Description

Technical Field

[0001] This utility model relates to the field of wind power generation tower technology, and in particular to a heat dissipation mechanism at the base of a wind power generation tower. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. A wind turbine typically consists of a wind turbine, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. The working principle of a wind turbine is relatively simple: the wind turbine rotates under the influence of wind, converting the kinetic energy of the wind into the mechanical energy of the turbine shaft. The generator rotates under the drive of the turbine shaft to generate electricity. Broadly speaking, wind energy is also solar energy, so a wind turbine can also be described as a thermal energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] During the energy conversion process, wind turbine towers generate a lot of heat. Existing heat dissipation devices can only conduct heat into the tower body, which is inefficient. In addition, the conductive cables generate a lot of heat during energy conversion, and the heat cannot be effectively dissipated. Over time, this will cause the cables to age and reduce their service life.

[0004] To address this issue, we propose a heat dissipation mechanism at the base of a wind power tower. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation mechanism at the base of a wind power tower to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation mechanism at the base of a wind turbine tower, comprising:

[0008] A heat dissipation mechanism is used to dissipate heat from a wind turbine tower. The heat dissipation mechanism includes a base plate fixedly welded inside the wind turbine tower. A heat-conducting plate is fixedly installed on the upper end of the base plate. Two vertical plates are fixedly welded to the heat-conducting plate. Two bidirectional threaded rods are rotatably connected between the two vertical plates. Two push plates are threadedly fitted onto the outside of each of the two bidirectional threaded rods. The push plates are slidably connected to the heat-conducting plate. One end of each of the two bidirectional threaded rods rotatably passes through the vertical plate and is connected to a transmission mechanism. One end of one of the bidirectional threaded rods rotatably passes through the vertical plate and is coaxially fixedly connected to a handle. A heat-conducting column is fixedly installed at the lower end of the base plate. A heat-conducting plate is fixedly welded through the base plate and fixedly connected to the heat-conducting column. Multiple L-shaped heat-conducting plates are fixedly welded to the periphery of the heat-conducting column. The multiple L-shaped heat-conducting plates extend to the outside of the wind turbine tower and are buried in the ground.

[0009] Furthermore, the transmission mechanism includes two pulleys, which are coaxially and fixedly connected to two bidirectional threaded rods, and the two pulleys are connected by a synchronous belt drive.

[0010] Furthermore, both push plates located outside the same bidirectional threaded rod are provided with threaded holes that match the bidirectional threaded rod, and the threads in the two threaded holes have opposite directions.

[0011] Furthermore, the external threads of the two bidirectional threaded rods are rotated in opposite directions.

[0012] Furthermore, the heat-conducting plate has grooves at both its upper and lower ends.

[0013] Furthermore, multiple L-shaped heat-conducting plates are evenly distributed in an array around the heat-conducting pillar.

[0014] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0015] By setting up a heat dissipation mechanism, the cable is placed on the back of the heat-conducting plate through a cable groove and is in close contact with the heat-conducting plate. At this time, the two bidirectional threaded rods are rotated by the handle, and the two bidirectional threaded rods drive the four push plates to move relative to each other. The four push plates can then push the cable to move, thereby tightening the cable and increasing the contact area between the cable and the heat-conducting plate, improving the heat conduction efficiency of the cable. Moreover, the heat from the wind turbine tower can be sequentially introduced into the heat-conducting column and L-shaped heat-conducting plate through the heat-conducting plate and transferred to the ground. This effectively dissipates the heat generated by the wind turbine tower and the heat from the cable, extending the service life of the cable.

[0016] This invention can effectively dissipate heat from wind power towers and cables, extending the service life of cables and improving heat dissipation efficiency. Attached Figure Description

[0023] Please see Figures 1-4 A heat dissipation mechanism at the base of a wind power tower, comprising:

[0024] The heat dissipation mechanism 1 is used to dissipate heat from the wind turbine tower. The heat dissipation mechanism 1 includes a base plate 2 fixedly welded inside the wind turbine tower. A heat-conducting plate 3 is fixedly installed on the upper end of the base plate 2. It should be noted that the wind turbine tower has a door hinged to the tower body corresponding to the heat-conducting plate 3, which facilitates the maintenance of the wind turbine tower. It should be noted that the upper and lower ends of the heat-conducting plate 3 are provided with wire grooves 12. Two vertical plates 4 are fixedly welded to the heat-conducting plate 3. Two bidirectional threaded rods 5 are rotatably connected between the two vertical plates 4. It is worth mentioning that the external threads of the two bidirectional threaded rods 5 have opposite directions. Two push plates 6 are threaded on the outside of the two bidirectional threaded rods 5. It is worth mentioning that the two push plates 6 located outside the same bidirectional threaded rod 5 are provided with threaded holes that match the bidirectional threaded rod 5. The threads in the two threaded holes have opposite directions. The push plates 6 are slidably connected to the heat-conducting plate 3. One end of each of the two bidirectional threaded rods 5 rotatably passes through the vertical plate 4 and is connected by transmission mechanism 7.

[0025] In this utility model, the transmission mechanism 7 includes two pulleys 11, which are coaxially fixedly connected to two bidirectional threaded rods 5 respectively. The two pulleys 11 are connected by a synchronous belt drive. One end of one bidirectional threaded rod 5 rotates through the vertical plate 4 and is coaxially fixedly connected to a handle 8. A heat-conducting column 9 is fixedly installed at the lower end of the base plate 2. A heat-conducting plate is fixedly welded through the base plate 2 and fixedly welded to the heat-conducting column 9. Multiple L-shaped heat-conducting plates 10 are fixedly welded to the periphery of the heat-conducting column 9. The multiple L-shaped heat-conducting plates 10 extend to the outside of the wind power tower and are buried in the ground. It should be noted that the multiple L-shaped heat-conducting plates 10 are evenly distributed in an array on the periphery of the heat-conducting column 9.

[0026] Using the aforementioned technical features, the cable is placed on the back of the heat-conducting plate 3 through the cable groove 12 and is in contact with the heat-conducting plate 3. At this time, the two bidirectional threaded rods 5 are rotated by the rotating handle 8. The two bidirectional threaded rods 5 drive the four push plates 6 to move relative to each other. The four push plates 6 can push the cable to move, thereby tightening the cable and increasing the contact area between the cable and the heat-conducting plate. The equipment inside the wind power tower is installed on the heat-conducting plate 3, and the heat from the wind power tower can be sequentially introduced into the heat-conducting column 9 and the L-shaped heat-conducting plate 10 through the heat-conducting plate 3 and then transferred to the ground.
