Description

Technical Field

[0001] This utility model relates to the field of power cable technology, specifically a water-blocking power cable. Background Technology

[0002] The development of cable types must adapt to a wide range of applications and methods. With a deeper understanding of water absorption and water treeing in the insulation layers between cable cores, people are increasingly aware of the importance of waterproof performance for medium and high voltage power cables, especially in applications near the sea or in areas with high humidity.

[0003] In the prior art, for example, a water-blocking power cable disclosed in publication number CN214099205U describes: by setting a braided mesh, which usually has a certain toughness and strength, the braided mesh cannot be easily torn when scratched by a sharp object, thus protecting the cable; by setting a toughness strip, the toughness strip can increase the toughness of the cable, and when the cable is bent and stretched, the cable can have better toughness, thereby reducing the probability of internal conductor breakage during the stretching and bending process.

[0004] In actual use, it is difficult to arrange the same structure at the joint of the above-mentioned device. Also, since some machines used for waterside operations are relatively large and require direct cable connection, the device joint needs to be used outdoors. When part of the equipment enters the water for operation, the device must be used close to the water. Since the joint needs to be connected, it cannot be completely sealed, and moisture can easily penetrate the inside of the joint. In addition, since most of the cable is left in the water, the joint is easily detached due to the pulling of waves or flowing water. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] It solves the problem that moisture intrusion at the joint can easily lead to moisture accumulation, thereby causing a short circuit at the joint; it also solves the problem that cables are easily detached when pulled by waves or water flow.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-3 The first embodiment of this utility model provides a water-blocking power cable, including a plug socket 1, a cable 11 fixedly connected to one side of the plug socket 1, an outer frame 12 fixedly connected to one side of the plug socket 1, the cross-sectional shape of the outer frame 12 is a regular hexagon, and a plug 13 is fixedly connected to the inner side of the outer frame 12.

[0029] It also includes a dehumidification structure installed in the plug socket 1;

[0030] The dehumidification structure includes an adapter pipe 21 mounted on the outer frame 12. The adapter pipe 21 is connected through a round hole on the outer frame 12. An installation hole 22 is opened in the plug socket 1. The installation hole 22 is divided into two parts. The middle part with a larger inner diameter is used to install the fan frame 23 and other structures. The two ends with smaller inner diameters are used to connect the adapter pipe 21 and install the filter screen 26, and are mainly used for ventilation. There are two fan frames 23 fixed in the installation hole 22, which are symmetrically arranged in the installation hole 22. A fan 24 is rotatably connected in the fan frame 23. The fan 24 is rotatably connected to the two fan frames 23 through a shaft. Fan blades 25 are fixed on the fan 24. A filter screen 26 is set on one side of the fan 24.

[0031] A support frame 27 is fixedly connected to one side of the fan 24, and a connecting end 14 is provided on one side of the outer frame 12. The connecting end 14 is provided on the electrical equipment.

[0032] A connector 15 is fixedly connected to one side of the connecting end 14. The connector 15 and the plug 13 are used together. A fastening structure is provided on the outer frame 12.

[0033] During use, first insert plug 13 into connector 15 to complete the connection of electrical equipment and cable 11. Then, start the plug socket 1 and connect the current. Start the fan 24 to drive the fan blades 25 connected to the fan 24 to rotate, thereby causing the fan blades 25 to circulate air and expel the humid air in the adapter pipe 21. This keeps the internal air circulating, so that humid air will not accumulate in plug 13. The end that discharges humid air is equipped with a filter screen 26, which can prevent dust and dirt from entering the device and avoid dust and dirt affecting the use of the device.

[0034] Example 2

[0035] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the fastening structure includes a plug plate 31 fixed on the outer frame 12. The plug plate 31 is used to fix the plug 13 and the connector 15. A limiting groove 32 is opened on the plug plate 31. The cross-sectional shape of the limiting groove 32 is the same as the cross-sectional shape of the pin 34.

[0036] A base 33 is fixedly connected to the connecting end 14. The base 33 is fixed to the connecting end 14 and has a square hole in the middle for the pin 34 to pass through. The pin 34 is movably connected to the base 33. One side of the pin 34 has an arc surface. When the insert plate 31 passes through the middle position of the two pins 34, the arc surface can push the two pins 34 open.

[0037] A connecting plate 35 is fixedly connected to one side of the pin 34. The connecting plate 35 is used to connect the spring 36 and the base 33. A spring 36 is fixedly connected to one side of the connecting plate 35. The other end of the spring 36 is fixed to the base 33. There are two springs 36 on one connecting plate 35. The base 33, pin 34, connecting plate 35, and spring 36 are all symmetrically arranged on one surface of a connecting end 14.

[0038] During use, when connector 15 and plug 13 are connected, the insert plate 31 passes between the two pins 34, thereby opening the curved side of the pin 34 and allowing the pin 34 to move in the square hole of the base 33. During this process, the pin 34 will drive the spring 36 fixed to the connecting plate 35 to stretch until the limiting groove 32 is directly below the pin 34. At this time, the pin 34 loses the support of the insert plate 31, which will cause the stretched spring 36 to rebound, thereby forcing the pin 34 to return to its original position. At this time, the pin 34 will enter the limiting groove 32, thereby completing the position limitation of the insert plate 31, that is, tightening the plug 13 connected to the insert plate 31, so that the plug 13 and connector 15 are stably connected.

[0039] The remaining structure is the same as that in Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
