Description

[Technical Field]

[0001] The present invention relates to the field of cable-related technology, and more particularly to a protection device for heat dissipation of twisted cables in wind power generation units. [Background technology]

[0002] The twisted cables of existing wind power units are arranged compactly, with no physical isolation between them. Wind power unit personnel repeatedly inspected and measured the temperatures of the power cables inside the nacelle and tower of the wind power unit, and found that the temperature of the twisted cables was significantly higher than that of other parts. Especially when the wind power unit is yawing, if the twisted cables overheat for a long period of time, the insulation layer will deteriorate, putting the unit at risk of fire and seriously affecting the stable operation of the unit.

[0003] Because existing twisted cables are stuck together, the heat dissipation effect of the cables is poor, and the temperature of the cables becomes too high, making them more likely to catch fire. Summary of the Invention [Problem to be solved by the invention]

[0024] In order to clarify the technical concept of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

[0026] In order to make the above objects, features and advantages of the present invention more clearly comprehensible, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention; however, the present invention may be practiced in ways other than those described herein, and those skilled in the art will be able to make similar advancements without departing from the spirit and scope of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

[0028] As used herein, "one embodiment" or "embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places throughout this specification do not all refer to the same embodiment, nor do they refer to embodiments that are mutually exclusive of other embodiments, either singly or in the alternative. [Example]

[0029] Example 1 As shown in Figures 1 to 3, a protection device is provided for heat dissipation of twisted cables in wind power generation units, and includes a main body assembly 100 and a partition assembly 200. The main body assembly 100 includes a first insulating ring 101, a second insulating ring 102, and bolts 103. The rear end of the first insulating ring 101 and the rear end of the second insulating ring 102 are hingedly connected. There are four bolts 103, and the four bolts 103 are grouped in pairs. The two sets of bolts 103 are respectively provided on the sides of the first insulating ring 101 and the second insulating ring 102. The first insulating ring 101 and the second insulating ring 102 have the same structure. The first insulating ring 101 consists of an upper ring body and a lower ring body, and the upper ring body and the lower ring body are fixedly connected by the bolts 103. The bolts 103 make it easy to fix the upper ring body and the lower ring body.

[0030] The partition assembly 200 includes an inner locking groove 201, an outer locking groove 202, a through hole 203, a retaining ring 204, a plunger 205, and a spring 206. The inner locking groove 201 is provided on the inside of both the first insulating ring 101 and the second insulating ring 102, and the outer locking groove 202 is provided on the outside of both the first insulating ring 101 and the second insulating ring 102. A through hole 203 is provided on the upper surface of each of the rings 102, a retaining ring 204 is fixedly connected to the inner wall of the through hole 203, a plunger 205 is movably inserted onto the upper surface of the retaining ring 204, the lower end of the plunger 205 passes through the retaining ring 204 and is movably inserted onto the upper surface of the second insulating ring 102, a spring 206 is fixedly fitted onto the side of the plunger 205, and the upper end of the spring 206 is fixedly connected to the bottom surface of the retaining ring 204. The first insulating ring 101 and the second insulating ring 102 are closed together to form a ring shape, and the second insulating ring 102 abuts against the plunger 205, moving the plunger 205 upward. The plunger 205 is then moved downward by the spring 206 and inserted into the lower through-hole 203, and the plunger 205 is then fixed together with the first insulating ring 101 and the second insulating ring 102, making it easy and convenient to join the device together. [Example]

[0031] Example 2 As shown in Figures 1 and 2 of the instruction manual, the difference from the previous embodiment is that the first insulating ring 101 and the second insulating ring 102 are both thermoplastic resin rings, which have strong impact resistance, corrosion resistance, high temperature resistance, and excellent toughness, and have outstanding strength-bearing properties among engineering plastics.

[0032] There are twelve inner locking grooves 201, and two first buckles 201a are fixedly connected to the sides of each of the twelve inner locking grooves 201. The first buckles 201a are arc-shaped plastic plates. The inner locking grooves 201 make it easy to sequentially arrange the internal cables, and by fixing the internal cables with the first buckles 201a, the possibility of the cables and inner locking grooves 201 becoming detached is reduced.

[0033] There are twelve outer locking grooves 202, and two second buckles 202a are fixedly connected to the sides of each of the twelve outer locking grooves 202. The second buckles 202a are arc-shaped plastic plates. The outer locking grooves 202 make it easy to sequentially route external cables, and by fixing the external cables via the second buckles 202a, the possibility of the cables and outer locking grooves 202 becoming detached is reduced.

[0034] Sponge is adhered to the inner walls of the inner locking groove 201 and the outer locking groove 202. The sponge helps protect the cable. In addition, the combination of the inner locking groove 201 and the outer locking groove 202 physically isolates the twisted cable, providing sufficient clearance for the twisted cable, which reduces the environmental temperature around a single cable and prevents the cable from being exposed to harsh environments such as overheating and friction for long periods of time. It also provides the cable with a well-ventilated and heat-dissipating environment, helping to eliminate the risk of unit fire. [Example]

[0035] Example 3 The difference from the previous two embodiments is that, as shown in Figure 3 of the instruction manual, plunger 205 is composed of a T-shaped rod and a ring, and the ring is fixedly fitted onto the side of the T-shaped rod, and the upper surface of the ring is fixedly connected to the lower end of spring 206. Spring 206 moves plunger 205 downward and inserts it into second insulating ring 102, thereby fixing first insulating ring 101 and second insulating ring 102 together.

[0036] The bottom end of plunger 205 has an obliquely cut surface, and pull ring 205a is fixedly connected to the top of plunger 205. When second insulating ring 102 abuts against plunger 205 due to the obliquely cut surface, plunger 205 automatically moves upward. Spring 206 then returns plunger 205 to its original position and inserts it into second insulating ring 102, eliminating the need for an operator to manually pull or move plunger 205. When it is necessary to remove the device, pull ring 205a is pulled up, plunger 205 moves upward, and it separates from second insulating ring 102, and the device is opened and removed from the cable.

[0037] It should be noted that the above examples are intended to illustrate the technical idea of ​​the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that the invention falls within the scope of the claims of the present invention without departing from the spirit and scope of the present invention.
