Description

Technical Field

[0001] The utility model relates to the technical field of locking waterproof joints of wind turbine generators, and more specifically to a movable wrench for locking waterproof joints of wind turbine generators. Background Art

[0002] The generator of a wind turbine generator set is an important component that converts mechanical energy into electrical energy. The main cable passes through the waterproof connector of the generator junction box and is connected to the terminal. After the waterproof connector is locked, electrical energy output is achieved.

[0003] At present, the waterproof connectors of the junction box are designed to be arranged in multiple rows and columns, and the spacing between the waterproof connectors is very small. The junction box is pre-installed with waterproof connectors when it leaves the factory, and there is not enough space for conventional wrenches to lock them. The main cable assembly process is to first disassemble all the waterproof connectors of the junction box, then install the first waterproof connector, then thread the cable, and finally lock the first waterproof connector, and so on until the last waterproof connector is locked. Therefore, when conventional wrenches are used for locking waterproof connectors of wind turbine generators, all waterproof connectors must be disassembled first, and then installed and locked one by one, which is inefficient.

[0004] In summary, how to solve the low efficiency of locking the waterproof joint of a wind turbine generator with a conventional movable wrench is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a movable wrench for locking a waterproof joint of a wind turbine generator, which will not interfere with other waterproof joints during the process of locking the waterproof joint, and can improve work efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A movable wrench for locking a waterproof joint of a wind turbine generator, comprising:

[0008] handle;

[0009] The wrench head comprises a movable jaw and a fixed jaw, both of which are arc-shaped table structures. The fixed jaw is fixedly connected to the handle. The movable jaw is arranged opposite to the inner side wall of the fixed jaw and is spaced to form an opening. The movable jaw is movably connected to the handle to adjust the size of the opening. The opening is divided into a margin area and a clamping area along its axial direction. The clamping area is used to clamp the waterproof joint. The handle is arranged corresponding to the margin area so that when the clamping area clamps the waterproof joint, the handle does not interfere with other waterproof joints.

[0010] Preferably, the inner side wall of the fixed jaw is provided with a first groove, and the inner side wall of the movable jaw is provided with a second groove, and the opening ends of the first groove and the second groove are arranged opposite to each other to form the opening.

[0011] Preferably, the first groove and the second groove are both in a V shape.

[0012] Preferably, a connecting block is provided between the wrench head and the handle, the first end of the connecting block is fixedly connected to the outer wall of the fixed jaw, the first end of the connecting block is also movably connected to the outer wall of the movable jaw, the second end of the connecting block is clamped with the handle and the two are located on the same horizontal plane.

[0013] Preferably, a card block is provided at the second end of the connecting block, an elastic plug locking pin is provided on the card block, a card slot adapted to engage with the card block is provided at the end of the handle, and a socket for inserting the elastic plug locking pin is provided on the side wall of the card slot.

[0014] Preferably, a cavity is provided inside the connecting block, the movable jaw is connected to a guide shaft via a support plate, and the guide shaft is movably inserted into the cavity along the arrangement direction of the movable jaw and the fixed jaw, and the shaft pin can rotatably penetrate the side wall of the connecting block and extend into the cavity to be threadedly connected to the guide shaft.

[0015] Preferably, the handle is provided with a plurality of waist holes arranged at intervals along the axial direction thereof.

[0018] Preferably, the axial direction of the handle and the axial direction of the opening are arranged at a certain inclination angle.

[0019] The utility model provides a movable wrench for locking the waterproof joint of a wind turbine generator, and the wrench head is composed of movable jaws and fixed jaws that are relatively and spaced apart. Compared with conventional movable wrenches, a wider opening can be formed between the inner side walls of the movable jaws and the fixed jaws, both of which are arc-shaped structures. Therefore, in the process of clamping and locking waterproof joints of the same specification, the maximum distance between the outer side walls of the movable jaws and the fixed jaws of the present application is smaller than the maximum distance between the outer side walls of the two jaws of a conventional movable wrench. Even if the outer ring structure of the wrench head of the present application is smaller, the wrench head can avoid interference with other waterproof joints when clamping the waterproof joint. Moreover, the movable jaws and the fixed jaws, both of which are arc-shaped structures, have a small rotation radius during the rotation process of clamping the waterproof joint, thereby avoiding interference with other waterproof joints during the rotation process of the wrench head, thereby ensuring that the wrench head of the present application will not interfere with other waterproof joints during the process of locking the waterproof joint. In addition, the opening is divided into a margin area and a clamping area along its axial direction, and the handle is set corresponding to the margin area. Even if the handle is not set lower than the top of the clamping area, only the clamping area is used to clamp and lock the waterproof joint, so that the handle will not interfere with other waterproof joints during the rotation process, ensuring that the waterproof joint is locked. In summary, the movable wrench of the present application will not interfere with other waterproof joints during the locking process of the waterproof joint. When used in the locking operation of the waterproof joint of a wind turbine generator, it is only necessary to lock all the waterproof joints that have been passed through the cable one by one, without having to remove all the waterproof joints first and then install and lock them one by one, which reduces the number of times the waterproof joint is disassembled and assembled, and improves work efficiency.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The core of the utility model is to provide a movable wrench for locking the waterproof joint of a wind turbine generator, which will not interfere with other waterproof joints during the process of locking the waterproof joint, thereby improving work efficiency.

[0037] Please refer to Figure 1The present application provides an active wrench for locking a waterproof joint of a wind turbine generator, comprising a handle 1 and a wrench head 2, the wrench head 2 comprising an active jaw 21 and a fixed jaw 22, both of which are arc-shaped table structures, the fixed jaw 22 is fixedly connected to the handle 1, the inner side walls of the active jaw 21 and the fixed jaw 22 are arranged opposite to each other and are spaced to form an opening 23, and the active jaw 21 is movably connected to the handle 1 to adjust the size of the opening 23, the opening 23 is divided into a margin area 231 and a clamping area 232 along its axial direction, the clamping area 232 is used to clamp the waterproof joint, the handle 1 is arranged corresponding to the margin area 231, so that when the clamping area 232 clamps the waterproof joint, the handle 1 does not interfere with other waterproof joints.

[0038] It should be noted that the two jaws of a conventional movable wrench are both in the shape of long strips, while the movable jaw 21 and the fixed jaw 22 of the present application are both in the shape of an arc table. During processing, it is equivalent to widening the opening 23 formed between the inner side walls of the two jaws along the relative arrangement direction of the two jaws on the basis of a conventional movable wrench, and cutting the outer side walls of the two jaws into an arc shape. Therefore, in the case of adapting to the specifications of the waterproof connector to be clamped, the wrench head 2 structure composed of the movable jaw 21 and the fixed jaw 22 of the present application is more compact and suitable for the locking operation of the densely arranged waterproof connectors on the junction box. The movable jaw 21 is movably connected to the wrench to adjust the spacing between the movable jaw 21 and the fixed jaw 22, that is, to adjust the size of the opening 23, so as to meet the locking operation of waterproof connectors with different SW values, where the SW value refers to the minimum distance of the waterproof connector relative to the plane.

[0039] The movable wrench arranged with the above structure can form a wider opening 23 between the inner side walls of the movable jaw 21 and the fixed jaw 22, both of which are arc-shaped structures. Therefore, in the process of clamping and locking waterproof joints of the same specification, the maximum distance between the outer side walls of the movable jaw 21 and the fixed jaw 22 of the present application is smaller than the maximum distance between the outer side walls of the two jaws of the conventional movable wrench. Even if the outer ring structure of the wrench head 2 of the present application is smaller, the wrench head 2 can avoid interference with other waterproof joints when clamping the waterproof joint. In addition, the movable jaw 21 and the fixed jaw 22, both of which are arc-shaped structures, have a small rotation radius during the rotation process of clamping the waterproof joint, thereby avoiding interference with other waterproof joints during the rotation process of the wrench head 2, thereby ensuring that the wrench head 2 of the present application will not interfere with other waterproof joints during the process of locking the waterproof joint. Figure 4 In addition, the opening 23 is divided into a margin area 231 and a clamping area 232 along its axial direction, and the handle 1 is arranged corresponding to the margin area 231. Even if the handle 1 is not arranged below the top of the clamping area 232, the waterproof connector can be clamped and locked by only using the clamping area 232, so that the handle 1 will not interfere with other waterproof connectors during the rotation process, thereby ensuring that the waterproof connector is locked. Figure 5In summary, the movable wrench of the present application will not interfere with other waterproof connectors during the process of locking the waterproof connector. When used in the locking operation of the waterproof connector of a wind turbine generator, it is only necessary to lock all the waterproof connectors that have been passed through the cables one by one, without having to remove all the waterproof connectors first and then install and lock them one by one, thus reducing the number of times the waterproof connectors are disassembled and assembled, and improving work efficiency.

[0040] In order to further optimize and realize that the wrench head 2 does not interfere with other waterproof connectors during the process of locking the waterproof connector, based on the above embodiment, please refer to Figure 2 A first groove 24 is formed on the inner side wall of the fixed jaw 22 , and a second groove 25 is formed on the inner side wall of the movable jaw 21 . The opening ends of the first groove 24 and the second groove 25 are arranged opposite to each other to form an opening 23 .

[0041] Specifically, the inner side walls of the fixed jaw 22 and the movable jaw 21 having an arc-shaped table structure are arc-shaped walls. The arc-shaped inner wall of the fixed jaw 22 is deepened toward its outer wall to set a first groove 24, and the arc-shaped inner wall of the movable jaw 21 is deepened toward its outer wall to set a second groove 25. The first groove 24 and the second groove 25 are relatively arranged to form an opening 23, so as to further increase the distance between the inner side walls of the fixed jaw 22 and the movable jaw 21, that is, to further increase the width of the opening 23, so that the clamping area 232 of the opening 23 can clamp the waterproof joint in the process of clamping the waterproof joint without moving the movable jaw 21 a large distance away from the fixed jaw 22, thereby reducing the space occupied by the outer ring of the wrench head 2 when clamping the waterproof joint, thereby effectively ensuring that the wrench head 2 will not interfere with other waterproof joints in the process of locking the waterproof joint.

[0042] Preferably, please refer to Figure 2 The first groove 24 and the second groove 25 are both V-shaped, so that the fixed jaw 22 and the movable jaw 21 have two surfaces in contact with the waterproof joint when clamping the waterproof joint, thereby increasing the force-bearing area and improving the clamping effect.

[0043] It should be noted that as the capacity of wind turbines changes, the outer diameter of the main cable will become larger and larger, the selected waterproof connector will also become larger and larger, and the required locking torque will become larger and larger. The conventional movable wrench has a short force arm, so more force needs to be applied to lock the waterproof structure. Therefore, when locking larger waterproof connectors, it is necessary to use a force rod to lock them. However, whether the conventional movable wrench is used for locking alone or with a force rod, the torque applied cannot be quantified, and whether it is actually locked is still a subjective judgment and cannot be tested, resulting in different locking degrees when different operators lock the same waterproof connector.

[0044] In order to make the movable wrench of the present application meet the torque locking requirements of waterproof connectors of different specifications and sizes, and meet the locking quantized torque requirements of waterproof connectors, on the basis of the above embodiments, please refer to Figure 2 and Figure 3 A connecting block 3 is provided between the wrench head 2 and the handle 1, the first end of the connecting block 3 is fixedly connected to the outer wall of the fixed jaw 22 and movably connected to the outer wall of the movable jaw 21, and the second end of the connecting block 3 is clamped with the handle 1 and the two are located on the same horizontal plane.

[0045] It can be understood that the wrench head 2 is connected to the handle 1 through the connecting block 3, the first section of the connecting block 3 is fixedly connected to the wrench head 2, and the second section is detachably connected to the handle 1 through a snap-on structure, so that the type of handle 1 can be selectively replaced. In this way, when the handle 1 adopts a conventional handle 1, even if the applied torque cannot be quantified, it can also be applied to the locking operation of waterproof joints with smaller locking torque, i.e., small-sized waterproof joints; when the handle 1 adopts a torque wrench, the torque wrench can quantify the applied torque, i.e., the torque wrench will stop rotating when it reaches the set value, so as to meet the torque locking requirements of waterproof joints of different specifications and sizes, i.e., large and small-sized waterproof joints, and at the same time ensure that the locking degree of all waterproof joints is consistent.

[0046] It should be noted that the connection block 3 and the handle 1 are located on the same horizontal plane, which can not only effectively transmit the torque of the handle 1 to the wrench head 2, but also ensure that the connection block 3 does not interfere with the waterproof joint during the rotation of the handle 1.

[0047] Considering the specific implementation method of the clamping structure between the connecting block 3 and the handle 1, based on the above embodiment, please refer to Figure 2 and Figure 3 , a clamping block 31 is provided at the second end of the connection block 3, and an elastic plug locking pin 32 is provided on the clamping block 31. A clamping slot 13 adapted to be clamped with the clamping block 31 is provided at the end of the handle 1, and a plug hole 14 for inserting the elastic plug locking pin 32 is provided on the side wall of the clamping slot 13. In this way, during the assembly of the handle 1, the clamping block 31 of the connection block 3 is inserted into the clamping slot 13 of the handle 1 until the elastic plug locking pin 32 is clamped into the plug hole 14 on the side wall of the clamping slot 13, and the assembly of the handle 1 is completed. The clamping structure composed of the clamping slot 13 and the clamping block 31 is not only firmly connected but also convenient for assembly and disassembly. The elastic plug locking pin 32 and the plug hole 14 form a positioning structure, which can clamp and position the clamping block 31 and the clamping slot 13 to ensure that the handle 1 and the connection block 3 are assembled in place.

[0048] Considering the implementation method of movable jaw 21 being arranged relative to fixed jaw 22, based on the above embodiment, please refer to Figure 6A cavity is provided inside the connecting block 3, and the movable jaw 21 is connected to a guide shaft 34 through a support plate 35, and the guide shaft 34 is movably inserted into the cavity along the arrangement direction of the movable jaw 21 and the fixed jaw 22, and the shaft pin 33 can rotatably penetrate the side wall of the connecting block 3 and extend into the cavity to be threadedly connected with the guide shaft 34.

[0049] Specifically, Figure 6 As shown, the fixed jaw 22 is fixedly connected to the front side of the first end of the connecting block 3, and the movable jaw 21 is movably connected to the first end of the connecting block 3 through a moving mechanism, and the moving mechanism is composed of a support plate 35, an axle pin 33 and a guide shaft 34. The interior of the connecting block 3 has a cavity for accommodating the moving mechanism, wherein the movable jaw 21 is connected to the end of the guide shaft 34 through the support plate 35. Preferably, a socket for the guide shaft 34 is provided on the rear side of the first end of the connecting block 3, and the guide shaft 34 extends into the cavity through the socket. Since the movable jaw 21 is arranged opposite to the fixed jaw 22, the axial direction of the guide shaft 34 is perpendicular to the fixed jaw 22, that is, the guide shaft 34 is arranged along the arrangement direction of the movable jaw 21 and the fixed jaw 22, so that the guide shaft 34 accurately guides the movement of the movable jaw 21. In order to realize the movement of the movable jaw 21 relative to the fixed jaw 22, preferably, a through hole is provided on the front side of the first end of the connecting block 3, and the shaft pin 33 is inserted into the cavity through the through hole. The outer peripheries of the shaft pin 33 and the guide shaft 34 are both provided with threads, such as Figure 7 and Figure 8 As shown, the two are connected by threaded cooperation, and the end of the shaft pin 33 extends out of the cavity of the connecting block 3, so that the operator can push the movable jaw 21 by rotating the shaft pin 33. The above structure is adopted to realize the movable jaw 21 relative to the fixed jaw 22. The structure is simple and the internal space of the connecting block 3 is fully utilized, so that the overall structure is small and compact.

[0050] Optionally, the clamping block 31, the connecting block 3 and the fixed jaw 22 are welded into an integrated structure, which is beneficial to improving the structural stability of the fixed jaw 22. Figure 7 As shown, in addition, the movable jaw 21, the support plate 35 and the guide shaft 34 are welded into an integrated structure, which is beneficial to improving the structural stability of the movable jaw 21. Figure 8 shown.

[0051] Optionally, a notch is provided at the top of the connecting block 3 at a position corresponding to the shaft pin 33, and the length of the notch is not less than the length of the external thread of the shaft pin 33. Figure 6 As shown, it is convenient for the operator to observe the external thread of the shaft pin 33 located in the connecting block 3 through the notch to control the degree of tightening.

[0052] Based on the above examples, please refer to Figure 1The handle 1 is provided with a plurality of waist holes 11 spaced apart along its axial direction, which can reduce the weight of the handle 1 to achieve a labor-saving effect, and the waist holes 11 can also play a role of suspension.

[0053] Based on the above examples, please refer to Figure 1 A non-slip rubber pad 12 is provided on the peripheral wall of the handle 1 to prevent slipping and enhance the hand feel.

[0054] Optionally, the axial direction of the handle 1 is perpendicular to the axial direction of the opening 23, that is, the axial direction of the handle 1 is perpendicular to the axial direction of the waterproof joint, so that the thrust applied to the handle 1 is converted into a torque on the waterproof joint to maximize the force saving effect. It should be noted that the longer the handle 1 is, the more force saving it is, provided that the structural strength requirements are met.

[0055] Optionally, the axial direction of the handle 1 is set at a certain inclination angle with the axial direction of the opening 23, that is, the axis of the handle 1 is set at a certain angle with the axis of the waterproof joint, and the end of the handle 1 away from the wrench head 2 is set in the locking and screwing direction, which is not only conducive to rotating the waterproof joint, but also can prevent the wrench head 2 from sliding and being damaged, thereby helping to improve work efficiency and save effort.

[0056] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0058] The above is a detailed introduction to a movable wrench for locking a waterproof joint of a wind turbine generator provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model.
