When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present invention. On the contrary, they are only examples of the methods and devices consistent with some aspects of the present invention as detailed in the appended claims.

[0048] The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and above-mentioned drawings of the present invention are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here, for example, can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily need to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0049] As described in the background art section, during the specific installation process, at least two operators are required. One operator holds the anemometer firmly, and the other operator needs to use one hand to restrict the rotation of the bolt head at one end of the fastening bolt with a wrench, and use the other hand to screw the nut at the other end of the fastening bolt with another wrench, so as to fix the installation of the anemometer on the support rod or remove it from the support rod. Moreover, the space on the nacelle of the wind turbine is limited, and coupled with working at high altitude, due to some uncontrollable factors such as wind blowing, it is inconvenient for multiple people to carry out disassembly and assembly operations.

[0050] In view of the above problems existing in the prior art, the present utility model provides an auxiliary tool for disassembling and assembling an anemometer. The auxiliary tool for disassembling and assembling an anemometer provided by the present utility model includes a tool body and a limiting component. By providing a first contact surface on the tool body that matches a part of the peripheral wall of the anemometer body, the first contact surface is used to abut against the peripheral wall of the anemometer body. By arranging the limiting component on the tool body and providing a limiting portion on the limiting component that matches one end of the fastening component, the limiting portion is used to connect with one end of the fastening component for limiting. Hold the tool body and the anemometer body tightly with one hand at the same time, and through an external force, make the first contact surface abut against the peripheral wall of the anemometer body, and make the limiting portion connect with one end of the fastening component to restrict the rotation of the fastening component, so as to facilitate the other hand to screw and disassemble the other end of the fastening component through the tool, realizing the single-person disassembly and assembly of the anemometer on the wind turbine, reducing the installation difficulty and labor cost.

[0051] The technical solution of the present utility model will be described in detail below with specific embodiments in conjunction with the accompanying drawings. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0052] Please refer to Figures 1 to 3 As shown, the auxiliary tool for disassembling and assembling an anemometer provided in this embodiment can be used for auxiliary disassembly and assembly of the anemometer on the wind turbine. The anemometer includes an anemometer body 10, and a plurality of fastening components 20 are arranged on the peripheral side of the anemometer body 10. The fastening components 20 are used for fastening connection to the support frame 30 of the wind turbine. The auxiliary tool for disassembling and assembling an anemometer includes a tool body 100 and a limiting component 200.

[0053] The tool body 100 has a first contact surface 101 that matches a part of the peripheral wall of the anemometer body 10, and the first contact surface 101 is used to abut against the peripheral wall of the anemometer body 10.

[0054] The limiting component 200 is arranged on the tool body 100, and the limiting component 200 has a limiting portion 201 that matches one end of the fastening component 20, and the limiting portion 201 is used to connect with one end of the fastening component 20.

[0055] The tool body 100 is configured to make the first contact surface 101 abut against the peripheral wall of the anemometer body 10 by an external force, and connect the limiting portion 201 to one end of the fastening assembly 20 to limit the rotation of the fastening assembly 20.

[0056] In this embodiment, the anemometer includes an anemometer body 10 and an anemometry member. The anemometer body 10 can be cylindrical or of a rotary body shape. The anemometry member is installed on the anemometer body 10, such as a wind vane and a wind cup, which are respectively used to measure the wind direction, wind speed, etc. Among them, the peripheral side of the anemometer body 10 has a first flange, and a plurality of first mounting holes are arranged in a circumferential array on the first flange. The fastening assembly 20 is matched with the first mounting hole. The fastening assembly 20 can be composed of a bolt and a nut, and its specific model can be determined according to actual needs.

[0057] Moreover, the support frame 30 has a second flange that matches the first flange. A plurality of second mounting holes are arranged in a circumferential array on the second flange. The second mounting holes correspond to the first mounting holes, so that after the bolt passes through the first mounting hole and the second mounting hole in sequence, it is tightened with the nut, thereby firmly connecting the anemometer body 10 to the support frame 30 of the wind turbine. When disassembling, the nuts of each fastening assembly 20 are loosened in sequence.

[0058] The tool body 100 is used to be grasped together with the anemometer body 10 and provide an installation basis for the limiting assembly 200. It can be a housing-shaped or plate-shaped structure made of metal. A first contact surface 101 is provided on the tool body 100, and the first contact surface 101 matches a part of the peripheral wall of the anemometer body 10. Therefore, the first contact surface 101 is a concave partial arc surface or a concave partial rotary arc surface, which is determined according to the shape of the peripheral wall of the anemometer body 10.

[0059] The limiting assembly 200 is used to limit the rotation of the fastening assembly 20 when the fastening assembly 20 is screwed. It can be a block-shaped, rod-shaped, rotary body-shaped structure, etc. A limiting portion 201 is provided on the limiting assembly 200. The limiting portion 201 is used to match one end of the fastening assembly 20. It can be a sleeve, a screwdriver bit, etc. The limiting portion 201 is determined according to the head shape of one end of the fastening assembly 20.

[0060] Among them, the first contact surface 101 is used to face the peripheral wall of the anemometer body 10, that is, to face radially inward along the anemometer body 10, and the limiting portion 201 is used to face the fastening assembly 20 on the peripheral side of the anemometer body 10, that is, to face in a direction parallel to the axis of the anemometer body 10, such as along Figure 1As shown in the Y-axis direction, while the first contact surface 101 abuts against the peripheral wall of the anemometer body 10, the limiting portion 201 can be connected to one end of the fastening assembly 20. In this way, the operator can limit the rotation of the fastening assembly 20 while holding the tool body 100 and the anemometer body 10 with one hand, thereby freeing one hand to screw the other end of the fastening assembly 20.

[0061] It should be noted that at least the portion of the tool body 100 that contacts the peripheral wall of the anemometer body 10 should not be too thick, and can be designed as a thin plate structure to avoid the situation where one hand cannot hold it during operation.

[0062] Specifically, if Figure 4 As shown, when installing or disassembling the anemometer, the tool body 100 is moved onto the anemometer body 10, so that the limiting portion 201 on the limiting assembly 200 is aligned with and connected to one end of the fastening assembly 20 on the peripheral side of the anemometer body 10 to limit the rotation of the fastening assembly 20, and then the first contact surface 101 is abutted against the peripheral wall of the anemometer body 10 through the gripping force of one hand, thereby freeing up one hand to screw the other end of the fastening assembly 20 with a tool such as a wrench to complete the installation or disassembly.

[0063] It can be understood that, compared with multiple operators standing on the cabin, one operator holding the anemometer tightly, and another operator using both hands to screw the fastening assembly 20, the auxiliary tool for disassembling and assembling the anemometer provided in this embodiment uses one hand to hold the tool body 100 and the anemometer body 10 at the same time, and uses external force to make the first contact surface 101 abut against the peripheral wall of the anemometer body 10, and make the limit part 201 connected to one end of the fastening assembly 20 to limit the rotation of the fastening assembly 20, so as to facilitate the other hand to screw and disassemble the other end of the fastening assembly 20 through the tool, so that a single person can disassemble and assemble the anemometer on the wind turbine, reducing the difficulty of installation and labor costs. In addition, the risk of falling caused by crowding when multiple people stand in the same position to operate is reduced.

[0064] In a possible design, the tool body 100 includes a first body 110 and a second body 120 connected to the first body 110 , the first contact surface 101 is located on the first body 110 and on a side away from the second body 120 , and the second body 120 extends in a direction away from the first contact surface 101 .

[0065] Specifically, Figure 1 As shown, the first body 110 and the second body 120 are both plate-like structures, and the connection between the two is roughly L-shaped, which is convenient for the operator to hold the first body 110. The first contact surface 101 is located on the first body 110 and away from the side of the second body 120. The second body 120 is used to install the limit assembly 200.

[0066] Furthermore, in this embodiment, a gripping portion 111 is provided on the first body 110 , and the gripping portion 111 and the second body 120 are located on the same side of the first body 110 , and the gripping portion 111 is used for at least one finger to pass through and grip.

[0067] For example, Figure 1 As shown, the gripping portion 111 may be a through hole, and the through hole can allow at least one finger to pass through. In this way, when the operator holds the first body 110, the finger passes through the through hole, which can effectively prevent the first body 110 from slipping off the hand and play an anti-falling role.

[0068] Of course, the gripping portion 111 may also be formed of other shapes, such as a gripping portion that is convenient for adjacent fingers to grip, and any shape and structure that can play an anti-falling role is acceptable, and is not specifically limited in this embodiment.

[0069] Furthermore, in this embodiment, the limiting assembly 200 is connected to the second body 120 and is arranged to move relative to the second body 120 toward or away from the first contact surface 101. Figure 1 As shown, the limit assembly 200 can be connected to the second body 120 through a guide structure such as a slide rail and a guide rod. Figure 1 Reciprocating movement in the X-axis direction.

[0070] In this way, on the one hand, when the first body 110 and the anemometer body 10 are held at the same time, the limiting component 200 can be adaptively moved and adjusted along with the radial clearance of the fastening component 20 during the twisting process of the fastening component 20, so as not to interfere with the holding force between the first body 110 and the anemometer body 10. On the other hand, it can be adapted to limit the fastening components 20 of different radial sizes within a certain range, and has a wider range of applications.

[0071] More specifically, in this embodiment, the position limiting assembly 200 includes a screwing head 210 and a connecting member 220 connected to the screwing head 210, the position limiting portion 201 is located on the side of the screwing head 210 away from the connecting member 220, and the side of the connecting member 220 away from the screwing head 210 is slidably connected to the second body 120. The screwing head 210 can be a rotating body structure, and the connecting member 220 can be a rod-shaped, block-shaped, etc. The specific structural type, installation position, etc. of the screwing head 210 and the connecting member 220 can be determined according to actual needs and are not specifically limited in this embodiment.

[0072] For example, Figure 1 As shown, the screwing head 210 and the limiting portion 201 form a sleeve, which is used to match the external hexagonal bolt head. The screwing head 210 and the limiting portion 201 can also form a screwdriver bit, not shown in the figure, which is used to match the internal hexagonal bolt head, nut, etc.

[0073] Moreover, the screwing head 210 and the connecting member 220 can be connected by means such as screwing, clamping, plugging, etc. The connecting member 220 can be connected to the second body 120 through guiding structures such as slide rails and guide rods. Such a setting facilitates single-piece manufacturing and assembly.

[0074] Furthermore, in this embodiment, one side of the connecting member 220 facing the second body 120 has a first sliding portion 221, and one side of the second body 120 facing the connecting member 220 is provided with a second sliding portion 121 matching the first sliding portion 221, and the second sliding portion 121 is slidably connected to the first sliding portion 221.

[0075] In one example, as shown in combination with Figure 1 、 Figure 3 , the first sliding portion 221 is a slide rail, the second sliding portion 121 is a chute matching the slide rail, the slide rail and the chute are slidably connected, and the directions of both are arranged along the direction of approaching or departing from the first contact surface 101, so as to realize the sliding connection between the connecting member 220 and the second body 120.

[0076] In another example, not shown in the figure, the first sliding portion 221 is a chute, the second sliding portion 121 is a slide rail matching the chute, the slide rail and the chute are slidably connected, and the sliding connection between the connecting member 220 and the second body 120 can also be realized. Among them, the cross-sectional shapes of the slide rail and the chute can be rectangular, dovetail-shaped, etc.

[0077] It should be noted that, in order to prevent the connecting member 220 from freely detaching from the second body 120, a detachable limiting member such as a limiting screw can also be provided between the first sliding portion 221 and the second sliding portion 121.

[0078] Of course, the first sliding portion 221 and the second sliding portion 121 can also be replaced by other types of sliding and moving structures, as long as stable sliding can be achieved, and no specific limitation is made in this embodiment.

[0079] Still further, in this embodiment, at least one side of the connecting member 220 is provided with a protruding portion 222, and the protruding portion 222 is used to push the connecting member 220 to slide by a finger. Specifically, as shown in Figure 3 , the protruding portion 222 can be rod-shaped, block-shaped, etc., as long as it is convenient for finger pushing operation.

[0080] In this way, it is convenient for a finger to push the connecting member 220 to adjust the position of the screwing head 210, so that the limiting portion 201 quickly reaches the designated position to be connected to the fastening assembly 20. Exemplarily, as shown in Figure 3 , protruding portions 222 are oppositely arranged on both sides of the connecting member 220. For its specific shape, size, etc., it can be determined according to actual requirements, and no specific limitation is made in this embodiment.

[0081] Furthermore, in this embodiment, one side of the screwing head 210 facing away from the limiting portion 201 has a first connecting portion 211, and one end of the connecting member 220 facing the screwing head 210 has a second connecting portion 223 matching the first connecting portion 211, and the second connecting portion 223 is detachably connected to the first connecting portion 211.

[0082] In this way, by detachably connecting the screwing head 210 and the connecting member 220, screwing heads 210 of different models can be selected according to different models of the fastening assembly 20, and the applicable range is wider.

[0083] In one example, the first connecting portion 211 is a first plugging portion, the second connecting portion 223 is a second plugging portion matching the first plugging portion, and the second plugging portion is plugged with the first plugging portion. As Figure 1 shown, the first plugging portion can be a plugging post, the second plugging portion can be a plugging hole matching the plugging post, and the plugging post is plugged with the plugging hole, which is convenient for quick plugging and replacement.

[0084] In another example, not shown in the figure, the first plugging portion can be a plugging hole, the second plugging portion can be a plugging post matching the plugging hole, and the plugging post is plugged with the plugging hole, which can also achieve plugging. It should be noted that when the plugging post is plugged with the plugging hole, relative rotation between the screwing head 210 and the connecting member 220 cannot occur. In addition, in order to prevent the plugging post from freely detaching from the plugging hole, a locking member, such as a plug pin, an elastic tightening member, etc., can be provided between the plugging post and the plugging hole.

[0085] Of course, the first plugging portion and the second plugging portion can also be replaced by other types of quick-disassembly structures, such as screw connection, snap connection and other structures, which are not limited too much in this embodiment.

[0086] Optionally, in this embodiment, at least one assisting member 300 can also be included. The assisting member 300 is detachably connected to one side of the tool body 100. The assisting member 300 has a second contact surface 301 matching a part of the circumferential wall of the anemometer body 10, and the second contact surface 301 is used to surround the circumferential side of the anemometer body 10 and extend in a direction away from the first contact surface 101. The assisting member 300 is configured such that when the first contact surface 101 abuts against the circumferential wall of the anemometer body 10, the second contact surface 301 and the first contact surface 101 jointly abut against the circumferential wall of the anemometer body 10.

[0087] Among them, the assisting member 300 is used to increase the lever arm of the tool body 100 and prevent the limiting component 200 from driving the tool body 100 to rotate. It can be in the form of a strip, a plate, or other structures. One side of the assisting member 300 can be connected to one side of the tool body 100 through structures such as screwing or clamping. A second contact surface 301 is provided on the assisting member 300, and the second contact surface 301 also matches a part of the peripheral wall of the anemometer body 10. Therefore, the second contact surface 301 is a concave partial arc surface or a concave partial rotary arc surface, which is determined according to the shape of the peripheral wall of the anemometer body 10.

[0088] Specifically, when the first contact surface 101 abuts against the peripheral wall of the anemometer body 10, the second contact surface 301 and the first contact surface 101 jointly abut against the peripheral wall of the anemometer body 10. The second contact surface 301 increases the range of coverage of the peripheral wall of the anemometer body 10, that is, lengthens the lever arm. When the limiting component 200 is screwed to drive the tool body 100 to rotate, the assisting member 300 can more effectively prevent the tool body 100 from rotating, thereby reducing the holding force of the hand on the tool body 100 and the anemometer body 10.

[0089] It should be noted that the assisting member 300 and the tool body 100 are detachably connected, which is convenient for replacing different models of assisting members 300 according to different thicknesses of the anemometer body 10, and has a wider application range.

[0090] Exemplarily, as Figure 2 shown, assisting members 300 are provided on both sides of the tool body 100, which can cover an arc surface of half a circumference of the tool body 100. The specific shape, quantity, size, etc. of the assisting member 300 can be determined according to actual needs and are not specifically limited in this embodiment.

[0091] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the utility model disclosed herein. The present invention is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include known common knowledge or conventional technical means in the technical field not disclosed by the present invention. The specification and examples are only to be regarded as exemplary, and the true scope and spirit of the present invention are pointed out by the claims.

[0092] It should be understood that the present invention is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
