[0002] When replacing traditional wind speed and wind direction sensor devices, people must climb to the platform at the top of the tower and stand on the platform to replace the wind speed and wind direction sensors that need to be identified. Identification is usually required four times a year. The risk of climbing is very high, and improper operations can easily lead to accidents and the risk of people falling.

[0003] Chinese patent publication number CN208596173U discloses a wind sensor tower with automatic lifting function, including a tower body, a plurality of fixed pulleys are fixed on the top of the tower body, a mounting ring that can be lifted up and down is sleeved on the surface of the tower body, a wind sensor is arranged on the mounting ring, the top of the mounting ring is connected to one end of a suspension rope, the other end of the suspension rope is passed around the fixed pulley and connected to a counterweight, the bottom of the mounting ring is connected to one end of a traction rope, the other end of the traction rope is wound around a winding wheel, and the winding wheel is connected to the output end of a winch.

[0004] However, when the above device is actually used, the rope may break due to long-term use, and the mounting ring may fall directly from the top of the wind tower, which may cause harm to pedestrians. At the same time, in winter, the mounting ring may freeze to the top of the wind tower due to the low temperature, making it impossible for the mounting ring and the anemometer to fall from the top of the wind tower. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the above-mentioned prior art that the rope may break due to long-term use, the mounting ring may fall directly from the top of the wind tower, which may cause harm to pedestrians, and in winter, the mounting ring may freeze to the top of the wind tower due to low temperature, resulting in the mounting ring and the anemometer being unable to fall from the top of the wind tower.

[0006] The invention provides an automatically lifting wind tower, comprising a wind tower body, a wind tower top plate, a movable plate that can move up and down, an anemometer for measuring wind speed, a transmission device for driving the movable plate to move up and down, a slide rail for guiding the movable plate, and an anti-falling device for preventing the movable plate from accidentally falling off. The wind tower fixed plate is connected to the top of the wind tower body, the movable plate is arranged inside the wind tower top plate, the anemometer is fixedly connected to the movable plate, a transmission device is arranged on the lower surface of the movable plate, and the transmission device is fixedly connected to the movable plate, the slide rail is vertically arranged on one side of the movable plate, and the slide rail is connected to the transmission device, the bottom end of the slide rail is fixedly connected to the wind tower body, the top end of the slide rail is connected to the lower surface of the wind tower top plate, and the anti-falling device is also arranged on the lower surface of the wind tower top plate and is located on one side of the slide rail.

[0007] In the technical solution of the utility model, when the movable plate and the anemometer are lifted to the top of the wind tower by the transmission device, the movable plate will synchronously drive the slider to move upward, and when the movable plate is lifted to the inside of the top plate of the wind tower, the slider will also move to the inside of the anti-falling device at the top of the slide rail. After the slider moves to the top of the slide rail, the anti-falling device can be used to clamp the slider from both sides of the slider, and then the position of the movable plate and the anemometer is fixed by the slider, so as to solve the shortcomings mentioned in the technical background that the rope may break due to long-term use, and the mounting ring may fall directly from the top of the wind tower, which may cause harm to pedestrians.

[0008] When the temperature is too low in winter, when the movable plate needs to move up and down, the heat generated by the electric heating plate when working can be transferred to the fixed block through the heat conduction plate, and then the heat is transferred to the slider through the fixed block. When the temperature of the slider rises, the snow and ice frozen around the slider will melt, avoiding the slider and the slide rail from freezing together due to the slider being too high and the temperature being too low, causing the movable plate to be unable to move up and down. This is used to solve the problem mentioned in the technical background that in winter, the mounting ring may be frozen to the top of the wind tower due to the low temperature, causing the mounting ring and the anemometer to be unable to fall from the top of the wind tower.

[0009] Preferably, the slide rail adopts a "T" slide rail, the transmission device is slidably connected to the inside of the slide rail, and the top of the slider is connected to the movable plate, so when the movable plate moves up and down, the movable plate will drive the slider to move up and down synchronously. Because the slider is connected to the movable plate, and the slider is slidably connected to the inside of the slide rail, when the movable plate moves up and down, the slider will guide the movable plate to prevent the movable plate from tilting when it moves up and down.

When the motor rotates forward, the rope will be wound around the output shaft, and the length of the rope will be reduced, thereby driving the moving plate to move up. Conversely, when the motor reverses, the rope will be untied from the output shaft, the length of the rope will increase, and the moving plate will slide down due to its own weight.

[0011] Preferably, the anti-falling device includes an outer shell, an electromagnet, a guide rod, a spring, a sliding plate, a connecting rod, a fixed block, an armature and a heating assembly. The outer shell used is a "concave" shaped outer shell, and the upper surface of the outer shell is fixedly connected to the lower surface of the wind tower top plate, the electromagnet is transversely connected to the center position of the inner side plate of the outer shell, the two guide rods are symmetrically connected transversely on both sides of the electromagnet with the electromagnet as the center, the two guide columns are both provided with springs, the sliding plate used is a "U" shaped sliding plate, and the sliding plate is transversely connected to the inside of the outer shell, when the moving plate moves to the top of the wind tower, it will drive the slider to move synchronously to the top of the slide rail, and the two ends of the "concave" shape can just wrap the slider from both sides of the slider, thereby fixing the slider and the moving plate.

[0012] Preferably, a group of connecting rods are connected to the inner walls of the two protruding ends of the sliding plate, one end of the two groups of connecting rods is hinged to the sliding plate, and the other ends of the two groups of connecting rods are hinged to the fixed blocks, and the two fixed blocks are symmetrically connected to the side plates on the inner sides of the two protruding ends of the outer shell body with the electromagnet as the center, and the armature is fixedly connected to the outer surface of the sliding plate at a position corresponding to the electromagnet, the mounting shell of the heating component is arranged on one side of the outer shell body, and the heat conducting plate of the heating component is connected to the fixed block, and when the movable plate moves back and forth under the action of the electromagnet, it will drive the fixed block to move laterally to ensure that the fixed block can clamp or release the slider, so that the movable plate can drive the anemometer to move up and down under the action of the transmission device, or the movable plate can be fixed when the movable plate rises to the top of the wind tower to prevent the movable plate from suddenly falling from the top of the wind tower.

[0013] Preferably, the inner wall of the outer shell is connected with a heat-insulating material, and when the heating component heats the slider, the heat-insulating material retains a portion of the heat inside the outer shell, thereby ensuring that the temperature inside the outer shell is kept constant, so as to avoid the temperature inside the outer shell being too low in winter, thereby causing the electromagnet to malfunction.

After the temperature of the slider increases, the snow and ice around the slider will be melted, thereby preventing the slider and the slide rail from freezing together due to the slider being too high and the temperature being too low, causing the movable plate to be unable to move up and down.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The transmission device drives the anemometer to move up and down, and then the anemometer is inspected and repaired, which avoids the traditional method of workers climbing to the top of the wind tower to inspect the anemometer, effectively avoids the risk of personnel falling, and reduces the labor intensity of the staff;

[0017] 2.

DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are described in detail.

[0026] like Figure 1 As shown, an automatically lifting wind tower comprises a wind tower body 1, a wind tower top plate 2 fixedly connected to the top of the wind tower body 1, a slot is provided on one side of the wind tower top plate 2, a movable plate 3 which can move up and down is slidably connected in the slot on one side of the wind tower top plate 2, an anemometer for measuring wind speed is fixedly connected to the movable plate 3 by a bracket, when the movable plate 3 is driven up and down by the transmission device 5, the anemometer will also move up and down synchronously with the movable plate 3, when the movable plate 3 is lifted to the slot on one side of the wind tower top plate 2, the anemometer can perform corresponding measurement work.

[0027] like Figure 1 As shown, a transmission device 5 is provided at the bottom of the movable plate 3, and the transmission device 5 is fixedly connected to the lower surface of the movable plate 3. When the movable plate 3 moves up and down, the transmission device 5 will also move up and down together with the movable plate 3. The slide rail 6 is vertically arranged on one side of the wind tower body 1, and the bottom end of the slide rail 6 is fixedly connected to the wind tower body 1, and the top of the wind tower is fixedly connected to the wind tower top plate 2, and the slider 56 of the transmission device 5 is slidably connected to the inside of the slide rail 6 to ensure that the movable plate 3 will not tilt when it moves up and down driven by the transmission device 5.

[0028] like Figure 2As shown, the transmission device 5 includes a protective cover 51, a driving motor 52, a first pulley 53, a second pulley 54, a rope 55 and a slider 56. The protective cover 51 is fixedly connected to the lower surface of the movable plate 3, and the driving motor 52 is arranged inside the protective cover 51. The protective cover 51 can be waterproof and heat-insulating to ensure that the driving motor 52 will not be directly hit by rain or snow during operation. At the same time, it can be ensured that the driving motor 52 will not fail to work due to low temperature in winter. The driving motor 52 used is preferably a servo motor. The servo motor can ensure stable speed and efficiency when running at low speed to ensure that the movable plate 3 will not suddenly rise or fall when moving up and down.

[0029] like Figure 2 As shown, the first pulley 53 is arranged on one side of the protective cover 51, and the first pulley 53 is fixedly connected to the lower surface of the movable plate 3, so when the movable plate 3 moves up and down, the first pulley 53 will also follow the movable plate 3 and move up and down synchronously. The second pulley 54 is arranged parallel to one side of the first pulley 53, and the second pulley 54 is fixedly connected to the lower surface of the wind tower top plate 2. A rope 55 is arranged on the first pulley 53 and the second pulley 54, one end of the rope 55 is connected to the wind tower top plate 2, and the other end of the rope 55 passes through the side plate of the protective cover 51 and is connected to the output end of the drive motor 52.

[0030] like Figure 3 As shown, the top of the slider 56 is fixedly connected to the lower surface of the movable plate 3. When the movable plate 3 is driven up and down by the transmission device 5, the slider 56 will also be driven by the movable plate 3 to move up and down synchronously. The slider 56 is slidably connected to the inside of the slide rail 6. Therefore, when the slider 56 is driven up and down by the movable plate 3, the slider 56 will also guide the movable plate 3 through the slide rail 6. Therefore, when the movable plate 3 moves up and down, it will not tilt due to the action of the slider 56. The slide rail 6 used is a "T"-shaped slide rail 6. Therefore, when the slider 56 is driven up and down by the movable plate 3, the slider 56 will not fall off from the inside of the slide rail 6 to reduce the possibility of the movable plate 3 tilting.

[0031] like Figure 3As shown in the figure, when the moving plate 3 needs to move upward, the driving motor 52 rotates forward. Since one end of the rope 55 passes through the side plate of the protective cover 51 and is connected to the output end of the driving motor 52, when the driving motor 52 rotates forward, after the rope 55 is guided by the first pulley 53, the rope 55 passes through the side plate of the protective cover 51 and can be correctly wound around the output end of the driving motor 52, preventing the rope 55 from falling off the output end of the driving motor 52 and causing the moving plate 3 to suddenly fall. Since the other end of the rope 55 is connected to the top plate 2 of the wind tower, when the driving motor 52 rotates forward, the rope 55 is wound around the output end of the driving motor 52, and the length of the rope 55 exposed outside the protective cover 51 becomes shorter and shorter. Therefore, the moving plate 3 will gradually move upward under the pulling of the rope 55 until it rises into the interior of the top plate 2 of the wind tower under the drive of the rope 55.

[0032] As Figure 3 shown, conversely, when the moving plate 3 needs to move downward, the driving motor 52 can be reversed, the rope 55 falls off the output end of the driving motor 52, and the telescopic rope passes through the side plate of the protective cover 51 and is exposed outside the protective cover 51. The length of the rope 55 outside the protective cover 51 will gradually increase, and the moving plate 3 will also gradually move downward from the interior of the top plate 2 of the wind tower until the moving plate 3 drops to the required height, and then the power supply to the driving motor 52 is stopped to ensure that the moving plate 3 will not continue to move downward.

[0033] As Figure 3 shown, when the moving plate 3 moves upward to the vertex and is connected to the interior of the top plate 2 of the wind tower, the slider 56 will also move upward to the top of the slide rail 6 along with the moving plate 3. An anti-detachment device 7 is provided on one side of the top of the slide rail 6. Therefore, when the slide rail 6 is driven by the moving plate 3 to move upward to the top of the slide rail 6, the anti-detachment device 7 will clamp the slider 56 from both sides of the slider 56, and the position of the moving plate 3 is fixed through the slider 56, avoiding the method of using the driving motor 52 to fix the position of the moving plate 3 with the rope 55, reducing the tension on the rope 55, extending the service life of the rope 55, and reducing the risk of the moving plate 3 suddenly falling due to the sudden breakage of the rope 55.

[0034] As Figure 4 shown, a heating component 8 is provided on the outer side of the anti-detachment device 7. The upper surface of the heating component 8 is fixedly connected to the lower surface of the top plate 2 of the wind tower. The heating component 8 includes a mounting shell 81, an electric heating plate 82, and a heat conducting plate 83. The appearance of the mounting shell 81 is in the shape of a "U". Therefore, the anti-detachment device 7 can be wrapped in the inner recess at the front end of the mounting shell 81. The electric heating plate 82 is vertically arranged inside the mounting shell 81 and is fixedly connected to the side plate of the mounting shell 81, and both ends of the electric heating plate 82 are connected to an arc-shaped heat conducting plate 83.

[0035] As Figure 4As shown, one end of the heat conducting plate 83 is connected to the electric heating plate 82, and the other end of the heat conducting plate 83 passes through the side plate of the mounting shell 81 and the outer shell 71 of the anti-dropping device 7 and is connected to the fixing block 77 inside the anti-dropping device 7. Therefore, when the electric heating plate 82 works, the heat conducting plate 83 will transfer the heat generated by the electric heating plate 82 to the fixing block 77, and the fixing block 77 clamps the sliding block 56 from both sides of the sliding block 56. Therefore, the heat generated when the electric heating plate 82 works will be transferred to the sliding block 56 through the heat conducting plate 83 and the fixing block 77 to indirectly increase the temperature of the sliding block 56.

[0036] As Figure 4 shown, after the temperature of the sliding block 56 rises, the sliding block 56 will melt the rain or snow frozen around the sliding block 56 due to too low temperature. After melting, the position of the moving plate 3 is moved up and down through the transmission device 5 to avoid the sliding block 56 being frozen inside the slide rail 6 due to too low temperature, which will cause the moving plate 3 and the sliding block 56 to be unable to move up and down even when the transmission device 5 is turned on, and then the anemometer 4 cannot be repaired.

[0037] As Figure 5 shown, the anti-dropping device 7 includes an outer shell 71, an electromagnet 72, a guide post 73, a spring 74, a sliding plate 75, a connecting rod 76, a fixing block 77 and an armature 78. The outer shell 71 is a "concave" shaped outer shell 71. Therefore, the slide rail 6 and the sliding block 56 can be vertically arranged in the groove at the front end of the outer shell 71. The inside of the outer shell 71 is hollow. The electromagnet 72 is horizontally connected to the inner wall on one side of the outer shell 71. The guide posts 73 are symmetrically horizontally connected to both sides of the electromagnet 72 with the electromagnet 72 as the center, and springs 74 are sleeved on both guide posts.

[0038] As Figure 5 shown, the sliding plate 75 is horizontally connected inside the outer shell 71. The sliding plate 75 is also a "U" shaped sliding plate 75, and the extending direction of the sliding plate 75 is the same as the extending direction of the outer shell 71. Two groups of connecting rods 76 are hinged on the inner walls at both ends of the extending part of the sliding plate 75. One end of the connecting rod 76 is hinged to the sliding plate 75, and the other end of the connecting rod 76 is hinged with a fixing block 77. Therefore, when the sliding plate 75 moves back and forth, it will synchronously drive the fixing block 77 to move horizontally. The fixing block 77 is arranged on the inner walls at both ends of the extending part of the outer shell 71, and an armature 78 is fixedly connected to the position corresponding to the electromagnet 72 on the outer surface of the sliding plate 75.

[0039] As Figure 5As shown, when the anemometer 4 needs to be repaired and the movable plate 3 needs to be dropped, the electromagnet 72 can be energized. After being energized, the electromagnet 72 will generate magnetic force due to its own characteristics, and then begin to attract the armature 78. While pulling the armature 78, the sliding plate 75 will move together with the armature 78 in the direction of the electromagnet 72. While moving, the sliding plate 75 will use the connecting rod 76 to pull the fixed block 77 back to the inside of the outer shell 71. After the fixed block 77 is pulled away from both sides of the slider 56, the movable plate 3 can move up and down under the action of the transmission device 5.

[0040] like Figure 5 As shown, after the anemometer 4 is overhauled, the slider 56 rises with the moving plate 3 to the inside of the anti-drop device 7 at the top of the slide rail 6, and when the sliding plate 75 moves toward the electromagnet 72, the accumulated force of the spring 74 bounces the sliding plate 75 back to its original position. When the sliding plate 75 bounces back to its original position, the fixing block 77 is pushed out of the outer shell 71 through the connecting rod 76, and the slider 56 is clamped from both sides of the slider 56 to fix the position of the column slider 56, thereby indirectly fixing the position of the moving plate 3 through the slider 56.

[0041] The movement process of this embodiment is as follows: when the anemometer 4 needs to be repaired, the electromagnet 72 is started first. After being energized, the electromagnet 72 will generate magnetism due to its own characteristics, thereby starting to attract the armature 78, and the armature 78 will move in the direction of the electromagnet 72. Because the armature 78 is fixedly connected to the sliding plate 75, when the armature 78 moves, the sliding plate 75 will also move in the direction of the electromagnet 72, and then the sliding plate 75 will pull the fixed block 77 back to the inside of the outer shell 71 through the connecting rod 76. At this time, the movable plate 3 can move up and down under the action of the transmission device 5.

[0042] After the fixed block 77 releases the slider 56, the drive motor 52 reverses and unties the rope 55 from the output end. The rope 55 exposed outside the protective cover 51 will gradually increase, and then the movable plate 3 will gradually descend until it descends to the required position and then the anemometer 4 is inspected. After the inspection is completed, the drive motor 52 rotates forward, and the rope 55 is guided by the first pulley 53 and the second pulley 54 and then wound around the output end of the drive motor 52. At this time, the rope 55 exposed outside the protective cover 51 will gradually shorten, and then the movable plate 3 will gradually rise.

[0043] When the movable plate 3 rises to the inside of the wind tower top plate 2, the slider 56 will also move to the inside of the anti-falling device 7 at the top of the slide rail 6, and then the electromagnet 72 will be powered off. After the magnetic force of the electromagnet 72 disappears, the spring 74 can move toward the electromagnet 72 through the sliding plate 75. The accumulated force of the spring 74 will bounce the sliding plate 75 back to its original position. When the sliding plate 75 bounces back to its original position, the fixing block 77 will be pushed out of the outer shell 71 through the connecting rod 76, and the slider 56 will be clamped from both sides of the slider 56 to fix the position of the column slider 56, thereby indirectly fixing the position of the movable plate 3 through the slider 56.

[0044] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
