown is a cross-sectional view of the cable during the application of silicone grease to the cable in the cable grease coating device 100, as illustrated in the attached figure. Figure 4 The diagram shown is a schematic representation of the assembly structure of the cable silicone grease coating device 100 in an embodiment of this utility model; as shown in the attached diagram. Figure 5-7 The image shown is a cross-sectional view of the cable silicone grease coating device 100 in an embodiment of this utility model. (See attached image.) Figure 1-7 It is known that the cable silicone grease coating device 100 includes a coating part 1, a loading part 2, and a pressing component 3.

[0036] The coating section 1 has a circular slot 11, and a guide groove 12 is provided on the inner side of the circular slot 11. The circular slot 11 is adapted to the shape of the cable 200 so that the cable 200 can pass through the circular slot 11 and be coated within the circular slot 11. When the cable 200 is located within the circular slot 11, the coating material flows out through the guide groove 12 and is coated onto the cable 200. For example, the guide groove 12 is arranged around the inner circumference of the circular slot 11, so that the cable 200 can be coated with coating material all around. The coating material is preferably silicone grease.

[0037] The loading section 2 is provided with a connected loading cavity 21 and two guide pipes 22. The two guide pipes 22 are respectively located on both sides of the loading cavity 21 and are connected to the guide groove 12. The loading cavity 21 is used to store coating material, which is a fluid. The coating material in the loading cavity 21 can be guided to the guide groove 12 through the guide pipes 22. The two guide pipes 22 guide the coating material to two positions in the coating section 1, allowing the coating material to flow quickly within the coating section 1 and be evenly coated onto the cable 200 through the guide groove 12.

[0038] The pressing component 3 is movably disposed in the loading chamber 21. Relative to the loading chamber 21, the pressing component 3 is movable and can squeeze the coating material within the loading chamber 21 into the guide pipe 22. When the pressing component 3 moves closer to the loading chamber 21, it squeezes the coating material within the loading chamber 21, causing the coating material to flow along the guide pipe 22. Each time the pressing component 3 is pressed, the amount of coating material squeezed into the guide pipe 22 is fixed, thereby controlling the amount of coating material applied to the cable 200, avoiding excessive coating material on the cable 200, and preventing waste of coating material.

[0039] As can be seen from the above embodiments, when the cable silicone grease coating device 100 of this utility model coats the cable 200, it controls the amount of coating material by pressing component 3, so as to avoid excessive coating material on the cable 200 and to avoid waste of coating material.

[0040] For example, the operator can manually control the pressing component 3 to adjust the coating amount, precisely controlling the coating range of the silicone grease, ensuring the insulation of the cable 200 and preventing aging problems caused by over-coating. In addition, the pressing component 3 can be removed from the loading cavity 21 for cleaning. The cable silicone grease coating device 100 has a simple structure, and cleaning can be completed through a simple cleaning process, ensuring that the cable silicone grease coating device 100 remains clean after each use, preventing silicone grease residue from affecting the next use.

[0041] As attached Figure 2-5As shown, in some embodiments, the pressing assembly 3 includes a pressing part 31 and an elastic member 32. The pressing part 31 has a cavity 311 that communicates with the loading cavity 21. One end of the elastic member 32 abuts against the top of the inner wall of the cavity 311, and the other end abuts against the bottom of the loading cavity 21. Pressing the pressing part 31 compresses the coating material in the cavity 311 and the loading cavity 21, causing the coating material to flow into the guide pipe 22. At this time, the elastic member 32 is in a compressed state. After pressing the pressing part 31, releasing the pressing part 31 causes the elastic member 32 to unfold under the action of elastic force, thereby restoring the pressing part 31 to its original position for the next pressing. For example, one end of the elastic member 32 is fixedly connected to the top of the inner wall of the cavity 311, and the other end is fixedly connected to the bottom of the loading cavity 21. The elastic element 32 is a spring, and the pressing part 31 is provided with a limiting post (not shown in the figure). The elastic element 32 is fitted inside the limiting post. The limiting post can restrict the compression direction and unfolding direction of the elastic element 32, preventing the elastic element 32 from bending under the action of force. The compression direction and unfolding direction of the elastic element 32 are parallel to the direction of the pressing part 31 near the loading cavity 21.

[0042] As attached Figure 3-4 As shown, in some embodiments, the pressing part 31 has an abutment part 312 on its periphery, which abuts against the peripheral wall of the loading cavity 21. The pressing part 31 moves within the loading cavity 21, increasing the air pressure in the cavity 311 and the loading cavity 21 by pressing, thereby squeezing out the coating material. The connection between the pressing part 31 and the loading cavity 21 needs to be sealed. The abutment part 312 abuts against the peripheral wall of the loading cavity 21, ensuring that the loading cavity 21 and the cavity 311 remain sealed. This allows the coating material in the loading cavity 21 to be effectively squeezed out when the pressing part 31 presses against the loading cavity 21. Exemplarily, the material of the abutment part 312 is rubber or silicone. Rubber and silicone have a certain degree of flexibility and deformability, which can play a good sealing role.

[0043] As attached Figure 2-5 As shown, in some embodiments, the pressing part 31 is provided with an injection nozzle 313, which communicates with the cavity 311. When the amount of coating material in the loading cavity 21 is less than a preset amount, the coating material can be replenished to the loading cavity 21 through the injection nozzle 313.

[0044] As attached Figure 5 As shown, in some embodiments, the pressing part 31 is provided with a supporting part 314, and the injection nozzle 313 is disposed on the supporting part 314. The supporting part 314 is provided with a fixing part 3141, and the pressing part 31 is provided with a fixing groove 315. The fixing part 3141 is fixedly disposed on the fixing groove 315. The supporting part 314 is fixedly connected to the pressing part 31. When the pressing part 31 moves relative to the loading part 2, the injection nozzle 313 is stationary relative to the pressing part 31.

[0045] In some embodiments, the injection nozzle 313 is provided with a one-way valve (not shown) from which the coating material flows into the cavity 311. The one-way valve prevents the coating material entering the loading cavity 21 from flowing back out of the injection nozzle 313.

[0046] For example, the cable silicone grease coating device 100 is made entirely of corrosion-resistant material, and the bearing part 314 and the one-way valve are made of wear-resistant silicone material.

[0047] In some embodiments, the pressing part 31 is provided with a pressing wrench (not shown in the figure), which is located on the top of the pressing part 31 to facilitate pressing the pressing part 31.

[0048] In some embodiments, the coating section 1 is detachably connected to the loading section 2. The coating section 1 can be replaced according to the size of the cable 200, thus reducing the number of loading sections 2.

[0049] In some embodiments, the height of the guide pipe 22 is greater than the height of the loading cavity 21. The loading cavity 21 and the coating part 1 are located at opposite ends of the guide pipe 22, and a movable space 4 is provided between the loading cavity 21 and the coating part 1. When the pressing part 31 moves relative to the loading cavity 21, the movable space 4 facilitates the movement of the pressing part 31, and the movable space 4 provides space for the user's finger to press the pressing part 31.

[0050] In some embodiments, the flow channel 22 is provided with a regulating valve (not shown in the figure) for regulating the flow rate of the flow channel 22, thereby controlling the amount of coating material coated on the cable 200.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
