Description

Technical Field

[0001] This invention relates to a high-efficiency wind turbine silo heat dissipation device, belonging to the technical field of wind turbine auxiliary equipment. Background Technology

[0002] The wind turbine silo is the interior of the generator tower. Existing wind turbines generally have cooling devices installed inside the generator nacelle, but rarely inside the generator tower. Cables are installed inside the generator tower. As the wind turbine nacelle rotates under the influence of wind, the cables inside the tower become entangled. Friction between the cables affects heat dissipation. In addition, the continuous high temperature inside the tower can easily cause the cables inside the tower to age and shorten their service life. Therefore, it is necessary to cool down the inside of the wind turbine tower and the cables inside the tower. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-efficiency wind turbine silo heat dissipation device to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this invention is as follows: a high-efficiency wind turbine silo heat dissipation device, including a sheath, a coolant tank, and a heat dissipation box. The sheath is fixed to the outer periphery of the cable, and a cavity is provided on the inner side wall of the sheath. The sheath is a flexible sheath. The cavity of the sheath is connected to the interior of the coolant tank through a one-way inlet valve and a first flexible hose. The cavity of the sheath is connected to a second flexible hose through a one-way outlet valve. The middle part of the second flexible hose is located inside the heat dissipation box, and one end of the second flexible hose away from the one-way outlet valve is connected to the interior of the coolant tank. A fan is provided inside the heat dissipation box. The inlet end of the fan is connected to the outside through an air inlet pipe, and the outlet end of the fan is connected to the outside through an exhaust pipe. The outlet end of the exhaust pipe is located above the inlet end of the air inlet pipe.

[0005] Preferably, a first rotating shaft is rotatably connected inside the coolant tank, the first hose is a steel wire hose, the first hose is coiled on the first rotating shaft, the end of the first hose is located at the bottom of the coolant tank and fixed to the first rotating shaft, a first torsion spring is sleeved on the first rotating shaft, one end of the first torsion spring is fixed to the bottom of the coolant tank, and the other end of the first torsion spring is fixed to the first rotating shaft.

[0006] Preferably, a second rotating shaft is rotatably connected inside the heat sink. The second rotating shaft is cylindrical in shape. The second flexible hose is a steel wire hose, which is coiled around the second rotating shaft. The end of the second flexible hose passes through the side wall of the second rotating shaft and extends downward into the coolant tank. A second torsion spring is sleeved on the second rotating shaft. One end of the second torsion spring is fixed to the bottom of the heat sink, and the other end of the second torsion spring is fixed to the second rotating shaft.

[0007] Preferably, the fan is coaxially fixed to the upper end of the second rotating shaft.

[0008] Preferably, the sheath has a partition arranged radially inside.

[0009] Preferably, the first hose is slidably and sealed to the coolant tank.

[0010] Preferably, the second hose is slidably and sealed to the coolant tank.

[0011] Preferably, the cross-section of the first hose is rectangular.

[0012] Preferably, the cross-section of the second hose is rectangular.

[0013] The beneficial effects of this invention are as follows: Compared with the prior art, this invention utilizes wind power to twist the cable and the sheath simultaneously, discharging the coolant inside the sheath. At the same time, the sheath pulls the first and second hoses out of the coolant tank and the heat sink. The first and second torsion springs store energy, and the second rotating rod drives the fan to rotate and cool the discharged coolant. After the wind power disappears, the first and second torsion springs rewind the first and second hoses, thereby achieving cable uncoupling. During the cable uncoupling process, a negative pressure is formed inside the first cavity, the one-way inlet valve opens, and the one-way outlet valve closes, drawing in coolant into the first cavity. Cooling of the first cavity can be achieved without the need for a coolant pump, thus achieving cable cooling and efficient cooling inside the tower. It also enables automatic cable uncoupling.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The reference numerals in the accompanying drawings include: tower 10, cable 20, sheath 30, one-way inlet valve 31, one-way outlet valve 32, baffle 33, coolant tank 40, first shaft 41, first hose 42, heat sink 50, second shaft 51, second hose 52, fan 53, air inlet pipe 54, and air outlet pipe 55.

[0018] Example 1:

[0019] A high-efficiency wind turbine silo cooling device, such as Figures 1-2 As shown, the structure includes a sheath 30, a coolant tank 40, and a heat sink 50. The sheath 30 is fixed to the outer periphery of the cable 20 and is made of rubber, allowing it to be twisted. The sheath 30 extends from the lower end of the cable 20 to the upper end. A cylindrical cavity is provided on the inner wall of the sheath 30. One or more partitions 33 are radially arranged inside the cavity of the sheath 30, thereby uniformly dividing the cavity of the sheath 30 into multiple sections. Each section of the sheath 30 is provided with a coolant tank 40 and a heat sink 50. The coolant tank 40 and the heat sink 50 are both fixed to the inner wall of the wind turbine tower 10 and are provided corresponding to each section of the sheath 30.

[0020] The lowest cavity of the sheath 30 is named the first cavity. The first cavity is connected to a first hose 42 via a one-way inlet valve 31. The first hose 42 is a steel wire hose with a rectangular cross-section. A first shaft 41 is rotatably connected to the bottom center of the coolant tank 40. The first hose 42 is coiled around the first shaft 41, and the end of the first hose 42 is located at the bottom of the coolant tank 40 and fixed to the first shaft 41. A first torsion spring is sleeved on the first shaft 41. One end of the first torsion spring is fixed to the bottom of the coolant tank 40, and the other end of the first torsion spring is fixed to the first shaft 41. The first hose 42 is slidably sealed to the coolant tank 40. Thus, the first cavity is connected to the inside of the coolant tank 40 via the one-way inlet valve 31 and the first hose 42.

[0021] The first cavity is connected to a second flexible hose 52 via a one-way outlet valve 32. The second flexible hose 52 is also a steel wire hose with a rectangular cross-section. A second rotating shaft 51 is rotatably connected to the bottom center of the heat sink 50. The second rotating shaft 51 is cylindrical. The second flexible hose 52 is coiled around the second rotating shaft 51 in the middle. The end of the second flexible hose 52 passes through the side wall of the second rotating shaft 51 and extends downward into the coolant tank 40. A second torsion spring is fitted on the second rotating shaft 51. One end of the second torsion spring is fixed to the bottom of the heat sink 50, and the other end of the second torsion spring is fixed to the second rotating shaft 51. The second flexible hose 52 is slidably sealed to the coolant tank 40. A fan 53 is installed inside the heat sink 50. The fan 53 is coaxially fixed to the upper end of the second rotating shaft 51. The inlet end of the fan 53 is connected to the outside through an air inlet pipe 54, and the outlet end of the fan 53 is connected to the outside through an exhaust pipe 55. The outlet end of the exhaust pipe 55 is located above the inlet end of the air inlet pipe 54.

[0022] In this embodiment, the winding principle of the first hose 42 and the second hose 52 is similar to that of a measuring tape.

[0023] The specific implementation process is as follows:

[0024] When the cable 20 is not twisted, the first cavity is filled with coolant; the first hose 42 and the second hose 52 are respectively wound around the first shaft 41 and the second shaft 51 under the action of the first torsion spring and the second torsion spring.

[0025] When the cable 20 is twisted by the wind, the cable 20 causes the sheath 30 to twist as well. The cavity is squeezed, the one-way inlet valve 31 closes, the one-way outlet valve 32 opens, and the coolant inside the sheath 30 is squeezed out and discharged into the coolant tank 40 through the second hose 52.

[0026] At the same time, during the twisting process of the cable 20, the sheath 30 will pull the wound first hose 42 and second hose 52 outward, which can realize the twisting of the cable 20 and the sheath 30, while the first torsion spring and the second torsion spring store energy.

[0027] When the wind disappears, the first torsion spring and the second torsion spring will rewind the first hose 42 and the second hose 52, thereby unwinding the cable 20. During the unwinding process, a negative pressure is formed inside the first cavity, the one-way inlet valve 31 opens, the one-way outlet valve 32 closes, and coolant is drawn into the first cavity.

[0028] The cable 20 is intermittently twisted and reset repeatedly, thereby achieving intermittent intake and discharge of coolant inside the first cavity. Cooling of the first cavity, i.e., cooling of the cable 20, can be achieved without the need for a coolant pump.

[0029] During the twisting of the cable 20, the sheath 30 pulls the first hose 42 and the second hose 52 outward, and the first shaft 41 and the second shaft 51 rotate. The rotation of the second shaft 51 drives the fan 53 to rotate. When the coolant is discharged into the second hose 52, the coolant can be cooled down, thereby ensuring that the coolant can always play a cooling role.

[0030] The principle of the other cavities above the first cavity is the same as that of the first cavity. In this embodiment, the purpose of setting the partition 33 is to prevent the coolant from being discharged under the action of gravity.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of protection of the claims.
