[0002] The columns of wind turbines are very tall. To facilitate maintenance by workers, existing columns of wind turbines are equipped with climbing aids to reduce the physical energy consumption of workers during climbing. However, due to the height of wind turbines, in cold areas or seasons, the higher you climb, the lower the temperature. At this time, the climbing aid will be stuck during the upward process due to the low temperature, and the control electrical appliances in the chassis will also run slowly or even fail due to the low temperature. Therefore, a heating device needs to be added to the climbing aid.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN219081780U is that the vertical cylinder in the installation structure cooperates with the thread below the vertical rod to rotate downward, thereby driving the first horizontal plate to slide downward inside the slide groove, thereby adjusting the position of the first horizontal plate. Then the first bolt passes through the groove on the outer wall of the first horizontal plate and is connected to the outer wall thread of the wind turbine climbing aid to avoid connection conflicts, ensure the normal installation of the low-temperature heating device of the wind turbine climbing aid, and eliminate usage limitations.

[0004] However, the device still has some shortcomings: the device is installed externally, the heat conduction efficiency is low, resulting in high energy consumption of the equipment, and the device lacks the function of heating the pulley block, and the pulley block will get stuck due to low temperature during the sliding process.

DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 4As shown, the utility model proposes a low-temperature heating device for a wind turbine climbing aid, comprising a chassis 1, a connecting pipe A9, a heat pipe 12, a spiral plate 14 and a circulating pump 15. An operating handle 103 is provided on the chassis 1, and a support plate 104 for carrying people is provided at the bottom of the chassis 1. Two sliders 2 are symmetrically provided in the chassis 1, and two upper and lower hollow shafts 3 are provided on each slider 2, and the hollow shafts 3 pass through the pulley 4. Two groups of upper and lower through holes 101 are symmetrically provided on the chassis 1, and each hollow shaft 3 is respectively located in the through hole 101 on the corresponding side and slidably connected with the inner wall thereof. A driving assembly for adjusting the hollow shafts 3 and the pulley 4 on the sliders 2 on both sides is provided in the chassis 1. The driving assembly comprises a hydraulic cylinder 8. A rack 6 is provided on the side where the sliders 2 on both sides are close to each other, and a gear 7 is provided on the chassis 1. The racks 6 on both sides are respectively located on both sides of the gear 7 and are meshed with the gear 7. The hydraulic cylinder 8 is connected to the chassis 1 and drives one of the sliders 2. The same end of the two hollow shafts 3 on the same slider 2 is connected through a connecting pipe A9. The hollow shafts 3 above the sliders 2 on both sides are connected through a connecting pipe B10, and the hollow shafts 3 below the sliders 2 on both sides are connected through a connecting pipe C11. The heat pipe 12 is located in the chassis 1 and connected to its inner wall. The heat pipe 12 stores a heat-conducting medium, which includes but is not limited to anhydrous ethanol, and a heating rod 13 is provided in the heat pipe 12 for heating the heat-conducting medium. The spiral plate 14 is located in the heat pipe 12, and the outer edge of the spiral plate 14 is connected to the inner wall of the heat pipe 12, and the inner edge of the spiral plate 14 is connected to the outer wall of the heating rod 13 to form a spiral channel in the heat pipe 12. The circulation pump 15 is connected to the chassis 1, and the circulation pump 15 is connected to one end of the spiral channel and the hollow shafts 3 below the sliders 2 on both sides, and the other end of the spiral channel is connected to the hollow shafts 3 above the sliders 2 on both sides. A control assembly is arranged in the chassis 1, a temperature sensor 102 is arranged on the chassis 1, the control assembly is electrically connected to the heating rod 13 and the circulation pump 15, and the temperature sensor 102 is electrically connected to the control assembly. A return pipe 121 and a discharge pipe 122 are arranged on the heat conducting pipe 12, which are respectively connected to the two ends of the spiral channel, wherein the other end of the return pipe 121 is connected to the connecting pipe B10, the discharge pipe 122 is connected to the input end of the circulation pump 15, and the output end of the circulation pump 15 is connected to the connecting pipe C11.

[0026] In this embodiment, when the chassis 1 is assembled on the climbing frame, it is only necessary to start the hydraulic cylinder 8 to pull back the slider 2 on one side, and the slider 2 on the other side is synchronously moved away under the transmission of the gear 7 and the rack 6, so that the distance between the pulleys 4 on both sides is enlarged, and then the chassis 1 is brought close to the climbing frame, so that the pulleys 4 on both sides are respectively located on both sides of the guide rod slot, and then the hydraulic cylinder 8 is started to push the slider 2 close, and at this time, the pulleys 4 on both sides are synchronously close and clamped on the guide rod. Since the pulley 4 is in contact with the guide rod, it is affected by the environment. If the temperature of the guide rod is too low, the pulley 4 is prone to jamming when sliding. When the temperature sensor 102 detects a low temperature, the control component controls the heating rod 13 and the circulation pump 15 to start. The heating rod 13 heats the anhydrous ethanol in the heat pipe 12. The circulation pump 15 extracts the high-temperature anhydrous ethanol and transports it along the connecting pipe C11 to the two hollow shafts 3 at the bottom. After passing through the two hollow shafts 3 at the bottom, the high-temperature anhydrous ethanol goes up along the connecting pipes A9 on both sides and passes through the two hollow shafts 3 at the top. Finally, it flows back into the heat pipe 12 through the connecting pipe B10 and the reflux pipe 121, thereby realizing circulating heating, raising the temperature of the pulley 4, and preventing the pulley 4 from being stuck due to the low temperature. In the process of the anhydrous ethanol in the heat pipe 12 heating up, the high temperature of the heat pipe 12 diffuses to the inside of the chassis 1 at the same time, thereby raising the temperature inside the chassis 1, ensuring the stable operation of each electronic control device in the chassis 1.

[0027] Embodiment 2

[0028] like Figure 1 and Figure 3 As shown, the utility model proposes a low-temperature heating device for a climbing aid of a wind turbine generator set. Compared with the first embodiment, the chassis 1 is slidably connected to four sealing plates 5 for sealing the corresponding side through holes 101, and each hollow shaft 3 passes through the corresponding side sealing plate 5 and is located on the central axis of the sealing plate 5. The width of the sealing plate 5 is twice the width of the through hole 101, so that when the spacing of the hollow shafts 3 is adjusted, the sealing plate 5 always blocks the through hole 101.

[0029] In this embodiment, the sealing plate 5 seals the through hole 101 to prevent the heat in the chassis 1 from being discharged along the through hole 101, so that the chassis 1 can achieve a good thermal insulation effect, thereby effectively reducing the power consumption of the heating structure.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
