Description

Technical Field

[0001] This application relates to the field of cable monitoring technology, and more specifically, to a device for monitoring the status of medium-voltage cable shore power connection. Background Technology

[0002] Shore power cable is a marine engineering term referring to a specialized cable used to connect a ship's shore power box to the shore-based power grid or other ship power sources via a plug and socket. The cable conductor is made of tinned copper wire, the insulation layer is ethylene propylene rubber, and the outer sheath is made of chlorinated polyethylene rubber. The intelligent connection system is equipped with cable reels, lifting devices, and an automatic control system to achieve constant tension cable reeling and unloading, ship-shore adaptive docking, and collision warning functions. The "Shore Power Universal Box" installed in ports can serve as a junction box, adaptable to various socket interfaces. During the shore power cable connection process, a partial discharge detection system is used to monitor its status.

[0003] Existing technologies assess insulation status by detecting partial discharge signals inside the cable, such as electrical pulses, ultrasonic waves, and ultra-high frequency electromagnetic waves, supporting threshold warnings and fault location. However, when monitoring the cable, it is usually necessary to manually hold the inductive contact in the partial discharge detection equipment. If the cable discharges abnormally, it may pose a danger to the user, making it inconvenient to conduct safer testing. Summary of the Invention

A partial discharge monitoring device body 2 is located on the left side of the inductive contact 1, and the inductive contact 1 is part of the partial discharge monitoring device body 2, with the two connected by a circuit. The partial discharge monitoring device body 2 is used to read and detect the data sensed by the inductive contact 1. An adjustment component 3 is located on the back of the inductive contact 1, used to adjust the position of the inductive contact 1, allowing it to move left and right and rise and fall.

The second electric push rod 306 is used to push the sensing contact 1 up and down. A limit block 307 is movably attached to the right side of the first sliding seat 304. The limit block 307 is used to limit the position of the first sliding seat 304, so that the protective component 4 can provide tight protection for the first sliding seat 304. The limit block 307 is fixedly connected to the front of the support plate 301. A protective component 4 is provided on the outer surface of the sensing contact 1. The protective component 4 is used to protect the sensing contact 1 when it is not in use to prevent damage to the sensing contact 1. Component 4 includes a protective block 401, which is fan-shaped and fixedly connected to the left side of the first sliding seat 304. A protective plate 402, which is semi-circular in shape, is fixedly connected to the outer surface of the first sliding seat 304 and the second electric push rod 306. The protective plate 402 is fixedly connected to the top of the protective block 401. A protective shell 403 is hinged to the front of the support plate 301. The protective shell 403 corresponds to the protective plate 402 and the protective block 401 and can be fastened to form a cover to protect the sensing contact 1. A connecting seat 404, which is C-shaped, is fixedly connected to the front of the protective shell 403. A pushing component 5 is provided above the protective component 4 to push the protective component 4 to open it.This removes the protection of the sensing contact 1 and allows the adjustment component 3 to adjust the sensing contact 1. The pushing component 5 includes a second slide rail 501 with a trapezoidal cross-section. The second slide rail 501 is fixedly connected to the front of the support plate 301. A second sliding seat 502 is slidably connected to the front of the second slide rail 501. The second sliding seat 502 is L-shaped and has a dovetail groove on its back for sliding on the second slide rail 501. A third electric push rod 503 is fixedly connected to the left side of the second sliding seat 502. The output end of the third electric push rod 503 is connected to the second sliding seat 502 and is used to push the second sliding seat 502 to slide left and right on the second slide rail 501.

A retaining assembly 6 for fixing the partial discharge monitoring device body 2 is mounted on the outer surface of the body. The retaining assembly 6 is used to place and fix the partial discharge monitoring device body 2. An adsorption assembly 7 for adsorbing onto a flat surface is mounted on the back of the support plate 301. The adsorption assembly 7 is used to adsorb the support plate 301 onto the flat surface of the cable connection, thus fixing the initial position of the sensing contact 1. The sensing contact 1 can then be remotely adjusted to be close to the cable connection for monitoring. The adsorption assembly 7 includes a hollow chamber 701, which is fixedly connected to the back of the support plate 301. Two suction cups 702 are fixedly connected to the back of the chamber 701, and the suction cups 702 are interconnected.

[0025] In practical use, the above-mentioned device is first used to place the support plate 301 against the plane of the cable connection by using the handle 302, so that the suction cup 702 on the back of the support plate 301 is attached to the plane to fix the support plate 301. When it is necessary to monitor the partial discharge at the cable connection, the second sliding seat 502 is pushed to the right on the second slide rail 501 by activating the third electric push rod 503. The second sliding seat 502 will drive the push arm 504 to push the connecting seat 404 to the right, thereby causing the protective shell 403 to flip to the right. At this time, the protective shell 403 opens to expose the sensing contact 1. The first electric push rod 305 is activated to pull the first sliding seat 304 to slide to the left on the first slide rail 303. The sliding of the first sliding seat 304 will drive the second electric push rod 306 to move the sensing contact 1 so that the sensing contact 1 is aligned with the cable connection. At this time, the second electric push rod 306 is activated to drive the sensing contact 1 to rise and fall so that it can approach and fit against the cable connection for partial discharge monitoring.

[0026] Example 2, see Figures 1-8The retaining assembly 6 includes two support plates 601, which are respectively located on the left and right sides of the partial discharge monitoring device body 2. The support plates 601 are fixedly connected to the front of the support plate 301. A retaining seat 602 is provided on the front of the support plate 601. The retaining seat 602 is T-shaped, appearing T-shaped from both the front and top views. A first spring 603 is elastically connected between the retaining seat 602 and the support plate 601. The first spring 603 is used to reset the retaining seat 602 after movement. A sliding groove 604 is provided on the front of the retaining seat 602. A limiting slider 605 is slidably connected to the inner surface of the sliding groove 604. The limiting slider 605 is T-shaped and fixedly connected to the front of the support plate 601. The retaining seat 602, the first spring 603, and the first spring 604 are all T-shaped. The number of springs 603, slides 604, and limiting sliders 605 are all two. A blocking component 8 is provided on the back of the card holder 602 to prevent it from moving, thereby maintaining the limiting and fixing of the partial discharge monitoring device body 2. The card holder component 6 also includes a support base 606, which is L-shaped and fixedly connected to the front of the support plate 301. A top plate 607 is provided on the inner surface of the support base 606. Two second springs 608 are elastically connected between the top plate 607 and the inner surface of the support base 606. A pull seat 609, which is T-shaped, is fixedly connected to the front of the top plate 607 and penetrates the front of the support base 606. The blocking component 8 includes a third slide rail 801 with a trapezoidal cross-section. The third slide rail 801 is fixedly connected to the back of the support plate 301. A third sliding seat 802 is slidably connected to the back of the third slide rail 801. The front of the third sliding seat 802 has a dovetail groove for sliding on the third slide rail 801. Two guide grooves 803 are provided on the top of the third sliding seat 802. Two guide rods 804 are slidably connected to the inner surface of each guide groove 803. Limiting posts 805 are fixedly connected to both the upper and lower ends of each guide rod 804. The limiting posts 805 are slidably connected to the back of the support plate 301. Limiting posts 805 are slidably connected to the outer surface of the limiting posts 805. The limiting sleeve 806 is fixedly connected to the outer surface of the support plate 601. A hydraulic component 9 is provided on the right side of the third sliding seat 802. The hydraulic component 9 is used to drive the clamping component 6 to move by pushing the component 5. When the pushing component 5 pushes the protective component 4 to open, it will also drive the hydraulic component 9 to release the blocking component 8 from fixing the clamping component 6. The hydraulic component 9 includes a first hydraulic chamber 901, which is fixedly connected to the back of the support plate 301. A first hydraulic rod 902 is slidably connected to the inner surface of the first hydraulic chamber 901. The first hydraulic rod 902 is fixedly connected to the right side of the pushing seat 505. A second hydraulic chamber 903 is fixedly connected to the back of the support plate 301. The second hydraulic chamber 903 is connected to the first hydraulic chamber 901 by pipeline.The second hydraulic chamber 903 is connected to the first hydraulic chamber 901 via a hose. Both chambers contain hydraulic oil. The volume of the second hydraulic chamber 903 is the same as that of the first hydraulic chamber 901. A second hydraulic rod 904 is slidably connected to the inner surface of the second hydraulic chamber 903, and the second hydraulic rod 904 is fixedly connected to the right end of the third sliding seat 802.

[0027] In practical use, when the third electric push rod 503 pushes the second sliding seat 502 to slide to the right on the second slide rail 501, the second sliding seat 502 also drives the push seat 505 to move to the right. At this time, the push seat 505 pushes the first hydraulic rod 902 to retract into the first hydraulic chamber 901. The first hydraulic rod 902 pushes the hydraulic oil in the first hydraulic chamber 901 to be injected into the second hydraulic chamber 903 through the hose, thereby pushing the second hydraulic rod 904 to extend from the second hydraulic chamber 903. The second hydraulic rod 904 pushes the third sliding seat 802 to slide to the left on the third slide rail 801. The movement of the third sliding seat 802 will cause the guide groove 803 to push against the guide rod. 804, causing the guide rod 804 to move away from the support plate 301. At this time, the guide rod 804 will drive the limiting pin 805 to slide backward within the limiting sleeve 806, so that the limiting pin 805 can no longer hold the card seat 602. At this time, by pushing the card seat 602 to move it away from the partial discharge monitoring device body 2, the sliding groove 604 on the card seat 602 will slide on the limiting slider 605. The card seat 602 will move away from the front of the partial discharge monitoring device body 2 and will no longer block the partial discharge monitoring device body 2. The partial discharge monitoring device body 2 can then be removed from the support base 606, so that the user can remove the partial discharge monitoring device body 2 for remote operation, achieving the purpose of safety.

[0028] Example 3, see Figures 1-8 The adsorption component 7 also includes a T-shaped three-way pipe 703, which is fixedly connected to the back of the support plate 301. A connecting pipe 704 is fixedly connected between the three-way pipe 703 and the chamber 701. The three-way pipe 703, the connecting pipe 704, and the chamber 701 are interconnected. A venting valve 705 is fixedly connected to the top of the chamber 701 and is connected to the chamber 701. The opening and closing of the venting valve 705 allows the air chamber 706 to be connected to or closed to the outside. An air chamber 706 is fixedly connected to the back of the support plate 301. The air chamber 706 is connected to the three-way pipe 703 by a pipeline. The air chamber 706 and the three-way pipe 703 are connected and communicated by a flexible hose. A piston rod 707 is slidably connected to the inner surface of the air chamber 706 and is fixedly connected to the left side of the push seat 505.

[0029] In practical use, when the second sliding seat 502 drives the push seat 505 to move to the right, the push seat 505 will also pull the piston rod 707 to slide to the right in the air chamber 706. At this time, the piston rod 707 will draw gas from the three-way pipe 703 through the hose. The gas in the chamber 701, which is connected to the three-way pipe 703 through the connecting pipe 704, will be drawn into the air chamber 706, which will increase the negative pressure of the suction cup 702, thereby enhancing the suction force of the suction cup 702 and making it difficult for the support plate 301 to fall off the plane. When it is necessary to remove the support plate 301 from the plane, the chamber 701 will be connected to the outside by opening the vent valve 705. The suction cup 702 will lose the negative pressure and thus lose its suction force, so that the support plate 301 can be removed from the plane.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
