Description

Technical Field

[0001] This application relates to the field of cable equipment maintenance, and in particular to a high-efficiency cable insulation core dewatering device. Background Technology

[0002] In complex construction environments, especially in southern regions, cables inevitably face the risk of water immersion during their laying path. Factors such as damaged cable sheaths or unreliable end seals can cause moisture to enter the cable core, leading to water trees forming shortly after operation, as well as breakdown accidents at intermediate joints and terminals. This can result in large-scale power outages, factory shutdowns, and a series of other problems, causing economic losses and inconvenience to daily life and travel.

[0003] Previously, the way to deal with water-inundated cables was to cut them off and scrap them in a dry place, or replace them with new cables. This resulted in a lot of economic waste and also caused excessively long construction time. Utility Model Content

[0004] To address the aforementioned issues, this application provides a high-efficiency cable insulation core dehydration device.

[0005] The high-efficiency cable insulation core dehydration device provided in this application adopts the following technical solution:

[0006] A high-efficiency cable insulation core dehydration device includes an air inlet and an air supply pipe. One end of the air inlet is connected to the air supply pipe, and the other end is used to detachably connect and communicate with the end of the cable core. The end of the air supply pipe away from the air inlet is used to connect to an air pump.

[0007] By adopting the above technical solution, after the vent connector is connected to the end of the wire core, the air pump can introduce airflow into the wire core through the air supply pipe and the vent connector. The airflow accelerates the drying of the moisture inside the wire core, thereby achieving the purpose of removing water.

[0008] Preferably, the venting connector includes a positioning ring and a docking cylinder. One end of the docking cylinder is coaxially connected and communicates with the gas supply pipe. The positioning ring is located at the end of the docking cylinder away from the gas supply pipe. The positioning ring and the docking cylinder are coaxial. The positioning ring is sleeved on the wire core and is detachably coaxially connected to the wire core. A connector is provided between the docking cylinder and the positioning ring. The connector is used to control the relative distance between the docking cylinder and the positioning ring along the axial direction.

[0009] By adopting the above technical solution, after the positioning ring and the wire core are relatively fixed, the connector shortens the distance between the positioning ring and the docking cylinder, thereby making the docking cylinder tightly fit the end of the wire core, achieving connection and sealing.

[0010] Preferably, the positioning ring body is threaded with a plurality of locking bolts, the ends of which abut against the sidewall of the wire core.

[0011] Preferably, the connecting element is a connecting bolt, and a connecting flange is coaxially fixedly connected to the docking cylinder. The connecting bolt passes through the connecting flange and is threadedly connected to the positioning ring. The length direction of the connecting bolt is parallel to the axis of the docking cylinder. The number of connecting bolts is greater than or equal to three, and multiple connecting bolts are arranged in an array around the docking cylinder.

[0012] By adopting the above technical solution, after fixing the positioning ring and the wire core relatively, tightening the connecting bolts will bring the docking cylinder close to the positioning ring, so that the inner wall of the docking cylinder can press against the end of the wire core.

[0013] Preferably, the docking cylinder is a conical cylinder, and the radial dimension of the docking cylinder increases along the direction close to the positioning ring, with the end edge of the wire core abutting against the inner wall of the docking cylinder.

[0014] By adopting the above technical solution, the inner diameter of the docking cylinder can be varied. After the connecting bolts are tightened, the docking cylinder can adaptably abut and seal against various wire cores.

[0015] Preferably, when the number of wire cores in the cable is greater than one, the number of venting connectors is consistent with the number of wire cores and corresponds one-to-one. The air supply pipe is provided with a multi-port connector, and the air supply pipe is divided into multiple branch pipes through the multi-port connector. Each branch pipe is connected to a venting connector.

[0016] By adopting the above technical solution, for multi-core cables, the multi-connector allows multiple cores to receive the same airflow from the same air pump.

[0017] Preferably, the plurality of locking bolts are arranged in a circumferential array around the positioning ring, and the positioning ring is provided with a synchronization component for synchronizing the rotation of all locking bolts.

[0018] By adopting the above technical solution, the synchronization component enables all locking bolts to move synchronously, and the distance between each locking bolt and the axis of the positioning ring can be kept consistent, thereby improving the coaxiality of the core and the positioning ring.

[0019] Preferably, the synchronization component includes a synchronization gear ring and a synchronization gear. The synchronization gear ring and the positioning ring are coaxially rotatably connected. The number of synchronization gears and locking bolts are the same and correspond one-to-one. The synchronization gears are coaxially sleeved on the outside of the locking bolts. The synchronization gears and the positioning ring are rotatably connected. All synchronization gears mesh with the synchronization gear ring simultaneously. An anti-rotation protrusion is fixedly connected to the inner edge of the synchronization gear. A synchronization groove is opened on the locking bolt. The length direction of the synchronization groove is parallel to the length direction of the locking bolt. The anti-rotation protrusion is located in the synchronization groove and abuts against the groove wall of the synchronization groove.

[0020] Preferably, the length direction of the locking bolt is inclined relative to the radial direction of the positioning ring, the end of the locking bolt near the wire core is close to the docking cylinder, and the end of the locking bolt is ball-jointed with a contact block, the contact block abutting against the side wall of the wire core.

[0021] By adopting the above technical solution, when the wire core is subjected to the abutting force from the docking cylinder, the locking bolt has a stronger abutting force on the wire core, thereby increasing the relative stability of the positioning ring and the wire core.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a venting connector and an air supply pipe, after the venting connector is connected to the end of the wire core, the air pump can introduce airflow into the wire core through the air supply pipe and the venting connector. The airflow accelerates the drying of the moisture inside the wire core, thereby achieving the purpose of removing water.

[0024] 2. Due to the conical design of the docking cylinder, the inner diameter of the docking cylinder can vary. When the connecting bolts are tightened, the docking cylinder can adaptably meet and seal various wire cores. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] Example 1:

[0031] This application discloses a high-efficiency cable insulation core dehydration device, such as... Figure 1 As shown, it includes a venting connector 3 and an air supply pipe 2. One end of the venting connector 3 is connected to the air supply pipe 2, and the other end is used to detachably connect and communicate with the end of the cable core 1. The end of the air supply pipe 2 away from the venting connector 3 is used to connect to an air pump. After the air pump is turned on, airflow can be pumped into the core 1 through the air supply pipe 2 and the venting connector 3.

[0032] like Figure 1 As shown, the vent connector 3 includes a positioning ring 31 and a docking cylinder 33. One end of the docking cylinder 33 is coaxially connected to and communicates with the gas supply pipe 2. The positioning ring 31 is located at the end of the docking cylinder 33 away from the gas supply pipe 2, and the two are coaxial. The docking cylinder 33 is a conical cylinder, with a smaller diameter at the end connected to the gas supply pipe 2. The radial dimension of the docking cylinder 33 increases along the direction close to the positioning ring 31.

[0033] like Figure 1 As shown, the positioning ring 31 is sleeved on the wire core 1 and detachably coaxially connected to the wire core 1. Multiple locking bolts 32 are threaded onto the positioning ring 31. The length direction of the locking bolts 32 is radial to the positioning ring, and the ends of the locking bolts 32 abut against the sidewall of the wire core 1. In this embodiment, there are three locking bolts 32, arranged in an array around the positioning ring. When the ends of the locking bolts 32 simultaneously abut against the sidewall of the wire core 1, the positioning ring and the wire core 1 are coaxially fixed.

[0034] like Figure 1 As shown, a connector is provided between the docking cylinder 33 and the positioning ring 31. The connector is used to control the relative distance between the docking cylinder 33 and the positioning ring 31 along the axial direction. The connector is a connecting bolt 34. A connecting flange 331 is integrally formed coaxially at one end of the docking cylinder 33 near the positioning ring 31. The connecting bolt 34 passes through the connecting flange 331 and is threadedly connected to the positioning ring 31. The length direction of the connecting bolt 34 is parallel to the axis of the docking cylinder 33. There are three connecting bolts 34, which are arranged in an array around the docking cylinder 33. After the positioning ring 31 and the wire core 1 are fixed relative to each other, the connecting bolt 34 is tightened, so that the docking cylinder 33 is close to the positioning ring 31, and the inner wall of the docking cylinder 33 can press against the end of the wire core 1.

[0035] like Figure 1 and 2As shown, for a single-core cable 1, the vent connector 3 is directly connected to the air pump through the air supply pipe 2. For a multi-core cable 1, the number of vent connectors 3 must be consistent with the number of cores 1 and correspond one-to-one. The air supply pipe 2 is equipped with a multi-port connector 21. The air supply pipe 2 is divided into multiple branch pipes through the multi-port connector 21. Each branch pipe is connected to a vent connector 3. Multiple vent connectors 3 are connected to a single air pump through the multi-port connector 21.

[0036] Example 2:

[0037] like Figure 3 As shown in Embodiment 1, the three locking bolts are independent, making it difficult to ensure the consistency of the distance between the ends of each locking bolt and the axis of the positioning ring 31. Therefore, based on Embodiment 1, this embodiment also includes a synchronization component 4. The synchronization component 4 includes a synchronization gear ring 41 and synchronization gears 42. The synchronization gear ring 41 and the positioning ring 31 are coaxially rotatably connected. The number of synchronization gears 42 and locking bolts 32 are the same and correspond one-to-one. The synchronization gears 42 are coaxially sleeved on the outside of the locking bolts 32. The synchronization gears 42 and the positioning ring 31 are rotatably connected. All synchronization gears 42 mesh with the synchronization gear ring 41 simultaneously. When the synchronization gear ring 41 rotates relative to the positioning ring 31, all synchronization gears 42 also rotate synchronously. An anti-rotation protrusion 421 is fixedly connected to the inner edge of the synchronizing gear 42. A synchronizing groove 322 is provided on the locking bolt 32. The length direction of the synchronizing groove 322 is parallel to the length direction of the locking bolt 32. The anti-rotation protrusion 421 is located in the synchronizing groove 322 and abuts against the groove wall of the synchronizing groove 322. When the synchronizing gear 42 rotates, it can transmit torque to the locking bolt 32 through the anti-rotation protrusion 421, thereby driving it to rotate, thus realizing the synchronous rotation control of all locking bolts 32.

[0038] like Figure 3 As shown, the length direction of the locking bolt 32 is inclined radially relative to the positioning ring 31. The end of the locking bolt 32 closest to the core 1 is close to the docking cylinder 33. When the core 1 is subjected to an abutting force from the docking cylinder 33, the abutting force of the locking bolt 32 on the core 1 is stronger, thus increasing the relative stability between the positioning ring 31 and the core 1. To reduce contact damage to the sidewall of the core 1 caused by the sharp edges of the locking bolt 32, a contact block 321 is ball-jointed to the end of the locking bolt 32. The contact block 321 directly contacts and abuts the sidewall of the core 1.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
